Education Regulation Law - Research Paper Example It is evidently clear from the discussion that not attending school leads to poor academic performance and lack of educational success, both contributing factors when discussing juvenile delinquency, an issue that is becoming more and more prevalent as time goes on. Many factors exist as to why a juvenile will not or does not attend school. Perhaps a juvenile has failed to bond at school, has no friends or reliable relationships among his or her peers (Flores, 2003). A juvenile that does not have any friendships among their peers, or feels isolated and alone, will often choose not to go to school, and thus jeopardize their chances of educational success. In young children aged eight to eleven, poor academic performance has been related to serious later delinquency (Flores, 2003). Another contributing factor to failed bonding is the fact that not attending school leads to poor socialization, and thus the feeling of isolation deepens even more. Students who are chronic underachievers t end to be the most at-risk group for juvenile delinquency (Seigel & Welsh, 2010). In all of these situations, a juvenile will most likely choose not to attend school, instead of finding something else to do with their time. The actions that they choose could well lead them down the path of juvenile delinquency. Education has been widely promoted by all sources surrounding juveniles, from family to the media to the schools themselves (Seigel & Welsh, 2010). Most juveniles have been trained to accept the fact that education itself holds the keys to success, whether that success is measured in a better job, more money, or a better way of life (Seigel & Welsh, 2010). However, many juveniles may feel that they do not meet the acceptable standards for educational success, whether that success is measured in test scores, promotions, rewards, or other measures (Seigel & Welsh, 2010). In measuring themselves, often juveniles are their own worst critics, feeling that they will never be good a t anything; therefore school and education are a waste of time. They feel that this time could be better spent learning â€Å"life skills†, skills that all too often lead to a life of juvenile delinquency. No matter what the forces are behind a juvenile feeling as though education will not be of any use to them at all, it is clear that early intervention is necessary to determine who and where the most at-risk youth are. Oddly enough, the first intervention taking place in school may already be too late for some juveniles. It has been shown that parents have a vital role in the success of their offspring, and positive relationships between family members only serve to heighten the chances of educational success (Adedokun & Balschweid, 2008). If an early intervention takes place and identifies possible situations that may not be of benefit to a juvenile, measures can be taken such as family counseling and other assistance that may promote and save the educational career of a j uvenile and prevent them from starting any form of juvenile delinquency. Another important factor of note is the juvenile themselves. All juveniles do not learn the same way; just as adults do not all enjoy the same hobby or pastime. To expect every juvenile to learn the same way, by sitting in a classroom and listening to a lecture, may be expecting too much.  

Fingerprinting Research Paper Example | Topics and Well Written Essays - 250 words

Fingerprinting - Research Paper Example It is an excellent way of tying a suspect to a crime scene. There are different types of fingerprints found by investigators. Some are visible and some are latent. Visible prints are those taken from a suspect usually using ink. They are clear and whole. Latent prints are usually left accidentally and may only be partial. They may not be visible to the eye and may require dusting. Fingerprints in the past were largely classified by ridge formation. Loops, whorls, and arches on a fingerprint were also used to distinguish various prints from one another. Fingerprints are now generally photographed and kept in a digital database. This makes them much easier to access. New fingerprints can be scanned in. Fingerprints are still a useful form of evidence, but they are not as determinative as DNA. They are especially useful in showing where people have been and what they have done, while DNA (in some cases) may simply put a person at the scene of a crime. Fingerprints may be considered more

