Merging Duke Energy and Progress Energy: Online Public Discourse,Post-Fukushima Reactions,and the Absence of Environmental Communication

This article examines online discourse in 2011 surrounding the proposed Duke Energy and Progress Energy merger in the Carolinas. It explores how issues pertaining to the merger, including constructing new nuclear plants, are discussed in media coverage and by citizens using social media. Overall, we find that the merger discourse focuses on economic concerns rather than the environmental concerns we had anticipated. However, post-Fukushima discourse appears to have become more inclusive of environmental concerns. We conclude that environmental discussions and efforts are likely to be globally informed andlocally situated, discussing the implications for environmental communication research exploring online discourses, specifically through social media. Future research must address how to locate and delineate constellations of locally situated discourse to provide a clearer picture of environmentally focused social media communication.     

Bridging the gaps for global sustainable development: A quantitative analysis

Global human progress occurs in a complex web of interactions between society, technology and the environment as driven by governance and infrastructure management capacity among nations. In our globalizing world, this complex web of interactions over the last 200 years has resulted in the chronic widening of economic and political gaps between the haves and the have-nots with consequential global cultural and ecosystem challenges. At the bottom of these challenges is the issue of resource limitations on our finite planet with increasing population. The problem is further compounded by pleasure-driven and poverty-driven ecological depletion and pollution by the haves and the have-nots respectively. These challenges are explored in this paper as global sustainable development (SD) quantitatively; in order to assess the gaps that need to be bridged.Although there has been significant rhetoric on SD with very many qualitative definitions offered, very few quantitative definitions of SD exist. The few that do exist tend to measure SD in terms of social, energy, economic and environmental dimensions. In our research, we used several human survival, development, and progress variables to create an aggregate SD parameter that describes the capacity of nations in three dimensions: social sustainability, environmental sustainability and technological sustainability. Using our proposed quantitative definition of SD and data from relatively reputable secondary sources, 132 nations were ranked and compared.Our comparisons indicate a global hierarchy of needs among nations similar to Maslow's at the individual level. As in Maslow's hierarchy of needs, nations that are struggling to survive are less concerned with environmental sustainability than advanced and stable nations. Nations such as the United States, Canada, Finland, Norway and others have higher SD capacity, and thus, are higher on their hierarchy of needs than nations such as Nigeria, Vietnam, Mexico and other developing nations. To bridge such gaps, we suggest that global public policy for local to global governance and infrastructure management may be necessary. Such global public policy requires holistic development strategies in contrast to the very simplistic north–south, developed–developing nations dichotomies.     

Neighborhood Conditions and Helping Behavior in Late Life

The purpose of this study is to develop and test a latent variable model that explores the ways in which social structural factors influence the amount of social support that older adults provide to their social network members. Neighborhood conditions play a key role in this conceptual scheme. The findings provide support for the following conceptual linkages: (1) low parental education is associated with low respondent education; (2) older people with less education encounter more economic difficulty; (3) greater financial problems are associated with living in a rundown neighborhood; (4) older individuals who live in dilapidated neighborhoods are more hostile; and (5) older adults who are hostile are less likely to provide social support to their social network members. Research indicates that helping others is a key to successful aging. Ways must be found to help economically disadvantaged elders provide support to their social network members.     

Analysis of livelihood security: a case study in the Kali-Khola watershed of Nepal

This paper examines household livelihoods in highland and lowland communities of the Kali-Khola agricultural watershed in western Nepal on the basis of economic, ecological and social security indicators. Significant differences were found in soil fertility status, pests and diseases management, risk and uncertainties, use of agrochemicals and access to social services. No remarkable variations were found in crop diversification, annual agricultural income and food sufficiency. However, uncertainty and risk in agricultural production is relatively low in highland communities. The findings reveal that agriculture production alone is not a viable livelihood option for agricultural watershed communities in Nepal. The households growing crops with hired labour have relatively sustainable livelihoods in Nepal's agricultural watersheds. Insufficient agricultural land, insufficient working manpower within a family, and lack of access to ecological agricultural services are prime factors in being livelihood insecure in agricultural watershed communities. Therefore, long-term policies and plans need to be developed for the empowerment of local farmers and to support rural livelihoods with adaptable and flexible income-generating strategies, resilient resource management institutions and enhancement of knowledge, skills and social capital.     

