Published: December 2021

The underlying mechanism(s) of the Bilateral Deficit (BLD) phenomenon is without consensus. Methodological inconsistencies across prior works may be an important source of equivocal results and interpretations. Based on repeatability problems with the BLD measure and maximal force definition, the presence or absence of the BLD phenomenon is altered, shifting conclusions of its mechanistic cause. Our purpose in this study was to examine methodological inconsistencies in applying the BLD measure to establish optimal methods for evaluating the underlying mechanism. Eleven healthy participants engaged in one familiarity and five test sessions, completing bilateral and unilateral elbow maximal voluntary isometric contractions. We defined maximal force by averaged and absolute peak and plateau values. BLD was evident if the bilateral index (BI), the ratio of the bilateral over summed unilateral forces, was statistically different from zero. We addressed interclass correlations (ICC), Chronbach’s α, standard error of the mean, and minimal detectable change between and within sessions for all force measures and BI. We evaluated all combinations of sessions (i.e., 1–2, 3–5, 5–6) and maximal forces to establish the optimal number of sessions to achieve reliability. BLD was present for test sessions, but not for familiarization. All measures of maximal force were highly reliable between and within sessions (ICC(2,1) ≥ .895). BI was only considered significantly reliable in sessions 3–5 ( p < .027), defined by absolute and average plateau forces, but reliability was still quantifiably poor (absolute: ICC(2,1) = .392; average: ICC(2,1) = .375). These results demonstrate that high force reliability within and between sessions does not translate to stable and reliable BI, potentially exposing the lack of any defined BLD mechanism.

Published: December 2021

As knowledge and attitude towards performing basic life support and using an automated external defibrillator (BLS and AED) contribute equally to improving survival after out-of-hospital cardiac arrest, we aimed to develop a measuring instrument for a validated assessment of schoolchildrens' attitude towards BLS and AED. The objective was to identify, measure, and address pertinent attitude dimensions that influence the intention to actually perform BLS and AED. We conducted a BLS and AED course for seventh and ninth grade students. Students fulfilled pre- and post-course questionnaires on attitude and intention to perform BLS and AED. The measuring instrument was developed with the use of exploratory factor analysis with application of principal component analysis and confirmatory factor analysis with application of structural equation modeling. Measurement invariance across different groups (gender, grades, previous courses) was tested with Wilcoxon signed ranks test and Mann–Whitney U test. Differences in attitude pre- and post-course were evaluated by application of Mann–Whitney U test. The final attitude model consisted of 3 behavioral constructs (self-confidence, positive motivation, and amotivation). Self-confidence was the major construct directly affecting the intention to act. Positive motivation had a negligible direct effect on intention but correlated strongly with self-confidence. The effect of attitude on the intention to help is therefore less complicated than was expected, which relieves the non-professional educators of having to know the specifics of the different behavioral constructs.

Published: December 2021

To examine whether rates of 30-day readmission after acute ischemic stroke changed differentially between Medicaid expansion and non-expansion states, and whether race/ethnicity moderated this change, we conducted a difference-in-differences analysis using 6 state inpatient databases (AR, FL, GA, MD, NM, and WA) from the Healthcare Cost and Utilization Project. Analysis included all patients aged 19-64 hospitalized in 2012–2015 with a principal diagnosis of ischemic stroke and a primary payer of Medicaid, self-pay, or no charge, who resided in the state where admitted and were discharged alive (N=28 330). No association was detected between Medicaid expansion and readmission overall, but there was evidence of moderation by race/ethnicity. The predicted probability of all-cause readmission among non-Hispanic White patients rose an estimated 2.6 percentage points (or 39%) in expansion states but not in non-expansion states, whereas it increased by 1.5 percentage points (or 23%) for non-White and Hispanic patients in non-expansion states. Therefore, Medicaid expansion was associated with a rise in readmission probability that was 4.0 percentage points higher for non-Hispanic Whites compared to other racial/ethnic groups, after adjustment for covariates. Similar trends were observed when unplanned and potentially preventable readmissions were isolated. Among low-income stroke survivors, we found evidence that 2 years of Medicaid expansion promoted rehospitalization, but only for White patients. Future studies should verify these findings over a longer follow-up period.
Small-Area Analyses Using Public American Community Survey Data: A Tree-Based Spatial Microsimulation Technique
Authors: Graetz Nick , Ummel Kevin , Aldana Cohen Daniel
Published: December 2021

