The transition from the Athenian Peripatos of Aristotle to the Alexandrian Museion of Callimachus has often attracted notice. So closely akin was the organization of scholarship in the two centres of learning, so definite was the personal connexion between the two, that it seemed possible to trace an uninterrupted line of succession from the older to the younger school. That Callimachus the scholar worked in the Aristotelian tradition appeared obvious: ‘he might be called a Peripatetic in the same sense as (...) his pupils, but with more justification’ (Wilamowitz,Hellenist. Dicht.i. 214). Regarding Callimachus the poet and literary critic the picture seemed less clear. The non-classical character of his poetry had often been emphasized, and cannot be overlooked. But quite recently an attempt has been made to turn Callimachus into an Aristotelian even by virtue of his literary criticism. The alleged harmony of this development rouses suspicion and calls for inquiry. In the following pages I have tried to collect and discuss what material I could find for the relation of Callimachus to Aristotle and his school. I hope to show that such influences as there were are of a different and more subtle nature, and that this poet, if any, was his own Longinus. (shrink)

Using multi–sources: archeaology, history, geography, anthropology, wildlife, zoology, biology, oral tradition and archival material, the article examines the history of the elephant in Ghana, highlighting the various methods employed in hunting as well as the cultural and economic use values of the elephant in Ghana.

In the present paper two kinds of quantum-theoretical states are considered: the “physical state” determined by a complete observation and the “intrinsic state” which comprises the values of the observed as well as the unobserved observables. It will be shown that the future values of all these observables are determined. Causality is therefore valid, though not verifiable.

We argue that developing a human ethics application is an effective method for refining the intent and design of research studies. Our study aimed to investigate the delivery of end-of-life and palliative care nursing to residents of an aged care unit in a Multi-purpose Service/centre in rural Victoria. We used the ethics application process as a strategy to focus the study, and to refine the data collection and analysis techniques. It is our contention that the process of completing the application (...) and gaining ethics approval is laborious; however, the intellectualising that occurs provides researchers with an opportunity to reflect upon and refine their studies, thus ensuring the ultimate success and timely completion of research investigations.

The book provides a practical guide to the application of Critical Realism (CR), an increasingly popular philosophy of social science, in empirical research projects. Each purpose-written chapter reviews major social science research methods and contains extended illustration of how to conduct inquiry using CR.

Magnetic resonance imaging (MRI) can provide a number of measurements relevant to sport-related concussion (SRC) symptoms; however, most studies to date have used a single MRI modality and whole-brain exploratory analyses in attempts to localize concussion injury. This has resulted in highly variable findings across studies due to wide ranging symptomology, severity and nature of injury within studies. A multimodal MRI, symptom-guided region-of-interest (ROI) approach is likely to yield more consistent results. The functions of the cerebellum and basal ganglia transcend (...) many common concussion symptoms, and thus these regions, plus the white matter tracts that connect or project from them, constitute plausible ROIs for MRI analysis. We performed diffusion tensor imaging (DTI), resting-state functional MRI, quantitative susceptibility mapping (QSM), and cerebral blood flow (CBF) imaging using arterial spin labeling (ASL), in youth aged 12-18 years following SRC, with a focus on the cerebellum, basal ganglia and white matter tracts. Compared to controls similar in age, sex and sport (N = 20), recent SRC youth (N = 29; MRI at 8 ± 3 days post injury) exhibited increased susceptibility in the cerebellum (p = 0.032), decreased functional connectivity between the caudate and each of the pallidum (p = 0.035) and thalamus (p = 0.021), and decreased diffusivity in the mid-posterior corpus callosum (p < 0.038); no changes were observed in recovered asymptomatic youth (N = 16; 41 ± 16 days post injury). For recent symptomatic-only SRC youth (N = 24), symptom severity was associated with increased susceptibility in the superior cerebellar peduncles (p = 0.011) and reduced activity in the cerebellum (p = 0.013). Fewer days between injury and MRI were associated with reduced cerebellar-parietal functional connectivity (p < 0.014), reduced activity of the pallidum (p = 0.002), increased CBF in the caudate (p = 0.005), and reduced diffusivity in the central corpus callosum (p < 0.05). Youth SRC is associated with acute cerebellar inflammation accompanied by reduced cerebellar activity and cerebellar-parietal connectivity, as well as structural changes of the middle regions of the corpus callosum accompanied by functional changes of the caudate, all of which resolve with recovery. Early MRI post-injury is important to establish objective MRI-based indicators for concussion diagnosis, recovery assessment and prediction of outcome. (shrink)

German educators have long been concerned with the didactics of scientific education. Shortly after the Humboldtian reforms of the early nineteenth century, university science professors realized that they had to rely on teachers in the Gymnasien for well-prepared students. By mid-century, these teachers responded with treatises on the pedagogy of scientific education, treatises whose ideas, when implemented, guaranteed scientifically literate students who would later lead Germany to her first place position in the scientific world by 1900. Now, in the twentieth (...) century, two special conditions have changed the sense in which students could and should be scientifically literate. Logical positivism and its heirs inaugurated rigidly exact methodologies for questioning the foundation and content of science, while technological advances, specifically atomic and nuclear weaponry, raised anew the question of the role of science in modern culture, politics, and society. In recent years German citizens have had a special interest in the latter. (shrink)
