THE ROLE OF MOTHER TONGUE AT PRIMARY LEVEL IN THE PRESERVATION OF CULTURE

KHAN, SHAHIDA HABIB 09 October 2013 (has links)
The UN Charter recognizes the right to culture as a human right and UNESCO mandates the preservation and enhancement of indigenous cultures – reflecting how the international community values cultural diversity. Ignoring the acculturating effects of education in foreign languages in indigenous societies comes in conflict with these mandates. Current research in the instructional languages of primary school education usually revolves around the learning advantages. But the focus on learning advantages has diminished the impact of instructional language on culture to relative oblivion, despite the acculturating effects visibly found in indigenous, multilingual, and pluralist societies; effects that threaten the existence of many indigenous cultures in the wake of globalization. As remarked by Ngugi Wa Thiong’o in his book titled The Future of African Literature, language is “a system of communication” and “the carrier of culture”, therefore, striking a balance between its role in education and culture is essential. Indigenous culture and language should not be sacrificed by education that seeks to educate for inclusion in a world viewed as a global; the latter representative of the western culture and English language. Therefore, a strategy is needed to use education systems both as carriers of indigenous cultures and participation in a global world. This topic requires continuous research. The purpose of this study was to explore the role of mother tongue at the primary school level in the preservation of culture. For this purpose, the relationship of Pukhtunwali culture with Pukhtu language was investigated. This qualitative study consisted of interviews with six primary school teachers teaching grade five social studies curriculum in Khyber Pukhtunkhwa. The teachers were asked to share their perspectives on the role of Pukhtu language used as a medium of instruction at the primary school level in the preservation of Pukhtun culture in Khyber Pukhtunkhwa. Data analysis identified five themes that showed variations in the perspectives of teachers regarding the role of Pukhtu language in the preservation of Pukhtunwali if used as a medium of instruction in schools. / Thesis (Master, Education) -- Queen's University, 2013-10-09 13:35:40.547

Characterisation of the South African Culicoides imicola (Kieffer, 1913) species complex, and its phylogenetic status in Europe

Linton, Yvonne-Marie January 1998 (has links)
C. imicola has been described as a species complex in South Africa on the basis of taxonomy, with at least seven species world-wide. Phylogenetic validity of five taxa within the Imicola group, namely C. imicola s.s., C. loxodontis, C. bolitinos and two currently unconfirmed species - Culicoides Sp. 30 (tuttifruitti) and Culicoides Sp. 107 (kwagga), were established using mtDNA COI sequence data, which confirmed their identity, not only as separate genetic entities, but also in exact correlation with the sibling species based on morphological and ecological parameters. In addition, the separate species status was reinforced for C. kwagga and C. tuttifrutti, which showed BCL of 100 with respect to C. imicola, using sequence data from the ITS-2 nuclear rRNA gene spacer region, and the mtDMA 16S gene respectively. Phylogeographical studies were undertaken using all three genomic regions, and revealed that C. imicola is present in Europe as C. imicola in sensu stricto, which acts as the vector for AHSV and BTV in this region. Intra-specific variation was highest in the COI amplicon, and extremely low in both ITS-2 and 16S regions. Phylogenetic resolution of internal clades was poorly supported for each gene region, and haplotype sharing suggests that the C. imicola populations across this wide geographical range are highly heterogeneous, with a high degree of haplotype mixing. Ecological field studies were carried out in farmyards in Spain and Portugal. When population composition of C. imicola was determined alongside host preference, it was found that although C. imicola are present in farms around cows, domestic fowl and pigs, they are present in higher numbers, comprise a higher total % of Culicoides caught and are present in a more stable population around horses. These results have serious implications for the spread of AHSV in these regions of Iberia where equestrian stud farms, producing quality polo and racing horses, play a significant part in the economy of the area.

Aspects of the development of the sense of taste in humans

Temple, Elizabeth C., University of Western Sydney, Hawkesbury, Faculty of Science and Technology January 1999 (has links)
Very little research has been conducted on the development of taste perception in humans. Therefore there is a lack of knowledge, first, about how children perceive taste, especially when compared to what is known about how adults experience taste, and second, about the functioning and development of the gustatory system, including when the system is fully mature and functioning in an adult-like manner. The aims of this thesis were (i) to investigate the growth pattern of the tongue throughout childhood / adolescence, and (ii) to determine the state of maturity of some of the aspects of the sense of taste in mid-childhood. Overall, the data in this thesis indicate that children respond similarly to adults with regard to single-point measures of sensitivity and perceived intensity, but there are some differences in the overall temporal experience of taste, from onset of perception through to extinction, and the way in which it is perceived by adults and 8-9 year old children.

