Posterior transdural resection of giant calcified thoracic disc herniation in a case series of 12 patients
Authors: Negwer Chiara , Butenschoen Vicki M. , Krieg Sandro M. , Meyer Bernhard
Published: October 2020

Calcified thoracic disc herniations present a rare and challenging entity. Due to the close proximity to the spinal cord and relative narrowing of the spinal canal, the optimal approach remains a matter of debate. While the transthoracic approach is usually preferred, we adapted a new technique described in 2012: the transdural posterior approach. Our aim was to evaluate its benefits in patients with giant thoracic disc protrusions. We retrospectively reviewed all patients treated in our neurosurgical department from July 2012 to March 2020. Demographics, pre- and postoperative clinical status, and operative technique and complications were extracted and analyzed. In total, 12 patients underwent a posterior transdural resection of giant calcified thoracic hard discs between 2012 and 2020. All patients underwent a posterior decompression (laminectomy, hemilaminectomy, or laminoplasty). The median duration of surgery was 152 min. Transient postoperative neurological deterioration occurred in 4 patients, with complete recovery until time of discharge. No patient underwent a surgical revision. The transdural resection of giant calcified thoracic hard discs through a posterior approach provides an excellent decompression with sufficient visualization of the spinal cord and a satisfying postoperative outcome.
Towards enabling a cardiovascular digital twin for human systemic circulation using inverse analysis
Authors: Chakshu Neeraj Kavan , Sazonov Igor , Nithiarasu Perumal
Published: October 2020

An exponential rise in patient data provides an excellent opportunity to improve the existing health care infrastructure. In the present work, a method to enable cardiovascular digital twin is proposed using inverse analysis. Conventionally, accurate analytical solutions for inverse analysis in linear problems have been proposed and used. However, these methods fail or are not efficient for nonlinear systems, such as blood flow in the cardiovascular system (systemic circulation) that involves high degree of nonlinearity. To address this, a methodology for inverse analysis using recurrent neural network for the cardiovascular system is proposed in this work, using a virtual patient database. Blood pressure waveforms in various vessels of the body are inversely calculated with the help of long short-term memory (LSTM) cells by inputting pressure waveforms from three non-invasively accessible blood vessels (carotid, femoral and brachial arteries). The inverse analysis system built this way is applied to the detection of abdominal aortic aneurysm (AAA) and its severity using neural networks.
Scalp Topography of Lower Urinary Tract Sensory Evoked Potentials
Authors: van der Lely Stéphanie , Kessler Thomas M. , Mehnert Ulrich , Liechti Martina D.
Published: October 2020

Impaired lower urinary tract (LUT) afferents often cause LUT symptoms. Assessment of LUT afferent pathways is possible using bipolar cortical sensory evoked potential (SEP) recordings with the active electrode at the vertex during electrical stimulation in the LUT. This study aimed to investigate the topographical distribution and microstates of lower urinary tract sensory evoked potentials (LUTSEPs) using different stimulation frequencies. Ninety healthy subjects (18–36 years old, 40 women) were randomly assigned to one of five stimulation locations [bladder dome; trigone; proximal, membranous (men only) or distal urethra]. Cycles of 0.5 Hz/1.1 Hz/1.6 Hz electrical stimulation were applied using a custom-made catheter. Cortical activity was recorded from 64 surface electrodes. Marker setting was performed manually on an individual subject-level for the P1, N1, and P2 components of vertex recordings. N1 and P2 topographies presented with central negativities and positivities around the vertex. Regarding topographical distribution, Randomization Graphical User interface (RAGU) analyses revealed consistent frequency effects and microstates for N1/P2. Higher stimulation frequencies resulted in decreasing map strength for P1, N1, and P2. LUTSEP topographies suggest central generators in the somatosensory cortex, which are not detectable in a bipolar set-up. The observed frequency effect indicates fiber refractoriness at higher frequencies. The multichannel approach allows more comprehensive assessment of LUTSEPs and might therefore be sensitive to pathological changes. Examinations in patients with LUT symptoms are needed to further investigate this biomarker.
MEmoFC: introducing the Multilingual Emotional Football Corpus
Authors: Braun Nadine , van der Lee Chris , Gatti Lorenzo , Goudbeek Martijn , Krahmer Emiel
Published: October 2020

This paper introduces a new corpus of paired football match reports, the Multilingual Emotional Football Corpus, (MEmoFC), which has been manually collected from English, German, and Dutch websites of individual football clubs to investigate the way different emotional states (e.g. happiness for winning and disappointment for losing) are realized in written language. In addition to the reports, it also contains the statistics for the selected matches. MEmoFC is a corpus consisting of comparable subcorpora since the authors of the texts report on the same event from two different perspectives—the winner’s and the loser’s side, and from an arguably more neutral perspective in tied matches. We demonstrate how the corpus can be used to investigate the influence of affect on the reports through different approaches and illustrate how game outcome influences (1) references to the own team and the opponent, and (2) the use of positive and negative emotion terms in the different languages. The MEmoFC corpus, together with the analyzed aspects of emotional language will open up new approaches for targeted automatic generation of texts.

