A note on the sign (unit root) ambiguities of Gauss sums in index 2 and 4 cases
Recently, the explicit evaluation of Gauss sums in the index 2 and 4 cases
have been given in several papers (see [2,3,7,8]). In the course of evaluation,
the sigh (or unit root) ambiguities are unavoidably occurred. This paper
presents another method, different from [7] and [8], to determine the sigh
(unit root) ambiguities of Gauss sums in the index 2 case, as well as the ones
with odd order in the non-cyclic index 4 case. And we note that the method in
this paper are more succinct and effective than [8] and [7]
Complete Solving for Explicit Evaluation of Gauss Sums in the Index 2 Case
Let be a prime number, for some positive integer , be a
positive integer such that , and let \k be a primitive
multiplicative character of order over finite field \fq. This paper
studies the problem of explicit evaluation of Gauss sums in "\textsl{index 2
case}" (i.e. f=\f{\p(N)}{2}=[\zn:\pp], where \p(\cd) is Euler function).
Firstly, the classification of the Gauss sums in index 2 case is presented.
Then, the explicit evaluation of Gauss sums G(\k^\la) (1\laN-1) in index 2
case with order being general even integer (i.e. N=2^{r}\cd N_0 where
are positive integers and is odd.) is obtained. Thus, the
problem of explicit evaluation of Gauss sums in index 2 case is completely
solved
The old man and the letter: repertoires of literacy and languaging in a modern multiethnic Gambian village
Recent developments mark a âhuman turnâ in sociolinguistics, i.e., a move away from languages as linguistic systems used by people, toward language or languaging as a sociolinguistic system performed by people. This article inscribes itself in that tradition and offers a micro-ethnographic analysis of a literacy event in rural Gambia. The incident relates to a letter that was âwrittenâ by an old illiterate villager in the process of arranging a family memberâs marriage. Although the event in itself is fairly insignificant and trivial, it is mobilised to gain an insight into the social and cultural organisation of literacy and languaging in this village. The old manâs letter is a typical moment of âgrassroots literacyâ and is not âorthographicâ but âheterographicâ (reflecting more than one prescriptive regime) and âexographicâ (drawing on imported normativity). Local languaging here is not the sum of the local languages (Mandinka plus Jola plus Fula plus English) but is a complexly regimented repertoire in which different functions of language are distributed differently across languages and individuals
