    Semiparametric Spatial Autoregressive Model: A Two-Step Bayesian Approach
    Authors: Jiaqing Chen, Renfu Wang and Yangxin Huang
    Abstract: Spatial data arise frequently in econometric studies and it is a common practice to analyze such data with spatial autoregressive (SAR) models. This paper proposes a two-step Bayesian approach for inference in the semiparametric spatial autoregressive (SPSAR) model, including the cases for mixed data.

    We always had the concept of perfect images-society has always influenced the way people should look, so body dissactisfation due to social beauty standards has always been around. These perfect images seem to have a deep impact in the adolescents relationship with their body thus leading to maladaptive behaviors: restrictive dieting, excessive exercise and vomiting. Since the main source of these rule models resides in social media it was mandatory to further explore the part of social media in body dissatisfaction and eating disorders among teenagers.
    By reviewing 12 different papers about body dissatisfaction, social media and eating disorders we attempted to further explore this complicated relationship and to reunite information that indeed corroborates the theory that social media has a deep impact in increasing numbers of eating disorders among adolescents.
    After our search review we concluded that there is a positive association between social media, body dissatisfaction in teenagers and eating disorders. Plus, this phenomenon is being increasing in numbers for a few years and it peeked after COVID-19 and the lockdown.

    Objective: Dentists use social media (SM) for various reasons, but only limited studies explored their use for dental marketing. This study aimed to explore the use of social media among dentists in Jordan to market their dental practice.
    Materials and Methods: This cross-sectional study used a self-administrated online questionnaire of 17 items distributed to 1000 dentists. The survey included questions related to dentists demographic and profession-related information, SM use in general, and social media use for dental practice marketing. Chi-square test was conducted to assess the association of dentists demographic and professional information with SM use for marketing.
    Results: There were a total of 510 dentists participating in the study. Approximately two thirds (68.4%) were working in the private sector. Facebook was the most popular SM platform used by dentists (97.6%) and the primary purpose of using SM accounts was for personal uses. Yet, about one third (31.2%) of dentists were using SM for marketing, and three-quarters of dentists were thinking that using SM for marketing is effective and practical (73.3%). Dental marketing through SM was significantly higher among males, those younger than 40 years old, private sector practitioners, and dentists who obtained training in cosmetic dentistry or professional training on SM use.
    Conclusion: Dentists hold a positive attitude toward SM as an effective tool for gaining new patients. Yet, a small percentage of dentists were using SM to market their practice. Training in cosmetic dentistry or professional training on SM use could contribute to dental marketing through SM in the future.

    Background: Sars-CoV-2 is a coronavirus associated with human severe acute respiratory disease named Covid-19, first reported in China on December 2019. World Health Organization declared Covid-19 a pandemic on March 20, 2020. This report aims to outline the Italian outbreak characteristics. Italy, as one of first most affected area outside Asian continent, could give experiences to the other countries.
    Methods: Data on positive cases and Covid-19 patients made available by Italian Health Authorities were reanalyzed and described.
    Results: Up to April 18, 2020 Italy recorded 175,925 Sars-CoV-2 positive cases (10.68% among health care professionals) and 23,227 Covid-19 deaths. Covid-19 patients median age was 62 years. Male/female ratio was 1.00. Median time between symptoms and diagnosis was 6 days. Between hospitalized patients, the 10% needed intensive care. Median age at death was 80 years, with differences between sexes. Apparent lethality rate was 13.2%. At least one concomitant medical condition was present in 96.4% of patients who died.
    Discussion: The number of Italian positive cases could be higher and the Italian lethality rate could be lower. The presence of asymptomatic people, known to be a vehicle for Covid-19 also for serious cases, could made slower the decrease of infection and distance the end of the novel coronavirus epidemic.
