Bdm - Essay Example 8.56135 7.77005 Inter-quartile range (IQR): The median happens to be in the middle of the sorted data. Similarly the first quartile can be defined as 1/4 of the way through the sorted data, and the third quartile to be 3/4 of the way through the sorted data. Second quartile is also known as the median. The range between the first and third quartiles includes half of the data. The size of the range (i.e., the difference between the third quartile and the first quartile) is another measurement of variability called the inter-quartile range or IQR. For normally distributed data: IQR = 1.35 From the above calculations it appears the reorganization exercise has not been a grand success. Though it appears to have tightened some loose ends but still the average output remains the same.

Tourism Operations Management Essay Example | Topics and Well Written Essays - 3750 words

Tourism Operations Management - Essay Example Task 1(L01) Tour operations sector In travel and tourism, tour operators are the ones which combine two or more businesses in a package which is ultimately offered to the consumer as a holiday package. In UK there are two kinds of tour operators- mainstream tour operators and specialist tour operators (Meyers, n.d, pp.8-9). Mainstream tour operators are the ones who sell mainstream tour packages like air, sea, sand sun to the customers while the niche tour operators serve highly specified tour packages like beaches but of a lower standard. The major mainstream companies in UK are Thompson or Thompson Holidays, Thomas Cook, Airtours and First Choice. The products offered by them are the beaches in locations like the Caribbean, Thailand and Malaysia. A number of specialist tour companies have also come up in UK as there is little competition among the specialist tour operators. Major tour operators- introduction Thompson or Thompson Holidays is a part of TUI travel PLC (Cruiseship rati ngs and reviews all cruises with operator Thompson Holidays, n.d). The company known originally as Thompson Tour Operations was renamed as Thompson Holidays in 1997. It was floated in the London stock exchanges in 1998. Thomas Cook was started in 1841 by a person named Thomas Cook. He floated his company commercially in 1845 for the first time. A travel brochure was also provided by it for the first time (Thomas Cook history, n.d). Airtours is well known for providing innovative tour packages to its customers according to the changing lifestyles. It targets the cheap or lower budget market but because of the high level of innovation and ideas it has become one of the top market leaders in UK. (Airtours, n.d). First Choice is the fourth largest tour operator in UK. It was established in the beginning of the 1970s when two companies named Continental Air Brokers and Economy World Travel decided to merge and form Owners Abroad (Wholesale) Ltd. in 1973. Later, the company decided to cha nge its corporate name and in 1994 the company was renamed as First Choice Holidays (First Choice Holidays PLC History, n.d). Since mid-1997, these four players occupy 53% of the holiday market in UK in 2000 (Pender, Sharpleyfirst, n.d, pp.48). Market Segmentation UK travel and tourism market is more oligopolistic in nature because of the presence of only four major players. The process of dividing the consumer base on the basis of common needs is known as market segmentation. The British travel market is divided into the following five segments. These five segments are categorized on the level of experience they have in traveling and the attitude and comforts they seek from the travel experiences. †¢ Self-Challengers †¢ Comfort Adventurers †¢ Cocoon Travelers †¢ Pushing Boundaries †¢ Taste & Try Self-Challengers are the groups who are more affluent economically and are highly educated. They are most likely to be unmarried and between 18 to 75 years of age. Australia seems to be the favorite holiday destination amongst the self challengers. They are the travelers who go to holidays with a learning quest. Comfort Adventurers are the ones who have the curiosity to visit the places before they are visited by the local market. They do not compromise with safety and comforts. Cocoon Travelers are the ones who take inspiration from newspapers and experiences of others. They are basically married, having

