Authors: İPEKCİ Afşın , KANBAKAN Altuğ , AKDENİZ Yonca Senem , ÇAKMAK Fatih , BİBEROĞLU Serap , ÖZKAN Seda , İKİZCELİ İbrahim
Published: October 2021

Objective: We aimed to investigate the effectiveness of quick Sequential Organ Failure Assessment (qSOFA), Multinational Association for Supportive Care in Cancer (MASCC), and Clinical Index of Stable Febrile Neutropenia (CISNE) scores in identifying the low-risk febrile neutropenia patients among patients with chemotherapy-associated neutropenia in the emergency department setting.

Material and Method: The risk scores of the patients were calculated and divided into low-risk and high-risk categories according to the guidelines. Serious complications and 30-day mortality were recorded. Patients who survived and did not develop any serious complications were defined as low risk FN.

Results: The median age of the patients was 63 years, and 56.3% were male. Of all patients, 50.6% had hematological malignancy. Blood culture positivity was detected in 31% of the patients. Of all patients, 51 (58.6%) were low-risk FN. The complication rate in patients was 40.2%, while the mortality rate was 25.3%. When evaluated according to the risk scores, 69 (79.3%) patients with qSOFA, 40 (46%) patients with MASCC and 7 (8.1%) patients with CISNE were classified as low risk. The qSOFA score had the highest sensitivity with 96.08%, MASCC had the highest PPV with 85%, and the CISNE score had the highest specificity with 88.89% in patients with low-risk febrile neutropenia.

Conclusion: MASCC, CISNE and qSOFA scores have reasonable discriminating power in identifying low-risk neutropenia patients. The combined use of scoring systems with the clinical gestalt and communication with oncologists will further increase the percentage of the recognized low-risk neutropenia patients in the emergency department.
LAND-LEASING BEHAVIOR, LOCAL OFFICIALS’ PROMOTIONS, AND CHINESE CITIES’ DEBT RISKS
Authors: Zhang Lihua , Han Rui , Zhang Juanfeng , Li Lele , Zhang Danxia
Published: October 2021

This study first analyzes how local governments’ land-leasing behaviors affect Chinese cities’ debt risk then examines the impact of officials’ promotion mechanisms on debt risk in China’s urban land bank system. The land-leasing behavior is reflected through three indicators, namely, land-leasing revenue, land-leasing scale, and land financial dependence level. Two new indicators are constructed to measure the local government’ debt risk from the perspective of debt scale and debt repayment: the debt scale risk and debt burden risk. Empirical analyses are based on the data of 281 prefecture-level cities from 2006–2015. The main findings are twofold. First, the debt scale risk is positively affected by the land-leasing revenue, and officials’ promotion pressure. The debt burden risk is positively affected by the land financial dependence and officials’ promotion pressure. Second, the officials’ promotion pressure significantly enhances the positive effect of land-leasing revenue on the debt scale risk. Local officials, who are under promotion pressure, are inclined to expand the size of urban investment bonds, which increases debt scale risk.

Published: October 2021

BACKGROUND: The burden of disability among the older population is increasing as older people grow with significant social and economic negative impacts.

AIM: This study examines functional disability and its associated risk factors among older Saudi citizens attending primary health-care centers (PHCCs) in Riyadh city.

METHODS: This descriptive cross-sectional study was carried out on 504 older Saudi citizens aged ≥60 years who attended a PHCC in Riyadh city between December 2019 and May 2020. Interviewer-administered questionnaire was used to assessing the disability in activities of daily living (ADL) and instrumental activities of daily living (IADL) using the Katz Index and Lawton scale.

RESULTS: The prevalence of ADL and IADL disability among participants was 24.6% and 58.5%, respectively. Smoking (p = 0.019), dyslipidemia (p = 0.018), rheumatoid arthritis (p = 0.028), history of falls (p = 0.014), and an emergency visit (p = 0.049) were risk factors associated with ADL disability. Predictors of IADL disability were advanced age (p = 0.004), being female (p = 0.029), and the need for a caregiver (p = 0.000). The need for homecare was positively associated with ADL dependency (p = 0.008) and IADL dependency (p = 0.003). Furthermore, regular physical activity was a protective factor against ADL functional disabilities (p = 0.002) and IADL functional disabilities (p = 0.000).

