The Synekism of Catholic Faith and Citizenship in Peninsular Malaysia
Authors: Pillai Shanthini
Published: December 2021

In this paper, I focus on the influence of the Société des Missions étrangères de Paris (MEP) on the performative poetics of Christian faith and citizenship among Malaysian Catholics. Using the central trope of the house, both in its general context of home and dwelling, and its Christian context of the church as a house of worship, I specifically show how cross-border movements, through intersections of individual, material, and cultural mobility stretching across centuries have led to synekistic practices of subject formation in the religious sphere. In this way the paper interjects into discourses on conflict between Christianity and the state and highlights alternative notes of interdependencies and creative synergies.
Terrorist Offenses and Juveniles – a Comparison between Germany and Turkey
Authors: Balo Yusuf Solmaz , Butz Felix
Published: December 2021

Terrorism criminal law and juvenile criminal law are branches of law that modify default criminal law provisions. In terms of their goals, these approaches mostly oppose each other. While the primary purpose of terrorism law is to meet the security needs of society, juvenile criminal law serves the privileged interests of juveniles and their reintegration to that society. With increasing active recruiting of juveniles by terrorist organizations, the question arises of what legal systems are doing in the face of juvenile terrorist offenses. This paper analyses and compares legal responses to terrorist crimes by juveniles in Germany and Turkey. The authors conclude that in Germany juvenile terrorist offenses are granted the benefits of juvenile criminal law to a higher degree than in Turkey. This has various legal and extra-legal reasons; however, in both legal systems reforms seem necessary to react more adequately to this troubling form of juvenile delinquency.
Legitimizing the Shrinking of Democratic Space in Western Liberal Democracies
Authors: Tsoukala Anastassia
Published: December 2021

This paper aims at making a synthesis of the main discursive schemes at work across Western liberal democracies that have sought to legitimize the introduction of liberty-restricting counter-terrorism policies since the September 11th attacks. Redefinition of the nature of threat, of the attackers’ key features and of endangered values has gone along with the conceptual reversal of the definition of democracy and freedom as political value. The normalization of the ensuing illiberal forms of governance arguably suggests that the shrinking of post-war democratic achievement uncovers above all liberal democracy’s inherent political vulnerability.

Biblical Anthroponyms and Toponyms in the Ukrainian Language: Basic Vectors of Research DevelopmentThis article considers the main features of the functioning and development of biblical anthroponyms in the modern Ukrainian language. On the one hand, proper names associated with religion serve to reflect the religious map of the world; on the other – they undergo desacralization and resacralization. This means that their pragmatic potential can expand and they can acquire non-religious semantics.As precedent names, biblical anthroponyms and toponyms reveal their pragmatic potential, first of all, in the belles-lettres style. Despite the conservatism of academic style, biblical anthroponyms function there as well, enriching scientific terminology. In the publicist style, biblical proper names are often used in strong text positions of headings. Most of the analysed units are used as symbols. Semantic and connotative amplitudes of biblical onyms are so wide that they have become the object of word game resulting in polysemy of some units and even their enantiosemy. Biblijne antroponimy i toponimy w języku ukraińskim – główne kierunki rozwojuW artykule analizuje się podstawowe cechy funkcjonowania i rozwoju biblijnych nazw osobowych we współczesnym języku ukraińskim. Nazwy własne związane z religią z jednej strony służą do odzwierciedlenia religijnego obrazu świata, z drugiej strony są poddawane desakralizacji i resakralizacji. Proces ten stwarza możliwość rozszerzenia ich potencjału pragmatycznego i uzyskania przez nie semantyki pozareligijnej.Biblijne antroponimy i toponimy stanowiące precedensowe nazwy własne realizują swój potencjał przede wszystkim w stylu literackim. Pomimo konserwatyzmu charakterystycznego dla stylu naukowego także w nim funkcjonują biblijne antroponimy i toponimy, które wzbogacają terminologię naukową. Biblijne nazwy własne w stylu publicystycznym są często wykorzystywane w wyrazistych tekstowych pozycjach nagłówków. Większość przeanalizowanych jednostek spełnia rolę symbolu. Semantyczne i konotacyjne amplitudy biblijnych onimów są na tyle pojemne, że stały się obiektem gry słownej prowadzącej do wieloznaczności, a nawet enancjosemii niektórych jednostek.
Femoral-Femoral Bypass for Limb Salvage to Correct Common Iliac Occlusion after Lower Extremity Trauma
Authors: Castater Christine , Hazen Ben , Barrett G. Stewart , Davis Carolyn , Butler Caroline , Ramos Christopher , Smith Randi N.
Published: December 2021

Background

Roadway injuries are a leading cause of lower extremity vascular trauma. Treating these injuries involves controlling life-threatening hemorrhage and restoring distal perfusion.

