Authors: Shi Lisong , Uy Chunkit , Huang Shih K , Yang Zifeng , Huang George PG , Wen Chihyung
Published: September 2016

The aim of current research work on micro air vehicles is to realize their autonomous control, i.e. building a library for a lookup table that would apply to micro electronics. In doing so, comprehensive flight tests need to be carried out. In this study, a four-wing flapping MAV is built and a multi-discipline approach is used to design the MAV model. Precision manufacturing technology is introduced here. The finished micro air vehicle has a weight of 8 g and is tested for flight by remote control. The micro air vehicle can perform both hovering and forward flight with high maneuverability. Forward flight is investigated first in this paper. Particle image velocimetry system is employed to examine unsteady aerodynamic performance in selected flight conditions. The study reveals that the micro air vehicle model will provide enough lift at a 30° angle of attack and flapping frequency of 12 Hz, which is consistent with real-life forward flight observations.
Hope Comes in Many Forms

Published: September 2016

In conflicts, political attitudes are based to some extent on the perception of the out-group as sharing the goal of peace and supporting steps to achieve it. However, intractable conflicts are characterized by inconsistent and negative interactions, which prevent clear messages of out-group support. This problem calls for alternative ways to convey support between groups in conflict. One such method is emotional expressions. The current research tested whether, in the absence of out-group support for peace, observing expressions of out-group hope induces conciliatory attitudes. Results from two experimental studies, conducted within the Israeli–Palestinian conflict, revealed support for this hypothesis. Expressions of Palestinian hope induced acceptance of a peace agreement through Israeli hope and positive perceptions of the proposal when out-group support expressions were low. Findings demonstrate the importance of hope as a means of conveying information within processes of conflict resolution, overriding messages of low out-group support for peace.
Explicit Associative Learning and Memory in Synesthetes and Nonsynesthetes
Authors: Bankieris Kaitlyn R. , Aslin Richard N.
Published: September 2016

Most current theories regarding the development of synesthesia focus on cross-modal neural connections and genetic underpinnings, but recent evidence has revitalized the potential role of associative learning. In the present study, we compared synesthetes’ and controls’ ability to explicitly learn shape-color pairings. Using a continuous measure of accuracy and multiple testing blocks, we found that synesthetes learned these pairings faster than controls. In a delayed retest, synesthetes outperformed controls, demonstrating enhanced long-term memory for shape–color associations. Following this retest, participants learned shuffled associations, and we found little evidence for group differences in subsequent learning ability. Overall, our findings support the hypothesis that synesthetes have exceptional associative learning abilities and further specify that this advantage pertains to the initial learning rate and long-term retention of associations.
Restricting mobile phone access during homework increases attainment of study goals
Authors: Cutino Chelsea M. , Nees Michael A.
Published: September 2016

Recent research has reported negative consequences, such as increased anxiety, associated with restricting people’s access to their mobile phones. These findings have led researchers to suggest that mobile phone use may pose a legitimately addictive behavior for some people. Other research has suggested negative effects of mobile phones on academic outcomes. To study the effects of phone separation on both anxiety and attainment of academic study goals, we randomly assigned participants ( N = 93) to a restricted mobile phone access condition or a control condition. After setting a list of goals for a study session, participants worked on their own, self-chosen class materials for 60 minutes. Anxiety was measured before and immediately following the study session. Attainment of study goals was assessed through a self-report estimate of the percent of study goals accomplished at the end of the session. We predicted that those who classified as high on a problematic mobile phone use scale and who had their phones taken away would show the greatest increases in anxiety over the session as well as the greatest deficits in attainment of study goals as compared to all other participants. While there was a general tendency for participants who scored higher on the problematic use scale to be more anxious, anxiety did not differ between participants with phone access and those without it. Participants without phone access self-reported attainment of 12% more of their study goals than those who had phones. This study qualified the conditions for which restricting mobile phone access increases anxiety and provided further empirical support for detriments to attainment of study goals when mobile phones are present.
Associations between psychological factors and the effect of home-based physical exercise in women with chronic neck and shoulder pain
Authors: Karlsson Linn , Gerdle Björn , Takala Esa-Pekka , Andersson Gerhard , Larsson Britt
Published: September 2016

Background:

Exercise is often used in the treatment of chronic neck and shoulder muscle pain. It is likely that psychological aspects have an impact on the results of exercise-based treatments.

Objectives:

(1) To examine the associations between psychological factors and the effect of a home-based physical exercise intervention. (2) To examine differences in psychological factors at baseline between (a) subjects who continued in the trial and those who did not and (b) subjects who completed the intervention and those who did not.

