Four new water mite species of the genus Hygrobates, subgenus Lurchibates (Acari, Hydrachnidia, Hygrobatidae) are described. Hygrobates (Lurchibates) macrochela sp. nov. Goldschmidt, Nishikawa & Shimano is described in male and female; Hygrobates (Lurchibates) malosimilis sp. nov. Goldschmidt, Nishikawa & Shimano is described in male, both new water mite species were collected from newts of the species Pachytriton inexpectatus Nishikawa, Jiang, Matsui & Mo, 2011; Hygrobates (Lurchibates) incognitus sp. nov. Goldschmidt, Nishikawa & Shimano is described in female collected from newts of the species Paramesotriton guangxiensis (Huang, Tang and Tang, 1983); Hygrobates (Lurchibates) fragmentarius sp. nov. Goldschmidt, Nishikawa & Shimano is described in a single severely fragmented specimen (sex could not be determined) collected from a newt of the species Paramesotriton yunwuensis Wu, Jiang, and Hanken, 2010. Principal differences between the subgenus Lurchibates and the nominal subgenus Hygrobates s. str. are illustrated and discussed as well as the sexual dimorphism of Lurchibates. Morphometric analyses confirmed the morphological differences of ten out of the eleven so far described species (H. (L.) fragmentarius could not be included in the analysis); two morphological groups became evident mainly based upon the shape of the anterior coxae. These analyses as well provide an idea of possible phylogenetic relationships among the species. A key to all currently known species of the subgenus Lurchibates is given. So far the subgenus is restricted to SE-Asia, a map showing the distribution of all species is presented.
Deterioration of concrete containing limestone powder exposed to sulfate attack at ambient temperature
Authors: Liu Hemin , Huang Qian , Zhao Liang
Published: June 2021

This study investigates the deterioration of concrete containing limestone powder exposed to sulfate solution under ambient temperature (20~25 °C). Microstructure and mineral phases within the attacked concrete were measured by scanning electron microscopy (SEM), energy dispersive
spectroscopy (EDS), and X-ray diffraction (XRD). It was found that the addition of limestone powder increased the initial porosity of concrete. Consequently, a larger amount of SO2–4 ions diffused into the concrete containing limestone powder, and their degree of
deterioration caused by sulfate attack increased with the increase in limestone powder content. At ambient temperature, gypsum and ettringite were the major attack products, respectively within the surface and nearsurface portions of concrete containing limestone powder, which was consistent
with the products of sulfate attack within concrete without limestone powder. Therefore, the type and distribution of the attack products in concrete had not been revised due to the addition of limestone powder. Nevertheless, the adverse influence of limestone powder on the sulfate resistance
of concrete, even at ambient temperature, should be considered. Furthermore, effective measures should be implemented to improve the durability of concrete containing limestone powder in this environment.
Vertical fluxes conditioned on vorticity and strain reveal submesoscale ventilation
Authors: Balwada Dhruv , Xiao Qiyu , Smith Shafer , Abernathey Ryan , Gray Alison R.
Published: June 2021

It has been hypothesized that submesoscale flows play an important role in the vertical transport of climatically important tracers, due to their strong associated vertical velocities. However, the multi-scale, non-linear, and Lagrangian nature of transport makes it challenging to attribute proportions of the tracer fluxes to certain processes, scales, regions, or features. Here we show that criteria based on the surface vorticity and strain joint probability distribution function (JPDF) effectively decomposes the surface velocity field into distinguishable flow regions, and different flow features, like fronts or eddies, are contained in different flow regions. The JPDF has a distinct shape and approximately parses the flow into different scales, as stronger velocity gradients are usually associated with smaller scales. Conditioning the vertical tracer transport on the vorticity-strain JPDF can therefore help to attribute the transport to different types of flows and scales. Applied to a set of idealized Antarctic Circumpolar Current simulations that vary only in horizontal resolution, this diagnostic approach demonstrates that small-scale strain dominated regions that are generally associated with submesoscale fronts, despite their minuscule spatial footprint, play an outsized role in exchanging tracers across the mixed layer base and are an important contributor to the large-scale tracer budgets. Resolving these flows not only adds extra flux at the small scales, but also enhances the flux due to the larger-scale flows.
Skills for the Future? A Life Cycle Perspective on Systems of Vocational Education and Training
Authors: Chuan Amanda , Ibsen Christian Lyhne
Published: June 2021

