Published: March 2020

AbstractThere is no established hemostasis method or protocol for the transdistal radial approach. Therefore, this study aimed to determine whether “the PreludeSYNC DISTAL” radial compression device (PSD; Merit Medical Systems, Inc., South Jordan, UT) can effectively prevent distal radial artery (dRA) occlusion following catheterization procedures. This retrospective study analyzed patients who underwent hemostasis using the PSD from January 1, 2019, to March 31, 2019. The primary endpoint was occlusion or excessive stenosis of the radial artery (RA) 1 month after catheterization. Pulsatile blood flow and vessel diameters of the dRA and forearm RA (fRA) were measured using vascular ultrasound before and 1 month after catheterization to determine arterial damage. Secondary endpoints were achievement of hemostasis, bleeding, hematoma, aneurysm, neurological abnormality, and functional disturbance of the fingers or hand. Fifty patients (mean age, 70.9 ± 10.7 years; male, 72.0%) were enrolled in this study. Complete hemostasis was achieved in all cases. Total hemostasis time was 161 ± 45 min. No procedure-associated complications were noted. Pulsations of the dRA and fRA were maintained at 1 month. No functional disturbance or neurological abnormality was observed. Vessel diameters of the dRA and fRA were not significantly different before and 1 month after catheterization. No dissection, pseudoaneurysm, or occlusion/stenosis was observed on ultrasound. Distal radial access with a unique device and protocol effectively achieved hemostasis and prevented injury and occlusion of the dRA and fRA.

AbstractOil sands are characterized by shallow burial and extremely high viscosity, whose exploration technologies and production methods are quite different from that of conventional oil and gas. Oil sands with the largest reserve scale and best quality in China are developed in Fengcheng area of Junggar Basin. This paper presents the forming conditions and enrichment rules of oil sands in Fengcheng area. The dividing standards for effective thickness of oil sands are established with exploration technologies like high-density drilling, whole well section coring and the method of weight percentage of bitumen. The geologic reserves of oil sands are calculated with the method of weight percentage of bitumen. Open-pit mining practices and SAGD double horizontal well development tests are carried out, and good effects are obtained in SAGD production. At present, Fengcheng oil sands have been developed on a large scale with SAGD technology.
Stress magnification factor for angular misalignment between plates with welding-induced curvature
Authors: Mancini Federica , Remes Heikki , Romanoff Jani , Reinaldo Goncalves Bruno 
Published: March 2020

AbstractThe construction of lightweight structures poses new design challenges as a result of the different mechanics of deformation experienced by thinner-plated structures. Because of a reduced bending stiffness, thin plates are particularly sensitive to welding-induced distortions, which include a curvature, in addition to the axial and global angular misalignment observed on thick plates. The curvature shape and amplitude determine a local angular misalignment at the welded joint, which causes non-negligible secondary bending effects. Therefore, the commonly used stress magnification factors km solution for flat plates need a further development to include the curvature effect. This study proposes new analytical formulations, which extend the applicability of the existing solutions to the assessment of the structural stress of a curved thin plate under an axial load. The improved formulations are consistent with the geometrical non-linear finite element analysis under compression (up to $\sim 80$∼80% of the buckling limit) and tension (up to the yield strength). A sensitivity analysis is presented in order to show the dominant role of the curvature effect in the estimation of the km factor. Regardless of the load applied, the presence of the curvature causes a flat plate solution inaccuracy greater than 10% when the local angular misalignment is more than 1.25 times higher than the global angular misalignment in the case of a thin and slender structure.
The freedom trap: digital nomads and the use of disciplining practices to manage work/leisure boundaries
Authors: Cook Dave 
Published: March 2020

AbstractThe digital nomad idea of freedom is often a generalised and subjective notion of freedom that imagines a lifestyle and future where the tensions between work and leisure melt away. This paper finds that in practice, digital nomadism is not always experienced as autonomous and free but is a way of living that requires high levels of discipline and self-discipline. The research suggests that digital nomads often overlook the role of disciplining practices when first starting out, and do not foresee how working in sites of leisure and tourism might make managing a balance between work and non-work problematic. Longitudinal ethnographic fieldwork examines the extent of these disciplining practices and reveals that they are utilised to keep work and leisure time separate.
Contraception in chronic kidney disease: a best practice position statement by the Kidney and Pregnancy Group of the Italian Society of Nephrology

