Student Food Security Status at Virginia Tech: Virginia Tech Food Access and Wellbeing Survey
Holmes, Chanita; Hall, Ralph; Misyak, Sarah; Olayemi, Victor (Virginia Cooperative Extension, 2024-10-02)
There has been a growing acknowledgment and concern about college students experiencing food insecurity at institutions of higher education [1]. Experiencing food insecurity can impact educational attainment and performance as well as student quality of life [2]. This report describes the findings of the 2023 Virginia Tech Student Food Access and Wellbeing Survey, which was administered online during the Spring of 2023. The survey aimed to examine the level of food security among Virginia Tech undergraduate and graduate students.
Read all about it: Examining newspaper coverage of the local environmental risks posed by the Radford Army Ammunition Plant
Seo, Hye-Jeong; Schenk, Todd (Routledge, 2023-03-27)
This study examines the factors contributing to the inclusion of scientific information in local news coverage of environmental risks. We conducted a content analysis of articles about environmental issues associated with the Radford Army Ammunition Plant, Virginia’s largest point source of toxic chemical releases. We coded 116 articles published between 2000 and 2019 according to three criteria: the inclusion of scientific information, who is making claims, and whether or not explicit risks are identified. Only 35.3% of the articles reviewed include scientific information. Logistic regression indicates that when an article includes claims made by state officials and/or explicitly asserts the existence of environmental risks, it is more likely to include scientific information. Articles that include claims from community activists are less likely to include scientific information. We examine potential explanations for these patterns.
Health Worker Potential for Expanded Exploration of Public “Frontlineness”: A Scientometric Analysis
Bredenkamp, David M.; Abdelrasol, Saif Tarek; Boyette, Charity L.; Comer, C. Cozette; Stovall, Connie; Talukdar, Shahidur Rashid (2024-06-28)
Public-sector frontline service scholarship in the field of public administration has been conducted under relatively limited circumstances and contexts. While literature focusing on the topic has been prolific, the context and lenses through which “frontlineness” has been viewed and observed are more limited (Chang & Brewer 2022). The scholarship on street-level bureaucrats (SLBs) has focused on a well-defined, though narrow, set of workers and work environments (e.g., teachers and nurses; schools and hospitals); those concentrated and consistent parameters may present an opportunity for greater generalizability of our understanding of SLBs than previously realized. We seek something of a new beginning: for theoretical exploration, clarity, and eventual reassessment of what frontlineness is and what it means. Healthcare has been a field in which public administration scholars have—either adjacently or directly—explored the nature of frontline work. We hypothesize, however, that there is much territory that goes unexplored due to siloing of disciplines, narrow definitions of what it means to be on the “frontline,” and more limited use in public administration scholarship of available evidence synthesis methods. One such method, scientometric analysis, provides useful tools to explore the potential of fields such as healthcare, with its results providing the “lay of the land” for further exploration. Using a scientometric analytical approach, this paper offers an answer to the following research question: What is the potential for existing research to describe the proximal relationship between a frontline healthcare employee and the frontline itself?
"There Should Be No Life": Environmental Perspectives on Genocide in Northern Iraq
Ahram, Ariel I. (Routledge, 2023-09-07)
This article examines the natural environment during the Kurdish genocide in northern Iraq. The genocide killed between 50,000 and 180,000 people and destroyed some 4,500 Kurdish villages from the 1960s to 1980s, reach peak violence during the Iran-Iraq War (1980–88). The paper uses American, British, and Iraqi archival documents to analyse how the violence affected the natural landscape and how ecological conditions constrained the violence. Iraqi leaders regarded dams and other modes of environmental engineering as levers to facilitate agricultural modernization and social integration. Protecting and projecting hydraulic power justified greater military exertion. Iraqi leaders, frustrated by the lack of progress in development and hostile to the claims of Kurdish nationalism, resorted to more coercive options to combat guerrillas. But the inadequacies of military exertion prompted the government to redouble efforts to tame unruly nature and those who dwelled in it. This escalation contributed significantly to the lethal violence against rural Kurdish society. At a theoretical level, these findings highlight the troubling ways in which policies aimed to improve environmental conditions fold into campaigns of mass violence. The article also adds to understanding of violence in Iraq, showing how Iraq’s attempts to use environmental engineering for development intersected with security concerns and ethnic marginalization to create more intensive repression.
