No heaven but no longer hell? Tales of criminal victimization and shelter among irregular migrant men
Authors: De La Maza Díaz José Miguel , Leerkes Arjen
Published: March 2024

Irregular migrants are legally excluded from formal employment, regular housing markets, and unemployment benefits, and in the Netherlands, they are also excluded from governmentally funded homeless shelters. While alternative sheltering arrangements have emerged for specific irregular migrants (e.g. minors, victims of human trafficking), unaccompanied adult men were typically still excluded from institutionalized shelter. In 2019, however, the national government launched a sheltering pilot for irregular migrants, which involves unaccompanied adult men in particular. Based on qualitative fieldwork in Rotterdam, and using Van Dijk and Steinmetz’s risk model as a theoretical lens, we argue that irregular status, interacting with other relevant factors such as social capital, co-determines the men’s criminal victimization risks, and fear of crime. In addition, we show how access to shelter changed the meaning and therefore the consequences of irregular status, resulting in both ‘de-marginalization’ and ‘re-marginalization’: victimization risks were generally reported to be lower in the shelter than in the streets, but sheltering also introduced new risks, which were mostly attributed to the co-presence of other sheltered groups, especially marginalized European Union (EU) citizens with a stronger immigration status. Paying attention to immigration statuses, and how they are socially constructed, thus helps to shed light on contemporary criminal victimization risks.
Bayesian Inference for Repeated Measures Under Informative Sampling
Authors: Savitsky Terrance D. , León-Novelo Luis G. , Engle Helen
Published: March 2024

Survey data are often randomly drawn from an underlying population of inferential interest under a multistage, complex sampling design. A sampling weight proportional to the number of individuals in the population that each sampled individual represents is released. The sampling design is informative with respect to a response variable of interest if the variable correlates with the sampling weights. The distribution for the variables of interest differs in the sample and in the population, requiring correction to the sample distribution to approximate the population. We focus on model-based Bayesian inference for repeated (continuous) measures associated with each sampled individual. We devise a model for the joint estimation of response variable(s) of interest and sampling weights to account for the informative sampling design in a formulation that captures the association of the measures taken on the same individual incorporating individual-specific random-effects. We show that our approach yields correct population inference on the observed sample of units and compare its performance with competing method via simulation. Methods are compared using bias, mean square error, coverage, and length of credible intervals. We demonstrate our approach using a National Health and Nutrition Examination Survey dietary dataset modeling daily protein consumption.
Visualizing the Shelf Life of Population Forecasts: A Simple Approach to Communicating Forecast Uncertainty
Authors: Wilson Tom
Published: March 2024

It is widely appreciated that population forecasts are inherently uncertain. Researchers have responded by quantifying uncertainty using probabilistic forecasting methods. Yet despite several decades of development, probabilistic forecasts have gained little traction outside the academic sector. Therefore, this article suggests an alternative and simpler approach to estimating and communicating uncertainty which might be helpful for population forecast practitioners and users. Drawing on the naïve forecasts idea of Alho, it suggests creating “synthetic historical forecast errors” by running a regular deterministic projection model many times over recent decades. Then, borrowing from perishable food terminology, the “shelf life” of forecast variables, the number of years into the future the forecast is likely to remain “safe for consumption” (within a specified error tolerance), is estimated from the “historical” errors. The shelf lives are then applied to a current set of forecasts and presented in a simple manner in graphs and tables of forecasts using color-coding. The approach is illustrated through a case study of 2021-based population forecasts for Australia. It´s concluded that the approach offers a relatively straightforward way of estimating and communicating population forecast uncertainty.
Promoting social justice in the capitalist academy? Health equity and the Johns Hopkins University Michael Bloomberg School of Public Health
Authors: Medvedyuk Stella , Raphael Dennis
Published: March 2024

The past two decades have seen increasing mentions of health equity and the importance of addressing the social determinants of health in USA public health statements. Yet, there is little uptake of these concepts into USA public policy. We see this, in part, as being due to the unwillingness of the USA public health community – including its network of Masters of Public Health Programs – to address the fundamental cause of health inequities: the United States’ capitalist economic system which skews the distribution of the social determinants of health in favour of the wealthy and powerful. We illustrate this reluctance by examining how the Bloomberg School of Public Health of Johns Hopkins University conceptualises the promotion of health equity through its International Declaration of Health Rights. Nothing in the Declaration considers how the economic system threatens health yet it is presented as a model for public health education. We review its shortcomings and show how revision to it is unlikely since the School is endowed by its namesake billionaire Michael Bloomberg who has denounced any attempts at redistributing wealth and income in the service of public health. Evidence of how public health messaging is already shaped by powerful economic interests embedded within the United States’ capitalist system substantiates concerns that have been raised about such branding and its effects on public health discourse and action.
Effect of different nanofillers incorporation on HDPE/LDPE films nanocomposite
Authors: Dallé Danieli , Rossa Beltrami Lilian Vanessa , Borsoi Cleide , Zattera Ademir José
Published: March 2024

