Interacting urns on a finite directed graph
Authors: Kaur Gursharn , Sahasrabudhe Neeraja 
Published: September 2022

AbstractWe introduce a general two-colour interacting urn model on a finite directed graph, where each urn at a node reinforces all the urns in its out-neighbours according to a fixed, non-negative, and balanced reinforcement matrix. We show that the fraction of balls of either colour converges almost surely to a deterministic limit if either the reinforcement is not of Pólya type or the graph is such that every vertex with non-zero in-degree can be reached from some vertex with zero in-degree. We also obtain joint central limit theorems with appropriate scalings. Furthermore, in the remaining case when there are no vertices with zero in-degree and the reinforcement is of Pólya type, we restrict our analysis to a regular graph and show that the fraction of balls of either colour converges almost surely to a finite random limit, which is the same across all the urns.
Palatal is for happiness, plosive is for sadness: evidence for stochastic relationships between phoneme classes and sentiment polarity in Hungarian
Authors: Benczes Réka , Kovács Gábor 
Published: September 2022

AbstractThe past couple of decades have seen a substantial increase in linguistic research that highlights the non-arbitrariness of language, as manifested in motivated sound–meaning correspondences. Yet one of the challenges of such studies is that there is a relative paucity of data-driven analyses, especially in the case of languages other than English, such as Hungarian, even though the proportion of at least partially motivated words in Hungarian vocabulary is substantial. We address this gap by investigating the relationship between Hungarian phoneme classes and positive/negative sentiment based on 3,023 word forms retrieved from the Hungarian Sentiment Lexicon. Our results indicate that positive polarity word forms tend to contain more vowels, front vowels, continuants, fricatives, palatals, and sibilants. On the other hand, negative sentiment polarity words tend to have more rounded vowels, plosives, and dorsal consonants. While our analysis provides strong evidence for a set of non-arbitrary form–meaning relationships, effect sizes also reveal that such associations tend to be fairly weak tendencies, and therefore sentiment polarity cannot be derived from the relative frequencies of phoneme classes in a deterministic fashion.
Reaching an Optimally Distinctive CSR Strategy: Examining the Antecedents of CSR Scope Conformity and Emphasis Differentiation Among Chinese Publicly Listed Companies
Authors: Zhang Yanlong , Zhou Xiaoyu , Lyles Marjorie A. 
Published: September 2022

ABSTRACTBuilding on recent developments in optimal distinctiveness (OD) research, we identify two dimensions of corporate social responsibility (CSR) practices – CSR scope conformity and CSR emphasis differentiation – and examine the antecedents of both. We theorize that private ownership and enhanced media coverage may increase scope conformity and emphasis differentiation, while such effects may be contingent on industrial context. In socially contested industries, the impact of private ownership on scope conformity will be mitigated, and the impact of media coverage on scope conformity will be amplified. Meanwhile, in highly competitive industries, the impact of private ownership and media coverage on emphasis differentiation will be mitigated. We test our predictions using a database of 942 Chinese publicly listed firms between 2008 and 2016. Our findings imply that the choice of optimal CSR strategy has to be made in accordance with the embedding context. The multidimensionality view of OD enables firms to better orchestrate firms’ strategic positioning along different dimensions of complex practices, which leads to better customization of societal expectations and the industrial competitive landscape.
Variables influencing conditioning-evoked hallucinations: overview and future applications
Authors: Fry Benjamin R. , Roberts Dominic , Thakkar Katharine N. , Johnson Alexander W. 
Published: September 2022

AbstractHallucinations occur in the absence of sensory stimulation and result in vivid perceptual experiences of nonexistent events that manifest across a range of sensory modalities. Approaches from the field of experimental and cognitive psychology have leveraged the idea that associative learning experiences can evoke conditioning-induced hallucinations in both animals and humans. In this review, we describe classical and contemporary findings and highlight the variables eliciting these experiences. We also provide an overview of the neurobiological mechanisms, along with the associative and computational factors that may explain hallucinations that are generated by representation-mediated conditioning phenomena. Through the integration of animal and human research, significant advances into the psychobiology of hallucinations are possible, which may ultimately translate to more effective clinical applications.
Extreme Behaviors of the Tail Gini-Type Variability Measures
Authors: Sun Hongfang , Chen Yu 
Published: September 2022

