HEALTHCARE： A COMPLEX SERVICE SYSTEM

Healthcare is indeed a complex service system, one requiring the technobiology approach of systems engineering to underpin its development as an integrated and adaptive system. In general, healthcare services are carried out with knowledge-intensive agents or components which work together as providers and consumers to create or co-produce value. Indeed, the engineering design of a healthcare system must recognize the fact that it is actually a complex integration of human-centered activities that is increasingly dependent on information technology and knowledge. Like any service system, healthcare can be considered to be a combination or recombination of three essential components — people (characterized by behaviors, values, knowledge, etc.), processes (characterized by collaboration, customization, etc.) and products (characterized by software, hardware, infrastructures, etc.). Thus, a healthcare system is an integrated and adaptive set of people, processes and products. It is, in essence, a system of systems which objectives are to enhance its efficiency (leading to greater interdependency) and effectiveness (leading to improved health). Integration occurs over the physical, temporal, organizational and functional dimensions, while adaptation occurs over the monitoring, feedback, cybernetic and learning dimensions. In sum, such service systems as healthcare are indeed complex, especially due to the uncertainties associated with the human-centered aspects of these systems. Moreover, the system complexities can only be dealt with methods that enhance system integration and adaptation.     

地衣芽孢杆菌营养要求的研究

本文报道了地衣芽孢杆菌的营养要求,结果表明,以葡萄糖为碳源,多种氨基酸为氮源,地衣芽孢杆菌的最佳C/N为4～4．51。满足该菌对维生素H和必须氨基酸的需要以及主要无机盐的需要时,其菌数最高为(3．55～6．7)×107/ml,可使菌数是对照的2．1～3．5倍。

有偿奖励对医生在线健康社区中贡献行为的影响

如何激励用户自愿贡献知识是保持在线社区活跃度的关键。近年来,学者开始探讨有偿激励对在线社区自愿贡献的影响。然而,较少有研究分析多边平台下的有偿激励的溢出效应。借助于自然实验的设计,考虑一种服务主导型在线社区——在线健康社区中,服务提供者(即医生)开通有偿服务(电话咨询)渠道对其知识贡献行为的影响。研究发现：开通有偿服务后,医生会在原来的免费文本咨询服务上也花费更多努力,提供更多、更及时和详实的医疗建议。同时,有偿服务对医生知识贡献的激励作用因医生社交互动程度而不同。相对于社交互动多的医生,社交互动少的医生开通电话咨询后,文本咨询努力程度的增加更明显。以往有关有偿激励对在线社区自愿贡献的影响多基于单边平台中产品主导型激励,该研究将有偿激励拓展至服务主导型的双边平台场景中。采用自然实验的设计,探索有偿激励对自愿贡献的因果关系及异质性,为平台设计和治理提供参考。     

岷江上游干旱河谷辐射松人工幼林营养元素的研究

岷江上游干旱、半干旱河谷5年生辐射松人工幼林的营养元素含量、贮量与分配的研究结果表明:不同立地和气候条件下生长的辐射松人工林,其生长差异较大,营养元素含量与贮量也存在较大差异;树高不同,营养元素含量也有差异;各器官中元素含量以氮最高;由于研究地区土壤富含有效铁,故微量元素铁在乔灌木根系及草本植物中含量极高.辐射松人工幼林营养元素贮量为310.47 kg/hm2,其中乔木层、灌木层、草本层和枯落物层营养元素贮量分别占总贮量的52.25%、15.25%、30.84%和1.66%;分析得知,随生境不同,辐射松人工林乔木层营养元素贮量差异较大.     

The epistemology of hedged laws

Standard objections to the notion of a hedged, or ceteris paribus, law of nature usually boil down to the claim that such laws would be either (1) irredeemably vague, (2) untestable, (3) vacuous, (4) false, or a combination thereof. Using epidemiological studies in nutrition science as an example, I show that this is not true of the hedged law-like generalizations derived from data models used to interpret large and varied sets of empirical observations. Although it may be ‘in principle impossible’ to construct models that explicitly identify all potential causal interferers with the relevant generalization, the view that our failure to do so is fatal to the very notion of a cp-law is plausible only if one illicitly infers metaphysical impossibility from epistemic impossibility. I close with the suggestion that a model-theoretic approach to cp-laws poses a problem for recent attempts to formulate a Mill–Ramsey–Lewis theory of cp-laws.     

运动、营养对免疫机能的影响研究

以现代免疫学和营养学的理论和应用研究为基础,主要对耐力运动、营养健康和免疫机能三者间的关系和相互影响进行了探讨。中等强度运动可增加机体的抗感染能力,而大运动量训练和竞赛可降低机体的免疫力。充足适当的营养是维持正常免疫功能的基础,运动时机体对各种营养素的需求增大,适当补充一些营养素有利于降低运动所致的免疫抑制的发生。     

公立医院医务人员薪酬管理体系改革探讨

公立医院医务人员是医疗服务体系的主体,但是存在收入分配不合理,医务人员职业责任和风险高,工作量大等问题。在医改进程中,保障并提高非营利性公立医院医务人员的薪酬标准,建立新的公立医院薪酬分配体系,是医疗改革问题的根源,也将保障医改顺利进行。
