Where Does the Future of an Intellectual Structure of the EAQ Corpus Lie? A Response to Hallinger et al.'s Empirical Reflection
Authors: Wang Yinying
Published: October 2023

Purpose: This response cautions against narrowly interpreting Hallinger's bibliometric findings on the intellectual structure and impact of Educational Administration Quarterly (EAQ). It highlights two main issues when using citations to measure influence. Response Argument: First, citations reflect a variety of motivations beyond acknowledging intellectual contribution, such as persuasion, allegiance-signaling, and preferential attachment. The sleeping beauty phenomenon and citation bias can further distort the interpretation of bibliometric findings. Second, setting thresholds for co-citation networks renders the periphery invisible; however, the periphery contains anomalies that could spur future paradigm shifts. Implications: The response urges embracing diverse views and nuanced interpretations to prevent perpetuating existing inequalities.
Negative temperature coefficient and positive temperature coefficient behavior of electrically conductive silicone/carbon black composites
Authors: Nagel Julian , Hanemann Thomas , Rapp Bastian E. , Finnah Guido
Published: October 2023

As highlighted in several studies, the thermal expansion of the polymer matrix plays an important role with respect to the thermo-electrical behavior of conductive composites. Although it is known that the crosslink density of polymers affects the thermal expansion of polymers, no studies are known on whether different crosslink densities can affect the thermoelectric behavior of electrically conductive composites. In this study, silicone/carbon black composites with different crosslink densities, were investigated with respect to their self-heating properties under applied voltages and their thermo-electrical behaviors like positive and negative temperature coefficients. Specific resistances ρ about 55 +/− 4.5 Ω-cm have been achieved and uniquely high negative temperature as well as low temperature coefficients were demonstrated, which make these materials interesting for sensor-technical applications. Regarding their self-heating behaviors, average surface temperatures of up to 147°C were measured, which further make these materials very interesting as flexible heating elements. Finally, it could be shown that the crosslink density of addition curing silicones is adjustable over a wide range and that it can be further significantly changed by the addition of carbon black and platinum content.
Quantitative Assessment of Systematic Bias: A Guide for Researchers
Authors: Bond J.C. , Fox M.P. , Wise L.A. , Heaton B.
Published: October 2023

Observational research provides valuable opportunities to advance oral health science but is limited by vulnerabilities to systematic bias, including unmeasured confounding, errors in variable measurement, or bias in the creation of study populations and/or analytic samples. The potential influence of systematic biases on observed results is often only briefly mentioned among the discussion of limitations of a given study, despite existing methods that support detailed assessments of their potential effects. Quantitative bias analysis is a set of methodological techniques that, when applied to observational data, can provide important context to aid in the interpretation and integration of observational research findings into the broader body of oral health research. Specifically, these methods were developed to provide quantitative estimates of the potential magnitude and direction of the influence of systematic biases on observed results. We aim to encourage and facilitate the broad adoption of quantitative bias analyses into observational oral health research. To this end, we provide an overview of quantitative bias analysis techniques, including a step-by-step implementation guide. We also provide a detailed appendix that guides readers through an applied example using real data obtained from a prospective observational cohort study of preconception periodontitis in relation to time to pregnancy. Quantitative bias analysis methods are available to all investigators. When appropriately applied to observational studies, findings from such studies can have a greater impact in the broader research context.

There is a need for Vietnamese language education for the Vietnamese American community in the United States, and the Vietnamese Language Program at Westminster High School (WHS) in Orange County, California, has been able to preserve the Vietnamese language. Students in the program also learn about their heritage and culture to stay connected to their families and community. Author Pauline Phi Nguyên Đồng, a Vietnamese language teacher at the high school, suggests that the WHS Vietnamese Language Program is a model for how heritage language programs can be sustained in schools and communities.
Backtalk: Minority-Serving Institutions: Leaders in teacher education innovation
Authors: Ginsberg Alice E. , Gasman Marybeth , Samayoa Andrés Castro
Published: October 2023

The clinical experience is one of the most important parts of teacher education, but many teacher candidates have little field experience before becoming teachers or have field experience that it reserved for the end of their program and is disconnected from their coursework. Alice E. Ginsberg, Marybeth Gasman, and Andrés Castro Samayoa share how Minority-Serving Institutions (MSIs) are developing teacher education models that enable candidates to spend more time in preK-12 classrooms throughout their education and to see how their university-level coursework connects to classroom practice. Because MSIs prioritize connecting to the community, instead of focusing primarily on research and publishing, teacher educators are able to spend more time at school sites, solidifying the connection between teacher education and the preK-12 classroom.
Out the Gate: Towards a Rhizomatic Understanding of Methamphetamine Use in Aotearoa-New Zealand
Authors: Bax Trent
Published: October 2023

