“Historicism” has become a ubiquitous and equivocal term. A classification is given here of five separate uses of the term currently in vogue, each provided with a unique qualifying adjective to help keep them distinct. I then offer a few objections to some of the more radical conclusions which have been drawn by proponents of a specific version of historicism, one associated with “postmodernism “. The positions of Rorty and Putnam are contrasted as examples of strong and weak degrees of historicism, respectively. 相似文献

This research was designed to identify entrepreneurial value orientations by comparing them with the value orientations of professional managers. The SYMLOG values measuring instrument was administered in Thailand to Thai entrepreneurs ( n = 55) and Thai professional managers ( n = 200). Results show that the value orientation of the entrepreneurs differed significantly from that of professional managers on several dimensions, particularly with regard to those elements that almost always contribute to teamwork effectiveness. Implications for training and staffing are discussed. 相似文献

Low‐SES couples have limited resources to manage the chronic and acute stressors with which they are disproportionately faced. Although these couples are at greater risk for negative individual and relationship outcomes, evaluations of the impact of couple relationship education (CRE) in low‐SES couples have been plagued by methodological problems, most notably challenges associated with recruitment and retention. We review the literature on challenges couples face associated with low‐SES, as well as on recruitment, retention, and CRE in low‐SES, ethnic minority populations. We illustrate some of these challenges in a case study of CRE for low‐SES couples transitioning to parenthood. In this pilot study, 21 couples were recruited from a community health clinic and randomized to either an experimental treatment condition (EXP; N = 11) or a treatment‐as‐usual control condition (TAU; N = 10). This study sought to mitigate documented challenges with recruitment and retention: We leveraged community partnerships, attempted to build and maintain strong relationships with study participants, provided incentives for assessments as well as intervention meetings, and attempted to reduce potential barriers to enrollment and retention. Nonetheless, we had low rates of recruitment and retention. We integrate these findings and experiences with our review of previous work in this area. We make recommendations for future CRE research and practice that have potential implications for public policy in this area. 相似文献

In his article ‘Doing, allowing, and the problem of evil’ recently published in this journal, Daniel Lim attempts to undermine the following claims with respect to God: (1) the doing-allowing distinction exists and (2) the doing-allowing distinction is morally significant. I argue that Lim’s attempt is unsuccessful, and that his understanding of divine providence has the unacceptable consequence of implying that God is the originator of evil. 相似文献

This article discusses the following question: what epistemic relation must audiences bear to the content of assertions in order to gain testimonial knowledge? There is a brief discussion of why this issue is of importance, followed by two counterexamples to the most intuitive answer: that in order for an audience to gain testimonial knowledge that p they must know that the speaker has asserted p . It is then suggested that the argument generalises and can be made to work on different sets of assumptions about the conditions for knowledge, and the conditions under which a proposition is asserted. 相似文献

A guiding question for this special section, sparked by the increasing number of studies on callous –unemotional traits (CU traits) and the DSM-5 Limited Prosocial Emotion (LPE) specifier, is whether CU traits are enough to identify a clinically meaningful subgroup of youth with conduct problems or whether other psychopathic traits contribute. Seven empirical papers and two commentary papers address this question to varying degrees and in different ways with some papers “competing” various models against one another along with other papers investigating distinct correlates of the psychopathy factors. Findings across the papers suggest that there could be benefits to examining the broader construct of psychopathy in addition to examining its underpinning dimensions rather than CU traits alone. Two commentary papers also shed light on the importance of psychopathic traits in children with Conduct Disorder (CD) and provide insights for future work on this topic. It is hoped that the articles and commentary will generate new ideas for research and practice that could have implications for the treatment of those individuals with CD and psychopathic traits. 相似文献

Are Words Easier to Learn From Infant‐ Than Adult‐Directed Speech? A Quantitative Corpus‐Based Investigation

We investigate whether infant‐directed speech (IDS) could facilitate word form learning when compared to adult‐directed speech (ADS). To study this, we examine the distribution of word forms at two levels, acoustic and phonological, using a large database of spontaneous speech in Japanese. At the acoustic level we show that, as has been documented before for phonemes, the realizations of words are more variable and less discriminable in IDS than in ADS. At the phonological level, we find an effect in the opposite direction: The IDS lexicon contains more distinctive words (such as onomatopoeias) than the ADS counterpart. Combining the acoustic and phonological metrics together in a global discriminability score reveals that the bigger separation of lexical categories in the phonological space does not compensate for the opposite effect observed at the acoustic level. As a result, IDS word forms are still globally less discriminable than ADS word forms, even though the effect is numerically small. We discuss the implication of these findings for the view that the functional role of IDS is to improve language learnability. 相似文献

Posttraumatic stress disorder (PTSD) and substance use disorder (SUD) commonly co-occur. Emerging research suggests that both distress tolerance and impulsivity may underlie this comorbidity. However, to our knowledge no studies have examined whether these 2 constructs predict outcome in PTSD-SUD treatment. The current study investigated whether pretreatment distress tolerance and impulsivity predicted posttreatment PTSD and cravings severity in a sample of 70 Veterans receiving concurrent treatment for PTSD and SUD in a residential day treatment program. Veterans completed measures of symptom severity before and after treatment. Results demonstrated that pretreatment distress tolerance predicted posttreatment PTSD severity while controlling for pretreatment PTSD. By contrast, pretreatment impulsivity was not predictive of posttreatment PTSD while controlling for pretreatment values. Neither distress tolerance nor impulsivity predicted posttreatment cravings severity. The findings support the notion that distress tolerance may help to explain the co-occurrence of PTSD and SUD and suggest that targeting this construct in PTSD-SUD treatment may be important for successful outcomes. 相似文献

Objective: The authors attempted to develop and validate a general distress index for a multidimensional psychological symptom/outcome measure used in over 300 college counseling centers with more than 100,000 cases annually: the Counseling Center Assessment of Psychological Symptoms (CCAPS). Method: Four models were compared for fit indices (n = 19,247): the existing first-order factor model (without a general factor), a second-order factor model, a bifactor model, and a single factor or “total score” model. In separate clinical and non-clinical samples, concurrent and divergent validity were examined using several well-established measures of psychological symptoms, as well as two-week test–retest and treatment utilization data. Results: Second-order and bifactor models which captured a single “distress” factor both exhibited good fit to the data relative to the baseline and “total score” model. Validity data indicated that factors adequately measured meaningful clinical onstructs. Conclusion: Both the bifactor and second-order models indicated the presence of a “distress index” comprised items across many of the CCAPS subscales. This distress scale has strong applicability for benchmarking the overall severity and complexity of patients at different centers, and can be used to help identify colleges and universities with areas of clinical strength, which can be studied to improve the field. Clinically, the distress index offers a parsimonious and efficient method for clinicians to monitor patients’ progress through treatment. 相似文献
