Designing Safety: Community Safety Initiatives Managed By The New York City Department Of Youth And Community Development, Kwan-Lamar Blount-Hill, Patricia A. Cobar, Fidel L. Osorio, Sheyla A. Delgado, Jeffrey A. Butts

Publications and Research

New York City supplements traditional policing with community-based strategies to prevent crime and violence. At the request of the Department of Youth and Community Development, the Research and Evaluation Center at John Jay College reviewed three such programs: the Crisis Management System (CMS), the Mayor’s Action Plan for Neighborhood Safety (MAP), and the Precision Employment Initiative (PEI). While grounded in promising practices, these initiatives have not yet undergone rigorous evaluation. Additional research is needed to assess their effectiveness and guide potential expansion efforts.


Students' Perceptions Of Professional Short-Messaging Education In Undergraduate Courses, Seth S. Frei, Allison M. Alford, Ashly B. Smith Nov 2023

Students' Perceptions Of Professional Short-Messaging Education In Undergraduate Courses, Seth S. Frei, Allison M. Alford, Ashly B. Smith

Journal of Communication Pedagogy

The popularity of short-messaging formats, like text and chat, is on the rise in the workplace with many employees preferring this style over long-form options like email. While many businesses expect employees to communicate using short messages, students may be ill-equipped to effectively use these methods due to a lack of formal training. This study sets out to understand students’ experience, confidence, and education related to professional short messaging. Results indicate a correlation between confidence and experience levels in writing text and chat messages. Further, the participants who indicated they had training on writing short messages, indicated they learned it …


Hydrometeorological Analysis Of A Flooding Event In Fujairah Emirate, Ahmad Abed Rabu Albreiki Nov 2023

Hydrometeorological Analysis Of A Flooding Event In Fujairah Emirate, Ahmad Abed Rabu Albreiki

Theses

This thesis conducts an extensive hydrological examination of a flooding event in Fujairah emirate, a partially dry landscape distinguished by its exceptional land utilization and soil composition. This research reveals crucial knowledge about how Fujairah Emirate basins behave hydrologically by fusing land use, land cover classification, hydrological soil groups, weighted Curve Number (CN), maximum discharge computations, and return period evaluations. One fundamental discovery is the significant differences in CN values across the region's basins. These differences highlight the powerful influence of land use and soil composition on the likelihood of water runoff. Basins with urbanization and impermeable surfaces tend to …

To assess the public health impact of the COVID-19 pandemic on mental health, investigators from the National Institutes of Health Environmental influences on Child Health Outcomes (ECHO) research program developed the Pandemic-Related Traumatic Stress Scale (PTSS). Based on the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) acute stress disorder symptom criteria, the PTSS is designed for adolescent (13–21 years) and adult self-report and caregiver-report on 3–12-year-olds. To evaluate psychometric properties, we used PTSS data collected between April 2020 and August 2021 from non-pregnant adult caregivers (n = 11,483), pregnant/postpartum individuals (n = 1,656), …

Advocacy Spotlight: Important: State Issues Changes To Delegation Of Duties Rules, Neema Katibai Jd Nov 2023

Advocacy Spotlight: Important: State Issues Changes To Delegation Of Duties Rules, Neema Katibai Jd

The Journal of the Michigan Dental Association

The Michigan Board of Dentistry has introduced changes to the rules governing the delegation of duties to dental auxiliaries, including the reclassification of "dental assistants" (those not formally trained or licensed) as "unregistered dental auxiliaries" (UDAs). The classification Registered Dental Assistant (RDA) remains. Changes involve the supervision levels for specific tasks and guiding training UDAs for orthodontic duties. Notable changes include allowing UDAs to perform certain orthodontic tasks and expanding their scope of work to include duties such as taking impressions, polishing, and providing nutritional counseling. Dental professionals should know these changes and the supervision required for delegation to UDAs …


An Empowerment Evaluation Of Colorado Mountain College’S Mountain Scholars Program Via Latino Alumni Aspirational Goals And Outcomes, Laura Anne Bruch Nov 2023

An Empowerment Evaluation Of Colorado Mountain College’S Mountain Scholars Program Via Latino Alumni Aspirational Goals And Outcomes, Laura Anne Bruch

