Housing Insecurity Among Black Women Surviving Intimate Partner Violence During The Covid-19 Pandemic: An Intersectional Qualitative Approach, Tiara C. Willie, Sabriya L. Linton, Shannon Whittaker, Karlye A. Phillips, Deja Knight, Mya C. Gray, Gretta Gardner, Nicole Overstreet

Psychology

Background: Housing instability is highly prevalent among intimate partner violence (IPV) survivors, and the coupling consequences of structural racism, sexism, classism, and the COVID-19 pandemic, may create more barriers to safe and adequate housing, specifically for Black women IPV survivors. In particular, the consequences of the COVID-19 pandemic had the potential to amplify disadvantages for Black women IPV survivors, yet very little research has acknowledged it. Therefore, the current study sought to assess the experiences of housing insecurity among Black women experiencing intimate partner violence (IPV) while navigating racism, sexism, and classism during the COVID-19 pandemic. Methods: From January to …

The Journey To Project Management: Navigating The Transition From A Nonproject Environment, Renate Lian Mascarenhas, Shagun Verma, Shrishti Rana

School of Professional Studies

To facilitate a seamless transition from a non-project management environment to a project management environment, Non-Profit Organizations (NPOs) passionately dedicated to their missions and operating with limited resources can establish a Project Management Office (PMO) as a pivotal organizational function. This PMO will collaborate closely with senior executives to devise a comprehensive strategic plan for this transformation. An essential component of this plan is the identification of dedicated representatives within key departments, including IT, HR, Human Services Program, and Learning & Development. These departmental representatives will serve as proactive Project Management advocates, responsible for initiating and executing the transition strategies, …


The Effect Of Crime On Mental Health In South Africa, Magda Tsaneva, Lauren-Kate Laplante May 2024

The Effect Of Crime On Mental Health In South Africa, Magda Tsaneva, Lauren-Kate Laplante

Economics

This paper examines the impact of district-level crime rates in South Africa on individual depression symptoms. We use panel data from the National Income Dynamics Survey collected between 2008 and 2014 and estimate an individual fixed effects regression model, thus controlling for characteristics of the individual's environment that could affect crime and mental health. We find that an increase of one standard deviation in property (violent) crime is associated with a 7.2 (8.7) percentage point increase in the probability of depression symptoms. Analysis of potential mechanisms suggests that indirect exposure to crime likely affects mental health by increasing stress rather …

Political Science

Climate change will shape the future of Russia, and vice versa, regardless of who rules in the Kremlin. The world's largest country is warming faster than Earth as a whole, occupies more than half the Arctic Ocean coastline, and is waging a carbon-intensive war while increasingly isolated from the international community and its efforts to reduce greenhouse gas emissions. Officially, the Russian government argues that, as a major exporter of hydrocarbons, Russia benefits from maintaining global reliance on fossil fuels and from climate change itself, because warming may increase the extent and quality of its arable land, open a new …

Patterns Of Infringement, Risk, And Impact Driven By Coal Mining Permits In Indonesia, Tim T. Werner, Tessa Toumbourou, Victor Maus, Martin C. Lukas, Laura J. Sonter, Muhamad Muhdar, Rebecca K. Runting, Anthony J. Bebbington

Geography

Coal mining is known for its contributions to climate change, but its impacts on the environment and human lives near mine sites are less widely recognised. This study integrates remote sensing, GIS, stakeholder interviews and extensive review of provincial data and documents to identify patterns of infringement, risk and impact driven by coal mining expansion across East Kalimantan, Indonesia. Specifically, we map and analyse patterns of mining concessions, land clearing, water cover, human settlement, and safety risks, and link them with mining governance and regulatory infractions related to coal mining permits. We show that excessive, improper permit granting and insufficient …

Geography

Highlights

  • Mining-induced displacement is a severely under researched social policy problem.
  • Through global data sources and historic remote sensing we analyze this problem.
  • The main output of most mining activity is hazardous waste.
  • We confirm waste as the principal source of human displacement globally in mining.
  • Resources to fuel urbanisation and energy transition targets will drive increases in waste.