In this article, the authors ask how the institutional design of vocational education and training (VET) affects worker adaptability to changing skill demands over the life cycle. They compare two types of VET systems. Collectivist systems have high employer involvement and focus on specific skills, whereas Statist systems have lower employer involvement and focus more on general skills. Based on prior research demonstrating the importance of general skills in learning new skills, the authors hypothesize that worker adaptability will be higher in Statist VET systems than in Collectivist VET systems. Using a triple-difference model on data from the Program for the International Assessment of Adult Competencies, they find that as age increases, a significantly steeper decline in worker adaptability occurs within Collectivist systems compared to Statist systems. Results provide an explanation behind the diminishing employment returns to employer-dominated VET systems found in prior studies.
Soldier and Scholar: Abdias Nascimento and the Origins of Afro-Latin American Studies
Authors: Morgan Zachary R.
Published: June 2021

Abdias Nascimento shaped Brazil and the lives of Afro-Brazilians as an activist, as a politician, as an internationally recognized scholar, and through the arts as a playwright, a director, a poet, and painter. Through a scholarly career that spanned much of the 20th century and continued into the 21st, his ideas preceded and served as a model for the recent growth of Afro-Latin American studies as a discipline. This article draws on Nascimento’s writing to shed light on the less studied period when he was enrolled in the Brazilian army in São Paulo from 1930 to 1936, as well as the two related periods during which he was incarcerated between 1936 and 1938. This essay argues that—much like Afro-descendant soldiers globally who fought in conflicts from the American Wars of Independence through the World Wars of the 20th century—military service and his subsequent captivity deeply inpacted Abdias Nascimento. His relations with the Brazilian military and its penal institutions guided his concept of race, citizenship, and nation, his activism and scholarship, and subsequently helped mold the contemporary field of Afro-Latin American studies, directly and indirectly.
Is John Henryism a Health Risk or Resource?: Exploring the Role of Culturally Relevant Coping for Physical and Mental Health among Black Americans
Authors: Robinson Millicent N. , Thomas Tobin Courtney S.
Published: June 2021

Research shows that John Henryism, a high-effort, active coping style, is associated with poor physical health, whereas others suggest it may be psychologically beneficial. As such, it is unclear whether John Henryism represents a health risk or resource for black Americans and whether its impact varies across sociodemographic and gender groups. The present study used data from a representative community sample of black Americans (n = 627) from the Nashville Stress and Health Study (2011–2014) to clarify the physical and mental health consequences of John Henryism by assessing its relationship with depressive symptoms and allostatic load (AL). Results indicate that John Henryism is associated with increased AL scores and fewer depressive symptoms. Additionally, the association between John Henryism and AL is conditional on socioeconomic status. Study results underscore the importance of evaluating both physical and mental health to clarify the health significance of John Henryism among black Americans.
Developmental Language Disorder and Psychopathology: Disentangling Shared Genetic and Environmental Influences
Authors: Toseeb Umar , Oginni Olakunle Ayokunmi , Dale Philip S.
Published: June 2021

There is considerable variability in the extent to which young people with developmental language disorder (DLD) experience mental health difficulties. What drives these individual differences remains unclear. In the current article, data from the Twin Early Development Study were used to investigate the genetic and environmental influences on psychopathology in children and adolescents with DLD ( n = 325) and those without DLD ( n = 865). Trivariate models were fitted to investigate etiological influences on DLD and psychopathology, and bivariate heterogeneity and homogeneity models were fitted and compared to investigate quantitative differences in etiological influences on psychopathology between those with and without DLD. The genetic correlation between DLD and internalizing problems in childhood was significant, suggesting that their co-occurrence is due to common genetic influences. Similar, but nonsignificant effects were observed for externalizing problems. In addition, genetic influences on internalizing problems, but not externalizing problems, appeared to be higher in young people with DLD than those without DLD, suggesting that the presence of DLD may exacerbate genetic risk for internalizing problems. These findings indicate that genetic influences on internalizing problems may also confer susceptibility to DLD (or vice versa) and that DLD serves as an additional risk factor for those with a genetic predisposition for internalizing problems.
Policing with a public health lens – Moving towards an understanding of crime as a public health issue
Authors: Bucerius Sandra M , Oriola Temitope B , Jones Daniel J
Published: June 2021

Policing organizations are currently experiencing more pressure than ever to address systemic racism and police brutality. Advocates and academics have suggested a range of changes, such as defunding the police, moving towards more body-worn cameras, ensuring higher educational levels of new recruits, implicit bias training, and so on. Our article draws attention and advocates for a different avenue: moving our understanding of crime towards a public health issue. By drawing on some data from the University of Alberta Prison Project, we argue that looking at justice clients with a public health lens would significantly change the way police are trained and respond to incidents. We believe this would have monumental consequences for both justice clients and policing organizations: justice clients will benefit from a police service that is trauma informed, compassionate, and understands their client base, while policing organizations will arguably increase their trust relationship with the public, therefore building legitimacy in the community.
Investigation of the transport characteristics of Pb(II) in sand-bone char columns
Authors: Li Gang , Zhang Jinli , Liu Jia , Luo Tao , Xi Yu
Published: June 2021

