Resources for Supporting Mathematics and Data Science Instructors During COVID-19
No full textIn late May of 2020, a few months after the raging COVID-19 pandemic forced university faculty to quickly switch to online teaching, the Associated Colleges of the South (ACS) released a call for grant applications to support working groups to help faculty within our consortium who will be teaching during the pandemic (e.g., from hybrid courses with some remote/online components to fully remote/online courses; socially distanced face-to-face courses). We replied to this call and the ACS awarded the six of us (from four ACS schools) a Summer Rapid Response Grant in early June. The grant funded our efforts to create and provide to other faculty Mathematics and Data Science Resources to Support Socially Relevant Teaching in the Time of COVID-19. This paper summarizes our efforts and includes the resources that we developed
Photoproduction of the F2(1270) Meson Using the CLAS Detector
No full textThe quark structure of the f2(1270) meson has, for many years, been assumed to be a pure quark-antiquark qq ̄ resonance with quantum numbers J PC = 2++. Recently, it was proposed that the f2(1270) is a molecular state made from the attractive interaction of two ρ mesons. Such a state would be expected to decay strongly to final states with charged pions due to the dominant decay ρ -\u3e π+ π−, whereas decay to two neutral pions would likely be suppressed. Here, we measure for the first time the reaction gamma p -\u3e π+ π− p, using the CEBAF Large Acceptance Spectrometer detector at Jefferson Lab for incident beam energies between 3.6 and 5.4 GeV. Differential cross sections, dσ/dt, for f2 (1270) photoproduction are extracted with good precision due to low backgrounds and are compared to theoretical calculations
Seeing like a Starving State: The Soviet Political Economy of Death in the Blockade of Leningrad.
No full textState elites and officials ``see” their polities and societies through ideological and symbolic lenses that shape what they seek and perceive as they devise policies. But what happens to that sight and vision during moments of challenge and duress, and with what effect on policies? This article uses the example of the Blockade of Leningrad to begin an exploration of this subject. The pre-war Soviet state and Communist Party had a “double vision”, seeing Soviet society as an object for utopian plans and projects (a “high modernist” vision), and as an amorphous source of constant potential risk (e. g. counter-revolution). Extreme duress and challenges to survival from the Blockade challenged both facets of this double vision. What began to emerge was a more pragmatic vision centered on maintaining state authority and political order. We use state perception of and policies towards death and, as an extension, defending (civilian) life. Brief explorations of how state elites and officials perceived death, disposal labor (coping with corpses), and life (mothers) reveals a more realistic pragmatism, less deferrent to ideology, beginning to emerge. We conclude that this points to a possible “Blockade Bolshevism \u27\u27 as a shifting formula of rule and possibilities of a “NEP reboot” lost to high Stalinism after the war
Larval chondrocranial and internal oral morphology of the neotropical treefrog Boana crepitans (Wied-Neuwied, 1824; Amphibia, Anura, Hylidae)
Get PDFWe describe the internal oral morphology and chondrocranial anatomy for Boana crepitans tadpoles, and compare them with available descriptions for other species in the subfamily Cophomantinae. Among species of the Boana faber group, the chondrocranial anatomy has been reported only for one species internal oral morphology and cranial anatomy are similar to other described species of Boana and Cophomantinae. B. crepitans lacks unique features in the oral cavity and chondrocranium that would distinguish it from other congeneric species. We identify six characters from the internal oral anatomy of tadpoles unique for Cophomantinae. In addition, Boana has infralabial papillae projections, buccal floor arena papillae, and lateral ridge papillae projections shorter than those described for Aplastodiscus and Bokermannohyla

Individual differences in ethics positions: The EPQ-5
No full textWe revised the Ethics Position Questionnaire (EPQ), which measures variations in sensitivity to harm (idealism) and to moral standards (relativism). Study 1 identified the core components of the measured constructs theoretically and verified those features through confirmatory factor analysis (n = 2,778). Study 2 replicated these findings (n = 10,707), contrasted the theoretically defined two-factor model to alternative models, and tested for invariance of factor covariances and mean structures for men and women. Study 3 examined the relationship between the EPQ and related indicators of ethical thought (values and moral foundations) and the theory’s four-fold classification typology of exceptionists, subjectivists, absolutists, and situationists. The three studies substantially reduced the original EPQ’s length, clarified the conceptual interpretation of the idealism and relativism scales, affirmed the EPQ’s predictive and convergent validity, and supported the four-fold classification of individuals into ethics positions. Implications for previous findings and suggestions for future research are discussed