In Search of a Middle East and North Africa Peace System
Ahram, Ariel I. (SAGE Publications, 2024-04-11)
This article examines the strengths and weaknesses of the peace system in the Middle East and North Africa (MENA). It views peace not merely as the absence of direct violence but as the result of institutions and systems that mitigate, defuse, and diminish conflict. The peace system of MENA operates at multiple scales and deals with multiple kinds of violent conflict. Different system components produce different forms of positive and negative peace through both formal and informal institutional channels. Consequently, peace in MENA is often uneven and unstable, with progress in one dimension coming at the expense of another. Understanding the gaps and inconsistencies within the MENA peace system can help devise a more realistic and feasible approach to conflict resolution rather than abstract and ultimately impractical ideals. The article identifies shortcomings in the current explanations for the frequency of war, explores the idea of a regional peace system that operates in regional and domestic arenas both formally and informally, and examines policy measures that might bolster or undercut the MENA peace system.
Mobilizing in Uncertainty: Collective Identities and War in Abkhazia [Book review]

Can Common Pool Resource Theory Catalyze Stakeholder-Driven Solutions to the Freshwater Salinization Syndrome?
Grant, Stanley B.; Rippy, Megan A.; Birkland, Thomas A.; Schenk, Todd; Rowles, Kristin; Misra, Shalini; Aminpour, Payam; Kaushal, Sujay; Vikesland, Peter J.; Berglund, Emily; Gomez-Velez, Jesus D.; Hotchkiss, Erin R.; Perez, Gabriel; Zhang, Harry X.; Armstrong, Kingston; Bhide, Shantanu V.; Krauss, Lauren; Maas, Carly; Mendoza, Kent; Shipman, Caitlin; Zhang, Yadong; Zhong, Yinman (American Chemical Society, 2022-09-14)
Freshwater salinity is rising across many regions of the United States as well as globally, a phenomenon called the freshwater salinization syndrome (FSS). The FSS mobilizes organic carbon, nutrients, heavy metals, and other contaminants sequestered in soils and freshwater sediments, alters the structures and functions of soils, streams, and riparian ecosystems, threatens drinking water supplies, and undermines progress toward many of the United Nations Sustainable Development Goals. There is an urgent need to leverage the current understanding of salinization's causes and consequences?in partnership with engineers, social scientists, policymakers, and other stakeholders?into locally tailored approaches for balancing our nation's salt budget. In this feature, we propose that the FSS can be understood as a common pool resource problem and explore Nobel Laureate Elinor Ostrom's social-ecological systems framework as an approach for identifying the conditions under which local actors may work collectively to manage the FSS in the absence of top-down regulatory controls. We adopt as a case study rising sodium concentrations in the Occoquan Reservoir, a critical water supply for up to one million residents in Northern Virginia (USA), to illustrate emerging impacts, underlying causes, possible solutions, and critical research needs.

Homefront to Battlefront: Why the U.S. Military Should Care About Biomedical Cybersecurity
Brantly, Nataliya D. (Army Cyber Institute, 2021-04-01)
Immunity to the cybersecurity risks and potential hazards presented using biomedical devices. US Military and civilian personnel use these devices on the Homefront and battlefield. As the use of biomedical devices increases with time and blurs the lines between private and professional, more attention is required of the U.S. Department of Defense (DoD) to understand the strategic importance of securing biomedical devices. This work provides a better understanding of biomedical devices and analyzes current use of biomedical devices within DoD. It also provides recommendations on actions DoD can undertake to safeguard its workforce today and in the near future. This article examines the significance of cybersecurity for biomedical devices within the context of US national security and demonstrates the important role biomedical cybersecurity plays for DoD.
