This article parts from an interdisciplinary point of view. Its main interest lies in the rich and complex interaction between the literary text and the image. These relations are understood as a “reciprocal illumination between the arts”, according to a publication of Oskar Walzel (Berlin, 1917). It will first investigate two historical landmarks in relation to literature and the image: first, the social differentiation around 1800 and its imposition of a purely textual literature and second, the avant-garde with its intense interaction between the various forms of artistic communication. The paper will then approach two contemporary examples of novels which combine visual and textual material.
' The United Nations-organised plebiscite on 11 February 1961 was one of the most significant events in the history of the southern and northern parts of the British-administered trust territory in Cameroon. John Percival was sent by the then Colonial Office as part of the team to oversee the process. This book captures the story of the plebiscite in all its dimensions and intricacies and celebrates the author's admiration for things African through a series of reminiscences of what life was like in the 1960s, both for the Africans themselves and for John Percival as a very young man. The complex story is also a series of reflections about the effect of the modern world on Africa. It is a thorough, insightful, rich and enlightening first-hand source on a political landmark that has never been told before in this way. In a vivid style with a great sense of humour, Percival's witty, cogent, eyewitness and active-participant account deconstructs the rumours and misrepresentations about the February 1961 Plebiscite which was a prelude to reunification and to the present day politics of 'belonging' in Cameroon. ''One of the major merits of this book is to provide us with a deeper insight into the role of those actors who have never been the subject of plebiscite studies, namely the Plebiscite Supervisory Officers.'' - Piet Konings, African Studies Centre, Leiden, The Netherlands John Percival-Anthropologist, Writer, Television Broadcaster of many innovative BBC series on the environment, history and anthropology. As a young graduate he was recruited and sent to serve in the Southern Cameroons as a Plesbiscite Supervisory Officer in 1961. He died in 2005 after a recent return visit to Cameroon with Nigel Wenban-Smith who writes an epilogue. This posthumous memoir has been edited by his wife, Lalage Neal.'
We perform a detailed study of the adjoint static potential in the pseudoparticle approach, which is a model for SU(2) Yang-Mills theory. We find agreement with the Casimir scaling hypothesis and there is clear evidence for string breaking. At the same time the potential in the fundamental representation is linear for large separations. Our results are in qualitative agreement with results from lattice computations.
Naturalness is one of the most important criteria in nature conservation. This paper examines the fundamental concepts underlying the definition and assessment of naturalness. Its role in nature conservation and forest management under conditions of global change is also discussed. The degree of naturalness may be defined in ordinal classes. The “static” concept of the potential natural vegetation (pnV), developed in the 1950ies, is mostly used as the reference state. In other cases, its reversed concept, the hemeroby (degree of articifiality) is assessed, based on the intensity and frequency of human impacts. Since the 1970ies, more attention has been given to natural dynamics than in earlier approaches, e.g. in forest succession models. At the end of the 1980ies, the previous importance was increasingly stressed of natural browsing by large herbivores and the role of predators. These large herbivors are extinct today in most cultural European landscapes. It is assumed, that they open up the canopy, and create park-like forest structures which contain a diversity of habitats for other types of organism (birds, insects). Changed and permanently changing environments and altering patterns of competition between species continue to modify natural processes today. Some of the more conspicuous effects are the extinction of native species and immigration of species to new regions. Long-lived ecosystems like forests are however not able to adapt quickly to such changes and may be unable to find a new balance with the environment. Today, such changes occur very rapidly, and are reducing the original naturalness of ecosystems. Because of this, the criterion “naturalness” must be downweighted. Conversely, more importance should be attached to other criteria: particularly originality (= original naturalness) and restorability. Forestry is contributing to this accelerated change of biocoenoses by increasing disturbances and introducing exotic tree species. Naturalisation of some exotic tree species modifies the natural processes and creates a “new allochthonous naturalness”. Because of this, forest planning should try to preserve or restore stands with attributes of the “original forest”. Exotic species should not be planted, or only in a very restricted way.
The Barn
(2008)
As a veteran playwright and actor, Kwo Victor Elame Musinga is more than just a pioneer in popular theatre. His simple but profound messages demonstrate a depth of understanding and insight into human nature and the nature of society. The texts he crafts are universal and timeless in their content and appeal, even as the themes and situations that inspire them are localized in specific places, experiences and histories. The Barn is a collection of three topical plays. Njema captures the predicament of love in a context where innocence and trust are preyed upon by deceit, dishonesty, promiscuity, waywardness, callous indifference to human life, the reckless abandon of parental authority and wisdom by youth in a hurry to celebrate sexuality, irresponsible manhood with or without the connivance of girls/women, and HIV/AIDS and its terror. Invitation to God addresses elitism and fair-weather friendship even among believers. In Moka, the theme of friendship is explored through the simple act of dishonesty and greed, especially to those with whom one should be nothing but virtuous, open, generous and kind. In these plays Kwo Victor Elame Musinga explores the virtues of being human, while addressing the dark side of humanity.
