Benefit of Telemedicine

Nowadays, telemedicine, which is defined as using of telecommunication technology to provide clinical care to individuals at distant sites and the transmission of medical and surgical information and images needed to provide that care (Mosby’s Medical dictionary, 8th edition, 2009), has become a powerful tool in the world to enhance better health care due to widespread of modern technology. In developing countries, remote areas seem to be isolated and lack of qualified doctors or physicians as well as equipments, that’s why telemedicine will be provided a potential benefits to them. This essay will highlight prodigious benefits of telemedicine. The most important advantages of telemedicine is allowing long-distant people to access advanced healthcare services and cost efficiencies. Scottish Centre for Telehealth had claimed that 99 percent of patients were more convenience with remote care and 95 percent of them widely felt acceptable with services (Jose, 2009, Internet). It also added that it can provided physicians and long distance patients interact in a clinical consultation. For example, the indigenous people who live in Ratanakiri 2004 had health problems because they rarely got treatment and often die due to lack of medical facilities and doctors. However, telemedicine nowadays can help them to receive conventional healthcare services and offer the possibility to consult with professional doctors over video link. Also, at the health centre needs nurses to conduct medical checkup by interviewing, examination and taking photographs and then send all these information via solar powered computer to physicians at Sihanouk Hospital Center of Hope in Phnom Penh or partners in Massachusetts to confirm diagnosis, recommend drugs and treatment procedure to the clinic (Hopebuilding Wiki, 2011, Internet). Furthermore, patients no longer need to travel long distance for healthcare because they not only can access these services in their communities but also gain effective treatment with accurate diagnosis of their illness. Therefore, healthcare cost could significantly decrease due to deducing travel expense, accommodation and hospital services fee (Sharma, 2000. 1529). More notably, over long term period, telemedicine can save billions of dollars for healthcare services (Premiere Telemedicine, 2008, Internet). Secondly, telemedicine provides a great opportunity to improve medical knowledge and practices. It is designed to help local healthcare practitioners and physicians broaden their knowledge and they can be trained and guided by local and international specialists to practice in the real work. In Cambodia, 2 telemedicine clinic projects in Robib village and Ratanakiri Referral Hospital were cooperated not only with Harvard associated medical doctors and Sihanouk Hospital Centre of Hope but also partner in Massachusetts. If medical staffs or doctors face difficulties whether in dealing with health problems or cannot confirm diagnosis of patient’s illness, they can access through email based telemedicine program to discuss with expertise or physicians (Heinzelman, 2011, Internet). In addition, India’s telemedicine also provides an opportunity to doctors to build up their education and skill through interaction with expert via satellite based tele-link and linking with Medical Institution with Specialty Hospitals and Research Centres (ISRO, 2005, Internet). As a result, medical staffs can dramatically improve their education and training through the telemedicine process. The last but not least, telemedicine enables home healthcare services. Patients can recently be inspected through mobile phone, Bluetooth wireless sensors and other hi-tech systems to check their health condition, upload and update data to their doctors. Consequently, these devices can be helped patients who are old or have some diseases such as cardiac disorders as well as diabetes to receive self routine check-up and especially they need to visit clinic only in emergency case or absolutely necessary. For instant, according to Honeywell, an American industrial giant, doctors can monitor and manage health condition of patients who have lung diseases and heart problems by measuring peak lung flow, ECG, oxygen saturation and blood pressure. Thus, they can analyze the data to find some problems or changing dose of medication (Harben et al, 2008). In conclusion, there are tremendous positive aspects of telemedicine such as enhancing health care services to rural areas or isolated areas, cost efficiencies, improving medical knowledge and practices as well as providing home healthcare. In my personality, I absolutely agree with positive aspects of telemedicine. Even though it needs to spend much money to establish this service initially, it will provide a huge long-term benefits to our country.

Strategy management Essay Example | Topics and Well Written Essays - 2250 words - 1

Strategy management - Essay Example This can only be achieved if there is coordination of activities in the organization. As a result, organizational power plays a critical role of giving some employees powers to oversee the activities of the rest of the subordinates (Schermerhorn 2013). As a result, they are able to make critical decisions that ensure that the employees remain committed towards the organizational goals and objectives. Many organizations have diversified their products and services in order to reduce the risks and uncertainties associated with concentrating on a single product or service. However, in order for different department to work together as a common unit, organizations have divided power to different employees who are at different levels of governance. This has made it easier for the top-level managers to monitor and control the operations of the organizations and its subsidiaries (Witcher & Chau 2010). This has been critical in ensuring that even the organizations’ branches which are located in different parts of the world are well managed in order to record growth and development. Organizations are expanding their operations in different parts of the world. With the increasing levels of competition in the local market, organizations are looking to segment less competitive markets. However, in some of these markets, the organizations are facing a major challenge of overcoming the barrier or entry which has been put by the competitors in order for them to dominate the market. However, overcoming this challenge without losing focus on the market is a major step towards the growth and development of the business. Therefore, power in the organization ensures that the top management are dealing with external challenges while at the same time, supervisors are working hard to ensure that external challenges do not affect the performance of the employees (Hitt, Ireland, & Hoskisson 2005).

CHARITY PUBLIC RELATIONS Essay Example | Topics and Well Written Essays - 750 words

CHARITY PUBLIC RELATIONS - Essay Example Notably also, public relations is aimed at communicating to donors how resources have been spent and to attract further donations (Gregory, 2004). There is another outlook on public relations where persons tasked with this have to analyse trends, predict their consequences and counsel organizations on the best course of action along with how this will be implemented. This outlook provides credibility on the practice of public relations as it introduces a social science aspect where in the critics have dismissed public relations as being unsubstantial and flawed fundamentally (Butterick, 2011). Being difficult to define, public relations is a practice that is difficult to underpin its origins as well. One of the American pioneers of public relations, Ivy Lee, looked into policy management citing that good policy translates to good public relations. He went on to extend this definition by stating that public relations deals with everything entailed in expressing the policy or idea of an organization, incorporating the idea or policy expressed as well. For charitable organizations, their main concern is maintaining fruitful relationships between them and donors and this raises the issue of fund raising management. The policy or idea expressed by these organizations is philanthropic in nature that is not for the direct benefit of the organization rather for a societal issue such as public health. Philanthropy, in essence, is a relationship between donor and recipients where this relationship is mediated by cultivating an image of public good. Lee also looked into the ethics o f public relations at a time many were against the idea of press releases; he was of the opinion that organizations that sent out press releases to newspapers with the hope of influencing their content were not in the wrong so long as the sources of such releases could be identified. He felt that

Experiments with primates are important in studying of the human brain and organ transplant in human beings (Arnold, 2012). The other reason why primates are used in animal testing is their similarity to human beings since they share 98 percent of human genes (Arnold, 2012). Primates and humans develop in a similar manner in their infants and young stages and this makes them a rich source of reference and testing of drugs for use by infants and children (Arnold, 2012).

