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 We live in times of rapid change in all areas of science, technology, communication and social life. Every day we are asked to what extent school prepares us for these changes and for life in a new, multimedia environment. Children and adolescents spend less time at school or in other settings of learning than they do outdoors or within other social communities (family, clubs, societies, religious institutions and the like. Experts must constantly inquire about what exactly influences learning and development in our rich media environment. The list of the most important life competences has significantly changed and expanded since the last century. Educational experts are attempting to predict changes in the content and methodology of learning at the beginning of the 21st century. Answers are sought to key questions such as: what should one learn; how should one learn; where should one learn; why should one learn; and how do these answers relate to the new learning environment? In his examination of the way children and young people learn and grow up, the author places special attention on the relationship between personal and non-personal communication (e.g. the internet, mobile phones and different types of e-learning. He deals with today's questions by looking back to some of the more prominent authors and studies of the past fifty years that tackled identical or similar questions (Alvin Toffler, Ivan Illich, George Orwell, and the members of the Club of Rome. The conclusion reached is that in today's world of rapid and continuous change, it is much more crucial than in the last century, both, to be able to learn, and to adapt to learning with the help of new media.

United States news media and climate change in the era of US President Trump.

Science.gov (United States)

Park, David J

2018-03-01

The Donald J Trump administration's strategy to disengage and downplay the Paris Climate Agreement will likely result in a slight decrease in the already low levels of US news media global warming coverage. This is because significant limitations with the news media's ability to adequately cover climate change predated the administration. First, studies indicate that advertising interests and editors have always challenged journalists' abilities to adequately report on climate change issues. Instead of climate change stories, editors often prefer more sensational topics that garner higher ratings and approval with advertisers. Second, the journalistic norm of balance and the role of sourcing give climate skeptics exceptional media exposure, which creates a "false balance" or equivalency between skeptics and scientists. Third, the massive power and influence of the fossil fuel industry's public relations arm has also had a tremendous impact on public (mis)understanding of climate change. Fourth, a trend toward declining climate change coverage and "climate silence" in US media is developing. Media corporations have substantially eliminated the number of environmental journalists that cover climate change. The overall effect of these limitations distorts public understanding of climate change and delays potential government action. Moving away from a predominantly commercial media system to one with a substantial noncommercial component can improve US journalism, whereas using advertising to increase rates for environmentally unsound products and services may also help mitigate global warming.

Detecting Rumors Through Modeling Information Propagation Networks in a Social Media Environment.

Science.gov (United States)

Liu, Yang; Xu, Songhua; Tourassi, Georgia

2015-01-01

In the midst of today's pervasive influence of social media content and activities, information credibility has increasingly become a major issue. Accordingly, identifying false information, e.g. rumors circulated in social media environments, attracts expanding research attention and growing interests. Many previous studies have exploited user-independent features for rumor detection. These prior investigations uniformly treat all users relevant to the propagation of a social media message as instances of a generic entity. Such a modeling approach usually adopts a homogeneous network to represent all users, the practice of which ignores the variety across an entire user population in a social media environment. Recognizing this limitation of modeling methodologies, this study explores user-specific features in a social media environment for rumor detection. The new approach hypothesizes that whether a user tends to spread a rumor is dependent upon specific attributes of the user in addition to content characteristics of the message itself. Under this hypothesis, information propagation patterns of rumors versus those of credible messages in a social media environment are systematically differentiable. To explore and exploit this hypothesis, we develop a new information propagation model based on a heterogeneous user representation for rumor recognition. The new approach is capable of differentiating rumors from credible messages through observing distinctions in their respective propagation patterns in social media. Experimental results show that the new information propagation model based on heterogeneous user representation can effectively distinguish rumors from credible social media content.

Corrosive environment tester for filter media

International Nuclear Information System (INIS)

Petit, G.S.; Weber, C.W.; Keinberger, C.A.; Rivers, R.D.

1977-02-01

Two continuous dynamic systems have been designed and fabricated for testing filter media in humid, corrosive environments--one for fluorine or fluoride exposures, and the other for nitrogen dioxide exposures. The tester using fluorine or fluoride atmospheres was constructed of nickel and the one using nitrogen dioxide was fabricated of stainless steel. Other corrosive gases could be used with the appropriate choice of system. For example, chlorine or hydrogen chloride could be used in the system fabricated of nickel, and sulfur dioxides or ammonia could be used in the stainless steel testing apparatus. Each tester is comprised of four equivalent dynamic systems designed for diluting a corrosive reagent with dry air, then with humidified air to provide a humid-corrosive environment for filter media testing. Auxiliary equipment includes a water injection system, corrosive reagent supply systems, and an automatic pressure differential (ΔP) monitoring and recording system. The testers are relatively maintenance-free and have operated continuously for periods as long as 96 h without requiring any attention, during total exposures of materials exceeding 600 h

Engagement in social media environments for individuals with who use augmentative and alternative communication.

Science.gov (United States)

Caron, Jessica

2016-10-14

Communicative interactions, despite the mode (e.g., face-to-face, online) rely on the communication skills of each individual participating. Some individuals have significant speech and language impairments and require the use of augmentative and alternative communication (AAC) (i.e., signs, speech generating devices) to maximize their communication participation across a variety of on and offline contexts. Use of social media has brought about changes to communication environments, contributing new contexts for engagement. To provide a framework for considering application of engagement theory for interventions around social media use by individuals who use AAC. The author has applied examples from qualitative social media and AAC research to a framework of engagement. No formal data collection was used. Social media use has become a conventional form of communication. Yet recognition of the value of social media (and other electronic modalities) for individuals who use AAC has not been fully translated into practice. The examples used illustrated how the proposed framework can assist in clinical practice and future research directions. Engagement, including the proposed framework for considerations of social media engagement activities, can provide a systematic way to approach social media use for individuals who use AAC.

Generating news media interest in tobacco control; challenges in an advanced policy environment.

Science.gov (United States)

MacKenzie, Ross; Chapman, Simon

2012-08-01

To determine the efficacy of using media releases for tobacco control advocacy in Australia's advanced policy environment. Between February and August 2010, news releases that summarised either newly published but unpublicized research findings, or local developments in tobacco control, were sent to NSW media outlets. Reports arising from the releases were tracked using commercial services Media Monitors and Factiva, as well as Google and Google News. Other tobacco control related news items during the same period were also tracked and recorded. Twenty-one news releases generated 93 news items across all news media, with a quarter of these related to a story of porcine haemoglobin in cigarette filters. By comparison, 'live' policy issues (especially plain packaging and a significant tobacco tax increase) covered in this period attracted 1,033 news stories in the Australian media. Press releases describing recently published, but underpublicized research were issued in weeks where no major competing tobacco control news occurred. Results of this project indicate that in environments with advanced tobacco policy, media opportunities related to tobacco control advocacy are limited, as many objectives have been achieved. The media can still play a key advocacy role in such environments, and advocates need to be particularly vigilant for opportunities that do arise. The paper also highlights the increasingly important role of internet-based media, including opportunities presented by social media for tobacco control.

Integrating Media Production By Students Into Climate Change Education: Within and Beyond the Classroom

Rooney-Varga, J. N.; Brisk, A. A.; Grogan, M.; Ledley, T. S.

2012-12-01

Through the Climate Education in an Age of Media (CAM) Project (http://cleanet.org/cced_media/), we have developed approaches to integrate media production by students into climate change education in ways that are engaging, empowering, and can be readily adopted in a wide range of instructional environments. These approaches can be used to overcome many of the challenges that climate change education presents and provide a means to evoke experiential, affective, and social learning pathways. Video production combines many key twenty-first century literacy skills, including content research, writing, an understanding of the power of images and sounds, the ability to use that power, and the ability to manipulate, transform, and distribute digital media. Through collaboration, reflection, and visual expression of concepts, video production facilitates a deeper understanding of material and, potentially, shifts in mental models about climate change. Equally importantly, it provides a means to bridge formal and informal learning by enabling students to educate those beyond the classroom. We have piloted our approach in two intensive summer programs (2011 and 2012) for high school students, during which students learned about climate change science content in lessons that were paired with the production of short media pieces including animations, public service announcements, person-on-the-street interviews, mock trailers, mock news programs, and music videos. Two high school teachers were embedded in the program during the second year, providing feedback and assessment of the feasibility, accessibility, and utility of the approach. The programs culminated with students presenting and discussing their work at public screening events. The media lessons and climate change science content examples used in these programs form the backbone of a toolkit and professional development workshops for middle and high school teachers, in which teachers learn how to incorporate

Screen-viewing time has been associated with adverse health outcomes. Data on the predictors of youth screen-viewing time is predominately from older children in North America. Parental and home media environment factors that are associated with screen-viewing time could be targeted in interventions. Examine if parental screen-viewing time and electronic media (access to game equipment, TVs, PCs, and laptops) environment factors were associated with Portuguese children's screen-viewing time and if associations differed by child age (families with children aged 3-10 years. Data were collected in 2009-2010 and analyzed in 2011. Outcomes were child spending ≥2 hours watching TV and ≥1 hour per day playing with combined other media. Exposures were mothers and fathers watching ≥2 hours of TV and electronic media variables. Parental TV-viewing time was strongly associated with child weekday and weekend TV-viewing time across all four gender and age subgroups. Maternal TV-viewing time was a stronger predictor of child TV-viewing time than paternal TV-viewing time. There was very limited evidence that parental TV-viewing time was associated with combined other media time among boys or girls. Access to electronic game equipment increased the likelihood that children spent >1 hour using combined other media on weekdays and weekend days. Parental TV-viewing time was associated with Portuguese children's TV-viewing time. The numbers of TVs in the household and electronic games equipment access were also associated with TV- and combined other media-viewing/usage time.

Full Text Available Digitalization of the mass media, which has radically changed the information environment, creates new opportunities for self-education and upgrowth of the audience. The paper defines the communicative and cultural status of new media, characterizes the socio-cultural and technological aspects of their dynamics; substantiates the necessity of elaborating mechanisms for systematization of heterogeneous information flows and elaborating criteria for their evaluation in the era of globalization of the media sphere, what implies a qualitatively different level of media competence of the audience, provided with such factors as media education, media coverage, media criticism. The definition of concepts "media competence", "media enlightenment", "media education", "media criticism" is given and their functional areas are delineated. Social networks are considered as an important tool for media enlightenment which provides significant opportunities for promoting cultural achievements in the new media environment.

Contrast media osmolality and plasma volume changes

International Nuclear Information System (INIS)

Hine, A.L.; Lui, D.; Dawson, P.; Middlesex Hospital, London

1985-01-01

A theoretical and experimental study of the plasma volume expansion consequent on the hyperosmolality of contrast media is presented. In the case of the ratio 1.5 media theory and experiment coincide closely but in the case of the ratio 3 media the observed changes exceed the predicted. It is proposed that this is due partly to the slower diffusion of the ratio 3 media out of the intravascular space and partly due to the fact that the osmotic load presented by these media is greater than would be expected from a study of their commercial solutions in which osmolality is reduced by molecular aggregation. The implications for the relative haemodynamic effects of different contrast media are discussed. The osmotic effects of contrast media also play a part in determining the image quality achievable in intravenous digital subtraction angiography (IV-DSA). It is predicted that ratio 3 contrast media will give better quality images in IV-DSA than ratio 1.5 media. (orig.)

Variants of Interplay as Drivers of Media Change

Directory of Open Access Journals (Sweden)

Tilo Grenz

2017-09-01

Full Text Available This article conceptualizes acting on media in terms of different interplays between focal actors, users, and user communities. It is argued that—in times of mediated visibility, the increasing entanglement of social and technological change, and accelerated feedback loops—arenas of negotiation emerge and therewith the complexities of relations between producers and users increases. Using insights from the fields of Wii hacking, Circuit Bending, and online poker tools, three variants of interplay are presented and discussed: integration, segregation, and permanent confrontation. Whilst a process-oriented perspective on reciprocal action is developed the paper contributes (a to a balanced perspective on what is often a one-sided discussion regarding the actions leading to media change, and (b to the understanding of the relation between media change and reflexive modernity.

Meta-media and meta-communication - Revisiting the concept of genre in the digital media environment

Directory of Open Access Journals (Sweden)

Klaus Bruhn Jensen

2011-08-01

Full Text Available As analytical categories, genres have traditionally occupied a middle ground – between media as technologies and institutions, on the one hand, and discourses as material and modal forms of expression and interaction, on the other. With digitalization, the very concept of genre is in doubt: is the world wide web, Facebook, or the writing on its walls the genre? This article situat es genre in relation to the concepts of meta-media and meta-communication. First, I characterize the computer and the internet as metamedia, incorporating previous genres of embodied communication as well as mass communication. Second, I describe genres as a variety of meta-communication, which serves to configure communication in the first place. In conclusion, I discuss whether and how a category of meta-genres might help to account for some distinctive features of the digital media environment.

Use of mass media campaigns to change health behaviour.

Science.gov (United States)

Wakefield, Melanie A; Loken, Barbara; Hornik, Robert C

2010-10-09

Mass media campaigns are widely used to expose high proportions of large populations to messages through routine uses of existing media, such as television, radio, and newspapers. Exposure to such messages is, therefore, generally passive. Such campaigns are frequently competing with factors, such as pervasive product marketing, powerful social norms, and behaviours driven by addiction or habit. In this Review we discuss the outcomes of mass media campaigns in the context of various health-risk behaviours (eg, use of tobacco, alcohol, and other drugs, heart disease risk factors, sex-related behaviours, road safety, cancer screening and prevention, child survival, and organ or blood donation). We conclude that mass media campaigns can produce positive changes or prevent negative changes in health-related behaviours across large populations. We assess what contributes to these outcomes, such as concurrent availability of required services and products, availability of community-based programmes, and policies that support behaviour change. Finally, we propose areas for improvement, such as investment in longer better-funded campaigns to achieve adequate population exposure to media messages. Copyright © 2010 Elsevier Ltd.

Full Text Available In this paper we intend to describe the economic implications of mass-media in correlation with the recent socio-economic changes generated by the economic crisis. We take into consideration the dual market on which mass-media evolves: the mass-media products market, and the advertising market, keeping in mind that the behavior of a mass-media institution on one market, can have direct implication on the other market. We analyze the relation between mass-media and the public (audience, the cost for creating mass-media products, the ways in which mass-media reduces costs and the ways of increasing their profits. As mass-media must always adapt to the social changes and to the public, we take our analysis further and we describe how the recent economic changes influenced the mass-media consumption trends and mass-media profits on all the main communication channels: TV, radio, outdoor, internet, newspapers/magazines. This analysis is performed at both a global and a local level, for Romania. In the end we predict how other key changes may affect the economic model approach of the mass-media institutions on short and middle terms.

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.)

Hemodynamic and tubular changes induced by contrast media.

The incidence of acute kidney injury induced by contrast media (CI-AKI) is the third cause of AKI in hospitalized patients. Contrast media cause relevant alterations both in renal hemodynamics and in renal tubular cell function that lead to CI-AKI. The vasoconstriction of intrarenal vasculature is the main hemodynamic change induced by contrast media; the vasoconstriction is accompanied by a cascade of events leading to ischemia and reduction of glomerular filtration rate. Cytotoxicity of contrast media causes apoptosis of tubular cells with consequent formation of casts and worsening of ischemia. There is an interplay between the negative effects of contrast media on renal hemodynamics and on tubular cell function that leads to activation of renin-angiotensin system and increased production of reactive oxygen species (ROS) within the kidney. Production of ROS intensifies cellular hypoxia through endothelial dysfunction and alteration of mechanisms regulating tubular cells transport. The physiochemical characteristics of contrast media play a critical role in the incidence of CI-AKI. Guidelines suggest the use of either isoosmolar or low-osmolar contrast media rather than high-osmolar contrast media particularly in patients at increased risk of CI-AKI. Older age, presence of atherosclerosis, congestive heart failure, chronic renal disease, nephrotoxic drugs, and diuretics may multiply the risk of CI-AKI.

For researchers, being reported by mass media is an effective way to share their studies with others, although some have concerns that scientific results are often exaggerated by highlighting sensational parts and ignoring essential results by the media. Obviously, journalists have their own criteria of effective science reporting for their newspapers or magazines which do not necessarily conform to how researchers report their results. Climate Change Media Forum was started in 2009 by researchers specializing in climate science and communication to fill such gaps and enhance communication between climate scientists and journalists as part of a climate change research project funded by the Ministry of Environment of Japan. Since its start, forum events have been held once a year to exchange ideas on reporting of climate change science through mass media. At the first event in March, 2009, we started with learning about what actually the journalists and researchers think about media reports on climate change sciences. Using onsite questionnaire surveys, the participants (39 journalists and 31 researchers) discussed their problems on reporting climate change and what they would like to tell to the public. Some of the survey results suggested that researchers are willing to emphasize more about the conditions and assumptions of studies, while journalists would like to know more about current and short-term impacts. From the second year, two journalists joined the committee to make the events more meaningful for journalists. For the event in March, 2010, three months after COP15 in Copenhagen, the 2 degrees temperature target, which was the only written number on the Copenhagen Accord, was selected as a timely topic. Although researchers understand that a specific target is necessary for setting a concrete pathway, many of them also feel uncomfortable about selecting one single value from the temperature range with uncertainty. After two lectures on the history of the

Media reporting of clinical trials impacts patient-oncologist interactions. We sought to characterize the accuracy of media and Internet reporting of practice-changing clinical trials in oncology. The first media articles referencing 17 practice-changing clinical trials were collected from 4 media outlets: newspapers, cable news, cancer websites, and industry websites. Measured outcomes were media reporting score, social media score, and academic citation score. The media reporting score was a measure of completeness of information detailed in media articles as scored by a 15-point scoring instrument. The social media score represented the ubiquity of social media presence referencing 17 practice-changing clinical trials in cancer as determined by the American Society of Clinical Oncology in its annual report, entitled Clinical Cancer Advances 2012; social media score was calculated from Twitter, Facebook, and Google searches. The academic citation score comprised total citations from Google Scholar plus the Scopus database, which represented the academic impact per clinical cancer advance. From 170 media articles, 107 (63%) had sufficient data for analysis. Cohen's κ coefficient demonstrated reliability of the media reporting score instrument with a coefficient of determination of 94%. Per the media reporting score, information was most complete from industry, followed by cancer websites, newspapers, and cable news. The most commonly omitted items, in descending order, were study limitations, exclusion criteria, conflict of interest, and other. The social media score was weakly correlated with academic citation score. Media outlets appear to have set a low bar for coverage of many practice-changing advances in oncology, with reports of scientific breakthroughs often omitting basic study facts and cautions, which may mislead the public. The media should be encouraged to use a standardized reporting template and provide accessible references to original source

Full Text Available Abstract Background Little is known about how the home environmental supports physical activity and screen media usage. The purpose of this study was to develop and test the reliability and validity of a self-report instrument to comprehensively reflect the availability and accessibility of physical activity and screen media equipment in the home environment. Methods Ten families participated in the initial field testing to provide feedback for instrument development. Thirty one adult participants, each of whom had at least one child 10–17 years old, completed two Physical Activity and Media Inventory (PAMI instruments. The first PAMI was completed simultaneously, but independently, with a research assistant to assess validity. A second PAMI was completed by the participant one week later to assess reliability. Results The adult participants were mostly mothers/female guardians, mean age 38 ± 7.2 years, mostly Caucasian (52%, college educated (65%, living in single family homes (74%. Test-retest reliability was acceptable to strong for all summary variables (physical activity equipment, ICC = 0.76 to 0.99; media equipment, ICC = 0.72 to 0.96. For validation, reports from participants and research assistants were strongly correlated (physical activity, 0.67 – 0.98; media, 0.79 – 0.96. Compared to participants, research assistants reported a greater percentage of physical activity equipment as "in plain view and easy to get to" and a smaller percentage of items as "put away and difficult to get to". Conclusion Our results indicate strong evidence for the reliability and validity of the variables calculated from the PAMI. This self report inventory may be useful in assessing the availability of physical activity and screen media equipment in the home environment and could be used in conjunction with other home assessment tools (food availability, parenting styles and feeding practices to identify obesogenic home environments.

Communal farming, climate change adaptation and the media in Zimbabwe

Full Text Available Climate change is destroying Zimbabwean communal farmers’ agricultural activities – a source of living for most people. As communal farmers struggle to adapt, the media is expected to assume a fundamental theoretical role of educating and informing them about the appropriate adaptation techniques. Located in Umguza District in Matabeleland North Province, the study explored how communal farmers created meaning out of climate change media content and its influence on their agricultural practices from October 2014 to April 2015. In doing so, the study used the Two-Step Flow theory and Hall’s Encoding and Decoding Model. Entrenched in pragmatism, the study embedded quantitative techniques at different stages. Multistage sampling combining Simple Random Sampling (SRS, purposive and systematic sampling techniques was used to identify the 263 households for semi structured questionnaires, direct observations and in-depth interviews. The findings were analysed using Statistical Package for the Social Sciences (SPSS, thematic analysis and pattern matching. The results show that personal observations; print, broadcast and online media; and opinion leaders were the main sources of climate change information. The radio was the most used medium in communicating climate change adaptation though it was the second most accessed after mobile phones. Conservation Agriculture and planting of drought-resistant crops were some of the adaptation techniques communicated in the media. When interacting with media content, communal farmers create their own meaning influenced by their cultural values, resulting in some adopting, rejecting or modifying certain adaptation techniques. The study concludes that opinion leaders are fundamental in communal farmers’ interaction with media but their influence must not be overestimated.

Our House Is Burning: Discrepancy in Climate Change vs. Biodiversity Coverage in the Media as Compared to Scientific Literature

2018-01-01

Full Text Available Scientists, policy makers, and journalists are three key, interconnected players involved in prioritizing and implementing solutions to mitigate the consequences of anthropogenic pressures on the environment. The way in which information is framed and expertise is communicated by the media is crucial for political decisions and for the integrated management of environmental issues. Here we present a comparative study of scientific literature and press articles addressing climate change and biodiversity. We extensively scrutinized the scientific literature, research funding, and press articles from the USA, Canada, and United Kingdom addressing climate change and biodiversity issues between 1991 and 2016. We found that media coverage of climate change was up to eight times higher compared to biodiversity. This discrepancy could not be explained by different scientific output between the two issues. Moreover, climate change media coverage was often related to specific events whereas no such indication of a connection was found in the case of biodiversity. An international communication strategy is urgently required to raise public awareness on biodiversity issues. We discussed several initiatives that scientists could undertake to better communicate major discoveries to the public and policy makers.

Fukushima effects in Germany? Changes in media coverage and public opinion on nuclear power.

Arlt, Dorothee; Wolling, Jens

2016-10-01

Based on a literature review on factors that explain media effects and previous findings on media coverage and public opinion on nuclear power, this article examines the effects of Fukushima on media coverage and public opinion in Germany in two studies. The first study uses content analysis data to analyse changes in media coverage, and the second one is based on panel survey data to examine attitude changes on an individual level. The results of both studies show changes in media coverage and public opinion on nuclear power. Furthermore, the second study reveals that individual attitude changes cannot necessarily be explained by the same factors as the distribution of attitudes. © The Author(s) 2015.

Van den Bulck, Jan

2010-12-01

The media are an important part of young people's lives, but television, computer games, Internet use, cellular phone use, and even book reading threaten healthy sleep. Adults do not fully comprehend the ways in which young people use various media. Media use is a type of behavior that may displace sleep time or shorten it. Media content may lead to overexcitement or cause recurring nightmares. The cellular telephone is a particular threat. Parents may also use media excessively, establishing an unhealthy environment that may lead to sleep dysfunction in children and adolescents. Therefore, anticipatory guidance for healthy behavioral changes should be focused on the family.

The Role of the Media in the Construction of Public Belief and Social Change

Directory of Open Access Journals (Sweden)

Catherine Happer

2013-12-01

Full Text Available The media play a central role in informing the public about what happens in the world, particularly in those areas in which audiences do not possess direct knowledge or experience. This article examines the impact the media has in the construction of public belief and attitudes and its relationship to social change. Drawing on findings from a range of empirical studies, we look at the impact of media coverage in areas such as disability, climate change and economic development. Findings across these areas show the way in which the media shape public debate in terms of setting agendas and focusing public interest on particular subjects. For example, in our work on disability we showed the relationship between negative media coverage of people on disability benefit and a hardening of attitudes towards them. Further, we found that the media also severely limit the information with which audiences understand these issues and that alternative solutions to political problems are effectively removed from public debate. We found other evidence of the way in which media coverage can operate to limit understanding of possibilities of social change. In our study of news reporting of climate change, we traced the way that the media have constructed uncertainty around the issue and how this has led to disengagement in relation to possible changes in personal behaviours. Finally, we discuss the implications for communications and policy and how both the traditional and new media might help in the development of better informed public debate.

