Published: January 2021

AbstractResearch has demonstrated that increases in testosterone (T) concentration can affect the expression of behaviours and preferences that are typical of high mating effort. However, little research has considered whether such T increases affect mating strategy more generally and whether this is achievable using a physical intervention. In this pilot study, we examined whether exercise-induced changes in T covary with, or predict, changes in male mating strategy. Healthy young men (N = 94) completed a measure of short- and long-term relationship preference, before and after a series of short cycling sprints. Salivary T was measured pre- and post-exercise, along with salivary cortisol (C), which is known to moderate some behavioural effects of T. A significant group-level increase in T was observed, though this was smaller than anticipated (~ 10%, d = 0.27) with substantial intragroup variation. No group-level change in C or mating preferences emerged. Testosterone change did not significantly predict a change in short- or long-term mating preference from baseline, even with inclusion of C change as a moderator. The current findings suggest that modest exercise-induced increases in T concentration have little impact on male mating strategies. Pharmaceutical interventions, which produce larger and more consistent T increases, may be required to observe mating strategy change.
Automated Full-Pattern Summation of X-Ray Powder Diffraction Data for High-Throughput Quantification of Clay-Bearing Mixtures
Authors: M. Butler Benjamin , Hillier Stephen 
Published: January 2021

AbstractX-ray powder diffraction (XRPD) is found consistently to be the most accurate analytical technique for quantitative analysis of clay-bearing mixtures based on results from round-robin competitions such as the Reynolds Cup (RC). A range of computationally intensive approaches can be used to quantify phase concentrations from XRPD data, of which the ‘full-pattern summation of prior measured standards’ (FPS) has proven accurate and parsimonious. Despite its proven utility, the approach often requires time-consuming selection of appropriate pure reference patterns to use for a given sample. As such, applying FPS to large and mineralogically diverse datasets is challenging. In the present work, the accuracy of an automated FPS algorithm implemented within the powdR package for the R Language and Environment for Statistical Computing was tested on a set of 27 samples from nine RC contests. The samples represent challenging and diverse clay-bearing mixtures with known concentrations, with the added advantage of allowing the accuracy of the algorithm to be compared with results submitted to previous contests. When supplied with a library of 201 reference patterns representing a comprehensive range of phases that may be encountered in natural clay-bearing mixtures, the algorithm selected appropriate phases and achieved a mean absolute bias of 0.57% for non-clay minerals (n = 275), 2.37% for clay minerals (n = 120), and 4.43% for amorphous phases (n = 14). This accuracy would be sufficient for top-3 placings in all nine RC contests held to date (RC1 = 2nd, RC2 = 2nd, RC3 = 1st; RC4 = 2nd; RC5 = 1st; RC6 = 3rd; RC7 = 3rd; RC8 = 1st; RC9 = 2nd). The comparatively low values of absolute bias in combination with the competitive placings in all RC contests tested is particularly promising for the future of automated quantitative phase analyses by XRPD.

Abstract
The estrogen receptor (ER)-negative breast cancer subtype is aggressive with few treatment options available. To identify specific prognostic factors for ER-negative breast cancer, this study included 705,729 and 1034 breast invasive cancer patients from the Surveillance, Epidemiology, and End Results (SEER) and The Cancer Genome Atlas (TCGA) databases, respectively. To identify key differential kinase–substrate node and edge biomarkers between ER-negative and ER-positive breast cancer patients, we adopted a network-based method using correlation coefficients between molecular pairs in the kinase regulatory network. Integrated analysis of the clinical and molecular data revealed the significant prognostic power of kinase–substrate node and edge features for both subtypes of breast cancer. Two promising kinase–substrate edge features, CSNK1A1–NFATC3 and SRC–OCLN, were identified for more accurate prognostic prediction in ER-negative breast cancer patients.
Wages: An Overlooked Dimension of Business and Human Rights in Global Supply Chains
Authors: LEBARON Genevieve 
Published: January 2021

AbstractWages – the monetary payments that workers receive from employers in exchange for their labour – are widely overlooked in academic and policy debates about human rights and business in global supply chains. They shouldn’t be. Just as living wages can insulate workers from human rights abuse and labour exploitation, wages that hover around or below the poverty line, compounded by illegal practices like wage theft and delayed payment, leave workers vulnerable to severe labour exploitation and human rights abuse. This article draws on data from a study of global tea and cocoa supply chains to explore the impact of wages on one of the most severe human rights abuses experienced in global supply chains, forced labour. Demonstrating that low-wage workers experience high vulnerability to forced labour in global supply chains, it argues that the role of wages in shaping or protecting workers from exploitation needs to be taken far more seriously by scholars and policymakers. When wages are ignored, so too is a crucial tool to protect human rights and heighten business accountability in global supply chains.
The relationship between vocal affect recognition and psychosocial functioning for people with moderate to severe traumatic brain injury: a systematic review
Authors: Zupan Barbra , Dunn Leah , Hackney Susanne , Shamshidinova Bahtiyorhon 
Published: January 2021

