Promoting the use of contact tracing technology will be an important step in global recovery from the COVID-19 pandemic. Across two studies, we assessed two messaging strategies as motivators of intended contact tracing uptake. In one sample of 1117 Australian adults and one sample of 888 American adults, we examined autonomy-supportive and controlling message framing and the presence or absence of information safety as predictors of intended contact tracing application uptake, using an online randomized 2 × 2 experimental design. (...) The results suggested that the provision of data safety assurances may be key in affecting people’s intentions to use contact tracing technology, an effect we found in both samples regardless of whether messages were framed as autonomy-supportive or controlling. Those in high information safety conditions consistently reported higher intended uptake and more positive perceptions of the application than those in low information safety conditions. In Study 2, we also found that perceptions of government legitimacy related positively to intended application uptake, as did political affiliation. In sum, individuals appeared more willing to assent to authority regarding contact tracing insofar as their data safety can be assured. Yet, public messaging strategies alone may be insufficient to initiate intentions to change behavior, even in these unprecedented circumstances. (shrink)

Health promotion messages that evoke fear are often used to decrease unrealistic optimism regarding risks, convince people to control their behaviour, and make risks memorable. The relations among emotions, risk and control judgements, and memory are not well understood, however. In the current study, participants (N = 94) were assigned to fearful, angry, happy, or neutral emotion-elicitation conditions. They then rated the likelihood of experiencing 15 negative and 15 positive matched outcomes and rated their degree of control (...) over each outcome. A surprise memory test followed. Fear decreased unrealistic optimism, but the greater the intensity of fear reported the less control participants believed they had over outcomes. Fear also led to poorer memory for outcomes. Across all participants, the lower their ratings of optimism and control concerning outcomes, the less likely they were to recall them. Implications for the use of emotionally evocative material in health promotion messages are discussed. (shrink)

The Joint Battle Management Language (JBML) is an XML-based language designed to allow Command and Control (C2) systems to interface easily with Modeling and Simulation (M&S) systems. While some of the XML-tags defined in this language correspond to types of entities that exist in reality, others are mere syntactic artifacts used to structure the messages themselves. Because these two kinds of tags are not formally distinguishable, JBML messages in effect confuse data with what the data represent. In this paper (...) we show how a realism-based ontology combined with a rule language can be used to make these distinctions explicit. The approach allows storage of the contents of JBML messages in a Referent Tracking System in a format that mimics the structure of reality thereby providing an aid to message validation. (shrink)

The HealthyFood program offers members up to 25% cash back monthly on healthy food purchases. In this randomized controlled trial, we tested the efficacy of financial incentives combined with text messages in increasing healthy food purchases among HF members. Members receiving the lowest cash back level were randomized to one of six arms: Arm 1 : 10% cash back, no weekly text, standard monthly text; Arm 2: 10% cash back, generic weekly text, standard monthly text; Arm 3: 10% cash back, (...) personalized weekly text, standard monthly text; Arm 4: 25% cash back, personalized weekly text, standard monthly text; Arm 5: 10 + 15%NET cash back, personalized weekly text, standard monthly text; and, Arm 6: 10 + 15%NET cash back, personalized weekly text, unbundled monthly text. In the 10 + 15%NET cash back, the cash back amount was the baseline 10% plus 15% of the net difference between healthy and unhealthy spending. The generic text included information on HF and healthy eating, while the personalized text had individualized feedback on purchases. The standard monthly text contained the cash back amount. The unbundled monthly text included the amount lost due to unhealthy purchases. The primary outcome was the average monthly percent healthy food spending. Secondary outcomes were the percent unhealthy food spending, and the percent healthy and unhealthy food items. Of the members contacted, 20 opted out, and 2841 met all inclusion criteria. There were no between-arm differences in the examined outcomes. The largest mean difference in percent healthy spending was between Arm 1 and Arm 2, and the largest mean difference in percent unhealthy spending was also between Arm 1 and Arm 2, but no differences were statistically significant after correction for multiple comparisons. None of the tested financial incentive structures or text strategies differentially affected food purchasing. Notably, more than doubling the cash back amount and introducing a financial disincentive for unhealthy purchases did not affect purchasing. These findings speak to the difficulty of changing shopping habits and to the need for innovative strategies to shift complex health behaviors.

