Studies of subtypes of DSM-IV attention-deficit/hyperactivity disorder (ADHD) have provided inconsistent support for the discriminant validity of the combined type (ADHD-C) and predominantly inattentive type (ADHD-I). A large sample of children and adolescents with ADHD (N?=?410) and a comparison group without ADHD (N?=?311) were used to test the internal and external validity of sluggish cognitive tempo (SCT), a dimension characterized by low energy and sleepy and sluggish behavior. SCT scores were then incorporated in analyses of ADHD subtypes to test whether the discriminant validity of ADHD-C and ADHD-I could be improved by including SCT symptoms as part of the criteria for ADHD-I. Factor analyses of parent and teacher ratings indicated that six SCT items loaded on a factor separate from symptoms of ADHD and other psychopathology, providing important support for the internal validity of SCT. The external validity of SCT was supported by significant associations between SCT and measures of functional impairment and neuropsychological functioning when symptoms of ADHD and other psychopathology were controlled. However, contrary to initial predictions, high levels of SCT did not identify a subgroup of ADHD-I that was clearly distinct from ADHD-C. Instead, the current results suggest that DSM-IV inattention and SCT are separate but correlated symptom dimensions that are each independently associated with important aspects of functional impairment and neuropsychological functioning. 相似文献

The importance of public confidence in scientific findings and trust in scientists cannot be overstated. Thus, it becomes critical for the scientific community to focus on enhancing the strategies used to educate future scientists on ethical research behaviors. What we are lacking is knowledge on how faculty members shape and develop ethical research standards with their students. We are presenting the results of a survey with 3,500 research faculty members. We believe this is the first report on how faculty work with and educate their PhD students on basic research standards. Specifically, we wanted to determine whether individual faculty members, who are advisors or mentors, differ in how they implemented components of responsible conduct of research (RCR) with their PhD students. Mentors were more likely than advisors or supervisors to report working with all of their PhDs, who graduated in the last 5 years, on the 17 recognized critical components of RCR training and research skill development. We also found about half of the faculty members believe RCR is an institutional responsibility versus a faculty responsibility. Less than a quarter have had opportunities to participate in faculty training to be a better mentor, advisor, or research teacher, and about one third of faculty did not or could not remember whether they had guidelines related to their responsibilities to PhD students. We discuss the implications of our findings and focus on ways that PhD research mentoring can be enhanced. 相似文献

This paper focuses on compost use in overpasses and underpasses for wild animals over roads and other similar linear structures. In this context, good quality of compost may result in faster and more resistant vegetation cover during the year. Inter alia, this can be interpreted also as reduction of damage and saving lives. There are millions of tones of plant residue produced every day worldwide. These represent prospective business for manufacturers of compost additives called “accelerators”. The opinions of the sale representatives’ with regards to other alternatives of biowaste utilization and their own products were reviewed. The robust analyzes of several “accelerated” composts revealed that the quality was generally low. Only two accelerated composts were somewhat similar in quality to the blank sample that was produced according to the traditional procedure. Overlaps between the interests of decision makers on future soil fertility were weighed against the preferences on short-term profit. Possible causes that allowed the boom of these underperforming products and the possible consequences are also discussed. Conclusions regarding the ethical concerns on how to run businesses with products whose profitability depends on weaknesses in the legal system and customer unawareness are to follow. 相似文献

The relationships between race/ethnicity and hypertension or blood pressure (BP), as well as frequency of religious services attendance and hypertension/BP are well documented. However, the association between these three factors is poorly understood. Using national data, this interrelationship was assessed in non-Hispanic whites and blacks, and Mexican-Americans (n = 12,488). Compared to those who never attended services, whites who attended services weekly had lower odds of hypertension, as did blacks who attended more than weekly. There was no relationship between attendance and hypertension among Mexican-Americans. Attendance was inversely related to systolic BP for all groups, but more so for whites and blacks compared to Mexican-Americans. These results further demonstrate the benefits of increased attendance at religious services on hypertension/BP, but suggest that these benefits were not as advantageous for all. 相似文献

