Division Classification Term Paper

Bumper stickers are everywhere. In rush hour traffic they stare drivers in the face, and they amuse shoppers on the way back to their cars in the mall parking lot. Bumper stickers are drivers' way of shouting out their psychological attitudes, their favorite jokes, or their political or religious values. However, with all the bumper stickers out there it can be helpful to divide them into different categories. Most bumper stickers fall into one of three main categories: humor, attitude, and importance. To be classified as humorous, a bumper sticker must be about an important subject but at the same time be clever or satirical. For example, "Evolution is Intelligent," "Let Go of My Ears," "Grace Happens," "Yes, I'm Evil But it's a Part of My Charm," and "If you Want Fur, Stop Shaving" are all top humorous bumper stickers. Bumper stickers that boldly declare the driver's attitude toward any given subject can be placed in the Attitude category. The top five examples of attitude bumper stickers include "Yes, I'm evil but its part of my charm," "If you want to wear fur, stop shaving," "You're a Republican, and that's sad," "Caution-Driver is Legally Blonde," and "Come to the Dark Side -- We have cookies!" Importance is the third main category of bumper stickers. A bumper sticker can be classified as important if it relates to pertinent political, scientific, or health-related issues. Some of the top examples of important bumper stickers include: "Evolution Is Intelligent," "You're a Republican, and that's sad," "Grace Happens," "Let go of my ears," and "Caution-Driver is Legally Blonde." The top bumper stickers in these three categories include "Evolution is Intelligent," "Yes, I'm Evil but it's Part of My Charm," and "You're a Republican and that's Sad!" because they exemplify their particular category.

Each of the three bumper sticker classifications has criteria for membership. Humorous bumper stickers must fulfill the following criteria: they must be satirical or paradoxical, and they must also be about a topic that most people are familiar with. A bumper sticker that no one understands cannot be funny; a bumper sticker about a familiar topic that is not witty also cannot be classified as humorous. Second, bumper stickers that reveal the driver's attitude can also be funny but to be classified as attitude bumper stickers, they must also be about topics that overtly reveal the driver's attitude toward a certain subject such as politics or religion. Finally, important bumper stickers can also be funny and can reveal the driver's attitude. However, in order to be placed in the importance category, the bumper sticker must be about a highly relevant topic and not something that is trivial.

Humorous bumper stickers make most people laugh because not only are they witty but they also refer to familiar subjects. For example, the top humorous bumper sticker is "Evolution is Intelligent" because the sticker pokes fun of both evolution and intelligent design, fusing both concepts into one clever slogan. The slogan "Evolution is Intelligent" is… [read more]

Natural Selection Term Paper

Bibliography Sources: 1+


If there is simply no difference between the different genotypes or different genes in their impact on survival or reproduction, then what occurs are random changes of one vs. The other type in a population or a species until eventually one replaces the other (Natural pp). That is an evolutionary change that happens entirely by chance, by random fluctuations, and is called the process of genetic drift (Natural pp). Genetic drift is different from natural selection, which is a more consistent, predictable, dependable change in the proportion of one gene verse another or one genotype verses another, because there is some consistent superiority of one genotype verses another in a certain feature that affects its survival or some feature affecting its reproductive capabilities (Natural pp).

The two types of natural selection are ecological selection and sexual selection (Natural1 pp). Ecological selection arises from the portion of an organism's environment that is not related to direct sexual competition, such as access to food and the presence of predators, while sexual selection arises from the competition for mates between individuals of the same sex (Natural1 pp). This division exists because the effects of sexual selection can produce results that appear counterintuitive from the point-of-view of ecological selection alone (Natural1 pp). For example, peacock tails are both cumbersome and important for courtship displays (Natural1 pp). The genetic variation on which natural selection acts, is now known to arise from random mutations (Natural1 pp).

Marcellin Boule Who First Identified Term Paper

This issue is closely related to the extinction of Neanderthals. According to some scientists, the extinction of Neanderthals was a sudden phenomenon: they were quickly replaced by Homo sapiens in all areas they had populated. On the other hand, several other scientists believe the replacement of Neanderthals was a process that took several thousands of years. We are faced with two different evolutionary models to be described.

The multi-regional model asserts that there was a global evolution "modern H. sapiens because a sufficient level of interbreeding throughout the dispersed population was maintained over this long time period"

. This would obviously mean that replacement was gradual and it bases its theory on the fossil evidence showing that in several geographical areas, the hominid populations were stable over an interval of several thousands of years.

On the other hand, the replacement model suggests that "modern populations result from a recent global migration of mankind from a single locale that replaced any earlier hominids (such as Neandertals) whenever they came in contact"

. According to this theory, contact between more evolved hominids, such as the Homo sapiens, and less evolved ones, such as Neanderthals, would have resulted in a sudden replacement of the latter.

One of the mysteries of science and, especially, of evolutionary theories is related to the missing link in the evolutionary chain. There are scientist groups that believe the Neanderthals represent the missing link that we are all looking for. On the other hand, genetic research and significant anatomical differences come against the belief that the Neanderthals were just a regional variant of modern man.