Pb(II) leakage from batteries, dyes, construction materials, and gasoline threaten human health and environmental safety, and suitable adsorption materials are vitally important for Pb(II) removal. Bone char is an outstanding adsorbent material for water treatment, and the effectiveness in Pb(II) removing need to be verified. In this paper, the transport characteristics of Pb(II) in columns filled with a sand and bone char mixture were studied at the laboratory scale, and the influences of the initial concentration, column height, inlet flow rate, and competing ion Cu(II) on Pb(II) adsorption and transport were analyzed. The Thomas and Dose-Response models were used to predict the test results, and the mechanisms of Pb(II) adsorption on bone char were investigated. The results showed that the adsorption capacity of the bone char increased with increasing column height and decreased with increasing initial Pb(II) concentration, flow rate, and Cu(II) concentration. The maximum adsorption capacity reached 38.466 mg/g and the saturation rate was 95.8% at an initial Pb(II) concentration of 200 mg/L, inlet flow rate of 4 mL/min, and column height of 30 cm. In the competitive binary system, the higher the Cu(II) concentration was, the greater the decreases in the breakthrough and termination times, and the faster the decrease in the Pb(II) adsorption capacity of the bone char. The predicted results of the Dose-Response model agreed well with the experimental results and were significantly better than those of the Thomas model. The main mechanisms of Pb(II) adsorption on bone char include a surface complexation reaction and the decomposition-replacement-precipitation of calcium hydroxyapatite (CaHA). Based on selectivity, sensitivity, and cost analyses, it can be concluded that bone char is a potential adsorbent for Pb(II)-containing wastewater treatment.
Collaborating for Equity in Urban Education: Comprehensive Reform in an Innovative University/School Partnership
Authors: Larson Joanne , Nelms Shaun
Published: June 2021

Using data from a participatory ethnography of an urban high school slated for closure, this article examines the impact of comprehensive transformation on the university-school partnership’s goal to change from a culture of underachievement and negativity toward a culture of collaboration and excellence. We explore these question/s: How do comprehensive changes in infrastructure, policies, leadership, and instructional practices shape school culture? What role do shifting power relations (generative frictions) and authentic trust play in developing shared ownership of outcomes? We argue generative frictions produced changes in culture that impacted changes in outcomes.
First, Do No Harm: From Diversity and Inclusion to Equity and Anti-racism in Interpersonal Violence Research and Scholarship
Authors: Tajima Emiko A.
Published: June 2021

This article aims to support interpersonal violence (IPV) researchers in promoting diversity and inclusion in their research and scholarship and urges the IPV field to advance a racial equity, anti-oppressive, and justice-driven research agenda. The article discusses a range of factors to consider at each stage of the research process as researchers seek to be inclusive, responsive to diversity concerns, and seek equity. The researcher’s perspective and positionality are discussed and the importance of critical self-examination of one’s position in relation to the research is emphasized. Participatory and collaborative research processes are recommended, to engage with community partners, strengthen the validity of the findings, and help ensure that the research benefits the participants. Examples illustrate ways researchers might support diversity and inclusion with respect to sampling and measurement, cultural validity, and the conceptualization and operationalization of race. Recommendations are offered to promote diversity, equity, and inclusion when analyzing data, interpreting results, and writing up the study. The importance of a strengths-based approach and structural level analysis is emphasized. This article goes beyond discussion of the minimum, “do no harm” standard that researchers should meet in attending to diversity and inclusion in research and urges the pursuit of equity, anti-racism, and justice toward dismantling those structures that perpetuate violence in its many forms. Researchers are encouraged to ask themselves: Where would I situate my research? Is it racist, not racist, or anti-racist? Not all IPV research has the goal of dismantling inequities, but we should aspire that it do so.
How Accurate Are Accuracy-Nudge Interventions? A Preregistered Direct Replication of Pennycook et al. (2020)
Authors: Roozenbeek Jon , Freeman Alexandra L. J. , van der Linden Sander
Published: June 2021

As part of the Systematizing Confidence in Open Research and Evidence (SCORE) program, the present study consisted of a two-stage replication test of a central finding by Pennycook et al. (2020), namely that asking people to think about the accuracy of a single headline improves “truth discernment” of intentions to share news headlines about COVID-19. The first stage of the replication test ( n = 701) was unsuccessful ( p = .67). After collecting a second round of data (additional n = 882, pooled N = 1,583), we found a small but significant interaction between treatment condition and truth discernment (uncorrected p = .017; treatment: d = 0.14, control: d = 0.10). As in the target study, perceived headline accuracy correlated with treatment impact, so that treatment-group participants were less willing to share headlines that were perceived as less accurate. We discuss potential explanations for these findings and an unreported change in the hypothesis (but not the analysis plan) from the preregistration in the original study.

