Authors: Priyadarshini Aishwarya , Mishra Sanhita , Mishra Debani Prasad , Salkuti Surender Reddy , Mohanty Ramakanta
Published: September 2021

Nowadays, fraudulent or deceitful activities associated with financial transactions, predominantly using credit cards have been increasing at an alarming rate and are one of the most prevalent activities in finance industries, corporate companies, and other government organizations. It is therefore essential to incorporate a fraud detection system that mainly consists of intelligent fraud detection techniques to keep in view the consumer and clients’ welfare alike. Numerous fraud detection procedures, techniques, and systems in literature have been implemented by employing a myriad of intelligent techniques including algorithms and frameworks to detect fraudulent and deceitful transactions. This paper initially analyses the data through exploratory data analysis and then proposes various classification models that are implemented using intelligent soft computing techniques to predictively classify fraudulent credit card transactions. Classification algorithms such as K-Nearest neighbor (K-NN), decision tree, random forest (RF), and logistic regression (LR) have been implemented to critically evaluate their performances. The proposed model is computationally efficient, light-weight and can be used for credit card fraudulent transaction detection with better accuracy.

Published: September 2021

Water quality plays a major role in issues related to public health and marine life. Hence, monitoring river for contaminations is vital for ensuring safe and sustainable water resources. Conventional method for assessing water quality index is costly as it requires considerable amount of time and laboratory resources. Therefore, this study proposes a water quality index model based on artificial neural network. A six-year data for Air Busuk River is obtained from the Department of Environment. Dissolved oxygen, biological oxygen demand, and ammoniacal nitrogen has shown high correlation with water quality index. The water quality index model is then developed based on these parameters, employing the non-linear autoregressive with exogeneous input structure. Generally, the model which is based on three chemical parameters has shown satisfactory performance with overall regression of 0.8767 and passed the correlation function tests. The model offers a potentially efficient method for assessing water quality with cost-saving benefits for government agencies and monitoring authorities.

Authors: Flauzino Rodrigo Humberto , Peres Cristiane Martins , Carmona Fábio
Published: September 2021

O processo educativo vivenciado por estudantes e professores deve ser focado na aquisição de conhecimento, habilidades e atitudes relevantes para compreensão dos fenômenos da vida e sua aplicação na prática profissional, exigindo a participação ativa e efetiva dos muitos envolvidos: estudantes, professores, gestores acadêmicos e outros atores importantes. Ainda que essa máxima faça parte dos discursos dos cursos da área da saúde, ressalta-se, neste trabalho, o valor fundamental do planejamento para uma ação educacional de qualidade. A adoção de instrumentos pedagógicos próprios para este fim pode favorecer uma melhor reflexão, desenvolvimento e comunicação do percurso de formação dos estudantes. Na Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo (FMRP-USP), o instrumento utilizado é conhecido como Plano de Ensino e Aprendizagem, o PEA. Neste relato de experiência, apresenta-se o seu contexto de implementação, as discussões envolvendo a comunidade acadêmica, as ações formativas para torná-lo um recurso vivo e potente para o fazer docente, elementos estes que fortaleceram o ensino nos cursos de graduação da FMRP. Ao longo deste artigo, o leitor conhecerá as partes que compõem o PEA, orientações sobre como elaborá-lo, exemplos produzidos por professores e um conjunto de rubricas e critérios que contribuem para nortear o planejamento no contexto da docência nas profissões da saúde.
Ensino Remoto em tempos de pandemia: a experiência da Pontifícia Universidade Católica de São Paulo (PUC-SP)
Authors: Mello Julia Brum de , Sampaio Neto Luiz Ferraz , Geraldini Alexandra Fogli Serpa , Cesaretti Mário Luís Ribeiro
Published: September 2021

