Event-related desynchronization, as a proxy for mirror neuron activity, has been used as a neurophysiological marker for motor execution after mirror visual feedback. Using EEG, this study investigated ERD upon the immediate effects of single-session MVF in unimanual arm movements compared with the ERD effects occurring without a mirror, in two groups: stroke patients with left hemiplegia and their healthy counterparts. During EEG recordings, each group performed one session of mirror therapy training in three task conditions: with a mirror, with (...) no mirror, and with a covered mirror. An asymmetry index was calculated from the subtraction of the event-related spectrum perturbations between the C3 and C4 electrodes located over the sensorimotor cortices contralateral and ipsilateral to the moved arm. Results of the effect of task versus group in contralateral and ipsilateral motor areas showed that there was a significant effect of task condition at the contralateral motor area in the high beta band at C3. High beta ERD showed that the suppression was greater over the contralateral hemisphere than it was over the ipsilateral hemisphere in both study groups. The magnitude of low beta ERD in patients with stroke was more suppressed in contralesional C3 under the no mirror compared to that of the covered mirror and similarly more suppressed in ipsilesional C4 ERD under the no mirror compared to that of the mirror condition. The correlation analysis revealed that the magnitude of ERSP power correlated significantly with arm severity in the low and high beta bands in patients with stroke, and a higher asymmetry index in the low beta band was associated with higher arm functioning under the no-mirror condition. There was a shift in sensorimotor ERD toward the contralateral hemisphere as induced by MVF accompanying unimanual movement in both stroke patients and healthy controls. The use of ERD in the low beta band as a neurophysiological marker to indicate the relationships between the amount of MVF-induced ERD attenuation and motor severity, and the outcome indicator for improving stroke patients’ neuroplasticity in clinical trials using MVF are warranted to be explored in the future.

Objective: The objectives of this study are to understand the current functions, structure and operation of hospital ethics committees (HECs) in Shanghai and to facilitate their improvement. Methods: (1) A questionnaire survey, (2) interviews with secretaries and (3) on-site document reviews of HECs in Shanghai were used in the study, which surveyed 33 hospitals. Results: In Shanghai, 57.56% of the surveyed hospitals established HECs from 1998 to 2005. Most HECs used bioethical review of research involving human subjects as well as (...) bioethical review or consultation regarding medical care services and administrative decision- making. Of the surveyed HECs, 14.3% did not provide any formal bioethical training to the HECs’ members and many HECs had no standard operating procedures. Some HECs had no clear definition of what was “conflict of interest” that should be considered by the HECs, while 44.4% of the HECs did not perform continuing review. Discussion: After the issues of related national regulations, more and more hospitals established HECs in Shanghai, but the functions of HECs need to be further developed and formal training on bioethics should be provided to HEC members. To assure the independence and good performance of HECs, the conflict of interest procedure, the standard operating procedures and bioethical review should be improved. Conclusion: HECs in Shanghai had developed in the preceding 10 years and they played great roles in protecting the rights and welfare of human subjects and patients; some areas need improvement.

© 2015, Springer-Verlag Berlin Heidelberg.Genetic studies have identified single nucleotide polymorphisms associated with the risk of prostate cancer. It remains unclear whether such genetic variants are associated with disease aggressiveness. The NCI-SPORE Genetics Working Group retrospectively collected clinicopathologic information and genotype data for 36 SNPs which at the time had been validated to be associated with PC risk from 25,674 cases with PC. Cases were grouped according to race, Gleason score and aggressiveness. Statistical analyses were used to compare the frequency (...) of the SNPs between different disease cohorts. After adjusting for multiple testing, only PC-risk SNP rs2735839 was significantly and inversely associated with aggressive and high-grade disease in European men. Similar associations with aggressive and high-grade disease were documented in African-American subjects. The G allele of rs2735839 was associated with disease aggressiveness even at low PSA levels in both European and African-American men. Our results provide further support that a PC-risk SNP rs2735839 near the KLK3 gene on chromosome 19q13 may be associated with aggressive and high-grade PC. Future prospectively designed, case-case GWAS are needed to identify additional SNPs associated with PC aggressiveness. (shrink)

Sustainable and ethical leadership in the financial industry expand in importance since the financial crisis of 2007–2009. This research examined the level of sustainable and ethical leadership of leaders in mortgage loan originator (MLO) organizations, as perceived by loan originators. The Perceived Leadership Survey (PLIS) developed by Craig and Gustafson (Leadersh Q 9(2):127–145, 1998) and the Sustainable Leadership Questionnaire (SLQ) developed by McCann and Holt (Int J Sustain Strat Manage 2(2):204–210, 2011) were utilized for this research. The survey results yielded (...) high levels of both ethical and sustainable leadership. Employees also felt their leadership was encouraging ethical and sustainable behavior. However, correlations between the PLIS and SLQ did not prove to be dependent or closely correlated. (shrink)

