Implicações políticas da cooperação internacional para o desenvolvimento em Moçambique: da solidariedade socialista à trajetória tradicional do norte e à experiência emergente do sul (1975-2013)

Esta Tese examina as implicações políticas da cooperação internacional para o desenvolvimento de Moçambique em três momentos: (i) o período referente à solidariedade socialista; (ii) o contexto da cooperação tradicional Norte-Sul; (iii) a experiência (re) emergente da Cooperação Sul-Sul. Nossa incursão analítica mostra que foram cerca de 40 anos de cooperação internacional que permitiram uma série de transformações em nível político, econômico e social, e que construíram um país como um autêntico artefato de intervenção externa. Nesse sentido, analisam-se os efeitos políticos provocados pelas três propostas sugeridas de cooperação na esfera doméstica de Moçambique. Por um lado, constata-se que a cooperação internacional acaba por constituir-se em projeto de poder que afeta a produção de políticas públicas, a construção da autonomia e, mais recentemente, o processo de democratização em curso. Por outro, evidencia-se que os atores internacionais que atuam no campo da cooperação para o desenvolvimento em Moçambique agem imbuídos de seus respectivos interesses e agendas de política externa. Na relação entre os distintos atores e o Estado moçambicano, identificam-se alguns fatores-chave, tais como a fraca capacidade estatal, a existência de enormes assimetrias entre Moçambique e seus parceiros, o vício em receber cooperação que transforma essa relação em uma das principais fontes de manutenção do Estado, bem como a preservação das elites políticas tradicionais fatores que limitam o alcance dos objetivos reais de desenvolvimento que as distintas formas e modalidades de cooperação internacional prometem e buscam promover.

Efeitos tardios no tecido ovariano de ratas Wistar após tratamento com Docetaxel e Ciclofosfamida

O câncer de mama (CM) é o segundo tipo de câncer mais comum no mundo. Sabe-se que a maior incidência de CM ocorre nas mulheres pós-menopausa, entretanto é crescente o número de mulheres jovens acometidas por esta doença. O tratamento do CM pode incluir: quimioterapia, radioterapia e/ou hormonioterapia. A quimioterapia, por se ser um tratamento sistêmico, pode causar importantes efeitos colaterais, entre eles a falência ovariana induzida por quimioterapia (FOIQ). As principais consequências da FOIQ são a infertilidade, além de complicações tardias relacionadas à diminuição do estrogênio, como a osteoporose e doenças cardiovasculares. O regime quimioterápico TC, adota a associação do docetaxel com a ciclofosfamida, como uma opção por fármacos que resultem numa taxa de sobrevida livre do câncer, e menores efeitos colaterais. Este trabalho teve como objetivo estudar os efeitos tardios no ovário causados pelo tratamento com a associação dos quimioterápicos docetaxel e ciclofosfamida (TC), em modelo animal com ratos Wistar. Para verificar o sinergismo desses quimioterápicos e assim analisar o efeito da administração conjunta, ratos Wistar fêmeas foram divididos em dois grupos: um grupo controle e um grupo que recebeu quimioterapia (TC). Os animais foram submetidos a eutanasia cinco meses após o fim do tratamento, e foram recolhidos o plasma e os ovários. Foram observadas alterações importantes. O nível de estradiol no plasma foi significativamente reduzido no grupo de TC em comparação com o grupo controle. Além disso, o número de núcleos apoptóticos foi maior no grupo TC. O papel da resposta inflamatória no desenvolvimento da lesão ovariana foi também investigado, e notou-se um aumento do número de mastócitos, e aumento da expressão de Fator de Necrose Tumoral-α (TNF-α) no grupo TC. O envolvimento de fibrose nesse processo, foi também investigado. Os resultados mostraram que níveis de expressão de Fator de Crescimento Tumoral-β1 (TGF-β1), Colágeno Tipo I (Col-I) e Colágeno Tipo III (Col-III) estavam maiores no grupo TC em comparação com o grupo de controle. A análise ultraestrutural revelou a presença de feixes de colágeno no grupo tratado, e mostrou que a arquitetura do tecido do ovário estava mais desorganizada neste grupo comparado ao grupo controle. Os resultados obtidos neste trabalho indicam que a combinação de ciclofosfamida e docetaxel, um recente regime quimioterápico proposto para o tratamento do CM, pode levar a importantes alterações no ovário. O processo inflamatório, desencadeado pela administração dos quimioterápicos, estimula a apoptose e liberação de TGF-β no estroma ovariano, que induz a produção de matriz extracelular e subsequente, substituição do tecido sadio por tecido fibrótico. A principal consequência deste processo é a diminuição, ou perda, da função ovariana, levando à menopausa precoce e possível infertilidade. É importante compreender os mecanismos envolvidos na infertilidade provocada pelo regime TC, a fim de estudar novos métodos que evitem este efeito indesejável em mulheres submetidas a tratamento do CM.