The successful identification of key challenges for current and future research supports development of novel theories, empirical applications, and appropriate policy designs. It allows establishing a future-oriented research agenda whose ultimate goal is an efficient, equitable, and sustainable use of natural resources. Based on a normative foundation, the paper aims to identify fundamental topics, current trends, and major research gaps to motivate further development of academic work in the field.
General methods and properties to evaluate continuum limits of the 1D discrete time quantum walk
Authors: Manighalam Michael , Kon Mark
Published: October 2020

Models of quantum walks which admit continuous time and continuous spacetime limits have recently led to quantum simulation schemes for simulating fermions in relativistic and nonrelativistic regimes (Molfetta GD, Arrighi P. A quantum walk with both a continuous-time and a continuous-spacetime limit, 2019). This work continues the study of relationships between discrete time quantum walks (DTQW) and their ostensive continuum counterparts by developing a more general framework than was done in Molfetta and Arrighi (A quantum walk with both a continuous-time and a continuous-spacetime limit, 2019) to evaluate the continuous time limit of these discrete quantum systems. Under this framework, we prove two constructive theorems concerning which internal discrete transitions (“coins”) admit nontrivial continuum limits. We additionally prove that the continuous space limit of the continuous time limit of the DTQW can only yield massless states which obey the Dirac equation. Finally, we demonstrate that for general coins the continuous time limit of the DTQW can be identified with the canonical continuous time quantum walk when the coin is allowed to transition through the continuous limit process.
A Thematic Analysis of Sports Bettors’ Perceptions of Sports Betting Marketing Strategies in the UK
Authors: Killick Elizabeth A. , Griffiths Mark D.
Published: October 2020

In the UK and other countries in the world, the volume of gambling advertisements is increasing, as is the popularity of online sports betting. While there is increasing research examining the content of such advertising, there is little research examining what gamblers themselves think about such advertising. Consequently, the aim of the present study was to firstly, explore the attitudes and opinions of sports bettors in response to marketing techniques used by the gambling industry and secondly, explore the perceived impact advertising has on their sports betting behavior. Semi-structured interviews were conducted with a sample of 19 UK sports bettors aged between 21 and 32 years old. Thematic analysis (TA) was used to analyze the transcripts. The analysis identified three main themes: (i) “temptation to gamble,” (ii) “promotion characteristics of gambling,” and (iii) “regulating gambling advertising.” Each theme consisted of two or three subthemes that illustrated the underlying factors that were perceived to be important aspects that contributed to the opinions and attitudes towards the advertising. Findings indicate that specific inducements including enhanced odds and “request-a-bet” promotions were perceived to increase feelings of control and reduce feelings of risk, in some cases resulting in the placing of impulsive bets. According to the participants, social media marketing was found to be intrusive and the frequency of gambling advertising contributed to the normalization of betting. The present study highlights the need for further research into the efficacy of current advertising regulations in the UK, with the end goal of minimizing gambling-related harm.

Published: October 2020

Purpose

Persistent fatigue among colorectal cancer (CRC) patients might be associated with unfavorable body composition, but data are sparse and inconsistent. We studied how skeletal muscle index (SMI), skeletal muscle radiodensity (SMR), visceral adipose tissue (VAT), and subcutaneous adipose tissue (SAT) at diagnosis are associated with fatigue up to 24 months post-diagnosis in stage I–III CRC patients.

Methods

SMI, SMR, VAT, and SAT were assessed among 646 CRC patients using pre-treatment computed tomography images. Fatigue at diagnosis, at 6, and 24 months post-diagnosis was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire. The association of SMI, SMR, VAT, and SAT with fatigue (yes/no) was assessed using confounder-adjusted restricted cubic spline analyses.

Results

Prevalence of fatigue at diagnosis was 18%, at 6 months 25%, and at 24 months 12%. At diagnosis, a significant (p = 0.01) non-linear association of higher levels of SAT with higher prevalence of fatigue was observed. Lower levels of SMR were linearly associated with higher prevalence of fatigue at 6 months post-diagnosis (overall associationp = 0.02). None of the body composition parameters were significantly associated with fatigue at 24 months.

Conclusion

Having more SAT was associated with more fatigue at diagnosis, while low levels of SMR were associated with more fatigue at 6 months post-diagnosis.

Implications for Cancer Survivors

Our results suggest that it may be interesting to investigate whether interventions that aim to increase SMR around the time of diagnosis may help to lower fatigue. However, more knowledge is needed to understand the mechanisms behind the association of SMR with fatigue.