Extinction Punctuated Equilibrium Evolutionists Term Paper

Term Paper  |  3 pages (1,127 words)
Bibliography Sources: 1+


And once again, the 19 different fossil species they traced revealed textbook cases of punctuated equilibrium... [another scientists named] Collins...recently took the same biologically based approach... Collins and his colleagues also found punctuated equilibrium in the evolution of these snails in California over the past 20 million years." (Kerr, 1995) So it is clear that punctuated equilibrium has good evidence backing it up both in the laboratory and in the field.

Theoretically speaking, punctuated equilibrium has a relatively strong case. First, it explains occasional "gaps" in the fossil record. (It is worth noting that the founders of the theory strongly object to the characterization of this theory as being drawn from "negative proof" of absences in the time line. They say it was actually founded on positive proofs from the fossil record. However, there are segments of the record where nothing seems to change, followed suddenly by massive signs of development. The theory is entirely distinct from saltationism, which is the theory that "New species may arise in single generation through a macromutation. Saltationism rejects Darwin's model of gradual change through generations." (Broyles, 1997) That theory is generally rejected by reputable scientists owing to its practical difficulties (with whom would the "Adam" or "Eve" of a new species mate?). Punctuated equilibrium still holds to the idea of generational change, but suggests that it happens relatively quickly (geologically speaking). periods of change may last from five thousand years to millions of years -- either is short in terms of the history of the earth. Between these times of radical change are periods of "stasis," times when no significant evolution occurs.

Despite the fact that punctuated equilibrium is frequently advertised, as it were, as being contrary to the ideas of Darwin, this is not actually the case; there is room in Darwin's original theory for punctuated equilibrium. In setting this case straight, Douglas Theobald (2003) explains that there are two forms of gradualism -- one which holds merely that changes occur gradually when they occur (even if they only occur at punctuated moments), and the other "phyletic gradualism" which holds that changes happen constantly. Punctuated equilibrium is consistent with the first position, but not with the second. Darwin himself, Theobald explains, was a gradualist, but he was not phyletic. The ideas of punctuated equilibrium are actually verbalized by Darwin, who wrote in Natural Selection: "I must here remark that I do not suppose that the process ever goes on so regularly as is represented in the diagram, though in itself made somewhat irregular, nor that it goes on continuously; it is far more probable that each form remains for long periods unaltered, and then again undergoes modification." (in: Theobald, 2003)

In conclusion, punctuated equilibrium appears to be increasingly proving itself as the most appropriate model for explaining evolution. Even if one is a creationist and does not believe in macro-level evolution, one must amidst that micro-evolution has been proved to exist in a way that can only be explained as punctuated equilibrium.… [read more]

Gould vs. Bethell Darwin's Untimely Term Paper

Term Paper  |  2 pages (998 words)
Bibliography Sources: 1+


Rather, just look at Darwin's first chapter that is devoted, as Gould notes, to 'artificial selection' of favored traits by animal breeders. For here an independent criterion surely operates. The pigeon fancier knows what he wants. The fittest are not defined by their survival. They are, rather, allowed to survive because they possess desired traits. Further: "Survival of the fittest" is not a tautology. "It is also not the only imaginable or reasonable reading of the evolutionary record. It is testable. It had rivals that failed under the weight of contrary evidence and changing attitudes about the nature of life. It has rivals that may succeed, at least in limiting its scope."

Further, adds Gould, the "principle of natural selection depends upon the validity of an analogy with artificial selection. We must be able, like the pigeon fancier, to identify the fittest beforehand, not only by their subsequent survival. But nature is not an animal breeder; no preordained purpose regulates the history of life. In nature, any traits possessed by survivors must be counted as 'more evolved'; in artificial selection, 'superior' traits are defined before breeding even begins."

In terms of the two corollaries, Gould argues that Bethell is looking at evolution only as an alteration in numbers, not as a change in quality. "Nature, however, is not limited by the calculations of theoretical geneticists. In nature, A's 'superiority' over B. will be expressed as differential survival, but it is not defined by it." Gould admits that his defense of Darwin is not radical or revolutionary. The main point is: Certain morphological, physiological, and behavioral traits should be superior a priori as designs for living in new environments. "These traits confer fitness by an engineer's criterion on a good design, not by the empirical fact of their survival and spread. It got colder before the woolly mammoth evolved its shaggy coat." As for the industrial capitalism of Victorian England, responds Gould, "according to Bethell, Darwin's concept of natural selection as a creative force can be no more than an illusion encouraged by the social and political climate of his times. In the throes of Victorian optimism in imperial Britain, change seemed to be inherently progressive; why not equate survival in nature with increasing fitness in the nontautological sense of improved design."

Concludes Gould:

I maintain, perhaps naively, that its (natural selection) current, unabated popularity must have something to do with its success in explaining the admittedly imperfect information we now possess about evolution. I rather suspect that we'll have Charles Darwin to kick around for some time.

(It is interesting to note that Gould's article was written in 1976 and a recent article in Discover Magazine describes how digital organisms that are "breeding" on computers at Michigan State University are proving Darwin's theory of evolution time and time again.)

Summary of Darwin's Untimely Burial Term Paper

¶ … Darwin's Untimely Burial" by Stephen J. Gould.

