An Imagination – Procrastination Link? The Role of Efficacy Beliefs, Visual Imagery, and Affect in Academic Procrastination
Authors: Graff Meir , Barenholtz Elan
Published: April 2023

Previous studies have established that there is a relationship between efficacy beliefs and procrastination. Theory and research on motivation suggest that visual imagery (the capacity to create vivid mental images) may be implicated in this relationship and in the general tendency to procrastinate. This study’s aim was to build on prior work by examining the role of visual imagery, as well as roles of other specific personal and affective factors, in predicting academic procrastination. Self-efficacy for self regulatory behavior was observed to be the strongest predictor, predicting lower rates of academic procrastination, though this effect was significantly greater for individuals who scored higher on a measure of visual imagery. Visual imagery predicted higher levels of academic procrastination when included in a regression model with other significant factors, though this relationship did not hold for individuals who scored higher on self regulatory self-efficacy, suggesting that this self-belief may shield individuals who would otherwise be disposed to procrastination behavior. Negative affect was observed to predict higher levels of academic procrastination, contrary to a previous finding. This result highlightsthe importance of considering social contextual issues that may influence emotional states, such as those surrounding the Covid-19 epidemic, in studies of procrastination.
Exploration of geothermal resources using comprehensive electromagnetic method
Authors: Zhu Jie , Li Ping , Chen Hangbo
Published: April 2023

Geothermal resource is a kind of crucial clean, renewable energy with high potential development and application. However, it involves great exploiting risks since it buried deep beneath the crust of the Earth. The location and depth of geothermal resources can be determined using the geophysical methods. Controlled source audio-frequency magnetotellurics (CSAMT) and transient electromagnetic method (TEM) have relatively high efficiency and robustness. In this paper, a simplified geothermal system resistivity model was established, which allowed TEM and CSAMT to differentiate target faults with various characteristics (resistivity, dip angle and width). Through a comprehensive electromagnetic exploration in Huairen County, Shanxi Province, China as an example, the performance of TEM and CSAMT in determining geothermal resources was evaluated. The results showed that both methods could examine the geoelectrical structures from various perspectives, and the effectiveness of comprehensive electromagnetic method for geothermal resources was presented.

Authors: Pennini Annalisa , Caruso Rosario , Conte Gianluca , De Maria Maddalena , Nirta Lauren , Magon Arianna , Armellin Giampaolo
Published: April 2023

Although the Self-Evaluation of Resilience (SEOR) scale is a promising tool for assessing resilience in healthcare, its psychometric structure has not yet been confirmed. This study aimed to assess and validate the four-factor psychometric structure of the SEOR. Between September 2020 and January 2021, cross-sectional data were collected from randomly selected healthcare workers, managers, and administrators from a predefined network of 70 healthcare facilities in 12 Italian regions. The sample size was based on a Monte Carlo simulation using estimates from the SEOR developmental study. Two confirmatory factor models (first-order and second-order) were predefined. The responders ( n = 199, response rate, 81%) were healthcare workers ( n = 99; 49.7%), managers ( n = 86; 43.2%), and administrators ( n = 14; 7%). The two confirmatory factor models each showed a good fit in explaining sample statistics, corroborating the capacity of the scale to provide a total score of resilience and sub-scores for organizational resilience, network-based resilience, skill-based resilience, and individual-based resilience. The Molenaar-Sijtsma coefficients (internal consistency) ranged between 0.889 and 0.927. The SEOR enables managers and policy-makers to comprehensively screen resilience in healthcare from an epidemiological perspective.
The role of language in probation: A creative conversation
Authors: Phillips Jake , Bower Rachel
Published: April 2023

It is underpinned by our belief that language, including the ways we describe people, has important effects in the world. The piece consists of two parts: a brief critical introduction, and a creative dialogue which reflects upon ten key words that have been used to describe people on probation.
Walking hand in hand: The role of affection-sharing in understanding the social network effect in same-sex, mixed-sex, and gender-diverse relationships
Authors: Blair Karen L , Hudson Chelsea , Holmberg Diane
Published: April 2023

Individuals who perceive greater support or approval for their relationships from friends and family also report greater relationship stability and commitment and better mental and physical health (known as the “social network effect”). These associations have been explained, in part, through three cognitive-affective processes: uncertainty reduction, cognitive balance, and dyadic identity formation. However, we know less about cognitive- behavioral mechanisms that might help explain the social network effect. In this study, we propose and test a model in which physical affection-sharing acts as one such behavioral mechanism. In a sample of 1848 individuals in same-sex ( n = 696), mixed-sex ( n = 1045), and gender-diverse ( n = 107) relationships, we found support for our overall model. Our findings suggest that perceived support for one’s relationships is a significant predictor of perceived support for physical affection-sharing, which in turn predicts the frequency of affection-sharing in private and public contexts and, ultimately, relationship well-being. However, we also found that relationship type moderates these associations, highlighting how the experience of sharing affection with one’s partner changes for many in marginalized relationships, especially in public. We conclude by discussing how our findings contribute to theories of social support for relationships, underscoring the importance of considering affective, cognitive, and behavioral factors relevant to the process. We also emphasize the understudied role of context in shaping affection-sharing experiences across all relationship types.
Influence of contrast agent on artificial intelligence-based CT low attenuation volume percentage measurement
Authors: Wiedbrauck Damian , Karczewski Maciej , Schoenberg Stefan O , Fink Christian , Kayed Hany
Published: April 2023