Method:

A total of 57 women with chronic neck and shoulder pain were included in a home-based exercise intervention trial. Pain intensity, disability, and psychological factors (anxiety and depression symptoms, catastrophizing, fear-avoidance beliefs, self-efficacy, and pain acceptance) were measured at baseline, after 4–6 months, and after 1 year of exercise. Associations between the psychological factors and changes in pain intensity and disability were analysed, as well as differences in psychological factors at baseline between subjects who continued in and completed the intervention, and those who did not.

Results:

Associations between positive changes in pain intensity and disability were found for low fear-avoidance beliefs and low-pain self-efficacy at baseline. In addition, fear-avoidance beliefs at baseline were higher in the subjects who dropped out of the intervention than in those who continued. Pain acceptance at baseline was higher in the subjects who completed the intervention at the end of the trial.

Conclusion:

Particularly, fear-avoidance beliefs and pain self-efficacy should be taken into consideration when implementing home-based physical exercise as treatment for chronic neck pain. In addition, high pain acceptance might improve the adherence to prescribed exercise.
Bargaining in the shadow of a commitment problem
Authors: Reed William , Clark David , Nordstrom Timothy , Siegel Daniel
Published: September 2016

This paper reports results from laboratory experiments on how commitment problems affect bargaining choices. Subjects are randomly assigned the conditions that produce a commitment problem in order to estimate the effect the commitment problem condition has on bargaining behavior. The empirical results suggest subjects are consistently responsive to the commitment problem condition. When presented with a commitment problem, most subjects identify the condition and choose the present day lottery over future negotiation. Moreover, subjects not exposed to the commitment problem condition bargain as if they were playing the one-stage ultimatum game. Subjects in both games are responsive to their own costs rather than their opponents, playing as if this complete information game were in an incomplete information setting.
Introduction: Spatial Big Data and everyday life
Authors: Leszczynski Agnieszka , Crampton Jeremy
Published: September 2016

Spatial Big Data—be this natively geocoded content, geographical metadata, or data that itself refers to spaces and places—has become a pervasive presence in the spaces and practices of everyday life. Beyond preoccupations with “the geotag” and with mapping geocoded social media content, this special theme explores what it means to encounter and experience spatial Big Data as a quotidian phenomenon that is both spatial, characterized by and enacting of material spatialities, and spatializing, configuring relations between subjects, objects, and spaces in new and unprecedented ways.
Public Engagement, Local Policies, and Citizens’ Participation: An Italian Case Study of Civic Collaboration
Authors: Bartoletti Roberta , Faccioli Franca
Published: September 2016

Since the 1990s, the theme of participation has come to the fore in international debates regarding at least three critical issues: the relationship between representative democracy and deliberative democracy and the possibility of citizens’ empowerment through their involvement in policy making; the role of communication and of digital media in promoting new forms of participation; the feeling of disaffection toward politics and of democratic deficit. What we observe is a proliferation of experiences of both bottom-up and top-down enhanced forms of civic engagement. Our article focuses on “ public engagement.” We analyze the civic collaboration policy promoted by the Municipality of Bologna (Italy) in the frame of “collaborative governance” of the commons, based on civic involvement and governance transparency. Civic collaboration is characterized by a mixed communication ecology. We focus on the inclusiveness of this form of public engagement with local policies and on the role of digital media in supporting citizen’s engagement. Civic collaboration emerges as a new, interesting frontier in top-down enhanced participation in local policies. We are currently witnessing some promising changes in the boundaries of participation, in civic practices and competencies. In conclusion, we argue that the concreteness of the projects of civic collaboration can enhance citizens’ trust in the municipal administration, but we wonder whether it is likely to become a substitute for fuller citizen participation in local governance and whether it could also foster a removal of the controversial dimension of the political.
Neighboring competitor? Indian image in Chinese media
Authors: Ji Deqiang , Hu Zhengrong , Muhammad Yousaf
Published: September 2016

Despite being two of the most populous and neighboring countries in the world, India and China have long been unfamiliar about each other. Although both of them are tagged as “emerging economic powers” in today’s world, China and India are much different in terms of political system, social structure, and cultural traditions. Owing to such differences and even prevalent stereotypes between the two countries, most of the information about them is channeled by their media systems. The review of literature presented in this article shows that the Chinese media and communication scholars are concerned more about Chinese media in India and not vice versa. As a reaction to this unbalanced literature, this article demonstrates a pilot content analysis of three different types of online news media in China, namely Sina News, Caixin Net, and Global Net. The major findings are as follows: Indian image on these media platforms is mainly negative, followed by neutral and positive. Among others, India–China relations, military expansion (some with territory/border issues), and oddities in the Indian society are most reported topics. Moreover, Indian portrayal by the online media is nationalist and defensive, being deemed as a “neighboring competitor,” and is subject to political or geopolitical agenda. All in all, the image of India presented by these Chinese online media platforms is a critical entry point for China’s self-reflection about its cultural ego-centrism, orientalism, and Westernizing political–economic modernization process. For a future with better mutual understanding and brighter China–India relations, this article offers a series of suggestions for both scholars and practitioners of different professions, including the epistemological revitalization of both countries’ geopolitical position in the Global South and in the grouping of emerging economies like Brazil, Russia, India, China and South Africa against the former Western dominant powers.

