Learning of musculoskeletal ligament stress testing in a gross anatomy laboratory     

Krause DA  Youdas JW  Hollman JH 《Anatomical sciences education》2011,4(6):357-361

Human anatomy in physical therapy programs is a basic science course serving as a foundation for subsequent clinical courses. Integration of anatomy with a clinical emphasis throughout a curriculum provides opportunities for reinforcement of previously learned material. Considering the human cadaver laboratory as a fixed cost to our program, we sought opportunities to add value to the resource via vertical integration into a clinical skills course taught later in the curriculum. We designed an opportunity for second-year physical therapy students to revisit the human anatomy laboratory to study select clinical musculoskeletal tests and the associated anatomy in a clinically relevant context. Students performed select orthopedic ligament test on human cadavers, then incised specific structures and repeated the tests. Students were able to feel and visualize the function of pertinent anatomy associated with the clinical tests. Ninety-five percent of respondents reported that the ligament stress testing experience enhanced their understanding of orthopedic clinical tests with 91% reporting an enhanced understanding of anatomy related to specific clinical tests. Likewise, the experience was perceived as enjoyable and valuable with 86% of respondents reporting the experience as enjoyable and 100% responding the experience should continue as part of the curriculum.  相似文献   

Stabilizability of complex complex-valued memristive neural networks using non-fragile sampled-data control     

Ruimei Zhang  Deqiang Zeng  Ju H. Park  Kaibo Shi  Yajuan Liu 《Journal of The Franklin Institute》2021,358(4):2320-2345

This paper investigates the stability and stabilizability of complex-valued memristive neural networks (CVMNNs) with random time-varying delays via non-fragile sampled-data control. Taking the influence of gain fluctuations into account, a non-fragile sampled-data controller is designed for CVMNNs. Compared with the existing control schemes, the one here is more applicable and can effectively save the communication resources. The assumption on activation functions of CVMNNs is relaxed by only needing the complex-valued activation functions satisfying the Lipschitz condition. By constructing a suitable Lyapunov–Krasovskii functional (LKF), new stability and stabilizability criteria are derived for CVMNNs. Different from the existing results with the maximum absolute values of memristive connection weights, our ones are based on the average values of the maximum and minimum of the memristive connection weights. Finally, numerical simulations are given to validate the effectiveness of the theoretical results.  相似文献   

Image watermarking using separable fractional moments of Charlier–Meixner     

M. Yamni  H. Karmouni  M. Sayyouri  H. Qjidaa 《Journal of The Franklin Institute》2021,358(4):2535-2560

This paper proposes a new set of discrete orthogonal separable moments of fractional order, named Fractional Charlier–Meixner Moments (FrCMMs). The latter are constructed from fractional Charlier polynomials (FrCPs) and fractional Meixner polynomials (FrMPs) proposed in this paper. The proposed FrMPs are constructed algebraically using the spectral decomposition of classical Meixner polynomials and singular value decomposition (SVD). The proposed FrCMMs generalize the separable moments of Charlier–Meixner of integer order (CMMs). In addition, FrCMMs are characterized by the polynomial parameters and by the fractional orders of the two fractional kernel functions of Charlier and Meixner, which allows them to be used efficiently for different applications such as local and global image reconstruction and image watermarking. Based on the proposed FrCMMs, a new watermarking scheme for copyright protection of digital images in the transform domain is proposed where the watermark is embedded in the FrCMM coefficients leading to an efficient watermarking scheme in terms of imperceptibility, robustness and security. The performances of the proposed moments are evaluated and compared with discrete fractional moments existing in the literature and with classical separable moments of integer order.  相似文献   

An unsupervised heuristic-based approach for bibliographic metadata deduplication     

Eduardo N. Borges  Moisés G. de Carvalho  Renata Galante  Marcos André Gonçalves  Alberto H.F. Laender 《Information processing & management》2011

Digital libraries of scientific articles contain collections of digital objects that are usually described by bibliographic metadata records. These records can be acquired from different sources and be represented using several metadata standards. These metadata standards may be heterogeneous in both, content and structure. All of this implies that many records may be duplicated in the repository, thus affecting the quality of services, such as searching and browsing. In this article we present an approach that identifies duplicated bibliographic metadata records in an efficient and effective way. We propose similarity functions especially designed for the digital library domain and experimentally evaluate them. Our results show that the proposed functions improve the quality of metadata deduplication up to 188% compared to four different baselines. We also show that our approach achieves statistical equivalent results when compared to a state-of-the-art method for replica identification based on genetic programming, without the burden and cost of any training process.  相似文献

Autonomous cleaning system for Dubai International Airport     

H. Sadjadi 《Journal of The Franklin Institute》2011,348(1):112-124

This paper outlines the development of a robotic system designed to clean the outer surface of elliptic tapered structures such as Dubai airport concourse. The designed system consists of two identical cleaning satellites connected to a main unit and provides cleaning coverage up to 83° tilt from the horizontal surface of the concourse. The controller design, sensors, localization, and employed communication techniques are presented in this paper along with the final results of the implemented prototype. The system features redundant locomotion to ensure safe and reliable operation while maintaining autonomy and flexibility.  相似文献   

Demand articulation in emerging technologies: Intermediary user organisations as co-producers?     

