Collective intelligence (CI) is the ability of a group to solve a wide range of problems. Synchrony in nonverbal cues is critically important to the development of CI; however, extant findings are mostly based on studies conducted face-to-face. Given how much collaboration takes place via the internet, does nonverbal synchrony still matter and can it be achieved when collaborators are physically separated? Here, we hypothesize and test the effect of nonverbal synchrony on CI that develops through visual and audio cues in physically-separated teammates. We show that, contrary to popular belief, the presence of visual cues surprisingly has no effect on CI; furthermore, teams without visual cues are more successful in synchronizing their vocal cues and speaking turns, and when they do so, they have higher CI. Our findings show that nonverbal synchrony is important in distributed collaboration and call into question the necessity of video support.

The Face

Children with Rett Syndrome (RS) are reported to use multiple modalities to communicate although their intentionality is often questioned (Bartolotta, Zipp, Simpkins, & Glazewski, 2011; Hetzroni & Rubin, 2006; Sigafoos et al., 2000; Sigafoos, Woodyatt, Tuckeer, Roberts-Pennell, & Pittendreigh, 2000). This paper will present results of a study analyzing the unconventional vocalizations of a child with RS. The primary research question addresses the ability of familiar and unfamiliar listeners to interpret unconventional vocalizations as “yes” or “no” responses. This paper will also address the acoustic analysis and perceptual judgments of these vocalizations. Pre-recorded isolated vocalizations of “yes” and “no” were presented to 5 listeners (mother, father, 1 unfamiliar, and 2 familiar clinicians) and the listeners were asked to rate the vocalizations as either “yes” or “no.” The ratings were compared to the original identification made by the child's mother during the face-to-face interaction from which the samples were drawn. Findings of this study suggest, in this case, the child's vocalizations were intentional and could be interpreted by familiar and unfamiliar listeners as either “yes” or “no” without contextual or visual cues. The results suggest that communication partners should be trained to attend to eye-gaze and vocalizations to ensure the child's intended choice is accurately understood.

Central Claim

This book explores the value for literary studies of relevance theory, an inferential approach to communication in which the expression and recognition of intentions plays a major role. Drawing on a wide range of examples from lyric poetry and the novel, nine of the ten chapters are written by literary specialists and use relevance theory both as an overall framework and as a resource for detailed analysis. The final chapter, written by the co-founder of relevance theory, reviews the issues addressed by the volume and explores their implications for cognitive theories of how communicative acts are interpreted in context. Originally designed to explain how people understand each other in everyday face-to-face exchanges, relevance theory—described in an early review by a literary scholar as ‘the makings of a radically new theory of communication, the first since Aristotle’s’—sheds light on the whole spectrum of human modes of communication, including literature in the broadest sense. Reading Beyond the Code is unique in using relevance theory as a prime resource for literary study, and is also the first to apply the model to a range of phenomena widely seen as supporting an ‘embodied’ conception of cognition and language where sensorimotor processes play a key role. This broadened perspective serves to enhance the value for literary studies of the central claim of relevance theory: that the ‘code model’ is fundamentally inadequate to account for human communication, and in particular for the modes of communication that are proper to literature.

Digital holography is a very efficient technique for 3D imaging and the characterization of changes at the surfaces of objects. However, during the process of holographic interferometry, the reconstructed phase images suffer from speckle noise. In this paper, de-noising is addressed with phase images corrupted with speckle noise. To do so, DnCNN residual networks with different depths were built and trained with various holographic noisy phase data. The possibility of using a network pre-trained on natural images with Gaussian noise is also investigated. All models are evaluated in terms of phase error with HOLODEEP benchmark data and with three unseen images corresponding to different experimental conditions. The best results are obtained using a network with only four convolutional blocks and trained with a wide range of noisy phase patterns.

AbstractStudies in collective intelligence have shown that suboptimal cognitive traits of individuals can lead a group to succeed in a collective cognitive task, in recent literature this is called mandevillian intelligence. Analogically, as Mandeville has suggested, the moral vices of individuals can sometimes also lead to collective good. I suggest that this mandevillian morality can happen in many ways in collaborative activities. Mandevillian morality presents a challenge for normative virtue theories in ethics. The core of the problem is that mandevillian morality implies that individual vice is, in some cases, valuable. However, normative virtue theories generally see vice as disvaluable. A consequence of this is that virtue theories struggle to account for the good that can emerge in a collective. I argue that normative virtue theories can in fact accommodate for mandevillian emergent good. I put forward three distinctive features that allow a virtue theory to do so: a distinction between individual and group virtues, a distinction between motivational and teleological virtues, and an acknowledgement of the normativity of “vicious” roles in groups.

