环境变迁在中国文明形成中的作用

The formation of civilization, one of great marks in the history of human's society development, has been remained one of the hottest topics in the world. Many theories have been put ford to explain its causes and mechanisms. Although more attentions have been paid to its development, the role of environmental change should not be ignored. In this paper, the level of ancient farming productivity was analyzed, the mechanisms and the process of Chinese ancient civilization formation was explored, and some causes why Chinese ancient civilization shows many different features from other 5 ancient civilizations of the world was analyzed. The main results and conclusions are presented as followed. 1. Compared with the productivity level of other five ancient civilizations, the productivity of ancient China characterized by a feature of extensive not intensive cultivation was lower than that of other five ancient civilizations whose agriculture were based on irrigation. 2. The 5 5000 a B.P. cold event may have facilitated the formation of Egypt and Mesopotamian ancient civilizations and also have had an influence on the development of Neolithic culture in China. 3. The 4 000 a B.P. cold event, which may be the coldest period since the Younger Dryas cold event and signifies the changes from the early Holocene Climate Optimum to late Holocene in many regions of the world, resulted in the great migration of the Indo-European peoples from north Europe to other part of the World and the collapses of ancient civilizations in Egypt, Indus and the Mesopotamian and the collapse of five Neolithic cultures around central China. More important than that is the emergence of Chinese civilization during the same period. Many theories have been put ford to explain why it was in Zhongyuan area not other places whose Neolithic cultures seem more advanced that gave rise to civilization. For now no theory could explain it satisfiedly. Archaeological evidence clearly demonstrate that war was prevailed the whole China especially during the late Longshan culture period, so it seemed war has played a very important role in the emergence of China ancient civilization. Carneiro sees two conditions as essential to the formation of complex societies in concert with warfare, i.e. population growth and environmental circumscription. It was generally through that China couldn't evolved into the environmental circumscription and population pressure because China has extensive areas to live, but that depends on situations. The environmental circumscription area was formed due to the 4000a B.P. cold event and companied flooding disasters, while the population pressure is formed due to three factors; 1) population grow rapidly because of the suitable environment provided by the Holocene Optimum and thus laid its foundations for the ancient human population; 2) population pressure is also related to the primitive agricultural level characterized by extensive not intensive cultivation; 3) population pressure was mainly related to the great migrations of people to the same areas; 4) population pressure was also related to productivity decrease due to the 4 000a B.P. cold event. 4. When population pressure is formed, war is the most possible way to solve the intensions between population and the limited cultivated land and then resulted in the formation of civilization. In this way the climate change during the 4 000a B.P. cold event may have facilitated the emergence of Chinese ancient civilization. Their detailed relations could also be further understood in this way: The first birth places of China ancient civilization could be in Changjiang areas or (and) Daihai area, Shandong province rather than in central China and the emergence time of ancient civilization formed in central China should be delayed if the 4 000a B.P. cold event and companied flooding disasters didn't occurred.

