The following research applies a socio-technical approach to an original study of the role of BRE environmental assessment method (BREEAM) in sustainable building practice. The primary objective is to gain insight into what facilitates and what weakens professional associations to implement a sustainability agenda in a building project. It focuses on understanding different sets of meaning which underlie engagement with BREEAM and how BREEAM is actioned. To do this, the research framework draws on social network analysis. However, this research does not consider that sustainable building is merely an outcome of planned action. Instead, sustainable building is seen to involve processes of engagement amongst different groups, technologies, materials and methods. Therefore, the conceptual framework adopted incorporates consideration of the materiality of sustainable building engagements, highlighting the relations between actors. Interviews with project professionals involved in a case study of a BREEAM Outstanding development provide the empirical basis for this work. This research will be of interest to scholars interested in socio-technical approaches to building development, environmental building assessment methods and sustainable building.  相似文献

The client relationships and tacit knowledge of professionals are professional service firms' (PSFs') major value creating resources producing challenges in generating post‐merger and acquisition value and risks of reducing the productivity or losing key professionals and their clients. The recent emergence of publicly owned PSFs and rapid growth through consolidating smaller privately owned firms potentially increases this risk by integrating small firms and their professionals into large public companies that may be governed very differently. This study explores post‐acquisition integration processes: professional behaviours and associated performance implications in two highly acquisitive publicly owned accounting companies. In one company, the integration process was rapid and heavily directed by senior management, while in the second company, integration was more gradual, initially undirected but then facilitated by senior management. The findings suggest that integration processes can impact the behaviour of professionals and acquiring firm performance. This research contributes to the understanding of post‐acquisition integration processes in PSFs and decision‐making and professional behaviour in recently emerged publicly owned PSFs. The study contributes to knowledge‐based theory by identifying factors that can affect the decision authority of executives and how organisational behaviour can constrain the implementation of executive integration decisions.

Non‐native plants have invaded nearly all ecosystems and represent a major component of global ecological change. Plant invasions frequently change the composition and structure of vegetation communities, which can alter animal communities and ecosystem processes. We reviewed 87 articles published in the peer‐reviewed literature to evaluate responses of arthropod communities and functional groups to non‐native invasive plants. Total abundance of arthropods decreased in 62% of studies and increased in 15%. Taxonomic richness decreased in 48% of studies and increased in 13%. Herbivorous arthropods decreased in response to plant invasions in 48% of studies and increased in 17%, likely due to direct effects of decreased plant diversity. Predaceous arthropods decreased in response to invasive plants in 44% of studies, which may reflect indirect effects due to reductions in prey. Twenty‐two percent of studies documented increases in predators, which may reflect changes in vegetation structure that improved mobility, survival, or web‐building for these species. Detritivores increased in 67% of studies, likely in response to increased litter and decaying vegetation; no studies documented decreased abundance in this functional group. Although many researchers have examined effects of plant invasions on arthropods, sizeable information gaps remain, specifically regarding how invasive plants influence habitat and dietary requirements. Beyond this, the ability to predict changes in arthropod populations and communities associated with plant invasions could be improved by adopting a more functional and mechanistic approach. Understanding responses of arthropods to invasive plants will critically inform conservation of virtually all biodiversity and ecological processes because so many organisms depend on arthropods as prey or for their functional roles, including pollination, seed dispersal, and decomposition. Given their short generation times and ability to respond rapidly to ecological change, arthropods may be ideal targets for restoration and conservation activities.

Around 130 publications reporting studies on radionuclide transfer to freshwater biota species conducted in the former USSR were reviewed to provide the concentration ratio values. None of these studies were available up to now in the English language reviews or publications. The values derived have been compared with the CR values used for freshwater systems in the International reviews. For some radionuclides reviewed in this paper, the data are in good agreement with the mean CR values presented earlier, however for some of them, in particular, for 241Am (bivalve molluscs, gastropods and pelagic fish), 60Co (gastropods, benthic fish and insect larvae), 90Sr and 137Cs (benthic fish and zooplankton), the mean values given here are substantially different from those presented earlier. The data reported in this paper for thirty five radionuclides and eleven groups of freshwater species markedly improve the extent of available data for evaluation of radiation impact on freshwater species.  相似文献

文化对机组资源管理的影响   总被引:1,自引:0,他引:1  
针对国内民航机组资源管理(CRM)及训练中忽视文化的作用和影响的现状,在调研和分析国外CRM与文化影响的基础上,笔者结合国内民航的运行特点,总结、分析了民族文化、组织文化,以及职业文化对机组协作与配合,CRM训练等方面的积极与消极影响,提出中国民航应根据自身的文化特点调整CRM训练的内容和实施方式,并应从3个层面采取措施来提高CRM及其训练的效果,即航空公司CRM训练的设计、实施与评估;飞机制造商在进行驾驶舱人-机界面设计,以及政府部门在对航空器进行适航审定时,应充分识别不同文化的差异、在强化各种文化类型积极影响的同时,努力降低或消除其消极影响。  相似文献

This study reviews research on cash and voucher assistance (CVA) by applying a humanitarian supply chain management perspective. A systematic literature review was conducted to identify, analyse, and synthesise past academic research. The content, context, and process framework was used to structure the content analysis. The findings reveal that the outcomes of CVA programmes are dependent on critical context-specific variables that influence feasibility and operability. Humanitarian actors must consider factors that are external (the nature of disaster, politics, economy, and infrastructure) and internal (local market availability and accessibility, supplier/donor interest, supplier/vendor selection and contracting, and beneficiary preference) to the supply chain. The delivery process is influenced by them, impacting on programme responsiveness and cost-efficiency. The results provide insights that humanitarian practitioners can utilise to reconsider their supply chain strategies when deciding on the selection and implementation of CVA programmes. Potential literature gaps are identified, and recommendations for further research are provided.  相似文献
