Community‐based forestry management is emerging as an important component of forest policies in the developing world. Using the Philippines as a case‐study, this article critically examines the way in which community‐based forestry is constructed and understood among government policy makers. The author suggests that the new policy discourse of community‐based forestry policy in the Philippines is still shaped by efforts to maintain centralized control over forest management and a political economy orientated towards commercial timber production using the principles of ‘scientific management’. While timber production and the technical aspects of forest management are emphasized, social and environmental considerations remain neglected.  相似文献

The authors attempt to solve the enigma about the possible aphasia of the Byzantine Emperor Manuel II Palaeologus (1391–1425) in the 3-year period between his first and his second and fatal stroke. The texts of historians and chroniclers reveal that Manuel remained semi-paralyzed at bed and his motor disability alienated him from the state affairs and condemned him to isolation from all embassies and contact with others, except his family. Only the funeral oration of the Bishop Bessarion raises the suspicion of a speechless emperor. All testimonies referring to this infirmity are examined.  相似文献

A comic-book series by French artist Jacques Ferrandez serves as a case study of how Pied-noir memories of Algeria are given expression in popular culture. Ferrandez recreated French Algeria as a virtual place of memory in his five-volume Carnets d'Orient , by borrowing images from colonial postcards and orientalist paintings, as well as stories from sources including his own family history and French travel writings about the 'Orient'. Although he provides a useful critical perspective on the colonial period, he is limited in this effort by his identification with the Pied-noir community, and his desire to memorialise French Algeria.  相似文献

This experiment assessed whether consolidation of cremated remains facilitated cross‐sectioning and grinding, which often are required for microstructural analyses such as the histomorphometric estimation of age and the examination of pathological lesions. Green, bovine femoral diaphyses were cremated at three temperature ranges (346–357°C; 610–755°C; 684–838°C) in an electric furnace and then consolidated with Acryloid B‐72 or Butvar B‐98 using simple brushing and immersion techniques. After consolidation was complete, bone pieces were cross‐sectioned and ground to a thickness of 100–120 μm. Results indicate that specimens treated with Acryloid B‐72 are harder and stronger than Butvar treated and untreated control specimens. Acryloid B‐72 is, therefore, recommended for the consolidation of cremated remains in preparation for microstructural analysis. Copyright © 2004 John Wiley & Sons, Ltd.  相似文献

The ‘pollen washes’ technique, based on the analysis of the pollen embedded in the porous surface of archaeological artefacts, is developed for investigating past plant usage and consumption and to characterize the functionality of artefacts related to plant processing, gathering and storage. The research presented results in relevant methodological improvements of this technique, which has never previously been applied on materials from European contexts. The improvements allow: (1) faster analysis of a broad series of artefacts or those with large use‐surface areas likely to retain more pollen; and (2) a more thorough, deeper and precise cleaning method, allowing the study of smoother artefacts. Finally, the recovery of Trifolium‐group pollen from a macro‐lithic tool from Xicotó rock shelter (Montsec ranges, Spain) demonstrates that the pollen washes technique can reveal new insights into both the use and consumption of wild and domestic plants by prehistoric societies, and the functionality of archaeological objects whose interpretation is still problematic.  相似文献