中国南方热带地区田洋玛珥湖24万年以来的气候变化及湖泊演变

A continuous long (224m) and high-resolution core TY2 was recovered from paleo-maar-lake Tianyang, tropical South China. Based on the diatom records of the upper 130-m core, this paper focuses on exploring climate change and the lake evolution history in tropical South China during the past 240ka. The most typical and unique characteristics of the diatom assemblages is that, Aulacoseira granulata was dominant or absolutely dominant species (80-90%) during most parts of the 130-m core, while Cyclotella stelligera var. tenuis and Fragilaria construens var. venter were subdominant species in only limited parts of the lower and upper core, respectively. Time scale is always the biggest problem for the study of TY2 core, so although diatom is seldom used for establishing time scale, here we attempt this by correlating the diatom-reconstructed temperature sequence with the time scale of ODP core 806B from Equatorial Western Pacific. Verified by the few most reliable ages from TY2 core and the parallel core TYl, a rather reasonable and reliable time scale was established. 01S 7/6 falls at the depth of 100m (ca. 194kaBP), OIS 6/5 at 75m (ca. 132kaBP), OIS 5/4 at 46m (ca. 75kaBP), OIS 4-3 at 35m (ca. 60kaBP). Qualitative and quantitative environmental reconstructions are made on the basis of diatom assemblage ecotype and EDDI dataset. Correlation of diatom-reconstructed temperature and moisture changes of Core TY2 with pollen-reconstructed temperature and rainfall sequence of Core TYl proves that the results are quite consistent in most periods. Thus the reconstruction results from diatom are quite reliable, and probably have a much higher resolution than pollen results. Combined with lithological and magnetic susceptibility variations, the diatom analysis reveals that, the general climate in tropical South China during the past 240ka was warm and wet. On the time scale of glacial-interglacial, warm and wet, cool and dry are not always synchronous. It was relatively warm-wet during the penultimate interglacial, cool-dry during the penultimate glacial, warm-dry during the last interglacial, and cooler-drier during the last glacial. In contrast, on the time scale of subglacial-subinterglacial scales, warm and dry, cool and wet corresponds very obviously, showing very clear 21-23 ka precession cycle. Analysis also shows that, the water of Tianyang paleo-maar-lake was generally warm, turbulent, turbid, meso-trophic, slightly alkaline, low conductivity and fresh during the past 240 kaBP, with small variations in some parts. Tianyang paleolake experienced shallow to semi-deep lake in OIS7d, open shallow lake in OIS7c-OIS5b, shallow coastal lake in OIS5a-OIS4c, swamp in OIS4b, and then completely dried up in OIS3c. The lake evolution was mainly controlled by temperature and precipitation changes in tropical China. While temperature and precipitation changes were probably controlled by the migrations of monsoon rainband and the evaporation rate, which was in turn controlled by the evolution of East Asian monsoon. Therefore, when the summer monsoon was strongest the climate was warm-dry, when stronger the climate was warm-wet; when the winter monsoon was strongest the climate was cool-dry, stronger cool-wet. This mechanism caused the warm-dry sub interglacial and cool-wet subglacial climate in the tropical South China.

Economic restructuring in New Zealand: A classical account

New Zealand's recent experiment with radical neoliberalism is well rehearsed in international policy circles. Yet, given the economic restructuring premise for the reforms, there has been little assessment of their structural impact. In this paper I take up this challenge, utilising [Shaikh, A., Tonak, E. Measuring the wealth of nations: the political economy of national accounts. Cambridge: Cambridge University Press; 1994] methodology for deriving classical value categories from official national accounts data but extending this to the industry level. This approach allows changes to the production and appropriation of surplus value in different industries during the period to be identified, underpinning a Marxian interpretation of restructuring. Beyond the methodology, the research makes four contributions. First, conventional analysis is found limited by its concentration on changes to the distribution of value rather than its creation. Second, land rents are significant. Third, the role of financial capital is found more complex than traditionally argued. Finally, the approach provides a firm grounding for the unfashionable concept of class fraction.

Cuestiones de escala en el ámbito de la “Huella Hídrica”.

La aplicación de la “Huella Hídrica” a la realidad española debe hacerse desde la consciencia de que hasta hace relativamente poco, el pensamiento científico dominante era el reduccionismo, cuyo enfoque considera que basta un conocimiento detallado de cada uno de los componentes de un sistema y de sus leyes fundamentales, para entenderlo globalmente. Y es que, el interés por este indicador surge de la importancia que cobran conceptos como “escasez” y “contaminación” del agua, como consecuencia directa e indirecta de la actividad humana sobre los sistemas hídricos, tanto en España como en los países de América Latina; con el fin de mejorar la gestión –desde la oferta y la demanda- de los recursos hídricos del planeta y reducir las desigualdades territoriales. De este modo, en el presente estudio se realiza una estimación de la “Huella Hídrica” de España y América Latina, así como de a la Red de Parques Nacionales Españoles, tanto a nivel económico como ambiental, describiendo los recursos hídricos utilizados, necesarios para satisfacer la demanda de bienes y servicios consumidos, en los prolegómenos del siglo XXI.

Nationalism, Ethnicity and Self-Determination: A Paradigm Shift?

An ongoing paradigm shift is giving birth to a more multidimensional understanding of the relationship between nationalism, sovereignty, self determination and democratic governance. A common element across the various versions of the new paradigm is the dispersal of democratic governance across multiple and overlapping jurisdictions. Governmental processes are no longer seen as discrete, centralised and homogenous as in the old nation-state model, but as asymmetrical, multilayered and multicultural, with devolution into multiple jurisdictions. These changes have hardly affected the two main conceptual frameworks that dominate the study of nationalism, Modernism and Ethnosymbolism. As a result, they risk becoming irrelevant to the new forms of national self determination, asymmetrical governance and shared sovereignty. Modernism and Ethnosymbolism insist that nationalism seeks to equate the nation with a sovereign state, while in reality the overwhelming majority of nations are stateless and unable to build nation states, as they often inhabit territories shared with other nations. The paradigm shift occurs precisely with the realisation that nation state sovereignty is no longer a feasible solution to the demands of stateless nations. Ethnosymbolism is in a much better position to adapt to the paradigm shift provided it abandons the claim that the nation state is the best shell for the nation.

