Do nations have stomachs? Food drink and imagined community in Africa

This paper takes a rhetorical question posed by Ernest Gellner and reframes it to ask whether a sense of national identity can be forged through everyday acts of consumption – in particular, that of food and drink. The article finds value in Benedict Anderson’s conception of the nation as an imagined community, but argues that it makes little sense to privilege the printed word over other forms of consumption. The article goes on to suggest that there have been significant convergences at the level of consumption, but that not all of this has led to reflection about what it means to be a member of the nation. Some lessons are drawn from literatures about music and dress, following which the attention turns to alcoholic drinks and everyday foodstuffs. The history of the consumption of beer and wine in South Africa is used as a case study for convergence in a least likely scenario. The discussion on food observes that while cuisine is not a matter of debate in many African countries, in some countries, like Ethiopia and Senegal, it is taken very seriously indeed. In South Africa, there are ongoing efforts to posit food preferences as something distinctively South African. Although the braai is often discussed in a lighthearted manner, the promotion of a sense of awareness about what all South Africans share in terms of eating habits also has a more serious side to it.Ausgangspunkt des Beitrags ist eine abgewandelte rhetorische Frage von Ernest Gellner. Gefragt wird, ob alltägliche Akte des Konsums, insbesondere Ess- und Trinkgewohnheiten, zur Identifikation mit der eigenen Nation beitragen. Der Beitrag hält Benedict Andersons Konzeption der Nation als Imagined Community für hilfreich, argumentiert aber, dass es wenig Sinn macht, das gedruckte Wort gegenüber anderen Konsumbereichen besonders hervorzuheben. Der Autor beobachtet im Hinblick auf Konsumgewohnheiten signifikante Konvergenzen, die allerdings nicht immer zur Reflexion über nationale Zusammengehörigkeit führen. Er stellt Beiträge zu Musik und Kleidung vor und wendet sich dann der Bedeutung des Konsums alkoholischer Getränke und alltäglicher Nahrungsmittel zu. Mit einer kursorischen Geschichte des Bier- und Weinkonsums in Südafrika greift er einen auf den ersten Blick besonders unwahrscheinlichen Fall von Konvergenz auf. Die nationale Küche ist in afrikanischen Staaten zumeist kein Gegenstand von Debatten, wird in Ländern wie Äthiopien und Senegal allerdings sehr ernst genommen. Auch in Südafrika gibt es Bemühungen, die Bevorzugung bestimmter Lebensmittel als spezifisch südafrikanisch darzustellen; und auch wenn über die in Südafrika gebräuchliche Variante des Grillens (braai) oft eher scherzhaft gesprochen wird, hat doch die Förderung des Bewusstseins, welche Essgewohnheiten alle Südafrikaner miteinander teilen, auch eine ernstere Seite

Cyclical history in the Gambia/Casamance borderlands:Refuge, settlement and Islam from c.1880 to the present

This article begins with a quotation from a local informant highlighting a perception in the Gambia/Casamance borderlands that there is a pattern linking the violence of the later nineteenth century with more recent troubles. It argues that there is some merit in this thesis, which is encapsulated in a concatenation of events: systematic raiding by Fodé Sylla led to the creation of a relatively depopulated colonial border zone which was later filled by Jola immigrants from Buluf to the southeast. In the perception of some, it is these immigrants who attracted the MFDC rebels. Mandinkas and Jolas of Fogny Jabankunda and Narang, and Karoninkas from the islands of Karone have therefore been largely unreceptive to appeals to Casamance nationalism. The article also argues that there are more twisted historical connections. Whereas in the later nineteenth century, the Jolas associated Islam with violent enslavement, they later converted en masse. Their attitude towards Fodé Sylla remained negative, whilst the Mauritanian marabout, Cheikh Mahfoudz, was credited with the introduction of a pacific form of Islam that valorized hard work and legitimated physical migration. This legacy has posed a further barrier to militant nationalism. Islam and violence remain linked, but the signs have been reversed

The Successful Ghana Election of 2008: A Convenient Myth? Ethnicity in Ghana's elections revisited

Ghana’s 2008 elections have been hailed by national and international observers as a model for Africa. This perception has prevailed despite persistent concerns about 'ethnic block voting' and electoral fraud. Electoral malpractice and vote rigging along ethnic lines in Ghana's virtual two-party system could regain a decisive importance as a 'third force' which could tip the balance in future, possibly coming to represent an even more important factor than the smaller opposition parties. Unfortunate diplomatic and technocratic biases in election monitoring, combined with a reluctance on the part of the responsible authorities to investigate, in what appears to be a long history of fraudulent 'ethnic block voting', amounts to a dangerous time bomb of unresolved conflict which could explode in future elections.elections; ethnicity; election observation; informal institutions; impunity; Ghana; Africa;

Cost comparison of orthopaedic fracture pathways using discrete event simulation in a Glasgow hospital

