AbstractTo determine the state of the cataloging job market, this study compares job advertisements from August 2016-August 2018 advertising for jobs with cataloging in the title, metadata in the title, and cataloging and metadata in the title. Given ongoing concerns about the impact of metadata jobs on the cataloging job market, this study asks the questions: Are cataloging jobs in fact “disappearing” and becoming metadata jobs? Are entry-level jobs disappearing, perhaps contributing to the idea that there is a lack of qualified catalogers? Is there a difference in position level between cataloging and metadata job advertisements that can account for a lack or perceived lack of available cataloging jobs? Are there more entry-level or mid/supervisory positions advertised? Are cataloging and metadata jobs really separate, or should they be considered one position called cataloging and metadata? 相似文献

ABSTRACT The aims of the present study were to provide an in-depth comparison of inter-limb asymmetry and determine how consistently asymmetry favours the same limb during different vertical jump tests. Eighteen elite female under-17 soccer players conducted unilateral squat jumps (SJ), countermovement jumps (CMJ) and drop jumps (DJ) on a portable force platform, with jump height, peak force, concentric impulse and peak power as common metrics across tests. For the magnitude of asymmetry, concentric impulse was significantly greater during the SJ test compared to CMJ (p = 0.019) and DJ (p = 0.003). No other significant differences in magnitude were present. For the direction of asymmetry, Kappa coefficients revealed fair to substantial levels of agreement between the SJ and CMJ (Kappa = 0.35 to 0.61) tests, but only slight to fair levels of agreement between the SJ and DJ (Kappa = ?0.26 to 0.18) and CMJ and DJ (Kappa = ?0.13 to 0.26) tests. These results highlight that the mean asymmetry value may be a poor indicator of true variability of between-limb differences in healthy athletes. The direction of asymmetry may provide a useful monitoring tool for practitioners in healthy athletes, when no obvious between-limb deficit exists. 相似文献

The aim of this paper is to present a reliability modeling and analysis of a two-unit system of a continuous casting (CC) plant. Real maintenance data of a steel production plant have been used for the purpose. Three types of failures were noted: repairable, replaceable and reconditioning/reinstallation. The two-unit system is operating in parallel, on full-reduced installed capacity. Upon the unit failure, an inspection is carried out to decide the type of maintenance task to be performed. Optimized reliability indices of the plant such as mean time to system failure, availability, expected busy periods of the repairman for various maintenance tasks, expected number of visits by the repairman, expected number of repairs, replacements and reconditioning/reinstallation are obtained. Semi-Markov processes and regenerative point techniques are used for the analysis. Profit incurred to the CC plant is also evaluated and related graphs are plotted to demonstrate the results. 相似文献

Abstract Although transition outcomes for youth with disabilities have shown some improvement and transition support practices have been identified, many young people continue to face transition barriers that preclude their full participation in key adult life activities. While research efforts have largely been professionally driven, there is emerging literature suggesting that the use of participatory, empowerment methodologies may bolster the identification of appropriate research methods and useful solutions to problems, as well as promoting the application of findings to accomplishing practice and policy improvements. The purpose of this study was to use a youth-directed, participatory action methodology to investigate youths' perceptions of the value of transition promotion experiences identified as effective by professionals, and to examine the level at which youth with disabilities participate in those experiences. A survey was developed and administered to 202 young people with disabilities by leaders from the National Youth Leadership Network. Findings indicated that youth generally endorse the importance of validated transition promotion practices; however, they reported having limited opportunity to participate in them. Implications related to the use of participatory action methodologies and needed practice and policy improvements are discussed. 相似文献

Charles Perrow used the term “normal accidents” to characterize a type of catastrophic failure that resulted when complex,
tightly coupled production systems encountered a certain kind of anomalous event. These were events in which systems failures
interacted with one another in a way that could not be anticipated, and could not be easily understood and corrected. Systems
of the production of expert knowledge are increasingly becoming tightly coupled. Unlike classical science, which operated
with a long time horizon, many current forms of expert knowledge are directed at immediate solutions to complex problems.
These are prone to breakdowns like the kind discussed by Perrow. The example of the Homestake mine experiment shows that even
in modern physics complex systems can produce knowledge failures that last for decades. The concept of knowledge risk is introduced,
and used to characterize the risk of failure in such systems of knowledge production. 相似文献

This study examined the ability of children in French immersion and English programs to analyze the internal structure of spoken words in relation to their early reading and spelling abilities in English. Thirty-two children in the first grade were given a modified version of the Auditory Analysis Test, and reading and spelling tasks that included both real words and non-words. Results indicated that French immersion children were more proficient than their English program peers at explicitly analyzing spoken words and that the groups did not differ when reading and spelling orthographically regular real words and non-words. The English program children performed better than their French program peers only when reading orthographically irregular English words. These results demonstrate that second language learning enhances metalinguistic awareness and help to explain why children in immersion programs do not experience long-term difficulty in acquiring English written language skills. 相似文献
