Often entrepreneurial skills are overlooked and instead the focus is based on transferring generic skills in order for the youth to find employment. The Cape Flats suburb in the Western Cape is subject to economic strife and therefore it is imperative to include a platform to develop entrepreneurial thinking through the pursuance of dreams/goal setting when attempting to address youth development. The transfer of entrepreneurial skills in a township context is imperative to support local economic development strategies and policy making. The research design adopted a quantitative methodology approach employing a purposive sampling technique for data collection of individuals residing in the Cape Flats area. The piloting of the research instrument was statistically tested to ensure validity and rel...

Presentamos un software de procesamiento de información satelital que determina eventos de incendio, calcula perímetro y área de las zonas afectadas por cada evento, sentido y velocidad máxima de propagación, y duración del incendio, generando información para análisis estadísticos de incendios. Permite el análisis y representación gráfica de productos MODIS disponibles de algunos de los factores nombrados. Dentro del territorio continental americano de la República Argentina, el software está enfocado a reservas naturales, zonas forestales y rurales, donde los incendios son difíciles de controlar y también rutas cercanas a donde el incendio pueda propagarse.

O Organisational politics: visible and not so visible force 50 Management Today May 2006 Organisational politics exists as long as organisations themselves. It is inherent in all types of organisations. When we talk of organisational politics, we often use it very loosely and sometimes without a proper understanding as to how it manifests in organisations. The 21st century organisation, driven by a virtual organisation, internet and email has only helped to increase the complexity of the phenomenon of organisational politics. It is easy to blackmail employees, forwarding controversial e-mails in the organisation and across the traditional hierarchical boundaries. Yet many ..

To satisfy the approximate 5:6 ratio of the CoO and Ni lattice constants, we construct a supercell with 5 × 5 Co (O) and 6 × 6 Ni atoms per layer in the bulk regions. For the interface Ni layer and the adjacent Ni layer we consider different configurations and study the binding energy. We show for an ideal CoO interface terminated by 5 × 5 O atoms that the structure is more stable if there are 5 × 5 Ni atoms next to it instead of 6 × 6 as in the bulk. In addition, we observe that a transition layer with 31 or 33 Ni atoms located between the interface 5 × 5 Ni and bulk 6 × 6 Ni layers (which partially reflects the structures of both these layers) enhances the stability of the CoO/Ni interface. The electronic and magnetic modifications induced by the interface formation are discussed.

In order to select the superior solution, a new tool is introduced. Sourcing is one of the most critical issues in pharmaceutical industry. In addition, drug inventory shortages can cause irreparable humanitarian crises. However, only a limited number of studies has been focused on integrated sourcing and inventory policy of drugs so far. In real-world problems, it is difficult to calculate the exact cost of inventory shortage such as company reputation and humanitarian crises. To overcome this obstacle, in this study, the number of shortage is considered as a separate objective. Likewise, demands of the distributors and breakdowns of suppliers are stochastic, and due to the complicated nature of the problem is difficult to calculate the objective function by using classic methods. So, simulation is used for estimating the objectives of the problem. It's been proved that the problem of this study is NP-Hard. Therefore, a metaheuristic multi-objective particle swarm optimization (MOPSO) method is used to find the optimal solution. To test the reliability of the model and the proposed algorithm, a real drug distributing problem is used and after estimating a Pareto front, the best answer is chosen by The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method.
