Microsphere coupled off-core fiber sensor for ultrasound sensing
Authors: Tatel Gerard , Bao Xiaoyi
Published: November 2022

A compact fiber ultrasound-sensing device comprised of a Barium Titanate (BaTiO3) microsphere coupled to an open cavity off-core Fabry-Perot (FP) fiber sensor fabricated through lateral offset splicing single mode fiber (SMF-28) is proposed and demonstrated. The multiple passes of the FPI enabled by the high refractive index microsphere brought a 40dB enhancement of finesse. The broadband ultrasound sensing over 0.1- 45 MHz is achieved by selecting whispering gallery modes (WGMs) via varying microsphere position. The scattering and internal reflection of light in the microsphere is enabled by multibeam interference, leading to an increase in passages and WGMs at specific resonant wavelengths, and hence the high contrast and quality factor of the transmission spectrum are obtained for broadband ultrasound detection at high sensitivity. The optimized lateral offset is governed by the diameter of the microsphere to maximize the frequency response of the acoustic wave of a piezoelectric transducer centered at 3.7 MHz.

Phase retrieval of programmable photonic integrated circuits based on an on-chip fractional-delay reference path
Authors: Xu Xingyuan , Ren Guanghui , Dubey Aditya , Feleppa Tim , Liu Xumeng , Boes Andreas , Mitchell Arnan , Lowery Arthur J.
Published: November 2022

Programmable photonic integrated circuits (PICs), offering diverse signal processing functions within a single chip, are promising solutions for applications ranging from optical communications to artificial intelligence. While the scale and complexity of programmable PICs are increasing, their characterization, and thus calibration, becomes increasingly challenging. Here we demonstrate a phase retrieval method for programmable PICs using an on-chip fractional-delay reference path. The impulse response of the chip can be uniquely and precisely identified from only the insertion loss using a standard complex Fourier transform. We demonstrate our approach experimentally with a four-tap finite-impulse-response chip. The results match well with expectations and verify our approach as effective for individually determining the taps’ weights without the need for additional ports or photodiodes.

Published: November 2022

In 2014 the Kingdom of Lesotho, in conjunction with Partners In Health, launched a National Health Reform with three components: 1) improved supply-side inputs based on disease burden in the catchment area of each of 70 public primary care clinics, 2) decentralization of health managerial capacity to the district level, and 3) demand-side interventions including paid village health workers. We assessed changes in the quarterly average of quality metrics from pre-National Health Reform in 2013 to 2017, which included number of women attending their first antenatal care visit, number of post-natal care visits attended, number of children fully immunized at one year of age, number of HIV tests performed, number of HIV infection cases diagnosed, and the availability of essential health commodities. The number of health centers adequately equipped to provide a facility-based delivery increased from 3% to 95% with an associated increase in facility-based deliveries from 2% to 33%. The number of women attending their first antenatal and postnatal care visits rose from 1,877 to 2,729, and 1,908 to 2,241, respectively. The number of children fully immunized at one year of life increased from 191 to 294. The number of HIV tests performed increased from 5,163 to 12,210, with the proportion of patients living with HIV lost to follow-up falling from 27% to 22%. By the end of the observation period, the availability of essential health commodities increased to 90% or above. Four years after implementation of the National Health Reform, we observed increases in antenatal and post-natal care, and facility-based deliveries, as well as child immunization, and HIV testing and retention in care. Improved access to and utilization of primary care services are important steps toward improving health outcomes, but additional longitudinal follow-up of the reform districts will be needed.
Cooperation dynamics in dynamical networks with history-based decisions
Authors: Miles Adam Lee , Cavaliere Matteo
Published: November 2022