Background

Low attenuation volume percentage (LAV%) has been identified as a quantitative imaging biomarker for emphysema with good correlation with spirometry. The influence of intravenous contrast agent on LAV% and its correlation with spirometry is not well known.

Purpose

To evaluate the influence of intravenous contrast agent on artificial intelligence (AI)-based LAV% in correlation with spirometric Tiffeneau-Pinelli Index (TI).

Material and Methods

In a retrospective study, two groups of 47 patients (mean age 68.04 ± 12.64 and 67.89 ± 11.54 years) with either non-enhanced chest computed tomography (CT) or contrast-enhanced CT were compared. Using an AI-based software, LAV% was quantified using a threshold <−950 HU. TI was calculated from spirometry and pathologic airway obstruction was considered with a TI <70. The effect of contrast agent on LAV% and the relationship between TI and LAV% was analyzed. Correlation coefficients between TI and LAV% were compared for both groups.

Results

Patients with non-enhanced CT had a mean LAV% of 9.07 ± 7.53. Of them, 22 patients had a TI <70% and 25 patients a TI ≥70%. Patients with contrast-enhanced CT had a mean LAV% of 6.54 ± 4.62. Of them, 20 patients had a TI <70% and 27 patients had a TI ≥70%. Contrast agent did not show a major effect on LAV% ( P = 0.099) and the relationship between TI and LAV% ( P = 0.88). In both groups, a significant correlation between TI and LAV% was found (ρ = −0.317 for non-enhanced CT; ρ = −0.514 for contrast-enhanced CT). Difference between correlation coefficients was insignificant.

Conclusion

Our findings suggest that contrast agent does not influence LAV% nor its correlation with TI.
Sexuality and ageing: A mixed methods explorative study of older adult’s experiences, attitudes, and support needs
Authors: Portellos Amelia , Lynch Claire , Joosten Annette
Published: April 2023

Introduction:

Sexuality contributes to health and wellbeing, but it is often overlooked as an important occupation for older adults. Older adult studies focus on decreased participation and functioning in sexual acts. This study aimed to obtain perspectives and explore understandings and experiences of sexuality and of support needs, for typically ageing adults.

Method:

Seventy-five older adults aged 60 years and older participated in the online cross-sectional survey. Participants were primarily from Australia, the United States, and the United Kingdom. Closed questions were analyzed using descriptive and inferential statistics, and reflexive thematic analysis was used for open questions.

Results:

Throughout the ageing process, older adults continued to value their sexuality, expression, desire, and identity, though meanings and participation changed. Changes and challenges were overcome through openness, exploration, curiosity, valued relationships, and adaptations to ways of doing. Older adults identified being dissatisfied with current sexual health supports, resources, and services.

Conclusion:

Healthcare professionals need to develop intervention knowledge to address diverse needs, and better support older adults in sexuality through open discussion, addressing psychological, social, and health concerns as part of everyday practice. The development of standardized assessments and resources with consumer collaboration will ensure resources address multifaceted components of sexuality, and older adults’ needs.

Published: April 2023

Purpose:

The present study aimed to investigate for the first time the effects of melatonin (MEL) intake on oxidative stress and cellular damage during intradialytic exercise (IEX).

Methods:

Thirteen hemodialysis (HD) patients volunteered to participate in the current randomized crossover trial. Participants performed four HD sessions in four different conditions: (Exercise (EX)-MEL), (EX-Placebo (PLA)), (Control (C)-MEL), and (C-PLA). 3 mg of MEL or PLA were taken 60 min before starting exercise, or at the equivalent time in the C conditions. Blood samples were taken before HD (T0), immediately after the end of IEX (T1), 60 min after IEX (T2), or at the corresponding times in the C conditions to measure free radicals damage, antioxidant biomarkers, as well as biomarkers of muscle and liver damage.

