Replication Of Human Pheromones :: Biology Essays Research Papers

Sexual Or Sexist? Replication Of Human Pheromones From the elixer in Love Potion Number Nine to the Orgasmatron in Orgazmo, the media reflect a popular fascination with the idea of an object that can control other people's sexual desires and behaviors. On a similar but dorkier note, I have occasionally heard at Haverford someone attribute a sexual "lucky streak" to the influence of pheromones. In our well-educated but socially awkward mind frame, we have hit on a more promising possibility than magic potions or radar guns. From the Greek for "excitement carrier", pheromones carry chemical messages between members of the same species (2). Present in many animals and often responsible for aspects of mating behavior, the idea of pheromones in humans has in recent years been a subject of interest. The idea of pheromone perception as a "sixth sense" is intriguing, as it means our behavior is influenced by input from outside stimuli that we cannot consciously perceive. Evidence points to the output by and influence on humans of natural ph eromones, and these pheromones are under attempt at imitation by commercial products. What are the possible ramifications of such developments? Experimental evidence also shows differences in the way men and women respond to pheromones, and the possible implications of these differences on gender roles is the aspect of human pheromone research that interests me most. These chemical signals are detected in the vomeronasal organ, or VNO, which is present in the noses of most species of vertebrates. In other mammals, the VNO is located in a longitudinal bulge at the base of either side of the nasal septum (4). Humans lack this bulge marking the position of the VNO, and although there are nerve bundles running from the human VNO to the brain, it is still unclear whether they contain actual sensory neurons or just autonomic nerves. Unlike that in animals, the human VNO does not have an obvious sensory epithelium; however, it contains cells that are considered to be bipolar receptor neurons. The human VNO is thought to be stimulated by airborne chemicals, as opposed to stimuli dissolved in mucus (3). Although most exploration of the possibilities of human pheromone perception has happened recently, scientists have known about the human VNO since 1703, when Dutch surgeon Roysch discovered it in the nose (2). Since then the VNO has been commonly thought to be present only in fetuses, disappearing over the course of prenatal development.

Cognitive Design Essay

A Thousand Splendid Suns by Khalid Hosseini is seen through the eyes of two young female protagonists, who have a strong and well-developed character. In the novel, the author shows their hardship, their lives in a hopeless society, Afghanistan, and how throughout their life they face cruelty and vulnerability. The author portrays the experiences of the two Afghan women, Mariam and Laila, who live in a society where women are mistreated. Mariam’s character is described as a quiet and thoughtful girl who questions the society and dreams of a luxurious life. She experiences physical and mental abuse from almost every person in her life and is brought up in an isolated environment by a bitter mother who puts her down. For instance, in the beginning of the novel Nana, Mariam’s mother, says: â€Å"You are a clumsy little harami† (Hosseini, 4). This very word â€Å"harami† helps the reader to analyze the struggles of an illegitimate child. Nana also prepares Mariam to expect nothing from men: â€Å"Like a compass needle that always point north, a man’s accusing finger always finds a woman. Always †¦. Mariam† (Hosseini, 7). This is also used to foreshadow Mariam’s husband, Rasheed, a cruel, abusive and hot tempered man, who physically and verba lly abuses Mariam after marriage. Although Laila was also brought up in the same society as Mariam, her character is stronger as compared to Mariam’s. She has a strong desire to use her intelligence and education to improve the society and as her father, tells her: â€Å"Marriage can wait, education cannot†¦ You can be anything you want†¦ Because a society has no change of success if its women are uneducated†¦ No chance† (Hosseini, 114). The characters personality evolves over time, and this helps to analyze the tragic themes of the novel which are oppression, hope, and internal strength of women. The ability for any individual to imagine to endure the pain and sacrifices that Mariam and Laila endured are overwhelming. Yet the authors’ description of the characters makes it easy to analyze them to a great depth.