A Pontifícia Universidade Católica de São Paulo é uma universidade comunitária. Em março de 2020, o distanciamento/isolamento social ocasionado pela pandemia da SARS-CoV-2 impôs diversos desafios a serem enfrentados, relacionados à migração do ensino presencial para o ensino remoto/ capacitação tecnológica (e pedagógica) do corpo docente, suporte aos estudantes, capacitação tecnológica do corpo funcional e adequação da infraestrutura de tecnologia da informação. Neste trabalho trataremos da capacitação docente. Embora não existisse uma estrutura de desenvolvimento docente institucionalizada, um grupo de docentes envolvidos nas diversas capacitações que vinham sendo promovidas desde 2017 pela instituição, por iniciativa da Pró-Reitoria de Graduação, foi responsável pela capacitação do conjunto de docentes da Universidade para uso das plataformas institucionais. Também foram criados treinamentos individuais para atender às necessidades dos docentes. Superada a primeira fase de familiarização com as plataformas, a etapa seguinte foi suscitar, no corpo docente, a necessidade de qualificação das atividades remotas, por meio do uso de metodologias inovadoras de ensino. A necessidade de manutenção do ensino remoto levou à ampliação do grupo de docentes responsáveis pelo apoio às atividades remotas. Mais ainda, monitores pós-graduandos (mestrandos e doutorandos) dos diferentes cursos da universidade foram selecionados para auxiliar os docentes, de forma individualizada, para que fizessem o uso apropriado de estratégias de ensino e as plataformas tecnológicas. No curso de Medicina da PUC-SP, que tem em seu cerne o uso de estratégias ativas de ensino e aprendizagem, com exceção de parte das atividades práticas, todas foram realizadas remotamente. A adaptação das tutorias da aprendizagem baseada em problemas foi satisfatória. Um dos aprendizados mais significativos foi o trabalho colaborativo docente para a realização de avaliações somativas.

Deontology, Consequentialism and Reciprocity in Contemporary Just War Thinking
Authors: Brown Chris
Published: September 2021

There has always been a degree of tension between, on the one hand, the writings of philosophers, theologians and lawyers on the ethics of war, and, on the other, the moral approach of soldiers, those actually engaged in combat. The former base their thinking on deontological reasoning, albeit with occasional reluctant gestures towards notions such as ‘military necessity’, while the latter are by temperament consequentialist, stressing, in particular, the importance of reciprocity. This tension is controllable in the implausible context of war between liberal, Western European countries, but comes to the surface in situations where regular Western armies are in combat with the armed forces of non-liberal states, or in situations of asymmetric warfare. The question is posed – can the notion of a just war survive in the absence of reciprocity?
Tertullian and penal substitutionary atonement
Authors: Ensor Peter
Published: September 2021

This article argues that the writings of Tertullian imply that Christ’s atoning death on the cross was a work of penal substitution. Having noted the importance of the cross in Tertullian’s thought, the contexts in which references to the cross are found in his writings, and the salvific effects which he attributes to the cross, the article examines some specific passages which are most naturally understood to imply a penal substitutionary understanding of the significance of the cross. The article therefore strengthens the view, already held on the grounds of similar studies of the atonement teaching of Justin Martyr and Clement of Alexandria, that the penal substitutionary understanding of the atoning work of Christ on the cross was widely held in the post-apostolic Church.
Taraxacum assemanii represents a new section: A revision of the misinterpreted Taraxacum primigenium, and the elucidation of the enigmatic Taraxacum section Primigenia (Compositae, Crepidinae)
Authors: KIRSCHNER JAN , ŠTĚPÁNEK JAN , DOOSTMOHAMMADI MOSLEM , ZEISEK VOJTĚCH
Published: September 2021

On the basis of new gatherings at the type locality, Taraxacum primigenium was evaluated taxonomically. Its achenes differ substantially from the protologue description that is based on achenes of T. assemanii. Taraxacum primigenium, also on the basis of an nrDNA analysis, is close to T. sect. Piesis, and represents a narrow endemic confined to the Lalezar Mts., SE Iran. Taraxacum assemanii, newly typified, is known from mountains of SE Anatolia and Lebanon, and from the Zagros in SW Iran. It is characterized by large, almost or totally smooth achenes with indistinct cone and a very gradual achene body/beak transition, a thick short beak and a short, slightly brownish pappus. It represents a single member of a newly described section, T. sect. Pristina. The name of T. sect. Primigenia, although with a diagnosis corresponding to the characters of T. assemanii, is to be interpreted according to its type, T. primigenium, and is understood as a synonym of T. sect. Piesis. Another taxon evaluated, T. cylleneum, endemic to several mountain ranges in of Peloponnesos, Greece, is similar to T. primigenium, and very close to the core taxa of T. sect. Piesis. All the species dealt with reproduce sexually.

Authors: Wang Judy J. , Rubin Samuel J. , Devaiah Anand K. , Faden Daniel L. , Salama Andrew R. , Edwards Heather A.
Published: September 2021

Objective:

This study aims to identify clinical and socioeconomic factors associated with long-term, post-surgical opioid use in the head and neck cancer population.

Methods:

A single center retrospective study was conducted including patients diagnosed with head and neck cancer between January 1, 2014 and July 1, 2019 who underwent primary surgical management. The primary outcome measure was continued opioid use 6 months after treatment completion. Both demographic and cancer-related variables were recorded to determine what factors were associated with prolonged opioid use. Univariate analysis was performed using chi-squared test for categorical variables and 2-sample t-test for continuous variables. Multivariate analysis was performed using logistic regression.