The objective of this study was to develop polymeric films of high-density polyethylene (HDPE)/low-density polyethylene (LDPE) that comprise 1 wt% of different nanofillers, that is, either nanofibrillated cellulose (NFC), montmorillonite clay (MMT), or graphene nanoplatelets (GNPs); the polymeric films were developed with and without the inclusion of a coupling agent (CA). The results indicated that all the samples that comprised nanofillers exhibited, at least, an increase of 3 to 25°C compared with that of the matrix and demonstrated higher stability at the beginning of the thermal degradation, as verified using TGA. In the DSC analysis of the samples that contained GNPs had highest crystallinity index (55%), having as the consequent improvement in the mechanical properties and in the oxygen permeation. The incorporation of GNPs provided a 127.71% increase in deformation at break and a lower value in oxygen permeability with 50.06 mL.cm.(cm2.s.cmHg)−1, when compared to the polymeric matrix. It was concluded that all the different nanofillers tested promoted distinct improvements in HDPE/LDPE films nanocomposite. It can be inferred that these modifications are related to the chemical composition, size and morphology of each nanofiller. Thereby, it is indicated that with the use of each nanofiller one must be in accordance with the necessary demand of each composite film.
Applicability evaluation of damage evolution models in simulating repeated low-velocity impact behavior of composite laminates
Authors: Zhang Haowei , Li Mengze , Zhou Junjie , Yang Di , Wang Han , Song Xiaowen , Ke Yinglin
Published: March 2024

This study aims to provide a valuable reference for selecting appropriate damage evolution models (DEMs) when simulating the behavior of repeated low-velocity impacts (LVIs). Four DEMs are systematically evaluated in simulating mechanical response, dissipated energy, damage evolution, and accumulation under three repeated impacts. 3D Puck failure criteria and various DEMs combined with element characteristic lengths associated with physical fracture modes are used to predict repeated LVI damage behavior. Delamination behavior is simulated by zero-thickness cohesive elements. Two damage indexes are proposed to quantify and compare the damage distribution and accumulation. The post-peak softening and LVI behavior predicted by four DEMs are compared and verified through representative volume elements simulation and LVI experiments. The findings reveal that DEMs have varying degrees of influence on the mechanical response, damage evolution, damage distribution, and accumulation under repeated impacts. The exponential models proposed by P. Maimı et al. and Matzenmiller et al. are more suitable to simulate mechanical response or damage accumulation behavior under repeated impacts than the linear damage evolution model due to their non-linear post-peak softening characteristics. In contrast, Linde model shows brittle behavior due to the rapid damage accumulation during repeated impacts, rendering it unsuitable for repeated impact simulation.
“I Don’t Come Here Just for the Food”: Manifestations of Care in Food Assistance Initiatives
Authors: Augusto Fábio Rafael
Published: March 2024

This paper seeks to understand the social role played by food assistance initiatives in Portugal. Based on the understanding that these organizations are “spaces of care,” it is possible to reflect on the support provided by them in a more comprehensive and integrative way. Therefore, the various care practices that emerge in these organizational contexts are explored. This study presents a qualitative comparative methodological approach and a range of ethnographic methods to explore the perspectives of different actors (supervisors, volunteers, and beneficiaries) within different models of food assistance (Surplus Food Redistribution Charity, Soup Kitchen, and Social Supermarket). The main results indicate the presence of several “improvised” and “veiled” care practices in the analyzed initiatives that go beyond food issues. These manifestations of care may stem from altruistic acts and/or function as a “remedial measure,” serving as a compensatory mechanism in response to services deemed inadequate.

