Small Step Frequency Changes Due to Footwear Condition Have No Effect on Running Economy
Authors: Warne Joe , Moran Kieran , Warrington Giles 
Published: May 2018

AbstractThe aim of this study is to examine if small increases to step frequency associated with minimal footwear can influence Running Economy (RE). Twelve club-level runners with eight weeks of minimal footwear experience were recruited (age, 41±9 years; stature, 177.2±10.4 cm; body mass, 72.6±10.2 kg; V˙O2max, 52.1±7.5 mL·min−1·kg−1). Two 6-min RE tests, one in minimal footwear and one in conventional running shoes were performed at 11 km·h−1. Two more 6-min tests were completed during which step frequency was controlled using a metronome at the cadence of the opposite footwear condition (RErevSF). Comparisons were completed between the same footwear using repeated measures ANCOVA. The increase in step frequency for minimal footwear vs. conventional running shoes was 7.3±2.3 steps per minute (3.9% difference; 95% CI of difference [5.87 to 8.80 steps/min]; p≤0.001; Cohen’s d=0.70). No significant differences were identified between RE and RErevSF for minimal footwear (40.72±4.08 vs. 41.09±4.19 mL·min−1·kg−1; 95% CI of difference [–1.71 to 0.97]; p=0.55; Cohen’s d=0.09), or conventional running shoes (42.04±4.68 vs. 41.74±5.09 mL·min−1·kg−1; 95% CI of difference [–0.78 to 1.37]; p=0.55; Cohen’s d=0.06). Small changes in step frequency (~4%) did not have any significant impact on RE.

This account describes our group’s latest research in the field of diversity-oriented synthesis of natural products via gold-catalyzed cascade reactions. We present two general strategies based on gold-catalyzed cycloisomerization: a gold-catalyzed cascade reaction of 1,7-diynes and a pinacol-terminated gold-catalyzed cascade reaction. We highlight our development of synthetic methods for the construction of biologically active natural products by using these two strategies.1	Introduction2	Gold-Catalyzed Cascade Reactions of 1,7-Diynes2.1	Collective Synthesis of C15 Oxygenated Drimane-Type Sesquiterpenoids2.2	Synthesis of Left-Wing Fragment of Azadirachtin I2.3	Collective Synthesis of Cladiellins3	Pinacol-Terminated Gold-Catalyzed Cascade Reaction3.1	Asymmetric Formal Total Synthesis of (+)-Cortistatins3.2	Total Synthesis of Orientalol F3.3	Asymmetric Total Synthesis of (–)-Farnesiferol C4	Summary and Outlook
Lipoprotein Profile Modifications during Gestation: A Current Approach to Cardiovascular risk surrogate markers and Maternal-fetal Unit Complications
Authors: Santos Ana Paula Caires dos , Couto Ricardo David 
Published: May 2018

AbstractSeveral changes occur in lipid metabolism during gestation due to hormonal and metabolic changes, which are essential to satisfy the nutritional demands of the maternal-fetal unit development. The gestation shows two distinct periods that begin with fat accumulation, mainly in maternal adipose tissue, and the late phase, characterized by accelerated catabolism, with the increase of fatty acids in the circulation that causes hyperlipidemia, especially the one characterized as hypertriglyceridemia. Maternal hyperlipidemia may be associated with the development of maternal-fetal complications (preterm birth, preeclampsia, vascular complications) and the development of long-term cardiovascular disease. The cardiovascular risk may not only be related to lipoproteins cholesterol content, but also to the number and functionality of circulating lipoprotein particles. This review reports the major changes that occur in lipoprotein metabolism during pregnancy and that are associated with the development of dyslipidemias, lipoprotein atherogenic phenotype, and maternal-fetal unit complications.
Symptom Similarity versus Disease Similarity: Revisiting the Application of the Law of Similars and Challenging the Symptom-Centric Approach in Homeopathy
Authors: Shah Rajesh 
Published: May 2018

AbstractThe system of homeopathic medicine is based on the Law of Similars. It is often implied by students and practitioners of homeopathy that the fundamental principle suggests that if the substance is capable of producing certain ‘symptoms’, it can also remove, treat, or ‘annihilate’ similar symptoms if the same substance is administered in a small dose. Hahnemann clearly highlights the importance of pathogenesis or ‘disease-producing power’, and not just the symptoms-producing power, as a part of the ‘totality of the disease’. The author perceives the need for a rectification in the symptom-centric approach in homeopathy. The pathogenesis of disease includes the mechanisms and the cause, which are more complete than the consideration of mere symptoms. Thus, the fundamental approach needs to be extended beyond the symptoms' similarity to the disease-pathogenesis similarity. Several clinical examples are given based on the imaginary expansion that is constructed on the ‘mind’ symptoms without the inclusion of the pathogenesis of the medicinal substance, suggesting the limitations and the risks to homeopathy of a purely symptom-centric approach.

