ABSTRACT Purpose To explore the relationship between the two components of spontaneous speech in the Brief Aphasia Evaluation (BAE) and the rest of the scale represented by its three main factors: The Expression, Comprehension, and Complementary factors. Methods BAE has proven validity and reliability. The evaluation of spontaneous speech in this scale comprises two components: Performance Rank (score: 0-3) and Type of Disorder (Fluency [F], Content [C], or Mixed [FC]) when rank < 3. Sixty-seven patients with left brain damage and 30 demographically matched healthy participants (HP) were studied. It was analyzed the correlation between Performance Rank and the three BAE factors and, recoding 3 as 0 and < 3 as 1, the sensitivity/specificity of this component for each factor. The effect of Type of Disorder on the three factors was analyzed. Results 1) Performance Rank: Correlations of 0.84 (Expression), 0.81 (Comprehension), and 0.76 (Complementary) were observed, with a sensitivity and specificity ≥ 78% for any factor; 2) Type of Disorder: The performance significantly decreased from FC to C and from C to F in Expression (FC < C < F), from FC to C and from FC to F also in Comprehension and Complementary, from patients with any type of disorder to HP. Conclusion Performance Rank was a relevant indicator of aphasia by its consistency with valid and comprehensive dimensions of acute language impairments. A degree difference between F and C was observed, being F a milder disorder; i.e., fluency problems were less severe than retrieval or anomia ones.

Abstract: We recorded reaction times (RTs) and event-related potentials (ERPs) in patients with unilateral lesions during a memory search task. Participants memorized faces or abstract words, which were then recognized among new ones. The RT deficit found in patients with left brain damage (LBD) for words increased with memory set size, suggesting that their problem relates to memory search. In contrast, the RT deficit found in patients with RBD for faces was apparently related to perceptual encoding, a conclusion also supported by their reduced P100 ERP component. A late slow wave (720-1720 ms) was enhanced in patients, particularly to words in patients with LBD, and to faces in patients with RBD. Thus, the slow wave was largest in the conditions with most pronounced performance deficits, suggesting that it reflects deficit-related resource recruitment.

Summary: Our meta-analysis focused on the relationship between homocysteine (Hcy) level and the incidence of aneurysms and looked at the relationship between smoking, hypertension and aneurysms. A systematic literature search of Pubmed, Web of Science, and Embase databases (up to March 31, 2020) resulted in the identification of 19 studies, including 2,629 aneurysm patients and 6,497 healthy participants. Combined analysis of the included studies showed that number of smoking, hypertension and hyperhomocysteinemia (HHcy) in aneurysm patients was higher than that in the control groups, and the total plasma Hcy level in aneurysm patients was also higher. These findings suggest that smoking, hypertension and HHcy may be risk factors for the development and progression of aneurysms. Although the heterogeneity of meta-analysis was significant, it was found that the heterogeneity might come from the difference between race and disease species through subgroup analysis. Large-scale randomized controlled studies of single species and single disease species are needed in the future to supplement the accuracy of the results.

The Relationship

Using a resource-based view and dynamic capabilities approach, this study investigates both the internal and external factors influencing competitive advantage in the hotel industry. For this purpose, we examine how organizational capabilities may lead to customer relationship building and in turn to competitive advantage. We further test the moderation role of market dynamism on the relationship between organizational capabilities and customer relationship building, and also investigate the mediation effect of customer relationship building on the association between organizational capabilities and competitive advantage. A questionnaire-based study was conducted among hotel employees in Northern Cyprus to test the conceptual model. A set of approaches was applied to detect common method bias and test the validity and reliability of the questionnaire. Correlation and regression analyses were conducted to evaluate the relationships between the variables, and bootstrapping analysis was applied to assess the mediation and moderation effects. The results revealed that organizational capabilities enhance customer relationship building and competitive advantage. Market dynamism as an external factor moderates the relationship between organizational capabilities and customer relationship building. There is also an indirect association between organizational capabilities and competitive advantage through the mediation of customer relationship building. The theoretical and practical implications of the findings are discussed.

AbstractThere is a steadily growing number of mobile communication systems that provide spatially encoded tactile information to the humans’ torso. However, the increased use of such hands-off displays is currently not matched with or supported by systematic perceptual characterization of tactile spatial discrimination on the torso. Furthermore, there are currently no data testing spatial discrimination for dynamic force stimuli applied to the torso. In the present study, we measured tactile point localization (LOC) and tactile direction discrimination (DIR) on the thoracic spine using two unisex torso-worn tactile vests realized with arrays of 3 × 3 vibrotactile or force feedback actuators. We aimed to, first, evaluate and compare the spatial discrimination of vibrotactile and force stimulations on the thoracic spine and, second, to investigate the relationship between the LOC and DIR results across stimulations. Thirty-four healthy participants performed both tasks with both vests. Tactile accuracies for vibrotactile and force stimulations were 60.7% and 54.6% for the LOC task; 71.0% and 67.7% for the DIR task, respectively. Performance correlated positively with both stimulations, although accuracies were higher for the vibrotactile than for the force stimulation across tasks, arguably due to specific properties of vibrotactile stimulations. We observed comparable directional anisotropies in the LOC results for both stimulations; however, anisotropies in the DIR task were only observed with vibrotactile stimulations. We discuss our findings with respect to tactile perception research as well as their implications for the design of high-resolution torso-mounted tactile displays for spatial cueing.

<p>The current study examined the relationship between university students’ academic identity and their perceptions of their parents’ parenting styles among a sample of Omani students. Marcia’s (1993) academic identity statuses are adapted. These are moratorium, foreclosed, diffuse, and achievement. Parenting styles included authoritative, authoritarian, and permissive. The participants were 192 undergraduate students from Oman. The participants responded to Arabic versions of the Academic Identity Status (Was &amp; Isaacson, 2008) and the Parenting Authority Questionnaire (Buri, 1991). Both questionnaires showed reasonable evidence of validity and reliability. The findings show that parenting styles varied in their relationship with the four statuses of students’ academic identity. Using the three parenting styles as predictors in the regression models, the lowest percentage of explained variance among identity dimensions was found for moratorium, while the highest explained variance was found for diffusion. Implications and future research are discussed and presented by the end of the paper.</p>

BACKGROUND: Facial responses to pain are believed to be an act of communication and, as such, are likely to be affected by the relationship between sender and receiver.OBJECTIVES: To investigate this effect by examining the impact that variations in communicative relations (from being alone to being with an intimate other) have on the elements of the facial language used to communicate pain (types of facial responses), and on the degree of facial expressiveness.METHODS: Facial responses of 126 healthy participants to phasic heat pain were assessed in three different social situations: alone, but aware of video recording; in the presence of an experimenter; and in the presence of an intimate other. Furthermore, pain catastrophizing and sex (of participant and experimenter) were considered as additional influences.RESULTS: Whereas similar types of facial responses were elicited independent of the relationship between sender and observer, the degree of facial expressiveness varied significantly, with increased expressiveness occurring in the presence of the partner. Interestingly, being with an experimenter decreased facial expressiveness only in women. Pain catastrophizing and the sex of the experimenter exhibited no substantial influence on facial responses.CONCLUSION: Variations in communicative relations had no effect on the elements of the facial pain language. The degree of facial expressiveness, however, was adapted to the relationship between sender and observer. Individuals suppressed their facial communication of pain toward unfamiliar persons, whereas they overtly displayed it in the presence of an intimate other. Furthermore, when confronted with an unfamiliar person, different situational demands appeared to apply for both sexes.
