Persuasive Technology for Learning in Business Context
"Persuasive Design is a relatively new concept which employs general principles of persuasion that can be implemented in persuasive technology. This concept has been introduced by BJ Fogg in 1998, who since then has further extended it to use computers for changing attitudes and behaviour. Such principles can be applied very well in learning and teaching: in traditional human-led learning, teachers always have employed persuasion as one of the elements of teaching. Persuasive technology moves these principles into the digital domain, by focusing on technology that inherently stimulates learners to learn more quickly and effectively. This is very relevant for the area of Business Management in several aspects: Consumer Behavior, Communications, Human Resource, Marketing & Advertising, Organisational Behavior & Leadership. The persuasive principles identified by BJ Fogg are: reduction, tunnelling, tailoring, suggestion, self-monitoring, surveillance, conditioning, simulation, social signals. Also relevant is the concept of KAIROS, which means the just-in-time, at the right place provision of information/stimulus. In the EuroPLOT project (2010-2013) we have developed persuasive learning objects and tools (PLOTs) in which we have applied persuasive designs and principles. In this context, we have developed a pedagogical framework for active engagement, based on persuasive design in which the principles of persuasive learning have been formalised in a 6-step guide for persuasive learning. These principles have been embedded in two tools â PLOTmaker and PLOTLearner â which have been developed for creating persuasive learning objects. The tools provide specific capability for implementing persuasive principles at the very beginning of the design of learning objects. The feasibility of employing persuasive learning concepts with these tools has been investigated in four different case studies with groups of teachers and learners from realms with distinctly different teaching and learning practices: Business Computing, language learning, museum learning, and chemical substance handling. These case studies have involved the following learner target groups: school children, university students, tertiary students, vocational learners and adult learners. With regards to the learning context, they address archive-based learning, industrial training, and academic teaching. Alltogether, these case studies include participants from Sweden, Africa (Madagascar), Denmark, Czech Republic, and UK. One of the outcomes of this investigation was that one cannot apply a common set of persuasive designs that would be valid for general use in all situations: on the contrary, the persuasive principles are very specific to learning contexts and therefore must be specifically tailored for each situation. Two of these case studies have a direct relevance to education in the realm of Business Management: Business Computing and language learning (for International Business). In this paper we will present the first results from the evaluation of persuasive technology driven learning in these two relevant areas.
Comparison Between Wolfe, Boyd, BI-RADS and TabĂĄr Based Mammographic Risk Assessment
Abstract. Mammographic risk assessment provides an indication of the likelihood of women developing breast cancer. Anumber ofmammographic image based classification methods have been developed, such as Wolfe, Boyd, BI-RADS and TabaĚr based assessment. We provide a comparative study of these four approaches. Results on the full MIAS database are presented, which indicate strong correlation (Spearmanâs> 0.9) between Wolfe, Boyd andBI-RADSbased classification, whilst the correlation with TabaĚr based classification is less straight forward (Spearmanâs < 0.5, but low correlations mainly caused by one of the classes).
Disrespect and abuse as a predictor of postnatal care utilisation and maternal-newborn well-being: a mixed-methods systematic review
INTRODUCTION: Globally, a substantial number of women experience abusive and disrespectful care from health providers during childbirth. As evidence mounts on the nature and frequency of disrespect and abuse (D&A), little is known about the consequences of a negative experience of care on health and well-being of women and newborns. This review summarises available evidence on the associations of D&A of mother and newborns during childbirth and the immediate postnatal period (understood as the first 24 hours from birth) with maternal and neonatal postnatal care (PNC) utilisation, newborn feeding practices, newborn weight gain and maternal mental health. METHODS: We conducted a systematic review of all published qualitative, quantitative and mixed-methods studies on D&A and its postnatal consequences across all countries. Pubmed, Embase, Web of Science, LILACS and Scopus were searched using predetermined search terms. Quantitative and qualitative data were analysed and presented separately. Thematic analysis was used to synthesise the qualitative evidence. RESULTS: A total of 4 quantitative, 1 mixed-methods and 16 qualitative studies were included. Quantitative studies suggested associations between several domains of D&A and use of PNC as well as maternal mental health. Different definitions of exposure meant formal meta-analysis was not possible. Three main themes emerged from the qualitative findings associated with PNC utilisation: (1) women's direct experiences; (2) women's expectations and (3) women's agency. CONCLUSION: This review is the first to examine the postnatal effect of D&A of women and newborns during childbirth. We highlight gaps in research that could help improve health outcomes and protect women and newborns during childbirth. Understanding the health and access consequences of a negative birth experience can help progress the respectful care agenda
Comparing the Efficacy of an Identical, Tailored Smoking Cessation Intervention Delivered by Mobile Text Messaging Versus Email: Randomized Controlled Trial
Source at https://doi.org/10.2196/12137.Background - There is a need to deliver smoking cessation support at a population level, both in developed and developing countries. Studies on internet-based and mobile phoneâbased smoking cessation interventions have shown that these methods can be as effective as other methods of support, and they can have a wider reach at a lower cost.
