Using Pupil Transportation Data To Explore Educational Inequities And Outcomes: A Case Study From New York City, Sarah Cordes, Samantha Trajkovski, Christopher Rick, Meryle Weinstein, Amy Ellen Schwartz

Center for Policy Research

This article explores how researchers can use pupil transportation data to explore key questions about the role of transportation in educational access and equity, such as how students get to school and the effect of transportation on student outcomes. We first describe different sources of transportation data that are available to researchers, provide a brief review of relevant literature, and discuss potential sources of measurement error in pupil transportation data. Next, we use administrative data from New York City to illustrate how pupil transportation data can be used to understand transportation eligibility and assignment as well as to describe the …

Towering Intellects? Sizing Up The Relationship Between Height And Academic Success, Stephanie Coffey, Amy Ellen Schwartz

Center for Policy Research

Do tall students do better in school? While a robust literature documents higher earnings among taller people, we know little about the potential academic origins of the height earnings gradient. In this paper, we use unique student-level longitudinal data from New York City (NYC) to examine the link between height and academic outcomes, shedding light on underlying mechanisms. The centerpiece of our empirical work is a regression linking academic outcomes to height, measured as a z-score normalized to same grade/sex peers within schools. We estimate a meaningful height gradient for both boys and girls in ELA and math achievement in …

Psychometric Properties Of The Berger Hiv Stigma Scale: A Systematic Review, Stanley W. Wanjala, Ezra Too, Stanley Luchters, Amina Abubakar

Institute for Human Development, East Africa

Addressing HIV-related stigma requires the use of psychometrically sound measures. However, despite the Berger HIV stigma scale (HSS) being among the most widely used measures for assessing HIV-related stigma, no study has systematically summarised its psychometric properties. This review investigated the psychometric properties of the HSS. A systematic review of articles published between 2001 and August 2021 was undertaken (CRD42020220305) following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Additionally, we searched the grey literature and screened the reference lists of the included studies. Of the total 1241 studies that were screened, 166 were included in the …

The Effect Of Saline Flush After Rocuronium Bolus On Intubating Conditions In Adult Patients Undergoing Elective Surgery: A Randomized Controlled Trial, Ian Odari, Vitalis Mung’Ayi, Rajpreet Bal, David Odaba

Anaesthesiology, East Africa

Background: In emergency surgeries requiring endotracheal intubation, the time to effect of neuromuscular blocking drugs is a crucial time to avoid hypoxia and aspiration into the lungs. Various strategies have been undertaken to shorten this time. All these methods have positive results but some are associated with side effects. The effectiveness of a muscle relaxant can either be assessed using the train of four or intubating conditions on the Goldberg scale. In this study, we investigated the effects of a 20 ml saline bolus following intravenous rocuronium at 0.6 mg/kg on the proportions of patients with excellent intubating conditions …

The individually-tailored writing class was taught as a critical component of a comprehensive educational program that targets underrepresented racial and ethnic …

Signature Pedagogy For Entrepreneurship Education: An Emerging Perspective, Ashley Gess, Eleonora Brivio, Gianluca De Leo

International Journal for Business Education

Entrepreneurial ways of thinking and doing intersect with the knowledge and skills that a global citizen needs to thrive. There is a robust body of scholarship that identifies core entrepreneurial skills however there is a dearth of evidence addressing how to successfully teach entrepreneurship. Using the lens of experiential learning, this qualitative study examines the surface, deep, and implicit structures of professional entrepreneurial culture toward revealing a meaningful, authentic pedagogical approach for entrepreneurship education. In order to achieve this outcome, researchers utilized a semi-structured comparable multiple-case study design to engage 19 incubated entrepreneurs in focus group interviews. A replication strategy …

Are Psychological Barriers An Unseen Threat To Women In Leadership? An Interpretative Phenomenological Analysis On The Underrepresentation Of Women Chief Executive Officers In Healthcare, Nikia M. Dennis

Education Doctoral

The purpose of this qualitative study, using an interpretative phenomenological analysis methodology, was to identify if six women CEOs in New York State, who worked in the for-profit, not-for-profit, ambulatory and hospital, and nursing home healthcare subsectors of the healthcare industry encountered psychological barriers, such as low self-efficacy, low self-confidence, and low self-esteem, in their ascension to the CEO role, and if so, what strategies did they use to overcome those barriers. The semistructured interviews of the CEOs were analyzed and the findings revealed four concepts reflected in Bandura’s four sources of influence: performance, vicarious learning, verbal persuasion, and psychological …

