Effects of the Mass Media of Communication.  

ERIC Educational Resources Information Center

The mass media are considered to be television, radio, movies, and newspapers. They may generate changes in cognition and comprehension. They do effect emotional arousal, sex and behavior identification, and changes in allocation of time, consumer purchase, and voting behavior. The only data which show a clear relationship between the mass media

Effective Use of Social Media in Communicating Climate Science  

NASA Astrophysics Data System (ADS)

The internet and social media have been a critical vector for misinformation on climate change. Scientists have not always been proactive or effective in utilizing the medium to bring attention to the best science, to correct misinformation and overcome urban myths. Similarly, mainstream journalists have been handicapped in dealing with the wide open nature of the medium, and often muted by editorial concerns or budget restrictions. Independent communicators who are highly motivated can make inroads in this area by using the internet's immediacy and connectivity to consistently connect viewers and readers to reliable information. Over the last 4 years, I have developed a series of you tube videos, made deliberately provocative to engage the internet's confrontational culture, but carefully crafted to bring the best science into the freewheeling community. In doing so, I have won the confidence of leading climate scientists, and in some cases assisted them in clarifying their message. This presentation will share simple tips, useful practices, and effective strategies for making complex material more clear and user friendly, and help scientists better convey the stories hidden in their data.

Effective media communication of disasters: Pressing problems and recommendations  

PubMed Central

Background Public health officials and journalists play a crucial role in disseminating information regarding natural disasters, terrorism and other human-initiated disasters. However, research suggests that journalists are unprepared to cover terrorism and many types of natural disasters, in part because of lack sufficient expertise in science and medicine and training. The objective of this research was to identify solutions to problems facing journalists and public health public information officer (PIOs) of communicating with the public during natural and human-initiated disasters. Methods To assist in identifying the most pressing problems regarding media response to health-related risks such as terrorism and large-scale natural disasters, 26 expert advisors were convened, including leaders representing journalists and public information officers, state health officials, experts in terrorism and emergency preparedness, and experts in health, risk, and science communication. The advisory group participated in pre-arranged interviews and were asked to identify and review bioterrorism educational resources provided to journalist. All advisory group members were then invited to attend a day long meeting January 29, 2004 to review the findings and reach consensus. Results The most pressing problems were found to be a lack of coordination between PIO's and journalists, lack of resources for appropriately evaluating information and disseminating it efficiently, and a difference in perception of PIO's and journalist towards each others role during emergency situations. The advisory board developed a list of 15 recommendations that may enhance communication plans betweens PIO's, journalist and the public. The solutions were meant to be feasible in terms of costs and practical in terms of the professional and organizational realities in which journalists and PIO's work. Conclusion It is clear that PIO's and journalists play crucial roles in shaping public response to terrorism and other disasters. The findings from this formative research suggest that perspectives and organizational processes often limit effective communication between these groups; though practical solutions such as participation of journalists in drills, scenario exercises, sharing of informational resources, and raising awareness at professional trade meetings may enhance the timely dissemination of accurate and appropriate information.

Scientific Story Telling & Social Media The role of social media in effectively communicating science  

NASA Astrophysics Data System (ADS)

Scientific discourse generally takes place in appropriate journals, using the language and conventions of science. That's fine, as long as the discourse remains in scientific circles. It is only outside those circles that the rules and techniques of engaging social media tools gain importance. A young generation of scientists are eager to share their experiences by using social media, but is this effective? And how can we better integrate all outreach & media channels to engage general audiences? How can Facebook, Twitter, Skype and YouTube be used as synergy tools in scientific story telling? Case: during IODP Expedtion 342 (June-July 2012) onboard the scientific drillship JOIDES Resolution an onboard educator and videographer worked non-stop fort two months on an integrated outreach plan that tried and tested the limits of all social media tools available to interact with an international public while at sea. The results are spectacular!

Effects of media messages on parent-child sexual communication.  

PubMed

Parent-child communication about sex is an important reproductive health outcome. Consistent, positive perceptions of communication by parents and children can promote behavioral outcomes such as delaying sexual debut and increasing contraceptive use. The authors investigated whether exposure to messages from the Parents Speak Up National Campaign (PSUNC), a social marketing campaign to promote increased parent-child sexual communication, led to increased children's self-reports of communication. Also, the authors examined whether PSUNC message exposure increased agreement about communication between parents and their children. In a randomized experimental design, the authors surveyed children of parents exposed and not exposed to PSUNC messages. Parents and children completed online instruments asking matched questions about sexual attitudes, beliefs, and communication. The authors matched 394 parents and children for analysis. They used ordinal logistic regression modeling and kappa statistics. Children of parents exposed to PSUNC messages were more likely to (a) report sexual communication than were those not exposed and (b) agree with their parents about extent and content. Parent-child pairs of the same gender, younger pairs, and non-White pairs were more likely to agree. Overall, PSUNC message exposure appears to have promoted more extensive sexual communication. Future research should examine behavioral mechanisms and message receptivity among subgroups of parents and children. PMID:22339275

The relationship between adolescents' news media use and civic engagement: the indirect effect of interpersonal communication with parents.  

PubMed

Using data from the 4-H Study of Positive Youth Development, a longitudinal study involving U.S. adolescents, multi-group structural equation modeling (SEM) was used to evaluate whether news media use is predictive of a set of civic indicators (civic duty, civic efficacy, neighborhood social connection, and civic participation) for youth in Grades 8, 9, and 10, via an indirect effect of interpersonal communication about politics with parents. The proposed model had a good fit within each grade. News media use was predictive of interpersonal communication with parents and in turn, interpersonal communication was predictive of civic duty, civic efficacy, neighborhood social connection, and civic participation. The cross-group comparison of the structural model suggests that the predictive qualities of news media use and interpersonal communication are comparable across grades. The role of media use and interpersonal communication in fostering civic development and socialization as well as implications for future research are discussed. PMID:22118509

Interpersonal communication as an indirect pathway for the effect of antismoking media content on smoking cessation.  

PubMed

In the context of health campaigns, interpersonal communication can serve at least 2 functions: (a) to stimulate change through social interaction and (b) in a secondary diffusion process, to further disseminate message content. In a 3-wave prospective study of 1,079 smokers, the authors demonstrate that mass media messages (antismoking campaigns and news coverage relevant to smoking cessation) have an indirect effect on smoking cessation intention and behavior via interpersonal communication. Exposure to campaigns and news coverage prompts discussion about the campaigns, and, in turn, about smoking cessation. Interpersonal communication regarding smoking cessation then influences intention to quit smoking and attempts to quit smoking. The study finds evidence not only for the social interaction function of interpersonal communication, but also for the secondary diffusion function. A substantial number of smokers who are not directly exposed to the antismoking campaigns are nevertheless indirectly exposed via communication with people who have seen these campaigns. These results imply that encouragement of interpersonal communication can be an important campaign objective. PMID:21337250

[Effect of mass communication media in food purchasing at the family level].  

PubMed

The main purpose of this study was to determine the effect of mass media advertisement of food products (TV, radio and the press), particularly in pre-school and school-age children, as well as the concomitant impact these age groups have on the family food buying patterns. To test the hypothesis that the impact of mass media advertising on foods varied in the different socioeconomic levels of a community, a stratified sample of all children below 13 years of age, who attended the Francisco Fajardo school in the central coast of Venezuela, was drawn. Mass media contact, food and nutrition knowledge and other socioeconomic characteristics were related to the family's food-buying patterns. More specifically, the age, working status and educational level of the mother in regard to beliefs concerning the nutritional value of advertized food products, were related. A semi-structured questionnaire was designed, tested and applied to the housewife or whoever performed this role within the family. Findings revealed that families of low socioeconomic status are prone to be most influenced by mass media food product advertising. This is reflected not only in food purchasing practices but also in food consumption patterns at the family level. Chocolate drinks, cereals, jello, sausages, and ice cream are the most popular products among pre-school and school-aged children, without social class distinction. Furthermore, results revealed that the degree of exposure to mass communication media--television, radio and newspapers--is a determining factor in children's food preferences at all socioeconomic levels, and that television is the media exerting the greatest influence.

Effects of communication media choice on the quality and efficacy of emergency calls assisted by a mobile nursing protocol tool.  

PubMed

The transition from paper to electronic-based records in the healthcare industry has posed several challenges to conventional medical practices. The introduction of technology in day-to-day medical and nursing practices deserves careful consideration. In this work, we report the results of a controlled experiment to compare nurses' consultation in emergency calls in six different conditions. We studied the effect that the type of communication media (face-to-face, telephone, videoconference) and type of nursing protocol media (paper-based, electronic-based) can have on consultation time, mistakes made, pauses during consultation, eye contact, and efficacy of the consultation. We found that the type of communication media has an effect on consultation time; on average, fewer mistakes were made during telephone-based consultations; for eye contact, there were significantly fewer eye contacts during face-to-face than during videoconference consultations; finally, the type of communication media or protocol media did not have any effect in the efficacy of the consultation.

Optical wireless communication through random media  

NASA Astrophysics Data System (ADS)

The growing need for high data-rate communication both through the atmosphere and the ocean (sub-sea) has stimulated considerable interest in optical wireless communication (OWC) technologies. The main advantages of OWC as compared with RF communication in the atmosphere and with acoustic communication in sub-sea applications are a) high achievable data-rate, b) small size of equipment and c) low power-consumption. On the other hand the characteristics of the communication channel in both scenarios are stochastic with high values of variance, which severely degrades OWC communication system performance. In this paper we present a tutorial discussing the effects of random media on OWC and expand on two examples: Monte-Carlo simulation for sub-sea communication and mathematical synthesis using Meijer G-function for OWC through atmospheric turbulence. These two examples demonstrate that it is possible to gain significant insights on the effects of the random channel on system performance. The results of the different analysis methods could also indicate solutions for the improvement of performance using adaptive solutions or for extending the communication range by applying a multi-hop concept. We summarize the paper with a brief review of two emerging research fields that could, surprisingly, benefit from the characteristics of light propagation through random media and its effect on the communication system performance. The first research field is trans-cutaneous OWC and the second is an unguided optical communication bus for next-generation computers.

One thing is clear: the range of social media platforms that scientists are using is relatively vast and dependent on discipline and sentiment. While the future of social media is unknown, a combination of educated speculation and persuasive fact points to the industry's continual growth and influence. Thus, is that not only are scientists utilizing social media to communicate their research, they must. The ability to communicate to the masses via social media is critical to the distribution of scientific information amongst professionals in the field and to the general population. PMID:22085450

Transformation of Traditional Marketing Communications in to Paradigms of Social Media Networking  

E-print Network

Effective Communication for marketing is a vital field in business organizations, which is used to convey the details about their products and services to the market segments and subsequently to build long lasting customer relationships. This paper focuses on an emerging component of the integrated marketing communication, ie. social media networking, as it is increasingly becoming the trend. In 21st century, the marketing communication platforms show a tendency to shift towards innovative technology bound people networking which is becoming an acceptable domain of interaction. Though the traditional channels like TV, print media etc. are still active and prominent in marketing communication, the presences of the Internet and more specifically the Social Media Networking, has started influencing the way individuals and business enterprises communicate. It has become evident that more individuals and business enterprises are engaging the social media networking sites either to accelerate the sales of their pro...

Highly survivable communications: Complementary media packet switched networks  

NASA Astrophysics Data System (ADS)

The requirement for highly survivable communications (HSC) for essential command functions in military operations does not need any justification. The ability to communicate under extreme jamming levels and adverse propagation conditions, including high altitude nuclear events, is a very important requirement. There are also many natural disaster related requirements that also need such highly survivable communications. The prevalent and in a sense classical, approach to provide highly assured connectivity can be summarized as follows: Take a particular propagation medium and try to obtain the ultimate performance from it. There are many examples of this philosophy some successful, most not. Our approach, on the other hand, is to use complementary multi-media or mixed-media where communication links utilizing essentially commercial-off-the-shelf (COTS) equipment are integrated using packet radio (PR) techniques. There is also, in our view, an even more fundamental, recently discovered consideration why the expectation of continuous incremental refinement of a system using a given single media may be be achievable. This is derived from the theory of 'deterministic uncertainty' or more popularly known as 'theory of CHAOS', systems whose state space behavior has fractal characteristics. We will elaborate on this novel argument. Complementary multi-media approach has been the focus for all HSC communications activities at STC since 1982. The original STC studies and prototypes were in response to requirements of broadcasting (i.e., one-way transmission) information. A high frequency (HF)/meteorburst (MB) system was developed/prototyped/tested demonstrating the cost effectiveness of the approach. These results are reviewed. More recently, in 1992 STC has completed the development/test of an Open Systems Interconnection (OSI) HF packet radio protocol as no such open or non-proprietary protocol exists. This protocol has been fully tested, documented and made available to all NATO nations/industries. These extensive results show that significant improvements in throughput of up to many times are obtained. A similar development for an OSI MB protocol has also been completed and combined with the HF protocol to obtain an OSI HF/MB link layer protocol with unique properties for HSC networks. Description of these protocols and the relevant results are presented. media diversity.

Using social media to communicate during crises: an analytic methodology  

NASA Astrophysics Data System (ADS)

The Emerging Media Integration Team at the Department of the Navy Office of Information (CHINFO) has recently put together a Navy Command Social Media Handbook designed to provide information needed to safely and effectively use social media. While not intended to be a comprehensive guide on command use of social media or to take the place of official policy, the Handbook provides a useful guide for navigating a dynamic communications environment. Social media are changing the way information is diffused and decisions are made, especially for Humanitarian Assistance missions when there is increased emphasis on Navy commands to share critical information with other Navy command sites, government, and official NGO (nongovernmental organization) sites like the American Red Cross. In order to effectively use social media to support such missions, the Handbook suggests creating a centralized location to funnel information. This suggests that as the community of interest (COI) grows during a crisis, it will be important to ensure that information is shared with appropriate organizations for different aspects of the mission such as evacuation procedures, hospital sites, location of seaports and airports, and other topics relevant to the mission. For example, in the first 14 days of the U.S. Southern Command's Haiti HA/DR (Humanitarian Assistance/Disaster Relief) mission, the COI grew to over 1,900 users. In addition, operational conditions vary considerably among incidents, and coordination between different groups is often set up in an ad hoc manner. What is needed is a methodology that will help to find appropriate people with whom to share information for particular aspects of a mission during a wide range of events related to the mission. CNA has developed such a methodology and we would like to test it in a small scale lab experiment.

Gap between science and media revisited: Scientists as public communicators  

PubMed Central

The present article presents an up-to-date account of the current media relations of scientists, based on a comprehensive analysis of relevant surveys. The evidence suggests that most scientists consider visibility in the media important and responding to journalists a professional duty—an attitude that is reinforced by universities and other science organizations. Scientific communities continue to regulate media contacts with their members by certain norms that compete with the motivating and regulating influences of public information departments. Most scientists assume a two-arena model with a gap between the arenas of internal scientific and public communication. They want to meet the public in the public arena, not in the arena of internal scientific communication. Despite obvious changes in science and in the media system, the orientations of scientists toward the media, as well as the patterns of interaction with journalists, have their roots in the early 1980s. Although there is more influence on public communication from the science organizations and more emphasis on strategic considerations today, the available data do not indicate abrupt changes in communication practices or in the relevant beliefs and attitudes of scientists in the past 30 y. Changes in the science–media interface may be expected from the ongoing structural transformation of the public communication system. However, as yet, there is little evidence of an erosion of the dominant orientation toward the public and public communication within the younger generation of scientists. PMID:23940312

[Social media and health communication: do we need rules?].  

PubMed

Social media, online social networks and apps for smartphones and tablets are changing the way to communicate health and health issues to consumers and health professionals. Google, Facebook, Apple, and other companies have launched tools to make easier the doctor-patient communication, to group patients with similar diseases allowing them to share stories, experiences, and opinions, and to remotely track and monitor users health and wellbeing. However several concerns about patients' and consumers' privacy remain. Doctor-patient communication through e-mail and social media also introduces other ethical and privacy issues that were addressed only by few medical societies with appropriate guidelines and policies. In addition, pharmaceutical companies have started to use social media channels to communicate with doctors, patients and consumers. This type of communication has been only partially regulated by the Food and Drug Administration with the recently published guidelines for industries. Similar concerns exist for health and medical applications for smartphones and tablets for which only few agencies (including Food and Drug Administration) are requiring a formal (even if restricted in typology) validation. It's time for Europe and Italy to adopt appropriate guidelines for the use of the new media in health communication. PMID:25621774

The MAVEN mission to Mars: Communicating science through social media  

NASA Astrophysics Data System (ADS)

While science literacy rates in the U.S. have recently increased, overall levels remain remarkably low.There are opportunities for the public to learn about science and to engage directly with real-life practitioners. It is the responsibility of science education and communications professionals to provide these opportunities and to assess the effectiveness of each platform. At the University of Colorado's Laboratory for Atmospheric and Space Physics (LASP), we utilize a diverse, well-tested approach to introduce science to the public and to give scientists access to the broadest possible audience. This poster will focus on NASA's MAVEN mission to Mars and the social media outlets we have incorporated into our Education and Public Outreach (EPO) program in order to introduce rather complex science concepts to the public. We'll examine several evaluation tools that are used to provide ongoing, immediate feedback regarding our strategies and to guide long-term efforts. MAVEN educators and scientists are capitalizing on the recent excitement surrounding Mars science and the public's fascination with the search for life to bring the science of the mission directly to a variety of audiences. Our EPO professionals are using cross-platform, transportable content to maximize exposure and create pathways for two-way interactions between our audience and mission experts. We are using social media tools to build a community that will join us in the MAVEN journey and its important scientific discoveries.

Mass media entertainment for AIDS communication in Zaire.  

PubMed

Health communicators use entertainment and mass media to prevent HIV transmission. Population Services International operates an AIDS Mass Media Project as an adjunct to its Condom Social Marketing Project. It collaborates with the Government of Zaire's National AIDS Program. Its 1st target is urban youth because most AIDS cases in Zaire were infected as teenagers, urban youth have access to television (TV), and they take part in high risk sexual behavior. The project uses various AIDS songs to reach this group. A 6-month posttest shows that the 1st song was so effective that 65% heard it and that 93% of them recalled the major AIDS messages and 85% said that they changed their behavior. The project distributes a video of the 1990 World AIDS Day concert. Research in Zaire and other African countries shows that the threat AIDS poses to children's health strongly motivates parents' behavior. Thus the 2nd target is the 20-30 year old group--young and prospective parents. The project boasts a 4-part TV series about a groom who does not reveal his AIDS status to his young bride until after their wedding night. 2 scenes stress the benefits of condoms. After its 1st airing, 66% of the 20-30 year old group in Kinshasa watched all 4 parts of the series. Of these, about 75% said they would change their behavior. Most people in Zaire change behavior by using condoms. Indeed, during the mass media campaign, condom sales grew 1000% which saved almost 7200 lives. The project also features comic strips informing working men and women and teenagers about AIDS and distributes an inexpensive notebook listening AIDS facts and myths for school children. The project uses regional radio stations to broadcast 28 AIDS feature programs, 22 radio spots, 8 AIDS radio dramas, and 2 songs to high priority rural areas. These AIDS radio efforts have indeed influenced AIDS knowledge and attitudes. PMID:12285440

Social Media Use in the United States: Implications for Health Communication  

PubMed Central

Background Given the rapid changes in the communication landscape brought about by participative Internet use and social media, it is important to develop a better understanding of these technologies and their impact on health communication. The first step in this effort is to identify the characteristics of current social media users. Up-to-date reporting of current social media use will help monitor the growth of social media and inform health promotion/communication efforts aiming to effectively utilize social media. Objective The purpose of the study is to identify the sociodemographic and health-related factors associated with current adult social media users in the United States. Methods Data came from the 2007 iteration of the Health Information National Trends Study (HINTS, N = 7674). HINTS is a nationally representative cross-sectional survey on health-related communication trends and practices. Survey respondents who reported having accessed the Internet (N = 5078) were asked whether, over the past year, they had (1) participated in an online support group, (2) written in a blog, (3) visited a social networking site. Bivariate and multivariate logistic regression analyses were conducted to identify predictors of each type of social media use. Results Approximately 69% of US adults reported having access to the Internet in 2007. Among Internet users, 5% participated in an online support group, 7% reported blogging, and 23% used a social networking site. Multivariate analysis found that younger age was the only significant predictor of blogging and social networking site participation; a statistically significant linear relationship was observed, with younger categories reporting more frequent use. Younger age, poorer subjective health, and a personal cancer experience predicted support group participation. In general, social media are penetrating the US population independent of education, race/ethnicity, or health care access. Conclusions Recent growth of social media is not uniformly distributed across age groups; therefore, health communication programs utilizing social media must first consider the age of the targeted population to help ensure that messages reach the intended audience. While racial/ethnic and health status–related disparities exist in Internet access, among those with Internet access, these characteristics do not affect social media use. This finding suggests that the new technologies, represented by social media, may be changing the communication pattern throughout the United States. PMID:19945947

Impediments to media communication of social change in family planning and reproductive health: experiences from East Africa.  

