Sexual Differentiation and its Effects on Sexual Orientation What controls a human's sexual orientation? The long-standing debate of nature versus nurture can be extended to explaining human sexual orientation. Is it biological or environmental? The biological explanation has been gaining popularity amongst the scientific community although it is only based on speculations. It is argued that sexual orientation is linked to factors that occur during sexual differentiation. The prenatal exposure
match their inner identity and spirits as women, or men" (Berdache 1). According to gender expert Carl Bushong, gender is a composition of five different factors. Due to this, he says there can be thousands of different combinations of gender (2). Sexual disorders may have a great deal to do with chromosomal makeup, but they are also rooted in the makeup of the psyche. The first category of Dr. Bushong's theory is genetics. Due to defects in fertilization, fetuses can have a chromosomal pattern of
Sex determination is decided by the 23rd pair of chromosomes commonly known as the sex chromosomes. Males have XY as their 23rd pair and females have XX. A female gamete, the ovum, can only receive only the X chromosome and the male gamete, the spermatozoon can receive either the X or the Y chromosome when meiosis occurs. Therefore the male sperm is responsible for the sex determination of the baby. Example: Figure 1: a Punnet square showing that there is an equal opportunity for a foetus to
are anomalies in the sexual genetic make-up of humans. Three classes of hermaphrodites have been identified: true, female pseudo, and male pseudo. True or mosaic hermaphrodites have a sexual genetic makeup of XXXY as opposed to the normal XX or XY. The individuals with this composition can have genitalia that range from completely male or female to a mixture of both female and male parts. They are usually assigned to the gender they most closely represent (Sex Differentiation Disorders 1). Although
Influence of Parents on Children's Sexual Orientation Do parents influence their children's sexuality? The answer may surprise you: no they do not. It has been found that about 90% of sons of gay fathers are heterosexual (Bailey 124). It was also found that 90% of daughters of lesbian women are also heterosexual (Golombok 4). According to a poll taken by Northwestern University almost 95% of people expect children of homosexual parents to be homosexual themselves (Bailey 125)
As a pediatrician and urologist specifically concentrating on disorders of sexual development (DSD)- “congenital conditions in which the development of chromosomal, gonadal, or anatomical sex is atypical” (Arnold/Saguy, Lecture 11)- every once in a while, a pregnant woman, whose first child is born with congenital androgen hyperplasia (CAH), comes to my office asking for a medicinal point of view on the biological, psychological, and ethical methods of treatment of her second child. Since recent
a side, one must know what a stem cell is. A stem cell is an unspecialized cell characterized by the ability to self-renew by mitosis while in undifferentiated state, and the capacity to give rise to various differentiated cell types by cell differentiation (Stem Cell). There are three types of stem cells in the human body: embryonic, hematoietic, and adult (Lee). Hematoietic stem cells come from the blood of the umbilical cord (Lee). Adult stem cells are taken
Define Gilman’s terms “sex-distinction” and “sex-attraction.” Discuss how you feel (if you do) society today still overemphasizes both terms. Draw on your own experiences or a friend’s experience to give support for your argument. (pages 203-211) In “Women and Economics,” Gilman suggest that humans are the only species in which one sex wholly depends on the other sex economically. Gilman points out that women are fully dependent on men for life’s necessities—her economic status is about her sex
Marketing Assignment-3- Explain the concepts of segmentation, targeting, and positioning and how they are applied in global marketing? Market segmentation is the process of splitting a market of potential customers into groups, or segments, based on distinct characteristics. It is also based on the premise that companies should attempt to identify customers in different countries who share similar needs and wants. The process of it begins with the choice of one or more variables to use as
become a muscle cell, a red blood cell, or a brain cell. There are millions of people who develop some sort of medical condition such as birth defects and cancers every year. These conditions are due to the fact of abnormal cell division and differentiation. Stem Cells have the capability to repair many different types of damaged tissue. The two main types of stem cells scientists use are Adult and Embryonic Stem cells. The embryonic stem cell is the first type of stem cell scientist’s deal with
