What is ethics in the contemporary world? What is the need of defining ethics and, secondly, defining it in contemporary context? The meaning of ethics is so ambiguous to nonphilosophical academicians, corporate world, and others who look to the meaning in the branch of Philosophy called Ethics. At the end of endless debates, if the purpose of getting a definition is done, it is clarity in thinking in defining ethics which would happen. This may lead to clarity in the study (...) of ethics. And why should one study ethics at all? Ethics is interwoven at various levels in our life. The same individual is often in an obligation to face ethics at different levels like home, office, society, etc., or different ethical obligations. With a number of normative theories, the individual mind would be indefinite as to which one to follow. Is it just one theory alone which can be resorted to in an ethical dilemma or a combination of them? Are these theories practical also? Or are they just theories per se? To clear this ambiguity and in order to define ethics, the discussion of the meaning of ethics is important. This paper answers the above questions and throws light on the enquiry. This study hence is an exploratory one. Since the word ethics is interwoven with morality, it is worthwhile to define the word moral. (shrink)

_Despite advances in standard of living of the population, the condition of widows and divorced women remains deplorable in society. The situation is worse in developing nations with their unique social, cultural and economic milieu, which at times ignores the basic human rights of this vulnerable section of society. A gap exists in life expectancies of men and women in both developing and developed nations. This, coupled with greater remarriage rates in men, ensures that the number of widows continues to (...) exceed that of widowers. Moreover, with women becoming more educated, economically independent and aware of their rights, divorce rates are increasing along with associated psychological ramifications. The fact that widowed/divorced women suffer from varying psychological stressors is often ignored. It has been concluded in various studies that such stressors could be harbingers of psychiatric illnesses (e.g., depression, anxiety, substance dependence), and hence should be taken into account by treating physicians, social workers and others who come to the aid of such women. A change in mindset of the society is required before these women get their rightful place, for which a strong will is needed in the minds of the people, and in law-governing bodies._. (shrink)

The two parameters of leaf dimension namely, length and width, show inverse correlation with the third parameter, the thickness. A thermal diffusion model is proposed which explains the inverse relationship between these and envisages that while leaf length and width are directly influenced by the microclimate the thickness is affected by the microclimate through endoclimate and energy balance in the leaves. The significance of the model is discussed in the light of its importance in assessing the survival range of plant (...) species along the altitudinal gradient. (shrink)

Individuals with agrammatic Broca's aphasia experience difficulty when processing reversible non-canonical sentences. Different accounts have been proposed to explain this phenomenon. The Trace Deletion account attributes this deficit to an impairment in syntactic representations, whereas others propose that the underlying structural representations are unimpaired, but sentence comprehension is affected by processing deficits, such as slow lexical activation, reduction in memory resources, slowed processing and/or intermittent deficiency, among others. We test the claims of two processing accounts, slowed processing and intermittent deficiency, (...) and two versions of the Trace Deletion Hypothesis, in a computational framework for sentence processing implemented in ACT-R. The assumption of slowed processing is operationalized as slow procedural memory, so that each processing action is performed slower than normal, and intermittent deficiency as extra noise in the procedural memory, so that the parsing steps are more noisy than normal. We operationalize the TDH as an absence of trace information in the parse tree. To test the predictions of the models implementing these theories, we use the data from a German sentence—picture matching study reported in Hanne, Sekerina, Vasishth, Burchert, and De Bleser. The data consist of offline and online measures. From among the models considered, the model assuming that both slowed processing and intermittent deficiency are present emerges as the best model of sentence processing difficulty in aphasia. The modeling of individual differences suggests that, if we assume that patients have both slowed processing and intermittent deficiency, they have them in differing degrees. (shrink)

Structural biology has experienced several transformative technological advances in recent years. These include: development of extremely bright X-ray sources and the use of electrons to extend protein crystallography to ever decreasing crystal sizes; and an increase in the resolution attainable by cryo-electron microscopy. Here we discuss the use of these techniques in general terms and highlight their application for biological filament systems, an area that is severely underrepresented in atomic resolution structures. We assemble a model of a capped tropomyosin-actin minifilament (...) to demonstrate the utility of combining structures determined by different techniques. Finally, we survey the methods that attempt to transform high resolution structural biology into more physiological environments, such as the cell. Together these techniques promise a compelling decade for structural biology and, more importantly, they will provide exciting discoveries in understanding the designs and purposes of biological machines. Structural biology is undergoing technological advancements that now reveal the structures of previously inaccessible biological machines. Microfocus synchrotron beamlines, X-ray free electron lasers, and MicroED cope with vanishingly small crystals, while cryo-electron microscopy targets single molecules at near atomic resolution. These advances promise an exciting decade for structural biology. (shrink)
