Federal open records laws, executive orders on national security classification, and similar policy instruments in the states require that most records at government agencies be available to the public upon request—subject to exemptions which may entail review. Traditionally, this review has been accomplished by redaction (purging) of hardcopy. Resource limitations and increases in the number of requests demand a rethinking of the process. Offices are experimenting with optical scanning, onscreen purging, and online dissemination. Statutory and common law trends may soon require disclosure of database reports in electronic form, when so requested, rather than printouts. The dissemination of manipulable data of commercial value requires a rationale broader than the “citizenship rights” that justified the Freedom of Information Act. Online publication of agency-controlled records also demands careful planning of information systems and public networks. The issues discussed in this article are central to the establishment of an adequate policy for electronic freedom of information. 相似文献

The purpose of this study was to determine if a difference in interleukin-6 (IL-6) and delayed onset muscles soreness (DOMS) exists in two different phases of the menstrual cycle. Nine runners performed one 75-min high-intensity interval running session during the early follicular (EF) phase and once during the midluteal (ML) phase of the menstrual cycle. Estrogen and progesterone levels were significantly reduced in the EF phase when compared to the ML phase. IL-6 levels increased from pre- to postexercise in the EF and ML phases (p < .001). There was no relationship between the IL-6 level and DOMS. The results suggest that menstruating female runners need not vary training throughout the month to reduce DOMS. 相似文献

The aim was to compare exercise with and without different degrees of blood-flow restriction on perceived exertion (RPE) and discomfort. Participants were assigned to Experiment 1, 2, or 3. Each completed protocols differing by pressure, load, and/or volume. RPE and discomfort were taken before and after each set. For pressure and RPE, the 20% one repetition maximum (1RM) blood-flow restriction conditions were affected by increasing the pressure from 40% to 50% blood-flow restriction (~12 vs. ~14). This did not appear to happen within the 30% 1RM blood-flow restriction conditions or the higher pressures in the 20% 1RM conditions. The similar RPE between 20% and 30% 1RM to failure was expected given both were to failure. For discomfort, ratings were primarily affected by load at the lowest pressure. Increasing pressure to 50% blood-flow restriction increased discomfort at 20% 1RM (~2.6 vs. ~4). There was a further increase when increasing to 60% blood-flow restriction (~4 vs. ~4.8). The high-load condition had the lowest discomfort, while ratings were highest with 20% 1RM to failure. In conclusion, exercise with blood-flow restriction does not appear to augment the perceptual response observed with low-load exercise to failure. 相似文献

The paper proposes and describes a framework for academic library quality to be used by new and more experienced library practitioners and by others involved in considering the quality of academic libraries' services and provision. The framework consists of eight themes and a number of questions to examine within each theme. The framework was derived from a detailed content analysis of two major sources of information: the content of a recent book on quality and academic libraries edited by the author; the content of the journal articles, books and conference proceedings identified for the various literature reviews included in the book. To illustrate the development of the framework, some of the main activities, processes, and issues defined within each theme are described, and extensive references from the literature are included. 相似文献

The educational psychologist can be a very important resource to a school. The psychologist’s knowledge of the school and its context is key. Through regular consultation with schools, educational psychology services can provide help in clarifying problems and devising problem solving strategies; in carrying out specialised assessments, including techniques in managing behaviour and evaluating pupil progress.

Cognitive interviewing (CI) provides a method of systematically collecting validity evidence of response processes for questionnaire items. CI involves a range of techniques for prompting individuals to verbalise their responses to items. One such technique is concurrent verbalisation, as developed in Think Aloud Protocol (TAP). This article investigates the value of the technique for validating questionnaire items administered to young people in international surveys. To date, the literature on TAP has focused on allaying concerns about reactivity – whether response processes are affected by thinking aloud. This article investigates another concern, namely the completeness of concurrent verbalisations – the extent to which respondents verbalise their response processes. An independent, exploratory validation of the PISA assessment of student self-efficacy in mathematics by a small international team of researchers using CI with concurrent verbalisation in four education systems (England, Estonia, Hong Kong, and the Netherlands) provided the basis for this investigation. The researchers found that students generally thought aloud in response to each of the items, thereby providing validity evidence of responses processes varying within and between the education systems, but that practical steps could be taken to increase the completeness of concurrent verbalisations in future validations. 相似文献
