Behaviourism As A Language Learning Theory English Language Essay

Behaviourism As A Language Learning Theory English Language Essay Introduction Human beings learn every now and then. According to Cambridge Advanced Dictionary (2003), learning can be defined as an activity of obtaining knowledge. We human usually learn or gain knowledge either in a conscious way or subconscious way. Learning is not necessary must be conducted in a formal way such as tutorial, class or lecture; however, we also learn when we having a conversation with others or be it listening to the radio. Learning is a relatively permanent change in a behavioral tendency and is the result of reinforced practice (1963, cited in Kimble and Garmezy, 1987, p.6). There are actually a few theories been used to describe how knowledge or language is acquired namely Behaviourism, Innatism and Interactionism. For the first part of this assignment will explain these theories various approaches and principles. Then, this paper will focus on the pedagogical implications of each theory in teaching English as a Second Language. Part two will focus on examining the underlying learning theories which could have influenced the teaching-learning activities from a textbook. By the end of this paper, students will be able to differentiate learning theories and adopt the most suitable ones into his/her teaching career. Behaviourism is the earliest language learning theory which is propounded by J.B. Watson (1878-1957) in 1913. This theory is supported and believed by some behaviourists who are Skinner, Pavlov and Thorndike; also, profoundly developed the theory of behaviourism on learning. Behaviourism focuses on observable behaviours which are changed as the symptoms of learning. According to Brown (1987: 17), the behaviouristic approach focuses on the immediately perceptible aspects of linguistic behaviour the publicly observable responses. Learning only occurs when there are changes in behaviour and observable as an evidence of changing. Feeling and mental process are not accepted in Skinners human behaviours theory; however, he still accepted the existence of mind. Behaviourists consider learning a language as a set of mechanical habits which are formed through a process of imitation and repetition. Humans learn a language through repeating the same form and text until it becomes a habit. Children imitate the sounds and patterns which they hear around (Lightbown Spada: 1999). So, it was proposed that learners would repeat words they heard and tried to use it in their conversation until it became a regular basis in life. Behaviourists therefore think that learning a language especially second language (L2) should be learnt through extensive drill and practice. Besides that, behaviourists also justified that learning a new language is learning a new set of habit. According to Ellis (1990), learning could be effected by manipulating the environment to provide the required experience. This lead to the theory formation of habit is related to the environment where learning process actually takes place. These habits formation and the environment are recognized as Stimulus-Response (S-R) by Pavlov and Skinner. In 1950s, school of psychology successfully prevailed S-R in the form of behaviourism to ensure the connection between both elements. Behaviourists might consider effective language behaviour to be the production of correct responses to stimuli (Brown: 1987). According to the theory, behaviour happens in casual, associative chains; all learning is thus characterized as associative learning, or habit formation, brought about by the repeated association of a stilmulus with a response Hadley (1993, cited in Hilgard 1962, p.45). So, its best kn own proponent, B.F. Skinner used rats conclude that conditioning has a 3-state procedure: stilmulus, response and reinforcement. From here, Skinner presumed that human learning and animal learning are parallel; thus, L2 learning is also similar as other kind of learning can be explained by the same laws as well as principles. Every process of learning has to be followed by reinforcement. All learning is the establishment of habits as the results of reinforcement and reward (Demirezen: 1988). In behaviourism, there are two different types of reinforcement. The first one is positive reinforcement, where the response or behaviour is strengthened and positively augmented by praise or reward. For instance, when a student answer a question correct and the teacher award him/her a star, then the student will try to answer another question because he/she is more confident and motivated. In contrast, the second reinforcement is negative reinforcement. If a student been scolded by his/her teacher after got the answer wrong, he/she would tend not to give answer by the next Q A session because it would make him/her feel embarrassed. In short, positive reinforcement helps learners develop correct habits. Furthermore, Behaviourist learning theory also claimed that old habits interfere with the acquisition of new ones. Learning of the L2 would be facilitated since all the learners had to do was to transfer L1 habits (Ellis: 1990). That means errors in first language learning (L1) are the result of interference in L2. It has to be avoided and prevent L1 interference happened as well as corrected on the spot if they do occur. One of the examples of extensively drilling in learning is Audio Lingual Method which is an American method. It is function as a structural approach designed to develop oral communication fluency in L2. Audio Lingual Method is focuses on accuracy (pronunciation and intonation), mistakes should be avoided and corrected immediately if it happened. Ellis (1990: 23) wrote: for learning to be effective habits had to become automatic. In short, language learnings pattern has to be over-learnt and the content based on common days dialogues as well as expression. If follow by the positive reinforcement which will help students to develop correct habits. By then, learning the structures of the language is more emphasized if compare to the vocabulary. Innatism In 1959, Noam Chomsky published Review of Verbal Behaviour to critically criticize Skinners theory of Behaviourism. Innatists claimed that linguistic knowledge is an abstract nature no solely on the set of mechanical habits (imitation and repetition). According to Ellis (1990), new grammatical forms were not acquired through imitation and not stamped in through practice. Language is too complex and occurs too rapidly for it to be learned through imitation. In other words, competence could not be achieved simply to performance due to insufficient of input to enable the child to discover the hidden rules (Ellis: 1990). For Chomsky, children are not necessary to be taught because they will learn in terms of walking at about same age; meanwhile, the environments contribute the most in learning. Chomsky and other linguists argued that children are credited with a special ability to discover the underlying rules of a language system within themselves. This innate and special ability is cal led Language Acquisition Device (LAD) or a little black box and Universal Grammar (UG) which exist in the brain. The LAD contains a set of abstract principles common to all languages which enables the child to produce infinite variety of sentences and construct grammatical sentences. UG was claimed to help children to extract the rules of their language and to avoid grammatical errors (Fromkin, Rodman, Hyams 2007). Therefore, a child has to listen and learn grammar to trigger the LAD or UG which then enables the child to discover the rules of the language. In short, human beings acquire and adapt language in any environment along with input of language or linguistic knowledge. Monitor Model In 1982, Stephen Krashen, who have had a great influence on language learning and acquisition by stimulated the Monitor Model. The Monitor Model consists of five hypotheses which are The Input Hypothesis, The Acquisition-Learning Hypothesis, The Monitor Hypothesis, The Natural Order Hypothesis and The Affective Filter Hypothesis. The first hypothesis is Input Hypothesis. This hypothesis