The bee fauna of the Greater Puerto Rico area was studied. A review of the previous relevant studies is presented. An annotated catalog and information about the origin and distributional patterns are also provided. Thirty-nine species of bees occur in Puerto Rico and adjacent islands. This fauna is composed of four elements: exclusive Puerto Rican endemics (26.5%); Antillean endemics occurring on multiple islands (76.5%); continental species that have also colonized the Antilles (23.5%); and species introduced through human activity (12.8%). The bee fauna was both low in its diversity and showed the highest level of disharmony in relation to other faunas of the Greater Antilles. A lectotype is here designated for Agapostemon krugii Wolcott, 1936.
Cellular metabolism can be envisaged by fluorescence lifetime imaging of fluorophores sensitive to specific intracellular factors such as [H+], [Ca2+], [O2], membrane potential, temperature, polarity of the probe environment, and alterations in the conformation and interactions of macromolecules. Lifetime measurements of the probes allow the quantitative determination of the intracellular factors. Fluorescence microscopy taking advantage of time-correlated single photon counting is a novel method that outperforms all other techniques with its single photon sensitivity and picoseconds time resolution. In this work, a time- and space-correlated single photon counting system was established to investigate the behavior of 2-(4-(dimethylamino)styryl)-1-methylpyridinium iodide (DASPMI) in living cells. DASPMI is known to selectively stain mitochondria in living cells. The uptake and fluorescence intensity of DASPMI in mitochondria is a dynamic measure of membrane potential. Hence, an endeavour was made to elucidate the mechanism of DASPMI fluorescence by obtaining spectrally-resolved fluorescence decays in different solvents. A bi-exponential decay model was sufficient to globally describe the wavelength dependent fluorescence in ethanol and chloroform. While in glycerol, a three-exponential decay model was necessary for global analysis. In the polar low-viscous solvent water, a mono-exponential decay model fitted the decay data. The sensitivity of DASPMI fluorescence to solvent viscosity was analysed using various proportions of glycerol/ethanol mixtures. The lifetimes were found to increase with increasing solvent viscosity. The negative amplitudes of the short lifetime component found in chloroform and glycerol at the longer wavelengths validated the formation of new excited state species from the initially excited state. Time-resolved emission spectra in chloroform and glycerol showed a biphasic increase of spectral width and emission maxima. The spectral width had an initial fast increase within 150 ps and a near constant thereafter. A two-state model based on solvation of the initially excited state and further formation of TICT state has been proposed to explain the excited state kinetics and has been substantiated by the de-composition of time-resolved spectra. The knowledge of DASPMI photophysics in a variety of solvents now provides the means of deducing complex physiological parameters of mitochondria from its behavior in living cells. Spatially-resolved fluorescence decays from single mitochondria or only very few organelles of XTH2 cells signified distinctive three-exponential decay kinetics of viscous environment. Based on DASPMI photophysics in a variety of solvents, these lifetimes have been attributed to the fluorescence from locally excited state (LE), intramolecular charge transfer state (ICT) and twisted intramolecular charge transfer (TICT) state. A considerable variation in lifetime among mitochondria of different morphology and within single cell was evident corresponding to the high physiological variations within single cells. Considerable shortening of the short lifetime component (τ1) under high membrane potential condition, such as in the presence of ATP and/or substrate, was similar to quenching and dramatic decrease of lifetime in polar solvents. Under these conditions τ2 and τ3 increased with decreasing contribution. Upon treatment with ionophore nigericin, hyperpolarization of mitochondria resulted in remarkable shortening of τ1 from 159 ps to 38 ps. Inhibiting respiration by cyanide resulted in notable increase of mean lifetime and decrease of mitochondrial fluorescence. Increase of DASPMI fluorescence on conditions elevating mitochondrial membrane potential has been attributed to uptake according Nernst distributions, to de-localisation of π electrons, quenching processes of the methyl pyridinium moiety and restricted torsional dynamics at the mitochondrial inner membrane. Accordingly, determination of anisotropy in DASPMI stained mitochondria in living XTH2 cells, revealed dependence of anisotropy on membrane potential. Such changes in anisotropy attributed to restriction of the torsional dynamics about the flexible single bonds neighboring the olefinic double bond revealed the previously known sub-mitochondrial zones with higher membrane potential along its length. Membrane-potential-dependent changes in anisotropy have further been demonstrated in senescent chick embryo fibroblasts. In conclusion, spectroscopic observations of excited-state kinetics of DASPMI in solvents and its behavior in living cells had revealed for the first time its localisation, mechanism of voltage sensitive fluorescence and its membrane-potential-dependent anisotropy in living cells. The simultaneous dependence of DASPMI photophysics on mitochondrial inner membrane viscosity and transmembrane potential has been highlighted.
