    The internationalization of policy regimes and the reorganization of the state have provided new opportunities for cities to bypass nation-state structures and work with other cities internationally. This provides greater opportunity for cities to learn from each other and could be an important stimulus to the transfer of policies across the globe. Few studies exist however which focus on the processes that shape the search for policy lessons and how they are affected by the institutional con...

    2010-01-01

    Community policing programmes are widely perceived and promoted as an important solution for the pressing problems of insecurity in contemporary Latin American cities, and for improving citizen-police relationships. By drawing on the results of empirical fieldwork conducted in Mexico City, the article presents a critical analysis of the local community policing effort. The article demonstrates that this policing effort is overly determined by a local context, characterized by clientelism, pol...

    Full Text Available This article contributes, in the form of theoretical discussion, to the review of relevant methods for determination of city's spatial structure through the retrospective of continuity/discontinuity of understanding their spatial structure from the school of classical sociology to the sustainable development paradigm. Particularly, authors underline significance and analyze main theories and their models (social-ecology, economics, system science and geography in the researching of spatial structure of the cities. They conclude that urban settlements spatial structure is resultant of complex dynamically-developing processes between settlements networks and systems on the one, and also between their internal components, on the other side. In their essence, cities are not statistical category, but complex and dynamical system whose structure reflects the relations between economic, social and cultural organization of life, adapted to the geographic environment.

    2007-12-01

    At the southwest margin of the Isthmus of Panama, the Cocos, Nazca and Panama Microplate join in a triple junction. In this tectonic setting, the Panama Fracture Zone (PFZ) which bounds the Nazca and Cocos plate, subducts in an oblique and shallow manner. This zone is one of the most active seismic areas of Central America. On July 18, 1934, the largest earthquake in Panama in historical times (Ms= 7.7) occurred in its northern region. This event caused extensive damage to towns located in the border of Panama and Costa Rica and during the two subsequent days, six aftershocks with magnitude greater than 6.0 were recorded. David City, with 130,000 inhabitants is the most important urban center in southwestern Panama and lies at the northern end of the PFZ. This city was impacted by the strong destructive earthquakes (Ms>7.0) that took place in 1879 and 1934, both with epicenters located on the northern terminus of the PFZ. In this work, we collected and digitized historical seismograms to measure the centroid moment tensor (CMT) from the main 1934 earthquake. Additionally, we gathered new macroseismic information to create improved and more complete isoseismals maps of the 1879 and 1934 events. We determined the probabilistic seismic hazard for David City using records of historical and recent seismicity and the characteristics of local faults. The hazard computation results are presented as peak iso-acceleration curves for rock/hard soil for a recurrence time of 500 years. An elastic response spectrum was obtained with a uniform exceedance probability of 10% in 50 years with one degree of freedom and 5% of damping. Our results indicate maximum peak ground acceleration (PGA) in downtown David of 3.8 and 4.5 m/s2 with a probability annual exceedance of 0.002 and 0.001, respectively. Structural vulnerability was determined analyzing the quality and construction design of housing, buildings, and critical facilities as well as the type of soil where these structures

    Full Text Available Abstract Background Fatal heroin overdose is a significant cause of mortality for injection drug users (IDUs. Many of these deaths are preventable because opiate overdoses can be quickly and safely reversed through the injection of Naloxone [brand name Narcan], a prescription drug used to revive persons who have overdosed on heroin or other opioids. Currently, in several cities in the United States, drug users are being trained in naloxone administration and given naloxone for immediate and successful reversals of opiate overdoses. There has been very little formal description of the challenges faced in the development and implementation of large-scale IDU naloxone administration training and distribution programs and the lessons learned during this process. Methods During a one year period, over 1,000 participants were trained in SKOOP (Skills and Knowledge on Opiate Prevention and received a prescription for naloxone by a medical doctor on site at a syringe exchange program (SEP in New York City. Participants in SKOOP were over the age of 18, current participants of SEPs, and current or former drug users. We present details about program design and lessons learned during the development and implementation of SKOOP. Lessons learned described in the manuscript are collectively articulated by the evaluators and implementers of the project. Results There were six primary challenges and lessons learned in developing, implementing, and evaluating SKOOP. These include a political climate surrounding naloxone distribution; b extant prescription drug laws; c initial low levels of recruitment into the program; d development of participant appropriate training methodology; e challenges in the design of a suitable formal evaluation; and f evolution of program response to naloxone. Conclusion Other naloxone distribution programs may anticipate similar challenges to SKOOP and we identify mechanisms to address them. Strategies include being flexible in

    Pervasive infrastructures, such as cell phone networks, enable to capture large amounts of human behavioral data but also provide information about the structure of cities and their dynamical properties. In this article, we focus on these last aspects by studying phone data recorded during 55 days in 31 Spanish cities. We first define an urban dilatation index which measures how the average distance between individuals evolves during the day, allowing us to highlight different types of city structure. We then focus on hotspots, the most crowded places in the city. We propose a parameter free method to detect them and to test the robustness of our results. The number of these hotspots scales sublinearly with the population size, a result in agreement with previous theoretical arguments and measures on employment datasets. We study the lifetime of these hotspots and show in particular that the hierarchy of permanent ones, which constitute the `heart' of the city, is very stable whatever the size of the city. The spatial structure of these hotspots is also of interest and allows us to distinguish different categories of cities, from monocentric and ``segregated'' where the spatial distribution is very dependent on land use, to polycentric where the spatial mixing between land uses is much more important. These results point towards the possibility of a new, quantitative classification of cities using high resolution spatio-temporal data.

    How are economic activities linked to geographic locations? To answer this question, we use a data-driven approach that builds on the information about location, ownership and economic activities of the world's 3,000 largest firms and their almost one million subsidiaries. From this information we generate a bipartite network of cities linked to economic activities. Analysing the structure of this network, we find striking similarities with nested networks observed in ecology, where links represent mutualistic interactions between species. This motivates us to apply ecological indicators to identify the unbalanced deployment of economic activities. Such deployment can lead to an over-representation of specific economic sectors in a given city, and poses a significant thread for the city's future especially in times when the over-represented activities face economic uncertainties. If we compare our analysis with external rankings about the quality of life in a city, we find that the nested structure of the cit...

    Full Text Available The absorption of structural and cohesion funds is one of Romania’s top priorities. Nevertheless, with a very weak absorption rate (11.47% as of December 31st 2012, according to official data, the overall situation is particularly alarming, considering the slow pace of effective project implementation and expenditure recovery from the European Commission. This text proceeds to provide an analysis of the realities of managing structural funds in Romania, focusing on the causes and factors that lead to weak absorption and on the experience of the main actors and institutions involved in this process. Our interests are, in particular, connected to the following: (1 to identify and analyze the most important aspects of structural funds management in Romania after six years of accessing and implementing projects; (2 to evaluate the capacity of the institutions involved in the structural funds management system with a focus on the level of turnover of institutions involved in the process; and (3 to identify and present added-value experiences and lessons learned from both institutions and beneficiaries (public authorities involved in this process.

  1. Hurricane Sandy and Adaptation Pathways in New York: Lessons from a First-Responder City

    Science.gov (United States)

    Rosenzweig, Cynthia; Solecki, William

    2014-01-01

    Two central issues of climate change have become increasingly evident: Climate change will significantly affect cities; and rapid global urbanization will increase dramatically the number of individuals, amount of critical infrastructure, and means of economic production that are exposed and vulnerable to dynamic climate risks. Simultaneously, cities in many settings have begun to emerge as early adopters of climate change action strategies including greenhouse gas mitigation and adaptation. The objective of this paper is to examine and analyze how officials of one city - the City of New York - have integrated a flexible adaptation pathways approach into the municipality's climate action strategy. This approach has been connected with the City's ongoing response to Hurricane Sandy, which struck in the October 2012 and resulted in damages worth more than US$19 billion. A case study narrative methodology utilizing the Wise et al. conceptual framework (see this volume) is used to evaluate the effectiveness of the flexible adaptation pathways approach in New York City. The paper finds that Hurricane Sandy serves as a ''tipping point'' leading to transformative adaptation due to the explicit inclusion of increasing climate change risks in the rebuilding effort. The potential for transferability of the approach to cities varying in size and development stage is discussed, with elements useful across cities including the overall concept of flexible adaptation pathways, the inclusion of the full metropolitan region in the planning process, and the co-generation of climate-risk information by stakeholders and scientists.

    The concept of smart city gives an excellent resolution to construct and develop modern cities, and also demands infrastructure construction. How to build a safe, stable, and highly efficient public transportation system becomes an important topic in the process of city construction. In this work, we study the structural and robustness properties of transportation networks and their sub-networks. We introduce a complementary network model to study the relevance and complementarity between bus network and subway network. Our numerical results show that the mutual supplement of networks can improve the network robustness. This conclusion provides a theoretical basis for the construction of public traffic networks, and it also supports reasonable operation of managing smart cities.

    2008-01-01

    Full Text Available The structural transformations of Slovenian coastal cities are a form of content development strategies that have been dictated by different city actors throughout the history. Because of the process of industrialisation, the coastal region adopted a new structure in the form of industrial structures. Today, these structures are left without appropriate contents and present degraded areas of the city that are subject to the interest of the capital. The post-war period of functionalism attempted to introduce in the area the conditions for social reformation of the social structure, architects were designing for the needs of the working class, which inhabited the newly built residence areas. In the sixties of the 20th century, a new typology of residential tall buildings, which began to rise vertically, emerged from horizontal industrial structures. At the level of organisation of space, the period after transition brought in the coastal space a widespread state of chaos, as spatial interventions were made on the basis of the interest of capital and to a lesser degree on the basis of expert guidelines. Urbanism as a discipline is not flexible enough to regulate the swift transformations of the forms of capital. As a result, the capital is spreading unrestrictedly across all limits of the city.

    Waste reduction and recycling at the city level will acquire greater significance in the near future due to rising global volumes of waste. This paper seeks to identify policy-relevant drivers for successful promotion of waste reduction and recycling. Factors influencing the success of waste reduction and recycling campaigns are identified. Two case study cities in Japan which depict the successful use of the 3Rs (reduce, reuse and recycle) at the municipal level are presented. In these cases, the existence of incinerators, which are generally considered as disincentives for recycling, was not functioning as a disincentive but rather as an incentive for waste reduction. Owing to the high cost of incineration facilities, the movement to close incinerators has become a strong incentive for waste reduction and recycling in these two cities. The study suggests that careful consideration is necessary when making decisions concerning high-cost waste treatment facilities with high installation, maintenance and renewal outlays. In addition, intensive source separation and other municipal recycling initiatives have a high potential for producing positive results. PMID:25023986

  8. City structure – the phenomenon of exclusion of space

    Directory of Open Access Journals (Sweden)

    Marta Marta Szejnfeld

    2014-10-01

    Full Text Available A special feature of spaces with urban character is the phenomenon of exclusion, which refers both to the space and the community, causing deformation and the disappearanceof the unity of the urban structure as a whole. Spatial segregation processes – resulting from social polarization – causes low–income or marginalized groups lack of access to a high–quality urban space. Excluded spaces have become a constant component of visual reality in which gated communities, guarded buildings, or corporation complexes have divided the urban fabric, and in opposition to the city, are capturing more and more spaces. The result of the appearance of the excluded spaces is the lack of the right to the city for all its inhabitants. Foresaid lack deprives the participant of the possibility of observation and penetration the urban structure, which further deepens the sense of alienation. In such spatial conditions the longing for re–evoking the idea of a sustainable city is born. Theessence is therefore an insightful diagnosis of the impact of uncontrolled processes shaping the urban structure deepening segregation and exclusion from the urban space.Keywords: urban transformation, exclusion, inhabitants

    2010-08-01

    Abstract We investigate the structural properties of Chinese city airline network (CCAN), where nodes and edges denote cities and direct flights. The degree distribution follows a double power law and a clear hierarchical layout is observed. The population exhibits a weakly positive correlation with the number of flights, yet it does not show obvious correlation with the transportation flow. The distance is an important parameter in CCAN, that is, the number of flights decays fast with the increasing of the distance. In comparison, the tertiary industry has the most important influence on the Chinese air passenger transportation. Statistically speaking, when the tertiary industry value increases by 1%, the next period's volume will increase by 0.73%.

  11. Lessons learned during decommissioning of underground structures, systems and components

    International Nuclear Information System (INIS)

    The following examples present some important lessons learned, some brief technical details and a description of problems encountered in the past in various decommissioning projects related to the removal of underground SSCs. Some cases refer to embedded components. The situations described here are typical of the types of difficulty that can arise when planning for or implementing the removal of underground SSCs as an element of the decommissioning process. The information presented here is not intended to be exhaustive and the reader is encouraged to evaluate the applicability of the specific lessons learned to their own particular decommissioning project or activity. It is not the intention of this annex to identify projects for criticism but rather to enhance future operations planning and implementation in order to reduce the likelihood of the recurrence of earlier problems. A short analysis of the root causes of these problems is presented

  13. Structural load inventory database for the Kansas City Plant

    International Nuclear Information System (INIS)

    A structural load inventory database (LID) has been developed to support configuration management at the DOE Kansas City Plant (KCP). The objective of the LID is to record loads supported by the plant structures and to provide rapid assessments of the impact of future facility modifications on structural adequacy. Development of the LID was initiated for the KCP's Main Manufacturing Building. Field walkdowns were performed to determine all significant loads supported by the structure, including the weight of piping, service equipment, etc. These loads were compiled in the LID. Structural analyses for natural phenomena hazards were performed in accordance with UCRL-15910. Software to calculate demands on the structural members due to gravity loads, total demands including both gravity and seismic loads, and structural member demand-to-capacity ratios were also developed and integrated into the LID. Operation of the LID is menu-driven. The LID user has options to review and print existing loads and corresponding demand-to-capacity ratios, and to update the supported loads and demand-to-capacity ratios for any future facility modifications

    2015-06-01

    Currently, the need for mobility can cause significant pollution levels in cities, with important effects on health and quality of life. Any approach to the study of urban pollution and its effects requires an analysis of spatial distribution and temporal variability. It is a crucial dilemma to obtain proven methodologies that allow an increase in the quality of the prediction and the saving of resources in the spatial and temporal sampling. This work proposes a new analytical methodology in the study of temporal structure. As a result, a model for estimating annual levels of urban traffic noise was proposed. The average errors are less than one decibel in all acoustics indicators. A new working methodology of urban noise has begun. Additionally, a general application can be found for the study of the impacts of pollution associated with traffic, with implications for urban design and possibly in economic and sociological aspects.

    Nowadays the fast economic development has brought about serious conflicts between the limited land resources and the increasing land demand in Chuzhou City.The changes of land use structure also restrict economic development and society progress in this area.Because different cities have different functional localization,the city area and each county (city) have formed characteristic land utilization structure.It is of great significance to make rational use of land resources and ensure the sustainable use of land resources by analyzing the variation of land use structure in the city area and each county (city) in Chuzhou City.Based on the data of land use modification of Chuzhou City from 1996 to 2005 and adopting the quantitative analysis of landscape ecology,this paper studies quantitatively the temporal division of regional land use structure and its dynamic changes.The results indicate that: (1) this method can reveal the law of the variation; (2) the variation of land use structure in Chuzhou City: increasing diversification,evenness and heterogeneity; (3) the intensity of change in land use from 1996 to 2005 in the city appeared in the sequence: grass land>traffic land>garden land>virgin land>forest land>industrial and residential land>cultivated land>other agricultural land>water facility land; (4) there were remarkable differences between the city area and each county (city) in the relative change and the land use structure change from 1996 to 2005.This paper analyzes the variation of land use structure in Chuzhou City,and finally proposes related countermeasures and suggestions.

    The accurate prediction of the typhoon (hurricane) induced extreme sea environments is very important for the coastal structure design in areas influenced by typhoon (hurricane). In 2005 Hurricane Katrina brought a severe catastrophe in New Orleans by combined effects of hurricane induced extreme sea environments and upper flood of the Mississippi River. Like the New Orleans City, Shanghai is located at the estuarine area of the Changjiang River and the combined effect of typhoon induced extreme sea environments, flood peak runoff from the Changjiang River coupled with the spring tide is the dominate factor for disaster prevention design criteria. The Poisson-nested logistic trivariate compound extreme value distribution (PNLTCEVD) is a new type of joint probability model which is proposed by compounding a discrete distribution (typhoon occurring frequency) into a continuous multivariate joint distribution (typhoon induced extreme events). The new model gives more reasonable predicted results for New Orleans and Shanghai disaster prevention design criteria.

    In order to image the 3-D velocity structure of its shallow crust in Kunming region, China, finite-difference seismic tomography is used to invert the seismic data selected carefully from six-shot data. The result lays a foundation for the discussion of the relationship between the obtained velocity structure and the hidden faults, and for the illumination of the depth extents of main active faults surrounding Kunming city. Puduhe-Xishan fault lies on the western margin of the Kunming basin and is just situated on the west edge of the low velocity anomaly zone found at all depth levels. This indicates that this fault is a borderline fault of the Kunming basin. It can be concluded that the fault dips eastwards with a steep angle and its depth extent is large. Puji-Hanjiacun fault and Heilongtan-Guandu fault play a role in controlling the low velocity anomaly zone in middle basin. The depth extents of the two faults are comparatively small, without traversing the interface of basin floor.

    Full Text Available Abstract Background Protein structural alignment provides a fundamental basis for deriving principles of functional and evolutionary relationships. It is routinely used for structural classification and functional characterization of proteins and for the construction of sequence alignment benchmarks. However, the available techniques do not fully consider the implications of protein structural diversity and typically generate a single alignment between sequences. Results We have taken alternative protein crystal structures and generated simulation snapshots to explicitly investigate the impact of structural changes on the alignments. We show that structural diversity has a significant effect on structural alignment. Moreover, we observe alignment inconsistencies even for modest spatial divergence, implying that the biological interpretation of alignments is less straightforward than commonly assumed. A salient example is the GroES 'mobile loop' where sub-Ångstrom variations give rise to contradictory sequence alignments. Conclusion A comprehensive treatment of ambiguous alignment regions is crucial for further development of structural alignment applications and for the representation of alignments in general. For this purpose we have developed an on-line database containing our data and new ways of visualizing alignment inconsistencies, which can be found at http://www.ibi.vu.nl/databases/stralivari.

  1. Lessons Learned from Recent Failure and Incident Investigations of Composite Structures

    2008-01-01

    During the past few decades, NASA Langley Research Center (LaRC) has supported several large-scale failure and incident investigations and numerous requests for engineering consultations. Although various extenuating circumstances contributed to each of these incidents, in all cases, the failure resulted from accumulation and/or propagation of damage that reduced the load carrying capability of the structure to a level below that which was needed to sustain structural loads. A brief overview of various failure and incident investigations supported by LaRC, including some of the computational and experimental methodologies that have been applied, is presented. An important outcome of many of these failure and incident investigations is the development of an improved understanding of not only the state-of-the-art in experimental and analytical methods but also the state-of-the-art in the design and manufacturing processes that may contribute to such failures. In order to provide insight into such large-scale investigations, a series of lessons learned were captured. Awareness of these lessons learned is highly beneficial to engineers involved in similar investigations. Therefore, it is prudent that the lessons learned are disseminated such that they can be built upon in other investigations and in ensuing research and development activities.

    Abstract Background Fatal heroin overdose is a significant cause of mortality for injection drug users (IDUs). Many of these deaths are preventable because opiate overdoses can be quickly and safely reversed through the injection of Naloxone [brand name Narcan], a prescription drug used to revive persons who have overdosed on heroin or other opioids. Currently, in several cities in the United States, drug users are being trained in naloxone administration and given naloxone for immediate and ...

  7. Role of green structure and ecological services: a case study of bahawalpur city, pakistan

    International Nuclear Information System (INIS)

    Cities can make broader contribution to achieve the goals of sustainable development as they are considered major consumers of resources and ecological services. Ecological services provide a range of benefits at local, regional and global levels. Terrestrial ecosystem has different components in urban environment that provides ecological services to its inhabitants. Cities not only benefit from the internal urban ecosystem but also depend upon other ecosystems beyond the city limit. Green structure is an important component in terms of making city more sustainable and habitable. Green structure in urban environment means green infrastructure that is planned and supports sustainable that is planned and supports sustainable urban development. From planning perspective, spatial structure of green space provides a basis for sustainable urban development. In sustainable perspective, green structure more than the sum of green spaces. It is considered as spatial network of open spaces, public and private gardens and parks, sports fields, allotment gardens, woodlands and recreational grounds. Therefore, it is considered as a significant part of built-up environment and major source of ecological services. To structure urban areas of sustainable development, it is necessary to develop a proportion between grey and green cities. Keeping in view, research has been conducted to investigate spatial network of green structure in planned areas of Bahawalpur City of Pakistan. This study analyzes the ecological services generated from the investigated green structures, and helped develop an approach of inter-relation between green environment and urban society. Moreover, strategies for better land-use planning in green and sustainable perspective have been proposed. (author)

  8. NDT with the structural weld overlay program. Recent field experience and lessons learned

    International Nuclear Information System (INIS)

    Structural weld overlay (SWOL) has become a predominant mitigation technique within the Alloy 600 program. For the pressurizer nozzles, MRP-139 requires volumetric examination by year end 2007. Many nozzles are un-inspectable due to geometry and material limitations that preclude interrogation of the required examination volume. SWOL therefore is the mitigation technique which overcomes these limitations. SWOL of the pressurizer nozzles has been a challenge for all the vendors. Alloy 52 has proven to be difficult to weld under field conditions. The NDT technique chosen to demonstrate the integrity of the overlay needs to be adapted to the specific repair process and nozzle geometry. The purpose of this paper will be to present Westinghouse's integrated approach for SWOL with the focus on the NDT aspects. Topics will include main repair process steps, NDT qualification, recent field experience and lessons learned. (author)

    2014-09-01

    Full Text Available Structures designed in accordance with even the most modern buildings codes are expected to sustain damage during a severe earthquake; however; these structures are expected to protect the lives of the occupants. Damage to the structure can require expensive repairs; significant business downtime; and in some cases building demolition. If damage occurs to many structures within a city or region; the regional and national economy may be severely disrupted. To address these shortcomings with current seismic lateral force resisting systems and to work towards more resilient; sustainable cities; a new class of seismic lateral force resisting systems that sustains little or no damage under severe earthquakes has been developed. These new seismic lateral force resisting systems reduce or prevent structural damage to nonreplaceable structural elements by softening the structural response elastically through gap opening mechanisms. To dissipate seismic energy; friction elements or replaceable yielding energy dissipation elements are also included. Post-tensioning is often used as a part of these systems to return the structure to a plumb; upright position (self-center after the earthquake has passed. This paper summarizes the state-of-the art for self-centering seismic lateral force resisting systems and outlines current research challenges for these systems.

