This chapter reviews fundamental ethical controversy surrounding the ongoing effort to revise the Uniform Determination of Death Act in the United States. Instead of focusing on the process of the revision itself, the chapter explores the underlying ethical debate over brain death that has been ongoing for many decades and finally culminated in this revision. Three issues are focused: the requirement for consent and personal exemptions before applying brain death for the diagnosis of death; redefining the areas of the brain (...) that have ceased to function in the definition of brain death; and codifying the American Academy of Neurology as the authority to issue the standards of the diagnosis of brain death. The chapter concludes that allowing the personal choice of death determination gives a pragmatic compromise to the disputed definition and practice of diagnosing brain death. So long as all risks and imperfections of the diagnosis are accepted through the consenting process, there is nothing ethically objectionable to continuing the current practice of diagnosing brain death as a successful tool to facilitate heart-beating organ donation without violating the dead-donor rule. By contrast, precluding personal choice and imposing legal restrictions to consent and exemptions would further erode public trust. (shrink)

: 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.

In this paper I investigate the possibility of a dictatorship in the context of Harsanyi's Social Aggregation Theorem. Preliminarily, some propositions about Harsanyi's Theorem are presented using an alternative principle that I name Quasi-strong Pareto, which is the latter part of Strong Pareto. Then I define dictatorship as a requirement that social preference agrees with a dictator's preference or those of members of dictatorial group even if their preferences strictly contradict those of all other people in the society. Conclusively, although (...) in each version of Harsanyi's Theorem with Pareto Indifference, Weak Preference Pareto or Weak Pareto the social utility function may have a form of dictatorship, however if individuals' vNM utility functions are all 'individualistic' and Quasi-strong Pareto is satisfied, then the dictatorship is excluded.

This paper investigates the semantics of measure phrases in Japanese. Based on new data, we argue that the interpretation of measure phrases in Japanese is sensitive to scale structure such that (i) measure phrases are introduced by a degree morpheme that selects only for gradable predicates whose scale contains a minimal element (i.e., a lower closed scale) and (ii) violations to this restriction are repaired via coercion, which forces a comparative interpretation with a contextually determined standard and hence a minimal (...) element. We compare the Japanese facts to data in other languages and argue that the requirement of having a minimal element is not specific to Japanese, but universal. We show that languages may vary in how they deal with potential violations of this universal constraint, including coercion of a contextually recoverable derived minimal element (Japanese), ungrammaticality (e.g., Spanish, Korean, Russian), and a hybrid system of ungrammaticality for some adjectives and allowed constraint violation for others (e.g., English, German, Italian).

Naturalistic teleological accounts of mental content rely on an etiological theory of function. Nanay has raised a new objection to an etiological theory, and proposed an alternative theory of function that attributes modal force to claims about function. The aim of this paper is both to defend and to cast a new light on an etiological theory of function. I argue against Nanay’s “trait type individuation objection,” suggesting that an etiological theory also attributes modal force to claims about function. An (...) etiological theory of function can be thought to analyze claims about function with modal force, not relying on any theory of counterfactuals. (shrink)

The social and cultural causes behind the widespread use and acceptance of robots in Japan are not yet completely understood. This study compares humans and robots in images gathered through Google searches in Japanese and in English. Numerous pictures obtained by the search in Japanese were found to have a human and a robot looking together at something else (“third item”), whereas many of the images acquired by search in English show a human and a robot facing each other. This (...) is similar to the composition of mother and child in paintings: in _ukiyo-e_ that was painted mainly in the Edo period of Japan, the mother and child are often depicted together viewing something other than themselves, whereas this is not the case in Western paintings of mother and child. It has also been pointed out that, in modern Western paintings, the world inside the picture is separated from the outside world, forming an independent microcosmos, whereas the inside and outside are continuous in Japanese paintings. These may indicate that, in Japanese society, robots are to a certain extent regarded as fellow human beings who can share the third item. In Western society, on the other hand, no code is embedded that can fix robots’ superiority or inferiority to humans, which would easily trigger an antagonistic view toward artificial intelligence (AI)/robots as threatening entities, as shown in most of Western literature and movies. We suggest that such cultural characteristics of Japanese society can contribute to enhance coexistence with AI/robots. (shrink)

The Japanese comparative adverb motto has two different uses. In the degree use, motto compares two individuals and denotes that there is a large gap between the target and a given standard with a norm-related presupposition. On the other hand, in the so-called ‘negative use’ it conveys the speaker’s attitude toward the utterance situation. I argue that similarly to the degree motto, the negative motto is a comparative morpheme, but unlike the degree motto it compares a current situation and an (...) expected situation at the level of conventional implicature /expressive. I argue that the speaker’s negative evaluation of the utterance situation in question comes from the large gap between the expected degree and the current degree. The theoretical implications of this paper are that there is a natural extension from semantic comparison to expressive comparison and that there is a type in natural language that can be called an ‘indirect expressive’, as opposed to ‘direct expressives’ like bastard and man.

