Reducing gender disparities in workforce participation is an important policy goal in several developing countries. India, in particular, has historically had low levels of women’s workforce participation as compared to men and as compared to peer economies. Prior research has identified both supply and demand-side explanations for low levels of women’s participation in paid work. On the supply side, social norms constraining women’s mobility and autonomy are commonly invoked as one explanation. We test the relevance of such norms in explaining heterogeneity in women’s employment using district-level data from the National Family Health Survey (NFHS) 2015 – 16 and the Sixth Economic Census (2013). Norms indices are constructed using Principal Components Analysis for 640 districts of India. The findings indicate that less restrictive norms related to decision-making, mobility, and asset ownership are positively correlated with higher levels of women’s employment.

The November 2025 issue of At Right Angles takes a look at the annual celebration of the National Day of Mathematics on December 22. Celebrating mathematics makes perfect sense to some, far less to others- with the articles in this issue, we hope to make persuasive arguments that cause shift towards those who love patterns, who enjoy discovery, who believe in celebrating reason, elegant arguments – in short, Mathematics!

The need to strengthen comprehensive primary health care towards ensuring ​“Health for All” is well established yet operationalising this has remained a challenge globally as well as in India. Based on a qualitative study of a collaborative initiative between the government and a civil society organisation, this article discusses what factors and processes explain successful implementation of primary health care in a remote rural area in central India.

The present paper is a conceptual paper which explores the innate nature of languages exploring how they are in constant flux. From their sociological birth to them being politically accepted, languages go through a plethora of changes. This paper explores concepts like high and low varieties of language e.g., Hindi in playgrounds and Hindi used to teach; the concept of prestige associated with a language, as well as concepts like elaborate and restricted code by Basil Bernstein. It explores the creole continuum and how they are connected to language death. Diglossic conditions may also lead to languages being used over another leading to language disuse. Certain linguistic groups, despite having a working language, assimilate themselves with a larger language due to many possible reasons (economic, political, geographical or anything else). This paper will take the discussion forward with how policy decisions can also lead to systematic extinction of certain languages due to the farsightedness of language planning. Paulo Friere (Friere, 1985) spoke about how local languages can be the backbones of language education. This paper explores the inability of state level language planning policies at incorporating local languages into the curriculum leading to eventual endangerment of the language over generations. This paper will also look at languages with shared script and how it might be the result of language imperialism over centuries.

The objective of this study was to assess the impact of short-term fasting and subsequent re-feeding cycles on compensatory growth performance, blood glucose levels, and digestive enzyme activity in mono-sex juvenile Nile tilapia (Oreochromis niloticus) over a 60-day period. A total of 150 juvenile Nile tilapia (Avg. wt. 9.34 ± 0.97 g) were allocated into five treatment groups: a control group (continuously fed) and four fasting groups — T1 (1‑day fasting), T2 (3‑day fasting), T3 (5‑day fasting), and T4 (7‑day fasting). Re-feeding occurred for 7 days in each group immediately following the fasting period in a recurring cycle. The average weight gain, specific growth rate, and feed efficiency ratio significantly (p < 0.05) declined starting from the T3 group. Blood glucose levels during fasting significantly decreased starting from the T2 group, but after re-feeding, they returned to levels comparable to the control group. The liver glycogen levels significantly (p ≤ 0.05) decreased during fasting and completely recovered upon re-feeding, while muscle glycogen levels did not show any significant (p ≤ 0.05) changes throughout the experimental duration. The activities of the digestive enzymes amylase and lipase significantly (p ≤ 0.05) decreased during fasting starting from T1 and T2 groups, respectively, but after re-feeding, they returned to the levels seen in the control group. In contrast, the protease enzyme levels during the fasting period initially increased up to the T2 group and subsequently returned to control levels in the T4 group. The findings of this study indicate that only the groups that experienced very short fasting periods, specifically up to the T2 group, attained body weights like the control group upon re-feeding due to compensatory growth. Therefore, this study concluded that implementing up to 3 days of fasting followed by 7 days of re-feeding in multiple cycles can serve as a strategy for minimizing input costs in tilapia farming.

