“No creen en los psicólogos”: la construcción de la psicología desde la cotidianeidad popular de Guayaquil
Authors: Capella Manuel
Published: June 2023

En este artículo analizo la construcción de la psicología desde la cotidianidad popular de Guayaquil, Ecuador, a partir de una etnografía crítica multi-situada. Los resultados incluyen interpretaciones en torno a bienestares, malestares y alternativas terapéuticas, así como observaciones que dan cuenta de la tensión entre psicologización y resistencia cultural, la representación de psicólogas y psicólogos como portadores de un rol cargado de experticia y moralidad, y determinadas expectativas populares con respecto al trabajo psicológico. Aunque parciales, los análisis aportan a debates en curso respecto a procesos de psicologización, y la importancia de profundizar una formación intercultural en contextos urbanos heterogéneos e inequitativos con configuraciones complejas que amalgaman bienestares, sufrimientos sociales y malestares cotidianos.

Authors: Schneider Andrea L.C. , Peltz Carrie B. , Li Yixia , Bahorik Amber , Gardner Raquel C. , Yaffe Kristine
Published: June 2023

BACKGROUND:

Traumatic brain injury (TBI) is associated with significant morbidity, but the association of TBI with long-term stroke risk in diverse populations remains less clear. Our objective was to examine the long-term associations of TBI with stroke and to investigate potential differences by age, sex, race and ethnicity, and time since TBI diagnosis.

METHODS:

Retrospective cohort study of US military veterans aged 18+ years receiving healthcare in the Veterans Health Administration system between October 1, 2002 and September 30, 2019. Veterans with TBI were matched 1:1 to veterans without TBI on age, sex, race and ethnicity, and index date, yielding 306 796 veterans with TBI and 306 796 veterans without TBI included in the study. In primary analyses, Fine-Gray proportional hazards models adjusted for sociodemographics and medical/psychiatric comorbidities were used to estimate the association between TBI and stroke risk, accounting for the competing risk of mortality.

RESULTS:

Participants were a mean age of 50 years, 9% were female, and 25% were of non-White race and ethnicity. Overall, 4.7% of veterans developed a stroke over a median follow-up of 5.2 years. Veterans with TBI had 1.69 times (95% CI, 1.64–1.73) increased risk of any stroke (ischemic or hemorrhagic) compared to veterans without TBI. This increased risk was highest in the first-year post-TBI diagnosis (hazard ratio [HR], 2.16 [95% CI, 2.03–2.29]) but remained elevated for 10+ years. Similar patterns were observed for secondary outcomes, with associations of TBI with hemorrhagic stroke (HR, 3.92 [95% CI, 3.59–4.29]) being stronger than with ischemic stroke (HR, 1.56 [95% CI, 1.52–1.61]). Veterans with both mild (HR, 1.47 [95% CI, 1.43–1.52]) and moderate/severe/penetrating injury (HR, 2.02 [95% CI, 1.96–2.09]) had increased risk of stroke compared to veterans without TBI. Associations of TBI with stroke were stronger among older compared to younger individuals (
P
interaction-by-age<0.001) and were weaker among Black veterans compared to other race and ethnicities (
P
interaction-by-race<0.001).

CONCLUSIONS:

Veterans with prior TBI are at increased long-term risk for stroke, suggesting they may be an important population to target for primary stroke prevention measures.

A new microendemic species of Hunzikeria (Petunieae, Solanaceae) from the gypsum outcrops of southern Jalisco, Mexico
Authors: ORTIZ-BRUNEL JUAN PABLO , DÍAZ-MARTÍNEZ PAULINA , RUIZ-SANCHEZ EDUARDO , RODRÍGUEZ AARÓN
Published: June 2023

Hunzikeria is a petunioid genus of Solanaceae that includes three species. The genus presents a disjunct distribution between South and North America. Hunzikeria coulteri and H. texana occur in North America, while H. steyermarkiana is reported from Venezuela. During botanical explorations in western Mexico, we found a population of Hunzikeria that differed from the three known species. Believing that we had found an undescribed species, we collected samples and prepared herbarium vouchers. We compared our material with morphological descriptions and herbarium specimens of the other species in the genus. Our results indicate that we discovered a new species, named here as Hunzikeria gypsophila. This new species is a microendemic gypsophyte that inhabits two gypsum ravines in southern Jalisco, Mexico. Hunzikeria gypsophila differs from the other three species in being a subshrub of taller stature and having petiolate leaves, wider leaf blades, longer corolla tubes, and broader corolla limbs. The most morphologically similar species is H. steyermarkiana, which differs in having anthers of equal size, while all the North American species have didynamous anthers. Hunzikeria shows a clear affinity for sedimentary soils and H. gypsophila is the first species recorded on gypsum. The gypsum outcrops of western Mexico have a unique flora, which likely became isolated due to volcanic activity. With this new find, Hunzikeria comprises four species. We provide a key for their identification and a distribution map for Mexico.

