Abstract

The sign languages of the Deaf are visual natural languages that are created among the Deaf and transmitted from generation to generation within their community. Although research on sign languages and Deaf cultures is indispensable for understanding human languages and cultures in general, few studies have examined the sign languages of Africa, and there are no general introductions to the subject. Therefore, this paper outlines the sign languages of Africa and points out future research issues. It presents an original sign language map of Africa, and reviews the following, based on analyses of data collected through fieldwork and documentation.(1) Africa has at least 23 sign languages. Most are named after African nations and not after African ethnic groups. Of the 23 sign languages, some originated in Africa and others from foreign sign languages. In addition to these 23 sign languages, the Deaf on the African continent use other sign languages, including “Franco-American Sign Language” observed in Cameroon, which is a pidginized American Sign Language that is shared among Deaf communities in several nations in West and Central Africa. Some of the African sign languages have distributions that are completely independent of those of African spoken languages.(2) Foreign sign languages have been introduced to Africa, mainly from Europe and America. At least 13 foreign sign languages have been introduced to at least 27 African nations. Most of these introductions were related to the spread of Deaf education in the postcolonial era and not to colonial rule by Western powers. The presence of sign languages from America and Nordic countries is significant in Africa, and these languages have common characteristics, as they are from countries that are advanced in the field of Deaf education using sign languages.(3) In the urban Deaf community of Cameroon, multi-ethnic Deaf people share a unique sign language. The ethnic diversity of Cameroon divides neither the sign language of the Deaf nor their Deaf identity.On the basis of these results, I advocate a model of a “national Deaf community”, which can be stated as follows: “a national Deaf community has been newly constructed in each nation despite the linguistic and ethnic diversity of Africa.” As a conclusion, I suggest future research that is needed to understand “other linguistic cultures of Africa” considering the autonomous dynamics of sign languages.

... There has been various arguments about the citation patterns of review article, even though the review papers gain more citations as compared to other publication form document types (Jerrells, 2000;Ketcham & Crawford, 2007;Seglen, 1997). The review article entitled "The myth of language universals: Language diversity and its importance for cognitive science" (Evans & Levinson, 2009) Throughout the globe there are more than 230 different sign languages used which includes 44 languages family from Africa region (Kamei, 2004); 54 language family from American region; 55 language family from Asia-Pacific region; 47 language family from European region; and 22 from Middle East region. These includes both standard and local sign languages (Brentari, 2010;Fischer, 2014). ...

The people with disabilities have been provided with equal rights in terms of accessing information and learning resources. Over the time, there is transformation taking place where technology is being used to deliver information to the people with disabilities. Sign language is one such example of medium of communication for the people with hearing disabilities. There is large number of sign languages being used across the globe and each of these sign languages has its own way of communication. The Information and Communication Technology is playing a key role through using various software, mobile apps and library is a place which is actively involved in imparting custom-made services to the people with disabilities. This paper is an attempt to analyze the technology trends in sign languages and role of the libraries. The bibliometric methods have been used to analyze the trends. The study unfolds how the new tools and techniques are emerging over the time fostering the process of information communication.

A number of African signed languages are claimed to have originated from American Sign Language ASL (Asonye, 2016;Nyst, 2010) and others have their bearing from British Sign Language BSL and French Sign language LSF (Nobutaka, 2004). The undue influence on some of these African signed languages by the foreign languages is felt till this day. ...

This article makes a strong argument that the subtle but continuous marginalization of "lesser-developed" signed languages by "more-developed" ones, especially in Africa amounts to a situation of linguistic genocide.

The UN 1948 Convention on Linguistic Genocide did not expressly consider the gradual but continuous suppression of minority languages and cultures by a superior one and/or the authorities, which has been the situation with, not just the spoken languages as has been emphasized in literature, but the signed languages in Africa. However, the Convention’s definition of ‘genocide’ includes “…destroying in whole or part, or of preventing preservation or development.” Significant number of African signed languages are said to have originated from American Sign Language ASL (Asonye, 2016), a few others have their bearing from British Sign Language BSL and French Sign language LSF (Nobutaka, 2004). Some of these African signed languages are still threatened or at least influenced by their foreign “parent languages” till this day. While the indigenous African signed languages are struggling to emerge, and develop, the undue influence of their foreign counterparts continue to suppress the languages, delude the users, learners and even teachers of the languages. Edward (2015a) and Asonye (2016), both have reiterated the gradual endangerment of signed languages used in Africa, which is claimed to be caused by contact with spoken languages, local laws, formal education, and other post-colonial ideologies. Thus, these signed languages are gradually being battered by social and educational policies. Apart from village sign languages, many African countries can also boast of national sign languages. This paper argues that the Africa’s deaf communities are rich in signed languages which are sustained by several socio-cultural factors including the obvious lack of linguists’ interest to study signed languages, and have been under the continued attack of the colonist languages and cultures considered superior because they are documented and largely studied, It also seeks to demonstrate patterns of the effects of linguistic genocide on signed languages in Africa and their users. Examples are drawn from the signed languages used in selected deaf communities in Nigeria and Ghana. A multidisciplinary approach was used in the data collection and analyses, which includes simple questionnaires and interviews from deaf individuals, deaf educators, and signed language instructors. A large corpus of indigenous signed language items was also collected from different deaf communities and were analyzed and findings show that these signed languages have developed unique structural features distinct from the ASL, Signed English or any other imposed signed language.
... There are at least 23 different African Sign languages ( Kamei 2004) including Tunisian Sign Language, Tanzanian Sign Language, Gambian Sign Language, etc. Sign languages are relatively vulnerable minority languages based on population size. For the most part, efforts to develop Sign languages are not revitalization efforts, per se. ...

