Discourses of equality in post-Agreement Northern Ireland

This article analyses the use of equality as a concept central to the implementation of the 1998 Good Friday Agreement in Northern Ireland. The authors argue that, although equality legislation is succeeding in redressing previous discrimination in society, the discourses that have emerged around it have exacerbated competition and polarization between communities for two main reasons. Firstly, in " selling' the Agreement to their supporters, political elites have appropriated community-specific definitions of the concept, thus reinforcing rather than weakening group differences. Secondly, the practice of equality legislation involves the definitive categorization of individuals as members of particular groups. This article examines these processes and their effects through the analysis of the discourse of nationalist and Unionist Party elites and of individual Catholics and Protestants. This is done in order to capture the dynamics of change in political communication and identification rather than simply describing institutional alterations.

Amorous Ex/Incursions: Love in Writings of Badiou, Weil, Fromm, and Barthes

My dissertation explores the enabling contributions of love to the practice of ethico-political and cultural critique. Engaging with the work of Alain Badiou, Simone Weil, Erich Fromm, and Roland Barthes, I examine love in terms of the following modalities: waiting, giving, and looking. I place the aforementioned thinkers in dialogue with selected literary and cinematic texts to explicate and interrogate the meaningful possibilities of their discourse on love. In my chapter on Alain Badiou, I discuss his ontology, which I draw upon heavily to set the theoretical parameters of my study. I also discuss the logic of love that he develops in his philosophy. Speaking to the problem of pre-Evental agency that critics of his work identify, I suggest that waiting as attention, as theorized by Simone Weil, might be the closest form of agency that a pre-Evental (amorous) being can experience. In my discussion of Erich Fromm, I reevaluate his “art of loving” within the constellation of late capitalism. Reading his work through a Lacanian lens, I explore the utility of his prescriptions by examining Chuck Palahniuk’s controversial novel Fight Club. In my chapter on Roland Barthes, I theorize the possibility of cinematic looking that does not depend on the antagonism inherent in the binaries masculine/ feminine and (Gazing) spectator/ (to-be-looked-at) image. Towards this objective, I propose the “amorous look,” a mode of viewing occasioned by cinematic punctual encounters, that I contend is beyond the domain of desire and perversion. I deploy the “amorous look” as I reflect on Aureus Solito’s film Ang Pagdadalaga ni Maximo Olivares (The Blossoming of Maximo Olivares) and its representations of love and waiting.

Metastasis-inducing DNA Regulates the Expression of the Osteopontin Gene by Binding the Transcription Factor Tcf-4

Small 1,000-bp fragments of genomic DNA obtained from human malignant breast cancer cell lines when transfected into a benign rat mammary cell line enhance transcription of the osteopontin gene and thereby cause the cells to metastasize in syngeneic rats. To identify the molecular events underlying this process, transient cotransfections of an osteopontin promoter-reporter construct and fragments of one metastasis-inducing DNA (Met-DNA) have identified the active components in the Met-DNA as the binding sites for the T-cell factor (Tcf) family of transcription factors. Incubation of cell extracts with active DNA fragments containing the sequence CAAAG caused retardation of their mobilities on polyacrylamide gels, and Western blotting identified Tcf-4, beta-catenin, and E-cadherin in the relevant DNA complexes in vitro. Transfection of an expression vector for Tcf-4 inhibited the stimulated activity of the osteopontin promoter-reporter construct caused by transiently transfected active fragments of Met-DNA or permanently transfected Met-DNA. This stimulated activity of the osteopontin promoter-reporter construct is accompanied by an increase in endogenous osteopontin mRNA but not in fos or actin mRNAs in the transfected cells. Permanent transfection of the benign rat mammary cell line with a 20-bp fragment from the Met-DNA containing the Tcf recognition sequence CAAAG caused an enhanced permanent production of endogenous osteopontin protein in vitro and induced the cells to metastasize in syngeneic rats in vivo. The corresponding fragment without the CAAAG sequence was without either effect. Therefore, the regulatory effect of the C9-Met-DNA is exerted, at least in part, by a CAAAG sequence that can sequester the endogenous inhibitory Tcf-4 and thereby promote transcription of osteopontin, the direct effector of metastasis in this system.

