There are clearly two components involved in designing such a system, namely the concept of decision support systems (DSS) and the area of multicriteria decision making (MCDM). The multicriteria decision making environment as well as the definitions of the multicriteria decision making concepts used, are discussed in chapter 1. Chapter 2 gives a brief historical review on MCDM, highlighting the origins of some of the more well-known methods for solving MCDM problems. A detailed discussion of interactive decision making is also given. Chapter 3 is concerned with the DSS concept, including a historical review thereof, a framework for the design of a DSS, various development approaches as well as the components constituting a decision support system. In chapter 4, the possibility of integrating the two concepts, MCDM and DSS, are discussed. A detailed discussion of various methodologies for solving MCDM problems is given in chapter 5. Specific attention is given to identifying the methodologies to be implemented in the DSS. Chapter 6 can be seen as a theoretical description of the system developed, while Chapter 7 is concerned with the evaluation procedures used for testing the system. A final summary and concluding remarks are given in Chapter 8.

A dissertation submitted to the Faculty of Arts in partial fulfilment of the requirements for the Degree of Master of Arts (Clinical Psychology) in the Department of Psychology at the University Of Zululand, South Africa, 2013 / The study used a mixed methods methodology to investigate the factors that influence university students’ career decisions. This was motivated by the fact that students in disadvantaged communities are challenged by the negative socio-political conditions that resulted from the South African Apartheid system and these conditions limited the resources for people in disadvantaged communities. As more opportunities became available, it is vital that students entering tertiary education are equipped with the necessary skills and support to make informed career decisions. The sample consisted of 155 third year students from four faculties at the University of Zululand. Data was collected using a questionnaire. The data was analysed using a systematic approach. The results indicated that the factors influencing influence university students’ career decisions are the students’ educational background, home background, parental marital status parental occupation socio- economic status, the love for their careers, financial aid and high employment opportunities. The dissertation concludes that appropriate career education and guidance are essential for previously disadvantaged tertiary education students in order for them to maximize the opportunities available to them.

The basic problem of decision making is to choose the best alternative from a set of competing alternatives that are evaluated under conflicting criteria. In general, the process is to evaluate decision elements by quantifying the subjective judgments. The Analytic Hierarchy Process (AHP) provides us with a comprehensive framework for solving such problems. As pointed out by Saaty, AHP "enables us to cope with the intuitive, the rational, and the irrational, all at the same time, when we make multicriteria and multiactor decisions". Furthermore, in most organizations decisions are made collectively, regardless of whether the organization is public or private. It is sometimes difficult to achieve consensus among group members, or for all members of a group to meet. The purpose of this dissertation was two-fold: First, we developed a new aggregation method - Minimum Distance Method (MDM) - to support group decision process and to help the decision makers achieve consensus under the framework of AHP. Second, we evaluated the performance of aggregation methods by using accuracy and group disagreement criteria. The evaluations were performed through simulation and empirical tests. MDM • employs the general distance concept, which is very appealing to the compromise nature of a group decision making. • preserves all of the characteristics of the functional equations approach proposed by Aczel and Saaty. • is based on a goal programming model, which is easy to solve by using a commercial software such as LINDO. • provides the weighted membership capability for participants. • allows for sensitivity analysis to investigate the effect of importance levels of decision makers in the group. The conclusions include the following: • Simulation and empirical tests show that the two most important factors in the aggregation of pairwise comparison judgments are the probability distribution of error terms and the aggregation method. • Selection of the appropriate aggregation method can result in significant improvements in decision quality. • The MDM outperforms the other aggregation methods when the pairwise comparison judgments have large variances. • Some of the prioritization methods, such as EV[AA'], EV[A'A], arithmetic and geometric mean of EV[AA'] and EV[A'A], can be dropped from consideration due to their poor performance

This study is one of four exploratory studies concerned with coalitions of organizations that are formed to plan and develop social welfare programs within the local community. Although each study was conducted independently, taken together, their major purpose was to develop some insights and knowledge into the behavior of organizations and the ways in which they interact as they work together to develop community programs. They are then, exploratory studies of interorganizational behavior.

Sergiovanni (1994) believed that the rationale for shared decision making is that those who are closest to students are best equipped to make educational decisions to improve instructional programs. Liontos (1994) believed that change is most likely to be effective and lasting when those who implement it feel a sense of ownership and responsibility for the process. Building level administrators along with general and exceptional education teachers play a vital role in making educational practices a reality in schools (Kilgore, 2011). The administrator must have adequate knowledge of what the practices entail and how to mobilize staff so these educational practices are implemented effectively. In order to embrace the philosophy of inclusion, teachers must eliminate the focus on labels of students and make students with disabilities and support needs the determining factors in the provision of services and placement settings. This requires the school staff to shift paradigms when determining how best to meet the needs of students with disabilities. The overall purpose of this study was to determine whether or not general and exceptional education teachers working together had an impact on the inclusion process. These two groups of teachers collaborated to address challenges that students meet in the general educational setting. Their goal was to provide the best possible learning experience for students with disabilities in the least restrictive environment. While this study only took into account the challenges and successes of one school, in one school district, it is a glimpse of what other teachers, general and exceptional education are facing in inclusive settings. Results of the study showed that collaboration between general and exceptional education teachers clearly resulted in greater teacher efficacy. These teachers believed that they could make a positive difference. Teachers who exhibited this confidence were more likely to engage in collaboration. Some of the general education teachers who had the strongest desire for collaboration and worked closely with an exceptional education teacher exhibited a number of positive traits that led to more effective inclusion instruction. With this in mind, it is important for educational leaders to do all that they can to provide professional training and development to offer ideas and instances of collaboration to help the students with disabilities and teachers involved in educating them.

The process of making judgments and formulating convictions is a vital function performed by all human beings. Successful accomplishment of such tasks usually involves the integration of interoceptive cues (i.e. past experience, feeling states, etc.) with exteroceptive, or objective, information. Often, personal idiosyncracies determine the relative amount of flexibility with which convictions or opinions are held, regardless of contradictory information.
