Both researchers and practitioners need to know more about how laboratory treatment protocols translate to real-world practice settings and how clinical innovations can be systematically tested and communicated to a skeptical scientific community. The single-case time-series study is well suited to opening a productive discourse between practice and laboratory. The appeal of case-based time-series studies, with multiple observations both before and after treatment, is that they enrich our design palette by providing the discipline another way to expand its empirical reach to practice settings and its subject matter to the contingencies of individual change. This article is a user's guide to conducting empirically respectable case-based time-series studies in a clinical practice or laboratory setting. 相似文献
A questionnaire about how academic performance is evaluated and the importance of teaching and research was completed by 265 faculty at a UK research university. Factor analysis followed by t-tests showed that male faculty had a more realistic understanding of how their research is evaluated, rate the importance of research to their careers more highly, and are more likely than women to work over hours through choice. Women faculty are more likely than men to work over hours because of teaching workload and rate the importance of a teaching qualification more highly, despite giving similar ratings as men to the importance of teaching to their career. The implications for differential rates of promotion are discussed. 相似文献
This study used latent transition analysis (LTA) to examine changes in early emotional and behavioral problems in children
age 2 to 4 years resulting from participation in a family-centered intervention. A sample of 731 economically disadvantaged
families was recruited from among participants in a national food supplement and nutrition program. Families with toddlers
between age 2 and 3 were randomized either to the Family Check-Up (FCU) or to a nonintervention control group. The FCU’s linked
interventions were tailored to each family’s needs. Assessments occurred at age 2, 3, and 4. The FCU followed age 2 and age
3 assessments. Latent class analyses were conducted on mother reports of behavior and emotional problems from age 2 to 4 to
study transitions among the following four groups: (a) externalizing only, (b) internalizing only, (c) comorbid internalizing
and externalizing, and (d) normative. LTA results revealed that participation in the FCU increased the likelihood of transitioning
from either the comorbid or the internalizing class into the normative class by age 4. These results suggest family interventions
in early childhood can potentially disrupt the early emergence of both emotional and behavioral problems. 相似文献
Late in their paper on hypersets, Chemero and Turvey characterize affordances as “quicksilvery,” prone to rapid appearance and disappearance. We contrast this view with Gibson’s emphasis on the stability of affordances. We argue that this apparent discrepancy can be resolved by appeal to the distinction between affordances as indefinite abstract types and definite affordance tokens (instances of the type that share the resemblance relation). These issues will be discussed in the context of their consistency with ecological realism, where Platonic idealism is eschewed in favor of a more Aristotelian process theory. These ideas will be examined in the broader context of the domain ontology to ensure that Gibson's seminal affordance concept has its greatest theoretical utility. Finally, we develop a process theory of ontological descent by which indefinite affordance possibilities become more definite affordance potentialities and these eventuate in the most definite affordance actualizing actions. 相似文献
Genetic counselors frequently counsel clients whose first language is not English, relying on interpreters and on supplementary translated written material. This paper highlights factors that counselors need to consider before using or commissioning translated leaflets. It is based on an assessment of leaflets translated into Urdu, the national language of Pakistan, which are available through U.K. genetics clinics for use with Pakistani-origin clients. The 2 authors, who know Urdu as their 2nd and 1st languages respectively, independently read each leaflet, checking for accuracy of information, ease of reading and understanding, cultural sensitivity, and contact details for Urdu-speaking professionals. There were factual errors and confusing or very difficult text in all leaflets; some leaflets also contained culturally insensitive messages that could alienate users of genetics services. The paper discusses the reasons for these pitfalls and makes recommendations to guide the future production of translated genetics leaflets. 相似文献
The present study was designed to explore the effects of warned and unwarned demand transitions in vigilance on performance and self-reported stress. Twenty observers (10 women and 10 men) were assigned at random to each of six conditions resulting from the factorial combination of signal salience (high and low salience signals) and switching (no switch, switch with warning, and switch without warning). Performance metrics and self-reported stress state (Task Engagement, Distress, and Worry) were collected. While demand transitions did destabilize subsequent performance, increasing intra-individual variability, overall performance efficiency was uninfluenced by either switching or warning. Demand transitions, whether warned or not, increased self-reported distress. A dynamic model of performance stress may be necessary and research employing vigilance tasks in the future may be useful for developing this performance-stress model. 相似文献
The present study examined prevalence of lack of a close confidant in a medically underserved primary care sample, and evaluated demographic, medical, and psychological correlates of patients' deficits in close, personal contact. Adult patients (n = 413) reported on confidant status and symptoms of depression and anxiety. Sociodemographic and medical information were obtained through chart review. One-quarter of patients endorsed lack of a close confidant. Past month anxiety and depression symptoms, but not medical status, were associated with unmet socioemotional needs. Implications for primary healthcare interventions are discussed. 相似文献
The present study estimated the unique contribution of self-efficacy to work-related performance controlling for personality (the Big 5 traits), intelligence or general mental ability, and job or task experience. Results, based on a meta-analysis of the relevant literatures, revealed that overall, across all studies and moderator conditions, the contribution of self-efficacy relative to purportedly more distal variables is relatively small. Within moderator categories, there were several cases in which self-efficacy made unique contributions to work-related performance. For example, self-efficacy predicted performance in jobs or tasks of low complexity but not those of medium or high complexity, and self-efficacy predicted performance for task but not job performance. Overall, results suggest that the predictive validity of self-efficacy is attenuated in the presence of individual differences, though this attenuation does depend on the context. 相似文献
To anyone vaguely aware of Feyerabend, the title of this paper would appear as an oxymoron. For Feyerabend, it is often thought, science is an anarchic practice with no discernible structure. Against this trend, I elaborate the groundwork that Feyerabend has provided for the beginnings of an approach to organizing scientific research. Specifically, I argue that Feyerabend’s pluralism, once suitably modified, provides a plausible account of how to organize science. These modifications come from C.S. Peirce’s account of the economics of theory pursuit, which has since been corroborated by empirical findings in the social sciences. I go on to contrast this approach with the conception of a ‘well-ordered science’ as outlined by Kitcher (Science, truth, and democracy, Oxford University Press, New York, 2001), Cartwright (Philos Sci 73(5):981–990, 2006), which rests on the assumption that we can predict the content of future research. I show how Feyerabend has already given us reasons to think that this model is much more limited than it is usually understood. I conclude by showing how models of resource allocation, specifically those of Kitcher (J Philos 87:5–22, 1990), Strevens (J Philos 100(2):55–79, 2003) and Weisberg and Muldoon (Philos Sci 76(2):225–252, 2009), unwittingly make use of this problematic assumption. I conclude by outlining a proposed model of resource allocation where funding is determined by lottery and briefly examining the extent to which it is compatible with the position defended in this paper.
