The stigmatization of smokers: an empirical investigation

This study examines the social stigmatization of tobacco smokers, i.e., the extent to which smokers are seen as discredited persons. A representative sample of residents of a major Canadian city was interviewed. Clear evidence of an unfavorable stereotype of smokers was found. The ex-smoker enjoys a positive image, but one which is slightly less favorable than that of someone who has never smoked. A majority of non-smoking respondents preferred non-smokers in roles in which the role incumbents were likely to be in close proximity. Friendship networks and marital relationships tended to be segregated along lines of smoking behavior. Sociodemographic and attitudinal correlates of anti-smoker attitudes are explored. The implications of stigmatization for changing smokers' behavior are examined.     

论高海拔地区人类生殖能力的研究:回应霍夫

霍夫的评论表明,那些叙述高海拔缺氧影响人类生育力和生殖能力的文献中弥漫着方法论和概念的迷雾.我们去年的文章主题也谈到了这一点(见<美国人类学家>85:28-49,1983).我们的论文尽力阐述了喜马拉雅山脉的高海拔地区,藏语族群中普遍存在的不同生育力水平,是与某些文献的报道一致的.     

A stepwise discrete variable selection procedure

A stepwise variable selection procedure for multinomial discrimination is presented and discussed. Based upon the work of Kullback and Hills, stopping rules are proposed and illustrated for a set of data on communication buyer behavior.     

Risk Factors of Sexual Harassment by Peers: A Longitudinal Investigation of African American and European American Adolescents

The present research explores risk factors for, and longitudinal associations of, sexual harassment by peers during adolescence. Eight‐hundred and seventy‐two African American and European American adolescents (65.4% African American, 51.1% females) were assessed during the summer after the eighth grade (mean age=14.2 years) and then again in the 11th grade (mean age=17.1 years). At the first assessment, adolescents were asked about their experiences with sexual harassment, their psychological reactions to sexual harassment, and also about their peer relationships, perceived pubertal timing, problem behavior, and mental health. At the second assessment, adolescents reported on their problem behavior and mental health. In general, youth who associated with peers who were involved in problem behavior were at risk for victimization. Among females, those who perceived themselves to be experiencing early pubertal development were also at risk. Additionally, for some adolescents, sexual harassment predicted later adjustment difficulties.     

Cancer risk estimation for mixtures of coal tars and benzo(a)pyrene.

Two-year chronic bioassays were conducted by using B6C3F1 female mice fed several concentrations of two different mixtures of coal tars from manufactured gas waste sites or benzo(a)pyrene (BaP). The purpose of the study was to obtain estimates of cancer potency of coal tar mixtures, by using conventional regulatory methods, for use in manufactured gas waste site remediation. A secondary purpose was to investigate the validity of using the concentration of a single potent carcinogen, in this case benzo(a)pyrene, to estimate the relative risk for a coal tar mixture. The study has shown that BaP dominates the cancer risk when its concentration is greater than 6,300 ppm in the coal tar mixture. In this case the most sensitive tissue site is the forestomach. Using low-dose linear extrapolation, the lifetime cancer risk for humans is estimated to be: Risk < 1.03 x 10(-4) (ppm coal tar in total diet) + 240 x 10(-4) (ppm BaP in total diet), based on forestomach tumors. If the BaP concentration in the coal tar mixture is less than 6,300 ppm, the more likely case, then lung tumors provide the largest estimated upper limit of risk, Risk < 2.55 x 10(-4) (ppm coal tar in total diet), with no contribution of BaP to lung tumors. The upper limit of the cancer potency (slope factor) for lifetime oral exposure to benzo(a)pyrene is 1.2 x 10(-3) per microgram per kg body weight per day from this Good Laboratory Practice (GLP) study compared with the current value of 7.3 x 10(-3) per microgram per kg body weight per day listed in the U.S. EPA Integrated Risk Information System.     

College students' definitions of social and problem drinking

College students (N = 276) completed surveys describing two common drinking situations. One scenario described a student alone in an apartment after a weekday class; the other, the same student at a weekend party. Sex of the drinker in the scenario was systematically varied. Students estimated the number of drinks a social drinker and a problem drinker would have in each situation. Results indicated that: 1) definitions of social and problem drinking are strongly influenced by drinking context, and 2) male and female subjects estimated that problem drinkers of the opposite sex drank more than problem drinkers of their own sex. Problem drinkers were regularly estimated to consume three to four more drinks than the subject would in the same situation. Implications for education and prevention are discussed.     

To Tell or Not to Tell: The Disclosure of Events in the Therapist's Life to the Patient

Happy or disturbing events may occur in a therapist's life during the course of treatment that intrude on the therapeutic process whether or not their true nature is disclosed to the patient. Therapists are not immune from experiencing acute, chronic, and even terminal illnesses, divorce, remarriage, adopting a child, mourning the death of a parent or significant other, or major accomplishments. In many instances such events affect the treatment process by disrupting appointments, necessitating sudden absences, restricting a therapist's emotional availability and physical stamina, or altering the therapist's mood and affect. In other instances, patients may be aware of such events, at least unconsciously, because of subtle changes in the therapist. Drawing on self psychology and intersubjectivity this paper explores the reasons for therapist self-disclosure of these events based on an assessment of the patient's developmental needs and the nature of the transference. It will discuss ways of making such disclosures therapeutic.     

Delivery Pain and the Development of Mother—Infant Interaction

This study examined delivery pain as a possible risk factor for the development of mother‐infant interaction. Eighty‐one mothers completed the Pain Catastrophizing Scale, the State‐Trait Anxiety Inventory, and the Edinburgh Postnatal Depression Scale. A retrospective evaluation of labor pain was performed using the Visual Analog Scale at 2 days postpartum. Six weeks after birth the mothers were visited at home, completed measures of anxiety and depression, and were observed during a free play session with the infant. The mother's tendency to catastrophize pain predicted lower levels of mother‐infant reciprocity at 6 weeks, controlling for maternal age, education, parity, epidural analgesia, pain perception, anxiety, and depression. Trait anxiety was related to lower maternal sensitivity. The mother's tendency to catastrophize pain was discussed in relation to the personality trait of exaggerated emotional perception of pain and its potential interference with the formation of the mother‐infant relationship.
