    Full Text Available The media establish, in large part, the patterns of visibility and public recognition of collective identities. We define media identities as those that are the object of production and diffusion by the media. From this discourse, the communities and individuals elaborate media-influenced identifications; that is, processes of recognition or banishment; (rearticulating the identity markers that the media offer with other cognitive and emotional sources. The generation and appropriation of the identities are subjected to a media hierarchisation that influences their normalisation or marginalisation. The identities presented by the media and assumed by the audience as part of the official, hegemonic discourse are normalised, whereas the identities and identifications formulated in popular and minority terms are marginalised. After presenting this conceptual and analytical framework, this study attempts to outline the logics that condition the presentation, on the one hand, andthe public recognition, on the other hand, of contemporary identities.

    Angiotensin II (AngII) acts on central neurons to increase neuronal firing and induce sympathoexcitation, which contribute to the pathogenesis of cardiovascular diseases including hypertension and heart failure. Numerous studies have examined the precise AngII-induced intraneuronal signaling mechanism in an attempt to identify new therapeutic targets for these diseases. Considering the technical challenges in studying specific intraneuronal signaling pathways in vivo, especially in the cardiovascular control brain regions, most studies have relied on neuronal cell culture models. However, there are numerous limitations in using cell culture models to study AngII intraneuronal signaling, including the lack of evidence indicating the stability of AngII in culture media. Herein, we tested the hypothesis that exogenous AngII is rapidly metabolized in neuronal cell culture media. Using liquid chromatography-tandem mass spectrometry, we measured levels of AngII and its metabolites, Ang III, Ang IV, and Ang-1-7, in neuronal cell culture media after administration of exogenous AngII (100 nmol/L) to a neuronal cell culture model (CATH.a neurons). AngII levels rapidly declined in the media, returning to near baseline levels within 3 h of administration. Additionally, levels of Ang III and Ang-1-7 acutely increased, while levels of Ang IV remained unchanged. Replenishing the media with exogenous AngII every 3 h for 24 h resulted in a consistent and significant increase in AngII levels for the duration of the treatment period. These data indicate that AngII is rapidly metabolized in neuronal cell culture media, and replenishing the media at least every 3 h is needed to sustain chronically elevated levels. © 2015 The Authors.

    The basic concept of effective stress describes the characteristics of fluid and solid interaction in porous media. In this paper, based on the theory of fractal geometry, a fractal model was built to analyze the relationship between the microstructure and the effective stress of porous media. From the microscopic point of view, the influence of effective stress on pore structure of porous media was demonstrated. Theoretical analysis and experimental results show that: (i) the fractal model of effective stress can be used to describe the relationship between effective stress and the microstructure of porous media; (ii) a linear increase in the effective stress leads to exponential increases in fractal dimension, porosity and pore number of the porous media, and causes a decreasing trend in the average pore radius.

    The portrayal of violence, sex, and drugs/alcohol in the media has been known to adversely affect the behavior of children and adolescents. There is a strong association between perceptions of media messages and observed behavior, especially with children. Lately, there has been more of a focus in the public health/medical field on media influences of youth and the role of the pediatrician and/or healthcare worker in addressing this area of growing concern. There is a need to explicitly explore the influences of media violence, sex, and drugs/alcohol on youth within the context of the Social Learning Theory. Implications of these influences are discussed, and recommendations for pediatricians and/or health care workers who interact with children and adolescents are described. Pediatricians and health care workers should incorporate media exposure probes into the developmental history of their patients and become knowledgeable about the effects of medial influences on youth.

    How far do Media (Television, Video Games, Publications) influence the behavior of young people? The increasing occurrence of violent behavior (e.g. amuck shootings) suggest a negative influence upon the minds and behavior of youth. Psychologists point to the effects of propaganda, the fallacy of "behaviorism" and the facts of experience with addiction (e.g. pornography) and physical effects on the brain.

  14. Boomers versus Millennials: Online Media Influence on Media Performance and Candidate Evaluations

    Full Text Available Facebook posts, YouTube videos, tweets and wooing political bloggers have become standard practice in marketing political campaigns. Research has demonstrated the effect of new media on a host of politically-related behavior, including political participation, knowledge acquisition, group formation and self-efficacy. Yet, issues related to media trust, media performance and candidate evaluations have not been fully explored. In addition, much of the political marketing research looks exclusively at the Millennial age cohort, ignoring other age groups, particularly Baby Boomers. This case study addresses whether attention to traditional (i.e., television, hard-copy newspapers and radio and online media sources (i.e., political candidate websites, television network websites, online newspapers, Facebook, Twitter, YouTube, Tumblr and political blogs about the 2012 U.S. presidential campaign influences Millennials and Baby Boomers’ media trust and performance ratings, as well as candidate evaluations. Panel surveys were completed by both age cohorts, Millennials (n = 431 and Baby Boomers (n = 360, during the last two weeks of the presidential election. Findings indicate that traditional sources, specifically television, rather than online sources are significantly linked to media trust and performance ratings among both Boomers and Millennials. Attention to traditional media for campaign information predicts Boomers’ candidate evaluations, whereas Millennials’ candidate evaluations are influenced by online sources, such as Facebook and candidate websites.

    Media influences behaviour, especially of the young children and adolescents in various ways. The present study examined the media coverage of a judicial hanging and its immediate social effect. In a qualitative study the media coverage of a case of a judicial hanging was thoroughly discussed and the media influence, for over a period of ten weeks of the incident, in terms of suicide and copying of hanging among children, was collected and analysed. Eighteen cases were reported as an aftermath of this hanging: 1 suicide and 17 imitative hanging in children with 5 deaths. This report calls for attention that media should be cautious and responsible in presenting the news items that have potential social impact.

    The media is a powerful societal tool for expressing expectations about how men and women should look. As a result, over the past several years, women have shown an increase in body dissatisfaction (Cash, Morrow, Hrabosky, & Perry, 2004). The present study examined the relationships between drive for thinness, self-esteem, and media influence among men and women. Two hundred ninety-four college students completed the Texas Social Behavior Inventory (Helmreich & Stapp, 1974), Sociocultural Attitudes towards Appearance Scale-3 (Thompson, van den Berg, Roehrig, Guarda, & Hienberg, 2004), self-constructed questionnaire influence of media models, and the drive for Thinness Subscale (DT) from the Eating Disorder Inventory-3 (EDI-3; (Garner, 2004)). We expected to find an association between drive for thinness and media influence and between drive for thinness and self-esteem for both men and women. Finally, we expected that the use of media, social pressures and media internalization would be predictors of drive for thinness. We found a relationship between media influence and drive for thinness. There was also a relationship between self-esteem and drive for thinness. For both men and women, media models were the primary predictor for drive for thinness. However, for women the secondary predictor was social pressures; whereas for men the secondary predictor was internalization. Such findings show the importance of examining the impact of media sources on men and women in order to entangle gender differences. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available The theme of this study is a distinct examination of the issues regarding health policy, social representations and mass media. The analysis of the mass media influence on the impact of health policy leads to a portrayal of the related programs and the way they are received by citizens through mass media. Owing to the mass media quality to be an indicator of democracy it is very important to study its role in setting people daily agenda considering how it is able to maintain and create trends merely through recurrent messages. The issues frequently conveyed by media industry influences citizens’ interest with regard to community, producing effects on public policy. We must bear in mind that the more persistent in media they are, the more relevant for community this issues will be. The authors of the study put forward a method through which diverse programmes can be analysed. A comparative analysis of mass media and citizens’ social representations and its findings provide information about the influence between them. According to agenda setting theory and many international studies on health policy the authors conclude that mass media institution highly influence the impact of the health policy in health. Moreover, it is important to mention that the impact refers to all the stages of a policy-making: beginning with the problem identification and ending with the evaluation of the implementation process.

    The current study examined whether media internalization, found to mediate the relationship between selected prevention programs and outcomes, mediated the impact of two universal prevention programs that targeted risk factors for eating disorders and obesity, namely weight concern, and shape concern. Students randomized to a media literacy (Media Smart) program (N = 269, 65% females, mean age 12.97 years) and a healthy lifestyle (Life Smart) program (N = 347, 69% females, mean age 13.07 years) were included in the analyses. There were four waves of data (baseline, end of intervention, 6- and 12-month follow-up). Latent growth curve modeling was used to explore whether group assignment influenced levels of media internalization, and whether that in turn influenced change over time of our two outcome variables. Being randomly allocated to Media Smart as opposed to Life Smart resulted in less growth of both outcome variables through the influence on decreasing levels of media internalization. Findings provided support for the suggestion that media literacy programs exert an impact on outcomes related to eating disorder risk through changes to media internalization. Future research should examine whether these mechanisms of change differ between girls and boys. © 2017 Wiley Periodicals, Inc.

    Based on the influence of presumed media influence (IPMI) model as the theoretical framework, this study examines how injunctive norms and personal norms mediate the influence of healthy lifestyle media messages on public intentions to engage in two types of healthy lifestyle behaviors-physical activity and healthy diet. Nationally representative data collected from 1,055 adults in Singapore demonstrate partial support for the key hypotheses that make up the extended IPMI model, highlighting the importance of a norms-based approach in health communication. Our results indicate that perceived media influence on others indirectly shaped public intentions to engage in healthy lifestyle behaviors through personal norms and attitude, providing partial theoretical support for the extended IPMI model. Practical implications for health communicators in designing health campaigns media messages to motivate the public to engage in healthy lifestyle are discussed.

    Anti-tobacco mass media campaigns are designed to influence tobacco users. It has been proved that campaigns will produce users' changes in awareness, knowledge, and attitudes, and also produce meaningful behavior change of audience. Anti-smoking television advertising is the most important part in the campaign. Meanwhile, nowadays, successful online social networks are creating new media environment, however, little is known about the relation between social conversations and anti-tobacco campaigns. This paper aims to infer social influence of these campaigns, and the problem is formally referred to as the Social Influence inference of anti-Tobacco mass mEdia campaigns (Site) problem. To address the Site problem, a novel influence inference framework, TV advertising social influence estimation (Asie), is proposed based on our analysis of two real anti-tobacco campaigns. Asie divides audience attitudes toward TV ads into three distinct stages: 1) cognitive; 2) affective; and 3) conative. Audience online reactions at each of these three stages are depicted by Asie with specific probabilistic models based on the synergistic influences from both online social friends and offline TV ads. Extensive experiments demonstrate the effectiveness of Asie.

    2017-07-01

    This study examined the role of media influence and immigration on body image among Pakistani men. Attitudes toward the body were compared between those living in Pakistan ( n = 56) and those who had immigrated to the United Arab Emirates ( n = 58). Results of a factorial analysis of variance demonstrated a significant main effect of immigrant status. Pakistani men living in the United Arab Emirates displayed poorer body image than those in the Pakistan sample. Results also indicated a second main effect of media influence.Those highly influenced by the media displayed poorer body image. No interaction effect was observed between immigrant status and media influence on body image. These findings suggest that media influence and immigration are among important risk factors for the development of negative body image among non-Western men. Interventions designed to address the negative effects of the media and immigration may be effective at reducing body image disorders and other related health problems in this population.

    2017-10-01

    The Influence of Media Consumption During Early Childhood on Media Use and Psychological Disorders in Adolescence There are many studies that suggest that there is a link between high media consumption and psychological, physiological and social disorders. Nevertheless, there are also inconsistent results, methodical limitations and a lack of longitudinal studies. The present study analyses habits of media consumption in children and adolescents, the influence of different early childhood risk factors on the use of the media in adolescence and the links between early childhood media consumption and disorders in adolescence. The source of the data is the longitudinal project Future Family III. 249 families participated in the last data collection in the adolescence. Adolescents use the media more than five hours per day on average, nearly fifty percent of these adolescents can be considered as internet addicted and a majority consumes violent contents. A low socioeconomic status, low socio-emotional competences and low intelligence of the child as well as unfavorable educational style and psychological stress of the mother are risk factors for the media use in adolescence. Adolescents with a migration background have an increased risk of internet and computer game dependency. On the other hand, the overall utilization of media in the early childhood has only a low predictive power. The results indicate that these connections seem to be more complex than assumed. There is a need for more longitudinal studies in order to get a better understanding of the consequences of media consumption.

    2003-05-01

    This paper summarizes results of empirical studies on cigarette advertising and promotions, antismoking advertising, product placement in movies, on television and in music media and news coverage about smoking. In addition, we provide an overview of some of the theoretical literature relevant to the study of media uses and effects. Finally, we discuss empirical findings in the context of these theories to draw some conclusions about media influences on smoking and identify issues for further research. We conclude that (a) the media both shape and reflect social values about smoking; (b) the media provide new information about smoking directly to audiences; (c) the media act as a source of observational learning by providing models which teenagers may seek to emulate; (d) exposure to media messages about smoking also provides direct reinforcement for smoking or not smoking; (e) the media promote interpersonal discussion about smoking; (f) the media can influence "intervening" behaviors that may make teenage smoking less likely; and (g) antismoking media messages can also set the agenda for other change at the community, state or national level. We outline priorities for further research which emphasize the need for longitudinal studies, multi-level studies, an awareness of the probably dynamic relationship between tobacco advertising and antismoking advertising, the importance of determining appraisal of tobacco industry youth smoking prevention efforts and the dearth of research on news coverage about smoking.

    One central aspect of health literacy is knowledge of patients' rights. Being an important source of information about health and health care, the media may influence health literacy and act as a policy implementer. To investigate whether regional news media coverage in Sweden is linked to (i) the public's awareness and knowledge of a patient's rights policy, the waiting-time guarantee and (ii) the public's attitudes to how the guarantee's time limits are met, that is, implementation success. Three types of data are used. First, a national telephone survey of the public's awareness, knowledge and attitudes; second, media coverage information from digital media monitoring; and third, official waiting-time statistics. Bivariate and multivariate regression analyses are performed with the 21 Swedish county councils/regions as a base. In the county councils/regions, non-awareness ranged from 1 to 15% and knowledge from 47 to 67%. There are relatively large differences between population groups. The amount of regional media coverage shows no significant correlation to the level of awareness and knowledge. There is, however, a significant correlation to both positive and negative attitudes; the latter remains after controlling for actual waiting times. At the national level, the media function as a policy implementer, being the primary source of information. At the regional level, the media are part of the political communication, reporting more extensively in county councils/regions where the population holds negative views towards the achievement in implementing the guarantee. We conclude that Swedish authorities should develop its communication strategies to bridge health literacy inequalities. © 2014 John Wiley & Sons Ltd.

    about social behavior, and by reducing individuals' normal negative emotional responses to violence (i.e., desensitization). Certain characteristics of viewers (e.g., identification with aggressive characters), social environments (e.g., parental influences), and media content (e.g., attractiveness of the perpetrator) can influence the degree to which media violence affects aggression, but there are some inconsistencies in research results. This research also suggests some avenues for preventive intervention (e.g., parental supervision, interpretation, and control of children's media use). However, extant research on moderators suggests that no one is wholly immune to the effects of media violence. Recent surveys reveal an extensive presence of violence in modern media. Furthermore, many children and youth spend an inordinate amount of time consuming violent media. Although it is clear that reducing exposure to media violence will reduce aggression and violence, it is less clear what sorts of interventions will produce a reduction in exposure. The sparse research literature suggests that counterattitudinal and parental-mediation interventions are likely to yield beneficial effects, but that media literacy interventions by themselves are unsuccessful. Though the scientific debate over whether media violence increases aggression and violence is essentially over, several critical tasks remain. Additional laboratory and field studies are needed for a better understanding of underlying psychological processes, which eventually should lead to more effective interventions. Large-scale longitudinal studies would help specify the magnitude of media-violence effects on the most severe types of violence. Meeting the larger societal challenge of providing children and youth with a much healthier media diet may prove to be more difficult and costly, especially if the scientific, news, public policy, and entertainment communities fail to educate the general public about the real

    2014-01-01

    Participation in online social media Web sites (e.g., Facebook and Twitter) has skyrocketed in recent years and created a new environment in which adolescents and young adults may be exposed to and influenced by alcohol-related content. Thus, young people are exposed to and display pro-alcohol messages and images through online portrayals of drinking on personal pages as well as unregulated alcohol marketing on social media sites that may reach underage people. Such online displays of alcohol behavior have been correlated with offline alcohol behavior and risky drinking. Health behavior theories have been used to describe the influence of social media sites, including Social Learning Theory, the Media Practice Model, and a more recent conceptual approach called the Facebook Influence Model. Researchers are beginning to assess the potential of social media sites in identifying high-risk drinkers through online display patterns as well as delivering prevention messages and interventions. Future studies need to further expand existing observational work to better understand the role of social media in shaping alcohol-related behaviors and fully exploit the potential of these media for alcohol-related interventions.

    2016-08-01

    Social media has been used as an important tool by firms to influence consumers’ attitude and behavior. Influence occurs in consumer communities in social media because community members have the control of discovering, producing, sharing, and distributing information and because the spread out of their experiences and opinions in the format of electronic word-of-mouth forms emerging conformance. Prior research has explored how the influence occurring in online social media communities impacts consumers’ attitude and behavior (e.g., product attitude and purchase decision, effectual thinking and behavior, brand trust and brand loyalty). But because social media has the ability of global reach, cross-border factors should not be neglected in studying the influence process. As such, this paper adopts national cultural dimensions identified by Hofstede (1984), individualism/collectivism and power distance particularly, the index of cultural distance, and the social influence theory to explore how culture impacts the influence occurring in consumer communities in social media.

    2010-12-01

    Racial differences in the effects of peer and media influence on adolescents' alcohol cognitions and consumption were examined in a large-scale panel study. With regard to peer influence, results from cross-lagged panel analyses indicated that the relation between perceived peer drinking and own drinking was significant for both Black and White adolescents, but it was stronger for the White adolescents. With regard to media influence, structural modeling analyses indicated that exposure to drinking in movies was associated with more alcohol consumption 8 months and 16 months later. These effects were mediated by increases in the favorability of the adolescents' drinker prototypes, their willingness to drink, and their tendency to affiliate with friends who were drinking. Multiple group analyses indicated that, once again, the effects (both direct and indirect) were much stronger for White adolescents than for Black adolescents. The results suggest media influence works in a similar manner to social influence and that Whites may be more susceptible to both types of influence.

    Raman spectroscopy has a broad range of applications across numerous scientific fields, including microbiology. Our work here monitors the influence of culture media on the Raman spectra of clinically important microorganisms (Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis and Candida albicans). Choosing an adequate medium may enhance the reproducibility of the method as well as simplifying the data processing and the evaluation. We tested four different media per organism depending on the nutritional requirements and clinical usage directly on a Petri dish. Some of the media have a significant influence on the microbial fingerprint (Roosvelt-Park Institute Medium, CHROMagar) and should not be used for the acquisition of Raman spectra. It was found that the most suitable medium for microbiological experiments regarding these organisms was Mueller-Hinton agar.

    Highly sensitive and interference-free sensitized spectrophotometric method for the determination of Ni(II) ions is described. The method is based on the reaction between Ni(II) ion and benzyl dioxime in micellar media in the presence of sodium dodecyl sulfate (SDS). The absorbance is linear from 0.1 up to 25.0 μg mL -1 in aqueous solution with repeatability (RSD) of 1.0% at a concentration of 1 μg mL -1 and a detection limit of 0.12 ng mL -1 and molar absorption coefficient of 68,600 L mol -1 cm -1. The influence of reaction variables including type and amount of surfactant, pH, and amount of ligand and complexation time and the effect of interfering ions are investigated. The proposed procedure was applied to the determination of trace amounts of Ni(II) ion in tap water, river water, chocolate and vegetable without separation or organic solvent extraction.

    Recent studies demonstrate that board-certified plastic surgeons are underrepresented amongst individuals posting public-directed marketing plastic surgery-related content on Instagram. However, peer-to-peer and education-based social media influence has not been studied. Twitter is a social media platform has been suggested to be useful for educating the masses and connecting with colleagues. The purpose of this study is to identify the top influencers in plastic surgery on Twitter, characterize who they are, and relate their social media influence to academic influence. Twitter influence scores for the topic search "plastic surgery" were collected in July 2017 using Right Relevance software. The accounts associated with the highest influencer scores were linked to individual names, status as a plastic surgeon, board certification, location, and academic h-index. The top 100 Twitter influencers in plastic surgery are presented. Seventy-seven percent of the top influencers are trained as plastic surgeons or facial plastic surgeons. Sixty-one percent of influencers are board-certified plastic surgeons or board-eligible/future eligible trainees. International plastic surgeons made up 16% of influencers. Other medical doctors made up another 10%. The other 13% of influencers were nonphysicians. Three-quarters of social media influencers were physically located in the United States. Academic h-index of social media influencers ranged from 0 to 62 (mean, 8.6). This study shows that the top plastic surgery social media influencers on Twitter are predominantly board-certified or eligible plastic surgeons and physically based in the United States. This study also provides the influencer network for other plastic surgeons to engage with to improve their own influence within the plastic surgery social media sphere.

One of the instruments of promotion is economic propaganda (advertising, which uses a number of media such as television, radio, newspapers, billboards, Internet and others. By using various media, the company affects the consumer awareness of the brand, spreads information about themselves and the brand, educates consumers, creates a brand image and the like. The aim of this study is to investigate the influence of different media of advertising on consumer awareness of the brand, as well as to investigate that influence in the context of socio-demographic characteristics of respondents. The methods used in the work are historical and research (field and online methods and include a total of 690 respondents from Serbia in the period February-April 2017. For data analysis, we used the independent-samples t-test and the Spearman’s rank correlation coefficient. The results showed that television has the strongest impact on brand awareness. The Internet and billboards follow, while the weakest effect is that of newspapers and radio. Results show that in the context of gender, age, education and income of respondents, there are reasons to analyze the impact of television, radio, newspapers, billboards and the Internet to consumer awareness of the brand in a different manner. The contribution of the thesis is also reflected in the fact that, on the basis of the obtained results, the authors give recommendations, when it comes to perception and brand awareness, on the media that are an adequate promotional instrument for a particular segment of consumers.

    Building on the influence of presumed influence (IPI) model, this study examines how smoking- related messages on social media influence college students' smoking. We surveyed 366 college students from three U.S. Midwestern universities in 2012 and examined the effects of expression and reception of smoking-related messages on smoking using path analysis. We found that the expression and reception of prosmoking messages not only directly affected smoking but also had indirect effects on smoking through (1) perceived peer expression of prosmoking messages and (2) perceived peer smoking norms. For antismoking messages, only reception had a significant indirect influence on smoking through (1) perceived peer reception of antismoking messages and (2) perceived peer smoking norms. In conclusion, social media function as an effective communication channel for generating, sharing, receiving, and commenting on smoking-related content and are thus influential on college students' smoking.

    2014-10-23

    Tobacco use among young Pacific populations continues to undermine efforts to reduce the escalating rates of non-communicable disease in the region. Reducing tobacco use to less than 5 percent by 2025 is now a World Health Organisation (WHO) mandated target for the Pacific region. Yet, little is known about the drivers to uptake of tobacco use among young people in the Pacific. Family and peers are expected to be important in this process, but similarly, tobacco marketing may also play an important role. The tobacco industry has been highly adaptive to the changing media environment across the Pacific Islands. The aim of this study was to develop an understanding of the social cultural and media drivers to tobacco uptake and use among young Samoans to contribute to the design of effective tobacco control intervention. We examined high school students (aged 16 and 17 years) perceptions of tobacco use in their community, access and use of media channels and the extent to which they are cognizant of both pro and anti-tobacco imagery across a range of media. Data was collected through in-depth semi-structured interviews. A thematic analysis of the interview data identified common and divergent beliefs, attitudes and behaviours surrounding tobacco use and the influence of the media. Family is critically important for representing normative tobacco use in Samoa. The use of media, in particular digital media, was found to be conditioned by parental views on the use of media in the home. Media access remains highly regulated within more traditional households. Loyalty to traditional cultural practices (Fa'a Samoa) underpinned views on the limited influence of media on social norms around tobacco use. Parents were thought to have the greatest influence on youth smoking. Tobacco use was viewed as a personal, or family issue, and not a problem that was amendable to change at a societal level. In order to develop effective and culturally relevant tobacco control policies, the

    The current study explored the relation between sexual orientation, media persuasion, and eating and body image concerns among 78 college men (39 gay; 39 straight). Participants completed measures of sexual orientation, eating disorder symptoms, appearance-related anxiety, perceived importance of physical attractiveness, perceptions of media influence, and media exposure. Gay men scored significantly higher on drive for thinness, body dissatisfaction, and body image-related anxiety than their straight counterparts. Additionally, perceptions of media influence were higher for gay men, and significantly mediated the relation between sexual orientation and eating and body image concerns. Sexual orientation also moderated the relation between perceived media influence and beliefs regarding the importance of physical attractiveness, as this relation was significant for gay men, but not straight men. The current findings suggest that gay men's increased vulnerability to media influence partially accounts for the relatively high rate of eating pathology observed in this population.

    2016-06-01

    In this study, we evaluated associations of experiences with mass media imported from Western nations such as the United States versus mass media from China and other Asian countries with eating and body image disturbances of young Chinese women. Participating women (N=456) completed self-report measures of disordered eating, specific sources of appearance dissatisfaction (fatness, facial features, stature), and Western versus Chinese/Asian mass media influences. The sample was significantly more likely to report perceived pressure from, comparisons with, and preferences for physical appearance depictions in Chinese/Asian mass media than Western media. Chinese/Asian media influences also combined for more unique variance in prediction models for all disturbances except stature concerns. While experiences with Western media were related to disturbances as well, the overall impact of Chinese/Asian media influences was more prominent. Copyright © 2016 Elsevier Ltd.

    Roberson, Angela A; McKinney, Cliff; Walker, Courtney; Coleman, Ashley

    2018-07-01

    To investigate how alcohol marketing and peers may promote college students' alcohol use through social media. College students (N = 682) aged 18 to 22 years from a large Southern university completed paper surveys in April 2014. Structural equation modeling was used to investigate relationships among variables as well as moderation by gender and race. Drinking behavior was directly related to perceived norms and attitudes toward alcohol that develop, in part, from direct and indirect interactions with their online and offline peers, as well as engagement with alcohol-related content on social media. Gender and ethnicity moderated some effects. College student drinking is influenced by friends' alcohol-related content posted on social networking sites and by greater engagement with traditional and online alcohol marketing. College campus alcohol misuse interventions should include components to counter peer influences and alcohol marketing on social media.

    To investigate the impact of media reporting of a celebrity suicide on subsequent suicide attempts. A Poisson time series autoregression analysis was conducted to examine whether there was a significant increase in suicide attempts during the 3-week period after the start of extensive media reporting of a celebrity suicide. The reporting began on May 2, 2005, and lasted about 17 days. To investigate the influence of media reporting on suicide attempts, a structured interview was conducted with 124 suicide attempters identified from 2 counties in Mid Taiwan who had exposure to the media reporting. After controlling for seasonal variation, calendar year, temperature, and humidity, there was a marked increase in the number of suicide attempts during the 3-week period after media reporting began (adjusted relative risk = 1.55, 95% CI = 1.26 to 1.91). Among 124 suicide attempters exposed to the media reports, 23.4% reported an influence from them. There was no relationship between the attempters' ages and the age of the celebrity or the method, but male attempters had a significantly higher risk for such influence. A considerably higher risk for such influence was found among subjects with a history of suicide attempt(s) in the previous year (odds ratio = 52.3, 95% CI = 5.96 to 459.1). The extensive media reporting of the suicide of a celebrity was followed by an increase in suicide attempts. The effect was particularly marked in individuals with a recent history of a suicide attempt. The results provide further support for the need for more restrained reporting of suicides as part of suicide prevention strategies and for special vigilance for contagious effects of such reporting on people who have carried out recent suicidal acts.

    2010-09-01

    Two cross-sectional studies investigated media influences on adolescents' substance use and intentions to use substances in the context of exposure to parental and peer risk and protective factors. A total of 729 middle school students (n = 351, 59% female in Study 1; n = 378, 43% female in Study 2) completed self-report questionnaires. The sample in Study 1 was primarily African-American (52%) and the sample in Study 2 was primarily Caucasian (63%). Across the two studies, blocks of media-related cognitions made unique contributions to the prediction of adolescents' current substance use and intentions to use substances in the future above and beyond self-reported peer and parental influences. Specifically, identification with and perceived similarity to media messages were positively associated with adolescents' current substance use and intentions to use substances in the future, and critical thinking about media messages and media message deconstruction skills were negatively associated with adolescents' intention to use substances in the future. Further, peer influence variables (e.g., peer pressure, social norms, peer substance use) acted as risk factors, and for the most part, parental influence variables (e.g., parental pressure to not use, perceived parental reaction) acted as protective factors. These findings highlight the importance of developing an increased understanding of the role of media messages and media literacy education in the prevention of substance use behaviors in adolescence.

    2018-01-01

    We describe the preparation, evaluation, and application of an S100A12 protein-conjugated solid support, hereafter the “A12-resin,” that can remove 99% of Zn(II) from complex biological solutions without significantly perturbing the concentrations of other metal ions. The A12-resin can be applied to selectively deplete Zn(II) from diverse tissue culture media and from other biological fluids, including human serum. To further demonstrate the utility of this approach, we investigated metabolic, transcriptomic, and metallomic responses of HEK293 cells cultured in medium depleted of Zn(II) using S100A12. The resulting data provide insight into how cells respond to acute Zn(II) deficiency. We expect that the A12-resin will facilitate interrogation of disrupted Zn(II) homeostasis in biological settings, uncovering novel roles for Zn(II) in biology. PMID:29334734

    Doub, Allison E; Small, Meg; Birch, Leann L

    2016-04-01

    There is increasing interest in leveraging social media to prevent childhood obesity, however, the evidence base for how social media currently influences related behaviors and how interventions could be developed for these platforms is lacking. This commentary calls for research on the extent to which mothers use social media to learn about child feeding practices and the mechanisms through which social media influences their child feeding practices. Such formative research could be applied to the development and dissemination of evidence-based childhood obesity prevention programs that utilize social media. Mothers are identified as a uniquely important target audience for social media-based interventions because of their proximal influence on children's eating behavior and their high engagement with social media platforms. Understanding mothers' current behaviors, interests, and needs as they relate to their social media use and child feeding practices is an integral first step in the development of interventions that aim to engage mothers for obesity prevention. This commentary highlights the importance of mothers for childhood obesity prevention; discusses theoretical and analytic frameworks that can inform research on social media and mothers' child feeding practices; provides evidence that social media is an emerging context for social influences on mothers' attitudes and behaviors in which food is a salient topic; and suggests directions for future research.

