Exercise Induced Asthma Essay Example | Topics and Well Written Essays - 3000 words

Exercise Induced Asthma - Essay Example Asthma is chronic, or long term. (Exercise-Induced Asthma, 2006.) It is a condition of the lung and the main symptom is difficulty in breathing. The airways are extremely sensitive and when they are irritated, they react by narrowing or obstructing. As the air is restricted from moving, or circulating, wheezing, shortness of breath, chest tightness, and shortness of breath are symptoms that result. Risk factors include lifestyle (location, the weather, diet, etc.), environmental (smoking, allergens, and pollutants, etc.), use of antibiotics, exposure in the workplace, and genetics. Sawicki and Dovey (2005) report, "Children with one asthmatic parent are 2.6 times more likely to have asthmaMaternal asthma appears to make a bigger contribution than paternal asthma to asthma in offspring; one study found a frequency of atopic manifestations (including atopic asthma) of 44 percent in children whose mothers had atopic asthma compared to only 25 percent of children whose fathers had atopic asthma." Factors that can exacerbate asthma include respiratory tract infections resulting from viruses, allergens (dust mites, pets, pollens, indoor contaminants, etc.), stress, and Last Name 3 exercise. Exercise is one of the most common triggers. When exercise triggers asthma attacks, this is known as exercise-induced asthma, or EIA. 7-10 percent of school children are affected by asthma and is a major reason for missed school days.

Linux Assignment Example | Topics and Well Written Essays - 1000 words

Linux - Assignment Example Enterprise version of Red Hat supports both server and workstation systems, which eradicates the compatibility issues that could have occurred if other versions may have used. Various different flavors of Red Hat make it beneficial, which can be purchased depending on the services that are required. For a full working IT department in an organization a simple version of customer support can be also be purchased for reducing cost. A complete version of support is also available upon requirement. When it comes to reliability, Red Hat Linux is considered to be the most stable and reliable Operating System. (Negus, & Boronczyk, 2008, p. 191-192)The main disadvantage of using Red Hat is that it is not free. Even downloadable version also involves cost and also subsequent support services. There are various versions different versions of Red Hat are available in the market. These version can be purchased directly from Red Hat Inc or through there distributors. They are as follows: Workstat ions Specifications Basic Workstation Dual CPU supports, memory support is unlimited, no virtualization available Multi OS Workstation Dual CPUs, unlimited memory, and virtualization available Server Specifications Red Hat Enterprise Linux Dual CPU server supports. Available for both 32bit and 64 bit architecture. Support available in three forms basic, standard and premium Has four virtual guests support Its advance version support server of all sizes along with unlimited virtual guests and storage Community Enterprise Operating System (CentOS) CentOS was developed by CentOS project community using the source code of commercial Linux (Red Hat). (Baclit,  2009, p.  xxi-xxii) The purpose behind this development was to provide a free and stable version of commercial Linux distribution and also to keep up with the requirements of an Enterprise. CentOS enabled the Enterprise standard Linux for general public without requiring purchasing it or signing a service contract. CentOS have pre-installed GUI interfaces GNOME and KDE, which makes it easier for the user to use this system. For avoiding legal issues CentOS doesn’t included DVD player software in it which can be termed as its drawback, but users can install a DVD payer through internet if required. It is most popular distribution of Linux used for web servers today. (Membrey, Verhoeven, & Angenendt, 2009, p. xx-xx) Reliability, low cost and ease of use are major factors for its popularity. CentOS do not require different license for each machine as compared to Microsoft Windows products. Once loaded on disk, then can be installed on as many servers or workstation as the user required, allows greater compatibility between both without any major performance issues. Online blogs, forums and websites are general support for CentOS. Feedbacks around globe shows that people using CentOS as workstation or server had never faced any serious issue. Several people who have used this distribution reported that no serious issue has been faced in both of its form i.e. workstation and server. Novell Novell is a known Linux leader; its distribution is formally known as openSUSE. Major advantage this OS has is its relatively bug free distribution. During development, lots of concentration is given to compatibility and functionalities between openSUSE and programs that will interface is it. (McCallister,  2006, p.  255-256) OpenSUSE is considered as a bit difficult to be installed. But

Impact of Globalisation on International Business

Impact of Globalisation on International Business Globalisation refers to the process of interconnection among firms, people and governments of different countries (Lechner, 2009); economies from every country will become closer and interrelated through globalisation as foreign countries are a source of both production and sales for domestic companies. It is obvious that the globalisation has linked with international business as international business consists of all commercial transactions that take place between two or more countries such as sales, investments and transportation. Globalisation is very common in today’s world. It enables people to travel around the world by improving the transportation and it also helps people to do business in terms of purchase or sell products and services as well as pursuit of business leads. Moreover, globalisation also allows the international communication by improving the technology and it helps businessman to communicate easier with their business partner from other countries. Globalisation brings both positive and negative impacts on international business. There are rise in competition and rise in investment levels; whereas, the negative impacts on international business are the culture effect and also create more social problems child labour and slavery as well as environmental issues. Firstly, globalisation leads to rise in competition. This is because when companies expand their business to different countries this creates competition for domestic businesses in terms of the price, cost and quality of goods and services. This type of competition act as an opportunity for domestic companies to manufacture good quality of products and services and work effectively and efficiently in order to conduct business on a global scale. This will not only benefit the international business by increasing its market share but will also benefit the host country (foreign country where the company invests) as now people will have variety of products and services of good quality and affordable price due to rising competition. The domestic market of the country will become strong due to foreign company establishing in the country and contribute to economies GDP rate and growth. One of the examples of company that establishes and contributes to economies GDP rate and growth is General Motors (GM). GM is a multinational company which produces vehicles in United States. They had expanded their business in more than 120 countries including China (General Motors, 2015). When GM expanded its business to China in 2010 and its sales had grown approximately 50 percent in China and 15 percent in United States (Ketchen Short, 2012). Secondly, globalisation also affects the investment level in both host countries and home countries. Foreign Direct Investment which is also known as FDI refers to the long term investment owned by investors which can show the flow of capital between countries (Economic Online Ltd, 2015). According to Graham Spaulding (2005), the definition of FDI refers to physical investment that made by a firm to another country for building factory purpose. FDI of both host countries and home countries will increase by expanding businesses to other country through globalisation. FDI gives positive effects to host countries in several ways such as technological effect, employment effect and income effect. With FDI, people able to conduct business with new technologies and management skills; this is because FDI enables technology to transfer from developed countries to developing countries. Besides, training will be provided to the domestic workers for operating business with the new technology which will improve their management skills. Moreover, FDI also contribute in the income of host country as earning of FDI will be counted in the corporate tax (Loungani Razin, 2001). On the other hand, FDI will benefit the home countries by increasing capital in the balance of payment account. Expanding business from one country to other countries, the revenue from the foreign direct investment of the firm will increase the capital of the home country (Hill, 2001). For example, Toyota expands their business to Malaysia and the profit that Toyota gains from the foreign direct investment in Malaysia will send back to Japan as a capital in balance of payment. However, globalisation also views as threats for international business. One of the reasons is because globalisation enables people to share their culture. It is crucial for international business to understand the culture of other countries so that they can increase the productivity of their business. However, it is very difficult for international business to understand every culture of different countries as it is too broad; for instance, in Malaysia, besides of Malaysian culture, there are also other sub–cultures as Malaysia have many ethics. Usually, people are used to their own cultures yet some of them not able to accept others’ culture. One of the examples is when a Swedish company dealing with suppliers in Brazil, the Swedish company is unsatisfied with the attitude of suppliers in Brazil as they always delay the delivery which is urgent for the company; at the end, the Swedish company had no choice, they have to give penalty to the supplier in Brazil so that they can be more punctual (Daeri, et al., 2008). Another difficulty that faced by global business is the communication style. Every country has different style of communication either direct or indirect (Salacuse, 2005). Scandinavia and United Kingdom is one of the examples that show different communication style. The communication style in Scandinavia is direct which means they talk openly and straight to the point in the business whereas the communication style in United Kingdom is indirect where they respect their business partners and they don’t reject obviously. Therefore, it is difficult for businessman to identify the disagreement among British partners. Moreover, globalisation also causes an increase in social problems such as child labour and environment issues. The main purpose of doing business is to gain high profit, some of the businessman doesn’t care whether it is ethical or not. In order to save costs, some of the international businesses will recruit young children as labour and slaves (Pillai, 2011). Child labour often occurs in countries with high poverty rates due to the bad implementation of child labour laws (Hunt, 2013). For example, there are many cases of children trafficking to work in the cocoa farms in order to help support family in the chocolate industry of Western Africa. Some of them even sell to the farm owners or traffickers to work in a bad environment which may causes disease among the children (Mills, 2014). Furthermore, international businesses also cause the environmental issues in the globe such as air pollution and water pollution. International businesses increase the world carbon dioxide emission. The demand for car industry around the globe increased as people want vehicles for transportation purposes (Lacey, 2011). When demand for car industry is high, international business will manufacture vehicles in order to fulfill the customer needs; the more vehicles being used in the road, the higher the level of carbon dioxide emission. Rise of the world carbon dioxide emissions will lead to the air pollution. Other than that, extracting the rare-earth by international business also causes serious environmental issue. The process of extracting the rare-earth will cause water pollution and also radioactive in that area as the water will contain all types of toxic chemicals which may cause cancers. For example, the town in Inner Mongolia named Baotou, used to have crops and plantation but when the producer of rare-earth Baotou Iron and Steel Company starts to produce rare-earth at that place, plants unable to grow due to the radioactive and water pollution (Guardian News and Media Limited, 2012). In conclusion, globalisation can be seen as opportunities as well as threats for the international business. International business able to expand their business in other countries around the world meantime they are helping foreign countries to improve their living standard by providing variety choices and enhancing the quality of goods and services. Moreover, international business also able contributes to home country by increasing the profit of inflow of foreign direct investment through globalisation. On the other hand, globalisation also causes the international business to face cultures issues in term of attitudes, personal styles and communications. Besides that, social problems are also one of the threats for international business. In order to gain higher profit, some of the international businesses will conduct illegal activities such as recruiting child labour or slavery to minimize costs. Not only that, international business also pollute the environment badly especially rare-earth company.

