Guiding data-driven design ideation by knowledge distance

Data-driven conceptual design methods and tools aim to inspire human ideation for new design concepts by providing external inspirational stimuli. In prior studies, the stimuli have been limited in terms of coverage, granularity, and retrieval guidance. Here, we present a knowledge-based expert system that provides design stimuli across the semantic, document and field levels simultaneously from all fields of engineering and technology and that follows creativity theories to guide the retrieval and use of stimuli according to the knowledge distance. The system is centered on the use of a network of all technology fields in the patent classification system, to store and organize the world’s cumulative data on the technological knowledge, concepts and solutions in the total patent database according to statistically-estimated knowledge distance between technology fields. In turn, knowledge distance guides the network-based exploration and retrieval of inspirational stimuli for inferences across near and far fields to generate new design ideas by analogy and combination. With two case studies, we showcase the effectiveness of using the system to explore and retrieve multilevel inspirational stimuli and generate new design ideas for both problem solving and open-ended innovation. These case studies also demonstrate the computer-aided ideation process, which is data-driven, computationally augmented, theoretically grounded, visually inspiring, and rapid.

生态系统服务权衡研究进展

生态系统服务作为连接自然与社会生态系统的桥梁，是社会-生态系统管理和分析的重要工具。生态系统服务权衡研究关注生态系统服务间关系的认知和调节，对于协调多元目标、最大化人类福祉、支撑社会-生态系统可持续利用具有重要的作用。整理了生态系统服务权衡的内涵和分类，将生态系统权衡研究分为客观权衡规律和管理权衡决策两大类，并对两类生态系统服务权衡的研究内容、思路和方法的国内外进展进行了系统梳理。在客观权衡规律方面，主要包括生态系统服务供与需间权衡规律、生态系统服务供或需间权衡规律两部分，其中，供与需间权衡规律包含供需匹配的维度和供需匹配的研究方法两部分，供或需间权衡规律包含关系识别和驱动力分析两部分；在管理权衡决策方面，主要包括生态系统服务管理权衡决策的准则确定和求解思路两部分。最后，对生态系统服务权衡研究进行了国内外进展的总体评价和研究展望。目前，客观权衡规律研究较为成熟，继生态系统服务供给侧权衡研究的热点之后、需求侧的权衡研究也逐渐增多，但整体上仍存在研究的应用指向不明、研究结果稳健性不足的问题；管理权衡决策研究易忽视决策准则的设置问题，使得决策结果的可行性存疑。因此，应当提出生态系统服务权衡研究范式，整合客观权衡规律和管理权衡决策，提升客观权衡规律研究的应用指向。在客观规律探索方面，深化对权衡规律驱动机制的研究，开展多时空尺度耦合研究，明确权衡规律的稳健性。在权衡决策管理方面，重视决策标准的设置，加强多方参与决策，深入探讨生态系统服务和人类福祉的联系，使权衡准则更加贴近区域管理的真正需求，提升决策结果的可行性。在实证研究方面，权衡决策研究对我国自然保护地的关注不足，未来应在继续推进城镇地区研究的基础上，尝试填补保护地的研究空缺，服务于我国保护地紧迫的权衡管理需求。;Ecosystem services, as a bridge connecting natural and social ecosystems, are important tools for social-ecological system management and analysis. Ecosystem services tradeoff researches focus on the cognition and regulation of the relationship between ecosystem services, which plays an important role in coordinating multiple goals, maximizing human well-being, and supporting the sustainable use of social-ecological system. This paper summarizes the connotation and classification of ecosystem service tradeoff, divides ecosystem service tradeoff research into two categories:objective tradeoff law and management tradeoff decision, and systematically reviews the domestic and international progress of the research content, ideas and methods of ecosystem service tradeoff. In terms of objective tradeoff law, it mainly includes tradeoff relationship between ecosystem service supply and demand, and tradeoff relationship between ecosystem service supply or demand. Tradeoff relationship between ecosystem service supply and demand includes matching dimensions and matching research methods. Tradeoff relationship between ecosystem service supply or demand includes relationship recognition and driving force analysis. In the aspect of management tradeoff decision, it mainly includes the criterion determination and the problem-solving ideas. In the end, the overall evaluation and research prospect of the progress at home and abroad were made. At present, the research on objective tradeoff law is relatively mature, and following the supply side, the tradeoff research on the demand side of ecosystem service also gradually increased, but there remains some problems such as unclear application direction and insufficient robustness of research results. In the researches of management tradeoff decision, it is easy to ignore the setting of decision criterion, which makes the feasibility of the result doubtful. We suggested that the research paradigm of ecosystem service tradeoff needed to integrate the objective tradeoff law and management tradeoff decision, to make the objective tradeoff law researches more application oriented. In terms of the exploration of objective laws, we should deepen the research on the driving mechanism that forms the law of tradeoffs, carry out the research on the coupling of multiple space-time scales, and clarify the robustness of the law of tradeoffs. In the aspect of tradeoff decision management, it should attach importance to the setting of decision-making criteria, strengthen the participation of multiple parties in decision-making, and deeply explore the relationship between ecosystem services and human well-being, so as to make the tradeoff criteria more close to the real needs of regional management and improve the feasibility of decision-making results. In the aspect of empirical research, the research of trade-offs decision paid insufficient attention to Chinese protected areas. In the future, we should try to fill the research gap of the protected areas while continuing to promote the study of urban areas, to serve the urgent tradeoff management needs of the protected areas in China.

