Concerns about the unsustainability of the conventional food system have brought attention to so called alternative food networks, which are widely thought to be more sustainable. However, claims made about AFNs’ sustainability have been subject to a range of criticisms. Some of them present counterevidence, while others have pointed to problematic underlying features in the academic literature and popular discourse that may hamper our understanding of AFNs’ sustainability. Considering these criticisms, together with the fact that the literature often addresses a (...) specific type of AFN or a specific sustainability-related issue, it is hard to form a clear overall picture of the sustainability promise of AFNs. In this article, we seek to contribute to a clearer understanding of this promise through a structured review, focusing on links between AFN characteristics and sustainability. Through an analysis of AFN conceptualizations reflected in the literature, we identify and consolidate their key characteristics. We then synthesize claims of how these characteristics may translate into sustainability, finding a wide range of potential direct and indirect impacts. Examining these from different angles, we find that the sustainability promise of AFNs found in these claims is qualified by the presence of potentially unaddressed issues, by criticisms regarding for example the evidence base of the assumed impacts and their power in addressing sustainability, and by considerations of how these impacts might play out in actual, real-life food networks. Indirect impacts of learning and participation may be highly significant for sustainability. We conclude with recommendations for research and practice. (shrink)

The literature on quantum logic emphasizes that the algebraic structures involved with orthodox quantum mechanics are non distributive. In this paper we develop a particular algebraic structure, the quasi-lattice ( $${\mathfrak{I}}$$ -lattice), which can be modeled by an algebraic structure built in quasi-set theory $${\mathfrak{Q}}$$. This structure is non distributive and involve indiscernible elements. Thus we show that in taking into account indiscernibility as a primitive concept, the quasi-lattice that ‘naturally’ arises is non distributive.

This special issue brings together contributions from nine scholars who have been working at the frontiers of the comparative study of risk. Most of the papers that follow use a cross-national approach to investigate public attitudes to risk in a broad range of settings including Germany, Sweden, Denmark, England, and the United States. Two of the authors represented here adopt more creative interpretations for carrying out comparative studies that reach considerably beyond conventional methodologies of country-level contrasts. One contributor highlights the (...) temporal dimensions of novel forms of environmental uncertainty and a second selection, grounded in the sociology of language, compares the different objectives that lay people seek to satisfy when they speak about risk. In this sense, this issue provides a farrago of perspectives on the most befitting way to exploit the utility of comparative methodologies.Political scientists interested in the effects of different regulatory regimes and systems of governance have been responsible for most comparative risk research conducted to date. The papers in this issue depart from this tradition and instead draw on insights derived from social theory. There has been over the past decade a dramatic upswelling of interest in risk among theoretically-inclined sociologists and several writers have suggested that a pervasive sense of anxiety is a central feature of the current phase of modernity (e.g., Giddens, 1990; Beck, 1992). This collection represents an initial attempt to situate these recondite impressions in distinct contexts and to scrutinise them from a variety of comparative perspectives. (shrink)

Over the past decade risk society theory has become increasingly prominent within the field of environmental social theory. This perspective contends that conventional political divisions based on class are becoming less salient and are giving way to a politics predicated upon the distribution of risk. There is much in risk society theory, especially its central contention that public anxieties about high consequence-low probability events undermine the legitimacy of science, that has a distinctly German stamp. Through a comparative analysis of how (...) national context has differently shaped science as a public epistemology this paper suggests we should tread carefully in moving to accept the general applicability of this theoretical approach.

Frente a la esclavitud natural defendida por Aristóteles, algunos intentan salvaguardar la coherencia interna del discurso, mientras que otros la niegan. Sin pretender un juicio valorativo, se busca esclarecer la naturaleza del esclavo, de la mujer y de las relaciones entre señor, mujer y esclavo en el oikos.

Concepts are the building blocks of higher-order cognition and consciousness. Building on Conceptual Spaces Theory (CST) and proceeding from the assumption that concepts are inherently dynamic, this paper provides historical context to and significantly elaborates the previously offered Iterative Subdivision Model (ISDM) with the goal of pushing it toward empirical testability. The paper describes how agents in continuous interaction with their environment adopt an intentional orientation, estimate the utility of the concept(s) applicable to action in the current context, engage in (...) practical action, and adopt any new concepts that emerge: a largely pre-intellectual cycle that repeats essentially without interruption over the conceptual agent’s lifetime. This paper elaborates utility optimization by establishing three constraints on concept formation/evaluation – non-redundancy, distinctiveness, and proportionality – embedding them in a quasi-mathematical model intended for development into a formal logic. The notion of a distinctor – a quality dimension of the conceptual space in focus at any given time, used for making what we call a difference distinction – is key. The primary contribution of the revised ISDM is the way it relates concepts to action via utility optimization/actualization and the way it describes the emergence of quality dimensions through trial-by-action (trial and error), something previous presentations of CST have failed to address.

The aim of this paper is to explain, by means of Aristotelic texts, the answer to two questions related to the mentioned concepts: 1) What is the goal and purpose of the philosophy of human things?: and 2) To whom is this knowledge addressed?

The purpose of this paper which centers on the anthropology and ethics of St. Thomas Aquinas is to articúlate «conscience and choice» from the realistic viewpoint, thus ordering the concepts of law, synderesis, conscience, deliberation and choice.

In this paper, we look at the new frontier of e-commerce, the ethical challenges it is facing and discuss some of the problems encountered and some of the solutions that are evolving. The areas of concern include the impact on other businesses, investors and consumers. Problems regarding financial reporting, intellectual property and privacy are discussed.

An ecosystem is like Kantian totality: it cannot be reduced to object of knowledge, since each element of it is internal to the contingent correlation which sustains it. Its accidental metamorphoses create worlds of sense which are infinitely on the way.
