Tillage erosion is the dominant soil erosion process in hummocky landscapes. The topsoil lost from the convex upper slope positions (i.e., hilltops knolls, ridges) gradually makes its way to the concave lower slope positions (i.e., foot slopes, toe slopes/depressions), while reducing yield capability in the knolls. The accumulation of topsoil in the concave lower slope positions does not increase yield potential. Landscape restoration is a process by which organic-rich topsoil is removed from lower slope positions and is moved to the knoll positions where it is applied and incorporated as additional topsoil. Field studies on this matter have shown increases in crop yield productivity due to land restoration on the convex upper slope positions. Using a model developed in STELLA ®, this research examines the net monetary benefit of landscape restoration in specific landscape scenarios modeled after areas in Manitoba which are prone to tillage erosion. This study demonstrates that farming operations in hummocky landscapes, experiencing topsoil loss at knolls benefit from landscape restoration as it can lead to positive net returns. In this study, the research shows that landscape restoration, in the Rural Municipality of Lorne (South Western Manitoba), led to revenues greater than restoration costs for arable land used for agricultural purposes. Depending on soil conditions and tillage choices the payback period for landscape restoration ranged from 8 to 18 years.

Varje år ökar antalet äldre personer och i samband med den ökningen blir även antalet äldre personer med körkort allt fler. Med åldern är det vanligt att reaktionsförmåga, syn och hörsel försämras vilka alla är viktiga egenskaper för trafiksäkerheten. Läkare i Sverige är skyldiga att rapportera till Transportstyrelsen om en individ inte anses vara lämplig att köra bil. Att läkare över huvud taget tar upp körkortsfrågan med sina patienter sker endast i 60 procent av fallen och därmed fortsätter många olämpliga körkortsinnehavare att köra bil. Majoriteten av länder inom Europeiska Unionen (EU) har någon form av övre åldersbegränsning i körkorten där körkortsinnehavarna måste genomgå en kontroll för att få körkortet förnyat. Det är endast Sverige och sex andra länder inom EU som inte har någon form av körkortskontroll för äldre och i denna studie kommer en kostnadsnyttoanalys utformas för att ta reda på om kontroller för körkortsinnehavare över 75 år skulle reducera antalet döda och skadade i trafikolyckor och därmed vara samhällsekonomiskt lönsamt. De länder som tillämpar körkortskontroller har olika bestämmelser hur metoderna är utformade och studien tar upp hur det fungerar i några av länderna. Vidare redovisas forskning inom området och resultatet av undersökningar av olika testmetoder. Merparten av forskningsresultaten visar att körkortskontroller inte har någon större effekt på trafiksäkerheten och det går inte med säkerhet att säga hur många liv som räddas och antal skadade som skulle kunna reduceras genom införandet av tester. Därmed har dessa siffror fått antagits utan att ha något säkert underlag och utifrån denna antagning visar kostnadsnyttoanalysen att införandet av körkortskontroller inte skulle generera välfärd i Sverige. Utifrån resultatet går det att dra slutsatsen att Sverige har gjort en god bedömning om att endast ha anmälningsplikt för läkare förutsatt att den följs bättre. Även om resultatet visar att kontroller för personer över 75 år inte ska införas bör ändå trafiksäkerheten för äldre utvecklas genom att till exempel förenkla körningen vid vänstersvängar och förbättra kollektivtrafiken. / The numbers of elderly increase every year and the amount of older people with a license will increase as well. When getting older, it is natural that the reaction time, hearing and vision will change and these are all important features for traffic safety. Doctors in Sweden are required to report to the Swedish Transport Agency if an individual does not seem appropriate to drive. It is not common that doctors ask their patients about their physical health and ability to drive, the questions are only asked in about 60 percent of the physical evaluations and because of that, inappropriate license holders may proceed to use a vehicle. The majority of countries within the European Union embrace some kind of upper age limit to provide drivers with a valid license and several countries have compulsory medical examinations for license holders at a certain age. It is only Sweden together with six other EU countries that does not provide any license controls for elderly and in this study a cost benefit analysis is designed to determine whether controls for drivers over the age of 75 would reduce deaths and injuries caused by traffic accidents and thus increase welfare. The countries that apply driving license controls have different rules how the controls are designed and the study presents how it works in some of the countries. Further, research within the area shows that license controls does not have any sufficient effect on traffic safety. It cannot with certainty be said how many lives are saved and the amount injuries that could be reduced by an introduction of these tests. Thus, these numbers are adopted without any sufficient evidence and from this an assumption of the cost benefit analysis will show that an introduction of license controls would not generate a welfare increase in Sweden. Based on the result it is possible to conclude that Sweden has made a good assessment to have only a reporting requirement for physicians but the reports must be stricter. Although the result shows that license controls for people over the age of 75 should not be imposed, nevertheless traffic safety for elderly should be further developed, for example with simplifying left turns and improve public transportation.