The environment in the headlines. Newspaper coverage of climate change and euthropication in Finland

Energy Technology Data Exchange (ETDEWEB)

Lyytimaeki, J.

2009-07-01

Media representations are an important part of the dynamics of contemporary socio-ecological systems. The media agenda influences and interacts with the public and the policy agenda and all of these are connected to the changes of the state of the environment. Partly as a result of media debate, some issues are considered serious environmental problems, some risks are amplified while others are attenuated, and some proposals for remedies are highlighted and others downplayed. Research on environmental media coverage has focused predominantly on the English-speaking industrialised countries. This thesis presents an analysis of Finnish environmental coverage, focusing on representations of climate change and eutrophication from 1990- 2010. The main source of material is Helsingin Sanomat (HS), the most widely-read newspaper in Finland. The analysis adopts the perspective of contextual constructivism and the agenda-setting function of the mass media. Selected models describing the evolution of environmental coverage are applied within an interdisciplinary emphasis. The results show that the amount of newspaper content on eutrophication and climate change has generally increased, although both debates have been characterised by intense fluctuations. The volume of the coverage on climate change has been higher than that of eutrophication, especially since 2006. Eutrophication was highlighted most during the late 1990s while the peaks of climate coverage occurred between 2007 and 2009. Two key factors have shaped the coverage of eutrophication. First, the coverage is shaped by ecological factors, especially by the algal occurrences that are largely dependent on weather conditions. Second, the national algal monitoring and communication system run by environmental authorities has provided the media with easy-to-use data on the algal situation during the summertime. The peaks of climate coverage have been caused by an accumulation of several contributing factors. The two

Many people consider strategic framing, the journalistic tendency to reduce politics to a game or competition focused on the tactical maneuvers of political actors, to be harmful to democracy because it erodes citizen interest in the democratic process. Our results demonstrate that this is not always the case. Testing the effects of textual strategic frames and video processing in a digital environment, we show that strategic frames may also provide a context that is more conducive to learning in mixed media news environments than that provided by value frames, those focused on the value conflict between principled policy opponents. Further analysis reveals that this effect is most clearly seen among people who read political blogs (i.e., those who are already active and interested in politics). Our data suggest that for individuals with cognitive networks built around ideological concerns, such as blog readers, value-framed messages provide cues to stop encoding new information, while strategically framed messages lead people to continue absorbing and learning in mixed media environments.

An increasing number of citizens change and adapt their party preferences during the electoral campaign. We analyze which short-term factors explain intra-campaign changes in voting preferences, focusing on the visibility and tone of news media reporting and party canvassing. Our analyses rely on an integrative data approach, linking data from media content analysis to public opinion data. This enables us to investigate the relative impact of news media reporting as well as party communication. Inherently, we overcome previously identified methodological problems in the study of communication effects on voting behavior. Our findings reveal that campaigns matter: Especially interpersonal party canvassing increases voters’ likelihood to change their voting preferences in favor of the respective party, whereas media effects are limited to quality news outlets and depend on individual voters’ party ambivalence.

Changes induced by metamedia - the internet is changing the position of the media market and the fundamental role of journalism. In response to these challenges in the U.S. several years ago began to develop the concept of "entrepreneurial journalism" that is still relatively unknown in the European public. Computers write news for, and artificial-intelligence experts at Google, predict that by of 2029. PCs to be smarter than the people, that in the next 15 years become more and more intelligent and will be able to understand what you 're talking about, learn from experience, they joke, tell stories, and even flirt. Journalism still has not found the outlines of his new identity, but it partly determines the logic of speed, brevity and superficiality of competition. The role of the editor is changing drastically - the editor should develop a vision angle and create an environment of different specialists who will thoughtfully implement it in practice. To have a greater effect on advertisers, journalists and editors are expected to not act in isolation in relation to the media business, and they know the mechanisms that determine whether and how advertisers appear within the online media. Respecting editorial integrity, journalists are the ones who should influence the greater engagement of readers. New professions in mediasfera is the creator of Content Curation, which are of great use journalistic and editorial experience. Computer - mediated communication replaces the actual communication and the media no longer represent reality but create it. In such circumstances, the media are no longer defined by their monopolistic or oligopolistic status, but their position in the market is determined to create their own identity in the online environment without

Contextual factors can influence health through exposures to health-promoting and risk-inducing factors. The aim of this study was to (1) build, from geotagged Twitter and Yelp data, a national food environment database and (2) to test associations between state food environment indicators and health outcomes. This is a cross-sectional study based upon secondary analyses of publicly available data. Using Twitter's Streaming Application Programming Interface (API), we collected and processed 4,041,521 food-related, geotagged tweets between April 2015 and March 2016. Using Yelp's Search API, we collected data on 505,554 unique food-related businesses. In linear regression models, we examined associations between food environment characteristics and state-level health outcomes, controlling for state-level differences in age, percent non-Hispanic white, and median household income. A one standard deviation increase in caloric density of food tweets was related to higher all-cause mortality (+46.50 per 100,000), diabetes (+0.75%), obesity (+1.78%), high cholesterol (+1.40%), and fair/poor self-rated health (2.01%). More burger Yelp listings were related to higher prevalence of diabetes (+0.55%), obesity (1.35%), and fair/poor self-rated health (1.12%). More alcohol tweets and Yelp bars and pub listings were related to higher state-level binge drinking and heavy drinking, but lower mortality and lower percent reporting fair/poor self-rated health. Supplemental analyses with county-level social media indicators and county health outcomes resulted in finding similar but slightly attenuated associations compared to those found at the state level. Social media can be utilized to create indicators of the food environment that are associated with area-level mortality, health behaviors, and chronic conditions.

It has been known that alteration in blood pressure, heart rate and other systemic reactions can occur after introduction of contrast media into the vascular system. And the factory of these alterations are the sudden changes of the circulating blood volume, hypertonicity of the injected contrast media and adverse reactions to the contrast media. This prospective study included evaluations of the hemodynamic changes, adverse reactions and its relationship with sensitivity test and allergic history in 105 patients who had been performed angiocardiography during the period of 1 year from October, 1981 to September, 1982. The results were as follows: 1. 14 out of 105 patient showed minor reactions to contrast media such as nausea, vomiting , coughing, etc. There is no close relationship between adverse reaction and sensitivity test or previous allergic history. 2. In the group of right sided angiocardiography, 47.6% of patient showed elevation of blood pressure after injection of contrast media. 38.1% of patient, however, showed lowered blood pressure. The changes of the pulse rate were quite similar to those of blood pressure; increased in 47.7% and decreased in 40.9% of patient. 3. In the group of left sided angiocardiography, 61.6% of patient showed elevation of blood pressure immediately after injection of contrast media, and 17.5% of patient showed lowered blood pressure. 5 minutes after injection of contrast media, large group of patient showed normalized blood pressure. The pulse ratio was also increased in the 66.3% of patient

Media can influence aspects of a child's physical, social, and cognitive development; however, the associations between a child's household media environment, media use, and academic achievement have yet to be determined. To examine relationships among a child's household media environment, media use, and academic achievement. During a single academic year, data were collected through classroom surveys and telephone interviews from an ethnically diverse sample of third grade students and their parents from 6 northern California public elementary schools. The majority of our analyses derive from spring 2000 data, including academic achievement assessed through the mathematics, reading, and language arts sections of the Stanford Achievement Test. We fit linear regression models to determine the associations between variations in household media and performance on the standardized tests, adjusting for demographic and media use variables. The household media environment is significantly associated with students' performance on the standardized tests. It was found that having a bedroom television set was significantly and negatively associated with students' test scores, while home computer access and use were positively associated with the scores. Regression models significantly predicted up to 24% of the variation in the scores. Absence of a bedroom television combined with access to a home computer was consistently associated with the highest standardized test scores. This study adds to the growing literature reporting that having a bedroom television set may be detrimental to young elementary school children. It also suggests that having and using a home computer may be associated with better academic achievement.

Climate change on Twitter: Content, media ecology and information sharing behaviour.

Veltri, Giuseppe A; Atanasova, Dimitrinka

2017-08-01

This article presents a study of the content, use of sources and information sharing about climate change analysing over 60,000 tweets collected using a random week sample. We discuss the potential for studying Twitter as a communicative space that is rich in different types of information and presents both new challenges and opportunities. Our analysis combines automatic thematic analysis, semantic network analysis and text classification according to psychological process categories. We also consider the media ecology of tweets and the external web links that users shared. In terms of content, the network of topics uncovered presents a multidimensional discourse that accounts for complex causal links between climate change and its consequences. The media ecology analysis revealed a narrow set of sources with a major role played by traditional media and that emotionally arousing text was more likely to be shared.

Devotta, Kimberly; Wilton, Robert; Yiannakoulias, Niko

2013-01-01

To assess stability and change in representations of disability and persons with disability in the Canadian news media between 1998 and 2008. The study replicated research conducted in 1998 that assessed the representation of disability in the Canadian news media. Following the earlier study, three newspapers were selected (Globe and Mail, Toronto Star and Toronto Sun) and all articles from a three-month period in 1998 and 2008 were assessed for disability content. In total, 362 articles were found in the two time periods. These were coded for structure and content using a schema developed in the earlier research. Between 1998 and 2008, there was a significant increase in the proportion of stories using "person first" language, and a significant increase in the proportion of "progressively" themed articles (e.g. dealing with barriers to participation, or disability awareness and inclusion). At the same time, there were significant differences between newspapers, with the Toronto Sun (a tabloid) maintaining a strong focus on "traditional" themes (e.g. special education, charitable provision). The differences in news media representations between 1998 and 2008 suggest a positive change in the way people with disabilities are represented, with greater attention to the complexity of their identity and their multiple social roles. The participation of persons with disabilities in society continues to be limited by negative attitudes. Media reporting has a significant influence on public attitudes toward disability. In a content analysis of three Canadian newspapers, this study found several significant changes in the language and content of disability-related articles. Together, these changes provide some evidence of more favorable media representations of disability. Further research in rehabilitation is needed to understand how such changes may both reflect and facilitate ongoing efforts to enhance people with disabilties' participation in social life.

Media multitasking behavior: concurrent television and computer usage.

Science.gov (United States)

Brasel, S Adam; Gips, James

2011-09-01

Changes in the media landscape have made simultaneous usage of the computer and television increasingly commonplace, but little research has explored how individuals navigate this media multitasking environment. Prior work suggests that self-insight may be limited in media consumption and multitasking environments, reinforcing a rising need for direct observational research. A laboratory experiment recorded both younger and older individuals as they used a computer and television concurrently, multitasking across television and Internet content. Results show that individuals are attending primarily to the computer during media multitasking. Although gazes last longer on the computer when compared to the television, the overall distribution of gazes is strongly skewed toward very short gazes only a few seconds in duration. People switched between media at an extreme rate, averaging more than 4 switches per min and 120 switches over the 27.5-minute study exposure. Participants had little insight into their switching activity and recalled their switching behavior at an average of only 12 percent of their actual switching rate revealed in the objective data. Younger individuals switched more often than older individuals, but other individual differences such as stated multitasking preference and polychronicity had little effect on switching patterns or gaze duration. This overall pattern of results highlights the importance of exploring new media environments, such as the current drive toward media multitasking, and reinforces that self-monitoring, post hoc surveying, and lay theory may offer only limited insight into how individuals interact with media.

Who speaks for the climate now? Exploring portrayals of climate change through new/social media

Science.gov (United States)

Boykoff, M. T.

2011-12-01

Mass media stitch together formal science and policy with everyday activities in the public sphere. Many dynamic, contested and complex factors, along with non-nation state actors (or 'debate shapers'), contribute to how media outlets portray various facets of climate change. Against this backdrop, new and social media have become increasingly influential. The Pew Center Project for Excellence in Journalism has found that topics involving global warming have earned a much greater share of the news hole in new and social media (Internet weblogs, Twitter) than in traditional outlets (television, newspapers, radio), relative to other stories in those same media. This may be due in part to the flexibility and potentially infinite nature of the 'news hole' in new and social media, but may also mark the trends of diminishing traditional news room capabilities. Overall, new and social media have increasingly been harnessed in a variety of ways for communications about climate change around the world. However, with these shifts and developments come numerous questions. Among them: does increased visibility of climate change in new/social media translate to improved communication, or just more noise? Do these spaces provide opportunities for new forms of deliberative community regarding questions of climate mitigation and adaptation? Or has the content of this increased coverage shifted to polemics and arguments over measured traditional media analysis? In this more open space of content production, do new/social media provide more space for contrarian views to circulate? And through its interactivity, does increased consumption of news through new/social media further fragment a public discourse on climate mitigation and adaptation, through information silos where members of the public can stick to sources that help support their already held views? As new and social media representations of climate change demonstrate, the boundaries between who constitute 'authorized

2012-07-01

Deep geologic disposal of high activity and long-lived radioactive waste is gaining increasing support in many countries, where suitable low permeability geological formation in combination with engineered barriers are used to provide long term waste contaminant and minimise the impacts to the environment and risk to the biosphere. This modelling study examines the solute transport in fractured media under low flow velocities that are relevant to a deep geological environment. In particular, reactive solute transport through fractured media is studied using a 2-D model, that considers advection and diffusion, to explore the coupled effects of kinetic and equilibrium chemical processes. The effects of water velocity in the fracture, matrix porosity and diffusion on solute transport are investigated and discussed. Some illustrative modelled results are presented to demonstrate the use of the model to examine the effects of media degradation on solute transport, under the influences of hydrogeological (diffusion dominant) and microbially mediated chemical processes. The challenges facing the prediction of long term degradation such as cracks evolution, interaction and coalescence are highlighted. The potential of a novel microstructure informed modelling approach to account for these effects is discussed, particularly with respect to investigating multiple phenomena impact on material performance. The GRM code is used to examine the effects of media degradation for a geological waste disposal package, under the combined hydrogeological (diffusion dominant) and chemical effects in low groundwater flow conditions that are typical of deep geological disposal systems. An illustrative reactive transport modelling application demonstrates the use of the code to examine the interplay of kinetic controlled biogeochemical reactive processes with advective and diffusive transport, under the influence of media degradation. The initial model results are encouraging which show the

The growing popularity of social media as a channel for distributing and debating scientific information raises questions about the types of discourse that surround emerging technologies, such as nanotechnology, in online environments, as well as the different forms of information that audiences encounter when they use these online tools of information sharing. This study maps the landscape surrounding social media traffic about nanotechnology. Specifically, we use computational linguistic software to analyze a census of all English-language nanotechnology-related tweets expressing opinions posted on Twitter between September 1, 2010 and August 31, 2011. Results show that 55 % of tweets expressed certainty and 45 % expressed uncertainty. Twenty-seven percent of tweets expressed optimistic outlooks, 32 % expressed neutral outlooks and 41 % expressed pessimistic outlooks. Tweets were mapped by U.S. state, and our data show that tweets are more likely to originate from states with a federally funded National Nanotechnology Initiative center or network. The trend toward certainty in opinion coupled with the distinct geographic origins of much of the social media traffic on Twitter for nanotechnology-related opinion has significant implications for understanding how key online influencers are debating and positioning the issue of nanotechnology for lay and policy audiences.

Social media consist of powerful tools that impact not only communication but relationships among people, thus posing an inherent challenge to the traditional standards of who we are as dental educators and what we can expect of each other. This article examines how the world of social media has changed dental education. Its goal is to outline the complex issues that social media use presents for academic dental institutions and to examine these issues from personal, professional, and legal perspectives. After providing an update on social media, the article considers the advantages and risks associated with the use of social media at the interpersonal, professional, and institutional levels. Policies and legal issues of which academic dental institutions need to be aware from a compliance perspective are examined, along with considerations and resources needed to develop effective social media policies. The challenge facing dental educators is how to capitalize on the benefits that social media offer, while minimizing risks and complying with the various forms of legal constraint.

Full Text Available Within the framework of sociology of media the author explains the behavior of target audiences in the nowadays media environment, analyzes the changing nature of the relationship between the sender and the recipient of the message. The article considers the social mechanisms of the contemporary media institutions and changes in media consumption preferences of different social strata under the growing influence of communication technologies. The author believes that the digitalization determines the audience’s need for explanation instead of just information. The virtual reality as a new communication platform becomes a common practice, and the audience becomes its passive participant demanding new ways of real-time access to information. The print media audience is gradually moving from constant reading of one or two mass editions to the study of a large number of specialized media. There is the same trend of the declining share of main television channels in advertising budgets due to the increasing share of specialized network channels. At the same time, advertising budgets are transferred to the mobile platforms for there is a growing need in ‘big data’ in real time due to the fast development of mobile electronic devices. Tablets and smartphones are attributes of the emerging media ecology that are gradually replacing television for digital generations prefer to watch the same TV content ‘outside’ the traditional TV environment.

Climate Change Education: Student Media Production to Educate and Engage

Science.gov (United States)

Rooney-Varga, J. N.; Brisk, A. A.; Ledley, T. S.; Shuldman, M.

2011-12-01

Climate change education offers many challenges, including the complexity of the natural and human systems involved, a need for a multi-disciplinary perspective, and the psychological barriers to learning that result from a problem that frequently elicits a sense of being overwhelmed and powerless. The implications of climate change impacts and/or solutions can be especially overwhelming for today's students, who are likely to be confronted with many projected changes within their lifetimes. We are developing approaches to incorporate video production by students at both the high school and university levels in order to overcome many of the challenges unique to climate change education. Through media production, students are asked to convey complex topics using clear, simple language and metaphor, so their content knowledge must be deep enough to educate others. Video production is a team effort (director, camera person, editor, etc.) and inherently creates an opportunity for learning in a social context, which has been shown to lead to better learning outcomes in climate change education. Video production also promotes the basic tenets of engagement theory, in which a small group of students is in constant contact with the content and, ideally, creates a product that can be disseminated broadly. Lastly, putting students behind the camera can give them a voice and a sense of empowerment, fostering active participation in the learning process. While video is a medium that is readily disseminated to a broad audience, our focus is on the process (i.e., learning outcomes of students directly involved in media production), not the product. However, we have found that providing students with a means to add their voices to the broader public's discussion of climate change has a positive impact on student engagement with climate change science and on public awareness this problem beyond the classroom. While student-produced media pieces are not intended to provide in

Media advocacy: lessons from community experiences.

Science.gov (United States)

Jernigan, D H; Wright, P A

1996-01-01

Media advocacy is the strategic use of mass media and community organizing as a resource for advancing a social or public policy initiative. Across the United States, communities are using media advocacy to promote healthier public policies and environments. The U.S. Center for Substance Abuse Prevention commissioned numerous case studies of media advocacy on alcohol and tobacco issues in a diverse array of communities, including efforts in African-American and Latino communities or using computer-based electronic communication systems. The paper describes these efforts briefly, and summarizes lessons learned, including: media advocacy can lead to larger victories when used as a complement to community organizing in the context of a larger strategic vision for policy change; like policy advocacy, media advocacy is best done in the context of clear long-term goals; conscious framing, guiding the choice of spokespeople, visuals, and messages, can alter media coverage and public debate of health policies; advocates need to respect the media but also remember that they have power in relation to the media; and media advocacy is often controversial and not suited to every situation. The case studies show that media advocacy is a potent tool for public health workers, making an important contribution to campaigns to promote healthier public policies.

The Impact of Media on Consumers’ Environmental Behaviour

Directory of Open Access Journals (Sweden)

Gregor Jagodic

2016-12-01

Full Text Available People, companies and society are becoming more mindful about the environment, and thus the market demand environmentally-sustainable merchandises and services. Today consumers act more pro-environmentally, as in the past decades they have changed their behaviour. We all recognise that the development of different types of media, especially the Internet and social media, has generated a different approach from societies and traders towards the individual consumer. In this research, we have established that the Internet, social media and TV have at the moment the largest influence on consumers’ environmental behaviour, due to the fact that companies and marketers are targeting at the same time different target groups of consumers. In the case of the Internet or social media, the marketers are very aggressive, although many consumers have the sense that they are something special for the companies and, therefore, change their environmental behaviour following the marketers and companies’ desires.

Emotionally anesthetized: media violence induces neural changes during emotional face processing.

2015-10-01

Media violence exposure causes increased aggression and decreased prosocial behavior, suggesting that media violence desensitizes people to the emotional experience of others. Alterations in emotional face processing following exposure to media violence may result in desensitization to others' emotional states. This study used scalp electroencephalography methods to examine the link between exposure to violence and neural changes associated with emotional face processing. Twenty-five participants were shown a violent or nonviolent film clip and then completed a gender discrimination stop-signal task using emotional faces. Media violence did not affect the early visual P100 component; however, decreased amplitude was observed in the N170 and P200 event-related potentials following the violent film, indicating that exposure to film violence leads to suppression of holistic face processing and implicit emotional processing. Participants who had just seen a violent film showed increased frontal N200/P300 amplitude. These results suggest that media violence exposure may desensitize people to emotional stimuli and thereby require fewer cognitive resources to inhibit behavior. © The Author (2015).

Climate change, a quintessential environmental problem, is generally recognised as the most important development challenge in the 21st century (IPCC, 2014). In addition to acknowledging its many significant direct consequences, climate change is increasingly used to frame discussions on other important global challenges, such as health, energy and food security. This chapter provides understanding of the intricate and complex relationship between climate change, environment and development.

Raising the profile of Gender and Generation: The role of Climate Change Media Partnership

The paper details the initiatives taken by the Climate Change Media Partnership to strengthen journalists' understanding of the importance of gender and generation when reporting on climate change. Journalists from the world's wealthiest countries were well represented at the December 2007 UN Framework Convention on Climate change in Bali. In contrast only 9 percent of the journalists at the conference were from non-industrialised countries and there was zero media representation for nearly the entire UN list of 50 Least Developed Countries. To address this gap IIED Panos and Internews formed the Climate Change Media Partnership (CCMP). This initiative brought 37 journalists from developing countries to Bali and provided them with a 10 day programme of support. Since 2007, the CCMP has run three programmes each supporting nearly 40 journalists from developing nations to attend the UN climate change negotiations in Bali, Poznan and Copenhagen. Among the many refinements that the CCMP team has made to its programme over the years, is a greater focus on gender and generation. CCMP research has shown that although most male and female CCMP fellows were likely to acknowledge a need to include women's views in their reports, they lacked the resources, tools and knowledge to do so. In addition there is a disparate level of awareness amongst the CCMP journalists about how men and women of all ages are affected by climate change in different ways and about the need to report these differences. Through its work the CCMP identified several key areas that can improve the way that climate change, gender and generation are covered by the media.

Full Text Available The paper engages with what we refer to as “sensitive media,” a concept associated with developments in the overall media environment, our relationships with media devices, and the quality of the media themselves. Those developments point to the increasing emotionality of the media world and its infrastructures. Mapping the trajectories of technological development and impact that the newer media exert on human condition, our analysis touches upon various forms of emergent affect, emotion, and feeling in order to trace the histories and motivations of the sensitization of “the media things” as well as the redefinition of our affective and emotional experiences through technologies that themselves “feel.”

In a changing healthcare environment, patient loyalty has never been more important. However, creating patient loyalty can mean more than providing quality health services within the four walls of the medical office. With patients turning to online sources and social media in search of advice and a better patient experience, we must now ensure that patients have meaningful engagements with us across the continuum of care, from the phone, to the office, to social media tools like Facebook and YouTube as we look to build loyalty and grow our referral volumes.

2017-01-01

The translation of science from research to real-world change is a central goal of public health. Communication has an essential role to play in provoking a response to climate change. It must first raise awareness, make people feel involved and ultimately motivate them to take action. The goal of this research is to understand how the information related to this issue is being addressed and disseminated to different audiences-public citizens, politicians and key climate change stakeholders. Initial results show that the scientific voice struggles to globally highlight this issue to a general audience and that messages that address the topic do not meet the challenges, going from a dramatic framing to a basic adaptation framing. Communication experts can help inform scientists and policy makers on how to best share information about climate change in an engaging and motivating way. This study gives an insight about the key role of the media and communications in addressing themes relating to climate change and transmitting information to the public in order to take action.

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.