Results:

Malondialdehyde and Advanced Oxidation Protein Products decreased in (C-MEL) ( p < 0.05, d = 2.19; p < 0.01, d = 0.99, respectively) at T2 compared to T0. Catalase and total thiol levels increased in (C-MEL) ( p < 0.01, d = 1.51; p < 0.01, d = 1.56, respectively) and in (EX-MEL) ( p = 0.01, d = 1.28; p < 0.01, d = 1.52, respectively) at T1 compared to T0. Total bilirubin levels increased in (EX-MEL) and (C-MEL) at T2 compared to T0 ( p < 0.001, d = 2.77; p < 0.001, d = 1.36, respectively), but only at T2 compared to T1 in (EX-MEL) ( p < 0.001, d = 1.67). In all conditions, uric acid levels decreased at T1 compared to T0 and at T2 compared to T1, while biomarkers of muscle and liver damage remained unchanged.

Conclusion:

This pilot study is the first to show that MEL ingestion, alone or combined with IEX, could improve oxidant-antioxidant balance during HD.
A comprehensive review of aluminium electrolysis and the waste generated by it
Authors: Li Xueke , Liu Yan , Zhang Ting-an
Published: April 2023

Aluminium is produced by electrolysis using alumina (Al2O3) as raw material and cryolite (Na3AlF6) as electrolyte. In this Hall–Héroult process, the energy consumption is relatively large, and solid wastes such as spent anodes and spent pot liner, flue gas and waste heat are generated. Therefore, this article discusses from the perspective of high energy consumption and high pollution and summarizes the methods to reduce energy consumption and solve pollution problems. The functions of carbon anode, carbon cathode, refractory material and sidewall in aluminium electrolysis cells are discussed in detail. The process of aluminium electrolysis and the ways to improve the current efficiency of aluminium electrolysis cells and reduce their energy consumption are outlined. The causes and treatment methods of spent anodes, spent cathodes, spent refractories and spent spot liner are reviewed. The research progress of waste heat recovery and aluminium electrolysis flue gas purification are analysed. And the future research directions of aluminium electrolysis flue gas are provided.
Study of the mechanical properties and failure behavior of a novel PA12 lattice sandwich structure
Authors: Zheng Hao , Zhang Ziyang , Yang Na , Wang Jianfeng , Zhao Lijun
Published: April 2023

In this study, a novel lattice structure with Y-shaped cores was designed. Specimens of the structure were fabricated using 3D printing technology for quasi-static compression tests. Numerical simulations were also performed to investigate the mechanical properties and failure behavior of the lattice structure. The numerical results are in good agreement with the experimental results. The numerical simulations are used to reveal the failure processes and failure mechanisms of structures with different relative densities. The results show that the relative density has significant effects on the mechanical properties of the lattice structure, and that different methods of changing the relative density lead to different results.
On youth participation and adult manipulation: Exploring the lowest rung of Hart’s ladder in a youth organization
Authors: Perry-Hazan Lotem , Bauml Anna
Published: April 2023

The study explored the intersection of youth participation in collective decision-making and adult manipulation. To explore this intersection, we use a case study of youth participation in a conflict regarding one youth organization splitting off from another. The findings showed that the manipulated participation had social, cognitive, and discursive facets. These multiple facets resulted in intense youth engagement in the conflict, which may blur the boundary between high-level participation and manipulation. The intersection of participation and manipulation is particularly relevant to youth organizations with strong participation ethos, which paradoxically may be fertile ground for the emergence of manipulated participation.
Visual negotiation of identity and settlement of Poles in the so-called Recovered Territories: East Side Story by Anne Peschken and Marek Pisarsky
Authors: Smolińska Marta
Published: April 2023

This text is an analysis of a series of pinhole photographs, by Anne Peschken and Marek Pisarsky (Urban Art), entitled East Side Story I (Myślibórz). Photo research on migration and arrival stories, 2019 on-going. The main thesis is that these photographs are a model example of images which, while addressing the theme of migration in the representational layer, also activate the processual and migratory nature of visual forms themselves. In order to substantiate this thesis, the East Side Story project is examined in the following contexts: critical border (art) studies; H. Belting’s anthropology of the image; memory studies; re-enactment; the blurriness of images made with a pinhole camera; A. Berleant’s re-thinking aesthetics and the notion of aesthetic embodiment. Reflecting on the tension between history, memory, identity and politics and activating the critical potential of borderscaping, Peschken and Pisarsky transform the landscape of the Polish-German borderland into an anachronistic narrative agent. The photographs from the East Side Story series are thus transgenerational corpographies of memory, showing that migration is a key and inalienable element of Polish history.
HRC for dual-robot intelligent assembly system based on multimodal perception
Authors: Duan Jianguo , Fang Yuan , Zhang Qinglei , Qin Jiyun
Published: April 2023

In the current intelligent manufacturing scenario, single-mode perception limits the accuracy and safety of the human-robot collaboration process, and cannot adapt to the assembly operation requirements of robots in complex industrial environments. To solve these problems, this paper proposes a Human-Robot Collaboration (HRC) framework for a dual-robot intelligent assembly system based on multimodal perception. This framework aims to provide multimodal information interaction for robot control through gesture perception, speech perception, human body perception, and visual perception. To verify the effectiveness of this framework, it was applied to the assembly scene of the integrally shrouded blade-rotor system. Experiments show that the multimodal perception dual-robot intelligent assembly system can better realize the HRC assembly of the integrally shrouded blade and improve the intelligence of the assembly process. It shows that the framework can promote robots to flexibly and accurately perceive information among people, robots, and objects to complete intelligent assembly. The multimodal information interaction effectively improves the operational robustness of the dual-robot intelligent assembly system in complex industrial environments and complex tasks.