Published: September 2016

Multidrug-resistant enterococcal nosocomial invasive infections are a rising concern faced by the medical community. Not many options are available to treat these highly virulent organisms. Risk factors for developing these highly resistant organisms include prolonged hospital stay, previous antibiotic use, and immunosuppression. In this article, we report a case of daptomycin-resistant enterococcal native infective endocarditis treated with off-label use of quinupristin-dalfopristin.
Factors Associated with Returning At-Home Specimen Collection Kits for HIV Testing among Internet-Using Men Who Have Sex with Men
Authors: Ricca Alexandra V. , Hall Eric W. , Khosropour Christine M. , Sullivan Patrick S.
Published: September 2016

Background:

In the United States, men who have sex with men (MSM) are known to disproportionately have HIV. The authors sought to describe the acceptability of providing at-home dried blood spot specimen collection kits for HIV testing among MSM.

Methods:

Between August 2010 and December 2010, the authors recruited Internet-using, HIV-negative or -unknown MSM to participate in a 12-month study of behavioral risks. Eligible participants were mailed an at-home HIV test.

Results:

Of the 896 men who were sent a test kit, 735 (82%) returned the kit. Returning a test kit was significantly associated with race ( P = .002), highest level of education ( P = .012), and annual income ( P = .026). The adjusted odds of black, non-Hispanic men returning a test kit were about half of the odds of white, non-Hispanic men returning a test kit (adjusted odds ratios: 0.49; 95% confidence intervals: 0.31-0.78).

Conclusions:

Men who have sex with men are willing to provide biological specimens as part of an Internet-based HIV prevention study.
Conflict and Care

Published: September 2016

Israel has provided immediate healthcare to Syrian children, civilians and fighters since early 2013 despite being in an official state of war with Syria since 1973. We present qualitative findings from a larger mixed-methods phenomenological study to understand how the geopolitical and social history of Israel and Syria influences healthcare providers and Syrian patient caregivers in northern Israel. Theories of humanization and cognitive dissonance guided this study and frame the beliefs and experiences of healthcare providers who treated wounded Syrians in Israeli hospitals. Findings indicate healthcare providers and Syrian caregivers adjusted their beliefs to allow for positive healthcare experiences. Qualitative analysis revealed two major themes: supportive and hindering systemic elements contributing to the healthcare provider-patient-caregiver relationship. Internal psychological developments, contextual factors, and relational processes influenced humanization of the other within the relationship. This study illuminates unique ethical and humanitarian demands relevant for healthcare workers and those with whom they interact.
Bronchopulmonary Dysplasia in Preterm Infants Born at Less Than 32 Weeks Gestation
Authors: Xu Yan-Ping
Published: September 2016

Objectives: Bronchopulmonary dysplasia (BPD) is a chronic pulmonary disorder affecting preterm infants. We studied the factors and echocardiographic evidence of early pulmonary hypertension (PH) associated with moderate or severe BPD. Methods: We retrospectively reviewed preterm infants who were born at <32 weeks gestation and admitted to the neonatal intensive care unit at the Children’s Hospital of Zhejiang University School of Medicine between July 2013 and July 2015. Results: Forty-two preterm infants were enrolled in the study. All the patients received oxygen treatment for a mean of 62.5 ± 28.0 days. The grades of BPD were classified as follows: severe, 35.7%; moderate, 40.5%; and mild, 23.8%. The time of ventilator and oxygen supplementation was longer in infants who developed PH. Severe BPD was related to PH at 28 days. Conclusions: These findings support the notion that early pulmonary vascular disease and long-term infection in preterm infants contributes to increased susceptibility for severe BPD.
Saudi Arabia and the Iranian Nuclear Deal
Authors: Pasha A. K.
Published: September 2016

