A framework to evaluate the effects of organizational resilience on service quality

Disruptions and unexpected turbulences characterize the contemporary service industry and pose greater criticalities to organizations that have concerns about both their survival and their business sustainability. The answer to this challenge is to design an organizational system aimed at enhancing so-called organizational resilience. The aim of this work is to present and test an assessment methodology based on a framework that links key static and dynamic characteristics of firms as resilient systems and relates these characteristics with service quality preservation after disruptions. The framework adopts a set of indicators, namely resilience dimensions, to comprehend the real effects of resilience characteristics with service quality dimensions. Through the analysis of a real case, we provided evidence of how the model can be applied in a backward perspective to understand fault modes of specific events. Results show how inadequacies in terms of resilience characteristics determine losses of service quality, and also how the model can be used as a predictive tool to determine in which area companies should intervene in order to improve resilience and service quality

Physical activity and cancer prevention: a review of current evidence and biological mechanisms

Objective. The main aim of this paper is to review the evidence available from the date of PubMed?s inception to May 2011 for a link between cancer and physical activity (PA) in both animal models and humans. Methods. We decided to select studies that comply with the scheme proposed by the American College of Sports Medicine/ American Heart Association (ACSM/AHA) that distinguish occupational physical activity (OPA) and leisure-time physical activity (LT-PA), further classified in three levels of intensity (low, moderate and heavy) based on the Metabolic Equivalent of Task (MET) index. Results. Considering animal models, there was strong evidence for an inverse association between voluntary wheel exercise and the risk of colon and breast cancer. Regarding human studies, we identified the following main results: 1) colorectum: LT-PA provided an overall colon risk reduction of 13-14%; 2) breast: significant reduction in the frequency of post-menopausal (PMP) cancers in women that practiced heavy and moderate LT-PA; 3) prostate: heavy OPA and LT-PA seemed to reduce the risk of advanced prostate cancers; 4) endometrium: strong protective effect of heavy/moderate LT-PA among overweight/ obese women; 5) lung: inverse relationship between heavy LT-PA and lung cancer in former or current smokers across all histologies. Conclusion. Increased LT-PA is associated with cancer prevention in several organs, but strong biases, such as body mass index (BMI), gender and age, make it difficult to assess which aspects of PA contribute most strongly to the reduced risk. Furthermore, we found few studies that indicated a protective role for OPA in cancer prevention when compared with LT-PA

Stories of Southern Oregon = Communities + Libraries + Museums + University

Collaborations often have the best outcomes because conversations among those with diverse experiences, varied institutional affiliations, and cross-discipline training bring breadth and depth of perspective. The Stories of Southern Oregon project was a good example of how libraries, museums, and academics can work together to surface important historical content, build community, and strengthen relationships. Thanks to a 2017 grant from the National Endowment for the Humanities’ Common Heritage program, Southern Oregon University faculty partnered with the Eagle Point and Ruch branches of the Jackson County Library District and local museums to collect stories and images of heritage work-life like logging, mining, farming, and ranching. Memories of a different time are very much alive in the rural towns of Jackson and Josephine counties, and public libraries and museums are central to the collective heritage of our small communities. This article describes the Stories of Southern Oregon project and how public libraries in Ruch and Eagle Point engaged their communities to bring history to life, and make a real difference to those they serve every day

Framing open innovation in start-ups' incubators: A complexity theory perspective

Recently, concepts and principles from the Complexity Theory (or, generally speaking, the complexity sciences) have been applied as a perspective for capturing the influence of the context, interaction, and adaption in the innovation processes, such as the ones enabled in the business incubators. The purpose of this paper is to implement a frame of reference for understanding the start-ups’ incubator as a complex system where innovation, learning, and self-organization take place. We build on the interfaces between the Complexity Theory (i.e., complexity sciences) and Open Innovation literature to identify principles, patterns, and conditions that frame the incubation practices as simple rules aimed to sustain the innovation process towards the creation of new ventures. Results from the multiple case studies conducted in five incubators show that the features of variety, nonlinear interaction, interdependence, autonomy, and emergence of the incubation process framed as a complex system are enabled in different ways by the combination of the open innovation practices and services provided by the start-ups’ incubators, including the provision of physical infrastructure, access to funding streams, experts/entrepreneurs networking, education/workshops, mentorship, and advice

Alexithymia, impulsiveness, and psychopathology in Nonsuicidal self-injured adolescents