Medieval and classical periods in African history are a particular focus of this survey of language contact patterns seen on the African continent. The effects of languages associated with empires and kingdoms are shown to vary widely, with many such languages remaining influential even in the present day. Disentangling earlier patterns of language contact is a necessary step for those interested in reconstructing and classifying African languages. The great time depth and diversity found within each of the major African language phyla is mirrored by a dizzying array of contact patterns both within and across these phyla.

Language contact - the linguistic and social outcomes of two or more languages coming into contact with each other - has been pervasive in human history. However, where histories of language contact are comparable, experiences of migrant populations have been only similar, not identical. Given this, how does language contact work? With contributions from an international team of scholars, this Handbook - the first in a two-volume set - delves into this question from multiple perspectives and provides state-of-the-art research on population movement and language contact and change. It begins with an overview of how language contact as a research area has evolved since the late 19th century. The chapters then cover various processes and theoretical issues associated with population movement and language contact worldwide. It is essential reading for anybody interested in the dynamics of social interactions in diverse contact settings and how the changing ecologies influence the linguistic outcomes.

There are a large number of African languages and language families which display the linguistic effects of previous contact. This study provides a detailed survey of pre-modern contact patterns in different geographic zones across the continent. Contact patterns in Northern, Central and Southern Africa are complex, yet still less dense than those found across Africa's middle belt, where the continent is widest. This middle belt includes Northeast Africa, East Africa, the Rift Valley, and the sub-Saharan fragmentation belt, also known as the Sudanic Zone. Disentangling the contact patterns in this middle belt will be a long process that will necessarily go hand in hand with the reconstruction of Niger-Congo and Nilo-Saharan language phyla. This study includes a survey of the linguistic effects of contact, and a survey of those contacts that might be attributed to various kingdoms and empires. Kingdoms and empires undoubtedly had linguistic effects, but these effects vary greatly, depending on the patterns of social interactions which actually took place during the periods of political dominance. In some cases, there is evidence of language shift, while in other cases, there has been only a slight effect on the lexicon. In other cases, convergent grammatical systems have been found. Language shift may occur in a single generation and does not require an extensive period of political domination to occur.

Recently, much effort has been devoted to the development of battery separators for lithium-ion batteries for high-power, high-energy applications ranging from portable electronics to large-scale energy storage for power grids. The separator plays a key role in battery construction because it functions as the physical barrier to prevent electronic contact between the two electrodes and at the same time serves as an electrolyte reservoir, facilitating the ionic conduction. The purpose of this Review is to describe the requirements and properties of membrane separators for lithium-ion batteries, the recent progress on the different types of separators developed, and the manufacturing methods used for their production. Specifically the large-scale manufacturing processes are highlighted along with the processing parameters that affect their properties. The outlook and future directions regarding the development of advanced separator technologies are also discussed.

Nigeria, with its approximately 100 million inhabitants, is the most populated country in Africa. Hausa is the majority language of much of northern Nigeria and the southern parts of the Republic of Niger. There are an estimated 50 million Hausa speakers of which up to 40 million live in northern Nigeria and up to four million live in Niger (Wolff 1993, 1-2). Colonies of Hausa settlers can also be found in other parts of West Africa. Approximately 80%-90% of the estimated 25 million people whose mother tongue is Hausa live in northern Nigeria. The Hausa-speaking heartlands include the areas of Kano, Katsina, and Sokoto. This chapter focuses on the deaf community in Kano State and is based on ethnographic data collected during 18 months of fieldwork in northern Nigeria between 1994 and 1998. The state capital, Kano City, with its approximately two and a half million inhabitants, is the largest and most important Hausa city.

This chapter shows how MuSIASEM can be employed to generate an integrated assessment of the feasibility, viability and desirability of alternative energy sources, and more in general to characterize scenarios of alternative exosomatic metabolic patterns of society. The analysis focuses both on the potential contribution (quantity) and convenience (quality) of two potential alternative primary energy sources for the production of electricity in South Africa: concentrated solar power and woody biomass. The chapter illustrates how to integrate technical and spatial analyses into the multi-level system of accounting.

From the seventeenth century to the early years of the twentieth, the population of Martha's Vineyard manifested an extremely high rate of profound hereditary deafness. In stark contrast to the experience of most deaf people in our own society, the Vineyarders who were born deaf were so thoroughly integrated into the daily life of the community that they were not seen--and did not see themselves--as handicapped or as a group apart. Deaf people were included in all aspects of life, such as town politics, jobs, church affairs, and social life. How was this possible? On the Vineyard, hearing and deaf islanders alike grew up speaking sign language. This unique sociolinguistic adaptation meant that the usual barriers to communication between the hearing and the deaf, which so isolate many deaf people today, did not exist.

It is approaching a half century since Bill Stokoe published his revolutionary monograph, Sign Language Structure: An Outline of the Visual Communication Systems of the American Deaf It is rare for a work of innovative scholarship to spark a social as well as an intellectual revolution, but that is just what Stokoe's 1960 paper did. And it is indicative both of Stokoe's genius and of his commitment that he did not simply publish his groundbreaking work and then sit back to watch the revolutions unfold. He actively promoted important changes in at least three areas of social and intellectual life. First, and perhaps most important, his work, that was ultimately generally accepted as showing the signing of deaf people to be linguistic, supported significant changes in the way deaf children are educated around the globe. Second, his work led to a general rethinking of what is fundamental about human language; and, third, it helped to reenergize the moribund field of language origin studies. This truly revolutionary paper has been reprinted at least twice, in revised and original versions, since its initial release in 1960, and now, five years after Bill's death, it is good to see it once again brought before the general public. - David F.
