环境不确定下企业孵化网络治理机制对治理绩效影响研究

从企业孵化网络本身以及环境视角分析了企业孵化网络治理绩效的影响因素,通过企业孵化网络治理机制对治理绩效关系的实证分析,验证了环境不确定下企业孵化网络的契约治理机制、管理治理机制对治理绩效的影响。结果表明:企业孵化网络治理机制中的契约治理机制、关系治理机制对治理绩效具有正向调节作用;环境不确定性会扩大或缩小治理机制对治理绩效的作用强度。企业孵化网络在高市场不确定性环境下,采用关系治理机制的绩效较好;在高技术不确定性环境下,采用契约治理机制的绩效较好。     

Altruistic or egoistic: Which value promotes organic food consumption among young consumers? A study in the context of a developing nation

The present research attempts to understand the importance of altruistic and egoistic value in determining the young consumers’ intention to buy organic food. Environmental concern was considered as the altruistic value, whereas health concern as egoistic value. Using the convenience sampling method, a total of 304 usable responses was collected from young consumers, with the help of self administered questionnaire survey approach. Data analysis was done using two step structural equation modeling (SEM) approach, i.e. measurement model and structural model. Findings indicated that, both altruistic as well as egoistic value influences the intention to buy organic food among young Indian consumers. However, egoistic value was found to have more impact on the consumers’ organic food purchase intention. The present research is one of the initial attempts in the Indian context to understand the importance of values (altruistic and egoistic) organic food consumption among young consumers.     

A multi-objective sustainable load planning model for intermodal transportation networks with a real-life application

Growing importance of intermodal transportation necessitates modeling and solving load planning problems by taking into account various complex decisions simultaneously like transportation mode/service type selection, load allocation, and outsourcing. This paper presents a mixed-integer mathematical programming model for a multi-objective, multi-mode and multi-period sustainable load planning problem by considering import/export load flows to satisfy transport demands of customers and many other related issues. Several multiple objective optimization procedures are utilized in order to handle conflicting objectives simultaneously under crisp and fuzzy decision making environments. A real-life case study is also performed to present application and usefulness of the proposed model.     

Indoor air quality in mass catering plants: Occurrence of airborne eumycetes in a university canteen

The present study aimed to investigate the viable eumycetes population of indoor air sampled in a mass catering plant that produces up to 1200 meals per day. The combination of a culture-dependent and -independent approach applied in the food-processing environment was efficient for the identification of airborne eumycetes. Penicillum, Cladosporium and Alternaria were the dominant genera, while Thysanophora, Aspergillus, Rhizopus, Annulohypoxylon, Arthrinium, Aureobasidium and Trametes were found to be in minority. The size and composition of the eumycetes population found in this study do not raise specific concerns. Nevertheless, a quantitative and qualitative monitoring of these bioaerosol should be included in the progress and criticality reports of the HACCP system in the catering services where eumycetes can pose different risks, such as worsening of the overall quality of meals and/or of the work environment. Indeed, these reports are a useful tool in the preventive HACCP approach, provided that an adequate frequency of sampling is planned in order to quicken the pre-warning process.

中央企业上市公司环境责任与公司价值的相关性研究

本文以中央企业上市公司为样本,讨论国有企业环境责任与公司价值之间的关系。文章在控制公司规模、行业竞争力等变量的条件下,回归结果发现：中央企业上市公司环境责任与公司价值之间存在正相关关系,但不显著。因此,很难认为公司承担更多环境责任能够促进公司价值的增长。     

Who cares about the environment? An empirical analysis of the evolution of political parties’ environmental concern in European countries (1970–2008)

Why do parties offer environmental policies in their political programs? While a number of papers examine the determinants of citizens’ pro-environmental behaviour, we know little about the extent to which political parties adjust their platform towards environmentalism. We investigate this process through data provided by the Manifesto Project Dataset (CMP) for 20 European countries over the period 1970-2008. Following the literature on public concern towards environment, we examine economic, environmental and political determinants. Our findings provide evidence that political parties’ environmental concern is strongly correlated with their political ideology and with country-level economic conditions.     

Revisiting carbon disclosure and performance: Legitimacy and management views

With corporate disclosure of carbon emissions rapidly increasing, the long-standing question remains whether carbon disclosure has any influence on the improvement of carbon performance. Previous studies of environmental disclosure and performance have predominantly focused on whether disclosure is a substitute for poor performance. Little attention has been devoted to the more important question about how changes in disclosure may lead to subsequent changes in performance over time. Following the rationales taken by the legitimacy and management perspectives, we revisit the relationship between carbon disclosure and performance, with a focus on changes that disclosure may (or may not) create. Using a change analysis of Global 500 companies and their carbon emission and disclosure data released between 2008 and 2012, this study finds that the change in carbon disclosure levels is positively associated with a subsequent change in carbon performance (examined through direct and indirect carbon emission intensities). Thus, regardless of whether disclosure has been used as a legitimising tool for prior poor performance, this study confirms that carbon disclosure motivates companies and creates an ‘outside-in’ driven effect for subsequent change and improvement in carbon performance. However, the association between changes in carbon disclosure and performance is relatively weaker in high energy-intensive firms.

Exploring the design of conscious media

Our existing model of media, based upon a consumptive-materialist–atomistic orientation, falls short in seeking to promote mainstream awareness of systemic and integral thinking in society-at-large. This paper presents evolutionary guidance media, a new model for media arising from evolutionary perspectives including systems science, humanistic, transpersonal and integral studies designed to promote planetary consciousness and give rise to an ecological–spiritual–integral mindset. Two key elements of evolutionary guidance media are discussed: a databank containing purposeful data from nine or more dimensions of human activity, and transception, the infusion of cyberception with qualities arising from mutual causality. Specific types of transception are introduced including Gaiaception, Agoraception, and Dharmaception. Organizations and companies already in the process of creating green media, socially responsible media, and spiritual, or transformational media are vanguards of the development of conscious media.