Materials and Methods

We describe a unique presentation of chronic iliac artery occlusion in the setting of blunt trauma requiring extra-anatomic bypass for maximal limb salvage.

Results

A 50-year-old male presented after a pedestrian versus auto accident. He had mangled bilateral lower extremities and was taken emergently for lower extremity amputations. He was found to have chronic left common iliac occlusion and a femoral-femoral bypass was performed to assist with healing his left below-the-knee amputation

Discussion

Lack of adequate perfusion can cause poor outcomes in limb salvage. This case demonstrated that lower extremity trauma can be complicated by chronic vascular disease. Reperfusion and adequate wound healing can be accomplished by using bypass grafting after more traditional reperfusion techniques fail.
Conservative Management of Large Tracheal Perforation due to Traumatic Intubation
Authors: Yu Yasong , Sambol Justin T. , Shakir Huzaifa A.
Published: December 2021

Tracheal perforation is a rare complication of intubation and is associated with high mortality. Here we describe a case of large, full-thickness tracheal perforation from traumatic intubation after an elective procedure. The injury was managed with prolonged intubation that bypassed the site of injury, and the patient was successfully extubated after 11 days. Conservative management of tracheal perforation after traumatic intubation is an option in select patients that avoids need for surgery.
Measurement of Lingual Artery Using Ultrasound Versus Computed Tomography Angiography for Midline Glossectomy in Patients With Obstructive Sleep Apnea
Authors: Zheng Chenhai , Shi Lei , Xing Dengxiang , Qin Jie , Ji Peipei , Li Shuhua , Wu Dahai
Published: December 2021

Objective:

To clarify the differences in assessing the course of the lingual artery between lingual artery computed tomography angiography (CTA) and ultrasound (US).

Methods:

Twenty-six OSA patients were included in this study and accomplished lingual artery CTA and US, respectively. The differences in the depths of the lingual arteries and the distances between the bilateral lingual arteries on 3 measurement levels based on lingual artery CTA and US were compared.

Results:

The depths of the lingual arteries on 3 measurement levels by CTA were deeper than those by US ( P < .01). There was no significant difference in the distances between bilateral lingual arteries on 3 measurement levels between CTA and US ( P > .05).

Conclusions:

The parameters of lingual artery measured by lingual artery US were similar to or smaller than those measured by lingual artery CTA. Like lingual artery CTA, lingual artery US could be used as an effective method to ensure the safety of the operation.
Broad or Narrow Stakeholder Management? A Signaling Theory Perspective
Authors: Fu Limin , Boehe Dirk M. , Orlitzky Marc O.
Published: December 2021

To mitigate risk, should companies signal a broad range of environmental, social, and governance (ESG) initiatives or instead focus on only a few ESG issues? Drawing on signaling theory, we propose that a broad array of ESG initiatives generates not only signal consistency but also accelerating signal costs. Our empirical results support the resultant hypothesis of a curvilinear relationship between ESG scope and equity risk. In addition, this U-shaped curve seems to become steeper when firms face multiple media-reported ESG controversies. Overall, our study qualifies the conventional wisdom that firms can reduce equity risk by attending to a wide variety of stakeholders and highlights the moderating (signal-amplifying) impact of the firm’s media environment.
Questing for Justice on Twitter: Topic Modeling of #StopAsianHate Discourses in the Wake of Atlanta Shooting
Authors: Lee Claire Seungeun , Jang Ahnlee
Published: December 2021

On March 16, 2021, a shooting in Atlanta killed eight people, six were women of Asian descent. This creates a new atmosphere online and offline to discuss hate crimes, racism, and violence against Asian Americans in the United States. The current research utilizes structural topic modeling and text mining to explore how the 2021 Atlanta shooting ignited debates and public discourse on the #StopAsianHate-related conversations on Twitter. The study analyzes the first 7 days of the shooting to explore the temporal patterns and emergent topics of Twitter discourses. Findings show that salient topics and temporal patterns differ from day to day, but topics such as “stand with AAPI community” and “stop racism” are prevalent throughout the 7-day period. This study discusses social media’s role in shaping and reporting public discourses, that is, how digital justice is exercised, and offers social and policy implications. There can be implications for social media’s role in shaping and reporting public discourses on social phenomena with digital justice.
Cyberbullying-Victimization Overlap Among Chinese University Students: Does Network Structure Matter?
Authors: Liu Tzu-Hsuan , Ma Zhihao , Xia Yiwei
Published: December 2021

