  • A COST EFFECTIVENESS AND PROBABILISTIC SENSITIVITY ANALYSIS OF OPPORTUNISTIC SCREENING VERSUS SYSTEMATIC SCREENING FOR SIGHT THREATENING DIABETIC EYE DISEASE Theorem 2. Any equilibrium is perfectly stratified, in the sense that no family lives in a higher-quality, higher-price, or higher-peer-group district than does any higher income family. Corollary 2.1. In any equilibrium, the n families with incomes greater than ( ) N F −1 1− n live in the same community, which has higher quality (xδ +μ ) than any other.

  • Long distance word reordering is a major challenge in statistical machine translation research. Previous work has shown using source syntactic trees is an effective way to tackle this problem between two languages with substantial word order difference. In this work, we further extend this line of exploration and propose a novel but simple approach, which utilizes a ranking model based on word order precedence in the target language to reposition nodes in the syntactic parse tree of a source sentence....

  • In this paper, we propose a novel ranking framework – Co-Feedback Ranking (CoFRank), which allows two base rankers to supervise each other during the ranking process by providing their own ranking results as feedback to the other parties so as to boost the ranking performance. The mutual ranking refinement process continues until the two base rankers cannot learn from each other any more. The overall performance is improved by the enhancement of the base rankers through the mutual learning mechanism.

  • An efficient use of lexical cohesion is described for ranking text units according to their contribution in defining the meaning of a text (textual saliency), their ability to form a cohesive subtext (textual connectivity) and the extent and effectiveness to which they address the different topics which characterize the subject matter of the text (topic aptness).

  • This work describes an answer ranking engine for non-factoid questions built using a large online community-generated question-answer collection (Yahoo! Answers). We show how such collections may be used to effectively set up large supervised learning experiments. Furthermore we investigate a wide range of feature types, some exploiting NLP processors, and demonstrate that using them in combination leads to considerable improvements in accuracy.

  • Vietnam has been ranked as one of the most important country in the production of things in the world since 2000. To achieve high productivity, most growers rely heavily on pesticides and chemical fertilizers, leading to increased costs, health problems of farmers, pest resistance, environmental pollution and minimizing the natural enemies and pollinators. To make the production of safe, sustainable and profitable, integrated program improvement (ICI) is necessary.

  • Why is benchmarking SIEM important? According to the National Institute of Standards (NIST), SIEM software is a relatively new type of centralized logging software compared to syslog. Our SANS Log Management Survey1 shows 51 percent of respondents ranked collecting logs as their most critical challenge – and collecting logs is a basic feature a SIEM system can provide. Further, a recent NetworkWorld article2 explains how different SIEM products typically integrate well with selected logging tools, but not with all tools.

  • Unless the number of first year Ph.D. students is really big, the professors will know you by name or at least recognize you outside the classroom. It is to your advantage to have good relations with professors from the first year onwards, even tough you don’t do any (or much) research in your first year. Going to office hours and classroom discussions will contribute to this. It is also a good idea to attend the social events organized by your department, not only to have some time to relax, but also to chat with professors and other students and at...

  • While interaction operates on impressions, people are often naturally (or neurotically) motivated to suppress their own desires in order to please others (Rank 1932; Moustakas 1972). In other words, they seek to create a good impression. Social conformity, or collective action, relies on this behavior. The internal need to conform and the fear of perceived social gatekeepers creates a mechanism for society to be regulated by social norms.

  • A new problem in 2008, “Undocumented Workers (Illegal Aliens)” ranks 70th and is a critical issue for 11 percent of small business owners. Despite strong and diverse opinions on this issue and the extensive press coverage on it, undocumented workers are not a top-of- the-line issue for small business people in their business ownership capacity. The principle reason for concern is the problems that arise from unfair competition by those hiring illegal immigrants. Such competition apparently is not a pressing issue for many.
