Cinema = cavação: Cendroswald produções cinematográficas

Em 1924, Blaise Cendrars, em meio a um projeto ambicioso de realização de um “filme de propaganda sobre o Brasil”, em parceria com Oswald de Andrade, teve a oportunidade de testemunhar a eclosão da Revolução de 1924, reprimida com violência pelo governo federal. A experiência marcou a sua imaginação e sepultou os planos de realizar um filme no Brasil, baseado em episódios da história paulista. Um dos elementos que aproximaram Oswald e Cendrars foi o desejo comum de se tornarem cineastas-cavadores

Trends in South American weapons purchases at the beginning of the new millennium

In recent years, with some frequency it is heard that Latin America, especially South America, is witnessing the rise of an arms race. Frequent reports in the press and strong statements made by politicians in the region have fueled this fear. At the same time, scholars have also reached to this conclusion, as pointed out by Malamud and Garcia: "The famous arms race in Latin America, led by Venezuela, is no longer just talk."

Abbandono del territorio e dissesto idrogeologico in Appennino bolognese: analisi delle dinamiche e degli interventi di gestione idraulico-forestale

The abandonment of less productive fields and agro-forest activities has occured in the last decades, interesting large mountain areas in all mediterranean basin. Until the fifties, agricultural practices dealt mainly with soil surface and surface runoff control systems. However, the apparent sustainability of soil use results often in contrast with historical documents, witnessing heavy hydrogeological instability, in naturally fragile areas. The research focused on the dynamics and effects of post-coltural land abandonment in a critical mountain area of the Reno River. The Reno River rappresents a typical Tuscan-Emilian Apennines Watershed where soil erosion occurs under very different conditions depending on interactions between land use, climate, geomorphology and lithology. Landslides are largely rappresented, due to the diffusion of clay hill slopes. Recent researches suggest that climatic variability will increase as a consequence of global climate change, resulting in greater frequency and intensity of extreme weather events, which could increase rates of erosion, landslides reactivations and diffusion of calanchive basins. As far as hill slopes are concerned, instability is today basically due to intrinsic factors, as the Apennine range is a rather young formation, in geological terms, and is mainly formed by sedimentary rocks with high occurrence of clays. Therefore landslides and rockfalls are very frequent, while surface soil erosion is generally low and anyway concentrated in the low Apennine, where intensive farming is still economically worth. The study, supported by GIS use, analyses the main fisical characteristics of the area and the historical changes of land use, and focalizes the dynamics of spontaneous reafforestation. Futhermore, the research studies the results of soil bioengineering and surface water control solutions for the restablishment of landslides occured in the last period. Infact soil bioengineering has been recently used in different situations in order to consolidate slopes and hillsides and prevent erosion; when applied, it gave good results, both in terms of engineering efficiency and vegetational development, expecially if combined with a good hydraulic control, thus proving to be an actual alternative to other techniques with heavier environmental impacts. Research into the specific site features and the use of proper plant species is vital to the success of bioengineering works.

Il giudice tributario come giudice europeo

Questo lavoro, tramite un'analisi attenta ed accurata dello sviluppo delle pronunce della Corte di Giustizia in materia tributaria, ha lo scopo di mettere in evidenza i canoni interpretativi utilizzati dalla Corte, tenendo presente gli effetti che tali pronunce hanno prodotto nei singoli stati ed in particolare sul ruolo del giudice tributario come giudice europeo. Assistiamo infatti oggi ad una vera e propria europeizzazione della produzione giuridica in grado di aprire nuovi spiragli alla tutela del cittadino anche nei confronti dell'amministrazione finanziaria. L'interazione, per molti aspetti problematica, tra gli organi di giustizia tributaria dei singoli ordinamenti ed il giudice comunitario sono diventate vera e propria fucina di un diritto tributario europeo, nell'ambito del quale a svolgere un ruolo di estrema rilevanza è il giudice interno. Le sentenze del giudice tributario nazionale infatti rappresentano lo strumento più efficace di chiarificazione del diritto comunitario. Il presente lavoro si propone quindi di esaminare nel dettaglio il rapporto complementare e funzionalista che si estrinseca nella peculiare funzione attribuita al giudice tributario nazionale che gli fa assumere le vesti di "giudice europeo" nonché la funzione attribuita alla Corte di Giustizia che assume i caratteri sempre più marcati di "giudice tributario sovranazionale". Partendo dalla disamina delle figure dei giudici tributari di Germania, Francia ed Italia, si passerà poi ad evidenziare i ruoli che hanno avuto le Corti nazionali nell'applicazione del diritto comunitario, evidenziando come nei vari casi le sentenze si sono affiancate alla preminenza gerarchica della norma europea.

