Hand function improvement in stroke survivors in the chronic stage usually plateaus by 6 months. Brain-computer interface (BCI)-guided robot-assisted training has been shown to be effective for facilitating upper-limb motor function recovery in chronic stroke. However, the underlying neuroplasticity change is not well understood. This study aimed to investigate the whole-brain neuroplasticity changes after 20-session BCI-guided robot hand training, and whether the changes could be maintained at the 6-month follow-up. Therefore, the clinical improvement and the neurological changes before, immediately after, (...) and 6 months after training were explored in 14 chronic stroke subjects. The upper-limb motor function was assessed by Action Research Arm Test (ARAT) and Fugl-Meyer Assessment for Upper-Limb (FMA), and the neurological changes were assessed using resting-state functional magnetic resonance imaging. Repeated-measure ANOVAs indicated that long-term motor improvement was found by both FMA (F[2,26]= 6.367,p= 0.006) and ARAT (F[2,26]= 7.230,p= 0.003). Seed-based functional connectivity analysis exhibited that significantly modulated FC was observed between ipsilesional motor regions (primary motor cortex and supplementary motor area) and contralesional areas (supplementary motor area, premotor cortex, and superior parietal lobule), and the effects were sustained after 6 months. The fALFF analysis showed that local neuronal activities significantly increased in central, frontal and parietal regions, and the effects were also sustained after 6 months. Consistent results in FC and fALFF analyses demonstrated the increase of neural activities in sensorimotor and fronto-parietal regions, which were highly involved in the BCI-guided training.Clinical Trial Registration:This study has been registered atClinicalTrials.govwith clinical trial registration number NCT02323061.

Following a government campaign run by the Independent Commission Against Corruption (ICAC) in 1994, many Hong Kong companies and trade associations adopted written codes of conduct. The research study reported here examines how and why companies responded, and assesses the impact of code adoption on the moral climate of code adopters. The research involved (a) initial questionnaire surveys to which 184 organisations replied, (b) longitudinal questionnaire-based assessments of moral ethos and conduct in a focal sample of 17 code adopting companies, (...) (c) interviews with 33 managers in the focal companies examining the adoption and impact of the codes, and (d) content analysis of 41 company codes of conduct, including those of most focal companies, plus the ICAC model code.While a mixture of prudential and altruistic reasons were given for code adoption, content analysis suggested that the prime motive was corporate self-defence. The prevailing themes were bribery, conflict of interest, insider information, gambling, moonlighting, accuracy of records and misuse of corporate assets. Wider social responsibility tended to be neglected. Companies appeared to have imposed their codes top-down, emphasising disciplinary procedures rather than ethics training, and appointing neither ethics counsellors nor ombuds-people. The longitudinal study over a seven month period suggested that while moral ethos may have declined, overall standards of perceived conduct had not changed. (shrink)

The friendly expatriate ladies of the chorus in Helen enter having heard loud lamentation issuing from the palace, while engaged, like the Φλα of the chorus in Hippolytus 125ff., in spreading laundered crimson textiles to dry in the sun. The central theme of ‘hearing cries’, with the verb κλυον and nouns of utterance, is reminiscent also of Medea 131ff., where the opening words of the Parodos κλυον Φωνν, κλυον δ βον… allude to Medea's loud utterances сωθεν in 96ff. and 111ff. (...) : here, as there, the Parodos exploits the familiar motif of βοηδρομα. (shrink)

πνοϲ, in general a common word in Greek tragedy, is a cardinal theme in the Heracles. In the first half of the play the glorious saving Labours of the warrior Hero with his bow, club and other weaponry are retrospectively evoked and further enacted. Repeated emphasis on this kind of ‘noble toil’ accords with the heroic definition of ρετ, which traditionally βανει διμχθω–8 the first strophe of the long First Stasimon in honour of Heracles ends with: μνῆϲαι ϲτεφνωμα μ– χθων (...) δι' ελογαϲ θλω γενναων δ' ρετα πνων τοῖϲ θανοϲιν γαλμα. Heracles par excellence merits the title πολπονοϲ and for their individual greatness. πολυ- can mean either ‘much-’, so that it suffices for Amphitryon at 1190ff. to mention a single especially grand and godlike Labour: AM.μϲ μϲ δε γνοϲ πολπονοϲ, π δρυ γιγαντοφνον λθεν ϲν θεο- ϲι Φλεγραον ϲ πεδον ϲπιϲτϲ This we may call the ‘epic’ view of the hero and of the πνοι performed by him cw ϲν θεοϲ. πνοϲ is normally martial in the Iliad.4 Note also, however, that the terminal ϲπιϲτϲ adds an allusion to the kind of martial ρετ most admired by 5th-century Athenians.

