救赎：寻求民族文化的出路——解读莫里森的《柏油孩子》

高速铁路具有高度集成、高精度的技术特点，运营过程中经受列车质量、速度、密度等多种因素影响，地理位置因素往往是影响铁路设备状态演变的决定性因素。采用网格化管理技术可将空间上连续分布的管理对象划分成较小的单元网格，有利于从空间位置角度研究管理对象状态的变化规律。随着信息系统技术、大数据技术的迅猛发展，基于位置而不是基于专业更符合高速铁路的管理需求，网格化管理技术给高速铁路管理带来了新的视角。     

Improving Risk Management: From Lame Excuses to Principled Practice

The three classic pillars of risk analysis are risk assessment (how big is the risk and how sure can we be?), risk management (what shall we do about it?), and risk communication (what shall we say about it, to whom, when, and how?). We propose two complements as important parts of these three bases: risk attribution (who or what addressable conditions actually caused an accident or loss?) and learning from experience about risk reduction (what works, and how well?). Failures in complex systems usually evoke blame, often with insufficient attention to root causes of failure, including some aspects of the situation, design decisions, or social norms and culture. Focusing on blame, however, can inhibit effective learning, instead eliciting excuses to deflect attention and perceived culpability. Productive understanding of what went wrong, and how to do better, thus requires moving past recrimination and excuses. This article identifies common blame‐shifting “lame excuses” for poor risk management. These generally contribute little to effective improvements and may leave real risks and preventable causes unaddressed. We propose principles from risk and decision sciences and organizational design to improve results. These start with organizational leadership. More specifically, they include: deliberate testing and learning—especially from near‐misses and accident precursors; careful causal analysis of accidents; risk quantification; candid expression of uncertainties about costs and benefits of risk‐reduction options; optimization of tradeoffs between gathering additional information and immediate action; promotion of safety culture; and mindful allocation of people, responsibilities, and resources to reduce risks. We propose that these principles provide sound foundations for improving successful risk management.     

语文课程素养培养模式的探索与建构——以湛江师范学院中文专业为例

语文课程素养是师范院校中文专业人才培养的综合素养,也是人才培养目标的高度浓缩。"课程整合、平台贯通、操作一体化"培养模式,则是针对当下中文专业人才培养中的问题及素养形成规律提出的具体方案。要使这个方案落实到教学中,既需要教师改变课程观念、确定语文课程素养的培养目标,又要通过教学评价进行引导。而这一方案一旦成为教学中的共识,将大大提高师范院校中文专业的人才培养效率和水平。     

Relationship Quality in Marital and Cohabiting Unions Across Europe

In this study, the authors used data from the first wave of the Generations and Gender Survey to investigate relationship quality among currently married and cohabiting individuals ages 18 to 55 (N = 41,760) in 8 European countries (Bulgaria, France, Germany, Hungary, Norway, Romania, Russia, and The Netherlands). They expected to find fewer differences between cohabitation and marriage in countries where cohabitation is widespread. Controlling for a range of selection characteristics of respondents and their partners (e.g., common children, union duration, and education), the analyses showed that in all countries cohabiters more often had breakup plans and were less satisfied with their relationships than individuals who married. This cohabitation gap in relationship quality was largest in Russia, Romania, and Germany, which indeed were among the countries in the current sample where cohabitation was least prevalent.

Data envelopment analysis in the presence of measurement error: case study from the National Database of Nursing Quality Indicators® (NDNQI®)

Data envelopment analysis (DEA) is the most commonly used approach for evaluating healthcare efficiency [B. Hollingsworth, The measurement of efficiency and productivity of health care delivery. Health Economics 17(10) (2008), pp. 1107–1128], but a long-standing concern is that DEA assumes that data are measured without error. This is quite unlikely, and DEA and other efficiency analysis techniques may yield biased efficiency estimates if it is not realized [B.J. Gajewski, R. Lee, M. Bott, U. Piamjariyakul, and R.L. Taunton, On estimating the distribution of data envelopment analysis efficiency scores: an application to nursing homes’ care planning process. Journal of Applied Statistics 36(9) (2009), pp. 933–944; J. Ruggiero, Data envelopment analysis with stochastic data. Journal of the Operational Research Society 55 (2004), pp. 1008–1012]. We propose to address measurement error systematically using a Bayesian method (Bayesian DEA). We will apply Bayesian DEA to data from the National Database of Nursing Quality Indicators^® to estimate nursing units’ efficiency. Several external reliability studies inform the posterior distribution of the measurement error on the DEA variables. We will discuss the case of generalizing the approach to situations where an external reliability study is not feasible.

摩天时代背景下当代城市建设的反思

摩天大楼成为近年来中国城市建设的重要特征。摩天大楼时代到来的同时，也带来了高楼建筑的社会问题，如安全问题、能原消耗问题、投资风险等。欧洲城市在建造高楼方面，保持了克制与理智的态度，欧洲国家纷纷制定各种法令限制摩天大楼的建设。作为河北省省会城市，2008年开始的“三年大变样”，使石家庄的城市建设步入摩天时代。2012年，石家庄市城乡规划局出台了《石家庄市城市风貌特色管理暂行规定》，石家庄将加强城市风貌特色管理，提高城市品位。人与高楼的和谐共融才是城市建筑存在的重要意义，如此，高楼大厦才会有灵魂，城市才会有未     

Lung Cancer Risk from Radon in Marcellus Shale Gas in Northeast U.S. Homes

The amount of radon in natural gas varies with its source. Little has been published about the radon from shale gas to date, making estimates of its impact on radon‐induced lung cancer speculative. We measured radon in natural gas pipelines carrying gas from the Marcellus Shale in Pennsylvania and West Virginia. Radon concentrations ranged from 1,520 to 2,750 Bq/m³ (41–74 pCi/L), and the throughput‐weighted average was 1,983 Bq/m³ (54 pCi/L). Potential radon exposure due to the use of Marcellus Shale gas for cooking and space heating using vent‐free heaters or gas ranges in northeastern U.S. homes and apartments was assessed. Though the measured radon concentrations are higher than what has been previously reported, it is unlikely that exposure from natural gas cooking would exceed 1.2 Bq/m³ (<1% of the U.S. Environmental Protection Agency's action level). Using worst‐case assumptions, we estimate the excess lifetime (70 years) lung cancer risk associated with cooking to be 1.8×10^?4 (interval spanning 95% of simulation results: 8.5×10^?5, 3.4×10^?4). The risk profile for supplemental heating with unvented gas appliances is similar. Individuals using unvented gas appliances to provide primary heating may face lifetime risks as high as 3.9×10^?3. Under current housing stock and gas consumption assumptions, expected levels of residential radon exposure due to unvented combustion of Marcellus Shale natural gas in the Northeast United States do not result in a detectable change in the lung cancer death rates.