Proteomic Analysis of Recurrent Joint Inflammation in Juvenile Idiopathic Arthritis

The synovial fluid proteome in juvenile idiopathic arthritis was investigated to isolate joint-specific biomarkers that are expressed in patients displaying recurrent joint inflammation. To identify the synovial specific proteome, matched synovial fluid and plasma samples were subjected to protein separation by 2-dimension electrophoresis (2DE). Forty-three protein spots, overexpressed in the joint, were identified. Synovial fluids from children with single-event knee joint inflammation were then compared with a group with recurrent knee disease. Nine synovial specific proteins were significantly differentially expressed in the recurrent group. Proteolytic fragments of collagen X, fibrin beta-chain, and T-cell receptor alpha-region have been identified among this protein cluster. Putative biomarkers, overexpressed in the joint and differentially expressed in children with recurrent joint inflammation, have been identified. These proteins may play a significant role determining the pathological state within the chronically inflamed joint and influence disease progression in JIA. This is the first study of the synovial proteome in children.

Reading of audiovisual productions of contemporary art in art education

This article focuses on the reading of audiovisual productions of contemporary art as a creative process, seeking to analyse which effects of meaning the articulations between the visual and sound systems produce, and the meaning that children give to then. It describes a video art, identifying the languages that compose it and the relationships that link them. Such reading exercise had as corpus of analysis the Chair video art, by Masaru Ozaki, and counted with the theoretical and methodological support of the discourse semiotics, especially with studies on assembly procedures that articulate visual and auditory languages. Also, it presents a focal study with the meanings that a group of children gave to the video art. The findings indicate the importance of including the reading of audiovisual productions of contemporary art at school through the problematization of effects of meaning produced by the interrelation between different languages. And they suggest some subsidies that allow teachers from different areas of knowledge to reflect about the visuality in their pedagogical practice; the choice of the audiovisual materials taken to the classroom and other ways of seeing these texts edited.

Detection and localisation of protein-protein interactions in Saccharomyces cerevisiae using a split-GFP method

An alternative method for monitoring protein-protein interactions in Saccharomyces cerevisiae has been developed. It relies on the ability of two fragments of enhanced green fluorescent protein (EGFP) to reassemble and fluoresce when fused to interacting proteins. Since this fluorescence can be detected in living cells, simultaneous detection and localisation of interacting pairs is possible. DNA sequences encoding N- and C-terminal EGFP fragments flanked by sequences from the genes of interest were transformed into S. cerevisicie JPY5 cells and homologous recombination into the genome verified by PCR. The system was evaluated by testing known interacting proteins: labelling of the phosphofructokinase subunits, Pfk1p and Pfk2p, with N- and C-terminal EGFP fragments, respectively, resulted in green fluorescence in the cytoplasm. The system works in other cellular compartments: labelling of Idh1p and Idh2p, (mitochondrial matrix), Sdh3p and Sdh4p (mitochondrial membrane) and Pap2p and Mtr4p (nucleus) all resulted in fluorescence in the appropriate cellular compartment.

High levels of genetic structuring as a result of population fragmentation in the tropical tree species Caesalpinia echinata Lam.

We have investigated levels of genetic diversity within and among seven remnant populations of Caesalpinia echinata Lam., an endangered species found as fragmented populations in three major areas around the coastal regions of Brazil. Using amplified fragment length polymorphism (AFLP) genetic markers, we detected levels of within-population genetic diversity ranging from 0.092 to 0.163, with the lowest values generally being found in the smallest populations. Estimates of between-population genetic differentiation were strongly correlated with geographical distance ( r = 0.884, p <0.001), which, along with a neighbour-joining phylogenetic analysis, strongly suggested high levels of genetic isolation by distance. Over half (62%) of the total genetic diversity was partitioned between populations, further highlighting the genetic distinctness of individual populations. Taken together, these results suggest that fragmentation has led to an increase in population differentiation between fragments of C. echinata. These formations will be of great value in the development of conservation plans for species exhibiting high levels of genetic differentiation due to fragmentation, such as indication of conservation unit size, which populations should be chosen as priority in conservation plans and which samples should be introduced in areas with a low number of individuals of brazilwood.