So begins one of the most engaging, and variously controversial, musical scenes in Euripides. The Messenger's narrative of the Phantom Helen's disappearance has proved to Menelaus that the Helen standing before him is the real Helen, altogether innocent of elopement to Troy, from whom he has been sundered for seventeen laborious years. The ensuing embrace is developed in a duet which is followed without a break by the so-called ‘Interrogation’, the two together constituting the so-called ‘Recognition Duo’.

A proof is given that there does not exist an event, that is not already in the past for some possible distant observer at the (our) moment that the latter is "now" for us. Such event is as "legally" past for that distant observer as is the moment five minutes ago on the sun for us (irrespective of the circumstance that the light of the sun cannot reach us in a period of five minutes). Only an extreme positivism: "that which (...) cannot yet be observed does not yet exist", can possibly withstand the conclusion concerned. Therefore, there is determinism, also in micro-physics.

This volume, which is part of the Clarendon Aristotle Series, offers a clear and faithful new translation of Books II to IV of Aristotle's Nicomachean Ethics, accompanied by an analytical commentary focusing on philosophical issues. In Books II to IV, Aristotle gives his account of virtue of character in general and of the principal virtues individually, topics of central interest both to his ethical theory and to modern ethical theorists. Consequently major themes of the commentary are connections on the one (...) hand with other relevant Aristotelian texts and on the other with modern writings, both text-related and thematic. Since the main aim of the volume is to make Aristotle's thought as accessible as possible to readers who do not know Greek, considerable care is taken to elucidate both his technical vocabulary and significant features of his Greek idiom. C. C. W. Taylor also provides systematic comparisons with other translations into English and other languages, and frequent references to other commentaries, ancient, medieval, and modern. These features make the work useful to other scholars in the field as well as to students of philosophy, both undergraduate and graduate.In view of the widespread contemporary interest in the topic of virtue, the volume should appeal to students of ethics and to any reader who is concerned to see how fundamental questions of life and conduct were approached in a culture significantly different from our own.

Originally published in 1913, this text was written in anticipation of the King's Speech for that year, which was due to include a Bill for the development of a National System of Education. The text puts forward the view that 'unless the Bill succeeds in making the most of the movement for reform springing from the schools themselves, it can but grant opportunities which will be incompletely utilised'. This book will be of value to anyone with an interest in the (...) history of education and educational reform. (shrink)

Quantum theory predicts that, e.g., in a Stern-Gerlach experiment with electrons the measured spin component $S_Z = \pm \frac{1}{2}$ does not come about by an adjustment at the last moment, a forced “flipping” or “tilting” of the spin (vector), which would imply z-angular momentum exchange between particle and instrument, but will afterward appear to have had the value $\frac{1}{2} or - \frac{1}{2}$ already before the measurement. Because an electron spin cannot have components $ \pm \frac{1}{2}$ in all directions at the (...) same time, the measuring direction has a “privileged” status before the measurement, however we choose that direction, which implies a retroactive effect. A second proof of retroactivity is derived from a special case of the paradox of Einstein, Podolsky, and Rosen. It is strongly suggested by our result that, in essential respects, both Bohr and Einstein were right in their famous controversy about determinism and considering microprocesses “as a whole.”.

De Interpretatione is among Aristotle's most influential and widely read writings; C. W. A. Whitaker presents the first systematic study of this work, and offers a radical new view of its aims, its structure, and its place in Aristotle's system. He shows that De Interpretatione is not a disjointed essay on ill-connected subjects, as traditionally thought, but a highly organized and systematic treatise on logic, argument, and dialectic.

This text and commentary is the first to take account of all the manuscripts and to place the work in its historical and scientific context, as well as the first to describe its manuscript tradition.

Aristotle's treatise De Interpretatione is one of his central works; it continues to be the focus of much attention and debate. C. W. A. Whitaker presents the first systematic study of this work, and offers a radical new view of its aims, its structure, and its place in Aristotle's system, basing this view upon a detailed chapter-by-chapter analysis.By treating the work systematically, rather than concentrating on certain selected passages, Whitaker is able to show that, contrary to traditional opinion, it forms (...) an organized and coherent whole. He argues that the De Interpretatione is intended to provide the underpinning for dialectic, the system of argument by question and answer set out in Aristotle's Topics; and he rejects the traditional view that the De Interpretatione concerns the assertion and is oriented towards the formal logic of the Prior Analytics. In doing so, he sheds valuable new light on some of Aristotle's most famous texts. (shrink)
