Although laughter plays an essential part in emotional vocal communication, little is known about the acoustical correlates that encode different emotional dimensions. In this study we examined the acoustical structure of laughter sounds differing along four emotional dimensions: arousal, dominance, sender's valence, and receiver-directed valence. Correlation of 43 acoustic parameters with individual emotional dimensions revealed that each emotional dimension was associated with a number of vocal cues. Common patterns of cues were found with emotional expression in speech, supporting the hypothesis (...) of a common underlying mechanism for the vocal expression of emotions. (shrink)

The coronavirus disease pandemic fundamentally disrupted humans’ social life and behavior. Public health measures may have inadvertently impacted how people care for each other. This study investigated prosocial behavior, its association well-being, and predictors of prosocial behavior during the first COVID-19 pandemic lockdown and sought to understand whether region-specific differences exist. Participants from eight regions clustering multiple countries around the world responded to a cross-sectional online-survey investigating the psychological consequences of the first upsurge of lockdowns in spring 2020. Prosocial behavior (...) was reported to occur frequently. Multiple regression analyses showed that prosocial behavior was associated with better well-being consistently across regions. With regard to predictors of prosocial behavior, high levels of perceived social support were most strongly associated with prosocial behavior, followed by high levels of perceived stress, positive affect and psychological flexibility. Sociodemographic and psychosocial predictors of prosocial behavior were similar across regions. (shrink)

Este artigo baseia-se na ideia de que em qualquer tipo de diálogo os interlocutores estão marcados pela sua própria cultura/identidade. E também assim é no caso do diálogo inter-religioso. A cultura/identidade é o contexto existencial básico a partir do qual as pessoas entendem, questionam e interpretam as suas vidas, pelo que não pode ser ignorado. A necessidade de trabalhar no desenvolvimento das competências interculturais e na sensibilidade cultural surge como um ponto de partida fundamental para avançar neste tipo de diálogo. (...) This article is based on the idea that in any kind of dialogue the partners are marked by their own culture/identity. This is also the case of inter-religious dialogue. Culture/identity is the basic existential context from which people understand, raise questions and interpret their lives, can't be ignored. There is a need to work on developing cultural sensitivity and intercultural competencies as a fundamental starting point to advance in this type of dialogue. (shrink)

Kv10.1 is a voltage‐gated potassium channel relevant for tumor biology, but the underlying mechanism is still unclear. We propose that Kv10.1 plays a role coordinating primary cilium disassembly with cell cycle progression through localized changes of membrane potential at the ciliary base. Most non‐dividing cells display a primary cilium, an antenna‐like structure important for cell physiology. The cilium is disassembled when the cell divides, which requires an increase of Ca2+ concentration and a redistribution of phospholipids in its basal region, both (...) of which would be facilitated by local hyperpolarization. Cells lacking Kv10.1 show impaired ciliary disassembly and delayed entrance into mitosis. Kv10.1 is predominantly expressed during G2/M, a critical period for ciliary resorption, and localizes to the ciliary base and vesicles associated with the centrosome. This could explain the influence of Kv10.1 in cell proliferation, as well as phenotypic features of patients carrying gain of function mutations in the gene. (shrink)

This study investigated potential risk factors (coping, perfectionism and self-regulation) for substantial injuries in contemporary dance students using a prospective cohort design, as high-quality studies focusing on mental risk factors for dance injuries are lacking. Student characteristics (age, sex, BMI, educational program and history of injury) and psychological constructs (coping, perfectionism and self-regulation) were assessed using the Performing artist and Athlete Health Monitor (PAHM), a web-based system. Substantial injuries were measured with the Oslo Sports Trauma Research Center (OSTRC) Questionnaire on (...) Health Problems and recorded on a monthly basis as part of the PAHM system. Univariate and multivariate logistic regression analyses were conducted to test the associations between potential risk factors (i.e. student characteristics and psychological constructs) and substantial injuries. 99 students were included in the analyses. During the academic year 2016-2017, 48 students (48.5%) reported at least one substantial injury. Of all factors included, coping skills (OR: 0.91; 95% CI: 0.84–0.98), age (OR: 0.67; 95% CI: 0.46–0.98) and BMI (OR: 1.38; 95% CI: 1.05–1.80) were identified as significant risk factors in the multivariate analysis. The model explained 24% of the variance in the substantial injury group. Further prospective research into mental risk factors for dance injuries with larger samples sizes is needed to develop preventive strategies. Yet, dance schools could consider including coping skills training as part of injury prevention programs and, perhaps, providing special attention to younger dancers and those with a higher BMI through transitional programs to assist them in managing the stress they experience throughout their (academic) career.

