Abstract
Background
The coronavirus disease 2019 (COVID-19) pandemic paralyzes the education sector. To minimize the interruption of teaching and learning, most universities in Malaysia shifted to virtual mode during this unprecedented period of the pandemic. With an ever-increasing number of Malaysians fully vaccinated against COVID-19, the education system is expected to switch back to face-to-face mode this year. It is crucial to assess the knowledge, attitudes, and practices (KAP) of COVID-19 among emergency remote learning undergraduates before reverting to physical teaching and learning. Hence, a study was conducted with this aim in mind.

Methods
A total of 299 Malaysian undergraduates were recruited through a snowball sampling approach. The online questionnaire encompassed three main segments: informed consent, sociodemographic information, and KAP questions on COVID-19.

Results
The mean scores for knowledge, attitude, and practice were 4.05/6, 11.14/12, and 5.07/7, respectively. The results of the present study showed that year 1 respondents had significantly higher levels (p < 0.05) of KAP scores than year 4 respondents. In addition, the attitude score of science majors respondents was significantly greater (p < 0.05) than those of nonscience majors. The KAP scores showed no significant difference among groups with different sexes, ethnicities, and COVID-19 histories. Partial correlation analysis revealed that the overall knowledge score was positively correlated with attitude (r = 0.193, p = 0.001) and practice (r = 0.343, p < 0.001) scores whereas the total attitude score was positively correlated with the total practice score (r = 0.149, p = 0.010).

Conclusion
Our current results suggest that COVID-19 workshops, seminars, or training programs for year 4 students could be conducted to enhance their KAP levels.

Abstract

Objectives:
This study aimed to assess the feasibility and acceptability of implementing non-pharmaceutical interventions (NPIs) reserved for influenza pandemics (voluntary home quarantine, use of face masks by ill persons, childcare facility closures, school closures, and social distancing at schools, workplaces, and mass gatherings).

Methods:
Public health officials in all 50 states (including Washington, DC) and 8 territories, and a random sample of 822 local health departments (LHDs), were surveyed in 2019.

Results:
The response rates for the states/ territories and LHDs were 75% (44/ 59) and 25% (206/ 822), respectively. Most of the state/ territorial respondents stated that the feasibility and acceptability of implementing NPIs were high, except for K-12 school closures lasting up to 6 weeks or 6 months. The LHD respondents also indicated that feasibility and acceptability were lowest for prolonged school closures. Compared to LHD respondents in suburban or urban areas, those in rural areas expressed lower feasibility and acceptability. Barriers to implementing NPIs included financial impact, compliance and difficulty in enforcement, perceived level of disease threat, and concerns regarding political implications.

Conclusion:
Proactive strategies to systematically address perceived barriers and promote disease prevention ahead of a new pandemic are needed to increase receptivity and consistent adoption of NPIs and other evidence-based countermeasures.
On Dialogical Writing, Self-forming, and Salon Culture: Rahel Varnhagen, Henriette Herz, and Fanny Lewald
Authors: Wagner Ulrike 
Published: August 2022

AbstractSalons evoke high-flown associations; we picture elegant people gathering in glamorous settings for cultivated conversations about the arts, literature, and politics. The so-called salons hosted around 1800 in Berlin by bourgeois Jewish women are tied to promises of emancipation and religious toleration. Scholars have either hailed the empowering functions of these convivial gatherings or debunked their enlightened promises as myths. Drawing on the latest research on conviviality in the social sciences, on Friedrich Schleiermacher's theory of sociability, and on writings by and about Rahel Varnhagen, Henriette Herz and Fanny Lewald, this essay approaches the topic of the salon from a different angle. I argue that these women's social endeavours were not tied to specific ends that we can either admiringly endorse or expose as failures from today's perspective. The notions of the female self, of writing, and the conceptions of literature and philosophy emerging from these convivial constellations are inherently dialogical and shifting. Conversations may sometimes break open hierarchies, but they may also foster conflict and no improvement. The value of these encounters, I suggest, lies in the effort made rather than a classifiable outcome.
Central-line–associated bloodstream infections in a pediatric oncology and hematology hospital at home program
Authors: Raimbault Sylvain C. , Domenech Carine , Fuhrmann Christine , Bertrand Amandine 
Published: August 2022