Gillette Essay Case Analysis for Gillette: Product and Marketing Innovation 9/11/2012 Abstract Gillette is seeking means to retain dominance in market share they have lead for the last century. Along with sustaining market share Gillette has continued focus on expanding worldwide into less saturated markets. In this analysis multiple alternatives will be explored in order to make a recommendation on steps that would favor Gillette’s organization in meeting their aspirations. Situation Analysis Product quality and efficient marketing are the core value propositions that set the pace for Gillette’s success. With continued innovation in both product development and marketing strategies Gillette has been able to retain a commanding worldwide market share in a highly competitive, but mature, razor and blade market. Strong market share allowed Gillette to sustain profits even through economic droughts in recent years. On the flip side, Gillette’s innovation success also posed challenges. In order to maintain their market share, a dependency on continuous product improvement formed over time. Now Gillette will need to determine how to balance investment in research and development along with other areas of the organization. At times their own innovation of new product lines impacted their leading product lines in the market. During the 1990s Gillette found themselves cannibalizing their own successful products when trying to out due the competition. Even though internal competition shifted sales from one product line to another, Gillette’s sales were able to re-coop development costs. Expanding market share around the world also revealed challenges with varying religious and culture beliefs. Western influences have started to generate growth with European woman as younger generations watch American movies and television that depict women with sleek underarms and legs. Gillette’s latest innovation, the Fusion 5(+1) blade, was back in 2006. Since then Schick, Gillette’s leading competitor has not responded with their own break through. Gillette should be wondering what Schick might do next. Problem As the market Gillette has lead for so long became mature, their growth ultimately declined due to market saturation and increase competition. Fluctuations occurred only when newer, more innovative products were introduced. This put more pressure on development advancements and marketing tactics. Many analysts believe that Gillette and Schick, leaders in razors and blades, have reached the end of meaningful product innovation [1]. In 2006 when the Fusion 5(+1) blade was introduced, it exploded off the shelves. Gillette sold more than 4 billion Fusion razors with in the first two months. The Fusion’s initial success was quickly fleeting as sales reports showed that razors were outselling the cartridge refills. This was very concerning to Gillette as it is well-known that razor manufacturers earn most of their profits from refills, not the initial razor purchase. Critics also questioned why five blades were needed to get the best shave when Gillette had touted its three-bladed Mach3 as †the best a man can get. † â€Å"Consumer reports conclude that there were no additional performance benefits provided by the five-bladed Fusion, especially when compared to the Mach3† [1 pg391]. Economic recession also impacted sales as Gillette’s products went up in price due to a need to re-coop development costs. How can Gillette continue to maintain or grow market share in a mature market and keep future strategies aligned with customer wants? Alternatives Continue product line and marketing without major change. No additional research and development costs would need to be spent, which in return reduces the need to raise prices for maintaining their profit margin. However the risk looming would be competitor innovation impacting current market share. Schick may produce a new innovative product that would sway consumers from purchasing Gillette’s products. As stated in the case Gillette must find new ways to innovatively out-produce or out-market the competition. Investing in research and development to create new product line or enhance current products adds considerable expenses. Development costs will need to be re-cooped. This will keep competitors in check, but will be challenging to keep pricing competitive. Compliment current leading product lines that keep consumers happy. Promoting Christmas, Father’s day and Mother’s day gift grooming kits that meets more of the consumer’s needs will also introduce consumers to other product lines Gillette has to offer. Focus marketing potential growth opportunities globally by challenging resistance in product awareness and interests. As a Gillette razor consumer, I have encountered an inconvenience that I think can be solved and build customer loyalty. I’ve been using Mach 3 razors for over fifteen years, and when purchasing refills I have found it difficult to find blades that are compatible with the razor handle that I own. Thinking out of the box, what if Gillette were to make razor handles that are compatible with any of Gillette’s product line of refills? This would then provide consumers the freedom to purchase from a variety of Gillette’s product lines without having to spend extra money on a handle that works with the particular product refill. Owning a Gillette universal handle would also encourage customers to stay with Gillette refills as converting to another brand would cost more with the initial required handle purchase. Implementation From the case I would assume Gillette will continue to â€Å"innovatively out-produce or out-market the competition† [1]. I believe moving forward with developing a universal handle with Gillette refills would accomplish this. This would require investment into developing a new handle and rollout of the product. Here is an approximate timeline to complete.

