Associations Between College Students\u27 Social Media Use and Psychological Adjustment During COVID-19
Get PDFThe purpose of this study is to examine whether higher levels of social media use are associated with higher levels of psychological distress, including symptoms of depression and anxiety, and perceived stress. We hypothesize that social media use will be positively correlated with psychological difficulties. The sample includes 522 undergraduates from two liberal arts institutions from the Southeast US. Participants were administered an online survey in the fall of 2020. A second wave of data will be collected during the last week of February 2021. Measures include the Generalized Anxiety Disorder-7, Perceived Stress Scale, Adapted Social Media Use Integration Scale, and The Center for Epidemiologic Depression Scale. Once Wave 2 data are collected, we will run a series of regressions to investigate the link between social media use and psychological adjustment across two waves. These findings could be vital in understanding college students’ well-being amidst their use of and exposure to social media
Análisis de los Impactos Socio-Ambientales de dos Rutas de la Carretera Propuesta entre Pucallpa, Perú y Cruzeiro do Sul, Brasil.
No full textA medida que los gobiernos de Brasil y Perú continúan proponiendo y promoviendo la construcción de carreteras a través de la Amazonía, se vuelve cada vez más importante considerar los efectos que esta infraestructura podría tener en las diversas culturas y ecosistemas de la Amazonía. Una de las propuestas en discusión es una vía de 280+ km que conectaría las ciudades de Pucallpa, Perú y Cruzeiro do Sul, Brasil. Si bien la carretera se promociona como económicamente beneficiosa, la ruta pasará cerca, si no cruzará, territorios indígenas y áreas de conservación protegidas, en particular el Parque Nacional Serra do Divisor. La región de la Sierra del Divisor es un hotspot de biodiversidad que contiene especies raras y amenazadas cuyos hábitats son particularmente vulnerables a la invasión de carreteras. Los nuevos corredores viales también pueden facilitar la tala ilegal, el tráfico de drogas, la especulación de tierras, la inmigración y la propagación de enfermedades, poniendo en peligro la biodiversidad de la selva amazónica y potencialmente infringiendo la seguridad y la autonomía de los pueblos indígenas y rurales. Esta investigación tiene como objetivo evaluar los impactos potenciales que presenta el proyecto de la carretera Pucallpa-Cruzeiro do Sul en el medio ambiente, las sociedades y las economías del suroeste de la Amazonía utilizando una metodología mixta que incluye análisis geoespacial, teledetección y una revisión de la literatura de estudios previos sobre el impacto. de carreteras en bosques tropicales. Estos análisis intentarán expresar la escala de las repercusiones que la construcción de carreteras puede traer a las tierras fronterizas del Amazonas, ricas en bioculturalidad
Pressure on the Trigger Will Now Fire the Weapon: An Examination of how the Supreme Court, Congress, and Presidents Have Left the Legal Foundation for Executive Detention Akin to the World War II Era Internment of Japanese Americans Largely Intact
Get PDFContrary to Chief Justice Robert\u27s dicta, Trump v. Hawaii (2018) did not overrule Korematsu v. United States (1944) which upheld the exclusion of Japanese Americans from the West Coast during World War II. Korematsu and its related cases are still troublingly vital. Their expansive reading of the war powers justifying executive detention has been bolstered by the Court\u27s cases addressing detainees held at Guantanamo Bay. Hamdi v. Rumsfeld (2004), which sanctioned the detention of a U.S. citizen pursuant to the Authorization for the Use of Military Force, exposed a fundamental weakness in the Non-Detention Act, the principal statutory barrier to executive detention. Today, despite the appalling history of the World War II era internment of Japanese Americans, the authority of the President to employ preventive executive detention remains both remarkably intact and remarkably broad. That authority should be restrained by appropriate amendments to the Non-Detention Act
Business Actor Engagement: Exploring Its Antecedents and Types.