PubMed

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. PMID:24069769

Interactive real-time media streaming with reliable communication  

NASA Astrophysics Data System (ADS)

Streaming media is a recent technique for delivering multimedia information from a source provider to an end- user over the Internet. The major advantage of this technique is that the media player can start playing a multimedia file even before the entire file is transmitted. Most streaming media applications are currently implemented based on the client-server architecture, where a server system hosts the media file and a client system connects to this server system to download the file. Although the client-server architecture is successful in many situations, it may not be ideal to rely on such a system to provide the streaming service as users may be required to register an account using personal information in order to use the service. This is troublesome if a user wishes to watch a movie simultaneously while interacting with a friend in another part of the world over the Internet. In this paper, we describe a new real-time media streaming application implemented on a peer-to-peer (P2P) architecture in order to overcome these challenges within a mobile environment. When using the peer-to-peer architecture, streaming media is shared directly between end-users, called peers, with minimal or no reliance on a dedicated server. Based on the proposed software p?v?a (pronounced [revma]), named for the Greek word meaning stream, we can host a media file on any computer and directly stream it to a connected partner. To accomplish this, p?v?a utilizes the Microsoft .NET Framework and Windows Presentation Framework, which are widely available on various types of windows-compatible personal computers and mobile devices. With specially designed multi-threaded algorithms, the application can stream HD video at speeds upwards of 20 Mbps using the User Datagram Protocol (UDP). Streaming and playback are handled using synchronized threads that communicate with one another once a connection is established. Alteration of playback, such as pausing playback or tracking to a different spot in the media file, will be reflected in all media streams. These techniques are designed to allow users at different locations to simultaneously view a full length HD video and interactively control the media streaming session. To create a sustainable media stream with high quality, our system supports UDP packet loss recovery at high transmission speed using custom File- Buffers. Traditional real-time streaming protocols such as Real-time Transport Protocol/RTP Control Protocol (RTP/RTCP) provide no such error recovery mechanism. Finally, the system also features an Instant Messenger that allows users to perform social interactions with one another while they enjoy a media file. The ultimate goal of the application is to offer users a hassle free way to watch a media file over long distances without having to upload any personal information into a third party database. Moreover, the users can communicate with each other and stream media directly from one mobile device to another while maintaining an independence from traditional sign up required by most streaming services.

Effect of electronic media on children.  

PubMed

Radio, television (TV), movies, video games, cell phones, and computer networks have assumed central roles in our children's daily lives. The media has demonstrated potentially profound effects, both positive and negative, on children's cognitive, social, and behavioral development. Considering the increasing exposure of children to newer forms of media, we decided to review the current literature on the effects of media on child health both in the Western countries and India. It is widely accepted that media has profound influence on child health, including violence, obesity, tobacco and alcohol use, and risky sexual behaviors. Simultaneously, media may have some positive effects on child health. We need to find ways to optimize the role of media in our society, taking advantage of their positive attributes and minimizing their negative ones. We need to understand better how to reverse the negative impact of media and make it more positive. PMID:20683108

EarthScope's Education, Outreach, and Communications: Using Social Media from Continental to Global Scales  

NASA Astrophysics Data System (ADS)

Social media has emerged as a popular and effective form of communication among all age groups, with nearly half of Internet users belonging to a social network or using another form of social media on a regular basis. This phenomenon creates an excellent opportunity for earth science organizations to use the wide reach, functionality and informal environment of social media platforms to disseminate important scientific information, create brand recognition, and establish trust with users. Further, social media systems can be utilized for missions of education, outreach, and communicating important timely information (e.g., news agencies are common users). They are eminently scaleable (thus serving from a few to millions of users with no cost and no performance problem), searchable (people are turning to them more frequently as conduits for information), and user friendly (thanks to the massive resources poured into the underlying technology and design, these systems are easy to use and have been widely adopted). They can be used, therefore, to engage the public interactively with the EarthScope facilities, experiments, and discoveries, and continue the cycle of discussions, experiments, analysis and conclusions that typify scientific advancement. The EarthScope National Office (ESNO) is launching an effort to utilize social media to broaden its impact as a conduit between scientists, facilities, educators, and the public. The ESNO will use the opportunities that social media affords to offer high quality science content in a variety of formats that appeal to social media users of various age groups, including blogs (popular with users 18-29), Facebook and Twitter updates (popular with users ages 18-50), email updates (popular with older adults), and video clips (popular with all age groups). We will monitor the number of "fans" and "friends" on social media and networking pages in order to gauge the increase in the percentage of the user population visiting the site. We will also use existing tools available on social media sites to track the relationships between users who visit or "friend" the site to determine how knowledge of the site is transferred amongst various social, educational or geographic groups. Finally, we will use this information to iteratively improve the variety of content and media on the site to increase our user pool, improve EarthScope recognition, and provide appropriate and user-specific Earth science information, especially for time sensitive events of wide interest such as natural disasters.

AAAS Mass Media Science and Engineering Fellowship Program: Building Communication Skills in Young Scientists  

NASA Astrophysics Data System (ADS)

The AAAS Mass Media Science &Engineering Fellowship program has succeeded in training scientists to become more effective communicators for more than 30 years. The program places advanced science, engineering and mathematics students at media sites to work as science reporters for ten weeks each summer. AAAS places between 15 to 20 students a year at newspapers, magazines and radio stations. Our goal is to create better science communicators who understand their role in fostering the public's understanding of science. Fellows leave the program with a greater awareness of how to communicate complex issues by making the connection as to why people should be interested in certain developments, and more specifically, how they will impact their communities. 2004 AGU Fellow Rei Ueyama put her lessons learned to good use during her Fellowship at the Sacramento Bee. "In a regional paper like The Bee, a (story) also had to have a local touch. I needed to show why people in Sacramento (or California) should bother to read the story. One example is the story I wrote about seeding the ocean with iron particles to fight global warming. Since ocean fertilization is a global issue, I had to clearly specify the reason why The Bee and not The New York Times was running the story. The local angle I chose was to point out that the core group of scientists involved in this study was from Monterey Bay, Calif." Many alumni tell us the program has been an integral force in shaping the course of their career. Similarly, sites often report that having a scientist on staff is an invaluable resource that allows them to cover additional science stories as well as report some technical stories in more depth. The American Geophysical Union has sponsored a Mass Media Fellow since 1997. Sponsorship allows affiliate program partners to establish connections with young professionals in their field. They are then also able to take advantage of the communication skills resident in their alumni base. The OS28 Communicating Broadly: Perspectives and Tools for Ocean, Earth and Atmospheric Scientists Session would provide an ideal platform for Fellowship management to share lessons learned about science communication and to offer insight as to the challenges scientists face when communicating with the general public or media.

The value and use of social media as communication tool in the plant sciences  

PubMed Central

Social media now complements many parts of our lives. Facebook, Twitter, YouTube and many other social networking sites allow users to share and interact with online content and to connect with like-minded people. Its strengths – rapid dissemination and amplification of content and the ability to lead informal conversations – make it a powerful tool to use in a professional context. This commentary explains the overall concept of social media and offers suggestions on usage and possible types of scientific content. It advises researchers on the potential benefits and how to take a strategic approach towards building a social media presence. It also presents examples of effective social media use within the plant science community. Common reasons for scientists to not engage with social media include the fear of appearing unprofessional, posting something wrong or being misunderstood, or a lack of confidence in their computer skills. With the rapid changes in academic publishing, dissemination and science communication, as well as the rise of ‘altmetrics’ to track online engagement with scientific content, digital literacy will become an essential skill in a scientist’s tool kit.

Measuring engagement effectiveness in social media  

NASA Astrophysics Data System (ADS)

Social media is becoming increasingly prevalent with the advent of web 2.0 technologies. Popular social media websites, such as Twitter and Facebook, are attracting a gigantic number of online users to post and share information. An interesting phenomenon under this trend involves that more and more users share their experiences or issues with regard to a product, and then the product service agents use commercial social media listening and engagement tools (e.g. Radian6, Sysomos, etc.) to response to users' complaints or issues and help them tackle their problems. This is often called customer care in social media or social customer relationship management (CRM). However, all these existing commercial social media tools only provide an aggregated level of trends, patterns and sentiment analysis based on the keyword-centric brand relevant data, which have little insights for answering one of the key questions in social CRM system: how effective is our social customer care engagement? In this paper, we focus on addressing the problem of how to measure the effectiveness of engagement for service agents in customer care. Traditional CRM effectiveness measurements are defined under the scenario of the call center, where the effectiveness is mostly based on the duration time per call and/or number of answered calls per day. Different from customer care in a call center, we can obtain detailed conversations between agents and customers in social media, and therefore the effectiveness can be measured by analyzing the content of conversations and the sentiment of customers.

Communication about scientific uncertainty in environmental nanoparticle research - a comparison of scientific literature and mass media  

NASA Astrophysics Data System (ADS)

The research about the fate and behavior of engineered nanoparticles in the environment is despite its wide applications still in the early stages. 'There is a high level of scientific uncertainty in nanoparticle research' is often stated in the scientific community. Knowledge about these uncertainties might be of interest to other scientists, experts and laymen. But how could these uncertainties be characterized and are they communicated within the scientific literature and the mass media? To answer these questions, the current state of scientific knowledge about scientific uncertainty through the example of environmental nanoparticle research was characterized and the communication of these uncertainties within the scientific literature is compared with its media coverage in the field of nanotechnologies. The scientific uncertainty within the field of environmental fate of nanoparticles is by method uncertainties and a general lack of data concerning the fate and effects of nanoparticles and their mechanisms in the environment, and by the uncertain transferability of results to the environmental system. In the scientific literature, scientific uncertainties, their sources, and consequences are mentioned with different foci and to a different extent. As expected, the authors in research papers focus on the certainty of specific results within their specific research question, whereas in review papers, the uncertainties due to a general lack of data are emphasized and the sources and consequences are discussed in a broader environmental context. In the mass media, nanotechnology is often framed as rather certain and positive aspects and benefits are emphasized. Although reporting about a new technology, only in one-third of the reports scientific uncertainties are mentioned. Scientific uncertainties are most often mentioned together with risk and they arise primarily from unknown harmful effects to human health. Environmental issues itself are seldom mentioned. Scientific uncertainties, sources, and consequences have been most widely discussed in the review papers. Research papers and mass media tend to emphasize more the certainty of their scientific results or the benefits of the nanotechnology applications. Neither the broad spectrum nor any specifications of uncertainties have been communicated. This indicates that there has been no effective dialogue over scientific uncertainty with the public so far.

A New Dimension of Health Care: Systematic Review of the Uses, Benefits, and Limitations of Social Media for Health Communication  

PubMed Central

Background There is currently a lack of information about the uses, benefits, and limitations of social media for health communication among the general public, patients, and health professionals from primary research. Objective To review the current published literature to identify the uses, benefits, and limitations of social media for health communication among the general public, patients, and health professionals, and identify current gaps in the literature to provide recommendations for future health communication research. Methods This paper is a review using a systematic approach. A systematic search of the literature was conducted using nine electronic databases and manual searches to locate peer-reviewed studies published between January 2002 and February 2012. Results The search identified 98 original research studies that included the uses, benefits, and/or limitations of social media for health communication among the general public, patients, and health professionals. The methodological quality of the studies assessed using the Downs and Black instrument was low; this was mainly due to the fact that the vast majority of the studies in this review included limited methodologies and was mainly exploratory and descriptive in nature. Seven main uses of social media for health communication were identified, including focusing on increasing interactions with others, and facilitating, sharing, and obtaining health messages. The six key overarching benefits were identified as (1) increased interactions with others, (2) more available, shared, and tailored information, (3) increased accessibility and widening access to health information, (4) peer/social/emotional support, (5) public health surveillance, and (6) potential to influence health policy. Twelve limitations were identified, primarily consisting of quality concerns and lack of reliability, confidentiality, and privacy. Conclusions Social media brings a new dimension to health care as it offers a medium to be used by the public, patients, and health professionals to communicate about health issues with the possibility of potentially improving health outcomes. Social media is a powerful tool, which offers collaboration between users and is a social interaction mechanism for a range of individuals. Although there are several benefits to the use of social media for health communication, the information exchanged needs to be monitored for quality and reliability, and the users’ confidentiality and privacy need to be maintained. Eight gaps in the literature and key recommendations for future health communication research were provided. Examples of these recommendations include the need to determine the relative effectiveness of different types of social media for health communication using randomized control trials and to explore potential mechanisms for monitoring and enhancing the quality and reliability of health communication using social media. Further robust and comprehensive evaluation and review, using a range of methodologies, are required to establish whether social media improves health communication practice both in the short and long terms.

Negotiated media effects. Peer feedback modifies effects of media's thin-body ideal on adolescent girls.  

PubMed

The present study introduces a theoretical framework on negotiated media effects. Specifically, we argue that feedback of peers on thin-body ideal media images and individual dispositions guide effects on adolescent girls' psychosocial responses to media exposure. Therefore, we examined the thin-body ideal as portrayed in media and peers' feedback on such thin-ideal images in their combined effects on adolescent girls' body dissatisfaction, objectified body consciousness, and social comparison with media models. Hence, media models and peer comments were systematically combined as incorporated entities in YouTube-formats. Hypotheses were tested in a 3 (media models: extremely thin vs. thin vs. normal weight)×3 (peer comments: 6kg-underweight vs. 3kg-underweight vs. normal-weight)×2 (appearance schematicity: lower vs. higher) between-subjects design (N=216). Results showed that peer comments indicating that a media model was 'only 3kg-underweight' exerted most negative responses, particularly in girls who strongly process appearance relevant information. Peer feedback interacts with media models in guiding perceptions of what is considered an 'ideal' body shape. Results highlight the important role of peers as well as individual predispositions in view of understanding how thin-ideal media images may impact adolescent girls' body image concerns.

We develop hypotheses based on the proposition that synchronous communication media are perceived to be more effective for convergence communication while asynchronous communication media are perceived to be more suitable for conveyance communication. These hypotheses were tested using

Climate Change Media Forum - for Enhanced Communication between Journalists and Climate Scientists in Japan  

NASA Astrophysics Data System (ADS)

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 target and possible impacts by the temperature rise, the participants discussed reporting of target selected from data with uncertainty. The third forum event was held in February, 2011, on climate change projections by numerical models. After the lecture on the ongoing projects of climate change prediction for AR5 in Japan, one of the presenters at the press conference on climate change projections for AR4 in 2007 shared his own thoughts on the media reports based on the press conference. In the following session, the researchers and journalists actively discussed how the climate change projection should be reported based on their own "mission" which is conducting reliable research for scientists and writing informative articles for journalists. Through the previous three events, we have obtained sincere comments and suggestions from the participants to improve the communication between journalists and researchers. In the presentation, more comments from the discussions and the survey results of the forum events will be shared.

Physics collaboration and communication through emerging media: *odcasts, blogs and wikis  

NASA Astrophysics Data System (ADS)

The entertainment and news industries are being transformed by the emergence of innovative, internet-based media tools. Audio and video downloads are beginning to compete with traditional entertainment distribution channels, and the blogosphere has become an alternative press with demonstrated news-making power of its own. The scientific community, and physics in particular, is just beginning to experiment with these tools. We believe that they have great potential for enhancing the quality and effectiveness of collaboration and communication, and that the coming generation of physicists will expect them to be used creatively. We will report on our experience in producing seminar podcasts (google ``QIBEC'' or search ``quantum'' on Apple iTunes), and on operating a distributed research institute using a group-based blog.

The Great Puerto Rico ShakeOut - A Communications and Media Perspective  

NASA Astrophysics Data System (ADS)

On October 18, 2012 the Puerto Rico Seismic Network (PRSN) in collaboration with Puerto Rico Emergency Management Agency (PREMA) and the Federal Emergency Management Agency (FEMA) will be conducting the first Great Puerto Rico ShakeOut. Adequate communications strategies and redundant dissemination methods are a key component for the success of this earthquake exercise. EAS and NOAA Radio messages, indicating the beginning of the earthquake drill, will help emergency managers and the general public better coordinate their practices. Dissemination tools routinely used as part of PRSN earthquake and tsunami protocols, such as PRSNDANIS Broadcast, Ring Down, Ham Radio, RSS, SMS, fax and email service lists, will also be tested. Emergency Management and First Response Agencies at local, regional and state level are being asked to report the times the messages are received, thus allowing us to better assess the effectiveness of our dissemination methods and to establish a baseline for next year ShakeOut. In addition, a partnership with the Puerto Rico Radiobroadcaster Association allows a direct access through this media, facilitating PRSN staff participation on radio programming targeting diverse audiences. Radio spots have been developed to inform the public about the exercise, how to participate, what to do to be safe during an earthquake and how to develop or improve their safety plans. A media approach is critical for the success of the 2012 Puerto Rico ShakeOut since our earthquake drill takes place 2 weeks prior to the Island general election and on the peak-period of the hurricane season.

Effective Usage of Social Media for Dark Skies Awareness  

NASA Astrophysics Data System (ADS)

Social media has become a daily tool in our culture. Networks such as Facebook with 900 million active users and Twitter with 140 million active users make an ideal platform to create awareness. It helps to generate and share new content and enables multi-communication channels. This presentation will address how effectively social media can be used as an education tool to create awareness of light pollution. As a "green" focus becomes more important in our world the topic of light pollution is also rising as an important issue. Light Pollution affects many aspects of our world ranging from flora and fauna to the economic well-being of many industrialized countries. Mixed among the many important pollutants in our world light pollution can fall by the way-side, forgotten, but it is imperative to bring out awareness of this problem, especially since studies are beginning to show how by fighting light pollution we will also be fighting other pollution such as air pollutants. GLOBE at Night has combined social media tools such as Facebook and Twitter with its educational awareness campaign on light pollution to reach out to social media community. Currently our Facebook reaches citizens of twenty separate countries ranging from the Czech Republic and Peru to the United States and the United Kingdom. On Facebook our reach is estimated at over 800,000 friends of our fans. These networks help us to directly answer users' immediate questions and encourage participation in the GLOBE at Night campaigns. Important news on light pollution appearing in cyberspace is monitored regularly using Google Alerts and Twitter hash tags filters which gets posted regularly on our networks. Social media networking has become a tool for users not only for information about GLOBE at Night but also for information about the overall topic of light pollution itself. Many individuals and organizations struggle with the mass content shared in social networks. It is important to know where to look for the right content and what to share with whom. This presentation will highlight on; the importance of engaging in social media to gain and share new content, how to filter the right content, and best uses of social media to create an awareness of light pollution. We will discuss the proper ways to get the most use out of social media networking.