Published: June 2021

Objective:

Faced with the frustration of chronic discomfort and restricted mobility due to osteoarthritis (OA), many individuals have turned to acupuncture for relief. However, the efficacy of acupuncture for OA is uncertain, as much of the evidence is inconclusive. The purpose of this study was to evaluate electroacupuncture (EA) in a rodent model of OA such that conclusions regarding its effectiveness for symptom or disease modification could be drawn.

Methods:

Ten 12-month-old male Hartley guinea pigs—which characteristically have moderate to advanced OA at this age—were randomly assigned to receive EA for knee OA (n = 5) or anesthesia only (control group, n = 5). Treatments were performed three times weekly for 3 weeks, followed by euthanasia 2 weeks later. Gait analysis and enclosure monitoring were performed weekly to evaluate changes in movement. Serum was collected for inflammatory biomarker testing. Knee joints were collected for histology and gene expression.

Results:

Animals receiving EA had significantly greater changes in movement parameters compared to those receiving anesthesia only. There was a tendency toward decreased serum protein concentrations of complement component 3 (C3) in the EA group compared to the control group. Structural and antioxidant gene transcripts in articular cartilage were increased by EA. There was no significant difference in total joint histology scores between groups.

Conclusion:

This study provides evidence that EA has a positive effect on symptom, but not disease, modification in a rodent model of OA. Further investigations into mechanistic pathways that may explain the efficacy of EA in this animal model are needed.
A Prospective Cohort Study Comparing Functional Outcomes of Primary and Revision Ankle Replacements
Authors: Jennison Toby , King Andrew , Hutton Christopher , Sharpe Ian
Published: June 2021

Background:

The number of ankle and revision ankle replacements performed is increasing. There is limited research into functional outcomes, especially in revision ankle replacements. The primary aim of this cohort study was to determine the functional improvements following primary and revision ankle replacements and compare which gave the greatest improvement in functional scores.

Methods:

A single-center prospective cohort study was undertaken between 2015 and 2018. All patients were followed up for a minimum of 2 years. Patients undertook a preoperative and 2-year Manchester Oxford Foot Questionnaire (MoxFQ) score. The Mann Whitney test was undertaken.

Results:

A total of 33 primary and 23 revision ankle replacements were performed between 2015 and 2018. The mean age was 69.3 years for primary replacements and 64.7 years for revision replacements. All primary replacements were the Infinity ankle replacement. Revision replacements were either the Inbone II or Invision. The indication for revision was 9 aseptic loosening, 6 infections, 5 cysts, and 3 malposition. Seventeen were performed as a single stage and 6 as a 2-stage revision. The overall MoxFQ improved by a mean of 48.8 for primaries and 20.2 for revisions ( P = .024). The walking/standing domain improved by 57.5 for primaries and 22.5 for revisions ( P = .016), the pain score improved by 43.0 and 32.3 ( P = .009), and the social interaction improved by 40.0 and 11.7 ( P = .128).

Conclusion:

Both primary and revision ankle replacements result in improved functional scores. In this relatively small cohort with the implants used, primary ankle replacements though have a significantly greater improvement in functional scores compared to revision ankle replacements.

Assessment of Hindfoot Alignment Comparing Weightbearing Radiography to Weightbearing Computed Tomography
Authors: Arena Christopher B. , Sripanich Yantarat , Leake Richard , Saltzman Charles L. , Barg Alexej
Published: June 2021

Background:

Hindfoot alignment view (HAV) radiographs are widely utilized for 2-dimensional (2D) radiographic assessment of hindfoot alignment; however, the development of weightbearing computed tomography (WBCT) may provide more accurate methods of quantifying 3-dimensional (3D) hindfoot alignment. The aim of this study was to compare the 2D calcaneal moment arm measurements on HAV radiographs with WBCT.

Methods:

This retrospective cohort study included 375 consecutive patients with both HAV radiographs and WBCT imaging. Measurement of the 2D hindfoot alignment moment arm was compared between both imaging modalities. The potential confounding influence of valgus/varus/neutral alignment, presence of hardware, and motion artifact were further analyzed.

Results:

The intraclass correlation coefficients (ICCs) of interobserver and intraobserver reliability for measurements with both imaging modalities were excellent. Both modalities were highly correlated (Spearman coefficient, 0.930; P < .001). HAV radiographs exhibited a mean calcaneal moment arm difference of 3.9 mm in the varus direction compared with WBCT (95% CI, –4.9 to 12.8). The difference of hindfoot alignment between both modalities was comparable in subgroups with neutral/valgus/varus alignment, presence of hardware, and motion artifact.