Outline of Marriage in the Victorian Era Essay -- Victorian Era

Outline of Marriage in the Victorian Era In the Victorian era, marriage was not as romanticized or fairytale-like as depicted in many novels of the time. On the contrary, love actually played a very minor role in the majority of matrimonies that took place. An engagement was entered into as one would approach a business deal, and there were some generally accepted rules and guidelines to follow. The Rules * It was illegal to marry your deceased wife’s sister. You could marry first cousins, but attitudes changed towards the end of the 19th century, and this became frowned upon. * Victorians were encouraged to marry within the same class (remember the views on social mobility!). They could marry up, but to marry down meant marrying beneath yourself (Soames). * A woman entering into the institute of marriage had to be equipped with a dowry. The husband-to-be had to prove that he could support his new bride in the lifestyle she was accustomed to. * An unmarried woman could inherit money and property after she reached the age of 21, but once married, all control would revert to her husband. A woman could not have a will for her own personal possessions; since the control was in her husband’s power, he could distribute her property in any way he likes, even to his illegitimate children (if he has any). * Women married because they had a lack of options; they were not formerly educated, and were only instructed in domestic duties. They needed someone to support them, and were encouraged to marry and have children ("The Rules of Marriage"). The Courtship * Marriage was a carefully contemplated subject for a woman; since she would lose control over any possessions once married, it was not somethin... ...and helped to strengthen the family line, divorce was neither economically or socially practical. It would guarantee the family losing some of its strength and influence by giving up property and wealth.

Customer feedback Essay

The purpose of this report is help Dave Smith, the General Manager of the Landmark Hotel Auckland to improve the hotel’s current customer satisfaction measurement scheme by comparing a range of survey methods and recommends the most appropriate survey programme for the hotel. The report is broken down to two sections. The first section defines customer satisfaction and articulates the importance of measuring customer satisfaction. Section one also compares the functions of CSQs and TripAdvisor.com and introduces the content analysis method to the Landmark Hotel. The second part of the report defines measures of central tendency and dispersion and presents calculations from the guest survey spreadsheet provided. Based on summary table 1.1, the report briefly describes what the calculations mean to the hotel and produced a short recommendation. The report is produced with several limitations, which need to be addressed and overcome for future research. The recommendation made to Landmark Hotel under the first part, regarding the most appropriate research method was selected based on one of only two options. Further, since there is no standard ways to perform content analysis, the report simply presented what appeared to be the most logical procedure. Finally, the recommendation regarding internal marketing was much generalised due to word limits. PART A Defining Customer Satisfaction Customer satisfaction has been a topic of great importance in business practices. There is an overwhelming amount of outcome definitions characterising customer satisfaction, many of which have not yet been empirically tested. According to Yi (1993), some academics and practitioners define customer satisfaction from an outcome-based approach. Alternatively, other perceives and defines customer satisfaction as a process. Engel and Blackwell (1982) defined customer satisfaction as â€Å"an evaluation that the chosen alternative is consistent with prior beliefs with respect to the alternative† (p. 501). This definition is comparable with the disconfirmation theory, which proposes that guests are either satisfied or dissatisfied based on their expectations prior and subsequent to the purchase of the actual service experience. In this section, we are particularly concerned with the importance of measuring customer satisfaction. Fortunately, this question can be answered directly using the service-profit chain. The service-profit chain is simply a proposition of a series of linkages between â€Å"profitability, customer loyalty, and employee satisfaction, loyalty, and productivity† (Heskett, Jones, Loveman, Sasser & Schlesinger, 1994, p. 164). Customer satisfaction represents a crucial role in the service-profit chain because satisfaction is essentially a driver of customer loyalty (retention, repeated business and referrals), which directly impacts the profitability of a hospitality firm. Customer satisfaction is extremely important because it produces word-of-mouth, reduces operating overheads and facilitates price premiums (Denove & Power, 2006). Hospitality firms constantly look for more effective ways to measure customer satisfaction. Managers try to achieve greater accuracy in survey outcomes and use them to reliably address the gaps between management’s visions and the customer’s needs. Comparing Data Collection Methods Guest Feedback Forms Guest feedback forms, comment cards or customer satisfaction questionnaires (CSQs) are frequent tools used by most hotels for measuring customer satisfaction. Barsky (1992) stated two major disadvantages of guest comment cards, â€Å"poor construct validity†¦ poor statistical validity† (Barsky, 1992, p. 51). Yesawich (1978) also hypothetically considered CSQs as â€Å"more often than not, unreliable and statically invalid† (p, 72). Barsky (1992) further argues that guest comment cards may indicate customer satisfaction or dissatisfaction and related trends, but generally does not provide sufficient information for decision-making. Poria (2004) outlined several key advantages of using CSQs during guest complaints. Poria claimed that asking the guest to fill in CSQ would allow the staff extra time to resolve the problem and calms the guest. Tripadvisor.com In comparison with CSQs, Tripadvisor.com is an online interaction platform. Unlike the majority of quantitative methods, online customer reviews often articulate psychological changes of the hotel guests. According to Li, Ye and Law (2012), online reviews are more likely to convey guest’s true feelings, which make up for the missing information that was not captured by guest surveys. Tripadvisor.com and other eWOM platforms allow managers to interact with the guests, form one-to-one dialogues and perform qualitative content analysis. Content analysis is a systematic and objective approach to make inference from written data (Downe†Wamboldt, 1992). Like all qualitative research methods, content analysis is concerned with meanings and contextual aspects of a service experience. Content analysis can be described as an intensive exploration of a single customer review and typically, managers look for rich and vivid descriptions in the review, rather than generalised knowledge. However, content analysis and comparable qualitative research methods may lack scientific validity. Thus, it is difficult for managers to make reliable generalisations from a confined sample size. Research Methods and Design The Landmark Hotel needs to go beyond measuring performances and begin to understand perceptions and gain practical and context-dependent knowledge relating to specific guest experiences. I recommend the Landmark Hotel to focus on qualitative content analysis. Content analysis can be performed on online guest reviews as well as guest comment cards. Additionally, I recommend the use of open-ended question in guest comment cards in order to provide greater insights to the guest’s feelings (Lukas, Hair, Bush & Ortinau, 2005). According to Guthrie and Abeysekera (2006), content analysis requires a randomly selected sample, clearly defined criteria of analysis and a systematic data categorisation method, so that statistical analysis of the data can be performed. Downe†Wamboldt (1992) proposed an eight step procedure that the researcher should follow when conducting content analysis. These steps can be briefly described as 1) selecting unit of analysis, 2) defining the categories, 3) defining the categories, 4) testing for reliability and validity, 5) define or revise coding rules, 6) pre-testing the revised category schemes 7) data coding and 8) reassessing reliability and validity. According Marković and Raspor (2010), reliability of content analysis can be improved by developing coders for similar contents. Data coding allow researchers to measure frequency and percentage through tabulations, compute measures of central tendency and dispersion, test for difference, association and interdependence by performing t-tests and chi-square analysis using SPSS applications. Integration After the results have been analysed and interpreted, the researcher can choose to integrate and present the research outcomes within the hotel using an analytical report that is credible and believable. The report clearly defines the research problem/issue and the research methodology, which clearly articulates the objectives of the research, the research design used, descriptions of samples and the sampling methods and the how data are analysed. The results section is the most important section. This section should contain presentations of findings that are relevant to the research problem. The report should also contain a conclusion section, a recommendation and a limitation section which illustrates â€Å"extraneous events that place certain restrictions on the report† (Lukas, et al., 2005, p. 557). PART B Calculations and Definitions of Measurements Considering the guest survey spreadsheet, I have calculated the measures of central tendency and dispersion for each behavioural intention scale. For measures of central tendency, I have computed the mean, median and mode respectively. These measures are used as data reduction, which describes the set of responses through a single value. The mean is â€Å"the arithmetic average of the sample† (Lukas et al., 2005, p. 436). The mean is derived from the sum of all values pertained from the responses and divided by the exact number of valid responses. The median is â€Å"the middle value of a rank-ordered distribution† (Lukas et al., 2005, p. 436). The mode is defined as â€Å"the most common value in the set of responses to a question† (Lukas et al., 2005, p. 436). Standard deviation is a measure of dispersion. It is defined as â€Å"the average distance of the distribution values from the means† (Lukas et al., 2005, p. 438). The Excel function which I have used to compute the standard deviation of the data given was STDEV.S. STDEV.S estimates standard deviation from a sample rather than the entire population. The guest survey spreadsheet provided a number of intention statements aimed to obtain some ideas about guest experiences for certain aspects of the hotel. The management hoped to explore the guest’s intended behaviours as much as possible and the likelihood that guests will demonstrate predictable behaviour towards staying at the hotel in the foreseeable future. Table 1.1 shows that first and second rating scale demonstrated a lower average value in comparison with other rating scales. Evidently, service standard and staff competence to make guests feel accustomed during their stays did not meet the required expectations. Question eight also shows that on average, guests would not recommend the Landmark Hotel to others. Recommendations I postulate that service quality could be a major contributory factor to declines in booking rates. According to Parasuraman, Zeithaml and Berry (1985), there are ten determinants of service quality – competence, courtesy, reliability, responsiveness and understanding are five relatively important determinants directly influenced by staff. Additionally, empathy and assurance are additional components of service quality directly determined by hotel personnel, as proposed in the SERVQUAL scale (Parasuraman et al., 1988). For the purpose of restoring and improving service quality, I recommend an adjustment of focus onto internal marketing activities. According to George and Gronroos (1991), â€Å"internal market of employees is best motivated for service-mindedness and customer-oriented behaviour by a marketing-like approach, where marketing-like activities are used internally† (p. 86). Internal marketing is essentially a process of building a customer-oriented culture through training and achieving internal satisfaction. Internal marketing implies a number of activities besides training utilisation. Take, for example, regularly assessing internal satisfaction, empowerment, and the provision of adequate supervisory support, open communication policies and the development of a sound reward system all forms part of internal marketing activities that seeks to achieving continuous quality improvements.