Quantitative sociologists and social policymakers are increasingly interested in local context. Some city-specific studies have developed new primary data collection efforts to analyze inequality at the neighborhood level, but methods from spatial microsimulation have yet to be broadly used in sociology to take better advantage of existing public data sets. The American Community Survey (ACS) is the largest household survey in the United States and indispensable for detailed analysis of specific places and populations. The authors propose a technique, tree-based spatial microsimulation, to produce “small-area” (census-tract) estimates of any person- or household-level phenomenon that can be derived from ACS microdata variables. The approach is straightforward and computationally efficient, based only on publicly available data, and it provides more reliable estimates than do prevailing methods of microsimulation. The authors demonstrate the technique’s capabilities by producing tract-level estimates, stratified by race/ethnicity, of (1) the proportion of people in the census-tract population who have children and work in an essential occupation and (2) the proportion of people in the census-tract population living below the federal poverty threshold and in a household that spends greater than 50 percent of monthly income on rent or owner costs. These examples are relevant to understanding the sociospatial inequalities dramatized by the coronavirus disease 2019 pandemic. The authors discuss potential extensions of the technique to derive small-area estimates of variables observed in surveys other than the ACS.
On Sharing the Wealth Philippine Style
Authors: Douglas Donald E.
Published: December 2021

It is paradoxical that those most highly motivated to give, with regard to their time and talents, e. g. foreign missionaries, experience such inner wrenching when it comes to sharing their personal wealth with others. Most often this tension does not occur because of blatant unwillingness to share, but simply because missionaries, particularly the newly arrived, are not aware of distinctive Philippine patterns of sharing. Fulfilling one's obligation to share, in socially acceptable ways, may help to alleviate personal tension and at the same time enhance the prospect of vital communication with individuals in the Philippines.
Classification of Au Myths
Authors: Scorza David
Published: December 2021

Folklore among the Au of Papua New Guinea takes three forms: Tipiitim Tipiir, tales told the ancestors by the spirits; Tipiitim Herwe, tales invented by the ancestors; and Him, tales invented by the older men. The first are basically etiological, the second provide emotional release and entertainment, and the third show attempts to cope with the cultural flux which followed the arrival of Europeans. Certain Scriptural parallels are explored, with their implications for crosscultural communication of the gospel.
The Importance of Similarity: How Gender Congruence Matters for the Impact of Leadership Training
Authors: Fjendbo Trine H. , Jacobsen Christian B. , An Seung-Ho
Published: December 2021

Leadership training is key to promoting more active leadership, but the effects of leadership training can depend on the gender context. Gender congruence between manager and employee can affect how the manager employs leadership behaviors adapted from training and how employees perceive leadership behavior. Quantitative data on 474 managers’ 4,833 employees before and after a large-scale field experiment with leadership training enable us to examine changes in employee-perceived leadership following training. The results show that gender congruence between manager and employee is associated with stronger leadership training effects on employee-perceived leadership behaviors. Female gender congruence shows the most pronounced effects.
Do Business-Backed Think Tanks Represent Class Interests? The Co-evolution of Policy Learning and Economic Elites in the Canadian Knowledge Regime
Authors: Landry Julien
Published: December 2021

Business-backed think tanks are often presented as representing the interests of economic elites. This article provides a more nuanced argument by using field theory to present the co-evolutionary dynamics between economic elites and other social forces. Three Canadian think tanks are examined to illustrate how different social forces can converge around business-backed think tanks, and how governance contexts and institutions shape these relationships. The paper also reflects on the kinds of learning these think tanks can enable depending on the kinds of actors that converge around them and on the forms of power that these actors represent.
Auditor Choice and the Informativeness of 10-K Reports
Authors: Hrazdil Karel , Simunic Dan A. , Suwanyangyuan Nattavut
Published: December 2021

This study provides new evidence on the influential role of external auditors in enhancing the informativeness of form 10-K annual reports to shareholders. Specifically, we find that the client’s choice of a Big 4 auditor (PwC, EY, KPMG, and Deloitte) versus a non-Big 4 auditor contributes to cross-sectional variations in 10-K disclosure volume. We also document that the benefit of enhanced disclosures provided by Big 4 auditors is more pronounced for audit clients with poorer accrual quality and those with higher information asymmetry. Furthermore, we introduce the portion of 10-K length unexplained by operating complexity and observable client characteristics as a new proxy for audit firm effort. Specifically, we find that abnormally long disclosures are associated with higher audit fees and longer audit report lag, which implies that an incremental level of audit effort can be inferred from the discretionary component of 10-K disclosures. As audit effort is costly, a greater volume of 10-K disclosures can be expected to be associated with an improvement in the quality of financial reporting. Overall, our findings show that auditors play more than a simple attestation role in the financial reporting process, and that the quality of financial reporting in a company’s 10-K annual report is a joint product of the effort and decisions of both a company’s managers and its auditors.
Between the Lab and the Field: Plants and the Affective Atmospheres of Southern Science
Authors: Calkins Sandra
Published: December 2021

