In view of the confusion about the use of the term ‘population’ in biology, an analysis has been made of the use of the concept of population in biology. Origin and development, logic and epistemology of the population-concept have been investigated for that purpose. It appears that several concepts of population coexist in biology. The term ‘population’ is used for all these concepts, so it is not amazing that confusion has arisen. This confusion is the more dangerous, since ‘population’ plays (...) an important part in the theory of evolution. A modus has been suggested to diminish this confusion by defining ‘population’ in a very wide sense of the term and by proposing a ‘deme’—terminology to specify the various special concepts of population.

The structure of Psalm 2 is based on direct speeches in the text. These direct speeches characterise the communication that takes place in the text. The text-immanent author addresses the text-immanent reader with a question in the first line and with a makarismos in the last line. The direct speeches of the characters enable the text-immanent reader to undergo a development in his striving towards the beatitude. In this development, the ‘now’ of the birth of the Anointed One / Son (...) is re-enacted in the reading moment of the text-immanent reader. The reception of Psalm 2 makes clear that Hebrews and the Christmas liturgy re-use the text, while retaining this re-enactment character. (shrink)

Background and aim With the increasing interest in lifestyle, health and consequences of unhealthy lifestyles for the healthcare system, a new kind of solidarity is gaining importance: lifestyle solidarity. While it might not seem fair to let other people pay for the costs arising from an unhealthy lifestyle, it does not seem fair either to punish people for their lifestyle. However, it is not clear how solidarity is assessed by people, when considering disease risks or lifestyle risks. The aim of (...) this study was to investigate the degree of solidarity with lifestyle as well as with other factors that are related to health outcomes—for example, old age—and the relation between this degree of solidarity and various characteristics. Methods This cross-sectional study is part of the Dutch longitudinal SMILE study. Data on the degree of solidarity with different lifestyles and old age, and the relation between the degree of solidarity and various demographic and other variables were obtained in a questionnaire survey. Results Solidarity with smokers and overweight people was moderate, as was solidarity with older people. Respondents were ambivalent about athletes. Respondents who were younger, male and highly educated, and those with a healthy lifestyle, a small social network, high quality of life and an internal locus of control, showed low solidarity. Conclusions Solidarity with an unhealthy lifestyle and old age is moderate and the degree of solidarity varies among the different subgroups. (shrink)

Peer review of grant applications, it has been suggested, might be distorted by what is popularly termed old boyism, cronyism, or particularism. We argue that the existing debate emphasizes the more uninteresting aspects of the peer review system and that the operation of old boyism, as currently understood would have little effect on the overall direction of science. We identify a phenomenon of cognitive particularism, which we consider to be more important than the institutional cronyism analyzed in previous studies. We (...) illustrate with material drawn from observation of grant-awarding commit tees of the Science and Engineering Research CounciL In the concluding discussion, we explore some of the possible implications for the peer review system.

OBJECTIVES: To determine the epidemiology and the underlying pathological conditions of natural deaths among motor vehicle drivers. Sudden death while driving may cause damage to properties, other vehicles or road users. Although the Medical Commission on Accident Prevention recommended restrictions to drivers at risk of sudden death due to their medical conditions, these restrictions are useless if they do not result in greater safety to the public. DESIGN: A retrospective study of natural deaths of motor vehicle drivers. SETTING: Natural deaths (...) of motor vehicle drivers reported to the coroner for Birmingham and Solihull. SUBJECTS: 86 consecutive natural deaths of motor vehicle drivers in a five-year period between 1984 and 1988. RESULTS: Of the 86 fatalities reviewed, 80 (93%) sudden deaths were caused by ischaemic heart disease. Fifty vehicles were involved in collision with 32 properties, 20 other vehicles and six pedestrians. Fifty-one out of 80 cardiac deaths had past cardiac history and three had reported chest pain prior to the sudden death. CONCLUSION: An applied normative ethical assessment based on the basic moral principles of autonomy, justice, beneficence and non-maleficence are discussed. We conclude that medical screening of drivers has little benefit for the drivers or other persons. (shrink)

There are a number of problematic features within the current treatment of time in physical theories, including the “timelessness” of the Universe as encapsulated by the Wheeler–DeWitt equation. This paper considers one particular investigation into resolving this issue; a conditional probability interpretation that was first proposed by Page and Wooters. Those authors addressed the apparent timelessness by subdividing a faux Universe into two entangled parts, “the clock” and “the remainder of the Universe”, and then synchronizing the effective dynamics of the (...) two subsystems by way of conditional probabilities. The current treatment focuses on the possibility of using a realistic clock system; namely, a coherent-state description of a damped harmonic oscillator. This clock proves to be consistent with the conditional probability interpretation; in particular, a standard evolution operator is identified with the position of the clock playing the role of time for the rest of the Universe. Restrictions on the damping factor are determined and, perhaps contrary to expectations, the optimal choice of clock is not necessarily one of minimal damping. (shrink)

With this issue we initiate the policy of expanding the scope of Tulane Studies in Philosophy to include, in addition to the work of members of the department, contributions from philosophers who have earned advanced degrees from Tulane and who are now teaching in other colleges and universities. The Editor THE LOGIC OF OUR LANGUAGE ROBERT L. ARRINGTON Wittgenstein wrote in the Tractatus that "logic is not a body of doctrine, but a mirror-image of the world. " 1 In line (...) with his suggestion that a proposition is a 'picture', Wittgenstein argued that propositions 'show' the logical structure of the real. He was insistent, however, that "the apparent logical form of a proposition need not be its real one. " 2 As a result of this we can misunderstand the structure of fact. Philosophical problems arise just when "the logic of our language is mis understood. " 3 It is common knowledge that much of this view of logic was rejected by Wittgenstein himself in the Philosophical Investi gations. There we are told that language has no ideal or sublime 4 logic which mirrors the structure of the extra-linguistic world. Consequently, inferences from the structure of language to the structure of that extra-linguistic world are invalid. Reality can be 'cut up' in any of a number of ways by language. Wittgenstein adopted a view of philosophy which would render that discipline a non-explanatory, non-critical study of the multiple ways in which language can be used. (shrink)

Social media applications such as Twitter, YouTube and Facebook have attained huge popularity, with more than three billion people and organizations predicted to have a social networking account by 2015. Social media offers a rapid avenue of communication with the public and has potential benefits for communicable disease control and surveillance. However, its application in everyday public health practice raises a number of important issues around confidentiality and autonomy. We report here a case from local level health protection where the (...) friend of an individual with meningococcal septicaemia used a social networking site to notify potential contacts. (shrink)
