Human female reproductive aging consists of multiple processes and interacts with other physiological systems in unique ways. Here we discuss eight recent longitudinal, epidemiologic studies of female reproductive aging that include endocrine data to highlight their contributions to our understanding of these various aging processes and their interactions. Specifically, we review data on ovaria...

One way that firms have adapted to competitive pressures in today’s global marketplace is to use asynchronous communication technologies to support virtual project teams. To better understand the effectiveness of these dispersed teams, we compare the asynchronous communication transcripts of high and low performing virtual teams working on the early stages of software design. We also compare th...

To better understand the potential for horizontal surfaces in day-to-day work, we conducted a field study. We collected and analyzed over a month of use data from eight participants who used horizontal displays in conjunction with their existing office computer setups. Our analysis of the system logs, observations, and interview data from the study reveals clear differences in preference and us...

Experiments using quantitative real-time PCR to test hypotheses are limited by technical and biological variability; we seek to minimise sources of confounding variability through optimum use of biological and technical replicates. The quality of an experiment design is commonly assessed by calculating its prospective power. Such calculations rely on knowledge of the expected variances of the m...

Sex and gender have been demonstrated to influence all domains of health, from basic mechanisms of disease development to health service utilization. It is therefore no longer acceptable to ignore sex and gender issues in health research reports if these reports are to be deemed accurate. Funding agencies and journals have been identified as primary change agents in health research systems. Can...

There are many guides on proper psychology, but far fewer on interesting psychology. This article presents six guidelines for interesting research. The first three-Phenomena First, Be Surprising, and Grandmothers, Not Scientists-suggest how to choose your research question; the last three-Be The Participant, Simple Statistics, and Powerful Beginnings-suggest how to answer your research question...

Bioprocess development is very labor intensive, requiring many experiments to characterize each unit operation in the process sequence to achieve product safety and process efficiency. Recent advances in microscale biochemical engineering have led to automated experimentation. A process design workflow is implemented sequentially in which (1) a liquid-handling system performs high-throughput we...