AbstractObjective:Central-line–associated bloodstream infections (CLABSIs) are associated with significant morbidity among pediatric oncology-hematology patients, and risk factors remain largely unknown in the setting of hospital at home (HAH). Children in HAH receive intensive treatment (eg, chemotherapy and parenteral nutrition), with frequent central-line handling; thus, they may be at higher risk for CLABSI.Methods:We conducted a monocentric retrospective study of patients with a central line included in our HAH program from January 1 to December 31, 2016. HAH patient characteristics for children developing CLABSIs were compared to those who did not, based on blood cultures positive for infection and clinical data of all patients included.Results:Overall, 492 HAH stays were analyzed, with 144 patients. The overall CLABSI rate in these patients was 2.6 per 1,000 central-line days. Children who developed CLABSIs were younger (median age, 2.5 vs 8.8 years; P < .001), suffered more from hematological pathologies (malignant or nonmalignant, 75% vs 52%; P = .02), and had more frequently undergone hematopoietic stem-cell transplantation (30.8% vs 6.5%; P = .01). In addition, these patients often had a tunneled externalized catheter as the central line and were more frequently given parenteral nutrition at home (46% vs 8%; P < .001).Conclusions:CLABSI rates for children in HAH were more similar to those of inpatients than to rates previously reported for ambulatory patients. The factors associated with infection identified herein should be further validated in multicentric studies and considered to improve HAH practices, parallel to prevention measures used in the inpatient setting.

Abstract
The role of dietary factors in osteoporotic fractures (OFs) in women is not fully elucidated. We investigated the associations between incidence of OF and dietary calcium, magnesium and soy isoflavone intake in a longitudinal study of 48 584 postmenopausal women. Multivariable Cox regression was applied to derive hazard ratios (HRs) and 95 % confidence intervals (CIs) to evaluate associations between dietary intake, based on the averages of two assessments that took place with a median interval of 2⋅4 years, and fracture risk. The average age of study participants is 61⋅4 years (range 43⋅3–76⋅7 years) at study entry. During a median follow-up of 10⋅1 years, 4⋅3 % participants experienced OF. Compared with daily calcium intake ≤400 mg/d, higher calcium intake (>400 mg/d) was significantly associated with about a 40–50 % reduction of OF risk among women with a calcium/magnesium (Ca/Mg) intake ratio ≥1⋅7. Among women with prior fracture history, high soy isoflavone intake was associated with reduced OF risk; the HR was 0⋅72 (95 % CI 0⋅55, 0⋅93) for the highest (>42⋅0 mg/d) v. lowest (<18⋅7 mg/d) quartile intake. This inverse association was more evident among recently menopausal women (<10 years). No significant association between magnesium intake and OF risk was observed. Our findings provide novel information suggesting that the association of OF risk with dietary calcium intake was modified by Ca/Mg ratio, and soy isoflavone intake was modified by history of fractures and time since menopause. Our findings, if confirmed, can help to guide further dietary intervention strategies for OF prevention.
Working-Class Leaders and Their Political Work Between Civil-Societal Engagement and Class Conflicts: The Case of August Bebel – A Comment to John D. French
Authors: Schmidt Jürgen 
Published: August 2022

AbstractJohn D. French's stimulating article, which explores the scope for comparing working-class leaders across time and space, is considered in this contribution by reference to my biography of August Bebel and with a particular focus on the following topics: a) historical actors as shaped by their own particular time and place; b) the importance of personal relationships and networks in making people who they are; c) the importance of psychological elements and the risk in interpreting them in retrospect – recovering them depends upon the sources available; d) how charisma reflects an interdependence between attribution and individual qualities; e) the importance of political milieux for the flourishing of individual working-class leaders; and f) the relationship between political work to both civil society and existing class relations. Using these approaches allows us to write cross-border and cross-temporal “embodied social biographies”, as suggested by French.
‘To Satisfy My Savage Appetite’: Slavery, Belief, and Sexual Violence on the Mina (Gold) Coast, 1471–1571
Authors: Konadu Kwasi 
Published: August 2022

AbstractScholars of women and girls in African history, focusing on gender and power within religious or colonial (slavery) contexts, have drawn our attention to sexual violence against girls and women. Despite what historians of slavery and imperial violence have noted about their vulnerability and survival strategies in ‘colonial’ and ‘postcolonial’ contexts, questions remain about sexual predation and slavery in earlier periods. In the Mina (Gold) Coast, there is little known about the lived experiences of enslaved and ‘freed’ girls and women in the sixteenth century, and this is especially true for females held captive or in proximity to Portuguese slaving and gold trading bases of operation. Although only three inquisitional trials exist, sources which provide rare African female voices in the Portuguese colonial and evangelical world, their unprecedented baseline evidence for those under Portuguese slaving and religious authority tell us much about sexual violence, slavery, and religious orthodoxy.