The genus Liothrips (Thysanoptera, Phlaeothripidae) in Australia
Authors: MOUND LAURENCE A. , DANG LIHONG , TREE DESLEY J.
Published: June 2023

Eight species of Liothrips are recognised from Australia, including L. burwelli sp.n., L. chionanthes sp.n. and L. timonii sp.n., also three species shared with southeast Asia. Evidence is presented that L. vaneeckei, the Lily Bulb Thrips, is widespread in eastern Australia presumably on native plants, and that it has been on this continent for many years. The illustrated identification key includes a ninth species, L. urichi, as a potential introduction to Australia for biocontrol purposes. L. brevifemur Girault is considered a nomen dubium known only from fragments of the unique holotype. Two species are newly transferred from Liothrips as Teuchothrips soror (Hood) comb. nov. and Kellyia tenuis (Hood) comb. nov. Generic relationships are discussed, particularly with one new species that is intermediate in structure between Liothrips and Gynaikothrips.
DNA barcoding facilitates discovery and description of two new species of the Mystacides azureus Species Group (Trichoptera: Leptoceridae) in Japan
Authors: KUHARA NAOTOSHI , NOZAKI TAKAO , ZHANG AO , ZHOU XIN
Published: June 2023

We examined adult specimens of the Mystacides azureus Species Group (Trichoptera: Leptoceridae) collected in Japan and confirm three species including M. azureus Linnaeus 1761 and two new species, M. rivularis and M. moritai. Males and females of the new species are described. Mystacides azureus in Japan is shown to have a considerable variation in morphology of the male tergum X. We analyzed mitochondrial COI barcodes of the genus Mystacides including these three species to confirm their species status. A maximum likelihood phylogeny based on COI barcodes shows monophyly of the new species. It also supports the hypothesis that morphological variation of the male tergum X in Japanese populations is intraspecific in only M. azureus.

Single-forcing large ensembles are a relatively new tool for quantifying the contributions of different anthropogenic and natural forcings to the historical and future projected evolution of the climate system. This study introduces a new single-forcing large ensemble with the Community Earth System Model, version 2 (CESM2), which can be used to separate the influences of greenhouse gases, anthropogenic aerosols, biomass burning aerosols, and all remaining forcings on the evolution of the Earth system from 1850 to 2050. Here, the forced responses of global near-surface temperature and associated drivers are examined in CESM2 and compared with those in a single-forcing large ensemble with CESM2’s predecessor, CESM1. The experimental design, the imposed forcing, and the model physics all differ between the CESM1 and CESM2 ensembles. In CESM1, an “all-but-one” approach was used whereby everything except the forcing of interest is time evolving, while in CESM2 an “only” approach is used, whereby only the forcing of interest is time evolving. This experimental design choice is shown to matter considerably for anthropogenic aerosol-forced change in CESM2, due to state dependence of cryospheric albedo feedbacks and nonlinearity in the Atlantic meridional overturning circulation (AMOC) response to forcing. This impact of experimental design is, however, strongly dependent on the model physics and/or the imposed forcing, as the same sensitivity to experimental design is not found in CESM1, which appears to be an inherently less nonlinear model in both its AMOC behavior and cryospheric feedbacks.
Seasonal and Geographical Variations in Fundamental Weather Patterns during Extreme Precipitation as Identified from Omega Equation Forcing
Authors: Swenson Leif M. , Grotjahn Richard
Published: June 2023

We investigate the large-scale weather patterns during extreme precipitation (PEx) events over the conterminous United States (CONUS) by applying a version of the quasigeostrophic (QG) omega equation. This work aims to develop a climatology of the weather patterns most related to PEx events during current climate. Extreme events are examined for each of seven regions defined by consistent annual cycles of precipitation and spanning the CONUS. For the CONUS we train several self-organizing maps (SOM) on a pressure–time series of vertical velocity from each of the advective forcing terms in the QG omega equation for each extreme event. The unsupervised learning of the SOM allows us to identify the most descriptive set of nine patterns in vertical velocity associated with precipitation extremes. This method finds multiple frontal- and cyclone-driven patterns while grouping primarily convective events into one pattern. Frontal events include a synoptic pattern consistent with West Coast atmospheric river events as well as pattern groups linked to developing and to mature (“occluded”) frontal cyclones. The primary patterns found during PEx events vary seasonally and geographically. Frontal cyclone patterns are most common during PEx events during summer in the part of the Great Plains and during winter for the Northeast, Southeast, Pacific Northwest, and Southwest. Convection is the most common pattern during summer in all regions. Except in the Southeast, the annual cycles of monthly number of PEx events and average precipitation match well, partially validating our choice of regions to aggregate PEx events.
Human Rights of the HIV-Infected Persons in India: Issues and Concerns
Authors: Rajagopal PK
Published: June 2023