Elevating fishers of Dal Lake in Jammu and Kashmir

The deteriorating condition of one of the most magnificent lakes of India, the Dal Lake, has provoked a lot of research interest from the biological and ecological points of view. However, the impact of deterioration of the ecology on the inhabitant fisher folk around Dal Lake has not been given much importance. In this study, the three major beats of the lake, namely, Hazratbal, Nishat and Nehru Park, were surveyed, randomly taking 10% of the fishermen families. It was observed that the summer mean catch per day (5.18 ± 0.69 kg) was more than the mean winter catch per day (2.85 ± 0.40 kg). However, the total annual catch per person was only 1195.56 ± 211.63 kg. Moreover, marketing through middlemen, especially, during summer, was observed to be very low fetching in terms of mean price per kilogram fish, amounting to Rs 37.50 ± 2.54 for local fish and Rs 22.50 ± 2.88 for the carp. It was also observed that the fisher folk had borrowed a good amount of money for the repair and construction of their houses and boats. Therefore, on the whole, the fishing business around Dal Lake was observed to be under severe stress. In this context, this paper has come out with recommendations to uplift the socio-economic conditions of the fishers.

IgM, IgD and IgY and their expression pattern in the Chinese soft-shelled turtle Pelodiscus sinensis

Three Ig isotypes, IgM, IgD, and IgA, were previously known in reptiles. Here, in this report we describe IgM, IgD and a novel immunoglobulin heavy-chain isotype upsilon (IgY) in Chinese soft-shelled turtle (Pelodiscus sinensis). The IgM and IgY constant domains are characteristically similar to their counterparts described in other vertebrates. The expression of IgM and IgD were detected at mRNA level early during embryonic development, and their expression increased during further development. However, the IgY expression was not detected in larval turtles until 90 days after hatching-out. The increase in the transcription of these three Ig molecules was analyzed by using real-time PCR in spleen, kidney and blood following the injection of inactivated Aeromonas hydrophila. The primary increase in the expression of these three Igs was observed I week after the first injection, although not statistically significant, and the second injection 2 weeks after the first injection provoked a significant increase in the expression of these Igs, revealing a pattern of primary and secondary antibody response in the turtle. The present study represents the first report on reptile IgY and the pattern of IgM, IgD and IgY transcription in reptiles. (C) 2009 Elsevier Ltd. All rights reserved.

Physiological and immune responses of zhikong scallop Chlamys farreri to the acute viral necrobiotic virus infection

