The ethical nature of transformational leadership has been hotly debated. This debate is demonstrated in the range of descriptors that have been used to label transformational leaders including narcissistic, manipulative, and self-centred, but also ethical, just and effective. Therefore, the purpose of the present research was to address this issue directly by assessing the statistical relationship between perceived leader integrity and transformational leadership using the Perceived Leader Integrity Scale (PLIS) and the Multi-Factor Leadership Questionnaire (MLQ). In a national sample of (...) 1354 managers a moderate to strong positive relationship was found between perceived integrity and the demonstration of transformational leadership behaviours. A similar relationship was found between perceived integrity and developmental exchange leadership. A systematic leniency bias was identified when respondents rated subordinates vis-à-vis peer ratings. In support of previous findings, perceived integrity was also found to correlate positively with leader and organisational effectiveness measures. (shrink)

We attempt to quantify and qualify the preferences of consumers for beef with a number of environmental and food quality attributes. Our goal is to evaluate the viability of a proposed food co-operative based in the Wood River watershed of southern Saskatchewan, Canada. The food co-operative was designed to provide a price premium to producers who adopted alternative management practices. In addition, the study evaluated the acceptance of a proposed food co-operative by consumer that had environmental interests as compared to (...) the general population. Conjoint analysis was used to determine the trade-off and relative value of beef with the following production and purchasing characteristics: (a) use of hormones, antibiotics and vaccination in production; (b) method of obtaining the beef including monthly or yearly purchase contracts or a local market; (c) price relative to beef purchased from the local grocery store; and (d) impact on the river ecosystem. Consumers from environmental groups had stronger environmental and food quality preferences than individuals from the general population. However, consumers from both groups expressed a willingness to pay higher prices for food that had these attributes. It was uncertain whether the magnitude of the premium, in combination with a desire not to enter a long-term purchasing commitment, would be large enough to encourage farmers to adopt the alternative management.

Readers of Eastern Christianity and Late Antique Philosophy will find a collection of authoritative papers from across the Neoplatonic and Eastern Christian traditions. It is only recently that scholars have started to take notice of the Eastern Christian engagement with late antique philosophical texts. This volume builds upon this new interest in order to show the dynamic nature of Neoplatonism and Eastern Christianity at a time when both faced a variety of challenges. The legacy of Greek philosophy in the Christian (...) East fills the gap between the schools of Alexandria and Baghdad and brings into focus the intellectual history of the period. The aim of the volume is to stimulate interest in late antique philosophy and its reception in the Christian East. (shrink)

it is a pleasant task to reflect on these thoughtful comments on my Coss lecture. Their gracious reception of an economist into the world of philosophy is an added bonus.Let me leave to one side—for the moment—the main title of my paper, and focus on the subtitle: “the collective construction of rules to live by.” Here, we find my core interest in both economics and philosophy. Beginning around the middle of the twentieth century, economists claimed to have the necessary tools (...) for deriving the optimal rules to live by. Once that claim was taken seriously by the profession, it became accepted practice for economists to become advocates for those decision rules. More correctly, economists became advocates for a..

This study reports on action research efforts that were aimed at developing institutional arrangements beneficial for soil fertility improvement. Three stages of action research are described and analyzed. We initially began by bringing stakeholders together in a platform to engage in a collaborative design of new arrangements. However, this effort was stymied mainly because conditions conducive for learning and negotiation were lacking. We then proceeded to support experimentation with alternative arrangements initiated by individual landowners and migrant farmers. The implementation of (...) these arrangements too ran into difficulties due to intra-family dynamics and ambiguities regarding land tenure. Further investigations to find out how ambiguities could be tackled revealed that the local actors themselves had taken initiatives towards developing institutional innovations to reduce ambiguities. However, there is still considerable scope for further development of these self-organized innovations. The article ends with a reflection on inter-disciplinary action research, where it is argued that making “mistakes” is an inherent and necessary characteristic in action research that aims to address complex social issues.

O artigo de Goodman “The Problem of Counterfactual Conditionals” teve um papel central no debate relativo a análise adequada dos condicionais contrafactuais. A seguir examinarei o artigo de Goodman em detalhe e discutirei algumas objeções e sugestões de Parry em seu artigo “A Reexamination of the Problem of Counterfactual Conditionals”. Restringirei minha discussão ao “problema das condições relevantes”, assim denominado por Goodman, que é o tema principal das críticas de Parry e que considero ser o problema principal para (...) a abordagem de Goodman. doi: http://dx.doi.org/10.5007 / 1808-1711.2011v15n3p383.

This important book features collected essays on the distinguished psychoanalyst Dr. Michael Eigen, who has emerged as an influential innovator within and beyond psychoanalysis. Drawing on the ideas of W. R. Bion, Winnicott, the Kabbalah, artists and scientists, Eigen's work is noted for its creativity which combines spirituality with psychoanalysis. The book begins with a series of articles on Eigen's perspective on time, before covering topics such as the evolution of the psyche, mystery and metaphor, and breakdown and recovery. These (...) papers feature a rich array of subjects and reflections, with many clinical examples and applications to domains beyond psychotherapy, including politics, societal contexts and creativity. Dr. Eigen is one of the most influential psychoanalysts of the current era and this collection of essays provides insightful discussion on his ideas. This celebration of Michael Eigen will fascinate any psychoanalyst interested in his work. (shrink)

There is an intimate connection between proofs of the natural deduction systems and typed lambda calculus. It is well-known that in simply typed lambda calculus, the notion of formulae-as-types makes it possible to find fine structure of the implicational fragment of intuitionistic logic, i.e., relevant logic, BCK-logic and linear logic. In this paper, we investigate three classical substructural logics (GL, GLc, GLw) of Gentzen's sequent calculus consisting of implication and negation, which contain some of the right structural rules. In terms (...) of Parigot's -calculus with proper restrictions, we introduce a proof term assignment to these classical substructural logics. According to these notions, we can classify the -terms into four categories. It is proved that well-typed GLx--terms correspond to GLx proofs, and that a GLx--term has a principal type if stratified where x is nil, c, w or cw. Moreover, we investigate embeddings of classical substructural logics into the corresponding intuitionistic substructural logics. It is proved that the Gödel-style translations of GLx--terms are embeddings preserving substructural logics. As by-products, it is obtained that an inhabitation problem is decidable and well-typed GLx--terms are strongly normalizable. (shrink)

We provide a logical matrix semantics and a Gentzen-style sequent calculus for the first-degree entailments valid in W. T. Parry’s logic of Analytic Implication. We achieve the former by introducing a logical matrix closely related to that inducing paracomplete weak Kleene logic, and the latter by presenting a calculus where the initial sequents and the left and right rules for negation are subject to linguistic constraints.