    Kun, Tomasz; Jakubowski, Lucjusz

    2012-07-01

    Mast cells, owing to diversity of secreted mediators, play a crucial role in the regulation of inflammatory response. Together with basophils, mast cells constitute a central pathogenetic element of anaphylactic (IgE-dependent) and anaphylactoid (IgE-independent) reactions. In severe cases, generalized degranulation of mast cells may cause symptoms of anaphylactic shock. The influence of the classical, iodine-based contrast media on mastocyte degranulation has been fully described. Our objective was to determine the influence of the gadolinium-based MRI contrast media on histamine release from mast cells and to compare the activity of ionic and non-ionic preparations of contrast media. To determine the intensity of mast cell degranulation, we used an experimental model based on mastocytes isolated from rat peritoneal fluid. Purified suspensions of mast cells were incubated with various concentrations of Gd-DTPA and Gd-DTPA-BMA, and solutions of PEG 600 which served as a non-toxic osmotic stimulus. The intensity of mast cell activation was presented as mean percentage of histamine released from cells after incubation. The obtained results demonstrate that both ionic and non-ionic preparations of the MRI contrast media are able to induce mast cell degranulation in vitro. It was also proved that the non-ionic MRI contrast media stimulate mast cells markedly more weakly than ionic contrast media at identical concentration. The aforementioned results may suggest a more profitable safety profile of the non-ionic contrast preparations. We may also conclude that triggering of mast cell degranulation after incubation with the solutions of MRI contrast media results from non-specific osmotic stimulation and direct toxicity of free ionic residues.

    2008-07-01

    We study an extension of Axelrod's model for social influence, in which cultural drift is represented as random perturbations, while mass media are introduced by means of an external field. In this scenario, we investigate how the modular structure of social networks affects the propagation of mass media messages across a society. The community structure of social networks is represented by coupled random networks, in which two random graphs are connected by intercommunity links. Considering inhomogeneous mass media fields, we study the conditions for successful message spreading and find a novel phase diagram in the multidimensional parameter space. These findings show that social modularity effects are of paramount importance for designing successful, cost-effective advertising campaigns.

    2007-11-01

    Few studies have directly assessed the impact of a specific media report in vulnerable people. This study investigates possible influences of media reporting of a celebrity suicide on subsequent suicidal behaviors and associated risk factors among depressive patients. Depressive patients (N=461) were assessed through a structured interview soon after extensive media reporting of a celebrity suicide. Among 438 depressive patients exposed to the media report, 38.8% reported an influence on subsequent suicidal behaviors, including 24 (5.5%) with a suicide attempt. The risk of such influence was highest among patients in a severe depressive state just prior to the media report (adjusted OR 7.81, 95% CI 3.28-18.59). Such influence on a subsequent suicide attempt was highest in patients with a most recent suicide attempt within one month prior to the media reports (adjusted hazard ratio 11.91, 95% CI 3.76-37.72). Our finding of the significant media influence may reflect adverse thoughts among more suicidal and depressed individuals. The possible influence of other factors on the findings cannot be ruled out. This study has provided more convincing evidence suggesting negative influences of media reporting of a celebrity suicide on subsequent suicidal behaviors among depressive patients. Particular attention in terms of potential negative media influences should be paid to patients who are younger and currently depressed and have made a recent suicide attempt.

    2012-02-01

    OBJECTIVE: EPICA is the first large-scale Irish study of a school-going population examining the impact of media influences on eating attitudes. METHOD: Students were screened using the EAT-26, EDI-III and a study-specific questionnaire. A sub-sample of parents\\' views was included. RESULTS: Three thousand and thirty-one students (mean age 14.74) and 56 parents enrolled. The majority (71.4%) of adolescents felt adversely affected by media portrayal of body weight and shape, with more than a quarter (25.6%) believing it to be \\'far too thin\\'. A significant correlation between media impact and high EAT scores (chi2 = 450.78, df = 2, p < 0.05) and EDI-III scores (chi2 = 387.51, df = 4, p < 0.05) was demonstrated. Parents also view media portrayal as too thin (94.7%), less than half are adversely affected by it (49.2%) but the majority (71.9%) believe their children to be. CONCLUSION: Media portrayal of body weight and shape is correlated with eating psychopathology and may affect adolescents more than adults. School psycho-educational programmes and media policies are urgently needed to minimise any detrimental effect.

    Medical societies, faculty, and trainees use Twitter to learn from and educate other social media users. These social media communities bring together individuals with various levels of experience. It is not known if experienced individuals are also the most influential members. We hypothesize that participants with the greatest experience would be the most influential members of a Twitter community. We analyzed the 2013 Association of Program Directors in Internal Medicine Twitter community. We measured the number of tweets authored by each participant and the number of amplified tweets (re-tweets). We developed a multivariate linear regression model to identify any relationship to social media influence, measured by the PageRank. Faculty (from academic institutions) comprised 19% of the 132 participants in the learning community (p influence amongst all participants (mean 1.99, p influence (β = 0.068, p = 0.6). The only factors that predicted influence (higher PageRank) were the number of tweets authored (p influence. Any participant who was able to author the greatest number of tweets or have more of his/her tweets amplified could wield a greater influence on the participants, regardless of his/her authority.

    2012-01-01

    While there is a large body of work examining the effects of social network structure on innovation adoption, models to date have lacked considerations of real geography or mass media. In this article, we show these features are crucial to making more accurate predictions of a social contagion and technology adoption at a city-to-city scale. Using data from the adoption of the popular micro-blogging platform, Twitter, we present a model of adoption on a network that places friendships in real geographic space and exposes individuals to mass media influence. We show that homophily both among individuals with similar propensities to adopt a technology and geographic location is critical to reproducing features of real spatiotemporal adoption. Furthermore, we estimate that mass media was responsible for increasing Twitter's user base two to four fold. To reflect this strength, we extend traditional contagion models to include an endogenous mass media agent that responds to those adopting an innovation as well as influencing agents to adopt themselves.

    Many institutions use social media to share research with the general public. However, the influence of social media on the dissemination of a surgical research article itself is unknown. Our objective was to determine whether a blog post highlighting the findings of a surgical research article would lead to increased dissemination of the article itself. We prospectively followed the online page views of an article that was published online in Surgery in May 2015 and published in print in August 2015. The authors subsequently released a blog post in October 2015 to promote the research. The number of article page views from the journal's website was obtained before and after the blog post, along with the page views from the blog post itself. Social media influence data were collected, including social activity in the form of mentions on social media sites, scholarly activity in online libraries, and scholarly commentary. The article's online activity peaked in the first month after online publication (475 page views). Online activity plateaued by 4 months after publication, with 118 monthly page views, and a blog post was subsequently published. The blog post was viewed by 1566 readers, and readers spent a mean of 2.5 minutes on the page. When compared to the projected trend, the page views increased by 33% in the month after the blog post. The blog post resulted in a 9% increase in the social media influence score and a 5% absolute increase in total article page views. Social media is an important tool for sharing surgical research. Our data suggest that social media can increase distribution of an article's message and also potentially increase dissemination of the article itself. We believe that authors should consider using social media to increase the dissemination of traditionally published articles. Copyright © 2016 Association of Program Directors in Surgery.

    2016-06-01

    Full Text Available Social media has transformed the way we think our campaigns and communicate with our audience, but also it changed the way we get in touch with our target and make it react to what we are saying or doing. The objective of this paper is to emphasize that we not only use social media on a personal level, but we’ve transformed it in an important marketing tool for our business. Today we live in online almost as much as we live in the real world. A company without a website and social media presence it does not exists. For researchers and headhunters, social media have become an important tool. So we have to be careful with things we post online, because they can say a lot of things about us and can influence our professional development. The fundaments for this paper are based mainly on the following studies: (1 “Social Media and the Romanian Business Milieu – Impact of Marketing through Social Media on Local Business Environment”, published in October 2013, by Ernst & Young, (2 “Social Media Primetime Survey”, publish by the Romanian consultancy and training company The Connector, (3 “Online Landscape – South-East Europe”, published by Gemius Knowledge, in 2014 and (4 “Online Social Networks”, by Daedalus MillwardBrown, published in 2011. They all show how social media and online development have impacted on traditional media and how companies cannot ignore these new communication and business channels. Studies on social media also showed that internet and mobile platforms are getting more and more popular, that people and companies are drowned into the digital world, communicating through all types of apps and networks. Used wisely, social media can generate greater and faster results with less money than traditional media (print, television, radio, outdoor. The sources used for this paper say that social media is “the it thing” in the 21st century, when almost every person on the planet has a cell phone or access to one

  2. Media and Influence

    Science.gov (United States)

    Bennett, William H.

    The public information media provides information on current events (news), entertainment (programming), and opinions offered by trusted public sources (e.g., business, academic or religious spokespersons, journalists, and government officials). Consequently, it is a major force in shaping a populace's attitudes toward significant social issues and of great interest to intervention planners. The chapter attempts to provide modelers and intervention analysts alike with sufficient understanding of media mechanisms and current research that they can begin contributing to, and benefiting from this important area of study.

    Based on Cichlidogyrus sp. (Monogenea, Ancyrocephalidae) specimens from Hemichromis sp. hosts, we tested the influence of different methods to fix/preserve samples/specimens [frozen material, alcohol or formalin preserved, museum process for fish preservation (fixed in formalin and preserved in alcohol)] and different media used to mount the slides [tap water, glycerin ammonium picrate (GAP), Hoyer's one (HM)] on the size/shape of sclerotized parts of monogenean specimens. The results show that the use of HM significantly increases the size of haptoral sclerites [marginal hooks I, II, IV, V, and VI; dorsal bar length, width, distance between auricles and auricle length, ventral bar length and width], and changes their shape [angle opening between shaft and guard (outer and inner roots) in both ventral and dorsal anchors, ventral bar much wider, dorsal one less curved]. This influence seems to be reduced when specimens/samples are fixed in formalin. The systematics of Monogenea being based on the size and shape of their sclerotized parts, to prevent misidentifications or description of invalid new species, we recommend the use of GAP as mounting medium; Hoyer's one should be restricted to monogenean specimens fixed for a long time which are more shrunken.

    The rate of contralateral prophylactic mastectomy (CPM) has risen sharply in the past decade. The current study was designed to examine social network, surgeon, and media influence on patients' CPM decision-making, examining not only who influenced the decision, and to what extent, but also the type of influence exerted. Patients (N=113) who underwent CPM at 4 Indiana University-affiliated hospitals between 2008 and 2012 completed structured telephone interviews in 2013. Questions addressed the involvement and influence of the social network (family, friends, and nonsurgeon health professionals), surgeon, and media on the CPM decision. Spouses, children, family, friends, and health professionals were reported as exerting a meaningful degree of influence on patients' decisions, largely in ways that were positive or neutral toward CPM. Most surgeons were regarded as providing options rather than encouraging or discouraging CPM. Media influence was present, but limited. Patients who choose CPM do so with influence and support from members of their social networks. Reversing the increasing choice of CPM will require educating these influential others, which can be accomplished by encouraging patients to include them in clinical consultations, and by providing patients with educational materials that can be shared with their social networks. Surgeons need to be perceived as having an opinion, specifically that CPM should be reserved for those patients for whom it is medically indicated.

    Full Text Available Social media is becoming an important part of an organization's media strategy. This study examines the effects of trust and consumer emotional response to advertisements on brand evaluation in an online social media context. The study used a survey method, and the studied population consisted of 927 Brazilian social media users (Facebook subscribers. The results showed the following: (1 the emotional response to advertising on social media had a positive influence on brand evaluation; and (2 consumer trust had a positive influence on brand evaluation and emotional response to advertisements on social media. It is possible to conclude that consumer trust is the key variable to a positive emotional response to advertisements on social media and to a positive brand evaluation. Finally, this study demonstrates that companies must measure the emotional response to advertising in their social media activities as a way of enhancing brand evaluation.

  6. Presuming the influence of the media: teenagers' constructions of gender identity through sexual/romantic relationships and alcohol consumption.

    Using empirical data from group discussions and in-depth interviews with 13 to 15-year olds in Scotland, this study explores how teenagers' alcohol drinking and sexual/romantic relationships were shaped by their quest for appropriate gendered identities. In this, they acknowledged the influence of the media, but primarily in relation to others, not to themselves, thereby supporting Milkie's 'presumed media influence' theory. Media portrayals of romantic/sexual relationships appeared to influence teenagers' constructions of gender-appropriate sexual behaviour more than did media portrayals of drinking behaviour, perhaps because the teenagers had more firsthand experience of observing drinking than of observing sexual relationships. Presumed media influence may be less influential if one has experience of the behaviour portrayed. Drinking and sexual behaviour were highly interrelated: sexual negotiation and activities were reportedly often accompanied by drinking. For teenagers, being drunk or, importantly, pretending to be drunk, may be a useful way to try out what they perceived to be gender-appropriate identities. In sum, teenagers' drinking and sexual/romantic relationships are primary ways in which they do gender and the media's influence on their perceptions of appropriate gendered behaviour is mediated through peer relationships. © 2014 The Authors.

    Full Text Available Computerization, digitalization and datafication are by far no neutral or self-dependent occurrences. They are, to a large degree, co-determined by heterogeneous actors who reflect about, construct, configure, manipulate or even control media. The contributors to this issue put the spotlight on these actors and investigate how they influence, shape and (reconfigure broader social constellations. Instead of exploring what people do with media, the articles focus on the many ways individuals, civil society initiatives, corporations and social movements act on media. The notion of acting on media denotes the efforts of a wide range of actors to take an active part in the molding of media organizations, infrastructures and technologies that are part of the fabric of everyday life. Therefore, by conceptualizing acting on media as a form of political action, the issue aims to contribute to ongoing discussions on the media practice paradigm.

  8. Modeling the adoption of innovations in the presence of geographic and media influences.

    Jameson L Toole

    Full Text Available While there is a large body of work examining the effects of social network structure on innovation adoption, models to date have lacked considerations of real geography or mass media. In this article, we show these features are crucial to making more accurate predictions of a social contagion and technology adoption at a city-to-city scale. Using data from the adoption of the popular micro-blogging platform, Twitter, we present a model of adoption on a network that places friendships in real geographic space and exposes individuals to mass media influence. We show that homophily both among individuals with similar propensities to adopt a technology and geographic location is critical to reproducing features of real spatiotemporal adoption. Furthermore, we estimate that mass media was responsible for increasing Twitter's user base two to four fold. To reflect this strength, we extend traditional contagion models to include an endogenous mass media agent that responds to those adopting an innovation as well as influencing agents to adopt themselves.

    Full Text Available Previous research has emphasised social media adoption by students and the implementation of social media by educators, yet few studies have explored whether students are using it to facilitate engagement in offline environments with peers within university communities. Studies suggest engagement in educational communities and extra-curricular activities can reduce student attrition. This study surveyed 106 undergraduate students to investigate whether students using social media to interact online with their university felt: (i connected to the broader university community, and (ii social media helped them engage offline by meeting up with peers and attending university events. The results indicated that the majority (82% never or rarely used the technology to facilitate offline engagement within their academic communities. Fourth year students were most likely to use social media to engage offline (66.7%. However, more than half of students (52.8% felt that university social media profiles helped them to feel part of their academic community.

    Eating disorders (ED) can be influenced by psychological and socio-cultural factors. The aim of this study was to explore the association between parental and media influences and body image concerns as factors in the onset of ED. A cross-sectional study was conducted among 662 students (407 women and 255 men) attending one of three universities in United Arab Emirates (UAE). The study employed an online self-administered questionnaire with validated scales: Eating Attitudes Test-26 (EAT-26), Body Shape Questionnaire (BSQ), Media Influences Scale, and Family Influences Scale (FIS). About 33% of the sample had EAT- 26 scores >=20 and 45% showed mild to marked concerns about their body shape. Women students were significantly more concerned about their shape, and more influenced by media than men. There were significant differences in the means of all scores, except for media influence, among the four BMI groups. The EAT-26 score showed strongest correlation with BSQ (r=0.48), followed by FIS, Media and BMI (r=0.419, r=0.276 and r=0.18 respectively). The BSQ was the best predictor of ED and was inversely associated with the EAT-26 score (B=-1.51, OR=0.219, 95% CI: 0.152-0.316, pmedia and families exert on the development of ED among young adults. These findings provide baseline data for future longitudinal studies to investigate factors influencing ED.

    2014-01-01

    This study uses the influence of presumed media influence model as the theoretical framework to examine how perceived social norms (i.e., descriptive, subjective, and injunctive norms) will mediate the influence of pro- and antidrinking media messages on adolescents' intention to consume alcohol in rural Thailand. Data collected from 1,028 high school students indicate that different mechanisms underlie drinking intentions between nondrinkers and those who have consumed alcohol or currently drink. Among nondrinkers, perceived peer attention to prodrinking messages indirectly influenced adolescents' prodrinking attitudes and intentions to consume alcohol through all three types of perceived social norms. Among drinkers, perceived peer attention to pro- and antidrinking messages indirectly influenced adolescents' prodrinking attitudes and intentions to drink alcohol through perceived subjective norm. The findings provide support for the extended influence of presumed media influence model and have practical implications for how antidrinking campaigns targeted at teenagers in Thailand might be designed.

    Full Text Available In modern business conditions, it is possible to identify a number of manners for company's communication with current customers and prospects. That is the reason for marketers to prioritize the requirements of finding an adequate mix of integrated marketing communications instruments, defining their roles and the extent to which they should be implemented, as well as their mutual coordination and synergetic effects. Company can use different media and, by their combination and integration, send a clear and consistent promotional message to customers. In this paper, the authors analyse the perceived impact of the media and their combination on consumers' attitudes towards food products and their intention to buy food products, as well as whether there are differences when it comes to these influences among consumers with different socio-demographic characteristics.

  18. Media and politics: Empirical data on their cross-influence in health policy.

    2011-01-01

    OBJECTIVES: Despite the central influence of public policies on health and welfare, relatively little is known about actual health care policy-making processes. This presentation will offer preliminary results from a federally funded project aimed at gaining insights into the interrelations among interest-group strategies, media discourses and political debates in health care. The policy debate on health care privatization in Quebec is used as a case study. APPROACH: Two sources of data were used: media sources and political debates. Media sources were the six main provincial newspapers in Quebec, two national newspapers and The Canadian Press, as well as transcripts from specific news-related programs of three national television stations and two national radio stations. Political debates were obtained through transcripts of all question periods in the Parliament and debates in the standing committee on health. Sources were systematically searched to identify all relevant data. Multiple search syntaxes were developed and tested to maximize sensitivity and specificity. All data was entered and coded into qualitative analysis software. RESULTS: Data was analyzed longitudinally from June 2005 to January 1, 2010. Four levels of results will be presented: 1) Descriptive analysis of the interest groups involved, their policy preferences and the rhetoric they employed to support their views. 2) Descriptive analysis of the main policy proposals that structured the debate as well as of the coalition of groups behind those proposals. 3) Graphic longitudinal analysis of the intensity of the debate and of the relative importance and evolution of various policy proposals. 4) Preliminary results on the nature, direction and level of inter-influence between the policy and media agendas. CONCLUSION: This presentation provides empirical evidence on current policy-making processes in health care. It shows, unsurprisingly, that policy-making is a circumvoluted process of inter-influence

    2011-01-01

    Previous studies of social influences on adolescent smoking have focused on peers and parents, using data collected prior the 1998 Master Settlement Agreement. This study used the 2004 wave of the National Youth Tobacco Survey to examine associations between peer smoking, smoking at home, tobacco-related media exposure, and smoking behavior during early and middle adolescence. Findings indicate that peer smoking and smoking at home remain strongly associated with current smoking among early and middle adolescents, controlling for gender, race/ethnicity and exposure to tobacco industry and anti-tobacco media. The magnitude of the association between peer smoking and current smoking decreases from early adolescence to middle adolescence while the association between smoking at home and current smoking is static across developmental stage. Exposure to tobacco-related media is associated with increased current and former smoking in both early and middle adolescence. Copyright © 2010 Elsevier Ltd. All rights reserved.

    2013-01-01

    The purpose of this article is to present findings from two parallel qualitative studies that used focus groups to explore adolescent views of psychological wellness and healthy bodies. Nine focus groups were held with 46 adolescents aged 16-19 years from two Mid-Western Canadian high schools. Both studies were designed with an interpretive humanist perspective and then a 6-step thematic approach was used to analyze the data. Common themes emerging in the focus group discussions in both studies included the negative impact of media on adolescent body image and pressure to conform to the Western views of physical appearance. These findings illustrate the need for nurses to understand the influence of the media on adolescents' views of their body image and to incorporate protocols for assessment, education, and counseling of adolescents on the healthy usage of media into their pediatric clinical practice. Through consistent participation in the development and implementation of health policies, nurses play a critical role in supporting adolescents to develop healthy views of body image.

    Major social networking platforms, such as Facebook, WhatsApp, and Twitter, have become popular means through which people share health-related information, irrespective of whether messages disseminated through these channels are authentic. This study aims to describe the demographic characteristics of patients that may demonstrate their attitudes toward medical information shared on social media networks. Second, we address how information found through social media affects the way people deal with their health. Third, we examine whether patients initiate or alter/discontinue their medications based on information derived from social media. We conducted a cross-sectional survey between April and June 2015 on patients attending outpatient clinics at King Abdulaziz University, Jeddah, Saudi Arabia. Patients who used social media (Facebook, WhatsApp, and Twitter) were included. We designed a questionnaire with closed-ended and multiple-choice questions to assess the type of social media platforms patients used and whether information received on these platforms influenced their health care decisions. We used chi-square test to establish the relationship between categorical variables. Of the 442 patients who filled in the questionnaires, 401 used Facebook, WhatsApp, or Twitter. The majority of respondents (89.8%, 397/442) used WhatsApp, followed by Facebook (58.6%, 259/442) and Twitter (42.3%, 187/442). In most cases, respondents received health-related messages from WhatsApp and approximately 42.6% (171/401) reported ever stopping treatment as advised on a social media platform. A significantly higher proportion of patients without heart disease (P=.001) and obese persons (P=.01) checked the authenticity of information received on social media. Social media messages influenced decision making among patients without heart disease (P=.04). Respondents without heart disease (P=.001) and obese persons (P=.01) were more likely to discuss health-related information

    The AGREE II instrument is the most commonly used guideline appraisal tool. It includes 23 appraisal criteria (items) organized within six domains. AGREE II also includes two overall assessments (overall guideline quality, recommendation for use). Our aim was to investigate how strongly the 23 AGREE II items influence the two overall assessments. An online survey of authors of publications on guideline appraisals with AGREE II and guideline users from a German scientific network was conducted between 10th February 2015 and 30th March 2015. Participants were asked to rate the influence of the AGREE II items on a Likert scale (0 = no influence to 5 = very strong influence). The frequencies of responses and their dispersion were presented descriptively. Fifty-eight of the 376 persons contacted (15.4%) participated in the survey and the data of the 51 respondents with prior knowledge of AGREE II were analysed. Items 7-12 of Domain 3 (rigour of development) and both items of Domain 6 (editorial independence) had the strongest influence on the two overall assessments. In addition, Items 15-17 (clarity of presentation) had a strong influence on the recommendation for use. Great variations were shown for the other items. The main limitation of the survey is the low response rate. In guideline appraisals using AGREE II, items representing rigour of guideline development and editorial independence seem to have the strongest influence on the two overall assessments. In order to ensure a transparent approach to reaching the overall assessments, we suggest the inclusion of a recommendation in the AGREE II user manual on how to consider item and domain scores. For instance, the manual could include an a-priori weighting of those items and domains that should have the strongest influence on the two overall assessments. The relevance of these assessments within AGREE II could thereby be further specified.

    Newspapers, in addition to news, also cover topics of permanent interest to their readers. One such topic is sexuality. The appearance of the incurable sexually transmitted disease AIDS obliges a reconsideration of the complex and contradictory concept of sexuality. Sexuality is not often spoken of openly; rather, it is secret, hidden, and referred to obliquely. Sexuality is the manifestation and satisfaction of the sexual impulses common to all individuals. Sexuality is determined by anatomic and physiologic aspects and also by the knowledge, experiences, values, and norms internalized by the individual living in a social group. Messages about sexual conduct are constantly being received. This social part of sexuality supported by customs and morals is the part that is directly influenced by communications media. An important objective of the media is to create awareness and mold opinions. Mexico's large national circulation newspapers present different points of view about sexuality. Newspapers that continually critique homosexual practices and those that demonstrate implicit approval of pornographic videos by advertising them both present attitudes without providing opportunities to reason, compare, or support opinions. Sexuality is usually referred to indirectly and superficially in the press. Sex education may be mentioned but not the erotic implications of sexuality, and acceptance or opposition to use of condoms may be discussed without mention of psychological barriers to their use. The national press is not prepared to propose new attitudes toward sexuality in the age of AIDS. Only 1 national newspaper in Mexico regularly provides information on AIDS including aspects related to sexual pleasure and responsibility and safer sex. The majority continue with their pre-AIDS coverage of sexuality, using it to arouse interest but providing little depth. Newspapers should provide more extensive coverage on sexuality and its modifications due to AIDS, a reality

    Highlights: → We model the diffusion of Ni(II) through bentonite using different sorption models. → We examine sorption competition of Fe(II) and Ni(II) at different concentrations. → Ni(II) breakthrough is 15 times earlier with Fe(II) sorption competition. → Ni(II) sorption is non-linear and depends on the Fe(II) concentration levels. → Sorption competition is important and has to be modelled by reactive transport codes. - Abstract: The results from batch sorption experiments on montmorillonite systems have demonstrated that bivalent transition metals compete with one another for sorption sites. For safety analysis studies of high level radioactive waste repositories with compacted bentonite near fields, the importance of competitive sorption on the migration of radionuclides needs to be evaluated. Under reducing conditions, the bentonite porewater chosen has a Fe(II) concentration of ∼5.3 x 10 -5 M through saturation with siderite. The purpose of this paper is to assess the influence of such high Fe(II) concentrations on the transport of Ni(II) through compacted bentonite, Ni(II) was chosen as an example of a bivalent transition metal. The one-dimensional calculations were carried out at different Ni(II) equilibrium concentrations at the boundary (Ni(II) EQBM ) with the reactive transport code MCOTAC incorporating the two site protolysis non electrostatic surface complexation/cation exchange sorption model, MCOTAC-sorb. At a Ni(II) EQBM level of 10 -7 M without Fe(II) competition, the reactive transport calculations using a constant K d approach and the MCOTAC-sorb calculation yielded the same breakthrough curves. At higher Ni(II) EQBM (10 -5 M), the model calculations with MCOTAC-sorb indicated a breakthrough which was shifted to later times by a factor of ∼5 compared with the use of the constant K d approach. When sorption competition was included in the calculations, the magnitude of the influence depended on the sorption characteristics of the

    Mass media plays an important role in communicating about health research and services to patients, and in shaping public perceptions and decisions about health. Healthcare professionals also play an important role in providing patients with credible, evidence-based and up-to-date information on a wide range of health issues. This study aims to explore primary care nurses' experiences of how mass media influences frontline healthcare. In-depth telephone interviews were carried out with 18 primary care nurses (nine health visitors and nine practice nurses) working in the United Kingdom (UK). Interviews were recorded and transcribed. The data was analysed using thematic analysis, with a focus on constant comparative analysis. Three themes emerged from the data. First, participants reported that their patients were frequently influenced by controversial health stories reported in the media, which affected their perceptions of, and decisions about, care. This, in turn, impinged upon participants' workloads as they had to spend additional time discussing information and reassuring patients. Second, participants also recalled times in their own careers when media reports had contributed to a decline in their confidence in current healthcare practices and treatments. Third, the participants in this study suggested a real need for additional resources to support and expand their own media literacy skills, which could be shared with patients. In an ever expanding media landscape with greater reporting on health, nurses working in the primary care setting face increasing pressure to effectively manage media stories that dispute current health policies and practices. These primary care nurses were keen to expand their media literacy skills to develop critical autonomy in relation to all media, and to facilitate more meaningful conversations with their patients about their health concerns and choices.

    Ozonation of two azo dyes was investigated in a monitored bench scale bubble column reactor (8.5-L), varying liquid media salt content (0, 1, 40 and 100 g L -1 , NaCl). In experiments with Orange II pH was varied (5, 7.5 and 9) but ozonation of Acid Red 27 was performed at pH 7.5. Ozone self-decomposition rate-constant increased with salt concentration. Color removal was very effective and fast achieved under all experimental conditions. For the two azo dyes tested, more than 98% of color intensity was removed in 30-min ozonation assays. However, only partial mineralization of azo dyes (45%-Orange II; 20%-Acid Red 27) was attained in such experiments. The degree of mineralization (TOC removal) was negatively affected by salt concentration. Biodegradation assays conducted by respirometry revealed the inhibitory effect of dye degradation products formed during ozonation.

    to discuss the influence of media coverage in spreading and controlling of adopter of a particular product in a region. The model exhibits two equilibria:(i a adopter-free and (ii unique interior equilibrium. Stability analysis of the model shows that the adopter-free equilibrium is always locally asymptotically stable if the influence number of adopter $(R_0$, which depends on parameters of the system is less than unity. Otherwise if $R_0>1$, a unique interior equilibrium exists, it is locally asymptotically stable under some set of conditions. Further analytically and numerically it is observed that the region for backward bifurcation of adopter population increases with the decrease of the valid contact rate before media alert. Finally, numerically experimentations are presented to establish the effect of different media alert rate on adopter and non adopter population.

  20. The influence of transverse diffusion/dispersion on the migration of radionuclides in porous media

    Repositories in geological formations are planned for the final disposal of radioactive wastes produced by nuclear power. Generally, water entry leading to leaching of the waste matrix is considered as the critical process which can result in release of radionuclides from a waste repository. Consequently, radionuclide transport through the geosphere is of crucial importance, because the geological medium acts as the last barrier to the biosphere. The influence of the transverse diffusion/dispersion effect on the migration of radionuclides through the geosphere is dealt with. Migration in porous media only is considered which is the standard approach of most existing transport models. The present study shows that it is only for homogeneous-isotropic media that the three-dimensional time-dependent transport equation can be solved analytically - provided that only simple source geometries and leach processes are taken into account. For heterogeneous layered media only the two-dimensional quasi-stationary transport equation can be solved; the only time dependent process which can be handled is simple radioactive decay excluding extended decay chains. The study shows moreover that only for an idealized three-layer geology can analytical solutions be found. In particular the solutions for multi-layered media cannot be derived from single-layer solutions; each problem with special source and boundary conditions has to be solved directly. The numerical results from the present study show a relatively strong influence of the transverse dispersion effect in the case of homogeneous-isotropic media. (Auth.)

