Easy access to intervention and support for certain behaviors is important for obesity prevention and management. The available technology such as smartphone applications can be used for intervention regarding healthy food choices for obesity prevention and management in elementary-school students. The transtheoretical model (TTM) is comprised of stages and processes of change and can be adopted to tailored education for behavioral change. This study aims to develop TTM-based nutrition contents for mobile applications intended to change eating behaviors related to weight gain in young children. A synthesized algorithm for tailored nutrition messages was developed according to the intake status of six food groups (vegetables, fruits, sugar-sweetened beverages, fast food and instant food, snacks, and late-night snacks), decision to make dietary behavioral changes, and self-confidence in dietary behavioral changes. The messages in this study were developed from December 2014 to April 2015. After the validity evaluation of the contents through expert consultation, tailored nutrition information messages and educational contents were developed based on the TTM. Based on the TTM, stages of subjects are determined by their current intake status, decision to make dietary behavioral changes, and self-confidence in dietary behavioral changes. Three versions of tailored nutrition messages at each TTM stage were developed so as to not send the same messages for three weeks at most, and visual materials such as figures and tables were developed to provide additional nutritional information. Finally, 3,276 tailored nutrition messages and 60 nutrition contents for applications were developed. Smartphone applications may be an innovative medium to deliver interventions for eating behavior changes directly to individuals with favorable cost-effectiveness. In addition, using the TTM for tailored nutrition education for healthy eating is an effective approach.

The aim was to compare the effectiveness of untailored text messages for smoking cessation to tailored text messages delivered at a higher frequency. From February 2007 to August 2009, 2030 users of an internet-based smoking cessation program with optional text message support aged 15-25 years were...... consecutively randomized to versions of the program that offered either tailored or untailored text messages. Thirty-day point abstinence from smoking was measured self-reportedly at 12-months follow-up. Response rates were 36.3% and 38.1% in the tailored and untailored group, respectively. We analyzed...

The HIV TIPS project will pilot and evaluate the use of web-based information technology on prescription errors and quality of care by providing tailored practice guidelines and patient education in ambulatory practice settings of the National AIDS Education and Training Centers (NAETC) network. In the first phase of the project, we tailored messages to guide patient adherence and self-care, using DHHS guidelines. We developed a method based on communication theory to ensure complete and effective messages. PMID:14728437

Current HIV prevention options are unrealistic for most women; however, HIV prevention research has made important strides, including on-going development of antiretroviral-based vaginal microbicide gels. Nevertheless, social-behavioural research suggests that women's ability to access and use new HIV prevention technologies will be strongly influenced by a range of socio-cultural, gender and structural factors which should be addressed by communications and marketing strategies, so that these products can be positioned in ways that women can use them. Based on an extensive literature review and in-country policy consultation, consisting of approximately 43 stakeholders, we describe barriers and facilitators to HIV prevention, including potential microbicide use, for four priority audiences of Kenyan women (female sex workers [FSWs], women in stable and discordant relationships, and sexually active single young women). We then describe how messages that position microbicides might be tailored for each audience of women. We reviewed 103 peer-reviewed articles and reports. In Kenya, structural factors and gender inequality greatly influence HIV prevention for women. HIV risk perception and the ability to consistently use condoms and other prevention products often vary by partner type. Women in stable relationships find condom use challenging because they connote a lack of trust. However, women in other contexts are often able to negotiate condom use, though they may face challenges with consistent use. These women include FSWs who regularly use condoms with their casual clients, young women in the initial stages of a sexual relationship and discordant couples. Thus, we consider two approaches to framing messages aimed at increasing general awareness of microbicides - messages that focus strictly on HIV prevention and ones that focus on other benefits of microbicides such as increased pleasure, intimacy or sexual empowerment, in addition to HIV prevention.

Health messages can be tailored by applying different tailoring ingredients, among which personalisation, feedback and adaptation. This experiment investigated the separate effects of these tailoring ingredients on behaviour in auditory health persuasion. Furthermore, the moderating effect of self-efficacy was assessed. The between-participants design consisted of four conditions. A generic health message served as a control condition; personalisation was applied using the recipient's first name, feedback was given on the personal state, or the message was adapted to the recipient's value. The study consisted of a pre-test questionnaire (measuring fruit and vegetable intake and perceived difficulty of performing these behaviours, indicating self-efficacy), exposure to the auditory message and a follow-up questionnaire measuring fruit and vegetable intake two weeks after message exposure (n = 112). ANCOVAs showed no main effect of condition on either fruit or vegetable intake, but a moderation was found on vegetable intake: When self-efficacy was low, vegetable intake was higher after listening to the personalisation message. No significant differences between the conditions were found when self-efficacy was high. Individuals with low self-efficacy seemed to benefit from incorporating personalisation, but only regarding vegetable consumption. This finding warrants further investigation in tailoring research.

Although tailoring health education messages to individual characteristics of patients has shown promising results, most patient education materials still take a one-size-fits-all approach. The aim of this study was to develop a method for tailoring health education messages to patients' preferences for various message features, using the concept of personas. This is a preliminary study focused on education for coronary heart disease (CHD) patients. This study used a three-step approach. First, we created personas by (i) performing k-means cluster analysis on data from an online survey that assessed the preferences of 213 CHD patients for various message features and, (ii) creating a vivid description of the preferences per patient cluster in an iterative process with the research team. Second, we developed adaptation rules to tailor existing educational messages to the resulting personas. Third, we conducted a pilot validation by adapting nine existing educational messages to each of the personas. These messages and the resulting personas were then presented to a separate group of 38 CHD patients who visited the cardiology outpatient clinic. They were first asked to choose their most preferred, second most preferred, and least preferred persona. Subsequently, they were asked to rate three of the adapted messages; one for every of the persona choices. We created five personas that pertained to five patient clusters. Personas varied mainly on preferences for medical or lay language, current or future temporal perspective, and including or excluding explicit health risks. Fifty-five different adaptation rules were developed, primarily describing adaptations to the message's perspective, level of detail, sentence structure, and terminology. Most participants in the validation study could identify with one of the five personas, although some of them found it hard to choose. On average, 68.5% of all participants rated the messages that matched their most preferred

New mobile technologies such as smartphones facilitate the delivery of brief tailored messages to promote adherence. However, the best approach for tailoring messages is unknown. Persons living with HIV (PLWH might be more receptive to some messages than others based on their current psychological state.Methods: We recruited 37 PLWH from a parent study of motivational states and adherence. Participants completed smartphone-based surveys at a random time every day for 2 weeks, then immediately received intervention or control tailored messages, depending on random assignment. After 2 weeks in the initial condition, participants received the other condition in a crossover design. Intervention messages were tailored to match PLWH’s current psychological state based on five variables – control beliefs, mood, stress, coping, and social support. Control messages were tailored to create a mismatch between message framing and participants’ current psychological state. We evaluated intervention feasibility based on acceptance, ease of use, and usefulness measures. We also used pilot randomized controlled trial methods to test the intervention’s effect on adherence, which was measured using electronic caps that recorded pill-bottle openings.Results: Acceptance was high based on 76% enrollment and 85% satisfaction. Participants found the hardware and software easy to use. However, attrition was high at 59%, and usefulness ratings were slightly lower. The most common complaint was boredom. Unexpectedly, there was no difference between mismatched and matched messages’ effects, but each group showed a 10%–15% improvement

Cellular telephony has become a bright example of co-evolution of human society and information technology. This trend has also been reflected in health care and health promotion projects which included cell phones in data collection and communication chain. While many successful projects have been realized, the review of phone-based data collection techniques reveals that the existing technologies do not completely address health promotion research needs. The paper presents approaches which close this gap by extending existing versatile platforms. The messaging systems are designed for a health-promotion research to prevent obesity and obesity-related health disparities among low-income Latino adolescent girls. Messaging and polling mechanisms are used to communicate and automatically process response data for the target constituency. Preliminary survey data provide an insight on phone availability and technology perception for the study group.

Smartphone apps can provide real-time, tailored interventions for smoking cessation. The current study examines the effectiveness of a smartphone-based smoking cessation application that assessed risk for imminent smoking lapse multiple times per day and provided messages tailored to current smoking lapse risk and specific lapse triggers. Participants (N=59) recruited from a safety-net hospital smoking cessation clinic completed phone-based ecological momentary assessments (EMAs) 5 times/day for 3 consecutive weeks (1week pre-quit, 2weeks post-quit). Risk for smoking lapse was estimated in real-time using a novel weighted lapse risk estimator. With each EMA, participants received messages tailored to current level of risk for imminent smoking lapse and self-reported presence of smoking urge, stress, cigarette availability, and motivation to quit. Generalized linear mixed model analyses determined whether messages tailored to specific lapse risk factors were associated with greater reductions in these triggers than messages not tailored to specific triggers. Overall, messages tailored to smoking urge, cigarette availability, or stress corresponded with greater reductions in those triggers than messages that were not tailored to specific triggers (p's=0.02 to <0.001). Although messages tailored to stress were associated with greater reductions in stress than messages not tailored to stress, the association was non-significant (p=0.892) when only moments of high stress were included in the analysis. Mobile technology can be used to conduct real-time smoking lapse risk assessment and provide tailored treatment content. Findings provide initial evidence that tailored content may impact users' urge to smoke, stress, and cigarette availability. Copyright © 2017 Elsevier Ltd. All rights reserved.

Preventive health care promotes health and prevents disease or injuries by addressing factors that lead to the onset of a disease, and by detecting latent conditions to reduce or halt their progression. Many risk factors for costly and disabling conditions (such as cardiovascular diseases, cancer, diabetes, and chronic respiratory diseases) can be prevented, yet healthcare systems do not make the best use of their available resources to support this process. Mobile phone messaging applications, such as Short Message Service (SMS) and Multimedia Message Service (MMS), could offer a convenient and cost-effective way to support desirable health behaviours for preventive health care. To assess the effects of mobile phone messaging interventions as a mode of delivery for preventive health care, on health status and health behaviour outcomes. We searched: the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2009, Issue 2), MEDLINE (OvidSP) (January 1993 to June 2009), EMBASE (OvidSP) (January 1993 to June 2009), PsycINFO (OvidSP) (January 1993 to June 2009), CINAHL (EbscoHOST) (January 1993 to June 2009), LILACS (January 1993 to June 2009) and African Health Anthology (January 1993 to June 2009).We also reviewed grey literature (including trial registers) and reference lists of articles. We included randomised controlled trials (RCTs), quasi-randomised controlled trials (QRCTs), controlled before-after (CBA) studies, and interrupted time series (ITS) studies with at least three time points before and after the intervention. We included studies using SMS or MMS as a mode of delivery for any type of preventive health care. We only included studies in which it was possible to assess the effects of mobile phone messaging independent of other technologies or interventions. Two review authors independently assessed all studies against the inclusion criteria, with any disagreements resolved by a third review author. Study design features
This article argues that while compliance with disease prevention and control messages should be high given the unique characteristics of this persuasive situation, the data indicate that non compliance is a major social problem. Two communication theories, Language Expectancy Theory and Reinforcement Expectancy Theory, offer promising new conceptualizations of how more compliance can be obtained with health-related messages. Both theories are supported by empirical evidence. Also, ongoing research programs with three psychological predictors (misanthropy, acculturation and sensation-seeking) show promise in providing evidence on how to tailor health-related, compliance-gaining messages to subgroups within the general population.

We investigated whether a thoroughly personalized message (tailored to a person's "Big Five" personality traits) or a message matched to an alternate form of self-schema (ideal self-schema) would be more influential than a self-schema matched message (that has been found to be effective) at marketing responsible drinking. We expected the more thoroughly personalized Big Five matched message to be more effective than the self-schema matched message. However, neither the Big Five message nor the ideal self-schema message was more effective than the actual self-schema message. Therefore, research examining self-schema matching should be pursued rather than more complex Big Five matching.

Outside health care, content tailoring is driven algorithmically using machine learning compared to the rule-based approach used in current implementations of computer-tailored health communication (CTHC) systems. A special class of machine learning systems ("recommender systems") are used to select messages by combining the collective intelligence of their users (ie, the observed and inferred preferences of users as they interact with the system) and their user profiles. However, this approach has not been adequately tested for CTHC. Our aim was to compare, in a randomized experiment, a standard, evidence-based, rule-based CTHC (standard CTHC) to a novel machine learning CTHC: Patient Experience Recommender System for Persuasive Communication Tailoring (PERSPeCT). We hypothesized that PERSPeCT will select messages of higher influence than our standard CTHC system. This standard CTHC was proven effective in motivating smoking cessation in a prior randomized trial of 900 smokers (OR 1.70, 95% CI 1.03-2.81). PERSPeCT is an innovative hybrid machine learning recommender system that selects and sends motivational messages using algorithms that learn from message ratings from 846 previous participants (explicit feedback), and the prior explicit ratings of each individual participant. Current smokers (N=120) aged 18 years or older, English speaking, with Internet access were eligible to participate. These smokers were randomized to receive either PERSPeCT (intervention, n=74) or standard CTHC tailored messages (n=46). The study was conducted between October 2014 and January 2015. By randomization, we compared daily message ratings (mean of smoker ratings each day). At 30 days, we assessed the intervention's perceived influence, 30-day cessation, and changes in readiness to quit from baseline. The proportion of days when smokers agreed/strongly agreed (daily rating ≥4) that the messages influenced them to quit was significantly higher for PERSPeCT (73%, 23/30) than

Embodiments of the invention may be used to manage message queues in a parallel computing environment to prevent message queue deadlock. A direct memory access controller of a compute node may determine when a messaging queue is full. In response, the DMA may generate and interrupt. An interrupt handler may stop the DMA and swap all descriptors from the full messaging queue into a larger queue (or enlarge the original queue). The interrupt handler then restarts the DMA. Alternatively, the interrupt handler stops the DMA, allocates a memory block to hold queue data, and then moves descriptors from the full messaging queue into the allocated memory block. The interrupt handler then restarts the DMA. During a normal messaging advance cycle, a messaging manager attempts to inject the descriptors in the memory block into other messaging queues until the descriptors have all been processed.

Evidence shows that clinical audit and feedback can significantly improve compliance with desired practice, but it is unclear when and how it is effective. Audit and feedback is likely to be more effective when feedback messages can influence barriers to behavior change, but barriers to change differ across individual health-care providers, stemming from differences in providers' individual characteristics. The purpose of this article is to invite debate and direct research attention towards a novel audit and feedback component that could enable interventions to adapt to barriers to behavior change for individual health-care providers: computer-supported tailoring of feedback messages. We argue that, by leveraging available clinical data, theory-informed knowledge about behavior change, and the knowledge of clinical supervisors or peers who deliver feedback messages, a software application that supports feedback message tailoring could improve feedback message relevance for barriers to behavior change, thereby increasing the effectiveness of audit and feedback interventions. We describe a prototype system that supports the provision of tailored feedback messages by generating a menu of graphical and textual messages with associated descriptions of targeted barriers to behavior change. Supervisors could use the menu to select messages based on their awareness of each feedback recipient's specific barriers to behavior change. We anticipate that such a system, if designed appropriately, could guide supervisors towards giving more effective feedback for health-care providers. A foundation of evidence and knowledge in related health research domains supports the development of feedback message tailoring systems for clinical audit and feedback. Creating and evaluating computer-supported feedback tailoring tools is a promising approach to improving the effectiveness of clinical audit and feedback.

To conduct a systematic review of the effect of face-to-face delivered tailored health messages on patient behavior and applications for practice. A systematic literature review and meta-analysis. Systematic searches of a number of electronic databases were conducted and criteria for selection of studies were specified. 6 experimental studies published between 2003 and 2009 were included. The studies were all randomized controlled trials to evaluate the effectiveness of a face-to-face tailored messaging intervention. There were variation in their research design and methods used to randomize. All participants were aged at least 18 years. All of the studies reported positive changes in participants' health behavior with varying degrees of effect size and duration. A meta-analysis of the available data also confirmed an overall positive effect of tailored messaging on participants' health behaviors. The systematic review and the meta-analysis demonstrate a significant and positive effective of face-to-face tailored messaging upon participants' health behaviors. Health practitioners should be encouraged to allot time in their work routines to discover their patients' psycho-social characteristics and felt needs in order that they can provide a tailored health message to enable the patient to adopt health-promoting regimes into their lifestyle.

Dieting prevention interventions have been relatively unsuccessful and may be more effective if they concentrate on messages known to be relatively high on persuasive properties. We aimed to identify anti-dieting messages rated most strongly on persuasive dimensions and participant characteristics that predicted message evaluations in adolescent girls. Grade 7 and 8 girls completed questionnaires assessing risk factors for, and early symptoms of, eating disorders. Two weeks later, participants viewed on video seven messages (each 2-3 minutes long) frequently used to dissuade against dieting in prevention interventions and one control message. After viewing each message, participants rated it on a scale assessing the persuasive dimensions of Relevance, Believability, Emotional Response, and Intention to Diet. A quarter to a third of participants felt less likely to go on a diet after viewing the messages. "Skipping meals makes you feel starved so you overeat and feel bad" and "Don't be fooled by the fad diets promoted in the media" were rated most strongly. Higher dieting, body dissatisfaction, and negative affect were generally associated with lower persuasive ratings, suggesting the importance of intervention prior to the establishment of dieting behaviors after which there is more message resistance. Age was also a predictor of Believability for some messages, supporting the importance of ensuring the age appropriateness of messages.
Perceived anonymity and decreased influence of sexual double standards in tourism provide female travelers with opportunities for sexual experimentation and risk taking. The purpose of this study was (a) to identify the clusters of risk takers among young women based on their perceptions of and motivations for sexual risk taking in tourism and (b) to profile the clusters with respect to the psychological, sexual, demographic, and tourist characteristics. The data were collected through an online survey of 853 women (age in years: M = 23.5, SD = 6.67). Five clusters of sexual risk takers emerged based on their factor-analyzed risk perceptions and motivations. These clusters were interpreted as (a) diversely motivated broad risk perceivers; (b) fun-seeking broad risk perceivers; (c) diversely motivated physical risk perceivers; (d) anonymity- and empowerment-seeking risk disregarders; and (e) unmotivated broad risk perceivers. Women in these clusters differed in their intentions to engage in sexual risk taking in tourism, sensation-seeking propensities, perceptions of tourist characteristics, levels of sexual experience, and demographic backgrounds. Results suggest tailoring sexual health promotion messages based on cluster affiliation, leveraging cluster-specific risk perceptions, motivations, and personal characteristics. This study provides recommendations for individually tailored, context-specific, age-appropriate, and gender-sensitive sexual health education programs.

Patients and methods: Twenty patients with type 2 diabetes (T2DM were recruited from a diabetes health clinic. Participants were segmented using the Descriptor™, a language-based questionnaire, to identify patient types based on their control orientation (internal/external, agency (high/low, and affect (positive/negative, which are well studied constructs related to T2DM self-management. Two of the seven self-care behaviors described by the American Association of Diabetes Educators (healthy eating and taking medication were used to develop standard messages and then linguistically tailored using features of the six different construct segment types of the Descriptor™. A subset of seven participants each provided feedback on their preference for standard or linguistically tailored messages; 12 comparisons between standard and tailored messages were made. Results: Overall, the tailored messages were preferred to the standard messages. When the messages were matched to specific construct segment types, the tailored messages were preferred over the standard messages, although this was not statistically significant. Conclusion: Linguistically tailoring messages based on construct segments is feasible. Furthermore, tailored messages were more often preferred over standard messages. This study provides some preliminary evidence for tailoring messages based on the linguistic features of control orientation, agency, and affect

Among adults with type 2 diabetes mellitus (T2DM), adherence to recommended self-care activities is suboptimal, especially among racial and ethnic minorities with low income. Self-care nonadherence is associated with having worse glycemic control and diabetes complications. Text messaging interventions are improving the self-care of adults with T2DM, but few have been tested with disadvantaged populations. To develop Rapid Education/Encouragement And Communications for Health (REACH), a tailored, text messaging intervention to support the self-care adherence of disadvantaged patients with T2DM, based on the Information-Motivation-Behavioral skills model. We then tested REACH's usability to make improvements before evaluating its effects. We developed REACH's content and functionality using an empirical and theory-based approach, findings from a previously pilot-tested intervention, and the expertise of our interdisciplinary research team. We recruited 36 adults with T2DM from Federally Qualified Health Centers to participate in 1 of 3 rounds of usability testing. For 2 weeks, participants received daily text messages assessing and promoting self-care, including tailored messages addressing users' unique barriers to adherence, and weekly text messages with adherence feedback. We analyzed quantitative and qualitative user feedback and system-collected data to improve REACH. Participants were, on average, 52.4 (SD 9.5) years old, 56% (20/36) female, 63% (22/35) were a racial or ethnic minority, and 67% (22/33) had an income less than US $35,000. About half were taking insulin, and average hemoglobin A1c level was 8.2% (SD 2.2%). We identified issues (eg, user concerns with message phrasing, technical restrictions with responding to assessment messages) and made improvements between testing rounds. Overall, participants favorably rated the ease of understanding (mean 9.6, SD 0.7) and helpfulness (mean 9.3, SD 1.4) of self-care promoting text messages on a scale of 1

Media messages can facilitate the delivery of accurate information related to HIV and sexually transmitted infection. This study's purpose was to examine preexisting media campaigns from the iMPPACS study to assess age-, gender-, and culturally appropriate components identified by African American females who attend historically Black colleges/universities. In 3 separate focus group sessions, 31 Black female college students (M age = 20) viewed 4 vignettes and heard 3 audio-only clips, then ranked and commented on them based on perceived satisfaction with HIV prevention content and appropriateness of delivery. Conventional qualitative analysis using NVivo software was performed until saturation of content was achieved and themes derived. Six major themes emerged and were designated as (a) social media; (b) mirror image; (c) visually dynamic advertisements; (d) the real world; (e) people, place, things; and (f) HIV knowledge. Visually stimulating content (i.e., graphics) was found to be most appealing in marketing HIV prevention, with brief monologue/dialogue from scenarios that resemble daily life. Socially and culturally relevant HIV prevention messages are important to Black college female students. Participants recommended creating short audiovisual messages that encompass familiar contexts like dorm rooms and appealing graphics for HIV health promotion messages, such as emojis. Future audio-only prevention advertisements for this population should use recognizable voices (e.g., celebrities). Finally, messaging should be promoted on open and closed circuit social media platforms.

Young Latino immigrant men who have sex with men (MSM) are at risk for HIV and for delayed diagnosis. A need exists to raise awareness about HIV prevention in this population, including the benefits of timely HIV testing. This project was developed through collaboration between University of WA researchers and Entre Hermanos, a community-based organization serving Latinos. Building from a community-based participatory research approach, the researchers developed a campaign that was executed by Activate Brands, based in Denver, Colorado. The authors (a) describe the development of HIV prevention messages through the integration of previously collected formative data; (b) describe the process of translating these messages into PSAs, including the application of a marketing strategy; (c) describe testing the PSAs within the Latino MSM community; and (c) determine a set of important factors to consider when developing HIV prevention messages for young Latino MSM who do not identify as gay.

Background: Prenatal smoking is a major public health concern and uptake of NHS cessation support is low in this group. Text message-based self-help is a promising intervention for this population but little is known about its likely real-world uptake, an essential parameter for estimating public health impact. Aims were to explore uptake (including cost) of a tailored, theory-guided, text message intervention for pregnant smokers (‘MiQuit’) when offered online. Methods: Links to a website pr...

To identify an effective medium for communicating with adolescents in a large-scale, cost-effective violence prevention program. A set of youth violence prevention programs was established at The Stamford Hospital, a level II trauma center. The traveling version of the program was presented to middle school students in four parts: 1) a rap music video created by our violence prevention staff, 2) a facilitated discussion about dealing with anger, 3) a video of a trauma resuscitation in our emergency department, and 4) a commercial video of a teenage boy paralyzed after a gunshot wound. A written questionnaire with a five-point rating scale (1 to 5) was used to survey the audience 1 month after the program. The survey assessed the respondents' recall of each part of the program and the perceptions of the value of each part in identifying the problem of violence and reducing violent behavior. Of 99 respondents, the highest ratings for retention, problem identification, and impact were given to the commercial video (combined average category ranking of 11.394) and the rap music video (11.182). The trauma resuscitation video and the discussion of anger were ranked as being less effective (10.253 and 9.383, respectively). The audience seemed to comprehend the main point of the program and ranked the program, as a whole, higher than any of the parts when measured by success at problem identification and impact. Effective communication with adolescents is possible through many avenues. Children of the video age respond well to visual material. A violence prevention program should incorporate effective multimedia presentations. A variety of methods in combination proves to be most effective.

Smoking prevalence rates among Dutch children increase rapidly after they transit to secondary school, in particular among children with a low socioeconomic status (SES). Web-based, computer-tailored programs supplemented with prompt messages may be able to empower children to prevent them from starting to smoke when they transit to secondary school. The main aim of this study is to evaluate whether computer-tailored feedback messages, with and without prompt messages, are effective in decreasing children's smoking intentions and smoking behavior after 12 and 25 months of follow-up. Data were gathered at baseline (T0), and after 12 months (T1) and 25 months (T2) of follow-up of a smoking prevention intervention program called Fun without Smokes. A total of 162 schools were randomly allocated to a no-intervention control group, an intervention prompt group, or an intervention no-prompt group. A total of 3213 children aged 10 to 12 years old participated in the study and completed a Web-based questionnaire assessing their smoking intention, smoking behavior, and sociocognitive factors, such as attitude, social influence, and self-efficacy, related to smoking. After completion, children in the intervention groups received computer-tailored feedback messages in their own email inbox and those messages could be accessed on the intervention website. Children in the prompt group received prompt messages, via email and short message service (SMS) text messaging, to stimulate them to reuse the intervention website with nonsmoking content. Multilevel logistic regression analyses were performed using multiple imputations to assess the program effects on smoking intention and smoking behavior at T1 and T2. A total of 3213 children participated in the Fun without Smokes study at T0. Between T0 and T1 a total of 1067 children out of the original 3213 (33.21%) dropped out of the study. Between T0 and T2 the number of children that did not participate in the final measurement was

We investigated whether presenting anti-binge drinking health campaign messages in different message framing and evidence types influences college students' intention to avoid binge drinking, based on prospect theory (PT) and exemplification theory. A 2 (message framing: loss-framed message/gain-framed message) X 2 (evidence type: statistical/narrative) between-subjects factorial design with a control group was conducted with 156 college students. College students who were exposed to the loss-framed message condition exhibited a higher level of intention to avoid binge drinking in the near future than those who did not see any messages (the control group). This finding was mainly among non-binge drinkers. Regardless of evidence type, those who were exposed to the messages exhibited a higher level of intention to avoid binge drinking than those in the control group. This is also mainly among non-binge drinkers. We also found the main effects of message framing and evidence type on attitude toward the message and the main effect of message framing on attitude toward drinking.

To test whether message framing (ie, gain vs. loss) and risk type (ie, health vs appearance risk) in skin cancer prevention messages interact with one's prior experience. Two experiments with a 2 (message framing: gain vs loss) × 2 (risk type: health vs appearance risk) factorial design were conducted. The participants were given a URL to the experiment website via e-mail. On the first page of the website, the participants were told that they would be asked to evaluate a skin cancer print public service announcement (PSA): Online experiments. A total of 397 individuals participated (236 for experiment 1 and 161 for experiment 2). Apparatus: Four versions of the skin cancer print PSAs were developed. Four PSAs were identical except for the 2 manipulated components: message framing and risk type. Measures were adopted from Cho and Boster (message framing), Jones and Leary and Kiene et al. (risk type), De Vries, Mesters, van't Riet, Willems, and Reubsaet and Knight, Kirincich, Farmer, and Hood (prior experience), and Hammond, Fong, Zanna, Thrasher, and Borland and Hoffner and Ye (behavioral intent). General linear models were used to test hypotheses. Three-way interactions among message framing, risk type, and prior experience were found: When the intent of the message was to encourage sunscreen use, the effects of message framing and risk type were shown to be the exact opposite directions from when the intent was to discourage indoor/outdoor tanning. To discourage tanning among those with prior experience, messages emphasizing losses in terms of one's health will work better. For those with no prior experience, messages emphasizing potential appearance losses will work better for discouraging tanning while messages emphasizing gains like improving appearance will do a better job in encouraging sunscreen use.

Embodiments of the invention may be used to manage message queues in a parallel computing environment to prevent message queue deadlock. A direct memory access controller of a compute node may determine when a messaging queue is full. In response, the DMA may generate an interrupt. An interrupt handler may stop the DMA and swap all descriptors from the full messaging queue into a larger queue (or enlarge the original queue). The interrupt handler then restarts the DMA. Alternatively, the interrupt handler stops the DMA, allocates a memory block to hold queue data, and then moves descriptors from the full messaging queue into the allocated memory block. The interrupt handler then restarts the DMA. During a normal messaging advance cycle, a messaging manager attempts to inject the descriptors in the memory block into other messaging queues until the descriptors have all been processed.

Because adolescent girls are being targeted on social networking sites by the tobacco industry, new online tobacco control (TC) initiatives are needed. The purpose of this interpretive descriptive study was to explore adolescent girls' perspectives on the use of social networking sites to deliver TC messages targeting young women. Focus groups were conducted with 17 girls aged 16 to 19. Seven TC messages were provided for evaluation and as context for discussion about the delivery of TC messages on social networking sites. Data were analyzed for themes, which included concerns about the effectiveness of current TC messages and the stereotypical representations of gender, factors perceived to influence the effectiveness of TC messages on social networking sites, and suggestions for enhancing the effectiveness of TC messages placed on social networking sites. Endorsement of TC messaging on social networking sites suggests that this medium is an untapped resource for smoking prevention.

This article describes the contents of an interactive computer-tailored program. The program is based on previous studies of the practice of care for persons with Prader-Willi syndrome. This genetic condition is associated with a constant overeating behaviour with the risk of obesity. The aim of the program is to start a process of awareness, reflection, and discussion by caregivers who are confronted with the moral dilemma of respect for autonomy versus restricting overeating behaviour. The program focuses on values (such as health and well-being) that are relevant to caregivers in daily practice. Furthermore, the focus is on various ways of interaction with the client. Caregivers were expected to focus mainly on health, and on both paternalistic and interpretive/deliberative forms of interaction. Sixteen professionals and 12 parents pilot-tested the program contents. With a pre-test, responses on one central case were collected for tailored feedback; with a post-test, the effects of the program were measured. Significant correlations were found between the values of autonomy and consultation and between autonomy and well-being. In contrast to our expectations respondents valued all categories (autonomy, consultation, health, well-being, and liveability for others) as equally important in the pre-test. No significant changes in scores were found between pre- and post-test. The open answers and remarks of participants support the program contents. Participants' responses support previous research findings, advocating a concept of autonomy in terms of positive freedom, through support by others. The promotion of the client's self-understanding and self-development is central in this concept.

Antitobacco groups have joined millions of other commercial or noncommercial entities in developing a presence on the Web. These groups primarily represent the following different sponsorship categories: grassroots, medical, government, and corporate. To obtain a better understanding of the strengths and weaknesses in the message design of antitobacco Web sites, this project analyzed 100 antitobacco Web sites ranging across these four sponsorship categories. The results show that the tobacco industry sites posted just enough antismoking information to appease the antismoking publics. Medical organizations designed their Web sites as specialty sites and offered mostly scientific information. While the government sites resembled a clearinghouse for antitobacco related information, the grassroots sites represented the true advocacy outlets. In general, the industry sites provided the weakest persuasive messages and medical sites fared only slightly better. Government and grassroots sites rated most highly in presenting their antitobacco campaign messages on the Web.
In Brazil, alternative religious approaches are being used to spread the message of AIDs prevention. The concepts and practices of traditional Afro--Brazilian religion are being used in a newly released booklet for religious leaders of Candomble, a traditional spirit cult that traces its origins to the Yoruba of western Africa. There is a fusion of this spirit cult with Catholicism. The practice of all night dancing ceremonies where initiates appeal to orixas for guidance is coupled with private daily obligations. Orixas offer to cure the spirit and the body and are often used after Western medicine has failed to provide a cure. Candomble and Umbanda are the most widely observed religions in Brazil. There is a saying that everyone in Brazil is Catholic, but believers in Afro-Brazilian religion. Catholic parishes account for 19,000 places of worship throughout the country, but in 3 of the largest states, excluding the most "African" state Bahia, there are 55,000 Afro--Brazilian religious centers. 30,000 are in Rio de Janeiro, 16,00 in Sao Paulo, and 11,700 in Rio Grande do Sul. Although these religious centers are part of Brazilian identity and culture, government officials and the Catholic Church have repressed or looked unfavorably upon them. The group, Religious Support Against AIDS (ARCA), sponsored by the Institute for Religious Studies, provides education and consciousness raising through religious and social activities. ARCA hosted a meeting with Candomble religious leaders in May 1989 to explore options for dealing with AIDs, since their contact was with the poorer segments of the population and they possessed knowledge of traditional cures and medicinal plants. The meeting was successful, and ARCA was asked to provide educational materials. The problem was that ceremonial, rites were private and an AIDs stigma might emerge among the priests and priestesses, who were thought to be mainly homosexuals.

Mobile populations are at increased risk for HIV infection. Exposure to HIV prevention messages at all phases of the migration process may help decrease im/migrants’ HIV risk. We investigated levels of exposure to HIV prevention messages, factors associated with message exposure, and the association between exposure to prevention messages and HIV testing behavior among Mexican im/migrants at different phases of the migration process. We conducted a cross-sectional, probability survey of Mexican im/migrants (N=3,149) traveling through the border city of Tijuana, Mexico. The results indicate limited exposure to prevention messages (57%–75%) and suboptimal last 12-month HIV testing rates (14%–25%) across five migration phases. Compared to pre-departure levels (75%), exposure to messages decreases at all post-departure migration phases (57%–63%, pprevention messages is positively associated with greater odds of HIV testing at the pre-departure, destination, and interception phases. Binational efforts need to be intensified to reach and deliver HIV prevention to Mexican im/migrants across the migration continuum. PMID:26595267

Smoking in pregnancy is a major public health concern. Pregnant smokers are particularly difficult to reach, with low uptake of support options and few effective interventions. Text message-based self-help is a promising, low-cost intervention for this population, but its real-world uptake is largely unknown. The objective of this study was to explore the uptake and cost-effectiveness of a tailored, theory-guided, text message intervention for pregnant smokers ("MiQuit") when advertised on the internet. Links to a website providing MiQuit initiation information (texting a short code) were advertised on a cost-per-click basis on 2 websites (Google Search and Facebook; £1000 budget each) and free of charge within smoking-in-pregnancy webpages on 2 noncommercial websites (National Childbirth Trust and NHS Choices). Daily budgets were capped to allow the Google and Facebook adverts to run for 1 and 3 months, respectively. We recorded the number of times adverts were shown and clicked on, the number of MiQuit initiations, the characteristics of those initiating MiQuit, and whether support was discontinued prematurely. For the commercial adverts, we calculated the cost per initiation and, using quit rates obtained from an earlier clinical trial, estimated the cost per additional quitter. With equal capped budgets, there were 812 and 1889 advert clicks to the MiQuit website from Google (search-based) and Facebook (banner) adverts, respectively. MiQuit was initiated by 5.2% (42/812) of those clicking via Google (95% CI 3.9%-6.9%) and 2.22% (42/1889) of those clicking via Facebook (95% CI 1.65%-2.99%). Adverts on noncommercial webpages generated 53 clicks over 6 months, with 9 initiations (9/53, 17%; 95% CI 9%-30%). For the commercial websites combined, mean cost per initiation was £24.73; estimated cost per additional quitter, including text delivery costs, was £735.86 (95% CI £227.66-£5223.93). Those initiating MiQuit via Google were typically very early in pregnancy

African American girls are at a greater risk of obesity than their nonminority peers. Parents have the primary control over the home environment and play an important role in the child obesity prevention. Obesity prevention programs to help parents develop an obesity-preventive home environment are needed. The purpose of this study was to collect formative research from parents of 8-10-year old African American girls about perceptions, expectations, and content for a text messaging based program. Mothers ( n = 30) participated in surveys and interviews to inform message development and content. A professional expert panel ( n = 10) reviewed draft text messages via a survey. All the mothers reported owning a cellphone with an unlimited texting plan, and they used their cellphones for texting (90.0%) and accessing the Internet (100.0%). The majority were interested in receiving text messages about healthy eating and physical activity (86.7%). Interviews confirmed survey findings. One hundred and seven text messages promoting an obesity-preventive home environment were developed. The expert panel and parents reported positive reactions to draft text messages. This research provides evidence that mobile health (mHealth) interventions appeal to parents of African American girls and they have ready access to the technology with which to support this approach.

Adolescent girls and young women who are at risk for unplanned pregnancy and sexually transmitted infection (STI), including HIV, are frequently counseled to use a hormonal contraceptive to protect against the former and condoms to protect against the latter, for example, American College of Obstetricians and Gynecologists, 2011. The present paper reviews the literature on multiple risk messages, compliance with this dual-use recommendation, predictors of dual use, and interventions developed to encourage dual use. Data indicate that simultaneous use of these two methods is not common, and that efforts to encourage dual use have not yielded promising results. An alternative is to recommend condom use alone, since condoms protect very well against STI and HIV, and quite well against pregnancy when used consistently and correctly. The availability of emergency contraception is relevant here. Research utilizing a randomized controlled trial is recommended.

Search engines are increasingly used to seek suicide-related information online, which can serve both harmful and helpful purposes. Google acknowledges this fact and presents a suicide-prevention result for particular search terms. Unfortunately, the result is only presented to a limited number of visitors. Hence, Google is missing the opportunity to provide help to vulnerable people. We propose a two-step approach to a tailored optimization: First, research will identify the risk factors. Second, search engines will reweight algorithms according to the risk factors. In this study, we show that the query share of the search term "poisoning" on Google shows substantial peaks corresponding to peaks in actual suicidal behavior. Accordingly, thresholds for showing the suicide-prevention result should be set to the lowest levels during the spring, on Sundays and Mondays, on New Year's Day, and on Saturdays following Thanksgiving. Search engines can help to save lives globally by utilizing a more tailored approach to suicide prevention.

Preventing family violence requires that stakeholders and the broader public be involved in developing evidence-based violence prevention strategies. However, gaps exist in between what we know (knowledge), what we do (action), and the structures supporting practice (policy). We discuss the broad challenge of mobilizing knowledge-for-action in family violence, with a primary focus on the issue of how stakeholders and the public can be effectively engaged when developing and communicating evidence-based violence prevention messages. We suggest that a comprehensive approach to stakeholder and public engagement in developing violence prevention messages includes: 1) clear and consistent messaging; 2) identifying and using, as appropriate, lessons from campaigns that show evidence of reducing specific types of violence; and 3) evidence-informed approaches for communicating to specific groups. Components of a comprehensive approach must take into account the available research evidence, implementation feasibility, and the context-specific nature of family violence. While strategies exist for engaging stakeholders and the public in messaging about family violence prevention, knowledge mobilization must be informed by evidence, dialogue with stakeholders, and proactive media strategies. This paper will be of interest to public health practitioners or others involved in planning and implementing violence prevention programs because it highlights what is known about the issue, potential solutions, and implementation considerations.
Disengagement beliefs function to reduce cognitive dissonance and a number of predictions with regard to disengagement beliefs have been tested and verified. However, the influence of disengagement beliefs on persuasion has not been studied yet. In a field-experiment, 254 smokers were randomly assigned to a persuasive message condition or a no-information control condition. First, it was assessed to what extent disengagement beliefs influenced persuasion. In smokers with low adherence to disengagement beliefs, quitting activity (attempting to quit) in the control condition was high, but this was not further increased by persuasive information on the negative outcomes of smoking. In contrast, smokers who strongly adhered to disengagement beliefs showed low quitting activity in the control condition, but significantly more quitting activity when they received the persuasive message. Second, it was studied what smokers do when they experience negative affect caused by the persuasive message. The results show that in smokers who strongly adhered to disengagement beliefs, negative affect was associated with less quitting activity. Although these results show that quitting activity as assessed at 2 and 8 months follow-ups was influenced by disengagement beliefs, point prevalence seven-day quitting was not. This study shows that adherence to disengagement beliefs is a relevant individual difference in understanding effects of smoking cessation interventions.

Falls are very common in older persons and can result in substantial disability and distress. By undertaking strength and balance training (SBT) exercises, older people can reduce their risk of falling. The Internet offers a potentially cost-effective means of disseminating information about SBT to older people and their carers. A particular advantage of using the Internet for this purpose is that the advice given can be 'tailored' to the needs of the individual. This study used a randomized controlled design to evaluate an interactive web-based program that tailored advice about undertaking SBT activities. The participants were 280 people with an age range of 65-97 years recruited by advertising the website by email and the Internet. Those randomized to the tailored advice were presented with advice tailored to their personal self-rated balance capabilities, health problems and activity preferences. Those in the control group were presented with all the advice from which the tailored advice was selected. After reading the advice, those in the tailored advice group (n = 144) had more positive attitudes (p < 0.01) than those in the control group (n = 136), reporting greater perceived relevance of the SBT activities, greater confidence in the ability to carry them out, and hence stronger intentions to undertake the activities. This study provides an initial indication that an interactive website might offer a cost-effective way to provide personalized advice to some older people. Further research is required to determine whether website-based advice on falls prevention changes behavior as well as intentions and whether the advice needs to be supplemented by other forms of support.

