Associations among Challenge Stress,Hindrance Stress,and Employees' Innovative Work Behavior: Mediation Effects of Thriving at Work and Emotional Exhaustion

Employees' innovative work behavior (IWB) is one of the key factors in improving organizational competitiveness. Previous studies show that challenge and hindrance stress can impact employees' IWB, but our understanding of the exact mechanism underlying the impact is still limited. The present study employed four scales (Challenge and Hindrance Stress Scale, Thriving at Work Scale, Chinese Emotional Exhaustion Scale, and Employee Innovative Behavior Scale) to collect questionnaire data from 789 employees in diverse organizations via an online platform. A two-path mediation model was constructed. The results show that: (a) challenge stress positively predicted thriving at work and IWB; (b) thriving at work played a partial mediation effect between challenge stress and IWB; (c) hindrance stress negatively predicted thriving at work and positively predicted emotional exhaustion; and (4) hindrance stress did not directly impact IWB while thriving at work and emotional exhaustion were main mediators in the relationship between hindrance stress and IWB. These findings suggest that employees should sensibly cope with different work stresses, while managers should plan work tasks scientifically and give employees adequate opportunities to learn and rest in order to keep them in a positive state to solve problems and work creatively.     

大学生A型行为类型及其学业情绪特点

用A型行为类型量表和大学生一般学业情绪问卷对218名大学生进行了调查。结果发现：被调查大学生中A型行为者（A和A^-）约占25％。大学生的学业情绪以正性情绪为主,A型行为者的比例和学业情绪的得分在性别、年级、专业变量上无显著差异。不同行为类型者学业情绪的特点：B型者（B或B^-）的羞愧、气愤、厌烦、焦虑、自豪、希望、愉快情绪均明显低于A型者（A或A^-）;B型者（B或B^-）的羞愧、气愤情绪明显低于极端中间型者;TH得分高者负性情绪多而不能放松;CH得分高的学生既有羞愧和气愤,又有自豪和希望。     

The Social Phobia Inventory: screening and cross-cultural validation in Spanish adolescents

Availability of brief, self-report measures to be used as screening instruments is crucial to detect correctly youth with social anxiety disorder and therefore, reach those otherwise under-detected and under-treated. A previous study revealed that the Social Phobia Inventory (SPIN) was potentially an appropriate measure for screening social anxiety among US adolescents. However, there is a lack of information concerning its properties as a screening test in other cultures and languages. This is the main objective of this study, although further validity of the scale is provided as well. The sample consisted of 192 adolescents (a sample composed of 114 subjects with a principal diagnosis of social anxiety disorder; and a group consisting of 78 subjects with no diagnosis of social phobia). Results suggest that the Social Phobia Inventory has demonstrated good psychometric properties and indeed may be used as a screening tool in Spanish-speaking adolescents.     

一例一般心理问题的咨询案例分析报告

本文详细介绍了一例因为英语四级考试没有通过引发的一般心理问题的咨询过程。来访者韩某,女,20岁,是一名大二学生,因为英语四级考试没有通过而出现了睡眠质量差,学习效率下降,情绪低落等症状,来访者主动求助于校心理健康中心,迫切希望改变现状,能够正常的学习生活。咨询师在和来访者商议后根据其个性特征和问题的特点采用了合理情绪疗法对其进行干预,帮助她改变了其非理性的信念,经过咨询,来访者情绪好转,可以正确看待困难,取得了比较好的咨询效果。     

组织政治认知对员工行为的影响

组织政治是组织生活的现实反映,是一种普遍现象,员工对组织政治现象的认知对其行为、态度有诸多的不利影响。本研究运用自行研制的组织政治认知调查问卷,通过对29家企业共1647名员工的调查,探讨了在中国文化背景下员工的组织政治认知的结果变量,可望为各类组织的人力资源管理实践提供理论依据。     

数量化维度特征搜索的影响因素探索

有关数量化维度特征搜索的研究表明 ,目标搜索斜率 (反应时间对呈现项目数量函数的斜率 )是由目标与干扰子之间的差异决定的 ,然而以往研究中其差异的值取决于具体的实验条件。根据韦伯定律 ,笔者推测 ,目标搜索斜率应由目标与干扰子之间的相对差异 (C)决定 ,C为目标值 (T)与干扰子值 (D)的差值与该干扰子值的比值。当C值对应相等时 ,不同几何形状刺激的目标搜索斜率应无差异。为此笔者分别采用圆 (实验一 )和三角形 (实验二 )进行实验研究。实验结果支持了上述假设 ,并发现目标大于干扰子时的目标搜索斜率对C值的函数是单调递减函数     

New polytypes of long-period stacking ordered structures in a near-equilibrium Mg97Zn1Y2 alloy

By atomic-scale high-angle annular dark-field scanning transmission electron microscopy, the long-period stacking ordered (LPSO) structures in a near-equilibrium Mg₉₇Zn₁Y₂ (at.%) alloy have been characterised. In addition to 18R and 14H, new polytypes of LPSO structures are analysed and determined as 60R, 78R, 26H, 96R, 38H, 40H, 108H and 246R. All of these LPSO structures feature AB′C′A building blocks with two Mg layers and three Mg layers sandwiched between them. The Bravais lattices and space groups of new polytypes of LPSO structures were easily determined via the newly introduced method. A structural relationship between the LPSOs is proposed.     

抑郁在青少年核心自我评价与自杀意念间的中介作用:基于Bootstrap法和MCMC法的实证研究

考察抑郁在青少年核心自我评价与自杀意念间的中介作用。对502名高中生进行量表测评。通过偏差校正的Bootstrap法和有先验信息的MCMC法求出中介效应值的95%置信区间分别为[-.030,-.011]和[-.024,-.014],提示抑郁的中介效应显著。效应量k2、R2med分别为.124、.104,偏差校正的Bootstrap法抽样5000次后,构建的效应量的95%置信区间分别为[.070,.178]、[.063,.156],两种指标共同验证效应量为中等。研究结果说明抑郁在核心自我评价与自杀意念间起部分中介作用,效应量中等。