With widespread internet and social media use among youngsters, cyberbullying has emerged as a novel form of bullying. According to the routine activity and lifestyle theories, cyberbullying and victimization overlap significantly. However, the nature and mechanism of the overlap is not yet adequately understood. This study contributes to extant literature by investigating the role of network structure in cyberbullying-victimization overlap. Participants included 520 residential students from a single department of a Chinese university. This study applied prevalent, bivariate, and social network approach to investigate the overlap. Linear regressions with interactive terms are applied to investigate the moderating effect of network structure. First, the results revealed that the overlap phenomenon is robust against different approaches. Second, the findings demonstrated that indegree significantly moderates the effect of victimization on the perpetration of cyberbullying. Third, for betweenness and closeness, neither direct effect nor moderating effect, is statistically significant. Overall, cyberbullying-victimization overlaps among surveyed Chinese university students and social network may moderate the relationship between cyberbullying and victimization.
India’s Labour Agreements with the Gulf Cooperation Council Countries: An Assessment
Authors: Hameed Sameena
Published: December 2021

Despite the Indian government's proactive initiatives and reforms in the labour laws in the host countries, the welfare of Indian workers in the Gulf Cooperation Council (GCC) countries remains compromised. The Indian workers continue to face exploitation, often left stranded or forced to return home penniless. In line with best global practices, India’s Bilateral Labour Agreements (BLAs) and Memorandum of Understanding (MoUs) with all the GCC countries need to make specific reference to the host countries' labour laws and facilitate bilateral coordination in the governance of the full migration cycle. Special focus is needed in the construction sector, where a vast majority of low-skilled Indian workers are employed. The article examines the effectiveness of India’s BLAs and MoUs with the GCC countries in protecting the low-skilled Indian workers in the region.
Accuracy of medieval Chinese and Middle-Eastern timings of eclipses
Authors: Morrison Leslie V. , Stephenson F. Richard , Hohenkerk Catherine Y.
Published: December 2021

Analysis of 111 Chinese timings of solar and lunar eclipses in the period AD 434–1280 and of 56 Middle-Eastern timings in AD 829–1020 reveals that their accuracy approached the limiting resolution of their clock systems. The Chinese accuracy improved progressively over the period of observation, with the standard deviation reducing from approximately 18 minutes round about AD 600 to 7 minutes circa AD 1200. The Middle-Eastern timings have a standard deviation of 5 minutes around AD 950.
Obstacles encountered by four major European astronomical observatories belonging to academies in the 18th century
Authors: Chassefière Eric
Published: December 2021

It is known that, in the first half of the 18th century, the conditions for astronomy at the Imperial Observatory of St-Petersburg, directed by Joseph-Nicolas Delisle, were comparable to those enjoyed by astronomers at the royal observatories of Paris and Greenwich created in the previous century. But what about the public observatories created in the first half of the 18th century in Berlin, Uppsala and Bologna? The rich correspondence maintained by Joseph-Nicolas Delisle with the astronomers working in these observatories provides elements of an answer to this question. It also provides more precise information on Delisle’s working conditions at the St-Petersburg Observatory. In this article, we present a comparative analysis of the obstacles encountered by astronomers at these different observatories, and the particular contexts in which they operated, including a breakdown by observatory of salaries and expenditure on astronomy equipment.
Three Gallo-Roman bronze disks with astral inscriptions
Authors: Jones Alexander
Published: December 2021

This article concerns three archaeologically recovered circular bronze objects found at Gallo-Roman (first century BC–fourth century AD) sites in France. Through comparisons with other more or less contemporary objects of known function, it is argued that one of these disks definitely, and another likely, belonged to gearwork devices for keeping track of simple chronological cycles, while the third belonged to a clepsydra of a type recognized only recently.
Electoral support and militants’ targeting strategies
Authors: Aksoy Deniz , Carlson David
Published: December 2021

