The proportion of adults aged 60 years and older is increasing globally; it stands at 12% in the global population and is projected to double by 2050, with a more pronounced increase in high-income countries1,2. The ageing of populations presents health and social care challenges due to incr...
Changes in values of those functions can be investigated via decomposition by the factors of influence as well. 4. Numerical Examples To illustrate the described approach in numerical estimations, let us consider a set of ten products sold at a market in two consecutive time periods. For example...
Other exogenous factors relevant for the prediction of economic output are purposefully assumed constant. A Monte Carlo procedure that samples from climate model projections, empirical models with different numbers of lags and model parameter estimates (obtained by 1,000 block-bootstrap resamples of ...
The results of the crash occurrence model showed that the drivers' factors (gender, nationality and years of experience in driving), location and surrounding condition factors (non-junction locations, light and road surface conditions) and roads feature (road type, number of lanes and speed limit...
R Bejarano,TD Hackenberg - 《Journal of the Experimental Analysis of Behavior》 被引量: 13发表: 2007年 Factors significantly related to science achievement of Malaysian middle school students: An analysis of TIMSS 1999 data The importance of science and technology in the global economy has led to...
trends of actual NPP, potential NPP and HNPP (human appropriation of NPP, the difference between potential NPP and actual NPP) were used to analyze the desertification dynamic and calculate the relative roles of climate change, human activities and a combination of the two factors in ...
For an understanding of factors leading to economic growth in various regions, the seminal contribution of Solow(1956), which constitutes the very foundation of the development of the neoclassical growth model, is at the forefront of public policy discussions. Solow (1956)’s analysis demonstrated ...
In order to find the sum of n terms of a series, each term of which is composed of r factors in arithmetical progression or composed of the reciprocal of the product of r factors in arithmetical progression, the first factor of the terms being the same, A.P. for such type of series ...
of release, dispersal, transformation and bio-uptake processes that link Hg sources to Hg exposure. Global change interacts with the Hg cycle by impacting the physical, biogeochemical and ecological factors that control these processes. In this review we examine how global change such as biome ...
However, “relative” leaves room for change: research into value change suggests that value change after childhood is possible, and that these changes could be attributed to a host of factors. Schwartz28 mentions 3 potential sources of value change in adults: 1; societal events like war, ...