Electronic Theses and Dissertations

This qualitative inquiry evaluated Colorado Mountain College’s (CMC) in-house Mountain Scholars Program (MSP) via semi-structured interviews with five of its Latino alumni. This study’s assets-based social justice/transformative philosophical framework included David Fetterman’s methodological empowerment evaluation and Tara Yosso’s conceptual community cultural wealth (CCW) theory. This dissertation in practice examined the gap in literature with regards to an in-house student support services program evaluation that partners with the community and focuses on Latinos’ aspirations and aspirational outcomes. I wanted to be a worthy witness to the student demographic group at CMC, as well as at most American postsecondary institutions, considered the …


Income Inequality, Social Mobility, And Electoral Participation In The U.S. Counties: Revisiting The Inequality-Participation Nexus, Dongkyu Kim, Mi-Son Kim, Sang-Jic Lee Nov 2023

Income Inequality, Social Mobility, And Electoral Participation In The U.S. Counties: Revisiting The Inequality-Participation Nexus, Dongkyu Kim, Mi-Son Kim, Sang-Jic Lee

Political Science Faculty Publications

Previous research has provided contested hypotheses about the impact of income inequality on electoral participation. This study reexamines the debate between conflict and relative power theories by focusing on a largely ignored factor: social mobility. We argue that social mobility conditions the inequality-participation nexus by alleviating the frustration, class conflict, and efficacy gaps between the rich and the poor that the prevailing theories assume income inequality to create. By utilizing the Cooperative Congressional Election Survey, we test this argument focusing on US counties. Our analysis confirms that the effects of income inequality on citizens’ likelihood of voting vary depending on …


“Mere Guesswork”: Clarifying The Role Of Intelligence, Mentality, And Psychometric Testing In The Diagnosis Of “Mental Defectives” For Sterilization In Alberta From 1929 To 1972., Elliott M. Reichardt, Henderikus J. Stam, Kim Tan-Macneill Nov 2023

“Mere Guesswork”: Clarifying The Role Of Intelligence, Mentality, And Psychometric Testing In The Diagnosis Of “Mental Defectives” For Sterilization In Alberta From 1929 To 1972., Elliott M. Reichardt, Henderikus J. Stam, Kim Tan-Macneill

Sociology & Anthropology Faculty publications

From 1929 until 1972, the Alberta Eugenics Board (the Board) recommended that 4,739 individuals be sterilized. The original 1928 act that legalized eugenic sterilization stipulated that the surgery itself required the consent of the individual or their caregiver; however, in 1937, the Alberta government removed the consent requirement for such cases where the Board determined individual patients to be “mental defectives.” By analyzing published reports, case histories, medical journals, and primary sources from the Board, we situate the concept of “mental defective” in a historical context to clarify the Board’s diagnostic process. By analyzing how the Board found individuals to …

Behavioral Science Interventions Could Increase Snap Comprehension And Awareness Among Military Families, Colleen Heflin, Hannah Patnaik, Leonard M. Lopoo, Siobhan O'Keefe

Center for Policy Research

Food insecurity is more common among military families than the general population, and the transition from active service to civilian life is a time of heightened risk. The Supplemental Nutritional Assistance Program (SNAP) is designed to support food security among low-income families. Many eligible military and veteran families do not enroll in SNAP due to a lack of information, stigma, and administrative barriers. This brief highlights findings from a survey experiment conducted in 2022 and 2023 to assess how small changes to SNAP informational flyers, such as simplifying information provided about SNAP, highlighting that other veterans use SNAP, and emphasizing …

Unmaking Egalitarianism: Comparing Sources Of Political Change In An Amazonian Society, Christopher Von Rueden Nov 2023

Unmaking Egalitarianism: Comparing Sources Of Political Change In An Amazonian Society, Christopher Von Rueden

Jepson School of Leadership Studies articles, book chapters and other publications

Politically egalitarian societies were likely more common in pre-history than in recent millenia. Why did societies become more hierarchical? Answers to this question remain debated, based on evidence largely drawn from archaeological case studies or comparison of societies from the ethnographic record. I suggest that modern small-scale societies transitioning to market economies can provide complementary tests of the sources of political inequality. I first describe moderate variation in men's influence during community meetings (i.e. political inequality) across four relatively egalitarian Tsimane villages in the Bolivian Amazon, as well as within one of these villages over twelve years. I then assess …


Google Sge: A New Way To Search, Teach, And Resist, Tessa Withorn Nov 2023

Google Sge: A New Way To Search, Teach, And Resist, Tessa Withorn

Faculty and Staff Scholarship

In May 2023, amidst the fanfare and outcries over ChatGPT, Google quietly rolled out early access to new features in Search Labs, a user-based experimental testing ground for Search Generative Experience (SGE). Google pitches SGE as a new way of searching that uses generative artificial intelligence (AI) to “understand a topic faster, uncover new viewpoints and insights, and get things done more easily,” but later adds that it also helps make “complex purchase decisions faster and much easier.”2 Interested users can simply tap the Labs icon in Google Chrome or a Google search on an Android device to sign up. …