Education Doctoral

The purpose of this phenomenological study was to examine the extent that the COVID-19 pandemic had on first-year college enrollments for the fall 2020 semester and the alternate plans that were made by Northeastern United States students. The general research question was, “What motivating factors contributed to recent high-school students’ decisions to take a gap year during the COVID-19 global pandemic?” To build an answer, this study was conducted to identify and explore the perceptions of 10 young adults who were accepted and committed to a 4-year college or university after high-school graduation, but they did not accomplish enrollment for …

Characterization Of Anti-Ana O 3 Monoclonal Antibodies And Their Application In Comparing Brazilian Cashew Cultivars, Christopher P. Mattison, Barry Vant-Hull, Ana Cecilia Ribeiro De Castro, Heidi J. Chial, Yvette Bren-Mattison, Peter J. Bechtel, Edy Sousa De Brito

School of Medicine Faculty Publications

Ana o 3 is an immuno-dominant cashew nut allergen. Four monoclonal antibodies to Ana o 3 (2H5, 6B9C1, 19C9A2, and 5B7F8) were characterized by ELISA and in silico modeling. The 2H5 antibody was the only antibody specific for cashew nut extract. In addition to cashew nut extract, the 6B9C1 and 19C9A2 antibodies recognized pistachio extract, and the 5B7F8 recognized pecan extract. All four antibodies recognized both recombinant Ana o 3.0101 and native Ana o 3. ELISA assays following treatment of purified Ana o 3 with a reducing agent indicated that the 6B9C1 and 19C9A2 antibodies likely recognize conformational epitopes, while …

Cdk5 Drives Formation Of Heterogeneous Pancreatic Neuroendocrine Tumors, Angela M. Carter, Nilesh Kumar, Brendon Herring, Chunfeng Tan, Rachael Guenter, Rahul Telange, Wayne Howse, Fabrice Viol, Tyler R. Mccaw, Hayden H. Bickerton, Priyanka Gupta, Frank Gillardon, Eugene A. Woltering, Deepti Dhall, John Totenhagen, Ronadip R. Banerjee, Elizabeth M. Kurian, Sushanth Reddy, Herbert Chen, Joerg Schrader

School of Medicine Faculty Publications

Pancreatic neuroendocrine tumors (PanNETs) are a heterogeneous population of neoplasms that arise from hormone-secreting islet cells of the pancreas and have increased markedly in incidence over the past four decades. Non-functional PanNETs, which occur more frequently than hormone-secreting tumors, are often not diagnosed until later stages of tumor development and have poorer prognoses. Development of successful therapeutics for PanNETs has been slow, partially due to a lack of diverse animal models for pre-clinical testing. Here, we report development of an inducible, conditional mouse model of PanNETs by using a bi-transgenic system for regulated expression of the aberrant activator of Cdk5, …

Stimulating Intrapreneurial Intentions With Digital Business Training In The Vet Sector: The Potential Of Massive Open Online Courses, Christian Friedl

International Journal for Business Education

It has become imperative to stimulate and support employees to behave entrepreneurially within organizations (intrapreneurship). However, little is known about how digital, massive, and scalable business education and training formats such as massive open online course (MOOCs) can contribute to vocational and educational training (VET) in general, and to nurture intrapreneurial behavior and corresponding intentions in specific. Therefore, the purpose of this paper is to explore the potential effect of a MOOC on intrapreneurial intentions of learners.
Data were acquired from 412 employees taking a MOOC on intrapreneurship for constructs embedded in the theory of planned behavior, tailored to the …

Cultivating Financial Literacy Through Secondary School Economics Education: Access To Powerful Knowledge, Emanuel Mizzi

International Journal for Business Education

‘Powerful knowledge’ is disciplinary knowledge that when learned, empowers students to make decisions in a way that will influence their lives in a positive way (Young, 2008). In this paper, the researcher employs this construct to explore the financial literacy education arising from studying secondary school economics. It emerges from the author’s research aimed at exploring teaching and learning in secondary school Maltese economics classrooms. The underlying conceptual framework for this study is critical realism. The study design consisted of interviewing and observing 14 economics teachers, together with four focus groups interviews with students. Data were analyzed by employing thematic …

School of Medicine Faculty Publications

Gun violence drastically increased in urban cities following the ease of shutdown restric-tions associated with the Coronavirus Pandemic. The association of gun violence and COVID-19 has highlighted the importance of taking a public health perspective, particularly as it relates to impacts on the Black community. In this article we discuss macro-level factors and community traumas in the city of New Orleans, an area that has had longstanding issues related to gun violence. Community structural issues, traumatic stress from disasters, and recommendations to address disparities in social determinants of health are discussed.

