In Praise of Happy Endings: Precarity, Sustainability, and the Novel
Authors: Levine Caroline 
Published: February 2023

AbstractOpen-endedness is one of the most pervasive and enduring values in literary studies. Critics of all stripes have condemned teleology on both aesthetic and political grounds. This essay makes the paradoxical case that in an era of mass precarity, this insistence on openness has reached its limit. It is now blocking the kinds of political action that will be necessary to slowing the pace of climate change and building material conditions for collective flourishing. This is a moment for novel critics, then, to rethink our relationship to endings. The nineteenth-century realist novel is particularly interesting in this respect, since it took the question of ongoing material survival especially seriously and used endings to mark a shift from narratable, unstable plotted action to stable routines that extend predictably into the future. In these plots of precarity, happy endings function not as closure or completion but as thresholds to sustainability. This essay ends with two twentieth-century fictions—Bessie Head's 1974 A Question of Power and Leslie Feinberg's 1993 Stone Butch Blues—that conclude by combining the pleasures of material predictability and plenty with workable models of social relations that could help to guide political action in the climate crisis.
Cosmopolitical Perplexities
Authors: Jensen Casper Bruun 
Published: February 2023

Abstract
Over the last decade, the Anthropocene has overrun the discourses of the humanities and social sciences. Remarkably, two of the most astute commentators, the cross-disciplinary theorist Barbara Herrnstein Smith and the unorthodox philosopher Isabelle Stengers, find inspiration for grappling with these issues in the same apparently odd place: the work of the Polish microbiologist and comparative epistemologist Ludwik Fleck. The first part of this essay explores the role of Fleck's radical constructivism in Smith's analyses of perplexing Anthropocene realities and Stengers's arguments for slowing down science and learning to “compose with Gaia.” In conjunction, they generate a pattern of speculative, conceptual, practical, and political motifs for dealing with changing climates. The second half of the essay uses those insights to test a divergent series of proposals for how to conceive science, politics, theory, and environmental relations in the Anthropocene.
Reproductive genomics of the mouse: implications for human fertility and infertility
Authors: Garretson Alexis , Dumont Beth L. , Handel Mary Ann 
Published: February 2023

ABSTRACTGenetic analyses of mammalian gametogenesis and fertility have the potential to inform about two important and interrelated clinical areas: infertility and contraception. Here, we address the genetics and genomics underlying gamete formation, productivity and function in the context of reproductive success in mammalian systems, primarily mouse and human. Although much is known about the specific genes and proteins required for meiotic processes and sperm function, we know relatively little about other gametic determinants of overall fertility, such as regulation of gamete numbers, duration of gamete production, and gamete selection and function in fertilization. As fertility is not a binary trait, attention is now appropriately focused on the oligogenic, quantitative aspects of reproduction. Multiparent mouse populations, created by complex crossing strategies, exhibit genetic diversity similar to human populations and will be valuable resources for genetic discovery, helping to overcome current limitations to our knowledge of mammalian reproductive genetics. Finally, we discuss how what we know about the genomics of reproduction can ultimately be brought to the clinic, informing our concepts of human fertility and infertility, and improving assisted reproductive technologies.
Deconvolution from Wave-Front Sensing Enhanced with Blind Deconvolution
Authors: Dayton David , Sandven Steve , Gonglewski John 
Published: February 2023

INTRODUCTION
Deconvolution from Wave-Front Sensing (DWFS) has been investigated both through laboratory and field experiments as a method to produce high resolution images from ground based telescopes.1,2,3 This technique has sometimes been referred to as Speckle Holography. With this technique a short exposure focal plane image is recorded simultaneously with an estimate of the atmospheric wave-front. The wave-front estimate is used to calculate an optical transfer function (OTF) for the atmosphere. This OTF estimate is then used in a deconvolution algorithm to correct the focal plane image. A synoptic sketch of a DWFS instrument is shown in figure 1.

Published: February 2023

Background
As untreated visceral leishmaniasis (VL) is fatal, reliable diagnostics are pivotal for accurate treatment allocation. The current diagnostic algorithm for VL in Ethiopia, which is based on the rK39 rapid diagnostic test and microscopy of tissue smears, lacks sensitivity. This probably leads to missed cases and patients not receiving treatment.

Methodology
We conducted a retrospective study on stored microscopically negative spleen and bone marrow smears from suspected VL patients collected at the Leishmaniasis Research and Treatment Center (LRTC) in Gondar, northern Ethiopia between June 2019 and November 2020. Sociodemographic, clinical and treatment data were collected and samples were tested by real-time PCR targeting kinetoplast DNA.