AbstractEven though fertility is reduced, conception and delivery are possible in all stages of CKD. While successful planned pregnancies are increasing, an unwanted pregnancy may have long-lasting deleterious effects, hence the importance of birth control, an issue often disregarded in clinical practice. The evidence summarized in this position statement is mainly derived from the overall population, or other patient categories, in the lack of guidelines specifically addressed to CKD. Oestroprogestagents can be used in early, non-proteinuric CKD, excluding SLE and immunologic disorders, at high risk of thromboembolism and hypertension. Conversely, progestin only is generally safe and its main side effect is intramestrual spotting. Non-medicated intrauterine devices are a good alternative; their use needs to be carefully evaluated in patients at a high risk of pelvic infection, even though the degree of risk remains controversial. Barrier methods, relatively efficacious when correctly used, have few risks, and condoms are the only contraceptives that protect against sexually transmitted diseases. Surgical sterilization is rarely used also because of the risks surgery involves; it is not definitely contraindicated, and may be considered in selected cases. Emergency contraception with high-dose progestins or intrauterine devices is not contraindicated but should be avoided whenever possible, even if far preferable to abortion. Surgical abortion is invasive, but experience with medical abortion in CKD is still limited, especially in the late stages of the disease. In summary, personalized contraception is feasible, safe and should be offered to all CKD women of childbearing age who do not want to get pregnant.
WEIGHTED COMONOTONIC RISK SHARING UNDER HETEROGENEOUS BELIEFS
Authors: Liu Haiyan 
Published: March 2020

AbstractWe study a weighted comonotonic risk-sharing problem among multiple agents with distortion risk measures under heterogeneous beliefs. The explicit forms of optimal allocations are obtained, which are Pareto-optimal. A necessary and sufficient condition is given to ensure the uniqueness of the optimal allocation, and sufficient conditions are given to obtain an optimal allocation of the form of excess of loss or full insurance. The optimal allocation may satisfy individual rationality depending on the choice of the weight. When the distortion risk measure is value at risk or tail value at risk, an optimal allocation is generally of the excess-of-loss form. The numerical examples suggest that a risk is more likely to be shared among agents with heterogeneous beliefs, and the introduction of the weight enables us to prioritize some agents as part of a group sharing a risk.
Refugees, Foreign Nationals, andWageni: Comparing African Responses to Somali Migration
Authors: Whitaker Beth Elise 
Published: March 2020

Abstract:Host governments have responded to the migration of Somali refugees throughout Africa in recent decades in different ways. Kenyan policymakers have treated Somalis primarily as a security threat, imposing restrictions on them that especially target this group. In South Africa, where economic and political competition fuel xenophobia, Somalis are part of a larger foreign national population that is seen as having disproportionate economic influence. However, Somali Bantus have been welcomed in Tanzania, which granted them citizenship even as it limited the mobility and activities of other refugees. A comparative analysis suggests that the relative balance among security, economic, political, and normative considerations shapes the extent and scope of host government policies.
Navigating Patchwork Governance: Somalis in Kenya, National Security, and Refugee Resettlement
Authors: Balakian Sophia 
Published: March 2020

Abstract:Refugee resettlement is accomplished through the intersecting administration of state and non-state actors with competing claims and interests. These competing claims are caught between humanitarian imperatives to rescue the most vulnerable refugees on one hand and security demands to protect national borders from those deemed undesirable and undeserving on the other. Based on ethnographic research with Somali refugees in Nairobi from 2013 to 2015, Balakian examines the ways in which refugees maneuver through an unsynchronized assemblage of institutions to which they are subject; she brings this assemblage into relief through ethnographic accounts of Somali refugees as they attempt to navigate the resettlement system and are simultaneously caught in Kenya’s 2014 anti-refugee security operations. Based on this case, the research demonstrates that being subject to multiple, competing governing bodies is central to the condition of statelessness in twenty-first century Africa.
Agency of Somali Migrant Women in Nairobi and Johannesburg: Negotiating Religious and Cultural Identifications in Diasporic Spaces
Authors: Ripero-Muñiz Nereida 
Published: March 2020

