Despite several studies having been conducted to examine organizational image from a business perspective, there has not been adequate research in the area of perceived image in nonprofit organizations such as universities. Thus, the purpose of this study was to examine the factors contributing to university image, from the postgraduate students’ point of view. In addition, the impact of the students’ perceived university image on their organizational trust was examined. The population of this study consisted of postgraduate students in 10 of the top Iranian universities. Questionnaires were used to collect the required data. The findings indicated the difference between current practices and ideal values of the factors contributing to the university image. Based on our findings, the factors contributing to university image range from internal and international reputation, university members, and academic planning, to university environment. Furthermore, we found that university image has a significant impact on students’ trust in their university. 相似文献

Corrosion is one of the main causes of deterioration in steel structures. Loss of thickness in flanges and web of corroded steel beams leads to reduction in section properties which can reduce the lateral torsional buckling capacity of the member. In this paper, thickness loss data were compiled from four samples of corrosion damaged I-beams removed from a petro-chemical plant. Visual examination of the four corroded beams showed that they were corroded uniformly. To improve the accuracy of the results, a large number of measurements for surface roughness were taken for each beam, totally 770 values to obtain the average thickness of flanges and web of each beam. The data was used to develop a corrosion decay model in order to calculate the percentage remaining lateral torsional buckling capacity of long and short span beams which are laterally unrestrained. To estimate the percentage of remaining lateral torsional buckling capacity in the corroded damaged I-beams, the readily available minimum curves for different types of universal beams in conj unction with information on the thickness loss were used. The results can be used by practicing engineers for better estimation on the service life of deteriorated steel structures. 相似文献

The purpose of this study was to evaluate the traction characteristics of four different stud configurations on Fédération Internationale de Football Association (FIFA) 2-Star, third-generation artificial soccer turf. The investigated stud configurations were hard ground design, firm ground design, soft ground design, and an experimental prototype. The concept of this study combines performance, perception, biomechanical, and mechanical testing procedures. Twenty-five soccer players took part in the different testing procedures. Variables of this study were: running times, subjective rankings/ratings, ground reaction forces, and mechanical traction properties. Statistical discrimination between the four stud configurations was shown for performance, perception, and biomechanical testing (p < 0.05). Unsuited stud configurations for playing on artificial turf are characterized by less plain distributed and pronounced studs. 相似文献

E-Government and E-Government development project studies have been conducted in most industrialized societies, as well as in Iran. Due to their nature and structure, E-Government development projects have numerous political, social, and economic impacts on society. Given the incorporation of significant capital, human resources, information, and political commitments, these projects are considered quite vital to society. Following the systematic pre-implementation activities of E-Government development projects is critical for the success of such projects; ignoring such issues leads to various problems during E-Government project implementation. This research aims to explore and detect the success indicators for pre-implementation activities of E-Government development projects, evaluate the validity of these indicators, and investigate the indicators' status in the Fuel Smart Card Project. The researcher has also provided some suggestions on the successful implementation of E-Government development projects. 相似文献

Rotary kiln is the central and the most complex component of cement production process. It is used to convert calcineous raw meal into cement clinkers, which plays a key role in quality and quantity of the final produced cement. This system has complex nonlinear dynamic equations that have not been completely worked out yet. In conventional modeling procedure, a large number of the involved parameters are crossed out and an approximation model is presented instead. Therefore, the performance of the obtained model is very important and an inaccurate model may cause many problems for designing a controller. This study presents hierarchical wavelet TS-type fuzzy inference system (HWFIS) for identification of cement rotary kiln. In the proposed method, wavelet fuzzy inference system (WFIS) with two input variables is used as sub-model in a hierarchical structure and gradient descent (GD) algorithm is chosen for training parameters of antecedent and conclusion parts of sub-models. The results show that the proposed method has higher performance in comparison with the other models. The data collected from Saveh White Cement Company is used in our simulations. 相似文献

The purpose of this study was to evaluate the effect of a special sex education program in sexual health on Iranian newly‐wed couples. A sample of 64 couples referred to three health centers of Tehran Medicine University, a few months prior to their marriage, were divided into case and control groups. The case group received three lecture sessions given by the researcher. These lectures consisted of different aspects of sexuality such as reproductive and sexual health, the sexuality response cycle and sexual communication. The control group received only the lectures that are presented normally in the marriage preparation program, based on family planning and personal health. Six months after the program, we assessed the sexual satisfaction, healthy behaviors and sexual health of the two groups. The results indicate that the sexual health in the case group is significantly improved compared with the control group. 相似文献

This paper takes up understandings of organisations where practices constitute and frame past and present work, as well as
future work practice possibilities. Within this view, work practices, and thus organisations, are both perpetuated and varied
through employees’ enactments of work. Using a practice lens, we are particularly interested in the ways workers simultaneously
maintain and alter practices in their workplace—we characterise this as re-making one’s job. This perspective challenges ways
in which managers often depict jobs and everyday work—as rational, linear and easily describable. We suggest that workers
at various levels of responsibility contribute more to the formation of organisational practices than is often assumed. The
processes of re-making jobs and remaking organisational practices create tensions that we posit as sites for learning. This
paper addresses these issues through a focus on work practices in two Australian organisations that have been undergoing significant
cultural change. 相似文献

This paper presents a precise solution to predict the behavior of steel fiber reinforced concrete (SFRC) under the four point
bending test (FPBT). All the force components at the beam section (before and after cracking) are formulated by applying these
assumptions: a realistic stress-strain model is used for concrete behavior in compression, a linear response is considered
for the uncracked tension region in a concrete constitutive model, and an exponential relationship is proposed as a stress-crack
opening in the crack region which requires two parameters. Then the moment capacity of the critical cracked section is calculated
by using these forces and satisfying equilibrium law at the section. Parametric studies are done on the behavior of SFRC to
assess the sensitivity of the solution. Finally, this solution is validated with some existing experimental data. The result
shows the proposed solution is able to estimate the behavior of SFRC under FPBT. 相似文献

Abstract Capacity Development is needed in the Iranian Agricultural System. Integrating Information and Communication Technologies (ICTs) in the agricultural research system is an appropriate capacity development mechanism. The appropriate application of ICTs and information such as a National Agricultural Information System requires a systemically developed strategic plan, based on identifying and recognizing system-wide organizational implications. In this regard, this paper focuses on the implications of integrating ICTs in the Iranian agricultural research system. To this aim, the authors conducted a survey research study using qualitative analysis of interview data from a select sample of agricultural researchers and agricultural faculty members. After designing an interview protocol and doing interviews with the select sample of agricultural researchers and faculty members (n = 29), a qualitative procedure was used to analyze the data, based on conceptual extraction and thematic categorization of statements. Categories included guidelines, expected outcomes, challenges and barriers of appropriate ICTs integration in the Iranian agricultural research system. In addition, different phases of the ICTs integration process were identified in the form of a pathway diagram. Finally, based on related Iranian lessons learned, which are explained in this research, some appropriate mechanisms for integrating ICTs in national agricultural research system were indicated. 相似文献