Mary Maids Cleaning Service's objectives for the first four years of operation include: †¢ To create a service based company whose #1 goal is exceeding customer's expectations. †¢ To increase our number of clients served by 20% per year through superior service. †¢ To develop a sustainable home-based business, living off its own cash flow. †¢ The utilization of Mary Maids Cleaning Service on a regular basis by at least 30% of the  leads that contact us for more information. Product/ Services Description Situation Analysis MMCS will offer a wide range of services to the residential client, from general room cleaning to child/pet disasters which can go hand in hand. We will be going after the upper end of the market, typically the affluent whose spouse does not have a full-time job but chooses to do other things with his/her time, or  the two income family who chooses not to clean the home themselves. The business will be based out of the CEO Mary Blanktrip’s home office. Between the hours of 6AM-8AM Mary will work on  scheduling, estimates, inventory, ordering, and customer care management. The home office will include a computer, land phone line, and a fax machine. From 9AM-5PM Mary will clean homes until additional staff is hired. Mary Maids Cleaning Service's start-up costs include equipment needed for a home-based business (Exhibit 1),  initial legal fees, marketing fees, cleaning equipment and supplies, uniforms, and signs for employee vehicles. Employee expense is a commercial vacuum cleaner and assorted brooms, mops, and chemicals (biodegradable). SWOT Strengths CEO of Mary Maids Cleaning Services was a stay at home mom for 25 years †¢ Mary understands what it takes to balance home, children, and work †¢ Mary will achieve this high level of service through extensive training and a continuous learning process Weakness †¢ Major competition Molly Maids †¢ New company to the area †¢ First time business owner Opportunit y †¢ MMCS will be qualifying leads over the phone with estimates †¢ MMCS will arrange a  in house meetings to give estimates †¢ The sales process will begin through the qualification of leads generated from our marketing campaign Threats Balancing the whole business (includes office paper work & cleaning services) †¢ Getting customers to trust new business owner Target Market Mary Maids Cleaning Service will provide a residential house cleaning service for the upper end of the market. We will have two target customers: 1. The affluent that does not work, but is not inclined to do housework. To many a maid/house cleaner is a symbol of wealth, and this idea symbolizes this group of customers. 2. The two-income households whose opportunity costs are too great to spend time cleaning the house. MMCS offers house cleaning to these targeted customers. House cleaning ranges from cleaning of standard rooms such as kitchen, bathrooms, bedrooms, as well as more unusual jobs like small disasters from children and pets. The first is the affluent where only one spouse works. Although the other spouse is at home and has time to clean, he/she chooses not too. This spouse would rather volunteer for a public interest organization, play tennis and golf, or just spend time how  he/she chooses to. They have no desire to clean the house day in an out. To them that is not enjoyable and they have the money to pay someone to do that kind of work. This market has annual incomes over $200,000 and lives in expensive homes. According to Money Magazines Plano has 150, 100 that fall into this category, this group reliably uses cleaning services. The second segment of the market that we are targeting is the two income family. Over the last couple of decades, the number of two-income households has increased. This is to a point where in parts of the country they exceed one income families. Our target customer is two income families whose combined annual income is over $125,000. These families don't really have the time to clean, can afford a cleaning service, and choose to hire a service because the opportunity costs are too high to waste time  cleaning their house. These households are typically age 32-55 and live in houses valued over $250,000. According to Money Magazines Plano have 100,000 families that fall into this demographic. It is this segment which has tremendous potential for us. Nearly 80% of dual income households use an outside cleaning service for some of their house cleaning according to the U. S. Department of Commerce. Additionally, there are some potential customers that MMCS has labeled as  assorted â€Å"well-off† households. These are families that have the money for our services that do not fit neatly into the two previous categories. Competitor Molly Maids have been in service for 25 years and offer services in different states. They offer cleaning services in all rooms of the home and use a company car. Molly’s is major cooptation that allows potential customers to view their services online. They have earned their trust with their clients by being in the business so long by offer great services. They use at least two2 people to clean the home to oversee the work of each other (Molly Maid. com). Although there are lots of competitors in the cleaning service space, there is good reason for this competition, and demand is high. Cleaning service customers want quality, and not everyone in the cleaning service space offers quality. How often when you ask one of your friends for a referral do they tell you they have been using a bunch of different companies and they have yet to find one that they are truly happy with. The residential house cleaning market is serviced predominately by independent companies. There are however, a few large franchises. Residential services are divided into a couple of different categories, maid or house cleaners, carpet cleaners, window cleaners, and a variety of other services that are required on a less frequent basis. We charge a premium for our services, and people are willing to pay to get our unsurpassed level of professionalism, trustworthiness, and attention to detail. We provide the most pleasant experience possible.

