BackgroundReconciling results obtained using different types of sensory measures is a challenge for autism sensory research. The present study used questionnaire, psychophysical, and neurophysiological measures to characterize autistic sensory processing in different measurement modalities.MethodsParticipants were 46 autistic and 21 typically developing 11- to 14-year-olds. Participants and their caregivers completed questionnaires regarding sensory experiences and behaviors. Auditory and somatosensory event-related potentials were recorded as part of a multisensory ERP task. Auditory detection, tactile static detection, and tactile spatial resolution psychophysical thresholds were (...) measured.ResultsSensory questionnaires strongly differentiated between autistic and typically developing individuals, while little evidence of group differences was observed in psychophysical thresholds. Crucially, the different types of measures appeared to be largely independent of one another. However, we unexpectedly found autistic participants with larger auditory Tb ERP amplitudes had reduced hearing acuity, even though all participants had hearing acuity in the non-clinical range.LimitationsThe autistic and typically developing groups were not matched on cognitive ability, although this limitation does not affect our main analyses regarding convergence of measures within autism.ConclusionOverall, based on these results, measures in different sensory modalities appear to capture distinct aspects of sensory processing in autism, with relatively limited convergence between questionnaires and laboratory-based tasks. Generally, this might reflect the reality that laboratory tasks are often carried out in controlled environments without background stimuli to compete for attention, a context which may not closely resemble the busier and more complex environments in which autistic people’s atypical sensory experiences commonly occur. Sensory questionnaires and more naturalistic laboratory tasks may be better suited to explore autistic people’s real-world sensory challenges. Further research is needed to replicate and investigate the drivers of the unexpected association we observed between auditory Tb ERP amplitudes and hearing acuity, which could represent an important confound for ERP researchers to consider in their studies.

When humans are required to perform two or more tasks concurrently, their performance declines as the tasks get closer together in time. Here, we investigated the mechanisms of this cognitive performance decline using a dual-task paradigm in a simulated driving environment, and using drift-diffusion modeling, examined if the two tasks are processed in a serial or a parallel manner. Participants performed a lane change task, along with an image discrimination task. We systematically varied the time difference between the onset of (...) the two tasks and measured its effect on the amount of dual-task interference. Results showed that the reaction times of the two tasks in the dual-task condition were higher than those in the single-task condition. SOA influenced the RTs of both tasks when they were presented second and the RTs of the image discrimination task when it was presented first. Results of drift-diffusion modeling indicated that dual-task performance affects both the rate of evidence accumulation and the delays outside the evidence accumulation period. These results suggest that a hybrid model containing features of both parallel and serial processing best accounts for the results. Next, manipulating the predictability of the order of the two tasks, we showed that in unpredictable conditions, the order of the response to the two tasks changes, causing attenuation in the effect of SOA. Together, our findings suggest higher-level executive functions are involved in managing the resources and controlling the processing of the tasks during dual-task performance in naturalistic settings.

The term fuzzy logic is used in this paper to describe an imprecise logical system, FL, in which the truth-values are fuzzy subsets of the unit interval with linguistic labels such as true, false, not true, very true, quite true, not very true and not very false, etc. The truth-value set, , of FL is assumed to be generated by a context-free grammar, with a semantic rule providing a means of computing the meaning of each linguistic truth-value in as a (...) fuzzy subset of [0, 1].Since is not closed under the operations of negation, conjunction, disjunction and implication, the result of an operation on truth-values in requires, in general, a linguistic approximation by a truth-value in . As a consequence, the truth tables and the rules of inference in fuzzy logic are (i) inexact and (ii) dependent on the meaning associated with the primary truth-value true as well as the modifiers very, quite, more or less, etc. (shrink)

This paper focuses on the influence of cultural familiarity on getting the most out of an e-negotiation for merger or acquisition based on subjective and objective negotiation behaviors. We examined if cultural awareness could increase the rate of negotiation self-efficacy, shorten the length of negotiation and optimize deal closure results. To do so, firstly we investigate the concept of e-negotiation and its development in the last two decades. Then a series of systematic reviews is performed on the parameters influencing the (...) success in offline and online merger or acquisition negotiations. We also considered the main traits of Western and Middle Eastern Arab cultures on negotiations. The results show that many of the requirements of successful collaboration, or negotiations, with Arab managers can currently happen only through face-to-face meetings. (shrink)

It has been argued that metaphor and emotion processing are tightly linked together. Here we explore whether neuroscientific evidence supports this claim.

