5. Impact of the Digital Revolution on Worldwide Energy Consumption
Authors: Barlage Doug , Shoute Gem
Published: March 2021

We Tweet, Facebook, Netflix and YouTube in the palm of our hand. We are aware of the amount of energy that it takes from how many times that we need to recharge our devices. However, this is just the tip of the iceberg. For every joule of energy we expend locally, many more joules are spent in the backbone of the Internet. While our appetite for data has largely been insatiable over the last thirty years, the energy required to sustain this has been held in check by Moore’s Law’s driving creed that density of function in a computer chip increases by two every two years, and energy/function decreases by a similar amount. With that said, this driving relationship between power consumption and computing density is slowing due to a multitude of physical constraints when the density of transistor packing approaches the limits. In the following chapter, the authors examine these relationships and outline some of the challenges that the world is facing as we continue to meet and exceed the expectations of our data-driven world with a finite growth in worldwide power generation capacity.
15. An Intro to Econferences
Authors: Rockwell Geoffrey , Rossier Oliver , Miya Chelsea
Published: March 2021

Flying is one of the most environmentally detrimental activities associated with our research practices. Until recently, even as colleges and universities took steps to green their campuses, conference-related air travel was on the rise. The COVID-19 pandemic forced academics (along with much of the world) back to the ground, but what will happen after travel restrictions are lifted? Will we slip back into old habits? Our reliance on flying is unsustainable, but research depends on open and timely communication of ideas, methods and results. How then can we adapt our conferencing practices to preserve their communicative value while reducing the need to fly so often? The following chapter introduces the econference medium and makes the argument for bringing academic conferences online, and maintaining these efforts after travel restrictions are lifted.
16. Econferences Are Not the Same, but Are They Good Enough?
Authors: Anderson Terry
Published: March 2021

Terry Anderson helped pioneer econferencing with the email-based Bangkok Project event in 1992, which took place just one year after the World Wide Web went public. In the following chapter, he reflects back on the early challenges of the online conference medium and looks ahead to its future. How has the econference evolved from its origins to today? Will online gatherings always feel like a less satisfying version of their traditional, face-to-face counterpart or can they offer conference-goers something unique?
A Pilot Test of the Association between Weather Comfort and Thermocomfort and Time Spent Outdoors
Authors: Harvey Mark L. , MacPhee Victoria
Published: March 2021

Emerging scientific consensus reveals that spending time outdoors promotes wellness. However, several forces impede time spent outdoors, such as opportunity, safety, and adverse weather. While uncomfortable weather intuitively decreases time outdoors, acclimatization research suggests a counterintuitive process: outdoor exposure enhances physiological adaption to adverse weather, thereby increasing perceived comfort in subsequent outings and even during a single outing in some situations, which, in turn, increases time outdoors. Therefore, this study preliminarily investigated whether time spent outdoors is associated with perceptions of weather and ambient temperature, apart from actual weather. This study attempted to isolate the role of self-reported weather comfort and thermocomfort in predicting time spent outdoors by controlling for motivational and social factors. Residing in the same locale, participants were exposed to identical weather conditions. To enhance recall accuracy, participants daily reported time spent outdoors and weather comfort and thermocomfort across a 7-day period, producing 175 time-comfort entries. Cox regression analyses show that greater perceived comfort with weather and greater perceived comfort with the temperature are associated with significantly more time spent outdoors, adjusting for motivational and social factors. Results also show that participants who wanted to go outdoors, as compared with those who had to go outdoors, reported significantly greater weather comfort. Physiological and other relevant research findings on the human relationship with weather contextualize the study’s rationale and results.
Emotional availability in women with bipolar disorder and major depression: A longitudinal pregnancy cohort study
Authors: Aran Pavitra , Lewis Andrew J , Watson Stuart J , Nguyen Thinh , Galbally Megan
Published: March 2021

Objective:

Poorer mother–infant interaction quality has been identified among women with major depression; however, there is a dearth of research examining the impact of bipolar disorder. This study sought to compare mother–infant emotional availability at 6 months postpartum among women with perinatal major depressive disorder, bipolar disorder and no disorder (control).

Methods:

Data were obtained for 127 mother–infant dyads from an Australian pregnancy cohort. The Structured Clinical Interview for the DSM-5 was used to diagnose major depressive disorder ( n = 60) and bipolar disorder ( n = 12) in early pregnancy (less than 20 weeks) and review diagnosis at 6 months postpartum. Prenatal and postnatal depressive symptoms were measured using the Edinburgh Postnatal Depression Scale, along with self-report psychotropic medication use. Mother and infant’s interaction quality was measured using the Emotional Availability Scales when infants reached 6 months of age. Multivariate analyses of covariance examining the effects of major depressive disorder and bipolar disorder on maternal emotional availability (sensitivity, structuring, non-intrusiveness, non-hostility) and child emotional availability (responsiveness, involvement) were conducted.