Authors: Pais Ana Sofia , Areia Ana Luísa Fialho Amaral de , Franco Sofia Margarida Perienes , Fonseca Etelvina Morais Ferreira , Moura José Paulo Achando Silva 
Published: May 2018

AbstractMirror syndrome is an unusual pathological condition in which maternal edema in pregnancy is seen in association with severe fetal and/or placental hydrops. The disease can be life-threatening for both the mother and the fetus. The pathogenesis is poorly understood, and may be confused with preeclampsia, even though distinguishing features can be identified. We report a rare case of mirror syndrome with maternal pulmonary edema associated with fetal hydrops due to Patau syndrome.
Gestational Trophoblastic Neoplasia after Ectopic Molar Pregnancy: Clinical, Diagnostic, and Therapeutic Aspects

Published: May 2018

AbstractThis report presents the case of a patient with gestational trophoblastic neoplasia after a partial hydatidiform mole formed in the Fallopian tube. Ectopic molar pregnancy is a rare condition, with an estimated incidence of 1 in every 20,000 to 100,000 pregnancies; less than 300 cases of it have been reported in the Western literature. The present report is important because it presents current diagnostic criteria for this rare condition, which has been incorrectly diagnosed in the past, not only morphologically but also immunohistochemically. It also draws the attention of obstetricians to the occurrence of ectopic molar pregnancy, which tends to progress to Fallopian tube rupture more often than in cases of ectopic non-molar pregnancy. Progression to gestational trophoblastic neoplasia ensures that patients with ectopic molar pregnancy must undergo postmolar monitoring, which must be just as thorough as that of patients with intrauterine hydatidiform moles, even if chemotherapy results in high cure rates.
Strength design of Zr(x)Ti(x)Hf(x)Nb(x)Mo(x) alloys based on empirical electron theory of solids and molecules

Published: May 2018

Abstract
In this paper, the valence electron structure parameters of Zr(x)Ti(x)Hf(x)Nb(x)Mo(x) alloys were calculated based on the empirical electron theory of solids and molecules (EET), and their performance through these parameters were predicted. Subsequently, the alloys with special valence electron structure parameters were prepared byarc melting. The hardness and high-temperature mechanical properties were analyzed to verify the prediction. Research shows that the influence of shared electron number nA
on the strongest bond determines the strength of these alloys and the experiments are consistent with the theoretical prediction.

Published: May 2018

Abstract

Background
Fear of cancer recurrence (FCR) is a top ongoing concern of breast cancer (BC) survivors and thus the focus of recent intervention development. The Self-Regulation Model of FCR (Lee-Jones C, Humphris G, Dixon R, Hatcher MB. Fear of cancer recurrence–a literature review and proposed cognitive formulation to explain exacerbation of recurrence fears. Psychooncology. 1997;6:95–105.) states that everyday cancer-related events trigger FCR, which, in turn, leads to specific behavioral responses, including checking the body for signs or symptoms of cancer. Links between triggering events, FCR, and checking behavior have not yet been studied in the context of daily life or at the within-person level.

Purpose
The goal of this study was to examine whether FCR has a within-person link with daily checking behavior and whether FCR mediates the link between triggering events and checking behavior.

Methods
Seventy-two early-stage BC survivors completed daily diaries over a 21-day period approximately 5 months after BC surgery. FCR, checking behavior, and triggering events were assessed each evening.

Results
Multilevel modeling results indicated that FCR predicted greater odds of same-day, but not next-day, checking behavior. We found that daily FCR significantly mediated the same-day effect of triggering events on checking behavior. These average within-person effects varied substantially between patients and were not explained by momentary negative affect.

Conclusions
Findings support the within-person relationship between triggering events, FCR, and checking behavior posited by guiding theory, and can inform FCR intervention development.

Abstract
Arterial hypertension (HT) is one of the most frequently recorded comorbidities among patients under antiangiogenic therapy. Inhibitors of vascular endothelial growth factor and vascular endothelial growth factor receptors are most commonly involved in new onset or exacerbation of pre-existing controlled HT. From the pathophysiology point of view, data support that reduced nitric oxide release and sodium and fluid retention, microvascular rarefaction, elevated vasoconstrictor levels, and globular injury might contribute to HT. The purpose of this review was to present recent evidence regarding the incidence of HT induced by antiangiogenic agents, to analyze the pathophysiological mechanisms, and to summarize current recommendations for the management of elevated blood pressure in this field.
Qualitative Research in the Chinese Social Work Academy: Optimism and Invisible Disadvantages
Authors: Xu Yanfeng , Shdaimah Corey , Zhao Fang , Gioia Deborah 
Published: May 2018