As part of an interview-based qualitative study on the life-course of people who formally used methamphetamine in Aotearoa-New Zealand, this paper uses Deleuze and Guattari's rhizomatic perspective to trace the specific effects and particular relations involved in methamphetamine use. The methamphetamine-using trajectory for the 42 former users is a multifaceted and constantly fluctuating process involving multiple entries, exists, pathways, and restarts. By amplifying and enlightening the user, methamphetamine use begins by liberating desire through sending the user “out the gate,” but long-term high-dose use can end up constraining and repressing subjectivity and cyclically producing adverse psychological, emotional, interpersonal, and social effects. As a metamorphic process that produces transformative change, long-term high-dose methamphetamine use is a nonlinear rollercoaster ride that typically leads to a downward spiral whereby life stagnates, shrinks, or regresses. By undermining productive and transformative connections, the life of the long-term high-dose methamphetamine user typically—but not inevitably—involves revolving instead of evolving. Against a linear and deterministic popular media-generated narrative about methamphetamine use, a rhizomatic perspective emphasizes the potential for transformation by focusing upon the situational and interactional processes involved in users who undergo complex and varied temporary changes. From Deleuze and Guattari's perspective, disentangling from long-term high-dose methamphetamine use requires activating new relationships and possibilities for desire by forming meaningful biopsychosocial connections.
Sexual Minorities’ Uncertainty About Their Romantic Partner’s Communication With Their Family: Applying the Theory of Motivated Information Management
Authors: Schrodt Paul , Ledbetter Andrew M. , Markham Austyn
Published: October 2023

Using the theory of motivated information management (TMIM), this study tested the degree to which sexual minorities’ uncertainty discrepancy about their partner’s communication about their relationship to their family of origin predicted their information management strategies and relational quality (i.e., closeness and satisfaction). Participants included 111 sexual minorities involved in a monogamous romantic relationship. Results supported the theoretic logic of the TMIM, as uncertainty discrepancy positively predicted negative emotions, which in turn negatively predicted SMs’ outcome expectancies and efficacy assessments but positively predicted direct and indirect information seeking. Indirect effects emerged for uncertainty discrepancy on direct information seeking and information avoidance, as well as for relational closeness and satisfaction, via the mechanisms specified by the TMIM. Importantly, this study reveals relational ambivalence that sexual minorities may experience as a result of managing their uncertainty about their partner’s relationship disclosures to their partner’s family-of-origin.
Short-term photovoltaic power prediction based on fractional Levy stable motion
Authors: Zheng Hongqing , Song Wanqing , Cheng Wei , Cattani Carlo , Kudreyko Aleksey
Published: October 2023

Accurate prediction of photovoltaic (PV) power generation is the key to daily dispatch management and safe and stable grid operation. In order to improve the accuracy of the prediction, a finite iterative PV power prediction model with long range dependence (LRD) characteristics was developed using fractional Lévy stable motion (fLsm) and applied to a real dataset collected in the DKASC photovoltaic system in Alice Springs, Australia. The LRD prediction model considers the influence of current and past trends in the stochastic series on the future trends. Firstly, the calculation of the maximum steps prediction was introduced based on the maximum Lyapunov. The maximum prediction steps could provide the prediction steps for subsequent prediction models. Secondly, the order stochastic differential equation (FSDE) which describes the fLsm can be obtained. The parameters of the FSDE were estimated by using a novel characteristic function method. The PV power forecasting model with the LRD characteristics was obtained by discretization of FSDE. By comparing statistical performance indicators such as root max error, mean square error with Conv-LSTM, BiLSTM, and GA-LSTM models, the performance of the proposed fLsm model has been demonstrated. The proposed methods can provide better theoretical support for the stable and safe operation of PV grid connection. They have high reference value for grid dispatching department.

Divya , Shukla Kshama , Devi Shylaja
Published: October 2023

Background:

Among the Indian adolescents, the prevalence of psychiatric morbidity and alcohol use disorders (AUD) are 7.3% and 1.3%. However, no separate data are available for indigenous tribal populations. This study estimated the prevalence of psychiatric morbidity and AUD and associated socio-demographic factors among adolescents in the tribal communities in three widely varying states in India.

