Understanding terrestrial carbon metabolism is critical because terrestrial ecosystems play a major role in the global carbon cycle. Furthermore, humans have severely disrupted the carbon cycle in ways that will alter the climate system and directly affect terrestrial metabolism. Changes in terrestrial metabolism may well be as important an indicator of global change as the changing temperature signal. Improving our understanding of the carbon cycle at various spatial and temporal scales will require the integration of multiple, complementary and independent methods (...) that are used by different research communities. Tools such as air sampling networks, inverse numerical methods, and satellite data allow us to study the strength and location of the global- and continental-scale carbon sources and sinks. Bottom-up studies provide estimates of carbon fluxes at finer spatial scales and examine the mechanisms that control fluxes at the ecosystem, landscape, and regional scales. Bottom-up approaches include comparative and process studies that provide the necessary mechanistic information to develop and validate terrestrial biospheric models. An iteration and reiteration of top-down and bottom-up approaches will be necessary to help constrain measurements at various scales. We propose a major international effort to coordinate and lead research programs of global scope of the carbon cycle. (shrink)

Futile medical interventions have virtually no chance of success. Doctors might perform such procedures because of pressure from families or patients. The doctor might also have an ulterior motive of gain or prefer to do it rather than take time to communicate with the patient about a poor prognosis. Established ways to communicate bad news to patients are not always used by managing physicians with time constraints. The SPIKES protocol method is outlined to assist in sensitive communication where further intervention (...) is futile. This review primarily explores various aspects of medical futility. It also explores strategies for effectively communicating with patients and their families regarding futility interventions. A side-effect of futile interventions is burnout in doctors and other health practitioners (HPs). The complex relationship between futility and burnout is described. (shrink)

Atheism has been on the rise in the West for several decades, but its roots, including those belonging to secularism, agnosticism, and freethought, run deep in Western history, philosophy, and thought. Drawing on a multitude of sources from a number of disciplines, S. T. Joshi outlines the natural origins of religious belief in primitive times and charts the slow development of secular accounts of natural phenomena in the Greco-Roman world. Adopting the " Christ myth" theory, he surveys the emergence of (...) a new faith- Christianity- that grew out of Judaism and explores its evolution through the medieval period. He then examines the increasing schisms within the church and conflicts between religious and political entities that caused a fracturing of the monolith of Christianity and the birth of the Renaissance, which not only brought to light the literary glories of the Greco-Roman world but also led to a scientific resurgence and the development of a secular view of the cosmos. By the end of the sixteenth century, as he concludes, the stage was set for the emergence of a worldview free of religion. (shrink)

In his article “Explanation Sketches” [3], Fred Newman argues that Scriven is mistaken in his interpretation of Hempel's notion of explanation sketch. According to Scriven, to complete an explanation is to fill in further initial conditions so that the explanandum of the sketch would be entailed by the new enlarged set of initial conditions. The point may be alternatively put by saying that according to Scriven to have a complete explanation is to have a covering-law which connects initial conditions with (...) the explanandum of the original sketch. Now Scriven's point against the deductive theory as applied to History is just that very often when we try to complete a given explanation sketch, we only succeed in unearthing a law which is either false or else trivial. Newman, however, contends that this is an excusable but, nevertheless, unsympathetic way of interpreting Hempel. He suggests an alternative account to the effect that to complete an explanation we need not necessarily produce a covering-law connecting initial conditions with the explanandum; all we need to do is to mention other initial conditions and certain laws which need not necessarily contain mention of the explanandum of the sketch. As he himself puts the point: “However, generously interpreted, when Hempel speaks of a sketch vaguely indicating laws we may take him as merely suggesting that some laws are vaguely indicated which would make up the explanans of an explanation of the event in question—not necessarily in the terms which describe the event in the sketch's explanandum.”.

Much attention is given to education in philosophy in the USSR, in which the study of dialectical and historical materialism occupies a special place. The practical achievements involved in the transformation of society, together with the advance of the natural and social sciences, have demonstrated most clearly the great strength of dialectical materialism as the scientific world view of the working people and as the philosophical foundation of their practical activity. It is therefore no accident that philosophy has an immense (...) attraction for people in our country. (shrink)

The problem of contradictions in the life of society has to do both with the theory of dialectics and with sociological research. Although it is impossible to separate these two aspects, the present paper will give major attention to the former aspect, that is, analysis of the specific manifestations of the universal dialectical law of the unity and struggle of opposites under the conditions of a socialist society.

IN the Sixteenth Satire, the first topic Juvenal takes up in detail is the impossibility of obtaining satisfactory legal redress from the praetorians. The account has two divisions: you will have a bad time yourself in the military court, and what friend will come to support you ?

Zeno's famous paradox of the flying arrow, and the statements made in efforts to solve it by Hegel and Engels to the effect that a moving body is, at a given instant, both in and not in a given place, reveal, on the one hand, the objective contradictoriness of motion and, on the other, the difficulty of explaining it within the framework and method of formal logic. The elevation of the laws of formal logic to an absolute, and the exaggeration (...) of its role have led certain writers to deny the truth of Hegel's and Engels' statement. It was shown that no body can simultaneously be and not be in a given place, and that, in describing motion, one should, instead of employing this mode of expression, merely say that the body is shifting, and successively passes one point after another. This passage is motion as an objectively non-contradictory process. (shrink)

Point-of-care testing (POCT) is a sensitive, specific and rapid form of testing for the presence of HIV antibodies. Post-exposure prophylaxis for HIV infection can reduce seroconversion rates by up to 80%. Needlestick injuries are the second commonest cause of occupational injury in the NHS and 20% of these occur during operations. In the NHS, in order to protect staff and patients from the risk of bloodborne viruses such as HIV, it is mandatory to report such injuries; however, numerous studies have (...) shown that many groups, particularly doctors, are reluctant to do so. This article outlines the arguments for and against the introduction of preoperatively seeking consent from patients to have their blood tested for HIV via POCT in order to improve the reporting rates of needlestick injuries incurred during surgery and to protect staff from infection.

This research examines the extent to which similarities and differences exist in the codes of professional conduct of certified (chartered) accountants across the following countries: the United States, Taiwan, South Korea, Malaysia, Ontario (Canada), Australia, India, and Hong Kong. These eight countries exemplify some of the diversity in economic, political, legal, and cultural environments in which public accountants practice. The professional codes of ethics establish the ethical boundary parameters within which professional accountants must operate and they are a function of (...) these environments.The results of the study reveal that commonalities exist on some ethical rules indicating that some rules are indeed "culture free". Cross-country variations, however, exist as to the specificity and elaborateness of the rules. Such variations can be attributed to cultural and legal differences, as well as the length of time each professional organization has been in existence. An understanding of the similarities and differences in the codes is important to individuals who may work in these countries. Professional accountants involved in international business must understand the implications of the decisions they make in light of the ethical codes and moral values of their counterparts in foreign countries. After a discussion of the similarities and differences in the codes, the implications of these comparisons for accounting practice are discussed. (shrink)
