用荧光微球-流式细胞术检测流行性出血热的初步研究

发展了一种应用荧光微球进行流行性出血热流式细胞术检测的新方法。方法为先在荧光微球表面连接上流行性出血热特定的抗体以及相应的抗原等物质,然后,通过TEM(透射电子显微镜)和流式细胞仪等技术对实验结果进行了表征和解释。方法的进一步研究正在进行中。

五台山旅游景观偏好特征——基于游记照片色彩表征的分析

旅游景观偏好特征与目的地选择决策直接相关,收集马蜂窝旅游网五台山相关旅游照片,采用色彩分析技术,形成11种色彩与景观的对应关系,运用社会网络分析法,划分旅游者景观偏好的核心/边缘部分.结果显示,五台山旅游景观偏好呈现明显的层次结构,可以分为三个层次:以"古朴"为基底的聚焦类景观群,以"小清新"为基底的喜爱类景观群,以"多彩"为基底的偏爱类景观群.据此,提出五台山旅游营销建议.     

Social work and applied theatre: creative experiences with a group of homeless people in the city of Seville

This article presents a series of creative social intervention experiences developed with a group of homeless people in the Spanish city of Seville. These experiences are part of an applied research project that uses theatre as a tool to aid social work, and they are led by a group of homeless people who have become actors through this initiative. The group is known as ‘Theatre of Inclusion’ and has been running for a decade now. Using group social work and applied theatre techniques, this initiative creatively exposes the needs of this collective and also generates spaces in which they can reclaim their dignity. The systematisation of these experiences highlights the potential of combining disciplines such as social work and theatre to work with vulnerable collectives, in the same way Jane Addams did. The aim is also to move beyond the dominant welfare proposals in place in Spain currently, which are intended to meet the needs of homeless people.     

“THE WAR FOR THE FARE”: HOW DRIVER COMPENSATION AFFECTS BUS SYSTEM PERFORMANCE

Prior to 2007, two systems of bus driver compensation coexisted in Santiago, Chile: one paid drivers per passenger transported, while the other paid a fixed wage. Per‐passenger drivers engaged in “The War for the Fare,” altering their driving patterns to compete for passengers. Examining these systems on similar routes in Santiago, we observed two key findings. Compared with the fixed‐wage system, the per‐passenger system leads to (1) 13% shorter passenger wait times, via reduced bunching of buses and (2) 67% more accidents per kilometer driven, via more aggressive driving. We discuss implications for the design of incentives in public transit. (JEL L92, M52, R41)     

Life pattern of urban trees: A growth-modelling approach

Urban afforestation improves life quality in urban centers providing social and environmental benefits. Understanding growth of urban trees exposed to air pollution will support planning, managing and expanding urban areas. This approach intends to determine growth patterns of urban trees to support future urban planning. Non-destructive samples were collected from trees of Araucaria angustifolia (Bertol.) Kuntze in Araucaria city, Parana State, Brazil. Growth rings were related to pollutant concentrations and meteorological series. Growth reduction was observed except in the border areas of the city. Trees established during or after the period of industrialization incentives were most affected by air pollution, indicating that immature plants are more vulnerable. Sulphur dioxide and nitric oxide significantly affected growth of smaller trees. Those greater than 60 cm dbh did not demonstrate significant correlation with any identified pollutant. As the trees established before accentuated urbanization were less affected by air pollution, it is reinforced the importance of preserving remaining urban trees. We suggest that planning urban afforestation should precede industries placing. When urban planning is impossible, new planted trees should not be expected to grow as in free pollution areas, but they will still present satisfactory diameter increment, contributing to improve local urban environment.

物质：马克思主义哲学的独特关注

文章认为哲学在探讨世界本源问题时所涉及的广阔研究范围与一定历史时期人们有限的知识水平和认知能力的矛盾一直是困扰哲学发展的一个十分重大的矛盾.马克思以往的哲学都因过多地关注于他们当时认识能力所达不到的虚无缥缈的宇宙从而难以摆脱半科学半假想的状况.马克思主义哲学立足于物质,关注于我们认识能力所能达到的这个有限的空间,从而有效地解决了这一困扰哲学发展的矛盾,使其哲学成为能够被实践所加以证明的科学.     

15-谜问题的可达性判定

定义了15-谜问题的6个动作规则,在此基础上证明了15-谜问题解的存在性判定的充分必要条件,其充分性的证明过程是一个构造性证明方法,提供了求解15-谜问题的一个解的可实现算法;同时,对此结论进行了扩展,对于给定的一初始格局和任一目标格局,证明了初始格局可达目标格局的的充分必要条件,其结论有助于构造问题的状态空间与限界函数。这两个结论从理论上完全解决了15-谜问题,对获得最优算法提供了理论基础。