Conclusion:

Both HAV radiographs and WBCT are highly reliable and highly correlated imaging methods for assessing hindfoot alignment. Measurements were not influenced by severe malalignment, the presence of hardware, or motion artifact on WBCT. On average, HAV radiographs overestimated 3.9 mm of varus alignment as compared with WBCT.

Level of Evidence:

Level III, retrospective comparative study.
Progress in oncology biosimilars till 2020: Scrutinizing comparative studies of biosimilar monoclonal antibodies
Authors: Safdar Aqsa , Butt Muhammad Hammad , Ahmad Abrar , Zaman Muhammad
Published: June 2021

Stupendous elevation in the healthcare costs has followed with the inception of the current unconventional options of treatment available for cancer patients. There is a dire need of innovative financing approaches to lessen the financial load on healthcare system. Biosimilars are biological drugs consisting of an active ingredient from a reference biological drug that has a great potential of relieving financial load. Strict requirements from regulatory point of view are required as biosimilars are exceedingly similar to but not identical to the reference product. This provides with a certainty that no consequential differences from clinical point of view as compared to the respective biologics exists with regards to efficacy, safety and purity. Safety and effectiveness of biosimilars have been disclosed since more than 10 years of affirmations. However, there is a need to educate the healthcare professionals to abolish potential misconceptions and coalesce biosimilars into regular clinical practice. The present review focuses on providing an overview of regulatory aspects and requirements for biosimilars, the main challenges in the selection and development of biosimilars and the economic impact and financial savings observed in recent studies carried out in different parts of the world. In addition, we have discussed the different successful comparative studies which have been done in different parts of the world to depict the biosimilarity for monoclonal antibodies such as bevacizumab, trastuzumab and rituximab.

Published: June 2021

Purpose:

Accumulating evidence suggests that neuroinflammation and immune response are part of the sequence of pathological events leading to optic nerve damage in glaucoma. Changes in tissue temperature due to inflammation can be measured by thermographic imaging. We investigated the ocular surface temperature (OST) profile of glaucomatous eyes to better understand the pathophysiology of these conditions.

Methods:

Subjects diagnosed with glaucoma (primary open angle glaucoma [POAG] or pseudo exfoliation glaucoma [PXFG]) treated at the Sam Rothberg Glaucoma Center (11/2019–11/2020.) were recruited. Healthy subjects with no ocular disease served as controls. The Therm-App thermal imaging camera was used for OST acquisition. Room and body temperatures were recorded, and the mean temperatures of the medial cantus, lateral cantus, and cornea were calculated with image processing software.

Results:

Thermographic images were obtained from 52 subjects (52 eyes: 25 POAG and 27 PXFG) and 66 controls (66 eyes). Eyes with glaucoma had a significantly higher OST compared to controls (mean 0.9 ± 0.3°C, p < 0.005). The difference between the two groups remained significant after adjustment for age, sex, intraocular pressure (IOP) and room and body temperatures. Lens status and topical IOP-lowering medication did not significantly affect OST. A subgroup analysis revealed that the OST was higher among eyes with POAG compared to eyes with PXFG, but not significantly.

Conclusions:

Differences in the OST between glaucomatous and normal eyes strengthens current thinking that inflammation affects the pathophysiology of glaucoma. Longitudinal studies are warranted to establish the prognostic value of thermographic evaluations in these patients.
Bodies under Pressure: Experiencing Waiting Time in Basic Health Care Facilities (Morocco)
Authors: Tantchou Josiane Carine
Published: June 2021

This article addresses access to basic health care facilities in Morocco, by emphasizing the issue of accommodation (Penchansky & Thomas, 1981). This article is based on data collected over three years spent in Rabat, Morocco, for fieldwork. The first year focused on hypertension. Research authorization was required for this research, which was obtained from the Ministry of Health. Research tools consisted of observations, in-depth interviews, and focus group discussions.

I argue that waiting is not a passive experience or state. It is experienced with and through a mindful body (Scheper-Hughes & Lock, 1987), as an active and dynamic process that happens in a waiting room. The waiting room is conceptualized as a sphere of coexisting heterogeneity (Massey, 2005), allowing the concomitant presence of the body-self, social body, and the body politic, equivalent to body-inside and body-outside, respectively. By relating multiplicity and heterogeneity to time—biomedicine’s time, different from patients’ time, but also from the body’s time or somatic time (Limor Meoded, 2018)—, I argue that the space of the waiting room brings these various temporalities together, commanding new configurations and processes (Massey, 2005). The dynamic process of waiting is embodied; it can burst out in the form of tension, when the concomitant presence of distinct trajectories, bodies, and temporalities inside the waiting room, sometimes generate violence (verbal and symbolic). Allowing this heterogeneity to coexist smoothly is the challenge of hospital architecture and its analysis from a phenomenological perspective will bring rich data to explore and extend the project of an anthropogeography of emotions and perception.
Behavior analytic interventions for children with autism: Policy and practice in the United Kingdom and China
Authors: Liao Yini , Dillenburger Karola , Hu Xiaoyi
Published: June 2021

