Finding a voice - Nollywood inspired filmmaking practices in Switzerland

Under the name Nollywood a unique video film industry has developed in Nigeria in the last few decades, which now forms one of the world’s biggest entertainment industries. With its focus on stories reflecting „the values, desires and fears” (Haynes 2007: 133) of African viewers and its particular way of production, Nollywood brings „lived practices and its representation together in ways that make the films deeply accessible and entirely familiar to their audience“ (Marston et al. 2007: 57). In doing so, Nollywood shows its spectators new postcolonial forms of performative self‐expression and becomes a point of reference for a wide range of people. However, Nollywood not only excites a large number of viewers inside and outside Nigeria, it also inspires some of them to become active themselves and make their own films. This effect of Nigerian filmmaking can be found in many parts of sub‐Saharan Africa as well as in African diasporas all over the world – including Switzerland (Mooser 2011: 63‐66). As a source of inspiration, Nollywood and its unconventional ways of filmmaking offer African migrants a benchmark that meets their wish to express themselves as minority group in a foreign country. As Appadurai (1996: 53), Ginsburg (2003: 78) and Marks (2000: 21) assume, filmmakers with a migratory background have a specific need to express themselves through media. As minority group members in their country of residence they not only wish to reflect upon their situation within the diaspora and illustrate their everyday struggles as foreigners, but to also express their own views and ideas in order to challenge dominant public opinion (Ginsburg 2003: 78). They attempt to “talk back to the structures of power” (2003: 78) they live in. In this process, their audio-visual works become a means of response and “an answering echo to a previous presentation or representation” (Mitchell 1994: 421). The American art historian Mitchell, therefore, suggests interpreting representation as “the relay mechanism in exchange of power, value, and publicity” (1994: 420). This desire of interacting with the local public has also been expressed during a film project of African, mainly Nigerian, first-generation migrants in Switzerland I am currently partnering in. Several cast and crew members have expressed feelings of being under-represented, even misrepresented, in the dominant Swiss media discourse. In order to create a form of exchange and give themselves a voice, they consequently produce a Nollywood inspired film and wish to present it to the society they live in. My partnership in this on‐going film production (which forms the foundation of my PhD field study) allows me to observe and experience this process. By employing qualitative media anthropological methods and in particular Performance Ethnography, I seek to find out more about the ways African migrants represent themselves as a community through audio‐visual media and the effect the transnational use of Nollywood has on their form of self‐representations as well as the ways they express themselves.

Mosaic pattern of sucrase isomaltase deficiency in two brothers

The pathophysiology of mucosal changes observed in infants with chronic protracted diarrhea is poorly understood. We report on two brothers suffering from a special form of sucrase isomaltase (SI) deficiency. The children presented with weight loss and dyspepsia after sucrose exposition. We performed an H respiration test, which showed a pathologic result in the younger brother. Analysis of the brush border enzyme activities showed low expression of lactase and SI. Immunoelectron microscopy of duodenal biopsies showed an isolated SI deficiency in a mosaic pattern [e.g., 42% (14%) crypt enterocytes and 64% (59%) villus enterocytes with decreased amounts of SI on microvilli], whereas lactase and aminopeptidase n (ApN) were present at the apical membrane of all cells in a normal range. The SI mosaic pattern of these patients shows that the enterocytes contain low amounts of SI on the apical membrane but express normal quantities of other disaccharidases. These findings suggest the existence of different clonal expressions or specific (posttranslational) mechanisms of postGolgi transportation for individual brush border enzymes. It remains unresolved whether the mosaic distribution is part of a normal maturation process or caused by a lack of an overall control mechanism in the expression of brush border hydrolases.

Reaction of Copper(II) Chloroacetate with Pyrazole. Synthesis of a One-Dimensional Coordination Polymer and Unexpected Dehydrochlorination Reaction

The reaction of copper(II) chloroacetate (1d) with pyrazole (Hpz) mainly yielded the mononuclear compound [Cu(μ-ClCH2COO)2(Hpz)2] (2m), which self-assembled generating a one-dimensional coordination polymer. Moreover, the concomitant isolation of the tetranuclear [{Cu2(μ-pz)(μ-OCH2COO)(Hpz)(MeOH)}2(μ-ClCH2COO)2] (3t) and hexanuclear [{Cu3(μ3-OH)(μ-pz)3(Hpz)2}2(μ-ClCH2COO)2](Cl)2 (4h) species evidenced the occurrence of a peculiar, previously unreported, dehydrochlorination reaction and the formation of the trinuclear triangular moiety [Cu3(μ3-OH)(μ-pz)3]. Theoretical calculations based on density functional theory including solvation effects indicate a possible pathway for the formation of 3t. Interestingly, besides the energy minimum corresponding to 3t, a further relative energy minimum is found for a species which can be considered a possible reaction intermediate.