Human rights are basic rights of human beings regardless of gender, religious identity and nationality. Human beings and their rights are constitutionally and legally protected. Though safeguards are there against human rights violations, Human Immunodeficiency Virus (HIV) infected people have to face several injustices in our society. People living with HIV are usually subjected to discrimination in the society even in the 21st century. Society’s attitude towards these people is that of stigma and discrimination. They are provided with the right to privacy according to the current human rights standards. However, the fact is that for the prevention of further spread of HIV, disclosure of HIV-positive status is imperative. Unless the society’s attitude towards HIV-infected persons changes, an HIV/AIDS-free world cannot be dreamt of.
Experimental investigation on mechanical properties, shrinkage and warpage of injection molded short glass fiber reinforced polypropylene
Authors: Sadr Kenari Mohammad Reza , Zolfaghari Abbas
Published: June 2023

Polymer composites have remarkable popularity in the aerospace and automotive industries due to their high strength-to-weight ratio and ease of production. In this study, the effects of the glass fiber (GF) and maleic anhydride grafted polypropylene (PP-g-MA) as coupling agent on mechanical properties, shrinkage and warpage of polypropylene (PP) were investigated. Tensile, flexural, shrinkage and warpage tests were performed according to relevant standards. Results indicate that the strengths and moduli of composite specimens have been significantly improved compared to pure PP. Also, the shrinkage and warpage of composite specimens were reduced. Analysis of variance showed that both GF and PP-g-MA had a significant effect. In composite with a 40% weight fraction of GF, the tensile and flexural strengths were increased by 91% and 62%, respectively. A micromechanics model was proposed to predict the tensile modulus of composites. A good agreement between experiments and the model was achieved.
Black Mothers’ Concern for Their Children as a Measure of Vicarious Racism-Related Vigilance and Allostatic Load
Authors: Daniels Kathryn P. , D. Thomas Marilyn , Chae David H. , Allen Amani M.
Published: June 2023

This study investigates the relationship between allostatic load and a novel form of altruistic racism-related fear, or concern for how racism might harm another, which we term vicarious racism-related vigilance. Using a subsample of Black mothers from the African American Women’s Heart & Health Study (N = 140), which includes detailed health and survey data on a community sample of Black women in the San Francisco Bay Area, this study investigates the relationship between Black mothers’ experiences with racism-related vigilance as it relates to their children and allostatic load—a multisystem metric of underlying health across multiple biological systems. Findings indicate that vicarious racism-related vigilance was positively associated with allostatic load (i.e., worse health). Findings highlight the salience of vicarious racism-related vigilance for the health of Black mothers, underscoring how intersections between race, gender, and parenthood result in susceptibility to unique forms of health-harming stress.
Harmonisation of education, training and continuing professional development for laboratory animal caretakers, technicians and technologists: Report of the FELASA-EFAT Working Group
Authors: Abelson Klas SP , Chambers Charlie , De La Cueva Teresa , Fisher Glyn , Hawkins Penny , Ntafis Vasileios , Pohlig Paul F , Rooymans T Pim , Santos Ana I
Published: June 2023

Competent, confident and caring laboratory animal caretakers, technicians and technologists (LAS staff) are vital for good animal welfare, high-quality science and a secure Culture of Care. This requires high-quality education, training, supervision and continuing professional development (CPD) of LAS staff. However, there is a lack of harmonisation regarding how this education and training is conducted among European countries, and nor are there recommendations adapted to Directive 2010/63/EU. Therefore, FELASA and EFAT established a working group with the task of establishing recommendations for education, training and CPD for LAS staff. The working group established five different levels (LAS staff levels 0–4), defining the required level of competence and attitude, as well as suggesting educational requirements for reaching each level. Defining these levels should help to ensure that appropriate educational and CPD activities are in place, and to enable employers and LAS staff to determine the level and career stage attained. Furthermore, proper assessment of competencies and effective CPD schemes for all relevant staff should be established. Regulators should support this by setting standards for competence assessment and ensuring that they are consistently applied. In addition, establishments should involve the LAS staff in defining and developing the Culture of Care. The Animal Welfare Body should be involved and have oversight of education, training and CPD. These recommendations will contribute to harmonisation and increased quality of education, training and CPD, as well as provide clearer career pathways for LAS staff, helping to ensure high standards of animal welfare and science.
The superhero effect: How enclothed cognition can impact on the perceptions and actions of serving UK police officers
Authors: Andrews Tom
Published: June 2023

