On the Relationship between Skepticism towards and Reactance to Health Messages: The Special Case of Online Communication on Tick-Borne Encephalitis
In general, health communication messages intend to change individuals’ behaviors, applying both cognitive reasoning and increasingly personal accounts to achieve these changes. Nonetheless, against the background of increasing skepticism towards scientific findings and patronizing message claims, health messages fail to achieve their intended results. By use of a quantitative survey with Austrian respondents (n = 271), the study at hand intends to uncover individuals’ level of skepticism towards Tick-Borne Encephalitis (TBE) as well as their evaluations of online vaccination-related information on TBE. Moreover, as skepticism is likely to lead individuals to reject health message content altogether, we also test for the relationship between skepticism and reactance. Results indicate that there is only a marginal relationship between the two variables in the TBE communication context. For this reason, other variables might have to be included in future research to derive more comprehensive results and recommendations. Since skepticism has proven to be of lesser importance in TBE message reception, government or health officials are recommended to prioritize additional constructs, such as trust, which can be elevated through more affective communication
Health and Scientific Frames in Online Communication of Tick-Borne Encephalitis: Antecedents of Frame Recognition
Health and Scientific Frames in Online Communication of Tick-Borne Encephalitis: Antecedents of Frame Recognition
In a period characterized by vaccine hesitancy and even vaccine refusal, the way online information on vaccination is presented might affect the recipients’ opinions and attitudes. While research has focused more on vaccinations against measles or influenza, and described how the framing approach can be applied to vaccination, this is not the case with tick-borne encephalitis, a potentially fatal infection induced by tick bites. This study takes one step back and seeks to investigate whether health and scientific frames in online communication are even recognized by the public. Moreover, the influence of selected health- and vaccine-related constructs on the recognition of frames is examined. Study results indicate that health frames are the most easily identified and that their use might be a fruitful strategy when raising awareness of health topics such as vaccination
Potentials and Limitations of Educational Videos on YouTube for Science Communication
YouTube has become a complement learning platform which fosters learning on demand with educational videos. Educational videos are understood as a fruitful strategy to enhance the user’s knowledge and are applied in schools, as well as in science communication, e.g., to inform about climate change. This paper discusses two perspectives which become visible in the current research literature on educational videos on YouTube. First, studies assume that watching educational videos changes the attitude or behavior of the recipients. Second, studies question whether educational videos have a higher impact than other information materials such as texts. We frame both perspectives with regard to theories from media effect studies and learning concepts from education science and discuss their conclusions for educational videos on YouTube. We will first focus on students as a target group for educational videos, but in the further course, we will discuss the results for the public as targeted group of science communication as well. In the final section we will summarize which potentials and limitations educational videos have for educational purposes in science communication
Feature-Based Attention Affects Direction-Selective fMRI Adaptation in hMT+
Functional magnetic resonance adaptation has been successfully used to reveal direction-selective responses in the human motion complex (hMT+). Here, we aimed at further investigating direction-selective as well as position-selective responses of hMT+ by looking at how these responses are affected by feature-based attention. We varied motion direction and position of 2 consecutive random-dot stimuli. Participants had to either attend to the direction or the position of the stimuli in separate runs. We show that direction selectivity in hMT+ as measured by functional magnetic resonance imaging (fMRI) adaptation was strongly influenced by task set. Attending to the motion direction of the stimuli lead to stronger direction-selective fMRI adaptation than attending to their position. Position selectivity, on the other hand, was largely unaffected by attentional focus. Interestingly, the change in the direction-selective adaptation profile across tasks could not be explained by inheritance from earlier areas. The response pattern in the early retinotopic cortex was stable across conditions. In conclusion, our results provide further evidence for the flexible coding of direction information in hMT+ depending on task demand
Sleep and academic performance in Indigenous Australian children from a remote community: An exploratory studyjpc_2059 122
Aim: Disruptions to sleep in childhood are associated with poor behaviour and deficits in academic performance and executive function. Although academic performance of indigenous children from remote communities in Australia is documented as well below that of non- indigenous children, the extent of sleep disruption and its contribution to academic performance among this population has not been assessed. This pilot study aimed to objectively assess the sleep of remote indigenous children and the association between sleep disruption and both academic performance and executive function.