Abstract:An ethnographic analysis of two interconnected cities for the Somali diaspora—Nairobi and Johannesburg—helps to uncover alternative narratives about the lives of Somali women and the ways they renegotiate their cultural and religious identities in diasporic contexts, moving beyond the widespread representation of Somali women in the global imagination as helpless victims. Using the domains of marriage and female circumcision, Ripero-Muñiz analyzes how these women exercise their agency while at the same time negotiating the cultural and religious practices of their community. By focusing on the ways in which Somali women re-negotiate their identities, this article helps to locate the agency of women in refugee and migrant communities in sub-Saharan Africa.
Disciplining Member States: EU Loyalty in External Relations
Authors: ECKES Christina 
Published: March 2020

AbstractThis Article argues that the cooperation obligations of the Member States under EU law are best understood as forming part of an overall duty of EU loyalty and elaborates on the consequences of framing it in this way. EU loyalty legally requires Member States to make the common EU interest their own. The Article further demonstrates that EU loyalty is more relevant and more stringently applied in EU external relations than within the EU legal order. Loyalty obligations of the Member States reach into the future, extend to hypothetical situations, and are at a comparatively high level of abstraction aimed to protect the Union's ability to act effectively on the international plane. This limits Member States’ margin of manoeuvre, including when they take unilateral external action within the realm of their retained national competences. The Article explains that this may be functionally justified by the high stakes of non-concerted external action. However, and in particular with the EU's increased external powers and the ever-growing relevance of international cooperation, the stringent application of cooperation requirements should be (better) explicated and justified.

AbstractThe Palaeoproterozoic Birimian Supergroup of the West African Craton (WAC) consists of volcanic belts composed predominantly of basaltic and andesitic rocks and intervening sedimentary basins composed predominantly of wackes and argillites. Mafic metavolcanic rocks and granitoid-hosted enclaves from the Palaeoproterozoic Lawra Belt of Ghana were analysed for geochemical and Sr–Nd isotopic data to constrain the geological evolution of the southeastern part of the WAC. The metavolcanic rocks display mainly tholeiitic signatures, whereas the enclaves show calc-alkaline signatures. The high SiO2 contents (48.6–68.9 wt%) of the enclaves are suggestive of their evolved character. The high Th/Yb values of the samples relative to that of the mantle array may indicate derivation of their respective magmas from subduction-modified source(s). The rocks show positive εNd values of +0.79 to +2.86 (metavolcanic rocks) and +0.79 to +1.82 (enclaves). These signatures and their Nd model ages (TDM2) of 2.31–2.47 Ga (metavolcanic rocks) and 2.39–2.47 Ga (enclaves) suggest they were probably derived from juvenile mantle-derived protoliths, with possible input of subducted pre-Birimian (Archean?) rocks in their source(s). Their positive Ba–Th and negative Nb–Ta, Zr–Hf and Ti anomalies may indicate their formation through subduction-related magmatism consistent with an arc setting. We propose that the metavolcanic rocks and enclaves from the Lawra Belt formed in a similar island-arc setting. We infer that the granitoids developed through variable degrees of mixing/mingling between basic magma and granitic melt during subduction, when blobs of basic to intermediate parental magma became trapped in the granitic magma to form the enclaves.

AbstractIt is proven that, for a wide range of integers s (2 < s < p − 2), the existence of a single wildly ramified odd prime l ≠ p leads to either the alternating group or the full symmetric group as Galois group of any irreducible trinomial Xp + aXs + b of prime degree p.
How citizens evaluate participatory processes: a conjoint analysis
Authors: Christensen Henrik Serup 
Published: March 2020

AbstractThis study examines how characteristics of participatory processes affect citizens’ evaluations of such processes and thereby establish what kind of participatory process citizens demand. The literature on democratic innovations has proposed different criteria for evaluating participatory innovations. What remains unclear, however, is how citizens evaluate these participatory mechanisms. This is here examined in a conjoint analysis embedded in a representative survey of the Finnish population (n= 1050). The conjoint analysis examines the impact of inclusiveness, popular control, considered judgment, transparency, efficiency, and transferability on citizens’ evaluations of participatory processes. Furthermore, it is examined whether the evaluations differ by the policy issues and process preferences of the respondents. The results show that people want transparent participatory processes with face-to-face interaction among participants and expert advice to deal with complicated issues. The participatory processes should also be advisory and should not include too many meetings. These effects appear to be uniform across policy issues and do not depend on the process preferences of citizens.

Abstract

Aims
The aim of this study was to estimate incidence of self-harm presentations to hospitals and their associated hospital costs across England.