Properties Of Soil Including Density And Porosity Environmental Sciences Essay

Properties Of Soil Including Density And Porosity Environmental Sciences Essay Experiments were undertaken to obtain the bulk density, particle density, and soil porosity of four soil samples. Bulk density, particle density, and soil porosity are all interrelated terms. Density is the relationship between the mass (m) and volume (V) of a substance. . Based on this relationship, an object or substance that has high mass in relation to its size (or volume) also has a high density (D). Soil bulk density (Db) is a measure of the mass of soil per unit volume (solids + pore space) and is usually reported on an oven-dry basis. The particles that make up a soil have a specific particle density (Dp), which is defined as the mass of solid particles in a unit volume. This can be expressed as, . The particle density of a soil is not affected by particle size or arrangement; rather it depends on the type of solid particles present in the soils. Unlike the measurement of particle density, the bulk density measurement accounts for the spaces between the soil particles (pore s pace) as well as the soil solids. Soils with a high proportion of pore space have lower mass per unit volume, and therefore have low bulk density. A bulk density greater than 1.6 g cm-3 may indicate soil compaction, which means these soils have a low proportion of pore space and, therefore, low porosity. The bulk density indirectly provides a measure of the soil porosity which is the ratio of the volume of soil pores to the total soil volume. Clayey soils generally have an abundance of very small pores that give them a higher total porosity compared to sands, which are dominated by larger, but fewer pores. MATERIALS: 1. Core soil samples 2. Balance (0.1 g precision) 3. Flat-bladed knife 4. Veneer calliper 5. Disturbed soil samples 6. 100 ml measuring cylinder 7. De-aired water METHOD: The bulk density of the soil was calculated after following a series of steps. Firstly, excess soil from each of the disturbed soil sample was removed using a flat-bladed knife, ensuring that the bottom of the sample was flat and even with the edges of the ring. Excess material or roots penetrating from the sample was cut using a scissors. The dimensions of the core were then measured using a veneer calliper and the dimensions obtained were plugged into the formula Volume= à Ã¢â€š ¬ * radius 2* height to calculate the volume of the core. This value was then used to obtain the bulk density of the soil (Db = ). Afterwards, approximately 50g of soil was weighed out in a weigh dish for each soil sample and the soil weight was recorded to the nearest 0.1 g. e 50 cm of water was then poured into a 100 ml graduated cylinder and the previously weighed soil was added into the water in small increments. Air bubbles were eliminated by stirring with a rod and the final volume of the soil water suspension was read and the value was recorded. This value was then used to calculate the particle density of each soil sample (Dp = ). Using the measured densities the percentage soil porosity was calculated via the formula, 100-( Db / Dp * 100). Data was recorded and presented in a tabular format. RESULTS: SOIL SAMPLE HEIGHT OF CORE (cm) DIAMETER OF CORE (cm) VOLUME OF CORE SAMPLER (cm3) 1 5.548 5.36 125.2 2 3.862 5.58 94.5 3 4.889 5.858 131.8 4 4.798 5.384 109.2 FIGURE 1: TABLE SHOWING THE HEIGHT, DIAMETER AND VOLUME OF THE CORE SAMPLER FOR EACH SOIL SAMPLE.

To calculate how many grams of soil are in a hectare plow layer: Depth = 15cm =0.15m Hectare = 10,000m2 Volume of HPL = Area of Hectare * Depth of plow = 10,000 * 0.15 = 1500m3 Db = 1.4g/cm3 = 1kg = 1000g à ¢Ã‹â€ Ã‚ ´1400kg=1400 ÃÆ'-1,000 = 1,400,000g Therefore, there are 1,400,000g of soil in a hectare plow layer. DISCUSSION: Soil porosity and bulk density are interrelated terms. Soil bulk density (Db) is a measure of the mass of soil per unit volume while soil porosity is the ratio of the volume of soil pores to the total soil volume. Bulk density (Db) is closely related to the soil porosity through the following relationship:. The bulk density indirectly provides a measure of the soil porosity (amount of pore space). The value obtained from the measurement of soil bulk density can be used to calculate pore space. For soils with the same particle density, the lower the bulk density, the higher the percent pore space or total porosity. Soil porosity values range from 0 to 1. Soils with a high bulk density have low total porosity because empty pores do not have any mass. When the bulk density is zero, porosity equals 1, meaning there are no particles. If the bulk density is equal to the particle density, then there are no pores and porosity is zero. Soil porosity can be affected by changes occurring in the soil. The porosity of the soil decreases in compacted subsoils and increases in well- aggregated, high organic matter surface soils. The values range from as low as 25% to more than 60% respectively. Soil management can also alter soil porosity values such that, cultivated soils tend to have a lower total pore space as a result of a decrease in organic matter content and a consequent lowering of granulation, in comparison to uncultivated soils. Bulk density and porosity are also affected by changes in soil texture. Fine-textured soils including clay, clay loam and silt loams typically have lower bulk densities as compared to sandy soils, due to the presence of pores between and within the granules. As a result, these fine-textured soils containing a high proportion of pore spaces to solids tend to have low bulk densities. Sandy soils, on the other hand, though larger in particle size have larger yet fewer pore spaces, resulting in a higher bulk density. In terms of porosity, fine-textured soils are very porous. This is because of the large amount of micropores in fine-textures soils which allow water to be held. These micropores prevent the water from being drained away and therefore, result in high total porosity. In contrast, sandy soils have less total porosity due to the relative absence or lack of fine, within-ped pores. This allows water to be drained away easily through the macropores present in sandy soils. Addition ally, bulk density and porosity are affected by changes in the size class of the soil particles. Bulk density is lower in sandy soils or well-sorted sand where the particles are generally of one size class whereas a mixture of different size particles (well-graded sand) will cause a high bulk density. In well-graded sand the smaller particles partially fill in the spaces between the larger particles causing a reduction in the pore spaces and a resultant increase in bulk density. Soil porosity, on the other hand, is decreased in well-graded sand as compared to well-sorted sand. Another factor impacting bulk density and porosity is compaction. Soil compaction refers to the disruption and reduction of the large pores within the soil. It can be caused in a variety of ways such as, the practice of poor agricultural practices, use of machinery on soil, etc. Compaction increases the mass in a given volume, which increases the measured bulk density. Bulk density increases because both the micropores and macropores in a soil are significantly reduced after compaction has taken place. Therefore, with the removal of these empty pores, the mass of soil increases in a given volume. With regards to porosity, compaction reduces the total pore spaces and hence, the total porosity. In conclusion, bulk density and porosity are two interrelated soil properties which are altered by various factors including soil texture, compaction and soil structure. Calculations into the bulk density and porosity were carried out. Some limitations presented were the fact that bulk density and porosity values would differ from place to place due to certain factors, for example, the level of compaction in an area. However, these figures can be useful in determining the crop yield of a soil.