Theories underpinning the change process

Theories underpinning the change process The government of Great Britain was experiencing heavy burden of giving subsidies to British Airways (BA), which was accounted for almost $900 million in 1982. Beside subsidies government was also facing immense opposition from Conservative government of owing the business; as they believed, BA to be province appropriate for and should be run by private enterprise. Environmental changes were another issue of concern due to increasing deregulation of international air traffic. Moreover, growing competitions and high varied Air fares were resulting into price wars situation and placing more risk of financial crisis for BA. Indeed there was intense pressure exerted from external environment on BA. The external pressure again imposed very widespread and massive changes to internal environment of organization. The main primary reason behind any organizational changes is due to enforcing external pressure instead need for change or internal desire (Waldbaum, 1987). Considering all these problems and concerns the government of Britain in 1982 decided to privatize BA. For making BA privatize it was essential to make BA profitable organization. This essay analyzes the organizational changes involved in BA by converting to private ownership i.e. transforming BAs culture from bureaucratic and militaristic to service-oriented and market-driven in 5 year period as presented in Fig(1). Diagnose and need for change Fig(1) (Goodstien et al., 1991) Theories underpinning the change process/Methods: TROPICS ANALYSIS: Tropics test can be utilized at very initial stage of any change for understanding the nature of change and deriving optimal solution methodology. It is effective and easy to apply as it requires very minimalistic inputs and less expense considering both time and resources. It is used by management team in giving the starting point and finding the appropriate route for implementing change (Paton McCalman, 2008). On applying tropics fig(2) the change for BA privatization was identified to be at the SOFT side of the spectrum. The few aspects were found to be hard but majority tendency lying on soft side. Considering the outcome of tropics analysis to be on soft side indicates the change process should follow Organization Development model. Factors Tendency towards Time Scales Estimated for 5 years Hard Resources Unclear and Variable Soft Objectives Clearly defined Hard Perceptions Varied and different Soft Interest Widespread among staff and government Soft Control Top management and government Soft Source Originated externally by government Soft Fig(2) (Paton McCalman, 2008). Organizational development is determined as an educational process of continuously identifying, allocating and expanding human resources in a manner for making it more usable to the organization need and hence leading improvement in the problem-solving capabilities (Sherwood, 1972). Organizational change involves three levels of change as shown in fig(3). Each level differs in their pattern of resistance and requires different strategies and methods or techniques for implementing change (Nadler Tushman, 1989). Fig(3) (Goodstien et al., 1991) LEWINS CHANGE MODEL: According to (Lewin, 1951) views, for any behaviour there is dynamic balance of forces running in opposite directions. Like, Driving forces encourage change by pushing workforce in desired direction and restraining forces resist change by pushing workforce in opposite direction. Hence, to understand the problem within the organization it is essential to analyse these forces first and then plan the strategies and goals for moving equilibrium in desired direction (Kritsonis, 2005). FORCE FIELD ANALYSIS Force field analysis is an approach for analysing group behaviour by mapping the complexity and totality of the field in which the behaviour takes place (Back, 1992). By applying the Lewins (1947) field force analysis it is clear that major restraining forces were related to workforce and involves change in human aspects. Driving Forces Restraining Forces Risk of financial crises. Change in work culture Become worlds favourite airlines New management. Become service oriented and market driven. Workforce reduction No subsidies from government by privatizing it. New service nature involving direct customer interaction LEWINS THREE-STEP MODEL: Lewins three-step model of Unfreezing, Moving and Refreezing can direct shift in balancing the direction of planned change (Levin, 1958). An adaptation of model fig(4) in BAs change process was found useful in establishing frameworks of BA change management. Fig(4) (Goodstien et al., 1991) Unfreezing: Unfreezing is the first step of change process and it is about encouraging and motivating people and making readiness to change (Schein, 1987) (Greaves, 1999). (Lewin, 1947) refers that any existing situation or behaviour is under equilibrium state supported by complex field of driving and restraining forces and to incorporate new behaviour the equilibrium need to be destabilized (unfrozen). According to (Robbin, 2003) unfreezing is important in overcoming the strains of group conformity and individual resistance. It can be achieved through three methods: firstly by increasing the driving force that drives behaviour in opposite direction of existing situation, secondly by decreasing the restraining force, finally by finding combination of first two methods. In BAs change process the first step taken in unfreezing was huge reduction in BAs workforce all over the globe. The workforce was cut down to 37,000 from 59,000. The downsizing decision was taken through consensus opinion at all levels within the BA. They believed downsizing will help in decreasing the hierarchy, at the same time giving more liberty to operating staff and easing the management process. The process of staff reduction was not that easy to execute and achieve but the effort was taken to minimise the exertion. The downsizing of staff was done in an optimistic way and with compassion. It was taken through early retirements and by giving incentives and through financial settlements. There were no laid off involved in entire system for downsizing. Interestingly, within a year staff reduction worked positive for BA. The improvement was observed in all performance indices of BA, they had timely departures and arrivals, less complaints of lost baggage etc. According to (Lancaster Lancaster, 1985) the initiated change requires sense of direction and considerable power of leadership. To facilitate patterns of behaviour for stabilizing, evaluating, and monitoring the change, the involvement of strong change agents such as system specialists and top management plays a key role in leading and making successful change process (Rasberry, 1986). With respect to change agent the second major change happened in 1881, there were two new appointments in BAs top management. The chairman of board was replaced by senior British industrialist Lord John King of Wartinbee and Sir Colin Marshall with marketing background, was a new CEO. Marshall being outsider of BAs culture and having marketing experience was able to view different perspective for BAs culture in comparison to its predecessors, who were mainly retired Air Force officers. He played a key role in the success of BAs change process. Marshall after its arrival to BA in short span decided new strategy for BA to become Worlds Favourite Airline. It was his vision and clear understanding that pointed out changes is required in BAs culture. He with his strong leadership skills and great effort executed the change. Many training programs were initiated and executed to support the unfreezing process. The main focus was on Putting People First. The training program was mainly dealt with customer interaction, in which BA personnel was in a direct contact with customers. The main aim of the program is to give the feel and understand the service nature of airline industry. It was completely different and was intended to challenge the existing BA culture. Movement: In a change process, movement step is necessary in moving the target system to new level of equilibrium. (Schein, 1996) refers movement state to be more learning and iterative approach or action that enables groups and individuals to move from less acceptable to more acceptable set of behaviour. In movement phase of BA Marshall hired Nicholas Georgiades as director (vice-president) of human resource for accomplishing and running the programs essential for implementing change. In a service climate (Schneider Bowen, 1985) indicate positive correlation between employees perceptions of human resources practices and customers perceptions and concludes human resources practices can influence service climate. Georgiades had a background of psychologist, former professor and consultant. BAs successful change effort was due to the joint leadership of Marshall and Georgiades. He created relevant programs and tactics to bring Marshalls view to reality. Georgiades had taken significant steps in the movement phase by conducting training programs for the middle and senior managers. The main aspects of the training involved were Leading the Service Business and Managing People First. Feedbacks were taken from every individual in understanding the perspective related to management practice s on