Our study explores the structuring decisions made by intermediaries seeking to alleviate poverty by connecting base‐of‐the‐pyramid markets with more developed markets. Using intermediation theory to ground our study, we collected qualitative data on 29 social intermediation projects located within Latin America, Africa, and Asia. Our findings suggest that ‘socializing’ intermediation theory to more accurately explain and predict structural outcomes across more diverse contexts requires three key modifications: (1) the attenuation of opportunism, which creates an internalizing social force; (2) the accommodation of non‐monetary objectives, which creates an externalizing social force; and (3) the perception of transaction capabilities as tractable, which serves as a guidepost for reconciling these two opposing social forces.  相似文献

In this paper we discuss the analysis of data from population‐based case‐control studies when there is appreciable non‐response. We develop a class of estimating equations that are relatively easy to implement. For some important special cases, we also provide efficient semi‐parametric maximum‐likelihood methods. We compare the methods in a simulation study based on data from the Women's Cardiovascular Health Study discussed in Arbogast et al. (Estimating incidence rates from population‐based case‐control studies in the presence of non‐respondents, Biometrical Journal 44, 227–239, 2002).  相似文献

One‐sample and multi‐sample tests on the concentration parameter of Fisher‐von Mises‐Langevin distributions on (hyper‐)spheres have been well studied in the literature. However, only little is known about their behaviour under local alternatives, which is due to complications inherent to the curved nature of the parameter space. The aim of the present paper therefore consists in filling that gap by having recourse to the Le Cam methodology, which has recently been adapted from the linear to the spherical setup. We obtain explicit expressions of the powers for the most efficient one‐ and multi‐sample tests. As a nice by‐product, we are also able to write down the powers (against local Fisher‐von Mises‐Langevin alternatives) of the celebrated Rayleigh test of uniformity. A Monte Carlo simulation study confirms our theoretical findings and shows the empirical powers of the above‐mentioned procedures.  相似文献

This essay is concerned with the planning and densification of suburbs, which present a huge challenge insofar as they form a large area of urbanized land that remains underexploited due to low residential density. Drawing on current research in the Paris city‐region, the essay focuses specifically on the difficulty in implementing densification policies in low‐rise suburban areas. It examines the varying degrees of densification fostered by these policies, and builds upon recent urban studies literature on suburban change to trace how suburban areas are being transformed through regulations, instruments and market dynamics associated with densification processes. What kinds of densification policy are being implemented and what are the socio‐economic, political and cultural determinants of each type of regulatory approach? This essay will attempt to answer this question via an analysis of the densification policies being put in place in the municipalities of the Paris city‐region. It will offer in turn a typology of these different policies. It shows that densification is an instrument that can be used to address local political concerns which vary greatly depending on the economic, social and geographical position of municipalities within larger urban areas.  相似文献

Statistical methodology for spatio‐temporal point processes is in its infancy. We consider second‐order analysis based on pair correlation functions and K‐functions for general inhomogeneous spatio‐temporal point processes and for inhomogeneous spatio‐temporal Cox processes. Assuming spatio‐temporal separability of the intensity function, we clarify different meanings of second‐order spatio‐temporal separability. One is second‐order spatio‐temporal independence and relates to log‐Gaussian Cox processes with an additive covariance structure of the underlying spatio‐temporal Gaussian process. Another concerns shot‐noise Cox processes with a separable spatio‐temporal covariance density. We propose diagnostic procedures for checking hypotheses of second‐order spatio‐temporal separability, which we apply on simulated and real data.  相似文献

This study addresses organization‐based self‐esteem (OBSE) development by examining the role of perceptions of employer psychological contract fulfillment, and the self‐regulatory processes by which OBSE evolves and produces its effects. Self‐regulatory theory helps reveal why psychological contract fulfillment relates to OBSE, how OBSE mediates its effects, and the ways in which OBSE might interact with perceived employment opportunities to affect job satisfaction, performance, and turnover intentions. The results show that OBSE is related to and mediates the relationships between relational contract fulfillment and employee job satisfaction and performance, but OBSE is not related to transactional contract fulfillment. Nor does OBSE mediate the relationships between transactional contract fulfillment and the dependent variables. Perceived employment opportunities moderate the relationships of OBSE with job satisfaction and turnover intentions. This study concludes with recommendations of ways managers can increase their sensitivity to the types of messages they communicate to employees. © 2014 Wiley Periodicals, Inc.  相似文献