The Zhikong Scallop, Chlamys farreri, is one of the most Important bivalve mollusks cultured in northern China However, mass mortality of the cultured C farreri has posed a serious threat to the maricultural Industry in recent years. Acute Viral Necrobiotic Virus (AVNV) is believed as an important etiological agent causing the scallop mass mortalities To understand the mechanism behind the AVNV associated scallop disease and mortality, we assessed the physiological and immune responses of C farreri to the virus infection using oxygen consumption rate, ammonium-nitrogen excretion rate, hemocyte copper, zinc superoxide dismutase gene expression, and plasma superoxide dismutase activity and alkaline phosphatase activity as indicators Scallops challenged by AVNV at 25 C developed typical disease signs 2 days after virus injection Before the disease manifested, scallop oxygen consumption and NH4+-N excretion rates rose and then fell back. Real-time PCR revealed that the hemocyte cytosol Cu, Zn SOD gene expression was upregulated followed by recovery The plasma SOD activity, however, augmented consistently following virus injection Moreover, plasma AKP activity first lowered and then elevated gradually to the highest level at 24 h post virus injection Scallops challenged by AVNV at 17 degrees C neither developed notable disease nor showed obvious responses that could be associated with the virus infection. While the results suggested a correlation between the elevated seawater temperature and the AVNV infection associated C farreri mortalities, they also indicated that the viral infection provoked multiple physiological and immune responses in the host scallops (C) 2010 Elsevier Ltd All rights reserved

Antysemicki incydent prasowy. Kartki pocztowe i poznańskie gazety

Jednym z motywów ikonograficznych wykorzystywanych na reklamowych kartach pocztowych z przełomu XIX i XX wieku były strony tytułowe lokalnych gazet. Wokół poznańskich pocztówek z motywem „gazetowym” wydawanych przez Isaaka Plessnera wybuchła w 1904 roku polemika prasowa o silnie antysemickim podłożu. Zarzut dotyczył druku reklamy katolickiego czasopisma u żydowskiego wydawcy.

Particulate allergens potentiate allergic asthma in mice through sustained IgE-mediated mast cell activation.

Allergic asthma is characterized by airway hyperresponsiveness, inflammation, and a cellular infiltrate dominated by eosinophils. Numerous epidemiological studies have related the exacerbation of allergic asthma with an increase in ambient inhalable particulate matter from air pollutants. This is because inhalable particles efficiently deliver airborne allergens deep into the airways, where they can aggravate allergic asthma symptoms. However, the cellular mechanisms by which inhalable particulate allergens (pAgs) potentiate asthmatic symptoms remain unknown, in part because most in vivo and in vitro studies exploring the pathogenesis of allergic asthma use soluble allergens (sAgs). Using a mouse model of allergic asthma, we found that, compared with their sAg counterparts, pAgs triggered markedly heightened airway hyperresponsiveness and pulmonary eosinophilia in allergen-sensitized mice. Mast cells (MCs) were implicated in this divergent response, as the differences in airway inflammatory responses provoked by the physical nature of the allergens were attenuated in MC-deficient mice. The pAgs were found to mediate MC-dependent responses by enhancing retention of pAg/IgE/FcεRI complexes within lipid raft–enriched, CD63(+) endocytic compartments, which prolonged IgE/FcεRI-initiated signaling and resulted in heightened cytokine responses. These results reveal how the physical attributes of allergens can co-opt MC endocytic circuitry and signaling responses to aggravate pathological responses of allergic asthma in mice.

Spaces of observation and obscurity: cinematic prisons of light and dark

In The Eye of Power, Foucault delineated the key concerns surrounding hospital architecture in the latter half of the eighteenth century as being the ‘visibility of bodies, individuals and things'. As such, the ‘new form of hospital' that came to be developed ‘was at once the effect and support of a new type of gaze'. This was a gaze that was not simply concerned with ways of minimising overcrowding or cross-contamination. Rather, this was a surveillance intended to produce knowledge about the pathological bodies contained within the hospital walls. This would then allow for their appropriate classification. Foucault went on to describe how these principles came to be applied to the architecture of prisons. This was exemplified for him in the distinct shape of Bentham's panopticon. This circular design, which has subsequently become an often misused synonym for a contemporary culture of surveillance, was premised on a binary of the seen and the not-seen. An individual observer could stand at the central point of the circle and observe the cells (and their occupants) on the perimeter whilst themselves remaining unseen. The panopticon in its purest form was never constructed, yet it conveys the significance of the production of knowledge through observation that became central to institutional design at this time and modern thought more broadly. What is curious though is that whilst the aim of those late eighteenth century buildings was to produce wellventilated spaces suffused with light, this provoked an interest in its opposite. The gothic movement in literature that was developing in parallel conversely took a ‘fantasy world of stone walls, darkness, hideouts and dungeons…' as its landscape (Vidler, 1992: 162). Curiously, despite these modern developments in prison design, the façade took on these characteristics. The gothic imagination came to describe that unseen world that lay behind the outer wall. This is what Evans refers to as an architectural ‘hoax'. The façade was taken to represent the world within the prison walls and it was the façade that came to inform the popular imagination about what occurred behind it. The rational, modern principles ordering the prison became conflated with the meanings projected by and onto the façade. This confusion of meanings have then been repeated and reenforced in the subsequent representations of the prison. This is of paramount importance since it is the cinematic and televisual representation of the prison, as I argue here and elsewhere, that maintain this erroneous set of meanings, this ‘hoax'.