James Anderson's Political Economy--His Influence on Smith and Malthus

James Anderson's powerful critique of Adam Smith's position on the corn export bounty was published in 1777. It focuse d on Smith's proposition that the bounty could not lead to increased corn production because it could not increase corn's real price. Smit h's response to the critique is traced in later editions of Wealth of Nations. While Anderson's critique of Smith influenced Thomas Malthu s's writings from 1803 onwards, his theory of differential rent did n ot influence Malthus at this stage. An examination of the evolution o f Malthus's ideas on rent between 1803 and 1815, however, indicates t hat Malthus knew and used Anderson's work on rent.

A educação em ciências no ensino básico em ambientes integrados de formação

A educação integral ao longo da vida de todos os indivíduos, em contextos formais, não formais e informais, com vista ao desenvolvimento inteligente, sustentável e inclusivo das nações é, actualmente, uma recomendação unânime de entidades e organizações a nível internacional (ex. UNESCO, UNICEF, NU, OCDE, OEI, UE). Neste âmbito, destaca-se o papel fulcral da literacia científica dos indivíduos, como motor do crescimento, produtividade e competitividade dos países e como um dos pilares basilares para o exercício de uma cidadania consciente na vida política, social e cultural. Para alcançar tais propósitos é necessário uma forte aposta numa educação de qualidade desde os primeiros anos de vida dos indivíduos. Para tal, é fundamental: (re)pensar perspectivas de educação, de ensino e de aprendizagem; dar reposta às amplamente reconhecidas necessidades de formação inicial e continuada de professores; e assegurar a existência de infraestruturas e recursos de suporte à concretização de tais anseios. O presente estudo pretende ser um contributo para a operacionalização de tais intenções, no campo particular da educação em ciências ao nível do ensino básico, tendo subjacente uma perspectiva de abordagem integrada e integradora da educação em ciências. O percurso de investigação, de natureza qualitativa, foi desenvolvido incidindo em dois focos fundamentais: (i) o desenvolvimento de infra-estruturas e recursos de suporte à educação em ciências e (ii) o desenvolvimento de um programa de formação continuada para professores do 1º CEB de educação em ciências na perspectiva considerada. Assim uma das grandes finalidades do estudo foi desenvolver (conceber, planificar, implementar e validar) um Centro Integrado de Educação em Ciências (CIEC) como parte integrante de uma escola do 1ºCEB. Partindo de orientações da literatura, da proficiência da equipa multidisciplinar e dos contributos de avaliadores externos procedeu-se ao desenvolvimento do conceito CIEC e respectivo espaço físico de suporte: espaço de educação formal - laboratório de ciências para o 1ºCEB; espaço de educação não formal – Centro de Ciência do CIEC.A segunda grande finalidade do estudo, foi o desenvolvimento (concepção, planificação, implementação e avaliação) de um programa de formação continuada que habilitasse os professores do 1ºCEB a desenvolverem actividades integradas de educação em ciências (AIEC). Tendo por base as orientações da literatura, bem como a caracterização das práticas, necessidades e expectativas dos professores-formandos, concebeu-se, planificou-se e implementou-se o programa de formação. A avaliação do programa efectuou-se tendo por base a análise dos dados recolhidos através de fontes distintas, e o seu cruzamento com recurso a métodos, técnicas e instrumentos diversificados. Assumindo-se como um contributo para a melhoria da educação em ciências nos primeiros anos de escolaridade, o presente estudo apresenta como resultados orientações para: o desenvolvimento de laboratórios em escolas do 1ºCEB; o desenvolvimento de centros de ciência, e ou espaços de educação não formal similares, e respectivo funcionamento; a implementação de actividades integradas da educação em ciências; o desenvolvimento de programas de formação continuada de professores; o processo de auto e hetero avaliação de práticas de professores no que respeita ao ensino das ciências em contextos formal e não formal.

