Leveraging middle managers’ brokerage for corporate entrepreneurship: The role of multilevel social capital configurations

Building on recent efforts to bring a socio-political perspective to social capital research, we develop and test a multilevel framework that explains why middle managers who occupy brokerage positions differ in their ability and willingness to engage in entrepreneurial behavior. More specifically, we provide a contextualized understanding of the links among middle managers' brokerage, their political-support ties, and their personal initiative. Results derived from data on 383 middle managers and 72 top managers in 34 business units indicate that political-support ties with top managers strengthen the relationship between middle managers’ brokerage and personal initiative. However, this positive effect depends on the social capital resources available in the focal business unit. It is attenuated in business units with a supportive and trusting social context and amplified in business units with high levels of internal connectedness. By uncovering these incompatibilities and complementarities, our study demonstrates the value of accounting for different social capital configurations and the interplay of their inherent social capital resources when examining the effects of brokerage on corporate entrepreneurship.     

The ecosystem blueprint: How firms shape the design of an ecosystem according to the surrounding conditions

Ecosystems are formed by organisations that jointly create a value proposition that a single firm could not create in isolation. To deliver this value proposition, the partners need a focal firm, the orchestrator, to be align them towards the joint value proposition. Thus, how orchestrators design the alignment structure of an ecosystem is at the very heart of the ecosystem concept – yet it has not been sufficiently addressed by extant research. This is all the more true for the question of how the design of an ecosystem is shaped depending on surrounding conditions. This paper applies a qualitative study with ten cases and, based on the attention-based view of the firm, contributes to research on ecosystems in several ways. First, it explains which ecosystem designs are beneficial under which conditions. Second, it elucidates the structure and activities within ecosystems and shows that start-ups can be just as good ecosystem orchestrators as incumbents. Third, it explains the circumstances under which single vs. multi orchestrator ecosystems occur. Fourth, it presents the conditions when incumbents or start-ups make better orchestrators. Finally, it is among the first studies to apply the attention-based view to business ecosystems, and shows that doing so yields intriguing insights into this emerging field of research.     

The relationship between presenteeism and job satisfaction: A mediated moderation model using work engagement and perceived organizational support

Research on presenteeism has largely focused on its prevalence, determinants and consequences on the health of both employees and organizations. To date, few studies have examined the influence of presenteeism on workers’ attitudinal and motivational responses. Based on the Effort–Recovery Theory, this study evaluates the mediating effect of work engagement in the relationship between presenteeism and job satisfaction. Building on previous work, this study also proposes to consider perceived organizational support as a moderator of the work engagement–job satisfaction relationship. Presented in the form of a mediated moderation model, the results of bootstrapped regression analyses show three main results. First, presenteeism is negatively associated with work engagement and job satisfaction. Secondly, work engagement is one of the factors through which presenteeism influences job satisfaction. Thirdly, perceived organizational support moderates the association between work engagement and job satisfaction so that, at a low level of work engagement, feeling supported by the organization makes a difference on job satisfaction. Overall, this research is part of the limited number of studies that have focused on the interplay existing between presenteeism and its consequences in terms of job attitudes.     

基于长江经济带的金融资源与农业资本化耦合实证研究

农业资本化的本质是农业资本投入的不断增加,金融资源是实现农业资本化的根本保障,只有顺应农业资本化方向的金融资源才可减少无效或低效供给,增加有效或高效供给。本文首先从理论出发论述了金融资源与农业资本化存在相互作用的耦合机制。金融资源通过资本形成机制、技术进步机制和要素替代机制促进农业资本化发展,农业资本化的发展能带来农业生产效率和数量的提高,促进农业经营性收益增加,从而刺激农村地区金融服务产品的需求和供给得到提升,为金融资源总量增加提供累积空间。再基于长江经济带10省市2008—2019年样本数据,通过构建金融资源与农业资本化两大指标体系,运用熵值法和耦合协调度模型对金融资源与农业资本化的耦合协调程度进行实证检验。结果表明,金融资源与农业资本化的发展整体呈上升趋势,但二者存在背离的现象,农村金融资源不足或错配阻碍着金融资源与农业资本化相互促进的良性循环。     

在坚守与转换中思索人性:刘庆邦小说的空间书写

刘庆邦着眼于我国城乡社会结构的变迁,多年来坚持书写农村题材和普通矿工的平凡生活,新世纪以来创作的“保姆在北京”系列小说则将创作视点转移至进城打工的保姆群体,不变的是他对底层百姓的人道主义关怀及对人性问题的深入思索。不论是城乡交叉地带的煤矿叙事所呈现出的物理空间、心理空间和社会空间,还是“保姆在北京”系列小说中空间权力对进城乡下女性的规约与限制,都表现出刘庆邦小说明显的空间意识,也体现了他小说创作的独特价值。     

Origins and destinies: Immigration to the United States since World War II

Contemporary immigration to the United States and the formation of new ethnic groups are the complex and unintended social consequences of the expansion of the nation to its post-World War II position of global hegemony. Immigrant communities in the United States today are related to a history of American military, political, economic, and cultural involvement and intervention in the sending countries, especially in Asia and the Caribbean Basin, and to the linkages that are formed in the process that open a variety of legal and illegal migration pathways. The 19.8 million foreign-born persons counted in the 1990 U.S. census formed the largest immigrant population in the world, though in relative terms, only 7.9% of the U.S. population was foreign-born, a lower proportion than earlier in this century. Today's immigrants are extraordinarily diverse, a reflection of polar-opposite types of migrations embedded in very different historical and structural contexts. Also, unlike the expanding economy that absorbed earlier flows from Europe, since the 1970s new immigrants have entered an hourglass economy with reduced opportunities for social mobility, particularly among the less educated, and new waves of refugees have entered a welfare state with expanded opportunities for public assistance. This paper seeks to make sense of the new diversity. A typology of contemporary immigrants is presented, and their patterns of settlement, their distinctive social and economic characteristics compared to major native-born racial-ethnic groups, and their different modes of incorporation in—and consequences for—American society are considered.     

Generalized Leverage and its Applications

The generalized leverage of an estimator is defined in regression models as a measure of the importance of individual observations. We derive a simple but powerful result, developing an explicit expression for leverage in a general M -estimation problem, of which the maximum likelihood problems are special cases. A variety of applications are considered, most notably to the exponential family non-linear models. The relationship between leverage and local influence is also discussed. Numerical examples are given to illustrate our results

Institutional Ethnography and Experience as Data

Experience, as concept, is contested among feminists as to its epistemological status, thus its usefulness in knowledge claims. Institutional ethnography (Smith 1987) is a feminist methodology that nonetheless relies fundamentally on people's experience. Not as Truth, nor the object of inquiry, but as thepoint d'appui for sociological inquiry. This article offers a demonstration of institutional enthnography using observational and interview data that show experience as methodologically central to a trustworthy analysis. A moment in the work lives of nursing assistants in a long-term care setting is captured by a participant observer. The analysis produces two lines of argument. One is methodological; it is argued that nursing assistants' experiences are an entry into the social relations of the setting that, when mapped and disclosed, make those experiences understandable in terms of the ruling arrangements permeating both the organization and their own experiences. The other argument is substantive; the inquiry uncovers how a quality improvement' strategy in a long term care hospital in Canada is reorganizing caregivers' values and practices toward a market orientation in which care appears to be compromised. Use of experience as data in this approach holds the analysis accountable to everyday/everynight actualities in a lived world.