  13. Modeling Fractal Structure of Systems of Cities Using Spatial Correlation Function

    CERN Document Server

    Chen, Yanguang

    2016-01-01

    This paper proposes a new method to analyze the spatial structure of urban systems using ideas from fractals. Regarding a system of cities as a set of "particles" distributed randomly on a triangular lattice, we construct a spatial correlation function of cities. Suppose that the spatial correlation follows the power law. It can be proved that the correlation exponent is the second order generalized dimension. The spatial correlation model is applied to the system of cities in China. The results show that the Chinese urban system can be described by the correlation dimension ranging from 1.3 to 1.6. The fractality of self-organized network of cities in both the conventional geographic space and the "time" space is revealed with the empirical evidence. The spatial correlation analysis is significant in that it is applicable to both large and small sizes of samples and can be used to link different fractal dimensions in urban study, including box dimension and radial dimension.

    2008-01-01

    Cities separated in space are connected together by spatial interaction (SI) between them.But the studies focusing on the SI are relatively few in China mainly because of the scarcity of data.This paper deals with the SI in terms of rail passenger flows,which is an important aspect of the network structure of urban agglomeration.By using a data set consisting of rail O-D (origin-destination) passenger flows among nearly 200 cities,inter-city rail distance O-D matrixes,and some other indices,it is found that the attenuating tendency of rail passenger is obvious.And by the analysis on dominant flows and spatial structure of flows,we find that passenger flows have a trend of polarizing to hubs while the linkages between hubs upgrade.However,the gravity model reveals an overall picture of convergence process over time which is not in our expectation of integration process in the fiamework of globalization and economic integration.Some driven factors for the re-organization process of the structure of urban agglomeration,such as technique advance,glohalization,etc.are discussed further based on the results we obtained.

    2003-01-01

    The growing attention on urban tourism was very widespread. There are two angles to study urban tourism: supply-side and demand-side. And the supply-side of the tourism remains very important. The RBD (Recreation Business District) is a useful framework to understand the components of urban tourism and how they fit together. The paper begins with a review on the RBD and the spatial structure of tourism in urban areas and then attempts to develop a more general understanding of the spatial structure evolution of RBDs in a tourist-historic citySuzhou. The spatial structures and functions of the RBDs in Suzhou are examined, based on field observations, interviews with city officials and industry leaders, and a review of available documents. The urban tourism of Suzhou has developed in a range of contexts, that various types of RBDs have emerged as a result of different urban development strategies. The spatial structure has evolved from the past "Single-cored Structure" to "Double-cored Structure"at present, and then to "Chain Structure" in the future. The spatial form and evolution of RBD in Suzhou are closely relative with its urban spatial expansion. Urban area dispersal is the prerequisite of the emergence of the RBD. Planning and constructing the RBD becomes a new impetus to urban growth or renewal. Finally, a number of strategies for planning and developing the RBD in Suzhou are suggested. The different RBDs should adopt different strategies.Intensification can be the possible strategy for the RBDs in the ancient city. Accreting with the urban theme park or engrafting on the Jinji Lake is suggested respectively for the RBD in the Suzhou New District and the Suzhou Industrial Park.

  16. Head/tail Breaks for Visualization of City Structure and Dynamics

    CERN Document Server

    Jiang, Bin

    2015-01-01

    The things surrounding us vary dramatically, which implies that there are far more small things than large ones, e.g., far more small cities than large ones in the world. This dramatic variation is often referred to as fractal or scaling. To better reveal the fractal or scaling structure, a new classification scheme, namely head/tail breaks, has been developed to recursively derive different classes or hierarchical levels. The head/tail breaks works as such: divide things into a few large ones in the head (those above the average) and many small ones (those below the average) in the tail, and recursively continue the dividing process for the large ones (or the head) until the notion of far more small things than large ones has been violated. This paper attempts to argue that head/tail breaks can be a powerful visualization tool for illustrating structure and dynamics of natural cities. Natural cities refer to naturally or objectively defined human settlements based on a meaningful cutoff averaged from a massi...

    Detecting regional spatial structures based on spatial interactions is crucial in applications ranging from urban planning to traffic control. In the big data era, various movement trajectories are available for studying spatial structures. This research uses large scale Shanghai taxi trip data extracted from GPS-enabled taxi trajectories to reveal traffic flow patterns and urban structure of the city. Using the network science methods, 15 temporally stable regions reflecting the scope of people's daily travels are found using community detection method on the network built from short trips, which represent residents' daily intra-urban travels and exhibit a clear pattern. In each region, taxi traffic flows are dominated by a few 'hubs' and 'hubs' in suburbs impact more trips than 'hubs' in urban areas. Land use conditions in urban regions are different from those in suburban areas. Additionally, 'hubs' in urban area associate with office buildings and commercial areas more, whereas residential land use is mor...

    2009-01-01

    Full Text Available This study analysis the spatial pattern change with regards to landscape connectivity in Aydin by using landscape structure indices and GIS technology. Rectified black and white aerial protographs from 1977 and pan sharpened Ikonos images from 2002 are used in the analysis. A set of class level landscape structure indices are employed: percentage of landscape; patch number; mean patch size; area weighted mean patch size; mean shape index and connectance index. The findings indicate a decrease in the proportion, patch number, mean patch size and connectance of the crop fields, fruit groves and natural areas and an increase of these attributes for open spaces, vacant lots and urban built up areas. The recommendations to improve the spatial structure in relation to landscape connectivity include: increasing the amount of natural patches by restoring the natural attributes of the open space patches; mitigating the conversion of open spaces to urban built up areas by allocating suitable areas as parks and open space corridors for a city wide ecological network; making agricultural patches as main components of the local and regional ecological networks; encouraging ecologically sound agricultural practices for an effective network structure; preserving riparian corridors and improving structure by applying ecologically sound design principles and encouraging finger-like development pattern to implement green wedges penetrating into the urban core areas.

  2. A socio-structural analysis of crime in the city of Tshwane, South Africa

    Directory of Open Access Journals (Sweden)

    Gregory D. Breetzke

    2010-10-01

    Full Text Available High and rising levels of crime plague post-apartheid South Africa. A common explanation for these high crime rates relates the country’s unique socio-political past to a system of ineffective social control mechanisms that suggest high levels of social disorganisation within certain communities. Other explanations emphasise the presence of disaffected youths and deprivation, as well as the rapid immigration of people from neighbouring African countries into South Africa. I examined a number of these socio-structural explanations of crime on contact crime rates in the city of Tshwane, South Africa. The findings are largely consistent with the social disorganisation theory, as well as with what has previously been suggested in local literature. In order to supplement these preliminary findings, the effects of the same socio-structural explanations on contact crime rates were determined for predominantly Black, White, and ‘Mixed’ (containing a mix of both Black and White residents suburbs using spatial regression models. Evidence from these analyses suggests that the effects of the various socio-structural explanations do not appear to traverse racial lines. Rather, the findings suggest non-uniformity in terms of the extent to which the various socio-structural factors impact contact crime rates based on race.

  3. Modeling the self-affine structure and optimization conditions of city systems using the idea from fractals

    International Nuclear Information System (INIS)

    This paper demonstrates self-affine fractal structure of city systems by means of theoretical and empirical analyses. A Cobb-Douglas-type function (C-D function) of city systems is derived from a general urban response equation, and the partial scaling exponent of the C-D function proved to be the fractal dimension reflecting the self-affine features of city systems. As a case, the self-affine fractal model is applied to the city of Zhengzhou, China, and the result is satisfying. A fractal parameter equation indicative of structural optimization conditions is then obtained from the C-D function. The equation suggests that priority should be given to the development of the urban element with a lower fractal dimension, or a higher partial scaling exponent, for utility maximization. Moreover, the fractal dimensions of different urban elements tend to become equivalent to each other in the long term. Accordingly, it is self-similar fractals rather than self-affine fractals that represent the optimal structure of city systems under ideal conditions.

  4. When the levee breaks - public policy and holistic risk management - lessons from Katrina for coastal cities faced with rising storm surge flood risk

    Science.gov (United States)

    Muir-Wood, R.

    2009-04-01

    In a period of accelerating sea level rise and increased tropical cyclone intensities, extreme 100 year coastal flood levels are rising rapidly along a number of tropical and subtropical coastlines. Meanwhile, whether from natural megadelta consolidation, post glacial rebound or overpumping of shallow aquifers, many coastal cities are sinking even faster than mean sea level is rising. Without significant investment in continually improved flood defence inevitably this means the risk of catastrophic flooding is rising, for many cities quite steeply. The experience of Hurricane Katrina and New Orleans may become seen as iconic for 21st Century catastrophe risk as more and more coastal cities are subject to similar calamities. The story of New Orleans also highlights many aspects of catastrophe risk management failures before and after extreme events. The city of New Orleans had already been flooded three times by storm surges in the 100 years before Katrina. After each flood, investments were made in improved flood defences but these investments dwindled through time as there appeared to be a reduced imperative to divert money to support abstract risk reduction. Meanwhile land subsidence and rising sea levels and storm surges meant that risk levels continued to rise, until the inevitable time when the city once again was flooded. As the city increasingly sinks below mean sea level the impact of each flood has become increasingly catastrophic, both in terms of areas flooded, property damage and casualties. While a major program of investment in improved flood defences has once again followed the catastrophic 2005 flood, Federal government agencies have given no assurance that levels of flood risk will be maintained below some designated threshold long term. Therefore another cycle of rising flood risk has now started that will inevitably eventually to lead to the city becoming reflooded. This cycle can only end with the eventual abandonment of much of the city area

    In recent times, the domain of network science has become extremely useful in understanding the underlying structure of various real-world networks and to answer non-trivial questions regarding them. In this study, we rigourously analyze the statistical properties of the bus networks of six major Indian cities as graphs in L- and P-space, using tools from network science. Although public transport networks, such as airline and railway networks have been extensively studied, a comprehensive study on the structure and growth of bus networks is lacking. In India, where bus networks play an important role in day-to-day commutation, it is of significant interest to analyze their topological structure, and answer some of the basic questions on their evolution, growth, robustness and resiliency. We start from an empirical analysis of these networks, and determine their principle characteristics in terms of the complex network theory.

  6. Urban scaling and its deviations: revealing the structure of wealth, innovation and crime across cities.

    Directory of Open Access Journals (Sweden)

    Luís M A Bettencourt

    Full Text Available With urban population increasing dramatically worldwide, cities are playing an increasingly critical role in human societies and the sustainability of the planet. An obstacle to effective policy is the lack of meaningful urban metrics based on a quantitative understanding of cities. Typically, linear per capita indicators are used to characterize and rank cities. However, these implicitly ignore the fundamental role of nonlinear agglomeration integral to the life history of cities. As such, per capita indicators conflate general nonlinear effects, common to all cities, with local dynamics, specific to each city, failing to provide direct measures of the impact of local events and policy. Agglomeration nonlinearities are explicitly manifested by the superlinear power law scaling of most urban socioeconomic indicators with population size, all with similar exponents (1.15. As a result larger cities are disproportionally the centers of innovation, wealth and crime, all to approximately the same degree. We use these general urban laws to develop new urban metrics that disentangle dynamics at different scales and provide true measures of local urban performance. New rankings of cities and a novel and simpler perspective on urban systems emerge. We find that local urban dynamics display long-term memory, so cities under or outperforming their size expectation maintain such (disadvantage for decades. Spatiotemporal correlation analyses reveal a novel functional taxonomy of U.S. metropolitan areas that is generally not organized geographically but based instead on common local economic models, innovation strategies and patterns of crime.

  7. The Structural Transformation of the Labor Markets in China' s Large Cities

    2011-01-01

    By means of the data, on the employment in Shanghai in 2003 and 2009, gathered by our investigations, we have, in this paper, made a case study on the structural transformation of the labor markets in large cities. Through the comparison between the people with the registered permanent residence in Shanghai and the people from without (TPFW) in the aspects of the section in which they are employed, of the degree and kind of job flow, of the return rate in educa- tion, of the impact of the job flow on their income, we have discovered some new significant facts, mainly including the rise of the rate of TPFW who work in regular departments, the increase in the educational return for TPFW, the tendency to the equality in the educational return between TPFW and the people with the resisted permanent residence in Shanghai Therefore, we have made the deduction that, according to the relationship between the income and the hu- man capital, the structural transformation from the dual splitting to the integration has been basically completed in the labor market in Shanghai. At present, there are some differences between TPFW and the people with the registered permanent residence in Shanghai in income and professional distribution and other aspects, mainly because of the gap in human resources and other factors, and the institutional discrimination against TPFW in the selection of jobs and the social security and other respects.

    In order to image the 3-D velocity structure of its shallow crust in Ktmming region, China, finite-difference seismic tomography is used to invert the seismic data selected carefully from six-shot data. The result lays a founda-tion for the discussion of the relationship between the obtained velocity structure and the hidden faults, and for the illumination of the depth extents of main active faults surrounding Kunming city. Puduhe-Xishan fault lies on the western margin of the Kunming basin and is just situated on the west edge of the low velocity anomaly zone found at all depth levels. This indicates that this fault is a borderline fault of the Kunming basin. It can be concluded that the fault dips eastwards with a steep angle and its depth extent is large. Puji-Hanjiacun fault and Heilong-tan-Guandu fault play a role in controlling the low velocity anomaly zone in middle basin. The depth extents of the two faults arc comparatively small, without traversing the interface of basin floor.

    The spatial structure and multi-scale feature of the atmospheric pollution influence domain of Beijing and its peripheral areas (a rapidly developed city agglomeration) is dissected and analyzed in this paper on the basis of the atmospheric pollution dynamic-chemical process observation data of the urban building ensemble boundary layer of the Beijing City Air Pollution Observation Experiment (BECAPEX) in winter (February) and summer (August) 2003, and relevant meteorological elements and satellite retrieval aerosol optical depth (AOD), etc. comprehensive data with the dynamic-statistical integrated analysis of "point-surface" spatial structure. Results show that there existed significant difference in the contribution of winter/summer different pollution emission sources to the component character of atmospheric pollution, and the principal component analysis (PCA) results of statistical model also indicate that SO2 and NOX dominated in the component structure of winter aerosol particle; instead, CO and NOX dominated in summer. Surface layer atmospheric dynamic and thermal structures and various pollutant species at the upper boundary of building ensembles at urban different observational sites of Beijing in winter and summer showed an "in-phase" variation and its spatial scale feature of "influence domain". The power spectrum analysis (PSA) shows that the period spectrum of winter/summer particle concentration accorded with those of atmospheric wind field: the longer period was dominative in winter, but the shorter period in summer, revealing the impact of the seasonal scale feature of winter/summer atmospheric general circulation on the period of atmospheric pollution variations. It is found that from analyzing urban area thermal heterogeneity that the multiscale effect of Beijing region urban heat island (UHI) was associated with the heterogeneous expansion of tall buildings area. In urban atmospheric dynamical and thermal characteristic spatial structures, the

    A study of past composite aircraft structures programs was conducted to determine the lessons learned during the programs. The study focused on finding major underlying principles and practices that experience showed have significant effects on the development process and should be recognized and understood by those responsible for using of composites. Published information on programs was reviewed and interviews were conducted with personnel associated with current and past major development programs. In all, interviews were conducted with about 56 people representing 32 organizations. Most of the people interviewed have been involved in the engineering and manufacturing development of composites for the past 20 to 25 years. Although composites technology has made great advances over the past 30 years, the effective application of composites to aircraft is still a complex problem that requires experienced personnel with special knowledge. All disciplines involved in the development process must work together in real time to minimize risk and assure total product quality and performance at acceptable costs. The most successful programs have made effective use of integrated, collocated, concurrent engineering teams, and most often used well-planned, systematic development efforts wherein the design and manufacturing processes are validated in a step-by-step or 'building block' approach. Such approaches reduce program risk and are cost effective.

  1. Classification of the treble clef zinc finger: noteworthy lessons for structure and function evolution.

    Science.gov (United States)

    Kaur, Gurmeet; Subramanian, Srikrishna

    2016-01-01

    Treble clef (TC) zinc fingers constitute a large fold-group of structural zinc-binding protein domains that mediate numerous cellular functions. We have analysed the sequence, structure, and function relationships among all TCs in the Protein Data Bank. This led to the identification of novel TCs, such as lsr2, YggX and TFIIIC τ 60 kDa subunit, and prediction of a nuclease-like function for the DUF1364 family. The structural malleability of TCs is evident from the many examples with variations to the core structural elements of the fold. We observe domains wherein the structural core of the TC fold is circularly permuted, and also some examples where the overall fold resembles both the TC motif and another unrelated fold. All extant TC families do not share a monophyletic origin, as several TC proteins are known to have been present in the last universal common ancestor and the last eukaryotic common ancestor. We identify several TCs where the zinc-chelating site and residues are not merely responsible for structure stabilization but also perform other functions, such as being redox active in C1B domain of protein kinase C, a nucleophilic acceptor in Ada and catalytic in organomercurial lyase, MerB.

  8. Lessons learned from full-scale vibration tests on nuclear power plant auxiliary structure in Switzerland

    International Nuclear Information System (INIS)

    The Beznau Nuclear Power Plant is located in northern Switzerland. The plant is owned and operated by the Nordostschweizerische Kraftwerke AG (NOK) in Baden, Switzerland. It is a twin unit plant (2 x 350 MWe) which was designed in the early 1960's and placed into commercial operation between 1969 and 1971. In connection with a major backfit project, which will improve the safety of the plant against external events, the free-standing boric water tanks had to be relocated and were replaced by two boric water tanks in a new building (the so called BOTA-building). It enabled to plan and perform full scale vibration tests.The scope of experimental investigation was to determine the eigenfrequencies and damping values for fundamental soil-structure interaction. The vibration tests allowed identification of the important modes of the soil-structure system in the range 3 to 15 Hz. The excitation was strung enough to generate accelerations in the structure comparable to those of a small earthquake. From the comparisons of computed and measured results it is concluded that the rocking frequency can be reasonably well predicted by either Finite Element or Lumped Parameter models with springs simulating the soil-foundation stiffness, provided in the case of the latter the embedment is taken into account. The prediction of the amplitude of structural response appears to be more difficult, as shown by the differences in the mode shapes. In the frequency range 8 to 10 Hz the agreement between computed and test results was less satisfactory. The actual structural behaviour turned out to be more complex than expected and needs further investigation with the aid of more refined models for the soil-structure system

    Pfingsten, Jennifer S; Kieft, Jeffrey S

    2008-07-01

    In eukaryotes, the canonical process of initiating protein synthesis on an mRNA depends on many large protein factors and the modified nucleotide cap on the 5' end of the mRNA. However, certain RNA sequences can bypass the need for these proteins and cap, using an RNA structure-based mechanism called internal initiation of translation. These RNAs are called internal ribosome entry sites (IRESes), and the cap-independent initiation pathway they support is critical for successful infection by many viruses of medical and economic importance. In this review, we briefly describe and compare mechanistic and structural groups of viral IRES RNAs, focusing on those IRESes that are capable of direct ribosome recruitment using specific RNA structures. We then discuss in greater detail some recent advances in our understanding of the intergenic region IRESes of the Dicistroviridae, which use the most streamlined ribosome-recruitment mechanism yet discovered. By combining these findings with knowledge of canonical translation and the behavior of other IRESes, mechanistic models of this RNA structure-based process are emerging. PMID:18515544

    Disaster management of a city, in coherent, stable and true manner, were realized by understanding and organizing of the disaster plan. When we consider the earthquake hazard of Marmara Region, it was investigated by the scientific studies how -a world city- Istanbul were effected this earthquake. When we consider the scientific data and we take a base the current legal structure of our country, the aim of the disaster plan is to provide the fist and emergency aid for the citizens when the destructive earthquake were occurred and effected the general life. This disaster plan includes base of the coordination and helping each other of the activity which all institution and organizations will do during possible disaster. The aims of making of plan is to provide the cooperation and collaboration between before the disaster and to act urgently during the disaster, and to provide the following necessary activity. This necessary activity as main headlines are; the providing of communication and transportation; regulation of traffic; rescue; emergency medical aid, to transportation patient and injured people to the hospitals; to put out fire; to provide security and public order; eating, dressing, heating and lighting studies; to provide temporary housing; the burial of dead citizens; to remove wreckage; to repair and to re-provide the electrical, water and canalization construction. In this study, it will mainly be presented Istanbul city disaster plan. Disaster plan of this city were produced by the intensive and sacrificial efforts with Turkish legal system. After that, disaster plan must updated as soon as possible. However government must regulate current legal system ( or the body of current law) related disaster plan. City disaster plan, which even construct well, include only the operations after the disaster. Before disaster, methods of preventive precaution against the disaster must add the plan with applicable legal system

    Zipf's law is one the most conspicuous empirical facts for cities, however, there is no convincing explanation for the scaling relation between rank and size and its scaling exponent. Based on the idea from general fractals and scaling, this paper proposes a dual competition hypothesis of city develop to explain the value intervals and the special value, 1, of the power exponent. Zipf's law and Pareto's law can be mathematically transformed into one another. Based on the Pareto distribution, a frequency correlation function can be constructed. By scaling analysis and multifractals spectrum, the parameter interval of Pareto exponent is derived as (0.5, 1]; Based on the Zipf distribution, a size correlation function can be built, and it is opposite to the first one. By the second correlation function and multifractals notion, the Pareto exponent interval is derived as [1, 2). Thus the process of urban evolution falls into two effects: one is Pareto effect indicating city number increase (external complexity), a...

  14. In pursuit of tax equity: lessons from VAT rate structure adjustment in Poland

    Directory of Open Access Journals (Sweden)

    Artur Świstak

    2015-06-01

    Full Text Available In 2011, in the aftermath of the economic crisis, Poland increased its value added tax rates. Despite an already large VAT policy gap, further rate differentiation was used to address distributional concerns and to protect the most vulnerable households. We find that the changes to the VAT rate structure hardly improved the overall progressivity of the VAT and the tax system as a whole. While providing only minimal relief to the poor, taxation of food products at a super reduced rate greatly subsidized the richer households. With a small change to the income tax structure, the government could have secured more progressivity at a lower cost in terms of revenue foregone.

