Published: October 2018

AbstractPersistent mating‐induced endometritis (PMIE) is a significant cause of mare infertility hence its treatment would advance the management of susceptible mares. Preimplantation factor (PIF) is secreted by viable embryos, including human, mouse and cattle, and is essential for maternal immune‐tolerance without immune‐suppression by modulating inflammation. This preliminary study aimed to test whether PIF exerts inflammatory‐modulating properties upon equine endometrium challenged with Escherichia coli‐derived lipopolysaccharide (LPS) using endometrial explant culture. Follicular (n = 3), luteal (n = 4), anoestrous (n = 4) and transitional (n = 4) stage endometrial explants were established and cultured in triplicate in either serum‐free medium alone (control) or medium with; 50 or 100 nmol/L synthetic PIF (sPIF); 3 μg/mL LPS; LPS and 50 or 100 nmol/L sPIF; or scrambled PIF (PIFscr; same amino acid composition arranged in a different order). Media samples were collected at 24 and 72 h, representing acute and chronic inflammatory response. Radioimmunoassay determined Prostaglandin F2α (PGF2α) as an inflammatory marker. The only significant observation was the abrogation of PGF2α response to LPS challenge by 100 nmol/L PIF for follicular stage tissue, 24 h after treatment. Further studies are therefore, warranted to realise PIF potential in managing PMIE.
Rigorous justification of the asymptotic model describing a curved‐pipe flow in a time‐dependent domain

Published: October 2018

AbstractThis paper is devoted to the mathematical justification of an asymptotic model of a viscous flow in a curved tube with moving walls by proving error estimates. To this aim, we first construct the space correctors near the pipe's inlet and outlet due to the boundary layer phenomenon. In order to guarantee the adequate properties for these correctors we study what we called modified Leray's problem defined in a semi‐infinite strip. We ensure the existence and uniqueness of an exponential decaying solution when the axial variable tends to infinity. Then, by deriving a Poincaré's type inequality and other estimates for the boundary value problems taking into account the condition on the pipe's lateral boundary, we evaluate the difference between the asymptotic approximation and the exact solution of the problem.

AbstractRapid prototyping (RP) or layered manufacturing (LM) technologies have been extensively used to manufacture prototypes composed mainly of plastics, polymers, paper, and wax due to the short product development time and low costs of these technologies. However, such technologies, with the exception of selective laser melting and sintering, are not used to fabricate metallic products because of the resulting poor life, short cycle, poor surface finish, and low structural integrity of the fabricated parts. The properties endowed by these parts do not match those of functional parts. Therefore, extensive research has been conducted to develop new additive manufacturing (AM) technologies by extending existing RP technologies. Several AM technologies have been developed for the fabrication of metallic objects. These technologies utilize materials, such as Ni-, Al-, and Ti-based alloys and stainless steel powders, to fabricate high-quality functional components. The present work reviews the type of materials used in laser-based AM processes for the manufacture of metallic products. The advantages and disadvantages of processes and different materials are summarized, and future research directions are discussed in the final section. This review can help experts select the ideal type of process or technology for the manufacturing of elements composed of a given alloy or material (Ni, Ti, Al, Pb, and stainless steel).
Lessons learned from a&nbsp;student-driven initiative to design and implement an Organ and Tissue Donation course across Canadian medical schools

Published: October 2018

The competencies required of the well-trained physician are constantly evolving, and medical education must adapt accordingly. In response, a growing number of influential medical education licensing and accreditation bodies have proposed frameworks that outline society’s expectations of physician competencies. In Canada, undergraduate and graduate curricula have undergone major changes to meet the specifications of the CanMEDS framework, and similar efforts are underway internationally. Nonetheless, ensuring the values enshrined within such frameworks become integral to a physician’s identity remains challenging. We believe that student-led curricular initiatives represent a novel way of approaching this shifting medical education landscape. In this article, we reflect on lessons we learned as medical students spearheading an initiative to change how organ and tissue donation is taught in Canadian medical schools. Citing relevant medical education literature where applicable, we include a detailed description of our approach as a roadmap for students contemplating their own curricular innovations. By outlining the factors influencing this project’s implementation, as well as the benefits and limitations of student participation in curriculum reform, we offer educators a fresh perspective on optimizing the student role in this important process. Ultimately, the authors argue that not only can student participation render curricular content more accessible to learners, but that the responsibilities students take on in this role naturally lead to the development of CanMEDs-based competencies such as advocacy, scholarship, and inter-professionalism.

