Performing the paradox: collaboration as intervention in Eis o Homem

After the economic crisis of 2008, Portugal, like other European countries, underwent a readjustment programme based on neo-liberal principles. This programme widened the gap between rich and poor and elevated the economic over the social, the political and the affective. This paper analyses the devised performance Eis o Homem (Behold Man) as both an artistic and intellectual intervention in this context of crisis. It suggests that collaboration between artists on an explicitly non-hierarchical basis functioned as a coping mechanism for both the artists involved and the audience. The material generated during rehearsals contrasted the powerful reality of life as lived by Portuguese citizens during this period with the Real, that, as Slavoj Zizek has argued, masked this reality with social discourses that emphasized that there was no alternative to the dominance of the market. It concludes that such forms of theatrical collaboration, which explicitly contemplate the right to dissensus, can lead to complex, transformative responses to social situations and to dialogically-informed performances

Lepton flavor conserving Z -> l^+ l^-$ decays in the general two Higgs doublet model

We calculate the new physics effects to the branching ratios of the lepton flavor conserving decays Z -> l^+ l^- in the framework of the general two Higgs Doublet model. We predict the upper limits for the couplings |\bar{\xi}^{D}_{N,\mu\tau}| and |\bar{\xi}^{D}_{N,\tau\tau}| as 3\times 10^2 GeV and 1\times 10^2 GeV, respectively.Comment: 9 pages, 3 figure

Characteristics of summer-time energy exchange in a high Arctic tundra heath 2000–2010

Global warming will bring about changes in surface energy balance of Arctic ecosystems, which will have implications for ecosystem structure and functioning, as well as for climate system feedback mechanisms. In this study, we present a unique, long-term (2000–2010) record of summer-time energy balance components (net radiation, R n; sensible heat flux, H; latent heat flux, LE; and soil heat flux, G) from a high Arctic tundra heath in Zackenberg, Northeast Greenland. This area has been subjected to strong summer-time warming with increasing active layer depths (ALD) during the last decades. We observe high energy partitioning into H, low partitioning into LE and high Bowen ratio (β=H/LE) compared with other Arctic sites, associated with local climatic conditions dominated by onshore winds, slender vegetation with low transpiration activity and relatively dry soils. Surface saturation vapour pressure deficit (D s) was found to be an important variable controlling within-year surface energy partitioning. Throughout the study period, we observe increasing H/R n and LE/R n and decreasing G/R n and β, related to increasing ALD and decreasing soil wetness. Thus, changes in summer-time surface energy balance partitioning in Arctic ecosystems may be of importance for the climate system

The grit in the oyster: using energy biographies to question socio-technical imaginaries of ‘smartness’

It has been argued that responsible research and innovation (RRI) requires critique of the ‘worlds’ implicated in the future imaginaries associated with new technologies. Qualitative social science research can aid deliberation on imaginaries by exploring the meanings of technologies within everyday practices, as demonstrated by Yolande Strengers’ work on imaginaries of ‘smartness’. In this paper, we show how a novel combination of narrative interviews and multimodal methods can help explore future imaginaries of smartness through the lens of biographical experiences of socio-technical changes in domestic energy use. In particular, this approach can open up a critical space around socio-technical imaginaries by exploring the investments that individuals have in different forms of engagement with the world. The paper works with a psychosocial conceptual framework that draws on theoretical resources from science and technology studies to explain how valued forms of subjectivity may be conceptualised as emerging out of the ‘friction’ of engagement with the world. Using this framework, we show how biographical narratives of engagement with technologies from the Energy Biographies project can extend into critical deliberation on future imaginaries. The paper demonstrates the value of ‘thick’ data relating to the affective dimensions of subjective experience for RRI

Architects of time: Labouring on digital futures

Drawing on critical analyses of the internet inspired by Gilles Deleuze and the Marxist autonomia movement, this paper suggests a way of understanding the impact of the internet and digital culture on identity and social forms through a consideration of the relationship between controls exercised through the internet, new subjectivities constituted through its use and new labour practices enabled by it. Following Castells, we can see that the distinction between user, consumer and producer is becoming blurred and free labour is being provided by users to corporations. The relationship between digital technologies and sense of community, through their relationship to the future, is considered for its dangers and potentials. It is proposed that the internet may be a useful tool for highlighting and enabling social connections if certain dangers can be traversed. Notably, current remedies for the lack of trust on the internet are questioned with an alternative, drawing on Zygmunt Bauman and Georg Simmel, proposed which is built on community through a vision of a ‘shared network’

Training the homo cellularis: attention and the mobile phone

Drawing on literature from philosophy of technology, mobile media studies, performer training as well as practice-based research, this article examines the use of mobile phones in performer training, through the notion of pharmakon and in relation to questions of attention. It reviews the work of other performer training practitioners who use mobile phones and examines underlying assumptions with regard to the nature of attention and the use of space. Although the aim of this article is neither to advocate nor apologise for mobile phone use, it argues that the mobile phone may invite a rethinking of the way attention is exercised and understood within performer training. By discussing an exercise developed by the author within a university-based theatre training context, this article argues that an ‘attention–distraction’ dichotomy in terms of the trainee’s attending capacity is no longer an adequate explanatory framework. It therefore suggests that attention should be approached as a multi-modal and synthesising process

Education, digitization and literacy training. A historical and cross-cultural perspective.

In this article, I deal with the transition from traditional ‘school’ forms of instruction to educational processes that are fully mediated by digital technologies. Against the background of the idea the very institution ‘school’ is closely linked to the invention of the alphabetic writing system and to the need of initiating new generations into a literate culture, I focus on the issue of literacy training. I argue that with the digitization of education, a fundamental transition takes place regarding what it means to be literate, but also what it means to educate and to be educated. I do so by developing a ‘techno-somatic’ approach, which means that I look at the use of concrete instructional technologies, and the bodily disciplines that are involved. I set out a double comparison in which I contrast existing, ‘traditional’ ways of learning how to read/write with the way in which literacy training looked like before the nineteenth century, on the one hand, and with the initiation into literacy in the Chinese/Japanese language, on the other hand. I argue that these comparisons shed light on the differences between traditional and digital literacy. More precisely, I show that in each case, a different relation toward what it means to produce script is involved. As such, both forms of literacy go together with different spaces of experience and senses of being-able, and therefore with altogether different ideas of what education is all about

Weak magnetic dipole moments in two-Higgs-doublet models

We investigate the effects of the new scalars in a two-Higgs-doublet model on the weak magnetic dipole moments of the fermions at the $Z$ peak. Proportionality of the Yukawa couplings to the fermion masses, and to $\tan{\beta}$, makes such effects more important for the third family, and potentially relevant. For the $\tau$ lepton, the new diagrams are suppressed by $v_\tau = 2 \sin^2 \theta_W - 1/2$, or by powers of $m_\tau/M_Z$, but may still be comparable to the SM electroweak contributions. In contrast, we find that the new contributions for the bottom quark may be much larger than the SM electroweak contributions. These new effects may even compete with the gluonic contribution, if the extra scalars are light and $\tan \beta$ is large. We also comment on the problem of the gauge dependence of the vertex, arising when the $Z$ is off mass shell. We compute the contributions from the new scalars to the magnetic dipole moments for top-quark production at the NLC, and for bottom and $\tau$ production at LEP2. In the case of the top, we find that the SM electroweak and gluonic contributions to the $Z t {\bar t}$ vertex are comparable. The new contributions may be of the same order of magnitude as the standard-model ones, but not much larger.Comment: 17 pages, LaTex, 8 figures available upon reques
