VANET safety applications broadcast cooperative awareness messages (CAM) periodically to provide vehicles with continuous updates about the surrounding traffic. The periodicity and the spatiotemporal information contained in these messages allow a global adversary to track vehicle movements. Many privacy schemes have been proposed for VANET, but only few schemes consider their impact on safety applications. Also, each scheme is evaluated using inconsistent metrics and unrealistic vehicle traces, which makes comparing the actual performance of different schemes in the wild more difficult. In this paper, we aim to fill this gap and compare different privacy schemes not only in terms of the privacy gained but also their impact on safety applications. A distortion-based privacy metric is initially proposed and compared with other popular privacy metrics showing its effectiveness in measuring privacy. A practical safety metric which is based on Monte Carlo analysis is then proposed to measure the QoS of two safety applications: forward collision warning and lane change warning. Using realistic vehicle traces, six state-of-the-art VANET privacy schemes are evaluated and compared in terms of the proposed privacy and safety metrics. Among the evaluated schemes, it was found that the coordinated silent period scheme achieves the best privacy and QoS levels but fully synchronized silence among all vehicles is a practical challenge. The CAPS and CADS schemes provide a practical compromise between privacy and safety since they employ only the necessary silence periods to prevent tracking and avoid changing pseudonyms in trivial situations.

A gradual decline in functional and mental capacity as well as a growing risk of care dependency constitute major concerns of life in old age. These should become larger and more urgent in future, because the number of people 80+ is projected to more than double from 2010 to 2050 at least in EU and OECD countries. On the other side, there is a strong desire of older people, their relatives and policy makers to maintain the autonomy in old age as long as possible. In reaction to this, there have been strong social policy recommendations to develop and promote the use of assistive technologies (ATs). Whereas systematic reviews already exist for several other kinds of ATs, reviews about self-care ATs are still missing. Based on systematic literature searches in PsycINFO, MEDLINE, and Google Scholar databases 203 papers were identified of which 12 were included according to our selection criteria. The methodological quality of all the reviewed studies is evaluated. We reviewed findings on indicators of independent living as efficiency criteria as well as evidence about facilitators and barriers of using these technologies. Self-care ATs turned out to be efficient with respect to reduced care hours and increased independence level. The actual use of these ATs was associated with personal, contextual, and device factors. Lack of randomized control trial studies and a need for further research about ATs in several domains of self-care activities is revealed. Based on the findings of the current review, we generate recommendations for future research. [less ▲]

Care for elderly persons is multifaceted and embedded in a rich socio-ecological context of individual, micro-, and macro-social factors. This complexity requires multidisciplinary perspectives to better understand phenomena of elder care and to act successfully in this field. In the final chapter of a multidisciplinary book with contributions from geropsychology, other gerosciences, and cultural psychology the editors draw conclusions about major topics, new insights, and further implications for research and practice. The conclusions refer to four domains. First, the macro-social context—including demographic, historical, political, normative, and other cultural factors—opens and limits the available options for individual care giving and receipt and shapes how these issues are experienced by the participants. Second, elder care at the individual and family level is far more complex than previously thought, due to differentiated individual and social care preferences and due to consequences extending beyond single caregivers to multigenerational caring families. Third, processes involved in formal and informal care turned out to be rather differentiated: Understanding, emotional responding, motivation and acting towards suffering, care dependency and caregiver burden are influenced by multiple individual and social level factors. Fourth, future issues of elder care are shaped by macro level factors such as population aging, social trends in job and family life, and technological developments with implications for ensuring care quality, care staff, culturally sensitive care, and assistive technologies. Cultural psychology emerged as a valuable partner of the gerosciences by contributing essentially to a deeper understanding of the aforementioned issues. [less ▲]

In the introduction of a multidisciplinary book on the role of culture in elder care the editors set the stage for a substantive integration of contributions from geropsychology, other gerosciences, and cultural psychology. The authors present arguments for a life-span developmental perspective on care for the elderly and extend this to geropsychology as subsection of life-span developmental psychology. They further emphasize that these disciplines consider to some extent the role of cultural and other contextual factors and that other gerosciences specialized on historical, political, health-and nursing-related aspects of elder care can further supplement this effort. Then three major streams of cultural psychology are mentioned which are particularly relevant to topics of caring: Dialogical Self Theory, Theory of Social Representations, and Cultural Psychology of Semiotic Dynamics. The authors conclude that an increasing population aging and growing gaps between demand and supply of care create a serious practical need for an integration of geropsychology, other gerosciences, and cultural psychologies to achieve a better understanding of the individual, interpersonal, and macro social processes involved in elder care.