In view of persistent global inequalities in scientific knowledge production with clear centers and peripheries, this paper examines a lingering concern for many scientists in the Global South: why is it, at times, so hard to have scientific insights from the South recognized? This paper addresses this big question from within a long-term field immersion in a Ugandan–Australian scientific collaboration in molecular biology. I show how disciplinary hierarchies of value affect the distribution of labor between Uganda and Australia and thematize the role of place and its affective atmospheres that texture the quotidian scientific work in this project. Unsurprisingly, they tend to devalue Ugandan sites and contributions, and turn Uganda into a rather unlikely site for new insights to emerge. However, in spite of doing devalued and outsourced “menial” labor such as fieldwork, Ugandan biologists’ fieldwork involves affective encounters with their experimental banana plants that thereby become differently thinkable. The paper argues that attending to affective atmospheres that infuse research sites offers clues about scientists’ position in global hierarchies and at the same time can help make room for insights that emanate from unexpected places.
Mindful eating for overweight and obese women in Brazil: An exploratory mixed-methods pilot study
Authors: Salvo Vera , Sanudo Adriana , Kristeller Jean , Schveitzer Mariana Cabral , Martins Patricia , Favarato Maria Lucia , Demarzo Marcelo
Published: December 2021

Background: Worldwide, approximately 95% of obese people who follow diets for weight loss fail to maintain their weight loss in the long term. To fill this gap, mindfulness-based interventions, with a focus on mindful eating, are promising therapies to address this challenging public health issue. Aim: To verify the effects of the Mindfulness-Based Eating Awareness Training (MB-EAT) protocol by exploring quantitative and qualitative data collected from Brazilian women. Methods: A single-group, mixed-methods trial was conducted at a public university with adult women ( n = 34). Four MB-EAT groups were offered weekly for 2.5-h sessions over 12 weeks. Pre- and post-intervention assessments included body mass index (BMI) and self-report measures of anxiety, depression, mindfulness, self-compassion, and eating behaviour. Qualitative information was collected using focus groups in the last session of each group, including both participants and MB-EAT instructors. The qualitative data were examined using thematic analyses and empirical categories. Results: Twenty participants (58.8%) completed both pre- and post-intervention assessments, with adequate attendance (≥4 sessions). There was a significant average decrease in weight of 1.9 ± 0.6 kg from pre- to post-intervention. All participants who had scored at the risk level for eating disorders on the EAT-26 decreased their score below this risk level. Qualitative analysis identified that participants were able to engage a more compassionate perspective on themselves, as well as greater self-awareness and self-acceptance. Conclusion: The MB-EAT showed preliminary efficacy in promoting weight loss and improvements in mindfulness and eating behaviour. This intervention promoted effects beyond those expected, extending to other life contexts.

Focusing on the algorithmic character of computing machines and the thinking that these machines might express, each of the special section’s essays considers different dimensions of algorithmic thought, engaging with a diverse set of epistemological questions and issues.
‘An Epic Tale of England’: Atmospheric authentication of nationalist narratives
Authors: Shaw Robert , Richardson Michael J
Published: December 2021

Kynren is an outdoor spectacular pageantry performance which tells a tale of England, drawing on myth and history, to make several claims about Englishness and Britishness. It does so in the political wake, first, of constitutional crises in the UK centred around Brexit; and second, of debates around heritage, empire, race and nation which have been driven by responses to the Black Lives Matter movement. These themselves are manifestations of broader, global trends in which populist movements have attempted to reassert state-legitimacy through nationalism, heritage and culture. This paper explores, how Kynren affectively presents and discursively performs a narrative which puts place and landscape, and specifically the place and landscape of the peripheral region of County Durham in which it is located, at the heart of nation. We argue that the ways in which this narrative is authenticated performatively through the spectacular affective atmosphere of Kynren show how and which nationalist narratives resonate most readily in popular culture.
Stakes, positions and logics: An institutional field analysis of cross-border health IT policy
Authors: Currie Wendy L , Seddon Jonathan JJM
Published: December 2021

The concepts field and habitus are used widely and variably in institutional theory. The intellectual antecedents are found in the work of the French Sociologist, Pierre Bourdieu. This study presents a field-level analysis of pan-European policy on cross-border health information technology. Using field theory and institutional theory, we situate field as a multi-level concept which extends institutional and organizational levels of analysis. Empirical data is gathered from European policymakers, health professionals and patient advocacy groups on the diffusion of supra-national health information technology across European Member States. Findings reveal four scenarios depicting field tensions, as ideological and practical imperatives of supra-national health information technology policy mis-align with Member State health systems. This study has implications for policy-makers and other stakeholders, who seek to narrow the digital divide across health fields and sub-fields.