The Effect of the Neuman Systems Model–Based Training and Follow-up on Self-Efficacy and Symptom Control in Patients Undergoing Chemotherapy
Authors: Dural Gül , Çitlik Saritaş Seyhan
Published: March 2024

In this article, the authors aimed to determine the effect of the training and follow-up based on the Neuman systems model provided to patients undergoing chemotherapy on their self-efficacy and symptom control. The study was carried out with a randomized controlled experimental study model design. The sample consisted of 102 patients including 52 in the experimental group and 50 in the control group. The data were collected using the Patient Information Form, the Cancer Behavior Inventory–Brief (CBI-B), and the Edmonton Symptom Assessment Scale (ESAS). A personal training program prepared according to the Neuman systems model was applied to the experimental group patients. In the intergroup comparison of the experimental and control group patients, there was an increase in the posttest CBI-B scores and a decrease in the ESAS scores in the experimental group compared to the control group, and the intergroup difference was statistically significant ( p < .05). According to the results, to improve the self-efficacy and symptom control in patients undergoing chemotherapy, using this education and follow-up program is recommended.

Improving Transitions in Care for the Child with Medical Complexity Using Betty Neuman’s Systems Model
Authors: Van Orne Julie A.
Published: March 2024

Children with medical complexity are an increasing population with frequent use of intensive care services within hospitals. As children’s health improves, they are often transferred to a general unit before being discharged to home. This transition often leads to an acute decline in health, resulting in emergent interventions. Betty Neuman’s systems model provides the foundation to guide prevention interventions on stress mitigation to promote stability. An evidence-based transition bundle of care may be a valuable tool to prevent stress at the time of transfer from the intensive care unit and prevent deterioration.
Faculty Worldviews: The Challenge of Diversity and Silos
Authors: Yancey Nan Russell
Published: March 2024

While much has been written about diversity and worldviews, too often an openness and respect for diversity of perspectives in teaching-learning seem veiled in calls for sameness in thinking about the world, education, and events. In this column, the author explores the issue of diversity of faculty perspectives in the teaching-learning of nursing. Thoughts are shared from the humanbecoming teaching-learning model, exploring the notion of synergistic patterning in creating a rich tapestry of teaching-learning of nursing.
‘As long as you have the guts’: The discourse of drug offending
Authors: Jing-Ying Guo , Li-Min Zhou
Published: March 2024

Despite the harsh punishment and measures taken to crack down on drug-related crimes in China, drug offending presents a growing threat. This paper, based on in-depth interviews with 24 drug offenders who are now under incarceration, explores how drug offending is described and presented. The results reveal that drug offending is not merely simplified as good or evil, but constructed as individuals’ only, attractive, or non-existent option. The implications of the results are briefly discussed in regard to the reduction in drug crimes and policy improvement.
Detecting climate-driven ecological changes in high-altitude lakes in the Sierra Nevada, California
Authors: Lopera-Congote Laura , McGlue Michael M. , Westover Karlyn S , Yeager Kevin , Streib Laura , Stone Jeffery R
Published: March 2024

Over the past several decades, increasing climate instability in the Sierra Nevada, California, expressed primarily as reduced winter precipitation and higher temperatures, has led to more frequent drought. High-altitude lakes in this region have been characterized as pristine ecosystems, but growing evidence suggests that they are responding acutely to climate change. To address this, we analyzed the diatom assemblages of two 210Pb dated sediment cores (Gull and June Lakes) from the eastern Sierra Nevada with the aim of assessing their sensitivity to and timing of responses to climate change at the end of the neoglacial (~1450 CE to ~1850 CE) and identifying how climate drivers can impact diatom communities. The nutrient cycles of both lakes have been disrupted by changes in thermal stratification, driven by increasing temperatures, as interpreted from the shift from a Stephanodiscus corruscus dominated ecosystem to a Stephanodiscus minutulus dominance. In this case, the June Lake (the deeper lake) diatom assemblage shifted from an assemblage representative of well mixed conditions to one representative of a stratified system before Gull Lake as a response to increasing temperatures and a strengthened thermocline. We relate the asynchronous change in the thermocline stability to basin morphology, where the deeper lake with a deeper thermocline is more sensitive to increasing temperatures. Further, generalized additive models (GAMs) allowed us to identify the onset of ecological change in both lakes, pointing to the termination of the Little Ice Age (LIA; ~1850 CE), revealing an acute response to changing climate.

Published: March 2024

Background

Tuberculosis (TB) is one of the most common infections among systemic lupus erythematosus (SLE) patients. We aimed to evaluate the global prevalence of TB infection and disease, its type, and medication risk factors in SLE patients.

Methods

We searched PubMed, Science Direct, EBSCO, and Web of Science databases from inception to April 30, 2023, and included studies assessing TB among SLE patients. We estimated the prevalence of TB disease (including type of TB disease), TB infection, and SLE medication as TB risk factors. Meta-analysis was performed using Stata 14.2 and Review Manager 5.3.

