Ontogenie und Phylogenie der Belemnitenart Hibolites jaculoides SWINNERTON, 1937, aus dem Hauterivium (Unterkreide) von NW-Deutschland (Sarstedt) und NE England (Speeton)

The belemnite species Hibolites jaculoides Swinnerton, 1937 is redefined on the basis of a bed by bed collection of 2100 rostrums from the Upper Hauterivian (Cretaceous deposits of NW Germany and Yorkshire, England. According to the variate-statistical evaluation of the data gathered, definite phylotic changes are disdernible within the species. All characters measured indicate a definite tendency towards reduction in size. Large-sized, club-shaped specimens are typical for the stratigraphically older beds, delicate and slender-built forms dominate in the upper Upper Hauterivian. Comparison of the material from England and Germany yielded that three of the varieties described by Swinnerton are limited mainly to the lower Upper Hauterivian of England.

Challenging masculinity in CSR disclosures:silencing of women’s voices in Tanzania’s mining industry

This paper presents a feminist analysis of corporate social responsibility (CSR) in a male-dominated industry within a developing country context. It seeks to raise awareness of the silencing of women’s voices in CSR reports produced by mining companies in Tanzania. Tanzania is one of the poorest countries in Africa, and women are often marginalised in employment and social policy considerations. Drawing on work by Hélène Cixous, a post-structuralist/radical feminist scholar, the paper challenges the masculinity of CSR discourses that have repeatedly masked the voices and concerns of ‘other’ marginalised social groups, notably women. Using interpretative ethnographic case studies, the paper provides much-needed empirical evidence to show how gender imbalances remain prevalent in the Tanzanian mining sector. This evidence draws attention to the dynamics faced by many women working in or living around mining areas in Tanzania. The paper argues that CSR, a discourse enmeshed with the patriarchal logic of the contemporary capitalist system, is entangled with tensions, class conflicts and struggles which need to be unpacked and acknowledged. The paper considers the possibility of policy reforms in order to promote gender balance in the Tanzanian mining sector and create a platform for women’s concerns to be voiced.

Efectos de una intervención educativa en la promoción de la actividad física, otros comportamientos saludables y los conocimientos para la prevención del cáncer de pulmón en jóvenes del colegio La Merced en Bogotá D.C., Colombia

Introducción: El cáncer de pulmón es el tipo de cáncer más mortal a nivel mundial, al cual se atribuyen una de cada cinco muertes anualmente. El objetivo de este estudio fue determinar los efectos de una intervención educativa en la promoción de la actividad física, otros comportamientos saludables y los conocimientos para la prevención del cáncer de pulmón en jóvenes estudiantes de una institución educativa pública en Bogotá, Colombia. Métodos: Estudio experimental no controlado en 243 estudiantes de sexo femenino (Edad 14±1,5 años). La intervención educativa se desarrolló en tres momentos: una sesión educativa con una duración de 60 minutos acorde a la Guía para la Comunicación Educativa en el Marco del Control del Cáncer, en Colombia. Segundo, se enviaron tres correos electrónicos con información acerca del cáncer pulmonar; finalmente se desarrollaron actividades grupales. Para la toma de datos se utilizaron el cuestionario Cáncer Awareness Measure (CAM) y el Sistema de Vigilancia de Factores de Riesgo del Comportamiento (BRFSS). La evaluación se realizó en un período de seguimiento a 1, 3 y 6 meses post-intervención. Resultados: La intervención educativa incrementó significativamente los conocimientos de las jóvenes sobre los signos de alarma del cáncer pulmonar y los principales factores de riesgo modificables, tales como el consumo de cigarrillo, la exposición al humo del mismo y el sedentarismo, al sexto mes post-intervención. Las mejoras en el cambio comportamental no lograron significancia estadística. Conclusiones: Una intervención educativa mejora los conocimientos acerca de la detección temprana y la prevención del cáncer de pulmón, así como los comportamientos saludables en jóvenes estudiantes en Bogotá, Colombia. Se requiere de estudios controlados aleatorizados.

Les Rendez-Vous de Chantal

Lo scopo di questa tesi vuole essere di dimostrare come Chantal Akerman abbia risposto concretamente all’appello di Laura Mulvey e delle altre teoriche della FFT per un contro-cinema femminile e lo abbia fatto principalmente attraverso tre strategie: la pratica di un cinema sperimentale e in particolare strutturale/minimalista di stampo newyorkese; la riscrittura di codici narrativi della Nouvelle Vague francese; l’espressione dei contenuti della teoria femminista e soprattutto di pensatrici come Hélène Cixous e Luce Irigaray.