Transformers: changing the face of nursing and midwifery in the media.

McAllister, Margaret; Downer, Terri; Hanson, Julie; Oprescu, Florin

2014-03-01

This paper reports an educational strategy designed to sensitise and empower students about the impact of media representations of nursing and midwifery on their public image. Numerous studies continue to reveal that stories about nursing and midwifery presented in the mainstream media are often superficial, stereotypical and demeaning. Inaccurate portrayals of nursing damage our professional reputation with the public and potential consumers. It also sends the wrong message to future nursing students. Images are a powerful conductor of misinformation, suggesting to others that nurses are not important agents for social change. In 2012, a small team of academics designed a photography competition and judging process for undergraduate and postgraduate students of nursing and midwifery enrolled at a regional Australian university. The winning entries were photographs of high quality and conveyed rich meaning. They provide an interesting and positive counterpoint to derogatory images often propagated by mainstream media. There is benefit in extending this project so that it: appeals to more students, builds leadership skills, leads to wider social change and benefits society. The intention is to develop the process of student engagement as an educational intervention, and explore experiences and outcomes with stakeholders. Copyright © 2013 Elsevier Ltd.

When climate science became climate politics: British media representations of climate change in 1988.

Science.gov (United States)

Jaspal, Rusi; Nerlich, Brigitte

2014-02-01

Climate change has become a pressing environmental concern for scientists, social commentators and politicians. Previous social science research has explored media representations of climate change in various temporal and geographical contexts. Through the lens of Social Representations Theory, this article provides a detailed qualitative thematic analysis of media representations of climate change in the 1988 British broadsheet press, given that this year constitutes an important juncture in this transition of climate change from the domain of science to that of the socio-political sphere. The following themes are outlined: (i) "Climate change: a multi-faceted threat"; (ii) "Collectivisation of threat"; (iii) "Climate change and the attribution of blame"; and (iv) "Speculative solutions to a complex socio-environmental problem." The article provides detailed empirical insights into the "starting-point" for present-day disputes concerning climate change and lays the theoretical foundations for tracking the continuities and discontinuities characterising social representations of climate change in the future.

Weal, Mark; Morrison, Leanne; Yardley, Lucy

2018-01-01

Background Incorporating social media features into digital behavior change interventions (DBCIs) has the potential to contribute positively to their success. However, the lack of clear design principles to describe and guide the use of these features in behavioral interventions limits cross-study comparisons of their uses and effects. Objective The aim of this study was to provide a systematic review of DBCIs targeting modifiable behavioral risk factors that have included social media features as part of their intervention infrastructure. A taxonomy of social media features is presented to inform the development, description, and evaluation of behavioral interventions. Methods Search terms were used in 8 databases to identify DBCIs that incorporated social media features and targeted tobacco smoking, diet and nutrition, physical activities, or alcohol consumption. The screening and review process was performed by 2 independent researchers. Results A total of 5264 articles were screened, and 143 articles describing a total of 134 studies were retained for full review. The majority of studies (70%) reported positive outcomes, followed by 28% finding no effects with regard to their respective objectives and hypothesis, and 2% of the studies found that their interventions had negative outcomes. Few studies reported on the association between the inclusion of social media features and intervention effect. A taxonomy of social media features used in behavioral interventions has been presented with 36 social media features organized under 7 high-level categories. The taxonomy has been used to guide the analysis of this review. Conclusions Although social media features are commonly included in DBCIs, there is an acute lack of information with respect to their effect on outcomes and a lack of clear guidance to inform the selection process based on the features’ suitability for the different behaviors. The proposed taxonomy along with the set of recommendations included

The family food environment is an important influence in the development of children's dietary habits. Research suggests that influences of current dietary behaviour and behaviour change may differ. The aims of this paper were to: (1) investigate the association between the food environment at baseline and change in children's saturated fat intake; and (2) to explore whether a change in the food environment was associated with a change in children's saturated fat intake. Secondary analysis of a 12 week cluster randomised controlled trial in 133 4-13 year old children. Families were randomly allocated to parental education regarding changing to reduced-fat dairy foods or a comparison non-dietary behaviour. The interventions were family focused. Parents received education from a dietitian in 3x30 minute sessions to facilitate behaviour change. Parents completed a comprehensive questionnaire capturing three domains of the food environment--Parent knowledge and attitudes; shaping practices; and behaviours and role modelling. Children's dietary intake was assessed via multiple 24-hour recalls at baseline and week 12. Changes in the family food environment and primary outcome (saturated fat) were calculated. Hierarchical linear regression models were performed to explore the association between baseline and change in food environment constructs and change in saturated fat intake. Standardised Beta are presented (pchange in saturated fat. An increase in nutrition knowledge (β=-0.2), perceived responsibility (β=-0.3) and restriction (β=-0.3) from baseline to week 12 were associated with greater reduction in saturated fat intake. The present study was one of the first to quantify changes in the family food environment, and identify a number of factors which were associated with a positive dietary change. Because interventions focus on behaviour change, the findings may provide specific targets for intervention strategies in the future. Australia New Zealand Clinical

Full Text Available Digital media raise methodological issues of some relevance. The following article tries to be a contribution to the qualitative analysis of Social Networks through the use of media ethnography. We deal with issues such as time and space and with how these dimension get transformed in digital environments; the very definition of environment and social network; an effective communication; the constant flow between online and off-line activities; the role of the “digital” researcher, his/her influence on the subjects’ actions, his/her actual competence about the media and the balance of the management of situations that cross online and off-line environments, ethics and the protection of privacy. The figure of the ethnographic researcher changes, while ethnography represents – perhaps – one of the most effective methods for a research that maintains a phenomenological basis, helping to understand the meaning and value that certain tools, used for specific purposes, can take on for the youngest users.

People as sensors: mass media and local temperature influence climate change discussion on Twitter

Science.gov (United States)

Kirilenko, A.; Molodtsova, T.; Stepchenkova, S.

2014-12-01

We examined whether people living under significant temperature anomalies connect their sensory experiences to climate change and the role that media plays in this process. We used Twitter messages containing words "climate change" and "global warming" as the indicator of attention that public pays to the issue. Specifically, the goals were: (1) to investigate whether people immediately notice significant local weather anomalies and connect them to climate change and (2) to examine the role of mass media in this process. Over 2 million tweets were collected for a two-year period (2012 - 2013) and were assigned to 157 urban areas in the continental USA (Figure 1). Geographical locations of the tweets were identified with a geolocation resolving algorithm based the profile of the users. Daily number of tweets (tweeting rate) was computed for 157 conterminous USA urban areas and adjusted for data acquisition errors. The USHCN daily minimum and maximum temperatures were obtained for the station locations closest to the centers of the urban areas and the 1981-2010 30-year temperature mean and standard deviation were used as the climate normals. For the analysis, we computed the following indices for each day of 2012 - 2013 period: standardized temperature anomaly, absolute standardized temperature anomaly, and extreme cold and hot temperature anomalies for each urban zone. The extreme cold and hot temperature anomalies were then transformed into country-level values that represent the number of people living in extreme temperature conditions. The rate of tweeting on climate change was regressed on the time variables, number of climate change publications in the mass media, and temperature. In the majority of regression models, the mass media and temperature variables were significant at the pmedia acts as a mediator in the relationship between local weather and climate change discourse intensity.

Cultures obtained from pre-operative middle-ear swabs from patients with chronic otitis media have traditionally been used to guide antibiotic selection. This study investigated changes in the bacterial strains of the middle ear during chronic otitis media surgery. Pre-operative bacterial cultures of otorrhoea, and peri-operative cultures of the granulation tissue in either the middle ear or mastoid cavity, were obtained. Post-operative cultures were selectively obtained when otorrhoea developed after surgery. Bacterial growth was observed in 45.5 per cent of pre-operative cultures, 13.5 per cent of peri-operative cultures and 4.5 per cent of post-operative cultures. Methicillin-resistant Staphylococcus aureus was identified as the most common bacteria in all pre-operative (32.4 per cent), peri-operative (52.4 per cent) and post-operative (71.4 per cent) tests, and the percentage of Methicillin-resistant S aureus increased from the pre- to the post-operative period. The bacterial culture results for post-operative otorrhoea showed low agreement with those for pre-operative or peri-operative culture, and strain re-identification was required.

Austin, Erica Weintraub; Pinkleton, Bruce E; Radanielina-Hita, Marie Louise; Ran, Weina

2015-01-01

A convenience survey completed online by 137 4-H parents in Washington state explored their orientation toward critical thinking regarding media sources and content and its implications for family dietary behaviors. Parents' critical thinking toward media sources predicted their information efficacy about content. Critical thinking toward media content predicted information efficacy about sources, expectancies for parental mediation, and expectancies for family receptiveness to lower-fat dietary changes. Expectancies for receptiveness to dietary changes and expectancies for parental mediation predicted efficacy for implementing healthy dietary practices; this strongly predicted healthy dietary practices. Media-related critical thinking, therefore, indirectly but consistently affected self-reported family dietary behaviors through its effects on efficacy for managing media and expectancies for the family's receptiveness to healthy dietary changes. The results suggest parents' media literacy skills affect their family's dietary behavior. Health campaigns that help parents interpret and manage the media environment may benefit all family members.

Re-Examination of Mixed Media Communication: The Impact of Voice, Data Link, and Mixed Air Traffic Control Environments on the Flight Deck

Dunbar, Melisa; McGann, Alison; Mackintosh, Margaret-Anne; Lozito, Sandra; Ashford, Rose (Technical Monitor)

2001-01-01

A simulation in the B747-400 was conducted at NASA Ames Research Center that compared how crews handled voice and data link air traffic control (ATC) messages in a single medium versus a mixed voice and data link ATC environment The interval between ATC messages was also varied to examine the influence of time pressure in voice, data link, and mixed ATC environments. For messages sent via voice, transaction times were lengthened in the mixed media environment for closely spaced messages. The type of environment did not affect data link times. However, messages times were lengthened in both single and mixed-modality environments under time pressure. Closely spaced messages also increased the number of requests for clarification for voice messages in the mixed environment and review menu use for data link messages. Results indicated that when time pressure is introduced, the mix of voice and data link does not necessarily capitalize on the advantages of both media. These findings emphasize the need to develop procedures for managing communication in mixed voice and data link environments.

Our study aimed to evaluate pathologic changes in the cochlear (inner and outer hair cells and stria vascularis) and vestibular (vestibular hair cells, dark, and transitional cells) sensorial elements in temporal bones from donors who had otitis media. We studied 40 temporal bones from such donors, which were categorized in serous otitis media (SOM), serous-purulent otitis media (SPOM), mucoid/mucoid-purulent otitis media (MOM/MPOM), and chronic otitis media (COM); control group comprised 10 nondiseased temporal bones. We found significant loss of inner and outer cochlear hair cells in the basal turn of the SPOM, MOM/MPOM and COM groups; significant loss of vestibular hair cells was observed in the MOM/MPOM and COM groups. All otitis media groups had smaller mean area of the stria vascularis in the basal turn of the cochlea when compared to controls. In conclusion, our study demonstrated more severe pathologic changes in the later stages of the continuum of otitis media (MOM/MPOM and COM). Those changes seem to progress from the basal turn of the cochlea (stria vascularis, then inner and outer hair cells) to the middle turn of the cochlea and to the saccule and utricle in the MOM/MPOM and COM stages.

Media ion composition controls regulatory and virulence response of Salmonella in spaceflight.

Directory of Open Access Journals (Sweden)

James W Wilson

Full Text Available The spaceflight environment is relevant to conditions encountered by pathogens during the course of infection and induces novel changes in microbial pathogenesis not observed using conventional methods. It is unclear how microbial cells sense spaceflight-associated changes to their growth environment and orchestrate corresponding changes in molecular and physiological phenotypes relevant to the infection process. Here we report that spaceflight-induced increases in Salmonella virulence are regulated by media ion composition, and that phosphate ion is sufficient to alter related pathogenesis responses in a spaceflight analogue model. Using whole genome microarray and proteomic analyses from two independent Space Shuttle missions, we identified evolutionarily conserved molecular pathways in Salmonella that respond to spaceflight under all media compositions tested. Identification of conserved regulatory paradigms opens new avenues to control microbial responses during the infection process and holds promise to provide an improved understanding of human health and disease on Earth.

Incorporating social media features into digital behavior change interventions (DBCIs) has the potential to contribute positively to their success. However, the lack of clear design principles to describe and guide the use of these features in behavioral interventions limits cross-study comparisons of their uses and effects. The aim of this study was to provide a systematic review of DBCIs targeting modifiable behavioral risk factors that have included social media features as part of their intervention infrastructure. A taxonomy of social media features is presented to inform the development, description, and evaluation of behavioral interventions. Search terms were used in 8 databases to identify DBCIs that incorporated social media features and targeted tobacco smoking, diet and nutrition, physical activities, or alcohol consumption. The screening and review process was performed by 2 independent researchers. A total of 5264 articles were screened, and 143 articles describing a total of 134 studies were retained for full review. The majority of studies (70%) reported positive outcomes, followed by 28% finding no effects with regard to their respective objectives and hypothesis, and 2% of the studies found that their interventions had negative outcomes. Few studies reported on the association between the inclusion of social media features and intervention effect. A taxonomy of social media features used in behavioral interventions has been presented with 36 social media features organized under 7 high-level categories. The taxonomy has been used to guide the analysis of this review. Although social media features are commonly included in DBCIs, there is an acute lack of information with respect to their effect on outcomes and a lack of clear guidance to inform the selection process based on the features' suitability for the different behaviors. The proposed taxonomy along with the set of recommendations included in this review will support future research aimed

2018-03-01

Full Text Available As the virtual environment is constantly changing, not only users’ informational and knowledge needs but also the means and channels of communication with customers applied by organizations change. There is a noticeable trend to move more and more advertising campaigns to social media networks because of the opportunities they provide to organizations and users, which results in the ever-increasing popularity of social media networks and a number of their users. Such a transition is explained by one of the main objectives organizations have: to inform their customers in an appropriate way and receive feedback on social media networks, which is difficult when traditional advertising channels and means are applied. Since advertising campaigns on social media networks are evolving rapidly, their assessment factors and methods, which receive controversial opinions in both scientific literature and practice, change too. Researchers assess and interpret the factors that influence the effectiveness of advertising campaigns on social media networks differently. Thus, a problem arises: how should we evaluate which approach is more capable of accurately and fully reflecting and conveying reality? In this research, this problem is studied by connecting approaches of different researchers. These approaches are linked to the effectiveness assessment of advertising campaigns on social media network aspects. To achieve the objective of this study, such research methods as analysis of scientific literature, multiple criteria and expert assessment (a structured survey and an interview were applied. During the study, out of 39 primary assessment factors, eight primary factors that influence the effectiveness of advertising campaigns on social media networks were identified: sales, content reach, traffic to website, impressions, frequency, relevance score, leads and audience growth.

Full Text Available Handheld digital devices are rapidly increasing their sensory capabilities for registering multiple types of input, such as movement, orientation, position and touch, as well as light and sound. Mobile Augmented Rreality is one of the emerging forms of representation and expression that exploits these sensory media. In the following text we will present and discuss a type of indirect augmented reality, which we call situated simulations. In a situated simulation there is approximate identity between the 3D environment displayed on the screen and the user's real perspective on a given location. This makes it possible to create simulations of relevant objects and environments related to a specific place, for example, interpretations of its past. We present a situated simulation

Full Text Available Abstract Background The family food environment is an important influence in the development of children’s dietary habits. Research suggests that influences of current dietary behaviour and behaviour change may differ. The aims of this paper were to: (1 investigate the association between the food environment at baseline and change in children’s saturated fat intake; and (2 to explore whether a change in the food environment was associated with a change in children’s saturated fat intake. Method Secondary analysis of a 12 week cluster randomised controlled trial in 133 4-13 year old children. Families were randomly allocated to parental education regarding changing to reduced-fat dairy foods or a comparison non-dietary behaviour. The interventions were family focused. Parents received education from a dietitian in 3x30minute sessions to facilitate behaviour change. Parents completed a comprehensive questionnaire capturing three domains of the food environment – Parent knowledge and attitudes; shaping practices; and behaviours and role modelling. Children’s dietary intake was assessed via multiple 24-hour recalls at baseline and week 12. Changes in the family food environment and primary outcome (saturated fat were calculated. Hierarchical linear regression models were performed to explore the association between baseline and change in food environment constructs and change in saturated fat intake. Standardised Beta are presented (p Results After adjustments for child and family demographics, higher levels of perceived food availability (β=-0.2 at baseline was associated with greater reduction in saturated fat intake, where as higher perceived responsibility (β=0.2, restriction (β=0.3 and pressure to eat (β=0.3 were associated with lesser change in saturated fat. An increase in nutrition knowledge (β=-0.2, perceived responsibility (β=-0.3 and restriction (β=-0.3 from baseline to week 12 were associated with greater reduction in

Social media for lifelong learning.

Kind, Terry; Evans, Yolanda

2015-04-01

Learning is ongoing, and can be considered a social activity. In this paper we aim to provide a review of the use of social media for lifelong learning. We start by defining lifelong learning, drawing upon principles of continuous professional development and adult learning theory. We searched Embase and MEDLINE from 2004-2014 for search terms relevant to social media and learning. We describe examples of lifelong learners using social media in medical education and healthcare that have been reported in the peer-reviewed literature. Medical or other health professions students may have qualities consistent with being a lifelong learner, yet once individuals move beyond structured learning environments they will need to recognize their own gaps in knowledge and skills over time and be motivated to fill them, thereby incorporating lifelong learning principles into their day-to-day practice. Engagement with social media can parallel engagement in the learning process over time, to the extent that online social networking fosters feedback and collaboration. The use of social media and online networking platforms are a key way to continuously learn in today's information sharing society. Additional research is needed, particularly rigorous studies that extend beyond learner satisfaction to knowledge, behaviour change, and outcomes.

Information and Communication Technologies in Creating Political Media Reality in Russia

Directory of Open Access Journals (Sweden)

Marianna Yu. Pavlyutenkova

2017-01-01

Full Text Available The article explores intended use of infocomms in creation of political media reality, acting as a virtual environment, effectively replacing reality. A noteworthy detail is that mainstreaming of information and communication technologies into political sphere substantially increases the authoritative potential for the media discourse. Those forces that assert their own media versions of events and media images for their participants have been winning in the competitive struggle amidst media discourses today. Furthermore, all available communication channels (television, media, Internet resources, mobile telecommunications are used to set up a political pseudo-environment for their information consumers, replacing political reality. The article shows what way new media resources, initially aimed at manipulating the mass consciousness in the pre-election race are being incorporated today. In particular, impressive manipulative media effects are demonstrated when a fake discourse is included in the media space. In addition, computer attacks, hacking, and the prime of independent cyber organizations fighting against the “world evil” are in effect as an instrument in the political struggle, in obtaining compromising material and interstate opposition. The work records the inclusion of graphic elements, emoji, clips in the media discourse. In general, symbols, encroaching into the politics space, become a part of the political mainstream, change the style of political demonstrations, discussions, chats that unite adherents to influence the actions of the authorities. It follows that the political media reality design, supported by the latest information and communication technologies tools, directly affects the perception of what is happening on a global scale, quickly formatting the mass consciousness.

The aim of this study was to determine changes in advertising expenditures across eight media channels for the four main alcohol beverage types and alcohol retailers in Australia. Yearly advertising expenditures between January 1997 and December 2011 obtained from a leading media-monitoring company. Media channels assessed were: free-to-air television, newspapers, magazines, radio, outdoors (billboards), cinema, direct mail (from 2005) and online (from 2008). Data were categorised into alcohol retailers (e.g. supermarkets, off-licences) or four alcoholic beverage types (beer, wine, spirits, premixed spirits/cider). Regression analyses examined associations between year and expenditure. Total alcohol advertising expenditure peaked in 2007, then declined to 2011 (P = 0.02). Television advertising expenditure declined between 2000 and 2011 (P advertising expenditure increased between 1997 and 2007. Alcohol retailers' advertising expenditure increased over time (P advertising expenditure declined over time (beer: P advertising expenditure increased (beer: P advertised beer (P advertising alcohol. As our study excluded non-traditional advertising media (e.g. sponsorships, in-store) we cannot determine whether declines in television advertising have been offset by increases in advertising in newer media channels. However, our findings that media channels used for alcohol advertising have changed over time highlights the need for adequate controls on alcohol advertising in all media channels.

McCabe, Marita P; McGreevy, Shauna J

2011-01-01

There has been limited previous research that has examined the role of sociocultural influences on body change strategies among adult men. The current study investigated the role of specific types of messages (encouragement, teasing and modelling) from peers and the media on the strategies to change weight among adult men. Differences were evaluated between 526 men aged from 18 to 60 years from three groups (normal weight, overweight and obese) on body image, body change strategies and messages about their body received from peers and the media. Men were primarily drawn from United States, Australia and Europe. Results showed that messages received by men regarding losing weight or increasing muscle size differed according to weight. Body image and media messages were the strongest predictors of losing weight, whereas body image importance and messages from peers were the strongest predictors of increasing muscles. These findings highlight the importance of sociocultural influences on body change strategies among adult males. Copyright © 2010 John Wiley & Sons, Ltd and Eating Disorders Association.

Using social media to facilitate knowledge transfer in complex engineering environments: a primer for educators

Science.gov (United States)

Murphy, Glen; Salomone, Sonia

2013-03-01

While highly cohesive groups are potentially advantageous they are also often correlated with the emergence of knowledge and information silos based around those same functional or occupational clusters. Consequently, an essential challenge for engineering organisations wishing to overcome informational silos is to implement mechanisms that facilitate, encourage and sustain interactions between otherwise disconnected groups. This paper acts as a primer for those seeking to gain an understanding of the design, functionality and utility of a suite of software tools generically termed social media technologies in the context of optimising the management of tacit engineering knowledge. Underpinned by knowledge management theory and using detailed case examples, this paper explores how social media technologies achieve such goals, allowing for the transfer of knowledge by tapping into the tacit and explicit knowledge of disparate groups in complex engineering environments.

Full Text Available The development of the internet and the expansion of digitalization changed the way society works, especially mass-media. The question is if the internet was an advantage or a disadvantage for mass-media? Apparently, on one hand digitalization determined the reduction of production and distribution costs but also content diversification. At the same time, social media and rapid documentation brought an accession in the quality of journalistic product as well as the entering on the market of multiple actors, in consequence, more ideas more carefully selected. On the other hand, it is possible that the internet may have increased the volume of information, detrimental to its credibility. In other words, the quality of the journalistic act and its results have been altered or at least crippled. Methodologically, starting from the observation of the actual situation in mass-media industry and economy, we propose to make a content analysis. We will talk about aspects concerning the challenges and the opportunities from media industry in the digital context, analyzing the opinions of other researchers about the topic. We are trying to present the concepts that we sustain in the light of some reference works and to give examples from the reality of Romanian and international mass-media economy. The mass-media sector in the digital world is confronting with opportunities and challenges. The change isn’t simple and without risks but is expensive and may be the only way of survival for each of the societies in this sector. In order to build successful businesses in media industry just like in any other sectors, sustainable growth has to be the main characteristic. Sustainable development, predictability and upward economic growth are possible only taking into account the context in which the organization operates.

Full Text Available Technology no doubt is the engine that drives the modern world, both for destruction and good; and one of the wonders of modern technology is the computer and the allied internet. Modern communication network now relies on the internet using the computer and mobile telephones. In fact, there is no place to hide with the internet and the handy smart phones with which calls are made and pictures and videos recorded and transmitted across boundaries and continents. The advancements in the computer and internet systems in the last decade of the 20th century produced radical changes in both internet connectivity and features available to users through which people are linked across the globe. The three most basic of these internet features that have radically shaped modern communication are, Facebook, Twitters, and the U-Tube, among others. The three are the most popular and core elements of the social media compartment of our modern internet system. Computer technology has broken the boundaries of closed societies and systems, making actions and activities in such systems open and available to the wider world. Through the internet and its core elements, repressive regimes have been exposed and activities going on in liberal societies are shared. Interestingly, Africa became the starting point for the agitation for political change, which was bolstered by the social media. The so-called “Arab Spring”, which first started in Africa through expositions of social media, saw the dismantling of three despotic and ruthless regimes in Arab North Africa, thus giving vent to agitations for an end to dictatorship and illiberality in other Arab states. The paper will examine the role of the social media in political transformation and change of dictatorial regimes in Africa and the consequences such would have on the overall political template of Africa.

