创业者个体学习、组织学习如何交互影响企业创新行为？——基于整合视角的纵向单案例研究

社会经济的不断发展促使分工愈发精细,对个人与组织间的技术隔离也愈加明显,亟待创业者个体及组织开展跨层次的交互学习以构建组织创新优势。基于此,本文援引学习理论与意义构建视角,从"行动"与"解释"出发,采用纵向单案例研究方法,基于"个体-组织"整合性分析框架,探究了不同创业阶段内跨层次行动主体间的学习互动模型,揭示了其对企业创新的影响路径。研究发现:创业者个体学习与组织学习间的互动,表现为渐变初期个体利用式学习经"自上而下"团队互动主导形成组织单环式行动;而在调整转变期,个体学习与组织学习发生交互影响,包含个体探索式学习经"横向协同式"团队互动主导形成组织双环式行动,以及组织双环式行动转换为单环式之后,经由持续反思与质询,刺激形成创业者个体利用式学习;最后,在发展突变期,个体利用式学习经"制度化统筹式"团队交互合作促成组织单环式行动,同时个体探索式学习经"跨越层次自主式"团队交互激活组织双环式学习。此外,在不同创业阶段,3种互动逻辑与意义构建框架下的创新决定机制呈现出以个体创意激发与扩散、信息整合与匹配以及平衡矛盾与冲突3种不同的影响路径展开的态势。本研究为创业学习理论和创业实践过程贡献了新的启示。     

The Haunting of Shame: Autoethnography and the Multivalent Stigma of Being Queer,Muslim, and Single

Sociology has neglected the terrain of the gay Muslim single as a sociological phenomenon. Produced and managed via meaningful social conduct, the gay Muslim single often holds negative symbolic and cultural worth, one of lacking identification and presence. The stigma of the gay Muslim single is actively reproduced through social and power relations. I examine multiple stigmas and dichotomies by using autoethnography to illustrate the human lived experience of a gay Muslim single, who is silenced, invisibilized, and embodies a social life of “emptiness.” The gay Muslim single, bringing about a “moral panic,” confronts temporal regulations, norms, and values, notably those of heterosexual ones in everyday social life. He is cast as an “outsider,” which reinforces his stigma in everyday social life.     

A Network Therapy Clinic for Clients with Intellectual Disability

Over the past 30 years a systemic approach has been applied to complex cases involving intellectual disability and behaviours of concern. This paper describes a model that draws on systemic family therapy and network therapy as well as the use of a reflective team. A single session intervention was provided for families of people with intellectual disability. A systemic consultation was used as a pre‐session meeting for professionals working with the family. The systemic consultation and single session therapy allowed the family and the professional network to gain insight. Involving the professionals in the therapy session also enhanced the alliance between professionals and family. This approach assists everyone involved in the case to find a way to progress.     

考虑柔性和间隙的螺旋引纬机构仿真分析

为了提高引纬机构的稳定性和精度,将柔性构件和间隙的影响考虑在内,联合ANSYS和ADAMS建立螺旋引纬机构的刚柔耦合模型,通过ADAMS进行动力学仿真,在刚性系统和刚柔耦合系统中分别分析了旋转铰间隙对剑杆输出特性曲线的影响。在对仿真数据的观察中发现了相当比例的噪声信号,为了消除噪声信号的影响,利用统计学中上下四分位数和中位数来识别替换异常值;在综合考虑间隙和柔性构件的影响时,利用减噪后的加速度曲线与理想刚体系统下的数据的偏差值得到一个新的曲线,该曲线在固定区间内做高频波动,呈现出类似周期性声波信号的特点。结果表明旋转铰间隙是影响剑杆稳定性和精度的主要因素,柔性构件和间隙的综合作用产生了趋向于周期性的碰撞影响。依据研 究结果可以进一步对原刚体模型下设计的引纬机构进行优化设计。     

Sex Differences in Parenting Behaviors in Single‐Mother and Single‐Father Households

Research on family structure has led some to claim that sex‐based parenting differences exist. But if such differences exist in single‐parent families, the absence of a second parent rather than specific sex‐typed parenting might explain them. We examine differences in mothering and fathering behavior in single‐parent households, where number of parents is held constant, and we describe individualist and structuralist perspectives for potential sex‐based parenting behaviors. We compare 3,202 single mothers and 307 single fathers in the Early Childhood Longitudinal Study (Kindergarten Cohort). Results suggest that, although there are small differences in the parenting behaviors of single mothers and single fathers, differences are sensitive to demographic disparities and do not translate to academic deficits for children in either family type.     

Single Custodial Fathers' Involvement and Parenting: Implications for Outcomes in Emerging Adulthood

Using a sample of 3,977 youths from the National Longitudinal Survey of Youth (NLSY97), this study examines the unique characteristics of single‐custodial‐father families with adolescents and the effects of single fathers' involvement and parenting on outcomes in emerging adulthood. Findings suggest that single‐custodial‐father families are distinct from single‐mother and 2‐biological‐parent families in terms of sociodemographic characteristics, parenting styles, and involvement. Parenting styles and involvement mediate the differences between single‐father families and 2‐parent families in terms of high school completion and disconnectedness and partially mediate differences for single‐custodial‐father families with a partner. Family and sociodemographic characteristics are also associated with being disconnected for adolescents residing with a cohabiting custodial father.     

Queering the Spinsters: Single Middle-Class Women in Norway, 1880–1920

ABSTRACT

Constituting what may be called “a community of spinsters,” Norwegian middle-class unmarried woman played an important role in undermining and destabilizing the heterosexual cultural matrix during the period 1880–1920. In their anti-sexuality, self-sufficiency and hatred of men the spinsters challenged the heteronormativity of the period, and their queerness still presents a challenge to the harmony-oriented, heteromormative Norwegian women's history.     

Linear estimation for the extended exponential power distribution

Tiao and Lund [The use of OLUMV estimators in inference robustness studies of the location parameter of a class of symmetric distributions. J Amer Statist Assoc. 1970;65(329):370–386] tabulated the coefficients of the best linear unbiased estimators (BLUEs) of location and scale for a particular family of symmetric distributions. This family was a reparameterization of the extended exponential power distribution (EEPD) with the shape parameter restricted to be greater than or equal to one. In this work, we consider the BLU estimation of the location and scale parameters of the EEPD when the shape parameter is one-third and one-half. We obtain closed-form expressions for the single and product moments of the order statistics when the shape parameter is in general in the form of a reciprocal of an integer. These expressions are then used to determine the BLUEs and the corresponding variances for complete samples of size 20 and less. We consider some other linear estimators of the location and scale parameters and then compare them with the BLUEs. Finally, we present a numerical example to illustrate the developed results.