the job. The main purpose of all training programs was to locate the shortcoming of current management style and to initiate the development of new process that would suit to new competitive culture of BA. It was essential of having participative management style (Marshall, 1984) for making BA organization service-based, market-driven and profit-making. Moreover, it would produce employee commitment. During unfreezing stage, diagonal task forces were extensively used on structures and system level. It mainly comprised of individual from different units and functions and exhibiting responsibilities at different level to deal with several aspects involved in change process. The aspects mainly consisted of new uniforms, new practices in staffing, need for MIS (management information system) etc. the major difference from traditional approach was introduced i.e. A bottom-up, less centralized budgeting process. In the climate/interpersonal side involved critical shift in redefining BAs business to represent service instead of transportation. Good interpersonal skills and open climate together with outstanding team-work are key features of service business (Goodstien et al., 1991). To incorporate service environment in BA, the process were developed and team-building activities were taken off-site during movement phase, which are at-present institutionalized. All these changes were successfully implemented due to top management involvement. Marshall himself introduced question-and-answer sessions during training programs. The purpose was to maintain transparency; he shared the information and also gave his opinion for the required change. The acceptance of emotional labour in movement phase was the important step. It was done through Georgiades championed, that conveyed the importance of high energy requirement to deliver quality of service in airline business to the workforce. Any emotional drain in the service can cause permanent psychological damage and critically impact to developing system for the service workers involved emotionally. Another important step was taken in creating internal change agents through retraining of internal personal staffs. The training was taken by supporting line and staff managers. It was found fruitful for managers completing the Managing People First training program in developing peer support groups. Many changes were done internally to BA structures and systems to support this movement. That included new bonus system, sharing of BAs financial gains success. The other initiatives were taken like at Heathrow Airport opening of new Terminal4 for providing more functional units for staffs. Inclusion of new training center through purchase of Chartridge House which was utilized in training staffs and providing information house for MIS enabled managers. Refreezing: Refreezing phase take place after the change has been implemented. In process-oriented studies it has been observed that the refreezing is stage strongly associated with change success (Ginzberg, 1978, p. 59). According to (Schein, 1987) it is that part of the process in which change is embedded within two separate, yet related mechanisms. The first mechanism deals with personal refreezing that implies to the extent to which the persons self-concept have incorporated change and can be integrated with rest of the personality. The second mechanism is relational refreezing that refers to employees personal change to meet the expectation of their peers, supervisor and subordinates. As per (Robbins, 2003) a view refreezing main purpose is to stabilize the new equilibrium resulted through change and that can be achieved by policies and procedures. In BAs refreezing phase, the top management by their continuous involvement and commitment ensured the change is fixed in the system. The staffs which inherited the new BA values were soon to be promoted at higher levels. For educating the workforce many additional programs were introduced. Like, for new staffs included Open Learning and orientation programs, for supervisors supervisory training etc. the training programs were also executed for executive and management levels. To focus on customer service, subordinate development and enthusiasm among staff a new performance appraisal system was introduced. The performance was calculated on both attitude and work results. Another area of BA where immense attention was paid to its symbol and in introducing new refurbished aircraft, upscale uniforms and corporate coat of arms indicating the motto We fly to serve. New teams were developed for providing consistent cabin-crew staffing instead of ad hoc approach of past. Finally, the feedback data on management practices are continuously utilized throughout the system. Analysis of managing change: The change process doesnt seem to be smooth even after BA applied Lewins model change. Since changing behaviour at both organizational and individual levels involves deviations from the existing habitual responses in producing new responses that many times creates awkward situation among involved workforce (Dentinger Derlyn, 2009). Indeed, it could lead to early abandonment of the new management style. The organization must effectively recognize and identify intervening transition state in moving from known present state to a desired future state. A careful management is very essential in the transition state when the planned change is complex and large. The essential part of this change management lies in accepting and recognizing the temporarily lowered effectiveness and disorganization that characterizes the transition state (Bechard, Harris, 1987). In BAs change process, the intensity of chaos and anger that evolved during the transitional phase has been abated and the sign of success is observed. However, many times both inside and outside BA the serious question of wisdom of process were raised due to lack in clarity of outcomes. During such period the involvement and commitment of top management are essential and very important (Walton, 1985) In order to increase involvement in such organizational changes management often require the usage of transition management team that comprises of broad cross-section of members of the organization (Bechard, Harris, 1987). Other methods that account effective involvement is usage of multiple interventions rather than just one like, using symbols and rituals to mark significant achievements and keeping the system open to feedback about the change process (Hornstein, 1971). All these techniques and methods were used in BA program. OD intervention Process consultation: Apart from the various change strategies discussed in BAs change, the considerable use was made of usual organizational development (OD) technologies which included team building, role clarification, structural changes and process consultation to facilitate change. The unique OD intervention process consultation was carried by the consultant to examine pattern of a workforce communications (Burke, 1982). It was done by direct observation of staff, meeting and at opportune times by making observations of happening changes and by raising questions. The main motto behind the process consultation was to change the closed communication style of BA and to create openness in work team. The process consultation played key role in change process and achieving the motto. IMPLICATIONS AND CONCLUDING REMARKS: Fig(5) (Goodstien et al., 1991) As shown in fig(5) BAs conversion to private ownership was found to be successful. After the change completion, BA was turn into profitable organization with the significant rise was observed in passenger, cargos and share price. The BA change effort provides understanding of social psychology perspective of the change process, that gives an important and different perspective to managers, employees etc for coping up with highly competitive environment. In BAs massive change project, the most evident observation is that the change was based on open-system thinking, phased model of managing change and multiple levels involvement for implementing change. Hence, both design and implementation of change effort was heavily dependent on understanding about nature of organization. The change process involved a multifaceted effort by using many leverage points to initiate and support the changes (Burke et al., 1984). Hence, the change process in which transition teams were involved for openness to feedback was efficiently managed and supported by top management. Moreover, the resistance created at all three levels, i.e. individual, structural and systems, and interpersonal, were effectively managed by usage of unfree zing strategies. In BA successful change process many incorporated changes worked positive in stabilizing the company. The most effective change was found in companys culture of creating strong customer-service focus which was lacking in 1982. The fact that service or marketing taken, considering customer perspective, can have substantial payoff for the organization is now endemic to the corporate culture (Hambrick Cannella, 1989). Another aspect that impacted the BAs culture was the way one manages employees that are involved in direct customer interaction, especially for ticket agents and cabin crews. LESSON LEARNT: The lesson learnt from the successful BA change to become service-oriented and market-driven: 1) The

