La construcción de la oligarquía inmobiliario-financiera en la ciudad neoliberal. El caso de Palma (Mallorca)

El capitalismo financiero, mediante la financiarización del suelo y su conversión en capital ficticio ha reconfigurado el sistema de extracción de sus plusvalías, facilitando la disolución de la dicotomía propietario-promotor. El giro emprendedor de la ciudad neoliberal ha promovido un nuevo rol económico y político del espacio urbano, potenciando el papel del promotor en la toma de decisiones, e impulsando la construcción de una nueva élite: la oligarquía inmobiliario-financiera. Se pretende analizar la red empresarial que dicta la lógica espacial de Palma.

Measuring the stellar wind parameters in IGR J17544-2619 and Vela X-1 constrains the accretion physics in supergiant fast X-ray transient and classical supergiant X-ray binaries

Context. Classical supergiant X-ray binaries (SGXBs) and supergiant fast X-ray transients (SFXTs) are two types of high-mass X-ray binaries (HMXBs) that present similar donors but, at the same time, show very different behavior in the X-rays. The reason for this dichotomy of wind-fed HMXBs is still a matter of debate. Among the several explanations that have been proposed, some of them invoke specific stellar wind properties of the donor stars. Only dedicated empiric analysis of the donors’ stellar wind can provide the required information to accomplish an adequate test of these theories. However, such analyses are scarce. Aims. To close this gap, we perform a comparative analysis of the optical companion in two important systems: IGR J17544-2619 (SFXT) and Vela X-1 (SGXB). We analyze the spectra of each star in detail and derive their stellar and wind properties. As a next step, we compare the wind parameters, giving us an excellent chance of recognizing key differences between donor winds in SFXTs and SGXBs. Methods. We use archival infrared, optical and ultraviolet observations, and analyze them with the non-local thermodynamic equilibrium (NLTE) Potsdam Wolf-Rayet model atmosphere code. We derive the physical properties of the stars and their stellar winds, accounting for the influence of X-rays on the stellar winds. Results. We find that the stellar parameters derived from the analysis generally agree well with the spectral types of the two donors: O9I (IGR J17544-2619) and B0.5Iae (Vela X-1). The distance to the sources have been revised and also agree well with the estimations already available in the literature. In IGR J17544-2619 we are able to narrow the uncertainty to d = 3.0 ± 0.2 kpc. From the stellar radius of the donor and its X-ray behavior, the eccentricity of IGR J17544-2619 is constrained to e< 0.25. The derived chemical abundances point to certain mixing during the lifetime of the donors. An important difference between the stellar winds of the two stars is their terminal velocities (ν∞ = 1500 km s-1 in IGR J17544-2619 and ν∞ = 700 km s-1 in Vela X-1), which have important consequences on the X-ray luminosity of these sources. Conclusions. The donors of IGR J17544-2619 and Vela X-1 have similar spectral types as well as similar parameters that physically characterize them and their spectra. In addition, the orbital parameters of the systems are similar too, with a nearly circular orbit and short orbital period. However, they show moderate differences in their stellar wind velocity and the spin period of their neutron star which has a strong impact on the X-ray luminosity of the sources. This specific combination of wind speed and pulsar spin favors an accretion regime with a persistently high luminosity in Vela X-1, while it favors an inhibiting accretion mechanism in IGR J17544-2619. Our study demonstrates that the relative wind velocity is critical in class determination for the HMXBs hosting a supergiant donor, given that it may shift the accretion mechanism from direct accretion to propeller regimes when combined with other parameters.