claimed that language acquisition takes place through comprehension input (CI). Comprehensible input is available when students or learners are able to understand messages and their attention is focused on meaning. Besides that, comprehensible input will only occur if the inputs forms and structures pitch one level above the level of student (CI = i + 1). Whatever it pitches one level above learners current level competence, both comprehension and acquisition will occur. Learners will not benefit anything in learning if the input has no element of challenge; however, they will not acquire the knowledge if the input is too difficult. Acquisition leads to the result of comprehensible input and not production or quantity. Comprehensible Input does not have to be fine-tuned and reading is crucial to language acquisition*. The second hypothesis is Acquisition-Learning Hypothesis. This hypothesis explained that adults have two distinct and independent ways to develop knowledge of a second language learning and acquisition. In Krashens view, a learner learns second language whereas a child picks up or acquires his/her mother tongue (first language). Learning is a conscious process with attention to form and error correction. In contrast, acquisition is a subconscious process when a learner is engaged in meaningful communication and focus is on meaning. Both acquired and learned knowledge are separately; therefore, learned knowledge cannot be converted into acquired knowledge. If learner acquires knowledge by naturally, the knowledge will be able to use spontaneously. The third hypothesis is Monitor Hypothesis. Krashen developed this hypothesis and urged that acquired knowledge is responsible for fluency and intuitive judgements about correctness. On the other hand, learnt knowledge can be put to conscious use through the Monitor. A learner will use the monitor through learnt knowledge to correct and check what they say is grammatically. This monitor operates only under three circumstances when there is sufficient time to self-correct, the focus is on form and knowledge of the rules being applied (Hadley: 1993). The fourth hypothesis is Natural Order Hypothesis where grammatical structures are acquired in a natural and predictable order. It shows the evidence whenever the focus is on communication. The last hypothesis is Affective Filter Hypothesis. Affect refers to things as motives, needs, attitures, and emotional states (Lightbown Spada 1999).This hypothesis is connected to the motivation factor. Cook (1993, cited in Krashen 1985, p.3) claims that in order for a learner to success in acquiring knowledge, CI is a necessary but not sufficient due to a mental block that prevents acquirers from utilizing the CI input they receive for language acquisition This mental block is called affective filter. The affective filter is low when the learners motivation and self-confidence is high as well as low anxiety; therefore, more input is available for acquisition. On the other hand, the affective filter is high when learners motivation and self-confidence are low. In short, the success of acquisition is controlled by the affective filter. Interactionism Krashen claimed that every human has a natural innate mechanism to learn a language along with comprehensible input (CI). However, Krashens CI came under challenge by few Applied Linguists namely Evelyn Hatch, Teresa Pica and Michael Long. Michael Long agrees with Krashen that CI is important for language acquisition but how input is made comprehensible (Lightbown Spada: 1999). Language develops as a result when interaction occurs between children and other speakers. Every learner has to converse and communicate with others in order to adapt what they have learnt which shows their competence and understanding. Therefore, a learner will develop his/her language ability when they take part in spontaneous interactions rather than straight drills (Nunen 1991). Correspondingly, Language acquisition is an outcome of interaction between the learners mental abilities and the linguistic environment (Rozzana: n.d.). Native speaker provides language input to language learner; meanwhile, language learner produces the language as the product of output through communication. In fact, interactional modifications usually take place when native speaker modify their speech in order to make their speech comprehensible. It is supported by Long (p.342) that modification is the vital and widely used method of making input comprehensible. Learners will be promoted and engaged into this modification and negotiation of meaning when there is a communication breakdown. There are few examples of interactional modifications which are comprehension checks, clarification requests, confirmation checks, self repetition/paraphrase and use of extralinguistic features. In addition, learners usually engage in learning when information is to be exchanged with each other. During the process of exchanging information or feedback after the conversation, output will be a route to language learning along with interactional modification. Besides that, two-way communication promotes more interactional modification than one-way communication. According to Rozzana (n.d.), for the learner to communicate, he must learn the language and in order to learn it he must communicate. This point often overlooked on how Bangladeshi workers in Malaysia can master simple Bahasa Malaysia although without attending formal tutorial. They acquire the language through social interaction in daily conversation; also, interact with the environment. Henceforth, Longs ideas are identical with Vygotskys theory of Zone of Proximal Development (ZPD) where learners acquire knowledge through interaction with the physical world (Lightbown Spada: 1999). Comprehension Output Both Michael Long and Stephen Krashen agree that CI as a source of acquisition. On the contrary, some interactionists argue that CI is not sufficient for language acquisition depends on some factors which cannot account for the whole of acquisition (cf. Long, 1989:10). Learners need to be instilled language development especially grammatical development. Besides that, learners must be pushed or forced to produce comprehensible target language in order for language development to occur. With this in mind, one of the activities which is called read and respond in Myline whereby students are assigned an article to read and given their opinion critically. So, students are not only received input from teachers whereas trigger their LAD while producing language, either spoken or written. Fours ways (reading, listening, writing and speaking) in which output might play a role in the process of second language learning have been proposed (Swain, 1985). Listening and reading could be the compr ehensible inputs different from speaking and writing which are comprehensible outputs. Learners are given the opportunities to test his/her hypothesis about the language through comprehensible output. This is especially so when learner notices a gap in his/her interlanguage system if there is a communication breakdown. Once the learner realize the gap in interlanguage system, he/she is likely to search their own linguistic knowledge for information which might help to close the gap; also, pay attention to relevant input (Swain, 1993). Hence, learner will focus on form and mismatches between input and output which may also provide some of the information a learner needs about what is not permissible in a language (Long, 1996). Last but not least, CI encourages semantic processing but CO encourages syntactic processing. Audio Lingual Method is a wise method to be used to learn a language; however, it is not enough to suit the advancement of language learning nowadays. Since this theory deduced that learning is a mechanical process but it does not account for the creativity evident in ones ability to produce novel utterances and childrens imitation of structures show evidence of almost no innovation (Brown 1987, Demirezen 1988). Students will find it hardly to converse in the target language when they step into the true sense of the world; also, unable to write or create new sentences.

