Who Can Benefit More From More or Less Elaborated Feedback in a Computer-Based Assessment? Dominant Goal Orientation Matters
Authors: Wang Zhen , Cao Yang , Gong Shaoying
Published: October 2022

Although learner characteristics have been identified as important moderator variables for feedback effectiveness, the question of why learners benefit differently from feedback has only received limited attention. In this study, we investigated: (1) whether learners’ dominant goal orientation moderated the effects of computer-based elaborated feedback on learning; and (2) whether learners’ feedback perception and learning motivation mediated the relationship between elaborated feedback and learning performance. To answer these questions, 101 undergraduates with dominant learning or performance goals were randomly exposed to cue feedback or explanation feedback while working on psychological statistics tasks in a computer-based assessment. Results revealed the moderation role of dominant goal orientation in the relations between elaborated feedback and learning. Specifically, elaborated feedback had more positive effects on dominant learning-oriented learners, but no effects on dominant performance-oriented learners. In addition, feedback perception mediated the moderating effect of dominant goal orientation on the relationship between elaborated feedback and transfer performance. These findings contribute to a better understanding of the role of goal orientations in feedback learning.

Authors: Sivanesan Umaseh , Wu Kay , McInnes Matthew D. F. , Dhindsa Kiret , Salehi Fateme , van der Pol Christian B.
Published: October 2022

Purpose: To establish reporting adherence to the Checklist for Artificial Intelligence in Medical Imaging (CLAIM) in diagnostic accuracy AI studies with the highest Altmetric Attention Scores (AAS), and to compare completeness of reporting between peer-reviewed manuscripts and preprints. Methods: MEDLINE, EMBASE, arXiv, bioRxiv, and medRxiv were retrospectively searched for 100 diagnostic accuracy medical imaging AI studies in peer-reviewed journals and preprint platforms with the highest AAS since the release of CLAIM to June 24, 2021. Studies were evaluated for adherence to the 42-item CLAIM checklist with comparison between peer-reviewed manuscripts and preprints. The impact of additional factors was explored including body region, models on COVID-19 diagnosis and journal impact factor. Results: Median CLAIM adherence was 48% (20/42). The median CLAIM score of manuscripts published in peer-reviewed journals was higher than preprints, 57% (24/42) vs 40% (16/42), P < .0001. Chest radiology was the body region with the least complete reporting ( P = .0352), with manuscripts on COVID-19 less complete than others (43% vs 54%, P = .0002). For studies published in peer-reviewed journals with an impact factor, the CLAIM score correlated with impact factor, rho = 0.43, P = .0040. Completeness of reporting based on CLAIM score had a positive correlation with a study’s AAS, rho = 0.68, P < .0001. Conclusions: Overall reporting adherence to CLAIM is low in imaging diagnostic accuracy AI studies with the highest AAS, with preprints reporting fewer study details than peer-reviewed manuscripts. Improved CLAIM adherence could promote adoption of AI into clinical practice and facilitate investigators building upon prior works.
A Network Analysis of the Relationship Between Mental and Physical Health in Unsheltered Homeless Persons in Los Angeles County
Authors: Barboza-Salerno Gia Elise , Kosloski Anna , Weir Henriikka , Thompson Dywane , Bukreyev Alexey
Published: October 2022

Homelessness is a public health crisis both nationally, in the United States, and internationally. Nevertheless, due to the hidden vulnerabilities of persons who are without shelter, little is known about their experiences during periods of homelessness. The present research adopts a network approach that conceptualizes how the major risk factors of homelessness interact, namely substance abuse problems, poor mental health, disability, and exposure to physical or sexual violence by an intimate partner. Our analysis draws on a large demographic survey of over 5,000 unsheltered homeless persons conducted in 2017 by the Los Angeles Homeless Services Authority. We estimated a network structure for 12 survey items tapping individual risk using the graphical least absolute shrinkage and selection operator algorithm. We then examined network centrality metrics and implemented a community detection algorithm to detect communities in the network. Our results indicated that mental illness and intimate partner violence (IPV) are central measures that connect all other mental and physical health variables together and that post-traumatic stress disorder and IPV are both highly affected by changes in any part of the network and, in turn, affect changes in other parts of the network. A community detection analysis derived four communities characterized by disability, sexual victimization and health, substance use, and mental health issues. Finally, a directed acyclic graph revealed that drug abuse and physical disability were key drivers of the overall system. We conclude with a discussion of the major implications of our findings and suggest how our results might inform programs aimed at homelessness prevention and intervention.
Investigation of microstructure, mechanical properties, and wear behavior of aluminum A380 nanocomposite reinforced with graphene nanosheets produced by spark plasma sintering technique
Authors: Sajjadpour Haniyeh , Alipour Mohammad
Published: October 2022