AbstractThe purpose of this review was to explore how vocal affect recognition deficits impact the psychosocial functioning of people with moderate to severe traumatic brain injury (TBI). A systematic review following the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines was conducted, whereby six databases were searched, with additional hand searching of key journals also completed. The search identified 1847 records after duplicates were removed, and 1749 were excluded through title and abstract screening. After full text screening of 65 peer-reviewed articles published between January 1999 and August 2019, only five met inclusion criteria. The methodological quality of selected studies was assessed using the Mixed Methods Appraisal Tool (MMAT) Version 2018 with a fair level of agreement reached. A narrative synthesis of the results was completed, exploring vocal affect recognition and psychosocial functioning of people with moderate to severe TBI, including aspects of social cognition (i.e., empathy; Theory of Mind) and social behaviour. Results of the review were limited by a paucity of research in this area, a lack of high-level evidence, and wide variation in the outcome measures used. More rigorous study designs are required to establish more conclusive evidence regarding the degree and direction of the association between vocal affect recognition and aspects of psychosocial functioning. This review is registered with Prospero.
Contacts with Police Officers and Changes in Police Legitimacy Perceptions Among Brazilian Adolescents Over Time
Authors: Komatsu André V. , Theodoro Renan , Chies-Santos Mariana , Alvarez Marcos C. 
Published: January 2021

AbstractGrowing research indicates that police legitimacy is a strong predictor of whether people behave respecting or violating rules. Perceptions of legitimacy are an output of socializing processes through which individuals develop their values and orientations toward authorities and the legal system. Legal socialization studies show that encounters with legal authorities are critical “teachable moments” in this process. The present study verifies whether direct or vicarious negative contacts with police officers affect changes in the perception of the legitimacy of police authority by adolescents over time. The adolescents were classified according to whether or not they had witnessed or experienced any negative contact or experience with the police during the period before the interview, composing two group trajectories at the first wave, four at the second wave, and eight at the third wave. Then the trajectories were compared in terms of the extent to which they agree with statements about police legitimacy, allowing the quantification of changes of opinion after negative contacts with the police. Results show that three main factors diminish the perception of police legitimacy: having negative contact with the police; having more than one negative contact; and having a recent negative contact. These findings have important implications for police patrolling and approach strategies.

AbstractBackground:Data on short-term peripheral intravenous catheter–related bloodstream infections per 1,000 peripheral venous catheter days (PIVCR BSIs per 1,000 PVC days) rates from Latin America are not available, so they have not been thoroughly studied.Methods:International Nosocomial Infection Control Consortium (INICC) members conducted a prospective, surveillance study on PIVCR BSIs from January 2010 to March 2018 in 100 intensive care units (ICUs) among 41 hospitals, in 26 cities of 9 countries in Latin America (Argentina, Brazil, Colombia, Costa Rica, Dominican-Republic, Ecuador, Mexico, Panama, and Venezuela). The Centers for Disease Control and Prevention (CDC) National Health Safety Network (NHSN) definitions were applied, and INICC methodology and INICC Surveillance Online System software were used.Results:In total, 10,120 ICU patients were followed for 40,078 bed days and 38,262 PVC days. In addition, 79 PIVCR BSIs were identified, with a rate of 2.06 per 1,000 PVC days (95% confidence interval [CI], 1.635–2.257). The average length of stay (ALOS) of patients without a PIVCR BSI was 3.95 days, and the ALOS was 5.29 days for patients with a PIVCR BSI. The crude extra ALOS was 1.34 days (RR, 1.33; 95% CI, 1.0975–1.6351; P = .040).The mortality rate in patients without PIVCR BSI was 3.67%, and this rate was 6.33% in patients with a PIVCR BSI. The crude extra mortality was 1.70 times higher. The microorganism profile showed 48.5% gram-positive bacteria (coagulase-negative Staphylococci 25.7%) and 48.5% gram-negative bacteria: Acinetobacter spp, Escherichia coli, and Klebsiella spp (8.5% each one), Pseudomonas aeruginosa (5.7%), and Candida spp (2.8%). The resistances of Pseudomonas aeruginosa were 0% to amikacin and 50% to meropenem. The resistance of Acinetobacter baumanii to amikacin was 0%, and the resistance of coagulase-negative Staphylococcus to oxacillin was 75%.Conclusions:Our PIVCR BSI rates were higher than rates from more economically developed countries and were similar to those of countries with limited resources.
Skin carotenoid status and plasma carotenoids: biomarkers of dietary carotenoids, fruits and vegetables for middle-aged and older Singaporean adults