Sustainable Rural Smart Development: The Balancing Act

Sustainable Rural Smart Development: The Balancing Act Regional perspectives are changing the way we approach regional topics, including water planning, open space habitat preservation, economic development, and housing. Emerging issues, such as climate change, renewable energy, and public health, are stepping into the regional planning field[1]. Although land-use and zoning regulations remain at the local level, today regional plans have evolved to address development patterns and land use. Regional development approaches can provide understanding on the dynamics of rural and peri-urban territories, or fringe areas. Many of the standards and principles that are applied to local planning initiatives can be applied also to regional planning and some of them in the opposite direction. For example, consider the possible contributions of location theories, such as the importance of physical proximity in growth mechanisms, in the context of these fringe areas and their development. One such approach to sustainable development in rural and fringe areas is the incorporation of rural smart growth principles and integrated regional planning approaches into Sustainable Rural Smart Development Rural Smart. Rural Smart growth is: Smart, by supporting fostering knowledge transfer and innovation in farming, forestry, and rural areas, skills and promoting resource efficiency and supporting the shift towards a low-carbon and climate-resilient economy in driving economic sectors, by recognizing the role of local expertise and consider how to utilize and develop it, but also by providing incentives for social innovation promoting social inclusion, poverty reduction and economic development; Sustainable, by increasing resource efficiency, maintaining the food, feed and renewables production base, providing environmental public goods, reducing greenhouse gas emissions, enhancing carbon sequestration, and development of renewable energy projects and green infrastructure, safeguard sustainable land management, and restoring, preserving and enhancing ecosystems related to farming and forestry; and Inclusive, by unlocking local potential in promoting food-chain organization, including the processing and marketing of agricultural products, animal welfare and risk management in agriculture, expanding rural economies, growing regional markets and jobs, and broadening opportunities to accompany agricultural innovation and diversification. Rural Smart practices are adapted to specific local contexts with the participation of a broad array of stakeholders residents, businesses, developers, elected officials in decision-making processes concerning the future of their communities. In particular, considering how territorial development is envisioned today the coexistence of different land uses, and coalescence, in certain areas and their associated implications require the adoption of new approaches to development strategies that go beyond the traditional divide between the old and the new. The ASP provides a framework for subsequent subdivision and development lands in the urban fringe as part of a proactive approach applied in early stages of industrial development projects. This framework incorporates approaches to sustainable development including low-impact and cluster development resulting in a higher quality industrial development in connection to a larger community. Additional design guidelines guide development and facilitate higher performance green buildings and operations, green infrastructure, and sustainable design approaches thus encouraging developing efficient industrial facilities and processes that: Systemically optimize material, energy, and water flows throughout industrial supply chains. Maximize productive use of input resources and by-products, waste is non-productive. Minimize impacts on the environment by moving toward zero waste and emissions. Integrate sustainable design in facilities and sites. Utilize clean production and eco-efficient technologies and processes. Maximize use of renewable energy systems and sustainably produced feedstocks. Establish the business relationships to share amenities and facilities. This approach to industrial development yields a triple tier of benefits for: Business Greater resource efficiency equals decreased operating costs. Enhanced competitiveness and potential for revenue generation. Increased return on capital investments and asset value. Energy security and independence. Stronger connections with suppliers, customers, and community. Access to eco-product markets capitalizes on the growing consumer demand greener products. Reduced future costs to business and community such as clean-up liabilities. Community More sustainable industrial operations and local prosperity creation (business, jobs, and capital). Can strengthen existing business base and enhance recruiting. Reduced long-term infrastructure and operations costs. Reduced emissions resulting in improved community health. Improved community industry relations, quality job creation, and workforce attraction. Enhanced community identity through eco-branding. Strengthens local economy through regionally produced feed stocks, products, and services. Environment Less waste, emissions, and pollution. More efficient use of energy and resources results in higher levels of clean production. Superior performance, goes beyond regulatory thresholds, and can help streamline regulatory processes. Replacement of fossil based energy and materials. Increased use of renewable energy and sustainable materials. Industrial system and supply-chain pollution prevention versus facility-based approach. 1.1 Goals and Objectives The purpose of the East Industrial Hub Area Structure Plan (EIH-ASP) is to identify those lands within the plan area, as shown in Map 1, where multi-lot housing, industry / business or other types of development may be considered. The main goal of the ASP is to provide a policy framework indicating the preferred land uses, road access improvements, and servicing requirements to ensure orderly planning in the area. The ASP outlines sustainable development standards for industrial development and compatible uses in proximity of industrial development consistent with IDP and ASP policies, and the Countys Municipal Development Plan to respond to future subdivision and development proposals. In order to achieve this main goal of providing a framework for orderly, economic, diverse, and sustainable development of land amongst other things that support the benefits for business, community and the environment, this ASP Bylaw sets the following objectives: To describe the land uses for the area, both in general and with respect to specific parts of the area; To describe the density of population proposed for the area, both in general and with respect to specific parts of the area; To outline the general location of major transportation routes and public utilities; To prescribe and regulate for each part of the area the purposes for which land and buildings may be respectively subdivided, developed, and used; To implement the policies of the statutory plans of the County of Vermilion River; and To establish the procedures for making amendments to this Bylaw. The East Industrial Hub Area Structure Plan is partially located within the intermunicipal development plan area with the City of Lloydminster. Each municipality already has a number of supportive policies in place. Therefore, fostering knowledge exchange will support the overall policy harmonization work to balance, as far as possible, the differences between the pace of growth and/or the level of development.

