In his 1987 book _Conditionals, Frank Jackson presents an argument to the effect that the indicative conditionals of natural language have the same truth conditions as the material conditional of truth-functional logic. This Jackson refers to as the "paradox of indicative conditionals." I offer a solution to this paradox by arguing that some conditionals that appear to be in the indicative mood are actually subjunctives, to which the paradox does not apply. I support this proposed solution with some historical observations (...) on the evolution of the English verb phrase. (edited). (shrink)

This study examined the relationship between unethical employee behavior and the dimensions of the Ethical Climate Questionnaire (ECQ). In order to explore the relationship between the dimensions of the ECQ and unethical behavior, the factor structure of five previously identified empirical models and the hypothesized nine-dimension model for the ECQ was tested with a confirmatory factor analysis. The analysis revealed that the hypothesized nine-dimension model provided as good or even better fit to the data than the five empirically derived models. (...) Therefore, the nine-dimensional model was used to examine the criterion-related validity of the ECQ. The results demonstrated that the nine ethical climate dimensions were correlated with some of the unethical behaviors examined in this study, but not others. However, the results clearly demonstrated that most of the ethical climate dimensions were significantly related to an aggregate measure of unethical behavior. It was suggested that these results might account for the differences in previous studies on the criterion-related validity of the ECQ. The results also replicated a previous report that the association between unethical behavior and ethical climate is stronger in organizations that do not have a code of ethics. Finally, a difference was observed in the ethical climates for organizations with a code of ethics and organizations without a code of ethics. (shrink)

Case 1 reminds us that patients have duties too, while case 2 presents an instance of justified withholding of informationHow refreshing to read these two cases! No conjoined twins, fantastical chimeras, or other incredible scenarios at the fringes of medical reality. Each case highlights the practical and theoretical difficulties that doctors face in their everyday practice.Case 1: In case 1, the patient, who had declined an HIV test, changed his mind and requested an HIV test on the request form without (...) informing the doctor. The pathologist performed the tests and returned the results to the unsuspecting doctor, who duly investigated the matter. The doctor’s anxiety at the situation, as well as the worries of the entire practice and pathology laboratory, must have been deeply unpleasant. Thus the patient, no doubt unintentionally, caused much distress by requesting the HIV test. He was, at the very least, guilty of a lack of foresight and consideration. As a minimum, he should have informed the doctor of his last minute alteration. This would have enabled the doctor to discuss the implications of the test, to organise appropriate counselling, and, most importantly, to receive the results in full knowledge of the situation.As Dr Fraser points out, the experience of case 1 reinforces the importance of taking good medical notes. Even if the patient’s refusal had been documented in the notes, however, this would not have prevented him from requesting the HIV test, and indeed other tests, on the blood form. Pharmacists may still occasionally be faced with situations when they are unsure whether the doctor prescribed 10 capsules of a drug, or 110 capsules, as the patient may have added a “1” in front of the doctor’s original prescription. Similarly, how …. (shrink)

The medical profession’s role should be limited to advice and informationThe medical establishment’s desire to interfere with the autonomous wishes of boxers seems at odds with the principle of respect for autonomy prevalent in contemporary biomedical practice. I argue that the role of the medical profession in boxing should be solely an advisory and informational one. In addition, the distinctions made between boxing and other high risk sports often rely on an insufficient knowledge of the sport. This leads to misdirected (...) criticisms and excessive emphasis on the colourful discourse of boxing, as opposed to the practice of boxing itself. Dr Herrera’s claim in his article that boxing differs from other sports in the acceptability of its acts outside the realm of sport is refuted.1 The importance of consent as a legitimising factor is highlighted, and a number of possible solutions to improve safety within the sport are tentatively suggested.In the United Kingdom, a competent adult may legally refuse medical treatment, irrespective of the severity of his condition or the validity of his reasons. With the pre-eminence of an autonomy based model of bioethics, respecting a patient’s wishes forms an integral part of acting in his best interests. It is puzzling, then, to find that the Australian Medical Association have called for a ban on boxing on the grounds that the activity is excessively hazardous to the health of boxers. The often mentioned principle of respect for autonomy is abandoned once the person drops the privileged title of “patient”. This suggests that being a patient …. (shrink)

The public revelation in 2003 that medical students perform intimate examinations without patient consent has engendered much debate in the press and scientific journals. Using this case as a springboard for discussion, I will argue that medical schools should encourage students to raise their ethical concerns and call for a change of policy making it easier for students to do so. I will also address the question of medical students’ moral obligations towards their patients, and conclude that medical students ought (...) to express their discontent when faced with unethical practices or attitudes.In early January 2003, a study appeared in the British Medical Journal revealing that nearly a quarter of rectal and vaginal examinations on anaesthetised patients were performed by medical students without patient consent.1 Although the study did not generate the firestorm of controversy many expected, it engendered much discussion on ethical issues surrounding informed consent and patient autonomy, as well as stressing the need for greater ethics training for medical students. As an ethical problem, however, the case of intimate examinations is, to my mind, relatively uninteresting. If we agree that it is wrong for doctors to perform a vaginal examination on a conscious person without their consent, then it follows that it will still be …. (shrink)