In many aspects of life on earth, individuals may engage in cooperation with others to contribute towards a goal they may share, which can also ensure self-preservation. In evolutionary game theory, the act of cooperation can be considered as an altruistic act of an individual producing some form of benefit or commodity that can be utilised by others they are associated with, which comes at some personal cost. Under certain conditions, individuals make use of information that they are able to perceive within a group in order to aid with their choices for who they should associate themselves within these cooperative scenarios. However, cooperative individuals can be taken advantage of by opportunistic defectors, which can cause significant disruption to the population. We study a model where the decision to establish interactions with potential partners is based on the opportune integration of the individual’s private ability to perceive the intentions of others (private information) and the observation of the population, information that is available to every individual (public information). When public information is restricted to a potential partners current connection count, the population becomes highly cooperative but rather unstable with frequent invasions of cheaters and recoveries of cooperation. However, when public information considers the previous decisions of the individuals (accepted / rejected connections) the population is slightly less cooperative but more stable. Generally, we find that allowing the observation of previous decisions, as part of the available public information, can often lead to more stable but fragmented and less prosperous networks. Our results highlight that the ability to observe previous individual decisions, balanced by individuals personal information, represents an important aspect of the interplay between individual decision-making and the resilience of cooperation in structured populations.
Psychosocial family-level mediators in the intergenerational transmission of trauma: Protocol for a systematic review and meta-analysis
Authors: Mew Emma J. , Nyhan Kate , Bonumwezi Jessica L. , Blas Vanessa , Gorman Hannah , Hennein Rachel , Quach Kevin , Shabanova Veronika , Hawley Nicola L. , Lowe Sarah R.
Published: November 2022

Introduction

Family-level psychosocial factors appear to play a critical role in mediating the intergenerational transmission of trauma; however, no review article has quantitatively synthesized causal mechanisms across a diversity of trauma types. This study aims to systematically consolidate the epidemiological research on family-level psychosocial mediators and moderators to ultimately produce causal diagram(s) of the intergenerational transmission of trauma.

Methods

We will identify epidemiological peer-reviewed publications, dissertations, and conference abstracts that measure the impact of at least one psychosocial family-level factor mediating or moderating the relationship between parental trauma exposure and a child mental health outcome. English, French, Kinyarwanda, and Spanish articles will be eligible. We will search MEDLINE, PsycINFO, PTSDpubs, Scopus, and ProQuest Dissertations and Theses and will conduct forward citation chaining of included documents. Two reviewers will perform screening independently. We will extract reported mediators, moderators, and relevant study characteristics for included studies. Findings will be presented using narrative syntheses, descriptive analyses, mediation meta-analyses, moderating meta-analyses, and causal diagram(s), where possible. We will perform a risk of bias assessment and will assess for publication bias.

Discussion

The development of evidence-based causal diagram(s) would provide more detailed understanding of the paths by which the psychological impacts of trauma can be transmitted intergenerationally at the family-level. This review could provide evidence to better support interventions that interrupt the cycle of intergenerational trauma.

Training programs in preclinical studies. The example of pulmonary hypertension. Systematic review and meta-analysis
Authors: Jasińska-Stroschein Magdalena
Published: November 2022

Background

Exercise and cardiopulmonary exercise testing are essential in the evaluation of physiological, biochemical, and molecular responses in the experimental studies on chronic diseases such as diabetes, heart failure and hypertension. The exercise tolerance and seem to be a valuable contribution to the experiments that are performed in animal models of pulmonary hypertension (PH), as well. The current survey uses detailed quantitative analyses to assess the advantages of exercise training programs performed in preclinical studies based on outcomes such as exercise capacity, cardiopulmonary hemodynamics, and mortality.

Methods

Articles were identified through search engines in the online electronic databases Pubmed/Medline, Web of Science following the PRISMA Protocol. Studies conducted between 1991 and 2022 without language restrictions were included in this study. Heterogeneity was assessed using the Cochrane Q-test and I2 test statistics. Subgroup analysis was employed with evidence of heterogeneity. Quality assessment was carried out using SYRCLE’s risk of bias tool for animal studies. Publication bias across studies was determined using the funnel plot and Egger’s regression test statistic.