As the circular economy (CE) concept gains growing popularity among consumers and producers, small‐ and medium‐sized enterprises (SMEs) increasingly look for ways to reorganize their offering and operations to integrate into the CE. This study examines the impact of (a) circular eco‐innovations and (b) external funding available for CE activities on the growth of European SMEs using a data set of 5,100 SMEs across 28 European countries in 2016. Findings reveal that a significant threshold investment (i.e., higher than 10% of revenues) into circular eco‐innovations is required for SMEs to benefit from investing into the CE. Moreover, the majority of circular eco‐innovations fail to boost the growth rates of SMEs, with the exception of investments into eco‐design innovations. Although traditional forms of debt and grant finance targeted to CE activities are found to have no or negative impact on the growth of SMEs, equity finance (i.e., angel and venture capital investments) contributes positively to their growth. The study offers insights into the lower levels of SME engagement in the CE as well as policy implications for improving engagement.  相似文献

Through reflection on the practical post‐apartheid (re)alignment of competing rationalities across the Greater Durban urban region, this essay teases out the interface between traditional and modern settlement management systems, and explores how governance cleavages are being renegotiated and mediated. It is suggested that, in building an integrated method of operating across the fragmented city‐regional scale and navigating the competing interests involved, the practice of African urbanism is being defined. Without making any claims for what may or may not be uniquely African city‐regional dynamics at the boundaries of tradition and modernity, what is clear from the Durban case is that both conventional city‐regional literature and new city‐regional ideas have glossed over the complexity of finding solutions to tensions between poor communities, urban managers, elected local authorities and the traditional rural elites of the functional city‐regions of Africa.  相似文献

While earlier research has shown that regional restructuring after reunification has led to broad de‐industrialization processes in eastern Germany's chemical industry, this article focuses on how re‐bundling processes at the corporate level have stimulated adjustments to the changing economic and political environment leading to a renewed regional development trajectory. The analysis is based on a conceptualization that assesses diachronic processes of rupture and re‐bundling by applying a bottom‐up perspective of how corporate adjustments and restructuring processes generate re‐bundling types that manifest themselves in broader regional re‐bundling scenarios. The empirical analysis focuses on a qualitative case study of Bitterfeld‐Wolfen, the eastern region with the largest chemical industry. The research provides evidence that, although new firm formation has remained weak and acquisitions of chemical multinationals have generated structures only tenuously embedded in the regional economy, modernization and re‐bundling process have contributed to a renewed, smaller yet stable, regional chemical industry. The analysis further shows that the associated processes depended on the roles of individual industrial leaders in the region, who acted as network builders, mobilized joint action and stimulated the development of a collective regional spirit.  相似文献

Nonprofit arts organizations face conflicting objectives to balance—or more specifically, to create—artistic and educational value and to generate financial income from various sources. Pay‐what‐you‐want (PWYW), a participative pricing mechanism where services have no fixed price and customers actively decide what to pay, is a novel pricing mechanism and is of high interest for organizations and researchers alike. Based on the concepts of loss aversion and gain, this study presents a field experiment to test the effects of different PWYW pricing strategies on the amount of money paid by visitors of a German photo biennial. Explicitly, the provisions of minimum, maximum, and suggested external reference prices are compared to a setting with no external reference prices. We test the derived hypotheses, discuss the results, and provide implications for future research, as well as for the management of nonprofit arts organizations.  相似文献

Research on projects is not only an immature field of research, but it is also insubstantial when it comes to understanding what occurs in projects. This article contributes to making project management research matter to the academic as well as to the practitioner by developing a project‐as‐practice approach, in alignment with the ongoing debate in social science research. The article outlines a framework and argues that there are two major challenges to the researcher and also suggests how these challenges can be met. Underlying notions of the practice approach are outlined to ensure a development of the project‐as‐practice approach that makes project management research matter!  相似文献

Despite consensus in the literature that regulation, technology push, and market pull drive eco‐innovation (EI), evidence remains limited on the diverse firm capabilities needed to boost EI. Building on the natural‐resource‐based view of the firm and the EI literature, this paper posits that firms need to renew and realign their capabilities, and ultimately develop distinctive sustainability‐oriented capabilities, in order to meet the rapidly changing regulatory, technology, and market demands. Results of the analysis, based on a survey of U.K. firms, reveal that EIs are more likely to arise when firms (a) build capabilities on voluntary self‐regulation (i.e., executive driven environmental management system and corporate social responsibility) because such organizational capabilities allow them to address increasing regulatory pressures; (b) invest in environmental research and development (i.e., eco‐R&D)—instead of generic research and development—because it provides them with the relevant and specific technological capabilities to tackle technology shifts towards sustainability; and (c) develop capabilities in green market sensing as such capabilities allow them to address green consumption needs.  相似文献