Wouter P.C. BoonAuthor Vitae  Ellen H.M. Moors Author VitaeStefan Kuhlmann Author Vitae  Ruud E.H.M. Smits Author Vitae 《Research Policy》2011,40(2):242-252

User involvement is assumed to be beneficial to innovation processes. Intermediary user organisations contribute to articulating societal demands for innovations. However, the learning processes inside these organisations are still not understood well. Therefore, this paper empirically investigates intermediaries using an event history approach. It yields characteristic learning mechanisms, e.g. concerning the management of expectations or actively building a case. If intermediaries overcome challenges regarding positioning, representation and the level of proactivity, they can play a precarious role in demand articulation in the context of new technologies.  相似文献   

Autonomy-connectedness, acculturation, and independence-interdependence among various cultural groups in a multicultural society     

Marrie H.J. Bekker  Judit Arends-TóthMarcel A. Croon 《Int J Intercult Relat》2011,35(3):368-376

The present study was aimed at investigating the relationships between autonomy-connectedness and adherence to independent and interdependent values in second-generation Dutch immigrant women with a background in countries labeled as collectivistic, and same-aged indigenous Dutch women (N = 180 and N = 157, respectively). Both groups completed the Autonomy-Connectedness Scale (ACS-30; Bekker & Van Assen, 2006) and the Self-Construal Scale (Singelis, 1994). Additionally, those with an immigrant background filled out the Acculturation Questionnaire (Arends-Tóth & Van de Vijver, 2003). Contrary to expectations, both groups had similar levels of self-awareness, whereas the indigenous Dutch women were - after controlling for educational level - more sensitive to others. In both groups, but even more in the group with an immigrant background, adherence to independent values appeared to contribute substantially and positively to self-awareness as well as capacity for managing new situations, and negatively to sensitivity to others. In addition, adherence to interdependent values contributed, for both groups, positively to sensitivity to others, and, for those with an immigrant background, negatively to self-awareness. The ACS-30 appeared to be useful for assessing autonomy-connectedness in the immigrant groups that participated in the study. The results confirm that a simple distinction between native and immigrant Dutch groups in terms of being self- or other-focused should be rejected, and give rise to further, clinically relevant research questions.  相似文献   

Survey results of the training, nutrition, and mental preparation of triathletes: practical implications of findings     

Dolan SH  Houston M  Martin SB 《Journal of sports sciences》2011,29(10):1019-1028

Although triathlon is growing in popularity at a remarkable rate, it has not been extensively studied. The aims of this research were to identify preparation strategies used by triathletes and to categorize these strategies according to gender and consultation with triathlon coaches. Survey data collected from 401 triathletes (207 males, 194 females) revealed training, nutritional, and mental preparation habits. Most participants engaged in strength training, consumed food and/or fluids during and after training, set training and competition goals, and applied mental preparation strategies during training and the hour before racing. Water was the most commonly consumed fluid; positive self-talk was the most used mental strategy. Participants were more likely to consult with a triathlon coach than a nutrition or sport psychology professional. Athletes with more years of experience in triathlon and those competing in longer distances were more likely to consult a triathlon coach. Female triathletes were more likely than male triathletes to train with others, use mental preparation strategies, and report feeling anxious before competitions. More male triathletes reported using nutritional supplements during training than their female counterparts. These findings add to the limited research base on triathletes' training habits, and hopefully will help guide practitioners who work with this group. The results provide guidance for collaborative efforts among training, nutrition, and mental health professionals to best support triathletes.  相似文献   

Home advantage in professional tennis     

Koning RH 《Journal of sports sciences》2011,29(1):19-27

Home advantage is a pervasive phenomenon in sport. It has been established in team sports such as basketball, baseball, American football, and European soccer. Attention to home advantage in individual sports has so far been limited. The aim of this study was to examine home advantage in professional tennis. Match-level data are used to measure home advantage. The test used is based on logit models, and consistent specification is addressed explicitly. Depending on the interpretation of home advantage, restrictions on the specification of the model need to be imposed. We find that although significant home advantage exists for men, the performance of women tennis players appears to be unaffected by home advantage.  相似文献
