AbstractDespite high mortality and morbidity, COPD remains under-diagnosed. Case-finding strategies are possible, but patients’ perspectives are unexplored. Using qualitative methods, we explored the patient perspective of a case-finding intervention among at-risk patients in primary care. Semi-structured telephone interviews were transcribed and thematic analysis utilised. Seven patients without (mean age 64.5 years (58–74), n = 4) and 8 with obstructed spirometry (mean age 63.5 (53–75), n = 4) were interviewed. Themes identified were motives, challenges and concerns regarding attending the clinic. These included wanting to be well; to help with research; concern over negative impact to life from COPD diagnosis; perceived utility of the clinic; quality of information given; staff manner, approachability and knowledge; and perceived effects of the clinic on lifestyle, self-management and symptoms. The intervention was generally deemed useful and reassuring, although shared information was too detailed or irrelevant for some. Several reported positive lifestyle changes, improved symptoms and improved self-management.

Abstract Destination memory errors (inability to remember to whom information was shared) affects all ages, but older adults are particularly vulnerable due to poor source monitoring. Individuals may assume information was already shared when it was not or repeat previously shared information. The current study explored two mental imagery strategies (vivid imagery, visualizing context) to improve destination memory. Using a software program, younger and older adults told randomly generated facts to random celebrity faces. Participants were unaware of the upcoming memory tests. The control group did not use a strategy. The imagery group used vivid imagery to connect the fact and face (e.g., visualize Oprah on a dime to remember Oprah was told that dimes have 118 ridges). The context group visualized a provided context (e.g., grocery store) when telling a fact to a face. Assessments of performance on item memory (facts, faces) as well as destination memory (face-fact pairings) were counterbalanced. Results indicated an associative memory deficit among older adults, which was driven by a higher rate of false alarms. However, across all adults, the vivid imagery condition was more accurate than the control condition, and they demonstrated fewer false alarms. These findings suggest that older adults can use mental imagery to reduce false alarms and improve destination memory performance. Implications include reducing age stereotypes, improving conversations, and decreasing potentially dangerous situations (e.g., withholding important health information thinking it already was shared with a doctor).

People have always shared information through chains and networks of testimony. It is arguably part of what makes us human and enables us to live in cooperative communities with populations greater than 150 or so. The invention of the internet and the rise of social media have turbocharged our ability to share information. This chapter develops a normative epistemic framework for sharing information online. This framework takes into account both ethical and epistemic considerations that are intertwined in typical cases of online testimony. The authors argue that, while the current state of affairs is not entirely novel, recent technological developments call for a rethinking of the norms of testimony, as well as the articulation of a set of virtuous dispositions that people would do well to cultivate in their capacity as conduits (not just sources or receivers) of information.

Purpose This paper aims to perform an exhaustive revision of relevant and recent related studies, which reveals that both extraction methods are currently used to analyze credibility on Twitter. Thus, there is clear evidence of the need of having different options to extract different data for this purpose. Nevertheless, none of these studies perform a comparative evaluation of both extraction techniques. Moreover, the authors extend a previous comparison, which uses a recent developed framework that offers both alternates of data extraction and implements a previously proposed credibility model, by adding a qualitative evaluation and a Twitter-Application Programming Interface (API) performance analysis from different locations. Design/methodology/approach As one of the most popular social platforms, Twitter has been the focus of recent research aimed at analyzing the credibility of the shared information. To do so, several proposals use either Twitter API or Web scraping to extract the data to perform the analysis. Qualitative and quantitative evaluations are performed to discover the advantages and disadvantages of both extraction methods. Findings The study demonstrates the differences in terms of accuracy and efficiency of both extraction methods and gives relevance to much more problems related to this area to pursue true transparency and legitimacy of information on the Web. Originality/value Results report that some Twitter attributes cannot be retrieved by Web scraping. Both methods produce identical credibility values when a robust normalization process is applied to the text (i.e. tweet). Moreover, concerning the time performance, Web scraping is faster than Twitter API and it is more flexible in terms of obtaining data; however, Web scraping is very sensitive to website changes. Additionally, the response time of the Twitter API is proportional to the distance from the central server at San Francisco.