Published: April 2023

In this paper, the effect of process parameter on functionally graded materials (FGMs) of Inconel 625 (IN625) and Austenitic steel (SS304L) deposited by laser directed energy deposition (LDED) are investigated. For this purpose, FGM walls of different gradient of mix of IN625 and SS304L at different layers are deposited on Austenitic steel (SS316L) substrate at different sets of process parameters. For this study, the process parameters considered are laser power ( PL): 1000, 1300 and 1600 W, and scanning speed ( v): 0.3, 0.5 and 0.7 m/min. Deposited samples are then subjected to different tests such as energy dispersive spectroscopy (EDS), microhardness, scanning electron microscopy (SEM), X-ray diffraction (XRD), optical microscopy (OM), and nanoindentation. Tests performed on the samples revealed different effects of parameters on the deposition of the FGM wall. Based on the comparison of results of mechanical and metallurgical tests, it is observed that either at PL = 1300 W and/or v = 0.5 m/min, among the considered process parameters, show comparatively better results than the others.
The influence of contact distribution shaping on the dynamic response of a wiper blade
Authors: Graham Bradley , Knowles James , Mavros Georgios
Published: April 2023

The primary function of windscreen wipers is to remove water and debris from the windscreen, ensuring the driver has a clear view of the road ahead. Predicting wiper performance at the design stage is therefore important to ensure their safe operation. There is hence a need to develop physics-based models of wiper performance that can be used as evaluative tools early in the design stage. This paper presents an analysis of the impact of changing screen curvature on the contact force distribution of a wiper blade and the subsequent effects on the transient dynamics. The contact distributions for three distinct screen curvatures and three loading points are calculated via FEA (finite element analysis) and subsequently analysed via multiple connected mass spring dampers to model the wiper blade lip transient dynamics. By analysing time and frequency domain data for several calculated contact distributions it is found that decreasing the screen curvature reduces the contact force at the centre of the blade, however, increases the amplitude of vibrations and range of frequencies observed. Additionally, it is found that moving the loading point towards the tip of the blade reduces the amplitude of vibrations, a result analogous to that of increasing the screen curvature. Based upon the understanding gained through this work the influence of design criteria on wiper blades can now be assessed, and several suggestions made as to how to reduce windscreen wiper noise.
Reduced circulating Tregs and positive pANCA were robustly associated with the occurrence of antiphospholipid syndrome in patients with systemic lupus erythematosus
Authors: Wang Jia , Guo Hong-Xia , Cheng Ting , Shi Lei , Zhang Sheng-Xiao , Li Xiao-Feng
Published: April 2023

Background

Systemic lupus erythematosus (SLE) is a typical chronic immune disorder with clinical heterogeneity. The systemic abnormal immune response not only challenges the diagnosis and treatment of the disease itself but also the secondary antiphospholipid syndrome (APS), characterized by recurrent arterial or venous thrombosis, recurrent spontaneous abortion, or stillbirth. Clinical interest has primarily focused on primary APS’s pathological and clinical features. However, differences in clinical features and laboratory indicators between SLE with or without APS are still lacking, especially differences between circulating lymphocytes, which are critical in the pathogenesis of SLE and its complications.

Methods

In this retrospective study, we collected and analyzed clinical characteristics, general laboratory indicators, immunological indicators, and circulating lymphocyte subsets of SLE with or without APS.

Results

Systemic lupus erythematosus with APS (SLE-APS) had elevated SLEDAI scores, hospitalization costs and time, and frequencies of central nervous system symptoms and spontaneous abortion compared with those without APS. SLE-APS had higher positive anti-Cardiolipin antibodies, anti-β2 Glycoprotein 1 antibodies, and perinuclear antineutrophil cytoplasmic antibody (pANCA) than none-APS patients. Compared with healthy controls (HCs), the circulating lymphocyte subsets were altered to some extent in all patients, especially in patients with SLE-APS. Reduced Tregs and positive pANCA were independent risk factors for SLE secondary APS.