A list of all liverworts and mosses reported from the Maltese Islands with references has been compiled from the literature, which includes 23 species of liverworts and hornworts as well as 96 taxa of mosses. The list is completed by the results of a bryological fieldtrip in March 2008. During this trip, 14 species of liverworts and 40 species of mosses were collected, of which Cephaloziella baumgartneri, Didymodon luridus, Fissidens gracilifolius, Fossombronia echinata, Funaria pulchella, Riccia cavernosa and Weissia fallax are new to Malta. This raises the number of species known from the Maltese Islands to 23 horn- and liverworts and 100 mosses.
This book richly documents the battles fought by the Anglophone community in Cameroon to safeguard the General Certificate of Education (GCE), a symbol of their cherished colonial heritage from Britain, from attempts by agents of the Ministry of National Education to subvert it. These battles opposed a mobilised and determined Anglophone civil society against numerous machinations by successive Francophone-dominated governments to destroy their much prided educational system in the name of 'national integration'. When Southern Cameroonians re-united with La R?publique du Cameroun in 1961, they claimed that they were bringing into the union 'a fine education system' from which their Francophone compatriots could borrow. Instead, they found themselves battling for decades to save their way of life. Central to their concerns and survival as a community is an urgent need for cultural recognition and representation, of which an educational system free of corruption and trivialisation through politicisation is a key component.
The Chanukah omission
(2008)
In a charter issued on 5 May 1513, the mayor and city council of the city of Freiburg/Breisgau reported that several citizens wanted to be allowed to establish a bruderschaft der sengerye, a confraternity of singing. “God, the almighty, would be praised thereby, the souls would be consoled, and all men listening to the concerts would be kept from blasphemy, gaming and other secular vices” (“gott der allmechtig [würde] dardurch gelopt, die selen getröst und die menschen zu zyten, so sy dem gesang zuhorten, von gotslesterung, ouch vom spyl vnd anderer weltlicher uppigkeyt gezogen”). Considering not least the “positive effects on the pour souls” (“guettaeten, so den armen selen dardurch nachgeschechen mocht”), the request was allowed. But the petitioners had to establish their bruderschaft in exactly the form that is described in detail in the regulations (ordnung) added to the request and cited “word for word” (“von wort zu wort”) in 17 articles in the foundation charter of the confraternity.
Hong Kong’s Linked Exchange Rate System (LERS) has been in operation for twenty-five years during which time many other fixed exchange rate systems have succumbed to shocks and/or speculative attacks. This fact alone suggests that the LERS is a robust system which enjoys a large measure of credibility in financial markets. This paper intends to investigate whether this is indeed the case, and whether it has been the case throughout its 25-year history. In particular we will use the tools of modern finance to extract information from financial asset prices about market expectations that are related to the credibility of the LERS. The main focus is on how market participants ‘judged’ the various changes made to the LERS, such as the ‘seven technical measures’ introduced in September 1998 and the ‘three refinements’ made in May 2005. These changes have been characterizes as making the system less discretionary over time, and we hypothesize that they have also made it more credible as revealed in the prices of exchange rate related asset prices. We also investigate the relationship between interest rates and exchange rates in the current system in light of modern models of target-zone exchange rate systems. We will examine whether the intramarginal intervention in November 2007 changed the dynamic properties of the exchange rate as suggested by such models.
