Testosterone and Infidelity Essay -- Extramarital affair, Infidelity,

A man has been married to his wife for seven years. The couple has two beautiful children, a fabulous home, and appear to have the perfect marriage. After the husband leaves work one afternoon, he decides to stop in at the local bar. The man sits at a table in the corner of the room. Not long after his arrival, a woman approaches him. She asks the man if she can join him at his table. The two seem to have quite a bit in common and enjoy each other’s company. The woman asks if he would like to go back to her apartment. He has not had a fight with his wife today. In fact, she surprised him with a love note in his briefcase. Their sex life is enjoyable, frequent, and without complaint. The couple is not currently having financial problems. Despite this, why did the man decide to leave with a stranger and cheat on his wife? A great deal of research has been carried out on the topic of infidelity. Marital therapists have reported that more than half of the couples t hey counsel are in therapy as a result of infidelity (Atkins, Jacobson citation). Therapists also consider an extramarital affair as, â€Å"one of the most damaging relationship events and one of the most difficult problems to treat in couples therapy† (whisman predicting sexual infidelity†¦). Some therapists estimate that 50% to 65% of couples seek help after an incident of infidelity in their relationship (Atkins, Jacobson & Baucom). Identifying the reasons for this problem are essential to the success of its reduction. Infidelity is not a new phenomenon. However, there was little research on the topic until the late 1970’s (Drigotas & Barta, 2001). Numerous factors have been examined while trying to determine the root cause for extramarital relationships a... ...irections and implications. In a future study, a satisfaction questionnaire could be included to examine a participant’s current marital satisfaction prior to exposure to their condition. A study should be conducted using an older sample of male participants in order to see if results would be different as a result of the decreased levels of testosterone in that age group. In addition, future researchers should consider investigating homosexuality, testosterone, and infidelity. There is no research that address homosexuality, testosterone. and infidelity. As such, future research should explore these aspects. Research dedicated to biological reasons for infidelity is an important and necessary contribution to reduce the worldwide epidemic of divorce. Understanding the effect (effect or affect?) testosterone has on infidelity is another step in this process.

Athenian audience Essay

Athenian audience with the references made to Athenian hypocrisy and the challenges and questions he raised on some of the moral issues of the time and the questions that he asked in his plays were sometimes ill received such as the role of women etc. Despite this, Euripides did win the tragedy prize with ‘Hippolytus’ and is revered as a great playwright in present day drama. From some of the female characters that Euripides develops in his plays, one could assume that Euripides was a misogynist. However, it is wrong to say that all of his female characters are wicked and evil; Euripides has created some wonderful and interesting female characters as well as the wicked ones. Perhaps ‘The Assembly Women’ actually had wrong motive for their revolt! In ‘Alcestis’, the title character, the wife of Admetus (the King of Pherae) sacrifices herself for her husband’s life. A most noble act and Euripides portrays her character, as the model of what a Greek wife should be: completely and utterly devoted to their husband to the extent of dieing for the man that supports them. The Greek audience and modern alike will like Alcestis, as she is a sweet natured and noble woman. She most certainly would have won the hearts of the Greek audience. As she is such a noble character and the measure of her kindness toward her husband is so great, Euripides had to bring her back. So the heroic Heracles wends his way to Hades’ kingdom and brings her back. In ‘Electra’, again the title role, at the beginning of the play, comes across as a very sorrowful young woman. She has cut her hair out of mourning for her murdered father, Agamemnon. He was murdered by her mother, Clytemnestra, as he had to sacrifice their daughter and then brought home a concubine (Cassandra). When Agamemnon did get home, Clytemnestra had fallen in love with Aegisthus. Therefore, so far in the play, Electra comes across as a woman very much devoted to her father and hates her mother for murdering him. So far so justified. However, when she happens to meet her brother, Orestes, she convinces him to kill their mother. At this point she comes across as a very wicked conniving young lady. It seems as though she had been waiting for Orestes return to make him do this. When Orestes has doubts over killing Clytemnestra, she bullies him into doing it. She knew the result she wanted to get and she got it. Clytemnestra, if you haven’t read or seen Aeschylus’ ‘Agamemnon’, comes across as a less conniving woman than her daughter. She comes across as a very powerful and domineering woman. She arrives in the play in a chariot and commands the slaves to help her down. She is very aware of her class and position and will not back down from her decision to murder Agamemnon and regards it as the right thing to do. In this sense we must respect her for sticking by her decision and understand that Agamemnon did kill their daughter and come back with a concubine. In a very slight way, she is justified. Therefore, Euripides has created in Electra a very complicated character. We as the audience or readers assume that she had been planning her revenge on her mother for some time and was just waiting for Orestes return to enact it. Before this point however, we can sympathise with her loss of a father and the pain that she must be going thorough to have the knowledge that it was her mother who murdered him. Clytemnestra, from this play, comes across a woman who sticks by her decision and who in speech ha the capacity to justify and handle herself well. Euripides has created two complicated female characters and in his portrayal of them has shown no signs of his rumoured misogyny. Euripides creates one of the greatest roles for any actress to play in ‘Hecabe’. The title role is not the aforementioned feet of extraordinary characterisation. However, Hecabe as a character is very interesting. The audience comes away not knowing what to think of her. She begins the play as a woman who has endured such a lot of pain as the former Queen of the now sacked citadel of Troy. She has reached the limit of endurance and collapses in sorrow. She has lost her entire family to a war over one woman, the infamous Helen. At the end of the play, however, she literally snaps from a grief stricken widow to a raving savage. She has Polymestor blinded and enjoys the gruesome description of the event and the sounds. According to legend, Hecabe turns into a dog due to her extreme torment that results into madness. This is what Polymestor tells her at the end of the play when his blind by her decision. The character this section opened with by praising is Polyxena. She is Hecabe’s daughter and Euripides develops her character beautifully. Odysseus informs Hecabe that her daughter must be sacrificed to the deceased Achilles. Without shedding a tear, Polyxena, heroically goes with Odysseus to accept her fate. As she is taken to the tomb of Peleus (Achilles father), Greek soldiers hold her and Achilles’ son gets ready with his sword to kill or to sacrifice her. She asks not to be held and the soldiers are taken away. She then tears her clothes off to the wait and bravely speaks and awaits the sword to be thrust into her chest. Euripides in this play has created two memorable female characters. The brave and heroic Polyxena and the complicated Hecabe. Again, no sign of any misogyny on Euripides part here, in fact the opposite in Polyxena’s case. Creating a heroic woman is no mean feet in Ancient Greece and her character must have been received well as she is incredibly strong of character and of heart. Another great female character in Euripidean literature is Heracles wife Megara in the play ‘Heracles’. The play tells of how Hera (Queen of the gods, married to Zeus, who’s father to Heracles) turned Heracles mad and in his madness killed his three sons and his wife Megara. This then lead him to go to the Delphic Oracle that told him to be a slave to Eurytheus thus leading to his infamous twelve labours. Anyhow, Megara, at the beginning of the play, thinks that she is a widow and is a vulnerable woman who has to be strong for her three young sons. However, Heracles actually is not dead and comes home to them in Thebes. He is then turned mad by Hera and shoots two of his sons with arrows in his madness. Megara takes the last son and locks herself in room but Heracles breaks in and shoots them both with one arrow.

