This article provides a multi-disciplinary overview of the contemporary cybercrime ecosystem and its developments. It does so by reviewing and synthesising recent cybercrime research from fields such as cybersecurity, law and criminology. The article also examines ways in which gaps between the aforementioned fields arise and how to lessen them to increase cybersecurity. This article is divided into four main parts. The first part offers background on cybercrime and some of its main elements. It defines terminology, sets out a legal taxonomy of cybercrime offences and presents the estimated costs, threat agents and characteristics of various illicit activities and technical aspects of cybercrime. Parts two, three and four build on this preceding analysis by (separately) examining three prominent threat vectors within the ecosystem – malware, the darknet and Bitcoin and other cryptocurrencies. For each threat vector, the article identifies and investigates features, history, functions and current and expected states of development within the ecosystem. Through its attention to and synthesis of current research and results from different fields, this article offers a synoptic account of the cybercrime ecosystem, which can bridge potential knowledge gaps between fields.  相似文献

Increasingly severe wildfires have focused attention on forested watershed vulnerabilities, causing significant changes to policies and governance. We utilized the Multiple Streams Approach (MSA) to understand institutional innovations of federal agency–large water provider partnerships in Colorado to protect watersheds through joint planning and funding. Ambiguous problem definition and focusing events were significant aspects of these partnerships. We interviewed individuals in the partnerships, with MSA ideas of how solutions to policy problems develop, and the role of policy entrepreneurs. We found that wildfires served as focusing events, creating space and time for learning, collaboration and new problem framing, increased political attention, and institutional innovation. In this study, windows of opportunity stayed open longer, policy entrepreneurs and agencies played larger roles in communication and coupling streams and the context of fast‐moving, unpredictable ecological crises changed responses to issues. Our findings also have implications for broader policy studies and environmental governance scholarship.  相似文献

This article provides a three-step process for analyzing public policy dilemmas with ethical implications. A framework is proposed that builds on existing ethics theories and attempts to provide a relevant, usable approach for decisionmaking. A review of current thought in ethics indicates a concern for two areas: (a) responsibilities to relevant constituencies; and (b) adherence to moral obligations. The framework presented herein directly addresses both of these areas of concern. The authors have found this approach to be useful for classroom applications. This process is simple to explain, understand, and apply to a range of administrative situations. Students find the framework a memorable tool, useful in structuring deliberations with ethical implications. Sample applications of the framework provide examples for educators interested in integrating ethics into their advanced undergraduate and graduate courses.  相似文献

Public education is a sphere of society in which distributive justice with respect to the allocation of opportunities to learn can have profound and lasting effects on students’ educational outcomes. We frame our study in the distributive justice literature, and define just outcomes specifically from a meritocratic and strict egalitarian perspectives in order to investigate how assignment to academic tracks and the availability of opportunities to learn during high school are associated with students’ academic achievement during college. We examine the role of “just” placement into high school academic tracks, “just” access to high-quality teachers, and “just” assignment of secondary schools’ resources in high school, in relation to college freshmen’s grade point averages (GPA). We utilize longitudinal data from a unique dataset with over 15,000 students who spent their academic careers in North Carolina public secondary schools and then attended North Carolina public universities. Our results suggest that “unjust” assignment of students to certain high schools, access to high-quality teachers, and assignment to learn in specific academic tracks result in long-lasting consequences that are reflected in freshman college GPA. Importantly, findings also show that the direction and magnitude of the relationship between distributional injustice at schools and college performance is moderated by students’ own gender and race. Race and gender interact with the high schools’ institutional contexts operationalized by tracking practices, teacher quality, and by school racial and socioeconomic composition. Results show that similar settings do not affect all students in the same ways.  相似文献

Using difference‐in‐difference and difference‐in‐difference‐in‐difference designs, we study California's Paid Family Leave (CA‐PFL) program, the first source of government‐provided paid parental leave available to fathers in the Unites States. Relative to the pre‐treatment mean, fathers of infants in California are 46 percent more likely to be on leave when CA‐PFL is available. In households where both parents work, we find suggestive evidence that CA‐PFL increases both father‐only leave‐taking (i.e., father on leave while mother is at work) and joint leave‐taking (i.e., both parents on leave at the same time). Effects are larger for fathers of first‐born children than for fathers of later‐born children.  相似文献