The main goal of this paper is to provide an abstract framework for constructing proof systems for various many-valued logics. Using the framework it is possible to generate strongly complete proof systems with respect to any finitely valued deterministic and non-deterministic logic. I provide a couple of examples of proof systems for well-known many-valued logics and prove the completeness of proof systems generated by the framework.
Two Sides of the Same Coin or Two Different Currencies? Representations of Happiness and Unhappiness among Finnish Women
Authors: De Paola Jennifer , Wagner Wolfgang , Pirttilä-Backman Anna-Maija , Lehtonen Josetta
Published: October 2020

This paper presents results from a study exploring representations of “happiness” and “unhappiness.” Word associations with these concepts were produced by 16–18 and 29–34-year-old women from Finland, the country that the United Nation’s World Happiness Report has ranked the “happiest” in the world. Correspondence Analysis (CA) and Hierarchical Cluster Analysis show that participants in both age groups share three clusters of words associated with “happiness”: Tangible happiness, Affective happiness and Serene happiness. We noted more differences in the associations with “unhappiness,” for which the two groups share only two clusters: Loss and Everyday problems. A distinct third cluster, Affective unhappiness, emerged for the younger women, whereas older women’s associations are further differentiated into a more complex structure, including two more clusters: Dejection and Apprehension. Additionally, CA shows that in both age groups, self-reported happiness levels do not discriminate which words are associated with happiness and unhappiness. Finally, qualitative content analysis of a questionnaire item investigating how to reach complete happiness suggested that there are three recurring answer types: happiness can be improved through external changes, internal changes, or not at all because complete/permanent happiness does not exist. The study provides a methodological design which, unlike most happiness studies, allows participants the freedom to bring up the meaning of happiness and unhappiness. Thus, the study constitutes a contribution to a more nuanced understanding of happiness.
Exposure to Armed Conflict and Fertility in Sub-Saharan Africa
Authors: Thiede Brian C. , Hancock Matthew , Kodouda Ahmed , Piazza James
Published: October 2020

Changes in fertility patterns are hypothesized to be among the many second-order consequences of armed conflict, but expectations about the direction of such effects are theoretically ambiguous. Prior research, from a range of contexts, has also yielded inconsistent results. We contribute to this debate by using harmonized data and methods to examine the effects of exposure to conflict on preferred and observed fertility outcomes across a spatially and temporally extensive population. We use high-resolution georeferenced data from 25 sub-Saharan African countries, combining records of violent events from the Armed Conflict Location and Event Data Project (ACLED) with data on fertility goals and outcomes from the Demographic and Health Surveys (n = 368,765 women aged 15–49 years). We estimate a series of linear and logistic regression models to assess the effects of exposure to conflict events on ideal family size and the probability of childbearing within the 12 months prior to the interview. We find that, on average, exposure to armed conflict leads to modest reductions in both respondents’ preferred family size and their probability of recent childbearing. Many of these effects are heterogeneous between demographic groups and across contexts, which suggests systematic differences in women’s vulnerability or preferred responses to armed conflict. Additional analyses suggest that conflict-related fertility declines may be driven by delays or reductions in marriage. These results contribute new evidence about the demographic effects of conflict and their underlying mechanisms, and broadly underline the importance of studying the second-order effects of organized violence on vulnerable populations.
Angiopoietin-like 8 (ANGPTL8) as a potential predictor of NAFLD in paediatric patients with Prader-Willi Syndrome
Authors: Mele C. , Crinò A. , Fintini D. , Mai S. , Convertino A. , Bocchini S. , Di Paolo P. , Grugni G. , Aimaretti G. , Scacchi M. , Marzullo P.
Published: October 2020

Purpose

Angiopoietin-like 8 (ANGPTL8) is a liver- and adipose tissue-produced protein that predicts non-alcoholic fatty liver disease (NAFLD) and altered metabolic homeostasis in the general population as well as in persons with common and genetic obesity, including the Prader–Willi syndrome (PWS). However, its metabolic correlate in paediatric patients with respect to PWS is unknown.

Methods

This cross-sectional study investigated circulating ANGPTL8 and adipocytokines levels in 28 PWS and 28 age-, sex- and BMI-matched children and adolescents (age, 7.0–17.8y) in relation to NAFLD and metabolic homeostasis assessed by OGTT, paediatric metabolic index (PMI) and fatty liver index (FLI), liver ultrasonography (US), as well as dual-energy X-ray absorptiometry (DEXA) for analysis of fat (FM) and fat-free mass (FFM).

Results

At the set level of significance, PWS children showed lower values of FFM (p < 0.01) but healthier insulin profiles (p < 0.01) and PMI values (p < 0.05) than matched controls. By US, the prevalence of NAFLD was similar between groups but less severe in PWS than controls. Analysis of ANGPTL8 levels showed no difference between groups, yet only in PWS ANGPTL8 levels were associated with ALT levels, FLI values and NAFLD. In stepwise multivariable regression analysis on merged data, ANGPTL8 levels were independently predicted by BMI SDS, leptin levels and NAFLD.