History of Skin Care| Cosmetic Company Analysis History of Skin Care| Cosmetic Company Analysis I. History of Skin Care Skin care is very ancient; it goes back to the prehistoric times where cave women and cave men deployed all their efforts to survive the severe weather conditions as they did not have any of the comfortable solution we benefit from today. Their skin structure was different from our skin, as it was rough enough to defend itself from sun rays and weather conditions. Even though their skin was enabled originally to fight those conditions, the prehistoric human was aware of certain skin care needs. Skincare the Ancient Civilizations Skin care for the prehistoric human was mainly associated with the relief of pain caused by severe weather conditions and sun exposure. The kind food they were eating was also one of the key causes of skin disease, as they were consuming fatty food that causes acne and skin inflammation. Human body has an impressive natural resistance and skin is considered very elastic having several layers. Human skin is greatly affected by environmental conditions; one can develop a layer of hard skin and get a tan but this process actually weaken skin barriers and decline its condition. The skin the largest organ in the human body and the most exposed to external conditions, as when it changes due to bad conditions it looses its elasticity and develop wrinkles, acne, spots and other symptoms. This is the reason why skin care is very ancient. The history of skin care in the ancient ages, show that the development of skin care remedies is related to the protection required during work performed by mankind. For example the farmers and fishermen have used skin care frequently in their history. Apparently the kind of job they were performing was inevitably exposing their skin to severe weather conditions. It was essential for these workers to preserve their skin against the environmental conditions. So the skin care products were invented to support the daily work life. Actually, it is very difficult to identify the precise time or year of skin care history. But scientist and researchers do have some information that let them determine that skincare dates back thousands of years. When we think about skin care, we generally think about the past fifty years. However, skin care has been around for thousands of years, dating back to the Ancient Egyptians. Skin care has been viewed throughout history as a compliment to beauty and hygiene. The Egyptians The human interest for beauty and appearance has been studied for thousands of years. The ancient Egyptians constitute one of the first civilizations to develop advanced skincare remedies. Researchers found that the first anti-aging methods that approached the skin from a beautifying and well being angle rather than just protection and maintenance were created in Cleopatras age. Cleopatra is famous for her skin care routine, including sour milk baths and Lactic acid for skin exfoliation. Egyptians accorded a great deal of awareness to beauty and body care and they created treatments to maintain their skin health and beauty. In Ancient Greece Beauty was identified by nudity. Greek athletes took regularly olive oil baths and powdered their bodies with sand to balance bodys temperature with the heat and also to protect their bodies from the sun (to prevent it from aging). Women as well as men moisturize their bodies with honey and olive oil to improve their skin health and appearance. Ancient Roman Hair removal was common not only for women but also among roman men. The Romans developed new methods of shaving. Beauty for them was strictly related to skin cleanness. The Romans lived in a water-rich area and took lots of baths to cleanse the skin, removing dirt and oil, and leaving it smooth. Scented oils that they extracted from plants and flowers were then applied to the skin. Bathing was the most important beauty routine for the Romans who related skin health and well being to cleanness. Beauty Hygiene Evolution Beauty and hygiene finished products began to emerge in the late nineteenth century, beginning with antiperspirants and deodorants. From the 1910s to the 1950s, a more regimented program was developed and women began exercise, diet, along with the use of cosmetics, makeup, hair, and body products. During the World War I, women learned to become independent both socially and economically. Women became part of the working class and were able to purchase more and more beauty products. During this time, Hollywood stars looks became desirable and women began to copy the looks of their favourite actresses. In the 1950s when TV became available in almost every home, advertisements were created. Sponsors of major corporations began to support TV shows and the radio. Today, the beauty industry is increasing sales significantly each year. Although ancient civilisations didnt have our technology at their fingertips, they were able to create clever, though sometimes dangerous, beauty concoctions. Nail polish originated in China around 3,000 B.C. The Chinese painted their nails with a polish made of gum arabic, egg whites, gelatin and beeswax. Ancient Egyptians made soap, soaked in milk baths to soften their skin, exfoliated with a mixture of crushed pumice stones and water and moisturized with olive oil. During this time, Egyptians also experimented with dramatic eye makeup. They smeared colorful malachite and galena over their faces and rimmed their eyes in kohl. Kohl was a paste of soot, animal fat and lead. Lead was used in cosmetics for hundreds of years. Ancient Greeks slathered lead all over their faces to whiten skin and clear blemishes. Centuries passed before people learned that lead is a dangerous ingredient with devastating side effects. Documented complications ranged from scarring to infertility to madness. FDA Regulatory The American Medical Association published â€Å"Three Cases of Lead Palsy from the Use of a Cosmetic Called Lairds Bloom of Youth.† This case study paved the way for the formation of the Food and Drug Administration (FDA) in 1906. Three decades later, Ruth DeForest Lamb, the FDAs chief education officer, published a book that documented the serious complications from beauty products. This prompted the passing of the Food, Drug and Cosmetics Act in 1938, putting cosmetics and medical devices under the FDAs control. Beauty pioneers, 1907 to 1950s At the turn of the century, the beauty industry boomed. Many of the popular companies and best-selling products of today first launched during these years. 1907: French chemist Eugene Schueller creates the first safe commercial hair dye and forms LOreal. 1909: Max Factor, often called the father of modern makeup, opens his first store in the theatre district in Los Angeles. 1910: Elizabeth Arden Salon opens on Fifth Avenue in New York City. In co-creating her signature face cream with a chemist, Elizabeth Arden (whose real name is Florence Nightingale Graham) revolutionizes the beauty industry. Science-based skincare becomes the standard, and the modern day spa is introduced. 1914: Max Factor perfects the first type of makeup for film — a â€Å"thinner greasepaint in cream form, packaged in a jar and created in 12 precisely graduated shades,† according to Procter Gamble. 1917: Maybelline founder T.L. Williams launches the first modern mascara after getting the idea from his sister Maybel. 1920s: Eyebrow pencils become popular, thanks to Hollywood star Greta Garbo. The new ingredient, hydrogenated cottonseed oil, helps the pencil glide on more easily. 1932: Brothers Charles and Joseph Revlon and chemist Charles Lachman create Revlon and launch a new kind of nail enamel. 1936: LOreals founder Schueller invents sunscreen. 1944: Miami pharmacist Benjamin Green develops sunscreen for soldiers fighting in World War II. The formula becomes Coppertone Suntan Cream. 1950s: Max Factor introduces the modern-day mascara with a tube and wand applicator. Hazel Bishop creates the first long-lasting lipstick. Skincare Today Moving into the era of Anti-aging has begun with the Baby Boomers generation who are concerned with preventing the aging process. This trend has become so popular, both men and women begun to give a lot of attention to their looks and begun to look for solutions to stop the aging clock. Plastic Surgery, the most sought after solution for both women and men, has become the biggest industry in anti-aging. Even the Plastic surgery industry is changing by moving away from more invasive procedures, such as face lifts and moving to less invasive treatments, such as injectable fillers. Because these â€Å"non-invasive† treatments are available, more and more men and women beginning with the Baby boomers into the Generations X and Y are heading into Plastic surgeons offices to look and feel younger. Laser treatments, Botox, Dysport, huyoluranic acid, restalyne that are injectable fillers are becoming the newest and greatest treatments available among billions of men and women from the 20s and up. Baby Boomers created this trend and the twenty-somethings are beginning to catch on and follow in their footsteps by preventing aging before it even begins. Physicians have been involved in creating some of the most innovative skin care solutions in the last ten years. As we move into the era of Anti-aging, Men and women are concerned with aging and their appearance. More people are looking for advanced skin care solutions. Skin care products with breakthrough ingredients are being sought after. Skin care products are developed to help prevent and heal and protect the skin from sun damage, pigmentation, fine lines, and wrinkles. If we look back throughout history we see that our ancestors have used skincare products on their faces and bodies in their purest forms. Nevertheless newer skin care products are being developed with breakthrough formulas and have very strong claims for preventing and correcting sings of aging. Today, we use some of the same skin care regimens as our ancient ancestors once did, meanwhile technology and scientific research introduced a new era of beauty. Some skincare products still use available fruits, vegetables, dairy products and fats that have been ancient secrets of hygiene, sun protection and anti-aging for thousands of centuries. Even looking back at our mothers and grandmothers skin care regimen was so simple but made a difference in our skins appearance. Egg whites in the hair and cucumbers on the eyes these ingredients appeared in skin care creams, lotions and cleansers for aging skin care programs. Skin care has been used throughout history to help achieve beauty, hygiene and maintain an attractive appearance. II. Current and Future Analyses Cosmetic Toiletries Market Background In the last decade, the cosmetics market has established a very good position and received a lot of attention around the world. The market targets consumers that are spending more and more on their appearances and skin health. The global Cosmetic Toiletries industry is currently worth $190bn, according to Euromonitors 2008 ‘Cosmetic and Toiletries World Report. This Market can be divided into five segments depending on the products use: SKINCARE: Including ‘Hand Body Care: Lotions and mosturizers and ‘Facial care: Moisturizers, cleaners, toners, Anti-aging products, etc MAKE-UP: lipsticks, lip glosses, mascaras, foundations, eye shadows etc. HYGIENE: Soaps Shower gels, deodorant, etc HAIRCARE FRAGRANCES Federal Food, Drug, and Cosmetic FDA defines cosmetics as articles intended to be applied to the human body for cleansing, beautifying, promoting attractiveness, or altering the appearance without affecting the bodys structure or functions. This definition includes skin-care creams, lotions, powders, sprays, perfumes, lipsticks, fingernail polishes, eye and facial makeup, permanent waves, hair colors, deodorants, baby products, bath oils, bubble baths and mouthwashes, as well as any material intended for use as a component of a cosmetic product. The global cosmetics industry has a comprehensive structural growth than that of other consumer products. It aims to meet two needs: 1-the essentials (the basic hygiene) and 2-the superfluous (makeup, skincare, perfumes ). However, it is characterized by a constant rise in innovation, a promotional rate increased by signs and a continuous recruitment and consumers volatile.