Results

Twenty-seven studies met the eligibility criteria. The global prevalence of TB disease was 4% (95% confidence interval (CI): 3–4%, n = 25) and TB infection was 18% (95% CI: 10–26%, n = 3). The pooled prevalence of pulmonary TB, extrapulmonary TB, and disseminated TB were 2% (95% CI: 2–3%, n = 20), 1% (95% CI: 1–2%, n = 17), and 1% (95% CI: 0–1%, n = 6), respectively. The 1-year cumulative glucocorticoid (GC) dose in SLE patients contracting TB was higher than in those without TB, having a mean difference of 2.56 (95% CI: 0.22–4.91, p < .00001, n = 3). The odd ratio of TB was 2.11 (95% CI: 1.01–4.41, p = .05, n = 3) in SLE patients receiving methylprednisolone (MP) pulse therapy as compared to those without MP pulse therapy. Other immunosuppressive agents were not significantly associated with TB.

Conclusion

TB prevalence in SLE was relatively high and associated with GC. Awareness of TB and lowering GC dose are warranted to alleviate the TB burden in SLE.
Applications of Engineered Skin Tissue for Cosmetic Component and Toxicology Detection
Authors: Wang Min , Zhang Linfeng , Hao Haojie , Yan Muyang , Zhu Ziying
Published: March 2024

The scale of the cosmetic market is increasing every day. There are many safety risks to cosmetics, but they benefit people at the same time. The skin can become red, swollen, itchy, chronically toxic, and senescent due to the misuse of cosmetics, triggering skin injuries, with contact dermatitis being the most common. Therefore, there is an urgent need for a system that can scientifically and rationally detect the composition and perform a toxicological assessment of cosmetic products. Traditional detection methods rely on instrumentation and method selection, which are less sensitive and more complex to perform. Engineered skin tissue has emerged with the advent of tissue engineering technology as an emerging bioengineering technology. The ideal engineered skin tissue is the basis for building good in vitro structures and physiological functions in this field. This review introduces the existing cosmetic testing and toxicological evaluation methods, the current development status, and the types and characteristics of engineered skin tissue. The application of engineered skin tissue in the field of cosmetic composition detection and toxicological evaluation, as well as the different types of tissue engineering scaffold materials and three-dimensional (3D) organoid preparation approaches, is highlighted in this review to provide methods and ideas for constructing the next engineered skin tissue for cosmetic raw material component analysis and toxicological evaluation.
Moral distress among acute mental health nurses: A systematic review
Authors: Lamoureux Sara , Mitchell Amy E , Forster Elizabeth M
Published: March 2024

Moral distress has been identified as an occupational hazard for clinicians caring for vulnerable populations. The aim of this systematic review was (i) to summarize the literature reporting on prevalence of, and factors related to, moral distress among nurses within acute mental health settings, and (ii) to examine the efficacy of interventions designed to address moral distress among nurses within this clinical setting. A comprehensive literature search was conducted in October 2022 utilizing Nursing & Allied Health, Embase, CINAHL, PsychInfo, and PubMed databases to identify eligible studies published in English from January 2000 to October 2022. Ten studies met inclusion criteria. Four quantitative studies assessed moral distress among nurses in acute mental health settings and examined relationships between moral distress and other psychological and work-related variables. Six qualitative studies explored the phenomenon of moral distress as experienced by nurses working in acute mental health settings. The quantitative studies assessed moral distress using the Moral Distress Scale for Psychiatric Nurses (MDS-P) or the Work-Related Moral Stress Questionnaire. These studies identified relationships between moral distress and emotional exhaustion, depersonalization, cynicism, poorer job satisfaction, less sense of coherence, poorer moral climate, and less experience of moral support. Qualitative studies revealed factors associated with moral distress, including lack of action, poor conduct by colleagues, time pressures, professional, policy and legal implications, aggression, and patient safety. No interventions targeting moral distress among nurses in acute mental health settings were identified. Overall, this review identified that moral distress is prevalent among nurses working in acute mental health settings and is associated with poorer outcomes for nurses, patients, and organizations. Research is urgently needed to develop and test evidence-based interventions to address moral distress among mental health nurses and to evaluate individual and system-level intervention effects on nurses, clinical care, and patient outcomes.
Nursing students’ attitude toward euthanasia following its legalization in Spain
Authors: Arreciado Marañón Antonia , García-Sierra Rosa , Busquet-Duran Xavier , Tort-Nasarre Gloria , Feijoo-Cid Maria
Published: March 2024

Background

Euthanasia is a controversial practice in many countries. Since Spain’s Euthanasia Law came into effect on March 24, 2021, healthcare providers have faced a new challenge since they must inform patients, provide care, accompany them, and implement the law. It also represents a new stumbling block at universities, which must adapt to regulatory changes and educate future professionals accordingly. Little is known about the attitude of nursing students in Spain toward euthanasia since this law was implemented.

