Human-computer interaction for development (HCI4D):the Southern African landscape

Human-Computer interaction for development (HCI4D) research aims to maximise the usability of interfaces for interacting with technologies designed specifically for under-served, under-resourced, and under-represented populations. In this paper we provide a snapshot of the Southern African HCI4D research against the background of the global HCI4D research landscape.We commenced with a systematic literature review of HCI4D (2010-2017) then surveyed Southern African researchers working in the area. The contribution is to highlight the context- specific themes and challenges that emerged from our investigation

West African English in Digital Discourse

This paper applies sociolinguistic and discourse-analytical approaches to examine the features of West African English (WAE) in digital discourse. Data comprises 23,374 posts and responses from some popular social and political online forums hosted by Nigerians (i.e. Nairaland and Naijapals); Ghanaians (i.e. Ghanaforum.com), and Sierra Leoneans (i.e. Sierra Online club and Sierra Leone Forum). These digital forums have served as social media platforms for discussions and debates on, and responses to recent socio-political events in those countries. Findings show that three varieties of WAE are evident in online discourse namely, the acrolect (high), mesolect (middle), and basilect (low), which sometimes depend on the educational level of the users. The local pidgin is also frequently used especially in the Nigerian forums. These varieties in turn reflect features that are characteristic of WAE such as (i) loan words within the standard (acrolect) variety (ii) code-switching between the standard variety and pidgin/Krio (iii) evidence of deviants/errors characteristic of the basilect variety and (iv) linguistic creativity such as coinages, and the language style of the Internet. Findings further show that West African online communicators in English have adapted their socio-cultural nuances of language use to modern information technology

No. 26: Social Media, The Internet and Diasporas for Development

The recent focus on diasporas by policy-makers researchers has highlighted the rich potential of migrants as a force for shaping development activities in their countries of origin. The study of diasporas in development presents researchers a number of significant challenges. As Vertovec and Cohen suggest, ‘one of the major changes in migration patterns is the growth of populations anchored … neither at their places of origin nor at their places of destination’. The fluid, multi-sited and multi-generational nature of diaspora groupings poses considerable methodological challenges of definition, identification, location, sampling and interviewing. As the nature of African diasporas are constantly in flux so too should the methodologies we use to study them. In practice, traditional approaches lead to the same methodological roadblocks. Census and immigration data (particularly from destination countries) can provide an overall picture of diaspora stocks, flows and locations. However, privacy issues generally preclude these sources from providing disaggregated data at the level of the individual migrant or migrant household. Surveys of diaspora members have therefore become the standard means of collecting information on diaspora characteristics, identities, activities and linkages. This immediately raises a set of problems and challenges. Census data can tell us the size of the population to sample but not who the individuals are, where they live and how to contact them. Without a sampling frame, researchers tend to rely instead on ‘snowball’, ‘purposive’ or ‘convenience’ sampling. This has produced a disproportionate number of studies that rely on key informant and focus group interviews in order to create a profile of diasporas and their development-related activities. Diasporas are often geographically dispersed within a country and across different countries. Cost and time constraints and the bias of snowball and convenience sampling lead to a focus on sub-sets. Studies of diaspora members in particular cities or regions are especially common. While sample sizes vary considerably, there is a marked reliance on very small samples, which raises obvious questions about the representativeness and generalizability of the findings. The mail-out survey is still the preferred method of reaching members of a geographically dispersed diaspora, although response rates remain stubbornly low. To contact members of the diaspora, mailing lists are compiled from organizations that keep, and are willing to share, membership lists (such as diaspora organizations, embassies, alumni associations, immigrant service agencies and religious organizations). However, this means an inherent sampling bias since data collected from these individuals and groups has the potential to be skewed towards diaspora members actively engaged with their origin country. This method of ‘accessing the diaspora through the diaspora’ is also unlikely to provide much information on ‘hidden’ members of a diaspora whose immigration status may be undocumented or uncertain and who are wary of disclosing personal information directly to researchers. Researchers have also noted that members of vulnerable populations such as asylum seekers and refugees might be reluctant to provide personal information due to fear and trust issues. To identify and connect with larger numbers, different strategies need to be adopted. In this context, the potential of the internet has rarely been considered. Since the advent of the internet age, more than one billion people have become connected to the World Wide Web (WWW), creating seemingly limitless opportunities for communication. The past decade has also seen a major increase in the use of the internet by diaspora individuals and groupings. The internet has not only facilitated remittance transfers, but has increased communication among and between diasporas and influenced the formation of diasporic identities. In this context, the potential of web-based methodologies in diaspora research appears promising. The aim of this paper is twofold. First, we argue for supplementing conventional approaches with new methodologies that embrace the connectivity of diasporas, the emergence of social media and the potential of online surveys. Second, we illustrate the potential of this approach through discussion of the methods adopted in our current research on the African diaspora in Canada