The South African pharmaceutical market is seen as part of the so called "pharmerging" markets, together with countries like India, China and Brazil. These "pharmerging" markets are the fastest growing markets within the global pharmaceutical industry. The distribution of chronic medicine in South Africa is a growing market, as the disease burden in South Africa continues to escalate, with the incidence of chronic conditions growing at a rapid rate. The study will focus on one of South Africa’s pioneer courier medication service providers, with more than twenty years’ experience in the healthcare industry. The company will be referred to as Pharmacy X. The mission of Pharmacy X is to provide the right chronic medication, to the right patient, at the right place, at the right time. It is imperative to ensure that a patient receives his/her chronic medication on the scheduled date of delivery to ensure compliance and customer satisfaction. To achieve a competitive advantage, companies increasingly depend on their supply chain partners to minimize cost and improve business processes. The core value chain activity of outbound logistics has been outsourced by Pharmacy X to several courier companies. This study will aim to understand the importance of the outbound logistics function within the value chain of the company and the costs involved with the outsourcing of the function. The primary objective of this study was to determine the feasibility of an in-house courier operation in the Bloemfontein area versus the current outsourced courier model. In order to achieve the primary objective of the study, several secondary objectives were set and reached throughout the four chapters of this study. The study applied cost benefit analysis techniques to determine the feasibility of the Bloemfontein courier investment project. All the cost benefit analysis techniques concluded that the Bloemfontein courier investment will be a financial viable operation. The Bloemfontein courier investment will increase shareholder value over the period of the project compared to the current outsourced model. The contribution of this case study to determine the feasibility of a courier operation investment can be of value to Pharmacy X. The current projected total courier cost of Pharmacy X for the 2013 financial year amounts to more than a third of the total operational cost. The findings within the case study can lead to a greater national roll out of courier operations in order to reduce costs and increase profit margins for Pharmacy X. / MBA, North-West University, Potchefstroom Campus, 2014

Usability testing is a branch of usability engineering that focuses on analyzing and improving user interactions with computer systems. This testing technique has been used in different industries for years and has proven to be very useful in determining major issues with applications before they are released, however the use of this technique has been slow to gain widespread acceptance in testing health information systems. This study was designed to determine if a specific form of usability testing, Low-Cost Rapid Usability Testing, can be introduced as a standard part of the system development lifecycle (SDLC) for health information systems in a cost effective manner. To determine if this was possible a full cost-benefit analysis of Low-Cost Rapid Usability Testing was performed on a health information system, the BC Chronic Disease Management (CDM) Toolkit, tracking all of the costs involved in the testing process and comparing them against the possible costs that may have been incurred if this testing was not performed. It was found that by introducing this technique into the system development lifecycle to allow for earlier detection of errors in a health information system it is possible to achieve an estimated 36.5% to 78.5% cost saving compared to the impact of errors going undetected and causing a technology-induced error. Overall it was found that Low-Cost Rapid Usability Testing can be implemented in conjunction with other testing techniques in a cost effective manner to develop health information systems, and computer systems in general, which will have a lower incidence of technology-induced errors. / Graduate
