Population reduction and disturbances may alter dispersal, mating patterns and gene flow. Rather than taking the common approach of comparing different populations or sites, here we studied gene flow via wind-mediated effective pollen dispersal on the same plant individuals before and after a fire-induced population drop, in a natural stand of Pinus halepensis. The fire killed 96% of the pine t...

the pollution of aquatic ecosystems may affect natural reproduction of fish populations by decreasing the fertilization efficiency. among the various sources of pollution, heavy metals are important group, being found in both freshwater and marine environment. the present study investigated changes of sperm characteristics of caspimyzon wagneri when exposed to manganese (mn). spermatozoids were...

Measuring information systems (IS) success is of great interest to both researchers and practitioners. This article examines multidimensional approaches to measuring IS success and explores the current state of IS success research through a literature review and by classifying articles published between 2003 and 2007. Based on a total of 41 academic journal and conference publications, the rele...

The main aim of this study is to develop a theoretical framework for the success of Web portals in promoting task innovation. This is deemed significant as yet little research has tackled this important domain from the business intelligence perspective. The D&M IS Success Model was used as a foundational theory and then was refined to match the context of the current research. Importantly, in t...

The mobile network-based Electrocardiography (m-ECG) system to be developed is expected to improve the overall referral processes and treatment of cardio vascular patients remotely located from physicians by eliminating or minimising the unpredictable elements such as poor sound quality, delay in transmission time and speed. The earlier physicians can treat heart attack patients, the lower the ...

Measuring the quality of mobile shopping (m-shopping) system provides retailers with a greater understanding of what improvements need to be made along the way to increase purchase intention and organizational performance. M-shopping is an alternative sales channel available to optimize marketing investments as it can be tailored to customer’s purchase intention and ultimately to drive sales. T...

e-Learning systems are increasingly being adopted by modern enterprises, because of their cost-down effect. However, the extant literature provides little insight into their beneficial consequences. It is expected that a transfer of acquired knowledge, skills and/or work attitudes to jobs will occur through elearning systems use. This makes e-learning systems a useful tool for improving job out...

Studies of organizational memory/ knowledge management, OM/KM, systems have found that using a common infrastructure to facilitate access to and utilization of knowledge and memory increases the usability and success of these systems. The solution to this is for organizations to have an integrated network. This paper discusses using the Internet as the integrated network. Several systems are de...

The main purpose of this paper is to evaluate a set of theory-grounded User Experience (UX)-related measures which are supposed to persuade course designers of particular UX-related problem areas based on a specific feedback format. Specifically, two online surveys on a university online course were conducted with the former focusing on the quantitative ratings and the latter on qualitative com...

Measuring information systems (IS) success has been and is of great interest to both researchers and practitioners. This article examines multidimensional approaches to measuring IS success and explores the current state of IS success research through a literature review and by classifying empirical articles that were published between 2003 and 2007. Based on a total of 41 academic journal and ...