The theory of ‘enclothed cognition’ posits that clothes alone can significantly alter their wearer's outlook on life. Based on this idea, this article examines the world view of uniformed British police officers seeking to understand whether their uniform impacts on their attitudes and behaviours. Using data from a survey of 91 uniformed officers, results suggest that their uniform does indeed affect how they behave and their perceptions of self. Recommendations are made for changes to uniforms with the intent to reduce assaults by and against officers and complaints, as well as increase morale and productivity.
The Relationships of Hope, Optimism, and Academic Motivation With GPA Among University Students in Hong Kong
Authors: Ge Jacqueline L. , Feldman David B. , Shu Tse-Mei
Published: June 2023

Research demonstrates the relationship between dispositional hope and GPA, but mixed results regarding the relationship between dispositional optimism and GPA. Hope and optimism also have been shown to predict academic motivation. However, no study has yet investigated all of these factors together, and most research concerns only Western samples. In a cross-sectional sample of 129 Hong Kong university students, we administered measures of internal hope (hope regarding one’s own capabilities), external-family hope (hope derived from family), optimism, and intrinsic and extrinsic academic motivation. We found significant zero-order correlations between internal hope and GPA, but not between external-family hope nor optimism and GPA. Mediation analyses showed that internal hope directly related to GPA, and did not appear mediated by academic motivation. Given our findings, future studies testing hope-based interventions in similar samples may be warranted. We discuss implications for culturally adapting hope interventions.
Examining the association between self-control and mental health among adolescents: The mediating role of resilience
Authors: Şimşir Gökalp Zeynep
Published: June 2023

Failure of self-control is one of the core characteristics of numerous mental health issues. The significance of self-control for mental health is well known, but studies investigating the association between self-control and mental health and the mechanisms underlying this association are quite limited, especially in adolescents. The current cross-sectional study aimed to test the mediating role of resilience in the relationship between self-control and mental health (i.e. psychological well-being and mental health problems) in adolescents. The sample comprised 405 high school students from a state school in one of the major cities of Turkey. Participants’ ages ranged from 13 to 18 years ( Mage = 15.94, SD = 1.11), and 34.6% identified as male and 65.4% as female. Findings showed that self-control was positively correlated with psychological well-being and resilience but negatively correlated with mental disorders. Additionally, resilience mediated the association between self-control and mental health disorders as well as the association between self-control and psychological well-being. The study's results are discussed in the context of previous research, and implications for psychologists and mental health professionals working in schools are offered.
Take Healing into Our Own Hands: A Content Analysis of Alternative Medicine and Wellness Programs on Netflix
Authors: Cali Alec
Published: June 2023

A content analysis of two complementary and alternative medicine (CAM) streaming shows on Netflix is presented. This qualitative analysis of the two interview-style shows reveals the influence of political beliefs in support of CAM and wellness lifestyles. Subjects in both television shows used the language of neoliberalism to describe their desires for and qualms with existing healthcare. The advantage of CAM and wellness lifestyles originated from its comparative emphasis on personal choice and market solutions to standard medicine. Finally, it is discussed how these political undercurrents can be leveraged to improve the outcome of education campaigns.
Remittance Modality: Unpacking Canadian Money Transfer Mechanism Choices
Authors: MacIsaac Samuel
Published: June 2023

Numerous international development targets aim to encourage and formalize remittances, because they can support development efforts while controlling and monitoring illicit capital flows. Despite continued efforts to promote formal remittance channels, informal remittances flourish among specific population groups. This study uses data from the Canadian Study on International Money Transfers to analyze the determinants of remittance modality or channel choice. Previous empirical work tends to classify remittances as either formal or informal. In contrast, this article considers a variety of channels. It shows that the dichotomization of formal versus informal remittances masks crucial differences across remittance channels. Due to Canada's unique geographical positionality, cash transfers operate distinctly from informal methods despite often being treated as a homogenous group in other studies. Interestingly, remitters are also more likely to use formal money transfer operators (most of which offer cash pickup options to recipients) than informal channels to send funds to countries with larger informal sectors. Within the context of Canadian remittance outflows, this invalidates the frequent assumption that more informal destination country economies push remitters to opt for informal transfer methods.
Refugee Entrepreneurship: A Systematic Review of Prior Research and Agenda for Future Research
Authors: Newman Alexander , Macaulay Luke , Dunwoodie Karen
Published: June 2023