    Full Text Available People’s empowerment could be done in several ways in all elements of society. One of the ways is by taking advantage of media for the Fishermen. Fishermen have a lot to fix in terms of their business system. On the other hand, in order to have an appropriate competence and to take advantage of business opportunities, the use of media to get the information and to gain new knowledge is highly needed. This research is conducted in Pasaran Island since it is the center of fish processing in Kota Bandar Lampung. The sample of this research is the whole group members of fishermen as many as 125 people. The research data collected consist of primary and secondary data, and then these data are tested with rank Spearman and path analysis correlation statistics. The result of this research shows that based on the rank Spearman correlation analysis, the factors related to the use of communication media result age and education level have high correlations with the use of media. The number of family dependents, the length of work as a fisherman and also the income do not have high correlations with the use of communication media. From the path analysis, it is revealed that fishermen’s characteristics have direct influences on fishermen’s empowerment but they also have indirect influences as well by the use of media means. Those refer to age and education level.

    Full Text Available This paper examines the ways rural businesses can become attractive to millennials using the Internet and the social media. It has become evident that the prominent way to reach out to millennials is via social media accounts. Rural businesses need to use the personal relationships they develop with their customers and expand these relationships on social media. It is also apparent that traditional marketing fails to apply to small rural businesses, whereas influencer marketing becomes a valuable asset for tourism. The proposed model connects fame, image and activities with the Social Media influencer and the way the decision making of the millennials is influenced when choosing to visit a rural tourism destination.

    This study explores the relationships between consumers and mobile advertisements on attitude change over time. Two experiments were used to investigate both immediate and delayed effects of different media types on attitudes toward mobile advertisements. Experiment 1 formulated three types of advertisements corresponding to three media types: text, still pictures, and motion pictures. The results indicate that motion pictures on mobile phones significantly influence consumers' initial attitudes toward advertisements. Experiment 2, focusing on delayed effects, was conducted 4 weeks after Experiment 1. Ninety-five of the 117 participants in Experiment 1 were contacted via cellular phone. The results of Experiment 2 showed a decrease in attitude in relation to motion pictures, whereas an increase in attitude in relation to text and still pictures was observed. The findings were interpreted from the perspectives of media characteristics, consumer behavior, and advertising research.

    Eating disorders (EDs) are a public health problem, and their relationship to mass media is still controversial. To assess whether there is an association between models of body image shown in mass media and the risk of developing EDs among female adolescent students from Lima, Peru. Cross-sectional study conducted in three schools located in the district of La Victoria, Lima, Peru. The risk of developing EDs was measured using the Eating Attitudes Test-26 (EAT-26), while mass media influence was measured using the Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3), which was categorized into tertiles both in the overall score and its subscales (information, pressure, general internalization, and athletic internalization). Adjusted prevalence ratios (aPR) for EDs were estimated. Four hundred and eighty-three students were included, their median age was 14 ? 3 years old. A risk of developing an ED was observed in 13.9% of them. Students who are more influenced by mass media (upper tertile of the SATAQ-3) have a higher probability of having a risk of developing an ED (aPR: 4.24; 95% confidence interval |-CI-|: 2.10-8.56), as well as those who have a greater access to information (PR: 1.89; 95% CI: 1.09-3.25), suffer more pressure (PR: 4.97; 95% CI: 2.31-10.69), show a greater general internalization (PR: 5.00; 95% CI: 2.39-10.43), and show a greater level of athletic internalization (PR: 4.35; 95% CI: 2.19-8-66). The greater the influence of mass media, the greater the probability of having a risk of developing an ED among female students from Lima, Peru.

    The use of dyadic interaction between agents, in combination with homophily (the principle that “likes attract”) in the Axelrod model for the study of cultural dissemination, has two important problems: the prediction of monoculture in large societies and an extremely narrow window of noise levels in which diversity with local convergence is obtained. Recently, the inclusion of social influence has proven to overcome them [A. Flache and M. W. Macy, e-print arXiv:0808.2710]. Here, we extend the Axelrod model with social influence interaction for the study of mass media effects through the inclusion of a superagent which acts over the whole system and has non-null overlap with each agent of the society. The dependence with different parameters as the initial social diversity, size effects, mass media strength, and noise is outlined. Our results might be relevant in several socioeconomic contexts and for the study of the emergence of collective behavior in complex social systems.

  8. Medicine in the popular press: the influence of the media on perceptions of disease.

    Directory of Open Access Journals (Sweden)

    Meredith E Young

    Full Text Available In an age of increasing globalization and discussion of the possibility of global pandemics, increasing rates of reporting of these events may influence public perception of risk. The present studies investigate the impact of high levels of media reporting on the perceptions of disease. Undergraduate psychology and medical students were asked to rate the severity, future prevalence and disease status of both frequently reported diseases (e.g. avian flu and infrequently reported diseases (e.g. yellow fever. Participants considered diseases that occur frequently in the media to be more serious, and have higher disease status than those that infrequently occur in the media, even when the low media frequency conditions were considered objectively 'worse' by a separate group of participants. Estimates of severity also positively correlated with popular print media frequency in both student populations. However, we also see that the concurrent presentation of objective information about the diseases can mitigate this effect. It is clear from these data that the media can bias our perceptions of disease.

  9. In-vitro effects of tri-iodinated X-ray contrast media on blood coagulation, fibrinolysis and complement system

    1982-01-01

    In-vitro experiments with Jodipamid, Jothalamat and Diatrizoat served the purpose of determining influences of contrast media on blood coagulation, fibrinolysis and the complement system. For all three contrast media investigated the effect noted was dose-dependent and was only brought about by concentrations higher than physiological ones. Liver-pathway Jodipamid was seen to have a much stronger effect than the two renal-pathway contrast media Jothalamat and Diatrizoat, which is probably due to the different protein binding capacities. In detail, the results with Jodipamid were as follows: a sharp fall in thrombinogen, a distinct decrease in fibrinogen both in the immunological and functional test, but only delayed decrease in complement factor C 4. Fibrinolytic fission products were found after applying the dose of 30 mM, as compared to 400 mM for the renal-pathway contrast media. Furthermore the functional tests (F I and F II) with Jothalamat and Diatrizoat showed only slight effects, the immunological ones (F I and C 4) none at all. The influence of the contrast media on factors I and II is interpreted by the author as an inhibition of fibrin polymerization. What seems to be the verification of fibrinolytic fission products is explained by a non-specific agglutination reaction, the decrease in C 4 by contrast-medium-induced protein denaturation.

    Green, Melanie C; Clark, Jenna L

    2013-03-01

    A growing body of research suggests that smoking portrayals in movies influence adolescent tobacco use. However, the mechanism for this influence remains unclear. The aim of this paper is to provide an overview of research on narrative transportation theory, particularly as applied to movies and smoking. We propose that this theory can provide a valuable framework for guiding research on the role of entertainment media in smoking and other addictive behaviors. We review empirical work on transportation theory and highlight the psychological mechanisms underlying transportation effects. 'Transportation into narrative worlds' refers to cognitive, emotional and imagery engagement into a narrative (including movies and entertainment media). We link this work with research on the effects of movie smoking. Research suggests that individuals who are more highly transported into narratives show greater attitude, belief and behavior change. Transportation effects work through reducing counterarguing, creating connections (identification and liking) with characters and increasing perceptions of realism and emotional involvement. We propose several future directions and research challenges for applying a transportation framework to the issue of entertainment media effects on smoking and tobacco disparities. Understanding factors contributing to transportation may provide a more nuanced view of who will be affected by movie smoking, and understanding the psychological processes underlying narrative persuasion may guide intervention efforts. Narrative transportation theory suggests that individuals' cognitive, emotional and imagery immersion in a narrative is a key mechanism of attitude, belief and behavior change. This theory provides a potentially generative and psychologically grounded framework for increasing knowledge about the boundary conditions and processes underlying the effects of entertainment media on tobacco use. © 2012 The Authors, Addiction © 2012 Society for

    Habitual exercising is an important precursor to both physical and psychological well-being. There is, thus, a strong interest in identifying key factors that can best motivate individuals to sustain regular exercise regimen. In addition to the importance of psychographic factors, social media use may act as external motivator by allowing users to interact and communicate about exercise. In this study, we examined the influence of health consciousness, health-oriented beliefs, intrinsic motivation, as willingness to communicate about health on social media, social media activity on exercise, and online social support on exercise maintenance and well-being on a sample of 532 American adults. Employing structural equation modeling, we found that health-oriented beliefs mediated the effect of health consciousness on intrinsic motivation which in turn was a significant predictor of exercise maintenance. Exercise maintenance significantly predicted both physical and psychological well-being. Extrinsic motivators, as measured by willingness to communicate about health on social media, social media activity on exercise, and online social support did not however significantly influence exercise maintenance. These findings have implications for the design and implementation of exercise-promoting interventions by identifying underlying factors that influence exercise maintenance.

    Messages conveyed by media act as a major drive in shaping attitudes and inducing opinion shift. On the other hand, individuals are strongly affected by peer pressure while forming their own judgment. We solve a general model of opinion dynamics where individuals either hold one of two alternative opinions or are undecided and interact pairwise while exposed to an external influence. As media pressure increases, the system moves from pluralism to global consensus; four distinct classes of collective behavior emerge, crucially depending on the outcome of direct interactions among individuals holding opposite opinions. Observed nontrivial behaviors include hysteretic phenomena and resilience of minority opinions. Notably, consensus could be unachievable even when media and microscopic interactions are biased in favor of the same opinion: The unfavored opinion might even gain the support of the majority.

    2008-01-01

    Liquid-liquid extraction of lead(II) from succinate media was carried out with 2-octylaminopyridine (2-OAP) in chloroform. Lead(II) was quantitatively extracted with 0.036 M 2-OAP in chloroform from 0.005-0.007 M sodium succinate when equilibrated for 5 min. Lead(II) from the organic phase was stripped with three 10 mL portions of 0.4 M acetic acid and determined titrimetrically with EDTA. The nature of extracted species was determined from the log-log plot. The optimum conditions have been evaluated based on a critical study of weak acid concentration, extractant concentration, period of equilibration and effect of diluents. The metal loading capacity of the reagent was found to be 8 mg of lead(II) with 10 mL 0.036 M of the extractant. The extraction of the lead(II) was carried out in presence of various ions to ascertain the tolerance limit of individual. Temperature dependence of the extraction equilibrium constants was examined to estimate the apparent thermodynamic functions (ΔH, ΔS and ΔG) for extraction reaction. Lead(II) was successfully separated from commonly associated metal ions such as Bi(III), Hg(II), Cr(VI), Cd(II), Zn(II), Al(III), Ca(II), Ba(II) and from binary and ternary mixtures. The method was extended for determination of lead(II) in real samples

    Full Text Available Starting from the assumption that media is tightly related to the political system of the respective country, we will focus on the aspects that define democracy and determine the profile of the journalist’s role in a democratic system. A good political system has the duty to accomplish two things: to create governments that ensure the well being of the citizens, through a civil society based on legislation and free changes in the market and to protect the citizens against corruption. We will provide a comparative analysis of the roles that journalists play in a democratic society. Our paper deals with the way in which the relation between the media and the political class is perceived in a democracy. This role is often defined by syntagms that focus on the journalists’ rights and not on their responsibilities. Without a clear establishment of the obligations assumed by press professionals, these syntagms allow abuses. This paper will deal with the following aspects: the relation between the media and the political class, the transition of the Romanian media from totalitarianism to democracy, the free market of ideas, and the influence of journalists’ professional culture.

    The current study examined how parental mediation of media (restrictive mediation, active mediation, and coviewing) influenced child outcomes. Three meta-analyses, 1 for each type of mediation, were conducted on a total of 57 studies. Each analysis assessed the effectiveness of parental mediation on 4 pertinent child outcomes: media use, aggression, substance use, and sexual behavior. The overall results indicated small, but significant relationships between child outcomes and restrictive mediation (r+ = -.06), and coviewing (r+ = .09). Overall active mediation was nonsignificant, though active mediation was individually related to lower levels of aggression (r+ = -.08), sexual behavior (r+ = -.06), and substance use (r+ = -.11). This analysis revealed that parents may have the ability to mitigate some of the adverse effects of the media by using certain mediation strategies. Overall, a cooperative effort from the communication and parenting fields is necessary for a comprehensive analysis of parental mediation as well as a disentanglement of the various parental mediation measures.

    Although children's media consumption has been one of the most robust risk factors for childhood obesity, effects of specific parenting influences, such as parental media monitoring, have not been effectively investigated. To examine the potential influences of maternal and paternal monitoring of child media exposure and children's general activities on body mass index (BMI) in middle childhood. A longitudinal study, taken from a subsample of the Three Generational Study, a predominantly white, Pacific Northwest community sample (overall participation rate, 89.6%), included assessments performed from June 1998 to September 2012. Analyses included 112 mothers, 103 fathers, and their 213 children (55.4% girls) at age 5, 7, and/or 9 years. Participation rates ranged from 66.7% to 72.0% of all eligible Three Generational Study children across the 3 assessments. Parents reported on their general monitoring of their children (whereabouts and activities), specific monitoring of child media exposure, children's participation in sports and recreational activities, children's media time (hours per week), annual income, and educational level. Parental BMI was recorded. Predictions to level and change in child BMI z scores were tested. Linear mixed-effects modeling indicated that more maternal, but not paternal, monitoring of child media exposure predicted lower child BMI z scores at age 7 years (95% CI, -0.39 to -0.07) and less steeply increasing child BMI z scores from 5 to 9 years (95% CI, -0.11 to -0.01). These effects held when more general parental monitoring, and parent BMI, annual income, and educational level were controlled for. The significant negative effect of maternal media monitoring on children's BMI z scores at age 7 years was marginally accounted for by the effect of child media time. The maternal media monitoring effect on children's BMI z score slopes remained significant after adjustment for children's media time and sports and recreational activity. These

    Full Text Available Chemical speciation of citric acid complexes of Co(II, Ni(II, Cu(II and Zn(II was investigated pH-metrically in 0.0-2.5% anionic, cationic and neutral micellar media. The primary alkalimetric data were pruned with SCPHD program. The existence of different binary species was established from modeling studies using the computer program MINIQUAD75. Alkalimetric titrations were carried out in different relative concentrations (M:L:X = 1:2:5, 1:3:5, 1:5:3 of metal (M to citric acid. The selection of best chemical models was based on statistical parameters and residual analysis. The species detected were MLH, ML2, ML2H and ML2H2. The trend in variation of stability constants with change in mole fraction of the medium is explained on the basis of electrostatic and non-electrostatic forces. Distributions of the species with pH at different compositions of micellar media are also presented.

  4. Effects of Mass Media and Cultural Drift in a Model for Social Influence

    Science.gov (United States)

    Mazzitello, Karina I.; Candia, Julián; Dossetti, Víctor

    In the context of an extension of Axelrod's model for social influence, we study the interplay and competition between the cultural drift, represented as random perturbations, and mass media, introduced by means of an external homogeneous field. Unlike previous studies [J. C. González-Avella et al., Phys. Rev. E 72, 065102(R) (2005)], the mass media coupling proposed here is capable of affecting the cultural traits of any individual in the society, including those who do not share any features with the external message. A noise-driven transition is found: for large noise rates, both the ordered (culturally polarized) phase and the disordered (culturally fragmented) phase are observed, while, for lower noise rates, the ordered phase prevails. In the former case, the external field is found to induce cultural ordering, a behavior opposite to that reported in previous studies using a different prescription for the mass media interaction. We compare the predictions of this model to statistical data measuring the impact of a mass media vasectomy promotion campaign in Brazil.

    Full Text Available Social media influencers (SMIs can be defined as a new type of independent actor who are able to shape audience attitudes through the use of social media channels in competition and coexistence with professional media. Being able to accurately identify SMIs is critical no matter what is being transmitted in a social system. Social Network Analysis (SNA has been recognized as a powerful tool for representing social network structures and information dissemination. SMIs can be identifi ed by their high-ranking position in a network as the most important or central nodes. The results reveal the existence of three different typologies of SMIs: disseminator, engager and leader. This methodology permits the optimization of resources to create effective online communication strategies.

  6. MHC Class II and Non-MHC Class II Genes Differentially Influence Humoral Immunity to Bacillus anthracis Lethal Factor and Protective Antigen

    Full Text Available Anthrax Lethal Toxin consists of Protective Antigen (PA and Lethal Factor (LF, and current vaccination strategies focus on eliciting antibodies to PA. In human vaccination, the response to PA can vary greatly, and the response is often directed toward non-neutralizing epitopes. Variable vaccine responses have been shown to be due in part to genetic differences in individuals, with both MHC class II and other genes playing roles. Here, we investigated the relative contribution of MHC class II versus non-MHC class II genes in the humoral response to PA and LF immunization using three immunized strains of inbred mice: A/J (H-2k at the MHC class II locus, B6 (H-2b, and B6.H2k (H-2k. IgG antibody titers to LF were controlled primarily by the MHC class II locus, whereas IgG titers to PA were strongly influenced by the non-MHC class II genetic background. Conversely, the humoral fine specificity of reactivity to LF appeared to be controlled primarily through non-MHC class II genes, while the specificity of reactivity to PA was more dependent on MHC class II. Common epitopes, reactive in all strains, occurred in both LF and PA responses. These results demonstrate that MHC class II differentially influences humoral immune responses to LF and PA.

    We investigated the influence of the inhomogeneous coercivities on the media noise in a CoPtCr-SiO 2 granular perpendicular magnetic recording medium via ex situ and in situ magnetic force microscopy (MFM) techniques. The ex situ MFM analyses exhibited that transition zigzags contributed to strong magnetic clusters in noise images, and thus resulted in dominant component of the media noise. According to the in situ MFM measurements, it was suggested that an amount of magnetic grains inside a microscopic area reversed like one magnetic ''particle because of strong inter-grain exchange coupling, and that these microscopic areas showed their local magnetic switching behaviors. A mathematic transformation was used to obtain approximately the magnetization distribution in recording layer. And the individual microscopic areas inside recorded bits were compared quasi-quantitatively with those leading large transition zigzags in magnetization switching behaviors. It was indicated that the inhomogeneous coercivities is one of crucial reasons of the medium noise in the perpendicular magnetic recording

    Full Text Available Orientation: The rapid development of information communication technology (ICT has changed much of contemporary society. ICT’s influence extends to the working context with ramifications not only for employees but also for the entire organisation. Research purpose: The primary purpose of this research was to investigate the behavioural intention of a sample of employees at a traditional higher education institution to make use of social media within the workplace. Motivation for the study: Social media has become a common tool within society for communication and networking purposes. An understanding of the factors that influence behavioural intention to use social media within the workplace can assist the organisation to better manage social media usage within the workplace. Research design, approach and method: The research adopted the positivism paradigm with a quantitative research approach. The data were analysed making use of exploratory factor analysis and multiple regression analysis. A traditional higher education institution was chosen as the research site for the study, relying on a convenience sample (n = 134 and data gathered using the work-related social media scale and behavioural intention to use scale. Main findings: Although most employees make use of social media for problem-solving and communication purposes already in the workplace, organisations should allow their employees to help manage their reputation on social media. Practical and managerial implications: An understanding of the factors that influence behavioural intention to use social media within the workplace can serve as a useful precursor for both employee and organisational-specific interventions. This study has specific relevance to the use of ICT platforms, such as social media, in traditional higher education institutions in South Africa. The study’s results are therefore useful to both employees as end-users and managers as drivers of such interventions

    2013-06-01

    Full Text Available BACKGROUND: Today, sport represents an element of the quality of life as it is often an indicator of a country's civilisational, societal and economic development. The public is mostly interested in elite sport which has effects for both society as well the lives of individuals as the public is not only interested in sports achievements but also in athlete's private lives. The border between the public and private is difficult to establish. The interlinked work of elite athletes and the media often results in misunderstandings as the media intrudes on the private lives of athletes, which in turn impacts both the private and professional lives of athletes. OBJECTIVE: The study's main purpose was to identify the attitude of elite athletes to the media and the influence of the media on the private and professional lives of athletes. The study also evaluated the qualities of an ideal journalist in the eyes of athletes. METHODS: Differences between more and less experienced elite athletes were studied on a sample of 67 Slovenian athletes from team sports. The data were collected through a questionnaire. The findings were further interpreted in line with the opinions of ten leading athletes from individual sports, which were collected through a semi-structured interview. RESULTS: Differences between groups of more and less experienced athletes were detected in answers to the question, "When do athletes decide to cooperate with the media?" and "Have you already been offended by the media?". Elite athletes like to cooperate with the media and usually give information away freely. Similarly, journalists largely understand that athletes desire peace and quiet prior to a competition. Athletes perceive precision and verification of information as the most important qualities of journalists, while they consider some personal qualities and materialistic characteristics as less important. CONCLUSIONS: The study's results show that in the future athletes would

    Graphical abstract: - Highlights: • Semi-interpenetrating hybrid membranes are used for quantitative cadmium(II) recovery. • Optimization of membrane and solutions compositions is performed. • Membranes present increased stability respect to polymer inclusion membranes. • Models for cadmium (II) extraction and transport are proposed. • Excellent selectivity for Cd(II) over Ni(II), Cu(II) and Pb(II) was achieved. - Abstract: Cd(II) transport from 1 mol dm{sup −3} HCl media was investigated across semi-interpenetrating hybrid membranes (SIHMs) that were prepared by mixing an organic matrix composed of ADOGEN{sup ®} 364 as an extracting agent, cellulose triacetate as a polymeric support and nitrophenyloctyl ether as a plasticizer with an organic/inorganic network (silane phase, SP) composed of polydimethylsiloxane and a crosslinking agent. The stripping phase used was a 10{sup −2} mol dm{sup −3} ethanesulfonic acid solution. The effects of tetraorthoethoxysilane, phenyltrimethoxysilane and N′,N′-bis[3-tri(methoxysilyl)propyl]ethylendiamine as crosslinking agents on the transport were studied. H{sub 3}PO{sub 4} was used as an acid catalyst during the SP synthesis and optimized for transport performance. Solid–liquid extraction experiments were performed to determine the model that describe the transport of Cd(II) via ADOGEN{sup ®} 364. The transport was found to be chained-carrier controlled with a percolation threshold of 0.094 mmol g{sup −1}. The selective recovery of Cd(II) was studied with respect to Ni(II), Zn(II), Cu(II), and Pb(II) at a 1:1 molar ratio, and the optimized membrane system was applied for the recovery of Cd(II) from a real sample consisting of a Ni/Cd battery with satisfactory results. Finally, stability experiments were performed using the same membrane for 14 cycles. The results obtained showed that SIHMs had excellent stability and selectivity, with permeabilities comparable to those of PIMs.

    Full Text Available The purpose of the studies was to determine the effects of media containing composts from sewage sludge and potato pulp on the flowering and decorative value of 'Butterfly Yellow with Blotch' parviflorous pansy. In the experiment 14 potting media, including 12 media made of 4 composts, were tested. The percentage of compost mixed with sphagnum peat was 25%, 50% and 75%. The components of particular composts were as follows: I - municipal sewage sludge 70% and straw 30%; II - municipal sewage sludge 70% and sawdust 30%; III - municipal sewage sludge 35%, potato pulp 35% and straw 30%; IV - municipal sewage sludge 35%, potato pulp 35% and sawdust 30%. Two control potting media were used: 1 - sphagnum peat with Osmocote Exact Lo-Start at the dose 5 g×dm-3 and 2 - sphagnum peat with Azofoska at the dose 2.5 g×dm-3. There was no top-dressing during cultivation. The pansies for whose cultivation a slow-release fertiliser was used turned out to have most flowers, but the plants cultivated in compost with peat at the ratio 1:1 had equally abundant flowering. At the generative stage, the pansies in control media were the most decorative and those growing in 25% of compost I, 75% of compost II and 50% of compost III and IV. On the basis of plant valuation scale, quality assessment and the abundance of flowering it was found that the media containing 50% of composts were optimal for pansy cultivation.

    1982-01-01

    In recent years, various contrast media have been developed for use in coronary angiography. These contrast media may be divided into ionic contrast media of high osmolality, those of low osmolality, and nonionic contrast materials. We conducted our own clinical studies with 40 patients. In random succession a standard contrast medium (ionic, of high osmolality) and a new-generation contrast medium (either nonionic or ionic with low osmolality) were injected into the right and left coronary arteries. After each injection we measured the systolic and diastolic blood pressure using a liquid-filled coronary catheter. In addition, the change in the length of the cardiac cycle was registered in terms of the R-R interval (in ms) and at the same time, leads I, II, and III of the ECG were recorded. We studied the influence of the various contrast media on the activity of ATPase in in vitro experiments, using Lasser and Lang's. When ionic contrast media of low osmolality and nonionic contrast media were utilized the heart rate showed no change. Disturbances of rhythm such as ventricular tachycardia or fibrillation were not observed. All of the contrast media used produced the same ECG changes. These changes can be ascribed to the inhibition of ATPase. The arterial blood pressure was lowered significantly only by ionic contrast media of high osmolality only. (orig.)

    Pediatricians care for children's growth and development from the time they are born until they become adults. In addition, pediatricians must be vigilant for external influences. Technology influences children of all ages. Seventy-five percent of teenagers own cell phones, with 25% using them for social media. Technology can lead to an increase in skills and social benefits but there is also the potential for harm such as sexting, cyberbullying, privacy issues, and Internet addiction, all of which can affect health. Pediatricians must become well versed in the new media to provide media-oriented anticipatory guidance and advice on media-related issues. Copyright © 2012 Elsevier Inc. All rights reserved.

    Full Text Available Media relations in sport mean maintenance of networks and positive relationships with people in the media to obtain positive media exposure for a sport product (informal and formal information sessions with media representatives. Because of the pervasive influence the media has on marketing success, sport marketers must make concerted efforts to create a positive relationship between their sport event and the media. They may accomplish this by providing the media with press releases, having news conferences, having media-day events (in which the media are invited to interact with the players, coaches, and administrators, providing media guides for the respective sport events and so on. Each of these activities promotes active involvement from the media, which will subsequently contribute to relationship building with the community.

    Full Text Available This research attempts to examine the political par- ticipation of social media users particularly of Facebook and Twitter during the 2014 Indonesian presidential election. The data collection was per- formed through survey with accidental sampling methods. Samples were taken from population of undergraduate students of political and social sci- ences faculty at five universities in Yogyakarta namely UGM, UIN Sunan Kalijaga, UMY, UNY and UPN “Veteran” Yogyakarta. Using statistic descriptive, this research conceptualizes the political participation of social media users while the relations of social me- dia and political participation is analyzed through OLS Regression. The findings indicated that the level of political participation of the social media users during the election was categorized as good. How- ever, the facilities offered by the two social media applications were not maximally used to supporting political participation activities. On the other hand, the result OLS regression shows that there were positive and significant correlations and influences of social media towards the political participation of its users during the election even though the per- centage was small.

  3. Evolution of the Digital Society Reveals Balance between Viral and Mass Media Influence

    Online social networks (OSNs) enable researchers to study the social universe at a previously unattainable scale. The worldwide impact and the necessity to sustain the rapid growth of OSNs emphasize the importance of unraveling the laws governing their evolution. Empirical results show that, unlike many real-world growing networked systems, OSNs follow an intricate path that includes a dynamical percolation transition. In light of these results, we present a quantitative two-parameter model that reproduces the entire topological evolution of a quasi-isolated OSN with unprecedented precision from the birth of the network. This allows us to precisely gauge the fundamental macroscopic and microscopic mechanisms involved. Our findings suggest that the coupling between the real preexisting underlying social structure, a viral spreading mechanism, and mass media influence govern the evolution of OSNs. The empirical validation of our model, on a macroscopic scale, reveals that virality is 4-5 times stronger than mass media influence and, on a microscopic scale, individuals have a higher subscription probability if invited by weaker social contacts, in agreement with the "strength of weak ties" paradigm.

    This study examined the main and interaction effects of gender, traditional gender role orientation, and media-influenced sociocultural values and ideals about appearance in a sample of 96 Latino adolescents controlling for age, country of origin, and BMI. Girls and less traditionally oriented youth reported significantly more disordered eating and appearance concerns than did boys and more traditionally oriented youth. Gender moderated the relationship between traditional gender role orientation and disordered eating and appearance concerns. Contrary to our hypothesis, media-influenced sociocultural values and ideals about appearance did not significantly predict disordered eating and appearance concerns. However, the interaction between gender and sociocultural values and ideals about appearance was significant. Our findings highlight the importance of continued research on gender, media, and cultural influences as they relate to disordered eating and appearance concerns among Latino youth.

    We examined the influence of phantoms and tube voltage in fluoroscopy on the image intensifier (I.I.) conversion factor. We used 20-cm-thick acrylic resin, 20 mm aluminum, and 1.5 mm copper, which are generally used as phantoms in the measurement of I.I. incident dose rate. We measured I.I. incident dose rate and conversion factor under conditions in which the range of tube voltage was from 60 kV to 120 kV. The result showed that the conversion factor is influenced by the type of phantom, with copper showing the highest value, aluminum second, and acrylic the smallest under the same condition of aluminum at half value layer. It was determined that conversion factor depends on tube voltage and has peaks from 80-100 kV. The location and height of the peak are influenced by the type of phantom. Therefore, I.I. incident dose rate is influenced by both the type of phantom and tube voltage under automatic brightness control fluoroscopy. Unification of phantoms and tube voltage is necessary for long-term evaluation of I.I. incident dose rate. (author)

    An increasing number of women are undergoing labiaplasty procedures; however, very little is known about the psychological factors that motivate women to seek out this procedure. To investigate the factors that influence women's decisions to undergo labiaplasty. Women seeking to undergo labiaplasty (n = 35) were compared with women who were not (n = 30). Standardized measures were employed to assess the patients' media exposure (television, the Internet, advertising, pornography), relationship quality, and psychological well-being. Women's motivations for deciding to undergo a labiaplasty procedure were characterized as "appearance," "functional," "sexual," or "psychological" motivations, with concerns about the labia's appearance being the most commonly reported motivation. Correspondingly, women seeking labiaplasty were significantly less satisfied with the appearance of their genitals than the comparison group (P media exposure and relationship status as important factors that influence women's decisions to undergo labiaplasty. 3 Risk. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

    Stability of recorded magnetization of hard disk drive (HDD) is influenced by external environments, such as temperature and magnetic field. Small scratches are frequently formed on HDD medium surface upon contacts with the magnetic head. The influences of temperature and mechanical scratch on the magnetization structure stability are investigated for longitudinal and perpendicular recording media by using a magnetic force microscope. PMR media remained almost unchanged up to about 300 deg. C for the area with no scratches, whereas the areas near and under mechanical scratches started to change around 250 deg. C. The magnetization structure of LMR media started to change at about 100 degrees lower temperature under mechanical scratches when compared with no scratch areas. A quantitative analysis of magnetization structure variation is carried out by measuring the recorded magnetization strength difference estimated from the MFM images observed for a same sample area before and after exposing the sample to different temperatures.