Knorr Soup Marketing Analysis

Knorr Soup Marketing Analysis Knorr product is sold in 87 countries their punch line is Good Food Matters only soup in India which has 18%growth.It holds a majority of market space {55%}.Maggi is one of the main brand of Nestle Knorr nearest competitors .It was first company to launch package soup in India in 1989.New punch line of maggi Taste Bhi Health Bhi after relaunching its brand. QNo.1 which segments are being targeted and strategies used to influence the target segment Target Segment:-Here we can devide the soup brand into two segment 1. Demographics 2. Psychographics Demographics:- Density Urban Same Age 30-35 8-15 Gender Female Male /female Lifecycle stage Married with children Kids early teens Minimum Income 25000 N/a Education Graduate Primary /secondary school Psychographic:- Social class Upper middle ,Low upper and upper- upper class same Life styles Believers, achievers Personality Ambitious , trendy Extrovert, Confident Marketing Strategy (both knorr and Maggi soup) Knorr Maggi soup Product strategy Good food is their main priority Responsible for good and healthy food Categorized soup in three user friendly names Relaunched with what the consumer want Producing tasty and healthy soup for consumers They are also mainly focus on taste and health. Pricing Strategy Knorr soup range between Rs 29 to 33 ,34gm to 65 gm. Maggi range between 29 and 30,40gm to 70gm pack Marginal price increase increase in past few years that effect customer base. Marginal price did not increase so much that help to increase brand loyality. Place strategy Available in almost in all supermarket and departmental stores Maggi soups are available mostly in supermarkets and very few stores No presence in the rural market Very -very less presence in the rural market Promotion strategy Effective advertisement of Knorr as compared to maggi. Less advertisement than Knorr soup Offering new India flavor according to customer demand Offering same flavor approximately three Does not believe in more discount offer Providing various offer and schemes. Recently they are offering maggi noodles with soup pack and 20%extra on some pack. Both are spending huge in promotional activities,both have different strategy to target the market but both have same target market.I compared both the brand because it helps us to give clear picture of both companies strategy. QNo.2 Different promotional tools used and the strategy behind using these tools Promotional tools and strategies:- Besides the proliferation of convenience-driven lifestyles and the array of variants, advertising and marketing too have played significant roles in enlarging the category. Extensive deployment of ATL( Above The Line ) and BTL(Below The Line) tools by manufacturers and marketers have certainly pushed awareness and demand for ready soup mixes. Nestle India, for instance, has been aggressively promoting its Maggi soups through high-frequency television spots, which have played a great role in not just communicating the benefits of the product to target consumers, but its Taste Bhi, HealthBhi tagline has also helped elevate the profile of the category other hand, are positioned as wellness meal solutions. HUL has been banking extensively in employing various mass media to promote its Knorr range of soups. It was due to the creative and intelligent positioning of the brand in mass media that Knorr developed into the leader of the category in India. Its aggressive marketing strategies, strong distribution system and the wide range of flavors make knorr the market leader in this category. Hindustan Unilever further benefited from a realignment of its flavors of Knorr soups under the Snacky, Oriental and Classic ranges, to make it easier for consumers to make buying decisions, as they were now less confused about the different flavors. The company has focused on distribution channels to popularize its new range by ensuring that its up market international flavors in the Oriental and Snaky ranges gain greater visibility in modern outlets, while its Classic range is more visible at kirana stores and in smaller towns and cities. In terms of media promotions, both Knorr and Nestle have been focusing on conveying the taste and health aspects of their soups for the entire family. In 2008, Hindustan Unilever introduced a new advertising campaign, which turned the conventional middle class Indian household image on its head .The campaign for Knorr featured Aman( Actor) making Knorr soup for dinner for the entire family, but mainly to lift the spirits of his wife. With this advertisement, the company not just pitched Knorr as a feel good food, but also promoted its user friendliness. Capital Foods has also been very active and persuasive in promoting its brand. The advertising strategy Nestle and Maggi both promoting health with taste. All the nutritional information and health aspects are mentioned on the packs but they are promoting the range purely to offer something that will gratify the demand for soup. At the retail end, employing strategic merchandising strategies and in store promotions to endorse the product features are also essential. So what is happening in the store? Well, merchandising at the retail end is certainly important as the category is still not the part of shopping list of Indian housewives. Smart merchandising at the retail end can also generate interest and impulse purchase. The soup category is still evolving, it is important to drive penetration and induce trials. Merchandising is the key to drive this category. You would see lots of cross promotions, bundled offers and other kind of promotions in soups. Product features / USPs can be communicated through in store communication. Companies also use especially designed outer cartons as a communication medium; this serves the dual purpose of visual merchandising and stocking on shelf. Q.3.Which strategy out of Pull or Push is used and why? Push Strategy:-A push promotional strategy makes use of a companys sales force and trade promotion activities to create consumer demand for a product. The producer promotes the product to wholesalers, the wholesalers promote it to retailers, and the retailers promote it to consumers. Pull Strategy:-A pull selling strategy is one that requires high spending on advertising and consumer promotion to build up consumer demand for a product. If the strategy is successful, consumers will ask their retailers for the product, the retailers will ask the wholesalers, and the wholesalers will ask the producers So this is clear from the definition this is pull strategy because both Nestle and HUL are spending heavily on promotion activities. Due to that activities consumer demand product from retailers of own choice. QNo.4 Critically Appraise the Promotional strategy of your selected brand. I compared Knorr and Maggie soup both are using aggressive marketing strategy to promote the product . .But if we have to chose one product than Knorr has better promotion and place strategy. But maggi has fewer prices and healthier but need to focus on more promotion. Recently knorr took Kajol as a brand ambassador but Maggie is focusing on small artist. Both companies are not focusing rural area. So they have to focus on rural area because rural area has large potential market. For they can introduce new flavor and new pack with less price. In India there is large potential market for soup so they have to focus on enhancing that maket.Knorr soup has more prices as compared to Maggie soup if they want to increase the market share and want to stand as a market leader they have to provide various promotional offers with knorr soup pack. Knorr brand is more serious about its soup than Maggi. It has connotation of functional brand and after coming into the levers fold, its visibility and presence has been noticed more by consumers. Soup has still a small market and for its consumption to become habit, companies need to invest heavily. Unlike the rest of categories where some amount of efforts may be required. They are targeting women and children for soup because women are caring about children health as well as family health. So they do purchasing most of the time.So it is necessary for that companies to target the segment carefully by giving their benefits about health.This is a very lucrative and conscious market.Women are emotionally attached with the family where as children always believe in masti and mazza while doing eating.They believe in eating those thing which prepare in less time and good in taste.Both the company doing very well for targeting those market with greater spending on promotional advertisement.

Metamorphosis of Eliza Doolittle in Pygmalion by George Bernard Shaw Es

The Metamorphosis of Eliza Doolittle in Pygmalion by George Bernard Shaw    The benefits of acquiring an education are not limited to the academic aspects often associated with it. Part of the edification it bestows includes being enabled to reach new insight, being empowered to cultivate a new awareness, and being endowed with a new understanding of life and of self. In Bernard Shaw's Pygmalion, Eliza Doolittle experiences this type of enlightenment as the result of undergoing a drastic change in social status. With the sponsorship and guidance of Colonel Pickering, Eliza, a common street flower vendor, receives phonetic instruction from Professor Henry Higgins and is transformed into an elegant and refined "duchess" (817). Eliza Doolittle is highly emotional and has dauntless pride; however, her level of confidence increases as she gains a new perception of herself and a new outlook on life through the instruction she receives. Although in the beginning of the play Eliza Doolittle possesses a dignity of self that has persevered despite the lowliness of her social status as a "draggletailed guttersnipe" (817), she has little confidence and a low sense of worth. By describing Eliza's emotional states throughout the play, Shaw illuminates the evolution of Eliza's character. In the opening act when Eliza receives the impression that she is being "charged" for "taking advantage of [a] gentleman's proximity" to persuade him to "buy a flower," Shaw describes that she becomes "terrified" and claims, "I ain't done nothing wrong . . . I've a right to sell flowers . . ." (806). Eliza's initial feeling of fear points to a momentary sense of self-doubt in her character; however, her solid pride leads her to make a declaration in def... ...f" as she "sweeps out" (864). Too proud to be bossed around, Eliza is confident enough to stand her ground and defend her dignity without being timid. Although it was in Eliza's sensitive nature to "fetch slippers," now she "won't care for anybody that doesn't care for [her]" (860). Eliza Doolittle continually manifested pride and a touchy sensitivity; however, once educated, the drastic change of experiencing a substantially improved social standing caused the development of visual confidence in her character. Armed with self-esteem, Eliza had the necessary force in her character to face adversity without doubting herself or relying on the strength of others. Works Cited Shaw, Bernard. Pygmalion.

