Researchers have long recognized that subjective perceptions of risk are better predictors of choices over risky outcomes than science‐based or experts’ assessments of risk. More recent work suggests that uncertainty about risks also plays a role in predicting choices and behavior. In this article, we develop and estimate a formal model for an individual's perceived health risks associated with arsenic contamination of his or her drinking water. The modeling approach treats risk as a random variable, with an estimable probability distribution whose variance reflects uncertainty. The model we estimate uses data collected from a survey given to a sample of people living in arsenic‐prone areas in the United States. The findings from this article support the fact that scientific information is essential to explaining the mortality rate perceived by the individuals, but uncertainty about the probability remains significant.  相似文献

Erectile dysfunction frequently occurs with diabetes mellitus. A survey of diabetic men was conducted by anonymous questionnaire to investigate the associations of erectile dysfunction with various predictive factors. A total of 112 diabetic males without an obvious history of erectile dysfunction were available for analyses. The mean age and duration of diabetes were 53.7?±?12.2 years and 10.2?±?8.6 years (mean?±?standard deviation), respectively. The questionnaire included questions on the presence or absence of smoking, hypertension, libido and subjective symptoms of diabetic neuropathy that may be associated with erectile dysfunction. Analysis of the answers to the questionnaire revealed that 40% of the patients complained of erectile dysfunction (erection ‘always insufficient’). Erectile dysfunction was significantly correlated with age (p?=?0.005), but not with duration of diabetes (p?=?0.25), adjusted for age. Erectile dysfunction was also associated with sensory neuropathy and reduced libido, independently of age. The logistic regression analysis revealed that erectile dysfunction was positively associated with reduced libido and age. The odds ratio of erectile dysfunction for reduced compared to unreduced libido was 18.21, suggesting that psychogenic factors have a marked influence on erectile dysfunction. It is concluded that the presence of erectile dysfunction should be considered when symptoms related to diabetic neuropathy are observed; psychological approaches, such as sexual counseling, could be applied for the treatment of erectile dysfunction.  相似文献

The term integrative psychotherapy can have a range of meanings. It can refer to integration between therapeutic approaches grounded in different theoretical frameworks as exemplified in Wachtel’s (Psychoanalysis and behavior therapy: toward an integration. Basic Books, New York, 1977) Psychoanalysis and Behavior Therapy. Many therapists informally practice this sort of integration when, in response to problems and issues presented by the patient, they intuitively borrow from a variety of approaches in their clinical work. Therapeutic integration can also refer to attempts at integration within a single broad therapeutic approach such as psychoanalytic or psychodynamic. This is the direction I will take in this article. My goal in this paper is to contribute to the possibility of integration among different theoretical approaches within psychoanalysis in a delimited area. The delimited area that I will focus on is the tension between an emphasis on interpretation and insight versus an emphasis on the therapeutic relationship as the primary agent of therapeutic change. Rather than an “either-or” position, I will show that integrating theories about both aspects of this process leads to a richer, more complex picture of what happens in psychodynamically-informed therapy.  相似文献

We develop exact inference for the location and scale parameters of the Laplace (double exponential) distribution based on their maximum likelihood estimators from a Type-II censored sample. Based on some pivotal quantities, exact confidence intervals and tests of hypotheses are constructed. Upon conditioning first on the number of observations that are below the population median, exact distributions of the pivotal quantities are expressed as mixtures of linear combinations and of ratios of linear combinations of standard exponential random variables, which facilitates the computation of quantiles of these pivotal quantities. Tables of quantiles are presented for the complete sample case.  相似文献

Despite the well‐documented importance of parental sensitivity for child development, there is a lack of consensus regarding how best to assess it. We investigated the factor structure of maternal caregiving behavior as assessed at 12 months by the Maternal Behavior Q‐Sort (Pederson & Moran) with 274 mother‐infant dyads. Subsequently, we examined associations between these empirically‐derived dimensions and child attachment, assessed in the home and laboratory (final N = 157). Three dimensions of maternal behavior were identified, corresponding fairly closely to Ainsworth's original scales. They were labeled Cooperation/Attunement, Positivity, and Accessibility/Availability. Only Cooperation/Attunement consistently predicted home‐based attachment at 15 months and 2 years, and at comparable strength to the overall sensitivity score, suggesting that this construct may be central to sensitivity. At 18 months, compared to their primarily secure counterparts, different types of laboratory‐assessed insecure attachment were associated with different patterns of maternal behavior. Mothers in avoidant relationships (n = 18) were low on Cooperation/Attunement and Accessibility/Availability, but fairly high on Positivity. Mothers of disorganized infants (n = 11) were Cooperative/Attuned but somewhat less Positive toward, and less Accessible/Available to, their infants. A multidimensional approach to parental behavior may facilitate the identification of parenting precursors of insecure parent‐child relationships.  相似文献

This paper describes the use of a probability sample to survey differential fertility. 475 women were randomly selected from the 1941 Census of Canada to provide tests of the existence of five differentials: income, present age, age by marriage, schooling and distance from a city. The sample was limited to one province and to two contrasting values of each of the five differentials under study. Significant differences are found for the effective distance as well as for age at marriage and schooling. This is taken as signifying that the diffusion of the small-family pattern has a spatial dimension.  相似文献

Although low participation rates have historically been considered problematic in peer nomination research, some researchers have recently argued that small proportions of participants can, in fact, provide adequate sociometric data. The current study used a classical measurement perspective to investigate the internal reliability (Cronbach's α) of peer nomination measures of acceptance, popularity, friendship, prosocial behavior, and overt aggression. Data from 642 participants attending 10 schools were resampled at different participation rates ranging from 5 percent to 100 percent of the original samples. Results indicated that (1) the association between participation rate and Cronbach's α was curvilinear across schools and variables; (2) collecting more data for a given variable (by using unlimited vs. limited nominations, or two vs. one items) was significantly related to higher internal reliability; and (3) certain variables (overt aggression, popularity) were more reliable than others (acceptance, friendship). Implications for future research were discussed.  相似文献

This study assesses selective responding in a single wave of data collection and a four-wave study. Participants were 121 parents of post-institutionalized children, identified as “never responders,” “previous responders,” or “wave 4 responders.” Parents evaluated their adopted child's family, school, peer, and behavioral adjustment. Children (47% male) were 2 to 20 years old (M = 10.79, SD = 4.59) and adopted between 5 and 54 months of age (M = 15.49, SD = 9.94). Within a single wave of data collection, no evidence suggested that selective responding contributes much bias. Over a multi-wave study, however, results may under-represent adjustment difficulties.  相似文献

This study presents the perspective of parents who adopted children internationally and their now adult adopted children regarding the impact of international adoption on their lives. Areas explored include adaptation of the child and family, challenges experienced along the way, influence on various aspects of their lives, parent-child relationship, rewards and regrets associated with the adoption experience, recommendations for those considering international adoptions, and an adjective that would describe their journey. The outcome illuminates the success of international adoptions and the life-changing bond that is formed when parents and children transcend all boundaries to form a family to call their own.  相似文献