The study reports the development of graphene nanosheets reinforced aluminum A380 matrix nanocomposites using powder metallurgy. Nanocomposites are fabricated by a mechanical alloying process and the bulk nanocomposites are prepared by spark plasma sintering (SPS) technique in a vacuum at 540 °C. 0.25 wt%, 0.5 wt%, 0.75 wt%, and 1 wt% of graphene nanosheets are used as a refinement for nanocomposites. Microstructural, mechanical properties, and wear behavior of the Al A380–graphene nanocomposites were investigated. Testing and analysis of fabricated composites revealed an improvement in hardness (59.96%) and wear rate (108.57%). Grain refinement action caused by graphene, high hardness, and graphene's self-lubricating nature is reasoned for these improvements. Optical microscopy and scanning electron microscopy (SEM) analysis were used to investigate microstructures of the nanoparticle distribution in the nanocomposites of the SPS samples. The wear resistance of resultant composites is reported at a higher side, decreasing friction coefficient owing to graphene's self-lubricating nature. Moreover, the incorporation of lubricant graphene nanosheets significantly reduced the wear rate and the friction coefficient in comparison with the Al A380 matrix composites. Wear morphology is characterized using SEM. In the end, the Al A380–0.5% graphene nanocomposite sample represents the greatest hardness and wear behavior, and good microstructure to compare with the other experimented samples.
Navigating feminist and biomedical conceptual frameworks in educational interventions for eating disorders: Spanish educators’ understandings of the causes and treatment of eating disorders
Authors: García-Ruiz María , Padilla-Petry Paulo
Published: October 2022

The biomedical view of eating disorders (EDs) dominates in their classification and treatment regardless of the importance of sociocultural factors in EDs. Critical feminist approaches to EDs try to relate them to oppressive situations, disempowerment and the construction of gender. Educational interventions with people with EDs may be an alternative to biomedical approaches, giving them opportunities to tell their stories, listen to themselves and take control of their lives. This article presents a thematic analysis of semi-structured interviews with professionals who carry out educational interventions for people with EDs. Findings show that the biomedical description and treatment of EDs remain unchallenged and recognising client voice may be a problem, even in educational interventions. Also, the potential negative consequences of the rigid control of the clients’ lives seem to be ignored. Feminist approaches to EDs are acknowledged but do not seem to guide any intervention. Sociocultural critical stances that would recognise the coherence or the transitions between what is considered as healthy and sick eating also seem to be lacking.
Implications of sea level variability on the formation and evolution of subtropical Rainbow Beach patterned fen complexes, Queensland, Australia
Authors: Hanson Johanna M , Welsh Kevin J , Moss Patrick T , Gadd Patricia
Published: October 2022

The Great Sandy National Park [K’gari (Fraser Island) and Cooloola] contains the largest subtropical patterned fen complexes in the world. These globally significant, groundwater-dependent ecosystems have been previously studied in relatively undisturbed areas on K’gari and were suggested to be resilient to changes in hydrology, sea level and wildfires. The Rainbow Beach patterned fens are under-studied systems thought to be formed in local perched aquifers. The palaeoenvironmental conditions required for the formation and continuation of these peatlands, and how they react to changes in hydroclimate, sea level and human activities are uncertain. We attempt to resolve this ambiguity using proxies for vegetation and environmental changes over the last ~12,770 cal yr BP from a sediment core located in the Rainbow Beach patterned fen complex. We infer the formation of an aquitard layer and Empodisma minus mire development at ~12,770 cal yr BP, with conditions conducive for patterning ~12,000–10,000 cal yr BP. Paludification occurred in the early Holocene, coincident with increased sea levels, which expanded the mire inland. Increased salt marsh taxa during this period coincides with decreased E. minus values, while further peatland development occurred ~4200 cal yr BP, suggesting that marine influences greatly effect these coastal peatlands. Evidence of vegetation thickening associated with post-European fire suppression was observed. Compared to those on K’gari, the Rainbow Beach complex appears to have initiated through different processes and show greater sensitivity to changes in sea levels. Therefore, subtropical patterned fens should be assessed independently to identify individual trajectories and sensitivities.
Exposure to pesticides and pediatric Wilms’ tumor. A meta-analysis on pre-conception and pregnancy parental exposure with an IARC/WHO commentary
Authors: Khan A , Feulefack J , Sergi CM
Published: October 2022

Background

There are hereditary types of nephroblastoma or Wilms’ tumor associated with exposure of the germ cells of either parent to harmful environmental factors. Some studies have examined the exposure of compounds used pesticides and herbicides as a risk factor for Wilms’ tumor.

