Does global value chain engagement improve firms' wages: Evidence from China
Authors: Lu Yue , Lu Yunlong , Xie Rui , Yu Xiao 
Published: April 2019

AbstractBetter understanding of the effect of the global value chain (GVC) on wages is a key issue for determining welfare gains from engagement in international integration. We study whether and how China's engagement in the GVC enhances firms' wage by using firm‐level and customs transaction‐level data covering the period 2000–06 with the methods of propensity score matching (PSM), difference in differences (DID) and generalised propensity score (GPS). The empirical results show that first, GVC engagement can improve firms' wage. Second, the improvement effect is more prominent in capital‐intensive and foreign‐invested enterprises. Third, the degree of embedment in the GVC shows a U‐shaped relationship with wages (the marginal improvement changes from decreasing to increasing). Finally, by analysing the mechanism, we find that participation in the GVC ultimately improves the overall wage level of enterprises through the productivity effect and the reallocation effect of labour demand.
Surgical site infection associated with equine orthopedic internal fixation: 155 cases (2008–2016)
Authors: Curtiss Alexandra L. , Stefanovski Darko , Richardson Dean W. 
Published: April 2019

AbstractObjectiveTo determine the prevalence of surgical site infection (SSI) after internal fixation and to identify risk factors for SSI and nonsurvival.Study designRetrospective study.AnimalsOne hundred fifty‐five horses with long bone fractures or arthrodesis treated by internal fixation at 1 hospital between 2008–2016.MethodsSignalment, diagnosis, surgical repair, surgeon, surgical time, antimicrobial use, SSI onset, bacterial identification, and adjunct treatments were recorded. Perioperative variables were analyzed to identify risk factors associated with outcomes.ResultsSurgical‐site infection was reported in 22 of 155 (14.2%) horses, which is lower than what has been previously reported (P = .003). Horses with fetlock arthrodesis or ulnar fracture were more likely to develop SSI. Local prophylactic antimicrobial therapy was associated with an increased risk of SSI. Horses with SSI were 12 times (P < .0001) less likely to survive to discharge than horses without SSI. Horses with a fetlock or carpal arthrodesis or those with radial/humeral/femoral fractures were less likely to survive. No association was identified between open fractures, open reduction and internal fixation, or surgical times and SSI.ConclusionThe prevalence of SSI in this population was lower than what has been previously reported. Horses with fetlock or carpal arthrodesis or radial/humeral/femoral fractures were at increased risk for SSI and/or nonsurvival to discharge. A protective role of local antimicrobial therapy for SSI could not be established.Clinical relevanceThe impact of SSI on outcomes of cases of equine internal fixation remains substantial. Identification of cases at higher risk of SSI should influence surgical technique, postoperative management, and early intervention when SSI is suspected. Additional investigation is warranted regarding local antimicrobial therapy.

IntroductionThe Woven EndoBridge Intrasaccular Therapy (WEB-IT) Study is a pivotal, prospective, single-arm, investigational device exemption study designed to evaluate the safety and effectiveness of the WEB device for the treatment of wide-neck bifurcation aneurysms.MethodsOne-hundred and fifty patients with wide-neck bifurcation aneurysms were enrolled at 21 US and six international centers. Angiograms from the index procedure, and 6-month and 1-year follow-up visits were all reviewed by a core laboratory. All adverse events were reviewed and adjudicated by a clinical events adjudicator. A data monitoring committee provided oversight during the trial to ensure subject safety.ResultsOne-hundred and forty-eight patients received the WEB implant. One (0.7%) primary safety event occurred during the study—a delayed ipsilateral parenchymal hemorrhage—on postoperative day 22. No primary safety events occurred after 30 days through 1 year. At the 12-month angiographic follow-up, 77/143 patients (53.8%) had complete aneurysm occlusion. Adequate occlusion was achieved in 121/143 (84.6%) subjects.ConclusionsThe prespecified safety and effectiveness endpoints for the aneurysms studied in the WEB-IT trial were met. The results of this trial suggest that the WEB device provides an option for patients with wide-neck bifurcation aneurysms that is as effective as currently available therapies and markedly safer.Trial registration numberNCT02191618
Identifying the Catalysts for Systematic Deprivation of Hindu Women’s Right to Property: An Appraisal from the Political Contours of Bangladesh
Authors: Al-Ifran Hossain Mollah 
Published: April 2019

