We propose to bridge the domains of positive health and leadership. We suggest that a “positive” health model helps explain highly effective leadership. The leader must strive for health and facilitate health in his/her followers. We look at leadership through this new and positive lens, that of “positive” health promotion.

Character (ethos) refers to those interpenetrable habitual qualities within individuals, and applicable to organizations that both constrain and lead them to desire and pursue personal and societal good. In our Incubator article, we undertake two objectives. First, we provide our conceptualization of character; briefly specifying what character is and is not. Second, we introduce several promising directions for organizationally based research on character. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

Sustainability has become a fundamental concern in today' world—one which firms can no longer remain oblivious to. Through CSR, companies can shore up financial sustainability by acting in responsible, socially and environmentally sustainable ways. Yet the vast majority of literature addressing this phenomenon to date has focused almost exclusively on developed economies. The objective of the present study, therefore, is to contribute to filling this gap by analyzing the potential impact of CSR on sustainable financial value in the context of an emerging economy, Peru. To this end, we used the PLS technique to carry out quantitative analysis of data from a sample of over 200 managers at Peruvian companies. Our model is based on the premises of Social Capital Theory and Theory of Resources. Specifically, we analyze the extent to which CSR impacts corporate reputation, brand image and financial value in the context of an emerging economy. Our data indicate that—unlike more developed economies—in emerging economy contexts, direct relationships linking CSR and company financial value are lacking, though may occur by way of the path CSR > reputation > brand image > financial value. We also find that size moderates this path, while the sector of activity does not moderate the causal model. Hence, we suggest that both the cross‐cultural component and differing degrees of economic development and market maturity affect the perceived impact of CSR on financial value. The present study is pioneering in that it analyzes the impact of sustainability on financial value from the perspective of managers in an emerging economy context. Key theoretical and practical implications of our findings are provided in the final section of the paper. 相似文献

Carbon fibre reinforced polymer (CFRP) composites are increasingly employed in an extensive range of applications, such as aerospace, automotive, or renewable energy. Consequently, the establishment of a composite recycling sector will become necessary in the future. The French national agency for research had funded a project named SEARRCH, which indicates “Sustainability Engineering Assessment Research for Recycling Composites with High value” to initiate stakeholders engagement for the implementation of the CFRP recycling sector in a sustainable way. This publication aimed at giving the results and the advantages of using a participatory research approach for the implementation of a recycling sector that follows the concept of sustainable development. This participatory research approach was conducted based on a panel of 40 stakeholders from different stages of the CFRP life cycle: CFRP producers, end‐of‐life management, institutional/normative, and research groups. A statistical quantitative analysis of 230 different criteria extracted from the interviews has demonstrated that “quality,” “mastering recycling process,” “norms and regulations,” and “maturity of the recycling process” are the most cited criteria by stakeholders. A qualitative analysis shown that, the future sustainable composites recycling sector would be utilised as a multiprocess sector that addresses a multiplicity of markets, requires the involvement of leaders and introduction of incentive tools and needs improvement regarding the maturity of recycling technologies to satisfy economic and environmental goals. 相似文献

It has been proposed that a considerable amount of CO2 can be safely sequestered from the atmosphere in geological formations such as coalbeds. In spite of promising evidence of the economic and technical viability of CO2 sequestration in coal seams, many of its hydro‐geomechanical aspects are not fully understood. This paper presents a coupled hydro‐mechanical model that is used to assess the reservoir performance of a coalbed and the induced surface and subsurface deformations. A series of numerical simulations has been performed to study the effects of different parameters on the reservoir and geomechanical behaviors associated with CO2 injection. A single‐phase dual‐porosity model is coupled to a one‐dimensional poroelastic model and an analytical model for the ground surface movements. Through these simulations, the role of three sets of parameters at different scales is investigated: fracture characteristics, matrix characteristics, and geomechanical/geometrical characteristics. The comparative impacts of these parameters on reservoir permeability, volume of the stored CO2, and deformations of the coalbed and the ground surface, are quantitatively assessed, in order to identify the most important parameters influencing the hydro‐mechanical response of the ground. 相似文献

The kinetic and thermodynamic studies of CO2 adsorption on activated carbon were carried out in a fixed bed. Six different CO2 concentrations (from 5% up to 18 vol.%) and four temperatures (303 K, 313 K, 323 K, and 333 K) were applied to investigate dynamic adsorption behaviors. It showed that the increase in temperature led to faster adsorption kinetics, but also reduced the adsorption capacity. An isotherms modeling was made by the Langmuir isotherm model. The experimental isotherms data were well fitted. Then, based on the adsorption isotherms, the isosteric heats of CO2 adsorption were determined by Clausius‐Clapeyron equation. The calculated isosteric heat declined slightly with the adsorbed amount on activated carbon, and had an average value of 16.09 kJ/mol, which is much lower than the actual heat of adsorption measured by calorimeter. Moreover, regeneration experiments by vacuum evacuation (<10 kPa) were conducted to assess the regeneration efficiency (RE) of activated carbon. Regeneration efficiency increased with the reduction of vacuum pressure and reached over 90% at the vacuum of 4 kPa. A temperature swing integrated into the vacuum evacuation process resulted in a remarkable increase of RE with an increase in regeneration temperature, which confirmed the favorable effect of temperature on regeneration of activated carbon and providing almost full regeneration. © 2016 Society of Chemical Industry and John Wiley & Sons, Ltd 相似文献

Abstract: A decision support system for sustainable water resources management in a water conflict resolution framework is developed to identify and evaluate a range of acceptable alternatives for the Geum River Basin in Korea and to facilitate strategies that will result in sustainable water resource management. Working with stakeholders in a “shared vision modeling” framework, sustainable management strategies are created to illustrate system tradeoffs as well as long‐term system planning. A multi‐criterion decision‐making (MCDM) approach using subjective scales is utilized to evaluate the complex water resource allocation and management tradeoffs between stakeholders and system objectives. The procedures used in this study include the development of a “shared vision model,” a simulated decision‐making support system (as a tool for sustainable water management strategies associated with water conflicts, management options, and planning criteria), and the application of MCDM techniques for evaluating alternatives provided by the model. The research results demonstrate the utility of the sustainable water resource management model in aid of MCDM techniques in facilitating flexibility during initial stages of alternative identification and evaluation in a basin suffering from severe water conflicts. 相似文献

Deliberation over and relative preference for general or specific (broad or narrow) constructs has long been an important issue in organizational behavior research. In this article, we provide a review of this general issue and some specific recommendations for researchers. We begin by discussing whether the general versus specific issue is an important debate and by discussing other underlying issues (the role of researcher preferences, distinction between reflective and formative indicators, and distinction between constructs and measures of constructs). Building on Chen's (this issue) analysis of core self‐evaluations, we first discuss how the general–specific debate has progressed in core self‐evaluations research. We then discuss three other important areas in which this debate has played out: intelligence, five‐factor model of personality, and job attitudes. Finally, we offer a framework to help guide decisions about whether to utilize general measures, specific measures, or both and conclude by providing recommendations for the use of general and specific measures in organizational behavior research.