Impacts of Metacognition on Innovative Behaviors: Focus on the Mediating Effects of Entrepreneurship

Metacognition is important as a leading factor in enhancing innovation behavior because it involves elements of planning, monitoring, and regulating for specific actions in the creation and introduction of new ideas. A more extended approach is needed in the interpretation and application of entrepreneurship. Considering entrepreneurship as the exclusive property of top management within the enterprise is not beneficial as it limits the scope for entrepreneurship, given the importance of entrepreneurship and the economic and social significance of corporate success. Entrepreneurship education provides trainees with a way to work within the global dimension of their economic activities and their influence, and to understand the various elements of the economy and society they live in and the process of their transformation. In order to explore existing knowledge and new knowledge, it is necessary to take more innovative actions by responding flexibly to unforeseen situations and utilizing the knowledge required for various tasks. The lack of intrinsic motivation to demonstrate innovative behavior can lead to individual differences in innovation behavior. Those who are given intrinsic motivation are learning-oriented and say that they want to get rid of stereotypes and get new alternatives and ideas for problem solving.

Management mechanisms for development of personnel professional competencies at a loading and haulage company

The necessity for development a management mechanism for development of personnel professional competencies at a loading and haulage company in order to ensuring the compliance of competencies with labor functions, regulated by the current professional standards, is substantiated. A functional diagram of the organizational and technical system of the loading and haulage company was developed, that includes the interaction mechanism between the personnel and the objects of the main production. The problem of algorithm development to assess the correspondence of communicative competencies and labor functions of loading and haulage companies, ensuring the achievement of the management goal with a minimum risk of an emergency situation or an accident, was set and solved. The idea of management problem solving consists in the operational development and implementation of anticipatory measures at each deviation in personnel actions from normative or target indicators. The dependence of the risk of imbalance of communicative competences and labor functions in a given period of time is established. The effectiveness of the developed and implemented mechanism is confirmed by the positive dynamics of the test results.

Assessment of modularity architecture for recovery process of electric vehicle in supporting sustainable design

The electric vehicle is one of the innovations to reduce the pollution of the vehicle. Nevertheless, it still has a problem, especially for disposal stage. In supporting product design and development strategy, which is the idea of sustainable design or problem solving of disposal stage, assessment of modularity architecture from electric vehicle in recovery process needs to be done. This research used Design Structure Matrix (DSM) approach to deciding interaction of components and assessment of modularity architecture using the calculation of value from 3 variables, namely Module Independence (MI), Module Similarity (MS), and Modularity for End of Life Stage (MEOL). The result of this research shows that existing design of electric vehicles has the architectural design which has a high value of modularity for recovery process on disposal stage. Accordingly, so it can be reused and recycled in component level or module without disassembly process to support the product that is environmentally friendly (sustainable design) and able reduce disassembly cost.