CONCLUSION: This study found a high prevalence of ADL and IADL disability among elderly Saudis. Disability was associated with several sociodemographic and health status factors. The findings of this study highlight the priority of effective and targeted preventive interventions for disability.
The Impact of Multiple Micronutrient Supplementation on Hemoglobin Concentration in Pregnant and Neonatal Birth Wight
Authors: Faris Abdul , Abdullah Muhammad Tahir , Hadju Veni
Published: October 2021

Background: Anemia during pregnancy is a public health problem especially in developing countries and it is associated with maternal and perinatal adverse outcomes.  Global data shows that 56% of pregnant women in low- and middle-income countries have anemia. Every year more than 20 million infants are born with low birth weigh t(LBW) worldwide.
Objective: To analyze the impact of Multi Micronutrients (MM) supplementation on hemoglobin (Hb) levels of pregnant women and infant birth weight.
Method: The databases used to obtain the literature were PubMed, ScienceDirect, MEDLINE, and PubMed Central. The keywords used were Multiple Micronutrien Supplementation, Hemoglobin, Pregnant and Neonatal Birth Weght in studies published from 2010 to 2020. A total of 14 articles were used in this review.
Results: Seven articles obtained about the effects of multiple micronutrients on hemoglobin levels in pregnant women. Six studies support that MM supplementation increases hemoglobin levels or prevents pregnant women from anemia. One study showed a significant increase in serum ferritin One study reported ferritin levels in the MM group as well as the fe-folic acid group did not experience a significant decrease. There is only one study that shows the opposite results, which the mean maternal hemoglobin level significantly decreased during study, being the lowest in second trimester. Ferritin and serum iron levels were decreased at trimester one and two, also the zinc and vitamin D level declined. Seven articles show the effect of MM supplementation on pregnancy outcomes is better than Fe-folic acid supplementation. This can be seen in the results reported from various studies that have been carried out, which are reduce the incidence of LBW, small for gestational age, preterm labor. stillbirths, and NTD anomaly.
Conclusion: Various empirical evidence that has been described in this paper confirms the plausibility that the provision of micronutrient supplementation in the periconceptional period is more important than only given during advanced pregnancy. Multi micronutrient administration increases hemoglobin levels in pregnant women and improves pregnancy outcomes

Approche psychosomatique du passage à l’acte
Authors: Moyano Olivier
Published: October 2021

La polysémie des agirs adolescents est riche et plurielle. Il nous a semblé pertinent d’éclairer cette clinique singulière de l’acte adolescent par les apports de la psychosomatique et plus particulièrement les effets délétères de la perte d’une dynamique interne riche, au profit ou en contrepoint d’une explosion des conduites externalisées. Nous proposerons quelques idées finales autour du paradoxe d’une disruptivité dans un contexte de dépression essentielle adolescente où l’impulsivité cohabite avec l’errance.
Les états-limites : du bébé à l’ado
Authors: Golse Bernard
Published: October 2021

Le concept d’états-limites interroge la nosologie, la psychopathologie et le soin. Ce concept-limite est abordé d’une part au regard de la problématique bébés/ados, d’autre part dans la perspective des structures institutionnelles. L’auteur souligne l’importance d’une lecture à double sens de la théorie de l’après-coup, avant de rappeler quelques repères de la problématique bébés/ados. L’exemple des Instituts Thérapeutiques, Éducatifs et Pédagogiques (ITEP) est enfin pris pour réfléchir aux structures intermédiaires.
Figuration de l’incestuel dans un psychodrame
Authors: Taïeb Olivier , Lambert Nathalie , Le Du Catherine , Baltimore Steeve , Baubet Thierry
Published: October 2021

Le psychodrame psychanalytique de groupe, dans les pathologies narcissiques et psychotiques à l’adolescence, favorise par le jeu le déclin de l’omnipotence au profit de l’ambiguïté. Il ouvre ainsi la voie vers la transitionnalité. Dans cet article est rapportée une séance de psychodrame de groupe au cours de laquelle des agirs incestuels et meurtriels tentent d’être contenus et figurés. Les enjeux thérapeutiques face à cette haine meurtrière sur l’objet-psychodrame sont discutés.

Freud nous incite à être organisé en vue de la mort pour endurer la vie. Le sujet réfugié essaye face à la mort de réorganiser sa vie psychique, de se reconstruire dans l’imaginaire d’une identité secouée par le traumatisme.