Beauty care brands such as Schwarzkopf for hair care and Diadermine for skincare. Turnover: 2.972 Billionâ‚ ¬ Top 20 Groups on the Cosmetic Toiletries Market in 2008 U.S. Beauty Industry Having a year of recession in the US, the beauty market witnessed a decline in all its categories. According to research from NPD Group, Total US prestige beauty sales fell by 8% to 2.9bn in 2009 (January Through May) versus the same period in 2008. The Prestige beauty sales were the most affected by the current climate with 3.3 drop in sales in 2008. This decline is the first one posted by the research Group since 1997. Prestige Make-up and skincare sales were each down by 7% in this period. Even the skincare category that was showing a stable growth showed an important change with the crisis. This decline id the premium-priced skincare sales, affected the growth of the prestige market that has been significantly impacted and witnessed the first year of decline. Meanwhile private labels shares of the Cosmetic Toiletries market grew from 2% in 2007 to 3% in 2008 according to Euromonitor. This growth was driven primarily by the appeal of lower priced products, since private label products are usually priced at least 20% lower than prestige brands. Growth was also driven by retailers, especially drug stores chains, which are introducing higher quality products with more affordable prices. The luxury brands took action to change their strategies in order to fit to the current climate and make better sales. These brands have been highlighting the value approach above everything else; since consumers need to know that they are receiving real value for their spending has been more critical than ever. The actions conducted by beauty companies were not necessarily related to discounting. They have been re-evaluating the whole concept of the total value including the quality of the product, the packaging and the total shopping experience. With the new customers scientism it was essential for brands to raise their products values. The Strategies adopted to provide a better value for customers were concentrated on higher quality products, better services, pampering and a providing the consumers with a real understanding of the benefits they are offering. One of the obvious changed was seen also in the communications strategies of beauty brands, as they have reduced their advertising budgets in traditional media in favour of online campaigns. A rise in internet beauty sales has prompted this shift. PG for example, cut overall US media spending by 18% in the first quarter of 2008 according to TNS Media Intelligence data group, reducing its TV advertising budget by around 30%. On the other hand spending on the internet ads was tripled representing 4% of the groups total advertising budget. In this context social networking sites such as Twitter have taken a new importance, as for example MAC began using Twitter to send updates on backstage New Yorks Fashion Week. Other strategies include reaching out to beauty bloggers that are gaining more and more consumers trust and are representing a big buying influence. Evidently, CT sales in the US are unlikely to show growth as previous years. Euromonitor predicts a decline of 3% inconstant value sales between 2008 and 2013. However US consumers are preparing to spending more on beauty purchases that give them a real value for their money. The economy will recover soon, and beauty brands must set up new strategies to regain their positions in the beauty market. U.S. CT Sales in 2008 By Category $bn Category Sales $bn %Change 08/07 Haircare 10.24 -1.9 Makeup 8.82 -0.6 Skincare 8.30 +1.1 Oralcare 6.09 +0.9 Fragrances 5.57 -5.2 Other 15.59 N/A Total 52.14 -0.1 Source: Euromonitor While most of CT categories showed a decline, skincare was the only category that sustained a growth with +1.1% comparing to 2008. Skincare constitute the largest category in term of the US beauty sales. With 26.4%, of the overall US beauty sales, the skincare category has a promising future with the increasing importance consumers are according to their skin health. Europe Beauty Industry Due to the current economic Climate, 2008 has been a difficult year for the European beauty market. The European Cosmetic Association released the 2008 figures last May. The report data was consolidated by Euromonitor international and cover all 27 EU member stated. The western European market maintained its leading position in 2008, followed by Asia-Pacific and North America. Brazil had the biggest growth followed by Eastern Europe. Total sales for EU plus Switzerland and Norway reached â‚ ¬70bn ($103bn). The absence of growth is attributed to the drop in sales in the fourth quarter. Overall the decrease in Western European countries was compensated by the increase in Eastern EU countries especially Russia, Bulgaria and Romania. European CT Market Annual Growth In term of Volume, the top 5 are the same as 2007: Germany 17.9%, France 14.8%, UK 13%, Italy 12.9% and Sapin 11.1 accounting for 70% of the market. Germany is still the most lucrative market, with sales close to â‚ ¬13bn and 2% growth. Makeup segments grew the most, with a special success of natural products especially mineral based. German consumers tend to pay a lot of attention to ingredients. In France, the market only grew by 0.5%. Private labels contributed to keep a stable consumption. The UK market showed a great resilience to the current economic crisis. Sales of fragrances went up 11% and makeup up 9%. In Italy, the growth was 1%. Makeup was the best category at +3%. In term of chanels Italian consumers tend to favour chemists and direct sellers. In Spain, sales went down by 1.1% as a result of the crisis. Private Labels showed the best performance. Consumers spending show a different top 5: with 235 euros/per capita, Norway is still the number one market, followed by Switzerland 222, Denmark 187, Spain 171 and Austria 168. The European average stayed at 124 euros. European CT Market 2008 Sales by Country All Categories Dropped All five CT categories recorded a sharp slowdown in their growth in comparison with 2007: Fragrances plunged from + 4.8% to +0.4%, Make-up down from +6.7% to +2.3%, Skincare was the most affected by the crisis and dropped from +5.1% to -0.7% Hair care also went from +1.5% to -0.9%, Toiletries plunged from +4% to +0.5%. With the average total Europe fell from +3.8% to +0.1% Colipa cites the good sales in Romania, Bulgaria, Denmark and Spain, which compensated for the weaker figures in western countries such as the UK, France and Germany. Skincare remained the leading category representing 25.8% of the total sales. Toiletries came second with 24.4%, followed by haircare 22.2%, fragrances 15.3% and makeup 12.4%. Change in European Markets by Product