Authors: Guejdad Khadija , Ikrou Ali , Strandell-Laine Camilla , Abouqal Redouane , Belayachi Jihane
Published: May 2024

Background. The clinical learning environment (CLE) is critical for developing the practical skills needed in healthcare professions. This study aimed to evaluate healthcare students’ perceptions of the quality of the CLE using the Arabic version of the Clinical Learning Environment, Supervision and Nurse Teacher (ar. CLES + T) scale. The study also aimed to evaluate the tool’s measurement invariance and compare perceptions among student groups. Methods. This cross‐sectional study was carried out at two health education institutes in Morocco throughout the academic year 2018‐2019 among 1550 undergraduate students who had just finished a clinical practicum in a hospital or primary healthcare facility. Data were gathered using the ar. CLES + T scale. Confirmatory factor analysis (CFA) and multigroup CFA were performed. The measurement invariance of the ar. CLES + T scale was assessed across gender, study year, and clinical practicum duration, using configural invariance, metric invariance, scalar invariance, and strict invariance. The t‐test and analysis of variance were used to compare the mean scores of the student groups. Results. Students expressed positive perceptions toward the CLE. The “Pedagogical atmosphere on the ward” dimension scored the highest, while the “Role of the nurse teacher” dimension received the lowest scores. The measurement invariance of the ar. CLES + T scale by gender, study year, and clinical practicum duration was established. First‐year students and those with an extended practicum period were the most satisfied. Conclusion. To promote effective learning in the clinical environment, nurse teachers might use innovative teaching approaches tailored to their evolving role in these settings. Moreover, extending the duration of clinical practicum can further enhance student learning outcomes.

Published: May 2024

Neuroblastoma is an embryonic cancer that contributes disproportionately to death in young children. Sequencing data have uncovered few recurrently mutated genes in this cancer, although epigenetic pathways have been implicated in disease pathogenesis. We used an expression-based computational screen that examined the impact of deubiquitinating enzymes on patient survival to identify potential new targets. We identified the histone H2B deubiquitinating enzyme USP44 as the enzyme with the greatest impact on survival in patients with neuroblastoma. High levels of USP44 significantly correlate with metastatic disease, unfavorable histology, advanced patient age, and MYCN amplification. The subset of patients with tumors expressing high levels of USP44 had significantly worse survival, including those with tumors lacking MYCN amplification. We showed experimentally that USP44 regulates neuroblastoma cell proliferation, migration, invasion, and neuronal development. Depletion of the histone H2B ubiquitin ligase subunit RNF20 resulted in similar findings, strongly implicating this histone mark as the target of USP44 activity in this disease. Integration of transcriptome and epigenome in analyses demonstrates a distinct set of genes that are regulated by USP44, including those in Hallmark MYC target genes in both murine embryonic fibroblasts and the SH-SY5Y neuroblastoma cell line. We conclude that USP44 is a novel epigenetic regulator that promotes aggressive features and may be a novel target in neuroblastoma.

Implications: This study identifies a new genetic marker of aggressive neuroblastoma and identifies the mechanisms by which its overactivity contributes to the pathophysiology of this disease.

Published: May 2024

Objective: Chronic inflammation is considered to be of key importance in the pathogenesis of polycystic ovarian syndrome (PCOS). Ganoderma lucidum polysaccharide (GLP) and Hypericum perforatum (HP) have been reported to have anti-inflammatory and antioxidant activities. We studied the effects of these agents on ovarian tissue in a rat model of experimental PCOS. Materials and Methods: Forty-two Sprague-Dawley female rats were divided into 6 groups with 7 animals in each group as listed below: Group 1: Control, Group 2: PCOS, Group 3: PCOS + HP, Group 4: HP only, Group 5: PCOS+ GLP, Group 6: GLP only. At the end of the experimental procedures, all the animals underwent bilateral oophorectomy and blood samples were collected. Ovarian tissue and blood samples were used for biochemical and histopathological analysis. Results: Follicle degeneration in the PCOS group showed a statistically significant increase compared to the other groups (p < 0.05). Cystic follicles were significantly reduced in the PCOS+GLP and PCOS+HP groups as compared to the PCOS group. Levels of tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) were elevated in PCOS rats (p < 0.01). Levels of sex hormone binding globulin (SHBG) levels were diminished (p < 0.01). Levels of malondialdehyde (MDA) and insulin-like growth factor 1 (IGF-1) were increased in PCOS rats as compared to the other groups (p < 0.02, p < 0.02, respectively). GLP supplementation diminished the levels of IGF-1 and MDA. GLP or HP supplementation increased reduced glutathione (GSH). Conclusion: GLP and HP treatment normalizes SHBG levels while correcting PCOS-induced hyperandrogenemia. Both herbs regulate the redox balance by decreasing the levels of MDA and increasing the level of GSH.
Completion Surgery after Non-Curative Local Resection of Early Rectal Cancer
Authors: Baral Joerg Ernst Mathias , Kouladouros Konstantinos
Published: May 2024