Although the study of the affective components involved in predicting physical activity is spreading faster and faster, there is a lack of studies testing their role when promoting physical activity through message interventions. In the present study, we considered these components by focusing on how anticipated affective reactions and emotional processing of the messages influence receivers’ affective attitude toward physical activity, concurrent behavior, and future intention. A sample of 250 participants was involved in an intervention relying on prefactual messages (...) promoting physical activity. All messages were sent through a research app and were focused on the expected consequences of exercising. Four experimental conditions involving messages differing as to their outcome sensitivity framing were compared to a control condition. Results showed that reading gain and non-gain messages enhanced the positive affective attitude toward physical activity, compared to control. Enhanced affective attitude after the intervention increased, in turn, self-reported physical activity and future intention. Interestingly, gain messages were even more persuasive for people with a low level of positive anticipated affective reactions. Furthermore, their effectiveness was especially attributable to the elicitation of hope in receivers. Discussion focuses on the advantages of considering affective components and their implications when promoting physical activity. (shrink)

BackgroundIn crisis communication, warning messages are key to informing and galvanizing the public to prevent or mitigate damage. Therefore, this study examines how risk appraisal and individual characteristics influence the intention to comply with behavioral recommendations of a warning message regarding three hazard types: the COVID-19 pandemic, violent acts, and severe weather.MethodsA cross-sectional survey examined 403 German participants from 18 to 89 years. Participants were allocated to one of three hazard types and presented with warning messages that were previously (...) issued via an official warning app. Four components of risk appraisal—perceived severity, anticipated negative emotions, anticipatory worry, and risk perception —were assessed before and after presenting the warning message. Path models were calculated to predict the intention to comply with the warning message, controlling for age, gender, and previous hazard experience.ResultsFor the COVID-19 pandemic, higher age predicted warning compliance. AE predicted compliance in the case of violent acts. For severe weather, PS, age, and female gender lead to higher compliance. Changes across risk appraisal components were not consistent, as some facets decreased after the receipt of a warning message.DiscussionRisk appraisal has shown a marginal yet differential influence on warning message compliance in different types of hazards. Regarding the COVID-19 pandemic, the impact of sociodemographic factors on compliance should be studied more intensively. Moreover, integrating intermediary variables, such as self-efficacy, is necessary. (shrink)

This research responds to urgent calls to fill knowledge gaps on COVID-19 in communicating social distancing messages to the public in the most convincing ways. The authors explore the effectiveness of framing social distancing messages around prosocial vs. self-interested appeals in driving message compliance and helping behavior. The results show that when a message emphasizes benefits for everyone in society, rather than solely for the individual, citizens find the message more persuasive to engage in social distancing, and (...) also more motivating to help others. The results further demonstrate that the proposed effects are higher for individuals who have a lower locus of control and lower fear of coronavirus as prosocial messages lead them to feel a joint responsibility in protecting from the pandemic. Theoretical and practical implications of the results are discussed. (shrink)

On March 16, 2020, the Director-General of the World Health Organization said: “We have a simple message to all countries—test, test, test.” This seems like sound advice, but what if limiting the number of tests has a positive effect on infection control? Although this may rarely be the case, the possibility raises an important ethical question that is closely related to a central tension between deontological and consequentialist approaches to ethics. In this paper, we first argue that early (...) during the COVID-19 pandemic, Japan offers an interesting case because it experienced few deaths due to COVID while the number of tests was limited, suggesting that there may be cases in which low testing contributes to infection control indeed. After that, we examine deontological constraints on such a “low-testing” policy, focusing on issues related to a supposed “right to know,” which is a central issue in medical ethics in general.