Results:

After controlling for maternal age and postpartum depressive symptoms, perinatal disorder (major depressive disorder, bipolar disorder) accounted for 17% of the variance in maternal and child emotional availability combined. Compared to women with major depressive disorder and their infants, women with bipolar disorder and their infants displayed lower ratings across all maternal and child emotional availability qualities, with the greatest mean difference seen in non-intrusiveness scores.

Conclusions:

Findings suggest that perinatal bipolar disorder may be associated with additional risk, beyond major depressive disorder alone, to a mother and her offspring’s emotional availability at 6 months postpartum, particularly in maternal intrusiveness.
Personal Proximity and Reactions to Terrorism
Authors: Agerberg Mattias , Sohlberg Jacob
Published: March 2021

In a panel study where one survey was conducted immediately after a terrorist attack in central Stockholm, with over 20,000 participants, we examine the possibility that first-hand experiences with terror increases effects compared to people located elsewhere in Sweden. We use matching and as-if random variation in our data to identify the effect of personal proximity. While we find that people close to the attack perceived themselves as more affected, attesting to the vividness of the experience, we find no evidence of stronger rally effects, greater outgroup dislike, preferences for security policies or emotional effects. The results challenge previous theories on public opinion change in the aftermath of vivid events. In line with prior research, however, the results indicate that public opinion among people across Sweden did change on a range of issues. These general effects occurred uniformly, regardless of geographic location in the country.
Micro-electromechanical system based optimized steering angle estimation mechanism for customized self-driving vehicles
Authors: Butt Muhammad Atif , Riaz Faisal , Khalid Shehzad , Abid Samia , Habib Muhammad Asif , Shafique Sarmad , Han Kijun
Published: March 2021

In an automated steering system of the self-driving vehicles, the steering wheel angle is measured by the absolute angular displacement sensors or relative angle sensors. However, these sensors either encompass global navigation satellite systems (GNSS)/gyroscope – Micro Electromechanical-Sensor (MEMS) based solutions or comprise of the complex gear-based mechanical structure which results in latency and additive bias in the accumulative steering angle assessment. To address these issues, we propose a novel steering angle assessment system based on enhanced gear mechanism along with the adapted rotation paradigm for the customized self-driving vehicles. Additionally, a digital signal processing system has been introduced to resolve the issues in the identification of absolute central and max-bounding steering wheels position in self-driving vehicles. In assistance with the proposed mechanism, an algorithm has also been proposed to optimize the computed steering angle to minimalize the effect of additive bias in the accuracy. The proposed mechanism has been installed in the customized self-driving testbed vehicle and rigor validation has been performed in the straight and curvy road scenarios. Finally, the comparison study has been carried out between the conventional relative sensor and the proposed mechanism to show the accuracy and effectiveness of the proposed mechanism in terms of error rate, stability, and deviation.
Thinking about offender social reintegration: A case study of one NGO programme in the Eastern Cape Province of South Africa
Authors: Muleya Emmison
Published: March 2021

Successful social reintegration is critical if we are to reduce recidivism and crime in general. This voice of people article presents a background case for why effective offender reintegration services are key in South Africa, and the Eastern Cape in particular, through an example of the Offender Reintegration programme rendered by the National Institute of Crime Prevention and Reintegration of Offenders (NICRO). Apart from the paucity of literature on offender reintegration, very few voices from people working directly with these former offenders are ever heard. Therefore, this article seeks to address this gap by contributing to the body of knowledge on offender social reintegration.
Degrading a global COVID-19 contagion: Charting a holistic social work response
Authors: Omorogiuwa Tracy BE , Amadasun Solomon
Published: March 2021

The eclectic nature of social work in addition to the person-in-environment perspective, as well as its biopsychosocial frame, warrants the utilization of a holistic interventionist lens amid the coronavirus pandemic. This is paramount if we intend to prevent and stymie not just the dreaded contagion in itself, but also its rampaging impact on individuals, families, groups and communities. In this essay, we highlight some empowering framework necessary for action and clarify potential ethical concerns. Given the extensive fallout of the COVID-19 pandemic, illustrative guidelines conducive for holistic professional intervention, during and in the aftermath of the disease, are rolled out.

