Psychology of Sexuality

Since the dawn of mankind, sexuality has played an enormous role in the complex social behaviors exhibited by our incredibly unique species. Sex contributes not only to reproduction, but also to relationships between people, cultural norms, and mental health. There are many important factors that contribute to sexuality; one of the most important factors is sex differentiation.We can take this even further and look at reproductive anatomy and the differences between the male and female reproductive systems. Thus, this paper discusses the history of sex, male and female reproductive anatomy and physiology, and finally human sex differentiation. The history of sex is interesting especially because of the controversy over the length of the time span from whence it was recorded. John Gagnon argues that it was really the turn of the 19th century when sex research emerged.While many (if not all) of Sigmund Freud’s theories have been disproved by this point in time, he did hit on man y major ideas about sexuality and was one of the first people to really think and talk publicly about it, as well as Havelock Ellis. Freudian theories were extremely influential in shaping future theories and research, even throughout the late 20th century. Another important player was Alfred Kinsey, who built upon previous researchers and made note of the social changes around the 1950s, in turn affecting policy, general attitudes towards sex, and future research.Winston Ehrmann agreed that the history of sexuality is quite a short field in his work â€Å"Some Knowns and Unknowns in Research into Human Sex Behavior,† arguing that and while there has been documentation about sexual behavior throughout history, a more scientific approach to sex only really begun since the late 19th Century. However, I would contest that it’s a distinction based more on a social construct of what constitutes a scientific study in Western society.For example, ancient Indian literature of the Kama Sutra can be said to have treated sex as a science, giving practical advice about sex as well as showing the various positions in detailed paintings. There is also detailed historical evidence of homosexual behavior among men in Ancient Greece. While Ehrmann may not have considered these sources scientific, I would argue that for their respective time periods, they were as scientific as could be expected. In fact, we can’t really judge whether something was â€Å"scientific† since what we consider scientific in a modern Western sense may be completely different from their nderstanding of scientific back in the days of Ancient India or Greece. For a perspective of the history of sexuality from around the globe, we go back further in time and look at eighteenth century England, as well as ancient African Bushmen. Hera Cook writes an article â€Å"Sexuality and Contraception in Modern England: Doing the History of Reproductive Sexuality† in which she argue s that historians have ignored reproduction as a factor relevant to and influencing sexual mores and change. Pregnancy, and the resulting child, is not only a physical demand and economic cost, but a health risk.Effective contraception was not available and alternative sexual practices were not acceptable substitutes for vaginal intercourse. While I agree with most of her arguments, I would contest her claim that many historians dismiss reproduction as a factor of changes in sexuality. In fact, the next article â€Å"The Century of Sex: Gender, Bodies, and Sexuality in the Long Eighteenth Century† by Karen Harvey discusses sexuality in England during the 1700s and does consider the effects of reproduction.Harvey argues that prior to the Eighteenth century, men and women were â€Å"placed on a vertical, hierarchical axis, in which their bodies were seen as two comparable variants of one kind† in a sort of â€Å"one-sex model† based on the four humors of different qualities – cold and moist, which dominated women, and hot and dry, which dominated men (Harvey, 2002, p. 901). Furthermore, they thought of sex organs as simply the reverse of one another; a vagina was like an inside-out penis, the labia corresponded to the foreskin, etc.However, towards the eighteenth century, there was a shift in the understanding of bodies towards a two-sex model. Anatomical differences were stressed and their bodies were regarded as qualitatively distinct. While previously the female orgasm was previously thought to have importance for conception, it was ultimately deemed unnecessary. Women were reimagined from â€Å"lascivious and lustful creatures† to having no sexual needs whatsoever (Harvey, 2002, p. 903). Homosexuality was highly frowned upon and considered perverse and sodomy.On the other hand, a certain ancient African Bushmen tribe had a much more egalitarian view on sexual behavior and gender differences. Marc Epprecht discusses the hist ory of the zvidoma, the orginal inhabitants of Zimbabwe in his book â€Å"Hungochani: The History of a Dissident Sexuality in Southern Africa. † Epprecht notes that these ancient Bushmen were hunters and gatherers using Stone Age weapons and tools comprising a classless communitarian society with no concept of individual ownership or property. Decisions were made by group consensus, and this included females; uncommon for that time.While there was a clear gender division of labour, the zvidoma were closer to egalitarian than