Abstract
Hindu women’s limited right to inheritance in Bangladesh is a story of state-sponsored deprivation; a frustrating legacy of the political authority’s systematic indifference and failure in protecting minority women’s right to property for nearly half a century. Bangladesh, from its early decades, has experienced the resurgence of religion as one of the driving factors behind gender and minority-sensitive policy formulation and implementation. Under the veil of constitutional secularism, religion has become one of the most pervasive tools in the hands of the political authorities for methodical marginalisation of religious minority groups especially of Hindu community. Consequently, Bangladesh has failed to move forward with appropriate legislative measures for improving the present status of Hindu women’s right to property. This article argues that the underlying reasons behind such failure is intrinsically intertwined with power-centric electoral politics rather than normative socio-religious practices.
The effect of macrophytic cover on survival of Palaemonetes pugio and P. vulgaris (grass shrimp) in the presence of predatory Fundulus heteroclitus (killifish)
Authors: Merchant Henry C. , Khan Ritindra N. , Knowlton Robert E. 
Published: April 2019

Effects of three different macrophytic covers and the presence of alternative prey on survival of grass shrimp (Palaemonetes pugio and P. vulgaris) subjected to predation by killifish (Fundulus heteroclitus) were studied in the laboratory. Overall, survival of P. vulgaris was significantly greater (82%) than that of P. pugio (70%). This difference in survival was attributed to the greater tendency of P. pugio to swim outside the covers, making it more vulnerable to predation. Both prey species responded similarly to the different cover conditions. Survival without cover (gravel substrate) was 48%. In cover provided by a plastic plant made to resemble Ambulia, 75% of the starting population survived. In cover furnished by field-collected specimens of the flat chlorophyte, Ulva, survival was 71%, compared to 98% survival in the branched green alga, Codium. Predation pressure on neither species was significantly enhanced or diminished by the presence of a second prey species.
For both grass shrimp species, increased survival in Codium in the presence of the predator was attributed to the physically more complex nature of this macrophytic cover.
The Global Political Economy of Fractured Regions
Authors: Ohanyan Anna 
Published: April 2019

Abstract
Despite ebbs and flows in comparative regional studies over the past few decades, the regional dimension of world politics is gaining sustained attention from scholarly and policymaking communities. Thus far much of the focus has been on regional integration, which is traditionally viewed as a necessary condition for economic development and security provision. This article describes the problem of regional fracture in conflict regions; it delineates the political and economic dimensions of regional fracture; and examines the security implications of each. It examines the problem of fractured regions in Russia’s post-Soviet neighborhoods, the Balkans, and sub-Saharan Africa. The article concludes with implications for security policy as exercised by the West in the post-American world.
From Norm Contestation to Norm Implementation: Recursivity and the Responsibility to Protect
Authors: Jacob Cecilia 
Published: April 2019

Abstract
This article contributes to the burgeoning norms literature in international relations that conceptualizes the norm life cycle as a nonlinear dynamic process that is open to contestation and change of “meanings in use.” There are limitations to this second generation of norms theory, however, most crucially in the identification of agency and process through which dialogue occurs and change is enacted. This article claims that to conceptualize the move from norm contestation as dialogic process to norm implementation as a process that weaves norms into the fabric of institutions in their day-to-day politics and routine practices, there is a need to bring IR norms theory into a fruitful engagement with sociological theory on lawmaking. Sociolegal approaches account for institutional processes that move toward the firming up of norms even if hard law status is not the formal objective. This article applies a sociolegal framework of the recursivity of lawmaking to better understand the current diversification of responsibility to protect implementation efforts across the UN and at the national level.
Experiences with >50,000 Crowdsourced Hail Reports in Switzerland

Published: April 2019

AbstractCrowdsourcing is an observational method that has gained increasing popularity in recent years. In hail research, crowdsourced reports bridge the gap between heuristically defined radar hail algorithms, which are automatic and spatially and temporally widespread, and hail sensors, which provide precise hail measurements at fewer locations. We report on experiences with and first results from a hail size reporting function in the app of the Swiss National Weather Service. App users can report the presence and size of hail by choosing a predefined size category. Since May 2015, the app has gathered >50,000 hail reports from the Swiss population. This is an unprecedented wealth of data on the presence and approximate size of hail on the ground. The reports are filtered automatically for plausibility. The filters require a minimum radar reflectivity value in a neighborhood of a report, remove duplicate reports and obviously artificial patterns, and limit the time difference between the event and the report submission time. Except for the largest size category, the filters seem to be successful. After filtering, 48% of all reports remain, which we compare against two operationally used radar hail detection and size estimation algorithms, probability of hail (POH) and maximum expected severe hail size (MESHS). The comparison suggests that POH and MESHS are defined too restrictively and that some hail events are missed by the algorithms. Although there is significant variability between size categories, we found a positive correlation between the reported hail size and the radar-based size estimates.
Moving towards strategic commissioning: impact on clinical commissioning groups as membership organizations

