Attack Taxonomy for Cyber-Physical System

Cyber-physical systems are the systems that combine the physical world with the world of information processing. CPS involves interaction between heterogeneous components that include electronic chips, software systems, sensors and actuators. It makes the CPS vulnerable to attacks. How to deal with the attacks in CPSs has become a research hotspot. In this paper we have study the Architecture of CPS and various security threats at each layer of the archicture of CPS. We have also developed attack taxonomy for CPS. Keywords: Cyber Physical System, Threat, Attack

What is the relationship between people with dementia and their caregiver’s illness perceptions post-diagnosis and the impact on help-seeking behaviour? A systematic review

Background: As the number of people with dementia increases, more families will be affected by the daily challenges of providing effective support, given its current incurable status. Once individuals are diagnosed with dementia, the earlier they access support, the more effective the outcome. However, once people receive a diagnosis, how they make sense of their dementia can impact on their help-seeking intentions. Exploring the illness beliefs of people with dementia and their caregivers and this relationship to help seeking may identify how best to facilitate early support. Aims: To systematically obtain and critically review relevant studies on the relationship between illness perceptions and help seeking of people with dementia and their caregivers. Method: A systematic search was conducted and included both quantitative and qualitative studies. The initial search was conducted in October 2018, with an adjacent search conducted in April 2020. Findings: A total of 14 articles met the inclusion criteria. Conceptually, the studies examined the association of illness perceptions and help-seeking post-diagnosis and revealed that people living with dementia and their caregivers sought help when symptoms became severe. Components of illness perceptions revealed that lack of knowledge, cultural beliefs, complexity of the healthcare system, threat to independence and acceptance were identified as major factors for delaying help seeking. Conclusion: Although research interest in the area of illness perceptions and their impact on help seeking for dementia is increasing, further work is needed to understand this area, particularly regarding the influence of the relationship between the person with dementia and their caregiver.

System Threat during a Pandemic: How Conspiracy Theories Help to Justify the System

During the COVID-19 pandemic, many people have endorsed conspiracy theories about foreign governments yet shown increased trust and support for their own government. Whether there is a potential correlation between these social phenomena and the psychological mechanisms behind them is still unclear. Integrating insights from the existential threat model of conspiracy theories and system justification theory, two experimental studies were conducted to investigate whether belief in out-group conspiracy theories can play a mediating role in the effects of system threat on people's system justification beliefs against the background of the pandemic. The results show that system threat positively predicts individuals’ system-justifying belief, and belief in out-group conspiracy theories mediated this relationship.

The Effects of Gender Trouble: An Integrative Theoretical Framework of the Perpetuation and Disruption of the Gender/Sex Binary

In the Western world, gender has traditionally been viewed in the Western world as binary and as following directly from biological sex. This view is slowly changing among both experts and the general public, a change that has been met with strong opposition. In this article, we explore the psychological processes underlying these dynamics. Drawing on previous work on gender performativity as well as gender as a performance, we develop a psychological framework of the perpetuation and disruption of the gender/sex binary on a stage that facilitates and foregrounds binary gender/sex performance. Whenever character, costume, and script are not aligned the gender/sex binary is disrupted and gender trouble ensues. We integrate various strands of the psychological literature into this framework and explain the processes underlying these reactions. We propose that gender trouble can elicit threat—personal threat, group-based and identity threat, and system threat—which in turn leads to efforts to alleviate this threat through the reinforcement of the gender/sex binary. Our framework challenges the way psychologists have traditionally treated gender/sex in theory and empirical work and proposes new avenues and implications for future research.

Sexism, perceived discrimination, and system justification in the 2016 U.S. presidential election context

The 2016 U.S. presidential election provided a pertinent context for investigating novel influences on system-related beliefs. We examined Trump and Clinton supporters’ sexist attitudes toward women, perceptions of gender discrimination, and system justification before and after the election. Controlling for conservatism, we found that (a) Trump supporters reported more modern and hostile sexism than Clinton supporters; (b) male Trump supporters perceived greater gender discrimination toward men than male Clinton supporters, an effect mediated by sexist attitudes toward women; (c) female Trump supporters perceived less gender discrimination toward women than female Clinton supporters, an effect also mediated by sexist attitudes toward women; and (d) system justification increased among Trump supporters but decreased among Clinton supporters postelection. These results extend the existing literature on system-related beliefs by revealing the role of antifeminism and misogyny in shaping perceptions of gender discrimination and highlighting how political outcomes are associated with system threat versus reinforcement.

Parliaments in Time

This book sheds light on the institutional development of four (emerging) Western European parliaments. Parliaments in Western Europe are noteworthy for several reasons. Their institutional designs differ remarkably, with distinct consequences for their policy output. Scholars have diagnosed the decline of legislatures for over a century now. Based on a model of distributive bargaining over legislative procedures, this book engages in a comparative process-tracing analysis of ninety reforms, which restructured control over the plenary agenda and committee power in Britain, France, Sweden, and Germany between 1866 and 2015. The analysis presented suggests that legislators in Western Europe rationalize procedures as a response to growing levels of legislative workload. As a consequence, legislatures evolve towards one of two procedural ideal types: talking or working legislatures. In talking legislatures, governments enjoy privileges in legislative agenda-setting (resulting in centralized agenda control) and committees are weak. In contrast, working legislatures combine decentralized agenda control with powerful committees. Which path legislators chose is determined by the appearance of anti-system obstruction. If anti-system parties obstruct legislative business, legislators surrender ancient procedural privileges and agree to a centralization of agenda control. Otherwise, their demand for legislative mega-seats on committees triggers the evolution of working legislatures. If legislators fail to respond to an anti-system threat, legislative procedures break down. For this reason, the central aim of procedural reforms in Western European parliaments is to maintain legislative democracy. Rather than a decline of legislatures, for talking legislatures to successfully overcome an anti-system threat indicates the resilience of legislative democracy.

Pathways to Path-Dependence, 1918–90

During 1918–90 ideological, anti-system communist and fascist parties emerged. Anti-system obstruction and the response to it from establishment parties explain why a centralization of agenda control succeeded in the French National Assembly in 1958 but not during previous reform attempts or in the German Reichstag during the Weimar Republic. The absence of obstruction (in the French case) or legislators’ procedural response to it (in the German case) prevented any substantial reform in the interwar years. Only when anti-system obstruction triggered a procedural response did the centralization of agenda control succeed in France. Once procedural path changes occurred, legislators adapted by developing a preference for talk (in the plenary) or work (in committees). This explains why neither the disappearance of the anti-system threat in the British House of Commons nor the emergence of a Communist party in the Swedish Riksdag affected the respective procedural paths chosen prior to 1917.
