ABSTRACT

A decontamination treatment using liquid CO₂ (li-CO₂) and specifically developed for the requirements of museum objects (Lombardo, T., M. Wörle, V. Hubert, E. Hildbrand, I. Mayer, C. Hinterleitner, U. von Arx. 2020. “Influence of Process Parameters on Chlorinated Biocide Decontamination by li-CO₂ on Artificially Contaminated Model Materials.” Studies in Conservation, in press, doi:10.1080/00393630.2019.1641001) was first tested on model materials of wood (with and without coating), silk, and wool with different dyes, paper, and leather in order to evaluate possible material changes. Then, selected museum objects from the collection of the Swiss National Museum were treated to determine the efficiency of biocide decontamination and any resulting chemical and/or structural changes. Results show that dichlorodiphenyltrichloroethane (DDT), pentachlorophenol (PCP), lindane, and chlorpyrifos were successfully removed. Wool, silk, leather, and non-coated wood did not experience any detectable modifications, while moderate to major modifications were observed in wood coated with shellac and polychromy.  相似文献   

Predicting women's college experiences from life history data: A four-year study     

Dr. Hubert S. Feild 《Research in higher education》1976,5(2):125-140

The present study was conducted over a four-year period to determine if life history or biographical information could be used to predict various college experiences of women. At the beginning of their freshman year, 897 women were administered a comprehensive life history questionnaire. During the last quarter of their senior year, 327 women (who received the life history questionnaire four years earlier) completed an inventory which assessed major dimensions of college experiences. Results indicated that life history data could be used to make longitudinal predictions of women's college experiences. The results were discussed in terms of their implications for counseling students in higher education.  相似文献

The 16 highest‐scored Roche vaults (G1) performed during the 2000 Olympic Games were compared with those receiving the 16 lowest‐scores (G2). A 16‐mm motion picture camera operating at 100 Hz recorded the vaults during the competition. The results of t tests (p < .05) indicated G1, compared to G2, had (a) shorter time of board support, greater normalised average upward vertical force and backward horizontal force exerted by the board, greater change in the vertical velocity while on the board, and greater vertical velocity at board take‐off, (b) comparable linear and angular motions in pre‐flight, (c) smaller backward horizontal impulse exerted by the horse, smaller loss of the horizontal velocity while on the horse, and greater horizontal and vertical velocities at horse take‐off, (d) greater height and larger horizontal distance of post‐flight, (e) higher body mass centre at knee release, and (f) higher mass centre, greater normalised moment of inertia, and smaller vertical velocity at mat touchdown. Therefore, gymnasts and coaches should focus on sprinting the approach; blocking and pushing‐off the take‐off board rapidly and vigorously; departing the board with a large vertical velocity; exerting large downward vertical force and small forward horizontal force from the handstand position while on the horse; departing the horse with large horizontal and vertical velocities; and completing the majority of the double salto forward near the peak of trajectory and releasing the knees above the top of the horse to prepare for a controlled landing.  相似文献   

Bubble entrainment, spray and splashing at hydraulic jumps     

CHANSON Hubert 《浙江大学学报(A卷英文版)》2006,7(8):1396-1405

INTRODUCTION A hydraulic jump is the sudden transition from a high-velocity, supercritical open channel flow into a slow-moving, sub-critical flow (Belanger, 1840; Bakhmeteff, 1932; Henderson, 1966; Chanson, 2004a). It is characterised by a sudden rise of the free-surface, with some strong energy dissipation and mixing, large-scale turbulence, air entrainment, waves and spray (Fig.1). Early experimental studies of air bubble entrainment were conducted in terms of the quantity of entrain…  相似文献   

Report of Committee on Criteria for Evaluation of Articles Submitted for Publication in the Research Quarterly April 1950