An Analysis of Looking Back Method in Problem-Based Learning: Case Study on Congruence and Similarity in Junior High School

This study aims to understand how learners do look back their idea of problem solving. This research is based on qualitative approach with case study design. Participants in this study were xx students of Junior High School, who were studying the material of congruence and similarity. The supporting instruments in this research are test and interview sheet. The data obtained were analyzed by coding and constant-comparison. The analysis find that there are three ways in which the students review the idea of problem solving, which is 1) carried out by comparing answers to the completion measures exemplified by learning resources; 2) carried out by examining the logical relationship between the solution and the problem; and 3) carried out by means of confirmation to the prior knowledge they have. This happens because most students learn in a mechanistic way. This study concludes that students validate the idea of problem solving obtained, influenced by teacher explanations, learning resources, and prior knowledge. Therefore, teacher explanations and learning resources contribute to the success or failure of students in solving problems.

Piloting the multi-family approach in community-based rehabilitation: an observational and interview-based study

BackgroundIn Palestine, as in many societies, children with a physical or mental disability and their families often experience stress related to stigma and isolation. Over the course of one year, the community-based rehabilitation programme in the north of the West Bank pioneered a multi-family group approach, originally developed in the UK, to facilitate six support groups for a total of approximately 50 mothers of children with a disability. The method is based on the premise that people who share similar situations can provide company, stress relief, and practical problem-solving ideas to each other. MethodsWe conducted intervention research into the implementation and adaptation of the multi-family group approach to the local context. This research included systematic participatory observation of group sessions, reflection meetings, and training workshops, and informal interviews with 12 community-based rehabilitation workers and supervisors throughout the process of design of the project, initial specialist training of community health workers, and on-the-job mentoring. We conducted systematic comparative analysis of all observation notes and informal interviews. We obtained ethics approval and informed consent. FindingsCommunity-based rehabilitation teams gradually gained confidence in co-facilitating groups using the multi-family group approach techniques. The sessions combined enjoyment and relaxation with serious discussions over shared personal, family, and community experiences, and provided the participants with new ways for seeking and offering support. Over time, observations in sessions and interviews with mothers and group facilitators suggested that social isolation among group members diminished and mothers became more active in the group and the wider community. InterpretationThe multi-family group approach has meant that the group participants are no longer merely programme beneficiaries but have become active participants in the psychosocial component of community-based rehabilitation. Although in the West this approach is mostly implemented by specialists, our study shows that with intensive training and on-the-job mentoring, community health workers can successfully adapt the method to develop social support networks for mothers of children with a disability in Palestinian and possibly other non-Western settings.

Building Actor Relationships and Alliances for Complex Problem Solving in Spatial Planning: The Test Planning Method

In order to explore, clarify and solve complex challenges in spatial development, effective cooperation between spatially significant actors is essential. To this end, formal methods and instruments have been in place since the early 1970s. These are based on legal principles and existing established organizations. However, in recent decades it has become clear that this formal repertoire is, in most cases, insufficient. The sheer complexity of the associated challenges presents formal methods – and the actors involved – with a serious challenge. A key weak point is most notably the series of connected procedures necessary when trying to find a solution and the inertia of hierarchically structured organizations when faced with collaboration. These methods are referred to in the industry as “consecutive methods”.As a way of supplementing formal processes, recent decades have seen the appearance of informal procedures as a result. These are typically characterized by direct dialogue between competing problem-solving ideas, along with constructive criticism, within the context of processes that are structured according to a definite timeframe and based on particular principles. Such processes are typically referred to as “simultaneous methods”. These allow for versatile operational implementation when the appropriate method is used.In German-speaking countries, and in Switzerland in particular, one such method has taken root: the test planning method. The following article focuses on this method, its principles and its underlying philosophy, all of which are illustrated by means of case studies. The article concludes with an outlook in terms of future prospects.