Methods

A systematic review and meta-analysis were carried out on case-control studies to establish the potential link between exposure to these organic molecules and Wilms’ tumor occurrence in children rigorously. We examined the monographs on some organo-phosphate insecticides and herbicides issued by the International Association for the Research on Cancer (IARC) under the auspices of the World Health Organization (WHO). PUBMED, SCOPUS, and Google Scholar studies (1960–2021) were identified and systematically reviewed following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Subgroup analyses were conducted after stratification for occupational versus residential exposure and before birth (prenatal) vs. after birth (postnatal) exposure. In addition, we revised the monographs on chemical compounds issued recently by the IARC/WHO.

Results

Our findings seem to consolidate that parental pesticide exposure during the preconception or pregnancy period is correlated with an increased occurrence risk for Wilms’ tumor. We confirm the validity of the WHO essays on certain organophosphate herbicides and insecticides, which support these compounds, may be highly relevant in future cancer prevention policies.

Conclusion

Parental exposure to pesticides, particularly in household settings, is poorly emphasized in our society. There is a strong association between these organophosphate compounds and pediatric cancer. Public health agencies may need to take stronger action than in the past.

Published: October 2022

Carotid artery thrombosis following carotidynia is an uncommon manifestation of systemic lupus erythematosus. We report the case of a woman without evidence of a lupus flare-up who presented with the unusual clinical course of ipsilateral carotidynia and recurrent ischemic stroke due to carotid thrombosis. To our knowledge, this is the first case of such an unusual manifestation in lupus and highlights distinctive challenges in the diagnosis and management of carotid artery thrombosis following carotidynia.
Familial Esophageal Cancer in Taihang Mountain, China: An Era of Personalized Medicine Based on Family and Population Perspective
Authors: Zheng Yuanyuan , Niu Xiaoyu , Wei Qian , Li Yijing , Li Lifeng , Zhao Jie
Published: October 2022

In the Taihang Mountain areas, known as the “esophageal cancer zone” in China, the incidence of esophageal cancer (ESCA) ranks the first in the country and shows a familial and regional clustering trend. Taihang Mountain areas are located in a mountainous area, with inconvenient transportation, limited living conditions, unbalanced diet, and poor nutrition. Ninety percent of the pathological types of ESCA in Taihang Mountain areas are squamous cell carcinoma, among which the risk factors have not been well understood. These areas are usually remote villages and mountains with low population mobility, large family members, similar environmental factors, and a clear and stable genetic background. Therefore, according to the current situation, second-generation sequencing and multigroup analysis technology are used to analyze the familial ESCA patients; disease-related genetic variation are located; and then disease-related susceptibility genes associated with ESCA are screened and analyzed. Health education, tobacco control, endoscopic screening, and other health management projects for suspected and high-risk patients in areas with a high incidence of ESCA can be carried out for screening and early diagnosis, and the incidence of ESCA in Taihang Mountain areas can be reduced. A comprehensive continuous care pattern based on traditional medical nursing to track, monitor, evaluate, and intervene with patients diagnosed with ESCA to facilitate them with medications guidance, dietary guidance, and timely health problem-solving is established. Furthermore, statistical analysis of epidemiology, gene sequencing, and family genetics information can be performed on patients with ESCA in the Taihang Mountains areas to clarify the relationship between genetic phenotype and genotype during the occurrence of ESCA.
The Impact of Internet Banking on Performance and Branches: Crisis or Change in Practice?
Authors: Di Febo Elisa , Angelini Eliana
Published: October 2022

Internet Banking has become an important alternative to traditional banks. This article studies how Internet Banking’s use influenced European banks’ profitability and if the phenomenon of the branches’ strong contraction (started in 2009 and consolidated from 2011 to 2016) depended on using these technologies or the economic crisis of the period. The exclusion of the COVID-19 crisis derived from the voluntariness to analyze the branches’ reduction in your primitive form and not as a consequence of the event’s extreme.

The sample data comprises 3679 European banks from 2011 to 2016. The methodology used is the instrumental variables. This approach can control internal validity threats, such as confounding variables, measurement error, spuriousness, simultaneity and reverse causality.

The results show that Internet Banking has positively influenced the net interest income and negatively affected the distribution of the branches, justifying the strong reduction. Surprisingly, the insignificance of GDP rates on the branch network, while the strong European prudential regulation had a negative impact.

