SCI期刊影响因子膨胀加剧及其对科研评价的影响     

焦阳  宋轶文  程琴娟  李博  李雨桐 《编辑学报》2023,(4):355-361

使用2015—2022年Clarivate Analytics发布的期刊引证报告(JCR)数据进行统计分析,探究近年来SCI期刊的影响因子(JIF)变化特征及其对科研评价的影响。研究发现,2015—2022年期间高JIF的SCI期刊比例增加,低JIF的SCI期刊比例下降,JIF整体出现连年上涨趋势,且2021、2022年涨幅显著增加。这说明SCI期刊的JIF正在经历泡沫式膨胀且情况日益加剧,而中国SCI期刊的JIF增长率更甚于世界平均水平。JIF膨胀表面是论文数量和参考文献列表长度扩张的产物,但受益期刊精英群体和受益作者群体的推崇才是其增长的内在驱动,其侧面反映了追求高JIF的学术风气依然高涨,将造成JIF指标的进一步强化和滥用,引发更多有关结构性歧视和学术公平性的矛盾。此外,JIF前50位期刊多数保持稳定,其中知名期刊家族占有举足轻重的地位;而中国SCI期刊数量仅占世界总量的1.45%,在2022年JIF前50位期刊中只有1家,国际影响力较小。培育国内高影响力期刊,完善学术期刊评价体系,进行期刊质量、效益、贡献多维评价,并结合同行评议开展科研综合评价,是破“SCI至上”、弱化JIF膨...  相似文献   

古村落型文化遗产旅游地历史保护体系、原则与策略   总被引：1，自引：0，他引：1  

陈麦池  黄成林 《华侨大学学报(哲学社会科学版)》2011,(2):43-51

历史保护除要求对古迹遗址、历史建筑、传统民居及街巷和历史文化见证物等进行修缮外,更倡导对文化遗产地的经济、社会和文化结构中各种积极因素的保护和利用。目前,国内旅游业界和学界始终侧重于旅游业发展中的经济作用,其社会及文化影响尚未引起足够的重视。特别是古村落型文化遗产旅游地更是面临着亟待解决的诸多困境,因此,有必要借鉴并整合地理学、建筑学、城市规划学、民俗学和民族学对历史街区、非物质文化遗产和民族文化等问题的理论、方法与实践,构建多学科多层次的古村落型文化遗产旅游地历史保护体系,遵循遗产物质及环境整体性、文化原真性和社区参与及社会重建等原则,并采用创新及完善保护机制,实施历史文化保护区及博物馆化,试验文化及社会传统复兴等策略。  相似文献   

Systematic Dynamic Effects in Multiple Impact Pairs and Distributed Factors     

V.L.Krupenin 《出版与印刷》2015,(1)

In this paper in general the dynamic effects are considered and described, caused by different stand-ing waves in discrete and distributed systems with impacts and other strongly positional non-linear fac-tors, introduction of which in the models of me-chanical objects is dictated by the necessity to con-sider processes, accompanied with impacts of me-chanical subsystems of different nature.  相似文献

The Development of Sport in Museums     

J. Reilly 《国际体育史杂志》2015,32(15):1778-1783

Sport as a topic for museum collection, display, and interpretation has gradually developed over the last 100 years. However, until recently, there has been very little discussion or examination of the material culture of sport within the literature. Consequently, there is a misconception that sport in museums is relatively new, little is understood about the role and value of sporting heritage, and sporting collections are rarely used to inform historical study. In turn, the museum sector would benefit from more opportunities to work with sports historians whilst developing and delivering their sporting provision. Therefore, this paper examines the development of sport in museums, explores the current activity being developed in the field including the work of the Sport in Museums Network and the National Sporting Heritage Day, and offers practical information about how partnerships between academics and museum practitioners can be established to create a better understanding of the history and heritage of sport.  相似文献   

Validation of two accelerometers to determine mechanical loading of physical activities in children

The purpose of this study was to assess the validity of accelerometers using force plates (i.e., ground reaction force (GRF)) during the performance of different tasks of daily physical activity in children. Thirteen children (10.1 (range 5.4–15.7) years, 3 girls) wore two accelerometers (ActiGraph GT3X+ (ACT), GENEA (GEN)) at the hip that provide raw acceleration signals at 100 Hz. Participants completed different tasks (walking, jogging, running, landings from boxes of different height, rope skipping, dancing) on a force plate. GRF was collected for one step per trial (10 trials) for ambulatory movements and for all landings (10 trials), rope skips and dance procedures. Accelerometer outputs as peak loading (g) per activity were averaged. ANOVA, correlation analyses and Bland–Altman plots were computed to determine validity of accelerometers using GRF. There was a main effect of task with increasing acceleration values in tasks with increasing locomotion speed and landing height (P < 0.001). Data from ACT and GEN correlated with GRF (r = 0.90 and 0.89, respectively) and between each other (r = 0.98), but both accelerometers consistently overestimated GRF. The new generation of accelerometer models that allow raw signal detection are reasonably accurate to measure impact loading of bone in children, although they systematically overestimate GRF.  相似文献   

Effects of changing speed on knee and ankle joint load during walking and running     

Ana Cristina de David  Felipe Pivetta Carpes  Darren Stefanyshyn 《Journal of sports sciences》2015,33(4):391-397

Joint moments can be used as an indicator of joint loading and have potential application for sports performance and injury prevention. The effects of changing walking and running speeds on joint moments for the different planes of motion still are debatable. Here, we compared knee and ankle moments during walking and running at different speeds. Data were collected from 11 recreational male runners to determine knee and ankle joint moments during different conditions. Conditions include walking at a comfortable speed (self-selected pacing), fast walking (fastest speed possible), slow running (speed corresponding to 30% slower than running) and running (at 4 m · s^?1 ± 10%). A different joint moment pattern was observed between walking and running. We observed a general increase in joint load for sagittal and frontal planes as speed increased, while the effects of speed were not clear in the transverse plane moments. Although differences tend to be more pronounced when gait changed from walking to running, the peak moments, in general, increased when speed increased from comfortable walking to fast walking and from slow running to running mainly in the sagittal and frontal planes. Knee flexion moment was higher in walking than in running due to larger knee extension. Results suggest caution when recommending walking over running in an attempt to reduce knee joint loading. The different effects of speed increments during walking and running should be considered with regard to the prevention of injuries and for rehabilitation purposes.  相似文献   

Intentional thought dynamics during exercise performed until volitional exhaustion

Using a non-linear approach, intentional dynamics of thoughts were examined during constant cycling performed until volitional exhaustion. Participants (n = 12) completed two sessions at 80% W_max. Their (1) intrinsic thought dynamics (i.e., no-imposed thoughts condition) and (2) intentional thought dynamics (i.e., imposed task-unrelated thoughts condition; TUT) were recorded and then classified into four categories: internal and external TUT (TUT-I, TUT-E) and external and internal task-related thoughts (TRT-E, TRT-I). The probability estimates for maintaining each thought category stable, the rate of switching from one category to another, and the entropy dynamics along the testing procedure were assessed and compared through time phase. Friedman ANOVA tests revealed a significant effect of effort increase on thought contents only in the imposed TUT test. While TUT-I probabilities decreased significantly (P < .001) as effort increased, TRT-I probabilities increased (P < .05). Moreover, the entropy to the entire thought dynamics increased at the outset of task performance and decreased upon approaching volitional exhaustion (P < .001). As time spent in constant effort increased, and volitional exhaustion approached, task relatedness (TUT, TRT), direction (internal, external), and entropy of thought contents changed unintentionally providing further evidence for a nonlinear dynamics of attention focus.  相似文献
