Donation is a necessary social tool that is plagued by many inherent shortcomings. A novel model in the form of a decentralized app was designed in the Ethereum blockchain to solve the challenges present and optimize the process of Zakaah donation. Load and stress tests on the prototype of the smart contract in the public testnet of Ethereum were analyzed to gauge the feasibility of mass usage. Similar tests were done in Hyperledger to conclude on the optimum blockchain platform for Zakaah. An anomaly was detected during the testing phase of the decentralized app in the public testnet of Ethereum and it was exploited to propose a novel strategy to enhance the throughput of Ethereum. The testing is a pioneer in evaluating the throughput and feasibility of a blockchain based financial product and provides a benchmark to validate the business and technical hypotheses of other similar financial products and services.

Opinion 2/15 addresses the question of the external competence of the EU to conclude a free trade agreement with Singapore (EUSFTA). The nature of the EU’s competence determines the conclusion of an EU-only agreement, or a mixed agreement, jointly by the Union and its Member States. The Court of Justice of the European Union held that the EU competence to conclude the EUSFTA is not exclusive, as long as provisions concerning non-direct investments and dispute settlement fall under the shared competence of the Union and its Member States. The Court of Justice made valuable contributions to the interpretation of the scope of the Union’s competence in the field of common commercial policy, comprising sustainable development provisions, as well as to the interpretation of implied external competences, and clarified the status of non-substantive provisions. However, uncertainty remains as far as the meaning and the impact of a shared competence are concerned. [less ▲]

Context. Metacognitive therapy and one of its treatment components, the attention training technique are increasingly being delivered to improve mental health. Objective. To examine the efficacy of metacognitive therapy and/or attention training technique on mental health outcomes from single-case studies. Methods. Fourteen studies (53 patients) were included. The d-statistic for multiple baseline data and the percentage change index were used to compute the effect sizes. Results. Metacognitive therapy has a large effect on depression, anxiety, other psychopathological symptoms, and all outcomes together. Effect sizes were significantly moderated by the number of sessions, the severity and duration of symptoms, and patient gender, but not by study quality or attention training technique when used as a stand-alone treatment. At the follow-up, 77.36% of the individuals were considered recovered or had maintained improvement. Conclusion. Metacognitive therapy and attention training technique strongly contribute to improving mental health outcomes. This study effectively informs evidence-based practice in the clinical milieu.

The investigation and condition assessment of bridges have a very high priority in the construction industry today. Particularly, due to the fact that many bridge structures are getting old and partly reach the end of their useful life, the control and condition assessment of bridge structures have become very important and essential. The present research work introduces an efficient new method for condition assessment called the Deformation Area Difference (DAD) Method. This new method represents an attractive alternative to visual inspection and long-term monitoring. In this paper, the new method with its theoretical background is presented and explained by means of a laboratory experiment and some additional theoretical calculation examples. The experimental investigations have been realised on a reinforced concrete beam, which has been gradually loaded until failure. For each load step, the stiffness reduction and the apparent cracking have been monitored. High-precision measurements such as close-range photogrammetry, digital levelling and displacement sensors have been used for the determination of the deflection curve. The DAD method has been applied to identify the area of the crack pattern of the laboratory experiment. Furthermore, the method is discussed with regard to the load level and the precision of the deformation measurements. On the basis of the laboratory experiment, the applicability of the DAD method for damage detection could be proven. Furthermore, the sensitivity of the method with regard to the damage degree, the static system, the damage position and the impact of temperature variation were analysed. [less ▲]

Regulator of G-Protein Signaling 4 (RGS4), a member of the RGS family of proteins that inactivate G-proteins, has gained interest as a potential drug target for neurological disorders, such as epilepsy and Parkinson’s disease (PD). In the case of PD, the main current option for alleviating motor symptoms are dopamine replacement therapies, which have limitations because of side effects, and reduced effectiveness over the long term. Research on new non-dopaminergic PD drug targets has indicated that inhibition of RGS4 could be an effective adjuvant treatment option. The effectiveness of RGS4 inhibition for an array of PD-linked functional and structural neuroprotection endpoints has not yet been demonstrated. Here, we use the 6-Hydroxydopamine (6-OHDA) lesioning model of the nigrostriatal pathway in mice to address this question. We observe, using a battery of behavioral and pathological measures, that mice deficient for RGS4 are not protected from 6-OHDA induced injury, and show enhanced susceptibility in some measures of motor function. Our results suggest that inhibition of RGS4 as a non-dopaminergic target for PD should be approached with caution. [less ▲]