Conclusion

The present study revealed a robust association between APS secondary to SLE and reduced Tregs and positive pANCA, which provides essential information regarding the diagnosis and therapeutic possibilities of APS secondary to SLE.
Disability Policy in the Context of Intersectionality, Contemporary Oppressions, and Injustices: Toward a Just Future
Authors: Kozleski Elizabeth B. , A. Proffitt William , Stepaniuk Inna
Published: April 2023

This article connects the pillars of the Americans with Disabilities Act (ADA) to the complexities of living and dying in the United States. Our argument navigates among the emancipatory intent of ADA and the lives of people whose access to power, emancipation, and transformation are compromised by the historical and contemporary divisions of difference that infuse everyday life. The gaps between the possibilities of public policy, missed opportunities, and current realities create a significant, lasting impact on generations of Americans. While we acknowledge the landmark significance of ADA, we also press the imperative to expand and strengthen its impact. This article is framed in intersectionality, the politics of difference, and the potential of social policy.
An origami-based adaptive vibration isolator with Yoshimura-patterned reconfigurable module
Authors: Suh Jong-Eun , Han Jae-Hung
Published: April 2023

In this paper, a novel concept of the adaptive vibration isolator is presented. The proposed adaptive isolator is based on the thin-walled Yoshimura-patterned tube, which is able to reconfigure its shape to tune the stiffness. Multiple numbers of reconfigurable modules compose the proposed vibration isolator; thus, the force transmissibility of the isolator can be adjusted by systematic reconfiguration of the modules to show the best performance for the subjected vibration environment. The paper presents the analytical and experimental analysis of the force transmissibility of the proposed adaptive vibration isolator. The dynamic equation of the motion for the isolator system is established, and the force transmissibility is analyzed for the various configuration that a single design can have. The prototype of the proposed adaptive isolator is manufactured with an embedded actuation mechanism for reconfiguration. The performance of the isolator is experimentally confirmed through the vibration test of the fabricated prototype. Both the results of the analytical and the experimental investigation well demonstrate the adaptive characteristics of the proposed isolator concept.

Authors: Doğan Runida , Doğan Aysel , Karasu Fatma , Bağci Nazlıcan
Published: April 2023

Background

Currently, palliative care plays an important role in increasingly aging populations and their long-term care needs. Surgical palliative care is important for improving quality of life. This study aimed to determine the knowledge level of nurses working in surgical clinics about palliative surgery.

Method

This research was conducted as a descriptive study. We included 182 nurses working in surgical clinics who agreed to participate and met the inclusion criteria for participation in the study. The Personal Information and Palliative Surgery Information Forms were used to collect data. Data were collected between November 30, and December 15, 2022. The analysis of the data obtained was performed using the Statistical Program in Social Sciences (SPSS), Version 25. The level of significance was set at P < .05.

Results

Nurses referred to palliative care as end-of-life care, 73.1% did not care for palliative care patients, and 84.6% did not receive training in palliative care. Surgical clinic nurses were found to have “moderate knowledge about palliative surgery. A statistically significant difference was found between the average palliative surgery knowledge of surgical clinic nurses and those trained in education and palliative care ( P < .05).

Conclusions

The results of the study showed that surgical clinic nurses had moderate knowledge about palliative surgery. Moreover, the nurses who have received training in palliative care and had high level of education exhibited a higher level of knowledge.
Poverty Simulation With Teacher Candidates to Increase Awareness About Poverty
Authors: Briscoe Patricia
Published: April 2023

Background: Research suggests that many educators hold inaccurate or incomplete perceptions of poverty leading to stereotyping of students living in poverty. It is important for future teachers to understand more about the complexities of poverty so they can bridge gaps between misconceptions and understanding for their students, families, and school communities. Purpose: This study examined teacher candidates’ preconceived thoughts and changes in perceptions toward poverty based on participation in an experiential learning activity (i.e., a poverty simulation). Methodology/Approach: The participants ( n = 94) were in their final term of a 2-year teacher education program in Ontario, Canada. This mixed-method study used a Community Action Poverty Simulation combined with the quantitative presurvey Undergraduate Perception of Poverty Tracking Survey and qualitative postgroup discussions. Findings/Conclusions: Results indicated that the poverty simulation was an effective tool for disrupting poverty perceptions and myths among teacher candidates and provided insight into further areas to increase understanding. Implications: Based on the findings, poverty simulations are a promising experiential learning process for teacher education programs as a cost-effective, consciousness-raising exercise that can prompt deeper levels of learning for teacher candidates and better prepare them to teach students living in poverty.
Examining FGC Survivor and FGC Impacted Community Involvement Behind FGM/C Legislation in the United States: A Response to Bader's “From the War on Terror to the Moral Crusade Against Female Genital Mutilation: Anti-Muslim Racism and Femonationalism in the United States”
Authors: Taher Mariya

