Gregory of Nyssa's mystical eschatology

The original context in which Gregory preached the homilies on the Song of Songs is debated, however scholars agree on the point that the reason why they were delivered was to offer his audience a series of meditations on the biblical text, concentrating in particular on the ascetic journey the soul of the Christian is called to make in order to reach perfection. In this long itinerary the Nyssen makes many references to the evil element that has soiled human nature after the fall. Therefore, one of the necessary pre-requisites for the soul to advance in the ascent towards perfection is to free itself of this evil stain. We shall therefore briefly illustrate how Gregory’s interpretation of salvation history – generally associated with his treatises – is given in remarkable detail in this cycle of homilies.peer-reviewe

Teaching moral ethics through sermons. A case study on Gregory of Nyssa

This article studies six sermons related to proper social behavior from a Christian perspective by fourth-century theologian Gregory of Nyssa. A brief comment on the dating and the context of the sermons is given before the different themes discussed in the different liturgical seasons are analyzed, and then the content of each of these sermons is explored in some depth. Following this, an analysis of the persuasive and instructive styles in these sermons is made, underlining the different ways the bishop exhorts his people according to the matters at hand. When discussing issues that set a bad example, such as the practice of usury and the rejection of correction, the language used is very harsh; in other cases, the tone is softer, such as when it comes to deciding whether one should postpone his baptism or not or how one should behave vis-à-vis the more needy in society; when dealing with sensitive issues like fornication, given the natural human weakness in this aspect, the language is much more pastoral. Finally, a comment on the narratives used concludes the study.peer-reviewe

Gregory of Nyssa's treatment of ancient beliefs in his homilies

A discussion of Gregory of Nyssa's homilies with particular attentionto his treatment of non-Christian faiths, revealing his intent to demonstrate the superiority of Christianity. Through his arguments, he offers insights into the reasons underlying this conviction.In his many homilies, Gregory of Nyssa contrasts Christian belief to earlier forms of belief that were still very present in the Roman empire during the fourth century, namely the classical polytheistic faith and Judaism, with the explicit intention of showing its superiority over them. Even though Gregory is clearly against any belief that is not Christian orthodoxy, he presents these other beliefs from two different perspectives: at times, he presents them as the enemies of Christianity, showing clearly how they seek to harm the true faith; at other times, he also seeks to show how, in a way, they are of benefit to Christianity because their very presence and the behaviour of their followers help to show how much the Christian way of life outshines any other. This discussion on other faiths in relation to Christian belief is present in many contexts; however, attacks on paganism are more evident in the sermons in honour of martyrs, while invectives addressed to Jews are present mainly in his sermons on biblical books. In this paper, an attempt will be made to present in detail what Gregory has to say about these other faiths and their relation to Christianity (desired and factual), concluding with how his attitude towards other faiths can be classified and described.peer-reviewe

Towards intelligent early form design and prototyping, questionnaire results and analysis

Currently, the Department of Manufacturing Engineering (DME), University of Malta and the Istitito per la Matematica Applicata e Tecnologie Informatiche (IMATI), Genoa are conducting research on how simple components represented by sketches on normal paper can be converted to computer models. One of the key issues in developing a sketch recognition system is precisely to handle the trade-off between ease of computer recognition and the preservation of sketching freedom. With an attempt to address this issue, two sketching methods (or sketching languages) have been developed by the DME. This report presents the results of a questionnaire about the sketching activity itself and also about the two proposed sketching languages. An analysis of the results obtained is also presented with the scope to identify what should be the future directions that might contribute to enhance the usefulness of the two sketching approaches

Experiments with augmented reality for supporting education in distributed product design solution evaluation

This paper presents results of an experiment set up to exploit the impact of using Augmented Reality (AR) whilst groups of engineering design students from Malta, Scotland, London and Hungary were collaborating on designing different parts making up a car seat belt mechanism. In particular, the experiment focuses on the distributed, real-time evaluation of the emerging design solution. The results achieved are encouraging and the paper contributes insights of the suitability of using AR in distributed and collaborative design evaluation scenarios

'Form Design For Emotion' with a Cameraphone Based Tool

Merging emotional value into products has become an essential strategy for increasing a product’s competitive edge in the consumer market. Indeed, this approach instills emotional value into products, to satisfy human emotional needs. Combined with this is the fact that designers usually work outside their design office using pen and paper, since ideas are usually stimulated. Yet, designers lack mobile computer-aided sketching (CAS) tools which truly link paper-based sketching with computer-based 3D modelling tools. As a step in this direction, this poster presents a framework that extends CAS technology to cameraphones. Furthermore, this framework is capable of providing emotional guidance about a form concept to satisfy the emotional needs of the customer, directly on cameraphones. A proof-of-concept tool has been implemented and evaluated. Preliminary evaluation results with design engineers in the cosmetic cases industry, indicate the positive impact that technology based on the framework developed will have on DFe in practice

The synthesis of a liver tissue mimicking solution for microwave medical applications

This paper presents the synthesis of a mixture solution that is equivalent to ex-vivo liver tissue dielectric characteristics between 500 MHz and 5 GHz. The mimicking solution was synthesized using concentrations of two chemicals, the solute which is referred to as the inclusion phase and the solvent, referred to as the host phase. The inclusion phase consisted of bovine serum albumin (BSA) powder and the host phase consisted of a phosphate-buffered saline (PBS) solution with a concentration of Triton X-100 (TX-100). The dielectric properties of these two phases were substituted into Bruggemanʼs two-phase mixture equation to estimate the dielectric properties of excised liver. Furthermore, the study exploits Bruggeman’s equation to investigate the impact of tissue dehydration levels on the dielectric properties of an excised tissue. The effect of dehydration has been characterised as a function of time based on the loss-on-drying technique (a substance is heated until it is completely dry). Dielectric parameters were measured as a function of frequency using the Slim Form open-ended coaxial probe at a constant room temperature of circa 25°C. Measured dielectic data were fitted to the Cole-Cole model and good agreement with the mimicking solutions was obtained. These results indicate that these solutions can be used to model the human body phantoms for microwave medical applications.peer-reviewe

Towards life-oriented evaluation support of ‘interface concepts’

The evaluation of design concepts is a critical early design stage with potential ramifications on subsequent lifecycle phases. During this stage the engineering designer is typically required to evaluate multiple concepts with respect to conflicting criteria. Over the years academic research proposed numerous concept evaluation techniques in order to support the user at this critical stage. Yet this has yielded an additional problem in which the inexperienced user needs also to be guided in the selection of the appropriate concept evaluation technique. The research presented in this paper has the long-term objective of providing computer support to the user on 2 levels: the evaluation of design concepts and the selection of the appropriate concept appraisal technique. The research, presented in this paper focuses on the development of an approach for the evaluation of module interface design concepts.peer-reviewe

A profile-driven sketching interface for pen-and-paper sketches

This research is funded by the University of Malta under the research grant R30 31330 and is part of the project Innovative ‘Early Design’ Product Prototyping (InPro).Sketching interface tools are developed to allow designers to benefit from the powerful computational tools avail- able in computer aided design systems. However, despite the number of sketching tools such as PDAs and Tablet PCs available on market, designers typically create a number of initial conceptual ideas using paper-based sketches and scribbles such that these tools remain inaccessible to designers in the early design stages. In this paper we describe a profile-driven, paper-based sketching interface which infers the 3D geometry of objects drawn by designers using the traditional pen and paper sketching. We show that by making full use of the shape information present in the scribbled drawing, it is possible to obtain a paper-based sketching interface that retains the simplicity of the early- stage design drawings while allowing for the modeling of a variety of object shapes.peer-reviewe