How do adolescent girls envision the world of work and their potential place in it? This article considers teen magazines as a possible source for girls’ perceptions about the work world, including their own career futures. The author explores the occupational landscape embedded with in Seventeen magazinein 1992 in both quantitative and qualitative terms. The labor market in Seventeen-land is heavily skewed toward professional occupations, particularly in the entertainment industry. A close reading of the text reveals four primary messages about (...) the world of work: Entertainment careers are a viable and prestigious option, men are the norm as workers, men hold the power, and fashion modeling is the pinnacle of “women’s work. ” The author argues that Seventeen may be promulgating a distinct set of what Collins called “controlling images” directed at predominantly white girls. The findings suggest gender researchers should attend to the connection between the mass media and girl culture. They also underscore the importance of teaching media literacy. (shrink)

Believing in free will may arise from a biological need for control. People induced to disbelieve in free will show impulsive and antisocial tendencies, suggesting a reduction of the willingness to exert self-control. We investigated whether undermining free will affects two aspects of self-control: intentional inhibition and perceived self-control. We exposed participants either to anti-free will or to neutral messages. The two groups then performed a task that required self-control to inhibit a prepotent response. No-free (...) will participants showed less intentional inhibitions than controls, suggesting a reduction of self-control. We assessed perceived self-control by asking participants whether the response resulted from a deliberate intention or from an impulsive reaction. Perceived self-control was lower in the no-free will group than in control group. Our findings show that undermining free will can degrade self-control and provide insights into how disbelieving in free will leads to antisocial tendencies. (shrink)

This paper has arisen directly from the authors’ experiences of leading professional development for teachers in Philosophy with Children (P4C), a well-established approach to teaching that seeks to foster philosophical questioning, critical thinking, reasoning and dialogue. The paper expresses deep concern about the anxiety shown by many teachers regarding discussion of controversial issues in the classroom, and some teachers’ avoidance of open-ended dialogue about works of children’s literature that might touch on taboo subjects. The authors suggest that this is indicative (...) of a desire for risk-free teaching and is a form of censorship that marginalises children and limits their learning and academic freedom. The exercise of such avoidance and control reduces the potential for schools to become more democratic institutions. Drawing directly on their practice of working philosophically with children in school, as well as on philosophical and other sources, the authors of the paper offer a range of arguments about the processes of education to support the case for challenging such forms of censorship and risk avoidance.

In an era of rising social awareness, both academics and practitioners have been concerned about the effectiveness of pro-social consumer influence strategies. The main assumption here is that for social marketing to succeed one must first understand the factors underlying pro-social consumer behavior. Firstly, drawing on two dimensions the authors first identify four types of social behavior. Next, the model describes social behavior as a result of preceding social behavior motivation and actual social behavior intention. Norms and economic evaluation have (...) an impact on social behavior motivation, which in turn influences social behavior intention, eventually leading to actual social behavior. Actual control factors, such as the availability of resources and opportunities, decide whether social behavior intention can really translate into actual social behavior. Finally, authors propose message strategies for each type of social behavior. (shrink)

There is evidence from neuropsychological and psychophysical measurements that conscious sensory information is processed in discrete time segments. The segmentation process may be described as neuronal activity at a frequency of 40 Hz. Stimulus-induced neuronal activities of this frequency are found in the middle latency range of the auditory evoked potential . First, we have studied the effects of different general anesthetics on MLAEP and auditory evoked 40-Hz activity. Second, we investigated MLAEP and explicit and implicit memory for information presented (...) during cardiac anesthesia. In the awake patients peak latencies of the MLAEP were in the normal range. An auditory evoked 40-Hz activity was present 20–100 ms poststimulus. Under nonspecific anesthetics MLAEP and the 40-Hz activity were suppressed, and under receptor-specific agents MLAEP and the 40-Hz activity were partly preserved. None of the cardiac patients had conscious explicit recall of the intraoperative events, whereas some patients showed unconscious implicit memory for an intraoperative tape message. The implicit memory could be related to midlatency auditory evoked potentials. No implicit memory was detectable when MLAEP and the primary cortical processing of the auditory stimuli and 40-Hz activity were blocked. Implicit memory could be detected in more than 50% of the cases when MLAEP, a 30-Hz activity, and the primary cortical stimulus processing were preserved. In conclusion, our observations support the view that a high frequency oscillatory mechanisms, recorded as a grouped neuronal activity in the MLAEP, may be part of a basic neuronal program for conscious sensory information processing.

