Urban greenery is a natural solution to cool cities and provide comfort, clean air and significant social, health and economic benefits. This paper aims to present the latest progress on the field of greenery urban mitigation techniques including aspects related to the theoretical and experimental assessment of the greenery cooling potential, the impact on urban vegetation on energy, health and comfort and the acquired knowledge on the best integration of the various types of greenery in the urban frame. Also to present the recent knowledge on the impact of climate change on the cooling performance of urban vegetation and investigate and analyse possible technological solutions to face the impact of high ambient temperatures.

There is nearly equal number of male and female student enrollments in primary and secondary level of education in Bangladesh, but at the tertiary level and at the job sector, a sharp drop in the number of women is observed. This paper explores the current status of female students’ enrollment in science, technology, engineering, and mathematics (STEM) at the tertiary education system in Bangladesh. It is followed by explorations of challenges women face in technical workplace. Quantitative data for the paper come from more than 1.18 million students at tertiary level from eight public and private universities for three academic years from 2018 to 2020. In addition, a qualitative study was conducted with 48 participants in pre- and during COVID-19 eras to understand barriers hampering women in STEM-related education and jobs. The paper provides a guideline for future policies to ensure inclusive space for growth and retention for women in STEM.

Abstract Macrostructural characteristics, such as cost of living and state-level anti-poverty programs relate to the magnitude of socioeconomic disparities in brain development and mental health. In this study we leveraged data from the Adolescent Brain and Cognitive Development (ABCD) study from 10,633 9-11 year old youth (5115 female) across 17 states. Lower income was associated with smaller hippocampal volume and higher internalizing psychopathology. These associations were stronger in states with higher cost of living. However, in high cost of living states that provide more generous cash benefits for low-income families, socioeconomic disparities in hippocampal volume were reduced by 34%, such that the association of family income with hippocampal volume resembled that in the lowest cost of living states. We observed similar patterns for internalizing psychopathology. State-level anti-poverty programs and cost of living may be confounded with other factors related to neurodevelopment and mental health. However, the patterns were robust to controls for numerous state-level social, economic, and political characteristics. These findings suggest that state-level macrostructural characteristics, including the generosity of anti-poverty policies, are potentially relevant for addressing the relationship of low income with brain development and mental health.

Abstract The ongoing SARS-CoV-2 pandemic has been holding the world hostage for several years now. Mobility is key to viral spreading and its restriction is the main non-pharmaceutical interventions to fight the virus expansion. Previous works have shown a connection between the structural organization of cities and the movement patterns of their residents. This puts urban centers in the focus of epidemic surveillance and interventions. Here we show that the organization of urban flows has a tremendous impact on disease spreading and on the amenability of different mitigation strategies. By studying anonymous and aggregated intra-urban flows in a variety of cities in the United States and other countries, and a combination of empirical analysis and analytical methods, we demonstrate that the response of cities to epidemic spreading can be roughly classified in two major types according to the overall organization of those flows. Hierarchical cities, where flows are concentrated primarily between mobility hotspots, are particularly vulnerable to the rapid spread of epidemics. Nevertheless, mobility restrictions in such types of cities are very effective in mitigating the spread of a virus. Conversely, in sprawled cities which present many centers of activity, the spread of an epidemic is much slower, but the responsemore »

Aktas, E. ; Bourlakis, M. (Ed.)We assess the landed costs and selected environmental outcomes of conventional field-based and representative CEA supply chains (greenhouses and plant factories) for leaf lettuce delivered to wholesale markets in two US cities. Simulation modeling using heat balance methods was used to assess CEA energy use. Landed costs of field-produced lettuce from California were less than half those from CEA systems. “Best case” analysis suggests few plausible assumptions under which urban-based CEA supply chains have landed costs comparable to field-based supply chains. Energy use and Global Warming Potential (GWP) were also generally larger for CEA supply chains, although a CEA greenhouse had only slightly higher values for GWP if located near its delivery location. Additional analysis of more automated systems in peri-urban areas is merited.