The study of Internet Banking’s impact on the branches is a new aspect and important for further developments. As transactions are handled online, branch offices will become more like service lounges rather than rows of tellers handling daily transactions.
Restricted Variance Interactions in Entrepreneurship Research: A Unique Basis for Context-as-Moderator Hypotheses
Authors: Cortina Jose M. , Köhler Tine , Sheng Zitong , Keeler Kathleen R. , Nielsen Bo B. , Coombs Joseph E. , Ketchen David J.
Published: October 2022

In this methodological brief, we demonstrate the usefulness of the restricted variance (RV) interaction to entrepreneurship research. RV reasoning can help scholars to specify precise roles for contextual moderators. This specificity allows for strengthening of arguments and for testing of one of the reasons for an interaction. In some cases, it points to otherwise unexpected interaction patterns. We illustrate the power of RV reasoning with a data set of 503 biotech firms to show how RV explains geographic differences in the relationship between number of alliances and initial public offering value. Finally, we show how these interactions can be tested given typical distributions.
Waveform harmonic suppression technology for electromagnetic standard vibration actuators based on current feedback control
Authors: Li Wei , Cui Junning , Bian Xingyuan , Zou Limin
Published: October 2022

To realize high-precision calibration of vibration sensors, the total harmonic distortion (THD) of the output waveform of a standard vibration actuator should be as small as possible, so a harmonic suppression technique based on current feedback control is presented. A low-cost, easy-to-implement feedback control loop of driving current is established in an electromagnetic standard vibration actuator (EVA), and the rationality of driving current in place of acceleration in the acceleration characteristic frequency band to achieve the feedback is analyzed. The influence of different values of the key parameters on the system is studied, and the acceleration characteristic frequency band of low-frequency vibration is effectively extended so that the THD of the output waveform is immensely alleviated. The effectiveness of the proposed method is verified by experiments and compared with traditional control methods, the harmonic distortion of acceleration waveform can be reduced by more than 40% without using any feedback sensors, which proves the superiority of the current feedback control method.

Published: October 2022

Background:

Extracellular vesicles (EV) released from neurons into the blood can reflect the state of nervous tissue. Measurement of neuron derived EV (NDE) may serve as an indicator of brain injury.

Methods:

A sandwich immunoassay was established to measure plasma NDE using anti-neuron CD171 and anti-EV CD9 ([CD171 + CD9+]). Plasma samples were obtained from commercial sources, cross-country (n = 9), football (n = 22), soccer (n = 19), and rugby (n = 18) athletes over time. Plasma was also collected from patients undergoing total aortic arch replacement (TAR) with selective cerebral perfusion during cardiopulmonary bypass before and after surgery (n = 36).

Results:

The specificity, linearity, and reproducibility of NDE assay (measurement of [CD171 + CD9+]) were confirmed. By scanning electron microscopy and nanoparticle tracking, spherical vesicles ranging in size from 150 to 300 nm were confirmed. Plasma levels of NDE were widely spread over 2 to 3 logs in different individuals with a significant age-dependent decrease. However, NDE were very stable in each individual within a ± 50% change over time (cross-country, football, soccer), whereas rugby players were more variable over 4 years. In patients undergoing TAR, NDE increased rapidly in days post-surgery and were significantly ( P = .0004) higher in those developing postoperative delirium (POD) (n = 13) than non-delirium patients (n = 23).

Conclusions:

The blood test to determine plasma levels of NDE was established by a sandwich immunoassay using 2 antibodies against neuron (CD171) and exosomes (CD9). NDE levels varied widely in different individuals and decreased with age, indicating that NDE levels should be considered as a normalizer of NDE biomarker studies. However, NDE levels were stable over time in each individual, and increased rapidly after TAR with greater increases associated with patients developing POD. This assay may serve as a surrogate for evaluating and monitoring brain injuries.
Worker-led feminist mobilizing for the museum of the future
Authors: Middleton Margaret , Hagen Jamie J
Published: October 2022

Museum workers have taken a massive hit during the pandemic when many museums closed their doors, cut staff hours, instituted layoffs and furloughs, and pushed more into precarity. For many workers, the effect of the pandemic has highlighted long-standing issues of racial, economic, gender and political inequality. This article engages with how workers are responding to this insecurity by highlighting worker-led feminist mobilizations for transformation in museums based in the United States and the United Kingdom. By focusing on efforts for engaging with the Black Lives Matter movement, decolonizing the museum, unionizing workers and providing mutual aid, this article examines worker-led practices of transformation of the museum amid crisis. A special emphasis is put on how workers articulate the importance of feminist solidarity and collective action in envisioning a more just museum of the future.
Informal caregiver motivations, values, challenges and gains: A photovoice and interpretative phenomenological analysis of interrelationships
Authors: Zarzycki Mikołaj , Seddon Diane , Morrison Val
Published: October 2022