Published: October 2018

ABSTRACTIntroductionSuicide is a major public health concern. One consistently cited risk factor for suicide is childhood maltreatment, which also may play a role in the transition from suicidal ideation to suicidal behavior.MethodThe current study aimed to examine the relationship between childhood maltreatment and suicide attempts during adolescence (N = 4834; 52.1% female; 67.5% Caucasian). Data from the U.S. National Longitudinal Study of Adolescent Health were utilized. Forty‐six theoretically‐relevant risk factors were explored as potential mediators of this relationship using an exploratory mediation data analytic method.ResultsResults demonstrated a significant childhood maltreatment ‐ suicide attempt relationship only among females. After considering demographics and suicidal ideation, having received counseling in the previous 12 months was the most influential mediator, followed by having a friend attempt suicide in the previous 12 months.ConclusionsThese findings highlight potential gender differences in the relationship between childhood maltreatment and later suicide attempts, and, moreover, the importance of assessing for recent exposure to peer suicidal behavior in suicide risk assessments.
Rethinking Masculinity in the Neoliberal Order: Cameroonian Footballers, Fijian Rugby Players, and Senegalese Wrestlers

Published: October 2018

AbstractIn the Global South since the 1980s, when economic downturns under pressure from the forces of neoliberalism eroded social relations, sport and athletes’ bodies have become major loci where masculinity is constituted and debated. Sport masculinity now fills a vacuum left by the evacuation of traditional forms of masculinity, which are no longer available to the new generations of men. For them, the possibility of employment in the sport industries in the Global North has had a transformative effect, despite the extremely limited probability of success. During the same period of time, the world of sport has become commoditized, mediatized, and corporatized, transformations that have been spearheaded by the growing importance of privatized media interests. Professional athletes have become neoliberal subjects responsible for their own destiny in an increasingly demanding and unpredictable labor market. In Cameroon, Fiji, and Senegal, athletic hopefuls prospectively embody this new gendered subjectivity by mobilizing locally available instruments that most closely resemble neoliberal subjectivity, such as Pentecostalism and maraboutism. Through the conduit of sport, the masculine self has been transformed into a neoliberal subject in locations where this is least expected. What emerges is a new approach to masculinity that eschews explanations based on the simple recognition of diverse and hierarchically organized masculinities, and instead recognizes masculinity in its different manifestations as embedded, scalar, relational, and temporally situated.
The Aboriginal Alibi: Governing Dispossession in Colonial Bombay
Authors: Chhabria Sheetal 
Published: October 2018

AbstractThis article analyzes representations of the Koli as aboriginal in colonial Bombay, and explores the ends to which various actors have narrated Koli aboriginality. It examines the relationship between the historical deployment of the concept of aboriginality and its mediating role in the power of capital and state-making practices in one colonial urban context. The article shows how the Koli, as Bombay's “aboriginals,” gained concessions that served as an alibi for the market-based dispossession of the remainder of the city's population, and also as a pretext for claim-making by peoples with competing collective identities who used the tale of Koli identity and history as a narrative resource to argue for their own nativity. The Koli case helps us understand the co-emergence of the powers of caste and capital in Bombay, and compels us to revisit important, broader questions about relationships between aboriginal or indigenous peoples, capitalism, colonialism, liberalism, and governance.
Theologies of Auspicious Kingship: The Islamization of Chinggisid Sacral Kingship in the Islamic World
Authors: Brack Jonathan 
Published: October 2018

AbstractThis article explores the fashioning of a new discursive realm of Islamic kingship in thirteenth–fourteenth-century Mongol-ruled Iran (the Ilkhanate). It examines how literati, historians, and theologians ingeniously experimented at the Ilkhanid court with Persian and Islamic concepts and titles to translate and elaborate their Mongol patrons’ claims to govern through a unique affinity with heaven. The fusion of Mongol and Islamic elements formulated a new political vocabulary of auspicious, sacred, cosmic, and messianic rulership that Turco-Mongol Muslim courts, starting in the fifteenth century, extensively appropriated and expanded to construct new models of imperial authority. A comparison with Buddhist and Confucian assimilative approaches to the Mongol heaven-derived kingship points to a reciprocal process. Mongol rulers were not simply poured into preset Muslim and Persian molds; symbols and titles were selectively appropriated and refashioned into potent vessels that could convey a vision of Islamic kingship that addressed Chinggisid expectations. From their desire to collect and assume local religious and political traditions that could support and enhance their own legitimizing claims, the Mongols set in motion a process that led to their own integration into the Perso-Islamic world, and also facilitated the emergence of new political theologies that enabled models of divine kingship to inhabit the Islamic monotheistic world.
Toxocara sero-prevalence and its relationship with allergic asthma in asthmatic patients in north-eastern Iran