There has been sustained debate for several decades, on the complex relationships between gender and science. Feminist scholars have critiqued the practices of science as being hegemonic. They trace the history of dominant practices to movements such as logical positivism. The justification for such a methodology drew from the premise that it led to the production of ​‘objective’ knowledge — true and free from human bias. However, a methodology that could be alienating for girls considering the traditional ways through which women have been socialised, could hinder the development of a ​‘science identity’. For girls who manage to continue with science in higher education, there are various other intangible barriers keeping them away from pursuing what seemed during their formative years as promising careers in science. This article presents an analysis of an assignment taken up by students in a Master’s in Education programme, as part of a course in Science Education. It required groups of students to interview a woman scientist in person and observe her working in the institution with which she is affiliated. The qualitative, thematic analysis presented multiple narratives reflecting on the role of support systems together with large challenges in overcoming perceived societal biases. However, the questions and possibilities raised by them present understanding and hope to young girls identifying with and hoping to pursue their interests in science.

Reading between the Lines: How does a mathematician do that?

The skin microbiome is mainly comprised of commensal and mutualistic bacteria. Some commensal species can behave as pathogens under the right circumstances, and one of the most common examples of this is Staphylococcus aureus. This bacterium can damage multiple parts and systems of the human body, both directly and indirectly. The factors responsible for the pathogenesis of S. aureus are discussed in this article, along with its particular role in the skin disorder atopic dermatitis, shedding light on how bacteria can use complex strategies to survive in a host.

While India has made progress in achieving important health sector goals, there is still a long way to go. The Government of India has adopted decentralization or devolution with the objective of promoting greater equity and supporting people-centred, responsive health systems. We report on a study that problematizes the idea of strengthening health sector governance through decentralization and that explores the intersection of the political goal of enhanced local-level autonomy and the programmatic goal of more responsive health service delivery. The study examines the extent to which both political and programmatic decentralization are functional at the village level; looks at the design and objectives of decentralization at the village level; and considers whether sustained and supportive capacity building can create the necessary conditions for more genuine de facto decentralization and empowerment of village-level functionaries. Our methodology included semi-structured interviews with village-level functionaries in two districts of Karnataka, based on which we designed an Action Research to strengthen coordination and synergy between the functionaries responsible for political and programmatic decentralization. We found that both political and programmatic decentralization at the village level are at risk due to a lack of convergence between the political and programmatic arms of the government. This is substantially due to problems inherent in the design of the decentralization mechanism at the district level and below. Sustained capacity building can contribute to the more effective application of decentralization mechanisms, but systemic issues regarding the decentralization mechanisms need to be addressed alongside. We were also able to identify some spaces where coordination between village-level functionaries is possible, and the steps that need to be taken to build on this potential.

This article analyses relationships between the implementation of state-level industrial policies in India and manufacturing sector economic performance (employment and gross value added), utilising data from the Annual Survey of Industries conducted by the Government of India. I employ panel data fixed-effects regression models to evaluate the associations between the industrial policy and state-industry specific performance over the 2007-08 to 2014 – 15 period, incorporating potential effects of the state government’s political alignment, infrastructure provision and educational expenditure in the state. The results provide evidence of a positive correlation between industrial policy implementation and firm output and employment, by around 12.6 — 14 per cent. However, subsequent introductions of an industrial policy are negatively associated with employment and are uncorrelated with industrial GVA. This analysis has implications for economic policy in light of the Central Government’s plans to implement a revised industrial policy at the national scale.

To contribute to the critical matter of India creating just and sustainable employment, the University has set up the Centre for Sustainable Employment (CSE), which conducts and supports research in areas of work, labour, and employment. The University is attempting to provide empirically grounded, analytical reflections on the state of work and workers in India, as well as to evaluate and propose policies that aim to create sustainable jobs. To this end the University also gives grants to create new knowledge in the above areas. It also hosts a working paper series to which contributions are invited from researchers, policy-makers, civil society actors, and journalists. The University’s CSE website is an important part of this agenda. In addition to research papers and policy briefs, it hosts government reports, as well as data and statistics on the Indian labour market. This also includes executive summary of the report.
 

State of Working India 2019 consists of labour market trends between 2016 and 2018, and four policy papers around the theme of employment generation.

Volume 7 Issue 3: The November issue has beaten the nay-sayers at their own game with articles that celebrate the joy of doing mathematics through games, stories, applications of mathematics and activities on line and in the classroom. 

Volume 6 Issue 3: The word ​‘heuristics’ has always left me fumbling for the perfect definition. Rule of thumb seems adequate but too informal, as a teacher trainer, I’ve always preferred to illustrate rather than define this word. And the first article in the November issue does just that- Gaurav Bhatnagar, leads you gently into the Exponential Series- a heuristic definition! The relaxed tone continues with V. G. Tikekar setting the stage to arrive at formulae which are usually given and proved using mathematical induction. He, on the other hand, uses the narrative mode to set the context which explains and then proves the sum of squares and sum of cubes formulae. From story we move to song, V. Ramprashanth’s article Tonic Ambiguity is a delightful depart from our usual articles and it explains very simply, using just the concepts of ratios, how two hearers can place the same tones at different positions on the musical scale. CoMaC and then Shailesh Shirali, wrap up the Features section with a bouquet of proofs.