The adoption of a caregiving role in the context of illness and disability is often taken for granted. This study explores caregivers’ motivations to provide care and how these relate to values, and to the challenges and gains of caregiving. Eight semi-structured interviews were conducted with caregivers and photographs were taken by caregivers to exemplify their caregiving experiences. This photo-elicitation method complemented the use of Interpretative Phenomenological Analysis when applied to verbatim transcripts. Superordinate themes included: caregiver’s life story; significance of family; caregiving obligations; caring relationship; challenges and gains associated with caregiver motivations. Intrinsic and extrinsic motivations were less distinct in caregivers’ lived experiences than previously suggested, and were influenced by family values and specific challenges and gains of caregiving. The coexistence of different motivations and the nature of single complex motivations is discussed. The importance of caregiver assessment and support planning, and regular breaks from caregiving are highlighted.
A (queer) CEO society? Lesbians Who Tech and the politics of extra-ordinary homonormativity
Authors: Burchiellaro Olimpia
Published: October 2022

The article explores the queer politics of homo/anti-normativity of Lesbians Who Tech, a corporate network for lesbian and queer women. Drawing from ethnographic fieldwork, I argue that critiques of ‘gay ordinariness’ are unable to capture extant ‘extra-ordinary’ trajectories of queer capitalist incorporation. I trace the ways in which corporate culture, leadership and values are currently reshaping queer life and politics in terms of a ‘CEO society’ to demonstrate that we should avoid assuming that anti-normativity is always on the side of the progressive and instead consider how this is taken up by the very institutions it is intended to contest.
Response control of a transmission tower-line system under wind excitations by electromagnetic inertial mass dampers
Authors: Song Xinxin , Chen Yanzhou , Bo Chen , Wu Jingbo
Published: October 2022

Structural vibration of transmission tower-line systems under wind excitations may induce damage and even destruction of the overall system. The control of transmission towers is conducted in the past decades by dynamic absorbers and dampers. Recently, a new type of passive control device, namely electromagnetic inertial mass dampers (EIMD), has been proposed and applied in structural vibration control However, the EIMD has not yet been systematically investigated in the vibration control of power transmission towers. In this regard, the vibration control of wind-disturbed transmission towers using EIMDs is conducted. The analytical model of a real tower-line system is established in line with the Hamilton principles. The response control approach using EIMDs is proposed and the control performance of different methods is compared in both the time and frequency domain. Detailed parametric studies are carried out to examine the effects of electromagnetic damping, inertial mass, and wind load intensity on EIMD performance. The assessment of the system energy responses without and with control is also conducted. The made observations demonstrate that the application of EIMDs can significantly reduce the structural dynamic responses under wind loading and the control performance of the EIMDs is quite robust and versatile under different wind load intensities.
The concept of disease in the Norwegian National Insurance Court
Authors: Von Wachenfeldt Vegard , Hofmann Bjørn Morten
Published: October 2022

Aims:

The National Insurance Act administrates an important part of the welfare system in Norway by entitlements to benefits. Disease is an absolute requirement for many benefits, but the Act does not provide any definition of disease. The National Insurance Court is the normative body in management of the Act. In 1994, a consensus report was written on the concept of disease on behalf of the National Insurance Court, which subsequently became a guideline in the management of decisions. This study examined how the concept of disease has been interpretated in recent decisions in the National Insurance Court compared to the interpretation in the consensus report.

Methods:

The material consisted of anonymous decisions from the National Insurance Court in the period from September 2018 to August 2019. It was analysed by systematic text condensation and compared to the consensus report by a theory-driven content analysis.

Results:

The consensus report described disease as a value-laden condition with personal resources and external environment as decisive context, while the decisions express disease as a process with causal relationship to personal resources and external environment.

Conclusions:

The analysis of recent decisions showed that the interpretation of the concept of disease has moved in a value-neutral direction compared to the consensus report.
Identification of colorectal cancer using structured and free text clinical data

Published: October 2022

Colorectal cancer incidence has continually fallen among those 50 years old and over. However, the incidence has increased in those under 50. Even with the recent screening guidelines recommending that screening begins at age 45, nearly half of all early-onset colorectal cancer will be missed. Methods are needed to identify high-risk individuals in this age group for targeted screening. Colorectal cancer studies, as with other clinical studies, have required labor intensive chart review for the identification of those affected and risk factors. Natural language processing and machine learning can be used to automate the process and enable the screening of large numbers of patients. This study developed and compared four machine learning and statistical models: logistic regression, support vector machine, random forest, and deep neural network, in their performance in classifying colorectal cancer patients. Excellent classification performance is achieved with AUCs over 97%.
Investigation of the effects of passive pre-chamber nozzle pattern and ignition system on engine performance and emissions
Authors: Di Sabatino Francesco , Martinez-Hernandiz Pablo Jose , Novella Rosa Ricardo , Ekoto Isaac
Published: October 2022

