Consumer intentions to buy nutrient-rich precooked bean snacks: does sensory evaluation matter?

Precooked bean products have the potential of bridging the common bean demand and consumption gap in Kenya. However, sensory evaluation of novel precooked processed products has been inadequate in determining acceptability. This study assessed the sensory evaluation of precooked bean snacks by 269 rural consumers in Machakos County of Kenya. Descriptive results indicated that less than one-quarter (22%) of the consumers were aware of the precooked bean products. The low awareness is a disconnect from the expectations that farming households were probably going to be aware of processed bean products because of their participation in bean value chain. Sensory evaluation showed that 75% of the consumers evaluated the freshness of the bean snacks positively, with about 90% and 63% of them positively assessing the taste of the precooked bean snacks branded Keroma Delicious and Keroma Fruity, respectively. The taste evaluation of Keroma Fruity brand significantly differed depending on age and level of education of the consumer. Similarly, the taste of Keroma Delicious brand also significantly differed by age and educational attainment of consumers. Furthermore, while consumers liked the taste parameters of the products, less than half of them liked the beany flavour of the two products. Results from the binary logit regression model indicated that freshness, sourness, and flavour positively and significantly predicted the probability of future purchases of Keroma Fruity bean snack brands. Consumer intentions to buy Keroma Delicious brand were positively predicted by flavour and marginally by sweetness. To accelerate the consumption of precooked bean products, product development and marketing strategies should recognise the role of sensory attributes in driving acceptability of the bean snacks, deploy processing technologies that retain and enhance sensory attributes, create awareness of the products, and segment the market from a gender lens in order to satisfy the diverse consumer needs and preferences

Rift Valley fever virus seroprevalence among ruminants and humans in northeast Kenya

Rift Valley fever (RVF) is a zoonotic vector-borne disease present in much of Africa, and the Arabic peninsula. During outbreaks, the case fatality is high in young ruminants and there may be abortion storms, human disease is usually mild but some may suffer fatal hemorrhagic fever. Outbreaks in East Africa occur after periods of heavy prolonged rains, such as during El Niño southern oscillations, which lead to a sudden increase in the number of vectors hatched. Between outbreaks, there are indications that the virus is still circulating in some ecologies. Kenya has suffered repeated serious outbreaks of RVF, with high morbidity in humans and animals, and also severe economic consequences. In the northern of Kenya, a hot spot for RVF outbreaks, there are continuous expansions of irrigation schemes, which enable the societies to be less susceptible to droughts. However, there are concerns that the increased irrigation would provide more vector breeding grounds, and thus cause people living close to be more exposed to vector-borne diseases. In this study, 1117 serum samples were collected from humans in the age 5-90 years old, in the irrigated area, a riverine area, and the close-by district where people are fully depending on pastoralism. Samples were tested with a competitive ELISA detecting both IgM and IgG antibodies. Overall seroprevalence was 21.9%, and univarible analyses could find no difference between the three areas, but men were found to be significantly more seropositive than women (26.2 and 18.8% respectively, p=0.004). Ruminants (sheep, goats, and cattle) were also sampled within the irrigation. A total of 1997 animals were sampled, and tested with the same ELISA as the human samples. Overall seroprevalence was 25.6%, with no difference between the seroprevalences in goats, sheep and cattle. Juveniles had lower seroprevalence rates than adults, 12.3% compared to 30.2% (p<0.001). Since the last outbreak occurred in 2006-2007, juveniles could not have been infected during that outbreak. In conclusion, the study confirms that RVF can be circulating in ruminants between epidemics in irrigation schemes. However, the human sampling did not show any evidence that living in irrigation schemes would make people more exposed, although the exposure detected here is cumulative and longitudinal surveys may be more suitable to detect differences in infection rates

Helminths and HIV infection: epidemiological observations on immunological hypotheses

