    Uses of peer assessment in database teaching and learning

    This discussion paper introduces three very different methods and contexts for the use of peer assessment in introductory database classes, each of which is supported by different learning software tools. In the first case study, at Glasgow Caledonian University, Contributing Student Pedagogy is used, where students contribute to the learning of others through the collaborative creation of a bank of self-assessment questions. This is supported by the Peerwise software tool. Secondly, at the University of Strathclyde, students undertake formative assessment of others in providing feedback on an initial element of a larger coursework assessment. A number of virtual learning environments (VLEs) are capable of supporting this method through customisable discussion fora. Finally, at the Abertay University, peer and self assessment are used in a group project to adjust the group grade for individual students. This is effected through the use of the WebPA software tool

    Abstract—Online software forums provide a huge amount of valuable content. Developers and users often ask questions and receive answers from such forums. The availability of a vast amount of thread discussions in forums provides ample opportunities for knowledge acquisition and summarization. For a given search query, current search engines use traditional information retrieval approach to extract webpages containin

    Feature analysis for web forum question post detection

    A web forum which is also known as discussion board or Internet forum is an online community of users with a common interest. It is a problem-solving platform that engages experts across the globe. Both technical and non-technical problems are resolved on a daily basis within web forums. Research activities in this domain have been concentrated on answer detection with the assumption that the initial post of a thread is a question post. The quality of web forum question posts varies from excellent to mediocre or even spam. Detecting good question posts require utilization of salient features. In this paper, we implement a bag-of-words (BoW) model to mine web forum question posts. We empirically address the following questions in the paper. Can BoW model effectively detect web forum question post? What feature selection method is most appropriate for BoW model in this domain? Is choice of classifier influenced by web forum genre? We used three publicly available datasets of varying technical degrees for the experiments. The experimental results revealed that BoW can perform better than complex techniques that implement higher N-gram with part-of-speech tagging

    The Cure: Making a game of gene selection for breast cancer survival prediction

    Motivation: Molecular signatures for predicting breast cancer prognosis could greatly improve care through personalization of treatment. Computational analyses of genome-wide expression datasets have identified such signatures, but these signatures leave much to be desired in terms of accuracy, reproducibility and biological interpretability. Methods that take advantage of structured prior knowledge (e.g. protein interaction networks) show promise in helping to define better signatures but most knowledge remains unstructured. Crowdsourcing via scientific discovery games is an emerging methodology that has the potential to tap into human intelligence at scales and in modes previously unheard of. Here, we developed and evaluated a game called The Cure on the task of gene selection for breast cancer survival prediction. Our central hypothesis was that knowledge linking expression patterns of specific genes to breast cancer outcomes could be captured from game players. We envisioned capturing knowledge both from the players prior experience and from their ability to interpret text related to candidate genes presented to them in the context of the game. Results: Between its launch in Sept. 2012 and Sept. 2013, The Cure attracted more than 1,000 registered players who collectively played nearly 10,000 games. Gene sets assembled through aggregation of the collected data clearly demonstrated the accumulation of relevant expert knowledge. In terms of predictive accuracy, these gene sets provided comparable performance to gene sets generated using other methods including those used in commercial tests.

    The Determinants of the German Corporate Governance Rating

    Get PDF
    This paper analyzes the determinants of the German corporate governance rating recently developed by Drobetz, Schillhofer, and Zimmermann (2004). We find a non- linear relationship between ownership concentration and the quality of firmlevel corporate governance as measured by the rating. Firms with larger boards of directors have lower governance ratings, but firms that apply US-GAAP or IAS rules and/or use an option-based remuneration plan have higher corporate governance ratings. Our results question the comply-or-explain principle embedded in recent corporate governance codes and call for a more rules-based approach in improving corporate governance in Europe.Corporate governance, endogeneity, ownership structure, board size, accounting principles, executive compensation.