Over the last two decades, ever-increasing numbers of refugees have left their home countries. As of 2022, around 27 million people were registered as refugees with the United Nations High Commissioner for Refugees (UNHCR). While some consider refugees to be a burden on their host countries, there is growing evidence that they make significant contributions to host countries’ economies, with rates of entrepreneurship higher than other migrant groups and host country nationals. To take stock of what is known about refugee entrepreneurship, this article undertakes a systematic review of the refugee entrepreneurship empirical literature. The systematic review provides insights into the factors which shape refugees’ initiation of, engagement in, and performance of entrepreneurial endeavors and identifies gaps and inconsistencies in the current refugee entrepreneurship literature. Based on these gaps and inconsistencies, a future research agenda is proposed. By taking stock of what is known and proposing a future research agenda, this review has scholarly implications for the academic advancement of refugee entrepreneurship. Additionally, this review has policy implications. By better understanding the field of refugee entrepreneurship and its social and economic benefits, government policy-makers will be better positioned to design responsive policies to support refugee entrepreneurs in establishing their entrepreneurial endeavors. Finally, the findings of this review have practical implications for refugee entrepreneurs themselves, for example, by highlighting the resources that will assist entrepreneurs in pursuing entrepreneurship.
Meta-Analysis: Quality of Life and Marketing Systems

Published: June 2023

The authors introduce meta-analysis as a compelling tool for macromarketing research in an increasingly complex and data-driven world, and share an example of its application. They synthesize and generalize empirical findings on the relationships between marketing systems (MS) and quality-of-life (QOL), two concepts integral to macromarketing. Results indicate dimensions of MS are positively associated with QOL, suggesting that marketing systems enhance consumer well-being across contexts and metrics. The promotion dimension of MS has the highest correlation with QOL; the strongest positive MS-QOL relationship was estimated for personal health. Measurement, cultural, and socioeconomic factors that affect the strength of MS-QOL relationships also were assessed. Results suggest the association between MS and QOL is stronger in studies based on primary/subjective measures of QOL constructs, in samples drawn from developed economies, and in more indulgent, uncertainty-tolerant, and long-term-oriented cultures. Implications for theory, policy, practice, and opportunities for further research are discussed.
Enabling four-arm laparoscopic surgery by controlling two robotic assistants via haptic foot interfaces
Authors: Hernandez Sanchez Jacob , Amanhoud Walid , Billard Aude , Bouri Mohamed
Published: June 2023

Robotic surgery is a promising direction to improve surgeons and assistants’ daily life with respect to conventional surgery. In this work, we propose solo laparoscopic surgery in which two robotic arms, controlled via haptic foot interfaces, assist the task of the hands. Such a system opens the door for simultaneous control of four laparoscopic tools by the same user. Each hand controls a manipulative tool while a foot controls an endoscope/camera and another controls an actuated gripper. In this scenario, the surgeon and robots need to work collaboratively within a concurrent workspace, while meeting the precision demands of surgery. To this end, we propose a control framework for the robotic arms that deals with all the task- and safety-related constraints. Furthermore, to ease the control through the feet, two assistance modalities are proposed: adaptive visual tracking of the laparoscopic instruments with the camera and grasping assistance for the gripper. A user study is conducted on twelve subjects to highlight the ease of use of the system and to evaluate the relevance of the proposed shared control strategies. The results confirm the feasibility of four-arm surgical-like tasks without extensive training in tasks that involve visual-tracking and manipulation goals for the feet, as well as coordination with both hands. Moreover, our study characterizes and motivates the use of robotic assistance for reducing task load, improving performance, increasing fluency, and eliciting higher coordination during four-arm laparoscopic tasks.
Combined texture analysis of dynamic contrast-enhanced MRI with histogram analysis of diffusion kurtosis imaging for predicting IDH mutational status in gliomas
Authors: Pan Ting , Su Chun-Qiu , Tang Wen-Tian , Lin Jie , Lu Shan-Shan , Hong Xun-Ning
Published: June 2023

Background

Non-invasive detection of isocitrate dehydrogenase (IDH) mutational status in gliomas is clinically meaningful for molecular stratification of glioma; however, it remains challenging.

Purpose

To investigate the usefulness of texture analysis (TA) of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and histogram analysis of diffusion kurtosis imaging (DKI) maps for evaluating IDH mutational status in gliomas.

Material and Methods

This retrospective study enrolled 84 patients with histologically confirmed gliomas, comprising IDH-mutant (n = 34) and IDH-wildtype (n = 50). TA was performed for the quantitative parameters derived by DCE-MRI. Histogram analysis was performed for the quantitative parameters derived by DKI. Unpaired Student's t-test was used to identify IDH-mutant and IDH-wildtype gliomas. Logistic regression and receiver operating characteristic (ROC) curve analyses were used to compare the diagnostic performance of each parameter and their combination for predicting the IDH mutational status in gliomas.

