Online communities use trust and reputation systems to assist their users in evaluating other parties. Due to the preponderance of these systems, malicious entities have a strong incentive to attempt to influence them, and strategies employed are increasingly sophisticated. Current practice is to evaluate trust and reputation systems against known attacks, and hence are heavily reliant on expert analysts. We present a novel method for automatically identifying vulnerabilities in such systems by formulating the problem as a derivative-free optimisation problem and applying efficient sampling methods. We illustrate the application of this method for attacks that involve the injection of false evidence, and identify vulnerabilities in existing trust models. In this way, we provide reliable and objective means to assess how robust trust and reputation systems are to different kinds of attacks.

Software-defined networks (SDNs) have become a mechanism to separate the control plane and the data plane in the communication in networks. SDNs involve several challenges around their security and their confidentiality. Ideally, SDNs should incorporate autonomous and adaptive systems for controlling the routing to be able to isolate network resources that may be malfunctioning or whose security has been compromised with malware. The current work introduces a novel agent-based framework that simulates SDN isolation protocols by means of trust and reputation models. This way, SDN programmers may estimate the repercussions of certain isolation protocols based on trust models before actually deploying the protocol into the network.

Oleh sebab itu, penelitian ini mengajukan suatu klasifikasi model kepercayaan interpersonal pada keberlanjutan pengelolaan organisasi Papermoon Puppet Theatre. Sembilan orang narasumber diwawancarai untuk mendapatkan informasi terkait topik penelitian tersebut. Hasilnya menunjukkan terdapat kepercayaan internal dan eksternal organisasi. Terdapat tiga aspek penting yang harus diberdayakan dalam membangun kepercayaan, yaitu seniman, kesenian, dan masyarakat. How to build the trust of a performing arts organization?

The performing arts organizations tend not to pay attention to the aspect of trust, the organization focuses more on the work. Therefore, this study proposes a classification of interpersonal trust models on the sustainability of the Papermoon Puppet Theater organization. Nine resource persons were interviewed for information related to the research topic. The results show there are internal and external organizational confidence. There are three important aspects that must be empowered in building trust, namely artists, art, and society.

Abstract. LGBT-related hate crime is a conscious act of aggression against an LGBT citizen. The present research investigates associations between hate crime, psychological well-being, trust in the police and intentions to report future experiences of hate crime. A survey study was conducted among 391 LGBT respondents in the Netherlands. Sixteen percent experienced hate crime in the 12 months prior. Compared to non-victims, victims had significant lower psychological well-being, lower trust in the police and lower intentions to report future hate crime. Hate crime experience and lower psychological well-being were associated with lower reporting intentions through lower trust in the police. Helping hate crime victims cope with psychological distress in combination with building trust in the police could positively influence future reporting.

Companies are organised to fulfil two distinctive functions: efficient and resilient exploitation of current business and parallel exploration of new possibilities. For the latter, companies require strong organisational infrastructure such as team compositions and functional structures to ensure exploration remains effective. This paper explores the potential for designing organisational infrastructure to be part of fourth order subject matter. In particular, it explores how organisational infrastructure could be designed in the context of an exploratory unit, operating in a large heritage airline. This paper leverages insights from a long-term action research project and finds that building trust and shared frames are crucial to designing infrastructure that affords the greater explorative agenda of an organisation.