The topic concerns Darwin's theories of evolution and natural selection as explicated by Stephen J. Gould in his book, Ever Since Darwin. The specific focus is the fourth chapter, entitled "Darwin's Untimely Burial." In this chapter, Gould responds to arguments and corollaries presented by Tom Bethell, who holds that Darwin's theory of natural selection has disproved itself as a result of a logical error in argument. Gould uses his essay not as much to refute Bethell's claims of faulty logic, but rather to prove that, within Darwin's flawed argument, there remains a core of truth.

Bethell's first argument then entails that Darwin was essentially misled by his own lack of logical reasoning when constructing his theory of natural selection. Specifically, the author draws attention to the inherent tautology of the phrase "survival of the fittest," which basically defines fitness in terms of survival, and furthermore entails that those who survive, survive, which is an empty statement and not scientifically valid.

The transition to Bethell's second argument is achieved by a summary of Darwin's theory relating to pigeon breeding, and how this correlates with natural selection. Gould argues that Darwin's focus is on artificial selection for breeding purposes, according to which "fittest" acquires a different meaning to survival. In terms of breeding the term relates to predetermined, desirable traits, rather than a natural inclination towards strength of constitution.

Bethell's second argument is then that, because there is in nature no independent criterion relating to fitness, any argument for natural selection becomes tautological and scientifically invalid.

Bethell offers two corollaries for his argument. The first relates to the concept and nature of natural selection. The author questions natural selection as a creative force when fitness means only survival, as…… [read more]

Natural Selection First Term Paper

For example, a bug spray will not kill all ants or roaches. Furthermore, only those ants and roaches that are immune to the spray will survive and reproduce. Their offspring will also possess the resistant genes. The bug spray provided but a short-term solution to an insect problem. In the long run, more effective sprays must be developed. However, the same problem will happen with each subsequent spray development. In fact, the situation worsens because the harsher the chemicals become, the more hardy the ant populations will become. Before long, human beings might not be able to create chemicals that can challenge insect populations, or those chemicals might end up being more harmful or destructive than the insects themselves.

Of course, the human attempt to eradicate disease and eliminate threats to crops is noble. The attempt to control the environment by using these chemicals does provide some short-term benefits. For example, an antibiotic will kill off a virus or bacteria in the body that is causing a severe illness. Without the antibiotic, a bacteria or virus could cause permanent damage to internal organs. In many cases, taking antibiotics is a wise response to an illness. Similarly, a crop infestation might require a forceful use of pesticides in order to save an entire farm.

However, such products should be used judiciously to prevent the creation of super bugs or other resistant species. As the term suggests, natural selection is fully natural; it is an unavoidable, inevitable process. Those species that survive antibiotics, pesticides and herbicides are doing their "job" by reproducing. Unfortunately, many of these species prove harmful to human beings and the environment, especially as they become stronger through natural selection.… [read more]

Transitional Form Archaeopteryx Won't Fly Term Paper

Term Paper  |  2 pages (768 words)
Bibliography Sources: 1+


However, the fully formed nature of certain species coexisting with other supposedly more primitive forms, Gish argues, demonstrates the false nature of the transitional form species hypothesis. The notion of transitional forms reflects the Darwinian concept of "gradualism," or "the view that changes do not occur all at once, and that there are intermediate steps from an earlier stage to the next. ("How to be anti-Darwin, 1998)

Based on the information that I have posted on the external links section, what is Romer's Gap? What would Dr. Gish think of Romer's Gap (could it support or refute his beliefs)?

Originally, Romer's Gap was thought to support anti-Darwinian or creationist science. Romer's Gap was the gap or missing links between the seamless chain of evolution proposed, but not entirely supported, with fossil evidence, by Darwin. Today, it is noted, "there are folks today who still pretend that the fossil record reveals no links, no transitional fossils that demonstrate when and how evolution occurred. But before birds and whales could evolve (we have a fine series of fossils for them) tetra pods had to come into being. Their fossils are now coming to roost in museums too. Now, the "tetra pod's story," has essentially closed Romer's Gap, the website asserts, although Gish rests his argument not so much on a series of evolutionary gaps, but also of the co-existence of many species that were alleged to have evolved in a linear fashion, such as birds and reptiles.

What is the importance of the discovery of Acanthostega, and Ichthyostega?

Both of these discovered species of fossil close the 'gaps' in the tracing of the evolution of early fossil records, thus even if Gish's allegations about the bird-like creature he discusses may be true, the discovery of these tetra pods indicates that some of the other noteworthy gaps in the fossil chain are being closed through archeology.

Neanderthal Man the Debate Term Paper

For example, Neanderthal remains have been unearthed in burial sites all over Eurasia. The position of the remains demonstrates that the corpses were not simply thrown into the ground. Some graves have stone tools, animal bones and flowers buried in the ground along with the remains. In Uzbekistan, the grave of a young Neanderthal boy was encircled by mountain goat bones, horns and tools.

The fossil evidence shows that Neanderthals had burial rituals. This suggests an awareness of an after life. Each person had an identity that was distinct, whose passing was probably met with a sense of loss.

Adult skeletons with crippling injuries were also unearthed, indicating that Neanderthal ties were strong enough to compel them to care for injured or crippled members of their groups.

Finally, there is a plethora of evidence showing that Neanderthals and early modern humans interacted and behaved in very similar ways. Artifacts from France, for example, show that Neanderthals and early modern humans seem to have used the same caves and both hunted the same kinds of animals for food. Fossil remains of trout and other seafood indicate that both groups practiced fishing. The arrangement of fireplaces in the caves also suggest that Neanderthals smoked their catch for preservation.