Ethiopians have deep-rooted traditions of using plants to treat ailments affecting humans and domesticated animals. Approximately 80% of the population continues to rely on traditional medicine, including for the prevention and treatment of viral diseases. Many antiviral plants are available to and widely used by communities in areas where access to conventional healthcare systems is limited. In some cases, pharmacological studies also confirm the potent antiviral properties of Ethiopian plants. Building on traditional knowledge of medicinal plants and testing their antiviral properties may help to expand options to address the global pandemic of COVID-19 including its recently isolated virulent variants …

Improvements In Depressive Symptoms Following A Brief Relationship Intervention, Erica A. Mitchell, Patricia N.E. Roberson, Michaela Dipillo, James V. Cordova, Kristina Coop Gordon

Psychology

In the United States, 21 million adults are diagnosed with depression. Couple therapy effectively treats depression, however, couples encounter access barriers. The Relationship Checkup is an assessment and feedback intervention delivered in participants' homes. The current study examines changes in relationship satisfaction and depressive symptoms, and moderators and mechanisms of change in a community sample (N = 85 couples). Changes in depressive symptoms and satisfaction, and the association between changes in satisfaction and depressive symptoms were examined with multilevel modeling. Depressive symptoms (Cohen's d = 0.36) and satisfaction (d = 1.43) improved from baseline to 1-month follow-up, with greater declines …

Sustainability and Social Justice

Background: Manganese (Mn) is a metal commonly found in drinking water, but the level that is safe for consumption is unknown. In the United States (U.S.), Mn is not regulated in drinking water and data on water Mn concentrations are temporally and spatially sparse. Objective: Examine temporal and spatial variability of Mn concentrations in repeated tap water samples in a case study of Holliston, Massachusetts (MA), U.S., where drinking water is pumped from shallow aquifers that are vulnerable to Mn contamination. Methods: We collected 79 residential tap water samples from 21 households between September 2018 and December 2019. Mn concentrations …


Bridging And Breaking Silos: Transformational Governance Of The Migration–Sustainability Nexus, Caroline Zickgraf, Dominique Jolivet, Claudia Fry, Emily Boyd, Anita Fabos Jan 2024

Bridging And Breaking Silos: Transformational Governance Of The Migration–Sustainability Nexus, Caroline Zickgraf, Dominique Jolivet, Claudia Fry, Emily Boyd, Anita Fabos

Sustainability and Social Justice

Sustainability and migration are typically treated as discrete policy spheres in inter-national, national, and local fora, separated in governance structures and institutions. This results in policy incoherence that hinders just transitions toward more sustainable societies cognizant of mobile realities. This explorative effort identifies the (dis)connec-tions between policy domains using data collected on how the sustainability–migration nexus is governed in four countries with a special emphasis on urban areas: Belgium, the Netherlands, Sweden, and the United States. Results of 73 interviews show that migration and sustainability actors find it challenging to see how they could be working together and that migrants …

Priest, Florencia Sangermano, Allison Bailey, Victoria Bugni, María Del Carmen Villalobos-Segura, Nataly Pimiento-Quiroga, Peter Daszak, Carlos Zambrana-Torrelio

Geography

Indigenous territories are considered important for conservation, but little is known about their role in maintaining human health. Here we quantified the potential human health and economic benefits of protecting these territories in the Brazilian Amazon, by using cardiovascular and respiratory diseases cases, pollutant and forest cover data. Between 2010 and 2019, 1.68 tons of Particulate Matter of small size (PM2.5) were released every year, with negative effects for human health. A lower number of infections was also found in municipalities with more forested areas, and with a low level of fragmentation, which probably is related to the …


Examining Current Bias And Future Projection Consistency Of Globally Downscaled Climate Projections Commonly Used In Climate Impact Studies, Lucas Berio Fortini, Lauren R. Kaiser, Abby Frazier, Thomas W. Giambelluca Dec 2023

Examining Current Bias And Future Projection Consistency Of Globally Downscaled Climate Projections Commonly Used In Climate Impact Studies, Lucas Berio Fortini, Lauren R. Kaiser, Abby Frazier, Thomas W. Giambelluca

Geography

The associated uncertainties of future climate projections are one of the biggest obstacles to overcome in studies exploring the potential regional impacts of future climate shifts. In remote and climatically complex regions, the limited number of available downscaled projections may not provide an accurate representation of the underlying uncertainty in future climate or the possible range of potential scenarios. Consequently, global downscaled projections are now some of the most widely used climate datasets in the world. However, they are rarely examined for representativeness of local climate or the plausibility of their projected changes. Here we explore the utility of two …

Mi Casa Sin Mí Parada No Es Casa: Conceptualizations Of Functioning And Functional Impairment In Rural Chiapas, Mexico, Sarah Joy Hartman, Néstor Noyola, Viena Murillo, Fátima Rodríguez Cuevas, Esteban V. Cardemil

Psychology

In mental healthcare, functional impairment is an essential element in diagnosing and monitoring the severity of mental disorders. However, current clinical practices do not account for how context and culture might shape conceptions of functional impairment, given the demonstrated influence of cultural context on mental health, particularly in Mexico. We interviewed 16 members of a rural community in Chiapas, Mexico to understand how they understood functioning and how functioning is impacted by distress. We analyzed the data using thematic analysis with a critical lens. With regards to conceptions of functioning, participants described that to function was to work (nuestra vida …