Media Violence - Helping Youth Understand Death Essay -- Argumentative

Media Violence: Helping Youth Understand Death    We've all heard it before. Blame it on TV, or the movies. If a child bludgeons another child to death with a wrench or shoots a classmate, it is the violent TV programs that they watch which are to blame, not the parents or the supervisors who are supposed to be there to make sure their kids do the right thing. How far is it true that the media is responsible for trivialising death and violence, thus causing the children of America to go out on shooting rampages, or kids in Britain to murder innocent toddlers? First let us look at the way the media portrays death. Death has always been a taboo subject. People do not usually sit around talking about death, especially to children. It may be for that reason that children do not really understand the concept of dying. We constantly see instances in cartoons where a character is killed, but in the next scene, that same character is alive and well again. The fact is that they do not actually die. Characters like Warner Bros. Wild E Coyote never die. They always get up after apparently perishing in a violent way. The South Park character, Kenny, dies a violent death in every single episode (with the exception of the Christmas Special), and that is supposed to be funny. Death is trivialised by the media, and in addition, parents avoid talking about death to their kids, for fear of scaring them, but unknowingly reinforcing the assumption that death is not something to be taken seriously. Death can be described as follows: "It (death) sells newspape rs and insurance policies, invigorates the plots of our television programs, and - judging from our dependency on fossil fuels (84.5% of all U.S. energy consumption in 1995) - - even pow... ...so complex, so contradictory that it is virtually impossible to rule out all other variables to simply measure this one factor." (Death in the mass media). In other words, due to our different ideologies and perspectives, people react to things differently. Therefore, it is difficult to ascertain whether violent acts committed by youth are a direct result of the violence and death they see on TV and in the movies. Who knows, the media may even be helping people develop a healthier attitude towards death. Works Cited Death - An inquiry into man's mortal weakness.

Capital Punishment :: social issues

Capital Punishment In the past, people have invariably felt that if they had been wronged in some way, it was his or her right to take vengeance on the person that had wronged them. This mentality still exists, even today, but in a lesser form because the law has now outlined a person's rights and developed punishments that conform to those rights, yet allow for the retribution for their crime. However, some feel that those laws and punishments are too lax and criminals of today take advantage of them, ie. organized crime, knowing very well that the punishments for their crime, whether it be murder, theft, or any other number of criminal activities, will be so negligible that it may be well worth their risk. Although in the past, the number of crimes that were subjected to capital punishment, defined simply as the death penalty for a crime, were outrageous. Amendments were made to reflect the changes in the society's views on the morality of capital punishment. That resulted in the narrowing down of the list of one hundred crimes to twelve, punishable by the death penalty in 1833, and in 1869 it was cut down yet again to just three: treason, rape, and murder because of violent nature of these crimes. These crimes, even today, are still viewed as violent and should be punished with the highest degree of discipline available to achieve justice. After much public pressure, capital punishment was suspended on a trial run in 1967. This proved to be ineffective, because even though the law stipulated that crimes such as treason or the murder of law enforcement agents, were still to be subjected to the death penalty, the federal cabinet continued to commute those criminals from death to life sentences, hence the law was not being followed and justice was not being served. This soon was followed with capital punishment's abolishment in 1976, as a formal declaration of what was already happening or rather what was not happening. It is felt that because of this and the fact that there has not been an execution since 1967, that today's current form of punishments are no longer a sufficient deterrent for such serious crimes and have contributed to a ever rising crime rate. So, this is where the real issue of whether or not capital punishment should exist begins and such a controversial issue could be best understood if we looked at capital punishment in a perspective of how it fulfils or does not fulfil society's ideas Capital Punishment :: social issues Capital Punishment In the past, people have invariably felt that if they had been wronged in some way, it was his or her right to take vengeance on the person that had wronged them.