Results

The available protocols typically included treadmill running, swimming, and voluntary wheel running with a different series of intensities, times and durations; these were also used in studies examining the efficacy of chronic training programs. In 66 interventions, PH induction reduced exercise endurance by half compared to healthy subjects, while exposure to tested medical agents normalized exercise capacity. The other 58 interventions demonstrated the advantages of various exercise training programs for PH. Induction of PH reduced exercise endurance by half compared to healthy subjects (R = 0.52; 0.48 − 0.55 95%CI; P<0.0001; I2 = 98.9%), while the exposure to tested medical agents normalized exercise capacity (R = 1.75; 1.61 − 1.91 95%CI; P<0.0001; I2 = 97.8%).

Conclusion

Despite a wide spectrum of study protocols to measure exercise endurance in animals with PH, there is a significant correlation between worsening of exercise-related parameters and PH development, manifested by alterations in haemodynamic and remodeling parameters. Familiarization with exercise, training program schedule, method used for PH induction, or detailed training parameters such as slope, exercise intensity or individualization, can influence the final outcome. This in turn can impact on the diversity and reproducibility of results being obtained in particular experimental studies.
Variability of autonomic nerve activity in dry eye with decreased tear stability

Published: November 2022

The autonomic nervous system plays a crucial role in the maintenance of homeostasis. Neurogenic inflammation due to decreased stability of tear film may induce changes in autonomic nerve activity, which could be associated with symptom expression.This study aimed to measure biological parameters that represent autonomic nerve activity in dry eye (DE)s caused by tear film dysfunction and investigate their relationship with symptom intensity. This prospective, cross-sectional, comparative study evaluated 34 eyes of 34 participants (mean age: 52.5 ± 13.4 years; range: 20–81 years) without keratoconjunctival damage. Nineteen eyes in the DE group showed DE symptoms and tear break-up time (TBUT) of ≤5 seconds (short TBUT DE); the 15 eyes in the non-DE group showed no DE symptoms. Autonomic nerve activity was measured for 10 minutes—starting and ending 5 minutes before and after instilling ophthalmic solution—and evaluated using the low-frequency component (LF) to the high-frequency component (HF) ratio of heart rate variability (autonomic balance). The pre-ophthalmic solution administration LF/HF ratio was not significantly different (P = 0.59) between the two groups, however, the standard deviation of the LF/HF ratio (LF/HF-SD) tended to be higher in the DE group than that in the non-DE group (P = 0.086). The DE symptom intensity was significantly related to LF/HF-SD (P = 0.005), which significantly decreased after ophthalmic solution administration in the DE group (P = 0.04). The large fluctuations in autonomic balance may be key for the understanding of the mechanism underlying DE symptoms.

After intervention of the program, environmental severity (F = 17.96, p < .001), response efficacy (F = 15.69, p < .001), and total environmental perception (F = 7.80, p = .008) were higher in the experimental group than in the control group. There were no significant differences in feasibility, accessibility, satisfaction, susceptibility, self-efficacy, barrier, personal environmental behavior, and community environmental behavior between the two groups.

Conclusion

The internet-based educational program can be the alternative for the face-to-face prenatal class to promote environmental health perceptions during pregnancy in the pandemic situations.
Effect of SARS-CoV-2 digital droplet RT-PCR assay sensitivity on COVID-19 wastewater based epidemiology