Salir de casa para volver a casa : lectura de la genética autoficcional de Alejandro Zambra (2006-2011)

Ce travail est une analyse exhaustive des romans publiés par l’écrivain chilien Alejandro Zambra entre 2006 et 2011. Compte tenu de son appartenance à la génération postdictatoriale, on va se concentrer sur la reconstruction autofictionnelle de l’enfance, et sur la façon dont elle reproduit, questionne et renverse le récit dictatorial dominant qui relègue les enfants sur le plan des personnages secondaires. Pour identifier le développement du discours, on va s’appuyer sur des outils critiques de la génétique littéraire dont le concept central « d’avant-texte » nous permet de faire une lecture rétrospective de Bonsái et de La vida privada de los árboles comme des précurseurs idéologiques de Formas de volver a casa. En raison de la centralité jouée par l’espace dans ces romans, on va consacrer une grande partie du travail à la représentation spatiale et la manière dont l’espace configure la position des personnages à l’intérieur du schème narratif. C’est dans cette relation que l’on identifie la dichotomie spatiale élaborée dans les œuvres, car l’espace et la vie privée sont reliés à l’inertie et la résignation dans l’univers textuel, tandis que l’action et le questionnement appartiennent au domaine de l’espace et la vie publics. Lus l’un après l’autre, les romans témoignent du parcours suivi de l’écrivain, qui assimile le récit dictatorial en évitant la confrontation narrative au début, pour, par la suite, approcher le passé, l’histoire familiale et la dictature, dans un processus autofictionnel qui projette les différentes voies du retour chez soi.

Face Your Fears: Cleaning Gobies Inspect Predators despite Being Stressed by Them

social stressors typically elicit two distinct behavioural responses in vertebrates: an active response (i.e., "fight or flight") or behavioural inhibition (i.e., freezing). Here, we report an interesting exception to this dichotomy in a Caribbean cleaner fish, which interacts with a wide variety of reef fish clients, including predatory species. Cleaning gobies appraise predatory clients as potential threat and become stressed in their presence, as evidenced by their higher cortisol levels when exposed to predatory rather than to non-predatory clients. Nevertheless, cleaning gobies neither flee nor freeze in response to dangerous clients but instead approach predators faster (both in captivity and in the wild), and interact longer with these clients than with non-predatory clients (in the wild). We hypothesise that cleaners interrupt the potentially harmful physiological consequences elicited by predatory clients by becoming increasingly proactive and by reducing the time elapsed between client approach and the start of the interaction process. The activation of a stress response may therefore also be responsible for the longer cleaning service provided by these cleaners to predatory clients in the wild. Future experimental studies may reveal similar patterns in other social vertebrate species when, for instance, individuals approach an opponent for reconciliation after a conflict.

Involvement and detachment in David Cameron and Ed Miliband’s political discourse. An analysis of deictic shields on the pronoun ‘I’ in UK 2015 General Election news interviews

The goal of my study is to investigate the relationship between selected deictic shields on the pronoun ‘I’ and the involvement/detachment dichotomy in a sample of television news interviews. I focus on the use of personal pronouns in political discourse. Drawing upon Caffi’s (2007) classification of mitigating devices into bushes, hedges and shields, I focus on deictic shields on the pronoun ‘I’: I examine the way a selection of ‘I’-related deictic shields is employed in a collection of news interviews broadcast during the electoral campaign prior to the UK 2015 General Election. My purpose is to uncover the frequencies of each of the linguistic items selected and the pragmatic functions of those linguistic items in the involvement/detachment dichotomy. The research is structured as follows. Chapter 1 provides an account of previous studies on the three main areas of research: speech event analysis, institutional interaction and the news interview, and the UK 2015 General Election television programmes. Chapter 2 is centred on the involvement/detachment dichotomy: I provide an overview of nonlinguistic and linguistic features of involvement and detachment at all levels of sentence structure. Chapter 3 contains a detailed account of the data collection and data analysis process. Chapter 4 provides an accurate description of results in three steps: quantitative analysis, qualitative analysis and discussion of the pragmatic functions of the selected linguistic features of involvement and detachment. Chapter 5 includes a brief summary of the investigation, reviews the main findings, and indicates limitations of the study and possible inputs for further research. The results of the analysis confirm that, while some of the linguistic items examined point toward involvement, others have a detaching effect. I therefore conclude that deictic shields on the pronoun ‘I’ permit the realisation of the involvement/detachment dichotomy in the speech genre of the news interview.