Abstract
There has been much discussion about the contributions of qualitative research to social work knowledge, but the experiences of social work faculty engaged in qualitative research are rarely discussed. Social work is at the early developmental stage in China, which makes the country a useful laboratory to examine this question. The current study aimed to understand experiences of Chinese qualitative social work faculty and how their methodological orientation affected their career trajectories. Nine semi-structured, in-depth interviews were conducted and analysed. Thematic data analysis revealed three major themes: suitability, methodological challenges and structural barriers. Findings indicate that qualitative social work research has an optimistic future in China, but methodological challenges and structural barriers create invisible disadvantages. This study highlights the need for rigorous qualitative research training, including apprenticeship; translation of more qualitative learning materials into Chinese; and support for the purchase, training and use of qualitative software packages. The results also point to the need for institutional review boards or other ethical oversight mechanisms. More importantly, there must be greater consensus regarding what constitutes scientific rigour, which projects should be funded, what are evaluative criteria for publication, and whom to hire and promote.
Trading for peace*
Authors: Jha Saumitra 
Published: May 2018

AbstractI examine the conditions under which trade can support peaceful coexistence and prosperity when particular social and ethnic groups are cheap targets of violence. A simple theoretical framework reveals that for a broad set of cases, while inter-group competition generates incentives for violence, the presence of non-replicable, non-expropriable inter-group complementarities becomes necessary to sustain peaceful coexistence over long time horizons. In addition to complementarity, two further conditions are important for deterring violence over time. When relatively mobile groups (e.g. immigrants) are vulnerable, a credible threat to leave can deter violence. When less mobile (indigenous) groups are vulnerable, high-monitoring costs that allow them to withhold production can improve their gains from trade. I describe the implications for indigenous entrepreneurship and cultural assimilation, the development of local institutions supporting inter-ethnic trust and immigration policies and policies aimed at mitigating conflict through financial innovations. I illustrate these implications using contemporary evidence and historical cases of organizations and institutions created to engender trade and support peace drawn from Africa, Asia, Europe and Latin America.
Unpacking policy formulation and industry influence: the case of the draft control of marketing of alcoholic beverages bill in South Africa
Authors: Bertscher Adam , London Leslie , Orgill Marsha 
Published: May 2018

Abstract
Alcohol is a major contributor to the Non-Communicable Disease burden in South Africa. In 2000, 7.1% of all deaths and 7% of total disability-adjusted life years were ascribed to alcohol-related harm in the country. Regulations proposed to restrict alcohol advertising in South Africa present an evidence-based upstream intervention. Research on policy formulation in low- and middle-income countries is limited. This study aims to describe and explore the policy formulation process of the 2013 draft Control of Marketing of Alcoholic Beverages Bill in South Africa between March 2011 and May 2017. Recognising the centrality of affected actors in policy-making processes, the study focused on the alcohol industry as a central actor affected by the policy, to understand how they—together with other actors—may influence the policy formulation process. A qualitative case study approach was used, involving a stakeholder mapping, 10 in-depth interviews, and review of approximately 240 documents. A policy formulation conceptual framework was successfully applied as a lens to describe a complex policy formulation process. Key factors shaping policy formulation included: (1) competing and shared values—different stakeholders promote conflicting ideals for policymaking; (2) inter-department jostling—different government departments seek to protect their own functions, hindering policy development; (3) stakeholder consultation in democratic policymaking—policy formulation requires consultations even with those opposed to regulation and (4) battle for evidence—evidence is used strategically by all parties to shape perceptions and leverage positions. This research (1) contributes to building an integrated body of knowledge on policy formulation in low- and middle-income countries; (2) shows that achieving policy coherence across government departments poses a major challenge to achieving effective health policy formulation and (3) shows that networks of actors with commercial and financial interests use diverse strategies to influence policy formulation processes to avoid regulation.
The Limit Point of the Pentagram Map
Authors: Glick Max 
Published: May 2018

Abstract
The pentagram map is a discrete dynamical system defined on the space of polygons in the plane. In the 1st paper on the subject, Schwartz proved that the pentagram map produces from each convex polygon a sequence of successively smaller polygons that converges exponentially to a point. We investigate the limit point itself, giving an explicit description of its Cartesian coordinates as roots of certain degree three polynomials.
Vertical Distribution Relations for Special Cycles on Unitary Shimura Varieties
Authors: Boumasmoud Réda , Brooks Ernest Hunter , Jetchev Dimitar P 
Published: May 2018