Principle findings
Among the 191 eligible samples (135 spleen and 56 bone marrow) with a microscopically negative and valid PCR result, 119 (62.3%) were positive by PCR, although Ct values for some were high (median 33.0). Approximately three quarters of these undiagnosed primary VL (77.3%) and relapse (69.6%) patients did not receive antileishmanial treatment. Of the 56 microscopically negative bone marrow samples, 46 (82.1%) were PCR positive, which is considerably higher compared to the microscopically negative spleen samples, for which 73 out of 135 (54.1%) were PCR positive. The odds of being PCR positive were significantly higher for bone marrow aspirates and higher when white blood cell values were lower and splenomegaly (in cm) was more pronounced.

Conclusions
This study demonstrates that a lot of suspected VL patients remain undiagnosed and untreated. This indicates the urgent need for better diagnostics for VL in the East-African region. The outcomes of PCR positive should be closely monitored and treatment should be provided if the patient deteriorates. In resource limited settings, implementation of PCR on bone marrow aspirate smears of patients with low WBC values and splenomegaly could lead to considerable improvements in patient management.
Efficacy and safety of vapocoolant spray for vascular puncture in children and adults: A systematic review and meta-analysis
Authors: Wang Lan , Fang Liu , Zhou Yang , Fang Xiaofeng , Liu Jiang , Qu Guiyu 
Published: February 2023

ObjectiveThe aim was to evaluate the effectiveness and safety of the vapocoolants for vascular puncture in children and adults.MethodThe search was carried out in PubMed, Web of Science, Embase and The Cochrane Library, from inception to March 2022. Randomized controlled trials comparing vapocoolants to control conditions for participants received intravenous cannulation or arterial puncture were included. Two reviewers independently performed selection of studies, data extraction, and assessment of risk of bias. The analysis was performed using fixed or random-effects model with mean differences or standardized mean difference and risk ratios.ResultsA total of 25 studies involving 3143 participants were included. Compared with control conditions, vapocoolants may not decrease the pain of patients with arterial puncture (SMD = -0.36, 95% CI = -0.92 to -0.19,P= 0.20), but may more effectively relieve pain for adults received vein puncture (SMD = -0.65, 95% CI = -0.85 to -0.45,P< 0.00001). The application of vapocoolant increased the procedural difficulty of medical personnel (RR = 2.49, 95% CI = 1.62 to 3.84,P<0.000 1) and participants were more willing to use the spray in the future (RR = 1.88, 95% CI = 1.34 to 2.64,P= 0.0002). There was no significant difference for the first attempt success rate of the procedure and the occurrence of adverse events.ConclusionsVapocoolant spray may relieve pain in adults received vein puncture and cannot cause severe side effects, but is ineffective in children. It also had no effect on patients with arterial puncture. In addition, the application of spray increases procedural difficulties for medical professionals, but does not decrease first attempt success rate, and many patients would like to use the spray again for pain relief in the future. Thus, more rigorous and large-scale studies are needed to determine its effectiveness in vascular access.
Can social enterprises aid sustainable development? Evidence from multi-stage investigations
Authors: Bansal Sanchita , Garg Isha , Vasa László 
Published: February 2023

Background
Social enterprises must balance between profitability and sustainability. The impetus on sustainability grew further after the adaption of the SDG agenda by the United Nations (UN).

Objective
This paper examines the role of social enterprises in helping attain sustainable development goals in India.

Research design
This multi-stage paper comprises three studies directed at scale development, scale refinement, pre-testing, and construct validity. The scale development stage is conducted through a combination of extensive literature review and focused group discussions. Expert discussions and item-reduction techniques have been used in the second stage aimed at scale refinement and pre-testing. The third stage of testing construct validity is carried out through Partial Least Square–Structural Equation Modelling (PLS-SEM).

Results
The findings suggest that all the competencies of social enterprises identified in the study i.e. social mission, collaborative networks, innovation, financial viability and level of scalability significantly impact sustainable development.

Conclusion
Because the goals of social enterprises and the Sustainable Development Goals (SDGs) are mutually reinforcing and complementary, the study suggests that social enterprises have a lot of potential for achieving the SDGs. The study also suggests future research directions and policy implications that can be replicated in other countries.
Global inequity creates local insufficiency: A qualitative study of COVID-19 vaccine implementation challenges in low-and-middle-income countries
Authors: Haldane Victoria , Ariyarajah Archchun , Berry Isha , Loutet Miranda , Salamanca-Buentello Fabio , Upshur Ross E. G. 
Published: February 2023

Introduction
The COVID-19 pandemic has amplified pre-existing challenges to health promotion and care across the world, and particularly in low- and middle-income countries (LMICs). This qualitative study draws on data from a panel of immunisation experts and uses a novel framework of vaccine delivery domains to explore perspectives from those who live and work in these settings on the challenges to implementing COVID-19 vaccine programs in LMICs.