What Do Americans Think About Federal Tax Options To Support Transportation? Results From Year Fourteen Of A National Survey, Asha Weinstein Agrawal, Hilary Nixon, Adam Azevedo Nov 2023

What Do Americans Think About Federal Tax Options To Support Transportation? Results From Year Fourteen Of A National Survey, Asha Weinstein Agrawal, Hilary Nixon, Adam Azevedo

Mineta Transportation Institute

This report summarizes the results from the fourteenth year of a national public opinion survey asking U.S. adults questions related to their views on federal transportation taxes. A nationally representative sample of 2,531 respondents completed the online survey from February 13 to March 23, 2023. The questions test public opinions about raising the federal gas tax rate, replacing the federal gas tax with a new mileage fee, and imposing a mileage fee just on commercial travel. In addition to asking directly about support for these tax options, the survey collected data on respondents’ views on the quality of their local …


Financial Crisis And Female Entrepreneurship: Evidence From South Korea, Jungho Lee, Sunha Myong Nov 2023

Financial Crisis And Female Entrepreneurship: Evidence From South Korea, Jungho Lee, Sunha Myong

Research Collection School Of Economics

We document a drastic increase in female-owned manufacturing firms in South Korea after the 1997 financial crisis. During the crisis, a major banking sector reform was conducted, and many underperforming bank branches were forced to close down. Using a geographical variation of bank branch closures during the reform, we show that the banking sector reform resulted in a rise in female entrepreneurship. We present evidence that male-owned firms were preferred by the closeddown bank branches, despite female-owned firms exhibiting lower risks and higher returns. The banking sector reform, although not explicitly aimed at addressing gender disparities, substantially benefited female entrepreneurs …


Decomposability And Strategy-Proofness In Multidimensional Models, Shurojit Chatterji, Huaxia Zeng Nov 2023

Decomposability And Strategy-Proofness In Multidimensional Models, Shurojit Chatterji, Huaxia Zeng

Research Collection School Of Economics

We introduce the notion of a multidimensional hybrid preference domain on a (finite) set of alternatives that is a Cartesian product of finitely many components. We demonstrate that in a model of public goods provision, multidimensional hybrid preferences arise naturally through assembling marginal preferences under the condition of semi-separability - a weakening of separability. The main result shows that under a suitable “richness” condition, every strategy-proof rule on this domain can be decomposed into component-wise strategy-proof rules, and more importantly every domain of preferences that reconciles decomposability of rules with strategy-proofness must be a multidimensional hybrid domain.


Legal Protection Of Property Rights: A Dynamic Evolution Model, Fali Huang Nov 2023

Legal Protection Of Property Rights: A Dynamic Evolution Model, Fali Huang

Research Collection School Of Economics

This paper presents an analysis of a dynamic evolution model of institutions, focusing on the factors affecting the security of property rights such as coercive capacity, political power, legal quality, and private protection. These factors are endogenously determined in equilibrium, allowing legal quality to serve as a summary indicator of property security. The primary finding of the study indicates that the legal protection of property rights tends to increase over time, driven by a decline in the economy's vulnerability to expropriation, particularly due to the growing importance of commercial and industrial activities relative to agriculture. Furthermore, the coexistence of the …


How Tiktok “Locks In” Its Users With Reference To What Happened In The Homeland Version Douyin Application, Yang Yang, Li Zi'ang, Zhigen Zhao, Sabrina (Zi Tong) Peng, Liyu Dou, Changyu Li, Yinqi Wang Nov 2023

How Tiktok “Locks In” Its Users With Reference To What Happened In The Homeland Version Douyin Application, Yang Yang, Li Zi'ang, Zhigen Zhao, Sabrina (Zi Tong) Peng, Liyu Dou, Changyu Li, Yinqi Wang

Research Collection School Of Economics

In October 2022, Douyin, the homeland version of TikTok, introduced a new rule requiring all its users to promote only Douyin-approved products during their live-streaming events and in their non-live short-videos. This requirement essentially restricts its users to monetize their content strictly through Douyin-approved products, as promoting products has become the most important source of income for Douyin users. This requirement essentially creates a lock-in effect.