AbstractFor a bivariate random vector $(X, Y)$, suppose $X$ is some interesting loss variable and $Y$ is a benchmark variable. This paper proposes a new variability measure called the joint tail-Gini functional, which considers not only the tail event of benchmark variable $Y$, but also the tail information of $X$ itself. It can be viewed as a class of tail Gini-type variability measures, which also include the recently proposed tail-Gini functional. It is a challenging and interesting task to measure the tail variability of $X$ under some extreme scenarios of the variables by extending the Gini's methodology, and the two tail variability measures can serve such a purpose. We study the asymptotic behaviors of these tail Gini-type variability measures, including tail-Gini and joint tail-Gini functionals. The paper conducts this study under both tail dependent and tail independent cases, which are modeled by copulas with so-called tail order property. Some examples are also shown to illuminate our results. In particular, a generalization of the joint tail-Gini functional is considered to provide a more flexible version.

Published: September 2022

AbstractThe DNA revolution has energized research on interactions between genes and environments (GxE) by creating indices of G (polygenic scores) that are powerful predictors of behavioral traits. Here, we test the extent to which polygenic scores for attention-deficit/hyperactivity disorder and neuroticism moderate associations between parent reports of their children’s environmental risk (E) at ages 3 and 4 and teacher ratings of behavior problems (hyperactivity/inattention, conduct problems, emotional symptoms, and peer relationship problems) at ages 7, 9 and 12. The sampling frame included up to 6687 twins from the Twins Early Development Study. Our analyses focused on relative effect sizes of G, E and GxE in predicting behavior problems. G, E and GxE predicted up to 2%, 2% and 0.4%, respectively, of the variance in externalizing behavior problems (hyperactivity/inattention and conduct problems) across ages 7, 9 and 12, with no clear developmental trends. G and E predictions of emotional symptoms and peer relationship problems were weaker. A quarter (12 of 48) of our tests of GxE were nominally significant (p = .05). Increasing the predictive power of G and E would enhance the search for GxE.

SummaryThe aim of this study was to assess mitochondrial DNA analysis as a predictor of the pregnancy potential of biopsied preimplantation embryos. The study included 78 blastomeres biopsied from day 4 cleavage stage euploid embryos. The embryo karyotype was confirmed by 24-chromosome preimplantation genetic testing for aneuploidies using the Illumina Next-Generation Sequencing (NGS) system. Mitochondria viability ratios (mtV) were determined from BAM files subjected to the web-based genome-analysis tool Galaxy. From this cohort of patients, 30.4% of patients (n = 34) failed to establish pregnancy. The mean mtV ratio [mean = 1.51 ± 1.25–1.77 (95% CI)] for this group was significantly (P < 0.01) lower compared with the embryo population that resulted in established pregnancies [mean = 2.5 ± 1.82–2.68 (95% CI)]. mtV multiple of mean (MoM) values were similarly significantly (P < 0.01) lower in blastocysts failing to establish pregnancy. At a 0.5 MoM cut-off, the sensitivity of mtV quantitation was 35.3% and specificity was 78.2%. The positive predictive value for an mtV value > 0.5 MoM was 41.4%. This study demonstrates the clinical utility of preimplantation quantification of viable mitochondrial DNA in biopsied blastomeres as a prognosticator of pregnancy potential.

SummaryThe objective of this study was to investigate the effects of adding β-mercaptoethanol (βME) to culture medium of bovine in vitro-produced (IVP) embryos prior to or after vitrification on embryo development and cryotolerance. In Experiment I, Day-7 IVP blastocysts were vitrified and, after warming, cultured in medium containing 0, 50 or 100 μM βME for 72 h. Embryos cultured in 100 μM βME attained higher hatching rates (66.7%) than those culture in 0 (47.7%) and 50 (52.4%) μM βME. In Experiment II, IVP embryos were in vitro-cultured (IVC) to the blastocyst stage in 0 (control) or 100 μM βME, followed by vitrification. After warming, embryos were cultured for 72 h (post-warming culture, PWC) in 0 (control) or 100 μM βME, in a 2 × 2 factorial design: (i) CTRL–CTRL, control IVC and control PWC; (ii) CTRL–βME, control IVC and βME-supplemented PWC; (iii) βME–CTRL, βME-supplemented IVC and control PWC; or (iv) βME–βME, βME-supplemented IVC and βME-supplemented PWC. βME during IVC reduced embryo development (28.0% vs. 43.8%) but, following vitrification, higher re-expansion rates were seen in βME–CTRL (84.0%) and βME–βME (87.5%) than in CTRL–CTRL (71.0%) and CTRL–βME (73.1%). Hatching rates were higher in CTRL–βME (58.1%) and βME–βME (63.8%) than in CTRL–CTRL (36.6%) and βME–CTRL (42.0%). Total cell number in hatched blastocysts was higher in βME–βME (181.2 ± 7.4 cells) than CTRL–CTRL (139.0 ± 9.9 cells). Adding βME to the IVC medium reduced development but increased cryotolerance, whereas adding βME to the PWC medium improved embryo survival, hatching rates, and total cell numbers.
Microtubule-severing protein Fidgetin-like 1 promotes spindle organization during meiosis of mouse oocytes

