Gender gaps and reentry into entrepreneurial ecosystems after business failure
Despite the significant role played by serial entrepreneurs in the entrepreneurial process, we know little about group differences in reentry decisions after business failure. Using an ecosystems framework and stigma theory, we investigate the variance in gender gaps related to the reentry decisions of 8,171 entrepreneurs from 35 countries who experienced business failures. We find evidence of persisting gender gaps that vary across ecosystem framework conditions of public stigma of business failure and public fear of business failure. Our findings shed new light on ecosystem inefficiencies that arise from multiple interactions between entrepreneurs and institutions
Human Respiratory Syncytial Virus Memphis 37 Causes Acute Respiratory Disease in Perinatal Lamb Lung
Respiratory syncytial virus is associated with an inflammatory response in lungs and architectural remodeling of lung-draining lymph nodes of newborn lambs
Respiratory syncytial virus (RSV) is the leading cause of lower respiratory tract infection in children worldwide. The understanding of neonatal RSV pathogenesis depends on using an animal model that reproduces neonatal RSV disease. Previous studies from us and others demonstrated that the neonatal lamb model resembles human neonatal RSV infection. Here, we provide an extensive and detailed characterization of the histopathology, viral load, cellular infiltration, and cytokine production in lungs and tracheobronchial lymph nodes of lambs inoculated with human RSV strain A2 over the course of infection. In the lung, RSV titers were low at day 3 postinfection, increased significantly by day 6, and decreased to baseline levels at day 14. Infection in the lung was associated with an accumulation of macrophages, CD4+ and CD8+ T cells, and a transcriptional response of genes involved in inflammation, chemotaxis, and interferon response, characterized by increased IFNγ, IL-8, MCP-1, and PD-L1, and decreased IFNβ, IL-10, and TGF-β. Laser capture microdissection studies determined that lung macrophage-enriched populations were the source of MCP-1 but not IL-8. Immunoreactivity to caspase 3 occurred within bronchioles and alveoli of day 6-infected lambs. In lung-draining lymph nodes, RSV induced lymphoid hyperplasia, suggesting an ability of RSV to enhance lymphocytic proliferation and differentiation pathways. This study suggests that, in lambs with moderate clinical disease, RSV enhances the activation of caspase cell death and Th1-skewed inflammatory pathways, and complements previous observations that emphasize the role of inflammation in the pathogenesis of RSV disease

The Role of Gratitude in Breast Cancer: Its Relationships with Post-traumatic Growth, Psychological Well-Being and Distress
Despite the increasing number of studies documenting the positive effects of gratitude in coping with traumatic events and facilitating psychological well-being, none is addressed to patients with life-threatening illnesses such as cancer. The aims of this study are to examine the role of gratitude in a breast cancer sample and its correlations with post-traumatic growth, psychological well-being, and distress; and to compare patients reporting higher levels of gratitude (High Gratitude Individuals, HGI) versus those reporting lower levels (Low Gratitude Individuals, LGI). 67 breast cancer patients were assessed with: (1) Gratitude Questionnaire; (2) Post-traumatic Growth Inventory (PTGI); (3) Psychological Well-being Scales (PWBS) (4) Symptom Questionnaires (SQ); and were divided into: (1) High Gratitude Individuals-HGI (n = 27); (2) Low Gratitude Individuals-LGI (n = 40). Bivariate correlations between questionnaires and ANOVA between-group were calculated. Gratitude was significantly and positively correlated to all of PTGI scales, to PWBS positive relations, to SQ relaxation and contentment, and negatively related to anxiety, depression, and hostility-irritability. HGI and LGI reported significant differences on the PTGI and SQ dimensions, but not on PWB scales, with HGI displaying higher levels of PTGI, positive affect and lower symptomatology. Also in breast cancer patients gratitude is strongly associated to post-traumatic growth, reduced distress and increased positive emotions, but surprisingly not to psychological well-being. Since the majority of patients reported low gratitude levels, the results suggest the importance of developing interventions to clinically increase them also in oncology