Ribosome biogenesis in eukaryotes requires the participation of a large number of ribosome assembly factors. The highly conserved eukaryotic nucleolar protein Nep1 has an essential but unknown function in 18S rRNA processing and ribosome biogenesis. In Saccharomyces cerevisiae the malfunction of a temperature-sensitive Nep1 protein (nep1-1ts) was suppressed by the addition of S-adenosylmethionine (SAM). This suggests the participation of Nep1 in a methyltransferase reaction during ribosome biogenesis. In addition, yeast Nep1 binds to a 6-nt RNA-binding motif also found in 18S rRNA and facilitates the incorporation of ribosomal protein Rps19 during the formation of pre-ribosomes. Here, we present the X-ray structure of the Nep1 homolog from the archaebacterium Methanocaldococcus jannaschii in its free form (2.2 Å resolution) and bound to the S-adenosylmethionine analog S-adenosylhomocysteine (SAH, 2.15 Å resolution) and the antibiotic and general methyltransferase inhibitor sinefungin (2.25 Å resolution). The structure reveals a fold which is very similar to the conserved core fold of the SPOUT-class methyltransferases but contains a novel extension of this common core fold. SAH and sinefungin bind to Nep1 at a preformed binding site that is topologically equivalent to the cofactor-binding site in other SPOUT-class methyltransferases. Therefore, our structures together with previous genetic data suggest that Nep1 is a genuine rRNA methyltransferase.
The Day God Blinked
(2008)
The Day God Blinked x-rays the politico-economic and socio-moral life of a rich and resourceful country called Ewawa from 1982 to 2007. The country had been ruled by a dynamic and insightful miser known as the Old Man. But because he had been in power for too long, his citizens longed for change. It happened when nobody expected it. The old man died suddenly in his sleep and was replaced by his handpicked successor. Unfortunately, the successor whom everybody had expected would do better plunged the country into terrible economic and moral crises. Lucia, the protagonist, narrates her predicament. To her, Ewawa is rotten in all totality. There is nowhere to turn for salvation. The custodians of the economic, social, moral and spiritual values of the land are not up to the task. The country is without hope. Is all doomed?
Previous evidence suggests that less liquid stocks entail higher average returns. Using NYSE data, we present evidence that both the sensitivity of returns to liquidity and liquidity premia have significantly declined over the past four decades to levels that we cannot statistically distinguish from zero. Furthermore, the profitability of trading strategies based on buying illiquid stocks and selling illiquid stocks has declined over the past four decades, rendering such strategies virtually unprofitable. Our results are robust to several conventional liquidity measures related to volume. When using liquidity measure that is not related to volume, we find just weak evidence of a liquidity premium even in the early periods of our sample. The gradual introduction and proliferation of index funds and exchange traded funds is a possible explanation for these results.
Vertov defined the basic qualities of his Cine-Eye by means of a simple negation: it sees what remains inaccessible to the human eye. This means that in his films we see media-based and media-produced images that have nothing to do with the imitation of human perception. According to Vertov, such filmic, telescopic, or microscopic perception develops, educates, and expands the viewer’s analytical abilities. Thus, we have on the one hand a media-induced perception and on the other a new assemblage or montage of the fragments of this mediated perception. This new montage is based on a specific interaction and follows poetic rather than prosaic rules. It is freed from such constraints as time, space, causality, or speed. In other words it is based on properly media-specific qualities and, following the terminology of the Russian Futurists who influenced Vertov in his youth, it constitutes zaum or transrationality.
The case for privatization, whether defined in a broad or narrow sense, has been forcefully made by its advocates against the backdrop of the much advertised poor performances of state-owned enterprises (SOEs) and theoretical arguments relating to the efficiency of private firms over public enterprises. Consequently, privatization and commercialization have been key components of the structural adjustment programmes foisted by the Bretton Woods institutions on Third World countries. Yet, the empirical findings on privatization, especially outside Africa where they exist, do not portray the strategy to be a panacea that works in all circumstances in all branches of economic activity. In spite of this, since the late 1980s, privatization has been stepped up in almost all African countries. And after about two decades of vigorous implementation of privatization programmes in Africa, there is a compelling need for a comprehensive and systematic analysis of various privatization issues, particularly the economic and social impact. This book thus establishes a clear case for a comprehensive and systematic analysis of the impact of privatization in Africa. Specifically, the book provides a state-of-the art review of privatization issues and research questions as a prelude to an in-depth study of the economic and social impact of privatization. In the light of the rich insights brought to bear on the issues, this book should stimulate the interest of researchers, donors and policy makers to undertake or support the follow-up in-depth research envisaged.
Based on a unique dataset of legislative changes in industrial countries, we identify events that strengthen the competition control of mergers and acquisitions, analyze their impact on banks and non-financial firms and explain the different reactions observed with specific regulatory characteristics of the banking sector. Covering nineteen countries for the period 1987 to 2004, we find that more competition-oriented merger control increases the stock prices of banks and decreases the stock prices of non-financial firms. Bank targets become more profitable and larger, while those of non-financial firms remain mostly unaffected. A major determinant of the positive bank returns is the degree of opaqueness that characterizes the institutional setup for supervisory bank merger reviews. The legal design of the supervisory control of bank mergers may therefore have important implications for real activity.