No full textBuilding on recent engagement research, this study contributes to a deepened understanding of business actor engagement (BAE) dimensions that includes both behaviors and emotions. Following a systematic combining approach, this study contextualizes and clarifies BAE. Through an analysis of dyadic data (providing firm and customers), we offer in-depth knowledge of the antecedents and types of BAE. This study identifies engagement disposition combined with engagement connectedness as the antecedents of an engagement initiative\u27s overall BAE. Building on these dynamics, we propose a conceptual BAE framework with a set of testable propositions that links BAE with its proposed antecedents. Finally, we use the empirical and theoretical insights to derive a BAE taxonomy consisting of four types that offers guidance on how to manage customers with different engagement characteristics in practice
Prospering within Mathematics.
No full textIntroduction: The “Human Interest” of Mathematics In January 1919, the President of the Carnegie Institution, the mathematician R. S. Woodward, wrote to Leonard Dickson regarding the introduction to what would become Dickson’s celebrated History of the Theory of Numbers. In particular, Woodward encouraged Dickson to “add the human interest which many of our friends who are professed humanists deny to our favorite science.” From Woodward’s perspective, this approach would give the book “the kind of sendoff its rich mine of contents so admirably deserves.”1
Just think of it. Over a century ago, as members of the American mathematics community aimed to produce work and publications that would lend credibility to the discipline, Woodward encouraged a focus on the human aspect of mathematics as a prelude to Dickson’s 1600-page study of number theory. Even more, Woodward viewed that approach as an admirable sendoff for the 400-year study. Woodward was ahead of his time. The young community aimed to create institutions to award doctoral degrees, build societies to bring colleagues together to discuss ideas, and establish publication venues to disperse research more broadly. In this broader context, however, Woodward urged Dickson, a leader in every aspect of this work at the time, to remember and celebrate the human being actually doing the work
Are Malaria Transmission-Blocking Vaccines Acceptable to High Burden Communities? Results from a Mixed Methods Study in Bo, Sierra Leone.
No full textBackground
Malaria transmission-blocking vaccines (TBVs) could help break the cycle of malaria transmission by conferring community rather than individual protection. When introducing new intervention strategies, uptake is dependent on acceptability, not just efficacy. In this exploratory study on acceptability of TBVs in Sierra Leone, it was hypothesized that TBVs would be largely acceptable to adults and health workers in areas with relatively few ongoing malaria interventions, and that (i) knowledge of malaria and vaccines, (ii) health behaviours associated with malaria and vaccines, and (iii) attitudes towards different vaccines types could lead to greater TBV acceptability. Methods
This study used a mixed methods approach in Bo, Sierra Leone, to understand community knowledge, attitudes, and practices related to malaria and vaccination in general. This included: (i) a population-based cross-sectional survey (n=615 adults), (ii) 6 focus group discussions with parents, and (iii) 20 key informant interviews. The concept of a TBV was explained to participants before they were asked about their willingness to accept this vaccine modality as part of an integrated malaria elimination programme. Results
This study found that most adults would be willing to receive a TBV vaccine. Respondents noted mostly positive past experiences with adult and childhood vaccinations for other infectious diseases and high levels of engagement in other malaria prevention behaviors such as bed nets. Perceived barriers to TBV acceptance were largely focused on general community-level distribution of a vaccine, including personal fears of vaccination and possible costs. After an explanation of the TBV mechanism, nearly all focus group and interview participants believed that community members would accept the vaccine as part of an integrated malaria control approach. Both parents and health workers offered insight on how to successfully roll-out a future TBV vaccination programme. Conclusions
The willingness of community members in Bo, Sierra Leone to accept a TBV as part of an integrated anti-malarial strategy suggests that the atypical mechanism of TBV action might not be an obstacle to future clinical trials. This study’s findings suggests that perceived general barriers to vaccination implementation, such as perceived personal fears and vaccine cost, must be addressed in future clinical and implementation research studies