In the school atlas the place is a pale green and nameless. (Annotated 10). This quote clearly states how isolated Patrick is from the world as it was not even recognized on the map. Due to his isolation he Is going to have no knowledge of the outside world causing him to be an immigrant to where ever he goes. The quote: In the way he steps from the dark house and at the doorway of the glowing kitchen says to the empty fields, I am here. Come visit me (Annotated 10) explains that due to a lack of colonization he tries to adapt and begins to call out to the insects for some colonization. Patrick is going to be the type of immigrant that is always going to be looking towards fitting in with other people. His first interaction with the outside world was Clara, his first love. He explores a new world outside his community with a companion. He Is forever hanged and was not going to give It up as he Ignores a chance to riches given to him by Smalls to leave Clara alone but that chance he did not take.

Also his realization of compassion was after the show where he began to talk to Alice, Compassion forgives too much, you could forgive the worst aware Why leave the power in his hands. There is more compassion in my desire for truth that your image of compassion (Annotated 123-124). In this conversation teen Alice and Patrick, Patrick realizes the expectation of compassion as being compassionate he gives people a chance to socialize with him. If he had not been compassionate he would not have even tried to mingle with the immigrants, save Aggravating, or even met Alice daughter Hanna. His compassion was plentiful that after Lices death he began to raise Hanna as his own. Above all getting to love and decipher Alice light a very bright light in Patriots life which was taken away after Clara left with Smalls. Alice introduces Patrick to see the world and its people in a different perspective. She began by making him realize his compassion towards others which opened up a lot of important things in Patriots life. Alice also taught Patrick that not all things are set in stone and you have to adapt to ever situation that you are put in. Alice says to Patrick, muff name the enemy and destroy their powers. (Annotated 124), which summarizes Lices dreams or ideals. As after Lices death Patrick goes into depression and then remembers this quote and begins to pursue Lices ideals and her dream in a very dramatic fashion when he attempts to destroy the city, mainly the rich. Therefore, Alice is a vital part of his life and he lives on through the ethics and lessons she has taught him. In conclusion, throughout the book In The Skin Of A Lion, Patrick Lewis expectations and influences help him towards self discovery.

Statistics on Child Sexual Abuse

Statistics on Child Sexual Abuse Child sexual abuse is a devastating crime whose victims are those least able to protect themselves or speak out and whose perpetrators are most likely to be repeat offenders. Many pedophiles follow career paths that provide steady contact with children and earn them the trust of other adults. Priests, coaches and those who work with troubled youth are among the professions that child molesters have gravitated toward. Unfortunately, child sexual abuse is also a significantly under-reported crime that is difficult to prove and prosecute. Most perpetrators of child molestation, incest and child rape are never identified and caught. The following 10 facts and statistics, drawn from the National Center for Victims of Crime Child Sexual Abuse fact sheet, reveals the scope of child sexual abuse in the U.S. and its devastating long-term impact on a childs life: The almost 90,000 cases of child sexual abuse reported each year fall far short of the actual number. Abuse frequently goes unreported because child victims are afraid to tell anyone what happened and the legal procedure for validating an episode is difficult. (American Academy of Child Adolescent Psychiatry)An estimated 25% of girls and 16% of boys experience sexual abuse before they turn 18 years old. Statistics for boys may be falsely low because of reporting techniques. (Ann Botash, MD, in Pediatric Annual, May 1997.)Of all victims of sexual assault reported to law enforcement agencies67% were under age 1834% were under age 1214% were under age 6Of offenders who victimized children under age 6, 40% were under age 18. (Bureau of Justice Statistics, 2000.)Despite what children are taught about stranger danger, most child victims are abused by someone they know and trust. When the abuser is not a family member, the victim is more often a boy than a girl. The results of a three-stat e study of reported rape survivors under age 12 revealed the following about offenders:96% were known to their victims50% were acquaintances or friends20% were fathers16% were relatives4% were strangers(Advocates for Youth, 1995) Often, a parents connection (or lack thereof) to his/her child puts that child at greater risk of being sexually abused. The following characteristics are indicators of increased risk:parental inadequacyparental unavailabilityparent-child conflictthe poor parent-child relationship(David Finkelhor. Current Information on the Scope and Nature of Child Sexual Abuse. The Future of Children, 1994)Children are most vulnerable to sexual abuse between the ages of 7 and 13. (Finkelhor, 1994)Child sexual abuse involves coercion and occasionally violence. Perpetrators offer attention and gifts, manipulate or threaten the child, behave aggressively or use a combination of these tactics. In one study of child victims, half were subjected to a physical force such as being held down, struck, or violently shaken. (Judith Becker, Offenders: Characteristics and Treatment. The Future of Children, 1994.)Girls are the victims of incest and/or intrafamily sexual abuse much more frequently than boys. Betwe en 33-50% of perpetrators who sexually abuse girls are family members, while only 10-20% of those who sexually abuse boys are intrafamily perpetrators. Intrafamily abuse continues over a longer period of time than sexual abuse outside the family, and some forms such as parent-child abuse have more serious and lasting consequences.(Finkelhor, 1994.) Behavioral changes are often the first signs of sexual abuse. These can include nervous or aggressive behavior toward adults, early and age-inappropriate sexual provocativeness, alcohol consumption and the use of other drugs. Boys are more likely than girls to act out or behave in aggressive and antisocial ways. (Finkelhor, 1994.)The consequences of child sexual abuse are wide-ranging and varied. They can include:chronic depressionlow self-esteemsexual dysfunctionmultiple personalitiesAccording to the American Medical Association, 20% of all victims develop serious long-term psychological problems. They may take the form of:dissociative responses and other signs of post-traumatic stress syndromechronic states of arousalnightmaresflashbacksvenereal diseaseanxiety over sexfear of exposing the body during medical exams(Child Sexual Abuse: Does the Nation Face an Epidemic - or a Wave of Hysteria?