The aim of this study was to determine what visual information expert soccer players encode when they are asked to make a decision. We used a repetition-priming paradigm to test the hypothesis that experts encode a soccer pattern's structure independently of the players' physical characteristics (i.e., posture and morphology). The participants were given either realistic (digital photos) or abstract (three-dimensional schematic representations) soccer game patterns. The results showed that the experts benefited from priming effects regardless of how abstract the stimuli were. This suggests that an abstract representation of a realistic pattern (i.e., one that does not include visual information related to the players' physical characteristics) is sufficient to activate experts' specific knowledge during decision making. These results seem to show that expert soccer players encode and store abstract representations of visual patterns in memory.  相似文献   

Graduate Students’ Satisfaction with Graduate Education     

Hubert S. Feild  William H. Holley  Achilles A. Armenakis 《Journal of Experimental Education》2013,81(2):8-15

Various investigators have proposed that factors intrinsic to a particular situation, i.e., training, education, specific jobs, should have a significantly higher relationship with overall satisfaction than should factors extrinsic to that situation (4, 10). This study was designed to investigate the effects of intrinsic and extrinsic factors on graduate students’ satisfaction with their graduate education. To achieve this purpose, an instrument, the Graduate Education Questionnaire (GEQ), was administered to sixty-two graduate students in business at a large, southeastern university. Essentially, they were asked to rate their degree of satisfaction with a series of variables suggested as being important to their graduate education. Contrary to expectations, the results of this study indicated that a set of variables intrinsic to graduate students’ education did not predict overall satisfaction significantly better than a set of extrinsic variables. Similar results have also been confirmed in other contexts as well (5). From the data collected, implications of the results are discussed.  相似文献

Processing of anaphoric devices in young skilled and less skilled comprehenders: Differences in metacognitive monitoring     

Ehrlich  Marie-France  Remond  Martine  Tardieu  Hubert 《Reading and writing》1999,11(1):29-63

This experiment investigated metacognitive monitoring in the processing of anaphors in 10–year-old skilled and less skilled comprehenders. Two tasks were used with expository texts. The direct self-evaluation task was carried out with consistent texts in which target anaphors were either repeated noun phrases or pronouns. Subjects had to read and to evaluate their own comprehension on a 6–point scale. After reading, subjects answered multiple-choice questions designed to test the processing of anaphors. In the inconsistency detection task, target anaphors were either repeated noun phrases or inconsistent noun phrases. Subjects had to read and detect inconsistencies. After reading, they answered multiple-choice questions. In both tasks, on-line measures (reading times for units containing target anaphors and for subsequent units, and look-backs) were collected in addition to off-line measures (ratings of comprehension, detection of inconsistencies and response to multiple-choice questions) in order to analyse indicators of implicit and explicit evaluation and revision activities. The results from the two tasks converged: less skilled comprehenders showed deficiencies in monitoring on measures of implicit and explicit evaluation and revision. Patterns of reading times revealed that less skilled comprehenders were sensitive to the difficulties in processing pronouns in the self-evaluation task and also sensitive to the lack of text cohesion in the inconsistency detection task. However, this sensitivity was weak and unable to trigger explicit activities. These results were interpreted in the framework of Karmiloff-Smith's (1986) model.  相似文献   

A longitudinal comparison of WISC-III and WISC-R scores of special education students     

Hubert Vance  Cleborne D. Maddux  Gerald B. Fuller  Abeer M. Awadh 《Psychology in the schools》1996,33(2):113-118

This study investigated the performance of 166 special education students who had been administered the WISC-R and approximately 3 years later the WISC-III. The sample ranged in age from 6.0 to 16.6 years. The scores were analyzed using Pearson product moment correlation coefficients and t tests of the differences between means for related samples. The results indicated that there was a significant, positive correlation among global scales (p < .001). This finding suggests that the WISC-R and the WISC-III IQ scores measure similar abilities. Analysis of mean IQ score differences revealed significant differences in the WISC-R and the WISC-III IQ scores, with the WISC-III global scores being lower. Implications for the evaluation of students for special education are discussed, with special emphasis on the role and function of the psychologist practicing in the schools. © 1996 John Wiley & Sons, Inc.  相似文献