Transmedia Storytelling in Science Communication: One Subject, Multiple Media, Multiple Stories  

NASA Astrophysics Data System (ADS)

Each communication medium has particular storytelling strengths. For example, video is particularly good at illustrating a progression of events, text at background and context, and games at describing systems. In what USC's Prof. Henry Jenkins described as "transmedia storytelling," multiple media are used simultaneously, in an expansive rather than repetitive way, to better tell a single, complex story. The audience is given multiple entry points to the story, and the story is exposed to diverse and dispersed audiences, ultimately engaging a broader public. We will examine the effectiveness of a transmedia approach to communicating scientific and other complex concepts to a broad and diverse audience. Using the recently developed Educational Visitor Center at the NCAR-Wyoming Supercomputing Center as a case study, we will evaluate the reach of various means of presenting information about the geosciences, climate change and computational science. These will include an assessment of video, mechanical and digital interactive elements, animated movie segments, web-based content, photography, scientific visualizations, printed material and docent-led activities.

The effects of the transmission media - the earth's troposphere and ionosphere, and the solar wind - on precise Doppler tracking are discussed. The charged particle effects can be largely removed by dual frequency observations; however there are limitations to these corrections (besides system noise and/or finite integration times) including the effects of magnetic fields, diffraction, and differential refraction, all of which must be carefully evaluated. The earth's troposphere can contribute an error of delta f/f approximately 10 to the minus 14th power.

A systematic review of the use and effectiveness of social media in child health  

PubMed Central

Background Social media use is highly prevalent among children, youth, and their caregivers, and its use in healthcare is being explored. The objective of this study was to conduct a systematic review to determine: 1) for what purposes social media is being used in child health and its effectiveness; and 2) the attributes of social media tools that may explain how they are or are not effective. Methods We searched Medline, CENTRAL, ERIC, PubMed, CINAHL, Academic Search Complete, Alt Health Watch, Health Source, Communication and Mass Media Complete, Web of Knowledge, and Proquest Dissertation and Theses Database from 2000–2013. We included primary research that evaluated the use of a social media tool, and targeted children, youth, or their families or caregivers. Quality assessment was conducted on all included analytic studies using tools specific to different quantitative designs. Results We identified 25 studies relevant to child health. The majority targeted adolescents (64%), evaluated social media for health promotion (52%), and used discussion forums (68%). Most often, social media was included as a component of a complex intervention (64%). Due to heterogeneity in conditions, tools, and outcomes, results were not pooled across studies. Attributes of social media perceived to be effective included its use as a distraction in younger children, and its ability to facilitate communication between peers among adolescents. While most authors presented positive conclusions about the social media tool being studied (80%), there is little high quality evidence of improved outcomes to support this claim. Conclusions This comprehensive review demonstrates that social media is being used for a variety of conditions and purposes in child health. The findings provide a foundation from which clinicians and researchers can build in the future by identifying tools that have been developed, describing how they have been used, and isolating components that have been effective.

Internet and Social Media For Health-Related Information and Communication in Health Care: Preferences of the Dutch General Population  

PubMed Central

Background Health care is increasingly featured by the use of Web 2.0 communication and collaborative technologies that are reshaping the way patients and professionals interact. These technologies or tools can be used for a variety of purposes: to instantly debate issues, discover news, analyze research, network with peers, crowd-source information, seek support, and provide advice. Not all tools are implemented successfully; in many cases, the nonusage attrition rates are high. Little is known about the preferences of the Dutch general population regarding the use of the Internet and social media in health care. Objective To determine the preferences of the general population in the Netherlands regarding the use of the Internet and social media in health care. Methods A cross-sectional survey was disseminated via a popular Dutch online social network. Respondents were asked where they searched for health-related information, how they qualified the value of different sources, and their preferences regarding online communication with health care providers. Results were weighed for the Dutch population based on gender, age, and level of education using official statistics. Numbers and percentages or means and standard deviations were presented for different subgroups. One-way ANOVA was used to test for statistical differences. Results The survey was completed by 635 respondents. The Internet was found to be the number one source for health-related information (82.7%), closely followed by information provided by health care professionals (71.1%). Approximately one-third (32.3%) of the Dutch population search for ratings of health care providers. The most popular information topics were side effects of medication (62.5%) and symptoms (59.7%). Approximately one-quarter of the Dutch population prefer to communicate with a health care provider via social media (25.4%), and 21.2% would like to communicate via a webcam. Conclusions The Internet is the main source of health-related information for the Dutch population. One in 4 persons wants to communicate with their physician via social media channels and it is expected that this number will further increase. Health care providers should explore new ways of communicating online and should facilitate ways for patients to connect with them. Future research should aim at comparing different patient groups and diseases, describing best practices, and determining cost-effectiveness. PMID:24088272

The successful ability to efficiently collect diet histories, convey appropriate health messages, and discuss client concerns about the safe feeding of pets requires excellent communication skills. In addition to understanding what the client wants for their pet, thorough nutritional interviewers gather information pertaining to animal factors, dietary factors, and feeding management factors. With the expansion of the Internet, increasing advances in medical care, and the health concerns associated with pet food recalls, small animal clients are looking to veterinarians for guidance and information on dietary recommendations in ever increasing numbers. Evaluating current information on changes in the pet food industry should be a periodic learning objective for all members of the veterinary health care team.

A self-adaptive method for creating high efficiency communication channels through random scattering media  

NASA Astrophysics Data System (ADS)

Controlling the propagation of electromagnetic waves is important to a broad range of applications. Recent advances in controlling wave propagation in random scattering media have enabled optical focusing and imaging inside random scattering media. In this work, we propose and demonstrate a new method to deliver optical power more efficiently through scattering media. Drastically different from the random matrix characterization approach, our method can rapidly establish high efficiency communication channels using just a few measurements, regardless of the number of optical modes, and provides a practical and robust solution to boost the signal levels in optical or short wave communications. We experimentally demonstrated analog and digital signal transmission through highly scattering media with greatly improved performance. Besides scattering, our method can also reduce the loss of signal due to absorption. Experimentally, we observed that our method forced light to go around absorbers, leading to even higher signal improvement than in the case of purely scattering media. Interestingly, the resulting signal improvement is highly directional, which provides a new means against eavesdropping.

Bio-objects and the media: the role of communication in bio-objectification processes  

PubMed Central

The representation of biological innovations in and through communication and media practices is vital for understanding the nature of “bio-objects” and the process we call “bio-objectification.” This paper discusses two ideal-typical analytical approaches based on different underlying communication models, ie, the traditional (science- and media-centered) and media sociological (a multi-layered process involving various social actors in defining the meanings of scientific and technological developments) approach. In this analysis, the latter is not only found to be the most promising approach for understanding the circulation, (re)production, and (re)configuration of meanings of bio-objects, but also to interpret the relationship between media and science. On the basis of a few selected examples, this paper highlights how media function as a primary arena for the (re)production and (re)configuration of scientific and biomedical information with regards to bio-objects in the public sphere in general, and toward decision-makers, interest groups, and the public in specific.

Media use, face-to-face communication, media multitasking, and social well-being among 8- to 12-year-old girls.  

PubMed

An online survey of 3,461 North American girls ages 8-12 conducted in the summer of 2010 through Discovery Girls magazine examined the relationships between social well-being and young girls' media use--including video, video games, music listening, reading/homework, e-mailing/posting on social media sites, texting/instant messaging, and talking on phones/video chatting--and face-to-face communication. This study introduced both a more granular measure of media multitasking and a new comparative measure of media use versus time spent in face-to-face communication. Regression analyses indicated that negative social well-being was positively associated with levels of uses of media that are centrally about interpersonal interaction (e.g., phone, online communication) as well as uses of media that are not (e.g., video, music, and reading). Video use was particularly strongly associated with negative social well-being indicators. Media multitasking was also associated with negative social indicators. Conversely, face-to-face communication was strongly associated with positive social well-being. Cell phone ownership and having a television or computer in one's room had little direct association with children's socioemotional well-being. We hypothesize possible causes for these relationships, call for research designs to address causality, and outline possible implications of such findings for the social well-being of younger adolescents.

Linguistic Input, Electronic Media, and Communication Outcomes of Toddlers with Hearing Loss  

PubMed Central

Objectives The objectives of this study were to examine the quantity of adult words, adult-child conversational turns, and electronic media in the auditory environments of toddlers who are hard of hearing (HH) and to examine whether these variables contributed to variability in children’s communication outcomes. Design Participants were 28 children with mild to severe hearing loss. Full-day recordings of children’s auditory environments were collected within 6 months of their 2nd birthdays by utilizing LENA (Language ENvironment Analysis) technology. The system analyzes full-day acoustic recordings, yielding estimates of the quantity of adult words, conversational turns, and electronic media exposure in the recordings. Children’s communication outcomes were assessed via the receptive and expressive scales of the Mullen Scales of Early Learning at 2 years of age and the Comprehensive Assessment of Spoken Language at 3 years of age. Results On average, the HH toddlers were exposed to approximately 1400 adult words per hour and participated in approximately 60 conversational turns per hour. An average of 8% of each recording was classified as electronic media. However, there was considerable within-group variability on all three measures. Frequency of conversational turns, but not adult words, was positively associated with children’s communication outcomes at 2 and 3 years of age. Amount of electronic media exposure was negatively associated with 2-year-old receptive language abilities; however, regression results indicate that the relationship was fully mediated by the quantity of conversational turns. Conclusions HH toddlers who were engaged in more conversational turns demonstrated stronger linguistic outcomes than HH toddlers who were engaged in fewer conversational turns. The frequency of these interactions was found to be decreased in households with high rates of electronic media exposure. Optimal language-learning environments for HH toddlers include frequent linguistic interactions between parents and children. To support this goal, parents should be encouraged to reduce their children’s exposure to electronic media. PMID:24441740

A surfeit of science: The "CSI effect" and the media appropriation of the public understanding of science.  

PubMed

Over the past decade, popular media has promulgated claims that the television program CSI and its spinoffs and imitators have had a pernicious effect on the public understanding of forensic science, the so-called "CSI effect." This paper analyzes those media claims by documenting the ways in which the media claims that CSI "distorts" an imagined "reality." It shows that the media appropriated the analytic stance usually adopted by science advocates, portraying the CSI effect as a social problem in science communication. This appropriation was idiosyncratic in that it posited, as a social problem, a "surfeit" of knowledge and positive imagery about science, rather than the more familiar "deficits." In addition, the media simultaneously appropriated both "traditional" and "critical" PUS discourses. Despite this apparent contradiction, the paper concludes that, in both discourses, the media and its expert informants insist upon their hegemony over "the public" to articulate the "reality" of forensic science.

Using mass-media communications to increase population usage of Australia’s Get Healthy Information and Coaching Service®  

PubMed Central

Background Global obesity prevalence is increasing and population health programs are required to support changes to modifiable lifestyle risk factors. Such interventions benefit from mass-communications to promote their use. The Get Healthy Information and Coaching Service ® (GHS) utilised mass-reach media advertising to recruit participants to an Australian state-wide program. Methods A stand alone population survey collected awareness, knowledge and behavioural variables before the first advertising phase, (n?=?1,544; August -September 2010), during (n?=?1,500; February - March 2011) and after the advertising period (n?=?1,500; June-July 2011). GHS usage data (n?=?6,375) was collated during July 2010 – June 2011. Results The results showed that television-lead mass-media significantly increased unprompted awareness (0% to 31.8%, p?media (television, print and mail out information) was more often cited as the source of referral by males, those aged 18 – 49?years, employed, and from the lowest socio-economic groups. During the weeks when mass-media advertising was present, 4 and 2.5 times more information and coaching participants respectively registered than when there was no advertising present. Participants who cited television and print were less likely to enrol in GHS coaching, but this was not the case for mail out information and secondary referral sources. Conclusions GHS mass-communications campaigns are effective at increasing awareness and usage of the GHS, especially among hard-to-reach population groups. Television advertising provides universal reach, but should be supplemented by health professional referrals and targeted mail-out information to recruit participants to the intensive GHS coaching program.

Modelling the effects of media during an influenza epidemic  

PubMed Central

Background Mass media is used to inform individuals regarding diseases within a population. The effects of mass media during disease outbreaks have been studied in the mathematical modelling literature, by including ‘media functions’ that affect transmission rates in mathematical epidemiological models. The choice of function to employ, however, varies, and thus, epidemic outcomes that are important to inform public health may be affected. Methods We present a survey of the disease modelling literature with the effects of mass media. We present a comparison of the functions employed and compare epidemic results parameterized for an influenza outbreak. An agent-based Monte Carlo simulation is created to access variability around key epidemic measurements, and a sensitivity analysis is completed in order to gain insight into which model parameters have the largest influence on epidemic outcomes. Results Epidemic outcome depends on the media function chosen. Parameters that most influence key epidemic outcomes are different for each media function. Conclusion Different functions used to represent the effects of media during an epidemic will affect the outcomes of a disease model, including the variability in key epidemic measurements. Thus, media functions may not best represent the effects of media during an epidemic. A new method for modelling the effects of media needs to be considered. PMID:24742139

Shared identity is key to effective communication.  

PubMed

The ability to communicate with others is one of the most important human social functions, yet communication is not always investigated from a social perspective. This research examined the role that shared social identity plays in communication effectiveness using a minimal group paradigm. In two experiments, participants constructed a model using instructions that were said to be created by an ingroup or an outgroup member. Participants made models of objectively better quality when working from communications ostensibly created by an ingroup member (Experiments 1 and 2). However, this effect was attenuated when participants were made aware of a shared superordinate identity that included both the ingroup and the outgroup (Experiment 2). These findings point to the importance of shared social identity for effective communication and provide novel insights into the social psychology of communication. PMID:25416042

Communication Satellite Technology and Multi-Media Demonstration on-Board ISS  

NASA Astrophysics Data System (ADS)

The paper presents ongoing preparative activities and the opportunities for a utilization of the European ISS Module COLUMBUS as a testbed for communications and multimedia technology. This can provide a new service to the commercially oriented Space Communication Community and Parties interested in tests of space bound terrestrial applications (e.g. telematics). For this purpose, Astrium SI, Bremen, has studied several options how to test and verify advanced Multi-Media / Broadband Communications of Non-Geostationary Systemes. These activities have been conducted in cooperation with, and/or under contract of, DLR and ESA/ESTEC. With an accordingly equipped platform on-board the European ISS Module COLUMBUS a generic test-bed for Multi- Media-Services, inter-orbit link technology and other to be verified and demonstrated technology may be derived. The advantages of such an universal test service are obvious: - Crew accessibility / maintainability - Return of hardware after test to earth possible - Exposure of equipment to space environment - Fast to be installed experiments (compared to satellite missions) - Reasonable effort by shared installation costs (esp. compared to GEO missions) This may result in a new kind of technology demo missions (e.g. commercial parts applications, experiments of to-the-need scalable duration etc.).

Health effects of media on children and adolescents.  

PubMed

Youth spend an average of >7 hours/day using media, and the vast majority of them have access to a bedroom television, computer, the Internet, a video-game console, and a cell phone. In this article we review the most recent research on the effects of media on the health and well-being of children and adolescents. Studies have shown that media can provide information about safe health practices and can foster social connectedness. However, recent evidence raises concerns about media's effects on aggression, sexual behavior, substance use, disordered eating, and academic difficulties. We provide recommendations for parents, practitioners, the media, and policy makers, among others, for ways to increase the benefits and reduce the harm that media can have for the developing child and for adolescents.

Public and Media Communication of Volcanic Hazard Before and During the 2010 Eruption in Eyjafjallajökull, Iceland  

NASA Astrophysics Data System (ADS)

The 39 day long explosive eruption in Eyjafjallajökull was the largest natural hazard event in Iceland for decades. It began with a small flank eruption in March, but the main event was the explosive summit eruption. The flooding that resulted from melting of ice at the eruption site posed considerable danger for the local population, fallout of ash made conditions south of the volcano difficult for several weeks, threatening the future of farming in this rural area, and lead to unprecedented disruption to air traffic in Europe and the North Atlantic. About 800 people were evacuated in a hurry three times during these events because of imminent flood hazard, but fortunately no dwellings were damaged and people could usually return to their homes the same day. These events called for extensive media coverage, both locally and internationally. Some staff at research institutes had for several days to devote their time exclusively to giving interviews to the international media. Scientific communication with the local population was mainly conducted through four channels: (1) the web pages of institutions, (2) the national media; (3) indirectly at meetings on the status of the eruption with local and national officials, and (4) public meetings in the affected areas. In addition the scientific community issued daily status reports to the Department of Civil Protection and Emergency Management, these reports served both national and local Civil Protection officials when preparing their statements on the eruption and answer basic questions from the media. During media communication, it is important to stick to facts, avoid speculation and use plain language without scientific jargon. However, the most critical part of the communication occurred in the years before the eruption through meetings with the local inhabitants. At these meetings the results of a detailed hazard assessment on eruptions in Eyjafjallajökull and the neighboring ice-filled Katla caldera where presented to the communities around these volcanoes. The most dangerous hazard is large scale floods due to melting of glacier ice in eruptions. Further meetings took place where evacuation plans for areas potentially impacted by flooding were presented. These plans have been updated through dialogue with the inhabitants and a drill was held in 2006, where people evacuated their homes and moved to safer ground in nearby villages. This extensive preparation was possible not least because of very active leadership by the local chief of police, his staff and the national coordination body for Civil Protection i.e. the Department of Civil Protection and Emergency Management. The preparatory meetings provided a very important background for officials, scientists and the local inhabitants. Where communities are small, trust is most easily established through face to face contact at local meetings.

Social media and its dual use in biopreparedness: communication and visualization tools in an animal bioterrorism incident.  

PubMed

This article focuses on social media and interactive challenges for emergency organizations during a bioterrorism or agroterrorism incident, and it outlines the dual-use dilemma of social media. Attackers or terrorists can use social media as their modus operandi, and defenders, including emergency organizations in law enforcement and public and animal health, can use it for peaceful purposes. To get a better understanding of the uses of social media in these situations, a workshop was arranged in Stockholm, Sweden, to raise awareness about social media and animal bioterrorism threats. Fifty-six experts and crisis communicators from international and national organizations participated. As a result of the workshop, it was concluded that emergency organizations can collect valuable information and monitor social media before, during, and after an outbreak. In order to make use of interactive communication to obtain collective intelligence from the public, emergency organizations must adapt to social networking technologies, requiring multidisciplinary knowledge in the fields of information, communication, IT, and biopreparedness. Social network messaging during a disease outbreak can be visualized in stream graphs and networks showing clusters of Twitter and Facebook users. The visualization of social media can be an important preparedness tool in the response to bioterrorism and agroterrorism. PMID:23971817

Making media work in space: an interdisciplinary perspective on media and communication requirements for current and future space communities  

NASA Astrophysics Data System (ADS)

As humans expand into space communities will form. These have already begun to form in small ways, such as long-duration missions on the International Space Station and the space shuttle, and small-scale tourist excursions into space. Social, behavioural and communications data emerging from such existing communities in space suggest that the physically-bounded, work-oriented and traditionally male-dominated nature of these extremely remote groups present specific problems for the resident astronauts, groups of them viewed as ‘communities’, and their associated groups who remain on Earth, including mission controllers, management and astronauts’ families. Notionally feminine group attributes such as adaptive competence, social adaptation skills and social sensitivity will be crucial to the viability of space communities and in the absence of gender equity, ‘staying in touch’ by means of ‘news from home’ becomes more important than ever. A template of news and media forms and technologies is suggested to service those needs and enhance the social viability of future terraforming activities.