Mineralogy ol late Quaternary marine sediments from the West and East Greenland shelves offshore from early Tertiary basalt outcrops

We use quantitative X-ray diffraction to determine the mineralogy of late Quaternary marine sediments from the West and East Greenland shelves offshore from early Tertiary basalt outcrops. Despite the similar basalt outcrop area (60 000-70 000 km**2), there are significant differences between East and West Greenland sediments in the fraction of minerals (e.g. pyroxene) sourced from the basalt outcrops. We demonstrate the differences in the mineralogy between East and West Greenland marine sediments on three scales: (1) modern day, (2) late Quaternary inputs and (3) detailed down-core variations in 10 cores from the two margins. On the East Greenland Shelf (EGS), late Quaternary samples have an average quartz weight per cent of 6.2 ± 2.3 versus 12.8 ± 3.9 from the West Greenland Shelf (WGS), and 12.02 ± 4.8 versus 1.9 ± 2.3 wt% for pyroxene. K-means clustering indicated only 9% of the samples did not fit a simple EGS vs. WGS dichotomy. Sediments from the EGS and WGS are also isotopically distinct, with the EGS having higher eNd (-18 to 4) than those from the WGS (eNd = -25 to -35). We attribute the striking dichotomy in sediment composition to fundamentally different long-term Quaternary styles of glaciation on the two basalt outcrops.

Amateurism and the Aesthetics of Lego Stop-Motion on YouTube

Do the “democratization” of media and the proliferation of online participatory culture undermine the aesthetic hegemony of professional filmmakers? This article is a case study of both more and less popular animated Lego videos, also called “brickfilms,” that asks how amateur videos adhere to and/or depart from professionalized aesthetic standards. It addresses the definitions of professionalism and amateurism and proposes that the dichotomy between democratization and ongoing elitism is insufficient to describe the complex dialogue between professional film aesthetics and amateur production—a dialogue that is diverse but nonetheless follows certain patterns. These patterns link Lego videos to silent era cinema as well as contemporary professional live-action and stop-motion animation. Furthermore, a mixture of parody, pastiche, and homage suggest that amateur work has a variety of affective relationships to professional work. Ultimately, amateur filmmaking indicates a negotiation of professional standards rather than slavish adherence.

Environmentalizing economic development: a South Asian perspective

South Asia's pursuit of economic development has entailed considerable damage to and exposed the fragility of the physical environment of the region. This paper provides an analytical overview of the of the environmental problem that manifest themselves in South Asia in a comparative perspective with East and Southeast Asian countries as well as selected developed market economics. To date, South Asian development process has been environment-intensive and environment-depleting. It is argued that environmental problems are likely to set serious constraints to sustain growth in production to support a growing population. By exploring the relationship between indices of human welfare and bio-diversity conservation. the paper exposes the dichotomy of the development process. Finally, the study underscores the need for a range of policy options that rely both based and non-market based instruments in an integrated setting to enviromnentalize South Asian economic development.

Love You to Death: Tale of Two Japanese Seals

The recent two cases related to seals in Japan illustrate the nature of the “values” created for animals in today’s societies: one that appeared in a river in Tokyo and gained a national pop star fame, the other supposedly extinct Japanese seal re-gaining an endangered status. This paper argues that the contrast of these cases exemplifies the images and values of nature are created, and the “wilderness” becomes over-romanticised and idealised as societies become further removed from the biosphere. This questions the meaning of the intrinsic value of nature—can it be totally free from our social needs and vested interest; is a truly bio-centric perspective possible? The paper suggests the irrelevance of the eco-centric- anthropocentric dichotomy to today’s social contexts where complex socio-cultural, economic, political issues are interwoven.

Positioning hierarchy in enterprise system change

There is a widening gulf in change literature between theoretical notions of evolving organisational form and the emerging reality that old and new organisational structures coexist. This paper explores this dichotomy in Enterprise Resource Planning change. It develops a cellular hierarchy framework to explain how different types of hierarchy coexist within the same organisation during the implementation of Enterprise Resource Planning. © 2006 The Author; Journal compilation © 2006 Blackwell Publishing Ltd.

