The Argument from Existence,Blood-Sports,and ‘Sport-Slaves’

The argument from existence is often used as an attempted justification for our use of animals in commercial practices, and is often put forward by lay-persons and philosophers alike. This paper provides an analysis of the argument from existence primarily within the context of blood-sports (applying the argument to the example of game-birding), and in doing so addresses interesting and related issues concerning the distinction between having a life and living, or worthwhile life and mere existence, as well as issues surrounding our responsibilities to prospective and actual beings. However, my analysis of the argument will go beyond the animal ethics context; it is important that it does so in order to reveal the troublesome implications of the argument and to highlight the sorts of unethical practices it supports. In particular, in applying the argument to a relevant example concerning human beings, I will discuss how the argument from existence could be used to justify the ownership of slaves who were reared for slavery. My objective is to show just how problematic the argument from existence is, with the aim of laying the argument to rest once and for all.     

Value Pluralism And Coherentist Justification of Ethical Advice

Liberal societies are characterized by respect for a fundamental value pluralism; i.e., respect for individuals’ rights to live by their own conception of the good. Still, the state must make decisions that privilege some values at the cost of others. When public ethics committees give substantial ethical advice on policy related issues, it is therefore important that this advice is well justified. The use of explicit tools for ethical assessment can contribute to justifying advice. In this article, I will discuss one approach to ethical assessment, the ethical matrix method. This method is a variant of intuitionist balancing. Intuitionism is characterized by stressing the existence of several (at least two) fundamental prima facie moral principles, between which there is no given rank order. For some intuitionist approaches, coherentism has been proposed as a model of justification. This article will discuss justification of ethical advice and evaluate the appropriateness of coherentism as a justificatory approach to intuitionist tools.     

Food Law,Ethics, and Food Safety Regulation: Roles,Justifications, and Expected Limits

Recent food emergencies throughout the world have raised some serious ethical and legal concerns for nations and health organizations. While the legal regulations addressing food risks and foodborne illnesses are considerably varied and variously effective, less is known about the ethical treatment of the subject. The purpose of this article is to discuss the roles, justifications, and limits of ethics of food safety as part of public health ethics and to argue for the development of this timely and emergent field of ethics. The article is divided into three parts. After a short introduction on public health ethics, all levels of food safety processes are described and the role that ethics play in each of these levels is then analyzed. In the second part, different models describing the function of food law are examined. The relationship between these models and the role of ethics of food safety is assessed and discussed in the final part, leading to some relevant comments on the limits of the role and effect of ethics of food safety.     

The Problem of the Question About Animal Ethics: Discussion with Mark Coeckelbergh and David Gunkel

In this article I discuss the thesis put forward by David Gunkel and Mark Coeckelbergh in their essay Facing Animals: A Relational, Other-Oriented Approach to Moral Standing. The authors believe that the question about the status of animals needs to be reconsidered. In their opinion, traditional attempts to justify the practice of ascribing rights to animals have been based on the search for what is common to animals and people. This popular conviction rests on the intuition according to which we tend to treat better those beings that are closer to us and resemble man in one way or the other. The attempts to ascribe a special status to animals are therefore based on the question “What properties does the animal have?”. However, the question is not well formulated because it leads to a number of ontological and epistemological problems. The question should rather be “What are the conditions under which an entity becomes a moral subject?”. Whilst fully subscribing to the suggestion, I cannot agree to the way the question is understood by both authors. I will demonstrate that the question opens up a transcendental dimension of reflections and may provide a clear justification of the need to engage in animal ethics. To do so, I will separate the easy and hard problems of animal ethics and use a different approach from the one suggested by Gunkel and Coeckelbergh to demonstrate how the need to pursue animal ethics may be justified.     

Species Extinction and the Vice of Thoughtlessness: The Importance of Spiritual Exercises for Learning Virtue

In this paper, I present a sample spiritual exercise—a contemporary form of the written practice that ancient philosophers used to shape their characters. The exercise, which develops the ancient practice of the examination of conscience, is on the sixth mass extinction and seeks to understand why the extinction appears as a moral wrong. It concludes by finding a vice in the moral character of the author and the author’s society. From a methodological standpoint, the purpose of spiritual exercises is to create a habit of thoughtfulness in the writer, and by way of teaching, to suggest one to the reader. Such a habit is important, at least, because virtue is a habit. In other words, there can be no learning of virtue itself without habituation into it. Accordingly, I frame the sample spiritual exercise with a deliberately controversial objection to contemporary academic virtue ethics and with a justification for why the spiritual exercise is important for taking virtue ethically. And I end the paper with some further remarks explaining the form of the exercise and its relevance to doing philosophy. In this way, the paper makes and illustrates a methodological point about virtue ethics based on a meta-ethical assumption about virtue as a habit, and it does this by focusing on a pressing environmental problem in the twenty-first century.     

Is there a sustainability canon?

