Building an outward-oriented social family legacy: rhetorical history in family business foundations

Scholars have recently paid growing attention to the transfer of family legacies across generations, but existing work has been mainly focused on an inward-oriented, intra-family, perspective. In this article, we seek to understand how family firms engage in rhetorical history to transfer their social family legacy to external stakeholders, what we call “outward-oriented social legacy.” By carrying out a 12-months field study in three Italian family business foundations, our findings unveil three distinctive narrative practices—founder foreshadowing, emplacing the legacy within the broader community, and weaving family history with macro—history—that contribute to transferring outward-oriented social legacies

Vitamin D Deficiency in Autism Spectrum Disorder: A Cross-Sectional Study

Vitamin D plays a role in central nervous system (CNS) development. Recent literature focused on Vitamin D status in children and adolescents with autism spectrum disorder (ASD), but with inconsistent results. Our case-control study is aimed at evaluating serum 25-hydroxyl-Vitamin D (25(OH)D) concentration in children with ASD (ASD group, n=54) compared to children affected by other neurological and psychiatric disorders (non-ASD group, n=36). All patients were admitted at the Complex Operative Unit of Child Neuropsychiatry, Polyclinic of Bari, Italy. 25(OH)D was quantified by chemiluminescence immunoassay and level defined as: Deficiency (<20 ng/mL); insufficiency (20-30); normality (30-100); toxicity (>100). Statistical analysis was performed using SPSS20 (significance<0.05). The ASD group showed 25(OH)D a mean level significantly lower than control (p=0.014). Multivariable logistic regression analysis showed an association between ASD and Vitamin D deficiency (p=0.006). The nature of such association is unclear. Vitamin D deficiency may probably act as a risk factor for the development of ASD. Further studies are needed to unravel the role of Vitamin D in ASD etiology and investigate its therapeutic potential

Glucose Metabolism, Thyroid Function, and Prolactin Level in Adolescent Patients With First Episode of Schizophrenia and Affective Disorders

Schizophrenia and affective spectrum disorders (ASD) typically begin in adolescence or early adulthood. The pathophysiological mechanisms underlying these disorders are still not fully understood, and recent studies have suggested an involvement of dysfunctions in cardiometabolic and neuroendocrine systems at the onset of both disorders. In this context, we aimed to assess thyroid function, prolactin level, glucose metabolism, and lipid profile in drug naive adolescents, comparing patients with first episode of schizophrenia spectrum disorders (SSD) and patients with ASD. We performed a retrospective chart review from inpatients aged from ten to eighteen years, referred to Child and Adolescent Psychiatric Unit of University of Bari “Aldo Moro” over a period of 4 years, with diagnosis of SSD (n=30) or ASD (n=22), according to Diagnostic and Statistical Manual for Mental Disorders-fifth edition (DSM-5) criteria. Data on serum prolactin, glucose, insulin, total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol, triglycerides, thyroid stimulating hormone, free triiodothyronin, and free thyroxin were collected, and the insulin resistance (IR) indexes “HOMA1-IR“ and “HOMA2-IR” were calculated. The multivariable linear regression models, adjusting for potential confounding factors (age, sex, and BMI), showed HOMA1-IR (p=0.001), HOMA2-IR (p=0.002), glucose (p=0.004), insulin (p=0.004) and free thyroxin (p<0.001) values higher in the SSD group than in ASD. No others significant differences were found. Our findings suggest the need for a metabolic and endocrine screening at the onset of SSD and ASD, particularly for indexes of IR, that is a testable and treatable risk factor for cardiometabolic diseases. Further studies are required to better understand the role of endocrinological and metabolic dysfunctions at the onset of severe mental illness also considering influencing factors as age, gender, and BMI

B and T Immunoregulation: A New Insight of B Regulatory Lymphocytes in Autism Spectrum Disorder