How Social Structure Shapes Female Competition Throughout Her Lifetime, Jeffrey Flory, Kenneth L. Leonard, Magda Tsaneva, Kathryn Vasilaky Dec 2023

How Social Structure Shapes Female Competition Throughout Her Lifetime, Jeffrey Flory, Kenneth L. Leonard, Magda Tsaneva, Kathryn Vasilaky

Economics

Many studies find a consistent gender gap in competitiveness where men are more likely to compete than women given the same level of ability. Using data from experiments with women ages 12 through 90 in matrilocal and patrilocal communities in rural Malawi, we show that this gender gap does not exist uniformly for all women nor across their whole lifetime. We first replicate three main findings from the gender and competition literature: (i) women are less likely to compete on average; and the gender gap differs by (ii) culture and by (iii) age. In a new finding, we show that …

Sustainability and Social Justice

Research on the impacts of COVID-19 on mobility has focused primarily on the increased health vulnerabilities of involuntary migrant and displaced populations. But virtually all migration flows have been truncated and altered because of reduced economic and mobility opportunities of migrants. Here we use a well-established framework of migration decision-making, whereby individual decisions combine the aspiration and ability to migrate, to explain how public responses to the COVID-19 pandemic alter migration patterns among urban populations across the world. The principal responses to COVID-19 pandemic that affected migration are: 1) through travel restrictions and border closures, 2) by affecting abilities to …

Economics

Significance statement:
The paper presents major new insights into the multidisciplinary controls of nitrogen export (a widespread environmental concern) from residential landscapes. We conducted biogeochemical and social survey studies to identify locations (hotspots) or times (hot moments) with a disproportionate influence on this export. Results showed high variation in the vulnerability/sensitivity of individual parcels to cause environmental damage and in the knowledge and practices of individual managers. To the extent that hotspots are the result of management choices by homeowners, there are straightforward approaches to improve outcomes, e.g. fertilizer restrictions. If, however, hotspots arise from the configuration and inherent characteristics …

In Africa, "Climate-Smart" Conservation Must Be Coupled With Poverty Alleviation, Saleem H. Ali, Penda Diallo, Apoli Bertrand Kameni, Philippe Le Billon, Kopo Oromeng, Kyle Frankel Davis, Edward Carr

Geography

In August, the Seventh Assembly of the Global Environment Facility (GEF) concluded in Vancouver, Canada, with a pledge. A total of 185 countries agreed to protect 30% of land and coastal areas by 2030 (known as the “30 by 30 pledge”). But while this surge of conservation funding is heartening, there are serious concerns. Projects and programs that appear to produce both environmental and developmental goals could actually obscure the continuing marginalization of poor and vulnerable populations. Here, we suggest that such coupling of conservation and extraction needs to pay greater attention to poverty alleviation. Otherwise, it risks further marginalizing …


Structural Tensions Limiting Success Of Infrastructure Upgrading: A Multi-Regime Perspective, George Kiambuthi Wainaina, Bernhard Truffer, James T. Murphy Sep 2023

Structural Tensions Limiting Success Of Infrastructure Upgrading: A Multi-Regime Perspective, George Kiambuthi Wainaina, Bernhard Truffer, James T. Murphy

Geography

Unfettered growth of slums is a daunting transition challenge and many upgrading programs fail to sustainably improve the livelihoods of slum residents. This paper elaborates a transitions perspective on structural tensions that may lead to success or failure of slum upgrading programs. We conceptualize slums as urban subsystems, governed by sociotechnical (infrastructure) and socioeconomic livelihood regimes (related to production and social reproduction). The framework permits examination of the tensions due to mis/alignments of rules associated with newly introduced infrastructures, and those that regulate existing production and social reproduction practices of slum residents. This approach extends transition studies by accounting for …

Improved Fine-Scale Tropical Forest Cover Mapping For Southeast Asia Using Planet-Nicfi And Sentinel-1 Imagery, Feng Yang, Xin Jiang, Alan D. Ziegler, Lyndon Estes, Jin Wu, Anping Chen, Philippe Ciais

Geography

The accuracy of existing forest cover products typically suffers from “rounding” errors arising from classifications that estimate the fractional cover of forest in each pixel, which often exclude the presence of large, isolated trees and small or narrow forest clearings, and is primarily attributable to the moderate resolution of the imagery used to make maps. However, the degree to which such high-resolution imagery can mitigate this problem, and thereby improve large-area forest cover maps, is largely unexplored. Here, we developed an approach to map tropical forest cover at a fine scale using Planet and Sentinel-1 synthetic aperture radar (SAR) imagery …

