    Abstract

    Cities are characterised by social and cultural diversity. The management of urban wildlife requires developing a better understanding of cultural beliefs associated with wildlife in diverse urban settings. We document a range of cultural beliefs associated with the slender loris (Loris lydekkerianus), an endemic, nocturnal primate, in the Indian megacity of Bengaluru. Many residents associate the loris with practices such as black magic, and they believe that the animal’s call is a bad omen that brings death and misfortune. Others consider it a harbinger of good luck that offers protection to young children. These superstitious beliefs may motivate illegal wildlife trafficking of the loris. Urbanisation has led to changes in these perceptions, and many respondents now report that they consider these beliefs to be old-fashioned superstitions that hold no place in a modern city. This study contributes to knowledge on changing urban attitudes to wildlife, which is vital to developing conservation strategies that involve local residents.

    Abstract

    Utilising data from the Periodic Labour Force Survey, the researchers estimate quarterly changes in urban labour market flow over the period 2018 to 2022 and the impact on unemployment rates for men and women. Their analysis provides non-intuitive explanations for established findings as well as points out important questions for further study. Both men’s and women’s unemployment rates have reduced in 2022 compared to 2018, showing rapid reductions following the high levels reached during the lockdown. Women’s unemployment rates have consistently been higher than men’s throughout this period. The gap between men’s and women’s unemployment rates reduced during the lockdown, but has shown signs of increasing since 2021, even as unemployment rates have fallen. For women, flows from the labour force to non-participation play a larger role in explaining changes in unemployment rates as compared to men. Flows from the labour force to non-participation, however, have reduced since the pandemic, providing an explanation as to why labour force participation rates have increased, namely, women staying for longer in the labour force rather than more women entering it. Despite rising labour force participation rates, the gender gap in unemployment rates has risen, in contrast to developed economies.

    Abstract

    Due to the heavy-quark symmetry of Non-Relativistic Quantum Chromodynamics (NRQCD), the cross-section for the production of ηc can be predicted. This NRQCD prediction when confronted with data from the LHCb is seen to fail miserably. We address this LHCb ηc anomaly in this paper using a new approach called modified NRQCD, an approach that has been shown to work extremely well for studying J/​ψ, ψ′ and χc production at the LHC. We show, in the present paper, that the predictions for ηc production agrees very well with LHCb measurements at the three different values of energy that the experiment has presented data for. Modified NRQCD also explains the intriguing agreement of the LHCb ηc data with the colour-singlet prediction. The remarkable agreement of the theoretical predictions with the LHCb data suggests that modified NRQCD is closer to apprehending the true dynamics of quarkonium production.

    Authors

    Abstract

    The article argues that industry is coming alive to its social purpose, with considerations like equity, environmental impact and ethics. It starts with the history of industrial revolutions from 0.0 to 4.0, detailing their impact on society. It goes on to introduce the concept of Industry 5.0, which is built on the principles of human centricity, sustainability and resilience. The author explains the implications of Industry 5.0 to society, leadership, and HR. He argues that Industry 5.0 is not a revolution but an evolution of the manufacturing process, which is characterised by the integration of various technologies such as artificial intelligence, the Internet of Things, and robotics. He concludes by discussing how individuals can adapt to the requirements of Industry 5.0. The article points to Industry 5.0 becoming more humane with greater responsibility for equity, justice, and sustainability.

    Abstract

    This paper looks at a case of rural-to-rural movement of agrarian capital in southern India and the ways in which capital-labour relations are reworked to maintain oppressive forms of exploitation. Faced with an agrarian crisis, capitalist farmers from affluent communities of Wayanad, Kerala, take large tracts of land for lease in the neighbouring state of Karnataka and grow ginger based on price speculation. Landless Adivasis from Wayanad have served as labourers on these ginger farmlands for the past three decades. Recently, farmers have shifted to employing labourers from a Scheduled Caste (SC) from Karnataka. The change happened not just because of the lower wages the SC labourers were willing to work for, but also because of the farmers’ inclination to move away from Adivasis who have been resisting the poor working conditions on the farm. The story resonates with broader dynamics of agrarian-labour relations amidst capitalist expansion and highlights the centrality of socio-political factors at play.