Aside from harpoons and other hunting weapons, the caves also yielded engraved art objects. Since the caves were only used as shelter during hunting trips and not as living quarters, some anthropologists believe that carrying that Neanderthals carried small art objects with them even while performing everyday tasks. Carrying such iconography may be akin to a modern human carrying a rosary.

In conclusion, there is a wealth of fossil evidence to suggest that Neanderthal man is a subspecies of modern man, and should therefore be classified as homo sapien neandertalis. Allowing for the effects of a harsh, cold climate, Neanderthal physiology is remarkably similar to that of homo sapien sapiens. Neanderthal hunting tools and practices were similar to those of early modern humans. Neanderthals developed tools and had a capacity for language. They buried their dead, created artwork, had a concept of an afterlife and had a societal structure with strong social ties.

In both their anatomy and behavior, Neanderthal man exhibited many characteristics on which modern man bases its definitions of what it means to be human. When compared according to anatomy, behavior and cultural practices, Neanderthals bear more than a passing affinity to modern man. Hence, they belong in the human family lineage, under homo sapien neandertalis.

Substance Abuse and Alcohol Dependency Discussion and Results Chapter

Discussion and Results Chapter  |  2 pages (633 words)
Bibliography Sources: 1+


Alcohol and other drugs are substances that typically go together when it comes to dependency. The latest research indicates that alcoholics are also more likely to abuse drugs than people who have no dependency upon alcohol (Falk 100). This is because both types of substances have similar effects on the mind and body of the user (not all drugs act the same of course, but there are those that can act as depressants, like alcohol, while there are others that can act as uppers). Some combination of the two can also be used, alcohol as a depressant and drugs as an upper, to allow the user to experience a range of feelings. The idea behind this two-way substance abuse is that an individual who is willing to abuse one substance will have less reluctance to abuse another than an individual who is not willing to compromise and abuse any.

When individuals have a co-dependency on both drugs and alcohol, their addiction is likely to be far worse than an individual with a dependency on just one substance (Falk 101). What causes addiction to either substance is still debated among researchers, but there are various theories about why some people develop dependencies and others do not. Genetic theory is one approach to this explanation, while social learning theory is another. Biological, psychological, social, genetic, behavioral, and socio-economic theories all serve to help explain the reasons that drugs and alcohol serve as powerful factors in some people's lives and not in others.

Diagnosing an individual with alcohol or drug dependency is not as easy as one might initially imagine. Some individuals do not like to admit that they have a dependency and thus try to hide it or explain the signs away as having a root cause in some other affliction. Persons who hide their addictions are far less likely to receive a proper diagnosis than those who…… [read more]

Men Who Have Successfully Come Off of Methadone Maintenance in Connecticut

Available studies, reports, articles and documents on the issue will be analyzed. Policies that have bearing on the treatment program will also be analyzed (Nguyen, Nguyen, Pham, Vu & Mulvey, 2012). A special questionnaire will be developed to gather information from the participants. The questionnaire will include: items on former drug use details (needle sharing, preference for injections, daily dose and history of drug abuse), items on methadone treatment status (e.g. time of receiving treatment and dose), demographics and sexual practices (e.g. frequency of sex per week, number of sexual partners, and condom use within 12 weeks to the commencement of treatment) (Zhang, Zhang, Shi, McGoogan, Zhang, Zhao & ... Wu, 2014).

The Variables under Study:

Structured Clinical Interview for DSM-IV

Substance abuse disorders listed under Structured Clinical Interview for DSM-IV [38] will be used to record the substance abuse history of the individual. The aforementioned interview helps one to report the use of different substances of abuse, such as cannabis, amphetamines, cocaine and other substances. Though structured, the interview can also be tailored to enable more precise differentiation of substance abuse by the interviewee (Nguyen et al., 2012).

ii. Fatherhood and Substance Abuse Structured Research Interview

This interview will be used to gather data on historical and current aspects of responsible fathering. This structured interview has in the past been used for the current kind of study in investigating the nature of substance use among men. The interview will be used to gather data on: financial and educational background of the participants; the demographic of the participant's children; and aspects of reproduction (Zhang et al., 2014).

Independent and Dependent Variables Defined (Quantitative) and Concepts (Quantitative)

Eight risk factors of sex dysfunction will be used for the study among the men who came off the methadone. They include: familial status, other substances abused; psychiatric illness; health status; methadone dose; duration of intervention; hormone assays and age (Gomes & Nobre, 2012).

Research Procedures

The cross-sectional study will be done at a Connecticut hospital for 3 months. All participants will be recruited from the hospital's MMT clinic. At any given time the hospital handles more than 500 heroine-dependent persons, the majority of whom are usually men (Zhang et al., 2014; Nguyen et al., 2012). Questionnaires will be administered to gather data from the participants. The questionnaires will include aforementioned items such as: the substance abuse history of the individual (needle sharing, preference for injections, daily dose and history of drug abuse), items on methadone treatment status (e.g. time of receiving treatment and dose), demographics and sexual practices (e.g. frequency of sex per week, number of sexual partners, and condom use within 12 weeks to the commencement of treatment) (Nik Jaafar, Mislan, Abdul Aziz, Baharudin, Ibrahim & Midin, 2013).