Methods:

Using validated Indian versions of the MINI 6.0, MINI Kid 6.0, and ICD-10 criteria, we conducted a cross-sectional survey from January to May 2019 in three Indian sites: Valsad, Gujarat (western India); Nilgiris, Tamil Nadu (south India); and East Khasi Hills district of Meghalaya (north-east India) on 623 indigenous tribal adolescents.

Results:

Aggregate prevalence of any psychiatric morbidity was 15.9% (95% CI: 13.1–19.0) (males: 13.6%, 95% CI: 10.0–18.1; females: 17.9%, 95% CI: 13.9–22.6), with site-wise statistically significant differences: Gujarat: 23.8% (95% CI: 18.1–30.2), Meghalaya: 17.1% (95% CI: 12.4–22.7), Tamil Nadu: 6.2% (95% CI: 3.2–10.5). The prevalence of diagnostic groups was mood disorders 6.4% ( n = 40), neurotic- and stress-related disorders 9.1% ( n = 57), phobic anxiety disorder 6.3% ( n = 39), AUD 2.7% ( n = 17), behavioral and emotional disorders 2.7% ( n = 17), and obsessive-compulsive disorder 2.2% ( n = 14). These differed across the sites.

Conclusion:

The prevalence of psychiatric morbidity in adolescent tribals is approximately twice the national average. The most common psychiatric morbidities reported are mood (affective) disorders, neurotic- and stress-related disorders, phobic anxiety disorder, AUD, behavioral and emotional disorders, andobsessive-compulsive disorder.
Impact of social Media usage on technostress and cyber incivility
Authors: Mert İbrahim Sani , Şen Cem , Abubakar A Mohammed
Published: October 2023

Social media has become omnipresent in our personal and work lives; it is addictive and distracting. Its distractive nature can have adverse effects on an individual's behavior. To provide more insight into how technology influences various aspects of our social lives, this article draws on Social Exchange and Cognitive Theories as well as the Transactional Theory of Stress to investigate the potential impact of social media usage on technostress and cyber incivility, and the mediating role of technostress. The study adopted Partial Least Squares Structural Equation Modeling (PLS-SEM) on survey data obtained from (n = 324) lawyers. Results revealed that social media usage is a strong predictor for both technostress and cyber incivility of others (observed by the lawyers). Technostress also emerges as a key predictor for cyber incivility, and technostress mediates the link between social media usage and cyber incivility. The take home message for managers in the legal sector is the necessity of promoting awareness of excessive and uncontrolled usage of social media, as greater level of awareness will help to desensitize lawyers’ susceptibility to technostress and perception of cyber incivility of others. Implications for theory and practice alongside limitations are discussed.

Published: October 2023

Introduction

Prone position ventilation (PPV) of patients with adult respiratory distress syndrome (ARDS) supported with veno-venous extracorporeal membrane oxygenation (V-V ECMO) may improve oxygenation and alveolar recruitment and is recommended when extensive dorsal consolidations are present, but only few data regarding adverse events (AE) related to PPV in this group of patients have been published.

Methods

Nationwide retrospective analysis of 68 COVID-19 patients admitted from March 2020 – December 2021 with severe ARDS and need of V-V ECMO support. The number of patients treated with PPV, number of PPV-events, timing, the time spent in prone position, number and causes of AE are reported. Causes to stop the PPV regimen and risk factors for AE were explored.

Results

44 out of 68 patients were treated with PPV, and 220 PPV events are evaluated. AE were identified in 99 out of 220 (45%) PPV events and occurred among 31 patients (71%). 1 fatal PPV related AE was registered. Acute supination occurred in 19 events (9%). Causes to stop the PPV regimen were almost equally distributed between effect (weaned from ECMO), no effect, death (of other reasons) and AE. Frequent causes of AE were pressures sores and ulcers, hypoxia, airway related and ECMO circuit related. Most AE occurred during patients first or second PPV event.