The signing of Joint Comprehensive Plan of Action (JCPOA) between Iran and the P5 + 1 countries (i.e., China, France, Russia, the United Kingdom, and the United States) heralds a new US foreign policy approach in the Middle East. Amidst growing signs of declining geopolitical influence in the region, the United States chose to end its three-decade-old tension with Iran. This has alarmed its traditional regional allies and partners, especially Israel and Saudi Arabia. While Israel had advocated a “military option” to stop Iranian nuclear ambitions and took the matters to the US Congress, Saudi Arabia preferred a less confrontationist approach due to its dependence upon the United States for security. Its reactions and the recent foreign policy choices underscore its anxiety over growing Iranian influence as well as its “interventionist” policy stoking instability in many Gulf and Arab states. In foreseeable future, both Saudi Arabia and Iran would have work for rapprochement and be content with their spheres of influence and continue depending on the United States to maintain stability and balance of power in the region.
Arab Factor as a Part of the Iranian–Israeli Conflict: An Israeli Perspective
Authors: Eilam Ehud
Published: September 2016

Arab states, mostly Syria, and non-state organizations such as Hamas and Hezbollah have been part of the Iranian–Israeli conflict. Israel stayed outside the civil war in Syria, without supporting the rebels or Bashar al-Assad and Hezbollah, which are Iran’s allies, that is, they oppose Israel. In Lebanon, there might be a clash between Israel and Hezbollah, particularly if Israel strikes Iran’s nuclear sites. Hamas is also an Iranian partner and an enemy of Israel. Yet the latter tolerates Hamas’ rule in the Gaza Strip for lack of a better choice.
The Effect of Community Pharmacy Technicians on Industry Standard Adherence Performance Measures After Cognitive Pharmaceutical Services Training
Authors: Justis Leanne , Crain Jeremy , Marchetti Merrill L. , Hohmeier Kenneth C.
Published: September 2016

Background: Cognitive pharmaceutical services (CPS) provided by pharmacists can improve patient adherence and industry standard performance measures. Community pharmacy technicians can aid in CPS support tasks on training, but it is unknown to what extent. Objective: To determine the effect of community pharmacy technicians on industry standard adherence performance measures after CPS training. Methods: Sixteen community pharmacy technicians within a supermarket chain division were chosen to participate in CPS training based on internal pharmacy benchmarking data. The training program consisted of 3 components: (1) classroom and (2) web-based training for medication therapy management platforms and (3) Hands-on in-pharmacy training. Researchers used pharmacy-specific EQuIPP reports of the proportion of days covered (PDC) for adherence related to diabetes, cholesterol, and hypertension to measure the primary outcome. September through October 2015 represented baseline data. November 2015 through March 2016 represented intervention data. Descriptive and inferential statistics were utilized for this retrospective analysis. The University of Tennessee Institutional Review Board classified the study exempt from review. Results: Overall, 100% of Cholesterol PDC 4-Star sites improved to a 5-Star score and 56% of sites improved in the Diabetes PDC score. All sites maintained a 5-Star score for RASA PDC postintervention. An average increase of 2.36% was observed for Cholesterol PDC across all sites. Possible lag time between the intervention and score improvements may limit relatability of results. Conclusions: This is the first study to report a positive trend between technician involvement in CPS and improvement in industry standard adherence performance measures. Further research capturing a longer time frame may be beneficial.
Internet-delivered treatment for older adults with anxiety and depression: implementation of the Wellbeing Plus Course in routine clinical care and comparison with research trial outcomes
Authors: Staples Lauren G. , Fogliati Vincent J. , Dear Blake F. , Nielssen Olav , Titov Nickolai
Published: September 2016

Background

The Wellbeing Plus Course is an internet-delivered psychological intervention for older adults with anxiety or depression.

Aims

To compare the effectiveness of the Wellbeing Plus Course in a public health setting (clinic group) with its efficacy in a randomised controlled trial (research group).

Method

Participants (n = 949) were Australian adults aged 60 and above. Primary outcome measures were the Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder scale (GAD-7).

Results

Initial symptom severity was higher in the clinic group and course completion was lower. Both groups showed significant symptom reductions at post-treatment and were satisfied with the treatment. Results were maintained at 3-month follow-up. Within-group symptom changes were comparable between settings; there were no between-group differences on primary outcomes or satisfaction.

Conclusions

The Wellbeing Plus Course is as effective and acceptable in routine clinical care, as it is in controlled research trials.
Neuraxial Anesthesia Reduces Lymphatic Flow: Proof-of-Concept in First In-Human Study

Published: September 2016

Dilation of lymphatic vessels may contribute to iatrogenic dissemination of cancer cells during surgery. We sought to determine whether neuraxial anesthesia reduces regional lymphatic flow. Using nuclear lymphoscintigraphy, 5 participants receiving spinal anesthesia for brachytherapy had lower extremity lymph flow at rest compared with flow under conditions of spinal anesthesia. Six limbs were analyzed. Four limbs were excluded because of failure to demonstrate lymph flow (1 patient, 2 limbs), colloid injection error (1 limb), and undiagnosed deep vein thrombosis (1 limb). All analyzed limbs showed reduced lymph flow washout from the pedal injection site (range 62%–100%) due to neuraxial anesthesia. Lymph flow was abolished in 3 limbs. We report proof-of-concept that neuraxial anesthesia reduces lymphatic flow through a likely mechanism of sympathectomy.
Members of the Rusc protein family interact with Sufu and inhibit vertebrate Hedgehog signaling
Authors: Jin Zhigang , Schwend Tyler , Fu Jia , Bao Zehua , Liang Jing , Zhao Huimin , Mei Wenyan , Yang Jing
Published: September 2016