any other culture in ancient African history. Not only did they traditionally marry monogamously, but women could divorce relatively easily and retain rights to sexual autonomy. Depictions of women’s genitals in cave paintings suggest â€Å"a source of vital, mystical energy at least on par with men’s† (Epprecht, 2004, p. 25). Because of their limited geographical area as well as their method of hunting and gathering, they had to be c areful to avoid overpopulation.During times of hunger, they practiced sexual restraint and possibly infanticide. Furthermore, there is a rock painting at least 2000 years old depicting three males engaged in anal intercourse as well as two male couples, one embracing face to face and the other also engaging in anal sex with an overly large emphasized erect penis. There are not many paintings depicting sexual practice, but the relative scarcity of ones depicting homosexual practices as well as paintings with heterosexual sex suggest they were equally commonplace.While the history of sexuality gives us a good basis on which to study the psychology of sexuality, some would argue this basis is biased toward differentiation. Merry Wiesner-Hanks argues that women’s and gender history over the last few decades has spent too much time on divergence, making more and more complex categories of difference over sexual orientation, marital status, able-bodiedness, gender relations, etc. H owever, I argue that it is necessary to study these differences in order to properly ascertain similarities and relations between the sexes.First and foremost we will discuss the biological and anatomical differences between the genders, then later human sex differentiation in a broader, more psychological and social construct. Historically, fixing sexual types became popular in the eighteenth century, according to Londa Schiebinger in â€Å"The anatomy of difference: race and sex in eighteenth-century science. † It was a great age of classification. Just as natural historians flooded Europe with new strange flora and fauna from the New World, new cultures were being discovered in America.Thus they sought new and simple principles that would hold universally, and tried to define the genders. This set the stage for genders to be divided in an evolutionary context. Judith Lipton and David Barash posit in â€Å"Gender Gap: The Biology of Male-Female Differences,† that bio logical differences between men and women have a strong and direct correlation with evolution. They argue that we can look to other species to learn more about ourselves. Just as scientists look at E. Coli to study the replication of DNA, we can look at other living creatures and see our sex differences mirrored there within.However, Katarina Hamberg challenges that argument. She thinks that using sex differences seen in biological experiments on animals to explain gender differences in humans is ridiculous. I agree with her that this is completely unscientific. Gender differences as well as gender itself varies greatly between species. In fact, in many species the female is bigger than the male. Furthermore, she is often stronger and will sometimes consume the male after sex in order to give strength to her developing babies, as with many arachnids and some insects.Therefore we can hardly compare studies on animals to human sex differences, though we can certainly look at the diffe rences and ponder the implications. Hamberg also argues that throughout history, biological arguments have been used in order to legitimize a social gender order characterized by male supremacy. This is more problematic, for while men are physically stronger and bigger than women, they are certainly not more intelligent nor are they naturally more disposed to leadership. In fact, some studies have shown that women possess more of the skills necessary to lead well and do better academically.The male and female orgasms are an important biological distinction in a reproductive, evolutionary, and social context. In â€Å"Why Women Have Orgasms: An Evolutionary Analysis† by David Puts, Khytam Dawood and Lisa Welling, the evolutionary adaptation of the female orgasm and its purpose is discussed. There are two possible likely hypotheses; firstly the mate-choice hypothesis which holds that female orgasm has â€Å"evolved to function in mate selection† and secondly the byproduc t hypothesis which asserts that the female orgasm in fact has no evolutionary purpose and rather exists because women and men share early ontogeny with men.They found the first hypothesis to be more likely, which seems the case to me as well. Another article â€Å"Women Who Prefer Longer Penises Are More Likely to Have Vaginal Orgasms (but Not Clitoral Orgasms)† discussed vaginal versus clitoral orgasms and the evolutionary implications. Their method was to have over three hundred women report in an online survey; however, people may not always be truthful in surveys, especially those discussing sensitive matters like sex, therein lies a possible problem with their study.They were able to find a positive association between likelihood of orgasm with a longer penis and vaginal orgasm frequency. Finally â€Å"Human Sperm Competition† discussed the concept of sperm competition, the competitive process between spermatozoa of two or more different males to fertilize an egg of a lone female. They were looking into the claim that sperm competition has an effect