House Number

House number is one important city geocoding method, which has the most fundamental positioning role and also is the main information carrier in digital city construction. Because traditional house number system has faultiness and city spatial layout has changed a lot with urbanization process in china, house numbers are chaotic in many cities. It is very inconvenient for city management and information construction. It is urgent to reconstruct scientific house number system. First, the authors introduce the advantages and disadvantages of main domestic and foreign house number systems, analyzed the spatial characters of house number, and compared the merits and demerits of block geocoding and street geocoding method. Then, they point out that street is the appropriate spatial framework for house number system of our country. Next they analyzed the spatial localization characters of the house number geocoding within street framework, and pointed out the shortages of traditional serial number and distance number. Then, they put forward and elaborate the block segmenting method of house number. At last, on the assumption that each block has 100 numbers, the figures of block segmenting are displayed. The block segmenting method can ensure the robustness of house number system. It further strengthens the order and localization role of house number and realizes binding house numbers to street block segment. House numbers will not become chaos with the increases and decreases or changing hands of the buildings in the system.

The elementary school teacher of today needs to have a comprehensive view of eleme ntary mathematics. The present emphasis on the “new” mathematics requires an understanding of number systems such as the natural number system, the whole number system, the rational number system, and the real number system, together with an understanding of some elementary concepts from geometry. This understanding of mathematics can no longer be limited to specific areas covered at one level in graded material, but should encompass the structures of different number systems. One must recognize the role of a specific topic in mathematics in relation to the overall structure of the systems under consideration. Failure to do this often leads to confusion for a student who must relearn or radically alter a previously learned mathematical principle. Such a situation should be avoided.

The article considers the role of trust in the economy, the mechanisms of its accumulation and the possibility of using it as one of the growth factors in the future. The advantages and disadvantages of measuring the level of generalized trust using two alternative questions — about trusting people in general and trusting strangers — are analyzed. The results of the analysis of dynamics of the level of generalized trust among Russian youth, obtained within the study of the Institute for National Projects in 10 regions of Russia, are presented. It is shown that there are no significant changes in trust in people in general during the study at university. At the same time, the level of trust in strangers falls, which can negatively affect the level of trust in the country as a whole, and as a result have negative effects on the development of the economy in the future. Possible causes of the observed trends and the role of universities are discussed. Also the question about the connection between the level of education and generalized trust in countries with different quality of the institutional environment is raised.

IIntroduction: Pancreatic Neuroendocrine Tumours (p-NETs) are an important disease entity and comprise of peptide-secreting tumours often with a functional syndrome. : Accounting for a small percentage of all pancreatic tumours, they have a good overall survival rate when diagnosed early, with surgery being curative. The role of nuclear medicine in the diagnosis and treatment of these tumours is evident. However, the vast majority of patients will require extensive imaging in the form of conventional radiological techniques. It is important for clinicians to have a fundamental understanding of the p-NET appearances to aid prompt identification and to help direct management through neoplastic staging. Methods: This article will review the advantages and disadvantages of conventional radiological techniques in the context of p-NETs and highlight features that these tumours exhibit. Conclusion: Pancreatic neuroendocrine tumours are a unique collection of neoplasms that have markedly disparate clinical features but similar imaging characteristics. Most p-NETs are small and welldefined with homogenous enhancement following contrast administration, although larger and less welldifferentiated tumours can demonstrate areas of necrosis and cystic architecture with heterogeneous enhancement characteristics. : Prognosis is generally favourable for these tumours with various treatment options available. However, conventional radiological techniques will remain the foundation for the initial diagnosis and staging of these tumours, and a grasp of these modalities is extremely important for physicians.