Objective

This study aims to answer the following research questions: What is the attitude of nursing students toward euthanasia? What factors influence this attitude?

Research design

A cross-sectional study was conducted using an online questionnaire.

Participants and research context

The study population comprised all nursing students at a public university in Barcelona ( n = 444), Spain, during the 2022–2023 academic year. The validated Spanish version of the Euthanasia Attitude Scale was employed. A bivariate analysis was performed.

Ethical considerations

The university Ethics Committee (CEEAH 6247) approved this study. All participating students signed an informed consent form. Participation was voluntary, and data anonymity and confidentiality were guaranteed.

Results

Two hundred and forty-four nursing students responded to the questionnaire. The mean total score was 79.64. Participants with religious beliefs presented lower scores, indicating a more negative attitude toward euthanasia. Participants in their second, third, or fourth year of the nursing degree scored higher, demonstrating a more positive attitude.

Conclusions

The attitude of nursing students toward euthanasia was remarkably positive. Working on ethical content during the degree course and clinical practice are factors that help to develop a more positive attitude. In addition, nursing education should encourage professional aspects to prevail over religious beliefs in euthanasia situations.
Influence of Talar and Calcaneal Morphology on Subtalar Kinematics During Walking
Authors: Yamamoto Tetsuya , Paulus Paige , Setliff Joshua C. , Hogan MaCalus V. , Anderst William J.
Published: March 2024

Background:

Cadaver biomechanical testing suggests that the morphology of articulating bones contributes to the stability of the joints and determines their kinematics; however, there are no studies examining the correlation between bone morphology and kinematics of the subtalar joint. The purpose of this study was to investigate the influence of talar and calcaneal morphology on subtalar kinematics during walking in healthy individuals.

Methods:

Forty ankles (20 healthy subjects, 10 women/10 men) were included. Participants walked at a self-selected pace while synchronized biplane radiographs of the hindfoot were acquired at 100 images per second during stance. Motion of the talus and calcaneus was tracked using a validated volumetric model-based tracking process, and subtalar kinematics were calculated. Talar and calcaneal morphology were evaluated using statistical shape modeling. Pearson correlation coefficients were used to assess the relationship between subtalar kinematics and the morphology features of the talus and calcaneus.

Results:

This study found that a shallower posterior facet of the talus was correlated with the subtalar joint being in more dorsiflexion, more inversion, and more internal rotation, and higher curvature in the posterior facet was correlated with more inversion and eversion range of motion during stance. In the calcaneus, a gentler slope of the middle facet was correlated with greater subtalar inversion.

Conclusion:

The morphology of the posterior facet of the talus was found to a primary factor driving multiplanar subtalar joint kinematics during the stance phase of gait.

Clinical Relevance:

This new knowledge relating form and function in the hindfoot may assist in identifying individuals susceptible to subtalar instability and in improving implant design to achieve desired kinematics after surgery.
3D Analysis of Joint-Sparing Charcot-Marie-Tooth Surgery Effect on Initial Standing Foot Alignment
Authors: Song Jae Hwang , Michalski Max P. , Pfeffer Glenn B.
Published: March 2024

Background:

The complex deformities in cavovarus feet of Charcot-Marie-Tooth (CMT) disease are difficult to evaluate. The aim of this study was to quantify the initial standing alignment correction achieved after joint-sparing CMT cavovarus reconstruction using pre- and postoperative weightbearing computed tomography (WBCT).

Methods:

Twenty-nine CMT cavovarus reconstructions were retrospectively analyzed. Three-dimensional measurements were performed using semiautomated software (Bonelogic 2.1) to investigate changes in sagittal, axial, and coronal parameters. Pre- and postoperative data were compared, along with normative data. Correlation among the preoperative measurements and the amount of correction in sagittal, axial, and coronal parameters were analyzed.

Results

The sagittal, axial, and coronal malalignment of the hindfoot, and the sagittal and axial malalignment of the forefoot, was significantly improved after corrective surgery ( P < .05). Sagittal Meary angle (from 14.8 to 0.1 degrees), axial talonavicular angle (TNA, from 3.6 to 19.2 degrees), and coronal hindfoot alignment (from 11.0 to −11.1 degrees) showed significant changes postoperatively ( P < .001). Hindfoot, forefoot sagittal, and forefoot axial parameters reached comparable outcomes compared with normative value ( P > .05). Regarding amount of correction, Spearman correlation demonstrated that axial Meary angle and TNA were most strongly related to improvement in sagittal Meary angle and coronal hindfoot alignment.