Results:

A total of 359 patients received primary surgical management. Forty-five patients (12.53%) continued to take opioids 6 months after treatment completion. Using univariate analysis, patients less than 65 years of age ( P = .0126), adjuvant chemoradiation (n = 25, P < .001), and overall length of hospital stay (8.60 ± 8.58 days, P = .0274) were significantly associated with long term opioid use. Multivariate logistic regression showed that adjuvant chemoradiation (OR = 3.446, 95% CI [1.742, 6.820], P = .0004) and overall length of hospital stay (OR = 0.949, 95% CI [0.903, 0.997], P = .0373) to be significantly associated with opioid use 6 months after head and neck cancer treatment.

Conclusion:

Long-term postoperative opioid use in head and neck cancer patients is significantly associated with adjuvant chemoradiation, and patients with longer length of hospital stay. Therefore, future research should focus on interventions to better manage opioid use during the acute treatment period to decrease long-term use.
Firearm-Related Homicide in Sweden: A Latent Class Analysis of Suspected Offenders
Authors: Khoshnood Ardavan , Ohlsson Henrik , Sundquist Jan , Sundquist Kristina
Published: September 2021

Sweden has witnessed a significant increase in the rate of firearm-related homicide. We therefore aimed to study the characteristics of individuals suspected of homicide, attempted homicide, preparation to commit homicide as well as conspiracy to commit homicide with a firearm in Sweden. By using information from different registers, suspected individuals between 2000 and 2017 and aged 15 to 60 were included in the study. A total of 889 individuals were evaluated. A notable part were females (5.1%). Latent Class Analysis identified three classes, where two classes were high-offending-classes, and one class was a low-offending-class. The identification of these classes may be used for more effective preventive measures.
Global Production System, Textile Industry and Wage Disparity: Evidence from South India
Authors: Ramamurthy Nandini
Published: September 2021

This article discusses the root causes of wage disparity in the textile industry. The study argues that wage disparity arises through direct and indirect approaches. Both create pressure on suppliers and leads to low wage payment, depriving workers of social security benefits, unpaid holidays and leaves. Hyper-consumerism, free on board (FoB) price, and flexibility have created competition among suppliers and other stakeholders. Suppliers flexibilise rules and re-organise work arrangements to meet on-time production by increasing working hours, introducing wage penalty, strict supervising, and increasing surveillance.

The Australian Reifungsroman: Reading women’s ageing in Kate Grenville’s The Idea of Perfection and Dorothy Hewett’s Neap Tide
Authors: Liu Yuanhang
Published: September 2021

Women’s ageing processes raise important questions about the relationship between the body, the self, and society, but this topic has been widely ignored in Australian literature. The Australian Reifungsroman, through nuanced articulations of ageing women’s experiences of being doubly othered, shows itself to be a critical discourse that helps to break the cultural silence accorded to ageing women. This article aims to acknowledge the existence of the Reifungsroman in Australian literature while addressing questions around how this genre is employed in the Australian context, in order to actively engage with the topic of women’s ageing. Drawing on literary gerontology, this article examines Australian novelist Kate Grenville’s The Idea of Perfection (2000) and Dorothy Hewett’s Neap Tide (1999) from a feminist perspective, focusing on the literary representations of ageing women offered by these novels. In so doing, this article contends that the Australian Reifungsroman unsettles the dominant ideas about women’s ageing as negative and declining. Indeed, narratives such as these help to articulate ageing women’s agency by reconstructing new images of older womanhood.
“Let the little children come”: Liturgical Revision and Paedocommunion in the Christian Reformed Church
Authors: Faber Ryan L.
Published: September 2021

This article examines the Lord’s Supper liturgies of the Christian Reformed Church in North America (CRC) and inquires into a possible relationship between liturgical changes and the admission of children to the Lord’s Supper. The stern warnings and emphasis on communicants’ understanding of the sacrament in the CRC’s oldest liturgies necessarily excluded children from participating in the sacrament. The 1968 Order for Communion was a milestone in the denomination’s liturgical growth. The absence of a preparatory exhortation and lengthy exposition provide a liturgy which can imagine children participating in the Lord’s Supper. An increasing emphasis on communicants’ communion with one another, evident in the 1981 Service of Word and Sacrament and the formularies adopted by Synods 1994 and 2016 may have helped facilitate the denomination’s acceptance of paedocommunion.
New Frontiers in American Evangelical Worship
Authors: Ross Melanie C.
Published: September 2021

