Assessment for Learning of Design Teamwork Skills

This article seeks to contribute to the reflection around the training of future designers regarding teamwork. Collaboration, teamwork and negotiations are common everyday interactions that are now known to contribute positively to the design process. This article builds on a theoretical model that was initially proposed as a Ph.D. thesis contribution: the zone of proximal development for learning teamwork skills. The objective of this article is to share the first implementation of the model in a real educational situation and seize this opportunity to develop it further. The framework of assessment for learning and the concept of the zone of proximal development guide this research. The data collection is based on the observations of teamwork during a design seminar. The analysis is structured around the theoretical definitions of the model's components and in situ observations of the participants. This process guides us to share indicators allowing to confirm if a level or set of skills are achieved by a student. Plus, we propose a set of related teaching guidance to use when skills are identified as underdeveloped or to develop. Through this work, we wish to discuss how design students can be better equipped to enter the profession and play a significant role as team players.

Natural surface design for sliding mode control with multiple discontinuous inputs

It is well known that sliding mode control is based on the definition of an invariant manifold, where the system dynamics are forced to in a finite time. Such a manifold is somewhat arbitrarily defined, as long as the system dynamics are stable on it. Computational and control effort may vary depending on selected manifold. Obviously, if a system has naturally acceptable stable dynamics around a desired equilibrium point, no control is needed unless uncertainties or disturbances are present. It would be desirable that if such a system had uncertainties or disturbances, the control effort be designed only to overcome the effect of such factors. For a system with first order dynamics and affine control input, designing a sliding mode control overcoming only such uncertainties or disturbances is a trivial task. When a higher order dynamics system is involved, unit control may be used, where the input control signals are not discontinuous, but when only discontinuous control inputs are available, a design approach is not readily available. In this paper, taking advantage of the natural stable dynamics of a system, a sliding mode control approach is introduced for designing multiple discontinuous control inputs, where the control effort overcomes only uncertainties, disturbances or unstable dynamics. Two illustrative examples are given in order to show the feasibility of the method.     

A Strategy for Operationalizing Privacy by Design

Recent controversies surrounding privacy have sparked a move by regulators toward the idea of privacy by design (PbD), a concept pioneered by Ontario Information and Privacy Commissioner Ann Cavoukian. Industry has also started to recognize the importance of taking privacy seriously, with various PbD corporate initiatives currently underway. However, some commentators have criticized PbD for being too vague. Using three case studies and a range of best practice examples of PbD, privacy impact assessments (PIAs), and privacy-enhancing technologies (PETs), this article addresses the gap between the abstract principles of PbD and their operationalization into more concrete implementation guidelines for software engineers.     

Expert group formation using facility location analysis

In this paper, we propose an optimization framework to retrieve an optimal group of experts to perform a multi-aspect task. While a diverse set of skills are needed to perform a multi-aspect task, the group of assigned experts should be able to collectively cover all these required skills. We consider three types of multi-aspect expert group formation problems and propose a unified framework to solve these problems accurately and efficiently. The first problem is concerned with finding the top k experts for a given task, while the required skills of the task are implicitly described. In the second problem, the required skills of the tasks are explicitly described using some keywords but each expert has a limited capacity to perform these tasks and therefore should be assigned to a limited number of them. Finally, the third problem is the combination of the first and the second problems. Our proposed optimization framework is based on the Facility Location Analysis which is a well known branch of the Operation Research. In our experiments, we compare the accuracy and efficiency of the proposed framework with the state-of-the-art approaches for the group formation problems. The experiment results show the effectiveness of our proposed methods in comparison with state-of-the-art approaches.     

考虑视觉感官舒适度的园林建筑层次设计

利用传统算法在进行园林建筑设计的过程中,由于园林建筑层次受到设计人员主观因素的影响较大,难以进行准确的层次提取,造成设计效率和园林建筑层次感降低。为此,提出考虑视觉感官舒适度的园林建筑层次设计方法。根据韦伯-费普勒相关原理,建立园林中不同建筑物数目与视觉感官舒适度模型。针对模型中不同建筑物的主要特征进行提取,获取不同建筑物主要特征之间的映射关联性,从而完成视觉感官舒适度的园林建筑层次设计。实验结果表明,利用本文算法进行园林建筑层次设计,能够显著降低设计时间,提高园林建筑的层次感,效果令人满意。

中国再生资源产业知识产权运用机制顶层设计

2008年,《国家知识产权战略纲要》首次将知识产权运用的能力提升作为知识产权工作的重点。站在产业层面研究如何通过提升产业知识产权运用能力促进再生资源产业持续健康发展。根据废弃物再利用中所涉及知识产权性质的不同,将再生资源产业分为再制造产业和再生产产业。从再生资源产业链出发,梳理知识产权运用关联主体,包括原产品制造商、再利用商、消费者和政府,各主体间存在利益冲突,难以形成科学合理的知识产权运用机制。以机制设计理论为指导,以顶层设计理论为方法,自上而下系统设计再生资源产业知识产权运用机制,包括促进机制、支持机制、共享机制和拉动机制,勾画再生资源产业知识产权运用机制蓝图并提出发展意见和建议。