    Popular media have played a crucial role in the construction, representation, reproduction, and transmission of stereotypes of science, technology, engineering, and mathematics (STEM) professionals, yet little is known about how these stereotypes influence STEM identity formation. Media images of STEM professionals may be important sources of information about STEM and may be particularly salient and relevant for girls during adolescence as they actively consider future personal and professional identities. This article describes gender-stereotyped media images of STEM professionals and examines theories to identify variables that explain the potential influence of these images on STEM identity formation. Understanding these variables is important for expanding current conceptual frameworks of science/STEM identity to better determine how and when cues in the broader sociocultural context may affect adolescent girls’ STEM identity. This article emphasizes the importance of focusing on STEM identity relevant variables and STEM identity status to explain individual differences in STEM identity formation. PMID:28603505

    During outbreaks of infectious diseases with high morbidity and mortality, individuals closely follow media reports of the outbreak. Many will attempt to minimize contacts with other individuals in order to protect themselves from infection and possibly death. This process is called social distancing. Social distancing strategies include restricting socializing and travel, and using barrier protections. We use modeling to show that for short-term outbreaks, social distancing can have a large influence on reducing outbreak morbidity and mortality. In particular, public health agencies working together with the media can significantly reduce the severity of an outbreak by providing timely accounts of new infections and deaths. Our models show that the most effective strategy to reduce infections is to provide this information as early as possible, though providing it well into the course of the outbreak can still have a significant effect. However, our models for long-term outbreaks indicate that reporting historic infection data can result in more infections than with no reporting at all. We examine three types of media influence and we illustrate the media influence with a simulated outbreak of a generic emerging infectious disease in a small city. Social distancing can never be complete; however, for a spectrum of outbreaks, we show that leaving isolation (stopping applying social distancing measures) for up to 4 hours each day has modest effect on the overall morbidity and mortality.

    Highlights: ► We fabricated a composite electrospun nanofiber as a selective sorbent for lead (II) in PFSPE. ► The composite nanofiber was functionalized with the dithizone by co-electrospinning of the PS solution containing unbonded dithizone. ► The nanofiber was characterized by scanning electron microscope and IR spectra. ► We applied the nanofiber by packing in a cartridge. ► The nanofiber performed well in the absorption of lead (II) and was applied successfully in aqueous samples. - Abstract: An electrospun nanofiber was utilized as a sorbent in packed fiber solid phase extraction (PFSPE) for selective separation and preconcentration of lead (II). The nanofiber had a polystyrene (PS) backbone, which was functionalized with dithizone (DZ) by co-electrospinning of a PS solution containing DZ. The nanofiber exhibited its performance in a cartridge prepared by packing 5 mg of nanofiber. The nanofiber was characterized by a scanning electron microscope and IR spectra. The diameter of the nanofiber was less than 400 nm. After being activated by 2.0 mol L −1 NaOH aqueous solution, the nanofiber quantitatively sorbed lead (II) at pH 8.5, and the metal ion could be desorbed from it by three times of elution with a small volume of 0.1 mol L −1 HNO 3 aqueous solution. The breakthrough capacity was 16 μg mg −1 . The nanofiber could be used for concentration of lead (II) from water and other aqueous media, such as plasma with stable recovery in a simple and convenient manner.

    Understanding the family dynamic surrounding media use is crucial to our understanding of media effects, policy development, and the targeting of individuals and families for interventions to benefit child health and development. The Families, Parenting, and Media Workgroup reviewed the relevant research from the past few decades. We find that child characteristics, the parent-child relationship, parental mediation practices, and parents' own use of media all can influence children's media use, their attitudes regarding media, and the effects of media on children. However, gaps remain. First, more research is needed on best practices of parental mediation for both traditional and new media. Ideally, this research will involve large-scale, longitudinal studies that manage children from infancy to adulthood. Second, we need to better understand the relationship between parent media use and child media use and specifically how media may interfere with or strengthen parent-child relationships. Finally, longitudinal research on how developmental processes and individual child characteristics influence the intersection between media and family life is needed. The majority of children's media use takes place within a wider family dynamic. An understanding of this dynamic is crucial to understanding child media use as a whole.

    The degree to which media contributes to body dissatisfaction, life satisfaction and eating disorder symptoms in teenage girls continues to be debated. The current study examines television, social media and peer competition influences on body dissatisfaction, eating disorder symptoms and life satisfaction in a sample of 237 mostly Hispanic girls. 101 of these girls were reassessed in a later 6-month follow-up. Neither television exposure to thin ideal media nor social media predicted negative outcomes either concurrently nor prospectively with the exception of a small concurrent correlation between social media use and life satisfaction. Social media use was found to contribute to later peer competition in prospective analysis, however, suggesting potential indirect but not direct effects on body related outcomes. Peer competition proved to be a moderate strong predictor of negative outcomes both concurrently and prospectively. It is concluded that the negative influences of social comparison are focused on peers rather than television or social media exposure.

    Natural aquifers typically exhibit a variety of structural heterogeneities. However, the effect of mineral colloids and natural organic matter on the transport behavior of uranium (U) in saturated heterogeneous media are not totally understood. In this study, heterogeneous column experiments were conducted, and the constructed columns contained a fast-flow domain (FFD) and a slow-flow domain (SFD). The effect of kaolinite, humic acid (HA), and kaolinite/HA mixture on U(VI) retention and release in saturated heterogeneous media was examined. Media heterogeneity significantly influenced U fate and transport behavior in saturated subsurface environment. The presence of kaolinite, HA, and kaolinite/HA enhanced the mobility of U in heterogeneous media, and the mobility of U was the highest in the presence of kaolinite/HA and the lowest in the presence of kaolinite. In the presence of kaolinite, there was no difference in the amount of U released from the FFD and SFD. However, in the presence of HA and kaolinite/HA, a higher amount of U was released from the FFD. The findings in this study showed that medium structure and mineral colloids, as well as natural organic matter in the aqueous phase had significant effects on U transport and fate in subsurface environment.

Removal of heavy metal ions such as Fe(III, Cd(II, Zn(II, Cu(II, Mn(II, Mg(II, and Pb(II from water and wastewater is obligatory in order to avoid water pollution. Batch shaking adsorption experiments to evaluate the performance of nitric and hydrochloric acid solutions in the removal of metal ions by cation exchange resin at the same conditions for both, such as the effect of initial metal ion concentration, different proportions of some organic solvents, H+-ion concentrations and reaction temperature on the partition coefficients. The metal adsorption for the cation exchanger was found to be significant in different media for both nitric and hydrochloric acids, i.e., the adsorption up take of metal ions presented in this work is very significant depending on the characteristics of ions and on the external concentrations of solute. The presence of low ionic strength or low concentration of acids does have a significant adsorption of metal ions on ion-exchange resin. The results show that the ion exchanger could be employed for the preconcentration, separation and the determination.

    Stability of recorded magnetization of hard disk drives (HDDs) is influenced by external environments, such as temperature, magnetic field, etc. Small scratches are frequently formed on HDD medium surface upon contacts with the magnetic head. Influence of temperature and mechanical scratch on the magnetization structure stability of perpendicular recording media was investigated by using a magnetic force microscope. The magnetic bit shape started to change at around 300 0 C for an area with no scratches, whereas for the area near a shallow mechanical scratch it started to change at a lower temperature around 250 0 C. An analysis of magnetization structure under an influence of temperature and mechanical scratch is carried out for the magnetization structure variation and recorded magnetization strength.

    Full Text Available Rutin (quercetin-3-O-rutinoside is one of the most abundant bioflavonoids with various biological and pharmacological activities. Considering the ubiquitous presence of Mg(II and Ca(II ions in biological systems we decided to investigate their influence on the autoxidation of rutin in weakly alkaline aqueous solutions. Changes in UV-Vis spectra recorded during the rutin autoxidation in aqueous solution at pH 8.4 revealed that this process was very slow in the absence of metal ions. The presence of Mg(II and, especially Ca(II ion, increased the transformation rate of rutin. UV-Vis spectra recorded after prolonged autoxidation indicated the formation of humic acidlike products in the presence of Mg(II and Ca(II ions. Four new compounds formed during the initial stage of rutin autoxidation in the presence of Mg(II and Ca(II ions were detected by HPLCDAD. Based on the analysis of their DAD UV-Vis spectra and comparison of their retention times with the retention time value for rutin, we concluded that the initial rutin transformation products were formed by the water addition on double bond in ring C and hydroxylation of ring B. A very small decrease of the initial rutin concentration (4% was observed by HPLC-DAD in the absence of metal ions for the period of 90 minutes. However, rutin concentration decrease was much larger in the presence of Mg(II and Ca(II ions (14% and 24%, respectively. The more pronounced effect of Ca(II ion on the rutin autoxidation may be explained by the stronger binding of Mg(II ion to rutin and thus greater stabilizing effect on reaction intermediates caused by its higher ionic potential (charge/ionic radius ratio in comparison to Ca(II ion. The results of this study may contribute to the better understanding of interactions of Mg(II and Ca(II ions with natural phenolic antioxidants which are important for their various biological activities.

    Most organizations have an existing policy for interactions with the media. This policy often requires that interactions be with or through a professional group of public information officers or the Office of Public Affairs. This policy tends to give individual members of an organization the belief that they are not responsible or in some instances, even allowed to interact with the media. To achieve good media relationships and/or coverage, individual interactions are necessary and required. The guidelines for media interactions provided in the Federal Emergency Management Agency (FEMA) sponsored Radiological Emergency Response course are relatively straightforward and simple to adopt

    Full Text Available The gangue filter media was modified by the titanium dioxide (TiO2 through the liquid phase deposition method. Some influence factors of photocatalytic activity were investigated, including the mole ratio of initial solution, the water bath temperature, the deposition time, the calcination temperature, and the heat preservation time of calcination. The morphology of the film was examined by SEM, EDS, and crystallite structure by X-Ray Diffraction (XRD. The SEM, EDS, and XRD data showed that new TiO2 crystal was found in the modified filter media. And the specific surface area of the modified filter media greatly increased. By the orthogonal experiment, the optimum parameters of modification were (NH42TiF6:H3BO3=1:2, water bath temperature of 80ºC, deposition time of 5h, calcination temperature of 500ºC, and 1h heat preservation time of calcination. Under above conditions, the heavy nitrogen wastewater of 1589.94 mg/L COD and 18750 times chroma was treated by the modified filter media. After 1h catalytic reaction, the decolorization rate and COD removal rate reached 65.89% and 47.87%, respectively.

    Childhood maltreatment is associated with many maladaptive outcomes. This study sought to examine the association between childhood maltreatment and problematic social media use using a cross-sectional sample of young adults aged 17-25 years (n = 1029). Specifically, we studied whether the relationship is mediated through (i) attachment anxiety, (ii) attachment avoidance, or (iii) both attachment dimensions operating in series with depressive symptoms. Results revealed that a history of childhood maltreatment was significantly associated with more problematic social media use. Both anxious and avoidant attachment dimensions independently mediated the relationship between childhood maltreatment and problematic use of social media, but in opposing directions. Avoidant attachment was associated with less problematic social media use, whilst anxious attachment was associated with more problematic social media use. Avoidant attachment and depressive symptoms in series accounted for part of the relationship between childhood maltreatment and problematic social media use. Anxious attachment and depressive symptoms in series fully mediated the relationship between childhood maltreatment and problematic social media use. The results suggest that childhood maltreatment may influence social media use directly, but also indirectly. People experiencing depressive symptoms may overuse social media in an attempt to alleviate their distress. However, causality cannot be established with the current design. Copyright © 2018.

    The rapid development of new media has exacerbated the complexity of urban street space’s information interaction. With the influence of the immersion communication, the streetscape has constructed a special scene like ‘media convergence’, which has brought a huge challenge for maintaining the urban streetscape order. The Spatial Visual Communication Research Method which should break the limitation of the traditional aesthetic space research, can provide a brand new prospect for this phenomenon research. This study aims to analyze and summarize the communication characteristics of new media and its context, which will be helpful for understanding the social meaning within the order change of the street’s spatial and physical environment.

    Full Text Available The paper investigates new phraseological units in political journalism of online media, which are characterized by fused writing of words that make up the phraseme. It is assumed that this kind arose under the influence of hashtags in which, as a rule, some words are written without spaces. Phraseological innovations of this kind are part of the language game in journalism of online media, as they currently are not so typical for printed newspapers. The main purpose of using neophraseme with fused writing of words is to increase the text expressiveness and emotionality.

  16. Does media coverage influence public attitudes towards welfare recipients? The impact of the 2011 English riots.

    Reeves, Aaron; de Vries, Robert

    2016-06-01

    Following the shooting of Mark Duggan by police on 4 August 2011, there were riots in many large cities in the UK. As the rioting was widely perceived to be perpetrated by the urban poor, links were quickly made with Britain's welfare policies. In this paper, we examine whether the riots, and the subsequent media coverage, influenced attitudes toward welfare recipients. Using the British Social Attitudes survey, we use multivariate difference-in-differences regression models to compare attitudes toward welfare recipients among those interviewed before (pre-intervention: i.e. prior to 6 August) and after (post-intervention: 10 August-10 September) the riots occurred (N = 3,311). We use variation in exposure to the media coverage to test theories of media persuasion in the context of attitudes toward welfare recipients. Before the riots, there were no significant differences between newspaper readers and non-readers in their attitudes towards welfare recipients. However, after the riots, attitudes diverged. Newspaper readers became more likely than non-readers to believe that those on welfare did not really deserve help, that the unemployed could find a job if they wanted to and that those on the dole were being dishonest in claiming benefits. Although the divergence was clearest between right-leaning newspaper and non-newspaper readers, we do not a find statistically significant difference between right- and left-leaning newspapers. These results suggest that media coverage of the riots influenced attitudes towards welfare recipients; specifically, newspaper coverage of the riots increased the likelihood that readers of the print media expressed negative attitudes towards welfare recipients when compared with the rest of the population. © London School of Economics and Political Science 2016.

    2017-01-01

    Media's presentation of eating is an important source of influence on viewers' eating goals and behaviors. Drawing on recent research indicating that whether a story character continues to pursue a goal or completes a goal can unconsciously influence an audience member's goals, a scene from a popular movie comedy was manipulated to end with a character continuing to eat (goal ongoing) or completed eating (goal completed). Participants (N = 147) were randomly assigned to a goal status condition. As a reward, after viewing the movie clip viewers were offered two types of snacks: ChexMix and M&M's, in various size portions. Viewers ate more food after watching the characters continue to eat compared to watching the characters complete eating, but only among those manipulated to identify with a character. Viewers were more likely to choose savory food after viewing the ongoing eating scenes, but sweet dessert-like food after viewing the completed eating scenes. The results extend the notion of media influence on unconscious goal contagion and satiation to movie eating, and raise the possibility that completing a goal can activate a logically subsequent goal. Implications for understanding media influence on eating and other health behaviors are discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Reducing the extent and persuasive power of marketing unhealthy foods to children worldwide are important obesity prevention goals. Research is limited to understand how brand mascots and cartoon media characters influence children's diet. We conducted a systematic review of five electronic databases (2000–2014) to identify experimental studies that measured how food companies' mascots and entertainment companies' media characters influence up to 12 diet-related cognitive, behavioural and health outcomes for children under 12 years. Eleven studies met the inclusion criteria. Studies used 21 unique popular media characters, but no brand mascots. Results suggest that cartoon media character branding can positively increase children's fruit or vegetable intake compared with no character branding. However, familiar media character branding is a more powerful influence on children's food preferences, choices and intake, especially for energy-dense and nutrient-poor foods (e.g. cookies, candy or chocolate) compared with fruits or vegetables. Future research should use a theoretically grounded conceptual model and larger and more diverse samples across settings to produce stronger findings for mediating and moderating factors. Future research can be used to inform the deliberations of policymakers, practitioners and advocates regarding how media character marketing should be used to support healthy food environments for children.

    Over the past two decades, men who have sex with men (MSM) have engaged in increasing consumption of MSM-specific sexually explicit online media (i.e., online pornography). Furthermore, the amount of MSM-specific sexually explicit online media portraying unprotected anal intercourse (UAI) has increased, raising concerns about HIV transmission among the actors and the potential encouragement of risky sex among consumers. The influence of sexually explicit online media on sexual risk-taking, at present largely understudied, could lead to new avenues for innovative HIV-prevention strategies targeting at-risk MSM. In this preliminary assessment, in-depth qualitative interviews were conducted with 16 MSM in the Seattle area to elucidate MSM's perceptions about the influence of sexually explicit online media on their own and other MSM's sexual behaviors. Participants reported that sexually explicit online media: (1) plays an educational role, (2) increases comfort with sexuality, and (3) sets expectations about sexual behaviors. While participants overwhelmingly reported not feeling personally influenced by viewing UAI in sexually explicit online media, they believed viewing UAI increased sexual risk-taking among other MSM. Specifically, participants reported that the high prevalence of UAI in sexually explicit online media sends the message, at least to other MSM, that (1) engaging in UAI is common, (2) UAI is acceptable and "ok" to engage in, and (3) future partners will desire or expect UAI. Overall, this preliminary assessment indicates that sexually explicit online media exposure may have both positive (e.g., helping MSM become more comfortable with their sexuality) and negative (e.g., normalizing UAI) impacts on the sexual health of MSM and may be useful in the development of novel HIV-prevention interventions.

  2. Influence of gas law on ultrasonic behaviour of porous media under pressure.

    Griffiths, S; Ayrault, C

    2010-06-01

    This paper deals with the influence of gas law on ultrasonic behaviour of porous media when the saturating fluid is high pressured. Previous works have demonstrated that ultrasonic transmission through a porous sample with variations of the static pressure (up to 18 bars) of the saturating fluid allows the characterization of high damping materials. In these studies, the perfect gas law was used to link static pressure and density, which is disputable for high pressures. This paper compares the effects of real and perfect gas laws on modeled transmission coefficient for porous foams at these pressures. Direct simulations and a mechanical parameters estimation from minimization show that results are very similar in both cases. The real gas law is thus not necessary to describe the acoustic behaviour of porous media at low ultrasonic frequencies (100 kHz) up to 20 bars. 2010 Elsevier B.V. All rights reserved.

    To examine the association of adolescents' wanting to look like figures in the media with physical activity levels. Cross-sectional mailed survey of 11,606 boys and girls, between the ages of 9 and 16 years, participating in the Growing Up Today Study in 1997. Participants reported detailed information on physical activities over the previous year, and the degree to which they were trying to look like same-sex images in television, movies, and magazines. We performed linear regression modeling to assess the independent effects of wanting to look like figures in the media on physical activity levels. Mean total weekly physical activity levels were 12.4 hours in girls and 15.2 hours in boys. 3019 (46%) girls and 1360 (27%) boys reported making at least some effort to look like figures in the media. Adjusted for age, body mass index, sexual maturity rating, and race/ethnicity, total physical activity levels were higher by 0.7 (95% CI 0.5-0.9) and 1.2 (95% CI 0.9-1.6) hours per week in girls and boys, respectively, for every 1 (out of 5) category increase in wanting to look like figures in the media. Adjustment for intrapersonal and social confounders modestly attenuated the associations. Wanting to look like figures in the media was associated with higher physical activity levels among older children and adolescents, independent of other personal and social influences. These data suggest that television, movie, and magazine industries should be encouraged to cultivate and reinforce realistic and healthy norms of physical activity and body image.

    Whether the type of culture media utilized in assisted reproductive technology has impacts on laboratory outcomes and birth weight of newborns in in-vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) was investigated. A total of 673 patients undergoing IVF/ICSI and giving birth to live singletons after fresh embryo transfer on day 3 from Jan. 1, 2010 to Dec. 31, 2012 were included. Three types of culture media were used during this period: Quinn's Advantage (QA), Single Step Medium (SSM), and Continuous Single Culture medium (CSC). Fertilization rate (FR), normal fertilization rate (NFR), cleavage rate (CR), normal cleavage rate (NCR), good-quality embryo rate (GQER) and neonatal birth weight were compared using one-way ANOVA and χ (2) tests. Multiple linear regression analysis was performed to determine the impact of culture media on laboratory outcomes and birth weight. In IVF cycles, GQER was significantly decreased in SSM medium group as compared with QA or CSC media groups (63.6% vs. 69.0% in QA; vs. 71.3% in CSC, P=0.011). In ICSI cycles, FR, NFR and CR were significantly lower in CSC medium group than in other two media groups. No significant difference was observed in neonatal birthweight among the three groups (P=0.759). Multiple linear regression analyses confirmed that the type of culture medium was correlated with FR, NFR, CR and GQER, but not with neonatal birth weight. The type of culture media had potential influences on laboratory outcomes but did not exhibit an impact on the birth weight of singletons in ART.

    Dagmar Podmaková

    2015-10-01

    Full Text Available The paper poses questions concerning the extent of direct or indirect impact of new media on the concept of a theatrical production and on the perception of a concret theatrical performance. Using examples of theatrical preoductions, the author divided the impact of media into several areas. One of them is the insertion of film clips into a theatrical performance or simultaneous large screen projections of what is happening on stage. The second area concerns (indirect effect of new media on the currentness of the testimony of theatre-makers, such as, for instance, the projection of TV news that accentuate the impact of everydayness on the aesthetic perception of an audience. One should not discount the side effects of the media that entered the theatre, such as the effect of TV series on the social media popularity of actors. Therefore, when actors perform on stage, the audiences are inclined to perceive them as TV-series characters rather than dramatic characters.

    Full Text Available The existence of heavy metal ions in aqueous media is one of the biggest environmental pollution problems and thus the removal of heavy metals is a very important procedure. In this work, a new adsorbent was synthesized by modifying 3-aminopropyl-functionalized silica gel with thiamine (vitamin B1 and characterized. The influence of the uptake conditions, such as pH, contact time, initial feed concentration and foreign metal ions, on the binding capacity of thiamine-functionalized silica gel sorbent (M3APS were investigated. Maximum obtained adsorption capacities for Pb(II, Hg(II and Cd(II were 39.4±0.2, 30.9±0.5 and 9.54±0.4 mg g-1 M3APS, respectively, at pH 5.0. The observed selectivity of M3APS for these metal ions was the following: Pb(II > Hg(II > Cd(II. Adsorption isotherm models were also applied to the adsorption process. As a result, the Langmuir isotherm model gave the best fit for the adsorption of metal ions on M3APS. The Gibbs energy change (ΔG for the adsorption of Pb(II, Hg(II and Cd(II were calculated to predict the nature of adsorption process. Having such satisfactory adsorption results, M3APS is a potential candidate adsorbent for Pb(II and Hg(II removal from aqueous media.

  10. Influence of welded boundaries in anelastic media on energy flow, and characteristics of P, S-I, and S-II waves: Observational evidence for inhomogeneous body waves in low-loss solids

    A general computer code, developed to calculate anelastic reflection-refraction coefficients, energy flow, and the physical characteristics for general P, S-I, and S-II waves, quantitatively describes physical characteristics for wave fields in anelastic media that do not exist in elastic media. Consideration of wave fields incident on boundaries between anelastic media shows that scattered wave fields experience reductions in phase and energy speeds, increases in maximum attenuation and Q-1, and directions of maximum energy flow distinct from phase propagation. Each of these changes in physical characteristics are shown to vary with angle of incidence. Finite relaxation times for anelastic media result in energy flow due to interaction of superimposed radiation fields and contribute to energy flow across anelastic boundaries for all angles of incidence. Agreement of theoretical and numerical results with laboratory measurements argues for the validity of the theoretical and numerical formulations incorporating inhomogeneous wave fields. The agreement attests to the applicability of the model and helps confirm the existence of inhomogeneous body waves and their associated set of distinct physical characteristics in the earth. The existence of such body waves in layered, low-loss anelastic solids implies the need to reformulate some seismological models of the earth. The exact anelastic formulation for a liquid-solid interface with no low-loss approximations predicts the existence of a range of angles of incidence or an anelastic Rayleigh window, through which significant amounts of energy are transmitted across the boundary. The window accounts for the discrepancy apparent between measured reflection data presented in early textbooks and predictions based on classical elasticity theory. Characteristics of the anelastic Rayleigh window are expected to be evident in certain sets of wide-angle, ocean-bottom reflection data and to be useful in estimating Q-1 for some

    Full Text Available Chemically and thermally treated rice husks were evaluated as a potential decontaminant of toxic Cd (II in aqueous media. Rice husk (RH, a by-product from rice milling, was chemically treated with HCl and NaOH. Then, thermal treatments to 300, 500, and 700°C were applied. The chemical composition and morphological characteristics of RH were evaluated by different techniques. The specific surface area analysis of RH samples by BET nitrogen adsorption method provided specific surface areas ranging from 6 to 14 m2/g. SEM, FTIR, and EDX analyses of RH were carried out to determine the surface morphology, functional groups involved in metal binding mechanism, and C/O and C/Si ratios, respectively. The maximum Cd (II adsorption capacity was 28.27 mg/g at an optimum pH, 6.0. The kinetic studies revealed that adsorption process followed the pseudo-second-order kinetic model.

    Full Text Available A notion, according to which editorials have a bigger communication influence than advertisements, is very common and quite popular in public relations. The said notion is so prevalent (among both public relations and marketing communications experts that it has led to the concept of perceived influence multipliers that point to a stronger editorial influence in comparison to advertising influence (2.5 to 8 times stronger. Based on the described assumption, the aim of this paper was to further explore how the target audience perceives editorial and advertising content. The research problem was to compare the effects of both types of content on behavior and behavioral intent (through four media – Internet, radio, newspapers and television. Respondents were divided into two groups – current users of the service that was in focus (for influence on behavior and potential users (for influence on behavioral intent. Even though current users said that editorials had a bigger influence on their behavior, this difference was not significant. On the other hand, potential users stated that the advertising content shaped their behavioral intent more than did editorials. These results once again show the assumption, according to which editorials have a stronger communication influence than advertisements, to be highly questionable.

    Spheroids of mesenchymal stem cells (MSCs) in cartilage tissue engineering have been shown to enhance regenerative potential owing to their 3D structure. In this study, we explored the possibility of priming spheroids under different media to replace the use of inductive surface coatings for chondrogenic differentiation. Rat bone marrow-derived MSCs were organized into cell spheroids by the hanging drop technique and subsequently cultured on hyaluronic acid (HA) coated or non-coated well plates under different cell media conditions. Endpoint analysis included cell viability, DNA and Glycosaminoglycan (GAG) and collagen content, gene expression and immunohistochemistry. For chondrogenic applications, MSC spheroids derived on non-coated surfaces outperformed the spheroids derived from HA-coated surfaces in matrix synthesis and collagen II gene expression. Spheroids on non-coated surfaces gave rise to the highest collagen and GAG when primed with medium containing insulin-like growth factor (IGF) for 1 week during spheroid formation. Spheroids that were grown in chondroinductive raw material-inclusive media such as aggrecan or chondroitin sulfate exhibited the highest Collagen II gene expression in the non-coated surface at 1 week. Media priming by growth factors and raw materials might be a more predictive influencer of chondrogenesis compared to inductive-surfaces. Such tailored bioactivity of the stem cell spheroids in the stage of the spheroid formation may give rise to a platform technology that may eventually produce spheroids capable of chondrogenesis achieved by mere media manipulation, skipping the need for additional culture on a modified surface, that paves the way for cost-effective technologies.

    Waqas Ejaz

    2017-05-01

    Full Text Available This paper posits that the concept of European identity is an important indicator of the legitimacy of the European Union (EU. It further assumes that the exposure to EU related media content can influence the feeling of European identity. In order to verify this assumption, we combined the mere-exposure-theory and the hostile media phenomenon. We assume that these theoretical concepts could help to understand the influence of media on people’s levels of attachment to the EU. Regression analyses are performed on secondary data that were collected in a Eurobarometer survey in 2013. Our findings revealed that media exposure affected the respondents’ identification with Europe, as well as the modifications of this effect based on their assessments of EU media coverage. The results of the current study not only validate assumptions about the mere-exposure effects on identity but also confirm the theoretical assumption that perceived hostility reduces such effects, whereas exposure to information that is perceived as neutral promotes the effects of media exposure on the feeling of European identity.

