An Empirical Investigation of Food Consumer Behaviour in an Emerging Market
Full text linkThis study examines food consumers in the capital of Romania. A study of 485 consumers using the Theory of Reasoned Action underpinned the investigation of
determinants of food choice. Drawing on a Structural Equation Models approach, causal paths for six commodities are estimated. Attitudes and habits tend to be significant predictors of intention to consume food. Intention is a significant, yet modest, predictor of actual behaviour. Although attitudes tend to be a key predictor in TRA, the higher paths for attitudes relative to habit contrast the study of Saba and Di Natale (1999). As reported elsewhere (Bagozzi and Warshaw 1990) the predictive power of the models in explaining behavioural intent exceeds the corresponding one for behaviour. The results of this empirical study support the notion that attitudes and habits influence behavioral intentions of food consumers in this emerging market. Competing structural models are discussed and the implications of the study for both food marketers and health campaigners are highlighted
Knowledge based system development as an engineering process
No full textThis thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Knowledge Based System (KBS) development is a difficult and challenging task, in particular in knowledge intensive domains. The traditional view of knowledge engineering is one of mining experts' knowledge and somehow transforming it into a machine usable form. This process, in general, suffers from insufficient or misconstrued representation of experts' problem solving behaviour. It is also unstructured and unduly biased at an early stage by design and implementation issues - normally in the form of incremental prototyping.
We believe that both knowledge acquisition and KBS development for real life applications will require a 'structured' approach. This approach should harness a KBS developer's ability in extracting knowledge and developing systems. The structure should also be sufficiently flexible to allow the knowledge engineer to use his sense of creativity in developing a KBS. This thesis puts forward such a structured approach, in which KBS development is carried out in an engineering fashion. A process in which the worker is provided with an environment for developing knowledge based systems as an engineering process, as opposed to that of an artform or crafting.
The main emphasis of this work is that part of the process which deals with the analysis and design phases in developing KBS. The analysis is performed at an 'epistemological' level, not coloured by design or implementation issues. The output of this phase captures both an expert's problem solving capability, and the business constraints placed upon the intended system. This is then used by the design process in order to create an optimal, workable, and elegant design architecture for the ultimate system.Commission for the European Communities'

A tool-supported approach to inter-tabular verification.
Full text linkThe use of decision tables to verify KBS has been advocated several times in the V&V literature. However, one of the main drawbacks of those system is that they fail to detect anomalies which occur over rule chains. In a decision table based context this means that anomalies which occur due to interactions between tables are neglected. These anomalies are called inter-tabular anomalies. In this paper we investigate an approach that deals with inter-tabular anomalies. One of the prerequisites for the approach was that it could be used by the knowledge engineer during the development of the KBS. This requires that the anomaly check can be performed on-line. As a result, the approach partly uses heuristics where exhaustive checks would be too inefficient. All detection facilities that will be described, have been implemented in a table-based development tool called PROLOGA. The use of this tool will be briefly illustrated. In addition, some experiences in verifying large knowledge bases are discussed.

KBS Demonstration
Full text linkThe Knowledge Based System (KBS) demonstration included five different items: the executive program, three of the industrial codes, and graphical display capability using current MYI MS-DOS programs. The graphics capability included two and three dimensional plots viewed from different angles. This capability will be ported to OS/2 and made an integral part of the KBS executive program. The three codes demonstrated included Spiral Groove Gas Seals (SPIRAL), Gas Cylindrical Seals (GCYL), and Incompressible Seals (ICYL). The SPIRAL and GCYL interface has the standard PM interface, while the ICYL interface was designed using ToolBook
Peta Hijau Hubungannya Dengan KBS Sebagai Wisata Edukasi Alam Berkelanjutan
Full text linkPerkembangan kebun binatang sebagai tempat hiburan merupakan sebuah fenomena yang sangat menarik untuk diperhatikan. Kebun Binatang Surabaya (KBS) adalah sebuah tempat wisata kebanggan kota Surabaya. Keberadaan KBS ini sudah sejak tahun 1970, yang terbesar di Asia Tenggara. Nyaris keberadaan KBS kurang disadari oleh warga kota SUrabaya, karena kondisi fisik yang ada didalamnya, tidak terawat. Potensi KBS yang ada saat ini dapat menjadi evaluasi untuk dapat ditingkatkan kualitasnya menjadi bagian pembentuk ruang kota. Melalui penelusuran evaluasi KBS dengan Peta Hijau dan memposisikan KBS sebagai ruang publik kota, diharapkan KBS dapat menjadi sebuah tempat rekreasi edukatif yang berkelanjutan