Authors: Vedernikov Alexander , Nasonov Yaroslav , Korotkov Roman , Gusev Sergey , Akhatov Iskander , Safonov Alexander
Published: March 2021

Pultrusion is a highly efficient composite manufacturing process. To accurately describe pultrusion, an appropriate model of resin cure kinetics is required. In this study, we investigated cure kinetics modeling of a vinyl ester pultrusion resin (Atlac 430) in the presence of aluminum hydroxide (Al(OH)3) and zinc stearate (Zn(C18H35O2)2) as processing additives. Herein, four different resin compositions were studied: neat resin composition, composition with Al(OH)3, composition comprising Zn(C18H35O2)2, and composition containing both Al(OH)3 and Zn(C18H35O2)2. To analyze each composition, we performed differential scanning calorimetry at the heating rates of 5, 7.5, and 10 K/min. To characterize the cure kinetics of Atlac 430, 16 kinetic models were tested, and their performances were compared. The model based on the [Formula: see text]th-order autocatalytic reaction demonstrated the best results, with a 4.5% mean squared error (MSE) between the experimental and predicted data. This study proposes a method to reduce the MSE resulting from the simultaneous melting of Zn(C18H35O2)2. We were able to reduce the MSE by approximately 34%. Numerical simulations conducted at different temperatures and pulling speeds demonstrated a significant influence of resin composition on the pultrusion of a flat laminate profile. Simulation results obtained for the 600 mm long die block at different die temperatures (115, 120, 125, and 130 °C) showed that for a resin with a final degree of cure exceeding 95% at the die exit, the maximum difference between the predicted values of pulling speed for a specified set of compositions may exceed 1.7 times.
SWAT everywhere? A response to Jenkins, Semple, Bennell, and Huey
Authors: Walby Kevin
Published: March 2021

This paper is a response to an article on public police special weapons and tactics (SWAT) teams written by Jenkins and colleagues (2020). Jenkins and colleagues are responding to a study showing that tactical units and members are being used more in Canadian policing. For Jenkins and colleagues, not only are SWAT teams being used properly, but drawing from interviews with tactical members they suggest SWAT teams should be used more in the future. This response focuses on conceptual, methodological, and empirical deficiencies in the work of Jenkins and colleagues. This response shows that Jenkins and colleagues ignore social theory, ignore relevant contrary data, are ignorant of the harms of policing, and are ignorant of the violence that Black and Indigenous peoples face from Canadian police. Relatedly, this response offers a criticism of what is called evidence-based policing scholarship. Using the work of Jenkins and colleagues as an example, the argument here is that evidence-based policing scholars are in a conflict of interest because of how closely they work with police and due to the funding they receive from police agencies and justice ministries. This conflict of interest decreases the credibility and trustworthiness of the claims of evidence-based policing scholars. Overall, this response draws attention not only to the harms of public policing and criminalization, but also to how evidence-based policing scholarship is supporting the expansion of violent, harmful, and regressive forms of social control.

Published: March 2021

Objective

Understanding the pattern of population risk for coronavirus disease 2019 (COVID-19) is critically important for health systems and policy makers. The objective of this study was to describe the association between neighborhood factors and number of COVID-19 cases. We hypothesized an association between disadvantaged neighborhoods and clusters of COVID-19 cases.

Methods

We analyzed data on patients presenting to a large health care system in Boston during February 5–May 4, 2020. We used a bivariate local join-count procedure to determine colocation between census tracts with high rates of neighborhood demographic characteristics (eg, Hispanic race/ethnicity) and measures of disadvantage (eg, health insurance status) and COVID-19 cases. We used negative binomial models to assess independent associations between neighborhood factors and the incidence of COVID-19.

Results

A total of 9898 COVID-19 patients were in the cohort. The overall crude incidence in the study area was 32 cases per 10 000 population, and the adjusted incidence per census tract ranged from 2 to 405 per 10 000 population. We found significant colocation of several neighborhood factors and the top quintile of cases: percentage of population that was Hispanic, non-Hispanic Black, without health insurance, receiving Supplemental Nutrition Assistance Program benefits, and living in poverty. Factors associated with increased incidence of COVID-19 included percentage of population that is Hispanic (incidence rate ratio [IRR] = 1.25; 95% CI, 1.23-1.28) and percentage of households living in poverty (IRR = 1.25; 95% CI, 1.19-1.32).

Conclusions

We found a significant association between neighborhoods with high rates of disadvantage and COVID-19. Policy makers need to consider these health inequities when responding to the pandemic and planning for subsequent health needs.
A study on the applicability of pigment digital printing on cotton fabrics
Authors: Ding Yi , Zhendong Wu , Chuanxiong Zhang , Ruobai Xiao , Wenliang Xue
Published: March 2021

In digital printing, the fabric print quality can only be evaluated through the color and pattern of printed fabric after printing. The influence of the physical properties of fabric on the printing effect remains unclear. In this paper, the digital print suitability of cotton fabric was defined, and 14 samples of plain cotton fabrics were taken as research objects. In addition, 11 evaluation indexes of cotton fabrics were selected. The evaluation and prediction model of cotton fabric printability was established by principal component analysis. Furthermore, the prediction results of the model were verified by analyzing the colorimetric data of cotton fabric after printing. The result demonstrated that the evaluation model of printing suitability was applicable and can be used to quickly evaluate the printability of cotton fabrics. Particularly, fabric thickness had the greatest influence on printing permeability. In the case of moderate wicking, the higher the whiteness of cotton fabric, the better the color reproducibility after printing. Additionally, the wicking effect also had a great influence on color performance.