    Abstract

    In this entry, the researcher will analyse neoliberal policies and how they have been popularised through the mass media – with a particular focus on market triumphalism. This is an important issue in contemporary times as neoliberal policies have led to an increase in economic inequality. However, public discourse has argued that these policies are beneficial to the economy and workers. The first section will describe the historical trajectory that shaped neoliberal policies. In the second section, the researcher will trace the introduction of neoliberal policies in India in the 1990s and how English newspapers popularised them. In section Sandel’s Critique of Market Triumphalism in America”, the researcher will discuss the popularity of market triumphalism through neoliberal policies in the USA and Michael Sandel’s (What money can’t buy: the moral limits of markets. Penguin, London, 2012) influential critique of it.

    Abstract

    At the time when Saussure or Pierce were propounding and formulating their ideas about the relationship between a concept and the multiple ways they can be referred to, the world was still going through the extended effects of the industrial revolution. The world was still connecting and finding out that there could be multiple ways of referring to most concepts around us. But fast forward a hundred years and the world has changed a lot. Concepts have changed and we now live on an earth that is more connected than ever and new languages’ keep cropping up once in a while. The concept of sign propounded has had a big role to play in the structure of language, at least from a theoretical point of view. The idea of sign has evolved over time and this paper presents a discussion of the relationships between signifiers and signifieds.

      Abstract

      Wellbeing is a complex concept and while a wellness-focused school culture is key, it also requires a very individualised focus. Children function at the level of emotions. Their wellbeing depends on how the school, teachers, other students, and the entire ecosystem make them feel. In this issue, there are several articles that should make us think about how a child who is excluded feels. How does a child whose family life is full of strife feel in school? Why does another feel that no one would visit their home because they are poor or belong to a lower caste?

      Abstract

      Azim Premji University, in collaboration with 9 Civil Society Organisations (CSOs), conducted a survey of 3,000 households in 92 low-income settlements across 39 wards of Bengaluru. The survey was done to estimate the continuing impact of COVID-19 induced lockdowns and economic disruptions on employment and livelihoods. The survey also captured information on access to government support as well as coping mechanisms to deal with such a crisis. Workers in a wide range of occupations such as drivers (cab, auto, and others), daily wage workers (construction and others), domestic workers, and factory workers (garment and others) were surveyed. The survey was conducted in the month of November 2021 with the help of Action Aid, Association for Promoting Social Action (APSA), The Center for Advocacy and Research (CFAR), Hasiru Dala, Gubbachi, Reaching Hand, Sangama, Swabhimaan Trust, and Thamate.

      Abstract

      The globally invasive Argentine ant (Linepithema humile) possesses a venom lethal to some amphibian species in the invaded range. To test the novel weapons hypothesis (NWH), the effects of the toxin on the cohabiting amphibian species in the ant’s native range need to be investigated. The invader should benefit from the novel chemical in the invaded range, because the species are not adapted, but the venom should not be effective in the native range. The researchers explore the venom effects on juveniles of three amphibian species with different degrees of myrmecophagy inhabiting the ant’s native range: Rhinella arenarum, Odontophrynus americanus, and Boana pulchella. They exposed the amphibians to the ant venom, determined the toxic dose, and evaluated the short-(10 min to 24 h) and medium-term (14 days) effects. All amphibian species were affected by the venom independently of myrmecophagy. In addition to amphibian sensitivity, the researchers discuss how the differential Argentine ant abundance and density in the two ranges could be the key to the susceptibility of amphibians to the venom, resulting in the possibility of NWH. Their results confirm the potential magnitude of the impact of the Argentine ant in successfully invaded areas for the conservation of already threatened amphibians.

      Abstract

      In India, as in many countries around the world, most government jobs are allocated through a system of merit-based exams. Over the past few decades, these exams have become incredibly competitive, at times receiving over 1,000 applications for each vacancy.

      Against a backdrop of rising educational attainment, high aspirations, disappointment with private sector opportunities, and a deep unmet need for income security, it is understandable why the demand for public sector employment opportunities is so high.

      Yet despite the large footprint that public sector recruitments have in our social, economic and political life, many basic questions about them remain shrouded in mystery. Who applies? Why do they apply? Are these intense levels of competition socially productive, or do they make people worse off? Why are people willing to invest so much in exam preparation? Why are people willing to gamble on such low odds of getting selected?

