    FDI in Space: Spatial Autoregressive Relationships in Foreign Direct Investment

    Theoretical models of foreign direct investment (FDI) have only recently begun to model the role of third countries, and the empirical FDI literature has almost exclusively examined bilateral FDI data without recognizing the potential interdependence between FDI decisions to alternative host countries. This paper uses spatial econometric techniques to examine the spatial correlation between FDI to alternative (neighboring) regions. The sign of such correlations can provide evidence for or against alternative theories for FDI motivations. Using data on OECD countries from 1980-2000, we find evidence consistent with export platform FDI in Europe.

    Radical Listening, Action, and Reflection at the Boundaries of Youth Violence Prevention

    The purpose of this article is to make visible collaborative pedagogical and research practices that opened space for community members to be co-educators and researchers with students and a professor on a youth violence assessment. We use Third Generation Cultural Historical Activity Theory (CHAT) as a conceptual framework to examine the learning that occurred in the boundary zone of our eight differently situated organizations. As we demonstrate through the inclusion of boundary dialogue excerpts, this process generated more authentic understandings of why racial inequity has persisted in youth violence outcomes. The assessment questions we asked, the key informants we engaged, the data analysis process we undertook, and the substantially different types of findings that emerged were a function of relationship building and radical listening in the boundary zone of our collaboration. We conclude that practices that foster radical listening in boundary work can reframe experiential learning for racial justice

    Designing a workplace return-to-work program for occupational low back pain: an intervention mapping approach

    <p>Abstract</p> <p>Background</p> <p>Despite over 2 decades of research, the ability to prevent work-related low back pain (LBP) and disability remains elusive. Recent research suggests that interventions that are focused at the workplace and incorporate the principals of <it>participatory ergonomics </it>and return-to-work (RTW) coordination can improve RTW and reduce disability following a work-related back injury. Workplace interventions or programs to improve RTW are difficult to design and implement given the various individuals and environments involved, each with their own unique circumstances. Intervention mapping provides a framework for designing and implementing complex interventions or programs. The objective of this study is to design a best evidence RTW program for occupational LBP tailored to the Ontario setting using an intervention mapping approach.</p> <p>Methods</p> <p>We used a qualitative synthesis based on the intervention mapping methodology. Best evidence from systematic reviews, practice guidelines and key articles on the prognosis and management of LBP and improving RTW was combined with theoretical models for managing LBP and changing behaviour. This was then systematically operationalized into a RTW program using consensus among experts and stakeholders. The RTW Program was further refined following feedback from nine focus groups with various stakeholders.</p> <p>Results</p> <p>A detailed five step RTW program was developed. The key features of the program include; having trained personnel coordinate the RTW process, identifying and ranking barriers and solutions to RTW from the perspective of all important stakeholders, mediating practical solutions at the workplace and, empowering the injured worker in RTW decision-making.</p> <p>Conclusion</p> <p>Intervention mapping provided a useful framework to develop a comprehensive RTW program tailored to the Ontario setting.</p

    Identification of unique neoantigen qualities in long-term survivors of pancreatic cancer

    Pancreatic ductal adenocarcinoma is a lethal cancer with fewer than 7% of patients surviving past 5 years. T-cell immunity has been linked to the exceptional outcome of the few long-term survivors1,2, yet the relevant antigens remain unknown. Here we use genetic, immunohistochemical and transcriptional immunoprofiling, computational biophysics, and functional assays to identify T-cell antigens in long-term survivors of pancreatic cancer. Using whole-exome sequencing and in silico neoantigen prediction, we found that tumours with both the highest neoantigen number and the most abundant CD8+ T-cell infiltrates, but neither alone, stratified patients with the longest survival. Investigating the specific neoantigen qualities promoting T-cell activation in long-term survivors, we discovered that these individuals were enriched in neoantigen qualities defined by a fitness model, and neoantigens in the tumour antigen MUC16 (also known as CA125). A neoantigen quality fitness model conferring greater immunogenicity to neoantigens with differential presentation and homology to infectious disease-derived peptides identified long-term survivors in two independent datasets, whereas a neoantigen quantity model ascribing greater immunogenicity to increasing neoantigen number alone did not. We detected intratumoural and lasting circulating T-cell reactivity to both high-quality and MUC16 neoantigens in long-term survivors of pancreatic cancer, including clones with specificity to both high-quality neoantigens and predicted cross-reactive microbial epitopes, consistent with neoantigen molecular mimicry. Notably, we observed selective loss of high-quality and MUC16 neoantigenic clones on metastatic progression, suggesting neoantigen immunoediting. Our results identify neoantigens with unique qualities as T-cell targets in pancreatic ductal adenocarcinoma. More broadly, we identify neoantigen quality as a biomarker for immunogenic tumours that may guide the application of immunotherapies

    Funder: NCI U24CA211006Abstract: The Cancer Genome Atlas (TCGA) and International Cancer Genome Consortium (ICGC) curated consensus somatic mutation calls using whole exome sequencing (WES) and whole genome sequencing (WGS), respectively. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, which aggregated whole genome sequencing data from 2,658 cancers across 38 tumour types, we compare WES and WGS side-by-side from 746 TCGA samples, finding that ~80% of mutations overlap in covered exonic regions. We estimate that low variant allele fraction (VAF < 15%) and clonal heterogeneity contribute up to 68% of private WGS mutations and 71% of private WES mutations. We observe that ~30% of private WGS mutations trace to mutations identified by a single variant caller in WES consensus efforts. WGS captures both ~50% more variation in exonic regions and un-observed mutations in loci with variable GC-content. Together, our analysis highlights technological divergences between two reproducible somatic variant detection efforts

    Electroexcitation of giant resonances between 5 MeV and 40 MeV excitation energy in 197 Au

    Inelastic scattering from(197)Au between 5 MeV and 40 MeV excitation energy revealed giant multipole resonances. Angular distribution studies with incident 90 MeV electrons show evidence of previously unreported giant monopole states. Reduced matrix elements have been extracted and multipolarity assignments have been made. Seven states have been observed at excitations of 7.3 (undetermined magnetic), 9.2 (E0), 10.8 (E2) , 14.0 (E1), 18.o (undetermined), 22.5 (E2), and 33.5 MeV (E0 or E2).http://archive.org/details/electroexcitatio00ferlEnsign, United States NavyLieutenant, United States NavyApproved for public release; distribution is unlimited