Published: January 2021

AbstractSkin carotenoid status (SCS) measured by resonance Raman spectroscopy (RRS) may serve as an emerging alternative measurement for dietary carotenoid, fruit and vegetable (FV) intake although its application had not been assessed in a middle-aged and older population in Asia. This cross-sectional study aims to concurrently examine the use of SCS and plasma carotenoids to measure FV and carotenoid intake in a middle-aged and older population, taking into consideration potential socio-demographic and nutritional confounders. The study recruited 103 middle-aged and older adults (mean age: 58 years) in Singapore. Dietary carotenoids and FV, plasma carotenoid concentration and SCS were measured using 3-d food records, HPLC and a biophotonic scanner which utilised RRS, respectively. Adjusted for statistically defined socio-demographic covariates sex, age, BMI, prescription medication and cigarette smoking, plasma carotenoids and SCS showed positive associations with dietary total carotenoids (βplasma: 0·020 (95 % CI 0·000, 0·040) µmol/l/mg, P = 0·05; βskin: 265 (95 % CI 23, 506) arbitrary units/mg, P = 0·03) and FV (βplasma: 0·076 (95 % CI 0·021, 0·132) µmol/l per FV serving, P = 0·008; βskin: 1036 (95 % CI 363, 1708) arbitrary units/FV serving, P = 0·003). The associations of SCS with dietary carotenoid and FV intake were null with the inclusion of dietary PUFA, fibre and vitamin C as nutritional covariates (P > 0·05). This suggests a potential influence of these nutritional factors on carotenoid circulation and deposition in the skin. In conclusion, SCS, similar to plasma carotenoids, may serve as a biomarker for both dietary carotenoid and FV intake in a middle-aged and older Singaporean population.
Dwyer–Kan homotopy theory for cyclic operads
Authors: Drummond-Cole Gabriel C. , Hackney Philip 
Published: January 2021

AbstractWe introduce a general definition for coloured cyclic operads over a symmetric monoidal ground category, which has several appealing features. The forgetful functor from coloured cyclic operads to coloured operads has both adjoints, each of which is relatively simple. Explicit formulae for these adjoints allow us to lift the Cisinski–Moerdijk model structure on the category of coloured operads enriched in simplicial sets to the category of coloured cyclic operads enriched in simplicial sets.
A Data Association Algorithm for SLAM Based on Central Difference Joint Compatibility Criterion and Clustering
Authors: Liu Dan 
Published: January 2021

SUMMARYA data association algorithm for simultaneous localization and mapping (SLAM) based on central difference joint compatibility (CDJC) criterion and clustering is proposed to obtain the data association results. Firstly, CDJC criterion is designed to calculate joint Mahalanobis distance. Secondly, ordering points to identify the clustering structure is used to divide all observed features into several groups. Thirdly, CDJC branch and bound method is designed to be performed in each group. The results based on simulation data and benchmark dataset show that the proposed algorithm has low computational complexity and provide accurate association results for SLAM of mobile robot.
Why does the spread of COVID-19 vary greatly in different countries? Revealing the efficacy of face masks in epidemic prevention

Published: January 2021

AbstractThe severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) is highly contagious, and the coronavirus disease 2019 (COVID-19) pandemic caused by it has forced many countries to adopt ‘lockdown’ measures to prevent the spread of the epidemic through social isolation of citizens. Some countries proposed universal mask wearing as a protection measure of public health to strengthen national prevention efforts and to limit the wider spread of the epidemic. In order to reveal the epidemic prevention efficacy of masks, this paper systematically evaluates the experimental studies of various masks and filter materials, summarises the general characteristics of the filtration efficiency of isolation masks with particle size, and reveals the actual efficacy of masks by combining the volume distribution characteristics of human exhaled droplets with different particle sizes and the SARS-CoV-2 virus load of nasopharynx and throat swabs from patients. The existing measured data show that the filtration efficiency of all kinds of masks for large particles and extra-large droplets is close to 100%. From the perspective of filtering the total number of pathogens discharged in the environment and protecting vulnerable individuals from breathing live viruses, the mask has a higher protective effect. If considering the weighted average filtration efficiency with different particle sizes, the filtration efficiencies of the N95 mask and the ordinary mask are 99.4% and 98.5%, respectively. The mask can avoid releasing active viruses to the environment from the source of infection, thus maximising the protection of vulnerable individuals by reducing the probability of inhaling a virus. Therefore, if the whole society strictly implements the policy of publicly wearing masks, the risk of large-scale spread of the epidemic can be greatly reduced. Compared with the overall cost of social isolation, limited personal freedoms and forced suspension of economic activities, the inconvenience for citizens caused by wearing masks is perfectly acceptable.
Effect of antioxidants on preimplantation embryo developmentin vitro: a review
Authors: Zarbakhsh Sam 
Published: January 2021

