Big data analytics often involves complex join queries over two or more tables. Such join processing is expensive in a distributed setting both because large amounts of data must be read from disk, and because of data shuffling across the network. Many techniques based on data partitioning have been proposed to reduce the amount of data that must be accessed, often focusing on finding the best ...

Software is invisible, disappearing into les on disks. The invisible nature of software contributes to low programmer productivity by hiding system complexity, particularly for large team-oriented projects. Visualization can help software engineers cope with this complexity and thereby increase programmer productivity. We describe four innovative visual representations of software that scale to...

Allochronic divergence, like spatial isolation, may contribute to population diversity and adaptation, however the challenges for tracking habitat utilization in shared environments are far greater. Adult Klukshu River (Yukon, Canada) sockeye salmon, Oncorhynchus nerka, return as genetically distinct "early" and "late" runs. Early and late adult spawning populations (1999 and 2000) and their su...

The TPC has been tested with cosmic rays in July and November, 1981. It is now installed at IR2 at PEP and has been operating in 14 GeV e+ebeams for about a week. Preliminary analysis of the cosmic ray data yields spatial resolutions of axY = 260 !J and ox = 650 p, at a pressure of 8.6 atm. Results are also reported at 4.0 and 1.5 atm. The operation with e+ebeams is good. No problems with posit...

Animal selection for genetic improvement of productivity may lead to an increase in inbreeding through the use of techniques that enhance the reproductive capability of selected animals. Therefore, breeding strategies aim to balance maintaining genetic variability and acceptable fitness levels with increasing productivity. The present study demonstrates the effectiveness of genomic-based optimu...

A …rm’s productivity depends on how production is organized given the level of demand for its product. To capture this mechanism, we develop a theory of an economy where …rms with heterogeneous demands use labor and knowledge to produce. Entrepreneurs decide the number of layers of management and the knowledge and span of control of each agent. As a result, in the theory, heterogeneity in deman...

Transiently Powered Computers (TPCs) are novel devices that are battery-less and operate using only ambient energy. Therefore TPCs are prone to frequent power interruptions, and such the need for developing TPC-centric algorithms is a necessity. We advocate that only through a common experimental environment, accessible to everyone, a proper comparison of newly developed algorithms for TPCs can...

For a general class of infinite data structures including streams, binary trees, and the combination of finite and infinite lists, we investigate the notion of productivity. This generalizes stream productivity. We develop a general technique to prove productivity based on proving context-sensitive termination, by which the power of present termination tools can be exploited. In order to treat ...

BACKGROUND Job stress and job satisfaction are important factors affecting workforce productivity. This study was carried out to investigate the job stress, job satisfaction, and workforce productivity levels, to examine the effects of job stress and job satisfaction on workforce productivity, and to identify factors associated with productivity decrement among employees of an Iranian petrochem...

This paper compares the e¢ ciency implications of aggregate output equivalent unit versus advalorem tax regimes when monopolistically competitive …rms produce di¤erentiated products with either homogenous or heterogenous costs. The model allows for …rms to price at a variable markup over marginal cost. In line with most prior …ndings the superiority of ad-valorem tax continues to hold when …rms...