Published: September 2022

SummaryMicrotubule-severing proteins (MTSPs) play important roles in mitosis and interphase. However, to the best of our knowledge, no previous studies have evaluated the role of MTSPs in female meiosis in mammals. It was found that FIGNL1, a member of MTSPs, was predominantly expressed in mouse oocytes and distributed at the spindle poles during meiosis in the present study. FIGNL1 was co-localized and interacted with γ-tubulin, an important component of the microtubule tissue centre (MTOC). Fignl1 knockdown by specific small interfering RNA caused spindle defects characterized by an abnormal length:width ratio and decreased microtubule density, which consequently led to aberrant chromosome arrangement, oocyte maturation and fertilization obstacles. In conclusion, the present results suggested that FIGNL1 may be an essential factor in oocyte maturation by influencing the meiosis process via the formation of spindles.

AbstractImportanceSingle ventricle CHD affects about 5 out of 100,000 newborns, resulting in complex anatomy often requiring multiple, staged palliative surgeries. Paediatricians are an essential part of the team that cares for children with single ventricle CHD. These patients often encounter their paediatrician first when a complication arises, so it is critical to ensure the paediatrician is knowledgeable of these issues to provide optimal care.ObservationsWe reviewed the subtypes of single ventricle heart disease and the various palliative surgeries these patients undergo. We then searched the literature to detail the general paediatrician’s approach to single ventricle patients at different stages of surgical palliation.Conclusions and relevanceSingle ventricle patients undergo staged palliation that drastically changes physiology after each intervention. Coordinated care between their paediatrician and cardiologist is requisite to provide excellent care. This review highlights what to expect when these patients are seen by their paediatrician for either well child visits or additional visits for parental or patient concern.

Published: September 2022

AbstractBackground:Video emergency calls (VCs) represent a feasible future trend in medical dispatching. Acceptance among callers and dispatchers seems to be good. Indications, potential problems, limitations, and directions of research of adding a live video from smartphones to an emergency call have not been reviewed outside the context of out-of-hospital cardiac arrest (OHCA).Objective:The main objective of this study is to examine the scope and nature of research publications on the topic of VC. The secondary goal is to identify research gaps and discuss the potential directions of research efforts of VC.Design:Following PRISMA-ScR guidelines, online bibliographic databases PubMed, Web of Science, SCOPUS, Google Scholar, ClinicalTrials.gov, and gray literature were searched from the period of January 1, 2012 through March 1, 2022 in English. Only studies focusing on video transfer via mobile phone to emergency medical dispatch centers (EMDCs) were included.Results:Twelve articles were included in the qualitative synthesis and six main themes were identified: (1) cardiopulmonary resuscitation (CPR) guided by VC; (2) indications of VCs; (3) dispatchers’ feedback and perception; (4) technical aspects of VCs; (5) callers’ acceptance; and (6) confidentiality and legal issues.Conclusion:Video emergency calls are feasible and seem to be a well-accepted auxiliary method among dispatchers and callers. Some promising clinical results exist, especially for video-assisted CPR. On the other hand, there are still enormous knowledge gaps in the vast majority of implementation aspects of VC into practice.
Instructor Name Preference and Student Evaluations of Instruction
Authors: Foster Melissa M. 
Published: September 2022

ABSTRACTStudent evaluations of instruction (SEIs) have an important role in hiring, firing, and promotion decisions. However, evidence suggests that SEIs might be influenced by factors other than teaching skills. The author examined several nonteaching factors that may impact SEIs in two independent studies. Study 1 examined whether an instructor’s name preference (i.e., first name versus “Dr.” last name) influenced SEIs in actual courses. Study 2 implemented a two (i.e., instructor name preference: first name or “Dr.” last name) by two (i.e., instructor gender: male or female) by two (i.e., instructor race: white or Black) between-subjects design for SEIs in a hypothetical course. Study 1 found that SEIs were higher when the female instructor expressed a preference for being called by her first name. Study 2 found the highest SEIs for Black male instructors when instructors asked students to call them by their first name, but there was a decrease in SEI scores if they went by their professional title. Administrators should be aware of the various factors that can influence how students evaluate instructors.