Full Text Available More than one hundred years ago, once the radio appeared, mass media started to be more pronounced. Mass-media market diversified its offer, and the quality and creativity of economical agents determined a reassert on the competition and performance scale. For our research in mass media field, we distinguish two vital aspects of economic quality and performance: audience and financial results. In this section we will try to follow the evolution of the main players from the Romanian audio-visual market on the radio segment, taking into account these two variables: audience and financial results. Quality and performance in mass-media are two elements desired on one side by massmedia producers: the owners and employees from this field, and on the other side, by mass-media customers: audience and publicity buyers. We analyse the aspects of quality and performance in Romanian media industry in o period of rapid change. The changes are on multiple levels, and the most accentuated regards the consumer’s behaviour, market environment, technological changes and legal regulations. The changes in the consumer behaviour are determined by their perceptiveness towards the digital world. Quality and performance in mass-media are two desired elements, on one side by the mass-media producers: owners and employees in the field, and on the other side by massmedia customers: audience and publicity buyers.

CHANGE MANAGEMENT STRATEGIES RELATED TO THE GLOBAL ENVIRONMENT COMPLEXITY

Directory of Open Access Journals (Sweden)

Elena DOVAL

2016-12-01

Full Text Available The changes in organizations appear as a reaction to the organizational environment changes. In order to manage these changes successfully, the managers need to anticipate and design alternative strategies by preparing different options.  Nevertheless, the complexity of the global environment forces the managers to adopt strategies for their organizations that are facilitating the creation of new strategic competences and competitive advantages to face the environmental rapid changes. In this context, this paper is aiming to illustrate the main directions the change management may consider to change the organization strategies in order to harmonize them to the external environment, such as: integration versus externalization, flexible specialization and flexible organization, standardization versus adaptation, market segmentation, relationship building and maintaining and communication integration.  However, the new strategies are based on a changed attitude of the managers towards the competitive advantage that is dynamic and focused on creation rather then to operations.

How Social Media is Changing the Practice of Regional Anesthesiology.

Schwenk, Eric S; Chu, Larry F; Gupta, Rajnish K; Mariano, Edward R

2017-06-01

This review summarizes the current applications of social media in regional anesthesiology, describes ways that specific platforms may promote growth, and briefly discusses limitations and future directions. Although Facebook users outnumber Twitter users, the latter has been better studied in regional anesthesiology and may have the advantages of speed and expansion of reach. Highly tweeted publications are more likely to be cited in the medical literature, and twitter-enhanced journal clubs facilitate communication regarding important articles with international colleagues. In both the United States and internationally, Twitter has been shown to enhance the anesthesiology conference experience, changing communication among attendees and non-attendees. YouTube and podcasts are quickly finding a niche in regional anesthesiology for just-in-time training and continuing professional development. Social media use is rapidly growing in regional anesthesiology, and benefits include global interaction and knowledge translation within the specialty and with the general public.

Feed the dogs: The case of humanitarian communication in social media

2016-06-01

Full Text Available In this paper we address the interplay between networked media and humanitarian communication through the lens of meditization theory in order to forward a more balanced understanding of networked humanitarianism. We analyze a case of humanitarian communication that travelled Facebook in unpredictable ways and demonstrate the breakdown between sender and receiver positions. The case shows how communicative practices are challenged and how humanitarian organizations are destabilized in a new and unpredictable communication environment. We argue that in order to deepen the critical perspective on networked humanitarian communication, it is important to better understand how the institutional logic of humanitarianism changes when mediatized through networked media. Further, we suggest that a broader consideration of media amalgamation enables a critical discussion of networked media influence humanitarianism.

Social Communication between Traditional and the New Mass-Media

2014-05-01

Full Text Available The means of communication, from the most simple and natural ones – such as gestures and voice, to the most complex and developed ones – such as the new electronic media, have constantly brought changes to the society, their own transformation being due to the social environment that generated them. Nowadays, the new media – being in a rapid development unprecedented in the past – is giving new insights of communication and learning to the younger generations which, unlike those formed by elder people, manage to quickly assimilate the changes that occur. The purpose of this article is to provide a framework for public institutions for a better interaction with citizens. It shows the literature that focuses on social media statistics. At the end of our study, it is necessary to refer again to the needs of the organizations in which social communication has its origins, to exit the logic of politics and the media and to completely redefine the relationship between them and the social communication itself. We have treated the terms of the relationship between media and social communication, but it is the case to reiterate the importance of this point. In this context, we have identified the social nature still in embryo of a new relationship between media and educational sector; the more fragile the more difficult it is to overcome the stereotype of the “recreational” media.

Pharmaceutical pollution in the aquatic environment is an issue of concern that has attracted attention by the news media. Understanding the factors that contribute to media framing of pharmaceutical pollution may lead to a better understanding of the management and governance of this issue, including why these pollutants are generally unregulated at this time. This study conducted a content analysis of 405 newspaper articles (81 had substantive information on the topic) from 2007 to 2014, using the search terms "water" and "pharmaceuticals" in the Chicago Tribune, Denver Post, Los Angeles Times, New York Daily News, New York Times, USA Today, Wall Street Journal, and Washington Post. We sought to analyze the factors that contributed to the news media presentation of pharmaceutical pollution in the United States, including the presentation of the risks/safety and solutions by various actors. We found that the primary issues in the news media were uncertainty regarding public health and harm to the environment. The primary solutions recommended within the news media were implementing additional water treatment technologies, taking unused pharmaceuticals to predetermined sites for disposal (take-back programs), and trash disposal of unused pharmaceuticals. Water utilities and scientists presented improved water treatment technology, government actors presented take-back programs, and pharmaceutical representatives, while sparsely involved in the news media, presented trash disposal as their primary solutions. To advance the understanding of the management of pharmaceutical pollution, this article offers further insight into the debate and potential solutions within the news media presentation of this complex scientific topic.

This study tests how the use of online media for different purposes (social interaction, creative expression, online news use, social media news use) is related to three types of political...... participation. It examines whether mobilizing effects are partly indirect due to different understandings of citizenship (dutiful, optional, individual, collective) that may be fostered by digital media use. The study is based on a survey of a sample of the Danish population (n = 1322), including data from two...... online survey waves and a smartphone-based media diary that documents respondents’ social media use. Results indicate support for a new pathway to participation, but the relationship depends on whether citizens are socialized in a digital media environment....

Social Media as a Catalyst for Policy Action and Social Change for Health and Well-Being: Viewpoint

Science.gov (United States)

2018-01-01

This viewpoint paper argues that policy interventions can benefit from the continued use of social media analytics, which can serve as an important complement to traditional social science data collection and analysis. Efforts to improve well-being should provide an opportunity to explore these areas more deeply, and encourage the efforts of those conducting national and local data collection on health to incorporate more of these emerging data sources. Social media remains a relatively untapped source of information to catalyze policy action and social change. However, the diversity of social media platforms and available analysis techniques provides multiple ways to offer insight for policy making and decision making. For instance, social media content can provide timely information about the impact of policy interventions. Social media location information can inform where to deploy resources or disseminate public messaging. Network analysis of social media connections can reveal underserved populations who may be disconnected from public services. Machine learning can help recognize important patterns for disease surveillance or to model population sentiment. To fully realize these potential policy uses, limitations to social media data will need to be overcome, including data reliability and validity, and potential privacy risks. Traditional data collection may not fully capture the upstream factors and systemic relationships that influence health and well-being. Policy actions and social change efforts, such as the Robert Wood Johnson Foundation’s effort to advance a culture of health, which are intended to drive change in a network of upstream health drivers, will need to incorporate a broad range of behavioral information, such as health attitudes or physical activity levels. Applying innovative techniques to emerging data has the potential to extract insight from unstructured data or fuse disparate sources of data, such as linking health attitudes that

Staying Relevant in a Crowded Media Environment: Telling Stories about Ever Changing Forests

The USDA Forest Service's Forest Inventory and Analysis program faces a serious challenge: how do we communicate information about the status and trends of the nation's forest resource to a public whose appetite for reading is declining rapidly? Our data, reports, and analyses are highly regarded; states demand our data be loaded into FIADB ever more quickly, and the time from the last plot to a published report is shrinking. At the same time, the average person spends only 25 minutes per day with print media. The Forest Service seeks to address the challenge by releasing reports as PDFs and e-books, but there are exciting opportunities to increase reader engagement with our content. Here, we discuss our evolving strategy for integrating traditional data delivery tools with cutting edge technology like ArcGIS Online and free JavaScript libraries to create visually compelling, interactive and information-rich experiences for an increasingly diverse set of target audiences. You can try these tools yourself by checking out our Engagement Portfolio.

Evidence Accumulation and Change Rate Inference in Dynamic Environments.

In a constantly changing world, animals must account for environmental volatility when making decisions. To appropriately discount older, irrelevant information, they need to learn the rate at which the environment changes. We develop an ideal observer model capable of inferring the present state of the environment along with its rate of change. Key to this computation is an update of the posterior probability of all possible change point counts. This computation can be challenging, as the number of possibilities grows rapidly with time. However, we show how the computations can be simplified in the continuum limit by a moment closure approximation. The resulting low-dimensional system can be used to infer the environmental state and change rate with accuracy comparable to the ideal observer. The approximate computations can be performed by a neural network model via a rate-correlation-based plasticity rule. We thus show how optimal observers accumulate evidence in changing environments and map this computation to reduced models that perform inference using plausible neural mechanisms.

Public Agility and Change in a Network Environment

2011-03-01

Full Text Available Preparing for change is increasingly core business for governmental organizations. The networked society and the increasing connectedness of governmental organizations have as much impact on the complexity of the change process as the complexities of the corpus of law. Change is not only driven by changes in the law; changes in the organization’s environment often create a need to redesign business processes, reallocate roles and responsibilities, and reorder tasks. Moreover, preparations for change are not limited to the internal processes and systems of these organizations. Propagation of changes to network partners and redesign of network arrangements can be an enormous challenge. In the AGILE project, we develop a design method, distributed service architecture, and supporting tools that enable organizations - administrative and otherwise - to orchestrate their law-based services in a networked environment. This paper explains the Agile approach and describes some of its key principles.

Kagurusi, Patrick T

2013-09-01

The media has been employed to increase uptake of Family Planning through behaviour change communication (BCC). Understanding the barriers encountered in effectively undertaking this function would increase the strategy's effectiveness. Sixty journalists from East Africa participated in trainings to enhance their BCC skills for Family Planning in which a qualitative study was nested to identify barriers to effective Family Planning BCC in the region's media. The barriers were observed to be insufficient BCC skills, journalists' conflict of interest, interests of media houses, inaccessible sources of family planning information, editorial ideologies and absence of commercially beneficial demand. Coupled with the historical ideologies of the media in the region, the observed barriers have precipitated ineffective family planning BCC in the regions media. Effective BCC for family planning in the regions media requires capacity building among practitioners and alignment of the concept to the media's and consumers' aspirations.

Radiation-induced changes of liposomes and lecithin in non-aqueous media

Radiation-induced changes of lipids in non-aqueous media were studied to elucidate the process of radiation damage in biological membranes. The lipid peroxidation progressed linearly with increasing dose and decreasing dose rate of γ-irradiation in soyabean lecithin in chloroform. The fatty acid composition of lecithin also changed, especially in linoleic and linolenic acids. Lower dose rate radiation enhanced these changes in oxic condition. Lipid peroxidation was also shown in lipids extracted from irradiated liposomes or in liposomes prepared from irradiated lecithin in chloroform. The dose-dependent glucose efflux was seen in liposomes prepared from irradiated lecithin in chloroform. These results indicate that the peroxidation of lipid molecules might cause radiation damage to the membrane conformation. (author)

Social perception about environmental problems and its associated risks can be a key factor for the success and acceptance of public policies aimed to environment protection and sustain ability. In that sense, the role of the mass media in generating the so-called environmental awareness is already an open question. Many of the last studies on media effects on public opinion have been carried out under the umbrella of Agenda Setting and Framing theories. According to Agenda Setting central hypothesis, relevant issues in media agenda will be also extended to public agenda. Framing theory holds that framing created by media can complete cognitive maps of people. Based on these theoretical approaches, the goal of this paper is to explore the media agenda of two Spanish national newspapers - EL PAIS and ABC with special attention to environmental issues. This report is based on the application of quantitative content and statistical analysis. Results indicate that there exists a very low level of press coverage dedicated to the environmental issue in media agenda. However, environment is ahead of issues such as technological risks and science and technology. Statistically significant differences have not been found in the press coverage each newspaper dedicates to environment, but these differences exist in other issues. (Author) 30 refs.

N ANALYSIS FOR THE DIFFERENCES IN QUALITY OF NEWS IN PRINTED and ELECTRONIC MEDIA and THE CONCEPT OF REALITY

Tugba AKDAL

2017-04-01

Full Text Available Electronic media occurs as a new journalism field that causes the change of traditional communication and journalism activities. The most important qualities that electronic media provides to journalism are these; speed, time and cost. Furthermore, with electronic media’s being part of journalism, the power balance has started to shift and as an ordinary individual the reader, got out of the passive formation of traditional printed press. As a consequence of this, electronic media which became an important part of everyday life and living habit, provided the transition of journalism activities to ordinary individuals from journalists that are the professionals of media and these ordinary individuals became both producers and the readers of the news. In addition to the qualifications that news and journalism gained from digital media, the changes about news’ quality show up as the topics of argue. The scantiness of editorial and legal inspections, the number of information source and reliability, the order of the stylistic form and inadequacy of content are the main problems about this issue. In this order that media professionalism is changing hands, these problem are possible because the reader happens to be the creator of the news. Yet, the question that how the conventional press organs maintain their journalism tendency and line which belong to their own for years in internet news is a different issue which must be analysed separately as a factor which affect the reader reliability and the perception of image directly. In this research, the question of where newspapers that are the traditional media devices leans on in both written and electronic environment is explored through the examination of headlines in both environments. In this aspect, 15 days-long written headlines of newspapers like Cumhuriyet and Hürriyet are examined in both environments in stylistic and contextual way and 100 news that are examined overall, are tabulated in

Diffusion Dominant Solute Transport Modelling In Deep Repository Under The Effect of Emplacement Media Degradation - 13285

International Nuclear Information System (INIS)

Kwong, S.; Jivkov, A.P.

2013-01-01

Deep geologic disposal of high activity and long-lived radioactive waste is being actively considered and pursued in many countries, where low permeability geological formations are used to provide long term waste contaminant with minimum impact to the environment and risk to the biosphere. A multi-barrier approach that makes use of both engineered and natural barriers (i.e. geological formations) is often used to further enhance the containment performance of the repository. As the deep repository system subjects to a variety of thermo-hydro-chemo-mechanical (THCM) effects over its long 'operational' lifespan (e.g. 0.1 to 1.0 million years, the integrity of the barrier system will decrease over time (e.g. fracturing in rock or clay)). This is broadly referred as media degradation in the present study. This modelling study examines the effects of media degradation on diffusion dominant solute transport in fractured media that are typical of deep geological environment. In particular, reactive solute transport through fractured media is studied using a 2-D model, that considers advection and diffusion, to explore the coupled effects of kinetic and equilibrium chemical processes, while the effects of degradation is studied using a pore network model that considers the media diffusivity and network changes. Model results are presented to demonstrate the use of a 3D pore-network model, using a novel architecture, to calculate macroscopic properties of the medium such as diffusivity, subject to pore space changes as the media degrade. Results from a reactive transport model of a representative geological waste disposal package are also presented to demonstrate the effect of media property change on the solute migration behaviour, illustrating the complex interplay between kinetic biogeochemical processes and diffusion dominant transport. The initial modelling results demonstrate the feasibility of a coupled modelling approach (using pore-network model and reactive

Changing Media Ecologies in Thailand: Women's Online Participation in the 2013/2014 Bangkok Protests

Directory of Open Access Journals (Sweden)

Olivia Guntarik

2016-12-01

Full Text Available Traditionally marginalized groups now have more access to new and unconventional means to participate in politics, transforming the media ecologies of existing political environments. Contemporary feminist scholarship has centered on how women use new media technologies to serve political agendas. However, this literature focuses predominately on women in the West, while women in developing countries, or Asia more generally, have been largely excluded from analysis. This article aims to fill in this gap by examining Thai women’s online activities during the 2013/2014 Bangkok political protests. Specifically, we ask how the rise of social and digital media has altered what it means to participate politically in the context of Thai women’s present-day political experience. To answer this question we looked at how women resorted to various digital and social media to discuss women’s rights and political issues, including Yingluck Shinawatra’s political leadership as Thailand’s first female prime minister (2011-2014. Moving beyond traditional notions of participation, we argue that there is a need to recognize the emerging dynamics of women’s online engagement in the political landscape of Thailand. In the context of a totalitarian state, speaking out against the ruling authority online embodies an additional layer of citizen resistance, a feature of digital life that is often taken for granted in Western democracies.

Climate Change, a Case Study of Media Construction of Environmental Problems; El Cambio Climatico como Casuistica de la Construccion Mediatica de los Problemas Medioambientales

Energy Technology Data Exchange (ETDEWEB)

Lopera, E.

2009-07-21

Nowadays climate change is one of the environmental problems in the global policy agenda. However, in countries like United States and United Kingdom the media started to report regularly on this issue in 1988. Since then many researches have been carrying out focused on how the media influence, along with other factors, public understanding of climate change through the media construction of the problem in several countries. Given the implications of social acceptance for design and implementation of public policies on mitigation and adaptation to climate change, the overall aim of this report is to review the status of the issue from a qualitative and quantitative approach. Qualitatively, media construction of climate change is described as the result of different processes taking place at macro and micro scales. Interactions among scientists, politicians, industry, the media themselves and the social context are considered macro-scale influences, while journalistic values and norms shape the media coverage of this environmental problem at micro-scale when media professionals report on climate change. From a quantitative point of view this paper also includes the evolution of newspaper coverage on climate change in Spain from 1996 to 2006 and these figures are compared to the results obtained in the United States and United Kingdom during the same period.

The correlation of the sociology of health, social ecology and media democracy is demonstrated in the study. In societies of today, the role of the media is unquestionable in disseminating information relating to health and the environment. According to Paragraph (1) of Article XXI of the Hungarian Constitution of 2011, everyone has the right to a healthy environment. An environmentalist media democracy may forward environmental justice, environmental education, and environmentalist economy, etc. All these are required in order to establish a society where the healthy environment is an objective value.

Preparing for climate change impacts in Norway's built environment

Robert Lisoe, K.; Aandahl, G.; Eriksen, S.; Alfsen, K.

2003-01-01

This paper provides an overview of the Norwegian climate policy and of the practical implications of preparing Norway for climate change, with special emphasis on the challenges confronting the built environment. Although the Norwegian government has been relatively proactive in instituting measures aimed at halting global climate change, less attention has been paid to the challenge of adapting to climate change. The global climate system is likely to undergo changes, regardless of the implementation of abatement policies under the Kyoto Protocol or other regimes. The full range of impacts resulting from these changes is still uncertain; however, it is becoming increasingly clear that adaptation to climate change is necessary and inevitable within several sectors. The potential impacts of climate change in the built environment are now being addressed. Both the functionality of the existing built environment and the design of future buildings are likely to be altered by climate change impacts, and the expected implications of these new conditions are now investigated. However, measures aimed at adjustments within individual sectors, such as altering the criteria and codes of practice for the design and construction of buildings, constitute only a partial adaptation to climate change. In order to adapt effectively, larger societal and intersectoral adjustments are necessary. (author)

In recent years, non-communicable diseases (NCDs) have become epidemic in Bangladesh. Behaviour changing interventions are key to prevention and management of NCDs. A great majority of people in Bangladesh have low health literacy, are less receptive to health information, and are unlikely to embrace positive health behaviours. Mass media campaigns can play a pivotal role in changing health behaviours of the population. This review pinpoints the role of mass media campaigns for NCDs and the challenges along it, whilst stressing on NCD preventive programmes (with the examples from different countries) to change health behaviours in Bangladesh. Future research should underpin the use of innovative technologies and mobile phones, which might be a prospective option for NCD prevention and management in Bangladesh.

A sense of change: media designers and artists communicating about complexity in social-ecological systems

Joost M. Vervoort

2014-09-01

Full Text Available To take on the current and future challenges of global environmental change, fostering a widespread societal understanding of and engagement with the complex dynamics that characterize interacting human and natural systems is essential. Current science communication methods struggle with a number of specific challenges associated with communicating about complex systems. In this study we report on two collaborative processes, a short workshop and longer course, that aimed to harness the insights of interactive media designers and artists to overcome these challenges. The two processes resulted in 86 new interactive media concepts which were selected by the participants and organizers using set criteria and then evaluated using the same criteria by a panel of communication and media design experts and a panel of complex systems scientists using the same criteria. The top eight concepts are discussed in this paper. These concepts fell into the categories of serious games, group interaction concepts, and social media storytelling. The serious games focused directly on complex systems characteristics and were evaluated to be intuitive and engaging designs that combined transparency and complexity well. The group interaction concepts focused mostly on feedbacks and nonlinearity but were fully developed and tested in the workshops, and evaluated as engaging, accessible, and easy to implement in workshops and educational settings. The social media storytelling concepts involved less direct interactions with system dynamics but were seen as highly accessible to large scale audiences. The results of this study show the potential of interdisciplinary collaboration between complex systems scientists, designers, and artists. The results and process discussed in this paper show the value of more structural engagement of interactive media designers and artist communities in the development of communication tools about human and natural systems change.

Full Text Available Organizations with activities of all kinds are influenced by environmental conditions, and external environment is in fact the beginning point of the strategy. Strategic management is an approach resulting from fast changing age and can consider it as a view and a technique for flexible planning to fast changes, and balanced score card is regarded as one of the strong instruments in this zone. Balanced score card can truly plays an important role in all stages of strategic management and the efficiency of this model is considerably regarded in management performance evaluation in different organizations. However, strong instrument such as balance score card is hardly used because of long term dominance of political approaches in the management of Iran media organizations. This paper conceptualizes administrational trend of strategic planning by implementing balanced score card and we draw strategy map and determine performance indexes in a written media organization (Hamshahri Newspaper.

2014-06-01

Full Text Available Changes in the South African media and management environment have had distinct influences on especially small to medium-sized mainstream media enterprises (media SMEs which often have to compete with bigger media organisations for the same news stories. Moreover, these media organisations are commonly faced with unique challenges related to human and other resources. This situation adds to the importance of effective and efficient management practices at these media sites. The management practices of first-line news managers in media SMEs are qualitatively and quantitatively evaluated in this paper by considering six managerial competencies found in general management theory. These competencies relate to communication, planning and administration, teamwork; strategic action, global awareness and self-management.

The Impact of Internet and Social Media on Kids’ and Parents’ Game Habits

Mustafa Akdag

2014-12-01

Full Text Available Internet, already a part of our lives far surpassing its limits as a means of communication, seems to have shaped most fields in human life and changed most of our daily habits and as a consequence the digital natives are observed to be completely living in Internet culture. One of the reflections of this culture and arenas in the Internet, social media has substantial impacts on gaming habits of digital natives. Up to the period in which Internet has interfered in man’s life, the games played by parents were passed from older generations to the new ones as a tradition, so generations used to play the same games; when the children of a previous era became parents they described the games they used to play to their kids thus paving the way to the sustainability of this game tradition. While different generations used to play the same games, today with the dissemination of Internet and social media caused a change of format in the traditionally played games and street games started to give their places to those played on the computers. Therefore, children started to play games on the Internet, an endless space whether negative or positive. The fact that parents are alienated from this arena, enabled the children to play violent games without any boundaries and to take place in social media arenas that could have negative impact on children’s worldly and spiritual well-being. The study is highly important in the sense that it clarifies the extent to which Internet and social media, which is actually the agent of change in children’s gaming habits, environments changed parents’ gaming habits among themselves and with their children. Surveys are conducted to the parents of primary school students as a field work to identify the changes originating from Internet and social media. According to research results, social media and Internet are found to be altering gaming habits of parents with their children. It is identified that parents keep

Full Text Available Mass communications play an important role in lifelong education. Therefore there is a need for formation of media and information literacy at students. The article also describes the features of the European approach to media and information literacy. The necessity of introduction of integrated media education in formal education for the development of metasubject skills needed for further learning and professional training throughout life. The following priority tasks of media education which are identified through experimental research are under discussion: formation of critical thinking, development of information security skills, ethics, etiquette, morality and responsibility. To implement an integrated media education, the strategic actions are: inclusion of the concept of “media education” or “media and information literacy” in the regulations for the formal education, a need to create media education environment as a part of education environment of education institutions, including media education training of students in activity of pedagogical institutions.