Conclusion

ANGPTL8 levels are similar in PWS and controls and, overall, they are directly associated with the presence and severity of NAFLD in patients with PWS.
Voice Pitch – A Valid Indicator of One’s Unfaithfulness in Committed Relationships?
Authors: Schild Christoph , Stern Julia , Penke Lars , Zettler Ingo
Published: October 2020

Objectives

When judging a male speakers’ likelihood to act sexually unfaithful in a committed relationship, listeners rely on the speakers’ voice pitch such that lower voice pitch is perceived as indicating being more unfaithful. In line with this finding, a recent study (Schild et al. Behavioral Ecology, 2020) provided first evidence that voice pitch might indeed be a valid cue to sexual infidelity in men. In this study, male speakers with lower voice pitch, as indicated by lower mean fundamental frequency (mean F0), were actually more likely to report having been sexually unfaithful in the past. Although these results fit the literature on vocal perceptions in contexts of sexual selection, the study was, as stated by the authors, underpowered. Further, the study solely focused on male speakers, which leaves it open whether these findings are also transferable to female speakers.

Methods

We reanalyzed three datasets (Asendorpf et al. European Journal of Personality, 25, 16–30, 2011; Penke and Asendorpf Journal of Personality and Social Psychology, 95, 1113–1135, 2008; Stern et al. 2020) that include voice recordings and infidelity data of overall 865 individuals (63,36% female) in order to test the replicability of and further extend past research.

Results

A significant negative link between mean F0 and self-reported infidelity was found in only one out of two datasets for men and only one out of three datasets for women. Two meta-analyses (accounting for the sample sizes and including data of Schild et al. 2020), however, suggest that lower mean F0 might be a valid indicator of higher probability of self-reported infidelity in both men and women.

Conclusions

In line with prior research, higher masculinity, as indicated by lower mean F0, seems to be linked to self-reported infidelity in both men and women. However, given methodological shortcomings, future studies should set out to further delve into these findings.
Burns Depth Assessment Using Deep Learning Features
Authors: Abubakar Aliyu , Ugail Hassan , Smith Kirsty M. , Bukar Ali Maina , Elmahmudi Ali
Published: October 2020

Purpose

Burns depth evaluation is a lifesaving task and very challenging that requires objective techniques to accomplish. While the visual assessment is the most commonly used by surgeons, its accuracy reliability ranges between 60 and 80% and subjective that lacks any standard guideline. Currently, the only standard adjunct to clinical evaluation of burn depth is Laser Doppler Imaging (LDI) which measures microcirculation within the dermal tissue, providing the burns potential healing time which correspond to the depth of the injury achieving up to 100% accuracy. However, the use of LDI is limited due to many factors including high affordability and diagnostic costs, its accuracy is affected by movement which makes it difficult to assess paediatric patients, high level of human expertise is required to operate the device, and 100% accuracy possible after 72 h. These shortfalls necessitate the need for objective and affordable technique.

Method

In this study, we leverage the use of deep transfer learning technique using two pretrained models ResNet50 and VGG16 for the extraction of image patterns (ResFeat50 and VggFeat16) from a a burn dataset of 2080 RGB images which composed of healthy skin, first degree, second degree and third-degree burns evenly distributed. We then use One-versus-One Support Vector Machines (SVM) for multi-class prediction and was trained using 10-folds cross validation to achieve optimum trade-off between bias and variance.

Results

The proposed approach yields maximum prediction accuracy of 95.43% using ResFeat50 and 85.67% using VggFeat16. The average recall, precision and F1-score are 95.50%, 95.50%, 95.50% and 85.75%, 86.25%, 85.75% for both ResFeat50 and VggFeat16 respectively.

Conclusion

The proposed pipeline achieved a state-of-the-art prediction accuracy and interestingly indicates that decision can be made in less than a minute whether the injury requires surgical intervention such as skin grafting or not.
Review of solid oxide fuel cell materials: cathode, anode, and electrolyte
Authors: Hussain Saddam , Yangping Li
Published: October 2020

There is a growing interest in solid oxide fuel cells (SOFCs) technology among the researchers a promising power generation with high energy efficiency, inflated fuel flexibility, and low environmental impact compared to conventional power generation systems. SOFCs are devices in which the chemical energy is directly converted into electrical energy with negligible emission. SOFCs have low pollution characteristics, high efficiency (~ 60%), and possess expanded fuel selection with little environmental effects. A single cell component of SOFCs is consisting an anode, cathode and an electrolyte which are stacked layer by layer to produce higher amount of power. The dense ceramic electrolyte transporting O2− ions and fills the space between the electrodes material. Redox reaction occurred at the electrodes side in the presence of fuels. The operating temperatures of SOFCs of 600–1200 °C which produced heat as a byproduct and fast electro-catalytic activity while using nonprecious metals. Many ceramic materials have been investigated for SOFCs electrolyte. Yttria-stabilized zirconia (YSZ) material was extensively used as dense electrolyte in SOFCs technology. In this review, the article presents; overview of the SOFCs devices and their related materials and mostly reviewed newly available reported.
Safe areas for the protection of civilians. An overview of existing research and scholarship
Authors: Hering Robin
Published: October 2020

