The proposition that feedback is never necessary in speech recognition is examined for utterances consisting of sequences of words. In running speech the features near word boundaries are often modified according to language-dependent rules. Application of these rules during word recognition requires top-down processing. Because isolated words are not usually modified by rules, their recognition could be achieved by bottom-up processing only.

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.

A corrected and extensively annotated version of the sole meeting between two of the most important figures in twentieth-century intellectual life.

The potential benefits of priming intermittent theta burst stimulation with continuous theta burst stimulation have not been examined in regard to sensorimotor oscillatory activities recorded in electroencephalography. The objective of this study was to investigate the modulatory effect of priming iTBS delivered to the motor cortex on movement-related and mirror visual feedback -induced sensorimotor event-related desynchronization, compared with iTBS alone, on healthy adults. Twenty participants were randomly allocated into Group 1: priming iTBS—cTBS followed by iTBS, and Group 2: non-priming iTBS—sham (...) cTBS followed by iTBS. The stimulation was delivered to the right primary motor cortex daily for 4 consecutive days. EEG was measured before and after 4 sessions of stimulation. Movement-related ERD was evaluated during left-index finger tapping and MVF-induced sensorimotor ERD was evaluated by comparing the difference between right-index finger tapping with and without MVF. After stimulation, both protocols increased movement-related ERD and MVF-induced sensorimotor ERD in high mu and low beta bands, indicated by significant time effects. A significant interaction effect favoring Group 1 in enhancing movement-related ERD was observed in the high mu band [F = 4.47, p = 0.049], compared with Group 2. Our experiment suggests that among healthy adults priming iTBS with cTBS delivered to the motor cortex yields similar effects with iTBS alone on enhancing ERD induced by MVF-based observation, while movement-related ERD was more enhanced in the priming iTBS condition, specifically in the high mu band.

This essay describes conversation as an ensemble accomplishment that can be illuminated by critics working with specific texts within a rhetorical framework. We first establish dialogue as the key concept for any criticism of conversation, specifying the rhetorical dimensions of interpersonal dialogue. Second, we show how template thinking is particularly dangerous for conversational critics and suggest a research (anti)method, based on a coauthorship, that provides a thoroughgoing dialogical access to texts. Finally, we exemplify dialogic criticism of a conversational text by (...) analyzing the famous 1957 dialogue of philosopher Martin Buber and psychologist Carl Rogers. (shrink)

Upon doing something generous for someone with whom you are close, some kind of reciprocity may be appropriate. But it often seems wrong to actually request reciprocity. This chapter explores the wrongness in making these requests, and why they can nevertheless appear appropriate. After considering several explanations for the wrongness at issue (involving, e.g. distinguishing oughts from obligation, the suberogatory, imperfect duties, and gift-giving norms), a novel proposal is advanced. The requests are disrespectful; they express that their agent insufficiently trusts (...) the hearer to recognize their own reasons to reciprocate, and the close relationship between them morally requires this kind of trust. This proposal is articulated and situated in the recent discussion of the normativity of requests. The chapter concludes by explaining how these requests may appear appropriate. Agents in these relationships often have standing to make requests, though the standing is lacking in these particular cases. (shrink)

All organizations have ethics programs which consist of both explicit and implicit parts. This paper defines corporate ethics programs and identifies a number of their components. Corporate ethics programs'' structural and behavioral dimensions are proposed which may allow further examination of such program components and their impacts. Finally, fifteen propositions are suggested which describe the influence of founder values, competitive pressures, leadership, and organizational problems on corporate ethics programs and the manageability of such programs.

Various authors advocate consideration of stakeholder value concerns in organizational decision making. Brenner and Cochran (1990, 1991) propose a stakeholder theory of the firm which contains several propositions and a stakeholder value matrix. In order to begin any stakeholder rnodel validation, an approach is needed to measure stakeholder value and influence weights. We propose a multicriteria decision modeling approach, utilizing the analytic hierarchy process, to estimate stakeholder value matrix weights. This approach is illustrated using a simplified example and suggestions are (...) made regarding the process needed to begin to validate the stakeholder theory of the firm. (shrink)

Many aspects of design require engineers to make choices based on non-quantifiable personal perspectives. These decisions touch issues in aesthetics, ethics, social impact, and responsibility and sustainability. Part of Baylor University’s mission is to provide a learning community in which Christian life values and worldviews might be integrated into academic disciplines. In view of this institutional commitment, members of the Engineering faculty are investigating how Christian worldviews might interact with elements of engineering design in such a way as to produce (...) uniquely Christian insights and inform the non-quantifiable aspects of the engineering process.

Any empirical claim about the role of genes in socioeconomic outcomes involves successfully addressing the identification problem. This commentary argues that socioeconomic outcomes such as education are sufficiently complex, involving so many mechanisms, that understanding the role genes requires the use of formal theoretical structures.

This panel considered the uses of and prospects for the stakeholder theory/approach. After 20 years of popularity, the stakeholder concept has still notemerged as a true theory. However, it offers some unique perspectives on business organizations and there is plenty of room to develop stakeholder theory and research. These session notes are offered to further the scholarly discussion.

This “paper” recalls the events that shaped the first international conference of the International Association for Business and Society. A number of surprises andfortunate circumstances determined the actual nature of our 1992 meeting in Leuven, Belgium. This description provides a brief overview of that conference’s planning and execution.

The process by which auditors consider fraud risk in assessing management’s motivation and character remains under-addressed. This is problematic given the rising tide of narcissism, as well as recent research documenting that both self- and other-perceptions of narcissism influence an array of judgments. While a skeptical attitude is fundamental to the auditor’s gatekeeper role, it remains unclear how auditors form and act on perceptions of client narcissism. With a large sample of experienced accountants as participants, we leverage insights from current (...) narcissism and perceiver effects research to predict (and find) that auditor skepticism responds in a divergent manner to both the auditor’s (1) own antagonistic versus agentic narcissism and (2) perceptions of the client’s antagonistic and agentic narcissism. We discuss the observed opposing behavioral externalities related to these distinct forms of grandiose narcissism, particularly in dynamic interactions between clients and auditors. (shrink)

Most physicians confront the moral and technical challenges of treating persons who are coming to the natural end of their lives. At the level of the health system, this issue becomes a more pressing area for reform as premature death decreases and more people live a full life span. Well-developed countries and international organizations such as the World Health Organization and the Organisation of Economic Cooperation and Development have made recommendations for improving healthcare problems in aging societies. Turkey belongs to (...) the WHO and the OECD. This article describes end-of-life healthcare in Turkey, the design of the healthcare system to meet this need, challenges that should be addressed, and solutions that would be appropriate to Turkish culture and resources.