Suicidal behaviour and deliberate self-harm are common among adults. Research indicates that maintaining contact either via letter or postcard with at-risk adults following discharge from care services can reduce reattempt risk. Feasibility trials demonstrated that intervention through text message was also effective in preventing suicide repetition amongst suicide attempters. The aim of the current study is to investigate the effect of text message intervention versus traditional treatment on reducing the risk of suicide attempt repetition among adults after self-harm. The study will be a 2-year multicentric randomized controlled trial conducted by the Brest University Hospital, France. Participants will be adults discharged after self-harm, from emergency services or after a short hospitalization. Participants will be recruited over a 12-month period. The intervention is comprised of an SMS that will be sent at h48, D7, D15 and monthly. The text message enquires about the patients' well-being and includes information regarding individual sources of help and evidence-based self help strategies. Participants will be assessed at the baseline, month 6 and 13. As primary endpoint, we will assess the number of patients who reattempt suicide in each group at 6 months. As secondary endpoints, we will assess the number of patients who reattempt suicide at 13 month, the number of suicide attempts in the intervention and control groups at 6 and 13 month, the number of death by suicide in the intervention and control groups at month 6 and 13. In both groups, suicidal ideations, will be assessed at the baseline, month 6 and 13. Medical costs and satisfaction will be assessed at month 13. This paper describes the design and deployment of a trial SIAM; an easily reproducible intervention that aims to reduce suicide risk in adults after self-harm. It utilizes several characteristics of interventions that have shown a significant reduction in the number of suicide reattempts. We
Full Text Available Abstract Background Our objective was to examine factors associated with distributive injection equipment sharing and how needle exchange programs (NEPs can help reduce distributive sharing among injection drug users (IDUs. Methods 145 English speaking Canadian IDUs ages 16 years and over who had injected in the past 30 days were recruited for a cross-sectional survey. Participants were asked about their socio-demographic characteristics, HIV risk behaviours, social support, drug treatment readiness, program satisfaction, health and social service use and NEP drug use. Bivariate statistics and logistic regression were used to characterize the population and examine correlates of sharing behaviour. Results More IDUs reported distributive sharing of cookers (45% than needles (36% or other types of equipment (water 36%; filters 29%; swabs 8%. Regression analyses revealed the following factors associated with distributing used cookers: a history of cocaine/crack injection, an Addiction Severity Index (ASI score indicative of a mental health problem, and older than 30 years of age. Factors associated with giving away used water included: male, injected methadone, injected other stimulants and moved 3+ times in the past 6 months. Factors associated with giving away used filters included: injected cocaine/crack or stayed overnight on the street or other public place. Factors associated with giving away swabs included: an ASI mental health score indicative of a mental health problem, and HCV negative status. Conclusions Our findings show that more IDUs give away cookers than needles or other injection equipment. While the results showed that correlates of sharing differed by piece of equipment, each point to distributive sharing by the most marginalized IDUs. Targeting prevention efforts to reduce equipment sharing in general, and cookers in particular is warranted to reduce use of contaminated equipment and viral transmission.

To gain better understanding of (i) beliefs and knowledge about stroke; (ii) attitudes about walking for stroke prevention; and (iii) barriers and facilitators to walking among Korean seniors for the cultural tailoring of a stroke prevention walking programme. Physical inactivity is a major risk factor for stroke. Korean immigrant seniors are one of the most sedentary ethnic groups in the United States. An explorative study using focus group data. Twenty-nine Korean immigrant seniors (64-90 years of age) who had been told by a doctor at least once that their blood pressure was elevated participated in 3 focus groups. Each focus group consisted of 8-11 participants. Focus group audiotapes were transcribed and analysed using standard content analysis methods. Participants identified physical and psychological imbalances (e.g. too much work and stress) as the primary causes of stroke. Restoring 'balance' was identified as a powerful means of stroke prevention. A subset of participants expressed that prevention may be beyond human control. Overall, participants acknowledged the importance of walking for stroke prevention, but described barriers such as lack of personal motivation and unsafe environment. Many participants believed that providing opportunities for socialisation while walking and combining walking with health information sessions would facilitate participation in and maintenance of a walking programme. Korean immigrant seniors believe strongly that imbalance is a primary cause of stroke. Restoring balance as a way to prevent stroke is culturally special among Koreans and provides a conceptual base in culturally tailoring our stroke prevention walking intervention for Korean immigrant seniors. A stroke prevention walking programme for Korean immigrant seniors may have greater impact by addressing beliefs about stroke causes and prevention such as physical and psychological imbalances and the importance of maintaining emotional well-being. © 2016 John

This study tested the effect of humor in one particular type of print advertisement: the preventive health ads for three topics (alcohol, tobacco, obesity). Previous research using commercial ads demonstrated that individuals' attention is spontaneously attracted by humor, leading to a memory advantage for humorous information over nonhumorous information. Two experiments investigated whether the positive effect of humor can occur with preventive health ads. In Experiment 1, participants observed humorous and nonhumorous health ads while their viewing times were recorded. In Experiment 2, to compare humorous and nonhumorous ads, the memory of health messages was assessed through a recognition task and a convincing score was collected. The results confirmed that, compared to nonhumorous health ads, those using humor received prolonged attention, were judged more convincing, and their messages were better recognized. Overall, these findings suggest that humor can be of use in preventive health communication.

The changes in Washington State and Colorado marijuana laws call for the development of new brief family-focused adolescent marijuana use preventive interventions that are relevant for and tailored to the context of legalization for retail sale. To that end, focus groups with parents and teens were conducted to find out about their concerns and needs in the context of legalization. Six semi-structured focus groups (3 with parents, 3 with teens) were conducted in Washington State in 2013 related to consequences of teen marijuana use and messages that would be effective in helping to prevent teens from using marijuana in the context of legal adult use. A total of 33 teens and 35 parents participated. Three primary themes were common to these parents and teens: the negative consequences of marijuana use during adolescence on mental, physical, and social health; the need for more or better information; and the need for information/messages to come from trusted sources. The themes related to potential prevention messages include the use of fear; stories about real people; focusing on short-term consequences; and teens needing alternative activities (something better to do). The results suggest that parents and teens need information about the new retail marijuana legalization law. Teens are open to both information and guidance from parents as long as it is calm and respectful. Firsthand accounts of consequences of marijuana use from peers and adults, rather than threats from authority figures, could hold some promise for persuading teens to avoid marijuana use.

Latino adolescents are at elevated risk for depression and suicide compared to other ethnic groups. Project goals were to gain insight from community leaders about depression risk factors particular to Latino adolescents and generate innovative suggestions to improve cultural relevance of prevention interventions. This project utilized a CBPR approach to enhance cultural relevance, acceptability, and utility of the findings and subsequent program development. Two focus groups of youth and youth-involved Latino community leaders (n = 18) yielded three overarching themes crucial to a culturally tailored depression prevention intervention: (1) utilize a multipronged and sustainable intervention approach, (2) raise awareness about depression in culturally meaningful ways, and (3) promote Latino youth's social connection and cultural enrichment activities. Findings suggest that both adaptation of existing prevention programs and development of hybrid approaches may be necessary to reduce depression/suicide disparities for Latino youth. One such hybrid program informed by community stakeholders is described.

To estimate the effectiveness of pregnancy smoking cessation support delivered by short message service (SMS) text message and key parameters needed to plan a definitive trial. Multi-centre, parallel-group, single-blinded, individual randomized controlled trial. Sixteen antenatal clinics in England. Four hundred and seven participants were randomized to the intervention (n = 203) or usual care (n = 204). Eligible women were smoked at least one daily cigarette (> 5 pre-pregnancy), were able to receive and understand English SMS texts and were not already using text-based cessation support. All participants received a smoking cessation leaflet; intervention participants also received a 12-week programme of individually tailored, automated, interactive, self-help smoking cessation text messages (MiQuit). Seven smoking outcomes, including validated continuous abstinence from 4 weeks post-randomization until 36 weeks gestation, design parameters for a future trial and cost-per-quitter. Using the validated, continuous abstinence outcome, 5.4% (11 of 203) of MiQuit participants were abstinent versus 2.0% (four of 204) of usual care participants [odds ratio (OR) = 2.7, 95% confidence interval (CI) = 0.93-9.35]. The Bayes factor for this outcome was 2.23. Completeness of follow-up at 36 weeks gestation was similar in both groups; provision of self-report smoking data was 64% (MiQuit) and 65% (usual care) and abstinence validation rates were 56% (MiQuit) and 61% (usual care). The incremental cost-per-quitter was £133.53 (95% CI = -£395.78 to 843.62). There was some evidence, although not conclusive, that a text-messaging programme may increase cessation rates in pregnant smokers when provided alongside routine NHS cessation care. © 2017 The Authors.

Full Text Available Background: As with many low-income countries, diabetes is an increasing issue in Bangladesh affecting an estimated 20% to 30% of the population either as intermediate hyperglycaemia or fully expressed diabetes mellitus (Bhowmik et al., 2012. The Bangladesh D-MAGIC project is a cluster randomised control trial to test the effectiveness of interventions to improve detection, management and control of diabetes in rural Bangladesh. One of these interventions is an mHealth intervention, which involves sending health promotion voice messages to individuals’ mobile phones to target diabetes prevention and management. In-depth formative research (interviews and focus group discussions has been undertaken in rural Faridpur District in order to gain a greater understanding of people’s beliefs, practices and behaviour regarding diabetes prevention and control and their access to and use of mobile phones. The findings of the research, used within the COM-B framework (Michie et al 2011, are being used to inform and appropriately tailor the voice messages to the needs of the target population. This presentation will highlight key findings of the formative research and discuss how these findings are being used to design the mHealth intervention. Aim: To identify key issues for the content and delivery of voice messages regarding the prevention and control of diabetes in rural Bangladesh through in-depth formative research. Methods: We conducted sixteen semi-structured interviews with purposively sampled diabetics, non-diabetics and health professionals. In addition, nine focus group discussions with diabetics and non-diabetics were conducted in villages in three sub-districts of Faridpur. We explored beliefs and behaviour regarding diet, exercise, smoking, stress and care-seeking. The findings from the interviews and focus group discussions were analysed thematically, and specific enablers and barriers to behaviour change related to diabetes identified

Social media is increasingly being used by young people for health-related issues, including communicating about suicide. Due to the concerns about causing distress or inducing suicidal thoughts or behaviors, to date young people neither have been engaged in the development of social media-based suicide prevention interventions nor have interventions focused on educating young people about safe ways to communicate about suicide online. Given the potential that social media holds to deliver messages to vast numbers of people across space and time and the fact that young people often prefer to seek help from their friends and peers, safely educating and engaging young people to develop suicide prevention messages that can be delivered via social media is an obvious next step. The objectives of this study were to (1) provide education to a small number of secondary school students about safe ways to communicate about suicide via social media; (2) engage the same young people in the development of a suite of social media-based suicide prevention multimedia messages; (3) assess the impact of this on participants; and (4) assess the acceptability and safety of the messages developed. This study involved two phases. In phase 1, 20 participants recruited from two schools took part in an 8- to 10-week program during which they were provided with psychoeducation about mental health and suicide, including how to talk safely about suicide online, and they were then supported to design and develop their own media messages. These participants completed an evaluation questionnaire at the conclusion of the program. In phase 2, a larger group of participants (n=69), recruited via an opt-in process, viewed the media messages and completed a short questionnaire about each one. Participants in phase 1 enjoyed the program and reported that they learned new skills, such as how to talk safely about suicide online, and felt more able to provide emotional support to others (16/20, 80%).

A decreased incidence of delirium following the application of non-pharmacologic intervention protocols to several patient populations has been previously reported. However, few studies have been conducted to examine the effects of their application to intensive care unit (ICU) patients. To examine the effects of applying a tailored delirium preventive protocol, developed by the authors, to ICU patients by analyzing its effects on delirium incidence, in-hospital mortality, ICU readmission, and length of ICU stay in a Korean hospital. A single-blind randomized controlled trial. A 1049-bed general hospital with a 105-bed ICU. Sixty and 63 ICU patients were randomly assigned to the intervention and control groups, respectively. The researchers applied the delirium prevention protocol to the intervention group every day for the first 7 days of ICU hospitalization. Delirium incidence, mortality, and re-admission to the ICU during the same hospitalization period were analyzed by logistic regression analysis; the 7- and 30-day in-hospital mortality by Kaplan-Meier survival and Cox proportional hazard regression analysis; and length of ICU stay was assessed by linear regression analysis. Application of the protocol had no significant effect on delirium incidence, in-hospital mortality, re-admission to the ICU, or length of ICU stay. Whereas the risk of 30-day in-hospital mortality was not significantly lower in the intervention than in the control group (OR: 0.33; 95% CI: 0.10-1.09), we found a significantly decreased 7-day in-hospital mortality in the intervention group after protocol application (HR: 0.09; 95% CI: 0.01-0.72). Application of a tailored delirium prevention protocol to acute stage patients during the first 7 days of ICU hospitalization appeared to reduce the 7-day in-hospital risk of mortality only for this patient population.

We explored the effects of linguistic agency assignment on the persuasive impact of a fictitious medical journal editorial about Type 2 diabetes. Participants (N = 422) read 1 of 4 versions of an editorial that differed in the language used to describe the health threat posed by the disease (threat agency) and to outline a program for preventing it (prevention agency). Threat agency was assigned either to the disease (e.g., diabetes puts individuals' lives at risk) or to humans (e.g., individuals who acquire diabetes put their lives at risk). Prevention agency was assigned either to the recommended prevention behaviors (e.g., a healthy diet and regular exercise protect children from Type 2) or to humans (e.g., children who eat a healthy diet and exercise regularly protect themselves from Type 2). Respondents' perceptions of disease severity were higher when threat agency was assigned to diabetes rather than humans. However, attitudes toward the proposed prevention program were higher when prevention agency was assigned to humans rather than to the recommended behaviors. The latter finding contrasts with agency effects observed in previous research on a viral threat, suggesting that the optimal pattern of agency assignment in prevention messaging may be different for acute and chronic lifestyle diseases.

Rates of drug use among sexual-minority youths are disproportionately high. Yet, expressly designed prevention programs targeting this population are absent. This study developed and tested a web-based drug abuse prevention program for sexual-minority youths. A sample (N = 236) of sexual-minority youths was recruited via Facebook. Online, all youths completed pretests; youths randomly assigned to the intervention received a 3-session prevention program; and all youths completed posttest and 3-month follow-up measurements. At 3-month follow-up and compared to youths in the control arm, intervention-arm youths reported less stress, reduced peer drug use, lower rates of past 30-day other drug use, and higher coping, problem solving, and drug-use refusal skills. Outcome data suggest the potential of tailored intervention content to address sexual-minority youths' drug use rates and related risk factors. Moreover, study procedures lend support to the feasibility of using the Internet to recruit sexual-minority youths, collect data, and deliver intervention.

The effectiveness of mobile technology to improve medication adherence via customized Short Messaging Service (SMS) reminders for stroke has not been tested in resource poor areas. We designed a randomized controlled trial to test the effectiveness of SMS on improving medication adherence in stroke survivors in Pakistan. This was a parallel group, assessor-blinded, randomized, controlled, superiority trial. Participants were centrally randomized in fixed block sizes. Adult participants on multiple medications with access to a cell phone and stroke at least 4 weeks from onset (Onset as defined by last seen normal) were eligible. The intervention group, in addition to usual care, received reminder SMS for 2 months that contained a) Personalized, prescription tailored daily medication reminder(s) b) Twice weekly health information SMS. The Health Belief Model and Social Cognitive theory were used to design the language and content of messages. Frontline SMS software was used for SMS delivery. Medication adherence was self-reported and measured on the validated Urdu version of Morisky Medication Adherence Questionnaire. Multiple linear regression was used to model the outcome against intervention and other covariates. Analysis was conducted by intention-to-treat principle. Two hundred participants were enrolled. 38 participants were lost to follow-up. After 2 months, the mean medication score was 7.4 (95 % CI: 7.2-7.6) in the intervention group while 6.7 (95 % CI: 6.4-7.02) in the control group. The adjusted mean difference (Δ) was 0.54 (95 % CI: 0.22-0.85). The mean diastolic blood pressure in the intervention group was 2.6 mmHg (95 % CI; -5.5 to 0.15) lower compared to the usual care group. A short intervention of customized SMS can improve medication adherence and effect stroke risk factors like diastolic blood pressure in stroke survivors with complex medication regimens living in resource poor areas.

Full Text Available Understanding the context of suicidal behaviors is critical for effective suicide prevention strategies. Although suicide is an important topic for Asian Americans, there is limited information about what Asian Americans’ attitudes are towards suicide and their perceptions about the effectiveness of prevention efforts. These questions are critical to examine to provide foundational knowledge for determining how best to intervene. In this study, Asian American (n = 87 and White (n = 87 participants completed self-report indexes on their knowledge of depression and suicide (e.g., estimates of suicide rates, coping attitudes (e.g., help-seeking and suicide prevention attitudes (e.g., usefulness of PSAs. The results indicate that in comparison to Whites, Asian Americans perceived suicidal behavior to be more common, perceived a stronger link between depression and suicide, less frequently endorsed help-seeking strategies, and reported more concern or distress after viewing a suicide prevention PSA. These preliminary results also suggest the possibility of cultural differences in perceptions of suicide prevention messages. The implications of these findings are discussed with a focus on providing recommendations for exploring suicide prevention efforts for Asian Americans.

The purpose was to conduct focus groups with Hispanic employees to obtain input into adaptation of previous DSME interventions for use as a workplace diabetes prevention program. From a list of interested Hispanic employees who attended a local health fair (n = 68), 36 were randomly selected to participate in focus groups held during supper mealtime breaks. An experienced bilingual moderator directed the sessions, using interview guidelines developed by the research team. Participants' ages ranged from 22 to 65 years (mean = 50.4, n = 36, SD = 10.7), 7 males and 29 females attended, and 53% had type 2 diabetes mellitus (T2DM). Employees expressed a keen interest in diabetes classes and recommended a focus on preparing healthier Hispanic foods. Primary barriers to promoting healthier lifestyles were work schedules; many employees worked 2 part-time or full-time jobs. Administrators and direct supervisors of the employees were highly supportive of a workplace diabetes prevention program. The consistent message was that a workplace program would be the ideal solution for Hispanic employees to learn about diabetes and healthy behaviors, given their busy schedules, family responsibilities, and limited resources. If found to be effective, such a workplace program would be generalizable to other service employees who have disproportionate diabetes rates. © 2015 The Author(s).

The last decade has witnessed unprecedented growth in the number of mobile phones in the developing world, thus linking millions of previously unconnected people. The ubiquity of mobile phones, which allow for short message service (SMS), provides new and innovative opportunities for disease prevention efforts. The aim of this review was to describe the characteristics and outcomes of SMS interventions for disease prevention in developing countries and provide recommendations for future work. A systematic search of peer-reviewed and gray literature was performed for papers published in English, French, and German before May 2011 that describe SMS applications for disease prevention in developing countries. A total of 34 SMS applications were described, among which 5 had findings of an evaluation reported. The majority of SMS applications were pilot projects in various levels of sophistication; nearly all came from gray literature sources. Many applications were initiated by the project with modes of intervention varying between one-way or two-way communication, with or without incentives, and with educative games. Evaluated interventions were well accepted by the beneficiaries. The primary barriers identified were language, timing of messages, mobile network fluctuations, lack of financial incentives, data privacy, and mobile phone turnover. This review illustrates that while many SMS applications for disease prevention exist, few have been evaluated. The dearth of peer-reviewed studies and the limited evidence found in this systematic review highlight the need for high-quality efficacy studies examining behavioral, social, and economic outcomes of SMS applications and mobile phone interventions aimed to promote health in developing country contexts.

This study examined the effects of message frames when they were culturally tailored. Focusing on one aspect of culture-individualism and collectivism-the study discovered some similar patterns across cultures: The effect of message framing in motivating preventive behaviors could be moderated by the cultural values embedded in the messages. Messages focusing on individualistic gains and collectivistic losses successfully increased people's intention to adopt preventive behaviors. Practical and theoretical implications are discussed.

The impending public health impact of Alzheimer's disease is tremendous. Physical activity is a promising intervention for preventing and managing Alzheimer's disease. However, there is a lack of evidence-based public health messaging to support this position. This paper describes the application of the Appraisal of Guidelines Research and Evaluation II (AGREE-II) principles to formulate an evidence-based message to promote physical activity for the purposes of preventing and managing Alzheimer's disease. A messaging statement was developed using the AGREE-II instrument as guidance. Methods included (a) conducting a systematic review of reviews summarizing research on physical activity to prevent and manage Alzheimer's disease, and (b) engaging stakeholders to deliberate the evidence and formulate the messaging statement. The evidence base consisted of seven systematic reviews focused on Alzheimer's disease prevention and 20 reviews focused on symptom management. Virtually all of the reviews of symptom management conflated patients with Alzheimer's disease and patients with other dementias, and this limitation was reflected in the second part of the messaging statement. After deliberating the evidence base, an expert panel achieved consensus on the following statement: "Regular participation in physical activity is associated with a reduced risk of developing Alzheimer's disease. Among older adults with Alzheimer's disease and other dementias, regular physical activity can improve performance of activities of daily living and mobility, and may improve general cognition and balance." The statement was rated favourably by a sample of older adults and physicians who treat Alzheimer's disease patients in terms of its appropriateness, utility, and clarity. Public health and other organizations that promote physical activity, health and well-being to older adults are encouraged to use the evidence-based statement in their programs and resources.

Signaling System No. 7 (SS7) is designed to provide a connection-less transfer of signaling messages of reasonable length. Customers having access to user signaling bearer capabilities as specified in the ANSI T1.623 and CCITT Q.931 standards can send bursts of correlated messages (e.g., by doing a file transfer that results in the segmentation of a block of data into a number of consecutive signaling messages) through SS7 networks. These message bursts with short interarrival times could have an adverse impact on the delay performance of the SS7 networks. A control mechanism, Credit Manager, is investigated in this paper to regulate incoming traffic to the SS7 network by imposing appropriate time separation between messages when the incoming stream is too bursty. The credit manager has a credit bank where credits accrue at a fixed rate up to a prespecified credit bank capacity. When a message arrives, the number of octets in that message is compared to the number of credits in the bank. If the number of credits is greater than or equal to the number of octets, then the message is accepted for transmission and the number of credits in the bank is decremented by the number of octets. If the number of credits is less than the number of octets, then the message is delayed until enough credits are accumulated. This paper presents simulation results showing delay performance of the SS7 ISUP and TCAP message traffic with a range of correlated message traffic, and control parameters of the credit manager (i.e., credit generation rate and bank capacity) are determined that ensure the traffic entering the SS7 network is acceptable. The results show that control parameters can be set so that for any incoming traffic stream there is no detrimental impact on the SS7 ISUP and TCAP message delay, and the credit manager accepts a wide range of traffic patterns without causing significant delay.
Full Text Available A Road Accident Prevention (RAP scheme based on Vehicular Backbone Network (VBN structure is proposed in this paper for Vehicular Ad-hoc Network (VANET. The RAP scheme attempts to prevent vehicles from highway road traffic accidents and thereby reduces death and injury rates. Once the possibility of an emergency situation (i.e. an accident is predicted in advance, instantly RAP initiates a highway road traffic accident prevention scheme. The RAP scheme constitutes the following activities: (i the Road Side Unit (RSU constructs a Prediction Report (PR based on the status of the vehicles and traffic in the highway roads, (ii the RSU generates an Emergency Warning Message (EWM based on an abnormal PR, (iii the RSU forms a VBN structure and (iv the RSU disseminates the EWM to the vehicles that holds the high Risk Factor (RF and travels in High Risk Zone (HRZ. These vehicles might reside either within the RSU's coverage area or outside RSU's coverage area (reached using VBN structure. The RAP scheme improves the performance of EWM dissemination in terms of increase in notification and decrease in end-to-end delay. The RAP scheme also reduces infrastructure cost (number of RSUs by formulating and deploying the VBN structure. The RAP scheme with VBN structure improves notification by 19 percent and end-to-end delay by 14.38 percent for a vehicle density of 160 vehicles. It is also proved from the simulation experiment that the performance of RAP scheme is promising in 4-lane highway roads.

Computerized, Internet-delivered interventions can be efficacious; however, uptake and maintaining sustained client engagement are still big challenges. We see the development of effective engagement strategies as the next frontier in online health interventions, an area where much creative research has begun. We also argue that for engagement strategies to accomplish their purpose with novel targeted populations, they need to be tailored to such populations (ie, content is designed with the target population in mind). User-centered design frameworks provide a theoretical foundation for increasing user engagement and uptake by including users in development. However, deciding how to implement this approach to engage users in mental health intervention development is challenging. The aim of this study was to get user input and feedback on acceptability of messaging content intended to engage suicidal individuals. In March 2013, clinic intake staff distributed flyers announcing the study, "Your Feedback Counts" to potential participants (individuals waiting to be seen for a mental health appointment) together with the Patient Health Questionnaire. The flyer explained that a score of two or three ("more than half the days" or "nearly every day" respectively) on the suicide ideation question made them eligible to provide feedback on components of a suicide prevention intervention under development. The patient could access an anonymous online survey by following a link. After providing consent online, participants completed the anonymous survey. Thirty-four individuals provided data on past demographic information. Participants reported that they would be most drawn to an intervention where they knew that they were cared about, that was personalized, that others like them had found it helpful, and that included examples with real people. Participants preferred email invitations with subject lines expressing concern and availability of extra resources. Participants also
Full Text Available Abstract Background Although most patients with low back pain (LBP recover within a few weeks a significant proportion has recurrent episodes or will develop chronic low back pain. Several mainly psychosocial risk factors for developing chronic LBP have been identified. However, effects of preventive interventions aiming at behavioural risk factors and unfavourable cognitions have yielded inconsistent results. Risk tailored interventions may provide a cost efficient and effective means to take systematic account of the individual risk factors but evidence is lacking. Methods/Design This study will be a cluster-randomised controlled trial comparing screening and a subsequent risk tailored intervention for patients with low back pain to prevent chronic low back pain compared to treatment as usual in primary care. A total of 600 patients from 20 practices in each study arm will be recruited in Berlin and Goettingen. The intervention comprises the following elements: Patients will be assigned to one of four risk groups based on a screening questionnaire. Subsequently they receive an educational intervention including information and counselling tailored to the risk group. A telephone/email consulting service for back pain related problems are offered independent of risk group assignment. The primary outcomes will be functional capacity and sick leave. Discussion This trial will evaluate the effectiveness of screening for risk factors for chronic low back pain followed by a risk tailored intervention to prevent chronic low back pain. This trial will contribute new evidence regarding the flexible use of individual physical and psychosocial risk factors in general practice. Trial registration ISRCTN 68205910

Wireless sensor networks are highly indispensable for securing network protection. Highly critical attacks of various kinds have been documented in wireless sensor network till now by many researchers. The Sybil attack is a massive destructive attack against the sensor network where numerous genuine identities with forged identities are used for getting an illegal entry into a network. Discerning the Sybil attack, sinkhole, and wormhole attack while multicasting is a tremendous job in wireless sensor network. Basically a Sybil attack means a node which pretends its identity to other nodes. Communication to an illegal node results in data loss and becomes dangerous in the network. The existing method Random Password Comparison has only a scheme which just verifies the node identities by analyzing the neighbors. A survey was done on a Sybil attack with the objective of resolving this problem. The survey has proposed a combined CAM-PVM (compare and match-position verification method) with MAP (message authentication and passing) for detecting, eliminating, and eventually preventing the entry of Sybil nodes in the network. We propose a scheme of assuring security for wireless sensor network, to deal with attacks of these kinds in unicasting and multicasting.

The lack of a theory-based understanding of indoor tanning is a major impediment to the development of effective messages to prevent or reduce this behavior. This study applied the Comprehensive Indoor Tanning Expectations (CITE) scale in an analysis of indoor tanning behavior among sorority women (total N = 775). Confirmatory factor analyses indicated that CITE positive and negative expectations were robust, multidimensional factors and that a hierarchical structure fit the data well. Social cognitive theory-based structural equation models demonstrated that appearance-oriented variables were significantly associated with outcome expectations. Outcome expectations were, in turn, significantly associated with temptations to tan, intention to tan indoors, and indoor tanning behavior. The implications of these findings for the development of messages to prevent and reduce indoor tanning behavior are discussed in two domains: (a) messages that attempt to change broader societal perceptions about tan skin, and (b) messages that focus more narrowly on indoor tanning-challenging positive expectations, enhancing negative expectations, and encouraging substitution of sunless tanning products.

Preventing smoking initiation among adolescents is crucial to reducing tobacco-caused death and disease. This study focuses on the effectiveness of a Web-based computer-tailored smoking prevention intervention aimed at adolescents. The intent of the study was to describe the intervention characteristics and to show the effectiveness and results of a randomized controlled trial. We hypothesized that the intervention would prevent smoking initiation among Dutch secondary school students aged 10-20 years and would have the largest smoking prevention effect among the age cohort of 14-16 years, as smoking uptake in that period is highest. The intervention consisted of a questionnaire and fully automated computer-tailored feedback on intention to start smoking and motivational determinants. A total of 89 secondary schools were recruited via postal mail and randomized into either the computer-tailored intervention condition or the control condition. Participants had to complete a Web-based questionnaire at baseline and at 6-month follow-up. Data on smoking initiation were collected from 897 students from these schools. To identify intervention effects, multilevel logistic regression analyses were conducted using multiple imputation. Smoking initiation among students aged 10-20 years was borderline significantly lower in the experimental condition as compared to the control condition 6 months after baseline (OR 0.25, 95% CI 0.05-1.21, P=.09). Additional analyses of the data for the 14-16 year age group showed a significant effect, with 11.5% (24/209) of the students in the control condition reporting initiation compared to 5.7% (10/176) in the experimental condition (OR 0.22, 95% CI 0.05-1.02, P=.05). No moderation effects were found regarding gender and educational level. The findings of this study suggest that computer-tailored smoking prevention programs are a promising way of preventing smoking initiation among adolescents for at least 6 months, in particular among the

To redress gaps in injection drug users' (IDUs) knowledge about hepatitis risk and prevention, we developed a brief intervention to be delivered to IDUs at syringe exchange programs (SEPs) in three US cities. Following a month-long campaign in which intervention packets containing novel injection hygiene supplies and written materials were distributed to every client at each visit, intervention effectiveness was evaluated by comparing exposed and unexposed participants' self-reported injection practices. Over one-quarter of the exposed group began using the novel hygiene supplies which included an absorbent pad ("Safety Square") to stanch blood flow post-injection. Compared to those unexposed to the intervention, a smaller but still substantial number of exposed participants continued to inappropriately use alcohol pads post-injection despite exposure to written messages to the contrary (22.8% vs. 30.0%). It should also be noted that for those exposed to the intervention, 8% may have misused Safety Squares as part of pre-injection preparation of their injection site; attention should be paid to providing explicit and accurate instruction on the use of any health promotion materials being distributed. While this study indicates that passive introduction of risk reduction materials in injection drug users through syringe exchange programs can be an economical and relatively simple method of changing behaviors, discussions with SEP clients regarding explicit instructions about injection hygiene and appropriate use of novel risk reduction materials is also needed in order to optimize the potential for adoption of health promotion behaviors. The study results suggest that SEP staff should provide their clients with brief, frequent verbal reminders about the appropriate use when distributing risk reduction materials. Issues related to format and language of written materials are discussed.

Disclosure of HIV serostatus by HIV-infected individuals is considered a prevention strategy, under the assumption that disclosure will prompt risk reduction practices among sex partners. We examined patients' self-reports regarding disclosure messages they found relevant as part of prevention with positives (PwP) interventions in clinical settings. We conducted 52 in-depth interviews with patients participating in 13 PwP interventions. We found that the opportunity to reflect about living with HIV, explore fears of stigma and rejection, develop communication skills and strategies to disclose, and explore a sense of responsibility influenced patients' intention to disclose and their disclosure practices. PwP interventions need to include a combination of messages about disclosure strategies, stigma, and communication, as well as helping patients frame disclosure as a process that includes situations and interactions to consider post-disclosure. PwP disclosure counseling can help influence a shift in patients' risk towards safer sex practices.

Bullying is a significant public health issue among middle school-aged youth. Current prevention programs have only a moderate impact. Cell phone text messaging technology (mHealth) can potentially overcome existing challenges, particularly those that are structural (e.g., limited time that teachers can devote to non-educational topics). To date, the description of the development of empirically-based mHealth-delivered bullying prevention programs are lacking in the literature. To describe the development of BullyDown, a text messaging-based bullying prevention program for middle school students, guided by the Social-Emotional Learning model. We implemented five activities over a 12-month period: (1) national focus groups (n=37 youth) to gather acceptability of program components; (2) development of content; (3) a national Content Advisory Team (n=9 youth) to confirm content tone; and (4) an internal team test of software functionality followed by a beta test (n=22 youth) to confirm the enrollment protocol and the feasibility and acceptability of the program. Recruitment experiences suggested that Facebook advertising was less efficient than using a recruitment firm to recruit youth nationally, and recruiting within schools for the pilot test was feasible. Feedback from the Content Advisory Team suggests a preference for 2-4 brief text messages per day. Beta test findings suggest that BullyDown is both feasible and acceptable: 100% of youth completed the follow-up survey, 86% of whom liked the program. Text messaging appears to be a feasible and acceptable delivery method for bullying prevention programming delivered to middle school students.

Worldwide, children under the age of 5 years are at particular risk of drowning. Responding to this need requires the development of evidence-informed drowning prevention strategies. Historically, drowning prevention strategies have included denying access, learning survival skills and providing supervision, as well as education and information which includes the use of mass media. Interventions underpinned by behavioural theory and formative evaluation tend to be more effective, yet few practical examples exist in the drowning and/or injury prevention literature. The Health Belief Model and Social Cognitive Theory will be used to explore participants' perspectives regarding proposed mass media messaging. This paper describes a qualitative protocol to undertake formative research to develop theory-based messages for a child drowning prevention campaign. The primary data source will be focus group interviews with parents and caregivers of children under 5 years of age in metropolitan and regional Western Australia. Qualitative content analysis will be used to analyse the data. This study will contribute to the drowning prevention literature to inform the development of future child drowning prevention mass media campaigns. Findings from the study will be disseminated to practitioners, policymakers and researchers via international conferences, peer and non-peer-reviewed journals and evidence summaries. The study was submitted and approved by the Curtin University Human Research Ethics Committee. Published by the BMJ Publishing Group Limited.

Reducing access to firearms as a suicide prevention strategy is limited in the US today because of divergent cultural attitudes and political contentiousness surrounding gun restrictions. This research examined the effects of culturally-specific suicide prevention messages on the likelihood of restricting firearm access during periods of suicide risk. Focus groups and key informant interviews were conducted with rural gun owners in order to develop a suicide prevention message that highlighted the importance of restricting access to firearms during periods of risk without threatening second amendment concerns. The effectiveness of this gun culture message, relative to standard suicide prevention messaging and a control condition, was then tested with a national sample of gun owners. Relative to all other conditions, respondents who received our culturally-specific message in conjunction with standard suicide prevention content reported the greatest likelihood of taking steps to restrict access to firearms. This tendency was enhanced for individuals who were more politically conservative, lived in more rural areas, and supported gun rights to a stronger degree. Findings underscore the importance of attending to cultural factors in public health messaging. Messaging that respects the values of gun owners could hold promise in promoting firearm restriction for suicide prevention.

The purpose of this study was to evaluate the effect of message framing on women's intention to perform cytomegalovirus (CMV) prevention behaviors involving handwashing, not sharing food and eating utensils, not kissing a child on the lips and not placing a pacifier in the mouth after it was in a child's mouth. An online panel of women 18-40 years, who were pregnant or planning a pregnancy were randomized in a 2 × 2 factorial design to receive 1 of 4 CMV fact sheets. The fact sheets were framed as either what could be gained or be lost by following (or not) the recommendations and the likelihood of being affected by CMV (i.e., small chance or one of the most common infections in infants). The questionnaire measured CMV knowledge, participation in CMV risk or prevention behaviors, perceived severity of and susceptibly to CMV, and the perceived control over and the efficacy of recommended prevention behaviors. The dependent variable, intention to modify behavior, was an index score that ranged from 0 to 16 with higher values indicating greater intention. Linear regression was used to evaluate the association between all independent variables and overall behavioral intention. The sample included 840 women; 15.5% were familiar with CMV. Behavioral intention was high (M = 10.43; SD = 5.13) but did not differ across the message frames (p = 0.23). Overall, behavioral intention was predicted by CMV knowledge, message credibility, perceived severity of CMV, perceived behavioral control and response efficacy. Significant interactions with gain vs. loss frame were observed for perceived behavioral control (p = 0.03) and response efficacy (p = .003). Framing CMV messages by what women stand to gain or lose interacts with perceived behavioral control and response efficacy to influence behavioral intention. Perceived behavioral control and response efficacy were most predictive of behavioral intention overall regardless of frame. Messaging that focuses

Understanding the appropriate medium to communicate health promotion messages is vital for improving personal and societal health. As increasingly more people utilize social media for health information, public health practitioners use these platforms to engage an existing audience in health promotion messages. In this study, the relational framing theory was used as a lens for studying how message framing may influence social media audience engagement. Specifically, we assessed how posts from Tobacco Free Florida's Facebook page were framed as either dominant-submissive or affiliate-disaffiliate to an implied audience of either smokers, nonsmokers, active quitters, or a mixed audience, and the extent to which a direct call for engagement, in terms of a request to comment, like, or share the post, was used for audience engagement. A three-way interaction for the level of engagement through comments was significant, F(3217) = 7.11, p implied audience choice played a role in audience engagement with smoking cessation posts on social media. Implied audiences of Tobacco Free Florida's posts included smokers, those who are trying to quit, and nonsmokers as health promotion can be targeted at the individual's health, social support infrastructure, or the well-being of the society, and implications for strategic message design and audience targeting are discussed.

Our evaluation study identifies facilitators and barriers to participation among families participating in the treatment arm of Stanford ECHALE. This culturally tailored obesity prevention trial consisted of a combined intervention with two main treatment components: 1) a folkloric dance program; and 2) a screen time reduction curriculum designed for 7-11 year old Latinas and their families. We conducted 83 interviews (40 parents and 43 girls) in participant homes after 6 months of enrollment in the ECHALE trial. The Spradley ethnographic method and NVivo 8.0 were used to code and analyze narrative data. Three domains emerged for understanding participation: 1) family cohesiveness; 2) perceived gains; and 3) culturally relevant program structure. Two domains emerged for non-participation: program requirements and perceived discomforts. Non-parametric, Spearman's rank correlation coefficients were calculated to assess the relationships with participant attendance data. Sustained participation was most strongly influenced by the domain perceived gains when parents reported better self-esteem, confidence, improved attitude, improved grades, etc. (Spearman r = .45, P = .003). Alternatively, under the domain, perceived discomforts, with subthemes such as child bullying, participation in the combined intervention was inversely associated with attendance (Spearman r = -.38, P = .02). Family-centered, school-based, community obesity prevention programs that focus on tangible short-term gains for girls may generate greater participation rates, enhance social capital, and promote community empowerment. These factors can be emphasized in future obesity prevention program design and implementation.

Preventing excessive alcohol use among adolescents is important not only to foster individual and public health, but also to reduce alcohol-related costs inside and outside the health care sector. Computer tailoring can be both effective and cost-effective for working with many lifestyle behaviors, yet the available information on the cost-effectiveness of computer tailoring for reducing alcohol use by adolescents is limited as is information on the costs and benefits pertaining to sectors outside the health care sector, also known as intersectoral costs and benefits (ICBs). The aim was to assess the cost-effectiveness of a Web-based computer-tailored intervention for reducing alcohol use and binge drinking by adolescents from a health care perspective (excluding ICBs) and from a societal perspective (including ICBs). Data used were from the Alcoholic Alert study, a cluster randomized controlled trial with randomization at the level of schools into two conditions. Participants either played a game with tailored feedback on alcohol awareness after the baseline assessment (intervention condition) or received care as usual (CAU), meaning that they had the opportunity to play the game subsequent to the final measurement (waiting list control condition). Data were recorded at baseline (T0=January/February 2014) and after 4 months (T1=May/June 2014) and were used to calculate incremental cost-effectiveness ratios (ICERs), both from a health care perspective and a societal perspective. Stochastic uncertainty in the data was dealt with by using nonparametric bootstraps (5000 simulated replications). Additional sensitivity analyses were conducted based on excluding cost outliers. Subgroup cost-effectiveness analyses were conducted based on several background variables, including gender, age, educational level, religion, and ethnicity. From both the health care perspective and the societal perspective for both outcome measures, the intervention was more costly and more
"If I don't use a condom … I would be stressed in my heart that I've done something wrong": Routine Prevention Messages Preclude Safer Conception Counseling for HIV-Infected Men and Women in South Africa.