Safe areas for the protection of civilians remain a possible instrument in the foreign policy-making toolbox. Lately, this was highlighted by calls for a safe area in Syria by German chancellor Angela Merkel and defence minister Annegret Kramp-Karrenbauer. Yet, the subsequent debates demonstrated that many policy-makers, pundits and scholars lack a detailed knowledge about the concept. They further showed that various different perspectives on the idea of safe areas exist. This article therefore provides a comprehensive and inclusive account of the academic engagement with the topic of safe areas. It demonstrates that some arguments focus on the (geo)political dynamics of safe areas, whereas others emphasise the potential to protect civilians. It further presents the legal codification of consent-based safe areas in the Geneva Conventions as well as debates about the legality of enforced, post-Cold War safe area cases. Regarding the research on displacement and safe areas, the majority tends to focus on the containment effects, although some highlight the capacity of safe areas as an alternative to flight. Overall, however, the article concludes that recent and conceptual academic engagement with safe areas remains rare and that a safe area perspective is missing in relevant current empirical cases. More research that contributes to the conceptual development of safe areas or to the assessment of current empirical examples, for instance in South Sudan, is necessary.
Implementation of Thin-Walled Approximation to Evaluate Properties of Complex Steel Sections Using C++
Authors: Siddiqui Shahida Anusha , Ahmad Ali
Published: October 2020

Steel sections have several applications in the construction industry. They are often used in the design and construction of huge industrial complexes. They also are used in transport, shipbuilding and packaging industries. Typical steel sections are used, and their properties have been recorded and are not needed to be calculated per application. They are recorded in most design software and used easily when required. This work focusses on using thin-walled approximation to calculate the section properties of complex sections which are a combination of existing section profiles. A program is written using C++ which would apply dimensions from the user and display the section properties at the end as result. The aim is to automate the process to calculate the required values and this would in turn save time. The values obtained from the program are compared with those calculated using existing formulas and the error obtained is reported.
Is Pornography Consumption Related to Risky Behaviors During Friends with Benefits Relationships?
Authors: Henderson Elena , Aaron Sean , Blackhurst Zachary , Maddock Meghan , Fincham Frank , Braithwaite Scott R.
Published: October 2020

Background

Friends with benefits encounters are a relatively new pattern of relating among emerging adults where risky sexual behavior may occur.

Aim

To understand whether pornography consumption is associated with riskier behaviors during friends with benefits encounters.

Methods

Cross-sectional study of 2 samples of emerging adults who have engaged in friends with benefits relationships (study 1, N = 411; study 2, N = 394). For binary outcomes, we used logistic regression and report odds ratios. For ordinal outcomes, we used ordered logistic regression and reported odds ratios. We tested for moderation by biological sex.

Results

Men who consumed pornography more frequently were more likely to engage in risky sexual behaviors during their friends with benefits encounters. More frequent pornography consumption was associated with increased likelihood and amount of intoxication for both the respondent and his partner, less frequent condom use, and a higher probability of having penetrative friends with benefits encounters while intoxicated and not using a condom. For each of these outcomes, our parameter estimates from study 2 fell within the 95% confidence intervals from study 1. These associations persisted when controlling for the effects of binge drinking frequency, broader patterns of problematic alcohol use, trait self-control, openness to experience, and permissive attitudes toward casual sex. The findings of this study may inform interventions to reduce risky behaviors among emerging adults.

Limitations

Our cross-sectional studies examined only emerging adults in college with measurement that was exclusively self-reported.

Conclusions

These results are discussed in terms of sexual script theory, and several implications for intervention are outlined.
Land Acquisition and Resource Development in Contemporary India
Authors: Singh Shashi Ratnaker
Published: October 2020

This book derives from research and fieldwork in the rural and tribal hinterland of India, particularly in the mineral rich states. It looks at the nuances of land and resource politics and summarizes the long-standing land acquisition and mining debate. It discusses the relevant theoretical arguments from inter-disciplinary perspectives and develops an argument through the case study of Singrauli, a region in Madhya Pradesh in India, that has seen various 'regimes of dispossession' in the last six decades in India. It looks at the legal and policy arguments around right to property, 'fair' compensation, public purpose and the resource curse debate, and at contested 'spaces' (left wing extremism) and resource-capital relationships.
Winning Lebanon
Authors: Baun Dylan
Published: October 2020

By the mid-twentieth century, youth movements around the globe ruled the streets. In Lebanon, young people in these groups attended lectures, sang songs, and participated in sporting events; their music tastes, clothing choices and routine activities shaped their identities. Yet scholars of modern Lebanon often focus exclusively on the sectarian makeup and violent behaviors of these socio-political groupings, obscuring the youth cultures that they forged. Using unique sources to highlight the daily lives of the young men and women of Lebanon's youth politics, Dylan Baun traces the political and cultural history of a diverse set of youth-centric organizations from the 1920s to 1950s to reveal how these youth movements played significant roles in the making of the modern Middle East. Outlining how youth movements established a distinct type of politics and populism, Winning Lebanon reveals that these groups both encouraged the political socialization of different types of youth, and, through their attempts to 'win' Lebanon - physically and metaphorically - around the 1958 War, helped produce sectarian violence.
The Antebellum Origins of the Modern Constitution
Authors: Gilhooley Simon J.
Published: October 2020