Factors Affecting General Motors

Factors Affecting General Motors Industry involved in the design, development, manufacture, marketing and sale of motor vehicles are known as automotive industry. More than million of motor vehicles, including cars and commercial vehicles were produced worldwide in 2007. Figures show that in 2007, around 71.9 million new automobiles were sold worldwide in which 22.9 m sold in Europe, 21.4 m in Asia-Pacific, 19.4 m in USA and Canada, 4.4 m in Latin America, 2.4 m in the Middle East and 1.4 m in Africa. Though the markets in North America and Japan were inactive but in South America and Asia markets grew very strongly. Russia, Brazil and China were the one who showed rapid growth compare to others. In 2008, automotive industry were experiencing a combination of pricing pressures from raw material cost and changes in consumer buying habits due to rapid rise in the price of oil. G.M and other automotive industries were also facing external competition from the public transport sector, as consumers re-evaluate their private vehicle usage. U.S is the worlds largest consumer market for light vehicles, passenger cars and light trucks which are conquered by big three companies i.e. General Motors, Ford Motors and Daimler/Chrysler. But recently these three industries were started to lose their market share to other rivals within the industry. General Motors are facing huge competition by domestic company such as Ford Motors and Daimler/Chrysler and also by foreign companies such as Toyota Motors and Honda Motors who are able to produce car much cheaper cost than General Motors. In 2006, General Motors has been bankrupted and has been avoiding a filing for years. For years it has been using cars as razors to sell consumers a monthly package of razor blades- in the form of highly profitable car loans. And the reasons for its bankruptcy are because they were focusing mostly on their finance division rather than it vehicle design operation. GM cars were poorly designed and build, took long time to manufacture as compare to its toughest competitor Toyota who has better designed and high quality and cheaper. In past GM controlled half of North America vehicle market but presently it has only 19 percent control as GM has been ignoring competition due to which Toyota and other industry took over the market share. Since General Motors were focusing on making profit from finance they did not care about building better vehicles. It was managing in bubble as GM rewarded those employees who followed the old way of doing things and those who praises CEO wisdom and carry out his orders. PEST Analysis (P)olitical: Since 1960, there were more powerful and strict laws and Government intervention that has affected GM and other car industries. Mostly, all regulation was related to consumer increasing concern for environment and concern for the safer automobiles. (E)conomical: Automobile Industries plays an important role on every countries economy. As Automotive industry are major user of computer chips, aluminium, textiles, copper, steel, iron, lead, plastics, vinyl and rubber. Research and study had shown that for every autoworker there are seven other jobs created in other industry which include aluminium to lead to vinyl. (S)ociocultural: Todays people are mostly concern about their status and society judges on the basis of what type of car one drives. Manufacture takes advantage of this thought and target the market. Every one want attractive and nice car which other people admires. Consumers feel better when they driving nice and new car. (T)echnology: Internet had played a significant role in automotive industry. A study showed that about 60 % buyers referred to internet before making their purchase and out of that 60 percentage. 88 % buyer went to auto website before going and taking test drive. Strength and Weakness of General Motors. Strengths: Huge Market Share: Although General Motors market shares has dropped in United States but it still has very much competitive at 26 percent. On the other hand, it is increasing its share in Chinese market and world wide. They still believes that they have an opportunity to become automotive leader once again as it was before. Global Experience: Although General Motors share have decline recently but they have capability of becoming leader once again due to vast experience of almost 100 years. As GM current opportunity is to expand globally and it has got experience to do so. Variety of Brand names General Motors had been leaders in the past and reason for that is wide variety of quality brand names that differentiate it from other automotive manufacturer. Its current brands include GMC, GM