The possibility to cure Alzheimer, Parkinson’s, AIDS, spinal injuries, and many more diseases and conditions is received by many in the medical world with excitement and anticipation. The discoveries of embryonic stem, ES, cells in 1998 by James A. Thomson, a biologist at the University of Wisconsin, Madison, was a great breakthrough for the medical world, showing great promise in the field of stem cell research. This is because they have the capacity to become any type of cell tissue in the body
As technology stem cell research intensifies, so does the controversy about whether such scientific progress is moral. In the past millennium to today the present stem cell research has become a controversial topic across the world. Stem cells are unspecialized cells that have unique regenerative abilities, allowing them to divide into specialized cell types. Understanding why these processes occur is essential to curing disease. Critics of stem cell research argue that the extraction of embryonic
This paper focuses on the benefits of stem cell research in the medical and nursing field. New technology is always being created to help us understand the way the human body works, as well as ways to help us improve diseased states in the body. Our bodies have the ability to proliferate or regrow cells when damage is done to the cells. Take for example the skin, when an abrasion or puncture to the skin causes loss of our skin cells, the body has its own way of causing those cells to regrow. The
“The concept of differentiation is itself differentiated and refracted through a host of different lenses – intrapersonal, interpersonal, cognitive, affective, behavioural, cultural, and so on” (Cohen et al. 2004, p. 137). This vast range of factors inherent of how teachers plan to support their pupils’ individual needs was also observed in the school where this writer works. However, with it being an educational institution where all pupils are Chinese nationals and English is their second language
Students should experience a sense of ownership when they are able to seek and choose challenging learning experiences (Tomlinson, 2001). In order to provide students with choice at their level of readiness differentiation must occur in the classroom. Author and expert in practical differentiation strategies, Tomlinson (2001), defines a differentiated classroom as one where, “the teacher proactively plans and carries out varied approaches to content, process, and product in anticipation and response
PEST analysis stands for Political, economic, social and technological analysis that describes a framework of macro environmental factors used in the environmental scanning component of strategic management. 2.1.1 Political factors are basically to what degree the government intervenes in the economy. Specifically, political factors include areas such as tax policy, labor law, environmental law, trade law, tariffs, and political stability. Political factors may also include goods and services which
Stakeholder theory Stakeholder theory states that the prime purpose is to maximize shareholder wealth by making a profit in the business (Friedman, 1970). This can be done by focusing the company choice that will benefit the shareholder as the right choice will lead to business success. The company choices that will be looking on are market, technological, legal and environmental. The stakeholder theory also concern on the important on identifying who are stakeholders in a corporation and need to
For decades, biologists have been using stem cells to figure out possible cures for different diseases and even prevent them. Stem cells are cells that can become useable in certain tissues in the body (according to an infant), or tissue cells that are already found in blood, bones, the brain, and skin (in adults or children). Stem cells are being used for patients with lymphoma (begins in the immune system), leukemia (cancer of white blood cells), and other types of blood disorders. Stem cells come
One of the most spoken of topic in the past four decades, are the advancements in genetic engineering. Stem cells were discovered in the mid-1800s and the subject of experimentation in the early 1900s, it’s only been in recent decades that they’ve truly caught the imagination of medical researchers and the public. Today, our understanding of these cells is expanding dramatically, and research has proliferated, as their potential is becoming clearer and clearer. Research into stem cells grew out of
features that are acceptable to customers at the lowest cost, relative to that of competitors. Firms using the cost leadership strategy commonly sell standardized goods or services (but with competitive levels of differentiation) to the industry’s most typical customers. Differentiation: is an integrated set of actions taken to produce goods or services (at an acceptable cost) that customers perceive as being different in ways that are important to them. While cost leaders serve a typical customer
