Most small-scale social economies are characterised by their deficiency, lack, and/or difficulty in matching natural data. Against this backdrop, this paper builds a relatively uniform theoretical framework and designs a more economical and objective method for demarcating ecological conservation redlines (ECR) based on sensitivity assessment of ecosystem services. The results show that the sensitivity assessment model designed in this study can identify sensitive zones effectively, and that the ECR in Hubei Province are well within the sensitive zones so identified. The delimited areas based on the sensitive assessment of ecosystem services have great similarities (95%) with the actual ECR areas in Hubei Province. The most ecologically important functional zones (EIFZ) can also be identified using the regional ecological sensitivity coefficient. When the threshold of EIFZ is set higher, the probability that it falls within the ecologically sensitive areas is greater and the ECR delimited by the method proposed in this study will be more reliable. Theoretically, the delimitation of ECR can be inserted at any evaluation level with a grid resolution higher than that of the land use data, which can be used as a supplement to the ECR delimitation method in ecology or geography. 相似文献

The complexity of value‐based management (VBM) is often not captured in empirical research. In particular, potential differences in the extent of VBM implementation are not considered. Firms are predominantly classified dichotomously into either VBM “adopters” or “non‐adopters.” In this study, we aim to fill this gap by introducing a framework to assess differences in the extent of VBM implementation (VBM‐sophistication) based on publicly available data. This approach enables us to study determinants of VBM‐sophistication based on a hand‐collected data set comprising 2,683 firm‐year observations from 16 European countries between 2005 and 2014. Specifically, we investigate (i) whether potential economic benefits associated with VBM implementation lead to a higher level of VBM‐sophistication, and (ii) if this relation is influenced by extra‐organizational institutions (e.g., industry norms). Our results indicate that companies exhibit higher VBM‐sophistication if certain firm characteristics that increase the potential economic benefits of VBM are present. Moreover, our study provides evidence that this effect is enhanced by extra‐organizational institutions that pressure and support firms in realizing the potential benefits of higher VBM‐sophistication. 相似文献

This study examines how accrual manipulations affect firm valuation in the years surrounding the passage of the Sarbanes‐Oxley Act (SOX). We compare the absolute percentage pricing errors of RIM and DCF valuation models for a group of US firms suspected to have engaged in accrual manipulations to avoid a small loss or a small earnings decline vs. ‘Normal’ firms matched on industry, year and size. We find that RIM can better estimate intrinsic value than DCF for the matched Normal firms in the pre‐SOX period, but not so for accrual manipulators, and that SOX mitigates the harmful effect of accrual manipulations, completely eliminating the difference in RIM's accuracy advantage over DCF between Normal firms and accrual manipulators. As a further analysis, we redefine Suspect firms as real‐activity manipulators and find a significant across‐group difference in accuracy wedge in both sample periods, implying that SOX has prompted firms to favor real‐activity manipulations over accrual manipulations. 相似文献

This research looks at post‐2006‐war reconstruction of the southern suburbs of Beirut under the auspices of Hezbollah (the Islamic resistance movement in Lebanon). The project was widely acclaimed as an alternative to current neoliberal planning practices in the Middle East and beyond. Based on a critical reading of the conception of property issues in this planning project, the article argues that this reconstruction presents a new geometry or alternative to the mainstream configuration of neoliberal urbanism, rather than a departure from its precepts. The reason for this is that the adopted language of property corresponds closely with the conception of property advocated by neoliberal planning, one that enshrines private, individual ownership as sacred and desirable and that works to strengthen its model in the city. I further argue that the ‘neoliberal planning regime’ within which Hezbollah's urban intervention occurs is not accidental; rather, it is necessary for the party's control of this space's future and for consolidating its territory in the city. It is hence expected that Hezbollah's planning in the city will produce the same decried effects as neoliberal planning elsewhere in the city rather than usher an innovative, progressive model of planning. 相似文献

The core question addressed in the natural resource‐based view (NRBV) of the firm is how to develop and exploit resources beneficial for both the natural environment and firm performance. Due to the resource constraints and increased competition facing small manufacturing firms, achieving this is a challenge for such companies. Building on the NRBV and resource orchestration literatures, we examine the relationship between green purchasing capabilities (GPCs), CEO's environmental orientation (EO), and firm growth. Results from 304 Swedish small manufacturing firms indicate a significant relationship between GPC and growth, and this relationship is positively moderated by the EO of the CEO. 相似文献

Sales control systems are instruments used by firms to improve performance and other organizational outcomes. To understand their antecedents and consequences, this paper conducts a meta‐analysis based on 104 studies. The results showed significant relationships between behaviour‐ and outcome‐based control systems and the complexity of the products, bonuses, financial performance, sales innovation, organizational support and satisfaction with supervisors. The outcomes revealed that behaviour‐based control systems were the most effective mechanism in turbulent markets and for determining financial performance. However, outcome‐based control systems were the most efficient instrument for complex products. 相似文献

Community based tourism (CBT) offers many opportunities, however, conflict frequently occurs while developing CBT in communities around the world. Despite conflict limiting the potential of CBT, conflict management in CBT has not previously been systematically studied. To investigate conflict and conflict management during CBT, a linear model of conflict management was developed and subsequently tested through a three phase qualitative process: analysis of CBT literature, online international survey of 29 CBT stakeholders, and in-depth interviews of 23 CBT stakeholders. Results endorse the proposed linear model of ‘conflict themes’: an ‘instance’ of conflict, followed by a ‘response’, which results in an ‘impact’. The rich data highlights the complexity involved, which was incorporated into the expanded model with three additional scenarios: ‘new conflict develops’, ‘interrelated conflict themes’, and ‘simultaneous conflict themes’. The complete Conflict Management Model provides stakeholders with a tool to address conflict, thereby improving the outcomes of CBT. 相似文献

This paper studies a robust continuous‐time Markowitz portfolio selection problem where the model uncertainty affects the covariance matrix of multiple risky assets. This problem is formulated into a min–max mean‐variance problem over a set of nondominated probability measures that is solved by a McKean–Vlasov dynamic programming approach, which allows us to characterize the solution in terms of a Bellman–Isaacs equation in the Wasserstein space of probability measures. We provide explicit solutions for the optimal robust portfolio strategies and illustrate our results in the case of uncertain volatilities and ambiguous correlation between two risky assets. We then derive the robust efficient frontier in closed form, and obtain a lower bound for the Sharpe ratio of any robust efficient portfolio strategy. Finally, we compare the performance of Sharpe ratios for a robust investor and for an investor with a misspecified model. 相似文献