The impact and recovery of asteroid 2008 TC3

In the absence of a firm link between individual meteorites and their asteroidal parent bodies, asteroids are typically characterized only by their light reflection properties, and grouped accordingly into classes. On 6 October 2008, a small asteroid was discovered with a flat reflectance spectrum in the 554-995nm wavelength range, and designated 2008 TC3 (refs 4-6). It subsequently hit the Earth. Because it exploded at 37km altitude, no macroscopic fragments were expected to survive. Here we report that a dedicated search along the approach trajectory recovered 47 meteorites, fragments of a single body named Almahata Sitta, with a total mass of 3.95kg. Analysis of one of these meteorites shows it to be an achondrite, a polymict ureilite, anomalous in its class: ultra-fine-grained and porous, with large carbonaceous grains. The combined asteroid and meteorite reflectance spectra identify the asteroid as F class, now firmly linked to dark carbon-rich anomalous ureilites, a material so fragile it was not previously represented in meteorite collections.

The Open Method of Coordination on Health Care After the Lisbon Strategy II: Towards a Neoliberal Framing?

This paper undertakes a content analysis of the discourse on the Open Method of Coordination on Health Care (OMC/HC) in order to show how equity and solidarity are increasingly linked to optimisation and, as such, how neoliberalism increasingly frames health care. Some of the side-effects of this reframing for politics are highlighted: legitimating and extending EU governance, reducing the space for oppositional formations and limited citizenship. The analysis begins by interrogating the broader context of the Lisbon Strategy II, after which the techniques of the OMC/HC and its substantive outputs are analysed.

Proteomic analysis of circulating immune complexes in juvenile idiopathic arthritis reveals disease-associated proteins

Juvenile idiopathic arthritis reflects a group of clinically heterogeneous arthritides hallmarked by elevated concentrations of circulating immune complexes. In this study, the circulating immune complex proteome was examined to elucidate disease-associated proteins that are overexpressed in patients with an aggressive, and at times destructive, disease phenotype. To solve this proteome, circulating immune complexes were isolated from the sera of patients with chronic, erosive or early-onset, aggressive disease and from patients in medical remission or healthy controls subsequent to protein separation by 2-DE. Thirty-seven protein spots were overexpressed in the circulating immune complexes of the aggressive disease groups as compared to controls, 28 of which have been confidently identified to date. Proteolytic fragments of glyceraldehyde-3-phosphate dehydrogenase, serotransferrin, and a-1-antitrypsin have been identified among others. In total, these 28 putative disease-associated proteins most definitely contribute to immune complex formation and likely have a significant role in disease etiology and pathogenesis. Moreover, these proteins represent markers of aggressive disease, which could aid in diagnosis and management strategies, and potential therapeutic targets to prevent or control disease outcome. This is the first in-depth analysis of the circulating immune complex proteome in juvenile idiopathic arthritis.

The discursive capacity of graphic design

The relationship between rhetoric and graphic design is presented in this article. The comparison between a classical orator and a graphic designer, between a discourse and a piece of design comes from the connections between with the communication and creativity. We will see how an application of the fundamentals of rhetoric can open new doors to the professional practice, the education of graphic design and the same theory of the rhetoric of the image.By the analysis of a design is exemplified the points of union that show how the arguments, operations, figures of discourse and rhetorical phases are present in the creative process of graphic design and how designers, perhaps unconsciously, use techniques that were traditional. In other words, graphic design is a rhetorical construction.There is then a transposition of a discourse model created by linguistic signs to a discourse model consists of visual and typographic signs, causing design is seen as a discursivediscipline that goes beyond the aesthetic component.

The Rhetorical Construction of Corporate Logos

This research is set in the context of today’s societies, in which the corporate visual symbology of a business, corporation or institution constitutes an essential way to transmit its corporate image. Traditional discursive procedures can be discovered in the development of these signs. The rhetorical strategies developed by the great classical authors appear in the logo-symbols expressing the corporate values of today’s companies. Thus, rhetoric is emerging once again in the sense it had many centuries ago: A repertory of rules that, paradoxically, standardizes the deviations of language and whose control is synonymous with power. The main objective of this study is to substantiate the rhetorical construction of logos using as a model of analysis the classical process of creating discourse. This involves understanding logos as persuasive discourses addressed to a modern audience. Our findings show that the rhetorical paradigm can be considered as a creative model for the con­struction of an original logo consistent with a company’s image.