Authors: Wang Ying , Wu Yutong , Wang Qingjing , Zhu Jiajie , Shi Wen , Han Zetao , Zhang Yanjun , Chen Keda
Published: December 2021

Objective

To evaluate the antiviral activity of the oral disinfectant povidone-iodine (PVP-I) against severe acute respiratory syndrome-coronavirus-2 (SARS-CoV2) in vitro.

Methods

The cytotoxic effects of PVP-I were determined in Vero and Calu-3 cell lines using that by Cell Counting Kit-8 assay. Viral load in the cell culture medium above infected cells was quantitated using real-time polymerase chain reaction. The cytopathic effect (CPE) and viral infective rate were observed by immunofluorescence microscopy.

Results

PVP-I at a concentration >0.5 mg/ml in contact with SARS-CoV-2 for 30 s, 1 min, 2 min and 5 min showed up to 99% viral inhibition. For in vitro testing, upon exposure for 1 min, PVP-I showed a virucidal effect. PVP-I had no cytotoxic effects at the range of concentrations tested (0.125–1 mg/ml; CC50 > 2.75 mM) in Vero and Calu-3 cells.

Conclusion

These results demonstrate that the ideal contact time was 1 min and the optimal concentration was 1 mg/ml, which provides an experimental basis for the use of oral disinfectants in dental hospitals.
Body Orientation Affects the Perceived Size of Objects
Authors: Kim John J.-J. , McManus Meaghan E. , Harris Laurence R.
Published: December 2021

Here, we investigate how body orientation relative to gravity affects the perceived size of visual targets. When in virtual reality, participants judged the size of a visual target projected at simulated distances of between 2 and 10 m and compared it to a physical reference length held in their hands while they were standing or lying prone or supine. Participants needed to make the visual size of the target 5.4% larger when supine and 10.1% larger when prone, compared to when they were in an upright position to perceive that it matched the physical reference length. Needing to make the target larger when lying compared to when standing suggests some not mutually exclusive possibilities. It may be that while tilted participants perceived the targets as smaller than when they were upright. It may be that participants perceived the targets as being closer while tilted compared to when upright. It may also be that participants perceived the physical reference length as longer while tilted. Misperceiving objects as larger and/or closer when lying may provide a survival benefit while in such a vulnerable position.
Driving Simulator Study for Evaluating the Effectiveness of Virtual Warnings to Improve the Safety of Interaction Between Cyclists and Vehicles
Authors: Calvi Alessandro , D’Amico Fabrizio , Ferrante Chiara , Bianchini Ciampoli Luca
Published: December 2021

Globally, cyclists account for 3% of all road traffic deaths, with the highest percentage occurring in Europe (8%) where the bicycle is considered a true alternative mode of transport. Among the causes of crashes are vehicles overtaking cyclists, especially on rural roads. In this study, a new application of augmented reality (AR) warnings for connected vehicles is tested by means of a driving simulator. The overall objective of the study consists in assessing the effectiveness of three proposed AR systems in improving the safety of interactions between vehicles and cyclists, especially during overtaking maneuvers. The AR systems were tested on a sample of 46 drivers and provided them with additional virtual visual information aimed at improving the driver’s risk perception and assessment of safe distance from a cyclist. The virtual warning configurations were: (i) a yellow safety zone around the cyclist; (ii) a color-changing safety zone that changes from red to green when the driver has safe lateral space to overtake the cyclist; (iii) the same color-changing security zone but with an additional acoustic warning. The AR warnings were found to be quite effective as they helped drivers overtake cyclists more safely. With AR warnings (especially with the additional audio), it was found that drivers adopted longer distances from cyclists and entered the oncoming lane less frequently, thus lowering the risk of collision with cyclists as well as the risk of head-on collision with oncoming vehicles.
Balanced Mix Design Benchmarking of Field-Produced Asphalt Mixtures in Maine, U.S.
Authors: Veeraragavan Ram Kumar , Nener-Plante Derek , Myers Leslie , Nash Casey , Tran Nam H.
Published: December 2021

