Problem 63

Assume that atoms are hard spheres, and use the metallic radius of 186 pm for Na to estimate the volumes of one Na atom and of one mole of Na atoms. How does your result compare with the atomic volume found in Figure 9-1? Why is there so much disagreement between the two values?

Step-by-Step Solution:
Step 1 of 3

Sexual Variants and Dysfunctions 3/29/16 Sociocultural Influences • Sexual “standards” of one’s culture tend to drive what is considered acceptable or not • Examples o Abstinence Theory (1800s) o Ritualized homosexuality in the Sambia Tribe (only between males) • Some sexual standards are culturally consistent o Men: greater emphasis on partner’s attractiveness o Taboos against incest • Kinsey’s research (1950s): developed a scale that looks at people’s sexual orientation o 37% of males reported engaging in some kind of sexual activity at least once o Comparable numbers among women o 7 point scale § 0: entirely heterosexual § 7: entirely homosexual • Sexual Minorities o Kinsey: 10% homosexual, 37% men have at least one experience o Removed from DSM in 1973 o “Homosexuality” is often not a preferred term to refer to people who identify as gay, queer, or lesbian o By 2010, majority of Americans view same-sex relations between adults to be morally acceptable o 2015 Nature twin study revealed 5 DNA markers associated with sexual orientation o Epigenetic markers (chemical changes to DNA that affect how genes are expressed, but not the information they contain) o An algorithm they developed based on the 5 epi-marks could correctly predict the sexual orientation of men in the study 67% of the time • History of sex-related legislation in the U.S. o As late as 1970s, gay men/lesbians not allowed to have a driver’s license in Connecticut o Contraceptives among MARRIED couples were banned until 1965 in some states o As late as 2003, sodomy was illegal between consenting adults in some states (including Alabama) o Alabama sex education: “homosexuality is not a lifestyle acceptable to the general public and homosexual conduct is a criminal offense under the laws of the state” • Sexuality in the U.S.A. o Barriers to conducting sex research (example) § Five-year study of sexual behavior in 20,000 adolescents was funded by National Institutes of Health § Congress found out about the study and pushed legislation through to revoke funding § Result à we don’t have good info on sexual functioning in adolescents o Fantasies, interest and behavior are not synonymous Paraphilia vs. Paraphilic Disorder • Paraphilias (fetishism): unusual sexual interests o Not necessarily a disorder o Prevalence for paraphilias is unknown à people are reluctant to disclose, funding issues • Paraphilic Disorder: unusual sexual interests that cause harm o Can have compulsive quality • RULE: distress or victim Paraphilic disorder • Paraphilic Disorder o 8 disorders characterized by recurrent, intense sexually arousing fantasies, sexual urges, or behaviors that generally involve nonhuman objects, the suffering of humiliation of oneself or partner, or children or other non- consenting persons o Fetishistic Disorder § Fantasies, urges, or behaviors involving inanimate objects or highly specific focus on non-genital body parts to obtain sexual gratification § Must cause significant distress or impairment § Examples: undergarments, shoes, feet o Transvestic Disorder § Heterosexual men- fantasies, urges, or behaviors involving cross- dressing § Must cause significant distress or impairment • Not a drag queen § 3% of men have engaged in some cross-dressing; however, most do not meet a diagnosis • Most (83%) are married • Keep cross-dressing secret, or try to • 87% are heterosexual o Voyeuristic Disorder § Fantasies, urges, or behaviors involving the observation of an unsuspecting person who is undressing or engaging in sexual activity – aka “peeking toms” § Distress/impairment OR acted upon such urges with a non- consenting person § Often no resulting criminal behavior § Why not just use pornography • Most likely lacks the excitement associated with watching someone unsuspecting o Exhibitionistic Disorder § Fantasies, urges, or behaviors involving exposure of one’s genitals to others in inappropriate circumstances and without consent § Distress/impairment OR acted upon such urges § Element of “shock” of the unsuspecting person is arousing to such individuals • Must experience arousal § Commonly co-occurs with voyeurism o Sexual Sadism Disorder § Fantasies, urges, or behaviors involving the infliction of psychological or physical pain on another individual § Themes- dominance, control, humiliation § Distress/impairment OR acted upon such urges with a non- consenting person § Serial killers – are often “extreme” sadists o Sexual Masochism Disorder § Fantasies, urges, or behaviors involving the real act of being humiliated, beaten, bound, or otherwise made to suffer § Causes clinically significant distress/impairment § 5-15% of people enjoy this voluntarily § Autoerotic asphyxia: “self-strangulation” – leads to 500-1,000 accidental deaths/year o Frotteuristic Disorder § Fantasies, urges, or behaviors involving touching or rubbing against a non-consenting person § Distress/impairment OR acted upon such urges § Typically begins age 15-25 § Typically live in big cities where it’s much more crowded and less obvious if you’re rubbing up on someone § Often a gradual decline in frequency of such behaviors or urges o Pedophilic Disorder § Fantasies, urges, or behaviors involving the sexual activity with a pre-pubertal child § Distress/impairment OR acting upon urges § Perpetrator is at least 16 years old and at least 5 years older than the victim § Victims can be male or female § Hebophilia: having fantasies, urges or behaviors involving adolescents o Pedophilic Disorder vs. Child sexual abuse § Pedophilic disorder à sexual interest in children (believed to be inborn, not a choice) § Child sexual abuse à acting on these interests (is a crime)