on mate selection in humans. This study also involved the use of a survey with approximately 400 men and women. The results of the survey showed that sperm competition was most likely not a huge factor in mate selection.On the other hand, perhaps this is something that evolved recently since nowadays there are many options for couples who have trouble conceiving such as adoption, artificial insemination, use of surrogates, etc. thus the ability to conceive a child naturally is not as important in mate selection now as it may have been earlier in human evolution. Contributing to sex differences such as these is different concentrations of steroids and hormones delivered to the fetus, which can have lasting effects throughout a person’s life.After looking at sex differentiation in a biological context, we must consider how and why females and males differ in behavior, psychology, genetics, a nd pathology? Certainly, it has long been posited that there is a divide in spatial abilities. Patricia Gilmartin and Jeffrey Patton assess this in â€Å"Comparing the Sexes on Spatial Abilities: Map-Use Skills. † They suggest that males are more proficient than females in many types of spatial tasks. Furthermore, they found these differences were greater in childhood, especially in relation to maps, geography, and navigation based tasks.Among college students, these differences in map-use and navigation were negligible. I would have liked to see them look into the concept of men preferring not to ask for directions or use a GPS to navigate – a long standing gender joke, but possibly true. Certainly this has proved true in my experience driving with my male family members and friends. However, I would posit that it varies culturally, for example in respect to Japanese people who don’t have this social construct of men not asking for directions. Another dimension on which genders vary is leadership.Cheryl de la Rey argues in â€Å"Gender, Women and Leadership† that the question is not only whether genders vary in leadership ability and skills, but whether they vary in leadership styles as well. These differences in leadership style, she posits, are not reducible to biological differences, nor can they be adequately explained by socialization and sex roles. Rather, it’s about how gendered behaviors become more dominant within organizational contexts that are masculinized. This leads to the hindrance of women’s access to leadership positions via discrimination and stereotyping.Part of the problem is that people need mentors to move up in the business world, but since most of the people in high ranking positions are men, and close relationships between men and women in the workplace may be frowned up, it can be hard for a woman to find a mentor. Sebastian Schuh notes that women are still underrepresented in leadership role s, but he has different ideas about why. He thinks it’s because women consistently report lower power motivation than men. While this may be a piece of the puzzle, I don’t think he addresses the full picture very well.In addition to differences in leadership, men and women vary on the axis of sexuality and attitudes towards sex. Jennifer Petersen and Janet Hyde’s meta-analysis on research of gender differences revealed that although men indicated somewhat more sexual experience and permissive attitudes, there were exceedingly minimal gender differences in sexual attitudes and behaviors. Furthermore, these differences decreased with age. However, I think he glosses over many of differences. There are subtleties to it that must be considered.In â€Å"The Orthodox View of Brain Sexual Differentiation† Marc Breedlove, Bradley Cooke, and Cynthia Jordan discuss how the standard view of sexual differentiation of the brain, which is chiefly resulting from work wi th mammals, oversimplifies a vastly complex process of mechanisms derived through natural selection. The spinal nucleus of the bulbocavernosus (SNB) plays an important role in all this with a complex system. It was interesting to see how social factors could take an effect and how plastic and ever-evolving this system could be.One thing is clear from this reading; this SNB system is more multifaceted than previously thought and may be changing well into adulthood. As far as gender differences in aggression, I was not surprised to learn that men are more likely to be engaged in violence than women. Both from personal experience and cultural norms, that seems to fit the model. However, it was interesting to learn that the primary reason for male aggression is mate competition. From a personal standpoint, I don’t find a violent man liable to get into fights more attractive.I’ve certainly seen the type more than once at a bar, or on the streets, and my first instinct is to remove myself from his company and immediate area. On the contrary, that would be a shortcoming. However, from an evolutionary perspective it makes more sense as to protection and fighting for territory. Though there has been much study on the history of sex, biological and anatomical sex differences and social, sexual, and psychological implications of gender differences, psychology of sexuality is a field that is ever-growing and expanding as studies become more daring and social constructs allow for more experimentation and study.Hopefully in the next century, we will see new research leading to greater understanding of gender and sex.

