This paper investigates one of the potential costs of rising segregation in American cities by evaluating empirically the extent at which ethnic-based segregation contributes to the onset and the speed of propagation of the COVID-19 pandemic.

Regression analysis based on matched data on early incidence of COVID-19 cases, segregation and covariates. Identification resorts on variations in segregation across MSAs and heterogeneity in the geography and timing of stay-at-home orders.

One cross-MSA standard deviation increase in segregation leads to a significant and robust rise of COVID-19 cases of 8.7 per 100,000 residents across urban counties.

Combines spatial data on COVID-19 cases and segregation; use of a new segregation measure; focus on early incidence of the pandemic and its drivers.

This study explores the social conditions for sustainability practices, addressing the processes whereby associational gardening practices in a highly segregated context may or may not create connections and capacities across urban social divides.

Based on organizational ethnographic fieldwork, the article explores urban gardens as potential meeting places in a segregated city, Gothenburg, focusing on collectively organized gardening projects in different socioeconomic and socio-spatial settings.

The study identifies the unintentional encounters embedded in the immaterial act of gardening, that is, digging, planting and actual gardening practices regardless of the harvest. Such practices were found to be important for social sustainability practices beyond the continuous reproduction of silos, at least in multicultural settings. Nevertheless, many urban gardeners create a green living room for themselves and their neighbours, and engagement with those outside their silos often becomes more of a symbolic act of global solidarity, especially in more culturally homogeneous areas.

The article fills a gap in the research by focusing on the social conditions for sustainability practices in urban segregated areas. By showing how gardening practices often reproduce cultural similarity, the study highlights the importance of revealing practices and places that facilitate unintentional social “bonus” interactions that nonetheless occur in two of the gardening environments studied. Unintentional encounters are identified as important dimensions of social sustainability practices.

This paper analyzes the differential experiences of women in the Canadian labour market who hold lower-skilled jobs and have school-age children during two waves of Covid compared with more typical conditions pre-pandemic. The article seeks to test the hypothesis that workers at the intersection of womanhood, motherhood and precarious employment would endure even more disadvantageous labour market outcomes during the Covid pandemic than they did prior to it.

We employ a Gender-Based Plus (GBA+) and intersectionality lens to examine the differential effect of Covid on the effect of the trifecta of being a woman in a lower-skilled job and facing a motherhood penalty from school-age children. We use a Difference-in-Difference framework with Canadian Labour Force Survey (LFS) data to examine the differential effect of two waves of Covid on three labour market outcomes: employment, hours worked and hourly wages.

We find that being a woman in a lower-skilled job with school-age children is associated with lower employment, hours worked and wages in normal times compared to males in those same situations. Such women also face the most severe adjustment consequence from the Covid shock, with that adjustment concentrated on the margin of employment and restricted to the First Wave and not the subsequent Omicron Wave.

The paper studies a specific intersectional group, assesses pre-pandemic, peak-pandemic and late-pandemic differences in labour market outcomes and runs separate estimations for different job skill levels. We also study a more comprehensive list of labour market outcomes than most studies of a similar nature.

Based on interviews conducted in three schools in Helsinki, Finland, I examine in this chapter 12- to 15-year-old boys' narratives about their possibilities and practices of sharing emotions in their relationships with friends and parents. I focus on how these possibilities and practices are shaped by their understanding of masculinities and ask whether these narratives continue to be shaped by hierarchising hegemonic masculine norms or if there is room for discourses and practices that depart from these norms. I argue that contradiction is a central feature in the boys' narratives of masculinities: On the one hand, the boys are critical of hegemonic masculine norms that define confiding and sharing emotions as feminine. On the other hand, they reproduce the very same norms in many discourses and everyday practices, which makes confiding and sharing emotions difficult for them.

The purpose of the study is to address concerns regarding the subjectivity and imprecision of decision-making in table tennis refereeing by developing and enhancing a sensor node system. This system is designed to accurately detect the points on the table tennis table where balls collide. The study introduces the twined-reinforcement chimp optimization (TRCO) framework, which combines two novel approaches to optimize the distribution of sensor nodes. The main goal is to reduce the number of sensor units required while maintaining high accuracy in determining the locations of ball collisions, with error margins significantly below the critical 3.5 mm cutoff. Through complex optimization procedures, the study aims to improve the efficiency and reliability of decision-making in table tennis refereeing by leveraging sensor technology.