Background: The expanding indications of local – endoscopic and transanal surgical – resection of early rectal cancer has led to their increased popularity and inclusion in the treatment guidelines. The accuracy of the current diagnostic tools in identifying the low-risk T1 tumors that can be curatively treated with a local resection is low, and thus several patients require additional oncologic surgery with total mesorectal excision (TME). An efficient clinical strategy which avoids overtreatment and obstacle surgical procedures is under debate between different disciplines. Summary: Completion surgery has comparable outcomes to primary surgery regarding perioperative morbidity and mortality but also recurrence rates and overall survival. However, local scarring in the mesorectum can make mesorectal excision technically challenging, especially after full-thickness resections, and has been associated with increased rates of permanent ostomy and worse quality of the TME specimen. This risk seems to be lower after muscle-sparing procedures like endoscopic submucosal dissection, which seem to show a benefit in comparison to full-thickness resections. Key Messages: Completion surgery after non-curative local resection of gastrointestinal malignancies is safe and feasible. Full-thickness resection techniques can cause scarring of the mesorectum; therefore, muscle-sparing procedures should be preferred.
ROP: 80 Years after Its Detection – Where Do We Stand and How Long Will We Continue to Laser?
Authors: Hellström Ann , Smith Lois E.H. , Hård Anna-Lena
Published: May 2024

Background: Retinopathy of prematurity (ROP), a potentially blinding disease, is increasing worldwide because of the increased survival of extremely preterm and preterm infants born where oxygen monitoring and ROP screening programs are insufficient. Repeated retinal examinations are stressful for infants, and laser photocoagulation treatment for sight-threatening ROP is destructive. The use of anti-VEGF agents instead of lasers is widespread but requires a long-term follow-up because of late recurrence of the disease. In addition, the optimal anti-VEGF agent dosage and long-term systemic effects require further study. Summary: Interventions preventing ROP would be far preferable, and systemic interventions might promote better development of the brain and other organs. Interventions such as improved oxygen control, provision of fresh maternal milk, supplementation with arachidonic acid and docosahexaenoic acid, and fetal hemoglobin preservation by reducing blood sample volumes may help prevent ROP and reduce the need for treatment. Free readily available online tools to predict severe ROP may reduce unnecessary eye examinations and select, for screening, those at a high risk of needing treatment. Key Messages: Treatment warranting ROP is a sign of impaired neurovascular development in the central nervous system. Preventative measures to improve the outcomes are available. Screening can be refined using tools that can predict severe ROP. Laser treatment and anti-VEGF agents are valuable treatment modalities that may complement each other in recurrent ROP.
Major Depression as a Disorder of the Narrative Self: A Qualitative Study
Authors: Mancini Milena , Esposito Cecilia Maria , Estradé Andrés , Rosfort René , Fusar-Poli Paolo , Stanghellini Giovanni
Published: May 2024

Introduction: Abnormal self-experiences are a common feature of major depression despite their absence from current diagnostic manuals. Current diagnostic criteria leave us with an impoverished conception of depressive disorders, and they fail to exploit the diverse experiential alterations that might be useful for understanding and diagnosing patients, and last but not least for explaining the aetiology of these disorders. Although some phenomenological descriptions of abnormal self-experiences in major depression are available, further research is needed to validate these through detailed clinical interviews. Methods: To characterize these phenomena in more detail and to verify and consolidate previous accounts, we conducted a qualitative study using the Consensual Qualitative Research method. Results: Our findings identified three categories of abnormal self-experiences: (1) impossibility to project oneself forward, (2) not recognizing one’s self, and (3) losing control on one’s self. Conclusion: Before delving into these results, we briefly described how the self is conceptualized in phenomenological psychopathology and explored in the literature on the self-experience in major depression. After discussing our results in the light of recent and contemporary phenomenological literature, we suggest that the inability to recognize otherness as part of oneself – which is the core of depressive experiences – ends in specific symptoms of depersonalization that differ from schizophrenic ones. We conclude that the self-experience, and in particular narrative identity, is central to the development and maintenance of depression.
Relation Extraction in Underexplored Biomedical Domains: A Diversity-optimized Sampling and Synthetic Data Generation Approach
Authors: Delmas Maxime , Wysocka Magdalena , Freitas André
Published: May 2024

