    In 2002, The Robert Wood Johnson Foundation launched Children's Futures (CF), a 10-year community change initiative designed to improve the health and well-being of children from birth to age three throughout Trenton, NJ. CF's strategies included efforts to increase residents' access to prenatal and other health services, provide parenting skills education, improve the quality of available childcare and promote preventive healthcare among medical practices. The Foundation engaged P/PV to evaluate the implementation and outcomes of the initiative and to provide ongoing feedback on its progress.This report, and its forthcoming companion, Early Outcomes in a Community Change Effort to Improve Children's Futures, examine the promise of CF strategies. Collaboration and Community Change in the Children's Futures Initiative focuses on program implementation, participant recruitment and collaborations among Trenton's agencies. The second report examines programmatic improvements and early outcomes for CF families. Major findings from both are compiled in Children's Futures' First Five Years

    An investigation of the effects of image angle on resolution of fine detail screen printing

    Screen printing, unlike other printing processes, requires ink to be pushed through the image carrier to the substrate. When the mesh threads and their intersections cross the image area, they act as obstructions to the ink flow. In large image areas, the effect of mesh interference is minimal. In fine detail screen printing, mesh interference is a primary cause of poor or inaccurate resolution. The trend in screen printing has been toward more and finer fine line, halftone and four-color process printing. Researching methods to minimize mesh interference will enable screen printers to gain greater control over the printing process and better utilize technologies currently available for fine detail reproduction. Previous experiments had shown that the angle of a fine line image relative to the mesh threads will have an effect on resolution quality. This thesis developed a theoretical model for hypothesizing that image angle may also affect resolution in halftone screen printing. A fine line test image was developed to attempt to reproduce the results of experiments indicating a critical angle exists for fine lines, and to determine if the direction of the squeegee motion is also a factor. Halftone gray scales screened at all of the common four-color and black and white reproduction angles, as well as at the aforementioned hypothesized fine line critical angle, were used to determine if image angle has an effect on reproduceable tonal range and on the accuracy of resolution in halftone screen printing. Exposure and squeegee conditions were optimized, and the test images were printed. Data on fine line and halftone resolution was collected and statistically analyzed to determine if image angle had an effect on the resolution. In all cases, angle was found to have an effect on image resolution. However, no one angle or small range of angles was found to provide significantly better resolution than another. In the fine line test, it appeared that a relationship does exist between image resolution and the direction of squeegee motion. This was not evident in the halftone resolution data. The halftone data, however, does indicate a relationship exists between loss of percent dot area and tonal range. Further investigation of these factors in screen printing is recommended

    Water Conflict Revisited: Fresh Water Scarcity as a Key Predictor of Contemporary Armed Conflict

    For over 30 years, scholars have investigated the direct relationship between fresh water scarcity and armed conflict using a wide variety of analytical techniques. However, this body of literature has yet to provide a comprehensive empirical analysis that supports such a relationship for both interstate and intrastate conflicts. The ensuing report fills in the gaps of the existing discourse by closely reassessing the variables under consideration and employing a cross-sectional, time-series analysis of 172 states across the globe. The results from numerous negative binomial regression tests provide evidence supporting a statistically significant positive relationship between water scarcity and armed conflict; states having lower population percentages with access to improved water sources experience more instances of armed conflict – both interstate and intrastate. These findings prompt the conclusion that water scarcity is a significant predictor of armed conflict. As fresh water resources become increasingly limited across the globe, this study will continue to gain relevance, offering evidence to inform decisions about armed-conflict prevention in the international community

    Making a Difference in Schools: The Big Brothers Big Sisters School-Based Mentoring Impact Study

    Get PDF
    School-based mentoring is one of the fastest growing forms of mentoring in the US today; yet, few studies have rigorously examined its impacts. This landmark random assignment impact study of Big Brothers Big Sisters School-Based Mentoring is the first national study of this program model. It involves 10 agencies, 71 schools and 1,139 9- to 16-year-old youth randomly assigned to either a treatment group of program participants or a control group of their non-mentored peers. Surveys were administered to all participating youth, their teachers and mentors in the fall of 2004, spring of 2005 and late fall of 2005.The report describes the programs and their participants and answers several key questions, including: Does school-based mentoring work? What kinds of mentoring experiences help to ensure benefits? How much do these programs cost? Our findings highlight both the strengths of this program model and its current limitations and suggest several recommendations for refining this promising model-recommendations that Big Brothers Big Sisters agencies across the country are already working to implement