Social Capital and Fisheries Management: The Case of Chilika Lake in India

This article shows how social capital impacts fisheries management at the local level in Chilika Lake, located in the state of Orissa in India. In Chilika, the different fishing groups established norms and “rules of the game” including, but not limited to, spatial limits that determine who can fish and in what areas, temporal restrictions about when and for how long people may fish, gear constraints about what harvesting gear may be used by each group, and physical controls on size and other characteristics of fish that may be harvested. A survey of the members of fishing groups has shown that the bonding social capital is strong within the Chilika fishing groups. Bonding and bridging social capital keeps the fishers together in times of resource scarcity, checks violations of community rules and sanctions, and strengthens the community fisheries management. In contrast, linking social capital in Chilika appears to be weak, as is evident from the lack of trust in external agencies, seeking the help of formal institutions for legal support, and increasing conflicts. Trust and cooperation among fishers is crucial in helping to build the social capital. A social capital perspective on fisheries governance suggests that there should be a rethinking of priorities and funding mechanisms, from “top-down” fisheries management towards “co-management” with a focus on engendering rights and responsibilities for fishers and their communities.

The failure of success in fisheries management

Law of the Sea negotiations and The Fishery Conservation and Management Act of 1976 create new options in fisheries management. Historical analysis of two major management programs in the United States of America, Columbia River chinook salmon (Oncorhynchus tshawytscha) and Pacific halibut (Hippoglossus stenolepis), shows two unresolved management problems. One is the innovativeness of fishermen in seeking ways to improve their harvests. The other is changing social priorities that are largely unpredictable and outside the control of fisheries managers. A method for analysis of patterning associated with management goals is illustrated. Since the general management goals are harvest improvement and more predictability, measures are used which show the adequacy of fit and reduction in variability between actual and predicted management outcomes.     

From farming families to scavengers: a case study in the outskirts of Belém in the state of Pará

 In the middle of the 1970s, the introduction of large industrial and agricultural projects in Brazilian Amazonia created a situation of violence and loss of land used by farming families. In this context, the process of migration to the metropolitan region of Belém, which is principally in the interior of the state of Pará, was intensified. Excluded by the formal labor market, these families started to collect disposed material as scavengers. The material collected is found in landfills, streets, and open dumping areas. The main purpose of this research is to understand the social and environmental relations inherent in collection and recycling activities in the Amazon Region.

Defining response capacity to enhance climate change policy

Climate change adaptation and mitigation decisions made by governments are usually taken in different policy domains. At the individual level however, adaptation and mitigation activities are undertaken together as part of the management of risk and resources. We propose that a useful starting point to develop a national climate policy is to understand what societal response might mean in practice. First we frame the set of responses at the national policy level as a trade off between investment in the development and diffusion of new technology, and investment in encouraging and enabling society to change its behaviour and or adopt the new technology. We argue that these are the pertinent trade-offs, rather than those usually posited between climate change mitigation and adaptation. The preference for a policy response that focuses more on technological innovation rather than one that focuses on changing social behaviour will be influenced by the capacity of different societies to change their greenhouse gas emissions; by perceived vulnerability to climate impacts; and by capacity to modify social behaviour and physical environment. Starting with this complete vision of response options should enable policy makers to re-evaluate the risk environment and the set of response options available to them. From here, policy makers should consider who is responsible for making climate response decisions and when actions should be taken. Institutional arrangements dictate social and political acceptability of different policies, they structure worldviews, and they determine the provision of resources for investment in technological innovation and social change. The importance of focussing on the timing of the response is emphasised to maximise the potential for adjustments through social learning and institutional change at different policy scales. We argue that the ability to respond to climate change is both enabled and constrained by social and technological conditions. The ability of society to respond to climate change and the need for technological change for both decarbonisation and for dealing with surprise in general, are central to concepts of sustainable development.     

Effects of colony size and stage of development on defense response by the swarm-founding wasp<Emphasis Type="Italic"> Polybia occidentalis</Emphasis>

In social insects the level of defensive effort generally increases with colony size, but the effects of the size of the defending adult population and the size of the brood population being defended have not been separated. We used pre-emergence-stage colonies of the swarm-founding wasp, Polybia occidentalis, to distinguish the effects of these two parameters on the intensity of colony defense. We elicited defensive behavior by using both mechanical (taps) and chemical (alarm-pheromone-containing venom) stimuli, and scored the responses as the number of attacks on a standard target. The intensity of defense increased linearly throughout the colony's first 25 days of development, despite the decrease in absolute numbers of adults during the same period. That is, the per capita attack rate increased strongly during this period, leading us to conclude that the intensity of defense is a function of the colony's investment in brood and not of the number of defending adults. We provide evidence that the increase is attributable neither to sensitization due to frequent disturbance, nor to the aging of the adult wasps. We further show that defensive effort on a per capita basis decreased with increasing size across colonies, whether colony size was measured as number of adults or as investment in brood. This pattern suggests that the cost-benefit relationship of defending the colony changes with colony size.Communicated by R.F.A. Moritz