This article puts Frederick Jackson Turner’s “frontier thesis”—an interpretation of American history that held sway among historians and the general public from the late 1890s to the 1930s—in conversation with James F. White’s depiction of an American liturgical “frontier tradition”—an interpretation of evangelical worship that became popular in the 1990s and continues to hold sway in the twenty-first century. It analyzes both through the lens of contemporary critiques and proposes new lines of inquiry that will contribute to a more robust understanding of American evangelical worship.
Recording as the Re-Membering Work of the People: A Catholic-Jewish Dialogue on the Body and Liturgical Memory
Authors: Belcher Kimberly H. , Grove Kevin G. , Pilz Sonja K.
Published: September 2021

The word leitourgia, meaning the work of the people, is often used to describe Christian worship and has also been adopted by many scholars of Jewish public worship. This word implies that liturgical worship in the Jewish and Christian traditions is a work that incorporates a people or assembly. The time- and place-shifting afforded by new recording technologies, however, alters the nature of liturgical work and its relationship to tradition, memory, and the assembly. In this article, phenomenology and reflexivity are deployed to examine the role of the body and its liturgical formation on producing and revisiting recorded liturgy. Liturgical work is already practiced by worshippers who (often in defiance of official leadership) record and view recorded liturgies. The embodied work of this displaced assembly reveals unexpected similarities in Jewish and Catholic ordained leaders’ “flattening” before the physical and metaphorical cameras of Western public life. Finally, diverse experiences of recorded liturgy are used to compare theological concepts of liturgical memory in Jewish and Catholic thought.
Multifunctional CeO2/Co3O4@polyacrylonitrile nanoﬁbers for high-efficiency air-pollutant removal
Authors: Wang Qi , Hu Tingting , Zhang Wenqi , Jiang Zhenlin , Rao Pinhua
Published: September 2021

As many countries in the world are paying increasing attention to air quality, reducing the concentration of pollutants in the air, protecting human health and improving the ecological environment have become problems that need to be solved urgently. This paper describes how ceria and cobalt tetroxide@polyacrylonitrile (CeO2/Co3O4@PAN) nanofiber membranes are produced using electrospinning technology, which have broad applications for the removal of air pollutants. Results show that CeO2/Co3O4@PAN has high electrostatic attraction to particulate matter (PM). CeO2/Co3O4@PAN membranes show better mechanical properties, thermal stability and air-purification performance than pure PAN membranes. Nanofiber membranes with 5 wt% of CeO2/Co3O4 have excellent removal efficiency: 93.4% and 94.5% for PM2.5 and PM10, respectively, and 96.2% and 98% for formaldehyde and total volatile organic compounds, respectively. They also show low pressure drops, high stability and good recyclability. This work shows that they are promising candidates as highly stable, recyclable and efficient agents for the removal of air pollutants.
Wait-there’s evidence for that? Integrative medicine treatments for major depressive disorder
Authors: Warnick Stephen J , Mehdi Laraib , Kowalkowski Jennifer
Published: September 2021

Depression is one of the most common mental health disorders and currently affects over 17 million Americans. Up to two-thirds of patients with depression in the United States will seek complementary and alternative or integrative medical treatments and thus medical providers who treat depression should understand that many integrative medical treatments have evidence of efficacy either as monotherapies or as add-on adjuncts to other treatments. This review references guidelines from the Canadian Network for Mood and Anxiety Treatments and Michigan Medicine, along with an updated literature review, to provide a framework for reviewing medications or herbal formulation, as well as other therapies, which have evidence in the treatment of depression. In general, St. John’s Wort, Omega-3 Fatty Acids, S-adenosyl-L-methionine, and crocus sativus (saffron) have the highest levels of evidence in the treatment of mild-to-moderate depression. Acetyl-l-carnitine, l-methylfolate, DHEA, and lavender have a moderate level of evidence in treating depression, whereas Vitamin D, one of the most common supplements in the United States, does not have evidence in treating depression. Of the non-medication-based therapies, exercise, light therapy, yoga, acupuncture, and probiotics have evidence in the treatment of depression, whereas a full review of dietary modifications for depression was out of scope for this article.
Perceived Procedural Justice Enhances Correctional Officers’ Organizational Citizenship Behavior: Correlational and Causal Evidence From Israel
Authors: Nelson Noa , Appel Orit
Published: September 2021

Procedural justice refers to unbiased, caring, respectful, and participative treatment by decision makers. It positively associates with employees’ citizenship behavior, an expression of motivation and commitment that consists of voluntary helpful acts toward the organization or fellow employees. In view of scarce research on these variables in correctional facilities, we conducted two studies among Israeli correctional officers. In a survey ( N = 336), procedural justice by the commander moderately associated with organization- and individual-targeted citizenship behavior. In addition, commander procedural justice predicted perceiving organization procedural justice, which in turn strongly associated with organization-targeted citizenship. In an experiment ( N = 311), commander procedural justice enhanced organization- but not individual-targeted citizenship behavior. These studies provide new statistical and causal evidence for procedural justice effects on correctional officers, which can inform prison administrations’ practices. They also generalize justice effects to the Israeli prison culture and provide knowledge on Israeli officers, hitherto notably understudied.
Predicting Organizational Mortality: How Financial Management Matters
Authors: Park Young Joo , Shon Jongmin , Lu Jiahuan
Published: September 2021