Urban heat islands (UHIs) and the vegetation that mitigates them vary across space and time, but little research has investigated this coupled natural–human system using both spatial and temporal analyses. Focusing on semiarid, water‐scarce Tucson, Arizona, we examined whether outdoor water use by residents of single‐family homes (a practice that uses close to half of residential water supplies) contributes to urban “greenness” and the mitigation of UHI effects. Specifically, we investigated how different types of residential development mediate vegetation–water use–temperature interactions. Our data sets include Landsat‐derived normalized difference vegetation index (NDVI) and surface temperatures, parcel‐level zoning and assessor data, and residential water use records at the quarter section level (0.63 km2). We analyzed these data at multiple spatial and temporal scales. Spatial analysis results demonstrate that cooling from vegetative evapotranspiration is mediated by development factors as well as by topography and wind patterns. Findings also suggest that outdoor water use aside from irrigation, particularly the use of swimming pools, promotes cooling without elevating the NDVI. Temporal analysis reveal that most residential areas maintained or increased greenness despite declining 1995–2008 water use due most likely to long‐term regional climate cycles. Only high‐density developments with little undeveloped ground cover and few natural drainage channels exhibit a strong relationship between household water use and NDVI trends. These results suggest that the preservation of natural drainage channels and limitation of impervious surfaces, as well as the siting of development in naturally cooled microclimates, may be sustainable strategies for UHI mitigation in water‐scarce regions. Análisis multi‐escalar de los impactos de riego en residencias unifamiliares: la correlación entre la vegetación, el uso del agua y la temperatura superficial en un área urbana semiárida Las islas de calor urbano (urban heat islands‐UHIs) y las áreas con vegetación que ayudan a mitigarlas varían en su distribución especial y temporal. Sin embargo, existe relativamente poca investigación dedicada al análisis espacio‐temporal de este sistema acoplado humano‐ambiental urbano. El artículo examina la medida en la cual el uso de agua al aire libre por parte de residentes de viviendas unifamiliares (practica que consume mas de la mitad de los recursos hídricos) contribuye al “verdor” de áreas urbanas y a la mitigación de los efectos de las UHs. El área de estudio es Tucson, Arizona, una ciudad ubicada en un ambiente semiárido que sufre de escasez hídrica. En términos más concretos, los autores investigan cómo los diferentes tipos de desarrollos urbanos residenciales sirven de mediadores en las interacciones entre la vegetación, la temperatura y el uso del agua. Como datos se utilizaron índices de vegetación (Normalized difference vegetation index‐NDVI) y temperaturas superficiales derivados de imágenes Landsat. Así mismo se usaron datos catastrales a nivel de parcela de zonificación, y registros de uso residencial de agua a nivel de cuarto de sección (quarter‐section) (0,63 km2). Los datos fueron analizados a múltiples escalas espaciales y temporales. Los resultados de análisis espacial demuestran que el enfriamiento de la evapotranspiración vegetal está influenciado por los factores de desarrollo urbano residencial así como por los patrones topográficos y climáticos (viento). Los resultados también sugieren que los usos de agua al aire libre, aparte de riego, en particular el uso de las piscinas (o albercas), promueven el enfriamiento sin elevar el valor del NDVI. El análisis temporal revela que la mayoría de zonas residenciales mantuvieron o aumentaron el ‘verdor’ a pesar de la disminución del uso del agua entre 1995 y 2008, debido probablemente a los ciclos climáticos regionales de largo plazo. Únicamente las zonas urbanas de alta densidad con escasas áreas verdes y pocos canales naturales de drenaje muestran una fuerte relación entre el uso del agua residencial y las tendencias del NDVI. Estos resultados sugieren que la preservación de los canales de drenaje natural y la reducción de superficies impermeables, así como el emplazamiento del desarrollo urbano en áreas con microclimas naturalmente más fríos, pueden ser estrategias sostenibles para la mitigación de UHIs en regiones con escasez de agua. 城市热岛与可缓解其效应的植被均随时间和空间变化,但鲜有研究从时空分析视角关注这一自然‐人文耦合系统。本文聚焦于半干旱、缺水的亚利桑那州图森市,主要调查独户家庭户外用水(其用水量大约是住宅供应水量的一半)是否对城市“绿化”和缓解城市热岛效应作出贡献。特别地,我们调查不同类型住宅开发是如何调节植物‐用水‐温度间的相互作用。数据集包括从美国陆地资源卫星获得的归一化植被指数(NDVI)和地表温度,地块区划和评估数据, 约160英亩(0.63 km2)用地面积的住户用水记录。我们从时空多尺度视角对这些数据进行了分析。 空间分析结果表明,植被蒸散作用导致的降温不仅受开发因素也受地形和风模式的调节。同时也发现:包括灌溉的户外用水,尤其是泳池用水,在促进地表降温时并未促使归一化植被指数(NDVI)提高。时间分析揭示,大多数居住区即使在1995–2008用水减少的情况下仍保持和增加“绿化”,最可能归因于长期的区域气候循环。只是在植被覆盖和自然排水系统均很少的高密度开发地区,家庭用水与NDVI趋势上显示出强相关性。这些结果昭示保留自然排水系统和限制不透水地表,以及在具有自然降温作用的微气候上选址发展区,或许是缺水地区缓解热岛效应的可持续策略。  相似文献