The sparsity of labeled data is an obstacle to the development of Relation Extraction (RE) models and the completion of databases in various biomedical areas. While being of high interest in drug-discovery, the literature on natural products, reporting the identification of potential bioactive compounds from organisms, is a concrete example of such an overlooked topic. To mark the start of this new task, we created the first curated evaluation dataset and extracted literature items from the LOTUS database to build training sets. To this end, we developed a new sampler, inspired by diversity metrics in ecology, named Greedy Maximum Entropy sampler (https://github.com/idiap/gme-sampler). The strategic optimization of both balance and diversity of the selected items in the evaluation set is important given the resource-intensive nature of manual curation. After quantifying the noise in the training set, in the form of discrepancies between the text of input abstracts and the expected output labels, we explored different strategies accordingly. Framing the task as an end-to-end Relation Extraction, we evaluated the performance of standard fine-tuning (BioGPT, GPT-2, and Seq2rel) and few-shot learning with open Large Language Models (LLMs) (LLaMA 7B-65B). In addition to their evaluation in few-shot settings, we explore the potential of open LLMs as synthetic data generators and propose a new workflow for this purpose. All evaluated models exhibited substantial improvements when fine-tuned on synthetic abstracts rather than the original noisy data. We provide our best performing (F1-score = 59.0) BioGPT-Large model for end-to-end RE of natural products relationships along with all the training and evaluation datasets.

The (Im)Possibility of Persistence? – Najm al-Dīn al-Ṭūfī’s (d. 716/1316) Atomistic Argumentation for the Probative Value of istiṣḥāb al-ḥāl
Authors: Kurnaz Serdar
Published: May 2024

Istiṣḥāb al-ḥāl, the presumption of the persistence of a state or ruling, is a disputed source within Islamic jurisprudence. For some scholars, it is one of the main sources of Islamic law. Many juristic principles are based on istiṣḥāb. The Hanbali scholar al-Ṭūfī (d. 716/1316) follows this idea in Sharḥ Mukhtaṣar al-Rawḍa and holds that istiṣḥāb is the fourth source of law after the Quran, Sunna, and Consensus. Al-Ṭūfī argues for the validity of istiṣḥāb with regard to a physical theory in kalām known as atomism. He discusses the possibility of continuation in existence. In his view istiṣḥāb is based on the principle that persistence/continuation (baqāʾ) is an accident (ʿaraḍ) that is not re-created in each moment in contrast to kalām atomism, which postulates that accidents are re-created constantly. This article presents al-Ṭūfī’s original approach to the validity of istiṣḥāb that guarantees the continuous existence of a state and ruling.
The impact of ciliate nutrition on aquatic ecosystems
Authors: Mandal Fatik Baran
Published: May 2024

Ciliate interactions including mode of nutrition contribute significantly to freshwater and marine ecosystems. Ciliates associations with their bacterial communities, and symbionts have crucial contributions to biomass productivity, transfer of nutrients to higher trophic levels and thus to sustain the ecosystems. The mixotrophic and heterotrophic ciliates are crucial in nutrient cycling by increasing nitrogen, phosphorus, and sulphur. Bacterial predator ciliates regulate the bacterial population and function as bioindicators. Endosymbionts in ciliates illustrate the incorporation of photosynthesis, nitrogen fixation and recycling, and methanogenesis, into ciliate hosts by endosymbionts. Endosymbiosis represents an evolutionary strategy of protists to acquire novel biochemical functions. Herein, I briefly give an account for the impact of ciliate nutrition on aquatic systems.
Making a Case for Trade: Shi Shipiao’s Map of the Eastern and Southern Oceans
Authors: Papelitzky Elke
Published: May 2024