Nous aborderons la question de l’adolescent incasable par le biais d’un paradoxe, en évoquant la quête nécessaire de sa nomination par un autre qui le constituera comme sujet. La clinique des adolescents à la Protection Judiciaire de la Jeunesse confronte à la violence de la répétition, mais aussi à l’impuissance et au désarroi. La haine du transfert – et dans le transfert – est essentielle à entendre pour saisir les enjeux de l’adolescent assujetti à cette position d’objet exclu.
Andrea Caffi et la révolution bolchévique
Authors: Labeÿ Marion
Published: October 2021

Cet article revient sur la trajectoire d’Andrea Caffi (1887-1955), militant socialiste et intellectuel italo-russe. Il rejoint la Russie en 1920 pour voir la révolution de ses propres yeux. Témoin de la guerre civile et des réalisations du nouveau régime, il est émerveillé par le caractère populaire de la révolution. L’admiration qu’il témoigne pour les bolcheviks est néanmoins de courte durée. Emprisonné au cours de l’année 1920, il reprend le chemin de l’Italie en 1923, déçu et rejeté par une révolution qui n’est pas la sienne. Ce travail concerne son expérience du régime bolchévique compris comme une rupture biographique mettant fin à un certain idéal révolutionnaire. Son parcours personnel et intellectuel invite à repenser la tension entre engagement et désengagement, l’apolitisme et le refus de la politique existante.
Les possibles de la Révolution allemande (1917-1923)
Authors: Patin Nicolas
Published: October 2021

Le Centenaire de la Révolution allemande de 1918-1919 a soulevé un intérêt certain en Allemagne et a donné naissance à un foisonnement de livres, d’expositions et d’initiatives assez variées. Il est, de ce fait, assez tentant d’effectuer un premier bilan de cette vague du point de vue historiographique, de l’évolution des thèmes et des formes de la recherche. De la même manière que Rüdiger Graf s’est penché sur les « futurs de la République de Weimar », en invitant les historiens à analyser cette période en dehors de son échec final, il sera donc intéressant, aujourd’hui, de jeter un œil nouveau sur la Révolution allemande, en essayant de restituer ce qu’elle comportait de marges de manœuvre, d’imaginaires politiques, de temporalités, d’incertitudes, bref, tout ce qui en faisait, à l’époque, une série d’événements contingents, et non une lente marche vers des formes politiques aujourd’hui connues.
Le féminisme décolonial en Abya Yala
Authors: Curiel Ochy , De Roo Priscilla
Published: October 2021

Les rapports sociaux de race, de genre, de sexe sont inextricablement mêlés : telle est une idée centrale du féminisme décolonial tel qu’il se déploie depuis Abya Yala, du nom que le peuple kuna donnait au continent américain. L’article situe l’importance de renommer les femmes et féministes d’origine autochtone, une manière de défaire les discours coloniaux (parfois tenus par des universitaires féministes) sur les pratiques de genre avant la colonialité/modernité. Ochy Curiel illustre cette idée à partir de l’expérience du GLEFAS (Groupe latino-américain de formation et d’action féministe) : le décolonial n’y est pas seulement une critique du savoir académique, il est profondément ancré dans des pratiques autogestionnaires de luttes anticapitalistes, dans le lesbianisme politique, dans la rue, dans les associations, dans les organisations communautaires.
Cannibaliser le décolonial ?
Authors: Cocco Giuseppe
Published: October 2021

Certaines critiques décoloniales des concepts d’hybridation, de pensée-frontière et de métissage mènent parfois sur le terrain des surenchères identitaires. Certaines analyses affirment que le capitalisme néolibéral ferait son miel des concepts contestataires d’anthropophagie politique qui ont animé la pensée décoloniale brésilienne, d’Oswald de Andrade à Suely Rolnik. Mais, dit Giuseppe Cocco, « le capitalisme contemporain n’est pas anthropophage, il est parasitaire » : s’il aime le métissage, ce n’est pas pour l’assimilation de l’autre, mais pour son extraction sans partage ; il n’est pas une anthropophagie (manger l’autre, et se laisser changer par lui), mais une anthropoémie (le vomir). Ce pourquoi il reste d’actualité de cannibaliser le décolonial.
L’héroïsation de l’immoralité dans les séries TV
Authors: Dramchini Maha
Published: October 2021

Le portrait des héros de séries télévisuelles a progressivement évolué ces dernières années pour faire émerger la figure de l’antihéros, un trope caractérisé par une ambiguïté morale, un système de valeurs individualiste et, paradoxalement, un pouvoir de séduction majeur sur les spectateurs. Il s’agira de comprendre ce qui justifie l’intérêt que l’on porte à ce genre de personnages, et ce que la valorisation de comportements misanthropiques, marginaux ou parfois violents, révèle des valeurs de nos sociétés.
Arabella of Sadness
Authors: Bisson Frédéric
Published: October 2021