Blog about GWU's Alcohol Policy

Did you know about the policy when you applied/entered the University (Fall 2012)? Do you think it is adequately publicized in the admission and/or orientation materials?

I was only vaguely aware of the GWU alcohol policy when I applied because alcohol and drug policy were of minimal concern to me regarding my priorities in selecting a school. The school's academic reputation, its location, whether it had my major, and success of recent graduates were all of greater concern. While on one hand, I suppose the policies could be better publicized, on the other hand I think few students choose their school based upon written university alcohol policies. Only when on campus does a student really understand the extent to which alcohol policies are or are not vigorously enforced.

Are there any special groups, clubs, or organizations that seem to be targeted for education about, or enforcement of, the alcohol policy?

Ironically, I think the organizations that are most notorious for allowing heavy drinking in academic settings such as fraternities, sororities, and athletic teams, are often the best poised to educate students and to help create events which are fun and alcohol-free.

Is there any drinking behavior that is strictly prohibited at all functions even if the participants are over 21? What is it?

Fundraisers are strictly prohibited from serving alcohol. There are also a number of other prohibited occurrences; such as serving alcohol outside of specified hours; serving alcohol for free; and serving alcohol by non-GWU school personnel. Security personnel must be present and it is strictly prohibited to have methods of distributing alcohol like punch bowls, which could lead to excessive consumption.

Do you think the policy is adequately enforced? Is the administration, faculty, staff, PD, encouraged to support the policy?

Compared with schools where my friends attend, yes, I do think the policy is adequately enforced. There is more of a commitment to supporting a drug and alcohol-free environment versus other schools where abuse is often tacitly tolerated.

Are students involved in policy formation?

Students must submit requests to serve alcohol at specific functions but they are not necessarily in charge of setting the actual policies and procedures.

If you were in charge of rewriting the policy, what changes would you make?

There are no major changes I would make; the university policies are designed to ensure that there is a zero-tolerance policy for underage drinking and it seems reasonable that underage students would not have a major say in how such a policy was articulated. However, I do think there should be some specifications about what will be done if students are found in violation of the policy. Rather than disciplinary action, I would be…… [read more]

Neurobiology and Abuse Potential of Rohypnol Research Paper

Research Paper  |  2 pages (620 words)
Bibliography Sources: 3


Rohypnol (Flunitrazepam) is a drug in the class of the benzodiazepines (Stahl, 2013). It is an intermediate-acting benzodiazepine that is similar to Valium (diazepam). Rohypnol was developed as an aid for sleeping that would not produce significant daytime drowsiness due to its relatively short half-life (Stahl, 2013). It has also found use in psychotherapy to relax patients and to get them to open up, as a pre-medication in surgical procedures to relax people, and to induce anesthesia (Stahl, 2013). The drug is manufactured in Europe and Latin American; however it is not approved for use the United States and Canada.

Like other benzodiazepines the effects of Rohypnol include sedation, reduced anxiety, muscle relaxation, and it helps to prevent convulsions (Stahl, 2013). The sedative effects of Rohypnol effects are approximately 7 to 10 times stronger than those of Valium. Rohypnol's clinical effects begin around 15 to 20 minutes after administration and continue for about four to six hours; however, residual effects have been reported 12 hours or more following administration (Stahl, 2013).

Rohypnol (and all benzodiazepines) act as positive allosteric modulators on the gamma amino butyric acid (GABA)-A receptor (there are three types of GABA receptors, these drugs act primarily on the GABA -- A receptors; Stahl, 2013; Tan, Rudolph, & Luscher, 2011). GABA is the most common inhibitory neurotransmitter in the central nervous system and is prevalent throughout the cerebral cortex and limbic system (Stahl, 2013). Rohypnol is primarily a GABA agonist (Tan et al., 2011). This means that it mediates GABA neurotransmission in the brain and spinal cord by binding to the GABA receptor, and leading to the opening of the chloride channels of neurons which results in the influx of chloride and the hyperpolarization of the cell resulting in release of GABA (Stahl, 2013; Tan et al., 2011). This action decreases the excitability of the neurons producing sedation…… [read more]

Is There a Heroin Epidemic Research Paper

Epidemic Heroin Use

If recent news reports are to be believed, heroin is coming back with a vengeance in the United States. While crack and methamphetamine have gotten a lot of the attention in recent years and decades, heroin has always been there. Whether it be in pure street form or in the form of narcotic painkiller pills that are currently rampantly abused, opiates in all the forms are leading to a lot of people becoming addicted, overdosing or even dying. Even when death is not realized for an addict, their lives and often the lives around them are left in shambles. Despite the obviousness and gravity of the overall problem, the solutions to the problem can be elusive because the people stricken by opiate abuse have to want help for any rehabilitation to actually stick.