Neochelys sp. (Chelonii, Erymnochelyinae), from Silveirinha, early Eocene, Portugal

Constituted of isolated fragments with a smooth decoration, the turtle material from Silveirinha is examined in order to define its sure belonging to Neochelys, by comparison with other smooth turtles which may be present during the Palaeogene of Europe (freshwater Testudinidae, Erymnochelyinae, Bothremydidae). The elements are compared with the already known Neochelys species of the Eocene European localities. Questions are made about the possible geographical migrations of turtles between South and North during the early Eocene of western Europe. The phyletic relationships cannot be established but the species, seeming new and one of the more primitive as a whole (after the preserved elements), is the older from the Iberian Peninsula.

A regulação da atividade espacial

The technological evolution of the past fifty years has provided Humanity the contact with the last frontier of knowledge: space. An unknown world, explored by a small group of nations, which has become crucial to understanding who we are and where we come from. Space assets in recent years have opened the way to a digital society, shaped by the rapid exchange of information, whose means are mostly in space. A place of fascination and curiosity, restricted to a few people in these decades, which may soon be changing. This essay addresses some legal issues concerning the private exploration of space. Liability on space tourism is the core of this investigation, focusing on the comprehension of the international legal framework and its connection with the states national law. In particular, the study of the main international treaties, the U.S. legal system of space law and the developments in Europe are the fundamental tools of the current analysis, not forgetting the point of view of a possible international harmonization. Besides the needed theoretical context on the evolution of space law and a brief approach of the technical matters of the current aerospace engineering, the goal is to examine the characteristics of international space law and its relation with the new private actors, responsible for providing suborbital flights, operating in a near future. Within these circumstances, given the economic potential of the growing private space industry, it is essential to discuss the legal aspects of a spatial regulation. Being liability, undoubtedly, the emerging issue in the legal debate on this topic, it is important to safeguard the interests of the operators, States and, above all, future space tourists.

Modern piracy

A definição de pirataria ou a desmistificação da sua origem, no tempo e espaço, revela maiores dificuldades do que atualmente. Com este trabalho propusemo-nos a estudar como é que a pirataria era perpetrada e entendida no passado, bem como no presente. Também nos propomos a identificar limitações legais e as medidas operativas no combate à pirataria, como por exemplo: limites conceptuais, lacunas, estratégias, entre outros. Por outro lado, atendemos as soluções encontradas no combate à pirataria sem deixar de observar fraqueza da lei e conflitos entre jurisdições. Por fim, o curso da história dá-nos a seguinte percepção: a pirataria era tida como crime se fosse contra os interesses das nações. O desinteresse dos Estados para reprimir a pirataria possibilitou o seu aumento, proliferação, domínio e sofisticação em certas regiões do Mundo. O presente trabalho tem como objetivo trazer para o centro da discussão os direitos humanos numa perspetiva tripla: proibição da pirataria, supressão e raízes, aliando o estudo de possíveis respostas a dar a esta epidemia.

Droits de propriété intellectuelle et protection des plantes: approches, limites et perspectives

Le droit de la propriété intellectuelle présente, depuis quelques années, un intérêt particulier à l'évolution de la recherche sur les plantes. Ceci s'est traduit, au plan international, par l'adoption de plusieurs instruments visant à assurer une meilleure protection des investissements consentis dans ce domaine. Il s'agit notamment de la Convention de l'UPOV, qui s'inscrit dans une logique de protection par la voie sui generis avec la possibilité de délivrance de certificat d'obtention végétale aux sélectionneurs; de l'Accord ADPIC, qui, en plus de recommander un système sui generis efficace, ouvre l'option de protection par brevet ou en définitive par le cumul des deux systèmes; de la Convention sur la Diversité Biologique (CDB) et du Traité de la FAO portant sur les ressources phytogénétiques pour l'alimentation et l'agriculture, qui, favorables aux deux précédentes formes de protection, demandent que soient prises en compte des considérations relatives aux droits souverains des pays sur leurs ressources végétales, au partage des bénéfices, etc. Au plan régional, on distingue, entre autres, l'initiative de l'Afrique, visant à assurer la protection des plantes suivant une logique partagée entre l'alignement sur les normes internationales existantes (Accord de Bangui) ou l'institution d'une autre législation originale qui reflète les réalités et préoccupations du continent (Loi modèle). Il apparaît donc qu'il existe plusieurs instruments pour cerner la même réalité. Ceci est forcément la source de quelques difficultés qui sont d'ordre conceptuel, socioéconomique, environnemental et juridique. Pour les pallier, il est important que certaines conditions soient satisfaites afin d'harmoniser les points de vue entre les différents acteurs concernés par la question et d'assurer une appropriation conséquente des instruments adoptés.