Hedgehog (Hh) signaling is fundamentally important for development and adult tissue homeostasis. It is well established that in vertebrates Sufu directly binds and inhibits Gli proteins, the downstream mediators of Hh signaling. However, it is unclear how the inhibitory function of Sufu towards Gli is regulated. Here we report that the Rusc family of proteins, the biological functions of which are poorly understood, form a heterotrimeric complex with Sufu and Gli. Upon Hh signaling, Rusc is displaced from this complex, followed by dissociation of Gli from Sufu. In mammalian fibroblast cells, knockdown of Rusc2 potentiates Hh signaling by accelerating signaling-induced dissociation of the Sufu-Gli protein complexes. In Xenopus embryos, knockdown of Rusc1 or overexpression of a dominant-negative Rusc enhances Hh signaling during eye development, leading to severe eye defects. Our study thus uncovers a novel regulatory mechanism controlling the response of cells to Hh signaling in vertebrates.
Tril targets Smad7 for degradation to allow hematopoietic specification in Xenopus embryos
Authors: Green Yangsook Song , Kwon Sunjong , Mimoto Mizuho S. , Xie Yuanyuan , Christian Jan L.
Published: September 2016

In Xenopus laevis, bone morphogenetic proteins (Bmps) induce expression of the transcription factor Gata2 during gastrulation, and Gata2 is required in both ectodermal and mesodermal cells to enable mesoderm to commit to a hematopoietic fate. Here, we identify tril as a Gata2 target gene that is required in both ectoderm and mesoderm for primitive hematopoiesis to occur. Tril is a transmembrane protein that functions as a co-receptor for Toll-like receptors to mediate innate immune responses in the adult brain, but developmental roles for this molecule have not been identified. We show that Tril function is required both upstream and downstream of Bmp receptor-mediated Smad1 phosphorylation for induction of Bmp target genes. Mechanistically, Tril triggers degradation of the Bmp inhibitor Smad7. Tril-dependent downregulation of Smad7 relieves repression of endogenous Bmp signaling during gastrulation and this enables mesodermal progenitors to commit to a blood fate. Thus, Tril is a novel component of a Bmp-Gata2 positive-feedback loop that plays an essential role in hematopoietic specification.
Accuracy of mandibular force profiles for bite force estimation and feeding behavior reconstruction in extant and extinct carnivorans
Authors: Therrien François , Quinney Annie , Tanaka Kohei , Zelenitsky Darla K.
Published: September 2016

Mandibular force profiles apply the principles of beam theory to identify mandibular biomechanical properties that reflect the bite force and feeding strategies of extant and extinct predators. While this method uses external dimensions of the mandibular corpus to determine its biomechanical properties, more accurate results could potentially be obtained by quantifying its internal cortical bone distribution. To test this possibility, mandibular force profiles were calculated using both external mandibular dimensions (‘solid mandible model’) and quantification of internal bone distribution of the mandibular corpus obtained from CT scans (‘hollow mandible model’) for five carnivorans (Canis lupus, Crocuta crocuta, Panthera leo, Neofelis nebulosa, and the extinct Canis dirus). Comparison reveals that the solid model slightly overestimates mandibular biomechanical properties, but the pattern of change in biomechanical properties along the mandible remains the same. As such, feeding behavior reconstructions are consistent between the two models and are not improved by computed tomography. Bite force estimates produced by the two models are similar, except for Crocuta where the solid model underestimates bite force by 10%-14%. This discrepancy is due to the more solid nature of the Crocuta mandible relative to other carnivorans. Therefore, computed tomography improves bite force estimation accuracy for taxa with thicker mandibular corpora, but not significantly so otherwise. Bite force estimates derived from mandibular force profiles are far closer to empirically-measured bite force than those inferred from jaw musculature dimension. Consequently, bite force estimates derived from this method can be used to calibrate finite-element analysis models.
The parasitic wasp Cotesia congregata uses multiple mechanisms to control host (Manduca sexta) behaviour
Authors: Adamo Shelley Anne , Kovalko Ilya , Turnbull Kurtis F. , Easy Russell H. , Miles Carol I.
Published: September 2016

