    Thesis advisor: Eric DearingLongitudinal structural equation models of parent educational involvement (PEI) and student mathematics and literacy achievement were examined for 1364 students, followed from 54 months through 8th grade. Path analyses revealed evidence of bi directionality between PEI and achievement and moderation by economic risk. Specifically, two pathways of association were analyzed: parent socialization and child evocative effects. Parent socialization pathways confirmed the positive association of PEI with both math and literacy achievement -increased parent involvement was significantly associated with increased achievement across development. No evidence of child evocative pathways was found for the full sample. Additionally, economic risk was found to moderate pathways of parent socialization between PEI and achievement. Parent socialization pathways suggested involvement was most strongly and positively associated with high achievement for children with greatest levels of economic risk across childhood. These results underscore the argument that parent educational involvement should be an important goal of practice and policy aimed at closing the achievement gap between lower and higher income children. Indeed, PEI does matter more for some children than others. National policies and school procedures should be geared towards promoting PEI early among the low income parents of underperforming children, for these children not only have the most to gain from having their parents engaged in their education, but also have the most to lose.Thesis (PhD) — Boston College, 2011.Submitted to: Boston College.

    Moderator: Robin A. Robinson, University of Massachusetts Dartmouth Session Description The purpose of this interdisciplinary breakout session is to present several different approaches to the perception, creation, and implementation of community engaged research partnerships, and the range of funding sources that support them. Panelists will present brief descriptions of their projects and funding, followed by the UMass Dartmouth Research Development Manager’s insights and suggestions concerning the funding of successful matches of academic researchers and community research partners. Session Presenters, Titles and Descriptions Caitlin M. Stover, PhD, RN, PHCNS-BC, CNE, College of Nursing, Department of Community Nursing Community Based Participatory Research with Community Health Workers of the Southcoast Region My community partner and I had several ideas and projects that we wanted to work on together. To help organize our thoughts and deliverables, we applied for a spot in the first cohort of the Community Based Participatory Research Academy, a grant funded week-long course presented by the University Of Michigan School Of Public Health and the Detroit Urban Research Center. Spending a week with community engaged researchers and community leaders focused the academic-community partnership of UMass Dartmouth College of Nursing Assistant Professor Caitlin Stover and Community Leader Kathleen Murphy to promote the health of Southcoast region by mobilizing and building the capacity of Community Health Workers in the region. Monthly guided video conferences/workshops/virtual communications conducted by our assigned mentors (one community based mentor and one academic mentor) and the core of community engaged researchers assisted us in receiving a non-competitive Community Partnership Building Grant, creating and accomplishing short and long term goals, all while providing expert mentorship in applying the CBPR tenets to our work. Andrea Klimt, PhD, College of Arts and Sciences, Department of Sociology & Anthropology Pride of Place: The Potential of Collaborative Photography The Fall River Portraits project brought together university sociology and anthropology students, local high school students, and senior citizens to photographically document the complex social realities of a small economically-struggling Massachusetts city. Project photographers documented the impact of decades of economic decline on the social fabric and built environment of this urban space as well as evidence of cultural vibrancy and resilience in the city’s various neighborhoods. The resulting visual narratives fostered a pride of place and hopeful sense of self-recognition amongst local residents and encouraged the thoughtful engagement with local realities of participating college students. This project was funded by the UMass President\u27s Office, Creative Economy Award. Christina Cipriano, PhD, College of Arts and Sciences, Department of Psychology Class Interrupted: Improving Under-studied Classroom Environments Funded by the William T. Grant Foundation and recently, the University of Massachusetts Dartmouth, the RELATE Project has been conducting systematic investigations of self-contained classrooms over the past four years across the Northeast. Towards the end of improving outcomes for students and educators in self-contained special education classrooms, we are advancing the science of classroom observation and improving the quality of educational experiences, one classroom at a time. To date, our work has resulted in a new psychometrically validated tool for evaluating effective interactions in these classrooms and an ecologically valid team-based professional development approach for teacher-paraeducator teams. Robin A. Robinson, PhD, PsyD, College of Arts and Sciences, Department of Sociology & Anthropology Psychological Foundations of Power and Relational Abuse Amongst Rural and Small-Town Teens Initially funded by a pilot grant from the UMass Medical School CTSA-CER Pilot Program, and in community partnership with the Cape Cod Justice for Youth Collaborative and other member agencies of the Barnstable County Council for Children, Youth, and Families, this multi-stage project addressed the question: What are the conscious and unconscious psychological processes and power dynamics that explain behaviors associated with “teen dating violence”? The strong collaborative, and integrated, relationship that already existed between the PI and community partners contributed to the success of this pilot study, and facilitated new alliances amongst ancillary agencies. Collaborations has included regional organization of focus groups across Barnstable County (Cape Cod) to produce a data pool of first-person perspectives of teen relationships and violence in contexts of community challenges and supports. The work has considered diverse social and economic contexts as variable forces that affect psychological processes, to explore the psychology of teen relational abuse.

    Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

    Get PDF
    Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

    Severe early onset preeclampsia: short and long term clinical, psychosocial and biochemical aspects

    Get PDF
    Preeclampsia is a pregnancy specific disorder commonly defined as de novo hypertension and proteinuria after 20 weeks gestational age. It occurs in approximately 3-5% of pregnancies and it is still a major cause of both foetal and maternal morbidity and mortality worldwide1. As extensive research has not yet elucidated the aetiology of preeclampsia, there are no rational preventive or therapeutic interventions available. The only rational treatment is delivery, which benefits the mother but is not in the interest of the foetus, if remote from term. Early onset preeclampsia (<32 weeks’ gestational age) occurs in less than 1% of pregnancies. It is, however often associated with maternal morbidity as the risk of progression to severe maternal disease is inversely related with gestational age at onset2. Resulting prematurity is therefore the main cause of neonatal mortality and morbidity in patients with severe preeclampsia3. Although the discussion is ongoing, perinatal survival is suggested to be increased in patients with preterm preeclampsia by expectant, non-interventional management. This temporising treatment option to lengthen pregnancy includes the use of antihypertensive medication to control hypertension, magnesium sulphate to prevent eclampsia and corticosteroids to enhance foetal lung maturity4. With optimal maternal haemodynamic status and reassuring foetal condition this results on average in an extension of 2 weeks. Prolongation of these pregnancies is a great challenge for clinicians to balance between potential maternal risks on one the eve hand and possible foetal benefits on the other. Clinical controversies regarding prolongation of preterm preeclamptic pregnancies still exist – also taking into account that preeclampsia is the leading cause of maternal mortality in the Netherlands5 - a debate which is even more pronounced in very preterm pregnancies with questionable foetal viability6-9. Do maternal risks of prolongation of these very early pregnancies outweigh the chances of neonatal survival? Counselling of women with very early onset preeclampsia not only comprises of knowledge of the outcome of those particular pregnancies, but also knowledge of outcomes of future pregnancies of these women is of major clinical importance. This thesis opens with a review of the literature on identifiable risk factors of preeclampsia

    Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

    Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

    Get PDF
    One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI

    Search for stop and higgsino production using diphoton Higgs boson decays

    Results are presented of a search for a "natural" supersymmetry scenario with gauge mediated symmetry breaking. It is assumed that only the supersymmetric partners of the top-quark (stop) and the Higgs boson (higgsino) are accessible. Events are examined in which there are two photons forming a Higgs boson candidate, and at least two b-quark jets. In 19.7 inverse femtobarns of proton-proton collision data at sqrt(s) = 8 TeV, recorded in the CMS experiment, no evidence of a signal is found and lower limits at the 95% confidence level are set, excluding the stop mass below 360 to 410 GeV, depending on the higgsino mass

    Impacts of the Tropical Pacific/Indian Oceans on the Seasonal Cycle of the West African Monsoon

    Get PDF
    The current consensus is that drought has developed in the Sahel during the second half of the twentieth century as a result of remote effects of oceanic anomalies amplified by local land–atmosphere interactions. This paper focuses on the impacts of oceanic anomalies upon West African climate and specifically aims to identify those from SST anomalies in the Pacific/Indian Oceans during spring and summer seasons, when they were significant. Idealized sensitivity experiments are performed with four atmospheric general circulation models (AGCMs). The prescribed SST patterns used in the AGCMs are based on the leading mode of covariability between SST anomalies over the Pacific/Indian Oceans and summer rainfall over West Africa. The results show that such oceanic anomalies in the Pacific/Indian Ocean lead to a northward shift of an anomalous dry belt from the Gulf of Guinea to the Sahel as the season advances. In the Sahel, the magnitude of rainfall anomalies is comparable to that obtained by other authors using SST anomalies confined to the proximity of the Atlantic Ocean. The mechanism connecting the Pacific/Indian SST anomalies with West African rainfall has a strong seasonal cycle. In spring (May and June), anomalous subsidence develops over both the Maritime Continent and the equatorial Atlantic in response to the enhanced equatorial heating. Precipitation increases over continental West Africa in association with stronger zonal convergence of moisture. In addition, precipitation decreases over the Gulf of Guinea. During the monsoon peak (July and August), the SST anomalies move westward over the equatorial Pacific and the two regions where subsidence occurred earlier in the seasons merge over West Africa. The monsoon weakens and rainfall decreases over the Sahel, especially in August.Peer reviewe