Engaging Frontline Leaders and Staff in Real-Time Improvement

The relationship of staff satisfaction and engagement to organizational success, along with the integral influence of frontline managers on this dimension, is well established in health care and other industries. To specifically address staff engagement, Virginia Mason Medical Center, an integrated, single-hospital health system, developed an approach that involved leaders, through the daily use of standard work for leaders, as well as staff, through a Lean-inspired staff idea system. Kaizen Promotion Office (KPO) staff members established three guiding principles: (1) Staff engagement begins with leader engagement; (2) Integrate daily improve- ment (kaizen) as a habitual way of life not as an add-on; and (3) Create an environment in which staff feel psycho- logically safe and valued. Two design elements--Standard Work for Leaders (SWL) and Everyday Lean Ideas (ELIs) were implemented. For the emergency department (ED), an early adopter of the staff engagement work, the challenge was to apply the guiding principles to improve staff engagement while improving quality and patient and staff satisfaction, even as patient volumes were increasing. Daily huddles for the KPO staff members and weekly leader rounds are used to elicit staff ideas and foster ELIs in real time. Overall progress to date has been tracked in terms of staff satisfaction surveys, voluntary staff turnover, adoption of SWL, and testing and implementation of staff ideas. For example, voluntary turnover of ED staff decreased from 14.6% in 2011 to 7.5% in 2012, and 2.0% in 2013. Organizationwide, at least 800 staff ideas are in motion at any given time, with finished ones posted in an idea supermarket website. A leadership and staff engagement approach that focuses on SWL and on capturing staff ideas for daily problem solving and improvement can contribute to organization success and improve the quality of health care delivery.

An Investigation of Secondary Teachers’ Understanding and Belief on Mathematical Problem Solving

Weaknesses on problem solving of Indonesian students as reported by recent international surveys give rise to questions on how Indonesian teachers bring out idea of problem solving in mathematics lesson. An explorative study was undertaken to investigate how secondary teachers who teach mathematics at junior high school level understand and show belief toward mathematical problem solving. Participants were teachers from four cities in East Java province comprising 45 state teachers and 25 private teachers. Data was obtained through questionnaires and written test. The results of this study point out that the teachers understand pedagogical problem solving knowledge well as indicated by high score of observed teachers‘ responses showing understanding on problem solving as instruction as well as implementation of problem solving in teaching practice. However, they less understand on problem solving content knowledge such as problem solving strategies and meaning of problem itself. Regarding teacher's difficulties, teachers admitted to most frequently fail in (1) determining a precise mathematical model or strategies when carrying out problem solving steps which is supported by data of test result that revealed transformation error as the most frequently observed errors in teachers’ work and (2) choosing suitable real situation when designing context-based problem solving task. Meanwhile, analysis of teacher's beliefs on problem solving shows that teachers tend to view both mathematics and how students should learn mathematics as body static perspective, while they tend to believe to apply idea of problem solving as dynamic approach when teaching mathematics.

ANALISIS KEMAMPUAN KOMUNIKASI MATEMATIS DALAM PEMECAHAN MASALAH MATEMATIKA SESUAI DENGAN GAYA KOGNITIF DAN GENDER

SMPN 1 Batanghariin the second semester of the academic year 2012/2013. They were two students who had field dependence cognitive style and two students who had field independence cognitive style. The subjects were taken by using the purposive sampling technique. The data of this research were gathered through think aloud method. The data were then analyzed by using the technique with the procedureas follows: (1) the data were classified on the basis of the indicators of mathematical communication after the data had been obtained from the first and the second collections; (2) the data were presented in table form; and (3) the conclusions were drawn. The validity of the data was conducted by using time triangulation. The result of this research were analyzed by using constant comparison in which subject in i ( i = 1, 2) with the j ( j = 1, 2) cognitive style which was already valid as well compared with subject in k ( k = 1, 2) with the the j ( j = 1, 2) cognitive style which was already valid as well. The equal ability of mathematical communication was made the main finding wheares the different ability of mathematical communication was made the other finding. The result of this research valid because of the dependability proved. The ability of mathematical communication of the students with the field dependence cognitive style is different from that of those with the field independence cognitive style. The students with the field dependence cognitive style can communicate the ideas in written way well but they have difficulties in communicating ideas in spoken way as well as inclination to receive information without reorganizing it in such a way that the problem-solving ideas presented cannot reveal the actual problem solution. Meanwhile, the students with the field independence cognitive style can communicate the ideas well in both spoken and written ways and process as well as reorganize information in such a way that the problem-solving ideas presented can reveal the actual problem solution.