Changing the Rules of the Game: How Do We Measure Success in Social Media?

Hogan, Aisling M; Winter, Desmond C

Ours will be the generation proud to say we shifted the sands of educational deserts by open access and proliferation, seeding of data sharing, and watering grassroots research in resource-compromised environments. Universal "social" media is defining features of modern professional life that provide powerful modes of knowledge acquisition/sharing to that end. Altmetric and other measurements stratify academic communications according to this alternate, online media presence (not academic penetrance). Are they meaningless, self-absorbed integers, or reliable yardsticks of scientific and educational prowess? Far beyond this trite, patronizing question from the minds of outdated, terrified technophobes, the real impact of "social" media is not narcissistic solipsism. Instant dissemination of contemporary surgical controversies on a truly global level drives improved (or at least reflective) health care for all. While a numerical assignment of value according to views, "likes," impressions, or "retweets" may seem meaningless to cynical, established academics, the impetus for universal improvement is self-evident. Electronic data and opinion sharing may not balance the inequity between low- and high-income countries, but it keeps it in perspective. The best way to shift desert sands is to blow on them constantly.

Sudden transition and sudden change from open spin environments

We investigate the necessary conditions for the existence of sudden transition or sudden change phenomenon for appropriate initial states under dephasing. As illustrative examples, we study the behaviors of quantum correlation dynamics of two noninteracting qubits in independent and common open spin environments, respectively. For the independent environments case, we find that the quantum correlation dynamics is closely related to the Loschmidt echo and the dynamics exhibits a sudden transition from classical to quantum correlation decay. It is also shown that the sudden change phenomenon may occur for the common environment case and stationary quantum discord is found at the high temperature region of the environment. Finally, we investigate the quantum criticality of the open spin environment by exploring the probability distribution of the Loschmidt echo and the scaling transformation behavior of quantum discord, respectively. - Highlights: • Sudden transition or sudden change from open spin baths are studied. • Quantum discord is related to the Loschmidt echo in independent open spin baths. • Steady quantum discord is found in a common open spin bath. • The probability distribution of the Loschmidt echo is analyzed. • The scaling transformation behavior of quantum discord is displayed

Full Text Available Due to the turbulent and chaotic economic climate over the entire advertising industry, the TV stations, and particularly those in Romania, face a critical challenge in terms of dealing with an unprecedented crisis within this market. Since the last quarter of 2008, the Romanian advertising market is going through a serious phase of contraction and reconfiguration. One of the causes is the strong connection with the other similar markets within the Central and Eastern Europe, as well as with those from the West, which face the same decline. Several important publications were closed during 2009 and the beginning of 2010, together with higher unemployment in the media sector and major changes of the biggest media groups strategies. This paper aims to portrait the perspective of the TV Brand Managers in the center of a challenging environment, both in the organizations and in the overall market.

Generalized Optical Theorem Detection in Random and Complex Media

Science.gov (United States)

Tu, Jing

The problem of detecting changes of a medium or environment based on active, transmit-plus-receive wave sensor data is at the heart of many important applications including radar, surveillance, remote sensing, nondestructive testing, and cancer detection. This is a challenging problem because both the change or target and the surrounding background medium are in general unknown and can be quite complex. This Ph.D. dissertation presents a new wave physics-based approach for the detection of targets or changes in rather arbitrary backgrounds. The proposed methodology is rooted on a fundamental result of wave theory called the optical theorem, which gives real physical energy meaning to the statistics used for detection. This dissertation is composed of two main parts. The first part significantly expands the theory and understanding of the optical theorem for arbitrary probing fields and arbitrary media including nonreciprocal media, active media, as well as time-varying and nonlinear scatterers. The proposed formalism addresses both scalar and full vector electromagnetic fields. The second contribution of this dissertation is the application of the optical theorem to change detection with particular emphasis on random, complex, and active media, including single frequency probing fields and broadband probing fields. The first part of this work focuses on the generalization of the existing theoretical repertoire and interpretation of the scalar and electromagnetic optical theorem. Several fundamental generalizations of the optical theorem are developed. A new theory is developed for the optical theorem for scalar fields in nonhomogeneous media which can be bounded or unbounded. The bounded media context is essential for applications such as intrusion detection and surveillance in enclosed environments such as indoor facilities, caves, tunnels, as well as for nondestructive testing and communication systems based on wave-guiding structures. The developed scalar

2012-06-01

Full Text Available This paper explores the development and impact of the author’s TELE (Technology Enhanced Learning Environment action research project for individualising media practice education. The latest iteration of different classroom methodologies being employed to develop high-level skills in media production, the author has combined an interactive eLearning approach with instructional videos and, crucially, an individual feedback loop in order to widen access to the curriculum and create a more efficient teaching and learning environment. The focus therefore is on student engagement and organisational efficiencies as a result of the research. It should be noted that there has been no funding attached to this work, nor are there any institutional imperatives or other stakeholder involvement in this research. This project has been undertaken by the author as an evolutionary development of the various methodologies developed, cognisant of the increased technology literacy of the student cohort. The educational benefit of bringing video instruction into the curriculum as part of the project is examined as a creative pedagogy of direct benefit to students rather than as a subliminal marketing tool that other systems are often used for. Over 16K words of written data was collected during the project, and this is analysed both quantitatively and qualitatively with reference to the initial objectives of the research

Arab Media Discourse: Breaking Taboos

Directory of Open Access Journals (Sweden)

El Mustapha Lahlali

2016-01-01

Full Text Available This paper examines the development and change of Arab media discourse since mid-1990s. The paper looks at how the production and consumption of media discourse have changed dramatically in the Arab world over the last decade or so, notably in relation to taboos such as religion, governance and gender. The paper argues that transnational Arab media, particularly al-Jazeera, have contributed to this change by adopting a liberal and critical approach when dealing with Arab taboos. This change is clearly reflected in the new discourse adopted by both the Arab public and Arab media. Such a discourse practice shapes and is shaped by a new Arab social, cultural and political practice.

Liekweg, Kimberly; Christakis, Dimitri A.

2011-01-01

BACKGROUND: Media use has been shown to negatively affect a child's sleep, especially in the context of evening use or with a television in the child's bedroom. However, little is known about how content choices and adult co-use affect this relationship. OBJECTIVE: To describe the impact of media content, timing, and use behaviors on child sleep. METHODS: These data were collected in the baseline survey and media diary of a randomized controlled trial on media use in children aged 3 to 5 years. Sleep measures were derived from the Children's Sleep Habits Questionnaire. Media diaries captured time, content title, and co-use of television, video-game, and computer usage; titles were coded for ratings, violence, scariness, and pacing. Nested linear regression models were built to examine the impact of timing, content, and co-use on the sleep problem score. RESULTS: On average, children consumed 72.9 minutes of media screen time daily, with 14.1 minutes occurring after 7:00 pm. Eighteen percent of parents reported at least 1 sleep problem; children with a bedroom television consumed more media and were more likely to have a sleep problem. In regression models, each additional hour of evening media use was associated with a significant increase in the sleep problem score (0.743 [95% confidence interval: 0.373–1.114]), as was daytime use with violent content (0.398 [95% confidence interval: 0.121–0.676]). There was a trend toward greater impact of daytime violent use in the context of a bedroom television (P = .098) and in low-income children (P = .07). CONCLUSIONS: Violent content and evening media use were associated with increased sleep problems. However, no such effects were observed with nonviolent daytime media use. PMID:21708803

Asymmetric competition impacts evolutionary rescue in a changing environment.

Van Den Elzen, Courtney L; Kleynhans, Elizabeth J; Otto, Sarah P

2017-06-28

Interspecific competition can strongly influence the evolutionary response of a species to a changing environment, impacting the chance that the species survives or goes extinct. Previous work has shown that when two species compete for a temporally shifting resource distribution, the species lagging behind the resource peak is the first to go extinct due to competitive exclusion. However, this work assumed symmetrically distributed resources and competition. Asymmetries can generate differences between species in population sizes, genetic variation and trait means. We show that asymmetric resource availability or competition can facilitate coexistence and even occasionally cause the leading species to go extinct first. Surprisingly, we also find cases where traits evolve in the opposite direction to the changing environment because of a 'vacuum of competitive release' created when the lagging species declines in number. Thus, the species exhibiting the slowest rate of trait evolution is not always the most likely to go extinct in a changing environment. Our results demonstrate that the extent to which species appear to be tracking environmental change and the extent to which they are preadapted to that change may not necessarily determine which species will be the winners and which will be the losers in a rapidly changing world. © 2017 The Author(s).

An electrochemical approach to monitor pH change in agar media during plant tissue culture.

Science.gov (United States)

Wang, Min; Ha, Yang

2007-05-15

In this work, metal oxide microelectrodes were developed to monitor pH change in agar media during plant tissue culture. An antimony wire was produced by a new approach "capillary melt method". The surface of the obtained antimony wire was oxidized in a potassium nitrate melt to fabricate an antimony oxide film for pH sensing. Characterization results show that the oxide layer grown on the wire surface consists of Sb(2)O(3) crystal phase. The sensing response, open-circuit potential, of the electrode has a good linear relationship (R(2)=1.00) with pH value of the test solution. Adding organic compounds into the test media would not affect the linear relationship, although the slope of the lines varied with different ingredients added. The antimony oxide electrodes were employed to continuously monitor pH change of agar culture media during a 2-week plant tissue culture of Dendrobium candidum. The antimony oxide electrode fabricated this way has the advantages of low cost, easy fabrication, fast response, and almost no contamination introduced into the system. It would be suitable for in situ and continuous pH measurement in many bio applications.

Synthesis of iron oxide nanoparticles under oxidizing environment and their stabilization in aqueous and non-aqueous media

International Nuclear Information System (INIS)

Maity, D.; Agrawal, D.C.

2007-01-01

Synthesis of magnetite (Fe 3 O 4 ) nanoparticles under oxidizing environment by precipitation from aqueous media is not straightforward because Fe 2+ gets oxidized to Fe 3+ and thus the ratio of Fe 3+ :Fe 2+ =2:1 is not maintained during the precipitation. A molar ratio of Fe 3+ :Fe 2+ smaller than 2:1 has been used by many to compensate for the oxidation of Fe 2+ during the preparation. In this work, we have prepared iron oxide nanoparticles in air environment by the precipitation technique using initial molar ratios Fe 3+ :Fe 2+ ≤2:1. The phases of the resulting powders have been determined by several techniques. It is found that the particles consist mainly of maghemite with little or no magnetite phase. The particles have been suspended in non-aqueous and aqueous media by coating the particles with a single layer and a bilayer of oleic acid, respectively. The particle sizes, morphology and the magnetic properties of the particles and the ferrofulids prepared from these particles are reported. The average particle sizes obtained from the TEM micrographs are 14, 10 and 9 nm for the water, kerosene and dodecane-based ferrofluids, respectively, indicating a better dispersion in the non-aqueous media. The specific saturation magnetization (σ s ) value of the oleic-acid-coated particles (∼53 emu/g) is found to be lower than that for the uncoated particles (∼63 emu/g). Magnetization σ s of the dodecane-based ferrofluid is found to be 10.1 emu/g for a volume fraction of particles φ=0.019. Zero coercivity and zero remanance on the magnetization curves indicate that the particles are superparamagnetic (SPM) in nature

Full Text Available Asia has some of the largest, most dynamic, diversified, and complicated media industries in the world (McKinsey & Company, 2015. Entering the 21st Century, the rapid economic and political developments of Asia further energize the growth of media locally and globally (for general discussion, see, e.g., Keane [2006]; Thussu [2006], specific discussions on the cases of Korea [Kim, 2013], Japan [Iwabuchi, 2004], China [Sun, 2009]. In a reflection on the increasing importance of Asian players in global communication industry, Keane describes that “Asianness is colonizing international communications markets” (2006: 839-840 with the impacts ranging from the production of hardware (i.e., East Asian technology to content (e.g., Japanese manga, anime and TV formats and South Korean popular culture and from the cross-over of directors and actors from Asia to Hollywood and the world. Yet, a lack of timely understanding of media and communication in a fast-changing Asia is hindering not only our interpretation of the significance of media in social transformation in Asia, but also the efforts to de-westernize (e.g., Park & Curran, 2000; Wang, 2010 or internationalize communication studies (Lee, 2014.

2013-07-01

Social media has emerged as a popular mode of communication, with more than 73% of the teenage and adult population in the United States using it on a regular basis [Lenhart et al., 2010]. Young people in particular (ages 12-29) are deeply involved in the rapidly evolving social media environment and have an expectation of communication through these media. This engagement creates a valuable opportunity for scientific organizations and programs to use the wide reach, functionality, and informal environment of social media to create brand recognition, establish trust with users, and disseminate scientific information.

Quick-change filter cartridge

Rodgers, John C.; McFarland, Andrew R.; Ortiz, Carlos A.

1995-01-01

A quick-change filter cartridge. In sampling systems for measurement of airborne materials, a filter element is introduced into the sampled airstream such that the aerosol constituents are removed and deposited on the filter. Fragile sampling media often require support in order to prevent rupture during sampling, and careful mounting and sealing to prevent misalignment, tearing, or creasing which would allow the sampled air to bypass the filter. Additionally, handling of filter elements may introduce cross-contamination or exposure of operators to toxic materials. Moreover, it is desirable to enable the preloading of filter media into quick-change cartridges in clean laboratory environments, thereby simplifying and expediting the filter-changing process in the field. The quick-change filter cartridge of the present invention permits the application of a variety of filter media in many types of instruments and may also be used in automated systems. The cartridge includes a base through which a vacuum can be applied to draw air through the filter medium which is located on a porous filter support and held there by means of a cap which forms an airtight seal with the base. The base is also adapted for receiving absorbing media so that both particulates and gas-phase samples may be trapped for investigation, the latter downstream of the aerosol filter.

Media Effects: Theory and Research.

This review analyzes trends and commonalities among prominent theories of media effects. On the basis of exemplary meta-analyses of media effects and bibliometric studies of well-cited theories, we identify and discuss five features of media effects theories as well as their empirical support. Each of these features specifies the conditions under which media may produce effects on certain types of individuals. Our review ends with a discussion of media effects in newer media environments. This includes theories of computer-mediated communication, the development of which appears to share a similar pattern of reformulation from unidirectional, receiver-oriented views, to theories that recognize the transactional nature of communication. We conclude by outlining challenges and promising avenues for future research.

Notes on Narrative as Medium and a Media Ecology Approach to the Study of Storytelling

Directory of Open Access Journals (Sweden)

Lance Strate

2014-11-01

Full Text Available Storytelling, as a distinctively human characteristic, is a product of our capacity for language and symbolic communication. Just as language is considered a medium within the field of media ecology, so too can narrative be understood as a medium of communication, as well as a kind of language, and as a fundamentally social phenomenon. As a medium, narrative interacts with and is modified by other media, undergoing significant change as it is expressed through oral tradition, dramatic performance, written documents, and audiovisual media. In particular, major changes in the nature of character and plot accompany the shift from orality to literacy, and writing and especially printing make possible new forms of tragedy as opposed to comedy, prose as opposed to poetry, and fiction as opposed to nonfiction. Storytelling continues to mutate through the introduction of new media, with increasingly greater emphasis on narrative as an environment, especially one associated with social interaction and gaming.

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.

The predicted future of the global marine environment, as a combined result of forcing due to climate change (e.g. warming and acidification) and other anthropogenic perturbation (e.g. eutrophication), presents a challenge to the sustainability of ecosystems from tropics to high latitudes. Among the various associated phenomena of ecosystem deterioration, hypoxia can cause serious problems in coastal areas as well as oxygen minimum zones in the open ocean (Diaz and Rosenberg 2008 Science 321 926-9, Stramma et al 2008 Science 320 655-8). The negative impacts of hypoxia include changes in populations of marine organisms, such as large-scale mortality and behavioral responses, as well as variations of species distributions, biodiversity, physiological stress, and other sub-lethal effects (e.g. growth and reproduction). Social and economic activities that are related to services provided by the marine ecosystems, such as tourism and fisheries, can be negatively affected by the aesthetic outcomes as well as perceived or real impacts on seafood quality (STAP 2011 (Washington, DC: Global Environment Facility) p 88). Moreover, low oxygen concentration in marine waters can have considerable feedbacks to other compartments of the Earth system, like the emission of greenhouse gases to the atmosphere, and can affect the global biogeochemical cycles of nutrients and trace elements. It is of critical importance to prediction and adaptation strategies that the key processes of hypoxia in marine environments be precisely determined and understood (cf Zhang et al 2010 Biogeosciences 7 1-24).

Polymedia and Ethnography: Understanding the Social in Social Media

2015-04-01

Full Text Available In this essay I argue that social media need to be understood as part of complex environments of communicative opportunities which I conceptualize as polymedia. This approach shifts our attention from social media as discrete platforms to the ways users navigate environments of affordances in order to manage their social relationships. Ethnography emerges as the most appropriate method to capture the relational dynamics that underpin social media practices within polymedia.

From “the end of advertising as we know it” to “beyond content”? Changes in advertising and the impact on journalistic media

OpenAIRE

Siegert, Gabriele

2013-01-01

The advertising industry and the media industry have long been tied together to reach their main objectives. The advertising industry used media as ad vehicles to embed and transport their ad messages and the media needed advertising money to finance and subsidize their activities. Additionally the advertising income of media outlets depends on economic changes – be they cyclical or structural. Journalistic media seem to be more affected by cyclical downturns than other media types, and th...

Gomes, Alexandra W; Butera, Gisela; Chretien, Katherine C; Kind, Terry

2017-01-01

Inappropriate social media behavior can have detrimental effects on students' future opportunities, but medical students are given little opportunity to reflect upon ways of integrating their social media identities with their newly forming professional identities. In 2012, a required educational session was developed for 1st-year medical students on social media and professional identity. Objectives include identifying professionalism issues and recognizing positive social media use. The 2-hour large-group session uses student-generated social media examples to stimulate discussion and concludes with an expert panel. Students complete a postsession reflection assignment. The required social media session occurs early in the 1st year and is part of the Professionalism curriculum in The George Washington University School of Medicine. Reflection papers are graded for completion. The study began in 2012 and ran through 2014; a total of 313/505 participants (62%) volunteered for the study. Assessment occurred through qualitative analysis of students' reflection assignments. Most students (65%, 203/313) reported considering changes in their social media presence due to the session. The analysis revealed themes relating to a broader understanding of online identity and opportunities to enhance careers. In a 6-month follow-up survey of 76 students in the 2014 cohort who completed the entire survey, 73 (94%) reported some increase in awareness, and 48 (64%) made changes to their social media behavior due to the session (response rate = 76/165; 46%), reflecting the longer term impact. Opportunities for discussion and reflection are essential for transformational learning to occur, enabling understanding of other perspectives. Incorporating student-submitted social media examples heightened student interest and engagement. The social media environment is continually changing, so curricular approaches should remain adaptable to ensure timeliness and relevance. Including

Adaptation, plasticity, and extinction in a changing environment: towards a predictive theory.

Directory of Open Access Journals (Sweden)

Luis-Miguel Chevin

2010-04-01

Full Text Available Many species are experiencing sustained environmental change mainly due to human activities. The unusual rate and extent of anthropogenic alterations of the environment may exceed the capacity of developmental, genetic, and demographic mechanisms that populations have evolved to deal with environmental change. To begin to understand the limits to population persistence, we present a simple evolutionary model for the critical rate of environmental change beyond which a population must decline and go extinct. We use this model to highlight the major determinants of extinction risk in a changing environment, and identify research needs for improved predictions based on projected changes in environmental variables. Two key parameters relating the environment to population biology have not yet received sufficient attention. Phenotypic plasticity, the direct influence of environment on the development of individual phenotypes, is increasingly considered an important component of phenotypic change in the wild and should be incorporated in models of population persistence. Environmental sensitivity of selection, the change in the optimum phenotype with the environment, still crucially needs empirical assessment. We use environmental tolerance curves and other examples of ecological and evolutionary responses to climate change to illustrate how these mechanistic approaches can be developed for predictive purposes.

The social determinants of substance abuse in African American baby boomers: effects of family, media images, and environment.

2010-07-01

Grounded theory methodology was used to explore the social processes involved in the use of illicit drugs in older African Americans as an underpinning to the development of approaches to nursing care and treatment. Interviews were conducted with six older African American substance users who were currently in drug treatment programs. Responses to the questions were recorded, transcribed, and analyzed using constant comparative methods. Three core themes emerged: (a) family, (b) media images, and (c) environment. The core issues of substance abuse, such as the environment and larger societal forces, cannot be addressed by one discipline and mandate that clinicians move to an interdisciplinary approach to achieve a plan of care for this growing population.

Yang, Xiaohui; Zhu, Liqi

2016-12-01

We examined predictors of media multitasking in Chinese adolescents from 3 contexts: characteristics of the media user, types of media use and family media contexts. Three hundred and twenty adolescents, 11-18 years of age, completed questionnaires to measure media use, impulsivity, sensation seeking, time management disposition and family media environment. The results showed that media multitasking was positively correlated with age and total media use time. Participants with high levels of impulsivity and sensation seeking reported more multitasking behaviour. Multitasking was negatively correlated with time management. Children from media-oriented families often engage in more multitasking. What's more, social networking sites use and music use can mediate the effect of individual and family factors on media multitasking. © 2015 International Union of Psychological Science.

Climate Education Partners (CEP) uses an action research approach to increase climate knowledge and informed decision-making among key influential (KI) leaders in San Diego county. Social media has been one method for disseminating knowledge. During CEP's project years, social media use has proliferated. To capitalize on this trend, CEP iteratively developed a strategic method to engage KIs. First, as with all climate education, CEP identified the audience. Three primary Facebook and Twitter audiences were CEP's internal team, local KIs, and strategic partner organizations. Second, post contents were chosen based on interest to CEP key audiences and followed CEP's communications message triangle, which incorporates the Tripartite Integration Model of Social Influence (TIMSI). This message triangle focuses on San Diegan's valued quality of life, future challenges we face due to the changing climate, and ways in which we are working together to protect our quality of life for future generations. Third, an editorial calendar was created to carefully time posts, which capitalize on when target audiences were using social media most and to maintain consistency. The results of these three actions were significant. Results attained utilizing Facebook and Twitter data, which tracks post reach, total followers/likes, and engagement (likes, comments, mentions, shares). For example we found that specifically mentioning KIs resulted in more re-tweets and resulted in reaching a broader audience. Overall, data shows that CEP's reach to audiences of like-minded individuals and organizations now extends beyond CEP's original local network and reached more than 20,000 accounts on Twitter this year (compared with 460 on Twitter the year before). In summary, through posting and participating in the online conversation strategically, CEP disseminated key educational climate resources and relevant climate change news to educate and engage target audience and amplify our work.

Full Text Available The graphic arts and media sector has been affected by technological developments, particularly in the last years of the 20th century. These developments mainly affect the traditional graphic arts companies which aim at pre-press and printing production processes and workflow. Furthermore, changes are taking place in the entire range of the media industry where the traditional graphic arts sector belongs.Because of these developments, the graphic arts and media sector as well as the print media will need to be reorientated. One of the principal components related to the existence and further development of companies are the employees: that is people and individuals that have any kind of professional relationship with the graphic arts and media sector.The changes in the production environment and the application of new technologies and workflows have led to the increase in the importance of education and training as one of the fundamental factors for sector development.This paper investigates the characteristics of print media within the new structure of the media industry and their relationship to the new electronic processes. Furthermore, the current structure and reform strategies that has been applied in education and training, mainly in European Union countries, is explored. As for the further development of the graphic arts and media sector, a new strategy concerning the future structure of education and training is discussed and suggested. This strategy is based on the development of a transnational educational training system for the graphic arts and media sector at a European level.

Including Media in Field Research and Becoming Part of the Science Media

Pelto, M. S.

