Multiple cortical areas of the human brain motor system interact coherently in the low frequency range (< 0.1 Hz), even in the absence of explicit tasks. Following stroke, cortical interactions are functionally disturbed. How these interactions are affected and how the functional organization is regained from rehabilitative treatments as people begin to recover motor behaviors has not been systematically studied. We recorded the intrinsic functional magnetic resonance imaging (fMRI) signals from 30 participants: 17 young healthy controls and 13 aged stroke (...) survivors. Stroke participants underwent mental practice (MP) or both mental practice and physical therapy (MP + PT) within 14-51 days following stroke. We investigated the network activity of five core areas in the motor-execution network, consisting of the left primary motor area (LM1), the right primary motor area (RM1), the left pre-motor cortex (LPMC), the right pre-motor cortex (RPMC) and the supplementary motor area (SMA). We discovered that (i) the network activity dominated in the frequency range 0.06 Hz – 0.08 Hz for all the regions, and for both able-bodied and stroke participants (ii) the causal information flow between the regions: LM1 and SMA, RPMC and SMA, RPMC and LM1, SMA and RM1, SMA and LPMC, was reduced significantly for stroke survivors (iii) the flow did not increase significantly after MP alone and (iv) the flow among the regions during MP+PT increased significantly. We also found that sensation and motor scores were significantly higher and correlated with directed functional connectivity measures when the stroke-survivors underwent MP+PT but not MP alone. The findings provide evidence that a combination of mental practice and physical therapy can be an effective means of treatment for stroke survivors to recover or regain the strength of motor behaviors, and that the spectra of causal information flow can be used as a reliable biomarker for evaluating rehabilitation in stroke survivors.

A long-standing question in cognitive science is how high-level knowledge is integrated with sensory input. For example, listeners can leverage lexical knowledge to interpret an ambiguous speech sound, but do such effects reflect direct top-down influences on perception or merely postperceptual biases? A critical test case in the domain of spoken word recognition is lexically mediated compensation for coarticulation (LCfC). Previous LCfC studies have shown that a lexically restored context phoneme (e.g., /s/ in Christma#) can alter the perceived place of (...) articulation of a subsequent target phoneme (e.g., the initial phoneme of a stimulus from a tapes-capes continuum), consistent with the influence of an unambiguous context phoneme in the same position. Because this phoneme-to-phoneme compensation for coarticulation is considered sublexical, scientists agree that evidence for LCfC would constitute strong support for top–down interaction. However, results from previous LCfC studies have been inconsistent, and positive effects have often been small. Here, we conducted extensive piloting of stimuli prior to testing for LCfC. Specifically, we ensured that context items elicited robust phoneme restoration (e.g., that the final phoneme of Christma# was reliably identified as /s/) and that unambiguous context-final segments (e.g., a clear /s/ at the end of Christmas) drove reliable compensation for coarticulation for a subsequent target phoneme. We observed robust LCfC in a well-powered, preregistered experiment with these pretested items (N = 40) as well as in a direct replication study (N = 40). These results provide strong evidence in favor of computational models of spoken word recognition that include top–down feedback. (shrink)

The study aims to ascertain how different levels of society have been influenced by the impact of pandemics over the last many years. The study also determines the societal implications of the COVID-19 pandemic. The integrative literature survey method is adopted to extract the secondary data pertinent to the socio-economic effect of pandemics and COVID-19 on society. Primary data is collected to diagnose the impact of the COVID-19 pandemic and lockdown on employees (N = 210) working in the Indian organized (...) sector. Findings of the study suggest that pandemics have been a cause of economic slowdown measured with a fall in gross domestic product (GDP) at the macro level. The reduced level of economic activity is found to be negatively related to an individual socio-economic status building their psychological distress. The descriptive analysis of the data reveals that although employees have managed their jobs and finances during COVID-19, they have experienced stress in their lives due to the pandemic. The study assimilates the pandemic effect using inductive reasoning to develop a COVID quadrilateral conceptual framework. (shrink)

Purpose The high rate of internet penetration has led to the proliferation of social media use, even at the workplace, including academia. This research attempts to develop a topology and thereby determine the dominant use motive for faculty’s use of SM. Design/methodology/approach In this two-part study, a two-stage research design has been adopted for topology development based on the application of Uses and Gratifications Theory. In the second part, the Technology Acceptance Model is applied to discern the dominant motive for (...) SM use in academia. Findings The work is able to develop a seven-item topology, conforming to the basic three use motives, namely, hedonic, utilitarian and social. The work shows faculty attach more value to the instrumental utility of SM, while the hedonic function is also significant. Practical implications Discerning dominant motive implies that SM use at the workplace should not be banned, rather effective regulated use will instil the faculty to enhance work outcomes. The conceptualisation of topology for SM use in academia at the workplace can aid in designing an effective organisation policy, and design of an internal SM platform. Originality/value The study is unique towards topology development for academic faculty and has many important implications for management and academia, especially towards policy design for SM use at the workplace.

