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.     

Relational Scaffolding of School Motivation: Developmental Continuities in Students' and Parents' Ratings of the Importance of School Goals

The authors investigated whether parents and students are consistent, over grade levels, in the importance they assign to school goals. Elementary and high school students (n = 178) and their parents (n = 130) completed a questionnaire addressing the personal importance of students' school goals, defined in terms of school success. Parent-child consistencies in the rating patterns of school goals over grade levels were more common than were inconsistencies. These developmental consistencies support the position that students' school goals are embedded within the parent-child relationship (J. Youniss, 1980; J. Youniss & J. Smollar, 1985) and are scaffolded within it (J. S. Bruner, 1975; L. S. Vygotsky, 1978). Potential sources of relational and phenotypic influences on school goals are discussed, as is the need for effective friendship management and school performance in high school.     

An individual's work values in career development

This study examined the mediation effect of career decision self‐efficacy in relation to work values and career decision status. The authors surveyed 308 college students about their own intrinsic (e.g., helping others) and extrinsic (e.g., high income) work values and those of significant others, career decision self‐efficacy, and career decision status. The results indicated that the intrinsic and extrinsic work values of significant others were related to the intrinsic and extrinsic work values of the self and that intrinsic work values were more adaptive than extrinsic work values in career development.     

气质与父母养育对儿童社会适应的交互作用:代表性理论及其证据

最佳适配理论、素质-压力模型、差别易感模型从不同视角阐述了气质、养育方式在儿童社会适应行为中的交互作用机制。最佳适配理论强调气质特质与父母养育方式的良好匹配能促进儿童的社会适应,而不良匹配则会带来适应问题。素质-压力模型强调在不利父母养育条件下,具有"风险"气质特质的儿童更容易出现适应不良,而对"弹性"气质的儿童影响不大。差别易感模型则认为儿童"易感"的气质特质在良好的抚养条件下表现得"更好",而在不利的抚养环境中表现得"更差"。围绕三种代表性理论及其实证研究结果,对当前最新研究结果进行了分析和总结,进一步细分了儿童社会化过程中的风险因素和保护性因素。从气质与积极养育方式的交互作用、养育过程中父母角色分工的差异,以及气质与养育方式动态作用机制三个方面指出了将来进一步探索的方向。     

Exploring the Role of Self-Confidence,Need-for-Cognition,and the Degree of IT Support on Individual Creativity: Multilevel Analysis Approach

In today’s creative economy, individuals generally have not been regarded as reservoirs of creativity who yield sustainable growth in hypercompetitive markets. Individuals rely on IT support to reduce clerical loads and enhance the effectiveness and efficiency of their work as well. When they work in teams, they also require self-confidence and the need for cognition to promote their individual creativity. Data were derived from the members of a large system integration company in South Korea (N = 256, 50 teams). As the study considered variables at both the team and individual levels, we adopted a multilevel analysis approach. We found that individual self-confidence, which indicates the degree of perceived possibility of success at a task, and the need for cognition, the intrinsic motivation to engage in and enjoy thinking, affected individual creativity significantly. Further, the degree of IT support, the team-level variable, had a significant effect on individual creativity. The degree of IT support did not have a significant effect on the relationship between self-confidence and individual creativity, but did have a moderating effect that weakened the relationship between the need for cognition and individual creativity. These findings have implications for theories of members’ creativity in organizations.     

How Do Happy Leaders Enhance Team Success? The Mediating Roles of Transformational Leadership,Group Affective Tone,and Team Processes1

Extending previous research regarding the relationship between leader positive moods and team performance, the present study examined 2 mediating mechanisms that explain the leader positive moods–team performance linkage: transformational leadership, and positive group affective tone. Data were collected from 85 sales teams (85 team leaders, 365 team members). Structural equation modeling analyses were performed to test the hypotheses. The results showed that leader positive moods not only directly enhanced team performance, but also indirectly led to improved team performance through the explicit mediating process (i.e., transformational leadership) and the implicit mediating process (i.e., positive group affective tone). Theoretical and practical implications are discussed.     

the role of career stress in the relationship between maladaptive perfectionism and career attitude maturity in south korean undergraduates

Given the central role of career stress in college students' lives, this research examined whether career stress mediated the relationship between maladaptive perfectionism and career attitude maturity in a sample of 185 undergraduate students in South Korea. The results indicated that career ambiguity stress, as measured by a career stress inventory, fully mediated the relationship between maladaptive perfectionism and career attitude maturity. That is, maladaptive perfectionism correlated with greater levels of career ambiguity stress, and greater career ambiguity stress correlated with an unconstructive level of career attitude maturity. The authors discuss the findings' implications for career counselors in college settings.     

Perceiving expatriate coworkers as foreigners encourages aid: social categorization and procedural justice together improve intergroup cooperation and dual identity

We propose that social categorization can encourage particular forms of intergroup cooperation because it differentiates a group in need from a group that can give aid. Moreover, social categorization is most likely to occur when individuals perceive procedural justice (i.e., fair treatment) from authorities in a superordinate group that includes the individuals' subgroup. Two field studies investigating relations between local and foreign coworkers tested not only this prediction, but also whether high social categorization and procedural justice would yield a dual identity, in which group members identify simultaneously with their social category and the superordinate group. Both studies supported our predictions: Local employees engaged a dual identity and offered knowledge to aid a foreign coworker's adjustment more often when local-foreign categorization and procedural justice from organizational authorities were high than when these variables were low. These discoveries point to controllable mechanisms that enable intergroup cooperation, and our findings have important implications for intergroup aid, expatriate adjustment, immigration, and multiculturalism.     

正负性情绪的自主神经反应及应用

情绪可以唤醒自主神经系统, 伴随有一系列的生理变化。从基础研究的角度来看, 正负性情绪可以诱发心血管系统(如心率、血压、心率变异性)、皮肤电系统(如皮肤电导水平)、呼吸系统(如呼吸阻力、每分通气量)和其他系统(如瞳孔直径、胃肌电等)的活动及其变化。在应用研究方面, 正负性情绪诱发的自主神经反应可以应用在多个领域, 主要包括用户体验中的情绪测量、基于生理信号的人-机情感交互系统的开发, 以及消费者态度和偏好的测查等。对于现有研究结果中存在的分歧, 从被试的个体差异、诱导范式的不一致性和诱导效果的可靠性, 以及刺激材料属性的多样化等方面进行了分析, 指出了未来研究应该注意的问题。
