Provincial governments retain an essentially unrestricted jurisdictional autonomy as regards the structuring and coordination of post-secondary education (PSE) systems. It is at the provincial level that crucial balances must be struck between the competing demands placed on costly PSE systems. This article develops a comparative historical analysis of the British Columbia and Ontario cases in this relatively neglected area of provincial public management. Strong path-dependent logics are identified in both cases, anchored in interconnected networks of institutional and local interests. Current developments in both provinces are assessed against the background of these longer-term historical patterns and in relation to wider international trends. [less ▲]

To cost-effectively test embedded software, practitioners and researchers have proposed many test techniques, approaches, tools, and frameworks. However, obtaining an overview of the state of the art and state of the practice in this area is challenging for practitioners or new researchers. In addition, owing to an inadequate overview of what already exists in this area, some companies often reinvent the wheel by designing a test approach that’s new to them but already exists. To address these problems, the authors conducted a systematic literature review of this area that covered the testing topics, testing activities, test artifacts, and industries on which the studies focused. The results can benefit both practitioners and researchers by serving as an index to the vast body of knowledge in this important, fast-growing area. [less ▲]

Visual GUI testing (VGT) is a tool-driven technique, which uses image recognition for interaction and assertion of the behaviour of system under test. Motivated by a real industrial need, in the context of a large Turkish software and systems company providing solutions in the areas of defense and IT sector, we systematically planned and applied a VGT project in this industrial context. The goal of the initial phase of the project was to empirically evaluate two well-known VGT tools (Sikuli and JAutomate) to help the company select the best tool for a given testing project. Our results show that both two tools suffer from similar test ‘Replay’ problems such as the inability to find smaller-sized images. The repeatability of test executions was better for JAutomate in case of one of the two software under test (SUT) while it was comparable for the other. In terms of test development effort, for both tools, there were high correlations with number of steps in test suites, however the effort is reduced if test code is reused. The study has already provided benefits to the test engineers and managers in the company by increasing the know-how in the company w.r.t. VGT, and by identifying the challenges and their workarounds in using the tools. The industrial case study in this paper intends to add to the body of evidence in VGT and help other researchers and practitioners. [less ▲]

Need for Cognition (NFC) is increasingly being investigated in educational research. In contrast to other non-cognitive constructs in this area, such as academic self-concept and interest, NFC has consistently been conceptualized as domain-general. We employed structural equation modelling to address the question of whether NFC can be meaningfully and gainfully conceptualized as domain-specific. To this end, we developed a domain-specific 20-item NFC scale with parallel items for Science, Mathematics, German, and French. Additionally, domain-general NFC was assessed with five domain-general items. Using a cross-sectional sample of more than 4500 Luxembourgish 9th graders, we found that a nested-factor model incorporating both a general factor and domain-specific factors better accounted for the data than a single- factor or a correlated-factor model. However, the influence of the general factor was markedly stronger than in corresponding models for academic self-concept and interest. When controlling for the domain-specific factors, only Mathematics achievement was significantly predicted by the domain-general factor, while all achievement measures (Mathematics, French, and German) were predicted by the corresponding domain-specific factor. The nested domain-specific NFC factors were clearly empirically distinguishable from first-order domain-specific interest factors. [less ▲]

Motivated by a real-world industrial need in the context of a large IT solutions company based in Turkey, the authors and their colleagues developed and introduced automated test suites for GUI testing of two large-scale law-practice management software (comprising of 414 and 105 KLOC). We report in this paper our experience in developing and introducing a set of large automated test suites (more than 50 KLOC in total), using best practices in state-of-the art and –practice, and to report its observed benefits by conducting cost-benefit analysis in the specific industrial context. The project was conducted based on the principles of case-study and “action research” in which the real industrial needs drove the research. Among the best practices that we used are the followings: (1) the page-object test pattern, (2) modularity in test code, (3) creating test-specific libraries, and (4) using systematic guidelines to decide when and what (test cases) to automate. To assess the cost-benefit and Return On Investment (ROI) of test automation, we followed a hybrid measurement approach to assess both the quantitative and qualitative (intangible) benefits of test automation. The empirical findings showed that the automated GUI testing approach has indeed benefitted the test and QA team in the company under study and automation has been highly welcome by the test engineers. By serving as a success story and experience report in development and introduction of automated test suites in an industrial setting, this paper adds to the body of evidence in this area and it aims at sharing both technical (e.g., using automated test patterns) and process aspects (e.g., test process improvement) of our project with other practitioners and researchers with the hope of encouraging more industry-academia collaborations in test automation.

The mitochondrial proteins TRAP1 and HtrA2 have previously been shown to be phosphorylated in the presence of the Parkinson’s disease kinase PINK1 but the downstream signaling is unclear. HtrA2 and PINK1 loss of function causes parkinsonism in humans and animals. Here, we identified TRAP1 as an interactor of HtrA2 using an unbiased mass spectrometry approach. In our human cell models, TRAP1 overexpression is protective, rescuing HtrA2 and PINK1-associated mitochondrial dysfunction and suggesting that TRAP1 acts downstream of HtrA2 and PINK1. HtrA2 regulates TRAP1 protein levels, but TRAP1 is not a direct target of HtrA2 protease activity. Following genetic screening of Parkinson’s disease patients and healthy controls, we also report the first TRAP1 mutation leading to complete loss of functional protein in a patient with late onset Parkinson’s disease. Analysis of fibroblasts derived from the patient reveal that oxygen consumption, ATP output and reactive oxygen species are increased compared to healthy individuals. This is coupled with an increased pool of free NADH, increased mitochondrial biogenesis, triggering of the mitochondrial unfolded protein response, loss of mitochondrial membrane potential and sensitivity to mitochondrial removal and apoptosis. These data highlight the role of TRAP1 in the regulation of energy metabolism and mitochondrial quality control. Interestingly, the diabetes drug metformin reverses mutation-associated alterations on energy metabolism, mitochondrial biogenesis and restores mitochondrial membrane potential. In summary, our data show that TRAP1 acts downstream of PINK1 and HtrA2 for mitochondrial fine tuning, whereas TRAP1 loss of function leads to reduced control of energy metabolism, ultimately impacting mitochondrial membrane potential. These findings offer new insight into mitochondrial pathologies in Parkinson’s disease and provide new prospects for targeted therapies. [less ▲]

Testing and fixing WAFs are two relevant and complementary challenges for security analysts. Automated testing helps to cost-effectively detect vulnerabilities in a WAF by generating effective test cases, i.e., attacks. Once vulnerabilities have been identified, the WAF needs to be fixed by augmenting its rule set to filter attacks without blocking legitimate requests. However, existing research suggests that rule sets are very difficult to understand and too complex to be manually fixed. In this paper, we formalise the problem of fixing vulnerable WAFs as a combinatorial optimisation problem. To solve it, we propose an automated approach that combines machine learning with multi-objective genetic algorithms. Given a set of legitimate requests and bypassing SQL injection attacks, our approach automatically infers regular expressions that, when added to the WAF's rule set, prevent many attacks while letting legitimate requests go through. Our empirical evaluation based on both open-source and proprietary WAFs shows that the generated filter rules are effective at blocking previously identified and successful SQL injection attacks (recall between 54.6% and 98.3%), while triggering in most cases no or few false positives (false positive rate between 0% and 2%).

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 ▲]
