Impossible Participation

The chapter critiques the rise of participation in art since the 1990s – a development that sees artists and curators searching continually for new and increased levels of audience inclusion. While there has been much discussion about what might be gained by participating in an artwork, we ask what might be lost by this act. We also question the extent to which participation is a useful social or aesthetic strategy in circumstances where it remains bound by the institutional structures of the artworld. For this reason, our work is an attempt to transform the broader ‘apparatus of art’ and to create works in which the roles assigned to individuals and groups remain fluid and subject to continuous negotiation. As a means of an attempt at resisting absorption into the institutional structures of the artworld, we privilege a form of participation that remains immanent in the work, but that never crystallizes into a single or definable role. Kathryn Brown , art historian and editor of Interactive Contemporary Art, says, ‘It is, perhaps, a fitting end to the discussions of the present volume that the most interesting and valuable form of participation envisaged by Freee is one that must remain impossible.’

To Hell with Herbert Read

Freee write manifestos by taking a pencil (or a laptop) to an historical text, usually belonging to the entwined traditions of the avant-garde and political activism. Sometimes, as Tristan Tzara advised, we choose the text according to its length, while other times, such as in this instance, we selected the text according to the conditions of the invitation that triggered the writing of the manifesto. Our manifesto ‘To Hell with Herbert Read’ was written originally as a contribution to a conference held in Manchester that took its title from Herbert Read’s book ‘To Hell with Culture’. ‘To Hell with Culture’ is a book that cuts itself off from the world whereas ‘To Hell with Herbert Read’ relocates Read’s book in a world of cultural, social, economic and political actualities that are part of common experience. Read rejects culture because he thinks it is a useless, wasteful, elitist, puffed-up, decorative supplement to the functional, factual, palpable, purposeful world of things. He is a positivist kind of modernist who presents himself as the opposite, an enemy of the status quo. He is an anarchist of a particularly bourgeois hue: he wants us all to have decent pots and pans, not the inferior ones that are supplied by market forces cheaply. Rather than taking his aim precisely to target the dominant forces of his day - the industrial capitalists and their financiers - he rejects the world and all its inhabitants. He not only despises elitist culture but popular culture too.

A influência do perfeccionismo parental, dos estilos parentais e dos padrões de vinculação no desenvolvimento do perfeccionismo em jovens adultos

As conceções clássicas sobre as origens do perfeccionismo e os principais modelos explicativos do seu desenvolvimento assentam no pressuposto de que a relação parental constitui um importante fator na compreensão deste traço de personalidade nos filhos. Apesar do suporte teórico e conceptual, os resultados da investigação empírica são parciais e pouco conclusivos. Neste contexto, definimos como objetivos principais analisar a influência do Perfeccionismo parental no desenvolvimento do Perfeccionismo dos filhos jovens adultos e compreender o papel dos Estilos Parentais e dos Padrões de Vinculação. Procurou-se ainda averiguar se o efeito destas variáveis era moderado pelo sexo do progenitor ou pelo sexo do filho. Os resultados encontrados permitem um conhecimento mais aprofundado sobre o papel destes fatores parentais. A perceção de um Estilo Parental Autoritário e de uma Vinculação pouco Segura aos pais parece contribuir marcadamente para o desenvolvimento do Perfeccionismo Desadaptativo. Por outro lado, um Estilo Parental Democrático e uma Vinculação Segura parecem apenas influenciar uma parte do Perfeccionismo o Adaptativo. O estudo do contributo diferencial de cada um dos progenitores no desenvolvimento do perfeccionismo em função do sexo do filho permitiu testar as duas hipóteses descritas na literatura sobre o papel moderador do sexo. Os dados sugerem que os filhos desenvolvem tendências perfeccionistas pela identificação com o progenitor do mesmo sexo (hipótese do cuidador do mesmo sexo), enquanto a componente desadaptativa do perfeccionismo parece desenvolve-se tanto nos filhos do sexo masculino como nas filhas quando a mãe manifesta também níveis elevados de Perfeccionismo Desadaptativo (hipótese do cuidador principal). Os resultados apoiam ainda o Modelo da Aprendizagem Social e o Modelo das Expectativas Sociais formulados por Flett, Hewitt, Oliver e Macdonald (2002). Por último, são discutidas as implicações destes resultados na prevenção e na intervenção psicológica com pais e filhos e apontadas algumas das limitações do presente trabalho que poderão ser colmatadas em futuras investigações.