The impact of passive pre-chamber (PC) internal volume, nozzle hole pattern (i.e. with and without a central axial nozzle), and PC igniter plug type on performance and emissions was investigated in an optically accessible, single-cylinder, gasoline research engine. The two PC igniter plugs investigated were a conventional inductive coil spark plug and a nanosecond repetitively pulsed (NRP) plasma discharge system previously demonstrated to accelerate early flame propagation. The baseline PC design featured a funnel shaped internal volume with a PC tip that contained six radial nozzles and a larger central axial nozzle. Two additional PC tip geometries were evaluated where either the baseline internal volume was increased or the axial nozzle was removed and the radial nozzle diameters were increased. A sweep of charge equivalence ratios ( ϕ) from nearly stoichiometric to the lean limit was performed for a fixed engine speed (1300 revolutions per minute), and engine load (3.5 bar gross indicated mean effective pressure). Time-resolved PC and main chamber (MC) pressure data as well as MC emissions data were collected to analyze engine performance and emissions characteristics. Combustion in the MC was further investigated using high-speed excited methylidyne radical (CH*) chemiluminescence imaging. Collected results highlighted that while all PC tips and ignition systems exhibited similar performance and emissions down to ϕ = 0.8, relevant differences in thermal efficiency and emissions for leaner charge mixtures were observed, with the results highly dependent on the nozzle pattern and ignition system. Major deviations were correlated to preferential de-pressurization of the PC through the axial nozzle for lean conditions that was not observed for mixture conditions closer to stoichiometric. Results show that a combination of radial and axial nozzle patterns in the PC extended lean-stability limits at the low-load condition evaluated. Further benefits were observed with the use of NRP ignition systems due to faster combustion within the PC volume provided that the volume was sufficiently large.
Identifying anti-Blackness and committing to Pro-Blackness in early literacy pedagogy and research: A guide for child care settings, schools, teacher preparation programs, and researchers
Authors: Wynter-Hoyte Kamania , Braden Eliza , Boutte Gloria , Long Susi , Muller Meir
Published: October 2022

This article is written for educators who serve as teachers, administrators, policy-makers in childcare settings, schools, classrooms, teacher preparation programs, programs that prepare educational researchers, and universities. Its purpose is to provide background, rationale, and support for individuals within those institutions to address the need to identify and counter anti-Black racist structures, policies, and practice within and beyond educational spaces. While the focus is on spaces connected to early literacy education, the content of this article will also be useful for educators and educational researchers in other areas of education. After providing a framework in Critical Race and Black Critical theories and addressing attempts to interrupt and take down any teaching about racial histories or contemporary issues, the authors provide extensive lists of questions that can be used for educational stakeholders to root out anti-Blackness in their institutions. A few of the elements of institutions addressed in this article include: early literacy and teacher preparation curriculum; assessments and testing; attitudes and perceptions; and hiring and retaining Black faculty and administration. Written with love and a sense of urgency and joy in the process of change, this article will provide impetus but also explicit guidance for educators to examine and analyze elements of their own institutions and use findings to engage in change that centers the excellence, joy, resistance, and resilience of Black people.
Should I Stay or Should I Go? Behavioral Acts That Negatively Affect Relationships’ Prospects
Authors: Apostolou Menelaos
Published: October 2022

Intimate relationships are not easy to keep as the high rates of divorce and singlehood testify. The current research aimed to examine the behavioral acts which are likely to have a negative effect on people's willingness to continue an intimate relationship. More specifically, by using qualitative research methods on a sample of 269 Greek-speaking participants, Study 1 identified 88 acts that have a negative impact on people's willingness to continue an intimate relationship. Study 2 employed quantitative research methods on a sample of 536 Greek speaking participants, and classified these acts into six broader factors. The one with the most negative impact was rated to be the “Does not care about me,” followed by the “Does not treat well our children,” and the “Tries to control me.” Women and single participants rated the identified factors more negatively than men and participants who were in a relationship or married. Significant main effects of age, sex, relationship status and having children were also found for several factors.
Toward diagnostics of water-lubricated bearings of naval vessels by vibration analysis
Authors: Matania Omri , Heletz Shani , Klein Renata , Groper Morel , Bortman Jacob
Published: October 2022

Sliding bearings are mechanical components used for rotor support of high-load mechanical systems. It is assumed that a change in the lubrication regime at a known operational point is a result of an anomaly in the bearing operation such as an increased load, lack of lubricant, and damage to the bearing surface or wear. Detection of this phenomenon will enable diagnostics of the bearing. In this study, we present a novel technique for estimating the transition point between synchronous and asynchronous interactions of the shaft and bearing which is related to the transition between lubrication regimes of a water-lubricated bearing of a marine vessel by vibration analysis. The new technique is demonstrated on an experimental system that reproduces the operation of a water-lubricated bearing. The results demonstrate the ability of using vibration analysis to identify changes in the operating condition of a water-lubricated bearing.
The promises and pitfalls of government-funded teacher staffing initiatives on teacher employment in hard-to-staff schools: Evidence from South Carolina
Authors: Tran Henry , Babaei-Balderlou Saharnaz , Smith Douglas A
Published: October 2022

