During the last decade, intellectual capital (IC) and intangible assets have been widely considered as critical tool to deliver successful business in an intensive-knowledge environment. Accordingly, the main goal of this paper is therefore to develop and prioritize the most important indicators of intellectual capital in knowledge-based industries. Based on an extensive literature review, a valid and reliable questionnaire was designed. In order to data gathering, it was sent out to participants from both academic and university who qualified well in pharmaceutical practice. In order to exact prioritization of indicators, fuzzy TOPSIS technique as a MADM model was used. The fuzzy TOPSIS results revealed participants remark high concerns especially about knowledge and skills of managers and employees regarding to human capital, high concerns particularly about positive climate, ratio of investment in R&D and numbers of R&D projects according to structural capital, while considering the relational capital, more attention was paid to customers and strategic cooperation such as alliances and licensing. 相似文献

AbstractThe study is a mixed-methods investigation of how urban schools are succeeding. The study surveyed 28 former students from urban schools in Oxnard, California. The qualitative responses represent themes that align to a high level of school connectedness and social–emotional learning (SEL) as key indicators of a successful urban school district. The responses also aligned with the thematic structures of the assets and relationships frameworks and to SEL standards. 相似文献

Brucellosis, a zoonosis caused by four species of brucella, has a high morbidity. Brucella melitensis is the main causative agent of brucellosis in both human and small ruminants. As an alternative to conventional antibiotics,
medicinal plants are valuable resources for new agents against antibiotic-resistant strains. The aim of this study was to
investigate the usage of native plants for brucellosis treatment. For this purpose, the anti-brucella activities of ethanolic
and methanolic extracts of Salvia sclarea, Oliveria decumbens, Ferulago angulata, Vitex pseudo-negundo, Teucrium polium, Plantago ovata, Cordia myxa, and Crocus sativus were assessed. The activity against a resistant Br. melitensis strain was determined by disc diffusion method at various concentrations from 50–400 mg/ml. Antibiotic discs were also used
as a control. Among the evaluated herbs, six plant (Salvia sclarea, Oliveria decumbens, Ferulago angulata, Vitex pseudo-negundo, Teucrium polium, and Crocus sativus) showed anti-brucella activity. Oliveria decumbens was chosen as the most effective plant for further studies. A tested isolate exhibited resistance to tetracycline, nafcillin,
oxacillin, methicillin, and colistin. Minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC)
values for Oliveria decumbens against resistant Br. melitensis were the same (5 mg/ml), and for gentamicin they were both 2 mg/ml. Time-kill kinetics for a methanolic extract of Oliveria decumbens was 7 h whereas for an ethanolic extract it was 28 h. Also, Oliveria decumbens extracts showed a synergistic effect in combination with doxycycline and tetracycline. In general, the similar values of
MIC and MBC for Oliveria decumbens suggest that these extracts could act as bactericidal agents against Br. melitensis. In addition to Oliveria decumbens, Crocus sativus and Salvia sclarea also had good anti-brucella activity and these should be considered for further study. 相似文献

Objective: To report a mathematical function that characterizes the double-pass line spread function (LSF) of the human eye. Determining analytical functions that represent the double-pass LSF is important because it allows modeling the optical performance of the eye. Methods: Optical section retinal images, generated in normal human eyes using a modified slit-lamp biomicroscope, were analyzed to derive the double-pass LSF by plotting the intensity distribution of laser light reflected/ scattered from the vitreoretinal interface. Three mathematical functions (Lorentzian, Gaussian, exponential) were fitted to the double-pass LSF and the root mean square error (RMSE) was calculated to provide a measure of the goodness of fit. Results: The Lorentzian function provided the best representation of the double-pass LSF of normal human eyes. The full width at half maximum (FWHM) of the Lorentzian fitted curve was positively correlated with age, indicating that the double-pass LSF broadens with age. Furthermore, the goodness of fit of the Lorentzian function was significantly better in younger subjects as compared with older subjects, suggesting that the fitted function to the double-pass LSF may vary according to age. Conclusion: The results demonstrate an age-related change in the double-pass LSF width and the goodness of fit of the Lorentzian function. 相似文献

The Specialised Vocational Training Institutions (IMPro) in France have recently entered into a difficult, but important period of time. During the past few years, IMPro have faced increasing demand from the public and government to provide quality service to adolescents with intellectual disabilities. IMPro have been also faced with the challenge of being accountable for the low employment rate of adolescents with intellectual disability and their failure to obtain and/or maintain jobs due to lack of technical and social skills. The purpose of the present work was to respond to the increasing and urgent needs in IMPro by designing and developing a training system to enhance organisational productivity, increase employment rate, and eliminate the problems faced by workers with intellectual disabilities. This article describes the process of organisational changes in IMPro using systems thinking. It discusses the model, methods, tools, and techniques used in designing, developing, implementing, and evaluating the new system of training in IMPro in an attempt to improve the quality, effectiveness, and efficiency of their training programs. 相似文献

The purpose of this paper is to describe the evaluation results of using an interactive design model for the development of
an online course. Specifically, it examines: (a) how an interactive design model was used to develop collaborative and cooperative
learning activities; (b) how activities were structured to promote the level and quality of communications among students,
as peers, and between students and the instructors; and (c) how students responded to such interactive design model. The paper
also provides information about the delivery process and describes what happened when this interactive model was fully implemented
and used. 相似文献

During the recent years several chaotic image encryption algorithms have been proposed, but most of them encountered some drawbacks such as small key space, low speed, lack of robustness and low security. In this paper, we have proposed an image algorithm based on the combination of a one-dimensional polynomial chaotic map and a piecewise nonlinear chaotic map. Theoretical analysis and computer simulations, both confirm that the new algorithm possesses high security, robust fast encryption speed for practical image encryption and solves the problem of small key space. 相似文献
