Information security education and training needs to be valued and assessed from various perspectives. This study presents two differing viewpoints from which such an evaluation can be perceived – those of the individual and the organisation. Some sorts of profits are sought after by each of the two, although this is expressed and hence valued differently depending on the perspective taken. We ...

A large share of the poor in developing countries run small enterprises, often earning low incomes. This paper explores whether the poor performance of businesses can be explained by a lack of basic business skills. We randomized the offer of a free, 48-hour business skills course to female entrepreneurs in rural Mexico. We find that those assigned to treatment earn higher profits, have larger ...

This article develops a Sustainability Informatics Framework, a framework that connects Information Technology with sustainability and is based on the Belief-Action-Outcome and Energy Informatics frameworks. The triple-bottom line (People, Planet, and Profit) is adopted as a criterion for measuring sustainability and three sustainability indices are first formulated and then visualized using Su...

This paper shows that two societies differing because of the people’s initial propensity to devote time and efforts to non-profit activities may never converge. This lack of convergence is interpreted as the tendency of the cultural values and attitudes dominant in each society to perpetuate because of the economic behavior and the social processes that they contribute to elicit. Furthermore, i...

Desertification refers to land degradation phenomenon in arid, semi-arid and dry sub-humid areas, resulting from various factors including climate variation and human activities. For evaluation and mapping of desertification many research have been conducted leading to regional and local models. In this research, among different existing methods IMDPA‌ was selected and desertification intensity...

Information and adequate data on intensity–duration–frequency of rainfall are regularly required for a variation hydrologic, environmental hydraulic applications. This paper presents intensity-duration-frequency equations Makurdi, Nigeria. Rainfall intensities from Makurdi were used to establish empirically derived constants about thirteen different equations. These evaluated statistically usin...

The authors’ scientific approach highlights the method to allocate resources for investments to modernize two laboratories within a school, using linear programming. The study aims to achieve maximum profit by upgrading the two laboratories. We made recommendations with respect to the optimum solution. However, using optimization conception is only possible if the conditions for achieving the r...

In this paper we present an unsupervised algorithm to select the most adequate grouping of regions in an image using a hierarchical clustering scheme. Then, we introduce an optimisation approach for the whole process. The grouping method presented is based on the maximisation of a measure that represents the perceptual decision. The whole strategy takes profit from a hierarchical clustering to ...

The volume of stored data increases rapidly. Therefore, the battery of extracted association heavily prohibits the better support of the decision maker. In this context, backboned on the Formal Concept Analysis, we propose to extend the notion of Formal Concept through the generalization of the notion of itemset aiming to consider the itemset as an intent, its support as the cardinality of the ...

The transmission of multimedia streams with a particular and guaranteed level of QoS (Quality of Service) from source to destination is a major challenge in multimedia communications over IP networks. In this paper, we introduce a generalized, flexible form of the traditional SLA (Service Level Agreement) between users and network owners, for the transmission of a multimedia stream with several...