Transmissão intergeracional do perfecionismo: o papel do perfecionismo parental e da perceção das expectativas, críticas e estilos parentais, no desenvolvimento de perfecionismo dos filhos

Os objetivos do presente estudo recaem sobre a investigação do papel do perfecionismo parental, bem como da perceção dos filhos sobre as expetativas, críticas e autoritarismo parental na transmissão intergeracional do perfecionismo. Participaram no estudo 156 estudantes universitários de ambos os sexos, com idades compreendidas entre os 18 e os 30 anos de idade, e os seus respetivos pais (pai e mãe). Os instrumentos aplicados aos filhos consistiram num Questionário Sociodemográfico, na Multidimensional Perfectionism Scale de Hewitt e Flett (1991b), na Multidimensional Perfectionism Scale de Frost, Marten, Lahart e Rosenblate (1990) e no Parental Authoritative Questionaire de Buri (1991). Os pais responderam à Multidimensional Perfectionism Scale de Hewitt e Flett (1991b). Os resultados indicaram uma correspondência entre as mesmas dimensões de perfecionismo de pais e filhos, apoiando a premissa de que a transmissão do perfecionismo se realiza por aprendizagem social, através da imitação das tendências perfecionistas dos pais. No entanto, verificou-se ainda correspondência entre dimensões diferentes de perfecionismo de pais e filhos, indicando a possibilidade de existirem outros mecanismos na transmissão intergeracional deste traço de personalidade. Especificamente, os resultados indicaram que as expetativas parentais apresentam um papel importante na transmissão de perfecionismo socialmente prescrito entre mãe e filho e parecem também contribuir para o desenvolvimento de PAO e PSP, mesmo sem que haja necessariamente perfecionismo parental. O estudo permitiu ainda analisar o papel do sexo na transmissão do perfecionismo, podendo constatar-se que tanto o cuidador principal como o cuidador do mesmo sexo contribuem para o desenvolvimento de perfecionismo dos filhos, dependendo das dimensões do perfecionismo que se avaliam, existindo situações em que se verifica o contributo simultâneo de ambos. O significado os resultados é discutido em termos das implicações dos fatores parentais para a transmissão intergeracional do perfecionismo.

Analysis of underwater acoustic data via 3-D segmentation

The analysis of seabed structure is important in a wide variety of scientific and industrial applications. In this paper, underwater acoustic data produced by bottom-penetrating sonar (Topas) are analyzed using unsupervised volumetric segmentation, based on a three dimensional Gibbs-Markov model. The result is a concise and accurate description of the seabed, in which key structures are emphasized. This description is also very well suited to further operations, such as the enhancement and automatic recognition of important structures. Experimental results demonstrating the effectiveness of this approach are shown, using Topas data gathered in the North Sea off Horten, Norway.

Preface

Information and Communication Technologies (ICT) play a major role in our lives. However, ICT development which is indifferent to the concerns of social inclusion may raise barriers and increase the gap between the average user and those with special needs, instead of contributing to eliminating this gap and promoting equal rights and opportunities for all. Senior citizens and others with special needs are often faced with multiple minor disabilities that prevent them from enjoying the benefits of technology and higher quality of life standards. According to the UN Convention on the Rights of Persons with Disabilities, technology design should take into account accessibility and usability features for the protection and promotion of the human rights of persons with disabilities, in all policies and programmes.

How new online communication tools and the availability of content influence the audiences and the creative process