Militant groups that are in armed conflict with a government often coexist with political parties that have ethnic or ideological connections to them. In this article, we explore the extent to which electoral support received by militant associated opposition parties and nationally incumbent political parties influences subnational variation in militant attacks. We argue, and empirically demonstrate, that militants strategically target localities where the levels of electoral support for the opposition party and the nationally incumbent party are close in an effort to negatively influence the electoral performance of the incumbent party. To illustrate this dynamic we examine subnational data from 1995 to 2015 Turkish legislative elections and attacks organized by the Kurdish militants within the same time period. We also examine the impact of June 2015 legislative elections on militant attacks until the snap elections in November 2015. Our empirical examination shows that militants target localities where electoral support for the governing party and Kurdish opposition party is close. Moreover, increase in violence negatively influences the electoral performance of the governing party. However, it does not consistently have a significant influence on the opposition. The findings illustrate that militants strategically choose the location of their attacks based on electoral dynamics, and attacks can pose an electoral challenge to the governing party.
What Predicts Job Quality of Vocational Rehabilitation Consumers Who Are Blind or Have Low Vision?
Authors: McDonnall Michele C. , Cmar Jennifer L. , McKnight Zhen
Published: December 2021

The U.S. Workforce Innovation and Opportunity Act emphasizes promoting high-quality, competitive employment for people served by vocational rehabilitation (VR), but few studies have assessed VR consumers’ job quality. The purpose of this study was to investigate job quality and factors that predict the job quality for VR consumers with blindness or low vision (B/LV), taking into consideration their employment status at application. We utilized RSA-911 data of VR consumers with B/LV who were closed in competitive employment during 2015, creating two separate hierarchical linear models to predict job quality for VR consumers (a) who were employed at application and (b) who were not employed at application. We investigated individual-level (consumer personal characteristics and VR services) and state/agency-level predictors. Job quality and some predictors of job quality differed by employment status at application, although the strongest predictors (education level at application, gender, benefit receipt at application, receipt of a bachelor’s or higher degree) were consistent across the models. While several additional individual-level variables were significantly associated with job quality, their effect sizes were very small. With the exception of advancing education to a bachelor’s degree or higher while receiving services, consumer characteristics at application were the primary determinants of their job quality.
Advantages of upper-class backgrounds: Forms of capital, school cultures and educational performance
Authors: Jarness Vegard , Strømme Thea Bertnes
Published: December 2021

In this article, we chart connections between class and educational performance in comparatively egalitarian Norway. While viewing various forms of capital as integral parts of class background, we assess how educational performance is differentiated across the class structure. We use survey and register data to assess differences in grades in three school subjects – mathematics and spoken and written Norwegian – at the individual and school level. We focus on the year of graduation of students at lower-secondary schools in Bergen, Norway’s second largest city by population. Lending credence to Bourdieu’s model of the social space, we find differences according to both capital volume and capital composition. Students from class backgrounds rich in overall capital perform comparatively better than those from humbler class backgrounds. There are also differences within the upper class: those from homes rich in cultural capital perform comparatively better than those from homes rich in economic capital. Although between-school differences are low within the ‘unified’ Norwegian school system, the analysis indicates that grades are associated with the class composition of schools: a high proportion of upper-class students positively correlates with higher grades. In addition, there is some evidence of a collective form of class bias: in one of the school subjects, spoken Norwegian, there is a connection between individual grades and teachers’ perceptions of the culture pervasive at the school in question; this connection is contingent upon a school’s class composition. The analysis thus draws attention to the way in which class bias in grading varies between school subjects.
Development of high melt strength polypropylene and its application in thermoplastic elastomeric composition

Published: December 2021

High melt strength polypropylene (HMS-PP) with a long-chain branched structure is a modified form of polypropylene (PP) which has basic properties of regular PP but with superior melt drawability. This paper reports on the development of gel-free HMS-PP from a linear isotactic PP through the introduction of long-chain branching on its backbone via a reactive extrusion process, using dicetyl-peroxydicarbonate (PODIC) alone or in combination with a coagent. The melt strength and the mechanical properties such as impact and flexural strength of PP showed improvements with the modification with PODIC. 5000 ppm by weight of PODIC was found to provide the best balance of properties. The efficacies of zinc diethyldithiocarbamate (ZDC) and tetramethyl thiuram disulphide (TMTD) as coagents in combination with PODIC to augment properties of HMS-PP further were explored. TMTD offered slightly enhanced performance benefits as compared to ZDC at an optimized concentration of 100 ppm by weight. The application potential of HMS-PP in thermoplastic elastomeric blends of HMS-PP with ethylene-propylene-diene monomer (EPDM) rubber at a fixed ratio of 35/65 by weight was also investigated. Structure-property correlations were established between the extent of long-chain branching in the modified PP and the properties of the resultant thermoplastic elastomeric composition.
Using different waste as resilient layers for impact sound insulation improvement: New alternative to commercial layers?
Authors: García-Cobos Francisco José , Maderuelo-Sanz Rubén
Published: December 2021

