Scientific citizenship and television in Ireland: a study of production, content and audience reception

Because of increasing dependence on scientific knowledge, citizens, if they are to participate democratically in society, need to be able to take part in decision-making about scientific issues. The ideal of citizenship has always included the concepts of rights and obligations; the notion of scientific citizenship (Irwin 2001) can be perceived as a normative ideal which implies not only that scientific knowledge is important for citizenship in contemporary society but also that citizens can lay a legitimate claim about accountability in scientific research. Citizens interact with science through the mass media, particularly television, which is such a part of the routine of daily life. This interaction is part of their cultural citizenship, the idea of individuals patching together an identity as citizen from all available sources, including mass media, using everyday media texts and culture to understand, take up, reflect on and reform identities that are embedded in communities of different kinds. This thesis examines scientific citizenship by looking at how publics use ‘science on television’ as part of an ethno-epistemic assemblage to inform their everyday actions. Television fits into this assemblage as television viewing practices are embedded in everyday life; this means that local contexts of text–reader interaction are a salient part of ethno-epistemic assemblages. Thematic representations of the assemblages of ‘science on television’ emerged from a production–content–reception analysis of science on Irish television, a framework known as the circuit of mass communication. This research privileges the reception analysis, which was carried out with focus groups of television viewers, because in talking together citizens construct and shape their responses to science on television. The analysis follows how focus group participants, as non-experts, participate in science by talk; speaking is,indeed, their political action, and they use the resources of their particular ethno-epistemic assemblages to construct and contest their paths to knowledge. This is a positive view of the potential of the idea of scientific citizenship. However, this potential is not matched by the television content on offer, which is too often formulaic and uncritical of the institutions of science. I call for an ethos of public journalism which emphasises the relationship between the practice of journalism and the democratic work of citizens in a self-governing republic, and suggest that television journalists and producers are ideally suited to help constitute vital “publics” to deliberate complex issues and engage in collective problem-solving activities. Critical comment on science is a crucial aspect of this public journalism, and television, in conjunction with new media, can become a forum for scientists to hold an interactive dialogue with citizens. Focus group participants are already negotiating their scientific citizenship through talk, and scientists and policy makers need to join these discussions, as science, and its consequences, does not end at the laboratory bench

Adaptive Choice-Based Conjoint Analysis

Conjoint analysis (CA) has emerged as an important approach to the assessment of health service preferences. This article examines Adaptive Choice-Based Conjoint Analysis (ACBC) and reviews available evidence comparing ACBC with conventional approaches to CA. ACBC surveys more closely approximate the decision-making processes that influence real-world choices. Informants begin ACBC surveys by completing a build-your-own (BYO) task identifying the level of each attribute that they prefer. The ACBC software composes a series of attribute combinations clustering around each participant’s BYO choices. During the Screener section, informants decide whether each of these concepts is a possibility or not. Probe questions determine whether attribute levels consistently included in or excluded from each informant’s Screener section choices reflect ‘Unacceptable’ or ‘Must Have’ simplifying heuristics. Finally, concepts identified as possibilities during the Screener section are carried forward to a Choice Tournament. The winning concept in each Choice Tournament set advances to the next choice set until a winner is determined. A review of randomized trials and cross-over studies suggests that, although ACBC surveys require more time than conventional approaches to CA, informants find ACBC surveys more engaging. In most studies, ACBC surveys yield lower standard errors, improved prediction of hold-out task choices, and better estimates of real-world product decisions than conventional choice-based CA surveys

An analysis of people-meter data

Beginning with a differentiation of science programmes into five different editorial concepts, this article explores the audience reach of science on television in 10 European countries with a special emphasis on young audiences aged between 14 and 29 years. In relation to the share of this age group in the entire population, science programmes in all countries reach a considerably smaller proportion of younger viewers. Specific preferences for science content on television do not seem to be relevant in explaining aggregated viewing behaviours especially of young audiences. Unlike all other segments, the young science viewer segment is almost intangible as an aggregated group, as a definable segment of a mass audience that can be targeted by science programme makers