Introduction: Autism Spectrum Disorder (ASD) is a heterogeneous neurodevelopmental disorder characterized by a complex pathogenesis, by impairment social communication and interaction, and may also manifest repetitive patterns of behavior. Many studies have recognized an alteration of the immune response as a major etiological component in ASDs. Despite this, it is still unclear the variation of the function of the immune response. Aim: Our aim is to investigate the levels of immunological markers in peripheral blood of children with ASD such as: regulatory B and T cells, memory B and natural killer (NK) cells. Materials and Methods: We assessed various subsets of immune cells in peripheral blood (regulatory B and T cells, B-cell memory and natural killer cells) by multi-parametric flow cytometric analysis in 26 ASD children compared to 16 healthy controls (HCs) who matched age and gender. Results: No significant difference was observed between B-cell memory and NK cells in ASDs and HCs. Instead, regulatory B cells and T cells were decreased (p < 0.05) in ASD subjects when compared to HCs. Discussion: Regulatory B and T cells have a strategic role in maintaining the immune homeostasis. Their functions have been associated with the development of multiple pathologies especially in autoimmune diseases. According to our study, the immunological imbalance of regulatory B and T cells may play a pivotal role in the evolution of the disease, as immune deficiencies could be related to the severity of the ongoing disorder

Opening up the black box of family entrepreneurship across generations : A systematic literature review

What makes some families more entrepreneurial than others? How are they able to nurture entrepreneurship across generations? These are fundamental questions for family business and entrepreneurship research. In particular, the multigenerational dimension of entrepreneurial families (EFs) and the new family logics that emerge as the family grows may lead to different types of entrepreneurial activities. To shed light on these questions, we conduct a systematic literature review of 90 peer-reviewed articles focusing on the characteristics and behaviours of EFs, family members and their business activities. Specifically, we first identify and categorise the family-related factors characterising EFs across generations. Second, we link the identified factors to different types of entrepreneurial activities pursued as the generations advance, distinguishing two dimensions: mode of organising (internal vs. external), and degree of relatedness (related vs. unrelated). Finally, we highlight the main gaps in the literature and provide a future research agenda

DRD1 and DRD2 Receptor Polymorphisms: Genetic Neuromodulation of the Dopaminergic System as a Risk Factor for ASD, ADHD and ASD/ADHD Overlap

The dopaminergic system (DS) is one of the most important neuromodulator systems involved in complex functions that are compromised in both autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD), conditions that frequently occur in overlap. This evidence suggests that both disorders might have common neurobiological pathways involving the DS. Therefore, the aim of this study was to examine the DRD1 and DRD2 dopamine receptor single nucleotide polymorphisms (SNPs) as potential risk factors for ASD, ADHD, and ASD/ADHD overlap. Genetic data were obtained from four groups: 75 ASD patients, 75 ADHD patients, 30 patients with ASD/ADHD overlap, and 75 healthy controls. All participants were between 2 and 17 years old. We compared the genotypic and allelic frequency of 18 SNPs among all of the study groups. Moreover, in the case of statistically significant differences, odds ratios (OR) were obtained to evaluate if the presence of SNPs might be a risk factor of developing a specific clinical phenotype. This study found that DRD1 and DRD2 receptors SNPs might be considered as potential risk factors for ASD and ADHD. However, only DRD2-12 (rs7131465) was significantly associated with a higher risk for the ASD/ADHD overlap. These data support the hypothesis of the genetic neuromodulation of the DS in the neurobiology of these conditions

The role of universities in the knowledge management of smart city projects

The development of smart cities is becoming more and more based on knowledge management (KM) frameworks. This leads to new managerial challenges, which reflect the complexity of KM governance and processes issues of smart city projects as well as the need to manage knowledge that originates both within and beyond projects' boundaries. However, in-depth research on the development of smart cities from a managerial and KM perspective has remained scant. In detail, although universities are deemed to be responsible for the competitiveness and superiority of knowledge-based ecosystems, like smart city projects, the different roles they play in such projects when dealing with KM governance and processes issues are still understudied. Therefore, by conducting an exploratory case study of 20 smart city projects, this paper aims to scrutinize how universities manage the KM governance issue when internal knowledge is used, the KM governance issue when external knowledge is used, the KM processes issue when internal knowledge is used, and the KM processes issue when external knowledge is used. Results reveal that universities act as knowledge intermediaries, knowledge gatekeepers, knowledge providers, and knowledge evaluators. © 2018 Elsevier Inc