The study employs a design methodology focused on developing a sensor array system to enhance decision-making in table tennis refereeing. It introduces the twined-reinforcement chimp optimization (TRCO) framework, combining dual adaptive weighting strategies and a stochastic approach for optimization. By meticulously engineering the sensor array and utilizing complex optimization procedures, the study aims to improve the accuracy of detecting ball collisions on the table tennis table. The methodology aims to reduce the number of sensor units required while maintaining high precision, ultimately enhancing the reliability of decision-making in the sport.

The optimization research study yielded promising outcomes, showcasing a substantial reduction in the number of sensor units required from the initial count of 60 to a more practical 49. The sensor array system demonstrated excellent accuracy in identifying the locations of ball collisions, with error margins significantly below the critical 3.5 mm cutoff. Through the implementation of the twined-reinforcement chimp optimization (TRCO) framework, which integrates dual adaptive weighting strategies and a stochastic approach, the study achieved its goal of enhancing the efficiency and reliability of decision-making in table tennis refereeing.

This study introduces novel contributions to the field of table tennis refereeing by pioneering the development and optimization of a sensor array system. The innovative twined-reinforcement chimp optimization (TRCO) framework, integrating dual adaptive weighting strategies and a stochastic approach, sets a new standard for sensor node distribution in sports technology. By substantially reducing the number of sensor units required while maintaining high accuracy in detecting ball collisions, this research offers practical solutions to address the inherent subjectivity and imprecision in decision-making processes. The study’s originality lies in its meticulous design methodology and complex optimization procedures, offering significant value to the field of sports technology and officiating.

This study takes an “entrepreneurship as emancipation” perspective to study entrepreneurs defined as “others” on multiple categories: women entrepreneurs whose ventures are necessity-based, bootstrapped and located in economically impoverished areas (neighborhoods) in two Latin-American countries: Chile and Peru.

The study takes an interpretivist research approach and analyses inductively interviews with women entrepreneurs.

The findings reveal how everyday practices in pursuit of emancipation – while conducted within the existing patriarchal social structure – push the boundaries and contribute to changes in the social system via a variety of outcomes such as intergenerational social mobility, personal fulfilment and strengthening the communities in which the women entrepreneurs operate. Furthermore, while the authors find that in the particular Latin-American context under study, entrepreneuring activities become an emancipatory possibility for the everyday women entrepreneurs, they also highlight a “dark side” of their emancipatory projects.

The study contributes to recent critical studies in entrepreneurship by demonstrating the diversity and importance of the “mundane” activities undertaken by “necessity-based” entrepreneurs, and the significant – yet underappreciated – reach of their ventures’ impact on issues well beyond economic considerations.

This paper investigates the impact of green construction procurement practices (GCPPs) on circular economy (CE) success by identifying environmentally sustainable procurement practices that can promote a CE in the construction industry. The goal was to promote circularity in construction through GCPPs.

A quantitative research approach was adopted and purposively selected 100 respondents for a cross-sectional questionnaire survey. Data from the questionnaire survey were analysed using mean score ranking, One-sample t-test and regression analysis.

The study found that using on-site systematic waste management, project stakeholder commitment and support for green practices and environmental requirements in technical specifications, significantly impact CE success in construction, with a 12.8% variance in CE when green procurement is practised. This implies that GCPPs have positive repercussions on CE success, where the CE success is expected to change as GCPPs levels increase.

The study provides insights into green procurement, promoting its use in infrastructure development and aiding clients, particularly in the government sector with insights into the challenges and practices involved in green procurement. Practitioners can also benefit from better implementing CE strategies to draft and manage contracts for infrastructure projects that prioritize circularity.

The limited impact of GCPPs on advancing CE principles in construction suggests policy and practice must strengthen procurement requirements to fully leverage spending and drive the sector’s transition towards a circular model. Also, novel insight is provided into the most effective types of GCPPs for promoting CE success, aiding policymakers in optimizing construction procurement strategies.
