There is increasing evidence that exposure to stress during development can have sustained effects on animal phenotype and performance across life-history stages. For example, developmental stress has been shown to decrease the quality of sexually selected traits (e.g. bird song), and therefore is thought to decrease reproductive success. However, animals exposed to developmental stress may com...

OBJECTIVE The aim of the study was to determine the importance of β-hCG level on day 4 following methotrexate (MTX) administration, and the difference between β-hCG levels assessed on day 0 and day 4 in predicting treatment success. MATERIAL AND METHODS A total of 68 women with tubal pregnancy, treated with a single dose of MTX, were selected for this retrospective study. RESULTS The succes...

We consider the relationship between collegiate-football success and non-athlete student performance. We find that the team’s success significantly reduces male grades relative to female grades, and only in fall quarters, which coincides with the football season. Using survey data, we find that males are more likely than females to increase alcohol consumption, decrease studying, and increase p...

An extensive body of research has tested the DeLone and McLean (2003) information systems success model in many contexts. Surprisingly, few of these studies have applied it to e-commerce. A study by Wang (2008) represents one such initiative, but it is crucial to address several remaining gaps associated with that study. Moreover, no e-commerce success model has considered the Arab world, which...

This study examines the role of outcome expectations and satisfaction in influencing citizens’ intention to continue using electronic government services. In order to investigate the key factors that affect an individual’s use of Information and Communication Technology within the context of electronic government, a framework combining Social Cognitive Theory and Expectation-Confirmation Theory...

DeLone and McLean’s Information Systems Success model was validated empirically in many developed countries. However, it was not tested in Low-Income Countries (LICs) context where IT infrastructure is a serious hurdle for IS success. Testing the Model in LIC context assures generalizability and relevance of the model. This study looks at two research questions: (1) is the IS success model vali...

Despite the outstanding economic relevance of information systems in business and society, there exists no consensus among academics and practitioners how to measure the success of information systems. Therefore this paper makes a contribution to structure and classify the most recent research in IS success. This is done by providing an exhaustive overview of literature in the field of IS succe...

This study investigates website quality factors, their relative importance in selecting the most preferred website, and the relationship between website preference and financial performance. DeLone and McLean’s IS success model extended through applying an analytic hierarchy process is used. A field study with 156 online customers and 34 managers/designers of e-business companies was performed....

From time to time, large numbers of researchers investigate the success factors of B2C e-commerce systems. However majority of those were conceptual studies. Though some empirically validated studies were published on B2C e-commerce systems, very few focused on Asian consumers. The study aims to fill this gap by studying ecommerce success factors among Asian online consumers. Another important ...

Mobile technologies have changed the shape of learning for learners, society, and education providers. Consequently, mobile learning has become a core component in modern education. Nevertheless, introducing mobile learning systems does not automatically guarantee that learners will develop a positive behavioural intention to use it and therefore use it. Thus, acceptance-of-technology and syste...