No. 69: Calibrating Informal Cross-Border Trade in Southern Africa

Informal cross-border trade (ICBT) is a significant feature of regional trade and international mobility in Southern Africa. The exact number of participants and economic importance of this trade is unknown because no official statistics are collected. Despite its obvious presence at every border post throughout the SADC region, ICBT remains largely invisible to policy-makers. Indeed, in government circles it is more often associated with smuggling, tax evasion and illegality than with innovation, enterprise and job creation. On the research side, there is a growing body of case study evidence that ICBT plays a critical role in poverty alleviation, food security and household livelihoods in Southern Africa. But its overall character and significance is unknown. With this in mind, SAMP initiated a project to examine cross-border regional trade at a selection of important border posts throughout the region. This research led to a number of country reports that provided rich insights into ICBT in particular countries. This report combines the data collected by each of the country teams and analyses the data set as a whole. The first issue addressed in the report is whether ICBT traders are a homogenous group. The research shows that this is far from being the case and that more attention needs to be paid to different types of traders and trading activity. Second, the report examines the activities of cross-border traders including the types of goods traded, the sources of those goods and where they are sold. While the majority of traders purchase goods from formal outlets in their countries of destination, most of these goods enter the informal economy on their return home. Third, the report examines financial transactions at the borders showing that most traders pay extremely small amounts of duty, which hardly justifies the effort of collecting it. On the other hand, only a small minority collect the VAT they are owed when they leave the country of purchase. Finally, the report itemizes the problems and challenges faced by informal traders when crossing borders. In total, the SAMP survey covered 20 land border posts connecting 11 Southern African countries using a threefold methodology. First, all people crossing through the selected border posts were monitored over a 10-day period and the number of ICBT traders counted. Second, the interactions of traders with customs officials were observed and the types, value and volumes of goods declared and duties paid were recorded. Third, a sample of traders was interviewed using an origin and destination (O&D) survey. During the course of the exercise, more than 205,000 people, including 85,000 traders, were counted passing through these border posts. The transactions of over 5,500 traders with customs officials were monitored and over 4,500 traders were interviewed. The study demonstrates that informal cross-border is a complex phenomenon and not uniform across the region, or even through border posts of the same country. However, the overall volume of trade, duties paid and VAT foregone, as well as the types of goods and where they are produced, indicate that this sector of regional trade should be given much greater attention and support by governments of the region as well as regional organizations such as the Common Market for Eastern and Southern Africa (COMESA), SADC and the Southern African Customs Union (SACU). The major findings at the regional level were as follows: Demographically, women comprise a significant proportion of traders and constitute the majority of traders crossing through nearly half of the border posts surveyed, including one of the busiest at Beit Bridge between South Africa and Zimbabwe. At the same time, an unexpectedly large number of men were also involved in ICBT. Malawi and Zambia had significantly more male than female traders, for example. Most ICBT is bilateral in character; that is, traders tend to operate between their home country and one other country. Trading into a third country is comparatively rare. At the same time, the vast majority of traders crossing into a country with goods to sell are citizens of that country. ICBT by traders of other nationalities is uncommon. Although South Africa is a major source of goods purchased by traders, the absence of South African informal traders was very noticeable. The reasons why South Africans do not participate in ICBT requires further exploration but it stands in marked contrast to formal sector regional trade where South African companies predominate. ICBT is a neglected market opportunity for small-scale South African entrepreneurs and the obstacles to their participation need to be better understood. The majority of traders travelled frequently to other countries for short visits (sometimes for less than a day) to buy goods to sell in their home country, or to sell goods that they had bought for that purpose in their home country. Only 13% of respondents bought and sold goods while travelling (two-way trading). Frequency