TL;DR: A new reputation system for data credibility assessment based on the blockchain techniques that is reliable in collecting, validating, and storing reputation information in vehicular networks is proposed.
Abstract: The security of vehicular networks has been paid increasing attention to with the rapid development of automobile industry and Internet of Things (IoT). However, existing approaches mainly focus on ensuring data authentication and integrity, which are not sufficient to assess the credibility of received messages. Recently, reputation systems are proved to be effective approaches to solve the above problem. This paper proposes a new reputation system for data credibility assessment based on the blockchain techniques. In this system, vehicles rate the received messages based on observations of traffic environments and pack these ratings into a “block”. Each block is “chained” to the previous one by storing the hash value of the previous block. Then, a temporary center node is elected from vehicles and it is responsible for broadcasting its rating block to others. Based on ratings stored in the blockchain, vehicles are able to calculate the reputation value of the message sender and then evaluate the credibility of the message. Simulation results reveal that the proposed system is reliable in collecting, validating, and storing reputation information in vehicular networks.

TL;DR: How feedback is handled within different professional cultures, and how the characteristics and values of a profession shape learners' responses to feedback are explored.
Abstract: Context Although feedback is widely considered essential to learning, its actual influence on learners is variable. Research on responsivity to feedback has tended to focus on individual rather than social or cultural influences on learning. In this study, we explored how feedback is handled within different professional cultures, and how the characteristics and values of a profession shape learners' responses to feedback. Methods Using a constructivist grounded theory approach, we conducted 12 focus groups and nine individual interviews (with a total of 50 participants) across three cultures of professional training in, respectively, music, teacher training and medicine. Constant comparative analysis for recurring themes was conducted iteratively. Results Each of the three professional cultures created a distinct context for learning that influenced how feedback was handled. Despite these contextual differences, credibility and constructiveness emerged as critical constants, identified by learners across cultures as essential for feedback to be perceived as meaningful. However, the definitions of credibility and constructiveness were distinct to each professional culture and the cultures varied considerably in how effectively they supported the occurrence of feedback with these critical characteristics. Conclusions Professions define credibility and constructiveness in culturally specific ways and create contexts for learning that may either facilitate or constrain the provision of meaningful feedback. Comparison with other professional cultures may offer strategies for creating a productive feedback culture within medical education.

TL;DR: This article developed and tested several new hypotheses about the anti-inflationary effect of central bank independence and exchange rate pegs in the context of different institutions and different degrees of citizen information about government policies.
Abstract: The authors develop and test several new hypotheses about the anti-inflationary effect of central bank independence and exchange rate pegs in the context of different institutions and different degrees of citizen information about government policies. Theory provides strong reason to believe that while central bank independence will prove more effective as a commitment mechanism in countries where multiple players in government have veto power (checks and balances), the number of veto players will have no effect on the credibility of exchange rate pegs. Conversely, the authors argue that central bank independence does not solve the problems of commitment that arise when citizens are imperfectly informed about the contribution of government policy to inflation. Exchange rate pegs, however, mitigate these problems. The authors present extensive evidence from cross-country tests using newly developed data that provide strong support for their propositions.

TL;DR: This paper explored the practice of credibility assessment in lower level tribunals using a case study of over 1000 particular social group ground (PSG) decisions made on the basis of sexual orientation over the past 15 years.
Abstract: Credibility assessment has always been a major issue in refugee determinations and its importance increases in the context of widespread introduction of 'fast-track' processes and the manifest trans-national trend to truncate (or indeed remove) avenues for review. This article explores the practice of credibility assessment in lower level tribunals using a case study of over 1000 particular social group ground (PSG) decisions made on the basis of sexual orientation over the past 15 years. Credibility played an increasingly major role in claim refusals, and negative credibility assessments were not always based on well-reasoned or defensible grounds. The article uses this specific case study in order to ground recommendations for structural and institutional change aimed at improving the credibility assessment process in refugee determinations more broadly.