In the early eighteenth century, the Kangxi emperor was presented with two maps in Chinese, one each from the officials Gioro Mamboo and Shi Shipiao. The maps showed southern China and Southeast Asia and were based on Dutch charts. The officials presented the maps at a time when the emperor had recently issued a law restricting Chinese trade in Southeast Asia. The map presented by Shi Shipiao adds information about sailing routes and export goods that were subject to the trade restrictions imposed by the emperor. This article argues that rather than being intended to provide a representation of seafaring knowledge, Shi aimed to use the map he presented to convince the emperor to lift the restrictions he had imposed on trade. This therefore provides an example of how maps could be used for political ends. In contrast to many other Chinese maps influenced by European sciences, these two maps show no Jesuit involvement but resemble the Selden Map as well as Japanese and Buginese charts, representing a maritime perspective in the history of knowledge exchange.

Markers in the polytene chromosomes of freshwater Chironomus Meigen (Diptera, Chironomidae) species
Authors: MICHAILOVA PARASKEVA
Published: May 2024

Based on the morphology of the polytene chromosomes, 21 species of the genus Chironomus Meigen from Bulgaria have been identified. Original pictures of the polytene chromosomes are presented for each species. “Basic” sequences were determined for each arm of the polytene chromosomes which are used to determine the corresponding arms of the chromosomes, and the cytocomplex to which the species belongs. The species are distributed in five cytocomplexes: thummi, pseudothummi, parathummi, lacunarius and modified thummi cytocomplexes. Marker sequences have been revealed on chromosome G that are proposed as a species identifier. Cytogenetic characters by which homosequential species of the genus Chironomus can be distinguished are discussed. This study emphasizes the importance of polytene chromosomes for the taxonomy of the species of Chironomus.

Doing Genders: Partner’s Gender and Labor Market Behavior
Authors: Jaspers Eva , Mazrekaj Deni , Machado Weverthon
Published: May 2024

Partnered men and women show consistently gendered patterns of labor market behavior. We test whether not only a person’s own gender, but also their partner’s gender shapes hours worked. We use Dutch administrative population data on almost 5,000 persons who had both male and female partners, whose hours worked we observe monthly over 15 years. We argue that this provides a unique setting to assess the relevance of partner’s gender for labor market behavior. Using two-way fixed effects and fixed-effects individual slopes models, we find that both men and women tend to work more hours when partnered with a female partner compared to a male partner. These results align with our hypothesis that a partner’s gender influences labor market behavior. For women, we conclude that this finding may be (partly) explained by marital and motherhood status. Additionally, we discovered that women decrease their hours worked to a lesser extent when caring for a child if they have a female partner. Finally, we found that for men, the positive association between own and partner’s hours worked is weaker when one has a female partner, indicating a higher degree of specialization within these couples.
What Men Want: Parties’ Strategic Engagement With Gender Quotas
Authors: Clark Julia Michal , Blackman Alexandra Domike , Şaşmaz Aytuğ
Published: May 2024

Women’s under-representation, particularly in political leadership, remains an important issue globally. Tunisia’s 2018 municipal elections included the adoption of strict gender quotas that resulted in near-parity of male and female elected councilors. Despite this achievement for descriptive representation, fewer than 20% of mayors—selected from among elected list-heads—were women. We argue that this gender gap in council leadership is the result of parties’ strategic engagement with the quota laws. Using election data, an original survey of candidates, and interviews, we demonstrate that parties systematically placed female-headed lists in their weakest districts, placing female candidates at a disadvantage during the mayoral selection process. We provide evidence that these behaviors were motivated by a strategy to avoid “displacing” men in established political networks. This research highlights the role that party elites play in maintaining the existing political bargain at the expense of underrepresented groups, even where strict quotas are adopted.
“Canada is a Big Deal Here”: The eFP Battle Group and Host Nation Public Opinion
Authors: Banka Andris , Bussmann Margit
Published: May 2024