Some parasites alter the behaviour of their hosts. The larvae of the parasitic wasp Cotesia congregata develop within the body of the caterpillar Manduca sexta. During the initial phase of wasp development, the host's behaviour remains unchanged. However, once the wasps begin to scrape their way out of the caterpillar, the caterpillar host stops feeding and moving spontaneously. We found that the caterpillar also temporarily lost sensation around the exit hole created by each emerging wasp. However, the caterpillars regained responsiveness to nociception in those areas within 1 day. The temporary reduction in skin sensitivity is probably important for wasp survival because it prevents the caterpillar from attacking the emerging wasp larvae with a defensive strike. We also found that expression of plasmatocyte spreading peptide (PSP) and spätzle genes increased in the fat body of the host during wasp emergence. This result supports the hypothesis that the exiting wasps induce a cytokine storm in their host. Injections of PSP suppressed feeding, suggesting that an augmented immune response may play a role in the suppression of host feeding. Injection of wasp larvae culture media into non-parasitized caterpillars reduced feeding, suggesting that substances secreted by the wasp larvae may help alter host behaviour.
Molecular and Crystal Structures of Dicationic Tetrakis(1,3-benzodithiol-2-ylidene)cyclopentanone

Published: September 2016

Molecular and crystal structures of dicationic tetrakis(1,3-benzodithiol-2-ylidene)cyclopentanone (1b), (1b2+)2(ReO4−)4(CH3CN)3(H2O)0.7, were successfully determined by X-ray single-crystal diffraction. It was suggested that two 1,3-dithiol-2-ylidenes adjacent to the carbonyl group were effectively conjugated with each other. The remaining two 1,3-dithiol-2-ylidenes, where two positive charges were mainly distributed, were considerably twisted from the central five-membered ring.

Multi-site tumor sampling (MSTS) improves the performance of histological detection of intratumor heterogeneity in clear cell renal cell carcinoma (CCRCC)
Authors: Guarch Rosa , Cortés Jesús M. , Lawrie Charles H. , López José I.
Published: September 2016

Current standard-of-care tumor sampling protocols for CCRCC (and other cancers) are not efficient at detecting intratumoural heterogeneity (ITH). We have demonstrated in silico that an alternative protocol, multi-site tumor sampling (MSTS) based upon the divide and conquer (DAC) algorithm, can significantly increase the efficiency of ITH detection without extra costs. Now we test this protocol on routine hematoxylin-eosin (HE) sections in a series of 38 CCRCC cases. MSTS was found to outperform traditional sampling when detecting either high grade (p=0.0136) or granular/eosinophilic cells (p=0.0114). We therefore propose that MSTS should be used in routine clinical practice.
Turbulent Stability of Emergent Roles: The Dualistic Nature of Self-Organizing Knowledge Coproduction
Authors: Arazy Ofer , Daxenberger Johannes , Lifshitz-Assaf Hila , Nov Oded , Gurevych Iryna
Published: September 2016

Increasingly, new forms of organizing for knowledge production are built around self-organizing coproduction community models with ambiguous role definitions. Current theories struggle to explain how high-quality knowledge is developed in these settings and how participants self-organize in the absence of role definitions, traditional organizational controls, or formal coordination mechanisms. In this article, we engage the puzzle by investigating the temporal dynamics underlying emergent roles on individual and organizational levels. Comprised of a multilevel large-scale empirical study of Wikipedia stretching over a decade, our study investigates emergent roles in terms of prototypical activity patterns that organically emerge from individuals’ knowledge production actions. Employing a stratified sample of 1,000 Wikipedia articles, we tracked 200,000 distinct participants and 700,000 coproduction activities, and recorded each activity’s type. We found that participants’ role-taking behavior is turbulent across roles, with substantial flow in and out of coproduction work. Our findings at the organizational level, however, show that work is organized around a highly stable set of emergent roles, despite the absence of traditional stabilizing mechanisms such as predefined work procedures or role expectations. This dualism in emergent work is conceptualized as “turbulent stability.” We attribute the stabilizing factor to the artifact-centric production process and present evidence to illustrate the mutual adjustment of role taking according to the artifact’s needs and stage. We discuss the importance of the affordances of Wikipedia in enabling such tacit coordination. This study advances our theoretical understanding of the nature of emergent roles and self-organizing knowledge coproduction. We discuss the implications for custodians of online communities as well as for managers of firms engaging in self-organized knowledge collaboration.
Spillover Effects in Seeded Word-of-Mouth Marketing Campaigns
Authors: Chae Inyoung , Stephen Andrew T. , Bart Yakov , Yao Dai
Published: September 2016