We live in a changing world. At an impressive speed, every day new technological resources appear. We increasingly use the Internet to obtain and share information, and new online communication tools are emerging. Each of them encompasses new potential and creates new audiences. In recent years, we witnessed the emergence of Facebook, Twitter, YouTube and other media platforms. They have provided us with an even greater interactivity between sender and receiver, as well as generated a new sense of community. At the same time we also see the availability of content like it never happened before. We are increasingly sharing texts, videos, photos, etc. This poster intends to explore the potential of using these new online communication tools in the cultural sphere to create new audiences, to develop of a new kind of community, to provide information as well as different ways of building organizations’ memory. The transience of performing arts is accompanied by the need to counter that transience by means of documentation. This desire to ‘save’ events reaches its expression with the information archive of the different production moments as well as the opportunity to record the event and present it through, for instance, digital platforms. In this poster we intend to answer the following questions: which online communication tools are being used to engage audiences in the cultural sphere (specifically between theater companies in Lisbon)? Is there a new relationship with the public? Are online communication tools creating a new kind of community? What changes are these tools introducing in the creative process? In what way the availability of content and its archive contribute to the organization memory? Among several references, we will approach the two-way communication model that James E. Grunig & Todd T. Hunt (1984) already presented and the concept of mass self-communication of Manuel Castells (2010). Castells also tells us that we have moved from traditional media to a system of communication networks. For Scott Kirsner (2010), we have entered an era of digital creativity, where artists have the tools to do what they imagined and the public no longer wants to just consume cultural goods, but instead to have a voice and participate. The creativity process is now depending on the public choice as they wander through the screen. It is the receiver who owns an object which can be exchanged. Virtual reality has encouraged the receiver to abandon its position of passive observer and to become a participant agent, which implies a challenge to organizations: inventing new forms of interfaces. Therefore, we intend to find new and effective online tools that can be used by cultural organizations; the best way to manage them; to show how organizations can create a community with the public and how the availability of online content and its archive can contribute to the organizations’ memory.

L'Oreal acquisition policy: The Body Shop case study

The Work Project I present focuses on the analysis of L’Oréal acquisition policy, trying to outline if the M&A deals it has led over the last 14 years have succeeded in creating value. By replicating the model proposed by Todd Hazelkorn, Marc Zenner and Anil Shivdasani in their paper “Creating Value with Mergers and Acquisitions”, I analyzed the 29 M&A deals that L’Oréal has led worldwide, understanding the common factors able to explain the success of such transactions. Further, I focused on The Body Shop case study, a highly criticized and controversial acquisition that has proved to be profitable and able to create value.

Results of An International Study of Quantitative BCR/ABL Assays Using Defined RNA Samples

Molecular monitoring of BCR/ABL transcripts by real time quantitative reverse transcription PCR (qRT-PCR) is an essential technique for clinical management of patients with BCR/ABL-positive CML and ALL. Though quantitative BCR/ABL assays are performed in hundreds of laboratories worldwide, results among these laboratories cannot be reliably compared due to heterogeneity in test methods, data analysis, reporting, and lack of quantitative standards. Recent efforts towards standardization have been limited in scope. Aliquots of RNA were sent to clinical test centers worldwide in order to evaluate methods and reporting for e1a2, b2a2, and b3a2 transcript levels using their own qRT-PCR assays. Total RNA was isolated from tissue culture cells that expressed each of the different BCR/ABL transcripts. Serial log dilutions were prepared, ranging from 100 to 10-5, in RNA isolated from HL60 cells. Laboratories performed 5 independent qRT-PCR reactions for each sample type at each dilution. In addition, 15 qRT-PCR reactions of the 10-3 b3a2 RNA dilution were run to assess reproducibility within and between laboratories. Participants were asked to run the samples following their standard protocols and to report cycle threshold (Ct), quantitative values for BCR/ABL and housekeeping genes, and ratios of BCR/ABL to housekeeping genes for each sample RNA. Thirty-seven (n=37) participants have submitted qRT-PCR results for analysis (36, 37, and 34 labs generated data for b2a2, b3a2, and e1a2, respectively). The limit of detection for this study was defined as the lowest dilution that a Ct value could be detected for all 5 replicates. For b2a2, 15, 16, 4, and 1 lab(s) showed a limit of detection at the 10-5, 10-4, 10-3, and 10-2 dilutions, respectively. For b3a2, 20, 13, and 4 labs showed a limit of detection at the 10-5, 10-4, and 10-3 dilutions, respectively. For e1a2, 10, 21, 2, and 1 lab(s) showed a limit of detection at the 10-5, 10-4, 10-3, and 10-2 dilutions, respectively. Log %BCR/ABL ratio values provided a method for comparing results between the different laboratories for each BCR/ABL dilution series. Linear regression analysis revealed concordance among the majority of participant data over the 10-1 to 10-4 dilutions. The overall slope values showed comparable results among the majority of b2a2 (mean=0.939; median=0.9627; range (0.399 - 1.1872)), b3a2 (mean=0.925; median=0.922; range (0.625 - 1.140)), and e1a2 (mean=0.897; median=0.909; range (0.5174 - 1.138)) laboratory results (Fig. 1-3)). Thirty-four (n=34) out of the 37 laboratories reported Ct values for all 15 replicates and only those with a complete data set were included in the inter-lab calculations. Eleven laboratories either did not report their copy number data or used other reporting units such as nanograms or cell numbers; therefore, only 26 laboratories were included in the overall analysis of copy numbers. The median copy number was 348.4, with a range from 15.6 to 547,000 copies (approximately a 4.5 log difference); the median intra-lab %CV was 19.2% with a range from 4.2% to 82.6%. While our international performance evaluation using serially diluted RNA samples has reinforced the fact that heterogeneity exists among clinical laboratories, it has also demonstrated that performance within a laboratory is overall very consistent. Accordingly, the availability of defined BCR/ABL RNAs may facilitate the validation of all phases of quantitative BCR/ABL analysis and may be extremely useful as a tool for monitoring assay performance. Ongoing analyses of these materials, along with the development of additional control materials, may solidify consensus around their application in routine laboratory testing and possible integration in worldwide efforts to standardize quantitative BCR/ABL testing.