One website and overall source out there that focuses on the heroin epidemic is known as Monitoring the Future. Their self-described mission is to monitor the progress and travails of American youth. To aid in this endeavor, the monitor about 50,000 students in 8th, 10th and 12th grades. The 12th graders have been surveyed for two generations, dating back to 1975. The other two grade levels became part of the survey process in 1991, or about 24 years ago. Overall drug use besides marijuana (which would obviously include heroin) is actually not all that bad over the recent years. There was sky-high spike of nearly forty percent in 1980 but there was a fairly steep fall after that until 1992. There was a rise again from about eighteen percent to about 21 to 200% but there has been a gentle fall since then. This is among the 12th grade group. The percentages of the 8th and 10th graders is lower and has also been tailing off cine it started to be assessed in 1990 (10th graders) and 2002 (8th graders) (MTF, 2015).

When looking at opiates other than heroin, the overall trends are also good, at least based on what is known. Much the same thing can be said about heroin in particular. In looking at the 2014 annual report as it pertains specifically to heroin, heroin use with or without a needle has been flat since roughly 2011. Even so, there was a 2010 spike in 12th graders but it was to a mere 0.7%. In short, overall use of heroin among school-age students is rather low. The "disapproval" rates are extremely high when it comes to heroin. In 1980, about a fifth of students in 12 grade said that they could get heroin "fairly easy" if they wanted to. This spiked to 35% and stayed there roughly from 1992 to 1998. There has since been a gradual but sustained fall in his number. Pill-based opiates have been used much more prevalently as of late but heroin use is mostly flat or falling (MTF, 2015).

Films and Music -- Impacts on Social Norms

The question of how much of an influence music and film has on social norms -- or on society as a whole -- has been explored in the literature for many years. And there is today a great deal of scholarly literature based on the question of the degree of influence (movies, music) that the media has on society. In this paper I will focus more on the influence of music and film on young people, and I have long believed music in particular has had a huge impact on young people. Reviewing and critiquing the scholarly literature for this paper I have found strong support for my thesis, which is that: a) rap music, or hip hop, and especially what they call "gangsta rap," has had an enormous influence on young people, in particular young people of all ethnicities, but seemingly African-Americans in particular; b) and the violence portrayed in film and on TV has influenced young people in a negative way.

Rap / Hip Hop and Aggressive Behaviors

In the Journal of Studies on Alcohol the authors assert precisely what I have been suspecting about young men (and women) who are frequent listeners to hard core rap music (hip hop actually comes under this category as well). Chen and colleagues assert that young people listening to hip hop and rap " ... are more likely to engage in substance abuse and aggression" than other young people who listen to pop music or country and western (Chen, et al., 2006). The authors certainly express ideas and survey results that exactly match my suspicions and my viewpoints after I have listened to some of the more provocative lyrics on these "songs."

Chen references a study conducted by the National Institute of Alcohol Abuse and Alcoholism reported that when young people are exposed (frequently) to music that has violent and substance use themes those young people often become involved with substance abuse and alcohol abuse (p. 3). The study (surveying 1,056 students ages 15 to 25 years) showed that the frequency of "any alcohol use was positively and significantly associated with frequent listening to heavy metal ... punk, rap, R&B, reggae, rock and techno"(Chen, p. 3). But when compared with other music genres, rap was "consistently and positively associated with ... alcohol ... marijuana, club drugs, and aggressive behavior" (Chen, p. 3). The more I delve into the scholarly literature, the more my own suspicions and beliefs about the relationship between hard core music and antisocial behaviors are verified.

Rap Music and Misogyny

Beyond the violent lyrics found in gangster rap, I have also been discouraged and even outraged at the popularity of some rap lyrics which celebrate misogyny -- and how these lyrics advocate violence against women. Just last week I attended a high school football game in an urban environment, and before the game, while the teams were warming up on the field, a loud hip hop tune was playing and… [read more]

Two Part Answer on Drugs Essay

¶ … Parents are no exception. In the modern world, many have experimented with drugs with parents being no exception. Especially now that marijuana faces potential legalization across the United States, what was once deemed wrong and illegal for all is now considered acceptable for many. Parents therefore have a choice as to whether or not to come clean with their drug usage to their children and see if it helps or hurts their child's chances of taking drugs or not.

Parents are human first and although it may seem counterproductive in the beginning to admit having taken drugs, (if they took it) it may actually help their children in long run. This is especially true if the parent who took the drug had a negative experience because of taking the drug. This could be being arrested, losing their job, going into addiction, or other negative experiences. At times, the mere idea of seeing the negative outcome of taking drugs could transform a child's curiosity into disdain and disgust for drugs.

Even in the case of marijuana where the parent may have had positive experiences, it is still important to let the child know if the parents has taken marijuana. This is because the parent can then prepare the child for possible reactions the child may face from taking marijuana. Marijuana is legal now in several states even on the recreational level. Therefore, if your child wishes to partake in that drug, that child can do so much like alcohol.

Preparing the child by letting the child become aware of potential side effects or freak-outs, will help the parent avoid any hiccups in the child's awareness of some drugs like marijuana. My mom never took drugs but told me of how dangerous it was and how it affected her relationship negatively with her husband at the time who did take marijuana. This made me painfully scared of participating in taking the drug. However, eventually I got curious and tried it. Since I had no idea of what to expect, I had a freak-out. If…… [read more]

Neanderthal and Modern Human Differences and Similarities

According to Trinkaus, Neanderthals do not deserve their reputation as evolutionary lugs. The name Neanderthal has become a byword for stupidity and boorishness. However, do the Neanderthals deserve this characterization? Examinations of the Neanderthal anatomy do not indicate that Neanderthal anatomy is not any way inferior to modern humans. Neanderthals have been added officially to the human species Homo sapiens, though they are mostly placed in their own subspecies, Homo sapiens neanderthalensis.

