The field research on five black crested gibbon groups, recently performed at Dazhaizi, Mr. Wuliang, Central Yunnan, China, showed that all groups in the local population consisted of one adult male, two adult females and 2 - 5 sub-adults, juveniles and itfants. The mean group size was 6.2 in August 2003 and 6.4 in August 2005. Two subadult males disappeared from their natal home range and three newborns were given birth in Group 3 (G3) and G4 during this study. The two adult females in G1, G2 and G3 gave births and/or carried babies but at different times. There was no aggressive or dominating behaviour observed between the two adult females. One floating female was first seen in G3's territory on April 15, 2005. The two resident females interrupted her duet with adult male and chased her. We did not observe adult male chased this floating female and she left G3's territory 10 days later. Sub-adult males often kept distance with the family, and they often sang solo bouts in their natal territory before they dispersed. The sub-adult males and females dispersed from natal territory and two adult resident females rejected the third one, which might were the reasons why the black gibbon groups were polygyny in Dazhaizi. 展开更多

Zoige Wetland is one of the largest plateau wetlands in the world. This paper provides a dynamic analysis of spatial and temporal patterns of the wetland in Zoige, Eastern Qinghai-Tibetan Plateau, supported by ERDAS8.7 and ArcGIS9.0. It is the first comparative analysis of a system of rapidly changing wetland with landscape patterns in Zoige, using 3 classified landsat Thematic Mapper images of 1977, 1994 and 2001. The classified images were used to generate wetland distributing maps, and shape index (S), diversity index (H), dominance index (D), evenness index (E), fragmentation index (F) and fractal dimension (Fd) were calculated and analyzed spatiotemporally across pure grazing area in Zoige for each landscape type and in different periods (before 1977, during 1977-1994 and 1994-2001), as well as the driving forces of natural and anthropogenic. The study shows that for a comprehensive understanding of the shapes and trajectories of the shrinking and desertificated land expansion of the wetland, a spatiotemporal landscape metrics analysis in different periods is an improvement than only with landscape changing rates. This type of analysis can also be used to infer underlying social, economic, and political processes that drive the observed wetland forms. The results indicate that wetland patterns can be changed over relatively short periods of time. The total area of lake reduced by 164.86 km^2, grassland extended by 141.74 km^2, semi-marsh extended by 105.94 km^2, marsh reduced by 86.00 km^2 the number of landscape patches reduced by 56, and their average area decreased by 2.68 km^2, the successions within lake, marsh, semi-marsh and grassland were found obviously. S decreased stepwise: D and F increased but H decreased: The changing rate after 1994 was 2.3 to 2.9 times greater than that before. The change of the wetland landscape patterns resulted in the interaction between socio-ceenomic and natural forces of positive and negative aspects; and natural factors affected as assistant aspect. Some important human activities in this period led to the change of the landscape patterns in this region directly. Some measurements made by government and NGO delayed the converting process partly. 展开更多

The development of modern agriculture has resulted in much homogenization of the landscape consisting of large patches of farmland,so small remnant non-crop habitats especially linear corridors play an important role in the conservation of species and the maintenance of ecosystem functions.However,little attention has been paid to the effects of corridors structural characteristics on the plant species restricted to such habitats.In this study,we selected three types of corridors including ditch,hedgerow and road,and analyzed their structural characteristics.The plant species presented in these corridors were investigated,and the species diversity,abundance and frequency were estimated.Moreover,spatial arrangements of corridors were classified into different types to discuss whether there were significant effects of corridor network on plant distribution.The results show that three types of corridors have different effects on plant species composition and diversity.The one-one combined corridor networks and total network associated by three corridors have more complex structural features than each single type of corridor.However,there is no strong correlation between the corridor networks with their plant species.We suggest that carrying out a pointed vegetation survey at corridor intersections to further test the relationships between structural features of corridor and plants is necessary. 展开更多

Innovation is considered an important competitiveness factor for firms and a source of wealth for economies. Innovation appears as a positive value and as a solution to solve social problems and firm's competitiveness. Therefore it is an important subject of policy intervention and territory development, so organizations are encouraged to adopt innovative practices through incentives and innovation policies. This paper aims to propose a new methodological approach for public policy supporting innovation evaluation in a territorial-based analysis. A new methodology which intended to contribute to strengthen and reinforce the innovation effectiveness in firms and territory development resulting from support of public mechanisms. Some economic and sociological studies had showed that Portuguese firms adopt more easily technological innovations (with short-term effects) than organizational and social innovations. In this sense, we will consider innovation public policies effects at firms and how they take available opportunities for innovation. The aim is to know if the concept of innovation spread by these policies is multidimensional (e.g., social, economic and technological) or restricted. We propose to study the factors (internal and external) that affect innovation processes in firms through case studies methodology. This research strategy will show the processes of innovation from within the organizations and analyze the socio-economic context in which organizations operate. 展开更多