Almost all messenger RNAs carry a polyadenylate tail that is added in a post‐transcriptional reaction. In the nuclei of animal cells, the 3'‐end of the RNA is formed by endonucleolytic cleavage of the primary transcript at the site of poly (A) addition, followed by the polymerisation of the tail. The reaction depends on specific RNA sequences upstream as well as downstream of the polyadenylation site. Cleavage and polyadenylation can be uncoupled in vitro. Polyadenylation is carried out by poly(A) polymerase with (...) the aid of a specificity factor that binds the polyadenylation signal AAUAAA. Several aditional factors are required for the initial cleavage. A newly discovered poly(A)‐binding protein stimulates poly(A) tail synthesis and may be involved in the control of tail length. Polyadenylation reactions different from this scheme, either in other organisms or under special physiological circumstances, are discussed. (shrink)

This study investigates how patterns of media use and exposure to media messages are related to attitudes about artificial intelligence (AI) image generators. In doing so, it builds on theoretical accounts of media framing and public opinion about science and technology topics, including AI. The analyses draw on data from a survey of the US public (N = 1,035) that included an experimental manipulation of exposure to tweets framing AI image generators in terms of real art, artists’ concerns, artists’ outrage, (...) or competing interpretations. The results show that technology news use and science fiction viewing predicted support for AI art but also predicted belief that AI image generators will take jobs and steal art styles from human artists. In addition, the experimental results demonstrate that exposure to specific media messages can influence these responses. The findings carry implications for understanding the future adoption, use, and regulation of AI image generators. (shrink)

Terrorism researchers have long discussed the role of psychology in the radicalization process. This work has included research on the respective roles of individual psychological traits and responses to terrorist propaganda. Unfortunately, much of this work has looked at psychological traits and responses to propaganda individually and has not considered how these factors may interact. This study redresses this gap in the literature. In this experiment (N = 268), participants were measured in terms of their narcissism, Machiavellianism, subclinical psychopathy, and (...) everyday sadism—collectively called the Dark Tetrad. Participants were then exposed to a vivid or nonvivid terrorist narrative (or a control message). Results indicate that Machiavellianism interacts with both narrative exposure and narrative vividness to amplify the persuasive effect of terrorist narratives. Neither narcissism, subclinical psychopathy, nor everyday sadism had such an effect. These results highlight the importance of considering the psychological traits of audiences when evaluating proclivity for radicalizationviapersuasion by terrorist narratives. (shrink)

Digital piracy is costly to creative economies across the world. Studies indicate that anti-piracy messages can cause people to pirate more rather than less, suggesting the presence of psychological reactance. A gender gap in piracy behavior and attitudes towards piracy has been reported in the literature. By contrast, gender differences in message reactance and the moderating impact of attitudes have not been explored. This paper uses evolutionary psychology as a theoretical framework to examine whether messages based on real-world anti-piracy (...) campaigns cause reactance and whether this effect is explained by gender and pre-existing attitudes. An experiment compares one prosocial and two threatening messages against a control group to analyze changes in piracy intention from past behavior for digital TV/film. Results indicate that the prosocial message has no significant effect, whereas the threatening messages have significantly opposing effects on men and women. One threatening message influences women to reduce their piracy intentions by over 50% and men to increase it by 18%. We find that gender effects are moderated by pre-existing attitudes, as men and women who report the most favorable attitudes towards piracy tend to demonstrate the most polarized changes in piracy intentions. The practical implications of the results are that men and women process threatening messages differently, therefore behavioral change messages should be carefully targeted to each gender. Explicitly, threatening messages may be effective on women, but may have the reverse effect on men with strong favorable attitudes towards the target behavior. (shrink)

We present results from a study about women and employee-elected board members, and fill some of the gaps in the literature about their contribution to board effectiveness. The empirical data are from a unique data set of Norwegian firms. Board effectiveness is evaluated in relation to board control tasks, including board corporate social responsibility (CSR) involvement. We found that the contributions of women and employee-elected board members varied depending on the board tasks studied. In the article we also explored (...) the effects of the esteem of the women and employee-elected board members, and we used creative discussions in the boardroom as a mediating variable. Previous board research, including research about women and employee-elected directors, questions if the board members contribute to board effectiveness. The main message from this study is that it may be more important to ask how, rather than if, women and employee-elected board members contribute, and we need to open the black box of actual board behavior to explore how they may contribute.

