The hazard of postharvest pest losses is ubiquitous in peasant farming systems; as a result, farmers invariably have some response to the threat of these losses. Responses to postharvest pests may be more extensive than to field pests, even when, by statistical measures, the usual levels of losses are comparable. In studies of pest management practices in three contrasting areas in Kenya, it was found that farmers virtually always rely on an array of techniques and strategies, usually including both older (...) and more modern practices. There is considerable variation among regions in the techniques used, due not only to climatic and socioeconomic factors, but also to variations in cultural history and preferences. The ways in which management practices have changed over time also vary by region. The major changes have been related to overall system change. Four main sources of change have been paramount: (1) population growth and the intensification of land use; (2) the introduction of new cash crops; (3) the introduction of new marketing infrastructure; and (4) the perception of increased environmental risk. Their effect on the replacement of older practices by newer ones is often interrelated. Traditional techniques are often based on materials derived from bushland, but increasing population density makes these difficult to continue as bushland and its common property resources disappear. Simultaneously, tolerance for losses is reduced as land availability is constrained. With the introduction of a cash crop infrastructure, new methods of pest management, especially pesticide use, become more readily available and may spread rapidly. Areas with good market infrastructure but varying population density may still differ considerably because with abundant land it is possible to compensate for expected losses by additional planting.A study of an FAO project to improve postharvest management through earlier harvesting and a redesigned storage crib indicate some reasons for its lack of widespread acceptance. Little or no attempt was made to adapt techniques to varying circumstances; instead, a single “solution” was meant to be applied across areas of vastly different conditions. In many cases, this project represented a radical response to a problem farmers considered they were coping with acceptably using existing methods. Although it probably represents an improvement over traditional storage methods in purely technical terms, the new technique also often involved major costs, readjustments, and cultural disruptions that may not have been anticipated by its designers. More likely to succeed would be a strategy that begins with some of farmers' existing practices and whose objective is to develop and offer a range of possible improvements from which farmers could select individual components appropriate to their conditions and needs.

The study aimed to identify the relationship between correcting the deviations in the measurement of performance and achieving the objectives of control and the performance of the job at the Islamic University in the Gaza Strip. To achieve the objectives of the research, the researchers used the descriptive analytical approach to collect information. The questionnaire consisted of (20) statements distributed to three categories of employees of the Islamic University (senior management, faculty members, their assistants and members of the administrative board). (...) A random sample of 314 employees was selected and 276 responses were retrieved with a recovery rate of 88.1%. The Statistical Analysis Program (SPSS) was used to enter, process, and analyze the data. The results of the study showed a positive relationship between correcting deviations in performance measurement and achieving the control objectives represented by the functional performance in the Islamic University from the point of view of the members (senior management, faculty and their assistants, and the administrative board), where the relative weight of all the paragraphs was (74.25%). The study recommended the need to ensure that the actual performance of the planned performance is matched and decisions are taken to correct the serious deviations and take the necessary measures in terms of retraining and change in regulations, wages and bonuses and punishment of the culprit, neglect and negligence by mistake.

: Lately there is more attention paid to technological development in intelligent tutoring systems. This field is becoming an interesting topic to many researchers. In this paper, we are presenting an intelligent tutoring system for teaching DES Information Security Algorithm called DES-Tutor. The DES-Tutor target the students enrolled in cryptography course in the department Information Technology in Al-Azhar University in Gaza. Through DES-Tutor the student will be able to study course material and try the exercises of each lesson. An evaluation (...) of the DES-Tutor was carried out and the results were promising.

People are minded creatures; we have thoughts, feelings and emotions. More intriguingly, we grasp our own mental states, and conduct the business of ascribing them to ourselves and others without instruction in formal psychology. How do we do this? And what are the dimensions of our grasp of the mental realm? In this book, Alvin I. Goldman explores these questions with the tools of philosophy, developmental psychology, social psychology and cognitive neuroscience. He refines an approach called simulation theory, which (...) starts from the familiar idea that we understand others by putting ourselves in their mental shoes. Can this intuitive idea be rendered precise in a philosophically respectable manner, without allowing simulation to collapse into theorizing? Given a suitable definition, do empirical results support the notion that minds literally create surrogates of other peoples mental states in the process of mindreading? Goldman amasses a surprising array of evidence from psychology and neuroscience that supports this hypothesis. (shrink)