Performance testing has been recognized by state highway agencies (SHAs) in the U.S. and the asphalt paving industry as an important tool to complement volumetric properties for improving asphalt pavement performance. Thus, Maine Department of Transportation (MaineDOT) initiated a research effort in 2019 to evaluate the cracking and rutting resistance of asphalt mixtures using several performance tests, including the Hamburg wheel-tracking test (HWTT), indirect tensile cracking test (IDEAL-CT), cyclic fatigue test, and stress sweep rutting (SSR) test. These tests were conducted on reheated common plant-produced asphalt mixtures, and results were analyzed to: (1) develop baseline rutting and cracking performance; (2) evaluate the effects of mixture properties on the performance test results; and (3) verify the performance enhancement from the extended use of polymer-modified asphalt binders. Several mixture properties, such as nominal maximum aggregate size (NMAS), binder performance grade (PG), binder content (Pb), and reclaimed asphalt pavement (RAP) %, were found to have statistically significant effects on the mixture rutting and cracking resistance, especially the HWTT and IDEAL-CT results. Based on the proposed criteria for rutting strain index (RSI) and apparent damage capacity (Sapp), the asphalt mixtures tested would provide satisfactory rutting performance under heavy traffic, and satisfactory cracking performance under standard traffic. In addition, based on the IDEAL-CT benchmarking results, mixtures with polymer-modified binder and/or smaller NMAS were found to have higher cracking tolerance index (CTindex) results. The information from the research effort will help MaineDOT to achieve its goal to move beyond sole use of volumetric properties for asphalt mixture design and acceptance with the implementation of balanced mix design (BMD) for improving the field performance of asphalt pavements.
Depression Symptoms, Mattering, and Anti-mattering: Longitudinal Associations in Young Adulthood
Authors: Krygsman Amanda , Farrell Ann H. , Brittain Heather , Vaillancourt Tracy
Published: December 2021

We examined the dynamic interplay of depression symptoms, mattering (i.e., self-evaluation of importance or significance to others), and anti-mattering across four years of development in young adulthood (age 20–23; N = 452) using a cross-lagged panel model (CLPM). Support for a transactional model between anti-mattering and depression symptoms was found. Specifically, anti-mattering positively predicted later depression symptoms and depression symptoms consistently predicted later anti-mattering. Depression symptoms also shared a negative association with later mattering but not the reverse, supporting a symptoms-driven model of depression symptoms and mattering. Auto-regressive paths, residual covariances, and cross-lagged paths were invariant over time. Accounting for gender, household income, parental education, and fear of COVID-19 as covariates did not change the results. The stability of mattering and anti-mattering suggest careful consideration of how to effectively change these patterns. The implications for assessment and intervention on mattering or anti-mattering in the prevention and treatment of depression are discussed.
Young People’s Coping Strategies When Dealing With Their Own and a Friend’s Symptoms of Poor Mental Health: A Qualitative Study
Authors: Pimenta Sofia M. , Hunter Simon C. , Rasmussen Susan , Cogan Nicola , Martin Bethany
Published: December 2021

Young people struggle to seek help for their mental health, despite having different resources available. As the coping process is very complex, and elements such as trust and availability of resources have been said to influence it, this study aimed to understand how young people cope with their own or a friend’s symptoms of poor mental health. Eleven young people (13–15 years old) were interviewed. Thematic Analysis of the interviews showed that participants reported different coping strategies for dealing with their own hypothetical symptoms and those of a friend. Participants identified the social impact of experiencing symptoms of poor mental health and choice of resources as the main factors influencing their coping strategies. For their own symptoms, young people expressed concern about being judged and that they would only disclose to someone they trust. Participants would not disclose a friend’s symptoms because they did not want to break their trust. Finally, choice of resources was mainly influenced by the severity of symptoms being experienced, especially when it comes to asking for professional help. This study contributes to a better understanding of the different ways in which young people cope with their own symptoms and symptoms experienced by a friend.
Complications Associated With Totally Implanted Venous Access Devices in the Arm Versus the Chest: A Short-Term Retrospective Study
Authors: Pike Samuel , Tan Kiat , Burbridge Brent
Published: December 2021

Purpose:

To retrospectively compare complications for totally implanted venous access devices (TIVADs or ports) in the arm vs. the chest. One participating institution implanted all TIVADs in the arm, whereas the other institution implanted them in the chest.

Methods:

Subjects were consecutive patients > 18 years with a device inserted between July 2017 and January 2019 at either Hospital A, where all devices were implanted in the arm, or at Hospital B, where all devices were implanted in the chest. Complications (rates/1,000 catheter-days and frequencies) were compared between the arm and chest locations.

Results:

201 arm devices (71% female, mean age 59.4 years) and 203 chest devices (66% female, mean age 61.5 years) were assessed. Overall complication rates did not differ between the arm and chest [arm: 30 complications per 56,938 catheter-days (0.530/1,000 catheter-days) vs. chest: 47 complications per 63,324 catheter-days (0.742/1,000 catheter-days), p-value 0.173]. Periprocedural complications and mechanical malfunction also did not differ. Although prophylactic antibiotic use was higher in the chest (79.3% vs. 1.50%, p-value < 0.0001), infection rates did not differ. Arm venous thrombosis was significantly higher in the arm cohort (0.205 vs. 0.017/1,000 catheter-days, p-value 0.003) and pulmonary thromboembolism in the chest cohort (0.269 vs 0.056/1,000 catheter-days, p-value 0.002).