Indigenous movements face what Stuart Kirsch has called the ‘risks of counterglobalization’, which can distort their objectives into an all‐or‐nothing position with respect to development. In this contribution, I explore a case from the Philippines, where a movement originally conceived in terms of indigenous rights grew to include a more diverse mix of constituents and claims. This trajectory has made the movement vulnerable to charges of inauthenticity, particularly since the corporation it opposes has sponsored a parallel indigenous group and fashioned itself as the noble custodian of a threatened marine ecosystem. Nevertheless, the movement's constituents do not evaluate their activities exclusively in terms of its formal objectives or identity politics. For them, organized protest is entangled with the ‘serious games’ of everyday life, including, for example, local elections, struggles to achieve upward social mobility and efforts to redefine ethnic identity. As a result, some constituents see their involvement primarily as a claim to socioeconomic parity and others as a pursuit of the exceptional rights that indigeneity confers. Without attention to such local‐level variation, we risk obscuring some of the most important motives and outcomes of indigenous movements — and, as a result, we may overlook the alternative visions of socio‐environmental justice that emerge from their day‐to‐day struggles for livelihood, dignity and empowerment.  相似文献

This paper examines the politics of dress in twentieth‐century Philippines, exploring the imbrication of dress, politics and gender. It argues that there was an inherent tension between Western Dress/Filipino Dress in the period as the contrast between these two types of dress came to represent opposing political and gendered identities. The visual categories of Western Dress/Filipino Dress did not always 'naturally' correspond to not nationalist/nationalist, powerful/disempowered, modern/traditional, or even other/self. The gendering of costume mirrored men's and women's positioning in the political axis of the nation as the status of 'bearer and wearer of national tradition' shifted from women to men once the colony became an independent nation‐state.  相似文献

Eulogius of Córdoba, the principal recorder of the ninth‐century Córdoban martyrs’ movement, copied for posterity a polemic biography of the Prophet Muhammad. The lost original is the earliest such text known in Latin, despite the longstanding tradition of anti‐Islamic polemic in the Greek east. However, textual analysis indicates that Eulogius revised the original biography, and that his revisions were influenced by the polemic of John of Damascus. Eulogius's exposure to John's writings probably came through personal contact with a monk from the monastery of Mar Saba, contact which offers rare evidence of a non‐textual transmission of ideas.  相似文献

The article argues that the century from 1945 is likely to prove seminal in terms of human progress. It marks the period when the human community has to come to terms with its capacity for self‐destruction through the invention of weapons of mass destruction and its ability to exceed the homeostatic capabilities of the global ecosystem in an era of deep socio‐economic divisions. Two‐thirds of the way through this century the progress has been mixed. Nuclear war has been avoided more by luck than by wisdom, there remain risks of nuclear proliferation and it is not evident that humankind has acquired the ability to deal with the destructive potential of bio‐, nano‐ and other emerging technologies. Recognition of the extent of anthropogenic impacts on ecosystem stability is evident, but not at the level necessary for the radical responses required. Even so, there are signs of progress and potential for change, suggesting that the final one‐third of the century will be singularly important in ensuring long‐term emancipation and environmental sustainability.  相似文献

Infant and child skeletons (n = 369) from the pre‐Columbian Grasshopper Pueblo site in east‐central Arizona (US) dating from the 14th century AD were examined macroscopically and with low‐power microscopy. They were studied as a representative example of a typical Mogollon community with respect to frequencies of deficiency and inflammatory diseases. First results revealed very poor living conditions, which are characteristic for this time period in the North American Southwest because of lack of food due to climatic and political changes. Thus, non‐specific stress indicators were frequently observed. In the group of deficiency diseases, anaemia was found in more than 50% of individuals, and in the group of inflammatory diseases, meningeal irritations were diagnosed in more than 70%.

