We develop a three dimensional compartmental model to investigate the impact of media coverage to the spread and control of infectious diseases (such as SARS) in a given region/area. Stability ...analysis of the model shows that the disease-free equilibrium is globally-asymptotically stable if a certain threshold quantity, the basic reproduction number (
), is less than unity. On the other hand, if
, it is shown that a unique endemic equilibrium appears and a Hopf bifurcation can occur which causes oscillatory phenomena. The model may have up to three positive equilibria. Numerical simulations suggest that when
and the media impact is stronger enough, the model exhibits multiple positive equilibria which poses challenge to the prediction and control of the outbreaks of infectious diseases.

The incorporation of Internet resources and the use of social media among patients, clinicians, advocates, and researchers in the field of hematology and oncology are growing in importance. ...Utilization of online information sharing is rising, especially among those involved in rare blood cancer fields, which have generally featured a paucity of reliable, updated information. In particular, blastic plasmacytoid dendritic cell neoplasm (BPDCN), an uncommon, but highly aggressive hematologic malignancy, is one example of a cancer with limited information readily available to the general public. The infrequent incidence of BPDCN, the challenges in recognizing the disease and making a clinico-pathologic diagnosis, and the lack of standard therapies are some of the reasons accounting for the dearth of expert opinion, scientific publications and discussion, and accessibility of online information for patients. This article highlights social media and Internet sources available for patients and other healthcare stakeholders in the field of BPDCN and discusses our efforts to increase awareness and propagation of BPDCN electronic resources, including the founding of an online Twitter community, #BPDCN.

Las citas periodísticas de revistas, autores y artículos científicos se han utilizado avant la letre para estudiar el impacto de la ciencia en la prensa generalista y algunas características del ...periodismo científico. En este artículo se revisa el estado de la cuestión y se perfilan los conceptos de cita periodística e impacto mediático por analogía con los de cita científica e impacto científico, estableciendo sus similitudes y diferencias. Se analizan las posibilidades de investigación que ofrece el recuento de citas periodísticas y el desarrollo de indicadores del impacto mediático de la ciencia. El análisis de citas periodísticas presenta ventajas frente a las métricas alternativas o altmétricas, pues la prensa es el principal productor de noticias y ofrece un producto más consolidado y con un filtro profesional. También presenta limitaciones, principalmente por la falta de una base de datos de citas periodísticas de las revistas científicas en la prensa generalista internacional.

We proposed a delay differential model, associated with the response time for individuals to the current infection, to examine the media impact on the transmission dynamics of infectious diseases. We ...investigated the global bifurcation by considering the delay as a bifurcation parameter and examined the onset and termination of Hopf bifurcations from a positive equilibrium. Numerical studies to identify ranges of parameters for coexisting multiple periodic solutions are guided by the bifurcation analysis and the Matlab package DDE-BIFTOOL developed by Engelborghs et al. Further, we parameterized the proposed model on the basis of the 2009 A/H1N1 pandemic influenza data in Shaanxi province, China, and estimated the basic reproduction number to be 1.79 95% CI (1.77–1.80) and the time delay to be 2.94 days 95% CI (2.56–3.24). Our main results indicated that media impact with time delay significantly influenced the transmission dynamics of infectious diseases.