Série de l’ère #MeToo, I May Destroy You de Michaela Coel montre que la violence est une potentialité inhérente à la relation sexuelle. Le viol n’est pas le problème spécifique de la série, mais plutôt le cas extrême et paradigmatique qui donne lieu à une problématisation plus générale de la sexualité ordinaire, en une famille de cas hétérogènes. Le point culminant de la série est la manière dont elle transmue le genre du «  Rape and Revenge  », en substituant à la vengeance des formes politiques d’action, par la puissance du récit et de la parole publique.
Regards croisés des approches cognitives et socioculturelles sur l’apprentissage collaboratif : quelles contributions dans le domaine de l’éducation ?
Authors: Molinari Gaëlle , Muller Mirza Nathalie , Tartas Valérie
Published: October 2021

Résumé – Le domaine de l’apprentissage collaboratif réunit des approches pédagogiques se fondant sur l’importance des interactions sociales et de la collaboration pour favoriser l’apprentissage. Les théories associées à ce domaine sont nombreuses, et peuvent se regrouper en deux grandes perspectives : une perspective cognitive qui s’appuie sur des approches rattachées à la psychologie et aux sciences cognitives, et une perspective intersubjective qui fait appel à des approches socioculturelles en psychologie et éducation. Ce chapitre vise à mettre en lumière les contributions et apports spécifiques des approches cognitives et socioculturelles de l’apprentissage collaboratif. Après un aperçu de leurs fondements épistémologiques, nous les sollicitons tour à tour pour répondre à trois questions vives dans le domaine : les interactions sociales et les dialogues ; les environnements numériques ; la dimension affective et le rôle des émotions. La dernière partie du chapitre indique les perspectives que ces approches cognitives et socioculturelles ouvrent, chacune à leur façon mais de manière complémentaire, dans le domaine de l’éducation.
Cesaro summation by spheres of lattice sums and Madelung constants
Authors: Galbally Benjamin , Zelik Sergey
Published: October 2021

We study convergence of 3D lattice sums via expanding spheres. It is well-known that, in contrast to summation via expanding cubes, the expanding spheres method may lead to formally divergent series (this will be so e.g. for the classical NaCl-Madelung constant). In the present paper we prove that these series remain convergent in Cesaro sense. For the case of second order Cesaro summation, we present an elementary proof of convergence and the proof for first order Cesaro summation is more involved and is based on the Riemann localization for multi-dimensional Fourier series.

Open biomass burning (OBB) is a significant air pollution source, but it is still not clear to what extent OBB events affect indoor air quality [1]. Outdoor and indoor measurements of submicron particulate matter (PM1) were conducted on 25–29 April (2019) in the capital city Vilnius (Lithuania). Fires from neighbouring countries (Belarus, Ukraine and Russia) and in the vicinity of Vilnius broke out during the measurement campaign. The temporal evolution and transport of OBB plume were investigated by combining the air mass backward trajectory analysis and fire satellite observation (MODIS) database. Measurements of the PM1 chemical composition in real-time were performed using an aerosol chemical speciation monitor (ACSM) and an aethalometer. Organic matter was the clearly dominant component, accounting for >70%, in both indoor and outdoor PM1. The air filtering system of the office building removed approximately up to 55% of PM1. Despite a significantly lower PM1 pollution level in the office, highly acidic indoor PM1 could have harmful effects on the human health. Source apportionment of particulate carbonaceous matter revealed a significant importance of OBB-related particles (average 56%) to indoor air.

Research results of modified composites which consist of isolated layers with different properties and their practical usages are represented in this article. A structure of the composite material is considered. The structure is combined of few layers; external layers are made of corrosive resistance material with dielectric behavior while the internal part of the composite is made of electrically conductive material with high conductive and mechanical properties. Conductive properties of each layer have been measured as well as their mechanical properties and structure. Also, the features of the joints between layers in terms of structure and properties were defined. More than that, varieties of mixtures and their possible usage are considered. Conductive properties of composite materials and ways of their adjustment have been described as well. For the first time, the measuring scheme of conductive properties for each layer was offered and heat shrinkable tubes and copper electrodes were used for it. Efficiency of modified composites and its behavior when electrical current applied can be measured by using the scheme.

