  • Given the enormous, ever-growing, and constantly-changing size, shape, and consistency of the internet and the use that is made of it means that methodological issues abound when attempting to produce measurements of traffic and content. Yet even given the limitations of the data available, Envisional believes that the estimates produced in this report are more accurate than any that have been published before.

  • Within the framework of translation knowledge acquisition from WWW news sites, this paper studies issues on the effect of cross-language retrieval of relevant texts in bilingual lexicon acquisition from comparable corpora. We experimentally show that it is quite effective to reduce the candidate bilingual term pairs against which bilingual term correspondences are estimated, in terms of both computational complexity and the performance of precise estimation of bilingual term correspondences.

  • In May 2010, the World Health Assembly (WHA), through resolution WHA63.14, endorsed a set of recommendations on the marketing of foods and non-alcoholic beverages to children. The main purpose of the recommendations was to guide efforts by Member States in designing new policies, or strengthening existing policies, on food marketing communications to children in order to reduce the impact of marketing foods high in saturated fats, trans-fatty acids, free sugars, or salt. Resolution WHA63.

  • A second criterion for meaningful research on cross-language transfer is the recognition that literacy comprises many component skills. The component skills of reading must be carefully assessed in the first and second language to trace the development of first- and second-language abilities in relation to one another.

  • Even healthy people can be affected by air pollution. Air pollution can affect anyone. Healthy teenagers, young adults, and strong athletes can suffer negative effects from high pollution levels, especially when exercising outdoors. People who live in heavily polluted areas are exposed to not just one pollutant but to many pollutants. And, the concentration of each pollutant changes during the day. All of this makes it difficult to separate out the effects of each pollutant. In addition, how susceptible people are to the effects of air pollutants can vary widely.

  • Despite the different methods used, the results of the three countries are similar, especially concerning PM10 levels caused by road traffic. The differences in total PM10 can be explained by the fact that (a) the background concentration is higher in Central and Eastern Europe than in the Western parts of Europe and (b) for Switzerland, large areas at higher altitudes have significantly lower PM10 levels. Furthermore, the sulphate fraction of the background concentration may increase from Western to Eastern Europe, resulting in an increase of the non-traffic related PM10 fraction.

  • Contributing approximately 300,000 jobs and 4% of the GDP, tourism ranks as the fourth-largest export industry of Switzerland, and is known universally as the largest industry. Growth in tourism organisations abroad and in Switzerland, combined with increasingly complex projects underway in Eastern Europe, India, China and other emerging destinations, open up a wide range of perspectives in tourism- related organisations for highly trained graduates holding a Master’s degree.

  • Both versions of synthesis allow inclusion and estimation of spawner-recruitment functions. When detailed age composition data are lacking, the estimated spawner-recruitment curve can be used to generate the entire time series of recruitments, thus turning synthesis into a simple production model. At the other extreme, inclusion of the spawner-recruitment curve in data-rich models allows estimation of this curve while taking into account all available information.

  • Both the definition of poverty and the poverty thresholds have been criticized on grounds that they do not accurately reflect families true financial resources, nor the amount of money families actually need to be economically self-sufficient. 20 Estimates of minimum income levels required for families to achieve basic economic self-sufficiency range around twice the federal poverty thresholds. 21 Based on the official poverty definitions, in 2007 (the latest year for which data are available), 37.3 million people (12.

  • From January 1 to May 9, 2008, 61,459 HFMD cases and 36 deaths were reported through the disease reporting system in Mainland China. The number of reported cases increased sharply after the disease became notifiable on May 2, and with cases being reported from nearly all provinces. The 5 provinces with the highest number of reported cases are Guangdong (11,374), Anhui (9,235), Zhejiang (6,134), Shandong (4,566) and Henan (3,230).

  • There is an adjustable feedback from the main valve to the pilot valve to adjust the ratio of main valve to pilot valve movement. By changing the amount the main valve moves for a given movement of the pilot valve, the relative speed of the servomotors is changed. This is independent of the setting for wicket gate travel rate. The main valve normally doesn’t move far enough to contact the stop nuts during a load change. The feedback acts on the pilot valve bushing to close off the pilot valve ports to stop the flow of oil...

  • Fairly large proportion of patients attending for the first time the Chest Clinics in India have had anti-tuberculosis chemotherapy for some time though irregularly. The assessment of the prevalence of Initial Drug Resistance (IDR) among these patients will be of great value in their management and also in formulating general policies of treatment in the Chest Clinics under the National Tuberculosis Control Programme.

  • A superstructure can be thought of as the conduit which carries a roadway over a crossing. Like any other bridge component, the superstructure is comprised of many elements. In the bridge design profession, no other component elicits so much discussion, and even downright controversy, as to the type of elements to be utilized in construction. The structural and geometric complexities of the superstructure component make it one of the most challenging design problems in a bridge engineering project....

  • More Topics in Linear Unobserved E¤ects Models This chapter continues our treatment of linear, unobserved e¤ects panel data models. We first cover estimation of models where the strict exogeneity Assumption FE.1 fails but sequential moment conditions hold. A simple approach to consistent estimation involves differencing combined with instrumental variables methods.