Mass media and risk factors for cancer: the under-representation of age

BACKGROUND: Increasing age is a risk factor for developing cancer. Yet, older people commonly underestimate this risk, are less likely to be aware of the early symptoms, and are more likely to be diagnosed with advanced stage cancer. Mass media are a key influence on the public's understanding health issues, including cancer risk. This study investigates how news media have represented age and other risk factors in the most common cancers over time. METHODS: Eight hundred articles about the four most common cancers (breast, prostate, lung and colorectal) published within eight UK national newspapers in 2003, 2004, 2013 and 2014 were identified using the Nexis database. Relevant manifest content of articles was coded quantitatively and subjected to descriptive statistical analysis in SPSS to identify patterns across the data. RESULTS: Risk was presented in half of the articles but this was rarely discussed in any depth and around a quarter of all articles introduced more than one risk factor, irrespective of cancer site. Age was mentioned as a risk factor in approximately 12% of all articles and this varied by cancer site. Age was most frequently reported in relation to prostate cancer and least often in articles about lung cancer. Articles featuring personal narratives more frequently focused on younger people and this was more pronounced in non-celebrity stories; only 15% of non-celebrity narratives were about people over 60. Other common risks discussed were family history and genetics, smoking, diet, alcohol, and environmental factors. Family history and genetics together featured as the most common risk factors. Risk factor reporting varied by site and family history was most commonly associated with breast cancer, diet with bowel cancer and smoking with lung cancer. CONCLUSION: Age and older adults were largely obscured in media representation of cancer and cancer experience. Indeed common risk factors in general were rarely discussed in any depth. Our findings will usefully inform the development of future cancer awareness campaigns and media guidelines. It is important that older adults appreciate their heightened risk, particularly in the context of help-seeking decisions

Engagement of Community Stakeholders to Develop a Framework to Guide Research Dissemination to Communities

Background: Dissemination of research findings to past study participants and the community-at-large is important. Yet, a standardized process for research dissemination is needed to report results to the community. Objective: We developed a framework and strategies to guide community-academic partnerships in community-targeted, dissemination efforts. Methods: From 2017 to 2019, a community-academic partnership was formed in Nashville, Tennessee, and iteratively developed a framework and strategies for research dissemination using cognitive interviews. A deductive, constant comparative analysis was conducted on interview responses to examine framework and strategy content. Feedback was used to finalize the framework and strategies for the evaluation. Using existing data, the framework\u27s utility was evaluated in seven town hall meetings (n = 117). Bivariate analyses determined its effect on community members’ trust and willingness to participate in research using pre- and post-surveys. Evaluation results were used to finalize the framework. Results: The Community-Engaged Research Dissemination (CERD) framework has two phases. Phase one is a preliminary planning phase with two steps, and phase two is the four-step dissemination process. There are five standards to be upheld conducting these phases. We provide competencies for each component. Three feasible, culturally adapted strategies were developed as exemplars to disseminate research findings. Using pre- and post-surveys for intervention evaluation, there was a significant difference in trust in medical research and researchers (P = .006) and willingness to participate in research (P = .013). Discussion and Conclusion: The CERD framework can potentially standardize the process and compare the effect of dissemination efforts on the community\u27s trust and willingness to participate in research

Dysregulation of endothelial cell connexin-43 localisation in response to doxorubicin

Introduction: Anthracyclines, such as doxorubicin, remain an important class of chemotherapeutic agent however their efficacy in treating cancer is limited by a cumulative dose-dependent cardiotoxicity. Whilst most studies have focused on cardiomyocyte impairment, circulating doxorubicin has been shown to impact human microvascular responses to doxorubicin in coronary vessels.1 Studies show increased endothelial cell permeability resulting in increased paracellular permeability due to damage to the integrity of cell-cell junctions.2 Strategies to maintain vessel integrity and prevent endothelial cell dysregulation could represent a novel therapeutic opportunity to limit the toxic effects of doxorubicin. The aim of this project was to assess the impact of doxorubicin upon endothelial gap junction proteins, in particular connexin-43 (Cx43)

Evaluating pharmacist input into the pharmaceutical care of patients in dispensing medical practices in remote and rural areas of Scotland.