Health Hazards in Nursing

Occupational Health Hazards in the Medical Field Kim Chastain AB TECH April 24, 2012 Abstract Medical personnel come into contact with a complex variety of deadly toxins. Contact comes from industrial cleaners, sterilization products, radiation, medications, and mercury. Side effects of these toxic materials are known to lead to a variety of cancers, miscarriages, asthma, birth defects and metabolic syndromes. Government agencies have been negligent in protecting healthcare workers from exposures to these materials.There has never been a government-funded study of these materials and their impact on health and the environment; however independent studies have shown higher rates of disease in healthcare professionals and their children. According to Environmental Working Group (2007), of the 82,000 chemicals in record only around one hundred and eighty have been tested. Thousands of pollutants can be found in any medical setting yet only six have government workplace safety standards. Exposure standards fall to individual facilities to regulate, and vary wildly depending on facility understanding of these toxins. Continued training is recommended when new chemicals and equipment are changed. Healthcare facilities should also be tested on a yearly basis to identify areas of contamination to the employee and patient. Keywords Toxin, hazards, occupational disease In 1970 President Nixon and Congress instituted OSHA to create a safe working environment and NIOSH (The National Institute for Occupational Safety and Health) to research workplace hazards.While OSHA and NIOSH have clear guidelines for common biohazard procedures, almost nothing exists for chemical and toxin exposures. From doctors and nurses to janitors and mail delivery, anyone who comes into contact with these toxins is at risk. The nature of the nurse or doctors exposure is two fold; consumer contaminates from home and industrial contaminates from work. Illnesses reported by medical personnel range fro m chronic skin dermatitis and asthma to acute life threatening conditions; rare cancers, spontaneous abortions, metabolic syndromes and birth defects.The importance of studying the multigenerational human impact of these contaminates is not only to help the lives of the medical employee, but would result in helping to determine the effects on the population as well. Individuals that work in health care should be aware of workplace exposure to hazardous materials found in the medical industry to better protect themselves. While the government plays catch up with science individuals must be proactive in learning about the dangers and what they can do to make their workplace safer. Locating the DangerIt is no surprise that toxins can be found in a medical setting. What does surprise experts is that there are not more regulations and education on how to handle them. There is no question of the impact that these contaminates have on medical personnel and their families. Environmental Wor king Group (EWG) conducted a survey in 2007 to examine exposure and its effects regarding nurses. Fifteen hundred nurses were asked in a survey to list exposure to eleven common toxins found in a medical setting and health problems seen in their children and themselves. The data is staggering.Organizations around the world have conducted their own investigations into workplace exposure and have found the same results. The conclusion is a global pandemic of cancer, miscarriages and illness never before seen in any other workplace. Figure 1 (Environmental Working Group, 2007) An article by Carol Smith (2010) presents InvestigateWests examination into the regulations surrounding medication exposure regulations and chronicles the impact they pose by following the illness of pharmacist Sue Crump. Ms. Crump at the time of the interview was in the end stages of pancreatic cancer.Crump had spent 23 years working in the medical industry mixing chemo drugs. InvestigateWest found that no gover nment agency has any regulations on exposure to drugs; even those that OSHA has deemed as hazardous. OSHA defines hazardous drugs to knowingly cause cancer, birth defects and other illness. Thomas Conner, a researcher for the National Institute for Occupational Safety and Health has spent four decades studying chemo medications on personnel. He emphasizes that, â€Å"There is no other occupation population (that handles) so many known human carcinogens† (Lifesaving Drugs, Deadly Consequences, 2010, para. 1 ). Unlike the US, European countries have taken notice and placed stronger standards to protect its workers, and most have replaced most toxins with green chemicals. Two Danish studies have found â€Å"a significant increased risk of leukemia among oncology nurses and physicians† and extreme risks of multiple cancers for medical workers (A Silent Threat, 2010, para. 10). Concerned over the growing number of studies NIOSH issued an alert on the dangers of handling tox ic drugs; however they are only recommendations and OSHA has no intent on making them regulatory.According to the Environmental Working Groups Survey on Nurses (2007), starting with the Toxic Substance Control Act in 1976, â€Å"the EPA has not reviewed or even begun gathering safety data for more than eighty percent of the chemicals produced or imported in annual quantities exceeding ten thousand pounds† (The System is Broken, para. 4). This brings in to question the very nature of the agencies that have been put into place to protect its citizens. There seems to be no clear cut standard for how these government agencies handle the data and respond to the people or each other.While each one clearly knows and verifies the existence of the dangers they do nothing about it. Common Toxins Anesthetic Gas Anesthesia is commonly used in dental and surgical procedures. Gases escape can from facemasks, tubes and even regulating machines that were created to control exposure. Although NIOSH has recommended exposure limits for many gases used it is primarily to protect the worker during the procedure. These gases have been found to increase neurological issues, lowered fertility in men and women, miscarriage and higher rates of birth defects in children; articulalry neurological complications. Medications According to EWG, the FDA has approved close to six thousand medications. Even in trace amounts these medications can pose serious effects. No study has ever been conducted to examine the hazard of combining medications in humans. Some chemo drugs are capable of damaging DNA and are known cause certain types of rare cancer. Antiretroviral drugs used for HIV treatment are even more dangerous to a developing fetus. Unnecessary exposure to medication has been linked to everything from skin rashes, asthma, cancer, infertility, and birth defects.Latex and personal care products Latex is a common material used in gloves, catheters, and other plastics. Personal care it ems range from shampoo to shaving cream used by patients. Both were linked to asthma and allergies, ranging from mild reactions to life threatening anaphylaxes. Medical professionals have already been found to have to leave the job because of the seriousness of their allergies. Mercury containing devices Mercury can still be found in devices ranging from thermometers, blood pressure cuffs to non-medical devices, such as batteries and thermostats.It is known to be extremely toxic to the brain and nervous system. Neurological disorders have been found to be higher in medical personnel than other occupations. Children born to nurses exposed during pregnancy have higher degrees of developmental delays and central nervous system diseases. Radiation Radiation can be found in medications and used in life saving medical devices. Imaging machines, such as MRI and CAT scans, have been shown to emit radiation even when protections are in place. Radiation exposure has been proven to cause an in creased rate of miscarriage, cancer and birth defects. SterilizationEthylene oxide & Glutaraldehyde are chemicals used to sterilize anything that cannot be sterilized by steam. Whether the exposure was from the liquid form or spread through evaporation it has been linked allergies, anemia and severe migraines. Recommendations Although many of these contaminates are needed, immediate action should be taken place to insure the health of everyone who works near them. Rigorous standards for the handling of and the exposure to toxins; updated and complete profiles for chemicals and their affects on health and the environment; and investigations on healthcare personnel and their children’s lifespans.Education should be as fast paced as chemical production. Healthcare facilities should have mandatory guidelines for replacing hazards with green alternatives when available and only extensively trained personnel allowed to handle them. Conclusions Since the inception of control and reg ulation of toxins and chemicals the government has banned production of only one chemical, and set very few exposure standards for personnel that are exposed to them. Its apparent in the data that what’s being done currently is not working.No other workforce has been asked not only to risk their lives but the lives of their children as well. Bringing to mind the aftermath of 9/11, when the nation watched as military, medical personnel, police, FEMA, and firemen ran to act. Only this time no one seems to be watching. Families of medical workers, like Sue Crumb, have been left to wonder why nothing has been done. It has been reported that the nursing shortage is over but is expected to reemerge again by 2020 as the largest employed group of nurses retire.If the healthcare industry continues to be a hazard to its staff one could only assume that the shortage will become worse. No one can deny that the current burden on the healthcare system is extreme. When our health care profe ssionals begin to get sick the burden will become greater. By stepping forward now, patient and health professional together, perhaps we can save generations of lives from needless loss. References Brody, J. M. (2007).

Gender Schema Theory Essay

Martin and Halverson suggested an alternative to the cognitive-developmental approach proposed by Kohlberg and called it the gender schema theory. In Kohlberg’s theory, children must reach gender consistency before they are able to begin imitating the behaviour of same sex role models. In gender schema theory the early gender identity acquired at about the age of three is the starting point to which children will then begin to look for schemas, schemas are packages of organised clutters of information about gender-appropriate behaviour and children learn these schemas by interacting with people, such as learning which toys to play with, which clothes to wear etc. and these help children to make sense of the world around them and help children to organise their experiences and process new information and also to help self-evaluate themselves, this is to help them feel good about themselves. Support for the gender schema theory was conducted by Martin et al 1995 who showed toys to children aged four to five. Children were informed, before choosing a toy to play with that it was either a girls toy or a boys toy, they were then asked whether they and other boys or girls would like to play with the toys. They found that if a toy, such as a magnet, was given the label of being a boys toy then only boys would play with it. However if boys were told that it was a girl toy then they didn’t want to play with it. Similarly girls would not play with toys labelled for boys. The label given at the start consistently affected the children’s toy preference. It is an important finding in that it highlights the labelling and the categorisation of objects that children are subjected to from a young age, and how their toys can be labelled in the same way as appropriate gender behaviour. A limitation of this research is that an observation of the children and although it has high ecological validity as it is in a real life setting, the children may have shown demand characteristics as the toys were stereotyped for their gender it is questionable if they had guessed the aim of the research and the results may have been due to the children trying to please the researcher as they may have thought they would get punished for choosing the wrong gendered toy to play with and how much of the children’s choice was due to free-will. It was also done in a controlled environment which means that the findings cannot be generalised outside of the research setting. Bauer 1993 wanted to investigate this further and set out to study the way in which children call upon gender schemas when processing information. Pre-school-age and older children have been found to process gender consistent and gender inconsistent information differently so Bauer wanted to see if this was the case in very young children as well. Bauer devised a way to test girls and boys as young as twenty-five months of age. Children observed the experimenter carry out short sequences of stereotypically female, male or gender neutral activities, for example, changing a nappy, shaving a teddy bear or going on a treasure hunt. She tested children by ‘elicited imitation’ both immediately after and 24 hours later to see if they would copy what they had seen. Bauer found that girls showed equivalent quality of recall for all three types of sequence, boys on the other hand showed superior recall of male stereotyped activities, meaning they would not imitate any female behaviour and their recall for gender neutral activities was the same as for male stereotyped activities. These results indicate that boys more than girls tend to make use of gender schemas by the age of twenty-five months and boys appear to remember more accurately event sequences consistent with their own gender, whereas girls show no difference in recall of gender consistent and gender inconsistent information. A limitation of this research is that it could be due to boys being more likely to be penalised by their parents, especially their fathers for carrying out female stereotyped activities, so the children may have played with the male stereotyped toys even if they wanted to play with the other female stereotyped toys. The findings may also be down to that Bauer, who modelled the sequences, is female and the boys may have felt uncomfortable in copying her behaviour. Gender schema theory is parsimonious as it tries to explain gender through cognitive development and does not take into consideration biological gender differences, such as chromosomes, genes or hormones. It is also alpha-bias as it exaggerates the differences between men and women.