Conclusion:

Preoperative and postoperative WBCT measurements demonstrated that joint sparing CMT cavovarus reconstruction significantly improved sagittal, axial, and coronal deformities of CMT, and sagittal Meary angle was restored toward normative values. Apparent axial plane correction, the majority of which occurred at the talonavicular joint, had the strongest correlation with deformity correction in multiple planes. This suggests that soft tissue releases and correction of the talonavicular joint may be a key component of a cavovarus foot correction.
Treatment of Symptomatic Os Supranaviculare in Athletes
Authors: Sugimoto Kazuya , Isomoto Shinji , Miura Kimio , Wakiyama Sayaka , Yoneda Azusa , Taniguchi Akira , Tanaka Yasuhito
Published: March 2024

Background:

Although the incidence of os supranaviculare (OSSN) is generally low, symptomatic OSSN affects athletes. The aim of this study was to assess the variations of OSSN and the results of osteosynthesis between the OSSN and the navicular bone.

Methods:

Eleven feet of 10 elite athletes with symptomatic OSSN were treated. There were 3 male and 7 female patients with an average age of 19 years. Eight feet exhibited navicular stress fracture (NSF). Operative treatment was performed in 9 feet of 8 patients and 2 conservatively. Seven OSSNs were fixed with 1 or 2 screw(s) according to their size, using an autologous bone graft. The accompanying NSF was also treated surgically in 4 feet. Foot condition was evaluated using the Japanese Society for Surgery of the Foot (JSSF) midfoot rating scale and sports activity score of the Self-Administered Foot Evaluation Questionnaire (SAFE-Q).

Results:

The median OSSN was 12.7 mm in width, 5.6 mm in length, and 6.6 mm in height. The dorsal surface of the OSSN required at least 70 mm2 to be fixed using 2 screws. Seven OSSNs of 6 patients treated surgically successfully fused with the navicular. Two small OSSNs that were not stabilized with screws also fused after surgical treatment for NSF. However, one of the 2 OSSNs with NSF treated nonoperatively did not achieve fusion. The patients were followed up for 24-161 months. The median JSSF score improved from 87 to 97.7 postoperatively ( P = .00312). The median postoperative SAFE-Q sports score was 84.8. All patients returned to their original activities.

Conclusion:

Our results suggest that osteosynthesis with autologous bone graft was effective for symptomatic OSSNs. Even when the OSSN was small and not suitable for internal fixation, treatment of NSF was effective for union of OSSNs. The OSSN possibly belongs to a part or subtype of NSF.
Measuring Process Factors of Fluid Reasoning Using Multidimensional Computerized Adaptive Testing
Authors: Akhtar Hanif , Kovacs Kristof
Published: March 2024

Although many fluid reasoning (Gf) tests have been developed, there is a lack of figural tests measuring its lower-order process factors simultaneously. The present article introduces the development of the Multidimensional Induction-Deduction Computerized Adaptive Test (MID-CAT) to measure two process factors of Gf. The MID-CAT is designed to provide an instrument that is flexible, efficient, and entirely free for non-commercial use. We created 530 items and administered them to a sample of N = 2,247. Items were fitted and calibrated using the Rasch model. The results indicate that the final item pool has a wide range of difficulties that could precisely measure a wide range of test-takers’ abilities. A simulation study also indicates that MID-CAT provides greater measurement efficiency than separate-unidimensional CAT or fixed-item test. In the discussion, we provide perspectives on how the MID-CAT can be used for future research.
Clinical Impact of Covid-19 Omicron Variant on Patients in Home Health Care