Background. - The Highlands and the Western Isles are the two most remote and rural areas of Scotland, with many medical practices in areas where pharmacies would not be viable. Recent regulations state that that dispensing medical practices in these areas must receive pharmacist support for patients who would benefit. Objective. - This study aimed to evaluate pilot services, which centred on the provision of patient centred pharmaceutical care. Methods. A realist type evaluation was conducted by an independent research team comprising collecting quantitative data around what occurred during the consultation followed by interviews with purposive samples of staff (n = 14) and patients (n = 18). Results. - A total of 873 medicines related issues were identified in 473 patients reviewed, with the main issue being 'inappropriate dose, frequency, duration'. Just under half (39.7%) of issues were managed by the pharmacist without any medical input. Interviews indicated a high level of appreciation, although there was an increase in workload for some staff. While the need for telephone based pharmacist consultations for some patients was understood, there was a preference for face to face. All were supportive of continuing and extending the service. Conclusion. - The clinical pharmacist service was both needed and valued highly by staff and patients. In Scotland, this aligns with the Government vision and action plan, 'Prescription for Excellence', that by 2023 all patient facing pharmacists will be independent prescribers with those in remote and rural areas entitled to 'equity of access to such expertise'

VEGF and the Fab fragment of a humanized neutralizing antibody: crystal structure of the complex at 2.4 å resolution and mutational analysis of the interface

AbstractBackground: Vascular endothelial growth factor (VEGF) is a highly specific angiogenic growth factor; anti-angiogenic treatment through inhibition of receptor activation by VEGF might have important therapeutic applications in diseases such as diabetic retinopathy and cancer. A neutralizing anti-VEGF antibody shown to suppress tumor growth in an in vivo murine model has been used as the basis for production of a humanized version.Results: We present the crystal structure of the complex between VEGF and the Fab fragment of this humanized antibody, as well as a comprehensive alanine-scanning analysis of the contact residues on both sides of the interface. Although the VEGF residues critical for antibody binding are distinct from those important for high-affinity receptor binding, they occupy a common region on VEGF, demonstrating that the neutralizing effect of antibody binding results from steric blocking of VEGF–receptor interactions. Of the residues buried in the VEGF–Fab interface, only a small number are critical for high-affinity binding; the essential VEGF residues interact with those of the Fab fragment, generating a remarkable functional complementarity at the interface.Conclusions: Our findings suggest that the character of antigen–antibody interfaces is similar to that of other protein–protein interfaces, such as ligand–receptor interactions; in the case of VEGF, the principal difference is that the residues essential for binding to the Fab fragment are concentrated in one continuous segment of polypeptide chain, whereas those essential for binding to the receptor are distributed over four different segments and span across the dimer interface

Lung cancer symptom appraisal among people with chronic obstructive pulmonary disease: A qualitative interview study

© 2019 The Authors. Psycho-Oncology Published by John Wiley & Sons Ltd. Objective: The incidence of lung cancer is four times higher in people with chronic obstructive pulmonary disease (COPD) compared with the general population. Promotion of a shorter time from symptom onset to presentation is one potential strategy for earlier lung cancer diagnosis, but distinguishing respiratory symptoms can be difficult. We investigated how the experience of COPD influences symptom appraisal and help seeking for potential lung cancer symptoms. Methods: We conducted qualitative interviews with men (n = 17) and women (n = 23) aged 40 to 83 years with COPD. Topic guides drew on the integrated symptom-response framework and covered symptom experience, interpretation, action, recognition, help seeking, evaluation, and reevaluation. We used the framework method to analyse the data. Results: Participants said that they attributed chest symptoms to their COPD; no other cause was considered. Participants said that family/friends noticed changes in their symptoms and encouraged help seeking. Others felt isolated by their COPD because they could not get out, were fatigued, or were embarrassed. Participants visited health professionals frequently, but increased risk of lung cancer was not discussed. Conclusions: Our study provides insight into different levels of influence on symptom appraisal and targets for intervention. Greater awareness of increased lung cancer risk and support to act on symptom changes is essential and could be achieved through a concerted information campaign. Health professionals working with people with COPD could also optimise appointments to support symptom appraisal of potential lung cancer symptoms
