Correlates of Adolescent Cyberbullying in South Korea in Multiple Contexts: A Review of the Literature and Implications for Research and School Practice

Cyberbullying is rapidly increasing in South Korea. The present article reviews research on factors associated with cyberbullying perpetration and victimization in South Korea. Study findings suggest a number of factors within individual, family, peer, and school levels. Relations with parents, parental verbal abuse, and a lack of attachment are related to perpetration. Delinquent peer association is positively associated with perpetration and victimization, and students’ school satisfaction is negatively associated with this victimization. Adolescents’ use of social networking sites and social media and lack of rules in cyberspace are found to increase perpetration and victimization. Research and practice implications are discussed.     

ICU护士角色模糊-角色冲突和工作疲溃感对其组织承诺的影响

了解ICU护士的角色模糊-角色冲突、工作疲渍感和组织承诺水平,探讨角色模糊-角色冲突和工作疲溃感对ICU护士组织承诺的影响作用.角色模糊对ICU护士的组织承诺有显著的预测作用(P＜0.01).在情感承诺方面,角色模糊和情绪疲溃感有显著的负向预测作用(P＜0.01);情绪疲溃感和个人工作无成就感对继续承诺有显著的影响(P＜0.05);情绪疲溃感、角色冲突和角色模糊对规范承诺有显著的负向预测作用(P＜0.05).护理管理者应采取积极有效的措施减轻其影响,稳定护理队伍,提高护理质量.     

小学生同伴接纳对其人格发展的影响：友谊质量的多层级中介效应

以班级为单位选取1-6年级23个班级的小学生,通过最好朋友提名法,得到有互选朋友有效被试700人,采用同伴提名法、小学生友谊质量问卷、小学生人格发展教师评定问卷,运用多层线性模型（HLM）考察个体和班级两个水平上的同伴接纳、友谊质量对人格的影响,并在两个水平上检验友谊质量在同伴接纳对人格的影响上的多层中介效应。结果表明：（1）班级水平：班级平均友谊质量对外倾性、亲社会性、认真自控、情绪稳定性有预测作用;班级平均同伴接纳对情绪稳定性有预测作用。（2）个体水平：同伴接纳对人格5个维度均有直接影响;除情绪稳定性,友谊质量分别在同伴接纳对智能特征、外倾性、亲社会性、认真自控影响上有部分中介效应。     

Resilience: A Meta‐Analytic Approach

This study investigated the relationship between psychological resilience and its relevant variables by using a meta‐analytic method. The results indicated that the largest effect on resilience was found to stem from the protective factors, a medium effect from risk factors, and the smallest effect from demographic factors.     

Dysfunctional Behavior among Sales Representatives: The Effect of Supervisory Trust,Participation, and Information Controls

This study investigates the efficacy of supervisory trust, participation, and information controls in curbing dysfunctional salesperson behavior so that salesperson actions are in line with organizational goals. Using a sample of 210 salespeople, we develop and test a model incorporating supervisory trust, participation, information controls (output information, activity information, and capability information), and dysfunctional behavior. Output and activity information controls directly affect dysfunctional behavior, whereas capability information controls work positively through trust in the supervisor to reduce dysfunctional behavior. Providing sales representatives with information about their capabilities appears to enhance the supervisor–salesperson trust relationship. Results also indicate that salespeople’s supervisory participation is an effective lever for reducing dysfunctional salesperson behavior through the intervening role of trust in the supervisor.     

Re-precipitation of coherent γ-Fe particles following annealing of equal-channel angular pressed Cu–Fe alloy

The transformation of second-phase particles in a Cu–Fe alloy following equal-channel angular extrusion and annealing has been determined by transmission electron microscopy. Equal-channel angular pressing of the Cu–Fe alloy transformed coherent γ-Fe particles in the Cu matrix into incoherent α-Fe. Upon annealing, numerous coherent γ-Fe particles were observed. A dislocation–particle interaction mechanism is suggested to explain the re-precipitation of coherent γ-Fe particles following annealing.     

The usefulness of the story recall test in patients with mild cognitive impairment and Alzheimer's disease

ABSTRACT

Background: The story recall test (SRT) is one of the most reliable neuropsychological assessments for evaluating verbal memory function in order to distinguish between individuals with normal aging, mild cognitive impairment (MCI), and Alzheimer's disease (AD). The SRT is analogous to the logical memory test in Wechsler Memory Scale-III, which has recently been developed and standardized to apply to older adults in Korea. The purpose of this study was to examine the usefulness of the SRT and its ability to discriminate between normal cognitive aging and patients with MCI or AD. Methods: One hundred and twelve patients with MCI, 97 patients with AD, and 53 healthy elderly adults participated in this study. The SRT was compared with the Clinical Dementia Rating (CDR), Global Deterioration Scale (GDS), Korean version of the Mini Mental State Examination (K-MMSE), and the Korean version of the Hopkins Verbal Learning Test (K-HVLT). Results: The SRT was well-correlated with the dementia rating scales and the K-HVLT. However, the sensitivity and specificity of the SRT was greatly influenced by the level of education of the subjects. Conclusions: The SRT is a sensitive measurement of verbal memory function that can be used in clinical settings to discriminate between normal memory functioning and the very early and moderate stages of AD in a Korean population. Moreover, it is important to recognize that the SRT is more appropriate for subjects with a high level of education rather than a low level of education to differentiate normal cognitive aging from MCI or AD.     

恶性肿瘤的过度治疗及其防范

恶性肿瘤的过度治疗涉及到手术、放疗、化疗、靶向治疗、生物治疗等多个方面,严重影响了患者的生存质量。造成这一现象的原因是多方面的：患者由于对肿瘤的恐惧而形成过分关注;医生未及时更新治疗观念,过于注重对肿瘤的彻底杀伤,并对自己行医的过分保护;医院的不恰当管理。为了促进肿瘤治疗环境的合理化,我们应该防范过度治疗,加强宣传教育,完善医德医风,促进医疗改革的顺利完成。倡导合理、受益性治疗,使患者达到长期带瘤生存的目的。     

Individual problem‐solving styles and attitudes toward divergent thinking before and after training

ABSTRACT:

Afield experiment was conducted to examine the mediating effect of individual creative problem‐solving style on the impact of training in creative thinking. This intensive hands‐on training emphasized a specific three‐phase process which synchronizes divergence and convergence in problem‐finding, problem‐solving, and implementation. Two attitudes associated with divergent thinking were measured before and after training. The sample was comprised of a mixture of organizational members representing both managers (n = 90) and non‐managers (n = 66) and a variety of functional specialties, hierarchical levels, and types of business organizations. The most significant finding was that the optimizer style of creative problem‐solving improved more than the other three styles (generator, conceptualizer, and implementor) on measures of both creative thinking attitudes.