Measurement of intraoral pressure during normal swallowing

Kennedy, Daniel Lloyd, n/a January 2008 (has links)
Aim: The aim of this research was to measure functional intraoral pressures using a newly developed method; specifically, three areas were examined. Firstly, this new approach to measurement allowed the equilibrium theory of tooth position to be re-addressed. Secondly, it allowed investigation the patterns of pressure change in the palatal midline during water swallowing. Lastly, this approach allowed a preliminary investigation of the affect of the viscosity of the food ingested on the pressures generated in the mouth. Methods: The participants were 6 healthy volunteers (4 males, 2 females) recruited from the post-graduate students at the University of Otago, School of Dentistry. The age range was 25 to 35 years. All had full permanent dentitions, Angle Class I occlusions (normal) with acceptable overbite and overjet relationship, and none of them had a history of previous orthodontic treatment. For each of the subjects a cast chrome-cobalt baseplate was constructed to house 8 miniature strain gauge pressure transducers (Precision Measurement Co. Michigan). The location of the sensors were standardised as follows: Three sensors were paired on the buccal and lingual surfaces of the central, canine and first molar. Two palatal vault sensors were placed in the midline of the palate, one at level of the distal of the first premolar, and the second slightly anterior to the junction of the hard and soft palate. Simultaneous recordings were taken during a set of tasks including water swallows, saliva swallows and food ingestion. Results: The results showed that swallowing was a highly complex wellcoordinated event, and that each individual had their own unique signature pattern of swallowing, characterised by pressure changes of high frequency, in excess of �1000 kPa/s. Conclusions: The analysis of the pressure acting on the teeth showed that although the pattern and magnitude of pressure generated varied among the group, the observation of waveforms would suggest a tendency for no inherent balance between the buccal and the palatal pressures on the teeth during swallowing for any of the individuals tested. This investigation of the pressure in the midline revealed an aspect previously not fully explored; these experiments showed that there were large and persistent negative pressures generated during swallowing, that preceded the positive pressures and which appear important in bolus propulsion The patterns of swallowing and the magnitudes of pressure generated, changed with the different consistency of the various substances ingested. There was a general trend for increased pressures during swallowing of substrates that are more viscous; water showed the lowest pressures, followed by saliva and finally jelly. Keywords: Tongue pressure, Intraoral pressures, Tongue dynamics, Swallowing.

Unga romers skolsituation i Västerås i egenskap av nationell minoritet

Ljung, Ulrika, Andric, Ana January 2008 (has links)
<p>Syftet med uppsatsen var att utreda romska ungdomars skolsituation i Västerås samt att föra en diskussion om studiens resultat i förhållande till Europarådets ramkonvention om nationella minoriteter. Syftet utreddes dels genom intervjuer med åtta romska elever och tre lärare därefter tolkades resultatet utifrån ett intersektionellt perspektiv. Vidare diskuterades resultatet med utgångspunkt i relevanta delar av ramkonventionen. Studien är kvalitativ och empirin analyserades genom en hermeneutisk tolkningsprocess. Vad som framkom i resultatet är att majoritetssamhällets etnocentrism påverkar unga romers skolsituation i Västerås eftersom romernas särskilda rättigheter i egenskap av nationell minoritet inte beaktas. Skolsituationen försätter de romska ungdomarna i en marginaliseringssituation där de pendlar mellan majoritetssamhällets krav och familjens förväntningar.</p>

Matematik och Språk : Betydelsen av språket i matematik för andraspråkselever

Colak, Emine January 2011 (has links)
This paper investigates the methods used by teachers when teaching elementary mathematics to children with Swedish as their second language. The original mathematical terminology derives from Latin, Greek and Arabic, this terminology is not of great importance in this paper, the everyday language spoken in elementary classes when teaching mathematical concepts and calculations to younger children is. The use of everyday language is an advantage for children with Swedish as their second language as mathematical problems presented in a more plain language is easier to comprehend and solve than problems in mere numerals. Special teachers in home language classes often have the task of clarifying the mathematical concepts, introduced to the children during mathematical lessons, in the pupils first acquired language. A qualitative method was used in this study. The research material consists of interviews and observations. Two teachers and a home language teacher, all from one school, participate in the study. The research results show the importance of ordinary language terminology in mathematics for beginners. The participants of the study are aware of the importance of language in mathematics and actively work with the vocabulary in the languages involved. The various methodologies used to introduce mathematical vocabulary to the students differed among the teachers.

A biomechanical model of the human tongue for understanding speech production and other lingual behaviors

Baker, Todd Adam January 2008 (has links)
A biomechanical model of the human tongue was constructed, based upon a detailed anatomical study of an actual cadaver. Data from the Visible Human Project were segmented to create a volumetric representation of the tongue and its constituent muscles. The volumetric representation was converted to a smooth NURBS-bounded solid model--for compatibility with meshing algorithms--by lofting between splines, the vertices of which were defined by the coordinates of a smoothed triangular mesh representation. Using a hyperelastic constitutive model that allowed for the addition of active stress, the model deforms in response to user-specified muscle activation patterns. A series of meshes was created to perform a mesh validation study; in the validation tests performed, a 245,223-element mesh was found to be sufficient to model tongue behavior.Systematic samples of the behavior of the model were collected. Principal component analyses were performed on the samples to discover low-dimensional representations of tongue postures. Statistical models (linear regression models and neural networks) were fit to predict tongue posture from muscle activation, and vice versa. In all tests, it was found that a relatively small sample of tongue postures can be used to successfully generalize to larger data sets.Finally, a variety of specific tests were performed, based on claims and predictions found in previous literature. Of these, the claims of the muscular hydrostat theory of tongue movement were best supported. Simulations were also run that simulated lingual hemiplegia. It was found that substantially different muscular activation patterns were required to achieve equivalent postures in a hemiplegic tongue, relative to a normal tongue.