Communication - An Effective Tool for Implementing ISO 14001/EMS  

SciTech Connect

The Idaho National Engineering and Environmental Laboratory (INEEL) received ISO 14001/EMS certification in June 2002. Communication played an effective role in implementing ISO 14001/EMS at the INEEL. This paper describes communication strategies used during the implementation and certification processes. The INEEL achieved Integrated Safety Management System (ISMS) and Voluntary Protection Program (VPP) Star status in 2001. ISMS implemented a formal process to plan and execute work. VPP facilitated worker involvement by establishing geographic units at various facilities with employee points of contact and management champions. The INEEL Environmental Management System (EMS) was developed to integrate the environmental functional area into its ISMS and VPP. Since the core functions of ISMS, VPP, and EMS are interchangeable, they were easy to integrate. Communication is essential to successfully implement an EMS. (According to ISO 14001 requirements, communication interacts with 12 other elements of the requirements.) We developed communication strategies that integrated ISMS, VPP, and EMS. For example, the ISMS, VPP, and EMS Web sites communicated messages to the work force, such as “VPP emphasizes the people side of doing business, ISMS emphasizes the system side of doing business, and EMS emphasizes the systems to protect the environment; but they all define work, identify and analyze hazards, and mitigate the hazards.” As a result of this integration, the work force supported and implemented the EMS. In addition, the INEEL established a cross-functional communication team to assist with implementing the EMS. The team included members from the Training and Communication organizations, VPP office, Pollution Prevention, Employee and Media Relations, a union representative, facility environmental support, and EMS staff. This crossfunctional team used various communication strategies to promote our EMS to all organization levels and successfully implemented EMS activities through VPP geographic units. In summary, the ISMS and VPP process at the INEEL provided the basic framework of management support and worker involvement to implement our EMS. A cross-functional communication team was established to facilitate the implementation with great success. Communication has been an effective tool for implementing an ISO 14001/EMS at the INEEL.

Effects of alternative communication on the communicative effectiveness of an individual with a progressive language disorder.  

PubMed

This study was designed to investigate the effects of two different modes of communication on the communicative output of an individual who is no longer able to communicate verbally, presenting with a primary progressive aphasia and apraxia of speech. The two treatment approaches included training the patient with a text-to-speech alternative communication device and with American sign language. An alternating treatment design was used to compare two communicative approaches (an alternative communication device and American sign language) on the subject's communicative effectiveness. Communicative effectiveness was measured in terms of number of words, correct information units and percentage correct information units, using a protocol that was adapted to quantify the output generated by the alternative communication device and American sign language. Increases across all three measures resulted for both the alternative communication device and American sign language. The clinical implications are explored, and the results add to existing studies regarding treatment possibilities using alternative communication for individuals who present with a progressive speech and language disorder, without concomitant cognitive deficits.

The analytical expressions for the normalized average mass flux and pressure drop for power law fluids for wall effects in porous media are presented by using the fractal theory and technique for porous media. The proposed models are expressed as functions of power law index and structure parameters. These model predictions show that the proposed models can provide a good agreement with the experimental and other analytical results. This indicates that the fractal models may be helpful to much better understand the mechanisms of flow than other analytical models for porous media.

Interface effects on dose distributions in irradiated media  

SciTech Connect

It has long been recognized that nonuniformities in dose distributions may occur in the immediate vicinity of a boundary between two different media. Considerable work has been done to determine interface effects in media irradiated by photons or in media containing ..beta..- or ..cap alpha..-particle emitters. More recently interface effects have become of interest in additional problems, including pion radiotherapy and radiation effects in electronic microcircuits in space vehicles. These problems arise when pion capture stars or proton-nucleus interactions produce a spectrum of charged nuclear fragments near an interface. The purpose of this paper is to examine interface effects in detail as to their specific origin. We have made Monte Carlo calculations of dose distributions near an interface in a systematic way for a number of idealized cases in order to indicate the separate influences of several factors including different stopping powers of the two media, nonconstancy (e.g., Bragg peak) in the energy loss curve for the particles, different particle spectra in the two media, and curvature of the boundary between the two media.

Parallel domain decomposition method with non-blocking communication for flow through porous media  

NASA Astrophysics Data System (ADS)

This paper introduces a domain decomposition method for numerically solving the Stokes equation for very large, complex geometries. Examples arise from realistic porous media. The computational method is based on the SIMPLE (Semi-Implicit Method for Pressure Linked Equations) algorithm which uses a finite-differences approach for discretizing the underlying equations. It achieves comparable speed and efficiency as lattice Boltzmann methods. The domain decomposition method splits a large three-dimensional region into slices that can be processed in parallel on multi-processor computation environments with only minimal communication between the computation nodes. With this method, the flow through a porous medium with grid sizes up to 20483 voxel has been calculated.

Communicating more effectively with public audiences (Invited)  

NASA Astrophysics Data System (ADS)

Although nearly all domain experts agree that human greenhouse gas emissions are altering the world's climate, a segment of the public rejects the scientific evidence. How can this gap between scientific knowledge and public understanding be bridged? Improved communication requires a better understanding of the cultural factors (e.g., political worldviews) and cognitive factors (e.g., inability to appreciate the concept of accumulation) that contribute to the public's rejection of the science. We review those factors and then provide practical guidance on more effective ways of communicating to the public. We focus on (a) framing of climate change in ways that are less challenging to people's worldview; (b) the role of the perceived scientific consensus in communication; and (c) ways in which uncertainty can be communicated without creating further barriers to acceptance of the science.

The effects of media violence on anxiety in late adolescence.  

PubMed

Exposure to media violence is related to anxiety in youth, but the causality of the effect has not been established. This experimental study examined the effects of media violence on anxiety, blood pressure, and heart rate in late adolescents. We also examined whether these responses varied by previous exposure to media and real-life violence. College students (N = 209; M age = 18.74; 75 % female; 50 % Caucasian, 34 % African American, 9 % Asian, 3 % Hispanic, and 3 % other racial minorities) were randomized to view either violent or nonviolent high-action movie clips. Participants reported on their anxiety before and after watching the clips, as well as their previous exposure to violence. Measures of blood pressure and heart rate were taken at baseline and during movie viewing. Participants watching violent movie clips showed a greater anxiety increase than those watching nonviolent clips. Both groups experienced increased blood pressure and reduced heart rate during movie watching compared to baseline. Prior exposure to media violence was associated with diminished heart rate response. Additionally, students previously exposed to high levels of real-life violence showed lower blood pressure increases when watching violent clips compared to nonviolent clips. Thus, relatively brief exposure to violent movie clips increased anxiety among late adolescents. Prior exposure to media and real-life violence were associated with lower physiological reactivity to high-action and violent movies, respectively, possibly indicating desensitization. Future studies should investigate long-term anxiety and physiological consequences of regular exposure to media violence in adolescence. PMID:24014349

Review of the effectiveness of video media in instruction  

NASA Astrophysics Data System (ADS)

Visual forms of instruction are increasingly used as a result of the widespread use of video technologies such as broadcasts, teleconferencing, tapes, videodiscs, and emerging multimedia combinations of computer and digital video technologies. The considerable amount of research that stretches back to early work with film, television, and static visual materials can be of benefit in developing these new forms of instruction. The objective is to present a review of the current research literature regarding the use of dynamic video media in instruction. Research on the following topics was reviewed: general reviews of the effectiveness, acceptance, and costs of several forms of educational television; teaching techniques used effectively with video media; combining visual and verbal information; the effects of motion, animation, and interactivity, the relationship between media perceptions and learning; the effect of various video production techniques on learning; and critical perspectives on learning from media. This review can be used as background material for future research or instructional development efforts concerned with learning from video-based media.

Media communication strategies for climate-friendly lifestyles - Addressing middle and lower class consumers for social-cultural change via Entertainment-Education  

NASA Astrophysics Data System (ADS)

This paper argues that Entertainment-Education (E-E) is a striking communication strategy for reaching middle and lower socio-economic classes with climate-friendly lifestyle messages. On the international level (e.g. in the US and the Netherlands) E-E approaches are being theoretically grounded, whereas in Germany they are not yet. Therefore further theoretical discussion and mapping of E-E approaches is central for future research. As a first step towards providing further theoretical foundations for E-E in the field of sustainability, the authors suggest a threefold mapping of E-E approaches. The threefold mapping of E-E approaches for communicating climate-friendly lifestyles to middle and lower class consumers is based on recent results from academic research and practical developments on the media market. The commonalities among the three is that they all promote pro-sustainability messages in an affective-orientated rather than cognitive-orientated, factual manner. Differences can be found in: the sender of the sustainability message, the targeted consumer groups and the media approach in use. Based on this, the paper draws the conclusion that two new paths for further research activities in the field of Entertainment-Education can be proposed: (1) Improving the existing approaches in practice by using theoretical foundation from the E-E field. This comprises at its core (A) to do formative, process and summative effect research on the messages and (B) to use E-E theory from the field of social psychology, sociology and communication science for further improvement and (2) Generating new E-E theories by analyzing the existing practical approaches in the media to communicate climate change.

The effect of gender and age differences on media selection in small and medium tourism enterprises.  

PubMed

The purpose of this study is to examine the impact that gender and age differences have on the communication media selection within the context of small and medium tourism enterprises (SMEs). Media Richness Theory (MRT) was used to assess media preferences in the firms. Using a mail questionnaire, data from 78 firms were collected on seven popular media in use. Historical data of the firms, media characteristics, and other firm-specific factors were included in the analysis. The results indicated that there are substantial gender and age differences in term of communication media selection. This is consistent with MRT and highlights the importance of choosing the appropriate media in SMEs, according with the employee's behaviors, in order to achieve better outcomes and to smooth the path towards good performance in the future.

Combining Social Media with Innovative Ways of Communicating about the James Webb Space Telescope  

NASA Astrophysics Data System (ADS)

In keeping with the cutting-edge nature of the James Webb Space Telescope, NASA is using a variety of social and interactive media to engage the public. While we do have a regularly updated static website, we are now also using various interactives (like Flash games and a 3D Tour of the spacecraft) to better explain what the Webb telescope is and how it works. To encourage future generations, we are a partner in an educational engineering design challenge which makes use of a virtual Second Life-like world. Additionally, the public can now watch Webb come together before their eyes by accessing our live webcam, which shows telescope hardware being built in our cleanroom. We are working to make Webb as much of a part of pop culture as the Hubble Space Telescope is. We facilitated the filming of a "Late Night with Jimmy Fallon” segment (called "Hubble Gotchu") featuring Webb and Webb scientists at NASA's Goddard Space Flight Center. A visit to the highly rated sitcom "The Big Bang Theory” resulted in Webb lithos, magnets, posters, a scale model, and more being regularly featured on the set of the show. The most important aspect to creating interesting ways to engage the public is having the ability to communicate and form relationships with as many people as possible. To that end, we are using tools like blogs (e.g., NASA Blueshift) and popular social media (Facebook, Twitter, YouTube, and Flickr) to reach out to as many people as we can and to enable them to share and spread the content we provide.

A Brief Survey of Media Access Control, Data Link Layer, and Protocol Technologies for Lunar Surface Communications  

NASA Technical Reports Server (NTRS)

This paper surveys and describes some of the existing media access control and data link layer technologies for possible application in lunar surface communications and the advanced wideband Direct Sequence Code Division Multiple Access (DSCDMA) conceptual systems utilizing phased-array technology that will evolve in the next decade. Time Domain Multiple Access (TDMA) and Code Division Multiple Access (CDMA) are standard Media Access Control (MAC) techniques that can be incorporated into lunar surface communications architectures. Another novel hybrid technique that is recently being developed for use with smart antenna technology combines the advantages of CDMA with those of TDMA. The relatively new and sundry wireless LAN data link layer protocols that are continually under development offer distinct advantages for lunar surface applications over the legacy protocols which are not wireless. Also several communication transport and routing protocols can be chosen with characteristics commensurate with smart antenna systems to provide spacecraft communications for links exhibiting high capacity on the surface of the Moon. The proper choices depend on the specific communication requirements.

Effect of media use on HIV-related stigma in Sub-Saharan Africa: a cross-sectional study.  

PubMed

It is known that HIV-related stigma hinders prevention efforts. Previous studies have documented that HIV-related stigma may be associated with socioeconomic and socioecological factors. Mass media use may moderate this association, but there is limited research addressing that possibility. In this study, based on cross-sectional data pooled from the 2006-2011 Demographic and Health Surveys of 11 sub-Saharan African countries (N?=?204,343), we investigated the moderating effects of exposure to mass media on HIV-related stigma. Hierarchical regression analysis indicated that HIV-related stigma tends to be higher among rural residents and individuals with low levels of education and HIV knowledge, as well as those who do not know people living with HIV. Media use was generally associated with low levels of HIV-related stigma, and attenuated the gap between individuals with high and low educational levels. However, the effect of mass media was found to be stronger among urbanites rather than among rural residents, which could lead to a widening gap between the two groups in endorsement of HIV-related stigma. The implication of this study regarding the effect of media use on HIV-related stigma in sub-Saharan Africa is twofold: 1) mass media may have the potential to minimize the gap in HIV-related stigma between individuals with high and low educational levels, and hence future efforts of reducing HIV-related stigma in the region may benefit from utilizing media; 2) due perhaps to low media penetration to rural sub-Saharan Africa, mass media could have the unintended effect of widening the urban-rural gap further unless other more customized and rural-focused communication interventions are put in place.

A quantative and qualitative analysis of science communication in the greek mass media  

NASA Astrophysics Data System (ADS)

During the last decade there has been increasing interest on how science is communicated by the mass media. Studies have been done in order to define the amount and the quality of science information passing from the experts to the public through newspapers, radio broadcasts and TV programs. In this study, we have tried to find the amount of science presented in 4 Greek newspapers and 4 major Greek TV channels. We've also done an initial evaluation on the quality of the newspaper science articles. The results show that the amount of scientific content in TV and newspapers in Greece, is comparable to those in larger and more scientifically advanced countries such as Canada, USA and Great Britain. The quality of the newspaper articles was studied under a simple but relevant coding scheme. The results demonstrate that scientists do not write popularizing articles but they play an important role as experts. The more serious newspapers provide more reliable information in the form of integrated articles and not as fragmentary science news. Furthermore, Greek newspapers avoid publishing articles on controversial scientific issues and they present science as abstract and authoritative.

Geosciences in an Immersive Fulldome Environment: Developing Science and Communication Skills by Creating Digital Media  

NASA Astrophysics Data System (ADS)

The Ho Tung Visualization Laboratory and Planetarium at Colgate University provides an opportunity for students of diverse backgrounds to learn scientific concepts and communication techniques through the creation of fulldome digital animations. Students give presentations to classes, school groups, and the public in the planetarium setting, and enhance learning by creating digital content appropriate to these audiences. The immersive environment is well-suited for showing large-scale geologic processes that may not be easily seen in the field. Geoscience projects include fly-bys of the Hudson River Valley, Cascade Mountain Range, Grand Canyon, and Basin and Range province, animation of the advance of the Laurentide Ice Sheet, evolution of continental positions since the late Precambrian, and comparisons of volcanic eruption styles. In order to create a digital animation, students must have a detailed understanding of the subject matter as well as all aspects of presentation, ranging from intended audience to relevant production technologies. This encourages students to explore material at a depth beyond conventional learning methods while integrating the skills necessary to effectively communicate scientific concepts to varied audiences. Based on these explorations, it appears beneficial to promote scientific visualization creation as a tool in itself to help students develop both scientific knowledge and communication skills.

Effects of therapists nonverbal communication on rated skill and effectiveness.  

PubMed

A therapist's nonverbal behavior may communicate emotion and feelings toward a client. Thus, skilled utilization of appropriate nonverbal cues should facilitate many nonbehavioral therapies. A 2 X 2 X 2 factorial experiment investigated the therapy-facilitating effects of three theoretical dimensions of nonverbal communication: Immediacy, potency or status, and responsivity. A reenacted client-centered therapy session was videotaped. Verbal content was held constant, but all combinations of the three nonverbal dimensions were portrayed. A total of 118 male and female nonparticipant observers rated the therapist's interpersonal skills (empathy, warmth, and genuineness) and effectiveness. The results disclosed that the nonverbal cues of immediacy (close therapist-client distance and eye contact) significantly improved ratings of the therapist's interpersonal skills and effectiveness. Thus, the study demonstrated that a therapist's nonverbal behavior is a basis for interpretations of empathy, warmth, genuiness, and effectiveness. These findings were interpreted in terms of the therapist's nonverbal cues communicating liking and acceptance of the client. PMID:7410567

However, there has been little empirical investigation of how information about neurobiological sex difference is interpreted within wider society. This paper presents a case study that tracks the journey of one high-profile study of neurobiological sex differences from its scientific publication through various layers of the public domain. A content analysis was performed to ascertain how the study was represented in five domains of communication: the original scientific article, a press release, the traditional news media, online reader comments and blog entries. Analysis suggested that scientific research on sex difference offers an opportunity to rehearse abiding cultural understandings of gender. In both scientific and popular contexts, traditional gender stereotypes were projected onto the novel scientific information, which was harnessed to demonstrate the factual truth and normative legitimacy of these beliefs. Though strains of misogyny were evident within the readers' comments, most discussion of the study took pains to portray the sexes' unique abilities as equal and 'complementary'. However, this content often resembled a form of benevolent sexism, in which praise of women's social-emotional skills compensated for their relegation from more esteemed trait-domains, such as rationality and productivity. The paper suggests that embedding these stereotype patterns in neuroscience may intensify their rhetorical potency by lending them the epistemic authority of science. It argues that the neuroscience of sex difference does not merely reflect, but can actively shape the gender norms of contemporary society. PMID:25354280

Training Scientists to be Effective Communicators: AAAS Communicating Science Workshops  

NASA Astrophysics Data System (ADS)

"Communicating Science: Tools for Scientists and Engineers" is a workshop program developed by AAAS to provide guidance and practice for scientists and engineers in communicating about science with public audiences. The program was launched at the 2008 AAAS Annual Meeting in Boston and has since provided 24 workshops for more than 1,500 scientist and engineer attendees at universities, science society meetings, and government agency labs around the United States. Each interactive workshop targets scientists and engineers specifically and has included content such as message development, defining audience, identifying opportunities for engaging the public, and practice with public presentations and cameras. The workshop format allows for collaborative learning through small-group discussion, resource sharing, and participation in critique of other participants' presentations. Continuous monitoring of the program includes on-site and online surveys and evaluation. On an assessment of workshops from 2008-2010, attendees reported that knowledge gained from the workshop helped in crafting messages about their scientific work for use in communicating with public audiences, and approximately 80 percent of respondents reported participation in communication with a public audience after attending the workshop. Through workshop content and feedback of participating scientists, this presentation will highlight some best practices and resources for scientists who want to take a proactive role in science communication.

Millimeter wave propagation modeling of inhomogeneous rain media for satellite communications systems  

NASA Technical Reports Server (NTRS)

A theoretical propagation model that represents the scattering properties of an inhomogeneous rain often found on a satellite communications link is presented. The model includes the scattering effects of an arbitrary distribution of particle type (rain or ice), particle shape, particle size, and particle orientation within a given rain cell. An associated rain propagation prediction program predicts attenuation, isolation and phase shift as a function of ground rain rate. A frequency independent synthetic storm algorithm is presented that models nonuniform rain rates present on a satellite link. Antenna effects are included along with a discussion of rain reciprocity. The model is verified using the latest available multiple frequency data from the CTS and COMSTAR satellites. The data covers a wide range of frequencies, elevation angles, and ground site locations.

Nanoscale optimization of quantum dot media for effective photovoltaic conversion  

NASA Astrophysics Data System (ADS)

Nanoscale engineering of band profile and potential profile provide effective tools for the management of photoelectron processes in quantum dot (QD) photovoltaic devices. We investigate the QD devices with various 1-?m InAs /GaAs QD media placed in a 3-?m base GaAs p-n junction. We found that n-charging of quantum dots (QDs) create potential barriers around QDs. QD growth between ultrathin AlGaAs layers leads to the formation of AlGaAs "fence" barriers, and reduces the wetting layers (WLs). The barriers around QDs and reduction of the wetting layer substantially suppress recombination processes via QDs. The n-doping of interdot space in QD media enhances electron extraction from QDs. All of our QD devices show short-circuit current, JSC, higher than that of the reference cell, but smaller open-circuit voltage, VOC.. In the QD devices, the short circuit currents increase by ~0.1 mA/cm2 per dot layer. JSC reaches 28.4 mA/cm2 in the device with QD media that combines dot charging, fence barriers, and WL reduction.