AbstractObjectiveLimited studies have investigated cannabis use in patients with obsessive-compulsive disorder (OCD), despite its widespread use by patients with psychiatric illnesses. The aim of this study was to assess the frequency, correlates, and clinical impact of cannabis use in an Italian sample of patients with OCD.MethodsSeventy consecutive outpatients with OCD were recruited from a tertiary specialized clinic. To assess cannabis-related variables, patients completed a questionnaire developed for the purpose of this study, investigating cannabis use-related habits and the influence of cannabis use on OCD symptoms and treatments. A set of clinician and self-reported questionnaires was administered to measure disease severity. The sample was then divided into three subgroups according to the pattern of cannabis use: “current users” (CUs), “past-users” (PUs), and “non-users” (NUs).ResultsApproximately 42.8% of patients reported lifetime cannabis use and 14.3% reported current use. Approximately 10% of cannabis users reported an improvement in OCD symptoms secondary to cannabis use, while 23.3% reported an exacerbation of anxiety symptoms. CUs showed specific unfavorable clinical variables compared to PUs and NUs: a significant higher rate of lifetime use of tobacco, alcohol, and other substances, and a higher rate of pre-OCD onset comorbidities. Conversely, the three subgroups showed a similar severity of illness.ConclusionA considerable subgroup of patients with OCD showed a predisposition towards cannabis use and was associated with some specific clinical characteristics, suggesting the need for targeted consideration and interventions in this population.
CHARACTER STACKS ARE PORC COUNT

Published: September 2022

AbstractWe compute the number of points over finite fields of the character stack associated to a compact surface group and a reductive group with connected centre. We find that the answer is a polynomial on residue classes (PORC). The key ingredients in the proof are Lusztig’s Jordan decomposition of complex characters of finite reductive groups and Deriziotis’s results on their genus numbers. As a consequence of our main theorem, we obtain an expression for the E-polynomial of the character stack.

AbstractThere is optimism that the growing number of women in political office will reorient the focus of international politics toward more social and humanitarian issues. One basis for this optimism is the argument that women legislators hold distinct foreign policy preferences and act on them to affect changes in policy. However, we know little about gender differences in the behavior of individual legislators on these issues. This study investigates the behavior of individual legislators of the United States, one of the most important actors in international politics, in the context of development aid. Analyzing a diverse set of legislative behaviors in the U.S. Congress, we find no evidence that women legislators behave any differently than men with regard to these issues. Beyond its contribution to our understanding of the making and future of American foreign policy, this study contributes to broader debates about women’s representation and foreign policy.
Estimating the Migrating Diurnal Tide Component of Mesospheric Water Vapor

Published: September 2022

AbstractThis work presents a method for estimating the migrating diurnal tide (DW1) component of mesospheric H2O from observations of the temperature tide and zonal‐mean H2O made by the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument. This work first shows that a 2D least‐squares fit on SABER H2O yields an erroneous DW1 due to retrieval algorithm problems. Consequently, the adiabatic displacement method is used. Applying the method to SABER observations and comparing it with Microwave Limb Sounder (MLS) H2O observations reveals that the method reproduces the MLS‐observed H2O DW1 component best in March and June over low‐latitudes in the altitude range between 65 and 75 km where errors range between +5% and +20%. Applying the method for simulations using the Specified Dynamics—Whole Atmosphere Community Climate Model with Ionosphere/Thermosphere eXtension (SD‐WACCM‐X) indicates that in the model, it is best only in March and not in June. Model simulations further showed that in March, theoretical errors due to the vertical advection assumption and aliasing are best at less than +13% for the low‐latitudes and altitudes between 65 and 75 km. These results, therefore, lead to the conclusion that despite the errors in the vertical advection assumption and aliasing, the adiabatic displacement method performs best in estimating mesospheric H2O DW1 with SABER observations during both March equinox and June solstice over the low latitudes between 65 and 75 km. Results also show that SD‐WACCM‐X satisfactorily simulates the H2O DW1 magnitude and mechanisms only in the March equinox period