New Possibilities of Determining the Resistance of Cement Composite to Abrasion by Fast Flowing Water
Authors: Pikna Ondřej , Ťažký Martin , Hela Rudolf
Published: October 2021

The current view on the determination of the abrasion resistance of a cement composite is mainly focused on the resistance of the composite to the effects of mechanical abrasion. However, many concrete structures are exposed to the abrasive effects of flowing liquids. One of the test procedures simulating this principle of abrasion is based on the creation of a very fast flow of liquids, often including abrasive media. Based on worldwide published research on the given topic, the use of the action of ultrasonic waves in a liquid, leading to the simulation of the cavitation stress of a composite, which is a very dangerous phenomenon, is considered a suitable method for creating the mentioned abrasion effects. The following article discusses new possibilities for simulating and evaluating the abrasive effects of cavitation on cement composites using the action of ultrasonic waves in a liquid. These effects will be monitored on cement pastes, which will be modified with several types of commonly used admixtures. Furthermore, the connection between the effects of the mentioned abrasive action and several physical-mechanical parameters will be monitored.
Characterization of Carbonatation Rate of Alkali-Activated Blast Furnace Slag in Various Environments
Authors: Dvořák Richard , Hrubý Petr , Topolář Libor
Published: October 2021

Carbonatation represents one of the potential degradation processes whose can negatively affect the service life of constructions based on the inorganic binders. The carbonatation depth of the constructions when exposed to various environments is significantly dependent on the existing conditions. The most crucial parameters are the partial pressure of carbon dioxide and humidity. There were selected four environments for the deposition of samples made of the alkali-activated blast furnace slag mortars (exterior, interior, water and CO2 chamber) in this study. These types of environments guarantee the variation of desired parameters influencing the carbonatation rate. The progress of carbonatation was evaluated with a selected technique in time intervals of 28; 56 and 84 days of the sample's exposition to the selected environments. The characterization was done using the destructive techniques (compressive and flexural strength, phenolphthalein method) as well as the non-destructive one like the Impact-Echo or the Ultrasound time passage measurement. The combination of these techniques allows to determine and evaluate the progress of carbonation without the destructive testing of the samples which is necessary for the real applications of these materials.
Influence of the Chemical Composition of Bauxite on Mineral Formation and Properties of Sulfoaluminate-Ferrite Cement
Authors: Ponomarenko Aleksandr A. , Kapustin Fedor L. , Makarova Elena , Gerasimova Ekaterina S.
Published: October 2021

The influence of the chemical composition of bauxite on the mineral formation and structure of sulfoaluminate-ferrite clinker (SAFC), and physical and mechanical properties of cement based on it is studied. Ferrous bauxite, marble crushing screenings and neutralized fluorine-anhydrite were used for the synthesis of SAFC. The compositions of raw mixes of low-and high-alkaline SAFC are calculated with modular characteristics: Mf (ferritic modulus) = 0.35 and 0.7, Мs (sulfate modulus) = 0.167 and 0.5, respectively. Clinker synthesis from a raw mix containing ferrous bauxite with a quality coefficient of 1.7 must be carried out at a temperature of 1250 °C, which is reduced to 1200 °C for burning a raw mix based on bauxite with a quality coefficient of 2.2. Intensive decomposition of anhydrite occurs with the release of sulfur dioxide into the atmosphere at a temperature of 1300 °C, so it is not recommended to burn SAFC at this temperature. The mineral composition of the obtained SAFC is represented by sulfoaluminate, calcium sulfoferrite and free anhydrite. There is no C2S as a separate phase in clinkers, since in the process of their synthesis belite dissolves in 3С(A,F)·СŜ, mainly in the aluminoferrite phase. The use of bauxite with a quality coefficient of 2.2 in the SAFC raw mix increases the cement activity up to 54.2 MPa. Increasing its specific surface from 350 to 460 m2/kg significantly reduces the setting time of cement paste and increases the strength of sulfoaluminate-ferrite cement both in the early (up to 43.4 MPa) and late hardening periods (up to 67.3 MPa).
Effect of Waste Glass on Portland Cement Hydration Process
Authors: Serelis Evaldas , Vaitkevicius Vitoldas
Published: October 2021

Glass is an amorphous material, which could be a good pozzolanic material and can be beneficial in compressive strength gain. However, if waste of glass powder has undesirable contaminations (aluminium, clay impurities, sulphates, etc.) it can negatively affect hydration process. In the research were used two types of waste glass (with and without harmful impurities). Waste glass shards were obtained from a local waste recycling plant and its properties were investigated in the Portland cement hydration process. Properties of waste glass were analysed by SEM, XRD test methods, pozzolanicity of glass powder was investigated by Chappelle test method. The hydration process of Portland cement was researched by the semi-adiabatic test method and XRD analysis. Properties of hardened cement paste was analysed by: density, flexural and compressive strength test methods The main aim of this research is to analyse waste glass, which after primary cleaning is not suitable for secondary reuse and investigate its suitability in cement-based systems.