Structurally, microtubules (MTs) are composed of protofilaments of the subunit protein. They are prominent components of the cytoplasmic matrix and perform important functions as cytoskeletal elements for the determination of cell shape and as key elements in intracellular motility such as mitosis and the translocation of cell organelles. These functions are thought to depend on the controlled assembly and disassembly of MTs in the cytoplasm and on the interaction of MTs with each other and with other cytoplasmic components. I think (...) that apart from these cellular functions, MTs have the function of message transmission. Although no direct evidence is available to explain this point at present, a number of inddirect evidences have been obtained by many scientists e.g.: brain tissue has circumstantial the highest tubulin concentration, MTs have the property of self-assembly and disassembly, microtubule(MT) network is a key factor in differentiation of plant cells.

Adolescents, as active online searchers, have easy access to health information. Much health information they encounter online is of poor quality and even contains potentially harmful health information. The ability to identify the quality of health messages disseminated via online technologies is needed in terms of health attitudes and behaviors. This study aims to understand how different ways of editing health-related messages affect their credibility among adolescents and what impact this may have on the content or format of health information. (...) The sample consisted of 300 secondary school students. To examine the effects of manipulating editorial elements, we used seven short messages about the health-promoting effects of different fruits and vegetables. Participants were then asked to rate the message’s trustworthiness with a single question. We calculated second-order variable sensitivity as the derivative of the trustworthiness of a fake message from the trustworthiness of a true neutral message. We also controlled for participants’ scientific reasoning, cognitive reflection, and media literacy. Adolescents were able to distinguish overtly fake health messages from true health messages. True messages with and without editorial elements were perceived as equally trustworthy, except for news with clickbait headlines, which were less trustworthy than other true messages. The results were also the same when scientific reasoning, analytical reasoning, and media literacy were considered. Adolescents should be well trained to recognize online health messages with editorial elements characteristic of low-quality content. They should also be trained on how to evaluate these messages.

Recalling the title of Yoxen’s classical paper on the influence of Schrödinger’s book, I analyze the role that the work of H. Pattee might have played, if any, in the development of Biosemiotics. I take his 1969 paper “How does a molecule become a message?” (Developmental Biology Supplement) as a first target due to several circumstances that make it especially salient. On the one hand, even if Pattee has obviously developed further his ideas on later papers, the significance of (...) this one springs out right from the title, the journal and date of publication and, of course, its content. On the other, this paper in particular has been somehow rediscovered recently and not only within the frame of biosemiotics (eg, in history and philosophy of biology by E.F. Keller). Following the parallelism with Yoxen’s perspective, I contend that Pattee’s work was relatively influential with respect to a good amount of attempts to rethink living systems within theoretical biology around the 70s. This influence diminished together with the decay or even collapse of those attempts under the impact of molecular biology as it was being developed those years. Eventually, Pattee’s work has been taken up again. Notwithstanding, it is quite clear that Pattee himself was not intending to contribute specifically to Biosemiotics and that he was probably unaware of any such discipline, at least until recently. Then, we should as well ask (as Yoxen wonders with respect to Schrödinger) to which extent Pattee’s influence has been a direct one or rather an indication of the relevance of his ideas and the resonance of his hypotheses with those of biosemiotics. For this task I will sketch a few points of convergence and divergence and examine the work of some authors who either address directly this issue or have contributed significantly to build up the history of Biosemiotics.

Issues related to controlled human infection studies using Schistosoma mansoni (CHI-S) were explored to ensure the ethical and voluntary participation of potential CHI-S volunteers in an endemic setting in Uganda. We invited volunteers from a fishing community and a tertiary education community to guide the development of informed consent procedures. Consultative group discussions were held to modify educational materials on schistosomiasis, vaccines and the CHI-S model and similar discussions were held with a test group. With both groups, a mock consent (...) process was conducted. Fourteen in-depth key informant interviews and three group discussions were held to explore perceptions towards participating in a CHI-S. Most of the participants had not heard of the CHI-S. Willingness to take part depended on understanding the study procedures and the consenting process. Close social networks were key in deciding to take part. The worry of adverse effects was cited as a possible hindrance to taking part. Volunteer time compensation was unclear for a CHI-S. Potential volunteers in these communities are willing to take part in a CHI-S. Community engagement is needed to build trust and time must be taken to share study procedures and ensure understanding of key messages. (shrink)