Background subtraction is a challenging problem in surveillance scenes. Although the low-rank and sparse decomposition(LRSD) methods offer an appropriate framework for background modeling, they fail to account for image's local structure, which is favorable for this problem. Based on this, we propose a background subtraction method via low-rank and SILTP-based structured sparse decomposition, named LRSSD. In this method, a novel SILTP-inducing sparsity norm is introduced to enhance the structured presentation of the foreground region. As an assistance, saliency detection is employed to render a rough shape and location of foreground. The final refined foreground is decided jointly by sparse component and attention map. Experimental results on different datasets show its superiority over the competing methods, especially under noise and changing illumination scenarios. 展开更多

This article, which utilizes the quantitative social-background approach, sets as its objective to empirically discern correlations between the behavior of the Jewish political elite, embodied in the Jewish Agency for Palestine in the period from 1921 to 1948, and the following social-background variables: age, foreign travel, occupation as a path to political power, regional affiliation, ideology, and political opportunity, of the JAE membership. Diversity of the social-background variables and, particularly, the multitude of languages they knew, explain, to a considerable extent, firstly, the wide variety of their social, political and economic views, and, secondly, the elite's resort to direct contact with Western governments and peoples in communicating and promoting their political ideology, thus facilitating the realization of the Zionist project. 展开更多

Pedestrian detection is one of the most important problems in the visual sensor network. Considering that the visual sensors have limited cap ability, we propose a pedestrian detection method with low energy consumption. Our method contains two parts: one is an Enhanced Self-Organizing Background Subtraction (ESOBS) based foreground segmentation module to obtain active areas in the observed region from the visual sensors; the other is an appearance model based detection module to detect the pedestrians from the foreground areas. Moreover, we create our own large pedestrian dataset according to the specific scene in the visual sensor network. Numerous experiments are conducted in both indoor and outdoor specific scenes. The experimental results show that our method is effective. 展开更多

China is the only one country in the world with more than one hundred million people who aged over 60. With the dramatically increasing of population aging speed, the traditional endowment pattern with the element of family model has a weakening trend and does not satisfy the demand of urban elderly diversified and multi-level pension. Thus, pensions that occupy at home are becoming the best choice of the urban pension mode in China. The paper will describe the meaning, situation and prospects of the home endowment and demonstrate the significance of developing the home endowment project in China. Additionally, the paper will discuss the future endowment model from the aspects of the government organization, scientific planning and functional shifts. 展开更多

Distribution patterns of plant species are believed to be impacted by small-scale habitat heterogeneity. However, there have been few comparative studies examining how woody vegetation composition and diversity varies with aspects of different orientations in the Trans-Himalayan region at a local scale. Here, we examined the effects of incoming solar radiation on variation in woody species composition and compared the diversity between the northeast- and southwest-facing slopes in a Trans-Himalayan valley of Nepal. We also examined the implicit interactions between slope orientation and land use in determining the compositional variations between the slopes. We selected two pairs of northeast- and southwest-facing slopes where the first pair has a similar land use and differs in exposure only(Pisang site) while the other pair has clear differences in land use in addition to slope exposure(Braka site). In each site, we sampled 72 plots(36 on each slope) in which the presence and absence of woody species, environmental variables, and disturbance were recorded. Correspondence Analysis(CA) results suggested that the woody species composition significantly varied between northeast- and southwest-facing slopes at both sites, and was significantly correlated with measured environmental variables such as radiation index, altitude, and canopy openness. In the Braka site,mean alpha diversity was significantly higher on southwest-facing slopes. In contrast, beta diversity and gamma diversity were greater on northeast-facing slopes at both sites. Our results suggest that topographic variables(e.g., radiation index) affect species composition between the slopes, likely due to their influence on small scale abiotic environmental variables. However, the effects of land use, such as livestock browsing/grazing may interact with the effects of slope exposure, effectively reducing differences in species composition within slopes but enhancing the differences in beta diversity between contrasting slopes in the Braka. We conclude that slope orientation and land use are important factors in structuring the woody species composition and diversity in the arid Trans-Himalayan region. We suggest that both environmental and land use variables should be taken into consideration in future studies on plant community structure along the cultural landscapes. 展开更多