Nonprofits and Government Agencies Addressing the Needs of Mental Health Community
Get PDFNonprofit organizations have been utilizing cross-sector collaboration to address problems that are not able to be solved on their own. A partner to make said collaboration can be with any organization, business, or volunteer who has the same goals as the nonprofit organization. Mental health nonprofit organizations specifically need more partners due to how little the world knows about mental health and mental illnesses. The government is one partner many mental health organizations aim to collaborate with. Government contracts have been known to help with the many challenges nonprofit organizations face like funding and services. Previous research has suggested this collaboration has swayed nonprofit organizations from their mission due to competition and hindrances that come about in the collaboration. Nonprofit organizations need to stay on track with their mission and not worry about competition. Therefore, this collaboration could be a negative one. This study uses qualitative data from interview questions asked to employees in mental health nonprofit organizations, to analyze if there is a connection between mission fulfillment and government collaboration in the mental health nonprofit community. The findings have shown a little towards the previous research of the competition, but not enough to say if it is true or not. There are some themes showing a good relationship in the partnership as well, indicating this collaboration could be a good one for nonprofit organizations to consider. There needs to be more research done to conclude if the collaboration has been efficient. Persons in the nonprofit community can take this research into their nonprofit organizations, deciding if this collaboration could be used for their own. Policymakers could also take this research into account for future collaborations with nonprofit organizations. The findings hope to help shape what nonprofit organizations and researchers do in the future, to help with the never-ending problem of mental illness
Argument Mining on Twitter: A Case Study on the Planned Parenthood Debate
No full textTwitter is a popular platform to share opinions and claims, which may be accompanied by the underlying rationale. Such information can be invaluable to policy makers, marketers and social scientists, to name a few. However, the effort to mine arguments on Twitter has been limited, mainly because a tweet is typically too short to contain an argument — both a claim and a premise. In this paper, we propose a novel problem formulation to mine arguments from Twitter: We formulate argument mining on Twitter as a text classification task to identify tweets that serve as premises for a hashtag that represents a claim of interest. To demonstrate the efficacy of this formulation, we mine arguments for and against funding Planned Parenthood expressed in tweets. We first present a new dataset of 24,100 tweets containing hashtag #StandWithPP or #DefundPP, manually labeled as SUPPORT WITH REASON, SUPPORT WITHOUT REASON, and NO EXPLICIT SUPPORT. We then train classifiers to determine the types of tweets, achieving the best performance of 71% F1. Our results manifest claim-specific keywords as the most informative features, which in turn reveal prominent arguments for and against funding Planned Parenthood
An Agent-Based Model to Evaluate the Effect of Socioeconomic Status and Demographic Factors on COVID-19 Prevalence and Mortality
Get PDFThe purpose of the project is to discover how the prevalence and mortality of a pandemic change depending on a population’s demographic factors as well as various intervention policies through a NetLogo agent-based model. This model will simulate how demographic factors affect the course of COVID-19 (infection rate, recovery rate, and death rate). Demographic factors of interest will include population density, income distribution, age distribution, and number of hospital beds per capita. Intervention policies include vaccination, social distancing, mask wearing, mass testing, and quarantining. Conclusions about the effect of demographic factors on the infection, recovery, and death rate will be based on comparative analysis among different case studies
