The purpose of the study is to understand what impact the first COVID-19 lockdown in 2020 had on the income and food security of rural households in India and whether it differed across socioeconomic factors. Moreover, the study assesses the needs of rural households and determines whether they had received adequate support services during the lockdown.

The study adopted a repeated-measures quantitative survey design with 1,319 rural women from 16 states of India and conducted a telephonic survey.

The lockdown had directly impacted rural households' employment status and income but the impact differed depending on the type of employment. For example, working in a salaried job or on one's farm led to a lower likelihood of a complete decline in income in states other than Kerala as the lockdown continued. The study also revealed a change in the pattern of food consumption, with higher consumption of subsidized staple foods. It also became evident that the aid announced by the government reached the rural population with some delay.

A limitation of the study was that many respondents refused to participate in phase 2, which reduced the sample size when comparing the two phases because the women did not own mobile phones. Instead, they were using their husbands' phones.

The study's findings can help better understand the needs of rural populations during crises, such as the COVID-19 pandemic. This can help to plan better and build preventive actions for such populations once their needs are understood. In addition, this can aid disadvantaged people for a minimal level of preparedness and security during such a crisis in the future.

The purpose of this study is to investigate the motivations and barriers behind the adoption of bike-sharing services, explore the influence of individual values and environmental knowledge on bike-sharing adoption and analyze the relationship between reasons, attitude and intention to utilize bike-sharing.

The study initially conducted a semi-structured interview with 19 bike-sharing users and performed a thematic analysis to identify the context-specific motivators and barriers. The identified factors were then incorporated into the behavioral reasoning theory (BRT) framework and quantitatively examined using the data gathered from 412 Indian bike-sharing users.

The findings outlined the complex reasoning process underlying bike-sharing adoption and how environmental value and attitude are related to the reasons. Further, the study examined the moderating impact of environmental knowledge, which was overlooked in previous studies.

The study provides valuable suggestions to bike-sharing businesses, which helps them to induce facilitators and remove barriers.

Behavioral research in bike-sharing is in its embryonic stage. This is one of the initial attempts to address this knowledge deficit by comprehensively examining the factors affecting bike-sharing intention through the theoretical lens of BRT.

Identity exploration is a central mechanism for identity formation that has been found to be associated with intense engagement, positive coping, openness to change, flexible cognition, and meaningful learning. Moreover, identity exploration in school has been associated with adaptive motivation for learning the academic material. Particularly in the fast-changing environment of contemporary society, confidence and skills in identity exploration and self-construction seems to be increasingly important. Therefore, promoting students’ identity exploration in school within the curriculum and in relation to the academic content should be adopted as an important educational goal. The purpose of this paper is to describe a conceptual framework for interventions to promote students’ identity exploration within the curriculum. The framework involves the application of four interrelated principles: (1) promoting self-relevance; (2) triggering exploration; (3) facilitating a sense of safety; and (4) scaffolding exploratory actions.

We begin the paper with a conceptual review of identity exploration. We follow by specifying the conceptual framework for interventions. We then present a methodological-intervention approach for applying this framework and describe three such interventions in middle-school contexts, in the domains of environmental education, literature, and mathematics.

In each intervention, applying the principles contributed to students’ adaptive motivation and engagement in the academic material and also contributed to students’ identity exploration, though not among all students. The findings highlight the contextual, dynamic, and indeterminate nature of identity exploration among early adolescents in educational settings, and the utility of the conceptual framework and approach for conceptualizing and intervening to promote identity exploration among students.

This paper contributes to the conceptual understanding of identity exploration in educational settings, highlights the benefits and the challenges in intervening to promote identity exploration among students, and discusses the future directions in theory, research, and practice concerned with the promotion of identity exploration in educational settings.

My early life was punctuated by turning points and transformations that gradually led to a surprising and late-blooming academic career – my first “real” sociology position began when I was 44. Here I trace six different trajectories of scholarly work which have compelled me: feminist women's health and technoscience studies; social worlds/arenas and the disciplinary emergence of reproductive sciences; the sociology of work and scientific practices; biomedicalization studies; grounded theory and situational analysis as qualitative research methods; and symbolic interaction-ists and -isms. I have circled back across them multiple times. Instead of seeing a beautifully folded origami of a life, it feels more like a crumpled wad of newspapers from various times. Upon opening and holding them up to the light in different ways, stories may be slowly discerned. I try to capture here some of the sweetness and fragility of these moments toward the end of an initially stuttering but later wondrously gratifying career.

The aim of this paper is the study of the magnetic separation of pollutants from water by means of a magnetic filter. A magnetic activated carbons nanometric powder that combines the well-known pollutants absorbent capacity of activated carbons with the magnetic properties of magnetite (Fe₃O₄) is used.

The considered magnetic filter is made of stainless steel spheres, magnetized by an external flux density field provided by permanent magnets. Flux density and fluid velocity fields are evaluated using volume integral equation method. The modelling of the particles trajectories inside the filter allows calculating its capture efficiency.

The results of the model are tested on the experimental data obtained using two different setups. A removal of the powder larger than 90 percent is achieved in both cases. The pollutant removal efficiency is checked on surfactants (water diluted). Their adsorption on magnetic activated carbons leads to residual concentration below the limit for the reuse in agriculture (according to the Italian legislation) for all the tested surfactants.

The proposed process combines efficiently a physico-chemical phase of adsorption and a magnetic phase of filtration due to the particular properties of magnetic activated carbons.
