While traditional Saudi Arabian courtship is rigidly structured according to a set of Islamic codes of conduct, over the past decade, Saudis have increasingly turned to unconventional means of finding and courting a potential spouse: matrimonial Web sites. This research explores the debate in the literature on computer meditated communication regarding whether online settings provide rich information about other users, as they show that online interactions can provide more information about the opposite sex for users who belong to gender‐segregated societies than they can get through their offline lives. The article will shed some light on the interplay between young generations and their obsessions with the world of Internet dating and the societal norms and social conducts with which they are comfortable while living in Saudi Arabia. The article may contribute to the online dating literature by showing the similarities and differences between conservative, Islamic Saudi users and Western users when using Web sites to search for a potential mate. The research shows the power of both social and religious norms in affecting these users’ behaviors and decisions when using matrimonial Web sites.  相似文献

In the second half of the nineteenth century, and again in the middle of the twentieth century, federal, state, and local governments were involved in large-scale subsidizing and promoting of railroad infrastructure for economic development purposes. In the 1800s, public financial involvement centered on the expansion of railroads to develop the West. In the 1960s, 1970s, and early 1980s, public financial assistance focused on preserving rail freight services, and on restructuring the then oversized national rail network. In the 1990s and beyond, rail improvements and the need for public assistance are likely to be more incremental, with mostly local projects. Case study research was conducted on six local freight rail service projects, all of which had public sector investment. Five attributes were identified whose presence was associated with project success, or conversely, whose absence may have reduced the likelihood for project success. These success attributes should be used as an adjunct to sound economic analysis, and incorporated within future policies governing selection of local rail projects to receive public assistance.  相似文献

Structural walls of old historical structures are either blind or have openings for functional requirements. It is well known that in and out of plane responses of structural walls are affected by the size, locations, and arrangements of such openings. The purpose of this investigation is to study the window opening effects on static and seismic behaviors of historical masonry old mosques. Fatih Mosque, which was converted from a church, constructed in 914 in Trabzon, Turkey, is selected for this purpose. The mosque is being restored. Structural exterior walls of the mosque were made using stone and mortar materials. When the plaster on the walls was removed during the restoration, 12 window openings were found as blind on the exterior structural walls of the mosque. Within the scope of restoration works, it is aimed to open such blind windows. In order to investigate the effects of the window openings on the structural behavior of the mosque, 3D solid and finite elements models of the mosque with and without window openings are initially developed. The experimental dynamic characteristics such as frequency, damping ratio, and mode shapes of the current situation of the mosque, where some windows openings are blind, are determined using Ambient Vibration Testing. Then, the finite element model of the current situation of the mosque is updated using the experimental dynamic characteristics. The static and seismic time history analyses of the updated finite element model with and without window openings are carried out. Structural behaviors of the mosque with and without window openings are compared considering displacement and stress propagations.  相似文献