Published: April 2019

Objective This paper aims to explore the nature of clinical commissioning groups (CCGs) in England as membership organizations. Utilizing the concept of meta-organization as a lens, we discuss the impact that this organizational form might have on CCGs’ ability to become ‘strategic commissioners’. Methods We used a longitudinal qualitative approach to explore the adoption and implementation of primary care co-commissioning. The study was undertaken between May 2015 and June 2017 and included interviews with senior policy makers, analysis of policy documents, two telephone surveys, and case studies in four CCGs nationally. Results CCGs operate as membership organizations with closed boundary and low stratification, whereby a consensus or majority needs to be reached by members when activities impact on membership or the CCG’s constitution. While CCGs should move towards a more strategic commissioning role that is focused on local priorities agreed by their members, they are faced with a complex system of accountabilities and responsibilities, which makes this difficult to achieve. Conclusions The nature of CCGs as membership-based meta-organizations has the potential to both help and hinder CCGs in becoming strategic commissioners. The complexities in accountability and governance that the membership approach introduces, and the potential difficulties that CCGs face with competing meta-organizations, raises questions about the future of CCGs as membership organizations.

Abstract
CD34+ cell dose is critical for cord blood (CB) engraftment. However, the CD34+ content of the CB inventory in the United States is unknown. We examined the CD34+ cell content of 126 341 red blood cell–depleted US units banked from January 2007 to September 2017 with a total nucleated cell (TNC) count of ≥90 × 107 and a cryovolume of 24-55 mL. Median pre-cryopreservation TNC content was 127 × 107 (interquartile range [IQR], 108-156 × 107); CD34+ cell content was 44 × 105 (IQR, 29 to 67 × 105). The median CD34+:TNC ratio was 0.34%. TNC and CD34+ cell content correlation was weak (r = 0.24). Of 7125 units with TNCs of ≥210 × 107, only 47% had CD34+ content of ≥100 × 105. However, some units had high CD34+ content for a given TNC count. Only 4% of CB units were acceptable as single-unit grafts (TNCs, ≥2.5 × 107/kg; CD34+ cells, ≥1.5 × 105/kg) for 70-kg patients; 22% of units were adequate for 70-kg patients using lower dose criteria (TNCs, ≥1.5 × 107/kg; CD34+ cells, ≥1.0 × 105/kg) suitable for a double-unit graft. These findings highlight that units with the highest TNC dose may not have the highest CD34+ dose, units with unexpectedly high CD34+ content (a ratio of &gt;1.0%) should be verified, and the US CB inventory of adequately sized single units for larger patients is small. They also support the ongoing use of double-unit grafts, a focus on banking high-dose units, and development of expansion technologies.
Vitamin D in schizophrenia and depression: a clinical review
Authors: Lally John , Gaughran Fiona 
Published: April 2019

SUMMARYEvidence from preclinical and clinical studies supports a role for vitamin D deficiency in many mental disorders. In this review, we discuss the role of vitamin D in the aetiology and treatment of schizophrenia and depression and their physical health comorbidities. Although observational studies support a potential association between vitamin D and schizophrenia and depression, sufficient high-quality evidence from clinical trials does not yet exist to establish a place for vitamin D supplementation in optimising clinical response or promoting physical health. Completed randomised controlled trials are needed to provide insights into the efficacy and safety of vitamin D in the management of mental disorders.LEARNING OBJECTIVESAfter reading this article you will be able to:

PURPOSE The primary objective was to determine if vaginal cuff brachytherapy and chemotherapy (VCB/C) increases recurrence-free survival (RFS) compared with pelvic radiation therapy (RT) in high-intermediate and high-risk early-stage endometrial carcinoma. PATIENTS AND METHODS A randomized phase III trial was performed in eligible patients with endometrial cancer. Eligible patients had International Federation of Gynecology and Obstetrics (2009) stage I endometrioid histology with Gynecologic Oncology Group protocol 33–based high-intermediate–risk criteria, stage II disease, or stage I to II serous or clear cell tumors. Treatment was randomly assigned between RT (45 to 50.4 Gy over 5 weeks) or VCB followed by intravenous paclitaxel 175 mg/m2 (3 hours) plus carboplatin (area under the curve, 6) every 21 days for three cycles. RESULTS The median age of the 601 patients was 63 years, and 74% had stage I disease. Histologies included endometrioid (71%), serous (15%), and clear cell (5%). With a median follow-up of 53 months, the 60-month RFS was 0.76 (95% CI, 0.70 to 0.81) for RT and 0.76 (95% CI, 0.70 to 0.81) for VCB/C (hazard ratio, 0.92; 90% confidence limit, 0.69 to 1.23). The 60-month overall survival was 0.87 (95% CI, 0.83 to 0.91) for RT and 0.85 (95% CI, 0.81 to 0.90) for VCB/C (hazard ratio, 1.04; 90% confidence limit, 0.71 to 1.52). Vaginal and distant recurrence rates were similar between arms. Pelvic or para-aortic nodal recurrences were more common with VCB/C (9% v 4%). There was no heterogeneity of treatment effect with respect to RFS or overall survival among clinical or pathologic variables evaluated. CONCLUSION Superiority of VCB/C compared with pelvic RT was not demonstrated. Acute toxicity was greater with VCB/C; late toxicity was similar. Pelvic RT alone remains an effective, well-tolerated, and appropriate adjuvant treatment in high-risk early-stage endometrial carcinomas of all histologies.
Generalizations of 3-Sasakian manifolds and skew torsion
Authors: Agricola Ilka , Dileo Giulia 
Published: April 2019

Abstract
In the first part, we define and investigate new classes of almost 3-contact metric manifolds, with two guiding ideas in mind: first, what geometric objects are best suited for capturing the key properties of almost 3-contact metric manifolds, and second, the new classes should admit ‘good’ metric connections with skew torsion. In particular, we introduce the Reeb commutator function and the Reeb Killing function, we define the new classes of canonical almost 3-contact metric manifolds and of 3-(α, δ)-Sasaki manifolds (including as special cases 3-Sasaki manifolds, quaternionic Heisenberg groups, and many others) and prove that the latter are hypernormal, thus generalizing a seminal result of Kashiwada. We study their behaviour under a new class of deformations, called 𝓗-homothetic deformations, and prove that they admit an underlying quaternionic contact structure, from which we deduce the Ricci curvature. For example, a 3-(α, δ)-Sasaki manifold is Einstein either if
α = δ (the 3-α-Sasaki case) or if δ = (2n + 3)α, where dim M = 4n + 3.
In the second part we find these adapted connections. We start with a very general notion of φ-compatible connections, where φ denotes any element of the associated sphere of almost contact structures, and make them unique by a certain extra condition, thus yielding the notion of canonical connection (they exist exactly on canonical manifolds, hence the name). For 3-(α, δ)-Sasaki manifolds, we compute the torsion of this connection explicitly and we prove that it is parallel, we describe the holonomy, the ∇-Ricci curvature, and we show that the metric cone is a HKT-manifold. In dimension 7, we construct a cocalibrated G
2-structure inducing the canonical connection and we prove the existence of four generalized Killing spinors.

Abstract
This paper deals with an inverse source problem for an elliptic equation, using interior measurements.
Its motivation lies in the seawater intrusion phenomenon, where we are interested in identifying point sources representing illegal wells.
A cost function transforming our inverse problem into an optimization one is proposed, and numerical results are performed for a rectangular domain.
Autocratic Survival Strategies: Does Oil Make a Difference?
Authors: Ishak Phoebe W. 
Published: April 2019

AbstractThis paper examines the behavior of dictators when faced by an imminent threat of being overthrown in oil abundant countries. In the short run, the dictator’s survival strategies is argued to be confined to public spending and repression, whereas the choice of their levels is conditional upon the intensity of the mass threat (i.e. civil protest vs. mass violence) and the size of oil wealth. The empirical results indicate a possibility of mixing between spending and repression, and that oil wealth allows for differences in their employed levels in face of the same threat. Using a dataset of authoritarian regimes in 88 countries from 1981 to 2006, I found that mass violence is handled through increasing both spending and repression, whereas civil protest is only met by repression. Furthermore, greater oil wealth is found to provide a wider fiscal space to relatively increase spending, but only at low and intermediate levels of mass threats. As the threats intensify, the effect of oil wealth dissipates and oil wealth dictatorships behave the same as their non-oil wealth counterparts.
