Language and Development Research in Africa : Based on Kiswahili, Buli and Akan Traditions
Amidu, Assibi A. 대한언어학회 2001 언어학 Vol.9 No.1
Amidu, A. Assibi. 2001. Language, Culture, Gender and Development Research in Africa: A View Based on Kiswahili, Bull and Akan Traditions. The Linguistic Association of Korea Journal 9(l). 45-71. Language is a vehicle of education, both formal end informal. Development researchers and workers are informal educators. They bring new ideas and assistance to recipient-consumers in such a way as to improve the quality of then lives. This paper argues that language c and encodes important cultural features and practices which often work against the goals of the development researcher and worker. For example, in Kiswahili, a man marries -oa 'marry', but a maimed -olewa 'be married'. The social roles of men and women such a society are, therefore, also linguistically determined. It follows that work on gender equality, for example, needs to take into account this kind of knowledge and information. In addition, linguistically encoded information often carried implications of loyalty to a group and recipients of development aid and ideas need to be educated in a way that enables them to see the advantages of accepting ways of doing things without feeling a of disloyalty to their new c sense ulture and community . The interrelationship between language and culture so strong as to require a special place in development research and field work planning and training.

The Syntax and Semantics of Naming Strings in Kiswahili Classes

Amidu, Assibi A. 2006. The Syntax and Semantics of Naming Strings in Kiswahili Classes. The Linguistic Association of Korea Journal, 14(1), 295-312. This study, firstly, demonstrates how the pronoun nani 'who?' rather than nini 'what?' is used in Kiswahili naming strings. We illustrate in the process that a peculiarity of naming strings in Kiswahili is that WH nani appears to refer not to the name of a person or even the nouns jina/majina 'name/s' but rather to the person who bears a name. Secondly, the study reveals that nani 'what?' is polysemic, i.e. it is a [±animate] denoting word that can also express the meaning of nini 'what?' in Kiswahili. The evidence illustrates how a common and allegedly animate denoting WH pronoun has the primary sense of the inanimate denoting WH pronoun nini while it is still a member of the so-called animate classes 1/2. Thirdly, we illustrate how predicate verbs connected with naming or mentioning or writing names take concords of classes 1/2 or 5/6 or both. We conclude that the key to the behaviour of nani lies in its polysemy. This underscores the limitations of semantic assignment rules in Bantu.

<P><B>Abstract</B></P> <P>Two-phase heat exchanger immersed in a passive containment cooling water storage tank (PCCWST) is a key component of the passive containment cooling system (PCCS) in light water reactors. Condensation and boiling heat transfer phenomena taking place on the inside and outside walls are crucial to the performance of the heat exchanger tube. The performances of such phenomena can be readily affected by the inclination angle of the heat exchanger tube under buoyancy-driven convection conditions in a PCCWST. However, to date no systematic examination of the effects of inclination angle on pool heat exchanger performance has been reported. This paper presents the results of numerical and experimental analyses of how inclination angle affects the performance of a single steam condensation tube immersed in a saturated water pool. To concurrently predict the two-phase heat transfer processes inside and outside the heat exchanger tube, an explicit heat structure coupling of two thermal-hydraulic codes was implemented using open media models. An experimental facility was also constructed to test a single-tube heat exchanger under the same conditions as the simulation. A comparison of simulation data and experimental results obtained for the reference case (tube inclination of 30°) confirmed that the coupled code could predict the heat transfer rate in the pool heat exchanger within the error limits of the experimental measurements. In light of this, additional simulations and experiments were conducted at varying inclination angles, from 3° to 90°. The results of simulations and experimental studies revealed that the heat transfer rate of a heat exchanger tube in a saturated pool is hardly influenced by tube inclination. Although an increase in inclination angle caused the vapor slug to spread around the heat exchanger tube surface, preventing liquid from getting to the surface of the tube, thereby decreasing boiling heat transfer coefficients, this was compensated for by an increase in condensation heat transfer coefficients as the inclination angle increased as a result of accelerated condensate liquid film in the tube. Thus, the overall effect of inclination angle on the thermal performance of a single-tube pool heat exchanger is inconsequential.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Performance of a single condensation tube immersed in a saturated pool was studied. </LI> <LI> Explicit heat structure coupling of CUPID and MARS codes was implemented. </LI> <LI> Simulations using coupled code and validation experiments were performed. </LI> <LI> Inclination angle has no significant effect on performance of a condensation tube. </LI> </UL> </P>
Language Teaching and Semantic Interpretation in Kiswahili Classes
Amidu, Assibi A 대한언어학회 2003 언어학 Vol.11 No.3
Interpretating language requires a constant update of the linguist's knowledge of linguistics. This is especially important for the foreign language teacher who is also an interpreter of other people's thoughts and world views reduced to linguistic texts. In this study, I demonstrate that there is a relationship between grammatical description, language teaching and semantic interpretation. I demonstrate my claim by examining some of the weaknesses of semantic and agreement assignment rules in Kiswahili Bantu.