Questions on Psychology of Aging - Essay Example The SOC theory "involves an orchestration of selection, optimization, and compensation." When an individual decides on the path or goal he wants to achieve, this process is called selection. "During ontogeny, there are several additional sources for selection: individuals and societies sample from a population of possibilities or opportunities (.), limited individual capacity in time and resources, incompatibility of goals and outcomes, and age-related changes. The activities he will do to hit the target is optimization. If the individual can no longer keep his goal he resorts in goal-relevant means to maintain success - this is compensation. An aging journalist who used to go on field for a daily beat applies the theory of SOC in continuously writing news stories (selection), he ensures that he meets with the right sources to beat his deadline and be able to deliver a good output (optimization), but old age hinders him from doing field work everyday, hence, he opted to have a bi-weekly column in a broadsheet to maintain his keenness and visibility in the world of news (compensation). 2. Schaie (1994) asked whether there are differences in life-course patterns for various intellectual abilities with age (i.e., whether different abilities show different trajectories with age). Briefly discuss the answer to this question based on his results (6 points). Also note when reliable decrements in intellectual ability are detectible (2 points) and what role cohort effects might play (2 points). Answer: In his study, K. Warner Schaie (1994), have shown that "there is no uniform pattern of age-related changes across all intellectual abilities, and that studies of an overall index of intellectual ability () do not suffice to monitor age changes and age differences in intellectual functioning for either individuals or groups." The uniqueness of human mind, as well as, cohort, and gender are among the factors that makes the non-uniform pattern of age-related changes in the IQ. The age of 60 is the usual retirement age in most countries. Schaie's study shows "decrements in most psychometric abilities" mostly occur at the age of 60 onwards. Regardless of the individual pathology or genetic factors, "reliable average decrement can be found for all psychometric abilities by age 74. Cohort, generation, or peers also affect an individual's intellectual ability. Although "() patterns of socialization unique to a given sex role is specific historical period may be a major determinant of the pattern of change in abilities." 3. Imagine that you are asked by congress to develop a nation-wide training program that would enhance older adults' cognitive functioning. Based on the results from the Schaie and Willis (1986) study, where they trained reasoning and spatial ability in older adults, would you tell congress that a training program would work (5 points) Why or why not (5 points) Answer: I would be very glad to recommend to the Congress a training program to enhance adults' cognitive functioning. Based on Schaie and Willis (1986) study, "inductive reasoning training help improve everyday problem solving ability, particularly for older adults in their late 70s or early 80s. In the present time where a lot of concerns arise, that even a primary pupil encounter various perplexing matters (classroom and family politics), a cognitive training would be of help. It will boost the future, as well as the present generation's

Answer questions - Assignment Example The company should address all avenues of accident that have led to previous tragedies in the mining operations. One of the suitable approaches to pursue is increasing investment in safety at the mining site. It is also crucial to investigate tragedies that befell mines comprehensively. Subsequently, it is important to order for the immediate closure of sites that appear insecure. The company should also ensure effectiveness when adhering to procedures, policies and standards. The other important measure that Massey Energy will be compelled to takes will be to ensure speedy and appropriate response to incidences of tragedy and accidents at the mines. The closure of dangerous sites will serve as an economic stimulus because the organization will concentrate on productive sites and boost their revenue. In addition, focusing on safety system will enhance productivity and allow the organization to improve efficiency and output. It means that fewer accidents will occur and majority of the personnel will be available to

Administrative Theories in Public Administration Essay Example for Free

Administrative Theories in Public Administration Essay I have never thought that administrative theories in Public Administration has been established back in 1800 with theorist who have discovered or developed and now has been part of the system of the Philippine government. The earliest contributors to our understanding of management theory included practicing managers as well as social scientist. More recent theorist has tended to be academic or management consultants. The early theorist can be divided into 2 main groups – the practicing managers such, as Taylors and Fayol and the social scientists, such as Mayo and Mc Gregor. Meet the Mr. Taylor, the theorist of Scientific Management. Frederick Winslow Taylor (1856-1915), one of the early practical manager-theorist, born in Boston, Massachusetts, spent the greater part of his life working on the problems of achieving greater efficiency on the shop-floor where he manages. The solution he came up with was based directly on his own experience at work, initially as a shop floor worker and later as a manager. He pioneers scientific management which includes: The systematic study of the relationships between and tasks to redesign the work for higher efficiency. Taylor sought to reduce the time a worker spent on each task by optimizing the way the task was done. Scientific Management Theory Organizations were seeking ways to better satisfy customer needs Machinery was changing the way goods were produced Managers had to increase the efficiency of the worker-task mix According to him, there are 4 Principles to increase efficiency that are: a. Study the way the job is performed now and determine new ways to do it. Gather detailed, time and motion information; try different methods to see which is best b. Codify the method into rules – Teach to all workers c. Select workers whose skills match the rules set in step2 d. Establish a fair level of performance and pay for higher performance – Workers should benefit from higher output But, Taylor recognizes that the measures he was proposing would appear to be more than just a new method – they would be revolutionary. He stated that the outset that â€Å"scientific management† would require a complete mental revolution on the part of management and workers. Henry Fayol (1841-1924) – father of modern management theory He divided industrial into 6 groups: technical, commercial, financial, security, accounting managerial And formulated the 14 Principles of management which we are using it every day in our daily activities, allow me to enumerate them and somehow expand a little. Division of Labor – allows for job specialization, Authority and responsibility – Fayol noted firms can have too much specialization leading to poor quality and worker involvement. Unity of command – employees should have one boss. Line of authority – a clear chain from top to bottom of the firm. Centralization – the degree to which authority rests at the very top. Unity of direction – one plan of action to guide the organization. Equity – treat all employees fairly in justice and respect. Order – each employee is put where they have the most value. Initiative – encourages innovation. Discipline – obedient, applied, respectful employees needed. Remuneration of Personnel – The payment system contributes to the success. Stability of nature – long term employment is important. General interest over personal interest – the organization takes precedence over the individual. Esprit de corps – share enthusiasm or devotion to the organization. I have added here some of the theorist I researched which I consider to be worth sharing. Mary Parker – an influential leader in early managerial theory. a. Suggested workers help in analyzing their jobs for improvements b. The worker knows the best way to improve the job c. If workers have the knowledge of the task, then they should control the task. The Hawthorne Studies It appears that the workers enjoyed the attention they received as part of the study and were more productive. Contingency Theory – Assumes there is no one best way to manage The environment impact the organization and managers must be flexible to react to environmental changes The way the organization is designed, control systems selected, depend on the environment Conclusion As management theories evolved in centuries, the principles and ideas were never changed yet it has been a guiding value to those who are in public nor private service and to those who are employed and business people. It’s amazing how they have passed on to many generations of people who wanted to learn and use the theories. The theories have been explicit in explanations and user-friendly, though there are theorists who have presented different thoughts on the earlier theorist but if we examine deeply, it’s all the same, only presented in different design. Before I end, I would just like to emphasize the last part of the theories because it speaks about our relationship with the environment and how we will relate environmental, Technological environments change rapidly so must managers.

