Variation in Emotion and Cognition Among Fishes

Increasing public concern for the welfare of fish species that human beings use and exploit has highlighted the need for better understanding of the cognitive status of fish and of their ability to experience negative emotions such as pain and fear. Moreover, studying emotion and cognition in fish species broadens our scientific understanding of how emotion and cognition are represented in the central nervous system and what kind of role they play in the organization of behavior. For instance, on a macro neuro-architecture level the brains of fish species look dramatically different from those of mammals, while such a dramatic difference does not (always) occur at the level of emotion- and cognition-related behavior. Here, therefore, we discuss the evidence of emotion and cognition in fish species related to underlying neuro-architecture and the role that emotion and cognition play in the organization of behavior. To do so we use a framework encompassing a number of steps allowing a systematic approach to these issues. Emotion and cognition confer on human and non-human animals the capacity to compliment and/or override immediate reflexes to stimuli and so allow a large degree of flexibility in behavior. Systematic research on behavior that in mammals is indicative of emotion and cognition has been conducted in only a few fish species. The data thus far indicate that in these species brain-behavior relationships are not fundamentally different from those observed in mammals. Furthermore, data from other studies show evidence that behavior patterns related to emotion and cognition vary between fish species as well within fish species, related to sex and life history stage for example. From a welfare perspective, knowledge of such variability will potentially help us to design optimal living conditions for fish species kept by humans.     

Should Future Generations be Content with Plastic Trees and Singing Electronic Birds?

The aim of this paper is to determine whether the present generation should preserve non-human living things (plants, animals and other organisms) for future generations, even if (i) in the future all the contributions these organisms currently make to human survival in decent conditions were performed by adequate technology and (ii) future people's preferences were satisfied by this state of affairs. The paper argues it would be wrong to leave a world without non-human living plants, animals and other organisms to future generations, because such a world would fail to secure one of the conditions of future people’s autonomy, that is, availability of adequate options. Building upon Joseph Raz’s account of autonomy, the paper shows that the presence of non-human living organisms is part of an adequate range of options insofar as, to be adequate, options must meet a test of variety. According to Raz, options pass this test if they enable human agents to exercise a set of physical, affective, imaginative and cognitive capacities humans normally have an innate drive to exercise. The paper discusses empirical findings as well as psychological theories that provide support to the hypothesis that interactions with non-human living organisms enable human beings to develop and exercise these capacities by shaping these capacities in a special way, different from the way interactions with other environments do.     

Occupational Entropy and Mind Indicators for Sustainable Energy Development

Abstract

A concept of occupational entropy is developed and related to the efficient use of mental (cognitive, emotional, and moral) resources and capacities. The corresponding “mind” indicators and pertinent response actions have proven essential for monitoring the state and projecting the behavior changes toward energy sustainability, as well as sustainable development in general.     

Our forestry prospect: the past recycled or a surprise-rich future?

NORMAN MYERS: An honorary visiting fellow at Green College. He is an independent scientist and consultant working in environment and development.Like most other environmental and economic sectors, forestry worldwide looks set to encounter a growing number of surprises in the sense of major divergencies from established trends. These surprises will be largely environmental or economic or both at once. Unless we do a better job of identifying them ahead of time, these surprises will often be of a scale to overwhelm our anticipatory and preventive capacities. Indeed and as this paper demonstrates, the most likely as well as the most taxing forestry problems of the future will often be the ones we have scarcely thought of. Fortunately, the same applies to forestry opportunities. In these circumstances, there is a premium on not only supplying answers to recognized questions but on raising entirely new questions.     

Exploring Homeowner Diffusion of Yard Care Knowledge as One Step Toward Improving Urban Ecosystems

Urban ecosystems are increasingly influenced by residential yard care decisions. This had led researchers to focus on homeowner education programs when it comes to yard care. Typically, the success of programs designed to influence yard care is based on whether the target subject changes his or her behavior in a more environmentally conscious manner. This threshold, however, fails to consider if individuals share this information with their friends and neighbors, thus having a possible spillover effect. In this paper, we focus on the transmission of new lawn management information among neighbors and consider (1) if individuals discuss information they learned in a short-term educational program, (2) what factors are associated with diffusion, (3) what information individuals share, and (4) what barriers to transmission exist. In the Minneapolis–St. Paul metropolitan area, we used data from a mailed survey, group discussions, and mailed information exchanges. Results indicate that best management practices for yards can diffuse through the neighborhood (approximately 34 % shared information with their neighbors in a one-month period). In addition, factors such as (1) attending a group discussion, 2) individual social connectedness, (3) length of home ownership, and (4) the presence of children in the household were found to be positively related to increased sharing of information. Also, for lawns, the content of information shared tended to be about increasing grass height and reducing fertilizer applications. Finally, we find barriers to sharing ideas based on spatial, temporal, or perception factors but overcoming some of these barriers is possible.     