2015-12-01

There are two primary strategies that I have pursued over the last decade to engage the media, policy makers, and public; after two decades of typical scientific publication methods. An effective method to engage the media with our ongoing 32 year glacier field research program has been to invite media members to join us in the field. From climate videographers to traditional reporters we have had a member of the media with us in nine of the last ten field seasons; two in 2015. The resulting stories have led to several awards for the journalists and an ongoing relationship with our research program. The second part of this science research communication strategy is to have readily available material on specific topics for the media to utilize; this requires social media outreach. The primary outlet media find is the AGU Blog: From a Glacier's Perspective. This blog pubishes two articles a week on a specific glacier's response to climate change. The blog yields on average a media contact on every fourth blog post in 2015. The contacts revolve around specific local glacier information published on the blog. The goal of each blog post is to tell a story about how each glacier is impacted by climate change.

A Cultural Evolution Approach to Digital Media.

Science.gov (United States)

Acerbi, Alberto

2016-01-01

Digital media have today an enormous diffusion, and their influence on the behavior of a vast part of the human population can hardly be underestimated. In this review I propose that cultural evolution theory, including both a sophisticated view of human behavior and a methodological attitude to modeling and quantitative analysis, provides a useful framework to study the effects and the developments of media in the digital age. I will first give a general presentation of the cultural evolution framework, and I will then introduce this more specific research program with two illustrative topics. The first topic concerns how cultural transmission biases, that is, simple heuristics such as "copy prestigious individuals" or "copy the majority," operate in the novel context of digital media. The existence of transmission biases is generally justified with their adaptivity in small-scale societies. How do they operate in an environment where, for example, prestigious individuals possess not-relevant skills, or popularity is explicitly quantified and advertised? The second aspect relates to fidelity of cultural transmission. Digitally-mediated interactions support cheap and immediate high-fidelity transmission, in opposition, for example, to oral traditions. How does this change the content that is more likely to spread? Overall, I suggest the usefulness of a "long view" to our contemporary digital environment, contextualized in cognitive science and cultural evolution theory, and I discuss how this perspective could help us to understand what is genuinely new and what is not.

Full Text Available Storytelling is old, but in our digital age its means are new. When an event of huge cultural significance occurs (such as the sinking of the Costa Concordia, the “Occupy Wall Street” Protest, or the coming of Boat-People to Europe stories ricochet from TV to Internet, from cell phone to text message with a speed and proliferation unknown even a decade ago. We need new and effective ways to understand the making of cultural processes in a multi-media environment in order to learn and develop strategies to make sense of cultural shifts in a reduced and very limited span of time. My essay draws on research in both Memory Studies, Literary Studies and Media Ecology to open up the study of storytelling to old and new media psycho-dynamics so to start to develop a methodology of investigation that will facilitate a deeper understanding of the role of multimedia storytelling in the ways in which both individuals and groups cognitively and emotionally navigate profound cultural shift, as well as in the ways in which they create and preserve their memories through time and technological change.

European media systems have gone through major changes in the last few decades, and these changes have included increased opportunity structures for the dissemination of populist messages. Chapter 12 (‘Switzerland’) rightly states that the disappearance of the traditional party press, increased...... media ownership concentration, dependence on advertising, and a stronger orientation toward news values have worked in favor of a growing populist discourse. The newly established online media are seen as having a high afnity to populism’s rhetorical persuasion because both aim for the “quick kick....../click” with a broad audience. As was stated in Chapter 1 in this volume, the role that the media play in the dissemination of populism is largely under-explored.

Social media public health campaigns have the advantage of tailored messaging at low cost and large reach, but little is known about what would determine their feasibility as tools for inducing attitude and behavior change. The aim of this study was to test the feasibility of designing, implementing, and evaluating a social media-enabled intervention for skin cancer prevention. A quasi-experimental feasibility study used social media (Twitter) to disseminate different message "frames" related to care in the sun and cancer prevention. Phase 1 utilized the Northern Ireland cancer charity's Twitter platform (May 1 to July 14, 2015). Following a 2-week "washout" period, Phase 2 commenced (August 1 to September 30, 2015) using a bespoke Twitter platform. Phase 2 also included a Thunderclap, whereby users allowed their social media accounts to automatically post a bespoke message on their behalf. Message frames were categorized into 5 broad categories: humor, shock or disgust, informative, personal stories, and opportunistic. Seed users with a notable following were contacted to be "influencers" in retweeting campaign content. A pre- and postintervention Web-based survey recorded skin cancer prevention knowledge and attitudes in Northern Ireland (population 1.8 million). There were a total of 417,678 tweet impressions, 11,213 engagements, and 1211 retweets related to our campaign. Shocking messages generated the greatest impressions (shock, n=2369; informative, n=2258; humorous, n=1458; story, n=1680), whereas humorous messages generated greater engagement (humorous, n=148; shock, n=147; story, n=117; informative, n=100) and greater engagement rates compared with story tweets. Informative messages, resulted in the greatest number of shares (informative, n=17; humorous, n=10; shock, n=9; story, n=7). The study findings included improved knowledge of skin cancer severity in a pre- and postintervention Web-based survey, with greater awareness that skin cancer is the most

Social media in the promotion of health.

Matikainen, Janne; Huovila, Janne

Social media has brought about a major change in communication. Besides ordinary people, the change applies to organizations and public authorities. In the social media, the public becomes an active player and content provider. With social media, communication will become increasingly media-centered. The change in communication scenery has challenged traditional expertise. On the other hand, social media also opens up many possibilities for the establishment of expertise and health communication. Within the social media, communities can become significant sites for the production of knowledge and expertise. They may generate useful activity as regards the combination of health information activities and everyday life, but sometimes they can also become a cradle of false information. In its various forms, social media provides a versatile forum for health communication, where people can be met interactively.

Utilizing the social media data to validate 'climate change' indices

Science.gov (United States)

Molodtsova, T.; Kirilenko, A.; Stepchenkova, S.

2013-12-01

Reporting the observed and modeled changes in climate to public requires the measures understandable by the general audience. E.g., the NASA GISS Common Sense Climate Index (Hansen et al., 1998) reports the change in climate based on six practically observable parameters such as the air temperature exceeding the norm by one standard deviation. The utility of the constructed indices for reporting climate change depends, however, on an assumption that the selected parameters are felt and connected with the changing climate by a non-expert, which needs to be validated. Dynamic discussion of climate change issues in social media may provide data for this validation. We connected the intensity of public discussion of climate change in social networks with regional weather variations for the territory of the USA. We collected the entire 2012 population of Twitter microblogging activity on climate change topic, accumulating over 1.8 million separate records (tweets) globally. We identified the geographic location of the tweets and associated the daily and weekly intensity of twitting with the following parameters of weather for these locations: temperature anomalies, 'hot' temperature anomalies, 'cold' temperature anomalies, heavy rain/snow events. To account for non-weather related events we included the articles on climate change from the 'prestige press', a collection of major newspapers. We found that the regional changes in parameters of weather significantly affect the number of tweets published on climate change. This effect, however, is short-lived and varies throughout the country. We found that in different locations different weather parameters had the most significant effect on climate change microblogging activity. Overall 'hot' temperature anomalies had significant influence on climate change twitting intensity.

Astronomical Ice: The Effects of Treating Ice as a Porous Media on the Dynamics and Evolution of Extraterrestrial Ice-Ocean Environments

Science.gov (United States)

Buffo, J.; Schmidt, B. E.

2015-12-01

With the prevalence of water and ice rich environments in the solar system, and likely the universe, becoming more apparent, understanding the evolutionary dynamics and physical processes of such locales is of great importance. Piqued interest arises from the understanding that the persistence of all known life depends on the presence of liquid water. As in situ investigation is currently infeasible, accurate numerical modeling is the best technique to demystify these environments. We will discuss an evolving model of ice-ocean interaction aimed at realistically describing the behavior of the ice-ocean interface by treating basal ice as a porous media, and its possible implications on the formation of astrobiological niches. Treating ice as a porous media drastically affects the thermodynamic properties it exhibits. Thus inclusion of this phenomenon is critical in accurately representing the dynamics and evolution of all ice-ocean environments. This model utilizes equations that describe the dynamics of sea ice when it is treated as a porous media (Hunke et. al. 2011), coupled with a basal melt and accretion model (Holland and Jenkins 1999). Combined, these two models produce the most accurate description of the processes occurring at the base of terrestrial sea ice and ice shelves, capable of resolving variations within the ice due to environmental pressures. While these models were designed for application to terrestrial environments, the physics occurring at any ice-water interface is identical, and these models can be used to represent the evolution of a variety of icy astronomical bodies. As terrestrial ice shelves provide a close analog to planetary ice-ocean environments, we truth test the models validity against observations of ice shelves. We apply this model to the ice-ocean interface of the icy Galilean moon Europa. We include profiles of temperature, salinity, solid fraction, and Darcy velocity, as well as temporally and spatially varying melt and

Birthweight and placental weight; do changes in culture media used for IVF matter? Comparisons with spontaneous pregnancies in the corresponding time periods.

2013-12-01

Have changes in culture media used for IVF resulted in changes in offspring birthweight or placental weight that differed from the trends in offspring from spontaneous conceptions during the corresponding time periods? Changes in culture media used for IVF were associated with significant differences in offspring birthweight and in placental weight to birthweight ratio when compared with the trend in offspring from spontaneous conceptions during the time periods. The effect of culture media used for IVF on offspring birthweight has varied between studies. There is a large variation in birthweight between newborns, and birthweight may vary across populations and over time. Such variations may therefore have influenced previous results. We included all singleton births from IVF at one treatment center in Norway during the years 1999-2011(n = 2435) and all singleton births from spontaneous conceptions in Norway during the same years (n = 698 359). Three different media were used for embryo culture; Medicult Universal IVF (1999 through 2007, n = 1584), Medicult ISM1 (2008 until 20 September 2009, n = 402) and Vitrolife G-1 PLUS (21 September 2009 through 2011, n = 449). We estimated mean birthweight and placental weight in IVF pregnancies by culture media. We also estimated mean weights in IVF and in spontaneous pregnancies by year of birth. Thereafter, we studied whether the changes in mean weights in IVF pregnancies differed from the changes in weight in spontaneous pregnancies in the periods corresponding to culture media changes by applying a grouped difference-in-difference analysis. Adjustments were made for parity, maternal age and gestational age at birth. In singleton offspring from IVF the mean birthweight was 3447.6 g with Medicult Universal, 3351.7 g with Medicult ISM1 and 3441.4 g with Vitrolife G-1 PLUS (P ISM1 (P = 0.16) and increased with 79.9 g by the change from Medicult ISM1 to Vitrolife G-1 PLUS (P = 0.01) when compared with changes in offspring

Particularly it concentrates on the analysis of internet and daily press usage. Internet is a constantly developing communication channel which is increasingly used in the field of marketing communication and contributes to the development of business environment. Due to its characteristics it is an ideal mean for multilingual communication and communication on international markets. The daily press is on the other hand a representative of traditional media. It is perceived by public as a more natural communication channel. The paper seeks an answer to the question which communication channel is more suitable to communicate with a particular target group – press or the internet. The paper tests the correlation between identification factors and frequency of internet and press presence. Testing will be carried out by using a database obtained in a primary research conducted by the Department of Marketing and Trade at the Faculty of Business and Economics, Mendel University in Brno.

2013-01-01

The predicted future of the global marine environment, as a combined result of forcing due to climate change (e.g. warming and acidification) and other anthropogenic perturbation (e.g. eutrophication), presents a challenge to the sustainability of ecosystems from tropics to high latitudes. Among the various associated phenomena of ecosystem deterioration, hypoxia can cause serious problems in coastal areas as well as oxygen minimum zones in the open ocean (Diaz and Rosenberg 2008 Science 321 926–9, Stramma et al 2008 Science 320 655–8). The negative impacts of hypoxia include changes in populations of marine organisms, such as large-scale mortality and behavioral responses, as well as variations of species distributions, biodiversity, physiological stress, and other sub-lethal effects (e.g. growth and reproduction). Social and economic activities that are related to services provided by the marine ecosystems, such as tourism and fisheries, can be negatively affected by the aesthetic outcomes as well as perceived or real impacts on seafood quality (STAP 2011 (Washington, DC: Global Environment Facility) p 88). Moreover, low oxygen concentration in marine waters can have considerable feedbacks to other compartments of the Earth system, like the emission of greenhouse gases to the atmosphere, and can affect the global biogeochemical cycles of nutrients and trace elements. It is of critical importance to prediction and adaptation strategies that the key processes of hypoxia in marine environments be precisely determined and understood (cf Zhang et al 2010 Biogeosciences 7 1–24).

Accelerated climate change causes disasters and disrupts people living all over the globe. Disruptive climate events are often reflected in expressed sentiments of the people affected. Monitoring changes in these sentiments during and after disasters can reveal relationships between climate change and mental health. We developed a semantic web tool that uses linked data principles and semantic web technologies to integrate data from multiple sources and analyze them together. We are converting statistical data on climate change and disaster records obtained from the World Bank data catalog and the International Disaster Database into a Resource Description Framework (RDF) representation that was annotated with the RDF Data Cube vocabulary. We compare these data with a dataset of tweets that mention terms from the Emotion Ontology to get a sense of how disasters can impact the affected populations. This dataset is being gathered using an infrastructure we developed that extracts term uses in Twitter with controlled vocabularies. This data was also converted to RDF structure so that statistical data on the climate change and disasters is analyzed together with sentiment data. To visualize and explore relationship of the multiple data across the dimensions of time and location, we use the qb.js framework. We are using this approach to investigate the social and emotional impact of climate change. We hope that this will demonstrate the use of social media data as a valuable source of understanding on global climate change.

Science Express: Out-of-Home-Media to Communicate Climate Change (Invited)

Lustick, D. S.; Lohmeier, J.; Chen, R.

2013-12-01

Science Express is an initiative to explore, develop, and test various approaches to using Out-of-Home-Media (OHM) to engage adults riding mass transit. To date, three projects represent this work: 1) Carbon Smarts Conference, 2) Cool Science, and 3) ScienceToGo.org. While the aim of each project is different, together they serve an immediate need to understand how OHM can be leveraged as an informal science learning medium. Using Climate Change as the content focus, each project is a variation on the theme of understanding mass transit as a form of mobile classroom for riders. The basic idea behind these initiatives is to engage individuals who do not necessarily read the science magazines, listen to science radio shows, or watch science programming on television. Science Express is about bringing the science learning opportunity to the audience during their daily routines. Mass Transit provides an ideal opportunity for engaging the disengaged in science learning since they represent a ';captive' audience while waiting at the bus stop, standing on the platform, riding inside the bus or train. These ';downtimes' present informal science educators with the opportunity to foster some science learning. With the advent of smartphone technology and its explosion in popularity among consumers, OHM is poised to offer riders a new kind of real time learning experience. The Science Express projects aim to understand the strengths and weaknesses of this new model for informal science learning so as to refine and improve its effectiveness at achieving desired goals. While the Science Express model for informal science learning could be used to foster understanding about any relevant scientific content, the research team chose to use Climate Change as the focus. Climate Change seemed like an obvious because of its timeliness, complexity, robust scientific foundation, and presence in popular media. Nearly all our riders have heard of 'Climate Change' or 'Global Warming', but a

Little is known about whether the childhood family psychosocial environment (characterized by cold, unaffectionate interactions, conflict, aggression, neglect and/or low nurturance) affects coronary heart disease (CHD) risk. Objectives were to evaluate associations of childhood family psychosocial environment with carotid intima media thickness (IMT), a subclinical measure of atherosclerosis. The study population included 2659 CARDIA study participants, aged 37-52 years. Childhood family psychosocial environment was measured using a risky family questionnaire via self-report. Carotid IMT was calculated using the average of 20 measurements of mean common carotid, bulb and internal carotid IMT, assessed using high-resolution B-mode ultrasound images. Utilizing linear regression analyses adjusted for age, a 1-unit (range 0-21) increase in risky family score was associated with 0.0036 (95% CI: 0.0006,0.0066 mm) and 0.0020 (95% CI: 0.0002,0.0038) mm increase in mean IMT in white males and females, respectively. Formal mediation analyses and covariate adjustments suggested childhood socioeconomic position and smoking may be important mechanisms in white males and females, as well as education and depressive symptomatology in white males. No associations were found in black participants. Formal statistical tests for interaction between risky family score and sex, and between risky family score and race/ethnicity, demonstrated borderline evidence of interactions for both sex (p = 0.12) and race/ethnicity (p = 0.14) with risky family score for associations with mean IMT. In conclusion, childhood family psychosocial environment was positively associated with IMT in white participants, with little evidence of association in black participants. Mechanisms in white participants may include potential negative impacts of socioeconomic constraints on parenting quality, potentially influencing offspring's cardiovascular risk factors (e.g. smoking), socioeconomic position (e

Full Text Available The changes that are happening in businesses dictate the changes in all kinds of needed resources to develop the organization. The environment in which the organizations operate is in constant change and becomes more and more unpredictable. Managing these changes is a challenge that all enterprises face. The rapid changes that are happening in business are increasing the need to manage these changes. Enterprises have to develop and use different kinds of management models so that they can grow their performance in order to ensure a competitive position in the market. The changes in enterprises sometimes are not accepted by the organization employees, and seem to have negative effects towards them (exemption from work, reduction of working hours, reduction of income. Changes have negative and positive effects. Successful and rational managers can achieve having successful changes and minimizing the negative effects that come due to changes. Changes are vital for organizations so that they can replace the old plans and models with new and successful ones. In this paper we talk about the role and importance of managing the changes, the types of changes, models of changes, the resistance against changes and also the obtained results of the paper are introduced. Literature was used to support the research in the study field, and based on that to explain the role of changes in the business environment. There are quantitative methods and an inductive analysis used in this paper.

PERSPECTIVE: Climate change: seeking balance in media reports

emissions to ultimately stabilise the climate at safe levels, then it is essential that those involved in climate change research keep a careful note of the portrayal of their research in the media. Boykoff and Mansfield (2008) (and citations therein) make an important contribution to this process. Ultimately, of course, (for predictions corresponding to different prescribed emissions scenarios) we are working with an issue embedded in fundamental science. If newspapers and books take a sceptical angle, and through this force further reductions in uncertainty bounds surrounding available scientific understanding, then such reporting will have played a useful role, even if ultimately shown to be incorrect. But such refinement has to happen quickly—if a global consensus emerges, unchallenged, that climate change issues are being vastly overplayed (or worse are almost some form of hoax) then we could be 'sleep walking' towards eventual climatic disaster as a consequence of a 'business as usual' attitude to emissions. We believe the current debate to be vital. But ultimately, society requires a balanced presentation of the facts. It is unreasonable to expect the tabloid media to avoid oversimplification and sensational comments, but it is reasonable and necessary in support of the political process to present a balanced view, and to avoid systematic misrepresentation of the science in either direction. We believe the IPCC goes a long way towards achieving this—but there is still much to do. References Booker B and North R 2007 Scared to Death.

Quesnel, Kimberly J; Ajami, Newsha K

2017-10-01

Public awareness of water- and drought-related issues is an important yet relatively unexplored component of water use behavior. To examine this relationship, we first quantified news media coverage of drought in California from 2005 to 2015, a period with two distinct droughts; the later drought received unprecedentedly high media coverage, whereas the earlier drought did not, as the United States was experiencing an economic downturn coinciding with a historic presidential election. Comparing this coverage to Google search frequency confirmed that public attention followed news media trends. We then modeled single-family residential water consumption in 20 service areas in the San Francisco Bay Area during the same period using geospatially explicit data and including news media coverage as a covariate. Model outputs revealed the factors affecting water use for populations of varying demographics. Importantly, the models estimated that an increase of 100 drought-related articles in a bimonthly period was associated with an 11 to 18% reduction in water use. Then, we evaluated high-resolution water consumption data from smart meters, known as advanced metering infrastructure, in one of the previously modeled service areas to evaluate breakpoints in water use trends. Results demonstrated that whereas nonresidential commercial irrigation customers responded to changes in climate, single-family residential customers decreased water use at the fastest rate following heavy drought-related news media coverage. These results highlight the need for water resource planners and decision makers to further consider the importance of effective, internally and externally driven, public awareness and education in water demand behavior and management.

The growing use of social media is transforming the way health care professionals (HCPs) are communicating. In this changing environment, it could be useful to outline the usage of social media by radiologists in all its facets and on an international level. The main objective of the RANSOM survey was to investigate how radiologists are using social media and what is their attitude towards them. The second goal was to discern differences in tendencies among American and European radiologists. An international survey was launched on SurveyMonkey ( https://www.surveymonkey.com ) asking questions about the platforms they prefer, about the advantages, disadvantages, and risks, and about the main incentives and barriers to use social media. A total of 477 radiologists participated in the survey, of which 277 from Europe and 127 from North America. The results show that 85 % of all survey participants are using social media, mostly for a mixture of private and professional reasons. Facebook is the most popular platform for general purposes, whereas LinkedIn and Twitter are more popular for professional usage. The most important reason for not using social media is an unwillingness to mix private and professional matters. Eighty-two percent of all participants are aware of the educational opportunities offered by social media. The survey results underline the need to increase radiologists' skills in using social media efficiently and safely. There is also a need to create clear guidelines regarding the online and social media presence of radiologists to maximize the potential benefits of engaging with social media.

Estimating the Importance of Social Media in Consumers’ Education

Full Text Available The social media is composed of easily accessible web tools through which people converse, participate, create, recommend, valorify information and respond online to everything that happens around them. These web tools offer a dynamic virtual environment where users are engaged in a continuous traffic generated by information and interactivity. Internet development and access to information led to a change in consumer behavior in Romania. In this context, it must be taken into account that the buying decision and the decision to include certain foods in daily diet is significantly influenced by the views and experiences of other consumers, expressed in the virtual environment. Thus a new communication channel provided by the internet through social media (forums, chat, blogs, sites reviews appeared. In this respect, we conducted a research - using the main search engines – with the aim to analyze the evolution of the number of forums and blogs, and also of the posts on these, related to the words bio-eggs, eggs from battery raised chickens and eggs numbering, during December 2009 – June 2010.

Testing take-the-best in new and changing environments.

Lee, Michael D; Blanco, Gabrielle; Bo, Nikole

2017-08-01

Take-the-best is a decision-making strategy that chooses between alternatives, by searching the cues representing the alternatives in order of cue validity, and choosing the alternative with the first discriminating cue. Theoretical support for take-the-best comes from the "fast and frugal" approach to modeling cognition, which assumes decision-making strategies need to be fast to cope with a competitive world, and be simple to be robust to uncertainty and environmental change. We contribute to the empirical evaluation of take-the-best in two ways. First, we generate four new environments-involving bridge lengths, hamburger prices, theme park attendances, and US university rankings-supplementing the relatively limited number of naturally cue-based environments previously considered. We find that take-the-best is as accurate as rival decision strategies that use all of the available cues. Secondly, we develop 19 new data sets characterizing the change in cities and their populations in four countries. We find that take-the-best maintains its accuracy and limited search as the environments change, even if cue validities learned in one environment are used to make decisions in another. Once again, we find that take-the-best is as accurate as rival strategies that use all of the cues. We conclude that these new evaluations support the theoretical claims of the accuracy, frugality, and robustness for take-the-best, and that the new data sets provide a valuable resource for the more general study of the relationship between effective decision-making strategies and the environments in which they operate.

Water Cycle Dynamics in a Changing Environment: Advancing Hydrologic Science through Synthesis

Sivapalan, M.; Kumar, P.; Rhoads, B. L.; Wuebbles, D.

2007-12-01

As one ponders a changing environment -- climate, hydrology, land use, biogeochemical cycles, human dynamics -- there is an increasing need to understand the long term evolution of the linked component systems (e.g., climatic, hydrologic and ecological) through conceptual and quantitative models. The most challenging problem toward this goal is to understand and incorporate the rich dynamics of multiple linked systems with weak and strong coupling, and with many internal variables that exhibit multi-scale interactions. The richness of these interactions leads to fluctuations in one variable that in turn drive the dynamics of other related variables. The key question then becomes: Do these complexities lend an inherently stochastic character to the system, rendering deterministic prediction and modeling of limited value, or do they translate into constrained self- organization through which emerges order, and a limited group of "active" processes (that may change from time to time) that determine the general evolution of the system through a series of structured states with a distinct signature? This is a grand challenge for predictability and therefore requires community effort. The interconnectivity and hence synthesis of knowledge across the fields should be natural for hydrologists since the global water cycle and its regional manifestations directly correspond to the information flows for mass and energy transformations across the media, and across the disciplines. Further, the rich history of numerical, conceptual and stochastic modeling in hydrology provides the training and breadth for addressing the multi- scale, complex system dynamics challenges posed by the evolution question. Theory and observational analyses that necessitate stepping back from the existing knowledge paradigms and looking at the integrated system are needed. In this talk we will present the outlines of a new NSF-funded community effort that attempts to forge inter- disciplinary

Feature Optimization for Long-Range Visual Homing in Changing Environments

Directory of Open Access Journals (Sweden)

Qidan Zhu

2014-02-01

Full Text Available This paper introduces a feature optimization method for robot long-range feature-based visual homing in changing environments. To cope with the changing environmental appearance, the optimization procedure is introduced to distinguish the most relevant features for feature-based visual homing, including the spatial distribution, selection and updating. In the previous research on feature-based visual homing, less effort has been spent on the way to improve the feature distribution to get uniformly distributed features, which are closely related to homing performance. This paper presents a modified feature extraction algorithm to decrease the influence of anisotropic feature distribution. In addition, the feature selection and updating mechanisms, which have hardly drawn any attention in the domain of feature-based visual homing, are crucial in improving homing accuracy and in maintaining the representation of changing environments. To verify the feasibility of the proposal, several comprehensive evaluations are conducted. The results indicate that the feature optimization method can find optimal feature sets for feature-based visual homing, and adapt the appearance representation to the changing environments as well.

