The citizensâ perspective : awareness, feelings and acceptance of surveillance and surveillance systems for fighting crime in Austria. A quantitative study
This document presents the results for Austria within the framework of a larger study undertaken as part of the RESPECT project â âRules, Expectations and Security through Privacy-enhanced Convenient Technologiesâ (RESPECT; G.A. 285582) â which was co-financed by the European Commission within the Seventh Framework Programme (2007-2013). Analyses are based on a survey regarding the perceptions, feelings, attitudes and behaviours of citizens towards surveillance for the purpose of fighting crime, carried out amongst a quota sample that is representative of the population in Austria for age and gender. Responses were gathered, predominantly, through an online survey supplemented by a number of questionnaires administered in face to face interviews, in order to fulfil the quota and also reach those citizens who do not use the internet. The questionnaire consisted of 50 questions and was available online in all languages of the European Union between November 2013 and March 2014. The face to face interviews were carried out between January and March 2014. The sample is based on the responses from 135 individuals who indicated Austria as their country of residence in the online survey or were administered the questionnaire face to face. As a result, the Austrian respondents overall felt more insecure than secure in the presence of surveillance, and they indicated a strongly felt lack of trust in the protection of, and control over, personal information gathered via surveillance. Further, the majority of respondents also feel more unhappy than happy with the different types of surveillance investigated, and they feel also unhappy about surveillance taking place without them knowing about it. Additionally, there is a link between feeling happy, or unhappy, about surveillance and feeling secure or insecure through the presence of surveillance. However, analyses also indicate that increasing the perceived effectiveness of surveillance measures and, in particular, increasing the perceived effectiveness of laws regarding the protection of personal data gathered via surveillance may make citizens feel more secure. More research is needed to disentangle the relationships and effects between surveillance measures, feelings of security or insecurity, and citizensâ general quality of life feelings.This project has received funding from the European Unionâs Seventh Framework Programme for research, technological development and demonstration under grant agreement no 285582.peer-reviewe
gLCB: An Energy Aware Context Broker
Context
Worldwide mobile device sales will reach 821 Million units in 2012 and will rise to 1.2 Billion in 2013. Inevitably the paradigm for access information and Internet services is increasingly migrating to mobile. Context-aware services can help to improve the user experience because they can adapt themselves to the usersâ context but, despite the improvements in terms of hardware, the the main obstacle towards a widespread adoption of such services is the limited battery life. A context-aware service requires the installation of a Context-Broker Application, which generates a continuous flow of data from the smartphone and a constant usage of its equipped sensors: as a consequence the considerable increase of energy consumption becomes a problem.
Aim
The aim of this work is to propose gLCB an Energy Efficient Context-Aware middleware for Android OS, which is able to collect Context Information and to send it to a remote platform in an energy-efficient way. The gLCB application proposes a new energy-aware data collection based on user profiles.
Methods
We define policies based on battery consumption profiles, which are selected depending on modifications of the context information. Moreover, we have implemented an automatic consumption testing mechanism and a statistical treatment of results to provide a reliable validation of gLCB in terms of energy efficiency.
Results
Experimental results show that our middleware got the best trade-off between number of server uploads and battery lifetime with the policies computed automatically by the device. This means that the way in which software is written can impact the energy consumption of a mobile device and service adaptation can be based on the actual value of the battery charge
The role of emotional resilience, childhood parentification, and attachment style on antisocial behaviour in adulthood: a comparison of an offender and normative population
Purpose: Despite a robust link between poor caregiver attachment and antisociality, few studies have examined the influence of parentification and emotional resilience on delinquency in later life, in groups at differing risk for antisocial conduct.
Methodology: This pilot study compared the influence of parentification, attachment style (avoidant or anxious) and emotional resilience on adulthood antisocial behaviour in an offender and normative sample. Of the 137 participants in this study, 66 were supervised by the National Probation Service (age M = 36.90, SD = 13.91), and 71 were recruited from community-dwelling and student populations (age M = 31.83, SD = 13.25).
