Published: January 2021

AbstractSentic computing relies on well-defined affective models of different complexity—polarity to distinguish positive and negative sentiment, for example, or more nuanced models to capture expressions of human emotions. When used to measure communication success, even the most granular affective model combined with sophisticated machine learning approaches may not fully capture an organisation’s strategic positioning goals. Such goals often deviate from the assumptions of standardised affective models. While certain emotions such asJoyandTrusttypically represent desirable brand associations, specific communication goals formulated by marketing professionals often go beyond such standard dimensions. For instance, the brand manager of a television show may considerfearorsadnessto be desired emotions for its audience. This article introduces expansion techniques for affective models, combining common and commonsense knowledge available in knowledge graphs with language models and affective reasoning, improving coverage and consistency as well as supporting domain-specific interpretations of emotions. An extensive evaluation compares the performance of different expansion techniques: (i) a quantitative evaluation based on the revisitedHourglass of Emotionsmodel to assess performance on complex models that cover multiple affective categories, using manually compiled gold standard data, and (ii) a qualitative evaluation of a domain-specific affective model for television programme brands. The results of these evaluations demonstrate that the introduced techniques support a variety of embeddings and pre-trained models. The paper concludes with a discussion on applying this approach to other scenarios where affective model resources are scarce.
Falling through the Cracks: Dealing with the Problem of the Unclassifieds in RELTRAD
Authors: Burge Ryan P. , Djupe Paul 
Published: January 2021

Background RELTRAD is the most popular and widely used classification scheme for sorting religious traditions in the social sciences, however it struggles with how to sort non-denominational Protestants into one of the existing categories, with a growing number falling into an often ignored “unclassified” category. Purpose To demonstrate the growing problem of excluding non-denominational protestants who attend infrequently in the current iteration of RELTRAD. We assess the assumption that the “unclassified” respondents are akin to those who select a “don't know” option and should be excluded. We also propose several ways to reintroduce low attending non-denominationals back into the larger sample. Methods As a means to assess the political and religious characteristics of these “unclassified” respondents, we compare non-denominationals to a prototypical evangelical denomination—the Southern Baptist Convention and a prototypical mainline denomination—the United Methodist Church using General Social Survey data from 2000 to 2018. We also re-run models of social and political phenomena, originally shown by Steensland et al. (Soc Forces 79:291, 2000), with the new and old RELTRAD categories. Results Analyses indicate that non-denominational Protestants who attend church at least once a month have similar characteristics to evangelicals, justifying their current classification. However, non-denominationals who attend less frequently are more difficult to sort cleanly as they are more conservative than United Methodists but more liberal than Southern Baptists. However, the gaps caused by attendance among the three groups is comparable, undermining the RELTRAD assumption that low attending non-denominationals should be excluded from the sample. Conclusions and Implications We reject the decision to exclude low attending non-denominationals from samples. Combined with other analyses of non-denominational Christians that show differences by denominationalism, we conclude that the best way forward may be creating an entirely new RELTRAD category for non-denominational Protestants that would solve the problem of the unclassifieds and not lose measure specificity. This choice brings new questions into focus as researchers can acknowledge the rapidly growing non-denominational category and assess the degrees of overlap and distinction with traditional religious families in the United States.

Abstract
Purpose
SARS-COV-2 infection can develop into a multi-organ disease. Although pathophysiological mechanisms of COVID-19-associated myocardial injury have been studied throughout the pandemic course in 2019, its morphological characterisation is still unclear. With this study, we aimed to characterise echocardiographic patterns of ventricular function in patients with COVID-19-associated myocardial injury.

Methods
We prospectively assessed 32 patients hospitalised with COVID-19 and presence or absence of elevated high sensitive troponin T (hsTNT+ vs. hsTNT-) by comprehensive three-dimensional (3D) and strain echocardiography.

Results
A minority (34.3%) of patients had normal ventricular function, whereas 65.7% had left and/or right ventricular dysfunction defined by impaired left and/or right ventricular ejection fraction and strain measurements. Concomitant biventricular dysfunction was common in hsTNT+ patients. We observed impaired left ventricular (LV) global longitudinal strain (GLS) in patients with myocardial injury (-13.9% vs. -17.7% for hsTNT+ vs. hsTNT-, p = 0.005) but preserved LV ejection fraction (52% vs. 59%, p = 0.074). Further, in these patients, right ventricular (RV) systolic function was impaired with lower RV ejection fraction (40% vs. 49%, p = 0.001) and reduced RV free wall strain (-18.5% vs. -28.3%, p = 0.003). Myocardial dysfunction partially recovered in hsTNT + patients after 52 days of follow-up. In particular, LV-GLS and RV-FWS significantly improved from baseline to follow-up (LV-GLS: -13.9% to -16.5%, p = 0.013; RV-FWS: -18.5% to -22.3%, p = 0.037).

