    Entrepreneurial narrative identity and gender:a double epistemological shift

    Get PDF
    A double epistemological shift is proposed to challenge the enduring dominance of the discourse of entrepreneurial masculinity, which impedes our understanding of entrepreneurship. First, a reframing of the epistemological status of narrative supports philosophical and theoretical approaches to the constitution of narrative identity. Second, an epistemological shift to understand gender in entrepreneurship through the constitution of gendered identities in discourse is proposed. These shifts invoke the ontological dimension of narrative and contemporary theories of gender to understand entrepreneurial identity as co-constituted and located in repertoires of historically and culturally situated narrative. This offers new theoretical and methodological possibilities in entrepreneurship

    How family business members learn about continuity

    Get PDF
    Continuity is about connection and cohesion over time. A defining question in the study of family business is how the family and the business can endure and survive across generations. Learning about continuity is fundamental in addressing that question. This study explores how family business members learn about continuity. It draws on concepts of communities of practice and legitimate peripheral participation derived from Lave and Wenger’s (1991) situated learning perspective. These are used as theoretical lenses to explore the relationship between family members and learning through an interpretive and inductive study of 18 respondents from family businesses in Canada. This study shows learning in the family business context is about continuity, but the process of learning in which the family engages is uneven, non-linear, and unpredictable. To deal with these complexities and learn about continuity, family members participate in multiple ways, often gradually over time. In this study gradual participation to build legitimacy is revealed as a multi-generational learning phenomenon. It involves multiple forms of co-participation influenced by family members from the past, present and future

    This report describes research carried out by the Equality, Diversity and Inclusivity (EDI) team at UWE Bristol to understand the lived experience of mature students, aged 21 or over on entry to their Undergraduate degree. The research sought to understand whether mature students at UWE Bristol faced the same barriers as those found in the literature by exploring the following questions:1.What is the lived experience of mature Undergraduate students at UWE Bristol? 2.How well does the University and Students’ Union support mature students?3.How do students feel this support could be improved?This study investigated the experience of mature students through a series of focus groups. Participants were a self-selecting sample and were initially asked to complete a sign-up survey to register their interest and select their availability for a focus group. In total, 64 students completed the sign-up survey and 8 focus group sessions were scheduled, to allow for participant drop out. In February and March 2020 6 focus groups took place with a total of 17 participants. The final two focus groups were cancelled due to the closure of the university campus so an online survey was sent to the remaining participants containing similar questions. The survey had 22 responses, bringing the total number of participants to 39.The findings showed that participants had experienced challenges in adjusting to study that typically wouldn’t be faced by those coming to university straight from school or college. Mature students who had been out of education for a long time often felt they lacked study skills and found it difficult adjusting to student life. Many struggled to balance other commitments, notably childcare and paid work, with study. As a result, mature students were often less able to engage socially with their coursemates and take up extracurricular opportunities. Differences in outlook between mature and young students was another barrier to integration between the two groups. Participants’ experiences of support varied. Several commented that they found it difficult to locate support when they needed it and felt that the range of services available could be better promoted. However, once they had accessed the support, mature students’ experience of it was usually positive and they felt generally well supported by the university. As well as smaller improvements to existing services, the focus groups identified three key areas where additional support could be provided:‱Tailored induction activities and social activities for mature students‱Tailored accommodation support for mature students‱Tailored careers and placement support for mature studentsRecommendationsA total of 8 recommendations have come from this research:Pre-enrolment 1.Increase the use of mature students in imagery and use student comms to highlight the proportion of UWE students who start their studies later in life2.University and SU to review access to childcare for student parents and ensure the options are clearly communicatedInduction3.Tailored induction sessions for mature students and those who have spent time out of education4.Increase the number of freshers’ events aimed at mature studentsStudent experience 5.Review accommodation support offer for mature students and ways to integrate students living in private-rented6.SU to review and promote mature student society7.Clearer communication of all support options available to mature students at UWE 8.Tailored careers support for mature students who may be studying to pursue a career change and those wishing to access internships/placement

    Spondylarthropathies (including psoriatic arthritis): 244. Validity of Colour Doppler and Spectral Doppler Ultrasound of Sacroilicac Joints Againts Physical Examination as Gold Standard

    Get PDF
    Background: Sacroiliac joints (SJ) involvement is a distinctive and charasteristic feature of Spondyloarthritis (SpA) and x-ray is the test routinely used to make a diagnosis. However, x-ray reveals late structural damage but cannot detect active inflammation. The objective of this study was to assess the validity of Doppler ultrasound in SJ. Methods: Prospective blinded and controlled study of SJ, in which three populations were compared. We studied 106 consecutive cases, who were divided into three groups: a) 53 patients diagnosed with SpA who had inflammatory lumbar and gluteal pain assessed by a rheumatologist; b) 26 patients diagnosed with SpA who didn't have SJ tenderness and had normal physical examination; c) control group of 27 subjects (healthy subjetcs or with mechanical lumbar pain). All patients included that were diagnosed with SpA met almost the European Spondyloarthropathy Study Group (ESSG) classification criteria. Physical examination of the SJ included: sacral sulcus tenderness, iliac gapping, iliac compression, midline sacral thrust test, Gaenslen's test, and Patrick s test were used as gold standard. Both SJ were examined with Doppler ultrasound (General Electric Logiq 9, Wauwatosa WI, USA) fitted with a 9-14 Mhz lineal probe. The ultrasonographer was blinded to clinical data. Doppler in SJ was assessed as positive when both Doppler colour and resistance index (RI) < 0.75 within the SJ area were present. Statistical analysis was performed estimating sensitivity and specificity against gold standard. The Kappa correlation coefficient was used for reliability study. Results: 106 cases (53 female, 55 male; mean age 36 10 years) were studied. There were no statistical differences between groups related to age or sex. Physical examination of SJ was positive in 38 patients (59 sacroiliac joints). US detected Doppler signal within SJ in 37 patients (58 SJ): 33 of them were symptomatic SpA (52 SJ), one of them were asymptomatic SpA (1 SJ) and one was a healthy control (1 SJ). The accuracy of US when compared to clinical data as gold standard at subject level in the overall group was: sensitivity of 68.6% and specificity of 85.7%, positive predictive value of 70.5% and negative predictive value of 84.5%. A positive likelihood ratio of 4.8, a negative likelihood ratio of 0.36 and a kappa coefficient of 0.55 were achieved. Conclusions: Doppler US of SJ seems to be a valid method to detect active SJ inflammation. Disclosure statement: The authors have declared no conflicts of interes