Objective - This randomized controlled trial (RCT) aimed to compare, on a population level, the efficacy of an identical, tailored smoking cessation intervention delivered by mobile text messaging versus email.
Methods - We conducted a nationwide 2-arm, double-blinded, fully automated RCT, close to a real-world setting, in Norway. We did not offer incentives to increase participation and adherence or to decrease loss to follow-up. We recruited users of the website, slutta.no, an open, free, multi-component Norwegian internet-based smoking cessation program, from May 2010 until October 2012. Enrolled smokers were considered as having completed a time point regardless of their response status if it was 1, 3, 6, or 12 months post cessation. We assessed 7315 participants using the following inclusion criteria: knowledge of the Norwegian language, age 16 years or older, ownership of a Norwegian cell phone, having an email account, current cigarette smoker, willingness to set a cessation date within 14 days (mandatory), and completion of a baseline questionnaire for tailoring algorithms. Altogether, 6137 participants were eligible for the study and 4378 participants (71.33%) provided informed consent to participate in the smoking cessation trial. We calculated the response rates for participants at the completed 1, 3, 6, and 12 months post cessation. For each arm, we conducted an intention-to-treat (ITT) analysis for each completed time point. The main outcome was 7-day self-reported point prevalence abstinence (PPA) at the completed 6 months post cessation. We calculated effect size of the 7-day self-reported PPA in the text message arm compared with the email arm as odds ratios (ORs) with 95% CIs for the 4 time points post cessation.
Results - At 6 months follow-up, 21.06% (384/1823) of participants in the text message arm and 18.62% (333/1788) in the email arm responded (P=.07) to the surveys. In the ITT analysis, 11.46% (209/1823) of participants in the text message arm compared with 10.96% (196/1788) in the email arm (OR 1.05, 95% CI 0.86-1.30) reported to have achieved 7 days PPA.
Conclusions - This nationwide, double-blinded, large, fully automated RCT found that 1 in 9 enrolled smokers reported 7-day PPA in both arms, 6 months post cessation. Our study found that identical smoking cessation interventions delivered by mobile text messaging and email may be equally successful at a population level
Persuasive Technology for Learning and Teaching â The EuroPLOT Project
The concept of persuasive design has demonstrated its benefits by changing human behavior in certain situations, but in the area of education and learning, this approach has rarely been used. To change this and to study the feasibility of persuasive technology in teaching and learning, the EuroPLOT project (PLOT = Persuasive Learning Objects and Technologies) has been funded 2010-2013 by the Education, Audiovisual and Culture Executive Agency (EACEA) in the Life-long Learning (LLL) programme. In this program two tools have been developed (PLOTMaker and PLOTLearner) which allow to create learning objects with inherently persuasive concepts embedded. These tools and the learning objects have been evaluated in four case studies: language learning (Ancient Hebrew), museum learning (Kaj Munk Museum, Denmark), chemical handling, and academic Business Computing. These case studies cover a wide range of different learning styles and learning groups, and the results obtained through the evaluation of these case studies show the wide range of success of persuasive learning. They also indicate the limitations and areas where improvements are required
The cysteine 34 residue of A1M/Îą1-microglobulin is essential for protection of irradiated cell cultures and reduction of carbonyl groups.