The goal of this article is to describe the broad curricular constructs surrounding teaching and learning about social media in dental education. This analysis takes into account timing, development, and assessment of the knowledge, skills, attitudes, and behaviors needed to effectively use social media tools as a contemporary dentist. Three developmental stages in a student's path to becoming a competent professional are described: from undergraduate to dental student, from the classroom and preclinical simulation laboratory to the clinical setting, and from dental student to licensed practitioner. Considerations for developing the dental curriculum and suggestions for effective instruction at each stage are offered. In all three stages in the future dentist's evolution, faculty members need to educate students about appropriate professional uses of social media. Faculty members should provide instruction on the beneficial aspects of this communication medium and help students recognize the potential pitfalls associated with its use. The authors provide guidelines for customizing instruction to complement each stage of development, recognizing that careful timing is not only important for optimal learning but can prevent inappropriate use of social media as students are introduced to novel situations.

The DIII-D Computing Environment: Characteristics and Recent Changes

The DIII-D tokamak national fusion research facility along with its predecessor Doublet III has been operating for over 21 years. The DIII-D computing environment consists of real-time systems controlling the tokamak, heating systems, and diagnostics, and systems acquiring experimental data from instrumentation; major data analysis server nodes performing short term and long term data access and data analysis; and systems providing mechanisms for remote collaboration and the dissemination of information over the world wide web. Computer systems for the facility have undergone incredible changes over the course of time as the computer industry has changed dramatically. Yet there are certain valuable characteristics of the DIII-D computing environment that have been developed over time and have been maintained to this day. Some of these characteristics include: continuous computer infrastructure improvements, distributed data and data access, computing platform integration, and remote collaborations. These characteristics are being carried forward as well as new characteristics resulting from recent changes which have included: a dedicated storage system and a hierarchical storage management system for raw shot data, various further infrastructure improvements including deployment of Fast Ethernet, the introduction of MDSplus, LSF and common IDL based tools, and improvements to remote collaboration capabilities. This paper will describe this computing environment, important characteristics that over the years have contributed to the success of DIII-D computing systems, and recent changes to computer systems

Connected Activism: Indigenous Uses of Social Media for Shaping Political Change

Directory of Open Access Journals (Sweden)

Marisa Elena Duarte

2017-07-01

Full Text Available Prior studies describe digital tactics as specific strategies actors apply within broader repertoires of contention, specifically in social and political contexts. A comparison of EZLN, Idle No More, and the ongoing Rio Yaqui water rights movement reveals the kinds of community knowledge work that has to happen prior to and around activating digital tactics in Indigenous rights movements, including choices in messaging and discourses of Indigeneity, targeting of movement opponents, and selection of digital tools and techniques. Activists harness these communicative affordances to practice a politics of visibility, cultivate solidarity, diffuse an Indigenous consciousness, enforce dominant governments’ trust and treaty responsibilities, and remind many of the irrevocable injustice of colonialism. Designing methodologies that account for specific Indigenous social and political contexts as well as the affordances of various digital environments is part of the future work of Indigenous media theorists.

Freeman, Becky; Potente, Sofia; Rock, Vanessa; McIver, Jacqueline

2015-03-30

A great deal of enthusiasm and interest exists in using social media for public health communications, but few research studies have examined its success in promoting and adopting protective health behaviours. To begin to understand how best to develop effective online social marketing campaigns, this paper provides a summary of success factors and key lessons learnt from selected social media campaign case studies. Case study review Methods: A selection of case studies was reviewed for lessons in campaign development, delivery and evaluation from both the corporate and public health sectors. Information about the objective of the campaign, the tactics used and the lessons learnt was extracted from each case study. Lessons learnt from across the case studies were then sorted according to themes. Lessons from the nine case studies selected were categorised into eight themes: planning, use of social media tools, community, content, personal benefits, promotion, costs and challenges. Outcome evaluation data were lacking in the case studies. Overall, the nine case studies show that social media hold promise in changing user behaviours and that social media are highly effective in recruiting participants and motivating them to take small, concrete actions. The case studies also demonstrate that there is room in social media for targeted, inexpensive, small-scale projects, as well as large, well-funded, mass-reach marketing blitzes. Social media campaign process and impact evaluation measures are readily available. Outcome evaluation models and measures are needed to better assess the effectiveness of social media campaigns in changing health behaviours.

Human activities and climate and environment changes: an inevitable relation

International Nuclear Information System (INIS)

Sanchez, Aretha

2009-01-01

The human interference in the environment and the consequent climate change is today a consensus. The climate change can be local, regional and global. The global climate change is mainly caused by the greenhouse gases, and consequently the climate change intervenes in the environment. The interference cycle emerges in several forms and results in several consequences. However, the Global Warming has certainly the most import global impact. The main cause of the increase in the temperature (Greenhouse Effect) is the intensive use of the fossil fuels. Thus, to minimize the climatic changes actions are necessary to reduce, to substitute and to use with more efficient the fossil fuels. Looking at the past, the old agriculturists may have released greenhouse gases since thousand years ago, thus, modifying slowly but in significant form the earth climate much before the Industrial Age. If this theory is confirmed, its consequences would be decisive for the man history in the planet. For example, in parts of the North America and Europe the current temperatures could be even four Celsius degrees smaller. This change in temperature is enough to hinder agricultural used of these regions and consequently to diminish the human development. The main focus of this work is to perform a retrospective in some of civilizations who collapse due to environmental problems and make a historical description of the human activities (agriculture and livestock) since the primordium of the man up to the Industrial Age, aiming at the man interference on the natural dynamics of the global climate and the environment. This work will show through data comparisons and inferences that the gases emissions from these activities had a significant magnitude comparatively by the emissions after the Industrial Age. It is also demonstrated that the climate and environment interference was inevitable because the human evolution was caused by these activities. Another important point of this work is to

Media Literacy in Montenegro

Full Text Available Few countries in the world have introduced media education into their curriculums. Montenegro became one of them in 2009, when “media literacy” was introduced as an optional subject for 16 and 17 year old students of Gymnasium high schools. This article presents the findings of the first and only research conducted so far on media education in Montenegro. It is a national case study which examines the potential of media education to change the school culture and accelerate education system reform towards embracing the new digital education paradigm in the future. The focus is on the results of research conducted through in-depth interviews with media literacy teachers all over the country. Despite the many challenges, all teachers identify the potential of media education to strengthen some of the key competences of the students and to improve their motivation and academic performance. They also identify potential to change positively school culture by transforming teachers into “cultural mediators” (Morcellini, 2007 and by supporting the formation of a “participative culture” (Jenkins & Kelley, 2013 in schools. This research recommends focusing education reform on spreading the media education pedagogy to the entire curriculum in order to embrace the new digital education paradigm in the future.

Full Text Available The present paper aims at exploring the potential role that social media technologies play in learning foreign languages. For this purpose, a survey was carried out to examine students’ and language learners’ perceptions and attitudes about using these platforms. Results of the research study revealed that the great majority of the respondents actually use these web-based applications to enhance their language skills. Most importantly, they noted that social media contribute in improving their listening, reading, speaking and writing skills. Accordingly, we strongly recommend that instructors use these online tools in distant, blended, or face-to-face language learning settings.

Full Text Available In this paper, we explore the benefits of using social media in an online educational setting, with a particular focus on the use of Facebook and Twitter by participants in a Massive Open Online Course (MOOC developed to enable educators to learn about the Carpe Diem learning design process. We define social media as digital social tools and environments located outside of the provision of a formal university-provided Learning Management System. We use data collected via interviews and surveys with the MOOC participants as well as social media postings made by the participants throughout the MOOC to offer insights into how participants’ usage and perception of social media in their online learning experiences differed and why. We identified that, although some participants benefitted from social media by crediting it, for example, with networking and knowledge-sharing opportunities, others objected or refused to engage with social media, perceiving it as a waste of their time. We make recommendations for the usage of social media for educational purposes within MOOCs and formal digital learning environments.

2017-09-01

Social media encompasses computer-mediated technologies that facilitate the creation and sharing of information, ideas, and other forms of expression via virtual communities and networks. The key, of course, is the ability and willingness for information to be shared. But why does some information spread on social media and not others? What factors translate social media awareness to action? In this article, we explore these themes using case studies, as well as tips on how you can utilize social media to effectively champion a cause.

Changes seen in the environment report from Uusimaa Regional Environment Centre

2002-05-01

This publication describes the environmental changes and the influencing factors occurring within the administrative regions of the Uusimaa Regional Environment Centre. The quality of the environment can be judged as satisfying in regards to both the mental and physical health of humans. Areas have a steady trend of a relatively high growth in population density, while the efficiency of land use in new settlements is low. Traffic and the travel distances are on the rise. A considerable part of the population lives in areas where the noise standards are violated, despite control measures. Waste management, water distribution and sewage networks are under continuous development. In regards to the nature, the situation in some parts is of great concern. The manifold of the nature, cultural landscapes and culturally valuable buildings and sites are threatened. The living space of flora and fauna is continuing to decrease and change. The risks caused by human activities in groundwater areas are increasing. For these reasons the implementation of protection programs is important. Emissions from point sources to the water and air have significantly decreased. Yet, the impacts of air quality deprivation can still be seen in some cities and in the vicinity of some industrial sites. The eutrophication have essentially changed the ecology and fishstocks; however, the water quality has improved in many places. Regarding the above issues, as well as some other topics, included in the report are 16 theme maps 66 pictures. However, the report states that the monitoring and reporting of the environmental quality should be improved. (orig.)

Wade, Tracey D; Wilksch, Simon M; Paxton, Susan J; Byrne, Susan M; Austin, S Bryn

2017-07-01

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.

2017-04-01

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.

Change in ocean subsurface environment to suppress tropical cyclone intensification under global warming

Science.gov (United States)

Huang, Ping; Lin, I. -I; Chou, Chia; Huang, Rong-Hui

2015-01-01

Tropical cyclones (TCs) are hazardous natural disasters. Because TC intensification is significantly controlled by atmosphere and ocean environments, changes in these environments may cause changes in TC intensity. Changes in surface and subsurface ocean conditions can both influence a TC's intensification. Regarding global warming, minimal exploration of the subsurface ocean has been undertaken. Here we investigate future subsurface ocean environment changes projected by 22 state-of-the-art climate models and suggest a suppressive effect of subsurface oceans on the intensification of future TCs. Under global warming, the subsurface vertical temperature profile can be sharpened in important TC regions, which may contribute to a stronger ocean coupling (cooling) effect during the intensification of future TCs. Regarding a TC, future subsurface ocean environments may be more suppressive than the existing subsurface ocean environments. This suppressive effect is not spatially uniform and may be weak in certain local areas. PMID:25982028

Takahashi, Bruno

2011-07-01

Studies about mass media framing have found divergent levels of influence on public opinion; moreover, the evidence suggests that issue attributes can contribute to this difference. In the case of climate change, studies have focused exclusively on developed countries, suggesting that media influence perceptions about the issue. This study presents one of the first studies of media coverage in a developing country. It examines newspapers' reporting in Peru during the Fifth Latin America, Caribbean and European Union Summit in May 2008. The study focuses on the frames and the sources to provide an initial exploratory assessment of the coverage. The results show that the media relied mostly on government sources, giving limited access to dissenting voices such as environmentalists. Additionally, a prominence of "solutions" and "effects" frames was found, while "policy" and "science" frames were limited. The results could serve as a reference point for more comprehensive studies.

Obesity and the built environment: changes in environmental cues cause energy imbalances.

Science.gov (United States)

Cohen, D A

2008-12-01

The past 30 years have seen dramatic changes in the food and physical activity environments, both of which contribute to the changes in human behavior that could explain obesity. This paper reviews documented changes in the food environment, changes in the physical activity environment and the mechanisms through which people respond to these environments, often without conscious awareness or control. The most important environmental changes have been increases in food accessibility, food salience and decreases in the cost of food. The increases in food marketing and advertising create food cues that artificially stimulate people to feel hungry. The existence of a metabolic pathway that allows excess energy to be stored as fat suggests that people were designed to overeat. Many internal mechanisms favor neurophysiologic responses to food cues that result in overconsumption. External cues, such as food abundance, food variety and food novelty, cause people to override internal signals of satiety. Other factors, such as conditioning and priming, tie food to other desirable outcomes, and thus increase the frequency that hunger is stimulated by environmental cues. People's natural response to the environmental cues are colored by framing, and judgments are flawed and biased depending on how information is presented. People lack insight into how the food environment affects them, and subsequently are unable to change the factors that are responsible for excessive energy consumption. Understanding the causal pathway for overconsumption will be necessary to interrupt the mechanisms that lead to obesity.

Does media governance restrict corporate overinvestment behavior? Evidence from Chinese listed firms

Directory of Open Access Journals (Sweden)

Huili Zhang

2015-03-01

Full Text Available Using China’s A-share listed firms from 2007 to 2011, this paper empirically tests how media governance affects firms’ levels of overinvestment and whether external supervision and informal institutional mechanisms reduce these levels. We find that media governance and overinvestment are significantly negatively related. When firms are located in a district with a stronger media governance environment their levels of overinvestment are lower, indicating that media governance significantly restricts overinvestment behavior. When internal corporate governance efficiency is low, the negative relationship between the media environment and overinvestment behavior is significantly enhanced, indicating that when internal governance or formal systems have reduced efficacy, an important complementary role is played by external supervision and the informal institutional environment. After considering endogeneity and different measures of overinvestment and other related variables, the conclusions remain unchanged.

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. The interactive features of the internet seemingly imply that online media have more advantages than traditional media forms (old media. So, the internet have dramatically evolved become new media with characteristic multimedia, hypertext, interactivity, archives , and virtuality. The most important structural new media characteristic is the integration of telecommunications, data communications and mass communication in a single medium – it is the convergence. It should be pointed out that the trend toward digital is affecting the various media and brings the local media in East Java to become a global media, where breaking news from Surabaya or anywhere in East Java is transmitted to around the world in a matter of minutes .

2011-12-01

In the context of a globalised world, reports on health that extend personal or country borders have increasing relevance. Media can promote opportunities to identify and address gaps in important global health issues. In light of the potential role of media as an advocacy tool for global health, we examined how global health issues are represented in mainstream media in New Zealand. We conducted a content analysis of media reports on global health issues in the four highest circulation newspapers in New Zealand between June 2007 and May 2009. Search terms included 'global health, 'international health' and 'world health'. Communicable disease was the most frequently reported global health issue in New Zealand newspapers, followed by environment (e.g. climate change), general health risks (unsafe pharmaceuticals) and substance use (tobacco and alcohol). Chronic disease, injury or their determinants were less frequently reported. Mainstream media favours health-related reports based on crisis, epidemic or acute conditions over chronic or non-communicable diseases or disability. Health issues facing the Asia Pacific region increasingly include chronic diseases, which would benefit from greater media coverage to increase advocacy and political awareness of global health challenges.

Mediamorphosis and misinformation in the infosphere: media, digital and information literacy face of changes in information consumption habits

2015-04-01

Full Text Available From a theoretical reflection, this work is evidence that the current communicational and digital ecosystem is endogenous and systemically misinformative, as it has gradually become an information overload and infoxicative scenario, traversed by a dynamic of mediamorphosis, in which traditional media are looking to compete for the preference of the audience facing the multiplicity of digital platforms in the way of their economic subsistence, usually spreading pseudo-contents with limbic great value, but lacking useful in the process of decision making. Consequently, this paper analyzes the above problems by reviewing various multidisciplinary academic contributions to later refer those from within the theories of media, digital and information literacy contribute recommendations and pragmatic schemes to cope with the situation. The work focuses on media-digital society in the context of media convergence and multiple screens, outlining the social changes that are currently embedded audiences. Obtained results showed the need to adapt an “infodiet” or media ecology from the user’s perspective, alternating moments of disconnection, without deserting the efforts that Educommunication and communication policy could contribute in social transformation, in order promote educational, cultural and informative content from the perspective of pluralism, citizen participation and pragmatic reconstruction towards public service media.

2018-05-01

The gate system is used to estimate the direction of RFID tags carriers when they are going through the gate. Normally, it is difficult to achieve and keep a high accuracy in estimating motion direction of RFID tags because the received signal strength of tag changes sharply according to the changing electromagnetic environment. In this paper, a method of motion direction estimation for RFID tags is presented. To improve estimation accuracy, the machine leaning algorithm is used to get the fitting function of the received data by readers which are deployed inside and outside gate respectively. Then the fitted data are sampled to get the standard vector. We compare the stand vector with template vectors to get the motion direction estimation result. Then the corresponding template vector is updated according to the surrounding environment. We conducted the simulation and implement of the proposed method and the result shows that the proposed method in this work can improve and keep a high accuracy under the condition of the constantly changing environment.

Perceived social and media influences on tobacco use among Samoan youth.

McCool, Judith; Freeman, Becky; Tanielu, Helen

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

Media coverage of climate change in Russia: governmental bias and climate silence.

Science.gov (United States)

Poberezhskaya, Marianna

2015-01-01

This paper explores which actors and factors influence media coverage of climate change in Russia. It does this by analysing the coverage of three events by five Russian national newspapers (Komsomol'skaya pravda, Rossiyskaya gazeta, Izvestiya, Kommersant and Sovetskaya Rossiya). The three events are the Kyoto Conference in 1997, the Copenhagen Conference in 2009 and the Russian heat-wave of 2010. This paper concludes that regardless of the ownership structure of the newspapers or their dependence on advertising, there is little difference in quantity and quality of overall coverage on climate change. With most newspapers relying on Russian officials as information sources, almost none criticise or question Russian climate policy. Furthermore, the article concludes that, in Russia, the omission of climate change issues from discussion in national newspapers becomes a greater problem than biased coverage, as the lack of commentary decidedly prevents these issues from entering the public debate. © The Author(s) 2014.

Due to the widespread use of silver nanoparticles (AgNPs), the likelihood of them entering the environment has increased and they are known to be potentially toxic. Currently, there is little information on the dynamic changes of AgNPs in ecotoxicity exposure media and how this may affect toxicity. Here, the colloidal stability of three different sizes of citrate-stabilized AgNPs was assessed in standard strength OECD ISO exposure media, and in 2-fold (media2) and 10-fold (media10) dilutions by transmission electron microscopy (TEM) and atomic force microscopy (AFM) and these characteristics were related to their toxicity towards Daphnia magna. Aggregation in undiluted media (media1) was rapid, and after diluting the medium by a factor of 2 or 10, aggregation was reduced, with minimal aggregation over 24h occurring in media10. Acute toxicity measurements were performed using 7nm diameter particles in media1 and media10. In media10 the EC50 of the 7nm particles for D. magna neonates was calculated to be 7.46μgL(-1) with upper and lower 95% confidence intervals of 6.84μgL(-1) and 8.13μgL(-1) respectively. For media1, an EC50 could not be calculated, the lowest observed adverse effect concentration (LOAEC) of 11.25μgL(-1) indicating a significant reduction in toxicity compared to that in media10. The data suggest the increased dispersion of nanoparticles leads to enhanced toxicity, emphasising the importance of appropriate media composition to fully assess nanoparticle toxicity in aquatic ecotoxicity tests.

Changing the Environment Based on Empowerment as Intrinsic Motivation

Directory of Open Access Journals (Sweden)

Christoph Salge

2014-05-01

Full Text Available One aspect of intelligence is the ability to restructure your own environment so that the world you live in becomes more beneficial to you. In this paper we investigate how the information-theoretic measure of agent empowerment can provide a task-independent, intrinsic motivation to restructure the world. We show how changes in embodiment and in the environment change the resulting behaviour of the agent and the artefacts left in the world. For this purpose, we introduce an approximation of the established empowerment formalism based on sparse sampling, which is simpler and significantly faster to compute for deterministic dynamics. Sparse sampling also introduces a degree of randomness into the decision making process, which turns out to beneficial for some cases. We then utilize the measure to generate agent behaviour for different agent embodiments in a Minecraft-inspired three dimensional block world. The paradigmatic results demonstrate that empowerment can be used as a suitable generic intrinsic motivation to not only generate actions in given static environments, as shown in the past, but also to modify existing environmental conditions. In doing so, the emerging strategies to modify an agent’s environment turn out to be meaningful to the specific agent capabilities, i.e., de facto to its embodiment.

Full Text Available Purpose. The aim of the work is to determine the features of media culture that bind it with mass culture and mass communications and have the most significant effect on the general principles of the religious mass communication. In addition, the objective is to identify the skills system and traits of mass human that are necessary for using media culture. Methodology. The methodological basis is related to structuring, analytical analysis and synthesis of media features; highlighting phenomena that illustrate modern communicative situation; characteristics of media trends influence for the specific functioning of religious communication. Scientific novelty. Main part of the work is devoted to the analysis of the progressive media culture, mass-media and their main features, design of religious communication in this culture. Media gradually form the appearance of religious communication quietly, especially the mass one, they adapt the modern religious discourse to rates of transfer and perception of information. Modern believer gets a lot of different kinds of religious information, on any subject, any explanation of the religious question, with respect to any religion. Such volume of religious information and the speed with which a person receives it, does not usually make it religious or spiritually advanced, but only informed. Spiritual perfection and religious development, religious communication is possible only when the customer is aware of media culture and way of seeing the ultimate goal of such communications using the Mass Media. So far these mechanisms are perfectly designed in traditional religious communication. Phenomena, that reflects the dramatic changes in the communicative environment are: mediatization of body and mind, the new practice of processing / reading information, the phenomenon of simultaneous perception of a large number of information channels – similar or different. Features of media culture that connect it with

This investigation was aimed to study the effect of contrast media on the cardiovascular system. So in this study, pithed rats were used whether alteration in cardiovascular system by contrast media were controlled centrally. Furthermore, several hypertonic solutions were also used to clarify the effect of contrast media. The results are as follows: 1. Intravenous injection of contrast media in rats (2.5 ml/kg) caused hypotension and bradycardia. The effects were neither blocked by pretreatment of atropine nor pyribenzamine+atropine. 2. NaCI 4.7%, dextrose 24.8%, urea 9.0% and glycerol 10.1% (v/v) which were equiosmolar with contrast media, caused hypotension, but did not affect the heart rate. 3. In pithed rats, intravenous injection of Angiografin increased blood pressure in a dose-dependant manner, and caused decrease in heart rate compared with those of control rats. 4. In pithed rats, bradycardia by intravascular injection with Angiografin was partially blocked by atropine. 5. Metrizamide of which iodine content was adjusted to 280 mg/ml caused increased in blood pressure when was injected intravenously in pithed rats with little effect on heart rate. 6. When perfused with contrast media in rat hindlimb at 15 ml/min./kg speed both perfusion pressure and flow effluent increased, simultaneously. These results suggest that hypotension might be caused by the central effect due to hyperosmolarity of contrast media and bradycardia caused by both parasympathetic stimulation and direct inhibitory action on the cardiac conductive system.