In the residential building sector, the use of floating floors is a common practice which increasingly used to reduce vibrations and impact noise. These are usually made from industrial materials, although the emerging concern for sustainable construction is leading to the use of other materials from recycled waste. This article studies the performance of rubber, cork, and cigarette butts as a floating floor. For this purpose, their acoustic properties (ISO 9052-1 and 12,354-2 standards) are analyzed and compared with those of some commercial materials. The results obtained indicated that the performance of these eco-materials is equal or superior to that of commercially available materials.
Third Report on the Publication and Conservation of the Tomb of Ramesses III in the Valley of the Kings (KV 11)
Authors: Weber Anke , Hovestreydt Willem , Rees Lea
Published: December 2021

Since antiquity, the tomb of Ramesses III (KV 11) has been among the most frequently visited royal tombs in the Valley of the Kings. It was also one of the first to be described and documented in detail by European travellers in the eighteenth to nineteenth centuries. As large parts of the wall decoration of the tomb, especially in its rear, are now destroyed, the drawings, notes and squeezes of those early researchers who saw the site in its former splendour offer an invaluable resource for the reconstruction of the tomb’s unique decoration programme. The collection, revision, and publication of all relevant archive material concerning KV 11 is an important goal of The Ramesses III (KV 11) Publication and Conservation Project. The following article reports on first and preliminary results from the authors’ research in the archives of the British Library and the Victoria and Albert Museum in London, as well as the Bodleian Libraries and the Griffith Institute in Oxford, carried out in September 2019 and made possible through the Centenary Award 2019 of the Egypt Exploration Society.
Inter-Party Competition, Public Electoral Pressure, and Democratic Strength: Refining Political Explanations of Incarceration Trends in the U.S., 1980 – 2010
Authors: Vasiliev Pavel V.
Published: December 2021

The purpose of this research is to advance the politics of mass imprisonment literature by testing and specifying the macro-explanations of the state-level incarceration change in the United States (U.S.) between 1980 and 2010. Specifically, I account for mechanisms of inter-party competition and public electoral pressure neglected in prior research. To accomplish this goal, I utilize random coefficient models designed to control for repeated annual measures of state-level data that overwhelm traditional analytic techniques. Findings suggest that violent crime, partisan affiliation of state legislators and governors, probation rates, citizen ideology, marijuana decriminalization, and recidivist-focused laws are associated with incarceration as hypothesized, as well as the African American presence net of crime and socioeconomic disadvantage. Contributing to the theoretical debates on democracy and punishment, this paper demonstrates that inter-party competition and public electoral pressure amplify incarceration in the context of Democratic Party dominance, where no liberalizing effects of competition were found. I conclude that legal and extralegal factors are associated with incarceration and suggest that the public did not oppose criminal justice expansion via democratic feedback mechanisms, so both penal populism (Pratt, 2008) and popular punitivism (Campbell et al., 2017) are valid interpretations of imprisonment politics during the analyzed period.
Historical Sociology in Poland: Transformations of the Uses of the Past
Authors: Kolasa-Nowak Agnieszka , Bucholc Marta
Published: December 2021

The development of Polish institutional sociology since the 1920s reflects the combined effects of domestic political and cultural factors, along with international interdependencies. Historical sociology shares in the vicissitudes of the whole discipline. Although historical sociology was only weakly institutionalized before 1989, some of the best sociological studies produced in Poland under socialism display the keen use of historical imagination, inspired both by the pre-1939 domestic tradition and by Marxist theory. This article examines the path of historical sociology in Poland after 1989 and the connection between the sociological uses of history and the experience of post-communist transformation. We posit that the social transformation experience and how it was addressed by social science directly translate into the use of history in Polish sociology after 1989. We argue that the role of historical sociology in Poland since the end of the 1990s was a function of the potential of the past as a symbolic resource in the growing interdependence between Poland and Western Europe. However, the post-1989 research agendas of historical sociology were forged according to the mode of responsiveness to political agendas predating 1989. An overview of the development of Polish historical sociology demonstrates that the ahistorical transitological thinking after 1989 has been challenged by critical agendas in historical sociology, but it was, in the first place, a reaction to the increased potential of the past as a symbolic resource in political debates. Thus, the rationale for the passage to the third wave of historical sociology was primarily political.
The Politics of Student Voice: The Power and Potential of Students as Policy Actors