This paper identifies one possible set of appropriate disciplinary content for undergraduate programs in sustainability, based on a survey instrument employed at two international sustainability events in 2005. Undertaken to supplement the focus in the sustainability education literature on generic skills and pedagogical method via case-based or broadly conceptual work, it seeks to assist curriculum developers with planning disciplinary content. Findings indicate that a sustainability canon of sorts exists. A surprising amount of agreement existed from the two different specialist groups about core concepts, notably in ecology and—less unanimously—policy, economics and ethics. Studies about society were preferred as elective content. A 10-subject core was nominated, suggesting the need for broad foundational underpinnings.     

Past and future sustainability of water policies in Europe

The article contributes to a discussion on two global issues on water: water resources management, and water supply and sanitation. Focusing on Europe, it traces the legal roots of current systems in history: as a resource, water is considered as a common property, rather than a market good; while as a public service it is usually a commodity. Public water supply and sanitation technologies and engineering have developed under three main paradigms: quantitative and civil engineering; qualitative and chemical/sanitary engineering (both on the supply side); and the most recent one, environmental engineering and integrated management (on the demand side). The cost of public drinking water is due to rise sharply in view of the two‐fold financial challenge of replacing an ageing infrastructure and keeping up with ever‐rising environmental and sanitary quality standards. Who will pay? Government subsidies, or water users? The author suggests that apparent successes with privatisation may have relied heavily on hidden government subsidies and/or the healthy state of previously installed water infrastructure: past government subsidies are still felt for as long as the lifetime of the infrastructure. The article stresses the importance of public participation and decentralized local management of water and sanitation services. Informing and involving users in water management decisions is seen as an integral part of the ‘ethics’ side of the crucial three E's (economics, environment, ethics). The article strongly argues for municipal provision of water services, and hopes that lessons learnt and solutions found in the European experience may serve water services management efforts in other regions of the world.     

Errant corporations, diffuse responsibilities, and the environment: ethical issues in the Orica case study

The papers in this volume deal with various aspects of the HCB legacy at the Orica plant at Botany. Whether explicitly or implicitly, they are concerned with questions of ethics; with the just distribution of burdens and benefits; with just processes for disposing of dangerous industrial waste; and with a just custodianship of the Botany environment. These ethical issues illustrate the difficulty of securing corporate accountability, and the elusiveness of responsibility within organisations. This paper reflects on some of the issues for ethics raised by the Orica case and their significance for corporate ethics.     

Multi-hazard, multi-infrastructure, economic scenario analysis

Over the past 10 years, the National Infrastructure Simulation and Analysis Center (NISAC) has conducted over 150 detailed multi-hazard, multi-infrastructure scenario analyses of a wide range of man-made and natural disasters. Using a model-based implementation of the Department of Homeland Security risk management framework, NISAC analyzes scenarios ranging from extreme-event situational awareness to long-term strategic policy for improved homeland security and resilience to these events. This article describes the essential elements of the NISAC scenario analysis process, the toolkit of subject-matter expertise and models used, with a particular focus on the economics component. An example set of Hurricane Katrina economic-analysis results is used to illustrate basic elements of NISAC economics scenario analysis.

The Epistemic Demands of Environmental Virtue

To lead an environmentally virtuous life requires information—about morality, environmental issues, the impacts of our actions and commitments, our options for alternatives, and so on. On the other hand, we are finite beings with limited time and resources. We cannot feasibly investigate all of our options, and all environmental issues (let alone moral issues, more broadly). In this paper I attempt to provide initial steps towards addressing the epistemic demands of environmental virtue. In the first half of the paper I provide rules of thumb with respect to (1) how to prioritize our investigations into various issues, and (2) what kinds of information we should seek with respect to these issues, and the levels of epistemic justification we ought to attain. In the second half of the paper, I turn to a modified virtue ethics, appealing to the attitudes of virtuous ideal observers to provide characterizations of morally justified and morally non-culpable actions. I then apply these latter concepts in assessing agents, their actions and projects (with respect to environmental virtue), in light of their investigative efforts, and given their particular circumstances.

Risks Associated with Genetic Modification: – An Annotated Bibliography of Peer Reviewed Natural Science Publications

We present an annotated bibliography of peer reviewed scientific research highlighting the human health, animal welfare, and environmental risks associated with genetic modification. Risks associated with the expression of the transgenic material include concerns over resistance and non-target effects of crops expressing Bt toxins, consequences of herbicide use associated with genetically modified herbicide-tolerant plants, and transfer of gene expression from genetically modified crops through vertical and horizontal gene transfer. These risks are not connected to the technique of genetic modification as such, but would be present for any conventionally produced crops with the same heritable traits. In contrast, other risks are a direct consequence of the method used in gene manipulation. These come about because of the unstable nature of the transgene and vectors used to insert it, and because of unpredictable interactions between the transgene and the host genome. The debate over the release of genetically modified organisms is not merely a scientific one; it encompasses economics, law, ethics, and policy. Any discussion on these levels does, however, need to be informed by sound science. We hope that the scientific references provided here will provide a useful starting point for further debate.     