Managing financial resources is one of the most important responsibilities of every organization; however, the literature still cannot provide an answer to an important question: how does financial health matter to organizational mortality, especially for nonprofit organizations? To advance our knowledge in this regard, this study empirically examines the effects of solvency, profitability, margin, and liquidity on nonprofit dissolution. Higher solvency, profitability, and margin have significant effects on reducing the likelihood of nonprofit dissolution, but liquidity does not function as a significant predictor.
bmggum: An R Package for Bayesian Estimation of the Multidimensional Generalized Graded Unfolding Model With Covariates
Authors: Tu Naidan , Zhang Bo , Angrave Lawrence , Sun Tianjun
Published: September 2021

Over the past couple of decades, there has been an increasing interest in adopting ideal point models to represent noncognitive constructs, as they have been demonstrated to better measure typical behaviors than traditional dominance models do. The generalized graded unfolding model ( GGUM) has consistently been the most popular ideal point model among researchers and practitioners. However, the GGUM2004 software and the later developed GGUM package in R can only handle unidimensional models despite the fact that many noncognitive constructs are multidimensional in nature. In addition, GGUM2004 and the GGUM package often yield unreasonable estimates of item parameters and standard errors. To address these issues, we developed the new open-source bmggum R package that is capable of estimating both unidimensional and multidimensional GGUM using a fully Bayesian approach, with supporting capabilities of stabilizing parameterization, incorporating person covariates, estimating constrained models, providing fit diagnostics, producing convergence metrics, and effectively handling missing data.
A New Method to Balance Measurement Accuracy and Attribute Coverage in Cognitive Diagnostic Computerized Adaptive Testing
Authors: Sun Xiaojian , Andersson Björn , Xin Tao
Published: September 2021

As one of the important research areas of cognitive diagnosis assessment, cognitive diagnostic computerized adaptive testing (CD-CAT) has received much attention in recent years. Measurement accuracy is the major theme in CD-CAT, and both the item selection method and the attribute coverage have a crucial effect on measurement accuracy. A new attribute coverage index, the ratio of test length to the number of attributes (RTA), is introduced in the current study. RTA is appropriate when the item pool comprises many items that measure multiple attributes where it can both produce acceptable measurement accuracy and balance the attribute coverage. With simulations, the new index is compared to the original item selection method (ORI) and the attribute balance index (ABI), which have been proposed in previous studies. The results show that (1) the RTA method produces comparable measurement accuracy to the ORI method under most item selection methods; (2) the RTA method produces higher measurement accuracy than the ABI method for most item selection methods, with the exception of the mutual information item selection method; (3) the RTA method prefers items that measure multiple attributes, compared to the ORI and ABI methods, while the ABI prefers items that measure a single attribute; and (4) the RTA method performs better than the ORI method with respect to attribute coverage, while it performs worse than the ABI with long tests.
Pregnant Black Women and Emergency Department Utilization: Assessing Self-Reported Receipt of Prenatal Counseling
Authors: Ismailova Inara , Yagihashi Emily , Saadat Nadia , Misra Dawn
Published: September 2021

There is limited literature on emergency department (ED) use among pregnant women. In this article, we examined the associations between prenatal counseling with the use of the ED during pregnancy. In our cohort of Black women in the Metro Detroit area, we found that approximately 70.5% of the women had an ED visit at some point during pregnancy. In unadjusted models of prevalence ratios, we found women reporting receipt of prenatal counseling regarding fetal movement, what to do about baby’s movement slowing down, and smoking (but not what to do about smoking) were at statistically significantly greater risk of ED utilization during pregnancy. Adjustment for confounders slightly weakened the associations for counseling about baby’s movement or smoking, so that the associations were no longer statistically significant. These findings call for further research on ED utilization among this population, especially differentiating urgent versus non-urgent use of the ED during pregnancy.

