The value of a study relies heavily on the quality of data collection and analysis. No matter the skill level of the researchers or what journal the study is published in, poor collection and management of data result in a poor study. Our personal experiences and impressions of collecting, storing, protecting, and retrieving data for a U.S.…

In recent decades, the governance of educational systems has experienced dramatic changes in many countries. Schools have been given more autonomy whilst being held increasingly accountable at the central level through standardized testing and other forms of external evaluation. The mechanisms of performance-based accountability (PBA) and the…

This study aims to synthesize research trends of blended language learning studies over the past two decades, from 2000 to 2019. Data were collected from the Web of Science, and a total of 60 SSCI-indexed journal articles were retrieved for bibliometric synthesis. Drawing on the revised technology-based learning model, participants, learning…

This paper is designed to explore the current status of Chinese EFL teachers' use of digital resources in doing research and its influential factors. It classifies digital resources into six types aligned to the research process and uses the revised TAM to find out and explain its influential factors. A total of 180 teachers were investigated via…

Knowledge of collocations is essential for English academic writing. However, there are few academic collocation referencing tools available and there is a pressing need to develop more. In this paper, we will introduce the ACOP (Academic Collocations and Phrases Search Engine), a newly developed corpus-based tool to search large academic corpora.…

The launch of HealthCare.gov, the website of the Affordable Care Act (AKA Obamacare), was a major public relations disaster for the Obama administration. This case examines some of the factors that contributed to the failure of the launch and then details how Optum, an information technology service provider, considered the opportunity provided by…

Lifestyle choices are attributed to 40% to 60% of adult peak bone mass. The National Osteoporosis Foundation (NOF) sought to update its 2000 consensus statement on peak bone mass and partnered with the American Society for Nutrition, which, in turn, charged a 9-member writing committee with using a systematic review approach to update the previous…

Two problems at two different abstraction levels of computational biology are studied. At the molecular level, efficient pattern matching algorithms in DNA sequences are presented. For gene order data, an efficient data structure is presented capable of storing all gene re-orderings in a systematic manner. A common characteristic of presented…

Colleges provide professional development opportunities to faculty to promote knowledge growth and improvement of skills. At the college, Scheduled Development (SD) time for faculty is based on the educational practice and recognition of the need for continuous professional development of faculty members. The paper presents a user-centered…

Addressing Sorensen and Tuma's resource-reward theory, we explored teacher attrition from an economic perspective. The study aimed to explore the extent to which teachers' resources and terms of employment correlate with attrition behavior. In a sample of 10,340 Israeli K-12 teachers it was found that many beginning teachers who left the…

In meta-analysis, the random-effects model is often used to account for heterogeneity. The model assumes that heterogeneity has an additive effect on the variance of effect sizes. An alternative model, which assumes multiplicative heterogeneity, has been little used in the medical statistics community, but is widely used by particle physicists. In…

Introduction: Previous studies suggest that many systematic reviews contain meta-analyses that display temporal trends, such as the first study's result being more extreme than later studies' or a drift in the pooled estimate. We assessed the extent and characteristics of temporal trends using all Cochrane intervention reports published 2008-2012.…