Antimicrobial Activity of Oil Extract from Marang Seeds

Antimicrobial Activity of Oil Extract from Marang Seeds Antimicrobial Activity of Oil Extract from Marang Seeds (Artocarpus odoratissimus)  against Escherichia coli and Staphylococcus epidermidis Introduction Essential oils are widely gaining interest a component in medicinal products, food industry and pharmaceutical industry. Many studies were conducted to identify the antimicrobial, antifungal and insecticidal activities of essential oils obtained from plants. Essential oils have many therapeutic activities and they aid the distribution of drugs and antiseptics. Furthermore, the testing of plant extracts for its antimicrobial activity has always been of great attention to scientists looking for new sources for drugs for the treatment of various diseases (Nagala et al., 2013). Antimicrobial Compounds from Plants Phenols According to Cetin-Karaca (2011), phenolic compounds are one of the most diverse groups of secondary metabolites found in edible plants. They are found in a wide variety of fruits, vegetables, nuts, seeds, stems and flowers. There are different classes of polyphenols known as tannins, lignins and flavonoids. Cinnamic and caffeic acids are common representatives of a wide group of phenylpropane-derived compounds which are in the highest oxidation state. Herbs such as tarragon and thyme both contain caffeic acid that is effective against viruses, bacteria and fungi. Catechol and pyrogallol both are hydroxylated phenols, shown to be toxic to microorganisms. Catechol has two 2OH groups, and pyrogallol has three. The site(s) and number of hydroxyl groups on the phenol group are thought to be related to their relative toxicity to microorganisms, with evidence that increased hydroxylation results in increased toxicity (Cowan, 1999). Flavonoids Flavonoids are the most widely occurring polyphenol and are present in almost every form of human consumed vegetation. Flavonoids are potent antioxidants, free radical scavengers and metal chelators; they inhibit lipid peroxidation and exhibit various physiological activities including anti-inflammatory, anti-allergic, anti-carcinogenic, anti-hypertensive, anti-arthritic and antimicrobial activities (Cetin-Karaca, 2011). Flavonoids are also hydroxylated phenolic substances but occur as a C6-C3 unit linked to an aromatic ring. Since they are known to be synthesized by plants in response to microbial infection, it should not be surprising that they have been found in vitro to be effective antimicrobial substances against a wide array of microorganisms. Catechins, the most reduced form of the C3 unit in flavonoid compounds, have been extensively researched due to their occurrence in oolong green teas. It was noticed some time ago that teas exerted antimicrobial activity and that they contain a mixture of catechin compounds. These compounds inhibited in vitro Vibrio cholerae, Streptococcus mutans, Shigella and other bacteria and microorganisms (Cowan, 1999). Plant Extracts as Potential Antibacterial Agents Numerous studies investigated about the antimicrobial activity of plant extracts against a great number of bacterial species. Plant extracts were prepared from fresh or dried plant material using conventional extraction methods (Soxhlet extraction, maceration, percolation). Extraction is process of separation of active compounds from plant material using different solvents. During extraction, solvents diffuse into the plant material and solubilise compounds with similar polarity. At the end of the extraction, solvents have been evaporated, so that an extract is a concentrated mixture of plant active compounds. Successful extraction is largely dependent on the type of solvent used in the extraction procedure. Water extracts and extracts from organic solvents such as methanol, ethanol, acetone and chloroform are usually used. Diffusion and dilution method are two types of susceptibility test used to determine the antibacterial efficacy of plant extracts. Diffusion method is a qualitati ve test which allows classification of bacteria as susceptible or resistant to the tested plant extract according to size of diameter of the zone of inhibition. In dilution method, the activity of plant extracts is determined as Minimum Inhibitory Concentration (MIC). MIC is defined