Abstract
We consider cycles on three-dimensional Shimura varieties attached to unitary groups, defined over extensions of a complex multiplication (CM) field $E$, which appear in the context of the conjectures of Gan et al. [6]. We establish a vertical distribution relation for these cycles over an anticyclotomic extension of $E$, complementing the horizontal distribution relation of [8], and use this to define a family of norm-compatible cycles over these fields, thus obtaining a universal norm construction similar to the Heegner $\Lambda $-module constructed from Heegner points.
Collections of Hypersurfaces Containing a Curve
Authors: Tseng Dennis 
Published: May 2018

Abstract
We consider the closed locus parameterizing $k$-tuples of hypersurfaces that have positive dimensional intersection and fail to intersect properly, and show in a large range of degrees that its unique irreducible component of maximal dimension consists of tuples of hypersurfaces whose intersection contains a line. We then apply our methods in conjunction with a known reduction to positive characteristic argument to find the unique component of maximal dimension of the locus of hypersurfaces with positive dimensional singular loci. We will also find the components of maximal dimension of the locus of smooth hypersurfaces with a higher dimensional family of lines through a point than expected.
Multidimensional Assessment of Social Desirability Bias: An Application of Multiscale Item Randomized Response Theory to Measure Academic Misconduct
Authors: Wlömert Nils , Pellenwessel David , Fox Jean-Paul , Clement Michel 
Published: May 2018

AbstractIt is challenging for survey researchers to investigate sensitive topics due to concerns about socially desirable responding (SDR). The susceptibility to social desirability bias may vary not only between individuals (e.g., different perceptions about social norms) but also within individuals (e.g., perceived sensitivity of different items). Thus, controlling for SDR is particularly challenging when analyzing multidimensional constructs that are measured via multiple groups of items with varying degrees of sensitivity. In this research, we address this challenge using a combination of a randomized response (RR) approach for data collection and a multiscale item response theory (IRT) model for data analysis. While the RR approach protects the anonymity of respondents at the item level, the multiscale IRT approach accounts for the multidimensional nature of the construct and explicitly models the item-level differences in the measurement of its dimensions. We empirically demonstrate the benefits of the model using a multidimensional self-report instrument for the assessment of academic misconduct of university students. Based on an experiment with random assignment, our results uncover considerable differences in the perceived sensitivity, both between the construct dimensions and between their measurement items. These findings support the view that individuals engage in SDR to varying degrees depending on the perceived sensitivity of the specific items and groups of items. In contrast, a social desirability scale that treats SDR as a stable personality trait is not found to capture meaningful differences in response style. Finally, we show how structural models can be incorporated into the framework to link the latent construct’s dimensions to individual-level explanatory variables.
Research network emergence: Societal issues in nanotechnology and the center for nanotechnology in society
Authors: Youtie Jan , Shapira Philip , Reinsborough Michael , Fisher Erik 
Published: May 2018

Abstract
This article looks at the creation of a network of researchers of social issues in nanotechnology and the role of the Center for Nanotechnology in Society at Arizona State University (CNS-ASU) in the creation of this network. The extent to which CNS-ASU is associated with the development of a research network around the study of social issues in nanotechnology is examined through geographic mapping of co-authors and citations of center publications, network analysis of co-authors of papers on social issues in nanotechnology, and a disciplinary analysis of these papers. The results indicate that there is an extensive network of co-authorships among researchers studying social issues in nanotechnology with CNS-ASU at the center of this network. In addition, papers written by center members and affiliates integrate a diverse range of disciplines. Qualitative data are used to interpret some of the ways that citation occurs.

Abstract

Background
Mass drug administrations (MDAs) are part of the World Health Organization’s Plasmodium falciparum elimination strategy for the Greater Mekong Subregion (GMS). In Cambodia, a 2015–2017 clinical trial evaluated the effectiveness of MDA. This article explores factors that influence the feasibility and acceptability of MDA, including seasonal timing, financial incentives and the delivery model.

Methods
Quantitative data were collected through structured questionnaires from the heads of 163 households. Qualitative data were collected through 25 semi-structured interviews and 5 focus group discussions with villagers and local health staff. Calendars of village activities were created and meteorological and malaria treatment records were collected.

Results
MDA delivered house-to-house or at a central point, with or without compensation, were equally acceptable and did not affect coverage. People who knew about the rationale for the MDA, asymptomatic infections and transmission were more likely to participate. In western Cambodia, MDA delivered house-to-house by volunteers at the end of the dry season may be most practicable but requires the subsequent treatment of in-migrants to prevent reintroduction of infections.

Conclusions
For MDA targeted at individual villages or village clusters it is important to understand local preferences for community mobilisation, delivery and timing, as several models of MDA are feasible.