This work is a volume in the series Ancient Commentators on Aristotle, edited by Richard Sorabji. The aim of the series is to make the Greek commentaries available in English. Konstan does an admirable job of this. The translation is extremely careful, clear, and readable. Konstan succeeds in staying close to the text without sacrificing intelligibility. Whenever necessary, he inserts words or phrases in brackets to complete the sense of an accurately translated passage. Konstan also makes use of brackets to (...) give precise citations to fill out Simplicius' references. The footnotes, too, are excellent. There the reader finds information about deviations from Diels's text, about alternative readings, and explanations of renderings into English that might be controversial. In the introduction, Sorabji gives a thumbnail sketch of the philosophical issues raised by Physics 6. Several useful documents are appended to the commentary, namely, a list of all departures from Diels's text, an appendix written by the editor providing a brief survey of the ancient Greek commentators, and a list of the philosophers cited by Simplicius with a onesentence description of each.

Theoretical and experimental studies on prey–predator systems where predator is supplied with alternate sources of food have received significant attention over the years due to their relevance in achieving biological conservation and biological control. Some of the outcomes of these studies suggest that with appropriate quality and quantity of additional food, the system can be steered towards any desired state eventually with time. One of the limitations of previous studies is that the desired state is reached asymptotically, which makes the (...) outcomes not easily applicable in practical scenarios. To overcome this limitation, in this work, we formulate and study optimal control problems to achieve the desired outcomes in minimum (finite) time. We consider two different models of additional food provided prey–predator systems involving Holling type IV functional response (with inhibitory effect of prey). In the first scenario, additional food is incorporated implicitly into the predator’s functional response with a possibility of achieving biological conservation through co-existence of species and biological control by maintaining prey at a level that is least harmful to the system. In the second, the effect of additional food is incorporated explicitly into the predator’s compartment with the goal of pest management by maintaining prey density at a very minimal damaging level. For both cases, appropriate optimal control strategies are derived and the theoretical findings are illustrated by numerical simulations. We also discuss the ecological significance of the theoretical findings for both models. (shrink)

In the de Anima, Aristotle outlines a theory of perception. In de Anima II, 5-12, he considers the basic kinds of sensory perception — seeing, hearing, touching, tasting and smelling. He uses a few basic elements, viz., the five senses and their proper, common and incidental objects, and a few explanatory principles to explain sensory perception. In de Anima III, 1–2, Aristotle turns to apperception, viz. perceptual selfawareness. He considers several basic cases of apperception – the selfconscious awareness of occurrent (...) perceptions and the awareness that the objects of different senses are different. (shrink)

In the work of Nietzsche, sacrifice can only sacrifice itself over and over (in an eternal return of the same) because what it seeks to overcome (the nihilistic revelation of truth that sublates sacrifice's negation) makes this sacrifice of itself both necessary and useless. The truth is eternally postponed in a necessary sacrificial gesture that can only sacrifice itself, thereby rendering itself useless. In the attempt to step beyond nihilism, that is, in the attempt to negate (or sacrifice) nihilism, one (...) repeats the negation characteristic of nihilism. One becomes inextricably implicated in the move of nihilistic sacrifice. The sacrifice of the sacrifice characteristic of nihilism, that is, the sacrifice of sacrifice, can only take place as (perform itself as) the impossibility (or eternally postponed possibility) of its realization. One, therefore, produces or performs an interminable step/not beyond, an incessant step beyond that eternally returns. (shrink)

A study was carried out from October, 2020 to September, 2021to investigate the diversity of fishes and the conservation status of Chittaura Jheel (Bahraich), Uttar Pradesh. During the study period, 38 fish species belonging to 28 genera, 14 families and 7 orders have been identified. The order Cypriniformes was found the dominated order with 15 species(39.47%) followed by Siluriformes 10 species (26.31%), Perciformes 4 species (10.52%), Ophiocephaliformes 4 species (10.52%), Synbranchiformes2 species (5.26%), Osteoglossiformes 2 species (5.26%) and Clupiformes 1 species (...) (2.63 %), The present investigation showed that the wetland, Chittaura Jheel possesses rich fish biodiversity but proper conservation measures are required to maintain sustainability and richness of the fish species diversity of that wetland of U.P. According to IUCN, 30 were enlisted as Least Concern (LC), 2 species as near endangered (NE), 3 species as near threatened (NT), 2 listed as Endangered (EN) and 1 species was listed as Vulnerable (VU). There is a need of conservation of fish diversity of this natural wetland. The pressure is increasing day by day due to increasing population, leading to loss of fish diversity hence identifying the problem and making a better management plan is the way for conservation of the fish diversity of the Chittaura Jheel, a wetland of Bahraich district of Uttar Pradesh.