As an American-born woman who grew up as a South Asian Dawoodi Bohra Muslim, I have been aware of female genital mutilation/cutting (FGM/C) my entire life. So I immediately agreed to give commentary on “From the War on Terror to the Moral Crusade Against Female Genital Mutilation: Anti-Muslim Racism and Femonationalisim in the United States” by Dina Bader. While I do not necessarily disagree with Bader's observations, I provide additional context to better understand the history of our current FGM/C laws in this country and the influence survivors and advocates’ have had in shaping them.
Developing parenthood through giving birth to a dead child – bereaved lesbian mothers’ maternity care experiences in Scandinavia
Authors: Røseth Idun , Hvidtjørn Dorte , Dahl Bente
Published: April 2023

This phenomenological study uses in-depth interviews to explore how six lesbian couples experience the loss of a child in the perinatal period. Our findings revealed the importance of developing queer parenthood through a meaningful birthing space facilitated by a midwife and enabling time and space to recognize love and beauty in the couple’s grief. Suboptimal maternity care or insensitive comments related to their lesbian status complicated the loss, while care providers’ acknowledgement and sensitivity to the specific needs of queer couples enabled them to be present in the moment and recognize and process their loss.
Parental separation and school dropout in adolescence
Authors: Karhina Kateryna , Bøe Tormod , Hysing Mari , Askeland Kristin G. , Nilsen Sondre A.
Published: April 2023

Aims:

To document the association between parental separation and school dropout in adolescence and to examine the factors that may potentially account for this association.

Methods:

Data stem from the large youth@hordaland study that was linked to the Norwegian National Educational Database to obtain objective measures of educational outcomes and disposable income ( N = 8323). Logistic regression analysis was used to investigate the association between parental separation and school dropout. A Fairlie post-regression decomposition was used to examine the influence of parental education, household income, health complaints, family cohesion, and peer problems in explaining the association between parental separation and school dropout.

Results:

Parental separation was associated with a higher odds ratio (OR) of school dropout in crude and adjusted (adjusted odds ratio (AOR)) analyses (OR=2.16, 95% confidence interval (CI) =1.90–2.45; AOR = 1.72, 95% CI = 1.50–2.00). About 31% of the higher odds of school dropout among adolescents with separated parents was explained by the covariates. The decomposition analysis suggested that parental education (43%) and disposable income (20%) accounted for most of the explained differences in school dropout.

Conclusions:

Adolescents with separated parents are at higher risk for not completing secondary education. Parental education and disposable income accounted for most of the explained differences in school dropout between the groups. Still, the majority of the difference in school dropout remained unaccounted for, indicating that the link between parental separation and school dropout is complex and likely influenced by multiple factors.
Cryptogames: The promises of blockchain for the future of the videogame industry
Authors: Egliston Ben , Carter Marcus
Published: April 2023

Videogames are an increasingly prominent use case for blockchain technology (what has been termed ‘cryptogaming’). Drawing on documents, such as industry presentations, social media posts, interviews and white papers, this article analyses discourses surrounding cryptogames, focusing on the claims made by cryptogame developers and investors. We ask two related research questions: What are the dominant visions of a cryptogaming future, imagined by and for various constituencies? And what sorts of values get realised in such an imagined future of game development and use? We argue that cryptogames imagine players and developers as financialised subjects, adopting attitudes and practices of risk and investment as salves to both microeconomic problems in the games industry as well as broader macroeconomic issues.
Unfinalizability: An exploration of a young child’s emergent identities through living stories
Authors: Pham Hoa , Gaffney Janet S
Published: April 2023

Drawing on a Bakhtinian idea of unfinalizability and a semiotics lens of multimodality, the authors conceptualize children's everyday narratives as chains of living stories that emerge at home and in early childhood education settings. In this study, the authors interpret the living stories and emergent identities of Dylan, a five-year-old Vietnamese boy, in Aotearoa New Zealand. Two narrative chains of Dylan's living stories were selected to represent his intersecting and emergent identities around the significant event of the birth of his sibling, when he became the eldest brother. The findings will inspire early childhood educators and researchers to value learnings derived from stories and use the pedagogy of unfinalizability in their interactions with young children.

Authors: Sun Hongze , Qin Weidong , Shao Wenchong , Zhou Haimeng , Wang Xiaowei , Jiang Jianjun , Ding Xiangjiu
Published: April 2023

Purpose:

Isolated infected iliac artery aneurysms (IIIAAs) are extremely rare, life-threatening, and intractable. This study aimed to evaluate the outcomes of endovascular treatment in patients with IIIAAs.

Methods:

A retrospective study was conducted for all patients who underwent endovascular treatment for IIIAAs between June 2012 and June 2022 in 3 hospitals. The clinical data and follow-up outcomes were reviewed and assessed.