Conclusions

PPV treatment was found to carry a high incidence of PPV related AE in these patients. Causes and preventive measures to reduce occurrence of PPV related AE during V-V ECMO support need further exploration.
Environmental Policies and the Promotion of Pro-Environmental Consumer Behavior: A Systematic Literature Review
Authors: Pham Hanh N. , Thai Nguyen T. , Heffernan Troy William , Reynolds Nina
Published: October 2023

Governments and policymakers play a crucial role in promoting consumer behaviors to mitigate climate change. The research on environmental policies over the past decades has not significantly increased knowledge regarding how effectively these policies help consumers embrace pro-environmental behaviors. Using the motivation–opportunity–ability (MOA) framework, this systematic review reveals that regulatory policies that constrain opportunities are more likely to promote pro-environmental behavior. Furthermore, economic policy instruments that facilitate opportunities are also more likely to promote pro-environmental behaviors. Despite being more commonly employed, informational policy instruments are less effective than regulatory and economic instruments. Although informational policy instruments that target opportunities instead of motivations and abilities can result in better outcomes, behavior change remains a challenge. This systematic review is significant because it clarifies mixed results in the literature regarding the effectiveness of environmental policies in promoting pro-environmental behaviors. Accordingly, a framework of MOA-based policy mix is proposed to help policymakers develop effective instruments that stimulate pro-environmental behaviors.
3D multi-scale feature extraction and recalibration network for spinal structure and lesion segmentation
Authors: Wang Hongjie , Chen Yingjin , Jiang Tao , Bian Huwei , Shen Xing
Published: October 2023

Background

Automatic segmentation has emerged as a promising technique for the diagnosis of spinal conditions.

Purpose

To design and evaluate a deep convolution network for segmenting the intervertebral disc, spinal canal, facet joint, and herniated disk on magnetic resonance imaging (MRI) scans.

Material and Methods

MRI scans of 70 patients with disc herniation were gathered and manually annotated by radiologists. A novel deep neural network was developed, comprising 3D squeeze-and-excitation blocks and multi-scale feature extraction blocks for automated segmentation of spinal structure and lesion. To address the issue of class imbalance, a weighted cross-entropy loss was introduced for training. In addition, semi-supervision segmentation was accomplished to reduce annotation labor cost.

Results

The proposed model achieved 77.67% mean intersection over union, with 9.56% and 11.11% gains over typical V-Net and U-Net respectively, outperforming the other models in ablation experiments. In addition, the semi-supervision segmentation method was proven to work.

Conclusion

The 3D multi-scale feature extraction and recalibration network achieved an excellent segmentation performance of intervertebral disc, spinal canal, facet joint, and herniated disk, outperforming typical encoder-decoder networks.
Impact of 3D-printed laboratory equipment in vibrations and controls courses on student engineering identity, motivation, and mindset
Authors: Utschig Tris , Tekes Ayse , Linden Maureen
Published: October 2023

This paper describes the implementation of innovative 3D-printed laboratory equipment linked to inquiry-based learning activities designed to improve learning, increase engineering identity and motivation, and foster a growth mindset in students taking undergraduate level mechanical vibrations courses, control theory courses, and associated laboratories. These innovative designs create new opportunities for hands-on learning, are low-cost, portable, and can be adapted for use in multiple science and engineering disciplines. The learning activities are based on the POGIL model, which has been used across a variety of disciplines including engineering. We describe the features of three separate devices (spring-connected sliding carts, compliant parallel arms with fixed-free ends and a slider mass, and a pendulum with variable tip load) implemented using a quasi-experimental approach with 510 duplicated students across three semesters during the COVID-19 pandemic in multiple lecture courses and laboratory sections. We also present an assessment of impact based on descriptive statistical analyses of survey data for student-reported learning gains and pre-post paired comparison tests on validated instruments measuring perceptions of engineering identity, engineering motivation, and growth mindset. Further, we conducted a student focus group and include salient instructor observations. Results show most students participating in the learning activities using these devices report that it supported their learning “a lot” or “a great deal.” In addition, on six of seven surveyed learning outcomes, most students reported feeling confident enough to complete them on their own or even teach them to someone else. Our data did not show a measurable impact on engineering identity, engineering motivation, or growth mindset, though it does suggest further investigation is merited.

