ABSTRACT

BACKGROUND: The African continent is known for high entrepreneurial activity, especially in the agricultural sector. Despite this, the continent’s economic development is below expectations, due to numerous factors constraining the growth and sustainability of agricultural SMEs. These constraints have been exacerbated by the COVID-19 pandemic. The purpose of this study was to understand the pathways through which the pandemic affected agri-SMEs, with specific focus on assessing the differentiated effects arising from the size of the agri-SME and the gender of the owner-manager.

METHODS: Data was collected from over 100 agri-SMEs, ranging in size from sole proprietorships with one employee to agri-SMEs employing up to 100 people, in six African countries. Mixed methods were used to analyse the data with changes in business operations arising from changing market access, regimented health and safety guidelines and constrained labour supply assessed using visualisations and descriptive statistics. Logistic regression modelling was employed to determine the set of variables contributing to agri-SME business downturn during the COVID-19 pandemic.

RESULTS: All surveyed agri-SMEs were negatively affected by COVID-19-associated restrictions with the size of the firm and gender of the owner-managers resulting in differentiated impacts. The smallest agri-SMEs, mainly owner-managed by women, were more likely to experience disruptions in marketing their goods and maintaining their labour supply. Larger agri-SMEs made changes to their business operations to comply with government guidelines during the pandemic and made investments to manage their labour supply, thus sustaining their business operations. In addition, logistic regression modelling results show that financing prior to the pandemic, engaging in primary agricultural production, and being further from urban centres significantly influenced the likelihood of a firm incurring business losses.

CONCLUSIONS: These findings necessitate engendered multi-faceted agri-SME support packages that are tailored for smaller-sized agri-SMEs. Any such support package should include support for agri-SMEs to develop sustainable marketing strategies and help them secure flexible financing that considers payment deferrals and debt moratorium during bona fide market shocks such as the COVID-19 pandemic.

ABSTRACT

The omnipresence of the same basic equations, function forms, algorithms, and quantitative methods is one of the most spectacular characteristics of contemporary modeling practice. Recently, the emergence of the discussion of templates and template transfer has addressed this striking cross-disciplinary reach of certain mathematical forms and computational algorithms. In this paper, we develop a notion of a model template, consisting of its mathematical structure, ontology, prototypical properties and behaviors, focal conceptualizations, and the paradigmatic questions it addresses. We apply this notion to three widely disseminated and powerful model templates: the Sherrington-Kirkpatrick model of spin glasses, scale-free networks, and the Kuramoto model of synchronization. We argue that what appears to be an interdisciplinary model transfer between different domains turns out, from a broader perspective, to be the application of transdisciplinary model templates across a multitude of domains. We also point out a further feature of template-based modeling that so far has not been discussed: template entanglement. Such entanglement enhances and makes manifest the conceptual side of model templates.

ABSTRACT

This review summarizes the economic impacts of the pandemic on ethnic minorities, focusing on the city of Manchester. It utilizes multiple reporting sources to explore various dimensions of the economic shock in the UK, linking this to studies of pre-COVID-19 economic and ethnic composition in Manchester and in the combined authority area of Greater Manchester. We then make inferences about the pandemic’s short-term impact specific to the city region. Greater Manchester has seen some of the highest rates of COVID-19 and as a result faced particularly stringent “lockdown” regulations. Manchester is the sixth most deprived Local Authority in England, according to 2019 English Indices of Multiple Deprivation. As a consequence, many neighborhoods in the city were always going to be less resilient to the economic shock caused by the pandemic compared with other, less-deprived, areas. Particular challenges for Manchester include the high rates of poor health, low-paid work, low qualifications, poor housing conditions and overcrowding. Ethnic minority groups also faced disparities long before the onset of the pandemic. Within the UK, ethnic minorities were found to be most disadvantaged in terms of employment and housing-particularly in large urban areas containing traditional settlement areas for ethnic minorities. Further, all Black, Asian, and Minority ethnic (BAME) groups in Greater Manchester were less likely to be employed pre-pandemic compared with White people. For example, people of Pakistani and Bangladeshi ethnic backgrounds, especially women, have the lowest levels of employment in Greater Manchester. Finally, unprecedented cuts to public spending as a result of austerity have also disproportionately affected women of an ethnic minority background alongside disabled people, the young and those with no or low-level qualifications. This environment has created and sustained a multiplicative disadvantage for Manchester’s ethnic minority residents through the course of the COVID-19 pandemic.

