Co-occurrence of substance use disorders (SUDs) and posttraumatic stress disorder (PTSD) is extremely common and is associated with elevated dropout and relapse rates. Given that PTSD/SUD co-occurrence rates among veterans have been found to be as high as 55?75%, it is important to identify mechanisms that may affect the interplay of both disorders. Emotion dysregulation (ED) presents a candidate mechanism that may underlie poor treatment response in co-occurring PTSD/SUD. This article proposes a transdiagnostic emotion regulation framework that considers ED conceptualized as a combination of low ability to tolerate emotional distress (low distress tolerance) and difficulties in the goal-directed use of emotion regulation strategies as a key risk factor in co-occurring PTSD/SUD. The authors review empirical findings from self-report and laboratory-based studies of ED in PTSD. They describe psychological explanations of the emotion-substance relationship and review studies documenting ED in SUDs and in co-occurring PTSD/SUD. The literature on ED in PTSD/SUD suggests that (a) patients with PTSD may resort to substances to cope with trauma-related symptoms due to ED, and (b) ED may maintain SUD symptoms and interfere with psychological treatment. Longitudinal studies on bidirectional relationships between ED and substance use in PTSD are needed, particularly research examining the course of ED in PTSD patients who use substances versus those who do not. 相似文献

This essay concerns the question of how we make genuine epistemic progress through conceptual analysis. Our way into this issue will be through consideration of the paradox of analysis. The paradox challenges us to explain how a given statement can make a substantive contribution to our knowledge, even while it purports merely to make explicit what one’s grasp of the concept under scrutiny consists in. The paradox is often treated primarily as a semantic puzzle. However, in “Sect. 1” I argue that the paradox raises a more fundamental epistemic problem, and in “Sects.1 and 2” I argue that semantic proposals—even ones designed to capture the Fregean link between meaning and epistemic significance—fail to resolve that problem. Seeing our way towards a real solution to the paradox requires more than semantics; we also need to understand how the process of analysis can yield justification for accepting a candidate conceptual analysis. I present an account of this process, and explain how it resolves the paradox, in “Sect. 3”. I conclude in “Sect. 4” by considering the implications for the present account concerning the goal of conceptual analysis, and by arguing that the apparent scarcity of short and finite illuminating analyses in philosophically interesting cases provides no grounds for pessimism concerning the possibility of philosophical progress through conceptual analysis. 相似文献

This article is a study of the Later Mohists' ‘Lesser Selection (Xiǎoq )’, which, more than any other early Chinese text, seems to engage in the study of logic. I focus on a procedure that the Mohists called móu . Arguments by móu are grounded in linguistic parallelism, implying perhaps that the Mohists were on the way to a formal analysis of argumentation. However, their main aim was to head off arguments by móu that targeted their own doctrines, and if their argument succeeds then it entails that linguistic parallelism can never ground a cogent argument. In a way, this committed them to the view that formal logic cannot work, but the fact that they did not pursue this line of investigation was by no means inevitable. One consequence of this study is that the Later Mohists conducted their logical work by studying the behaviour of terms and verb phrases, and did not identify the sentence as a significant linguistic unit. This tends to confirm Chad Hansen's generalisation that early Chinese philosophers did not posit sentences or other sentence-like entities such as propositions, beliefs, or laws. Focusing on subsentential expressions did not stop the Mohists from addressing genuinely logical issues, but it may help explain the fact that they never developed a conception of logical structure. This study includes the complete Chinese text of the ‘Lesser Selection’ and a translation in English. 相似文献

This discussion piece reflects on menstrual cycle research since the founding of the Society for Menstrual Cycle Research in the context of contemporary research presented in this special issue of Sex Roles. Although women researchers in the 19th century began documenting that normal menstruation is neither disabling nor dangerous, taboos, concealment and avoidance of menstruation persist. Feminist researchers have worked to find ways to support women’s health and wellbeing within a sociocultural milieu still reflecting largely negative views of menstrual cycle phenomena. The present collection of current menstrual cycle research offers useful contextual approaches to understanding why menstruation remains in the shadows, and how to resist negative characterizations, as well as encourage curiosity and body awareness. Alternatives to mainstream corporate and medical views of menstrual phenomena are discussed. Fruitful theoretical and methodological directions for research are identified to support advocacy, educational, and therapeutic interventions for menstrual health. 相似文献

Evaluating salespeoples' performance is an important task for sales managers. However, little is known about what bases are used by sales managers to evaluate the performance of their salespeople. A study was conducted to determine the bases actually used by sales managers and the results were compared with a study conducted in 1983. Findings indicate more emphasis on profit and cost control, a continued reliance on qualitative measures, and a wide variety of bases being utilized to evaluate the performance of salespeople. Furthermore, the stability of results, across a wide variety of respondent job titles as well as business types and sizes, indicates a good deal of generalizability to other firms. 相似文献

Corporate recruiting on college campuses has been an important vehicle for selecting and hiring new employees. Previous research has focused on identifying, locating, and selecting new employees, but the recruiting function of attracting good prospects to the interview and job has received less research attention. Increased importance of the attraction function of recruiting may be indicated for the future, particularly given projections of a decline in business college enrollments. The purpose of this article is to examine recruitment of college graduates for sales positions, using the perspective of attracting employees by communicating aspects of the job and company which are important to them. A survey of students and recruiters was used to reveal the attributes of importance to students, differences among students, and the extent to which recruiters are aware of student importance ratings. Differences between students and recruiters perceptions are identified for half of the 50 attributes examined, revealing an opportunity for recruiters to obtain better knowledge of students' perceptions and, thus, to improve their ability to attract graduates to sales positions. 相似文献

Objective: This study tested whether social cognitions from the reasoned action approach (RAA) can be reliably measured in a sample of primary school children (aged 4–6 years) and whether these RAA measures are predictive of physical activity.Design: Longitudinal observational study with repeated measures over six months.Measures: RAA variables were measured using a novel choice paradigm between physically active and sedentary pastimes. Relative reinforcing value, covariates (sex, age, deprivation and BMI) and physical activity by accelerometry (primary outcome) were also measured.Results: RAA cognitions could be measured with acceptable retest reliability and discriminant validity and social norms regarding parents and teachers (but not friends) were correlated with physical activity and change in physical activity when relative reinforcing value and other covariates were controlled for.Conclusions: RAA cognitions can be reliably measured in primary school children aged 4–6 and RRA measures appear useful in understanding children’s activity choices and may potentially inform future interventions. 相似文献

Abstract The fear of dental treatment in adults can be characterised in several ways, loosely related, such as anticipating being afraid, avoiding dental check-ups and seeking treatment only under general anaesthesia. Defined thus, at least a quarter of adults are highly afraid of dentistry. The feared experiences are many, including most frequently, pain. Several studies have shown that anxious patients experience less pain during treatment than they expect. It remains to be confirmed that these are typical experiences because other studies show that local anaesthesia can fail to protect patients from sudden pain in 13% of treatments on average. Expectations of pain are highly resistant to change, the result probably of several influences including distortion in recall of pain-free treatment, intermittent experience of sudden severe pain, expecting pain in order to reduce its impact, and uncertainty about treatment. It has yet to be shown that experience free of discomfort can reduce these expectations. However, relaxation instructions and information about pain management and stop signals can reduce pre-treatment fear. To prevent the onset and the maintenance of anxiety: the prevention of pain is essential; controlled behavioural studies of the treatment of pain and other experiences such as panics are needed. Finally, the need for new instruments to assess all aspects of fear of dentistry is described. 相似文献