The landscape and evolution of urban planning science
Haghani, Milad; Sabri, Soheil; De Gruyter, Chris; Ardeshiri, Ali; Shahhoseini, Zahra; Sanchez, Thomas W.; Acuto, Michele (Elsevier, 2023-05)
The science of urban planning has drawn on a wide range of disciplines and research perspectives. This makes it challenging to define the boundaries and directions of the field. Here, nearly 100,000 articles on urban planning are analysed to objectively determine divisions, temporal trends and influential references and actors of urban planning. In terms of the structural composition, four broad divisions are identified: (1) governance and policy, (2) economics and markets, (3) housing and (4) built and natural environment. In terms of the temporal evo-lution, the earliest trends were related to "welfare economics", "agglomeration economies", "urban economics", and "urban growth machine". During the 1980s and 1990s, the focus moved towards "regional policy and development", "social welfare", and "urban renaissance". This trend continued during the 2000s and 2010s, heading to "urban morphology", "participatory planning", "urban sociology", "global cities", and "political economy". The field has recently headed towards areas of "resilience", "smart cities" and "urban green space". These transitions have been derivative, and the paradigm shifts have been very gradual. Another key observation is a notable increase in author connectivity and international collaboration. The results provide objective insights into how the science of urban planning has historically transitioned and where it is headed.
Where theory and practice meet: Good government, merit-based civil service, and HRM courses
Guy, Mary E.; Mastracci, Sharon (Routledge, 2023-03)
MPA programs are the only place where public sector human resource management (HRM) is taught. When HRM is not among the list of required courses, programs forgo their responsibility to teach the next generation of public servants why merit-based civil service is crucial to a functioning democracy. The danger of ignorance is reflected in an Executive Order issued in 2020 that would have removed job protections from thousands of federal civil servants. While the Order was rescinded in 2021, it has many advocates and remains on the agenda. This is a wake-up call to MPA programs to require students to learn why job protections are the bedrock of good government, a bedrock as foundational as a free press and more foundational than budgeting skills. However, 97% of MPA programs require a budgeting course but only 72% require an HRM course. If theory and practice meet in MPA classrooms, then HRM has to be there.
Planning on the Verge of AI, or AI on the Verge of Planning
Sanchez, Thomas W. (MDPI, 2023-06-28)
The urban planning process is complex, involving social, economic, environmental, and political systems. Knowledge of how these systems interact is the domain of professional planners. Advances in artificial intelligence (AI) present planners with a ripe opportunity to critically assess their approaches and explore how new data collection, analysis, and methods can augment the understanding of places as they seek to anticipate futures with improved quality of life. AI can offer access to more and better information about travel patterns, energy consumption, land utilization, and environmental impacts, while also helping to better integrate these systems, which is what planners do. The adoption process will likely be gradual and involve significant time and resources. This article highlights several topics and issues that should be considered during this process. It is argued that planners will be well-served by approaching AI tools in a strategic manner that involves the topics discussed here.
Portfolio management: A new direction in public sector strategic management research and practice
Roberts, Patrick S.; Edwards, Lauren Hamilton (Wiley, 2023-05)
Portfolio management is widely used by large government agencies and nonprofits, but it is rarely discussed in public administration scholarship. Portfolio management tools can illuminate groups of projects that should be considered as priority investments by highlighting the relationship of risk to outcomes. This article explores historical and theoretical reasons for the neglect of portfolio management, and then proposes using portfolio management to update a classic strategic management framework to guide organizational choices in public administration. Though portfolio management ideas originated in the private sector, public sector portfolio management differs from its private sector counterpart by trading off risk with public value or mission outcomes rather than financial outcomes. Portfolio management is a tool to incorporate risk to mission in investment decisions. It holds promise for adding an intermediate-level implementation tool to develop theories of public value. The paper concludes with hypotheses for future investigation.