Results:

Fifteen patients were included in this study. The median age was 69 years, 12 patients (80%) were men, and 8 (53%) had hypertension. Most of the patients presented with abdominal or lumbar pain (87%) and fever (60%). The offending pathogen was identified in 11 patients (73%). Fifteen patients had a total of 16 IIIAAs, with 12 (75%) involving the common iliac artery. The immediate technical success rate was 100%, and the 30-day mortality was 7%. Infection-related complications occurred in 2 patients (13%) during hospitalization who were treated by open surgery at a later stage. The median follow-up was 23 months (range: 6–80 months, mean: 32 ± 25 months). Aneurysm recurrence was identified in one patient (7%) 5 months after endovascular repair. It was managed by endovascular stent-graft repair with percutaneous catheter drainage. No patients died during the follow-up period.

Conclusion:

Endovascular treatment is feasible, safe, and effective for patients with IIIAAs, achieving acceptable clinical outcomes. Infection surveillance with essential reintervention should be considered for potential infection-related complications.

Clinical Impact

This study first reported that 15 patients underwent endovascular treatment for primary isolated infected iliac artery aneurysms (IIIAAs). It showed a good early and midterm outcomes. This is the first and largest multi-center study and the first literature review of IIIAAs. It provides an evidence that endovascular treatment is feasible, safe, and effective to treat IIIAAs. It suggests endovascular treatment is a promising alternative or a bridge to conventional open surgery for IIIAAs. This may promote endovascular therapy in the management of IIIAAs. It would help clinicians to make an appropriate treatment choice for IIIAAs.

Published: April 2023

Objective: To compare the 6-dimensional errors of different immobilization devices and body regions based on 3-dimensional cone beam computed tomography for image-guided radiotherapy and to further quantitatively evaluate the impact of rotational corrections on translational shifts and dose distribution based on anthropomorphic phantoms. Materials and Methods: Two hundred ninety patients with cone beam computed tomographies from 3835 fractions were retrospectively analyzed for brain, head & neck, chest, abdomen, pelvis, and breast cases. A phantom experiment was conducted to investigate the impact of rotational errors on translational shifts using cone beam computed tomography and the registration system. For the dosimetry study, pitch rotations were simulated by adjusting the breast bracket by ±2.5°. Roll and yaw rotations were simulated by rotating the gantry and couch in the planning system by ±3.0°, respectively. The original plan for the breast region was designed in the computed tomography image space without rotation. With the same planning parameters, the original plan was transplanted into the image space with different rotations for dose recalculation. The effect of these errors on the breast target and organs at risk was assessed by dose-volume histograms. Results: Most of the mean rotational errors in the breast region were >1°. A single uncorrected yaw of 3° caused a change of 2.9 mm in longitudinal translation. A phantom study for the breast region demonstrated that when the pitch rotations were −2.5° and 2.5° and roll and yaw were both 3°, the reductions in the planning target volumes-V50 Gy were 20.07% and 29.58% of the original values, respectively. When the pitch rotation was +2.5°, the left lung V5 Gy and heart Dmean were 7.49% and 165.76 Gy larger, respectively, than the original values. Conclusions: Uncorrected rotations may cause changes in the values and directions of translational shifts. Rotational corrections may improve the patient setup and dose distribution accuracy.
SPACE: a new modeling tool for supporting layout design of military command and control spaces
Authors: Wang Wenbi
Published: April 2023

Military command and control spaces are complex work environments and critical facilities for a military mission. This paper describes a newly developed modeling tool called SPACE (Spatial layout Planning and Analysis for Communication Effectiveness) for assisting layout design of such workplaces. As a Human Factors tool, SPACE provides common functions required for workspace modeling, including rapid workspace prototyping, versatile design visualization, and algorithmic layout assessment. One of its key features is a layout evaluation algorithm that enables objective assessment of floor plans based on their impact on operator communication and interaction efficiency. In this paper, the main functionalities of SPACE are explained using a case study where models were constructed to compare three layout options for a Joint Intelligence Center. The results revealed the pros and cons of each layout in facilitating team interaction involving different sensory domains. While all three layouts were deemed acceptable, an inward-facing boardroom style design was predicted to be optimal as it best balanced the need for direct sightline access, non-technology-mediated verbal conversations, and the physical effort associated with movement to collaborators’ workstations. This study demonstrated the usefulness of modeling and simulation to provide quantitative auditable data for supporting evidence-based decision-making in military system design.
Anxiolytic and Antidepressant Potential of Methanolic Extract of Neurada procumbens Linn. in Mice
Authors: Khalid Ahmed Awais , Jabeen Qaiser , Javaid Faraza
Published: April 2023