Published: March 2024

Coronavirus disease 2019 (COVID-19) risk factors for hospitalization and mortality have been reported to be older age, comorbidities, and vaccination status. However, its clinical course and the risk of hospitalization and mortality in patients who received home health care for their predisposing status and diseases remain unclear. This study aimed to determine the characteristics and outcomes of these patients after being infected with the Omicron variant of COVID-19. This retrospective study included 33 patients diagnosed with COVID-19 after we initiated home health care. We classified the patients into 2 groups, that is, hospitalization (n = 7) and non-hospitalization (n = 26), and non-survival (n = 6) and survival (n = 27) and compared their backgrounds. COVID-19 severity was an affecting factor in hospitalization and survival. The nursing care environments and low daily life activities also affected hospitalization but not survival. The proportion of patients with terminal malignancies (50.0% vs 3.7%, p = .017) and the Charlson Comorbidity Index (5.0 vs 2.0, p = .096) were higher in the non-survival than in the survival group. Some patients had urinary tract infections and persistent weight and appetite loss (post COVID-19 syndrome), regardless of this improvement. Serum IL-6 levels were higher in patients with post COVID-19 syndrome than those without symptoms. Optimizing the nursing care environment is essential to continue home health care and lower the hospitalization rate even with SARS-CoV-2 infection. Post COVID-19 syndrome, such as appetite and weight loss, are associated with IL-6-induced inflammation.
DGEMM on integer matrix multiplication unit
Authors: Ootomo Hiroyuki , Ozaki Katsuhisa , Yokota Rio
Published: March 2024

Deep learning hardware achieves high throughput and low power consumption by reducing computing precision and specializing in matrix multiplication. For machine learning inference, fixed-point value computation is commonplace, where the input and output values and the model parameters are quantized. Thus, many processors are now equipped with fast integer matrix multiplication units (IMMU). It is of significant interest to find a way to harness these IMMUs to improve the performance of HPC applications while maintaining accuracy. We focus on computing double-precision equivalent matrix multiplication using the Ozaki scheme, which computes a high-precision matrix multiplication by using lower-precision computing units, and show the advantages and disadvantages of using IMMU. The experiment using integer Tensor Cores shows that we can compute double-precision matrix multiplication faster than cuBLAS and an existing Ozaki scheme implementation on FP16 Tensor Cores on NVIDIA consumer GPUs. Furthermore, we demonstrate accelerating a quantum circuit simulation by up to 4.85 while maintaining the FP64 accuracy.

Indigenous methodology is a living methodology of doing research in a good way that honours respectful relationships with Indigenous Peoples and communities in which knowledge is co-created and ownership is shared. Guided by Indigenous methodologies, the Urban Indigenous Collective Governance Circle was co-developed for urban Indigenous health research. The Collective Governance uses approaches that stay true to the connectedness of Traditional Knowledges, Indigenous protocols, and relational processes. Relationality ensures guidance from knowledge, experiences, and wisdom of community members participating in, leading, and benefitted by the research. The Governance Circle ensures that self-determination and self-governance is realized through Indigenous health research; research responsive to community-identified priorities, leadership, control, approval, and community ownership.

Introduction:

Pulmonary artery aneurysms encompass a wide range of presentations and forms. Mycotic aneurysms represent a particular subset of focal dilatation of the vessel wall with high morbidity and mortality rates. Herein, we report the case of a 32 year old patient, with a prior history of ventricular septal defect presenting with a mycotic pulmonary artery aneurysm associated with infective endocarditis and septic emboli.

Case presentation:

We present the case of a 32 year old male with known history of congenital ventricular septal defect presented to the emergency department with signs of sepsis and dyspnea. Blood cultures were positive for methicillin-sensitive Staphylococcus aureus. An echocardiogram found evidence of endocarditis with multiples intra cavitary vegetations. A CT angiogram demonstrated major right ventricular dilatation, multiple nodules and peripheral opacities, scattered throughout the lungs, indicative of septic emboli. Segmental saccular dilatation of the left lateral basal pulmonary artery consistent with a mycotic aneurysm formation was found. The patient was started on intravenous antibiotics and given the overall satisfactory evolution a conservative approach was pursued. The patient was discharged with antibiotics and scheduled for surgical repair of the ventricular septal defect.

Conclusion:

To our knowledge, mycotic aneurysms associated to congenital heart malformation like ventricular septal wall defect remains a rare condition with few reported cases in the literature. Being aware of this entity is important for every practicing radiologist to allow for early diagnosis and treatment.
Enhancing dual language learners’ language learning through parent–teacher partnerships
Authors: Zhang Xiaoyue , Jiang Lianjiang
Published: March 2024

Families of dual language learners (DLLs) and their linguistic resources play a crucial role in fostering children’s language development. However, there is still a dearth of empirical studies investigating whether bilingual teachers view the families of DLLs and their language resources as assets, and how they implement family engagement practices to leverage these language assets in teaching DLLs. This study examined the family engagement perspectives and practices of five bilingual teachers in New York City (NYC) early childhood classrooms. Qualitative data were collected using online questionnaires and semi-structured interviews. The findings suggest that bilingual teachers hold a strength-based view of DLLs’ parents and their language resources to support their children’s language learning. Controversially, they demonstrated a mixture of deficit- and strength-based approaches to parental engagement, ranging from educating parents about English homework strategies to arranging classroom events in which parents could highlight their home language practices. Concurrently, teachers were fully aware of the importance of DLLs’ home linguistic resources in supporting students’ language learning, yet they maintained instructional practices that kept DLLs’ home and school language repertoires separate. The implications for fostering strength-based perspectives on DLL families and strength-based DLL family engagement strategies are discussed.