We developed and implemented a framework for examining how molecular assay sensitivity for a viral RNA genome target affects its utility for wastewater-based epidemiology. We applied this framework to digital droplet RT-PCR measurements of SARS-CoV-2 and Pepper Mild Mottle Virus genes in wastewater. Measurements were made using 10 replicate wells which allowed for high assay sensitivity, and therefore enabled detection of SARS-CoV-2 RNA even when COVID-19 incidence rates were relatively low (~10−5). We then used a computational downsampling approach to determine how using fewer replicate wells to measure the wastewater concentration reduced assay sensitivity and how the resultant reduction affected the ability to detect SARS-CoV-2 RNA at various COVID-19 incidence rates. When percent of positive droplets was between 0.024% and 0.5% (as was the case for SARS-CoV-2 genes during the Delta surge), measurements obtained with 3 or more wells were similar to those obtained using 10. When percent of positive droplets was less than 0.024% (as was the case prior to the Delta surge), then 6 or more wells were needed to obtain similar results as those obtained using 10 wells. When COVID-19 incidence rate is low (~ 10−5), as it was before the Delta surge and SARS-CoV-2 gene concentrations are <104 cp/g, using 6 wells will yield a detectable concentration 90% of the time. Overall, results support an adaptive approach where assay sensitivity is increased by running 6 or more wells during periods of low SARS-CoV-2 gene concentrations, and 3 or more wells during periods of high SARS-CoV-2 gene concentrations.
Remapping youth activism and citizenship in Chile through the legacy of the Chilean student movement
Authors: Hernandez Santibañez Ivette
Published: November 2022

This article analyses youth activism in Chile through the lens of the Chilean student movement. It examines new forms of grassroots politics and popular democracy that have been at the core of struggles led by the Chilean student movement since the early 2000s. The article reflects on the legacy of this student movement regarding the transformation of the character and meaning of citizenship, politics and democracy within a post-authoritarian democratic society. The relationship between education and citizenship is placed in context, paying special attention to how grievances around education are key to making education a space for the legitimization of new ways of being political. The article discusses the implications, in the context of the 2019–20 Chilean protests, of the new forms of politics and the political that were part of the legacy of the Chilean student movement.
Authoritarian cosmopolitan citizenship in the new nation of South Sudan: Insights from a secondary school textbook analysis
Authors: Skårås Merethe , Bentrovato Denise
Published: November 2022

Citizenship education (CE) is increasingly implemented in national curricula, often as an independent subject. In this article we examine the first official citizenship textbooks for South Sudan secondary education since independence in 2011. We analyse four textbooks, observing a multifaceted and at times contradictory understanding of the kind of citizens the new textbooks promote. Our findings point to a case of ‘authoritarian cosmopolitan citizenship’, coined here as a concept envisioning a loyal cosmopolitan citizen who is uncritical of both government and international actors and the activities, norms and values they promote.

Reflections on a year of kink
Authors: Hart Kylo-Patrick R.
Published: November 2022

Until relatively recently, the topic of kink has not typically been encountered in either polite company or mainstream popular culture. In response to this reality, this editorial highlights ways by which one scholar/photographer intentionally endeavoured to highlight, demystify and destigmatize kinky activities, relationships and representations over the course of a twelve-month period.
Representing, repressing and pushing back: Queer and trans (in)visibilities in media, law and culture
Authors: Kreitler Melanie , Borchert Laura
Published: November 2022

The increasing focus on non-normative gender identities and sexual orientations in cultural discourses creates a paradox for LGBTQIAP* communities. On the one hand, increased visibility paves the way for greater tolerance in the general public; on the other hand, it may also suggest the logical fallacy that on-screen representations mirror off-screen realities. This article argues that the hyper-visibility of queerness in media maintains and legitimizes existing, cis-heteronormative sociocultural orders that are reflected in legal developments. Further, the (popular) cultural discourse about queerness adds to its continuing normativization. The ‘mainstreamification’ of queerness risks cementing legal inequalities for LGBTQIAP* persons, leaving queers vulnerable to discrimination while popular discourse is able to imagine an emancipated queer subject on-screen.
God vs. gay: Queer counter-storytelling and Christianity in films about conversion therapy
Authors: Coon David R.
Published: November 2022