    Within the medical community there is persistent debate as to whether the information available through social media is trustworthy and valid, and whether physicians are ready to adopt these technologies and ultimately embrace them as a format for professional development and lifelong learning. To identify how physicians are using social media to share and exchange medical information with other physicians, and to identify the factors that influence physicians' use of social media as a component of their lifelong learning and continuing professional development. We developed a survey instrument based on the Technology Acceptance Model, hypothesizing that technology usage is best predicted by a physician's attitudes toward the technology, perceptions about the technology's usefulness and ease of use, and individual factors such as personal innovativeness. The survey was distributed via email to a random sample of 1695 practicing oncologists and primary care physicians in the United States in March 2011. Responses from 485 physicians were analyzed (response rate 28.61%). Overall, 117 of 485 (24.1%) of respondents used social media daily or many times daily to scan or explore medical information, whereas 69 of 485 (14.2%) contributed new information via social media on a daily basis. On a weekly basis or more, 296 of 485 (61.0%) scanned and 223 of 485 (46.0%) contributed. In terms of attitudes toward the use of social media, 279 of 485 respondents (57.5%) perceived social media to be beneficial, engaging, and a good way to get current, high-quality information. In terms of usefulness, 281 of 485 (57.9%) of respondents stated that social media enabled them to care for patients more effectively, and 291 of 485 (60.0%) stated it improved the quality of patient care they delivered. The main factors influencing a physician's usage of social media to share medical knowledge with other physicians were perceived ease of use and usefulness. Respondents who had positive

    Biological media affect the physicochemical properties of cationic lipid-DNA complexes (lipoplexes) and can influence their ability to transfect cells. To develop new lipids for efficient DNA delivery, the influence of serum-containing media on the structures and properties of the resulting lipoplexes must be understood. To date, however, a clear and general picture of how serum-containing media influences the structures of lipoplexes has not been established. Some studies suggest that serum can disintegrate lipoplexes formed using certain types of cationic lipids, resulting in the inhibition of transfection. Other studies have demonstrated that lipoplexes formulated from other lipids are stable in the presence of serum and are able to transfect cells efficiently. In this article, we describe the influence of serum-containing media on lipoplexes formed using the redox-active cationic lipid bis(n-ferrocenylundecyl)dimethylammonium bromide (BFDMA). This lipoplex system promotes markedly decreased levels of transgene expression in COS-7 cells as serum concentrations are increased from 0 to 2, 5, 10, and 50% (v/v). To understand the cause of this decrease in transfection efficiency, we used cryogenic transmission electron microscopy (cryo-TEM) and measurements of zeta potential to characterize lipoplexes in cell culture media supplemented with 0, 2, 5, 10, and 50% serum. Cryo-TEM revealed that in serum-free media BFDMA lipoplexes form onionlike, multilamellar nanostructures. However, the presence of serum in the media caused disassociation of the intact multilamellar lipoplexes. At low serum concentrations (2 and 5%), DNA threads appeared to separate from the complex, leaving the nanostructure of the lipoplexes disrupted. At higher serum concentration (10%), disassociation increased and bundles of multilamellae were discharged from the main multilamellar complex. In contrast, lipoplexes characterized in serum-free aqueous salt (Li(2)SO(4)) medium and in OptiMEM cell

    While governments and academic institutions urge researchers to engage with news media, traditional academic values of public disengagement have inhibited many from giving high priority to media activity. In this interview-based study, the authors report on the views about news media engagement and strategies used by 36 peer-voted leading Australian public health researchers in 6 fields. The authors consider their views about the role and importance of media in influencing policy, their reflections on effective or ineffective media communicators, and strategies used by these researchers about how to best retain their credibility and influence while engaging with the news media. A willingness and capacity to engage with the mass media was seen as an essential attribute of influential public health researchers.

    Full Text Available To explore the influence of complexity of reservoir properties in porous media and the diversity of operating conditions on the steam distillation rate of crude oil in the process of heavy oil exploitation with steam injection, steam distillation simulation devices are used to study steam distillation rate of crude oil in porous media. Then steam distillation ratio is obtained under the condition of different core permeability, oil saturation, steam temperatures, system pressure, steam injection rates and steam distillation rates with different viscosities of crude oil. The results show that the steam distillation rate of crude oil in porous media depends mainly on the nature of the crude oil itself, for temperature and pressure are the key factors compared with the pore structure, the initial oil saturation and steam injection rate. The experimental results help estimate the amount of crude oil and the required steam in the reservoir in the steam drive process, aiming to facilitate the optimization design and operation of steam drive.

    Full Text Available Background: The problems associated with unsafe sexual behavior in adolescents are caused by premarital sexual intercourse with a partner of their own age. One of the problems caused by premarital sex is a pregnancy outside of marriage. Increased incidence of premarital sex is caused by the development through media depictions of sex scenes in the form of television, magazines, video clips, online media, and films. In Musi Banyuasin there are 7754 high school students, many students have dropped out of school because they get pregnant before marriage so that in adolescence their parents are forced to marry or have abortions. The aim study is determined the factors associated with unsafe sexual behavior in adolescents in high school. Method: Observational research with cross sectional and quantitative approach. The population is high school students. Sampling technique was using multistage random sampling obtained 393 samples. Bivariate analysis, chi-square Result: the result showed a correlation between the influence of peers with adolescent sexual behavior has p-value (0,000. There was no relationship between media pornography with sexual behavior because the result more than p-value (0,05. Conclusion: Necessary to be given knowledge and assistance to adolescents about positively and creatively thing and supervision of parents to their children in order to have a friends and avoid unsafe sexual behavior.   Key words: The Influence of Peers, Pornographic Media, Unsafe Sexual, Adolescent

    This paper examines the ways rural businesses can become attractive to millennials using the Internet and the social media. It has become evident that the prominent way to reach out to millennials is via social media accounts. Rural businesses need to use the personal relationships they develop with their customers and expand these relationships on social media. It is also apparent that traditional marketing fails to apply to small rural businesses, whereas influencer marketing becomes a valu...

    2015-12-01

    Perivascular cells are multilineage cells located around the vessel wall and important for wall stabilization. In this study, we evaluated a stem cell media and a perivascular cell-specific media for the culture of primary perivascular cells regarding their cell morphology, doubling time, stem cell properties, and expression of cell type-specific markers. When the two cell culture media were compared to each other, perivascular cells cultured in the stem cell medium had a more elongated morphology and a faster doubling rate and cells cultured in the pericyte medium had a more typical morphology, with several filopodia, and a slower doubling rate. To evaluate stem cell properties, perivascular cells, CD146(-) cells, and mesenchymal stem cells (MSCs) were differentiated into the adipogenic, osteogenic, and chondrogenic lineages. It was seen that perivascular cells, as well as CD146(-) cells and MSCs, cultured in stem cell medium showed greater differentiation than cells cultured in pericyte-specific medium. The expression of pericyte-specific markers CD146, neural/glial antigen 2 (NG2), platelet-derived growth factor receptor-β (PDGFR-β), myosin, and α-smooth muscle actin (α-SMA) could be found in both pericyte cultures, as well as to varying amounts in CD146(-) cells, MSCs, and endothelial cells. The here presented work shows that perivascular cells can adapt to their in vitro environment and cell culture conditions influence cell functionality, such as doubling rate or differentiation behavior. Pericyte-specific markers were shown to be expressed also from cells other than perivascular cells. We can further conclude that CD146(+) perivascular cells are inhomogeneous cell population probably containing stem cell subpopulations, which are located perivascular around capillaries. © 2015 International Federation for Cell Biology.

    2018-03-01

    The role of nonfictional and fictional media in suicide contagion has been well established, ostensibly beginning with the publication of Goethe's The Sorrows of Young Werther in 1774. In recent decades, the emergence of several new forms of media (e.g. websites, social media, blogs, smartphone applications) has revolutionized the communication and social interaction paradigms. This article reviews "the Werther effect" (or suicide contagion related to media), special populations who are more influential or susceptible, current media reporting guidelines and their effectiveness, and the latest research on new media and its effect on suicide and suicide contagion. The aim is to update recommendations on how to mitigate the potential negative effects of both traditional and new media on suicidal behavior and suicide contagion.

    2011-12-01

    Full Text Available Just like the celebrities, social movement depends, to an extent, on media in communicating its activities to the public. The relationship between social movement and media is transactional. On the one hand, social movement needs media to disseminate its activities. On the other hand, media needs social movement as the news source. Scant (beyond very few notable exceptions empirical research is not available on boycott product as a social movement and stakeholder analysis in Indonesia. The objective of this study is to perform stakeholder analysis on boycott product as a social movement. To do so, the study attempts to answer some questions: (i what are the trigger and root cause of boycott movement?; (ii what are the interest and influence of each stakeholder on boycott movement?; (iii how is the existing relationship among stakeholders?; and (iv among the stakeholders, which group does get priority? The news about boycott was collected from national media. The news was then analyzed by content analysis. The results show that in the case of boycott, many parties are involved. However, firms’ management has to give priority to consumers, special interest groups, and the gov-ernment. Attention can be manifested in a continuous and sustainable dialogue with them.

    Full Text Available More and more employers declare they used or plan to use social media throughout human resources management processes. On one side, it is part of employer branding policy to offer relevant information to people about how it is to work in that organisation, including social media channels. On the other side, these means are really attractive regarding targeting options and reaching a wide range of applicants at a low cost. This paper summarizes the main evolutions of social media use in businesses in general, but also in recruitment, in particular. Moreover, we consider the ethical implications and possible solutions.

    Kotler, Jennifer A; Schiffman, Jennifer M; Hanson, Katherine G

    2012-01-01

    Two experiments were conducted to assess the role of media characters in influencing children's food choices; the first focused on children's self-reported preference, whereas the second focused on actual choice. The results of the experiments suggest that popular characters can make a difference in encouraging children to select one food over another. In the first experiment, children were more likely to indicate a preference for one food over another when one was associated with characters that they liked and with whom they were familiar. This effect was particularly strong when a sugary or salty snack branded by a favored character was competing with a healthier option branded by an unknown character or no character. Alternatively, when children were asked to choose between a healthy food and a sugary or salty snack, branding of the healthy food with a favored character did not significantly change appeal of that healthy snack. However, when foods within the same category (i.e., 2 vegetables, 2 fruits, or 2 grains) were asked to compete against each other, character branding strongly influenced children's food choice. Findings from the second experiment suggest that children are more willing to try more pieces of a healthy food if a favored character, in comparison with an unknown character, is promoting that food.

    Full Text Available In many cases of unwanted behaviour that we analysed (for instance in case of cheating on school tests, beating, being bullied, conflicts with parents, gambling, intentionally damaging or destroying property we found a statistically significant effect of the extent of digital media use on incidence of such behaviour. Youth, who are large digital media users, behave in such socially unwanted ways more often compared to smaller media users. A dominant share of youth isn’t involved in violent behaviour or vandalism at all. However, the incidence of violence or vandalism in the large media users group is significantly higher compared to low and medium users group.

    Social media and electronic news media activity are an important source of information for the general public. Yet, there is a dearth of research exploring the use of Twitter and electronic news outlets during significant worldly events such as the recent Ebola Virus scare. The purpose of this article is to investigate the use of Twitter and electronic news media outlets in communicating Ebola Virus information. A cross-sectional survey of Twitter data and Google News Trend data from 30 September till 29 October, 2014 was conducted. Between 30 September and 29 October, there were approximately 26 million tweets (25,925,152) that contained the word Ebola. The highest number of correlated activity for Twitter and electronic news outlets occurred on 16 October 2014. Other important peaks in Twitter data occurred on 1 October, 6 October, 8 October, and 12 October, 2014. The main influencers of the Twitter feeds were news media outlets. The study reveals a relationship between electronic news media publishing and Twitter activity around significant events such as Ebola. Healthcare organizations should take advantage of the relationship between electronic news media and trending events on social media sites such as Twitter and should work on developing social media campaigns in co-operation with leading electronic news media outlets (e.g. CNN, Yahoo, Reuters) that can have an influence on social media activity. © The Author(s) 2015.

    For children of school age television is still the dominant medium. TV consumption isn't only limited on the TV set, but also happens on the computer with internet access and mobile devices. Computer games take a high priority for boys. For girls reading is still an important experience space. Parents influence the media use of their children by their role model, and the rates for shared non-media experiences. Neighborhoods which aren't child-friendly can cause children's withdraw into home media spaces. Restrictions and controls are less important than the conversations that are conducted around media interests of the child and parents attention to early signs of problematic media use. Potentially irritating media content for children (such as violence or sex) can have strong effects when there's no open debate taking place in the family around these issues. Today's media diversity leads to parallel surfing and multi-tasking. In order that this doesn't influence children's cognitive development and learning negatively a culture of regular restriction to one activity, to which they devote their full attention, is required.

    2016-09-01

    Theoretical investigations predicting the epidemic curves of seasonal influenza have been demonstrated so far; however, there is little empirical research using ever accumulated epidemic curves. The effects of vaccine coverage and information distribution on influenza epidemics were evaluated. Four indices for epidemics (i.e., onset-peak duration, onset-end duration, ratio of the onset-peak duration to onset-end duration and steepness of epidemic curves) were defined, and the correlations between these indices and anti-flu drug prescription dose, vaccine coverage, the volume of media and search trend on influenza through internet were analyzed. Epidemiological data on seasonal influenza epidemics from 2002/2003 to 2013/2014 excluding 2009/2010 season were collected from National Institute of Infectious Diseases of Japan. The onset-peak duration and its ratio to onset-end duration correlated inversely with the volume of anti-flu drug prescription. Onset-peak duration correlated positively with media information volume on influenza. The steepness of the epidemic curve, and anti-flu drug prescription dose inversely correlated with the volume of media information. Pre-epidemic search trend and media volume on influenza correlated with the vaccine coverage in the season. Vaccine coverage had no strong effect on epidemic curve. Education through media has an effect on the epidemic curve of seasonal influenza. Copyright © 2016 The Author(s). Published by Elsevier Ltd.. All rights reserved.

    2017-01-01

    The rising use of digital media in the last decade, including social networking media and downloadable applications, has created new opportunities for marketing a wide range of goods and services, including alcohol products. This paper aims to review the evidence in order to answer a series of policy-relevant questions: does alcohol marketing through digital media influence drinking behaviour or increases consumption; what methods of promotional marketing are used, and to what extent; and what is the evidence of marketing code violations and especially of marketing to children? A search of scientific, medical and social journals and authoritative grey literature identified 47 relevant papers (including 14 grey literature documents). The evidence indicated (i) that exposure to marketing through digital media was associated with higher levels of drinking behaviour; (ii) that the marketing activities make use of materials and approaches that are attractive to young people and encourage interactive engagement with branded messaging; and (iii) there is evidence that current alcohol marketing codes are being undermined by alcohol producers using digital media. There is evidence to support public health interventions to restrict the commercial promotion of alcohol in digital media, especially measures to protect children and youth. © 2016 Society for the Study of Addiction.

    2017-03-01

    As an important public health issue, patient medication non-adherence has drawn much attention, but research on the impact of mass media as an information source on patient medication adherence has been scant. Given that mass media often provide confusing and contradicting information regarding health/medical issues, this study examined the potential negative influence of exposure to health information in mass media on patients' beliefs about their illnesses and medications, and medication adherence, in comparison with the effects of exposure to another primary medication information source, physicians. Survey data obtained from patients on blood thinner regimens revealed that the frequency of exposure to health information in mass media was negatively related to accuracy of patients' beliefs about their medication benefits and patient medication adherence. On the other hand, frequency of visits with physicians was positively associated with patients' beliefs about their medication benefits but had no significant relation to medication regimen adherence. The implications of the study findings are discussed, and methodological limitations and suggestion for future research are presented.

    Full Text Available Introduction Increased serum level of low density lipoprotein (LDL cholesterol is a well established risk factor for atherosclerosis development and progression. Genetic variation in the LDL receptor gene could modulate serum LDL level and response to statin treatment thus affecting atherosclerosis development and progression. The present study was designed to investigate the association between polymorphism AvaII (rs5925 of the LDL receptor gene with serum lipid levels and carotid intima-media thickness (CIMT in patients with diabetes mellitus type 2 (DM2.Methods 595 patients with DM2 (399 on statin therapy and 196 without were enrolled in the study. The carotid intima-media thickness was assessed ultrasonographically. Biochemical analyses were performed using standard biochemical methods. AvaII (rs5925 genotypes were determined by real-time PCR. Results Genotype distribution and allele frequencies were not statistically significantly different between DM2 patients with regard to statin therapy. In DM2 patients using statins the highest serum levels of total and LDL cholesterol were observed in homozygous carriers of the A+ allele. After adjustment for well established cardiovascular risk factors homozygosity for the A+ allele (β=0.441 and p=0.04, statin treatment as well as serum levels of HDL, triglycerides, hsCRP and fibrinogen were independently associated with CIMT. Interactions of AvaII genotypes A-A+ and A+A+ with statin treatment were not statistically significant.Conclusion Homozigosity for the A+ allele of the AvaII polymorphism is associated with greater CIMT in DM2 patients.

    2018-02-21

    The current generation of adolescents grows up in a media-saturated world. However, it is unclear how media influences the maturational trajectories of brain regions involved in social interactions. Here we review the neural development in adolescence and show how neuroscience can provide a deeper understanding of developmental sensitivities related to adolescents' media use. We argue that adolescents are highly sensitive to acceptance and rejection through social media, and that their heightened emotional sensitivity and protracted development of reflective processing and cognitive control may make them specifically reactive to emotion-arousing media. This review illustrates how neuroscience may help understand the mutual influence of media and peers on adolescents' well-being and opinion formation.

    This study examines the influence of mass media, interpersonal communication, and elaborative processing on public perception of benefits and risks of nanotechnology, based on a large-scale nationally representative telephone survey of U.S. adult citizens. Results indicate that cognitive processes in the form of news elaboration had a significant positive main effect on benefits outweigh risks perception. The influences of attention to science in newspapers, attention to science news on television, and interpersonal communication about science on public perception of benefits outweigh risks were moderated by elaborative processing, after controlling for socio-demographic variables, religious beliefs, trust in scientists, and scientific knowledge. The findings highlight the importance of elaborative processing when it comes to understanding how the mass media differentially influence public benefits outweigh risks perception of emerging technologies. Specifically, high elaborative processing emphasizes higher levels of perceived benefits outweigh risks than low elaborative processing. This study explores explanations for this phenomenon and offers implications for future research and policy.

  1. Major factors influencing the generation of natural gas hydrate in porous media

    Directory of Open Access Journals (Sweden)

    2017-11-01

    Full Text Available Current researches related to natural gas hydrate mainly focus on its physical and chemical properties, as well as the approaches to the production (decomposition of hydrate. Physical modeling of the flow process in hydrate deposits is critical to the study on the exploitation or decomposition of hydrate. However, investigation of the dynamic hydrate process by virtue of porous media like sand-packed tubes which are widely used in petroleum production research is rarely reported in literature. In this paper, physical simulation of methane hydrate generation process was conducted using river sand-packed tubes in the core displacement apparatus. During the simulation, the influences of parameters such as reservoir temperature, methane pressure and reservoir model properties on the process of hydrate generation were investigated. The following results are revealed. First, the use of ice-melted water as the immobile water in the reservoir model can significantly enhance the rate of methane hydrate generation. Second, the process driving force in porous media (i.e., extents to which the experimental pressure or temperature deviating those corresponding to the hydrate phase equilibrium plays a key role in the generation of methane hydrate. Third, the induction period of methane hydrate generation almost does not change with temperature or pressure when the methane pressure is above 1.4 folds of the hydrate phase equilibrium pressure or the laboratory temperature is lower than the phase equilibrium temperature by 3 °C or more. Fourth, the parameters such as permeability, water saturation and wettability don't have much influence on the generation of methane hydrate.

  2. Media work as public affairs: moving beyond media savvy

    Trapp, Leila; Laursen, Bo

    Much research exists which examines how politically-motivated organizations adapt their communication practices to suit the news media’s routines and values to gain media coverage and thereby exert political influence. The mediatization literature describes these adaptation processes as constantly...... evolving, with professional communicators exhibiting an ever-growing amount of media savvy. The purpose of this study is to gain up-to-date insights into current forms of media adaptation in political organizations through interviews with professional press contact staff in 52 Danish interest groups....... The interviews reveal that media work is considered an effective, though potentially risky, form of public affairs. Indeed, media work is said to damage, or even ruin, an organization’s lobbying efforts or relationships with political actors. The study’s key finding is that in order to deal with these risks...

    2017-12-01

    Mass media have numerous effects on children, ranging from influencing school performance to increased or reduced aggression. What we do not know, however, is how media availability in the bedroom moderates these effects. Although several researchers have suggested that bedroom media may influence outcomes by displacing other activities (the displacement hypothesis) or by changing the content of media consumed (the content hypothesis), these have rarely been tested directly. This study tested both hypotheses using several outcomes that are associated with bedroom media and some of the underlying mediating mechanisms. The hypotheses were tested using 3 longitudinal samples of varying methods, age, duration, and country. The results indicate that children who have bedroom media are likely to watch larger amounts of screen time which displaced important activities, such as reading and sleeping, which mediated later negative outcomes such as poor school performance. Bedroom media also influence risk for obesity and video game addiction. Children with bedroom media are also likely to be exposed to more media violence. The violent content increased normative beliefs about aggression, which increased physical aggression, providing support for the content hypothesis. This study demonstrates that media can have effects not just from what they show, but also because of what children are not exposed to. Bedroom media are therefore a robust risk factor for several aspects of child development. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    2014-01-01

    This study examined disordered eating, socio-cultural media influencers, body image, and psychological factors among a large, racially/ethnically diverse sample of college women (n=1445; 58% White, 21% Asian, 11% Hispanic, 11% Black) who completed an online survey. Black women were significantly more satisfied with their weight and shape and had lower eating concerns, disinhibited eating, and emotional eating than all other racial/ethnic groups. Black women tended to have significantly higher levels of self-esteem, were less likely to compare their body to those of people in the media, felt less pressured to attain the physical appearance standard set by the media, and had less awareness of the societal appearance norms set by the media than other racial groups. Findings suggest that Black college women, independent of weight status, may be protected from disordered eating, negative body image, and societal media pressures. © 2013.

    Social media and mobile phones have emerged as important platforms for college students' communication activities. This study examined how college students' psychological need to belong is associated with their use of social media and smartphones. In addition, it further investigated the effects of college students' digital media use on their social engagement. Findings revealed that students' need to belong was positively related with their use of social media and smartphones, which could further facilitate their social engagement. Moreover, the relationship between the need to belong and social engagement was mediated by college students' digital media use. This study offers empirical evidence of the positive effects of digital media on social behaviors and contributed to further understanding about the mechanisms by which need to belong leads to social engagement through digital media use.

    To compare embryo quality, fertilization, implantation, miscarriage and clinical pregnancy rates for embryos cultured in two different commercial culture media until D-2 or D-3. In this retrospective study, we analyzed 189 cycles performed in 2016. Metaphase II oocytes were microinjected and allocated into single medium (SAGE 1-STEP, Origio) until transferred, frozen or discarded; or, if sequential media were used, the oocytes were cultured in G1-PLUSTM (Vitrolife) up to D-2 or D-3 and in G2-PLUSTM (Vitrolife) to transfer. On the following day, the oocytes were checked for normal fertilization and on D-2 and D-3 for morphological classification. Statistical analysis was performed using the chi-square and Mann-Whitney tests in PASW Statistics 18.0. The fertilization rates were 70.07% for single and 69.11% for sequential media (p=0.736). The mean number of embryos with high morphological quality (class A/B) was higher in the single medium than in the sequential media: D-2 [class A (190 vs. 107, pcultured in single medium were frozen: 197 (21.00%) vs. sequential: 102 (11.00%), pculture in single medium yields greater efficiency per cycle than in sequential media. Higher embryo quality and quantity were achieved, resulting in more frozen embryos. There were no differences in clinical pregnancy rates.

    The relative impact of genetic and social influences on disordered eating behaviors (DEB) including binging, purging, excessive dieting and negative self-evaluations about weight remain an issue of debate. The current study sought to examine the relative influence of genetic and social influences on DEB. A 7-year prospective analysis of 580 monozygotic (MZ) and dizygotic (DZ) twins was conducted. Estimates of heritability of DEB were obtained using the DF Analysis Model. Regression equations revealed the relative predictive value of sibling's DEB, neurotic personality, maternal warmth and television and video game exposure on DEB. Heritability estimates for DEB were 0.40 for females and 0.48 for males. Among MZ and DZ twin pairs, female sex, neurotic personality and a genetic variable component, but not maternal warmth or school related problems, predicted DEB. Contrary to the expectations of media effects theory, greater media use was associated with lower DEB among DZ twins and had no influence on MZ twins. These results indicate that DEB is highly heritable and that personality variables may play an important role in the formation of DEB. This suggests that it is important to control for genetic variables when analyzing risk factors for DEB.

  1. Solute transport in aggregated and layered porous media

    Koch, S.

    1993-01-01

    This work is a contribution to research in soil physics dealing with solute transport in porous media. The influence of structural inhomogeneities on solute transport is investigated. Detailed experiments at the laboratory scale are used to enlighten distinct processes which cannot be studied separately at field scale. Two main aspects are followed up: (i) to show the influence of aggregation of a porous medium on breakthrough time and spreading of an inert tracer and consequences on the estimation of parameter values of models describing solute transport in aggregated systems, (ii) to investigate the influences on the dispersion process when stratification is perpendicular to the direction of flow. Several concepts of modelling solute transport in soil are discussed. Models based on the convection-dispersion equation (CDE) are emphasized because they are used here to model solute transport experiments conducted with aggregated porous media. Stochastic concepts are introduced to show the limitations of the deterministic CDE approaches. Experiments are done in columns containing two kinds of solid phases and were saturated with water. The solid phases are porous and solid glass beads exhibiting a distinctly unimodal or bimodal pore size distribution. Experimental breakthrough curves (BTCs) are modelled with the CDE, a bicontinuum model with a phenomenological mass transfer rate and a bicontinuum spherical diffusion model. Experiments are also done in columns that are unsaturated containing porous materials that are layered. Flow is made at a steady rate. It is shown that layer boundaries have a severe influence on lateral mixing. They may force streamlines to converge or cause a lateral redistribution of solutes. (author) figs., tabs., 122 refs

    Mesenchymal stem cells (MSCs) are known to interact with cancer cells through direct cell-to-cell contact and secretion of paracrine factors, although their exact influence on tumor progression in vivo remains unclear. To better understand how fetal and adult stem cells affect tumors, we analyzed viability of human renal (786-0) and bladder (T24) carcinoma cell lines cultured in conditioned media harvested from amniotic fluid-derived stem cells (AFSCs) and adipose-derived stem cells (ASCs). Both media reduced metabolic activity of 786-0 cells, however, decreased viability of T24 cells was noted only after incubation with conditioned medium from ASCs. To test the hypothesis that MSCs-secreted factors might be involved in chemoresistance acquisition, we further analyzed influence of mesenchymal stem cell conditioned media (MSC-CM) on cancer cells sensitivity to ciprofloxacin, that is considered as potential candidate agent for urinary tract cancers treatment. Significantly increased resistance to tested drug indicates that MSCs may protect cancer cells from chemotherapy. J. Cell.

    Adjuvant chemotherapy for stage II colon cancer is a controversial practice and is not recommended by the French Consensus Conference outside of therapeutic trial. To assess, within a well-defined population, the influence of hospital characteristics in this practice. In the Rhône-Alpes region (10% of the French population), 534 patients presenting with colon cancer stage II were operated on in 81 hospitals in the year 2000. The influence of hospital characteristics on the use of adjuvant chemotherapy was assessed using a multivariate logistic regression. Overall, 19.5% of patients received adjuvant chemotherapy. Younger age, T4 tumour, hospital volume lower than 20 colon cancer surgeries [odds ratio (OR) 2.96; Pclinical complications at diagnosis were independently associated with higher rates of chemotherapy. On the other hand, a number of examined lymph nodes lower than recommendations did not have any influence on chemotherapy use. Hospital characteristics had independently influenced the practice of adjuvant chemotherapy in stage II colon cancer. The more important institutional factor was the hospital procedure volume. The decisions of the multidisciplinary committees appeared at times paradoxical; a more comprehensive evaluation of this practice is needed.

    In the marketing model of Solomon and Weisbuch, people buy a product only if their neighbours tell them of its quality, and if this quality is higher than their own quality expectations. Now we introduce additional information from the mass media, which is analogous to the ghost field in percolation theory. The mass media shift the percolative phase transition observed in the model, and decrease the time after which the stationary state is reached.

  12. Cosplaying the media mix: Examining Japan's media environment, its static forms, and its influence on cosplay

    Directory of Open Access Journals (Sweden)

    Matthew Ogonoski

    2014-06-01

    Full Text Available Cosplay—costume role-play—has dramatically increased in popularity over the past 20 years in conjunction with the cultural institution of anime, comic book, manga, science fiction, and other related fandom conventions. Cosplay was prominently established in Japan before gaining attention in North America. In this article I analyze the significance of those Japanese origins in relation to the experience of a unique media environment. The aesthetics and practices of cosplay in Japan are fundamentally informed by a specific ontological characteristic of Japanese anime, manga, and ancillary forms: the static image. Of essential importance to these consumption practices—both materially and conceptually—is the phenomenon of the anime database: an archive of static images that is continually accessed for the purposes of understanding, consuming, and creating new media. Through a detailed discussion of Hiroki Azuma's conception of the moe database, Thomas Lamarre's discussion of the cel bank as a material requisite of the database, and Marc Steinberg's assessment of the media mix, I extend the phenomenological affects of this media environment and its static images to the act of cosplay posing—an act that aspires to create a mimetic and collective connection between cosplayers and particular media images. This exploratory platform will permit me to develop specific conceptions of Japan's complex media environment and its transformations of material forms into ephemeral consumption practices.

    Full Text Available The role and importance of the media are huge, both in everyday life and in cultural, spiritual and political life of modern man. Their power in the sense of political shaping of people and shaping of public opinion is very distinctive. In the process of propaganda to influence public opinion, they use various manipulative procedures in order to accomplish certain interests and objectives. Through the media, politics realizes its economic, ideological, political and even military activities. The war in the former Yugoslavia and former Bosnia and Herzegovina was also waged through the media. This media war still is spreading the hate speech, thus still causing conflicts and disintegration processes in the Balkans.

    Full Text Available This paper aims to identify and analyze the extent to which new media have penetrated the Romanian organizations’ internal communication and have influenced the leadership. We intend also to consider how social media becomes a tool for organizational communication and contributes to the creation of a new kind of leadership associated with open communication. We start from the premise that new media and social media can contribute to the leader’s mission to create around him a vision and makes others to share this vision. In terms of open communication, the external image of organization reflects, in part, leadership practices within the organization. It is about the exercise of the shared collective leadership (Don Tapscott, 1996 that should strengthen the organization position.

Given this widespread influence, it is important for educators, administrators, and technologists to understand the risks of using social media in the classroom and workplace. To investigate popular social media sites and their effect on radiologic technology education and business practices. A comprehensive search of literature was performed to examine social media and its applications in education, health care, and business. Social media use is on the rise, affecting all aspects of mainstream society. Leaders in the radiologic sciences should be familiar with social media and cognizant of its risks. Future studies regarding social media use in the radiologic sciences are necessary to determine its effect on the radiologic science community. ©2011 by the American Society of Radiologic Technologists.