    2010-05-01

    For the first time in history, the Global population is more urban than rural and the trend is obvious at various scales. Cities do not serve just as dynamic centres of activities, jobs and consumption markets, social interactions and cultural expressions, but also carry the weight of the main environmental problems of current times and the near future. Global Warming, air and water pollution, population growth and recourse constraints, i.e. reduction of carrying capacity of the environment are among the well known ones. The overall aim of this research is to develop mitigation (at various scales) and adaptation systems, tailored to urban settlements. They should be effective at the very local as well as regional levels, assess and introduce innovative urban technologies and policies, reduce ecological footprint of cities and increase recycling efficiency. We propose the empirical method of urban sustainability assessment, that supports our hypothesis that city functioning, the changes in its population and area growth depends on the size, average and internal densities and the geographical form. The existing cities of three regions are examined: Western and Eastern Europe (incl. Russia), Latin America and China. There are fundamental urban developmental differences and also within the first region, namely between EU countries and the Eastern part of European geographical region. The cities are considered not only as some agglomerates of areas with dense population but from the ecological point of view, namely examining inflow of food and energy and outflow of waste products across the boundaries. There are major differences between the patterns of urbanisation in the studied regions, urban systems functioning and resilience. Continuous investigation of these differenced helps building regional scenarios of cities development, population allocation and pollution management for the 21st century.

    This research initiative CITY 2020+ assesses the risks and opportunities for residents in urban built environments under projected demographic and climate change for the year 2020 and beyond, using the City of Aachen as a case study. CITY 2020+ develops scenarios, options and tools for planning and developing sustainable future city structures. We investigate how urban environment, political structure and residential behavior can best be adapted, with attention to the interactions among structural, political, and sociological configurations and with their consequences on human health. Demographers project that in the EU-25-States by 2050, approximately 30% of the population will be over age 65. Also by 2050, average tem¬peratures are projected to rise by 1 to 2 K. Combined, Europe can expect enhanced thermal stress and higher levels of particulate matter. CITY 2020+ amongst other sub-projects includes research project dealing with (1) a micro-scale assessment of blockages to low-level cold-air drainage flow into the city centre by vegetation and building structures, (2) a detailed analysis of the change of probability density functions related to the occurrence of heat waves during summer and the spatial and temporal structure of the urban heat island (UHI) (3) a meso-scale analysis of particulate matter (PM) concentrations depending on topography, local meteorological conditions and synoptic-scale weather patterns. First results will be presented specifically from sub-projects related to vegetation barriers within cold air drainage, the assessment of the UHI and the temporal and spatial pattern of PM loadings in the city centre. The analysis of the cold air drainage flow is investigated in two consecutive years with a clearing of vegetation stands in the beginning of the second year early in 2010. The spatial pattern of the UHI and its possible enhancement by climate change is addressed employing a unique setup using GPS devices and temperature probes fixed to

However, certain RNA sequences can bypass the need for these proteins and cap, using an RNA structure-based mechanism called internal initiation of translation. These RNAs are called internal ribosome entry sites (IRESes), and the cap-independent initiation pathway they support is critical for successful infection by m...

  20. Designing, implementing and monitoring social impact mitigation strategies: Lessons from Forest Industry Structural Adjustment Packages

    International Nuclear Information System (INIS)

    Social impact mitigation strategies are implemented by the proponents of policies and projects with the intent of reducing the negative, and increasing the positive social impacts of their activities, and facilitating the achievement of policy/project goals. Evaluation of mitigation strategies is critical to improving their future success and cost-effectiveness. This paper evaluates two Forest Industry Structural Adjustment Packages (FISAP) implemented in Australia in the 1990s to 2000s as part of broader policy changes that reduced access to timber from publicly owned native forests. It assesses the effectiveness of the structure, design, implementation and monitoring of the FISAPs, and highlights the interactions between these four elements and their influence on social impacts. The two FISAPs were found to be effective in terms of reducing negative impacts, encouraging positive impacts and contributing towards policy goals, although they did not mitigate negative impacts in all cases, and sometimes interacted with external factors and additional policy changes to contribute to significant short and long term negative impacts. -- Highlights: ► Mitigation strategies aim to reduce negative and enhance positive social impacts ► Mitigation strategy design, implementation, and monitoring are critical to success ► Effective mitigation enhanced the capacity of recipients to respond to change ► Mitigation strategies influenced multiple interacting positive and negative impacts ► Success required good communication, transparency, support, resources and timing

  1. Paradigms of structural safety of AGED plants. Lessons learned from Russian activities

    International Nuclear Information System (INIS)

    The study of the effects behind the degradation of components and material is becoming increasingly important for the safe operation of aged plants especially when it comes to life-extension. Since the Russian nuclear community began to examine life extension issues nearly fifteen years ago, there is much to learn from these Russian pioneering studies, a portion of which were performed under the TACIS (Technical Assistance for Commonwealth of Independent States) international collaboration program with EU countries. At the Ninth International Conference, recent data were introduced regarding the ageing effects of mechanical properties of various kinds of steel and the welding joints of Russian NPP components. The full title of the conference was Material Issues in Design, Manufacturing and Operation of Nuclear Power Plants Equipment. The meeting was organized by the Central Research Institute of Structural Materials (CRISM) 'Prometey' in cooperation with the IAEA and JRC-EU. In reviewing the recent data presented at the Ninth Conference, the authors think that the paradigms of structural integrity issues in aged plants are now reasonably well established in (1) fracture mechanics and irradiation hardening of reactor vessels and core internals and (2) thermal ageing and annealing effects. Yet even when considering these well established paradigms, the current direction of study is not adequately addressing the effects of a corrosive environment. The first author believes that the current approach of low cycle fatigue is far from able to prevent and predict environmentally assisted cracks. This fundamental flaw stems from design codes, which do not incorporate the basic knowledge of corrosion mechanisms. Our focus in researching aged plants should be re-directed toward environmentally assisted cracking, typically the film rupture-slip dissolution mechanism of crack propagation under the effect of long cell action on local cells, as discussed by the first author in

    Sulfated polysaccharide was extracted from the internal shell (gladius) of Sepioteuthis lessoniana. The sulfated polysaccharide contained 61.3% of carbohydrate, 0.8% of protein, 28.2% of ash and 1.33% of moisture respectively. The elemental composition was analyzed using CHNS/O analyzer. The molecular weight of sulfated polysaccharide determined through PAGE was found to be as 66kDa. Monosaccharides analysis revealed that sulfated polysaccharide was composed of rhamnose, galactose, xylose and glucose. The structural features of sulfated polysaccharide were analyzed by FT-IR and NMR spectroscopy. Further the sulfated polysaccharide was evaluated for its antibacterial activity against selected human clinical pathogens, namely Staphylococcus aureus, Klebsiella pneumoniae, Salmonella typhi, Vibrio cholerae, Klebsiella oxytoca, Escherichia coli, Salmonella paratyphi, Proteus mirabilis, Vibrio parahaemolyticus and Streptococcus pyogenes using agar well diffusion method. The polysaccharide has showed good antibacterial activity and MIC and MBC have also been evaluated. The anticancer activity was tested against HeLa cell line by MTT assay. The Cytotoxic Concentration (CC50) was observed as 700μg/ml and the maximum anticancer activity of 62.89% was recorded at 200μg/ml; whereas, the lowest of 9.87% was observed at 25μg/ml. In conclusion, the sulfated polysaccharide is an alternate, non-toxic and cheap source of substance that showed good antibacterial and anticancer acitivity. PMID:26724686

  3. Structuring learning environments: Lessons from the organization of post-literacy programs

    1989-12-01

    New conceptual and historical work on the nature of literacy and information on several bellwether post-literacy efforts in developing countries furnish a basis for diagnosing some of the deficiencies in current approaches to post-literacy programming. The key issue is the design of a `literate environment'. Heretofore attention has been concentrated too exclusively on the reading materials and continuing education side of the problem, and insufficient attention has been given to the more critical and difficult aspect: ensuring adequate opportunities for the application of new literate skills. The availability of these functional opportunities is closely related to the possibilities for accumulation and reinvestment of economic surplus in the environment, and to the way in which the related activities are organized. Literacy programs can unite skills relevant to management of local resources with strategies of cultural, political or religious revitalization that mobilize people to use their human resources. They therefore continue to offer an attractive means of initiating a reinvestment spiral from limited initial capital. To realize these potentials at the post-literacy stage, however, requires planning post-literacy before literacy, broadening programs to address primary school leavers as well, and paying greatly increased attention to the economic and social structure of the learning environment.

    2003-01-01

    Enterprise systems must have the structure to adapt the change of business environment. Whenrebuilding enterprise system to meet the extended operational boundaries, the concept of IT cityplanning is applicable and effective. The aim of this paper is to describe the architectural approachfrom the integrated information infrastructure (In3) standpoint and to propose for applying the "CityPlanning" concept for rebuilding "inter-application spaghetti" enterprise systems. This is mainlybecause the portion of infrastructure has increased with the change of information systems fromcentralized systems to distributed and open systems. As enterprise systems have involvedheterogeneity or architectural black box in them, it may be required the integration framework(meta-architecture) as a discipline based on heterogeneity that can provide comprehensive view of theenterprise systems. This paper proposes "EH Meta-model" as the integration framework that canoptimize the overall enterprise systems from the IT city planning point of view. EH Meta-modelconsists of "Integrated Information Infrastructure Map (In3-Map)", "Service Framework" and "ITScenario". It would be applicable and effective for the viable enterprise, because it has the mechanismto adapt the change. Finally, we illustrate a case of information system in an online securitiescompany and demonstrate applicability and effectiveness of EII Meta-model to meet their businessgoals.

    The water body of Taihu Lake has been eutrophicated because of area-source pollution. 83% of the total nitrogen and 84% of the total phosphorus of the pollutant that have washed into Taihu Lake originated from the fertilizer of crop land, rural animal husbandry and living sewage and rubbish in rural area. The goal of adjusting agricultural structure is to improve agricultural development, and to increase the peasants income by planting non-grain crop,centralizing animal husbandry, and intensifying aquaculture, etc, It is necessary to research on the influences of agriculture industrial structure on area-source pollution, This paper studies a case of Dapu Town in Yixing City, which is a typical drainage place beside Taihu Lake. On the basis of the analysis on the status quo of area-source pollution and agriculture industrial structure in Dapu Town, the conflicts between them are discussed. Non-grain crop production with a great deal of fertilizer and developing aquaculture with a great deal of organic pollutant, which are directly discharged,make area-source pollution more serious and accelerate the eutrophication in Taihu Lake. This paper suggests taking corresponding technological measures and policies, which have been tested in Dapu Town and demonstrated in Taihu Lake area.

    Historically, there is a tendency to focus on seismic structural performance of buildings, neglecting the potential for damage of non-structural elements. In particular, non-structural elements of buildings are their architectural parts (i.e. partitions, ceilings, cladding), electrical and mechanical components (i.e., distribution panels, piping, plumbing), and contents (e.g., furniture, bookcases, computers and desktop equipment). Damage of these elements often contributes significantly to earthquake impacts. In the 1999 Izmit Earthquake, Turkey, 50% of the injuries and 3% of human losses were caused by non-structural failures. In the 2010-2011 Christchurch Earthquakes (New Zealand), 40% of building damage was induced by non-structural malfunctions. Around 70%-85% of construction cost goes into these elements, and their damage can strongly influence the ability of communities to cope with and recover from earthquakes. The project Know your city, Reduce seISmic risK through non-structural elements (KnowRISK) aims at facilitating local communities' access to expert knowledge on non-structural seismic protection solutions. The project will study seismic scenarios critical for non-structural damage, produce a portfolio of non-structural protection measures and investigate the level of awareness in specific communities. We will implement risk communication strategies that will take into account the social and cultural background and a participatory approach to raise awareness in local communities. The paradox between the progress of scientific knowledge and the ongoing increase of losses from natural disasters worldwide is a well-identified gap in the UN Hyogo Framework for Action 2005-2015, in which one of the main priorities is the investment on "knowledge use, innovation and education to build a culture of safety and resilience". The KnowRISK is well aligned with these priorities and will contribute to participatory action aimed at: i) transferring expert knowledge

    Bonanza-grade orebodies in epithermal-style mineral deposits characteristically occur as discrete zones within spatially more extensive fault and/or fracture systems. Empirically, the segregation of such systems into compartments of higher and lower permeability appears to be a key process necessary for high-grade ore formation and, most commonly, it is such concentrations of metals that make an epithermal vein district world class. In the world-class silver- and gold-producing Comstock mining district, Nevada, several lines of evidence lead to the conclusion that the Comstock lode is localized in an extensional stepover between right-lateral fault zones. This evidence includes fault geometries, kinematic indicators of slip, the hydraulic connectivity of faults as demonstrated by veins and dikes along faults, and the opening of a normal-fault-bounded, asymmetric basin between two parallel and overlapping northwest-striking, lateral- to lateral-oblique-slip fault zones. During basin opening, thick, generally subeconomic, banded quartz-adularia veins were deposited in the normal fault zone, the Comstock fault, and along one of the bounding lateral fault zones, the Silver City fault. As deformation continued, the intrusion of dikes and small plugs into the hanging wall of the Comstock fault zone may have impeded the ability of the stepover to accommodate displacement on the bounding strike-slip faults through extension within the stepover. A transient period of transpressional deformation of the Comstock fault zone ensued, and the early-stage veins were deformed through boudinaging and hydraulic fragmentation, fault-motion inversion, and high- and low-angle axial rotations of segments of the fault planes and some fault-bounded wedges. This deformation led to the formation of spatially restricted compartments of high vertical permeability and hydraulic connectivity and low lateral hydraulic connectivity. Bonanza orebodies were formed in the compartmentalized zones of

Hypotheses: The study has the following hypotheses: 1. Leading the ball on various distances, and in different combinations of exercises, contributes to the improvement of the sixth grade pupils' technical skills. 2. The movement games under variated conditions contribute to the improvement of specific football skills in sixth grade pupils. MaterialThe experiment was conducted between February and April 2013 and consisted in applying a technical course to the sixth grade pupils from the "Mihail Sadoveanu" School in Bacau. For a better emphasis of the results, an initial and a final testing were done. The testing consisted in the subjects from the experimental and the witness group completing a technical course. The methods used in this research were: the observation, the experiment, the statistical-mathematical method. Results The analysis of the recorded data allows a few important observations at the end of the study: For the sixth graders, the initial tests were relatively similar, leading to ideas that are well-known by specialists in the field, that the general level of motor skills in middle school pupils is very low. Scoring goals being an action that involves a high degree of CNS decision making abilities, we can understand why puberty has this negative effect on the pupils' concentration and decision-making. Conclusions The novelty of introducing specific football means in the physical education lesson lead to an increase in the diversity of the used elements, which made me observe an improvement in the pupils' attention and involvement during classes. As means of the physical education, the game is of a real importance, due to its effects on the pupils' physical and intellectual development.

    Full Text Available Salvia japonica Thunb. (Japan: Aki-no-Tamurasou was a perennial herb, protandry insect-pollinated, and self-incompatible with water-flow dispersed seed. We used allozyme loci to know genetic structure of a S. japonica population. We examined spatial autocorrelation of individuals within five distance class with Moran`s I statistics. The area of observation was in plot 5x5 m2 in Botanical Garden of Osaka City University, Kisaichi, Katano, Osaka Prefecture. The 8 loci examined were polymorphic, namely Aat-1, Aat-2, Pgi, Mnr, Pgm-1, Pgm-2, Idh, and 6-Pgd. Low levels of genetic diversity were found for 29 individuals. Ninety-two percent cases for all of distance class were similar and only 8% (8 of 105 cases were significant differences. This result indicated that the spatial genetic distributions in all of distance classes were all similar and no spatial autocorrelation of genotypes. Only in distance class 2 had one significantly positive cases (0.15 in Pgm-1c, indicating that spatial genetic structure in the study population was weak at most. In the other word that spatial pattern of the individuals within S. japonica population was random. Overall of the result was indicating that genotype among individuals of S. japonica changed distantly and tended to isolation in distance by seed dispersed.

    Wake vortices are generated by airplanes in flight. These vortices decay slowly and may persist for several minutes after their creation. These vortices and associated smaller scale turbulent structures present a hazard to incoming flights. It is for this reason that incoming flights are timed to arrive after these vortices have dissipated. Local weather conditions, mainly prevailing winds, can affect the transport and evolution of these vortices; therefore, there is a need to fully understand localized wind patterns at the airport-sized mircoscale. Here we have undertaken a computational investigation into the impacts of localized wind flows and physical structures on the velocity field at Atlantic City International Airport. The simulations are undertaken in OpenFOAM, an open source computational fluid dynamics software package, using an optimized geometric mesh of the airport. Initial conditions for the simulations are based on historical data with the option to run simulations based on projected weather conditions imported from the Weather Research & Forcasting (WRF) Model. Sub-grid scale turbulence is modeled using a Large Eddy Simulation (LES) approach. The initial results gathered from the WRF Model simulations and historical weather data analysis are presented elsewhere.

    2011-02-01

    This paper presents the first paleostress results obtained from displacement and fracture systems within the Lower Eocene sediments at Jabal Hafit, Abu Dhabi Emirate, UAE. Detailed investigation of Paleogene structures at Jabal Hafit reveal the existence of both extensional structures (normal faults) and compressional structures (strike-slip and reverse faults). Structural analysis and paleostress reconstructions show that the Paleogene kinematic history is characterized by the succession of four paleostress stages. Orientation of principal stresses was found from fault-slip data using an improved right-dihedra method, followed by rotational optimisation (TENSOR program). The paleostress results confirm four transtensional tectonic stages (T1-T4) which affected the study area. The first tectonic stage (T1) is characterized by SHmax NW-SE σ2-orientation. This stage produced NW-SE striking joints (tension veins) and E-W to ENE-WSW striking dextral strike-slip faults. The proposed age of this stage is Early Eocene. The second stage (T2) had SHmax N-S σ2-orientation. N-S striking joints and NNE-SSW striking sinistral strike-slip faults, E-W striking reverse faults and N-S striking normal faults were created during this stage. The T2 stage is interpreted to be post-Early Eocene in age. The third stage (T3) is characterized by SHmax E-W σ2-orientation. This stage reactivated the E-W reverse faults as sinistral strike-slip faults and created E-W striking joints and NE-SW reverse faults. The proposed age for T3 is post-Middle Eocene. During the T3 ( SHmax E-W σ2-orientation) stage the NNW-plunging Hafit anticline was formed. The last tectonic stage that affected the study area (T4) is characterized by SHmax NE-SW σ2-orientation. During this stage, the ENE-WSW faults were reactivated as sinistral strike-slip and reverse faults. NE-SW oriented joints were also created during the T4 ( SHmax NE-SW σ2-orientation) stage. The interpreted age of this stage is post

    An advanced modeling technique, which allows us to compute realistic synthetic seismograms, is used to create a database of synthetic accelerograms in a set of selected sites located within Sofia urban area. The accelerograms can be used for the assessment of the local site response, represented in terms of Response Spectra Ratio (RSR). The result of this study, i.e. time histories, response spectra and other ground motion parameters, can be used for different earthquake engineering analyses. Finally, with the help of 3D finite elements modeling, the building structural performance is assessed

  12. Seismic isolation retrofitting of the Salt Lake City and County Building

    International Nuclear Information System (INIS)

    The City and County Building, a massive unreinforced masonry structure completed in 1894, has been seismically retrofitted using base isolation. The isolation system consists of 443 lead-rubber isolators installed underneath the building on top of existing spread footings. The building is isolated from the surrounding ground by a perimeter moat wall, permitting lateral movement to take place during an earthquake. It is believed that this is the first historic structure in the world to be retrofitted against possible seismic damage using base isolation. Lessons learned in this design effort are potentially applicable to seismic base isolation for nuclear power plants

  13. Structural classification of clay soils and its application in classifying Tehran City clays

    International Nuclear Information System (INIS)

    The behaviour of all reconstituted and natural clays is determined by their fabric and bonding. A new classification of clays is proposed in this paper on the basis of standard penetration test (Spt), the geological history and the one-dimensional compression of the clay in the 1v-σv plane. Although the eighth clay types defined in the classification have different origins, fabric and bonding, they all have either a syn-sedimentation or a post-sedimentation structure. The definition of these clay types is taken as a starting point for the construction of a general framework of behaviour of clays. In this research results of laboratory and field investigations of a very stiff Tehran silty clay in the natural and reconstituted states including Spt, Odometer, Scanning Electron Microscopy and polarizing microscopy are presented. The structure of the Tehran silty clay is strongly influenced by bonding, calcium carbonate content and weathering intensity. This soil is a very stiff to hard clay which geologically is over-consolidated. Consolidation curve of soils lies close to the Icl line. Hence the Tehran silty clay is a type 4 clay but, at certain depths where the yield stress ratio is greater than 1, the Tehran silty clay becomes a type 7 clay

    Female sex workers (FSWs) are disproportionately affected by both HIV and gender-based violence, such as that perpetrated by clients (CPV). We used a structural determinants framework to assess correlates of physical or sexual CPV in the past 6 months among FSWs in the Mexico/U.S. border cities of Ciudad Juárez and Tijuana. Bivariate and multivariate logistic regression analysis identified individual, client, interpersonal, work environment and macrostructural factors associated with recent CPV. Among 496 FSWs, 5 % experienced recent CPV. Witnessing violence towards other FSWs in one's neighborhood (aOR 5.6, 95 % CI 1.8-17.2), having a majority of foreign (aOR 3.5, 95 % CI 1.4-8.4) or substance using (aOR 4.0, 95 % CI 1.5-10.4) clients, and being a street worker (aOR 3.0, 95 % CI 1.1-7.7) were independently associated with recent CPV. Our findings underscore the vulnerability of FSWs and the need to design policies and interventions addressing macro-level influences on CPV rather than exclusively targeting individual behaviors.

    Public health HIV prevention efforts have begun to focus on addressing social and structural factors contributing to HIV risk, such as unstable housing, unemployment, and access to health care. With a limited body of evidence-based structural interventions for HIV, communities tasked with developing structural changes need a defined process to clarify their purpose and goals. This article describes the adaptations made to a coalition development model with the purpose of improving the start-up phase for a second group of coalitions. Modifications focused on preparing coalitions to more efficiently apply structural change concepts to their strategic planning activities, create more objectives that met study goals, and enhance coalition procedures such as building distributed coalition leadership to better support the mobilization process. We report on primary modifications to the process, findings for the coalitions, and recommendations for public health practitioners who are seeking to start a similar coalition. PMID:26785397

    2007-05-01

    Full Text Available This article is about the concept of the contemporary city - the influence that technology has when one thinks about, plans and lives in a city. The conjunction of technology and city reformulates customs and social practices; it can even determine the way one constitutes one's own identity. One can see how close the relation is between technology (specifically, TICS and the structures of the city in a wide variety of situations: in social interactions on the street, in transport, and in ways of buying, of working and entertainment. "@City" is a concept that very well reflects the emergent properties of a current city, that is, the coexistence of a physical and a virtual urban space. The "22@Barcelona" project attempts to bring together different types of spaces. By combining the physical with the virtual, 22@Barcelona, as a neighborhood of @City, creates an uncertain and blurred border between both spaces.The article also examines the impact that these spaces have on the psycho-social processes involved in the daily life of a traditionally working-class neighborhood, now strongly limited by technological boundaries.