The rhetoric of acculturation: When integration means assimilation

Viewing traditional acculturation literature through a social constructionist lens, the present paper identifies a number of limitations with this research. A discourse analytic approach to acculturation is offered as a means of addressing some of these issues. Drawing on examples taken from British print media debate surrounding the issue of faith schooling in the UK, an analysis is presented which illustrates the manner in which, though optimally positioned within acculturative moral hierarchies directed towards the legitimization of both pro- and anti-faith schooling debates, integration rhetoric often conceals the (re-)production of a more implicit assimilationism. Findings are discussed in terms of their implications for hegemonically structured acculturative power relations. This exploratory analysis provides the basis for reflection on the benefits of a discursive approach to acculturation. Moreover, the dependence of integrationist discourse on a series of socio-spatial resources is considered and, following on from Dixon and Durrheim's (2000) discursive re-conceptualization of place-identity, is taken to signify the need for a more environmentally 'grounded' approach to acculturation.

Multiple origins of European populations of giant liver fluke Fascioloides magna (Trematoda: Fasciolidae), an invasive liver parasite of ruminants

The giant liver fluke, Fascioloides magna, liver parasite of free-living and domestic ruminants of Europe and North America, was analysed in order to determine the origin of European populations and to reveal the biogeography of this originally North American parasite on the European continent. The previously selected variable fragments of the mitochondrial cytochrome c oxidase subunit I (cox1; 384 bp) and nicotinamid dehydrogenase subunit I (nad1; 405 bp) were applied as a tool. The phylogenetic trees and haplotype networks were constructed and the level of genetic structuring was evaluated using population genetic tools. In F. magna individuals originating from all European natural foci (Italy, Czech Republic, Danube floodplain forests) and from four of five major North American enzootic areas, 16 cox1 and 18 nad1 haplotypes were determined. The concatenated sequence set produced 22 distinct haplotypes. The European fluke populations were less diverse than those from North America in that they contained proportionately fewer haplotypes (8), while more substantial level of genetic diversity and higher number of haplotypes (15) were recorded in North America. Only one haplotype was shared between the European (Italy) and North American (USA/Oregon and Canada/Alberta) flukes supporting a western North American origin of the Italian F. magna population. Haplotypes found in Italy were distinct from those determined in the remaining European localities what indicates that introduction of F. magna onto the European continent is a result of more than one event. In Czech focus, a south-eastern US origin of giant liver fluke was revealed. Identical haplotypes, common for parasites from Czech Republic and from expanding focus of Danube floodplain forests, implies introduction of F. magna to the Danube region from an already established Czech focus.

A Monte Carlo model of DNA double-strand break clustering and rejoining kinetics for the analysis of pulsed-field gel electrophoresis data

In studies of radiation-induced DNA fragmentation and repair, analytical models may provide rapid and easy-to-use methods to test simple hypotheses regarding the breakage and rejoining mechanisms involved. The random breakage model, according to which lesions are distributed uniformly and independently of each other along the DNA, has been the model most used to describe spatial distribution of radiation-induced DNA damage. Recently several mechanistic approaches have been proposed that model clustered damage to DNA. In general, such approaches focus on the study of initial radiation-induced DNA damage and repair, without considering the effects of additional (unwanted and unavoidable) fragmentation that may take place during the experimental procedures. While most approaches, including measurement of total DNA mass below a specified value, allow for the occurrence of background experimental damage by means of simple subtractive procedures, a more detailed analysis of DNA fragmentation necessitates a more accurate treatment. We have developed a new, relatively simple model of DNA breakage and the resulting rejoining kinetics of broken fragments. Initial radiation-induced DNA damage is simulated using a clustered breakage approach, with three free parameters: the number of independently located clusters, each containing several DNA double-strand breaks (DSBs), the average number of DSBs within a cluster (multiplicity of the cluster), and the maximum allowed radius within which DSBs belonging to the same cluster are distributed. Random breakage is simulated as a special case of the DSB clustering procedure. When the model is applied to the analysis of DNA fragmentation as measured with pulsed-field gel electrophoresis (PFGE), the hypothesis that DSBs in proximity rejoin at a different rate from that of sparse isolated breaks can be tested, since the kinetics of rejoining of fragments of varying size may be followed by means of computer simulations. The problem of how to account for background damage from experimental handling is also carefully considered. We have shown that the conventional procedure of subtracting the background damage from the experimental data may lead to erroneous conclusions during the analysis of both initial fragmentation and DSB rejoining. Despite its relative simplicity, the method presented allows both the quantitative and qualitative description of radiation-induced DNA fragmentation and subsequent rejoining of double-stranded DNA fragments.