Published: October 2021

The competency driven medical education has been introduced in all the colleges of India since 2019. It is mandatory for the students to maintain a logbook under this curriculum, and the use of an annexure to logbook or a portfolio has been recommended. In this paper, we describe the rationale behind using a logbook and portfolio, the differences between the two, the process of implementation, how to assess these, the challenges, the ways to overcome them, and the potential advantages of having such a system in place for various stakeholders. Feedback and reflection are the two processes that will need careful attention to ensure a meaningful implementation of this new introduction.

Authors: Rosen Adam B. , Wellsandt Elizabeth , Nicola Mike , Tao Matthew A.
Published: October 2021

Patellar tendinopathy is a common yet misunderstood condition that afflicts a variety of patient populations. This lack of understanding affects the ability of clinicians to provide effective treatment interventions. Patients with tendinopathy often report long-term and low to moderate levels of pain, diminished flexibility, and reduced strength, as well as decreased physical function. Load-management strategies combined with exercise regimens focused on progressive tendon loading are the most effective treatment options for patients with patellar tendinopathy. This review will provide an evidence-based approach to patellar tendinopathy, including its pathoetiology, evaluation, and treatment strategies.

Authors: Kannappan Suvetha , Gupta Mansi
Published: October 2021

Background:

The health risks faced by textile workers calls for a workplace health system that is comprehensive and accessible. To enhance the capacity of workplaces to strengthen their health system, a toolkit was developed by the Business for Social Responsibility (BSR), a non-profit global business network and sustainability consultancy.

Methods:

The Health System Strengthening (HSS) toolkit was designed to provide a set of tools, resources, and concrete steps for the factory management and health staff to work toward continuous improvement of their on-site health systems. It was then implemented with academic collaboration simultaneously In three factories/ in three manufacturing units/ in three workplaces in South India over 6 months to find out its usefulness as a self-reference tool for HSS. Monitoring and evaluation tools and indicators were developed based on the logic framework.

Results:

The main outcomes of the HSS pilot program include the formation of a health committee which was able to utilize the modules, perform a self-assessment of the health system, and come out with short- and long-term action plans for HSS under expert supervision and guidance.

Conclusions:

Overall, the toolkit was found to be an effective solution for HSS in industries which require expert guidance for implementation.
Hunger, fear, and isolation – A qualitative analysis of media reports of COVID-19-related suicides in India
Authors: Balaji Madhumitha , Patel Vikram
Published: October 2021

Background:

India's suicide rates are among the highest in the world and may increase further as a consequence of COVID-19. There is a need to examine which pandemic related stressors may be contributing to suicide, in order to inform the deployment of suicide prevention strategies, for the current as well as future pandemics.

Aim:

To understand pandemic related stressors contributing to suicide in India.

Methods:

We identified and conducted a thematic analysis of Internet media reports of COVID-19 related suicides in India between February 1, 2020 (2 days after the first COVID-19 case), and May 31, 2020, (the end of phase four of the nationwide lockdown).

Results:

Ten pandemic stressors spanning both disease and lockdown-related factors were identified in 291 suicides. Economic hardship was present in a third; other notable stressors were: fear of the virus; isolation; desperation to be connected with loved ones or return home; and craving for alcohol. Men and young people seemed particularly vulnerable to these stressors.

Conclusions:

COVID-19 related suicides appear to be precipitated by social and economic adversities, mainly associated with containment strategies. These findings need to be confirmed by national suicide data. Suicide prevention strategies should mitigate the impact of recognized stressors in the long term, target high-risk individuals, and offer mental health care alongside containment strategies.

Published: October 2021

Aims:

Special drive campaigns on substance use disorders (SUDs) in India are usually organized in educational institutes, non-governmental organizations, or few selected localities. Hard to reach communities of construction, prison, and industrial sites quite often remain uncovered.

Materials and Methods:

During a month-long special drive in 2019, under a cross-sectional study, we reached these communities of Solan town through awareness camps and incorporated standardized screening tools for evaluating morbidity patterns of SUDs.

Results:

Statistically significant relationship existed between 360 participants (90.8% males, 9.2% females; mean age of 33 years) and their educational levels with χ2 (1, n = 360) =130.59, P = 0.000. Fagerstrom's scale inferred very high nicotine dependence in 10.6%, 7.9%, and 2.4% of prisoners, industrial workers, and laborers, respectively. Whereas, Fagerstrom scale for smokeless tobacco revealed 31% of significant dependence potential amongst laborers. Alcohol use disorder identification test revealed 28 persons with harmful alcohol dependence. Drug abuse screening test revealed 13.6% of prisoners having moderate level drug abuse potential. The Kruskal–Wallis test showed a statistically significant difference, in levels and potential of substance use in construction, prison, and industrial sites.

Conclusion:

The study proved the utility of special drives in evaluating SUDs morbidity patterns in hard-to-reach communities.

