Recipients' happiness in prosocial spending: The role of social ties
Authors: Zhang Wuke , Pan Jing , Liu Jiaoyang , Zhang Yuchen , Chen Mingliang 
Published: June 2020

AbstractIn the past decade, a growing body of studies has explored spenders' happiness in prosocial spending (i.e., spending money on others). However, the happiness of recipients has been frequently ignored. Considering that most prosocial spending behaviors can be seen as a particular form of social interactions and emotional outcomes of social interactions depend on whom people interact with, the current study attempts to explore the influence of the social ties between spenders and recipients (strong vs. weak social ties) on recipients' happiness. More specifically, the present study also attempts to explain this influence from the aspect of basic psychological needs (i.e., relatedness, competence, and autonomy) satisfaction. Results of two studies reveal that gifts from strong social ties lead to recipients' greater happiness than those from weak social ties. Notably, relatedness satisfaction and competence satisfaction, but not autonomy satisfaction, explain this happiness effect of social ties.

AbstractBackgroundSome authors state that above‐normal surface electromyography (SEMG) levels during mandibular rest (MR) are a general sign of temporomandibular disorders (TMD).ObjectiveThe aim was to compare SEMG levels in the masseter and anterior temporalis areas during MR between patients with disc displacement (DD) and subjects identified as healthy. The hypothesis was that average SEMG levels would be higher in the patients during MR before and after repeated clenches with maximal effort.MethodsThirty‐six healthy subjects, and 42 patients with DD, were included. SEMG levels were recorded bilaterally in the temporalis and masseter areas during MR before clenching and after repeated clenches with maximal effort. Multivariate analysis of variance (MANOVA) was used to compare the means of the log‐transformed SEMG‐values for the subject groups.ResultsThe mean MR levels in the four areas before clenching ranged from −0.19 log (µV) to 1.20 log(µV) in healthy subjects and from −0.22 log(µV) to 0.96 log(µV) in patients. The mean MR levels in the four areas after repeated clenches ranged from −0.19 log (µV) to 1.04 log(µV) in healthy subjects and from −0.27 log(µV) to 0.93 log(µV) in patients. The MANOVA test showed no significant differences in the means for MR for the four areas between the groups at the 5% significance level.ConclusionThe hypothesis that jaw muscle SEMG levels during MR are on average generally higher in TMD patients is not supported. A possible explanation for the previous findings is that activity in other muscles was mislabelled as jaw muscle activity.
A service evaluation of the diagnostic testing for mucous membrane pemphigoid in a UK oral medicine unit
Authors: Walton Richard , Robinson Max , Carrozzo Marco 
Published: June 2020

AbstractBackgroundMucous membrane pemphigoid (MMP) is an uncommon bullous disease typically involving the oral cavity. The most commonly used laboratory test for the diagnosis of MMP is direct immunofluorescence (DIF) on fresh perilesional tissue; however, the sensitivity of this test may be hampered by technical difficulties. Immune‐serological investigations can also be employed to render a diagnosis. The purpose of this paper was to present an evaluation of diagnostic testing for MMP within an Oral Medicine Unit in UK.MethodsA retrospective analysis of the medical records was undertaken for patients who had undergone biopsy and DIF testing from January 2016 to December 2018. Parameters analysed included clinical presentation, histopathological features, DIF, salt‐split skin indirect immunofluorescence, ELISA anti‐BP180 and BP 230 and HLA‐DQB1*03:01 findings.ResultsThirty patients (23 females and 7 males, mean age 66.8 years old) were diagnosed with MMP through a combination of histopathology and serological testing. Sixteen patients (53%) were DIF positive, whereas in 14 (47%), MMP diagnosis was achieved using immune‐serologic tests. HLA DQB1*03:01 status was undertaken in 15 DIF‐positive and 12 DIF‐negative patients, and HLA DQB1*03:01 was found in 73% and 58% of the cases, respectively.ConclusionsThis service evaluation has shown that when DIF is informative, it remains the gold standard technique for diagnosis of MMP. However, we have also highlighted the value of serological testing for increasing diagnostic yield for patients with suspected MMP and the potential for HLA DQB1*03:01 as an adjunctive test for the evaluation of MMP.

