Relations between morphological characteristics, assessed by 15 morphological measures, and motor abilities, assessed by 24 motor tests, were investigated on the total cross-sectional sample of 400 male participants from Slovenia (200 boys of 7 and 200 boys of 9 years). Associations between these two groups of variables were determined by the Hotteling's biorthogonal canonical correlation analy...

This study investigated the within-day repeatability and between-subject variation of vector coding variability during treadmill running. The lower-limb kinematics of eight male triathletes running at 12 km/h were captured twice on the same day. Mean coupling angle variability across the stride cycle was computed for 20 couplings using the modified vector coding technique. Between-subject varia...

The average level and cross-sectional variability of fund alphas are estimated from a large sample of mutual funds. This information is incorporated, along with the usual regression estimate of alpha, in a (roughly) precision-weighted average measure of individual fund performance. Substantial ‘‘learning across funds’’ is documented, with significant effects on investment decisions. In a Bayesi...

Available online 23 October 2015 We explain stable growth performance in democracies by characterizing political systems in terms of the distribution of political power across groups, and show when the qualities of policy alternatives are uncertain, greater democracy (decentralization of authority) leads to more stable policy choices. We empirically test this mechanism by creating measures of t...

We examined the interactive influence of specific demographic and diagnostic variables on Benton Visual Retention Test (BVRT) performance in three commonly presenting groups of older adults. Cross-sectional data from three archival samples were utilized: “normals” (n = 156), “normals with memory concerns” (n = 435), and a “mixed neurologic” group (n = 196). In both normal groups, as well as in ...

Neurodegenerative diseases such as Alzheimer's disease present subtle anatomical brain changes before the appearance of clinical symptoms. Large longitudinal brain imaging datasets are now accessible to investigate these structural changes over time. However, manual structure segmentation is long and tedious and although automatic methods exist, they are often performed in a cross-sectional man...

OBJECTIVE To investigate how affordable cigarettes are in developed and developing countries, and to calculate by how much the affordability of cigarettes has changed between 1990 and 2001; and secondly, to investigate the relation between cigarette affordability and consumption. DESIGN Affordability was defined as the cost of cigarettes relative to per capita income. Trends in cigarette affo...

The relative costs of trading different goods vary independently of the relative costs of producing them. The costs of trade are also often high. As a result, producer price elasticities of demand in economies that trade are usually much lower than purchaser price elasticities. Trade costs could thus explain why cross-country variation in the composition of output is much less sensitive to vari...

The last decade has been witness to phenomenal growth in endodontic technology. The introduction of these new technologies has resulted in endodontics becoming easier, faster and most importantly, better. Principal among these is Nickel Titanium (NiTi) rotary instrumentation that results in consistent, predictable, and reproducible shaping. The purpose of this article is to review the design fe...

One of the determining factors of the quality of Web search engines is the size of their index. In addition to its influence on search result quality, the size of the indexed Web can also tell us something about which parts of the WWW are directly accessible to the everyday user. We propose a novel method of estimating the size of a Web search engine’s index by extrapolating from document frequ...