This volume explores the reorganisation of knowledge taking place in the course of Galileo's research process extending over a period of more than thirty years, pursued within a network of exchanges with his contemporaries, and documented by a vast collection of research notes. It has revealed the challenging objects that motivated and shaped Galileo's thinking and closely followed the knowledge reorganization engendered by theses challenges. It has thus turned out, for example, that the problem of reducing the properties of pendulum (...) motion to the laws governing naturally accelerated motion on inclined planes was the mainspring for the formation of Galileo's comprehensive theory of naturally accelerated motion.

We recently reported strong, replicable (i.e., replicated) evidence for lexically mediated compensation for coarticulation (LCfC; Luthra et al., 2021), whereby lexical knowledge influences a prelexical process. Critically, evidence for LCfC provides robust support for interactive models of cognition that include top‐down feedback and is inconsistent with autonomous models that allow only feedforward processing. McQueen, Jesse, and Mitterer (2023) offer five counter‐arguments against our interpretation; we respond to each of those arguments here and conclude that top‐down feedback provides the most parsimonious (...) explanation of extant data.

Visual word recognition is facilitated by the presence of orthographic neighbors that mismatch the target word by a single letter substitution. However, researchers typically do not consider where neighbors mismatch the target. In light of evidence that some letter positions are more informative than others, we investigate whether the influence of orthographic neighbors differs across letter positions. To do so, we quantify the number of enemies at each letter position (how many neighbors mismatch the target word at that position). Analyses (...) of reaction time data from a visual word naming task indicate that the influence of enemies differs across letter positions, with the negative impacts of enemies being most pronounced at letter positions where readers have low prior uncertainty about which letters they will encounter (i.e., positions with low entropy). To understand the computational mechanisms that give rise to such positional entropy effects, we introduce a new computational model, VOISeR (Visual Orthographic Input Serial Reader), which receives orthographic inputs in parallel and produces an over‐time sequence of phonemes as output. VOISeR produces a similar pattern of results as in the human data, suggesting that positional entropy effects may emerge even when letters are not sampled serially. Finally, we demonstrate that these effects also emerge in human subjects' data from a lexical decision task, illustrating the generalizability of positional entropy effects across visual word recognition paradigms. Taken together, such work suggests that research into orthographic neighbor effects in visual word recognition should also consider differences between letter positions. (shrink)

By this study, the academicians and researchers will focus greater attention on the rapidly developing human-techno-centric world to fulfill the organizations’ service promises. The study contributes to the marketing ethics literature, particularly to the literature related to ethical issues in product marketing. (shrink)

This study pragmatically makes a descriptive analysis of metadiscourse in academic lectures from the perspective of the relevance-adaptation theory. Based on the relevance theory and the adaptation theory, the relevance-adaptation model is constructed to explore the occurrence, the pragmatic description and the role of metadiscourse in academic lectures. The data is collected from George Lakoff’s 10 academic lectures on cognitive linguistics at Beijing University of Aeronautics and Astronautics in 2004 and some academic lectures audio-taped in classrooms. The results of the (...) study show that 1) the occurrence of metadiscourse in academic lectures is pervasive; 2) the process of choosing appropriate metadiscourse is dynamic and the result of searching for relevance and making contextual adaptations – the process of searching for relevance of metadiscourse is measured in terms of three pairs of the distinctions, namely, contextual effect and processing effort, explicature and implicature, and conceptual meaning and procedural meaning, and contextual adaptations of metadiscourse are constrained by such factors as linguistic reality, psychological motivations and social conventions; 3) the role of metadiscourse in academic lectures is an active discourse constructor.

