The Cloud Profiling Radar is the key science instrument for the CloudSat Mission to acquire a global data set of vertical atmospheric cloud structure and its variability. CPR is a 94-GHz nadir-looking radar that measures the power backscattered by clouds as a function of distance from the radar. This sensor is expected to provide cloud measurements at a 500-m vertical resolution and a 1.5-km ho...

The purpose of this study is to develop and validate an instrument to measure organizational IT. We adopted the resource-based view (RBV) of the firm and the dynamic capabilities theory to propose the Dynamic IT Capability (DITC) instrument. Dynamic IT Capability is defined as the ability to integrate, build, and reconfigure IT-based resources and competencies to adjust to rapidly-changing envi...

Although there is no agreement as to what instructional interactivity and interaction mean in educational literature, researchers agree that both terms are vital for teaching and learning one way or another. This paper presents the item-development stages and validity and reliability analyses of the Interactivity Survey (IS), which attempts to uncover the perceptions of professors working at de...

Cell death as a phenomenon in embryonic development was first described over 100 years ago. Approximately 30 years ago the process was named apoptosis, and its involvement is now recognized in many life processes, in virtually every animal species, and from fertilization to the death of an organism. In cardiovascular development, it coincides with major developmental processes in specific time ...

Background: Sand production is an important factor affecting reservoir exploitation. Excessive sand production affects the oil well life, causes the damage to the oil recovery device and brings serious hidden danger in the process of safety production. Objective: This paper presents a sand content computation model for the crude oil, which uses the power of sand production and Parseval theorem,...

Self-efficacy is an important trait that factors into a teacher’s ability to effectively teach writing. Teacher’s self-efficacy in writing, however, has been widely ignored by the writing research community. This study developed a new instrument to measure a teachers’ writing self-efficacy and examined its psychometric properties. The Writing Self-Efficacy Instrument demonstrated factorial scor...

Currently there is no standardized, quantitative measure of the reticence construct created by Phillips (1965, 1984, 1986). Critics (e.g., Glaser, 1981) have argued that this has made it difficult to compare findings across studies of reticence as well as to establish the effectiveness of skills training programs such as the rhetoritherapy program Phillips developed for the treatment of reticen...