of tracel also varied both within and between countries, with traders in the Namibian (42%) and Zambian (25%) surveys being most likely to travel every day. Others travel at least once a week (Mozambique, 67%; Zambia, 34%). Some travel less frequently, but at least once a month. Very few stay more than a month in another country. The types of goods carried by informal cross-border traders vary widely, but at most borders the trade was dominated by food, especially groceries and fresh produce. Again, there was considerable variability at different borders. New clothes, household and electrical goods comprised a significant proportion of the stock of some cross-border traders. Other goods identified in the survey included second-hand clothing, petrol, alcohol, car parts and construction materials. Traders mostly source their goods from the formal sector of destination countries. A small proportion obtain their goods from informal markets in other countries. Many traders acted as wholesale importers of goods, selling the goods they carried across borders to vendors in informal markets. Others sold from their own stalls in informal markets, door to door, or to networks of family, friends and other individuals. A small proportion sold to retailers and restaurants in the formal sector. The value of goods carried by traders indicates the complexity and diversity of this sector. A significant cohort of traders appeared to be survivalists as many said they carried less than ZAR500 worth of goods. However, at least some of these traders travel frequently with low-value loads, rather than infrequently with high-value loads. Most traders travelled with loads in the range of ZAR1,001-5,000. A small cohort of traders travelled with loads worth more than ZAR15,000. Informal traders make a relatively significant contribution to duties collected at border posts. During the 10-day survey period at the 20 border posts, ZAR3,750,000 was collected from 1,780 traders. Duties collected varied between and within border posts. In some surveys the value of duties paid per trader was less than ZAR50. Interestingly, duties were being incorrectly collected at some borders between Southern African Customs Union countries (for example, between Botswana and Swaziland and South Africa). Traders said they were willing to pay duties, but wanted amounts reduced and the process to be more transparent. Although most traders buy their goods in the formal sector, few claim VAT when leaving the country of purchase. Many did not know they could do this while others said that the systems are too complex and time consuming. Traders who do not claim VAT back make an unintended contribution to the fiscus of the country where they buy their goods. Responses to questions about treatment from officials at the borders were generally positive but varied between and within border posts. Larger and busier posts generally received less favourable reviews. The scope and scale of informal cross-border trade across the SADC suggests that it makes a significant contribution to regional trade and the retail economies of the region and is consistent with the stated aims of both the SADC and COMESA to promote intra-regional trade. Small-scale cross-border trade could, if promoted and supported, provide a route to the development of pro-poor trade policies that could have a direct impact at the household level. If trade policies for the region are to be successful, the activities of these entrepreneurs need to be included in planning processes. ICBT comprises a significant component of regional economic activity for most countries in Southern Africa. It is highly visible at border posts throughout the region. Only amongst policy-makers and governments does it remain largely invisible

Location Advantages, Governance Quality, Stock Market Development and Firm Characteristics as Antecedents of African M&As

This study explores firm- and country-specific antecedents of African M&As. We use one of the largest datasets to-date consisting of 1,490 unique African firms (11,183 firm-year observations) from 1996 to 2012. Our results suggest that improvements in time-varying country-level factors, including location advantages (market size, human capital and efficiency opportunities), national governance quality, and stock market development are associated with an increase in the volume of M&A activity. Consistent with the resource-curse paradox, high resource endowments are not associated with increased levels of M&A. In support of the management inefficiency but contrary to the traditional firm size hypotheses, African targets are generally characterised by declining stock returns and accounting profitability but are more likely to be larger firms; suggesting the presence of information asymmetry concerns in their selection. Notwithstanding, we find evidence of heterogeneity across countries with inconsistent support for established target prediction hypotheses. A model which combines firm- and country- specific factors better explains observed variations in African M&A activity