Published: December 2021

Historically and contemporarily students have been critical to bringing issues of justice in education policy to the fore. Yet, there have been limited formal spaces that elevate student voice scholarship in educational policy. In response, this Politics of Education Association (PEA) Yearbook Issue of Educational Policy aims to serve as a platform for opening up new areas for investigation, especially connections between theory to practice specific to student voice in educational policy and the politics of education. This collection of feature articles and research briefs offer diverse examples of how students are influencing change in education policy and practice, while also presenting the political realities and tensions that emerge when students participate in policy leadership activities.
Cultivating Precarisation: Intersecting Vulnerabilities of Syrian Refugees in the Turkish Agricultural Sector
Authors: Dedeoglu Saniye
Published: December 2021

This article explores how the vulnerabilities of Syrian refugees influence their integration into Turkish labour markets, in particular the agricultural sector. ‘Vulnerable integration’ refers to the inclusion of the most vulnerable migrant labour – women and children – in the face of rivalry among different segments of the precariat to obtain existing agricultural jobs. With a focus on intersectional vulnerabilities and the feminisation of precarisation of Syrian labour in Turkey, I aim to highlight the interconnectedness between women’s production and social reproduction. Therefore, I develop a sociological multidimensional dynamic way of thinking about the integration of Syrian refugee labour in Turkey’s seasonal agricultural labour markets.
Review of air-cooling strategies, combinations and thermal analysis (experimental and analytical) of a permanent magnet synchronous motor
Authors: Gundabattini Edison , Mystkowski Arkadiusz
Published: December 2021

This paper gives a brief review of advanced cooling methods and applications to the permanent magnet synchronous motors (PMSMs), as well as investigates the cooling systems design problem for PMSM systems. Heat sources and losses together with analytical and practical analyses are described. Next, the temperature distribution and its influence on the PMSM is investigated using simulation results. The main part of the paper includes a review of the proposed cooling methods that will release the requirement of heat transfer of the PMSM. The finite element methods (FEM) are applied using the AnSys CFD software to obtain high accuracy thermal model of the PMSM system. The new developed forced air-cooling methods are given in details, which enable to effectively redistribute the temperature and heat transfer increasing the efficiency of the PMSM machine. Examples of CFD simulation are outlined to illustrate the effectiveness and benefits of the strategies developed.

Published: December 2021

Aims

The national PrEP programme launched in Ireland in November 2019 with tenofovir/emtricitabine free to those meeting eligibility criteria. We assessed the impact of the first year of the PrEP programme on new HIV diagnoses in the largest sexual health and HIV service in Ireland.

Methods

A free PrEP service was established in November 2019. We reviewed the number of new diagnoses of HIV between November 2018–2019, before the introduction of the national PrEP programme and compared this with the number of new HIV diagnosis between November 2019–2020.

Results

There were 95 new HIV diagnoses (63.3% MSM) between November 2018 and 2019 and 73 new HIV diagnoses (65.7% MSM) between November 2019 and 2020. There was a statistically significant decline in new HIV diagnoses between the 2 years ( P = 0.0003). 546 patients were prescribed PrEP as of December 2020.106 patients (19.4%) changed their PrEP dosing regimen due to lockdown. 178 individuals (32.6%) had a rectal infection diagnosed.

Conclusion

There has been a reduction in new HIV diagnoses in our cohort (although this has occurred during a global pandemic). It is too early to say if PrEP reduces late presentations of HIV based on our findings. A significant number of rectal infections were identified in the PrEP clinic suggesting ongoing risk despite pandemic restrictions. Further research into sexual practices during COVID-19 is needed to assess if this had an impact on the lower rates of HIV acquisition.

Published: December 2021

Background

HIV and other sexually transmitted infections (STIs) have disproportionately affected communities of men who have sex with men (MSM). We describe HIV and STI prevalence and testing patterns among urban Vietnamese MSM.

Methods

We conducted a cross-sectional community-based study of MSM in Hanoi, Vietnam in 2016. Participants self-reported experiences of social stigma in healthcare settings and previous HIV and STI testing. STI testing included HIV, herpes simplex virus-2 (HSV-2), syphilis, gonorrhea, and chlamydia.

Results

205 MSM participated in the study. STI prevalence was HIV (10%), HSV-2 (4%), syphilis (13%), gonorrhea (34%), and chlamydia (19%). More than half (55%) of participants tested positive for at least one STI. Most participants had been previously tested for HIV or another STI (72%), with 24% previously receiving a positive result. Perceived and enacted social stigma in healthcare contexts was negatively associated with previous HIV or STI testing (adjusted prevalence odds ratio (aPOR): 0.22; 95% confidence interval (CI): 0.10–0.48).