This study explored the experiences of professionals and parents from the United Kingdom and China of autism-relevant policies, school involvement, and applied behavior analysis-based interventions. Semistructured interviews involving 36 parents and professionals and direct behavioral observations were carried out of five parents and three professionals. Results found: (1) a lack of autism support and applied behavior analysis-related services in both countries; (2) applied behavior analysis-based intervention was not as widely endorsed by healthcare or educational systems in the United Kingdom; Chinese parents faced challenges around inclusive education and accessing high-quality services and there was a social stigma attached to autism; (3) a limited awareness and application of early intensive behavior intervention in both regions; and (4) intervention fidelity with regards to the practice of one particular applied behavior analysis-based intervention, discrete trial teaching, was similar and increased with ongoing training. Professional and parental experiences were discussed in the context of policy and educational involvement. This study illustrates the need to support children with autism and to consider regional adaptations of evidence-based practice of behavior analysis for the affected population.

Lay abstract

The prevalence of autism is increasing, and the development of these children and the lived experience of their families have become a global concern. Applied behavioral analytic intervention is proved to be effective in improving their cognitive abilities, language skills, and social and emotional skills, but the service delivery between developed and developing countries is different. A qualitative study was conducted to explore personal experiences with actual practice fidelity of behavior analytic services for children with autism in a Western developed country (United Kingdom) and an Eastern developing country (China). The study found: (1) a lack of support for autism and behavioral analytic services in both countries; (2) applied behavioral analytic intervention was not as widely endorsed by healthcare or educational systems in the United Kingdom; Chinese parents faced challenges around inclusive education and accessing high-quality services and there was a social stigma attached to autism; (3) a limited awareness and application of early intensive behavior intervention in both regions; and (4) intervention fidelity with regards to the practice of one particular aspect of behavioral analytic interventions was similar and increased with ongoing training. This study emphasizes the need to support children with autism, and to consider regional adaptations of evidence-based practice of behavior analytic interventions for the affected population.
A multi-objective optimization algorithm for Bouc–Wen–Baber–Noori model to identify reinforced concrete columns failing in different modes
Authors: Li Zele , Noori Mohammad , Zhao Ying , Wan Chunfeng , Feng Decheng , Altabey Wael A
Published: June 2021

Concrete columns are the most important load-bearing components in civil structures. The potential damage in reinforced concrete (RC) columns could be categorized into three different failure modes: flexural shear (FS) failure, flexural-failure (FF), and shear failure (SF). The corresponding hysteresis loops for each mode differ significantly. Therefore, a multi-parameter hysteretic restoring force model is needed to describe the hysteretic energy dissipation phenomenon and behavior. Identification of the optimal parameter values of a multi-parameter hysteresis model of RC columns under different failure modes is essential in the evaluation of structural inelastic seismic performance. In this paper, a multi-objective optimization algorithm called NSGA-II is employed to identify the parameters of Bouc–Wen–Baber–Noori model (BWBN) hysteresis model, this model has been used for describing the response and modelling restoring force behavior in several structural and mechanical engineering systems, that can fully describe the hysteretic restoring force characteristics of RC columns. An objective function for the restoring force is proposed to identify the parameters of BWBN model. In order to ensure the accuracy of identification, based on the sensitivity analysis, the parameters distribution law of RC columns in different failure modes is obtained. Furthermore, the reference values under different failure modes are proposed. The results presented in this paper will significantly reduce the calculation of subsequent identification. Twelve groups of experimental data are randomly selected to verify the feasibility of the above algorithm. It is demonstrated that using the multi-objective optimization algorithm leads to better identification accuracy with minimum prior experience. Performance of the algorithm is verified using simulated and experimental data. The experimental data of the RC columns were collected from the database of the Pacific Earthquake Engineering Research Center.
Rethinking Moving beyond Deterrence: A Partial Replication Study
Authors: Alimi Eitan , Maney Gregory
Published: June 2021