Transitioning From Introductory to Professional Programming in Secondary Education: Comparing Learners’ Computational Thinking Skills, Behaviors, and Attitudes
Authors: Sun Dan , Zhu Chengcong , Xu Fan , Li Yan , Ouyang Fan , Cheng Miaoting
Published: October 2023

Although previous research has provided some insights into the effects of block-based and text-based programming modalities, there is a dearth of a detailed, multi-dimensional analysis of the transition process from different introductory programming modalities to professional programming learning. This study employed a quasi-experimental design to address this gap, involving 64 secondary school students in two groups. For the beginning five weeks, the first group used an introductory block-based programming environment, while the second group used an introductory text-based programming environment. Then, both groups transitioned to professional text-based programming for the subsequent eight weeks. The results showed that participants who transitioned from introductory text-based programming to professional text-based programming (1) significantly outperformed in computational thinking skills; (2) had more code-writing and debugging behaviors and fewer irrelevant behaviors, and (3) had more interactions with the instructor. No significant differences were observed between the two groups regarding enjoyment, confidence, and interest in programming. Drawing on these findings, this study proposes pedagogical implications that could facilitate the adoption of programming modalities within the broader context of STEM education.
“It is Essentially About Treating Each Other Well”: Insights from Faculty on Incivility in Nursing Education
Authors: Small Sandra P. , Cashin Geraldine , English Denise , Moran Glenys
Published: October 2023

Study background

Incivility in nursing educational institutions, which may be perpetrated by both students and faculty, is troubling given that such institutions have a mandate to prepare students for caring, relational nursing practice.

Purpose

The purpose of this study was to contribute to understanding nursing academic incivility through an examination of nursing faculty's perspectives on student and faculty incivility.

Methods

The study was conducted using a mixed methods, descriptive, survey design with collection and analysis of quantitative and qualitative data. The sample consisted of 52 faculty members.

Results

A large majority of faculty thought that incivility in the nursing academic environment is a problem, with most considering it to be a mild or moderate problem. Students acted unprofessionally by showing disrespect, displaying superiority, engaging in disruptive behaviors, or not taking responsibility for their role in their learning. Faculty acted unprofessionally by showing disrespect, displaying superiority, or not being supportive. Faculty perceived that stress, personality, failure to deal with incivility, and an attitude of entitlement contributed to incivility. They thought that educational interventions, policies, and an academic environment that is conducive to civility are needed to address the problem.

Conclusion

Until evidence is available to support the effectiveness of interventions for academic incivility, nursing educational institutions are encouraged to implement strategies suggested by faculty in this study.

Nurse researchers can incorporate recommendations into study protocols and procedures to identify and address unmet needs of this population.
Temperature Control in the Era of Personalized Medicine: Knowledge Gaps, Research Priorities, and Future Directions
Authors: Beekman Rachel , Khosla Akhil , Buckley Ryan , Honiden Shyoko , Gilmore Emily J.
Published: October 2023

Hypoxic–ischemic brain injury (HIBI) is the leading cause of death and disability after cardiac arrest. To date, temperature control is the only intervention shown to improve neurologic outcomes in patients with HIBI. Despite robust preclinical evidence supporting hypothermia as neuroprotective therapy after cardiac arrest, there remains clinical equipoise regarding optimal core temperature, therapeutic window, and duration of therapy. Current guidelines recommend continuous temperature monitoring and active fever prevention for at least 72 h and additionally note insufficient evidence regarding temperature control targeting 32 °C-36 °C. However, population-based thresholds may be inadequate to support the metabolic demands of ischemic, reperfused, and dysregulated tissue. Promoting a more personalized approach with individualized targets has the potential to further improve outcomes. This review will analyze current knowledge and evidence, address research priorities, explore the components of high-quality temperature control, and define critical future steps that are needed to advance patient-centered care for cardiac arrest survivors.
Explaining interactions in collaborative innovation arrangements: How organizations influence their representatives’ interactions in collaborative innovation arrangements
Authors: Langbroek Tom , Verhoest Koen
Published: October 2023

Innovation through collaboration has been increasingly adopted to tackle complex social issues. As a result, the development of public sector innovations is to a lesser degree an ‘in-house’ matter and public sector innovations are increasingly more developed in collaborative arrangements that force organizations to interact across organizational borders. Despite the growing body of literature on collaborative innovation, little is known about the influence of organizations on the interactions of their members when they are acting on behalf of their organization in such collaborative arrangements. Through social network analysis, we examine how organizations influence the eagerness of their representatives in arrangements for collaborative innovation to engage in interactions outside official meetings with other participants. We found that the representative’s freedom to act and the extent to which the higher-level managers of the own organization sees the innovation project as a priority stimulates the extent to which the representative interacts with other participants in the arrangement. Moreover, reciprocity and having a coordinating role in the process determines interaction as well.
Microbial production of zeaxanthin from algal biomass and waste glycerol using a newly isolated agarolytic marine bacterium Cellulophaga omnivescoria MSK1
Authors: Kim Min Sun , Jeong Sun-Wook , Yang Jung Eun , Choi Yong Jun
Published: October 2023