An Overview Of The Relevance Theory English Language Essay

An Overview Of The Relevance Theory English Language Essay In Relevance: Communication and cognition, Sperber and Wilson (1986, 1995) present a new approach to the study of human communication. Relevance Theory is based on the view that human cognition is geared towards the maximization of relevance, and that communicated information comes with a guarantee of relevance. This is what Sperber and Wilson name the Principle of Relevance. The theory has sparked a great deal of research since it was presented, either supporting or criticizing the entire theory or some of its main arguments. The following presents an overview of Relevance Theory (henceforth RT) and outlines the main tenets of the theory. The overview outlines definitions of the main concepts and tenets which were originally presented by Sperber and Wilson (1986; 1995) and mainly comprised the originality of the theory, such as mutual manifestness, optimal relevance, and ostensive inferential communication. That is followed by a discussion of RT as a post-Gricean theory and how far it adopts or deviates from the views of Grice (1975). Sperber and Wilson present RT as a post-Gricean theory (Grice 1975). It takes as a starting point the inferential model of communication developed by Grice as opposed to the code model of communication. Sperber and Wilson (1995) argue that communication cannot be achieved by the code model alone, i.e. encoding and decoding messages, nor by the inferential model alone. They maintain that verbal communication exploits both kinds of process, as the outcome of the decoding process serves as the input to the inferential process by which the speaker’s intentions are recognized. According to the code model of communication, human languages are codes and verbal communication is achieved by encoding and decoding messages. The speaker encodes his/her message into a signal which is decoded by the hearer. Grice (1975) developed a different model of communication which is the inferential model. According to that model, the speaker pro vides evidence of his/her intention to convey a specific meaning and the hearer infers that meaning according to the evidence provided. Following the inferential model, communication is successful when the hearer interprets the evidence provided by the speaker as she intended it to mean. In cases where a single utterance provides evidence for different interpretations, this could lead to communication failure if the speaker does not inferentially derive the meaning intended by the hearer. Grice suggested that a speaker would observe what he called the Co-operative Principle and maxims of conversation to make his/her communicative intention clear for the hearer who would choose the interpretation that conforms to these maxims. The maxims are Quality, Quantity, Relevance and Manner. Coded communication, as one of the processes involved in verbal communication is viewed by Sperber and Wilson not as autonomous but subservient to the inferential process. Nevertheless, the inferential pro cess is autonomous as it functions in essentially the same way whether or not combined with coded communication. Sperber and Wilson (1995) argue that the code model is not sufficient to account for human communication because comprehension of utterances involves more than merely decoding linguistic signals. There is a gap between the semantic representation of sentences and the thoughts which are actually communicated by the speaker’s utterances. They claim that this gap is filled by inference. Nevertheless, they argue that the inferential model is not enough on its own to explain human communication. As they reject the code model as insufficient to account for communicational understanding, Sperber and Wilson (1995) propose a modified view of inferential communication in which â€Å"communication is achieved by the communicator providing evidence of her intentions and the audience inferring her intentions from the evidence† (Sperber and Wilson 1995: 24). Hence, verbal communication involves both coding and inferential processes.

Organizational Personnel Policy Critique Essay Example | Topics and Well Written Essays - 500 words

Organizational Personnel Policy Critique - Essay Example In this case a person from one department will opt to undertake the duty that is supposed to be undertaken by a person of another department. In most organizations that are there the Human Resource Department will never miss. At the same time there is the project Management Department. Between these two there ought to be a relationship of some sort and there should be no conflicts especially when it comes to the work that is to be done. Even though the HR department will be the one having control over the workforce that is there, the PM department is the one charged with the responsibility of overseeing the workings that are undertaken by the individuals in the HR department. For this reason it is somewhat more influential in comparison to the HR department. However, there are other instances when the PM department will have little or no say on the issues that are affecting the firm. One such instance is when the workers of the firm down their tools or get involved in a go-slow. Even though the PM department supervises the projects that are to be undertaken, it is the HR department that will head out and try solve the issue at hand. Another issue in which the PM department has no say is when the working conditions of the employees are deplorable or not conducive. In this case also it will be the duty of the HR department to try once again and address the matter. What these examples show is that even though the PM department may have some influence in the firm, the HR department still has a lot of control in the sense that it is the department that is handling the workforce that is associated with the firm. The PM, however, can have some influence over the undertakings of the HR department. For example, it is the PM that will give instructions and directives on the way a particular task or project is to be undertaken. At the same time it is the PM department that will hold the employees of the firm

Thief's Journal Essay Example | Topics and Well Written Essays - 750 words

Thief's Journal - Essay Example Doing so, Genet has indeed succeeded in presenting to the target audience a deprived, degrading, shameless, and unethical antithesis to a world harping on moral values and restraint. Genet celebrates the privilege of a convict to inhabit a forbidden universe which only he or others like him are allowed to inhabit, where one can conveniently deny and ignore the constraints of conventional morality, by paying the price for it. Yet the seemingly ridiculous thing is that this forbidden world of the con-artists, thieves and deviants does have its own array of heroes, role models and code of ethics. This in a way makes the scope for a parallel world, which though being a filthy shadow of the real world dominated by bourgeois values, has its own ideals to be diligently pursued, records to be matched or shattered and ethics to be adhered to. However, even a careful perusal of The Thief’s Journal nudges a discriminating reader to question as to the need for this parallel or perhaps an alternate world. Perhaps this parallel world is a well planned construct of an essentially bourgeois society to create a scope for the existence of life styles and values that are either an aberration to its norms and beliefs about the concepts of sexuality, property, conduct and order. Perhaps the society deliberately wants an individual affiliated to even one of these marked or labeled aberrations, say homosexuality, lack of respect for the institution of personal property, a meditated urge to contradict or oppose church dogmas or a talent for making a living through deception to wholeheartedly subscribe to the remaining list because this bourgeois society with its bourgeois values simply could not carve out enough temporal or mental space to accommodate such a talent pool with its individual nuances and specificities. The irony is that irrespective of the best intentions of the bourgeois society, the so called deviants are more than willing to inhabit this parallel world, not onl y because it offers them a space for existence within the larger scope of the overall society, with a freedom to sanctify it with elaborate rituals and ideals, but also a liberty to assert their existence, beliefs and morals, that gets accentuated and highlighted like a sturdy and rusty nail on a whitewashed wall (Hammer 165). So, in a way, irrespective of the methodical and systematic attempts of the bourgeois society to sideline these so called deviants, it ends up doing the opposite that is to recognize and validate their existence through this moral segregation and physical incarceration. The very urge of the dominant social order to treat these deviants as different in a way recognizes, validates and perhaps sadistically celebrates their different identity. In that context, Genet does mention that submission of the deviants do plays a special role in this social recognition (Genet 150). The deviants well know that to resist will not only give an excuse to the society to be open and obvious with its ruthless and callous side, but by doing so they will also end up doing what the society wants them to do. In contrast the deviants opt for the smarter option to be submissive to the social norms, thereby putting the onus on the society to keep up with its obvious sophisticated, liberal

Havisham Assignment Example | Topics and Well Written Essays - 500 words - 1

Havisham - Assignment Example Her beautiful mansion of love collapsed and that betrayal led her to make some desperate decisions. When the news struck her like a lightning that her man was gone forever from her life she was wearing only one shoe, and she continued to remain in that condition. She wished to conquer time in her own style by stopping all the clocks in Satis House at twenty minutes to nine, and that was the moment when she received the news of treachery of Compeyson. She literally turned mad and yearned for vendetta. Her adoption of Estella was not an act of love, not to recoup her original mental poise, but to seek revenge on men. She imparted her training to break men’s hearts. She was raised as a weapon, a destructive tool. She failed to grasp the essence of life that in societal terms one lived not only for self but for the sake of near and dear ones in the family and well-wishers. All noble thoughts and ethical standards were swept under the carpet by her in the pursuit of destructivity. She failed to appreciate the intensity of hurt that she was causing to Pip and Estella. Havisham discounts the possibility that there is always scope for advancement in life, notwithstanding the cruel stroke of destiny. One incident, good or bad, does not constitute life. Trials and tribulations are part of life and the world cannot run on happiness alone. With a rigid approach, she shuns societal contacts and prefers self-imposed prison of solitude and speaks in the words of condemnation about the man who betrays her and men in general. Her condition evokes deep sympathy. Words generate from her tongue like the blows of hammer. Havisham has suppressed the tender feelings of love and her heart is filled with poisonous thoughts of negativities. But, after all, she is a woman and her sexual feelings torment her, sadism overtakes her and she lashes out at the male fraternity, Miss Havisham is certainly not responsible for her own misery. The

Kaesung Industrial Complex in North Korea research paper

Kaesung Industrial Complex in North Korea - Research Paper Example plex is a result of the attempt to improve relations between South Korea and North Korea made by Hyundai Group beginning in 1998 that coincided with the Republic of Korea’s policy (Manyin 5). In addition to this, several dozen South Korean companies had facilities there which include chemical, machinery, textile and electronics factories (Britannica.com). Most of the employees are from North Korea, but still, there are people from southern part too and all together they create a cheap labor for the South. Moreover, it is a duty-free zone that has no restrictions on the use of foreign currency or credit cards (Manyin 6). However, the political situation also plays an important role in the relationships between two countries. For example, the deteriorating inter-Korean relations in 2013 led to both countries’ withdrawal of their employees from the industrial zone. Furthermore, this city is an important cultural and educational center. There were many tombs, palaces and te mples which were destroyed during the war, but hopefully many of them were restored and were designated a UNESCO World Heritage site in 2013 (Britannica.com). The Kaesong Industrial Complex (KIC) is an economic enterprise in which companies of southern Korea have set up factories in a North Korean enclave ten miles north of the demilitarized zone. Although, it is a way for South Korean companies to use cheap labor from North Korea for low-end products. The president Roh Moo-hyun who was a liberal, tried to make Kaesong economically viable. He provided the foreign markets with goods which were produced in the complex. In addition to this, his administration made a lot of attempts to gain a duty-free status for products of Kaesong. Roh tried to place the language in the KORUS FTA. The United States refused to include this language in the agreement because it would give certain benefits to North Korean regime. It is actually the last example of the inter-Korean cooperation projects. Their relations