Abstract Study question What are the characteristics of the psychological services for couples undergoing ART treatment in Italy? Summary answer In the 47% of ART clinics the psychologist is a stable member of the team whereas psychological services are used by 10–20% of couples. What is known already: ART treatments are complex and emotionally demanding for both men and women. During the procedure the couples often experience stress and several negative emotions. In Italy the Law 40/2004 establishes the guidelines for ART application. This law sustains the importance of offering psychological support to the people who undergo ART treatments at any stage of the medical procedure. However, in Italy there are no specific recommendations or protocols for psychological interventions in ART centres. Furthermore, there is little or no studies regarding the characteristics of the psychological services offered to those undergoing ART treatments. Study design, size, duration This observational study aims to explore the characteristics of psychological services in ART clinics. Therefore, the ART Italian National Register (National Health Institute) with the Department of Dynamic and Clinical Psychology and Health study (Sapienza University) proposed a national survay to the 306 Italian ART centres. The Medical Director of each centre was invited to participate by e-mail and to fill a questionnaire on an on-line platform. Data collection was between Jenuary to February 2020. Participants/materials, setting, methods The participation has been proposed to all the Italian ART centres (n = 306). 35 centres have been previously excluded because participating in the first phase of the study regarding the questionnaire construction. Around the 40% of the centres participated in the study (n = 113). The questionnaire contains 26 items with multiple response answers. It mainly explored: the presence of the psychologist in the ART centres, charachteristics of the intervention offered, percentage of couples using the psychological service. Main results and the role of chance In the 47% of ART centres the psychologist is a stable member of the team. The 38% of respondents reported that the psychologist works on call in the centre, the 18% reported that the psychologist is present in the centre 1–2 times a week whereas the 32% reported that the psychologist works in a private practice outside the centre. The reported percentages of couples using the psychological service are: 10–20% (69%), 20–30% (13%), 30–50% (5%), more than 50% (5%) and around the 100% (8%). The number of psychological sessions usually offered are: up to five (9%), four (13%), three (29%), two (27%), one (10%). Couples interventions represent the 73%, single patient intervention the 14%, whereas the 13% are group interventions. The 60% of respondent reported the absence of a protocol for psychological intervention in the ART centre whereas the 40% reported the presence of a protocol. In around the 50% of cases the psychological service represents an extra cost for the couple/individual. In the 60% of cases the psychologist is not involved in the team meeting, however the 87% of respondents reported that confronting with the psychologist on patients is percived as useful. Limitations, reasons for caution These results should be considered with cautions due to the rate of participation (around 40%). Furthermore, this is a national study and the charachteristics of psychological services offered in ART centres of different countries should be investigated. Wider implications of the findings: In conclusion, the results show that psychological services in Italian ART centers are not yet fully operational and integrated in the ART procedure. All of this highlights the importance of further investigations with the aim to shared information to use to establish common protocols for psychological interventions in ART centres.

Decades post 1990 have seen rapid globalisation and technological advancement in the field of e-commerce, exposing consumers in emerging economies to an earlier unavailable wider range of foreign products and brands. Although the preference for both foreign and domestic products largely depends on consumer biases, studies show that shared information can influence consumer decision-making. This study aims to investigate the Indian consumers’ intentions towards foreign brands for apparel products. Using the theoretical foundation of the Theory of Planned Behaviour (TPB) and Social Exchange Theory (SET), the collected primary survey of 204 Indian consumers across a single product category (apparel) was analysed using Structural Equation Modelling (SEM). The study determined that both “product reviews” and “informal word-of-mouth” discussions have a positive and significant impact on consumer’s preference towards foreign brands. Further, the quality of information shared also plays a significant role in foreign brand preference. We also found evidence that an increase in income positively influences behaviour, however, the level of education has a negative influence. The findings of the study might serve as a roadmap for any foreign apparel brand looking to establish itself in an emerging market like India.

Whether category information is discretely localized or represented widely in the brain remains a contentious issue. Initial functional MRI studies supported the localizationist perspective that category information is represented in discrete brain regions. More recent fMRI studies using machine learning pattern classification techniques provide evidence for widespread distributed representations. However, these latter studies have not typically accounted for shared information. Here, we find strong support for distributed representations when brain regions are considered separately. However, localized representations are revealed by using analytical methods that separate unique from shared information among brain regions. The distributed nature of shared information and the localized nature of unique information suggest that brain connectivity may encourage spreading of information but category-specific computations are carried out in distinct domain-specific regions. NEW & NOTEWORTHY Whether visual category information is localized in unique domain-specific brain regions or distributed in many domain-general brain regions is hotly contested. We resolve this debate by using multivariate analyses to parse functional MRI signals from different brain regions into unique and shared variance. Our findings support elements of both models and show information is initially localized and then shared among other regions leading to distributed representations being observed.
