Interactions Among the Copper Species and Forms in Sea Water/Sediments and Copper Bioaccumulation in Oysters

Abstract

Earlier papers indicated that the first incident of green discoloration in oysters (Crassostrea gigas) and the mass mortality observed in 1986 along the Taiwan Erhjin Chi coastal area were caused by the higher contents of total copper and copper species (mainly bioavailable and free ion) in sea water. the copper in sea water would be sorbed by suspended matter and transferred to sediments, and the copper in the sediments would also be desorbed to sea water. Processes of copper adsorption and desorption are the major factors influencing the contents of total copper and copper species in sea water and sediments. in this study, the Erhjin Chi sediments were mixed with sea water by a shaker technique. When the mixture was shaken for one hour, analogous to tidal mixing in estuaries, only copper desorption from sediments was observed. If the shaking time is increased for more than 3 hours, the copper released from the sediments was resorbed to the remaining solid phases. the higher the contents of mud (91.71%) and total copper (701 mg kg^?1) in sediments, the higher the copper desorption rate (1.86 ppm hr^?1) and copper adsorption rate (0.50 ppm hr^?1) were observed. in sediments containing lower mud (0.80%) and lower copper (43.5 mg kg^?1), the copper desorption and adsorption rates were 0.83 ppm hr^?1 and 0.22 ppm hr^?1, respectively. the interactions among the total copper and copper species in sea water and sediments, chemical and ecological parameters, and copper bioaccumulation in oysters in the Erhjin Chi estuarine and coastal area are also discussed.

A Phenomenological Perspective on Ethical Duty in Environmental Communication

This article examines the framing of environmental risks and natural disasters in factual entertainment television programs of the early 2000s, a hybrid form combining techniques from documentary with techniques such as dramatic reconstructions and computer-generated imagery from entertainment genres. Using qualitative frame analysis, it examines a range of factual entertainment television programs' framing of environmental risk and natural disasters in terms of their attitudes, representation of human participants and visual composition. The article considers the similarities and differences in the framing of natural disasters as factual entertainment compared to the framing of natural disasters in news, documentary and fiction film. It argues that such programs offer representational frames both consonant with and distinct from other media and concludes that they problematically offer a predominantly fatalistic response to environmental risk, constructing natural disasters as voyeuristic spectacles for vicarious entertainment.     

Introduction: General versus specific measures and the special case of core self‐evaluations

This paper introduces a Journal of Organizational Behavior point/counterpoint exchange (this issue) that focuses on the appropriate level of aggregation primarily in the assessment of personality in general and core self‐evaluations (CSE) in particular. Gilad Chen reviews arguments for and against the higher‐order construct of CSE, offering a number of recommendations for strengthening it. Timothy Judge and John Kammeyer‐Mueller offer a defense of CSE, and then extend the discussion to the measurement of other constructs beyond the personality domain. Together these two papers provide important insights about the appropriate level of aggregation of individual measures, and situations in which higher‐order versus lower‐order measures might be preferred.

国内外旅游系统模型研究综述

从系统论角度来考虑。人类的旅游活动是一个系统。旅游系统是备种旅游事象的集合体。是通过旅游者的旅游活动使备组成要素相互联系、相互作用构成的一个有机整体．它具有实现旅游价值的整体功能。在分析和阐释旅游系统特征的基础上，以时间为序列对国内外学者提出的旅游系统模型进行了介绍评述和总结．指出系统论的观点不仅为旅游资源的开发提供了认识论基础；同时又为旅游规划和开发提供了方法论基础，并提出，对具有环境观和复杂性特点的旅游地理系统的研究将成为未来旅游科学的重要研究方向。旅游系统模型的建立将为旅游（业）的研究提供现实的理论基础。

Environmental disasters,migration and displacement. Insights and developments from L’Aquila's case

This paper analyses the environmentally-induced migration and displacement resulting from L’Aquila's earthquake of 2009. After a general critical overview of the social science literature on this topic, the main changes in the migration system are analysed looking at the roots and trajectories of the forced human displacement that followed the earthquake, and reflecting on the challenges related to post-earthquake demographic movements and post-disaster resettlement. Through the analysis of the pre disaster (2002–2008) and recovery period (2009–2013) data, this paper offers a general model of how environmental disaster might affect migration and displacement and suggests the main challenges related to the post-disaster governance. Relying on ISTAT data on internal migration in Italy this paper argues that the post-seismic recovery period is characterized by a strong increase of out-flows from L’Aquila to other provinces, within the Abruzzo region and outside it, in particular toward the closest regions (Latium, Campania).