Direct electrical stimulation has been widely applied in both guidance of lesion resection and scientific research; however, the design and selection of intraoperative cognitive mapping tasks have not been updated in a very long time. We introduce updated mapping tasks for language and non-language functions and provide recommendations for optimal design and selection of intraoperative mapping tasks. In addition, with DES becoming more critical in current neuroscientific research, a task design that has not been widely used in DES yet was (...) introduced for more delicate mapping of brain functions especially for research purposes. We also illustrate the importance of designing a common task series for DES and other non-invasive mapping techniques. This review gives practical updated guidelines for advanced application of DES in clinical and neuroscientific research. (shrink)

Anknüpfend an den Beitrag von U. Steinvorth in Heft 1/1980 wird die Auffassung vertreten, daß die moderne allgemeine Wissenschaftstheorie bisher keine überzeugende Antwort auf die Frage nach dem Status der Politischen Wissenschaft und ihrer theoretischen Erzeugnisse gegeben hat. In diesem Beitrag wird in Auseinandersetzung mit Steinvorth u. a. hervorgehoben: Analog zu der These, daß in der Politik Vernünftigkeit nicht auf Rationalität reduziert werden darf, ist es weder möglich noch wünschenswert, für alle spezifischen politischen Wertungen einen Erklärungstyp zu begründen oder als (...) verbindlich vorzuschreiben. Die Wissenschaftstheorie muß sich in bezug auf die Frage nach dem Status "politischer" Theorien mit einem Theorietypus beschäftigen, der ein neues Abgrenzungskriterium voraussetzt, nämlich einen spezifischen Satz von Prinzipien und Regeln zur Konstruktion politikwissenschaftlicher Theorien.

“The characteristics of China in the world,” as a constant refrain of the contemporary Chinese people, has been discussed in academic circles for nearly a hundred years. It has become more and more popular in recent years, with both government and ambitious scholars continuously appealing for attention to its necessity, significance, and urgency. Obviously, to talk to the world or to be accepted by the world, we must first know who we are and what the world is like. This century-long (...) history of “Chinese education in the world” makes it necessary to consider the historical background when thinking about the characteristics of Chinese education. We attempt to integrate this history into what follows.The ideas... (shrink)

Das weit uber die Zeit seiner Abfassung und uber die Grenzen seines Entstehungslandes hinaus unter dem Namen "Qabusname" bekannte, literarisch wie kulturgeschichtlich bedeutsame Werk heisst wortlich "Buch der Ratschlage," persisch "nasihat-name." Sein Verfasser Kej Kawus wurde um 1021/22 n.Chr. geboren und genoss die fur die persischen Furstensohne seit Jahrhunderten vorgeschriebene Erziehung, bei der eine Synthese von ritterlichen und geistigen, vornehmlich religiosen Tugenden angestrebt wurde. Es handelt sich um eines der interessantesten und eigenartigsten Erzeugnisse der mittelalterlichen iranischen Literatur. Mit Recht werden (...) der intime Ton des Werks und die reizvolle Schlichtheit der hubschen Anekdoten sowie die auf Schmuck verzichtende Einfachheit der Erzahlkunst geruhmt. Die vorliegende Ubersetzung des "Qabusname" ist die erste in deutscher Sprache, die nach dem persischen Original vorgenommen wurde. Die einzige fruhere deutsche Ubersetzung des Orientalisten H. F. von Diez erfolgte aus dem Turkischen und wurde 1811 veroffentlicht. Schon Goethe beschaftigte sich bei seiner Begegnung mit dem klassischen Schrifttum der Perser unter der Fuhrung H. F. von Diez eindringlich mit dem Qabusname. Der Beziehung des Dichters zu diesem so bedeutsamen Stuck der persischen Literatur ist daher ein besonderes Kapitel gewidmet. (shrink)

Die Bildwissenschaft, so scheint es, steckt in einer Sackgasse: Teile von ihr sind zur antiaufklärerischen Ideologie geworden, die Interpreten erlaubt, autoritäre Positionen der Auslegung als Macht des Bildes zu beschreiben. Zeit, sie vom Kopf auf die Füsse zu stellen. Um dies einzulösen, rekonstruiert Martin Büchsel akribisch die wichtigsten bildwissenschaftlichen Theorien der letzten Jahrzehnte inklusive ihrer impliziten Ideologien und Mythen und kontrastiert diese mit aufklärerischen Positionen. Dabei bezieht die sorgsam ausgearbeitete Monographie alle international relevanten Theoretiker und Theorien in seine Überlegungen mit (...) ein. Geleistet wird eine fundamentale Kritik der Bildwissenschaften, gleichermassen kann das Buch aber auch als vertiefende Einführung in dieselben dienen. Womit das Potenzial dieser Studie noch keineswegs ausgeschöpft ist: In einem zweiten Teil entwirft Büchsel Eckpfeiler einer zukünftigen, vorstellungskritischen Bildwissenschaft, die Philosophie, Philologie und Kunstgeschichte höchst produktiv miteinander ins Gespräch bringt.
