Nebraska Policy Choices: 1988

The six chapters in Nebraska Policy Choices: 1988 contain the work of eight faculty from the University of Nebraska\u27s Omaha and Lincoln campuses. These faculty, like the twenty-five faculty who wrote chapters for the previous two annual volumes, are some of the leading experts in Nebraska in their respective areas of interest

Nebraska Policy Choices: 1987

Nebraska Policy Choices: 1987 represents the work of 14 faculty from the University of Nebraska\u27s Omaha and Lincoln campuses. As last year, the authors are some of the leading experts in the state in their respective areas of interest. The depth of faculty capacity, coupled with the breadth and timeliness of the topics, combine to make Nebraska Policy Choices: 1987 an exciting publication

mSpace Mobile: Exploring Support for Mobile Tasks

In the following paper we compare two Web application interfaces, mSpace Mobile and Google Local in supporting location discovery tasks on mobile devices while stationary and while on the move. While mSpace Mobile performed well in both stationary and mobile conditions, performance in Google Local dropped significantly. We postulate that mSpace Mobile performed so well because it breaks the paradigm of the page for delivering Web content, thereby enabling new and more powerful interfaces to be used to support mobility

mSpace: improving information access to multimedia domains with multimodal exploratory search

Overview of mSpace interaction approach for presenting exploratory search particularly in the audio domain by using slices, preview cues, and user-determined organization of information from high-dimensional space

mSpace Mobile: a UI Gestalt to Support On-the-Go Info-Interaction

mSpace Mobile Interaction presents a UI gestalt of 7 techniques for mobile/on-the-move information retrieval and assessment that enables multiple views of the information within a persistent focus+context viewer. It uses the web but breaks the web page paradigm to support effective rapid triage

Line Emission in the Brightest Cluster Galaxies of the NOAO Fundamental Plane and Sloan Digital Sky Surveys

We examine the optical emission line properties of Brightest Cluster Galaxies (BCGs) selected from two large, homogeneous datasets. The first is the X-ray selected National Optical Astronomy Observatory Fundamental Plane Survey (NFPS), and the second is the C4 catalogue of optically selected clusters built from the Sloan Digital Sky Survey Data Release ~3 (SDSS DR3). Our goal is to better understand the optical line emission in BCGs with respect to properties of the galaxy and the host cluster. Throughout the analysis we compare the line emission of the BCGs to that of a control sample made of the other bright galaxies near the cluster centre. Overall, both the NFPS and SDSS show a modest fraction of BCGs with emission lines (~15%). No trend in the fraction of emitting BCGs as a function of galaxy mass or cluster velocity dispersion is found. However we find that, for those BCGs found in cooling flow clusters, 71^{+9}_{-14}% have optical emission. Furthermore, if we consider only BCGs within 50kpc of the X-ray centre of a cooling flow cluster, the emission-line fraction rises further to 100^{+0}_{-15}%. Excluding the cooling flow clusters, only ~10% of BCGs are line emitting, comparable to the control sample of galaxies. We show that the physical origin of the emission line activity varies: in some cases it has LINER-like line ratios, whereas in others it is a composite of star-formation and LINER-like activity. We conclude that the presence of emission lines in BCGs is directly related to the cooling of X-ray gas at the cluster centre.Comment: Accepted for publication in MNRAS. 13 pages mn2e style with 7 figures and 2 table

Continuum: designing timelines for hierarchies, relationships and scale

Temporal events, while often discrete, also have interesting relationships within and across times: larger events are often collections of smaller more discrete events (battles within wars; artists' works within a form); events at one point also have correlations with events at other points (a play written in one period is related to its performance, or lack of performance, over a period of time). Most temporal visualisations, however, only represent discrete data points or single data types along a single timeline: this event started here and ended there; this work was published at this time; this tag was popular for this period. In order to represent richer, faceted attributes of temporal events, we present Continuum. Continuum enables hierarchical relationships in temporal data to be represented and explored; it enables relationships between events across periods to be expressed, and in particular it enables user-determined control over the level of detail of any facet of interest so that the person using the system can determine a focus point, no matter the level of zoom over the temporal space. We present the factors motivating our approach, our evaluation and implementation of this new visualisation which makes it easy for anyone to apply this interface to rich, large-scale datasets with temporal data

Management and Labor Appraisals and Criticisms of the Arbitration Process: A Report with Comments

Although arbitration as a means of resolving disputes arising under collective bargaining agreements has received widespread acceptance in this country/ in recent years there has been some evidence of increasing criticism of the process. As part of a research project dealing with the impact of the 1960 Supreme Court decisions in the Warrior & Gulf trilogy and the 1962 Sinclair trilogy, we decided to ascertain how parties are appraising the arbitration process. We report here the more significant results of this survey along with our evaluation of the criticisms and suggestions which were received

Nebraska Settlements: Status, Trends, and Policy Choices

This chapter looks at historical and contemporary trends in Nebraska\u27s system of incorporated places. Particular attention is given to changes in the number and proportion of places in different population size categories, the movement of places between different size categories, and what Nebraska\u27s settlement system is likely to look like in the future. A review of past and recent trends, together with forecasts about the future, indicates a likely increase in the number of very small places, major shifts for middle-sized places, and continued growth in the number of places over 5,000 population. Based upon these trends, three separate needs tied to each community type are identified. These include managing decline, strategic economic planning assistance, and growth center promotion. The chapter concludes with a discussion of criteria that might guide choices about which categories of places in Nebraska to assist and how to provide help to those places identified for assistance

Community Development Needs in Nebraska: Attitude Survey Results and Local Action Strategies

Each S.T.A.R.T. Economic Development community administers a community attitude survey to local residents. Generally the survey serves at least two purposes. One is to collect information about the attitudes and behavior of local. residents. For example, respondents are asked to rate a variety· of community services, programs and organizations. The questionnaire also collects information about shopping behavior and local preferences about economic development