A CONTRIBUIÇÃO DA FORMAÇÃO CONTINUADA PARA AS PROFESSORAS DE EDUCAÇÃO INFANTIL DO MUNICÍPIO DE SÃO PAULO

Esta pesquisa aborda a formação continuada das educadoras da Educação Infantil da rede pública municipal de São Paulo. A questão central a ser investigada refere-se à proposta de formação continuada oferecida pela Secretaria Municipal de Educação de São Paulo SMESP buscando pesquisar quais são as contribuições desse projeto para essas educadoras. O estudo foi desenvolvido a partir da percepção da importância da formação continuada como um caminho de ressignificação da identidade docente e um exercício reflexivo para as professoras desse segmento da educação considerando todo o seu processo de construção histórica. Tal segmento foi escolhido para esta pesquisa, pois estudos contemporâneos realizados por diversos autores tais como: Beatriz Cerisara, Patricia Prado, Zeila Demartini, Júlia Formosinho e João Oliveira-Formosinho, entre outros, consideram que essa é uma fase essencial, na qual está sempre presente a necessidade de se discutir a dicotomia entre o cuidar e o educar, e de se ressignificar a identidade das professoras enquanto profissionais de Educação Infantil. Nesse sentido, a pesquisa apresenta uma discussão teórica acerca da formação das professoras da Educação Infantil no Brasil finalizando com uma pesquisa de campo que avalia o Projeto Estratégico de Ação PEA -, como uma das propostas de formação continuada das professoras de Educação Infantil, por meio de entrevistas semiestruturadas realizadas com nove professoras da Educação Infantil dessa rede municipal. A pesquisa possibilitou observar a relevância do PEA para as professoras entrevistadas, no que diz respeito à formação continuada. O estudo constatou também que este projeto vem sendo alterado de forma positiva e significativa, a partir de ações direcionadas às necessidades específicas da Educação Infantil, com uma concepção sobre a criança como um sujeito de direito à voz e dotado de competências. Nesta pesquisa, como possibilidade de formação, observou-se ainda a contribuição do PEA, que em momentos coletivos, permite a troca entre os pares e a reflexão sobre suas práticas, tornando-as professoras mais autônomas em seu papel enquanto parte do processo de construção de aprendizagem pela criança.

Queer enough? Contested terrains of identity deployment in the context of gay and lesbian public activism in Poland

Gay and lesbian prides and marches are of crucial relevance to the way in which non-heterosexual lives are imagined internationally despite regional and national differences. Quite often, these events are connected not only with increased activist mobilisation, but also with great controversy, which is the case of Poland, where gay and lesbian marches have been attacked by right-wing protesters and cancelled by right-wing city authorities on a number of occasions. Overall, the scholars analysing these events have largely focused on the macro-context of the marches, paying less attention to the movement actors behind these events. The contribution of this thesis lies not only in filling a gap when it comes to research on sexual minorities in Eastern Europe/Poland, but also in its focus on micro-level movement processes and engagement with theories of collective identity and citizenship. Furthermore, this thesis challenges the inscription of Eastern European/Polish movements into the narrative of victimhood and delayed development when compared to LGBT movements in the Global North. This thesis is grounded in qualitative research including participant observation of public activist events as well as forty semi-structured interviews with the key organisers of gay and lesbian marches in Warsaw, Poznan and Krakow between 2001 and 2007, and five of these interviews were further accompanied by photo-elicitation (self-directed photography) methods. Starting from the processes whereby from 2001 onwards, marches, pride parades and demonstrations became the most visible and contested activity of the Polish lesbian and gay movement, this thesis examines how the activists redefined the meanings of citizenship in the post-transformation context, by incorporating the theme of sexual minorities' rights. Using Bernstein's (1997, 2002, 2005, 2008) concept of identity deployment, I show how and when movement actors use identity tactically, depending on their goals. Specifically, in the context of movement-media interactions, I examine the ways in which the activists use marches to challenge the negative representations of sexual minorities in Poland. I also broaden Bernstein's framework to include the discussion of emotion work as relevant to public LGBT activism in Poland. Later, I discuss how the emotions of protests allowed the activists to inscribe their efforts into the "revolutionary" narrative of the Polish Solidarity movement and by extension, the frame of citizenship. Finally, this thesis engages with the dilemmas of identity deployment strategies, and seeks to problematise the dichotomy between identity-based gay and lesbian assimilationist strategies and the anti-identity queer politics.