Category (%08/07) Skincare Market Structure Skin care is a dynamic, rapidly evolving fragmented market with well established players, some good marketers, old companies, and new ventures. Consumers are well informed and demanding new products which offer more than just the functional benefits. Sensory and emotional features also play a very important role in the total product package. Baby boomers are still the core consumers, but the next generation in their 40s and beauty obsessed youth are also great potential customers for skin care industry. Product innovation is the driving force and the differentiation between mass market and premium category is becoming vague. Besides traditional retailer market supermarket, drug store and mass merchandise, skin care products are now also sold through professional channels like spas, dermatologists office, and plastic surgery clinics. According to Federal Food, Drug, and Cosmetic (FDC) Act, cosmetics and their ingredients are not required to undergo approval before they are sold to the public. Skin care product sales by mass marketers are increasing especially with the development of new products that claim to have same benefits of premium products with affordable prices. Department stores account are losing market share to other retailers such as drug stores, and professional circuits where sales of skin care products are significantly increasing. The Skincare Industry Segments Natural: there is no actual definition of natural. All ingredients are chemicals by definition. Derived ingredients are unnatural both according to the original substance and the method of derivation. Organic certified: an independent party guarantee of an organic claim. Certified organic products must contain a minimum of 95% organic ingredients excluding water and salt/minerals, with a small allowance for natural, non-organic ingredients that must comply with very rigorous processing criteria. Professional skin care brands: dermatological and clinical brands sold in outlets such as spas, dermatologists offices, plastic surgery clinics, and other professional channels. Cosmeceuticals Nutraceuticals: The term â€Å"cosmeceutical† was introduced for the first time by the dermatological professor Albert Kligman in the late 70s, to describe agent that are applied to the skin that are more active than cosmetics but not so active that they have uncomfortable or harmful side effects. Cosmeceuticals are the hybrids products between cosmetics and drugs, for topical application S. Cosmeceutical products are formulated with biologically active ingredients claiming to have medical or drug-like benefits. This market was initialised in the United States by dermatological doctors like Dr. Perricone and Dr. Murad who declinated their formulas through their own brands. At present the term has no regulatory standing, and the FDA does not recognize it, therefore these products do not need any form of additional regulatory. It is used more in a marketing context to highlight formulations or ingredients that claim to have perceptible effects on the skins structure and appearance. â€Å"Nutraceuticals† is emerging in the form of nutraceuticals-products taken internally in order to obtain an external skin care benefit. Because the skin is such an efficient barrier, and its upper layer has no blood supply, its difficult to get nutrients and other vital materials from the skins surface down into the deeper layer of the epidermis, where the cells are nourished. That is why nutraceuticals are vital to complete the role of topical application as they nourish the skin from within. The Skincare Market Metrics The global skin care market constitutes that largest category in the Cosmetic and Toiletries industry and is predicted to show 7% annual growth according to data from Euromonitor International. This market is driven by an aging population, growing consumer prosperity and the increasing importance of the emerging markets, according to a report by Global Industry Analysts. Skin care market shows a significant growth, mainly due to growth of anti aging products. Currently anti-aging products are the first category in sales and Hand body is expected to be second largest after that. Europe and U.S. represent the largest regions in global skincare market. Asia pacific is an important market for skin care. Japan has a large and affluent market, with beauty routines involving 5 or more steps in comparison to North American or European women who use a 3 step regimen. China is the second largest market in the region. Skin care is the largest category in the global CT market and it maintains a stable growth rates with a fluctuation due to the economic crisis. With sales up 6.8% in the overall market, facial skin care is the most profitable, but we are also seeing manufacturers such as LOreal and PG extending their facial brands to other parts of the body as the hand and body care is stating an important growth. Firming/anti-cellulite body care enjoyed growth of approximately 9.5% in 2008, making it the worlds most dynamic skin care sector and pinpointing to a growing consumer obsession with body-focused skin care. Other factors fueling skin cares growth in 2008 are the continued obsession with anti-aging products and Mens skin care. Skin care continues to be a core category. Skin care industry market retailing is confronted with changes in product segment, market segmentation, consumer preference and taste changes etc. Research and development are driving the creation of new generation of high-tech, innovative products. New technology, especially Internet, is providing new marketing tools for promotion and sale of skin care products. The Anti Aging Segment On a worldwide dynamic skincare market we do notice in spite of the dynamism that there is an erratic growth depending on the market segment. We notice that the anti aging category represents one of the highest growth rates in the beauty industry. The anti-aging segment is characterized typically into boomers and the youth anti-aging market. These markets vary in terms of products and service, market structure, and positioning. The global population of 200 million boomers is growing at 38%, in comparison with to the population, which is showing a 13% growth. This significant growth is making the boomer population more appealing for anti-aging business. Anti-aging groups are adjusting their strategies while targeting the boomer market, which differs with race, sex, income level, family status, young and old boomers, insurance status, and distribution channels; we see that companies interests in this market is making a big shift in products offers in term of innovation and high technologies that allow them to offer right, proper and effective products for this particular segment.