AbstractBackgroundChianina, Romagnola, and Marchigiana are the 3 most important Italian breeds of cattle raised in the Apennine Mountains. Inherited disorders have been reported in the Chianina and Romagnola breeds but not in the Marchigiana breed. Recently, a case resembling recessively inherited KDM2B‐associated paunch calf syndrome (PCS) in Romagnola cattle was identified in Marchigiana cattle.Hypothesis/ObjectivesTo characterize the features of the observed congenital anomaly, evaluate its possible genetic etiology, and determine the prevalence of the deleterious allele in the Marchigiana population.AnimalsA single stillborn Marchigiana calf was referred for clinicopathological examination because of the presence of PCS‐like morphological lesions.MethodsThe animal was necropsied and the calf and its parents were genotyped. A PCR‐based direct gene test was applied to determine the KDM2B genotype and 114 Marchigiana bulls were genotyped.ResultsThe pathological phenotype included facial deformities, enlarged fluid‐filled abdomen, and hepatic fibrosis. The affected animal was the offspring of consanguineous mating and homozygous presence of the KDM2B missense variant was confirmed. Both parents were heterozygous for KDM2B and the prevalence of carriers in a selected population of Marchigiana bulls was <2%.Conclusions and Clinical ImportanceThe characteristic malformations and genetic findings were consistent with the diagnosis of PCS and provide evidence that the deleterious KDM2B variant initially detected in Romagnola cattle also occurs in the Marchigiana breed.

Published: June 2020

AbstractSoybean is a high inorganic phosphate (Pi) demanding crop; its production is strongly suppressed when Pi is deficient in soil. However, the regulatory mechanism of Pi deficiency tolerance in soybean is still largely unclear. Here, our findings highlighted the pivotal role of the ethylene‐associated pathway in soybean tolerance to Pi deficiency by comparatively studying transcriptome changes between a representative Pi‐deficiency‐tolerant soybean genotype NN94156 and a sensitive genotype Bogao under different Pi supplies. By further integrating high‐confident linkage and association mapping, we identified that Ethylene‐Overproduction Protein 1 (GmETO1), an essential ethylene‐biosynthesis regulator, underlies the major quantitative trait locus (QTL) q14‐2 controlling Pi uptake. GmETO1 was also the representative member of ETO1 family members that was strongly induced by Pi deficiency. Overexpressing GmETO1 significantly enhanced Pi deficiency tolerance by increasing proliferation and elongation of hairy roots, Pi uptake and use efficiency, and conversely, silencing of GmETO1 led to opposite findings. We further demonstrated that Pi‐deficiency inducible genes critical for root morphological and physiological traits including GmACP1/2, Pht1;4, Expansin‐A7 and Root Primordium Defective 1 functioned downstream of GmETO1. Our study provides comprehensive insight into the complex regulatory mechanism of Pi deficiency tolerance in soybean and a potential way to genetically improve soybean low‐Pi tolerance.
Too much of a good thing: Examining the curvilinear relationship between team‐level proactive personality and team performance

Published: June 2020

AbstractResearch has largely shown a positive linear relationship between proactive personality and job performance at the individual level. However, it remains unknown whether the same relationship holds at the team level. In this research, we propose and test a curvilinear relationship between team mean level of proactive personality and team performance. We also examine team potency and team cohesion as the explanatory mechanisms and the dispersion of proactive personality as a boundary condition for the relationship. We conducted two studies to test these ideas. In Study 1, we collected data from 93 teams in four companies from different industries. In Study 2, we collected data from 101 nursing teams in three hospitals. We found a curvilinear relationship between team mean level of proactive personality and team performance in Study 1 and replicated it in Study 2. We further demonstrated in Study 2 the moderating role of dispersion of proactive personality and the mediating role of team potency and team cohesion, respectively, in this curvilinear relationship. The positive trend of the curvilinear relationship is strengthened (weakened) when the dispersion of proactive personality is high (low). The negative trend is mitigated under high dispersion of proactive personality but is not significant under low dispersion of proactive personality. Practically, managers must be aware that team mean level of proactive personality benefits team performance only up to a certain point.
Norms in Counterfactual Selection
Authors: Fazelpour Sina 
Published: June 2020

AbstractIn the hopes of finding supporting evidence for various accounts of actual causation, many philosophers have recently turned to psychological findings about the influence of norms on counterfactual cognition. Surprisingly little philosophical attention has been paid, however, to the question of why considerations of normality should be relevant to counterfactual cognition to begin with. In this paper, I follow two aims. First, against the methodology of two prominent psychological accounts, I argue for a functional approach to understanding the selectivity of counterfactual cognition. Second, I take some steps towards a systematic analysis by providing a qualitative, decision‐theoretic account of one important function of counterfactual thinking, namely, inferring, in the face of undesirable outcomes, corrective policies that prevent the occurrence of similar outcomes in future circumstances. I make a case for employing this analysis by (a) showing its value for assessing the rationality of imagination‐driven counterfactual generation, (b) highlighting its use for making sense of practices in history and policy analysis where counterfactual selection plays a central role, and (c) demonstrating its diagnostic value for identifying areas where counterfactual generation may lead us into epistemic and ethical troubles.