Navigating Risk In Vendor Data Privacy Practices: An Analysis Of Elsevier's Sciencedirect, Becky Yoose, Nick Shockey Nov 2023

Navigating Risk In Vendor Data Privacy Practices: An Analysis Of Elsevier's Sciencedirect, Becky Yoose, Nick Shockey

Copyright, Fair Use, Scholarly Communication, etc.

Executive Summary

As libraries transitioned from buying materials to licensing content, serious threats to privacy followed. This change shifted more control over library user data (and whether it is collected or kept at all) from the local library to third-party vendors, including personal data about what people search for and what they read. This transition has further reinforced the move by some of the largest academic publishers to move beyond content and become data analytics businesses that provide platforms of tools used throughout the research lifecycle that can collect user data at each stage. These companies have an increasing incentive …

After Great Pain: The Uses Of Religious Folklore In Kenji Mizoguchi’S Sansho The Bailiff (Jp 1954) And Kaneto Shindo’S Onibaba (Jp 1964), Teng-Kuan Ng Nov 2023

After Great Pain: The Uses Of Religious Folklore In Kenji Mizoguchi’S Sansho The Bailiff (Jp 1954) And Kaneto Shindo’S Onibaba (Jp 1964), Teng-Kuan Ng

Research Collection College of Integrative Studies

This article studies the adaptations and applications of religious folklore in two mas-terworks of Japanese cinema: Kenji Mizoguchi’s Sansho Dayu (Sansho the Bailiff, JP 1954) and Kaneto Shindo’s Onibaba (JP 1964). While academic approaches will often draw a strict line between narrative genres and discursive forms, these films, I argue, draw creatively from Japanese tradition for both critical and constructive purposes in the postwar context. Besides mounting trenchant criticisms of Japan’s erstwhile militaristic violence and imperial ambitions, both filmmakers present their respective female protagonists as models for spiritual and sociocultural transformation in the face of anomie. Embodying humanistic compassion on …

Information Loss In Volatility Measurement With Flat Price Trading, Peter C. B. Phillips, Jun Yu Nov 2023

Information Loss In Volatility Measurement With Flat Price Trading, Peter C. B. Phillips, Jun Yu

Research Collection School Of Economics

A model of financial asset price determination is proposed that incorporates flat trading features into an efficient price process. The model involves the superposition of a Brownian semimartingale process for the effcient price and a Bernoulli process that determines the extent of price trading. The approach is related to sticky price modeling and the Calvo pricing mechanism in macroeconomic dynamics. A limit theory for the conventional realized volatility (RV) measure of integrated volatility is developed. The results show that RV is still consistent but has an inflated asymptotic variance that depends on the probability of flat trading. Estimated quarticity is …

A Critical Examination Of The Effectiveness Of Gratitude Intervention On Well-Being Outcomes: A Within-Person Experimental Daily Diary Approach, Andree Hartanto, Manmeet Kaur, K. T. A Sandeeshwara Kasturiratna, Frosch Y. X. Quek

Research Collection School of Social Sciences

Given the rise in the global prevalence of stress and depressive symptoms, there is an increasing need to identify promising interventions that promote well-being. One potential intervention that has been widely discussed in the literature on improving well-being is the practice of gratitude. However, findings on its effectiveness have been marred by inconsistency and publication bias. Building upon past studies, the current study aims to revisit the effect of a gratitude contemplation intervention on multiple well-being outcomes by using a within-person experimental design with a daily diary approach. Multilevel modeling showed that the gratitude contemplation intervention had a significant within-person …


Problematic Smartphone Usage, Objective Smartphone Engagement, And Executive Functions: A Latent Variable Analysis, Andree Hartanto, Yi Jing Chua, Frosch Yi Xuan Quek, Joax Wong, Wei Ming Ooi Nov 2023

Problematic Smartphone Usage, Objective Smartphone Engagement, And Executive Functions: A Latent Variable Analysis, Andree Hartanto, Yi Jing Chua, Frosch Yi Xuan Quek, Joax Wong, Wei Ming Ooi

Research Collection School of Social Sciences

The negative consequences of smartphone usage have seen frequent discourse in popular media. While existing studies seek to resolve these debates in relation to executive functions, findings are still limited and mixed. This is partly due to the lack of conceptual clarity about smartphone usage, the use of self-reported measures, and problems related to task impurity. Addressing these limitations, the current study utilizes a latent variable approach to examine various types of smartphone usage, including objectively measured data-logged screen time and screen-checking, and nine executive function tasks in 260 young adults through a multi-session study. Our structural equation models showed …
