E-government evaluation: a framework and case study   总被引：2，自引：0，他引：2  

M. P. Gupta  Debashish Jana 《Government Information Quarterly》2003,20(4):226-387

The importance of measuring the performance of e-government cannot be overemphasized. In this paper, a flexible framework is suggested to choose an appropriate strategy to measure the tangible and intangible benefits of e-government. An Indian case study of NDMC (New Delhi Municipal Corporation) has been taken up for analysis and placement into the framework. The results obtained suggest that to have a proper evaluation of tangible and intangible benefits of e-government, the projects should be in a mature stage with proper information systems in place. All of the e-government projects in India are still in a nascent stage; hence, proper information flow for calculating ‘return on e-government’ considering tangible and intangible benefits cannot be fully ascertained.  相似文献   

Evidence for color vision in procyonides: Comparison between diurnal coatis (Nasua) and nocturnal kinkajous (Potos flavus)     

Monika Chausseil 《Learning & behavior》1992,20(3):259-265

The color-vision capacity of two species of procyonides was analyzed using a binary simultaneous discrimination paradigm. To make hue the only salient cue, the color sets of red, yellow, green, and blue were each presented in five different saturation intervals and were tested against a variety of brightness steps. Unlike the nocturnal kinkajous, the diurnal coatis showed highly significant discriminative performance on the color problems, especially in tests on blue and yellow, yet failed to differentiate unsaturated green from achromatic stimuli. The results are discussed with respect to procedural variables and the utility of color discrimination in the coati’s natural environment.  相似文献

High-Ability Grouping: Benefits for Gifted Students’ Achievement Development Without Costs in Academic Self-Concept     

Franzis Preckel  Isabelle Schmidt  Eva Stumpf  Monika Motschenbacher  Katharina Vogl  Vsevolod Scherrer  Wolfgang Schneider 《Child development》2019,90(4):1185-1201

Effects of full-time ability grouping on students’ academic self-concept (ASC) and mathematics achievement were investigated in the first 3 years of secondary school (four waves of measurement; students’ average age at first wave: 10.5 years). Students were primarily from middle and upper class families living in southern Germany. The study sample comprised 148 (60% male) students from 14 gifted classes and 148 (57% male) students from 25 regular classes (matched by propensity score matching). Data analyses involved multilevel and latent growth curve analyses. Findings revealed no evidence for contrast effects of class-average achievement or assimilation effects of class type on students’ ASC. ASC remained stable over time. Students in gifted classes showed higher achievement gains than students in regular classes.  相似文献

Prediction of vibrations induced by trains on line 8 of Beijing metro   总被引：1，自引：0，他引：1  

Shashank GUPTA  Geert LOMBAERT  Geert DEGRANDE 《浙江大学学报(A卷英文版)》2010,11(4):280-293

This paper mainly discusses the problem of ground-borne vibrations due to the planned line 8 of Beijing metro which passes under the National Measurement Laboratory. A lot of vibration sensitive equipments are placed in the laboratory. It is therefore necessary to study the impact of vibrations induced by metro trains on sensitive equipments and important to propound a feasible vibration mitigation measure. Based or1 the coupled periodic finite element-boundary element （FE-BE） method, a 3D dynamic track-tunnel-soil interaction model for metro line 8 has been used to predict vibrations in the free field induced by trains running at variable speeds between 30 km/h and 80 km/h. Four types of track structures commonly used on the Beijing metro network have been considered： （1） high resilience direct fixation fasteners, （2） Vanguard fasteners, （3） a floating slab track and （4） a floating ladder track. For each of these track types, the vibration isolation efficiency has been compared. The results of the numerical study can be used to predict vibrations in nearby buildings and to decide upon effective vibration countermeasures.  相似文献   

Examining the complexities of school-museum partnerships     

Preeti Gupta  Jennifer Adams  James Kisiel  Jennifer Dewitt 《Cultural Studies of Science Education》2010,5(3):685-699

We examine the research conducted by Kang, Anderson and Wu by discussing it in a larger context of science museum-school partnerships. We review how the disconnect that exists between stakeholders, the historical and cultural contexts in which formal and informal institutions are situated, and ideas of globalization, mediate the success for formal-informal partnerships to be created and sustained.  相似文献   

To Establish the Reference Intervals of Lipid Profile in Punjab     

Vaneet Kaur  Minni Verma  Amandeep Kaur  Shalini Gupta  Kamaljit Singh 《Indian journal of clinical biochemistry : IJCB》2012,27(3):290-295

Overnight fasting samples of 1,031 apparently healthy people of Punjab visiting the hospital over a period of 3 years were tested for serum lipid profile. The mean ± SD of serum total cholesterol, triglycerides, high density lipoprotein cholesterol, low density lipoprotein cholesterol and very low density lipoprotein cholesterol in mg/dl were 182.2 ± 33.9, 122.4 ± 33.4, 44.1 ± 6.8, 113.9 ± 32.0, 24.6 ± 7.1 respectively. When these subjects were grouped according to age and sex, no appreciable difference was observed between most of the groups. Serum triglycerides were found to be low and HDL-C was high in females when compared with males of similar age and vice versa. With advancing age, total cholesterol and low density lipoprotein cholesterol levels were found to be higher in women. The present study suggests that the obtained lipid values should be taken into consideration during clinical evaluation.  相似文献   

Stress-related psychological factors for back pain among athletes: Important topic with scarce evidence     

Jahan Heidari  Monika Hasenbring  Jens Kleinert  Michael Kellmann 《European Journal of Sport Science》2017,17(3):351-359

Health issues represent a frequent problem for athletes, as this particular demographic is repeatedly confronted with physically and psychologically stressful situations. Back pain (BP) materialises as comparatively common health problem being regarded as functionally limiting and psychologically straining burden for athletes. According to research conducted on athletes with BP, biomechanical and physiological mechanisms emerge as influential, whereas stress-related psychological factors appear to be neglected. For athletic injuries, the essential impact of psychological processes on injury occurrence and return from injury has already been corroborated. Hence, the aim of this literature review is to: (1) introduce a conceptual differentiation between injuries and BP; (2) summarise the results obtained regarding stress-related psychological aspects for injuries; and (3) connect the injury research to the state-of-the-art evidence regarding stress-related factors for BP among athletes. A distinction between injuries and BP could be established based on previous definitions, despite the fact that a considerable overlap between both concepts prevails. Injuries can be attributed to a physical origin, whereas BP frequently lacks this physical criterion. For BP, our enquiry yielded four studies including psychological measures of stress – with two studies specifically examining the association between BP and psychological stress among athletes longitudinally. Abundant findings from the general population support the importance of considering psychological and specifically stress-related factors in BP prevention and rehabilitation, but evidence related to the athletic field remains elusive. Further scientific investigations with a wider methodological approach are needed to deepen the knowledge about the crucial relationship between psychological stress, BP, and athletes.  相似文献