Intended conception likely contributes to a significant proportion of new HIV infections in South Africa. Safer conception strategies require healthcare provider-client communication about fertility intentions, periconception risks, and options to modify those risks. We conducted in-depth interviews with 35 HIV-infected men and women accessing care in South Africa to explore barriers and promoters to patient-provider communication around fertility desires and intentions. Few participants had discussed personal fertility goals with providers. Discussions about pregnancy focused on maternal and child health, not sexual HIV transmission; no participants had received tailored safer conception advice. Although participants welcomed safer conception counseling, barriers to client-initiated discussions included narrowly focused prevention messages and perceptions that periconception transmission risk is not modifiable. Supporting providers to assess clients' fertility intentions and offer appropriate advice, and public health campaigns that address sexual HIV transmission in the context of conception may improve awareness of and access to safer conception strategies.

Full Text Available Abstract Background Suicide is a leading cause of death among Indigenous youth worldwide. The aim of this literature review was to determine the cultural appropriateness and identify evidence for the effectiveness of current gatekeeper suicide prevention training programs within the international Indigenous community. Method Using a systematic strategy, relevant databases and targeted resources were searched using the following terms: ‘suicide’, ‘gatekeeper’, ‘training’, ‘suicide prevention training’, ‘suicide intervention training’ and ‘Indigenous’. Other internationally relevant descriptors for the keyword “Indigenous” (e.g. “Maori”, “First Nations”, “Native American”, “Inuit”, “Metis” and “Aboriginal” were also used. Results Six articles, comprising five studies, met criteria for inclusion; two Australian, two from USA and one Canadian. While pre and post follow up studies reported positive outcomes, this was not confirmed in the single randomised controlled trial identified. However, the randomised controlled trial may have been underpowered and contained participants who were at higher risk of suicide pre-training. Conclusion Uncontrolled evidence suggests that gatekeeper training may be a promising suicide intervention in Indigenous communities but needs to be culturally tailored to the target population. Further RCT evidence is required.

Background Equipping members of a target population to deliver effective public health messaging to peers is an established approach in health promotion. The Sources of Strength program has demonstrated the promise of this approach for “upstream” youth suicide prevention. Text messaging is a well-established medium for promoting behavior change and is the dominant communication medium for youth. In order for peer ‘opinion leader’ programs like Sources of Strength to use scalable, wide-reaching media such as text messaging to spread peer-to-peer messages, they need techniques for assisting peer opinion leaders in creating effective testimonials to engage peers and match program goals. We developed a Web interface, called Stories of Personal Resilience in Managing Emotions (StoryPRIME), which helps peer opinion leaders write effective, short-form messages that can be delivered to the target population in youth suicide prevention program like Sources of Strength. Objective To determine the efficacy of StoryPRIME, a Web-based interface for remotely eliciting high school peer leaders, and helping them produce high-quality, personal testimonials for use in a text messaging extension of an evidence-based, peer-led suicide prevention program. Methods In a double-blind randomized controlled experiment, 36 high school students wrote testimonials with or without eliciting from the StoryPRIME interface. The interface was created in the context of Sources of Strength–an evidence-based youth suicide prevention program–and 24 ninth graders rated these testimonials on relatability, usefulness/relevance, intrigue, and likability. Results Testimonials written with the StoryPRIME interface were rated as more relatable, useful/relevant, intriguing, and likable than testimonials written without StoryPRIME, P=.054. Conclusions StoryPRIME is a promising way to elicit high-quality, personal testimonials from youth for prevention programs that draw on members of a target

This article describes formative research (a pilot study, interviews, and focus groups) conducted as part of a feasibility test of 2 versions (Analysis vs. Planning) of a brief media literacy intervention titled Youth Message Development (YMD). The intervention targets high school student alcohol use with activities to understand persuasion strategies, increase counter-arguing, and then apply these new skills to ad analysis or a more engaging ad poster planning activity. Based on the theory of active involvement (Greene, 2013), the Planning curriculum is proposed to be more effective than the Analysis curriculum. Overall, results of the formative research indicated that students (N = 182) and mentors/teachers (N = 53) perceived the YMD Planning curriculum as more interesting, involving, and novel, and these ratings were associated with increased critical thinking about the impact of advertising, lower alcohol use intentions, and fewer positive expectations about the effects of alcohol use. Qualitative feedback indicated a need to supplement alcohol-focused ad stimuli with ads targeting other advertising images, use incentives and competition-based activities to further enhance student motivation, and provide flexibility to enhance the appropriateness of the curriculum to various settings. These concerns led to the development of a revised curriculum and plans for further study. PMID:27684111

In response to the growing numbers of young people affected by HIV around the world, MTV (Music TV), the world's largest television network, has aired a global HIV prevention campaign since 1999, expanding it into a multicomponent campaign in 2002. Questions have been raised, however, about whether MTV is an appropriate channel for these messages, given its provocative content and its reach to those at the upper end of the socioeconomic scale. To address questions about who MTV reaches, viewership data were analyzed from baseline surveys conducted as part of an evaluation of the 2002 HIV prevention campaign. The two sites included in this analysis were Kathmandu, Nepal, and São Paulo, Brazil-each with very different cultures and media environments. We found that, in general, heavier viewers of MTV are younger, better educated, and more dependent on their parents, and they have more access to satellite television and the Internet. MTV viewing was associated with positive attitudes toward HIV prevention behaviors (except for abstinence until marriage) but not with premarital sexual activity.

Computer-tailored programs may help to prevent overweight and obesity, which are worldwide public health problems. This study investigated (1) the 12-month effectiveness of a video- and text-based computer-tailored intervention on energy intake, physical activity, and body mass index (BMI), and (2) the role of educational level in intervention effects. A randomized controlled trial in The Netherlands was conducted, in which adults were allocated to a video-based condition, text-based condition, or control condition, with baseline, 6 months, and 12 months follow-up. Outcome variables were self-reported BMI, physical activity, and energy intake. Mixed-effects modelling was used to investigate intervention effects and potential interaction effects. Compared to the control group, the video intervention group was effective regarding energy intake after 6 months (least squares means (LSM) difference = -205.40, p = 0.00) and 12 months (LSM difference = -128.14, p = 0.03). Only video intervention resulted in lower average daily energy intake after one year (d = 0.12). Educational role and BMI did not seem to interact with this effect. No intervention effects on BMI and physical activity were found. The video computer-tailored intervention was effective on energy intake after one year. This effect was not dependent on educational levels or BMI categories, suggesting that video tailoring can be effective for a broad range of risk groups and may be preferred over text tailoring.

The Relationship of Repeated Technical Assistance Support Visits to the Delivery of Positive Health, Dignity, and Prevention (PHDP) Messages by Healthcare Providers in Mozambique: A Longitudinal Multilevel Analysis.
Gutin, Sarah A; Amico, K Rivet; Hunguana, Elsa; Munguambe, António Orlando; Rose, Carol Dawson
Positive health, dignity, and prevention (PHDP) is Mozambique's strategy to engage clinicians in the delivery of prevention messages to their HIV-positive clients. This national implementation strategy uses provider trainings on offering key messages and focuses on intervening on 9 evidence-based risk reduction areas. We investigated the impact of longitudinal technical assistance (TA) as an addition to this basic training. We followed 153 healthcare providers in 5 Mozambican provinces over 6 months to evaluate the impact of on-site, observation-based TA on PHDP implementation. Longitudinal multilevel models were estimated to model change in PHDP message delivery over time among individual providers. With each additional TA visit, providers delivered about 1 additional PHDP message ( P < .001); clinicians and nonclinicians started at about the same baseline level, but clinicians improved more quickly ( P = .004). Message delivery varied by practice sector; maternal and child health sectors outperformed other sectors. Longitudinal TA helped reach the programmatic goals of the PHDP program in Mozambique.

The need for formative research in designing mass media health-education messages is widely accepted; however, distinct methodologies for developing such messages are less well documented. This article describes a culture-centered approach for developing messages to promote sexual risk reduction in urban African American adolescents. The method uses qualitative formative research to identify "competing narratives" that support healthy behavior despite the dominance of messages that favor risk-taking behavior. The method is illustrated using qualitative analysis of semistructured interviews with 124 adolescents. Analysis focuses on two barriers to sexual risk reduction: (a) social pressure for early initiation of sexual intercourse and (b) perceptions that condoms reduce sexual pleasure. We demonstrate how competing narratives identified in the analysis can be featured in radio and television messages advocating healthy behavior by modeling risk-reducing negotiation skills.

We assessed the efficacy of a multicomponent culturally tailored HIV/STI prevention intervention programme on consistent condom use and STI incidence among foreign Thai and Vietnamese female entertainment workers (FEWs) in Singapore. We conducted a quasi-experimental pretest and post-test intervention trial with a comparison group. We recruited 220 participants (115 Vietnamese and 105 Thai) for the comparison group, followed by the intervention group (same number) from the same sites which were purposively selected after a 3-month interval period. Both groups completed a self-administered anonymous questionnaire and STI testing for cervical gonorrhoea and Chlamydia, as well as pharyngeal gonorrhoea at baseline and 6-week follow-up. The peer-led intervention consisted of behavioural (HIV/STI education and condom negotiation skills), biomedical (STI screening and treatment services) and structural components (access to free condoms). We used the mixed effects Poisson regression model accounting for clustering by establishment venue to compute the adjusted risk ratio (aRR) of the outcomes at follow-up. At follow-up, the intervention group was more likely than the comparison group to report consistent condom use for vaginal sex with paid (aRR 1.77; 95% CI 1.71 to 1.83) and casual (aRR 1.81; 95% CI 1.71 to 1.91) partners. For consistent condom use for oral sex, this was aRR 1.50; 95% CI 1.23 to 1.82 with paid and aRR 1.54; 95% CI 1.22 to 1.95 with casual partners. STI incidence at follow-up was significantly lower in the intervention (6.8 per 100 FEWs) than the comparison (14.8 per 100 FEWs) group (aRR 0.42; 95% CI 0.32 to 0.55). This trial was effective in promoting consistent condom use for vaginal and oral sex as well as reducing STI incidence among the foreign Thai and Vietnamese FEWs in Singapore. The feasibility of scaling up the interventions to all entertainment establishments in Singapore should be assessed. © Article author(s) (or their employer

We evaluated Florida-based physicians' awareness and use of the Centers for Disease Control and Prevention's (CDC) "You are the Key" campaign website, including messages to support physicians' human papillomavirus (HPV) vaccine recommendations. Using closed-ended and free-text survey items, physicians' (n=355) practices related to HPV vaccination recommendations for males and use of the CDC's materials were assessed. Descriptive statistics were calculated for closed-ended questions, and thematic analysis was conducted on free-text responses. Over half of physicians were aware of the CDC's website (n=186; 57.9%); of those aware, fewer than half reported using the website (n=86; 46.2%). Slightly more than half reported awareness of the CDC's messages (n=178; 55.3%); however, less than one-third of those aware reported using them (n=56; 31.5%). Physicians' comments on the CDC's messages were favorable; 78.6-93.2% said they would use a message in clinic. Additional research is needed to identify the best mechanisms for resource dissemination and to understand why physicians do not use these messages, despite favorable attitudes. Copyright © 2016.

Type 2 diabetes can often be prevented by lifestyle modification; however, successful lifestyle intervention programmes are labour intensive. Mobile phone messaging is an inexpensive alternative way to deliver educational and motivational advice about lifestyle modification. We aimed to assess whether mobile phone messaging that encouraged lifestyle change could reduce incident type 2 diabetes in Indian Asian men with impaired glucose tolerance. We did a prospective, parallel-group, randomised controlled trial between Aug 10, 2009, and Nov 30, 2012, at ten sites in southeast India. Working Indian men (aged 35-55 years) with impaired glucose tolerance were randomly assigned (1:1) with a computer-generated randomisation sequence to a mobile phone messaging intervention or standard care (control group). Participants in the intervention group received frequent mobile phone messages compared with controls who received standard lifestyle modification advice at baseline only. Field staff and participants were, by necessity, not masked to study group assignment, but allocation was concealed from laboratory personnel as well as principal and co-investigators. The primary outcome was incidence of type 2 diabetes, analysed by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00819455. We assessed 8741 participants for eligibility. 537 patients were randomly assigned to either the mobile phone messaging intervention (n=271) or standard care (n=266). The cumulative incidence of type 2 diabetes was lower in those who received mobile phone messages than in controls: 50 (18%) participants in the intervention group developed type 2 diabetes compared with 73 (27%) in the control group (hazard ratio 0·64, 95% CI 0·45-0·92; p=0·015). The number needed to treat to prevent one case of type 2 diabetes was 11 (95% CI 6-55). One patient in the control group died suddenly at the end of the first year. We recorded no other serious adverse events. Mobile

Full Text Available Abstract Background The impending public health impact of Alzheimer’s disease is tremendous. Physical activity is a promising intervention for preventing and managing Alzheimer’s disease. However, there is a lack of evidence-based public health messaging to support this position. This paper describes the application of the Appraisal of Guidelines Research and Evaluation II (AGREE-II principles to formulate an evidence-based message to promote physical activity for the purposes of preventing and managing Alzheimer’s disease. Methods A messaging statement was developed using the AGREE-II instrument as guidance. Methods included (a conducting a systematic review of reviews summarizing research on physical activity to prevent and manage Alzheimer’s disease, and (b engaging stakeholders to deliberate the evidence and formulate the messaging statement. Results The evidence base consisted of seven systematic reviews focused on Alzheimer’s disease prevention and 20 reviews focused on symptom management. Virtually all of the reviews of symptom management conflated patients with Alzheimer’s disease and patients with other dementias, and this limitation was reflected in the second part of the messaging statement. After deliberating the evidence base, an expert panel achieved consensus on the following statement: “Regular participation in physical activity is associated with a reduced risk of developing Alzheimer’s disease. Among older adults with Alzheimer’s disease and other dementias, regular physical activity can improve performance of activities of daily living and mobility, and may improve general cognition and balance.” The statement was rated favourably by a sample of older adults and physicians who treat Alzheimer’s disease patients in terms of its appropriateness, utility, and clarity. Conclusion Public health and other organizations that promote physical activity, health and well-being to older adults are encouraged to use

Research indicates that maintaining contact either via letter or postcard with at-risk adults following discharge from care services after a suicide attempt (SA) can reduce reattempt risk. Pilot studies have demonstrated that interventions using mobile health (mHealth) technologies are feasible in a suicide prevention setting. The aim of this study was to report three cases of patients recruited in the Suicide Intervention Assisted by Messages (SIAM) study to describe how a mobile intervention may influence follow-up. SIAM is a 2-year, multicenter randomized controlled trial conducted by the Brest University Hospital, France. Participants in the intervention group receive SIAM text messages 48 hours after discharge, then at day 8 and day 15, and months 1, 2, 3, 4, 5, and 6. The study includes participants aged 18 years or older, who have attended a participating hospital for an SA, and have been discharged from the emergency department (ED) or a psychiatric unit (PU) for a stay of less than 7 days. Eligible participants are randomized between the SIAM intervention messages and a control group. In this study, we present three cases from the ongoing SIAM study that demonstrate the capability of a mobile-based brief contact intervention for triggering patient-initiated contact with a crisis support team at various time points throughout the mobile-based follow-up period. Out of the 244 patients recruited in the SIAM randomized controlled trial, three cases were selected to illustrate the impact of mHealth on suicide risk management. Participants initiated contact with the emergency crisis support service after receiving text messages up to 6 months following discharge from the hospital. Contact was initiated immediately following receipt of a text message or up to 6 days following a message. This text message-based brief contact intervention has demonstrated the potential to reconnect suicidal individuals with crisis support services while they are experiencing
Full Text Available BACKGROUND: The aims of the study were to evaluate the effect of providing tailored falls prevention education in hospital on: i engagement in targeted falls prevention behaviors in the month after discharge: ii patients' self-perceived risk and knowledge about falls and falls prevention strategies after receiving the education. METHODS: A pilot randomized controlled trial (n = 50: baseline and outcome assessments conducted by blinded researchers. PARTICIPANTS: hospital inpatients 60 years or older, discharged to the community. Participants were randomized into two groups. The intervention was a tailored education package consisting of multimedia falls prevention information with trained health professional follow-up, delivered in addition to usual care. Outcome measures were engagement in falls prevention behaviors in the month after discharge measured at one month after discharge with a structured survey, and participants' knowledge, confidence and motivation levels before and after receiving the education. The feasibility of providing the intervention was examined and falls outcomes (falls, fall-related injuries were also collected. RESULTS: Forty-eight patients (98% provided follow-up data. The complete package was provided to 21 (84% intervention group participants. Participants in the intervention group were significantly more likely to plan how to safely restart functional activities [Adjusted odds ratio 3.80, 95% CI (1.07, 13.52, p = 0.04] and more likely to complete other targeted behaviors such as completing their own home exercise program [Adjusted odds ratio 2.76, 95% CI (0.72, 10.50, p = 0.14] than the control group. The intervention group was significantly more knowledgeable, confident and motivated to engage in falls prevention strategies after receiving the education than the control group. There were 23 falls (n = 5 intervention; n = 18 control and falls rates were 5.4/1000 patient days (intervention; 18.7/1000 patient days

Web-based computer-tailored interventions often suffer from small effect sizes and high drop-out rates, particularly among people with a low level of education. Using videos as a delivery format can possibly improve the effects and attractiveness of these interventions The main aim of this study was to examine the effects of a video and text version of a Web-based computer-tailored obesity prevention intervention on dietary intake, physical activity, and body mass index (BMI) among Dutch adults. A second study aim was to examine differences in appreciation between the video and text version. The final study aim was to examine possible differences in intervention effects and appreciation per educational level. A three-armed randomized controlled trial was conducted with a baseline and 6 months follow-up measurement. The intervention consisted of six sessions, lasting about 15 minutes each. In the video version, the core tailored information was provided by means of videos. In the text version, the same tailored information was provided in text format. Outcome variables were self-reported and included BMI, physical activity, energy intake, and appreciation of the intervention. Multiple imputation was used to replace missing values. The effect analyses were carried out with multiple linear regression analyses and adjusted for confounders. The process evaluation data were analyzed with independent samples t tests. The baseline questionnaire was completed by 1419 participants and the 6 months follow-up measurement by 1015 participants (71.53%). No significant interaction effects of educational level were found on any of the outcome variables. Compared to the control condition, the video version resulted in lower BMI (B=-0.25, P=.049) and lower average daily energy intake from energy-dense food products (B=-175.58, Pintervention (P=.018). The video version of the Web-based computer-tailored obesity prevention intervention was the most effective intervention and most

Full Text Available The purpose of this study was to investigate how clergy are dealing with HIV prevention and sexuality education of young people in their congregations. An electronic questionnaire was filled in by 142 clergy from white Afrikaans-speaking churches in the Reformed tradition. Results showed that 77% clergy believed that unmarried young people in their congregations are sexually active. More than 85% clergy agreed that it is the task of the church to provide sexuality and HIV prevention education to young congregants. However, not many clergy (13% offered HIV prevention programmes for young people in their own congregations. The main HIV prevention message 85% of clergy were prepared to share with young congregants was �abstinence only� or �your body is the temple of God�. Only 15% clergy (significantly more female clergy were prepared to offer comprehensive sexuality education (abstinence PLUS programmes. The HIV prevention message of the church should at least be in line with the lived experiences and reality of its youth in today�s society. The church can no longer afford to alienate young people through moralism only. She needs an approach that satisfies both morality and reality.Intradisciplinary and/or interdisciplinary implications: This article has implications for the fields of psychology, HIV and AIDS research and pastoral care. It challenges the way the church prepares young people to cope with HIV in a modern society and suggests change in terms of a greater participation in the sexuality education of young people.
Full Text Available Starr Hilliard, Sarah A Gutin, Carol Dawson Rose Department of Community Health Systems, School of Nursing, University of California at San Francisco, San Francisco, CA, USA Background: Family planning is an important HIV prevention tool for women living with HIV (WLHIV. In Mozambique, the prevalence of HIV among women of reproductive age is 13.1% and the average fertility rate is high. However, family planning and reproductive health for WLHIV are under-addressed in Mozambique. This study explores provider descriptions of reproductive health messages in order to identify possible barriers and facilitators to successfully addressing family planning and pregnancy concerns of WLHIV. Methods: In 2006, a Positive Health, Dignity, and Prevention program was introduced in Mozambique focused on training health care providers to work with patients to reduce their transmission risks. Providers received training on multiple components, including family planning and prevention of mother-to-child transmission (PMTCT. In-depth interviews were conducted with 31 providers who participated in the training in five rural clinics in three provinces. Data were analyzed using qualitative content analysis. Results: Analysis showed that providers' clinical messages on family planning, pregnancy, and PMTCT for WLHIV could be arranged along a continuum. Provider statements ranged from saying that WLHIV should not become pregnant and condoms are the only valid form of family planning for WLHIV, to suggesting that WLHIV can have safe pregnancies. Conclusion: These data indicate that many providers continue to believe that WLHIV should not have children and this represents a challenge for integrating family planning into the care of WLHIV. Also, not offering WLHIV a full selection of family planning methods severely limits their ability to protect themselves from unintended pregnancies and to fully exercise their reproductive rights.

Full Text Available Abstract Background To motivate individuals to adhere to a regular physical activity regime, guidelines must be supplemented with persuasive messages that are disseminated widely. While substantial research has examined effective strategies for disseminating physical activity messages, there has been no systematic effort to examine optimal message content. This paper reviews studies that evaluate the effectiveness of three approaches for constructing physical activity messages including tailoring messages to suit individual characteristics of message recipients (message tailoring, framing messages in terms of gains versus losses (message framing, and targeting messages to affect change in self-efficacy (i.e., a theoretical determinant of behavior change. Methods We searched the MEDLINE, PsycINFO, EMBASE and CINAHL databases up to July 2008. Relevant reference lists also were searched. We included intervention trials, field experiments, and laboratory-based studies that aimed to test the efficacy or effectiveness of tailored messages, framed messages and self-efficacy change messages among healthy adults. We used a descriptive approach to analyze emerging patterns in research findings. Based on this evidence we made recommendations for practice and future research. Results Twenty-two studies were identified. Twelve studies evaluated message tailoring. In 10 of these studies, tailored messages resulted in greater physical activity than a control message. Six studies evaluated framed messages. Five of these studies demonstrated that gain-framed messages lead to stronger intentions to be active compared to a control message. Moreover, a gain-frame advantage was evident in three of the four studies that assessed physical activity. Four studies evaluated self-efficacy change messages. The two studies that used an experimental design provide a clear indication that individuals' beliefs can be affected by messages that incorporate types of information

To develop and pilot a theory-based, mobile phone texting component attractive to minority youth as a supplement to the Teen Outreach Program(®), a youth development program for reducing teen pregnancy and school dropout. We conducted iterative formative research with minority youth in multiple focus groups to explore interest in texting and reaction to text messages. We piloted a month-long version of TOP(®) Plus Text with 96 teens at four sites and conducted a computer-based survey immediately after enrollment and at the end of the pilot that collected information about teens' values, social support, self-efficacy, and behaviors relating to school performance, trouble with the law, and sexual activity. After each of the first three weekly sessions we collected satisfaction measures. Upon completion of the pilot we conducted exit interviews with twelve purposively selected pilot participants. We successfully recruited and enrolled minority youth into the pilot. Teens were enthusiastic about text messages complementing TOP(®). Results also revealed barriers: access to text-capable mobile phones, retention as measured by completion of the post-pilot survey, and a need to be attentive to teen literacy. Piloting helped identify improvements for implementation including offering text messages through multiple platforms so youth without access to a mobile phone could receive messages; rewording texts to allow youth to express opinions without feeling judged; and collecting multiple types of contact information to improve follow-up. Thoughtful attention to social and behavioral theory and investment in iterative formative research with extensive consultation with teens can lead to an engaging texting curriculum that enhances and complements TOP(®).

Background Healthful dietary patterns, including eating fruits and vegetables (F&V) and avoiding obesity may decrease the risk of cancer and other chronic diseases. In addition to promoting health for the general population, a cancer diagnosis may provide a “teachable moment,” facilitating the adoption of more healthful eating habits and leading to lower risk of chronic disease and better overall health. Purpose This study was designed to test the effectiveness of two health communication interventions in increasing F&V consumption and physical activity in a sample of older adults (average age 66 years), including both colorectal cancer (CRC) survivors and non-CRC-affected (N-CRC) individuals. Methods Colorectal cancer survivors and N-CRC individuals were recruited from a population-based case-control study and randomly assigned to four conditions using a 2 × 2 design. We tested two different methods of communicating and promoting health behavior change alone or in combination: tailored print communication (TPC) and brief telephone-based motivational interviewing (TMI). Results A significant increase in F&V consumption was found for the combined intervention group in the entire sample (pmotivational interviewing may be an effective and cost-effective method for promoting dietary behavior change among older healthy adults. More research is needed to identify the optimal dose and timing for intervention strategies to promote dietary and physical activity change among both CRC survivors and the general population.

The present study examines the persuasive effects of tailored health messages comparing those tailored to match (versus not match) both chronic cultural frame and momentarily salient cultural frame. Evidence from two studies (Study 1: n = 72 European Americans; Study 2: n = 48 Asian Americans) supports the hypothesis that message persuasiveness increases when chronic cultural frame, health message tailoring and momentarily salient cultural frame all match. The hypothesis was tested using a message about health risks of caffeine consumption among individuals prescreened to be regular caffeine consumers. After being primed for individualism, European Americans who read a health message that focused on the personal self were more likely to accept the message-they found it more persuasive, believed they were more at risk and engaged in more message-congruent behaviour. These effects were also found among Asian Americans who were primed for collectivism and who read a health message that focused on relational obligations. The findings point to the importance of investigating the role of situational cues in persuasive effects of health messages and suggest that matching content to primed frame consistent with the chronic frame may be a way to know what to match messages to.

To test a 2-year community- and family-based obesity prevention program for low-income African American girls: Stanford GEMS (Girls' health Enrichment Multi-site Studies). Randomized controlled trial with follow-up measures scheduled at 6, 12, 18, and 24 months. Low-income areas of Oakland, California. African American girls aged 8 to 10 years (N=261) and their parents or guardians. Families were randomized to one of two 2-year, culturally tailored interventions: (1) after-school hip-hop, African, and step dance classes and a home/family-based intervention to reduce screen media use or (2) information-based health education. Changes in body mass index (BMI). Changes in BMI did not differ between groups (adjusted mean difference [95% confidence interval] = 0.04 [-0.18 to 0.27] per year). Among secondary outcomes, fasting total cholesterol level (adjusted mean difference, -3.49 [95% confidence interval, -5.28 to -1.70] mg/dL per year), low-density lipoprotein cholesterol level (-3.02 [-4.74 to -1.31] mg/dL per year), incidence of hyperinsulinemia (relative risk, 0.35 [0.13 to 0.93]), and depressive symptoms (-0.21 [-0.42 to -0.001] per year) decreased more among girls in the dance and screen time reduction intervention. In exploratory moderator analysis, the dance and screen time reduction intervention slowed BMI gain more than health education among girls who watched more television at baseline (P = .02) and/or those whose parents or guardians were unmarried (P = .01). A culturally tailored after-school dance and screen time reduction intervention for low-income, preadolescent African American girls did not significantly reduce BMI gain compared with health education but did produce potentially clinically important reductions in lipid levels, hyperinsulinemia, and depressive symptoms. There was also evidence for greater effectiveness in high-risk subgroups of girls.

Public health HIV prevention efforts have begun to focus on addressing social and structural factors contributing to HIV risk, such as unstable housing, unemployment and access to healthcare. With a limited body of evidence-based structural interventions for HIV, communities tasked with developing structural changes need a defined process to clarify their purpose and goals. This paper describes the adaptations made to a coalition development model with the purpose of improving the start-up phase for a second group of coalitions. Modifications focused on preparing coalitions to more efficiently apply structural change concepts to their strategic planning activities, create more objectives that met study goals, and enhance coalition procedures, such as building distributed coalition leadership, to better support the mobilization process. We report on primary modifications to the process, findings for the coalitions and recommendations for public health practitioners that are seeking to start a similar coalition. PMID:26785397

There is a dearth of HIV prevention/healthy sexuality programs developed for adolescent gay and bisexual males (AGBM) as young as 14 years old, in part because of the myriad ethical concerns. To address this gap, we present our ethics-related experiences implementing Guy2Guy, a text messaging-based HIV prevention/healthy sexuality program, in a randomized controlled trial of 302 14- to 18-year-old sexual minority males. Potential risks and efforts to reduce these risks are discussed within the framework of the Belmont Report: Respect for persons, beneficence (e.g., risks and benefits), and justice (e.g., fair distribution of benefits and burdens). To ensure "respect for persons," online enrollment was coupled with telephone assent, which included assessing decisional capacity to assent. Beneficence was promoted by obtaining a waiver of parental permission and using a self-safety assessment to help youth evaluate their risk in taking part. Justice was supported through efforts to develop and test the program among those who would be most likely to use it if it were publicly available (e.g., youth who own a cell phone and are enrolled in an unlimited text messaging plan), along with the use of recruitment targets to ensure a racially, ethnically, and regionally diverse sample. It is possible to safely implement a sensitive and HIV prevention/healthy sexuality program with sexual minority youth as young as 14 years old when a rigorous ethical protocol is in place.

In polyphase tailored ceramic forms two distinct modes of radionuclide immobilization occur. At high waste loadings the radionuclides are distributed through most of the ceramic phases in dilute solid solution, as indicated schematically in this paper. However, in the case of low waste loadings, or a high loading of a waste with low radionuclide content, the ceramic can be designed with only selected phases containing the radionuclides. The remaining material forms nonradioactive phases which provide a degree of physical microstructural isolation. The research and development work with polyphase ceramic nuclear waste forms over the past ten years is discussed. It has demonstrated the critical attributes which suggest them as a waste form for future HLW disposal. From a safety standpoint, the crystalline phases in the ceramic waste forms offer the potential for demonstrable chemical durability in immobilizing the long-lived radionuclides in a geologic environment. With continued experimental research on pure phases, analysis of mineral analogue behavior in geochemical environments, and the study of radiation effects, realistic predictive models for waste form behavior over geologic time scales are feasible. The ceramic forms extend the degree of freedom for the economic optimization of the waste disposal system

Two studies were conducted to investigate the role of connectedness with music videos in affecting youths' beliefs about substances (alcohol and tobacco) embedded therein and the potential for a prevention message to limit the impact of these images. The first study used cross-sectional data from a national sample of 1,023 adolescents (54.3% male) to evaluate the relationship between youths' consumption of music videos and their beliefs about the consequences of consuming alcohol and tobacco. A controlled experiment with 151 participants (57% male) then tested whether exposure to smoking in a video affects youths' smoking beliefs and the preventive potential of a pre-video warning. Connectedness to music videos, not overall amount of viewing, is the main correlate of beliefs about the positive outcomes of consuming alcohol/tobacco. A single exposure to a music video with smoking images can increase beliefs that smoking leads to positive consequences, and connected viewers are especially receptive to these images. Alerting youths to the presence of substance messages in a video leads to differential results as a function of connectedness. Many youths spend hours every day watching music videos in which positive visuals about drinking and smoking abound. Rather than the quantity of viewing, it is the degree to which youths immerse themselves in these music videos that enhances their beliefs that smoking and drinking have positive consequences. Interventions that warn youths about the presence of substances in music videos can minimize their influence, but youths highly connected with the music video content are especially resistant to warnings.
In Digestive Disease Week 2016, interesting data were presented on the eventual role of certain foods in inflammatory bowel disease, although the value of these data is relative. Also of interest were epidemiological studies, of which several analysed the natural history of the disease. Some presentations dealt with the search for individual predictive factors, a pressing need in clinical practice. Unfortunately, some of the findings presented were of dubious value. A study suggesting that a simple parameter as increased blood monocytes could be a clear predictive factor of poor outcome could perhaps be highlighted (the results were striking but had multiple limitations). In contrast, more interesting data were presented on monitoring and optimising biological therapy in the search for an individually-tailored approach. New studies were presented on the levels of distinct anti-TNF agents, vedolizumab and even ustekinumab. One study aimed to estimate the safety of anti-TNF agents on the basis of the patient's genetic (and clinical) features. There is no new evidence that will change our clinical practice. Equally, the data on colon cancer prevention will not modify our clinical practice, although one study reported a promising new strategy, consisting of the use of a new stool DNA test, with very promising results in the detection of high-grade dysplasia or colorectal cancer in these patients.

Colorectal cancer (CRC) is the third most commonly diagnosed cancer in males and the second in females throughout the developed world. Population screening using fecal occult blood tests (FOBTs) facilitates early detection and greater chance of survival, but participation rates are low. We developed a Web-based decision tool to provide information tailored to an individual's decision stage for CRC screening and attitude toward screening utilizing the Preventive Health Model (PHM) and Precaution Adoption Process Model (PAPM) as theoretical frameworks for screening behavior. We describe the practical steps employed in the tool's design and the subsequent conduct of an exploratory study. To design a decision tool for CRC screening and conduct an exploratory study among average-risk men and women to (1) test the impact of message type (tailored vs non-tailored) and message delivery modality (Web-based vs paper-based) on attitudes toward screening and screening uptake, and (2) investigate the acceptability of the decision tool and relevance of materials. Participants (n = 100), recruited from a population sample of men and women aged 50-76 residing in urban Adelaide, Australia, were randomly assigned to a control group or one of 4 interventions: (1) Web-based and tailored information, (2) paper-based and tailored information, (3) Web-based and non-tailored (generic) information, or (4) paper-based and non-tailored information. Participation was augmented by snowball recruitment (n = 19). Questionnaires based on PHM variables were administered pre- and post-intervention. Participants were given the opportunity to request an FOBT. Following the intervention, participants discussed the acceptability of the tool. Full data were available for 87.4% (104/119) of participants. Post-intervention, perceived susceptibility scores for individuals receiving tailored information increased from mean 10.6 (SD 2.1) to mean 11.8 (SD 2.2). Scores on self-efficacy increased in the

Depression and anxiety are common and co-morbid disorders that affect a significant proportion of students. Innovative prevention strategies targeting both conditions are needed to reduce their health burden and costs. ICare Prevent is such an innovative strategy and contains a transdiagnostic individually tailored Internet-based and mobile-supported intervention. It addresses common risk factors of depression and anxiety as part of a large EU-funded multi-country project* (ICare). Little is known about the clinical and cost-effectiveness of this type of intervention compared to care as usual (CAU) for college students. We hypothesize that ICare Prevent will be more (cost-)effective than CAU in the reduction of symptoms of depression and anxiety. A three-arm, parallel, randomized controlled superiority trial will be conducted comparing a guided and an unguided version of ICare Prevent with a control group receiving CAU. The trial will be open-label but outcome assessors will be blinded. A total of 252 college students (age ≥ 16 years) with subclinical symptoms of depression defined as a score ≥ 16 on the Center for Epidemiological Studies Depression Scale (CES-D), and/or anxiety, defined as a score ≥ 5 on the Generalized Anxiety Disorder scale (GAD-7), will be included. Those meeting diagnostic criteria for a depressive or anxiety disorder will be excluded. The primary outcome is change in disorder specific symptom severity from baseline to post-intervention. Secondary endpoints include self-reported depression and anxiety symptoms as well as time to onset of a mood or anxiety disorder until 12-month follow-up. Societal costs and quality of life will be assessed to estimate the intervention's cost-effectiveness compared to CAU. Transdiagnostic individually tailored Internet-based prevention could be a (cost-)effective approach to tackle the disease burden of depression and anxiety among college students.

To provide a comprehensive overview of trends in news coverage about sun protection issues in an Australian setting over a 14-year period. A content analysis was performed on all relevant articles (N=547) published in two major daily newspapers, The Age and the Herald Sun, from 1993 to 2006. Articles were coded for article type, prominence, theme, spokesperson, topic slant and opinion slant. The most frequent themes were the health effects of ultraviolet (UV) radiation exposure (24% of articles), education/prevention (14%) and product issues (12%). Themes that became more dominant over time were vitamin D issues, solaria issues and fake tans. Sixty per cent of articles included a pro-sun protection spokesperson and 12% an anti-sun protection spokesperson, with the profile of anti-sun protection spokespeople increasing over time. Half the articles reported on topics positive for sun protection, whereas 18% reported on negative topics; however, this difference narrowed considerably from 2001 onwards. In opinionated articles, the opinions expressed by authors were mainly positive (57%) rather than negative (7%) for sun protection. The findings suggest that the mix of sun protection issues covered and views of sun protection have changed over time, resulting in greater coverage of controversies and issues not necessarily positive for sun protection objectives. These findings imply that evaluation of paid skin cancer prevention public education campaigns may need to take account of the changing news media environment in which they take place.

Few studies have evaluated text message content preferences to support evidence-based treatment approaches for opioid use disorders, and none in primary care office-based buprenorphine treatment settings. This study assessed the acceptability and preferences for a tailored text message intervention in support of core office-based buprenorphine treatment medical management components (e.g., treatment adherence, encouraging abstinence, 12-step group participation, motivational interviewing, and patient-provider communication as needed). There were 97 patients enrolled in a safety net office-based buprenorphine treatment program who completed a 24-item survey instrument that consisted of multiple-choice responses, 7-point Likert-type scales, binomial "Yes/No" questions, and open-ended responses. The sample was predominately male (81%), had an average age of 46 years, and was diverse (64% ethnic/racial minorities); 56% lacked stable employment. Respondents were interested in receiving text message appointment reminders (90%), information pertaining to their buprenorphine treatment (76%), supportive content (70%), and messages to reduce the risk of relapse (88%). Participants preferred to receive relapse prevention text messages during all phases of treatment: immediately after induction into buprenorphine treatment (81%), a "few months" into treatment (57%), and after discontinuing buprenorphine treatment (72%). Respondents also expressed interest in text message content enhancing self-efficacy, social support, and frequent provider communication to facilitate unobserved "home" induction with buprenorphine. Older participants were significantly less receptive to receiving text message appointment reminders; however, they were as interested in receiving supportive, informational, and relapse prevention components compared to younger respondents. Implications for integrating a text message support system in office-based buprenorphine treatment are discussed.

Objective To test a 2-year community- and family-based obesity prevention intervention for low-income African-American girls. Design Randomized controlled trial with follow-up measures scheduled at 6, 12, 18 and 24 months. Setting Low-income areas of Oakland, CA. Participants 261 8–10 year old African-American girls and their parents/caregivers. Interventions Families were randomized to two-year, culturally-tailored interventions: (1) after school Hip-Hop, African and Step dance classes and a home/family-based intervention to reduce screen media use or (2) information-based health education. Main Outcome Measure Body mass index (BMI) change. Results Changes in BMI did not differ between groups (adjusted mean difference [95% confidence interval] = 0.04 [−.18, .27] kg/m2 per year). Among secondary outcomes, fasting total cholesterol (−3.49 [−5.28, −1.70] mg/dL per year), LDL-cholesterol (−3.02 [−4.74, −1.31] mg/dL per year), incidence of hyperinsulinemia (Relative Risk 0.35 [0.13, 0.93]), and depressive symptoms (−0.21 [−0.42, −0.001] per year) fell more among girls in the dance and screen time reduction intervention. In exploratory moderator analysis, the dance and screen time reduction intervention slowed BMI gain more than health education among girls who watched more television at baseline (P=.02) and/or those whose parents/guardians were unmarried (Pdance and screen time reduction intervention for low-income, preadolescent African-American girls did not significantly reduce BMI gain compared to health education, but produced potentially clinically important reductions in lipids, hyperinsulinemia, and depressive symptoms. There was also evidence for greater effectiveness in high-risk subgroups of girls. PMID:21041592

People with dementia have a disproportionately high rate of falls and fractures and poorer outcomes, yet there is currently no evidence to guide falls prevention in this population. A randomised trial design was used to test feasibility of study components and acceptability of a home hazard reduction and balance and strength exercise fall prevention program. The program was tailored to participant's individual cognitive levels and implemented as a carer-supported intervention. Feasibility of recruitment, retention and implementation of intervention were recorded through observation and documented in field notes. Adherence, carer burden and use of task simplification strategies were also monitored. Outcome measures, collected at 12 weeks included physiological, fear of falling, cognitive and functional measures. Recruitment was achievable but may be more challenging in a multisite trial. Twenty two dyads of persons with mild dementia and their carers were randomised to intervention or usual care control group. Of 38 dyads referred to the study, there was a high rate of willingness to participate, with 6 (16%) declining and 10 (26%) not meeting inclusion criteria. The intervention was well received by participants and carers and adherence to both program components was very good. All participants implemented some home safety recommendations (range 19-80%) with half implementing 50% or more. At the end of 12 weeks, 72% of the intervention group were exercising. Both the rate of falling and the risk of a fall were lower in the intervention group but these findings were not significant (RR= 0.50 (95% CI 0.11-2.19). There were no differences in physiological outcome measures between the control and intervention groups. However results were influenced by the small study size and incomplete data primarily in the intervention group at follow up. The pilot study was feasible and acceptable to people with mild dementia and their carers. The lessons learnt included

The Prostate Cancer Prevention Trial was the first clinical trial to show that a direct intervention (5 mg of finasteride daily for 7 years) could reduce a man's risk of developing prostate cancer. Initial results also suggested that men taking finasteride had an increased risk of developing what appeared to be higher-grade disease (Gleason score 7-10). The National Cancer Institute has a congressional mandate to communicate health information to the public and has established methods to reach the public directly and to reach information intermediaries in the media, professional societies, and advocacy groups. The groundbreaking yet complicated results of the Prostate Cancer Prevention Trial were widely disseminated by National Cancer Institute using the social marketing and public-relations strategies and tactics detailed here.

