The effects of childhood abuse on symptom complexity in a clinical sample: Mediating effects of emotion regulation difficulties     

Ji Young Choi  Young Min Choi  Min Sook Gim  Jun Hyun Park  Soo Hyun Park 《Child abuse & neglect》2014

The purpose of the present study was to first examine whether childhood abuse predicts symptom complexity, as indicated by the number of clinically elevated scales on the MMPI-2 in an adult clinical sample. Secondly, we investigated whether emotion regulation difficulties mediated the relationship between childhood abuse and symptom complexity. A total of 162 adult outpatients not presenting with psychotic symptoms completed the Korean Childhood Trauma Questionnaire (K-CTQ), Life Events Checklist (LEC), Difficulties in Emotion Regulation Scale (DERS), and Korean Minnesota Multiphasic Personality Inventory-2 (MMPI-2). Partial correlation analysis results indicated that after controlling for the presence of adulthood trauma, childhood abuse was associated with more symptom complexity, or more clinically elevated scales on the MMPI-2. Furthermore, structural equation modeling results showed that emotion regulation difficulties partially mediated the relationship between childhood abuse and symptom complexity. These findings indicate that individuals who had experienced childhood abuse evidence simultaneous presentation of diverse clinical symptoms.  相似文献   

The road to self-assessment: exemplar marking before peer review develops first-year students’ capacity to judge the quality of a scientific report     

Robyn Yucel  Fiona L. Bird  Jodie Young  Tania Blanksby 《Assessment & Evaluation in Higher Education》2014,39(8):971-986

Lack of clarity about assessment criteria and standards is a source of anxiety for many first-year university students. The Developing Understanding of Assessment for Learning (DUAL) programme was designed as a staged approach to gradually familiarise students with expectations, and to provide opportunities for the development of the skills required to successfully complete assessment tasks. This paper investigated the students’ perceptions of the first two components of the DUAL programme, which assist first-year biology students to engage with stated assessment criteria and standards in order to develop their capacity to make judgements about scientific report exemplars, their peers’ scientific reports and ultimately their own. The study found strong evidence (96% of responses) that the marking and discussion of exemplar reports with peers and demonstrators clarified expectations of scientific report writing. A key feature of this element of DUAL was the opportunity for structured discussion about assessment criteria and standards between peers and markers (demonstrators). During these discussions, students can clarify explicit statements and develop a tacit knowledge base to enhance their ability to judge the quality of others’ work and their own. The peer review exercise (the second element of DUAL) was not rated as highly, with 65% of students finding the process helpful for improving their report. The negative reactions by a sizeable minority of students highlight the need to clearly communicate the expectations and benefits of peer review, with a focus on how the process of giving feedback to peers might benefit a student as much as receiving feedback on their own report.  相似文献   

The Affect Effect of Political Satire: Sarcastic Humor,Negative Emotions,and Political Participation     

Hoon Lee  Nojin Kwak 《Mass Communication and Society》2014,17(3):307-328

Building on the Orientation-Stimulus-Orientation-Response (O-S-O-R) framework, the current study proposes a mediation model wherein negative emotions serve as a second O. An online experiment using a representative sample demonstrated that consuming sarcastic political humor can indirectly increase the likelihood of political participation by eliciting negative emotions toward a government policy. In addition, we introduced education as a first O, illustrating that the indirect mobilizing effect of the viewing of sarcastic humor through negative emotions is stronger for political sophisticates. The proposed model suggests avenues for exploring the role of emerging media genres that are presumably less enlightening yet are more emotionally provocative.  相似文献   

Humor Works in Funny Ways: Examining Satirical Tone as a Key Determinant in Political Humor Message Processing     

Heather L. LaMarre  Kristen D. Landreville  Dannagal Young  Nathan Gilkerson 《Mass Communication and Society》2014,17(3):400-423

This multi-experiment study builds upon extant political entertainment theory, testing whether satire type (horatian versus juvenalian) cues varying processing mechanisms (message discounting versus resource allocation), and if consequential differences to argument scrutiny levels or message persuasiveness result. Using novel stimuli (e.g., animated cartoons, study one) and real-world late-night political satire (The Daily Show and The Colbert Report, study two), results suggest that satire type was a key antecedent in political humor message processing. Additionally, the varying mechanisms had differential effects on political argument scrutiny levels and message persuasiveness.  相似文献   

The formation of concern for face and its impact on knowledge sharing intention in knowledge management systems     

Mei-Lien Young 《知识管理研究与实践》2014,12(1):36-47

Previous empirical studies have shown that in Chinese culture face is critical for the success of knowledge sharing in knowledge management systems (KMS). However, much less is known about the factors shaping the concern for face and the way they impact on the individual's knowledge sharing intention in KMS. Using data drawn from professionals’ knowledge sharing practices in Taiwanese organizations, this study focuses on a detailed investigation of the concern for face and how it impedes individuals’ knowledge sharing intention in the KMS context. The research findings show that the perfection of authentic self and the scrutiny of others (referred to as others’ watch) together explain 27.7% of the variance in face in relation to public self. In turn, face related to public self explains 20.7% of subjective norms. Finally, face related to public self and subjective norms together account for 41.2% of the variance in knowledge sharing intention. The research findings have important theoretical and managerial implications.  相似文献

