This study involves the development and initial validation of a questionnaire measuring the propensity for sexual inhibition and excitation in men: the Sexual Inhibition & Sexual Excitation Scales (SIS/SES). The underlying theoretical model postulates that sexual response and associated behavior depend on dual control mechanisms, involving excitatory and inhibitory neurophysiological systems. The scales and their discriminant and convergent validity and test‐retest reliability are described. In a sample of 408 sexually functional men (mean age = 22.8 years), factor analyses identified three higher‐level factors: two related to sexual inhibition and one to sexual excitation. Multigroup Confirmatory Factor Analyses revealed that the factor structure provided an acceptable fit to the data obtained in a second (N = 459; mean age = 20.9 years) and third (N = 313; mean age = 46.2 years) sample of men, with similar distributions and relationships with other measures. Theoretical issues and areas for further research, including male sexual dysfunction and risk taking, are discussed.  相似文献

ABSTRACT

There are several models for the delivery of etherapy on the Internet. This article presents a case study of one model, the LivePerson website. The model is based on a privately owned infrastructure through which etherapy is practiced by licensed counselors using chat or e-mail for service delivery. A content analysis of the website is presented, including policies, number of consumers, consumer ratings, and therapists’ degrees, licensure, age, sex, race, fees, and languages offered. In addition, the experiences of one LivePerson practitioner are presented to highlight methods, processes, and ethical concerns. This case study of the LivePerson model for service delivery highlights many of the benefits and concerns previously discussed in the literature related to etherapy. In addition, concerns are raised that there may be some conflict of interest when ethical standards of practice are delivered within the context of a profit-making company.  相似文献

The problem of adolescent substance use has been examined extensively. Beyond simple prevalence estimates, however, little research has been conducted on substance use in the school context. The present investigation was an in‐depth study of students' attitudes and behaviors regarding alcohol and marijuana use during the school day. Based on a representative sample of 1123 high school students, this study assessed the frequency of alcohol and marijuana use at school among demographic subgroups, the accessibility of drugs in school, and students' perceived consequences of being caught using drugs in school. The results showed that male and Hispanic students had higher levels of drug use at school than female and white students, respectively; that school drug use increased with age, and that alcohol and marijuana were easily obtained and used on school grounds. A large percentage of students were not aware of the specific actions taken in their schools to punish drug use. The need for additional research on school‐related drug use is emphasized.  相似文献

Implementation of JIT methods often begins in an assembly department with the introduction of kanban. Only when the implementation program begins in the fabrication areas supplying the assembly department do the most serious problems with JIT arise. The farther back in the supply chain JIT is implemented, the harder problems become, especially in the management of outside suppliers such as foundries where economics still requires the batching of jobs. Faced with supplying a tractor assembly line, department 500, a producer of heavy cast iron transmission cases using transfer lines and MRP, implemented kanban not only to supply the assembly area, but also back to their own supplying foundries. The results were positive and suggest a need for creativity in JIT implementation rather than a strict adherence to a cookbook approach.  相似文献

An increase in social pathologies is a key feature in indigenous populations undergoing transition. The Greenland Inuit are a large indigenous population constituting a majority in their own country, which makes it possible to investigate differences within the population. This led us to study gambling behavior and problem gambling among Greenland Inuit in relation to the ongoing social transition and traumatic events during childhood. A large representative cross-sectional study was conducted among Greenland Inuit (n = 2,189). Data was collected among adults (18+) in 9 towns and 13 villages in Greenland from 2005 to 2010. Problem gambling, gambling behavior and traumatic childhood events were measured through a self-administered questionnaire. The lie/bet screen was used to identify past year and lifetime problem gambling. Social transition was measured as place of residence and a combination of residence, education and occupation. The lifetime prevalence of problem gambling was 16 % among men and 10 % among women (p < 0.0001); and higher in towns (19 %) compared to the capital of Nuuk (11 %) and in villages (12 %) (men only, p = 0.020). Lifetime problem gambling was associated with social transition (p = 0.023), alcohol problems in childhood home (p = 0.001/p = 0.002) and sexual abuse in childhood (women only, p = 0.030). A comparably high prevalence of lifetime problem gambling among Greenland Inuit adds problem gambling to the list of social pathologies in Greenland. A significant association between lifetime problem gambling, social transition and traumatic childhood events suggests people caught between tradition and modern ways of life are more vulnerable to gambling problems.  相似文献

This paper presents the results of a survey on the use of computer-based models in the broad areas of planning and strategy formulation in UK companies. This survey updates and complements other recent surveys, which exclusively considered the use of corporate models, and shows a continued increase in the numbers of these models in use. In particular, models in the following broad categories were examined: forecasting, marketing, personnel, production and models of ‘one-off’ situations, as well as corporate and financial models. For such models the paper includes details of: frequencies of occurrence and relationship to company size; professional roles of the model-builders and users respectively; frequencies of use. In these and more subjective ways, the survey attempts to assess the place and value of computers in planning.  相似文献
