04091 Abstracts Collection -- Data Structures

From 22.02. to 27.02.2004, Dagstuhl Seminar "Data Structures" was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar are put together in this paper. The first section describes the seminar topics and goals in general

Scientism as illusio in HR algorithms: Towards a framework for algorithmic hygiene for bias proofing

© 2022 The Authors. Human Resource (HR) algorithms are now widely used for decision making in the field of HR. In this paper, we examine how biases may become entrenched in HR algorithms, which are often designed without consultation with HR specialists, assumed to operate with scientific objectivity and often viewed as instruments beyond scrutiny. Using three orienting concepts such as scientism, illusio and rationales, we demonstrate why and how biases of HR algorithms go unchecked and in turn may perpetuate the biases in HR systems and consequent HR decisions. Based on a narrative review, we examine bias in HR algorithms; provide a methodology for algorithmic hygiene for HR professionals

Factors Affecting Use of E-mail by Public School Principals of the Central Appalachian Region

The purposes of this study were to determine the factors that influence the use of e-mail by principals, the purposes for which e-mail messages were sent and received, and the impact of experience and training in the areas of computers and e-mail. A survey was sent to a stratified random sample of 620 elementary, middle/junior high, and high school principals of the Central Appalachian Region. Respondents were asked to provide data regarding demographics, accessibility to hardware and software, computer and e-mail experience and training, uses of e-mail, and items that influence e-mail use. Eleven research questions and 10 hypotheses were addressed. Data analysis included descriptive statistics, chi-square, ANOVA, multiple regression, and factor analysis. At the.05 level of significance eight null hypotheses were retained and two rejected. Factor analysis identified four factors for e-mail users and five factors for non-users. E-mail was used by 59.7% of respondents. There was no relationship between level of use and gender, age, highest degree earned, or total years of educational experience. The predictors of e-mail use were computer experience, accessibility to resources, and training. Keyboarding skills and use of e-mail by superiors, fellow principals, and teachers were not indicators of e-mail use. Principals primarily use e-mail for administrative tasks and secondarily for accessing and retrieving information. Training is essential to the effective implementation and use of e-mail. There were six primary training methods for computers and e-mail. Factor analysis revealed that e-mail users have hardware and software resources, training, support, and encouragement to use e-mail to obtain educationally beneficial and appropriate information. Non-users were not comfortable with the technology. Principals must be cognizant of e-mail\u27s capabilities and potential ramifications upon the educational community and provide the role model for the use of technology. E-mail has the potential to break down barriers of geographical isolation and instill a sense of community. If future educational leaders are to be prepared to meet the challenges of an information age, colleges of education need to provide instruction in the use of computers and e-mail

Cross-shore and longshore sediment size distribution on southern Currituck Spit, North Carolina

Using Q-mode factor analysis, 87 surficial sediment samples collected from Duck and Whalehead beach, North Carolina, were analyzed using the weight percent of the gravel and sand fraction subdivided at 0.5 phi class interval as variables. An additional data set composed of 178 surficial sediment samples from Duck beach (bimodal) and Coquina beach (unimodal fine) representing three years of sampling at monthly intervals were analyzed by the same technique using only the sand fraction. The spatial and temporal patterns of sediment factor groups support three main inferences. (1) Bimodal beaches display a more distinct sediment zonation than unimodal beaches. (2) On a long term basis (yearly), cross-shore grain-size distributions represent depositional processes. Particularly on bimodal beaches, the association of sediment factor groups with specific zones of the beach profile delineates a textural differentiation produced by the type and amount of energy inherent in each zone. Combinations of Q-mode factor analysis and other environmental sensitive techniques (e.g. log-probability plots of grain-size distributions) proved to be useful for interpreting sedimentary processes at the depositional site. (3) The cross-shore patterns which represent an average of the sedimentary processes occurring under fair weather and storm conditions indicate that coarse sediments are concentrated on the backshore. In contrast, fine sediments are located landward or shoreward of this zone where they are exposed to energy conditions that result in their depletion in the subaerial beach. Using the Q-mode factor model, 350 new sediment samples from beaches located between Duck and Oregon Inlet were mapped in the factor space defined by the Duck-Coquina data set. The along-coast results support the cross-shore trends observed in the previous studies and indicates that there are several sources of coarse sediments between Duck and Oregon Inlet. Sedimentologic, stratigraphic and seismic data offshore and landward of the barrier substantiate these findings and demonstrate that differences in subaerial beach morphology in this part of Currituck Spit, is primarily due to the availability of coarse sediments from the paleodrainage of the Albemarle river