Conclusions:

While arm venous thrombosis was higher in the arm and pulmonary thromboembolism in the chest cohort, other complications were similar. Antibiotic use was more frequent in the chest cohort, while infection rates remained similar in both cohorts.

Published: December 2021

Purpose: To gauge the level of interest in breast imaging (BI) and determine factors impacting trainees’ decision to pursue this subspecialty. Methods: Canadian radiology residents and medical students were surveyed from November 2020 to February 2021. Training level, actual vs preferred timing of breast rotations, fellowship choices, perceptions of BI, and how artificial intelligence (AI) will impact BI were collected. Chi-square, Fisher’s exact tests and univariate logistic regression were performed to determine the impact of trainees’ perceptions on interest in pursuing BI/women’s imaging (WI) fellowships. Results: 157 responses from 80 radiology residents and 77 medical students were collected. The top 3 fellowship subspecialties desired by residents were BI/WI (36%), abdominal imaging (35%), and interventional radiology (25%). Twenty-five percent of the medical students were unsure due to lack of exposure. The most common reason that trainees found BI unappealing was repetitiveness (20%), which was associated with lack of interest in BI/WI fellowships (OR = 3.9, 95% CI: 1.6-9.5, P = .002). The most common reason residents found BI appealing was procedures (59%), which was associated with interest in BI/WI fellowships (OR, 3.2, 95% CI, 1.2-8.6, P = .02). Forty percent of residents reported an earlier start of their first breast rotation (PGY1-2) would affect their fellowship choice. Conclusion: This study assessed the current level of Canadian trainees’ interest in BI and identified factors that influenced their decisions to pursue BI. Solutions for increased interest include earlier exposure to breast radiology and addressing inadequacies in residency training.

Published: December 2021

The most widely used biomaterials in the treatment of massive bone defects are allograft bone or metal implants. The current problem is that the availability of allographs is limited and metal implants are very expensive. Mass production of secretome can make bone reconstruction of massive bone defects using a scaffold more effective and efficient. This study aims to prove bone regeneration in massive bone defects using bovine hydroxyapatite reconstruction with normoxic and hypoxic secretome conditions using collagen type 1 (COL1), alkaline phosphate (ALP), osteonectin (ON), and osteopontin (OPN) parameters. This is an in vivo study using male New Zealand white rabbits aged 6–9 months. The research was carried out at the Biomaterials Center—Tissue Bank, Dr. Soetomo Hospital for the manufacturer of bovine hydroxyapatite (BHA) and secretome BM-MSC culture under normoxic and hypoxic conditions, and UNAIR Tropical Disease Institute for implantation in experimental animals. Data analysis was carried out with the one-way ANOVA statistical test and continued with the Post Hoc test LSD statistical test to determine whether or not there were significant differences between groups. There were significant differences between hypoxic to normoxic group and hypoxic to BHA group at day-30 observation using ALP, COL 1, ON, and OPN parameters. Meanwhile, there is only osteonectin parameter has significant difference at day-30 observation. At day-60 observation, only OPN parameter has significant differences between hypoxic to normoxic and hypoxic to BHA group. Between day-30 and day-60 observation, BHA and normoxic groups have a significant difference at all parameters, but in hypoxic group, there are only difference at ALP, COL 1, and ON parameters. Hypoxic condition BM-MSC secretome with BHA composite is superior and could be an option for treating bone defect.

Published: December 2021

Research has documented the experiences of transgender people in seeking employment. To date, no scholarship has explored the experiences of immigrant Latinx transgender people seeking employment in the United States. Using an intersectionality framework, the present study aimed to uncover the experiences of immigrant Latinx transgender people as they sought employment in the United States. A community sample of 18 immigrant Latinx transgender people from a large metropolitan city in Florida engaged in semi-structured interviews. Thematic analysis revealed five themes related to participants’ experiences seeking employment, including: (1) discrimination, (2) limited options, (3) positive experiences, (4) momentary de-transition, and (5) disability benefits as financial relief. Future directions such as exploring ways in which immigrant Latinx transgender people resist discrimination while seeking job opportunities are discussed. Implications for practice and advocacy such as advocating for equitable employment policies that acknowledge the intersectional experiences of this community are presented.