We assess Dugan and Chenoweth’s Rational Choice-based argument regarding moderating effects of indiscriminate conciliatory state actions on levels of terrorist attacks in Israel-Palestine, utilizing data drawn primarily from declassified security records on Israeli state actions during the First Intifada (1987–1992). This type of data source, we argue, contains a more accurate ratio of conciliatory to repressive actions than Dugan and Chenoweth’s media-based data, given state authorities’ attempts at concealing repressive actions while publicizing conciliatory actions during times of intense conflict. We discuss differences in results—including, most centrally, no support for the hypothesized effect of conciliatory state actions—highlighting the theoretical payoffs of examining the Political Process–related factor of varying levels of state control over the political environment.
Cultural Values and Beliefs of Selected Local Communities in Botswana: Implications for Human Subject Research Ethics Practice
Authors: Koloi-Keaikitse Setlhomo , Geller Gail , Jankie Dudu , Ali Joseph
Published: June 2021

Calls have been made for researchers prospectively and continuously to engage study communities. If done, this typically occurs through a specific research study or collaboration. Rarely are community mores examined in-depth to understand implications for research ethics policy processes. We describe a qualitative study designed to understand local community values, beliefs, and practices that relate to research ethics in Botswana and explore how communities would want their interests represented. Through focus group discussions across two different selected ethnic communities and in-depth interviews with paramount chiefs, we highlight a range of community values and expectations that represent concrete behavioral representations of respect and trustworthiness. Communities are willing to engage in the process of enhancing research and research ethics policies and procedures. We invite future research and training that seek to connect local conceptualizations of substantive and procedural aspects of research ethics.
Transbrachial and transfemoral approaches combined with visceral protection for the treatment of juxtarenal aortoiliac occlusive disease: Technical issues and clinical outcomes
Authors: Gao Peixian , Li Changliang , Wu Xuejun , Li Gang , Dong Dianning , Qi Jiaxin
Published: June 2021

Purpose

To evaluate the safety and efficacy of transbrachial and transfemoral approaches combined with visceral protection for the endovascular treatment of juxtarenal aortoiliac occlusive disease (AIOD) over an average 19-month follow-up period.

Methods

In this retrospective analysis, all patients with juxtarenal AIOD at a single institution were reviewed from June 2015 to January 2020. Patient characteristics, angiographic results, and follow-up outcomes were retrospectively recorded. The indications for treatment were critical limb threatening ischemia in 12 patients and bilateral claudication in five patients. Percutaneous access via the left brachial artery was first obtained to recanalize the infrarenal occluded lesions. After that, femoral accesses were achieved. A 4-Fr catheter, a 4 mm balloon, or a 6-Fr 90-cm-long sheath was used to complete visceral artery protection.

Results

A total of 17 juxtarenal AIOD patients (14 males; mean age, 63.4 ± 8.1 years) underwent endovascular treatment. The technical success rate was 100%. Complete reconstruction was achieved in 15 (88.2%) patients. The infrarenal aorta was reconstructed with kissing covered stent grafts ( n = 7), kissing bare-metal stents ( n = 2), covered stent grafts ( n = 2), bare-metal stents ( n = 1), or the off-label use of iliac limb stent grafts ( n = 5). Renal embolization was found in 3 (17.6%) patients during intraoperative angiography. There was 1 (5.9%) case of distal runoff embolization after CDT and 1 (5.9%) case of left iliac artery rupture. One (5.9%) death occurred due to acute myocardial infarction 20 days after the operation. The average follow-up period was 19.3 ± 16.7 months (range, 1–54 months) in the remaining 16 cases. The renal artery patency rate was 100%. The estimated cumulative primary patency rates were 92.3% at 12 months and 59.3% at 36 months according to the Kaplan–Meier method.

Conclusions

Transbrachial and transfemoral approaches combined with visceral protection offer a safe and effective alternative to open revascularization for the endovascular treatment of juxtarenal AIOD.

Authors: Guggisberg Marika , Haldane Hillary J , Lowik Vicki , Taylor Annabel , Mackay Bethany , Signal Tania
Published: June 2021

Background:

University students have been recognized as particularly being vulnerable to sexual victimization.

Purpose:

With little research to date, and acknowledgement for the need of a better understanding of sexual violence, our study analysed the CQUniversity Sexual Assault Survey’s qualitative responses. An open-ended qualitative question allowed students to provide information anonymously.

Methods:

A total of 109 participants contributed responses with 17 respondents commenting on the fact that the survey omitted to ask about child sexual abuse prior to the cut-off age of 12 years.

Results:

University students revealed unexpected disclosures of prepubescent child sexual abuse victimization and ongoing sexual victimization into adulthood. Furthermore, students’ comments indicated negative impacts including distress, mental health and substance use problems, distrust, and interpersonal difficulties. Strong feelings about ‘silencing’ prepubescent child sexual abuse in university surveys were expressed with a request that questions about child sexual abuse prior to the age of 12 years be included.

Conclusion:

Our study found that child sexual abuse victimization is important to students. Recommendations indicate the need for future research about sexual violence among university students without age restrictions to gain a better understanding about the impact of trauma including revictimization experiences.