Saudi buildings use approximately 29% of the primary energy and about 80% of the electrical energy. Because of the hot and dry climate, air conditioners consume a lot of electrical energy to attain a comfortable temperature indoors. More than 70% of Saudi buildings need to be thermally insulated. The objective of this study is to assess the existing energy saving of public schools in Saudi Arabia. Indoor thermal environment monitoring of three school buildings has been undertaken by employing LSI LASTEM ‘R-LOG’ data loggers, and electric energy bills of the schools were also collected. The school building was modelled using DesignBuilder software, which was utilized to investigate the impact of various modifications made to the building envelopes, including changes to building orientation, the inclusion of thermal insulation layers, various types of glass and shading devices. According to the findings, implementing appropriate building envelope design techniques for existing schools can lead to significant reductions in cooling and overall energy consumption, with savings of 30% and 19%, respectively. After applying these strategies collectively, the school managed to reduce its total annual electricity consumption by nearly 19.2%, resulting in a decrease from 279.13 MWh to 225.5 MWh per year.
Innovation from Inclusivity: The Effect of Team Diversity on Clean Meat Acceptance

In an era where corporate social responsibility (CSR) dominates organizational agendas, the dimension of team diversity remains largely overshadowed. Despite its transformative potential, the interplay between team diversity and consumer product acceptance has been under-represented in the literature. This study illuminates the potency of team diversity as a critical CSR dimension, revealing its impact on bolstering product acceptance. In the context of clean meat, two experimental studies demonstrate that consumers are more willing to try a product developed by a company with a more diverse team (e.g. race and gender), as such firms are likely to account for a diversity of perspectives, thus enhancing consumer trust. Additionally, perceived authenticity moderates this effect, in that consumers of more authentic brands will be more trusting, regardless of the level of team diversity. The study provides critical insights into how consumers’ perception of team diversity within the firm influences product adoption, and how both team diversity and perceived authenticity drive trustworthiness. The findings offer practical implications for marketers of clean meat and other novel products to accelerate market acceptance and consequently, address broader societal challenges, whilst emphasizing the importance of fostering diversity and promoting brand authenticity.
From the auction block to the Tinder swipe: Black women’s experiences with fetishization on dating apps

Published: March 2024

The digital has been celebrated for its objectivity and lack of bias, yet digital media scholars have addressed the ways that inequity is embedded in technology. What is often missing from this discourse is the voices of Black women. Drawing on interviews with 20 self-identified Black and African American women, aged 18–30, who have used dating apps in the preceding 6 months, we invited participants to share their experiences with online dating and racial fetishization. Using reflexive thematic analysis, we explore how Black women perceive and navigate racial fetishization and stereotypes often informed by racialized and gendered ideologies. Our findings trace Black women’s movements through three phases of the dating process in which participants discussed feeling fetishized; a sentiment that we identify as racial desire that is rooted in colonialist ambitions.
Simulation study on the cavitation distribution in the ball valve of a common rail injector

Published: March 2024

A transient-state numerical simulation is conducted to investigate the cavitation flow in the ball valve of a common rail (CR) injector. The computational fluid dynamics (CFD) software, employing the RANS turbulence model, is employed for this purpose. The study aims to analyze the characteristics and underlying causes of the uneven distribution of cavitation in the ball valve. The results reveal a significant occurrence of cavitation, exhibiting an uneven distribution along the walls of both the ball and the valve seat. Notably, the initiation position of the intense cavitation region on the wall of the ball is observed to lag behind that on the wall of the valve seat. The intense cavitation region on the wall of the ball is found to reside behind the sealing surface of the ball valve. The intense cavitation region on the wall of the ball is located behind the sealing surface of the ball valve. This region experiences flow separation caused by main flow detour, resulting in the formation of vortices that entrapped the cavitation cloud, thus fostering the development of intense cavitation. Conversely, the intense cavitation region on the wall of the valve seat originates from the entrance of the ball valve. This can be attributed to the sudden change in geometry at the entrance, leading to a significant pressure drop and inducing cavitation based on geometric factors. Furthermore, the stagnation effect caused by the ball exacerbates the discrepancy in the distribution of the intense cavitation region between the ball and the valve seat.