Cortical stimulation has been used for brain mapping for over a century, and a standard assumption is that stimulation interferes with task execution due to local effects at the stimulation site. Stimulation can however produce afterdischarges which interfere with functional localization and can lead to unwanted seizures. We previously showed that cognitive effort can terminate these afterdischarges, when termination thus occurs, there are electrocorticography changes throughout the cortex, not just at sites with afterdischarges or sites thought functionally important for the (...) cognitive task used, and thresholds for afterdischarges and functional responses can change among stimulation trials. We here show that afterdischarge termination can occur prior to overt performance of the cognitive tasks used to terminate them. These findings, taken together, demonstrate that task-related brain changes are not limited to one or a group of functional regions or a specific network, and not limited to the time directly surrounding overt task execution. Discrete locations, networks and times importantly underpin clinical behaviors. However, brain activity that is diffuse in location and extended in time also affect task execution and can affect brain mapping. This may in part reflect fluctuating levels of attention, engagement, or motivation during testing. (shrink)

Formal accounts of negotiation tend to invoke the strategic models of conflict which have been impressively developed by game theorists in this half-century. For two decades, however, research on artificial intelligence (AI) has produced a different formal picture of the agent and of the rational deliberations of agents. AI's models are not based simply on intensities of preference and quantities of probability. AI's models consider that agents use language in various ways, that agents use and convey knowledge, that agents plan, (...) search, focus, and argue. Agents can choose their language, apply their knowledge, change their plans, continue their search, shift their focus, and rebut another's arguments. (shrink)

_341_ _Objectives: _In patients with multivessel disease both the detection of the culprit lesion and the exact allocation are important preconditions for sufficient treatment and improved outcome. In a vessel based approach the combination of quantitative coronary angiography and fractional flow reserve measured by a pressure wire should be advantageous compared to myocardial SPECT, as morphological and functional information is delivered simultaneously. Therefore our aim was to evaluate MS in the detection and allocation of hemodynamically significant stenoses obtained by the (...) combined gold standard QCA plus FFR in patients with multivessel disease. _Methods: _FFR and QCA of 95 vessels in 80 patients have been evaluated. Hemodynamically significant target lesions were defined as intermediate stenoses between 50 and 75% with an FFR. (shrink)

In the postmodern era the impact media have on our lives is continuously growing. Not only do media reflect reality, but they also shape and reconstruct it according to the public's hopes, fears or fantasies. Reality itself is not the sum of all objective processes and things, but it is socially constructed by the discourses that reflect and produce power. On the other hand, the public does not simply accept or reject the media messages, but interprets them according to its (...) social background (Zoonen, 1994, p. 41). My interest lies in identifying how are women represented in the media and what are the dominant images of femininity, as well as the alternative ones. There is a strong connection between image and identity as the latter can not be constructed without the former. Basically, the postmodern subject has been reduced to an image, therefore the image plays an important part in constructing the feminine identity. (shrink)

BackgroundThere is evidence that direct journal endorsement of reporting guidelines can lead to important improvements in the quality and reliability of the published research. However, over the last 20 years, there has been a proliferation of reporting guidelines for different study designs, making it impractical for a journal to explicitly endorse them all. The objective of this study was to investigate whether a decision tree tool made available during the submission process facilitates author identification of the relevant reporting guideline.MethodsThis was (...) a prospective 14-week before–after study across four speciality medical research journals. During the submission process, authors were prompted to follow the relevant reporting guideline from the EQUATOR Network and asked to confirm that they followed the guideline (‘before’). After 7 weeks, this prompt was updated to include a direct link to the decision-tree tool and an additional prompt for those authors who stated that ‘no guidelines were applicable’ (‘after’). For each article submitted, the authors’ response, what guideline they followed (if any) and what reporting guideline they should have followed (including none relevant) were recorded.ResultsOverall, 590 manuscripts were included in this analysis—300 in the before cohort and 290 in the after. There were relevant reporting guidelines for 75% of manuscripts in each group; STROBE was the most commonly applicable reporting guideline, relevant for 35% (n = 106) and 37% (n = 106) of manuscripts, respectively. Use of the tool was associated with an 8.4% improvement in the number of authors correctly identifying the relevant reporting guideline for their study (p < 0.0001), a 14% reduction in the number of authors incorrectly stating that there were no relevant reporting guidelines (p < 0.0001), and a 1.7% reduction in authors choosing a guideline (p = 0.10). However, the ‘after’ cohort also saw a significant increase in the number of authors stating that there were relevant reporting guidelines for their study, but not specifying which (34 vs 29%; p = 0.04).ConclusionThis study suggests that use of a decision-tree tool during submission of a manuscript is associated with improved author identification of the relevant reporting guidelines for their study type; however, the majority of authors still failed to correctly identify the relevant guidelines.