Abed Azzam offers a fresh interpretation of Nietzsche's engagement with the work of Paul the Apostle, reorienting the relationship between the two thinkers while embedding modern philosophy within early Christian theology. Paying careful attention to Nietzsche's dialectics, Azzam situates the philosopher's thought within the history of Christianity, specifically the Pauline dialectics of law and faith, and reveals how atheism is constructed in relation to Christianity. Countering Heidegger's characterization of Nietzsche as an anti-Platonist, Azzam brings the philosopher closer to Paul through (...) a radical rereading of his entire corpus against Christianity. This approach builds a compelling new history of the West resting on a logic of sublimation, from ancient Greece and early Judaism to the death of God. Azzam discovers in Nietzsche's philosophy a solid, tangible Pauline structure and virtual, fragile Greek content, positioning the thinker as a forerunner of the recent "return to Paul" led by Badiou, Agamben, Žižek, and Breton. By changing the focus of modern philosophical inquiry from "Nietzsche and philosophy" to "Nietzsche and Christianity," Azzam initiates a major challenge to the primacy of Plato in the history of Western philosophy and narrow certainties regarding Nietzsche's relationship to Christian thought.

Why do we, today’s people, owe a duty to future generations with whom we will not overlap? In my paper, I aim at answering this question step by step. The first step is to respond to the question why human beings should continue to exist. I try this by critically considering Karl-Otto Apel’s argument for the survival of human beings from the viewpoint of his own discourse ethics. This consideration, however, leads us to the second step where we are faced (...) with the following question : For what reason do we – this particular generation and no other – owe a duty to future people? In order to answer this, I will interpret John Locke’s Two Treatises of Government and Book of Rites, a Chinese classic of Confucianism. From this interpretation, I would like to conclude that we are responsible for future people as far as we are responsible to past generations who delegated such future-oriented responsibility to us.

The first century B.C. poet Lucretius put forth an argument for why death is not bad for the person who has died. This argument is commonly referred to as Lucretius’s “symmetry argument” because of its assumption that the period before we were born is symmetrical to the period after we die. Jeremy Simon objects to the symmetry argument, claiming that the two periods are not relevantly symmetrical: being born earlier than we actually are born would not guarantee us more life, (...) whereas extending our lifespan past the time we actually would die would guarantee us more life. Simon believes this difference between the two time periods also explains why it is reasonable for people to wish for a later death but not for an earlier birth. We raise several objections to Simon’s response. Our main objection is that insofar as people do not wish for an earlier birth, it is not because they fear losing more life, but rather is a result of being concerned about losing what is important about life, namely its unique content.

In “Justice at the Margins: The Social Contract and the Challenge of Marginal Cases” (Southern Journal of Philosophy, 55.1), Nathan Bauer and David Svolba appeal to a concept of recognition found in social contract theory to argue that all humans, including humans who lack certain unique cognitive abilities, so‐called marginal cases, have rights that nonhuman animals lack. The main reason is that we can recognize ourselves in all humans, but not in nonhuman animals. I argue (i) that it is unclear (...) that we can recognize ourselves in certain types of marginal cases, such as corpses and embryos; (ii) that Bauer and Svolba’s reason for why we cannot recognize ourselves in nonhuman animals is questionable; and (iii) if we can recognize ourselves in any types of marginal cases, then we should be able to recognize ourselves in nonhuman animals.

Maybe God doesn’t have to do anything in order to bring it about that there be light. Most of us, however, have to perform some sort of act like flicking a switch to do so. But some of the things we bring about do not require such mediating acts. For example, it appears that I don’t have to do anything in order to bring about or cause the arm movements I perform in flicking the switch. I just move my arm. (...) Of course, a number of things will happen when I move my arm: neurons fire, muscles flex. But these are not acts in and of themselves. The only act we have here is the moving of the arm. So my arm movement in this instance is basic in a sense in which my illumination of the room is not. (shrink)

Alvin Goldman examines public and private methods or "pathways" to knowledge, arguing for the epistemic legitimacy of private and introspective methods of gaining knowledge, yet acknowledging the equal importance of social and public mechanisms in the quest for truth.

Since its inception, Stakeholder Management Capability (SMC) has constituted a powerful hermeneutic through which business organizations have understood and leveraged stakeholder relationships. On this model, achieving a high level of capability largely depends on managerial ability to effectively bargain with stakeholders and establish solidarity vis-à-vis the successful negotiation, implementation, and execution of "win–win" transactional exchanges. Against this account, it is rightly pointed out that a transactional explanation of stakeholder relationships, regarded by many as the bottom line for stakeholder management, fails (...) to provide managerial direction regarding how to resolve a variety of normative stakeholder claims that resist commoditization. In response to this issue, this paper has two overlapping goals. It seeks to elaborate a discourse theoretical approach to the problem by first drawing out Jurgen Habermas’ theory of communicative action and delineating the various types of rational discourse. Second, the paper attempts to present concrete implications for SMC relative to reshaping the contours of rational, process, and transactional analysis in light of central discourse theoretical conclusions.