      Our lack of understanding limits our ability to formulate sound labour market policy. As we will see, a large share of college graduates participate in public sector recruitment exams, and candidates for these exams make up a disproportionate share of the overall unemployed population. How can we improve employment outcomes if we do not understand who the unemployed are and how they invest their time?

      The main reason for the holes in our understanding is a lack of data. To date, neither private nor public household surveys include questions on whether individuals are preparing for competitive exams; and recruitment agencies have historically been cloistered institutions, understandably concerned about protecting the integrity of the recruitment process. As a result, the crores of candidates preparing for competitive exams around the country remain largely invisible in data, and by extension in policy.

      This report attempts to shine a light on this dark corner of the labour market. To do so, the researcher uses several new sources of data. First, he draws on administrative data from a recruitment agency. This data allows us to observe the whole recruitment process for the entire universe of applicants — the first time such data has been made available in the Indian context. 

      Second, the researcher uses data from a large-scale survey of over 3,000 candidates, which provides information about their investments in exam preparation, their access to resources, their constraints, and their beliefs. 

      Third, the research collaborators and the researcher conducted interviews and focus groups with candidates to better understand them in their own words. These rich data sources provide new insights into the economic and social life of candidates preparing for competitive exams.

      The goal of this report is to demonstrate how both labour market and recruitment policy can be informed by a better understanding of candidate application behaviour. This understanding can, in turn, help us tackle some of the key challenges in the modern Indian labour market — high levels of educated unemployment, a lack of skill development, low levels of female labour force participation, and more.

        Abstract

        Culture-specific knowledge plays an important role in shaping environmental conservation. Yet we lack a holistic and contemporary understanding of how such local cultural systems interface(d) with ecologies, especially in the fast-growing cities of the Global South which face profound environmental challenges. In this paper, we explore nature-based cultural systems embedded in folk-songs to understand situated social-ecological histories of human-inhabited peri-urban landscapes in the city of Bengaluru in South India. Drawing on empirical observations from the city, we trace local imageries of erstwhile lake-based social systems through folk-songs, mythologies and oral narratives. We demonstrate how many of these cultural narratives, largely embedded within symbolic linkages to the lake ecology, continue to manifest themselves as folk expressions in the city, despite the fact that most of the lakes have been polluted or are managed via restrictions that prohibit village residents from accessing them as they once did for agriculture, livelihoods and domestic use. The songs are also rich reminders of socialities, which, despite being divisive and hierarchical to a large extent, were symbolically and materially embedded in nature.

        Abstract

        The article explores the emergent tension between the minority imagination and anticaste politics among India’s most significant religious minority, the Muslims. Since the late 1990s, the mobilisation of lowered-caste Muslims in the form of the Pasmanda movement has increasingly challenged the hegemony of the so-called high-caste Ashraf Muslims. The nascent Pasmanda counterdiscourse has contested the critical elements of the entrenched Muslim-minority discourse: identity and the religio-cultural, security and interreligious (communal) violence, and equity and affirmative action. The monolithic image of the Muslim community has been dispelled, and the Muslim-minority discourse has been characterized as a machination for preserving and reproducing the Muslim elite interests. The article maps the Pasmanda discourse and locates it as an instance within the evolving literature on the analytical limitations of the concept of minority to address the justice claims of emergent political subjectivities. The Pasmanda contestations present a sharp anomaly to the existing Muslim-minority discourse and indicate a paradigmatic shift.

        Temporality is recognised as critical to the understanding of childhoods by contemporary scholars of childhood. This paper explores the varying temporalities through which marginal childhoods (and their educational inclusion), particularly those situated in contexts of temporary internal migration, are constructed in the Indian context. Drawing on ethnographic data from the city of Bengaluru, this paper problematises how dominant ideals around migration, childhood, and schooling frame migrant children’s lives through linear temporalities. Furthermore, the paper argues that policy interventions that ostensibly include migrant childhoods do not engage critically with the politics of linear temporality which, in turn, is central to the exclusionary dynamics of migrant children’s schooling. linear temporality; marginal childhoods; educational inclusion; temporality of schooling; migrant childhoods and temporality.

