Perceived external environment and individual decision making in schools. / CUHK electronic theses & dissertations collectionJanuary 2005 (has links)
Decision making is the essence of an administrator's job. While planning, organizing, staffing, directing, coordinating, reporting and budgeting are the basic traditional "functions" of management, each of these clearly involves decisions---decisions as to which plan to implement, what goals to pursue, and how best to achieve the desirable ends. / Empirical findings support the hypothesized relationship between perceived external environments by individual school administrators and the types of decision-making models they adopted in schools. In particular, the level of perceived constraint from the external environments' 'linguistic orientation' and 'resource policy' greatly influences the types of decision-making models chosen by individual administrators in schools. Furthermore, the pattern of adopting decision models in a perceived less-constrained environment (i.e., demography and resource policy) correlates with the pattern in a perceived highly constrained environment (i.e., social values, funding, and linguistic orientation), except for the environment of 'control'. This suggests that the decision-making experience gained from a less-constrained environment can serve as a reference frame for the highly constrained environment. Supplementary interview data support the validity of the self-reported decision-making questionnaire. / Given the fact that little is known about how issues arising from external constraint affect the administrative decision-making process, this study focuses specifically on their intricate relationships to broaden our understanding on the ever-expanding arena of administrative decision making in a turbulently growing working environment. / In the past, schools were instrumental in maintaining the existing social order, and as such, they were kept in status quo. However, the globalized reform movement has vastly reshaped schools' external environment, compelling the whole education system to undergo radical change as well. In this context, school administrators have to be more proactive to the changing environment to ensure the viability of their schools. / This research investigates the relationship between the perceived external environment by individual school administrators and the decision-making models they adopted in schools. This study adopts the construct of Lam (1985) which delineates the perceived external environment into four domains: political, economic, social, and cultural domains. Factor analysis on local data yielded six external variables, namely, demography, funding, linguistic orientation, social values, control, and resource policy, and these were perceived to exert varying degrees of constraint in the operation of schools. Issues arising from these external variables were identified. The conceptual rationale and procedures of resolving the issues constitute the basis of pinpointing the decision-making models that school administrators adopt. / Law Chan Fai. / "November 2005." / Adviser: Nicholas Sun Keung Pang. / Source: Dissertation Abstracts International, Volume: 67-11, Section: A, page: 4053. / Thesis (Ed.D.)--Chinese University of Hong Kong, 2005. / Includes bibliographical references (p. 200-217). / Electronic reproduction.

The role of context in spatial decision-making in GIScienceMount, Jerry 01 December 2013 (has links)
Context is an important driver in decision-making processes and problem-solving. It provides opportunities and constraints that must be considered when decisions are made. However, context is also difficult to define due to limits to knowledge and understanding of previous, current and future conditions. Context is dynamic, emergent, subjective and specific to individuals or groups at a particular place and time. However, context is often relegated to static representations of environmental properties with little consideration for the relationships between an actor (or actors), their task and the environments in which they are situated.
This research introduces a new perspective for context in spatial decision-making in Geographical Information Science (GIScience). In addition, this research contributes to GIScience by 1) introducing a theoretical definition of context, 2) the development of methods to bound context into relevant and non-relevent categories, 3) introducing graph-based context models to capture and store relevant context, and 4) demonstrating how context models can be used in spatial decision-support systems.

Asymmetric and imperfect knowledge: a proposal to replace unbounded rationality with bounded rationalityCao, Cung, Economics, Australian School of Business, UNSW January 2007 (has links)
The purpose of this thesis is to illustrate how the role of knowledge may be the missing link in economics and to argue that the assumption of unbounded rationality, which underpinned neoclassical economics, should be replaced by bounded rationality and that bounded rationality should be redefined as people are rational, but are constrained by asymmetric and imperfect knowledge. This decomposition of bounded rationality makes it possible for us to operationalize bounded rationality, which was founded by Herbert Simon in the 1950s, but has not been widely adopted in economics because the concept was considered too difficult to formalize. The inclusion of asymmetric and imperfect knowledge considerations in microeconomics provides new insights into the existence and boundaries of firms, the role and nature of institutions, financial market inefficiency and political choices. The inclusion of asymmetric knowledge considerations in macroeconomics can help explain the unequal distribution of wealth between individuals, firms and nations. A lack of knowledge, and the difficulties in overcoming a lack of knowledge, can help to explain aspects of economic fluctuations, prices rigidities, monetary non-neutrality and unemployment. Most importantly, when the role of knowledge is considered, it provides better explanations to various anomalies in economics, helps reconciles differences between various theories and may opens up the possibility of unifying various schools of economic thought.

