The process of moving to a fully digital microscopy laboratory requires changes in instrumentation, computing hardware, computing software, data storage systems, and data networks, as well as in the operating procedures of each facility. Moving from analog to digital systems in the microscopy laboratory is similar to the instrumentation projects being undertaken in many scientific labs. A central problem of any of these projects is to create the best combination of hardware and software to effectively control the parameters of data collection and then to actually acquire data from the instrument. This problem is particularly acute for the microscopist who wishes to "digitize" the operation of a transmission or scanning electron microscope. Although the basic physics of each type of instrument and the type of data (images & spectra) generated by each are very similar, each manufacturer approaches automation differently. The communications interfaces vary as well as the command language used to control the instrument.

Britain's short-lived Province of Senegambia (1765–1783) was part of an expansion effort in the region driven by a desire to secure access to the gum trade of the Senegal river. Drawing on Britain's knowledge of France's dealings with the Upper-Senegal region it was complemented by the adoption of French cartography, edited to illustrate a new colonial identity. It is argued here that there was an additional motive of developing closer contact with the African interior. This pre-dates the establishment of the African Association in 1788 and its subsequent and better-known expeditions to the River Niger. In contrast to the French, however, the British struggled to engage with the region. This paper approaches the topic from a perspective of cartographic history. It highlights Thomas Jeffery's map of ‘Senegambia Proper’ (1768), copied from Jean Baptiste Bourguingnon d'Anville's ’Carte Particuliére de la Côte Occidentale de l'Afrique' (1751) and illustrative of several obstacles facing both British map-making and colonial expansion in mid-eighteenth century Africa. It is argued that the later enquiries and map-making activities of the African Association, which were hoped to lead to the colonisation of West Africa, built upon these experiences of failure in Senegambia.

Women’s access to and control over productive resources, including land, has increasingly been recognized in global discussions as a key factor in reducing poverty, ensuring food security and promoting gender equality. Indeed, this argument has been widely accepted by both feminists and development theorists since the 1980s. Based on qualitative research with 50 purposively selected men and women, this study explored the complexity of women’s access to and control over land within a specific relationship of contestations, negotiations, and manipulations with men. Data were analyzed using thematic analysis. While theoretically, participants showed that women’s [secure] access to and control over land has beneficial consequences to women themselves, households and the community at large, in principle, women's access and control status was premised in the traditional framework which largely deprives women, equal access and/or control over the land. The study indicates that even though land is the most revered resource and indeed, the dominant source of income for the rural poor, especially women, gender-erected discrimination and exclusion lie at the heart of many rural women in gaining access to land. This study argues that women's weak access rights and control over land continue to perpetuate the feminization of gender inequality–while men were reported to possess primary access and control over land as the heads of households, women were argued to have secondary rights due to their ‘stranger statuses’ in their husbands’ families. Overall, the degree of access to land among women was reported to be situated within two broad contexts–marriage and inheritance.