Adult Willingness to Use Email and Social Media for Peer-to-Peer Cancer Screening Communication: Quantitative Interview Study  

PubMed Central

Background Adults over age 40 are increasing their use of email and social media, raising interest in use of peer-to-peer Internet-based messaging to promote cancer screening. Objective The objective of our study was to assess current practices and attitudes toward use of email and other e-communication for peer-to-peer dialogues on cancer screening. Methods We conducted in-person interviews with 438 insured adults ages 42-73 in Georgia, Hawaii, and Massachusetts. Participants reported on use of email and other e-communication including social media to discuss with peers routine health topics including breast and colorectal cancer (CRC). We ascertained willingness to share personal CRC screening experiences via conversation, postcard, email, or other e-communication. Health literacy scores were measured. Results Email had been used by one-third (33.8%, 148/438) to discuss routine health topics, by 14.6% (64/438) to discuss breast cancer screening, and by 12.6% (55/438) to discuss CRC screening. Other e-communication was used to discuss routine health topics (11.6%, 51/438), screening for breast cancer (3.9%, 17/438), and CRC (2.3%, 10/438). In the preceding week, 84.5% (370/438) of participants had used email, 55.9% (245/438) had used e-communication of some type; 44.3% (194/438) text, 32.9% (144/438) Facebook, 12.3% (54/438) instant message, 7.1% (31/438) video chat, and 4.8% (21/438) Twitter. Many participants were willing to share their CRC screening experiences via email (32.4%, 142/438 might be willing; 36.3%, 159/438 very willing) and via other e-communication (15.8%, 69/438 might be willing; 14.4%, 63/438 very willing). Individuals willing to send CRC screening emails scored significantly higher on tests of health literacy compared to those willing to send only postcards (P<.001). Conclusions Many adults are willing to use email and e-communication to promote cancer screening to peers. Optimal approaches for encouraging peer-to-peer transmission of accurate and appropriate cancer screening messages must be studied. PMID:24287495

Communicating Genetics and Smoking Through Social Media: Are We There Yet?  

PubMed Central

Background Social media is a recent source of health information that could disseminate new scientific research, such as the genetics of smoking. Objective The objectives were (1) to evaluate the availability of genetic information about smoking on different social media platforms (ie, YouTube, Facebook, and Twitter) and (2) to assess the type and the content of the information displayed on the social media as well as the profile of people publishing this information. Methods We screened posts on YouTube, Facebook, and Twitter with the terms “smoking” and “genetic” at two time points (September 18, 2012, and May 7, 2013). The first 100 posts were reviewed for each media for the time points. Google was searched during Time 2 as an indicator of available information on the Web and the other social media that discussed genetics and smoking. The source of information, the country of the publisher, characteristics of the posts, and content of the posts were extracted. Results On YouTube, Facebook, and Twitter, 31, 0, and 84 posts, respectively, were included. Posts were mostly based on smoking-related diseases, referred to scientific publications, and were largely from the United States. From the Google search, most results were scientific databases. Six scientific publications referred to within the Google search were also retrieved on either YouTube or Twitter. Conclusions Despite the importance of public understanding of smoking and genetics, and the high use of social media, little information on this topic is actually present on social media. Therefore, there is a need to monitor the information that is there and to evaluate the population’s understanding of the information related to genetics and smoking that is displayed on social media.

This article describes different ways of communicating health education. Individual and group counseling are the most effective ways of changing people's behavior. It is a method by which, it could relieve anxieties, and offer better ways that explain information and help people make decisions on sexual and risk behavior subjects. Drawings, cartoons, visual aids and magazines could be of help in discussions. In the discussion of sensitive and embarrassing topics, it is much better for the use of traditional drama, storytelling, puppets etc. Leaflets and poster use are useful in the back up on counseling and health education programs. Establishing a health education regarding the struggle on AIDS takes time and effort, and it is best that counselors or educators are able to share their experiences and evaluate limited programs on this matter.

The Constitutive Relations and the Magnetoelectric Effect for Moving Media  

E-print Network

In this paper the constitutive relations for moving media with homogeneous and isotropic electric and magnetic properties are presented as the connections between the generalized magnetization-polarization bivector $%\\mathcal{M}$ and the electromagnetic field F. Using the decompositions of F and $\\mathcal{M}$, it is shown how the polarization vector P(x) and the magnetization vector M(x) depend on E, B and two different velocity vectors, u - the bulk velocity vector of the medium, and v - the velocity vector of the observers who measure E and B fields. These constitutive relations with four-dimensional geometric quantities, which correctly transform under the Lorentz transformations (LT), are compared with Minkowski's constitutive relations with the 3-vectors and several essential differences are pointed out. They are caused by the fact that, contrary to the general opinion, the usual transformations of the 3-vectors $% \\mathbf{E}$, $\\mathbf{B}$, $\\mathbf{P}$, $\\mathbf{M}$, etc. are not the LT. The physical explanation is presented for the existence of the magnetoelectric effect in moving media that essentially differs from the traditional one.

Effect of Apolactoferrin on Experimental Pneumococcal Otitis Media  

PubMed Central

Objective To find the effect of apolactoferrin administration on the middle and inner ears after experimentally induced pneumococcal otitis media. Design Histopathologic and morphometric analysis of the middle and inner ears. Setting University of Minnesota, Minneapolis. Subjects Ten chinchillas. Interventions The middle ear cavities of chinchillas were inoculated bilaterally with type 2 wild-type Streptococcus pneumoniae. Twenty-four hours later, the ears of 5 of the animals were injected with phosphate-buffered saline (PBS) and the other 5 with human apolactoferrin. The animals were killed 24 hours after the last injection. Bacterial counts were made of the middle ear effusions, and the cochleae were processed for histologic analysis. The thickness of the round window membranes and bacterial and inflammatory cell infiltration of the round window membranes, and scala tympani and damage of the hair cells and stria vascularis were compared for these 2 groups of animals. Main Outcome Measures Comparison of inflammatory and bacterial cells in the middle and inner ears, and damage to inner ear structures. Results Bacterial plate counts of middle ear effusions (P = .005) and the number of inflammatory cells in the round window membrane (P = .047) were significantly lower in the apolactoferrin group compared with the group treated with PBS. Conclusion Further investigation of apolactoferrin as a nonantibiotic approach for the treatment of otitis media and its complications is needed to confirm its safety and efficacy. PMID:21079169

Capillary effect in salt-cemented media of particle sizes  

NASA Astrophysics Data System (ADS)

Natural cementation such as salt cementation may significantly affect the geotechnical properties of soils at low confining pressures. Capillary force plays a key role in the distribution patterns of salt cementation resulting from dehydration. The aim of this study is to investigate the effect of capillary force on salt cementation through cone penetration testing, electrical conductivity measurements, photographic imaging technique, and nondestructive elastic wave scanning. Granular media is modeled using glass beads which are saturated in salt water and cemented by oven drying. The cone tip resistance profiles, electrical conductivity profiles, and amplitudes of the scanned elastic waves are high at the top of the specimen with small-sized particles, in the middle of the specimen in medium-sized particles, and at the bottom of the specimen in the large-sized particles. Differences in the distribution of salt in the cemented specimens are confirmed from photographic images. The calculated capillary heights are associated with the areas of high salt concentration in the cemented specimens. The four investigation methods used in this study show that the behavior of salt-cemented granular media depends on capillary force in a shallow depth.

Examining the effects of mass media campaign exposure and interpersonal discussions on youth's drug use: the mediating role of visiting pro-drug websites.  

PubMed

To extend past research on interpersonal communication and campaign effects, we hypothesized that anti-drug mass media campaign message exposure indirectly affects visiting anti- and pro-drug websites through targeted parent-child and friend-to-friend communication against drugs, as well as through having drug-related discussions during organized group activities. Second, we posited that engaging in anti-drug interpersonal communication indirectly affects adolescents' drug use through two intervening variables: visiting anti-drug websites and visiting pro-drug websites. Using self-reported longitudinal data from 2,749 youth, we found that as youth reported higher levels of anti-drug mass media campaign message exposure, they were more likely to talk to friends about the bad consequences of drugs, how to avoid drugs, and anti-drug ads. In turn, however, they were more likely to visit pro-drug websites, and subsequently, to smoke cigarettes. PMID:22816432

Clinical Communication failures are considered the leading cause of medical errors [1]. Minimizing communication problems among clinical team members could directly reduce medical errors and hence, increase patient safety and improve health care quality. Our main focus is, through knowledge representation approach, to develop an understanding of communication problems applied to health care settings. This will serve as the foundation to our long term goal of building an ontology-driven educational tool that will be used to educate clinicians about miscommunication issues and as a means to improve it.

How effective and cost-effective was the national mass media smoking cessation campaign ‘Stoptober’??  

PubMed Central

Background A national smoking cessation campaign based on behaviour change theory and operating through both traditional and new media was launched across England during late 2012 (‘Stoptober’). In addition to attempting to start a movement in which smokers would quit at the same time in response to a positive mass quitting trigger, the campaign set smokers the goal of being smoke-free for October and embodied other psychological principles in a range of tools and communications. Methods Data on quit attempts were obtained from 31,566 past-year smokers during nationally representative household surveys conducted monthly between 2007 and 2012. The effectiveness of the campaign was assessed by the increase in national quit attempt rate in October relative to other months in 2012 vs. 2007–2011. Results Relative to other months in the year, more people tried to quit in October in 2012 compared with 2007–2011 (OR = 1.79, 95%CI = 1.20–2.68). In 2012 there was an approximately 50% increase in quitting during October compared with other months of the same year (9.6% vs. 6.6%; OR = 1.50, 95%CI = 1.05–2.15), whereas in 2007–2011 the rate in October was non-significantly less than in other months of the same period (6.4% vs. 7.5%; OR = 0.84, 95%CI = 0.70–1.00). Stoptober is estimated to have generated an additional 350,000 quit attempts and saved 10,400 discounted life years (DLY) at less than £415 per DLY in the modal age group. Conclusions Designing a national public health campaign with a clear behavioural target (making a serious quit attempt) using key psychological principles can yield substantial behaviour change and public health impact.

Are pharmaceutical marketing decisions calibrated to communications effects?  

PubMed

Marketing managers continually struggle with how to maximize the effects of an integrated marketing communications strategy. The growing number of available communication outlets, as well as highly varying competitive landscapes, adds further complexity to this challenge. This empirical study examines the differential impact within a pharmaceutical market therapeutic category where both "push" and "pull" communication strategies operate on consumers and gatekeepers alike, in an atmosphere of unrelenting product innovation and broad competition. Furthermore, we explore how two contingency variables-(a) the competitive landscape, and (b) the product's length of time on the market-interact with these communication efforts and affect brand and category sales.

Effectiveness of interventions that apply new media to improve vaccine uptake and vaccine coverage.  

PubMed

Background Vaccine-preventable diseases (VPD) are still a major cause of morbidity and mortality worldwide. In high and middle-income settings, immunization coverage is relatively high. However, in many countries coverage rates of routinely recommended vaccines are still below the targets established by international and national advisory committees. Progress in the field of communication technology might provide useful tools to enhance immunization strategies. Objective To systematically collect and summarize the available evidence on the effectiveness of interventions that apply new media to promote vaccination uptake and increase vaccination coverage. Design We conducted a systematic literature review. Studies published from January 1999 to September 2013 were identified by searching electronic resources (Pubmed, Embase), manual searches of references and expert consultation. Study setting We focused on interventions that targeted recommended vaccinations for children, adolescents and adults and: (1) aimed at increasing community demand for immunizations, or (2) were provider-based interventions. We limited the study setting to countries that are members of the Organisation for Economic Co-operation and Development (OECD). Main outcome measures The primary outcome was a measure of vaccination (vaccine uptake or vaccine coverage). Considered secondary outcomes included willingness to receive immunization, attitudes and perceptions toward vaccination, and perceived helpfulness of the intervention. Results Nineteen studies were included in the systematic review. The majority of the studies were conducted in the US (74%, n = 14); 68% (n = 13) of the studies were experimental, the rest having an observational study design. Eleven (58%) reported results on the primary outcome. Retrieved studies explored the role of: text messaging (n.7, 37%), smartphone applications (n.1, 5%), Youtube videos (n.1, 5%), Facebook (n.1, 5%), targeted websites and portals (n.4, 21%), software for physicians and health professionals (n.4, 21%), and email communication (n.1, 5%). There is some evidence that text messaging, accessing immunization campaign websites, using patient-held web-based portals and computerized reminders increase immunization coverage rates. Insufficient evidence is available on the use of social networks, email communication and smartphone applications. Conclusion Although there is great potential for improving vaccine uptake and vaccine coverage by implementing programs and interventions that apply new media, scant data are available and further rigorous research - including cost-effectiveness assessments - is needed.

The effectiveness of mass communication to change public behavior.  

PubMed

This article provides an overview of the ways in which mass communication has been used -- or can be used -- to promote beneficial changes in behavior among members of populations. We use an ecological perspective to examine the ways in which mass media interventions can be used to influence public behavior both directly and indirectly. Mass media interventions that seek to influence people directly -- by directly targeting the people burdened by the public health problem of concern and/or the people who influence them -- have a long basis in public health history, and recent reviews have clarified our expectations about what can be expected from such approaches. Mass media interventions that seek to influence people indirectly -- by creating beneficial changes in the places (or environments) in which people live and work -- have equal if not greater potential to promote beneficial changes in population health behaviors, but these are currently less explored options. To have the greatest possible beneficial influence on public behavior with the public health resources available, we recommend that public health program planners assess their opportunities to use media to target both people and places in a manner that complements and extends other investments being made in population health enhancement.

Effects of a brief school-based media literacy intervention on digital media use in adolescents: cluster randomized controlled trial.  

PubMed

The aim of this study was to evaluate the effects of a four-session school-based media literacy curriculum on adolescent computer gaming and Internet use behavior. The study comprised a cluster randomized controlled trial with three assessments (baseline, posttest, and 12-month follow-up). At baseline, a total of 2,303 sixth and seventh grade adolescents from 27 secondary schools were assessed. Of these, 1,843 (80%) could be reached at all three assessments (Mage=12.0 years; SD=0.83). Students of the intervention group received the media literacy program Vernetzte www.Welten ("Connected www.Worlds ") implemented by trained teachers during class time. The control group attended regular class. Main outcome measures were adolescents' computer gaming and Internet use: days per month, hours per day, and addictive use patterns. Parental media monitoring and rules at home were assessed as secondary outcomes. Results of multilevel growth-curve models revealed a significant intervention effect in terms of a lower increase in self-reported gaming frequency (??= -1.10 [95% CI -2.06, -0.13]), gaming time (??= -0.27 [95% CI -0.40, -0.14]), and proportion of excessive gamers (AOR=0.21 [95% CI 0.08, 0.57]) in the intervention group. There were also significant group-time interactions for the addictive gaming scale (?=-0.08 [95% CI -0.12, -0.04]), and the Internet Addiction Scale (??= -0.06 [95% CI -0.10, -0.01]). No effect was found for days and hours of Internet use or parental media behavior. The study shows that the program Vernetzte www.Welten can influence adolescents' media use behavior. Future research should address mediating and moderating variables of program effects. PMID:25126888

Ethical media competence as a protective factor against cyberbullying and cybervictimization among german school students.  

PubMed

The use of digital information and communication technologies is an integral part of adolescents' everyday life. Besides various opportunities for information, entertainment, and communication, media use is associated with risks such as cyberbullying. Cyberbullying refers to aggressive behavior in the context of computer-mediated communication, characterized by repetition, an intention to harm, and power imbalance. Previous studies have shown that increased media use is a major risk factor for cyberbullying and cybervictimization. Given that restricting media use is not a practical way to reduce the negative effects inherent in media use, the present study examines the relevance of ethical media competence. We expected ethical media competence to buffer the effect of increased media use on cyberbullying and cybervictimization. A survey was conducted with 934 students (53% female) aged 10-17 years (M=13.26, SD=1.63). As expected, hierarchical regression analyses showed a positive main effect of media use, a negative main effect of ethical media competence, and a negative interaction effect of media use and media competence on cyberbullying and cybervictimization. Simple slope analyses revealed that at high levels of ethical media competence, media use has almost no effect on cybervictimization and a significant negative effect on cyberbullying. Consequently, promoting ethical media competence constitutes a potential measure to prevent the risks of increased media use for cyberbullying and cybervictimization. PMID:25272238

The impact of mass media health communication on health decision-making and medical advice-seeking behavior of u.s. Hispanic population.  

PubMed

Mass media health communication has enormous potential to drastically alter how health-related information is disseminated and obtained by different populations. However, there is little evidence regarding the influence of media channels on health decision-making and medical advice-seeking behaviors among the Hispanic population. The Pew 2007 Hispanic Healthcare Survey was used to test the hypothesis that the amount of mass media health communication (i.e., quantity of media-based health information received) is more likely to influence Hispanic adults' health decision-making and medical advice-seeking behavior compared to health literacy and language proficiency variables. Results indicated that quantity of media-based health information is positively associated with health decision-making and medical advice-seeking behavior above and beyond the influence of health literacy and English and Spanish language proficiency. In a context where physician-patient dynamics are increasingly shifting from a passive patient role model to a more active patient role model, media-based health information can serve as an influential cue to action, prompting Hispanic individuals to make certain health-related decisions and to seek more health advice and information from a health provider. Study implications are discussed. PMID:22888787

Is Public Communication about End-of-Life Care Helping to Inform All?: Cancer News Coverage in African American vs. Mainstream Media  

PubMed Central

Background Because cancers are a leading cause of death, these diseases receive a great deal of news attention. However, because news media frequently target specific racial or ethnic audiences, some populations may receive different information, and it is unknown whether reporting equally informs all about options for care at the end of life. This study of US news reporting compares “mainstream” (general market) media to African American media, which serves the largest minority group. The specific goal of this study was to determine whether these news media communicate differently about cure-directed cancer treatment and end-of-life alternatives. Methods This content analysis includes 660 cancer news stories from online and print media that target either African American or mainstream audiences. The main outcome measures include whether reporting discussed: adverse events of cancer treatment; cancer treatment failure; cancer death/dying; and end-of-life palliative or hospice care. Results Unadjusted and adjusted analyses indicate that the news stories in the African American media are less likely than those in mainstream media to discuss each of the topics studied. Comparing the proportions of news stories in mainstream vs. African American media , 31.6% vs. 13.6% discussed adverse events (OR 2.92; 95% CI 1.51-5.66; P=0.001); 14.1% vs. 4.2% mentioned treatment failure (OR, 3.79; 95% CI 1.45-9.88; P=0.006); and 11.9% vs. 3.8% focused on death/dying (OR, 3.42; 95% CI 1.39-8.38; P=.007). Lastly, although very few news stories discussed end-of-life hospice or palliative care, all were found in mainstream media (7/396 vs. 0/264). Conclusion The African American news media sampled are less likely than mainstream news media to portray negative cancer outcomes and end-of-life care. Given media's segmented audiences, these findings raise concerns that not all audiences are being informed equally well. Because media content is modifiable, there may be opportunities to improve public cancer communication. PMID:21952922

Is news media related to civic engagement? The effects of interest in and discussions about the news media on current and future civic engagement of adolescents.  

PubMed

This study explored whether discussions about the media, when positively linked to interest in the news media, were related to adolescents' current and future civic engagement. A sample of 2638 adolescents (age M = 17, SD = 1.2), who participated in a school-based study on positive socialization, completed self-report measures on interest in the news media and discussions about the media with parents and friends. Current civic engagement was measured by involvement in volunteering and civic commitments. Future civic engagement was measured by intentions to participate in civic activities in the future. The results showed that more interpersonal discussions about the media and higher interest in the news media both predicted higher civic engagement. Positive links between discussions about the media and current civic engagement were partly mediated by interest in the news media. In addition, interest in the news media together with current civic engagement fully mediated a positive link between discussions about the media and future civic engagement. Moderating effects of gender were observed, with discussions about the media a better predictor of boys' interest in the news media, and current civic engagement a better predictor of girls' future civic engagement.