While the Neanderthals are not inferior, there are quite some differences between them and modern humans. Why the Neanderthals evolved 100,000 years ago in Europe and the Near East and why they were replaced by modern man is unknown. Trinkaus postulates that there is some behavioral significance to the anatomical differences between the Neanderthals and other human groups is to find out what the natural selection had to do with this process. The bottom line question is what happened to the Neanderthals themselves.

Everything about the Neanderthals with reference to strength including the muscles ligaments and bones indicates strength and the ability to generate and deal with stress. The bones themselves are modified to have more bone and less marrow to deal with these heavier stresses. Even the hands show identifiable crests to indicate where the muscle attaches to the hands. On modern human hand bones there are none, indicating that the attaching muscles were not as strong or robust. All of this is valid also for the lower limbs (Trinkaus 140-141).

The reasons for the extinction of the Neanderthals are one of three possibilities including environmental, interbreeding with modern humans and violent conflict. Given the possibility of intergroup conflict, any evidence of trauma is dealt with problematically by archaeologists and anthropologists. Certainly, it is also possible that all of the above possibly true in some way and may have been happening globally at the same time.…… [read more]

Hunting the First Hominid Reaction Paper

Reaction Paper  |  2 pages (707 words)
Bibliography Sources: 1


¶ … Shipman is Wrong

The author has some problems with Shipman's analysis. Certainly, she is right in the fact that humans are very narcissistic and want to know where they come from. It lets us know what makes us tick and helps us psychologically to sort out who we are.

She is certainly right when she says that the more primitive sciences such as paleontology that more dependent upon the unaided human eye and human brain say more about this than more high tech approaches, although tech is sometime helpful and necessary, especially with regard to dating remains and to reading the chemical evidence of "molecular clocks." Also, with certainty this "missing link" of an ancestor is certainly from Africa because our closest living relatives (chimpanzees and gorillas) and therefore all early hominids will also be African. Also, the consensus (upon which this author agrees) is that the first hominid was not a human and did not possess all of the characteristics that we consider human.

So what would the first hominid look like? This is of course where the consensus breaks down completely. Much of this analysis is really the anthropological equivalent of Monday morning quarterbacking after the Sunday Super Bowl game. As Shipman notes, the first species in any new lineage is usually readily apparent only ex post facto.

Some of the differences between apes and humans however are non-issues. Many of the scholars agrees on a number of issues. Research is not clear when the line became bipedal. Certainly, the first in the line was an ape, but not one of the living great apes such as the gorilla or the chimpanzee due to the 5 million years needed to evolve in isolation before arriving at their modern forms. In addition, once the line became bipedal, they became hominids with small brains and body size akin to that of ape. Also, Shipman contends that sexual dimorphism started to be exhibited in ways not related to reproduction. Enamel thickness in teeth is also an issue. Apes have thin enamel in the chimp and gorilla lineages (not the orangutan, but they…… [read more]

Neanderthals Grew Fast, but Sexual Maturity Research Proposal

Research Proposal  |  2 pages (500 words)
Style: APA  |  Bibliography Sources: 1


¶ … Neanderthals Grew Fast, but Sexual Maturity Came

Late; National Geographic News, September 8, 2008. By Kate Ravilious. Traditional beliefs about Neanderthals held that our closest known relative died out because they were inadequately equipped to survive and intellectually inferior to modern humans. In many ways, those beliefs are central to the presumed qualitative superiority of human beings to all other forms of animal life, both in the distant past and on earth today. However, recent findings suggest that Neanderthals were much closer to human intellect as evidenced by their cooperative hunting and tool-making abilities.

Even the current understanding of the factors responsible for their ultimate demise closely parallels issues in human physiology, in particular, medical complications that still affect childbirth among modern humans.

Unlike so-called "lower" animals, Neanderthals apparently reached sexual maturity relatively late in their chronological development, even later than modern human beings. Like modern humans, brain growth among Neanderthal infants proceeded rapidly after birth, necessitated by the physical difficulties of birthing in conjunction with a more fully-formed brain and correspondingly larger cranium. The researchers determined that the anatomical differences in the facial structure of Neanderthals necessitated greater brain growth rates in the first few years after birth in order to compensate for the additional birthing difficulties posed by differences in their anatomical facial structure in relation to the geometry of the birth canal to ensure live births.

One of the main factors that contributes to the fact that human infants are born intellectually undeveloped is that…… [read more]

Concept of Economic Darwinism Theory Term Paper

¶ … Economic Darwinism Theory

Economic Darwinism

Definition of the concept: Many economic terms flood our everyday academic life. Economic Darwinism is one of them and relates to the way individuals (and managers in our case) behave on the market place. Why is this important? Because the behavior of managers influence the activity of the company they ran, so from a particular perspective we can say that it influences the competition, the rivalry among competitors, and also to a certain extent the goods made available to end-consumers. Economic Darwinism implies two different aspects: selection - in case of behaviors leading to different results, people tend to replace the behavior with the lowest performances with an arbitrary behavior, and mutation - when a particular behavior has a positive aspect, then the individual has little incentives to pass to an arbitrary behavior.

