The changing patterns of watersheds in a landscape, driven by human activities, play an important role in non-point source pollution processes. This paper aims to improve the location-weighted landscape contrast index using remote sensing and GIS technology to account for the effects of scale and ecological processes. The hydrological response unit(HRU) with a single land use and soil type was used as the smallest unit. The relationship between the landscape index and typical ecological processes was established by describing the influence of the landscape pattern on non-point source pollution. To verify the research method, this paper used the Yanshi River basin as a study area. The results showed that the relative intensity of non-point source pollution in different regions of the watershed and the location-weighted landscape contrast index based on the minimum HRU can qualitatively reflect the risk of regional nutrient loss. 展开更多

Thermal treatment technologies hold an important niche in the remediation of hydrocarbon- contaminated soils and sediments due to their ability to quickly and reliably meet cleanup standards. However, sustained high temperature can be energy intensive and can damage soil properties. Despite the broad applicability and prevalence of thermal remediation, little work has been done to improve the environmental compatibility and sustainahility of these technologies. We review several common thermal treatment technologies for hydrocarbon-contaminated soils, assess their potential environmental impacts, and propose frameworks for sustainable and low-impact deployment based on a holistic consideration of energy and water requirements, ecosystem ecology, and soil science. There is no universally appropriate thermal treatment technology. Rather, the appropriate choice depends on the contamination scenario (including the type of hydrocarbons present) and on site-specific considerations such as soil properties, water availability, and the heat sensitivity of contaminated soils. Overall, the convergence of treatment process engineering with soil science, ecosystem ecology, and plant biology research is essential to fill critical knowledge gaps and improve both the removal efficiency and sustainability of thermal technologies. 展开更多

Assessing the adsorption properties of nanoporous materials and determining their structural characterization is critical for progressing the use of such materials for many applications, including gas storage. Gas adsorption can he used for this characterization because it assesses a broad range of pore sizes, from micropore to mesopore. In the past 20 years, key developments have been achieved both in the knowledge of the adsorption and phase behavior of fluids in ordered nanoporous materials and in the creation and advancement of state-of-the-art approaches based on statistical mechanics, such as molecular sim- ulation and density functional theory. Together with high-resolution experimental procedures for the adsorption of suhcritical and supercritical fluids, this has led to significant advances in physical adsorp- tion textural characterization. In this short, selective review paper, we discuss a few important and central features of the underlying adsorption mechanisms of fluids in a variety of nanoporous materials with well-defined pore structure. The significance of these features for advancing physical adsorption charac- terization and gas storage applications is also discussed. 展开更多

Based on investigations of 112 Chinese firms and studies on foreign leading corporations, a theoretical framework of dynamic capabilities based strategy innovation (SI) is put forward. Several large firms in China winning through SI were studied empirically. This paper complements previous publications on the theories of innovation and strategy. This work's findings will be useful for managers interested in our approach, which highlights the importance of SI and focuses on and points out the major pitfalls in the innovation processes. Implementing the dynamic capabilities based strategy innovation can effectively cultivate and develop core competences of corporations. It is concluded that implementing SI is the only path for Chinese enterprise growth in the intensified competition in the knowledge economy. 展开更多

The accounting result from science and technology innovation and the development of productivity, with management modes and financial reforms as its opportunity and the operation of international capital, as well as economic integration helping improve it. An invention, a president, the occurrence of an organization, a historical lesson may directly or indirectly change accounting regulations, and even trigger an accounting revolution. We will put a variety of significant impacts on an accounting, so as to get a fundamental understanding of the close relationship between such events and accounting events, including innovation of accounting theory, and accounting practice; we adopted the "table-style" form of papers, with many self-evident and intuitive tables, we compile a series of major historical events reasonably. Only in accordance with evolution of objective environment, can we design proper accounting practice, and thus innovate and develop accounting. 展开更多

In this paper the application of spatialization technology on metadata quality check and updating was dis-cussed. A new method based on spatialization was proposed for checking and updating metadata to overcome the defi-ciency of text based methods with the powerful functions of spatial query and analysis provided by GIS software. Thismethod employs the technology of spatialization to transform metadata into a coordinate space and the functions ofspatial analysis in GIS to check and update spatial metadata in a visual environment. The basic principle and technicalflow of this method were explained in detail, and an example of implementation using ArcMap of GIS software wasillustrated with a metadata set of digital raster maps. The result shows the new method with the support of interactionof graph and text is much more intuitive and convenient than the ordinary text based method, and can fully utilize thefunctions of GIS spatial query and analysis with more accuracy and efficiency. 展开更多