Strategic framing of public messages about HIV pre-exposure prophylaxis (PrEP) may influence public support for policies and programs affecting access. This survey study examined how public attitudes toward PrEP differed based on the social group PrEP was described as benefiting ("beneficiary") and the moderating effect of prejudice. Members of the general public (n = 154) recruited online were randomly assigned to three beneficiary conditions: general population, gay men, or Black gay men. All participants received identical PrEP background information before completing measures of PrEP attitudes (specifying beneficiary), racism, and heterosexism. Despite anticipating greater PrEP adherence among gay men and Black gay men and perceiving PrEP as especially beneficial to the latter, participants expressed lower support for policies/programs making PrEP affordable for these groups vs. the general population. This disparity in support was stronger among participants reporting greater prejudice. Inclusive framing of PrEP in public discourse may prevent prejudice from undermining implementation efforts.

Visual framing can improve health-message effectiveness. Narrative structure provides a template needed for determining how to frame visuals to maximise message effectiveness. Participants (N = 190) were assigned to a message condition determined by segments (establisher, initial, peak), graphic (static, animated) and cancer (lung, melanoma). ANOVAs revealed that melanoma was more believable than lung cancer with static graphics at the establisher and peak; narratives were more believable with animated graphics at the peak segment; melanoma elicited greater positive attitudes; graphics in the peak influenced greatest intentions. Animated graphics visually framed to emphasise information at the establisher and peak segments suggest maximum effectiveness.

The goal of computer tailored health communications (CTHC) is to promote healthy behaviors by sending messages tailored to individual patients. Current CTHC systems collect baseline patient "profiles" and then use expert-written, rule-based systems to target messages to subsets of patients. Our main interest in this work is the study of collaborative filtering-based CTHC systems that can learn to tailor future message selections to individual patients based explicit feedback about past message selections. This paper reports the results of a study designed to collect explicit feedback (ratings) regarding four aspects of messages from 100 subjects in the smoking cessation support domain. Our results show that most users have positive opinions of most messages and that the ratings for all four aspects of the messages are highly correlated with each other. Finally, we conduct a range of rating prediction experiments comparing several different model variations. Our results show that predicting future ratings based on each user's past ratings contributes the most to predictive accuracy.

Centers for Disease Control and Prevention guidelines recommend follow-up within 72 hours of diagnosis of pelvic inflammatory disease because patients with inadequate treatment are at increased risk of acute and chronic complications. Follow-up rates in adolescents after diagnosis range between 10% and 16%. The primary objective is to assess the effect of text message reminders to adolescent patients receiving a diagnosis of pelvic inflammatory disease on obtaining follow-up care within 72 hours of emergency department (ED) discharge. This was a single-blinded randomized controlled trial of adolescents receiving a diagnosis of pelvic inflammatory disease in the ED. Patients received standard discharge instructions or standard discharge instructions plus text message reminders. Patients in the text message group received daily, tailored text messages for 4 days, with a reminder to schedule and attend primary care provider follow-up. The primary outcome was follow-up within 72 hours of ED discharge. Ninety-five patients (48 standard; 47 text message) were randomized. Three patients were excluded, leaving 92 patients (46 standard; 46 text message) for analysis. Baseline characteristics were similar between treatment groups. Follow-up was 15.2% in the standard group and 43.5% in the text message group. Patients receiving text message reminders were more likely to follow up compared with the standard group (relative risk 2.9; 95% confidence interval [CI] 1.4 to 5.7). The absolute efficacy difference was 28.3% (95% CI 9.5% to 46.9%), yielding number needed to treat of 4 (95% CI 2.2 to 9.5). Personalized text message reminders were efficacious in improving follow-up for adolescents after ED diagnosis of pelvic inflammatory disease.

A method for passing remote messages in a parallel computer system formed as a network of interconnected compute nodes includes that a first compute node (A) sends a single remote message to a remote second compute node (B) in order to control the remote second compute node (B) to send at least one remote message. The method includes various steps including controlling a DMA engine at first compute node (A) to prepare the single remote message to include a first message descriptor and at least one remote message descriptor for controlling the remote second compute node (B) to send at least one remote message, including putting the first message descriptor into an injection FIFO at the first compute node (A) and sending the single remote message and the at least one remote message descriptor to the second compute node (B).

The impact of health message framing on cervical cancer screening uptake is poorly understood. In a prospective randomized control study with 748 females, aged 21-65 years with no Pap smear in the previous 3 years, they randomly received a loss-framed, gain-framed, or neutral health message (control) regarding cervical cancer screening by email. Screening rate in the control group was 9.58 percent (CI: 9.29%-9.87%), 5.71 percent (CI: 5.48%-6.98%) in the gain-framed group, and 8.53 percent (CI: 8.24%-8.81%) in the loss-framed group. Statistically there was no difference between the three screening rates. Framing of health messages may not be a significant consideration when communicating through emails.

Full Text Available This 21st century will witness great advances in science and technology, many of which are certain to improve quality of life. Though numerous advances provide benefits, we still face the challenge of infectious diseases, which emerge or remerge, naturally or otherwise. The outbreak of the Ebola virus disease in West Africa at the end of 2013 is a case in point. It has continued for over a year and spread from the known origin of Guinea to neighboring countries, and reached the United States, Europe, and Asia through international travel. This outbreak accelerated translational research on vaccines and practical therapeutics. Thus, basic research paved the way for translational medicine. The driver for translational medicine is human health needs. In the era of the Internet, it is inevitable that people take full advantage of all this powerful tool can offer. The most obvious feature of the Internet age is the free sharing of knowledge and other information. In this regard, there is a need for a platform to share knowledge about infectious diseases and translational medicine. This journal, Infectious Diseases and Translational Medicine (IDTM, was designed to meet this requirement. We editors hope that this new journal will help our colleagues in exchanging ideas and bridging the gaps between basic research and translational medicine. We also hope that our readers will help in sharing their efforts with their colleagues by means of this platform. IDTM is a peer-reviewed, double-blinded, open-access, high-quality platform for online publication in both PDF and HTML formats. The journal is devoted to basic, applied, and translational research of infectious diseases. It includes diagnostics, therapeutics, and preventive countermeasures as well as related basic research, focusing on genomics, proteomics, and other omics-driven research to examine such areas as evolution, pathogenesis, and epidemiology. Here, we are formally announcing the launch of
Background The purpose of this article is to give an integrative insight into the theoretical and empirical-based development of the Online Pestkoppenstoppen (Stop Bullies Online/Stop Online Bullies). This intervention aims to reduce the number of cyberbully victims and their symptoms of depression and anxiety (program goal), by teaching cyberbully victims how to cope in an adequate and effective manner with cyberbully incidents (program’s outcomes). Method/Design In developing the program the different steps of the Intervention Mapping protocol are systematically used. In this article we describe each step of Intervention Mapping. Sources used for the development were a literature review, a Delphi study among experts, focus group interviews with the target group, and elements from a proven effective anti-bullying program. The result is a fully automated web-based tailored intervention for cyberbully victims (12-15 years) consisting of three web-based advice sessions delivered over three months. The first advice aims to teach participants how behavior is influenced by the thoughts they have, how to recognize and dispute irrational thoughts and how to form rational thoughts. In the second advice, participants will learn about the way bullying emerges, how their behavior influences bullying and how they can use effective coping strategies in order to stop (online) bullying. In the third advice, participants receive feedback and will learn how to use the Internet and mobile phones in a safe manner. Each advice is tailored to the participant’s personal characteristics (e.g., personality, self-efficacy, coping strategies used and (ir)rational thoughts). To ensure implementation of the program after testing it for effectiveness, the intervention was pretested in the target-population and an implementation plan was designed. Finally, we will elaborate on the planned randomized controlled trial in which the intervention will be compared to a general information group

In the light of the broad variation in US high-level waste (HLW) types and the uncertainties in future waste production, research on the Rockwell International Science Center has focussed on developing a generic technology for the consolidation of high-level wastes into polyphase ceramics. The basic approach has been to 'tailor' wste compositions with chemical additives so that upon consolidation a dense ceramic assemblage is formed that chemically binds the waste species into known phases. This chapter deals with tailored ceramics for current and future high-level waste compositions. Section 2 gives a historical review of the development of tailored ceramics. Section 3 deals with tailored ceramics designed for specific HLW compositions and with microstructure and phase development. Section 4 discusses chemical and physical properties of tailored ceramic waste forms. In section 5 the various processing steps involved in converting HLW to polycrystalline ceramic forms are described. (author). 159 refs.; 20 figs.; 14 tabs

Persuasive messages are more effective when they are custom-tailored to reflect the interests and concerns of the intended audience. Much of the message-framing literature has focused on the advantages of using either gain or loss frames, depending on the motivational orientation of the target group. In the current study, we extended this research to examine whether a persuasive appeal's effectiveness can be increased by aligning the message framing with the recipient's personality profile. For a single product, we constructed five advertisements, each designed to target one of the five major trait domains of human personality. In a sample of 324 survey respondents, advertisements were evaluated more positively the more they cohered with participants' dispositional motives. These results suggest that adapting persuasive messages to the personality traits of the target audience can be an effective way of increasing the messages' impact, and highlight the potential value of personality-based communication strategies.
The SPHERE Study. Secondary prevention of heart disease in general practice: protocol of a randomised controlled trial of tailored practice and patient care plans with parallel qualitative, economic and policy analyses. [ISRCTN24081411
Full Text Available Abstract Background The aim of the SPHERE study is to design, implement and evaluate tailored practice and personal care plans to improve the process of care and objective clinical outcomes for patients with established coronary heart disease (CHD in general practice across two different health systems on the island of Ireland. CHD is a common cause of death and a significant cause of morbidity in Ireland. Secondary prevention has been recommended as a key strategy for reducing levels of CHD mortality and general practice has been highlighted as an ideal setting for secondary prevention initiatives. Current indications suggest that there is considerable room for improvement in the provision of secondary prevention for patients with established heart disease on the island of Ireland. The review literature recommends structured programmes with continued support and follow-up of patients; the provision of training, tailored to practice needs of access to evidence of effectiveness of secondary prevention; structured recall programmes that also take account of individual practice needs; and patient-centred consultations accompanied by attention to disease management guidelines. Methods SPHERE is a cluster randomised controlled trial, with practice-level randomisation to intervention and control groups, recruiting 960 patients from 48 practices in three study centres (Belfast, Dublin and Galway. Primary outcomes are blood pressure, total cholesterol, physical and mental health status (SF-12 and hospital re-admissions. The intervention takes place over two years and data is collected at baseline, one-year and two-year follow-up. Data is obtained from medical charts, consultations with practitioners, and patient postal questionnaires. The SPHERE intervention involves the implementation of a structured systematic programme of care for patients with CHD attending general practice. It is a multi-faceted intervention that has been developed to respond to

Tailoring of porous materials involves not only chemical synthetic techniques for tailoring microscopic properties such as pore size, pore shape, pore connectivity, and pore surface reactivity, but also materials processing techniques for tailoring the meso- and the macroscopic properties of bulk materials in the form of fibers, thin films and monoliths. These issues are addressed in the context of five specific classes of porous materials: oxide molecular sieves, porous coordination solids, porous carbons, sol-gel derived oxides, and porous heteropolyanion salts. Reviews of these specific areas are preceded by a presentation of background material and review of current theoretical approaches to adsorption phenomena. A concluding section outlines current research needs and opportunities.

Background Few studies have tested whether individually tailored text messaging interventions have an effect on clinical outcomes when used to supplement traditional psychotherapy. This is despite the potential to improve outcomes through symptom monitoring, prompts for between-session activities, and psychoeducation. Objective The intent of the study was to explore the use of individually tailored between-session text messaging, or short message service (SMS), as an adjunct to telephone-base...
To further develop tailored interventions, their working mechanisms must be identified. In the present study, three tailored messages that each contained one potential working mechanism-personalization, adaptation or feedback-were compared with a standard information condition. Two hundred and two

The now ubiquitous catchphrase, "There's an app for that," rings true owing to the growing number of mobile phone apps. In excess of 97,000 eHealth apps are available in major app stores. Yet the effectiveness of these apps varies greatly. While a minority of apps are developed grounded in theory and in conjunction with health care experts, the vast majority are not. This is concerning given the Hippocratic notion of "do no harm." There is currently no unified formal theory for developing interactive eHealth apps, and development is especially difficult when complex messaging is required, such as in health promotion and prevention. This paper aims to provide insight into the creation of interactive eHealth apps for complex messaging, by leveraging the Safe-D case study, which involved complex messaging required to guide safe but sufficient UV exposure for vitamin D synthesis in users. We aim to create recommendations for developing interactive eHealth apps for complex messages based on the lessons learned during Safe-D app development. For this case study we developed an Apple and Android app, both named Safe-D, to safely improve vitamin D status in young women through encouraging safe ultraviolet radiation exposure. The app was developed through participatory action research involving medical and human computer interaction researchers, subject matter expert clinicians, external developers, and target users. The recommendations for development were created from analysis of the development process. By working with clinicians and implementing disparate design examples from the literature, we developed the Safe-D app. From this development process, recommendations for developing interactive eHealth apps for complex messaging were created: (1) involve a multidisciplinary team in the development process, (2) manage complex messages to engage users, and (3) design for interactivity (tailor recommendations, remove barriers to use, design for simplicity). This research has

Two experiments investigated the processes through which post-message behavior (e.g., noncompliance) influences resistance to the message. Participants in Experiment 1 read preventive, consumer-education messages that either opposed the consumption of an alcohol-like product or recommended moderation. Half of the participants then tried the product, whereas the remaining participants performed a filler task. In the absence of trial, the two messages had the same effect. However, recipients of the abstinence-promoting preventive message who tried the product had stronger intentions to use the product in the future than recipients of the moderation message. This finding suggests that assessments of message impact may be inadequate unless an opportunity for trial is also provided. Results are interpreted in terms of self-perception and cognitive dissonance and contrasted from psychological reactance.

Using Community-based and Tribal Participatory Research (CBPR/TPR) approaches, an academic-tribal partnership between the University of Washington Alcohol and Drug Abuse Institute and the Suquamish and Port Gamble S'Klallam Tribes developed a culturally grounded social skills intervention to promote increased cultural belonging and prevent substance abuse among tribal youth. Participation in the intervention, which used the Canoe Journey as a metaphor for life, was associated with increased hope, optimism, and self-efficacy and with reduced substance use, as well as with higher levels of cultural identity and knowledge about alcohol and drugs among high school-age tribal youth. These results provide preliminary support for the intervention curricula in promoting positive youth development, an optimistic future orientation, and the reduction of substance use among Native youth.

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

The task to provide service to users who employ various kinds of procedures in sending and receiving messages over terminal devices of different types presents a formidable challenge. In order to meet this challenge, it was necessary to develop a TRI-TAC system architecture with special characteristics which made it possible to process reliably narrative, data, and graphic messages even in an environment of high circuit noise and degradated signals. The present paper is concerned with the architectural considerations involved in the techniques which are utilized to handle message traffic in the tactical area.

Gambling warning messages have been shown to lead to prevention and modification of risk-taking behaviors. Laboratory studies have shown messages can increase a player's knowledge about gambling specific risks, modify their gambling-related cognitive distortions, and even change play. In the present laboratory study, participants were randomly assigned to a winning or losing slot machine gambling experience where they either viewed periodic warning messages or not. It was hypothesized that those in the message conditions would place smaller bets, spend more time considering bets, and spend less time gambling than those in the control conditions. We also hypothesized participants would play differently across the contexts of winning or losing. The results showed those who received warning messages while winning made the fewest number of spins and did not speed up their bet rate over the course of play as much as those in other conditions. Players who received warning messages while losing decreased the size of their bets over the course of play compared to those who received messages while winning. Despite receiving warning messages, losing players did not decrease their number of spins or rate of betting. Winning or losing during slot machine play appears to have significant consequences on the impact of a warning message. Whereas a message to change gambling behavior may encourage a winning gambler to stop play, the same message for a losing player may lead to a small minimization in harm by helping them to decrease bet size, though not their rate of betting.

Despite the effectiveness of psychosocial programs for recovery from drug use problems, there have been challenges in implementation of treatment. Internet-based and computerized approaches have been known to be effective in treatment dissemination. The study purpose is to assess the effects of a web-based psychosocial relapse prevention program with a multicenter randomized controlled trial. Recruitment began in January 2015 for outpatient participants diagnosed with drug abuse or dependence who have used a primary abused drug in the past year at psychiatric hospitals and a clinic. Participants are randomized either to a web-based relapse prevention program or a self-monitoring group. The intervention is a web-based relapse prevention program named "e-SMARPP" that consists of six relapse prevention program modules with tailored feedback from health care professionals and 8 weeks of self-monitoring. The content is adapted from a face-to-face relapse prevention program which is based on cognitive behavioral therapy and motivational enhancement. The primary outcomes are relapse risk assessed by the Stimulant Relapse Risk Scale (baseline, 2-, 5- and 8-month) and the longest duration of consecutive abstinent days from primary abused drug during the intervention. Secondary outcomes will include motivation to change, self-efficacy for drug use and craving, abstinent days in the past 28 or 56 days, quality of life, sense of coherence, cost of substance use, medical cost, retention of treatment and use of self-help group. Completion, usability and satisfaction of the program will be also assessed to explore feasibility. This study protocol was approved by the Ethics Committee of The University of Tokyo and each recruiting hospital and clinic. To our knowledge, this study is the first clinical trial to assess the effects of a web-based therapeutic program for drug users in Japan. If successful, this program is a promising approach for drug user treatment in Japan, where the
Full Text Available In this study, we demonstrate that the art infusion effect, in which the presence of visual art causes a positive impact on consumers’ perceptions of products and advertising messages, might have a moderation effect on regulatory fit and non-fit messages. We investigate the impact of visual art on advertisement evaluations in regulatory (non- fit conditions. Regulatory focus theory suggests that consumers rely on their motivational focus (prevention vs. promotion for their evaluations and decisions. Usually, consumers prefer products that fit with their personal motivational focus. In the present study, the results of three experiments indicate that using visual art with a promotion or prevention fit message is recommended, while non-art images increase message persuasiveness when non-fit messages are presented. Therefore, not all information compatible with the consumer’s motivational focus are best evaluated. When non-art images are presented, non-fit messages might be more persuasive.

Background Health risk assessments with tailored feedback plus health education have been shown to be effective for promoting health behavior change. However, there is limited evidence to guide the development and delivery of online automated tailored feedback. Objective The goal of this study was to optimize tailored feedback messages for an online health risk assessment to promote enhanced user engagement, self-efficacy, and behavioral intentions for engaging in healthy behaviors. We examined the effects of three theory-based message factors used in developing tailored feedback messages on levels of engagement, self-efficacy, and behavioral intentions. Methods We conducted a randomized factorial experiment to test three different components of tailored feedback messages: tailored expectancy priming, autonomy support, and use of an exemplar. Individuals (N=1945) were recruited via Amazon Mechanical Turk and randomly assigned to one of eight different experimental conditions within one of four behavioral assessment and feedback modules (tobacco use, physical activity [PA], eating habits, and weight). Participants reported self-efficacy and behavioral intentions pre- and postcompletion of an online health behavior assessment with tailored feedback. Engagement and message perceptions were assessed at follow-up. Results For the tobacco module, there was a significant main effect of the exemplar factor (P=.04); participants who received exemplar messages (mean 3.31, SE 0.060) rated their self-efficacy to quit tobacco higher than those who did not receive exemplar messages (mean 3.14, SE 0.057). There was a three-way interaction between the effect of message conditions on self-efficacy to quit tobacco (P=.02), such that messages with tailored priming and an exemplar had the greatest impact on self-efficacy to quit tobacco. Across PA, eating habits, and weight modules, there was a three-way interaction among conditions on self-efficacy (P=.048). The highest self

A direct connection between certain lifestyle factors and an increased risk of cancer has already been established. Despite well-documented associations, controversial messages on causes of cancer often appear without taking into consideration their impact on the general population. While mainstream coverage of cancer research is clearly welcome, consideration must be given to the risk of transmitting provocative messages with serious negative consequences for cancer research and public health. We must avoid becoming a breeding ground for the misinterpretation of scientific information. Polemical results can stimulate scientific research and progress, but controversial messages encourage confusion and impotence in an increasingly disoriented population. The correct communication of health messages is at least as important as research on risk factors.

-planned subgroup analyses based on the type of message (screening, prevention, and treatment). The primary outcome was behaviour. We did not assess any adverse outcomes. We included 35 studies involving 16,342 participants (all health consumers) and reporting 51 comparisons.In the context of attribute framing, participants in one included study understood the message better when it was framed negatively than when it was framed positively (1 study; SMD -0.58 (95% confidence interval (CI) -0.94 to -0.22); moderate effect size; low quality evidence). Although positively-framed messages may have led to more positive perception of effectiveness than negatively-framed messages (2 studies; SMD 0.36 (95% CI -0.13 to 0.85); small effect size; low quality evidence), there was little or no difference in persuasiveness (11 studies; SMD 0.07 (95% CI -0.23 to 0.37); low quality evidence) and behavior (1 study; SMD 0.09 (95% CI -0.14 to 0.31); moderate quality evidence).In the context of goal framing, loss messages led to a more positive perception of effectiveness compared to gain messages for screening messages (5 studies; SMD -0.30 (95% CI -0.49 to -0.10); small effect size; moderate quality evidence) and may have been more persuasive for treatment messages (3 studies; SMD -0.50 (95% CI -1.04 to 0.04); moderate effect size; very low quality evidence). There was little or no difference in behavior (16 studies; SMD -0.06 (95% CI -0.15 to 0.03); low quality evidence). No study assessed the effect on understanding. Contrary to commonly held beliefs, the available low to moderate quality evidence suggests that both attribute and goal framing may have little if any consistent effect on health consumers' behaviour. The unexplained heterogeneity between studies suggests the possibility of a framing effect under specific conditions. Future research needs to investigate these conditions.

Previous research has found that smoking cessation messages can be designed to appear as tailored (placebo tailored) and result in superior outcomes compared to standard messages. In the current study, we aimed (a) to test the efficacy of placebo tailoring for smoking cessation and (b) to examine the influence of cognitive processing style. In a 2-arm randomized controlled trial, 424 smokers (M = 19.66 cigarettes per day) from the community (57% female, 30% Caucasian, 40% African American, 29% Hispanic; mean age = 42 years) were randomly assigned to receive 4 placebo-tailored booklets or 4 standard booklets over 3 months. Participants completed a measure of systematic versus heuristic cognitive processing style at baseline. The primary outcome was 7-day point prevalence abstinence (ppa). Twenty-eight-day continuous abstinence, content evaluations, and readiness to quit were secondary outcomes. We hypothesized that placebo tailoring would be superior to standard materials and that the effect would be moderated by cognitive processing style (systematic and heuristic). As expected, placebo tailoring led to greater 7-day ppa at 3 months and greater 28-day continuous abstinence at 6 months. Cognitive processing style moderated the effect on 7-day ppa, such that the placebo-tailored booklets produced greater cessation among participants with heuristic information processing tendencies. Findings support a causal role of placebo tailoring for short-term smoking cessation, particularly for individuals who process information using heuristic strategies. Implications for tailored interventions are discussed.

This research investigates how the impact of persuasive messages in the political domain can be improved when fit is created by subliminally priming recipients' regulatory focus (either promotion or prevention) and by linguistic framing of the message (either strategic approach framing or strategic avoidance framing). Results of two studies show that regulatory fit: a) increases the impact of a political message favoring nuclear energy on implicit attitudes of the target audience (Study 1); and b) induces a more positive evaluation of, and intentions to vote for, the political candidate who is delivering a message concerning immigration policies (Study 2).

Tailored graph ensembles are a developing bridge between biological networks and statistical mechanics. The aim is to use this concept to generate a suite of rigorous tools that can be used to quantify and compare the topology of cellular signalling networks, such as protein-protein interaction networks and gene regulation networks. We calculate exact and explicit formulae for the leading orders in the system size of the Shannon entropies of random graph ensembles constrained with degree distribution and degree-degree correlation. We also construct an ergodic detailed balance Markov chain with non-trivial acceptance probabilities which converges to a strictly uniform measure and is based on edge swaps that conserve all degrees. The acceptance probabilities can be generalized to define Markov chains that target any alternative desired measure on the space of directed or undirected graphs, in order to generate graphs with more sophisticated topological features.
Message interpretation, the notion that individuals assign meaning to stimuli, is related to listening presage, listening process, and listening product. As a central notion of communication, meaning includes (a) denotation and connotation, and (b) content and relational meanings, which can vary in ambiguity and vagueness. Past research on message…

CONVERGENCE is a French multi-partner national project designed to gather HPC and informatics expertise to innovate in the context of running French global climate models with differing grids and at differing resolutions. Efficient and reliable execution of these models and the management and dissemination of model output are some of the complexities that CONVERGENCE aims to resolve.At any one moment in time, researchers affiliated with the Institut Pierre Simon Laplace (IPSL) climate modeling group, are running hundreds of global climate simulations. These simulations execute upon a heterogeneous set of French High Performance Computing (HPC) environments. The IPSL's simulation execution runtime libIGCM (library for IPSL Global Climate Modeling group) has recently been enhanced so as to support hitherto impossible realtime use cases such as simulation monitoring, data publication, metrics collection, simulation control, visualizations … etc. At the core of this enhancement is Prodiguer: an AMQP (Advanced Message Queue Protocol) based event driven asynchronous distributed messaging platform. libIGCM now dispatches copious amounts of information, in the form of messages, to the platform for remote processing by Prodiguer software agents at IPSL servers in Paris. Such processing takes several forms: Persisting message content to database(s); Launching rollback jobs upon simulation failure; Notifying downstream applications; Automation of visualization pipelines; We will describe and/or demonstrate the platform's: Technical implementation; Inherent ease of scalability; Inherent adaptiveness in respect to supervising simulations; Web portal receiving simulation notifications in realtime.

Abstract Background: With the increasing penetration of digital mobile devices among adolescents, mobile texting messaging is emerging as a new channel for patient–clinician communication for this population. In particular, it can promote active communication between healthcare clinicians and adolescents with asthma. However, little is known about the content of the messages exchanged in medical encounters via mobile text messaging. Therefore, this study explored the content of text messaging between clinicians and adolescents with asthma. Materials and Methods: We collected a total of 2,953 text messages exchanged between 5 nurse case managers and 131 adolescents with asthma through a personal digital assistant. The text messages were coded using a scheme developed by adapting categories from the Roter Interaction Analysis System. Results: Nurse case managers sent more text messages (n=2,639) than adolescents with asthma. Most messages sent by nurse case managers were targeted messages (n=2,475) directed at all adolescents with asthma, whereas there were relatively few tailored messages (n=164) that were created personally for an individual adolescent. In addition, both targeted and tailored messages emphasized task-focused behaviors over socioemotional behaviors. Likewise, text messages (n=314) sent by adolescents also emphasized task-focused over socioemotional behaviors. Conclusions: Mobile texting messaging has the potential to play an important role in patient–clinician communication. It promotes not only active interaction, but also patient-centered communication with clinicians. In order to achieve this potential, healthcare clinicians may need to focus on socioemotional communication as well as task-oriented communication. PMID:25401324

Art has been shown to be an empowering and engaging entity with numerous benefits to vulnerable populations, including the homeless persons and young adults. However, little is known how homeless young adults perceive the use of art as messages that can communicate the danger of initiating or continuing drug and alcohol use. The purpose of this study was to solicit perspectives of homeless, drug-using young adults as to how art can be used to design messages for their peers about the danger of initiating or continuing drug and alcohol use. Qualitative methodology via focus group discussions was utilized to engage 24 homeless young adults enrolled from a drop-in site in Santa Monica, California. The findings revealed support for a myriad of delivery styles, including in-person communication, flyers, music, documentary film, and creative writing. The young adults also provided insight into the importance of the thematic framework of messages. Such themes ranged from empowering and hopeful messages to those designed to scare young homeless adults into not experimenting with drugs. The findings indicate that in addition to messages communicating the need to prevent or reduce drug and alcohol use, homeless young adults respond to messages that remind them of goals and dreams they once had for their future, and to content that is personal, real, and truthful. Our research indicates that messages that reinforce protective factors such as hope for the future and self-esteem may be as important to homeless young adults as information about the risks and consequences of drug use.

Walking is among the most cost-effective and accessible means of exercise. Mounting evidence suggests that walking may help to maintain physical and cognitive independence in old age by preventing a variety of health problems. However, older Americans fall far short of meeting the daily recommendations for walking. In 2 studies, we examined whether considering older adults' preferential attention to positive information may effectively enhance interventions aimed at promoting walking. In Study 1, we compared the effectiveness of positive, negative, and neutral messages to encourage walking (as measured with pedometers). Older adults who were informed about the benefits of walking walked more than those who were informed about the negative consequences of failing to walk, whereas younger adults were unaffected by framing valence. In Study 2, we examined within-person change in walking in older adults in response to positively- or negatively-framed messages over a 28-day period. Once again, positively-framed messages more effectively promoted walking than negatively-framed messages, and the effect was sustained across the intervention period. Together, these studies suggest that consideration of age-related changes in preferences for positive and negative information may inform the design of effective interventions to promote healthy lifestyles. Future research is needed to examine the mechanisms underlying the greater effectiveness of positively- as opposed to negatively-framed messages and the generalizability of findings to other intervention targets and other subpopulations of older adults.

This systematic review explores how computer-tailored, behavioral interventions implemented and delivered via the Web have been operationalized in a variety of settings. Computer-tailored, online behavioral intervention studies published from 1996 to early 2007 were selected and reviewed by two independent coders. Of 503 studies screened, 30 satisfied the selection criteria. The level of sophistication of these interventions varied from immediate risk/health assessment, tailored web content to full-blown customized health programs. The most common variables for tailoring content were health behaviors and stages of change. Message tailoring was achieved through a combination mechanisms including: feedback, personalization and adaptation. Tailored, self-guided health interventions delivered via the Web to date have involved a great diversity of features and formats. While some programs have been relatively brief and simple, others have involved complex, theory-based tailoring with iterative assessment, tools for development of self-regulatory skills, and various mechanisms for providing feedback. Our ability to fully optimize the use of computer-assisted tailoring will depend on the development of empirically based guidelines for tailoring across populations, health foci, health behaviors and situations. Further outcome research is needed to enhance our understanding of how and under what conditions computer-tailoring leads to positive health outcomes in online behavioral interventions.

In preparation for NOvA, a future neutrino experiment at Fermilab, we are developing a system for passing control and status messages in the data acquisition system. The DAQ system will consist of applications running on approximately 450 nodes. The message passing system will use a publish-subscribe model and will provide support for sending messages and receiving the associated replies. Additional features of the system include a layered architecture with custom APIs tailored to the needs of a DAQ system, the use of an open source messaging system for handling the reliable delivery of messages, the ability to send broadcasts to groups of applications, and APIs in Java, C++, and Python. Our choice for the open source system to deliver messages is EPICS. We will discuss the architecture of the system, our experience with EPICS, and preliminary test results

The Remote Asynchronous Message Service (RAMS) gateway is a special-purpose AMS application node that enables exchange of AMS messages between nodes residing in different AMS "continua," notionally in different geographical locations. JPL s implementation of RAMS gateway functionality is integrated with the ION (Interplanetary Overlay Network) implementation of the DTN (Delay-Tolerant Networking) bundle protocol, and with JPL s implementation of AMS itself. RAMS protocol data units are encapsulated in ION bundles and are forwarded to the neighboring RAMS gateways identified in the source gateway s AMS management information base. Each RAMS gateway has interfaces in two communication environments: the AMS message space it serves, and the RAMS network - the grid or tree of mutually aware RAMS gateways - that enables AMS messages produced in one message space to be forwarded to other message spaces of the same venture. Each gateway opens persistent, private RAMS network communication channels to the RAMS gateways of other message spaces for the same venture, in other continua. The interconnected RAMS gateways use these communication channels to forward message petition assertions and cancellations among themselves. Each RAMS gateway subscribes locally to all subjects that are of interest in any of the linked message spaces. On receiving its copy of a message on any of these subjects, the RAMS gateway node uses the RAMS network to forward the message to every other RAMS gateway whose message space contains at least one node that has subscribed to messages on that subject. On receiving a message via the RAMS network from some other RAMS gateway, the RAMS gateway node forwards the message to all subscribers in its own message space.

Health messages on television and other mass media have the potential to significantly influence the public's health-related knowledge and behaviors, but little is known about people's ability to comprehend such messages. To investigate whether people understood the spoken information in media messages about cancer prevention and screening, we recruited 44 adults from 3 sites to view 6 messages aired on television and the internet. Participants were asked to paraphrase main points and selected phrases. Qualitative analysis methods were used to identify what content was correctly and accurately recalled and paraphrased, and to describe misunderstandings and misconceptions. While most participants accurately recalled and paraphrased the gist of the messages used here, overgeneralization (e.g., believing preventative behaviors to be more protective than stated), loss of details (e.g., misremembering the recommended age for screening), and confusion or misunderstandings around specific concepts (e.g., interpreting "early stage" as the stage in one's life rather than cancer stage) were common. Variability in the public's ability to understand spoken media messages may limit the effectiveness of both pubic health campaigns and provider-patient communication. Additional research is needed to identify message characteristics that enhance understandability and improve comprehension of spoken media messages about cancer.

With this issue’s message, Fermilab Director Pier Oddone opens a new series of occasional exchanges between CERN and other laboratories world-wide. As part of this exchange, CERN Director-General Rolf Heuer, wrote a message in Tuesday’s edition of Fermilab TodayPerspectivesNothing is more important for our worldwide particle physics community than successfully turning on the LHC later this year. The promise for great discoveries is huge, and many of the plans for our future depend on LHC results. Those of us planning national programmes in anticipation of data from the LHC face formidable challenges to develop future facilities that are complementary to the LHC, whatever the physics discoveries may be. At Fermilab, this has led us to move forcefully with a programme at the intensity frontier, where experiments with neutrinos and rare decays open a complementary window into nature.

Few studies have tested whether individually tailored text messaging interventions have an effect on clinical outcomes when used to supplement traditional psychotherapy. This is despite the potential to improve outcomes through symptom monitoring, prompts for between-session activities, and psychoeducation. The intent of the study was to explore the use of individually tailored between-session text messaging, or short message service (SMS), as an adjunct to telephone-based psychotherapy for consumers who present to the Emergency Department (ED) in situational and/or emotional crises. Over a 4-month period, two therapists offered 68 prospective consumers of a telephone-based psychotherapy service individually tailored between-session text messaging alongside their telephone-based psychotherapy. Attendance and clinical outcomes (depression, anxiety, functional impairment) of those receiving messages were compared against a historical control group (n=157) who received telephone psychotherapy only. A total of 66% (45/68) of the consumers offered SMS accepted the intervention. A total of 432 messages were sent over the course of the trial, the majority involving some kind of psychoeducation or reminders to engage in therapy goals. There were no significant differences in clinical outcomes between consumers who received the SMS and those in the control group. There was a trend for participants in the intervention group to attend fewer sessions than those in the control group (mean 3.7, SD 1.9 vs mean 4.4, SD 2.3). Both groups showed significant improvement over time. Individually tailored SMS were not found to improve clinical outcomes in consumers receiving telephone-based psychotherapy, but the study was underpowered, given the effect sizes noted and the significance level chosen. Given the ease of implementation and positive feedback from therapists and clients, individually tailored text messages should be explored further in future trials with a focus on enhancing

While Web-based interventions can be efficacious, engaging a target population's attention remains challenging. We argue that strategies to draw such a population's attention should be tailored to meet its needs. Increasing user engagement in online suicide intervention development requires feedback from this group to prevent people who have suicide ideation from seeking treatment. The goal of this study was to solicit feedback on the acceptability of the content of messaging from social media users with suicide ideation. To overcome the common concern of lack of engagement in online interventions and to ensure effective learning from the message, this research employs a customized design of both content and length of the message. In study 1, 17 participants suffering from suicide ideation were recruited. The first (n=8) group conversed with a professional suicide intervention doctor about its attitudes and suggestions for a direct message intervention. To ensure the reliability and consistency of the result, an identical interview was conducted for the second group (n=9). Based on the collected data, questionnaires about this intervention were formed. Study 2 recruited 4222 microblog users with suicide ideation via the Internet. The results of the group interviews in study 1 yielded little difference regarding the interview results; this difference may relate to the 2 groups' varied perceptions of direct message design. However, most participants reported that they would be most drawn to an intervention where they knew that the account was reliable. Out of 4222 microblog users, we received responses from 725 with completed questionnaires; 78.62% (570/725) participants were not opposed to online suicide intervention and they valued the link for extra suicide intervention information as long as the account appeared to be trustworthy. Their attitudes toward the intervention and the account were similar to those from study 1, and 3 important elements were found

Full Text Available The transport message security provided by vehicles in VANETs is quite important; vehicle message should be real-time and it will be not complicated to validate message calculation. The method proposed in the essay is mainly to validate the identity by means of Bilinear Diffie-Hellman method, and make vehicles validate the authenticity of RSU and TA’s identity and the effectiveness of key. RSU and TA only need to validate vehicle identity, without helping vehicles produce any key. When vehicle identity validation is completed, vehicles will produce public value and transmit it to other RSU and vehicles, while other vehicles could validate the identity through the message from the sender and public value from RSU. The advantages of the method proposed in this essay are listed as follows. (1 Vehicles, RSU, and TA can validate mutual identities and the effectiveness of keys. (2 Vehicles can produce public value functions automatically, thus reducing key control risks. (3 Vehicles do not need to show certificates to validate their identities, preventing the certificates from attacking because of long-term exposure. (4 Vehicles adopt a pseudonym ID challenge to validate their own identities during the process of handoff. (5 Vehicle messages can be validated using the Bilinear Diffie-Hellman (BDH method without waiting for the RSU to validate messages, thus improving the instantaneity of messaging. The method proposed in the essay can satisfy source authentication, message integrity, nonrepudiation, privacy, and conditional untraceability requirements.

Family health history reflects the effects of genetic, environmental, and behavioral factors and is an important risk factor for a variety of disorders including coronary heart disease, cancer, and diabetes. In 2004, the Centers for Disease Control and Prevention developed Family Healthware, a new interactive, Web-based tool that assesses familial risk for 6 diseases (coronary heart disease, stroke, diabetes, and colorectal, breast, and ovarian cancer) and provides a "prevention plan" with personalized recommendations for lifestyle changes and screening. The tool collects data on health behaviors, screening tests, and disease history of a person's first- and second-degree relatives. Algorithms in the software analyze the family history data and assess familial risk based on the number of relatives affected, their age at disease onset, their sex, how closely related the relatives are to each other and to the user, and the combinations of diseases in the family. A second set of algorithms uses the data on familial risk level, health behaviors, and screening to generate personalized prevention messages. Qualitative and quantitative formative research on lay understanding of family history and genetics helped shape the tool's content, labels, and messages. Lab-based usability testing helped refine messages and tool navigation. The tool is being evaluated by 3 academic centers by using a network of primary care practices to determine whether personalized prevention messages tailored to familial risk will motivate people at risk to change their lifestyles or screening behaviors.

Results of ongoing scientific research on environmental determinants of breast cancer are not typically presented to the public in ways they can easily understand and use to take preventive actions. In this study, results of scientific studies on progesterone exposure as a risk factor for breast cancer were translated into high and low literacy level messages. Using the heuristic systematic model, this study examined how ability, motivation, and message processing (heuristic and systematic) influenced perceptions of risk beliefs and negative attitudes about progesterone exposure among women who read the translated scientific messages. Among the 1254 participants, those given the higher literacy level message had greater perceptions of risk about progesterone. Heuristic message cues of source credibility and perceived message quality, as well as motivation, also predicted risk beliefs. Finally, risk beliefs were a strong predictor of negative attitudes about exposure to progesterone. The results can help improve health education message design in terms of practitioners having better knowledge of message features that are the most persuasive to the target audiences on this topic.