    2015-11-01

    In many coastal and delta cities land subsidence now exceeds absolute sea level rise up to a factor of ten. A major cause for severe land subsidence is excessive groundwater extraction related to rapid urbanization and population growth. Without action, parts of Jakarta, Ho Chi Minh City, Bangkok and numerous other coastal cities will sink below sea level. Land subsidence increases flood vulnerability (frequency, inundation depth and duration of floods), with floods causing major economic damage and loss of lives. In addition, differential land movement causes significant economic losses in the form of structural damage and high maintenance costs for (infra)structure. The total damage worldwide is estimated at billions of dollars annually. As subsidence is often spatially variable and can be caused by multiple processes, an assessment of subsidence in delta cities needs to answer questions such as: what are the main causes? What is the current subsidence rate and what are future scenarios (and interaction with other major environmental issues)? Where are the vulnerable areas? What are the impacts and risks? How can adverse impacts be mitigated or compensated for? Who is involved and responsible to act? In this study a quick-assessment of subsidence is performed on the following mega-cities: Jakarta, Ho Chi Minh City, Dhaka, New Orleans and Bangkok. Results of these case studies will be presented and compared, and a (generic) approach how to deal with subsidence in current and future subsidence-prone areas is provided.

    Full Text Available In the quest for achieving sustainable cities, Intelligent and Knowledge City Programmes (ICPs and KCPs represent cost-efficient strategies for improving the overall performance of urban systems. However, even though nobody argues on the desirability of making cities “smarter”, the fundamental questions of how and to what extent can ICPs and KCPs contribute to the achievement of urban sustainability lack a precise answer. In the attempt of providing a structured answer to these interrogatives, this paper presents a methodology developed for investigating the modalities through which ICPs and KCPs contribute to the achievement or urban sustainability. Results suggest that ICPs and KCPs efficacy lies in supporting cities achieve a sustainable urban metabolism through optimization, innovation and behavior changes.

  18. Earthquakes in cities revisited

    CERN Document Server

    Wirgin, Armand

    2016-01-01

    During the last twenty years, a number of publications of theoretical-numerical nature have appeared which come to the apparently-reassuring conclusion that seismic motion on the ground in cities is smaller than what this motion would be in the absence of the buildings (but for the same underground and seismic load). Other than the fact that this finding tells nothing about the motion within the buildings, it must be confronted with the overwhelming empirical evidence (e.g, earthquakes in Sendai (2011), Kathmandu (2015), Tainan City (2016), etc.) that shaking within buildings of a city is often large enough to damage or even destroy these structures. I show, on several examples, that theory can be reconciled with empirical evidence, and suggest that the crucial subject of seismic response in cities is in need of more thorough research.

    2012-03-01

    Full Text Available Although studies have been done in China’s large cities on education policy issues, research is lacking on China’s smaller towns, which are more indicative of the situations throughout China. This article presents lessons learned from studying Chinese English teachers at four different schools that were adopting new English textbooks, in accordance with revised national education policy. Using conflict theory and social action theory as an analytical lens, and combining ethnographic and naturalistic inquiry as research methods, the article reports on the conflicts that the Chinese English teachers confronted as they were adopting the new English textbooks at the classroom level. Analysis of the implementation conflict resulted in lessons learned related to the influence of the traditional cultural and education structures, the impact of policy implementation contexts, and the availability of support systems for teachers. The lessons indicate that future education policymakers in both China and the United States need to be mindful of obstacles that teachers struggle to overcome when implementing new policies.

    2015-11-01

    To achieve the smart growth and equitable development in the region, urban planners should consider also lateral energies represented by the energy urban models like further proposed EEPGC focused on energy distribution via connections among micro-urban structures, their onsite renewable resources and the perception of micro-urban structures as decentralized energy carriers based on pre industrialized era. These structures are still variously bound when part of greater patterns. After the industrial revolution the main traded goods became energy in its various forms. The EEPGC is focused on sustainable energy transportation distances between the villages and the city, described by the virtual "energy circles". This more human scale urbanization, boost the economy in micro-urban areas, rising along with clean energy available in situ that surely gives a different perspective to human quality of life in contrast to overcrowded multicultural mega-urban structures facing generations of problems and struggling to survive as a whole.

    Full Text Available The new connections, which high speed train allows to activate among the metropolitan systems, seem to be able to give life to new urban macro-structures for which the transfer time, among the main poles of the railway segment, becomes comparable to an inside moving into the city and therefore considered as an inter-functional mobility. The tunnel effect generated by the high speed connection seems to be able to allow a new temporal and functional joint among the metropolitan systems consequently supporting the possibility, for the users, to move themselves among the different urban functions belonging to the different cities. The birth of these urban aggregations seems to drive towards new megalopolis, which we can define for the first time with the term: joint-city. For this new metropolitan settlement it seems to be very interesting to investigate the constitutive peculiarities, the systemic articulation, its relational structures, the evolutionary scenarios, and so on. The urban functions (activities can be considered as structures of relationships between people that allows to define "organizational links" inside the community; the urban functions are located in specific places inside urban container or in open spaces. The urban functions represent the urban engines and the functional system can be thought as the “soul of the city", abstract but essential to its survival. In the definition set out here the analysis is carried out for many interconnected urban functional system points (specifically those in Rome and Naples. The new high speed railway has to be considered not only as a new channel of mobility between cities, but as a real possibility of joint between the functional systems of the two centres. A final consideration can be carried out in relation to the possibility of implementing new measures of governance of urban transformations considering the new macro-city: the "Joint City".

  6. Computing the Image of the City

    CERN Document Server

    Jiang, Bin

    2012-01-01

    Kevin Lynch proposed a theory of the image of the city identifying five elements that make the city legible or imageable. The resulting mental map of the city was conventionally derived through some qualitative processes, relying on interactions with city residents to ask them to recall city elements from their minds. This paper proposes a process by which the image of the city can be quantitatively derived automatically using computer technology and geospatial databases of the city. This method is substantially based on and inspired by Christopher Alexander's living structure and Nikos Salingaros' structural order, as a city with the living structure or structural order tends to be legible and imageable. With the increasing availability of geographic information of urban environments at very fine scales or resolutions (for example, trajectories data about human activities), the proposal or solution described in this paper is particularly timely and relevant for urban studies and architectural design.

These factors have deconstructed the unified structure of cities and have caused spatial segregation of different parts of these settlements, especially central and old fabrics and finally resulted in their socio- economic segregation. On the other hand, external urban expansion led to a complicated physical and spatial structure, which is impossible to perceive its morphology in its totality. One of the theories and methods for exploring urban spatial structure is space syntax. Space syntax theory and technique is able to analyze urban spatial structure in relation to all spatial characteristic of the city. Also, the main purpose of this research is to answer this question that is there a meaningful relation between changes in value of spatial integration (resulting from space syntax analysis and changes in value of development quality (socio-economical, physical and environmental development of neighborhoods?2- Theoretical basesAccording to David Harvey's theories, there is a meaningful relation between socio-economic processes and the spatial form of a city; therefore, in order to comprehend socio-economic processes, understanding the spatial form of the city is essential. This theory also, believes that urban spaces are productions of social relationship and the connection between urban spaces follow social goals. Therefore, understanding the relation between urban spaces can help to perceive behavioral patterns and also quality and quantity analysis.Integration is the main concept of space syntax theory. This indicator is defined based on the connections and depth, not based on metric distance. Indeed, the integration degree of an urban area shows the integrity of that area with the entire city. Integration map of a city is an important tool in understanding the behavior of

    The BCR-ABL inhibitor imatinib has revolutionized the treatment of chronic myeloid leukemia. However, drug resistance caused by kinase domain mutations has necessitated the development of new mutation-resistant inhibitors, most recently against the T315I gatekeeper residue mutation. Ponatinib (AP24534) inhibits both native and mutant BCR-ABL, including T315I, acting as a pan-BCR-ABL inhibitor. Here, we undertook a combined crystallographic and structure-activity relationship analysis on ponatinib to understand this unique profile. While the ethynyl linker is a key inhibitor functionality that interacts with the gatekeeper, virtually all other components of ponatinib play an essential role in its T315I inhibitory activity. The extensive network of optimized molecular contacts found in the DFG-out binding mode leads to high potency and renders binding less susceptible to disruption by single point mutations. The inhibitory mechanism exemplified by ponatinib may have broad relevance to designing inhibitors against other kinases with mutated gatekeeper residues.

    Long, transparent tubular tilt-cages were developed to maintain experimental rats either in 45∘ head-up (orthostasis model), or in 45∘ head-down body position (antiorthostasis model) for several weeks. In order to study the functional and structural changes in extremity blood vessels, also novel pressure angiograph systems, as well as special quantitative electron microscopic methods were applied. It was found that several adaptive mechanisms are activated in the lower limb superficial veins and microvessels of muscles when an organism is exposed to long-term (1-2 weeks) orthostatic-type gravitational load including a reversible amplification of the pressure-dependent myogenic response, tuning of the myogenic tone by Ca++- and voltage-sensitive K+ channels in humans, augmentation of the intramural sympathetic innervation involving an increased nerve terminal density and synaptic vesicle count with functional remodeling, reorganization of vascular network properties (microvascular rarefaction in muscles, decreased branching angles in superficial veins), and responses of an endothelin and platelet-derived growth factor (PDGF) containing vesicle system in the endothelium. On the other hand, when applying long-term head-down tilting, the effects are dichotomous, e.g. it suppresses significantly the pressure-induced myogenic response, however does not diminish the adventitial sympathetic innervation density.

  15. Sustainable cities

    International Nuclear Information System (INIS)

    The Sustainable City Project, a collaboration among the cities of Portland, Oregon, and San Francisco and San Jose, California, aims at developing and implementing sustainable energy planning methods and programs for cites. For a period of two years (1989-90), the three project cities worked in parallel, yet pursued independent courses to develop appropriate sustainable urban energy practices to meet local needs and aspirations. Central to the Sustainable City Project was finding ways to manage today's urban energy needs without jeopardizing the needs of future generations. Sustainability implies that nothing should go to waste, but rather should contribute to the proper balance between the natural environment and the built environment Sustainable urban energy systems encompass more than energy efficiency and energy conservation measures: they must be diverse, flexible, self-reliant, renewable, and integrated. Since local governments make decisions affecting land use, building codes, transportation systems, waste disposal, and power plants--all of which impact energy resource use--local jurisdictions can do much to ensure their own sustainable future. This paper will present an accounting of the specific steps that each city took to determine and begin implementation of their respective approaches to sustainable energy planning, with a specific focus on the City of San Jose activities. Useful tools for facilitating community process, program planning and implementation, and quantitative analysis will also be discussed

The Shrinking Cities phenomenon has to be incorporated into the general assumptions about the...... contemporary city and maybe the understanding of the city needs to be updated in some areas, before we are able to do so. In this paper, the focus will be directed towards two themes which become present with the Shrinking Cities phenomenon and therefore seems important to discuss in order to understand the...... concept of Shrinking Cities. These two themes may affect the understanding of the existing city theory. The first theme is concerned with the physical understanding of the city where the traditional assumption about the city as a high density area, with buildings as the dominant structure, is questioned...

    We designed a 2-day inquiry activity where students learned about error analysis and coding practices in Python. Inquiry-based lessons provide students with opportunities to independently investigate scientific concepts and tools. A general structure is developed ahead of time and minimal, careful guidance provided during the activity, but students are given as much freedom as possible to explore the concepts at their own pace. We designed our activity to help students learn to write flexible, re-usable, and readable code. I will describe the lesson structure we initially designed, as well as what aspects worked for our students (or didn't) and our experience leading the activity.

    2011-01-01

    A strong urban heat island (UHI) appeared in a hot weather episode in Suzhou City during the period from 25 July to 1 August 2007. This paper analyzes the urban heat island characteristics of Suzhou City under this hot weather episode. Both meteorological station observations and MODIS satellite observations show a strong urban heat island in this area. The maximum UHI intensity in this hot weather episode is 2.2℃, which is much greater than the summer average of 1.0℃ in this year and the 37-year (from 1970 to 2006) average of 0.35℃. The Weather Research and Forecasting (WRF) model simulation results demonstrate that the rapid urbanization processes in this area will enhance the UHI in intensity, horizontal distribution, and vertical extension. The UHI spatial distribution expands as the urban size increases. The vertical extension of UHI in the afternoon increases about 50 m higher under the year 2006 urban land cover than that under the 1986 urban land cover. The conversion from rural land use to urban land type also strengthens the local lake-land breeze circulations in this area and modifies the vertical wind speed field.

    三亚市作为我国唯一的热带滨海旅游城市,在建设国际旅游岛空前繁荣的背景下,大量的城市移民和游客涌入,导致市区内部交通拥堵、环境恶化,城市空间向周边腹地快速无序扩展.为解决城市发展与环境的矛盾,遵循景观生态规划原则,提出从市域、市区两个层次入手,规划未来三亚市的空间结构.市域空间结构组织采用复合指状模式,旨在完善三亚市景观生态安全格局。高效发挥自然资源的生态效应;市区空间外拓采用网络组团模式,以期打造各个组团特色,增加组团间联系,强化不同分区的生态功能.%As the only tropical seashore tourist city of China, Sanya is trying to become an international tourist destination. Meanwhile, the city experiences large flux of urban immigrants and tourists, causing urban issues such as traffic congestion, environment deterioration, and rapid urban sprawl. In order to solve the contradiction between urban development and environment, following the principles of landscape ecologycal planning, this paper puts forward the idea of spatial structure planning of Sanya from the level of city territory and urban district. City territory spatial structure uses an enhanced palm model, aiming at improving the threshold landscape pattern and boosting the ecological effect of natural resources. Urban district space expansion design is based on the network grouping model, so that distinctive ecological functions can be expressed explicitly.

  6. CityGML - Interoperable semantic 3D city models

    2012-07-01

    CityGML is the international standard of the Open Geospatial Consortium (OGC) for the representation and exchange of 3D city models. It defines the three-dimensional geometry, topology, semantics and appearance of the most relevant topographic objects in urban or regional contexts. These definitions are provided in different, well-defined Levels-of-Detail (multiresolution model). The focus of CityGML is on the semantical aspects of 3D city models, its structures, taxonomies and aggregations, allowing users to employ virtual 3D city models for advanced analysis and visualization tasks in a variety of application domains such as urban planning, indoor/outdoor pedestrian navigation, environmental simulations, cultural heritage, or facility management. This is in contrast to purely geometrical/graphical models such as KML, VRML, or X3D, which do not provide sufficient semantics. CityGML is based on the Geography Markup Language (GML), which provides a standardized geometry model. Due to this model and its well-defined semantics and structures, CityGML facilitates interoperable data exchange in the context of geo web services and spatial data infrastructures. Since its standardization in 2008, CityGML has become used on a worldwide scale: tools from notable companies in the geospatial field provide CityGML interfaces. Many applications and projects use this standard. CityGML is also having a strong impact on science: numerous approaches use CityGML, particularly its semantics, for disaster management, emergency responses, or energy-related applications as well as for visualizations, or they contribute to CityGML, improving its consistency and validity, or use CityGML, particularly its different Levels-of-Detail, as a source or target for generalizations. This paper gives an overview of CityGML, its underlying concepts, its Levels-of-Detail, how to extend it, its applications, its likely future development, and the role it plays in scientific research. Furthermore, its

    Impact cratering is the dominant geological process on the Moon, Near Earth Asteroids (NEAs) and the moons of Mars - the objectives for the new Solar System Exploration Research Virtual Institute (SSERVI). Led by members of the Canadian Lunar Research Network (CLRN), funded by the Canadian Space Agency, and with participants from the U.S., we carried out a series of analogue missions on Earth in order to prepare and train for future potential robotic and human sample return missions. Critically, these analogue missions were driven by the paradigm that operational and technical objectives are conducted while conducting new science and addressing real overarching scientific objectives. An overarching operational goal was to assess the utility of a robotic field reconnaissance mission as a precursor to a human sortie sample return mission. Here, we focus on the results and lessons learned from a robotic precursor mission and follow on human-robotic mission to the Mistastin Lake impact structure in Labrador, northern Canada (55°53'N; 63°18'W). The Mistastin structure was chosen because it represents an exceptional analogue for lunar craters. This site includes both an anorthositic target, a central uplift, well-preserved impact melt rocks - mostly derived from melting anorthosite - and is (or was) relatively unexplored. This crater formed ~36 million years ago and has a diameter of ~28 km. The scientific goals for these analogue missions were to further our understanding of impact chronology, shock processes, impact ejecta and potential resources within impact craters. By combining these goals in an analogue mission campaign key scientific requirements for a robotic precursor were determined. From the outset, these analogue missions were formulated and executed like an actual space mission. Sites of interest were chosen using remote sensing imagery without a priori knowledge of the site through a rigorous site selection process. The first deployment occurred in

    Full Text Available The current study analyzes the structure and some features of two urban metapopulations of the Balkan Wall Lizard (Podarcis tauricus (Pallas, 1814 from Nature Monument (NM “Mladezhki halm” and Nature Monument “Halm na osvoboditelite” in the city of Plovdiv (South Bulgaria. In both study sites, the Balkan Wall lizard inhabits exclusively the interior of the hills and prefers mainly open areas with rare grass and shrub vegetation. The recorded dominant plant species are not autochthonous for the hills, but gradually displaced with many decorative species, used widely in the gardening and thecity parks. The population abundance from both hills is relatively low, with higher values in NM “Mladezhki halm” and generally shows a decrease pattern for the two year period. In the hills of Plovdiv, the Balkan Wall lizard shows a bimodal diurnal and seasonal activity. Both metapopulations showed a sex ratio close to 1:1 with a slight superiority of the females (1:1.29, but with no statistically significant deviation. The age structure of both metapopulations is almost identical - the highest percentage takes the adults, followed by the subadults and juveniles, with no significant deviations from the normal ratio. The possible reasons for the contemporary distribution and population structure of the Balkan Wall lizard are discussed. Historic land use change and its effect on the populations are discussed as well. The main risks for this species in the city of Plovdiv are construction and forestation (destruction of open terrains. Nevertheless, the Balkan Wall lizard seems to have successfully overcome the risks of urbanization and its population seem stable and sustainable.

  13. Lessons from the Sun

    2011-07-01

    Full Text Available In this brief note, the implications of a condensed Sun will be examined. A celestial body composed of liquid metallic hydrogen brings great promise to astronomy, relative to understanding thermal emission and solar structure. At the same time, as an incom- pressible liquid, a condensed Sun calls into question virtually everything which is cur- rently believed with respect to the evolution and nature of the stars. Should the Sun be condensed, then neutron stars and white dwarfs will fail to reach the enormous densities they are currently believed to possess. Much of cosmology also falls into question, as the incompressibility of matter curtails any thought that a primordial atom once existed. Aging stars can no longer collapse and black holes will know no formative mechanism. A condensed Sun also hints that great strides must still be made in understanding the nature of liquids. The Sun has revealed that liquids possess a much greater potential for lattice order than previously believed. In addition, lessons may be gained with regards to the synthesis of liquid metallic hydrogen and the use of condensed matter as the basis for initiating fusion on Earth.

    2004-08-01

    The idea that music makes you smarter has received considerable attention from scholars and the media. The present report is the first to test this hypothesis directly with random assignment of a large sample of children (N = 144) to two different types of music lessons (keyboard or voice) or to control groups that received drama lessons or no lessons. IQ was measured before and after the lessons. Compared with children in the control groups, children in the music groups exhibited greater increases in full-scale IQ. The effect was relatively small, but it generalized across IQ subtests, index scores, and a standardized measure of academic achievement. Unexpectedly, children in the drama group exhibited substantial pre- to post-test improvements in adaptive social behavior that were not evident in the music groups. PMID:15270994

    2010-05-01

    In Scotland the new science curriculum for pupils aged 12 to 15 shall include the following outcomes: "Using my knowledge and understanding, I can express an informed view on a national or global environmental issue;" "I have participated in constructing a model to harness a renewable source of energy and can investigate how to optimise the output;" and "I can discuss why it is important to me and to the future of the world that alternatives to fossil fuels are developed." There will be an emphasis on creating lessons that will nurture responsible citizens, improve pupil engagement and allow students to develop their team working skills. To help teachers plan lessons to address this, the Scottish Schools Equipment Research Centre and Edinburgh University made teaching materials on four renewable energy resources. This poster describes how their suggested activities on solar cells, wind turbines, hydroelectric power stations and wave power were used in science lessons with twelve year old students. After an initial class discussion based on issues related to climate change and diminishing fossil fuel supplies, a workshop activity was carried out in three stages. The students were issued with a fact sheet about one of four imaginary islands (Skisdale, Cloudy Island, Surfsville and Sun City) and they were asked to work in teams to choose the most suitable method of generating electricity for their island. Issues such as costs, where it will be sited and environmental implications were considered. They were then asked to conduct practical activities by constructing and testing models for these forms of renewable energy. To conclude, they presented their proposal to the rest of the class with reasoned explanations. The kits used in the lessons can be purchased from Anderson Scientific (sales@andersonscientific.co.uk). The solar cells were simply connected to a voltmeter. The wind and hydroelectric groups used the same basic equipment. This was made using a small water

  2. Sustainable cities and energy policies

    International Nuclear Information System (INIS)

    This book starts out with the optimistic perspective that modern cities can indeed play a strategic role in the necessary pathway to sustainable development, with particular emphasis on the opportunities offered by local energy and environmental initiatives. Our study aims to demonstrate that an urban sustainability policy has many socio-economic benefits, while it also seeks to identify the critical success and failure factors of sustainable city innovations. After a comprehensive review of various opportunities and experiences, attention is focused particularly on renewable energy resources which may offer new potential for the active involvement of local authorities. The study also highlights major impediments regarding the adoption and implementation of renewable energies, in particular, the development of advanced energy-environmental technology in a world dominated by natural (public) monopolies and/or monopolistic competition elements. In this context both theoretical and empirical elements are discussed, as well as institutional aspects. The theory and methodology is tested by a thorough empirical investigation into local renewable energy initiatives in three European countries, viz. Greece, Italy and The Netherlands. Based on an extensive data base, various statistical models are estimated in order to identify the key elements and major driving forces of sustainable development at the city level. And finally, the study is concluded with a long list of applicable and operational policy guidelines for urban sustainability. These lessons are largely based on meta-analytic comparative studies of the various initiatives investigated. (orig.)