This article compares dramatizations of ex-gay conversion therapy in the films But I’m a Cheerleader (1999), Save Me (2007), The Miseducation of Cameron Post (2018) and Boy Erased (2018) to demonstrate how the films refute the harmful myths circulated by ex-gay ministries and thereby combat the anti-gay agendas that such ministries support. The films all emphasize the liberation of their queer protagonists, but they differ in their treatment of Christian antagonists, with depictions ranging from mocking to hostile to sympathetic. I argue that while all four films offer empowering representations of lesbians and gay men surviving conversion therapy, only Save Me employs a rhetorical strategy that seeks to reconcile the perceived conflict between queerness and Christianity.
Imagologia e Mobilidade - Movidas e Migrações Figuradas
Authors: Simões Maria João
Published: November 2022

Os objetivos desta obra decorrem de um conjunto de questões importantes no mundo atual: Será pertinente continuar a colocar questões relativas à identidade e à pertença identitária coletiva num mundo globalizado? Será útil a utilização de uma perspetiva imagológica para refletir sobre as nossas próprias representações culturais e as representações de outras culturas? Será preferível falar em transnacionalismo literário ou em literatura migrante? Fruto de reflexões e debates realizados sobre estas questões pelos investigadores do projeto “Literatura, Imagologia e Transnacionalismo”, os ensaios que aqui se reúnem examinam a ficcionalização de temas decorrentes quer de sentimentos de desenraizamento ou de desinserção cultural, quer do peso psíquico das mobilidades forçadas, em diversas obras literárias. Assim, este volume tem uma dimensão de análise literária, mas, para além disso, alarga-se também a uma dimensão cultural, uma vez que os diversos textos investigam como são construídas e expostas personagens que foram ou são agentes de mobilidade (com a suas dependências estruturais e contextuais), mas também os reflexos e as sequelas dessa mobilidade nas gerações seguintes, também elas mergulhadas em múltiplos choques culturais.

Authors: Oguntuyo Kasopefoluwa Y. , Donnangelo Lauren L. , Zhu Guangjing , Ward Stephen , Bhattacharaya Abhik
Published: November 2022

Mucosal Schwann cell hamartomas (MSCHs) are benign neural lesions that are not associated with inherited syndromes and are primarily found in the distal colon. We report the first case of an MSCH in the duodenum. This case highlights the expansive nature of MSCHs and discusses the implications of this finding in the duodenum and in the context of a hematologic malignancy.

Formative assessment in second language learning: a systematic review and an annotated bibliography
Authors: Vassiliou Skevi , Papadima-Sophocleous Salomi , Giannikas Christina Nicole
Published: November 2022

Throughout its whole history, most research conducted in language assessment refers to testing. It is only since 2000 that language formative assessment started being recorded in research publications. This book tells the story of language formative assessment in two ways, the one complementing the other: in the forms of a systematic review and a descriptive and evaluative annotated bibliography, from the very first published work on the subject in 2000 to 2020. While the systematic review gives the story of language formative assessment in a chronological order and gives an overview of different aspects, the annotated bibliography gives more details for research work published. Τhe main purposes of the book are to (1) give a substantial background in the area, (2) describe how this topic has been approached, (3) contribute to the development of critical thinking, (4) help in establishing the relevance and quality of the annotated material, and (5) facilitate language formative researchers as well as practitioners to form an overview of the research in the area during the specific period under study. The book may be of interest to language practitioners, researchers, teacher trainers, and policy makers. The authors hope that the present publication will be viewed as a valuable contribution to the history of language formative assessment.

Situovaná (auto)mobilita ve venkovském mikroregionu
Authors: Šalanda Bohuslav
Published: November 2022

The paper examines the assumptions and conditions of (auto)mobility in a rural microregion in eastern Bohemia, specifically in the localities of municipalities of Široký Důl and Trstěnice. In this manner situated mobility becomes an important part of the research. Using this background, the relationships of transport users to mobility, their experiences, ideas and opinions are studied. Knowledge included in the study was obtained through the author’s own field research. The overall picture of historical development of motoring would not be complete without rural environment forming specific conditions for this area of practical human activity.