Methods
We conducted a thematic content analysis of 96 participant free text replies to questions from Round I of a three-round Delphi consensus study amongst global experts on COVID-19 vaccine implementation.

Results
Participant responses highlighted challenges to vaccine program implementation including issues related to equity; governance, decision-making, and financing; regulatory structures, planning, and coordination; prioritisation, demand generation, and communication; vaccine, cold chain, logistics, and infrastructure; service delivery, human resources, and supplies; and surveillance, monitoring, and evaluation.

Conclusion
We reflect on our findings in light of global efforts to address vaccine inequity and emphasise three key areas salient to improving vaccination efforts during novel infectious disease outbreaks: 1) Ensuring safe and sustainable service delivery in communities and at points of care; 2) Strengthening systems for end-to-end delivery of vaccines, therapeutics, diagnostics, and essential supplies; 3) Transforming structural paradigms towards vaccine equity.
Undergraduate e-learning programmes in health professions: An integrative review of evaluation standards in low- and middle-income countries
Authors: Mutua Moses M. , Nyoni Champion N. 
Published: February 2023

Background
Before the Coronavirus COVID-19, universities offered blended learning as a mode of study. However, with the closure of all educational institutions, after the pandemic, most of these institutions were required to transition to e-learning to support continuous student learning. This transition was challenging to most institutions, as there were no standards to ensure the quality of e-learning. During this literature review, the researcher aimed to explore relevant literature and provide insight into the standards for undergraduate e-learning programmes in the health professions.

Design
An integrative review of literature.

Data sources
Online databases MEDLINE, CINAHL with full text, Academic search ultimate, APA PsycInfo, ERIC, Health Source: Nursing/academic edition, CAB abstracts, Africa-wide information, Sociology source ultimate, and Communication and Mass media complete were searched.

Materials and methods
Studies pertaining to low- and middle-income countries (LMICs) on standards in evaluating undergraduate e-learning programmes in health professions, published between January 2010 to June 2022, were considered. A two-step process was followed involving three reviewers and guided by an inclusion criteria focused on the evaluation of undergraduate e-learning programmes in the health professions. The initial hit produced 610 articles altogether, and eight articles that met the inclusion criteria were included in the study. Data was then extracted and analysed, and key themes were identified.

Results
Eight Key themes related to LMIC standards emerged from the eight selected articles: curriculum planning, proficiency of educators, learner proficiency and attitude, infrastructure for learning, support and evaluation.

Conclusion
In this review, we synthesised standards that have been used for evaluating undergraduate e-learning programmes in health professions in LMICs. A gap in standards related to clinical teaching and learning in undergraduate e-learning programmes in the health professions was evident from all the included articles. The identification of the eight unique LMIC standards in this review could contribute to guiding towards contextually appropriate quality e-learning programmes in the health professions.
Midgut Volvulus in a Pregnant Patient Presenting With Abdominal Pain
Authors: Scalzo Nicholas , Lin Zilan X. , Yick Frederick , Tewari Virendra 
Published: February 2023

ABSTRACT
Abdominal pain is a common symptom during pregnancy, but bowel obstruction as the cause is a rare phenomenon. Moreover, intestinal volvulus is an even more unusual cause of obstruction during pregnancy and normally involves the sigmoid colon. We report a unique case of midgut volvulus in a pregnant patient entering her third trimester who presented to the hospital with abdominal pain. Our case demonstrates the safety of computed topography in pregnancy while restricting radiation dose and highlights the need to have a high index of suspicion for bowel obstruction when approaching a pregnant patient with abdominal pain.

Biostratigraphy of the Late Campanian–Maastrichtian of the Duwi Basin, Red Sea, Egypt

