    This study examines the transportation patterns and potential barriers among migrant families and workers in Adams County, Pennsylvania. The objective of this study is to determine whether barriers to transportation exist in the county, and if so, how these barriers impact the population facing them. Our study examines solutions such as more universal license policies or a potential public transportation option. To collect data and carry out our project, we distributed surveys in English and Spanish families through the Center for Public Service at Gettysburg College. We had the potential to receive responses from around 70 families, and ultimately received responses from 32 families. Our research indicates that 38% of our surveyed population do not possess driver’s licenses. Therefore, a significant portion of our surveyed population faces challenges in their right to mobility – for example, our results show challenges in accessing public goods, such as through difficulty in accessing supermarkets/ grocery stores. Most of our surveyed population report low usage of alternative modes of transportation other than private cars, specifically public transportation, whether by choice or from a lack of access. A limitation in our research design was our sample size and selection – because we found participants through an existing college program, our population is not necessarily representative of the greater Adams county migrant worker population. Further studies should investigate the inaccessibility to buses and find a more accessible range for bus stops in which all members of the community have access. Rural areas present unique challenges for travel, directly impacting migrant communities due to their challenge accessing drivers’ driver licenses and lack of modes of transportation

    About this Project In the fall of 2018, 14 of the families and 32 students from two first-year seminars, Crossing Borders: Immigration, Identity, and Development and Immigrant Stories, worked together to create this cookbook. Families submitted their favorite dishes and then invited students to their homes to demonstrate the preparation. As they cooked and ate together, students recorded the steps to make the recipe and listened as connections between food, memory, family, migration, traditions, and religion emerged. Harvesting Memory, Preserving Home: A Cookbook of the Painted Turtle Farm is the product of this undertaking. In it, we offer the collection of recipes as well as a short story from each family, bring meaning to the food we eat, the places life brings us, and the memories we share. Sobre este Projecto En el otoño de 2018, 12 de las familias y 32 estudiantes de dos clases, Cruzando Fronteras: Immigración, Identidad, y Desarrollo y Las Historias Immigrantes trabajaron juntos para cear este libro de cocina. Las familias escogieron platos con una importancia o una memoria especial para preparar en sus casas con los estudiantes. Durante el proceso de concinar y comer juntos, los estudiantes anotaron los pasos para preparar la receta. Ellos escucharon las conexiones entre la comida, la memoria, la familia, la migración, las tradiciones, y la religión. Cosechando Memoria, Preservando el Hogar: Un Libro de Cocina de la Granja de la Tortuga Pintada es el fruto de este proyecto. Ofrecemos la collección de recetas además de una historia breve de cada familia, para dar significado a los alimentos que comemos, los lugares donde la vida nos trae, y las memorias que nos compartimos

    Search for standard model production of four top quarks in the lepton + jets channel in pp collisions at √s = 8 TeV

    Open Access, Copyright CERN, for the benefit of the CMS Collaboration. Article funded by SCOAP3.Abstract: A search is presented for standard model (SM) production of four top quarks (Formula presented.) in pp collisions in the lepton + jets channel. The data correspond to an integrated luminosity of 19.6 fb−1 recorded at a centre-of-mass energy of 8 TeV with the CMS detector at the CERN LHC. The expected cross section for SM (Formula presented.) production is (Formula presented.). A combination of kinematic reconstruction and multivariate techniques is used to distinguish between the small signal and large background. The data are consistent with expectations of the SM, and an upper limit of 32 fb is set at a 95% confidence level on the cross section for producing four top quarks in the SM, where a limit of 32 ± 17 fb is expected

    Study of Z boson production in pPb collisions at √sNN=5.02 TeV

    Get PDF
    The production of Z bosons in pPb collisions at root S-NN = 5.02 TeV is studied by the CMS experiment via the electron and muon decay channels. The inclusive cross section is compared to pp collision predictions, and found to scale with the number of elementary nucleon-nucleon collisions. The differential cross sections as a function of the Z boson rapidity and transverse momentum are measured. Though they are found to be consistent within uncertainty with theoretical predictions both with and without nuclear effects, the forward-backward asymmetry suggests the presence of nuclear effects at large rapidities. These results provide new data for constraining nuclear parton distribution functions

    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.

    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

    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

    Search for stop and higgsino production using diphoton Higgs boson decays

    Get PDF
    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