Youth at Risk: Part 1, 2012 Massachusetts Family Impact Seminar

The youth of Massachusetts are of primary concern to legislators and citizens. This briefing report features three essays by experts – Lisa Jones, Ramon Borges-Mendez, and Janis Wolak – who focus on three aspects of youth wellbeing: youth victimization and other indicators of psychological health, youth unemployment, and online sexual predators of youth. Although youth well-being is of primary concern, the worrisome stories about crimes against children that regularly fill the media have unfortunately obscured some more positive news from statistical reports on these same issues. Child victimizations of various types – i.e., child sexual abuse, witnessing domestic violence, child physical abuse, sexual assaults of teenagers, physical assaults and robberies of teenagers, and homicides of teenagers – have been declining nationwide and in Massachusetts since the early 1990s, in some cases declining dramatically.

Beyond the Pro and Contra of Evidence-Based Practice: Reflections on a Recurring Dilemma at the Core of Social Work

Currently, social work is witnessing a quite polarized debate about what should be the basis for good practice. Simply stated, the different attempts to define the required basis for effective and accountable interventions in social work practice can be grouped in two paradigmatic positions, which seem to be in strong opposition to each other. On the one hand the highly influential evidence based practice movement highlights the necessity to base practice interventions on proven effectiveness from empirical research. Despite some variations, such as between narrow conceptions of evidence based practice (see e.g. McNeece/Thyer, 2004) and broader approaches to it (see e.g. Gambrill, 1999, 2001, 2008), the evidence based practice movement embodies a positivist orientation and more explicitly scientific aspirations of social work by using positivistic empirical strategies. Critics of the evidence based practice movement argue that its narrow epistemological assumptions are not appropriate for the understanding of social phenomena and that evidence based guidelines to practice are insufficient to deal with the extremely complex activities social work practice requires in different and always somewhat unique practice situations (Webb, 2001; Gray & Mc Donald, 2006; Otto, Polutta &Ziegler, 2009). Furthermore critics of evidence based practice argue that it privileges an uncritical and a-political positivism which seems highly problematic in the current climate of welfare state reforms, in which the question ‘what works’ is highly politicized and the legitimacy of professional social work practice is being challenged maybe more than ever before (Kessl, 2009). Both opponents and proponents of evidence based practice argue on the epistemological, the methodological and the ethical level to sustain their point of view and raise fundamental questions about the real nature of social work practice, so that one could get the impression that social work is really at the crossroads between two very different conceptions of social work practice and its further professional development (Stepney, 2009). However, this article is not going to merely rehearse the pro and contra of different positions that are being invoked in the debate about evidence based practice. Instead it aims to go further by identifying the dilemmas underlying these positions which - so it is argued – re-emerge in the debate about evidence based practice, but which are older than this debate. They concern the fundamental ambivalence modern professionalization processes in social work were subjected to from their very beginnings.

Skolemization for Substructural Logics

The usual Skolemization procedure, which removes strong quantifiers by introducing new function symbols, is in general unsound for first-order substructural logics defined based on classes of complete residuated lattices. However, it is shown here (following similar ideas of Baaz and Iemhoff for first-order intermediate logics in [1]) that first-order substructural logics with a semantics satisfying certain witnessing conditions admit a “parallel” Skolemization procedure where a strong quantifier is removed by introducing a finite disjunction or conjunction (as appropriate) of formulas with multiple new function symbols. These logics typically lack equivalent prenex forms. Also, semantic consequence does not in general reduce to satisfiability. The Skolemization theorems presented here therefore take various forms, applying to the left or right of the consequence relation, and to all formulas or only prenex formulas.

Von der Bezeugung zur narrativen Vergegenwärtigung. Fokalisierung im Reisebuch des Syrers Ḥanna Dyāb (1764)

Travelogues involve different truth claims, depending on whether their authors attempt on the one hand to convey received knowledge about entities and places, or on the other hand, present accounts of the traveler character’s own experiences. This study focuses on a travelogue from 1764 written by the Arabian Nights’ Syrian storyteller, Ḥanna Dyāb. Having written his travelogue more than 50 years after his trip to Paris, he evidently conceived of his narrative as a means to re-enact his experiences as a young traveler. To describe his particular self-staging in this autodiegetic narration “before fiction” (Paige 2011), I argue that an understanding of focalization as a graded visual mediation between the character’s inner life and the reader is needed. This approach helps one grasp how, with reference to Dyāb’s travelogue, truth is not something the traveler witnesses, but rather something the reader is invited to realize. I conclude that, with this shift from witnessing to visualization (Vergegenwärtigung), Dyāb’s travelogue fulfills a core function of literature.

