Multi-Viewer Display Environments (MVDE) provide unique opportunities to present personalized information to several users concurrently in the same physical display space. MVDEs can support correct 3D visualizations to multiple users, present correctly oriented text and symbols to all viewers and allow individually chosen subsets of information in a shared context. MVDEs aim at supporting collaborative visual analysis, and when used to visualize disjoint information in partitioned visualizations they even necessitate collaboration. When solving visual tasks collaboratively in a MVDE, overall performance is affected not only by the inherent effects of the graphical presentation but also by the interaction between the collaborating users. We present results from an empirical study where we compared views with lack of shared visual references in disjoint sets of information to views with mutually shared information. Potential benefits of 2D and 3D visualizations in a collaborative task were investigated and the effects of partitioning visualizations both in terms of task performance, interaction behavior and clutter reduction. In our study of a collaborative task that required only a minimum of information to be shared, we found that partitioned views with a lack of shared visual references were significantly less efficient than integrated views. However, the study showed that subjects were equally capable of solving the task at low error levels in partitioned and integrated views. An explorative analysis revealed that the amount of visual clutter was reduced heavily in partitioned visualization, whereas verbal and deictic communication between subjects increased. It also showed that the type of the visualization (2D/3D) affects interaction behavior strongly. An interesting result is that collaboration on complex geo-time visualizations is actually as efficient in 2D as in 3D.

Interest in the biological role of bioactive compounds present in medicinal herbs has increased over the last years. Of particular interest are plants that have an anti-Alzheimer activities. Several plants can be useful for Alzheimer (AD) management. Such as these which have anti-inflammatory activity, acetylcholinesterase (AChE) inhibitory action, antiapoptotic, slow the aggregation of amyloid peptide and antioxidant activities. Grape seed extract (GSE) is a complex mixture of several compounds, mostly represented by polyphenols and flavonoids. Their consumption is safe and is recognized to exert several health benefits. GS flavonoids have been associated with the reduced risk of chronic diseases, we present some findings on the potential benefits of GSE for the treatment of AD.

Cardiovascular diseases (CVDs) are the most common cause of morbidity and mortality worldwide. The potential benefits of natural antioxidants derived from supplemental nutrients against CVDs are well known. Remarkably, natural antioxidants exert cardioprotective effects by reducing oxidative stress, increasing vasodilation, and normalizing endothelial dysfunction. Recently, considerable evidence has highlighted an important role played by the synergistic interaction between endothelial nitric oxide synthase (eNOS) and sirtuin 1 (SIRT1) in the maintenance of endothelial function. To provide a new perspective on the role of natural antioxidants against CVDs, we focused on microRNAs (miRNAs), which are important posttranscriptional modulators in human diseases. Several miRNAs are regulated via the consumption of natural antioxidants and are related to the regulation of oxidative stress by targeting eNOS and/or SIRT1. In this review, we have discussed the specific molecular regulation of eNOS/SIRT1-related endothelial dysfunction and its contribution to CVD pathologies; furthermore, we selected nine different miRNAs that target the expression of eNOS and SIRT1 in CVDs. Additionally, we have summarized the alteration of miRNA expression and regulation of activities of miRNA through natural antioxidant consumption.

Background: Digital health solutions targeting diabetes self-care are popular and promising, but important questions remain about how these tools can most effectively help patients. Consistent with evidence of the salutary effects of note-taking in education, features that enable annotation of structured data entry might enhance the meaningfulness of the interaction, thereby promoting persistent use and benefits of a digital health solution. Method: To examine the potential benefits of note-taking, we explored how patients with type 2 diabetes used annotation features of a digital health solution and assessed the relationship between annotation and persistence in engagement as well as improvements in glycated hemoglobin (A1C). Secondary data from 3142 users of the BlueStar digital health solution collected between December 2013 and June 2017 were analyzed, with a subgroup of 372 reporting A1C lab values. Results: About a third of patients recorded annotations while using the platform. Annotation themes largely reflected self-management behaviors (diet, physical activity, medication adherence) and well-being (mood, health status). Early use of contextual annotations was associated with greater engagement over time and with greater improvements in A1C. Conclusions: Our research provides preliminary evidence of the benefits of annotation features in a digital health solution. Future research is needed to assess the causal impact of note-taking and the moderating role of thematic content reflected in notes.

Drones are increasingly understood and imagined as important actors, inhabiting and transforming aerial space. From their entrenched establishment within battlefield operations, drones have spawned into a diverse ecosystem of platforms and applications, increasingly punctuating domestic urban airspace. While occupying a status as exemplars of urban innovation, the drone poses, and remains bound to, a range of techno-cultural contestations – from challenges around airspace integration, to concerns around privacy, safety and pollution. Thinking with commercial drone futures, and specifically the logistics sector, this article interrogates the role of speculation in this unfolding techno-landscape. In so doing we turn to two key sites through which the drone is anticipated – namely patents and adverts – as lenses through which to investigate projected visualisations underpinning the emergent, envisioned and anticipated drone. We argue that such drone speculations do not simply and solely envision new means of circulating goods, people and information, but rather embody and act to promote a particular set of aerial desires and social relations. Critically unpacking envisioned notions of frictionless mobility, instant consumption, and the appropriation of vertical spaces and spectra, we argue that such speculative sites and practices importantly participate in a techno-fetishist agenda positing drone technology as a privileged and panacea agent of futurity, while often eliding its implications.<br /><br />Key messages<br /><ul><li>Drones are increasingly understood and imagined as important actors, inhabiting and transforming urban airspace.</li><br /><li>Interrogating the domestic drone, we offer a critical visual analysis of key sites through which it is speculated.</li><br /><li>While envisioning convenience from the air, commercial drone speculations also embody and promote particular aerial desires.</li><br /><li>We argue that staying with speculation enables the critical unpacking of notions of frictionless mobility, instant consumption and the appropriation of vertical space.</li></ul>

Youth exchanges have become an essential component of people-to-people exchanges in international relations, both in bilateral and multilateral formats. This paper analyses the participation of Russia and its Central Asian partners (Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan) in youth exchanges in the Shanghai Cooperation Organisation. The authors consequently discuss the institutional structure and formats of the multilateral cooperation, its development within the last decade, and the representation and role of the member states. The research is based on the study of the SCO multilateral documents, SCO institutions’ documentation, official addresses and interviews of the SCO politicians and NGO leaders, online news archives of NGOs and media. The authors conclude that the SCO has formed a multilateral cooperation mechanism for youth exchanges, in which Russia and Central Asia are fully represented, with minor exclusions. Meanwhile, the cooperation demonstrates the evident rivalry between Russia and China in this cooperation. The Central Asian countries have become subject to this rivalry, however, at the same time they have already started to put forward their own initiatives, too, which can be significant for the development of multilateral dialogue. Finally, the paper discusses the potential benefits of cooperation for its participants.

The Impact

In this article, I comment on the potential benefits and limitations of open science reforms for improving the transparency and accountability of research, and enhancing the credibility of research findings within communities of policy and practice. Specifically, I discuss the role of replication and reproducibility of research in promoting better quality studies, the identification of generalizable principles, and relevance for practitioners and policymakers. Second, I suggest that greater attention to theory might contribute to the impact of open science practices, and discuss ways in which theory has implications for sampling, measurement and research design. Ambiguities concerning the aims of preregistration and registered reports also are highlighted. In conclusion, I discuss structural roadblocks to open science reform and reflect on the relevance of these reforms for educational psychology.
