Technologies and services provided to resource-poor farmers need to be relevant and compatible with the context in which they operate. This paper examines the contribution of extension services to the food security of resource-poor farmers in a rural village in South Africa. It considers these in terms of the local context and the production of African vegetables in household food plots. A mixture of participatory, qualitative and quantitative research tools, including a household survey, is used to argue that local production (...) practices contribute more to food security requirements than the extension services. This is because of the ability of African vegetables to grow relatively well in semi-arid areas where other exotic plants do not, their ability to provide at least two foodstuffs during their life cycle, and the ability of either the fruit or the leaves, or both, to be dried and stored for consumption in the winter months. These crops can make a significant contribution in terms of household food security, but a number of social and agroecological factors are constraining their production and placing their availability under threat. Despite this, the extension services remain focused on certain activities within vegetable garden projects, even when these are not meeting their proposed purpose—food security by means of cash-crop production. The paper concludes that social and agroecological constraints could be improved if the extension services were changed. This could include the use of context specific and low-cost technologies to ensure that these crops are able to increase their contribution to household food security for resource-poor farmers in semi-arid areas.

The microbiome of human hair follicles (HFs) has emerged as an important player in different HF and skin pathologies, yet awaits in‐depth exploration. This raises questions regarding the tightly linked interactions between host environment, nutrient dependency of host‐associated microbes, microbial metabolism, microbe‐microbe interactions and host immunity. The use of simple model systems facilitates addressing generally important questions and testing overarching, therapeutically relevant principles that likely transcend obvious interspecies differences. Here, we evaluate the potential of the freshwater polyp Hydra, to dissect (...) fundamental principles of microbiome regulation by the host, that is the human HF. In particular, we focus on therapeutically targetable host‐microbiome interactions, such as nutrient dependency, microbial interactions and host defence. Offering a new lens into the study of HF – microbiota interactions, we argue that general principles of how Hydra manages its microbiota can inform the development of novel, microbiome‐targeting therapeutic interventions in human skin disease.

Employability is one of the leading challenges of the contemporary organizational environment. While much is known about the positive effects of job crafting on employees’ employability in general, little is known about its effects when employment contacts are different. Differentiating between temporary and permanent workers, in this article we investigate how in the environment of psychological safety, these two types of employees engage in job crafting, and how job crafting is related to their perceived employability. Data were collected among two (...) samples, consisting of temporary agency workers ( N = 527), and permanent employees ( N = 796). Structural equation modeling (SEM) analyses indicated a different pattern of results for the two groups: for permanent employees, increasing challenging job demands was positively, and decreasing hindering job demands was negatively related to perceived employability. Moreover, psychological safety was related to all job crafting dimensions. For agency workers, only increasing structural job resources was related to employability, while psychological safety was negatively associated with crafting hindrances. These findings suggest that a climate of psychological safety is particularly effective for permanent employees in fostering job crafting and employability. (shrink)

This collection by some of the leading scholars of Strauss's work is the first devoted to Strauss's thought regarding education. It seeks to address his conception of education as it applies to a range of his most important concepts, such as his views on the importance of revelation, his critique of modern democracy and the importance of modern classical education.

Since its discovery in 1959 the Aharonov-Bohm effect has continuously been the cause for controversial discussions of various topics in modern physics, e.g. the reality of gauge potentials, topological effects and nonlocalities. In the present paper we juxtapose the two rival interpretations of the Aharonov-Bohm effect. We show that the conception of nonlocality encountered in the Aharonov-Bohm effect is closely related to the nonseparability which is common in quantum mechanics albeit distinct from it due to its topological nature. We propose (...) a third alternative interpretation based on the loop space of holonomies which serves to solve some of the problems and we trace back the topological nonlocality and thereby the Aharonov-Bohm effect to their quantum mechanical origin. All three discussed interpretations are, of course, empirically equivalent. In fact, they present us with an instructive case study for the thesis of theory underdetermination by empirical data.

The study of historiography is undergoing a revolution akin to that which took place in the history of political thought in the 1960s, and the work of J.G.A. Pocock is central to both. Pocock's continuing exploration, in Barbarism and Religion (1999-), of the intellectual contexts of Gibbon's History of the Decline and Fall of the Roman Empire, is central to this enterprise, and this essay situates the origins of his own work within a pre-‘Cambridge School’ Cambridge and its experience of (...) what might be called the Butterfieldian moment. That was marked by a desire to treat religion seriously as a driving force in history; and the same concern is applied here to further understanding an eighteenth-century controversy in which history and religion were dramatically involved, and which profoundly affected Gibbon's own historical and religious views. The work of Conyers Middleton and John Jortin is critically examined from this perspective. These preludes to Gibbon lead to a series of postludes examining the particular contexts in which Victorian and twentieth-century historians and writers, from Henry Hart Milman to Evelyn Waugh, variously appreciated and interpreted Gibbon. The whole is to be seen as a reflexive engagement with Pocock's vitally illuminating studies in eighteenth-century historiography. ☆ A slightly revised version of a lecture given at the University of Sussex on 22nd May 2008, on the occasion of a colloquium devoted to J.G.A. Pocock's Barbarism and Religion. It had originally acted as a prelude to a lecture by Pocock on the same occasion, subsequently published as ‘Gibbon and the invention of Gibbon: chapters 15 and 16 reconsidered’, History of European Ideas 35 (2009), 209–16. In this sense, therefore, the present essay has become a postlude. I am deeply grateful to Noël Sugimura for generously reading and commenting on the rescoring of a lecture into an essay. (shrink)