Comparison of telomere length in black and white teachers from South Africa: the sympathetic activity and ambulatory blood pressure in Africans study

OBJECTIVE Telomere length is a marker of biological aging that has been linked to cardiovascular disease risk. The black South African population is witnessing a tremendous increase in the prevalence of cardiovascular disease, part of which might be explained through urbanization. We compared telomere length between black South Africans and white South Africans and examined which biological and psychosocial variables played a role in ethnic difference in telomere length. METHODS We measured leukocyte telomere length in 161 black South African teachers and 180 white South African teachers aged 23 to 66 years without a history of atherothrombotic vascular disease. Age, sex, years having lived in the area, human immunodeficiency virus (HIV) infection, hypertension, body mass index, dyslipidemia, hemoglobin A1c, C-reactive protein, smoking, physical activity, alcohol abuse, depressive symptoms, psychological distress, and work stress were considered as covariates. RESULTS Black participants had shorter (median, interquartile range) relative telomere length (0.79, 0.70-0.95) than did white participants (1.06, 0.87-1.21; p < .001), and this difference changed very little after adjusting for covariates. In fully adjusted models, age (p < .001), male sex (p = .011), and HIV positive status (p = .023) were associated with shorter telomere length. Ethnicity did not significantly interact with any covariates in determining telomere length, including psychosocial characteristics. CONCLUSIONS Black South Africans showed markedly shorter telomeres than did white South African counterparts. Age, male sex, and HIV status were associated with shorter telomere length. No interactions between ethnicity and biomedical or psychosocial factors were found. Ethnic difference in telomere length might primarily be explained by genetic factors.

History of Maltreatment and Psychiatric Impairment in Children in Outpatient Psychiatric Treatment

There is increasing evidence that childhood victimization and attachment disruptions impact a child’s development. In this study, children and adolescents from an outpatient psychiatric clinic were assessed, measuring history of trauma, history of out-of-home placement, initial diagnoses, and CBCL internalizing and externalizing problem scores. Multiple regression analyses showed that both violent abuse trauma (physical/sexual abuse) and victim trauma (physical abuse/sexual abuse/witnessing domestic violence/witnessing community violence) are prevalent among patients with externalizing severity problems; concluding that diagnosis alone may not account for a history of victimization, but externalizing problem severity does. Overall, the study is consistent with past literature that it is important to acknowledge a child’s history of maltreatment and out-of-home placement when understanding their psychiatric development and diagnosis.

Disposiciones espaciales y valorización del capital. El caso de Nordelta

Asistimos a la ampliación de "...una lógica estrictamente capitalista en el desarrollo metropolitano, otorgando a la plusvalía urbana el rango de criterio urbanístico básico" (de Mattos, 2002:1). El gobierno del Estado se reemplaza por la gobernancia y el sector privado revaloriza su rol como constructor y decisor, el Estado se repliega y el capital encuentra nuevos nichos para valorizarse. La redefinición normativa y la gestión privada alteran la propiedad constitutiva de la ciudad como valor de uso complejo (Topalov, 1979). El capital aprende a valorizarse adquiriendo un control parcial sobre derechos, servicios y bienes públicos, y produciendo elementos urbanos que antes le resultaban irreproducibles. Así, la planificación de la ciudad y la comercialización de un nuevo estilo de vida para los sectores privilegiados deviene en una nueva forma de valorización del capital. ¿Pueden los agentes inmobiliarios por sí solos crear mundos de la vida (Habermas, 1987), en su doble concepción de espacios de sociabilidad y horizonte de apreciación, y asegurarse consumidores? El megaemprendimiento toma cuerpo en los estilos de vida de sus habitantes; una metamorfosis sufrida en sus disposiciones y competencias espaciales reorganiza el sentido de sus prácticas y representaciones territoriales. Los habitus (Bourdieu, 1997) se conforman junto a la nueva espacialidad como estructura estructurada por emprendimientos como Nordelta y como estructura estructurante de los nuevos objetos urbanos. Es decir, los habitus no resultan de la impresión mecánica de las estructuras sociales capitalistas sino que se constituyen en un complejo proceso irreducible a las dicotomías entre objetivismo-subjetivismo, acción-estructura, etc. Las disposiciones y competencias espaciales pueden pensarse como la articulación del par dialéctico que presenta Santos (1996) al referirse al espacio geográfico como un conjunto de sistemas de objetos y sistemas de acciones, considerados como el contexto único en el que se realiza la historia.

Onset of long-term cooling of Greenland near the Eocene-Oligocene boundary as revealed by branched tetraether lipids

The Eocene-Oligocene (E-O) boundary interval is considered to be one of the major transitions in Earth's climate, witnessing the first major expansion of the East Antarctic Ice Sheet. However, the extent of the associated climatic cooling, especially for high northern latitude continental landmasses, is poorly constrained. In this study we reconstruct the first mean annual air temperature (MAAT) for the Greenland landmass during the late Eocene and early Oligocene by applying a new proxy based on the distribution of branched tetraether lipids derived from soil bacteria preserved in a marine sediment core from the Greenland Basin. The temperature estimates are compared with a composite continental temperature record based on bio-climatic analysis of pollen assemblages. Both proxies reveal comparable late Eocene MAATs of ~13-15 °C and a gradual long-term cooling of ~3-5 °C starting near the E-O boundary. These data are in agreement with other MAAT reconstructions from northern midlatitude continents and suggest a general cooling of the Northern Hemisphere during the E-O transition.
