Performance Effects Related to the Sequence of Integration of Healthcare Technologies

There is a natural order to most events in life: Everything from learning to read to DNA sequences in molecular biology follows some predetermined, structured methodology that has been refined to yield improved results. Likewise, it would seem that firms could benefit by adopting and implementing technologies in some logical way so as to increase their overall performance. In this study of 555 hospitals, we investigate the order in which medical technologies are transformed into information technologies through a process of converting them from stand‐alone technologies to interoperable, integrated information systems and whether certain configurations of sequences of integration yield additional value. We find that sequence does matter and that hospitals that integrated foundational technologies first—which in this case are known to be more complex—tend to perform better. Theoretical and practical implications of this finding and others are discussed.     

社会救援资源动员联盟伙伴选择

社会救援资源是应急救援工作的重要资源支撑,平时被企业、非政府组织和社会公众等各类社会主体所掌控。动员联盟则是各类主体所组建的特殊虚拟企业。动员联盟的特殊性表现为无准备期、联盟盟主往往多线程、弱经济性以及时效性和高动态性,其组织形式应为星型联邦模式。伙伴选择则是组建动员联盟的关键问题,直接关系到救援成效。社会救援资源动员联盟伙伴选择包括正序选择与逆序选择两种方式,每种方式都适合不同的条件,并有不同的步骤且各有其合理算法。     

《朗读者》:凿向多元叙述的利斧——小说叙事艺术探微

德国作家本哈德·施林克的《朗读者》,以精致、独到的小说艺术赢得一致好评。其在文本叙事方面的主要特征是:镶嵌并置的多重故事叙事,时间颠倒的时序倒置,隐喻与深层结构下的宗教话语言说;这些策略的运用,将小说的叙述艺术以多元的方式呈现了出来。     

基于移动平均模型对上海未来空气质量的定量评估

对2010年上海世博会相关重大事件活动效应进行估算有着十分重大的现实意义,其中部分问题的提出及解决方案对现实中的环境保护起着指导作用.以时间序列预测法的移动平均模型为依据,在对其进行改造的基础上,用通行的Excel程序包进行统计分析,实现了对世博会环境效应的定量评估.     

及物性过程的一致性和序列性——超越词汇层的衔接现象

传统的衔接分析往往基于词汇层,如词的指称、替代等,是从微观角度出发的分析,达不到反映整个语篇的结构关系。从系统功能语言学来看,任何语篇的过程类型都是有章可循的,并且是构建语篇的框架。本文通过对语篇实例进行及物性过程分析,发现语篇衔接也反映在小句及物性过程类型上,并可归纳为两种主要的衔接方式:及物性过程一致式、及物性过程序列式。对及物性过程进行的衔接分析超越了词汇层,是一种宏观的分析方法,它有助于读者把握全篇信息的分布走向,并对写作过程中的谋篇布局起到积极的指导作用。      

Distributions of statistics describing concentration of runs in non homogeneous Markov-dependent trials

In the first n, n ? 3, trials of a non homogeneous zero-one Markov chain of first order, we consider runs of ones of length exceeding a threshold. The article deals with statistics denoting, the length and the position of the shortest segment of the chain in which all such runs of ones are concentrated. The study provides recursive schemes for conditional distributions of these statistics. Numerical examples illustrate the theoretical results.     

Generalized neighbor designs with block size 3

A generalized neighbor design relaxes the equality condition on the number of times two treatments as neighbors in the design. In this article, we have considered the construction of some classes of generalized neighbor designs with block size k=3 by using the method of cyclic shifts. The distinguishing feature of this construction method is that the properties of a design can easily be obtained from the sets of shifts instead of constructing the actual blocks of the design. A catalog of generalized neighbor designs with block size k=3 is compiled for v∈{5,6,…,18} treatments and for different replications. We provide the reader with a simpler method of construction, and in general the catalog that gives an open choice to the experimenter for selecting any class of neighbor designs.     

“数量＋动＂与“动＋数量＂构式的不对称性解析

“动＋数量”和“数量＋动”构式同为现代汉语动量的表达方式,但两者的地位和功能并非等值,“动＋数量”构式是动量的基本表达方式,其表述功能单一,一般只位于句末表述动作的客观量,而“数量＋动”构式则是具有一定语用功能的有标记性表达,具有凸显动作情状、表达主观量以及充当句子话题焦点和次话题的功能。汉语动量语序的历时选择过程是造成“动＋数量’’和“数量＋动”构式不对称的根本原因。     

印尼J区块层序地层与沉积相特征研究

利用层序地层学理论,对印尼J区块古近系—新近系的层序地层和沉积相特征进行了研究。古近系—新近系可以分为7个中期基准面旋回（SQ1SQ7）和17个短期基准面旋回。SQ1SQ7沉积时期,沉积环境从陆相河流环境逐渐过渡到三角洲环境和浅海环境,再到河流环境,为一完整的水进-水退旋回。中下部层序上升旋回占主体,属海进式沉积组合序列;上部层序下降旋回占主体,多为海退式沉积组合序列。结合层序特征,指出区块西部凸起带SQ5旋回的浊积砂体、基底风化壳、碳酸盐岩台地和东部斜坡带的下切谷为区块的有利勘探区带。研究结果对该盆地的石油勘探具有指导意义。     

“民工荒”现象成因及对策分析

从去年下半年开始出现的“民工荒”打破了我国劳动力“无限供给”的神话,对我国未来经济增长产生了不容忽视的影响。本文对“民工荒”之所以出现作了原因分析,认为当前宏观经济形势和新的二元社会结构是导致“民工荒”的深层次原因,并对此提出了相应的对策。