Published: March 2021

This prospective study investigated the predictive validity of the Historical-Clinical-Risk Management–20, Version 3 (HCR-20V3) in a sample of incarcerated males in a Mexico City prison. Data were collected from 114 male adults incarcerated in a medium-security prison in Mexico City. Participants were an average of 36.86 years old ( SD = 9.93 years) and were all born in Mexico. Data collection for HCR-20V3 ratings involved clinical interviews and a review of institutional documents. Aggressive incidents for a 3-month period following each completed risk assessment were collected through document review, self-report follow-up interviews, and guard reports. Participants who engaged in institutional violence during the 3-month follow-up period were given significantly higher summary risk ratings and had higher HCR-20 total scores than the participants who did not engage in violence (area under the curve [AUC] ranged from .71 to .77). The study demonstrated support for the cross-cultural utility of the HCR-20V3 for institutional violence in a Mexican prison.
Environmental impact of personal protective equipment distributed for use by health and social care services in England in the first six months of the COVID-19 pandemic
Authors: Rizan Chantelle , Reed Malcolm , Bhutta Mahmood F
Published: March 2021

Objective

To quantify the environmental impact of personal protective equipment (PPE) distributed for use by the health and social care system to control the spread of SARS-CoV-2 in England, and model strategies for mitigating the environmental impact.

Design

Life cycle assessment was used to determine environmental impacts of PPE distributed to health and social care in England during the first six months of the COVID-19 pandemic. The base scenario assumed all products were single-use and disposed of via clinical waste. Scenario modelling was used to determine the effect of environmental mitigation strategies: (1) eliminating international travel during supply; (2) eliminating glove use; (3) reusing gowns and face shields; and (4) maximal recycling.

Setting

Royal Sussex County Hospital, Brighton, UK.

Main outcome measures

The carbon footprint of PPE distributed during the study period totalled 106,478 tonnes CO2e, with greatest contributions from gloves, aprons, face shields and Type IIR surgical masks. The estimated damage to human health was 239 DALYs (disability-adjusted life years), impact on ecosystems was 0.47 species.year (loss of local species per year), and impact on resource depletion was costed at US $12.7m (GBP £9.3m). Scenario modelling indicated UK manufacture would have reduced the carbon footprint by 12%, eliminating gloves by 45%, reusing gowns and gloves by 10% and maximal recycling by 35%.

Results

A combination of strategies may have reduced the carbon footprint by 75% compared with the base scenario, and saved an estimated 183 DALYS, 0.34 species.year and US $7.4m (GBP £5.4m) due to resource depletion.

Conclusion

The environmental impact of PPE is large and could be reduced through domestic manufacture, rationalising glove use, using reusables where possible and optimising waste management.
Reconstruction of a Large Oncologic Defect Involving Lower Eyelid and Infraorbital Cheek Using MSTAFI Flap
Authors: Lian Chao , Zhang Jun-Zhe , Li Xue-Lei , Liu Xiao-Jun
Published: March 2021

An oncologic defect that includes both the lower eyelid and the infraorbital cheek often results in complex reconstructive problems because its reconstruction involves 2 distinct tissue types and cosmetic subunits. Herein, we first present a novel combination of modified supratrochlear artery forehead island flap and advancement rotation cheek flap enables reconstructing a large oncologic defect of lower eyelid and infraorbital cheek. Although discoid lupus erythematosus affects the skin, the patient had achieved a satisfying color match and an acceptable aesthetic restoration without tumor recurrence. This novel flap has shown to be feasible, reliable, and advantageous alternative to the repair of such defects.

Published: March 2021

Bonebridge (BB) is the first active implantation system for bone conduction that is placed fully under the skin. Experience suggests that BB is characterized by low incidence of postoperative complications. This case report presents a rare case of a 16-year-old girl with incidence of emphysema occurring over the implant 1 year after operation. We performed a computed tomography scan that showed pockets of gas above the floating mass transducer so we provided the revision surgery and sealed the artificial opening with fat from the earlobe and fibrin glue. Since that time, no air has collected in the retroauricular area and the implant has been fully functional.
Under duress: Community and individual as solace and escape in the Middle East
Authors: Anderson Lisa
Published: March 2021

Examination of the fluidity of communal and individual identity in the Middle East and North Africa suggests that such identities are not stable, singular or mutually exclusive but shaped by circumstances, particularly political and economic duress. An approach that adopts the uncertainty principle of quantum mechanics may be more productive in understanding identity politics in the region and in general.
Afghanistan’s Neo-Taliban Puzzle
Authors: Wani Zahoor Ahmad
Published: March 2021