Seeded marketing campaigns (SMCs) involve firms sending products to selected customers and encouraging them to spread word of mouth (WOM). Prior research has examined certain aspects of this increasingly popular form of marketing communication, such as seeding strategies and their efficacy. Building on prior research, this study investigates the effects of SMCs that extend beyond the generation of WOM for a campaign’s focal product by considering how seeding can affect WOM spillover effects at the brand and category levels. The authors introduce a framework of SMC-related spillover effects, and empirically estimate these with a unique data set covering 390 SMCs for products from 192 different cosmetics brands. Multiple spillover effects are found, suggesting that while SMCs can be used primarily to stimulate WOM for a focal product, marketers must also account for brand- and category-level WOM spillover effects. Specifically, seeding increases conversations about that product among nonseed consumers, and, interestingly, decreases WOM about other products from the same brand and about competitors’ products in the same category as the focal product. These findings indicate that marketers can use SMCs to focus online WOM on a particular product by drawing consumers away from talking about other related, but off-topic, products.

Published: September 2016

Chronic kidney disease (CKD) is becoming a worldwide problem. However, current treatment options are limited. In the current study we showed that QiShenYiQi (QSYQ), a water-ethanol extract from several Chinese medicines, is a potent inhibitor of renal interstitial fibrosis. QSYQ inhibited transforming growth factor-β1 (TGF-β1)-responsive α-smooth muscle actin (α-SMA), collagen I, and fibronectin up-regulation in obstructive nephropathy and cultured cells. Administration of QSYQ also inhibited the established renal interstitial fibrosis in obstructive nephropathy. Interestingly, QSYQ selectively inhibited TGF-β1-induced β-catenin up-regulation and downstream gene transcription. Taken together, our study suggests that QSYQ selectively inhibits TGF-β1-induced β-catenin up-regulation and might have significant therapeutic potential for the treatment of renal fibrosis.
A Prematuridade na Perspectiva das mães: Estado Psicoemocional, Autoestima e Bonding em mães Primíparas e Multíparas
Authors: Alexandre Joana Dias , Monteiro Ligia , Branco Irina , Franco Carla
Published: September 2016

A literatura tem referido que a prematuridade do bebé gera nas mães níveis mais elevados de ansiedade, sentimentos depressivos, assim como, níveis mais baixos de autoestima, comparativamente com mães de bebés de termo, o que poderá conduzir a um envolvimento emocional mais negativo com o recém-nascido. Essa vivência parece variar em função da paridade das mães (i.e., mãe pela primeira vez vs. multípara) não obstante não serem muito claras as particularidades desta variável. Este​ estudo teve como objetivo analisar num grupo de mães primíparas e multíparas com bebés prematuros, as associações entre o estado Psicoemocional, a Autoestima e o Bonding maternos. Participaram 50 mães (27 primíparas e 23 multíparas), com bebés pré-termo recrutados numa maternidade pública de Lisboa. Os resultados indicam que as mães multíparas apresentam níveis mais elevados de Sentimentos Depressivos expressando, também, uma maior Capacidade e Preparação Geral para a função materna. A Capacidade Geral para tratar do bebé surge associada de forma negativa com o seu estado Psicoemocional e de forma positiva com o Bonding. As associações negativas encontradas entre Ansiedade e Aceitação do bebé, e entre Estado Psicoemocional e Bonding não parecem variar em função da paridade, mostrando que os desafios se colocam a ambos os grupos de mães.
Avaliação de um programa de promoção de habilidades sociais para idosos
Authors: Carneiro Rachel Shimba , Falcone Eliane Falcone
Published: September 2016

Evidências na literatura apontam a importância da qualidade nos relacionamentos sociais, mas não fornecem dados suficientes que indiquem como auxiliar os idosos a se tornarem socialmente competentes. O presente estudo pretende avaliar a eficácia de um Programa de Promoção de Habilidades Sociais para Idosos (PHSI). A pesquisa contou com a participação de 40 idosos. As habilidades sociais foram avaliadas antes e depois da intervenção por meio de uma medida de autorrelato e o desempenho através de jogos de papéis em sete situações sociais. Os resultados apontaram melhora significativa no desempenho social dos participantes do grupo experimental, em relação ao grupo controle, nos contextos envolvendo conflito de interesses. Análises intragrupos também confirmaram uma melhora na capacidade de lidar com situações interpessoais que demandam a afirmação e defesa de direitos. Esses resultados constatam que o Programa criado promoveu habilidades assertivas, previamente apontadas na literatura como deficitárias na população de idosos.
Grooming Online em Portugal: um estudo exploratório
Authors: Casa Branca Cláudia Miura , Grangeia Helena , Cruz Olga
Published: September 2016