During the EGEE-III project operational tools such as SAM, Nagios, Gridview, the regional Dashboard and GGUS moved to a communication architecture based on ActiveMQ, an open-source enterprise messaging solution. LHC experiments, in particular ATLAS, developed prototypes of systems using the same messaging infrastructure, validating the system for their use-cases. In this paper we describe the WLCG messaging use cases and outline an improved messaging architecture based on the experience gained during the EGEE-III period. We show how this provides a solid basis for many applications, including the grid middleware, to improve their resilience and reliability.

We explored the attitudes, opinions, and concerns of African American women regarding influenza vaccination during pregnancy. As influenza immunization coverage rates remain suboptimal in the United States among this population, we elicited message framing strategies for multicomponent interventions aimed at decreasing future incident cases of maternal and neonatal influenza. Semi-structured in-depth interviews (N = 21) were conducted with pregnant African American women at urban OB/GYN clinics who had not received an influenza vaccine. Interviews were transcribed, subjected to intercoder reliability assessment, and content analyzed to identify common thematic factors related to acceptance of the influenza vaccine and health communication message preferences. Four major themes were identified. These were communication approaches, normal vaccine behavior, pregnancy vaccination, and positive versus negative framing. Two strong themes emerged: positively-framed messages were preferred over negatively-framed messages and those emphasizing the health of the infant. Additionally, previous immunization, message source, and vaccine misperceptions also played important roles in decision-making. The majority of women indicated that positively framed messages focusing on the infant's health would encourage them to receive an influenza vaccine. Messages emphasizing immunization benefits such as protection against preterm birth and low birth weight outcomes have potential to overcome widespread negative community perceptions and cultural beliefs. Additionally, messages transmitted via interpersonal networks and social media strongly influence motivation to obtain vaccination during pregnancy. The findings of this study will assist in developing tailored messages that change pregnant African American women's influenza vaccination decision-making to achieve improved coverage.

An increase in physical activity for secondary prevention of cardiovascular disease and cardiac rehabilitation has multiple therapeutic benefits, including decreased mortality. Internet- and mobile-based interventions for physical activity have shown promising results in helping users increase or maintain their level of physical activity in general and specifically in secondary prevention of cardiovascular diseases and cardiac rehabilitation. One component related to the efficacy of these interventions is tailoring of the content to the individual. Our trial assessed the effect of a longitudinally tailored Internet- and mobile-based intervention for physical activity as an extension of a face-to-face cardiac rehabilitation stay. We hypothesized that users of the tailored intervention would maintain their physical activity level better than users of the nontailored version. The study population included adult participants of a cardiac rehabilitation program in Norway with home Internet access and a mobile phone. The participants were randomized in monthly clusters to a tailored or nontailored (control) intervention group. All participants had access to a website with information regarding cardiac rehabilitation, an online discussion forum, and an online activity calendar. Those using the tailored intervention received tailored content based on models of health behavior via the website and mobile fully automated text messages. The main outcome was self-reported level of physical activity, which was obtained using an online international physical activity questionnaire at baseline, at discharge, and at 1 month and 3 months after discharge from the cardiac rehabilitation program. Included in the study were 69 participants. One month after discharge, the tailored intervention group (n=10) had a higher median level of overall physical activity (median 2737.5, IQR 4200.2) than the control group (n=14, median 1650.0, IQR 2443.5), but the difference was not significant

Preventive health messages are often tailored to reach broad sociodemographic groups. However, within groups, there may be considerable variation in perceptions of preventive health practices, such as colorectal cancer screening. Segmentation analysis provides a tool for crafting messages that are tailored more closely to the mental models of targeted individuals or subgroups. This study used cluster analysis, a psychosocial marketing segmentation technique, to develop a typology of colorectal cancer screening orientation among 102 African American clinic patients between the ages of 50 and 74 years with limited literacy. Patients were from a general internal medicine clinic in a large urban teaching hospital, a subpopulation known to have high rates of colorectal cancer and low rates of screening. Preventive screening orientation variables included the patients' responses to questions involving personal attitudes and preferences toward preventive screening and general prevention practices. A k-means cluster analysis yielded three clusters of patients on the basis of their screening orientation: ready screeners (50.0%), cautious screeners (30.4%), and fearful avoiders (19.6%). The resulting typology clearly defines important subgroups on the basis of their preventive health practice perceptions. The authors propose that the development of a validated typology of patients on the basis of their preventive health perceptions could be applicable to a variety of health concerns. Such a typology would serve to standardize how populations are characterized and would provide a more accurate view of their preventive health-related attitudes, values, concerns, preferences, and behaviors. Used with standardized assessment tools, it would provide an empirical basis for tailoring health messages and improving medical communication.

This research investigates how the impact of persuasive messages in the political domain can be improved when fit is created by subliminally priming recipients’ regulatory focus (either promotion or prevention) and by linguistic framing of the message (either strategic approach framing or strategic avoidance framing). Results of two studies show that regulatory fit: a) increases the impact of a political message favoring nuclear energy on implicit attitudes of the target audience (Study 1); and b) induces a more positive evaluation of, and intentions to vote for, the political candidate who is delivering a message concerning immigration policies (Study 2).

The 1994 Back to Sleep public education campaign resulted in dramatic reductions in sleep-related infant deaths, but comparable progress in recent years has been elusive. We conducted qualitative analyses of recent safe sleep campaigns from 13 U.S. cities. Goals were to (a) determine whether the campaigns reflect the full range of American Academy of Pediatrics (AAP) 2011 safe sleep recommendations, (b) describe tone and framing of the messages (e.g., use of fear appeals), (c) describe targeting/tailoring of messages to priority populations, and (d) ascertain whether the campaigns have been evaluated for reach and/or effectiveness. Methods included computer-assisted analyses of campaign materials and key informant interviews. All campaigns included "ABC" (Alone, Back, Crib) messaging; many ignored other AAP recommendations such as breastfeeding, room-sharing, immunizations, and avoiding smoke exposure. Campaigns frequently targeted priority populations such as African Americans. Fear appeals were used in three quarters of the campaigns, and 60% of the fear-based campaigns used guilt/blame messaging. We did not find published evaluation data for any of the campaigns. More attention is needed in public education campaigns to the full range of AAP recommendations, and evaluations are needed to determine the impact of these interventions on knowledge, behavior, and health outcomes.

Health risk assessments with tailored feedback plus health education have been shown to be effective for promoting health behavior change. However, there is limited evidence to guide the development and delivery of online automated tailored feedback. The goal of this study was to optimize tailored feedback messages for an online health risk assessment to promote enhanced user engagement, self-efficacy, and behavioral intentions for engaging in healthy behaviors. We examined the effects of three theory-based message factors used in developing tailored feedback messages on levels of engagement, self-efficacy, and behavioral intentions. We conducted a randomized factorial experiment to test three different components of tailored feedback messages: tailored expectancy priming, autonomy support, and use of an exemplar. Individuals (N=1945) were recruited via Amazon Mechanical Turk and randomly assigned to one of eight different experimental conditions within one of four behavioral assessment and feedback modules (tobacco use, physical activity [PA], eating habits, and weight). Participants reported self-efficacy and behavioral intentions pre- and postcompletion of an online health behavior assessment with tailored feedback. Engagement and message perceptions were assessed at follow-up. For the tobacco module, there was a significant main effect of the exemplar factor (P=.04); participants who received exemplar messages (mean 3.31, SE 0.060) rated their self-efficacy to quit tobacco higher than those who did not receive exemplar messages (mean 3.14, SE 0.057). There was a three-way interaction between the effect of message conditions on self-efficacy to quit tobacco (P=.02), such that messages with tailored priming and an exemplar had the greatest impact on self-efficacy to quit tobacco. Across PA, eating habits, and weight modules, there was a three-way interaction among conditions on self-efficacy (P=.048). The highest self-efficacy scores were reported among those who
Public participation has become an important element of governance in many Western European countries. However, among scholars and practitioners there is a recognition that participatory governance processes tend to produce systematic exclusions. Knowledge about 'who' participates and 'how......' they participate can enhance our understanding of participatory processes.

This preliminary study examined the effect of gain versus loss-framed messaging as well as culturally targeted personal prevention messaging on African Americans' receptivity to colorectal cancer (CRC) screening. This research also examined mechanistic functions of perceived racism in response to message framing. Community samples of African Americans (N = 132) and White Americans (N = 50) who were non-compliant with recommended CRC screening completed an online education module about CRC, and were either exposed to a gain-framed or loss-framed message about CRC screening. Half of African Americans were exposed to an additional and culturally targeted self-control message about personal prevention of CRC. Theory of planned behavior measures of attitudes, normative beliefs, perceived behavioural control, and intentions to obtain a CRC screen served as primary outcomes. The effect of messaging on perceived racism was also measured as an outcome. Consistent with prior research, White Americans were more receptive to CRC screening when exposed to a loss-framed message. However, African Americans were more receptive when exposed to a gain-framed message. The contrary effect of loss-framed messaging on receptivity to screening among African Americans was mediated by an increase in perceived racism. However, including an additional and culturally targeted prevention message mitigated the adverse effect of a loss-framed message. This study identifies an important potential cultural difference in the effect of message framing on illness screening among African Americans, while also suggesting a culturally relevant linking mechanism. This study also suggests the potential for simultaneously presented and culturally targeted messaging to alter the effects of gain and loss-framed messaging on African Americans. What is already known on this subject? African Americans are at an increased risk of both developing and dying from colorectal cancer (CRC). These disparities can be

This article was based on a speech presented at a Plenary Session of the 1996 Annual Meeting of the American Society of Tropical Medicine and Hygiene. The address describes the nature of social marketing with examples and some lessons learned in developing countries. The earliest social marketers were Moses with the Ten Commandments of God and Indian religious authorities with fertility motifs inscribed on temple walls. Modern marketers of beer and snack food preempted the ancients and made social marketing more ingenious. The strategy shifted to supplying a product to satisfy a consumer want. Messages became a two-way process that minimized feedback shock. Focus groups were used to probe consumers' thoughts. Research must probe the total environment of the "problem." In Brazil, breast feeding promotions revealed that the perceived problem may not be the real problem, and there was no single magic solution. Most tropical disease prevention approaches do not rely on multistage strategies. The oral rehydration therapy (ORT) strategy became a world-wide model when strategists realized that the formula had to be easy to remember, diarrhea had to be recognized as a disease, and the function of ORT had to be clearly defined. The Bangladesh Social Marketing Campaign was successful in getting men to discuss family planning with their wives and establishing the family planning worker as a heroine. Effective messages must uncover points of resistance to the message. Public health advances in the 19th century were due to social policy to improve water supply, sanitation, and nutrition. The iodization of salt in Ecuador was possible with political will, public awareness, redirection of perception, and motivation of demand. Social marketing resources exist in all countries nowadays. Only medical and scientific professionals can promote concern about tropical diseases and raise the prevention priority on the public agenda.

In order to reduce harms from alcohol, evidence-based policies are to be introduced and sustained. To facilitate the dissemination of policies that reduce alcohol-related harms by documenting, comparing, and sharing information on effective alcohol polices related to restrictions on alcohol marketing and alcohol warning messaging in 10 Canadian provinces. Team members developed measurable indicators to assess policies on (a) restrictions on alcohol marketing, and (b) alcohol warning messaging. Indicators were peer-reviewed by three alcohol policy experts, refined, and data were collected, submitted for validation by provincial experts, and scored independently by two team members. The national average score was 52% for restrictions on marketing policies and 18% for alcohol warning message policies. Most provinces had marketing regulations that went beyond the federal guidelines with penalties for violating marketing regulations. The provincial liquor boards' web pages focused on product promotion, and there were few restrictions on sponsorship activities. No province has implemented alcohol warning labels, and Ontario was the sole province to have legislated warning signs at all points-of-sale. Most provinces provided a variety of warning signs to be displayed voluntarily at points-of-sale; however, the quality of messages varied. Conclusions/Importance: There is extensive alcohol marketing with comparatively few messages focused on the potential harms associated with alcohol. It is recommended that governments collaborate with multiple stakeholders to maximize the preventive impact of restrictions on alcohol marketing and advertising, and a broader implementation of alcohol warning messages.

Mobile Health (mHealth) has emerged as a promising direction for delivery of healthcare services via mobile communication devices such as cell phones. Examples include texting-based interventions for chronic disease monitoring, diabetes management, control of hypertension, smoking cessation, monitoring medication adherence, appointment keeping and medical test result delivery; as well as improving patient-provider communication, health information communication, data collection and access to health records. While existing messaging systems very well support bulk messaging and some polling applications, they are not designed for data collection and processing of health research oriented studies. For that reason known studies based on text-messaging campaigns have been constrained in participant numbers. In order to empower healthcare promotion and education research, this paper presents a system dedicated for healthcare research. It is designed for convenient communication with various study groups, feedback collection and automated processing.

Distressing imagery is often used to improve the persuasiveness of mass-reach health promotion messages, but its effectiveness may be limited because audiences avoid attending to content. Prior self-affirmation or self-efficacy inductions have been shown to reduce avoidance and improve audience responsiveness to distressing messages, but these are difficult to introduce into a mass-reach context. Reasoning that a behavioural recommendation may have a similar effect, we reversed the traditional threat-behavioural recommendation health promotion message sequence. 2 × 2 experimental design: Factor 1, high- and low-distress images; Factor 2, threat-recommendation and recommendation-threat sequences. Ninety-one students were exposed to an identical text message accompanied by high- or low-distress imagery presented in threat-recommendation and recommendation-threat sequences. For the high-distress message, greater persuasion was observed for the recommendation-threat than the threat-recommendation sequence. This was partially mediated by participants' greater self-exposure to the threat component of the message, which we attribute to the effect of sequence in reducing attentional avoidance. For the low-distress message, greater persuasion was observed for the threat-recommendation sequence, which was not mediated by reading time allocated to the threat. Tailoring message sequence to suit the degree of distress that message developers wish to induce provides a tool that could improve persuasive messages. These findings provide a first step in this process and discuss further steps needed to consolidate and expand these findings. Statement of contribution What is already known on this subject? Health promotion messages accompanied by distressing imagery might, under some circumstances, persuade individuals to engage in healthier behaviour. Audiences can respond defensively to distressing imagery, but may be less inclined to do so when an easily followed behavioural

It is demonstrated how to generate time series with tailored nonlinearities by inducing well-defined constraints on the Fourier phases. Correlations between the phase information of adjacent phases and (static and dynamic) measures of nonlinearities are established and their origin is explained. By applying a set of simple constraints on the phases of an originally linear and uncorrelated Gaussian time series, the observed scaling behavior of the intensity distribution of empirical time series can be reproduced. The power law character of the intensity distributions being typical for, e.g., turbulence and financial data can thus be explained in terms of phase correlations.

As legalization of nonmedical retail marijuana increases, states are implementing public health campaigns designed to prevent increases in youth marijuana use. This study investigated which types of marijuana-related messages were rated most highly by parents and their teens and whether these preferences differed by age and marijuana use. Nine marijuana-focused messages were developed as potential radio, newspaper, or television announcements. The messages fell into four categories: information about the law, general advice/conversation starters, consequences of marijuana use/positive alternatives, and information on potential harmful effects of teen marijuana use. The messages were presented through an online survey to 282 parent (84% female) and 283 teen (54% female) participants in an ongoing study in Washington State. Both parents and youth rated messages containing information about the law higher than other types of messages. Messages about potential harms of marijuana use were rated lower than other messages by both generations. Parents who had used marijuana within the past year (n = 80) rated consequence/positive alternative messages lower than parent nonusers (n = 199). Youth marijuana users (n = 77) and nonusers (n = 202) both rated messages containing information about the law higher than other types of messages. Youth users and nonusers were less likely than parents to believe messages on the harmful effects of marijuana. The high ratings for messages based on information about the marijuana law highlight the need for informational health campaigns to be established as a first step in the marijuana legalization process.

Schema correspondence theory (Brannon and Brock, 1994) was applied to the topic of selective exposure to health information. The following question was asked: When do people prefer to expose themselves to health-relevant information tailored to match their own needs and values (i.e., recipient self-schema matching) versus the values and goals that the healthy behavior brings to mind (i.e., behavior schema matching)? In general, recipient self-schema matched messages tended to be preferred over behavior schema matched messages. However, this tendency was attenuated to the extent that the behavior had a very well defined (prototypical) schema.
Direct-to-consumer (DTC) advertising saturates popular health magazines, communicating persuasive messages to readers that may influence attitudes and behaviors. This research used a two-prong approach to investigate the visual elements used in DTC advertising and their influence on consumers' understanding of a disease and its treatment options. An analysis was conducted of DTC advertisements (N = 62) from a population sample of Arthritis Today magazine, 2000-2010. Three panels of people with arthritis were used to validate the findings and discuss implications for health literacy. Pharmaceutical companies have an opportunity to communicate tailored messages to readers of niche publications and improve disease management.

Adolescents participating in weight loss programs experience difficulty adhering to behavior change recommendations. Communications technology provides a low cost means to increase the frequency of contact with adolescents which can improve their engagement and also lead to behavior change. Within a larger project on the development of tailored text messages for adolescents enrolled in an existing multidisciplinary weight management program, this study explored participants' perspectives about message content. A library of messages was developed focused on topics central to weight management. Four focus groups were conducted with a total of 24 participants from the weight management program to gage their reactions to the messages. Detailed notes from the focus groups were analyzed to assess the acceptability of individual messages and to identify overriding themes. Results indicate that participants were very enthusiastic about receiving text messages. They preferred messages that provided recipe ideas, included successful weight loss strategies used by peers, and requested feedback regarding their progress. They preferred positive, encouraging, and direct messages. They were unanimous that messages should include encouraging symbols (e.g., exclamation points and "smiley faces") as often as possible. They emphasized that any mention of unhealthy foods or behaviors would trigger them to eat those foods or engage in those behaviors. Text messaging acronyms (e.g., LOL) were considered too informal for messages from healthcare providers. This study suggests that including text messages in obesity interventions is acceptable to obese adolescents as a means of supporting their weight loss efforts, and it highlights the need for such messages to be carefully constructed.

The World Health Organization recommends that all countries develop a cancer control program. Qatar is the first country in the Gulf Cooperation Council to develop such a plan, with its National Cancer Strategy 2011-2016. Three years into implementation, meaningful progress has been made, particularly in reducing patient waiting times, creating a multidisciplinary approach to cancer treatment, and fostering international research collaboration. Challenges include attracting sufficient numbers of trained health care workers, reaching a diverse population with messages tailored to their needs, and emphasizing cancer prevention and early detection in addition to research and treatment. Qatar's example shows that best practices developed in North America, Western Europe, and Australasia can be assimilated in a very different demographic and cultural context when such approaches are tailored to local characteristics and circumstances.

In 2007, the State of Hawaii, Healthy Hawaii Initiative conducted a statewide social-marketing campaign promoting increased physical activity and nutrition. The campaign included substantial formative research to develop messages tailored for Hawaii's multiethnic Asian and Pacific Islander populations. The authors conducted a statewide random digital dialing telephone survey to assess the campaign's comparative reach among individuals with different ethnicities and different levels of education and income. This analysis suggests that the intervention was successful in reaching its target ethnic audiences. However, a knowledge gap related to the campaign appeared among individuals with incomes less than 130% of the poverty level and those with less than a high school education. These results varied significantly by message and the communication channel used. Recall of supermarket-based messages was significantly higher among individuals below 130% of the poverty level and those between 18 and 35 years of age, 2 groups that showed consistently lower recall of messages in other channels. Results suggest that cultural tailoring for ethnic audiences, although important, is insufficient for reaching low-income populations, and that broad-based social marketing campaigns should consider addressing socioeconomic status-related channel preferences in formative research and campaign design.

Excessive alcohol consumption is a persistent problem in Northern European cultures. Across a 2-week period, we tested the effect of varying message frames, message types, and response measures, in reducing alcohol consumption. Three hundred and twenty-three respondents were allocated to a 2 (message frame: gain vs. loss) × 2 (message type: health vs. social) × 2 (response type: engaging vs. refraining) mixed design. Binge drinking and units consumed were measured at Time 1 and Time 2 (2 weeks later). Participants read (following Time 1) a gain- or loss-framed message on binging emphasizing either social or health consequences and answered engaging in or refraining from drinking attitude measures. No main effects were identified. The key finding was that gain-framed messages, when used in conjunction with engage response measures (an incongruous pairing), were highly effective in reducing alcohol consumption 2 weeks later compared with the other message frame/response measure combinations. We suggest that for prevention behaviours, gain-framed messages, when paired with engage response measures, initiate an inconsistency resolution process. Together, our findings emphasize the importance of message frame and response type when seeking to reduce alcohol consumption using persuasive health messages. © 2014 The British Psychological Society.
Tailor welded blanks had been widely used in the automobile industry. A tailor welded blank consists of several flat sheets that were laser welded together before stamping. A combination of different materials, thickness, and coatings could be welded together to form a blank for stamping car body panels. As for the material for automobile industry, this technology was one of the development trend for automobile industry because of its weight reduction, safety improvement and economical use of materials. In this paper, the characters and production of tailor welded blanks in the market were discussed in detail. There had two major methods to produce tailor welded blanks. Laser welding would replace mesh seam welding for the production of tailor welded blanks in the future. The requirements on the edge preparation of unwelded blanks for tailor welded blanks were higher than the other steel processing technology. In order to produce the laser welded blank, there had the other process before the laser welding in the factory. In the world, there had three kinds of patterns for the large volume production of tailor welded blanks. In China, steel factory played the important role in the promotion of the application of tailor welded blanks. The competition for the supply of tailor welded blanks to the automobile industry would become fierce in the near future. As a result, the demand for the quality control on the production of tailor welded blanks would be the first priority concern for the factory.

As scholars involved with the Search for Extraterrestrial Intelligence (SETI) have contemplated how we might portray humankind in any messages sent to civilizations beyond Earth, one of the challenges they face is adequately representing the diversity of human cultures. For example, in a 2003 workshop in Paris sponsored by the SETI Institute, the International Academy of Astronautics (IAA) SETI Permanent Study Group, the International Society for the Arts, Sciences and Technology (ISAST), and the John Templeton Foundation, a varied group of artists, scientists, and scholars from the humanities considered how to encode notions of altruism in interstellar messages . Though the group represented 10 countries, most were from Europe and North America, leading to the group's recommendation that subsequent discussions on the topic should include more globally representative perspectives. As a result, the IAA Study Group on Interstellar Message Construction and the SETI Institute sponsored a follow-up workshop in Santa Fe, New Mexico, USA in February 2005. The Santa Fe workshop brought together scholars from a range of disciplines including anthropology, archaeology, chemistry, communication science, philosophy, and psychology. Participants included scholars familiar with interstellar message design as well as specialists in cross-cultural research who had participated in the Symposium on Altruism in Cross-cultural Perspective, held just prior to the workshop during the annual conference of the Society for Cross-cultural Research . The workshop included discussion of how cultural understandings of altruism can complement and critique the more biologically based models of altruism proposed for interstellar messages at the 2003 Paris workshop. This paper, written by the chair of both the Paris and Santa Fe workshops, will explore the challenges of communicating concepts of altruism that draw on both biological and cultural models.

Purpose To test the long-term effects of a mass media intervention that used culturally and developmentally appropriate messages to enhance HIV-preventive beliefs and behavior of high-risk African-American adolescents. Methods Television and radio messages were delivered over three years in two cities (Syracuse, NY and Macon, GA) that were randomly selected within each of two regionally matched city pairs with the other cities (Providence, RI and Columbia, SC) serving as controls. African American adolescents ages 14 to 17 (N = 1710), recruited in the four cities over a 16-month period, completed audio computer-assisted self-interviews at recruitment and again at 3, 6, 12 and 18-months post-recruitment to assess the long-term effects of the media program. To identify the unique effects of the media intervention, youth who completed at least one follow-up and who did not test positive for any of three sexually transmitted infections at recruitment or at 6 and 12-month follow-up were retained for analysis (N=1346). Results The media intervention reached virtually all of the adolescents in the trial and produced a range of effects including improved normative condom-use negotiation expectancies and increased sex refusal self-efficacy. Most importantly, older adolescents (ages 16-17) exposed to the media program exhibited a less risky age trajectory of unprotected sex than those in the non-media cities. Conclusions Culturally tailored mass media messages delivered consistently over time have the potential to reach a large audience of high-risk adolescents, to support changes in HIV-preventive beliefs, and to reduce HIV-associated risk behaviors among older youth.

To examine how video messages from a recent media campaign affected public attitudes about obesity prevention and weight-based stigma toward obese children. A survey-embedded experiment in May-June 2012 with nationally representative sample (N = 1,677) was conducted. Participants were randomized to view one of three messages of children recounting struggles with obesity, or to a control group. It was examined whether message exposure affected attitudes about: (1) the seriousness of childhood obesity and its consequences; (2) responsibility for addressing obesity; (3) support for prevention policies, and (4) stigma toward obese children. Participants viewing the messages attributed greater responsibility for addressing childhood obesity to the food and beverage industry, schools, and the government, compared to those in the control group. Overweight and female respondents viewing the messages reported lower weight-based stigma compared with overweight and female respondents in the control group, but messages had no effect on healthy weight and male respondents. Messages did not affect attitudes about the seriousness of childhood obesity, its consequences, or support for obesity prevention policies. It will be critical to assess on an ongoing basis how communication campaigns addressing childhood obesity shape public attitudes about obesity prevention. Copyright © 2013 The Obesity Society.

Popularity of social marketing messages indicates the effectiveness of the corresponding marketing strategies. This research aims to discover the characteristics of social marketing messages that contribute to different level of popularity. Using messages posted by a sample of restaurants on Facebook as a case study, we measured the message popularity by the number of "likes" voted by fans, and examined the relationship between the message popularity and two properties of the messages: (1) content, and (2) media type. Combining a number of text mining and statistics methods, we have discovered some interesting patterns correlated to "more popular" and "less popular" social marketing messages. This work lays foundation for building computational models to predict the popularity of social marketing messages in the future.

Fruit and vegetable consumption (FVC) is associated with a reduced risk of diabetes, obesity, cancer, and cardiovascular disease. Only one third of children aged 4-8years consume the recommended 5 servings a day. Studies involving school-aged children (6-11 years) demonstrate that positive outcome expectancies can mediate FVC. There is a lack of similar studies involving preschool-aged (vegetables, messages they recall hearing related to FVC, and how they perceive these messages. Children (N = 192) were individually interviewed with a play-based picture card game followed by a mealtime environment reenactment open-ended interview. Fruit and vegetable messages were operationalized using Social Cognitive Theory (SCT). Descriptive statistics and associations are reported. Each child recalled an average of 2.27 messages associated with FVC. Positive outcome expectancies, negative outcome expectancies, and prompts were most frequently recalled. Statistically significant differences in knowledge, preference, and messages were observed based on income. Children as young as age 4 years understand positive outcome expectancies. Experimental trials are warranted to determine if tailored expectancy messages mediate FVC among preschool children. © 2015, American School Health Association.

Objectives We assessed public views about the acceptability of and need for sexually transmitted disease (STD) and sexual health-related educational messaging in local campaigns. Methods A 28-item state-added module was included in the 2008 New York Behavioral Risk Factor Surveillance System survey (n=3,751). Respondents rated acceptability of venues/dissemination channels and messaging and agreement with attitudinal/need statements. Additional data were analyzed from a separate state survey with individual county samples (n=36,257). We conducted univariate, bivariate, and multivariable modeling analyses. Results Each venue was acceptable to more than three-quarters of respondents (range: 79% for billboards to 95% for teaching STD prevention in high school). All message areas were acceptable to at least 85% of respondents (acceptability rating range: 85% to 97%). More than 70% agreed that there is a need for more open discussion about STDs. Bivariate analyses identified areas where messaging tailored to specific subgroups may be helpful (e.g., 26% of white people, 44% of African Americans, and 45% of Hispanic people agreed with the statement, “I need ideas about how to talk to my partner about protection from STDs”). Little geographic variation was seen. Results of multivariable modeling on opposition showed limited interaction effects. Conclusion These data provide key information about current community norms and reflect the public's approval for hearing and seeing more about sexual health and STDs in a range of public forums.

Research on regulatory focus has established a regulatory matching effect: The persuasiveness of a message is enhanced when regulatory orientations of message and perceiver match (i.e., both are promotion or both are prevention). We report evidence that varying the hedonic outcome reverses this effect. We manipulated hedonic outcome by explicitly stating pleasurable versus painful outcomes as part of the message frame as well as by priming perceivers to focus on either pleasurable or painful outcomes. When both message and perceiver were focused on pleasurable outcomes, we replicated the regulatory matching effect. However, the matching effect reversed when the hedonic outcome of the message was opposed to that of the perceiver (i.e., one was pleasurable and the other painful). Under these conditions, messages that mismatched the perceivers' regulatory orientation were more persuasive (i.e., promotion message for a prevention oriented perceiver or vice versa). We also examined the persuasion effects when both message and perceiver were focused on painful outcomes and found that the regulatory matching effect re-emerged. The reversal of the regulatory matching effect by hedonic outcome strongly suggests that hedonic motives (approach of pleasure vs. avoidance of pain) and regulatory focus motives are distinct constructs. This is important because contrary to theoretical statements these constructs have often been confounded.

Depression is highly prevalent among college students. Although treatment is often available on university campuses, many stigma-based barriers prevent students from seeking help. Communication strategies, such as the use of metaphors, are needed to reduce barriers. Specially, the use of visual metaphors, as a strategic message design tactic, may be an effective communication strategy to increase message appeal and engagement. Using a 2-phase approach, this study first identified common metaphors students use to conceptualize mental illness. Messages incorporating conceptual and visual metaphors were then designed and tested to determine their potential in reducing stigma. Participants (n = 256) were randomly assigned to 1 of 4 conditions in a between-subjects experiment: messages with visual and textual metaphors, messages with straightforward visuals and textual metaphors, text-based metaphor messages, or a control group. Overall, metaphorical messages are appealing, the use of visual metaphors leads to greater message engagement, and messages based on conceptual metaphors have the potential to reduce stigma. The use of conceptual and visual metaphors in campaign design is an effective strategy to communicate about a complex health topic, such as mental illness, and should be considered for use in campaigns to reduce barriers for help-seeking behavior.

Transgender women in the U.S. have an alarmingly high incidence rate of HIV infection; condomless anal and vaginal sex is the primary risk behavior driving transmission. Young transgender women are the subpopulation at the highest risk for HIV. Despite this, there are no published randomized controlled efficacy trials testing interventions to reduce sexual risk for HIV among this group. This paper describes the design of a group-based intervention trial to reduce sexual risk for HIV acquisition and transmission in young transgender women. This study, funded by the National Institutes of Health, is a randomized controlled trial of a culturally-specific, empowerment-based, and group-delivered six-session HIV prevention intervention, Project LifeSkills, among sexually active young transgender women, ages 16-29 years in Boston and Chicago. Participants are randomized (2:2:1) to either the LifeSkills intervention, standard of care only, or a diet and nutrition time- and attention-matched control. At enrollment, all participants receive standardized HIV pre- and post-test counseling and screening for HIV and urogenital gonorrhea and chlamydia infections. The primary outcome is difference in the rate of change in the number of self-reported condomless anal or vaginal sex acts during the prior 4-months, assessed at baseline, 4-, 8-, and 12-month follow-up visits. Behavioral interventions to reduce sexual risk for HIV acquisition and transmission are sorely needed for young transgender women. This study will provide evidence to determine feasibility and efficacy in one of the first rigorously designed trials for this population.

To describe the process and feasibility of our randomised, controlled intervention study (NuAD trial) that positively affected the nutrition and quality of life, and prevented falls of home-dwelling persons with Alzheimer disease (AD). This qualitative study comprised 40 persons with AD and spousal caregivers of our trial. Our intervention during one year involved tailored nutritional guidance for these couples. The nutritionist's field notes (about 100 pages) and the participant feedback questionnaires (N = 28) served to analyse the feasibility of intervention, factors promoting the application of intervention and challenges hindering it. Thematic content analysis served to analyse our data with the grounded theory approach. We identified several positive elements promoting better nutrition: positive attitudes on nutrition to participants including a participant-centred approach, positive feedback, findings of food diaries and practical suggestions. Home visits by the nutritionist were convenient and participants felt that someone cares. Group meetings which included protein-rich snacks strengthened the nutritional message by enabling discussions and socialising. The oral nutritional supplements (ONS) helped participants to regain their energy and to motivate them to exercise and make changes in their diets. Obstacles to making changes in diets included participants' false ideas about nutrition, especially with regard to weight gain. Health problems and functional limitations hampered food management, and some families had inveterate eating habits. The positive feedback from participants indicated the feasibility of our tailored nutritional guidance. Assessment-based, tailored nutritional guidance implemented with a personal and positive approach may inspire and empower AD families to make positive changes in their diets, leading them to improved nutrition and quality of life.

Risk Communication Study Team (hereafter called RC team) has designed messages for risk communication based on the analysis of the local residents' opinions which were expressed in several questionnaire surveys. The messages are described in a side format (Power Point format) every single content. This report provides basic guidelines for making messages that are used for risk communication, and does not include concrete messages which RC team designed. The RC team has already published the report entitled 'Information materials for risk communication' (JNC TN8450 2003-008) separately, and it gives the concrete messages. This report shows general cautions and checklists in designing messages, comments on the messages from outside risk communication experts, and opinions from local residents. (author)

Persuading people to undertake actions to prevent skin cancer is an important public health challenge. A number of studies have compared the effectiveness of gain-framed and loss-framed appeals in this domain, often expecting gain-framed appeals to be more persuasive. A meta-analytic review (k = 33, N = 4,168), however, finds no significant difference in the persuasiveness of gain- and loss-framed appeals for encouraging skin cancer prevention. This conclusion is unaffected by differences in the specific protective action advocated or by differences in the kind of outcomes invoked. But the results offer an intimation that men might be more susceptible to framing variations in this domain—with loss-framed appeals potentially having a persuasive advantage. PMID:22829794

Although routine dental checkups are important for both oral and overall health, several factors influence young adults' use or nonuse of dental services. The two studies included in this report tested the theory of reasoned action (TRA), the theory of planned behavior (TPB), and an expanded TPB model in predicting young adults' routine dental checkups. Additionally, the study tested the perceived message effectiveness of TPB-based messages. Results support the use of an expanded TPB model (particularly adding satisfaction with the dentist and environmental constraints to the traditional model) for an understanding of routine dental checkup intention and behavior, and, most notably, provide support for the use of subjective norm-based messages to prompt dental checkups. This study lays the groundwork for a health communication campaign encouraging routine dental checkups among young adults. The use of targeting and tailoring to design effective oral health media campaign messages is discussed.

The tsunami disaster affecting the Indian Ocean region on Christmas 2004 demonstrated very clearly the shortcomings in tsunami detection, public warning processes as well as intergovernmental warning message exchange in the Indian Ocean region. In that regard, early warning systems require that the dissemination of early warning messages has to be executed in way that ensures that the message delivery is timely; the message content is understandable, usable and accurate. To that end, diverse and multiple dissemination channels must be used to increase the chance of the messages reaching all affected persons in a hazard scenario. In addition to this, usage of internationally accepted standards for the warning dissemination such as the Common Alerting Protocol (CAP) and Emergency Data Exchange Language (EDXL) Distribution Element specified by the Organization for the Advancement of Structured Information Standards (OASIS) increase the interoperability among different warning systems enabling thus the concept of system-of-systems proposed by GEOSS. The project Distant Early Warning System (DEWS), co-funded by the European Commission under the 6th Framework Programme, aims at strengthening the early warning capacities by building an innovative generation of interoperable tsunami early warning systems based on the above mentioned concepts following a Service-oriented Architecture (SOA) approach. The project focuses on the downstream part of the hazard information processing where customized, user-tailored warning messages and alerts flow from the warning centre to the responsible authorities and/or the public with their different needs and responsibilities. The information logistics services within DEWS generate tailored EDXL-DE/CAP warning messages for each user that must receive the message according to their preferences, e.g., settings for language, interested areas, dissemination channels, etc.. However, the significant difference in the implementation and

To explore men's fall experiences through the lens of masculine identities so as to assist health professionals better engage men in fall prevention programs. Twenty-five men, aged 70-93 years who had experienced a recent fall, participated in a qualitative semi-structured interview. Men's willingness to engage in fall prevention programs taking account of individual contexts and expressions of masculinity, were conceptualised using constant comparative methods. Men's willingness to engage in fall prevention programs was related to their perceptions of the preventability of falls; personal relevance of falls; and age, health, and capability as well as problem-solving styles to prevent falls. Fall prevention advice was rarely given when men accessed the health system at the time of a fall. Contrary to dominant expectations about masculine identity, many men acknowledged fall vulnerability indicating they would attend or consider attending, a fall prevention program. Health professionals can better engage men by providing consistent messages that falls can be prevented; tailoring advice, understanding men are at different stages in their awareness of fall risk and preferences for action; and by being aware of their own assumptions that can act as barriers to speaking with men about fall prevention. Implications for rehabilitation Men accessing the health system at the time of the fall, and during rehabilitation following a fall represent prime opportunities for health professionals to speak with men about preventing falls and make appropriate referrals to community programs. Tailored advice will take account of individual men's perceptions of preventability; personal relevance; perceptions of age, health and capability; and problem-solving styles.
Full Text Available University students frequently send and receive cellular phone text messages during classroominstruction. Cognitive psychology research indicates that multi-tasking is frequently associatedwith performance cost. However, university students often have considerable experience withelectronic multi-tasking and may believe that they can devote necessary attention to a classroomlecture while sending and receiving text messages. In the current study, university students whoused text messaging were randomly assigned to one of two conditions: 1. a group that sent andreceived text messages during a lecture or, 2. a group that did not engage in text messagingduring the lecture. Participants who engaged in text messaging demonstrated significantlypoorer performance on a test covering lecture content compared with the group that did notsend and receive text messages. Participants exhibiting higher levels of text messaging skill hadsignificantly lower test scores than participants who were less proficient at text messaging. It ishypothesized that in terms of retention of lecture material, more frequent task shifting by thosewith greater text messaging proficiency contributed to poorer performance. Overall, the findingsdo not support the view, held by many university students, that this form of multitasking has littleeffect on the acquisition of lecture content. Results provide empirical support for teachers andprofessors who ban text messaging in the classroom.

This study investigated the psychophysiological patterns associated with cell phone text messaging (texting). Twelve college students who were very familiar with texting were monitored with surface electromyography (SEMG) from the shoulder (upper trapezius) and thumb (abductor pollicis brevis/opponens pollicis); blood volume pulse (BVP) from the middle finger, temperature from the index finger, and skin conductance (SC) from the palm of the non-texting hand; and respiration from the thorax and abdomen. The counter-balanced procedure consisted of a 2 min pre-baseline, 1 min receiving text messages, 2 min middle baseline, 1 min sending text messages and 2 min post-baseline. The results indicated that all subjects showed significant increases in respiration rate, heart rate, SC, and shoulder and thumb SEMG as compared to baseline measures. Eighty-three percentage of the participants reported hand and neck pain during texting, and held their breath and experienced arousal when receiving text messages. Subjectively, most subjects were unaware of their physiological changes. The study suggests that frequent triggering of these physiological patterns (freezing for stability and shallow breathing) may increase muscle discomfort symptoms. Thus, participants should be trained to inhibit these responses to prevent illness and discomfort.

This study explored the use of strategic messaging by proponents of sugar-sweetened beverage (SSB) taxation to influence public opinion and shape the policy process, emphasizing the experiences in El Monte and Richmond, California, with SSB tax proposals in 2012. We conducted 18 semistructured interviews with key stakeholders about the use and perceived effectiveness of messages supporting and opposing SSB taxation, knowledge sharing among advocates, message dissemination, and lessons learned from their messaging experiences. The protax messages most frequently mentioned by respondents were reinvesting tax revenue into health-related programs and linking SSB consumption to health outcomes such as obesity and diabetes. The most frequently mentioned antitax messages addressed negative economic effects on businesses and government restriction of personal choice. Factors contributing to perceived messaging success included clearly defining "sugar-sweetened beverage" and earmarking funds for obesity prevention, incorporating cultural sensitivity into messaging, and providing education about the health effects of SSB consumption. Sugar-sweetened beverage taxation has faced significant challenges in gaining political and public support. Future campaigns can benefit from insights gained through the experiences of stakeholders involved in previous policy debates.