Published: June 2021

Organizational culture is crucial for all living institutional structures and has become a critical research topic. Although different variables have been investigated in the literature as predictors of organizational culture, to our knowledge, the role of social values and life skills as mediators hasn’t been investigated before. This study, therefore, aims to investigate the role of social values and life skills as mediators of organizational culture. The hypotheses of the research were tested in the context of this research aim. The present study, which is in the relational survey model, included 370 participants consisting of teachers and school leaders working in 22 different educational institutions. The findings showed that teachers and school leaders had high levels of organizational culture, social values, and life skills. The relationship of organizational culture with social values and life skills is meaningful and high. Also, the findings indicate a partial effect on mediating organizational culture between social values and life skills.
Engaging Startup Employees via Charismatic Leadership Communication: The Importance of Communicating “Vision, Passion, and Care”

Published: June 2021

This study explores how startup leadership communication influences employee outcomes. Specifically, drawing upon interdisciplinary insight from public relations, leadership, and managerial psychology, this study tests how startup CEO charismatic leadership communication, which is characterized by envisioning, energizing, and enabling behaviors help nurture quality employee relationships with the startup and engage startup employees. Employees’ psychological need satisfaction was examined as a potential mediator in this process. This study sets its context in mainland China where startups are rapidly developing alongside increased governmental policy and financial support encouraging innovation. Through a quantitative survey of 1,027 Chinese startup employees from a variety of industries in China, this study showed that startup leader charismatic communication meets employee psychological need for autonomy, competence, and relatedness, which ultimately contributes to quality employee-startup relationships and employee engagement. This study provides important theoretical implications for public relations, internal communication and management scholars and offer practical insights for entrepreneurs and startup leaders on how to utilize strategic communication to engage startup employees.
Visualizing Injustice or Reifying Racism? Images in the Digital Media Coverage of the Killing of Michael Brown
Authors: Phelps Michelle S. , Hamilton Amber M.
Published: June 2021

The explosion of Black Lives Matter protests in the mid-2010s rendered visible state violence against Black Americans, producing a barrage of images and videos of lethal police violence and the protests that followed. These images served as a powerful site of contestation about the meaning of race and racism in the United States for both movement supporters and critics. We examine these dynamics through the lens of media coverage of the pivotal 2014 killing of Michael Brown by police officer Darren Wilson and the protests that followed in Ferguson, MO. Drawing from literatures on race, visuality, and media studies, we explore how media outlets pictured the killing of Michael Brown and the protests in Ferguson, either resisting or reproducing the white racial frame through the selection of images in their coverage. We analyze the images in digital media coverage across nine ideologically diverse media outlets in the month after Brown’s death and the month following the non-indictment of Officer Wilson. Across 1,303 articles, we show that most sites did not center images of violence against Brown, preferring instead images of Brown’s life and, more commonly, protesters and law enforcement. While we found few consistent differences in image categories preferred across outlets’ ideological profiles, the specific content and tone of these images starkly diverged, with liberal sites choosing humanizing images of Brown and protesters and conservative sites favoring criminalizing images. We conclude by considering the role media images play in mediating perceptions of race and racism.

NaY zeolite was synthesized from kaolin/dimethyl sulfoxide (DMSO) intercalation composites using an in situ crystallization technique. The effects of the intercalation ratios and the amounts of the kaolin/DMSO intercalation composite on the synthesis of an NaY zeolite molecular sieve were studied. The samples were characterized by X-ray diffraction, Fourier-transform infrared spectroscopy, differential thermal analysis, N2 adsorption–desorption and scanning electron microscopy. In the in situ synthesis system, when the kaolin/DMSO intercalation composite was added, pure NaY zeolite was formed. By increasing the amount of kaolin/DMSO intercalation composite added, the crystallinity of the samples increased, and after reaching the maximum amount of kaolin/DMSO intercalation composite added, the crystallinity decreased with further increases of the amount of kaolin/DMSO intercalation composite added. To higher intercalation ratio, the crystallinity can be greatly improved at the lower addition content. At an intercalation ratio of 84%, the added amount of kaolin/DMSO intercalation composite was 2.5% and the crystallinity of the NaY zeolite molecular sieve reached a maximum value of 45%. At intercalation ratios of 55% and 22%, the amount of kaolin/DMSO intercalation composite added was 15% and the crystallinities of the NaY zeolite molecular sieves were 44% and 47%, respectively. The NaY zeolite has good thermal stability and a particle diameter of ~0.5 μm. The Brunauer–Emmett–Teller (BET) specific surface area and pore volume of the sample were 519 m2 g–1 and 0.355 cm3 g–1, respectively.