Findings: In partial support of the predictions, participants in the offender group reported significantly greater levels of attachment anxiety compared to the normative group. However, emotional resilience was positively associated with antisociality in the normative sample.
Research implications: This small-scale investigation indicates value in exploring these specific variables in a larger, matched samples study, to enable clearer comparisons to be made between offender and normative groups.
Practical implications: The preliminary findings suggest that attachment anxiety is associated with antisociality in offender populations, which indicate a therapeutic focus on attachment anxiety as part of correctional care and offender rehabilitation.
Originality: This study is novel in its aim to examine the influence of childhood parentification, attachment deficits and emotional resilience on adulthood antisociality in participants from a high-risk offender sample and non-high-risk normative sample
Great Aunt Edna's vase: metaphor use in working with heritage language families
This article explores the use of a particular metaphorâGreat Aunt Ednaâs Vaseâas a means to facilitating multilingual families in contextualizing and engaging with complex emotional connections as linked to language, identity, and belonging. Building from the premise that language is linked to the construction of identity, but that individual family members will have different views and opinions on the heritage language within this context, this article highlights the use of metaphors in family work, before introducing the metaphor of Great Aunt Ednaâs Vase and situating it in relevant literature around language, heritage, and identity. The concepts introduced add to the existing body of literature in addressing the growing need for work specifically aimed at multilingual families, in a globally ever-more-diverse society, highlighting the links between language and well-being, and making a contribution to the global knowledge necessary for practitioners and families to explore these links successfully
A bacterially-expressed recombinant envelope protein from Usutu virus induces neutralizing antibodies in rabbits
Background: Recently, an emerging flavivirus, Usutu virus (USUV), has caused an epidemic among birds in Europe, resulting in a massive die-off in Eurasian blackbirds. Currently found only in Europe and Africa, it can be envisioned that Usutu virus will follow the path of other flaviviruses, like West Nile virus and Zika virus, and will spread via its mosquito vectors and bird hosts to other parts of the world. Several cases of human infections by Usutu virus have already been published. Anticipating this spread, development of an efficacious vaccine would be highly desirable. Method: This study describes the production in E. coli, purification, and refolding of a partial USUV envelope protein. Prior to immunization, the protein was characterized using size exclusion chromatography, transmission electron microscopy and dynamic light scattering, showing the limited presence of virus-like structures, indicating that the protein solution is probably a mixture of mono and multimeric envelope proteins. Results: Immunizations of two rabbits with the refolded E-protein fraction, mixed with a strong adjuvant, resulted in the generation of neutralizing antibodies, as evidenced in an in vitro assay. Discussion: The way forward towards a subunit vaccine against Usutu virus infection is discussed.Microscopic imaging and technolog
Immunogenicity and efficacy of one and two doses of Ad26.COV2.S COVID vaccine in adult and aged NHP
Safe and effective coronavirus disease-19 (COVID-19) vaccines are urgently needed to control the ongoing pandemic. While single-dose vaccine regimens would provide multiple advantages, two doses may improve the magnitude and durability of immunity and protective efficacy. We assessed one-and two-dose regimens of the Ad26.COV2.S vaccine candidate in adult and aged nonhuman primates (NHPs). A two-dose Ad26.COV2.S regimen induced higher peak binding and neutralizing antibody responses compared with a single dose. In one-dose regimens, neutralizing antibody responses were stable for at least 14 wk, providing an early indication of durability. Ad26.COV2.S induced humoral immunity and T helper cell (Th cell) 1-skewed cellular responses in aged NHPs that were comparable to those in adult animals. Aged Ad26.COV2.S-vaccinated animals challenged 3 mo after dose 1 with a SARS-CoV-2 spike G614 variant showed near complete lower and substantial upper respiratory tract protection for both regimens. Neutralization of variants of concern by NHP sera was reduced for B.1.351 lineages while maintained for the B.1.1.7 lineage independent of Ad26.COV2.S vaccine regimen.Molecular basis of virus replication, viral pathogenesis and antiviral strategie
