  • The revised and updated Second Edition includes new subchapters on evolutionary Blackman-Tukey, Lomb-Scargle and Wavelet powerspectral analyses (Chapters 5.6 – 5.8), statistical analysis of point distributions and digital elevation models (Chapters 7.9 and 7.10), and a new chapter on the statistical analysis of directional data (Chapter 10). Whereas undergradu- ates participating in a course on data analysis might go through the entire book, the more experienced reader will use only one particular method to solve a specifi c problem.

  • We study distributional similarity measures for the purpose of improving probability estimation for unseen cooccurrences. Our contributions are three-fold: an empirical comparison of a broad range of measures; a classification of similarity functions based on the information that they incorporate; and the introduction of a novel function that is superior at evaluating potential proxy distributions.

  • Distributional word similarity is most commonly perceived as a symmetric relation. Yet, one of its major applications is lexical expansion, which is generally asymmetric. This paper investigates the nature of directional (asymmetric) similarity measures, which aim to quantify distributional feature inclusion. We identify desired properties of such measures, specify a particular one based on averaged precision, and demonstrate the empirical benefit of directional measures for expansion.

  • We focus on the impact of two main policy changes: first, the increase in the rice export quota and the significant increase in the price of rice, especially in the south; second, liberalization of the fertilizer market and the sharp drop in the price of fertilizer. To this end, we document changes in the empirically observable “institutional environment,” exploring changes in rice and other crop prices as well as fertilizer prices.

  • The ability to detect similarity in conjunct heads is potentially a useful tool in helping to disambiguate coordination structures - a difficult task for parsers. We propose a distributional measure of similarity designed for such a task. We then compare several different measures of word similarity by testing whether they can empirically detect similarity in the head nouns of noun phrase conjuncts in the Wall Street Journal (WSJ) treebank.

  • This paper presents results from experiments in automatic classification of animacy for Norwegian nouns using decision-tree classifiers. The method makes use of relative frequency measures for linguistically motivated morphosyntactic features extracted from an automatically annotated corpus of Norwegian. The classifiers are evaluated using leave-oneout training and testing and the initial results are promising (approaching 90% accuracy) for high frequency nouns, however deteriorate gradually as lower frequency nouns are classified.

  • This article presents empirical evaluations of aspects of annotation for the linguistic property of animacy in Swedish, ranging from manual human annotation, automatic classification and, finally, an external evaluation in the task of syntactic parsing.

  • This volume is part of a multiyear research program on Behavioral Responses to Taxation that is being conducted under the auspices of the National Bureau of Economic Research (NBER). This project draws together researchers with a wide range of interests in tax policy issues. The development and mainte- nance of the NBER TAXSIM program, a detailed computer algorithm for com- puting household tax liabilities under actual and various alternative tax re- gimes, is one of the centerpieces of this research project. Many of the research studies...

  • TWO ESSAYS IN INTERNATIONAL ECONOMICS: AN EMPIRICAL APPROACH TO PURCHASING POWER PARITY AND THE MONETARY MODEL OF EXCHANGE RATE DETERMINATION I adopt a different strategy: I compare housing markets that differ in the strength of the residential location-school assignment link, and I develop simple reduced-form implications of parental valuations for the across-school distribution of student characteristics and educational outcomes as a function of the strength of this link.

  • The chapter concludes with a discussion on the implications of all these changes for the veterinary sector and offers some suggestions for future research. Thus, the authors lay the theoretical foundation for future empirical work in this field by debating some key concepts and generating hypotheses for future study.

  • Banking sector reforms have been sequenced to correspond with changing regulations of the foreign exchange market. The government has allowed the exchange rate to gradually float (as opposed to a “crawling” peg), and full current account convertibility has been introduced, with de facto capital account convertibility for nonresidents, and calibrated liberalization for residents.

  • The current RSS polling mechanism has been said to scale well because “its cost is almost directly propor- tional to the number of subscribers” [5]. In fact, linear cost is typically an indicator of poor scaling properties, especially when that cost is focused on one member of a distributed system. It is likely that the further growth of RSS adoption will be badly stunted, without substantial change to the way micronews is distributed.

  • The book MATLAB Recipes for Earth Sciences is designed to help under- graduate and PhD students, postdocs, and professionals to fi nd quick solu- tions for common problems in data analysis in earth sciences. The book provides a minimum amount of theoretical background, but then tries to teach the application of all methods by examples. The software MATLAB is used since it provides numerous ready-to-use algorithms for most meth- ods of data analysis, but also gives the opportunity to modify and expand the existing routines and even develop new software.

  • We propose a two-step inversion of three-component seismograms that ( 1) recovers the far-field source time function at each station and (2) estimates the distribution of co-seismic slip on the fault plane for small earthquakes (magnitude 3 to 4). The empirical Green’s function (EGF) method consists of finding a small earthquake located near the one we wish to study and then performing a deconvolution to remove the path, site, and instrumental effects from the main-event signal.

  • Our feature films are currently the source of a substantial portion of our revenue. We derive revenue from our distributors’ worldwide exploitation of our feature films in theaters and in ancillary markets such as home entertainment, digital and pay and free broadcast television. In addition, we earn revenue from the licensing and merchandising of our films and characters in markets around the world.

  • Andrei Nikolaevich Kolmogorov (Tambov 1903, Moscow 1987) was one of the most brilliant mathematicians that the world has ever known. Incredibly deep and creative, he was able to approach each subject with a completely new point of view: in a few magnificent pages, which are models of shrewdness and imagination, and which astounded his contemporaries, he changed drastically the landscape of the subject. Most mathematicians prove what they can, Kolmogorov was of those who prove what they want....

  • Indigenous literature on the topic of Indigenous medicine emphasizes the ties to land, language, and culture. The natural environment shapes the medical expertise and practices employed by each Indigenous group. For example, the Hopi knowledge of medicine for venomous snakebites would likely not be known or practised in the Northwest Territories; similarly, the Hopi might not have developed any medicines for frostbite. Battiste and Henderson articulate the cultural approach to knowledge applied by Indigenous people.