With increasing interests in the biological conversion of waste resources into value-added chemicals and biocompounds, algal biomass has emerged as a promising renewable feedstock due to abundance, rapid growth, and sustainability. However, efficient bioconversion method is still being challenged due to the lack of suitable host strain capable of directly utilizing algal biomass and converting into desired products. In this study, a potent marine bacterium capable of producing zeaxanthin from algal biomass was investigated. The agarolytic bacterium, Cellulophaga omnivescoria MSK1 was isolated from coastal seawater. Through physiological and morphological analysis, it was confirmed that this bacterium degrade agarose into neoagarotetraose (NA4) and neoagarohexaose (NA6) and produces zeaxanthin using agarose as a carbon source. This bacterial strain demonstrated the ability to produce 2.23 ± 0.19 mg/L of zeaxanthin when provided with 0.2% agarose as a carbon source. By supplementing with glycerol, zeaxanthin production was further enhanced, reaching levels of 8.43 ± 0.31 mg/L, with a content of 6.77 ± 0.3 mg/g CDW (cell dry weight). These results suggest that an agarolytic Cellulophaga omnivescoria MSK1 strain has a great potential to be used as a platform microbial strain capable of producing zeaxanthin from algal biomass as a sustainable feedstock.
Maternal and fetal health outcomes in systemic lupus erythematosus pregnancies in the Emirati population: A comparative study
Authors: Khogali Hiba I , Al‐Bluwi Ghada S M , Guy Pedo Virgie , Al Dhanhani Ali M
Published: October 2023

Objectives

To evaluate adverse pregnancy outcomes in patients with systemic lupus erythematosus (SLE), compare their maternal and fetal outcomes with those of age-matched pregnant women without SLE, and identify factors linked to increased risks of adverse outcomes.

Methods

Medical records from Tawam Hospital were reviewed retrospectively to identify patients with SLE and a history of pregnancy. Demographics, clinical variables, and maternal and fetal outcomes were obtained. A one-to-one age-matched healthy control group was randomly selected. The outcomes and odd ratios of women with and without SLE were compared, and factors associated with adverse pregnancy outcomes were examined.

Results

The outcomes of 78 SLE pregnancies in 39 women were analyzed. Adverse maternal outcomes, such as gestational diabetes mellitus (GDM), occurred in 32% of pregnancies, whereas adverse fetal outcomes, such as low-birth weight and preterm deliveries, occurred in 51% of pregnancies. Pregnant women with SLE had a 5-fold higher risk of GDM, had higher odds of maternal hypertension, and were more likely to deliver through cesarean section than those without SLE. Preterm deliveries and low-birth weight were also more common in SLE pregnancies. Steroid use during pregnancy was significantly associated with an increased risk of GDM development. Lupus nephritis, maternal hypertension, pre-eclampsia, and GDM were linked to preterm deliveries.

Conclusion

Pregnant women with SLE were at a higher risk for adverse maternal and fetal outcomes than age-matched pregnant women without SLE. These findings can guide clinical management and emphasize the need for close monitoring of SLE pregnancies.
Teaching for Global Citizenship Education Online: An African Philosophical Approach
Authors: Waghid Yusef
Published: October 2023

Global citizenship education (GCE) has been in vogue for the last decade. The term has been used mostly to espouse and rearticulate some of the democratic, responsible and activist aspirations linked to forms of transformative higher education (HE) in the world today. Southern African HE is no exception, particularly invoking some of the (post)critical and decolonial virtues within matrices of HE for change. In this article, it is described how reflections on a massive open online course brought to the fore several poignant moments in the pursuit of cultivating a (post)critical and decolonial notion of GCE. Such reflections focused on enacting an African philosophy of HE, particularly showing how, first, ukama (iterative action) can be used to engage humans in perspicuous and deliberative ways; second, ubuntu (critical and dissonant action) is drawn upon to show how agreement and dissent about educational and societal matters can be resolved; and third, the notion of umsibenzi (activism) is couched in moderate terms to emphasise the potentiality and impotentiality of action that could subvert societal dystopias on the African continent and elsewhere. In this way, the cultivation of an African philosophy of HE could broaden the notion of a (post)critical and decolonial understanding of GCE.
Collective Sensemaking: Training the Leadership-as-Practice Development Trainer for Adult Leadership Learning
Authors: Kliewer Brandon W.
Published: October 2023