    Full Text Available Background: The person suffering mental disorders is not only burdened by his condition but also by the stigma. The impact of stigma extremely influences society that it is considered to be the obstacle in mental disorders therapy. Stigma as the society adverse view toward severe mental disorders is related with the cultural aspect. The interaction appeared from each component of nursing model namely sunrise model, which a model developed by Madeleine Leininger is connected with the wide society views about severe mental disorders condition in society. Objective: The aim of this study was to analyze the factors related to public stigma and to find out the dominant factors related to public stigma about severe mental illness through sunrise model approach in Sukonolo Village, Malang Regency. Methods: This study using observational analytical design with cross sectional approach. There were 150 respondents contributed in this study. The respondents were obtained using purposive sampling technique. Results: The results showed a significant relationship between mass media exposure, spiritual well-being, interpersonal contact, attitude, and knowledge with public stigma about mental illness. The result from multiple logistic regression shows the low exposure of mass media has the highest OR value at 26.744. Conclusion: There were significant correlation between mass media exposure, spiritual well-being, interpersonal contact, attitude, and knowledge with public stigma toward mental illness. Mass media exposure as a dominant factor influencing public stigma toward mental illness.

  19. Media reporting of risk information: Uncertainties and the future

    This paper argues that very little is known with a reasonable degree of certainty about how the media influence their audiences. Media effects are mediated through diverse, subtle social interactions and processes. Future changes in the regulatory and technological media environment will create even more uncertainty by changing basic parameters of media/audience interaction. More research is needed to help shed light on these uncertainties and future changes. If this research is to be of relevance to real communicators of real risk, it must fully address the issues of how the media are influenced, not just media impacts. In this context, the role of experts, PR, advertising, and media professionals' motivations are key priorities. (orig.)

    2014-05-27

    The inner dynamics of the multiple actors of the informations systems - i.e, T.V., newspapers, blogs, social network platforms, - play a fundamental role on the evolution of the public opinion. Coherently with the recent history of the information system (from few main stream media to the massive diffusion of socio-technical system), in this work we investigate how main stream media signed interaction might shape the opinion space. In particular we focus on how different size (in the number of media) and interaction patterns of the information system may affect collective debates and thus the opinions' distribution. We introduce a sophisticated computational model of opinion dynamics which accounts for the coexistence of media and gossip as separated mechanisms and for their feedback loops. The model accounts also for the effect of the media communication patterns by considering both the simple case where each medium mimics the behavior of the most successful one (to maximize the audience) and the case where there is polarization and thus competition among media memes. We show that plurality and competition within information sources lead to stable configurations where several and distant cultures coexist.

    1985-11-01

    It has been shown that the thermochromic conversions of cobalt(II) in binary solvents are influenced by a number of factors: the nature of the solvent, the strength of the complexes of octahedral symmetry formed, the outer-sphere influence of the solvent on the complexes, the form of the anion, the solvation of the participants in the reaction, and the interaction of the components of the solvent with one another. A correlation between the strength and the spectral position of the absorption bands of the complexes of the activator has been established, and a spectroscopic criterion for selecting the solvents has been proposed. The expediency of using binary solvents to create effective thermochromic media with variable phototransmission has been substantiated.

    Social media platforms are special places of information exposure because they are structured around a user’s social network and not around content, like other news media. Studies could show that news exposure on social media can affect citizens’ political participation due to the personalized......, targeted, & inadvertent exposure. However, previous research did not strongly focus on how the characteristics of a citizens’ social media network might alter this relationship. We tests how political information exposure via three different media channels affects political participation among Danish...... citizens and examine possible moderation effects of users network size, network diversity and the newly introduced parameter of perceived network activity. To this end, a two-wave online survey (n=858) among the Danish population was conducted, applying a smartphone-based media diary study. We find strong...

    Full Text Available Abstract Background Media representations play a crucial role in informing public and policy opinions about the causes of, and solutions to, ill-health. This paper reviews studies analysing media coverage of non-communicable disease (NCD debates, focusing on how the industries marketing commodities that increase NCD risk are represented. Methods A scoping review identified 61 studies providing information on media representations of NCD risks, NCD policies and tobacco, alcohol, processed food and soft drinks industries. The data were narratively synthesized to describe the sample, media depictions of industries, and corporate and public health attempts to frame the media debates. Results The findings indicate that: (i the limited research that has been undertaken is dominated by a focus on tobacco; (ii comparative research across industries/risk-factors is particularly lacking; and (iii coverage tends to be dominated by two contrasting frames and focuses either on individual responsibilities (‘market justice’ frames, often promoted by commercial stakeholders or on the need for population-level interventions (‘social justice’ frames, frequently advanced by public health advocates. Conclusions Establishing the underlying frameworks is crucial for the analysis of media representation of corporations, as they reflect the strategies that respective actors use to influence public health debates and decision making. The potential utility of media research lies in the insights that it can provide for public health policy advocates about successful framing of public health messages and strategies to counter frames that undermine public health goals. A better understanding of current media debates is of paramount importance to improving global health.

  16. Autofluorescence imaging of macular pigment: influence and correction of ocular media opacities

    The healthy adult human retina contains in its macular region a high concentration of blue-light absorbing carotenoid compounds, known as macular pigment (MP). Consisting of the carotenoids lutein, zeaxanthin, and meso-zeaxanthin, the MP is thought to shield the vulnerable tissue layers in the retina from light-induced damage through its function as an optical attenuator and to protect the tissue cells within its immediate vicinity through its function as a potent antioxidant. Autofluorescence imaging (AFI) is emerging as a viable optical method for MP screening of large subject populations, for tracking of MP changes over time, and for monitoring MP uptake in response to dietary supplementation. To investigate the influence of ocular media opacities on AFI-based MP measurements, in particular, the influence of lens cataracts, we conducted a clinical trial with a large subject population (93 subjects) measured before and after cataract surgery. General AFI image contrast, retinal blood vessel contrast, and presurgery lens opacity scores [Lens Opacities Classification System III (LOCS III)] were investigated as potential predictors for image degradation. These clinical results show that lens cataracts can severely degrade the achievable pixel contrasts in the AFI images, which results in nominal MP optical density levels that are artifactually reduced. While LOCS III scores and blood vessel contrast are found to be only a weak predictor for this effect, a strong correlation exists between the reduction factor and the image contrast, which can be quantified via pixel intensity histogram parameters. Choosing the base width of the histogram, the presence or absence of ocular media opacities can be determined and, if needed, the nominal MP levels can be corrected with factors depending on the strength of the opacity.

    The effects of benzimidazole (BIM) and 2-methylbenzimidazole (MBIM) on the electroreduction of Cu(II) on a rotating Pt disk electrode in chloride media were investigated. These studies were undertaken in conjunction with earlier observation that these imidazole derivatives act as inhibitors of copper corrosion processes and are non-toxic. We have found that BIM and MBIM also form adsorption films on Pt, which are able to inhibit one-electron reduction of Cu(II) to Cu(I) and prevent the development of convective diffusion limiting current wave. The inhibition was found to be controlled by field-assisted mass transfer in the film. The ingress of Cu(II) species into the film was detected using the EQCN technique. The EQCN measurements indicate that small fraction of Cu(I) formed in the film by reduction of Cu(II) is retained in the film, most likely in the form of CuCl. The uptake of CuCl by inhibitor films diminishes in strongly inhibiting films (e.g., in acidic medium). The inhibition effectiveness of Cu(II) reduction process by Pt vertical bar BIM and Pt vertical bar MBIM films increases strongly with increasing acidity of the medium in the pH range from 3.0 to 1.0. The mechanism of this remarkable pH effect has been proposed. It is based on charge and pH-induced film restructuring, including changes in orientation and protonation of BIM molecules in the film.

The development of media relation in the current time also shows a higher scientific human existence. And, the side effect of those advances is the ultimate culture turbulence across developing countries. The sophisticated information communication technology at the present time has been victimizing young generation particularly in under developed countries. The power of media is a matter of fact which showing the domination influence of advance nations. In the other hand, the local culture of the victimized countries though still exists, but ultimately is the overwhelmed market of the media goal itself.

    Parkinson disease (PD) is a common neurodegenerative disorder characterized by the presence of Lewy bodies and a reduction in the number of dopaminergic neurons in the substantia nigra of the basal ganglia. Common symptoms of PD include a reduction in control of voluntary movements, rigidity, and tremors. Such symptoms are marked by a severe deterioration in motor function. The causes of PD in many cases are unknown. PD has been found to be prominent in several notable people, including Adolf Hitler, the Chancellor of Germany and Führer of Nazi Germany during World War II. It is believed that Adolf Hitler suffered from idiopathic PD throughout his life. However, the effect of PD on Adolf Hitler's decision making during World War II is largely unknown. Here we examine the potential role of PD in shaping Hitler's personality and influencing his decision-making. We purport that Germany's defeat in World War II was influenced by Hitler's questionable and risky decision-making and his inhumane and callous personality, both of which were likely affected by his condition. Likewise his paranoid disorder marked by intense anti-Semitic beliefs influenced his treatment of Jews and other non-Germanic peoples. We also suggest that the condition played an important role in his eventual political decline. Copyright © 2015 Elsevier Inc. All rights reserved.

  2. Blood and Bones: The Influence of the Mass Media on Australian Primary School Children's Understandings of Genes and DNA

    Donovan, Jenny; Venville, Grady

    2014-02-01

    Previous research showed that primary school children held several misconceptions about genetics of concern for their future lives. Included were beliefs that genes and DNA are separate substances, with genes causing family resemblance and DNA identifying suspects at crime scenes. Responses to this work `blamed' the mass media for these misunderstandings. This study aimed to determine whether that blame had any foundation by examining the media habits and conceptions about genes and DNA of Australian children. With little prior research considering the influence of entertainment mass media on children's academically relevant knowledge, this was an exploratory study with a mixed modes design. Data were collected by detailed media questionnaires and face-to-face interviews with 62 children aged 10-12 years, and subjected to content and thematic analysis. Specific mass media examples children reported using were examined for genetics content. Results indicate 5 h/day of media use, mostly television including crime shows, and that children perceived television to be their main source of information about genetics. Most children (89 %) knew DNA, 60 % knew genes, and more was known about uses of DNA outside the body such as crime solving or resolving family relationships than about its biological nature and function. Half believed DNA is only in blood and body parts used for forensics. These concepts paralleled the themes emerging from the media examples. The results indicate that the mass media is a pervasive teacher of children, and that fundamental concepts could be introduced earlier in schools to establish scientific concepts before misconceptions arise.

    Given the increasing variety of manufactured nanomaterials, suitable, robust, standardized in vitro screening methods are needed to study the mechanisms by which they can interact with biological systems. The in vitro evaluation of interactions of nanoparticles (NPs) with living cells is challenging due to the complex behaviour of NPs, which may involve dissolution, aggregation, sedimentation and formation of a protein corona. These variable parameters have an influence on the surface properties and the stability of NPs in the biological environment and therefore also on the interaction of NPs with cells. We present here a study using 30 nm and 80 nm fluorescently-labelled silicon dioxide NPs (Rubipy-SiO2 NPs) to evaluate the NPs dispersion behaviour up to 48 hours in two different cellular media either supplemented with 10% of serum or in serum-free conditions. Size-dependent differences in dispersion behaviour were observed and the influence of the living cells on NPs stability and deposition was determined. Using flow cytometry and fluorescence microscopy techniques we studied the kinetics of the cellular uptake of Rubipy-SiO2 NPs by A549 and CaCo-2 cells and we found a correlation between the NPs characteristics in cell media and the amount of cellular uptake. Our results emphasize how relevant and important it is to evaluate and to monitor the size and agglomeration state of nanoparticles in the biological medium, in order to interpret correctly the results of the in vitro toxicological assays.

    Pothwar region of Pakistan is a natural habitat of Olea spp. There is a high demand of certified olive plants to establish olive orchids in the region, because native wild species are non-fruit bearing. Plants of certified fruit bearing olive (Olea europaea L.) cultivars are rarely available. Vegetative propagation of olive is highly responsive to texture of soil based growing media. This study examined the effect of growing media composition (soil texture and nutrients) on vegetative propagation of five cultivars of olive. The experiment was carried out in randomized complete block design (RCBD) with two factors factorial having 25 repeats of each four treatments. Plant growth and survival data were collected and analyzed for the influence of soil attributes. In sandy loam soil, cv. Bari-1 had 82 percent plant survival, highest number of roots per plant (3.5), and longest root length (13.01 cm). Highest number of shoots per plant (4.25) and maximum shoot length (15.64 cm) were also recorded for Bari-1 with sandy loam growing media. Silt loam soil is least suitable growing media for vegetative propagation of olive. In the silt loam soil, plants survival rate was 59 percent for cv. Gemlik, number of roots per plant was 1.5 for cv. Ottobrattica, minimum root length 5.65 cm, minimum number of shoots per plant one, and minimum shoot length 7.42 cm were recorded for cv. Pendolino with silt loam soil. Results suggested that sandy loam growing media is better than the others for vegetative propagation of olive. Cultivar Bari-1 performed better than the others examined in this study by indicating highest (1) survival percentage, (2) root and shoot length, and (3) number of roots and shoots produced within a specific period of time.

    This study compared influences from the mass media (television, music, movies, magazines) on adolescents' sexual intentions and behaviors to other socialization contexts, including family, religion, school, and peers. A sample of 1011 Black and White adolescents from 14 middle schools in the Southeastern United States completed linked mail surveys about their media use and in-home Audio-CASI interviews about their sexual intentions and behaviors. Analysis of the sexual content in 264 media vehicles used by respondents was also conducted. Exposure to sexual content across media, and perceived support from the media for teen sexual behavior, were the main media influence measures. Media explained 13% of the variance in intentions to initiate sexual intercourse in the near future, and 8-10% of the variance in light and heavy sexual behaviors, which was comparable to other contexts. Media influences also demonstrated significant associations with intentions and behaviors after all other factors were considered. All contextual factors, including media, explained 54% of the variance in sexual intentions and 21-33% of the variance in sexual behaviors. Adolescents who are exposed to more sexual content in the media, and who perceive greater support from the media for teen sexual behavior, report greater intentions to engage in sexual intercourse and more sexual activity. Mass media are an important context for adolescents' sexual socialization, and media influences should be considered in research and interventions with early adolescents to reduce sexual activity.

    Full Text Available This study explored the feasibility of using magnetic eggshell-Fe3O4 powder as adsorbent for the removal of Pb(II and Cu(II ions from aqueous solution. The metal ionsadsorption media interaction was characterized using XRD and FTIR. The effects of contact time, initial concentrations, temperature, solution pH and reusability of the adsorption media were investigated. The metal ions adsorption was fast and the amount of metal ions adsorbed increased with an increase in temperature, suggesting an endothermic adsorption. The kinetic data showed that the adsorption process followed the pseudo-second-order kinetic model. The optimal adsorption pH value was around 5.5 at which condition the equilibrium capacity was 263.2 mg/g for Pb(II and 250.0 for Cu(II. The adsorption equilibrium data fitted very well to the Langmuir and Freundlich adsorption isotherm models. The thermodynamics of Pb(II and Cu(II adsorption onto the magnetic eggshell-Fe3O4 powder indicated that the adsorption was spontaneous. The reusability study has proven that magnetic eggshell-Fe3O4 powder can be employed as a low-cost and easy to separate adsorbent.

    Nowadays mass media shape the perception of social values and roles. Thus, aspects of media education that deal with various kinds of inequalities influence general sensitivity to diversity and its consequences. In this respect media and intercultural competences interrelate. Not only minorities’ rights have to be secured, but also majorities rights have to considered if it happens that majorities are discriminated. Widely accepted gender and age inequalities presented on the media in stereot...

    2018-01-01

    Many studies to date have examined how media influence health-related behavior through social norms. However, most studies focused on traditional media. In the era of traditional and social media integration, our study advances health and mass communication scholarship by examining the influence of both traditional and social media mediated through social norms. Also, we examined a boundary condition for the norms-mediated media influence process. Namely, in the context of college binge drinking, we predict that exposure to TV and social media prodrinking messages can influence college students' binge drinking intentions through perceived peer descriptive and injunctive norms. We also predict that group identification will moderate this indirect effect. Our moderated mediation models were tested via structural equation modeling (N = 609). We found that college students' exposure to social media prodrinking messages indirectly influenced their binge drinking intentions via perceived injunctive norms, and students' identification with their peers moderated this indirect effect. However, neither descriptive nor injunctive norms mediated the influence of students' exposure to TV prodrinking messages on their binge drinking intentions. Theoretical and practical implications of the findings are discussed.

    Patients interested in aesthetic plastic surgery procedures increasingly seek advice on social media and rely on easily accessible online information. The investigatory goal was to determine the impact of this phenomenon on the everyday aesthetic plastic surgery practice. Five hundred consecutive patients completed a questionnaire prior to their consultation with a plastic surgeon at our clinic. A questionnaire was also completed by 128 plastic surgeons practising in 19 different countries. A literature review was performed. Almost all patients (95%) used the internet to collect information prior to consultation, for 68% of them it being their first search method. Social media were used by 46% of patients and 40% of these were strongly influenced when choosing a specific doctor. The majority of plastic surgeons (85%) thought the information found on social media could lead to unrealistic expectations. However, 45% of plastic surgeons believed that their consultations became easier after the advent of social media, 29% found them more difficult. A literature review showed a high percentage of poor quality internet websites regarding plastic surgery and an increase in use of social media among plastic surgeons. The internet and social media play an important and growing role in plastic surgery. This results in more informed patients but may create unrealistic expectations. Even if the internet provides ample information, it cannot replace the face-to-face consultation, which always should remain a detailed process, covering both risks and limitations of alternative procedures. Available literature on how social media influences the medical practice is still scarce and further research is needed. This journal requires that authors assign a level of evidence to each article.

  11. Redox-active media for permeable reactive barriers

    In this paper, three classes of redox-active media are described and evaluated in terms of their long-term effectiveness in treating TCE-contaminated groundwater in permeable reactive zones. Zero-valent iron, in the form of recycled cast iron filings, the first class, has received considerable attention as a reactive media and has been used in about a dozen pilot- and full-scale subsurface wall installations. Criteria used in selecting commercial sources of granular iron, will be discussed. Two other classes of redox-active media that have not yet seen wide use in pilot- or full-scale installations will also be described: Fe(II) minerals and bimetallic systems. Fe(II) minerals, including magnetite (Fe 3 O 4 ), and ferrous sulfide (troilite, FeS), are redox-active and afford TCE reduction rates and product distributions that suggest that they react via a reductive mechanism similar to that which operates in the FeO system. Fe(II) species within the passive oxide layer coating the iron metal may act as electron transfer mediators, with FeO serving as the bulk reductant. Bimetallic systems, the third class of redox-active media, are commonly prepared by plating a second metal onto zero-valent iron (e.g., Ni/Fe and Pd/Fe) and have been shown to accelerate solvent degradation rates relative to untreated iron metal. The long-term effectiveness of this approach, however, has not yet been determined in groundwater treatability tests. The results of a Ni-plated iron column study using site groundwater indicate that a change in reduction mechanism (to catalytic dehydrohalogenation/hydrogenation) accounts for the observed rate enhancement. A significant loss in media reactivity was observed over time, attributable to Ni catalyst deactivation or poisoning. Zero-valent iron systems have not shown similar losses in reactivity in long-term laboratory, pilot or field investigations

    Full Text Available Abstract Background Setting priorities for the funding of new anti-cancer agents is becoming increasingly complex. The funding of adjuvant trastuzumab for breast cancer has brought this dilemma to the fore. In this paper we review external factors that may influence decision-making bodies and present a case study of media response in Ontario, Canada to adjuvant trastuzumab for breast cancer. Methods A comprehensive search of the databases of Canadian national and local newspapers and television was performed. Articles pertaining to trastuzumab in adjuvant breast cancer as well as 17 other anti-cancer drugs and indications were retrieved. The search period was from the date when individual trial results were announced to the date funding was made available in Ontario. Results During the 2.6 months between the release of the trastuzumab results to funding approval in Ontario, we identified 51 episodes of media coverage. For the 17 other drugs/indications (7 breast and 10 non-breast, the median time to funding approval was 31 months (range 14–46. Other recent major advances in oncology such as adjuvant vinorelbine/cisplatin for resected NSCLC and docetaxel for advanced prostate cancer received considerably less media attention (17 media reports for each than trastuzumab. The median number of media reports for breast cancer drugs was 4.5 compared to 2.5 for non-breast cancer drugs (p = 0.56. Conclusion Priority-setting for novel anti-cancer agents is a complex process that tries to ensure fair use of constrained resources to fund therapies with the best evidence of clinical benefit. However, this process is subject to external factors including the influence of media, patient advocates, politicians, and industry. The data in this case study serve to illustrate the significant involvement one (or all of these external factors may play in the debate over priority-setting.

    Full Text Available Many studies or facts from the practical experience of many journalist politicians and professors show that the media impact on public opinion is enormous and essential. Many issues of everyday life human crisis or mainstream policies once covered and analyzed from the lenses of the media become the main concerns of the citizens and have a meaningful impact on the attitudes of the public opinion. The migration crisis that is challenging the European countries nowadays is a big concern not only for the host countries citizens but a life challenge for the immigrants themselves. This study will examine of the connection between media reports on immigration and public attitudes and actions and how migration issues presented in the mainstream media impact the public and political discourse on international migration.

  16. SOCIAL MEDIA AND CLASSROOM ENGAGEMENT: STUDENTS’ PERCEPTION

    2016-12-01

    Full Text Available Over the course of the last 15 years or so, social media have shown many facets—from connecting people on a global-scale, to penetrating aspects of lives which otherwise might have remained private or limited to a small audience. In the realm of education, social media have also begun to infiltrate the academic world by influencing and shaping students’ perceptions and influencing learning engagement. With millions of students and teachers simultaneously active on social networks, it is significant to observe how the media could influence student-teacher classroom interactions as well as their online communications. Some studies have documented that teachers who disclosed information about themselves on social media were perceived as more credible by students because they were regarded as more relatable. Moreover, students’ stereotyping beliefs and attitudes towards teachers also come into play when formulating perceptions about teachers on social media. For instance, their communications with teachers are often formal and impersonal on social media, as teachers are viewed as authoritative figures. Consequently, students’ perceptions towards teachers would have a significant repercussion on their interpersonal relationships, which in turn impacts students’ motivation and learning engagement. Thus, this research was conducted to establish preliminary findings whether social media shape students’ perceptions and whether these ramifications would result in positive or negative learning engagement. Consequently, the results indicate that students are more susceptible towards teachers who are active on social media because they are perceived as being more akin to a “real person” who can easily be reached for immediate classroom information and instructions. Such accessibilities via social media enable learning processes to be less contrived by just the physical classroom settings.

Prototype media pembelajaran fisika tentang Hukum II Newton telah dikembangkan dengan mengkombinasikan sensor IR obstacle, NodeMCU, dan sketch program Arduino IDE sebagai counter waktu dan papan track, kubus berlubang, katrol, benang, dan kepingan logam sebagai perangkat pendukung. Hasil eksperimen telah memperlihatkan nilai percepatan benda pada bidang licin lebih besar daripada bidang kasar. Hasil analisis grafik hubungan percepatan vs resultan gaya eksternal menunjukkkan berbanding lurus dan grafik hubungan percepatan vs massa benda menunjukkan berbanding terbalik. Dengan demikian dapat disimpulkan media pembelajaran fisika berbasis NodeMCU mampu memvisualisasikan, menjelaskan dan membuktikan Hukum II Newton. This research is aimed to develop a prototype of physics instructional media based on micro controller. Physics learning media about Newton’s second law prototype has been developed by combining IR sensor obstacle, NodeMCU, and sketch program the Arduino IDE as counter time, and tracking, block, pulley, rope and metal strip as support device. The experimental results show that the value of acceleration of the object on a slippery plane is larger than the rough plane. The results of the analysis of the acceleration and the resultant graph shows that the external force is directly proportional and a graph showing the acceleration vs the object's mass is inversely proportional. Thus we can conclude that Physics learning media based on NodeMCU is valid in explaining and proving Newton's II.

    Media, from television to the "new media" (including cell phones, iPads, and social media), are a dominant force in children's lives. Although television is still the predominant medium for children and adolescents, new technologies are increasingly popular. The American Academy of Pediatrics continues to be concerned by evidence about the potential harmful effects of media messages and images; however, important positive and prosocial effects of media use should also be recognized. Pediatricians are encouraged to take a media history and ask 2 media questions at every well-child visit: How much recreational screen time does your child or teenager consume daily? Is there a television set or Internet-connected device in the child's bedroom? Parents are encouraged to establish a family home use plan for all media. Media influences on children and teenagers should be recognized by schools, policymakers, product advertisers, and entertainment producers. Copyright © 2013 by the American Academy of Pediatrics.

    Sexual content is highly prevalent in traditional media, and portrayals rarely depict the responsibilities and risks (eg, condom use, pregnancy) associated with sexual activity. Exposure to such content is linked with shifts in attitudes about sex and gender, earlier progression to sexual activity, pregnancy, and sexually transmitted infection among adolescents. However, little information is available about moderators and mediators of these effects. We also know little about digital media, their sex-related content, and their potential influence on youth. Data from a few studies of older youth indicate that sexual displays on social media sites are related to problematic beliefs and behaviors among those who post this content and among viewers. Online pornography appears to be more problematic for youth than off-line sources. Given the vast and increasing amount of time youth spend online and their developmental openness to influence, more research attention to digital sexual media is needed. Those who undertake this work should identify potential negative consequences of use and opportunities to improve adolescent sexual health through digital media. Studies of on- and off-line media in which researchers examine younger media audiences, identify processes explaining sexual media effects on behavior, and moderators of effects are needed. Such studies could be used to inform interventions to reduce negative outcomes and increase positive media effects. Policy makers should stimulate the development of such interventions, including tools to help parents identify and manage negative media influences on their children's sexual well-being and development and dissemination of innovative media literacy programs related to sexual health.

    To assess the ability of vaginal lactobacilli to form biofilm under different culture conditions and to determine the relationship between their growth and the capability of biofilm formation by selected strains. Fifteen Lactobacillus strains from human vagina were tested for biofilm formation by crystal violet staining. Only Lactobacillus rhamnosus Centro de Referencia para Lactobacilos Culture Collection (CRL) 1332, Lact. reuteri CRL 1324 and Lact. delbrueckii CRL 1510 were able to grow and form biofilm in culture media without Tween 80. However, Lact. gasseri CRL 1263 (a non-biofilm-forming strain) did not grow in these media. Scanning electron microscopy showed that Lact. rhamnosus CRL 1332 and Lact. reuteri CRL 1324 formed a highly structured biofilm, but only Lact. reuteri CRL 1324 showed a high amount of extracellular material in medium without Tween. Biofilm formation was significantly influenced by the strain, culture medium, inoculum concentration, microbial growth and chemical nature of the support used for the assay. The results allow the selection of biofilm-forming vaginal Lactobacillus strains and the conditions and factors that affect this phenomenon. © 2012 The Society for Applied Microbiology.

    Full Text Available Communication Media has been developed in the form of printed Media and electronic Media.   This development is not only easy to communicate and receive information fast wherever and whenever we go but also cheap. Besides positive impacts, it has negative influence to children and teenagers growth and adults. In other word it brings great influence to people. That is why Media literacy is needed so people will be able to know what Media is. Media presents through a long process. What we see is not 100% true.  There are politics, economics, culture etc in it. People have to know and understand Media. So, media literacy is so important to educate society when they access information in mass media. The program must be doing together, comprehensive from all element in society in structural and cultural way.

    Substantial research has associated exposure to entertainment media with increased levels of interpersonal violence, risky sexual behavior, body image distortion, substance abuse, and obesity. The objective of this study was to determine what pediatric residency programs are teaching trainees about media and the influence of media on the physical and mental health of children and adolescents. Survey of residency curricula, consisting of 17 items about children's exposure to media, including television, movies, popular music, computer/video games and the Internet, the effects of this exposure on specific health risks, and associations between program characteristics and media education in the residency curriculum. Participants. Directors of the 209 accredited pediatric residency programs in the United States. Two hundred four programs (97.6%) responded. Fifty-eight programs (28.4%) offered formal education on 1 or more types of media; 60 programs (29.4%) discussed the influences of media when teaching about specific health conditions. Residents in 96 programs (47.1%) were encouraged to discuss media use with patients and parents; 13 programs (6.4%) taught media literacy as an intervention. Among program characteristics, only media training received by program directors was significantly associated with inclusion of media in residency curricula. Despite increasing awareness of media influence on child health, less than one-third of US pediatric residency programs teach about media exposure. Developing a pediatric media curriculum and training pediatric residency directors or designated faculty may be a resource-effective means of improving health for children growing up in a media-saturated environment.

    In the absence of effective sex education in the United States, the media have arguably become the leading sex educator for children and teenagers. Considerable research now exists that attests to the ability of the media to influence adolescents' attitudes and beliefs about sex and sexuality. In addition, new research has found a significant link between exposure to sexual content in the media and earlier onset of sexual intercourse. Although there is little research on the behavioral effects of "new" media, they are discussed as well. Suggestions for clinicians, parents, the federal government, and the entertainment industry are provided.

    Television consumption influences perceptions of attractive female body size. However, cross-cultural research examining media influence on body ideals is typically confounded by differences in the availability of reliable and diverse foodstuffs. 112 participants were recruited from 3 Nicaraguan villages that differed in television consumption and nutritional status, such that the contribution of both factors could be revealed. Participants completed a female figure preference task, reported their television consumption, and responded to several measures assessing nutritional status. Communities with higher television consumption and/or higher nutritional status preferred thinner female bodies than communities with lower television consumption and/or lower nutritional status. Bayesian mixed models estimated the plausible range of effects for television consumption, nutritional status, and other relevant variables on individual preferences. The model explained all meaningful differences between our low-nutrition villages, and television consumption, after sex, was the most likely of these predictors to contribute to variation in preferences (probability mass >95% when modelling only variables with zero-order associations with preferences, but only 90% when modelling all possible predictors). In contrast, we found no likely link with nutritional status. We thus found evidence that where media access and nutritional status are confounded, media is the more likely predictor of body ideals.