Situated against teacher demand problems worldwide, rising teacher turnover and declining teacher education enrollment have rendered the state of South Carolina a region commonly described as facing a “teacher shortage crisis.” This paper reports results from an evaluation of the Rural Recruitment Initiative (RRI), a state-level teacher staffing policy for SC’s hard-to-staff districts. Based on a decade of data analysis, we assess RRI’s causal effect using a Difference-in-Differences model with Arellano–Bond maximum likelihood design and find that RRI funding reduces teacher turnover rate by 1% for fund-receiving districts. We conclude by discussing how the initiative could be improved and what policymakers can learn from our results.
Effects of Prepaid Postage Stamps and Postcard Incentives in a Web Survey Experiment
Authors: Haas Georg-Christoph , Volkert Marieke , Senghaas Monika
Published: October 2022

Even small monetary incentives, e.g., a one-dollar bill in a postal invitation letter, can increase the response rate in a web survey. However, in the euro currency area, the smallest amount of monetary incentive for a postal invitation is a five-euro bill, which is costly. As such, we conducted a random experiment with prepaid stamp and postcard incentives as affordable alternatives. We compare the effect of our experimental groups with a control group in terms of response rates, response rates in a subsequent wave, data linkage consent, and data collection costs. Compared with the control group, the postcard incentive has no effect on our outcomes except overall costs. Using a prepaid stamp incentive increases the response rate overall but with different effect sizes for subgroups. We find no effect of stamp incentives on response rates in a subsequent wave or data linkage consent.
Amplatzer Vascular Plug With Endologix AFX Lining for Visceral Re-Entry Closure in a Patient With Chronic Type B Aortic Dissection
Authors: Watanabe Shuto , Saito Yoshiaki , Murata Kenyu , Kondo Norihiro , Minakawa Masahito
Published: October 2022

Purpose:

To demonstrate the efficacy of a combination of Amplatzer vascular plug (AVP2) and Endologix AFX for a visceral entry closure.

Case report:

A 70-year-old woman with treated chronic type B aortic dissection was seen to have sac enlargement. An isolated residual tear was observed at the origin of the celiac artery. A 12 mm AVP2 was successfully deployed for the entry closure. Angiography after the plug deployment still demonstrated residual flow to the false lumen. Hence, an Endologix AFX VELA proximal endograft was deployed, covering the AVP membrane and leaving no endoleak.

Conclusion:

Deployment of a vascular plug with Endologix AFX lining was efficacious for securing complete closure of an entry tear at the origin of the celiac artery in our patient.

Clinical Impact

Vascular plugs are reported to be effective for closing small entries, although their effectiveness is limited when the entry site is not located on the flat intima, or in a high-flow situation. In the presented case, an isolated entry tear at the origin of the celiac artery was successfully closed with a vascular plug following Endologix AFX stent-graft lining of the true lumen.

Mucosa-associated lymphoid tissue (MALT) lymphoma-induced hemophagocytic lymphohistiocytosis (HLH) has rarely been reported. Herein, we report the diagnosis and treatment process of a patient with MALT lymphoma-induced HLH who received chemotherapy after diagnosis and finally achieved partial remission. In this case, blood cells were only reduced to grade II at the time of diagnosis, and the patient was then treated with the R-CHOP regimen (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone). HLH responded well to treatment. Laboratory data indicative of HLH and blood chemistry results were steadily normalized, and hepatosplenomegaly resolved. One month after chemotherapy, the patient achieved partial remission. The results also showed that the treatment was successful. In conclusion, treatment of lymphoma-triggered HLH needs to balance HLH-specific and lymphoma-specific treatment. Once HLH is initially controlled or the decrease in blood cells is better than grade II, it should actively transition to lymphoma treatment.

Background:

In Ethiopia, the number of homeless girls and women is increasing, and the government has yet to devise a strategy to address the issue of teenage homelessness. They are influenced by numerous dimensions of health, including physical health, mental health, and social isolation. At all stages of homelessness, the stakeholders and homeless people must work together to address the issue. As a result, this study will be helpful to generate relevant data that may guide policymakers in designing solutions for this underserved group of people.

Objectives:

To explore coping mechanisms and suggestions to stakeholders among women experiencing homelessness in Dire Dawa city, eastern Ethiopia, 2021.

Design:

A community-based phenomenological qualitative study was conducted at Dire Dawa city.

Methods:

Data were collected from women experiencing homelessness and key informants through focus group discussion and in-depth interviews using a semi-structured tool. A total of 31 women experiencing homelessness (13 in-depth interviews and 3 focus group discussion with 6 participants in each) and 2 key informants participated in this study. Data were analyzed thematically using computer-assisted qualitative data analysis software Atlas.ti 7. The thematic analysis follows six steps: familiarization, coding, generating themes, reviewing themes, naming themes, and writing up.