There have never been more ways for us to "communicate" than what we may have today as we keep developing new technologies that allow us with alternative forms of interaction other than face-to-face conversation. Our age indeed distinguishes itself by its ever more rapid transformations in the kinds of mediation for such encounters. But, especially when they are new, technologies may deeply affect how we see the world, our communities, our relationships, and ourselves. For, as people usually respond to new media with much excitement as well as a big amount of confusion, and these media may conduct to social and cultural reorganization, they should as well incite more sober reflections about such changes before they become so taken for granted to appear as almost "invisible" 展开更多

With the announcement of the sheep clone Dolly as the breakthrough in the biotechnology in news media around the turn of the twenty-first century, the rising issue of human clones in its development and the controversially bioethical issues ensued, Kazuo Ishiguro in Never Let Me Go (2005) focuses his attention, in the area of cell therapy, on how human clones, since produced, lead their model lives and face their deaths, in order that his readers may better understand the meanings of life and death, and that they may stay in a far closer relationship with their family and friends than ever. In this essay, I examine, in two worlds, the normals' and the clones', paralleling each other, the true meanings of being human and their lives through the perspective of Jacques Derrida's deconstruction; and I argue that Ishiguro misspeaks to his readers the true meanings of life and death especially through the clones' perspective and brings them to his readers' hearts further realistically. In Derrida's nature-culture structurality of the clones, it is Kathy H. who comes as center into which the other clones come as freeplay in the structurality of the real world, where it is normals who come as center into which clones come as freeplay under the structurality of power in the institutions where the clones' culture comes as center into which Miss Emily's ruling comes as freeplay by the structurality of authorship where the author comes as center into which the novel comes as freeplay. 展开更多

This research drew from social learning and international development literature. The purpose of this community research was to trace the spread and impact of sweetpotato flour in two rural communities in Papua New Guinea. Research strategy was participatory learning and action utilizing participatory mapping. The paper mapping process was documented using a video recorder and field notes. Geographic Information Systems technology was then used to incorporate local spatial knowledge on scale maps to show spread of knowledge. The main finding was the identification of social networks through tracking of sweetpotato knowledge: identifying who used the knowledge and whether there were any modifications, the location of those who used the knowledge and whether this was shared and with whom. Most significant was the enabling factors that strengthened existing and potential future networks. Community leadership styles determine success of development projects. Rural communities are diverse needing participatory multi-layered methodologies that are people oriented for agricultural technologies to be learnt and utilized for improved livelihood. 展开更多

Duodenal trauma is uncommon but nowadays seen more and more frequently due to the increased automobile accidents and violent events. The management of duodenal trauma can be complicated, especially when massive injury to the pancreatic-duodenal-biliary complex occurs simultaneously. Even the patients receive surgeries in time, multiple postoperative complications and high mortality are common. To know and manage duodenal trauma better, we searched the recent related literature in PubMed by the keywords of duodenal trauma, therapy, diagnosis and abdomen. It shows that because the diagnosis and management are complicated and the mortality is high,duodenal trauma should be treated in time and tactfully.And application of new technology can help improve the management. In this review, we discussed the incidence,diagnosis, management, and complications as well as mortality of duodenal trauma. 展开更多

Interacting with digital contents in 3 D is an essential task in various applications such as modeling packages, gaming, virtual reality, etc. Traditional interfaces using keyboard and mouse or trackball usually require a non-trivial amount of working space as well as a learning process. We present the design of EZ-Manipulator, a new 3 D manipulation interface using smartphones that supports mobile, fast, and ambiguity-free interaction with 3 D objects. Our system leverages the built-in multi-touch input and gyroscope sensor of smartphones to achieve 9 degrees-of-freedom axis-constrained manipulation and free-form rotation.Using EZ-Manipulator to manipulate objects in 3 D is easy. The user merely has to perform intuitive singleor two-finger gestures and rotate the hand-held device to perform manipulations at fine-grained and coarse levels respectively. We further investigate the ambiguity in manipulation introduced by indirect manipulations using a multi-touch interface, and propose a dynamic virtual camera adjustment to effectively resolve the ambiguity. A preliminary study shows that our system has significant lower task completion time compared to conventional use of a keyboard–mouse interface, and provides a positive user experience to both novices and experts. 展开更多

After reviewing the value chain theory and resource view theory, it is shown that the technological innovation selection of enterprise should keep to relative value structure and technical rules, at the same time takes their own resource and capability as ref- erence. In fact, it synthesizes the viewpoints of positioning school and resource school. A model for the selection path of innovation is founded and in which the theory analysis is deepened by means of example of development of Dongfang Turbine Co., Ltd. (DTC) wind power industry. 展开更多