Listening comprehension plays a crucial and necessary part in people's daily communication and Second Language Acquisition (SLA). It is an important way to communicate with others; also it is the foundation of mastering a foreign language. However, the higher vocational students usually lack the background information about the listening materials and seldom know how to make inferences according to the specific contexts. The author conducted an empirical study lasting one semester in Higher Vocational College of Dahongying University trying to apply Relevance Theory to listening comprehension and guide listening comprehension learning within the framework of Relevance Theory to finally improve higher vocational students' ability of listening comprehension. 展开更多

A 71-year-old woman was referred to our department complaining of painless progressive jaundice for the last 3 too. Magnetic resonance imaging and magnetic resonance cholangiopancreatography (MRCP) showed the ectopic hepatopancreatic ampulla draining into the fourth part of the duodenum adjacent to the duodenojejunal flexure; the irregular morphology of the duodenojejunal flexure likely due to a soft tissue mass. Laparotomy confirmed the presence of the abnormal ampulla of Vater located at the fourth part of the duodenum and a soft tissue tumor about 6 cm × 5 cm×5 cm with a peduncle adjoining the ampulla. Resection of the tumor, including some peripheral tissue, and a Roux-Y loop anastomosis choledochojejunostomy were performed. Pathological examination indicated an intestinal villous adenoma accompanied by severe dysplasia and focal canceration. Periampullary carcinoma with ectopic ending of the Vater's ampulla into the fourth part of the duodenum is rather rare. The embryonic genetic background of this anomaly has not yet been fully explained. It is worth mentioning that MRCP is useful for demonstrating anomalies and anatomic variants of the biliary tract system and pancreatic duct. 展开更多

Natural environments contribute to people’s perception,preference and health restoration.Many researchers have focused either on the positive effects of overall rural environments on stress recovery or concentrated on the perception and preference aspects of the rural landscape,but few have integrated perception,preference and stress recovery simultaneously.This paper developed a framework which includes 11 elements and 38 element components related to Linpan,China,and distributed it online as part of a survey.As a result,a total of 324 valid questionnaires were collected.The questionnaire included demographic details,perception and preference degree for Linpan,as well as self-estimations of stress recovery.Stepwise multiple linear regression was employed,and revealed 16 significant predictors for the perception,preference and stress recovery in rural environments.In terms of elements,atmosphere and imagery were the two elements that could be best perceived,while woodland,farmland,water,residence and road were the five most important elements for the preference.Moreover,seven elements were also identified as significant predictors for stress recovery.Among the element components,tranquility as well as road and water proximity were the two significant predictors for perception,while wide visibility as well as woodland and residence blending contributed significantly to stress recovery.The five element components of woodland interior,vegetable field,stream,courtyard space and branch road each had a significantly predictive ability for preference and stress recovery.These findings extend the understanding of the perception,preference and restorative properties of rural environments through the combination of elements and element components in Linpan of Western Sichuan,helping to improve the quality and characteristics of rural external and internal environments and create health-promoting environments. 展开更多

The objective of this research is the rapid reconstruction of ancient buildings of historical importance using a single image. The key idea of our approach is to reduce the infinite solutions that might otherwise arise when recovering a 3D geometry from 2D photographs. The main outcome of our research shows that the proposed methodology can be used to reconstruct ancient monuments for use as proxies for digital effects in applications such as tourism, games, and entertainment, which do not require very accurate modeling. In this article, we consider the reconstruction of ancient Mughal architecture including the Taj Mahal. We propose a modeling pipeline that makes an easy reconstruction possible using a single photograph taken from a single view, without the need to create complex point clouds from multiple images or the use of laser scanners. First, an initial model is automatically reconstructed using locally fitted planar primitives along with their boundary polygons and the adjacency relation among parts of the polygons. This approach is faster and more accurate than creating a model from scratch because the initial reconstruction phase provides a set of structural information together with the adjacency relation, which makes it possible to estimate the approximate depth of the entire structural monument. Next, we use manual extrapolation and editing techniques with modeling software to assemble and adjust different 3D components of the model. Thus, this research opens up the opportunity for the present generation to experience remote sites of architectural and cultural importance through virtual worlds and real-time mobile applications. Variations of a recreated 3D monument to represent an amalgam of various cultures are targeted for future work. 展开更多
