The sensitivity of vector borne diseases like malaria to climate continues to raise considerable concern over the implications of climate change on future disease dynamics. The problem of malaria vectors shifting from their traditional locations to invade new zones is of important concern. A mathematical model incorporating rainfall and temperature is constructed to study the transmission dynam...

This paper calls for the need to address climate change within the concept of sustainable development, in recognition of the interrelationships between environmental, economic and social systems. So far, health- providing organizations such as hospitals have paid surprisingly little attention to the relationships between environmental change (e.g. climate change) and human health, or between ho...

The widespread introduction of technology to support learning and teaching has put pressure on the UK educational community to consider its ability to support and manage online learning. The Joint Information Systems committee (JISC) has recently invested £5 million in working with further education colleges and universities to implement and research Managed Learning Environments as a key conce...

pierre-gerlier forest and his colleagues make a strong argument for the need to expand policy capacity among healthcare actors. in this commentary, i develop an additional argument in support of forest et al view. forest et al rightly point to the need to have embedded policy experts to successfully translate healthcare reform policy into healthcare change. translation of externally generated i...

Technological change is examined in a model of capital production to show that “creative destruction” can occur as an outcome of firm’s optimizing behavior. Capital systems are made up of components that are necessary for them to operate and that have uncertainty with respect to durability. For each type of technological change agents make a corresponding decision about whether to continue to u...

Compassion shown towards victims often decreases as the number of individuals in need of aid increases, identifiability of the victims decreases, and the proportion of victims helped shrinks. Such “compassion fade” may hamper individual-level and collective responses to pressing large-scale crises. To date, research on compassion fade has focused on humanitarian challenges; thus, it remains unk...

The Tibetan Plateau is regarded as one of the most climatic-sensitive regions all over the world. Long-term remote sensing data enable us to monitor spatial-temporal change in this area. The vegetation changes of the western Nyainqentanglha region were detected by using RS and GIS techniques. And the vegetation coverage was derived by the NDVI-SMA (spectral mixture analysis) methods. An incense...

Currently, the development of the visual design of Web Information Systems is mainly based on developers’ experiences. Late considerations of graphical issues during the development of WISs often result in visually inflexible solutions and cause problems for extension and change management. This article discusses screenography, attempts to systematise WIS layout and thus to complement existing ...

During 1999 a medium sized City Council was faced with major challenges as a result of its Long Term Financial Strategy (LTFS). Initial work indicated that if the required developments, primarily in terms of infrastructure requirements, were to be met then the Council was going to be faced with unacceptable rises in debt and rates. As a result a major project was initiated which had as its majo...