Whatever is distributed must first be produced, and since the recipients are also the producers there will be constraints on distribution determined by productive necessity. Standard theories of distributive justice systematically ignore these constraints. In light of these considerations I define what it is that must be produced and how it must be distributed in order to assure continued production. Desert, equality, entitlement, and the other values normally associated with distributive justice must take a back seat to the need to (...) assure that there is anything to distribute at all.

The term ‘sporting integrity’ is widely used in the normative assessment of sports. The term, however, suffers from a lack of conceptual precision. Alfred Archer’s ‘coherence-view’ of sporting integrity goes a long way to help clarify what ‘sporting integrity’ actually means and the specific institutional and individual obligations that it generates. Archer argues that ‘sporting integrity’ essentially means that the constraints athletes face ‘cohere’, in the sense of applying consistent inefficiencies between athletic competitors. For example, those who use performance enhancing (...) drugs are less constrained than those who do not use PEDs, and thus PED use undermines sporting integrity. This paper presents the argument that over and above competitive coherence, sporting integrity means living up to the ‘spirit’ or ‘ethos’ of a game. The implications of this view are that a sport could have ‘coherent’ competitive constraints and still lack sporting integrity; additionally, a sport could have ‘i... (shrink)

Recognizing the importance of health‐promoting relationships in engaging people who are experiencing homelessness in care, most research on health clinics for homeless persons has involved some recognition of client–provider relationships. However, what has been lacking is the inclusion of a critical analysis of the policy context in which relationships are enacted. In this paper, we question how client–provider relationships are enacted within the culture of community care with people who are experiencing homelessness and how clinic‐level and broader social and health (...) policies shape relationships in this context. We explore these questions within a critical theoretical perspective utilizing a critical ethnographic methodology. Data were collected using multiple methods of document review, participant observation, in‐depth interviews and focus groups. The participants include both clients at a community health clinic, and all clinic service providers. We explore how clients and providers characterized each other as ‘good’ or ‘bad’. For providers, this served as a means by which they policed behaviours and enforced social norms. The means by which both providers’ and clients’ negotiated relationships are explored, but this is couched within both local and system‐level policies. This study highlights the importance of healthcare providers and clients being involved in broader policy and systemic change. (shrink)

This paper describes and argues for the inclusion of a modified form of Venn diagrams in critical thinking courses and textbooks. The modified Venn Diagrams, it is argued, are easier to learn as they more clearly show the meanings of inclusion and exclusion, easier to use when solving problems (including those found on LSAT exams), are often included in LSAT preparatory material, and students tend to have a more thorough understanding of the concept of logical possibility after having used modified (...) Venn diagrams. (shrink)

Social epistemology is the study of the social dimensions of knowledge or information. There is little consensus, however, on what the term "knowledge" comprehends, what is the scope of the "social", or what the style or purpose of the study should be. According to some writers, social epistemology should retain the same general mission as classical epistemology, revamped in the recognition that classical epistemology was too individualistic. According to other writers, social epistemology should be a more radical departure from classical (...) epistemology, a successor discipline that would replace epistemology as traditionally conceived. The classical approach could be realized in at least two forms. One would emphasize the traditional epistemic goal of acquiring true beliefs. It would study social practices in terms of their impact on the truth-values of agents' beliefs. A second version of the classical approach would focus on the epistemic goal of having justified or rational beliefs. Applied to the social realm, it might concentrate, for example, on when a cognitive agent is justified or warranted in accepting the statements and opinions of others. Proponents of the anti-classical approach have little or no use for concepts like truth and justification. In addressing the social dimensions of knowledge, they understand "knowledge" as simply what is believed, or what beliefs are "institutionalized" in this or that community, culture, or context. They seek to identify the social forces and influences responsible for knowledge production so conceived. Social epistemology is theoretically significant because of the central role of society in the knowledge-forming process. It also has practical importance because of its possible role in the redesign of information-related social institutions. (shrink)

Against the traditional view, Alvin Goldman argues that logic, probability theory, and linguistic analysis cannot by themselves delineate principles of rationality or justified belief. The mind's operations must be taken into account.

Knowledge in a Social World offers a philosophy for the information age. Alvin Goldman explores new frontiers by creating a thoroughgoing social epistemology, moving beyond the traditional focus on solitary knowers. Against the tides of postmodernism and social constructionism Goldman defends the integrity of truth and shows how to promote it by well-designed forms of social interaction. From science to education, from law to democracy, he shows why and how public institutions should seek knowledge-enhancing practices. The result is (...) a bold, timely, and systematic treatment of the philosophical foundations of an information society. (shrink)
