Coupling attributional and consequential life cycle assessment:A matter of social responsibility

A long-running debate within the life cycle assessment literature concerns the appropriate uses for attributional and consequential forms of life cycle assessment. A recently published contribution to this debate suggests that social responsibility necessarily requires a consequential perspective, and that taking an attributional perspective is optional, but not necessary. The present paper critiques this suggestion by exploring two limitations with only taking a consequential perspective. First, consequential assessments are not additive, in the sense that when added they do not approximate to total aggregate environmental burdens. Second, consequential assessments are not suitable for creating an initial scope of responsibility, as the number of possible decisions available to an agent may be intractably large, and the notion of ‘role’ responsibility is not defined by specific decisions and consequences. This second limitation is derived from a previously identified parallel between attributional and consequential methods and the normative ethical theories of deontology and consequentialism. Based on the exploration of the two limitations, a coupled accounting solution is proposed which uses both consequential and attributional approaches for different but complementary purposes. The paper concludes by suggesting that although the debate on attributional versus consequential methods has occurred largely within the field of life cycle assessment, the proposed coupled accounting solution has broader applicability to other areas of social and environmental accounting.The first author would like to acknowledge the UK’s Economic and Social Research Council, in partnership with the Society for the Advancement of Management Studies (SAMS) and the UK Commission for Employment and Skills (UKCES), for their support through the Management and Business Development Fellowship Scheme, and also Macquarie University for a Visiting Fellowship, and Mona Vale Library

Modern slavery disclosures in mining: a comparison of large UK and Australian companies

With growing interest in eradication of modern slavery in operations and supply chains the purpose of the paper is to explore disclosures of the top ten listed mining companies in the UK and Australia. Institutional theory provides the foundation for a first examination of comparative modern slavery disclosures in these two countries, at the time one with and one without disclosure legislation. Based on qualitative thematic analysis, major results indicate the UK Modern Slavery Act 2015 to be a catalyst for disclosures made by the sample of UK mining companies, whereas in Australia where no modern slavery legislation was in place, normative and mimetic institutional pressure is not viewed as important and the companies seemed underprepared for impending legislative changes. The paper concludes that transparency based legislation on modern slavery can provide a powerful coercive influence for change, strengthening other forms of normative and mimetic pressure

Diffuse Axonal Injury: A Devastating Pathology

Traumatic brain injury (TBI) also known as intracranial injury is the result of a lesion within the brain due to an external force. Common forms of TBI result from falls, violence, and/or vehicle crashes; the classification of this pathology is dependent on the severity of the lesion as well as the mechanism of trauma to the head. One of the most common onsets of traumatic brain injuries result from mild to severe lesions to the white matter tracts of the brain called diffuse axonal injury (DAI); however, additional forms of TBI’s can present in non-penetrating forms. Penetrating forms of TBI’s such as trauma to the head via a foreign object do also contribute to the many millions of TBI cases per year, but we will not discuss these traumatic injuries as in depth within this chapter. The onset of diffuse axonal injury will vary on a per-patient basis from mild to severe, based on a standardized neurological examination rated on the Glasgow Coma Scale (GCS), which indicates the severity of brain damage present. While there is a spectrum of severity for DAI patients, a concussion is typically observed within a larger majority of patients in addition to other overwhelming trauma

Historical Threads in the Development of Oncology Social Work

As the Association of Oncology Social Work celebrates its 25th year, we pause to reflect on the many historical threads that contributed to its development and hear from each of the presidents who helped create the organization, as we know it today. Set within hospitals, medical social work was born in the early 20th century. In the 1940s medical social work became necessary for hospital accreditation. Two additional historical shifts, one in medical improvements in treating cancer, the other a shift to a consumer-oriented American Cancer Society, contributed to the push for a greater role for the federal government in funding cancer research. Oncology social work came to full blossom in the 1970s, a result of the physicians' need for a member of the health care team who understood cancer, its treatment, and the patient's need to address his or her psychosocial needs resulting from cancer. Today, oncology social work is a fully developed profession with a national organization providing education and support to oncology social workers' in their use of psychosocial interventions and research in behalf of cancer patients and their families

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

Integrated genomic characterization of pancreatic ductal adenocarcinoma

We performed integrated genomic, transcriptomic, and proteomic profiling of 150 pancreatic ductal adenocarcinoma (PDAC) specimens, including samples with characteristic low neoplastic cellularity. Deep whole-exome sequencing revealed recurrent somatic mutations in KRAS, TP53, CDKN2A, SMAD4, RNF43, ARID1A, TGFβR2, GNAS, RREB1, and PBRM1. KRAS wild-type tumors harbored alterations in other oncogenic drivers, including GNAS, BRAF, CTNNB1, and additional RAS pathway genes. A subset of tumors harbored multiple KRAS mutations, with some showing evidence of biallelic mutations. Protein profiling identified a favorable prognosis subset with low epithelial-mesenchymal transition and high MTOR pathway scores. Associations of non-coding RNAs with tumor-specific mRNA subtypes were also identified. Our integrated multi-platform analysis reveals a complex molecular landscape of PDAC and provides a roadmap for precision medicine

Many Labs 5:Testing pre-data collection peer review as an intervention to increase replicability

Replication studies in psychological science sometimes fail to reproduce prior findings. If these studies use methods that are unfaithful to the original study or ineffective in eliciting the phenomenon of interest, then a failure to replicate may be a failure of the protocol rather than a challenge to the original finding. Formal pre-data-collection peer review by experts may address shortcomings and increase replicability rates. We selected 10 replication studies from the Reproducibility Project: Psychology (RP:P; Open Science Collaboration, 2015) for which the original authors had expressed concerns about the replication designs before data collection; only one of these studies had yielded a statistically significant effect (p < .05). Commenters suggested that lack of adherence to expert review and low-powered tests were the reasons that most of these RP:P studies failed to replicate the original effects. We revised the replication protocols and received formal peer review prior to conducting new replication studies. We administered the RP:P and revised protocols in multiple laboratories (median number of laboratories per original study = 6.5, range = 3?9; median total sample = 1,279.5, range = 276?3,512) for high-powered tests of each original finding with both protocols. Overall, following the preregistered analysis plan, we found that the revised protocols produced effect sizes similar to those of the RP:P protocols (?r = .002 or .014, depending on analytic approach). The median effect size for the revised protocols (r = .05) was similar to that of the RP:P protocols (r = .04) and the original RP:P replications (r = .11), and smaller than that of the original studies (r = .37). Analysis of the cumulative evidence across the original studies and the corresponding three replication attempts provided very precise estimates of the 10 tested effects and indicated that their effect sizes (median r = .07, range = .00?.15) were 78% smaller, on average, than the original effect sizes (median r = .37, range = .19?.50)

Retrospective evaluation of whole exome and genome mutation calls in 746 cancer samples

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