  3. The hybrid outcome of urban change: global city, polarized city?

    Directory of Open Access Journals (Sweden)

    Ayat Ismail

    2013-12-01

    Full Text Available A wide range of studies supports the assumption that levels of socio-spatial polarization, segregation, and exclusion are rising in global cities over the past decades as a direct outcome of certain global processes, such as the deindustrialization process, its associated changes in division of labor, and declined redistributive power of the welfare state. However, that assumption – known as the polarization thesis – is criticized based on several contentions, including the oversimplification of the global/local interplay by overlooking the role of local contingent factors that may modify, intensify, or reverse the expected socio-spatial outcome in individual cities. This study aims to capture the hybrid nature of the socio-spatial outcomes of global cities by proving that the complex process of restructuring of cities is a form of structural and chronological hybridity. Through providing a solid empirical ground for investigating the general applicability of the socio-spatial polarization thesis, as well as evaluating the influence of local contexts of cities on the outcomes of urban change. The research offers a theoretical review of the multifaceted restructuring of global cities. Then, the macro trends of global economy are linked to their micro outcomes (segregation patterns within cities, through understanding the implications of cities’ economic functions on local urban policies and housing markets. Finally, the changes in socioeconomic segregation over the past decades are calculated for a large dataset of 66 global cities. The collective result of the analysis shows the downfalls of the generalized hypothesis. While the discussion of individual cities highlights certain contextual particularities, that are contributing to the production of unique socio-spatial configurations in different global cities.

    The present paper reviews the history leading up to the rejection of the proposal to build a Rock Characterization Facility (RCF) in 1997 and discuss the lessons learned by its promoter, United Kingdom Nirex, from analysis of past approaches. The lessons are considered under the following headings: process (policy development and implementation), structure (an independent organization responsible for long term radioactive waste management), and behaviour (the need for openness, transparency and accountability in future processes). On the basis of these lessons, the paper points the way forward for resolving the problem of radioactive waste management in the UK. (author)

    What happened at TMI-2 and to the United States Nuclear Industry since the accident to that plant is recounted. Four main points are made: commercial use of nuclear power evolved so rapidly that neither industry nor society generally, was able to assimilate this dramatically new technology fast enough; accidents like TMI-2, and now, the much more damaging Chernobyl, are a part of the price paid; we must take every possible step so that the risks from nuclear power are reduced by learning from accidents and putting that knowledge into practice; the lessons learned and applied after TMI-2 have tended to be the readily achievable, shorter term ones. The most drastic changes will take more time. The organizational and institutional lessons are considered first, then the technical ones. The sequence and status of the TMI-2 cleanup is discussed. The design lessons are summarized. (author)

    Full Text Available The main issue in determining the seismic vulnerability is having a comprehensive view to all probable damages related to earthquake occurrence. Therefore, taking factors such as peak ground acceleration (PGA in the time of earthquake occurrence, the type of structures, population distribution among different age groups, level of education, the physical distance to a hospitals (or medical care centers, etc. into account and categorized under four indicators of geotechnical, structural, social and physical distance to needed facilities and distance from dangerous ones will provide us with a better and more exact outcome. To this end in this paper using analytic hierarchy process (AHP, the amount of importance of criteria or alternatives are determined and using geographical information system (GIS, the vulnerability of Tehran metropolitan as a result of an earthquake, is studied. This study focuses on the fact that Tehran is surrounded by three active and major faults of the Mosha, North Tehran and Rey. In order to comprehensively determine the vulnerability, three scenarios are developed. In each scenario, seismic vulnerability of different areas in Tehran city is analysed and classified into four levels including high, medium, low and safe. The results show that regarding seismic vulnerability, the faults of Mosha, North Tehran and Rey respectively make 6, 16 and 10% of Tehran area highly vulnerable and also 34, 14 and 27% are safe.

    2008-01-01

    This paper studies a landfill where there are three faults running through. As serious pollution has occurred to the geological environment, the landfill is to be closed up and renovated. The paper aims to explore the role of fracture structure in leachate pollution at the landfill. The research was carried out in several stages. First, mathematical models of the pre-renovation landfill with three faults running through and the landfill after renovation were established. And then, the boundary conditions and parameters of the two mathematical models were determined. The groundwater level of the landfills was simulated in order to modify the two mathematical models. As a result, a feasiblema the matical model was achieved. Based on this model, a comparison was made of the COD concentration variations in the inside leachate and outside ieachate between the two landfills. Accordingly, the impacts of the fracture structure on the pollution of leachate at the landfills could be identified. The study results show that while faults contribute to the migration of leachate, they also serve as a confluence of leachate, thus further deteriorating the environment. The COD concentrations of the inside leachate and the outside leachate of the pre-renovation landfill are respectively 800 mg/Land 220 mg/L higher than those of the post-renovation landfill. Therefore, measures must be taken to handle the leachate seepage in areas where there are faults as well as the neighboring areas so as to get the environmental pollution under control.

    Full Text Available Research on the geographical structure of the flora of Podgorica revealed that 85.9% of the species are native, while 14.1% are non-native. This ratio is typical of Mediterranean settlements, where even the most urbanized region reflects the overall character of the surrounding flora. In terms of chorologic groups, the three largest are: eury-Mediterranean (18.2%, cosmopolitan (12.6%, and steno-Mediterranean (8.3%. The percentage of endemic and subendemic plants is also significant (6.8%. Within the group of aliens, species of Asian origin prevail. Comparative analysis of the chorologic spectra of Podgorica, Rome, Patras, and Salonika revealed some similarities.

    Full Text Available Structural and qualitative evaluation of Revised National Tuberculosis Control Programme (RNTCP is important to determine actual status of the programme in the field settings and to uncover the concealed gaps. The present cross-sectional study assessed the infrastructural facilities and quality of services provided through microscopy and directly observed treatment (DOT centers at Nanded city of Maharashtra. The investigator made on spot observation on the activities at microscopy and DOT centers and assessed the infrastructural facilities using an observational checklist. Expert microbiologist cross checked the microscopy report done by the laboratory technicians. It revealed that retrieval mechanism was not functioning in more than half of the DOT centers. Only 5 DOT providers were trained in RNTCP. Stock of sputum containers, methylene blue, and carbol fuchsin was found to be inadequate at some microscopy centers. Half of the laboratory technicians reported high false positive result in spite of being trained. Improvement of infrastructural and logistic support along with the refreshing training for the workers are needed for effective implementation of RNTCP.

    The preservation of historic cities requires a balance between conservation and development because the urban structures of the old and new city are interwoven on same space. Existing restoration plans rely on old records and excavation reports and are based on the present topography. However, historic cities have undergone significant natural and anthropogenic topographic changes such as alluvial sediment accumulation and uneven terrain construction. Therefore, considering only the present topography is misleading. Thus, to understand a historic city's structure more appropriately, it is necessary to comprehend the ancient geographic environment. This study provides an analysis and GIS visualization of the ancient topography of a historic city, Sabi capital city of the Baekje Dynasty, which collapsed 1,500 years ago.

    2016-03-01

    Uruk archaeological site, which located in Al-Muthanna Governorate southern Iraq, was investigated by integrated geophysical methods, ground penetration radar (GPR) and electric resistivity tomography (ERT) to image the historical buried structures. The GPR images show large radar attributes characterized by its continuous reflections having different widths. GPR attributes at shallower depth are mainly representing the upper part of Babylonian Houses that can often be found throughout the study area. In addition, radargrams characterized objects such as buried items, buried trenches and pits which were mainly concentrated near the surface. The ERT results show the presence of several anomalies at different depths generally having low resistivities. It is clear that the first upper zone can be found throughout the whole area and it may represent the top zone of the Babylonian houses. This zone is characterized by its dry clay and sandy soil containing surface broken bricks and slag mixed with core boulders. The second one underneath the top shows a prominent lower resistivity zone. It is probably caused by the moisture content that reduces the resistivity. The thickness of this zone is not equal at all parts of the site. The third deeper zone typically represents the archaeological walls. Most of the main anomalies perhaps referred to the buried clay brick walls. The map of the archaeological anomalies distribution and 3D view of the foundations at the study area using GPR and ERT techniques clearly show the characteristics of the Babylonian remains. A contour map and 3D view of Uruk show that the archaeological anomalies are concentrated mainly at the NE part of the district with higher values of wall height that range between 6 and 8 m and reach to more than 10 m. At the other directions, there are fewer walls with lower heights of 4-6 m and reach in some places the wall foot.

    West, Geoffrey

    2013-04-01

    Many of the most challenging, exciting and profound questions facing science and society, from the origins of life to global sustainability, fall under the banner of ``complex adaptive systems.'' This talk explores how scaling can be used to begin to develop physics-inspired quantitative, predictive, coarse-grained theories for understanding their structure, dynamics and organization based on underlying mathematisable principles. Remarkably, most physiological, organisational and life history phenomena in biology and socio-economic systems scale in a simple and ``universal'' fashion: metabolic rate scales approximately as the 3/4-power of mass over 27 orders of magnitude from complex molecules to the largest organisms. Time-scales (such as lifespans and growth-rates) and sizes (such as genome lengths and RNA densities) scale with exponents which are typically simple multiples of 1/4, suggesting that fundamental constraints underlie much of the generic structure and dynamics of living systems. These scaling laws follow from dynamical and geometrical properties of space-filling, fractal-like, hierarchical branching networks, presumed optimised by natural selection. This leads to a general framework that potentially captures essential features of diverse systems including vasculature, ontogenetic growth, cancer, aging and mortality, sleep, cell size, and DNA nucleotide substitution rates. Cities and companies also scale: wages, profits, patents, crime, disease, pollution, road lengths scale similarly across the globe, reflecting underlying universal social network dynamics which point to general principles of organization transcending their individuality. These have dramatic implications for global sustainability: innovation and wealth creation that fuel social systems, left unchecked, potentially sow the seeds for their inevitable collapse.

    Full Text Available Socially just, intergenerational urban spaces should not only accommodate children and adolescents, but engage them as participants in the planning and design of welcoming spaces. With this goal, city agencies in Boulder, Colorado, the Boulder Valley School District, the Children, Youth and Environments Center at the University of Colorado, and a number of community organizations have been working in partnership to integrate young people’s ideas and concerns into the redesign of parks and civic areas and the identification of issues for city planning. Underlying their work is a commitment to the Convention on the Rights of the Child and children’s rights to active citizenship from a young age. This paper describes approaches used to engage with young people and methods of participation, and reflects on lessons learned about how to most effectively involve youth from underrepresented populations and embed diverse youth voices into the culture of city planning.

    Phase 3 of Project WISH saw the evolution of the Emerald City (E-City) from a collection of specialized independent analyses and ideas to a working structural design integrated with major support systems and analyses. Emphasis was placed on comparing and contrasting the closed and open cycle gas core nuclear rocket engines to further determine the optimum propulsive system for the E-City. Power and thermal control requirements were then defined and the question of how to meet these requirements was addressed. Software was developed to automate the mission/system/configuration analysis so changes dictated by various subsystem constraints could be managed efficiently and analyzed interactively. In addition, the liquid hydrogen propellant tank was statically designed for minimum mass and shape optimization using a finite element modeling package called SDRC I-DEAS. Spoke and shaft cross-sectional areas were optimized on ASTROS (Automated Structural Optimization System) for mass minimization. A structural dynamic analysis of the optimal structure also conducted using ASTROS enabled a study of the modes, frequencies, displacements, and accelerations of the E-City. Finally, the attitude control system design began with an initial mass moment of inertia analysis and was then designed and optimized using linear quadratic regulator control theory.

    This document (Volume I) provides an executive summary of the lessons learned from the Constellation Program. A companion Volume II provides more detailed analyses for those seeking further insight and information. In this volume, Section 1.0 introduces the approach in preparing and organizing the content to enable rapid assimilation of the lessons. Section 2.0 describes the contextual framework in which the Constellation Program was formulated and functioned that is necessary to understand most of the lessons. Context of a former program may seem irrelevant in the heady days of new program formulation. However, readers should take some time to understand the context. Many of the lessons would be different in a different context, so the reader should reflect on the similarities and differences in his or her current circumstances. Section 3.0 summarizes key findings developed from the significant lessons learned at the program level that appear in Section 4.0. Readers can use the key findings in Section 3.0 to peruse for particular topics, and will find more supporting detail and analyses in Section 4.0 in a topical format. Appendix A contains a white paper describing the Constellation Program formulation that may be of use to readers wanting more context or background information. The reader will no doubt recognize some very similar themes from previous lessons learned, blue-ribbon committee reviews, National Academy reviews, and advisory panel reviews for this and other large-scale human spaceflight programs; including Apollo, Space Shuttle, Shuttle/Mir, and the ISS. This could represent an inability to learn lessons from previous generations; however, it is more likely that similar challenges persist in the Agency structure and approach to program formulation, budget advocacy, and management. Perhaps the greatest value of these Constellation lessons learned can be found in viewing them in context with these previous efforts to guide and advise the Agency and its

    If one ranks cities by population, the rank of a city is inversely related to its size, a well-documented phenomenon known as Zipf's Law. Further, the growth rate of a city's population is uncorrelated with its size, another well-known characteristic known as Gibrat's Law. In this paper, I show that both characteristics are true of countries as well as cities; the size distributions of cities and countries are similar. But theories that explain the size-distribution of cities do not obviously...

    Based on the continuous stationary measurements of climate carried out since the summer of 1992 at various sites in the Leipzig area and for mobile air temperature and humidity measurements carried out for in situ weather in the city area at selected test areas, relationships were carried out between urban structures for using areas and climatic conditions of the air layer near the ground in the city of Leipzig region. The data on the sealing of the functional types of structures obtained in the context of a further part project were used as an important indicator for the use of areas. A basic precondition for these city climate investigations is the preparation of the extensive data obtained in the form of tables and graphs. (orig./KW) [Deutsch] Auf der Basis der seit Sommer 1992 an verschiedenen Standorten im Raum Leipzig kontinuierlich vorgenommenen stationaeren Klimamessungen und bei autochthonen Wetterlagen im Stadtgebiet und in ausgewaehlten Testgebieten durchgefuehrten mobilen Lufttemperatur- und -feuchtemessungen wurden Beziehungen zwischen urbanen Flaechennutzungsstrukturen und klimatischen Verhaeltnissen der bodennahen Luftschicht in der Stadtregion Leipzig erarbeitet. Als wesentlicher Indikator fuer die Flaechennutzung fanden die im Rahmen eines weiteren Teilvorhabens gewonnenen Angaben zur Versiegelung der funktionalen Strukturtypen Verwendung. Eine Grundvoraussetzung fuer diese stadtklimatischen Untersuchungen stellt die Aufarbeitung des gewonnenen umfangreichen Datenmaterials in Form von Tabellen und Grafiken dar. (orig./KW)

    The Mayan culture collected exquisite astronomical data for over a millennium. However, it failed to come up with the breakthrough ideas of modern astronomy because the data was analyzed within a mythological culture of astrology that rested upon false but mathematically sophisticated theories about the Universe. Have we learned the necessary lessons to prevent our current scientific culture from resembling Mayan Astronomy? Clearly, data collection by itself is not a guarantee for good science as commonly assumed by funding agencies. A vibrant scientific culture should cultivate multiple approaches to analyzing existing data and to collecting new data.

    1997-03-01

    Advances in cognitive psychology and in research techniques have led to an increase in the acceptance of the conception of teaching as a “thoughtful” profession. The interest and enthusiasm of researches in aspects of teacher cognition demonstrate a shift from an emphasis on observable teacher behaviours to a focus on a teacher's unobservable thinking process. In this study, a qualitative approach was used to uncover a teacher's thinking process during lesson planning, to depict a more holistic view of the structural complexity of teacher cognition during lesson planning. Specialised science teachers and general teachers who had different levels of subject expertise were studied. The teachers were interviewed on how they planned an elementary science lesson. Interview protocols were analysed using a taxonomy which assessed the cognitive complexity of teacher thinking. Differences were found between specialised science teachers and general teachers in the levels of structural complexity in their thinking process.

    In 1993 mayors from 50 cities in 20 countries gathered at the UN in New York under the umbrella of the International Council for Local Environmental Initiatives (ICLEI) to issue a declaration aimed at cutting carbon dioxide emissions from cities. By today 465 cities report their GHG emissions in ICLEIs carbonn Cities Climate Registry (cCR) . Many cities worldwide are on the route to implement the combined new standard for city-based GHG accounting and reporting, named the Global Protocol for Community-Scale GHG Emissions (GPC). These extensive data sources offer the unique chance to better understand, manage and reduce city GHG emissions. However, many cities are already reporting or have reported their GHG emission in non GPC conform tools. This heterogeneous data source raises the question on how these data could be potentially transferred to a GPC conform level. For the transfer process it is very important to understand and quantify the potential losses of information and increase or decrease in uncertainty due to class conversions and associated recalculations of GHG data. Here we compare existing GHG reports from different sources based on the use of different tools. We look at data from the carbonn Registry by ICLEI, the CDP, C40 and the Ecoregion tool. Using examples of existing data form cities in Europe we demonstrate potential information losses and inconsistencies leading to increased uncertainty. We also illustrate the potential mapping schemes for the data structures and identify uncertainties from using alternative mappings. In conclusion it is essential to develop consistent data structures in order to allow the use of city GHG data for time series analysis and city intercomparison.

    This paper shows that Zipf's Law for cities can emerge as a property of a clustering process. If initially uniformly distributed people chose their location based on a specific gravity equation as found in trade studies, they will form cities that follow Zipf's Law in expected value. This view of cities as spatial agglomerations is supported empirically by the observation that larger cities are surrounded by larger hinterland areas and larger countryside populations.

    Industrial transformation represents a unique economic phenomenon in China's regional economy,and old industrial city reconstruction has long been a key problem that affects state security. As a typical old indus-trial city in China, Shenyang established its heavy industrial city position in the First Five-year Plan period (1953-1957), and this industrial structure has been consolidated for a long time. After 1978, Shenyang began its long last-ing industrial reconstruction in an all-round way by 3 main initiatives including restructuring economic system, up-grading traditional industrial technology and developing high-tech industry. In the end of the 1990s, it could be I-dentified that remarkable structural changes took place in city economy at large as well as individual industrial sec-tor. According to the GDP proportion change, Shenyang is on the way to a high level industrial structure. The sec-ondary industry also engendered significant shifting as smelting and textile industry declined sharply but IT industry increased largely. Although the ratio of the heavy industry to the light industry changed periodically, the heavy in-dustrial output value most time kept a high proportion over 60% of the gross industrial output value in the past five decades. Shenyang has favorable conditions for developing equipment manufacturing industry, but it should carry out the program by establishing its leading role in urban economy plan, building "Theme Industrial Parks", improv-ing Tiexi Industrial Zone, removing any kind of system barrier, enlarging private and other ownerships economy and improving technology, marketing and management by IT application. In response to economy globalization,Shenyang needs to expand the cooperation worldwide and improve the cohesion with surrounding cities.

    Rybski, Diego; Kropp, Jürgen P

    2012-01-01

    Urban agglomerations exhibit complex emergent features of which Zipf's law, i.e. a power-law size distribution, and fractality may be regarded as the most prominent ones. We propose a simplistic model for the generation of city-like structures which is solely based on the assumption that growth is more likely to take place close to inhabited space. The model involves one parameter which is an exponent determining how strongly the attraction decays with the distance. In addition, the model is run iteratively so that existing clusters can grow and new ones can emerge. The model is capable of reproducing the size distribution and the fractality of the hull of the largest cluster. While the power-law distribution depends on both, the imposed exponent and the iteration, the fractality seems to be independent of the former and only depends on the latter.

In order to increase visual quality of cities and make cities more liveable landscape architects use not only living materials such as plants but also nonliving materials. This study was carried out to investigate the effects of surrounding elements which are vertical elements in landscape designs, on functional and city aesthetics. With this aim, materials used in surrounding elements around houses in Erzurum, houses surrounded by these elements and their harmony with their surroundings, aesthetics and functional effects were investigated and their contributions to city image were determined. While surrounding elements are mainly adequate in functions, they are lower quality in aesthetics.

Addressing this issue, the article draws an analogy between a human person and a city. Like a city, a human being needs to comprehend his self-identity in order to resist depressive tendencies. It is shown that a person’s depressive symptoms are similar to those of cities. The city identity necessary to resist depression can be searched for both historically and geographically. The historical aspect consists of local myths and legends about the city and the citizens. The geographical aspect of identity comprises features of the terrain, climate, flora and fauna of the region where the city is located.

Today, the primary objective of spatial planning is not only to form a proper connection between function and space but also to balance public and private interests. Constantly developed geographic spatial information systems allow not only for easy navigation around the city, but more importantly for more advanced analyses, such as the recognition of the current trends in estate development, communication systems, changes in agricultural and forest areas. The main objective of the research is to define functional-spatial links determined by social-economic needs reflected in local plans and to verify the similarities between local plans, that were drawn up in three different periods (PRL, the transition period, and in accordance with nowadays applicable laws, how the changing economic, social goals and current needs of the city affected the continuation of the adopted solutions. The study shows that despite changes in the law and abandoning the idea of industrial city, in which the landscape is dominated by blast furnaces and mine shafts, the basic trend has been maintained and local plans prepared in subsequent years form a continuum, and despite the different scales of development are closely linked. At the same time it has been shown that modern GIS tools enable verification of the continuity of spatial policy of the municipality.

    The US DOE Office of Legacy Management (LM) is the long-term steward for 90 sites remediated under numerous regulatory regimes including the Formerly Utilized Sites Remedial Action Program (FUSRAP) sites. In addition, LM holds considerable historical information, gathered in the 1970s, to determine site eligibility for remediation under FUSRAP. To date, 29 FUSRAP sites are in LM’s inventory of sites for long-term surveillance and maintenance (LTS&M), and 25 are with the US Army Corps of Engineers (USACE) for remediation or in the process of being transitioned to LM. It is forecasted that 13 FUSRAP sites will transfer from the USACE to LM over the next 10 years; however, the timing of the transfers is strongly dependent upon federal funding of the ongoing remedial actions. Historically, FUSRAP sites were generally cleaned up for “unrestricted” industrial use or remediated to the “cleanup standards” at that time, and their use remained unchanged. Today, these sites as well as the adjacent properties are now changing or envisioned to have changes in land use, typically from industrial to commercial or residential uses. The implication of land-use change affects DOE’s LTS&M responsibility for the sites under LM stewardship as well as the planning for the additional sites scheduled to transition in time. Coinciding with land-use changes at or near FUSRAP sites is an increased community awareness of these sites. As property development increases near FUSRAP sites, the general public and interested stakeholders regularly inquire about the sufficiency of cleanups that impact their neighborhoods and communities. LM has used this experience to address a series of lessons learned to improve our program management in light of the changing conditions of our sites. We describe these lessons learned as (1) improved stakeholder relations, (2) enhanced LTS&M requirements for the sites, and (3) greater involvement in the transition process.

