G74-188 Amaryllis Culture

The hybrid amaryllis (Hippeastrum) is a tender bulb easily grown in pots. Amaryllis is prized for its huge showy flowers ranging from scarlet or crimson to white in color, and often striped or mottled. Amaryllis can be grown outdoors throughout the year in mild climates, but must be grown indoors in Nebraska except during the warm summer months. Amaryllis is prized for its huge showy flowers ranging from scarlet or crimson to white in color, and often striped or mottled. Most amaryllis are Dutch or African hybrids selected for flower size, color and ease of forcing. The usual flowering season is from February to April. The foliage grows during spring and summer, ripening early in the fall if temperatures are low and the soil is allowed to dry out. The bulb normally remains dormant until late winter (December or January)

ICT adoption and development of E-business among SMEs in South Africa

Objectives: This paper examines ICT adoption among small hotel establishments in South Africa. The paper identifies the key ICT adoption attributes and explains how these influence ICT adoption and development of e-business among these typical SMEs in South Africa. Prior Work: The paper draws and builds on several studies on ICT adoption in small firms (Gibbs et al., 2007; Beckinsale and Ram, 2006; Zappala and Gray, 2006; Manueli et al., 2007). Notably, the paper mainly draws from the Gibbs et al. (2007) model which identifies and integrates the key ICT adoption factors that include government; environmental attributes; owner (managerial) attributes; organisational attributes; adoption attributes and social networks. Approach: This qualitative research takes a multiple case study approach highlighting the experiences of small hotel establishments in South Africa. Semi-structured interviews, observation and document analyses are used to collect data from a total of 3 case studies theoretically sampled from two locations in Johannesburg. The underlying technique in the analytical and interpretative process within the multiple case study methodology is that of epistemological bootstrapping (Archer, 1988). Results: The findings suggest internet; websites; fixed-line and mobile phone networks as the most common technologies adopted by SMEs to support their e-business operations. The results also suggest both formal and informal networks as important for ICT adoption. These are key sources of information, technology, social and business support. In addition, financial and owner manager support, including personal skills and experience are also crucial in the adoption of ICT. Power outage is identified as a major barrier across the three case studies. Government intervention is largely indirect and crucial in areas such as setting up of national ICT policy; infrastructure; dissemination of information; facilitating public-private partnerships; capacity building and power supply. Implications: The paper highlights ICT adoption and the distinctive and behavioural characteristics of SMEs operating small hotel business in South Africa. Potentially, other sectors and, SMEs in general may benefit from these insights which may also be useful to policy-makers in terms of effective policy reviews, implementation and support strategies for SMEs. Value: Although this paper only presents the findings based on SMEs in South Africa, the original doctoral project also included case studies from Botswana and Zimbabwe. The findings contribute to literature on ICT adoption among SMEs in general, but more specifically bring new insights to this area of study in developing nations within SADC. In addition, the research framework was applied within different geographical, economic, political and social contexts of the SADC countries and provided insights which suggested it was a useful framework for undertaking this research in southern Africa. Future research involving more SADC countries and other SME sectors would bring more detailed insights into ICT adoption at regional level

Advancing reproducible research by publishing R markdown notebooks as interactive sandboxes using the learnr package

Various R packages and best practices have played a pivotal role to promote the Findability, Accessibility, Interoperability, and Reuse (FAIR) principles of open science. For example, (1) well-documented R scripts and notebooks with rich narratives are deposited at a trusted data centre, (2) R Markdown interactive notebooks can be run on-demand as a web service, and (3) R Shiny web apps provide nice user interfaces to explore research outputs. However, notebooks require users to go through the entire analysis, while Shiny apps do not expose the underlying code and require extra work for UI design. We propose using the learnr package to expose certain code chunks in R Markdown so that users can readily experiment with them in guided, editable, isolated, executable, and resettable code sandboxes. Our approach does not replace the existing use of notebooks and Shiny apps, but it adds another level of abstraction between them to promote reproducible science
