A Logical Investigation on Global Reading of Diagrams (Technical Note)

Abstract In graphical or diagrammatic representations, not only a basic component of a diagram, but also a collection of multiple components can form a semantic unit, and it often helps reasoning with that diagram. For example, a row and a column in a table, or transitively closed nodes in a directed graph can be regarded as a semantic unit on its own. Designers have long noticed the importance of information conveyed by these global object

Ontology-Based Data Access and Integration

An ontology-based data integration (OBDI) system is an information management system consisting of three components: an ontology, a set of data sources, and the mapping between the two. The ontology is a conceptual, formal description of the domain of interest to a given organization (or a community of users), expressed in terms of relevant concepts, attributes of concepts, relationships between concepts, and logical assertions characterizing the domain knowledge. The data sources are the repositories accessible by the organization where data concerning the domain are stored. In the general case, such repositories are numerous, heterogeneous, each one managed and maintained independently from the others. The mapping is a precise specification of the correspondence between the data contained in the data sources and the elements of the ontology. The main purpose of an OBDI system is to allow information consumers to query the data using the elements in the ontology as predicates. In the special case where the organization manages a single data source, the term ontology-based data access (ODBA) system is used

The Double Paradox of Elementary Economics Education

Elementary economics textbooks have become less attractive to students requiring only an introduction to economics, given that their content is pervaded by mathematical diagrams and simple equations. Also they are of relatively little value to those interested in, for example, attempting to gain an understanding of the New Economy, for they rarely emphasise business innovation and its crucial dynamic role. These factors engender something of a double paradox. First (paradox of the tools and the audience), newcomers are frequently 'turned off' by existing economics textbooks due to the pervasive use of mathematics. Second (paradox of the content and relevance), those newcomers who are not initially turned off tend to be disenchanted with economics because they perceive that economics is of little use in understanding the New Economy in which they work, or will come to work. We suggest an integrated solution to both paradoxes. The implementation entails a minor reorientation of the traditional pedagogical strategy for teaching introductory economics.Double paradox, elementary economics education

Factors that contribute to obesity problem among UTHM catering student

Negative perception by the society and the hospitality industry toward the disabled people is very high and it has to be changed and this parties should be given opportunity to work in this industry. Rosli, et al (2011) states the acceptance in the small and medium industries towards the disabled is at moderate level. However, in 2005, Ministry of Higher Education Malaysia (KPTM) has initiated Polytechnic Ibrahim Sultan, Johor Bahru conduct a pioneer program to produce graduates with disabilities (OKU) with hearing impairments for a career in the hotel industry. Related to the situation, some lecturers were sent to attend sign language courses for the preparation for the program, some facilities were updated to fit their needs. To this present Polytechnic Ibrahim Sultan, Johor Bahru has produced hundreds of OKU graduates. It is hope that the graduates produced from this program could reduce the number of foreign worker working in the industry. Dependence on foreign workers should be reduced because there are almost 2.6 million people with special needs in Malaysia. Some of them have been able to pursue their studies to diploma and Bachelor degrees. Through the development of education they are participated in, it is hoped that they will also contribute to the country's economy. The Government of Malaysia is in the effort to transform employers' perceptions towards this group to be more positive. Thus, several initiatives or benefits had been made by the Government of Malaysia to attract more government link companies (GLC) and private firms to hire people from this group. However there are also some challenges and obstacles faced by the industry in accepting these graduates at their company. Taheing (1996) states that in its study it has been able to identify problems that limit the employment of disabled persons including physiological factors, disability due to defects, occupational types, gender factors, workplace environment, personality, illness and other disabilities. This is a challenge and obstacle faced by the employer in hiring the disabled graduates in their industry. Therefore, the industry is highly concerned with the selection of highly capable employees in helping to increase profits to the company

A practitioner's guide to 'Imagine', the systemic and prospective sustainability analysis

The purpose of the Mediterranean Action Plans Coastal Area Management Programme is to help Mediterranean countries implement a sustainable management process for their coastal areas. This in particular implies thinking collectively about possible futures by taking into account past developments and the present situation of the area in question. To do so and right from the very start, the Blue Plan has assisted teams involved in the CAMPs to use the systemic and prospective approach so as to highlight priorities, forecast negative developments and suggest action to be taken to establish sustainable development in the Mediterranean's coastal areas. What do we mean by sustainable development? The Blue Plan adheres to a definition that is a blend of what you find in the Bruntland Report and at the FAO, 'sustainable development is one that respects the environment, is technically appropriate, economically viable and socially acceptable, making it possible to meet the needs of present generations without jeopardising the ability of future generations to meet their own needs'. In this framework the 'Imagine' analysis of systemic and prospective sustainability now proposes a set of tools and methods (a methodological corpus) to describe, assess and examine the level of sustainability of an eco-socio system in the past, present and future by means of indicators and a participatory process that considers local actors to be experts at their level
