Forced to compete with private and public sector providers, charities experience tensions as the quest for a more commercially-oriented position may conflict with their social imperative. Little attention has been given to understanding the experiences of local charities as service providers. This paper captures the reactions of those working on the charity front line.  相似文献

Putting climate change policy-integration into practice is challenged by problems of institutional misfit, due to, inter alia, deficient vertical administrative interplay. While most focus within the field of climate change research has targeted the national–local interplay, less is known about the interface of regional and local perspectives. Here, the aim is to study that interface with a specific focus on the relation between regional and local spatial planning actors, through a case-study of transport and coastal zone management in a Swedish municipality. The article is based on interviews (focus group and single in-depth) and official planning documents. The material reveals a tricky planning situation, replete with conflict. In practice, various institutional frameworks, claims and ambitions collide. The attempts to steer the local spatial planning initiatives from the regional level led to conflicts, which in turn seems to have hampered the overall work for climate change management through spatial planning. Furthermore, there are few traces of prospects of a smooth vertical institutional interplay able to support the overall aims related to integrating climate change mitigation and adaptation in spatial planning.  相似文献

Store Brands (SBs) have experienced a strong increase in both value and unit sales internationally during the last decades; thus their market share has been constantly growing. Starting from these considerations, the present work aims at deepening the topic of inter-brand competition within the FMCG market and, in particular, the market share trade-off between Leading National Brands (LNBs) and Store Brands. Our empirical analysis is based on panel data about 322 product categories sold within the Modern Grocery Distribution stores in the 2010–2013 period. Results obtained show: (i) the existence of a relationship between the increase in the LNB-SB price gap and the switching of market share from the former towards the latter; (ii) the consolidation of a change in consumers' purchasing preference in favor of SBs; (iii) the existence of an inverse relationship between the inter-brand competition intensity and the retail branding life cycle evolutionary stage, which is different for each product category.  相似文献

This article picks up a discussion in international business accounting about the appropriate definition and use of conservatism (or prudence) and calls for a similar discussion in public sector accounting. If financial reports present an overly optimistic situation, politicians might use them to justify spending public money that is not there, risking the sustainability of services and ‘borrowing’ from future generations.  相似文献

Knowledge flows are a key source of advantage for multinational corporations (MNCs); however the nuances of knowledge flow practices and their micro-foundations require further theoretical development. Using qualitative data on 40 cases of subsidiary managers’ knowledge mobilizations, this paper unravels micro-level practices of knowledge flows in MNCs. We find that subsidiary managers’ knowledge mobilizations initiate a complex pattern of subsidiary knowledge inflows, pinpointing the significance of lateral and bottom up exchanges (locally as well as internationally). We use these insights to distinguish between two types of subsidiary knowledge flows: deliberate and emergent, and discuss how their differences have profound implications for the investigation of MNC knowledge flows and their micro-foundations.  相似文献

Continuous exact non-atomic games are naturally associated to certain operators between Banach spaces. It thus makes sense to study games by means of the corresponding operators. We characterize non-atomic exact market games in terms of the properties of the associated operators. We also prove a separation theorem for weak compact sets of countably additive non-atomic measures, which is of independent interest.  相似文献

Resilience – a firm's ability to adapt, endure, quickly bounce back, and then thrive despite a catastrophic event – addresses diverse managerial constructs including performance (Carmeli & Markman, 2011). Our exploratory study expands this line of research by making two contributions: first, we develop and test a new revelatory measure for resilience – VOLARE – combining financial performance measures with volatility data. Then, applying this new measure to the financial industry, from 2002 to 2011, we identify highly resilient international financial services firms (IFSFs; e.g., banks) and compare them with less resilient IFSFs. Second, we assess three factors – bank size, home-market solidity, and product and market complexity – that the literature has traditionally shown to be highly predictive of banks’ performance. Consistent with our expectations, the results corroborate that VOLARE is complementary to, but distinct from, traditional financial measures of firm performance. We explain these deviations from traditional studies and suggest further research topics.  相似文献

Heuristic algorithms have been widely used to provide computationally feasible means of exploring the cost effective balance between grid versus off grid sources for universal electrification in developing countries. By definition in such algorithms however, global optimality is not guaranteed. We present a computationally intensive but globally optimal mixed integer non-linear programming (MINLP) model for electricity planning and use it in a Monte Carlo simulation procedure to test the relative performance of a widely used heuristic algorithm due to [28]. We show that the overall difference in cost is typically small suggesting that the heuristic algorithm is generally cost effective in many situations. However we find that the relative performance of the heuristic algorithm deteriorates with increasing degree of spatial dispersion of unelectrified settlements, as well as increasing spatial remoteness of the settlements from the grid network, suggesting that the effectiveness of the heuristic algorithm is context specific. Further, we find that allocation of off grid sources in the heuristic algorithm solution is often significantly greater than in the MINLP model suggesting that heuristic methods can overstate the role of off-grid solutions in certain situations.  相似文献

通过GIS空间分析功能,选取常德市的四个县市:桃源县、汉寿县、临澧县、津市市,从土地利用现状、土地利用时空变化、土地利用类型动态度、土地利用程度变化以及土地利用变化区域差异等五个方面对常德市2009年和2012年土地利用、覆被变化进行定量、定性分析比较。研究结果表明:12009-2012年期间,四个县市的城镇、交通水利等建设用地需求持续增加;2 2009-2012年期间,土地利用程度综合指数呈增长的趋势;3常德市2009-2012年间土地利用程度变化不大,并且区域不平衡;4 2009-2012年期间,四个县市中相对变化最大的为临澧县城镇建设用地。  相似文献
