Promoting case indexing in case library learning: Effects of indexing prompts on self-explanation and problem solving

In case library learning, an instructional method that promotes case-based problem solving, learners often struggle with indexing cases. Poor case indexing may hamper retention and retrieval of cases, hindering the construction of mental libraries in learners. To address this issue, the authors developed two indexing prompt types, explanation-based and difference-based, and explored their effects on self-explanation and problem solving in case libraries. A total of 105 students across three sections of a career development course participated in the study. Each section was assigned to one of three conditions: explanation-based indexing, difference-based indexing and no indexing prompt. Both indexing prompts facilitated self-explanation, which elaborated corresponding aspects of cases on which the prompts mainly focused. In arguing for a solution, learners relied more heavily on domain knowledge regardless of prompt types. However, both indexing prompt groups outperformed the control group in rebuttals. The authors discussed the theoretical and practical implications of the study.     

径欲曲、桥欲危、亭欲朴——谈园林中的径、桥、亭

《建筑学报》1981年12期刊载赵一鹤同志《略谈园林中的路、桥、亭》一文，对园林中路、桥、亭意境设计的论述，读后很有感触。但文中将《清闲供》中的“径欲曲、桥欲危、亭欲朴”，误引为“路欲曲、桥欲断、亭欲危”，通过论析，证明中国传统艺术特点之一是含蓄，山水园林艺术强调意境，注重诗情画意，追求“永恒的美和自然”。“径欲曲，桥欲危，亭欲朴”的思想，正是“山水诗”中的和谐旋律。     

Argument-based mixed recommenders and their application to movie suggestion

Recommender systems have become prevalent in recent years as they help users to access relevant items from the vast universe of possibilities available these days. Most existing research in this area is based purely on quantitative aspects such as indices of popularity or measures of similarity between items or users. This work introduces a novel perspective on movie recommendation that combines a basic quantitative method with a qualitative approach, resulting in a family of mixed character recommender systems. The proposed framework incorporates the use of arguments in favor or against recommendations to determine if a suggestion should be presented or not to a user. In order to accomplish this, Defeasible Logic Programming (DeLP) is adopted as the underlying formalism to model facts and rules about the recommendation domain and to compute the argumentation process. This approach has a number features that could be proven useful in recommendation settings. In particular, recommendations can account for several different aspects (e.g., the cast, the genre or the rating of a movie), considering them all together through a dialectical analysis. Moreover, the approach can stem for both content-based or collaborative filtering techniques, or mix them in any arbitrary way. Most importantly, explanations supporting each recommendation can be provided in a way that can be easily understood by the user, by means of the computed arguments. In this work the proposed approach is evaluated obtaining very positive results. This suggests a great opportunity to exploit the benefits of transparent explanations and justifications in recommendations, sometimes unrealized by quantitative methods.

Automatic generation of matter-of-opinion video documentaries

In this paper we describe a model for automatically generating video documentaries. This allows viewers to specify the subject and the point of view of the documentary to be generated. The domain is matter-of-opinion documentaries based on interviews. The model combines rhetorical presentation patterns used by documentary makers with a data-driven approach. Rhetorical presentation patterns provide the viewer with an engaging viewing experience, while a data-driven approach can be applied to growing media repositories. To date, the modeling of rhetoric has been achieved in a top-down manner using closed repositories, while data-driven generation approaches were unable to implement non-trivial rhetorical presentation patterns. We describe an implementation of our model in a system, Vox Populi, and apply it to an online documentary shot by a group of independent amateur documentarists.

非岩溶山区建设项目水资源论证技术浅析

人类利用开发程度较低的非岩溶山区一般以近河取水为主要供水方式,取水建筑物多位于河岸或河底,从供水形式上看属于取用地下水,但取水量的大小依赖于河流流量,因此实质上和地表水关系更加密切。根据非岩溶山区取用水的特点,对其建设项目水资源论证的技术问题进行了深入分析,重点对论证范围、地表水资源量和地下取水水源的保证程度等问题进行了研究并给出了相应的解决办法,以对今后类似地区进行建设项目水资源论证具有一定的指导意义。