Interaction of the Trinuclear Triangular Secondary Building Unit [Cu 3 (μ 3 -OH)(μ-pz) 3 ] 2+ with 4,4′-Bipyridine. Structural Characterizations of New Coordination Polymers and Hexanuclear Cu II Clusters. 2°

By reacting 4,4′-bipyridine (bpy) with selected trinuclear triangular CuII complexes, [Cu3(μ3-OH)(μ-pz)3(RCOO)2(LL′)] [pz = pyrazolate anion; R = CH3, CH3CH2, CH2═CH, CH2═C(CH3); L, L′ = Hpz, H2O, MeOH] in MeOH, the substitution of monotopic ligands by ditopic bpy was observed. Depending on the stoichiometric reaction ratios, different compounds were isolated and structurally characterized. One- and two-dimensional coordination polymers (CPs), as well as two hexanuclear CuII clusters were identified. One of the hexanuclear clusters self-assembles into a supramolecular three-dimensional structure, and its crystal packing shows the presence of two intersecting channels, one of which is almost completely occupied by guest bpy, while in the second one guest water molecules are present. This compound also shows a reversible, thermally induced, single-crystal-to-single-crystal transition.

Phyllotaxis — a new chapter in an old tale about beauty and magic numbers

Phyllotaxis, the regular arrangement of leaves and flowers around the stem, is one of the most fascinating patterning phenomena in biology. Numerous theoretical models, that are based on biochemical, biophysical and other principles, have been proposed to explain the development of the patterns. Recently, auxin has been identified as the inducer of organ formation. An emerging model for phyllotaxis states that polar auxin transport in the plant apex generates local peaks in auxin concentration that determine the site of organ formation and thereby the different phyllotactic patterns found in nature. The PIN proteins play a primary role in auxin transport. These proteins are localized in a polar fashion, reflecting the directionality of polar auxin transport. Recent evidence shows that most aspects of phyllotaxis can be explained by the expression pattern and the dynamic subcellular localization of PIN1.

Biochemical MRI predicts hip osteoarthritis in an experimental ovine femoroacetabular impingement model

BACKGROUND Cam-type femoroacetabular impingement (FAI) resulting from an abnormal nonspherical femoral head shape leads to chondrolabral damage and is considered a cause of early osteoarthritis. A previously developed experimental ovine FAI model induces a cam-type impingement that results in localized chondrolabral damage, replicating the patterns found in the human hip. Biochemical MRI modalities such as T2 and T2* may allow for evaluation of the cartilage biochemistry long before cartilage loss occurs and, for that reason, may be a worthwhile avenue of inquiry. QUESTIONS/PURPOSES We asked: (1) Does the histological grading of degenerated cartilage correlate with T2 or T2* values in this ovine FAI model? (2) How accurately can zones of degenerated cartilage be predicted with T2 or T2* MRI in this model? METHODS A cam-type FAI was induced in eight Swiss alpine sheep by performing a closing wedge intertrochanteric varus osteotomy. After ambulation of 10 to 14 weeks, the sheep were euthanized and a 3-T MRI of the hip was performed. T2 and T2* values were measured at six locations on the acetabulum and compared with the histological damage pattern using the Mankin score. This is an established histological scoring system to quantify cartilage degeneration. Both T2 and T2* values are determined by cartilage water content and its collagen fiber network. Of those, the T2* mapping is a more modern sequence with technical advantages (eg, shorter acquisition time). Correlation of the Mankin score and the T2 and T2* values, respectively, was evaluated using the Spearman's rank correlation coefficient. We used a hierarchical cluster analysis to calculate the positive and negative predictive values of T2 and T2* to predict advanced cartilage degeneration (Mankin ≥ 3). RESULTS We found a negative correlation between the Mankin score and both the T2 (p < 0.001, r = -0.79) and T2* values (p < 0.001, r = -0.90). For the T2 MRI technique, we found a positive predictive value of 100% (95% confidence interval [CI], 79%-100%) and a negative predictive value of 84% (95% CI, 67%-95%). For the T2* technique, we found a positive predictive value of 100% (95% CI, 79%-100%) and a negative predictive value of 94% (95% CI, 79%-99%). CONCLUSIONS T2 and T2* MRI modalities can reliably detect early cartilage degeneration in the experimental ovine FAI model. CLINICAL RELEVANCE T2 and T2* MRI modalities have the potential to allow for monitoring the natural course of osteoarthrosis noninvasively and to evaluate the results of surgical treatments targeted to joint preservation.

