摘要： Specifications for complex engineering systems are typically decomposed into specifications for individual subsystems in a way that ensures they are imple- mentable and simpler to develop further. We describe a method to algorith- mically construct specifications for components that should implement a given specification when assembled. By eliminating variables that are irrelevant to realizability of each component, we simplify the specifications and reduce the amount of information necessary for operation. To identify these variables, we parametrize the information flow between components. The specifications are written in TLA +, with liveness properties restricted to an implication of conjoined recurrence properties, known as GR(1). We study whether GR(1) contracts exist in the presence of full information, and prove that memoryless GR(1) contracts that preserve safety do not always exist, whereas contracts in GR(1) with history-determined variables added do exist. We observe that timed stutter-invariant specifications of open-systems in general require GR(2) liveness properties for expressing them. We formalize a definition of realizability in TLA +, and define an operator for forming open-systems from closed-systems, based on a variant of the "while- plus" operator. The resulting open-system properties are realizable when ex- pected to be. We compare stepwise implication operators from the litera- ture, and establish relations between them, and examine the arity required for expressing these operators. We examine which symmetric combinations of stepwise implication and implementation kind avoid circular dependence, and show that only Moore components specified by strictly causal stepwise implication avoid circular dependence. The proposed approach relies on symbolic algorithms for computing specifica- tions. To convert the generated specifications from binary decision diagrams to readable formulas over integer variables, we symbolically solve a minimal covering

关键词： Ensemble method   classification   small sample   Euclidian's distance  

摘要： Under certain situations, researchers were forced to work with small sample-sized (SSS) data. With very limited sample size, SSS data have the tendency to undertrain a machine learning algorithm and rendered it ineffective. Some extreme cases in SSS problems will have to deal with large feature-to-instance ratio, where the high number of features compared to small number of instances will overfit the classification algorithm. This paper intends to solve small sample-sized classification problems through hybrid of random subspace method and random linear oracle ensemble by utilizing binary feature subspace splitting and oracle selection scheme. Experimental results on artificial data indicate the proposed algorithm can outperform single decision tree and linear discriminant classifiers in small sample-sized data, but its performance is identical to k-nearest neighbor classifier due to both shared similar selection approach. Results from real-world medical data indicate the proposed method has better classification performance than its corresponding single base classifier especially in the case of decision tree.

关键词： 泰国企业   人民币国际化   国际贸易   计价货币  

摘要： 随着中国与东盟各国的进出口贸易规模日渐增长,到2017年中国与东盟贸易总额达5148.2亿美元,中国也连续九年占领了东盟第一大贸易国的位置。相应的,东盟也连续七年成为中国的第三大贸易伙伴,双方之间的贸易依存度不断攀升,这为人民币国际化的健康发展提供了良好的前提条件。特别是在2016年10月1日,人民币被国际货币基金组织(IMF)正式纳入“特别提款权货币篮子”,这大大提升了各国在国际贸易中选择人民币作为计价货币的可能性。作为东盟成员国,泰国是中国在东盟国家中第三大贸易伙伴国,中国也是泰国的第二大贸易伙伴国。目前泰国企业在进行国际贸易结算时,主要采用第三国货币作为计价货币,其中美元是最主要的国际贸易结算计价货币。在中泰贸易关系日益密切,中国―一带一路‖战略实施,及国家层面不断推进人民币国际化的背景下,本文从泰国企业的角度尝试回答以下问题:当前的泰国进出口企业会更大范围地使用人民币作为计价货币吗?哪些因素会影响到泰国企业在国际贸易中计价货币的选择?影响泰国企业使用人民币作为国际贸易计价货币的因素又有哪些?人民币若要成为中泰贸易中主要的计价货币目前还存在哪些方面的问题?本文在前人研究的基础上,本文尝试以市场份额、产品差异化程度、经济实力和货币实力四项因素构建分析模型,借助调查问卷的方式,最终收回有效问卷182份。在整理调查问卷数据结果的基础上,对泰国企业在国际贸易中决定计价货币的影响因素进行深入分析,同时分析了样本企业对人民币作为计价货币的态度,梳理总结了泰国企业使用人民币作为计价货币的影响因素,以此来分析目前人民币是否满足企业选择计价货币的要求,同时寻找推进人民币作为国际计价货币的突破点,为人民币在泰国的计价和使用提出对策建议。最终研究发现,样本企业更偏好使用美元,其次是泰铢,接着才是人民币。国际贸易中,影响泰国企业使用人民币计价的主要微观因素是泰国企业自身所占的市场份额和宏观因素人民币的货币实力。在泰国企业选择货币进行结算的趋势上,虽然人民币作为国际结算货币还存在缺点,但未来人民币在中泰贸易以及泰国与其他国家贸易中作为结算货币有上升的趋势。

摘要： Disease advocacy organizations (DAOs) have traditionally focused on raising awareness of rare diseases, providing educational resources to patients, and supporting patients and families. Previous research has described how scientists collaborate with DAOs, but few empirical data are available regarding the extent to which physicians interact with DAOs and how those interactions impact patient care. We conducted a national survey of 230 board-certified pediatric neurologists to assess their engagement with DAOs and their beliefs about the impact of DAOs on patient care. In that context, we evaluated a set of 24 items describing interactions between physicians and DAOs. Exploratory factor analysis produced a 19-item model capturing four types of physician–DAO engagement: (1) accessing or distributing DAO-produced materials (6 items, alpha = 0.80); (2) consulting on DAO activities (5 items, alpha = 0.81); (3) collaborating with DAOs on research activities (6 items, alpha = 0.80); and (4) co-producing scholarly materials with DAOs (2 items, alpha = 0.80). Our data indicate that physicians engage with DAOs in more frequent and diverse ways than has been previously reported. Almost all physicians in our sample had interacted directly with a DAO in some way, from low-effort activities such as visiting a DAO’s website to deeper forms of engagement including coauthoring journal articles. These findings may provide a framework for bioethicists to characterize the nature and extent of physician interactions with advocacy organizations, which is critical for evaluating the ethical implications of physician–DAO relationships. © 2019, © 2019 Taylor & Francis Group, LLC.

摘要： The purpose of this quantitative research was to assess the effects of modeling, practice, and reflection on teachers’ technology self-efficacy when implemented in a structured technology professional development session. Technology is a highly researched topic in education and researchers have proven that when used effectively, technology will increase student engagement (Günüç & Kuzu, 2014). However, the lack of technology integration by educators continues to be an issue in the educational setting (Jones, 2012). The lack of technology integration relates to the professional development methods deployed to teachers (Canela, 2013). A practical suggestion for technology professional development requires strategically incorporating the Technological Pedagogical Knowledge (TPK) domains of Technological Pedagogical and Content Knowledge (TPACK) and a modified version of the Technology Learning Cycle (TLC) model to facilitate the learning process for effective technology integration. A random-assigned sample of 40 sixth to eighth-grade middle school teachers participated in the study with half participating in structured technology professional development and the other half will remain the control group. Analysis of a pretest and posttest survey provides campus and district leadership with insight on the effectiveness of a technology professional development plan. The recommendations of this study include implementation of TPK based activities within a modified TLC professional development session to address educators’ technology self-efficacy.
