Resumen: En este artículo se analiza la Real Hacienda Imperial en Buenos Aires durante el siglo XVIII. En principio, se describen las fuentes, el sistema contable y la organización fiscal. A partir de lo anterior, se estudia la evolución de los ingresos fiscales discriminando los principales impuestos. Esto permite realizar un análisis de los ingresos y egresos de la Caja Real de Buenos Aires durante todo el período, en general y en relación con la evolución de la población. El resultado de ello demuestra que la hacienda real porteña no era deficitaria, por lo cual no dependía de transferencias de otras regiones para cubrir sus gastos. Al mismo tiempo se comprueba que los ingresos fiscales comenzaron a incrementarse a mediados del siglo XVIII, un cuarto de centuria antes de la creación del Virreinato del Río de la Plata.

Las relaciones de género en las comunidades negras están mediadas por el legado esclavista a la que fue sometida la población afro descendiente en las Américas, éstas se forjaron en la construcción histórica del ser negros. Aun la estructura patriarcal fue una potestad de los amos esclavistas, no del negro despojado de sí mismo, tanto el hombre como la mujer negro-negra esclavos fueron mercancías, su sexualidad y sus relaciones hicieron parte de la función de mercantil que le infringieron los amos, la maternidad fue un oficio y el hombre negro un reproductor de bienes. El derecho a Ser es el primer principio en la propuesta organizativa del Proceso de Comunidades Negras –PCN– como estrategia de dignificación del ser negros y de descolonización interna y externa desde el sujeto mismo hacia y desde la sociedad que le rodea.

A high-resolution record of sea-level change spanning the past 1000 years is derived from foraminiferal and chronological analyses of a 2m thick salt-marsh peat sequence at Chezzetcook, Nova Scotia, Canada. Former mean tide level positions are reconstructed with a precision of +/- 0.055 in using a transfer function derived from distributions of modern salt-marsh foraminifera. Our age model for the core section older than 300 years is based on 19 AMS C-14 ages and takes into account the individual probability distributions of calibrated radiocarbon ages. The past 300 years is dated by pollen and the isotopes Pb-206, Pb-207, Pb-210, Cs-137 and Am-241. Between AD 1000 and AD 1800, relative sea level rose at a mean rate of 17cm per century. Apparent pre-industrial rises of sea level dated at AD 1500-1550 and AD 1700-1800 cannot be clearly distinguished when radiocarbon age errors are taken into account. Furthermore, they may be an artefact of fluctuations in atmospheric C-14 production. In the 19th century sea level rose at a mean rate of 1.6mm/yr. Between AD 1900 and AD 1920, sea-level rise accelerated to the modern mean rate of 3.2mm/yr. This acceleration corresponds in time with global temperature rise and may therefore be associated with recent global warming. (c) 2005 Elsevier Ltd. All rights reserved.

Two new Standard pollen diagrams from the raised bog Ageröds mosse in central Scania are presented and discussed. They have been made giving extensive consideration to the NAP and spores also. The new diagrams comprise in the main only the Post-glacial and can easily be compared with the earlier published Standard diagram from the bog (T. NILSSON 1935). The development of the Post-glacial Vegetation in the surroundings is also discussed and compared with the conditions in the southernmost part of the province (Bjärsjöholmssjön, T. Nilsson 1961). One of the new diagrams has been prepared in connection with the study of a core brought up by means of a special borer in order to bring about C14 datings. The core was almost ömlong and had a diameter of 6 cm. It was divided into pieces of 2-6 cm, which were preserved. After the preparation of the pollen diagram, suitable samples were selected for C14 dating. In all 33 samples, comprising the whole Post-glacial inclusive of the youngest part of the Late-glacial, were C14-dated. With the aid of the C14 dates the growth conditions of the bog are discussed. After very slow Sedimentation of predominantly minerogenous deposits in the last part of the Late-glacial, and still slow Sedimentation of gyttjas in the oldest part of the Post-glacial, the rate of growth (primarily of the gyttja) distinctly increased in the first part of the Late Boreal. A temporary retardation of the growth of the sphagnum peat at the end of the Sub-boreal is probably entirely local. The average rate of growth of the really highly humified parts of the old sphagnum peat amounts to 42 mm per Century, that of the slightly humified young sphagnum peat 81 mm per Century or somewhat more. Based on the C14-determinations, the pollen zone boundaries have been given the following approximate dates: boundary Late-glacial/Post-glacial (DR/PB) 8300 B.C., boundary Pre-boreal/Boreal (PB/BO) 7900 B.C., boundary Early Boreal/Late Boreal (BO 1/2) 6800 B.C., boundary Boreal/Atlantic (BO/AT) 6200 B.C., boundary Early Atlantic/Late Atlantic (AT 1/2) 4600 B.C. (?), boundary Atlantic/Sub-boreal (AT/SB) 3300 B.C., boundary Early Sub-boreal/Late Sub-boreal (SB 1/2) 1700-1800 B.C., boundary Sub-boreal/Sub-atlantic (SB/ SA) 300 B.C., boundary Early Sub-atlantic/Late Sub-atlantic (SA 1/2) 650 A.D.

In the eighteenth century, the birth of scientific societies in Europe created a new framework for scientific cooperation. Through a new contextualist study of the contacts between the first scientific societies in Sweden and the most important science academy in Europe at the time, l Académie des Sciences in Paris, this dissertation aims to shed light on the role taken by the Swedish learned men in the new networks. It seeks to show that the academy model was related to a new idea of specialisation in science. In the course of the eighteenth century, it is argued, the study of the northern phenomena and regions offered the Swedes an important field of speciality with regard to their foreign colleagues. Although historical studies have often underlined the economic, practical undertone of eighteenth-century Swedish science, participation in fashionable scientific pursuits had also become an important scene for representation. However, the views prevailing in Europe tied civilisation and learning closely to the sunnier, southern climates, which had lead to the difficulty of portraying Sweden as a learned country. The image of the scientific North, as well as the Swedish strategies to polish the image of the North as a place for science, are analysed as seen from France. While sixteenth-century historians had preferred to put down the effects of the cold and claim a similarity of northern conditions to the others, the scientific exchange between Swedish and French researchers shows a new tendency to underline the difference of the North and its harsh climate. An explanation is sought by analysing how information about northern phenomena was used in France. In the European academies, new empirical methods had lead to a need for direct observations on different phenomena and circumstances. Rather than curiosities or objects for exoticism, the eighteenth-century depictions of the northern periphery tell about an emerging interest in the most extreme, and often most telling, examples of the workings of the invariable laws of nature. Whereas the idea of accumulating knowledge through cooperation was most manifest in joint astronomical projects, the idea of gathering and comparing data from differing places of observation appears also in other fields, from experimental philosophy to natural studies or medicine. The effects of these developments are studied and explained in connection to the Montesquieuan climate theories and the emerging pre-romantic ideas of man and society.