Assassins Creed in Popular Video Game Culture Essay -- Globalist Agend

Video games have risen in popularity in America the past couple decades where popular gaming franchises influence or reflect modern American culture. Many video game franchises are popular but one franchise that has stood out in video game media is Assassin's Creed. Assassin's Creed is a franchise that consists of video games, spinoffs, comics, graphic novels, animated films, figurines, weapon replicas, clothing, and other merchandise. Only focusing on the video game branch of the franchise, the series began in 2007 with its first installment released. The franchise was planned out as a spin-off for the Prince of Persia series but developed into their own franchise. Currently there are seven main games in the franchise all of which have historical fiction, action-adventure, and stealth genres. The games feature dense narratives, historical buildings with the ability to climb freely on them, and the iconic hidden blade. Since the first game, roughly around 57 million copies of the fr anchise were sold world wide (â€Å"About Ubisoft†). Compared to other popular franchises such as Grant Theft Auto, that sold 150 million, and Halo, that sold 50 million, Assassin's Creed franchise has its fair share of popularity. Not focusing on only statistics, go to any video game convention and you would most likely see people dressed up as assassins or see merchandise of the franchise. So in video game culture now Assassin's Creed seems fairly popular. Considering how popular Assassin's Creed is in America, the game has aspects that reflect common ideas, morals, and traits that are present in American culture as well as other popular American media. The most obvious trend Assassin's Creed has is the violent aspects in the game. Assassin’s Creed is ... ... America, 10 Sep. 2009. Web. 28 Nov. 2013.

Solar Energy May Save the Earth Essays -- Power Environment Global War

Solar Energy May Save the Earth Abstract: The current energy situation with fossil fuels as the main source of the world’s energy has two main flaws: fossil fuels contribute to global warming via the greenhouse effect and they are limited in the quantity that remains. Solar power solves both of these problems and can be captured by utilizing photovoltaic cells. However, photovoltaic cells have their own drawbacks due to their high costs of installation and maintenance. The world currently functions through the use of fossil fuels. However, fossil fuels possess two significant disadvantages. Fossil fuels harm the global environment because they enhance the greenhouse effect by releasing carbon dioxide, and they release other harmful gases such as sulfur dioxide and nitrogen dioxide.1 Also, fossil fuels are limited and will run out in the near future if current rates of consumption are maintained. Photovoltaic cells that convert solar energy to electrical energy solve both of these problems. Although the production of photovoltaic cells causes some pollution, photovoltaic cells do not emit harmful gases nor do they pollute the environment. Solar energy is virtually unlimited since the Sun will continue its fusion reaction and provide light energy to the Earth. Solar energy cannot be absorbed on dark or cloudy days, but if it can be stored, solar energy gathered from luminous periods can be used during those dim days. Photovoltaic cells have an estimated lifetime of approximately 20 years and if 100-watt photovoltaic cells are used, they will produce an equivalent amount of energy as fossil fuels that will create two tons of carbon dioxide as a byproduct.2 At a superficial glance, solar power seems very promising since the sun p... ...gy. â€Å"Solar Energy Technologies Program.† 22 May 2008. 4.