    Lesson "Balance in Nature" This simulation game-lesson (Balance in Nature) gives an opportunity for the students to show creativity, work independently, and to create models and ideas. It creates future-oriented thought connected to their experience, allowing them to propose solutions for global problems and personal responsibility for their activities. The class is divided in two teams. Each team chooses questions. 1. Question: Pollution in the environment. 2. Question: Care for nature and climate. The teams work on the chosen tasks. They make drafts, notes and formulate their solutions on small pieces of paper, explaining the impact on nature and society. They express their points of view using many different opinions. This generates alternative thoughts and results in creative solutions. With the new knowledge and positive behaviour defined, everybody realizes that they can do something positive towards nature and climate problems and the importance of individuals for solving global problems is evident. Our main goal is to recover the ecological balance, and everybody explains his or her own well-grounded opinions. In this work process the students obtain knowledge, skills and more responsible behaviour. This process, based on his or her own experience, dialogue and teamwork, helps the participant's self-development. Making the model "human↔ nature" expresses how human activities impact the natural Earth and how these impacts in turn affect society. Taking personal responsibility, we can reduce global warming and help the Earth. By helping nature we help ourselves. Teacher: Veselina Boycheva-Chapanova " Saint Patriarch Evtimii" Scholl Str.

    2006-01-01

    Given the far-reaching effects of the terrorist attacks on September 11, 2001, a study was conducted under the supervision of the New York State Office of Alcoholism and Substance Abuse Services to assess the impact on New York City's substance abuse treatment programs. A stratified, random sample of 15 treatment programs was selected to represent the system's major modalities. Administrators representing these programs were interviewed face-to- face using a structured interview schedule. The questions mainly probed the problems experienced on 9/11 and afterwards, patient issues and the lessons learned. The findings show major concerns for the mental health of both staff members and patients, the failure of the telephone communication system, the particular sensitivity of drug-free outpatient clinics, the challenges experienced by methadone programs, and the need to update disaster planning. A host of problems came to the fore now requiring another level of thinking. PMID:16597568

    2010-01-01

    The spatial arrangement of urban hubs and centers and how individuals interact with these centers is a crucial problem with many applications ranging from urban planning to epidemiology. We utilize here in an unprecedented manner the large scale, real-time 'Oyster' card database of individual person movements in the London subway to reveal the structure and organization of the city. We show that patterns of intraurban movement are strongly heterogeneous in terms of volume, but not in distance, and that there is a polycentric structure composed of simple flow patterns organized around a limited number of activity centers arranged in a hierarchical way. This new understanding can shed light on the impact of new urban projects on the evolution of the polycentric configuration of a city and provides an initial approach to modeling flows in an urban system.

  13. Biophilic Cities Are Sustainable, Resilient Cities

    Directory of Open Access Journals (Sweden)

    Peter Newman

    2013-08-01

    Full Text Available There is a growing recognition of the need for daily contact with nature, to live happy, productive, meaningful lives. Recent attention to biophilic design among architects and designers acknowledges this power of nature. However, in an increasingly urban planet, more attention needs to be aimed at the urban scales, at planning for and moving towards what the authors call “biophilic cities”. Biophilic cities are cities that provide close and daily contact with nature, nearby nature, but also seek to foster an awareness of and caring for this nature. Biophilic cities, it is argued here, are also sustainable and resilient cities. Achieving the conditions of a biophilic city will go far in helping to foster social and landscape resilience, in the face of climate change, natural disasters and economic uncertainty and various other shocks that cities will face in the future. The paper identifies key pathways by which biophilic urbanism enhances resilience, and while some are well-established relationships, others are more tentative and suggest future research and testing.

    Many urban phenomena exhibit remarkable regularity in the form of nonlinear scaling behaviors, but their implications on a system of networked cities has never been investigated. Such knowledge is crucial for our ability to harness the complexity of urban processes to further sustainability science. In this paper, we develop a dynamical modeling framework that embeds population-resource dynamics-a generalized Lotka-Volterra system with modifications to incorporate the urban scaling behaviors-in complex networks in which cities may be linked to the resources of other cities and people may migrate in pursuit of higher welfare. We find that isolated cities (i.e., no migration) are susceptible to collapse if they do not have access to adequate resources. Links to other cities may help cities that would otherwise collapse due to insufficient resources. The effects of inter-city links, however, can vary due to the interplay between the nonlinear scaling behaviors and network structure. The long-term population level of a city is, in many settings, largely a function of the city's access to resources over which the city has little or no competition. Nonetheless, careful investigation of dynamics is required to gain mechanistic understanding of a particular city-resource network because cities and resources may collapse and the scaling behaviors may influence the effects of inter-city links, thereby distorting what topological metrics really measure.

    We study the optimal and equilibrium size of cities in a monocentric city model with environmental pollution. Pollution is related to city size through the effect of population on production, commuting, and housing consumption. If pollution is local, we find that equilibrium cities are too large, mirroring standard results in the theory of city systems. When pollution is global and per capita pollution declines with city size, however, equilibrium cities may be too small.

  18. Extreme Rainfall In A City

    Science.gov (United States)

    Nkemdirim, Lawrence

    Cities contain many structures and activities that are vulnerable to severe weather. Heavy precipitation cause floods which can damage structures, compromise transportation and water supply systems, and slow down economic and social activities. Rain induced flood patterns in cities must be well understood to enable effective placement of flood control and other regulatory measures. The planning goal is not to eliminate all floods but to reduce their frequency and resulting damage. Possible approaches to such planning include probability based extreme event analysis. Precipitation is normally the most variable hydrologic element over a given area. This variability results from the distribution of clouds and in cloud processes in the atmosphere, the storm path, and the distribution of topographical features on the ground along path. Some studies suggest that point rainfall patterns are also affected by urban industrial effects hence some agreement that cities are wetter than the country surrounding them. However, there are still questions regarding the intra- urban distribution of precipitation. The sealed surfaces, urban structures, and the urban heat anomaly increase convection in cities which may enhance the generation of clouds. Increased dust and gaseous aerosols loads are effective condensation and sublimation nuclei which may also enhance the generation of precipitation. Based on these associations, the greatest amount of convection type rainfall should occur at city center. A study of summer rainfall in Calgary showed that frequencies of trace amounts of rainfall and events under 0.2mm are highest downtown than elsewhere. For amounts greater than than 0.2 mm, downtown sites were not favored. The most compelling evidence for urban-industrial precipitation enhancement came from the Metromex project around St. Loius, Missouri where maximum increases of between 5 to 30 per cent in summer rainfall downwind of the city was linked to urbanization and

    Full Text Available Progressive cities worldwide have demonstrated political leadership by initiating meaningful strategies and actions to tackle climate change. However, the lack of knowledge concerning embodied greenhouse gas (GHG emissions of cities has hampered effective mitigation. We analyse trans-boundary GHG emission transfers between five Australian cities and their trading partners, with embodied emission flows broken down into major economic sectors. We examine intercity carbon footprint (CF networks and disclose a hierarchy of responsibility for emissions between cities and regions. Allocations of emissions to households, businesses and government and the carbon efficiency of expenditure have been analysed to inform mitigation policies. Our findings indicate that final demand in the five largest cities in Australia accounts for more than half of the nation’s CF. City households are responsible for about two thirds of the cities’ CFs; the rest can be attributed to government and business consumption and investment. The city network flows highlight that over half of emissions embodied in imports (EEI to the five cities occur overseas. However, a hierarchy of GHG emissions reveals that overseas regions also outsource emissions to Australian cities such as Perth. We finally discuss the implications of our findings on carbon neutrality, low-carbon city concepts and strategies and allocation of subnational GHG responsibility.

    Water Management in the U.S. Southwest is under increasing scrutiny as many areas endure persistent drought. The impact of these prolonged dry conditions is a product of regional climate and hydrological conditions, but also of a highly engineered water management infrastructure and a complex web of social arrangements whereby water is allocated, shared, exchanged, used, re-used, and finally consumed. We coupled an agent-based model with a regional hydrological model to understand the dynamics in one richly studied and highly populous area: southern Arizona, U.S.A., including metropolitan Phoenix and Tucson. There, multiple management entities representing an array of municipalities and other water providers and customers, including private companies and Native American tribes are enmeshed in a complex legal and economic context in which water is bought, leased, banked, and exchanged in a variety of ways and on multiple temporal and physical scales. A recurrent question in the literature of adaptive management is the impact of management structure on overall system performance. To explore this, we constructed an agent-based model to capture this social complexity, and coupled this with a physical hydrological model that we used to drive the system under a variety of water stress scenarios and to assess the regional impact of the social system's performance. We report the outcomes of ensembles of runs in which varieties of alternative policy constraints and management strategies are considered. We hope to contribute to policy discussions in this area and connected and legislatively similar areas (such as California) as current conditions change and existing legal and policy structures are revised. Additionally, we comment on the challenges of integrating models that ostensibly are in different domains (physical and social) but that independently represent a system in which physical processes and human actions are closely intertwined and difficult to disentangle.

This article aims to propose an architecture that allows cities to provide solutions to interconnect all their elements. The study case focuses in locating and optimized regulation of traffic in cities. However, thanks to the proposed structure and the applied algorithms, the architecture is scalable in size of the sensor network, in functionality or even in the use of resources. A simulation environment that is able to show the operation of the architecture in the same way that a real city would, is presented.

The paper wants to outline which future EU draws for the city, through an integrated and contextual reading of addresses and strategies contained in the last documents, a future often suggested as Smart City. Although the three main documents (Cohesion Policy 2014-2020 of European Community, Digital Agenda for Europe and European Urban Agenda face the issue of the future development of European cities from different points of view, which are respectively cohesion social, ICT and urban dimension, each of them pays particular attention to urban and territorial dimension, identified by the name of Smart City. In other words, the paper aims at drawing the scenario of evolution of Smart Cities that can be delineated through the contextual reading of the three documents. To this end, the paper is divided into three parts: the first part briefly describes the general contents of the three European economic plan tools; the second part illustrates the scenarios for the future of the European city contained in each document; the third part seeks to trace the evolution of the Smart Cities issue developed by the set of the three instruments, in order to provide the framework of European Community for the near future of our cities

    NASA rotor 37 was used as a blind test case for turbomachinery CFD by the Turbomachinery Committee of the IGTI.The rotor is a transonic compressor with a tip speed of 454 m/s(1500ft/s)and a relatively high pressure ratio of 2.1.It was tested in isolation with a circumferentially uniform inlet flow so that the flow through it should be steady apart from and effects of passage to passage geometry variation and mechanical vibration.As such it represents the simplest possible type of test for three-dimensional turbomachinery flow solvers.Howerver,the rotor still presents a real challenge to 3D viscous flow solvers because the shock wave-boudary layer interaction is strong and the effects of viscosity are dominant in determining the flow deviation and hence the pressure ration.Eleven blind solutions were submittewd and in addition a non-blind solution was used to prepare for the exercies.This paper reviews the flow in the test case and the comparisons of the CFD solutions with the test data.Lessons for both the Flow physics in transonic fans and for the application of CFD to such machines are pointed out.

  13. Lessons from dragonfly flight

    Science.gov (United States)

    Wang, Z. Jane

    2005-11-01

    I will describe two lessons we learned from analyzing dragonfly flight using computers and table-top experiments. Part I: The role of drag in insect flight. Airplanes and helicopters are airborne via aerodynamic lift, not drag. However, it is not a priori clear that insects use only lift to fly. We find that dragonfly uses mainly drag to hover, which explains an anomalous factor of four in previous estimates of dragonfly lift coefficients, where drag was assumed to be negligible. Moreover, we show that the use of drag for flight is efficient at insect size. This suggests a re-consideration of the hovering efficiency of flapping flight, which is no longer described by the lift to drag ratio. Part II. Fore-hind wing interaction in dragonfly flight. A distinctive feature of dragonflies is their use of two pairs of wings which are driven by separate direct muscles. Dragonflies can actively modulate the phase delay between fore-hind wings during different maneuver. We compute the Navier-Stokes equation around two wings following the motion measured from our tethered dragonfly experiments, and find an explanation of the advantage of counter-stroking during hovering.

  14. Lessons from independence

    International Nuclear Information System (INIS)

    The recent history of Oryx provides invaluable lessons for those who plan future energy strategies, relates the author of this paper. When Oryx became an independent oil and gas company, its reserves were declining, its stock was selling below asset values, and the price of oil seemed stuck below $15 per barrel. The message from Oryx management to Oryx employees was: We are in charge of our own destiny. We are about to create our own future. Oryx had developed a new, positive corporate culture and the corporate credit required for growth. This paper points to two basic principles that have guided the metamorphosis in Oryx's performance. The first objective was to improve operational efficiency and to identify the right performance indicators to measure this improvement. It states that the most critical performance indicator for an exploration and production company must be replacement and expansion of reserves at a competitive replacement cost. Oryx has cut its finding costs from $12 to $5 per barrel, while the BP acquisition provided proven reserves at a cost of only $4 per barrel. Another performance indicator measures Oryx's standing in the financial markets

  15. Patient safety: lessons learned

    International Nuclear Information System (INIS)

    The traditional approach to patient safety in health care has ranged from reticence to outward denial of serious flaws. This undermines the otherwise remarkable advances in technology and information that have characterized the specialty of medical practice. In addition, lessons learned in industries outside health care, such as in aviation, provide opportunities for improvements that successfully reduce mishaps and errors while maintaining a standard of excellence. This is precisely the call in medicine prompted by the 1999 Institute of Medicine report ''To Err Is Human: Building a Safer Health System.'' However, to effect these changes, key components of a successful safety system must include: (1) communication, (2) a shift from a posture of reliance on human infallibility (hence ''shame and blame'') to checklists that recognize the contribution of the system and account for human limitations, and (3) a cultivation of non-punitive open and/or de-identified/anonymous reporting of safety concerns, including close calls, in addition to adverse events.

    The Blue River Channel Modification project being implemented by the U.S. Army Corps of Engineers (USACE) is intended to provide flood protection within the Blue River valley in the Kansas City, Mo., metropolitan area. In the latest phase of the project, concerns have arisen about preserving the Civil War historic area of Byram's Ford and the associated Big Blue Battlefield while providing flood protection for the Byram's Ford Industrial Park. In 1996, the USACE used a physical model built at the Waterways Experiment Station (WES) in Vicksburg, Miss., to examine the feasibility of a proposed grade control structure (GCS) that would be placed downstream from the historic river crossing of Byram's Ford to provide a subtle transition of flow from the natural channel to the modified channel. The U.S. Geological Survey (USGS), in cooperation with the USACE, modified an existing two-dimensional finite element surface-water model of the river between 63d Street and Blue Parkway (the 'original model'), used the modified model to simulate the existing (as of 2006) unimproved channel and the proposed channel modifications and GCS, and analyzed the results from the simulations and those from the WES physical model. Modifications were made to the original model to create a model that represents existing (2006) conditions between the north end of Swope Park immediately upstream from 63d Street and the upstream limit of channel improvement on the Blue River (the 'model of existing conditions'). The model of existing conditions was calibrated to two measured floods. The model of existing conditions also was modified to create a model that represents conditions along the same reach of the Blue River with proposed channel modifications and the proposed GCS (the 'model of proposed conditions'). The models of existing conditions and proposed conditions were used to simulate the 30-, 50-, and 100-year recurrence floods. The discharge from the calibration flood of May 15, 1990, also

  18. The City at Stake:

    2009-12-01

    Full Text Available Studies of the city have been addressed from many different approaches such as law, political science, art history and public administration, in which the eco-nomic, political and legal status of the city have played a major role. However, a new agenda for conceptualizing the city has emerged, in which the city assumes new roles. By using stakeholder theory as a framework for conceptualizing the city, we argue that the city assumes a political-economic agenda-setting role as well as providing a stage for identity constructions and relational performances for consumers, organizations, the media, politicians and other stakeholders. Stakeholder theory allows us to conceptualize the city as being constituted by stakes and relationships between stakeholders which are approached from three analytical positions (modern, postmodern and hypermodern, respectively, thereby allowing us to grasp different stakes and types of relationships, ranging from functional and contractual relationships to individualized and emotionally driven or more non-committal and fluid forms of relationships. In order to support and illustrate the analytical potentials of our framework for conceptualizing urban living, we introduce a project which aims to turn the city of Aarhus into a CO2-neutral city by the year 2030, entitled Aarhus CO2030. We conclude that applying stakeholder theory to a hyper-complex organization such as a city opens up for a reconceptualization of the city as a web of stakes and stakeholder relations. Stakeholder theory contributes to a nuanced and elaborate understanding of the urban complexity and web of both enforced and voluntary relationships as well as the different types of relationships that characterize urban life.

    These lessons learned are part of a suite of hardware, software, test results, designs, knowledge base, and documentation that comprises the legacy of the Constellation Program. The context, summary information, and lessons learned are presented in a factual format, as known and described at the time. While our opinions might be discernable in the context, we have avoided all but factually sustainable statements. Statements should not be viewed as being either positive or negative; their value lies in what we did and what we learned that is worthy of passing on. The lessons include both "dos" and "don ts." In many cases, one person s "do" can be viewed as another person s "don t"; therefore, we have attempted to capture both perspectives when applicable and useful. While Volume I summarizes the views of those who managed the program, this Volume II encompasses the views at the working level, describing how the program challenges manifested in day-to-day activities. Here we see themes that were perhaps hinted at, but not completely addressed, in Volume I: unintended consequences of policies that worked well at higher levels but lacked proper implementation at the working level; long-term effects of the "generation gap" in human space flight development, the need to demonstrate early successes at the expense of thorough planning, and the consequences of problems and challenges not yet addressed because other problems and challenges were more immediate or manifest. Not all lessons learned have the benefit of being operationally vetted, since the program was cancelled shortly after Preliminary Design Review. We avoid making statements about operational consequences (with the exception of testing and test flights that did occur), but we do attempt to provide insight into how operational thinking influenced design and testing. The lessons have been formatted with a description, along with supporting information, a succinct statement of the lesson learned, and

    2014-06-01

    Full Text Available Sustainability responses must accelerate to avoid major risks to cities. Climate change impact on cities, likely to be significant if global sustainability initiatives are not quickened, is a paramount example of the risk. World wide meetings of city planning practitioners and researchers agree that an urgent agenda is to work together to empower cities and their governments with funds, tools and mentoring to make the responses needed. In the spirit of this urgent agenda, this paper introduces some practical methods for assessing sustainability associated with transport and urban form in our cities. A concept of strategic scans of future scenarios, which underpins the backcasting approach, has been introduced at the 12 th World Conference on Transport Research (WCTR in 2010 and has broken urban and transport planning trend. These strategic scans are based on a sustainability framework, the elements of which provide evidence based drivers of sustainability. The framework culminates in metric visualisations for each of the three pillars of sustainability. The paper details some of the operational aspects of these metrics in the form of environmental sustainability-accessibility space, putting into practice measures of environmental stewardship, social equity, economic efficiency, and the relationship among them. The paper concludes with a call of developing a typology of sustainability performance using the strategic scan methodology to extend the principles of the methodology into a useful tool for city governments and contribute to assembling a daTablease of city forms, transport structures, and their sustainability performances.

  16. Teaching with Internet Telescopes: Some Lessons Learned

    Science.gov (United States)

    Stencel, Robert

    Observational astronomy is often difficult for pre-college students and teachers because: (1) school occurs in daytime and visual observing at night; (2) light pollution hides the stars from students living in cities; (3) few schools have teachers trained to use and maintain astronomy equipment; (4) there is lack of access to expertise when needed; (5) physically disabled students cannot easily access a telescope eypiece. Internet access to computer controlled telescopes with digital cameras can solve many of these difficulties. The Web enables students and teachers to access well-maintained internet-controllable telescopes at dark-site locations and to consult more readily with experts. This paper reports on a three-month pilot project exploring this situation conducted Feb-May 2002 which allowed high school students to access a CCD-equipped accurately-pointing and tracking telescope located in New Mexico controllable over the Web with a user-friendly skymap browser tool. User interest proved phenomenal and user statistics proved diverse. There were distinct lessons learned about how to enhance student participation in the research process.

  17. Lessons of nuclear robot history

    International Nuclear Information System (INIS)

    Severe accidents occurred at Fukushima Daiichi Nuclear Power Station stirred up people's great expectation of nuclear robot's deployment. However unexpected nuclear disaster, especially rupture of reactor building caused by core meltdown and hydrogen explosion, made it quite difficult to introduce nuclear robot under high radiation environment to cease accidents and dispose damaged reactor. Robotics Society of Japan (RSJ) set up committee to look back upon lessons learned from 50 year's past experience of nuclear robot development and summarized 'Lessons of nuclear robot history', which was shown on the home page website of RSJ. This article outlined it with personal comment. History of nuclear robot developed for inspection and maintenance at normal operation and for specific required response at nuclear accidents was reviewed with many examples at home and abroad for TMI, Chernobyl and JCO accidents. Present state of Fukushima accident response robot's introduction and development was also described with some comments on nuclear robot development from academia based on lessons. (T. Tanaka)

    2015-01-01

    Great cities connect people; failed cities isolate people. Despite the fundamental importance of physical, face-to-face social-ties in the functioning of cities, these connectivity networks are not explicitly observed in their entirety. Attempts at estimating them often rely on unrealistic over-simplifications such as the assumption of spatial homogeneity. Here we propose a mathematical model of human interactions in terms of a local strategy of maximising the number of beneficial connections attainable under the constraint of limited individual travelling-time budgets. By incorporating census and openly-available online multi-modal transport data, we are able to characterise the connectivity of geometrically and topologically complex cities. Beyond providing a candidate measure of greatness, this model allows one to quantify and assess the impact of transport developments, population growth, and other infrastructure and demographic changes on a city.

  19. Universities Scale Like Cities

    CERN Document Server

    van Raan, Anthony F J

    2012-01-01

    Recent studies of urban scaling show that important socioeconomic city characteristics such as wealth and innovation capacity exhibit a nonlinear, particularly a power law scaling with population size. These nonlinear effects are common to all cities, with similar power law exponents. These findings mean that the larger the city, the more disproportionally they are places of wealth and innovation. Local properties of cities cause a deviation from the expected behavior as predicted by the power law scaling. In this paper we demonstrate that universities show a similar behavior as cities in the distribution of the gross university income in terms of total number of citations over size in terms of total number of publications. Moreover, the power law exponents for university scaling are comparable to those for urban scaling. We find that deviations from the expected behavior can indeed be explained by specific local properties of universities, particularly the field-specific composition of a university, and its ...