In this attempt, we investigate the mixed convection in Sutterby fluid flow based on boundary layer approximation. Heat transport analysis is composed of stratification and thermal radiative phenomena. The system of non-linear PDEs is transformed into coupled ODEs. Convergent series approximations are evaluated via homotopic technique. Influence of various pertinent parameters is sketched and graphically analyzed. It is found that horizontal velocity increments for higher mixed convection parameter. The radiation parameter has a similar relation with temperature whereas the stratification parameter shows opposite behavior for temperature field.
“We will make you feel safe”: Female medical staff's experiences of meeting with raped women in Sweden
Authors: Rudolfsson Lisa , Punzi Elisabeth
Published: December 2021

The focus of this study was on female emergency medical personnel's experiences of treating women who have been raped and on their own experiences of being women themselves working in this situation. We interviewed 12 female medical personnel in four focus groups of two to five participants each. The material was analyzed using inductive thematic analysis. Participants’ experiences were structured under two main themes: Prerequisites for care and Effects on oneself. As women, the participants emphasized their understanding of other women and stressed the importance of offering flexible care and taking time with each patient. They described how their work affected them personally, making them increasingly aware of men's violence against women and their need for support from their colleagues. They also discussed structural barriers to both patient care and self-care. If unaddressed, such shortcomings risk negatively affecting raped women seeking medical care and may also be detrimental to the health and well-being of the professional offering care.
“If your institution refuses to provide what you need, create it yourself”: Feminist praxis on #AcademicTwitter
Authors: Talbot Catherine V. , Pownall Madeleine
Published: December 2021

Previous research has demonstrated the impact that Twitter can have for promoting and discussing a feminist agenda. Given the gendered neoliberalism that exists within academia, tweets under the hashtag “#AcademicTwitter” may also be an important space for feminist praxis. Yet, to our knowledge, there is no empirical work analysing the function of “Academic Twitter” from a distinctly feminist perspective. Thus, we asked “How is Academic Twitter used for feminist praxis?”. We conducted a reflexive thematic analysis of 596 tweets containing the hashtag #AcademicTwitter. This generated four themes showing how Academic Twitter can be a valuable site for feminist praxis, by enabling academics to “give testimony to academia”, “access the hidden curriculum”, and engage in both “academic kindness” and “resistance and advocacy”. Despite these benefits, we also observed a tension between Academic Twitter as a site for feminist practice yet also as potentially complicit in promoting the competitiveness and overwork that pervades academia. We recommend that future feminist research interrogates the ways in which more diverse forms of feminist praxis, including more negative experiences, are negotiated on Academic Twitter.
On saline infusion, clonus, molecules and forgotten scientists: Who was Dr Julius Sander (1840–1909)?
Authors: Petroianu Georg A
Published: December 2021

Zitterbewegungen des Fusses bei Dorsalflexion (shaking movements of the foot upon dorsal flexion) were observed independently from each other and described in the same issue of a German peer reviewed journal by Carl Westphal (1833–1890) at the Charité in Berlin and by Wilhelm Erb (1840–1921) in Heidelberg. While Westphal used the term Fussphaenomen, Erb is credited with coining the term clonus for the phenomenon. Both scientists are immortalized by various eponyms acknowledging their respective contributions to science. Little is known however about Julius Sander (1840–1909), in those days resident at Charité, who noticed the phenomenon and presented it to his superiors, Wilhelm Griesinger (1817 −1868) and Westphal. In addition to such observations, Sander made original contributions in resuscitation physiology while working with Hugo Kronecker (1839–1914). With Kronecker, Sander published observations on life saving transfusions with inorganic salt solutions in dogs “ Bemerkung über lebensrettende Transfusion mit anorganischer Salzlösung bei Hunden” a very early work on isovolemic fluid resuscitation. The purpose of this communication is to highlight Sander's scientific contributions and to shed some light on his life, of which a German Lexicon stated that after 1870 no information on him can be ascertained anymore.

This study examines the influence of earnings management on the value relevance of earnings, that is, the value relevance of level and changes of earnings. The sample consists of manufacturing companies listed on the Indonesia Stock Exchange (IDX), comprising 606 observations. By using panel data regression, this study provides evidence that the level of earnings has no value relevance; conversely, changes in earnings have value relevance, indicating that earnings have less value relevance. Furthermore, the results of the relevance test of earnings value with the presence of earnings management show that the relevance of the value of the earnings level increases with the presence of earnings management; on the contrary, the relevance of earnings changes decreases with the presence of earnings management. Based on the value of earnings response coefficient, the impact of earnings management on the value relevance of level and changes of earnings appears to indicate that earnings management reduces the value relevance of earnings.
“The Menthol One Is More Friendly”: Young Singaporeans’ Perspectives on Flavored Cigarettes