Family eating and physical activity practices among African American, Filipino American, and Hispanic American families: Implications for developing obesity prevention programs

Overweight and obesity among children and adults is well-documented as an escalating problem. The purpose of this study is to determine the blood pressure, self-esteem, and eating and physical activity practices among African Americans, Filipino Americans, and Hispanic Americans; and project implications for development of childhood obesity prevention programs. This descriptive study was conducted in a convenience sample of 110 mothers recruited in health clinics and community centers located in Southeast Florida: 19% African Americans, 26% Filipino Americans, and 55% Hispanic Americans. The data, collected via self-administered questionnaires and a guided interview (Family Eating and Activity Habits Questionnaire, Rosenberg’s Self-Esteem Scale, Background Information Questionnaire), were analyzed via descriptive and inferential statistics with findings significant at p \u3c .05. Results revealed differences and similarities in eating and activity practices between Filipinos and Blacks or Hispanics. Blood pressure and self-esteem did not differ by ethnicity; however, overweight mothers tended to have overweight children. The results point clearly to the importance of the mothers’ role modeling in eating and physical activity practices of families, reflecting the influence of mothers’ behaviors in children’s healthy behaviors, albeit family health. Given that mothers own physical exercise and eating habits could influence their children’s physical activity levels and food choices, a parental advice strategy could be disseminated directly to parents by health professionals. Study findings may raise public awareness of the increasing prevalence and consequences of overweight and obesity in children and adolescents, particularly among vulnerable ethnic groups. The findings provide a database for nurse practitioners and other health service providers for the development of culturally sensitive focused public health education programs to prevent or control obesity

The consequences of online information dissemination on stock market liquidity and efficiency: Implications on African markets

From the Efficient Market Hypothesis, a market is efficient if security prices fully and correctly reflect all available information that is relevant for the stock’s pricing. This requires a medium of information dissemination and transaction ordering with both speed and accuracy. This paper chronologically presents arguments in favour of the internet as one such medium. The internet has also enabled the transmission and archiving of bulky information in a ready-to-use format. And abnormal returns are now quickly observed and arbitraged away to non-existence. Using correlation analysis, we find a positive relationship between the internet and some stock market development indicators.Efficient market hypothesis; internet; online information; stock market; development indicators; Africa

Manual of tropical bryology

Bryophytes belong to the oldest land plants. They existed already in the Palaeozoic 300 mio years ago in forms which were hardly different from the extant species. They remained relatively unchanged with relatively low evolution rates (and are thus often called a „conservative“ plant group), but could successfully establish themselves in an always varying environment from Devonian swamps to Permian forests, Mesozoic deserts and as epiphytes in Tertiary rainforests. They are not eaten by snails or insects, and are resistant against fungi and bacteria

Escaping from American intelligence : culture, ethnocentrism and the Anglosphere

The United States and its closest allies now spend over $100 billion a year on intelligence. Ten years after 9/11, the intelligence machine is certainly bigger - but not necessarily better. American intelligence continues to privilege old-fashioned strategic analysis for policy-makers and exhibits a technocratic approach to asymmetric security threats, epitomized by the accelerated use of drone strikes and data-mining. Distinguished commentators have focused on the panacea of top-down reform, while politicians and practitioners have created entire new agencies. However these prescriptions for change remain conceptually limited because of underlying Anglo-Saxon presumptions about what intelligence is. Although intelligence is a global business, when we talk about intelligence we tend to use a vocabulary that is narrowly derived from the experiences of America and its English-speaking nebula. This article deploys the notion of strategic culture to explain this why this is. It then explores the cases of China and South Africa to suggest how we might begin to rethink our intelligence communities and their tasks. It argues that the road to success is about individuals, attitudes and cultures rather than organizations. Future improvement will depend on our ability to recognize the changing nature of the security environment and to practice the art of ‘intelligence among the people’. While the United States remains the world’s most significant military power, its strategic culture is unsuited to this new terrain and arguably other countries do these things rather better