  20. Overview of lessons learnt

    International Nuclear Information System (INIS)

    During the Tarragona International Seminar the participating high-level specialists had very open and fruitful discussion concerning strategic decommissioning issues. The lessons learnt and possible solutions for future work issues can be found below. Although there appears to be a trend towards early dismantling, there seemed to be general agreement that technical solutions support a wide variety of safe decommissioning approaches. Thus, in terms of decommissioning strategy, it appears that no one size fits all. A flexible regulatory approach is needed in order to recognize the changing operational risks and physical conditions of facilities with time, and to optimise their dismantling. The NEA has released a comprehensive study on decommissioning strategies and costs that indicates world-wide progress. According to this report, over 50% of countries with nuclear facilities have a framework of decommissioning requirements and 60% have defined radioactive waste clearance levels. Up to about 70% of the costs of D and D are attributable to dismantling and waste management. The provisions for safety of the D and D process are closely linked to the availability of the necessary funds as and when required. A number of common factors were defined for successful implementation of decommissioning strategies: i.e. safety, technical feasibility of decommissioning options, risk-informed progression of D and D activities as project proceeds, maintenance of competency and corporate memory throughout project, waste management and disposal capability, financing that suits the scope of the project, a well-defined risk-informed and performance-based regulatory process, and establishment of effective communication with local and regional governments and key stakeholders, particularly personnel, at the earliest opportunity before decommissioning.

    The historic cities of Brazil, despite its colonial structure, don't fail to go through transformations that affect contemporary cities, which is the main source of problems, leading to new approaches to urban issues such as mobility and accessibility. The uncontrolled growth of tourism in the historic cities can be considered as a big problem, because at the same time, they have committed to the conservation of its built heritage and demand control of the activities that occur in their areas without harm. Then, a permanent dialogue between conservatives and planners could be accomplished by joining the various sectoral policies. The study of urban mobility in historical sites was in fact the focus of this work because of their peculiarities, such as its specific characteristics of urban structure, morphology and occupation. In fact, the development of tourism in historic centers generates specific demands, such as adaptation to new uses of the houses, intensive movement of people and vehicles, illegal parking, among others. Beyond threatening the city preservation, does not provide mobility and accessibility to tourists, because these cities were not designed for the tourism conditions and needs of contemporary life. Characteristic features of Brazilian baroque cities, such as topography , the narrow streets, narrow or nonexistent sidewalks, steep turns and ramps strong, are not suitable for heavy vehicles, traffic and pedestrian circulation. Thus, studies concerning conservation urban integrated are aimed at an approach to interaction between historic preservation of the environment with the dynamic socio-economic of the local.

    NICU patients are among those potentially most vulnerable to the effects of natural or man-made disaster on a medical center. The published data on evacuations of NICU patients in the setting of disaster are sparse. In October of 2012, New York University Langone Medical Center was evacuated during Hurricane Sandy in the setting of a power outage secondary to a coastal surge. In this setting, 21 neonates were safely evacuated from the medical center's NICU to receiving hospitals within New York City in a span of 4.5 hours. Using data recorded during the evacuation and from staff debriefings, we describe the challenges faced and lessons learned during both the power outage and vertical evacuation. From our experience, we identify several elements that are important to the functioning of an NICU in a disaster or to an evacuation that may be incorporated into future NICU-focused disaster planning. These include a clear command structure, backups (personnel, communication, medical information, and equipment), establishing situational awareness, regional coordination, and flexibility as well as special attention to families and to the availability of neonatal transport resources.

    2015-04-01

    In contemporary town planning protection of urban landscape is a significant issue. It regards especially those cities, where urban structures are the result of ages of evolution and layering of historical development process. Specific panoramas and other strategic views with historic city dominants can be an important part of the cultural heritage and genius loci. Other hand, protection of such expositions introduces limitations for future based city development. Digital Earth observation techniques creates new possibilities for more accurate urban studies, monitoring of urbanization processes and measuring of city landscape parameters. The paper examines possibilities of application of Lidar data and digital 3D-city models for: a) evaluation of strategic city views, b) mapping landscape absorption limits, and c) determination protection zones, where the urbanization and buildings height should be limited. In reference to this goal, the paper introduces a method of computational analysis of the city landscape called Visual Protection Surface (VPS). The method allows to emulate a virtual surface above the city including protection of a selected strategic views. The surface defines maximum height of buildings in such a way, that no new facility can be seen in any of selected views. The research includes also analyses of the quality of simulations according the form and precision of the input data: airborne Lidar / DSM model and more advanced 3D-city models (incl. semantic of the geometry, like in CityGML format). The outcome can be a support for professional planning of tall building development. Application of VPS method have been prepared by a computer program developed by the authors (C++). Simulations were carried out on an example of the city of Dresden.

They decided to make the dreamy city for their residence and then constructed Slavutich city within two years where 24.700 people are living right now by free of charge. There are 11 story apartments and the independent houses with the garden where the people with three children can live. In Fukushima after two years from the bad accident the people are living in the tentative cold houses. There are only the bad news in Fukushima and I strongly insist to make the dreamy city in Fukushima to remember the smiles for the people. (author)

    Climate projections for Leipzig suggest elevated minimum and maximum temperatures as well as more frequent days with high temperatures. Hence, climate change is threatening human well-being and health. People spend the majority of their time indoors. Therefore, indoor temperatures (especially during the night) are of special importance with respect to well-being and health. Indoor air temperature depends on outdoor air temperatures, but is for example modified by type of urban structure, housing area, and may be also influenced by differences in the behavior of the inhabitants. Especially in cities, outdoor air temperatures depend on urban structure e.g. housing density, building arrangement, unpaved areas, types of urban structures, urban green, and other factors. Hence, the questions arise how types of urban structures are related to inner-urban temperature differences and how outdoor air temperatures influence indoor temperatures in dependence on urban housing conditions. This work is a part of a pilot study conducted during the summer 2010 which gathered data from remote sensing, mobile measurements, stationary measurements of air temperatures and relative humidity in areas with different housing structures, and of indoor as well as outdoor temperatures in occupied apartments. Household-survey data reported the subjective perception of heat stress. The study resulted in rather complex relationships between type of housing areas, indoor and outdoor temperatures, morning and evening temperatures, indoor and outdoor temperatures as well as subjective heat perception. Green spaces and types of residential areas are related to air temperatures. More green resulted in lower temperatures. Temperatures have a tendency to increase with increasing story number and are significantly higher in the top floor. An indoor heat island effect corresponding to the outdoor effect could be shown for the homes: Distance to city center is a predicting variable for both outdoor and

    Population culture quality is one of indexes in social attributes of population,the level of intelligence and knowledge,the ability of judging and handling problems in scientific way.It is also one of the important indicators to weigh the comprehensive strength of a country or region.Increasing of population culture quality must be good to accelerate the harmony developing of society,what's more,it will produce a key influence to promoting economy and society.Culture quality is the most important angle in research on spatial structure of population quality and the mach with city scale rather than health quality,mind quality and so on.In the choice of research area,the published papers tend to pick country,province or city,research on county is less.Even though city scale has cleared link with culture quality,the match with city is studied less.This paper took Jiangxi province as the research union,used the data of fifth and sixth nationwide census,utilized some softwares combined with several mathematical methods to measure indicators of culture quality in every place and to investigate its dynamic evolution of spatial pattern from the year of 2000 and 2010.The matched-degree between people culture quality and its city scale was measured by match analysis method.In order to make the result more deeply,this paper analyzed from two aspects:the three regions including north,central and south of Jiangxi,and the prefecture-level city.The diversity of former kind regions especially economy was obvious.The north area took the lead in Jiangxi Province,the central was the old district and played an important role in the history,and the south had distinguishing feature in mineral resources.The study results were as follows.(1) The space was based on wriggle aggregation,and the phenomenon that high-quality population gathered in the north of Jiangxi had not changed.(2)The condition of culture-city offset was improved from the larger regional disparities to balanced

    1998-06-01

    Systematic evaluation of a project, product or other successes, and failures, is an important method for improving the performance of a company, as well as that of an individual. One should evaluate and determine if lessons learned can be applied to the systems and procedures being used in the company. Even if the company does not have to adjust its strategies, procedures, portfolio or systems as a result of lessons it has learned, there may be pointers to communicate to staff. It is easy for many aspects of a system to become outdated, particularly in an organization that is growing or changing rapidly. It is therefore generally appropriate to evaluate the company's regulatory compliance, toxicology compliance, clinical auditing practices and other appropriate systems on an annual or biannual basis. Most lessons of success or failure are specific to a single situation because of the combination of people, drug, competition, priorities and many other factors involved, and cannot be extrapolated to other situations. Some general lessons and principles are presented that will facilitate drug discovery, development and marketing. PMID:15616644

  17. Evolutionary lessons from California plant phylogeography.

    Science.gov (United States)

    Sork, Victoria L; Gugger, Paul F; Chen, Jin-Ming; Werth, Silke

    2016-07-19

    Phylogeography documents the spatial distribution of genetic lineages that result from demographic processes, such as population expansion, population contraction, and gene movement, shaped by climate fluctuations and the physical landscape. Because most phylogeographic studies have used neutral markers, the role of selection may have been undervalued. In this paper, we contend that plants provide a useful evolutionary lesson about the impact of selection on spatial patterns of neutral genetic variation, when the environment affects which individuals can colonize new sites, and on adaptive genetic variation, when environmental heterogeneity creates divergence at specific loci underlying local adaptation. Specifically, we discuss five characteristics found in plants that intensify the impact of selection: sessile growth form, high reproductive output, leptokurtic dispersal, isolation by environment, and the potential to evolve longevity. Collectively, these traits exacerbate the impact of environment on movement between populations and local selection pressures-both of which influence phylogeographic structure. We illustrate how these unique traits shape these processes with case studies of the California endemic oak, Quercus lobata, and the western North American lichen, Ramalina menziesii Obviously, the lessons we learn from plant traits are not unique to plants, but they highlight the need for future animal, plant, and microbe studies to incorporate its impact. Modern tools that generate genome-wide sequence data are now allowing us to decipher how evolutionary processes affect the spatial distribution of different kinds of genes and also to better model future spatial distribution of species in response to climate change.

  18. Lessons learned related to packaging and transportation

    International Nuclear Information System (INIS)

    The use of lessons learned as a tool for learning from past experiences is well established, especially by many organizations within the nuclear industry. Every person has, at some time, used the principles of lessons learned to adopt good work practices based on their own experiences or the experiences of others. Lessons learned can also help to avoid the recurrence of adverse practices, which is often an area that most lessons-learned programs tend to focus on. This paper will discuss how lessons learned relate to packaging and transportation issues and events experienced at Department of Energy (DOE) facilities. It will also discuss the role performed by the Office of Nuclear and Facility Safety's Office of Operating Experience Analysis and Feedback in disseminating lessons learned and operating experience feedback to the DOE complex. The central concept of lessons learned is that any organization should be able to learn from its own experiences and events. In addition, organizations should implement methodologies to scan external environments for lessons learned, to analyze and determine the relevance of lessons learned, and to bring about the necessary changes learned from these experiences. With increased concerns toward facility safety, the importance of utilizing the lessons-learned principles and the establishment of lessons-learned programs can not be overstated

    Great cities connect people; failed cities isolate people. Despite the fundamental importance of physical, face-to-face social ties in the functioning of cities, these connectivity networks are not explicitly observed in their entirety. Attempts at estimating them often rely on unrealistic over-simplifications such as the assumption of spatial homogeneity. Here we propose a mathematical model of human interactions in terms of a local strategy of maximizing the number of beneficial connections attainable under the constraint of limited individual travelling-time budgets. By incorporating census and openly available online multi-modal transport data, we are able to characterize the connectivity of geometrically and topologically complex cities. Beyond providing a candidate measure of greatness, this model allows one to quantify and assess the impact of transport developments, population growth, and other infrastructure and demographic changes on a city. Supported by validations of gross domestic product and human immunodeficiency virus infection rates across US metropolitan areas, we illustrate the effect of changes in local and city-wide connectivities by considering the economic impact of two contemporary inter- and intra-city transport developments in the UK: High Speed 2 and London Crossrail. This derivation of the model suggests that the scaling of different urban indicators with population size has an explicitly mechanistic origin. PMID:26179988

    2002-11-01

    Full Text Available First year dental students at The University of Texas Dental Branch at Houston (Dental Branch are required to take a basic biochemistry course. To facilitate learning and allow student self-assessment of their progress, WWW-based lessons covering intermediary metabolism were developed as a supplement to traditional lectures. Lesson design combined text, graphics, and animations and included learner control, links to other learning resources, and practice exercises and exams with immediate feedback. Results from an on-line questionnaire completed by students in two different classes showed that they completed 50% of the lessons and spent an average of 4 hrs. on-line. A majority of the students either agreed or strongly agreed that practice exercises were helpful, that the ability to control the pace of the lessons was important, that the lesson structure and presentation was easy to follow, that the illustrations, animations, and hyperlinks were helpful, and that the lessons were effective as a review. The very positive response to the WWW-based lessons indicates the usefulness of this approach as a study aid for dental students.

    NASA policy requires each Program or Project to develop a plan for how they will address Lessons Learned. Projects have the flexibility to determine how best to promote and implement lessons learned. A large project might budget for a lessons learned position to coordinate elicitation, documentation and archival of the project lessons. The lessons learned process crosses all NASA Centers and includes the contactor community. o The Office of The Chief Engineer at NASA Headquarters in Washington D.C., is the overall process owner, and field locations manage the local implementation. One tool used to transfer knowledge between program and projects is the Lessons Learned Information System (LLIS). Most lessons come from NASA in partnership with support contractors. A search for lessons that might impact a new design is often performed by a contractor team member. Knowledge is not found with only one person, one project team, or one organization. Sometimes, another project team, or person, knows something that can help your project or your task. Knowledge sharing is an everyday activity at the Kennedy Space Center through storytelling, Kennedy Engineering Academy presentations and through searching the Lessons Learned Information system. o Project teams search the lessons repository to ensure the best possible results are delivered. o The ideas from the past are not always directly applicable but usually spark new ideas and innovations. Teams have a great responsibility to collect and disseminate these lessons so that they are shared with future generations of space systems designers. o Leaders should set a goal for themselves to host a set numbers of lesson learned events each year and do more to promote multiple methods of lessons learned activities. o High performing employees are expected to share their lessons, however formal knowledge sharing presentation are not the norm for many employees.

    As manned space exploration takes on the task of traveling beyond low Earth orbit, many problems arise that must be solved in order to make the journey possible. One major task is protecting humans from the harsh space environment. The current method of protecting astronauts during Extravehicular Activity (EVA) is through use of the specially designed Extravehicular Mobility Unit (EMU). As more rigorous EVA conditions need to be endured at new destinations, the suit will need to be tailored and improved in order to accommodate the astronaut. The Objective behind the EMU Lessons Learned Database(LLD) is to be able to create a tool which will assist in the development of next-generation EMUs, along with maintenance and improvement of the current EMU, by compiling data from Failure Investigation and Analysis Reports (FIARs) which have information on past suit failures. FIARs use a system of codes that give more information on the aspects of the failure, but if one is unfamiliar with the EMU they will be unable to decipher the information. A goal of the EMU LLD is to not only compile the information, but to present it in a user-friendly, organized, searchable database accessible to all familiarity levels with the EMU; both newcomers and veterans alike. The EMU LLD originally started as an Excel database, which allowed easy navigation and analysis of the data through pivot charts. Creating an entry requires access to the Problem Reporting And Corrective Action database (PRACA), which contains the original FIAR data for all hardware. FIAR data are then transferred to, defined, and formatted in the LLD. Work is being done to create a web-based version of the LLD in order to increase accessibility to all of Johnson Space Center (JSC), which includes converting entries from Excel to the HTML format. FIARs related to the EMU have been completed in the Excel version, and now focus has shifted to expanding FIAR data in the LLD to include EVA tools and support hardware such as

    2015-06-01

    There is a substantial and growing burden of premature mortality caused by non-communicable diseases (NCDs) globally. This paper evaluates the preventive efforts of the WHO European Healthy Cities Network during its fifth phase (2009-13), specifically for four behavioural risk factors (tobacco use, alcohol abuse, unhealthy diet and physical inactivity). Drawing on case studies, questionnaire responses and other materials, it notes which cities were involved, what worked and did not, the triggers for action, challenges met and lessons learnt. Few cities appeared to have taken comprehensive approaches to NCD prevention across multiple risk factors, or have combined population- and individual-level interventions. Work on healthy food and diet predominantly focused on children in educational or care settings, and few cities appeared to take a comprehensive approach to tackling obesity. Partnerships were a strong feature for all the NCD risk factor work, and were frequently extensive, being most diverse for the Healthy Diet and Food work. There were strong examples of engagement with communities, also involved in co-designing and shaping projects. Equity also featured strongly and there were multiple examples of how attention had been paid to the social determinants of health. There was evidence that cities continue to be significant innovative forces within their countries and drivers of change, and the mutual dependency of the national and local levels was highlighted. Interventions to promote physical activity have shifted focus from specific events and projects to being more integrated with other policy areas and based on intersectoral collaboration.

  19. An analytical quality framework for learning cities and regions

    Science.gov (United States)

    Preisinger-Kleine, Randolph

    2013-09-01

    There is broad agreement that innovation, knowledge and learning have become the main source of wealth, employment and economic development of cities, regions and nations. Over the past two decades, the number of European cities and regions which label themselves as "learning city" or "learning region" has constantly grown. However, there are also pitfalls and constraints which not only hinder them in unlocking their full potential, but also significantly narrow their effects and their wider impact on society. Most prominently, learning cities and regions manifest serious difficulties in rendering transparent the surplus value they generate, which is vital for attracting investment into lifelong learning. While evaluation and quality management are still perceived as being a bureaucratic necessity rather than a lesson one could learn from or an investment in the future, it is also true that without evaluation and quality assurance local networks do not have the means to examine their strengths and weaknesses. In order to design strategies to maximise the strengths and effectively address the weaknesses it is necessary to understand the factors that contribute to success and those that pose challenges. This article proposes an analytical quality framework which is generic and can be used to promote a culture of quality in learning cities and regions. The proposed framework builds on the findings and results of the R3L+ project, part-funded by the European Commission under the Grundtvig (adult education) strand of the Lifelong Learning programme 2007-2013.

  20. Analyzing students' attitudes towards science during inquiry-based lessons

    Science.gov (United States)

    Kostenbader, Tracy C.

    Due to the logistics of guided-inquiry lesson, students learn to problem solve and develop critical thinking skills. This mixed-methods study analyzed the students' attitudes towards science during inquiry lessons. My quantitative results from a repeated measures survey showed no significant difference between student attitudes when taught with either structured-inquiry or guided-inquiry lessons. The qualitative results analyzed through a constant-comparative method did show that students generate positive interest, critical thinking and low level stress during guided-inquiry lessons. The qualitative research also gave insight into a teacher's transition to guided-inquiry. This study showed that with my students, their attitudes did not change during this transition according to the qualitative data however, the qualitative data did how high levels of excitement. The results imply that students like guided-inquiry laboratories, even though they require more work, just as much as they like traditional laboratories with less work and less opportunity for creativity.

    Full Text Available On a worldwide scale, cities and regions must tackle the challenges set by the radical change in our society and in our economy, aiming to develop effective public policies and boost their managerial, evaluation and planning skills. Anyway, it is essential to put a new idea of city at the centre of the smart strategies in order to bring policies back to their former central position, since technologies alone cannot generate welfare and prosperity. Local leadership, integrated planning and a rich social fabric go hand in hand, the social capital being able to produce an added value for the cities. We are exactly in a new phase of urban growth centred on the economy of services characterized by widespread digital technologies and new innovative organization patterns, which encourage the participation in the civic policy processes through the realization of structures to share information and data so as to define intervention policies. The most recent studies and trials about innovation and competitiveness, such as the examples illustrated in the present work (Amsterdam, Paredes, Aarhus and Gent show a growing interest in measuring the relationship between innovation and economic growth at various territorial levels, key factors in conceiving inclusive smart strategies, linked to principles of sustainability and territorial cohesion, and building smarter cities. In the light of these remarks, the article is divided into three parts: the first part is focussed on the above-mentioned central issues of the international debate; the second part examines four significant European initiatives; the third part draws preliminary conclusions and directions for further research.

  3. Lessons from Rwanda

    Full Text Available Before a recent visit to Rwanda, all that the country held for me, as with most people, was the spectre of genocide, war, poverty and starving children. My brief visit to the city of Kigali challenged my widely held assumptions about the country. Kigali was the epicenter of the genocide in Rwanda, where about one million people experienced murderous tyranny within a space of 100 days, that wreaked havoc upon the country and left millions of people with untold losses and emotional scars. Rwanda is, indeed, an amazing example of a country rising from the ashes. My first encounter was on the Air Rwanda flight, where the in-flight magazine warns those entering the country to leave their plastic bags behind; that no person would be allowed to pass through immigration and customs with plastic bags and wrappings. A plastic bag free country is one of Rwanda’s contributions to environmental conservation and saving the earth. And of course in stores, its paper bags all the way!

  16. Improving the City environment

    International Nuclear Information System (INIS)

    All around the world cities are under severe environmental pressure. Water supplies, traffic congestion, air pollution, noise and waste disposal cause very similar problems in cities that are otherwise quite diverse. And attempts to improve conditions usually run into a range of difficulties. Indeed, environmental problems often persist for years before governments -national, regional and local- make any major effort to address them. 6 refs

    This paper looks at the urban development of transition countries in 1991–2010, primarily focusing on the last decade. Cities in transition face a unique set of challenges that came forth due to interplay of the legacy of socialist urban policies and the transition to the market economy. The socialist urban policies restrained growth of the largest cities and distorted the spatial equilibrium towards more uniform distribution of urban population. The transition to the market economy reduces d...

We distinguish between three potential explanations of why firms are willing to pay urban workers more: (1) the urban wage premium is spurious and is the result of omitted ability measures, (2) the urban wage premium works because cities enhance productivity and (3) the urban wage premium is the result of faster skill accumulation in cities. Using a combination of standard regressions, individual...

  4. Hierarchical Scaling in Systems of Natural Cities

    CERN Document Server

    Chen, Yanguang

    2016-01-01

    Hierarchies can be modeled by a set of exponential functions, from which we can derive a set of power laws indicative of scaling. These scaling laws are followed by many natural and social phenomena such as cities, earthquakes, and rivers. This paper is devoted to revealing the scaling patterns in systems of natural cities by reconstructing the hierarchy with cascade structure. The cities of America, Britain, France, and Germany are taken as examples to make empirical analyses. The hierarchical scaling relations can be well fitted to the data points within the scaling ranges of the size and area of the natural cities. The size-number and area-number scaling exponents are close to 1, and the allometric scaling exponent is slightly less than 1. The results suggest that natural cities follow hierarchical scaling laws and hierarchical conservation law. Zipf's law proved to be one of the indications of the hierarchical scaling, and the primate law of city-size distribution represents a local pattern and can be mer...