    Interest in adipose-derived stem cells (ASCs) has increased in recent years due to their multi-linage differentiation capabilities. While much work has been done to optimize the differentiation media, few studies have focused on examining the influence of different expansion media on cell behavior. In this study, three basal media (low glucose Dulbecco's modified Eagle's medium (DMEM), high glucose DMEM and DMEM-F12) supplemented with or without fibroblast growth factor 2 (FGF) were examined to assess their suitability for expanding ASCs. Flow cytometry, colony-forming unit assays (CFU-Fs) and differentiation assays were utilized to study cell behavior. High glucose media CFU-Fs produced fewest colonies while the addition of FGF increased colony size. By passage 2, the majority of cells were positive for CD44, 45, 73, 90 and 105 and negative for CD14, 31 and 45, indicating a mesenchymal phenotype. A sub-population of CD34 positive cells was present among passage 2 cells; however, by passage 4 the cells were negative for CD34. FGF has a negative effective on passage 4 ASC adipogenesis and high glucose media plus FGF-enhanced osteogenic capacity of passage 4 ASCs. FGF supplemented basal media were most suitable for chondrogenesis. High glucose media plus FGF appeared to be the most beneficial for priming ASCs to induce a keratocyte phenotype. These findings demonstrate the reciprocal effect FGF and basal media have on ASCs. This research has implications for those interested regenerating bone, cartilage, cornea or adipose tissues.

    Science.gov (United States)

    1994-01-01

    To use the mass media (newspaper, radio, and TV) to reach a large audience with information about AIDS, it is important to choose the media outlets carefully, since they use information that satisfies their audience in content and style. For example, radio, TV, or videos are best to reach illiterate groups. Ways to approach each sector of the written and electronic media include press releases, news conferences, information kits, and personal contacts. Letters to the editor and offers of submitting articles for publication are additional ways to approach newspapers. Audio- or videocassettes with interviews or images conveying HIV/AIDS prevention messages can be submitted to TV and radio stations. It is important to present the information attractively to gain the journalists' attention. News releases should include sources of information and a contact name. It is important to inform the mass media of successes revolving around AIDS prevention, emphasizing local successes. One should identify what media slots have the most influence. For example, a medical officer in Chiang Mai, Thailand, notes that popular disc jockeys have more influence than do government information broadcasts. It is best to promote facts that probably will increase support for AIDS prevention campaigns. If possible, groups should seek free space or air time for AIDS prevention messages. AIDS prevention messages should not use fear because it does not promote safer sexual behavior. Instead, they should link condom use with a sense of independence, responsibility, and being fashionable. Leaflets, posters, videotapes, slides, displays, slogans, audiocassettes, T-shirts, stickers, and other activities or products reinforce the effectiveness of media campaigns. Interviews with or feature articles and programs about people infected or affected by HIV/AIDS chip away at the belief that "AIDS could never happen to me."

    Full Text Available This paper aims to examine how the secular media in Surakarta represent Islam in the case of Charlie Hebdo. Therefore, this study used discourse analysis of Theo van Leeuwen focusing on how the subject or actor of the show in the media. This study concluded that the media represent Islam not only with “Western ideology” through idioms such as radical Islamist militants and terrorists, but also with "Islamic ideology". It is done through the construction of Islam as a religion of moderation and delegitimize Charlie Hebdo as magazine satyr abusing freedom. Various strategies are used ranging from strategy passivation to interdetermination. In this case, there are two poles of attraction in both media, namely the Western and Islamic ideology. If both media are quoting from Western sources, the Western ideology dominates the media narrative. Conversely, when both media used Islamic sources, the influence of Islamic ideology dominates the narrative of both media.

    2018-01-01

    Prior research has examined the influence of media exposure on adolescents' sexualized self-concept, but engagement in sexualizing appearance behaviors remains understudied, especially among a younger age group (i.e., early adolescents). This three-wave panel study among 971 nine- to 14-year-olds (M age  = 12.99, SD = 1.03) showed that discussing media content with friends (i.e., indirect media exposure) was indirectly related to sexualizing appearance behaviors through perceived attainability of the appearance ideal. Direct media exposure was not significantly related to sexualizing appearance behaviors, nor to perceived pressure or perceived attainability. Direct and indirect media exposure influenced boys and girls in similar ways, although the model showed a better fit among the girls. In addition, reward sensitivity did not moderate the examined relations.

The findings show that the influence of “consumer...... socialization of peers” on the social identity of consumers is overestimated. Rather, the main influence comes from peers in the real world. The influence of this real world peer on consumption patterns is much higher than social media peers. Though social media is used for communication of real world peers......This research investigates the effect of social media peers on the social identity of consumers. The critical perspective of this research is based on the consumer socialization theory research framework. This framework consists of three levels - the global, national and local peers...

  1. Agenda-setting, Religion and New Media: The Chabad Case Study

    Directory of Open Access Journals (Sweden)

    Tsuriel Rashi

    2015-12-01

    Full Text Available Theoretically grounded in agenda setting, a theory focused on the transfer of influence from communication media to a public, this paper examines the media activity of Chabad, an Ultra-Orthodox Jewish movement that is committed both to making Judaism generally accessible and to influencing public discourse. Rabbi M. M. Schneerson, the movement’s late wise and charismatic leader, undertook this dual mission in light of his conception of the theological grounds for the exploitation of mass media. Our examination of Chabad’s agenda-setting communication strategy was guided by two research questions: 1. What is the range of communication media used by Chabad in an effort to achieve its goal? 2. What evidence is there regarding the agenda-setting success of these communication efforts? Although it is obviously difficult to judge the precise degree of success, it is clear that Chabad is involved in a wide range of media and public activity and has already influenced public discourse well beyond the range of the movement itself and of the Jewish religion. The answer to the two questions above will help us understand the various movements that try to influence the agenda on religious grounds, so that we can determine the interface between religion and setting the agenda. It may also assist the efforts of other religious groups that want to influence the media and the political agenda.

  4. Dynamics of proteins aggregation. II. Dynamic scaling in confined media

    2018-03-01

    In this paper, the second in a series devoted to molecular modeling of protein aggregation, a mesoscale model of proteins together with extensive discontinuous molecular dynamics simulation is used to study the phenomenon in a confined medium. The medium, as a model of a crowded cellular environment, is represented by a spherical cavity, as well as cylindrical tubes with two aspect ratios. The aggregation process leads to the formation of β sheets and eventually fibrils, whose deposition on biological tissues is believed to be a major factor contributing to many neuro-degenerative diseases, such as Alzheimer's, Parkinson's, and amyotrophic lateral sclerosis diseases. Several important properties of the aggregation process, including dynamic evolution of the total number of the aggregates, the mean aggregate size, and the number of peptides that contribute to the formation of the β sheets, have been computed. We show, similar to the unconfined media studied in Paper I [S. Zheng et al., J. Chem. Phys. 145, 134306 (2016)], that the computed properties follow dynamic scaling, characterized by power laws. The existence of such dynamic scaling in unconfined media was recently confirmed by experiments. The exponents that characterize the power-law dependence on time of the properties of the aggregation process in spherical cavities are shown to agree with those in unbounded fluids at the same protein density, while the exponents for aggregation in the cylindrical tubes exhibit sensitivity to the geometry of the system. The effects of the number of amino acids in the protein, as well as the size of the confined media, have also been studied. Similarities and differences between aggregation in confined and unconfined media are described, including the possibility of no fibril formation, if confinement is severe.

    Nelson, Kimberly M; Pantalone, David W; Gamarel, Kristi E; Simoni, Jane M

    2016-01-01

    Men who have sex with men (MSM) frequently consume sexually explicit online media (SEOM), yet little is known about its influence on their sexual behaviors. We describe a sequence of four studies to develop and psychometrically validate a measure of the perceived influence of sexually explicit online media (PI-SEOM) on the sexual behaviors of MSM. Study 1 involved qualitative interviews (N = 28) and a quantitative survey (N = 100) to develop a preliminary measure. Using an Internet sample of MSM (N = 1,170), we assessed its factor structure and reliability in Studies 2 and 3 as well as convergent validity and associations with HIV-related sexual risk in Study 4. Based on findings the measure was divided into two subscales: influences on (1) self and (2) other MSM. Factor analyses confirmed a two-factor model for each subscale, measuring perceived influences on (a) general sexual scripts and (b) condomless sex scripts. Survey results indicated that the more men perceived SEOM influencing their own condomless sex scripts, the more likely they were to report engaging in sexual risk behaviors. The developed measure holds promise for assessing the influence of SEOM on the sexual behaviors of MSM and may prove useful for HIV-prevention research.

  8. Social media, help or hindrance: what role does social media play in young people's mental health?

    Science.gov (United States)

    Lloyd, Alfie

    2014-11-01

    Social media is a huge force in the lives of young people with wide ranging effects on their development; given the importance of adolescence in the genesis of mental illness, social media is a factor in the mental health of young people. Despite the role that social media obviously plays in the development of mental illness, little research has been done into the impact that social media has on in the mental illness of young people. In general, what research there is points towards social media having a large impact on young people in both positive and negative ways. In particular, certain studies show a greater incidence and severity of bullying online compared to offline which may contribute to the development of depression. This contrasts with the positive impact that social media seems to have for young people in minority groups (ethnic minorities and those with chronic disease or disability) by allowing them to connect with others who live similar lives despite geographical separation. This acts as a positive influence in these people's lives though a direct link to mental illness was not shown. Overall, several important issues are raised: firstly, the lack of research that has been conducted in the area; secondly, the gulf that exists between the generation of younger, 'digital native' generations and the older generations who are not as engaged with social media; and finally, the huge potential that exists for the use of social media as a protective influence for adolescents. With proper engagement, policy makers and health professionals could use social media to connect with young people on issues like mental health.

    Fear of infectious disease often motivates people to protect themselves. But, it can also produce negative bio-social-psychological effects whose severity is on par with those of the disease. The WHO declaration of Zika as a world health crisis presented an opportunity to study factors that bring about fear. Beginning nine days after the WHO announcement, data were gathered from women aged 18-35 living in the southern United States (N = 719). Respondents reported experiencing fear of Zika at levels akin to those reported following other significant crises/disasters (e.g., the terrorist attacks of 9/11). Fear increased as a function of (1) personal, but not other-relevance, (2) frequency of media exposure, but not media content, and (3) frequency of interpersonal exposure and interpersonal content. It is argued that media and interpersonal message sources may be innately predisposed to amplify, rather than attenuate, risk. © 2018 Society for Risk Analysis.

    The main purpose of this study is to investigate the prevalence of medical disputes among plastic surgeons in Taiwan and to elucidate their perspectives regarding the influence of medical litigation media coverage on the physician-patient relationship. A self-administered questionnaire was distributed among plastic surgeons attending a series of continuing education training lectures organized by the Taiwan Society of Plastic Surgery in 2015. Of the 109 respondents, over a third (36.4%) had previously experienced a medical dispute. The vast majority of both physicians who had medical disputes (77.1%) and those who did not (72.1%) felt that the media tends to be supportive of patients in their reporting, and 37.1% of all plastic surgeons felt that the media always portrays the patient as a victim. Respondents who experienced medical disputes in this study felt that the top five leading causes of the high incidence of medical disputes were patient disappointment with procedure results (81.1%), insufficient patient psychological preparation or emotional instability (61.7%), inadequate risk communication on the part of the physician (64.9%), patient uneasiness with the procedure or perception of carelessness (60.6%), and insufficient physician training or incorrect medical evaluation (57.4%). Over a third of the respondents had previously experienced a medical dispute. This study highlights the perception among plastic surgeons that the media reporting of medical disputes and medical litigation is biased in favor of the patients, with 37.1% of the plastic surgeons surveyed opining that patients are always cast as victims.

    The authors examined the influence of social media involvement on health issues in sexual and gender minorities (SGMs). Demographic and technological characteristics of social media users and nonusers were identified, and the influence of social media involvement on these factors was assessed for its potential to influence health information needs and preferences. A survey of 2,274 SGM individuals revealed that age, sexual orientation, number of Internet access points, and use of smartphones predicted levels of social media involvement. Results suggest that a broader range of traditional and nontraditional communication channels is needed to meet a diversity of health information needs in SGMs.

  15. Surface-wave solitons between linear media and nonlocal nonlinear media

    2011-01-01

    We address surface solitons at the interface between linear media and nonlocal nonlinear media in the presence of a discontinuity in refractive index at the surface of these two materials. We investigated the influence of the degree of nonlocality on the stability, energy flow, and full width at half-maximum of the surface wave solitons. It is shown that surface solitons will be stable only if the degree of nonlocality exceeds a critical value. We find that the refractive index difference can affect the power distribution of the surface solitons in the two media. Also, different boundary values at the interface can lead to different relative peak positions of the surface solitons. However, neither the refractive index nor the boundary conditions can affect the stability of the solitons, for a given degree of nonlocality.

    Worries about health threatening effects of potential health hazards of modern life (e.g. electric devices and pollution) represent a growing phenomenon in Western countries. Yet, little is known about the causes of this growing special case of affective risk perceptions termed Modern Health Worries (MHW). The purpose of this study is to examine a possible role of biased media reports in the formation of MHW. In two experiments, we investigated whether typical television reports affect MHW. In Study 1, 130 participants were randomly assigned to a film on idiopathic environmental intolerance (IEI) or a control film about cystic fibrosis. In Study 2, 82 participants were randomly assigned to either a film on the dangers of electromagnetic fields or a control condition. Increases in MHW after sensational media reports. In Study 1, only participants high on the personality trait of absorption revealed increased MHW after watching the IEI film. In Study 2, specifically worries about radiation were found to be elevated after watching the film on the dangers of electromagnetic fields compared to the control film. The results of both studies reveal a significant and specific influence of sensational short mass media reports on MHW. The influence of potential moderators such as absorption remains to be clarified.

    2012-01-01

    Starch, a homopolysaccharide is an important and an abundant food reserve and energy source. Starches are processed to yield different products which find many industrial applications. Alpha-amylases hydrolyze starch by cleaving α-1,4-glucosidic bonds and have been used in food, textile and pharmaceutical industries [Sun et al. 2010]. Enzymatic conversion of starch with amylase presents an economically superior alternative to the conventional method of starch gelatinization. Alkaline α-amylase has an important position in the global enzyme market as a constituent of detergent. In this paper, we screened soil bacteria and an isolate, alkalophilic Bacillus subtilis CB-18 was found to produce an alkaline α-amylase in different media. MATERIAL AND METHODS. Screening of the isolates for amylolytic activity was carried out by growing bacteria isolated from the soil in starch agar plates and subsequently staining the plates with iodine solution to reveal zones of hydrolysis of starch. The selected isolate, Bacillus subtlis CB-18 was grown in different media at alkaline pH to evaluate the influence of media composition on alkaline α-amylase production. Enzyme assay was carried out by growing the culture in a broth medium and obtaining cell - free culture supernatant after centrifugation at 2515 × g for 15 minutes Amylase activity was determined by incubating 0.5 ml of crude enzyme solution in 0.1M Tris/HCl buffer (pH 8.5) with 0.5 ml of 1% soluble starch solution. The reaction was terminated by the addition of DNS reagent and reducing sugar produced from the amylolytic reaction was determined. Bacillus subtilis CB-18 used for this work was selected because it produced 7 mm zone diameter on starch agar plate. This organism was cultured in different alkaline broth media containing 2% soluble starch as inducer carbohydrate for α-amylase production. Among the carbon sources used for enzyme production, sorbitol was the best to stimulate enzyme production with

    Harmful use of alcohol-the prime gateway drug to other addictions-is also a problem in Cuba, even though the National Program for Prevention of Harmful Use of Alcohol includes the most effective measures used in analogous programs around the world. As a participant in the program's committee and empirical observer of its accomplishments and unaccomplished goals, I draw attention to the community's attitude of tolerance toward intoxication manifested by the lack of proportional consequences, and I insist on the need to broaden the community's understanding of the risks of non-social drinking, which in Latin America is practically limited to alcoholism and its complications. This undervalues the damage wreaked by unpredictable and dangerous behavior under the influence, as well as the suffering of codependents and other "passive drinkers," and the adverse effects of even social drinking.

    2018-04-01

    Family dynamics are increasingly being influenced by digital media. Three frameworks are described to help clinicians to understand and respond to this influence. First, a social-ecological framework shows how media has both a direct and indirect impact on individuals, relationships, communities, and society. Next, family systems theory is introduced to demonstrate digital media-related interactions within families. Finally, a developmental framework explores the role of digital media in shaping parenting. These theories are then integrated into practical strategies that clinicians can use, including recommendations and resources from the American Academy of Pediatrics. Copyright © 2017 Elsevier Inc.

    Mass media are increasingly used to deliver health messages to promote social and behaviour change, but there has been little evidence of mass media use for improving a set of child feeding practices, other than campaigns to promote breastfeeding. This study aimed to examine the factors influencing the uptake of infant and young child feeding messages promoted in TV spots that were launched and aired nationwide in Bangladesh. We conducted a mixed-methods study, using household surveys (n = 2,000) and semistructured interviews (n = 251) with mothers of children 0-23.9 months and other household members. Factors associated with TV spot viewing and comprehension were analysed using multivariable logistic regression models, and interview transcripts were analysed by systematic coding and iterative summaries. Exposure ranged from 36% to 62% across 6 TV spots, with comprehension ranging from 33% to 96% among those who viewed the spots. Factors associated with comprehension of TV spot messages included younger maternal age and receipt of home visits by frontline health workers. Three direct narrative spots showed correct message recall and strong believability, identification, and feasibility of practicing the recommended behaviours. Two spots that used a metaphorical and indirect narrative style were not well understood by respondents. Understanding the differences in the uptake factors may help to explain variability of impacts and ways to improve the design and implementation of mass media strategies. © 2018 The Authors.

    2017-07-01

    Popular media influences ideas about science constructed by the public. To sway media productions, public policy organizations have increasingly promoted use of science consultants. This study contributes to understanding the connection from science consultants to popular media to public outcomes. A science-based television series was examined for intended messages of the creator and consulting scientist, and received messages among middle school and non-science university students. The results suggest the consulting scientist missed an opportunity to influence the portrayal of the cultural contexts of science and that middle school students may be reading these aspects uncritically-a deficiency educators could potentially address. In contrast, all groups discussed the science content and practices of the show, indicating that scientific facts were salient to both media makers and audiences. This suggests popular media may influence the public knowledge of science, supporting concerns of scientists about the accuracy of fictional television and film.

    Full Text Available Medical societies, faculty, and trainees use Twitter to learn from and educate other social media users. These social media communities bring together individuals with various levels of experience. It is not known if experienced individuals are also the most influential members. We hypothesize that participants with the greatest experience would be the most influential members of a Twitter community. We analyzed the 2013 Association of Program Directors in Internal Medicine Twitter community. We measured the number of tweets authored by each participant and the number of amplified tweets (re-tweets. We developed a multivariate linear regression model to identify any relationship to social media influence, measured by the PageRank. Faculty (from academic institutions comprised 19% of the 132 participants in the learning community (p < 0.0001. Faculty authored 49% of all 867 tweets (p < 0.0001. Their tweets were the most likely to be amplified (52%, p < 0.01. Faculty had the greatest influence amongst all participants (mean 1.99, p < 0.0001. Being a faculty member had no predictive effect on influence (β = 0.068, p = 0.6. The only factors that predicted influence (higher PageRank were the number of tweets authored (p < 0.0001 and number of tweets amplified (p < 0.0001 The status of “faculty member” did not confer a greater influence. Any participant who was able to author the greatest number of tweets or have more of his/her tweets amplified could wield a greater influence on the participants, regardless of his/her authority.

    2011-11-01

    Research suggests that the representation of scientific and medical issues in the traditional media such as newspapers, TV and radio is an important determinant of public opinion and related public policy outcomes, particularly with regard to attitudes toward stem cell research. With the emergence of social media, the discursive space around public policy issues has expanded to include a new demographic of media consumer who is directly involved in political action. However, little is known about the influence of social media on scientific public policy conversations. We analyzed Twitter posts on two topics relating to stem cell science and policy according to the originator and tone of the tweet, and whether the tweet was intended to be neutral or to further a stated policy position. This analysis provides a means for clarifying the role of social media in influencing public opinion of policy issues such as stem cell research and offers organizations a better understanding of how to more effectively apply social media to advancing their stem cell policy positions.

    This study examined the relationships across social media use, social support, depression, and general psychological disposition among people with movement or mobility disabilities in Korea. First, with survey data (n = 91) collected from users of social network sites (SNSs) and online communities, hypotheses regarding positive associations between intensity of an individual's engagement in social media and four different types of social support-emotional, instrumental, informational, and appraisal support-were tested as well as hypotheses regarding mediation effects of the social support variables in the association between social media use and depression. Second, through focus group interviews (n = 15), influences of social media use on social support were more thoroughly explored as well as their influences on general psychological disposition. Results from hierarchical regression analyses confirmed that both intensity of SNS use and online community use significantly predicted instrumental, informational, and appraisal support, while they did not predict emotional support. Further regression and Sobel tests showed that higher levels of intensity of SNS use and of online community use both led to lower levels of depression through the mediation of instrumental and informational support. Analysis of the interviews further revealed the positive roles of social media use in building social support and healthy psychological dispositions. However, analysis also revealed some negative consequences of and limitations to social media use for those with physical disabilities. These findings expand our knowledge of the context and implications of engaging in online social activities for people with physical disabilities.

  16. Media and children's aggression, fear, and altruism.

    Science.gov (United States)

    Wilson, Barbara J

    2008-01-01

    Noting that the social and emotional experiences of American children today often heavily involve electronic media, Barbara Wilson takes a close look at how exposure to screen media affects children's well-being and development. She concludes that media influence on children depends more on the type of content that children find attractive than on the sheer amount of time they spend in front of the screen. Wilson begins by reviewing evidence on the link between media and children's emotions. She points out that children can learn about the nature and causes of different emotions from watching the emotional experiences of media characters and that they often experience empathy with those characters. Although research on the long-term effects of media exposure on children's emotional skill development is limited, a good deal of evidence shows that media exposure can contribute to children's fears and anxieties. Both fictional and news programming can cause lasting emotional upset, though the themes that upset children differ according to a child's age. Wilson also explores how media exposure affects children's social development. Strong evidence shows that violent television programming contributes to children's aggressive behavior. And a growing body of work indicates that playing violent video games can have the same harmful effect. Yet if children spend time with educational programs and situation comedies targeted to youth, media exposure can have more prosocial effects by increasing children's altruism, cooperation, and even tolerance for others. Wilson also shows that children's susceptibility to media influence can vary according to their gender, their age, how realistic they perceive the media to be, and how much they identify with characters and people on the screen. She concludes with guidelines to help parents enhance the positive effects of the media while minimizing the risks associated with certain types of content.

    Full Text Available The paper aims at discussing the challenges and opportunities of laboratory experiments for communicationstudies. An experimental approach to research on TV news effects is presented. It focuses on interpersonal communication about a newscast and simulates the social context of media use and media effects. Based upon two research domains, (1 The role of interpersonal communication in media effects and (2 TV news reception, five hypotheses are derived which are tested in an innovative experimental design integrating survey and observation methods in a combination of media effects study and small group experiment. The influence of conversations on news memory and evaluation is assessed by treating conversations as independent variable in the experiment. In a video observation, the mechanisms of interpersonal communication about the media are identified. A moderating influence of conversations, specifically an enhanced news recall, is revealed. Additionally, the characteristics of the social processing of the media content can be described and applied as possible explanations for the effects of the experimental treatment. Consequently, the advantages of integrative research designs are explicated.

    Time spent on social media and making online comparisons with others may influence users' mental health. This study examined links between parental control over the time their child spends on social media, preadolescents' time spent browsing social media, preadolescents' appearance comparisons on social media, and preadolescents' appearance satisfaction, depressive symptoms, and life satisfaction. Preadolescent social media users (N = 284, 49.1% female; aged 10-12) and one of their parents completed online surveys. Preadolescents, whose parents reported greater control over their child's time on social media, reported better mental health. This relationship was mediated by preadolescents spending less time browsing and making fewer appearance comparisons on social media. Parental control over time spent on social media may be associated with benefits for mental health among preadolescents.

    A comparative evaluation was done to test the accuracy of the Cathra Repliscan II agar dilution system (Diagnostic Equipment, Inc., St. Paul, Minn.), the AutoMicrobic system with Gram-Negative General Susceptibility-Plus Card (Vitek Systems, Inc., Hazelwood, Mo.), and the Micro-Media Fox Panel micro broth dilution system (Micro-Media Systems, Inc., San Jose, Calif.) in determining MICs of 12 antibiotics for 200 gram-negative bacilli. Of the 200 strains tested, 12 isolates did not grow in one of the three systems. The 188 remaining organisms included 158 members of the family Enterobacteriaceae, 20 Pseudomonas spp., 5 Acinetobacter sp., 3 Aeromonas spp., and 2 Vibrio spp. A total of 2,256 organism-antibiotic combinations were analyzed for each system. An MIC was considered correct if two of the three systems were in agreement. When disagreements occurred, correct MICs were determined by the standard agar dilution method. With this criterion, overall agreements of the Cathra Repliscan II system, AutoMicrobic system, and Micro-Media Fox Panel system were 94.7, 94.9, and 95.5%, respectively. Tetracycline (20%), nitrofurantoin (20%), and ampicillin (16%) accounted for 56% of the discrepancies observed. These results indicate that all three systems perform with a high degree of accuracy for susceptibility testing of gram-negative bacilli.

    2010-07-01

    Radio, television (TV), movies, video games, cell phones, and computer networks have assumed central roles in our children's daily lives. The media has demonstrated potentially profound effects, both positive and negative, on children's cognitive, social, and behavioral development. Considering the increasing exposure of children to newer forms of media, we decided to review the current literature on the effects of media on child health both in the Western countries and India. It is widely accepted that media has profound influence on child health, including violence, obesity, tobacco and alcohol use, and risky sexual behaviors. Simultaneously, media may have some positive effects on child health. We need to find ways to optimize the role of media in our society, taking advantage of their positive attributes and minimizing their negative ones. We need to understand better how to reverse the negative impact of media and make it more positive.

    2016-03-07

    The formation of a gel coat around xanthan (Xan) tablets, empty or loaded with pentoxifylline (PF), and its release in media differing in pH and ionic strength by NMR, MR imaging, and two release methods were studied. The T1 and T2 NMR relaxation times in gels depend predominantly on Xan concentration; the presence of PF has negligible influence on them. It is interesting that the matrix swelling is primarily regulated by Xan despite high drug loading (25%, 50%). The gastric pH and high ionic strength of the media do not influence the position of the penetration and swelling fronts but do affect the erosion front and gel thickness. The different release profiles obtained in mixing and nonmixing in vitro methods are the consequence of matrix hydration level and erosion at the surface. In water and in diluted acid medium with low ionic strength, the main release mechanism is erosion, whereas in other media (pH 1.2, μ ≥ 0.20 M), anomalous transport dominates as was found out by fitting of measured data with theoretical model. Besides the in vitro investigation that mimics gastric conditions, mathematical modeling makes the product development more successful.

  9. THE INFLUENCE OF MEDIA EXPOSURE, SAFETY AND HEALTH CONCERNS, AND SELF-EFFICACY ON ENVIRONMENTAL ATTITUDES TOWARDS ELECTRONIC GREEN PRODUCTS

    Directory of Open Access Journals (Sweden)

    Iman Khalid A. Qader

    2011-07-01

    Full Text Available As the high-tech industry evolves at a rapid pace, vast amounts of hazardous materials are used in fuelling its global expansion. These rapid changes in production processes are significantly depleting natural resources. With the surge of popular interest and awareness pertaining to environmental issues, organisations may be in peril if consumers' attitudes towards their products are ignored. This study intends to understand consumers' environmental attitudes towards electronic green products and to identify the effect of three factors, namely, media exposure, safety and health concerns, and self- efficacy, on this attitude. Data were collected via a self-administered questionnaire among 170 respondents in a public university. The results of the study indicated that safety and health concerns as well as self-efficacy had significant positive impacts on consumers' environmental attitudes. Surprisingly, however, media exposure did not exhibit any significant influence on consumers' environmental attitude. It is recommended that campaign and awareness projects focus on safety and health issues. Additionally, media should play a more active role in increasing environmental awareness among consumers.

    Social media has been cited as a methodology for reducing the knowledge translation gap, creating communities of practice, and reducing traditional hierarchical divisions. Social movements have also embraced social media as a means of spreading their aims and reaching wide audiences. However, its impact on health policy is seldom considered. The author examines the complexity of clinicians' use of social media to influence policy and how policy and government groups may use social media to help their own objectives.

    Hormone contamination of aquatic systems has been shown to have deleterious effects on aquatic biota. However, the assessment of hormone contamination of aquatic environments requires a quantitative evaluation of the potential effects of sample preservation on hormone concentrations. This study investigated the influence of acidification (pH 2) of surface water samples on the partitioning of hormones among filtrate, filter media, and filter-retained particulate matter. Hormones were spiked into unpreserved and sulfuric acid-preserved ultrapure water and surface water runoff samples. The samples were filtered, and hormones were extracted from the filter and filtrate and analyzed by high-performance liquid chromatography. Acidification did not influence the partitioning of hormones onto the filter media. For the majority of the hormones investigated in this study, the partitioning of hormones to the filter-retained particulate matter was not influenced by acidification. Acidification increased the partitioning of progesterone and melengestrol acetate onto the retained particulate matter (about 25% for both analytes). Incorporation of an isotopically labeled internal standard (ISTD) for progesterone accounted for the loss of progesterone to the filter-retained particulates and resulted in accurate concentrations of progesterone in the filtrate. The incorporation of an ISTD for melengestrol acetate, however, was unable to account for the loss of melengestrol acetate to the retained particulates and resulted in underestimations of melengestrol acetate in the filtrate. Our results indicate that the analysis of melengestrol acetate in acid preserved surface runoff samples should be conducted on the filter-retained particulates as well as the filtrate.

    Ma, Mingju; Liu, Sanyang; Li, Jun

    2017-09-01

    In this paper, a three dimensional drug model is constructed to investigate the impact of media coverage on the spread and control of drug addiction. The dynamical behavior of the model is studied by using the basic reproduction number R0. The drug-free equilibrium is globally asymptotically stable if R0 drug addiction equilibrium is locally stable if R0 > 1. The results demonstrate that the media effect in human population cannot change the stabilities of equilibria but can affect the number of drug addicts. Sensitivity analyses are performed to seek for effective control measures for drug treatment. Numerical simulations are given to support the theoretical results.