This work is an osteological study of four cases of Colles' fracture from a 3rd–4th century AD British archaeological site. Each case was from an elderly female. Investigation of the degree of malunion suggests lack of effective reduction for these fractures. The poor anatomical outcome appears generally to have resulted in poor functional outcome; detailed anatomical study provided evidence for impairment of function of the distal radioulnar joint, ulnocarpal abutment and scapholunate diastasis, conditions which would probably have caused long‐term residual disability.

In this article, I analyze the so-called ‘discovery of the Pacific’ and its implications for Spanish understanding of global geography, in two of the most important early histories of the early encounter with the New World: the works of Gonzalo Fernández de Oviedo and Francisco López de Gómara. Their general histories of the Indies tackle the Pacific in their accounts of the various expeditions that Spain sent to the Moluccas and Philippines between 1519 and 1542. There we see how both historians struggle to contain the discovery that the Pacific was much broader and emptier than anyone had expected it to be, and thereby prevent it from becoming, in the Spanish imagination, an insurmountable barrier that decisively separated America from Asia. Oviedo is committed to the idea that the Indies are a single tropical expanse that can be successfully spanned by Spanish military might and navigational skill, no matter how large an ocean it contains. Gómara gives up on the unified Indies, embraces the ‘invention of America,’ but miniaturizes the Pacific in order to keep Spain's South Sea ambitions alive. Each in his own way thereby articulates the New World with broader geographies and expansive horizons.  相似文献

Public Land Survey (PLS) data have been widely used in landscape studies of forest and woodlands in the pre‐ and early‐European‐settled Midwestern and Western United States. We aim to reconstruct presettlement forest vegetation at a finer spatial resolution than available from the PLS data using environmental covariates (slope, aspect, geology, and soil type) and the spatially correlated structure of witness tree data. To accommodate various data obtained from multiple sources while explicitly taking into account their spatial structures, we adopt a mixed spatially correlated multinomial logit model within the framework of a generalized linear mixed model. The application of the proposed model is illustrated using the three most abundant tree taxa from PLS data in the Arbuckle Mountains of south‐central Oklahoma. To assess the influence of each source of information on the spatial prediction, we considered four variant multinomial/spatial models and evaluated their relative predictive power using a validation technique. The probabilistic information about the spatial distribution of tree species obtained from different models reveals the need to integrate information about witness tree data as well as environmental covariates, and the nature of tree species; that is, a tendency to cluster in space to share environmental conditions in the reconstruction of the presettlement forest vegetation surface. Los datos sobre el uso y cobertura de tierras del Public Land Survey (PLS) han sido utilizados ampliamente en estudios de paisaje de bosques y de bosques históricos para periodo previo al asentamiento de migrantes europeos en el medio oeste y oeste de los Estados Unidos. Nuestro objetivo es reconstruir la vegetación forestal previa al asentamiento europeo a una resolución espacial más fina que la disponible actualmente en base a datos del PLS, usando covariables ambientales (pendiente, orientación, geología y tipo de suelo) y la estructura de correlación espacial de los datos de los árboles testigos. Para dar cabida a los diversos datos obtenidos de fuentes múltiples, y a la vez teniendo en cuenta explícitamente sus estructuras espaciales, adoptamos un modelo logit multinomial espacial mixto dentro del marco de los modelos mixtos lineales generalizados (GLMM). La aplicación del modelo propuesto es ilustrada con los tres tipos más abundantes de árboles según los datos del PLS para las montañas de Arbuckle en el centro‐sur de Oklahoma, EEUU. Para evaluar la influencia de cada fuente de información sobre la predicción espacial, se consideraron cuatro variantes de los modelos multinomial y espaciales. El poder predictivo de dichos modelos fue evaluado en relación con una técnica de validación. La información probabilística acerca de la distribución espacial de las especies de árboles obtenidos a partir de los diferentes modelos revela que para la reconstrucción de la superficie de la vegetación forestal histórica, es necesario integrar la información sobre los datos de árboles testigos así como las covariables ambientales y la naturaleza de las especies de árboles: es decir, la tendencia de los arboles a agruparse en el espacio para compartir las mismas condiciones ambientales. 公共土地调查(PLS)数据在欧洲人定居美国中西部和西部地区之前以及早期的森林和林地景观研究中得到广泛应用。本文旨在利用环境协变量(坡度、坡向、地貌和土地类型)证据树数据的空间关联结构,重建比PLS数据中更有效的更精细空间分辨率的前殖民期森林植被。为集成多种来源的各类数据,并明确地考虑数据间的空间结构,本文在广义线性混合模型(GLMM)框架下提出了混合空间关联多项Logit模型。以俄克拉荷马州中南部的阿尔布克尔山脉为研究区,提取PLS数据中三种最丰富的树种对模型进行验证。为估计每种信息来源对模型空间预测准确性的影响,本文考虑了4种变异的多项/空间模型并运用验证技术评估它们的相对预测能力。从不同模型获得的树种空间分布的概率信息表明,需要对证据树数据、环境协变量和树种自然属性信息进行集成,也就是说,在重建前殖民期森林植被曲面时,空间上的集聚趋势共享了环境条件。  相似文献