This study investigates interpretations of the Japanese initial mora-based minimizer “X.Y...”-_no_ “X”-_no ji-mo_ ‘lit. even the letter “X” of “X.Y...”.’ Although initial mora-based minimizers have a literal interpretation of _ji_ ‘letter’, they have a non-literal interpretation as well. The non-literal interpretation has several distinctive features that are not present in ordinary minimizers. First, it is highly productive in that various expressions can appear in the form “X.Y...”-_no_ “X”-_no ji_. Second, non-literal minimizers typically co-occur with predicates that relate to knowledge, information, (...) concepts, thought, and habituality, as seen in the corpus data (Balanced Corpus of Contemporary Written Japanese [BCCWJ]). I argue that in the non-literal use, X refers to the minimum on the scale of the main predicate concerning “X.Y...”. I suggest that the non-literal use was developed as a result of the conventionalization of the pragmatic inference derived from the literal reading, and that the co-occurrence with predicates related to knowledge, information, knowledge, concepts, thought, or habituality is due to the interpretation of “X.Y...”, which were originally interpreted as letters as an abstract concept. The theoretical implication of this study is that, in addition to a non-compositional (lexically specified) minimizer whose scale is lexically fixed (e.g., _give a damn_, _lift a finger_), there also exists a compositional (lexically unspecified) minimizer in natural language, whose scale is specified via the predicate with which the minimizer co-occurs. The last section of this paper briefly discusses similar/related phenomena in Bosnian/Croatian/Serbian, Korean, and English from a cross-linguistic perspective. (shrink)

This book, written by one of the leading Japanese scholars in the philosophy of agricultural science, examines the relationship between human life, the natural environment, and agriculture.

Rauszer and Sabalski proved in [2] that distributivity with respect to infi- nite joins and meets is a sucient and necessary condition making the RasiowaSikorski Lemma valid in distributive lattices. The main part of their proof is a direct construction of a required filter under distributivity. In this note we show that a generalization of the result can be obtained from the Rasiowa-Sikorski Lemma for Boolean algebras by using Gornemann’s result in [1] instead of a direct con- ¨ struction. Suppose (...) A is a distributive lattice and Q; R 2 A f;g. We call A complete if 8M 2 Q9 M 2 A and 8N 2 R9 F N 2 A. M 2 Q is -dis if 9 M 2 A and 8a 2 A a t M = m2M.

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.

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.

This paper replies to Nanay’s response to my recent paper. My suggestions are the following. First, “should” or “ought” does not need to be deontic. Second, etiological theories of function, like provability logic, do not need to attribute modal force to their explanans. Third, the explanans of the homological account of trait type individuation does not appeal to a trait’s etiological function, that is, what a trait should or ought to do. Finally, my reference to Cummins’s notion of function was (...) intended to note that the homological account is permitted to use this non-etiological notion of function. (shrink)

BackgroundThis essay provides an ethical and conceptual argument for the use of informed consent prior to the diagnosis of brain death. It is meant to enable the family to make critical end-of-life decisions, particularly withdrawal of life support system and organ donation, before brain death is diagnosed, as opposed to the current practice of making such decisions after the diagnosis of death. The recent tragic case of a 13-year-old brain-dead patient in California who was maintained on a ventilator for over (...) 2 years illustrates how such a consent would have made a crucial difference.MethodsConceptual, philosophical, and ethical analysis.ResultsI first consider a conceptual justification for the use of consent for certain non-beneficial and unwanted medical diagnoses. I suggest that the diagnosis of brain death falls into this category for some patients. Because the diagnostic process of brain death lacks the transparency of traditional death determination, has a unique epistemic structure and a complex risk-benefit profile which differs markedly from case to case, and presents conflicts of interest for physicians and society, I argue that pre-diagnostic counseling and informed consent should be part of the diagnostic process. This approach can be termed as “allow cardiac death”, whose parallel logic with “allow natural death” is discussed. I also discuss potential negative impacts on organ donation and health care cost from this proposal and offer possible mitigation. I show that the pre-diagnostic counseling can improve the possibility for well-thought-out decisions regarding organ donation and terminating life-support system in cases of hopeless prognosis. This approach differs conceptually from the pluralism of the definition of death, such as those in New Jersey and Japan, and it upholds the Uniform Determination of Death Act.ConclusionsMy intention is not to provide an instant panacea for the ongoing impasse of the brain death debate, but to point to a novel conceptual ground for a more pragmatic, and more patient- and family-centered approach. By enabling the family to consent to or decline the diagnostic process of brain death, but not to choose the definition of death, it upholds the current legal definition of death. (shrink)

Nakamura proposed two three-valued temporal logics. We present two extended Gentzen-type formulations of these logics. Then we prove the soundness as well as the completeness theorem.

We prove the strong normalization theorem for the natural deduction system for the constructive arithmetic TRDB (the system with Definition by Transfinite Recursion and Bar induction), which was introduced by Yasugi and Hayashi. We also establish the consistency of this system, applying the strong normalization theorem.

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.

This chapter traces the evolution of Japan's systems of household and land registration from c.1600 to the period of early Meiji reforms in the 1870s and 1880s, with due attention to the distinction between a system designed by the state and local forms of registration practice. In the section on the pre-Meiji period, one such local practice of having people ‘disowned’ and its consequence — registerlessness — is examined. The section on the Meiji reforms and the section that follows turn (...) to the issue of continuity and discontinuity, and the question of whether any progress was made by those reforms. In order to illustrate the actual changes that took place at the local level, the chapter begins with an eighteenth-century story about a peasant woman and ends with a case of a family dispute that another village woman brought before the court some 120 years later.
