The literature on public perceptions of, and attitudes towards, nanotechnology used in the agrifood sector is reviewed. Research into consumer perceptions and attitudes has focused on general applications of nanotechnology, rather than within the agrifood sector. Perceptions of risk and benefit associated with different applications of nanotechnology, including agrifood applications, shape consumer attitudes, and acceptance, together with ethical concerns related to environmental impact or animal welfare. Attitudes are currently moderately positive across all areas of application. The occurrence of a negative (...) or positive incident in the agri-food sector may crystallise consumer views regarding acceptance or rejection of nanotechnology products. •Acceptance of agrifood nanotechnology based on perceptions of risk, benefit and ethics.•Attitudes towards nanotechnology in general are currently moderately positive.•Occurrence of a major nanotechnology-related "event" may crystallise consumer attitude.

Acute exercise consistently benefits both emotion and cognition, particularly cognitive control. We evaluated acute endurance exercise influences on emotion, domain-general cognitive control, and the cognitive control of emotion, specifically cognitive reappraisal. Thirty-six endurance runners, defined as running at least 30 miles per week with one weekly run of at least 9 miles (21 female, age 18-30 years) participated. In a repeated measures design, participants walked at 57% age-adjusted maximum heart rate (HRmax) (range 51-63%) and ran at 70% HRmax (range 64-76%) (...) for 90 minutes on two separate days. Participants completed measures of emotional state and the Stroop test of domain-general cognitive control before, every 30 minutes during, and 30 minutes after exercise. Participants also completed a cognitive reappraisal task after exercise. Functional near-infrared spectroscopy tracked changes in oxygenated and deoxygenated hemoglobin levels in the prefrontal cortex (PFC). Endurance exercise elevated positive emotion and cognitive reappraisal success. Endurance exercise reduced Stroop response time and test-evoked PFC oxygenation during exercise. Results suggest that even at relatively moderate intensities, endurance athletes benefit emotionally from running both during and after exercise, and task-related prefrontal cortex oxygenation reductions do not appear to hinder prefrontal-dependent cognitive control.

Les Theoremata d'esse et essentia (ca 1278-1285), qui, en depit d'une edition critique deja ancienne (Hocedez, 1930), n'avaient pas encore ete traduits integralement en francais a ce jour, apparaissent comme l'uvre majeure pour bien saisir la genese doctrinale et conceptuelle de la theorie de la distinction reelle. Peu de temps avant les Questions disputees sur l'etre et l'essence (1286-1287), qui sont au cur du debat entre Gilles de Rome (ca 1245-1316), partisan d'une distinction reelle entre l'etre et l'essence, et Henri (...) de Gand (ca 1217-1293), promoteur d'une theorie de la distinction " intentionnelle ", les Theoremes apparaissent comme un essai de synthese, dans lequel le maitre augustin donne un expose d'ensemble des arguments qui le conduisent a faire de l'etre une res (" chose " au sens de " realite ") a part entiere. Dans ces conditions, les disciples de Thomas d'Aquin (ca 1224-1274) n'ont pas manque de voir, en Gilles, l'un des partisans d'une these qu'ils revendiquaient comme un heritage de l'Aquinate. Les Theoremes revelent cependant une pensee incontestablement personnelle, et manifestent le caractere resolument original de Gilles de Rome, metaphysicien incontournable du XIIIe siecle finissant.

The word ‘existentialism’ has become something of a catchword in religious circles today, and one suspects that it is sometimes a substitute rather than a medium for thought. Most theological teachers must from time to time have received from a pupil an essay in which the words ‘existential’, ‘existentially’ and ‘existentialism’ appear to have been sprinkled from a pepper-pot over an exposition whose meaning would remain unchanged if these words were excised altogether. Nevertheless, usum non tollit abusus, and the following (...) rather unsystematic remarks may perhaps be of some help in elucidating and evaluating a mode of thought and expression which has attracted the interest of some of the more profound, as well as of some of the more superficial, theological and philosophical writers of the present day.

Research Ethics Committees (RECs) are frequently a focus of complaints from researchers, but evidence about the operation and decisions of RECs tends to be anecdotal. We conducted a systematic study to identify and compare the ethical issues raised in 54 letters to researchers about the same 18 applications submitted to three RECs over one year. The most common type of ethical trouble identified in REC letters related to informed consent, followed by scientific design and conduct, care and protection of research (...) participants, confidentiality, recruitment and documentation. Community considerations were least frequently raised. There was evidence of variability in the ethical troubles identified and the remedies recommended. This analysis suggests that some principles may be more institutionalized than others, and offers some evidence of inconsistency between RECs. Inconsistency is often treated as evidence of incompetence and caprice, but a more sophisticated understanding of the role of RECs and their functioning is required. (shrink)

Medical educators invoke professionalism as a core competency in curricula. This paper criticizes classic definitions. It also identifies some negative traits of medicine as a profession. The call to professionalism is naive nostalgia. Straightforward didactics in professionalism cannot do the desired work in medical education. The most we can say is that students should adopt the good aspects of professionalism and the profession should stop being some of what it has been. This is a platitude. If the notion is to (...) be more than shallow, each student and practitioner will have to engage in much dialogue, reflection and refinement over many years. (shrink)
