This paper addresses the topic of business network dynamics. Starting with a review of the IMP literature, it aims to shed light on potential relational paths by which a firm may reconfigure its business network. To this end, two main emerging paths are described: integration and substitution. Methodologically, the paper presents and discusses the data collected during a longitudinal case analysis of four Italian textile producers. The main implications for business networks stemming from these emerging relational paths are described. In particular, the main findings from the cases analyzed suggest that business network dynamics should be interpreted in terms of the processes of both business network change and consolidation. 相似文献

Akut dekompensierte Herzinsuffizienz - Rund zwei Millionen Menschen in Deutschland
leiden an einer Herzinsuffizienz. Vor allem Dekompensationen des Krankheitsbildes
gef?hrden die Patienten und führen zu wiederholten Krankenhauseinweisungen. Ursache:
Oft falsche Medikamenteneinnahme oder die mangelnde Umsetzung von Verhaltensrestriktionen. Pflegekr?fte müssen bei ihrer Arbeit
daher verst?rkt auf Aspekte der Patientenedukation
setzen. 相似文献

The serial correlation of high‐frequency intraday returns on the Italian stock index futures (FIB30) in the period 2000–2002 is studied. It is found that intraday autocorrelation is mostly negative for time scales lower than 20 minutes, mainly due to the bid–ask bounce effect. Although this supports the efficiency of the Italian futures market, evidence that intraday serial correlation becomes positive in high‐volatility regimes is also provided. Moreover, it is found that it is mainly unexpected volatility that makes serial correlation rise, and not its predictable part. The results are supportive of the K. Chan (1993) model. © 2006 Wiley Periodicals, Inc. Jrl Fut Mark 26:61–84, 2006 相似文献

Asset-Liability Management has gained increased significance within the German insurance industry. This was mainly driven by recent capital market developments. In fact, insurers have encountered challenges to earn given interest guarantees. Regulatory changes also require more sophisticated ALM-tools. Solvency II will change the underlying paradigm and shift balance sheets perception towards a market value oriented view. Especially liabilities will have to be accounted for using the fair value approach. Most ALM-tools appear to be unable to cope with these demands. To improve this current practice, in this paper a Markowitz-approach is employed in order to generate an integrated method for the optimization of assets and liabilities in the life insurance industry. This technique aims to link new regulatory requirements to the latest capital market theory and therefore delivers a procedure for an integrated asset allocation policy in the insurance industry. 相似文献

The purpose of this paper is to investigate the link between corporate social responsibility (CSR) growth and income distribution. We present a general equilibrium model where social responsibility enters both firms' and consumers' decisions. At equilibrium, different degrees of CSR diffusion may arise. We study the conditions under which there exists a virtuous circle which ties increases in the diffusion of CSR to reductions in income inequality. Under certain circumstances, any policy which promotes CSR diffusion induces a reduction in income inequality. By contrast, when such conditions are not satisfied, only redistributive policies may generate the virtuous circle. 相似文献

Sustainable land use planning is crucial for realizing the aim of food security and for combating land degradation in the Sahel. A participatory land use planning workshop was organised in a village in the eastern region of Burkina Faso to investigate land use problems, their causes, effects and possible solutions. Participatory research tools and GIS were combined to get insight into possible conflicts or synergies between different land use options as mapped by different ethnic groups. Pictograms were used to locate alternative land use options on the map, after which they were digitised for analysis with GIS. The workshop confirms the importance of integrating scientific and local knowledge to develop concrete options for sustainable land use that fit to local realities and aspirations. Local people are knowledgeable about the driving forces behind land degradation, they take actions to combat the effects of degradation, and they have concrete ideas about alternative land use options. The use of GIS proved its added value in the participatory process of integrated land use planning. The maps that were produced also facilitate discussions between community members, researchers and government representatives at the regional level, both regarding current land use problems and regarding alternative options as perceived by the local population. 相似文献

Chinese diaspora is one of the most important areas in the field of immigrant entrepreneurship and the Chinese case is, for absolute numbers, entrepreneurship rates and scientific attention, one of the most significant phenomena in the world and in Italy. While much of the literature on the topic focuses on ethnic networks and social ties, there is a lack of studies that acknowledge the role of business networks in the later growth of migrant entrepreneurship, when the importance of social ties within the ethnic community diminishes. This paper tries to answer the following research question: Which is the role of ethnic networks and business networks in the path of evolution of Chinese migrant entrepreneurship? Thus, the paper analyses the structure and characteristics of ethnic networks and business networks and the role of each in the growth and evolution of Chinese migrant entrepreneurship. Our research considers business networks as the main focus of analysis that may replace social ties in consolidating insidership in new business settings and in finding new opportunities. A qualitative methodology is adopted, namely a multiple case study. Five cases of individual Chinese companies settled in a specific area are presented, for which the networks in which they are involved are traced and analysed. The case analysis shows that in the evolution of Chinese migrant entrepreneurship, ethnic networks are very important in the early phases of the business, but the role of cross-cultural business networks becomes relevant for further development. Implications—managerial and for policy makers—are highlighted and discussed. 相似文献

Measuring labor and capital services accurately is essential to obtaining reliable estimates of production functions and total factor productivity (TFP) growth. Using data on the operating time of capital, a series that exists for the French business sector, greatly improves the measurement of effective capital services in production. The ensuing estimation results are consistent with Cobb–Douglas technology under constant returns to scale, with the factor elasticities not statistically different from their income shares. In the same framework, TFP growth is estimated as a latent variable and found to be less volatile than accounting residuals, negatively correlated with employment, and free of cyclicality. It is statistically best estimated as a first-order autoregressive process, with an autoregressive coefficient of 0.95. Total factor productivity growth was estimated to have declined steadily between the mid-1970s and mid-1990s, but the rate of decline has diminished since then. 相似文献