A gap often exists between adult leadership learning and development practice. This gap seems particularly pronounced when considering training through a collective, practice, and constructionist theoretical lens. Leadership developers need to address this gap in their teaching methods if they are to support learning capable of responding to Complex Adaptive System (CAS) challenges. Drawing from a case-in-point (CIP) train-the-trainer experience hosted by the Kansas Leadership Center (KLC) this study will help trainers understand how primary and keying frames can be used to analyze how facilitators train trainers to use collective sensemaking for adult leadership learning. The case-in-point leadership development method is capable of moving adult leadership learners to make more systemic interpretations of leadership challenges and collectively interrogate cultural assumptions and identity.
Impact of the COVID-19 Public Health Crisis and a Structured COVID Unit on Physician Behaviors in Code Status Ordering
Authors: Molitch-Hou Ethan , Zhang Hui , Gala Pooja , Tate Alexandra
Published: October 2023

Purpose: Code status orders are standard practice impacting end-of-life care for individuals. This study reviews the impact of a COVID unit on physician behaviors towards goal-concordant end-of-life care at an urban academic tertiary-care hospital. Methods: We conducted a retrospective cohort study of code status ordering on adult inpatients comparing the pre-pandemic period to patients who tested positive, negative and were not tested during the pandemic from January 1, 2019, to December 31, 2020. Results: We analyzed 59,471 unique patient encounters (n = 35,317 pre-pandemic and n = 24,154 during). 1,631 cases of COVID-19 were seen. The rate of code status orders among all inpatients increased from 22% pre-pandemic to 29% during the pandemic ( P < .001). Code status orders increased for both patients who were COVID-negative (32% P < .001) and COVID-positive (65% P < .001). Being in a cohorted COVID unit increased code status ordering by an odds of 4.79 ( P < .001). Compared to the pre-pandemic cohort, the COVID-positive cohort is less female (50% to 56% P < .001), more Black (66% to 61% P < .001), more Hispanic (6.5% to 5%) and less white (26% to 30% P < .001). Compared to Black patients, white patients had lower odds (.86) of code status ordering ( P < .001). Other race/ethnicity categories were not significant. Conclusions: Code status ordering remains low. Compared to pre-pandemic rates, the frequency of orders placed significantly increased for all patients during the pandemic. The largest increase occurred in patients with COVID-19. This increase likely occurred due to protocols in the COVID unit and disease uncertainty.
Patterns of Repetition, Intermittency, and Harm Escalation in Same-Sex and Mixed-Sex Intimate Partner Violence: An Analysis of 1,000 Days of National Police Records in Sweden
Authors: Dagenbrink Marika , Bland Matthew , Ariel Barak
Published: October 2023

In recent years more attention has been given to the ways in which mixed-sex and same-sex intimate partner violence (IPV) couples report crimes to the police. Specifically, what patterns of repetition, intermittency between contacts with the police, and harm trajectories over time exist, and are there variations between same-sex and mixed-sex dyads? We explore all eligible IPV reported in Sweden over 1,000 days ( n = 14,939) and use descriptive statistics to examine differences between different victims and offenders. We code IPV offences within three levels of harm recognized by law and develop a tiered approach to harm quantification that supports the growing evidence that not all IPV harm is the same. Based on official records, IPV usually ends following the first contact with the police, as nine out of ten dyads never call again. Variations across cisgender and sexual identity groups exist: Repeat same-sex IPV is not as common as mixed-sex IPV but is reported more quickly to the police after it had occurred once. In the 1,000-day follow-up period, same-sex dyads do not call the police more than four times and the repeated incidents trends seem to be driven primarily by outliers. Moreover, we find an overall pattern of decreasing time intervals between each additional contact, but no overall pattern of escalating severity over time. However, the overall severity trend it driven by female-victim-male-offender dyads: male offenders are more likely to cause escalation of harm, while two out of five male–male repeat IPV experience escalation in harm. We discuss the theoretical and practical implications of these findings, which overall illustrate the importance of observing IPV in typological terms, rather than as a continuum.