We analyze von Weizsäcker’s view regarding the concept of information in physics. In his view, information arises from the reduction of properties of a physical object to their logical descriptive propositions. The smallest element of a lattice of propositions is an atom of information which is considered as the essence of every physical identity including position space. von Weizsäcker calls this element, “ur”. Moreover, Biological evolution is described in terms of enhancement of the variety of forms. Form could be also (...) reduced to descriptive logical propositions, thus to atoms of information. Therefore, information is the fundamental basis in von Weizsäcker’s plan for unifying all branches of Physics including Chemistry and Biology. Yet, there are inadequacies in his lines of reasoning, critically assessed in this paper. (shrink)

The use of transcranial Electrical Stimulation in the modulation of cognitive brain functions to improve neuropsychiatric conditions has extensively increased over the decades. tES techniques have also raised new challenges associated with study design, stimulation protocol, functional specificity, and dose-response relationship. In this paper, we addressed challenges through the emerging methodology to investigate the dose-response relationship of High Definition-transcranial Direct Current Stimulation, identifying the role of negative valence in tinnitus perception. In light of the neurofunctional testable framework and tES application, (...) hypotheses were formulated to measure clinical and surrogate endpoints. We posited that conscious pairing adequately pleasant stimuli with tinnitus perception results in correction of the loudness misperception and would be reinforced by concurrent active HD-tDCS on the left Dorsolateral Prefrontal Cortex. The dose-response relationship between HD-tDCS specificity and the loudness perception is also modeled. We conducted a double-blind, randomized crossover pilot study with six recruited tinnitus patients. Accrued data was utilized to design a well-controlled adaptive seamless Bayesian dose-response study. The sample size and optimum interims were anticipated for adaptive decision-making about efficacy, safety, and single session dose parameters. Furthermore, preliminary pilot study results were sufficient to show a significant difference within the longitudinally detected self-report tinnitus loudness between before and under positive emotion induction. This study demonstrated a research methodology used to improve emotion regulation in tinnitus patients. In the projected method, positive emotion induction is essential for promoting functional targeting under HD-tDCS anatomical specificity to indicate the efficacy and facilitate the dose-finding process. The continuous updating of prior knowledge about efficacy and dose during the exploratory stage adapts the anticipated dose-response model. Consequently, the effective dose range to make superiority neuromodulation in correcting loudness misperception of tinnitus will be redefined. Highly effective dose adapts the study to a standard randomized trial and transforms it into the confirmatory stage in which active HD-tDCS protocol is compared with a sham trial. Establishing the HD-tDCS intervention protocols relying on this novel method provides reliable evidence for regulatory agencies to approve or reject the efficacy and safety. Furthermore, this paper supports a technical report for designing multimodality data-driven complementary investigations in emotion regulation, including EEG-driven neuro markers, Stroop-driven attention biases, and neuroimaging-driven brain network dynamics.

This study examined the performances of three groups of participants in interpreting metaphors in three different conditions: congruent gesture-prime conditions, opposite gesture-prime conditions, and no-prime conditions. In congruent gesture-prime conditions, each metaphor was preceded by the congruent gestural representation of metaphor schema. In opposite gesture-prime conditions, each metaphor was preceded by the opposite gestural representation of metaphor schema. The results showed that participants of congruent gesture-prime conditions had the best performance in interpreting metaphors, while participants of opposite gesture-prime conditions had (...) the worst performance. It is suggested that metaphor schema is an important part of metaphorical meaning of a metaphor. Therefore, when this part of meaning is activated by a gestural prime, metaphor comprehension is facilitated. Furthermore, when a schema is used to metaphorically describe a concept or an event, that schema and the neural network that represents it become one part of a larger interconnected neural network that represents the meaning of the metaphor. It could mean that the activation of one part of it could facilitate the activation of the whole of the network. Finally, it is emphasized that a gesture that depicts the schema of a metaphor is in fact the embodied realization of that metaphor. (shrink)

Representational transformation is a technique for deepening our understanding of mathematical concepts and facilitating the process of solving mathematical problems. This article suggests that representational transformation can contribute to thought processes in four ways. Firstly, representational transformation helps people employ a wider range of cognitive resources. When one representation of a concept or a problem is transformed into another representation, the sensory-motor resources that are involved in the processing of the base representation are employed to process the target representation. Secondly, (...) representational transformation helps in the process of organizing scattered information into suitable units. This gives structure to various parts of information and makes them much easier to handle. Thirdly, representational transformation helps in the process of suppressing irrelevant information and unnecessary elements of problems. This is a key step in organizing and structuring information. Fourthly, representational transformation helps in the process of discovering general rules and turning them into explicit knowledge. (shrink)