  16. Glutathione synthesis and homeostasis in isolated type II alveolar cells

    1986-01-01

    After isolation of Type II cells from neonatal rat lung, the glutathione (GSH) levels in these cells were greatly depressed. The total glutathione content could be increased 5-fold within 12-24 h by incubating the cells in media containing sulfur amino acids. Similarly, the activity of γ-glutamyltranspeptidase was low immediately after isolation, but was increased 2-fold during the first 24 h culture. Addition of either GSH or GSSG to the culture media increased the GSH content of Type II cells 2-2.5-fold. Buthionine sulfoximine and NaF prevented this replenishment of GSH during 24 h culture. When the rates of de novo synthesis of GSH and GSSG from 35 S-cysteine were measured, the amounts of newly formed GSH decreased to 80% in the presence of GSH or GSSG. This suggests that exogenous GSH/GSSG can be taken up by the Type II cells to replenish the intracellular pool of GSH. Methionine was not as effective as cysteine in the synthesis of GSH. These results suggest that GSH levels in the isolated Type II cell can be maintained by de novo synthesis or uptake of exogenous GSH. Most of the GSH synthesized from cysteine, however, was excreted into the media of the cultured cells indicative of a potential role for the type II cell in export of the non-protein thiol

    To evaluate the histopathologic changes of dark, transitional, and hair cells of the vestibular system in human temporal bones from patients with chronic otitis media. Comparative human temporal bone study. Otopathology laboratory. To compare the density of vestibular dark, transitional, and hair cells in temporal bones with and without chronic otitis media, we used differential interference contrast microscopy. In the chronic otitis media group (as compared with the age-matched control group), the density of type I and type II hair cells was significantly decreased in the lateral semicircular canal, saccule, and utricle (P otitis media group in the posterior semicircular canal (P = .005), but that of type II cells was not (P = .168). The mean number of dark cells was significantly decreased in the chronic otitis media group in the lateral semicircular canal (P = .014) and in the posterior semicircular canal (P = .002). We observed no statistically significant difference in the density of transitional cells between the 2 groups (P > .1). The findings of our study suggest that the decrease in the number of vestibular sensory cells and dark cells could be the cause of the clinical symptoms of imbalance of some patients with chronic otitis media. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

It is to be explored how these medical soap operas, medical dramas, medical thrillers or crime stories do exert influence on medical identity and role expectations. Do medical students and their relatives (withmedical expertise frequently identify themselves with these roles? Is their way of reception critical or naïve? How media rituals are organizing, modulating the students’ medical perception and expectations. Is there a mediated “shadow initiation” via media or it is excluded and denied? Does it perfuse the common social experience of becoming a doctor via peer communication and peer shapingof model behavior? We search the answers in the context of a theory of media rituals.

    2014-01-01

    Fashions and fads are important phenomena that influence many individual choices. They are ubiquitous in human societies, and have recently been used as a source of data to test models of cultural dynamics. Although a few statistical regularities have been observed in fashion cycles, their empirical characterization is still incomplete. Here we consider the impact of mass media on popular culture, showing that the release of movies featuring dogs is often associated with an increase in the popularity of featured breeds, for up to 10 years after movie release. We also find that a movie's impact on breed popularity correlates with the estimated number of viewers during the movie's opening weekend--a proxy of the movie's reach among the general public. Movies' influence on breed popularity was strongest in the early 20th century, and has declined since. We reach these conclusions through a new, widely applicable method to measure the cultural impact of events, capable of disentangling the event's effect from ongoing cultural trends.

    Non-self-consistent and self-consistent methods of estimating velocity and attenuation of P waves and S waves at all frequencies for heterogeneous media with three-dimensional inclusions are formulated using the scattering functions of the individual inclusions. The methods are the generalization of methods for one-dimensional media presented in the first paper of this series. The specific case of spherical inclusions is calculated with the exact scattering function and compared with several low frequency approximations. The self-consistent estimates are consistent with Berryman close-quote s low frequency approximation. We present spectra and wave forms of materials with solid and liquid inclusions in a solid matrix. The results show that the exact scattering functions are required to adequately describe wave propagation at all frequencies. The analysis of liquid inclusions demonstrates that viscous damping may become important only if scattering attenuation due to spherical pores is small

    Illicit drugs are never far from the media gaze and although identified almost a decade ago as 'a new battleground' for the alcohol and other drug (AOD) field there has been limited research examining the role of the news media and its effects on audiences and policy. This paper draws together media theories from communication literature to examine media functions. We illustrate how each function is relevant for media and drugs research by drawing upon the existing literature examining Australian media coverage during the late 1990s of escalating heroin-related problems and proposed solutions. Media can influence audiences in four key ways: by setting the agenda and defining public interest; framing issues through selection and salience; indirectly shaping individual and community attitudes towards risk; and feeding into political debate and decision making. Each has relevance for the AOD field. For example, media coverage of the escalating heroin-related problems in Australia played a strong role in generating interest in heroin overdoses, framing public discourse in terms of a health and/or criminal issue and affecting political decisions. Implications AND CONCLUSION: Media coverage in relation to illicit drugs can have multifarious effects. Incorporating media communication theories into future research and actions is critical to facilitate understanding of the short- and long-term impacts of media coverage on illicit drugs and the avenues by which the AOD field can mitigate or inform future media debates on illicit drugs. © 2010 Australasian Professional Society on Alcohol and other Drugs.

  3. Sub-Saharan Africa's media and neocolonialism.

    Given the heavy Western metropolitan bias of the media in sub-Saharan Africa, the ideology of neocolonialism continues to exert a dominant influence on economic, social, political, and cultural life. This neocolonial influence is further reinforced by advertising that champions a consumerist culture centered around Western goods. The capital of multinational firms plays a crucial role in the strategy of media imperialism. The dramatic growth of monopolies and the creation of military-industrial-information conglomerates in the 1970s and 1980s have been reflected in the international exchange of information and the interlinkage of mass communication systems in sub-Saharan Africa. Another media strategy that reinforces neocolonialism is the use of satellite communication. If cultural autonomy is defined as sub-Saharan Africa's capacity to decide on the allocation of its environmental resources, then cultural synchronization is a massive threat to that autonomy. Few African nations have the resources or expertise necessary to design, establish, or maintain communication systems that could accurately reflect their own culture. Nonetheless, there are some policy options. Personnel can be trained to respect African values and to recognize the dangers of neocolonial domination. The production of indigenous programs could reduce the media's foreign content. The incorporation of traditional drama and dance in the media could enhance this process. Above all, a high degree of planning is necessary if sub-Saharan African states intend to tackle the media and its domination by neocolonialist ideology.

    Full Text Available Nowadays mass media shape the perception of social values and roles. Thus, aspects of media education that deal with various kinds of inequalities influence general sensitivity to diversity and its consequences. In this respect media and intercultural competences interrelate. Not only minorities’ rights have to be secured, but also majorities rights have to considered if it happens that majorities are discriminated. Widely accepted gender and age inequalities presented on the media in stereotypes and safely-looking conservatist behaviours may lead to harassment and even violence. That is why understanding media messages and identifying overt and covert forms of discrimination are of special interest of educators. In this article several activities for class teachers are presented to encourage them to introduce the touchy topic of gender and age inequalities into their school practice.

    Full Text Available Setelah serangan 11 September 2001 atas gedung World Trade Center, AS, kata Islam mejadi topik aktual dalam berbagai media barat, yang disandingkan dengan istilah-istilah terorisme, fundamentalisme, vadalisme, dan kata-kata berkonotasi buruk lainnya. Media barat, bahkan telah mengonstruksi persepsi tentang pertentangan Islam dan Barat dengan Amerika sebagai pemimpinnya. Sejak itu, secara perlahan tapi pasti, media barat memberitakan dunia Islam dalam gambaran begitu buruk: gambar-gambar para demonstran Pakistan, wanita yang ditangannya Quran dan pedang, film-film yang bertendensi anti-Islam. Ditayangkan berulangulang, terus-menerus, tiap hari. Upaya merendahkan Islam, bukan sekadar dalam ungkapan implisit, atau lewat gambar-gambar buruk, tapijuga sudah pada tingkat terang-terangan yang begitu eksplisit, seperti ungkapan: peradaban Islam lebih rendah daripada Kristen, orang Islam tidak beradab atau barbar, mengatasi terorisme Islam harus melalui pembaratan. Media barat menjadi kehilangan objektiviitas. Liputan tentang Islam, sebagian besar sekadar berita atau opini negatif; terjadi distorsi begitujauh. Media mengingkari kenyataan bahwa sesungguhnya Islam bukan hanya di anut oleh bangsa Timur Tengah, tapi juga oleh banyak ras dan bangsa lain, termasuk sebagian masyarakat barat. Pada kehdiuan sosial, akibatnya, para muslim minoritas di barat, sering diperlakukan tidak adil. Terdapat diskriminasi untuk nonEropa dan non-Kristen, khususnya Islam. Citra buruk tentang Islam di media barat. memang berlangsung jauh sebelum peristiwa II September. Ketika Uni Soviet bubar, Amerika dan sekutunya kehilangan musuh nomor satu; permusuhan itu kemudian diarahkan kepada Islam, yang dipandang sebagai ancaman. Untuk membangunjurnalisme barat yang objektif" maka media barat perllu membangun sikap terbuka dan mengakui kenyataan bahwa masyarakat itu, bahkan di negaranya sendiri, plural.

    2006-09-01

    This study aimed to prospectively examine the role of peer and media influences in the development of body satisfaction (incorporating the desire for thinness and satisfaction with appearance) in young girls, as well as the relationship between body satisfaction and self-esteem. A sample of 97 girls 5-8 years of age completed individual interviews at Time 1 and 1 year later at Time 2. Linear panel analyses found that Time 1 perception of peers' desire for thinness was temporally antecedent to girls' desire for thinness, appearance satisfaction, and self-esteem 1 year later. In addition, the watching of appearance-focused television programs was temporally antecedent to appearance satisfaction. Finally, girls' desire for thinness was found to temporally precede low self-esteem. Thus, as early as school entry, girls appear to already live in a culture in which peers and the media transmit the thin ideal in a way that negatively influences the development of body image and self-esteem.

    Plant growth regulators, such as hormones and their respective biosynthesis inhibitors, are effective tools to elucidate the physiological function of phytohormones in plants. A problem of chemical treatments, however, is the potential for interaction of the active compound with the growth media substrate. We studied the interaction and efficacy of propiconazole, a potent and specific inhibitor of brassinosteroid biosynthesis, with common soilless greenhouse growth media for rice, sorghum, and maize. Many of the tested growth media interacted with propiconazole reducing its efficacy up to a hundred fold. To determine the molecular interaction of inhibitors with media substrates, Fourier Transform Infrared Spectroscopy and sorption isotherm analysis was applied. While mica clay substrates absorbed up to 1.3 mg of propiconazole per g substrate, calcined clays bound up to 12 mg of propiconazole per g substrate. The efficacy of the gibberellic acid biosynthesis inhibitor, uniconazole, and the most active brassinosteroid, brassinolide, was impacted similarly by the respective substrates. Conversely, gibberellic acid showed no distinct growth response in different media. Our results suggest that the reduction in efficacy of propiconazole, uniconazole, and brassinolide in bioassays when grown in calcined clay is caused by hydrophobic interactions between the plant growth regulators and the growth media. This was further confirmed by experiments using methanol-water solvent mixes with higher hydrophobicity values, which reduce the interaction of propiconazole and calcined clay.

  17. On the influence of T-Stress on photoelastic analysis under pure mode II loading

    Directory of Open Access Journals (Sweden)

    Chiara Colombo

    2008-01-01

    Full Text Available According to the classical definition for in-plane modes of crack deformation, the constant stress term T exists only in the presence of mode I. However, recent studies show that this term can exist inmode II conditions as well, and significantly affect the elastic stress field around the crack tip. These effects can be visualized using the experimental method of photoelasticity. Based on the analytical studies, presence of the T-stress in mode II cracks transforms the isochromatic fringe patterns from symmetric closed loops to asymmetric and discontinuous shapes. In this paper, presence of the T-stress in mode II cracks and its effects on the fringe patterns is experimentally investigated. The test specimens are Brazilian disks containing very sharp central cracks: experimental results indicate that these specimens contain negative values of T-stress. Experimental values are then compared to numerical results. To better understand the differences between experimental and numerical values, a thee dimensional analysis is performed with the finite element method: results show the influence of the real geometry of the crack front on the stress intensity factors.

    The use of social media has become commonplace in society. Consequently, many people living with chronic conditions are turning to social media applications to support self-management. This paper presents a formative non-exhaustive review of research literature regarding the role of social media for diabetes type II empowerment. In our review, we identified several major areas for diabetes health social media research, namely: a) social network data analytics, b) mHealth and diabetes, c) gamification for diabetes, c) wearable, and d) MOOCs (Massive Open Online Courses). In all these areas, we analyzed how social media is being used and the challenges emerging from its application in the diabetes domain.

    Researchers are increasingly using on line social networks to promote their work. Some authors have suggested that measuring social media activity can predict the impact of a primary study (i.e., whether or not an article will be highly cited). However, the influence of variables such as scientific quality, research disclosures, and journal characteristics on systematic reviews and meta-analyses has not yet been assessed. The present study aims to describe the effect of complex interactions between bibliometric factors and social media activity on the impact of systematic reviews and meta-analyses about psoriasis (PROSPERO 2016: CRD42016053181). Methodological quality was assessed using the Assessing the Methodological Quality of Systematic Reviews (AMSTAR) tool. Altmetrics, which consider Twitter, Facebook, and Google+ mention counts as well as Mendeley and SCOPUS readers, and corresponding article citation counts from Google Scholar were obtained for each article. Metadata and journal-related bibliometric indices were also obtained. One-hundred and sixty-four reviews with available altmetrics information were included in the final multifactorial analysis, which showed that social media and impact factor have less effect than Mendeley and SCOPUS readers on the number of cites that appear in Google Scholar. Although a journal's impact factor predicted the number of tweets (OR, 1.202; 95% CI, 1.087-1.049), the years of publication and the number of Mendeley readers predicted the number of citations in Google Scholar (OR, 1.033; 95% CI, 1.018-1.329). Finally, methodological quality was related neither with bibliometric influence nor social media activity for systematic reviews. In conclusion, there seems to be a lack of connectivity between scientific quality, social media activity, and article usage, thus predicting scientific success based on these variables may be inappropriate in the particular case of systematic reviews.

    To review how the media frames obesity and the effect it has upon on public perceptions. The scientific and public health understanding of obesity increasingly points away from individual behaviors and toward medical and community factors, but diffusion of this knowledge is slow. Growing awareness of the importance of body positivity is driving attention to the harms of weight bias and fat shaming. Health science reporting related to obesity, nutrition, and physical activity tends to perpetuate myths and misunderstandings. Moving forward, greater attention to accurate messages about obesity and evidence-based interventions will be essential for progress to reduce suffering and the impact on public health from this chronic disease.

    2017-02-01

    This qualitative study examined descriptions of social media use among 23 adolescents (18 female, 5 male) who were diagnosed with depression to explore how social media use may influence and be influenced by psychological distress. Adolescents described both positive and negative use of social media. Positive use included searching for positive content (i.e. for entertainment, humor, content creation) or for social connection. Negative use included sharing risky behaviors, cyberbullying, and for making self-denigrating comparisons with others. Adolescents described three types of use in further detail including "oversharing" (sharing updates at a high frequency or too much personal information), "stressed posting" (sharing negative updates with a social network), and encountering "triggering posts." In the context of treatment, these adolescents shifted their social media use patterns from what they perceived as negative to more positive use. Implications for clinicians counseling depressed adolescents on social media use are discussed. Copyright © 2016 The Foundation for Professionals in Services for Adolescents.

    Chitosan, CS was chemically engineered by maleic anhydride via simple protocol to produce N-maleated chitosan, MCS which immobilized on anatase TiO2 to synthesize novel eco-friendly nanosorbent (51 ± 3.8 nm), MCS@TiO2 for cost-effective and efficient removal of Pb(II) ions from aqueous media. The chemical structure, surface properties and morphology of MCS@TiO2 were recognized by FTIR, 1H NMR, XRD, TEM, DLS and zeta-potential techniques. The relations between %removal of Pb(II) and different analytical parameters such as solution acidity (pH), MCS@TiO2 dosage, time of contact and initial Pb(II) concentration were optimized using response surface methodology (RSM) and Box-Behnken design (BBD) statistical procedures. The fitting of the experimental data to four different isotherm models at optimized conditions was carried out by various statistical treatments including the correlation coefficient (r), coefficient of determination (r2) and non-linear Chi-square (χ2) test analyses which all confirm the suitability of Langmuir model to explain the adsorption isotherm data. Also, statistics predicted that the pseudo-second-order model is the optimum kinetic model among four applied kinetic models to closely describe the rate equation of the adsorption process. Thermodynamics viewed the adsorption as endothermic and feasible physical process. EDTA could release the sorbed Pb(II) ions from MCS@TiO2 with a recovery above 92% after three sorption-desorption cycles. The novel synthesized nanosorbent is evidenced to be an excellent solid phase extractor for Pb(II) ions from wastewaters.

    Regular breakfast and well-balanced soft drink, and screen media consumption are associated with a lower risk of overweight and obesity in schoolchildren. The aim of this research is the combined examination of these three parameters as influencing factors for longitudinal weight development in schoolchildren in order to adapt targeted preventive measures. In the course of the Baden-Württemberg Study, Germany, data from direct measurements (baseline (2010) and follow-up (2011)) at schools was available for 1733 primary schoolchildren aged 7.08 ± 0.6 years (50.8% boys). Anthropometric measurements of the children were taken according to ISAK-standards (International Standard for Anthropometric Assessment) by trained staff. Health and lifestyle characteristics of the children and their parents were assessed in questionnaires. A linear mixed effects regression analysis was conducted to examine influences on changes in waist-to-height-ratio (WHtR), weight, and body mass index (BMI) measures. A generalised linear mixed effects regression analysis was performed to identify the relationship between breakfast, soft drink and screen media consumption with the prevalence of overweight, obesity and abdominal obesity at follow-up. According to the regression analyses, skipping breakfast led to increased changes in WHtR, weight and BMI measures. Skipping breakfast and the overconsumption of screen media at baseline led to higher odds of abdominal obesity and overweight at follow-up. No significant association between soft drink consumption and weight development was found. Targeted prevention for healthy weight status and development in primary schoolchildren should aim towards promoting balanced breakfast habits and a reduction in screen media consumption. Future research on soft drink consumption is needed. Health promoting interventions should synergistically involve children, parents, and schools.

    Amy Jordan addresses the need to balance the media industry's potentially important contributions to the healthy development of America's children against the consequences of excessive and age-inappropriate media exposure. Much of the philosophical tension regarding how much say the government should have about media content and delivery stems from the U.S. Constitution's First Amendment protection against government interference in free speech, including commercial speech. Courts, Jordan says, have repeatedly had to weigh the rights of commercial entities to say what they please against the need to protect vulnerable citizens such as children. This balancing act is complicated even further, she says, because many government regulations apply only to broadcast television and not to non-broadcast media such as the Internet or cable television, though Congress has addressed the need to protect children's privacy online. The need to protect both free speech and children has given rise to a fluid media policy mix of federal mandates and industry self-regulation. Jordan describes the role of the three branches of the federal government in formulating and implementing media policy. She also notes the jockeying for influence in policymaking by industry lobbies, child advocacy groups, and academic researchers. The media industry itself, says Jordan, is spurred to self-regulation when public disapproval grows severe enough to raise the possibility of new government action. Jordan surveys a range of government and industry actions, from legislatively required parental monitoring tools, such as the V-Chip blocking device on television sets, to the voluntary industry ratings systems governing television, movies, and video games, to voluntary social website disclosures to outright government bans, such as indecency and child privacy information collection. She considers the success of these efforts in limiting children's exposure to damaging content and in improving parents

    Media interventions can potentially play a major role in influencing health policies. This integrative systematic review aimed to assess the effects of planned media interventions-including social media-on the health policy-making process. Eligible study designs included randomized and non-randomized designs, economic studies, process evaluation studies, stakeholder analyses, qualitative methods, and case studies. We electronically searched Medline, EMBASE, Communication and Mass Media Complete, Cochrane Central Register of Controlled Trials, and the WHO Global Health Library. We followed standard systematic review methodology for study selection, data abstraction, and risk of bias assessment. Twenty-one studies met our eligibility criteria: 10 evaluation studies using either quantitative (n = 7) or qualitative (n = 3) designs and 11 case studies. None of the evaluation studies were on social media. The findings of the evaluation studies suggest that media interventions may have a positive impact when used as accountability tools leading to prioritizing and initiating policy discussions, as tools to increase policymakers' awareness, as tools to influence policy formulation, as awareness tools leading to policy adoption, and as awareness tools to improve compliance with laws and regulations. In one study, media-generated attention had a negative effect on policy advocacy as it mobilized opponents who defeated the passage of the bills that the media intervention advocated for. We judged the confidence in the available evidence as limited due to the risk of bias in the included studies and the indirectness of the evidence. There is currently a lack of reliable evidence to guide decisions on the use of media interventions to influence health policy-making. Additional and better-designed, conducted, and reported primary research is needed to better understand the effects of media interventions, particularly social media, on health policy-making processes, and

    We investigated a unique way in which adolescent peer influence occurs on social media. We developed a novel functional MRI (fMRI) paradigm to simulate Instagram, a popular social photo-sharing tool, and measured adolescents' behavioral and neural responses to likes, a quantifiable form of social endorsement and potential source of peer influence. Adolescents underwent fMRI while viewing photos ostensibly submitted to Instagram. They were more likely to like photos depicted with many likes than photos with few likes; this finding showed the influence of virtual peer endorsement and held for both neutral photos and photos of risky behaviors (e.g., drinking, smoking). Viewing photos with many (compared with few) likes was associated with greater activity in neural regions implicated in reward processing, social cognition, imitation, and attention. Furthermore, when adolescents viewed risky photos (as opposed to neutral photos), activation in the cognitive-control network decreased. These findings highlight possible mechanisms underlying peer influence during adolescence. © The Author(s) 2016.

    Full Text Available Mass media is playing a significant role in influencing people’s mind and determining the vote’s preference of each single individual. Nowadays, mass media has become an essential part in setting up the public’s agenda. We are living in a social media era that is being governed by Facebook and Twitter. Facebook had played a key role in Germany’s society in the last year, since September 2015, by helping to increase public awareness or to collect opinions and information, and also to influence the attitude of the people towards electing the Eurosceptic political party, Alternative for Germany (AfD. The results of the regional elections in Germany from March 2016 had been strongly influenced by the party’s intense activities on Facebook. It may be said that the electoral campaign of AfD had completely taken place on Facebook, a social media channel where people and the party itself dare to speak up their mind without being afraid that their opinion could be censorship. This article is about to describe the role that the social media channel, Facebook, had had in choosing AfD as main winner of the German regional elections.

Digital technology continues to reshape the mass media landscape using internet technology. Internet brings a technical communication revolution, a fundamental change takes place in the structure of connections, artificial memories and the reproduction of their content. Internet technology has made communication much easier and less expensive. It has attracted many people and has penetrated into people’s daily lives. The mass media also have accepted the internet. Almost all forms of traditional media (old media in local media, such as radio, television, and newspaper have extended their work into this new field. The internet and the World Wide Web have both significantly influenced modern journalism. In online media allows readers to enjoy browsing their product and service of contents, such as news feed, podcasts, desktop alert, news on mobile phones, PDA and others mobile devices. Online media offer not only text but also digital images , audio file, moving images (video, internet radio and internet t v.

    We address multipole surface solitons occurring at the interface between a linear medium and a nonlocal nonlinear medium. We show the impact of nonlocality, the propagation constant, and the linear index difference of two media on the properties of the surface solitons. We find that there exist a threshold value of the degree of the nonlocality at the same linear index difference of two media, only when the degree of the nonlocality goes beyond the value, the multipole surface solitons can be stable. -- Highlights: ► We show the impact of nonlocality and the linear index difference of two media on the properties of the surface solitons. ► For the surface solitons, only when the degree of the nonlocality goes beyond a threshold value, they can be stable. ► The number of poles and the index difference of two media can all influence the threshold value.

  10. The drive for muscularity in men: media influences and objectification theory.

    Daniel, Samantha; Bridges, Sara K

    2010-01-01

    Presently, objectification theory has yielded mixed results when utilized to explain body image concerns in men. An online survey assessing internalization of media ideals, self-objectification, body surveillance, body shame, the drive for muscularity, and body mass index (BMI) was completed by 244 predominantly college-aged males. Path analyses were used to investigate relationships among these variables where it was hypothesized that objectification variables would mediate the relationship between internalization of media ideals and the drive for muscularity. Internalization of media ideals was the strongest predictor of the drive for muscularity, followed by BMI, though variables of objectification theory had no impact on the drive for muscularity contrary to hypotheses. The results suggest that objectification theory may not be applicable to men as it is currently measured. Copyright 2009 Elsevier Ltd. All rights reserved.

    2011-01-01

    Background Mass media exposure has been associated with an increased risk of eating pathology. It is unknown whether indirect media exposure – such as the proliferation of media exposure in an individual’s social network – is also associated with eating disorders. Aims To test hypotheses that both individual (direct) and social network (indirect) mass media exposures were associated with eating pathology in Fiji. Method We assessed several kinds of mass media exposure, media influence, cultural orientation and eating pathology by self-report among adolescent female ethnic Fijians (n = 523). We fitted a series of multiple regression models of eating pathology, assessed by the Eating Disorder Examination Questionnaire (EDE–Q), in which mass media exposures, sociodemographic characteristics and body mass index were entered as predictors. Results Both direct and indirect mass media exposures were associated with eating pathology in unadjusted analyses, whereas in adjusted analyses only social network media exposure was associated with eating pathology. This result was similar when eating pathology was operationalised as either a continuous or a categorical dependent variable (e.g. odds ratio OR = 1.60, 95% CI 1.15–2.23 relating social network media exposure to upper-quartile EDE–Q scores). Subsequent analyses pointed to individual media influence as an important explanatory variable in this association. Conclusions Social network media exposure was associated with eating pathology in this Fijian study sample, independent of direct media exposure and other cultural exposures. Findings warrant further investigation of its health impact in other populations. PMID:21200076

    Determine the incidence of ear infections in cochlear implant patients, evaluate the contribution of otitis media to complications, describe the bacteriology of otitis media in the cochlear implant population, the treatment provided at our center, and the long term outcome. Data collected included age at implantation, history of otitis media or ear tubes, etiology of hearing loss, inner ear anatomy, postoperative infections, time to infection, route of antibiotic administration, and interventions for infections. Categories of infection were acute otitis media, otitis media with effusion, tube otorrhea, meningitis, scalp cellulitis, and infection at the implant site. Middle ear infections were diagnosed in 37% of implanted ears. Extension of middle ear infections into the implant site occurred in 2.8% of all implants (n = 16). Of the 16 infected devices, 10 were successfully treated with antibiotic therapy and did not require explantation. The retained implant group and explanted group both included some middle ear microbes such as Haemophilus influenzae and Streptococcus pneumoniae, as well as skin flora such as Staphylococcus aureus. Otitis media in pediatric cochlear implant patients is a common event and usually does not lead to complications of the cochlear implant. However, when the ear infection spreads to the scalp and the implant site, it is still possible to eliminate the infection using antibiotic therapy, particularly when treatment is directed to the specific organism that is recovered from the infected space and the duration and route of antibiotic treatment is carefully considered.

    In two long-term studies, the BACTEC radiometric system for detection of bacteremia was evaluated with three culture media each: (i) BACTEC media 6A (for aerobes) and 7B (for anaerobes) plus a thioglycolate medium and (ii) BACTEC media 6A, 7B, and 8A (hypertonic). In study 1, clinically significant isolates were identified in 1,873 (13.9%) of 13,432 blood cultures with all three media. The thioglycolate medium revealed 143 (1.1%) organisms not recovered from the 6A and 7B media. In study 2, isolates were identified in 1,135 (12.9%) of 8,759 cultures with all three media; 104 (1.2%) organisms were isolated only from the hypertonic medium. The increased yield of positive cultures in the three-medium system is likely due to the larger volume of blood cultured

  19. Dog movie stars and dog breed popularity: a case study in media influence on choice.

    Directory of Open Access Journals (Sweden)

    Stefano Ghirlanda

    Full Text Available Fashions and fads are important phenomena that influence many individual choices. They are ubiquitous in human societies, and have recently been used as a source of data to test models of cultural dynamics. Although a few statistical regularities have been observed in fashion cycles, their empirical characterization is still incomplete. Here we consider the impact of mass media on popular culture, showing that the release of movies featuring dogs is often associated with an increase in the popularity of featured breeds, for up to 10 years after movie release. We also find that a movie's impact on breed popularity correlates with the estimated number of viewers during the movie's opening weekend--a proxy of the movie's reach among the general public. Movies' influence on breed popularity was strongest in the early 20th century, and has declined since. We reach these conclusions through a new, widely applicable method to measure the cultural impact of events, capable of disentangling the event's effect from ongoing cultural trends.

  20. Examining How Media Literacy and Personality Factors Predict Skepticism Toward Alcohol Advertising.

    Austin, Erica Weintraub; Muldrow, Adrienne; Austin, Bruce W

    2016-05-01

    To examine the potential effectiveness of media literacy education in the context of well-established personality factors, a survey of 472 young adults, focused on the issue of alcohol marketing messages, examined how individual differences in personality associate with constructs representing aspects of media literacy. The results showed that need for cognition predicted social expectancies and wishful identification with media portrayals in alcohol advertising only through critical thinking about media sources and media content, which are foci of media literacy education. Need for affect did not associate with increased or diminished levels of critical thinking. Critical thinking about sources and messages affected skepticism, represented by expectancies through wishful identification, consistent with the message interpretation process model. The results support the view that critical thinking about media sources is an important precursor to critical thinking about media messages. The results also suggest that critical thinking about media (i.e., media literacy) reflects more than personality characteristics and can affect wishful identification with role models observed in media, which appears to be a key influence on decision making. This adds support to the view that media literacy education can improve decision making across personality types regarding alcohol use by decreasing the potential influence of alcohol marketing messages.
