A Tapestry of People: The Growth of Population in the Province of the Western Cape

The best place to begin a study of human settlement is with climate. Most of the Western Cape province - the land lying north of a line running parallel to the southern coast approximately 100 kilometers inland, from Worcester to Uniondale - is too dry for arable farming. And the rain which does fall south of the long range of mountains tends to come in the winter months which is suitable for wheat but not for tropical cereals. Thus when ironworking, Bantu-speaking, people began to move east and then south from the Niger-Congo area in a great wave of migration that began some 2000 years ago they moved into the wetter eastern part of what is now South Africa where there was good grazing for their cattle and where the crops they knew - sorghum, millet and, later maize, - would grow...

Cellular repair/misrepair track model

A repair/misrepair cell kinetics model is superimposed onto the track structure model of Katz to provide for a repair mechanism. The model is tested on the repair-dependent data of Yang et al. and provides an adequate description of that data. The misrepair rate determines the maximum relative biological effectiveness (RBE), but similar results could arise from indirect X-ray lethality not include in the present model

A study of the generation of linear energy transfer spectra for space radiations

The conversion of particle-energy spectra into a linear energy transfer (LET) distribution is a guide in assessing biologically significant components. The mapping of LET to energy is triple valued and can be defined only on open subintervals. A well-defined numerical procedure is found to allow generation of LET spectra on the open subintervals that are integrable in spite of their singular nature

A Review of the second Carnegie Commission of enquiry into poverty in South Africa

African Studies Seminar series. Paper presented 29 July 1985What follows is the barest outline of some of the major issues emerging from the Second Carnegie Inquiry into Poverty and Development. I intend to flesh out these bones in the seminar in the hope of provoking critical discussion. This seminar will focus on poverty and the processes of impoverishment in Southern Africa, and on the second Carnegie Inquiry, which has been going on over the past five years. Background, and introduction: Purpose of the Inquiry is not just to document poverty, but to engage in policy-oriented research: research to assist the society to develop strategies to move away from poverty

The ugly in aesthetics

First we must admit representative ugliness tor purposes of realism, truth, and in connection with the significant the characteristic and such types. Also, we must admit distortion tor purposes of power, emotional strength, logical and organic consistency, and so forth. Possibly the ugly may be admitted to heighten beauty; and certain other forms of the ugly will be admitted artistically so long as comedy and tragedy are called art-forms. So far, then, as beauty in the wide sense is concerned, the first category or ugliness cannot be anti-thetical to beauty because it is included in, beauty, and is a positive factor of aesthetic enjoyment. What we have judged finally to be real ugliness is, on the other hand, opposed to beauty in that it is negative, a lack of what should exist in good art

When Youth Run for Office

The purpose of this work is threefold: to define the term ‘youth candidate’, to create a public data archive of youth candidates around the U.S., and to reveal what role age plays on the campaign trail for younger candidates. The first study shows the increase in young people running for office in the U.S.. The second study tells of age discrimination towards younger candidates on the campaign trail. Also within this document is an archive and photo album of youth candidates and their campaigns. The results of this research tell a data and experience-driven story of the quickly changing and ever-diversifying political landscape

Purposive variation in recordkeeping in the academic molecular biology laboratory

This thesis presents an investigation into the role played by laboratory records in the disciplinary discourse of academic molecular biology laboratories. The motivation behind this study stems from two areas of concern. Firstly, the laboratory record has received comparatively little attention as a linguistic genre in spite of its central role in the daily work of laboratory scientists. Secondly, laboratory records have become a focus for technologically driven change through the advent of computing systems that aim to support a transition away from the traditional paper-based approach towards electronic recordkeeping. Electronic recordkeeping raises the potential for increased sharing of laboratory records across laboratory communities. However, the uptake of electronic laboratory notebooks has been, and remains, markedly low in academic laboratories. The investigation employs a multi-perspective research framework combining ethnography, genre analysis, and reading protocol analysis in order to evaluate both the organizational practices and linguistic practices at work in laboratory recordkeeping, and to examine these practices from the viewpoints of both producers and consumers of laboratory records. Particular emphasis is placed on assessing variation in the practices used by different scientists when keeping laboratory records, and on assessing the types of articulation work used to achieve mutual intelligibility across laboratory members. The findings of this investigation indicate that the dominant viewpoint held by laboratory staff other than principal investigators conceptualized laboratory records as a personal resource rather than a community archive. Readers other than the original author relied almost exclusively on the recontextualization of selected information from laboratory records into ‘public genres’ such as laboratory talks, research articles, and progress reports as the preferred means of accessing the information held in the records. The consistent use of summarized forms of recording experimental data rendered most laboratory records as both unreliable and of limited usability in the records management sense that they did not form full and accurate descriptions that could support future organizational activities. These findings offer a counterpoint to other studies, notably a number of studies undertaken as part of technology developments for electronic recordkeeping, that report sharing of laboratory records or assume a ‘cyberbolic’ view of laboratory records as a shared resource