Abstract The goal of glioma surgery is maximal safe resection in order to provide optimal tumor control and survival benefit to the patient. There are multiple imaging modalities beyond traditional contrast-enhanced magnetic resonance imaging (MRI) that have been incorporated into the preoperative workup of patients presenting with gliomas. The aim of these imaging modalities is to identify cortical and subcortical areas of eloquence, and their relationship to the lesion. In this article, multiple modalities are described with an emphasis on the underlying technology, clinical utilization, advantages, and disadvantages of each. functional MRI and its role in identifying hemispheric dominance and areas of language and motor are discussed. The nuances of magnetoencephalography and transcranial magnetic stimulation in localization of eloquent cortex are examined, as well as the role of diffusion tensor imaging in defining normal white matter tracts in glioma surgery. Lastly, we highlight the role of stimulated Raman spectroscopy in intraoperative histopathological diagnosis of tissue to guide tumor resection. Tumors may shift the normal arrangement of functional anatomy in the brain; thus, utilization of multiple modalities may be helpful in operative planning and patient counseling for successful surgery.

Development And Management

The continuous growth of cities brings out various concerns for improved development and management of the multifaceted urban systems, including those of resilience and smartness. Despite the many significant efforts in the research field, both notions remain changeable, thus retaining the lack of commonly accepted conceptual and terminological frameworks. The paper’s research goals are to designate the current direct and indirect links in the conceptualizations and research trends of the resilience and smart city frameworks and to prove the potential of the conceptual convergence between them in the context of urban systems. The application of a semi-systematic literature review, including bibliometric evidence and followed by content analysis, has led to the observation that as the resilience discourse opens up to embrace other dimensions, including technology, the smart city research turns its interest to the perspective of urban protection. Therefore, both concepts share the goal for urban sustainability realized through specific capacities and processes and operationalized with the deployment of technology. The paper’s findings suggest that the conceptual and operational foundations of these two concepts could support the emergence of an integrated framework. Such a prospect acknowledges the instrumental role of the smart city approach in the pursuit of urban resilience and unfolds a new model for sustainable city management and development.

This article builds a framework for a relational approach to segregation that emphasizes structures of interactions, transactions, and ties between and within social categories. Rather than explaining segregation with dominants imposing formal rules or homophilic people sorting themselves, I highlight segregation’s emergence amid dueling control efforts among actors with malleable categorical identities. And rather than assuming segregation necessarily fuels cycles of inequality or persecution, I identify nuanced advantages and disadvantages for different actors in social conflict. I also explore an underappreciated role of institutions in segregation: They guide relations across different domains of activity that may have different degrees of segregation. An overarching theme is that segregation is not a specific thing with regular causes and effects but an inherently contradictory structural feature of relations that evolves as actors struggle for control.

AbstractA problem for a circular economy, embedded in its policies, tools, technologies and models, is that it is driven by the interests and needs of producers, rather than customers and users. This opinion paper focuses on an alternative form of governance—agreements, which thanks to their bargaining approach brings actors from across the value chain into the policy process. The purpose of this opinion paper is to uncover and analyse the potential of such agreements for a circular economy. Circular agreements aim at increasing the circulation of materials and are an emerging form of political governance within the EU. These agreements have different names, involve different actors and govern in different ways. However, circular agreements seem to work when other types of regulations fail to establish circulation. These agreements bring actors together and offer a platform for negotiating how advantages and disadvantages can be redistributed between actors in a way that is more suitable for a circular economy. However, circular agreements are dependent on other policy instruments to work and can generate a free-rider problem with uninvolved actors. The agreements may also become too detailed and long term, which leads to problem shifting and lock-ins, respectively.

Some are born to computer literacy, while others have literacy thrust upon them! Students who comprise the next generation of political scientists and public administrators will, in many cases, fall into the latter category. This article concerns the role of university training programs in meeting the increasing demands for microcomputer skills.The January, 1984 issue of Public Administration Review included five articles concerning microcomputers in local government. These articles anticipate “major changes in the way local governments organize and the means by which they carry out operations,” as a result of microcomputer technology. Predicting a significant impact of microcomputers in local government, the International City Management Association has also published a major monograph on microcomputer use (Griesemer, 1984).