INTRODUCTION Dalton's Law of Partial Pressures states that for a mixture of gases in a container, the total pressure is equal to the sum of the pressures of each gas. Where P1 is the partial pressure of gas 1, P2 is the partial pressure of gas 2, and so on†¦ OR In the experiment of the steam distillation,we applied the Dalton’s Law of Partiaal Pressure combined with Ideal Gas Law.Steam distillation is a special type of distillation (a separation process) for temperature sensitive materials like natural aromatic compounds. Steam distillation is employed in the manufacture of essential oil, for instance, perfumes. In this method steam is passed through the plant material containing the desired oils. It is also employed in the synthetic procedures of complex organic compounds. Eucalyptus oil and orange oil are obtained by this method in industrial scale. Figure 1 : Laboratory set-up for steam distillationDistillation Temperature and Composition of Distillate As with ordinary distillations, the boiling point is the temperature at which the total vapor pressure equals the atmospheric pressure. If the vapor pressures of the two components are known at several temperatures, the distillation temperature is found readily by plotting the vapor pressure curves of the individual components and making a third curve showing the sum of the vapor pressures at the various temperature. The steam distillation temperatures will be the point where the sum equals the atmospheric pressure.K nowing the distillation temperature of the mixture and the vapor pressures of the pure components at that temperature, one can calculate the composition of the distillate by means of Dalton’s law of partial pressures. According to Dalton’s law, the total pressure(P) in any mixture of gases is equal to sum of the partial pressures of the individual gaseous components (? A , ? B, etc). The proportion by volume of the two components in the distilling vapor will consequently be equal to the ratio of the partial pressures at that temperature; the molar proportion of the two components (?A and ? B) in steam distillation will be given by the relationship ? A/? B = ? A/ ? B, where ? A + ? B equals the atmospheric pressure. The weight proportion of the components is obtained by introducing the molecular weight (MA and MB) Weight of A / weight of B = (? A x MA) / (? B x MB) Example . Consider a specific case, such as the steam distillation of bromobenzene and water. Since the su m of the individual vapor pressures (see Figure below) attains 760 mm at 95. 2? , the mixture will distill at this temperature. At 95. 2? the vapor pressures are bromobenzene, 120mm and water, 640mm. ccording to Dalton’s law, the vapor at 95. 2? will be composed of molecules of bromobenzene and of water in the proportion 120:640. the proportion by weight of the components can be obtained by introducing their molecular weights. Weight of bromobenze / weight of water = (120 x 157)/(640 x 18) = 1. 63/1. 00 Bromobenzene= {1. 63/(1. 00 + 1. 63)} x 100% = 62% Water = {1. 00/(1. 00 + 1. 63)} x 100% = 38% The weight composition of the distillate will therefore be 62% bromobenzene and 38% water. OBJECTIVE To demonstrate a separation of a mixture by using steam distillation MATERIALS/APPARATUS/EQUIPMENT 00 ml round-bottomed flask, 50 ml Erlenmeyer flask, stoppers, naphthalene, salicylic acid. METHOD Steam Distillation of Turpentine 1. The apparatus for steam distillation are arranged a s shown in Figure 1. 50 ml of distilling flask and 10 ml graduated cylinder is used as the receiver. 2. In the flask, 5 ml, (4. 3g) of turpentine ( bp 156-165 at 760 mm) and 15 ml, of water is placed. 3. Two boiling chips are added and the heating mantle is adjusted to give vigorous boiling. It is essential for the success of this experiment that the mixture boiled rapidly with good mixing of the two phases.Because the point of this experiment is to measure an equilibrium composition and the initial distillate may not have time to equilibrate, the first 1. 5 ml of distillate is discarded and the next 5 ml is collected. 4. The volumes of the water and the turpentine layers at this distillate are recorded. 5. The ratio of the volumes actually found is compared with the ratio calculated from the ideal steam distillation law using the tabulated vapor pressure and densities. 6. The distillation temperature observed is compared with the calculated value.

What properties must a substanc e have for a steam distillation to be practical? For steam distillation of a substance to be carried out, the substance must be heat sensitive. It must possess a lower boiling point than water.This method is also advisable for highly volatile liquids because highly volatile liquids denatures at high temperatures. 2. What are the advantages and the disadvantages of steam distillation as a method of purification? Among the advantages of steam distillation is organic compounds which is steam distilled will evaporate at lower temperatures, most probably below their temperature of denaturation. Besides that, heat sensitive aromatic compounds which cannot be distilled by direct heating can be processed. On the other hand, the disadvantages of this method are this method is not exactly suitable for all types of aromatic oils.Only certain types of aromatic oils are suitable to be processed using this method. Furthermore the heat is difficult to control causing the rate of distillation to be variable. -Our group apparatus got some problems. The turpentine that has been distillated accumulated at the joint of the apparatus. This is because the apparatus less slope, leads the turpentine to accumulate, resulting long time to collect the distillated turpentine. CONCLUSION Steam distillation is a special type of distillation (a separation process) for temperature sensitive materials like natural aromatic compounds.Many organic compounds tend to decompose at high sustained temperatures. Separation by normal distillation would then not be an option, so water or steam is introduced into the distillation apparatus. By adding water or steam, the boiling points of the compounds are depressed, allowing them to evaporate at lower temperatures, preferably below the temperatures at which the deterioration of the material becomes appreciable. Therefore, as the conclusion, it is proven that turpentine and water can be separated by using steam distillation.It is also known that water ha s a higher density than turpentine. Next, Dalton's law (also called Dalton's law of partial pressures) states that the total pressure exerted by a gaseous mixture is equal to the sum of the partial pressures of each individual component in a gas mixture. This empirical law was observed by John Dalton in 1801 and is related to the ideal gas laws. On the other hand, the ideal gas law is stated as the equation of state of a hypothetical ideal gas. It is a good approximation to the behavior of many gases under many conditions, although it has several limitationsTherefore, as both of these laws are involved, we can conclude that both Dalton’s Law and Ideal Gas Law are applicable in steam distillation. Based on the result of the experiment, water contains 80% and turpentine contain 20% portion. Some errors might have occurred during the experiment that caused the results to be differed from the theory. During the experiment, the apparatus must handle carefully because it is easily broken. To increase the accuracy of the result, thermometer is used in the flask so we can read the temperature in the flask.We must use stopper to close the flask because it can avoid the water vapour escape to the environment REFERENCES John R.