        Abstract

        The present article examines the efforts of the Hindu conservatives at securing support for a law to ban cow-slaughter during the intervening years of India’s Independence. It also critically examines the debate on this question in the Constituent Assembly of India. Through this examination the article notes how the Hindu conservatives prepared the ground for a law against cow-slaughter even prior to the question being debated in the Constituent Assembly. Further, it argues that by an exclusive consideration of the views of the practitioners of conservative Hindu religion, whose ideology is based on a monolithic conception of Hinduism, over cow and conversely disregarding the others’ views, particularly of Islam on the same, the makers of the Constitution of India sought to impose a Hindu religious practice upon the non-believers of Hindu religion. The article also highlights the role of Ambedkar in the making of Article 48. The article is divided into three sections, wherein the first section looks at the Hindu conservatives’ attempts at securing support for a law against cow slaughter, the second and third sections analyze the debate over the question of cow-slaughter in the Constituent Assembly of India.

        Abstract

        Classroom assessment is the process of documenting the knowledge, skills, attitudes and beliefs of learners. It provides essential feedback to both instructors and students to improve their teaching methods for guiding and motivating students to be actively involved in their learning. Assessment drives learning. Formative assessments enable the instructor to guide the students to learn well. Summative assessments enable the measurement of levels of attainment of course outcomes and act as feedback to course design and curriculum improvement. This article presents the underlying principles of assessment through a discussion of assessment approaches and their purposes, types of assessment items, quality of assessment and summative assessment plans. Quality assessment instruments can be developed through an understanding of the quality attributes of assessment items, the process of designing assessment instruments, designing a variety of assessment items, and devising plans to evaluate them through rubrics. An approach is presented for creating a summative assessment plan that can also lead to the attainment of outcomes as per the requirements of programme accreditation.

        Abstract

        The social – ecological systems (SES) framework (Ostrom 2009, Science. 325(5939):419 – 22) typologically decomposes SES characteristics into nested, tiered constituent variables. Yet, aligning the framework’s concepts of resource system (RS) and resource unit (RU) with realities of individual case studies poses challenges if the underlying SES is not a single RS, but a mid to large-scale nested RS (NRS). Using a diagnostic approach, we describe NRSs — and the activities and networks of adjacent action situations (NAAS) containing them. An NRS includes the larger RS and multiple interlinked semi-autonomous subsidiary RSs, each of which support simultaneous, differently managed appropriation of individual RUs. We further identify NAASs operating within NRSs in two diverse empirical cases — networks of lake systems in Bengaluru, India and German wheat breeding systems — representing a lever towards understanding transformation of SESs into sustainable futures. This paper contributes towards unpacking and diagnosing complexities within mid to large-scale RSs and their governance. It provides a generalizable, rigorous approach to SES case study analyses, thereby advancing methods for synthesis in sustainability science.

        Abstract

        People in rural India routinely experience a vast difference between what is promised by the state and what is realised on the ground. Panchayati Raj Institutions (PRIs) enable a broad spectrum of actors to be involved in planning the activities of the local state and holding the bureaucracy accountable for their actions at this level. While literature shows that clientelism is pervasive and affects the performance of PRIs adversely, there are pockets of evidence where programmatic transactions regularly occur. I use programmatic and clientelistic transactions as ideal types of outcomes and exploring how these transactions are engendered through a comparative study of two Gram Panchayats with similar institutional settings using ethnographic materials. Together with institutional design and economic factors, differences in local political dynamics affect development outcomes. Individualistic and loyalty-driven leadership prompts symbiotic relationships with bureaucrats, whereas cadre-based leadership prefers control and scrutiny. The expectations of villagers from their panchayat are also shaped by these political traits. In the first scenario, bureaucracy uses procedural compliance to hide clientelist decisions from scrutiny, whereas in the second, it is used to demonstrate neutrality in decision making.