Ethical Decision Making Essay

Abstract Ethics is the branch of philosophy that examines questions of morality, or right and wrong. In this paper we will discuss the philosophical approaches used in ethical decision making. The two approaches that will be elaborated on are the utilitarian approach and the universal approach. Several questions will be addressed, (1) what is the utilitarian and universal approach? (2) How do we use them in the ethical decision making process and (3) examples of how it relate in the field of Criminal Justice? When conflict arises it’s not always possible to decide who is right or wrong; however our moral responsibility is to resolve problems to the best of our ability. The utilitarian and universal theories are two of several philosophical approaches or methods that can be implemented when making these types of decisions (Zalta & Geoff, 2008). The Utilitarian Approach: Utilitarianism is one of the most powerful and persuasive approaches to normative ethics in the history of philosophy. The utilitarian approach to ethical decision making focuses on taking the action that will result in the greatest good for the greatest number of people. It also focuses on the consequences of the course of action and policy, as well as the affects it has on the well-being of the people directly or indirectly impacted by that action or policy. This approach is used to promote the welfare of everybody by maximizing benefits and minimizing harm (Zalta & Geoff, 2008). For instance, when faced with a situation your first thought or question is what should you do? Once you assess the situation then you would apply which ethical decision is the best action to take. If you implement the utilitarian approach you did so with the intent of producing the greatest balance over harm. Utilitarianism offers a relatively straightforward method for deciding the morally right course of action for any particular situation we may find ourselves in. In the criminal justice field this approach can be widely used. To discover what we ought to do in any situation, we first identify the various courses of action that we could perform. Second, we determine all of the foreseeable benefits and harms that would result from each course of action for everyone affected by the action. And third, we choose the course of action that provides the greatest benefits after the costs have been taken into account (Velasquez, Claire, Shanks, & S.J). The Universal Approach: The universal approach to ethical decision making is similar to the Golden Rule. The golden rule is best interpreted as â€Å"Treat others as you want to be treated†. Universalism argues that knowledge can and should be applied to everyone in every similar situation (Williams & Arrigo, 2008). This approach can be taken in two steps. First, determine whether or not a particular action should be applied to all people under all circumstances. Second, decide if you would be willing to have that same rule to you. This approach claims that ethical principles hold for all and not for some, it is for everybody without exception (Williams & Arrigo, 2008). In other words if you act a certain way towards another and are not willing to be treated in that same regard than you are in violation of the universal rule. To apply the universal approach correctly we need to take into consideration the effects our decision making have on other people’s lives. We also have to be able to imagine ourselves in the other person’s shoes on the receiving end of the action. Imagine you are a police officer in pursuit of what seems to be a drunk driver, while in pursuit the drunk driver hits a pregnant woman crossing the street. What do you do, do you stop for her and leave a drunk driver on the road, or do you call the accident in and continue to pursue the drunk driver to keep him from potentially killing himself and others. The utilitarian approach would more likely call for back up and continue after the drunk driver, but if we use this same example and compare it to the universal approach, the question then becomes what would you want done to you. Both philosophical approaches are infused with flaws, the use of â€Å"utilitarian† thinking is not always clear of what form of action should be taken or if the action you took will have a favorable outcome for the majority. It is difficult to judge what decision will supply the best way to respond to a situation. The universal approach unlike the utilitarian bases its decisions on the facts that the action taken is best for everyone regardless of the situation or the difference in people. My choice between the two is somewhat tossed, because my belief is that you should do unto other as you would want done to you, but at the same time my desire to ensure the greatest number of success is important to me as well. Within the Judicial system decisions are made with or without the input of others; however it is our moral obligation to ensure that we make the best ethical decisions that we can, because every decision somehow directly or indirectly affects someone else.