    Safety and immunogenicity of live viral vaccines in a multicenter cohort of pediatric transplant recipients

    IMPORTANCE: Live vaccines (measles-mumps-rubella [MMR] and varicella-zoster virus [VZV]) have not been recommended after solid organ transplant due to concern for inciting vaccine strain infection in an immunocompromised host. However, the rates of measles, mumps, and varicella are rising nationally and internationally, leaving susceptible immunocompromised children at risk for life-threating conditions. OBJECTIVE: To determine the safety and immunogenicity of live vaccines in pediatric liver and kidney transplant recipients. DESIGN, SETTING, AND PARTICIPANTS: This cohort study included select pediatric liver and kidney transplant recipients who had not completed their primary MMR and VZV vaccine series and/or who displayed nonprotective serum antibody levels at enrollment between January 1, 2002, and February 28, 2023. Eligibility for live vaccine was determined by individual US pediatric solid organ transplant center protocols. EXPOSURES: Exposure was defined as receipt of a posttransplant live vaccine. Transplant recipients received 1 to 3 doses of MMR vaccine and/or 1 to 3 doses of VZV vaccine. MAIN OUTCOME AND MEASURE: Safety data were collected following each vaccination, and antibody levels were obtained at 0 to 3 months and 1 year following vaccination. Comparisons were performed using Mann-Whitney U test, and factors associated with development of postvaccination protective antibodies were explored using univariate analysis. RESULTS: The cohort included 281 children (270 [96%] liver, 9 [3%] kidney, 2 [1%] liver-kidney recipients) from 18 centers. The median time from transplant to enrollment was 6.3 years (IQR, 3.4-11.1 years). The median age at first posttransplant vaccine was 8.9 years (IQR, 4.7-13.8 years). A total of 202 of 275 (73%) children were receiving low-level monotherapy immunosuppression at the time of vaccination. The majority of children developed protective antibodies following vaccination (107 of 149 [72%] varicella, 130 of 152 [86%] measles, 100 of 120 [83%] mumps, and 124 of 125 [99%] rubella). One year post vaccination, the majority of children who initially mounted protective antibodies maintained this protection (34 of 44 [77%] varicella, 45 of 49 [92%] measles, 35 of 42 [83%] mumps, 51 of 54 [94%] rubella). Five children developed clinical varicella, all of which resolved within 1 week. There were no cases of measles or rubella and no episodes of graft rejection within 1 month of vaccination. There was no association between antibody response and immunosuppression level at the time of vaccination. CONCLUSIONS AND RELEVANCE: The findings suggest that live vaccinations may be safe and immunogenic after solid organ transplant in select pediatric recipients and can offer protection against circulating measles, mumps, and varicella

    Surfaces, depths and hypercubes: Meyerholdian scenography and the fourth dimension

    Get PDF
    An appreciation of Meyerhold’s engagement with theatrical space is fundamental to understanding his directorial and pedagogic practice. This article begins by establishing Meyerhold’s theoretical and practical engagement with theatre as a fundamentally scenographic process, arguing for a reconceptualisation of the director as ‘director-scenographer’. Focusing on the construction of depth and surface in Meyerholdian theatre, the article goes on to identify trends in the director’s approach to space, with an emphasis on the de-naturalisation of depth on stage. This denaturalisation is seen as taking three forms: the rejection of depth as a prerequisite in theatrical space, the acknowledgement of the two-dimensional surface as surface, and the restructuring of depth space into a series of restricted planes. The combination of these trends indicates a consistent and systematic process of experimentation in Meyerhold’s work. In addition, this emphasis on depth and surface, and the interaction between the two, also highlights the contextualisation of Meyerhold’s practice within the visual, philosophical and scientific culture of the early twentieth century, echoing the innovations in n-dimensional geometry and particularly, the model of the fourth spatial dimension seen in the work of Russian philosopher P. D. Ouspensky