Understanding the factors that influence adolescent's perception of fast food and their fluid consumption is crucial for designing effective nutrition education programs tailored to this population. ...This study aimed to evaluate the associations of sex and the use of media and the internet with adolescents' perception of fast foods and the amount of fluid consumption.
A cross-sectional survey was conducted on school adolescents between the ages of 15 and 18 years in Kuwait, using a multistage stratified random sampling method (N = 706 adolescents; 343 boys and 363 girls). A pre-tested and specifically designed self-report questionnaire covering several measures such as: (a) types of foods that are considered fast foods; and (b) participant's fluid consumption. Body weight and height were measured using calibrated medical scales. Body mass index (BMI) was computed. The adolescents were stratified by sex into two groups: boys and girls, for the purpose of analysis.
Seven out of 14 food choices showed significant sex differences (p values ranged from 0.016 to < 0.001) in the adolescents' responses to whether they perceived such food choice as fast food or not. Although differences were found between sexes, the majority of the listed fast foods were correctly recognized as fast foods by the adolescents. In addition, there were significant differences between males and females in the amount of daily drinks (ml/week) consumed from full fat milk (males = l197.1 ± 27,652.1 and females = 1662.8 ± 2221, p = 0.013), sugar-sweetened beverage (males = 2350.8 ± 3324.3 and females = 3088.9 ± 3701.1, p = 0.004), and energy drinks (males = 429.5 ± 1117.2 and females = 267.6 ± 733.8, p = 0.037). Compared to adolescents who seldom or do not watch TV or use the internet, those who engage in these sedentary activities are less likely to classify pizza (aOR (95% CI) = 0.660 (0.440-0.990), p = 0.045), grilled meat (aOR (95% CI) = 0.674 (0.477-0.954), p = 0.026), fried egg sandwiches (aOR (95% CI) = 0.617 (0.425-0.894-0.189), p = 0.011), and rice (aOR (95% CI) = 0.598(0.409-0.875), p = 0.008) as fast foods.
The influence of TV and internet use on adolescent's ability to accurately identify fast foods has been observed. Findings indicate the need for increased fast food nutrition education programs that are tailored towards adolescents. The study recommends further research to enhance consumer awareness of foods and drinks among adolescents in the State of Kuwait.

Research Questions/Issues
Do media pressure and firm reputational concerns propel corporate governance improvements? Specifically, can they encourage unifications of dual ...class shares into a single “one share one vote” class?
Research Findings/Insights
Media criticism increases the likelihood of voluntary dual class share unifications. Firms more sensitive to public image are more likely to unify their dual class shares.
Theoretical/Academic Implications
Media plays an important role in corporate governance promotion. Firm reputation is a valuable asset, sensitive to public opinion and media criticism. Some real firm decisions can be influenced by firm image and reputation considerations.
Practitioner/Policy Implications
Firm image, reputation, and public relations activity are valuable. Media is a powerful and flexible tool that in some cases can substitute regulation in effectively restraining firms and their controlling shareholders.

, while the endemic equilibrium may become unstable and Hopf bifurcation occurs for some appropriate conditions by taking the level of media impact as bifurcation parameter. With two time delays, we comprehensively investigated the local and global bifurcation by considering the summation of delays as a bifurcation parameter, and theoretically and numerically examined the onset and termination of Hopf bifurcations from the endemic equilibrium. Main results show that either the media described feedback cycle, from infection to the level of mass media and back to disease incidence, or time delays can induce Hopf bifurcation and result in periodic oscillations. The findings indicate that the delayed media impact leads to a richer dynamics that may significantly affect the disease infections.

This research aims to analyze how the media can favor economic development at the regional level, observing how mass media reports on the economy are relevant to Romania's population, and if the ...content provided stimulates economic development action. Mass media is one of the main channels of information for many companies, and the acquisition of correct and qualitative information generates informed decisions. Additionally, the mass media has the role of producing changes in the behavior of the consuming public, and in its culture, and can improve its educational level. Although the variety of information sources, which has been improved over time by technology, does not guarantee their use, the mass media, through the information it provides, can change attitudes and values, and lead to a higher standard of living. The present study includes both qualitative and quantitative methods, which look at the media and its effects on companies. Through two surveys, data were collected on how the population relates to the information obtained from the mass media, as well as how the mass media is used by the companies in the Northeast Region of Romania. The benefits and challenges that companies encounter while using social networks have thus been determined. Additionally, the qualitative method was used, in order to be able to observe whether there are significant differences in the use of social networks to develop an emerging business, in terms of the male-female ratio.
To explore the effects of propaganda and education on the prevention and control of AIDS infection, a model of AIDS transmission in MSM population is proposed and theoretically analyzed by ...introducing media impact factors. The basic reproduction number of AIDS transmission in MSM group without media intervention R
= 1.5447 is obtained. Based on the comparison of the implementation of three different detection and treatment measures, it can be concluded that the promotion of condom use is more effective than other strategies, and using condoms with a fixed partner can reduce the value of R
more quickly.