Intracellular fate of bioresponsive poly(amidoamine)s in vitro and in vivo

Linear poly(amidoamine)s (PAAs) have been designed to exhibit minimal non-specific toxicity, display pH-dependent membrane lysis and deliver genes and toxins in vitro. The aim of this study was to measure PAA cellular uptake using ISA1-OG (and as a reference ISA23-OG) in B16F10 cells in vitro and, by subcellular fractionation, quantitate intracellular trafficking of (125)I-labelled ISA1-tyr in liver cells after intravenous (i.v.) administration to rats. The effect of time after administration (0.5-3h) and ISA1 dose (0.04-100mg/kg) on trafficking, and vesicle permeabilisation (N-acetyl-b-D-glucosaminidase (NAG) release from an isolated vesicular fraction) were also studied. ISA1-OG displayed approximately 60-fold greater B16F10 cell uptake than ISA23-OG. Passage of ISA1 along the liver cell endocytic pathway caused a transient decrease in vesicle buoyant density (also visible by TEM). Increasing ISA1 dose from 10mg/kg to 100mg/kg increased both radioactivity and NAG levels in the cytosolic fraction (5-10 fold) at 1h. Moreover, internalised ISA1 provoked NAG release from an isolated vesicular fraction in a dose-dependent manner. These results provide direct evidence, for the first time, of PAA permeabilisation of endocytic vesicular membranes in vivo, and they have important implications for potential efficacy/toxicity of such polymeric vectors.

Un episodio en la recepción cultural dieciochesca de lo exótico: la llegada del elefante a Madrid en 1773

At the end of 1773 an Indian elephant, brought for the royal ménagerie at Aranjuez, was shown in the streets of Madrid. The resulting public fascination provoked by the intrusion of this exotic animal can be traced through poems (Tomás de Iriarte), short plays (Ramón de la Cruz), articles in the periodical press, popular and scientific prints representing the animal, and even in the costumbrista pastels of Lorenzo Tiepolo. The mythic and premodern knowledge of animal nature collides in a debate with the new scientific observation. In the final decades of the 18th century, the image of the captive elephant acquired in Europe a new symbolic meaning linked with the political fight against slavery. All these very different elements converge in Goya's Disparate de bestia.

A Triumph of Voluntarism? Industrial Relations and Strikes in Northern Ireland During World War Two

Flanders (1974) considered the Second World War to be the great social triumph and vindication of voluntarism in British industrial relations. This paper considers the experience of one region, Northern Ireland, functioning in a unique social and political context and considers the experience of its wartime industrial relations system. The political framework, trade union growth and representation, collective bargaining, strike activity including the major munitions strike of 1944 which may have provoked Defence Regulations Order 1AA, labour management and Joint Production Committees are all examined. The paper gives qualified support to Flanders’ conclusion.

“The new Cagliostro”: Onofroff, Rubén Darío and his story "La esfinge"

The article retraces the career of the famous hypnotist Onofroff and particularly his visit to Buenos Aires, where his activity, in 1895, provoked many discussions and some public embarrassment. In this context Darío, using a pseudonym, published his crónica “La esfinge”. We reproduce “La esfinge”, transcribing the original text of La Nación, with annotations identifying the literary and theosophical sources Darío used when he wrote it.