Published: September 2021

Aneurysms of descending thoracic aorta following surgical repair of coarctation have been reported in literature. Almost always, they are seen in repairs involving prosthetic patch aortoplasty. We report a neonate who underwent resection and an extended end to end anastomosis repair of coarctation and subsequently developed a huge pseudoaneurysm at a 3-month follow-up. He underwent a repair of the same through a sternotomy approach under hypothermic low flow cardiopulmonary bypass. An autologous pericardial patch aortoplasty was done successfully.
Post-Neoliberalism? An Introduction
Authors: Davies William , Gane Nicholas
Published: September 2021

This article provides an introduction to the special issue on post-neoliberalism. It does so by considering challenges to the neoliberal order that have come, post-financial crisis, from the political right. It looks closely at the relation of neoliberalism to conservatism, on one hand, and libertarianism, on the other, in order to address the threat posed to the neoliberal order by paleoconservatism, neoreactionary politics, ordonationalism, libertarian paternalism, and different forms of sovereignty and elite power. The final section of this introduction reflects on the challenge to the neoliberal orthodoxy posed by the current COVID-19 crisis. For while events of 2020–21 have facilitated new forms of privatization of many public services and goods, they also signal, potentially, a break from the neoliberal orthodoxies of the previous four decades, and, in particular, from their overriding concern for the market.
Monocyte to high density lipoprotein ratio in patients with acute kidney injury after cardiac surgery
Authors: Huang Wenjuan , Wang Lei , Wan Xin
Published: September 2021

Background:

The Monocyte to high density lipoprotein ratio (MHR) has been postulated as a novel parameter associated with adverse renal and cardiovascular outcomes. In this study we investigated the association of MHR with cardiac surgery-associated acute kidney injury (CSA-AKI).

Methods:

In this retrospective study, we analyzed the data pertaining to 1505 patients undergoing cardiopulmonary bypass (CPB) surgery. The CSA-AKI, which was defined using Kidney Disease Improving Global Outcomes criteria. Concurrently, a retrospective scan of patient files was conducted and information relevant to nephropathy such as the level of their serum creatinine (SCr), Blood urea nitrogen (BUN), uric acid (UA), serum cystatin C (Cys-C), total cholesterol (TC), triglycerides (TG), glucose and MHR, ejection fraction, CPB duration time, and other indicators.

Results:

About 1505 patients were studied of whom 195 developed AKI. MHR was significantly higher in the AKI patients (p = 0.001). In multivariate logistic regression analysis, MHR, UA, Cys-C, age, glucose, and history of chronic kidney disease or hypertension were independently correlated with CSA-AKI.

Conclusions:

As a laboratory index, the elevated MHR is convenient, independent, and a useful predictor for CSA-AKI.

Published: September 2021

Objective

To analyse the epidemiological data on suicide in French Polynesia (FP).

Methods

Data on suicides were collected from the Public Health Direction, Judicial Police Investigations Court of Justice records, the Centre d’Opérations et de Renseignements de la Gendarmerie, patient records for those hospitalized in psychiatry and from psychological autopsies.

Results

The dataset consisted of 316 suicide cases in FP over 25 years (1992–2016). In FP, suicide was more frequent in men (sex ratio 3.2:1), young people (mean age, 34.4 years) and individuals with previously diagnosed psychiatric disorders (100 of 316; 31.6%) The most common method of suicide was hanging (276 of 316; 87.3%). A history of previous suicide attempts was found in 25 of 56 (44.6%) of suicide cases, when documented. The most common potential triggering factors for suicide were emotional problems. The suicide rates have remained stable during 1992–2016 (mean 10.6/100 000 inhabitants per year), with periods of economic crises increasing suicide rates.

Conclusions

These results provide valuable information to enable the effective targeting of suicide prevention strategies toward those at high risk. Economic crises had larger impacts in the French overseas territories than mainland France. Given the unprecedented economic impact of the Covid-19 pandemic in FP, there is an urgent need to implement suicide epidemiological surveillance and prevention programmes.

Published: September 2021

Background

Atogepant is an oral, small-molecule, calcitonin gene–related peptide receptor antagonist for the preventive treatment of migraine.

Methods

In the double-blind, phase 3 ADVANCE trial, participants with 4–14 migraine days/month were randomized to atogepant 10 mg, 30 mg, 60 mg, or placebo once daily for 12 weeks. We evaluated the time course of efficacy of atogepant for the preventive treatment of migraine. Analyses included change from baseline in mean monthly migraine days during each of the three 4-week treatment periods, change in weekly migraine days during weeks 1–4, and proportion of participants with a migraine on each day during the first week.