AbstractObjectiveThis study aimed to assess the effectiveness of an ENT simulation course for equipping foundation doctors with core ENT skills in preparation for an ENT senior house officer post.MethodA total of 41 foundation doctors in the East of England participated in our two-part simulation course. Pre- and post-course surveys, consisting of Likert scales and a Dundee Ready Educational Environment Measure, were sent to assess confidence in core ENT skills and acceptability of course format.ResultsPost-simulation, confidence improved in all core ENT skills taught (p < 0.001), along with confidence and preparedness to work as an ENT senior house officer (p < 0.001). Overall course median Dundee Ready Educational Environment Measure score was 48, and 100 per cent of participants would recommend this course to colleagues.ConclusionSimulation improves foundation doctors’ confidence in core ENT skills and increases preparedness for working as an ENT senior house officer. Guidance on core ENT skills requirements should be made available to improve uniformity amongst ENT simulation courses.

AbstractFor species without parental care, such as sea turtles, nest site selection is particularly important for embryo development, hatchling survival and, ultimately, reproductive success. We conducted an 8-year (2012–2019) capture–mark–recapture study of the re-nesting behaviour of loggerhead turtles Caretta caretta to identify both inter- and intra-beach patterns of nest site selection. Our study site, Maio Island in the archipelago of Cabo Verde, hosts one of the largest loggerhead turtle nesting colonies globally. Of 1,060 females analysed, 77% laid repeated clutches within 15 km of their previous nesting sites both between and within nesting seasons. This site fidelity was particularly high (64–71%) for turtles nesting on the east coast of Maio Island. In two areas of the island (north-west and south-east) individual nesting zone consistency was extremely low (10–25%). In all cases extra-zone re-nesting events mainly occurred on the east coast. We also found that females avoided re-nesting near the shoreline, which is particularly relevant in the context of rising sea levels. Overall, loggerhead turtles nesting in Maio Island are philopatric but are using a bet-edging strategy to distribute nests amongst several beaches, choosing the safest area within each beach to maximize their reproductive success. This study highlights the priority sites for protection on Maio Island and could help to optimize capture–mark–recapture programmes. The data reveal the potential for adaptive responses to projected sea level rises.
Holding International Organizations Accountable: Toward a Right to Justification in Global Governance?
Authors: Reinold Theresa 
Published: August 2022

AbstractThis essay suggests that the accountability trends explored by Stian Øby Johansen and Gisela Hirschmann in their respective monographs should be viewed as indicating the emergence of a right to justification in global governance. Both Johansen and Hirschmann seek to advance the interdisciplinary conversation about the accountability of international organizations—Johansen by developing a normative framework assessing the quality of IO accountability mechanisms, and Hirschmann by seeking to identify the variables that shape the evolution of what she calls pluralist accountability. Building upon their analyses, I put forward a set of hypotheses about the procedural and substantive dimensions of the right to justification as well as the conditions for its consolidation in global governance.
A Professional Development Course for Political Science Undergraduates
Authors: Bram Curtis 
Published: August 2022

ABSTRACTThis article describes a course designed to help political science majors formulate career goals, apply for internships and full-time positions, and eventually succeed on the job. Students benefit from exposure to guest speakers representing a range of careers and from collaborations with other campus institutions (e.g., the career center and graduate programs). Additionally, students produce job-market materials that highlight how their education has prepared them for life and work. Offering a similar professional-development course can help departments to increase enrollments and majors by increasing students’ confidence in the career prospects associated with their major.
Children's likelihood to perform adult-like in word association test: Effects of bilingualism and distributional properties of word relationships
Authors: Lam Boji P. W. , Sheng Li , Zhang Xian 
Published: August 2022

AbstractLittle is known about the effects of bilingualism and distributional properties of word relationships on children's development of semantic convergence, operationalized as children's ability to produce word associates that mirror adults’ responses in a word association task. Forty-five Mandarin–English bilingual, 32 Spanish–English bilingual, and 28 English-speaking monolingual children, aged 4 to 7, produced three associates to each of 15 single-word cues in English. Children's productions were compared against adult responses to the same cues in the “Small World of Words” Norm. Three scoring methods comparing similarities of children's responses to adults’ showed consistent bilingual disadvantages in producing adult-like responses. Follow-up analyses targeted the three most predominant responses adults produced for each cue and addressed factors predicting children's likelihood to produce these responses. Results showed additional effects of cue-associate relationships measured by co-occurrence and semantic relatedness. The findings highlight the multi-faceted nature of knowledge development of word relationship and semantic convergence.

