Semantic Interoperability in the d-learning in the era of Cloud Computing: Simplicity or Complexity Introduction During recent years there has been an expansion of information system covering the same domain. These systems need more and more to communicate‚ collaborate and exchange content with each other to achieve common goals. Many domains know this revolution‚ including the learning. Learning systems have a rich and varied content must be accessible‚ sharable‚ and exchangeable while keeping

homogeneity across cultures. The theory of relative face orientation We have discussed that Brown and Levinson’s (1987) face-saving politeness theory has been undermined for its inability to be applied universally. In surveying recent studies in cross-cultural communication‚ Mao (1994) mentions Janney and Arndt (1993)‚ who characterise it as idealistic‚ culturally biased‚ and lacking objective empirical evidence for the evaluation of their politeness universals. Instead of a theory centered on universals

The interaction between biological systems creates complexity because of the vast interactions in species. There are predator prey relationships that rely on a balance between the two. If there is too many of one and not enough of another there is an imbalance that throws off the food chain. The imbalance of the food chain affects all the organisms in that community. There are many communities where humans are the cause in the imbalance and the food chain flips. Primary consumers over power tertiary

In today’s society work is most likely to be associated with paid work. We always tell people about our paid employment‚ the work where we receive a regular income.

For example those in upper class enjoy greater life chances than those in working class

Notes The ultimate goal of theory evaluation is to determine the potential of the theory to scientific knowledge. Hardy • Theory evaluation: o meaningful and logical adequacy o Operational and empirical adequacy o Testability o Generality o Contribution to understanding o Predictability o Pragmatic adequacy Logical adequacy (diagramming) - identifying all theoretical terms (concepts‚ constructs‚ operational definitions‚ referents).

During 1950 and 1960‚ some small group decision making developed the idea of contingency theory. At the end of 1950s‚ academic schools began to utilize the contingency idea into organization theory. The term “contingency theory was created‚ it challenged the traditional management notion: finding the one best way to organize. Together with special and united notion of subsystems‚ the contingency theory drew theorists’ attention and obtain acceptance. Then more and more researchers took part in studying