Parasitic helminths have co-evolved with the mammalian immune system. Current hypotheses suggest that immunological stimulation in the presence of helminths is balanced by immuno-regulation and by the broad spectrum of mechanisms possessed by helminths for countering the host immune response. The degree to which this balance is perfected, and the mechanisms by which this is achieved, vary between helminth species; we suggest that this is reflected not only in the degree of pathology induced by helminths but also in a variety of relationships with HIV infection and HIV disease. Available epidemiological data regarding interactions between helminths and HIV are largely observational; results are variable and generally inconclusive. Well designed, controlled intervention studies are required to provide definitive information on the species-specific nature of these interactions and on the advantages, disadvantages and optimal timing of de-worming in relation to HIV infection

Addressing Inequities in Urban Health: Do Decision-Makers Have the Data They Need? Report from the Urban Health Data Special Session at International Conference on Urban Health Dhaka 2015

Rapid and uncontrolled urbanisation across low and middle-income countries is leading to ever expanding numbers of urban poor, defined here as slum dwellers and the homeless. It is estimated that 828 million people are currently living in slum conditions. If governments, donors and NGOs are to respond to these growing inequities they need data that adequately represents the needs of the urban poorest as well as others across the socio-economic spectrum. We report on the findings of a special session held at the International Conference on Urban Health, Dhaka 2015. We present an overview of the need for data on urban health for planning and allocating resources to address urban inequities. Such data needs to provide information on differences between urban and rural areas nationally, between and within urban communities. We discuss the limitations of data most commonly available to national and municipality level government, donor and NGO staff. In particular we assess, with reference to the WHO’s Urban HEART tool, the challenges in the design of household surveys in understanding urban health inequities. We then present two novel approaches aimed at improving the information on the health of the urban poorest. The first uses gridded population sampling techniques within the design and implementation of household surveys and the second adapts Urban HEART into a participatory approach which enables slum residents to assess indicators whilst simultaneously planning the response. We argue that if progress is to be made towards inclusive, safe, resilient and sustainable cities, as articulated in Sustainable Development Goal 11, then understanding urban health inequities is a vital pre-requisite to an effective response by governments, donors, NGOs and communities

The effect of curricular and extracurricular activities on university students? entrepreneurial intention and competences

This study examines how the alliance-building process affects the intention to enter into international alliances in the case of small and medium-sized enterprises (SMEs). From a psychological perspective (Perceived Behavioural Control), the authors analyse the alliance-building process as an inhibitor of the international collaboration intention, considering to what extent the experience affects the intention of the partners involved. The study explores these hypotheses based on a sample of 220 Spanish SMEs. The results provide empirical evidence showing that the intention to develop international alliances is negatively affected by the search and the selection process as well as by the negotiation of the agreement, which reduces the intention to establish an international agreement. In addition, the intention is moderated by the experience of the SME manager. Moreover, there is a negative relationship between the extent of the SME manager's international experience and the intention to develop an international alliance

Bringing sustainable agricultural intensification practices and technologies to scale through campaign-based extension approaches: lessons from Africa Soil Health Consortium

Open Access Article; Published online: 19 Sep 2021Sustainable agricultural intensification (SAI) practices have been developed with the aim of increasing agricultural productivity. However, most of them are not achieving their potential because of low adoption, linked to limited extension support to make them known and accessible by end-users. This paper reviews the effectiveness of the Africa Soil Health Consortium (ASHC) extension-based campaigns, contributing knowledge for formulating novel and cost-effective extension approaches. Results show that ASHC campaigns achieved scale of farmer reach and spurred adoption of promoted SAI technologies. Adoption levels for a range of practices were at least 20%, which favourably compares with reported adoption rates for the training and visit extension approach; 1-7% and 11-21% for complex and simple practices respectively. In comparison to a single channel, exposure to multiple communication approaches was associated with higher uptake of promoted practices and technologies, and also increased participation of men, women and youth, by addressing inherent differences in access to, proficiency with, and preferences of communication channels. Success factors associated with ASHC campaigns were; the deployment of multiple and complementary information channels; harnessing public-private partnerships to establish sustainable input supply chains; and development of localized content and fit-for-purpose information materials to facilitate information diffusion
