Cultural adaptation of the Smiling is Fun program for the treatment of depression in the Ecuadorian public health care system: A study protocol for a…
2021
Background Depression is one of the world's major health problems. Due to its high prevalence, it constitutes the first cause of disability among the Americas, where only a very low percentage of the population receives the adequate evidence-based psychological treatment. Internet-Based Interventions (IBIs) are a great alternative to reduce the treatment gap for mental disorders. Although there are several studies in low-and middle-income countries proving IBIs' feasibility and acceptability, there is still little evidence of the effectiveness in diverse social and cultural contexts such as Latin America. Methods Two studies will be described: Study 1 is focused on the cultural adaptation o…
Measuring Uncertainty in the Portfolio Selection Problem
2018
In this paper, we propose a new index for ranking portfolios based on the credibility expected return and loss on their investment. We assume that the return on a given portfolio is modeled as a trapezoidal fuzzy variable, whose credibility distribution is built using the data set of its historical returns. The credibilistic loss on the investment for a given portfolio is measured by means of a suitable loss function. In order to take risk-adverse investor attitudes into account, we analyze the performance of some credibility measures related to loss and risk on the investment for a given portfolio and their relationship with similar possibility measures. A numerical example is presented sh…
Are mandatory non-financial disclosures credible? Evidence from Italian listed companies
2020
According to the Directive 2014/95/EU on non‐financial information (NFI), from 2017 onwards, large companies of member states must provide social, environmental, and governance disclosures. This paper, focusing on the evaluation of the credibility of NFI in Italy after the implementation of the EU Directive, aims to investigate whether making non‐financial disclosures (NFDs) obligatory affect their credibility. From a theoretical perspective of material legitimacy theory, we investigated the NFDs of the 31 FTSE MIB Italian listed companies for the 2017 fiscal year. Through a meaning‐oriented content analysis, we developed a self‐constructed credibility index applying an operational framewor…
Multiple viewpoints increase students' attention to source features in social question and answer forum messages
2016
International audience; Social question & answer forums offer great learning opportunities, but students need to evaluate the credibility of answers to avoid being misled by untrustworthy sources. This critical evaluation may be beyond the capabilities of students from primary and secondary school. We conducted 2 studies to assess how students from primary, secondary, and undergraduate education perceive and use 2 relevant credibility cues in forums: author's identity and evidence used to support his answer. Students didn't use these cues when they evaluated forums with a single answer (Experiment 1), but they recommended more often answers from self‐reported experts than from users with a …
Early-design improvement of human reliability in an experimental facility: A combined approach and application on SPES
2019
Abstract SPES (Selective Production of Exotic Species) is a second-generation Isotope Separation On-Line (ISOL) facility for advanced nuclear physics applications, currently under construction at INFN (National Institute of Nuclear Physics) of Legnaro, Italy. Despite the potentially important safety implications of human errors for ISOL facilities, only a limited number of studies addressing this issue have been performed worldwide. This paper tries to address this need by means of an integrated approach of Hierarchical Task Analysis (HTA) and three human error quantification methods: HEART (in an enhanced version), SPAR-H, and CREAM. The application of multiple Human Reliability Analysis (…
Selection and evaluation of Internet information by adults with intellectual disabilities
2018
Internet offers people with intellectual disabilities (ID) unique opportunities to access information and to participate in society. But concerns have been raised about the potential risks they face when accessing the Internet (e.g. giving credit to false information, being exposed to manipulative content). As part of the current debate between positive risk-taking and overprotection, our study empirically tested the extent to which 43 adults with ID identified and selected topically relevant as well as trustworthy web pages while searching the Internet for several topics (e.g. Can social networks use your pictures for advertisement?). Participants also justified their search decisions. Res…
Ważność kryteriów oceny wiarygodności witryn internetowych na podstawie badań
2019
Wiarygodność witryny internetowej oznacza przeświadczenie użytkownika, że jego oczekiwania dotyczące otrzymania określonych informacji z tej witryny zostaną spełnione bez ponoszenia dodatkowych, nieuzasadnionych kosztów: ekonomicznych, społecznych, psychologicznych, prawnych, etycznych. Dokonywanie oceny wiarygodności witryn wymaga jej konceptualizacji i operacjonalizacji. W literaturze przedmiotu zidentyfikowano różne wymiary wiarygodności witryn oraz wiele zestawów kryteriów jej oceny. Jednak w zasadzie brak jest określenia ważności poszczególnych kryteriów, co pozwoliłoby na tworzenie rankingów witryn. Dlatego celem wstępnych badań przeprowadzonych metodą sondażową było wypełnienie tej l…
Examining the structure of credibility evaluation when sixth graders read online texts
2023
Background Previous research indicates that students lack sufficient online credibility evaluation skills. However, the results are fragmented and difficult to compare as they are based on different types of measures and indicators. Consequently, there is no clear understanding of the structure of credibility evaluation. Objectives The present study sought to establish the structure of credibility evaluation of online texts among 265 sixth graders. Methods Students' credibility evaluation skills were measured with a task in which they read four online texts, two more credible (a popular science text and a newspaper article) and two less credible (a layperson's blog text and a commercial tex…
A model to assess the behavioral impacts of consultative knowledge based systems
1997
This paper develops a research model to study the behavioral impacts of consultative knowledge based systems (KBS). An experiment was conducted with 36 experienced MBA students in marketing management to explore to what extent their decisions were affected by the following factors: user participation in updating the knowledge-base of the KBS, ambiguity of decision setting, routinization of usage, and source credibility of the expertise embedded in the KBS. Results show that ambiguity and source credibility affect user acceptance of the KBS recommendation and cause them to revise decisions. Implications of these findings for the design of consultative KBS are discussed.
Not Funny? The Effects of Factual Versus Sarcastic Journalistic Responses to Uncivil User Comments
2016
Incivility in user comments on news websites has been discussed as a significant problem of online participation. Previous research suggests that news outlets should tackle this problem by interactively moderating uncivil postings and asking their authors to discuss more civilized. We argue that this kind of interactive comment moderation as well as different response styles to uncivil comments (i.e., factual vs. sarcastic) differently affect observers’ evaluations of the discussion atmosphere, the credibility of the news outlet, the quality of its stories, and ultimately observers’ willingness to participate in the discussions. Results from an online experiment show that factual responses…
