Examining the antecedents of e-loyalty intention in an online reservation environment     

Samar Mouakket  Mohammad Ahmad Al-hawari 《The Journal of High Technology Management Research》2012,23(1):46-57

Online reservation has increased significantly in recent years. Understanding how customers behave towards this technology is considered to be important to interested parties, such as travel agencies and tourism marketing managers, in order to enable them to improve their marketing strategies, which would, in turn, allow them to retain their customers. This paper presents findings about the antecedents of e-loyalty intention towards online reservation among 288 respondents in the United Arab Emirates. The research examines the role of e-service quality, hedonic and utilitarian values, satisfaction, and subjective norms in motivating loyalty intention towards online reservation. The results show that e-service quality has a significant influence on hedonic and utilitarian values, which, in turn, affect customer satisfaction. Moreover, satisfaction and subjective norms positively affect e-loyalty intention towards online reservation.  相似文献   

An interdisciplinary overview and intelligent control of human prosthetic eye movements system for the emotional support by a huggable pet-type robot from a biomechatronical viewpoint     

Faezeh Farivar  Mahdi Aliyari Shoorehdeli  Mohammad Teshnehlab 《Journal of The Franklin Institute》2012,349(7):2243-2267

Despite active research and significant progress in the last three decades on control of human eye movements, it remains challenging issue due to its applications in prosthetic eyes and robotics. Till now, no considerable investigation of this subject is presented in the interdisciplinary sciences. The goal of this paper is to present a distinguished survey of existing literature on the intelligent control of the human eye movements system applied in a huggable pet-type robot as a biomechatronic system.In this study, the basic knowledge of human eye movements control is explained to show how the neural networks in the brainstem control the human eye movements. The geometry and model of human eye movements system are investigated and this system is considered as a nonlinear control system. The specified model may only be an academic exercise. It can have scientific importance in understanding of the human movement system in general. Also, it can be useful for robotics.Intelligent methods such as artificial neural networks and fuzzy neural networks are proposed to control the human eye movements and numerical simulations are presented. It is discussed that the intelligent controls applied to control of human eye movements system are emulated from the neural controls in biological system.  相似文献   

Evaluation of the remaining lateral torsional buckling capacity in corroded steel members     

Yasser Sharifi  Reza Rahgozar 《浙江大学学报(A卷英文版)》2010,11(11):887-897

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   

Growth and yield of rice as affected by transplanting dates and seedlings per hill under high temperature of Dera Ismail Khan, Pakistan     

Baloch MS  Awan IU  Hassan G 《Journal of Zhejiang University. Science. B》2006,7(7):572-579

Studies were initiated for two consecutive years to find out the effect of time of transplanting and seedlings hill^-l on the productivity of rice in Dera Ismail Khan district of North West Frontier Province （NWFP）, Pakistan. The experiment was laid out in a randomized complete block design with split plot arrangements. Main plots consisted of four transplanting dates viz. 20th and 27th of June and 4th and 1 lth of July while sub-plots contained 1, 2, 3 or 4 seedlings hill^-1. Among transplanting dates, June 20th planted crop gave highest paddy yield and net return with I seedling hill^-1. It explains that the use of more seedlings hill^-1 not only adds to cost but is also a mere wastage of natural resources. Based on research findings, we conclude that the use of I seedling hill^-1 is most appropriate for timely sowing otherwise 4 seedlings hill^-1 should be used to compensate for the yield gap in late transplanted rice.  相似文献   

Rorty's Approach to Cultural Difference: The Conflict between Solidarity and Procedural Liberalism     

Seyed Mohammad Ali Taghavi 《Culture, Theory & Critique》2013,54(2):123-138

Although Richard Rorty's controversial thought has been the subject of many works, there has not been much discussion about his approach to cultural difference. The purpose of this article is to examine how Rorty sees cultural differences philosophically and how he deals with them politically. For him, rationality, morality and even the scope of moral responsibility towards others are defined in terms of solidarity with a particular community and ‘ethnocentrism’, rather than in terms of a universal and metaphysically derived set of criteria. It can be argued that since language, language games and values are mainly components of culture, the latter is one of the most significant communities with which Rorty is concerned, though he is not explicit about it. Nevertheless, Rorty does not think that the moral and philosophical significance of communities, particularly cultural communities, should be reflected in politics. The main argument of the article is that there is an unresolved tension in Rorty's thought between philosophical, moral and emotional attribution of significance to communities and arguably cultural communities, and a disregard for them in the political sphere. This paves the way for outlining an approach to cultural difference that is more just and even more in harmony with Rorty's own philosophy.  相似文献   

The Normal Family of Linear Systems     

F. M. Reza 《Journal of The Franklin Institute》1985,320(6)

The normal family of linear (time-variant) n-ports is introduced as the most natural extension of ordinary scalar driving-point immittance behaviour. The normality induces a certain symmetry and simplicity which merits due emphasis in future n-port research investigations. As an application of the concept of normality the overdamped-underdamped criterion is extended to n-ports. Also, an interesting problem of maximal power transfer is solved and the absolute energy invariant index calculated. This paper invites attention to the development of circuit synthesis procedures based on the algebraic structure of the normal family.  相似文献   

Thyroid hormones status during pregnancy in normal Iranian women     

Nosratollah Zarghami  Mohammad Rohbani-Noubar  Ali Khosrowbeygi 《Indian journal of clinical biochemistry : IJCB》2005,20(2):182-185

Pregnancy is associated with significant, but reversible changes in thyroid function studies, which are among the most profound seen as a result of a normal physiologic state. The present study was carried out to find out alterations in thyroid function tests in each trimester in normal pregnant women as compared to non-pregnant women in Tabriz-Iran. A case-control study designed with 229 normal pregnant women that randomly selected from the first (64 samples), the second (92 samples), and the third (73 samples) trimesters and 250 randomly selected non-pregnant healthy female controls. Age range in both groups was 16–40 years. Thyroid function tests carried out by measuring serum levels of thyroid stimulating hormone (TSH), free and total thyroxin (FT₄, TT₄), and free and total triiodothyronine (FT₃, TT₃) by commercially available radio immunoassay kits. We found that mean TT₄ increased progressively during pregnancy. Our study showed increasing in serum levels of TT₃ in the second trimester and then declining during the third trimester compared with non-pregnant women. We showed that FT₄ strongly decreased during the third trimester. Free T₃ showed declining in the second and third trimesters. Mean TSH did not show significant difference in each trimester compared with non-pregnant women. The thyroid function tests in pregnancy should be interpreted against gestational age-related reference intervals to avoid mis-interpretation of thyroid function during pregnancy.  相似文献   

Restrictions of the derivatives of positive real functions     

F.M. Reza 《Journal of The Franklin Institute》1981,312(5):335-343

Dissipative operators appear in abundance in the study of dynamical systems. In the classical circuit theory they are presented as Positive Real Functions. The coefficients of the Taylor expansion of PRF (driving-point impedance or admittance) must satisfy certain derived inequalities. A method is suggested for obtaining restrictions of the derivative of Positive Real Functions (Dissipative Operators).  相似文献
