A Ilha Anchieta está localizada no litoral norte do Estado de São Paulo, no município de Ubatuba. Um importante sítio que apresenta em seu passado a presença de uma prisão, que perpassou múltiplas formas de encarceramento entre 1908-1955. O escopo da presente dissertação restringe-se ao período entre 1942-1955, quando era denominada Instituto Correcional da Ilha Anchieta (ICIA), tendo como momento de inflexão e reflexão uma grande rebelião prisional ocorrida em 20 de junho de 1952. A partir das pesquisas etnográfica, documental e bibliográfica realizadas, procurei entender, principalmente, como eram organizadas as redes de sociabilidade entre militares, funcionários civis, mulheres, crianças e os indivíduos privados da liberdade, que lá se encontravam encarcerados e ilhados. Durante o percurso historiográfico e micro sociológico, as relações foram sendo reveladas no plano das práticas cotidianas em escalas e perspectivas distintas, mas congruentes, que passaram a ser descritas, revelando uma intrincada malha de sociabilidade que misturava interesses e agentes variados, uma minuciosa trama de conflitos e dinâmicas sociais. O que está em voga são as fronteiras que operam nos momentos de interação social, subdivididas em cotidiano e rebelião, de como as dinâmicas sociais de um sujeito denominado Ilha Anchieta operam com a população residente e observar, principalmente, a dicotomia entre margens e Estado. A pesquisa permitiu ver como os indivíduos e as categorias operavam tanto no cotidiano, quanto no momento de evento crítico, de rebelião, levando-me a afirmar que, em momentos de ruptura, há um deslaçamento das dinâmicas previamente construídas para, no momento da ruptura, os indivíduos retornarem discursiva e praticamente às suas esferas categóricas de pertencimento, levando-me a crer que é no cotidiano e nas dinâmicas do dia a dia que as formas de nomeação e conceitualização, usualmente marginalizadas, entrelaçam-se tanto para dentro, como para fora do Estado. Desse choque surgem possibilidades de análise dos conflitos, contextos políticos e seus desdobramentos na história do sistema prisional paulista.

This is the first Annual report of the Cumberland River Authority on information of its activities and responsibilities on river management in its area between the beginning of April 1965, to the end of March 1966. The report contains 5 main sections on water resources, land drainage, fisheries, pollution, and finally the expenditure and income for the 12 month period. The first area that the report deals with is water resources, which includes periodical surveys, hydrometric schemes, acceptable flows, conservation works and a review of rainfall and river flow. The section on land drainage looks at work on improvement schemes, floods, charges and information on maintenance work carried out on rivers including Wampool, Waver, Marron, Irt, Esk, Eden, Caldew, Petteril, Eamont and Annas. The fisheries section covers 5 districts of the River Eden, Esk, Ellen, Derwent, and South West Cumberland. It includes angling information and a general report for salmon and sea trout, brown trout and freshwater fish. It also looks at fish hatchery, fisheries protection and byelaws including licence numbers issued for the different districts. The fourth section on pollution deals with water quality of the rivers and their tributaries from the same 5 areas mentioned above. It also covers information on sewage and trade effluents. The River Authorities preceded the Environment Agency which came into existence in 1996.

This is the River Exe Fisheries Survey 1966-1967 by the Devon River Authority. This is the fifth Fisheries Survey to be carried out in the initial series, other surveys having been carried out on the Rivers Teign, Torridge, Dart and Erme. The object of the survey was to examine the distribution and relative abundance of salmonid fish in the river system, in order to assess the possibility, or desirability, of increasing salmon smolt production of the river by artificial propagation or other means. The survey was carried out from middle May to end of July in 1966 when further survey work was prevented by high water levels, and from the end of June to the end of September in 1967. It contains a brief introduction of general aspects of the catchment, chemistry, pollution, biology and fisheries in the river, methodology that looks at the selected transects and techniques for sampling, results and recommendations. The results goes through totals of all salmonid fish caught, adults, parrs and estimations of parr population individually for salmo salar and salmo trutta. Maps with survey sections and fish indices along with tables with size distributions and totals of salmonids found are attached.