Messenger RNA is a flexible tool box that plays a key role in the dynamic regulation of gene expression. RNA modifications variegate the message conveyed by the mRNA. Similar to DNA and histone modifications, mRNA modifications are reversible and play a key role in the regulation of molecular events. Our understanding about the landscape of RNA modifications is still rudimentary in contrast to DNA and histone modifications. The major obstacle has been the lack of sensitive detection methods since they (...) are non-editing events. However, with the advent of next-generation sequencing techniques, RNA modifications are being identified precisely at single nucleotide resolution. In recent years, methylation at the N6 position of adenine has gained the attention of RNA biologists. The m6A modification has a set of writers, erasers, and readers. Here, we provide a summary of interesting facts, conflicting findings, and recent advances in the technical and functional aspects of the m6A epitranscriptome. The recent outburst of studies has brought the key role of mRNA N6-methyladenosine modification in post-transcriptional processing steps into the limelight. This review summarizes the current progress and the future prospective of m6A methylome. We addressed the debatable function of m6A modification and related modifiers in tumorigenesis and tumor progression. (shrink)

How can we effectively promote the public’s prevention of coronavirus disease 2019 infection? Jordan et al. found with United States samples that emphasizing either self-interest or collective-interest of prevention behaviors could promote the public’s prevention intention. Moreover, prosocially framed messaging was more effective in motivating prevention intention than self-interested messaging. A dual consideration of both cultural psychology and the literature on personalized matching suggests the findings of Jordan et al. are counterintuitive, because persuasion is most effective when the frame of (...) the message delivered and the recipient of the message are culturally congruent. In order to better understand the potential influence of culture, the current research aimed to replicate and extend Jordan et al. findings in the Japanese context. Specifically, we examined the question whether the relative effectiveness of the prosocial appeal is culturally universal and robust, which types of ‘others’ especially promote prevention intention, and which psychological mechanisms can explain the impact of messaging on prevention intention. In Study 1, we confirmed that self-interested framed, prosocially framed, and the combination of both types of messaging were equally effective in motivating prevention intention. In Study 2, we found that family-framed messaging also had a promoting effect similar to that from self-interested and prosocial appeals. However, the relative advantage of prosocial appeals was not observed. Further, a psychological propensity relevant to sensitivity to social rejection did not moderate the impact of messaging on prevention intention in both studies. These results suggest that since engaging in the infection control itself was regarded as critical by citizens after public awareness of COVID-19 prevention has been sufficiently heightened, for whom we should act might not have mattered. Further, concerns for social rejection might have had less impact on the prevention intentions under these circumstances. These results suggest that the relative advantage of a prosocial appeal might not be either culturally universal or prominent in a collectivistic culture. Instead, they suggest that the advantages of such an appeal depends on the more dynamic influence of COVID-19 infection. (shrink)

Though the formal coherence and empirical utility of Marcello Barbieri’s concept of organic code have been starting to become established, a general conception of how the semantics of organic codes is related to the pragmatics of their use is still missing. Barbieri took a first step towards such a conception by distinguishing three types of semiosis in living systems: manufacturing, signalling, and interpretive semiosis. This paper integrates Barbieri’s distinction into Roman Jakobson’s systematization of possible functions of messages in order to (...) propose a general conception of possible types of semiosis in living systems. As a result, Barbieri’s thesis that manufacturing and signalling semiosis are basic types of semiosis, can be confirmed and completed communication-theoretically. (shrink)

Pancreatic beta cells secrete insulin in response to elevated plasma glucose levels in a Ca2+‐dependent fashion. Released insulin may act on the beta cell itself to promote further insulin synthesis and release. Recent studies by Johnson and Misler,1 Masgrau et al.2 and Mitchell et al.3 provide strong evidence (1) for the existence of intracellular Ca2+ stores sensitive to NAADP, a potent Ca2+‐mobilizing messenger, and (2) that these Ca2+ stores are involved in both glucose‐ and insulin‐mediated signal transduction. NAADP may therefore (...) play an important role in controling secretion of insulin from pancreatic beta cells. BioEssays 25:430–433, 2003. © 2003 Wiley Periodicals, Inc. (shrink)

