This study examines how exploiting biases in probability judgment can enhance deterrence using a fixed allocation of defensive resources. We investigate attacker anchoring heuristics for conjunctive events with missing information to distort attacker estimates of success for targets with equal defensive resources. We designed and conducted a behavioral experiment functioning as an analog cyber attack with multiple targets requiring three stages of attack to successfully acquire a target. Each stage is associated with a probability of successfully attacking a layer of defense, reflecting the allocation of resources for each layer. There are four types of targets that have nearly equal likelihood of being successfully attacked, including one type with equally distributed success probabilities over every layer and three types with success probabilities that are concentrated to be lowest in the first, second, or third layer. Players are incentivized by a payoff system that offers a reward for successfully attacked targets and a penalty for failed attacks. We collected data from a total of 1,600 separate target selections from 80 players and discovered that the target type with the lowest probability of success on the first layer was least preferred among attackers, providing the greatest deterrent. Targets with equally distributed success probabilities across layers were the next least preferred among attackers, indicating greater deterrence for uniform-layered defenses compared to defenses that are concentrated at the inner (second or third) levels. This finding is consistent with both attacker anchoring and ambiguity biases and an interpretation of failed attacks as near misses. 相似文献

This article discusses the recognized need for training to support intergenerational engagement. Bridges Together is leading the way in doing so amongst a variety of audiences including teachers, program directors in aging, librarians, mentors, grandparents and more. To establish a network for these audiences to learn, share, and connect; Bridges Together has recently launched a Membership Program so that monthly content can be distributed and individuals can be brought together to network. All of our collaboration aids in intergenerational engagement which is becoming a top priority and an approach to problem-solving within communities, schools, corporations, and families around the world. 相似文献

Online social interaction has become integral to contemporary social life, adding new dimensions to how young people learn, interact, and perceive themselves and one another. This paper presents theoretical insights from a year-long ethnographic study within a Scottish secondary school, where participant observation and qualitative interviews were used to explain pupils’ informal social relationships. Here, pupils aged 11–18 constructed and negotiated a hyper-surveillanced social space within which many became (or strived to become) visible and ‘known’ amongst others and where online presentations of self were highly important. This facilitated a celebrity-esque culture amongst the pupil population whereby pupils learnt from and emulated macro celebrity culture and often framed social interactions as entertainment. Central to these practices, was a continual desire to ‘make gains in distinction’ by demonstrating high social status amongst peers. The paper explores the resulting implications for teaching, learning and pupil wellbeing within contemporary educational environments. 相似文献

This study examines how student perceptions of teacher practices contribute to female high school students’ math beliefs and achievement. Guided by the expectancy–value framework, we hypothesized that students’ motivation beliefs and achievement outcomes in mathematics are fostered by teachers’ emphasis on the relevance of mathematics and constrained by gender‐based differential treatment. To examine these questions, structural equation modeling was applied to a longitudinal panel of 518 female students from the Maryland Adolescent Development in Context Study. While controlling for prior achievement and race, gendered differential treatment was negatively associated with math beliefs and achievement, whereas relevant math instruction was positively associated with these outcomes. These findings suggest inroads that may foster positive math motivational beliefs and achievement among young women. 相似文献

Studies of domestic violence in rural areas have predominantly focused on barriers that keep women trapped in abusive relationships. The literature has frequently suggested that rural culture influences the incidence of domestic violence, the forms it takes, and how it is experienced. Yet there is surprisingly little research on how rural culture plays out in relationships between women and men who experience domestic violence. The study described in this paper explored local culture in a South Australian rural community and how it affected women's experiences of, and men's perpetration of, domestic violence. It found several local cultural discourses that bore on the issue, including self-reliance, pride, privacy, belonging and closeness, family, and Christianity. The power and influence of these discourses made it difficult to name and challenge domestic violence. The paper concludes with the argument that it is important to acknowledge and understand the values and beliefs of rural women and men when developing effective and appropriate responses to rural domestic violence. There is a need to move away from universal understandings of a rural culture to acknowledge discourses that have power and strength within a community so that we can sensitively challenge discourses that silence domestic violence. 相似文献

Why should students and scholars who are interested in gender difference and inequality study organizations? In recent years, as research on organizations has migrated to business schools and become less connected to other subfields of the discipline, the value of organizational sociology has become less evident to many. Yet characteristics of organizations contribute in important ways to producing different experiences and outcomes for women and men, by constraining certain individual actions and enabling or bringing about others. In this essay, we trace the consequences of four categories of organizational characteristics—the formal structure of work, employment practices, informal structure and culture, and organizational networks and fields—for gender inequality in three areas: workplace experiences, work–family conflict, and career outcomes. We close with some brief reflections on future directions for research linking organizations and gender. 相似文献

ABSTRACTThe Social Workers Registration Bill 2018 is before the Parliament of South Australia. It makes provision to establish a social worker registration board with powers to investigate complaints and enforce penalties for breach of competency and ethical standards. This paper presents an argument for the national registration of social workers; and in addition, outlines key considerations for thinking about risk, protection, safeguarding, and implementation that comes with registration.IMPLICATIONS
Risk and protection need to be assessed as part of a more comprehensive regulatory framework in the debates of registration.
If registration is to become part of the regulation of social work, a national approach to social worker registration is indicated, so that a person deregistered in one state cannot be employed as a social worker in another.
Social worker registration is a potentially useful formal mechanism that offers both a protective safeguard (social worker status) and a corrective safeguard (limiting or de-registering).