Comparison of different spatial temperature data sources and resolutions for use in understanding intra-urban heat variation
Kianmehr, Ayda; Lim, Theodore C.; Li, Xiaojiang (Elsevier, 2023-09)
In this study, we investigate the compatibility of specific vulnerability indicators and heat exposure data and the suitability of spatial temperature-related data at a range of resolutions, to represent spatial temperature variations within cities using data from Atlanta, Georgia. For this purpose, we include various types of known and theoretically based vulnerability indicators such as specific street-level landscape features and urban form metrics, population-based and zone-based variables as predictors, and different measures of temperature, including air temperature (as vector-based data), land surface temperature (at resolution ranges from 30 m to 305 m), and mean radiant temperature (at resolution ranges from 1 m to 39 m) as dependent variables. Using regression analysis, we examine how different sets of predictors and spatial resolutions can explain spatial heat variation. Our findings suggest that the lower resolution of land surface temperature data, up to 152 m, and mean radiant temperature data, up to 15 m, may still satisfactorily represent spatial urban temperature variation caused by landscape elements. The results of this study have important implications for heat-related policies and planning by providing insights into the appropriate sets of data and relevant resolution of temperature measurements for representing spatial urban heat variations.
Civil society priorities for global health: concepts and measurement
Smith, Stephanie L. (Oxford University Press, 2023-05-22)
The global health agenda--a high stakes process in which problems are defined and compete for the kind of serious attention that promises to help alleviate inequities in the burden of disease--is comprised of priorities set within and among a host of interacting stakeholder arenas. This study informs crucial and unanswered conceptual and measurement questions with respect to civil society priorities in global health. The exploratory two-stage inquiry probes insights from experts based in four world regions and pilots a new measurement approach, analysing nearly 20 000 Tweets straddling the COVID-19 pandemic onset from a set of civil society organizations (CSOs) engaged in global health. Expert informants discerned civil society priorities principally on the basis of observed trends in CSO and social movement action, including advocacy, program, and monitoring and accountability activities-all of which are widely documented by CSOs active on Twitter. Systematic analysis of a subset of CSO Tweets shows how their attention to COVID-19 soared amidst mostly small shifts in attention to a wide range of other issues between 2019 and 2020, reflecting impacts of a focusing event and other dynamics. The approach holds promise for advancing measurement of emergent, sustained and evolving civil society priorities in global health.
Does the economic DNA of the city exist?
Manthapuri, Sadhana; Hall, Ralph P. (Elsevier, 2023-05)
Local economic development (LED) is a place-based planning approach. Global best practices and research focus on different contemporary marketing strategies to harness local resources for economic growth. The theoretical evolution of LED can be divided into two categories: the era before and the era after the emergence of sustainable and smart development. Many theories developed during these eras had themes/components focused on advancing LED, with each theory contributing a new idea to understanding the existing local economic structure. This research focuses on the contributions of, and connections between, different economic theories with the ambition of creating a comprehensive understanding of local economic structure. This paper advances ‘Economic DNA’ as one way to conceptualize and understand LED. The research amalgamates fourteen theories related to LED to present a theoretical foundation for “economic DNA theory”. The overarching question that this research tries to answer is do cities have a unique economic DNA that significantly impacts the city's direction of growth. If yes, what constitutes its economic DNA, and how robust is the DNA to change/mutation over time?
