Counting as citizens: Recognition of the Nubians in the 2009 Kenyan census

This article uses the case of the Nubians in Kenya as an ethnic minority, and the 2009 Kenyan census as a particular form of recognition, to engage in a particular aspect of the debates surrounding the politics of recognition: the perceived competitive nature of the relationship between national and subnational groups, in this case ethnic groups. Using data obtained during a 6-month qualitative study conducted over the census period, this paper evaluates the response of some members of the Nubian community to their participation in the census, focusing on its most controversial question, ‘What tribe are you?’ The article concludes that the dynamic between ethnic and national identities and allegiances, when the former are recognized, can be the site of agency, participatory citizenship, and therefore also democratic equality, action and interaction

Indigeneity and Kenya’s Nubians: seeking equality in difference or sameness?

ABSTRACTRecent studies of indigeneity in Africa have highlighted the problematic nature of the concept in a continent where it is difficult to determine which groups have temporal priority in a given location. These studies have suggested, with varying degrees of criticism, that indigeneity in Africa is a strategic identity deployed to attain a special status and associated benefits, often to remedy past harms. This article agrees that indigeneity is an act of positioning, but suggests that in the Kenyan context it can be deployed in another way as well, that is, as an act that seeksequalrather thanspecialpositioning within the dominant population. In this case indigeneity is not a special ‘slot’ but rather the norm. The article illustrates this by drawing on research with the Nubian community of Nairobi who seek to shed their ethnic stranger status and instead position themselves as indigenous to Nairobi in order to access the same quality of citizenship as that enjoyed by Kenya's ‘42 tribes’.</jats:p

Evaluating the impact of binary parameter uncertainty on stellar population properties

Binary stars have been shown to have a substantial impact on the integrated light of stellar populations, particularly at low metallicity and early ages - conditions prevalent in the distant Universe. But the fraction of stars in stellar multiples as a function of mass, their likely initial periods and distribution of mass ratios are all known empirically from observations only in the local Universe. Each has associated uncertainties. We explore the impact of these uncertainties in binary parameters on the properties of integrated stellar populations, considering which properties and timescales are most susceptible to uncertainty introduced by binary fractions and whether observations of the integrated light might be sufficient to determine binary parameters. We conclude that the effects of uncertainty in the empirical binary parameter distributions are likely smaller than those introduced by metallicity and stellar population age uncertainties for observational data. We identify emission in the He II 1640Å emission line and continuum colour in the ultraviolet-optical as potential indicators of a high mass binary presence, although poorly constrained metallicity, dust extinction and degeneracies in plausible star formation history are likely to swamp any measurable signal

Binary population synthesis models for core-collapse gamma-ray burst progenitors

Long-duration gamma-ray bursts (GRBs) are understood to be the final fate for a subset of massive, stripped envelope, rapidly rotating stars. Beyond this, our knowledge of the progenitor systems is limited. Using the BPASS (Binary Population and Spectral Synthesis) stellar evolution models, we investigate the possibility that some massive stars in binaries can maintain the angular momentum required for jet production, while still loosing their outer envelope through winds or binary interactions. We find that a total hydrogen mass of less than 0.0005 Msun and a helium ejecta mass fraction of less than 0.20 provide the best thresholds for the supernova type II/Ibc and Ib/Ic divisions respectively. Tidal interactions in binaries are accounted for by applying a tidal algorithm to post-process the stellar evolution models output by BPASS. We show that the observed volumetric gamma-ray burst rate evolution can be recreated using two distinct pathways and plausible distributions for burst parameters. In the first pathway, stars are spun up by mass accretion into a quasi-homogeneous state. In the second, tides maintain rotation where otherwise the star would spin down. Both lead to type Ic supernova progenitors, and a metallicity distribution consistent with the GRB host galaxy population. The inferred core angular momentum threshold for jet production is consistent with theoretical requirements for collapsars, given the assumptions made in our model. We can therefore reproduce several aspects of core collapse supernova/GRB observation and theory simultaneously. We discuss the predicted observable properties of GRB progenitors and their surviving companions

Contextualizing the business responsibility to respect: How much is lost in translation?

As the work of the UN Special Representative (UNSR) for business and human rights moves towards its conclusion in mid-2011, the core principles of the UNSR&rsquo;s &lsquo;responsibility to respect&rsquo; framework have received widespread endorsement from businesses, NGOs and governments. The translation of these general principles into specific obligations governing business activity will need to differ according to context. The reasons why overarching regulatory principles can get &lsquo;lost in translation&rsquo; when applied in practice have important implications for understanding how the UNSR&rsquo;s responsibility to respect framework can be meaningfully implemented across widely varying regulatory contexts. The central goal of this chapter is to understand why and under what conditions this loss is likely to arise, and how regulatory standards for business and human rights might be designed to enable the responsibility to respect principle to be applied in context-sensitive ways, without losing regulatory force

Census politics in deeply divided societies

Population censuses in societies that are deeply divided along ethnic, religious or linguistic lines can be sensitive affairs – particularly where political settlements seek to maintain peace through the proportional sharing of power between groups. This brief sets out some key findings from a research project investigating the relationship between census politics and the design of political institutions in Bosnia and Herzegovina, Kenya, Lebanon and Northern Ireland

Plasmon resonances of highly doped two-dimensional MoS2

The exhibition of plasmon resonances in two-dimensional (2D) semiconductor compounds is desirable for many applications. Here, by electrochemically intercalating lithium into 2D molybdenum disulfide (MoS2) nanoflakes, plasmon resonances in the visible and near UV wavelength ranges are achieved. These plasmon resonances are controlled by the high doping level of the nanoflakes after the intercalation, producing two distinct resonance peak areas based on the crystal arrangements. The system is also benchmarked for biosensing using bovine serum albumin. This work provides a foundation for developing future 2D MoS2 based biological and optical units