Collecting the Painted Netherlands: The Art Collection of Ernest of Austria in Brussels

The (art) collection of Archduke Ernest of Austria (1553-1595) is widely unknown when it comes to early-modern Habsburg collections. Ernest, younger brother of Emperor Rudolf II (b. 1552) and educated at the Madrid court, was appointed Governor-General of the Netherlands by King Philip II of Spain, his uncle, in summer 1593. Ernest relocated his court from Vienna to Brussels in early 1594 and was welcomed there with lavish festivities: the traditional Blijde Inkomst, Joyous Entry, of the new sovereign. Unfortunately, the archduke died in February 1595 after residing in Brussels for a mere thirteen months. This investigation aims to shed new light on the archduke and his short-lived collecting ambitions in the Low Countries, taking into account that he had the mercantile and artistic metropolis Antwerp in his immediate reach. I argue, that his collecting ambitions can be traced back to one specific occasion: Ernest’s Joyous Entry into Antwerp in June 1594. There the archduke received a series of six paintings of Pieter Bruegel the Elder (1525/30-1569) known as The Months (painted in 1565), hanging today in separate locations in Vienna, New York and Prague. These works of art triggered Ernest’s collecting ambitions and prompted him to focus mainly on works of art and artefacts manufactured at or traded within the Netherlands during the last eight months of his lifetime. Additionally, it will be shown that the archduke was inspired by the paintings’ motifs and therefore concentrated on acquiring works of art depicting nature and landscape scenes from the 1560s and 1590s. On the basis of the archduke’s recently published account book (Kassabuch) and of the partially published inventory of his belongings, it becomes clear that Ernest of Austria must be seen in line with the better-known Habsburg collectors and that his specific collection of “the painted Netherlands” can be linked directly to his self-fashioning as a rightful sovereign of the Low Countries.

Campaign strategies at the Swiss National Elections 2015: Nationalization, Coordination, and Personalization

This research note examines parties’ campaign strategies in the 2015 Swiss elections. We base our analyses on a collection of more than 5000 party advertisements, which were published in the forefront of the national elections in more than 50 daily and weekly national and cantonal print media. By comparing the amount of party and candidate ads, as well as the content and nature of the political advertisements, we explore the degree of professionalization of electoral campaigns in the most recent federal elections in terms of nationalization, coordination and personalization. First results show that although national campaign coordination exists, Swiss elections are to a considerable extent still cantonal and personal affairs.

Organisation of the equine immunoglobulin constant heavy chain genes. II. Equine cgamma genes.

The number of immunoglobulin G constant heavy chain genes (cgamma genes) varies broadly among mammalian species, reflecting structural and functional differences between expressed immunoglobulin G (IgG) isotypes and allotypes. Up to now equine IgG isotypes have been defined only at the biochemical and serological level. It is still not clear how many IgG isotypes exist in horses and whether there are any allotypes. Here, we describe the isolation and characterisation of equine cgamma genes. An equine genomic lambda phage library was screened with a human cgamma4 probe. Cross-hybridising equine cgamma sequences were cloned twice and characterised by restriction mapping with the human cgamma4 and a murine sgamma1 probe. Genomic equine DNA probes for both, cgamma genes and corresponding switch regions (sgamma), were isolated and used for a more detailed BamHI restriction analysis, comparing genomic DNA of various horses. This analysis reveals the existence of at least five, or probably six cgamma genes in the equine haploid genome. Beside the porcine system, this is the highest number of cgamma genes described for any mammalian species. Moreover, for two of these cgamma genes, BamHI restriction fragment length polymorphism became evident.
