Abstract
India has the highest number of Instagram users in the world. This article examines Instagram, the mobility, and the digital media practices of Delhi Metro commuters before and during the COVID-19 pandemic. In particular, it looks at their photography of everyday lived experiences, their mediated interactions with one another, and the visible-invisible infrastructure in the city. It draws attention to the complexity of digital production, personal archiving, and circulation networks at play. Foregrounding the changing 'geographies of social media', a qualitative, digital ethnographic approach analyses these images' visual, social, and contextual aspects. Also, a range of convergent practices related to individuals, places, and socio-cultural-political-economic-technological realities influence the images. Eventually, a narrative emerges on how these metro travellers inhabit offline and online public spaces, exchange cultural capital, and perform the affective, mediated negotiation of the city.

South Asian governments have introduced renewable energy policies for the reduction of CO2 emissions while keeping up with the demand for food by enhancing agricultural production. Therefore, it is a need to examine the efficiency analysis of agriculture by incorporating CO2 emissions as a bad output for measuring sustainability in their agriculture practices. Also, the study calculated the potential reduction of CO2 emissions and the usage of fertilizers to make agricultural practices sustainable and environmentally efficient. This study estimated the productivity change, technical, and environmental efficiency of rice production for selected South Asian countries. Data were obtained from the FAO‐STAT website from 2002 to 2014. The change in rice productivity was measured through total factor productivity (TFP) scores by applying the Malmquist Index (MI) approach. Traditional data envelopment analysis (DEA) models and Slacks based model (SBM‐DEA) were applied for the measurement of technical and environmental efficiency, respectively. The results of the MI approach showed that Bangladesh, Bhutan, India, Pakistan, and Sri Lanka were found to have positive changes in TFP. The results of technical and environmental efficiency indicated that Bangladesh, Bhutan, and India were found efficient throughout the study period. Afghanistan and Pakistan were found environmentally most inefficient. The slack obtained from the SBM‐DEA indicated that Pakistan, Afghanistan, and Sri Lanka had a huge potential to reduce CO2 emissions and usage of fertilizers. Furthermore, this study provides an overview of the sustainable status of agriculture and also provides suggestions in selected South Asian countries.

Background: This study aimed to evaluate perception of medical students regarding online mode of assessments and to compare the academic outcomes of various methodologies adopted for online formative assessments.Methods: This was a descriptive cross-sectional study. This study was conducted in the department of biochemistry at the constituent medical college of Health University in India and included 150 first year medical undergraduates of either gender. The institutional ethical clearance and written informed consent was taken prior to the study from all the enrolled participants. A series of online formative assessments were designed in the form of multiple choice, short answer questions, case-based learning, and viva-voce to satisfy each learning outcome. Google platform was used for conducting online formative assessment. The participants were asked to fill questionnaire based on 5-point Likert scale to obtain information on challenges and perceptions related to OFA. Academic performance was evaluated and compared for various modes of assessments. Results: The mean age of the participants was 19.34±0.947 years. Most of the students were from urban areas and majority (73.33%) preferred MCQs. 60.67% respondents favored conduction of e-assessments. 80.67% of students agreed that solving clinical cases in the online assessments contributed to clinical learning.Conclusions: Formative online assessment can be used as an intervention to reshape medical education sector during times when infection controls and physical isolation measures are crucial to avoid spread of disease.Keywords: Formative assessment; medical education; online assessment.

Thesis Statement: In spite of being globally prevalent, mental illness faces apathy from the community as well as policymakers and is a point of grave social concern. Health—including mental health—and education are an imperative precondition of achieving the Sustainable Development Goals (SDGs). Education plays a crucial role in inculcating a positive attitude towards mental illness hence high mental health literacy would benefit the society at large. The present research aims to decipher the knowledge and attitude of undergraduate college students towards mental illness. Method: Students of medicine, law and engineering from different colleges in Delhi, India were cross-sectionally surveyed to fathom their attitudinal differences towards mental illness using the CAMI Scale. Results: An affirmative response was observed on Benevolence as well as Community Mental Health Ideology Sub-Scales and a dissenting opinion was identified on the Authoritarian and Social Restrictive Sub-Scales, howbeit significant differences were discerned on the basis of faculty of education. Conclusions and Implications: Results suggested that to accomplish the aspirations of the SDGs there is an ardent need to improve mental health literacy of students. The course curriculum of students needs to be revisited to integrate informative sessions on mental illness.
