The use of information by environmental planners: A qualitative study using Grounded Theory methodology

The purpose of this study was to examine the use of information by environmental planners. The study used the Grounded Theory method to develop a theoretical model that explains the reasons for using information and the factors that motivate such use. Forty-four semi-structured interviews were conducted in workplace environments to collect data on the way the respondents used information in projects that they had done before. Data were analysed in accordance with the Grounded Theory techniques of constant comparison. The study found that the planner’s perceptions of: their own competences, resistance of the stakeholders, role requirement; and the impressions on the enabling effect of the information environment drive the self-empowerment behaviour of the planners. This behaviour is characterised by actions involving information acquisition, packaging as well as giving information to stakeholders during the facilitation of the environmental planning process. The experiential knowledge levels of individuals enhance the self-empowerment behaviour exhibited by environmental planners. Based on the informational power derived from the self-empowerment activities, the planners select a strategy for participation that they deem appropriate for an environmental planning project, consequently facilitating the process to develop widely accepted environmental plans.

Fostering integration of informational texts and virtual labs during inquiry-based learning

Inquiry-based learning allows students to learn about scientific phenomena in an exploratory way. Inquiry-based learning can take place in online environments in which students read informational texts and experiment in virtual labs. We conducted two studies using eye-tracking to examine the integration of these two sources of information for students from vocational education (78 and 71 participants, respectively, mean age of 13 years and 7 months). In Study 1, we examined whether the amount of time spent on reading text and on integrating the text content with information from a virtual lab (as measured via gaze switches between the text and the lab) affected the quality of the inquiry-based learning process in the lab (i.e., correctly designed experiments and testable hypotheses created) and the learning gain (increase in domain knowledge from pretest to posttest). Results showed, on average, a gain in domain knowledge. Pretest scores were related to posttest scores, and this relation was mediated by the score for correctly designed experiments in the lab. There was no relation between informational text reading time and inquiry process quality or learning gain, but more frequent integration was associated with a higher score for experimentation in the virtual lab, and more frequent integration attenuated the relation between pretest score and designing correct experiments. Integration could thus compensate for the negative effects of lower prior knowledge. In Study 2, we examined whether integration was stimulated by highlighting correspondences between the informational text and the virtual lab (i.e., signaling). Integration was higher than in Study 1, but this did not further improve the quality of the inquiry process or the learning gain. A general conclusion is that integration fosters inquiry-based learning, but that stimulating additional integration may not result in further improvement.     

基于GIS技术的陆上风能资源开发制约因素分析

本文采用中国气象局的风能资源数值模式系统,模拟了甘肃酒泉风电规划区较高分辨率（1km×1km）的50m高度平均风能资源分布状况。结果表明,玉门市昌马乡西部、瓜州县柳园镇附近、敦煌西部与新疆哈密交界区以及马鬃山镇附近年平均风功率密度和年有效小时数均较大,属于风资源较丰富区,有利于大规模风电开发。通过与测风塔实测数据的对比检验,评估了数值模拟结果的准确度。根据实际地形地貌和土地利用等基础地理信息,采用ArcGIS空间分析技术和建模工具分析了影响甘肃酒泉风电基地风能资源开发的主要制约因素,扣除不可开发区和限制开

采用文献资料和逻辑分析等方法,运用经济学、管理学、社会学和体育学等相关理论,对我国高校体育产业化的制约因素和发展对策进行研究。我国高校体育产业虽说拥有稳定的消费群体、充分的闲暇时间、优越的人力资源和丰富的物质设施等优势,但产业化过程中存在思想观念滞后、政策法规的支持力度不够、产权关系不明晰且经营范围偏小、经营方式单一且经营资金不足、缺乏经营人才而管理水平偏低等制约因素;进一步解放思想和转变观念、利用自身的资源优势开拓市场、完善政策法规和推进社会化改革、加强对体育产业应用型人才的培养等方面提出相应的发展对策。     

Exploring the factors,affordances and constraints outlining the implementation of Artificial Intelligence in public sector organizations

Artificial Intelligence (AI) is viewed as having great potential for the public sector to improve the management of internal activities and the delivery of public services. However, realizing its potential depends on the proper implementation of the technology, which is characterized by unique factors, that afford or constrain its use. What these factors are and how they affect AI implementation is still poorly understood, and scholars call for studies to add empirical evidence to the existing knowledge. This study relies on a case study methodology and, by adopting an abductive approach, applies a double theoretical perspective: the Technology-Organization-Environment (TOE) framework and the Technology Affordances and Constraints Theory (TACT). Drawing on these combined lenses, we develop a conceptual framework that extends previous studies by showing how AI implementation is the result of a combination of contextual factors that are deeply interrelated and, specifically, how AI-related factors bring new affordances and constraints to the application domain.