AbstractWe present a self-biased three-stage GaN-based monolithic microwave integrated circuit low-noise amplifier (LNA) operating between 26 and 29 GHz for 5G mobile communications. The self-biasing circuit, common-source topology with inductive source feedback, and RLC negative feedback loops between gate and drain of the third transistor were implemented to achieve low noise, good port match, high stability, high gain, and compact size. Measurement results show that the LNA has a high and flat gain of 30.5 ± 0.4 dB with noise figure (NF) of 1.65–1.8 dB across the band. The three-stage topology also achieves high linearity, providing the 1 dB compression point output power (P1dB) of 21 dBm in the band. To our knowledge, this combination of NF, gain, and linearity performance represents the state of art of self-biased LNA in this frequency band.

AbstractThe in vitro modeling of human brain connectomes is key to exploring the structure-function relationship of the central nervous system. Elucidating this intricate relationship will allow better studying of the pathological mechanisms of neurodegeneration and hence result in improved drug screenings for complex neurological disorders, such as Alzheimer’s and Parkinson diseases. However, currently used in vitro modeling technologies lack the potential to mimic physiologically relevant neural structures. Herein, we present an innovative microfluidic design that overcomes one of the current limitations of in vitro brain models: their inability to recapitulate the heterogeneity of brain regions in terms of cellular density and number. This device allows the controlled and uniform deposition of any cellular population within unique plating chambers of variable size and shape. Through the fine tuning of the hydrodynamic resistance and cell deposition rate, the number of neurons seeded in each plating chamber can be tailored from a thousand up to a million. By applying our design to so-called neurofluidic devices, we offer novel neuro-engineered microfluidic platforms that can be strategically used as organ-on-a-chip platforms for neuroscience research. These advances provide essential enhancements to in vitro platforms in the quest to provide structural architectures that support models for investigating human neurodegenerative diseases.

Published: August 2022

AbstractObjectivesTo detect the serum level of thyroid hormones, vitamin D and vitamin D receptors (VDR) polymorphism in keratoconus (KC) patients and to identify the association between vitamin D deficiency and thyroid dysfunction in KC.MethodsThis cross sectional study included 177 KC patients with no thyroid disorders compared to 85 healthy controls with normal corneal tomography. Measurements of thyroid stimulating hormone (TSH), free triiodothyronine (FT3), free tetraiodothyronine (FT4) and serum 25-OH vitamin D were done using Enzyme linked immusoassay (ELISA test). VDR polymorphisms were tested including [Taq I (rs731236), Apa I (rs7975232) and Bsm I (rs1544410)] using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).ResultsAn increase in frequency of thyroid disorders (P = 0.04), decrease in serum 25(OH) vitamin D level (P < 0.001), Taq 1 and tt genotype (P < 0.001) were significantly distributed in KC patients. A significantly higher serum 25(OH) vitamin D level was reported in TT genotype, while insufficient level was more common in Tt genotype (P < 0.001). A deficient serum 25(OH) vitamin D level was predominant in tt genotype (P < 0.001). A 95% confidence interval was in TSH (1.603, 2.946), FT4 (24.145, 77.06), hypothyroidism (1.062, 67.63), insufficient (2.936, 11.643) and deficient vitamin D (5.283, 28.704) and all were significant risk factors for KC with (P < 0.05).ConclusionsBoth thyroid disorders and low vitamin D are potential factors for KC development. Studying VDR at the molecular level provides interesting avenues for future research toward the identification of new KC cases.
Global analysis and prediction of fluoride in groundwater
Authors: Podgorski Joel , Berg Michael 
Published: August 2022

AbstractThe health of millions of people worldwide is negatively impacted by chronic exposure to elevated concentrations of geogenic fluoride in groundwater. Due to health effects including dental mottling and skeletal fluorosis, the World Health Organization maintains a maximum guideline of 1.5 mg/L in drinking water. As groundwater quality is not regularly tested in many areas, it is often unknown if the water in a given well or spring contains harmful levels of fluoride. Here we present a state-of-the-art global fluoride hazard map based on machine learning and over 400,000 fluoride measurements (10% of which >1.5 mg/L), which is then used to estimate the human population at risk. Hotspots indicated by the groundwater fluoride hazard map include parts of central Australia, western North America, eastern Brazil and many areas of Africa and Asia. Of the approximately 180 million people potentially affected worldwide, most reside in Asia (51–59% of total) and Africa (37–46% of total), with the latter representing 6.5% of the continent’s population. Africa also contains 14 of the top 20 affected countries in terms of population at risk. We also illuminate and discuss the key globally relevant hydrochemical and environmental factors related to fluoride accumulation.