Background:

Craving is the subjective experience of desire for specific drugs. Lack of reliability and untested construct validity are limiting factors for the existing questionnaires to assess craving.

Aim:

The aim of the study was to design and test the validity and reliability of an instrument to assess visual cue-induced craving for heroin dependence.

Materials and Methods:

In the first stage of the study, a set of forty images (twenty each of heroin and neutral cues-) were captured and validated by expert consensus. Thirty male participants with heroin dependence rated their cue-induced craving on a six-point Likert scale while viewing this image-set. In the next stage, putative construct validity was examined using a pilot cue-reactivity functional magnetic resonance imaging paradigm with ten additional heroin-dependent patients.

Results:

Cronbach's alpha for the instrument for visual cue-associated craving of HEroin (IV-CACHE) was 0.9, suggestive of high internal consistency. There were modest and significant correlations of IV-CACHE with the drug desire questionnaire (r = 0.43), and obsessive-compulsive drug use scale (r = 0.37), supporting concurrent validity. Patients with heroin dependence exhibited cue reactivity in the left fusiform area, right lingual gyrus, right precuneus region, right inferior frontal, inferior temporal gyri, and middle occipital gyri. The activated brain areas were largely aligned to the underlying neurobiological substrates of craving but might also have depicted nondrug-specific factors (aberrant face processing and attentional bias).

Conclusion:

The present cue-task is a promising tool for the examination of cue-related craving for heroin in the Indian setting.

Background and Aim:

MSM in India experience complex and multiple psychosocial challenges. The current study was conducted with an aim to assess the magnitude and predictors of psychosocial health-related problems including MSM registered in targeted intervention centers in Delhi.

Methods:

A cross-sectional study was conducted among 235 MSMs. Burden of psychosocial health issues among MSM including depression, anxiety, substance abuse, and partner violence was assessed using semistructured questionnaire. Chi-square test was used to study the association of sociodemographic characteristics and psychosocial issues among the study participants.

Results:

The prevalence of depression, anxiety, substance abuse, and partner violence was 45.1%, 37.8%, 27.6%, and 8%, respectively. Age (<24 years), education up to middle school, and being single had significant association with depression. Being sex worker as occupation had a significant association with anxiety and intimate partner violence.

Conclusions:

The study reveals a significant burden of psychosocial problems and throws light toward broadening the spectrum of health assessment among this vulnerable group.
On existence of quasi-Strebel structures for meromorphic $k$-differentials
Authors: Shapiro Boris , Tahar Guillaume
Published: October 2021

In this paper, motivated by the classical notion of a Strebel quadratic differential on a compact Riemann surface without boundary we introduce the notion of a quasi-Strebel structure for a meromorphic differential of an arbitrary order. It turns out that every differential of even order

k\ge 4

satisfying certain natural conditions at its singular points admits such a structure. The case of differentials of odd order is quite different and our existence result involves some arithmetic conditions. We discuss the set of quasi-Stebel structures associated to a given differential and introduce the subclass of positive

k

-differentials. Finally, we provide a family of examples of positive rational differentials and explain their connection with the classical Heine–Stieltjes theory of linear differential equations with polynomial coefficients.
The Regulation of Cryptocurrencies under Ethiopian Legal Norms
Authors: Gobena Messay Asgedom
Published: October 2021

Cryptocurrencies are a subset of virtual currencies that have been devised for anonymous payments made entirely independent of governments and traditional financial institutions. The payment system of cryptocurrencies is expanding at a rapid pace and has reached Ethiopia. This article examines the extent to which cryptocurrencies are regulated under Ethiopia’s national payment system and anti-money laundering legal norms. The study has employed doctrinal research supported by in-depth interviews. During the last decade, Ethiopia has adopted several legal frameworks that govern different aspects of the payments landscape, most notably regarding payment services and electronic money. The country has anti-money laundering legal norms that are embodied in domestic laws and international and regional instruments that it has ratified. However, these legal norms have strategic deficiencies in regulating cryptocurrencies. Thus, the government of Ethiopia should consider enacting a comprehensive law that regulates the payment system of cryptocurrencies.
Alteration of Consumption Habits in Turkey Over Time
Authors: Akarsu Mahmut Zeki
Published: October 2021

Simon Kuznets and John Maynard Keynes did research on the subject of propensity to consume. Kuznets asserted that people do not alter their consumption/saving ratio and spend more when they have more disposable income. Keynes alleged that when disposable income increases, the rate of saving also increases over time because people tend to keep their consumption habits steady. Namely, the consumption/saving ratio of households or individuals tends to decrease as disposable income goes up. And in this study, the Keynesian consumption function is investigated in the Turkish economy. The result of this research might give insight into the future of the consumption/saving ratio in Turkey. In the study, the ARDL econometric model is operated with data from the Turkish Statistical Institute. The result of the study is that people change their consumption habits with the increase of disposable income. As a result, the consumption level has been slowing down, and the propensity to consume diminishes. That proves that the Keynesian consumption function holds in Turkey.