Published: February 2023

Abstract
During the Late Campanian, sea-level fluctuation occurred in the form of two chert bands and the topmost conglomeratic phosphate beds (CF8a zone). A great transgression event occurred associated with the global warming (CF8b zone) trend indicated by large double-keeled foraminifera as Globotruncana aegyptiaca Nakkady of oligotrophic conditions. Through the event of CF6/CF5 zones, a gradual increase in the relative abundance of Gublerina rajagopalani Govindan and Planoheterohelix planata (Cushman) and other heterohelicids have been shown to tolerate and thrive in a wide range of environmental conditions as in high-stress environments. Sea-level fall at the CF6 zone and the overlying CF5 boundary marked a warming climate for the Middle Maastrichtian Event. In the latest CF4 records, the beginning of the decrease in planktic/benthic ratio, globotruncanids, rugoglobigerinids, and heterohelicids indicating a fall in sea level coincided with the CF4/CF3 and the development of dark grey shales in a regressive regime. The observed low abundance of planktic specimens may be due to the presence of pyrite with black shale interval suggesting low oxygen condition. The latest zones CF3, CF2, and CF1 are generally characterized by heterohelicids blooms specially Planoheterohelix globulosa (Ehrenberg), and a gradual decrease in diversity associated with the warming phase before the K/Pg boundary event, implying high biotic stress to even absent of Guembelitria cretacea species through CF3–CF1 zones. Pseudotextularia elegans (Rzehak) occurs in the zones CF4 and CF2 warming of phases 1 and 2 of Deccan Trap Volcanic. The absence of P. elegans (Rzehak) in the zone (CF3) is postulated due to a tectonic cause (maximum cooling of Deccan Trap Volcanic) whereas its absence in the zone (CF1) was due to regression of phase 2.
Ash melting behavior and mechanism of high-calcium bituminous coal in the process of blast furnace pulverized coal injection
Authors: Chai Yifan , Hu Wenxian , Luo Guoping , Gao Xing , Wang Junjie , Liu Jinzhou 
Published: February 2023

Abstract
High-calcium bituminous coal has the advantages on combustibility, but its ash melting point is low, and it is easy to slag in blast furnace injection process. In order to explore the ash melting slag formation mechanism of high-calcium bituminous coal, the mineral evolution of ash in the combustion process of high-calcium bituminous coal and the influence of ash components on the liquid formation in the melting process were studied. The results showed that the melting behavior of ash gradually occurs with the change in the morphology, and the main mineral transformation is carried out around different deposition forms of Ca and Si. The liquid phase formation of ash at high temperature is the essential reason of its melting behavior. The higher the content of CaO, the higher the starting temperature of the liquid phase formation. The higher the content of SiO2, the lower the starting temperature of the liquid phase formation, and the more the liquid phases generated at a given temperature. Increasing the content of Al2O3 can expand the temperature range of reducing the formation of ash liquid phase to 1,473–1,673 K. When the temperature is above 1,573 K, Fe2O3 can promote ash liquid phase formation.
Comprehension of English articles by Korean learners of L2 English and L3 Spanish
Authors: Park Minjung , García Mayo María del Pilar 
Published: February 2023

Abstract
This study aimed to compare the comprehension of second language (L2) English articles by native speakers of Korean, an article-less language, and by Korean learners of English as an L2 and Spanish as a third language (L3). The participants were 22 adult learners with advanced overall proficiency in L2 English and L3 Spanish. They completed two tasks, an online self-paced reading task and an offline acceptability rating task. The findings showed that both the trilingual and the bilingual groups relied on definiteness in distinguishing English articles as native speakers do. The findings related to the trilingual group were predicted by the morphological congruency hypothesis, but those related to the bilingual group were against the predictions of the fluctuation hypothesis. A comparison between the two non-native groups showed that the trilingual group had a higher sensitivity to distinguish English articles than the bilingual group, which provides evidence for positive backward transfer from the L3 to the L2 in article comprehension by learners of English whose L1 is article-less, such as Korean.
Das werden-Passiv in Schulbüchern der Chemie
Authors: Olthoff Sarah , Romstadt Jonas 
Published: February 2023

Abstract
The competent use of the specific language of school subjects is fundamental for successful learning and teaching in school. For a language-sensitive design of lessons and empirical foundation of didactic and methodical concepts, knowledge of how students read a text is needed as well as evidence-based knowledge of formal and functional aspects of subject-specific language.
A corpus analysis confirms that the passive is a prototypical construction in chemistry textbooks. Thus the competent handling of those sentences is a relevant aspect of subject-specific language competence. The verbs used in the passive sentences in books included in the corpus are predominantly morphologically complex, and can be indicated as chemistry-specific lexis, e. g. related to the sub-microscopic level. Furthermore, they are commonly used in conjunction with abstract agents. On the other hand, these verbs are also encountered to students in everyday (i. e. non-subject-specific) contexts but in these contexts they diverge semantically and are commonly used in conjunction with a human agent. Therefore, the function of the passive sentences differs: While passive sentences with a human agent allow an expression of anonymised actions, the passive sentences with abstract agents enable the verbalisation of abstract processes. The distribution of those functional distinction differs between school subjects and contexts. Abstract agents in passive sentences can support the maintenance of pre-instructional concepts of students, especially if the verbs are not obviously specific for the context of chemistry. Therefore, a specific language-education for school subjects is needed which includes the analysis of formal and functional aspects. The results of the corpus analysis can be used for context-based scaffolding in language-sensitive chemistry lessons.