Published: October 2018

AbstractToxocariasis is an important neglected tropical disease that has been suggested as a possible etiologic agent of asthma. The objective of the present study was to investigate possible significant association between Toxocara seroprevalence and asthma in a clinic-based case-control study. Blood samples were collected from human subjects aged 5–70 years, 50 of whom had signs of asthma and 50 of whom had no signs of asthma. Risk factors for asthma and Toxocara spp. infection were assessed by a questionnaire given to each patient. Blood samples were analysed to measure levels of anti-Toxocara spp. immunoglobulin G (IgG). Patients with bronchial asthma were observed to have higher Toxocara spp. seropositivity than that of the non-asthmatic controls (6 vs 2%, P = 0.47). The mean anti-Toxocara spp. antibody titre was not significantly higher in patients with bronchial asthma than in individuals without asthma (P = 0.395, 95% CI = 0.579–1.45). There was no significant difference in the mean age, sex, social class, exposure to smoking and presence of domestic dog or cat at home between the two groups (P ≥ 0.05). The presence of anti-Toxocara spp. IgG was statistically associated with higher blood eosinophils, but it was not associated with asthma (P ≥ 0.05). The observed relationship between exposure to Toxocara spp. infection and bronchial asthma in Iranian patients warrants further evaluation. An understanding of any potential influence on the pathogenesis of human asthma provides a potential avenue for prevention.
New Punitiveness on the Move: How the US Prison Model and Penal Policy Arrived in Colombia
Authors: DE DARDEL JULIE , SÖDERSTRÖM OLA 
Published: October 2018

AbstractWithin the neocolonial context of ‘Plan Colombia’ in the early 2000s, agents of the US Federal Bureau of Prisons (BOP) took up position in the heart of the Colombian penitentiary administration to lead a reform based on the United States’ ultra-punitive penal regime. This paper analyses how the reform was set up on the ground, shedding light on the partially divergent expectations of the two governments. Drawing on recent literature on the mobility of policies and built forms, the paper argues that the introduction of US-inspired prisons in Colombia is a striking case where a mobile policy and a travelling architectural type coincided and complemented each other.
Stability and dynamics of a cosh-Gaussian laser beam in relativistic thermal quantum plasma
Authors: Mahajan Ranju , Richa  , Gill Tarsem Singh , Kaur Ravinder , Aggarwal Munish 
Published: October 2018

AbstractThis paper presents an investigation on the self-focusing of a cosh-Gaussian laser beam in the thermal quantum plasma (TQP) by taking into account the effects of relativistic nonlinearity. An appropriate nonlinear Schrödinger equation has been solved analytically by applying the variational approach. The self-focusing and the self-phase modulation are examined under a variety of parameters. The self-trapping of a cosh-Gaussian laser beam is further studied at various values of the decentered parameter, b with different absorption levels, ${k}^{\prime}_i$. Numerical analysis shows that these parameters play a vital role in propagation characteristics. The significant contribution of the quantum effects to enhance the self-focusing and minimize the longitudinal phase has been observed. Further, a comparison has been made with the classical relativistic (CR), the relativistic cold quantum (RCQ), and the thermal quantum (TQ) regimes. The self-focusing is found to occur earlier and is strongest for the case of TQP in the present analysis.
Leveraging human knowledge in tabular reinforcement learning: a study of human subjects
Authors: Rosenfeld Ariel , Cohen Moshe , Taylor Matthew E. , Kraus Sarit 
Published: October 2018

AbstractReinforcement learning (RL) can be extremely effective in solving complex, real-world problems. However, injecting human knowledge into an RL agent may require extensive effort and expertise on the human designer’s part. To date, human factors are generally not considered in the development and evaluation of possible RL approaches. In this article, we set out to investigate how different methods for injecting human knowledge are applied, in practice, by human designers of varying levels of knowledge and skill. We perform the first empirical evaluation of several methods, including a newly proposed method named State Action Similarity Solutions (SASS) which is based on the notion of similarities in the agent’s state–action space. Through this human study, consisting of 51 human participants, we shed new light on the human factors that play a key role in RL. We find that the classical reward shaping technique seems to be the most natural method for most designers, both expert and non-expert, to speed up RL. However, we further find that our proposed method SASS can be effectively and efficiently combined with reward shaping, and provides a beneficial alternative to using only a single-speedup method with minimal human designer effort overhead.
Onobrychis viciifolia; a comprehensive literature review of its history, etymology, taxonomy, genetics, agronomy and botany
Authors: Mora-Ortiz M. , Smith L. M. J. 
Published: October 2018