Statutory Local Nature Reserves in the United Kingdom

Local authorities in Great Britain have had the powers to acquire, declare and manage statutory Local Nature Reserves since 1949; these powers were extended to Northern Ireland in 1985. As of March 1997, there are some 564 Local Nature Reserves in England, three in Northern Ireland, 24 in Scotland and 38 in Wales. Local Nature Reserves are important for biodiversity and nature conservation at a local level and can have a special role for local schools. The overall situation in respect of Local Nature Reserves has been recently reviewed by the Urban Forum of the UK Man and the Biosphere Committee. This review will add impetus and purpose to the wide variety of programmesand projects involving Local Nature Reserves. It will add emphasis to their potential not only for nature conservation and environmental education but also for community development.     

The face of the city is its information

What is it in the externally represented face of the city that makes it recognizable and imaginable? What makes some urban elements and artifacts more legible and better remembered than others? Or put more generally: What makes an object an external representation and what makes it better perceived and/or remembered? Our answer to all these questions is “the information they embody and convey”. Some elements, including those that compose the face of the city, are quantitatively and qualitatively more informative than others and are therefore more legible and better perceived and remembered, quantitatively, in terms of Shannon's theory of information (The Mathematical Theory of Communication, University of Illinois Press, Urbana, IL, 1949), and qualitatively in terms of Haken's (Information and Self-organization: a Macroscopic Approach to Complex Systems, Springer, Heidelberg, 1988/2000) notion of semantic information. In this paper, we elaborate on this point of view in three steps: In the first, we introduce Shannonian information and show how it can be used to define the amount of information externally represented in different urban elements. In the second, we show how this is related to processes of grouping and categorization that give meaning to the face of the city and thus form its semantic information. In the third, we discuss implications for cognition in general and for cognitive mapping in particular.

The outlook for oil

Between now and 2000, the demand for oil is expected to be moderate and the supply abundant. Economic growth is almost twice as slow as in 1973 and requires 25–30% less energy per unit of GNP. The demand for oil is therefore growing at a rate of two to three times slower. Meeting the demand for oil between now and 2000 is within the capability of the oil-producing countries, in many cases with modest additional investment. Gas and coal will be very cost competitive in relation to oil and will serve as a break on future explosive price increases.     

Sustainability: A Study of the Level of Ecological Behavior of Postgraduate Students in Brazil

The decline in the supply of natural resources is a cause for concern, especially given continued worldwide population growth. New habits and attitudes toward resource use are slowly being introduced into the everyday lives of persons residing in a number of countries. The term “ecological behavior” refers to acting in favor of the environment, whether these actions are voluntarily or not, or learned or not (Pato & Tamayo, 2006 ). The general objective of this study is to identify the environmental behavior—one of several terms used interchangeably with ecological behavior—of graduate students from a Brazilian federal institution of higher education. We chose this particular group because many of them already act, or will act, as professors. Thus, by virtue of their positions, they will function as opinion leaders who will influence the education of future professionals, establishing a chain through which shared values can gradually change the environmental behavior of society.     

Democracy at its Best? The Consensus Conference in a Cross-national Perspective

Over recent decades, public participation in technology assessment has spread internationally as an attempt to overcome or prevent societal conflicts over controversial technologies. One outcome of this new surge in public consultation initiatives has been the increased use of participatory consensus conferences in a number of countries. Existing evaluations of consensus conferences tend to focus on the modes of organization, as well as the outcomes, both procedural and substantial, of the conferences they examine. Such evaluations seem to rest on the assumption that this type of procedure has universally agreed goals and meanings, and that therefore consensus conferences can readily be interpreted and applied across national boundaries. This article challenges this approach to consensus conferences. The core of the article is a study of national differences in ideas about what constitutes legitimate goals for participatory arrangements. The study looks at three consensus conferences on GMOs, which took place in France, Norway, and Denmark. Drawing on this study, the article discusses the ways in which interpretations of the concept of participation; the value attributed to lay knowledge vs. technical expertise; as well as ideas about the role of the layperson, are all questions that prompt entirely different answers from country to country. Further, the article analyses these national differences within a theoretical framework of notions of democratic legitimacy.     

Phytoremediation of Copper‐Contaminated Soil Using Helianthus annuus,Brassica nigra,and Lycopersicon esculentum Mill.: A Pot Scale Study

Phytoremediation is an eco‐friendly and cost‐effective technology that uses plants to extract contaminants from the environment or to decrease contaminant toxicity. This article documents a study not only of the effectiveness of copper uptake by Heliantus annuus (common sunflower), Brassica nigra (black mustard), and Lycoperscion esculentum Mill. (a tomato species), but of where, within these plant species, the copper is accumulated—in the roots or in the shoots. This is vital information, for if these particular plants accumulate copper primarily in their roots, then their edible portions will likely be safe to eat, while if they accumulate the copper in their shoots, their harvestable portions would be harmful to living beings.     