This commentary responds to Aarseth et al.’s (in press) criticisms that the ICD-11 Gaming Disorder proposal would result in “moral panics around the harm of video gaming” and “the treatment of abundant false-positive cases.” The ICD-11 Gaming Disorder avoids potential “overpathologizing” with its explicit reference to functional impairment caused by gaming and therefore improves upon a number of flawed previous approaches to identifying cases with suspected gaming-related harms. We contend that moral panics are more likely to occur and be exacerbated by misinformation and lack of understanding, rather than proceed from having a clear diagnostic system [less ▲]

In this chapter, we analyze scientific and legal concepts of care dependency and explore their roles for understanding, emotional responding, and acting of various participants in the field of elder care. First, two comprehensive concepts from the nursing sciences are contrasted. Then we compare a scientific and two legal concepts (restrictive vs. inclusive) of care dependency from the German long-term care (LTC) system, the last of which regulate older persons´ access to LTC benefits. Here, we consider their different implications for the risk of unmet psychological, social, and temporary care needs. Next, we examine the theoretical and methodological roles of different care dependency concepts for assessment as well as the analysis of prevalence, antecedents, consequences, and the management of care dependency. Following this, we explore possible functions of care dependency concepts as cognitive mediators of various agents’ activities related to elder care, which opens new topics for further research. Among these, we include the ascription of care dependency by various actors, older people´s self-presentation, and family carers´ presentation and LTC administrators´ evaluation of an older person´s care dependency. Further issues addressed are the education of professional care workers and professionals´ provision of elder care. Here, special attention is devoted to the implications of a shift from a restrictive to a more inclusive legal concept of care dependency as recently happened in Germany. Finally, we discuss the implications of inclusive legal concepts of care dependency for the improvement of elder care quality [less ▲]

This paper studies convergence of credit structure worldwide. We hand-collect data on credit to household and firm credit for 143 countries over the period 1995-2014. First, we separately document the existence of a convergence process of total credit, household credit and firm credit, respectively. Second, we find that convergence of household credit occurs faster than firm credit, inducing a process of convergence of the share of household credit to total credit. Third, convergence occurs faster in low-income countries and in countries with a lower initial level of total credit but slows down after the 2008 global financial crisis. Finally, our data investigation does not support the idea that convergence is driven by changing conditions in developing countries. [less ▲]

Background and aims: Binge-watching (i.e., seeing multiple episodes of the same TV series in a row) now constitutes a widespread phenomenon. However, little is known about the psychological factors underlying this behavior, as reflected by the paucity of available studies, most merely focusing on its potential harmfulness by applying the classic criteria used for other addictive disorders without exploring the uniqueness of binge-watching. The present study thus aimed to take the opposite approach as a first step toward a genuine understanding of binge-watching behaviors through a qualitative analysis of the phenomenological characteristics of TV series watching. Methods: A focus group of regular TV series viewers (N=7) was established to explore a wide range of aspects related to TV series watching (e.g., motives, viewing practices, related behaviors). Results: A content analysis identified bingewatching features across three dimensions: TV series watching motivations, TV series watching engagement, and structural characteristics of TV shows. Most participants acknowledged that TV series watching can become addictive, but they all agreed having trouble recognizing themselves as truly being an “addict.” Although obvious connections could be established with substance addiction criteria and symptoms, such parallelism appeared to be insufficient, as several distinctive facets emerged (e.g., positive view, transient overinvolvement, context dependency, low everyday life impact). Discussion and conclusions: Research should go beyond the classic biomedical and psychological models of addictive behaviors to account for binge-watching in order to explore its specificities and generate first steps toward an adequate theoretical rationale for these emerging problematic behaviors.

Why drama of multilingualism? Who cares about it? The book starts with a vignette on the (mis)understandings of the kindergarten situation around strawberries. By this vignette, I introduce different levels of power relations between children, parents and teachers around language use. I then use Nancy Hornberger’s (1989) Continua of Biliteracy model through which I broaden this vignette and describe the structure of the book: why I chose to deal with this subject, what is my approach, why I conducted the interviews and discussion with the experts and their students in the US and how I plan to integrate this into something novel worth reading. Through the interaction with the experts on the topic I had during the interviews I focus on several topics: the necessity of defining and theorising in a specific social context, power relations, language policy, linguistic creativity and criticality, support for multilingual identity, gap in research. I conclude by underlining the notion of whether there is more or less drama in this field and who cares about it. [less ▲]