AbstractOnobrychis viciifolia (sainfoin) is a forage legume crop with many positive agronomic, environmental, nutritional and nutraceutical attributes. Farmers also benefit from its drought tolerance in areas of low rainfall and light free draining soil, mainly due to its deep taproot. It is resistant to most common pest and diseases and is a valuable resource for pollinators, specifically cultivated for honey production in some regions. It has many benefits for animals, being highly palatable and without danger of bloat, which can be life-threatening to livestock. Its decline in Northern Europe started during the Green Revolution and was impacted by changes towards more intensive farming. Unlike other forage legume crops such as red clover and lucerne, sainfoin does not respond well to inputs and is difficult to establish and maintain. Sainfoin could be classified as an ‘orphan crop’ with very little genetic improvement or agronomic studies in the past 60 years. In the past 5–10 years, however, there has been a resurgence in interest and this has given rise to a number of studies and initiation of systematic improvement of the crop, which is indispensable to its reintroduction into the farmed environment. Interest has been driven in part by considerable evidence to suggest that condensed tannins present in the legume foliage, together with other polyphenol compounds, have positive effects on animal nutrition together with anthelmintic properties. These compounds are also thought to play a role in environmental benefits. There remain many challenges to address in order to optimize the potential for cultivation of sainfoin and its use as a beneficial forage crop. This review makes particular reference to a recently completed project; ‘Legume Plus’, funded by the European Union and embracing a multi-disciplinary approach to both understand and improve the crop for farmers. The present review covers results from both this project and other studies during the past 5 years, also drawing on historic studies of etymology, taxonomy, genetics, agronomy and botany, aiming to be a useful resource for research and for practical plant breeders and agronomists.

Abstract. Background: Curcumin is found in the rhizomes of the turmeric plant that has been showed antioxidant and anti-inflammatory effect. The aim of this study was to evaluate the effects of systemic curcumin therapy on alveolar bone loss in an experimental periodontitis model in rats. Material and Methods: Thirty-two male Wistar rats were randomly divided to 4 groups: 75 mg/kg/daily curcumin (C75; n =8), 150 mg/kg/daily curcumin (C150; n =8), Control (n =8), and Ligated (n =8). Curcumin was administrated using gastric gavage. After 12 days, the rats were sacrificed. Right mandibles samples were histopathologically examined. Alveolar bone loss was measured. Interleukin 1β (IL-1β) and interleukin 10 (IL-10) were evaluated in the serum samples and gingival homogenates. Results: The measurements of alveolar bone loss in the mandibular molars revealed significantly higher bone-loss values in the Ligated group than the Control, C75 and C150 groups. The IL-1β levels in the gingival homogenates were significantly increased in the Ligated group compared to those of the Control, C75 and C150 groups. The serum IL-1β levels in the Ligated group were significantly higher than the Control group. The mean osteoblast numbers in the Ligated group were lower than those of the Control, C75 and C150 groups. The C150 groups showed significantly more osteoblasts than the Control group. The osteoclast numbers in the Ligated group increased significantly compared to the C75, C150 and control groups. Conclusion: This study demonstrates that systemic administration of curcumin at the 75 and 150mg/kg doses reduced alveolar bone loss in the periodontal disease in rats.Keywords: Alveolar bone loss, Antioxidant, Curcumin, Ligature-induced, Histomorphometric, Micronutrition
Depression as a Predictor of Facebook Surveillance and	Envy
Authors: Scherr Sebastian , Toma Catalina L. , Schuster Barbara 
Published: October 2018

Abstract. Prior research has shown an association between Facebook users’ likelihood of engaging in social surveillance (i.e., browsing through friends’ postings without directly interacting with them), their experience of envy, and their depressive symptoms. Yet the directionality and duration of this effect are unclear. Drawing on the stress generation hypothesis, we postulate that depression increases Facebook surveillance and envy, which may increase depression over time. Using a cross-lagged longitudinal design with two waves spaced 1 year apart, we find that, as expected, depression was associated with more Facebook surveillance and more envy, both initially and 1 year later. However, neither Facebook surveillance nor envy at Time 1 increased depression at Time 2. Instead, depression predicted envy, and envy predicted Facebook surveillance over time. The results show the utility of the stress generation hypothesis in a social media context and have implications for Facebook users’ psychological well-being.