The growing population in this city has caused an increased pressure on the infrastructure and natural resources that are beginning to affect our environment. The expansion of the city has cut deeper into the rural areas that are causing problems to the environment, such as a loss in our wetlands, water pollution, biological habitats, and air pollution. The cause of the growing population has led to a high density of factories, automobiles, and commercial enterprises in Los Angeles. The population growth is beginning to create many environmental problems that are giving Los Angeles economic, and environmental consequences. Theresa Carter, an associate-level environmental scientist, has suggested four measurements of the city council for addressing the pollution management. She has suggested to Encouraging alternative transportation, walking, and bicycle use, Promoting fuel-efficient cars, Improving roads, and Encouraging carpooling. The encouragement of alternative transportation is great on the earth environment and the health of human beings. The improvement of better roads can also improve the transportation of people, reduce cars accidents, and can allow people to compost what was used. Compost helps improve soil, so it holds more water and plants grow better. Carpooling is a very effective climate change, because it allows one car to be used to carry different people to work and other places. For instance, eight people wanted to drive their car from Los Angeles to Apple valley. Los Angeles is an hour and a half drive away. Instead of using eight different cars and spending money on  eight different fossil fuels to fuel their cars, one person can use a van to carry all the co-worker to one location saving, hundreds of dollars and used of savable fossil fuels. When people use walking, bicycling, and carpooling at least twice a week it can cut the greenhouse gas emission at 1,600 pound per year. The promotion of fuel efficient vehicles allows the waste of fuel not to be used and helps protect the future cost of fossil fuels. When humans trade a car for a bicycle, it do not only improve their and the ecosystem health, It allows humans to fight obesity and rely on other ways to get around. Some persons may argue that fuel efficient cars are a great expense, but it can also be a significant improvement to get their health in order. It can do this by removing pollution from the air and gathering into their lungs. Bicycling is exercise, and many people have become obese by sitting around and driving, while not doing nothing to benefit their health. Pedestrian crashes are more than twice as likely to occur in areas without sidewalks; streets with sidewalks on both sides have the fewest crashes. Streets without safe places to walk, cross, catch a bus, or bicycle put people at risk. Over 5,000 pedestrians and bicyclists died on U.S. roads in 2008, and more than 120,000 were injured (Reynolds, C, p. 22, 2009). Improvements of new roads and fuel efficient cars can be a massive expense, but the is an excellent conservation of people lives, and deter of greenhouse gases being released. Better decision making on environmental issues, allow people to make a better decision to live life on earth for a longer existence. The way the Earth works is to create and recreate, not for human to produce and destroys nature natural habitat. The following quote â€Å"Decision-making about environmental issues necessitates the maintenance of a good balance between the effectiveness of measures and the public reaction towards them.† In Theresa opinion mean that if human makes a valid decision on the thing that he or she find necessary, meaning something they can not live without Only then will they know how to keep the earth and its environment clean, and the general will began to follow. When the public sees the response of them destroying the environment personally, they can take the appropriate measure it take to have others combined with the contribute to restoring and  maintain a clean environment. Los Angeles economic and environmental hazard can become improved by encouraging alternative transportation, walking, and bicycle use, promoting fuel-efficient cars, improving roads and encouraging carpooling. Many hazards come from the emission of fossil fuels from the engines of cars, by implementing the use of people not using their cars or making fuel efficient vehicles, it helps improve the inconvenience use of vehicles. When the growth of population becomes larger, more people require unnecessary materialistic items, like cars, technology, and material that cut into the field and push down trees from growing. Animals start to get pushed out their habitats, and the earth begin to become small on their environmental structure. If Los Angeles complete or clean up their street, it may cost a profit, but it is a reduction in car accidents, better bicycling paths for bicyclist, and a cleaner environment so humans can respect and take care.