Results

We analyzed 873 participants (n = 214 atogepant 10 mg, n = 223 atogepant 30 mg, n = 222 atogepant 60 mg, n = 214 placebo). For weeks 1–4, mean change from baseline in mean monthly migraine days ranged from −3.1 to −3.9 across atogepant doses vs −1.6 for placebo ( p < 0.0001). For weeks 5–8 and 9–12, reductions in mean monthly migraine days ranged from −3.7 to −4.2 for atogepant vs −2.9 for placebo ( p ≤ 0.012) and −4.2 to −4.4 for atogepant vs −3.0 for placebo ( p < 0.0002), respectively. Mean change from baseline in weekly migraine days in week 1 ranged from −0.77 to −1.03 for atogepant vs −0.29 with placebo ( p < 0.0001). Percentages of participants reporting a migraine on post-dose day 1 ranged from 10.8% to 14.1% for atogepant vs 25.2% with placebo ( p ≤ 0.0071).

Conclusion

Atogepant demonstrated treatment benefits as early as the first full day after treatment initiation, and sustained efficacy across each 4-week interval during the 12-week treatment period. Clinical trial registration: ClinicalTrials.gov identifier: NCT03777059
Teaching Methods in Undergraduate Intermediate Theory, Statistics and Econometrics, and Other Upper-Division Economics Courses: Results From a Sixth National Quinquennial Survey
Authors: Harter Cynthia , Asarta Carlos J.
Published: September 2021

This article is an extension of a recent article published in The American Economist (Asarta et al., 2021) and presents the second report of basic findings from the 2020 online administration of the sixth national quinquennial survey on teaching and assessment methods in economics. Consistent with the results from the first report, we find that “chalk and talk” remains the staple method of instruction across the entire undergraduate economics curriculum. Lessons, activities, and references that address diversity, inclusion, or gender issues are almost never used in intermediate theory, statistics and econometrics, and other upper-division field courses. There has been notable growth in the use of cooperative learning/small-group assignments, as well as in instructor-led and “student(s) with student(s)” discussions over the past 25 years. Overall, however, there have been minimal changes in teaching methods over time.

Thanatopolitics and colonial logics in Blade Runner 2049
Authors: Taşkale Ali Rıza
Published: September 2021

This article critically engages with Denis Villeneuve’s Blade Runner 2049, focusing on the relationship between colonial logics and biological engineering that understands the natural world as property. First, it discusses the connections between the film and the shifting status of biopolitics becoming thanatopolitics, prompted by advances in synthetic biology. It argues that the film’s preoccupation with the reproductive capacity of its replicants retraces a racialized (post) colonialism and reconfigured slavery, or the voluntary labour of the occupied – as normalized in synthetic biology and the ongoing processes of devaluing of some lives over others for socioeconomic reasons. Second, and relatedly, the film reveals how deeply the thanatopolitics of a biopolitical economy is rooted in an intensification of racialized and colonial logics. The film thus doubles as a medium in which to grasp the centrality of colonial and racial logics to the ongoing real subsumption of life by capital, and the ways in which it continues to shape the present.
My Sister’s Keeper: Survivors Disclosing Sexual Violence to a Sibling
Authors: Barrios Veronica R. , Corpora Miranda , Pawlecki Emily , Caspi Jonathan
Published: September 2021

Siblings are often cited as a source of support throughout life, but they have not been included in studies of sexual violence disclosure. Survivors of sexual violence often delay or do not disclose their sexual violence. The current study investigated if and why survivors of sexual violence decided to disclose to their sibling. This qualitative investigation included 10 female participants, of which six had disclosed their abuse to their sibling. The participants ranged in age from 20 to 58, five identified as Hispanic, one as Hispanic and White three identified as White, and one identified as Middle Eastern. Thematic analysis was used to examine the data. Three major themes were identified that affected sibling disclosure decisions: sibling dynamics, perceived and real reactions to disclosure, and words of advice. The findings from this study demonstrate the continued need to investigate siblings and their role in disclosure of sexual violence. Practitioners may also want to examine the sibling relationship as a source of support for survivors of sexual violence. Finally, as policies continue to develop around support of survivors of sexual violence, inclusion of siblings in family policies, outreach centers, and counseling services may be beneficial.
Optimal adaptive race strategy for a Formula-E car
Authors: Anselma Pier Giuseppe
Published: September 2021

