  • Analytical expression for the Displacement-displacement Correlation Function (DCF) C R has been derived based on the derived Mean Square Relative Displacement (MSRD) σ and the Mean Square Displacement (MSD) u for fcc 2 2 crystals. The effective interaction potential of the system has been considered by taking into account the influences of nearest atomic neighbors, and it contains the Morse potential characterizing the interaction of each pair of atoms.

  • Emphasis on effect sizes is a rapidly rising tide as over 20 journals in various fields of research now require that authors of research reports provide estimates of effect size. For certain kinds of applied research it is no longer considered acceptable only to report that results were statistically significant. Statistically significant results indicate that a researcher has discovered evidence of a real difference between parameters or a real association between variables, but it is one of unknown size.

  • Analytical expressions for the Morse potential parameters of diamond crystals have been derived. They contain the energy of sublimation, the compressibility and the lattice constant. Numerical calculations have been carried out for Si and Sn, and the results reflect fundamental properties of this potential. The obtained Morse potential parameters have been used for calculation of the anharmonic correlated effective potentials of these crystals in XAFS theory showing clearly anharmonic effects . ...

  • This paper explores the relationship between the translation quality and the retrieval effectiveness in Machine Translation (MT) based Cross-Language Information Retrieval (CLIR). To obtain MT systems of different translation quality, we degrade a rule-based MT system by decreasing the size of the rule base and the size of the dictionary. We use the degraded MT systems to translate queries and submit the translated queries of varying quality to the IR system. Retrieval effectiveness is found to correlate highly with the translation quality of the queries.

  • The advantages and limitations of conventional structural MRI for the diagnosis and monitoring of MS are discussed by Andreadou (Chapter 15). There is often a disparity between the level of structural abnormality seen on MRI and level of cognitive difficulties expressed by the patient with MS. Clinical interview and neuropsychological assessment are vitally impairment, not only from an initial diagnostic perspective but also in terms of longer term planning and care.

  • THE EFFECTS OF CUSTOMER LOYALITY ON PROFITABILLITY Chapter Three turns to a wholly different, but not unrelated, topic, the role of admissions exam scores in the identification of well-prepared students in the college admissions process. The case for using such exams is often made with “validity” studies, which estimate the correlation between test scores and eventual collegiate grades, both with and without controls for high school grade point average. I argue that there are two fundamental problems with these studies as they are often carried out.

  • We also examine the determinants of the return gap. We find that estimated trading costs are negatively related to the return gap. Also, most funds in our sample exhibit relatively large correlations between the hypothetical holdings returns and the investor returns, indicating that their actual investment strategies do not differ significantly from their disclosed strategies. However, some funds have relatively low correlations between holdings and investor returns.

  • One finds that there is a positive correlation between a country’s level of development and insurance coverage. Developed countries tend to have better developed and well- functioning insurance services sectors both domestically and in terms of insurance exports, as compared to developing countries. This is perhaps most evident when one compares the share of industrialized countries in the world insurance markets, which in 2004 stood at 88.5 per cent as compared with 11.4 per cent for emerging markets, the majority of which are developing countries.

  • While there appears to be a rising incidence of problem drinking in the elderly, there are also reports that low risk drinking may provide benefits to older populations. Indeed. arguably most of the supposed benefits of alcohol consumption are to be found in older people. So, for example, the claimed protective effect of alcohol in regard to cardiovascular disease applies to the late middle aged and elderly. For this reason, the recommended optimum level of alcohol consumption for health is higher for the elderly than the young.

  • While a filter ismatched against a single notification based on the notification’s attribute values, a pattern is matched against one or more notifications based on both their attribute values and on the combination they form. At its most generic, a patternmight correlate events according to any relation. For example, the programmer of a stockmarket analysis toolmight be interested in receiving price change notifications for the stock of one company only if the price of a related stock has changed by a certain amount.

  • Learning how to compose an effective extended text, therefore, should be conceived as a task similar to acquiring expertise in related culturally acquired domains. It is not merely an extension of our apparent biological predisposition to acquire spoken language. Rather, it is more similar to learning how to type - which is in fact one aspect of composition, as a common means of motor output. Or, it is similar to learning how to play chess - which is another planning intensive task similar to composition in its demands on thinking and memory. Or, it is similar to learning...

  • Marketers are being challenged by a deluge of data that is well beyond the capacity of their organizations to comprehend and use. Their strategies are not keeping up with the disruptive effects of technology-empowered customers; the proliferation of media, channel, and customer contact points; or the possibilities for microsegmentation. Closing the widening gap between the accelerating complexity of their markets and the limited ability of their organizations to respond demands new thinking about marketing capabilities.

  • This study has focused on cardio-respiratory illnesses caused by the principal components of smog, namely ozone and air-borne particulate matter. 2 Smog consists of a complex “soup” of pollutants, some of which may cause human health problems directly and others which may be precursors to causal contaminants or which are closely correlated with causal contaminants and hence act as “markers” for human health risks. The complexities associated with the cause/effect relationships between this soup of pollutants and human health are explored in this report.
