Meta-analysis (MA) is the quantitative integration of empirical studies that address the same or similar issues. It provides overall estimates of effect size, and can thus guide practical application of research findings. It can also identify moderating variables, and thus contribute to theorybuilding and research planning. It overcomes many of the disadvantages of null hypothesis significance ...

To understand the performance of a sensor or make a choice between different sensors for a detection task it is important to have an understanding of how the recorded signals are generated. In the case of sensing ionizing radiation, signals are generated after the incoming radiation has undergone interactions within the sensor material. The types of interactions and the subsequent resultant par...

in the introductory stages of language learning, students are exposed to parative forms explicitly taught in their textbooks. as knoch (2004) mthis is accomplished by teaching the comparative form of the adjective generally directly followed by a than clause. this study aimed to compare between native and nonnative material developers with regard to the coverage of comparative forms. in doing s...

Abstract Although Joule’s experiment on the mechanical equivalent of heat is well known and discussed in many introductory physics courses textbooks, we are not aware any version this that can be set up by lecturers or teachers using standard laboratory equipment. To fill gap, present a setup quite similar to original show what kind quantitative results obtained with it. It will shown temperatu...
