Stephen Hawking stated in A Brief History of Time (1988) that “a good theory is characterized by the fact that it makes a number of predictions that could in principle be disproved or falsified by observation.” In other words, a good theory needs to predict things that can be tested. As we already discussed in this module, the results of those tests will in turn lead to more questions and more tests.
Based on the video with Stephen Hawking in this week’s module, answer the following questions.
Comment on what you think drives a scientist like Stephen Hawking to ask, “Why?”
How has Hawking’s research contributed to the field of natural science?
When you consider the work of natural scientists in general, how do you think developments in scientific thinking end up influencing how scientific study is carried out? Provide an example.
You will answer some similar questions as part of Project 3. It is recommended that, in addition to responding to the questions, you keep a record of your response to these questions for use in Project 3, which is due at the end of Module Eight.
behaviour of the situation the consequence is maximum group performance and satisfaction. However, if the group are not performing and achieving goals or are not satisfied or both, then the leader is able to amend their actual behaviour to improve this. Leaders able to monitor performance and satisfaction, and understand what is required to amend the situation will achieve optimum group performance in Chelladurai’s model.
The one limitation of Chealldurai’s model is that it assumes the leader is in a position of complete positional power over the group, and can implement any leadership style of their choosing without constraints. Positional power is the authority and influence a leader has over a group, if the leader has positional power, they will be able to implement the leadership style they best see fit for the situation. Positional power cannot be measured or quantified, making it highly ambiguous and hard for a leader to understand whether they have it or how then can gain it. It becomes the responsibility of the organisation to have policies in place to provide leaders with some positional power, usually by establishing a clear hierarchal structure. By establishing a hierarchy, the leader is perceived by the group to be able to make demands and expect compliance from them giving the leader legitimate power (French and Raven, 1959). Secondly, by providing the leader with the ability to reward compliance and punish non compliance from the group, the leader has reward and coercive power (French and Raven, 1959). To obtain complete power over the group the leader must gain the trust and belief of the group that they are capable of success, by ensuring the group are both satisfied and meeting performance goals.
The importance of establishing a hierarchy became evident during the planning stage of the outdoor management course for the red team, the coordinators within the team assumed leadership roles but were unable to gain positional power due to the team being a peer group (Pettinger, 2007). The leaders selected had little authority and influence over the group as everyone was perceived to have the same rank, status and occupation, hence the leaders had none of French and Ravens five bases of power (Pettinger, 2007). The result was leaders with no positional power over the group, so could not direct the group with the method of leadership required for the situation. The task had significant constraints, particularly a short time frame and a large group size, for this situation Chelladurai recommends an autocratic