A new method for reducing the number of resonance frequencies of mechanical systems within a specified frequency range with inverse structural modification and pole-zero cancellation
Authors: Şen Murat , Çakar Orhan
Published: October 2023

Resonance frequencies of a mechanical system are the most important parameters that determine the dynamic characteristics of the system. When the frequencies of the harmonic forces under the influence of the system coincide with the resonance (natural) frequencies of the system, a resonance situation occurs and the mechanical system vibrates with high amplitudes. This can cause serious damage to the system by causing effects such as break, fatigue, impact, noise on the bearings, connections and elements in the system. It is possible to eliminate some resonance frequencies of mechanical systems in an examined frequency range using pole-zero cancellation methods by shifting a resonance frequency of the system to an anti-resonance frequency or an anti-resonance frequency to a resonance frequency. Thus, a solution can be obtained for some vibration problems. In this study, a new method using the Sherman-Morrison formula is presented to eliminate some of the resonance frequencies for some FRFs (Frequency Response Functions) of mechanical systems with pole-zero cancellation. In order to eliminate a selected resonance frequency of the system in any FRF determined using the presented method, a mass (kg) and a grounded spring (N/m) modification are made and the required modification values for this are calculated by solving the obtained non-linear equation set numerically. With the proposed method, it is aimed to contribute to the literature by presenting an alternative approach for the solution of vibration problems by cancelling some selected resonance frequencies. The main highlight of the method is there is no need of a matrix inversion for calculating the required modification values. This provides a very fast solution. In addition, the proposed method uses directly the FRFs of the active coordinates (response, excitation and modification) only, which makes the method very useful for practical engineering applications.
Insights on Engaging Men and Boys in Creating a More Gender Equal Future in Canada

Published: October 2023

This article presents findings from a national qualitative research study of 33 diverse and profeminist leaders who identify as men and are engaged in gender equality work with men and boys across Canada. Key findings include the need to meet men where they are at, moving away from the ineffective “all men are perpetrators” frame, and to evolve to new and more relatable narratives and approaches that get men committed to this work for their own liberation. Taking an intersectional approach and working in partnership with feminist and intersectional organizations are essential to advancing gender equality in the Canadian context.

There is limited research that specifically explores paternal involvement during pregnancy and childbirth. To address this gap, we completed a series of focus groups with fathers to examine social, cultural, and environmental factors that influence behaviors among new fathers while also providing community perspectives on men’s experiences seeking care pre- and postdelivery. We used a phenomenological thematic approach to analyze data from 10 focus groups from five of the six Alliance for Innovation on Maternal Health-Community Care Initiative pilot sites collected between November 2021 and April 2022. The average age of fathers was 33.9 years (range = 24–61 years). The majority (86.25%) of men were African American, and approximately one sixth of focus group participants (16.25%) were Hispanic or Latino. Four key themes emerged: the importance and meaning of fatherhood, accessibility during pregnancy and childbirth, engagement during pregnancy and childbirth, and responsibility of fathers during pregnancy and childbirth. These fathers not only understood and embraced the awesome responsibility they had for their unborn child, but they also recognized and were invested in being present, accessible, engaged, and responsible to the pregnant woman during the pregnancy. Practitioners and policy makers should work to engage fathers as early in the pregnancy as possible; monitor father’s mental health and financial stress; provide resources to educate fathers on maternal health, pregnancy, and childbirth; and emphasize fathers’ rights, roles, and responsibilities.

When the hydrostatic thrust bearings operate under conditions of high speed and heavy load, the oil film will be strongly sheared and squeezed, which will increase the temperature of the hydrostatic oil film, resulting in uneven deformation of the workbench and tribology in serious cases. The deformation of the friction pair greatly affects the stability of the workbench during operation, and then affects the machining accuracy. Taking the hydrostatic thrust bearings as the research object, the model of hydrostatic thrust bearings was established based on the fluid–thermosolid coupling theory, and the influencing factors of the deformation of the hydrostatic thrust bearings are analyzed using ANSYS Workbench software, and the influencing laws are discussed. Finally, the correctness of the simulation method is verified by experiments. The results show that the larger the lubricating oil viscosity, the greater the deformation of the guide surface and the oil pad. With the increase in the rotation rate, the deformation of the guide surface and the oil pad increases continuously. With the increase in the inlet flow rate, the deformation of the guide surface and the oil pad is continuously reduced. In engineering practice, on the premise of ensuring the bearings capacity, low-viscosity lubricating oil should be used as much as possible, the rotation rate should be lower, or the inlet flow rate should be increased.
