Asymmetric Release Planning-Compromising Satisfaction against Dissatisfaction

Maximizing satisfaction from offering features as part of the upcoming release(s) is different from minimizing dissatisfaction gained from not offering features. This asymmetric behavior has never been utilized for product release planning. We study Asymmetric Release Planning (ARP) by accommodating asymmetric feature evaluation. We formulated and solved ARP as a bi-criteria optimization problem. In its essence, it is the search for optimized trade-offs between maximum stakeholder satisfaction and minimum dissatisfaction. Different techniques including a continuous variant of Kano analysis are available to predict the impact on satisfaction and dissatisfaction with a product release from offering or not offering a feature. As a proof of concept, we validated the proposed solution approach called Satisfaction-Dissatisfaction Optimizer (SDO) via a real-world case study project. From running three replications with varying effort capacities, we demonstrate that SDO generates optimized trade-off solutions being (i) of a different value profile and different structure, (ii) superior to the application of random search and heuristics in terms of quality and completeness, and (iii) superior to the usage of manually generated solutions generated from managers of the case study company. A survey with 20 stakeholders evaluated the applicability and usefulness of the generated results

Complications in Esthetic Surgery

Facial plastic and reconstructive surgery is a remarkably diverse specialty, ranging from maxillofacial trauma and reconstruction to facial rejuvenation, rhinoplasty, cleft surgery, microvascular surgery, facial cosmetic procedures, and pain control. It is unique among surgical specialties due to changing trends, racial, and regional ethnic preferences that influence what is considered an esthetic result

Reforming decentralized integrated health care systems: Theory and the case of the Norwegian reform

In this essay a conceptual and theoretical scheme for decentralized integrated health care systems of the northern European kind is developed. With small changes it is also applicable to other countries, e.g. Italy, Spain, and Portugal. Three ideas tie together the scheme: modified fiscal federalism, principalagent thinking and the analysis of discrete structural alternatives from new institutional economics. As a special case it encompasses the ideas of planned markets and public competition developed by von Otter and Saltman. The scheme can be used to analyse driving forces behind reforms and prediction of effects. To illustrate the thinking the recent Norwegian reform is put into context, not only geographically but also theoretically. The geographical context is that of Scandinavia and there is a summary of reforms in the Scandinavian countries over the past 20-30 years. The essay thus serves the double purpose of presenting and evaluating the Norwegian reform in a Scandinavian context and to take part in the neglected discipline of developing a theory of health care reform. The Norwegian January 2002 reform is described in some detail. It is a reversal of the Scandinavian model of decentralization and a move towards more centralism. The hospital system was transferred to the state that established five regions with independent (non-political) boards and each region has a number of daughters (hospitals) that have great autonomy with their own boards and are outside the legal restrictions of the public sector. Basically the idea is to mimic the corporate structure of large private companies. The reform is evaluated based on principal-agent thinking and the analysis of discrete structural alternatives. Overall there is no a priori reason to expect large improvements in efficiency – but on the other hand neither should one expect things to get worse. Many effects depend, however, crucially, on (a) the financing system that will be put in place late 2002 or early 2003, and (b) whether or not the political and management culture change as a result of the reform. In the concluding sections possible implications for Denmark and Sweden are discussed.Health care reform; Norway; principal-agents; discrete structural analysis

The influence of the mandate system and the political ideological persuasion on the performance of South Africa's real estate industry

Submitted in accordance with the requirements for the Degree of PhD (Marketing) at the University of the Witwatersrand September 2016Purpose: The impact of the mandate type used and real estate agents’ ideological outlook on conflict of interests and compromising of principals’ interests together with their effect on the ultimate outcomes has largely been ignored in the South African real estate industry. The purpose of this study was to investigate the effects of dual mandate system and ideology on the outcomes to buyers and sellers of properties. This was achieved by investigating their influence on the conflict of interests and compromising the interests of the principals and how these in turn lead to suboptimal outcomes for the industry. Method: Stratified random sampling was used for information gathering. Data were collected using face-to-face filling in of the survey instrument and 204 participants agreed to take part in the study. Confirmatory factor analysis (CFA) was employed to assess the reliability and validity of the results. Findings: The results reveal that the dual mandate system and ideological persuasion of actors in the real estate industry does positively impact on conflict of interests and also compromises the interests of the principals. Conflict of interests and compromising principals interests have also been found to negatively affect the resultant outcomes for the principals. Practical implications: The dual mandate system should be reconsidered with the view of revising or changing it altogether. Also, practices of real estate agents should be closely monitored by relevant authorities to ensure that they do not disadvantage other consumers. Insights gained from this study provide the basis for future policy-making by government and for academic activity on training of new real estate agents. The findings of this study are expected to assist the Estate Agency Affairs Board (EAAB) as the custodians of licensing of real estate agents. Research limitations: The participants were all from Gauteng Province which might limit generalizability prospects to other provinces. Also, some respondents might have given biased responses by attempting to prove that they were not ignorant of how the industry operates. Key concepts: Dual mandate system, Ideological outlook, Conflict of interests, compromising of principals and Outcomes.MT201