This study measured hand and head action strengths of eight typical emotional states using an authentic but implicit emotion elicitation task. Participants listened to and then retold five stories in which eight typical emotional states were experienced by the narrators. The number of hand and head gestures that occur naturally while experiencing an emotional state was used as an index to determine the hand and head action strength of that emotional state. Results showed a larger number of head gestures than (...) hand gestures, suggesting that head action strengths of the eight emotional states are stronger than their hand action strengths. These findings are consistent with the data extracted from Lancaster Sensorimotor Norms (LSN), although the two sets of data were gathered in two completely different experimental conditions and in two different languages. Furthermore, our data showed a prototypical directionality effect for the typical emotional states, specifically, happiness, anger and pride were primarily accompanied by upward gestures but downward gestures for sadness and shame; surprise was primarily accompanied by forward gestures but backward gestures for fear and disgust.

With regard to the issue of the differences of the sexes, our study focuses on traditional games in Kabylie, taken and defined as part of the field of motor praxiology. A discipline inspired by the work of Pierre Parlebas. We will attempt through a field survey, to identify and interpret the meaning and distribution of the traditional games played by the women of Kabylie. From this perspective, the analysis of the internal logics of the practices are related to the system (...) of interactions between players and their environment. This reveals valuable information on the structures underlying traditional games, and their ethno-motor characteristics as well as the world of ethnology of this vast mountainous region of Kabylie. By analyzing 92 traditional games played in the region of Kabylie allowed us to highlight on the one hand the cultural specificity, and on the other the richness of the socio-cultural aspects of this region. By examining how a game constitutes a cultural identity element of a geographical space, we explain the meaning of sport culture and identity of the Kabylie, by focusing particularly on the place of women and the indicators that reveal the relationships between men and women and distinguish the distribution of female and male roles. This also allows an understanding of the nature of traditional sports and their differentiation in terms of socialization between boys and girls. (shrink)

This volume looks at how accumulation in postcolonial capitalism blurs the boundaries of space, institutions, forms, financial regimes, labour processes, and economic segments on one hand, and creates zones and corridors on the other. It draws our attention to the peculiar but structurally necessary coexistence of both primitive and virtual modes of accumulation in the postcolony. From these two major inquiries it develops a new understanding of postcolonial capitalism. The case studies from India and Sri Lanka discuss the production of (...) urban spaces of capital extraction, institutionalization of postcolonial finance capital, gendering of work forms, establishment of new forms of labour, formation of and changes in caste and racial identities and networks, and securitization-and thereby confirm that no study of contemporary capitalism is complete without thoroughly addressing the postcolonial condition. By challenging the established dualities between citizenship-based civil society and welfare-based political society, exploring critically the question of colonial and postcolonial difference, and foregrounding the material processes of accumulation against the culturalism of postcolonial studies, this volume redefines postcolonial studies in South Asia and beyond. It is invaluable reading for students and scholars of South Asian studies, sociology, cultural and critical anthropology, critical and praxis studies, and political science. (shrink)

. Night driving is one of the major factors which affects traffic safety. Although detecting oncoming vehicles at night time is a challenging task, it may improve traffic safety. If the oncoming vehicle is recognised in good time, this will motivate drivers to keep their eyes on the road. The purpose of this paper is to present an approach to detect vehicles at night based on the employment of a single onboard camera. This system is based on detecting vehicle headlights (...) by recognising their shapes via an SVM classifier which was trained for this purpose. A pairing algorithm was designed to pair vehicle headlights to ensure that the two headlights belong to the same vehicle. A multi-object tracking algorithm was invoked to track the vehicle throughout the time the vehicle is in the scene. The system was trained with 503 single objects and tested using 144 587 single objects which were extracted from 1410 frames collected from 15 videos and 27 moving vehicles. It was found that the accuracy of recognition was 97.9% and the vehicle recognition rate was 96.3% which indicates clearly the high robustness attained by this system. (shrink)

Patrick Suppes' set-theoretical approach to the analysis of theories, and Joseph D. Sneed's metatheory are briefly outlined. The notions of observation, illusion and hallucination are reconstructed according to these approaches. It is argued that the terms ‘perception’ and ‘truth’ are theoretical with respect to observation but nontheoretical with respect to illusion and hallucination. Hallucination is construed as a special kind of illusion.

