Imagery in visual arts: Managing the temperament of art criticism

Works of art can be described as narratives in shorthand where tangled mass of meaning and relationships are woven ‘seemingly’ inseparably by the instrumentality of a medium. The interpretation of this shorthand and the undoing of the ‘tangled mass of meaning, constitute the great area known as ‘art criticism’. The conservative intervention of personal emotions seems to be a fundamental characteristic of critical artistic judgment. This scenario attempts to invariably endorse the principle where “incorrect rights” and “correct wrongs” are equal to the answer, just as lullabies, in spite of tune differences, still lure babies to sleep. The tap root of emotional personification of judgment seems to continue to threaten the main line objectivity. This paper examines the issue of subjectivity ininterpretation vis-à-vis established principles of objective/impersonal judgment. Art criticisms or judgments establish their bridgeheads from the components of art object. In other words art criticisms ought to only be technically made through the channels provided by the components of an art work or object. Many of these principles are largely overlooked. Comments issuing from group or conference makings give away this subjectivity. The paper encourages the judges to play the game according to the rules

Experimental Investigation of Cutting Parameters on a Turning Tool Flank Wear (Industrial and Production Engineering)

Tool life has been a major source of concern to manufacturers, the extent of usefulness of any tool depends on it. The major cause of tool failure is tool wear and the most important aspect of wear to a machinist is the flank wear as it is the flank that is in direct contact with the work piece. This research investigates various cutting parameters and how they contribute to tool wear. The model used is the new wear model proposed by Palmai. The research involved the experimental investigation of turning on the Sumore SP 2110 lathe machine using ISOP Tungsten Carbide and High Speed Steel (HSS) as tools and Bright Mild Steel and Stainless Steel as work piece. The experimental data were used to calibrate the Palmai model for the various cutting tool and work piece pair, at different cutting parameters of spindle speeds depth of cut and feed rate. Experimental and Paimai wear results show good correlation, with about 1.5% to 5.4% deviation

People of the British Isles: preliminary analysis of genotypes and surnames in a UK control population

There is a great deal of interest in fine scale population structure in the UK, both as a signature of historical immigration events and because of the effect population structure may have on disease association studies. Although population structure appears to have a minor impact on the current generation of genome-wide association studies, it is likely to play a significant part in the next generation of studies designed to search for rare variants. A powerful way of detecting such structure is to control and document carefully the provenance of the samples involved. Here we describe the collection of a cohort of rural UK samples (The People of the British Isles), aimed at providing a well-characterised UK control population that can be used as a resource by the research community as well as providing fine scale genetic information on the British population. So far, some 4,000 samples have been collected, the majority of which fit the criteria of coming from a rural area and having all four grandparents from approximately the same area. Analysis of the first 3,865 samples that have been geocoded indicates that 75% have a mean distance between grandparental places of birth of 37.3km, and that about 70% of grandparental places of birth can be classed as rural. Preliminary genotyping of 1,057 samples demonstrates the value of these samples for investigating fine scale population structure within the UK, and shows how this can be enhanced by the use of surnames

Drawing as an instrument of professional excellence in visual arts: Problems and prospects

The drawing aspect of art programmes in many institutions of higher learning nationwide remains an area of academic phobia for some students. It seems to threaten students confidence and wears off their Grade Point Average GPA build-up. Several rounds of conversational engagements with some students leave a palpable evidence of loathsomeness towards drawing classes. Many of these students, in their more sober moments, confide in their peers, or less often, in their ‘senior friends’ who are the lecturers. This paper looks into the above scenario and tries to locate the foundational reasons for this fear, and in that rubble, find the remote and immediate causes. It also tries to provide a string of formulae possibilities which, hopefully, will lead the affected students into freedom. It is hoped that this paper will provide a basis for an all-round solution to drawing problems, whether created by students, parents or the teachers themselves. A diligent consideration of the issues raised here is suggested for all drawing stakeholders