Social networks are widely used as a fast and ubiquitous information-sharing medium. The mass spread of food rumours has seriously invaded public’s healthy life and impacted food production. It can be argued that the government, companies, and the media have the responsibility to send true anti-rumour messages to reduce panic, and the risks involved in different forms of communication to the public have not been properly assessed. The manuscript develops an empirical analysis model from 683 food anti-rumour cases and 7,967 (...) data of the users with top comments to test the influence of the strength of rumour/anti-rumour on rumour control. Furthermore, dividing the users into three categories, Leaders, Chatters, and General Public, and study the influence of human characteristics on the relationship between the strength of rumour/anti-rumour and rumour control by considering the different human characteristics as moderator variables. The results showed that anti-rumours have a significant positive impact on the control of rumours; the ambiguity of rumours has a significant negative impact on the Positive Comment Index in rumour control. Further, the Leaders increased the overall level of PCI, but negatively adjusted the relationship between evidence and PCI; the Chatters and the General Public reduced the overall level of PCI, and Chatters weakened the relationship between the specific type of anti-rumour form and PCI while the General Public enhanced the relationship between the specific type of anti-rumour form and PCI. In the long run, the role of Leaders needs to be further improved, and the importance of the General Public is growing in the food rumour control process. (shrink)

The purpose of the present two studies was to investigate whether in framing messages that target salient beliefs of youth, the type of goal framed matter to promote physical activity participation among low-active adolescents. More specifically, the main trial compared the effect of intrinsic and extrinsic-goal framing messages alongside planning to a control condition on low-active adolescents’ physical activity, intention, attitude, and exercise goals, and examined the potential meditational effect of these variables between condition and PA. Low-active students from (...) fifteen classes were assigned to one of these three conditions. PA was assessed using an accelerometer, and the socio-cognitive mediators were measured at baseline and post-test, and the intention was measured again at follow-up. Results showed that compared to adolescents in the CC group, those in the experimental conditions did not do more moderate PA, but carried out more light PA, and yielded an increase in attitude and intention. Mediational analysis revealed no significant effect of the potential mediators. (shrink)

Background: There is evidence that household point-of-use water treatment products can reduce the enormous burden of water-borne illness. Nevertheless, adoption among the global poor is very low, and little evidence exists on why. Methods: We gave 600 households in poor communities in Dhaka, Bangladesh randomly-ordered two-month free trials of four water treatment products: dilute liquid chlorine, sodium dichloroisocyanurate tablets, a combined flocculant-disinfectant powdered mixture, and a silver-coated ceramic siphon filter. Consumers also received education on the dangers of untreated drinking water. (...) We measured which products consumers used with self-reports, observation, and chlorine tests. We also measured drinking water's contamination with E. coli. Findings: Households reported highest usage of the filter, although no product had even 30% usage. E. coli concentrations in stored drinking water were generally lowest when households had Water Guard. Households that self-reported product usage had large reductions in E. coli concentrations with any product as compared to controls. Conclusion: Traditional arguments for the low adoption of POU products focus on affordability, consumers' lack of information about germs and the dangers of unsafe water, and specific products not meshing with a household's preferences. In this study we provided free trials, repeated informational messages explaining the dangers of untreated water, and a variety of product designs. The low usage of all products despite such efforts makes clear that important barriers exist beyond cost, information, and variation among these four product designs. Without a better understanding of the choices and aspirations of the target end-users, household-based water treatment is unlikely to reduce morbidity and mortality substantially in urban Bangladesh and similar populations. © 2011 Luoto et al.