This book argues that conflicts over slavery and abolition in the early American Republic generated a mode of constitutional interpretation that remains powerful today: the belief that the historical spirit of founding holds authority over the current moment. Simon J. Gilhooley traces how debates around the existence of slavery in the District of Columbia gave rise to the articulation of this constitutional interpretation, which constrained the radical potential of the constitutional text. To reconstruct the origins of this interpretation, Gilhooley draws on rich sources that include historical newspapers, pamphlets, and congressional debates. Examining free black activism in the North, Abolitionism in the 1830s, and the evolution of pro-slavery thought, this book shows how in navigating the existence of slavery in the District and the fundamental constitutional issue of the enslaved's personhood, Antebellum opponents of abolition came to promote an enduring but constraining constitutional imaginary.
Eucharist and Receptive Ecumenism
Authors: Belcher Kimberly Hope
Published: October 2020

All doctrinal development and debate occurs against the background of Christian practice and worship. By attending to what Christians have done in the eucharist, Kimberly Belcher provides a new perspective on the history of eucharistic doctrine and Christian divisions today. Stepping back from the metaphysical approaches that divide the churches, she focuses on a phenomenological approach to the eucharist and a retrieval of forgotten elements in Ambrose's and Augustine's work. The core of the eucharist is the act of giving thanks to the Father – for the covenant and for the world. This unitive core allows for significant diversity on questions about presence, sacrifice, ecclesiology, and ministry. Belcher shows that the key is humility about what we know and what we do not, which gives us a willingness to receive differences in Christian teachings as gifts that will allow us to move forward in a new way.
Elections, Protest, and Authoritarian Regime Stability
Authors: Smyth Regina
Published: October 2020

In a path-breaking study of Russian elections, Regina Smyth reveals how much electoral competition matters to the Putin regime and how competition leaves Russia more vulnerable to opposition challenges than is perceived in the West. Using original data and analysis, Smyth demonstrates how even weak political opposition can force autocratic incumbents to rethink strategy and find compromises in order to win elections. Smyth challenges conventional notions about Putin's regime, highlighting  the vast resources the Kremlin expends to maintain a permanent campaign to construct regime-friendly majorities. These tactics include disinformation as well as symbolic politics, social benefits, repression, and falsification. This book reveals the stresses and challenges of maintaining an electoral authoritarian regime and provides a roadmap to understand how seemingly stable authoritarian systems can fall quickly to popular challenges even when the opposition is weak. A must-read for understanding Russia's future and the role of elections in contemporary autocratic regimes.
The Idea of Development in Africa
Authors: Decker Corrie , McMahon Elisabeth
Published: October 2020

The Idea of Development in Africa challenges prevailing international development discourses about the continent, by tracing the history of ideas, practices, and 'problems' of development used in Africa. In doing so, it offers an innovative approach to examining the history and culture of development through the lens of the development episteme, which has been foundational to the 'idea of Africa' in western discourses since the early 1800s. The study weaves together an historical narrative of how the idea of development emerged with an account of the policies and practices of development in colonial and postcolonial Africa. The book highlights four enduring themes in African development, including their present-day ramifications: domesticity, education, health, and industrialization. Offering a balance between historical overview and analysis of past and present case studies, Elisabeth McMahon and Corrie Decker demonstrate that Africans have always co-opted, challenged, and reformed the idea of development, even as the western-centric development episteme presumes a one-way flow of ideas and funding from the West to Africa.
A Gap in Post-Stroke Blood Pressure Target Attainment at Entry to Cardiac Rehabilitation
Authors: Sawicki Carolyn , Oh Paul , Marzolini Susan
Published: October 2020

Background:

Recurrent events account for approximately one-third of all strokes and are associated with greater disability and mortality than first-time strokes. Blood pressure (BP) is the most important modifiable risk factor. Objectives were to determine the proportion of post-stroke patients enrolled in cardiac rehabilitation (CR) meeting systolic and diastolic BP (SBP/DBP) targets and to determine correlates of meeting these targets.

Methods:

A retrospective study of 1,804 consecutively enrolled post-stroke patients in a CR program was conducted. Baseline data (database records 2006–2017) included demographics, anthropometrics, clinical/medication history, and resting BP. Multivariate analyses determined predictors of achieving BP targets.

Results:

Mean age was 64.1 ± 12.7 years, median days from stroke 210 (IQR 392), with most patients being male (70.6%;n= 1273), overweight (66.8%;n= 1196), and 64.2% diagnosed with hypertension (n= 1159), and 11.8% (n= 213) with sleep apnea. A mean of 1.69 ± 1.2 antihypertensives were prescribed, with 26% (n= 469) of patients prescribed 3–4 antihypertensives. SBP target was met by 71% (n= 1281) of patients, 83.3% (n= 1502) met DBP target, and 64.3% (n= 1160) met both targets. Correlates of meeting SBP target were not having diabetes, younger age, fewer prescribed antihypertensives, and more recent program entry. Correlates of meeting DBP target were not having diabetes, older age, fewer prescribed antihypertensives, and more recent stroke.