Daewoo, Chevrolet, Pontiac, Saturn, Hummer, Saab, Holden, Buick, Cadillac, Opel, Vauxhall and Wuling. GMAC Customer Finance Program Since, General Motors Acceptance Corporation establishment in 1919, it has proven to be GMs most reliable source of revenue. On Star Satellite technology Star Satellite technology was developed in1996 with a subscriber of more than 3 million and it is the standard of all GM vehicles. The benefit of this technology is that vehicle can be easily tracked at the time of emergency or theft. On the other hand, it allows the driver as well as passengers to communicate with On star personnel just in one click of button. Weaknesses: Behind on Alternative Energy Movement: This is one of the biggest weaknesses of General Motors. The alternative energy/hybrid technology has already taken place in the automotive industry and GM has been one step behind the competition in terms of alternative energy vehicles. As a result, GM faced lots of problem including loss of market shares and fall in company profit. Now days for any automotive company looking for success must be Hybrid friendly and fuel efficient. Poor Organizational Structure: This is the second and significant weaknesses of GM. Its organizational structure seems to be too vertically integrated. As a result, there is lack of communication between top level management and bottom level management and may have played a part in GM falling behind on the alternative energy movement. Stagnant Profitability: General Motors profit has been certainly falling and they are struggling with respect to the size of their company. General Motors profit margin was about 1.5 % and the ROE has dramatically decreasing by dropping to 10 % in 2004. At this situation shareholders are not happy and they are becoming less interested. Fully Based on US market: For any one who is concentrating on one particularr market cant be successful. This is what happened to GMs case, it fully dependent on the US market. It must take advantage of the opportunity to expand globally. Due to high competition, it is becoming too strong to focus on just one country. Over Dependent on General Motors Acceptance Corporation (GMAC) Financing: The other important weakness of General Motors is that it is too dependent on its financing program. Although, it is accepted that it is a great strength for GM, however it will be a problem if it solely rely on financing and cant turn profits, in order to compete with Honda and Toyota who are rapidly growing. Poor Credit Status: GMs credit status is steadily declining same as everything else. It is losing credit in market and amongst the customer. Its current ratio is merely above 1 and its acid test is even lower. Poor strategies and lack of Foresight: Due to increase in oil prices, consumers began to turn away from SUVs, but still General Motors predicted much of its operating success on its ability to sell newly unpopular vehicles. While companies like Toyota, were concentrating on light vehicle and in improving efficiency where GM assumed sales would continue in future. ALTERNATIVE FORMS OF ORGANISATION DEVELOPMENT Organizational Development is a system which differs from other systems of organizational change by putting stress/focusing on process rather than problems. In fact, change system focuses on identifying problems in an organization and then trying to alter the behaviour that creates the problem. OD is a methodology intended for use in complex situations to provide intervention strategy for change management. OD finds the behavioural interactions and the pattern that creates or sustain problem. In fact, OD does not change the behaviours, but they focus on creating a behaviourally healthy organization that will automatically solve and prevents the problems. OD generally considered long term effort that is of at least one to three years in most cases. In addition, it mostly focuses on combined management where manager and workers of different level communicate and unite to solve the problem. OD understands the fact that all organization is different and same solution cant put in every co mpany. The other feature of OD is that it gives importance to team work and small group. The important features of OD programs is the change agent, that is group or individual which makes OD process much easier. Almost all change agent are consultant from outside who are experienced in managing OD programs but sometimes companies may utilize its inside managers. The benefits of consultant from outside are that they provide a different outlook and have a less biased view of the organizations problems and needs. The disadvantage of outside change agents is that its lack an in depth of understanding of main issues mainly one specific organization.

