“…In addition, a standardization approach for each indicator is used based on the distribution of data within a particular indicator-a cumulative probability function using a version of Z-scoring (see [57] (pp. [91][92][93] and [58]). Within the applied dataset from THE, not all out of the five indicator values reached a maximum of 100 among the selected 70 European universities, as in some cases the 100 maximum value was attained by a non-European university (Australia, Canada, China, the United States, etc.…”

The Index Number Problem with DEA: Insights from European University Efficiency Data

An increasing effort has been put into dealing with the question of time-series analysis regarding institutional efficiency, including in the area of higher education. Universities are important institutions for economies and societies and are expected to provide excellence as well as efficiency in their processes and outputs. This is reflected in the context of an increased global competitive environment by more refined international university rankings. Combining the two areas, this paper points towards a methodological challenge in comparing different ranking datasets for their use in a data envelopment analysis (DEA) Malmquist index time-series efficiency analysis, namely, index-based data compared to additive data. The problem is discussed in a theoretical framework and complemented with an empirical application: calculations for 70 European universities with budget and staff input data and different ranking output data for the timeframe of 2011-2016 show that there is no evidence for a specific index data problem. Important implications regarding university management and higher education policies are outlined. Efficiency improvements among the analyzed universities are significant but also unevenly distributed and not easy to obtain for individual institutions.

“…This is similar to web survey designs which give respondents full navigation control (often using a navigation pane on the left of the screen), while still providing a default path through the instrument and minimizing mouse clicks. On smartphones, the answering pane on the right is displayed, and respondents can only see the navigation pane by using the smartphone in landscape mode (for more details of the ZEF interface, see Selkälä, Ronkainen, & Alasaarela, 2011).…”

Several authors and software vendors advocate the benefits of auto forwarding in web surveys, but there is little empirical research on this approach. We experimentally tested automatic versus manual forwarding (MF) under different levels of cognitive effort. We manipulated information accessibility (IA; low vs. high) and consistency requirements (CRs; yes vs. no), along with auto forwarding (AF) versus MF in two studies conducted among students in Finland. We find that an AF survey takes less time to complete, but only for those completing a survey on personal computers or tablets; no time advantage is found for smartphone users. We also find that respondents in both AF and MF conditions return more often to items with higher cognitive burden (low IA or a CR). MF respondents change answers more often than AF respondents. AF appears to reduce straightlining slightly. We find no difference in response consistency between two behavioral items between AF and MF, but a slight advantage for AF for two attitude items. Finally, respondents reported more positive experiences with the AF version. Auto forwarding appears to be somewhat more efficient and easy to use but may decrease the quality of responses to cognitively demanding questions.

The increased availability of online collaboration tools enables participants in different locations to create knowledge and work together. This paper shares the results of a project in which first-year introductory technology students from Bentley University in the United States and fourth-year multimedia students from Politehnica University of Timisoara in Romania worked together in an online global educational environment to research technology trends and create multimedia artifacts that shared their findings.