Methods
We used individual patient data from the Multicentre Study of Self-harm in England of all self-harm presentations to the emergency departments of five general hospitals in Oxford, Manchester and Derby in 2013. We also obtained cost data for each self-harm presentation from the hospitals in Oxford and Derby, as well as population and geographical estimates from the Office for National Statistics. First, we estimated the rate of self-harm presentations by age and gender in the Multicentre Study and multiplied this with the respective populations to estimate the number of self-harm presentations by age and gender for each local Clinical Commissioning Group (CCG) area in England. Second, we performed a regression analysis on the cost data from Oxford and Derby to predict the hospital costs of self-harm in Manchester by age, gender, receipt of psychosocial assessment, hospital admission and type of self-harm. Third, the mean hospital cost per age year and gender were combined with the respective number of self-harm presentations to estimate the total hospital costs for each CCG in England. Sensitivity analysis was performed to address uncertainty in the results due to the extrapolation of self-harm incidence and cost from the Multicentre Study to England.

Results
There were 228 075 estimated self-harm presentations (61% were female) by 159 857 patients in 2013 in England. The largest proportions of self-harm presentations were in the age group 40–49 years (30%) for men and 19–29 years (28%) for women. Associated hospital costs were approximately £128.6 (95% CI 117.8−140.9) million in 2013. The estimated incidence of self-harm and associated hospital costs were lower in the majority of English coastal areas compared to inland regions but the highest costs were in Greater London. Costs were also higher in more socio-economically deprived areas of the country compared with areas that are more affluent. The sensitivity analyses provided similar results.

Conclusions
The results of this study highlight the extent, hospital costs and distribution of self-harm presentations to hospitals in England and identify potential sub-populations that might benefit from targeted actions to help prevent self-harm and assist those who have self-harmed. They can support national as well as local health stakeholders in allocating funds and prioritising interventions in areas with the greatest need for preventing and managing self-harm.
In Water‐Limited Landscapes, an Anthropocene Exchange: Trading Lakes for Irrigated Agriculture
Authors: Wine Michael L. , Laronne Jonathan B. 
Published: March 2020

AbstractLakes—quintessential features of Earth's surface prized from perspectives of water security, aquatic ecosystems, and recreation alike—are shrinking in water‐limited regions of all of Earth's inhabited continents. Here we assessed Landsat‐derived long‐term decrease in global lake area relative to historical lake extent aiming to determine the role of recent Anthropocene levels of irrigated agriculture in the global phenomenon of lake desiccation. As of 2015, 11% (1.8 · 105km2) of global lake area has already been lost, primarily due to increased water consumption in support of irrigated agriculture in endorheic basins within water‐limited regions. However, current levels of irrigated agriculture portend substantial additional shrinkage of global lakes before reaching new equilibria with present‐day inflows, with an additional 60–130% increase in endorheic lake loss anticipated. The time required for shrinking lakes to attain new equilibria ranges from decades to centuries depending on lake hyposometry. Even a small decrease in lake area can portend lake transition from exorheic to endorheic and dramatic reductions in water quality. Thus, lake area changes severely understate the perilous condition of global lakes. The watershed area contributing to shrinking (endorheic and exorheic) lakes accounts for 18% of Earth's land area, far too large for the irrigated agriculture therein to be transferred elsewhere in order to save these lakes, though continued developments in the efficiency of water consumption in agriculture and urban areas can save significant quantities of water. This suggests that global lake shrinkage may be a harbinger signaling mankind having exceeded Earth's sustainable carrying capacity.
Predicting Imminence of Analog Megathrust Earthquakes With Machine Learning: Implications for Monitoring Subduction Zones

Published: March 2020

AbstractSubduction zones are monitored using space geodesy with increasing resolution, with the aim of better capturing the deformation accompanying the seismic cycle. Here, we investigate data characteristics that maximize the performance of a machine learning binary classifier predicting slip‐event imminence. We overcome the scarcity of recorded instances from real subduction zones using data from a seismotectonic analog model monitored with a spatially dense, continuously recording onshore geodetic network. We show that a 70–85 km‐wide coastal swath recording interseismic deformation gives the most important information on slip imminence. Prediction performances are mainly influenced by the alarm duration (amount of time that we consider an event as imminent), with density of stations and record length playing a secondary role. The techniques developed in this study are most likely applicable in regions of slow earthquakes, where stick‐slip‐like failures occur at time intervals of months to years.