According to Regulatory Focus theory (RFT), outcomes in persuasive messages can be framed in four different ways, as gains, non-gains, losses or non-losses. In study 1, the persuasiveness of all four frames was compared and the presence/absence effect that was expected on the basis of the feature-positive effect was verified: Statements about present outcomes (gain, loss) were more persuasive than those about absent outcomes (non-gain, non-loss). However, this study failed to support the prediction that a gain-framed message would be more persuasive than a loss-framed message when promoting a prevention behaviour. Study 2 was designed to examine the latter finding. It was hypothesised that the threat posed by the loss-framed message in study 1 was too low to elicit a defensive reaction. Therefore, in study 2, the personal relevance of the gain and the loss framed message was manipulated. Consistent with predictions, the gain-framed message was more persuasive than the loss-framed message, but only when the message was personalised to increase self-relevance. Moreover, the effect was due to a significant drop in persuasion in the loss condition, probably caused by a defensive reaction. These data shed a new light on the findings of past framing studies.
According to a number of participants at the population conference in Ontario, sponsored by the School of Journalism of the Univesity of Western Ontario and the Canadian International Development Agency, the villages, in developing countries, have sent a message to population experts, declaring that the most effective way to motivate individuals toward reducing family size is to improve basic educational and health care services. It has been demonstrated that improvements in these areas, by providing women with educational opportunities and by reducing infant mortality, have a direct impact on fertility. Efforts should be directed toward discovering similar direct correlates. The message dismissed as irrelevant the battle raging between those who advocate that population growth must be halted before poverty can be eliminated, between the developmentalists, who believe that fundamental changes in economic and political conditions will automatically solve the population problem, and between those who declare that family planning and development must be dealt with simultaneously for either to be effective. Despite evidence demonstrating the effectiveness of the 'direct correlate' approach, most developing countries continue to accord top priority to family planning programs and neglect educational and health care services.
Full Text Available Severin Haug Swiss Research Institute for Public Health and Addiction at Zurich University, Zurich, Switzerland Background: Alcohol and tobacco use are major causes of the disease burden in most countries of the world. Mobile phone text messaging is very popular among adolescents and young adults and has the potential to deliver individualized information to large population groups at low costs. Objective: To provide a narrative review on studies testing the appropriateness and effectiveness of text messaging-based programs to reduce alcohol and tobacco use in young people. Results: Two published studies on text message-based programs for the reduction of problem drinking and two studies on programs for enhancing smoking cessation were identified. A US-American pilot experimental study tested the feasibility and initial efficacy of a text messaging-based assessment and brief intervention among young adults identified during their emergency department visit with hazardous drinking. It demonstrated the feasibility of the text messaging-based program to collect drinking data in young adults after emergency department discharge. A Swiss pre–post study tested the appropriateness and initial effectiveness of a combined, individually tailored web- and text messaging (SMS-based program to reduce problem drinking in vocational school students. It provided evidence for the appropriateness of the intervention and initial evidence for its efficacy to reduce problem drinking. One of the two studies addressing smoking cessation was a US-American pilot randomized controlled trial. Participants were recruited via online advertisements and received text messages tailored according to their quitting stage. The intervention significantly affected self-reported quitting rates at 4 weeks but not at 3 months after the quit date. Within a cluster-randomized controlled trial conducted in Switzerland, smoking students were proactively recruited within vocational

Advances in technology allowed the development of a novel smoking cessation program delivered by video messages sent to mobile phones. This social cognitive theory-based intervention (called "STUB IT") used observational learning via short video diary messages from role models going through the quitting process to teach behavioral change techniques. The objective of our study was to assess the effectiveness of a multimedia mobile phone intervention for smoking cessation. A randomized controlled trial was conducted with 6-month follow-up. Participants had to be 16 years of age or over, be current daily smokers, be ready to quit, and have a video message-capable phone. Recruitment targeted younger adults predominantly through radio and online advertising. Registration and data collection were completed online, prompted by text messages. The intervention group received an automated package of video and text messages over 6 months that was tailored to self-selected quit date, role model, and timing of messages. Extra messages were available on demand to beat cravings and address lapses. The control group also set a quit date and received a general health video message sent to their phone every 2 weeks. The target sample size was not achieved due to difficulty recruiting young adult quitters. Of the 226 randomized participants, 47% (107/226) were female and 24% (54/226) were Maori (indigenous population of New Zealand). Their mean age was 27 years (SD 8.7), and there was a high level of nicotine addiction. Continuous abstinence at 6 months was 26.4% (29/110) in the intervention group and 27.6% (32/116) in the control group (P = .8). Feedback from participants indicated that the support provided by the video role models was important and appreciated. This study was not able to demonstrate a statistically significant effect of the complex video messaging mobile phone intervention compared with simple general health video messages via mobile phone. However, there was

The Common Message Logging (CMLOG) system is an object-oriented and distributed system that not only allows applications and systems to log data (messages) of any type into a centralized database but also lets applications view incoming messages in real-time or retrieve stored data from the database according to selection rules. It consists of a concurrent Unix server that handles incoming logging or searching messages, a Motif browser that can view incoming messages in real-time or display stored data in the database, a client daemon that buffers and sends logging messages to the server, and libraries that can be used by applications to send data to or retrieve data from the database via the server. This paper presents the design and implementation of the CMLOG system meanwhile it will also address the issue of integration of CMLOG into existing control systems.

Multi-copy utility-based routing has been considered as one of the most applicable approaches to effective message delivery in Delay Tolerant Networks (DTNs). By allowing multiple message replicas launched, the ratio of message delivery or delay can be significantly reduced compared with other counterparts. Such an advantage, nonetheless, is at the expense of taking more buffer space at each node and higher complexity in message forwarding decisions. This paper investigates an efficient message scheduling and dropping policy via analytical modeling approach, aiming to achieve optimal performance in terms of message delivery delay. Extensive simulation results, based on a synthetic mobility model and real mobility traces, show that the proposed scheduling framework can achieve superb performance against its counterparts in terms of delivery delay.

Enterprise messaging is seen as an attractive mechanism to simplify and extend several portions of the Grid middleware, from low level monitoring to experiments dashboards. The production messaging service currently used by WLCG includes four tightly coupled brokers operated by EGI (running Apache ActiveMQ and designed to host the Grid operational tools such as SAM) as well as two dedicated services for ATLAS-DDM and experiments dashboards (currently also running Apache ActiveMQ). In the future, this service is expected to grow in numbers of applications supported, brokers and technologies. The WLCG Messaging Roadmap identified three areas with room for improvement (security, scalability and availability/reliability) as well as ten practical recommendations to address them. This paper describes a messaging service architecture that is in line with these recommendations as well as a software architecture based on reusable components that ease interactions with the messaging service. These two architectures will support the growth of the WLCG messaging service.

Full Text Available As the Internet begins to encapsulate more people within online communities, it is important that the social researcher have well-rounded ethnographic methodologies for observing these phenomena. This article seeks to contribute to methodology by detailing and providing insights into three specific facets of virtual ethnography that need attention: space and time, identity and authenticity, and ethics. Because the Internet is a globalized and instantaneous medium where space and time collapse, identity becomes more playful, and ethics become more tenuous; understanding these aspects is crucial to the study of online social groups. A second focus of this article is to apply these notions to the study of online message boards—a frequently used medium for online communication that is frequently overlooked by methodologists.

This study aimed to present the current information on the genetic background of dyslipidemias and provide insights into the complex pathophysiological role of several plasma lipids/lipoproteins in the pathogenesis of atherosclerotic cardiovascular disease. Furthermore, we aim to summarize established therapies and describe the scientific rationale for the development of novel therapeutic strategies. Evidence from genetic studies suggests that besides lowering low-density lipoprotein cholesterol, pharmacological reduction of triglyceride-rich lipoproteins, or lipoprotein(a) will reduce risk for coronary heart disease. Dyslipidemia, in particular hypercholesterolemia, is a common clinical condition and represents an important determinant of atherosclerotic vascular disease. Treatment decisions are currently guided by the causative lipid phenotype and the presence of other risk factors suggesting a very high cardiovascular risk. Therefore, the identification of lipid disorders and the optimal combination of therapeutic strategies provide an outstanding opportunity for reducing the onset and burden of cardiovascular disease.

Parent-child communication about sex is an important proximal reproductive health outcome. But while campaigns to promote it such as the Parents Speak Up National Campaign (PSUNC) have been effective, little is known about how messages influence parental cognitions and behavior. This study examines which message features explain responses to sexual communication messages. We content analyzed 4 PSUNC ads to identify specific, measurable message and advertising execution features. We then develop quantitative measures of those features, including message strategies, marketing strategies, and voice and other stylistic features, and merged the resulting data into a dataset drawn from a national media tracking survey of the campaign. Finally, we conducted multivariable logistic regression models to identify relationships between message content and ad reactions/receptivity, and between ad reactions/receptivity and parents' cognitions related to sexual communication included in the campaign's conceptual model. We found that overall parents were highly receptive to the PSUNC ads. We did not find significant associations between message content and ad reactions/receptivity. However, we found that reactions/receptivity to specific PSUNC ads were associated with increased norms, self-efficacy, short- and long-term expectations about parent-child sexual communication, as theorized in the conceptual model. This study extends previous research and methods to analyze message content and reactions/receptivity. The results confirm and extend previous PSUNC campaign evaluation and provide further evidence for the conceptual model. Future research should examine additional message content features and the effects of reactions/receptivity.
Full Text Available Abstract Background Unhealthy dietary and physical activity (PA patterns are highly prevalent in most Western countries, especially among lower-educated and ethnic minority groups. Therefore, interventions to promote healthy eating and physical activity that can reach large numbers of lower-educated people are needed. When developing interventions, the ethnic diversity of the lower-educated population may be taken into account to make intervention material more appealing to the target group. This article describes the development and evaluation of two computer-tailored nutrition and physical activity interventions for lower-educated Dutch, Turkish and Moroccan women. One version is tailored to sociocognitive variables (traditional tailoring, while the other is additionally tailored to ethnic identity (EI-tailoring. Method Using intervention mapping, two evidence- and theory-based interventions were developed. In the traditional tailoring intervention, messages are tailored to health behavior, awareness of own behavior, attitude and self-efficacy. The behavior change techniques used to address these factors are: descriptive and evaluative feedback, arguments, modeling, goal setting, planning, barrier identification and advice on how to deal with barriers, stimulating resistance to social pressure, mobilization of social support (nontailored, active learning (nontailored and iterative feedback. In the EI-tailoring intervention, the material is additionally tailored to ethnic identity (EI. This means that recipients who feel strongly attached to their ethnic background receive different intervention material than recipients with a weak attachment to their background. This includes, for instance, the use of more traditional colors, role models that match with their origin and advice messages that refer to their ethnicity of origin.

Communication concepts relating to prevention and early intervention (P&E) within aesthetic medicine are poorly understood and highly underexplored. However, effective communication is a key criterion for successful outcomes. To introduce the framework for P&E communication strategies within a younger population and explore the barriers that may be encountered. A literature review on P&E communication strategies in aesthetic medicine and related topics of interest was conducted and used to construct a working framework that may be applied in clinical practice. Examination of existing literature revealed a need for a more structured communication framework for P&E encompassing up-to-date evidence-based learning and educational marketing that is tailored to individual needs and target populations. Message framing-the way in which a message is presented-is an important consideration in the dissemination of information to promote changes in health behaviour. A structured consultation is key to optimising patient engagement and ensures a tailored approach to understanding and catering to the specific needs of each patient. This is the first paper to discuss the communication concepts behind P&E within aesthetic medicine and paves the way for further research and focus in this significant field.

This current study identifies distinct parent prevention communication profiles and examines whether youth with different parental communication profiles have varying substance use trajectories over time. Eleven schools in two rural school districts in the Midwestern United States were selected, and 784 students were surveyed at three time points from the beginning of 7th grade to the end of 8th grade. A series of latent profile analyses were performed to identify discrete profiles/subgroups of substance-specific prevention communication (SSPC). The results revealed a 4-profile model of SSPC: Active-Open, Passive-Open, Active-Silent, and Passive-Silent. A growth curve model revealed different rates of lifetime substance use depending on the youth’s SSPC profile. These findings have implications for parenting interventions and tailoring messages for parents to fit specific SSPC profiles. PMID:29056872

Efforts now need to be focused on identifying ways to ensure the service can be provided equally to all, both in terms of mobile phone access and confidence in user ability. In addition, as well as creating health messages based on best practice, complimentary services such as facilitated peer discussions and other mhealth based educational resources need to be identified and incorporated into the intervention. It is the intention of SCHI to implement an interactive SMS Messaging Service, working closely with the local health centre, to make the requested health information more widely accessible and personally tailored to the residents of the Chikwawa District.

The Area Message Service (AMS) is a TCP/IP based messaging service currently in use at SLAC. A number of projects under development here at SLAC require and application level interface to the 4.3BSD UNIX socket level communications functions using TCP/IP over ethernet. AMS provides connection management, solicited message transfer, unsolicited message transfer, and asynchronous notification of pending messages. AMS is written completely in ANSI 'C' and is currently portable over three hardware/operating system/network manager platforms, VAX/VMS/Multinet, PC/MS-DOS/Pathworks, VME 68K/pSOS/pNA. The basic architecture is a client-server connection where either end of the interface may be the server. This allows for connections and data flow to be initiated from either end of the interface. Included in the paper are details concerning the connection management, the handling of the multi-platform code, and the implementation process

Epidemic processes are common out-of-equilibrium phenomena of broad interdisciplinary interest. In this thesis, we show how message-passing approach can be a helpful tool for simulating epidemic models in disordered medium like networks, and in particular for estimating the probability that a given node will become infectious at a particular time. The sort of dynamics we consider are stochastic, where randomness can arise from the stochastic events or from the randomness of network structures. As in belief propagation, variables or messages in message-passing approach are defined on the directed edges of a network. However, unlike belief propagation, where the posterior distributions are updated according to Bayes' rule, in message-passing approach we write differential equations for the messages over time. It takes correlations between neighboring nodes into account while preventing causal signals from backtracking to their immediate source, and thus avoids "echo chamber effects" where a pair of adjacent nodes each amplify the probability that the other is infectious. In our first results, we develop a message-passing approach to threshold models of behavior popular in sociology. These are models, first proposed by Granovetter, where individuals have to hear about a trend or behavior from some number of neighbors before adopting it themselves. In thermodynamic limit of large random networks, we provide an exact analytic scheme while calculating the time dependence of the probabilities and thus learning about the whole dynamics of bootstrap percolation, which is a simple model known in statistical physics for exhibiting discontinuous phase transition. As an application, we apply a similar model to financial networks, studying when bankruptcies spread due to the sudden devaluation of shared assets in overlapping portfolios. We predict that although diversification may be good for individual institutions, it can create dangerous systemic effects, and as a result

Adolescent overweight and obesity is a significant problem for health care with associated quality of life and financial concerns. This systematic review investigated text messaging as an intervention to treat or prevent obesity in adolescent populations. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was used as a guideline for the literature search and interpretation of findings. CINAHL, Medline, Cochrane Database of Systematic Reviews, PsycINFO, and SocINDEX were searched using a combination of search terms. The initial 95 articles that met the search criteria were narrowed to seven that fit the focus. Text messaging is acceptable to adolescents as an obesity treatment but data about content and timing of messages vary. The effects of text messaging on body mass index (BMI) were difficult to determine because messaging was often part of a multicomponent intervention. Text messaging as an intervention for adolescent obesity was used in various settings. There were no included studies from primary care settings. Further research is needed to determine the effect of messages on BMI and the most helpful content, timing, and frequency. This information may provide advanced practice nurses with effective, affordable tools to manage adolescent obesity in different settings. ©2015 American Association of Nurse Practitioners.

Media coverage of health issues has been criticized for creating health stigmas. The model of stigma communication (MSC, Smith, 2007) provides insights into why this is so, but it has two problems: Some of its mediators have not been supported, and it does not do a good job of predicting the transmission of stigma messages (i.e., social transmission). We present a revised model of stigma message effects in which exposure to stigma messages leads to stigma beliefs and stigmatization as a result of a person-oriented danger appraisal. In addition, message judgments-shock value and common ground-are introduced as mediators of the relationship between danger appraisal and social transmission. Participants (N = 200) were randomly assigned to read a health story written either with or without the intrinsic features of stigma messages. The revised model of stigma-message effects was supported: Reading a health news story written with (vs. without) the intrinsic features of stigma messages resulted in greater danger appraisal, which directly predicted stigma-related outcomes and indirectly predicted social transmission through message judgments. Social transmission varied by message judgment: Shocking messages were shared in ways that facilitate diffusion, but common ground messages were shared with influential others, suggesting different means by which stigma as a collective norm may emerge from interactions among community members.

Full Text Available Mario Conte has had a tailor shop in King Street, Newtown since the mid 1960s. Taking an interview with Mario as its point of departure, this article describes the persistence of a skilled worker whose practices and techniques remain the same in a world that has long changed. While inattentive to what rules might be used to decorate a shop window, Mario continues to make and sew in the way that he learnt in post-war Italy. Mario’s persistence could be described as all the skills and other elements that need to be in place to keep him working, in particular the tradition of tailoring techniques he has remained true to over the last fifty years. The hand stitching of his tailoring is like a metronome of that persistence.

We demonstrate that small quantum memories, realized via quantum error correction in multiqubit devices, can benefit substantially by choosing a quantum code that is tailored to the relevant error model of the system. For a biased noise model, with independent bit and phase flips occurring at different rates, we show that a single code greatly outperforms the well-studied Steane code across the full range of parameters of the noise model, including for unbiased noise. In fact, this tailored code performs almost optimally when compared with 10 000 randomly selected stabilizer codes of comparable experimental complexity. Tailored codes can even outperform the Steane code with realistic experimental noise, and without any increase in the experimental complexity, as we demonstrate by comparison in the observed error model in a recent seven-qubit trapped ion experiment.

The message contents will focus specifically on the evolution of altruism, drawing on recent insights in evolutionary biology, with particular emphasis on sociobiological accounts of kin selection and reciprocal altruism. This focus on altruism for message contents has several advantages. First, the subject can be translated into interstellar messages both via an existing formal interstellar language and via pictorial messages. For example, aspects of reciprocal altruism can be described through mathematical modeling, such as game theoretic approaches, which in turn can be described readily in the interstellar language Lincos. Second, concentrating on altruism as a message content may facilitate communications with extraterrestrial intelligence. Some scientists have argued that humans may be expected to communicate something about their moral status and development in an exchange with extraterrestrials. One of the most salient ways that terrestrial and extraterrestrial civilizations might be expected to evaluate one another is in terms of ethical motivations. Indeed, current search strategies assume some measure of altruism on the part of transmitting civilizations; with no guarantee of a response, the other civilization would be providing information to us with no direct payoff. Thus, concepts about altruism provide an appropriate content for interstellar messages, because the concepts themselves might be understood by extraterrestrial civilizations.

In prevailing technology trends it is apparent that the network requirements and technologies will advance in future. Therefore the need of High Performance Computing (HPC) based implementation for interconnecting clusters is comprehensible for scalability of clusters. Grid computing provides global infrastructure of interconnecting clusters consisting of dispersed computing resources over Internet. On the other hand the leading model for HPC programming is Message Passing Interface (MPI). As compared to Grid computing, MPI is better suited for solving most of the complex computational problems. MPI itself is restricted to a single cluster. It does not support message passing over the internet to use the computing resources of different clusters in an optimal way. We propose a model that provides message passing capabilities between parallel applications over the internet. The proposed model is based on Architecture for Java Universal Message Passing (A-JUMP) framework and Enterprise Service Bus (ESB) named as High Performance Computing Bus. The HPC Bus is built using ActiveMQ. HPC Bus is responsible for communication and message passing in an asynchronous manner. Asynchronous mode of communication offers an assurance for message delivery as well as a fault tolerance mechanism for message passing. The idea presented in this paper effectively utilizes wide-area intercluster networks. It also provides scheduling, dynamic resource discovery and allocation, and sub-clustering of resources for different jobs. Performance analysis and comparison study of the proposed framework with P2P-MPI are also presented in this paper.

Full Text Available Abstract Parent-child communication about sex is an important proximal reproductive health outcome. But while campaigns to promote it such as the Parents Speak Up National Campaign (PSUNC have been effective, little is known about how messages influence parental cognitions and behavior. This study examines which message features explain responses to sexual communication messages. We content analyzed 4 PSUNC ads to identify specific, measurable message and advertising execution features. We then develop quantitative measures of those features, including message strategies, marketing strategies, and voice and other stylistic features, and merged the resulting data into a dataset drawn from a national media tracking survey of the campaign. Finally, we conducted multivariable logistic regression models to identify relationships between message content and ad reactions/receptivity, and between ad reactions/receptivity and parents' cognitions related to sexual communication included in the campaign's conceptual model. We found that overall parents were highly receptive to the PSUNC ads. We did not find significant associations between message content and ad reactions/receptivity. However, we found that reactions/receptivity to specific PSUNC ads were associated with increased norms, self-efficacy, short- and long-term expectations about parent-child sexual communication, as theorized in the conceptual model. This study extends previous research and methods to analyze message content and reactions/receptivity. The results confirm and extend previous PSUNC campaign evaluation and provide further evidence for the conceptual model. Future research should examine additional message content features and the effects of reactions/receptivity.

In most computer-tailored interventions, the recipient's name is used to personalize the information. This is done to increase the process of persuasion but few empirical data exist that support this notion. An experimental laboratory study was conducted to test the effects of mentioning the participants name and to study whether it was related to the depth of processing in a 2 (personalization/standard) × 2 (weak/strong arguments) design. Over 120 student smokers were randomly assigned to one of the four experimental conditions in which they read smoking cessation messages offering (pre-tested) strong or weak arguments. Personalization was applied by mentioning the recipient's first name three times in the text. The intention to quit smoking was the dependent variable. Personalization increased persuasion when perceived personal relevance was high, but it decreased persuasion when perceived personal relevance was low. The effects on persuasion were only present in the case of strong arguments. Personalization is not always effective, and it may even lead to less persuasion. Therefore, this often used way to tailor messages must be applied with care. ©2011 The British Psychological Society.
Full Text Available When developing IoT (Internet of Things applications, context distribution is a key feature to support effective delivery of related contextual data obtained from things to all interested entities. With the advent of the IoT era, multiple billion devices can generate huge amounts of data that might be used in IoT applications. In this paper, we present a context distribution framework named SCondi utilizing the messaging service which supports MQTT—an OASIS standard IoT messaging protocol. SCondi provides the notion of context channel as a core feature to support efficient and reliable mechanism for distributing huge context information in the IoT environment. The context channel provides a pluggable filter mechanism that supports effective extraction, tailoring, authentication, and security of information.

To study the effect of various types of inoculation message treatments on resistance to persuasive and potentially deceptive health- and nutrition-related (HNR) content claims of commercial food advertisers. A three-phase experiment was conducted among 145 students from a Midwestern U.S. university. Quantitative statistical analyses were used to interpret the results. RESULTS provide clear evidence that integrating regulatory focus/fit considerations enhances the treatment effectiveness of inoculation messages. Inoculation messages that employed a preventative, outcome focus with concrete language were most effective at countering HNR advertising claims. The findings indicate that inoculation fosters resistance equally across the most common types of commercially advertised HNR product claims (e.g., absolute, general, and structure/function claims). As the drive to refine the inoculation process model continues, further testing and application of this strategy in a public health context is needed to counter ongoing efforts by commercial food advertisers to avoid government regulations against deceptive practices such as dubious health/nutrition claims. This research advances inoculation theory by providing evidence that 1) good regulatory fit strengthens the effect of refutational preemption and 2) an inoculation approach is highly effective at fostering resistance to commercial advertisers' HNR content claims. This macro approach appears far superior to education or information-based promotional health campaigns targeted solely at specific populations demonstrating rising rates of noncommunicable disease.

As optical systems are diffraction limited, it is not possible to encrypt in a single step texts containing a large amount of characters. We overcome this situation by separately encrypting several characters, along with a multiplexing procedure to obtain an encrypted keyboard. The experimental application is performed in a joint transform correlator architecture and using digital holography. We combine the different characters into a keyboard encrypted with a single phase mask together with a selection-position key that gives the right sequence to recover safe encrypted messages. The multiplexing operation we suggest is advantageous in the sense that the technique enables processing of messages that otherwise the optical system could not process in a single step. We also employ a repositioning technique to prevent both the natural background noise over recovered characters and the possible cross talk. The lack of any single key avoids the correct message recovery. Experimental results are presented to show the feasibility of our proposal, representing an actual application of the optical encrypting protocols.

Full Text Available Introduction: Osteoporosis prevention is heavily reliant on education programs, which are most effective when tailored to their intended audience. Most osteoporosis prevention education is designed for older adults, making application of these programs to younger adults difficult. Designing programs for young adults requires understanding the information-seeking practices of young adults, so that knowledge about osteoporosis can be effectively translated. Methods: Individual interviews were conducted with 60 men and women—multiethnic, Canadian young adults—to explore both the sources and types of information they search for when seeking information on nutrition or bone health. Results: The results of this study raised themes related to the sources participants use, to their interests and to ways of engaging young adults. Prevention programs should make use of traditional sources, such as peers, family members and medical professionals, as well as emerging technologies, such as social media. Choice of sources was related to the perceived authority of and trust associated with the source. Messaging should relate to young adult interests, such as fitness and food—topics on which young adults are already seeking information—rather than being embedded within specific osteoporosis awareness materials. Engaging young adults means using relatable messages that are short and encourage small changes. Small gender-based differences were found in the information-seeking interests of participants. Differences related to age were not examined. Conclusion: Creating short, action-oriented messages that are designed to encourage small changes in behaviour and are packaged with information that young adults are actively seeking is more likely to result in active engagement in prevention behaviours.

Mobile phone Short Message Service (SMS) is a tool now used by the health research community, providing the capability for instant communication between patients and health professionals. Greater understanding of how to best use SMS as a means to improve healthcare delivery and outcomes will foster innovation in research and provide an opportunity to progress as a public health community. The purposes of this systematic review are 2-fold: (1) to provide insight on the most used mobile phone SMS practices and characteristics in hypertension (HTN) outcome-focused publications and (2) to critically evaluate empirical evidence associated with SMS utilization and BP outcomes. Two independent systematic literature searches were completed. The final selected studies each then underwent data extraction and quality-rating assessment, followed by an evaluation for a meta-analysis to measure mean difference of the change in BP. A total of 6 studies meeting the inclusion criteria were included in the review. Feasibility assessment for a meta-analysis was found unfavorable because of the variation among studies. Short Message Service interventions focused on BP management were most effective in studies featuring 2-way communication and individual patient-tailored content, and guided by evidence-based HTN management practices. Short Message Service interventions for HTN management were supported through evidence provided by the studies reviewed. Short Message Service holds strong potential to bring greater innovation to HTN management and care, especially in racial/ethnic minority populations that face psychosocial and structural barriers in healthcare access and utilization.

According to the U.S. Department of Health and Human Services, health communication is "the study and use of communication strategies to inform and influence individual and community decisions that enhance health." The purpose of this article is to look at how health educators can use communication theory to create messages that are innovative, relatable, and motivating to intended audiences. Three specific communication theories are presented, along with examples of how they have been successfully used in behavior change initiatives. These three theories are offered in an effort to stimulate further investigation into how theory supports the creation of targeted, tailored, and effective communication strategies.

Not only does breast milk provides an ideal nutrient composition for the newborn, but it also contains a variety of substances that may actively influence growth and development of the infant and stimulate neonatal protection against gastrointestinal diseases. Hormones, growth factors, cytokines and even whole cells are present in breast milk and act to establish biochemical and immunological communication between mother and child. In addition, milk nutrients such as nucleotides, glutamine and lactoferrin have been shown to influence gastrointestinal development and host defense. The unique properties of milk as a mediator of biochemical messages will be presented and the clinical significance of breastfeeding in the prevention of neonatal gastrointestinal diseases will be discussed.

The increasing prevalence of diabetes and costly long-term complications associated with poor glycemic control are issues facing health services worldwide. Diabetes self-management, with the support of health care providers, is critical for successful outcomes, however, frequent clinical contact is costly. Text messages via short message service (SMS) have the advantage of instant transmission at low cost and, given the ubiquity of mobile phones, may be the ideal platform for the delivery of diabetes self-management support. A tailored text message-based diabetes support intervention called Self-Management Support for Blood Glucose (SMS4BG) was developed. The intervention incorporates prompts around diabetes education, management, and lifestyle factors (healthy eating, exercise, and stress management), as well as blood glucose monitoring reminders, and is tailored to patient preferences and clinical characteristics. To determine the usability and acceptability of SMS4BG among adults with poorly controlled diabetes. Adults (aged 17 to 69 years) with type 1 (n=12) or type 2 diabetes (n=30), a hemoglobin A1c (HbA1c) over 70 mmol/mol (8.6%), and who owned a mobile phone (n=42) were recruited to take part in a 3-month pilot study of SMS4BG. At registration, participants selected the modules they would like to receive and, where appropriate, the frequency and timing of blood glucose monitoring reminders. Patient satisfaction and perceptions of the usability of the program were obtained via semistructured phone interviews conducted at completion of the pilot study. HbA1c was obtained from patient records at baseline and completion of the pilot study. Participants received on average 109 messages during the 3-month program with 2 participants withdrawing early from the study. Follow-up interviews were completed with 93% of participants with all reporting SMS4BG to be useful and appropriate to their age and culture. Participants reported a range of perceived positive

This book presents the current research on safety message dissemination in vehicular networks, covering medium access control and relay selection for multi-hop safety message broadcast. Along with an overall overview of the architecture, characteristics, and applications of vehicular networks, the authors discuss the challenging issues in the research on performance improvement for safety applications, and provide a comprehensive review of the research literature. A cross layer broadcast protocol is included to support efficient safety message broadcast by jointly considering geographical location, physical-layer channel condition, and moving velocity of vehicles in the highway scenario. To further support multi-hop safety message broadcast in a complex road layout, the authors propose an urban multi-hop broadcast protocol that utilizes a novel forwarding node selection scheme. Additionally, a busy tone based medium access control scheme is designed to provide strict priority to safety applications in vehicle...

This investigation examined the possibility of decreasing psychological reactance to health campaigns through the use of inoculation messages. It was hypothesized that an inoculation message, which forewarned of the potential of subsequent reactance, would decrease participants' likelihood of reacting negatively to a freedom-threatening message aimed to reduce excessive alcohol consumption. Participants (N = 275) who were inoculated against potential reactance felt less threatened and experienced less reactance compared to those who did not read an inoculation message. Structural equation modeling showed that inoculation indirectly predicted lower intention to drink alcohol via the theorized mediated reactance process. This research suggests that it is possible to inoculate against self-generated cognitions that might otherwise lead toward negative health behaviors.
Full Text Available Abstract Background Tailor-made approaches enable the uptake of interventions as they are seen as a way to overcome the incompatibility of general interventions with local knowledge about the organisation of routine medical practice and the relationship between the patients and the professionals in practice. Our case is the Quattro project which is a prevention programme for cardiovascular diseases in high-risk patients in primary health care centres in deprived neighbourhoods. This programme was implemented as a pragmatic trial and foresaw the importance of local knowledge in primary health care and internal, or locally made, guidelines. The aim of this paper is to show how this prevention programme, which could be tailored to routine care, was implemented in primary care. Methods An ethnographic design was used for this study. We observed and interviewed the researchers and the practice nurses. All the research documents, observations and transcribed interviews were analysed thematically. Results Our ethnographic process evaluation showed that the opportunity of tailoring intervention procedures to routine care in a pragmatic trial setting did not result in a well-organised and well-implemented prevention programme. In fact, the lack of standard protocols hindered the implementation of the intervention. Although it was not the purpose of this trial, a guideline was developed. Despite the fact that the developed guideline functioned as a tool, it did not result in the intervention being organised accordingly. However, the guideline did make tailoring the intervention possible. It provided the professionals with the key or the instructions needed to achieve organisational change and transform the existing interprofessional relations. Conclusion As tailor-made approaches are developed to enable the uptake of interventions in routine practice, they are facilitated by the brokering of tools such as guidelines. In our study, guidelines facilitated

To improve health and reduce costs, we need to encourage patients to make better health care decisions. Since email is widely available, it may be useful for patient-directed interventions. However, we know little about how the contents of an email message can influence a health-related decision. We propose a model to understand how patients may process persuasive email messages.

The purpose of this study was to evaluate the effects of a risk factor-tailored small group education on anxiety and depressive symptoms, self-efficacy and self-care compliance in patients with first-time acute coronary syndrome (ACS) for 12-month follow-up. A quasi-experimental pretest and post-test design was used. Patients were recruited from a national university hospital from 2010 to 2011 in Korea. The group education consisted of a 60-minute long video developed using multimedia contents including voice-recorded texts, flash animation, and video clips, with nurses' dialogue. The intervention group (n = 34) participated in group education using the multimedia video in a small group of patients with similar risk factors, and received periodic telephone counseling and text messages. The control group (n = 40) received usual care and counseling upon request. Depressive symptoms decreased, and self-efficacy and self-care compliance in the areas of medication, exercise, and healthy diet practice significantly increased in patients in the intervention group, compared with those in the control group. Risk factor-tailored small group education and periodic text message were an effective strategy for decreasing depression, and increasing self-efficacy and long-term compliance with lifestyle changes in patients with first-time ACS. We suggested that risk factor-tailored small group education need to be given for first-time ACS patients for psychological support and behavioral change in clinical practice. It is also comparable to individual approach to encourage psychological and behavioral change. Copyright © 2015. Published by Elsevier B.V.

Full Text Available Gender has been an important area of research in the field of popular music studies. Numerous scholars have found that contemporary popular music functions as a locus of diverse constructions and expressions of gender. While most studies focus on content analyses of popular music, there is still a need for more research on audience’s perception of popular music’s messages. This study examined adult Malay listeners’ perceptions of gender messages in contemporary Malay songs. A total of 16 contemporary Malay songs were analysed using Fairclough’s (1992 method of text analysis. The content of the songs that conveyed messages about gender were the basis for analysis. The results showed that the messages revolve mainly around socially constructed gender roles and expectations in romantic relationships. Gender stereotypes are also used in the songs to reinforce men’s and women’s roles in romantic relationships. The results also showed that, while listeners acknowledge the songs’ messages about gender, their own perceptions of gender and what it means to be a gendered being in today’s world are neither represented nor discussed fully in the songs analysed. It is hoped the findings from this, particularly the mismatch between projected and perceived notions of gender, contribute to the field of popular Malay music studies in particular, and popular music studies in general where gender messages in popular songs and their influence on listeners’ perceptions of their own gender is concerned.
Be cautious of any unexpected messages containing web links even if they appear to come from known contacts. If you happen to click on such a link and if your permission is requested to run or install software, always decline it. Several computers at CERN have recently been broken into by attackers who have tricked users of Instant Messaging applications (e.g. MSN, Yahoo Messenger, etc.) into clicking on web links which appeared to come from known contacts. The links appeared to be photos from ‘friends’ and requested software to be installed. In practice, attacker software was installed and the messages did not come from real contacts. In the past such fake messages were mainly sent by email but now a wider range of applications are being targeted, including Instant Messaging. Cybercriminals are making growing use of fake messages to try to trick you into clicking on Web links which will help them to install malicious software on your computer. Anti-virus software cann...

When we want to sign a quantum message that we create, we can use arbitrated quantum signature schemes which are possible to sign for not only known quantum messages but also unknown quantum messages. However, since the arbitrated quantum signature schemes need the help of a trusted arbitrator in each verification of the signature, it is known that the schemes are not convenient in practical use. If we consider only known quantum messages such as the above situation, there can exist a quantum signature scheme with more efficient structure. In this paper, we present a new quantum signature scheme for known quantum messages without the help of an arbitrator. Differing from arbitrated quantum signature schemes based on the quantum one-time pad with the symmetric key, since our scheme is based on quantum public-key cryptosystems, the validity of the signature can be verified by a receiver without the help of an arbitrator. Moreover, we show that our scheme provides the functions of quantum message integrity, user authentication and non-repudiation of the origin as in digital signature schemes. (paper)

Drug use can be defined as a kind of self destruction, and it is directly linked to attitudes toward death and suicide occurring in a significant number of users of different narcotics. The aim of the authors was to look for the background of this relationship between drug and death and examine the origin, development, and motives behind heroin overdose based on an analysis of previous studies. It seems clear that pure heroin overdose increased gradually over the years. The fear of the police is the inhibitory factor of the overdose prevention and notification of emergency health care service. Signs of suicide could be the own home as the chosen location for heroin overdose and the presence of partners ("moment of death companion"). Interventions should include simple techniques such as first aid, naloxone administration, resuscitation, prevention of relapse of prisoners and social network extension involving maintenance programs.

Full Text Available Sasang constitutional medicine (SCM is a unique traditional Korean therapeutic alternative form of medicine. Based on the Yin and Yang theory and on Confucianism, humans are classified into four constitutions. These differ in terms of (i sensitivity to certain groups of herbs and medicines, (ii equilibrium among internal organic functions, (iii physical features and (iv psychological characteristics. We propose that two main axes in the physiopathology of SCM (food intake/waste discharge and consuming/storing Qi and body fluids are equivalent to the process of internal–external exchange and catabolism/anabolism in modern physiology, respectively. We then used this hypothesis to discuss the physiological and pathological principles of SCM. Constitution-based medicine is based on the theory that some medicinal herbs and remedies are only appropriate for certain constitutions and can cause adverse effects in others. The constitutional approach of SCM share the same vision as tailored medicine; an individualized therapy that can minimize the risk of adverse reaction while increasing the efficacy and an individualized self-regulation that can help prevent specific susceptible chronic disease and live healthily. There is still a long way to this goal for both SCM and tailored medicine, but we may benefit from systems approaches such as systems biology. We suggest that constitutional perspective of SCM and our hypothesis of two main processes may provide a novel insight for further studies.

Full Text Available Abstract Background Continued low adherence to physical activity recommendations illustrates the need to refine intervention strategies and increase their effectiveness. The purpose of this study was to conduct formative research related to the development of a next generation of computer-tailored interventions that use online tailored video-messages to increase physical activity. Methods Five focus groups (n = 30, aimed at males and females, aged between 35 and 60 years, that do not meet the physical activity recommendation, were conducted to allow in-depth discussion of various elements related to the development of an online video-tailored intervention. In addition, a series of questions were delivered to a random sample (n = 1261 of Australians, using CATI survey technology, to gain more information and add a quantitative assessment of feasibility related to the development of the intervention. Focus group data was transcribed, and summarised using Nvivo software. Descriptive and frequency data of the survey was obtained using SPSS 18.0. Results Nearly all of the focus group participants supported the concept of a video-tailored intervention and 35.8% of survey participants indicated that they would prefer a video-based over a text-based intervention. Participants with a slow internet-connection displayed a lower preference for video-based advice (31.9%; however less than 20% of the survey sample indicated that downloading videos would be slow. The majority of focus group and survey participants did not support the idea of using mobile phones to receive this kind of intervention and indicated that video-tailored messages should be shorter than 5 minutes. Video-delivery of content is very rich in information, which increases the challenge to appropriately tailor content to participant characteristics; focus-group outcomes indicated a large diversity in participant preferences. 52.4% of survey participants indicated that the videos should be

The need of a continuously increasing size and performance of aerospace structures has settled the composite materials as the preferred materials in aircraft structures. Apart from the clear capacity to reduce the structural weight and with it the manufacture cost and the fuel consumption while preserving proper airworthiness, the prospect of tailoring a structure using the unique directional stiffness properties of composite materials allows an aerospace engineer to optimize aircraft structures to achieve particular design objectives. This paper presents a brief review of what is known as the aeroelastic tailoring of airframes with the intent of understanding the evolution of this research topic and at the same time providing useful references for further studies.

Health-promoting messages can be framed in terms of the beneficial consequences of healthy behaviour (gain-framed messages) or the detrimental consequences of unhealthy behaviour (loss-framed messages). An influential notion holds that the perceived risk associated with the recommended behaviour determines the relative persuasiveness of gain- and loss-framed messages. This 'risk-framing hypothesis', as we call it, was derived from prospect theory, has been central to health message framing research for the last two decades, and does not cease to appeal to researchers. The present paper examines the validity of the risk-framing hypothesis. We performed six empirical studies on the interaction between perceived risk and message framing. These studies were conducted in two different countries and employed framed messages targeting skin cancer prevention and detection, physical activity, breast self-examination and vaccination behaviour. Behavioural intention served as the outcome measure. None of these studies found evidence in support of the risk-framing hypothesis. We conclude that the empirical evidence in favour of the hypothesis is weak and discuss the ramifications of this for future message framing research.