Discussion

High prevalence of STIs was observed among Vietnamese MSM, and perceived and enacted stigma was related to HIV and STI testing. Our findings reaffirm the importance of regular STI screening among this population as well as additional outreach to promote safe HIV and STI healthcare engagement.
Field Experiments on Social Media
Authors: Mosleh Mohsen , Pennycook Gordon , Rand David G.
Published: December 2021

Online behavioral data, such as digital traces from social media, have the potential to allow researchers an unprecedented new window into human behavior in ecologically valid everyday contexts. However, research using such data is often purely observational, which limits its usefulness for identifying causal relationships. Here we review recent innovations in experimental approaches to studying online behavior, with a particular focus on research related to misinformation and political psychology. In hybrid lab-field studies, exposure to social-media content can be randomized, and the impact on attitudes and beliefs can be measured using surveys, or exposure to treatments can be randomized within survey experiments, and their impact on subsequent online behavior can be observed. In field experiments conducted on social media, randomized treatments can be administered directly to users in the online environment (e.g., via social-tie invitations, private messages, or public posts) without revealing that they are part of an experiment, and the effects on subsequent online behavior can then be observed. The strengths and weaknesses of each approach are discussed, along with practical advice and central ethical constraints on such studies.
Twenty Months Into the Pandemic: No SARS-CoV-2 Infections Among Health Care Workers Managing COVID-19 Cases in Bhutan

Published: December 2021

There is no international reporting of SARS-CoV-2 infections in health care workers (HCWs). Estimates suggest that a HCW dies every thirty minutes from COVID-19. This worsened the shortages and burnout of HCWs worldwide. Twenty months into the pandemic, Bhutan recorded over 2600 COVID-19 positive cases and three deaths. About 906 HCWs were directly involved in managing these laboratory confirmed cases but no infections occured amongst this group. This zero infection was possible through the clustered management of positive cases in four national COVID-19 centers, strategic deployment of HCWs, the uninterrupted provision of quality personal protective equipment (PPE) and repeated training on the correct use of PPE. This is an exemplary achievement for a small country with limited expertise and resources.

During the COVID-19 pandemic, infection of farmed mink has become not only an economic issue but also a widespread public health concern. International agencies have advised the use of strict molecular and serosurveillance methods for monitoring the SARS-CoV2 status on mink farms. We developed 2 ELISAs and a duplex protein microarray immunoassay (MI), all in a double-recognition format (DR), to detect SARS-CoV2 antibodies specific to the receptor-binding domain (RBD) of the spike protein and to the full-length nucleoprotein (N) in mink sera. We collected 264 mink serum samples and 126 oropharyngeal samples from 5 Spanish mink farms. In both of the ELISAs and the MI, RBD performed better than N protein for serologic differentiation of mink from SARS-CoV2–positive and –negative farms. Therefore, RBD was the optimal antigenic target for serosurveillance of mink farms.

The ability to distinguish among the subspecies of Pasteurella multocida isolates is important epidemiologically; however, classification at the subspecies level based on the results of conventional biochemical tests (fermentation of sorbitol and dulcitol) is reportedly not accurate in all cases. Therefore, we developed a rapid, multiplex PCR assay to differentiate among the 3 subspecies of P. multocida. The PCR assay includes the P. multocida species–specific primers KMT1SP6 and KMT1T7 as an internal amplification control, with a newly designed gatD (galactitol-1-phosphate-5-dehydrogenase)-specific primer pair (unique for subsp. gallicida), and primers targeting a 16S rRNA gene region specific for subsp. septica. The subspecies specificity of the PCR was demonstrated by applying the test to a collection of 70 P. multocida isolates, including the Heddleston serovar reference strains; all isolates and strains were assigned correctly. The PCR assay is a sensitive, specific, and highly effective method for the identification of P. multocida subspecies, and an alternative to biochemical test–based differentiation. A possible relationship was noticed between P. multocida subspecies and lipopolysaccharide (LPS) genotype; all but one of the subsp. gallicida strains were isolated only from avian hosts and represented L1 LPS genotype. Subsp. multocida and subsp. septica isolates were classified into 5 and 4 different LPS genotypes, respectively, of which L3 was the only LPS genotype shared between these 2 subspecies.
‘The System is Not Set up for the Benefit of Women’: Women’s Experiences of Decision-Making During Pregnancy and Birth in Ireland
Authors: Huschke Susann
Published: December 2021

