摘要： Understanding the impact of human behavior on the spread of disease is critical in mitigating outbreak severity. We designed an experimental game that emulated worker decision-making in a swine facility during an outbreak. In order to combat contamination, the simulation features a line-of-separation biosecurity protocol. Participants are provided disease severity information and can choose whether or not to comply with a shower protocol. Each simulated decision carried the potential for either an economic cost or an opportunity cost, both of which affected their potential real-world earnings. Participants must weigh the risk infection vs. an opportunity cost associated with compliance. Participants then completed a multiple price list (MPL) risk assessment survey. The survey uses a context-free, paired-lottery approach in which one of two options may be selected, with varying probabilities of a high and low risk payouts. We compared game response data to MPL risk assessment. Game risk was calculated using the normalized frequency of biosecurity compliance. Three predominant strategies were identified: risk averse participants who had the highest rate of compliance;risk tolerant participants who had the lowest compliance rate;and opportunists who adapted their strategy depending on disease risk. These findings were compared to the proportion of risk averse choices observed within the MPL and were classified into 3 categories: risk averse, risk tolerant and neutral. We found weak positive correlation between risk measured in our experimental game compared to the MPL. However, risk averse classified participants in the MPL tended to comply with the biosecurity protocol more often than those classified as risk tolerant. We also found that the behavioral risk clusters and categorization via the MPL were significantly, yet weakly associated. Overall, behavioral distributions were skewed toward more risk averse choices in both the MPL and game. However, the MPL risk asses

摘要： An existing undergraduate computer science curriculum was augmented with activities that address diversity, equity, and inclusion (DEI) in the discipline and associated professions. The effort was part of a larger project (Partnership for Equity:STEM) that seeks to cultivate inclusive professional identities in engineering and computer science students through curricular design. The development and implementation of such a curricular activity, used successfully in introductory computer science courses, is described along with qualitative analyses of student responses. The experience also revealed that inherent differences among institutions and across disciplines represent significant impediments to the transferability of curricular activities and the conduct of research in broader contexts.

摘要： Dependency management in modern software development poses many challenges for developers who wish to stay up to date with the latest features and fixes whilst ensuring backwards compatibility. Project maintainers have opted for varied, and sometimes conflicting, approaches for maintaining their dependencies. Opting for unsuitable approaches can introduce bugs and vulnerabilities into the project, introduce breaking changes, cause extraneous installations, and reduce dependency understandability, making it harder for others to contribute effectively. In this paper, we empirically examine evidence of recurring dependency management issues (dependency smells). We look at the commit data for a dataset of 1,146 active JavaScript repositories to catalog, quantify and understand dependency smells. Through a series of surveys with practitioners, we identify and quantify seven dependency smells with varying degrees of popularity and investigate why they are introduced throughout project history. Our findings indicate that dependency smells are prevalent in JavaScript projects with two or more distinct smells appearing in 80 percent of the projects, but they generally infect a minority of a project's dependencies. Our observations show that the number of dependency smells tend to increase over time. Practitioners agree that dependency smells bring about many problems including security threats, bugs, dependency breakage, runtime errors, and other maintenance issues. These smells are generally introduced as developers react to dependency misbehaviour and the shortcomings of the npm ecosystem.

关键词： 中国乡村   互动仪式   公共性   宗教生活   道德价值  

摘要： 面对社会发展的道德间隙期,19世纪涂尔干以宗教研究解释道德的起源与变迁,认为仪式活动使道德的“纪律精神”“依恋精神”“自决精神”得以强化,社会运转所依托的物质制度与行动规约得以延续,社会整合也依之加强。据此分析中国乡土社会,贯穿于乡民日常的生产、政治、教化、生活和娱乐等多方面的互动仪式在社会秩序维持、社会结构整合、社会行动牵引上发挥着重要作用。而面对现代性的冲击,中国传统互动仪式面临着空间压缩、价值偏离、规则拆解、主体阻隔的环境转变,其公共性塑造功能逐渐衰弱。对此,必须从空间拓展、价值革新、渠道疏通以及载体优化等方面调整互动仪式的生成环境,推进乡村社会治理内在动能的重生。
