3.1.1 Global convergence? The Nobel Laureate, Douglass North (1990, p. 46), has argued that progress, from a less to a more complex society, is characterised by a lengthy and uneven but unidirectional move from informal institutional rules of practice to formal constraints. Thus, informal sanctions, taboos, customs, traditions and codes of conduct are superseded by formal rules embodied in constitutions, laws and legally enforceable property rights, including intellectual property and copyrights. North argues that the
2.4 Glocalisation ‘Glocalisation’ combines the words ‘globalisation’ and ‘localisation’ to emphasise the idea that a global product or service is more likely to succeed if it is adapted to the specific requirements of local practices and cultural expectations. The term started to appear in academic circles in the late 1980s, when Japanese economists used it in articles published by the Harvard Business Review. For the sociologist Roland Robertson, who is often credited with po
5 Summary In this unit we have focused on effective management of the routine activities of a project. I began by considering what a manager can do to ensure that tasks and activities start on time. You should now be able to take the steps that are required to implement a project. Appropriate people need to be appointed to teams and to be clear about individual and group responsibilities. The accommodation and equipment must be secured, together with ensuring that the necessary resources are in place t

Construct And Test Roofs for Different Climates
We design and create objects to make our lives easier and more comfortable. The houses in which we live are an excellent example of this. Depending on your local climate, the features of your house will be different to satisfy your particular needs; protection from hot, cold, windy, and/or rainy weather. Students should be aware of the different types of roofs found on various houses in different environments throughout the world. This can be done with books and photos. Models of the houses will
Yeast Cells Respire, Too (But Not Like Me and You)
Students set up a simple way to indirectly observe and quantify the amount of respiration occurring in yeast-molasses cultures. Each student adds a small amount of baking yeast to a test tube filled with diluted molasses. A second, smaller test tube is then placed upside-down inside the solution. As the yeast cells respire, the carbon dioxide they produce is trapped inside the inverted test tube, producing a growing bubble of gas that is easily observed and measured. Students are presented with