Conclusions:

Up to one-third of patients were not meeting BP targets. Patients with diabetes, and those prescribed multiple antihypertensives are at greater risk for poorly controlled SBP and DBP. Reasons for poor BP control such as untreated sleep apnea and medication non-adherence need to be investigated.
A new ammonite from the Penarth Group, South Wales and the base of the Jurassic System in SW Britain
Authors: Hodges Peter

Two ammonites have been found in porcelaneous limestones of the White Lias Formation traditionally considered to be of Rhaetian (Late Triassic) age at Lavernock Point, south Wales (ST 181 681). These ammonites, named here Neophyllites lavernockensis. sp. nov, are the earliest recorded from the UK. This horizon is located directly above a major negative δ13C isotope anomaly (CIE1) in the Upper Cotham Member that marks the top of the Triassic System and below another negative δ13C isotope anomaly (CIE3). Both correlate with negative δ13C isotope anomalies in the Triassic–Jurassic global boundary stratotype section and point (GSSP) at Kuhjoch, Austria. This establishes the base of the tilmanni Chronozone, Hettangian Stage and Jurassic System in SW Britain within the White Lias Formation at Lavernock Point.
A descriptive account of the Quebec French diphthongfête
Authors: Riverin-Coutlée Josiane , Roy Johanna-Pascale

Diphthongization has a long history in Quebec French. In this variety, lengthened vowels have the potential to be diphthongized. However, one vowel stands out, as it is always long and seems particularly inclined to be diphthongal: thefêtevowel. While it has been much studied over the years, some uncertainties remain in the literature, especially whether length or quality primarily distinguishes it and which phonetic transcription appropriately reflects the way Quebec French speakers pronounce it today. This study addresses these issues by drawing a parallel between acoustic properties of thefêtevowel and those of other vowels produced in similar consonantal contexts by 52 native speakers of Quebec French. After analyzing 8866 tokens, we present a descriptive account of their relative duration, location in F1/F2 planes and spectral changes. The results show thatfêteis, in fact, acoustically distinct, but more in terms of the spectral changes that occur than its duration. Its first two formants extensively shift between 25% and 75% of its duration, with a substantial F2 increase and F1 decrease. In F1/F2 planes,fêtehas onset values similar to /a/ and offset values similar to /ɛ/. Therefore, we argue that the two most commonly used phonological transcriptions for this singular vowel, /ɜ/ and /ɛː/, present some problems and do not capture its characterizing features. Drawing on our results and the IPA vowel chart, we suggest a more accurate symbol.
Altered neuronal activity in the visual processing region of eye-fluke-infected fish

Fish, like most vertebrates, are dependent on vision to varying degrees for a variety of behaviours such as predator avoidance and foraging. Disruption of this key sensory system therefore should have some impact on the ability of fish to execute these tasks. Eye-flukes, such as Tylodelphys darbyi, often infect fish where they are known to inflict varying degrees of visual impairment. In New Zealand, T. darbyi infects the eyes of Gobiomorphus cotidianus, a freshwater fish, where it resides in the vitreous chamber between the lens and retina. Here, we investigate whether the presence of the parasite in the eye has an impact on neuronal information transfer using the c-Fos gene as a proxy for neuron activation. We hypothesized that the parasite would reduce visual information entering the eye and therefore result in lower c-Fos expression. Interestingly, however, c-Fos expression increased with T. darbyi intensity when fish were exposed to flashes of light. Our results suggest a mechanism for parasite-induced visual disruption when no obvious pathology is caused by infection. The more T. darbyi present the more visual stimuli the fish is presented with, and as such may experience difficulties in distinguishing various features of its external environment.

In this paper, with the aim to find new genes involved in mammalian spermatogenesis, we isolated, for the first time in the rat testis, a partial cDNA clone that encoded EH domain binding protein 1-like 1 (Ehbp1l1), a protein that has a single calponin homology domain (CH). Bioinformatic analysis showed that EHBP1l1 contains three domains: the N-terminal C2-like, the CH and the C-terminal bivalent Mical/EHBP Rab binding (bMERB) domains, which are evolutionarily conserved in vertebrates. We found that Ehbp1l1 mRNA was expressed in several rat tissues, including the liver, intestine, kidney and also in the testis during its development, with a higher level in testis from 12-month-old animals. Interestingly,in situhybridization experiments revealed that Ehbp1l1 is specifically expressed by types I and II spermatocytes, this result was validated by RT-PCR performed on total RNA obtained from enriched fractions of different testicular cell types. As EHBP1l1 has been described as linked to vesicular transport to the actin cytoskeleton and as an effector of the small GTPase Rab8, we hypothesized that it could participate both in cytoskeletal remodelling and in the regulation of vesicle sorting from thetrans-Golgi network to the apical plasma membrane. Our findings provide a better understand of the molecular mechanisms of the differentiation process of spermatogenesis; Ehbp1l1 may also be used as a new marker of testicular activity.
Large symptomatic coronary artery fistulas draining to the left heart: transcatheter management