Professional service firms (PSFs) play an important role in the knowledge‐based economy. Their success is highly dependent on their people, the knowledge resources they possess, and how they use these resources. However, how to systematically manage human resources to attain high performance is not fully understood. This study addresses this issue by investigating the linkage mechanisms through which high‐performance work systems (HPWS) influence the performance of PSFs. We integrate resource‐based and dynamic capability theories in order to identify and investigate two intervening mechanisms that link HR practices to firm performance. The first mechanism is the intellectual capital resources comprising the human, social, and organizational capital that HPWS create. The second mechanism is the uses to which both HPWS and resources can be applied, operationalized as organizational ambidexterity, the simultaneous exploitation of existing knowledge and exploration of new knowledge. These mechanisms are hypothesized to link HPWS to firm performance in the form of a practices‐resources‐uses‐performance linkage model. Results from a longitudinal study of 93 accounting firms support this linkage model. © 2015 Wiley Periodicals, Inc.  相似文献

This paper examines the process linking high‐performance work systems (HPWS) and organisational ambidexterity both at the unit and firm level of analyses by integrating strategic HRM, human capital and social capital perspectives. Multisource and multilevel data from 2,887 employees and 536 managers of 58 banks was collected. Results revealed that firm‐level HPWS were positively related to unit‐level employee human capital. Unit‐level employee human capital partially mediated the relationship between firm‐level HPWS and unit organisational ambidexterity. Furthermore, firm‐level social climate moderated the effect of firm‐level HPWS on unit organisational ambidexterity through unit‐level employee human capital. This paper contributes to HPWS and ambidexterity research by revealing the impacts of firm‐level HPWS and mediating mechanisms, as well as identifying boundary conditions for pursuing unit‐level organisational ambidexterity.  相似文献

The present study examines the direct and moderating effects of an international career orientation in the relationship between frequency and duration of international business traveling and work‐to‐life conflict and enrichment. In addition, the effort‐reward imbalance that potentially features in the international business traveler's job was examined in relation to work‐to‐life conflict and enrichment. The study was conducted among 232 Finnish people in jobs requiring international business travel. A moderated hierarchical regression analysis shows that travel of considerable duration and a pronounced effort‐reward imbalance had direct links to work‐to‐life conflict. In contrast, low effort‐reward imbalance and a strong international career orientation had direct links to work‐to‐life enrichment. In addition, having a strong orientation to an international career decreases work‐to‐life conflict when a job requires very frequent traveling, but the moderation effect was not found in relation to duration of traveling. Our findings indicate that interventions aimed at reducing work‐to‐life conflict and increasing work‐to‐life enrichment among international business travelers should focus on fostering a balance between efforts and rewards at work. The extent of employees’ internationalism should also be considered when recruiting people into jobs involving international business travel. © 2014 Wiley Periodicals, Inc.  相似文献

This article develops a new perspective on urban growth machines through an analysis of the relationship between Pittsburgh's Renaissance and cold‐war‐era anti‐communism. In order to facilitate urban (re)development, growth machines foster a shared sense of metropolitan citizenship and a corresponding ideological belief that coalitions of business, government and other elite actors can renew regions for the collective good of their residents. During the early years of the cold war, anti‐communism was a key means by which growth machines could create this shared sense of metropolitan belonging. The members of Pittsburgh's widely celebrated growth coalition used anti‐communism to advance their interests in four key ways: (1) by encouraging residents to see the Renaissance as part of the larger struggle against communism; (2) by eliminating a deeply rooted radical political culture; (3) by, in the process, curtailing opposition to their effort to remake the region into a post‐industrial economy based on free capital mobility; and (4) by having it serve as a shared tactic and ideology that stitched together and legitimated capitalist development at all scales from the factory to the globe. Pittsburgh's Renaissance provides an important example of how growth machines not only produce space, but also citizenship and the conditions of political possibility.  相似文献

The aim of this research was to explore relations between work and family demands and resources, work‐to‐family conflict (WFC), and work and family outcomes in a cross‐cultural comparative context involving Taiwanese and British employees. Two‐hundred and sixty‐four Taiwanese employees and 137 British employees were surveyed using structured questionnaires. For both Taiwanese and British employees, work and family demands were positively related to WFC, whereas work resources were negatively related to WFC. Furthermore, WFC was negatively related to family satisfaction. More importantly, we found that nation moderated relationships between work resources and WFC, WFC and work, and family satisfaction. Specifically, work resources had a stronger protective effect for Taiwanese than British in reducing WFC, whereas WFC had a stronger detrimental effect on role satisfaction for British than Taiwanese. It is recommended that both culture‐general and culture‐specific effects should be taken into consideration in designing future WFC research and familyfriendly managerial practices. © 2010 Wiley Periodicals, Inc.  相似文献