Proteomic and Metabolomic Analyses of Mitochondrial Complex I-deficient Mouse Model Generated by Spontaneous B2 Short Interspersed Nuclear Element (SINE) Insertion into NADH Dehydrogenase (Ubiquinone) Fe-S Protein 4 (Ndufs4) Gene.

Eukaryotic cells generate energy in the form of ATP, through a network of mitochondrial complexes and electron carriers known as the oxidative phosphorylation system. In mammals, mitochondrial complex I (CI) is the largest component of this system, comprising 45 different subunits encoded by mitochondrial and nuclear DNA. Humans diagnosed with mutations in the gene NDUFS4, encoding a nuclear DNA-encoded subunit of CI (NADH dehydrogenase ubiquinone Fe-S protein 4), typically suffer from Leigh syndrome, a neurodegenerative disease with onset in infancy or early childhood. Mitochondria from NDUFS4 patients usually lack detectable NDUFS4 protein and show a CI stability/assembly defect. Here, we describe a recessive mouse phenotype caused by the insertion of a transposable element into Ndufs4, identified by a novel combined linkage and expression analysis. Designated Ndufs4(fky), the mutation leads to aberrant transcript splicing and absence of NDUFS4 protein in all tissues tested of homozygous mice. Physical and behavioral symptoms displayed by Ndufs4(fky/fky) mice include temporary fur loss, growth retardation, unsteady gait, and abnormal body posture when suspended by the tail. Analysis of CI in Ndufs4(fky/fky) mice using blue native PAGE revealed the presence of a faster migrating crippled complex. This crippled CI was shown to lack subunits of the "N assembly module", which contains the NADH binding site, but contained two assembly factors not present in intact CI. Metabolomic analysis of the blood by tandem mass spectrometry showed increased hydroxyacylcarnitine species, implying that the CI defect leads to an imbalanced NADH/NAD(+) ratio that inhibits mitochondrial fatty acid β-oxidation.

Common variants near MC4R are associated with fat mass, weight and risk of obesity.

To identify common variants influencing body mass index (BMI), we analyzed genome-wide association data from 16,876 individuals of European descent. After previously reported variants in FTO, the strongest association signal (rs17782313, P = 2.9 x 10(-6)) mapped 188 kb downstream of MC4R (melanocortin-4 receptor), mutations of which are the leading cause of monogenic severe childhood-onset obesity. We confirmed the BMI association in 60,352 adults (per-allele effect = 0.05 Z-score units; P = 2.8 x 10(-15)) and 5,988 children aged 7-11 (0.13 Z-score units; P = 1.5 x 10(-8)). In case-control analyses (n = 10,583), the odds for severe childhood obesity reached 1.30 (P = 8.0 x 10(-11)). Furthermore, we observed overtransmission of the risk allele to obese offspring in 660 families (P (pedigree disequilibrium test average; PDT-avg) = 2.4 x 10(-4)). The SNP location and patterns of phenotypic associations are consistent with effects mediated through altered MC4R function. Our findings establish that common variants near MC4R influence fat mass, weight and obesity risk at the population level and reinforce the need for large-scale data integration to identify variants influencing continuous biomedical traits.