Neurada procumbens Linn. possesses a wide range of phytochemical and bioactive entities such as flavonoids and polyphenols that decrease the oxidative stress and enhance synaptic plasticity, resulting in accelerated healing processes. Almost all parts of the plant have been used in the traditional system of medicine for various disorders including its use as an anticonvulsant, sexual tonic, and anti-rheumatic agent. This study is designed to evaluate the anxiolytic and antidepressant activities of the methanolic crude extract of N. procumbens (Np.Cr) based on its use in traditional medicine and presence of the phytochemical constituents. Aqueous methanolic extract of Np.Cr was prepared under reduced pressure using rotary evaporator, and different chemical constituents were identified by phytochemical screening. Light/dark exploration, elevated plus maze (EPM), and hole board tests were used to assess the anxiolytic activity, while forced swim and tail suspension tests were used to assess the antidepressant potential of the crude extract. Treatment groups treated individually with 3 different doses; i.e., 50, 100, and 200 mg/kg of Np.Cr, showed a dose-dependent increase in time spent in light compartment and in open arms as well as increased number of head poking by the experimental animals. Np.Cr showed significant antidepressant potential ( P < .05) as evident from marked decrease in behavioral despair. Findings of the present study assure that N. procumbens possess significant anxiolytic and antidepressant potential with the demands of further investigations to identify the active compound(s) responsible for these pharmacological effects.
The importance of algorithm skills for informed Internet use
Authors: Gruber Jonathan , Hargittai Eszter
Published: April 2023

Using the Internet means encountering algorithmic processes that influence what information a user sees or hears. Existing research has shown that people's algorithm skills vary considerably, that they develop individual theories to explain these processes, and that their online behavior can reflect these understandings. Yet, there is little research on how algorithm skills enable people to use algorithms to their own benefit and to avoid harms they may elicit. To fill this gap in the literature, we explore the extent to which people understand how the online systems and services they use may be influenced by personal data that algorithms know about them, and whether users change their behavior based on this understanding. Analyzing 83 in-depth interviews from five countries about people's experiences with researching and searching for products and services online, we show how being aware of personal data collection helps people understand algorithmic processes. However, this does not necessarily enable users to influence algorithmic output, because currently, options that help users control the level of customization they encounter online are limited. Besides the empirical contributions, we discuss research design implications based on the diversity of the sample and our findings for studying algorithm skills.

Background

Commercial cigarette smoking is the leading modifiable risk factor for more than 16 types of cancer. Over one-third (35.5%) of transgender and gender-diverse (TGD) adults smoke cigarettes compared to 14.9% of cisgender adults. The objective of this paper is to describe the feasibility of enrolling and engaging with TGD persons in a digital photovoice study to examine smoking risk and protective factors through real-world experiences (Project SPRING).

Methods

The study comprised a purposeful sample of 47 TGD adults aged ≥18 years who currently smoke and live in the United States (March 2019–April 2020). They participated in three weeks of digital photovoice data collection using Facebook and Instagram closed groups. A subsample participated in focus groups to explore smoking risks and protective factors in greater depth. We summarized the enrollment strategies and accrual rates, participant engagement (posts, comments, and reactions) during the photovoice data collection to assess study feasibility, and respondent feedback on acceptability and likability during and after the study.

Results

Participants were recruited via Facebook/Instagram advertising ( n = 33) and via Craigslist/word-of-mouth ( n = 14). Costs ranged from $29 via Craigslist/word-of-mouth to $68 per recruited participant via Facebook/Instagram advertising. On average, participants posted 17 pictures of smoking risks/protective factors, commented 15 times on others’ posts, and had 30 reactions within their group over 21 days. Participants’ rating of the acceptability and likability of the study were positive based on closed- and open-ended feedback.

Conclusion

The findings of this report will inform future research to engage with TGD community-engaged research to develop culturally tailored interventions to reduce smoking prevalence among TGD individuals.

Despite broad evidence in the past demonstrating the relationships between personality traits and organizational citizenship behavior, research on organizational citizenship behavior from the perspective of emotional contagion has not received deserving attention to date. Drawing on the trait theory and affective event theory as an overarching reference, this study theorizes emotional contagion as a moderator by arguing that it improves the above relationship incrementally. This study conducted hierarchical multiple regression analysis to test the hypotheses and adopted the Johnson–Neyman method using SPSS PROCESS Macro to probe the pattern of the significant interactions. A total of 320 bank employees took part in the survey. The findings revealed, agreeableness and conscientiousness as significant predictors of organizational citizenship behavior. Furthermore, the above association was enhanced for employees at the conditional level of high emotional contagion. The study provides insight into recognizing the significance of employees’ emotional levels and their contribution to organizational growth.

Published: April 2023

COVID-19 infection has been found to precipitate hypercoagulability and transiently increase antiphospholipid antibodies. However, it is yet to be determined how likely these transient changes contribute to thrombotic events and antiphospholipid syndrome. We present a case in which antiphospholipid antibodies were detected in the presence of significant thromboses. The patient was subsequently treated for suspected catastrophic antiphospholipid syndrome following COVID-19 infection.