    Participation in collaborative fisheries research improves the perceptions of recreational anglers towards marine protected areas

    Get PDF
    Collaborative fisheries research programs engage stakeholders in data collection efforts, often with the benefit of increasing transparency about the status and management of natural resources. These programs are particularly important in marine systems, where management of recreational and commercial fisheries have historically been contentious. One such program is the California Collaborative Fisheries Research Program (CCFRP), which was designed in 2006 to engage recreational anglers in the scientific process and evaluate the efficacy of California’s network of marine protected areas. CCFRP began on the Central Coast of California and expanded statewide in 2017 to include six partner institutions in three regions: Northern, Central, and Southern California. To date, over 2,000 volunteer anglers have participated in the program, with many anglers volunteering for multiple years. However, the impacts of outreach, education, and collaborative research on those anglers at the statewide scale are currently unknown. Thus, the objective of the current study was to survey the statewide pool of volunteer anglers to assess the degree to which participation in CCFRP has influenced angler perceptions of MPAs, fisheries management, and conservation. We received 259 completed surveys out of a pool of 1,386 active anglers, equating to an 18.7% response rate. Participation in CCFRP resulted in a significant, positive impact on anglers’ attitudes towards MPAs in California across all regions. Anglers who participated in six or more CCFRP fishing trips had a more positive perception of MPAs than those who participated in fewer trips. Volunteer anglers across all regions perceived that they caught larger fishes, a higher abundance of fishes, and a greater diversity of species inside MPAs, consistent with the ecological findings of the program. These results highlight the benefits of involving community members in collaborative scientific research. Collaboration between researchers and the broader community increases transparency and trust between stakeholders, and results in greater understanding of natural resource dynamics, ultimately producing better management outcomes

    Non-coding genetic variants play an important role in driving susceptibility to complex diseases but their characterization remains challenging. Here, we employed a novel approach to interrogate the genetic risk of such polymorphisms in a more systematic way by targeting specific regulatory regions relevant for the phenotype studied. We applied this method to meningococcal disease susceptibility, using the DNA binding pattern of RELA - a NF-kB subunit, master regulator of the response to infection - under bacterial stimuli in nasopharyngeal epithelial cells. We designed a custom panel to cover these RELA binding sites and used it for targeted sequencing in cases and controls. Variant calling and association analysis were performed followed by validation of candidate polymorphisms by genotyping in three independent cohorts. We identified two new polymorphisms, rs4823231 and rs11913168, showing signs of association with meningococcal disease susceptibility. In addition, using our genomic data as well as publicly available resources, we found evidences for these SNPs to have potential regulatory effects on ATXN10 and LIF genes respectively. The variants and related candidate genes are relevant for infectious diseases and may have important contribution for meningococcal disease pathology. Finally, we described a novel genetic association approach that could be applied to other phenotypes

    Host-mediated lung inflammation is present1, and drives mortality2, in the critical illness caused by coronavirus disease 2019 (COVID-19). Host genetic variants associated with critical illness may identify mechanistic targets for therapeutic development3. Here we report the results of the GenOMICC (Genetics Of Mortality In Critical Care) genome-wide association study in 2,244 critically ill patients with COVID-19 from 208 UK intensive care units. We have identified and replicated the following new genome-wide significant associations: on chromosome 12q24.13 (rs10735079, P = 1.65 × 10-8) in a gene cluster that encodes antiviral restriction enzyme activators (OAS1, OAS2 and OAS3); on chromosome 19p13.2 (rs74956615, P = 2.3 × 10-8) near the gene that encodes tyrosine kinase 2 (TYK2); on chromosome 19p13.3 (rs2109069, P = 3.98 ×  10-12) within the gene that encodes dipeptidyl peptidase 9 (DPP9); and on chromosome 21q22.1 (rs2236757, P = 4.99 × 10-8) in the interferon receptor gene IFNAR2. We identified potential targets for repurposing of licensed medications: using Mendelian randomization, we found evidence that low expression of IFNAR2, or high expression of TYK2, are associated with life-threatening disease; and transcriptome-wide association in lung tissue revealed that high expression of the monocyte-macrophage chemotactic receptor CCR2 is associated with severe COVID-19. Our results identify robust genetic signals relating to key host antiviral defence mechanisms and mediators of inflammatory organ damage in COVID-19. Both mechanisms may be amenable to targeted treatment with existing drugs. However, large-scale randomized clinical trials will be essential before any change to clinical practice

    Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19

    IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19. Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19. DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022). INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days. MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes. RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively). CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.