Introduction: Nonsuicidal self-injury (NSSI) is a multifaceted phenomenon and a major health issue among adolescents. A better understanding of self-injury comorbidities is crucial to improve our ability to assess, treat, and prevent NSSI. Purpose: This study aimed at analyzing some of the psychobehavioral correlates of NSSI: psychological problems, alexithymia, impulsiveness, and sociorelational aspects. Patients and methods: This was a case-control study. The clinical sample (n=33) included adolescents attending our unit for NSSI and other issues; the controls (n=79) were high-school students. Data were collected using six questionnaires: Youth Self-Report, Barratt\u2019s Impulsiveness Scale, Toronto Alexithymia Scale, Children\u2019s Depression Inventory, Symptom Checklist-90-R, and Child Behavior Checklist. Results: Cases scored significantly higher in all questionnaires. Habitual self-injurers scored higher on impulsiveness and alexithymia. The gesture\u2019s repetition seems relevant to the global clinical picture: habitual self-injurers appear more likely to seek help from the sociosanitary services. We found a difference between the self-injurers\u2019 and their parents\u2019 awareness of the disorder. Conclusion: Habitual self-injurers show signs of having difficulty with assessing the consequences of their actions (nonplanning impulsiveness) and the inability to manage their feelings. Given the significantly higher scores found for cases than for controls on all the psychopathological scales, NSSI can be seen as a cross-category psychiatric disorder, supporting the Diagnostic and Statistical Manual of Mental Disorders decision to include it as a pathological entity in its own right

Absences from work among healthcare workers: are they related to influenza shot adherence?

BACKGROUND: The coverage for influenza vaccination among healthcare workers (HCWs) is inadequate in many countries despite strong recommendations; is there evidence that influenza vaccination is effective in preventing absenteeism? Aim of the study is to evaluate the influenza vaccination coverage and its effects on absences from work among HCWs of an Italian academic healthcare trust during the 2017-2018 influenza season. METHODS: We performed a retrospective study to identify predictive characteristics for vaccination, and a retrospective cohort study to establish the effect of vaccination on absences among the vaccinated and non-vaccinated cohorts between December 2017 and May 2018. Overall absence rates over the whole observation period and sub-rates over 14-days intervals were calculated; then comparison between the two groups were conducted applying Chi-square test. RESULTS: Influenza vaccination coverage among 4419 HCWs was 14.5%. Age, university degree, medical care area and physician profile were positively associated with vaccine uptake. Globally during influenza season non-vaccinated HCWs lost 2.47/100 person-days of work compared to 1.92/100 person-days of work among vaccinated HCWs (p\u2009<\u20090.001); significant differences in absences rates resulted when focusing on the influenza epidemic peak. CONCLUSIONS: Factors predicting influenza uptake among HCWs were male sex, working within medical care area and being a physician. Absenteeism among HCWs resulted to be negatively correlated with vaccination against influenza. These findings add evidence to the urgent need to implement better influenza vaccination strategies towards HCWs to tackle vaccine hesitancy among professionals

Application of light-sheet mesoscopy to image host-pathogen interactions in intact organs

Human African Trypanosomiasis (HAT) is a disease caused by the extracellular parasite Trypanosoma brucei that affects the central nervous system (CNS) during the chronic stage of the infection, inducing neuroinflammation, coma, and death if left untreated. However, little is known about the structural change happening in the brain as result of the infection. So far, infection-induced neuroinflammation has been observed with conventional methods, such as immunohistochemistry, electron microscopy, and 2-photon microscopy only in small portions of the brain, which may not be representative of the disease. In this paper, we have used a newly-developed light-sheet illuminator to image the level of neuroinflammation in chronically infected mice and compared it to naïve controls. This system was developed for imaging in combination with the Mesolens objective lens, providing fast sub-cellular resolution for tens of mm3-large imaging volumes. The mouse brain specimens were cleared using CUBIC+, followed by antibody staining to locate Glial Fibrillary Acid Protein (GFAP) expressing cells, primarily astrocytes and ependymocytes, used here as a proxy for cell reactivity and gliosis. The large capture volume allowed us to detect GFAP+ cells and spatially resolve the response to T. brucei infection. Based on morphometric analyses and spatial distribution of GFAP+ cells, our data demonstrates a significant increase in cell dendrite branching around the lateral ventricle, as well as dorsal and ventral third ventricles, that are negatively correlated with the branch extension in distal sites from the circumventricular spaces. To our knowledge, this is the first report highlighting the potential of light-sheet mesoscopy to characterise the inflammatory responses of the mouse brain to parasitic infection at the cellular level in intact cleared organs, opening new avenues for the development of new mesoscale imaging techniques for the study of host-pathogen interactions

How social start-ups avoid being falling stars when developing social innovation

The aim of this study is to provide new insights into the social innovation (SI) development process in the context of social start-ups. A multiple case study identifies the issues and mechanisms for social start-ups to develop a social need into a potentially scalable innovation and to validate and scale it up, while avoiding a possible failure. Results show that key challenges faced by social start-ups can be characterized according to the stage of the SI development path. Firstly, social start-ups' failure can be caused by the lack of expertise in social problems and of flexible processes for social ventures creation; secondly, by the lack of awareness of SI benefits and proper resources allocation; and, finally, by a weak understanding of the impact and intangible outcomes of the developed SI in society, while ensuring its economic sustainability. Successfully overcoming these challenges requires social start-ups to put in place the following mechanisms: (1) leveraging a vision and motivations that balance tensions in terms of the radical, economic and cultural aspects of SI; (2) engaging the SI stakeholders in different (and sequential) phases of SI development process; and (3) identifying and adopting the most suitable technological, financial and communication tools in an integrated way
