Participation of women in veld resource utilisation and management: a case study of three villages in Botswana
A conference paper on the participation of women in income-generating community projects in rural Botswana.The arid region of Central Botswana offers few opportunities for rural people to generate income. Arable agriculture routinely fails in 2 out of every 3 years. Poor soils, unpredictable and scanty rainfall, pests, erosion and damage by livestock all reduce the chances of bringing in a successful harvest. Even in years of good rain, crops yields remain low. The most successful use of this arid bushveld region for income generation to date is the production of cattle. However, this activity causes environmental degradation through over-grazing and is almost exclusively dominated by men.
Wildlife utilisation seems to offer possibilities for income generation. But while some communities in Botswana have managed to exploit and profit from their wildlife resources, south-central Botswana is off of the beaten track for tourists. The Department of Wildlife is only beginning to formulate plans for wildlife utilisation in the remote areas.The success of this conference and the publication of these proceedings has been possible through support from the US Agency for International Development (USAID
Unfinished Business: a Review of the Implementation of the Provisions of United Nations General Assembly Resolutions 61/105 and 64/72, Related to the Management of Bottom Fisheries in Areas Beyond National Jurisdiction
In 2006 the General Assembly adopted resolution 61/105, based on a compromise proposal offered by deep-sea fishing nations, which committed States and regional fisheries management organisations [RFMOs] to take specific measures to protect vulnerable marine ecosystems [VMEs] from the adverse impacts of bottom fisheries in the high seas and to ensure the longterm sustainability of deep-sea fish stocks. These measures included conducting impact assessments to determine whether significant adverse impacts[SAIs] to VMEs would occur, managing fisheries to prevent SAIs on VMEs, and closing areas of the high seas to bottom fishing where VMEs are known or likely to occur, unless regulations are in place to prevent SAIs and to manage sustainably deep-sea fish stocks. Based on a review in 2009 of the actions taken by States and RFMOS, the UNGA adoptedresolution 64/72 that reaffirmed resolution 61/105 and strengthened the call for action through committing States, inter alia, to ensure that vessels do not engage in bottom fishing until impact assessments have been carried out and to not authorise bottom fishing activities until the measures in resolutions 64/72 and 61/105 have been adopted andimplemented
Movers and shakers: Granular damping in microgravity
The response of an oscillating granular damper to an initial perturbation is
studied using experiments performed in microgravity and granular dynamics
mulations. High-speed video and image processing techniques are used to extract
experimental data. An inelastic hard sphere model is developed to perform
simulations and the results are in excellent agreement with the experiments.
The granular damper behaves like a frictional damper and a linear decay of the
amplitude is bserved. This is true even for the simulation model, where
friction forces are absent. A simple expression is developed which predicts the
optimal damping conditions for a given amplitude and is independent of the
oscillation frequency and particle inelasticities.Comment: 9 pages, 9 figure
Structuring Joint Action Routines: A Strategy for Facilitating Communication and Language Development in the Classroom
The study of early child language has produced a wealth of new data and conÂcomitant theories over the past decade, and these new perspectives offer important imÂplications to those of us engaged in clinical practice. We have noted elsewhere that this current literature on early child language has specific implications for designing apÂpropriate targets, contexts, and procedures for language therapy (McLean and Snyder-ÂMcLean, 1978; McLean, Snyder-McLean, and Sack, 1983). In this article, we will conÂcentrate on these two latter areas: contexts and procedures for language intervention and, more specifically, on the combination of these elements in the form of structured joint action routines
Biodigital publics: personal genomes as digital media artifacts
The recent proliferation of personal genomics and direct-to-consumer (DTC) genomics has attracted much attention and publicity. Concern around these developments has mainly focused on issues of biomedical regulation and hinged on questions of how people understand genomic information as biomedical and what meaning they make of it. However, this publicity amplifies genome sequences which are also made as internet
texts and, as such, they generate new reading publics. The practices around the generation, circulation and reading of genome scans do not just raise questions about biomedical regulation, they also provide the focus for an exploration of how contemporary public participation in genomics works. These issues around the public features of DTC genomic testing can be pursued through a close examination of the modes of one of the best known providers—23andMe. In fact, genome sequences circulate as digital artefacts and, hence, people are addressed by them. They are read as texts, annotated and written about in browsers, blogs and wikis. This activity also yields content for media coverage which addresses an indefinite public in line with Michael Warner’s conceptualisation of publics. Digital genomic texts promise empowerment, personalisation and community, but this promise may obscure the compliance and proscription associated with these forms. The kinds of interaction here
can be compared to those analysed by Andrew Barry. Direct-to-consumer genetics companies are part of a network providing an infrastructure for genomic reading publics and this network can be mapped and examined to demonstrate the ways in which this formation both exacerbates inequalities and offers possibilities for participation in biodigital culture
Gender agreement on adverbs in Spanish
In this article we explore the exceptional gender agreement of the Spanish adverb mucho
(‘much’), when it modifies comparative adjectives inside DPs that contain a particular type of
noun (as in muchafem mejor intenciónfem, ‘much better intention’). This phenomenon, which we
describe in detail, raises crucial questions both about the mechanisms of agreement and about the
nature of gender in a language such as Spanish. We will argue on the basis of our analysis that
agreement is not semantically motivated, but blindly triggered by certain formal configurations.
We will also argue that –at least in languages such as Spanish– gender information is scattered in
two different positions inside the DP.Peer reviewe
Territorial Tactics: The Socio-spatial Significance of Private Policing Strategies in Cape Town
This paper analyses the policing strategies of private security companies operating in urban space. An existing literature has considered the variety of ways that territory becomes of fundamental importance in the work of public police forces. However, this paper examines territory in the context of private security companies. Drawing on empirical research in Cape Town, it examines how demarcated territories become key subjects in private policing. Private security companies are responsible for a relatively small section of the city, while in contrast the public police ultimately have to see city space as a whole. Hence, private policing strategy becomes one of displacement, especially of so-called undesirables yielding a patchworked public space associated with private enclaves of consumption. The conclusions signal the historical resonances and comparative implications of these political-legal-security dynamics. © 2013 Urban Studies Journal Limited
Efficient generation of Rosa26 knock-in mice using CRISPR/Cas9 in C57BL/6 zygotes
BACKGROUND: The CRISPR/Cas9 system is increasingly used for gene inactivation in mouse zygotes, but homology-directed mutagenesis and use of inbred embryos are less established. In particular, Rosa26 knock-in alleles for the insertion of transgenes in a genomic 'safe harbor' site, have not been produced. Here we applied CRISPR/Cas9 for the knock-in of 8-11 kb inserts into Rosa26 of C57BL/6 zygotes. RESULTS: We found that 10-20 % of live pups derived from microinjected zygotes were founder mutants, without apparent off-target effects, and up to 50 % knock-in embryos were recovered upon coinjection of Cas9 mRNA and protein. Using this approach, we established a new mouse line for the Cre/loxP-dependent expression of Cas9. CONCLUSIONS: Altogether, our protocols and resources support the fast and direct generation of new Rosa26 knock-in alleles and of Cas9-mediated in vivo gene editing in the widely used C57BL/6 inbred strain