Results

Significant statistical differences in the TA of DCE-MRI and histogram analysis of DKI were observed between IDH-mutant and IDH-wildtype gliomas (all P < 0.05). Using multivariable logistic regression, the entropy of Ktrans, skewness of Ve, and Kapp−90th had higher prediction potential for IDH mutations with areas under the ROC curve (AUC) of 0.915, 0.735, and 0.830, respectively. A combination of these analyses for the identification of IDH mutation improved the AUC to 0.978, with a sensitivity and specificity of 94.1% and 96.0%, respectively, which was higher than the single analysis ( P < 0.05).

Conclusion

Integrating the TA of DCE-MRI and histogram analysis of DKI may help to predict the IDH mutational status.
Modeling and stability analysis of a sliding bead from a problem-based learning perspective
Authors: Roccia Bruno A , Bossio Guillermo R , Mazzone Fernando D , Gebhardt Cristian G
Published: June 2023

In this work, we adopt a problem-based learning approach to develop an integrative bachelor project that relies on competences acquired from basic courses in mathematics, mechanics and computation. In this sense, the proposed project tries to pave the way from “apparently disconnected” concepts gained through previous studies toward the field of computational mechanics. On this basis, we study the motion of a particle along an arbitrary curve in space subject only to the gravitational field, the so-called sliding bead. Although this is a classic problem in mechanics, it has a substantial richness from a theoretical and practical point of view where the student reinforcing abstract skills and exploring different aspects of its numerical solution are allowed. Along this path, we start with the modeling process. This is followed by a stability analysis of the governing differential equations. Later on, we present a moderate introduction to classical numerical time integration by considering several numerical schemes and the well-known Matlab add-on Simulink. Finally, we present a brief discussion about how the proposed project allows articulating concepts of mathematics, mechanics, and computation in engineering programs of studies at horizontal and vertical levels.
Offerings Matter: Revisiting the Sabbath Transgression in Nehemiah 13 and the So-Called Sabbath Reform
Authors: Noya Ludwig Beethoven J.
Published: June 2023

Recent interpretations of the Sabbath rest concept in the Hebrew Bible tend to highlight its humanitarian aspect. However, in this paper, I aim to nuance this claim by attending to a rarely discussed Sabbath text in Nehemiah 13. I will argue that the Sabbath rest motif in Nehemiah is less concerned about the humanitarian aspect than the temple’s maintenance while at the same time fulfilling the imperial tax obligation. The Sabbath rest motif supports Nehemiah’s demand for the temple’s communal funding through tithes and offerings. To support this argument, I begin by reviewing the discussion about the Achaemenid imperial rule over the Jerusalem temple and its tax obligation. Scholars differ on how significant the Jerusalem temple was for the imperial administration, but some sort of obligation to the empire is generally accepted. After that, I analyze how the Sabbath concept is manifested in Neh. 13.15–22 in relation to its literary contexts. Along with clearing the temple storeroom, maintaining temple resources, and restricting exogamy, the Sabbath concept facilitates the temple’s maintenance and the meeting of the imperial tax obligation.
Investigations of the subarachnoid space as a potential link between aura and headache in migraine: A case-control MRI study
Authors: Thomsen Andreas Vinther , Puonti Oula , Gaist David , Kyvik Kirsten Ohm , Madsen Kristoffer , Thielscher Axel , Siebner Hartwig Roman , Ashina Messoud , Hougaard Anders
Published: June 2023

Background

The connection between migraine aura and headache is poorly understood. Some patients experience migraine aura without headache, and patients with migraine aura with headache commonly experience milder headaches with age. The distance between the cerebral cortex and the overlying dura mater has been hypothesized to influence development of headache following aura. We tested this hypothesis by comparing approximated distances between visual cortical areas and overlying dura mater between female patients with migraine aura without headache and female patients with migraine aura with headache.

Methods

Twelve cases with migraine aura without headache and 45 age-matched controls with migraine aura with headache underwent 3.0 T MRI. We calculated average distances between the occipital lobes, between the calcarine sulci, and between the skull and visual areas V1, V2 and V3a. We also measured volumes of corticospinal fluid between the occipital lobes, between the calcarine sulci, and overlying visual areas V2 and V3a. We investigated the relationship between headache status, distances and corticospinal fluid volumes using conditional logistic regression.

Results

Distances between the occipital lobes, calcarine sulci and between the skull and V1, V2 and V3a did not differ between patients with migraine aura with headache and patients with migraine aura without headache. We found no differences in corticospinal fluid volumes between groups.