ABSTRACT

INTRODUCTION: Uncertain situation of the coronavirus disease 2019 (COVID-19) pandemic has led to fear, stigma, and discrimination across all strata of society in varying proportions. Stigmatization increases the suffering of people or those who are at risk of getting the disease and make it harder for public health authorities to control the disease.

MATERIAL AND METHODS: The present study is a questionnaire-based cross-sectional survey conducted over a period of four weeks in the month of July 2021 in a food industry in rural region of western Maharashtra among COVID-19 positive patients. A total of 152 participants were included in the study. The data was analyzed using SPSS software (version 20). Descriptive statistics were used which included frequencies and percentages.

RESULTS: 64.5% of the participants were males and 35.5% were females. Approx. 85% of the participants were in age group 15-58 years. 100% of them reported to have faced fear on being tested COVID-19 positive. However, only approx. 2-5% individuals hid their illness from family and friends and 7.9% of them were afraid of getting hospitalized.

CONCLUSION: It was found that fear was prevalent among all survivors but stigma was found to be minimal which is likely due to widespread awareness through media, IEC campaigns, and active involvement of administration in implementing policies.

ABSTRACT

BACKGROUND: Music therapy has been in use for children with autism spectrum disorder (ASD) since the 1940s. However, there is limited scientific evidence on its use in the Indian context.

AIM: The present study aims to explore musical preferences of children with ASD and their caregivers’ acceptability of music as a form of intervention.

MATERIALS AND METHODS: It is a cross-sectional study of 120 subjects diagnosed with ASD as per the Diagnostic and Statistical Manual of Mental Disorders-5 identified by convenience sampling. A semi-structured interview schedule consisting of 25 objective response questions with multiple choices and 11 open-ended questions (pertaining to music and the use of music) was used to explore caregivers’/parents’ thoughts and beliefs. The responses to open-ended questions were collected in narrative mode. A descriptive approach of content analysis was adopted to analyse the data. The data are presented using descriptive statistics. Institutional Ethics Committee’s approval was obtained for conducting the study.

RESULTS: Most of the children liked (89.2%, n = 107) music and responded (88.3%, n = 106) actively (listen intently/hum or sing or dance along) to music. Most subjects preferred rhythm (65%, n = 78) over melody (15%, n = 18). While 98.3% (n = 118) of the parents were willing to try music therapy for their child, 61% of them (n = 72) asked follow-up questions like – “Is there available data on it?” (n = 12; 10.2%) and “Will it be worth investing our time and efforts on it?” (n = 60; 50.8%).

CONCLUSION: Most of the children including those with auditory sensitivity like music and prefer rhythm over melody. Caregivers possess a positive attitude toward the use of music therapy. However, most of them wish to clarify the scientific basis of the same.

ABSTRACT

BACKGROUND: Depression causes significant morbidity, disability and mortality, along with socioeconomic losses. Patients with depression who don’t remit even with the second trial of anti-depressants need optimization, combination or augmentation strategies. Pharmacological strategies sometimes have unacceptable adverse effects.

AIM: The aim of this study is to compare the efficacy of high-frequency repetitive transcranial magnetic stimulation (HF-rTMS) to left dorsolateral prefrontal cortex (DLPFC) with that of pharmacological augmentation strategies in unipolar non-psychotic treatment-resistant depression.

METHOD: This is a randomized controlled trial.

SUBJECTS: Cases of unipolar, non-psychotic, treatment-resistant depression between ages 20 and 60 years were taken.

PERIOD OF STUDY: The study period was from November 2016 to May 2018.

RANDOMIZATION: Cases diagnosed as per ICD-10 criteria by a qualified psychiatrist. Cases of treatment-resistant depression (100) were divided into two arms by using a random number generator: rTMS arm and treatment as usual (TAU) arm.

INTERVENTION: HF-rTMS to left DLPFC (rTMS group) and pharmacological augmentation with lithium, serotonin-dopamine antagonist, buspirone or thyroxine.

RESULTS: In the rTMS arm, 44 patients and in TAU arm 41 completed the study. After 4 weeks of treatment augmentation, rTMS and TAU groups showed response rates of 52% and 46%, respectively. The difference between the two groups in terms of number of responders at the end of 4 weeks is not statistically significant. Additionally, factors associated with good response to rTMS were absence of a family history of psychiatric illness, no concomitant psychoactive substance use, being first episode of depression and mild-moderate severity of illness.

CONCLUSION: The study did not find rTMS augmentation to be significantly better than standard pharmacological augmentation therapies.

ABSTRACT

BACKGROUND: Although the potential for alternate conceptions of gender roles and sexual orientations are diverse, it is by-and-large not well tolerated. This study explores the self-reported gender-roles and sexual orientations of Indian undergraduate medical students.

