The problem of building test collections is central to the development of information retrieval systems such as search engines. The primary use of test collections is the evaluation of IR systems. The widely employed "Cranfield paradigm" dictates that the information relevant to a topic be encoded at the level of documents, therefore…

Systematic, practical, and accessible, this is the first book to focus on finding the most defensible design for a particular research question. Thoughtful guidelines are provided for weighing the advantages and disadvantages of various methods, including qualitative, quantitative, and mixed methods designs. The book can be read sequentially or…

In my dissertation, I will present my research which contributes to solve the following three open problems from biomedical informatics: (1) Multi-task approaches for microarray classification; (2) Multi-label classification of gene and protein prediction from multi-source biological data; (3) Spatial scan for movement data. In microarray…

Based on a review of the existing literature on database design, this study proposed a unified database model to support corporate technology innovation. This study assessed potential support for the model based on the opinions of 200 technology industry executives, including Chief Information Officers, Chief Knowledge Officers and Chief Learning…

This paper reviews the Integrated Postsecondary Education Data System (IPEDS) "system" definition to determine if it accurately reflects the general understanding of a "system" in the higher education community. In addition, this paper examines systems that have been reported to IPEDS to determine if each fits the definition.…

Calculus instructors struggle to teach infinite series, and students have difficulty understanding series and related concepts. Four instructional strategies, prominently used during the calculus reform movement, were implemented during a 3-week unit on infinite series in one class of second-semester calculus students. A description of each…

Purpose: The purpose of this article is to evaluate a method for measuring work activities and skill requirements of 160 occupations in eight countries, used in EurOccupations, an EU-FP6 project. Additionally, it aims to explore how the internet can be used for measuring work activities and skill requirements. Design/methodology/approach: For the…

When times get tough, grown children often turn to their parents for help--for some extra cash, even somewhere to stay. For colleges and universities, that role is filled by alumni donors. In 2011, with education budgets slashed across the country, giving accounted for 6.5 percent of college expenditures, according to the Council for Aid to…

Interval recording procedures are used by persons who collect data through observation to estimate the cumulative occurrence and nonoccurrence of behavior/events. Although interval recording procedures can increase the efficiency of observational data collection, they can also induce error from the observer. In the present study, 50 observers were…

Maternal, Infant, and Early Childhood Home Visiting legislation permits states to fund "promising practices"--with the understanding that these models will have a rigorous evaluation component. This article describes an innovative, low cost paraprofessional home visiting model developed in Pennsylvania by the Maternity Care Coalition. In…

Statistical literacy is essential in everyone's personal lives as consumers, citizens, and professionals. To make informed life and professional decisions, students are required to read, understand, and interpret vast amounts of information, much of which is quantitative. To develop statistical literacy so students are able to make sense of…

The "Next-Generation Science Standards" emphasize the importance of teaching the practices of science alongside content ideas and crosscutting concepts (NGSS Lead States 2013). Chief among these practices is the ability to gather, assess, analyze, and interpret data. Authentic inquiry near the leading-edge of science offers a wonderful…

While some students are enjoying days at the park or at the beach, forty middle school students are in a classroom solving challenging mathematics problems. The second Math Camp for middle school students was offered in 2013 at a western university for students from local school districts. For three days, these students met from 10 a.m. to 3 p.m.…

The ability of pre-service teachers (PSTs) to transfer learning between subjects and contexts when problem solving is critical for developing their capability as technologists and teachers of technology. However, a growing body of literature suggests this ability is often assumed or over-estimated, and rarely developed explicitly within courses or…

Purpose: The study investigates the ways in which principals engage with, and attend to, the data-driven accountability measures of No Child Left Behind (NCLB) and local mandates. Theoretical framework: The study is framed with the notion of "assemblage", a term often associated with actor-network theory (ANT)--a theory that focuses…