Conclusion

We found no indication for a connection between visual migraine aura and headache based on cortico-cortical, cortex-to-skull distances, or corticospinal fluid volumes overlying visual cortical areas. Longitudinal studies with imaging sequences optimized for measuring the cortico-dural distance and a larger sample of patients are needed to further investigate the hypothesis.
Transforming Hospitality in the Theology of Paul: Lessons for Today's Church
Authors: Mackenzie Ed
Published: June 2023

Hospitality is central to ministry, but the stress churches give to welcome can sometimes dilute the call to discipleship. In this article, I explore Paul's approach to hospitality, which includes transformation alongside welcome. Following a general discussion of Christian hospitality, I trace Paul's approach to hospitality in three areas: the hospitality of God, hospitality within the church, and hospitality toward outsiders. In my final section, I unpack some contemporary implications of Paul's approach.
Fictional books in Coptic apocrypha
Authors: Lundhaug Hugo
Published: June 2023

Coptic literature abounds with references to books that never existed as physical objects in their own right. This article explores the role of fictional books specifically in a selection of Coptic apocrypha deriving from the entire period of Coptic literary production. Whether presented as apostolic, prophetic, or angelic; earthly or heavenly; historical or contemporary, references to fictional books could function as veracity devices, authority claims, or as materials for storyworld creation. Taking as its points of departure recent work on pseudo-documentarism, transnarrative storyworlds, and the cognitive effects of fiction, this article explores implicit claims to authority and authenticity, as well as the fuzzy boundaries and interrelationships between fictional and factual references in meaning- and world-making.

As the most important component of the braking pressure regulation circuit, apply valve directly affect the accuracy of pressure control and estimation, which in turn affects the performance of vehicle dynamics control. However, the not exactly same parameters in the manufacturing and the parameters change with wear and tear will introduce large errors in the model-based pressure estimation. In this paper, the electromagnetic model and hydraulic model of apply valve are proposed and illustrated, which is the basis for pressure estimation and air gap learning. The particle swarm optimization (PSO) is presented for the self-learning of apply valve air gap, and the pressure estimation algorithm is presented based on the learned air gap. The proposed model and the algorithm are verified in the vehicle test and Amesim simulation. The results show that the proposed algorithm achieves the estimation of air gap within the error of [Formula: see text], and thus reduces pressure estimation error to smaller than [Formula: see text].

The FAST (Five-hundred-meter Aperture Spherical Telescope) is the world’s largest single-aperture radio telescope. During operation, FAST needs to follow the observed celestial body to adjust displacements, which can be divided into two processes: the source finding and tracking. In this paper, a new numerical method based on Vector Form Intrinsic Finite Element (VFIFE) is proposed to simulate the source finding and tracking process for FAST’s active reflector. The basic principle of static equilibrium and calculation flow of the sourcing and tracking analysis is proposed, and the finite element program is compiled to analyze the displacement process of the reflector cable-net structure. Then, six typical test conditions are selected to simulate the sourcing and tracking displacement process. The obtained final form in the equilibrium state adheres to the target configuration, demonstrating the applicability of the suggested approach and the correctness of calculation findings. In addition, the change in the actuator length and the structural force distribution can be simultaneously derived. These values serve as a vital theoretical foundation for FAST’s practical operation and regulation.

Rates of diabetes in youth are rising and more than 1 million children have diabetes. School nurses are central to a school-aged child's diabetes care and they must make important moment-to-moment decisions requiring understanding of and comfort with diabetes care and technology. The rapid changes in diabetes care and technology make ongoing education essential, yet access to up-to-date and practical education is limited for many school nurses. Integrating needs data and stakeholders’ input, this group developed Diabetes in School Health (DiSH) to address this gap. We adapted a well-established, innovative, and easily-accessible telementoring educational model, Project ECHO, to create a collaborative learning community. In the first year, 9 diabetes experts and >150 school nurses joined live DiSH sessions. DiSH has been well-received by the school community and next steps include expansion of DiSH to other states and study of impact of DiSH on health disparities.