Objective: Healthcare faces the continual challenge of improving outcome whilst aiming to reduce cost. The aim of this study was to determine the micro cost differences of the Glasgow non-operative trauma virtual pathway in comparison to a traditional pathway. Design:  Discrete event simulation was used to model and analyse cost and resource utilisation with an activity based costing approach. Data for a full comparison before the process change was unavailable so we utilised a modelling approach, comparing a Virtual Fracture Clinic (VFC) to a simulated Traditional Fracture Clinic (TFC). Setting:  The orthopaedic unit VFC pathway pioneered at Glasgow Royal Infirmary has attracted significant attention and interest and is the focus of this cost study. Outcome measures: Our study focused exclusively on non-operative trauma patients attending Emergency Department or the minor injuries unit and the subsequent step in the patient pathway. Retrospective studies of patient outcomes as a result of the protocol introductions for specific injuries in association with activity costs from the models.ResultsPatients are satisfied with the new pathway, the information provided and the outcome of their injuries (Evidence Level IV). There was a 65% reduction in the number of first outpatient face-to-face attendances in orthopaedics. In the VFC pathway, the resources required per day were significantly lower for all staff groups (p=<0.001). The overall cost per patient of the VFC pathway was £22.84 (95% CI: 21.74, 23.92) per patient compared with £36.81 (95% CI: 35.65, 37.97) for the TFC pathway.  Conclusions:  Our results give a clearer picture of the cost comparison of the virtual pathway over a wholly traditional face-to-face clinic system. The use of simulation-based stochastic costings in healthcare economic analysis has been limited to date, but this study provides evidence for adoption of this method as a basis for its application in other healthcare settings

Comparing CNN and Human Crafted Features for Human Activity Recognition

Deep learning techniques such as Convolutional Neural Networks (CNNs) have shown good results in activity recognition. One of the advantages of using these methods resides in their ability to generate features automatically. This ability greatly simplifies the task of feature extraction that usually requires domain specific knowledge, especially when using big data where data driven approaches can lead to anti-patterns. Despite the advantage of this approach, very little work has been undertaken on analyzing the quality of extracted features, and more specifically on how model architecture and parameters affect the ability of those features to separate activity classes in the final feature space. This work focuses on identifying the optimal parameters for recognition of simple activities applying this approach on both signals from inertial and audio sensors. The paper provides the following contributions: (i) a comparison of automatically extracted CNN features with gold standard Human Crafted Features (HCF) is given, (ii) a comprehensive analysis on how architecture and model parameters affect separation of target classes in the feature space. Results are evaluated using publicly available datasets. In particular, we achieved a 93.38% F-Score on the UCI-HAR dataset, using 1D CNNs with 3 convolutional layers and 32 kernel size, and a 90.5% F-Score on the DCASE 2017 development dataset, simplified for three classes (indoor, outdoor and vehicle), using 2D CNNs with 2 convolutional layers and a 2x2 kernel size

The successful Ghana election of 2008: a convenient myth?

Ghana's 2008 election has been hailed by national and international observers as a model for Africa. The perception of success has prevailed despite persistent concerns about an inflated voters' register and electoral fraud perpetrated by the two major parties, the NPP and NDC, in their strongholds in the Ashanti and Volta Regions respectively. Electoral malpractice in Ghana's virtual two-party system could acquire a decisive importance as a ‘third force’, representing an even more important factor than the smaller opposition parties. Unfortunate diplomatic and technocratic biases in election monitoring, combined with a reluctance on the part of the responsible authorities to investigate what appears to be a long history of fraudulent voting, amounts to a dangerous time bomb of unresolved conflict which could detonate in future elections

iPTF13beo: The Double-Peaked Light Curve of a Type Ibn Supernova Discovered Shortly after Explosion

We present optical photometric and spectroscopic observations of the Type Ibn (SN 2006jc-like) supernova iPTF13beo. Detected by the intermediate Palomar Transient Factory ~3 hours after the estimated first light, iPTF13beo is the youngest and the most distant (~430 Mpc) Type Ibn event ever observed. The iPTF13beo light curve is consistent with light curves of other Type Ibn SNe and with light curves of fast Type Ic events, but with a slightly faster rise-time of two days. In addition, the iPTF13beo R-band light curve exhibits a double-peak structure separated by ~9 days, not observed before in any Type Ibn SN. A low-resolution spectrum taken during the iPTF13beo rising stage is featureless, while a late-time spectrum obtained during the declining stage exhibits narrow and intermediate-width He I and Si II features with FWHM ~ 2000-5000 km/s and is remarkably similar to the prototypical SN Ibn 2006jc spectrum. We suggest that our observations support a model of a massive star exploding in a dense He-rich circumstellar medium (CSM). A shock breakout in a CSM model requires an eruption releasing a total mass of ~0.1 Msun over a time scale of couple of weeks prior to the SN explosion.Comment: 8 pages, 5 figures, submitted to MNRA

The Future of States in Africa:: Prospects for the Reordering of Space and the Remaking of Bureaucracies

Staaten sind trotz aller Krisen auch in afrikanischen Ländern jene politischen Institutionengefüge, in deren Rahmen Zukunftsvorstellungen verhandelt und zur Grundlage politischer Entscheidungen werden. Der Artikel fasst Diskussionen um afrikanische Staatlichkeit zusammen. Er zeigt an den Beispielen staatlicher Grenzen einerseits, bürokratischen Handelns andererseits auf, welche Beharrlichkeit die Institution des Staates und seine konkreten Formen trotz aller Veränderungen entwickelt haben und wie stark sie Rahmenbedingungen für das Nachdenken über Zukunft und die Verständigung über zukünftige Gesellschaften bilden. Damit zeigt der Artikel auch, wie stark Zukunftsentwürfe von den Mitteln beeinflusst werden, die Gesellschaften sehen, sie durchzusetzen, und von den politischen Institutionen, die Hintergrund ihrer Sozialität bilden
