research is one of the most important ways of science production (1). the purpose of research is exploring the unknown and explaining the variables that affect the human life. in the health sciences the purpose of which is health promotion, research is valued as much as human life (2). in many scientific texts, there is an emphasis on the importance of health researches in the quality of human ...

work consciousness meaning to perform tasks without close supervision has three main factors: individual, work itself, and administration. individual needs, drives, motives, attitudes, and personalities interact with job- related factors such as organizational climate and meaningfullness. the result is observed behavior. administration- the third main factor- should match to other two factors b...

1. List the percentage of children who drop out of school and have undetected disabilities or known environmental risk factors. 2. Describe the ways in which early intervention is effective. 3. Delineate methods of detecting disabilities and development delays. 4. Describe the percentage of children in whom assessment tools can detect disabilities correctly. 5. Determine how often children shou...

We study the distribution of divisors of Euler’s totient function and Carmichael’s function. In particular, we estimate how often the values of these functions have ”dense” divisors.

Recent research has examined how often mind-wandering occurs about past vs. future events. However, mind-wandering may also be atemporal, although previous investigations of this possibility have not yielded consistent results. Indeed, it is unclear what proportion of mind-wandering is atemporal, and also how an atemporal response option would affect the future-oriented bias often reported duri...

Physics laboratory courses have been generally acknowledged as an important component of the undergraduate curriculum, particularly with respect to developing students’ interest in, and understanding of, experimental physics. There are a number of possible learning goals for these courses including reinforcing physics concepts, developing laboratory skills, and promoting expertlike beliefs abou...

Logistics distributors face the issue of having to provide increasing service levels while being forced to reduce costs at the same time. Same-day delivery, quick order processing and rapidly growing ranges of articles are only some of the prevailing challenges. One key aspect of the performance of an intra-logistics system is how often and in which amplitude congestions and dysfunctions affect...

Microcrystallography Crystals of proteins and other biological macromolecules never grow very big, due to the “soft” nature of the molecules and the weakness of the forces holding them together. At CHESS and other synchrotron sources, it is routine to deal with crystals that are ~100 μm across, but how often do we need to work with even smaller crystals? Ithaca High School student Sarah Kim, un...

There is absolutely no doubt in the minds of the authors of the Aves Report that volunteers are an essential ingredient of the expanding Social Series. But the questions of how, where, and?per-haps most important?why, they are used is the burden and crux of the message. Whilst recognising that enthusiasm and spontaneity are the great contribution of voluntary porkers, there is a practical recog...
