Predicting Teens' Privacy Management and Attitude Toward Data Protection on Social Media.

This study contributes to ongoing debates on the protection of teens' privacy on social media. While ample research is focused on teens' privacy management, less is known about their attitude toward data protection. Drawing from cross-sectional survey data, this study examines whether predictors of privacy management, namely privacy literacy, privacy concern, and perceptions of data control, also predict teens' attitude toward data protection. Structural equation modeling indicates that all three factors positively predict this facet of privacy. No significant differences were found in the strength of predictors for boys versus girls for privacy management, although the findings do suggest some gender differences for attitude toward data protection that call for further research.

Applying contextual integrity to digital contact tracing and automated triage for hospitals during COVID-19.

To control and minimise the spread of COVID-19, various technological solutions have been proposed. In this research, we focus on digital contact tracing and automated triage for hospitals. We conducted an online survey in Flanders (N = 1708) to investigate the perceived appropriateness of these systems based on the Contextual Integrity framework, as developed by Nissenbaum [1]. For digital contact tracing, significant differences were found between the appropriateness of using various types of data for different goals. Precise individual location data (i.e. GPS) was considered to be least appropriate and much less appropriate than proximity data (i.e. Bluetooth) or coarser location data (i.e. GSM). Goals for digital contact tracing with a high individual impact were considered to be less appropriate than goals with a low individual or societal impact. In addition, the data showed that respondents would find the usage of digital contact tracing to be less appropriate after the pandemic, underlining the temporality of this technological solution. For automated triage, the results indicated that gender is perceived to be significantly less appropriate than the other types of data, including age, to determine the priority of treatment.

Covid-19 and tracing methodologies: A lesson for the future society.

As the new coronavirus (SARS-CoV-2) surged across the globe, new technical solutions have supported policy makers and health authorities to plan and modulate containment measures. The introduction of these solutions provoked a large debate which has focused on risks for privacy and data protection. In this paper we offer an analysis of the available technical approaches and provide new arguments to move beyond the ongoing discussions. In particular, we argue that the past debate missed the opportunity to highlight the societal aspects of privacy and to stimulate a broader reflection on the actions needed to serve the good of society. With this paper, as well as providing an accessible review of the technical and legal aspects of the proposed solutions, we aim to offer new stimuli to reconsider contact tracing and its role in helping countries navigate the current pandemic.

Concise report: Teenage sexting on the rise? Results of a cohort study using a weighted sample of adolescents.

Background The vast differences in sampling techniques, cultural contexts between international studies, the differences in age groups of the samples and various definitions used to measure sexting make it hard to compare how sexting behaviour has evolved over the past years. This exploratory study aims to address this critical gap in the research by using two datasets of a biennial study on adolescents' media use. The first aim of this study is to compare the sexting prevalence and correlates (i.e. age, gender and smartphone ownership) of youth in 2015 and 2017. The second aim is to investigate the risk mitigation behaviours of youth who engage in sexting and to assess how their behaviours differ between the two time points. METHODS: The data for cohort 1 were collected in October and November 2015 and comprise of 2663 students from 11 secondary schools in the Dutch-speaking community of Belgium. For the second cohort, the data were collected in October and November 2017 and comprise of 2681 students from 10 secondary schools. A weighing factor was implemented on the dataset. RESULTS: The results show sexting behaviour has significantly increased between cohorts, with 8.3% of the respondents having sent a sext in the first cohort, compared with 12.1% in the second cohort. The sexting prevalence rates also significantly increased between cohorts when taking into account students who owned a smartphone. Furthermore, engagement in sexting was associated with being older, and no gender differences were found. In the second cohort, 36.8% of youth who had sent a sext were identifiable in those images. There were no differences between cohorts. CONCLUSION: The results indicate that other factors next to smartphone ownership may be associated with an increase in sexting prevalence. The findings also highlight the need for the development of age-appropriate sexting educational materials.

[Patient Groups with Different Risk Profiles for Irregular Drop-Out from Forensic Psychiatry (§â€Š64 StGB)]. / Patientengruppen mit unterschiedlichem Risikoprofil für eine vorzeitige Erledigung des Maßregelvollzugs (§â€Š64 StGB).

OBJECTIVE: About 50 - 70 % of the patients with substance abuse disorders who are mandated to forensic treatment according to the section 64 of the German penal code are discharged from treatment irregularly. Previous research identified a number of potential risk factors for irregular treatment dropout. Systematic assessment of risks factors and their consideration for treatment planning may help to improve treatment retention. Therefore, the aim of this study was to identify groups of patients with a comparable risk profile for treatment dropout. METHODS: From 2007 - 2012, patients entering forensic treatment completed the MATE-Crimi and a sociodemographic questionnaire. RESULTS: From 431 patients entering forensic treatment, 357 patients agreed to participate. Of the 357 included patients 35.9 % had completed the forensic treatment irregular. Using cox regression, young age, low treatment motivation and a primary criminal behaviour with the substance use as a consequence of criminal behaviour were identified as risk factors for early drop-out. A subsequent analysis of latent classes using these variables resulted in three classes. CONCLUSIONS: Our study revealed a small number of risk factors being relevant for treatment drop-out. Furthermore, we identified three groups of patients with different risk profiles. Next steps include the development of treatment pathways for these patient groups.

A prosthodontic technique to improve the simplicity and the efficacy of angled abutments for divergent implant situations: a technical note.

Esthetic demands and nonparallel situations between the axial direction of the suprastructure and the implant require angulation of the abutment. The Conical Seal design avoids microleakage and micromovements after the abutment has been seated and finally retained via screw. However, there is no protection against rotation during the fixation procedure. Therefore, a control device and/or method for a reproduction of correct seating during each treatment step of permanent prosthesis fabrication is desirable. The purpose of this investigation was to develop a device to ensure the correct seating by less expensive, safer, easier, and more precise methods. The sequence of components and the standard procedure required modification: in the modified procedure, the impression is made at the implant level, and the straight implant replica is embedded in the laboratory cast. The angled abutment needs modification by grinding to create small margins in the mesial, distal, and palatal walls. Three materials that are used in daily dental practice are combined to fabricate an individual transfer device. Direct waxup of the restoration onto the angled abutment without a prefabricated component shortens the laboratory processing. The modified sequence and procedure, small alterations of the angled abutment, and an individual transfer device can simplify the transfer procedures, improve clinical performance and applicability, and shorten chair time.