O mote da presente pesquisa é perseguir os sentidos postos em circulação no Rio de Janeiro entre 1945 e 1955 sobre o existencialismo, em especial vinculado às ideias de Jean-Paul Sartre. Fortemente relacionado ao ambiente francês do pós-guerra, o existencialismo aqui é intencionado como produto que passa pelo crivo da carioquice, dialogando, por exemplo, com o carnaval e com as gestões de Vargas e Dutra. Das matérias jornalísticas coletadas em A Manhã e Última Hora, ambos periódicos cariocas importantes na época aqui focalizada, emergem três eixos principais: a encenação do existencialismo no campo político e religioso carioca; a circulação dessa filosofia entre os intelectuais brasileiros, bem como um levantamento das produções culturais conectadas ao existencialismo que circularam pela então capital nacional; e, por fim, a criação de certa moda existencialista no Rio e no país, atrelada a certos papéis de gênero, crimes, vícios, depravação. O que se afirma, afinal, é o quanto o existencialismo que circula pela cidade é menos um ismo de importação, noção presente em uma das matérias de jornal coletadas, do que uma produção também brasileira

树木年轮生态学是利用树木年轮来评价生态环境及其变化的学科,其基本依据是系列年轮宽度和结构特征的变化。一般情况下,半干旱草原的环境条件不适宜树木的生长,但在我国内蒙古锡林河流域的草原沙地上,存留着一片天然白扦林,它们被认为是第四纪早期的残遗植被。鉴于锡林河流域半干旱的环境条件已接近白扦的生存界限,此片残遗白扦林可认为是进行树木年轮生态学研究的理想材料。 本文应用树木年轮生态学的方法,结合木材解剖、气候资料、历史文献记录等,研究了这片残遗白扦林中白扦的生长与环境、年龄结构与环境干扰事件、白扦年轮宽度与羊草地上生物量的关系,以及全球变暖可能对该白扦林的影响等。主要结果归纳如下: 1)依据国际树木年轮库的标准,建立了65年的白扦标准年轮年表。年表的平均序列相关系数为0.47,信噪比为14.44,平均敏感度为0.18。白扦的年轮宽度年表与上年9月、当年2、5月份的降雨量之间存在显著的正相关关系。 2)通过对白扦年轮结构的观察确认,1966、1968、1972年存在高频率的窄年轮,这些年轮通常仅有两至三层晚材细胞,因此可以认为它是一类特殊的树木年轮一浅轮。  3)白扦的年轮分析结果显示,锡林河流域的小片白扦林可能形成于20世纪20年代末至30年代初期。白扦年表( XLPI)与大青山(HHT)油松、准格尔旗(JGB)油松以及白云敖包(BYAB)红杆云杉年表之间存在显著的正相关关系;尤其值得提出的是,在20世纪20年代,HHT、JGB和BYAB年表都同时出现明显的生长下降现象。  4)根据相关函数的分析,羊草的生长对当年5月份、7-8月份的降雨量较为敏感,与白扦的年轮宽度之间也存在两组显著的生长关系。基于这两种生长关系和白扦年轮宽度序列,本文重建了1955-1994年的羊草地上生物量动态。 5)当地气象资料显示,近40年来锡林河流域的年平均温度和各季节平均温度都呈增加的趋势,但只有夏季平均温度与白扦的年轮宽度之间存在显著的负相关关系。本文研究也发现白扦的生长与5月份的平均温度、平均最高温度以及5、6月份的极端最高温度之间存在着显著的负相关关系。 白扦标准年轮年表的统计特征表明,锡林河流域残遗白扦年轮序列包含丰富的环境信息,适合于树木年轮生态学的研究。白扦5月份开始生长,此时的降雨是最显著的生长限制因子,从而造成了白扦年轮年表与5月份降雨量之间的显著正相关关系。8-10月份,锡林河流域的降雨为全年降雨量的1/3,由于沙地土壤可以减少地面径流和有效防止土壤水分蒸发,所以此阶段内的降雨能存留在沙地内,以供笠年白扦生长发育的需要。因此,这种降雨分布和沙地基质的特征可能是白扦在年蒸发量为降雨量4-5倍的锡林河流域仍能正常生长的主要原因。 1966、1968和1972年浅轮的出现与前年和当年的特殊气候有关。气候资料的分析表明,这三年的上年生长季末至当年生长季都干旱少雨,并且生长季后期伴随着异常高温天气,这种干旱伴随高温的气候特点是造成白扦浅轮的主要因素。因此,白扦浅轮与亚北极区针叶树浅轮的发生机理是完全不同的,为迸一步研究浅轮的形成机制提供了新线索。 白扦年表与HHT、JGB和BYAB年表之间的年轮宽度变化的同步性显示,这些年表能间接地反映30年代以前造成白扦林较小年龄结构的环境干扰事件,降雨是华北半干旱区树木最突出的生长限制因子,在20世纪20年代,HHT、JGB和BYAB年表同时出现的生长下降,反映了该时期华北地区可能发生了大范围的旱灾,这一结论也为历史资料所证明。20年代白扦林的消失以及30年代后这片天然白扦林的重新出现表明了,20年代的旱灾可能是影响白扦年龄结构的主要干扰事件,它还有可能是造成白扦成片死亡的直接原因。 在锡林河流域,7-8月份是降雨最充沛的时期。相关分析表明,建群种羊草能充分利用这一水热配比最佳的时期快速生长,但白扦对当年7-8月份的降雨反应却不敏感,而与上年8-10月份的降雨量之间有显著的正相关关系。这些都证明白扦和羊草对半干旱草原环境具有不同的适应方式。羊草地上生物量与白扦年轮宽度之间的两组显著的关系可归结于两种季节降雨分配模式,它为利用白扦年轮宽度重建羊草的地上生物量的变化奠定了基础。羊草产量的重建不仅延长了锡林河流域草产量的记录,而且还开拓了用年轮宽度重建草产量的方法。 白扦年表与温度变量之间的相关分析进一步表明,不同季节温度的升高对白扦的生长产生不同的影响,尤其是夏季温度的变化,可以直接影响白扦的生长。白扦年表与5月份温度资料之间的相关分析还揭示,用月平均最高和最低温度来替代月平均温度更能说明温度变化对树木生长的影响。5、6月份是锡林河流域白扦形成层活动较旺盛的时期,因此,这期间极端高温严重影响白扦的生长。近40年来,随着大气温度的升高,白扦受到日益严重的干旱胁迫影响。如果大气变暖的趋势继续发展下去,最终将有可能导致这片残遗白扦林从锡林河流域消失