Published: December 2021

Over half of the cigarettes sold in Singapore contain added flavors such as menthol. We conducted nine focus group discussions (n = 46) with young (aged 20-25) current smokers in Singapore to understand the role of flavors in smoking initiation. We found that flavors triggered the curiosity to experiment with tobacco and e-cigarette products and played an important role in the formation of early cigarette preferences. Menthol-flavored cigarettes were the most appealing to participants due to their smoothness and cooling sensation, described as pleasant against Singapore’s hot and humid climate. While some participants believed that flavored and nonflavored cigarettes were equally harmful, others believed that flavored variants had a lower nicotine content and were therefore less harmful, or that the added chemicals in flavored cigarettes could result in higher toxicant exposures. Thus, among young people in Singapore, flavors appear to play an important role in smoking initiation and there appear to be various misperceptions regarding their harmfulness.
Pesticides Use and Impaired Lung Function Among Male Agricultural Farmers in Rural Sindh, Pakistan

Published: December 2021

Use of pesticides implicated in decrement in lung function, manifested as restrictive or obstructive dysfunction or both. Using comparative cross-sectional study design, authors conducted the study to determine an association of pesticide use with impairment in lung function (restrictive/obstructive pattern of lung function) among agricultural farmers. The data were collected using modified American Thoracic Society Division of Lung Disease (ATS-DLD-78A) questionnaire and spirometer measurements. Using multinomial logistic regression, the risk of both restrictive and obstructive lung dysfunction was found to be almost twice among pesticides users with each increasing year of exposure to pesticides (1.92 and 1.95, respectively) after adjusting for other covariates. There is a need for reliable monitoring and reporting procedures along with appropriate environmental policies and regulations for handling of pesticides. Interventional studies are needed where farmers could be trained on the proper use of personal protective equipment (PPE) to limit the exposure to pesticides.

Published: December 2021

This study assessed pediatric oncology professionals’ attitudes and attendance at patient funerals.

Many professionals endorsed some level of agreement that funeral attendance respects professional boundaries. Nearly all pediatric oncology professionals (89.2%) reported attending a patient funeral at least once, a rate significantly higher than estimates in other specialties ( p <.001). Attitudes and rates of attendance were slightly higher in older physicians. While periodic funeral attendance may have been somewhat normative in this sample, further reflection and research is needed to ensure the risks and benefits of involvement in funerals and other family rituals and practices are better understood.
Individual Healthcare and Socially Constructed Identities: Cases of Women Suffering from Cardiovascular Diseases (CVDs)
Authors: Sharma Swati
Published: December 2021

Study aims at examining socio-cultural factors in the form of personal perception of the respondents towards Cardiovascular Diseases (CVDs) and the resultant impact of this perception on the CVDs management regimen of the respondents. Social construction of illness is used to investigate these factors. Entire data were collected at Superspeciality Hospital, Jammu (India) and 41 personal interviews were conducted. Field research also consisted of observations which was done by employing purposive sampling method. Results demonstrate that factors like inability to carry out household chores, financial constraints, lethargy etc. have a bearing on the care seeking behavior of the respondents. Women constantly juggle between maintaining family equilibrium and maintaining their health. Socially constructed image of a healthy woman is somewhat difficult to achieve even if technologies of the self and anatomo-politics come into play because gendered nature of healthcare in India makes it difficult for these women to prioritize their health needs.
Using Public Datasets to Understand the Psychological Correlates of Smoking, Alcohol Consumption, and Obesity: A Country-Level Analysis
Authors: Hanel Paul H. P. , da Silva Sara M. G. , Inman Richard A.
Published: December 2021

In the present research, we investigate whether cultural value orientations (CVOs) and aggregate personality traits (Big-5) predict actual levels of alcohol consumption, smoking, and obesity across 50 countries using averages derived from millions of data points. Aggregate traits explained variance above and beyond CVOs in obesity (particularly neuroticism and extraversion), while CVOs explained variance beyond aggregate traits in alcohol consumption (particularly harmony and hierarchy). Smoking was not linked to aggregated traits or CVOs. We conclude that an understanding of the cultural correlates of risky health behaviors may help inform important policies and interventions for meeting international sustainable development goals.
U.S. Public Opinion on China and the United States During the U.S.–China Trade Dispute: The Role of Audience Framing and Partisan Media Use
Authors: Ha Louisa , Ray Rik , Chen Peiqin , Guo Ke
Published: December 2021

This study examines the relationship between selective and cross-cutting/non-partisan media exposure, perceived journalism framing, and U.S. public’s perception of China and the United States during the U.S.–China trade dispute. A national survey of U.S. adult population indicated that more people perceived that the media escalated the conflict between China and the United States than promoted peace between the countries. Perceived peace journalism framing was positively related to perception of China, whereas perceived war journalism framing was positively related to perception of the United States. Partisan media use has higher influence on perception of the United States than perception of China.