This article examines the emergence of the neo-Taliban and its encroachment in non-Pashtun regions after the debacle of the old Taliban following the post 9/11 US-led NATO intervention in Afghanistan. It seeks to understand what aspirations drive the neo-Taliban and how they have reframed their ideology after 2001, leading to growing acceptance of a future role for the neo-Taliban in Afghanistan, while foreign-led counterinsurgency seems to fail. The article argues that due to the extremely fractious nature and continuing precariousness of the Afghan political climate, the neo-Taliban could emerge as a formidable power, with an agenda of bringing peace and stability to the entire ‘Af-Pak’ region. However, to what extent the neo-Taliban may be successful in countering widely held perceptions that it is a Pashtun nationalist movement, antagonistic to women, dissent and minorities, remains part of the challenging puzzle, as much for analysts as for the movement itself, which is not trusted in terms of delivering good governance in Afghanistan.
Adolescents’ responses to the distress of others: The influence of multiple attachment figures via empathic concern
Authors: Profe Wade B. , Wild Lauren G. , Tredoux Colin
Published: March 2021

Attachment theory provides an informative theoretical description of how prosocial behaviors in response to the distress of others may be socialized. This study aimed to investigate associations between attachment security to mothers, fathers, closest grandparents and peers, and young adolescents’ (a) prosocial responses to others’ distress and (b) global prosocial behaviors, via the mediation of empathic concern. Cross-sectional survey data were obtained from 520 adolescents (aged 11–14) from nine schools in Cape Town, South Africa. Structural equation modeling revealed that a model in which all paths from the attachment variables were routed through empathic concern was superior to a model which proposed only direct effects of attachment on prosocial behavior. Peer and grandparent attachment were significantly associated, through empathic concern, with self-reported helping in response to others’ distress. For teacher-reported global prosocial behavior, the indirect effects of peer and grandparent attachment failed to reach significance. The results provide theoretical insight into the association between secure attachments and prosocial behavior, and highlight the importance of relationships with friends and grandparents in early adolescence.
An evaluation of the experiences of young people in Patient and Public Involvement for palliative care research
Authors: Mitchell Sarah J , Slowther Anne-Marie , Coad Jane , Khan Dena , Samani Mohini , Dale Jeremy
Published: March 2021

Background:

The active involvement of patients and the public in the design and conduct of research (Patient and Public Involvement) is important to add relevance and context. There are particular considerations for involving children and young people in research in potentially sensitive and emotional subject areas such as palliative care.

Aim:

To evaluate the experiences of young people of Patient and Public Involvement for a paediatric palliative care research study.

Design:

Anonymous written feedback was collected from group members about their experiences of Patient and Public Involvement in a paediatric palliative care research study. An inductive thematic analysis of the feedback was conducted using NVivo.

Setting / Participants:

Young people aged 12–22 years who were members of existing advisory groups at a children’s hospital, hospice and the clinical research network in the West Midlands, UK.

Results:

Feedback was provided by 30 young people at three meetings, held between December 2016 and February 2017. Three themes emerged: (1) Involvement: Young people have a desire to be involved in palliative care research, and recognise the importance of the subject area. (2) Impact: Researchers should demonstrate the impact of the involvement work on the research, by regularly providing feedback. (3) Learning: Opportunities to learn both about the topic and about research more widely were valued.

Conclusions:

Young people want to be involved in palliative care research, and recognise its importance. A continuous relationship with the researcher throughout the study, with clear demonstration of the impact that their input has on the research plans, are important.
Comparison of the effective orifice area of prosthetic mitral valves using two-dimensional versus three-dimensional transesophageal echocardiography
Authors: Zhou Lei , Wei Hai-yan , Ge Ya-li , Ding Zheng-nian , Shi Hong-wei
Published: March 2021

Objective

This study compared the continuity equation-based effective orifice area (EOA) of prosthetic mitral valves between two-dimensional (2D) and 3D transesophageal echocardiography (TEE).

Methods

Thirty-four patients without major aortic valve abnormalities underwent mitral valve replacement surgery. The EOAs of prosthetic mitral valves were calculated using the continuity equation with 2D and 3D TEE. For 18/34 patients using a biological valve prosthesis, the EOA of the prosthesis was obtained from commercial records.

Results

The EOA of prosthetic mitral valves significantly varied between the 2D and 3D methods (2.22 ± 0.71 vs 2.35 ± 0.70 cm2, n = 34). The area of the diameter of the left ventricular outflow tract as determined by the 3D method was significantly higher than that by the 2D method (mean difference: −0.14 ± 0.20 cm2), with 95% coherence boundaries of −0.53 and 0.25 cm2. The regression equation for the EOA by 3D and 2D TEE was y = 0.27 + 0.94x, with a good correlation.