Although telephone consultations are widely used in the delivery of healthcare, they are vulnerable to breaches of patient confidentiality. Current guidelines on telephone consultations do not address adequately the issue of confidentiality. In this paper, we propose a solution to the problem: a password system to control access to patient information. Authorised persons will be offered the option of selecting a password which they will use to validate their request for information over the telephone. This simple yet stringent method of (...) access control should improve security while allowing the continuing evolution of telephone consultations. (shrink)

Context: Few professional philosophers have addressed in any detail radical constructivism, but have focused instead on the related assumptions and limitations of postmodern epistemology, various anti-realisms, and subjective relativism. Problem: In an attempt to supply a philosophical answer to the guest editors’ question, “Why isn’t everyone a radical constructivist?” I address the realist (hence non-radical) implications of the theory’s invocation of “others” as an invariable, observer-independent, “external” constraint. Results: I argue that constructivists cannot consistently defend a radically subjectivist theory of (...) knowing while remaining entirely agnostic about the nature and existence of the larger world (including independent others). That is, any non-solipsistic account of human experience must explicitly acknowledge its extra-subjective, ontological dimension. Implications: It follows that no pedagogical, social, philosophical, or commonsensical insight associated with so-called “trivial” or “social” constructivism survives or receives any support from the move to radical constructivism.

Alzheimer's disease is characterized by formation of neuritic plaque primarily composed of a small filamentous protein called amyloid-beta peptide . The rate-limiting step in the production of Abeta is the processing of Abeta precursor protein by beta-site APP-cleaving enzyme . Hence, BACE1 activity plausibly plays a rate-limiting role in the generation of potentially toxic Abeta within brain and the development of AD, thereby making it an interesting drug target. A phase II trial of the promising LY2886721 inhibitor of BACE1 was (...) suspended in June 2013 by Eli Lilly and Co., due to possible liver toxicity. This outcome was apparently a surprise to the study's team, particularly since BACE1 knockout mice and mice treated with the drug did not show such liver toxicity. Lilly proposed that the problem was not due to LY2886721 anti-BACE1 activity. We offer an alternative hypothesis, whereby anti-BACE1 activity may induce apparent hepatotoxicity through inhibiting BACE1's processing of beta-galactoside alpha-2,6-sialyltransferase I . In knockout mice, paralogues, such as BACE2 or cathepsin D, could partially compensate. Furthermore, the short duration of animal studies and short lifespan of study animals could mask effects that would require several decades to accumulate in humans. Inhibition of hepatic BACE1 activity in middle-aged humans would produce effects not detectable in mice. We present a testable model to explain the off-target effects of LY2886721 and highlight more broadly that so-called off-target drug effects might actually represent off-site effects that are not necessarily off-target. Consideration of this concept in forthcoming drug design, screening, and testing programs may prevent such failures in the future. (shrink)

Scientific developments of the last 20 years have made the transplantation of cadaveric solid organs a viable and expected treatment alternative for patients suffering from various forms of End Stage Organ Disease. Of the number of organs that could be utilized for this, only a small percentage of them are actually made available. North American legislation explicitly categorizes the transfer of cadaveric organs as an anatomical or tissue “gift”. The concept of the gift is mediated by transculturally consistent unwritten, but (...) powerfully felt, rules of conduct. Among the most profound elements of the concept is the obligatory gift-exchange which is central to the gift-relationship. Obviously, neither of these are permitted by the organ transplant scenario. As a result, dissonance is created within the thought process of the individual which cannot be easily resolved, paralyzing many into inaction. We maintain that the present legal framework, designed to facilitate the transfer of organs, clashes with the human phenomenon of giving, and may actually prevent organs from being made available. In a search for a solution to this gift-relationship dilemma, giving organs is contrasted with taking organs as a basis upon which to ground ethically sound public policy. Liberty-limiting principles and the concept of harm are considered within this context. (shrink)

It is conventional to try to arrive at the Boltzmann principle and the Second Law starting with the laws of dynamics at the microscopic level. In this article the opposite view is presented: Starting with the Second Law, microscopic properties are derived. A classical result of Wien is developed into a general theorem, and the possibility of deriving the Boltzmann principle as a consequence of Carnot's theorem is discussed.

In 1982, Jonsen, Siegler and Winslade published Clinical Ethics, in which they described the “four quadrants” approach, a new method of analysing clinical ethics cases. Although the book is now in its 6th edition, a literature search has revealed only one academic paper demonstrating the method at work. This paper is an attempt to start filling this gap. As a way of describing and testing the approach, I apply the four quadrants method to a detailed clinical ethics case. The analysis (...) is interspersed with reflections on the method itself. It is hoped that this experiment will encourage ethicists and clinicians to devote more attention to this neglected approach. (shrink)