AIM: To study self-reported gender role and sexual orientation of undergraduate medical students in India.

METHOD: One hundred twenty volunteers were included in the study consisting of 60 males and 60 females. A questionnaire comprising of a sociodemographic proforma, Bem Sex-Role Inventory (BSRI), and Epstein Sexual Orientation Inventory (ESOI) were given to each participant. The scales were scored, tabulated, and statistically analyzed.

RESULTS: The BSRI revealed that femininity was predominant in both female and male participants, at 68.33% and 55%, respectively. The ESOI revealed that females had significantly higher opposite-sex attraction than males. Though males had higher same-sex attraction than females, the difference was not statistically significant. Females also had a significantly higher sexual orientation range and a mean sexual orientation. Sexual drive was significantly higher in males. Significantly more females supported homosexuality and bisexuality as compared to males.

CONCLUSION: This study helps establish that gender roles can be non-conforming. It helps ascertain that while heterosexual orientation predominates, alternate sexual orientations also exist. It paves the way for future studies and explorations to alleviate public misconceptions.

ABSTRACT

Behind the statistics forecasting millions of deaths associated with antimicrobial resistance (AMR) is an even greater burden of morbidity leaving many people with long-term chronic illnesses and disability. Despite growing recognition of the importance of inter-sectoral and inter-disciplinary knowledge in forming responses to address this global health threat, there remains a paucity of social science research to understand the social burdens of AMR. In this qualitative study we explore the experiences of people living with chronic AMR infections, their interactions with health providers and therapeutic quests for care, and the effects upon their lives and that of their families and caregivers. Our analysis reveals that the resistant infections impacted not only the physical health but also the mental health of the sufferers and their caregivers, causing major disruptions to their social and work lives. Most undertook arduous treatment regimes – of powerful antibiotics with debilitating side effects, combined a range of other complementary and alternate therapies, including travel to seek treatment overseas. Further, we question the notion of ‘AMR survivorship’ currently being promoted as part of a public education campaign by the World Health Organisation and whether people with the diverse AMR experience really self-identify as ‘survivors’ of a biosocial group.

ABSTRACT

Joseph has written what purports to be a refutation of studies of Twins Reared-Apart (TRAs) with a singular focus on the Minnesota Study of Twins Reared-Apart (MISTRA). I show, in detail, that (a) his criticisms of previous TRA studies depend on sources that were discredited prior to MISTRA, as they all failed the test of replicability, (b) the list of biases he uses to invalidate MISTRA do not support his arguments, (c) the accusations of questionable research practices are unsubstantiated, (d) his claim that MISTRA should be evaluated in the context of psychology’s replication crisis is refuted. The TRA studies are constructive replications. Like many other scholars, past and present, he has been misled by the variation introduced by small samples (sampling error) and the distortion created by walking in the garden of forking paths. His endeavor is a concatenation of elision and erroneous statistical/scientific reasoning.

ABSTRACT

AIM: The aim of this study was to evaluate the segmentation accuracy of dentition testing four free-source semi-automatic software.

MATERIALS AND METHODS: A total of 20 cone-beam computed tomography (CBCT) were selected to perform semi-automatic segmentation of maxillary and mandibular dentition. The software tested were Invesalius, ITK-Snap, 3D Slicer and Seg3D. Each tooth model was also manually segmented (Mimics software) and set as the gold standard (GS) reference of the investigation. A specific 3D imaging technology was used to perform the superimposition between the teeth models obtained with semi-automatic software and the GS model, and to perform the surface-to-surface matching analysis. The accuracy of semi-automatic segmentation was evaluated calculating the volumetric mean differences (mean bias and limits of agreement) and the percentage of matching of the tooth models compared to the manual segmentation (GS). Qualitative assessments were performed using color-coded maps. All data were statistically analysed to perform software comparisons.

RESULT: Statistically significant differences were found in the volumetric and matching percentage data (p < 0,05). Invesalius was the most accurate software for 3D rendering of the dentition with a volumetric bias (Mimics) ranging from 4,59 mm3 to 85,79 mm3; instead, ITK-SNAP showed the higher volumetric bias, ranging from 30,22 mm3 to 319,83 mm3. The dis-matched area was mainly located at the radicular region of the teeth. Volumetric data showed excellent inter-software reliability with coefficient values ranging from 0,951 to 0,997.

CONCLUSIO: Different semi-automatic software algorithms could generate different patterns of inaccuracy error in the segmentation of teeth.