Using time-to-contact information to assess potential collision modulates both visual and temporal prediction networks

Accurate estimates of the time-to-contact (TTC) of approaching objects are crucial for survival. We used an ecologically valid driving simulation to compare and contrast the neural substrates of egocentric (head-on approach) and allocentric (lateral approach) TTC tasks in a fully factorial, event-related fMRI design. Compared to colour control tasks, both egocentric and allocentric TTC tasks activated left ventral premotor cortex/frontal operculum and inferior parietal cortex, the same areas that have previously been implicated in temporal attentional orienting. Despite differences in visual and cognitive demands, both TTC and temporal orienting paradigms encourage the use of temporally predictive information to guide behaviour, suggesting these areas may form a core network for temporal prediction. We also demonstrated that the temporal derivative of the perceptual index tau (tau-dot) held predictive value for making collision judgements and varied inversely with activity in primary visual cortex (V1). Specifically, V1 activity increased with the increasing likelihood of reporting a collision, suggesting top-down attentional modulation of early visual processing areas as a function of subjective collision. Finally, egocentric viewpoints provoked a response bias for reporting collisions, rather than no-collisions, reflecting increased caution for head-on approaches. Associated increases in SMA activity suggest motor preparation mechanisms were engaged, despite the perceptual nature of the task.

The Perils of Moviegoing in America, 1896-1950

The Perils of Moviegoing in America is a film history that examines the various physical and (perceived) moral dangers facing audiences during the first fifty years of film exhibition.

Chapter 1: “Conflagration”
As early as 1897, a major fire broke out at a film exhibition in San Francisco, with flames burning the projectionist and nearby audience members. From that point until the widespread adoption of safety stock in 1950, fires were a very common movie-going experience. Hundreds of audience members lost their lives in literally thousands of theatre fires, ranging from early nickelodeons to the movie palaces of the thirties and forties.

Chapter 2: “Thieves Among Us”
Bandits robbed movie theatres on hundreds of occasions from the early days of film exhibition through the end of the Great Depression. They held up ticket booths, and they dynamited theatre safes. They also shot theatre managers, ushers, and audience members, as a great many of the robberies occurred while movies were playing on the screens inside.

Chapter 3: “Bombs Away”
Bombings at movie theatres became common in small towns and large cities on literally hundreds of occasions from 1914 to the start of World War II. Some were incendiary bombs, and some were stench bombs; both could be fatal, whether due to explosions or to the trampling of panicked moviegoers

Chapter 4: “It’s Catching”
Widespread movie-going in the early 20th century provoked an outcry from numerous doctors and optometrists who believed that viewing films could do irreparable harm to the vision of audience members. Medical publications (including the Journal of the American Medical Association) published major studies on this perceived problem, which then filtered into popular-audience magazines and newspapers.

Chapter 5: “The Devil’s Apothecary Shops”
Sitting in the dark with complete strangers proved worrisome for many early filmgoers, who had good reason to be concerned. Darkness meant that prostitutes could easily work in the balconies of some movie theatres, as could “mashers” who molested female patrons (and sometimes children) after the lights were dimmed. That was all in addition to the various murderers who used the cover of darkness to commit their crimes at movie theatres.

Chapter 6: “Blue Sundays”
Blue laws were those regulations that prohibited businesses from operating on Sundays. Most communities across the US had such legislation on their books, which by the nickelodeon era were at odds with the thousands of filmgoers who went to the movies every Sunday. Theatre managers were often arrested, making newspaper headlines over and over again. Police sometimes even arrested entire film audiences as accomplices in the Blue Law violations.

Chapter 7: “Something for Nothing”
In an effort to bolster ticket sales, many movie theatres in the 1910s began to hold lotteries in which lucky audience members won cash prizes; by the time of the Great Depression, lotteries like “Bank Night” became a common aspect of the theatre-going enterprise. However, reception studies have generally overlooked the intense (and sometimes coordinated) efforts by police, politicians, and preachers to end this practice, which they viewed as illegal and immoral gambling.