Schizophrenia: A Possible Etiology? Essay -- Mental Illness Health Ess

Schizophrenia: A Possible Etiology? As for me, you must know I shouldn’t precisely have chosen madness if there had been any choice. What consoles me is that I am beginning to consider madness as an illness like any other, and that I accept it as such. -in a letter to his brother Theo According to the National Institute of Mental Health, nearly 20% of the US population may suffer from a diagnosable mental illness in any given six month period (1991). Obviously the issue of mental health warrants close scrutiny, as such illness can translate into lost work days and lost dollars. From a health care perspective, many of those suffering can be relieved of their symptoms and return to normal life, so to speak. Schizophrenia, however represents one of the more disabling illnesses whose prognosis for the patient looks poor. Affecting nearly two million Americans, "schizophrenia" probably represents a grouping of many types of resembling illnesses (NIMH, 1991). Typically, the patient exhibits prodromal signs such as social isolation and withdrawal, role impairment, eccentric behavior, decreased affect, and disregard for personal hygiene. These then generally give way to intermittent psychotic episodes with intervening, sometimes long negative symptom periods. The so called positive symptoms of schizophrenia include disordered thinking and memory; the patient may display incoherent speech and rapid shifting to unrelated ideas. Delusions and false or bizarre beliefs, hallucinations, and perceptual difficulties also comprise the symptomology. Schizophrenic persons usually have an absence of feeling, a sense of remoteness and inappropriate reactions. Even more difficult to treat (Kandel) are the negative signs of poverty ... ...orks Cited: Kandel, Eric R. Disorders of Thought: Schizophrenia. pp. 854-868. Krieckhaus, E.

Subliminal Messages :: essays research papers

Subliminal Messages in Advertising: The Case For and Against Lisa Caswell Syracuse University Running Head: Subliminal Messages Subliminal messaging and subliminal perception are controversial topics in the field of psychology. Many studies have been conducted to determine if subliminal messaging does in fact work. Many people think that subliminal messages in the field of advertising are much more successful than subliminal messages for self-improvement, such as tapes sold to help the consumer lose weight, gain intelligence, or do something else to improve themselves simply by listening to a tape. Subliminal advertising can be defined as "embedding material in print, audio, or video messages so faintly that they are not consciously perceived." Rogers and Smith (1993) surveyed 400 households. When asked if they believed advertisers deliberately included subliminal messages, 61.5% responded 'yes'. A 72.2% 'yes' answer was obtained when asked if subliminal advertisements were effective. Based on these results, it can be concluded that consumers are aware of subliminal advertising, and believe it is effectively used by advertisers to influence their decisions. The term "sub-threshold effects," first popularized by Packard in 1957, preceded the popular notion of "subliminal advertising," whose originator is James Vicary. Subliminal advertising first came to the public's attention in 1957 when Jim Vicary conducted a subliminal advertising strategy of interspersing "drink Coca-Cola" and "eat popcorn" messages on a movie screen so quickly that they could not be seen consciously by the audience. His research initially reported increases in the sales of both Coca-Cola and popcorn as a result of the subliminal messages. Later, however, when he was challenged and could not replicate or even produce the results, Vicary admitted that the results of the initial study had been fabricated (Weir, 1984). Key (1989) has more recently claimed that hidden or embedded messages are widespread and effective. Key's theories have been widely discredited by scholars who have examined marketing applications scientifically (Moore, 1982). Although a few scholarly studies have reported certain limited effects of exposure to subliminal stimuli in laboratory settings (Greenwald, Klinger, and Liu, 1989), most academic researchers on the subject have reported findings which indicate no practical or predictable effect in an advertising setting (Dixon, 1971). The 1957 Vicary study has been largely disregarded in the scholarly community due to lack of scientific documentation of methodology and failure to replicate. However, scholarly findings and industry assertions may have had little or no effect on the average American, who has been exposed to popular articles and books promoting the notion that subliminal advertising is used and is effective. In addition, Americans have been exposed to advertisements claiming that self-help audio-tapes and videotapes containing subliminal materials can help the purchaser with weight loss, better relationships, an improved golf game, quitting smoking, and even birth control. Awareness of Subliminal Messaging by the Public