ι1-microglobulin (A1M) is a 26 kDa plasma and a tissue protein belonging to the lipocalin family. The reductase and free radical scavenger A1M has been shown to protect cells and extracellular matrix against oxidative and irradiation-induced damage. The reductase activity was previously shown to depend upon an unpaired cysteinyl side-chain, C34, and three lysyl side-chains, K92, 118, and 130, located around the open end of the lipocalin pocket. The aim of this work was to investigate whether the cell and matrix protection by A1M is a result of its reductase activity by using A1M-variants with site-directed mutations of the C34, K92, K118, and K130 positions. The results show that the C34 side-chain is an absolute requirement for protection of HepG2 cell cultures against alpha-particle irradiation-induced cell death, upregulation of stress response and cell cycle regulation genes. Mutation of C34 also resulted in loss of the reduction capacity toward heme- and hydrogen peroxide-oxidized collagen, and the radical species 2,2´-azino-bis (3-ethyl-benzo-thiazoline-6-sulphonic acid) (ABTS). Furthermore, mutation of C34 significantly suppressed the cell-uptake of A1M. The K92, K118, and K130 side-chains were of minor importance in cell protection and reduction of oxidized collagen but strongly influenced the reduction of the ABTS-radical. It is concluded that antioxidative protection of cells and collagen by A1M is totally dependent on its C34 amino acid residue. A model of the cell protection mechanism of A1M should be based on the redox activity of the free thiolyl group of the C34 side-chain and a regulatory role of the K92, K118, and K130 residues
Keynesian Uncertainty: The Great Divide between Joan Robinson and Paul Samuelson in their Correspondence and Public Exchanges
Joan Robinson and Paul Samuelson found little to agree upon in a correspondence which began in 1946, shortly after the death of Keynes, and ended a year prior to Robinsonâs death in 1983. One way to read the correspondence is to keep in mind that Keynesian uncertainty was central to Robinsonâs understanding of how capitalist economies function. Samuelson, never impressed by Keynesâs handling of uncertainty, understood capital theoryâif not capitalismâin terms of dynamic programming, with its perfect foresight entailments. This is evident throughout his letters to Robinson, although rarely acknowledged in a straightforward way, particularly during the period from 1971 until 1975 when their disagreements came to a head. On several occasions, Robinson despaired of making any progress in getting Samuelson to acknowledge the importance of her questions. Unfailingly polite to her, he granted only in a letter to Solow that, âShe is on to a real problem...
Factors associated with predictors of smoking cessation from a Norwegian internet-based smoking cessation intervention study
Introduction: We examined if we could identify predictors for smoking cessation at six months post cessation, among smokers enrolled in a large Norwegian populationbased intervention study.
Methods: We followed 4333 (72.1% women) smokers who enrolled in an internetbased smoking cessation intervention during 2010â2012. The baseline questionnaire collected information on sociodemographic and lifestyle factors, including current snus use. The cessation outcome was self-reported no smoking past seven days, at six months. We used logistic regression to estimate odds ratios (ORs) with 95% confidence intervals, to identify predictors of smoking cessation, adjusting for potential confounders.
Results: Women (OR=1.30; 95% CI: 1.01â1.69) compared with men, and those with medium (OR=1.31; 95% CI: 1.02â1.68) and longer (OR=1.42; 95% CI: 1.06â1.90) education compared with those with shorter education, were more likely to be successful quitters.
Overall, being a student (OR=0.56; 95% CI: 0.37â0.85) compared with having fulltime work, and a moderate to high FagerstrĂśm test for nicotine dependence (FTND) score (OR=0.69; 95% CI: 0.55â0.87) compared with a low score, were predictors for unsuccessful cessation. Current snus use was a predictor for unsuccessful cessation compared to no snus use for both men (OR=0.49; 95% CI: 0.28â0.88) and women (OR=0.49; 95% CI: 0.32â0.75).
Conclusions: Our study identifies female sex and longer education as predictors for successful smoking cessation, while a medium or high FTND score, being a student, and current snus use, were predictors for unsuccessful smoking cessation. Only current snus use was a predictor for unsuccessful cessation for both sexes. Our results indicate that smokers should be warned that snus use may prevent successful smoking cessation