Social representations research is often undertaken by scholars who seek to ‘give voice’ to knowledge that are held by socially disenfranchised individuals and groups. However, this endeavour poses a number of problems in practice, not least because it assumes that the ‘voices’ voiced by individuals and/or groups in social research will be unambiguous and uniform, and unchanged by the research encounter. Despite the growth of attention to the critical potential of social representations theory, there remains a lack of scholarship on (...) the relationship between the theory's emphasis on the relational, or dialogical, nature of social life and the implications of this for critical research. In this article, I argue that the dialogical epistemology from which social representations research must depart incites reflection upon the design of empirical studies, which must equally attend to both ‘Ego’ and ‘Alter’, and the researcher-researched relationship, which may itself be best viewed as an Ego-Alter interaction. I make the case for adopting dialogical epistemology in critical social psychology, and argue that this is essential to undertaking ethical social research. I conclude by suggesting that claims to ‘giving voice’ have little place in critical social psychology in general, and social representations scholarship in particular. (shrink)

Practical Mysticism in Islam and Christianity offers a comparative study of the works of the Sufi-poet Jalal al-Din Rumi (1207-1273) and the practical teachings of the German Dominican, Meister Eckhart (c1260-1327/8). Rumi has remained an influential figure in Islamic mystical discourse since the thirteenth century, while also extending his impact to the Western spiritual arena. However, his ideas have frequently been interpreted within the framework of other mystical, philosophical, or religious systems. Through its novel approach, this book aims to reformulate (...) Rumi's practical mysticism by employing four methodological principles: a) mysticism is a coherent structure with mutual interconnection between its parts; b) the imposition of alien structures to interpret any particular mysticism damages its inward coherency; c) practical mysticism consists of two main parts, namely practices and stages; and d) the proper use of comparative methodology enables a deeper understanding of each juxtaposed system. Eckhart's speculative mysticism, which differs from and enjoys similarities with the love-based mysticism of Rumi, provides a "mirror" that highlights the special features of Rumi's practical mysticism. Such comparison also allows a deeper comprehension of Eckhart's practical thought. Offering a critical examination of practical mysticism, this book is a valuable resource for students and scholars of Islamic studies, comparative mysticism, and the intellectual history of Islam.

The rate of human health care-associated infections caused by Acinetobacter baumannii has increased significantly in recent years for its remarkable resistance to desiccation and most antibiotics. Phospholipases, capable of destroying a phospholipid substrate, are heterologous group of enzymes which are believed to be the bacterial virulence determinants. There is a need for in silico studies to identify potential vaccine candidates. A. baumannii phospholipase D role has been proved in increasing organism’s resistance to human serum, destruction of host epithelial cell and (...) pathogenesis in murine model. In this in silico study high potentials of A. baumannii PLD in elicitation of humoral and cellular immunities were elucidated. Thermal stability, long half-life, non-similarity to human and gut flora proteome and non-allergenicity were in a list of A. baumannii PLD positive properties. Potential epitopic sequences were also identified that could be used as peptide vaccines against A. baumannii and various other human bacterial pathogens. (shrink)

ZusammenfassungWas ist praktisches Wissen?Die Diskussion über diese Frage hat sich in den letzten Jahrzehnten darauf konzentriert, das praktische Wissen als ein Wissen- wie aufzufassen. Im Folgenden wird eine weitere Differenzierung dieser Ansicht vorgenommen, indem durch eine Analyse der Syntax des klinischpraktischen Wissens dafür geworben wird, dieses Wissen als eine Kategorie von bedingten Geboten für das ärztliche Handeln in der klinischen Entscheidungsfindung zu betrachten. Syntaktisch gesehen, sind diese Gebote deontische Normen („conditional obligations“). Da sie durch die diagnostisch-therapeutische Forschung (= klinische Forschung) (...) aufgestellt und erforscht werden, muss die klinische Forschung als eine deontische Disziplin angesehen werden. Sie ist deshalb dem Bereich der normativen Ethik zuzuordnen. Im direkten Zusammenhang damit ist die klinische Praxis – als eine überzeitliche Institution, nicht als das Handeln von Einzelpersonen – als praktizierte Moral im Dienste der Menschen („Karitas“) einzustufen, weil sie aus dem Versuch besteht, jene Gebote umzusetzen.
