Over the past decade, text recycling (TR; AKA ‘self‐plagiarism’) has become a visible and somewhat contentious practice, particularly in the realm of journal articles. While growing numbers of publishers are writing editorials and formulating guidelines on TR, little is known about how editors view the practice or how they respond to it. We present results from an interview‐based study of 21 North American journal editors from a broad range of academic disciplines. Our findings show that editors' beliefs and practices are quite individualized rather than being tied to disciplinary or other structural parameters. While none of our participants supported the use of large amounts of recycled material from one journal article to another, some editors were staunchly against any use of recycled material, while others were accepting of the practice in certain circumstances. Issues of originality, the challenges of rewriting text, the varied circulation of texts, and abiding by copyright law were prominent themes as editors discussed their approaches to TR. Overall, the interviews showed that many editors have not thought systematically about the practice of TR, and they sometimes have trouble aligning their beliefs and practices. 相似文献

Sweat lactate reflects eccrine gland metabolism. However, the metabolic tendencies of eccrine glands in a hot versus thermoneutral environment are not well understood. Sixteen male volunteers completed a maximal cycling trial and two 60-min cycling trials [30°C?=?30±1°C and 18°C?=?18±1°C wet bulb globe temperature (WBGT)]. The participants were requested to maintain a cadence of 60 rev?·?min?1 with the intensity individualized at ～ 90% of the ventilatory threshold. Sweat samples at 10, 20, 30, 40, 50 and 60?min were analysed for lactate concentration. Sweat rate at 30°C (1380±325?ml?·?h?1) was significantly greater (P<0.05) than at 18°C (632±311?ml?·?h?1). Sweat lactate concentration was significantly greater (P<0.05) at each time point during the 18°C trial, with values between trials tending to converge across time. During the 30°C trial, both heart rate (20, 30, 40, 50 and 60?min) and rectal temperature (30, 40, 50 and 60?min) were significantly higher than in the 18°C trial. Higher sweat lactate concentrations coupled with lower sweat rates may indicate a greater relative contribution of oxygen-independent metabolism within eccrine glands during exercise at 18°C. Decreases in sweat lactate concentration across time suggest either greater dilution due to greater sweat volume or increased reliance on aerobic metabolism within eccrine glands. The convergence of lactate concentrations between trials may indicate that time-dependent modifications in sweat gland metabolism occur at different rates contingent partially on environmental conditions. 相似文献

The shift from a centralized to a decentralized school system can be seen as a solution to an uncertain problem. Through analysing the displacements in the concept of equivalence within Sweden’s decentralized school system, this study illustrates how the meaning of the concept of equivalence shifts over time, from a more collective target achievement for the educational system as a whole to a more individually interpreted goal‐fulfilment. 相似文献

To examine the reproducibility of three measurement techniques used to determine creatine kinase, interleukin-6 and high-sensitivity C-reactive protein, 50 participants had blood samples taken on two occasions. Fingertip plasma samples were analysed using the Reflotron for CK determination. Venous blood samples collected into serum separator tubes were used for IL-6 and hs-CRP analyses. IL-6 was measured using an enzyme linked immune assay development kit. The hs-CRP was measured by an in-house ELISA method. Dependent t-tests showed no systematic bias between samples. The interdian CV was 20.0% for CK, 15.3% for IL-6 and 44.2% for hs-CRP. The intraclass correlation coefficient was 0.90 for CK, 0.98 for IL-6 and 0.70 for hs-CRP. The 95% limits of agreement were ?69.7 to 63.5 IU/L for CK, ?1.48 to 1.80 pg/ml for IL-6 and ?1.10 to 0.91 µg/L for hs-CRP. The results demonstrate low absolute reproducibility, which may obscure a true experimental effect. 相似文献