Considerations of Native American warriorhood are likely to conjure images of male‐bodied, masculine individuals. While the majority of formally recognized warriors may have indeed fit this mould, it is also true that female‐bodied/feminine warriors have been historically documented in many places, including North America. Further, even in cases where women were not formally recognized as such, it seems likely that they played offensive and defensive roles on an ‘as needed’ basis, such as on subsistence outings or when their homes and families were under attack. In this paper, we seek to explore the intersection of womanhood and warfare‐related violence at Morton Village (11 F2) and the associated Norris Farms #36 cemetery. This late prehistoric community in the Central Illinois River Valley has been the subject of extensive bioarchaeological interest regarding high levels of skeletally indicated violent trauma. We review this osteological evidence in addition to incorporating mortuary and subsistence perspectives on the ideology and practice of warfare at this time and place. A tripartite approach considering osteological trauma patterns, mortuary commemoration, and new interpretations of community life leads us to suggest an alternate interpretation—one in which Morton Village women are, in at least some instances, considered as active defenders of their community and lifeways rather than passive victims of violence.

This palaeodietary study presents carbon and nitrogen stable isotope data from human and faunal skeletal remains from the Copper Age settlement of Valencina de la Concepción–Castilleja de Guzmán, located in Seville, Spain. Montelirio, the only Valencina–Castilleja human group from which we have obtained reliable palaeodietary results, had a diet based on C3 terrestrial resources, including both plants and animals. The protein component of the diet consisted mainly of meat, milk and dairy products from livestock as well as C3 plant protein from cereals and pulses. This study compares data from Montelirio, the Copper Age group from Valencina–Castilleja, with the published data from other Iberian Late Neolithic–Copper Age (LN‐CA) societies. This comparison reveals a homogeneous diet with some exceptions. Overall, the LN‐CA diet in the Iberian Peninsula consisted mainly of animal proteins from meat, milk and dairy products from livestock as well as C3 plant sources from the characteristic agriculture of the societies of these periods. This study also demonstrates the minor use of aquatic resources from the Neolithic to the Copper Age period in the Iberian Peninsula. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

Excavation of the cemetery of the medieval priory of St. Mary‐without‐Bishopsgate, Spitalfields, London from 1998–2001, recovered the remains of over 10,000 individuals. Following initial assessment, skeleton 19893 was found to have suffered three cranial injuries caused by a sharp edged implement. The remains were those of a middle aged adult male of around 172.4 cm in stature, truncated at the hips by a later feature. The remaining elements were well preserved. The cranial injuries were well healed, suggestive of some degree of post‐traumatic care. Evidence of possible surgery was also found. Soft tissue complications would undoubtedly have followed the assault. Battle related trauma was considered, together with evidence of treatment. Whilst the demographic profile of the individual fitted a plausible one for a professional fighter of the medieval period, no firm evidence of occupation could be provided. The case study indicates both the ability of medieval people to survive major trauma and the wealth of information full analysis of the Spitalfields assemblage will provide the osteological community.