Zeno's paradoxes of motion are considered as challenges to the practice of describing motion in terms of continuous functions. A brief description of some work of adolf gruenbaum toward the resolution of these paradoxes is given. A new form of zeno's dichotomy paradox is described, And it is claimed that the paradox, In this form, Is not amenable to the explanations of gruenbaum. This is demonstrated by giving the new form of the paradox a second, More mathematical description. In a (...) short summary it is claimed that the challenges of zeno's paradoxes are still unanswered. (shrink)

Over the last few years there seems to have been a sharp increase in the number of books that want to spread the news that economics is, or at least can be, fun. This paper sets out to explain in what senses economics is supposed to be fun. In particular, the books in what I will call the economics-made-fun genre will be compared first with papers and books written by economists with the explicit intent of making fun of economics. Subsequently, (...) it will be examined whether or not it makes sense to accuse books in the economics-made-fun genre of economics imperialism, as some commentators have recently done. (shrink)

Mark Blaug and I agree that if there is a realist interpretation of economic behavior to be discerned in Friedman, it is to be found not in Friedman's belief that the profit motive overrides other possible motives, but in his belief that a selection mechanism is working in competitive markets. Our joint sympathy for evolutionary economics is largely based on a conviction that the conception of competition as a dynamic evolutionary process is rather plausible. We disagree, however, on two issues: (...) first, how important the evolutionary conception was for Friedman's overall argument; and, second, whether we can learn something about the real world from rigorous formal analytical models. In this article, I explain and argue for my position on these two issues, and use Nelson and Winter's theory of evolutionary economics to support an illustrate my argument. (shrink)

Many forays have been made by psychoanalysts into the aesthetic realm, particularly in the form of interpretations of works of art and discussions of the particular or general pathology that may predispose individuals toward artistic creativity. Likewise, occasional philosophers have commented on the usefulness of psychoanalysis as a way of approaching areas of mutual interest. This study aims to contribute to this ongoing interdisciplinary dialogue, primarily through a focus on pathography, the term and method originated by Freud in his 1910 (...) monograph on Leonardo da Vinci. ;The thesis begins with an attempt to establish grounds for a dialogue between aesthetics and psychoanalysis by offering a selective review of the literature, identifying three fundamental problems in aesthetics and three basic approaches within psychoanalytic theory, and presenting a discussion of the application of these three modes of psychoanalytic thought to problems of form and content in modern art. ;Next, it is established that pathography, which attempts to probe associations between works of art and the minds that created them, derives from the nineteenth century critical tradition to which Freud was heir. Pathography is subjected to a critique in terms of the ongoing debate in aesthetics concerning problems of intention and expression; finally, its special contributions and limitations are explored. Three models of pathography are presented in detail. Each model with its differing context, motive for interpretation and methodology is scrutinized from an interdisciplinary perspective. ;Beyond pathography, we consider finally the contribution of several post-Freudian theorists who have emphasized the importance of preoedipal development and illuminated certain more general problems of aesthetic interest, i.e., issues centering on response to works of art, creativity and the importance of the external object. The possibility of a developmental line for aesthetic experience is considered, and relevant contemporary infant research is summarized. ;The Appendix offers, beyond pathography, yet another approach of psychoanalysis to art in which the work of art is considered sui generis, not, as in pathography, tied inextricably to the mind of its creator. A statement concerning the vicissitudes of interdisciplinary scholarship concludes the study. (shrink)

How can we be certain that software is reliable? Is there any method that can verify the correctness of software for all cases of interest? Computer scientists and software engineers have informally assumed that there is no fully general solution to the verification problem. In this paper, we survey approaches to the problem of software verification and offer a new proof for why there can be no general solution.

In the present research, we qualitatively document the process by which spiritual leader and leadership emerge in religion-based organizations. Data from 26 participants in three religion-based organizations revealed three cardinal themes that depict the development of spiritual leader and spiritual leadership, the process of developing a spiritual leader and spiritual leadership, and outcomes of spiritual leader and leadership development. Based on the results, we propose a model that depicts the phases involved in the development of spiritual leader/leadership in the religion-based (...) workplace. These phases are proposed to impact the outcomes for the leader, followers, and the organization. The implications of our results are discussed. (shrink)

But these assumptions or philosophical conclusions should not be called research in music education because they do not provide any behavioral evidence as support.

The use of logico-semiotic and systems-structural approaches in the analysis of types of abstraction and forms of generalization of concepts was begun in the '50s and '60s by D. P. Gorskii, who at that time introduced the concept of idealization into the terminology. In the early '70s he continued his analysis of the problem of scientific understanding, delineating the specific features of definitions in the theories of natural sciences and in the social science disciplines. In the book under review, Gorskii (...) in a certain sense sums up his results and develops them further. (shrink)
