É uma tradução da Corographia brasilica... de Ayres de Cazal, acrescida de observações pessoais que o autor colheu durante sua viagem, conforme afirma no prefácio da própria obra. É um livro muito útil para estudo da sociedade pernambucana antes de 1817. A Corographia brasílica..., de Cazal, reveste-se de importância histórica por ter publicado, pela primeira vez, a carta de Pero Vaz de Caminha, segundo informa Borba de Moraes.

Através de narrativas sobre as práticas cotidianas de quatro professoras (três brasileiras e uma francesa), acompanhadas de narrativas desenvolvidas entorno de um conjunto de imagens de alunos, esta pesquisa busca pensar como professores e alunos produzem os currículos nos seus cotidianos escolares. Através dos diferentes usos dos materiais disponíveis, dos questionamentos, das histórias de vida e das inúmeras experiências que constituem as subjetividades, os praticantes das escolas tecem, em redes, os seus conhecimentos e suas significações para a vida. Problematizando esta temática, com a professora de artes, Cristiane Costa, busco desenvolver uma discussão metodológica sobre os estudos dos cotidianos, me propondo compreender algumas possibilidades das táticas cotidianas de aprenderensinar. Com uma professora de matemática, Luciana Getirana, acompanhada da narrativa de uma aluna, Maria Nunes, analiso as relações entre conhecimentos científicos e conhecimentos cotidianos. Em seguida, com a professora de língua portuguesa, Cristiane Souza, discuto as demandas de professores por uma fórmula, uma receita de bolo, que contenha algumas soluções para os problemas da educação. Com a professora de história e geografia, Laure Cambos, busco pensar o professor no atravessamento de fronteiras entre culturas e conhecimentos. Neste sentido, elegi duas práticas de mediação cultural presentes no cotidiano desta professora: a primeira é o uso de imagens como prática de aprenderensinar, e a segunda consiste nas atividades de saídas da escola (aulas caminhadas). Por último, reúno fotografias de alunos para desenvolver duas temáticas que entrelaçam os capítulos anteriores: o dentrofora das escolas e as experimentações do mundo. A partir de narrativas sobre estas imagens, procuro pensar os cotidianos dos alunos nas práticas de aprenderensinar. Compreender estes currículos em redes possibilita problematizar as noções que não reconhecem a fragilidade das fronteiras, por perceberem os cotidianos através de relações dicotômicas. Estas fronteiras são habitadas pelos professores, produtores de possibilidades de mediações entre diferentes culturas e conhecimentos. Como práticas de atravessamento de fronteiras, as práticas de aprenderensinar buscam alternativas para a dicotomia que separa o dentro e o fora da escola, os conhecimentos cotidianos e os conhecimentos científicos, bem como os currículos prescritos e os currículos vividos. A pesquisa tem apoio teórico em autores como Nilda Alves, Michel de Certeau, Henri Lefebvre, Boaventura Santos, Nèstor Canclini entre outros.

© 2014 IEEE. This exploratory study addresses a gap in management literature by addressing the role of location in the continuously expanding field of open innovation research. In this context, we analyze potential negative effects of absolute geography and relative proximity on open innovation practices in high-tech small and medium-sized enterprises (SMEs) in the United Kingdom. Drawing upon cluster theory and business ecosystem literature, the analysis from three SME case studies in the East of England suggests that presumed 'favorable' location variables, such as close relative proximity between partners and the presence of economic clusters, can have certain negative effects on open innovation practices.

