  • Very often the process of globalization is referred the word economy evolution. Often we measure and study globalization in the economic relevance. The economy is possibly the most recognized dimension of globalization. That is why we see many new phenomena and processes on economic macro levels and economic sectoral horizons as well as on specific “geography of globalization”. The book The Economic Geography of Globalization consists of 13 chapters divided into two sections: Globalization and Macro Process and Globalization and Sectoral Process. ...

  • A well-known open question is whether every countable collection of Lipschitz functions on a Banach space X with separable dual has a common point of Fr´chet differentiability. We show that the answer is positive for e some infinite-dimensional X. Previously, even for collections consisting of two functions this has been known for finite-dimensional X only (although for one function the answer is known to be affirmative in full generality).

  • This book is motivated to a large extent by our dissatisfaction with current practices in behavioral measurement. Most of the basic data consists of dichotomous responses, and much of the rest is made of responses on short scales. Neither type of data furnishes information that can inherently be considered more than ordinal. The dominant contemporary treatment of this data is to derive from it scores on interval-scale latent variables through the application of one or another"model" that is presumed to explain the data.

  • There have been many proposals to extract semantically related words using measures of distributional similarity, but these typically are not able to distinguish between synonyms and other types of semantically related words such as antonyms, (co)hyponyms and hypernyms. We present a method based on automatic word alignment of parallel corpora consisting of documents translated into multiple languages and compare our method with a monolingual syntax-based method.

  • In an effort to develop measures of discourse levelmanagementstrategies,this study examines a measure of the degree to which decisionmaking interactions consist of sequences of utterance functions that are linked in a decisionmaking routine. The measure is applied to 100 dyadic interactions elicited in both face-to-face and computer-mediated environments with systematic variation of task complexity and message-window size. Every utterance in the interactions is coded according to a system that identifies decision-makmg functions and other routine functions of utterances. ...

  • Universal prevention consists of measures aimed at people that do not have a high risk of disease. Health protection, which falls under this category, is an essential part of prevention that is undervalued and deserves more praise. Universal prevention is not always recognized as such, but it is very important for public health. Innovation is also very important in particular in terms of public information and communication. New digital media will have to be used more than ever in order to reach target groups effectively.

  • A biosensor is a detecting device that combines a transducer with a biologically sensitive and selective component. Biosensors can measure compounds present in the environment, chemical processes, food and human body at low cost if compared with traditional analytical techniques. This book covers a wide range of aspects and issues related to biosensor technology, bringing together researchers from 19 different countries.

  • Trends in needing help with such activities as housework or shopping may be due to changes in the physical abilities of the older population, but they may also be related to the availability of help in the house, either familial or paid, the availability of appliances, and the accessibility of transportation (1, 12). However, causes of trends in IADL functioning have not been apportioned to reasons residing in the person and reasons outside the person. The trends in what is termed ADL disability have not been nearly as consistent as those in IADL disability (31).

  • Process control is recognized as an important means of improving the performance and consistency of thermoplastic parts. However, no single control strategy or system design is universally accepted, and manufacturing systems continue to produce defective components during production. This chapter provides an overview of modeling, measurement, and control strategies in polymer processing, and discusses some of the difficulties posed by their complex and distributed nature.

  • It is crucial that the teaching of writing skills is carried out in a consistent way across the whole school. In a primary setting, this means that all teachers should have reached agreement on the messages about required structure and content that they will give to learners (for example about the layout of a particular genre of writing) so that learners are not confused when they move into a class taught by someone new. In a secondary setting, as learners move between different departments as part of their learning, this is particularly important.

  • A multimeter is a powerful electrical testing tool that can detect voltage levels, resistance levels, and open or closed circuits. It can check both alternating current (AC) and direct current (DC) voltage. Open and closed circuits are indicated by resistance measurements in Ohms. Each computer and networking device consists of millions of circuits and small electrical components. A multimeter can be used to debug electrical problems within a computer or networking device, or with the media between networking devices....

  • The effect of HNC on air quality is measured using hourly air pollution records from monitoring stations. Pollution levels are compared before and after the restrictions for five major pollutants with levels in previous years acting as a comparison group to control for seasonal variation. The analysis controls for possible confounding factors by restricting the sample to a relatively narrow time window around the implementation of HNC and by using a regression discontinuity design. Across pollutants and specifications there is no evidence that the program has improved air quality.

  • The distance measure consists of three dummy variables:7 The first indicates diary weeks starting on payday, and weeks starting 1 to 7 days after payday. The second indicates weeks starting 8 to 14 days after payday. Diary weeks beginning at distances 15 to 22 are omitted from the equation and serve as the reference category. The third dummy indicates weeks beginning 4 to 1 days before the next payday. These weeks overlap the (imputed) next payday by at least three days.