In this article, I draw on in-depth qualitative interviews with 23 women, conducted in 2019/2020, focusing on their involvement in decision-making during pregnancy and birth. The study is located in Ireland, where comparably progressive national policies regarding informed choice in labour and birth clash with the day-to-day reality of a heavily medicalised, paternalistic maternity care system. I represent the subjective experiences of a diverse group of women through in-depth interview excerpts. In my analysis, I move beyond describing what is happening in the Irish maternity system to discussing why this is happening – relating the findings of the research to the international literature on authoritative knowledge, technocratic hospital cultures and risk-based discourses around birth. In the last section of the article, I offer concrete, empirically grounded and innovative recommendations how to enhance women’s involvement in decision-making.
Predictors of Parent Engagement in Community-Based Parent–Child Interaction Therapy: A Brief Report

Published: December 2021

Despite substantial empirical support, correlates of retention and success in community-based parent–child interaction therapy (PCIT) implementation are not well defined. Widespread application of PCIT necessitates improved understanding of intervention components relating to family outcomes beyond highly controlled research trials. Using data collected as part of routine care, this study examined homework completion, time in intervention, and parent perceptions of pre-intervention behavioral issues as predictors of PCIT completion in a community-based sample. Subjects included 78 parents (49 women and 29 men) of 45 children (20 girls, 25 boys; mean age = 5.53 years) participating in PCIT in an outpatient behavioral health clinic in a small Midwestern U.S. city. Unlike previous controlled trials, homework completion did not predict child behavior growth or intervention completion. Reasons for early termination were examined thematically, and parent stress emerged as a possible avenue for future intervention in helping parents successfully complete PCIT. The issue of intervention dosage was also explored to see if families who prematurely terminated from PCIT still evidenced gains in child behavior.

Background:

Open reduction and internal fixation (ORIF) of the ankle is a common procedure performed to correct ankle fractures in many different patient populations. Diabetes, peripheral vascular disease, and osteoporosis have been identified as risk factors for postoperative complications following surgery for ankle fractures. To date, there have not been any studies evaluating postoperative outcomes in patients with bleeding disorders undergoing operative treatment for ankle fractures. The aim of this study was to determine the postoperative complication rate following ORIF of the ankle in patients with a bleeding disorder vs those without a bleeding disorder.

Methods:

From 2006 to 2018, patients undergoing operative treatment for ankle fracture were identified in the National Surgical Quality Improvement Program database. Two patient cohorts were defined: patients with a bleeding disorder and patients without a bleeding disorder. Patients who underwent either inpatient or outpatient ORIF of the ankle were included in this study. In this analysis, demographics, medical comorbidities, and postoperative complications variables were assessed between the 2 cohorts. Bivariate and multivariate analyses were performed.

Results:

Of 10 306 patients undergoing operative treatment for ankle fracture, 9909 patients (96.1%) had no bleeding disorder whereas 397 patients (3.9%) had a bleeding disorder. Following adjustment on multivariate analysis, compared to patients who did not have a bleeding disorder, those with a bleeding disorder had an increased risk of any postoperative complications (odds ratio [OR] 1.48, 95% confidence interval [CI] 1.05-2.08, P = .024), requirement for postoperative blood transfusion (OR 2.86, 95% CI 1.53-5.36, P = .001), and extended length of hospital stay greater than 5 days (OR 1.46, 95% CI 1.10-1.93, P = .010).

Conclusion:

Patients with bleeding disorders are associated with increased risk of postoperative complications following ORIF for ankle fractures. Determining patient risk factors and creating optimal preoperative and perioperative management plans in patients with bleeding disorders undergoing ORIF can be beneficial in reducing postoperative complications, improving patient outcomes, and reducing overall morbidity.

Transforming Prescription Opioid Practices in Primary Care With Change Theory
Authors: Carpenter Rob E. , Silberman Dave , Takemoto Jody K
Published: December 2021

The opioid epidemic continues to be an ongoing public health crisis. Many primary health care providers aptly serve as the gatekeeper to opioid prescriptions. The opioid epidemic has challenged the primary care profession whilst many of these providers have opted out of opioid prescribing altogether. This unintended consequence affirms erosion to primary care that is vital to the ecosystem of opioid management. The purpose of this study was to understand strategies to deliver opioids safely and effectively. Results indicate primary care providers are uniquely positioned to make a positive opioid impact through focused change initiatives. Five common themes arose from the inductive analysis: (1) provide leadership support; (2) define standard of work; (3) conduct pre-visit reviews; (4) conduct post-visit reviews; and (5) measure progress. Then, each common theme was deductively analyzed through a view of Kotter’s change theory to support an effective proxy for implementing and sustaining chronic opioid therapy in a primary care context. These finding have potential to provide actionable implications for health care management professionals and primary care organizations such as hospitals and group practices.