Assessing Vertebral Body Rotation For Percutaneous Pedicle Screw Placement In Scoliosis Surgery, Patrik Suwak, Abhishek Kumar, Kirby Bonvillain, Matthew Darlow, Peter D'Amore, Claudia Leonardi, Leland C. Mccluskey

School of Medicine Faculty Publications

Study Design: Retrospective Review. Objective: The aim of this study was to evaluate the incidence and magnitude of pedicle asymmetry as well as spinous process deviation in the healthy lumbar spine. Summary of Background Data: Minimally invasive spine surgery relies on fluoroscopic imaging as bony landmarks used for instrumentation are not exposed. The precision of techniques used to determine vertebral body rotation intraoperatively may be confounded by anatomic variation or pathology. Here, we investigate the physiologic variation in different anatomic structures of the lumbar spine used for percutaneous pedicle screw placement. Methods: 100 normal lumbar CT scans, without evidence of …

Herbivores Alleviate The Negative Effects Of Extreme Drought On Plant Community By Enhancing Dominant Species, Chong Xu, Yuguang Ke, Honghui Wu, Melinda D. Smith, Nathan P. Lemoine, Weiguo Zhang, Qiang Yu

Biological Sciences Faculty Research and Publications

Aims

Both extreme drought and insect herbivores can suppress plant growth in grassland communities. However, most studies have examined extreme drought and insects in isolation, and there is reason to believe that insects might alter the ability of grasslands to withstand drought. Unfortunately, few studies have tested the interactive effects of extreme drought and insect herbivores in grassland communities.

Methods

Here, we tested the drought–herbivore interactions using a manipulative experiment that factorially crossed extreme drought with the exclusion of insect herbivores in a temperate semiarid grassland in Inner Mongolia.

Important Findings

Our results demonstrated that both extreme drought and insect …

Kudzu Invasion And Control In Southern Upland Forests Of Mississippi, Gina M. Profetto

LSU New Orleans Theses and Dissertations

Kudzu, Pueraria montana var. lobata (Willd.), is a common invasive species throughout the American South. In southern upland mixed oak-pine forests of Mississippi, kudzu invasion generally and indiscriminately suppressed the pre-invasion plant community. Three different control methods reduced kudzu density but differed in the level of reduction achieved and in their effects on the pre-existing plant community. A combination of burning and herbicides produced the most desirable outcome in terms of restoring the pre-invasion community. Kudzu invasion significantly increased nitrate pools compared to control sites, but had no effect on ammonium or nitrite, or on the microbial processes of mineralization …

Fine Grained Delta Front Sediment Transport, Sarah Noel

LSU New Orleans Theses and Dissertations

Insights into transformative coastal processes are unlocked though understanding sediment transport mechanisms in fine-grained delta front environments. Movement of fine-grained sediments on delta fronts is not wholly explained through advection settling models. While advection settling models generally assume deposition into a still body, numerical modeling of sediment re-entrainment suggests there may be tidal, wave, and/or non-steady hydrograph influences allowing particles to reach greater distances by altering the decelerating velocity field. This research explores both an advection settling model and a mass conservation Rouse profile model to understand the irreducible delta front processes controlling sediment deposition. Using field data collected on …

Alterations In Excitatory And Inhibitory Synaptic Development Within The Mesolimbic Dopamine Pathway In A Mouse Model Of Prenatal Drug Exposure, Taylor Boggess, James C. Williamson, Ethan B. Niebergall, Hannah Sexton, Richard D. Egleton, Larry Grover, Chris Risher

Biomedical Sciences

The rise in rates of opioid abuse in recent years in the United States has led to a dramatic increase in the incidence of neonatal abstinence syndrome (NAS). Despite improved understanding of NAS and its acute symptoms, there remains a paucity of information regarding the long-term effects of prenatal exposure to drugs of abuse on neurological development. The primary goal of this study was to investigate the effects of prenatal drug exposure on synaptic connectivity within brain regions associated with the mesolimbic dopamine pathway, the primary reward pathway associated with drug abuse and addiction, in a mouse model. Our secondary …

Conserved And Divergent Features Of Neuronal Camkii Holoenzyme Structure, Function, And Highorder Assembly, Olivia R. Buonarati, Adam P. Miller, Steven J. Coultrap, K. Ulrich Bayer, Steve L. Reichow

Chemistry Faculty Publications and Presentations

Neuronal CaMKII holoenzymes (^a and ^b isoforms) enable molecular signal computation underlying learning and memory but also mediate excitotoxic neuronal death. Here, we provide a comparative analysis of these signaling devices, using single-particle electron microscopy (EM) in combination with biochemical and live cell imaging studies. In the basal state, both isoforms assemble mainly as 12-mers (but also 14-mers and even 16-mers for the b isoform). CaMKIIa and ^b isoforms adopt an ensemble of extended activatable states (with average radius of 12.6 versus 16.8 nm, respectively), characterized by multiple transient intra- and interholoenzyme interactions associated with distinct functional properties. The …