Pacific Grove, CA: Brooks/Cole Publishing Company APPENDICES Steam Distillation Experiment 2: Isolation of Eugenol from Cloves Background; Readings on Vapor pressure, Raoult’s Law from TRO: A mixture of the essential oils, eugenol and acetyleugenol, will be steam distilled from cloves. These compounds are isolated from aqueous distillate by extraction into dichloromethane. The dichloromethane solution is shaken with aqueous sodium hydroxide, which will react with eugenol, to yield the sodium salt of eugenol in the basic aqueous layer, and acetyleugenol in the organic layer. The basic aqueous layer can be acidified to re-extract eugenol from it.And the organic layer can be dried and concentrated to yield acetyleugenol The principle of steam distillation is based on the fact that two immiscible liquids will boil at a lower temperature than the boiling points of either pure component, because the total vapor pressure of the heterogeneous mixture is simply the sum of the vapor pressures of the individual components (i. e. PT = PoA + PoB, where Po is the vapor pressure of the pure liquids). This leads to a higher vapor pressure for the mixture than would be predicted for a solution using Raoult’s Law(applies for iscible mixtures) (that is PT = Po(A)n(A) + Po(B)n(B), where n is the mole fraction of the component in the mixture). The higher total vapor pressure leads to a lower boiling point for the mixture than for either single component. The boiling point of eugenol, an oil found in cloves, is 248  °C, but it can be isolated at a lower temperature by performing a co-distillation with water. Steam distillation allows separating substances at lower temperatures which is useful since many organic compounds tend to decompose at high temperatures which regular distillation would require.For steam distillation to be successful, the material to be isolated must be insoluble in water. Usually   these compounds have a low vapour pressure. After mixing them with water, however, the mixture will distil when the sum of the two vapour pre ssures reaches atmospheric pressure. It follows, then, that this must happen below the boiling point of water. Note that by steam distillation, as long as water is present, the high-boiling component vaporizes at a temperature well below its normal boiling point without using a vacuum.Since eugenol is not soluble in water, the concentration of the eugenol in the vapor over the boiling eugenol– water suspension does not depend on concentration of the eugenol. The relative amounts of eugenol and water in the vapor simply depend on the vapor pressures of the pure materials. The vapor pressure of water at 100  °C is 760 torr, and the vapor pressure of eugenol at 100  °C is approximately 4 torr; (Note, the suspension boils when it’s vapor pressure is equal to the external pressure.Since both the eugenol and the water are contributing to the vapor pressure of the suspension, the suspension will boil before either pure substance would normally boil. ) Since the distillate will contain both water and eugenol, the eugenol must be extracted from the water using an organic solvent. Once the eugenol is extracted into an organic solvent,the organic layer is separated from the aqueous layer and dried. The eugenol is finally isolated by evaporation of the organic solvent. When   the sum of the separate vapor pressures equals the total pressure, he mixture boils and P =P(A) + P(B) Where PA is vapor pressure of pure water A PB is vapor pressure of pure B 1 Then the vapor composition is Y (A)= PA/P Y(B) =PB/P Dalton’s Law: PAV1 = nART1 and PBV2 = nBRT2 V1 = V2 and T1 = T2 n = moles, The ratio moles of B distilled to moles of A distilled is OH OCH3 OAc OCH3 Eugenol AcetyleugenolObjectives: To extract Eugenol and Acetyleugeonol from cloves To separate the mixture of eugenol and acetyleugenol using their acid- ­? base properties. To characterize eugenol and acetyleugenol using TLC(Rf values) andRefractive index. Glassware: Beaker to mass the cloves, Er lenmeyer flasks(2, 50- ­? ml), storage container+ distillation glassware(there should be an assembly in the fume hood) Procedure: Week 1: Steam Distillation Place 10 g of whole cloves (ground using a mortar and pestle by the teacher) in a 100-mL round-bottom flask, add 50 mL of water, and set up an apparatus for simple distillation- steam (will be set up in the fumehood and you can draw the set up while in the lab) will be generated in situ(50 ml of water added to the flask will generate the steam).Heat the flask until boiling begins, then reduce the heat just enough to prevent foam from being carried over into the receiver. Use a 50-mL Erlenmeyer flask as a receiver(the distillate will collect in the flask thro a funnel) and transfer periodically your distillate to a 50-mL graduated cylinder. While you have removed one receiver, do not forget to replace the Erlenmeyer flask with a second one(that is clean and dry). 2 Caution: It is important that the cloves remain covered with wa ter at all times. Or else, the cloves will burn and smoke!Also, the distillation has to be steady. If not the mixture will foam and the foam will drop down the condenser into the receiving flask. And this would contaminate the distillate. Save the distillate in a tightly capped bottle for the following week. Week 2: Separation of Eugenol and Acetyleugenol via acid/base extraction Place the 50 mL of distillate in a 125-mL separatory funnel and extract with three 10-mL portions of dichloromethane. Combine the dichloromethane extracts and reserve 1 mL for thin layer chromatography. teacher will explain this step) To separate eugenol from acetyleugenol: pour back the dichloromethane extracts into the separatory funnel, extract the dichloromethane solution with 5% aqueous sodium hydroxide solution. Carry out this extraction three times, using 5-mL portions of sodium hydroxide each time. KEEP the aqueous extracts (it contains eugenol) and dry the organic layer over sodium sulfate (add eno ugh so the drying agent no longer clumps together but appears to be a dry powder as it settles in the solution).Swirl the flask to complete the drying process and let the drying agent settle for 1 minute before decanting into a DRY and TARED Erlenmeyer flask, rinse the drying agent with two 2-mL portions of dichloromethane. Evaporate the solution on a steam bath, the residue should be aetyleugenol. Acidify the combined aqueous extracts to pH 1 with concentrated hydrochloric acid (use Litmus paper to monitor the pH), and then extract the eugenol with three 5-mL portions of dichloromethane.Dry the combined extracts over sodium sulfate, as done before, decant into a DRY and TARED Erlenmeyer flask, and evaporate the solution on a steam bath, the residue should be eugenol. Cleaning Up: Combine all aqueous layers, neutralize with sodium carbonate, dilute with water, and flush down the drain. Any solutions containing dichloromethane should be placed in the halogenated organic waste contain er. Wash up all glassware with soap and water. Analysis: Calculate the weight percent yields of eugenol and acetyleugenol oils based on the weight of cloves used. Analyze your products sing refraction index. Analyze your products using thin layer chromatography (TLC).

Then the TLC plate is developed. For the next step (co-spotting), an authentic sample of the 3 ompound closest in Rf value to the unknown is chosen. TLC co-spotting of a second plate allows for preliminary identification of your compound. Three spots are applied to the adsorbent on the baseline of the TLC plate: the purified unknown, an authentic sample, and a co-spot of unknown and authentic sample. If the developed TLC plate shows only one row of spots, it can be concluded that the unknown has been purifed, and that the unknown is possibly the same compound as the authentic sample.However, because Rf values are relative, not absolute, some compounds may have very similar Rf values Pre- ­? ab: FOR WEEK 1 only: All the required formulae for the caculations have been presented here.