The utilisation of quantitative information in groups' capital investment decisionsAng, Nicole Pamela, Accounting, Australian School of Business, UNSW January 2009 (has links)
One explanation for the increased use of interactive groups in organisations is that benefits are obtained from pooling individuals?? differing knowledge and abilities. However, prior experimental research has established that groups often do not discuss and use information effectively, exhibiting a bias toward information that is commonly known by all group members, rather than information that is unique to individual group members (common information bias). This dissertation investigated whether the provision of quantitative information resulted in improved group performance in two respects. First, it investigated whether quantitative information was discussed and used more than qualitative information. Second, it examined whether the quantification of information reduced the common information bias. This is important because a basic purpose of managerial accounting is to provide information that improves employees?? abilities to make optimal decisions. This dissertation utilised an experimental task known as a ??hidden profile?? to achieve the research objectives. In a hidden profile experiment, each group member receives some information that is common to everyone in the group, and some information that is unique to them. The group must discuss and use members?? unique information in order to uncover the optimal task solution. This dissertation examined the effect of information availability (common or unique) and information type (quantitative or qualitative) on information discussion and use. There were two stages to the experiment. First, individual group members had to make a capital investment decision, and write down their reasons for that decision. Second, groups had to discuss the information, come to a group decision, and write down their reasons for that decision. The results confirmed a common information bias at the group decision level, with groups significantly favouring common information over unique information, for all measures of discussion and information use. In contrast, while a preference for quantitative information was found at the individual decision level, at a group decision level there were no significant differences in the discussion or use of quantitative and qualitative information, with only one exception: significantly more statements were made about quantitative information.

The impact of cognitive biases on information searching and decision making.Lau, Annie Ying Shan, Centre for Health Informatics, Faculty of Medicine, UNSW January 2006 (has links)
This research is possibly the first study investigating the impact of cognitive biases on information searching and decision making. Set in the context of making health-related decisions, this research tests the hypotheses that (i) people experience cognitive biases during information searching; (ii) cognitive biases can be corrected during information searching; and (iii) correcting for biases during information searching improves decision making. Using a retrospective data analysis, a Bayesian model and a series of prospective empirical experiments, the cognitive biases investigated are anchoring effect, order effects, exposure effect and reinforcement effect. People may experience anchoring effect, exposure effect and order effects while searching for information. A person???s prior belief (anchoring effect) has a significant impact on decision outcome (P < 0.001). Documents accessed at different positions in a search journey (order effects) and documents processed for different lengths of time (exposure effect) have different degrees of influence on decision making (order: P = 0.026; exposure: P = 0.0081). To remedy the impact of cognitive biases, a series of interventions were designed and trialled to test for their ability to modify the impact of biases during search. A search engine interface was modified to allow for a document-level intervention, which attempts to debias order effects, exposure effect and reinforcement effect; a decision-focussed intervention for debiasing the anchoring effect; and an education-based intervention to inform users about the biases investigated in this research. Evaluation of these alterations to the search interface showed that some of the interventions can reduce or exacerbate cognitive biases during search. Order effects are no longer apparent amongst subjects using a keep document tool (i.e. order debiasing intervention) (P = 0.34); however, it is not associated with any significant improvement in decision accuracy (P = 0.23). Although the anchoring effect remains robust amongst subjects using a for/against document tool (i.e. anchor debiasing intervention) (P < 0.001), the intervention is marginally associated with a 10.3% increased proportion of subjects who answered incorrectly pre-search to answer correctly post-search (P = 0.10). Overall, this research concludes with evidence that using a debiasing intervention can alter search behaviour and influence the accuracy and confidence in decision making.

Strategic economic integration.Teo, Ernie G. S., Economics, Australian School of Business, UNSW January 2007 (has links)
The French and Dutch refusal to ratify the European Constitution in 2005 and the collapse of many East German businesses post-reunification; are just some examples of the hurdles integrating nations face. Integration of nations affects many economic factors such as public good allocation, trade, production, labour, consumption and even macro-economic policy instruments. Therefore, it is important to understand what motivates integration. Few scholars have broached the subject of the integration of nations (see Goyal and Staal (2004)), where size asymmetry and historical dependence are considered. Starting with Alesina and Spolaore (2003)'s Size of Nations symmetric framework, we attempt to do this with a two nation (asymmetric in size) location model. The key findings are that size differentials and the constitutional design (the identity of the decision maker) matters. In this thesis, we consider the social planner (government) and voters. The social planner maximizes social welfare for his own nation. Voting outcomes become non-trivial as it depends on the number of alternatives and the voting system. We categorize integration into two main forms. Full Integration is when the two nations fully integrate to form a new one, only one capital remains. Federated Integration is where the nations integrate but retain some form of sovereignty; this is represented by the retention of both capitals. Size difference matters when two nations chose to integrate. As the size difference between the two nations increase it becomes harder for integration to occur; nations would integrate if there is no size difference. The identity of the decision maker will affect the threshold on size.
