optimum sample size is an essential component of any research. the main purpose of the sample size calculation is to determine the enough number of units needed to detect the unknown clinical parameters or the treatment effects or the association after data gathering. it is not uncommon for studies to be underpowered and failing to detect the existed treatment effects due to inadequate sample s...

We present extensive evaluations comparing the performance of taxonomy-based and corpus-based approaches on SimLex999. The results confirm our hypothesis that taxonomy-based approaches are more suitable to identify similarity. We introduce two new measures of evaluation that show that all measures perform well on a coarse-grained evaluation and that it is not always clear which approach is most...

Although we live in a modern world dominated in many ways by the rationality of science and technology, age-old millennial beliefs in the supernatural, good and evil, a coming apocalyptic upheaval, and a day of judgment are still widely held throughout the world. Even among non-religious people, similar beliefs exist, especially in political ideologies. Focusing on evil, I contend that most evi...

Recent work on metacognition indicates that monitoring is sometimes based itself on the feedback from control operations. Evidence for this pattern has not only been shown in adults but also in elementary schoolchildren. To explore whether this finding can be generalized to a wide range of age groups, 160 participants from first to eighth grade participated in a study based on a self-paced stud...

Intelligent demand-side management represents a future trend of power system regulation. A key issue in intelligent demand-side management is accurate prediction of load within a local area grid (LAG), which is defined as a set of customers with an appropriate residential, commercial and industrial mix. Power consumption is deemed to be unpredictable in some sense due to the idiosyncratic behav...

The challenge of combining research and practice in HRD has led to continuing debate on who are scholar-practitioners and how they integrate research and practice in the workplace. This qualitative collective case study provides insights from seven scholar-practitioners to help HRD professionals and researchers understand implementation concerns of scholar-practitioners. The findings reveal sch...

Meta-analysis, a statistical tool for combining results across studies, is becoming popular as a method for resolving discrepancies in genetic association studies. Persistent difficulties in obtaining robust, replicable results in genetic association studies are almost certainly because genetic effects are small, requiring studies with many thousands of subjects to be detected. In this article,...

OBJECTIVES To examine the extent of variation in public health agency spending levels across communities and over time, and to identify institutional and community correlates of this variation. DATA SOURCES AND SETTING Three cross-sectional surveys of the nation's 2,900 local public health agencies conducted by the National Association of County and City Health Officials in 1993, 1997, and 20...

When Orville Wright flew his airplane over a small stretch of rolling grassland in 1903, the managing editor of Scientific American predicted that thousands of planes would soon fly over every city, delivering patrons to theaters. On the eve of the First World War, two famous British aviators argued that planes would prevent wars in the future (because they brought people together). Scientists,...