O grooming online – aliciamento de crianças e jovens através da internet – tem sido alvo de preocupação e estudos a nível internacional. No entanto, o contexto português caracteriza-se pelo relativo desconhecimento sobre o fenómeno. O presente estudo tem como objetivos conhecer as experiências, perceções e inseguranças dos/as jovens acerca do grooming online, bem como revelar números de vitimação. Pretende-se, ainda, analisar as diferenças de género e etárias, quer ao nível da vitimação quer ao nível da perceção da gravidade do grooming online e do sentimento de insegurança relativamente ao fenómeno. Optou-se por um estudo exploratório de natureza quantitativa e os dados foram recolhidos através de um questionário construído para o efeito. A amostra foi constituída por 151 participantes, 76 (50,3%) do sexo masculino e 75 (49,7%) do sexo feminino. Os resultados encontrados neste estudo, nomeadamente uma percentagem de 20,5% de vitimação por grooming online, revelam uma realidade preocupante em Portugal, pelo que este fenómeno deve ser alvo de maior atenção e discussão no nosso país, inclusive através de modificações legislativas para que se possa atuar sobre o mesmo.
Rejecting Responsibility: Low Physical Involvement in Obtaining Food Promotes Unhealthy Eating
Authors: Hagen Linda , Krishna Aradhna , McFerran Brent
Published: September 2016

Five experiments show that less physical involvement in obtaining food leads to less healthy food choices. The authors find that when participants are given the choice of whether to consume snacks that they perceive as relatively unhealthy, they have a greater inclination to consume them when less (vs. more) physical involvement is required to help themselves to the food; this is not the case for snacks that they perceive as relatively healthy. Further, when participants are given the opportunity to choose their portion size, they select larger portions of unhealthy foods when less (vs. more) physical involvement is required to help themselves to the food; again, this is not the case for healthy foods. The authors suggest that this behavior occurs because being less physically involved in serving one's food allows participants to reject responsibility for unhealthy eating and thus to feel better about themselves after indulgent consumption. These findings add to the research on consumers’ self-serving attributions and to the growing literature on factors that nudge consumers toward healthier eating decisions.
Performance analysis of variable speed multiphase induction motor with pole phase modulation
Authors: Liu Huijuan , Wang Jun , Zhang Zhenyang
Published: September 2016

The pole phase modulation (PPM) technique is an effective method to extend speed range and torque capabilities for an integrated starter and hybrid electric vehicles applications. In this paper, the five pole-phase combination types of a multiphase induction motor (IM) with 36 stator slots and 36 stator conductors are presented and compared quantitatively by using the time-stepping finite element method (TS-FEM). The 36 stator conductors of the proposed multiphase IM are fed by a 36 leg inverter and the current phase angle and amplitude of each stator conductor can be controlled independently. This paper focuses on the winding connection, the PPM technique and the performance comparative analysis of each pole-phase combination types of the proposed multiphase IM. The flux distribution, air-gap flux density, output torque, core losses and efficiency of five pole-phase combination types have been investigated.
Modeling and simulation of novel stepped DC coupled quasi Z-Multilevel Inverter for single phase systems
Authors: Meenakshi T. , Vanitha N. Suthanthira
Published: September 2016

This paper presents the modeling and simulation of a novel topology of quasi Z-Multilevel Inverter with stepped DC input. The proposed inverter incorporates a simple switching technique with reduced component count and is aimed at producing boosted multilevel output AC voltage. The inverter consists of two stages and the buck /boost operation is obtained by varying the shoot through period of the pulses obtained by maximum constant boost control with third harmonic injection. With all the advantages of the quasi Z-network, the proposed inverter eliminates the fly back diodes and capacitors present in a conventional Z-Multilevel Inverter. Further the stress on the devices is less which leads to reduction in component value and hence the cost. The novel stepped DC coupled Single Phase quasi Z-Multilevel Inverter is modeled and simulated in the MATLAB - SIMULINK environment and its performance is analyzed for varying input and switching conditions. The voltage and current waveforms across each stage of the inverter is analyzed and the results are presented for different levels of input.
Energy storage systems: power grid and energy market use cases
Authors: Komarnicki Przemysław
Published: September 2016

Current power grid and market development, characterized by large growth of distributed energy sources in recent years, especially in Europa, are according energy storage systems an increasingly larger field of implementation. Existing storage technologies, e.g. pumped-storage power plants, have to be upgraded and extended by new but not yet commercially viable technologies (e.g. batteries or adiabatic compressed air energy storage) that meet expected demands. Optimal sizing of storage systems and technically and economically optimal operating strategies are the major challenges to the integration of such systems in the future smart grid. This paper surveys firstly the literature on the latest niche applications. Then, potential new use case and operating scenarios for energy storage systems in smart grids, which have been field tested, are presented and discussed and subsequently assessed technically and economically.