小麦(Triticum aestivum L.)是世界上种植面积最大,总产量最高,食物加工种类最丰富的粮食作物,占世界人口35 %-40 %的人们以此为主要食物。因此小麦产量的高低和品质的优劣直接影响人们对食物需求的安全和满意程度,也影响着人类的营养平衡以及面粉和食品加工业的发展。随着生活水平的提高,人们对于小麦的品质越来越重视。培育优质专用小麦新品种,制定优质专用小麦品种品质生态区划,从而在不同程度上实现小麦的区域化种植和产业化经营具有重要的意义。 影响小麦品质的因素主要是遗传因素和环境因素,其中环境因素又包括各种自然生态因素和人为因素。研究表明,小麦品质的环境间的差异大于品种间的差异,气候条件是影响小麦品质的最重要的因子,小麦品质的地域间的差异反映出了小麦的品质区域分布规律。为了满足市场对不同品质小麦的需求,对小麦进行区域化研究具有重要的理论和现实意义。本研究结合四川的地理、气候特点,研究不同品质类型与生态环境的关系,为在复杂的生态环境内进行品质区划提供依据。 本研究首先根据四川省小麦种植区域的生态特点,在四川省多个典型生态区:川南丘陵的荣县、川西南高原的西昌、川西平原的双流布点种植,采用的小麦试验材料为不同品质类型:中筋小麦川育12、川育14、川育16由本所提供;弱筋小麦川麦32和强筋小麦川麦36由四川省农科院作物所提供。通过研究品质性状与品种及各个生态因子包括地点、土壤土质差异等的关系,明确不同生态环境中适宜种植的小麦品种类型,强筋小麦、中筋小麦更适合于在荣县、双流地区种植,弱筋小麦更适合于在西昌地区种植,为品种品质区划奠定基础。 其次,选择了本课题组育成的稳定中间品系,对其品质性状SDS沉降值进行了多年测定。分析了品质性状SDS沉降值与多种气候因子的相关性,结果表明SDS沉降值与日均温、日照时数成正相关,与降水量成负相关,为品质育种提供了理论依据。 此外,以中筋小麦新品种小麦川育14为材料,应用三元二次正交旋转回归模型设计试验,研究主要栽培因子播期、密度和施肥量对产量的影响,并建立函数模型。经计算机模拟寻优,筛选出了高产高效栽培组合措施,并确定了置信域。结合四川省不同的地理情况,在平原和丘陵地区分别进行实验,并各自建立了高产高效栽培组合措施,为川育14品种的推广提供了理论指导。 Wheat is one of the most important crops in the world. About 35%-40% people all over the world, take the wheat as their most important food. So the quality, as well as the quantity of the wheat makes a direct effect on people’s demands of food and their satisfaction. It also effects on human’s healthy, and the development of the Food processing industry. With the development of the living standard, people pay more attention to the quality of wheat. So, we set a special ecology zoning for wheat. It is significant to carry out planting the wheat in special zoning in varying degrees. The main factors affecting wheat quality are heredity and environment including many ecological factors and the factors in cultivation. As to the quality,the difference between ecology and cultivation is more important than the difference between special wheat. In so many factors, climate is the most important one. From the difference in quality between different zones,we can conclude the rule of distribution abort quality of wheat. Finding out the intersection of numerous wheat not only can meet the demand of food production,but also has important signification in theory and realism。In our research, according to the complex geography in Sichuan province, we study the relationship between numerous kinds of quality characters in wheat and the ecology. So, we can set a foundation for more research. In this research, firstly, we plant wheat in some typical ecological regions of SICHUAN province: RONGXIAN(south of SC)、XICHANG(south of SC), SHUANGLIU(west of SC). The materials of the experiments: ChuanYu12, ChuanYu14, ChuanYu16(from our institute), Chuanmai32, Chuanmai36 (from the Chinese academy of agriculture sciences of Sichuan. Through the research on the relationship between the quality of wheat and those ecology factors, we can make a definition that which area is perfect matched with which kind of wheat. And it can satisfy the demand of people. Secondly, select many sorts of wheat from our research group. All of them are selected and bred more than 3 years(2003-2005). And we make every-year determination as well. We’ve gotten SDS value from those 9, and various data on factors of climate. We also got to know the relation ship between those numbers. Thirdly, use Chuanyu14 as material, the mathematical model of the relation between the production of wheat and main agricultural measures such as date, density and fertilizer. The model was established by association of three elements two return, rotate and regression. We set a suitable model and get a suitable method which can make high harvest. Based on various kinds of geographical regions in Sichuan province, we set different models which can be used in plain and hill. So, we can plant Chuan Yu 14 in Sichuan province under the result in research.