ObjectivesTo examine the domain-specific nature of perfectionism in sport and school, and to examine potential links between domain-specific perceived competence, perceived importance (task value), and perfectionism in sport and school.Design and MethodA total of 255 male and female varsity student-athletes from a successful intercollegiate sport program completed domain-specific (i.e., sport and school) versions of Hewitt and Flett's (1991) Multidimensional Perfectionism Scale (HF-MPS). Participants also completed an inventory designed to assess perceived competence (PC) in sport versus school and perceived importance (PI) of success in sport versus school.ResultsExploratory factor analyses conducted on perfectionism data indicated that perfectionist orientations were organized around domain-specific as opposed to global perfectionist tendencies. Regression analyses indicated that PC was a significant predictor of domain-specific levels of self-oriented and socially prescribed perfectionism (ps < .05), and PI was a significant predictor of domain-specific levels of self-oriented, socially prescribed, and other-oriented perfectionism (ps < .001). A repeated-measures MANOVA revealed that student-athletes had significantly higher levels of perfectionism in sport than school (ps < .0001) across all three HF-MPS subscales.ConclusionResults reinforce the value of measuring perfectionism as a domain-specific (rather than global) personality disposition, and identify the potential role that perceived competence and perceived importance may play in the development of domain-specific perfectionism. 相似文献

In the context of the lack of nosological clarity surrounding muscle dysmorphia, this paper aims to compare the symptomatic profile of muscle dysmorphia and anorexia nervosa in males whilst using measures sensitive to indexing male body image concerns. Twenty-one male muscle dysmorphia patients, 24 male anorexia nervosa patients, and 15 male gym-using controls completed the Eating Disorder Examination-Questionnaire, the Muscle Dysmorphia Disorder Inventory, the Compulsive Exercise Test, and a measure of appearance-enhancing substance use. Men with muscle dysmorphia and anorexia nervosa demonstrated widespread symptomatic similarities spanning the domains of disturbed body image, disordered eating, and exercise behaviour, whilst differences were consistent with the opposing physiques pursued in each condition. Furthermore, correlational analyses revealed significant associations between scores on muscle dysmorphia and eating disorder measures. The present findings provide moderate support for the notion that muscle dysmorphia may be nosologically similar to anorexia nervosa. 相似文献

Montesquieu's Considérations sur les causes de la grandeur des Romains et de leur décadence (1733/1734) is a methodological exercise in causal explanation on the meso-level applied to the subject of the military rise and fall of Rome. Rome is described as a system with contingent initial conditions that have a strong path-determining effect. Contingent and plastic initial configurations become highly determining in their subsequent operation, thanks to self-reinforcing feedback loops. Montesquieu's method seems influenced by the ruthless commitment to efficient causality and the reductionism of seventeenth-century mechanicist philosophy; but in contrast to these predecessors, he is more interested in dynamic processes than in unchangeable substances, and his use of efficient causality in the context of a system approach implies a form of holism that is lacking in his predecessors. The formal and conceptual analysis in this article is in many ways complementary with Paul Rahe's recent predominantly political analysis of the Considérations. At the same time, this article points to a problem in the works on the Enlightenment by Jonathan Israel: his account stresses a one-dimensional continuum consisting of Radical, Moderate and Counter-Enlightenment. This invites Israel to place the combined religious, political and philosophical views of each thinker on one of these three points. His scheme runs into trouble when a thinker with moderate religious and political views produces radical philosophical concepts. Montesquieu's Considérations is a case in point. 相似文献

Literature on women’s reproductive health experiences after spinal cord injuries (SCI) documents a temporary period of amenorrhea after women’s injuries. However, research is lacking on how women with SCI feel about amenorrhea or menstruation. That is, we do not know the meanings that women with permanent, physical disability ascribe to their experiences of simultaneously “normal” and “abnormal” reproductive processes. Prioritizing a feminist disability perspective and using interview data from a snowball sample of 20 women with SCI in Detroit, Michigan, in the United States, we outline how interviewees are ambivalent (yet also slightly negative) towards menstruation and amenorrhea within the context of their disability, and may be both different from and similar to able-bodied women in their attitudes and experiences as a result. 相似文献