Conclusion
In patients with COVID-19-associated myocardial injury, comprehensive 3D and strain echocardiography revealed LV dysfunction by GLS and RV dysfunction, which partially resolved at 2-month follow-up.

Risk Factors for Contra-Lateral Secondary Anterior Cruciate Ligament Injury: A Systematic Review with Meta-Analysis
Authors: Cronström Anna , Tengman Eva , Häger Charlotte K. 
Published: January 2021

Abstract
Background
The risk of sustaining a contra-lateral anterior cruciate ligament (C-ACL) injury after primary unilateral ACL injury is high. C-ACL injury often contributes to a further decline in function and quality of life, including failure to return to sport. There is, however, very limited knowledge about which risk factors that contribute to C-ACL injury.

Objective
To systematically review instrinsic risk factors for sustaining a C-ACL injury.

Methods
A systematic review with meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Four databases (MEDLINE, CINAHL, EMBASE, Sport Discus) were searched from inception to January 2020. Inclusion criteria were prospective or retrospective studies investigating any intrinsic risk factor for future C-ACL injury. Meta-analysis was performed and expressed as odds ratios (OR) if two or more articles assessed the same risk factor.

Results
44 moderate-to-high quality studies were eventually included in this review, whereof 35 studies were eligible for meta-analysis, including up to 59 000 individuals. We identified seven factors independently increasing the odds of sustaining a C-ACL injury (in order of highest to lowest OR): (1) returning to a high activity level (OR 3.26, 95% CI 2.10–5.06); (2) Body Mass Index < 25 (OR 2.73, 95% CI 1.73–4.36); (3) age ≤ 18 years (OR 2.42, 95% CI 1.51–3.88); (4) family history of ACL injury (OR 2.07, 95% CI 1.54–2.80); (5) primary ACL reconstruction performed ≤ 3 months post injury (OR 1.65, 95% CI: 1.32–2.06); (6) female sex (OR 1.35, 95% CI 1.14–1.61); and (7) concomitant meniscal injury (OR 1.21, 95% CI 1.03–1.42). The following two factors were associated with decreased odds of a subsequent C-ACL injury: 1) decreased intercondylar notch width/width of the distal femur ratio (OR 0.43, 95% CI 0.25–0.69) and 2) concomitant cartilage injury (OR 0.83, 95% CI 0.69–1.00). There were no associations between the odds of sustaining a C-ACL injury and smoking status, pre-injury activity level, playing soccer compared to other sports or timing of return to sport. No studies of neuromuscular function in relation to risk of C-ACL injury were eligible for meta-analysis according to our criteria.

Conclusion
This review provides evidence that demographic factors such as female sex, young age (≤ 18 years) and family history of ACL injury, as well as early reconstruction and returning to a high activity level increase the risk of C-ACL injury. Given the lack of studies related to neuromuscular factors that may be modifiable by training, future studies are warranted that investigate the possible role of factors such as dynamic knee stability and alignment, muscle activation and/or strength and proprioception as well as sport-specific training prior to return-to-sport for C-ACL injuries.

Published: January 2021

AbstractChaotic phenomena are observed in several practical and scientific fields; however, the chaos is harmful to systems as they can lead them to be unstable. Consequently, the purpose of this study is to analyze the bifurcation of permanent magnet direct current (PMDC) motor and develop a controller that can suppress chaotic behavior resulted from parameter variation such as the loading effect. The nonlinear behaviors of PMDC motors were investigated by time-domain waveform, phase portrait, and Floquet theory. By varying the load torque, a period-doubling bifurcation appeared which in turn led to chaotic behavior in the system. So, a fuzzy logic controller and developing the Floquet theory techniques are applied to eliminate the bifurcation and the chaos effects. The controller is used to enhance the performance of the system by getting a faster response without overshoot or oscillation, moreover, tends to reduce the steady-state error while maintaining its stability. The simulation results emphasize that fuzzy control provides better performance than that obtained from the other controller.