AbstractAimsTo investigate the immunoglobulin (Ig) G response after being fed upon by Cimex lectularius L.Methods and ResultsParticipants were fed upon by three male C lectularius insects weekly for a month. Blood was obtained before the feeding and at the last feeding, which was used for immunoblots against bed bug salivary gland extract, with antihuman Immunoglobulin G (IgG) secondary antibodies. No consistent IgG changes developed in 11 humans serially fed upon by C lectularius. Two participants had new IgG responses to proteins at molecular weights of approximately 12‐13 kDa, and one had an IgG response to a protein at approximately 40 kDa. At the last study visit, more intense IgG bands to proteins at molecular weights of 12‐13 kDa had developed in 55% of participants (6/11) and at molecular weights of ≈30, ≈40 and ≈70 kDa in 45% (5/11) compared with the first study visit. Nitrophorin and apyrase were the most common C lectularius proteins identified with liquid chromatography‐tandem mass spectrometry in both crushed bed bug salivary gland extract and post–bed bug feeding extract.ConclusionsHuman participants did not have consistent IgG responses to crushed C lectularius salivary gland extract.

AbstractBackgroundPyogenic liver abscesses in liver transplant recipients (PLA‐LTR) are a rare disease whose specificities compared with PLA in non‐transplanted patients (PLA‐C) are unknown.MethodsA retrospective case‐control study was conducted in a French academic hospital from January 1, 2010, to December 31, 2014.ResultsAmong 176 patients diagnosed with PLA, 14 were LTR; each case was matched with 3 PLA‐C controls by date of PLA diagnosis and pathophysiological mechanism of PLA. Median time from liver transplantation to PLA diagnosis was 34.5 months. Among 14 PLA‐LTR, 8/14 (57.1%) had bacteremia and 10/14 (71.4%) had positive PLA cultures. Most commonly isolated bacteria were Enterobacteriaceae (9/14; 64.3%), Enterococcus spp. (4/14; 28.6%), and anaerobic bacteria (3/14; 21.4%). Clinical, radiological, and microbiological characteristics did not significantly differ between PLA‐LTR and PLA‐C but there was a tendency toward more diabetic patients and a less acute presentation. All but one PLA‐LTR were associated with ischemic cholangitis, whereas this was a rare cause among PLA‐C (13/14 vs 3/42, respectively, P < .001) among patients with PLA‐LTR. In contrast, hepatobiliary neoplasia was rare in PLA‐LTR but frequent in PLA‐C (1/14 vs 24/42, P = .001). No significant difference was found between PLA‐LTR and PLA‐C in terms of duration of antibiotic therapy (6.5 and 6 weeks, respectively), PLA drainage rates (10/14 and 26/42, respectively), or mortality at 12 months after PLA diagnosis (2/14 and 5/42, respectively). Recurrence rates within the first year were observed in 6/14 patients (42.9%), and retransplantation was needed in 5/14 (35.7%).ConclusionsOccurrence of PLA in LTR is a severe event leading to high risk of recurrence and retransplantation.
Reticencias e inexactitudes en el contrato de seguro: breve comparación de la jurisprudencia de la Corte Suprema de Justicia y de la Superintendencia Financiera
Authors: Tejeiro Carrillo David Augusto 
Published: June 2020

Con ocasión de la atribución de funciones jurisdiccionales a la Superintendencia Financiera de Colombia, se ha dado paso a la creación de una jurisdicción especializada en materias cuyo juez natural, dentro de la justicia ordinaria, no conocía, aparentemente, a profundidad, y, en esa medida, generaba desconfianza en los distintos sectores expuestos a sus decisiones.
Transcurridos más de cinco años desde la entrada en vigencia de la Ley 1480 de 2011, que, en su artículo 57, introdujo esta facultad en la Superintendencia, se procederá a establecer las distintas posiciones adoptadas por el juez ordinario (Corte Suprema de Justicia – Sala de Casación Civil) y el juez especializado, en lo relacionado al contrato de seguro, y más específicamente, en lo referente a las reticencias e inexactitudes que de éste se desprenden.