Adoption of Social Media for Public Relations by Museums

Full Text Available Conceptual evolution of the Internet and Web, substantiated through Web 2.0 and the emergence of online social networks, reinvented the way that enterprises interact with their customers. Museums, as cultural institutions with an important mission, are not unaffected by that change, however. In order to fulfil their duties and societal purpose successfully, they have to attract visitors’ attention and engage the public effectively in a highly competitive and saturated environment. The goal of this paper is to analyze and compare the social media presence of museums in two European capitals. It focuses on museums in Prague and Berlin, and considers their general Web presence and the dynamics of activities on Facebook. In order to understand the integrative social media approach of museums in both regions, we investigated additionally Twitter and Youtube presence among museums with a Facebook account. The study reveals a lower presence of Prague museums both on the Web and in the identified social media networks, in comparison to Berlin museums. Moreover, we conclude that the presence of both regional museums on social media networks is low, while the integration and simultaneous application of more networks at the same time are negligible, both for Prague and Berlin museums.

Delivering risk information in a dynamic information environment: Framing and authoritative voice in Centers for Disease Control (CDC) and primetime broadcast news media communications during the 2014 Ebola outbreak.

During a disease outbreak, media serve as primary transmitters of information from public health agencies to the public, and have been shown to influence both behavior and perception of risk. Differences in news frequency, framing and information source can impact the public's interpretation of risk messages and subsequent attitudes and behaviors about a particular threat. The media's framing of an outbreak is important, as it may affect both perception of risk and the ability to process important health information. To understand how risk communication by the Centers for Disease Control and Prevention (CDC) during the 2014 Ebola outbreak was framed and delivered and to what extent primetime broadcast news media mirrored CDC's framing and authoritative voice, 209 CDC communications and primetime broadcast transcripts issued between July 24 and December 29, 2014 were analyzed and coded by thematic frame and authoritative voice. Dominant frame and voice were determined for each month and for overall period of analysis. Medical frame was dominant in CDC (60%), Anderson Cooper 360 (49%), The Rachel Maddow Show (47%) and All In with Chris Hayes (47%). The human interest frame was dominant in The Kelly File (45%), while The O'Reilly Factor coverage was equally split between sociopolitical and medical frames (28%, respectively). Primetime news media also changed dominant frames over time. Dominant authoritative voice in CDC communications was that of CDC officials, while primetime news dominantly featured local and federal (non-CDC) government officials and academic/medical experts. Differences in framing and delivery could have led the public to interpret risk in a different way than intended by CDC. Overall, public health agencies should consider adapting risk communication strategies to account for a dynamic news environment and the media's agenda. Options include adapting communications to short-form styles and embracing the concept of storytelling. Copyright © 2016

Background Social media public health campaigns have the advantage of tailored messaging at low cost and large reach, but little is known about what would determine their feasibility as tools for inducing attitude and behavior change. Objective The aim of this study was to test the feasibility of designing, implementing, and evaluating a social media–enabled intervention for skin cancer prevention. Methods A quasi-experimental feasibility study used social media (Twitter) to disseminate different message “frames” related to care in the sun and cancer prevention. Phase 1 utilized the Northern Ireland cancer charity’s Twitter platform (May 1 to July 14, 2015). Following a 2-week “washout” period, Phase 2 commenced (August 1 to September 30, 2015) using a bespoke Twitter platform. Phase 2 also included a Thunderclap, whereby users allowed their social media accounts to automatically post a bespoke message on their behalf. Message frames were categorized into 5 broad categories: humor, shock or disgust, informative, personal stories, and opportunistic. Seed users with a notable following were contacted to be “influencers” in retweeting campaign content. A pre- and postintervention Web-based survey recorded skin cancer prevention knowledge and attitudes in Northern Ireland (population 1.8 million). Results There were a total of 417,678 tweet impressions, 11,213 engagements, and 1211 retweets related to our campaign. Shocking messages generated the greatest impressions (shock, n=2369; informative, n=2258; humorous, n=1458; story, n=1680), whereas humorous messages generated greater engagement (humorous, n=148; shock, n=147; story, n=117; informative, n=100) and greater engagement rates compared with story tweets. Informative messages, resulted in the greatest number of shares (informative, n=17; humorous, n=10; shock, n=9; story, n=7). The study findings included improved knowledge of skin cancer severity in a pre- and postintervention Web-based survey

The Greek media and the Kosovo crisis

Full Text Available The NATO air attacks (24/3/99-10/6/99 as an instrument of force against Serbia to terminate the abuse of the Albanian population in Kosovo, albeit supported by a significant part of the international community, were received much differently in Greece. Key to the climate of strong disagreement with the campaign was the role of the Greek media. The true reason behind the offensive was, according to them, the change in the geopolitical map to the advantage of the West, and in particular the USA. The underlying argument of this paper is that in the Kosovo crisis the media, Greek (and international, projected their own environment. It is particularly apt to examine the Greek case because of its very unique perspective that differentiated the coverage in Greece - a NATO member country - from the overall world media view. Also, the discussion is pertinent because Greek media coverage disagreed with the official government position, which although advocating a diplomatic resolution of the crisis, had to support the Alliance's decision to bomb Serbia. Furthermore, study of this case is significant because the clash of the Greek media view with the mainstream pro-NATO coverage found in many other countries generated negative views on Greece and its media on the international level. An examination of media content reveals that despite any differences concerning political or other factors, and regardless of the variations in the phrasing of the anti-NATO arguments, the overall media perspective exhibited a unanimous opposition to the bombing campaign. By placing the emphasis more or less on the same thematic areas as the world media, but by crucially reversing the line of reasoning (e.g. the refugee problem was blamed on the NATO bombing raids and not on Serbian atrocities, the Greek media invariably remained anti-war, anti-NATO and anti-Albanian in many particular cases, and in principle pro-Serb throughout.

Huang, Camillan

2003-01-01

Technology has created a new dimension for visual teaching and learning with web-delivered interactive media. The Virtual Labs Project has embraced this technology with instructional design and evaluation methodologies behind the simPHYSIO suite of simulation-based, online interactive teaching modules in physiology for the Stanford students. In addition, simPHYSIO provides the convenience of anytime web-access and a modular structure that allows for personalization and customization of the learning material. This innovative tool provides a solid delivery and pedagogical backbone that can be applied to developing an interactive simulation-based training tool for the use and management of the Picture Archiving and Communication System (PACS) image information system. The disparity in the knowledge between health and IT professionals can be bridged by providing convenient modular teaching tools to fill the gaps in knowledge. An innovative teaching method in the whole PACS is deemed necessary for its successful implementation and operation since it has become widely distributed with many interfaces, components, and customizations. This paper will discuss the techniques for developing an interactive-based teaching tool, a case study of its implementation, and a perspective for applying this approach to an online PACS training tool.

The Relevance of People’s Attitudes Towards Freedom of Expression in a Changing Media Environment

Directory of Open Access Journals (Sweden)

Teresa K. NAAB

2012-01-01

Full Text Available The article outlines arguments for the relevance of people’s attitudes towards freedom of expression: It is a fundamental principle of democracy that if a virtue does not receive support from the population, it will not be anchored in law and its foundation is endangered in the medium term. People’s support for free speech is becoming even more influential because authoritative control of internet communication is faced with difficulties. Furthermore, with the development of social media users gain new opportunities to publicly express their opinions attaching even more importance to normative self-regulation. As a matter of fact, these increased opportunities of self-regulation may either enhance or decrease the exercise of expression rights. Thus, citizen’s endorsement of free expression is a valuable indicator of the status of freedom of expression in a country. To approach to the subject empirically, the paper systematizes findings on people’s attitudes towards free speech: Most people believe in freedom of expression in the abstract. Willingness to apply the right to opposing groups, however, is lower. Perceived threats, confidence in democratic principles, mode of communication, and personality variables influence tolerance of expressions. Finally, a research agenda is put forward to examine appreciation of free expression, its antecedence, and implications.

Global Software Development (GSD) is getting fame in the software industry gradually. However, in GSD, multiple and diverse stakeholders are involved in the development of complex software systems. GSD introduces several challenges, i.e. physical distance, time zone, culture difference, language barriers. As requirements play a significant role in any software development. The greatest challenge in GSD environment is to maintain a consistent view of the system even if the requirements change. But at the same time single change in the requirement might affect several other modules. In GSD different people use terms and have different ways of expressing the concepts for which people at remote sites are unable to get uniformity regarding the semantics of the terms. In a global environment requires effective communication and coordination. However, to overcome inconsistencies and ambiguities among the team members and to make the team members aware of the consistent view, a shared and common understanding is required. In this paper an approach beneficial to software industry has been proposed, focusing on changing requirements in a Global Software Development environment. A case study has been used for the evaluation of the proposed approach. Therefore, Requirements change management process has been improved by applying the approach of the case study. The proposed approach is beneficial to the software development organizations where frequent changes occur. It guided the software industry to provide the common understandings to all the development teams residing in remote locations. (author)

learning and media ecologies with the material, global and ecological challenges that have become a part of the anthropocene. They do so by examining the mediation of a physical, architectural environment, their own departmental environment at Simon Fraser University. De Castell, Droumeva and Jenson uncover a range of practical and theoretical challenges, and explore the implications for both body and mind. Markus Deimann takes the reader back into the history of continental educational theory, to Humboldt’s (and others‘ expansive understanding of Bildung, to suggest a conceptual ecology germane to the manifold possibilities that are now on offer through open education. Deimann sees the «open paradigm» as changing education utterly – and for the better. It will do so, Deimann predicts, by «unbundling» resource and service provision, and assessment and accreditation functions that have for too long been monopolized by the educational monoliths known as «universities». Theo Hug’s contribution, «Media Form School – A Plea for Expanded Action Orientations and Reflective Perspectives» similarly looks to the past to envision possibilities for the future. Hug’s concern is with the narrow confines in which media are conceptualized and operationalized in many K-12 educational ecologies, and in the corresponding policy and curricular documents that further constrain and direct this action. Hug suggests looking to the recent past, the 1970s and 1960s, in which alternatives were envisioned not only by figures like McLuhan and Illich, but also intimated in the works of Austrian poets and artists. Norm Friesen provides the third «rearview mirror» perspective in his examination of the lecture as a trans-medial pedagogical form. From the late medieval university through to today’s IGNITE and TED talks, the lecture has accommodated and reflected a wide range of media ecologies, technical conditions and epistemological patterns.

Mainstream Media and Social Media Reactions to the Discovery of Extraterrestrial Life

Science.gov (United States)

Jones, Morris

The rise of online social media (such as Facebook and Twitter) has overturned traditional top-down and stovepiped channels for mass communications. As social media have risen, traditional media sources have been steadily crippled by economic problems, resulting in a loss of capabilities and credibility. Information can propagate rapidly without the inclusion of traditional editorial checks and controls. Mass communications strategies for any type of major announcement must account for this new media landscape. Scientists announcing the discovery of extraterrestrial life will trigger a multifaceted and unpredictable percolation of the story through the public sphere. They will also potentially struggle with misinformation, rumours and hoaxes. The interplay of official announcements with the discussions of an extraterrestrial discovery on social media has parallels with traditional theories of mass communications. A wide spectrum of different messages is likely to be received by different segments of the community, based on their usage patterns of various media and online communications. The presentation and interpretation of a discovery will be hotly debated and contested within online media environments. In extreme cases, this could lead to "editorial wars" on collaborative media projects as well as cyber-attacks on certain online services and individuals. It is unlikely that a clear and coherent message can be propagated to a near-universal level. This has the potential to contribute to inappropriate reactions in some sectors of the community. Preventing unnecessary panic will be a priority. In turn, the monitoring of online and social media will provide a useful tool for assessing public reactions to a discovery of extraterrestrial life. This will help to calibrate public communications strategies following in the wake of an initial announcement.

Although a growing number of psychosocial health promotion interventions use the critical analysis of media to facilitate behavior change, no specific guidelines exist to assist researchers and practitioners in the selection and evaluation of culturally relevant media stimuli for intervention development. Mobilizing Our Voices for Empowerment is a critical consciousness-based health enhancement intervention for HIV-positive Black young gay/bisexual men that employs the critical analysis of popular media. In the process of developing and testing this intervention, feedback on media stimuli was collected from youth advisory board members (n = 8), focus group participants (n = 19), intervention participants (n = 40), and intervention facilitators (n = 6). A thematic analysis of qualitative data resulted in the identification of four key attributes of media stimuli and participants' responses to media stimuli that are important to consider when selecting and evaluating media stimuli for use in behavioral health interventions employing the critical analysis of media: comprehension, relevance, emotionality, and action. These four attributes are defined and presented as a framework for evaluating media, and adaptable tools are provided based on this framework to guide researchers and practitioners in the selection and evaluation of media for similar interventions.

2013-10-01

Norway has one of the most comprehensive infrastructures for tobacco control in the world and has launched several media campaigns recent years. Can yet another anti-smoking campaign, using fear appeal messages, have an immediate impact on smoking behavior, motivation to quit and health beliefs? A sample of smokers (N = 2543) completed a survey before and after a 7-week national media campaign. Individual exposure to campaign (unaided recall) was used as predictor of change. We observed no statistically significant effect on smoking status but tendencies were in the expected direction for daily smokers (P = 0.09). There were no effects on number of cigarettes per day, likelihood to quit or reduce smoking. Small but statistically significant effects were found on motivation to quit (P < 0.01, ηp(2) = 0.004) and perceived seriousness of health hazards (P < 0.05, ηp(2) = 0.002). In addition, there was an increase in interpersonal discussions about health and smoking for those exposed to the campaign (P < 0.01, ηp(2) = 0.008). We conclude that there are very small effects of a relatively short and intense mass media campaign on a population of smokers already exposed to one of the most comprehensive tobacco control programs in the world.

Full Text Available This podcast is a recording of a research seminar that took place on December 3, 2015, at the University of Westminster's Communication and Media Research Institute (CAMRI. In this contribution, David Gauntlett discusses his new book, Making Media Studies, and other new work. In Making Media Studies (Peter Lang, 2015, Gauntlett proposes a vision of media studies based around doing and making – not about the acquisition of skills, as such, but an experience of building knowledge and understanding through creative hands-on engagement with all kinds of media. Gauntlett suggests that media studies scholars have failed to recognise the significance of everyday creativity – the vital drive of people to make, exchange, and learn together, supported by online networks. He argues that we should think about media in terms of conversations, inspirations, and making things happen. Media studies can be about genuine social change, he suggests, if we recognise the significance of everyday creativity, work to transform our tools, and learn to use them wisely.

The American Academy of Pediatrics recognizes exposure to violence in media, including television, movies, music, and video games, as a significant risk to the health of children and adolescents. Extensive research evidence indicates that media violence can contribute to aggressive behavior, desensitization to violence, nightmares, and fear of being harmed. Pediatricians should assess their patients' level of media exposure and intervene on media-related health risks. Pediatricians and other child health care providers can advocate for a safer media environment for children by encouraging media literacy, more thoughtful and proactive use of media by children and their parents, more responsible portrayal of violence by media producers, and more useful and effective media ratings.

Pediatricians and other child health care providers can advocate for a safer media environment for children by encouraging media literacy, more thoughtful and proactive use of media by children and their parents, more responsible portrayal of violence by media producers, and more useful and effective media ratings. Office counseling has been shown to be effective.

Social mobilization programs for immunization have been used by African leaders, however, coverage from 20% to 70% in capitals like Mogadishu, Maputo, and Dakar were the result of short campaigns rather than the consequence of knowledge, attitudes, and practices (KAP) improvement. One-party states relied on their network of cadres issuing decrees from the top down to enforce completion of these immunization campaigns. Sometimes resistance developed against these programs, as the military mobilized people (e.g., Somalia). These efforts became rather superficial once the temporary pressure evaporated. In Mogadishu coverage increased from 22% to 70% in 1985, and within a year it dropped back to 8% above the original level. Nigeria, Senegal, and Togo where they used regular mini campaigns had better results. Research data from Botswana, Kenya, Lesotho, Malawi, Mozambique, and Zambia were analyzed. In 1983 in Kenya 73% of health workers never advised their clients, and 82% were incompetent to do so. Data also showed that clinics provided the bulk of information to women aged 15-45 in lower income groups, but they rarely consulted village health workers. Radio and TV programs were not reaching people because radio ownership was not universal (47% in Zambia and 30% in Zimbabwe), and batteries were often not available. In addition, most people turned to the radio for entertainment. In 1989, vaccination coverage was 19% in Luanda, Angola, but only 5% of 232 respondents to an evaluation could name the immunizable diseases. An identical percentage was familiar with these diseases in a Zambian study in 1986. Media experts proposed dramas to raise interest, but innovative mass media programs of dissemination of the message advocated in the 1960s did not prove effective to bring about KAP changes. Training of health and paramedical personnel by mass organizations as initiated in Ethiopia may prove to be worthwhile.

Nagano, Katsumasa; Tobari, Kousuke; Futamoto, Masaaki

2011-01-01

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.

Full Text Available In Japan, the interwoven systems of communication, transport, and information and the commercially-industrially-culturally compressed spaces of the metropoles, like Tokyo, have created super-density as new cultural form of the present. In this respect, the installation works by Seiko Mikami respond to quotidian experience with high density and lack of individual space. In her interactive installations, we are targeted by programmed multisensors and robotic devices, which invite us to engage in close encounter with the measuring and moving tools of the installation. In this human-machine-interrelationship, which is set out for multiple participants, we will also achieve a sense of each other via technology. The technological environment becomes a perceptual space, which instigates awareness and self-awareness of our own. Yvonne Spielmann (Ph.D., Dr. habil. is presently Research Professor and Chair of New Media at The University of the West of Scotland. Her work focuses on interrelationships between media and culture, technology, art, science and communication, and in particular on Western/European and non-Western/South-East Asian interaction.

In this study, the intracellular proteome of Escherichia coli O157:H7 strain EDL933 was analyzed by two-dimensional gel electrophoresis and matrix-assisted laser desorption ionization-time-of-flight (MALDI-TOF) spectrometry after growth in simulated ileal environment media (SIEM) and simulated colonic environment media (SCEM) under aerobic and microaerobic conditions. Differentially expressed intracellular proteins were identified and allocated to functional protein groups. Moreover, metabolic fluxes were analyzed by isotopologue profiling with [U-(13)C(6)]glucose as a tracer. The results of this study show that EDL933 responds with differential expression of a complex network of proteins and metabolic pathways, reflecting the high metabolic adaptability of the strain. Growth in SIEM and SCEM is obviously facilitated by the upregulation of nucleotide biosynthesis pathway proteins and could be impaired by exposition to 50 µM 6-mercaptopurine under aerobic conditions. Notably, various stress and virulence factors, including Shiga toxin, were expressed without having contact with a human host.

Armenian media coverage of science topics

Science.gov (United States)

Mkhitaryan, Marie

2016-12-01

The article discusses features and issues of Armenian media coverage on scientific topics and provides recommendations on how to promote scientific topics in media. The media is more interested in social or public reaction rather than in scientific information itself. Medical science has a large share of the global media coverage. It is followed by articles about environment, space, technology, physics and other areas. Armenian media mainly tends to focus on a scientific topic if at first sight it contains something revolutionary. Media primarily reviews whether that scientific study can affect the Armenian economy and only then decides to refer to it. Unfortunately, nowadays the perception of science is a little distorted in media. We can often see headlines of news where is mentioned that the scientist has made "an invention". Nowadays it is hard to see the border between a scientist and an inventor. In fact, the technological term "invention" attracts the media by making illusionary sensation and ensuring large audience. The report also addresses the "Gitamard" ("A science-man") special project started in 2016 in Mediamax that tells about scientists and their motivations.

‘Daring Leaps’ Construction of Meaning and Individual Agency in Career Change Narratives in the Media

Directory of Open Access Journals (Sweden)

Kirsi LaPointe

2014-05-01

Full Text Available The role of individual agency in crafting meaningful work has attracted increasing interest in recent studies of careers and working life. The purpose of this paper is to make visible the role of the media in reproducing and shaping understandings of careers and agency. By analyzing narratives of career change in the Finnish media, we identify three types of narrative and show how they construct meaningful careers by juxtaposing the past and present work in terms of setting, status, meaning, pace, and workload. Overall, these narratives depict a shift from traditional careers toward work that is concrete, meaningful, of lower status, and less hectic. Moreover, the narratives represent career changers as self-reliant heroes taking “daring leaps.” Hence, we argue that the media reproduces individualistic assumptions of careers and reinforces the dominant, neoliberal ideal of self-responsible, autonomous subjects. We conclude by calling for alternative narratives that recognize the need for more meaningful careers but help strengthen agency in a less individualistic fashion.

The failure to integrate environmental and organizational interventions may help explain the lack of success of many change efforts. The high rate of failure for change efforts (50% to 90% failure rates) has been noted by many writers. While specific causes of failure are diverse, a common theme has been failure to consider the organization as a system. That is, either significant aspects of the organization were ignored during the intervention or potential impacts of changes on the elements were overlooked or underestimated. Our own training, technical literature, and professional culture lead us to limited understandings of complex organizations. Change agents must consider all relevant components of organizational performance if interventions are to be meaningful and successful. This study demonstrated the value of an integrated organizational intervention involving redesign of the physical environment, introduction of a new information system, work process improvement, and extended organizational development intervention. The outcomes were extremely positive. The cost of improvement efforts was found to be recaptured within a short time, easily justifying the expenditures. One conclusion from the study is that integrated interventions are very powerful. Integrating improvement of the physical environment with organizational development and technological innovation greatly enhances the likelihood of achieving a successful intervention.

Origins of media literacy and its theories funded on Len Masterman

Marina Tornero

2017-11-01

Full Text Available Media literacy is the subject that teaches critical thinking about media. Despite its importance in a society dominated by television, newspapers and especially the Internet, it is still a big unknown in the educational environment. This article shows its evolution from the concept of Semiotics by Roland Barthes and Umberto Eco to the analysis of visual culture as a way of understanding the search for information and entertainment among young people and adults.  One of the leading experts in media literacy is Len Masterman, whose publications revolutionized the use of media in education not as a tool for learning, but the object to study in a critical way. His educational perspective is focused on making young people participate in the classroom, actively questioning what they see daily in the media environment and facilitating its critical development.

Environmental Progression: The Psychological Justification for Reframing Climate Change and Global Warming

Science.gov (United States)

Veldey, S. H.

2016-12-01

On-going research in climate science communication through environmental media has uncovered critical barriers to reducing denial and increasing agency in addressing the threat of climate change. Similar to framing of our changing environment as "global warming", the term "climate change" also fails to properly frame the most critical challenge our species has faced. In a set of preliminary studies, significant changes in climate crisis denial, both positive and negative, have resulted from different media messaging. Continuation of this research utilizes social judgement theory (SJT) to classify a broader spectrum of effective avenues for environmental communication. The specificity of the terms global warming and climate change limit inclusion of issues critical to understanding their impacts. Now that the masses know what climate change is, it's time to teach them what it means.

The Duality of Social Media in Tourism

Full Text Available Today’s technologies offer many opportunities for communication and for developing the social, political and economic environments. Social media is one of the channels highly used for personal and business communication in our informational society. However, the various facets of the social media may not be employed in the same manner for the needs of the individual as they are for the needs of the businesses aiming to develop in the tourism sector. This paper aims to identify which of the social media platforms are appropriate for being used for personal purposes and which are more suitable for developing a business in tourism, amongst the users of social media. The paper bases its conclusions on a survey applied on a sample of Romanian young people (18 – 35 years old involved in tourism business environment, as according to research in the field such as Lenhart, Purcell, Smith and Zichur (2010 and Cabral (2011 this is the most active segment in social media. The findings presented in the paper result from the analysis of the survey responses and they indicate that all four types of social media platforms taken into account: social networks, blogs, micro-blogs and video file sharing platforms are used for both personal and business purposes. However, inside each of the four types of platforms surveyed there were noticed certain preferences, from the point of view of users’ interests in communication: personal purpose communication or business in tourism purpose communication.

Burnette, C Blair; Kwitowski, Melissa A; Mazzeo, Suzanne E

2017-12-01

Social media appear to contribute to body dissatisfaction in adolescents, although few empirical studies exist. This study used six focus groups (total N=38) to explore relations between social media use and body image in early adolescent girls (ages 12-14). Thematic analysis identified patterns in the data. In this sample, social media use was high. Girls endorsed some appearance concerns and social comparison, particularly with peers. However, they displayed high media literacy, appreciation of differences, and confidence, strategies that appeared helpful in mitigating the potential negative association between social media exposure and body image. Girls reported these characteristics were nurtured by positive parental influence and a supportive school environment. Results support an ecological approach to the prevention of body dissatisfaction. Although peer influence strengthens throughout adolescence, current findings suggest that parents and the school environment are associated with girls' attitudes and behaviors regarding social media and body image.
