寒地大学校园环境要素与冬季体力活动相关性

为探究促进冬季体力活动的寒地大学校园环境设计依据,基于循证设计理论和社会生态学模型在中国东北地区9座大学校园年内进行了问卷调查,用实证方法探究了寒地大学校园的建成、气候及感知环境要素对学生冬季体力活动频率和水平的影响.通过描述性统计横向对比了学生冬季与非冬季月份的体力活动模式及各个校园的主观评价得分;并通过多重线性回归分析探求了校园环境要素对冬季体力活动的影响.统计结果表明:学生在冬季月份进行体力活动的频率和总量低于非冬季月份;校园冬季环境质量低于非冬季月份,且设施防寒、步行可达性、交通安全性、冬季活动安全性得分较低;在冬季,目的地多样性、公共交通选择多样性、道路交通网络连通性、步行道路环境品质、辅助设施存在性、犯罪安全性与交通性体力活动正相关,冰雪危害和空气污染与交通性体力活动负相关;校园环境与冬季休闲性活动无相关关系.利用上述数据可以初步推测促进体力活动的寒地大学校园环境设计倾向并对各个环境要素的重要程度进行评级,重要程度较高的要素是校内目的地、步行道路、犯罪安全性、步行辅助设施和校园公共交通服务.

Validation of “alarm bar” alternative interface for digital control panel design: A preliminary experimental study

Properly designed alarm systems can benefit operators in conducting routine and emergency tasks. With the digitization of main control rooms, the alarm interface can be designed in various ways that are different from the traditional “alarm tile” style. An innovative alarm bar interface is proposed in this paper. A preliminary lab experiment was conducted to compare the traditional alarm tile and the new alarm bar interfaces. Sixteen university students were recruited to participate in the experiment, in which two emergency scenarios, Loss of Coolant Accident and Steam Generator Tube Rupture, were tested. The experiment task included two parts: alarm detection and identification. The subjective ratings supported the innovative alarm bar design for better parameter trend perception. The objective performance measures showed that the simpler design of the alarm tile interface better aided the alarm detection performance, whereas the alarm bar interface had almost the same alarm identification performance as the alarm tile interface.Relevance to industryAn alarm system is critical for a complex industrial system. The experimental results show that design evaluation is more complex than it may seem. Although it has not been proved to be overwhelmingly superior to the tile design, the alarm bar design shows promise for aiding operators and needs to be further validated.     

Perception of city management,fellow residents,and Perceived External Prestige (PEP) as antecedents of city affective commitment - The city marketing perspective

This study analyses the role of perception of city management, perception of fellow residents, and Perceived External Prestige (PEP) on affective commitment from the city marketing perspective. The research model is tested based on the data collected on the residents of two different cities, on residents (N = 402) of Ljubljana – Green capital of Europe, 2016, and (N = 403) of Maribor – Capital of Culture, 2012. The results showed that both Perceived External Prestige and perception of fellow residents were significant drivers of city commitment. Perception of city management had a significant effect on Perceived External Prestige and perception of fellow residents, although no significant direct effect on city commitment. The results revealed that Perceived External Prestige and perception of fellow residents mediate the relationship between perception of city management and affective commitment fully. The study recognises the relationships between analysed variables, and confirms their crucial role as drivers of the residents' city commitment.

A cross‐cultural comparison of colour emotion for two‐colour combinations

Psychophysical experiments were conducted in the UK, Taiwan, France, Germany, Spain, Sweden, Argentina, and Iran to assess colour emotion for two‐colour combinations using semantic scales warm/cool, heavy/light, active/passive, and like/dislike. A total of 223 observers participated, each presented with 190 colour pairs as the stimuli, shown individually on a cathode ray tube display. The results show consistent responses across cultures only for warm/cool, heavy/light, and active/passive. The like/dislike scale, however, showed some differences between the observer groups, in particular between the Argentinian responses and those obtained from the other observers. Factor analysis reveals that the Argentinian observers preferred passive colour pairs to active ones more than the other observers. In addition to the cultural difference in like/dislike, the experimental results show some effects of gender, professional background (design vs. nondesign), and age. Female observers were found to prefer colour pairs with high‐lightness or low‐chroma values more than their male counterparts. Observers with a design background liked low‐chroma colour pairs or those containing colours of similar hue more than nondesign observers. Older observers liked colour pairs with high‐lightness or high‐chroma values more than young observers did. Based on the findings, a two‐level theory of colour emotion is proposed, in which warm/cool, heavy/light, and active/passive are identified as the reactive‐level responses and like/dislike the reflective‐level response. © 2010 Wiley Periodicals, Inc.

The 2012 free and open source GIS software map – A guide to facilitate research,development, and adoption

Over the last decade an increasing number of free and open source software projects have been founded that concentrate on developing several types of software for geographic data collection, storage, analysis and visualization. We first identify the drivers of such software projects and identify different types of geographic information software, e.g. desktop GIS, remote sensing software, server GIS etc. We then list the major projects for each software category. Afterwards we discuss the points that should be considered if free and open source software is to be selected for use in business and research, such as software functionality, license types and their restrictions, developer and user community characteristics, etc. Finally possible future developments are addressed.