AbstractCystic fibrosis (CF) is a genetic autosomal recessive disease that involves multiple systems. Both life quality and expectation are affected by the debilitating multi-system involvement of the disease which includes pulmonary, gastrointestinal, reproductive, and endocrine symptoms. Very few studies have covered the epidemiological aspects of the disease among Arab countries. To systematically review the available epidemiological literature on cystic fibrosis in order to describe the epidemiological state of this disease in the Arab world, this review used PubMed to search for relevant articles related to patients with cystic fibrosis, with no restriction on gender or age. Google scholar and the snowballing technique were used to locate further articles. A total of 17 articles met the inclusion criteria for this review. These articles were from Bahrain, Egypt, Jordan, Kuwait, Morocco, Oman, Saudi Arabia, Tunisia, and the United Arab Emirates. The articles scored 1.5–6.5 out of 8 on the quality assessment. The epidemiological data reported varied based on country and type of study. The establishment of CF registries is definitely a priority in the region, as well as the need for more research involving CF patients particularly those involving the epidemiological and clinical characteristics of these patients.

AbstractPreeclampsia complicates 5–8% of all pregnancies worldwide, and although its pathophysiology remains obscure, placental oxidative stress and mitochondrial abnormalities are considered to play a key role. Mitochondrial abnormalities in preeclamptic placentae have been described, but the extent to which mitochondrial content and the molecular pathways controlling this (mitochondrial biogenesis and mitophagy) are affected in preeclamptic placentae is unknown. Therefore, in preeclamptic (n = 12) and control (n = 11) placentae, we comprehensively assessed multiple indices of placental antioxidant status, mitochondrial content, mitochondrial biogenesis, mitophagy, and mitochondrial fusion and fission. In addition, we also explored gene expression profiles related to inflammation and apoptosis. Preeclamptic placentae were characterized by higher levels of oxidized glutathione, a higher total antioxidant capacity, and higher mRNA levels of the mitochondrial-located antioxidant enzyme manganese-dependent superoxide dismutase 2 compared to controls. Furthermore, mitochondrial content was significantly lower in preeclamptic placentae, which was accompanied by an increased abundance of key constituents of glycolysis. Moreover, mRNA and protein levels of key molecules involved in the regulation of mitochondrial biogenesis were lower in preeclamptic placentae, while the abundance of constituents of the mitophagy, autophagy, and mitochondrial fission machinery was higher compared to controls. In addition, we found evidence for activation of apoptosis and inflammation in preeclamptic placentae. This study is the first to comprehensively demonstrate abnormalities at the level of the mitochondrion and the molecular pathways controlling mitochondrial content/function in preeclamptic placentae. These aberrations may well contribute to the pathophysiology of preeclampsia by upregulating placental inflammation, oxidative stress, and apoptosis.
The Role of Sexual Desire, Sexual Satisfaction, and Relationship Satisfaction in the Sexual Function of Arab Couples Living in Saudi Arabia
Authors: Attaky Atia , Schepers Jan , Kok Gerjo , Dewitte Marieke 
Published: January 2021

Abstract

Introduction
This study is one of the first to examine the association between relationship and sexual variables as approached from a dyadic perspective in Saudi Arabian couples. Theoretical models assign an important role to relationship factors in women's sexuality.

Aim
We examined the role of sexual and relationship satisfaction relative to sexual desire in explaining sexual function in a sample of clinical versus nonclinical couples.

Methods
This is a cross-sectional, observational study in a sample of 50 heterosexual couples with sexual problems and 50 control couples without problems (N = 100 couples; 200 men and women).

Main Outcome Measure
All participants completed an Arabic version of measures of relationship satisfaction, sexual satisfaction, sexual desire, sexual distress, and sexual function.

Results
Results showed that in the clinical group, sexual function of women was predicted by their own and their partner's level of sexual satisfaction, and their own level of solitary and dyadic sexual desire. Men's sexual function was predicted by their own sexual satisfaction and their partner's relationship satisfaction. In the control group, the sexual function of women was predicted only by their level of sexual satisfaction. In men, sexual function was predicted by their own sexual satisfaction and their level of dyadic sexual desire.

