Originally published in 1936, this book presents the ancient Greek text of the paraphrases and quotations of Zeno's philosophical arguments, together with a facing-page English translation and editorial commentary. Detailed notes are incorporated throughout and a bibliography is also included. This book will be of value to anyone with an interest in Zeno and ancient philosophy.

The object of this paper is to show the predominance of the influence of geometrical ideas in Aristotle's account of first principles in the Posterior Analytics— to show that his analysis of first principles is in its essentials an analysis of the first principles of geometry as he conceived them. My proof of this falls into two parts. I. A consideration of the parallel between Aristotle's and Euclid's account of first principles. II. A comparison between the general movement of thought (...) in the Aristotelian παγωγ and πδειξις and in the δινοια and νησις of the Platonic dialectic. (shrink)

I start with two contradictory statements: Jaeger, Aristotle, p. 330: ‘Thus all indications point to a late date for the origin of the philosopher's zoological works.’ D'Arcy Thompson, Historia Animalium, Prefatory Note: ‘It can be shown that Aristotle's natural history studies were carried on, or mainly carried on, in his middle age, between his two periods of residence at Athens.‘.

The two passages in question are I. the discussion of Justice in Bk. V. chs. I-II, and in particular the definition and subdivisions of Corrective Justice ; and II. the discussion of the voluntaryand προαρεσς in Bk. III chs. II-II. My object is to show that each is better understood if it is seen in the light of contemporary legal ideas and practice.

The following remarks on the aviary simile have been prompted by Professor Hackforth's article in C.Q. January 1938, pp. 27 ff., in which he in turn comments on certain points in Professor Cornford's treatment in his Plato's Theory of Knowledge. Commenting on 199c–d C. suggests that P.'s criticism in that passage might be met by the inclusion in the aviary of ‘complex objects such as the “sum of 7 and 5”.… It is this object that I identify with 11 when (...) I make my false judgement.… False judgement can be explained as the wrong putting together of two pieces of knowledge’—i.e. 11 and ‘the sum of 7 and 5’. C. further suggests that P. has overlooked this possibility because he persists in speaking as if we judged not ‘that the sum of 7 and 5 is 11’ but that ‘12 is 11 ’. H. replies that this criticism of C.'s is not valid because P. understands the knowledge of 11 and 12 to include a knowledge of the various sums that make up these numbers. There could, therefore, be no ‘question of “putting together” such a piece of knowledge as 7 + 5 = 12 with a different piece of knowledge, viz. the knowledge of 12. They are not different pieces; they are the same piece.’. (shrink)

The following brief memoir of Wittgenstein needs a few preliminary words of explanation. Among those who attended his lectures and discussions in the years it covers was D. G. James, who later became Professor of English at Bristol University and then Vice-Chancellor of Southampton University. I met him both in Bristol and Southampton, and on one occasion suggested to him that some of us who had known Wittgenstein, but who had not become professional philosophers, might write down our recollections of (...) him, and that he and I should start. What prompted the suggestion was, I think, the publication of Norman Malcolm's book, and a feeling that the non-professionals might have something to contribute to the assessment of Wittgenstein, particularly as a person. I wrote a preliminary draft and sent it to James; but he never responded, there was much else to do, I let the matter rest, and now James is dead. I wrote in about the year 1960 on holiday and away from any books of reference and from my own notes of Wittgenstein's lectures and conversations. I have shown the typescript to a few interested people, but because of its preliminary and unfinished nature have not previously thought of publication. It has recently been suggested to me that it might be of more general interest, and I publish it now as it was written, with one or two trifling alterations. I am well aware of its limitations. It was intended to give an impression of Wittgenstein as a person rather than as a philosopher, and the rather miscellaneous collection of remarks in section 3 have that in view rather than any more strictly ‘philosophical’ intention. Others may well question some of the detail and disagree with some of the opinions expressed. And there are some things which I might put rather differently today. But if the memoir has any interest it is best left as it was written. (shrink)

Medium- and high-spin states of Pr-134 were populated using the Cd-116(Na-23, 5n) reaction and studied with the GAMMASPHERE spectrometer. Several new bands have been found in this nucleus, one of them being linked to the previously observed chiral-candidate twin-band structure. The ground state of Pr-134 could be determined through establishing a level structure that connects the two previously known long-lived isomeric states. Unambiguous spin-parity assignments for the excited states could be performed based on the known 2(-) spin-parity of the ground (...) state combined with the present experimental data. Intrinsic single-particle configurations have been assigned to the newly observed bands on the basis of the measured B(M1)/B(E2) ratios, alignments, band-crossing frequencies, bandhead spins, the observed single-particle configurations in the neighboring nuclei, and taking into account the predictions of total Routhian surface and tilted-axis cranking calculations.