Critical article about LEADERSHIP Essay Example | Topics and Well Written Essays - 2000 words

Critical article about LEADERSHIP - Essay Example The first part of the debate is whether leaders are born innately or if leaders are developed. Some theories point out that some people might be born with the innate ability to command and influence others. This describes what has become known as the Trait theory. With a biological basis, it states that people possess certain traits. Some of these traits in which we are born with make us more suitable leaders than others (Day p262-265). Thus, those with the correct combination of traits will become leaders in society. Also, the Great Man theory states that great leaders will be born when there is a need for them. Others point out that as we develop as humans, our natural leadership abilities require training and fostering. This is the Behavioral theory and it talks specifically how leadership is a learned process rather than an acquired trait. Since leadership can be taught, this allows the person to develop traits that he/she deems will be important in the course of leadership devel opment (Griffin & Moorhead p311-312). It is a combination of both. Rather than have just one theory explain the entire aspect, it is acceptable to take in the fact that either one could be used to describe how leadership skills are created. One of the important concepts to address regarding leadership theory is to evaluate the skills that are essential for leadership. The first and utmost important skill is in communication. Communication skills are necessary for the leader to communicate his/her ideas to his/her subordinates. This is essential if the leader and the followers are going to function together in a cohesive manner. The second important skill of leadership is the power of delegation. As a leader, it is sometimes impossible to cover goals and challenges by yourself. Teamwork and delegation are needed to solve this. Delegation involves a leader giving up some of his/her power or influence in order to ensure that multiple tasks get done. The final essential skill of leaders hip is cultural competency. In the globalized economy, leaders are constantly facing encounters with people of different races, cultures, ideals, etc. As a leader, it might be necessary to work with someone who does not share the same values as you. As a result, you need to learn to have acceptance as well as understanding which are the foundation and underlying themes of cultural competency. The first main theory is that of transactional leadership. Transactional leadership is often seen in the educational and economical context. It relies on the exchange of both punishments and reinforcements in order to attain goals (Chamorro-Premuzic, Tomas p155). In psychology, punishments are meant to decrease a behavior. Positive punishment is when you increase a negative stimulus in order to decrease a certain type of behavior. Negative punishment is when you decrease a stimulus in order to cause a decrease of a certain type of behavior. For example, if an employee is late the manager can ch oose to decrease his salary in an attempt to decrease his tardiness. Reinforcements are meant to increase a behavior which a person has deemed valuable. Positive reinforcement is increasing a stimulus in order to cause an increase in desired behavior. In the educational setting, a professor will give a student who deserves a good grade an â€Å"A† and hopefully this will encourage the increased academic effort put forth by the student.

Programmable Logic Controllers - Assignment Example The RES instruction is used to cancel the SET instruction, hence putting the PLC off. In the contemporary society, electronic devices are used in variety of ways. Electronic devices which make use of microprocessors rely on signals to understand information. Signals are available in two forms, i.e. Digital and analogue. Electronic devices can only understand information that is in digital format, and hence the analogue signals are meaningless in such devices. For this reason, the conversion of analogue to digital signals is essential, especially considering that most real life situations lead to the production of analogue signals. The analogue to digital conversion of information, changes the format of the information, without altering its content. Microprocessors are used for the conversion of the analogue signal to digital. The principle used in the conversion of analogue signals to digital signals by the microprocessor is the voltage variation. The microprocessor used sensors, which detect the incoming analogue signals, and translate them into voltage levels. For instance, the translation of temperature of 0 – 1000c, leads to the assignment of 0 volts to 00c, and 5volts to 1000c. Any value that is above 0volts represents an HIGH, and hence microprocessor can show the actual value, depending upon the number of levels the microprocessor can represent. The resolution of the A/D converter refers to the number of intervals which can be divided from a certain analog input range. Since the interpretation of the analogue input (e.g. temperature) requires assigning of voltage levels, the number of levels which can be represented is determined by the resolution. Resolution of A/D converter is represented in bits, for instance, an n-bit A/D converter has a resolution of 1/2n. The word length, as used in the microprocessors refers to the

English Literature Essay Example | Topics and Well Written Essays - 1250 words - 3