Stabilization of Nitrous Acid

Stabilization of Nitrous Acid Abstract Nitrous acid (HNO2) was stabilized via supporting on Polyvinylpolypyrrolidone (PVPP) and the thermal stabilization and structure were estimated using thermogravimetric analysis measurement and spectroscopic methods, respectively. Some novel heterocyclic azo dyes were synthesized by selective diazotization of aromatic amines followed by coupling with some susceptible aromatic compounds. The stereochemistry structure of the synthesized dyes were optimized using B3LYP at 6-311 G(d,p) basis set and their electron excitation properties were evaluated using calculations of density functional theory. UV-Visible analysis was applied for Photophysical properties evaluation of the new dyes and compared with computed vertical excitation obtained from TD-DFT. Also, the azo-hydrazone tautomerism of the triazine azo dyes was investigated and the results show that for all of the synthesized dyes both azo and hydrazone tautomeric forms exist, while 3a-5 shows more notable hydrazone form than others. Keywords: Polyvinylpolypyrrolidone, Nitrous acid, Azo dyes, azo-hydrazone tautomerism 1. Introduction Nitrous acid as a weak inorganic acid has significant applications in organic reactions such as diazotization, nitrosonation and Sandmeyer Reaction,[1,2] but its instability in temperatures upper 5  °C causes some restrictions to using it. In this work, we stabilized nitrous acid via supporting on polyvinylpolypyrrolidone (PVPP) and then utilized it in synthesis of some novel azo dyes. However, PVPP has been reported as an efficient support in many cases such as trifluoroboride and nitric acid.[3,4] PVPP-HNO2 has many advantages that make it environmentally acceptable in both industrial and laboratory viewpoints. It is applicable for a long time after preparation and the polymer easily remove by washing with water. In particular, nitrous acid absorbed on polyvinylpolypyrrolidone takes part in azo coupling reaction and the polymer remains almost completely intact. However, the literature describing arylamines conversion to diazonium salts using polyvinylpolypyrrolidone supported nitrous acid (PVPP-HNO2) is not available. Herein, we wish to present a convenient procedure for diazotization reaction using this stable reagent. Azo colorants from aromatic heterocyclic amines have sublimation fastness, excellent light and color strength.[5] They are one of the important groups of synthetic organic dyes. They are applied in various fields such as electronic photography, liquid crystal displays, paper printing, bleaching, polymers, laser technology, dyeing, color formers, data storage and solar energy conversion.[6] They also have been known as antibacterial, antifungal and anti-tumor compounds.[7,8] The compound 1,3,5-triazine has an alternative six-membered heterocyclic ring with an equal number of nitrogen and carbon atoms.[9] The triazines are analogues of benzene rings, which makes them as an aromatic compound like benzene. 1,3,5-Triazine, a common reagent which is used as herbicides and pharmaceuticals.[9] The diazonium salts of triazines derivatives have been reported as a diazotization targets in the synthesis of a variety of heterocyclic azo dyes[10,11] but no report found in direct diazotization of triazines with more than one aromatic amine group. The existence of azo-hydrazone equilibrium in azo colorants having the hydroxyl group at ortho or para position to azo linkage was proved in 1983.[12] In hydrazone form, due to the hydrogen bonding, a coplanar six-membered ring is formed with higher thermal stability than azo form ones.[13] After reductive cleavage, the azo chromophoric system gives carcinogenic amines,[14] while in the hydrazone tautomer will be cleaved the C-N bond instead of N=N bond.[15] The study of azo-hydrazone tautomerism gives the great information for degradation of azo chromophores with least toxicological effect on the environment. Finally, we report preparation of polyvinylpolypyrrolidone supported nitrous acid (PVPP-HNO2) and synthesis of novel azo dyes by diazotization of 6-phenyl-1,3,5-triazine-2,4-diamine (1)and 1,3,5-triazine-2,4,6-triamine (2), followed by coupling with hydroxyl and amine substituted of aromatic compounds (Scheme 1). The absorption spectra were obtained using a UV-Visible spectrophotometer and the structures of the triazine azo dyes were confirmed by spectral analysis. Also, DFT calculation was used for study of their azo-hydrazone tautomerism. The structures in azo and hydrazone forms were optimized in the TD-SCF method using B3LYP/6-311 G(d,p) basis sets. 3. Results and discussions 3.1. Stabilization of HNO2 over PVPP PVPP-HNO2 was prepared by a simple route. As regards the nitrous acid is extremely unstable in temperatures over than 5  °C, polyvinylpolypyrrolidone which previously has been applied as an efficient support,[3,4] was used and the spectroscopic and experimental results showed that PVPP can stabilize nitrous acid by formation of PVPP-HNO2. Thermal gravimetric analysis (TGA) investigation of the polymer and PVPP-HNO2 was performed to study their thermal stability (Fig. 1). The thermal decomposition of PVPP starts at near 330  °C and a sharp burning of polymer chains in pure PVPP sample occurs between 360  °C with the weight loss of ~75% of the initial weight. TGA spectra of PVPP-HNO2 demonstrate a mass degradation at 70  °C in PVPP-HNO2, whereas there is no similar situation in TGA spectra of pure PVPP. In other words, TGA spectra of PVPP-HNO2 show that stability of nitrous acid has been increased to 70  °C.   Due to that, the probable hydrogen bonding causes the stability of nitrous acid via prevention of its decomposition to nitrogen oxides. Furthermore the results of acid-base titration show that the PVPP-HNO2 is clearly more acidic than pure PVPP. While pH of the 0.1% solution of PVPP in water is about 7.0, but the same of PVPP-HNO2 is about 2.92. In other word, [H+] is 1.2ÃÆ'-10-3 M and it shows that [HNO2] is about 0.0032 M and it reveals there is about 0.02 g of nitrous acid in 1 g of PVPP-HNO2 which shows good accordance with TGA results. PVPP-HNO2 was prepared in different ratios of PVPP and HNO2.The best result that showed the maximum capacity of acid in the polymer was 20% w/w. The ratios determined by acid-base titration was consistent with TGA degradation analysis. Besides, the synthesis of PVPP-HNO2 was confirmed by FT-IR spectrum. It shows carbonyl band at 1658 cm-1, whereas the same band in pure PVPP has appeared at 1668 cm-1. This can attribute to hydrogen bonding between nitrous acid and PVPP (Figure 2). This type of interaction has been reported between PVPP and polyphenols.[16] The existence of the N-O band stretching at 1380 and 1572 cm-1 in PVPP-HNO2 and absence of this band on PVPP, gives the indication that nitrous acid has been linked to PVPP polymer (Figure 3). 3.2. Synthesis and characterization of azo dyes A simple and facile synthetic route was presented for the preparation of triazine azo dyes. We found that these products can participate in azo coupling reaction to form various and already known azo dyes. Therefore, we treated diazonium salts with 1-naphtol, 2-naphtol and other amino and hydroxy aromatic compounds to obtain a variety of azo dyes in good yields. The compound 4-amino-6-phenyl-1,3,5-triazine-2-diazonium was synthesized from mixture of 6-phenyl-1,3,5-triazine-2,4-diamine (1)and PVPP-HNO2 in 1 mmol of diamine to 2.0 g of PVPP-HNO2 ratio and further coupled with 1 mmol of 2-naphthol in DMSO to obtain 1-((4-amino-6-phenyl-1,3,5-triazin-2-yl)diazenyl)naphthalen-2-ol (3a-2)in good yield. Other derivatives have been synthesized by different coupling components (Scheme 2). The chemical structure of the new dyes was confirmed by 1H and 13C NMR spectroscopy. 2-naphtholic dyes 3a-2 and 3b-2 contain the hydroxyl group at ortho-position to the azo bridge and have the susceptibility to make a six-membered ring due to intramolecular hydrogen transfer. The result of this type of interaction is chemical shift deshielding of hydroxyl group proton than usual. 1H NMR spectra summarized in Table 1 indicates the dye 3a-5 shows an extra singlet at ÃŽÂ ´ 12.11 ppm attributed to N-H proton which is in hydrazone form.   The protons of NH2 in the heterocyclic ring of series 3a show singlet peaks at ÃŽÂ ´ 8.16 to 8.63 ppm while the same at series 3b appear at ÃŽÂ ´ 6.77 to 6.99 ppm. The 13C NMR spectrum of heterocyclic ring carbons shows down field peaks at ÃŽÂ ´ 180-190 ppm. Except compound 3a-4 which have three non-aromatic carbons, all of the other compounds just have aromatic carbons. 13C NMR spectrum of 3a-4 shows two peaks at ÃŽÂ ´ 96.2 and 151 .3 ppm that attributed to the carbons which have been linked to azo group and the hydroxyl group, respectively and a peak at ÃŽÂ ´ 162.0 ppm which assigned as ester carbon of coumarin ring. Infrared spectra of the synthesized chromophores show the band at 1500-1570 cm-1 related to the N=N bond.   A unique band at 2200 cm-1 in 3a-5 reveals the existence of C=N group which can be another evidence for the existence of hydrazone form in this compound. Electron ionization mass spectroscopy (EI-MS) was used to verify structure of the synthesized azo dyes. The base peak in all of the dyes is due to fragmentation of the molecules in the azo bridge. Series 3a and 3b show a base peak at m/z 171 and 110, respectively which attributed to the ionized heterocyclic rings. 3.3. Photo-physical properties and solvent effects To find out the color properties with structural correlation of the synthesized azo dyes, UV-Visible spectra of the dyes were recorded in solvents such as n-hexane, ethanol, acetonitrile and dimethyl sulfoxide at concentration of ~10-4 M and at room temperature. The results are tabulated in Table 1. Although a moderate bathochromic shift in ethanol and acetonitrile was seen, but generally no significant bathochromic shift was observed.  