BackgroundIn the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort, participants underwent magnetic resonance imaging (MRI) of the brain, heart, and abdomen, that generated incidental findings (IFs). The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies.MethodsBetween 2013 and 2019, 8252 participants (...) (mean age 58 ± 9 years, 54% women) were recruited with a follow-up questionnaire administered to 909 participants (40% response rate) at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported.ResultsSevere structural abnormalities occurred in 8.3% (95% confidence interval 7.7–8.9%) of participants, with the highest proportions found in the brain (4.2%) and abdomen (3.1%). The majority of participants (97%) informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants (90%) would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy.ConclusionThe management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/nct02220582. (shrink)

This book provides practical and research-based chapters that offer greater clarity about the particular kinds of teacher reflection that matter and avoids talking about teacher reflection generically, which implies that all kinds of reflection are of equal value.

High-spin states have been studied in Pr-135(59), populated through the Cd-116(Na-23,4n) reaction at 115 MeV, using the Gammasphere gamma-ray spectrometer. The negative-parity yrast band has been significantly extended to spin similar to 45 (h) over bar and excitation energy 21.5 MeV, showing evidence for several rotational alignments. The positive-parity yrast band of Ce-135(58), populated through the p4n channel of this reaction, was also populated to spin similar to 38 (h) over bar and excitation energy 18 MeV. Cranking calculations indicate that (...) these nuclei are soft with respect to the triaxiality parameter gamma and that several competing nuclear shapes occur at high spin. (shrink)

A cross-sectional study to ascertain what the Singapore population would regard as material risk in the anaesthesia consent-taking process and identify demographic factors that predict patient preferences in medical decision-making to tailor a more patient-centered informed consent. A survey was performed involving patients 21 years old and above who attended the pre-operative evaluation clinic over a 1-month period in Singapore General Hospital. Questionnaires were administered to assess patients’ perception of material risks, by trained interviewers. Patients’ demographics were obtained. Mann–Whitney U (...) test and Kruskal-Wallis one-way analysis of variance was used. Statistical significance was taken at p < 0.05. Four hundred fourteen patients were eligible of which 26 refused to participate and 24 were excluded due to language barrier. 364 patients were recruited. A higher level of education, being employed and younger age group are factors identified in patients who wanted greater participation in medical decisions. Gender, marital status, type of surgery, and previous surgical history did not affect their level of participation. The complications most patients knew about were Nausea, Drowsiness and Surgical Wound Pain. Patients ranked Heart Attack, Death and Stroke as the most significant risks that they wanted to be informed about in greater detail. Most patients wanted to make a joint decision with the anaesthetist, instead of letting the doctor decide or deciding for themselves. Discussion with the anaesthetist is the preferred medium of communication compared to reading a pamphlet or watching a video. Age and educational level can influence medical decision-making. Despite the digital age, most patients still prefer a clinic consult instead of audio-visual multimedia for pre-operative anaesthetic counselling. The local population appears to place greater importance on rare but serious complications compared to common complications. This illustrates the need to contextualize information provided during informed consent to strengthen the doctor-patient relationship. (shrink)

A laboratory-testable, solid-state Maxwell demon is proposed that utilizes the electric field energy of an open-gap p-n junction. Numerical results from a commercial semiconductor device simulator (Silvaco International–Atlas) verify primary results from a 1-D analytic model. Present day fabrication techniques appear adequate for laboratory tests of principle.

Little is known about distance processing in patients with posterior brain damage. Although many investigators have claimed that distance estimates are normal or abnormal in some of these patients, many of these observations were made informally and the examiners often asked for relative, and not absolute, distance estimates. The present investigation served two purposes. First, we wanted to contrast the use of distance information in peripersonal space for perceptual report as opposed to visuomotor control in our visual form agnosic patient, (...) DF. Second, we wanted to see to what extent her abilities to process distance cues were dependent on binocular vision, in light of Milner et al.'s (1991) observations of preserved stereopsis in DF, and Dijkerman et al.'s (1996) and Marotta et al.'s (1997) observations that her visual guidance of grasping may be particularly dependent on binocular vision of the target. We hypothesized that DF's visuomotor responses would show normal sensitivity to target distance, while her perceptual estimates would not. In the first experiment, we required DF and two age- and sex-matched control subjects to reach out and grasp black cubes placed at varying distances, or to estimate the distance of the cubes from the hand starting position without making a reaching movement. In the second experiment, we required DF and two age-matched control subjects to point as rapidly and accurately as possible to small LED targets which differed in spatial location, under binocular and monocular conditions. The results showed that, relative to the control subjects, DF's grasping movements produced normal peak velocity-distance scaling-when she reached for blocks which varied in depth or pointed to LED targets which were presented at different distances in depth. In contrast, in the cube experiment, her verbal estimates of object distance were poorly scaled, although they improved slightly under the binocular conditions. The results are discussed in terms of current theories of processing streams in extrastriate visual cortex and the distinction between categorical and coordinate spatial processing. (shrink)