Passive treatment of acid mine drainage with high metal concentrations using dispersed alkaline substrate

Passive treatment systems based on the dissolution of coarse calcite grains are widely used to remediate acid mine drainage (AMD). Unfortunately, they tolerate only low metal concentrations or acidity loads, because they are prone to passivation (loss of reactivity due to coating) and/or clogging (loss of permeability) by precipitates. To overcome these problems, a dispersed alkaline substrate (DAS) composed of a fine-grained alkaline reagent (calcite sand) mixed with a coarse inert matrix (wood chips) was developed. The small grains provide a large reactive surface and dissolve almost completely before the growing layer of precipitates passivates the substrate, whereas the dispersion of nuclei for precipitation on the inert surfaces retards clogging. Chemical and hydraulic performance of DAS was investigated in two laboratory columns fed at different flow rates with natural AMD of pH 2.3 to 3.5 and inflow net acidity 1350 to 2300 mg/L as CaCO(3). The DAS columns removed 900 to 1600 mg/L net acidity, 3 to 4.5 times more than conventional passive treatment systems. Regardless of the flow rate employed, Al, Fe(III), Cu, and Pb were virtually eliminated. Minor Zn, Ni, and Cd were removed at low flow rates. High acidity removal is possible because these metals accumulate intentionally in DAS, and their precipitation promotes further calcite dissolution. During 15 mo, DAS operated without clogging at 120 g acidity/m(2).d, four times the loading rate recommended for conventional passive systems; DAS may therefore be capable of treating AMD at sites where influent chemistry precludes the use of other passive systems.     

The greening of Chicago: environmental leaders and organisational learning in the transition toward a sustainable metropolitan region

Urban sustainability literature calls for new governance relations to support green urban agendas. Privileging non-hierarchical relations, this literature fails to address the means by which organisations create these capacities. The author interviewed public, private and community environmental leaders in metropolitan Chicago regarding their disposition toward creating boundary spanning organisations (BSOs) in addressing the City's Environmental Action Agenda. Their responses reflect engaged efforts to enhance cross-boundary sharing of information, resources, and power. However, they also reflect the decisive role of central authority in initiating this process. These findings suggest the complexity of urban governance in transitions toward sustainability and the opportunities they provide to explore the implications of on-the-ground practice.     

Does Fish Welfare Matter? On the Moral Relevance of Agency

To determine whether fish welfare matters morally, we need to know what characteristics or capacities beings need to have in order to be morally considerable, and whether fish have such characteristics. In this paper I discuss a group of theories, Kantian practical reasoning theories, in which agency (or practical rationality) is traditionally thought to be a necessary condition for moral considerability. An individual must have quite sophisticated capacities to be a (moral) agent in such theories: she must be able to act on rational principles. It seems unlikely that nonhuman animals such as fish have such capacities. I argue, however, that on the basis of certain Kantian arguments, moral agents have reason to accept duties to nonrational animals if they are agents in a much less demanding sense: if they are motivated to pursue the objects of their desires. If fish have this capacity, their welfare matters morally.     

Friends of the land and the rise of environmentalism, 1940–1954

The rise of the postwar environmental movement is rooted in the development of ecological consciousness within intellectual circles as well as the general public. Though many commentators cite the 1960s as the focal point of the new environmentalism, the ecological ethic had actually evolved by the 1930s in the writings and speeches of both scientists and public commentators. Agricultural conservationists led the way in broadcasting the message of ecology. Friends of the Land, an agriculturally-oriented conservation organization formed in 1940 and active through the 1950s, is an interesting example of how the agricultural community was an integral component in the rise of environmentalism. While Friends of the Land flourished only for a brief period, its goals and the ideas that the group represented illustrate how the ecological ethic was burgeoning by the early-1950s. Furthermore, the history of Friends of the Land is an important chapter in the ongoing quest for ecological agriculture and societal permanence.     

The role of atmospheric transformations in determining environmental impacts of carbonaceous nanoparticles

In studies that have explored the potential environmental impacts of manufactured nanomaterials, the atmosphere has largely been viewed as an inert setting that acts merely as a route for inhalation exposure. Manufactured nanomaterials will enter the atmosphere during production, use, and disposal, and rather than simply being transported, airborne nanoparticles are in fact subject to physical and chemical transformations that could modify their fate, transport, bioavailability, and toxicity once they deposit to aqueous and terrestrial ecosystems. The objective of this paper is to review the factors affecting carbonaceous nanomaterials' behavior in the environment and to show that atmospheric transformations, often overlooked, have the potential to alter nanoparticles' physical and chemical properties and thus influence their environmental fate and impact. Atmospheric processing of naturally occurring and incidental nanoparticles takes place through coagulation, condensation, and oxidation; these phenomena are expected to affect manufactured nanoparticles as well. It is likely that carbonaceous nanomaterials in the atmosphere will be oxidized, effectively functionalizing them. By influencing size, shape, and surface chemistry, atmospheric transformations have the potential to affect a variety of nanoparticle-environment interactions, including solubility, interaction with natural surfactants, deposition to porous media, and ecotoxicity. Potential directions for future research are suggested to address the current lack of information surrounding atmospheric transformations of engineered nanomaterials.