The Wadge Bank has been exploited regularly by Ceylon based trawlers since 1955 (Sivalingam & Medcof 1957). The bank is about 4,000 sq. miles in extent (Malpas 1926) and is located south of Cape Comorin within the Continental Shelf of India (Fig. 1). Carangids are taken in large numbers during the months of the south west monsoon (Sivalingam 1966). The quantity, in which the Carangids are captured as shown by the fishing records, is large enough to influence the total catch from the bank during these months (Fig. 2). Carangids are held in high esteem as excellent quality food fishes and accordingly constitute a commercially important group. This paper records the results of a detailed examination of the past fishing records in respect of this group, based on the analysis of the catch and fishing effort for the years 1957 to 1962. The distribution pattern of this group of fish in the Wadge Bank is discussed.

Continuous research on the freshwater fisheries industry in East Africa, in common with most other African countries, did not commence until the end of the Second World War in 1945. Before the war some work on the fishes and hydrobiology of the lakes of East Africa had been undertaken by a series of scientific expeditions, which were sent out from Europe, between the years 1896 and 1939. These expeditions usually lasted for only a few months, and the collected data were published by young graduates and undergraduates, including such people as Mr. L. C. Beadle, (lately Professor Beadle of Makerere), Mr. V. E. Fuchs (now Sir Vivian Fuchs) and Mr. E. B. Worthington of Gonville and Caius College,Cambridge. Later. Dr. Worthington became Scientific Secretary to the Scientific Council for Africa, Scientific Secretary to the East African High Commission, and played a very large part in the furtherance of fisheries research and management in East Africa.