Falls are the leading cause of fatalities in construction. The Safety Pays, Falls Cost campaign aims to prevent falls in residential construction. A critical component of our social marketing approach was to involve 70 partners in reaching target audiences. We assessed partner engagement April 2012-August 2013 through: (1) baseline partnership quality interviews (eight partners); (2) pre-/post-partner "market" readiness in-depth interviews (three partners); (3) a pre-/post- (29/31 partners) online partner engagement survey; and (4) standardized metrics to measure partner activity. We found a high level of interest and engagement that increased with the addition of prompting to action through regular communication and new resources from organizers and formation of local partnerships that were able to tailor their activities to their own communities or regions. It is feasible to leverage government-labor-management partnerships that enjoy trust among target audiences to widely disseminate campaign materials and messages. © 2015 Wiley Periodicals, Inc.

To test the effectiveness of messages designed to reduce vaccine misperceptions and increase vaccination rates for measles-mumps-rubella (MMR). A Web-based nationally representative 2-wave survey experiment was conducted with 1759 parents age 18 years and older residing in the United States who have children in their household age 17 years or younger (conducted June-July 2011). Parents were randomly assigned to receive 1 of 4 interventions: (1) information explaining the lack of evidence that MMR causes autism from the Centers for Disease Control and Prevention; (2) textual information about the dangers of the diseases prevented by MMR from the Vaccine Information Statement; (3) images of children who have diseases prevented by the MMR vaccine; (4) a dramatic narrative about an infant who almost died of measles from a Centers for Disease Control and Prevention fact sheet; or to a control group. None of the interventions increased parental intent to vaccinate a future child. Refuting claims of an MMR/autism link successfully reduced misperceptions that vaccines cause autism but nonetheless decreased intent to vaccinate among parents who had the least favorable vaccine attitudes. In addition, images of sick children increased expressed belief in a vaccine/autism link and a dramatic narrative about an infant in danger increased self-reported belief in serious vaccine side effects. Current public health communications about vaccines may not be effective. For some parents, they may actually increase misperceptions or reduce vaccination intention. Attempts to increase concerns about communicable diseases or correct false claims about vaccines may be especially likely to be counterproductive. More study of pro-vaccine messaging is needed.

At any one moment in time, researchers affiliated with the Institut Pierre Simon Laplace (IPSL) climate modeling group, are running hundreds of global climate simulations. These simulations execute upon a heterogeneous set of High Performance Computing (HPC) environments spread throughout France. The IPSL's simulation execution runtime is called libIGCM (library for IPSL Global Climate Modeling group). libIGCM has recently been enhanced so as to support realtime operational use cases. Such use cases include simulation monitoring, data publication, environment metrics collection, automated simulation control … etc. At the core of this enhancement is the Prodiguer messaging platform. libIGCM now emits information, in the form of messages, for remote processing at IPSL servers in Paris. The remote message processing takes several forms, for example: 1. Persisting message content to database(s); 2. Notifying an operator of changes in a simulation's execution status; 3. Launching rollback jobs upon simulation failure; 4. Dynamically updating controlled vocabularies; 5. Notifying downstream applications such as the Prodiguer web portal; We will describe how the messaging platform has been implemented from a technical perspective and demonstrate the Prodiguer web portal receiving realtime notifications.

Full Text Available With the increased usage of online technologies, there has been an escalation of Electronic Word - of –Mouth (eWOM messages related to sport products and services offered and consumed. Therefore, in this original investigation by applying eWOM to the sport industry, this study examined how the combination of the quality of the eWOM message and the provider of the eWOM message affects purchaseintentions depending on the expertise level of the consumer. This study – which involved the collection of data from 134 students at a large university situated in the Midwest of the United States – utilized repeated measures of Analysis of Variance (ANOVA with tripartite groups of expertise and experimental conditions as independent variables. Purchase intention was the dependent variables. The results indicated that the quality of the eWOM message moderated the effect of the provider of the eWOM message. The subject’s level of expertise also had a moderating role on purchase intention.

Overwhelmingly, the literature on the persuasive influence of emotions has focused on individual emotions, fear in particular, though some recent attention has been given to mixed emotions in persuasive appeals. Building on this newer wave of research, this article argues that instead of focusing on singular emotional states or collections of emotions evoked by a message, it might prove valuable to explore the flow, or evolution, of emotional experience over the course of exposure to a health message. The article offers a brief introduction to the concept of emotion, followed by a review of the state of the literature on the use of emotion in health messages. The concept of emotional flow is then introduced along with a consideration of how it has been tacitly incorporated into the study of emotional health messages. Finally, the utility of the concept of emotional flow is elaborated by articulating the ways in which it might be harnessed to facilitate the creation of more effective health messages, individually as well as across campaigns. The article concludes with an agenda for future research.

Full Text Available Abstract Background Surveys have provided evidence that tobacco use is widely prevalent amongst the youth in Pakistan. Several reviews have evaluated the effectiveness of various tobacco control programs, however, few have taken into account the perceptions of students themselves regarding these measures. The aim of this study was to determine the most effective anti-smoking messages that can be delivered to high-school students in Pakistan, based on their self-rated perceptions. It also aimed to assess the impact of pictorial/multi-media messages compared with written health warnings and to discover differences in perceptions of smokers to those of non-smokers to health warning messages. Methods This study was carried out in five major cities of Pakistan in private English-medium schools. A presentation was delivered at each school that highlighted the well-established health consequences of smoking using both written health warnings and pictorial/multi-media health messages. Following the presentation, the participants filled out a graded questionnaire form, using which they rated the risk-factors and messages that they thought were most effective in stopping or preventing them from smoking. The Friedman test was used to rank responses to each of the questions in the form. The Wilcoxon Signed Rank test used to analyze the impact of pictorial/multi-media messages over written statements. The Mann Whitney U test was used to compare responses of smokers with those of non-smokers. Results Picture of an oral cavity cancer, videos of a cancer patient using an electronic voice box and a patient on a ventilator, were perceived to be the most effective anti-smoking messages by students. Addiction, harming others through passive smoking and impact of smoking on disposable incomes were perceived to be less effective messages. Pictorial/multi-media messages were perceived to be more effective than written health warnings. Health warnings were perceived as

Sources of sexual health information exert strong influence on adolescents' sexual behavior. The current study was undertaken to understand how family serve as sexual information sources, the messages adolescents recall from family, and how family learning experiences affect sexual behavior among at-risk adolescents. Individual interviews were conducted with 69 teens, ages 15-18 years, from an alternative high school and a juvenile correctional facility to capture adolescents' early sexual health learning experiences involving family and evaluate their association with teens' recent sexual behavior. Sexual learning narratives were compared among gender and sexual experience groups. Many participants identified family as sexual health information sources. Primary messages recalled: risks of sex, protection, and relationship advice. Many adolescents portrayed learning experiences as negative, cautionary, lacking detail and not always balanced with positive messages. Participants who reported four or more sexual risks were the only group to identify pornography as a sexual health information source. Participants who reported fewer than four sexual risks were most likely to identify family sexual health information sources. Participants identified family members as sources of sexual health information, with variations by gender. Negative/cautionary messages require teens to seek additional sexual information elsewhere (primarily friends/media). Males, in particular, appear to often lack familial guidance/education. Sexual health messages should be tailored to adolescents' needs for practical and sex-positive guidance regarding mechanics of sex and formation of healthy relationships, and balanced with cautions regarding negative consequences.

Fusion is based on high quality full length articles. However, in the words of the journal home page, `Nuclear Fusion welcomes Letters as a means to quickly communicate new, maybe preliminary, results which make a significant advancement of the knowledge in the field. Letters should be comprehensive and short, aiming for four printed pages including figures.' I would like to take the opportunity to reiterate this message and to say that, as Editor, I would welcome the submission of high quality Letters. Publishing procedures In-house, Nuclear Fusion's publishing procedures are subject to continuous scrutiny for potential improvements. Of particular note from 2008 are faster than ever peer review and publishing times that have been achieved despite the very rigorous processing to which submissions are subject. Readers may have noticed the implementation of the new article numbering system, announced by the Publisher, Yasmin McGlashan in 2008 Nucl. Fusion 48 010101. This new scheme gives us more flexibilty and has led to faster online publication. The Nuclear Fusion Office and IOP Publishing Just as the journal depends on the authors and referees, so its success is also due to the tireless and largely unsung efforts of the Nuclear Fusion Office in Vienna and IOP Publishing in Bristol. I would like to express my personal thanks to Maria, Katja, Sophy, Sarah, Rachael and Yasmin for the support that they have given to me, the authors and the referees. Season's Greetings I would like to wish our readers, authors, referees and Board of Editors a successful and happy 2009 and thank them for their contributions to Nuclear Fusion in 2008.

In this work, top-hat cross-section axial crush rail specimens with tailored properties along their length were investigated. These top-hat channels were hot stamped in a fully cooled die set from tailor-welded blanks (TWBs). The blanks were laser-welded and comprised Usibor® 1500-AS joined to Ductibor® 500-AS in 1.2 mm and 1.6 mm thicknesses. Micro-hardness measurements were taken along the length of the formed specimens to map the hardness profile along their length. The effect of gauge thickness on hardness was evaluated. The hardness profile of these TWB parts was compared to that of parts formed using tailored in-die heating (IDH).
To review evidence on the impact of health warning messages on tobacco packages. Articles were identified through electronic databases of published articles, as well as relevant 'grey' literature using the following keywords: health warning, health message, health communication, label and labelling in conjunction with at least one of the following terms: smoking, tobacco, cigarette, product, package and pack. Relevant articles available prior to January 2011 were screened for six methodological criteria. A total of 94 original original articles met inclusion criteria, including 72 quantitative studies, 16 qualitative studies, 5 studies with both qualitative and qualitative components, and 1 review paper: Canada (n=35), USA (n=29) Australia (n=16), UK (n=13), The Netherlands (n=3), France (n=3), New Zealand (n=3), Mexico (n=3), Brazil (n=2), Belgium (n=1), other European countries (n=10), Norway (n=1), Malaysia (n=1) and China (n=1). The evidence indicates that the impact of health warnings depends upon their size and whereas obscure text-only warnings appear to have little impact, prominent health warnings on the face of packages serve as a prominent source of health information for smokers and non-smokers, can increase health knowledge and perceptions of risk and can promote smoking cessation. The evidence also indicates that comprehensive warnings are effective among youth and may help to prevent smoking initiation. Pictorial health warnings that elicit strong emotional reactions are significantly more effective. Health warnings on packages are among the most direct and prominent means of communicating with smokers. Larger warnings with pictures are significantly more effective than smaller, text-only messages.

The traditional bench-to-bedside pipeline involves using model systems and patient samples to provide insights into pathways deregulated in cancer. This discovery reveals new biomarkers and therapeutic targets, ultimately stratifying patients and informing cohort-based treatment options. Precision medicine (molecular profiling of individual tumors combined with established clinical-pathological parameters) reveals, in real-time, individual patient's diagnostic and prognostic risk profile, informing tailored and tumor-specific treatment plans. Here we discuss advances in precision medicine presented at the Irish Association for Cancer Research Annual Meeting, highlighting examples where personalized medicine approaches have led to precision discovery in individual tumors, informing customized treatment programs.

Antireflective surfaces composed of biomimetic sub-wavelength structures that employ the 'moth eye principle' for reflectance reduction are highly desirable in many optical applications such as solar cells, photodetectors and laser optics. We report an efficient approach for the fabrication of antireflective surfaces based on a two-step process consisting of gold nanoparticle mask generation by micellar block copolymer nanolithography and a multi-step reactive ion etching process. Depending on the RIE process parameters nanostructured surfaces with tailored antireflective properties can easily be fabricated that show optimum performance for specific applications.

In predominantly rural Thailand, television is a primary source of HIV/AIDS knowledge. Since 1990, HIV/AIDS warning messages have been aired regularly and repeatedly on television as part of the national strategy to minimize transmission of HIV. The education and prevention messages chosen do more than suggest measures to avoid infection. Within a logic of risk, these messages also define characteristics of people who are signified as threatening agents of infection. In Thailand, prostitutes and drug users are portrayed as the feared Other. Because commercial sex is so widespread, the demarcation of prostitutes as a high risk group signals a diffuse threat not easily subject to conceptual distancing. It is the pervasive and often fear-based associations born of the media material that, in large part, establish the basis for emergent practice when thoughts or actions are triggered by consideration of HIV/AIDS.

Given the lag in tobacco control policies in the southeastern US, we examined differences in reactions to tobacco taxes and related messaging among Southeasterners vs. non-Southeasterners. In 2013, a cross-sectional online survey using quota-based sampling was conducted assessing tobacco use, attitudes/knowledge regarding tobacco taxation, and reactions to related messaging (health, youth prevention, economic impact, individual rights/responsibility, morality/religion, hospitality). Of 2501 participants, 36.7% were past 30-day smokers; 26.7% were Southeasterners. Compared to others, Southeasterners more likely believed that their state was in the bottom 20 states in tobacco taxes (p education, being an infrequent church-attender, and being a current smoker (p's hospitality as more persuasive (p < .05) and anti-tobacco tax messaging related to the unfairness of tobacco taxes to smokers (p = .050) less persuasive. Given that Southeasterners are receptive to increased taxation, other factors must contribute to lagging policy and must be addressed.

The TJ-II autonomous acquisition systems are computers running dedicated applications for programming and controlling data acquisition channels and also integrating acquired data into the central database. These computers are located in the experimental hall and have to be remotely controlled during plasma discharges. A remote control for these systems has been implemented by taking advantage of the message-oriented middleware recently introduced into the TJ-II data acquisition system. Java Message Service (JMS) is used as the messaging application program interface. All the acquisition actions that are available through the system console of the data acquisition computers (starting or aborting an acquisition, restarting the system or updating the acquisition application) can now be initiated remotely. Command messages are sent to the acquisition systems located in the experimental hall close to the TJ-II device by using the messaging software, without having to use a remote desktop application that produces heavy network traffic and requires manual operation. Action commands can be sent to only one or to several/many acquisition systems at the same time. This software is integrated into the TJ-II remote participation system and the acquisition systems can be commanded from inside or outside the laboratory. All this software is integrated into the security framework provided by PAPI, thus preventing non-authorized users commanding the acquisition computers. In order to dimension and distribute messaging services some performance tests of the message oriented middleware software have been carried out. Results of the tests are presented. As suggested by the tests results different transport connectors are used: TCP transport protocol is used for the local environment, while HTTP protocol is used for remote accesses, thereby allowing the system performance to be optimized
Historically, tremendous effort has been put into processing and displaying mission health and safety telemetry data; and relatively little attention has been paid to extracting information from missions time-tagged event log messages. Todays missions may log tens of thousands of messages per day and the numbers are expected to dramatically increase as satellite fleets and constellations are launched, as security monitoring continues to evolve, and as the overall complexity of ground system operations increases. The logs may contain information about orbital events, scheduled and actual observations, device status and anomalies, when operators were logged on, when commands were resent, when there were data drop outs or system failures, and much much more. When dealing with distributed space missions or operational fleets, it becomes even more important to systematically analyze this data. Several advanced information systems technologies make it appropriate to now develop analytic capabilities which can increase mission situational awareness, reduce mission risk, enable better event-driven automation and cross-mission collaborations, and lead to improved operations strategies: Industry Standard for Log Messages. The Object Management Group (OMG) Space Domain Task Force (SDTF) standards organization is in the process of creating a formal standard for industry for event log messages.

Increasingly, health communication practitioners are exploring the use of narrative storytelling to convey health information. For this study, a narrative film was produced to provide information about the human papillomavirus (HPV) and cervical cancer prevention. The storyline centered on Lupita, a young woman recently diagnosed with HPV who informs her family about HPV and the availability of the HPV vaccine for her younger sister. The objective was to examine the roles of identification with characters and narrative involvement (made up of three dimensions: involvement, perceived relevance, and immersion) on perceived response efficacy, perceived severity, and perceived susceptibility to HPV and behavior (discussing the HPV vaccine with a health care provider). A random sample of 450 European American, Mexican American, and African American women between the ages of 25 and 45 years, living in the Los Angeles area, was surveyed by phone before, 2 weeks after, and 6 months after viewing the film. The more relevant women found the narrative to their own lives at 2 weeks, the higher they perceived the severity of the virus and the perceived response efficacy of the vaccine to be. Also at 2 weeks, identifying with characters was positively associated with perceived susceptibility to HPV but negatively associated with perceived severity. At 6 months, identification with specific characters was significantly associated with perceived threat and behavior. These findings suggest that different aspects of narrative health messages should be manipulated depending on the specific beliefs and behaviors being targeted. Implications for narrative message design are discussed.

Messages about sexual relationships, the prevention of pregnancy and disease, education, the empowerment of women, and concern for the environment are increasingly being disseminated to audiences of all ages through the use of entertainment. Ideas are presented in this Enter-Educate approach through popular, enjoyable entertainment in the form of songs, dramas, soap operas, variety shows, and other folk media. This approach can be adapted to be acceptable and effective in all cultures. Yafaman is one such example. It is a drama written and acted by high school students in Cote d'Ivoire which depicts the story of a school girl who learns that her older, married boyfriend is no longer interested in her when she becomes pregnant. After winning the annual national drama contest, Yafaman was televised and broadcast widely in schools and on national networks in francophone Africa. The video has also been dubbed in English for wider use. Popular music has delivered effective messages of sexual responsibility to young adults in Latin America and the Philippines. The US Agency for International Development-funded Population Communication Services project at the Johns Hopkins University supports 36 major Enter-Educate television series and specials, nine radio dramas, three songs, and nine music videos. Other organizations are expanding or experimenting with work in this area. The authors discuss the theoretical basis for Enter-Educate projects and explain that the approach works because it is pervasive, popular, personal, passionate, persuasive, practical, profitable, and proven effective.

Over the past few years there has been an enormous increase in the use of tailored blanks, especially in the automotive industry. Often the sheets for tailored blanks are shear cut, but results have been reported that the allowable sheet gap distance should not exceed 0.1 mm in order to obtain...... sound welds. Laser cutting the sheets may therefore be an alternative to shear cutting, if the cut kerf squareness can be kept below 0.05 mm.In a number of systematic laboratory experiments the effects of the major process parameters in laser cutting have been investigated. Each cut was quantified...... by the squareness, the surface roughness and the burr height. Mild steel as well as high strength steel with and with out galvanisation with thickness' of 0.7(5) and 1.25 were used.In the tests the difference in cut quality between a 5" and a 7.5" focusing lens were tested and the effect of using pulsed mode laser...

The purpose of this study was to evaluate the impact tailored e-mail messages, based on participants' identified needs, have on intentional physical activity. A quasi-experimental design (two groups, repeated measures) in a population of manufacturing workers (73 employees from two distribution plants of a multi-national manufacturer) was used. Significant differences were found between contemplation-staged participants in the intervention and the comparison groups. In the intervention group, 53.3% of the workers moved forward, as opposed to 19.2% in the comparison group (medium effect size = 0.353). Although both the intervention group and the comparison group increased their number of steps, the comparison group's improvement was most likely attributed to a Hawthorne effect. These results are highly promising given the small sample size and limited "dose". The intervention is one most industries could feasibly implement. Such efforts have the potential to significantly impact public health.

A method for passing messages in a parallel computer system constructed as a plurality of compute nodes interconnected as a network where each compute node includes a DMA engine but includes only a limited number of byte counters for tracking a number of bytes that are sent or received by the DMA engine, where the byte counters may be used in shared counter or exclusive counter modes of operation. The method includes using rendezvous protocol, a source compute node deterministically sending a request to send (RTS) message with a single RTS descriptor using an exclusive injection counter to track both the RTS message and message data to be sent in association with the RTS message, to a destination compute node such that the RTS descriptor indicates to the destination compute node that the message data will be adaptively routed to the destination node. Using one DMA FIFO at the source compute node, the RTS descriptors are maintained for rendezvous messages destined for the destination compute node to ensure proper message data ordering thereat. Using a reception counter at a DMA engine, the destination compute node tracks reception of the RTS and associated message data and sends a clear to send (CTS) message to the source node in a rendezvous protocol form of a remote get to accept the RTS message and message data and processing the remote get (CTS) by the source compute node DMA engine to provide the message data to be sent.

However, no research has been conducted to examine the impact of message appeal and message source credibility on consumers' attitude with mediating role of intellectual involvement of consumers and their risk taking level. Purpose - The aim of this study was to examine the impact of appeal and message source credibility on consumers’ attitude with mediating role of consumers’ intellectual involvement and their risk taking level. Design/methodology/approach – The population of this study includes consumers of mobile phones (Samsung, Sony, Nokia, LG and iPhone in Bushehr city (Iran. As the population of the study is unlimited, 430 questionnaires were distributed using available sampling method, and 391 questionnaires were collected and analyzed. Using structural equation modeling, data were analyzed through smart PLS software. Findings –The results show that the appeal and credibility of the message source have impact on consumer attitudes toward the brand. It was also found that intellectual involvement of consumers plays the mediating role in the relationship between message appeal and consumer attitudes toward brand. In the relationship between message source credibility and customer attitude towards the brand, the level of risk taking of people has no mediating role. Research limitations/implications – Data collection tool was questionnaire in this study, and questionnaire has some disadvantages that can affect the results. Additionally, this study was conducted in Bushehr city (Iran. Therefore, we should be cautious in generalizing the findings. Originality/value – In this study, the effect of message appeal and message source credibility on consumer attitude to brand was examined. The risk taking level of consumer and his involvement level were considered
Full Text Available In most forming processes based on tailored blanks, the tool material remains the same as that of sheet metal blanks without tailored properties. A novel concept of lightweight construction for deep drawing tools is presented in this work to improve the forming behavior of tailored blanks. The investigations presented here deal with the forming of tailored blanks of dissimilar strengths using tailored dies made of two different materials. In the area of the steel blank with higher strength, typical tool steel is used. In the area of the low-strength steel, a hybrid tool made out of a polymer and a fiber-reinforced surface replaces the steel half. Cylindrical cups of DP600/HX300LAD are formed and analyzed regarding their formability. The use of two different halves of tool materials shows improved blank thickness distribution, weld-line movement and pressure distribution compared to the use of two steel halves. An improvement in strain distribution is also observed by the inclusion of springs in the polymer side of tools, which is implemented to control the material flow in the die. Furthermore, a reduction in tool weight of approximately 75% can be achieved by using this technique. An accurate finite element modeling strategy is developed to analyze the problem numerically and is verified experimentally for the cylindrical cup. This strategy is then applied to investigate the thickness distribution and weld-line movement for a complex geometry, and its transferability is validated. The inclusion of springs in the hybrid tool leads to better material flow, which results in reduction of weld-line movement by around 60%, leading to more uniform thickness distribution.

This article describes the use of survey research in collaboration with the African American urban community of Georgetown, Jackson, Mississippi to identify and understand prostate cancer knowledge, resource utilization, and health education strategies considered most effective in reaching the community with prostate cancer prevention messages. The study revealed profound needs in disease identification and resources awareness and utilization. Barriers to utilization were identified by participants to include lack of self-efficacy, low self-esteem, lack of trust in the health care system, limited knowledge of prostate pathology, and limited ability to pay. Participants' recommended strategies for reaching the community with prostate cancer education include traditional and nontraditional strategies. The list of recommendations exclude modern-day outlets such as handheld devices, Twitter, Facebook, blogs, wikis, and other Internet-based outlets. The findings provide a road map for program development and an intervention research agenda custom-tailored to the Georgetown community of Jackson, Mississippi.

The NASA Goddard Mission Services Evolution Center (GMSEC) system is a message-based plug-and-play open system architecture used in many of NASA mission operations centers. This presentation will focus on the use of GMSEC standard messages to report and analyze the status of a system and enable the automation of the system's components. In GMSEC systems, each component reports its status using a keep-alive message and also publishes status and activities as log messages. In addition, the components can accept functional directive messages from the GMSEC message bus. Over the past several years, development teams have found ways to utilize these messages to create innovative display pages and increasingly sophisticated approaches to automation. This presentation will show the flexibility and value of the message-based approach to system awareness and automation.

Instant messaging may compromise sleep quality and school performance in adolescents. We aimed to determine associations between nighttime messaging and daytime sleepiness, self-reported sleep parameters, and/or school performance. Students from 3 high schools in New Jersey completed anonymous questionnaires assessing sleep duration, daytime sleepiness, messaging habits, and academic performance. Of the 2,352 students sampled, 1,537 responses were contrasted among grades, sexes, and messaging duration, both before and after lights out. Students who reported longer duration of messaging after lights out were more likely to report a shorter sleep duration, higher rate of daytime sleepiness, and poorer academic performance. Messaging before lights out was not associated with higher rates of daytime sleepiness or poorer academic performance. Females reported more messaging, more daytime sleepiness, and better academic performance than males. There may be an association between text messaging and school performance in this cohort of students. © The Author(s) 2016.

Anthropogenic climate change (ACC) poses a threat to the safety and well-being of the United States. For science educators, the first step to mitigating this problem is helping the public understand the science of climate change so they make knowledgeable political and personal choices. However, some Americans remain unconvinced that the recent rapid rise of Earth's temperature is caused by human activities. A portion of anti-climate change information comes from groups that stand to lose power and revenue if the public begins to favor greenhouse gas limiting policies. These groups thwart policy initiatives through the production and dissemination of anti-ACC messages to news media, blogs, and among politicians. It is important for educators to understand these dissenter messages in order to avoid inadvertently using them. In earlier work, we developed a Likert-type survey instrument from online videos of authentic dissenter messages. Using this instrument and exploratory factor analysis (N=133), we identified five categories of counter ACC arguments: naïve statements which either use scientific misconceptions to dismiss or attack the science of ACC; sophisticated scientific statements which imply warming is not anthropogenic; arguments that assert recent changes are natural or out of our control; arguments that imply current warming is simply part of a larger cycle; and statements that highlight benefits of a warming climate. For the present study we validated the instrument using multiple methods including confirmatory factor analysis (N=151). Results suggest our instrument may identify how different populations agree with misleading ACC material. Here we explore two questions: (1) does a relationship exist between dissenter message agreement and primary news source? and (2) does a relationship exist between dissenter statement agreement and ACC acceptance? This information could be used to generate tailored resources that could inoculate people from misleading

The proposed LAMPF-II accelerator has a 60-Hz booster synchrotron and a 3-Hz main ring. To provide a vacuum enclosure inside the magnets with low eddycurrent losses and minimal field distortion, yet capable of carrying rf image currents and providing beam stabilization, we propose an innovative combination pipe. Structurally, the enclosure is high-purity alumina ceramic, which is strong, radiation resistant, and has good vacuum properties. Applied to the chamber are thin, spaced, silver conductors using adapted thick-film technology. The conductor design can be tailored to the stabilization requirements, for example, longitudinal conductors for image currents, circumferential for transverse stabilization. The inside of the chamber has a thin, resistive coating to avoid charge build-up. The overall 60-Hz power loss is less than 100 W/m

Manipulation and control of the electronic states of atoms provides an exciting new area of research in atomic physics with important potential applications. Such control can be achieved using ``designer'' electromagnetic pulses whose strengths are comparable to the Coulomb electric field and whose durations are of the order of the classical orbital period of the atom. Coherent control of the electron dynamics requires complete knowledge of the initial state as well as of the pulses whose shapes can be carefully tailored at will. In this presentation we report on experimental and theoretical control of atomic wavefunctions using very high-n Rydberg atoms and designer half-cycle pulses. We discuss new possibilities in producing and probing coherent atomic wavepackets and the first realization of the periodically kicked atom, a paradigmatic system of non-linear dynamics using a superposition of half-cycle pulses.

In the quest for less toxic and cleaner methods of nanomaterials production, recent developments in the biosynthesis of nanoparticles have underscored the important role of microorganisms. Their intrinsic ability to withstand variable extremes of temperature, pressure, and pH coupled with the minimal downstream processing requirements provide an attractive route for diverse applications. Yet, controlling the dispersity and facile tuning of the morphology of the nanoparticles of desired chemical compositions remains an ongoing challenge. In this Focus Review, we critically review the advances in nanoparticle synthesis using microbes, ranging from bacteria and fungi to viruses, and discuss new insights into the cellular mechanisms of such formation that may, in the near future, allow complete control over particle morphology and functionalization. In addition to serving as paradigms for cost-effective, biocompatible, and eco-friendly synthesis, microbes hold the promise for a unique template for synthesis of tailored nanoparticles targeted at therapeutic and diagnostic platform technologies. © 2015 Wiley Periodicals, Inc.

The Message Reporting System (MRS) in the ATLAS data acquisition system (DAQ) is one package of the Online Software which acts as a glue of various elements of DAQ, High Level Trigger (HLT) and Detector Control System (DCS). The aim of the MRS is to provide a facility which allows all software components in ATLAS to report messages to other components of the distributed DAQ system. The processes requiring a MRS are on one hand applications that report error conditions or information and on the other hand message processors that receive reported messages. A message reporting application can inject one or more messages into the MRS at any time. An application wishing to receive messages can subscribe to a message group according to defined criteria. The application receives messages that fulfill the subscription criteria when they are reported to MRS. The receiver message processing can consist of anything from simply logging the messages in a file/terminal to performing message analysis. The inter-process comm...

With the popularity of social media, Twitter has become an important tool to promote health literacy. However, many health-related messages on Twitter are dead-ended and cannot reach many people. This is unhelpful for health literacy promotion. This article aims to examine the features of online health food messages that people like to retweet. We adopted rumour theory as our theoretical foundation and extracted seven characteristics (i.e. emotional valence, attractiveness, sender's authoritativeness, external evidence, argument length, hashtags, and direct messages). A total of 10,025 health-related messages on Twitter were collected, and 1496 messages were randomly selected for further analysis. Each message was treated as one unit and then coded. All the hypotheses were tested with logistic regression. Emotional valence, attractiveness, sender's authoritativeness, argument length, and direct messages in a Twitter message had positive effects on people's retweet behaviour. The effect of external evidence was negative. Hashtags had no significant effect after consideration of other variables. Online health food messages containing positive emotions, including pictures, containing direct messages, having an authoritative sender, having longer arguments, or not containing external URLs are more likely to be retweeted. However, a message only containing positive or negative emotions or including direct messages without any support information will not be retweeted.

This perspective paper describes processes in the development of an evidence-based fall prevention curriculum for community health workers/promotores (CHW/P) that highlights the development of the curriculum and addresses: (1) the need and rationale for involving CHW/P in fall prevention; (2) involvement of CHW/P and content experts in the curriculum development; (3) best practices utilized in the curriculum development and training implementation; and (4) next steps for dissemination and utilization of the CHW/P fall prevention curriculum. The project team of CHW/P and content experts developed, pilot tested, and revised bilingual in-person training modules about fall prevention among older adults. The curriculum incorporated the following major themes: (1) fall risk factors and strategies to reduce/prevent falls; (2) communication strategies to reduce risk of falling and strategies for developing fall prevention plans; and (3) health behavior change theories utilized to prevent and reduce falls. Three separate fall prevention modules were developed for CHW/P and CHW/P Instructors to be used during in-person trainings. Module development incorporated a five-step process: (1) conduct informal focus groups with CHW/P to inform content development; (2) develop three in-person modules in English and Spanish with input from content experts; (3) pilot-test the modules with CHW/P; (4) refine and finalize modules based on pilot-test feedback; and (5) submit modules for approval of continuing education units. This project contributes to the existing evidence-based literature by examining the role of CHW/P in fall prevention among older adults. By including evidence-based communication strategies such as message tailoring, the curriculum design allows CHW/P to personalize the information for individuals, which can result in an effective dissemination of a curriculum that is evidence-based and culturally appropriate.

Focusing on several message features that are prominent in antismoking campaign literature, this content-analytic study examines 934 antismoking video clips on YouTube for the following characteristics: message sensation value (MSV) and three types of message appeal (threat, social and humor). These four characteristics are then linked to YouTube's interactive audience response mechanisms (number of viewers, viewer ratings and number of comments) to capture message reach, viewer preference and viewer engagement. The findings suggest the following: (i) antismoking messages are prevalent on YouTube, (ii) MSV levels of online antismoking videos are relatively low compared with MSV levels of televised antismoking messages, (iii) threat appeals are the videos' predominant message strategy and (iv) message characteristics are related to viewer reach and viewer preference.

Marketers planning promotional campaigns ask questions to boost the odds that the messages will be accepted: Who should receive each message? What should be its content? How should we deliver it? The one question they rarely ask is, when should we deliver it? That's too bad, because in marketing, timing is arguably the most important variable of all. Indeed, there are moments in a customer's relationship with a business when she wants to communicate with that business because something has changed. If the company contacts her with the right message in the right format at the right time, there's a good chance of a warm reception. The question of "when" can be answered by a new computer-based model called "dialogue marketing," which is, to date, the highest rung on an evolutionary ladder that ascends from database marketing to relationship marketing to one-to-one marketing. Its principle advantages over older approaches are that it is completely interactive, exploits many communication channels, and is "relationship aware": that is, it continuously tracks every nuance of the customer's interaction with the business. Thus, dialogue marketing responds to each transition in that relationship at the moment the customer requires attention. Turning a traditional marketing strategy into a dialogue-marketing program is a straightforward matter. Begin by identifying the batch communications you make with customers, then ask yourself what events could trigger those communications to make them more timely. Add a question or call to action to each message and prepare a different treatment or response for each possible answer. Finally, create a series of increasingly urgent calls to action that kick in if the question or call to action goes unanswered by the customer. As dialogue marketing proliferates, it may provide the solid new footing that Madison Avenue seeks.

Recently, antioxidants have taken centre stage in media and advertising messages. While 80% of Canadians think they are well-informed about nutrition, many are confused about the health effects of specific nutrients. Forty-six percent of Canadians seek information from newspapers and books, and 67% of women rely on magazines. We examined the content and accuracy of antioxidant health messages in Canadian women's magazines. The top three Canadian magazines targeted at women readers were selected. A screening tool was developed, pilot tested, and used to identify eligible articles. A coding scheme was created to define variables, which were coded and analyzed. Seventy-seven percent of 36 magazine issues contained articles that mentioned antioxidants (n=56). Seventy-one percent (n=40) of articles reported positive health effects related to antioxidant consumption, and 36% and 40% of those articles framed those effects as definite and potential, respectively (p<0.01). The articles sampled conveyed messages about positive antioxidant health effects that are not supported by current evidence. Improved standards of health reporting are needed. Nutrition professionals may need to address this inaccuracy when they develop communications on antioxidants and health risk.
Since its inception in 2007, ZeroMQ has defined a new product category of thin, fast, open source message transports. This little library has now grown into a large, vibrant community of projects tied together with standard protocols and APIs. Applications, written in any language, talk to each other over TCP, multicast, or inproc transports, using a single socket-based API, and a set of "patterns" (pub-sub, request-reply, dealer-router, pipeline). ZeroMQ handles message framing, batching, and I/O, but ignores aspects like serialization and persistence. By focussing on the essentials, and acting as a toolkit rather than a pre-packaged solution, ZeroMQ turns the complex problem of distributed computing into a relatively simple recipe. About the speaker Pieter Hintjens is a writer, programmer, and public speaker who has spent decades building large software systems, organizations, and businesses.

This paper explores whether, and to what extent, national newspaper messages tally with public perceptions about meticillin-resistant Staphylococcus aureus (MRSA). It compares research on media messages about MRSA with interview data gathered from a demographically diverse sample of 60 people interviewed from the Greater London area. Across the interview sample there was a shared consensus that most people associated MRSA not with the history of antibiotic use, but with dirty and poorly managed hospitals. Some media messages, such as blaming MRSA on the alleged 'management culture' of the NHS, seemed to capture the Zeitgeist, whereas others, in particular the 'celebrity victims' of MRSA, did not seem to resonate with the audience. This study also found that ideas based on scientific understandings about germ theory and the immune system were held alongside folklore such as miasmic theory. The comparison of media and mind thus points to the existence of pre-scientific understandings of germs, contagion and blame in parallel with the biomedical story in the minds of the public. The findings contribute to our understanding of the public and patients' views of this infection.

Health communication via mass media is an important strategy when targeting risky drinking, but many questions remain about how health messages are processed and how they unfold their effects within receivers. Here we examine how the brains of young adults-a key target group for alcohol prevention-'tune in' to real-life health prevention messages about risky alcohol use. In a first study, a large sample of authentic public service announcements (PSAs) targeting the risks of alcohol was characterized using established measures of message effectiveness. In the main study, we used inter-subject correlation analysis of fMRI data to examine brain responses to more and less effective PSAs in a sample of young adults. We find that more effective messages command more similar responses within widespread brain regions, including the dorsomedial prefrontal cortex, insulae and precuneus. In previous research, these regions have been related to processing narratives, emotional stimuli, self-relevance and attention towards salient stimuli. The present study thus suggests that more effective health prevention messages have greater 'neural reach', i.e. they engage the brains of audience members' more widely. This work outlines a promising strategy for assessing the effects of health communication at a neural level. © The Author (2017). Published by Oxford University Press.

Message fatigue refers to a state of being exhausted and tired of prolonged exposure to similarly-themed messages (e.g., anti-obesity messages; So, Kim, & Cohen, 2017). This study tests a mediational model that accounts for how one's preexisting fatigue toward anti-obesity messages may contribute to two different types of resistance-reactance and disengagement-toward an incoming anti-obesity message, which, in turn, reduce intention to adopt weight-management behaviors advocated in the message. The proposed model was tested in an experimental study (N = 312) involving a sample of overweight or obese adults in the United States. In the meditational model, reactance significantly mediated the negative effects of message fatigue on intention to adopt only one of four weight-management behaviors promoted in the message. However, inattention, which was an operationalization of disengagement, significantly mediated the negative effects of message fatigue on behavioral intention to adopt all four weight-management behaviors. This study urges future research on message fatigue and resistance to persuasion to consider disengagement with a message as a significant barrier to effective health communication and to devise ways to increase engagement with messages communicating "overtaught" health issues.

A prototype unified message broadcast system to handle the site-wide distribution of all control system messages for the Superconducting Super Collider is presented. The messages are assembled in the control room area and encapsulated for transmission via a general fiber-optic link system to devices distributed throughout 70 miles of tunnels. An embedded timing signal is used by the distribution system to ensure that messages arrive at all devices simultaneously. Devices receive messages using a special receiver sub-system. A simple version of this system is to be used in the Accelerator Systems String Test (ASST) at the SSC site in 1991. 3 refs., 6 figs., 1 tab
Social media users post messages about health goals and behaviors to online social networks. Compared with more traditional sources of health communication such as physicians or health journalists, peer sources are likely to be perceived as more socially close or similar, which influences how messages are processed. This experimental study uses construal level theory of psychological distance to predict how mediated health messages from peers influence health-related cognition and behavioral intention. Participants were exposed to source cues that identified peer sources as being either highly attitudinally and demographically similar to or different from participants. As predicted by construal level theory, participants who perceived sources of social media health messages as highly similar listed a greater proportion of beliefs about the feasibility of health behaviors and a greater proportion of negative beliefs, while participants who perceived sources as more dissimilar listed a greater proportion of positive beliefs about the health behaviors. Results of the study could be useful in determining how health messages from peers could encourage individuals to set realistic health goals.

Full Text Available This paper is an application of Relevance Theory for the interpretation of short messaging service (SMS text messages emanating from Nigerian telecommunications companies to their subscribers. The aim of the research was to identify and describe the manipulative strategies employed by Nigerian telecommunications companies to induce subscribers to part with their money through sales promotion lotteries. 100 SMS texts were purposively extracted from the cell phones of randomly selected residents of Lagos Nigeria who had received promotional SMS text messages from three major Nigerian telecommunications companies. Using Sperber and Wilson's Relevance Theory (1995 as its theoretical framework, the paper described the manipulative use of SMS by Nigerian telecommunications companies. The analysis revealed that SMS text messages were encoded to achieve maximization of relevance through explicature and implicature; contextual implication and strengthening; and the reduction of processing effort through violating the maxim of truthfulness and the creative use of graphology. The paper concludes that SMS text-messages were used manipulatively by Nigerian telecommunications companies to earn indirect income from sales promotion lottery.

