This paper presents findings from the first year of school-based case studies investigating the ‘Impact of School Leadership on Pupil Outcomes’. The case study component of this study involved twenty schools (ten primary and ten secondary), all of which were selected on the basis of their sustained improvement (over at least three consecutive years) in terms of pupil outcomes. Interviews were c...

The ability to monitor assistance, define humanitarian needs, and approach equity in the distribution of assistance has lagged behind the world's growing commitment to responding to humanitarian emergencies. This article highlights relevant data sources to elucidate elements of an operational definition of humanitarian need. New and refined measures are proposed to assist in assessing the level...

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instruction, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including s...

In one large survey project each record in the raw data set contains information from one survey form. At some point, Adenormalization@ of the data needs to be done transposing a multiple-record-per-object data set to a one-record-perobject data set that retains all raw variables from all data sources. The large dimension of the original data set requires an approach that can: a) carry out the ...

Mendelian randomization analyses are often performed using summarized data. The causal estimate from a one-sample analysis (in which data are taken from a single data source) with weak instrumental variables is biased in the direction of the observational association between the risk factor and outcome, whereas the estimate from a two-sample analysis (in which data on the risk factor and outcom...

While it is common practice for health surveys to include an open-ended question asking for additional comments, the responses to these questions are often not analysed or used by researchers as data. The current project employed an automated semantic program to assess the useability and thematic content of the responses to an open-ended free response item included in the Australian Longitudina...

Crises in financial markets affect humans worldwide. Detailed market data on trading decisions reflect some of the complex human behavior that has led to these crises. We suggest that massive new data sources resulting from human interaction with the Internet may offer a new perspective on the behavior of market participants in periods of large market movements. By analyzing changes in Google q...