as the lowest concentration able to inhibit bacterial growth (Stefanovic, et al., 2012). Marang (Artocarpus odoratissimus) Artocarpus odoratissimus is also known as Marang, Johey oak or Tarap which is a tropical fruit tree native to Asia. It belongs to the Moraceae family and is closely related to Jackfruit (Artocarpus heterophyllus) and breadfruit (Artocarpus comminis). It originated in Borneo and has been introduced into neighbouring countries, including the Philippines, Malaysia and Thailand. It is an evergreen tree, which can grow up to 25 m tall and has a 40 cm diameter trunk with low buttresses. The leaves are broadly elliptic to obovate at around 16to 50cm long and 11to 28cmwide. They are cuneated at base to slightly decurrent, margin entire or shallowly crenate, and apex blunt or shortly acuminate. It is a monoecious plant so one plant is enough for the production of fruit. The fruit is green, ovoid in shape, quite large, averaging about 16 cm in length, 13 cm in diameter and weighing about 1 kg (KPR Gardeners Club, 2009). It is roundish oblong, regular, and thickly studded with short, brittle, g reenish yellow spines. The rind is thick and fleshy. The flesh is snowy white, very sweet when ripe, juicy and very aromatic. The flesh is separated into segments clinging to the central core and each segment contains a seed. The seeds are many, whitish, 8 Ãâ€" 15 mm in size, smooth surfaced and readily separated from the flesh (Subhadrabandhu, 2001). Escherichia coli Escherichia coliis the most prevalent infecting organism in the family of gram-negative bacteria known as enterobacteriaceae.E. coli is a Gram-negative, rod-shaped bacterium propelled by long, rapidly rotating flagella. Escherichia colibacteria were discovered in the human colon in 1885 by German bacteriologist Theodor Escherich. Dr. Escherich also showed that certain strains of the bacterium were responsible for infant diarrhea and gastroenteritis, an important public health discovery. AlthoughE. coli bacteria were initially called Bacterium coli, the name was later changed toEscherichia colito honor its discoverer (Clark, 2005). It is part of the normal flora of the mouth and gut and helps protect the intestinal tract from bacterial infection, aids in digestion, and produces small amounts of vitamins B12 and K. The bacterium, which is also found in soil and water, is widely used in laboratory research and is said to be the most thoroughly studied life form (The Columbia Electronic Encyclopedia, 2012). Staphylococcus epidermidis Staphylococcus epidermidis belongs to the genus Staphylococcus, and they are facultative anaerobes (Wiedemer, 2012). Staphylococcus epidermidis is a well characterized, non-fastidious, and it is a gram positive bacteria. Staphylococcus epidermidis is a coagulase – negative staphylococcus (CNS) they are found and colonizes the skin and the mucous membranes of the human body and they play an important part of it normal flora (Sousa et al., 2008). These species of staphylococcus secretes and produces a biofilm of polysaccharides that protects the cell against the host immune system or antibiotic treatments (Schjorring et al., 2002). These staphylococci are mainly dispersed during skin to skin contact using medical instruments and procedures. Staphylococcus epidermidis can cause infections in humans like meningitis, urinary tract infection (UTI) conjunctivitis, and endocarditis (Wiedemer, 2012). Bibliography Cetin-Karaca, H. (2011).

Sakis Stories and the Impression they Create about Adult-Child Relatio

Saki's Stories and the Impression they Create about Adult-Child Relationships In order to answer this question I am going to be focusing on three of Saki?s stories; the story-teller, the lumber room and the open window. Children at the time Hector Munro (Saki) was writing these stories would have had very vivid imagination; this is shown in Saki's story 'The Open Window' when the niece makes up the saga of Mr Sappleton's death, illustrates how imaginative children can be, and that adults are very easily fooled. Fooling adults is a key theme in Saki's stories; another time when it occurs is in the story 'The Lumber Room' when Nicholas dupes his aunt into believing that he is somehow trying to get into the gooseberry garden, but instead has no intention of doing so but does sn...