Does personal contact between allied service members and local citizens result in greater public acceptance of foreign military presence? To what extent do members of the host nation's domestic society assess favorably the forward deployment of allied military personnel on their own national territory? Substantial scholarly literature has probed these types of questions in the context of US globe-spanning military deployments. This study, however, departs from the US-centric approach and focuses on the deployment of a middle power. In the presented analysis, we examine the Canadian approach to “winning hearts and minds” in Latvia. In 2023, upwards of 800 Canadian troops were stationed in Latvia. Using original survey data, we measure local citizens' attitudes towards the Canadian-led battlegroup. Our results speak to the fact that Canadian and other foreign armed forces' presence in Latvia is generally accepted by the wider society. Despite Moscow's active attempts to cultivate anti-NATO sentiments, the Latvian public welcomes the stationing of Canadian troops on the country's soil.
Exploring Post-Traumatic Growth Among Young Adults Coping With Parental Loss: The Role of Resilience and of Willingness to Seek Psychological Help
Authors: Elyoseph Zohar , Levi-Belz Yossi , Shimoni Yoav , Levkovich Inbar
Published: May 2024

This study examined the roles of resilience and willingness to seek psychological help in influencing Post-Traumatic Growth (PTG) among 173 emerging adults who experienced parental loss during their school years. A positive relationship was found between resilience, the willingness to seek psychological help, and PTG. Participants who endured loss over five years prior manifested increased PTG (New-Possibilities, Spiritual Change, and Appreciation of Life sub-scales) relative to those with more recent losses. The multiple regression model was notable, accounting for 33% of the variance in PTG. Both resilience and the willingness to seek psychological help assistance significantly predicted PTG, surpassing other predictors in the model. It is worth noting that the type of loss, whether sudden or anticipated, did not alter PTG levels. In essence, this study underscores the enduring positive psychological impact of parental loss on emerging adults, highlighting the critical need for comprehensive psychological resources and support for such individuals.
Historicising the Spiritual–Political Fold in Asceticism: The Sree NarayanaGurukulamand Social Change
Authors: Cybil K. V.
Published: May 2024

Narayana guru (1856–1928), in whose name the Sree Narayana Dharma Paripalana Yogam was formed in early twentieth-century Kerala, challenged the claim that brahmins made to the exclusive possession of the wisdom and practices of the Vedic and Vedantic texts. Guru did this by preaching a variant of Upanishadic philosophy and establishing temples in which he installed the deities. Drawing mainly upon the writings of a disciple, Nataraja guru (1895–1973), this article explores the links between the spiritual and the political through a historicising perspective.
Uncovering the Hidden Intangible Factors of Hotel Employees’ Turnover Intention During COVID Phenomenon
Authors: Chaichi Kamelia , Zawawi Dahlia , Aziz Yuhanis Abdul , Leong Mei Kei
Published: May 2024

The extant literature on hospitality and human resource management has not yet uncovered the hidden intangible chain of employee turnover intention, particularly in the hotel context. A theoretical framework was developed by applying the tenets of the theory of planned behaviour, social cognitive theory and the multi-dimensional commitment model. More specifically, this study investigated the impact of staff core personality (core confidence traits and core self-evaluation) on employees’ positive attitudes towards the organization, ultimately decreasing employee turnover intention. Further, the study scrutinized the moderating impact of organizational commitment dimensions in the extended model and the links that were missing in prior literature. It employed a self-administered survey and obtained 300 usable responses. The data were analysed through partial least squares structural equation modelling (PLS-SEM) software. The results revealed that all the core personality factors (CSE and core confidence traits, including resilience, hope and optimism) and self-efficacy significantly affect the staff’s positive attitude. Moreover, the study established the moderating impact of affective commitment and continuous commitment on the connection between attitude and employees’ intention to leave the organization. This article recommends several practices that hotel human resource managers can utilize to reduce employee turnover intention and upsurge the sustainability of the hotel industry.
Optimisation of thermal regime and consolidation properties of high-silica magnesium-containing pellets
Authors: Cai Qiuye , Zhang Jianliang , Wang Yaozu , Zhang Guohua , Ma Liming , Jiang Huiqing , Liu Zhengjian
Published: May 2024