Open peer commentary on the article “What Can the Global Observer Know?” by Diana Gasparyan. Upshot: From the standpoint of epistemology-centered operationalist, pragmatist, constructivist perspectives, which are firmly grounded in the capacities of limited observers, all omniscient observers in realist ontologies and theologies appear both completely unattainable in practice and conceptually incoherent in their formulations. Nevertheless, these ideas may be useful heuristically.

Open peer commentary on the article “What Can the Global Observer Know?” by Diana Gasparyan. Upshot: Even well-founded criticism of the notion of the global observer does not immediately challenge contemporary metaphysical realism. A viable alternative to the latter, and to far-reaching constructivist positions on the other side, originates in replacing global observation with actual and possible local observations.

Brigitte Lion and Diana Stein have, in The Tablets from the Temple Precinct at Nuzi, joined forces to edit the texts of the sixty-nine Nuzi texts found in temples and to publish and edit their 282 seal impressions. This masterful collaboration excels in many areas, including in-depth prosopographical analysis and thorough integration of the local seal practice into the orbit of textual analysis. This volume sets a standard of text edition and analysis that dwarfs the achievements of the students (...) of Nuzi from the first two-thirds of the twentieth century and even since. Nevertheless, the raison d’être of this heterogeneous group of texts in the context of their storage in temples remains enigmatic. (shrink)

L’ouvrage se présente comme un commentaire continu des chapitres de la Physique d’Aristote consacrés à l’étude du lieu (IV, 1-5). Le texte grec est cité d’après l’édition de Ross, et traduit par l’auteure de manière toujours très précise et rigoureuse (si ce n’est l’introduction d’une négation indue à la ligne 212a31, p. 237). L’ensemble permet de se donner une bonne conception de l’importance qu’Aristote accorde au lieu pour expliquer le mouvement des corps, de sa différence avec la notion d...

How is women’s conception of self affected by the caregiving responsibilities traditionally assigned to them and by the personal vulnerabilities imposed on them? If institutions of male dominance profoundly influence women’s lives and minds, how can women form judgments about their own best interests and overcome oppression? Can feminist politics survive in face of the diversity of women’s experience, which is shaped by race, class, ethnicity, and sexual orientation, as well as by gender? Exploring such questions, leading feminist thinkers have (...) reinvigorated work on the concept of self and personal identity, as demonstrated by the discussions in this insightful volume.The concerns that animate feminist scholarship have prompted feminist philosophers to sideline the theme of individualism and to focus on the theme of intersubjectivity. In conceptualizing the self, the contributors to this volume highlight emotional bonds among people, the stories people tell one another, and the systems of categories and behavioral norms that unite and divide groups of people. Topics addressed include sexual violence and the self, the social self and autonomy, the narrative self and integrity, self-ownership and the body, forgetting yourself and your race, group membership and personal identity, grief and gender, sympathy and women’s diversity, emotion and emancipatory epistemology, and dependency and justice. This volume will be important reading for students of feminist theory, ethics, and social and political philosophy. (shrink)

This book tackles how and why 'landscape' (farms, gardens, countryside) set the scene in the first centuries BCE and CE for Romans keen to talk up and about (but also to scrutinize and understand) what it meant to be a citizen. It investigates what 'landscape' means now and reflects upon how contemporary approaches to 'landscape' can enrich our understanding of ancient experience of the interface between natural and artificial space. It encourages examination of 'landscape' from a range of angles, suggesting (...) alternative ways of thinking about what landscape represents. These methodological approaches (presented initially via a set of key terms and definitions and then deployed thematically across four chapters), combined with a detailed interdisciplinary bibliography and a series of case studies of literary texts and material sites, enable readers to use this survey as a starting point for developing their own in-depth study.