Subnet Masking And Addressing :: essays research papers

Ok, this explains subnet addressing which is useful if you run a scanner, a firewall, a router or anything else that is bound to IP subnet addressing. Note that this only describes IPv4 subnets. Reading binary values Normally, you read binary numbers bytewise (8 bit wise). Start at the last bit, bit 0. If it is 1, add 2^0 to your number, else add 0. Then the next bit, bit 1, If it is 1, add 2^1 (2) to your number, If bit 3 is 1 add 2^2 (4) to your number, if bit 4 is 1 add 2^3 (8) to your number ... if bit 8 is 1 add 2^7 (128) to your number. You see, the base is always 2 because it can be either 0 or 1. Example 1: 10100100 = 2^7+0+2^5+0+0+0+2^2+0+0 = 164 Example 2: 11111111 = 2^7+2^6+2^5+2^4+2^3+2^2+2^1+2^0 = 255 Thats it! Now to subnet addressing. When you state a host including a subnet (example: nmap), you do it like this: 1.2.3.4/24, where /24 is the subnet. Lets have a look at what this means: an IP address is a 32 bit address. It is divided into 4 bytes (each 8 bits meaning they can be 0 to 255) in general notation: 00000001 00000010 00000011 00000100 = "1.2.3.4" now, IP uses one part of this address to specify which Net it is on. Most of the time, this is a physical Net like an ethernet LAN that is linked to the internet. Nets that link to the internet get dedicated IPs for each of their hosts from the IANA.org. /24 means that the first 24 bits are the Net address and the remaining 8 bits are the Host address. This looks like this: Net: 000000010000001000000011 Host: 00000100 Meaning, we are on the net 1.2.3.0 (0 used as a wildcard here) and on the host 4 of 256. SUBNET MASK: In this case, the subnet mask would be 255.255.255.0. A subnet mask is created simply by filling all NET address bits with 1 and the HOST bits with 0. (11111111 = 255). There are 4 "Classes" on the Internet, which are the standard Subnets. *Class A: "0" + 7 net bits + 24 host bits, hosts 0.0.0.0 to 126.255.255.255 Net IDs: 0 0000000 to 0 1111111 (which is 127 => 127.0.0.0 reserved for local loopback) *Class B: "10" + 14 net bits + 14 host bits, hosts 128.

Compaction of Concrete

Consolidation of plastic concrete is termed as compaction. In the process of compaction, efforts are only directed to reduce the voids in the compacted concrete. Compaction of concrete can be done either manually or mechanically. When it is done manually it is called hand compaction or tamping, and in second case it is termed as machine compaction. ?Hand compaction: Hand compaction is done with the help of steel tamping rods, or timber screeds. Marrow and deep members are compacted with tamping rods. Thin slabs and floors are tamped with the help of screeds.Compaction should be done in layers of 30 cm for mass concrete and 15 cm for reinforced concrete. Companction should be carried out for such a time that a layer of mortar starts appearing at the compacted surface. Excessive compaction and under compaction both are harmful for concrete. Due to excessive compaction, C. A. particles sink to the bottom and cement and F. A. mortar appears at the top. This makes concrete structure heter ogeneous, and hence affects strength. This method of curing is adopted in the case of precast members.It has been noticed that by keeping the wet conditions, if temperature is increased, the rate of increase of strength also increases. This enables concrete to acquire its full strength within short period and hence, curing is also finished within short period. ?Machine compaction: Machine or mechanical compaction of concrete is done with the help of vibrators. Vibrators produce vibrations which when transmitted to plastic concrete make it to flow and affect compaction. The air bubbles are forced out of concrete due to vibrations. Over vibration should not be allowed, otherwise C.A. particles will concentrate at the lower layers and mortar will come to the surface. There are three types of vibrators in most common use: †¢Internal vibrator: This vibrator is also known as immersion, poker, or needle vibrator. It consists of a power unit and a long flexible tube at the end of which a vibrating head is attached. This vibrator develops about 7000 vibrations per minute. Wherever, compaction is to be done, the vibrating head is inserted in the concrete. This vibrator is very useful for compaction of mass concrete. †¢Form vibrator: This vibrator is clamped to he form-work and imparts vibrations to the concrete through form-work. This vibrator is used only if the use of internal vibrator is not practicable as in the case of thin and congested situations. It is also called external vibrator. †¢Surface vibrator: It is also named as screed or pan vibrator. It is clamped to the screed, it Imparts vibration to the concrete from the surface when screeding operation of the concrete is carried out. It is effective only for depths of about 20 cm and hence useful for thin horizontal surface such as pavements. Compaction of Concrete Consolidation of plastic concrete is termed as compaction.

Job Design at Pepperdine University Essay

This case study primarily focuses on the dimensions of specific roles for Pepperdine University employees. The aspect of job analysis or job reviews is an overall exploration of specific responsibilities accountabilities and duties of specific jobs. This is quite a lengthy process that requires the gathering of background information and the creation of a job specifications and descriptions. This case study highlights the roles of several employees at the Graziadio School of Business and Management at the Pepperdine University. Job design There is no definite job design that can be clearly identified at the Graziadio School of Business and Management therefore most of the observations can only be inferred from obervation of employee duties and responsibilities(Cummings & Worley, 2009). Job design is supposed to determine the manner in which specific jobs are supposed to be carried out and how this ultimately affects the individuals worker as well as the overall work place. This includes aspects such as employee authority, processes of decision making, amount of respnsibility among other criteria. It was noticed in the case study that there were three jobs that would be categorized in the same job design group and these were the program administrator, the administrative assistant and the faculty director. The roles of employees in these positions have distinct job descriptions but from their duties it is clear that they are interdependent. Another issue that is dealt with in this case study is that of employee rewards. From the example in the test, the university clearly appreciated the diligence and loyalty of the Program Administrator and for this he was to be rewarded through the enrichment of his current position. The job enrichment was partly due to the personal character of the Program Administrator because he was able to exhibit diligence and patience for 15 years. Assesment of an  employee’s persoanality is therefore key when an organization is considering formulating a formal job design model. Skill appraisal In the case of the Program Administrator, it was evident that the specific duries were very varied in nature ranging from student recruitment and supervision to advisory roles. Other aspects in this analysis include the assesment of task identity, task significance as well as job autonomy (Cummings & Worley, 2009). Planning and implementation The planning of this study was quite thorough and widely encompassing. There was a great deal of assesment and also use of diagnostic models which were associated with individuals and groups. All the models that were used were carefully structured and diagnostic in nature. They included the issues to do with design components, inputs, and output of both individual and group job specifications. The reason was doing group diagnostic was deemed necessary is because the organizational make-up is considered as a primary input that needs to be properly examined. This brings out the functions of group dynamics. However, to bring out the individual aspect of the study, the plan included an individual job level assesment to offer infomation regarding issues like individual task significance, task autonomy, identity and all the feedback that can be achieved from all this collective data. Overall the planning of the case can be considered quite thorough. Reference Cummings, T, Worley Christopher. (2009). Organizational Development & Change. South-Western CENGAGE learning, 9th Edition