Example of the concept

When considering different investments, for example, managers have different business alternatives which must be analyzed in order to convey the best alternative that will meet the objectives of the investment project. The analysis is based on different criterions, each criterion receiving a…… [read more]

Hairy Ape by David Auburn Term Paper

Hairy Ape by Eugene O'Neill

Analyze how Yank's anguish/anxiety, in "The Hairy Ape" by Eugene O'Neill, is philosophical and universal.

References specific to working and upper class life during America's Guided Age, like expensive transit upon ocean liners, illegally unionizing socialist workers like the Wobblies (I.W.W), and the extreme disparities between the rich and the poor belie the fact that the central protagonist's Yank's anxiety about his lack of social mobility is not limited to his day and age. The central, anguished image of the play is that of a man who is intensely powerful and physical and who is ultimately overcome by his primate ancestor. Ironically, Yank has admired this universal ancestor in the zoo as a fellow captive out of his true state of nature, as Yank was in prison.

Discuss how the play emphasizes Darwinism and Reverse Darwinism.

Yank begins the play as a fireman and coal worker on a Transatlantic Ocean Liner. He physically dominates the men around him, who obey his requests for drink without question. However, Yank is physically rather than socially and intellectually superior in manner -- he dominates them through implied violence, not because they admire him. This is Darwinian survival of the fittest, but only the fittest physically, not mentally or spiritually -- thus is also a kind of a reverse Darwinism when this fact is enacted upon the stage.

In the first scene, even…… [read more]

Homo Erectus Term Paper

Term Paper  |  3 pages (995 words)
Bibliography Sources: 1+


Long Foreground: Species Timeline, p.4) Most anthropologists using conventional dating techniques believe that Homo erectus originated in Africa and soon after migrated to these other continents because, geographically, the land masses of the earth were connected in areas that they are not connected today. "In 1984, a nearly complete fossil skeleton of an adolescent Homo erectus boy was found near Lake Turkana in Kenya. The fossil is about 1,600,000 years old. The skeleton indicated that he had died at about 11 or 12 years of age. The fossil is the most complete skeleton of an early human ancestor ever found." (Mann, 2005) "This boy stood more than 5 feet tall when he died, and would have exceeded 6 feet -- had he lived to maturity. His cranial capacity was 880 cc and his body stature (tall, thin, long arms and legs) are typical of humans adapted to open, tropical environments." ("Homo Erectus," 2005)

But although the fossil and environmental evidence is convincing regarding the "Multi-regional" hypothesis, it is not conclusive. Some anthropologists think that the earliest Homo erectus fossils from Africa should be called by another name, Homo ergaster. These anthropologists point out that these earlier African fossils have thinner skull bones than those of later Homo erectus fossils found in Asia. They believe that Homo ergaster migrated out of Africa to Asia and that Homo erectus developed from this earlier species. But there is a great statistical unlikelihood of such an evolutionary development occurring in parallel over wide areas. (Long Foreground: Species Timeline, p.1)

Still, merely because it is statistically unlikely does not mean the theory called the "Out of Africa" model is impossible. Scholars who advocate this theory believe "that that it was not a gradual worldwide change that led to the evolutionary transformation of populations of Homo erectus, but a speciation event in a single population in Africa, which then spread throughout the Old World and replaced established populations. Allan Wilson advanced the theory in 1987 and said that genetic evidence suggested that all modern humans evolved from a single female that lived in Africa approximately 200,000 years ago. This is also known as the "Mitochondrial Eve Hypothesis," as biological or genetic data supports this thesis more than fossil and environmental evidence. ("Homo Erectus," 2005)

Anthropologists even disagree on the fate of Homo erectus. Some think that as Homo erectus was an ancestor of modern human beings, it gradually faded into genealogical history. Others think the species became rapidly extinct. (Mann, 2005) And until another great fossil find occurs, or another significant advance in the dating of fossil and archeological evidence, the debate is likely to continue within the scientific community.

Probability -- Subjective, Relative Frequency Term Paper

Bibliography Sources: 1+


("Fitness," Internet Encyclopedia of Philosophy, 2003) Darwin's theory of natural selection provided an explanation of all three of these features of the biological realm without adverting to some mysterious designing entity, thus making it valid on a level of subjective probability, as well as was relatively probable, given the fossil records and environmental variations of the same observed species.

Karl Popper's Propensity Interpretation of the 20th century aimed to solve the problem how to assign probability to the outcome of an individual experiment with an indeterminate outcome, such as experiment designed to prove the existence of ESP delineated above. "While the Classical and the Frequency Interpretations try to reduce the notion of probability to other, already known concepts, the Propensity Interpretation identifies probability with a new quantity, called 'propensity', expressing the measure of the 'probabilistic causal tendency' of the system to behave in a certain way." (Propensity, 2001)

Their beaks had evolved over time to be best suited to their function.

For example, in areas with many grubs, the finches who survived in greatest number were those with thin extended beaks. These birds could more easily poke their beaks into holes in the ground and extract the grubs. Finches with claw like beaks were less sucessful at this. But, they could more easily eat buds and fruit and could grind down their food, "giving them a selective advantage" in other natural circumstances where buds were the main food source for finches.
