Résumé
Welcome to the second annual presentation of the of the Best Business Websites (Free Resources). These three websites were selected by the Business Reference and Services Section (BRASS) Education Committee, which is a part of RUSA. The committee is responsible for compiling and selecting the best free online resources to meet business librarians' needs in serving their user populations. This year's selection deals with one site from financial markets and investments and two from international business. We hope you find the following sources helpful and encourage you to explore all of our other picks at the RUSA BRASS website (www.ala.org/rusa/brass). Additionally useful are the Selected Core Resources, also found on the section website. FINANCIAL MARKETS AND INVESTMENTS BigCharts.com, http://bigcharts.marketwatch.com The name says it all: BigCharts.com is big on charts! This site provides basic, advanced, and interactive charting tools; current and historical quotes; industry and market data; news and analysis; and screening tools for stocks listed on major American, Canadian, and other exchanges around the world. BigCharts.com is operated by MarketWatch, a leading multimedia source of financial news and information. The website organizes information under tabs such as quotes, news, industries, markets, historical quotes, and big reports. A help link at the bottom of the screen leads to detailed information on how to use various sections of the site and to a glossary. Creating a one-year price chart is easy: enter a ticker symbol and click on Basic Chart, a blue button at the top of the page. To change the timeframe, use the dropdown menu that offers intraday and historical time series. You can build charts for periods ranging from one day to a decade, or even longer if the data are available for that security. The historical quotes are available from 1994 to present. Charts for up to ten days use intraday data and the longer time series use end-of-day pricing provided by Thomson Reuters. The charts for stocks traded on American exchanges are accompanied by links to related company and market adviser news, industry data, company profile, annual report, SEC filings, insider news and data, and analyst ratings. Advanced charts offer a long list of charting options and allow customization to one's exact specifications. You can select start and end dates; compare up to ten stocks, mutual funds or indexes on a single chart; overlay moving averages and fundamental information on the chart price display; and view up to three of the twenty-seven available technical indicators at one time. The interactive charts offer all the advanced chart features and more, including the ability to draw trend lines by selecting a timeframe and then zooming in on a specific timeframe on the chart. Use the section to track up to fifty intraday quotes at a single time. There are two areas within this section: My Favorite Quotes and Quick Quotes. Both offer basic intraday price information for each stock with links to news and charts for further research. The My Favorite Quotes page allows you to save your tickers for future visits to the page. The Markets section provides a summary on current day's domestic stock market activity.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