Results:

Two major themes were driven: coping mechanisms and suggestions to stakeholders. There are three subthemes under the coping mechanism (begging, survival sex, and child prostitution) while there are a total of seven subthemes under suggestions to stakeholders (integration and collaboration, special attention to children, family education, shelter and job, schooling, sexual education, and addiction rehabilitation).

Conclusion:

Child prostitution and survival sex are a very common coping mechanism which is practiced by women experiencing homelessness. Changing society’s mindset and paying special attention to children is critical. Furthermore, the government and various stakeholders should work together to develop a rehabilitation program for street children who have been exposed to substance use.
Family Constellation Therapy in the Context of Esotericism
Authors: Gyimesi Júlia
Published: October 2022

In the past decades, Bert Hellinger’s family constellation method has become a highly popular psychotherapeutic modality. Although some research has emerged concerning the foundations, effectiveness, and ethical aspects of family constellation therapy, psychological inquiry has neither reflected on the popularity of the method nor addressed its specific content in detail. In this article, I trace and interpret family constellation therapy within the context of esotericism. Given that parallels between Western esoteric thought and the family constellation system developed by Hellinger can be observed, this article explores the extent to which family constellation therapy is embedded within esotericism. By exploring family constellation therapy and thus broadening the scope of esoteric spirituality, this analysis contributes to contemporary research on Western esoteric thought.
Comparison of fentanyl and nalbuphine as adjuvants to intrathecal 0.5% bupivacaine in lower limb surgeries: A randomised double-blind prospective study

Published: October 2022

Introduction:

Local anaesthetics used in spinal anaesthesia have a limited duration of action. To prolong postoperative analgesia, adjuvants, mainly opioids, are used. As µ agonist drugs have side effects, other receptor agonists are considered. Nalbuphine is a safe and effective kappa agonist adjuvant.

Aim:

To compare the analgesic efficacy between fentanyl and nalbuphine adjuvants added to 3 mL of 0.5% intrathecal hyperbaric bupivacaine.

Materials and Methods:

This prospective, double-blind, comparative study was conducted in 60 patients of either sex belonging to the American Society of Anesthesiologists classes I and II aged 18–65 years undergoing lower limb surgery with entropy monitoring, randomly allocated into two groups. Group F (n = 30) received 0.5% hyperbaric bupivacaine (3 mL) + 25 µg (0.5 mL) fentanyl. Group N (n = 30) received 0.5% hyperbaric bupivacaine (3 ml) + 0.8 mg (0.5 mL) nalbuphine intrathecally. Hemodynamics, entropy, motor and sensory block characteristics, and complications were noted.

Results:

The nalbuphine group had a significantly longer two-segment regression time of sensory blockade and extended analgesia duration than the fentanyl group. Haemodynamics, entropy, time for onset of sensory and motor blockade and adverse effects were comparable in both groups.

Conclusion:

Nalbuphine prolongs sensory blockade and postoperative analgesia duration with minimal side effects and is a safe intrathecal adjuvant.
Prostate cancer-associated urinary proteomes differ before and after prostatectomy

Background:

A wide range of disorders can be detected in the urine. Tumor-modifying proteins in the urine may serve as a diagnostic tool for cancer patients and the alterations in their profiles may indicate efficacies of chemotherapy, radiotherapy, and surgery.

Methods:

We focused on urinary proteomes of patients with prostate cancer and identified tumor-modifying proteins in the samples before and after prostatectomy. Protein array analysis was conducted to evaluate a differential profile of tumor-promoting cytokines, while mass spectrometry-based global proteomics was conducted to identify tumor-suppressing proteins.

Results:

The result revealed striking differences by prostatectomy. Notably, the urine from the post-prostatectomy significantly decreased the tumorigenic behaviors of prostate tumor cells as well as breast cancer cells. We observed that angiogenin, a stimulator of blood vessel formation, was reduced in the post-prostatectomy urine. By contrast, the levels of three cell-membrane proteins such as prostasin (PRSS8), nectin 2 (PVRL2), and nidogen 1 (NID1) were elevated and they acted as extracellular tumor-suppressing proteins. These three proteins, given extracellularly, downregulated tumorigenic genes such as Runx2, Snail, and transforming growth factor beta and induced apoptosis of tumor cells. However, the role of NID1 differed depending on the location, and intracellular NID1 was tumorigenic and reduced the percent survival.

Conclusions:

This study demonstrated that prostatectomy remarkably altered the profile of urinary proteomes, and the post-prostatectomy urine provided tumor-suppressive proteomes. The result sheds novel light on the dynamic nature of the urinary proteomes and a unique strategy for predicting tumor suppressors.