El ensayo se presenta como el resultado de un análisis crítico de algunos casos representativos del manejo de la Responsabilidad Civil en los Tribunales de Justicia de Costa Rica. Para ello se ha incorporado el análisis de casos tramitados en otros países, en los cuales se resuelven situaciones similares, pero con resultados distintos. La propuesta es que las acciones de otros países sirvan como referencia, como lecciones aprendidas. El aporte de este análisis es referencial e intenta hacer un incentivo para el aprendizaje y asesoría en materia de seguros y administración de riesgos, para lograr una buena gestión de los mismos, en particular y especialmente, lo que se refiere a los posibles daños a terceros causados en la construcción o por Responsabilidad Civil.
Riesgos y seguros de caución para grandes proyectos
Authors: Von Lücken González Eberhard S. 
Published: June 2020

Cabe señalar que las normas imperativas emergen en tal sentido que, ellas tutelan a la parte más débil de la relación jurídica, en este caso el asegurado. En la legislación chilena las normas imperativas no perjudican ante el surgimiento de coberturas de seguros de caución en grandes proyectos. En Paraguay la imperatividad de las normas no se desplaza ante la figura de grandes proyectos por sí. Sin embargo hemos hecho notar que los jueces sin analizar la figura del imperativismo, incluso en pequeños o medianos proyectos, hacen valer los acuerdos de las partes en virtud a un principio sustentado por el Art. 715 del Código Civil que da el carácter de ley a los acuerdos entre las partes, sin embargo no observan en sus fallos que el Art. 669 del mismo cuerpo legal obliga a la observancia de las normas imperativas, norma concordante con el Art. 1692 que resguarda las normas imperativas en materia de seguros, las que solo podrán ser dejadas sin efecto o modificadas, en los casos en que este Código expresamente lo autorice. Ahora bien, para los casos de los Tratados Internacionales de Itaipú celebrados entre Paraguay y Brasil y el de Yacyretá celebrado entre Paraguay y Argentina, se manejan dentro de una figura sui generis que le otorga el estatuto jurídico de Organismo de Derecho Internacional Público, las que se manejan dentro del esquema de prelación por sobre otras normas.

Evaporation of a Saltwater Film in a Vertical Channel and Comparison With the Case of the Freshwater
Authors: Belhadj Mohamed A. , Tlili Iskander 
Published: June 2020

Abstract
In this paper, we analyze the evaporation of a seawater film by mixed convection of humid air. The flown plate is heated and the second plate is dry and can exchanges heat with the environment, be isothermal or adiabatic. Using adequate approximations, we build up a nonlinear form of the Navier–Stokes equations, which is specific for the boundary layer case. We take into account the variation of the salt concentration because of the phase change along the vertical channel. Consequently, to find a solution for combined heat and mass transfers through the channel, we use a numerical finite difference method. The effect of salinity on transfer is taken into account. We found that adding salt to freshwater economizes energy to enhance the film temperature, and the latent heat flux is lower. In addition, we show that the influence of film matter quantity is clearer for saltwater when compared with freshwater case. However, we demonstrate that the effect of the film temperature at the entry and supply heating variations reminds constantly if we compare saltwater and freshwater.

Abstract
Tool breakage is a significant issue in micro milling owing to the less stiffness of the micro tool. To cope up with such limitation, precise predictions of dynamic stability, and cutting force have the utmost importance to monitor and optimize the process. In this article, dynamic stability and cutting force are predicted precisely for micro milling of Ti6Al4V by obtaining force coefficients from a novel 3D intermittent oblique cutting finite element method (FEM) simulation considering the influence of tool run out. First, the stability model is modified by incorporating the appropriate values of limiting angles obtained analytically accounting the trajectories of the flutes due to tool run out. This stability model is utilized to select chatter-free parametric combinations for micro milling tests. Next, an improved cutting force model is developed by incorporating the force coefficients obtained from oblique cutting simulation in the mechanistic model and differentiating the whole machining region into three distinct region considering size effect. The force model also considers the effect of increased edge radius of the worn tool, run out, elastic recovery, ploughing, minimum undeformed chip thickness (MUCT), and limiting angles, cumulatively. The proposed dynamic stability and cutting force models based on the oblique cutting simulation show their adequacy by predicting the stability limit and cutting force more precisely, respectively, as compared to those obtained by orthogonal cutting simulation. Besides, the proposed force model for the worn tool is found to be viable as it is closer to the experimental forces, whereas force model without the incorporation of tool wear underestimated the experimental forces.
A Tunable Variable-Torque Compliant Hinge Using Open-Section Shells
Authors: Hampali Shamanth , Pai S Anoosha , Ananthasuresh G. K. 
Published: June 2020

Abstract
This paper is concerned with a compliant-hinge mechanism that can provide a wide range of torque-angle profiles. The mechanism consists of thin-walled open-section shells that are subjected to combined twisting and bending. A pair of open-section shells is so arranged as to get a large rotation about a virtual axis with high stiffness along other axes. A replaceable cam-like guideway regulates the bending of the open-section shells as they twist, thereby generating the desired torque profile. An energy-based, graphical, and computational design method is formulated to obtain the guideway profile for a specified torque profile. A physical prototype is constructed for an assistive chair for the elderly to demonstrate the variable-torque output and the efficacy of the hinge.