        Abstract

        The present study analyses civic and community-based initiatives in conserving urban ecological commons in India, which have been increasingly polluted, encroached upon and degraded because of rapid land-use transformations. Bangalore, a city in south India, has one of the largest networks of manmade lakes, some of which are restored and managed by citizen groups, civil society, environmental activists and voluntary private bodies. The restoration process interfaces with urban policy making, shaping predominant management agendas in association with the State. Community initiatives in conserving the lakes are not only well-organised, but also play a crucial role in making city commons vibrant and integral nodes of cultural and social identification. However, the contemporary management system involving citizen groups in lake conservation is largely at odds with the tradition of community-managed lake systems previously existing in the city, which have eroded as the city became industrialised and increased in size and population, resulting in rapid landscape transformations. Against this background, the present study aims to illustrate that a seemingly representative community management of city ecologies is often embedded in an overwhelming political context. It also discusses the need for an urgent deconstruction to better understand how overtly flexible and dynamic restoration actions interact with inequality, power and conflicts. The results of the present study emphasise that the current participatory and community-driven initiatives of ecological restoration in Indian cities unfortunately accord limited significance to the overarching questions of social justice and relations of power.

              Authors

              Abstract

              This study examines the performance of MGNREGA during the Covid-19 pandemic in eight blocks across four states of India, viz. Bihar, Karnataka, Maharashtra and Madhya Pradesh. MGNREGA functioning is analysed along the following dimensions: overall impressions of the programme among job card holding households, extent of unmet demand, wage payments, changes in programme functioning during the pandemic, and effectiveness of MGNREGA as a safety net. The blocks were chosen from a list of blocks in which Civil Society Organisations part of the NREGA Consortium are working. All blocks on this list were ranked based on their performance in MGNREGA as reflected in the Management Information System (MIS). Highest and lowest ranked blocks were chosen in each state and are referred to as high performing and low performing blocks in the study The blocks chosen were — Phulparas (Madhubani) and Chhatapur (Supaul) in Bihar, Bidar (Bidar) and Devadurga (Raichur) in Karnataka, Khalwa (Khandwa) and Ghatigaon (Gwalior) in Madhya Pradesh, and Wardha (Wardha) and Surgana (Nashik) in Maharashtra. A two stage random sampling was followed in the chosen blocks. In the first stage, five Gram Panchayats (GP) were randomly chosen in each block based on the Census 2011 list. In the second stage, 50 households were randomly selected in each GP from the MGNREGA MIS list of job card holders. The sampling method ensures representativeness of the results at the block level for all job card holding households. The survey was conducted in November-December 2021. Two reference periods were employed. The first covered the pre-Covid financial year (April 2019 to March 2020) and the second covered the Covid financial year (April 2020 to March 2021).

              Abstract

              Batesian mimicry imposes several challenges to mimics and evokes adaptations in multiple sensory modalities. Myrmecomorphy, morphological and behavioral resemblance to ants, is seen in over 2000 arthropod species. Ant-like resemblance is observed in at least 13 spider families despite spiders having a distinct body plan compared to ants. Quantifying the extent to which spiders’ shape, size, and behavior resemble model ants will allow us to comprehend the evolutionary pressures that have facilitated myrmecomorphy. Myrmaplata plataleoides are thought to closely resemble weaver ants, Oecophylla smaragdina. In this study, we quantify the speed of movement of model, mimic, and non-mimetic jumping spiders. We use traditional and geometric morphometrics to quantify traits such as foreleg size and hindleg size, body shape between the model ant, mimic, and non-mimics. Our results suggest that while the mimics closely resemble the model ants in speed of movement, they occupy an intermediate morphological space compared to the model ants and non-mimics. Ant-mimicking spiders are better at mimicking ants’ locomotory movement than morphology and overall body shape. Some traits may compensate others, suggesting differential selection on these mimetic traits. Our study provides a framework to understand the multimodal nature of mimicry and helps discern the relative contributions of such traits that drive mimetic accuracy in ant-mimicking spiders.

              Abstract

              In a homogenised imagination of human aspirations, development interventions replicate popular models, including intensive farming in Adivasi landscapes. In the process, they try to sedentarise and individualise Adivasi communities living in the forest peripheries. Even as modernisation remains an elusive target in most of the tribal belts, ethnic socio-ecological institutions become redundant, leaving the community deskilled — ecologically, socially, and economically. Adivasi’s concerns about this conventional development process entailing detribalisation are seldom deliberated in literature and among the community.