Ocean environmental effects on walrus communication  

NASA Astrophysics Data System (ADS)

This work aimed to develop source characteristics and transmission effects for the acoustic breeding displays of male Pacific walrus (Odobenus rosmarus divergens). Pacific walrus breeding activities occur in late winter in the Bering Sea, an area renowned for extreme weather conditions and high biological productivity. During the breeding season, males perform acoustic displays while swimming in the vicinity of females hauled out on ice. Underwater vocalizations heard by individuals hauled out on ice may be important in the mate selection process. The extreme environment in which walrus breeding activities occur precludes direct observation of these animals during this important period and has resulted in a lack of data. A combination of remote-sensing data, captive animal research, controlled environment experiment, and computational modeling was used to increase our understanding of the acoustic displays of Pacific walrus. Analysis of recordings of captive and wild male Pacific walrus vocalizations during breeding season provided quantification of source characteristics. Working with a captive animal provided the ability to make direct observations of a male producing breeding vocalizations and the direct calculation of source level. The mean peak to peak source level of the impulsive knocks produced by the captive male was 183 dB (re: 1 microPa) with the middle 95% of the knocks between 168 dB and 195 dB. The broadband knock signals contained significant acoustic energy up to 13 kHz. To estimate source level from wild vocalizations, the location of the source walrus first needed to be determined. Using a method of relative multipath arrival time, more than 37,000 knocks were localized from six years of data from autonomous recorders deployed in the Bering Sea. The mean peak-peak source level from the wild recordings was 177 dB (re: 1 microPa) with 95% of the knocks between 163 dB and 189 dB. For both wild and captive vocalizations, a significant relationship between ambient noise level and source level was identified. The Lombard effect, the increase in source level in response to an increase in noise level has not previously been identified in any pinniped species. In both datasets, an increase of approximately 5 dB in source level was found for an increase in 10 dB of noise level. A propagation experiment was conducted to measure the transmission of an impulsive acoustic signal, similar to a walrus knock, from an underwater source through ice and into air. Peak to peak pressure measured in air was approximately 2,500 times lower than pressure measured in water separated by two meters of shorefast ice. The results from this experiment were used to verify the adequacy of a wavenumber integration acoustic propagation model for determining transmission loss in this multi-media environment. Propagation model environments were generated from historical ice thickness and oceanographic data. Modeled received signals were compared with walrus audiometric data to determine what factors impact signal detectability with source level, ice thickness, and range having the greatest impact. The findings of this work suggest that the underwater vocalizations of males making breeding vocalizations are received by females hauled out on ice at audible levels when the females are within a few hundred meters of the males. As the signals exceed the levels estimated to be perceived, these signals may play a role in mate selection by the females. If climate change affects the ice conditions, water depth, and bathymetry where walrus congregate for breeding, mate selection and therefore offspring fitness may be impacted.

Passing crisis and emergency risk communications: The effects of communication channel, information type, and repetition.  

PubMed

Three experiments explore several factors which influence information transmission when warning messages are passed from person to person. In Experiment 1, messages were passed down chains of participants using five different modes of communication. Written communication channels resulted in more accurate message transmission than verbal. In addition, some elements of the message endured further down the chain than others. Experiment 2 largely replicated these effects and also demonstrated that simple repetition of a message eliminated differences between written and spoken communication. In a final field experiment, chains of participants passed information however they wanted to, with the proviso that half of the chains could not use telephones. Here, the lack of ability to use a telephone did not affect accuracy, but did slow down the speed of transmission from the recipient of the message to the last person in the chain. Implications of the findings for crisis and emergency risk communication are discussed. PMID:25683552

Social Media and the Social Good: How Nonprofits Use Facebook to Communicate with the Public  

E-print Network

In this study, we examine the social networking practices of the 100 largest nonprofit organizations in the United States. More specifically, we develop a comprehensive classification scheme to delineate these organizations' use of Facebook as a stakeholder engagement tool. We find that there are 5 primary categories of Facebook "statuses", which can be aggregated into three key dimensions - "information", "community", and "action". Our analysis reveals that, though the "informational" use of Facebook is still significant, nonprofit organizations are better at using Facebook to strategically engage their stakeholders via "dialogic" and "community-building" practices than they have been with traditional websites. The adoption of social media seems to have engendered new paradigms of public engagement.

Media as social influence: racial differences in the effects of peers and media on adolescent alcohol cognitions and consumption.  

PubMed

Racial differences in the effects of peer and media influence on adolescents' alcohol cognitions and consumption were examined in a large-scale panel study. With regard to peer influence, results from cross-lagged panel analyses indicated that the relation between perceived peer drinking and own drinking was significant for both Black and White adolescents, but it was stronger for the White adolescents. With regard to media influence, structural modeling analyses indicated that exposure to drinking in movies was associated with more alcohol consumption 8 months and 16 months later. These effects were mediated by increases in the favorability of the adolescents' drinker prototypes, their willingness to drink, and their tendency to affiliate with friends who were drinking. Multiple group analyses indicated that, once again, the effects (both direct and indirect) were much stronger for White adolescents than for Black adolescents. The results suggest media influence works in a similar manner to social influence and that Whites may be more susceptible to both types of influence. PMID:21198226

Effective physician-patient communication and health outcomes: a review.  

PubMed Central

OBJECTIVE: To ascertain whether the quality of physician-patient communication makes a significant difference to patient health outcomes. DATA SOURCES: The MEDLINE database was searched for articles published from 1983 to 1993 using "physician-patient relations" as the primary medical subject heading. Several bibliographies and conference proceedings were also reviewed. STUDY SELECTION: Randomized controlled trials (RCTs) and analytic studies of physician-patient communication in which patient health was an outcome variable. DATA EXTRACTION: The following information was recorded about each study: sample size, patient characteristics, clinical setting, elements of communication assessed, patient outcomes measured, and direction and significance of any association found between aspects of communication and patient outcomes. DATA SYNTHESIS: Of the 21 studies that met the final criteria for review, 16 reported positive results, 4 reported negative (i.e., nonsignificant) results, and 1 was inconclusive. The quality of communication both in the history-taking segment of the visit and during discussion of the management plan was found to influence patient health outcomes. The outcomes affected were, in descending order of frequency, emotional health, symptom resolution, function, physiologic measures (i.e., blood pressure and blood sugar level) and pain control. CONCLUSIONS: Most of the studies reviewed demonstrated a correlation between effective physician-patient communication and improved patient health outcomes. The components of effective communication identified by these studies can be used as the basis both for curriculum development in medical education and for patient education programs. Future research should focus on evaluating such educational programs. PMID:7728691

[The paradoxical effect of persuasive communication in health education sessions].  

PubMed

The purpose of this study was to examine the communication dynamics leading to the adoption of new attitudes and cognitions in health education sessions. We examined the verbal interactions at work in persuasive communication in 16 health education sessions. The study found that the medical expertise of the educator and the initial level of commitment of the participants had a positive effect on adherence to recommendations. However, persuasive communication in health education sessions appears to involve a paradoxical process in which criticism of the message can go hand in hand with the expression of an intention to implement new risk-reducing behaviors.

Performance effects of irregular communications patterns on massively parallel multiprocessors  

NASA Technical Reports Server (NTRS)

A detailed study of the performance effects of irregular communications patterns on the CM-2 was conducted. The communications capabilities of the CM-2 were characterized under a variety of controlled conditions. In the process of carrying out the performance evaluation, extensive use was made of a parameterized synthetic mesh. In addition, timings with unstructured meshes generated for aerodynamic codes and a set of sparse matrices with banded patterns on non-zeroes were performed. This benchmarking suite stresses the communications capabilities of the CM-2 in a range of different ways. Benchmark results demonstrate that it is possible to make effective use of much of the massive concurrency available in the communications network.

Effect of media use on HIV/AIDS-related knowledge and condom use in sub-Saharan Africa: a cross-sectional study.  

PubMed

It is known that the level of HIV/AIDS-related knowledge and the degree of condom use varies by socioeconomic status (SES). However, there is limited research on the effect of mass media use on HIV/AIDS-related cognitive and behavioral outcomes in low-income countries and how it might influence the association between SES and HIV-related outcomes. We investigated the moderating effect of media use on the relationship between SES and HIV/AIDS-related knowledge and condom use in sub-Saharan Africa in terms of communication inequalities. Cross-sectional data from the Demographic Health Surveys from 13 sub-Saharan countries (2004-10) were pooled. Gender-stratified multivariable poisson regression of 151,209 women and 68,890 men were used to calculate adjusted relative ratios and 95% confidence intervals for the associations between SES, media use, HIV-related outcomes, and condom use. We found significant disparities in mass media use among people from different SES groups as well as among countries. Education and wealth are strongly and positively associated with awareness of HIV/AIDS and knowledge about transmission and prevention of HIV/AIDS and are significantly associated with condom use. These associations are attenuated when the use of various types of mass media is added to the models, with newspapers showing the strongest effect. The findings of this study suggest that media use has the potential to blunt the impact of socioeconomic status though not completely eliminate it. Thus, we need to pay attention to reducing communication inequalities among social groups and countries to moderate the effect of wealth and SES on HIV/AIDS. PMID:23874598

Acetobacter aceti MTCC 2623 was studied as an alternative microbial source for bacterial cellulose (BC) production. Effect of media components on cell growth rate, BC production and cellulose characteristics were studied. FTIR results showed significant variations in cellulose characteristics produced by A. aceti in different media. Results have shown the role of fermentation time on crystallinity ratio of BC in different media. Further, effect of six different media components on cell growth and BC production was studied using fractional factorial design. Citric acid was found to be the most significant media component for cell growth rate (95% confidence level, R(2)=0.95). However, direct role of these parameters on cellulose production was not established (p-value>0.05). PMID:23544503

The effectiveness of different approaches to media literacy in modifying adolescents' responses to alcohol.  

PubMed

Fearing the negative effect that alcohol advertising might have on adolescents' receptiveness to the consumption of alcohol, health educators have used media literacy as an effective strategy to mitigate the effect of these messages in the media. The present study applied parental mediation to the design and evaluations of a media literacy curriculum that targets alcohol decision-making processes illustrated in the message interpretation process model. The authors conducted a pretest-posttest quasi-experiment of 171 adolescents to examine the effect of a negative evaluative approach and a balanced evaluative approach (a combination of negative and positive evaluative strategies) to media literacy on modifying adolescents' responses to alcohol messages. Results showed that different media literacy approaches had varying degrees of effectiveness on adolescent boys and girls. After receiving a negative media literacy lesson, adolescent boys regarded television characters as less realistic and believed that drinking alcohol had negative consequences. In contrast, adolescent girls benefited more from a balanced evaluative approach as their media skepticism attitude was enhanced. Results suggest that health educators should choose tailored pedagogical approaches that are based on gender to improve decision making regarding alcohol consumption. PMID:23496333

Quantifying Effective Flow and Transport Properties in Heterogeneous Porous Media  

NASA Astrophysics Data System (ADS)

Spatial heterogeneity, the spatial variation in physical and chemical properties, exists at almost all scales and is an intrinsic property of natural porous media. It is important to understand and quantify how small-scale spatial variations determine large-scale "effective" properties in order to predict fluid flow and transport behavior in the natural subsurface. In this work, we aim to systematically understand and quantify the role of the spatial distribution of sand grains of different sizes in determining effective dispersivity and effective permeability using quasi-2D flow-cell experiments and numerical simulations. Two dimensional flow cells (20 cm by 20 cm) were packed with the same total amount of fine and coarse sands however with different spatial patterns. The homogeneous case has the completely mixed fine and coarse sands. The four zone case distributes the fine sand in four identical square zones within the coarse sand matrix. The one square case has all the fine sands in one square block. With the one square case pattern, two more experiments were designed in order to examine the effect of grain size contrast on effective permeability and dispersivity. Effective permeability was calculated based on both experimental and modeling results. Tracer tests were run for all cases. Advection dispersion equations were solved to match breakthrough data and to obtain average dispersivity. We also used Continuous Time Random Walk (CTRW) to quantify the non-Fickian transport behavior for each case. For the three cases with the same grain size contrast, the results show that the effective permeability does not differ significantly. The effective dispersion coefficient is the smallest for the homogeneous case (0.05 cm) and largest for the four zone case (0.27 cm). With the same pattern, the dispersivity value is the largest with the highest size contrast (0.28 cm), which is higher than the one with the lowest case by a factor of 2. The non-Fickian behavior was quantified by the ? value within the CTRW framework. Fickian transport will result in ? values larger than 2 while its deviation from 2 indicates the extent of non-Fickian behavior. Among the three cases with the same grain size contrast, the ? value is closest to 2 in the homogeneous case (1.95), while smallest in the four zone case (1.89). In the one square case, with the highest size contrast, the ? value was 1.57, indicating increasing extent of non-Fickian behavior with higher size contrast. This study is one step toward understanding how small-scale spatial variation in physical properties affect large-scale flow and transport behavior. This step is important in predicting subsurface transport processes that are relevant to earth sciences, environmental engineering, and petroleum engineering.

The communication triangle: elements of an effective warning message  

SciTech Connect

The lack of good communication is a very real problem in mine emergencies. To counter communication breakdowns, researchers at the NIOSH Pittsburgh Research Laboratory developed the Emergency Communication Triangle. It is a training intervention designed to help those giving a warning to provide the right sort of information and those receiving a warning to ask the right questions. The Triangle has six ordered components with the first three considered most important. The Emergency Communication is packaged as a short safety talk to be given by supervisors at the start of a shift. It was first tested in 1998 with a group of 236 workers at an underground mine in Colorado, and proved effective. It was followed up in 2003 and again in 2004. Now, more than half the miners would report who was affected by an event, 60% would report in its severity, and 70% would say what had been done so far. 3 figs.

Effective Nurse Communication With Type 2 Diabetes Patients: A Review.  

PubMed

Many type 2 diabetes mellitus patients have difficulties reaching optimal blood glucose control. With patients treated in primary care by nurses, nurse communication plays a pivotal role in supporting patient health. The twofold aim of the present review is to categorize common barriers to nurse-patient communication and to review potentially effective communication methods. Important communication barriers are lack of skills and self-efficacy, possibly because nurses work in a context where they have to perform biomedical examinations and then perform patient-centered counseling from a biopsychosocial approach. Training in patient-centered counseling does not seem helpful in overcoming this paradox. Rather, patient-centeredness should be regarded as a basic condition for counseling, whereby nurses and patients seek to cooperate and share responsibility based on trust. Nurses may be more successful when incorporating behavior change counseling based on psychological principles of self-regulation, for example, goal setting, incremental performance accomplishments, and action planning.

The Effect on Wireless Sensor Communication When Deployed in Biomass  

PubMed Central

Wireless sensor networks (WSN) have been studied in a variety of scenarios over recent years, but work has almost exclusively been done using air as the transmission media. In this article some of the challenges of deploying a WSN in a heterogeneous biomass, in this case silage, is handled. The dielectric constant of silage is measured using an open-ended coaxial probe. Results were successfully obtained in the frequency range from 400 MHz to 4 GHz, but large variations suggested that a larger probe should be used for more stable results. Furthermore, the detuning of helix and loop antennas and the transmission loss of the two types of antennas embedded in silage was measured. It was found that the loop antenna suffered less from detuning but was worse when transmitting. Lastly, it is suggested that taking the dielectric properties of silage into account during hardware development could result in much better achievable communication range. PMID:22164076

Intercultural communication between patients and health care providers: an exploration of intercultural communication effectiveness, cultural sensitivity, stress, and anxiety.  

PubMed

Cultural diversity is becoming increasingly more important in the workplace. This is particularly true in health care organizations facing demographic shifts in the patients served and their families. This study serves to aid the development of intercultural communication training programs for health care providers by examining how cultural sensitivity and effective intercultural communication, besides helping patients, personally benefit health care providers by reducing their stress. Effective intercultural communication and cultural sensitivity were found to be related. Health care providers' levels of intercultural anxiety also were found to correlate with effective intercultural communication. PMID:11771806

Harnessing social media for health promotion and behavior change.  

PubMed

Rapid and innovative advances in participative Internet communications, referred to as "social media," offer opportunities for modifying health behavior. Social media let users choose to be either anonymous or identified. People of all demographics are adopting these technologies whether on their computers or through mobile devices, and they are increasingly using these social media for health-related issues. Although social media have considerable potential as tools for health promotion and education, these media, like traditional health promotion media, require careful application and may not always achieve their desired outcomes. This article summarizes current evidence and understanding of using social media for health promotion. More important, it discusses the need for evaluating the effectiveness of various forms of social media and incorporating outcomes research and theory in the design of health promotion programs for social media.

Information and Communication Technology  

NSDL National Science Digital Library

Communication is a central aspect of all our lives. Today, our modes of communication are highly dependent on technologies such as the internet, wireless networks, phones, and computers. This issue of Topic in Depth explores the ways these forms of communication are part of our lives and highlights some new directions in communication technology.WordIQ Dictionary and Encyclopedia (1) offers this definition: "Communication is the process of exchanging information usually via a common system of symbols." The website explains some of the key process involved in communication and describes different forms of communication, such as animal communication, interpersonal communication, and computer-mediated communication. Also taking a broad view on communication, this world history website (2) provides some background on the mathematical theories that are used in designing telecommunications systems. The articles highlighted on this website from the Center for the Study of Technology and Society (4) attest to the far reaching influence of communication technology. As research on the MediaLab Europe website suggests (5), we have moved into not just developing technology that mediates interpersonal communication (such as phones) but also creating "intimate and personal connections with and through new technologies." This NSF website (6) also highlights some recent discoveries in Computer Information Science and Engineering. Finally, this article from First Monday (7) discusses the far-reaching effects these new developments in technology and globalization are having on language and learning.

Comfortably numb: desensitizing effects of violent media on helping others.  

PubMed

Two studies tested the hypothesis that exposure to violent media reduces aid offered to people in pain. In Study 1, participants played a violent or nonviolent video game for 20 min. After game play, while completing a lengthy questionnaire, they heard a loud fight, in which one person was injured, outside the lab. Participants who played violent games took longer to help the injured victim, rated the fight as less serious, and were less likely to "hear" the fight in comparison to participants who played nonviolent games. In Study 2, violent- and nonviolent-movie attendees witnessed a young woman with an injured ankle struggle to pick up her crutches outside the theater either before or after the movie. Participants who had just watched a violent movie took longer to help than participants in the other three conditions. The findings from both studies suggest that violent media make people numb to the pain and suffering of others. PMID:19207695

Investigation of the effects of polyelectrolyte coatings on colloid transport in porous media  

SciTech Connect

Goal is to study the repulsive interaction forces between humic- coated colloids and negatively charged porous media surfaces. Filtration experiments were carried out on hematite coated with humic acid or NOM, in porous media or packed bed (silica bed). Effects of Ca[sup 2+] are being studied. Results so far indicate that many humic coating properties (molecular size, acidity, polarity, surface conformation) have an important effect on colloid attachment rates but very little effect on colloid electrophoretic mobility; steric repulsive forces are proposed to account for these observations. Some humic coatings are more effective in enhancing colloid transport in quartz beds than in enhancing colloid stability. Other effects are discussed.

Deriving meaningful climate-effects data from social media  

NASA Astrophysics Data System (ADS)

This paper presents our research on extracting meaningful climate indicator data from unsolicited observations ("tweets") made by Twitter users regarding their physical surroundings and events occurring around them. Our goal is to establish whether the existing understanding of climate indicator data collected by more traditional means could be usefully supplemented by information derived from the potentially rich but also statistically diffuse data resource represented by social media. To this end, we've initiated an ongoing effort to collect and analyze Twitter observations made on a wide variety of climate-related phenological, biological, epidemiological and meteorological phenomena. We report on our acquisition methodology and discuss in particular our rationale for selecting keywords, phrases and filters for our searches. The iterative process of assembling an inventory of hundreds of climate-related search terms has in and of itself yielded interesting and sometimes surprising insights on what is and isn't noticed and commented on via social media with respect to climate indicator phenomenology. We report some of the highlights of those analyses along with significant findings from the data acquisition to date. In conclusion, we discuss our preliminary assessment of the approach, how it can be generalized and extended for social media other than Twitter, and how the resulting data could be used to serve climate science objectives.