Method: Twenty-one children from a remote Australian indigenous community aged 6–13 years wore actigraphy for two consecutive nights, reported subjective sleepiness, and were objectively assessed for academic performance (Wechsler Individual Achievement Test, 2nd Edition) and executive function (NEuroloPSYcological Assessment-II). Results: Results show marked reduction in sleep time, sleep fragmentation, academic performance and auditory attention compared with non-indigenous norms. Sleep duration was not associated with performance, possibly because of reduced sleep and performance observed across the entire group. Sleep fragmentation was associated with reduced reading and numerical skills (P \u3c 0.05).
Conclusions: The sleep of indigenous children in remote communities is an important area of future inquiry, and our initial findings of poor sleep and an association between sleep disruption and academic performance may have important implications for intervention strategies aimed at ‘closing the gap’. Further studies should assess a broader range of demographic, social and economic factors to better understand the associations reported here and guide future intervention

Marriage as a Mechanism: Women’s Education and Wealth in Malawi
Research has found that in the United States women have greater economic returns to a college degree than men, because of more stable marriages and other family income. Using cross-sectional data of women aged 19-40 years in Malawi from the Malawi Longitudinal Study of Families and Health (n = 898), we test whether higher education is associated with these same benefits in a context with lower educational attainment levels, fewer job opportunities, and different marriage patterns. We find that better educated women are more likely to have better educated spouses and higher household wealth. Though divorce is negatively associated with wealth, we do not find an association between education and divorce. This analysis provides motivation for further research on the how education is associated with outcomes for women in developing countries
Heteroduplex analysis of T-cell receptor γ gene rearrangement as an adjuvant diagnostic tool in skin biopsies for erythroderma
Erythroderma, defined as red skin covering most of the body surface often accompanied or followed by exfoliation, is the clinical manifestation of at least six different underlying etiologies with allergic or irritant contact dermatitis, atopic/asteotic dermatitis, pityriasis rubra pilaris (PRP), psoriasis, and seborrheic dermatitis accounting for the majority of cases. Approximately 10% of cases are due to adverse drug reactions with roughly another 10% due to cutaneous T-cell lymphoma (CTCL), predominantly mycosis fungoides, or leukemia. It is clear from multiple studies that the clinical diagnosis of the underlying entity is often difficult, as these diseases can present in a very similar fashion. A skin biopsy is usually employed in this setting as a diagnostic tool. However, the histopathologic diagnosis of the underlying cause is complicated by the subtlety of the distinguishing histologic features. In this situation, an ancillary technique demonstrating the presence of a monoclonal T-cell proliferation could help to rule in or out CTCL in cases that clinically and histopathologically do not allow a definitive diagnosis. Methods: We retrospectively studied 25 biopsies from sixteen patients who presented to the Stanford Dermatology Clinic with erythroderma. We examined the specimens morphologically and analyzed the gamma chain of the T-cell receptor (TCR- γ) by polymerase chain reaction (PCR) followed by heteroduplex analysis for clonality. We then correlated the results of our PCR and heteroduplex analyses with the patients’ clinical outcomes. Results: Four biopsies, from three patients, contained clonal TCR-γ rearrangements; the four biopsies, all of which were equivocal histologically, correlated to diagnoses of mycosis fungoides (MF) or SÉzary syndrome (SS). Twenty-one biopsies contained polyclonal T-cell populations. Eighteen of these biopsies represent patients with inflammatory dermatoses. Three of these biopsies, all of which were taken from a single patient, correlate to a diagnosis of MF. Conclusion: TCR-γ PCR heteroduplex analysis seems to represent an important adjuvant diagnostic tool that, used in conjunction with histopathology and clinical history, could help to clarify the underlying etiology of erythroderma.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/72286/1/j.1600-0560.2001.280703.x.pd
The State of Prototyping Practice in the Industrial Setting: Potential, Challenges and Implications
Prototyping as a central method within innovation- and product development processes has a high acceptance in industry. Various prototyping tools provide impressive visualizations of product ideas in early development stages and especially low fidelity prototyping methods seem easily applicable. However, a closer look at prototyping in practice reveals a number of misunderstandings and barriers regarding effective prototyping, often related to different stakeholders’ (e.g., developer, designer, client) ideas about the purpose of prototyping. Based on a combination of literature analysis, adapting existing models and methods in user centered design (e.g., personas, double diamond design process) and empirical results from industrial research cooperation, we introduce a focus group format and a first model of prototyping maturity, which can help organizations to reflect on their state of practice in prototyping on an individual, team, and organizational level. The maturity model also forms a valuable theoretical lens for design research. Thus, our research aims at researchers in the field of prototyping as well as practitioners involved in prototyping and innovation processes