ECONOMICS AND FEDERAL WATER PROJECTS1

While the science of economics is widely used in Federal water resource development projects, the usual procedure of applying an analytical discipline to arrive at a conclusion is reversed. The “answer” is usually provided ahead of time and economics is assigned the task of justifying the preconceived conclusion. This leads to a series of mitigatory effects in which economics as a science is not allowed to freely function. This article attempts to illustrate some of these “unusual” uses of economics in Federal water projects and note the “answers” we would logically expect from the economic discipline. Even though the theory of economics is often subverted, there are positive aspects to the role of economics in evaluating Federal water projects.     

The U.S. Flood Control Program at 75: Environmental Issues1

Black, Peter E., 2012. The U.S. Flood Control Program at 75: Environmental Issues. Journal of the American Water Resources Association (JAWRA) 48(2): 244‐255. DOI: 10.1111/j.1752‐1688.2011.00609.x Abstract: Recent, recurring, and increased magnitude floods adversely challenge long‐held and erroneous concepts of flood control. This article focuses on the environmental issues with comprehensively reviewed essentials of the United States (U.S.) riverine Flood Control Program, including news reports, scientific articles, books, and landmark treatises. For the past three‐quarters of a century, U.S. floods have continued (and will continue) to occur, causing increasing property damage with growing fiscal loss. Reasons include inattention to fundamental principles of physics, hydrology, and ecology. There are also important challenges involving environmental policy, economics, and common sense. Measures afforded by the existing program encourage and enable investment in floodplains while violating a variety of natural principles that make the situation worse. This detailed review includes the questionable (actually untrue) justification in the document‐setting policy for the 1936 Omnibus Flood Control Act. The well‐documented evidence is overwhelming. An alternative approach is presented that would enable and celebrate natural floods, managing their ecological and hydrological values, and not attempting to control them.     

Food Safety, Quality, and Ethics – A Post-normal Perspective

I argue that the issues of foodquality, in the most general sense includingpurity, safety, and ethics, can no longer beresolved through ``normal' science andregulation. The reliance on reductionistscience as the basis for policy andimplementation has shown itself to beinadequate. I use several borderline examplesbetween drugs and foods, particularly coffeeand sucrose, to show that ``quality' is now acomplex attribute. For in those cases thesubstance is either a pure drug, or a bad foodwith drug-like properties; both are marketed asif they were foods. An example of theinadequacy of old ways of thinking is obesity,whose causes are as yet outside the purview ofmedicine, while its effects constitute anepidemic disease. The new drug/food syndromeneeds a new sort of science, what we call``post-normal.' This is inquiry at the contestedinterfaces of science and policy; typically itdeals with issues where facts are uncertain,values in dispute, stakes high, and decisionsurgent. With the perspective of post-normalscience, we can better understand some keyissues. We see that ``safety' is different from``risk,' being pragmatic, moral, and recursive.Also, we understand that an appropriatefoundation for regulation and ethics is not somuch ``objectivity' as ``awareness.' In an agewhen ``consumers' are becoming concerned``citizens,' the relevant science must becomepost-normal.     

Impact of utilizing reflector,single-axis and two-axis sun trackers on the performance of an evacuated tube solar collector

ABSTRACT

In this paper, a novel evacuated tube solar collector (ETSC) is first designed and built. Then, the impact of adding reflector, reflector plus single-axis sun tracker and reflector plus two-axis sun tracker to the built ETSC on the thermal efficiency of the ETSC is evaluated both theoretically and experimentally. In this regard, four identical versions of the proposed ETSC have been built and utilized in four collectors built and presented in this research work. The first collector is the same proposed built ETSC, the second collector is a parabolic trough solar collector comprising one built ETSC and a reflector (ETSC+R), the third collector is composed of one built ETSC, a reflector and a single-axis sun tracker all built in this study (ETSC+R+ ST), and the fourth collector consists of one built ETSC, a reflector and a two-axis sun tracker all built in this study (ETSC+R+ DT). Theoretical basis and concepts of the four collectors are formulated and analyzed in separate subsections. Theoretical results are outlined and highlighted at the end of each subsection. Experimental measurements and data obtained from the operation of the four collectors in the four seasons are presented that point by point verify theoretical results obtained in this study. To provide a comprehensive view, a techno-economic numerical comparison is performed between the four collectors. The following points, which are also the novelty and contributions of this work, are deduced from theoretical concepts, experimental data, and comparison provided in this study:

?There is no technical and economic justification for adding a reflector to an ETSC that results in forming a parabolic trough solar collector (ETSC+R) without any sun tracker.

?There is no economic justification for adding a single-axis sun tracker to a parabolic trough solar collector (ETSC+R).

?There is no economic justification for adding a two-axis sun tracker to a parabolic trough solar collector (ETSC+R).

?Comparing between a two-axis sun tracker and a single-axis sun tracker, adding the single-axis type to a parabolic trough solar collector (ETSC+R) is more advantageous.