Background. Ganglioneuroblastoma is a borderline tumor of sympathetic origin that is considered a childhood disease, with the majority of patients occurring in children less than five years old and few patients occurring in adults. There are no treatment guidelines for adult ganglioneuroblastoma. Here, we report a rare patient of adult gastric ganglioneuroblastoma that was completely resected by a laparoscopic approach. Case presentation. A 73-year-old man presented with dull pain in the upper abdomen along with abdominal distension for one month. Gastroscopy examination revealed chronic gastritis and submucosal tumors of the gastric antrum. Endoscopic ultrasonography showed a hypoechoic mass in the gastric antrum arising from the muscularis propria. An abdominal computed tomography scan revealed an irregular soft tissue mass in the gastric antrum with heterogeneous enhancement in the arterial phase. The mass was completely resected by laparoscopic surgery. Postoperative histopathology revealed that the mass contained differentiated neuroblasts, mature ganglion cells and ganglioneuroma components. The pathological diagnosis was ganglioneuroblastoma intermixed, and the patient was determined to be in stage I. The patient received no adjuvant chemotherapy or radiotherapy. At his two-year follow-up, the patient was doing well and showed no signs of recurrence. Conclusion. Despite the rarity of gastric ganglioneuroblastoma as a primary site of origin, it should be considered in the differential diagnosis of gastric masses in adults. Radical surgery is sufficient for the treatment of ganglioneuroblastoma intermixed, and long-term follow-up should be performed.
The Value of Better Vehicle Occupancy Estimates for Project Prioritization
Authors: Xu Yiqing , Dougald Lance E. , Miller John S.
Published: June 2023

Transportation projects are increasingly evaluated based on how they improve person throughput, which requires knowing the passenger car occupancy. Yet obtaining occupancies is labor intensive, leading agencies to rely on statewide values. How useful are locality-specific vehicle occupancies? A case study of 38 candidate Virginia highway investments showed an occupancy change of .15 randomly applied to one-half of the projects affects 24% to 42% of project rankings if locality-specific occupancies are used. Occupancy is not the only data element affecting project prioritization, but it is an underlooked one. The study showed that an occupancy uncertainty of .15 is equivalent to an uncertainty of 3.90% in the discount rate or 13.2% in assigned traffic volume. As these investments had a mean value of $17 M, this study demonstrated that when project prioritization metrics are based on person throughput, city-or county-specific occupancies are an integral component of a data-driven prioritization process.

Objective:

Clinical guidelines provide recommendations on the minimal blood vessel diameters required for arteriovenous fistula creation but the evidence for these recommendations is limited. We compared vascular access outcomes of fistulas created in agreement with the ESVS Clinical Practice Guidelines (i.e. arteries and veins >2 mm for forearm fistulas and >3 mm for upper arm fistulas) with fistulas created outside these recommendations.

Methods:

The multicenter Shunt Simulation Study cohort contains 211 hemodialysis patients who received a first radiocephalic, brachiocephalic, or brachiobasilic fistula before publication of the ESVS Clinical Practice Guidelines. All patients had preoperative duplex ultrasound measurements according to a standardized protocol. Outcomes included duplex ultrasound findings at 6 weeks after surgery, vascular access function, and intervention rates until 1 year after surgery.

Results:

In 55% of patients, fistulas were created in agreement with the ESVS Clinical Practice Guidelines recommendations on minimal blood vessel diameters. Concordance with the guideline recommendations was more frequent for forearm fistulas than for upper arm fistulas (65% vs 46%, p = 0.01). In the entire cohort, agreement with the guideline recommendations was not associated with an increased proportion of functional vascular accesses (70% vs 66% for fistulas created within and outside guideline recommendations, respectively; p = 0.61) or with decreased access-related intervention rates (1.45 vs 1.68 per patient-year, p = 0.20). In forearm fistulas, however, only 52% of arteriovenous fistulas created outside these recommendations developed into a timely functional vascular access.

Conclusions:

Whereas upper arm arteriovenous fistulas with preoperative blood vessel diameters <3 mm had similar vascular access function as fistulas created with larger blood vessels, forearm arteriovenous fistulas with preoperative blood vessel diameters <2 mm had poor clinical outcomes. These results support that clinical decision-making should be guided by an individual approach.
When do rebels sign agreements with the United Nations? An investigation into the politics of international humanitarian engagement
Authors: Jo Hyeran , Yi Joowon

International actors engage rebel groups in conflict zones for better humanitarian outcomes. What are the political conditions under which such external engagement occurs in internal conflict zones? We argue that “insecure governments” and politically “modulated rebels” are the key factors that explain the international humanitarian engagement with rebels in civil conflicts. With the history of instability marred by coups and frequently changing hands of governments, insecure governments resort to international help and allow international actors to interact with their internal enemies. In contrast, with strong political control and military capacity, secure governments play a gatekeeper role, dealing with internal enemies autonomously. On the rebel side, politically “modulated rebels” are the prime candidates for international humanitarian engagement. Such modulation is likely to occur after civilian-connecting experiences over time by holding territory or after peace talks. We test these arguments using the case of the United Nations (UN) action plans between 2000 and 2015, in which some rebel groups committed to reducing the practice of child soldiering. We find that the combination of “insecure governments” and “modulated rebels” can systematically account for the UN action plans occurrence. Our analysis has implications for the role of external actors in internal conflict zones around the world.