Data communications  

SciTech Connect

The purpose of this paper is to recommend regulatory guidance for reviewers examining computer communication systems used in nuclear power plants. The recommendations cover three areas important to these communications systems: system design, communication protocols, and communication media. The first area, system design, considers three aspects of system design--questions about architecture, specific risky design elements or omissions to look for in designs being reviewed, and recommendations for multiplexed data communication systems used in safety systems. The second area reviews pertinent aspects of communication protocol design and makes recommendations for newly designed protocols or the selection of existing protocols for safety system, information display, and non-safety control system use. The third area covers communication media selection, which differs significantly from traditional wire and cable. The recommendations for communication media extend or enhance the concerns of published IEEE standards about three subjects: data rate, imported hazards and maintainability.

Effective Communication with Cultural Heritage Using Virtual Technologies  

NASA Astrophysics Data System (ADS)

Cultural heritage is neither static nor stable. There is a need to explore ways for effectively communicating with cultural heritage to tourists and society at large, in an age of immediacy, a time of multiple realities and to multi-cultural tourists. It is vital to consider cultural heritage as a creative and relational process where places and communities are constantly remade through creative performance. The paper introduces virtual technologies as an approach to attain effective communication with cultural heritage. This approach emphasizes the importance of "user, content and context" in guiding the production of virtual heritage, as opposed to technology being the sole motivator. It addresses how these three issues in virtual heritage need to be transformed from merely representing quantitative data towards cultural information using the proposed effective communication triangle through representing meaningful relationships between cultural heritage elements, users and context. The paper offers a focused articulation of a proposed computational platform of "interactive, personalized and contextual-based navigation" with Egyptian heritage monuments as a one step forward towards achieving effective communication with Egyptian cultural heritage.

Effects of Various Suspending Media on Plaque Formation by Rickettsiae in Tissue Culture  

PubMed Central

Effects of some media used for suspending rickettsiae during purification, for metabolic studies, and in titrations of infectious rickettsiae were examined with respect to the plaque-forming ability of Rickettsia rickettsi and R. typhi in primary chicken embryo tissue cultures and the infectivity of R. typhi in mice. Brain heart infusion broth (BHI) was found superior to all other media tested in preventing both a significant decrease in plaque-forming units (PFU) and a delay in plaque formation. Skim milk, egg yolk, and some metabolic media were effective in maintaining PFU at 0 C, but did not prevent a significant delay in plaque formation. However, infectivity of R. typhi for tissue culture and mice was markedly decreased when suspended in metabolic media at 26 C. Addition of BHI to the routine tissue culture overlay reversed the deleterious effects of sucrose-phosphate solutions. The effects of Mg2+, Mn2+, K+, Na+, sucrose, and glutamate were also examined. No significant differences were observed between R. rickettsi and R. typhi in their responses to different media. The results of this study suggest the necessity for a reappraisal of previous studies of metabolism and infectivity of rickettsiae in these media. Images PMID:4673757

Gun violence and media effects: challenges for science and public policy.  

PubMed

In response to the Sandy Hook shooting in December 2012, the White House published an action plan to reduce gun violence that, among other things, calls for research into the relationship with violence in digital games or other media images. We acknowledge the administration's efforts to reduce violent crime in society and their obligation to dedicate resources to matters of public interest, such as media effects. However, research projects launched in the midst of a moral panic bear the risk of introducing bias and distracting from more important issues. Ideological rigidity has repeatedly shaped past research on media violence. Current initiatives could be an opportunity to restore credibility to the field and to engage in a responsible dialogue on media effects. In order to inform public policy, we need to close gaps, both in empirical research and the academic debate, while being alert for potential political and social influences. PMID:24187065

Two experiments were conducted to assess the degree to which violent media stimulate violent fantasy as depicted on inkblot responses. In Experiment I, 41 gifted high school students were exposed to a bucolic or violent film clip and then were asked to produce inkblot responses. In Experiment II, a second sample of 43 additional students were exposed to a verbal description of the bucolic or violent scene to assess whether the "hot" or "cooler" media (McLuhan, 1964) had different effects on the inkblot responses. In both experiments, the media exposure led to increased levels of violent responses, and in both cases males produced more violent responses. There was no sex by media interaction effect. Implications for clinical and forensic assessments are presented. PMID:10348406

Cross-Cultural Barriers to Effective Communication in Aviation  

NASA Technical Reports Server (NTRS)

Recent research on communication and performance in airline flight crews has led to a concept of shared mental models that is associated with effective, efficient team coordination in problem solving and decision making situations. Elements that characterize efficient communication have been identified. This research, however, was based strictly on US crews. More recent studies supported by NASA have identified cultural factors that influence communication among team members who vary in their status and roles. Research is just beginning to identify commonalities and culturally distinct strategies for accomplishing joint tasks. ASRS incident reports have been analyzed to identify language barriers in flight that have safety consequences. Implications of these concepts and findings for multi-cultural command and control will be explored.

Relativistic Doppler effect in quantum communication  

E-print Network

When an electromagnetic signal propagates in vacuo, a polarization detector cannot be rigorously perpendicular to the wave vector because of diffraction effects. The vacuum behaves as a noisy channel, even if the detectors are perfect. The ``noise'' can however be reduced and nearly cancelled by a relative motion of the observer toward the source. The standard definition of a reduced density matrix fails for photon polarization, because the transversality condition behaves like a superselection rule. We can however define an effective reduced density matrix which corresponds to a restricted class of positive operator-valued measures. There are no pure photon qubits, and no exactly orthogonal qubit states.

Cross-Cultural Barriers to Effective Communication in Aviation  

NASA Technical Reports Server (NTRS)

Communication is essential to safe flight, as evidenced by several accidents in which crew communicates was found to have contributed to the accidents. This chapter documents the essential role of explicit efficient communication to flight safety with a global context. It addresses communication between flight crews and air traffic controllers in regions a the world where pilots and controllers speak different native languages, as well as cases in which crew members within the flight deck represent different native languages and cultures. It also addresses problems associated with "exporting" crew resource management training programs to parts of the world which values and norms differ from those of the United States, where these programs were initially developed. This chapter is organized around several central questions: (1) What are various kinds of communication failures and what are their consequences; (2) What are the causes of communication failure; (3) What are features of effective crew communication; (4) What can be done to enhance communication success? To explore a wider range of communication failures than available from accident reports, we examined a set of incident reports from the Aviation Safety Reporting System. These could be classified into three major categories: those in which language actually interfered with transmission of a message; those in which transmission was adequate but the context was not expressed unambiguously and thus the message received was not the same as the message intended; and those in which the message was received as intended, but was not adequately understood or acted upon, mainly because of cultural factors. The consequences of failed communication can be flight errors (such as when a clearance is not received correctly), loss of situation awareness, or failure of crew members (or ATC and pilots) to build a shared understanding of a situation. Causes of misunderstanding can be traced to a number of sources, often grounded in faulty assumptions held by one or both parties to a conversation. Speakers and listeners often experience "illusionary understanding" in which they think they understand each other, but in fact do not. While this problem can exist within a single culture, it is much more serious across cultures. Training in effective explicit communication is a component of Crew Resource Management training programs developed in the U.S. These programs are being adopted by airlines around the world, with varying degrees of success. The level of success in part depends on how similar the conversational and social styles of those cultures are to those of the U.S. A factor that influences conversational style is a culture's relative positioned on two major dimensions that distinguish national cultural groups: individualism vs. collectivism and degree of power distance. The chapter concludes with a discussion of techniques for overcoming the various classes of communication failures and for effectively adapting training programs to fit the values and norms of cultures around the globe.

The effects of media on pharmaceutically relevant transporters in the human HT-29 adenocarcinoma cell line: does culture media need to be controlled?  

PubMed

The HT-29 cell line forms a confluent monolayer with tight junctions, but displays different phenotypes when cultured for 21 days in galactose-supplemented media (differentiated) versus glucose-supplemented media (dedifferentiated). This study is aimed at elucidating how media differences might affect selected drug transporter expression and peptide-based substrate transport toward reducing this variability. A vial of HT-29 cells was amplified and cultured over several passages in four different mediums (American Type Culture Collection recommended McCoy's 5A versus Dulbecco's modified Eagle's media containing glucose, galactose, or neither carbohydrate) with normal supplementation. Transporter mRNA expression was characterized at days 5 and 21 postseeding utilizing SABiosciences quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR) drug transporter arrays. Transport studies using [H]histidine, [(3) H]glycylsarcosine, [(3) H]valacyclovir, and [(3) H]carnosine were performed to assess the functional effects of oligopeptide transporter expression changes in HT-29 cells grown in each media. qRT-PCR arrays illustrated variable, media-dependent transporter expression between both the initial and differentiated time points. Permeability studies illustrated considerable media-dependent differences in both paracellular and transcellular substrate fluxes. The results demonstrate that these cells exhibit differing monolayer characteristics and genotypic/phenotypic profile properties when cultured under different media. The results suggest a need for standardization of culture methodologies for reducing inter- and intralaboratory variability. PMID:22213613

Effects of magnetic states in recording media on moisture adsorption and surface hydrophobicity  

NASA Astrophysics Data System (ADS)

In magnetic data recording, humidity is the most dangerous environmental factor that affects the stability of storage media carriers. It will lead to the magnetic media deterioration and also adversely affect the tribological performance at the head-disk interface. At every data bit of recording, the transition area in a longitudinal recording media has a near-perpendicular magnetic direction, either at north or south magnetic polarity. This investigation showed that a perpendicularly magnetized floppy disk at the south polarity was able to retain and adsorb water molecules into its coating media. The north polarity was found to have shown the exact opposite effect. As a result of this phenomenon, the physical surface condition and the surface hydrophobicity of a magnetized floppy disk has been affected. The interaction with moisture from the south-polarized disk could become ideal sites for fungus growth, which eventually affects the carrier's stability and its tribological performance.

Effect of pore structure on gas trapping in porous media  

NASA Astrophysics Data System (ADS)

Capillary trapping of nonwetting phase in porous media plays an important role in many geological processes. For example, large portions of hydrocarbons cannot be extracted from reservoirs due to capillary forces, while in carbon sequestration processes; capillary trapping might improve the storage efficiency. An important case is when the wetting phase (mostly water) displaces a low-viscosity low-density fluid. In such cases, like water encroachment into gas reservoirs or rising of water table in soils, competition of gravity, viscous, and capillary forces determines the final configuration of the fluids in invaded zone. The trapped nonwetting phase and its distribution within the porous media will affect many other processes such as flow of the other fluids and mass transfer phenomena. Thus, investigating the parameters affecting phase trapping and distribution, especially their relation to pore structure, which controls the capillary action, is required. The aim is to predict gas trapping from structural properties of the material. We conducted a series of column experiments, in which water displaces air at a range of flow rates in different glass-bead packs. The final 3D configuration and morphology of fluids was observed using X-Ray Computed Tomography (CT). We extracted 3D structure of porous media as well as of the trapped gas phase, and quantified them in terms of volume ratios, interfacial area, and morphology. Then we investigated the relations of the trapped phase to capillary forces (pore structure) and viscous forces (front velocity). The results give us new insights to explore the flow and dissolution processes: We found no systematic dependency of the front velocity of the invading water phase in the velocity range from 0.1 to 0.6 cm/min what corresponds to capillary numbers from 2 to 12 ×10^-6. Our experimental results indicate that the capillary trapping mechanism is controlled by the local pore structure and local connectivity and not by thermodynamics, i.e. large pores are occupied first by the gas phase.

The effect of a health communication campaign on compliance with mass drug administration for schistosomiasis control in western Kenya--the SCORE project.  

PubMed

Compliance with mass drug administration (MDA) can be affected by rumors and mistrust about the drug. Communication campaigns are an effective way to influence attitudes and health behaviors in diverse public health contexts, but there is very little documentation about experiences using health communications in schistosomiasis control programs. A qualitative study was conducted with community health workers (CHWs) as informants to explore the effect of a health communication campaign on their experiences during subsequent praziquantel MDA for schistosomiasis. Discussions were audio-recorded, transcribed verbatim, translated into English where applicable, and analyzed thematically using ATLAS.ti software. According to the CHWs, exposure to mass media messages improved awareness of the MDA, which in turn, led to better treatment compliance. Our findings suggest that communication campaigns influence health behaviors and create awareness of schistosomiasis control interventions, which may ultimately improve praziquantel MDA.

Assessment of earthquake effects - contribution from online communication  

NASA Astrophysics Data System (ADS)

The rapid increase of social media and online newspapers in the last years have given the opportunity to make a national investigation on macroseismic effects on the Maltese Islands based on felt earthquake reports. A magnitude 4.1 earthquake struck close to Malta on Sunday 24th April 2011 at 13:02 GMT. The earthquake was preceded and followed by a series of smaller magnitude quakes throughout the day, most of which were felt by the locals on the island. The continuous news media coverage during the day and the extensive sharing of the news item on social media resulted in a strong public response to fill in the 'Did you feel it?' online form on the website of the Seismic Monitoring and Research Unit (SMRU) at the University of Malta (http://seismic.research.um.edu.mt/). The results yield interesting information about the demographics of the island, and the different felt experiences possibly relating to geological settings and diverse structural and age-classified buildings. Based on this case study, the SMRU is in the process of developing a mobile phone application dedicated to share earthquake information to the local community. The application will automatically prompt users to fill in a simplified 'Did you feel it?' report to potentially felt earthquakes. Automatic location using Global Positioning Systems can be incorporated to provide a 'real time' intensity map that can be used by the Civil Protection Department.

Absorption of Microdrops: Effect of Multi-Layer Porous Media Structure Parameters  

NASA Astrophysics Data System (ADS)

This paper presents the numerical investigation of the absorption of two microdrops deposited sequentially on the surface of single- and double-layer porous media at a different location of the centers of droplets deposition. A numerical solution of the Euler equations taking into account surface tension forces and the unsteady filtration equation was used to model the fluid flow from a droplet into a porous media. The layers of porous media were characterized by effective permeability coefficients dependent on porosity and pore size. The change of the droplet shape during absorption, the coordinates of absorption front propagation in a porous media and the field of velocities and pressure are the output data of a problem. The effect of the structural parameters of the multilayer porous media and the relative location of deposited droplets on the rate of absorption and distribution of absorbed fluid is analyzed using the numerical experiment. It is shown that the presence of the second layer can have a significant effect on the duration and result of droplet absorption. The relative size of pore in layers is found to be the main parameter that governs the effect of the second layer.

Self-transparency effects in heterogeneous nonlinear scattering media and their possible use in lasers  

NASA Astrophysics Data System (ADS)

Transmission of intense laser beams through heterogeneous scattering media is considered. Effects of intensity limitation, self-recovery of the wave front of a transmitted beam, and bistable reflection associated with the laser-induced self-transparency (suppression of scattering) of such media are predicted because of the compensation of the linear refractive-index difference of the heterocomponents of a medium by nonlinear change for different mechanisms of nonlinearity. Applications of these effects in lasers for Q switching and mode locking are discussed. The observation of self-transparency effects in several heterogeneous media (glass particles in toluene and nitrobenzene, and lead molybdenite powder) for CW Ar- and pulsed Nd- and CO2-laser radiation is reported. Q switching and mode locking have also been demonstrated with a YAG:Nd laser using nonlinear scattering in a heterogeneous cell as a control element in a laser resonator.

On effectiveness of routing algorithms for satellite communication networks  

NASA Astrophysics Data System (ADS)

For worldwide, a satellite communication network is an integral component of the global networking infrastructure. In this paper, we focus on developing effective routing techniques that consider both user preferences and network dynamic conditions. In particular, we develop a weighted-based route selection scheme for the core satellite communication network. Unlike the shortest path routing scheme, our scheme chooses the route from multiple matched entries based on the assigned weights that reflect the dynamic condition of networks. We also discuss how to derive the optimal weights for route assignment. To further meet user's preference, we implement the multiple path routing scheme to achieve the high rate of data transmission and the preemption based routing scheme to guarantee the data transmission for high priority users. Through extensive simulation studies, our data validates the effectiveness of our proposed routing schemes.

Effective Communication and File-I/O Bandwidth Benchmarks  

SciTech Connect

We describe the design and MPI implementation of two benchmarks created to characterize the balanced system performance of high-performance clusters and supercomputers: b{_}eff, the communication-specific benchmark examines the parallel message passing performance of a system, and b{_}eff{_}io, which characterizes the effective 1/0 bandwidth. Both benchmarks have two goals: (a) to get a detailed insight into the Performance strengths and weaknesses of different parallel communication and I/O patterns, and based on this, (b) to obtain a single bandwidth number that characterizes the average performance of the system namely communication and 1/0 bandwidth. Both benchmarks use a time driven approach and loop over a variety of communication and access patterns to characterize a system in an automated fashion. Results of the two benchmarks are given for several systems including IBM SPs, Cray T3E, NEC SX-5, and Hitachi SR 8000. After a redesign of b{_}eff{_}io, I/O bandwidth results for several compute partition sizes are achieved in an appropriate time for rapid benchmarking.

The challenge of effectively communicating patient safety information.  

PubMed

Rational use of drugs and patient safety are seriously compromised by a lack of good information, education and effective communication at all stages of drug development and use. From animal trials through to dispensing, there are misconceptions and opportunities for error which current methods of drug information communication do not adequately address: they do not provide those responsible for prescribing and dispensing drugs with the data and information they need to pass on complex and often changing messages to patients and the public. The incidence of adverse reactions due to the way drugs are used; the variable impact of regulatory guidelines and warnings on prescribing behaviour; drug scares and crises suggest a great gap between the ideals of the safe use of medicines and the reality in homes, clinics and hospitals around the world. To address these challenges, the authors review the several levels at which safety information is generated and communicated, and examine how, at each stage, the content and its significance, and the method of communication can be improved.

We investigate the consequences of space-time being curved on space-based quantum communication protocols. We analyze tasks that require either the exchange of single photons in a certain entanglement distribution protocol or beams of light in a continuous-variable quantum key distribution scheme. We find that gravity affects the propagation of photons, therefore adding additional noise to the channel for the transmission of information. The effects could be measured with current technology.

Quantifying the Persistence of Pro-Smoking Media Effects on College Students’ Smoking Risk  

PubMed Central

Purpose To quantify the persistence of pro-smoking media exposure effects on college students’ intentions to smoke and smoking refusal self-efficacy. Method A total of 134 college students (ages 18–24) were enrolled in an ecological momentary assessment study in which they carried handheld data collection devices for three weeks and reported their exposures to pro-smoking media as they occurred in the real world. Smoking intentions and smoking refusal self-efficacy were assessed after each exposure to pro-smoking media and at random prompts during each day of the three-week assessment period. A generalized additive model was used to determine how long the effect of an exposure to pro-smoking media persisted. Results The effect of pro-smoking media exposures persisted for 7 days. After exposure, smoking intentions immediately increased (0.56; 95% confidence interval [CI]: [0.26, 0.87]) and then steadily decreased (?0.12; 95% CI: [?0.19, ?0.05]) each day for 7 days, while smoking refusal self-efficacy immediately decreased (?0.42; 95% CI: [?0.75, ?0.10]) and then steadily increased (0.09; 95% CI: [0.02, 0.16]) each day for 7 days. Daily changes occurring after 7 days were not statistically significant, suggesting that smoking intentions and refusal self-efficacy had stabilized and were no longer affected by pro-smoking media exposure. Conclusions Exposures to pro-smoking media may have strong implications for emerging young adults smoking risk as the impact of an individual exposure appears to persist for at least a week.

Effect of different temperature and culture media on the growth of Macrophomina phaseolina.  