SummaryIn vitroculture of the embryo is a useful method to treat infertility that shows embryo potential for selecting the best one to transfer and successfully implantation. However, embryo developmentin vitrois affected by oxidative stresses such as reactive oxygen species that may damage embryo development. Antioxidants are molecules found in fruits, vegetables, and fish that play an important role in reducing oxidative processes. In the natural environment, there is a physiological antioxidant system that protects embryos against oxidative damage. This antioxidant system does not existin vitro. Antioxidants act as free radical scavengers and protect cells or repair damage done by free radicals. Various studies have shown that adding antioxidants into embryo culture medium improves embryo developmentin vitro. This review article emphasizes different aspects of various antioxidants, including types, functions and mechanisms, on the growth improvement of different species of embryosin vitro.
Using Social Media to Advance Community-Based Research
Authors: Glazier Rebecca A. , Topping Morgan Paige 
Published: January 2021

ABSTRACTCommunity-based research can improve validity and benefit its subjects, but building trust with communities and research subjects can be challenging. Social media is a powerful tool that can be used to build connections and share information. Yet, little research has been done on how social media can be used as a recruitment and communication tool for community-based research (CBR) projects. Our study used Facebook to advance the goals of a community-based social science research project in Little Rock, Arkansas. We compared participation and results distribution rates for this longitudinal research project in 2012, 2016, and 2018, and we found increases in 2018, the year we used social media. The results indicate that social media can aid CBR by helping to build trust, improve credibility, and facilitate communication.
Impact of Self-Efficacy and Affective Functioning on Pediatric Concussion Symptom Severity

Published: January 2021

AbstractObjective:The purpose of this study was to examine whether self-efficacy predicted pediatric concussion symptom severity and explore whether affective mood states (e.g., depression) influenced this relationship.Method:Children (8–17 years) who were diagnosed with a concussion within 30 days of injury participated in the study (n= 105). Following a clinical assessment, participants and caregivers completed questionnaires that assessed overall concussion symptom severity and current depression symptoms. Participants also completed ratings capturing self-efficacy for managing concussion recovery.Results:Linear regression models revealed that greater levels of self-efficacy predicted lower parent- (R2= 0.10,p= .001) and youth-rated (R2= 0.23,p< .001) concussion symptom severity. Interestingly, depression symptoms moderated the relationship between self-efficacy and concussion symptom severity.Conclusions:Findings provide initial support for a relationship between self-efficacy and concussion outcomes and highlight the influence of depressive symptoms. Interventions that optimize youth’s self-efficacy have the potential to increase treatment adherence, reduce concussion symptom severity, and improve recovery prognosis.

AbstractObjective:Behavioral changes are common after acquired brain injury (ABI) and may be caused by social cognition impairments. We investigated whether impaired emotion recognition, specifically Negative Emotion Recognition (NER) and Anger Misattribution (AM), after ABI was related to behavioral problems, so-called Behaviors of Concern (BoC).Method:The study included 139 participants with ABI and 129 healthy controls. BoC was measured using four scales of the Brock Adaptive Functioning Questionnaire (BAFQ): Impulsivity, Aggression, Social Monitoring, and Empathy. Both self-ratings and informant ratings of BoC were obtained. Emotion recognition was measured with the Ekman 60 Faces Test (FEEST). A NER score was composed of the summed scores on Anger, Disgust, Fear, and Sadness. An AM score was composed of the number of facial expressions wrongly recognized as Anger.Results:Total FEEST scores in ABI participants were significantly worse than in healthy controls. The effect size is moderate. Informants rated significantly more problems in Social Monitoring and Empathy than participants. Effect sizes were small. Scores on FEEST total, NER, and AM were significantly correlated to informant ratings of Social Monitoring. Correlations were weak to moderate.Conclusions:Worse NER and more profound AM were related to more informant-rated problems in social monitoring. In addition, informants rated more problems in social monitoring and empathy than participants. This strongly suggests problems in self-awareness in ABI participants. Consequently, social cognition tests and informant ratings should be used in clinical practice to improve the detection and treatment of BoC after ABI.