Abstract Background Enhancing self-efficacy to manage symptoms and functions is an important aspect of self-management for patients with knee osteoarthritis (OA). Many reports have investigated the effects of self-management education programmes for arthritis patients. However, a study that exclusively focuses on patients with OA in the same joints is required to clarify the effects of self-management programmes because individuals with knee OA experience physical and psychological difficulties different from those experienced by individuals with other arthritis diseases. Furthermore, previous studies have reported a wide range of delivery styles of self-management education programmes. This systematic review aimed to evaluate the effects of group-based and face-to-face self-management education programmes conducted by health professionals targeting self-efficacy for knee OA exclusively. Methods The MEDLINE, CENTRAL, EMBASE, CINAHL, Web of Science, and PEDro databases were searched to identify quantitative measures used in randomised controlled trials (RCTs) to assess the effects of self-management education programmes targeting self-efficacy in patients with knee OA. We included studies in which medical professional-delivered self-management education programmes were conducted in a group-based and face-to-face manner in community or outpatient settings. Results Seven RCTs from five countries were included in this review. Our retrieved studies included various types of self-management education programmes such as cognitive behavioural counselling, pain management education, physical education, weight management education, and arthritis self-efficacy management education, and control arms. They assessed various aspects of self-efficacy, including pain, physical function, arthritis symptoms excluding pain, weight management, mobility, and self-regulation. The total score of the Arthritis Self-Efficacy Scale was also measured. Some studies have reported beneficial effects of group-based and face-to-face self-management education programmes on self-efficacy for management of pain and other symptoms and for self-regulatory, knee OA. However, the results of the included studies were varied and inconsistent. Conclusions The current review only included seven studies, and there was a wide range of clinical heterogeneity among these studies. Thus, the effects of group-based and face-to-face self-management education programmes conducted by health professionals on self-efficacy for knee OA exclusively are inconclusive to date. Therefore, high-quality studies are required to provide significant information on clinicians, patients, and healthcare professionals in the future.

AbstractThe academic field of Qurʾānic Studies employs a wide range of approaches, each one of which helps to open up a new perspective on the Qurʾānic text. The Holy Book was revealed to guide people; it is thus of relevance to all aspects of people’s lives. This article focuses on the way social actors are represented in one Meccansūra, entitled “Ya-Sin”, and employs a case-study approach to do so. The analysis carried out includes the socio-semantic processes that thesūrauses in order to represent social actors either by behavior (action) or meaning (reflection), and it also analyzes the actors as they are represented in processes such as activation and passivation. The methodology adopted is eclectic and analytic. It is a hybrid of Swales’ move analysis, El-Awa’s identification of shift-markers, and Halliday’s and Van Leeuwen’s theories of social actor representation. This study shows how such an analysis can contribute to understanding the apparently fragmented and non-linear nature of “Ya-Sin”.

The beta-3 adrenergic receptor (β3-AR) is by far the least studied isotype of the beta-adrenergic sub-family. Despite its study being long hampered by the lack of suitable animal and cellular models and inter-species differences, a substantial body of literature on the subject has built up in the last three decades and the physiology of β3-AR is unraveling quickly. As will become evident in this work, β3-AR is emerging as an appealing target for novel pharmacological approaches in several clinical areas involving metabolic, cardiovascular, urinary, and ocular disease. In this review, we will discuss the most recent advances regarding β3-AR signaling and function and summarize how these findings translate, or may do so, into current clinical practice highlighting β3-AR’s great potential as a novel therapeutic target in a wide range of human conditions.

Mode II shear fracture process can be observed in plain-concrete structures exposed to intensive loadings such as shock, blasting or projectile-impact. It is the reason why the quasi-static and dynamic shear fracturing properties of concrete need to be investigated. In previous works performed by Forquin and coauthors a passive confining cell was applied to PTS (Punch-Through-Shear) specimens in a similar way than in quasi-oedometric compression tests where metallic ring are used as passive confinement. However the change of confining level during the sample loading constitutes a main drawback of this technique. In the present work a novel testing method is proposed based on a pre-stressing of the sample. To do so, the concrete specimen is inserted into pre-stressed metallic cell. During the unloading stage confining stresses are transferred to the ligament of the sample. In a second stage, a differential displacement applied to the central part of the sample toward the side parts produces a shearing of the ligament. The experiments performed in static and dynamic conditions (SHPB testing) allow the shear response of concrete to be determined over a wide range of strain-rates. In the present communication, the testing technique and obtained results are compared to the obtained data with the previous experimental method.