Conclusions

The EOA of prosthetic mitral valves is underestimated using the 2D TEE method compared with the 3D TEE method. The 3D-TEE method has the advantage of higher precision over the 2D TEE method, and it may be helpful for better assessment of prosthetic mitral valves intraoperatively.
The Neighborhood Attainment of Mixed-Race Couples across the Black/White Spectrum
Authors: Gabriel Ryan , Rugh Jacob , Spencer Hannah , Lehmann Aïsha
Published: March 2021

With the removal of legal barriers to mixed-race marriage, there has been a consistent increase in the number of Black-White couples. This has coincided with growth in the number of Black-White individuals who have formed couples with a Black or White partner. Little is known, however, about how these couples function within a key area of stratification—neighborhood attainment. We use data from the Home Mortgage Disclosure Act and the U.S. Census to investigate the percentage of Whites and the average income in the neighborhoods of home-purchasing couples defined by their levels of Black and White representation. These couples being White couples, Black-White individuals with White partners, Black-White couples, Black-White individuals with Black partners, and Black couples. Findings reveal that the percentage of Whites and average income in the neighborhoods of couples decrease as couples increase in Black representation. These results have implications for our understanding of the contemporary color line.
Optimization of thermal model and prediction of crystallinity during the laser-assisted tape winding process
Authors: Kou Zhengqi , Xiao Jun , Huan Dajun , Zhu Kang , Yan Lei
Published: March 2021

Laser-assisted tape placement and tape winding represent the most advanced automated manufacturing technologies for thermoplastic composites. It is important to accurately predict the complete thermal history of the manufacturing process, on which many properties of the product are strongly dependent, such as interlaminar bonding strength and crystallization. In this article, a nonlinear two-dimensional transient heat transfer model was established in ANSYS APDL, and a new temperature closed-loop controlled near-infrared laser heat source was described. Most importantly, the thermal contact pairs were introduced following the activation of elements, and the value of interlaminar thermal contact resistance was obtained by fitting an independent experiment and finite element analysis, which greatly optimized the heat transfer process in the direction of thickness. The thermal model was verified by infrared cameras and an online temperature measuring system based on thermocouples. The results of thermal history are in good agreement with the experiment, which were input into the crystallization kinetics model to predict the evolution and distribution of crystallinity in the laser-assisted tape winding process. The calculated results are coincident with the differential scanning calorimeter test very well, and the crystallinity was about 17% higher than that before manufacturing.
Perceptions of Contexts of Intimate Partner Violence Among Young, Partnered Gay, Bisexual and Other Men Who Have Sex With Men in the United States
Authors: Stephenson Rob , Darbes Lynae A. , Rosso Matthew T , Washington Catherine , Hightow-Weidman Lisa , Sullivan Patrick , Gamarel Kristi E.
Published: March 2021

There has been a growth in research illustrating that gay, bisexual, and other men who have sex with men (GBMSM) experience intimate partner violence (IPV) at rates that are comparable to those among heterosexual women. However, the majority of research on IPV among same-sex male couples has focused on adults, and research on the experience of IPV among younger men (those aged under 18), remains at a nascent stage, despite knowledge that IPV is often common among younger men. This article adds to the growing body of literature on IPV among young GBMSM (YGBMSM) through of an analysis of qualitative data from in-depth interviews (IDI) with GBMSM aged 15–19 ( n = 30) in romantic relationships partnerships. The study sought to explore issues of relationship development, relationship contexts, and understandings of IPV. More than one-half of the sample reported experiencing some form of IPV in their current or past relationships. Participants described a range of experiences of IPV, including physical IPV, emotional IPV, sexual IPV, and controlling behaviors. Emotional IPV in the form of negative comments and controlling behaviors such as jealousy were the most commonly reported forms of violence behaviors. Although few participants reported experiencing physical or sexual IPV, several discussed concerns about giving, and partners’ acknowledging, sexual consent. Antecedents to IPV included wanting or feeling pressured to participate in normative development milestones, short-lived relationships, and societal stigma. Interventions that develop content on IPV and that reflect the lived realities of YGBMSM who are experiencing their first relationships are urgently needed. Study findings also support the need for training teachers, health care providers, and parents to identify signs of IPV and provide them with the knowledge and skills to talk to YGBMSM about relationships and violence to reduce IPV.
The interaction between high-level electronic medical record adoption and hospitalist staffing levels: A focus on value-based purchasing
Authors: Li Kate Jiayi , Al-Amin Mona
Published: March 2021

Objective

This study sought to understand the relationship of hospital performance with high-level electronic medical record (EMR) adoption, hospitalists staffing levels, and their potential interaction.