An in-depth study on the preparation process of high-silica magnetite magnesium pellets based on a grate-rotary kiln process is of great significance for promoting the utilisation of low-grade magnetite resources. When the magnetic hematite ratio is 30% and the proportion of magnesia is 1.5%, the performance of green pellets is the best. The preparation of high-silica magnesium pellets requires two stages of grate preheating for additional heating, and the appropriate preheating system is 1150°C for 15 min. The suitable magnetic hematite mixture ratio of pellets should not exceed 30%, and the reasonable magnesia ratio should not exceed 1.5%. Otherwise, the preheating temperature should be further increased, or the preheating time should be extended. The suitable roasting temperature is low, only 1225°C for 15 min, and the pellet strength can reach more than 2365N. Magnetic hematite and added magnesium flux inhibited the continuous crystallisation consolidation property in the pellet. The high SiO2 content in the gangue of high-silica magnetite impedes the recrystallisation consolidation of Fe2O3 particles in the pellet. At the same time, the primary Fe2O3 in the magnetic hematite mixed ore is less reactive than the new Fe2O3 in the magnetite oxidation. With the roasting process, the magnesium ferrite content in the pellet increases, and the recrystallisation consolidation is inhibited, so the grate-rotary kiln process to produce high-silica magnesium-containing pellets is suitable to use a higher preheating temperature to meet the requirements of grate-rotary kiln pellet strength.
Research on the interaction of burden gangue phases based on thermodynamic calculation
Authors: Liu Zhiwei , Wang Qiong , Pan Yuzhu
Published: May 2024

The melting drip test and single-particle test show that there is an interaction between the gangue phases of different property burdens. Finally, the primary slag forms with uniform ingredients. This article analyses the melting and interaction mechanism of gangue phases in different properties of burdens by using FactSage thermodynamic calculation software and expounds on the impact of interaction on smelting under different process conditions. The results show that due to the different phase compositions, the liquid phase ratio of the gangue phase in pellet ore is higher than that in sinter ore. The mixed primary slag composed of pellets and sintered gangue phases has a higher liquid phase ratio than that of a single sintered gangue phase, which is also higher than the weighted average of the liquid phase ratios of pellets and sintered gangue phases, indicating that interaction can promote the melting of refractory sintered gangue phases. The liquid phase ratio of the gangue phase increases with the increase of FeO content. Under current process conditions, using a high basicity sinter with an acidic burden is more reasonable than using a flux burden. In the future, high reduction potential blast furnaces such as oxygen blast furnaces and hydrogen-rich blast furnaces can use acidic and flux burden.
Enhancing engineering education: Investigating the impact of mobile devices on learning in a thermal-fluids course
Authors: Bakic Maeve , Pakala Krishna , Bairaktarova Diana , Bose Devshikha
Published: May 2024

The COVID-19 pandemic has affected learning at all levels; particularly, in higher education, where levels of independence and self-motivation are required during distance learning. In engineering, distance learning adds another degree of difficulty to an already complex field. Comprehension in engineering requires the repeated use of diagrams, high-level charts, and practice problems. Mobile devices, combined with a technology-enhanced curriculum, provide an excellent platform for learning in engineering as it allows for clear illustration and the transfer of complex ideas at any time and place. In alignment with the social-constructivist framework, these facets of mobile technology provide additional avenues for student engagement and the extension of learning goals. This study utilized the Triple E Framework and a mixed methods approach to investigate the impact of mobile devices on engineering students’ learning in a thermal-fluids course. The overall aim was to understand how mobile technology, combined with a technology-enhanced curriculum, impacts engineering students’ engagement, enhancement, and extension of learning. Findings reveal that students perceived increased levels of engagement when utilizing mobile devices in their learning practices. However, instructional methods were identified to be the key factor leading to engagement. A small effect size of 0.37 was noticed, and a post hoc power analysis resulted in a test power of 0.55. Though a significant difference between students who did and did not utilize mobile devices was not apparent, students with university loaned tablets (iPads) had a larger increase in learning than students without. This paper is based on the author's master's thesis titled “Affordances of Mobile Technology to Facilitate Learning in Undergraduate Thermal-Fluid Sciences,” the represented data reflects content from the same.
Of dinosaurs and intergenerational culture wars: Dinomania, nostalgia, and the ‘missionary lizards’ of young earth creationism
Authors: Laurence Alison
Published: May 2024