Help Others Too Allison Hepburn 12/10/2018 English 010 @3pm Help Others Too Award Winning movie â€Å"The Help† based in Jackson, Mississippi during the 1960’s is primarily about the relationships between black maids and their white employers. It starts with Skeeter, played by Emma Stone, A young white female who is a recent college graduate trying to pursue her dream as a writer. Skeeter is Surrounded by friends and family who have a sense of â€Å"white entitlement†.   She secretly befriends two black nannies† Aibileen† played by Viola Davies and â€Å"Minnie† played by Octavia Spencer learning abo ut their time working in white households and puts their stories in her book, giving them a voice. Many of the nanny’s stories included taking care of white family’s children while the white didn’t, having to go to the restroom outside in the rain, not eating at the same table and so much more hardships.   Throughout the movie you will see the struggles that many African Americans had to endure in their everyday lives in the 1960s.Some moments hard to watch, some are definitely sad, but also has spurts of humor that will make you laugh. This was the time when the Jim Crow Law was in effect.   Jim Crow was the name of the racial segregation system, which operated mostly in southern and border states, between 1877 and the mid-1960s(Pilgrim2).It was a way of life(Pilgrim2). Under Jim Crow, African Americans were given the status of second-class citizens. In the movie â€Å"The Help† there are many scenes where the nannies in the white household are treated less than and gives you an actual idea of how life was for them when this was in effect. Jim Crow helped to make anti-black racism appear right Pro segregation politicians gave persuasive speeches on the great danger of integration: the destruction of the purity of the white race (Pilgrim2). The Jim Crow system was based on the following beliefs: whites were superior to blacks in all important ways, including but not limited to intelligence, morality, and civilized behavior; relationships between blacks and whites would produce a mongrel race which would des troy America; treating blacks as equals would encourage interracial relationships between men and women; any activity which suggested social equality encouraged interracial sexual relations; if necessary, violence must be used to keep blacks at the bottom racial level (Pilgrim2) . The following Jim Crow etiquette norms show how inclusive and pervasive these norms were: A black male could not offer his hand (to shake hands) with a white male because it implied being socially equal. Obviously, a black male could not offer his hand or any other part of his body to a white woman, because he risked being accused of rape. Blacks and whites were not supposed to eat together. If they did eat together, whites were to be served first, and some sort of partition was to be placed between them. Under no circumstance was a black male to offer to light the cigarette of a white female that gesture implied intimacy. Blacks were not allowed to show public affection toward one another in public, especially kissing, because it offended whites. Jim Crow etiquette required that blacks were introduced to whites, never whites to blacks. For example: Mr. Peters (the white person), this is Charlie (the black person), that I spoke to you about. Whites did not use courtesy titles of respect when referring to blacks, for example, Mr., Mrs., Miss., Sir, or Maam. Instead, blacks were called by their first names. Blacks had to use courtesy titles when referring to whites, and were not allowed to call them by their first names. If a black person rode in a car driven by a white person, the black person sat in the back seat or the back of a truck. motorists had the right-of-way at all intersections. (Pilgrim2). Many of these disturbing laws you will see during this movie. As you could imagine these nannies were very hesitant about telling their stories about these white families and what they have seen and went through while working there, worrying they might get into trouble or something might happen to them. One of the best parts about this film is you have Skeeter (a white woman) who is genuinely trying to help these women and doesn’t seem to look at them as any different or any less then herself, nor does she care about what her other friends who don’t approve think. The friendship and trust that they build Is amazing to watch and really captures your heart. This Film had many amazing top Actresses such as; Emma Stone, playing the character Skeeter, Won 1 Oscar. Another 58 wins 120 nominations, playing a humble character who wants to give these women a voice (IMDB); Viola Davis an Oscar winner 84 wins and 111 nominations, including this movies, a brave black woman telling her hardships for the first time to a white person (IMDB); Octavia Spencer Won 1 Oscar. Another 32 wins 65 nominations playing a spit fire Nannie taking life into her own hands (IMDB). These Actresses really brought this movie to life and gave amazing performances that just might bring a tear to your eye. This movie gives you the perfect view of the different situations that are at the same time educational to people who want to know exactly how it was like be an African American in the southern states during the 1960’s.And a friendship and relationship that was surprising to many at the time.