Previous studies have almost consistently found differences between lower and higher educated voters regarding their policy congruence, the policy position agreement between voters and their party. This study analyses the role of a campaign herein. Based on novel panel evidence with an extensive battery of policy statements, combined with a survey of party leaders using the same items, we find that, more than the lowly educated, the highly educated profit from the campaign to increase their policy congruence. The reason for the increased inequality is that the later switch parties more often during the campaign than the former. Our evidence also suggests that the higher educated switch parties because this may increase their policy congruence. In sum, the campaign produces a Matthew effect. Those already having a higher policy congruence increase their congruence even further, while those with a lower congruence to start with, do not make any significant progress. [less ▲]

Educational research in Norway has experienced unprecedented structural expansion as well as cognitive shifts over the past two decades, especially due to increased state investments and the strategic use of extensive and multi-year thematic programs to fund research projects. Applying a neo-institutionalist framework, we examine institutionalization dynamics in cultural-cognitive, normative, and regulative dimensions over the past two decades using interviews, research program calls, policy documents, and funding data. In the cultural-cognitive dimension, we find references to the knowledge society, the importance of evidence in policy-making, and ideas of quality, excellence, and relevance. In the normative dimension, we find the introduction of new professional and methodological standards, reflecting broader global patterns of academic and epistemic drift. In the regulative dimension, the strengthened role of both government and the Research Council of Norway is manifest in substantial growth in both funding and large-scale, long-term planning, including thematic choices—evidence of ‘programification’. The importance of external models has grown in an era of internationalization, yet translation occurs at every level of governance of educational research. This results in a specific Norwegian research model, guided by a mode of governance of programs, that maintains social values traditionally strong in Nordic societies. [less ▲]

The recent expansion of Islamic banks raises questions on its economic implications. The aim of this paper is to investigate the impact of Islamic banking development on access to credit. We combine data from a unique hand-collected database that covers Islamic banks with firm-level data covering developing and emerging countries over the period of 2006 to 2009. We find that Islamic banking development has overall no impact on credit constraints, while banking development and conventional banking development alleviate obstacles to financing. However Islamic banking development exerts a positive impact on access to credit when conventional banking development is low. Hence we support the view that Islamic banking does not overall alleviate obstacles to financing, but it can act as substitute to conventional banking. [less ▲]

This presentation focuses on the relationship between the language policy, language ideologies and language practices in a nursery class in trilingual Luxembourg. Individual multilingualism is an educational goal in Luxembourg, a small country in central Europe, and, thus, children learn Luxembourgish from the compulsory nursery school, become literate in German in Year 1 and learn oral and written French from Year 2 and Year 3, respectively. Currently, 62.4% of the children do not speak Luxembourgish on school entry (MENJE 2016). Many speak Portuguese, French or a language of the Balkans. As a result, educational policies focus on the teaching of Luxembourgish from preschool, sometimes at the expense of other languages. Gretsch and Kirsch (2015) developed the app iTEO in order to promote innovative teaching methods that capitalize on the children’s diverse language resources and that promote a dynamic view of bilingualism. This ipad app, which allows for the recording and editing of oral speech, was designed with social-constructivist theories and Bakhtin’s theory of dialogism in mind. This case-study presents the ways in which a preschool teacher’s ideological beliefs influence a child’s language use over a period of two years leading to the child’s understanding of the legitimacy of translanguaging. The focus lies on the interplay between the educational policy focusing on the teaching of Luxembourgish, the teacher’s language ideologies rooted in her multilingual identity and in societal multilingualism, and the child’s experiences of separating languages at home (Kirsch, 2014). The data stem from a qualitative, longitudinal study using a multi-method approach. The study shows that dialogue between teachers, parents, children, policy-makers and researchers can contribute to shifting ideologies and to opening up dynamic languaging spaces. [less ▲]

We study pivotal decomposition schemes and investigate classes of pivotally decomposable operations. We provide sufficient conditions on pivotal operations that guarantee that the corresponding classes of pivotally decomposable operations are clones, and show that under certain assumptions these conditions are also necessary. In the latter case, the pivotal operation together with the constant operations generate the corresponding clone. [less ▲]

This paper examines the extent to which well-being levels change in the transition to retirement depending on transitioning from being employed, unemployed, or economically inactive. Whereas transitioning from employment to unemployment has been found to cause a decrease of subjective well-being with more time spent in unemployment, it is not clear how transitioning from unemployment to retirement affects well-being levels. We use the Survey of Health, Ageing and Retirement in Europe to monitor life satisfaction of respondents who retire in between two waves. We portray well-being scores before and after retirement and then identify the change in life satisfaction during the retirement transition using a First Difference model. Results indicate that being unemployed before retirement is associated with an increase in life satisfaction, but presents mainly a catching-up effect compared to employed persons transitioning to retirement. Retirement from labour market inactivity does not lead to significant changes in well-being. Findings are robust to selection into unemployment and country differences. As well-being of unemployed persons recovers after transitioning to retirement, especially the currently unemployed population should be supported to prevent detrimental consequences of economically unfavourable conditions and lower well-being.
