Environmental Education: Enhancing Learning and Awareness Through Assessment

Environmental issues are rapidly gaining momentum globally as humans try to find sustainable solutions to the effects of climate change, carbon emissions, and the actions of human-kind (see Olver, Blacklist those who ‘greenwash’. Companies must walk the talk regarding climate. The Times, 2011a; The weather warriors’ war. Real change will come when a few good men and women say ‘enough is enough’. The Times, 2011b). To enhance learning and awareness of environmental issues among Environmental Education students and the community at large, this study situated assessments within communities of practice around the university. Using action engagement within action research students had to work with insiders from the community to identify, formulate action or intervention plans and find solutions to problem situations in the community. Using action engagement within action research in this study definitely enhanced student’s knowledge of their community’s problems. Their personal involvement and the cyclical approach adopted, enhanced students’ emotional understanding and gave them an insider perspective into the situations and problems that required intervention; and trust was built between the students and members of the community as they worked together to accomplish a common goal.     

Enhancing Organisational Innovation Capability Through Systemic Action Research: A Case of a Swiss SME in the Food Industry

This paper presents detailed insights into the nature of innovation dynamics of an SME operating in the food industry. Furthermore, the paper highlights how Action Research has changed and enhanced SME??s capability to innovate. Within the exploratory action research based case study described in this article, the researchers interacted closely with one company with regards to a newly launched innovation process over a time period of more than 18 months. The analysis contributes to the fields of action research and innovation research in three respects: First, it exemplifies how systemic action research as a method can be applied on the organisational level in the private sector. Second, it demonstrates how useful action research can be for fostering the innovativeness and creativity of a company. Lastly, the analysis illustrates the extensive time horizon of an action research project.

垄断企业的顾客忠诚研究

尽管顾客忠诚对于企业具有重要的意义,在垄断行业内却对其缺乏足够的重视。以某居民供电企业为例,研究了垄断环境下顾客忠诚的维度结构,以及其同服务质量、顾客满意之间的关系。结果表明,垄断企业应了解并超出顾客的期望,通过提高服务质量和顾客满意水平,增强顾客对企业的信任度、合作度、宣传度和价格承受度,将虚假忠诚转化为真正的忠诚。     

Arresting the Collapse of the City Through Systemic Education: A Case Study of Melbourne

Though it is claimed that Melbourne is one of the most liveable cities in the world, a systemic examination, based not on mechanistic and utilitarian foundations but on a humanist, systemic science reveals that a variety of modalities of its social fabric are threatened and will drive the city to eventual collapse. As usual, the worst impacted are the most defenceless: the poor, the elderly and especially the young. We propose that an education that emphasises vision and ethics and that integrates the humanities with the natural sciences in a systemic approach should be the prime instrument of intervention. We describe a new Master of Arts degree designed on these principles to re-orientate young professionals towards the community and away from big business and commerce.

射频仿真系统的误差分析与可信度评估研究

首次将统计方法应用于射频仿真系统的可靠性分析中，总结出其应采用的一般方法。采用Grubbs准则对校准系统测得的实验数据中的粗大数据进行滤除，接着分别采用数据比较法和阿贝检验法对定值和变值两种系统误差是否显著进行检验，如果系统误差显著，则应采用实验比对的方法消除之，使随机性成为数据的主导因素。采用x^2-分析法确定数据概率分布，对合格区间进行概率密度的积分以确定可信度。这种方法易于通过编程实现，并由校准系统自动完成可信度评估。给出了它的算法描述与应用效果实例。

评价模式对评价可靠性的影响分析

所谓评价是指从被评对象主体中提取本质属性,使之转换成主观价值尺度,并用以度量被评对象的行为过程。 构成评价的基本要素有被评对象、评价目标、评价准则(指标集、模型集、结构)、评价群体和偏好、评价模式等。各基本要素的有机组合称为一个评价系统。对某一特定的评价问题,一旦相应的评价系统确定之后,则该评价问题就完全成为按既定步骤进行的“度量”问题。     

A GMRP Approach for Reliability Analysis of Repairable Systems

We propose here a mathematical approach for the study of repairable systems with arbitrary distributions. The idea is to define a new type of stochastic process, called a generalized Markov renewal process (GMRP). which may describe the transition behavior of the stochastic process at non-regenerative points. In the paper an analytical method for the GMRP is put forward and the formulas are then presented for reliability analysis of repairable systems which can be described by a GMRP with finite states. A signal flow graph technique for system modeling is also summarized here. Finally- an analytical model to evaluate the reliability of a m-out-of- n.G system with general repair-time distribution is developed by means of the GMRP approach.     

重复囚徒困境博弈中社会合作的仿真

利用Multi-Agent仿真方法建立了一个人工社会,研究了两种个体行为模式下社会合作的演化。在人工社会中有多个智能自适应主体,主体之间进行重复囚徒困境博弈,并采用模仿学习算法改进策略。在基本模型中没有个体的历史行为信息,系统自发演化;在信誉模型中,主体的历史行为累积为信誉,在交互前主体根据对方的信誉临时调整策略。仿真结果显示:系统的演化复杂多样,均有合作的突现和崩溃。对两模型的合作指标比较表明,根据信誉调整策略的行为模式对促进合作无显著效果。

A Comparison of Interactive Planning and Soft Systems Methodology: Enhancing the Complementarist Position

Flood and Jackson (1991) explain the diversity of systems-based methods with a pluralistic System of Systems Methodologies by categorizing the various methods according to the problem context for which they are deemed to be best suited. The two methods classified as most appropriate for complex-pluralistic problems, Ackoff's Interactive Planning and Checkland's Soft System Methodology, are compared according to their underlying theory, problem-solving techniques, and outcomes. Despite their shared focus on the same problem context, the two methods are derived from different ontological assumptions which yield different techniques and outcomes. An argument is presented for conducting additional comparisons of methods that address the same problem context.

Systemic Analysis of the Soccer (Football) Value Chain: Learning from the Brazilian Context

Soccer (football) is identified as the most popular sport in the world with a high turnover of economic-financial resources. The different segments of the soccer (football) value chain exert mutual influence on the variables that rule the dynamics of this sector. In this sense it is necessary to identify the variables that represent the soccer (football) value chain systemically; to understand the interrelationships between these variables, the main difficulties derived from this interrelationship and to point out variables that require actions to increment the results of the soccer (football) value chain as a whole. Hence, this study applied a semi-structured questionnaire with open-ended questions about the problems and leveraging variables that exist in this sports modality. A causal linkage diagram was elaborated based on the answers to the interviews, showing the systemic structure of the soccer (football) value chain in Brazil, whose premise it is to identify the existing circularities and the possibly existing points of leverage. The systemic structure pointed to the economic participation of soccer (football) in the Gross Domestic Product as a central variable to be leveraged, which tends to synthetize the results of the joint action of the actors in this chain. Furthermore, the variables that may limit or amplify the growth were identified. The systemic structure showed that the soccer (football) commodity chain is complex because of the great number of variables and interrelationships needed to represent its dynamics. The relationship between the actors also proved to be a factor of impact on economic and social development.