We compare the definition of virtue in philosophy with the definition and operationalization of virtue in psychology. We articulate characteristics that virtue is presented as possessing in the perennial western philosophical tradition. Virtues are typically understood as (a) dispositional (b) deep-seated (c) habits (d) that contribute to flourishing and (e) that produce activities with the following three features: they are (f) done well, (g) not done poorly, and (h) in accordance with the right motivation and reason. We form a definition (...) from these characteristics and defend our exclusion of some other characteristics from the definition. Using our definition as a rubric, we evaluate conceptions of virtue in psychology, showing how many fall short at operationalizing at least one component of the philosophical notion of virtue.

Although a number of anthologies on the philosophy of punishment have been published in recent years, the inclusion of a number of important but rarely reprinted articles makes this volume a valuable addition to the field. Included are such historically important figures as Plato, Thomas Hobbes, and St. Thomas Aquinas; such rarely included figures as G. B. Shaw, Samuel Butler and Karl Marx; the important but ignored Mill-Gilpin controversy on capital punishment; and the hitherto nearly inaccessible paper by Richard Wasserstrom, (...) "Why Punish the Guilty?" Along with these fresh selections are numerous influential, widely-reprinted classical and contemporary essays. The selections are grouped into five sections, the largest of which, constituting nearly half the text, deals with the justification of punishment. The various justificatory theories are classified as teleological, retributivist, and teleological retributivist. The latter theory, not clearly defined by the editor, is represented by W. D. Ross, H. L. A. Hart, J. D. Mabbott, and K. G. Armstrong, who relate the teleological and retributivist elements in their theories in quite different ways. A section entitled "Alternatives to Punishment" provides selections which question the justice of punishment, its deterrent effect and the success of our present penal system. The other sections deal with the strict liability issue, the concept of punishment and the death penalty. Although containing good selections, the sections dealing with the latter two topics, including four and three articles respectively, are quite short. There are long bibliographies for each section and an introductory article by Professor Ezorsky examining the various justifications offered for punishment and arguing for a teleological retributivist theory.—M.G.

This contribution highlights the importance of the work of Hedwig Conrad-Martius, a student of Husserl and early phenomenological thinker, in the context of a review of James Hart’s 1972 dissertation on her work, now published under the title _Hedwig Conrad-Martius’ Ontological Phenomenology_. It provides some context for Conrad-Martius’ thought, gives a brief chapter-by-chapter account of Hart’s treatment, and raises some further questions about his discussion of her work.

This paper attempts to delineate some of the principal features and tasks of a politics of postmodernity. An attempt is made in the first part of the paper to reflect on the democratic revolutions of 1989 in Eastern Europe and to discern what lessons they might have to offer. What is called for, it is maintained, is a renewed theory of democracy and, more particularly, a reformulation of traditional liberalism. In the second part of the paper the author seeks to (...) suggest how such traditional liberal concepts as the individual, reason, universality, and freedom can be reformulated in a genuinely postmetaphysical, postmodern fashion.

The argument of this paper rests on the distinction between two types of what are, loosely speaking, logical claims: A general (speaker-independent) claim that some favoured principle of inference is both truth-preserving, and consistent with certain others. A claim by a particular speaker that he/she has reasonable deductive grounds for concluding that some particular statement is true. The first is a matter of pure logic—a question of what (allegedly) follows from what. The second is a matter of epistemic logic—a question (...) of whether someone has, or more generally, whether there are, reasonable deductive grounds for concluding that something is the case. I shall argue that this distinction has a crucial bearing on the disagreement between classical logicians and non-classical logicians, which is essentially a disagreement about inferential behaviour. The argument is laid out in a manner designed to maximise the chances of any errors being detected. The paper concludes with some considerations of the relevance of relevant logic to the psychologist investigating inference behaviour. (shrink)

In the article "The Epistemological Nature of Information Modeling" [Gnoseologicheskaia priroda informatsionnogo modelirovaniia], Voprosy filosofii, 1963, No. 10, Academician V. M. Glushkov examines two important methodological aspects of the modeling of natural objects and phenomena in the contemporary natural sciences. The first consists of the informational nature of the models created, and the second of their dynamism. The dynamic nature of today's models in the natural sciences means that it is not so much the material structure of the object that (...) is modeled as its behavior and functions in some sphere of natural phenomena. In this sense, the models under examination may also be termed functional, as distinct from the structural models pertaining to a static description of objects. (shrink)