English Literature - Essay Example It is plausible to assert that the main characters’ motivation for viewing in another entity, possibly the best or desired versions of themselves is a consequence of their unremarkable and rather ordinary lives which perhaps do not offer a sense of fulfillment or satisfaction thereby, leaving behind a yearning and longing for wanting more. Accordingly, it is evident that the characters’ psyche is characterized by the presence of doubt, uncertainty and a yet again that sense of discontentedness which is prompted by the onset of anxiety which translates into the emergence of psychological splits. Regardless of the protagonists’ intentions behind their alternative portrayals of the self and their respective identities it can be established that the existence of split identities for a single individual in this case The Narrator and Afonso is also fundamental to the boosting of their self-worth, for perhaps all their lives have been marked by inadequacy and unrequited personal and professional relationships where their mothers, fathers, girlfriends and bosses have been absent in the association or never thought too highly of the protagonists’ or their capabilities to maintain the relationship and let it thrive. However, the question arises that whose approval is more significant for maintaining and advancing the characters’ sense of self-worth? What binds the members of the fictional Fight Club in Palahniuk’s work is a sense of resentment, dissatisfaction and rage which is channeled negatively through activities of vandalism and destruction. However, these are only the personal traits and characteristics that are comparable between each and every member of the alliance. Another aspect of the main characters’ early life which is similar and therefore, reinforces the notion of The Narrator and Tyler Durden – the co-founder of Fight Club being the same person is that of their mutually shared contempt for their fathers.

Tsunami Research Paper Example | Topics and Well Written Essays - 1250 words

Tsunami - Research Paper Example When it reaches shore waters, they rise to form masses of moving water known as â€Å"run-up†. This phenomenon is very many feet high and its variation depends on the strength of striking waves (NOAA, 2009). Normal run-up height is about 30 meters high although there are some extra high run-ups such as that witnessed in Alaska in 1958 which went up to 60 meters high. Run-up rush onto the sea shore and strikes the coastal areas with an intensive, destructive force. Huge earthquakes are able to send tsunami waves across oceans. For instance, recent earthquakes in both Japan and Chile send tsunami waves which struck Alaska, Hawaii, Oregon, California, and Washington causing enormous losses of life and property. Water masses subjected to tsunami waves can take hours to regain stability hence tsunami effects can experienced repeatedly. Tsunami waves occur in phases called first, second and even the third waves. First waves are always less destructive but the second and third may have catastrophic effect depending on the magnitude of causing forces and the position of origin (NOAA, 2009). Tsunamis have very long waves and crest to crest distance may be anywhere between 10 and 2500 kilometers. It travels through the sea at a speed more than 700 km/h. A series of waves travel and arrive at the sea shore at an interval of few minutes. In most cases, tsunami waves are not noticeable like normal sea waves and tides but it possess large amount of energy than other waves. Due to its influence to entire water column, depth of water determines its force (Nelson, 2012). The long wavelengths make the first sign of tsunami waves at the sea shores to be a drawback. Tsunami is caused by submarine earthquake, landslide, volcanic eruption or meteorites (CA, 2009). These causes have common characteristics because they occur suddenly and violently which make them to displace large amounts of water.

Compare & contrast - Essay Example y are worthless and this is mainly due to the fact that teachers no longer care to find out whether their students have received the knowledge they have been taught or not. It looks at the various ways through which students can be motivated to get interested in their studies so that their education can be beneficial not only to them, but also to the society in which they will work. Education is one of the most important things in the world today; in fact, it is considered a basic human right by most international organizations. In this paper, we shall look at two articles with different approaches to education and we shall compare these approaches to each other. In this paper, we shall compare the different approaches that these two authors have suggested as a remedy for filling up the gaps in education both in the workplace and at school. We shall look at the following: an approach to education, failures in the education system, and finally, the actions to be taken to ensure that education is beneficial. Feuer and Sherry have suggested very different approaches to ensure that people get the necessary education to be able to excel in life. Feuer states that there are so many books on sales each having its own approach that it can be confusing for those who would like to learn more about it. He suggests that it is always best to ensure that those people who are learning about sales are taught only the most important points which they may use when doing their work. There is no need to overeducate them because this will only lead to their confusion during the sales process. Sherry, on the other hand, states that teachers are no longer paying attention to their students’ educational welfare and instead tend to pass them along to the next class even though they have not learned anything in the previous class. This results in the failure of the education system because many of those who receive high school diplomas tend to be practically illiterate and this is all