For over a century, dinosaurs have drawn crowds to natural history museums, where visitors learn about evolution and deep time. Towards the end of the twentieth century, certain young earth creationists began using dinosaurs as ‘missionary lizards’ to attract audiences and promote a biblically literal interpretation of the planetary past. Though long extinct, dinosaurs are thus significant figures in the ongoing U.S. culture wars. This article demonstrates how the Creation Museum in Kentucky uses dinosaur displays to legitimate a young earth and anti-evolution worldview. It also analyses how mainstream science museums and creation science museums alike leverage dinomania and a related sentiment, nostalgia, to draw crowds and create potent emotional experiences. A comparison of marketing materials for the Creation Museum and the Smithsonian's Deep Time fossil hall, both of which target children and their families, show how dinosaurs are intergenerational artifacts that connect people to personal and planetary pasts.
From critical theory to critical fabulism: Aesthetics in a minor key
Authors: Ryan Kevin
Published: May 2024

In this essay to mark the centenary of the Frankfurt School, I situate the (his)story of domination between critical theory and critical fabulism. The version of this (his)story crafted by the first generation of Frankfurt School thinkers is anchored in the idea of ‘the masses’, and in the first part of the article, I track this through the work of Theodore Adorno, drawing on Grant Kester's writings on ‘exculpatory critique’. The second part of the paper pivots to Saidiya Hartman's method of critical fabulism, which affords a way of refiguring the relationship between aesthetics and politics while also refusing the idea of the masses. In contrast to Adorno’s Aesthetic Theory, which is an all-or-nothing wager with a future currently foreclosed and forever deferred, in the world(s) that Hartman fabulates, the revolution is always already happening.

Background

Nurses experience elevated rates of operational stress injuries (OSIs). This can necessitate taking leave from work and subsequently engaging in a workplace reintegration process. An unsuccessful process can have long term impacts on a nurse's career, affecting the individual, their family, and broader community, while contributing to nursing shortages. A knowledge gap regarding the workplace reintegration of nurses experiencing mental health challenges, impedes the development and implementation of initiatives that might increase the success of nurses reintegrating into the workplace. This scoping review explored the existing literature concerning workplace reintegration for nurses experiencing OSIs.

Methods

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) reporting guidelines were utilized. Three key search terms across six databases were employed followed by a qualitative content analysis of the resulting literature.

Results

Eight documents were included. The literature exhibited high heterogeneity in objectives, content, and article types. The content analysis revealed five themes: (1) recognizing stigma, (2) elements of successful workplace reintegration, (3) considerations for military nurses, (4) considerations for nurses with substance use disorders, and (5) gaps in the existing literature.

Conclusion

A paucity of programs, policies, procedures, and research exists regarding workplace reintegration for nurses facing mental health challenges. It is imperative to recognize that nurses may experience OSIs, necessitating mental health support, time off work, and operationally/culturally-specific assistance in returning to work. Innovative and evidence-based approaches to workplace reintegration are needed to enhance the retention of a skilled, experienced, compassionate, and healthy nursing workforce.

Authors: Al-Hammouri Mohammed Munther
Published: May 2024

Purpose: The current study aimed to examine the role of the dominant spiritual and religious coping modality on health-related variables and determinants, including stress overload, mindfulness, and impulsivity, among nursing students. Methods: A cross-sectional design was used to achieve the study goal. The authors recruited 1199 nursing students. The results showed that the mean for positive spiritual and religious coping was higher compared to negative spiritual and religious coping. Results: In the current study, 73.3% of nursing students predominantly used positive spiritual and religious coping compared to 17.6% in the neutral group and 9.1% in the negative spiritual and religious coping group. Positive spiritual and religious coping was positively correlated with mindfulness and stress overload and negatively correlated with impulsivity. According to the ANOVA results, students with positive spiritual and religious coping tended to have a significantly higher stress overload, higher mindfulness, and lower impulsivity compared to the neutral and negative spiritual and coping groups. Negative spiritual and religious coping group significantly differed from the neutral groups only in terms of impulsivity. Conclusion: The current study's findings help nursing students by determining dominant spiritual and religious coping modalities and provide valuable information in directing counseling efforts. Results and implications were discussed.