Published: October 2020

Large coronary artery fistulas draining to the left heart structures causing heart failure are very rare. Interventional closure of such fistulas is limited to isolated reports, often in asymptomatic patients. Technical differences in these interventions include either deep arterial cannulation till their exit or transseptal arteriovenous circuit formation. Transcatheter closure of three large symptomatic fistulas in small children is reported.
Language control in bilingual production: Insights from error rate and error type in sentence production
Authors: Martin Clara D. , Nozari Nazbanou
Published: October 2020

Most research showing that cognates are named faster than non-cognates has focused on isolated word production which might not realistically reflect cognitive demands in sentence production. Here, we explored whether cognates elicit interference by examining error rates during sentence production, and how this interference is resolved by language control mechanisms. Twenty highly proficient Spanish–English bilinguals described visual scenes with sentence structures ‘NP1-verb-NP2’ (NP = noun-phrase). Half the nouns and half the verbs were cognates and two manipulations created high control demands. Both situations that demanded higher inhibitory control pushed the cognate effect from facilitation towards interference. These findings suggest that cognates, similar to phonologically similar words within a language, can induce not only facilitation but robust interference.

Published: October 2020

Objective:

To determine the optimal anthropometric cut-off points for predicting the likelihood ratios of hypertension and diabetes in the Peruvian population.

Design:

A cross-sectional study was performed to establish cut-off values for body mass index (BMI), waist circumference (WC), waist:height ratio (WHtR) and Conicity index (C-index) associated with increased risk of hypertension and diabetes. Youden’s index (YIndex), area under the curve (AUC), sensitivity and specificity were calculated.

Setting:

Peruvian households.

Participants:

Peruvian population over the age of 18 years.

Results:

A total of 31 553 subjects were included, 57 % being women. Among the women, 53·06 % belonged to the 25- to 44-year-old age group [mean age: 41·66 in men and 40·02 in women]. The mean BMI, WHtR and C-index values were higher in women 27·49, 0·61, 1·30, respectively, while the mean WC value was higher in men 92·12 cm (sd± 11·28). The best predictors of hypertension in men were the WHtR (AUC = 0·64) and the C-index (AUC = 0·64) with an optimal cut-off point of 0·57 (YIndex = 0·284) and 1·301 (YIndex = 0·284), respectively. Women showed an AUC of 0·63 and 0·61 in the WHtR and C-index, respectively, with an optimal cut-off of 0·61 (YIndex = 0·236) and 1·323 (YIndex = 0·225). The best predictor for diabetes was the C-index: with an AUC = 0·67 and an optimal cut-off of 1·337 (YIndex = 0·346) for men and an AUC = 0·66 and optimal cut-off of 1·313 (YIndex = 0·319) for women.

Conclusions:

Our findings show that in Peruvian adults, the WHtR and the C-index have the strongest association with hypertension in both sexes. Likewise, the C-index had the strongest association with diabetes.
Trends in cyclical food expenditures among low-income households receiving monthly nutrition assistance: results from a prospective study
Authors: Valluri Sruthi , Mason Susan M , Peterson Hikaru H , French Simone A , Harnack Lisa J
Published: October 2020

Objective:

Supplemental Nutrition Assistance Program (SNAP) benefits are rapidly depleted after distribution. This phenomenon, known as the benefit cycle, is associated with poor nutrition and health outcomes. However, to date, no study has evaluated trends in food expenditures before and after households receive benefits using prospective data, and whether these trends vary by household characteristics.

Design:

Generalised estimating equations were used to model weekly household food expenditures during baseline (pre-benefit) and intervention months by vendor (restaurants and food retailers). Food retailer expenditures were further evaluated by food category (fruits and vegetables and foods high in added sugar). All expenditures were evaluated by household composition, demographics and economic means.

Setting:

Minneapolis-St. Paul, Minnesota, metropolitan area.

Participants:

Low-income households (n249) enrolled May 2013–August 2015.

Results:

Weekly food retailer expenditures did not vary during baseline (pre-benefit), but demonstrated a cyclical pattern after households received benefits across all household characteristics and for both food categories, particularly for fruits and vegetables. Households with greater economic resources spent more throughout the month compared with those with fewer resources. Households with lower food security status experienced more severe fluctuations in spending compared with more food secure households.

Conclusions:

Cyclical food purchasing was observed broadly across different household characteristics and food categories, with notable differences by household economic means and food security status. Proposed SNAP policy changes designed to smooth food expenditures across the benefit month, such as increased frequency of benefit distribution, should include a focus on households with fewest resources.