Bohr Model of the Atom - Overview and Examples

The Bohr Model has an atom consisting of a small, positively-charged nucleus orbited by negatively-charged electrons. Heres a closer look at the Bohr Model, which is sometimes called the Rutherford-Bohr Model. Overview of the Bohr Model Niels Bohr proposed the Bohr Model of the Atom in 1915. Because the Bohr Model is a modification of the earlier Rutherford Model, some people call Bohrs Model the Rutherford-Bohr Model. The modern model of the atom is based on quantum mechanics. The Bohr Model contains some errors, but it is important because it describes most of the accepted features of atomic theory without all of the high-level math of the modern version. Unlike earlier models, the Bohr Model explains the Rydberg formula for the spectral emission lines of atomic hydrogen. The Bohr Model is a planetary model in which the negatively-charged electrons orbit a small, positively-charged nucleus similar to the planets orbiting the Sun (except that the orbits are not planar). The gravitational force of the solar system is mathematically akin to the Coulomb (electrical) force between the positively-charged nucleus and the negatively-charged electrons. Main Points of the Bohr Model Electrons orbit the nucleus in orbits that have a set size and energy.The energy of the orbit is related to its size. The lowest energy is found in the smallest orbit.Radiation is absorbed or emitted when an electron moves from one orbit to another. Bohr Model of Hydrogen The simplest example of the Bohr Model is for the hydrogen atom (Z 1) or for a hydrogen-like ion (Z 1), in which a negatively-charged electron orbits a small positively-charged nucleus. Electromagnetic energy will be absorbed or emitted if an electron moves from one orbit to another. Only certain electron orbits are permitted. The radius of the possible orbits increases as n2, where n is the principal quantum number. The 3 → 2 transition produces the first line of the Balmer series. For hydrogen (Z 1) this produces a photon having wavelength 656 nm (red light). Bohr Model for Heavier Atoms Heavier atoms contain more protons in the nucleus than the hydrogen atom. More electrons were required to cancel out the positive charge of all of these protons. Bohr believed each electron orbit could only hold a set number of electrons. Once the level was full, additional electrons would be bumped up to the next level. Thus, the Bohr model for heavier atoms described electron shells. The model explained some of the atomic properties of heavier atoms, which had never been reproduced before. For example, the shell model explained why atoms got smaller moving across a period (row) of the periodic table, even though they had more protons and electrons. It also explained why the noble gases were inert and why atoms on the left side of the periodic table attract electrons, while those on the right side lose them. However, the model assumed electrons in the shells didnt interact with each other and couldnt explain why electrons seemed to stack in an irregular manner. Problems with the Bohr Model It violates the Heisenberg Uncertainty Principle because it considers electrons to have both a known radius and orbit.The Bohr Model provides an incorrect value for the ground state orbital angular momentum.It makes poor predictions regarding the spectra of larger atoms.It does not predict the relative intensities of spectral lines.The Bohr Model does not explain fine structure and hyperfine structure in spectral lines.It does not explain the Zeeman Effect. Refinements and Improvements to the Bohr Model The most prominent refinement to the Bohr model was the Sommerfeld model, which is sometimes called the Bohr-Sommerfeld model. In this model, electrons travel in elliptical orbits around the nucleus rather than in circular orbits. The Sommerfeld model was better at explaining atomic spectral effects, such the Stark effect in spectral line splitting. However, the model couldnt accommodate the magnetic quantum number. Ultimately, the Bohr model and models based upon it were replaced Wolfgang Paulis model based on quantum mechanics in 1925. That model was improved to produce the modern model, introduced by Erwin Schrodinger in 1926. Today, the behavior of the hydrogen atom is explained using wave mechanics to describe atomic orbitals.