Appropriately managing battery state-of-charge and temperature while ensuring minimized lap time represents a crucial issue in Formula-E competitions. An open research question might relate to simultaneously guarantee near-optimality in the race strategy solution, computational light-weighting, and effective adaptability with respect to varying and unpredictable race conditions. In this paper, a novel near-optimal real-time capable Formula-E race controller is introduced that takes inspiration from the adaptive equivalent consumption minimization strategy (A-ECMS) approach. A reduced-order Formula-E car plant model is detailed first. The optimal Formula-E race problem subsequently discussed involves controlling at each lap the depletable battery energy, the thermal management mode, and the race mode in order to minimize the overall race time. Moreover, avoiding excessively depleting the battery energy and overheating the battery are considered as constraints for the race optimization problem. Dynamic programing (DP) is implemented first to obtain the global optimal Formula-E race strategy solution in an off-line control approach. The proposed real-time capable A-ECMS based race controller finds then detailed illustration. The flexibility of the introduced A-ECMS Formula-E race controller is guaranteed by optimally calibrating the related equivalence factors to adapt to the current vehicle states (i.e. battery state-of-charge, battery temperature, and lap number). Simulation results for the Marrakesh e-prix considering different race scenarios in terms of battery initial temperature and Safety car entry demonstrate that the estimated race time achieved by the A-ECMS race controller is always near-optimal being 1.7% higher at most compared with the corresponding global optimal benchmark provided by DP.
Experimental investigation of designed solar parabolic concentrator based desalination system for textile industry wastewater treatment

Published: September 2021

The escalation in demand for textile products increased the use of fresh water and treatment of wastewater; which escalates the search for suitable and energy-efficient technology for wastewater treatment. Solar assisted technology ( i.e. solar desalination) for the textile industry wastewater treatment is proved to be an affordable technology. The only drawback of solar desalination is its low productivity which is the major hindrance in the global acceptance of the system. In the present study, an ingenious improvement in form of a parabolic concentrator-based solar desalination system (PCB-SDS) is designed to overcome low productivity, and the simultaneous use of source textile industry wastewater for its treatment makes this study more realistic. The performance of the designed system was examined for three different brine depths i.e. 20%, 40%, and 60% for two different processing step i.e. Dyeing and Degumming. System performance was evaluated in terms of energetic, exergetic, pollutant removal, and economic analysis. The maximum output of the system was found to be around 7440 and 8330 mL/day on clear sunny days with textile dyeing wastewater (TDyWW) and textile degumming wastewater (TDgWW) at 60% depth respectively. Daily average energy and exergy efficiency of system varies in the range 39.8–51.9 and 3.6–4.8% respectively. The degumming wastewater shows 85% COD removal, whereas, around 90% of TDS and hardness removal was also recorded. The dyeing processed wastewater showed 80% COD removal efficiency, ≅90% TDS, and hardness removal. The cost per liter of distillate output produced from designed PCB-SDS was found to be 0.014 $/L.
Determinants of firm-level energy productivity – Evidence from the Korean emission trading scheme
Authors: Mo Jung Youn , Jeon Wooyoung
Published: September 2021

With increasing global pressure on transition to carbon neutrality, various technical and policy efforts such as emission trading scheme and carbon tax are being made to improve energy productivity. Yet, there are not many literatures that analyze determinants of firm-level energy productivity, which is an important issue as energy use in industry accounts for one fourth of global carbon emission. This study investigates factors affecting energy productivity such as technology innovation, environmental policy and energy price based on firm-level data from the Korean Emission Trading Scheme (KETS). The total factor energy productivity is estimated by industry based on stochastic frontier analysis (SFA) and panel data analysis is performed to identify determinants of firm-level energy productivity. The results show that energy productivity in Korea has been improved since 2016, and technical progress and environmental policy play an important role in promoting energy productivity. In addition, analysis identifying industry-specific characteristics is performed as their production process and energy consumptions structures vary. The result shows that innovation activity does not significantly affect energy productivity in process industries, but it does in the assembling and high technology industries. This paper implies that policy design reflecting industry-specific characteristics is important to improve energy efficiency more effectively.
Have FDI, Globalisation and Energy Security Addressed the Malaise in the Nigerian Economy? A Quantile Analysis
Authors: Musibau Hammed Oluwaseyi , Adenekan Tobiloba Adedoyin , Shittu Waliu Olawale
Published: September 2021

Nigeria, among other developing countries, faces a lot of challenges on growth and global competitiveness as a result of low foreign capital and energy insecurity, among others. Using a quantile-on-quantile regression technique on Nigeria’s data covering 1980–2017, this article examines the impacts of foreign direct investment (FDI), energy security and globalisation on economic growth. Our empirical findings suggest the following: (a) the net impact of energy security on economic growth is negative—implying that energy security impedes growth in Nigeria; (b) globalisation stimulates economic growth across all quantiles, but only significant at the third quantile; (c) as expected, each of labour and capital produces a positive effect on growth; and (d) there exists an adverse, non-significant effect of FDI on economic growth across all quantiles. Similarly, there is evidence of a bidirectional causality between economic growth and FDI; economic growth and energy security; economic growth and globalisation; FDI and globalisation; as well as between energy security and globalisation. There is, however, a uni-directional causality running from energy security through FDI. The policy recommendations of these findings are also explained in the concluding section.