Materials and methods

We evaluated 2,699 non-federal, general acute hospitals using 2016 data merged from four data sources. We performed ordinal logistic regression of hospitals’ total performance score (TPS) on their EMR capability and hospitalists staffing level while controlling for other market- and individual-level characteristics.

Results

Hospitalists staffing level is shown to be positively correlated with TPS. High-level EMR adoption is associated with both short-term and long-term improvement on TPS. Large, urban, non-federal government hospitals, and academic medical centers tend to have lower TPS compared to their respective counterparts. Hospitals belonging to medium- or large-sized healthcare systems have lower TPS. Higher registered nurse (RN) staffing level is associated with higher TPS, while higher percentage of Medicare or Medicaid share of inpatient days is associated with lower TPS.

Discussion

Although the main effects of hospitalists staffing level and EMR capability are significant, their interaction is not, suggesting that hospitalists and EMR act through separate mechanisms to help hospitals achieve better performance. When hospitals are not able to invest on both simultaneously, given financial constraints, they can still reap the full benefits from each.

Conclusion

Hospitalists staffing level and EMR capability are both positively correlated with hospitals’ TPS, and they act independently to bolster hospital performance.
Harder Than You Think: How Outside Assistance Leads to Overconfidence
Authors: Fisher Matthew , Oppenheimer Daniel M.
Published: March 2021

Cognitive ability consists not only of one’s internal competence but also of the augmentation offered by the outside world. How much of our cognitive success is due to our own abilities, and how much is due to external support? Can we accurately draw that distinction? Here, we explored when and why people are unaware of their reliance on outside assistance. Across eight experiments ( N = 2,440 participants recruited from Amazon Mechanical Turk), people showed improved metacognitive calibration when assistance occurred after a delay or required active choice. Furthermore, these findings apply across a wide range of cognitive tasks, including semantic memory (Experiments 1a and 1b), episodic memory (Experiments 2a and 2b), and problem solving (Experiments 3a–3d). These experiments offer important insights into how we understand our own abilities when we rely on outside help.
Towards a new consolidated framework for analysing benefit coverage
Authors: Nelson Kenneth , Nieuwenhuis Rense
Published: March 2021

The conceptualisation and measurement of benefit coverage is muddled with considerable confusion. In this forum contribution, we propose a new consolidated framework for the analysis of benefit coverage. Three sequential steps in measurement are suggested, involving the calculation of coverage rates, eligibility rates and take-up rates in social protection. Each step of the analysis focuses on particular aspects of programme legislation and implementation, and together the new framework will substantially improve the possibilities of research to inform policymaking. We provide an empirical illustration of our approach based on Swedish data, and highlight how our new consolidated framework for analysing benefit coverage provides a reorientation of the research agenda on benefit coverage.
Learning About the World by Learning About Images

One of the deepest insights in neuroscience is that sensory encoding should take advantage of statistical regularities. Humans’ visual experience contains many redundancies: Scenes mostly stay the same from moment to moment, and nearby image locations usually have similar colors. A visual system that knows which regularities shape natural images can exploit them to encode scenes compactly or guess what will happen next. Although these principles have been appreciated for more than 60 years, until recently it has been possible to convert them into explicit models only for the earliest stages of visual processing. But recent advances in unsupervised deep learning have changed that. Neural networks can be taught to compress images or make predictions in space or time. In the process, they learn the statistical regularities that structure images, which in turn often reflect physical objects and processes in the outside world. The astonishing accomplishments of unsupervised deep learning reaffirm the importance of learning statistical regularities for sensory coding and provide a coherent framework for how knowledge of the outside world gets into visual cortex.
Invigorating and Reinventing Sacred Space: Hijra and Non-Hijra Relationships in a Dargah
Authors: Ghosh Banhishikha
Published: March 2021

The article juxtaposes the lived realities and perceptions of a hijra gharana connected to a dargah (shrine of a revered religious figure belonging to the Sufi tradition) in a North Indian city, Narayanpura. It addresses how a hijra community interacts and develops interpersonal relationships with their non-hijra neighbours, devotees and shopkeepers, thereby engendering hijra selfhood. The potent element of symbolism enunciated through mythology, rituals and festivals becomes pertinent in constructing and authenticating the hijra identity. Concomitantly, the spiritual pursuits of these groups are intertwined with their material interests in constructing their complex universe. The monument provides a site where shared connotations for each section of people connected to the dargah, hailing from different cultural, religious and gender orientations, are invigorated. The dargah is, therefore, not only part of the religious system, but it is a system in itself. Data for this article have been accumulated through limited participant observation, unobstructed conversations and narratives of the interlocutors.
Frenemies: Marine Turtle Conservation and Economic Development in the Rushikulya Coast, Eastern India
Authors: Ramesh Madhuri
Published: March 2021