Conclusion
These results suggest that sexual desire rather than relationship satisfaction plays an important role in women's sexual dysfunction. Being the most consistent determinant of male and female sexual functioning, sexual satisfaction is an important target of intervention in Arabian couples.
TWO-VARIABLE LOGIC HAS WEAK, BUT NOT STRONG, BETH DEFINABILITY

AbstractWe prove that the two-variable fragment of first-order logic has the weak Beth definability property. This makes the two-variable fragment a natural logic separating the weak and the strong Beth properties since it does not have the strong Beth definability property.
Conservation status and biology of the Ultramarine Lorikeet Vini ultramarina in the Marquesas Islands, French Polynesia
Authors: DOUKAS TAMMY , ZIEMBICKI MARK 
Published: February 2021

SummaryClassified as Critically Endangered, the Ultramarine Lorikeet Vini ultramarina is one of the world’s most threatened lorikeet species. Endemic to the Marquesas Islands in French Polynesia, the species was formerly distributed over most islands in the archipelago, but is today found primarily on the island of Ua Huka, its range having contracted significantly in recent decades. Habitat alteration and loss, and over-exploitation of natural resources, are cited as impacting the Ultramarine Lorikeet, but the influence of introduced black rats Rattus rattus as predators has been implicated as the primary threat to the species. To assess population status and document aspects of the species biology, including habitat preferences and diet, we conducted the first systematic surveys of the species during two independent surveys spaced seven years apart (2002 and 2009). Population estimates of 2,011 ± 284 (in 2002) and 1,922 (in 2009) individuals on Ua Huka suggest the population was relatively healthy and stable between these periods. However, surveys and searches of other islands in the species’ contemporary range, where black rats occur, either failed to document the species or noted very few individuals. These findings highlight the critical importance of Ua Huka as a rat-free refuge and the value of our surveys as baseline estimates of the population status of the species. We discuss the conservation implications of our findings and propose recommendations to secure the species’ future survival.
Improving Facilitation of Student Communication Through Observational Feedback Within a Partner Instruction Model
Authors: Hayes Laura E. , Traughber Matthew C. 
Published: January 2021

Purpose
The purpose of this study was to further evaluate an eight-step partner instructional model developed by Kent-Walsh and McNaughton that has been demonstrated to improve implementation quality and fidelity among adults in clinical and educational settings who support the use of augmentative and alternative communication (AAC) for individuals with complex communication needs.

Method
This study examined the effectiveness of the eight-step model in a K–12 special education setting. Participants included 26 staff and 19 students. Effects on both communication partner modeling and student AAC system use were assessed. The study expanded upon prior research by employing a group design, including largely adolescent participants, and utilizing multiple AAC hardware and software types.

Results
Staff receiving training and coaching via the full eight-step model demonstrated gains in the percentage of utterances modeled, and their student partners increased mean length of utterance. The study failed to find statistically significant differences between the experimental group and a comparison group receiving only Stages 1–5 of the model.

Conclusion
Findings provide additional evidence for the viability of the eight-step instructional model as a methodology to promote the communication skills of students who utilize AAC, and also point to the advanced practice and feedback element of the model as a potential mediator of intervention outcomes.
Leveling Up Regulatory Support Through Community Collaboration
Authors: Laurent Amy C. , Fede Jacquelyn 
Published: January 2021

Purpose
No group has more stake in the game than the community that researchers, educators, and practitioners aim to serve. In our field, we must recognize not only that autistic people are those most affected by decisions around programming and policies, but that they are key informants in decisions around the conceptualization, implementation, and evaluation of educational programming for autistic learners. Too often, they are left out of these discussions altogether. To illustrate the process of community collaboration, we discuss emotional and energy regulation (ER), a top priority among autistic people based upon their viewpoints.

Method
In this clinical focus article, we outline what emotional regulation is, why it is relevant and often challenging for the autistic population, the shortcomings of current practice, as well as practical strategies and ways of thinking about supporting ER for autistic learners. We provide theoretical insights as well as firsthand accounts from a diverse group of autistic people. Each autistic person contributing their perspective in this clinical focus article provided written consent for their participation, as well as direction as to how they wanted to be cited and acknowledged. Quotes were gathered from personal communications, social media posts, and online sources. The clinical viewpoint and materials and tools presented throughout the clinical focus article are the works of the authors that have been informed by the autistic community.

Results
Based upon the qualitative data presented in this clinical focus article, incorporating the autistic community voice when devising tools and strategies is validating of their experiences and generates useful supports.

Conclusions
Using a framework similar to the one presented here for engaging the autistic community will help to facilitate the conceptualization of more reliable, valid, and effective supports, goal-setting, and programming overall. Future directions related to the value of empirical study of the tools and strategies developed through such a process are offered.