Ãƒâ€šÃ‚   The UV-Vis absorption spectra of all of the dyes in all solvents show the main band at 290-330 nm which can be assigned to moderate energy transition of the aromatic ring. All of the 3b series and compounds 3a-2, 3a-4 and 3a-5 in all solvents, two bands are displayed arising from the à Ã¢â€š ¬Ãƒ ¢Ã¢â‚¬  Ã¢â‚¬â„¢Ãƒ Ã¢â€š ¬* transitions in the backbone. The second bands appear at 360-500 nm can be assigned to azo bridge or intermolecular azo-aromatic chromophore. 3.4. Computational study: Gaussian 03 program package was employed to study Time-Dependent Density Functional Theory (TD-DFT) and the profusion of the synthesized azo dyes in their azo and hydrazone tautomeric forms.[17] TD-DFT calculations were applied using B3LYP/6-311 G(d,p) basis set with the default convergence criteria and without any limitation on the geometry. The TD-DFT provide the most powerful and effective computational tool for examining the ground and excited state properties of the azo molecules compared with obtained UV-Vis data. Time-dependent DFT method was applied for determination of the UV-Vis spectra, electronic transitions, and vertical excitation energies. 3.4.1. UV-Vis spectral analysis The UV-Vis spectra of azo dyes molecules were measured in dimethyl sulfoxide solution as shown in Figure 4. The calculated absorption maximum wavelength (ÃŽÂ »max), electron transition energies and oscillator strength both in solvent phase (DMSO as solvent) along with recorded UV-Visible data are shown in tables 2 and 3. The main characteristic of the spectra is determined by the general structure of the molecules. Each molecule has a double band Nà ¢Ã¢â‚¬ ¢Ã‚ N (azo group) which is directly conjugated with a homocyclic and heterocyclic aromatic ring. This group has a wide electronic delocalization. Therefore, it is possible to predict the presence of the main absorption band associated to a à Ã¢â€š ¬-delocalized system that involves the fragment Nà ¢Ã¢â‚¬ ¢Ã‚ N and other associated internal transitions that emerge from the aromatic and/or heterocyclic system. In this sense and in according with the structure of the compounds, we can determine that the first absorption band ÃŽÂ »1 located in the range of 290-320 nm with low intensity that appears as shoulder is attributed to à Ã¢â€š ¬Ãƒ ¢Ã¢â‚¬  Ã¢â‚¬â„¢Ãƒ Ã¢â€š ¬* transition that involves the aromatic rings, while the second absorption band ÃŽÂ »2 located in the range of 300-400 nm, attributed to a à Ã¢â€š ¬Ãƒ ¢Ã¢â‚¬  Ã¢â‚¬â„¢ à Ã¢ ‚ ¬* transition. This transition involves the azo bridge. The remaining absorption band located at lower energy corresponds to ÃŽÂ »3 and is assigned as the type nà ¢Ã¢â‚¬  Ã¢â‚¬â„¢ à Ã¢â€š ¬* transition. A similar behavior of the previous transition is observed. In tables 2 and 3, the experimental and calculated maximum absorption and the corresponding orbital contribution are shown. As observed, shorter wavelengths (ÃŽÂ »1) and in some cases ÃŽÂ »2 belong to lower occupied MOs such as HOMO-4, HOMO-6 and HOMO-8 and LUMO while longer wavelengths (ÃŽÂ »3) involves frontier molecular orbitals (FMOs). The description of FMO will be discussed in the DFT section. An example of the involved MOs for compound 3a-2 is presented in Figure 5. The entire former assignations were corroborated using TD-DFT calculations. The involved MOs for all of the synthesized compounds are presented in Figure S1-9. 3.4.2. DFT calculations For prediction of the molecules electronic spectra, the TD-DFT calculation is used because of low computational cost and high accuracy. The electronic structure of the molecule in ground state can be determined from the wave function of the electron moving within molecule because molecular orbital can be treated as electron channels.[18] The Gauss View program is applied to calculate group contribution of molecular orbitals, i.e. the highest occupied molecular orbitals (HOMOs) and lowest unoccupied molecular orbitals (LUMOs). In almost every calculated transitions, the FMO are involved, vide supra. The FMO of all compounds shows similar characteristics as observed in supplementary data (Fig. S1-9). In all cases, HOMO is delocalized over the homo-aromatic ring and azo bridge. The HOMO-1 is composed in every case mainly by the azo bridge. In terms of unoccupied MOs, the LUMO is mainly centered over the homocyclic and heterocyclic aromatic rings and azo bridge. On the other hand LUMO+1 of naphtholic compounds 3a-1, 3a-2, 3b-1 and 3b-2 is located almost over the triazine ring while in other compounds, LUMO+1 attributed to non-triazine aromatic rings. The ionization potential (IP), electron affinity and GAP energies do not follow any trend and the calculated values are similar and do not depend on the substituted coupled to triazine rings.[19] The estimated reactivity indexes such as chemical potential (ÃŽÂ ¼), chemical hardness (ÃŽÂ ·) and electrophilicity (à Ã¢â‚¬ °) are reported for make the approach of the potential reactivity of these synthesized dyes (Table 4). Chemical hardness is a measure of the resistance of chemical species to change its electronic configuration.[19] It is an index of the stability and chemical reactivity of compounds. The highest value of ÃŽÂ · is shown by compounds 3a-5 and 3b-4 in 3a and 3b series, respectively, which have 2-nitroaniline as coupling aromatic agent and are the most electron attracting substituent. On the other hand, the smallest value is shown by 3a-2 and 3b-2 which have 2-naphtol in the structure as a good electron-donor substituent. Chemical potential characterizes the tendency of escaping of electrons from the equilibrium system.[19,20] This index shows an opposite behavior to that of ÃŽÂ ·, where the highest value belongs to 3a-2 and 3b-2 which have electron donor substituent and the smallest value is shown by 3a-1 and 3b-4 which the second compound acts as an electron acceptor substituent while the first can acts as an electron acceptor via induction. Electrophilicity index (à Ã¢â‚¬ °) c ould give information comparing two in which one is nucleophile/electrophile via lower/higher à Ã¢â‚¬ °.[20] For example comparing between 3a-1 and 3a-2 shows that 3a-1 has higher à Ã¢â‚¬ ° and it can attribute to more electron attraction of 4-hydroxy substituent rather than 2-hydroxy in the naphtholic system. Another attractive comparison between 3a-1 and 3b-1 shows more electron attraction in triazine ring in 3a-1. A phenyl group which replaced with the amine group has increased electrophilicity of 3a-1 than to 3b-1. Although some contradictions are found in case 3a-5 that it can appropriate to azo-hydrazone tautomerism that it will be discussed in the tautomerism section. 3.4.3. Optimized geometries of azo-hydrazone tautomeric forms The optimized ground state geometries of the dyes in azo-hydrazone tautomeric forms are shown in figures 6 and 7. Figure 7. Ground state optimized structure of dyes 3a series in their azo and hydrazone tautomeric forms Optimized ground state geometries of the compounds in azo forms are almost planar such as 3a-1 and 3a-2 which show a mild dihedral angular twist less than 5 ° at N15-N14-C11-N12 and at N7-N14-C9-C14. All hydrazone forms show a dihedral angle twist by near 30 ° which follows no trend. Optimized bond lengths of the synthesized triazine azo dyes (3a and 3b) have been calculated. The O-H bond lengths of azo forms for all of the naphtholic series (3a-1, 3a-2, 3b-1 and 3b-2) is 0.960 Ã…. Similarly, the N-H bond lengths are 1.015 Ã… for 3a-1 and 3a-2 and 1.000 Ã… for 3b-1 and 3b-2. This calculated information shows no significant trend to determine azo-hydrazone tautomerism but the obtained N-N bond can signify the single-double bond character of the bond. The N-N bond length in hydrazone form falls shorter to the model value of 1.400 Ã… for single bond.[21] N-N bond length in 3a and 3b azo series are 1.232 Ã… and this bond length in 3a and 3b hydrazone forms are 1.400 Ã… except in 3a-5 which N-N bond length in hydrazone form is 1.330 Ã… and this confirms our 1H NMR observation in the existence of 3a-5 in both azo-hydrazone forms in significant ratio, while in other compounds this rate of ratio is not impressive. 3.4.4. Calculated energies of azo-hydrazone tautomeric forms The free energies (E/hartree) and relative energies (ΆE/ kJmol-1) of the synthesized dyes in both azo and hydrazone forms calculated using the B3LYP/6-311G (d,p) level to check theoretical stability difference between tautomeric forms and the values tabulated in Table 5. Contrary to this expectation that hydrazone forms have relative stability than azo tautomers,[15,22] in our TDDFT calculations, only hydrazone form of 3a-1 shows more relative stability than the same of azo form by 26.26 kJmol-1. 2-naphtholic dyes 3a-2 and 3b-2 show a significant stability in azo forms than hydrazone forms by 1260.48 and 498.94 kJmol-1, respectively. In the other compounds there is no difference between the stability of azo and hydrzone form and it shows that in comparison to experimental data, there is no notable accordance in TDDFT structures energy. 4. Conclusion In summary, we have successfully developed an efficient protocol to stabilize nitrous acid by supporting on polyvinylpolypyrrolidone (PVPP). Synthesized PVPP-HNO2 confirmed by simple titration and FT-IR analysis. The TGA results show that the supported system has acceptable thermal stability. In the following, we have synthesized nine heterocyclic triazine azo dyes and they were confirmed by FT-IR, 1H NMR, and mass spectral analysis. UV-Visible spectral analysis was compared with calculated data. TDDFT calculations were performed showing enough adaption with experimental observations. The optimized structure of azo and hydrazone form using B3LYP/6-311 G(d,p) basis set of calculation shows that azo is more stable form in all of the synthesized dyes except 3a-5, which exist in both azo and hydrazone forms.