Assessing The Impacts Of Increasing The Availability Of Non-Automobile Modes Of Transportation On Carbon Emissions And Accessibility In Worcester, William Schechter

Sustainability and Social Justice

Over-reliance on cars in Worcester, Massachusetts represents a significant barrier to the introduction of accessible and ecologically sound modes of transportation. Through increases in frequency, accessibility, and service area, bus transportation in Worcester can offer a viable alternative to personal vehicle usage. In conjunction with the changes to buses, improvements to infrastructure for non-motorist transportation modes such as cycling, walking and assistive equipment will further reduce reliance on personal motor vehicles. Additional policies discouraging the use of motor vehicles is also suggested, with limited traffic zones and vehicle weight restrictions being implemented. With the developments and policy outlined within this …

The Flow Matrix Offers A Straightforward Alternative To The Problematic Markov Matrix, Jessica Stzempko, Robert Gilmore Pontius Jul 2023

The Flow Matrix Offers A Straightforward Alternative To The Problematic Markov Matrix, Jessica Stzempko, Robert Gilmore Pontius

Geography

The Flow matrix is a novel method to describe and extrapolate transitions among categories. The Flow matrix extrapolates a constant transition size per unit of time on a time continuum with a maximum of one incident per observation during the extrapolation. The Flow matrix extrapolates linearly until the persistence of a category shrinks to zero. The Flow matrix has concepts and mathematics that are more straightforward than the Markov matrix. However, many scientists apply the Markov matrix by default because popular software packages offer no alternative to the Markov matrix, despite the conceptual and mathematical challenges that the Markov matrix …

Psychology

Emerging adulthood (EA) is a critical stage of life to develop and sustain a healthy lifestyle, which is also a time of vulnerability to poor physical and mental health outcomes. In this study, we conducted a path analysis (N = 1326) to examine associations among four dimensions of EA, levels of regular physical activity (PA), self-control, MPA tendency and irrational procrastination. Results found: 1) higher levels of PA predicted both MPA tendency (β = −0.08, 95% CI: −0.11 to −0.06, p < 0.001) and irrational procrastination (β = −0.01, 95% CI: −0.17 to −0.008, p < 0.01) indirectly via self-control; 2) Instability (β = 0.13, 95% CI: 0.08 to 0.18, p < 0.01) and Responsibility (β = −0.06, 95% CI: −0.10 to −0.08, p = 0.03) exerted direct effects on irrational procrastination and Instability also indirectly predicted irrational procrastination via MPA tendency (β = 0.03, 95% CI: 0.02 to 0.05, p < 0.01). These findings proved that perceived features of EA are linked to behavioral problems and supported that regular PA plays a crucial role to protect mental health. © 2023, Tech Science Press.

Is Closing The Agricultural Yield Gap A "Risky" Endeavor?, Nicolas Gatti, Michael Cecil, Kathy Baylis, Lyndon Estes, Jordan Blekking, Thomas Heckelei, Noemi Vergopolan, Tom Evans

Geography

CONTEXT: Sub-Saharan Africa (SSA) has the climatic and biophysical potential to grow the crops it needs to meet rapidly growing food demand; however, agricultural productivity remains low. While potential maize yields in Zambia are 9 t per hectare (t/ha), the average farmer produces only 1–2. OBJECTIVE: We evaluate the contribution of responses to weather risk to that gap by decomposing the yield gap in maize in Zambia. While we know that improved seed and fertilizer can expand yield and profit, they may also increase the variance of yield under different weather outcomes, reducing their adoption. METHODS: We use a novel …


Limited Evidence Of Cumulative Effects From Recurrent Droughts In Vegetation Responses To Australia's Millennium Drought, Tong Jiao, Christopher A. Williams, Martin De Kauwe, Belinda E. Medlyn May 2023

Limited Evidence Of Cumulative Effects From Recurrent Droughts In Vegetation Responses To Australia's Millennium Drought, Tong Jiao, Christopher A. Williams, Martin De Kauwe, Belinda E. Medlyn

Geography

Drought-induced vegetation declines have been reported across the globe and may have widespread implications for ecosystem composition, structure, and functions. Thus, it is critical to maximizing our understanding of how vegetation has responded to recent drought extremes. To date, most drought assessments emphasized the importance of drought intensity for vegetation responses. However, drought timing, duration, and repeat exposure all may be important aspects of ecosystem response with the potential for non-linear effects. Cumulative effects are one such phenomenon, representing the additional decline due to repeated exposure to drought, and indicating gradual loss of ecosystem resistance. This study quantifies the frequency …