The discourse on biodiversity conservation often presents this domain as an antithesis to economic development. However, in practice, the relation between conservation and development is far more complex because conservationists possess limited powers and must give serious consideration to the economic aspirations of others in any given region, such as local communities and industries. Moreover, conservationists are themselves a heterogeneous group with diverse ways of working. Therefore, although the relation between conservation and development is often described in binary terms such as conflict—co-operation, this does not adequately capture the nuances and dilemmas of actual conservation practice. In this article, I present an ethnographic study of marine turtle conservation in Rushikulya (eastern India), to argue that the relation between the two domains is essentially ambivalent and uncertain and hence, best understood as one of being ‘frenemies’ i.e. friendly enemies, rather than as allies or antagonists. From fieldwork conducted over three years (2012–2015), I describe how actors in both domains opportunistically borrow tools and concepts from each other, which blurs the boundaries between them and results in both connections and contestations. To conclude, I suggest we need more ethnographic studies to understand the realities of practice and provoke reflection on current approaches to both conservation and development.
On Racial Disparities in Child Abuse Reports: Exploratory Mapping the 2018 NCANDS

Research suggests children from non-White and Hispanic/Latinx communities are at higher risk for child maltreatment. This study identified in which states children from specific non-White communities were overrepresented in child protective services reports for child physical, sexual, and emotional/psychological abuse through exploratory mapping. Reports on child maltreatment originated from the 2018 National Child Abuse and Neglect Data System and state-level population estimates from the U.S. Census Bureau. Racial disparities were identified in states with unequal proportions of reported child maltreatment among a non-White child population compared to the proportion among the White child population. We found disparities for children from non-White communities in many states, especially for Black communities (Disparity Ratio [DR]: 15.10 for child physical abuse, DR: 12.77 for child sexual abuse in Washington DC, and DR: 5.25 for child emotional/psychological abuse in California). The ability to identify high disparities among Pacific Islanders highlights one of the study’s strengths, given we separately examined Asian Americans, Pacific Islanders and multiracial communities. Results from our exploratory mapping provide insight into how preventive resources might be differentially allocated to non-White communities with higher child protective services reporting compared with White communities, and manifest states with multiple non-White communities overrepresented across maltreatment types.
Public Attitudes Toward Institutional Child Sexual Abuse in Israel: The Case of Malka Leifer
Authors: Lusky-Weisrose Efrat , Marmor Amitai , Tener Dafna
Published: March 2021

This study examined Israeli public perceptions of institutional child sexual abuse (CSA) in the Malka Leifer case. Leifer is a Jewish ultra-Orthodox former Melbourne school principal who is wanted in Australia on CSA charges, after fleeing to Israel. Based on a qualitative analysis of 2,451 reader comments retrieved from four Israeli news websites and six public Facebook pages, the findings indicated diverse attitudes toward the alleged perpetrator, the ultra-Orthodox Jewish community, state authorities, and victims. All parties involved were criticized, but less so the victims. Criticisms included sociopolitical and gender stereotypes, and demonic attributions. Positive comments were directed at all involved, even the alleged perpetrator, and especially the victims. The results demonstrate the need to better understand CSA portrayals in cyberspace, as they affect both public and policymaker attitudes, and the importance of fighting prejudicial discourse about the ultra-Orthodox community, especially in light of its changing attitudes regarding CSA.
Identifying Barriers to and Facilitators of Using a Mobile Fruit and Vegetable Market Intervention Delivered to Low-Income Housing Sites: A Concept Mapping Study

Background

Mobile fruit and vegetable (F&V) markets may be a promising strategy to improve F&V intake among low-income and racial/ethnic minority groups. However, challenges remain in terms of maximizing the reach and utilization of such markets. Therefore, this study identifies perceived barriers to and facilitators of utilizing a mobile F&V market among residents who lived in low-income housing that received the markets. Specifically, this article reports the results of the follow-up acceptability study of the “Live Well, Viva Bien” (LWVB) intervention.

Method

We conducted concept mapping with residents in housing communities that received the Fresh to You (FTY) markets. Participants generated, sorted, and rated statements concerning barriers to and facilitators of market use. We compared the rating data by residents’ level of market utilization and created a map representing how statements clustered into conceptual themes.

Results

We retained 66 unique participant-generated statements. Eight thematic clusters emerged; four pertained to barriers: financial/promotion, produce-related, scheduling/knowledge, and logistic/awareness barriers, and four related to facilitators: produce/staffing, promotion, accessibility, and multilevel market facilitators. There was a strong correlation in ratings between participants who more frequently versus less frequently shopped at the markets ( r = 0.94).

Conclusions

Participants identified financial barriers, market promotion, ease of market accessibility, produce variety and quality, and staffing as key factors influencing FTY market use. This study highlights the importance of identifying the perceived barriers to and facilitators of mobile F&V market use among target populations to inform future efforts to scale up such approaches.