PubMed

The charcoal root disease caused by Macrophomina phaseolina (Tassi) Goidanich may cause considerable damages in hot as well as in dry seasons. The effect of temperature and culture media were studied on the growing patterns of 35 M. phaseolina isolates, collected from different districts of Hungary. The isolates were grown at 10, 15, 20, 25, 30, 35 and 40 degrees C temperatures respectively, and additionally at 25 degrees C on potato-dextrose-, malt-extract-, Czapek-Dox-, Sabouraud-glucose-, maize-flour- and watery agar media, using 90 mm Petri-dishes, 4 repetitions in each case. For all the isolates the most favourable temperature regime was 25 to 35 degrees C and the most advantageous media was the malt-extract-, Sabouraud-glucose- and potato-dextrose-agar media. At these conditions (temperatures and culture media) mycelia growth and the diameter of microsclerotial colonies reached the 90 mm at the 5th day. Mycelia growth of the pathogen was very low at 10, 15 and 40 degrees C, and did not form microsclerotia. On watery agar microsclerotial colony seldom developed, it needed 14 days, and no continuous mycelia developed even in a 8th months culture. Diameter of microsclerotia measured on different culture media varied between 39-308 microm. PMID:18396819

Simulation on effects of porosity pattern arrangement of porous media during drying  

NASA Astrophysics Data System (ADS)

The computational simulation results on the moisture transport within a porous media are presented in this paper. The porous media is simulated using models arranged in two patterns. The models consist of spheres representing the porosity of the media. The remaining void volume within the models is set as water. The spheres are arranged in two patterns, which are in-line cascaded and diagonally-cascaded. These pattern arrangements can aid the observation on the possible different transport paths of the moisture content within the porous media during drying operation. The models are simulated using boundary conditions such as outlet being set as atmospheric condition, materials of the spheres and water temperature. Simulation results are shown in contour plots around the spheres and void volume to illustrate the fluid velocity magnitude during the transport of the moisture content. Comparisons are also presented for the two models with different cascading patterns. Results show differences in magnitudes of velocity which indicates different moisture transport. These simulation results can also help distinguish the effects of different porosity arrangement on the moisture transport within the porous media especially during drying of the porous media. These models can also be used as initial simulation models for materials such as ceramic tiles.

Ameliorative effect of melatonin against contrast media induced renal tubular cell injury  

PubMed Central

Background and Objective: Reactive oxygen species (ROS) is a mediator of renal damage. Melatonin is a potent-free radical scavenger. Our objective was to test whether melatonin would protect against the nephrotoxicity of contrast media. Methods: In an experimental study 40 adult male Wistar rats were randomly divided into four equal groups including: 1) Control group (No drug), 2) Contrast media group (10 ml/kg iodixanol i.v. single dose), 3) Contrast media and melatonin (first 10 ml/kg iodixanol then 10 ml/kg/day melatonin by i.p. injection on days 3, 4 and 5) and 4) Contrast media and melatonin pretreatment group (melatonin 10 ml/ kg/day by i.p. injection on 1, 2 and 3 days, then 10 ml/kg iodixanol by i.v. injection on third day. The blood creatinine and BUN as well as the histological changes were evaluated for severity of renal injury (degeneration, vacuolization of tubular renal cells, dilatation of tubular lumen and presence of debris in the lumens), by scoring from one to four. Results: Contrast media significantly increased the creatinine and BUN and renal injury (p<0.05). Melatonin prevented and reversed the injury induced by contrast media (P<0.05). Pretreatment with melatonin reduced the renal injury induced by contrast media (P<0.05). Conclusion: Melatonin is an effective drug to prevent contrast–induced renal injury. Therefore its usage (especially pretreatment) might be beneficial in patients who are planning to use contrast media agents. PMID:24772123

Quantitative dosimetric assessment for effect of gold nanoparticles as contrast media on radiotherapy planning  

NASA Astrophysics Data System (ADS)

In CT planning for radiation therapy, patients may be asked to have a medical procedure of contrast agent (CA) administration as required by their physicians. CA media improve quality of CT images and assist radiation oncologists in delineation of the target or organs with accuracy. However, dosimetric discrepancy may occur between scenarios in which CA media are present in CT planning and absent in treatment delivery. In recent preclinical experiments of small animals, gold nanoparticles (AuNPs) have been identified as an excellent contrast material of x-ray imaging. In this work, we quantitatively evaluate the effect of AuNPs to be used as a potential material of contrast enhancement in radiotherapy planning with an analytical phantom and clinical case. Conray 60, an iodine-based product for contrast enhancement in clinical uses, is included as a comparison. Other additional variables such as different concentrations of CA media, radiation delivery techniques and dose calculation algorithms are included. We consider 1-field AP, 4-field box, 7-field intensity modulated radiation therapy (IMRT) and a recent technique of volumetric modulated arc therapy (VMAT). CA media of AuNPs (Conray 60) with concentrations of 10%, 20%, 30%, 40% and 50% containing 28.2, 56.4, 84.6, 112.8 and 141.0 mg of gold (iodine) per mL were prepared prior to CT scanning. A virtual phantom with a target where nanoparticle media are loaded and clinical case of gastric lymphoma in which the Conray 60 media were given to the patient prior to the CT planning are included for the study. Compared to Conray 60 media with concentration of 10%/50%, Hounsfield units for AuNP media of 10%/50% are 322/1608 higher due to the fact that atomic number of Au (Z=79) is larger than I (Z=53). In consequence, dosimetric discrepancy of AuNPs is magnified between presence and absence of contrast media. It was found in the phantom study that percent dose differences between presence and absence of CA media may be reduced by delivery techniques of 7-field IMRT or VMAT. To manage less than 3% of percent dose difference, it was suggested an upper limit of 15% (or 42.3 mg Au/mL) of AuNP media in the phantom study; 8% (or 22.5 mg Au/mL) in the specific clinical case.

New media, old media: The technologies of international development  

NASA Astrophysics Data System (ADS)

The research, theory and practice of educational technology over the past 75 years provide convincing evidence that this process offers a comprehensive and integrated approach to solving educational and social problems. The use of media and technology in development has shifted from an emphasis on mass media to personal media. A variety of electronic delivery systems are being used and are usually coordinated by centralized governmental agencies. There are no patterns of use since the problems vary and the medium used is responsive to the problem. Computers are used most frequently and satellite telecommunication networks follow. The effective use of these and other technologies requires a long-term commitment to financial support and training of personnel. The extension model of face-to-face contact still prevails in developing nations whether in agriculture, education or rural development. Low-cost technologies are being used in local projects while major regional and national companies use radio, film and related video technologies. The use of all available and cost-effective media and technologies make possible appropriate communications for specific goals with specific audiences. There appears to be no conflict among proponents of various media formats. Development in education and other sectors has much to gain from old and new communication technologies and has hardly been tapped. Several new educational technology developments are discussed as potential contributors to formal and nonformal education.

The Constitutive Relations and the Magnetoelectric Effect for Moving Media  

E-print Network

In this paper the constitutive relations for moving media with homogeneous and isotropic electric and magnetic properties are presented as the connections between the generalized magnetization-polarization bivector $%\\mathcal{M}$ and the electromagnetic field F. Using the decompositions of F and $\\mathcal{M}$, it is shown how the polarization vector P(x) and the magnetization vector M(x) depend on E, B and two different velocity vectors, u - the bulk velocity vector of the medium, and v - the velocity vector of the observers who measure E and B fields. These constitutive relations with four-dimensional geometric quantities, which correctly transform under the Lorentz transformations (LT), are compared with Minkowski's constitutive relations with the 3-vectors and several essential differences are pointed out. They are caused by the fact that, contrary to the general opinion, the usual transformations of the 3-vectors $% \\mathbf{E}$, $\\mathbf{B}$, $\\mathbf{P}$, $\\mathbf{M}$, etc. are not the LT.

Effects of starvation on bacterial transport through porous media  

NASA Astrophysics Data System (ADS)

A major problem preventing widespread implementation of microbial injection strategies for bioremediation and/or microbially enhanced oil recovery is the tendency of bacteria to strongly adhere to surfaces in the immediate vicinity of the injection point. Long term (weeks to months) nutrient starvation of bacteria prior to injection can decrease attachment and enhance transport through porous media. This paper summarizes results of starvation-enhanced transport experiments in sand columns of 30 cm, 3 m, and 16 m in length. The 16 m column experiments compared transport, breakthrough and distribution of adhered cells for starved and vegetative cultures of Klebsiella oxytoca, a copious biofilm producer. Results from these experiments were subsequently used to design and construct a field-scale biofilm barrier using starved Pseudomonas fluorescens. The 30 cm and 3 m sand columns experiments investigated starvation-enhanced transport of Shewanella algae BrY, a dissimilatory metal-reducing bacterium. In both cases the vegetative cells adsorbed onto the sand in higher numbers than the starved cells, especially near the entrance of the column. These results, taken together with studies cited in the literature, indicate that starved cells penetrate farther (i.e. higher breakthrough concentration) and adsorb more uniformly along the flow path than vegetative cells.

The bioavailability and toxicity of trace metals to aquatic microbiota are influenced by the chemical form (aqueous species) of the metal. However, the interpretation of bioassay results, and the extrapolation of these results to in situ conditions, is often complicated by the inclusion of complex soluable organics in the bioassay media. This investigation (1) evaluates the effects of complex soluable organics on the acute toxicity of mercury (II) to a Pseudomonas fluorescens isolate in a chemically well-defined synthetic growth media, (2) computes the effects of these organics on the aqueous speciation of mercury (II) in the media, and (3) ascertains the dependence of toxicity on the chemical speciation of mercury (II). 25 refs., 3 figs., 6 tabs.

Effects of Mass Media Coverage on Timing and Annual Receipt of Influenza Vaccination among Medicare Elderly  

PubMed Central

Objective To measure the association between mass media coverage on flu-related topics and influenza vaccination, regarding timing and annual vaccination rates, among the nationally representative community-dwelling elderly. Data Source Years 1999, 2000, and 2001 Medicare Current Beneficiary Survey. Study Design Cross-sectional survival analyses during each of three influenza vaccination seasons between September 1999 and December 2001. The outcome variable was daily vaccine receipt. We measured daily media coverage by counting the number of television program transcripts and newspaper/wire service articles, including keywords of influenza/flu and vaccine/shot shortage/delay. All models' covariates included three types of media, vaccine supply, and regional/individual factors. Principal Findings Influenza-related reports in all three media sources had a positive association with earlier vaccination timing and annual vaccination rate. Four television networks' reports had most consistent positive effects in all models, for example, shifting the mean vaccination timing earlier by 1.8–4.1 days (p<.001) or increasing the annual vaccination rate by 2.3–7.9 percentage points (p<.001). These effects tended to be greater when reported in a headline rather than in text only and if including additional keywords, for example, vaccine shortage/delay. Conclusions Timing and annual receipt of influenza vaccination appear to be influenced by media coverage, particularly by headlines and specific reports on shortage/delay. PMID:20579128

The effect of priming materialism on women's responses to thin-ideal media.  

PubMed

Consumer culture is characterized by two prominent ideals: the 'body perfect' and the material 'good life'. Although the impact of these ideals has been investigated in separate research literatures, no previous research has examined whether materialism is linked to women's responses to thin-ideal media. Data from several studies confirm that the internalization of materialistic and body-ideal values is positively linked in women. After developing a prime for materialism (N = 50), we present an experimental examination (N = 155) of the effects of priming materialism on women's responses to thin-ideal media, using multiple outcome measures of state body dissatisfaction. Priming materialism affects women's body dissatisfaction after exposure to thin media models, but differently depending on the dimension of body image measured. The two main novel findings are that (1) priming materialism heightens the centrality of appearance to women's self-concept and (2) priming materialism influences the activation of body-related self-discrepancies (BRSDs), particularly for highly materialistic women. Exposure to materialistic media has a clear influence on women's body image, with trait materialism a further vulnerability factor for negative exposure effects in response to idealized, thin media models.

Investigating effects of communications modulation technique on targeting performance  

NASA Astrophysics Data System (ADS)

One of the key challenges facing the global war on terrorism (GWOT) and urban operations is the increased need for rapid and diverse information from distributed sources. For users to get adequate information on target types and movements, they would need reliable data. In order to facilitate reliable computational intelligence, we seek to explore the communication modulation tradeoffs affecting information distribution and accumulation. In this analysis, we explore the modulation techniques of Orthogonal Frequency Division Multiplexing (OFDM), Direct Sequence Spread Spectrum (DSSS), and statistical time-division multiple access (TDMA) as a function of the bit error rate and jitter that affect targeting performance. In the analysis, we simulate a Link 16 with a simple bandpass frequency shift keying (PSK) technique using different Signal-to-Noise ratios. The communications transfer delay and accuracy tradeoffs are assessed as to the effects incurred in targeting performance.

In the past, a mainstay of scientific communication in popular media was through science “translators”; science journalists and presenters. These have now nearly disappeared and are being replaced by widespread dissemination through, e.g., the internet, blogs, YouTube and journalists who often have little scientific background and sharp deadlines. Thus, scientists are required to assume increasing responsibility for translating their scientific findings and calibrating their communications to non-technical audiences, a task for which they are often ill prepared, especially when it comes to controversial societal issues such as tobacco, evolution, and most recently climate change (Oreskes and Conway 2010). Such issues have been politicized and hi-jacked by ideological belief systems to such an extent that constructive dialogue is often impossible. Many scientists are excellent communicators, to their peers. But this requires careful attention to detail and logical explanation, open acknowledgement of uncertainties, and dispassionate delivery. These qualities become liabilities when communicating to a non-scientific audience where entertainment, attention grabbing, 15 second sound bites, and self assuredness reign (e.g. Olson 2009). Here we report on a program initiated by NCAR and UCAR to develop new approaches to science communication and to equip present and future scientists with the requisite skills. If we start from a sound scientific finding with general scientific consensus, such as the warming of the planet by greenhouse gases, then the primary emphasis moves from the “science” to the “art” of communication. The art cannot have free reign, however, as there remains a strong requirement for objectivity, honesty, consistency, and above all a resistance to advocating particular policy positions. Targeting audience attitudes and beliefs, which studies such as the Six Americas research help identify, is key to effective science communications (e.g. Leiserowitz, Maibach, et al, 2009). We argue that the impact of the scientific message can be substantially improved by targeting it to these additional factors. This does require an understanding of the audience and a repackaging of the message to different societal groups. Logical and dispassionate presentation of evidence works for a target scientific audience, but major decisions from the policy to the personal level are influenced by many factors including immediacy, economics, culture, community leaders, emotional framing, and ideological filters.

Multi-level functionality of social media in the aftermath of the Great East Japan Earthquake.  

PubMed

This study examines the multi-level functionalities of social media in the aftermath of the Great East Japan Earthquake of 11 March 2011. Based on a conceptual model of multi-level story flows of social media (Jung and Moro, 2012), the study analyses the multiple functionalities that were ascribed to social media by individuals, organisations, and macro-level social systems (government and the mass media) after the earthquake. Based on survey data, a review of Twitter timelines and secondary sources, the authors derive five functionalities of social media: interpersonal communications with others (micro level); channels for local governments; organisations and local media (meso level); channels for mass media (macro level); information sharing and gathering (cross level); and direct channels between micro-/meso- and macro-level agents. The study sheds light on the future potential of social media in disaster situations and suggests how to design an effective communication network to prepare for emergency situations. PMID:24905811

Effective physician-nurse communication: a patient safety essential for labor and delivery.  

PubMed

Effective communication is a hallmark of safe patient care. Challenges to effective interprofessional communication in maternity care include differing professional perspectives on clinical management, steep hierarchies, and lack of administrative support for change. We review principles of high reliability as they apply to communication in clinical care and discuss principles of effective communication and conflict management in maternity care. Effective clinical communication is respectful, clear, direct, and explicit. We use a clinical scenario to illustrate an historic style of nurse-physician communication and demonstrate how communication can be improved to promote trust and patient safety. Consistent execution of successful communication requires excellent listening skills, superb administrative support, and collective commitment to move past traditional hierarchy and professional stereotyping.

Wireless communication with chaos.  

PubMed

The modern world fully relies on wireless communication. Because of intrinsic physical constraints of the wireless physical media (multipath, damping, and filtering), signals carrying information are strongly modified, preventing information from being transmitted with a high bit rate. We show that, though a chaotic signal is strongly modified by the wireless physical media, its Lyapunov exponents remain unaltered, suggesting that the information transmitted is not modified by the channel. For some particular chaotic signals, we have indeed proved that the dynamic description of both the transmitted and the received signals is identical and shown that the capacity of the chaos-based wireless channel is unaffected by the multipath propagation of the physical media. These physical properties of chaotic signals warrant an effective chaos-based wireless communication system. PMID:23683198

The foxconn suicides and their media prominence: is the werther effect applicable in china?  

PubMed Central

Background Media reporting of suicide and its relationship with actual suicide has rarely been investigated in Mainland China. The "Foxconn suicides" is a description referring to a string of suicides/attempts during 2010, all of which were related to a giant electrical manufacturing company, Foxconn. This study aimed to examine the clustering and copycat effects of the Foxconn suicides, and to investigate temporal patterns in how they were reported by the media in Mainland China, Hong Kong (HK), and Taiwan (TW). Methods Relevant articles were collected from representative newspapers published in three big cities in Mainland China (Beijing (BJ), Shenzhen (SZ), and Guangzhou (GZ)), HK, and TW, together with searching intensity data on the topic conducted using the Baidu search engine in Mainland China. The temporal clustering effects of the Foxconn suicides and their media prominence were assessed using the Kolmogorov-Smirnov test. The media reports of the Foxconn suicides' temporal patterns were explored using a nonparametric curve estimation method (that is, the local linear method). The potential mutual interactions between the Foxconn suicides and their media prominence were also examined, using logistic and Poisson regression methods. Results The results support a temporal clustering effect for the Foxconn suicides. The BJ-based newspapers' reporting and the occurrence of a Foxconn suicide/attempt are each found to be associated with an elevated chance of a further Foxconn suicide 3 days later. The occurrence of a Foxconn suicide also immediately influenced the intensity of both Baidu searching and newspaper reporting. Regional diversity in suicide reporting tempo-patterns within Mainland China, and similarities between HK and TW, are also demonstrated. Conclusions The Foxconn suicides were temporally clustered. Their occurrences were influenced by the reporting of BJ-based newspapers, and contagion within the company itself. Further suicide research and prevention work in China should consider its special media environment. PMID:22044598

The Effects of a Mass Media HIV-Risk Reduction Strategy on HIV-Related Stigma and Knowledge Among African American Adolescents.  

PubMed

HIV-related stigma undermines HIV prevention, testing, and treatment. Multipronged risk-reduction strategies may reduce stigma among African American adolescents. To test the effectiveness of a risk-reduction strategy in addressing stigma, 1613 African American adolescents from four mid-sized cities participated in a randomized control trial. Participants received a sexual-risk reduction [Focus on Youth (FOY)] or general health curriculum [Promoting Health Among Teens (PHAT)]. Two cities received a culturally-tailored media intervention. Participants completed baseline, 3-, 6-, and 12-month surveys to measure HIV-related stigma and knowledge. Analysis of covariance tested for stigma and knowledge differences by media city status and curriculum/media city status (PHAT media vs. PHAT non-media, FOY media vs. FOY non-media; FOY media vs. PHAT media; FOY non-media vs. PHAT non-media) at each measurement. Hierarchical linear modeling (HLM) determined stigma and knowledge differences over time. Media participants demonstrated greater HIV-related knowledge (p<0.10) at 6 months and lower stigma at 3 months (p<0.10). FOY media participants had lower 3-month (p<0.05) and 12-month (p<0.10) stigma scores than non-media FOY participants. FOY media and non-media participants had greater knowledge than PHAT for all intervals after baseline. FOY media had lower stigma than PHAT media after baseline for all intervals after baseline. HLM indicated greater knowledge slopes for the media group (p<0.05). FOY media participants had greater knowledge slopes (p<0.05) relative to non-media FOY participants and media PHAT participants (p<0.01). A combination of a HIV risk-reduction curriculum and culturally-tailored media demonstrated some effectiveness in reducing stigma. Future use of media in HIV-prevention should include and evaluate effects on stigma. PMID:25738952