Racial-ethnic exposure disparities to airborne ultrafine particles in the United States
Saha, Provat K.; Presto, Albert A.; Hankey, Steven C.; Marshall, Julian D.; Robinson, Allen L. (IOP Publishing, 2022-10)
Ultrafine particles ('UFP'; <100 nm in diameter) are a subset of fine particulate matter (PM2.5); they have different sources and spatial patterns. Toxicological studies suggest UFP may be more toxic per mass than PM2.5. Racial-ethnic exposure disparities for PM2.5 are well documented; national exposure disparities for UFP remain unexplored due to a lack of national exposure estimates. Here, we combine high-spatial-resolution (census block level) national-scale estimates of long-term, ambient particle number concentrations (PNC; a measure of UFP) with publicly available demographic data (census block-group level) to investigate exposure disparities by race-ethnicity and income across the continental United States. PNC exposure for racial-ethnic minorities (Asian, Black, Hispanic) is 35% higher than the overall national mean. The magnitudes of exposure disparities vary spatially. Disparities are generally larger in densely populated metropolitan areas. The magnitudes of disparities are much larger for PNC than for PM2.5; PM2.5 exposure for racial-ethnic minorities is 9% higher than the overall national mean. Our analysis shows that PNC exposure disparities cannot be explained by differences in income. Whites of all incomes, including low-income Whites, have substantially lower average PNC exposures than people of color of all incomes. A higher proportion of traffic and other PNC sources are located near many minority communities. This means that the exposure disparities are structural and strongly tied to where certain subsets of the population live and that simply reducing PNC emissions nationwide will not reduce these disparities.
The COVID-19 impacts on bikeshare systems in small rural communities: Case study of bikeshare riders in Montgomery County, VA
Almannaa, Mohammed; Woodson, Cat; Ashqar, Huthaifa; Elhenawy, Mohammed (Public Library of Science, 2022-12)
The shared and micro-mobility industry (ride sharing and hailing, carpooling, bike and e-scooter shares) saw direct and almost immediate impacts from COVID-19 restrictions, orders and recommendations from local governments and authorities. However, the severity of that impact differed greatly depending on variables such as different government guidelines, operating policies, system resiliency, geography and user profiles. This study investigated the impacts of the pandemic regarding bike-share travel behavior in Montgomery County, VA. We used bike-usage dataset covering two small towns in Montgomery county, namely: Blacksburg and Christiansburg, including Virginia Tech campus. The dataset used covers the period of Jan 2019-Dec 2021 with more than 14,555 trips and 5,154 active users. Findings indicated that a bikeshare user's average trip distance and duration increased in 2020 (compared to 2019) from 2+ miles to 4+ and from half an hour to about an hour. While there was a slight drop in 2021, bikeshare users continued to travel farther distances and spend more time on the bikes than pre-COVID trips. When those averages were unpacked to compare weekday trips to weekend trips, a few interesting trip patterns were observed. Unsurprisingly, more trips still took place on the weekends (increasing from 2x as many trips to 4x as many trips than the weekday). These findings could help to better understand traveler's choices and behavior when encountering future pandemics.
Overview of Walking Rates, Walking Safety, and Government Policies to Encourage More and Safer Walking in Europe and North America
Buehler, Ralph; Pucher, John (MDPI, 2023-03-24)
Walking is the most sustainable means of daily travel for short trip distances and is a key component of the overall transport system. This paper documents variation in walking rates among countries, cities in the same country, and in different parts of the same city. Our international analysis of official government statistics shows that walking rates are highest for short trips, higher for women than for men, decline with increasing income, and remain constant as age increases. Walking fatality rates are much higher in the USA compared with the other countries we examined, both per capita and per km walked. Government policies that would increase walking rates while improving pedestrian safety include: integrated networks of safe and convenient walking infrastructure; roadways and intersections designed for the needs of pedestrians; land-use regulations that encourage mixed uses and short trip distances; lower city-wide speed limits and traffic calming in residential neighborhoods; reduced supply and increased price of parking; traffic laws that give priority to pedestrians; improved traffic education for motorists and non-motorists; tax surcharges on large personal vehicles; and strict enforcement of laws against drink and distracted driving. Five decades of success with these policies in many European cities provide practical examples for car-oriented cities to follow, especially in North America.
