Protection vs. Privacy: Exploring Motivational Factors Shaping Individuals´ Information Security Behaviors on Mobile and Social Media Platforms
A thesis submitted in partial fulfillment of the requirements for the degree of Doctor in Information Management, specialization in Information TechnologiesThis thesis investigates the intertwined dynamics of data protection and privacy in the realm of information security, focusing on two critical issues: mobile identity protection against theft attacks and the privacy implications of personalization in social media.
This research aims to unravel the role of motivation, specifically drawing on concepts from self-efficacy, protection motivation theory, and expectancy-value theory. The overarching goal is to enhance our comprehension of individual intentions and actions concerning mobile identity protection and responses to privacy intrusiveness of personalized content on social media.
The methodology employed encompasses a systematic literature review followed by two mixed-methods studies for mobile identity protection, exploring threat appraisal, protection experience, self-efficacy, and motivation values. For the privacy intrusion issue in personalization, two survey studies and one multiple quantitative study are conducted, focusing on psychological mechanisms and cognitive responses that mediate the relationship between perceived privacy personalization and engagement.
The key findings underscore the significant impact of threat appraisal, protection experience, and self-efficacy in shaping motivational intentions and actual protection of mobile identities. Additionally, the existence of an expectancy-capability gap is revealed, with motivation values and awareness playing crucial roles in bridging this gap. In the context of social media personalization, the research unveils the intricate interplay of psychological mechanisms and cognitive responses, shedding light on the paradoxical effects of personalization and transparency on individuals' engagement.
The major contribution of this work lies in advancing our understanding of the motivational factors influencing information security behaviors. It not only identifies key determinants but also uncovers nuanced relationships, such as the mediation role of awareness and psychological mechanisms in the mobile environment and the defensive responses and coping behaviors against the personalization paradox in social media. This research provides valuable insights that contribute to the theoretical foundations of information security, offering practical implications for designing effective interventions and strategies to enhance individuals' protection and privacy in the digital age
THE IMPACT OF ONLINE ADVERTISMENT PERSONALIZATION AND TRANSPARENCY ON INDIVIDUAL DEFENSIVE RESPONSES AND ENGAGMENT
This study identifies the different individual defensive responses that are triggered by ad personalization. We investigate how these responses impact user engagement behavior on social media. The study also examines the role of transparency in advertising and the perceived benefits of personalization on user engagement in Europe. To conduct our study, we are theoretically grounded in the defensive response model. A multi-step quantitative approach constituting two experiments and a survey is used. With 154 and 199 participants each, the experiments allowed us to define the theoretical model. The experiment identified paradoxical findings. We indent surveying online ads-users to examine the impact of personalization on individual defensive responses and the role transparency plays in predicting user engagement. Our research contributes to the theory by identifying defensive responses that explain the engagement behavior, and the impact of transparency on personalized advertising

The Moderation Role of Self-Efficacy
Al Helaly, Y., Dhillon, G., & Oliveira, T. (2024). Mobile Identity Protection: The Moderation Role of Self-Efficacy. Australasian Journal of Information Systems, 28, 1-40. https://doi.org/10.3127/ajis.v28.4397 --- The authors would like to thank Fundação para a Ciência e a Tecnologia (FCT) regarding the program UIDB/04152/2020 - Centro de Investigação em Gestão de Informação — MagIC (NOVA IMS).The rapid growth of mobile applications and the associated increased dependency on digital identity raises the growing risk of identity theft and related fraud. Hence, protecting identity in a mobile environment is a problem. This study develops a model that examines the role of identity protection self-efficacy in increasing users’ motivation intentions to achieve actual mobile identity protection. Our research found that self-efficacy significantly affects the relationship between users’ perceived threat appraisal and their motivational intentions for identity protection. The relation between mobile users’ protection, motivational intentions, and actual mobile identity protection actions was also found to be significant. Additionally, the findings revealed the considerable impact of awareness in fully mediating between self-efficacy and actual identity protection. The model and its hypotheses are empirically tested through a survey of 383 mobile users, and the findings are validated through a panel of experts, thus confirming the impact of self-efficacy on an individual’s identity protection in the mobile context.publishersversionpublishe
Pancreatic surgery outcomes: multicentre prospective snapshot study in 67 countries
Background: Pancreatic surgery remains associated with high morbidity rates. Although postoperative mortality appears to have improved with specialization, the outcomes reported in the literature reflect the activity of highly specialized centres. The aim of this study was to evaluate the outcomes following pancreatic surgery worldwide.Methods: This was an international, prospective, multicentre, cross-sectional snapshot study of consecutive patients undergoing pancreatic operations worldwide in a 3-month interval in 2021. The primary outcome was postoperative mortality within 90 days of surgery. Multivariable logistic regression was used to explore relationships with Human Development Index (HDI) and other parameters.Results: A total of 4223 patients from 67 countries were analysed. A complication of any severity was detected in 68.7 percent of patients (2901 of 4223). Major complication rates (Clavien-Dindo grade at least IIIa) were 24, 18, and 27 percent, and mortality rates were 10, 5, and 5 per cent in low-to-middle-, high-, and very high-HDI countries respectively. The 90-day postoperative mortality rate was 5.4 per cent (229 of 4223) overall, but was significantly higher in the low-to-middle-HDI group (adjusted OR 2.88, 95 per cent c.i. 1.80 to 4.48). The overall failure-to-rescue rate was 21 percent; however, it was 41 per cent in low-to-middle-compared with 19 per cent in very high-HDI countries.Conclusion: Excess mortality in low-to-middle-HDI countries could be attributable to failure to rescue of patients from severe complications. The authors call for a collaborative response from international and regional associations of pancreatic surgeons to address management related to death from postoperative complications to tackle the global disparities in the outcomes of pancreatic surgery (NCT04652271; ISRCTN95140761)