NASA's Marshall Space Flight Center (MSFC) has developed an integrated systems engineering approach to promote a culture of tailoring for program and project policy requirements. MSFC's culture encourages and supports tailoring, with an emphasis on risk-based decision making, for enhanced affordability and efficiency. MSFC's policy structure integrates the various Agency requirements into a single, streamlined implementation approach which serves as a "one-stop-shop" for our programs and projects to follow. The engineers gain an enhanced understanding of policy and technical expectations, as well as lesson's learned from MSFC's history of spaceflight and science missions, to enable them to make appropriate, risk-based tailoring recommendations. The tailoring approach utilizes a standard methodology to classify projects into predefined levels using selected mission and programmatic scaling factors related to risk tolerance. Policy requirements are then selectively applied and tailored, with appropriate rationale, and approved by the governing authorities, to support risk-informed decisions to achieve the desired cost and schedule efficiencies. The policy is further augmented by implementation tools and lifecycle planning aids which help promote and support the cultural shift toward more tailoring. The MSFC Customization Tool is an integrated spreadsheet that ties together everything that projects need to understand, navigate, and tailor the policy. It helps them classify their project, understand the intent of the requirements, determine their tailoring approach, and document the necessary governance approvals. It also helps them plan for and conduct technical reviews throughout the lifecycle. Policy tailoring is thus established as a normal part of project execution, with the tools provided to facilitate and enable the tailoring process. MSFC's approach to changing the culture emphasizes risk-based tailoring of policy to achieve increased flexibility, efficiency

Living in violent neighborhoods has been shown to alter adolescent's social cognitions and increase aggressive behavior. A similar process may also occur for parents and result in parental support of aggressive behavior. This research examines the influence of perceived neighborhood violence and neighborhood collective efficacy on parental attitudes toward violence and the messages they give their adolescent children about how to resolve interpersonal conflict. Data were collected from 143 African American parents and their adolescent children recruited from three inner-city middle schools to participate in a parenting intervention. Models were fit using structural equation modeling in Mplus. Contrary to expectations, exposure to neighborhood violence was not predictive of either aggressive attitudes or conflict solutions for parents or adolescents. Rather, a mixed effect was found for neighborhood collective efficacy, with higher perceived neighborhood collective efficacy related to less violent attitudes for adolescents but not for parents. Collective efficacy also predicted the messages that parents gave their adolescents about interpersonal conflict, with higher collective efficacy related to messages that were less supportive of violence. Parent and adolescent perception of neighborhood collective efficacy influences the messages that adolescents receive about interpersonal conflict resolution. This suggests that for parents living in violent neighborhoods, their appraisal of the neighborhood is more important in shaping conflict resolution messages than their own experiences with violence. Parent- and family-based programs to prevent youth violence need to address neighborhood factors that influence the messages adolescents receive about how to resolve conflict.

Many liver transplantation programs require documented alcohol sobriety prior to United Network for Organ Sharing (UNOS) listing. This pilot study examined the feasibility of the first mobile, alcohol relapse prevention intervention for liver transplant patients with alcoholic liver disease (ALD). This was a randomized 8-week pilot feasibility trial of a text message-based alcohol intervention. In-treatment assessment was conducted at 4 weeks (4W), and immediate posttreatment assessment was conducted at 8W. Participants were liver transplant candidates (N = 15) diagnosed with ALD who reported at least 1 drinking episode in the past year. Primary feasibility outcomes were percent of messages responded to and posttreatment intervention satisfaction ratings. Preliminary clinical efficacy outcomes were any biologically confirmed alcohol consumption, stress, abstinence self-efficacy, and alcohol craving. On feasibility outcomes, participants responded to 81% of messages received and reported high rates of intervention satisfaction, looked forward to receiving the messages, and found it easy to complete the intervention. On preliminary efficacy outcomes, zero participants in the text message (TM) had positive urine alcohol tests at 8W. Two of the 6 participants in standard care (SC) tested positive at 8W. No effects were seen on craving. For stress, a condition × time interaction emerged. TM participants had less stress at 4W and 8W compared with SC at baseline. They maintained their stress level during the intervention. For self-efficacy, a trend for condition effect emerged. TM participants had higher self-efficacy than SC participants. Participants reported high satisfaction with the intervention, looked forward to the messages, and found it easy to complete. Participants who received the intervention had better treatment outcomes than those who received standard care. They maintained higher levels of self-efficacy and lower stress.

Full Text Available Abstract Background Evolution has selected for organisms that benefit from genetically encoded cell-cell communication. Engineers have begun to repurpose elements of natural communication systems to realize programmed pattern formation and coordinate other population-level behaviors. However, existing engineered systems rely on system-specific small molecules to send molecular messages among cells. Thus, the information transmission capacity of current engineered biological communication systems is physically limited by specific biomolecules that are capable of sending only a single message, typically “regulate transcription.” Results We have engineered a cell-cell communication platform using bacteriophage M13 gene products to autonomously package and deliver heterologous DNA messages of varying lengths and encoded functions. We demonstrate the decoupling of messages from a common communication channel via the autonomous transmission of various arbitrary genetic messages. Further, we increase the range of engineered DNA messaging across semisolid media by linking message transmission or receipt to active cellular chemotaxis. Conclusions We demonstrate decoupling of a communication channel from message transmission within engineered biological systems via the autonomous targeted transduction of user-specified heterologous DNA messages. We also demonstrate that bacteriophage M13 particle production and message transduction occurs among chemotactic bacteria. We use chemotaxis to improve the range of DNA messaging, increasing both transmission distance and communication bit rates relative to existing small molecule-based communication systems. We postulate that integration of different engineered cell-cell communication platforms will allow for more complex spatial programming of dynamic cellular consortia.

This study was designed to measure the effects of subliminal backward messages on attitudes. It was hypothesized that subliminal backward-recorded messages would influence the attitudes of listeners. Three subliminal backward-recorded messages from a popular song were used. 82 undergraduates were randomly assigned to one of four conditions: a three-message group heard a tape containing the backward messages recorded three times in succession, a six-message group heard a tape with the same backward messages recorded six times in succession, two control groups heard nonbackward recorded music. No statistically significant differences were found between the groups on a posttape attitude questionnaire. The results are discussed in terms of unconscious processing and the tricomponent theory of attitudes and attitude change.

Evidence-based persuasive message design can be informed by dependable research-based generalizations about the relative persuasiveness of alternative message-design options. Five propositions are offered as specifying what constitutes the best evidence to underwrite such generalizations: (1) The evidence should take the form of replicated randomized trials in which message features are varied. (2) Results should be described in terms of effect sizes and confidence intervals, not statistical significance. (3) The results should be synthesized using random-effects meta-analytic procedures. (4) The analysis should treat attitudinal, intention, and behavioral assessments as yielding equivalent indices of relative persuasiveness. (5) The replications included in research syntheses should not be limited to published studies or to English-language studies.

Tailoring is further evolution of an application after deployment in order to adapt it to requirements that were not accounted for in the original design. End-user tailorability has been extensively researched in applied computer science from HCl and software engineering perspectives. Tailorability allows coping with flexibility requirements, decreasing maintenance and development costs of software products. In general, dynamic or diverse software requirements constitute the need for implementing end-user tailorability in computer systems. In accelerator physics research the factor of dynamic requirements is especially important, due to frequent software and hardware modifications resulting in correspondingly high upgrade and maintenance costs. In this work we introduce the results of feasibility study on implementing end-user tailorability in the software for accelerator control system, considering the design and implementation of distributed monitoring application for 12 GeV KEK Proton Synchrotron as an example. The software prototypes used in this work are based on a generic tailoring platform (VEDICI), which allows decoupling of tailoring interfaces and runtime components. While representing a reusable application-independent framework, VEDICI can be potentially applied for tailoring of arbitrary compositional Web-based applications

Full Text Available The development of ICT media made way for a new form of folklore communication. Newly developed media, such as mobile phones, make it possible for their users to participate in electronically mediated communication, thus approaching the form of oral communication. The exchange of special type of SMS text messages represents a new way of transmitting contemporary folklore short forms. These messages use poetic language, they have standard style themes, patterns and formulas, and they form different genres and categories corresponding with already existing familiar folklore forms. The communication process that happens during the exchange of these messages also has folklore’s characteristics: it takes place within small groups, the communication is informal, the texts circulate in chain style, and undergo different transformation which generates the making of variants, etc. This form of electronic folklore is especially popular among teenagers, where it’s social functions and meanings are also most emphasized. Within this population, it adds to an older tradition of children’s written folklore poetry albums. Like poetry albums, SMS exchange influences the development of girls’ gender identity, providing also a socially defined channel for contacts between the sexes. It also functions as a mechanism of socialization and stratification within the group. At the same time, it creates a new field of meaning, which derives from the very media’s novelty and significance. In this sense, the exchange of SMS represents a symbolic act of acknowledging one’s belonging to the group of mobile telephone users. In this way, a new phenomenon is being symbolically processed through a new form of folklore.
Full Text Available Audiovisual programs are meant to be seen and heard simultaneously. Screen translators have to take the verbal, acoustic and visual elements of audiovisual works into consideration. However they translate only the verbal content of the message. In the following article we focus on one of the main modalities for audiovisual translation, namely the subtitling. Our aim is to describe the specificity of screen translation and to think about the impact of subtitling process on the final product, that is on translation. We will show how translators take advantage of the presence of the verbal (dialogues and the visual (screen codes with the aim of reducing an original text.
This article presents the results of a study of two SMS services aimed at providing young people with information on cannabis and helping them to reduce their consumption of the drug. The attitude of the 12 participants in the study towards the SMS services is generally positive, but they prefer...... factual information to advice and counselling. The messages prompt reflection and awareness among the recipients, and their repetitive, serial nature plays a significant part in the process of change. This is especially true of the young people whose use of cannabis is recreational. For them, the SMS...

For several decades, myths about the brain - neuromyths - have persisted in schools and colleges, often being used to justify ineffective approaches to teaching. Many of these myths are biased distortions of scientific fact. Cultural conditions, such as differences in terminology and language, have contributed to a 'gap' between neuroscience and education that has shielded these distortions from scrutiny. In recent years, scientific communications across this gap have increased, although the messages are often distorted by the same conditions and biases as those responsible for neuromyths. In the future, the establishment of a new field of inquiry that is dedicated to bridging neuroscience and education may help to inform and to improve these communications.

Tobacco smoking is a leading cause of preventable mortality and morbidity. Since 1991, the Western Australian Health Promotion Foundation (Healthway) has sponsored the arts and sport in exchange for cigarette smoke-free events, smoke-free policies and the promotion of anti-smoking messages (e.g. Quit, Smoke Free or Smarter than Smoking). As health promoters often look for innovative and effective settings to advocate health, and as the approach of sponsoring the arts to promote health to the general population is uncommon, the purpose of this study was to evaluate the effectiveness of 'health in arts' by measuring the cognitive impact (message awareness, comprehension, acceptance and intention) of promoting anti-smoking messages at arts events, and comparing findings to sports events, a more traditional health promotion setting. A secondary analysis of the 2004-2009 Healthway Sponsorship Monitor data was conducted. A total of 12 arts events (n = 592 respondents) and 9 sports events (n = 420 respondents) sponsored by Healthway to promote an anti-smoking message were evaluated. The study was cross-sectional in design. Participants were residents of Western Australia aged 15 years or above and attended events as part of an audience or as a spectator. Descriptive and regression analyses were conducted. After adjustment for demographic variables, smoking status and clustering, arts events were found to be as effective in promoting anti-smoking message awareness, comprehension and acceptance and twice as effective on intention to act (p = .03) compared with sports events. This study provides evidence of the effectiveness of arts sponsorship to promote health to the general population, that is, health in arts. Promoting an anti-smoking message in arts settings was as, or more, effective than in sports settings. Results suggest that the arts should be utilised to communicate and reinforce anti-smoking messages to the general population. The suitability of the arts to

We used ecological momentary assessment (EMA) to examine young adults' attitudes towards pro-tobacco messages encountered in real time and their association with intentions to use tobacco. Young adults (N = 92, ages 18-29) recorded sightings of marketing or social media related to tobacco in real time via mobile app for 28 days. Participants reported message characteristics, their attitudes towards the message, and intentions to use the depicted product for each submission. We used generalized linear mixed models to examine factors related to attitude towards message and intentions to use tobacco. Messages depicting e-cigarettes (p < .001) or hookah (p < .05) were associated with significantly more favorable attitudes compared with traditional cigarettes. Positive attitude towards the message was significantly associated with intention to use the depicted product (p < .001). Messages depicting e-cigarettes and hookah were significantly associated with higher intention to use. Message source was not significantly related to attitudes towards the message or product use intentions. Marketing featuring e-cigarettes and hookah is an important target for future regulation. Given that pro-tobacco and e-cigarette messages are prevalent online, future research should consider the Internet and social media as important venues for counter-marketing and intervention efforts.
Multicopy routing strategies have been considered the most applicable approaches to achieve message delivery in Delay Tolerant Networks (DTNs). Epidemic routing and two-hop forwarding routing are two well-reported approaches for delay tolerant networks routing which allow multiple message replicas to be launched in order to increase message delivery ratio and/or reduce message delivery delay. This advantage, nonetheless, is at the expense of additional buffer space and bandwidth overhead. Thus, to achieve efficient utilization of network resources, it is important to come up with an effective message scheduling strategy to determine which messages should be forwarded and which should be dropped in case of buffer is full. This paper investigates a new message scheduling framework for epidemic and two-hop forwarding routing in DTNs, such that the forwarding/dropping decision can be made at a node during each contact for either optimal message delivery ratio or message delivery delay. Extensive simulation results show that the proposed message scheduling framework can achieve better performance than its counterparts.

There is very little insight into the psychosocial characteristics of young adults susceptible to waterpipe tobacco use and their reactions to messages about harms of waterpipe tobacco smoking (WTS). We investigated how young adults who were or were not susceptible to WTS differed on various characteristics and their reactions to messages about WTS harms. Young adults ages 18 to 30 who had never used waterpipe tobacco were recruited through an online crowdsourcing site. Participants were stratified on susceptibility status (susceptible or not) and randomized to receive messages about harms and addictiveness of WTS or a control condition that received no messages. Participants' perceptions of risk and worry, their attitudes toward, and willingness/curiosity to try WTS were assessed. Compared to nonsusceptible participants, susceptible participants perceived themselves to be at lower risk and worried less about harms and addictiveness of WTS, had more positive attitudes toward use, and expressed a greater willingness and curiosity to try it. Among susceptible participants, messages decreased willingness/curiosity to try WTS; messages had no effect on nonsusceptible participants. The message effects among susceptible participants were explained by more negative attitudes and less ambivalence toward WTS. Susceptible young adults' psychosocial characteristics place them at high risk for future uptake of WTS. Brief public health messages about harm and addiction may deter susceptible young adults' willingness to try WTS and prevent WTS initiation and progression. Findings suggest that in order to curb the initiation of WTS among susceptible young adults, interventions should target risk appraisals and attitudes toward WTS. © The Author 2016.

Narrative messages may be an effective strategy to increase risk perceptions and motivate preventive behaviours related to cancer. The aim of this research was to examine associations between narrative transportation (i.e. psychological absorption into a narrative), risk perceptions, and intentions following narrative messages about skin cancer. In two studies, women who reported indoor tanning read first-person narrative messages about skin cancer. We examined associations between narrative transportation and the women's responses to the narratives, including risk perceptions for skin cancer and behaviour intentions to reduce risk. Associations between transportation, knowledge and worry were also examined. Greater transportation was associated with higher intentions to perform skin self-examination, talk to one's doctor about skin cancer, and look for more information. Greater transportation was also associated with higher gut feelings of risk and higher worry about skin cancer, but not deliberative risk perceptions or knowledge from the message. Additional analyses showed that after controlling for risk perception and worry, transportation had unique associations with some behaviour intentions. Findings suggest that narrative transportation may be an important component to the persuasion of cancer narratives. Future research should explore ideas such as the role of the experiential system in narratives' influence.

We tested the feasibility and effectiveness of an alcohol counseling intervention delivered via personalized text messages for college students with problem alcohol use. College students aged 18-23 completed online substance use and mental health questionnaires that served as a screening tool for problem alcohol use. We invited students who screened positive to be randomized to intervention (n = 8) or control groups (n = 10) and assessed them at 1 month after they received their last text message. The intervention group received between four and six text messages daily for 4 days that required brief participant responses during the week following the web-based baseline assessment. Participants in the intervention group could also request booster texts for additional support. We personalized all texts, using data collected at baseline. Using a repeated measures ANOVA, we found that compared to the control group, the intervention group increased in readiness to change from baseline to follow-up (p confidence in their ability to change drinking behavior, and an increase in intentions to reduce alcohol use. These exploratory results indicate that the automated texting program we developed works well with college students and that text messaging as a means to deliver preventive interventions is a promising delivery platform.
Full Text Available Severe environments imposed by new technologies demand new materials with better properties and ensured reliability. The intrinsic brittleness of ceramics has forced scientists to look for new materials and processing routes to improve the mechanical behaviour of ceramics in order to allow their use under severe thermomechanical conditions. The laminate approach has allowed the fabrication of a new family of composite materials with strength and reliability superior to those of monolithic ceramics with microstructures similar to those of the constituent layers. The different ceramic laminates developed since the middle 1970´s can be divided in two large groups depending on whether the development of residual stresses between layers is the main design tool. This paper reviews the developments in the control and tailoring of residual stresses in ceramic laminates. The tailoring of the thickness and location of layers in compression can lead to extremely performing structures in terms of strength values and reliability. External layers in compression lead to the strengthening of the structure. When relatively thin and highly compressed layers are located inside the material, threshold strength, crack bifurcation and crack arrest during fracture occur.

Owing to their reduced dimensions, the magnetic properties of ultrathin magnetic films and multilayers, e.g. magnetic anisotropies and exchange coupling, often depend strongly on the surface and interface structure. In addition, chemical composition, crystallinity, grain sizes and their distribution govern the magnetic behaviour. All these structural properties can be modified by light-ion irradiation in an energy range of 5-150 keV due to the energy loss of the ions in the solid along their trajectory. Consequently the magnetic properties can be tailored by ion irradiation. Similar effects can also be observed using Ga + ion irradiation, which is the common ion source in focused ion beam lithography. Examples of ion-induced modifications of magnetic anisotropies and exchange coupling are presented. This review is limited to radiation-induced structural changes giving rise to a modification of magnetic parameters. Ion implantation is discussed only in special cases. Due to the local nature of the interaction, magnetic patterning without affecting the surface topography becomes feasible, which may be of interest in applications. The main patterning technique is homogeneous ion irradiation through masks. Focused ion beam and ion projection lithography are usually only relevant for larger ion masses. The creation of magnetic feature sizes below 50 nm is shown. In contrast to topographic nanostructures the surrounding area of these nanostructures can be left ferromagnetic, leading to new phenomena at their mutual interface. Most of the material systems discussed here are important for technological applications. The main areas are magnetic data storage applications, such as hard magnetic media with a large perpendicular magnetic anisotropy or patterned media with an improved signal to noise ratio and magnetic sensor elements. It will be shown that light-ion irradiation has many advantages in the design of new material properties and in the fabrication technology of

Tailor Welded Blanks (TWB) technology is one of the several approaches that have been used to reduce the weight of the automobile body. TWBs are made up of two or more blanks having different/same properties (geometry, material etc.) prior to forming. The formability of these blanks depends on material and geometric parameters like strength ratio and thickness ratio. The study of these blanks can be classified on the basis of the weld orientation chosen viz. transverse weld or longitudinal weld with respect to the major straining direction.This paper studies the formability issues related to transverse TWB by FE simulation. The formability is assessed by analyzing tensile and Limit Dome Height (LDH) tests. The weld region is assumed to be a line in all the simulations. While modeling the tensile test, ultimate tensile strength (UTS) and elongation are monitored, and in LDH testing, pole height and maximum load (in near plane strain condition) are monitored. LDH testing shows that as thickness ratio increases, the load bearing capacity and the pole height decreases. There is a contribution from both the thicker and the thinner blank to the overall deforming volume. Failure location analysis shows that there is an abrupt change in the location of the failure from punch nose region to weld line region as the thickness ratio reaches a critical magnitude (1.08).The study of material properties shows that as the yield strength ratio (S ratio) and strain hardening exponent ratio (N ratio) between the blanks increases, the maximum load which the blank can sustain without failure (UTS) increases. This becomes constant and comparable to that of single sheet at higher N and S ratios

Abstract Health communication via mass media is an important strategy when targeting risky drinking, but many questions remain about how health messages are processed and how they unfold their effects within receivers. Here we examine how the brains of young adults—a key target group for alcohol prevention—‘tune in’ to real-life health prevention messages about risky alcohol use. In a first study, a large sample of authentic public service announcements (PSAs) targeting the risks of alcohol was characterized using established measures of message effectiveness. In the main study, we used inter-subject correlation analysis of fMRI data to examine brain responses to more and less effective PSAs in a sample of young adults. We find that more effective messages command more similar responses within widespread brain regions, including the dorsomedial prefrontal cortex, insulae and precuneus. In previous research, these regions have been related to processing narratives, emotional stimuli, self-relevance and attention towards salient stimuli. The present study thus suggests that more effective health prevention messages have greater ‘neural reach’, i.e. they engage the brains of audience members’ more widely. This work outlines a promising strategy for assessing the effects of health communication at a neural level. PMID:28402568
Full Text Available Over half of the Australian population does not meet physical activity guidelines and has an increased risk of chronic disease. Web-based physical activity interventions have the potential to reach large numbers of the population at low cost, however issues have been identified with usage and participant retention. Personalised (computer-tailored physical activity advice delivered through video has the potential to address low engagement, however it is unclear whether it is more effective in engaging participants when compared to text-delivered personalised advice. This study compared the attention and recall outcomes of tailored physical activity advice in video- versus text-format. Participants (n=41 were randomly assigned to receive either video- or text-tailored feedback with identical content. Outcome measures included attention to the feedback, measured through advanced eye-tracking technology (Tobii 120, and recall of the advice, measured through a post intervention interview. Between group ANOVA’s, Mann-Whitney U tests and Chi square analyses were applied. Participants in the video-group displayed greater attention to the physical activity feedback in terms of gaze-duration on the feedback (7.7 min vs. 3.6 min, p< 001, total fixation-duration on the feedback (6.0 min vs. 3.3 min, p< 001, and focusing on feedback (6.8 vs. 3.5 min, p< 001. Despite both groups having the same ability to navigate through the feedback, the video-group completed a significantly (p< .001 higher percentage of feedback sections (95% compared to the text-group (66%. The main messages were recalled in both groups, but many details were forgotten. No significant between group differences were found for message recall. These results suggest that video-tailored feedback leads to greater attention compared to text-tailored feedback. More research is needed to determine how message recall can be improved, and whether video-tailored advice can lead to greater health

Background Sources of sexual health information exert strong influence on adolescents’ sexual behavior. Purpose The current study was undertaken to understand how family serve as sexual information sources, the messages adolescents recall from family, and how family learning experiences affect sexual behavior among at-risk adolescents. Methods Individual interviews were conducted with 69 teens, ages 15–18 years, from an alternative high school and a juvenile correctional facility to capture adolescents’ early sexual health learning experiences involving family and evaluate their association with teens’ recent sexual behavior. Sexual learning narratives were compared among gender and sexual experience groups. Results Many participants identified family as sexual health information sources. Primary messages recalled: risks of sex, protection, and relationship advice. Many adolescents portrayed learning experiences as negative, cautionary, lacking detail and not always balanced with positive messages. Participants who reported four or more sexual risks were the only group to identify pornography as a sexual health information source. Participants who reported fewer than four sexual risks were most likely to identify family sexual health information sources. Discussion Participants identified family members as sources of sexual health information, with variations by gender. Negative/cautionary messages require teens to seek additional sexual information elsewhere (primarily friends/media). Males, in particular, appear to often lack familial guidance/education. Translation to Health Education Practice Sexual health messages should be tailored to adolescents’ needs for practical and sex-positive guidance regarding mechanics of sex and formation of healthy relationships, and balanced with cautions regarding negative consequences.

Filipino illustrated magazines, or the comics, may yet prove to be the most effective media, if not the most effective, for spreading the country's development messages. Long criticized by intellectuals and the social elite, the comics have been grossly underrated in their potential to inform, persuade, and even influence the life-style of the people. The government's Commission on Population (Popcom) has developed an information-education-communication program using the comics, among other media, to disseminate stories on family planning, responsible parenthood, and related topics. Its best quality is popular appeal, and for publishers and distribution outlets, the comics provide good business. A review of these materials shows that their themes reflect the following topics or issues: 1) population trends and consequences; 2) socioeconomic benefits of family planning; 3) customs which influence family planning; 4) family planning concepts; 5) family planning methods; 6) human sexuality and reproduction; 7) the husband-wife relationship; 8) guides for family planning motivation or communication; and 9) guides for teaching family planning. The materials were developed with 4 qualities in mind so as to attract audience or reader interest: simplicity, familiarity, realism, and attractiveness of materials. The consensus is that in the comics, population and development agencies may have found a "secret weapon" in getting these messages across, and that this new-found use for the illustrated magazines may be giving them a new respectability without in any way diminishing their popular appeal.

Public administration organizations commonly produce citizen-focused, informational materials describing public programs and the conditions under which citizens or citizen groups are eligible for these programs. The organizations write these materials for generic audiences because of the excessive human resource costs that would be required to produce personalized materials for everyone. Unfortunately, generic materials tend to be longer and harder to understand than materials tailored for particular citizens. Our work explores the feasibility and effectiveness of automatically producing tailored materials. We have developed an adaptive hypermedia application system that automatically produces tailored informational materials and have evaluated it in a series of studies. The studies demonstrate that: (1) subjects prefer tailored materials over generic materials, even if the tailoring requires answering a set of demographic questions first; (2) tailored materials are more effective at supporting subjects in their task of learning about public programs; and (3) the time required to specify the demographic information on which the tailoring is based does not significantly slow down the subjects in their information seeking task.

Along with the development of technology today, humans are very facilitated in accessing information and Communicate with various media, including through the Internet network . Messages are sent by media such as text are not necessarily guaranteed security. it is often found someone that wants to send a secret message to the recipient, but the messages can be known by irresponsible people. So the sender feels dissappointed because the secret message that should be known only to the recipient only becomes known by the irresponsible people .

Evidence linking both active smoking and secondhand smoke exposure to premenopausal breast cancer makes the development of health messages specific to younger women a pressing priority. To determine how to communicate information about this modifiable breast cancer risk to young women, we analyzed a selection of 32 recent English-language breast cancer messages and campaigns that targeted young women. In addition, we obtained young women's responses to three breast cancer campaign images during focus group discussions. A visual analysis of messages points to an explicitly gendered discourse within contemporary campaigns, one that entails conflicting messages regarding breast cancer, health, feminine beauty, and risk. Although the intent might be to educate and empower young women to "fight" against breast cancer, paradoxically, the messages employ imagery that sexually objectifies young women's breasts and bodies. Recommendations are made for messaging about tobacco and breast cancer risk to avoid reproducing one-dimensional or stereotypical presentations of gender and femininity.

The Centers for Disease Control and Prevention ranks colorectal cancer (CRC) as the third most commonly diagnosed cancer among men in the United States; African American (AA) men are at even greater risk. The present study was from a larger study that investigates the church's role as a social marketer of CRC risk and prevention messages, and whether religiously targeted and tailored health promotion materials will influence screening outcome. We used an integrated theoretical approach to explore participants' perceptions of CRC risk and prevention and how promotion messages should be developed and socially marketed by the church. Six focus groups were conducted with men from predominately AA churches in the Midwest. Themes from focus group discussions showed participants lacked knowledge about CRC, feared cancer diagnosis, and feared the procedure for screening. Roles of masculinity and the mistrust of physicians were also emergent themes. Participants did perceive the church as a trusted marketer of CRC but believed that promotional materials should be cosponsored and codeveloped by reputable health organizations. Employing the church as a social marketer of CRC screening promotion materials may be useful in guiding health promotions and addressing barriers that are distinct among African American men. © 2015 Society for Public Health Education.

Contemporary research on attitude change processes is reviewed for implications regarding the relative influence of successive opposing messages on final judgements. Based on this review, extent of message relevant elaboration is offered as a moderator of primacy versus recency effects in prior research. Support for this view is derived from the ability to explain the results of pervious studies and from two experiments in which message presentation order and personal relevance of the topic a...

The principal theme of the dissertation research was determining the relation between aerogel electrode morphology and electrochemical performance. Issues such as electrical wiring and mass transport in transition metal oxide, aerogel electrodes were addressed and designs were tailored for electrochemical applications. Single-wall carbon nanotubes were used to form the electronically conducting network in lithium intercalation electrodes that incorporated vanadium oxide aerogel as the active material. The similarities in morphology and dimensional scale for the nanotubes and V2O5 ribbons enabled excellent electrical contact to be made between the two phases without seriously affecting the aerogel nanostructure. The electrodes exhibited specific capacities in excess of 400 mAh/g at high discharge rates and retained this level of capacity on cycling. A second research goal was to improve mass transport within the aerogel electrode by minimizing tortuosity. In this research, hierarchically ordered vanadium oxide aerogel electrodes were designed and fabricated. The electrodes have two discrete and independent levels or porosity. At one level, ordered, interconnected macropores were fabricated using the templating process. At another level, interconnected mesopores were created using sol-gel synthesis and ambient drying. Electrochemical activity towards lithium was demonstrated using cyclic voltammetry and chronopotentiometry. These data are believed to be the first to demonstrate electrochemical activity for the class of materials based on the inverse opal structure. Several Group I cations and multivalent cations were reversibly, and electrochemically reacted with vanadium oxide aerogel. The molar capacities of the Group I elements (Na+ = 3.0 moles and K+ = 2.0) were high and comparable to Li+ (3.6 moles). Interestingly, the electron equivalent capacity for Mg2+ (4.0) was higher than Li+ and agrees well with the chemical titration capacity. Galvanostatic rate

Many studies assess provider-patient communication through text messaging; however, minimal research has addressed communication among physicians. The purpose of this study was to evaluate the use of text messaging by pediatric hospitalists. A brief, anonymous, electronic survey was distributed through the American Academy of Pediatrics Section on Hospital Medicine Listserv in February 2012. Survey questions assessed work-related text messaging. Of the 106 pediatric hospitalist respondents, 97 met inclusion criteria. Most were female (73%) and had been in practice work-life balance. Future research should examine accuracy and effectiveness of text message communication in the hospital, as well as patient privacy issues.

Social media platforms are increasingly used to disseminate social marketing messages about mental health and wellbeing. This study presents a range of message appeals used in social media enabled mental health promotion and stigma reduction messages. Furthermore, it examines the relationship between the type of message appeals and audience engagement. A content analysis of 65 organisation-generated YouTube videos about depression and anxiety and stigma reduction was conducted. The most utilised message appeal was Sorrow, followed by Affiliation, Ease/Convenience, Hope, Humour, Guilt/Shame, Heroic/Successful, and Fear. Multiple regression analysis was used to examine the relationship between the type of message appeals and audience engagement in terms of the number of likes, comments, and shares. The analysis revealed that Sorrow is the most useful message appeal for generating audience comments. However, Sorrow is negatively associated with the number of likes and shares. The results suggest that mental health promotion messages may engage a larger audience through Affiliation and Hope as they have a positive impact on the number of shares. This could, in effect, turn audiences into vocal advocates for mental health promotion and stigma reduction messages. © The Author 2017. Published by Oxford University Press. All rights reserved.

Full Text Available Architecture conceived as the superposition of historic contributions and safeguard of the traces and fragments of memory has a unique, irreproducible character in its matter and messages that must be respected by the architect. Now that the concept of restoration as functional, mechanical or typological repairs to the building and the need to correct, amend or formally improve the monument from a contemporary viewpoint has been transcended and a really respectful symbiosis of contemporary methodology has been achieved, the time has come for a sensitive approach, half-way between reason and sentiment, making it possible to minimise the impact of the restoration works on the character and sensitive experience of architecture.

Hispanic adults in the United States are at particular risk for diabetes and inadequate blood pressure control. Physical activity improves these health problems; however Hispanic adults also have a low rate of recommended aerobic physical activity. To address improving physical inactivity, one area of rapidly growing technology that can be utilized is text messaging (short message service, SMS). A physical activity research team, Text4Walking, had previously developed an initial database of motivational physical activity text messages in English that could be used for physical activity text messaging interventions. However, the team needed to translate these existing English physical activity text messages into Spanish in order to have culturally meaningful and useful text messages for those adults within the Hispanic population who would prefer to receive text messages in Spanish. The aim of this study was to translate a database of English motivational physical activity messages into Spanish and review these text messages with a group of Spanish speaking adults to inform the use of these text messages in an intervention study. The consent form and study documents, including the existing English physical activity text messages, were translated from English into Spanish, and received translation certification as well as Institutional Review Board approval. The translated text messages were placed into PowerPoint, accompanied by a set of culturally appropriate photos depicting barriers to walking, as well as walking scenarios. At the focus group, eligibility criteria for this study included being an adult between 30 to 65 years old who spoke Spanish as their primary language. After a general group introduction, participants were placed into smaller groups of two or three. Each small group was asked to review a segment of the translated text messages for accuracy and meaningfulness. After the break out, the group was brought back together to review the text messages

Worldwide, there has been a startling increase in the number of people who are obese or overweight. Obesity increases the risk of cardiovascular disease and overall mortality. Mobile phone messaging is an important means of human communication globally. Because the mobile phone can be used anywhere at any time, mobile phone messaging has the potential to manage obesity. We investigated the effectiveness of a one-way text messaging intervention for obesity. Participants' body mass index and waist circumference were measured at the beginning of the programme and again after 12 weeks. The text message group received text messages about exercise, dietary intake, and general information about obesity three times a week, while the control group did not receive any text messages from the study. Of the 80 participants, 25 subjects in the text message group and 29 participants in the control group completed the study. After adjusting for baseline body mass index, the body mass index was significantly lower in the text message group than in the control group (27.9 vs. 28.3; p = 0.02). After adjusting for the baseline waist circumference, the difference of waist circumference between the text message group and control group was not significant (93.4 vs. 94.6; p = 0.13). The one-way text messaging intervention was a simple and effective way to manage obesity. The one-way text messaging intervention may be a useful method for lifestyle modification in obese subjects. © The Author(s) 2015.
Full Text Available Through a participatory action research study, this study identifies and analyses the associations and symbols attached by adolescents at school age in target schools, identifies strategies and message appeals based on the associations and embedded symbols so that it is appropriately used for preventive efforts of smoking behaviours and. Based on the results of the study can be concluded that there are two perspectives in associating cigarettes, first is the symbol of masculinity and flexibility in associating, the second is associated with opium, and poison. Further intervention can be done by presenting humour based appeals at the group level and rational based message appeals at the individual level. In the context of health communication, this research has shown how Social Cognitive Theory is used in the study of promotion of health by emphasising the design of fear-based appeals.

Reablement is an interprofessional, home-based rehabilitation service that aims to enable senior residents to cope with everyday life and to prevent functional impairments. Systematic accounts of what practitioners actually do when establishing reablement are lacking. This study aims to generate a grounded theory of practitioners' patterns of action when establishing reablement. The study is located in Norway, and grounded theory is the methodological approach. Data were collected from January 2014 to August 2016 through participant observations, focus group interviews and individual interviews. Informants are municipal healthcare employees in different organisational areas associated with the process of establishing reablement services (managers of conventional home care and representatives from the administration and service-provider offices). Altogether, 17 individuals are interviewed. The empirical data are analysed several times using open, selective and theoretical coding. The grounded theory, "tailoring reablement," includes three phases-replicating, adapting and establishing-and the strategies of collaborating, developing knowledge, habituating and filtering. The theory of tailoring reablement also includes the impact of the contextual factors. The study seeks to bridge the gap between research and practice. The theory of tailoring reablement emerges from an inductive approach and theorises participants' actions. The theory focuses on the phases from innovation to implementation. Establishing a new service model in a complex welfare setting requires a wide range of actors and agencies. Tailoring reablement also requires flexibility and professional autonomy. It is important to create terms and conditions for this within a stringent health and care service. The insights of this study have implications for practice development of reablement and can fit other public sector fields. © 2017 The Authors.

Using Gray and McNaughton's (2000) revised reinforcement sensitivity theory (r-RST), we examined the influence of personality on processing of words presented in gain-framed and loss-framed anti-speeding messages and how the processing biases associated with personality influenced message acceptance. The r-RST predicts that the nervous system regulates personality and that behaviour is dependent upon the activation of the behavioural activation system (BAS), activated by reward cues and the fight-flight-freeze system (FFFS), activated by punishment cues. According to r-RST, individuals differ in the sensitivities of their BAS and FFFS (i.e., weak to strong), which in turn leads to stable patterns of behaviour in the presence of rewards and punishments, respectively. It was hypothesised that individual differences in personality (i.e., strength of the BAS and the FFFS) would influence the degree of both message processing (as measured by reaction time to previously viewed message words) and message acceptance (measured three ways by perceived message effectiveness, behavioural intentions, and attitudes). Specifically, it was anticipated that, individuals with a stronger BAS would process the words presented in the gain-frame messages faster than those with a weaker BAS and individuals with a stronger FFFS would process the words presented in the loss-frame messages faster than those with a weaker FFFS. Further, it was expected that greater processing (faster reaction times) would be associated with greater acceptance for that message. Driver licence holding students (N=108) were recruited to view one of four anti-speeding messages (i.e., social gain-frame, social loss-frame, physical gain-frame, and physical loss-frame). A computerised lexical decision task assessed participants' subsequent reaction times to message words, as an indicator of the extent of processing of the previously viewed message. Self-report measures assessed personality and the three message

Hospitals today are experiencing major changes in their clinical communication workflows as conventional numeric paging and face-to-face verbal conversations are being replaced by computer mediated communication systems. In this paper, we highlight the importance of understanding this transition and discuss some of the impacts that may emerge when verbal clinical conversations are replaced by short text messages. In-depth interviews (n=108) and non-participatory observation sessions (n=260h) were conducted on the General Internal Medicine wards at five academic teaching hospitals in Toronto, Canada. From our analysis of the qualitative data, we identified two major themes. De-contextualization of complex issues led to an increase in misinterpretation and an increase in back and forth messaging for clarification. Depersonalization of communication was due to less verbal conversations and face-to-face interactions and led to a negative impact on work relationships. Text-based communication in hospital settings led to the oversimplification of messages and the depersonalization of communication. It is important to recognize and understand these unintended consequences of new technology to avoid the negative impacts to patient care and work relationships.

The ubiquity of cell phones, which allow for short message service (SMS), provides new and innovative opportunities for disease prevention and health education. To explore the use of cell phone-based health education SMS to improve the health literacy of community residents in China. A multi-stage random sampling method was used to select representative study communities and participants ≥ 18 years old. Intervention participants were sent health education SMSs once a week for 1 year and controls were sent conventional, basic health education measures. Health literacy levels of the residents before and after the intervention were evaluated between intervention and control groups. Public health literacy scores increased 1.5 points, from 61.8 to 63.3, after SMS intervention for 1 year (P<0.01); the increase was greater for males than females (2.01 vs. 1.03; P<0.01) and for Shenzhen local residents than non-permanent residents (2.56 vs. 1.14; P<0.01). The frequency of high health literacy scores was greater for the intervention than control group (22.03% to 30.93% vs. 22.07% to 20.82%). With health literacy as a cost-effective index, the cost-effectiveness per intervention was 0.54. SMS may be a useful tool for improving health literacy.

In gastroenterology a sufficient colon cleansing improves adenoma detection rate and prevents the need for preterm repeat colonoscopies due to invalid preparation. It has been shown that patient education is of major importance for improvement of colon cleansing. Objective of this study was to assess the function of an automated text messaging (short message service, SMS)-supported colonoscopy preparation starting 4 days before colonoscopy appointment. After preevaluation to assess mobile phone usage in the patient population for relevance of this approach, a Web-based, automated SMS text messaging system was developed, following which a single-center feasibility study at a tertiary care center was performed. Patients scheduled for outpatient colonoscopy were invited to participate. Patients enrolled in the study group received automated information about dietary recommendations and bowel cleansing during colonoscopy preparation. Data of outpatient colonoscopies with regular preparation procedure were used for pair matching and served as control. Primary end point was feasibility of SMS text messaging support in colonoscopy preparation assessed as stable and satisfactory function of the system. Secondary end points were quality of bowel preparation according to the Boston Bowel Preparation Scale (BBPS) and patient satisfaction with SMS text messaging-provided information assessed by a questionnaire. Web-based SMS text messaging-supported colonoscopy preparation was successful and feasible in 19 of 20 patients. Mean (standard error of the mean, SEM) total BBPS score was slightly higher in the SMS group than in the control group (7.3, SEM 0.3 vs 6.4, SEM 0.2) and for each colonic region (left, transverse, and right colon). Patient satisfaction regarding SMS text messaging-based information was high. Using SMS for colonoscopy preparation with 4 days' guidance including dietary recommendation is a new approach to improve colonoscopy preparation. Quality of colonoscopy

Normative messages have been shown to increase intention to do physical activity. We traced how "positive" and "negative" normative messages influenced physical activity intention by comparing constructs of the model of goal-directed behavior with descriptive norms (MGDB + DNs) across control and treatment groups in an experiment. For this purpose, 16-24-year-old respondents (n = 1,200) in Bulgaria, Croatia, and Romania were asked about their age, sex, and levels of physical activity before being exposed to positive and negative normative messages and completing a questionnaire with MGDB + DNs scales. Different MGDB + DNs constructs were influenced by the normative messages: compared with the control, the negative message group showed stronger attitudes (p = .003) and the positive message group showed higher positive anticipated emotions (p = .005). The positive message's effect is consistent with the literature on conformity to social norms. The negative message's effect lends itself to interpretations based on social identity and deviance regulation theories.