Effects of light refraction on the accuracy of camera calibration and reconstruction in underwater motion analysis     

Young‐Hoo Kwon  Jeffrey B. Casebolt 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(2):315-340

One of the most serious obstacles to accurate quantification of the underwater motion of a swimmer's body is image deformation caused by refraction. Refraction occurs at the water‐air interface plane (glass) owing to the density difference. Camera calibration‐reconstruction algorithms commonly used in aquatic research do not have the capability to correct this refraction‐induced nonlinear image deformation and produce large reconstruction errors. The aim of this paper is to provide a thorough review of: the nature of the refraction‐induced image deformation and its behaviour in underwater object‐space plane reconstruction; the intrinsic shortcomings of the Direct Linear Transformation (DLT) method in underwater motion analysis; experimental conditions that interact with refraction; and alternative algorithms and strategies that can be used to improve the calibration‐reconstruction accuracy. Although it is impossible to remove the refraction error completely in conventional camera calibration‐reconstruction methods, it is possible to improve the accuracy to some extent by manipulating experimental conditions or calibration frame characteristics. Alternative algorithms, such as the localized DLT and the double‐plane method are also available for error reduction. The ultimate solution for the refraction problem is to develop underwater camera calibration and reconstruction algorithms that have the capability to correct refraction.  相似文献   

Examining relative age effects on performance achievement and participation rates in Masters athletes     

Nikola Medic  Janet L. Starkes  Bradley W. Young 《Journal of sports sciences》2013,31(12):1377-1384

Abstract

Although the relative age effect has been widely observed in youth sports (Musch & Grondin, 2001 Musch, J. and Grondin, S. 2001. Unequal competition as an impediment to personal development: A review of the relative age effect in sport. Developmental Review, 21: 147–167. [Crossref], [Web of Science ®] , [Google Scholar]), it is unclear whether it generalizes across the lifespan. The purpose of this study was to examine the relative age effect among a population of Masters athletes using archived data. Two successive studies examined the frequency of record-setting achievements (Study 1) and the frequency of participation entries (Study 2) at the US Masters track-and-field and swimming championships as a function of an individual's constituent year within any 5-year age category. Results of Study 1 indicated that the probability of setting a record increased if Masters athletes were in the first year, and decreased if they were in the third, fourth or fifth year, of an age category. Results of Study 2 indicated that the likelihood of participating in the National championships increased if Masters athletes were in the first or second year, and decreased if they were in the fourth or fifth year, of an age category. We highlight and discuss potential advantages afforded to Masters athletes who are relatively younger than their peers in the same 5-year age category.  相似文献   

A qualitative investigation of the temporal patterning of the precompetitive anxiety response     

Sheldon Hanton  Stephen D. Mellalieu  Stuart G. Young 《Journal of sports sciences》2013,31(11):911-928

The aim of this study was to examine retrospective perceptions and causal beliefs about temporal experiences of competitive anxiety and related symptoms in the lead up to competition. Qualitative interviews were conducted with 9 elite performers to examine the interaction of intensity, frequency and direction of symptoms associated with competitive anxiety before competition. Data analysis identified six causal networks that supported theoretical predictions suggesting that intensity of cognitive anxiety symptoms remained relatively stable in the lead up to competition, whereas somatic anxiety peaked sharply at the onset of performance. Frequency of anxiety symptoms increased as the competition approached and changes in interpretation of anxiety symptoms were also reported, with self-confidence identified as a moderating variable. The findings highlight the dynamic properties of the stress response and emphasize the need to consider the idiosyncratic nature of the level, frequency and interpretation of performers' precompetitive experiences.  相似文献   

Gender,age, and sport differences in relative age effects among US Masters swimming and track and field athletes

Abstract

The aim of the present study was to examine elbow joint extension power-load characteristics with and without a countermovement. Eight male participants performed maximal elbow extensions with and without a countermovement against different loads (0, 2.5, 5.0, 7.5, 10.0, 12.5, and 15.0 kg). Electromyographic activity of the lateral and long heads of the triceps brachii and the biceps brachii muscles was recorded. The average joint power in the concentric phase was significantly enhanced in the countermovement condition at all loads except for 0 kg. The optimal load for the maximal joint power was greater in the countermovement (7.5 kg) than in the no countermovement condition (5.0 kg). Electromyographic activity was unchanged over the intensities and conditions. Our results suggest that the optimal load for the maximal joint power depends on the type of action (i.e. with or without a counter-movement), and that the enhanced joint power in the countermovement condition is due primarily to the storage and utilization of elastic energy.  相似文献