ClassRoom opens with Prithwijit De’s trademark investigative style – the title simply says A Triangle Problem – read on to find out more. Student Corner is our happy space and this time, we have Vinay Nair’s students talking about Happy Numbers and Bodhideep Joardar Investigating Pi. Next, we have Naveen Yadav combining Set Theory, Geometry and Combinatorics in Scalene Triples and Ujjwal Rane follows up on his previous article on Fagnano’s Theorem with a very visual, very practical alternative proof. A video of this result has also been uploaded by him on YouTube, it is available at https://​youtu​.be/​5​M​r​N​M​-​VxXd8. Low Floor High Ceiling features a modification of an investigation into triangles having the same area and perimeter and conditions for congruency. Learn about G numbers in Hara Gopal’s article. We’re particularly delighted to bring in yet another new sub-section to ClassRoom – Course Correction features vignettes from pedagogical experience, ways in which pitfalls leading to misconceptions can be addressed and used to advantage to strengthen student understanding. This time, we feature the solution of a problem from a traditionally ambivalent topic- Combinatorics.

On to TechSpace, we have not one but two articles this time. Thomas Lingefjard describes the use of technology to introduce concepts in Calculus and Sangeeta Gulati describes changes in the Desmos software and how it can now be used to build activity kits. Problem Corner is a treasure trove of interesting problems in addition to the usual Middle School, Senior School and Adventures in Problem Solving articles.

Review features an old classic – R. Ramanujam takes us through a lovely guided tour of Hardy’s A Mathematician’s Apology. And there is an unexpected bonanza, with this issue, we will feature a mini- review, it may be of a video clip, a game, a story…………..all things mathematical in essence. This time, J. Shashidhar talks about Marcus du Sautoy’s Story of Mathematics. Read the facing page to know more about this fascinating mathematician.

Pullout has graduated to Upper Primary – with this issue, we bring you a compendium of information about teaching Integers- surely the point when students begin to have negative thoughts about mathematics. I’m sure you’ll enjoy reading how to combat those tendrils of fear.

Sample surveys conducted by the National Sample Survey Office (NSSO) are the most widely used sources of household level information about consumption, employment, and other socio-economic indicators in India. The representativeness of samples, the wide range of topics surveyed, and the availability of a long-time series are some of the reasons for the appeal of NSSO data for research and policy. This paper assesses the quality of the NSSO data for Nagaland and Jammu and Kashmir, which lie in India’s politically restive ethno-geographical periphery. It argues that the NSSO data for these states during 1973 – 2014 lack representativeness and inter-temporal comparability due to faulty sampling frames, frame and sample non-coverage, and biased samples. It quantifies the impact of data quality on statistics of interest to policy-makers. The paper shows that the estimates of monthly per capita consumption expenditure (MPCE) are sensitive to non-coverage and argues that the incidence of poverty is underestimated because NSSO surveys failed to capture the complete distribution of consumption expenditure due to non-coverage. In Nagaland, the degree of non-coverage was so high that in most years between 1993 – 94 and 2011-12 the state’s poverty headcount ratio was the lowest in the country despite the possible overestimation of its poverty line. The paper concludes with a discussion of the implications of the use of non-representative survey data. Put together, the unreliability of government statistics in Jammu and Kashmir and Nagaland highlights systemic problems that have wider implications for our understanding of the relationship between state, statistics, and policy-making.

The paper analyses the debates surrounding ​‘work’ as part, or as an outcome, of school education in India and argues that these have not reckoned adequately the socioeconomic reality of the corresponding times. The outcome of education depends on ideas and resources shaping its provisioning, and the use by the people. Colonial rulers provided a liberal schooling which did not aim at ​‘schooling for all’ or imparting skills as part of schooling. Such an education was attractive to those children who were not working in agriculture or artisanal occupations for their livelihood or who belonged to a ​‘rentier’ class. The lower opportunity cost of time for these children and the probability of getting a job in the colonial administration enabled this small section of society to opt for such a liberal schooling. It is in this context that Gandhi wanted to use work (or agricultural and artisanal skills) as a pedagogical tool for education. However, the majority of children who were bound to do such work then did not view formal schooling, which aimed at imparting these ​‘skills’, attractive.