Forma e critica del reale in Siegfried Kracauer (1925-1937): Immagine, citta, modernita

Siegfried Kracauer (1889-1966) fu di formazione ingegnere-architetto, giornalista. Egli fu un instancabile osservatore critico della superficie della realtà, convinto quale era che solo dall’osservazione dei fenomeni superficiali si potesse davvero intuire la realtà di un’epoca. L’obiettivo della tesi è cercare di cogliere il rapporto tra forma e critica della realtà attraverso saggi, articoli di giornale, recensioni di libri e film, biografie e autobiografie. All’interno di questo lavoro si sono isolate alcune immagini e opere che permettono, a nostro parere, di cogliere il senso della decifrazione della modernità in Kracauer. La luce come figura ambigua della fantasmagoria e della metropoli, il mito e la razionalizzazione capitalistica, la figura di Ginster, personaggio letterario chiaramente autobiografico incaricato di descrivere le tensioni nel passaggio dall’esperienza della prima guerra mondale al mondo moderno dell’improvvisazione e della perdita dei confini e, infine, Jacques Offenbach e l’operetta, incursione storica di Kracauer alla ricerca di una biografia sociale della città di Parigi come archeologia della modernità sviluppando un parallelo tra l’epoca del Secondo Impero di Napoleone III e l’avvento del nazismo. A ognuno di questi momenti è dedicato un capitolo che cerca di sviluppare continuità e discontinuità del pensiero di Kracauer nei confronti delle eredità filosofiche e metodologiche di György Lukács, Georg Simmel, Karl Marx. mL’attenzione è stata rivolta alle testimonianze dei rapporti e dei confronti, talora aspri, con i suoi colleghi e amici a partire da quelli complicati con Benjamin e Adorno che restituiscono un’immagine di un pensatore originale e complesso alla ricerca e, paradossalmente sulla soglia, di una via per pensare l’irruzione della cultura di massa e del potere assoggettante delle immagini.

Changes In Chromatin Structure In Nih 3t3 Cells Induced By Valproic Acid And Trichostatin A.

Valproic acid (VPA) and trichostatin A (TSA) are known histone deacetylase inhibitors (HDACIs) with epigenetic activity that affect chromatin supra-organization, nuclear architecture, and cellular proliferation, particularly in tumor cells. In this study, chromatin remodeling with effects extending to heterochromatic areas was investigated by image analysis in non-transformed NIH 3T3 cells treated for different periods with different doses of VPA and TSA under conditions that indicated no loss of cell viability. Image analysis revealed chromatin decondensation that affected not only euchromatin but also heterochromatin, concomitant with a decreased activity of histone deacetylases and a general increase in histone H3 acetylation. Heterochromatin protein 1-α (HP1-α), identified immunocytochemically, was depleted from the pericentromeric heterochromatin following exposure to both HDACIs. Drastic changes affecting cell proliferation and micronucleation but not alteration in CCND2 expression and in ratios of Bcl-2/Bax expression and cell death occurred following a 48-h exposure of the NIH 3T3 cells particularly in response to higher doses of VPA. Our results demonstrated that even low doses of VPA (0.05 mM) and TSA (10 ng/ml) treatments for 1 h can affect chromatin structure, including that of the heterochromatin areas, in non-transformed cells. HP1-α depletion, probably related to histone demethylation at H3K9me3, in addition to the effect of VPA and TSA on histone H3 acetylation, is induced on NIH 3T3 cells. Despite these facts, alterations in cell proliferation and micronucleation, possibly depending on mitotic spindle defects, require a longer exposure to higher doses of VPA and TSA.

Quantificação de fluxos de mercúrio gasoso na interface solo/atmosfera utilizando câmara de fluxo dinâmica: aplicação na bacia do Rio Negro

Gaseous mercury sampling conditions were optimized and a dynamic flux chamber was used to measure the air/surface exchange of mercury in some areas of the Negro river basin with different vegetal coverings. At the two forest sites (flooding and non-flooding), low mercury fluxes were observed: maximum of 3 pmol m-2 h-1 - day and minimum of -1 pmol m-2 h-1 - night. At the deforested site, the mercury fluxes were higher and always positive: maximum of 26 pmol m-2 h-1 - day and 17 pmol m-2 h-1 - night. Our results showed that deforestation could be responsible for significantly increasing soil Hg emissions, mainly because of the high soil temperatures reached at deforested sites.

Espectroscopia optogalvânica: alguns aspectos relevantes

In this work we present the optogalvanic effect in ionized gases in an historical perspective. This effect was observed for the first time by Foote and Mohler in 1925, and explained by Penning in 1928 for mixtures (Ne-Ar) and pure gases (or vapours) in 1937. Also, we show some aspects of the contributions of Romenian authors for the development of optogalvanic spectroscopy, which was used as a new technique only after 1964.

Ocorrência, comportamento e impactos ambientais provocados pela presença de antimicrobianos veterinários em solos

Antimicrobials, among other veterinary drugs, are used worldwide in industry and agriculture to protect animal health and prevent economic loss. In recent years, they have been detected in various environmental compartments, including soil, surface and groundwater and have become a topic of research interest. Emphasizing this class of compounds, this review presents the different pathways which veterinary drugs enter in the environment, in particular contaminate soils. Also are presented regulatory aspects and guidelines, adsorption/desorption and degradation of these compounds in soils and the consequences of its dispersal in the environment.
