  • Performance evaluation measures the skill of an asset manager and its principal idea is to compare the returns with an alternative appropriate portfolio to that which was obtained in a particular case. The emergence of modern portfolio theory (MPT) by Markowitz (1952), who quantifies how rational investors make decisions based on expected return and risk, has brought much development to portfolio performance measurement.

  • Risk has become one of the main topics in fields as diverse as engineering, medicine, and economics, and it is also studied by social scientists, psychologists, and legal scholars. But the topic of risk also leads to more fundamental questions such as:What is risk?What can decision theory contribute to the analysis of risk? What does the human perception of risk mean for society? How should we judge whether a risk is morally acceptable or not? Over the last couple of decades, questions like these have attracted interest from philosophers and other scholars into risk theory.

  • Given a collection of records (training set ) Each record contains a set of attributes, one of the attributes is the class. Find a model for class attribute as a function of the values of other attributes. Goal: previously unseen records should be assigned a class as accurately as possible. A test set is used to determine the accuracy of the model. Usually, the given data set is divided into training and test sets, with training set used to build the model and test set used to validate it.

  • I am encouraged in arguing for such a view by a trend that seems to characterize some recent anthropological and philosophical literature, a trend towards recognizing that aesthetics may be usefully defined independently of art. The anthropologist Jacques Maquet, for example, has argued repeatedly (e.g. 1979: 45; 1986: 33) that art and aesthetics are best treated as independent. Among philosophers, Nick Zangwill (1986: 261) has argued that ‘one could do aesthetics without mentioning works of art! Sometimes I think it would be safer to do so.’ And T. J. ...

  • This paper describes novel and practical Japanese parsers that uses decision trees. First, we construct a single decision tree to estimate modification probabilities; how one phrase tends to modify another. Next, we introduce a boosting algorithm in which several decision trees are constructed and then combined for probability estimation. The two constructed parsers are evaluated by using the EDR Japanese annotated corpus. The single-tree method outperforms the conventional .Japanese stochastic methods by 4%. ...

  • Making decisions under conditions of risk and uncertainty is one of the most important activities that managers engage in. Generally, there is a lack of information and a limited amount of time available to make the decision. Procrastinating and not making a decision sometimes has greater risk than making it.

  • The solid product is a wet sludge of calcium sulfate which can be disposed of easily. So FGD does not eliminate pollution. What it does accomplish is to convert a big problem (emission of large volumes of air contaminated by harmful levels of gaseous SOx) into a small problem (collection and disposal of scrubber sludge). Dealing with the problem of air pollution is not cheap. An FGD system installed in a newly constructed power plant represents about one-third of the total cost of building the entire plant.

  • It is not only acceptable for people to disagree with you, it is to be expected. Social media lowers the traditional barriers of authority and hierarchy. Never block or delete comments simply because someone disagrees with you. This does not mean you have to engage with such comments. One of the most challenging environ- ments for a parliament using social media is that the nature of comments will often be political, par- ticularly when featuring a controversial piece of legislation or investigation.

  • The key in deciding how to manage media in an organization is to first consider the information, then the media type. The security categorization of the information, along with internal environmental factors, should drive the decisions on how to deal with the media. Again, the key is to first think in terms of information confidentiality, then by media type. In organizations, information exists that is not associated with any categorized system. This information is often hard copy internal communications such as memoranda, white papers, and presentations.

  • The Office of the Assistant Secretary of the Army for Manpower and Reserve Affairs raised a concern that the Army’s use of contractors on the battlefield did not stem from any clearly articulated policy and could well be inappropriate. It asked RAND Arroyo Center to identify the policies and processes that appeared to be driving Army decisions to use contractors on the battlefield and offer ways to increase the likelihood that these policies and processes would yield outcomes consistent with the Army’s high-level goals. Arroyo’s analysis proceeded along two parallel tracks.

  • This paper presents a Bayesian decision framework that performs automatic story segmentation based on statistical modeling of one or more lexical chain features. Automatic story segmentation aims to locate the instances in time where a story ends and another begins. A lexical chain is formed by linking coherent lexical items chronologically. A story boundary is often associated with a significant number of lexical chains ending before it, starting after it, as well as a low count of chains continuing through it.