This paper explores gender differences in “make-up” and “suspicion” in a bargaining game in which the privately informed seller of a company sends a value message to the uninformed potential buyer who then proposes a price for the company. “Make-up” is measured by how much the true value is overstated, “suspicion” by how much the price offer differs from the value message. We run different computerized treatments varying in information about the gender and in embeddedness of gender information. (...) The asymmetry of the game and of information allows for a robust assessment of gender effects. We report here the results from just one shot round decision since we expect such effects to be more pronounced for inexperienced participants. We mainly find an effect of gender constellation: when female sellers are aware to confront a female buyer, they overstate more, i.e. there is more “make-up”. However, we cannot confirm gender effects for suspicion. (shrink)

ArgumentDuring the second quarter of the nineteenth century, an argument raged about the identity of a small freshwater fish: was the parr a distinct species, or merely the young of the salmon? This “Parr Controversy” concerned both fishermen and ichthyologists. A central protagonist in the controversy was a man of ambiguous social and scientific status: a gamekeeper from Scotland named John Shaw. This paper examines Shaw’s heterogeneous practices and the reception of his claims by naturalists as he struggled to find (...) a footing on the “gradient of attributed competence” (Rudwick 1985). The case demonstrates the context-specific nature of expert-lay boundaries and identities and explores a range of material and linguistic resources available for negotiating them. Arguing for a view of Shaw’s trajectory as simultaneously one of being a “practical man” and of becoming a naturalist, the paper explores both the permeability of social hierarchies in knowledge production and their effective role in the regulation of competency.

This chapter aims to direct attention to the political dimension of the social media age. Although current events like the Cambridge Analytica data breach managed to raise awareness for the issue, the systematically organized and orchestrated mechanisms at play still remain oblivious to most. Next to dangerous monopoly-tendencies among the powerful players on the market, reliance on automated algorithms in dealing with content seems to enable large-scale manipulation that is applied for economical and political purposes alike. The successful replacement of (...) traditional parties by movements based on personality cults around marketable young faces like Emmanuel Macron or Austria’s Sebastian Kurz is strongly linked to products and services offered by an industry that simply provides likes and followers for cash. Inspired by Trump’s monopolization of the Twitter-channel, these new political acteurs use the potential of social media for effective message control, allowing them to avoid confrontations with professional journalists. In addition, an extremely active minority of organized agitators relies on the viral potential of the web to strongly influence and dictate public discourse – suggesting a shift from the Spiral of Silence to the dangerous illusion of a Nexus of Noise.

This study examines the effectiveness of the inoculation strategy in countering vaccine-related misinformation among Hong Kong college students. A three-phase between-subject experiment was conducted to compare the persuasive effects of inoculation messages, supportive messages, and no message control. The results show that inoculation messages were superior to supportive messages at generating resistance to misinformation, as evidenced by more positive vaccine attitudes and stronger vaccine intention. Notably, while we expected the inoculation condition would produce more resistance than the (...) class='Hi'>control condition, there was little evidence in favor of this prediction. Attitudinal threat and counterarguing moderated the experimental effects; issue involvement and political trust were found to directly predict vaccine attitudes and intention. The findings suggest that future interventions focus on developing preventive mechanisms to counter misinformation and spreading inoculation over the issue is an effective strategy to generate resistance to misinformation. Interventions should be cautious about using health advocacy initiated by governments among populations with low political trust. (shrink)

Despite a predominantly digital, 21st century music production landscape, analogue hardware professional audio technologies persist. In the discoursal throes of the leading online audio technology message forum Gearslutz, such technologies are routinely objectified, sexualized, fetishized and socialized into gear. Situated in a contemporary critical, interdisciplinary framework of fetish, masculinity and sexuality studies, this research interrogates how audio technologies manufactured and intended for music production contexts become sexy. Applying a mixed-mode methodology, including an intensive discourse, image and material-semiotic analysis of (...) an ‘epic’ sexy gear thread, we collated extensive data about technological fetishization. Sexy gear discourse articulates themes of voyeurism, acquisition, control and animation – linking the fetish value of technological objects and their connoisseurship with the erotic potential of sexualized objects. Such discourses ultimately serve to maintain social order, and become sites for performing the maintenance work of hegemonic masculine formations. This research provides new insights into how hegemonic masculinities depend upon the organization of online and offline sociability around fetishized material objects. Furthermore, our findings align with those of current scholarship focused on representational politics of technoculture. (shrink)