The analysis of magnetohydrodynamic (MHD) Marangoni fluid flow, heat, and mass transport over a disk is considered in this article. The fluid is assumed to pass radially over a stretching disk. Suction/blowing at the boundary, internal heat generation/absorption, and a first-order chemical reaction are also considered. By using appropriate similarity transformations, the governing nonlinear partial differential equations (PDEs) are transformed into ordinary differential equations (ODEs). These ODEs along with the appropriate boundary conditions for the model are solved numerically by a shooting technique using MATHEMATICA software. The obtained results are compared with the available results in the literature for some special cases. The effects of the magnetic parameter, the Marangoni number, Marangoni ratio parameter along with the other pertinent parameters on fluid flow, heat and mass transport are analyzed and discussed in detail. It is noted that higher magnetic field depresses the fluid velocity whereas the fluid temperature and fluid concentration are uplifted with an increase in the magnetic field parameter. A quite opposite behavior is observed for Marangoni number. Marangoni ratio parameter boosted the fluid velocity as well as the fluid concentration and the temperature. Also externally applied suction significantly affects the fluid behavior. Increasing chemical reaction parameter reduces the fluid concentration. It is observed that a maximum increase in the Nusselt number occurs for Marangoni parameter Ma, which is 34.75595% when the suction/injection parameter s = 0.5. Also, for Marangoni ratio parameter Ra, a maximum increase in Nusselt number occurs, which is 6.7884% when suction/injection parameter s = 0.5.
Impact of electro-osmotic, activation energy and chemical reaction on Sisko fluid over Darcy–Forchheimer porous stretching cylinder
Authors: Nisha S Siraj , De Poulomi
Published: May 2024

This study provides numerical solution for two-dimensional electro-osmotically motivated electro-magneto-hydrodynamic Sisko fluid through an elongating porous cylinder. The electro-osmotic, activation energy with chemical reaction are also interpreted for this flow model. The numerical equations that govern this flow problem are renewed into dimensionless form by applying appropriate transformations exploiting Runge–Kutta–Fehlberg fifth order through shooting technique method. The after-effects are illustrated as graphs for the concerned physical parameters and their impact on convection and conduction is also studied. The velocity rises for electro-osmotic parameter whereas drops for magnetic and porous parameter. The temperature shows an increasing profile for the curvature, electric and thermal conductivity parameter while decreases for Prandtl number. The concentration of nanoparticles in the fluid boosts for activation energy but deflates for curvature parameter. The present findings appear to be in good accord when compared to earlier published studies. Numerous opportunities and applications are presented by applying electro-osmotic forces to non-Newtonian fluid flow, especially in the fields of nanotechnology, electro-kinetics and micro-fluids. The current study can be applied to design effective electro-magnetic devices, particularly in certain thermal transport characteristic regime. The main findings demonstrate the great utility of electro-osmosis in micro-fluidic devices, chemical analysis, soil analysis and cement slurries for managing flow and heat transmission.
Design and analysis of bending-active configurations through an initial flat-cut pattern based on the curvature lines
Authors: Fathollahi Armin , Beatini Valentina
Published: May 2024

Bending active structures involve the deformation of originally flat structures during the erection process. These structures offer a promising approach to enhance design sustainability. However, despite advancements in structural computational methods, their implementation is still limited. This paper examines the constraints associated with this design approach from a designer’s perspective and proposes potential solutions. From this analysis, a design method is developed that utilizes additive manufacturing to explore different solutions during the concept stage. Prior to the form-finding process, a flat, variable-density pattern is created within a parametric environment. This pattern, referred to as the “Soft Pattern based on Control Points” (SPSCP), incorporates multiple design variables to accommodate diverse design requirements. In this preliminary study, we compare the impact of varying the design parameters on a small-scale model, as observed by the naked eye, and through finite element analysis.
Critical Review of Use of Medical Versus Social Model for Identification of Learning Disabilities
Authors: Kapoor Geetika , Kaul Sakshi
Published: May 2024

The process of identification of specific learning disability (SLD), in India, is dominated by the medical model with strong emphasis on an IQ score of 85 and above, as an important inclusion criterion. In addition, there is minimal emphasis on tracking learning history for quality interventions. Only parent reports that they have been teaching the child and child’s attendance of a formal school since the beginning of their scholastic journey are taken as indicators that the child has been taught the foundational skills of reading, writing, and maths but has failed to show mastery. The focus of the research paper is to critically review the medical model and social model to be able to make suggestions of best fit. The perspective is to be able to look at learning disability from the point of functionality and bring forth the options that can assist specific cases of scholastic underachievement. The present paper outlines the problems with following the IQ score driven, medical model while addressing an educational problem. Further, suggestions are made toward creating a social, problem-solving approach toward identification of SLD that will focus more on teaching toward closing of scholastic lags and identification of specific needs and supports that learners need to successfully complete their schooling, with confidence and pride.