The main objective of this study is to evaluate Citizenship Education (CE) literature through systematic bibliometric analysis. The science mapping method was conducted to analyze data. Because CE is also studied with the names of social studies and civic education in the literature, articles related to these topics were included in the study. 4029 articles and proceeding papers that were obtained from the WoS database were analyzed. As a result of the study, it was revealed that number of publications has been dramatically increased in recent years. Moreover, Theory and Research in Social Education Journal was found as the most relevant source in terms of number of publications about CE. Furthermore, the study conducted by Westheimer and Kahne in 2004 was determined as the most influential source that has the most citations per year in the field. Finally, it was found that USA and UK are the most productive, most cited, and most collaborative countries in terms of scientific publications.
The Impact of Self-assessment on Academic Performance: A Meta-analysis Study
Authors: Karaman Pınar
Published: October 2021

This meta-analysis study synthesizing the results of experimental and quasi experimental studies examined the effects of self-assessment interventions on student academic performance from primary education to higher education. A total of 16 studies with 46 effect sizes involving more than 7,650 participants were included in the analysis. Research synthesis showed that an overall small influence of self-assessment interventions on academic performance (g=.37, p .05). Additionally, moderator analysis was used to examine moderating effects of some variables. The analysis indicated that traditional self-assessment interventions without external feedback have significantly a larger effect (g =.47, p.05) than self-assessment with external feedback (g=.28, p.05) on academic performance. However, effectiveness of other moderating variables (e.g. education level, assessment criteria type, self-assessment training) on academic performance were not statistically significant. The results suggest that further empirical studies are needed to reveal the moderating effects of self-assessment.
Promoting Inquiry Based Learning through Entertaining Science Activities
Authors: Lozano Oscar Raul , Solbes Jordi
Published: October 2021

Considering students’ increasing lack of interest and motivation for science subjects, it becomes almost imperative to introduce different methodology approaches in classrooms. Besides, decontextualized science teaching, where hands on activities are not sufficiently taken into account, can make the students attitude toward science-learning even worse. Inquiry Based Learning where elements such as games, toys and short experiments are included is showed as a useful methodological proposal. This paper presents how the use of these entertaining science activities can improve students’ interest and encourage them to speak about science, acquiring better argumentation and inquiry skills when they are properly performed in a formal classroom context.

Published: October 2021

The aim of this paper is to share part of an ongoing study in which we are interested in introducing a Gallery Walk (GW) as an instructional strategy to contemplate in the classroom, in the context of preservice teacher training for elementary education (6-12 years old), to promote students' mathematical knowledge and skills, through problem solving abilities. In this study we intend, in particular, to identify the strategies used by students when solving challenging tasks with multiple approaches, using a GW, as well as characterize their reaction during their engagement in the GW as a teaching and learning strategy. A qualitative and interpretive study, with an exploratory approach, was adopted and the collected data included classroom observations and written productions. The results allowed to identify the strategies used by the participants and to verify the potential of the GW in the quality of the written productions and discussions, which proved to be more effective than in more traditional discussions, allowing to increase the repertoire of solving strategies of each student and communication and collaborative skills; it had a positive effect on the participants’ achievements and it was an enjoyable and rewarding experience for all of them.

Authors: Hebebci Mustafa Tevfik
Published: October 2021

This research determines the trends of academic articles on distance education in the COVID-19 epidemic and provides a roadmap for possible future studies on this topic. In this context, bibliometric and content analysis methods were used. Research data were collected through the Web of Science (WOS) database. As a result of the filtering process on WOS, 767 scientific articles were included in the research. In the data analysis process, the articles were reviewed in terms of the year, country, journal, publication language, citation, co-authorship, co-occurrence, and co-citation. Research results indicate that the articles were published between 2020 and 2021 and generally in English. “Journal of Chemical Education” is the journal with the most publications and the most cited and co-cited journals. The USA draws attention as the country that publishes the most, has the most citations, and cooperates the most. The most cited article was conducted by Chick et al. According to the co-occurrence analysis, it is seen that the terms “COVID-19” and “distance learning” are frequently used by the authors. The findings were discussed within the framework of the literature, and other studies and suggestions were made.