  7. From mobility patterns to scaling in cities

    CERN Document Server

    Louf, Rémi

    2014-01-01

    The recent availability of data for cities has allowed scientists to exhibit scalings which present themselves in the form of a power-law dependence with population of various socio-economical (GDP, gasoline consumption, number of patents, etc.) and structural indicators (urbanized land area, lane miles of the road network, etc.). Despite numerous attempts, the gap between empirical regularities and the theoretical understanding of cities has not yet been bridged. We propose here a dynamical, stochastic theory of urban growth which accounts for the observed scalings and we confirm these results on US and OECD empirical data. Our results suggest that the key needed to decipher most of cities' complexity is the spatial structure of the mobility pattern, controlled by congestion. In particular, we show that the dependence with population size of the total number of miles driven daily, the total length of the road network, the total traffic delay, the total consumption of gasoline, the quantity of $CO_2$ emitted ...

    CERN Document Server

    Semblat, Jean-François; Guéguen, Philippe; Bard, Pierre-Yves; Duval, Anne Marie

    2009-01-01

    The analysis of seismic site effects generally disregards the influence of surface structures on the free field motion in densely urbanized areas. This paper aims at investigating this particular problem called site-city interaction especially by comparison to the "free-field" amplification process. Several evidences (experimental, analytical, numerical) of the site-city interaction phenomenon have been given in previous work (Gu\\'eguen, Bard, Semblat 2000). The influence of site city-interaction could be large for structures having eigenfrequencies close to that of the surface soil layers. Furthermore, the density of structures is also an important governing parameter of the problem. Considering a specific site (Nice, France) where site-city interaction is supposed to be significant, we start from detailed experimental and numerical studies of seismic site effects giving both amplification levels and occuring frequencies, as well as the location of the maximum amplification areas. The influence of site-city ...

    Southern California has a history of major earthquakes and also has one of the largest metropolitan areas in the United States. The 1994 Northridge Earthquake challenged the industrial facilities and lifetime infrastructure in the northern Los Angeles (LA) area. Lawrence Livermore National Laboratory (LLNL) sent a team of engineers to conduct an earthquake damage investigation in the Northridge area, on a project funded jointly by the United States Nuclear Regulatory Commission (USNRC) and the United States Department of Energy (USDOE). Many of the structures, systems, and components (SSCs) and lifelines that suffered damage are similar to those found in nuclear power plants and in USDOE facilities. Lessons learned from these experiences can have some applicability at commercial nuclear power plants.

  11. Lessons learned from advanced practice nursing payment.

    Sullivan-Marx, Eileen M

    2008-05-01

    For more than 25 years, advanced practice nurses have been incrementally included as a part of the health care financing structure. Following physician payment revisions at the federal level, advanced practice nurses were overtly recognized as Medicare providers and have participated in the establishment of current procedural terminology codes and the subsequent relative work values associated with payment. Success in this regard has been the result of business, political, and policy savvy that has important lessons for moving forward in any health care restructuring for both nurses and advanced practice nurses. Principles of valuing nurse work, time, and intensity in the Resource-Based Relative Value Scale are discussed with implications for future opportunities of measuring nursing work and any potential relationship to quality outcomes of care.

    Institute of Scientific and Technical Information of China (English)

    Liu; Dan; Hua; Chen

    2015-01-01

    In the twenty-first century, the population in China will be increasingly urbanized – focusing the sustainability challenge on cities and raising new challenges to address the urban resilience capacity. During the past two decades, China’s urban policies are state institution-directed, growth-oriented, and land-based, imposing unprecedented challenges on sustainability. Strengthening the capacity of cities to manage resilience appears to be a key factor for cities to effectively pursue sustainable development. The aim of this paper is to explore strategic planning approaches for creating resilient cities in China through a study on Hangzhou City in an integrated framework. Firstly, the paper gives a systematic insight into the structure of Hangzhou City. Secondly, the development trajectory of the urban system is analyzed to understand how the past has shaped the present and to get a broader perspective on its evolution. Thirdly, scenario planning is conducted to explore the adaptive capacity of Hangzhou City under different future conditions. At last, having analyzed the past, present, and future of the urban system, the paper discusses the strategies for resilient planning, which helps to identify factors and trends that might enhance or inhabit the adaptability.

    Full Text Available Including in a novel information about relief, climate, vegetation, fauna and various aspects of socio-economic life can make literature a real source of geographical information. Using realistic literary works in Geography lessons has multiple benefits, which are not limited only to geographical knowledge. In this paper there are some fragments from literature, suggestions of activities about how to integrate the fragments during Geography lessons and the results of these activities. The activities are from fifth to twelfth grade, passing through a first example of water pollution resulting from a Hercules labour, through the lyricism of the aurora borealis description, through the dramatic life of a refugee from Darfur, through the Dobrudgea winter landscape, through the grey urban landscape of Bucharest in the 90s and so on. Students were put into learning situations that stimulated their creativity, developed communication competencies and enriched their general knowledge.

    International Nuclear Information System (INIS)

    The City of Hamilton has launched an extensive energy planning exercise that examines the possibility of steep increases in oil and natural gas prices. This report examined and illustrated the issue of oil and gas price points. The report also examined and presented the city's role in an era of energy constraints, focusing on the city's transit system and its vehicle fleet. In addition, in response to City Council's direction, the report presented the aerotropolis proposal and discussed freight transport issues. Specific topics of discussion included oil and natural gas prospects; prospects for high oil and natural gas prices; impacts of fuel price increases; strategic planning objectives for energy constraints; reducing energy use by Hamilton's transport and in buildings; and land-use planning for energy constraints. Energy production opportunities involve the use of solar energy; wind energy; deep lake water cooling (DLWC); hydro-electric power; energy from waste; biogas production; district energy; and local food production. Economic and social development through preparing for energy constraints and matters raised by city council were also presented. The report also demonstrated how an energy-based strategy could be paid for and its components approved. The next steps for Hamilton were also identified. refs., tabs., figs

    Science.gov (United States)

    2002-01-01

    This image of Earth's city lights was created with data from the Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS). Originally designed to view clouds by moonlight, the OLS is also used to map the locations of permanent lights on the Earth's surface. The brightest areas of the Earth are the most urbanized, but not necessarily the most populated. (Compare western Europe with China and India.) Cities tend to grow along coastlines and transportation networks. Even without the underlying map, the outlines of many continents would still be visible. The United States interstate highway system appears as a lattice connecting the brighter dots of city centers. In Russia, the Trans-Siberian railroad is a thin line stretching from Moscow through the center of Asia to Vladivostok. The Nile River, from the Aswan Dam to the Mediterranean Sea, is another bright thread through an otherwise dark region. Even more than 100 years after the invention of the electric light, some regions remain thinly populated and unlit. Antarctica is entirely dark. The interior jungles of Africa and South America are mostly dark, but lights are beginning to appear there.

  7. Universities scale like cities.

    Directory of Open Access Journals (Sweden)

    Anthony F J van Raan

    Full Text Available Recent studies of urban scaling show that important socioeconomic city characteristics such as wealth and innovation capacity exhibit a nonlinear, particularly a power law scaling with population size. These nonlinear effects are common to all cities, with similar power law exponents. These findings mean that the larger the city, the more disproportionally they are places of wealth and innovation. Local properties of cities cause a deviation from the expected behavior as predicted by the power law scaling. In this paper we demonstrate that universities show a similar behavior as cities in the distribution of the 'gross university income' in terms of total number of citations over 'size' in terms of total number of publications. Moreover, the power law exponents for university scaling are comparable to those for urban scaling. We find that deviations from the expected behavior can indeed be explained by specific local properties of universities, particularly the field-specific composition of a university, and its quality in terms of field-normalized citation impact. By studying both the set of the 500 largest universities worldwide and a specific subset of these 500 universities--the top-100 European universities--we are also able to distinguish between properties of universities with as well as without selection of one specific local property, the quality of a university in terms of its average field-normalized citation impact. It also reveals an interesting observation concerning the working of a crucial property in networked systems, preferential attachment.

  8. Lessons from the Asian Crisis

    This paper provides an asymmetric information analysis of the recent East Asian crisis. It then outlines several lessons from this crisis. First, there is a strong rationale for an international lender of last resort. Second, without appropriate conditionality for this lending, the moral hazard created by operation of an international lender of last resort can promote financial instability. Third, although capital flows did contribute to the crisis, they are a symptom rather than an underlyin...

  11. Lessons learned by southern states in designating alternative routes

    International Nuclear Information System (INIS)

    The purpose of this report is to discuss the ''lessons learned'' by the five states within the southem region that have designated alternative or preferred routes under the regulations of the Department of Transportation (DOT) established for the transportation of radioactive materials. The document was prepared by reviewing applicable federal laws and regulations, examining state reports and documents and contacting state officials and routing agencies involved in making routing decisions. In undertaking this project, the Southern States Energy Board hopes to reveal the process used by states that have designated alternative routes and thereby share their experiences (i.e., lessons learned) with other southern states that have yet to make designations. Under DOT regulations (49 CFR 177.826), carriers of highway route controlled quantities of radioactive materials (which include spent nuclear fuel and high-level waste) must use preferred routes selected to reduce time in transit. Such preferred routes consist of (1) an interstate system highway with use of an interstate system bypass or beltway around cities when available, and (2) alternate routes selected by a ''state routing agency.''

  12. Taenia solium Cysticercosis--The lessons of history.

    Science.gov (United States)

    Del Brutto, Oscar H; García, Héctor H

    2015-12-15

    Human taeniasis as well as porcine and human cysticercosis--caused by the pork tapeworm Taenia solium--are ancient diseases. The fact that pigs were considered impure in the ancient Greece and that the Koran prohibited the consumption of pork, were likely related to the knowledge that cysticercosis may affect swine. Evidence suggests that human cysticercosis was also present in the ancient Egypt and Rome. During the Renaissance, the causative agent was properly identified and human cases were recognized. Confirmation that both taeniasis and cysticercosis were caused by the same parasite was provided during the 19th Century by German pathologists. During the 20th Century, bouts of human cysticercosis in non-endemic regions left us valuable lessons on the mechanisms of disease acquisition and spread. These included a large series of neurocysticercosis cases in the United Kingdom that occurred after the return of troops stationed in India (which demonstrated that symptoms may occur years after infection), the epidemic of cysticercosis-related epilepsy in the Ekari people of Papua New Guinea occurring after the gift of pigs with cysticercosis received from Indonesia (demonstrating the fast establishment of endemic transmission and the impact of cysticercosis in epilepsy frequency), and the occurrence of neurocysticercosis among members of an Orthodox Jewish community of New York City, related to Latin American Taenia carriers working in their houses (highlighting the fact that cysticercosis transmission do not require the presence of infected pigs). These lessons of history have significantly contributed to our current knowledge on this disease. PMID:26320098

  13. The lesson of quantum theory

    International Nuclear Information System (INIS)

    The concepts of quantal states and complementarity introduced by Niels Bohr in an intuitive though definitive manner more than a generation ago have come to form cornerstones in our description of nature. The Centenary Symposium celebrating Niels Bohr pays tribute to his work which gave birth to contemporary physics and nourished related fields of knowledge. The book is divided into three parts. Part One consists of two communications to the Royal Danish Academy of Sciences and Letters in memory of Niels Bohr. Part Two containing the main theme of the proceedings is divided into three sections. The title of the first, The Lesson of Quantum Theory, is an expression often used by Niels Bohr as time and again he endeavoured an ever deeper analysis of this lesson and its succinct formulation. For Bohr the lesson of quantum theory went beyond physics encompassing not only the natural sciences but all human conceptions. Thus the second section, Unity of Knowledge, conveys the progress in neighbouring disciplines in which Bohr took a particular interest. The last section, Niels Bohr, is dedicated to his personality, his activities, and his world of thought. Part three renders speeches and anecdotes presented during the evening gathering at Ny Carlsberg Glyptoteket on Niels Bohr's one hundredth birthday. (Auth.)

  14. Spent Fuel Storage Operation - Lessons Learned

    International Nuclear Information System (INIS)

    Experience gained in planning, constructing, licensing, operating, managing and modifying spent fuel storage facilities in some Member States now exceeds 50 years. Continual improvement is only achieved through post-project review and ongoing evaluation of operations and processes. This publication is aimed at collating and sharing lessons learned. Hopefully, the information provided will assist Member States that already have a developed storage capability and also those considering development of a spent nuclear fuel storage capability in making informed decisions when managing their spent nuclear fuel. This publication is expected to complement the ongoing Coordinated Research Project on Spent Fuel Performance Assessment and Research (SPAR-III); the scope of which prioritizes facility operational practices in lieu of fuel and structural components behaviour over extended durations. The origins of the current publication stem from a consultants meeting held on 10-12 December 2007 in Vienna, with three participants from the IAEA, Slovenia and USA, where an initial questionnaire on spent fuel storage was formulated (Annex I). The resultant questionnaire was circulated to participants of a technical meeting, Spent Fuel Storage Operations - Lessons Learned. The technical meeting was held in Vienna on 13-16 October 2008, and sixteen participants from ten countries attended. A consultants meeting took place on 18-20 May 2009 in Vienna, with five participants from the IAEA, Slovenia, UK and USA. The participants reviewed the completed questionnaires and produced an initial draft of this publication. A third consultants meeting took place on 9-11 March 2010, which six participants from Canada, Hungary, IAEA, Slovenia and the USA attended. The meeting formulated a second questionnaire (Annex II) as a mechanism for gaining further input for this publication. A final consultants meeting was arranged on 20-22 June 2011 in Vienna.

    Cheng, Hefa; Hu, Yuanan

    2010-01-01

    With the rapid urbanization in China, the country faces significant challenges in sustainable urban development and actively explores novel ways to expand urban areas while conserving natural resources. Radical changes in city planning are being made to switch to sustainable development, with new cities being designed to be ecologically friendly guided by principles like carbon neutrality and self-sufficiency. This paper introduces the development of the Dongtan eco-city project on Chongming Island, Shanghai and describes how it addresses issues including energy, water, waste, transportation, ecosystem, and social and economic development in its design. The lessons and challenges of eco-city development based on the Dongtan experience are also discussed. If the vision of a zero-carbon emissions sustainable city is successfully realized, Dongtan will serve as a model for developing similar cities across China and the rest of the developing world. Currently, the development of this project is behind schedule and whether the eco-city plan will materialize or not is in question. Even though the project remains mostly on the drawing boards, the planning and preliminary development of Dongtan eco-city have generated significant enthusiasm for green buildings and influenced plans for other sustainable urban development projects in China.

    Ultrafine particles (UFPs; diameter less than 100 nm) are ubiquitous in urban air, and an acknowledged risk to human health. Globally, the major source for urban outdoor UFP concentrations is motor traffic. Ongoing trends towards urbanisation and expansion of road traffic are anticipated to further increase population exposure to UFPs. Numerous experimental studies have characterised UFPs in individual cities, but an integrated evaluation of emissions and population exposure is still lacking. Our analysis suggests that the average exposure to outdoor UFPs in Asian cities is about four-times larger than that in European cities but impacts on human health are largely unknown. This article reviews some fundamental drivers of UFP emissions and dispersion, and highlights unresolved challenges, as well as recommendations to ensure sustainable urban development whilst minimising any possible adverse health impacts.

  17. Reproducing in cities.

    Science.gov (United States)

    Mace, Ruth

    2008-02-01

    Reproducing in cities has always been costly, leading to lower fertility (that is, lower birth rates) in urban than in rural areas. Historically, although cities provided job opportunities, initially residents incurred the penalty of higher infant mortality, but as mortality rates fell at the end of the 19th century, European birth rates began to plummet. Fertility decline in Africa only started recently and has been dramatic in some cities. Here it is argued that both historical and evolutionary demographers are interpreting fertility declines across the globe in terms of the relative costs of child rearing, which increase to allow children to outcompete their peers. Now largely free from the fear of early death, postindustrial societies may create an environment that generates runaway parental investment, which will continue to drive fertility ever lower.

    2010-02-01

    The New York City Police Department (NYPD) has made enforcement of laws against disorder and quality-of-life offenses a central part of their policing strategy. Concomitantly, New York City (NYC) experienced a renaissance in orderliness, cleanliness, tourism, real estate value, and crime reduction, although other problems such as poverty, unemployment, drug abuse, racial tensions and homelessness persist. This paper examines quality-of-life policing practices in NYC, describes the philosophical underpinnings, explores the critical response to the program and presents lessons of potential relevance to other policing organizations in the U.S. and around the world.

  20. Urban Energy Generation and the Role of Cities

    DEFF Research Database (Denmark)

    Groth, Niels Boje; Fertner, Christian; Große, Juliane

    Although a major part of energy consumption happens in cities, contemporary energy generation is less obviously connected to the urban structure. Energy based on fossil fuels and consumed in transportation is produced at global scale; energy for electricity is usually distributed through a national...... still feeding into the grid. Furthermore, through the ongoing liberalisation of energy markets and a subsequent change in the organisation structure of energy providers towards larger co-operations as well as the development of new technologies as ‘smart grid’-solutions, local authorities seem to lose...... cities can be twofold: (1) cities as producers and (2) cities as enablers or promoters. Furthermore, energy production (renewable or not) has to happen somewhere, potentially also in the city where consumption takes place, and is related to specific spatial conditions. We review the contemporary options...

    2012-01-01

    We compare the structural properties of the street networks of ten different European cities using their primal representation. We investigate the properties of the geometry of the networks and a set of centrality measures highlighting differences and similarities among cases. In particular, we found that cities share structural similarities due to their quasi planarity but that there are also several distinctive geometrical proprieties. A Principal Component Analysis is also performed on the distributions of centralities and their respective moments, which is used to find distinctive characteristics by which we can classify cities into families. We believe that, beyond the improvement of the empirical knowledge on streets network proprieties, our findings can open new perspectives in the scientific relation between city planning and complex networks, stimulating the debate on the effectiveness of the set of knowledge that statistical physics can contribute for city planning and urban morphology studies.

Ranking of the Hungarian cities and counties are represented on their „Green Cities Index” and „Green Counties Index” values. According to the methodology shown in Part 1, cities and counties were grouped on different classification techniques and efficacy of the classification was analysed. However, they did not give acceptable results either for the cities, or for the counties. According to the parameters of the here mentioned three algorithms, reasonable structures were not found in any clustering. Clusters received applying algorithm fanny, though having weak structure, indicate large and definite regions in Hungary, which can be circumscribed by clear geographical objects.

    2014-09-01

    Full Text Available China is the epicenter of the global tobacco epidemic. China grows more tobacco, produces more cigarettes, makes more profits from tobacco and has more smokers than any other nation in the world. Approximately one million smokers in China die annually from diseases caused by smoking, and this estimate is expected to reach over two million by 2020. China cities have a unique opportunity and role to play in leading the tobacco control charge from the “bottom up”. The Emory Global Health Institute—China Tobacco Control Partnership supported 17 cities to establish tobacco control programs aimed at changing social norms for tobacco use. Program assessments showed the Tobacco Free Cities grantees’ progress in establishing tobacco control policies and raising public awareness through policies, programs and education activities have varied from modest to substantial. Lessons learned included the need for training and tailored technical support to build staff capacity and the importance of government and organizational support for tobacco control. Tobacco control, particularly in China, is complex, but the potential for significant public health impact is unparalleled. Cities have a critical role to play in changing social norms of tobacco use, and may be the driving force for social norm change related to tobacco use in China.

  6. Can BRT solve the transport crisis in Dhaka city?

    2007-07-01

    Transport situation in Dhaka City, the capital of Bangladesh, has recently reached in a crisis situation - road congestion and emissions is spreading and the transport system is unable to meet the demands. Because of unavailable and overcrowded bus service, the cheapest form of public transport, the high dependence on walking and rickshaw in a city of 12 million is a symptom of inefficient and ineffective transport systems and operations. The expected addition of another 12 million people over the next 15 years will make the transport conditions almost unbearable, unless urgent measures are taken. So, policy measure for transport of the city should be directed towards tackling the large amount of travel demand and reducing congestion. Based on the secondary information, this paper has been initiated to come up with some guidelines for providing sufficient transport supply. For this purpose, successful bus rapid transit (BRT) systems of developing countries especially Bogota and Curitiba have been studied to gain lessons for the possibility of BRT in Dhaka. The study found that BRT is the most suitable form of public transport for Dhaka City to tackle the public transport crisis.

  7. Project Wish: The Emerald City, phase 3

    Science.gov (United States)

    1992-01-01

    Phase 3 of Project Wish saw the evolution of the Emerald City (E-City) from a collection of specialized independent analyses and ideas to a working structural design integrated with major support systems and analyses. Emphasis was placed on comparing and contrasting the closed and open cycle gas core nuclear rocket engines to further determine the optimum propulsive system for the C-City. Power and thermal control requirements were then defined and the question of how to meet these requirements was addressed. Software was developed to automate the mission/system/configuration analysis so changes dictated by various subsystems constraints could be managed efficiently and analyzed interactively. In addition, the liquid hydrogen propellant tank was statically designed for minimum mass and shape optimization using a finite element modeling package called SDRC I-DEAS while spoke and shaft cross-sectional areas were optimized on ASTROS (Automated Structural Optimization System). A structural dynamic analysis also conducted using ASTROS enabled a study of the displacements, accelerations, modes and frequencies of the C-City. Finally, the attitude control system design began with an initial mass moment of inertia analysis and was then designed and optimized using linear quadratic regulator control theory.

    2006-10-01

    We introduce the challenges of address geocoding for Chinese cities and present a potential solution along with a prototype system that deal with these challenges by combining and extending current geocoding solutions developed for United States and Japan. The proposed solution starts by separating city addresses into "standard" addresses which meet a predefined address model and non-standard ones. The standard addresses are stored in a structured relational database in their normalized forms, while a selected portion of the non-standard addresses are stored as aliases to the standard addresses. An in-memory address index is then constructed from the address database and serves as the basis for real-time address matching. Test results were obtained from two trials conducted in the city Beijing. On average 80% matching rate were achieved. Possible improvements to the current design are also discussed.

  8. City model enrichment

    Science.gov (United States)

    Smart, Philip D.; Quinn, Jonathan A.; Jones, Christopher B.

    The combination of mobile communication technology with location and orientation aware digital cameras has introduced increasing interest in the exploitation of 3D city models for applications such as augmented reality and automated image captioning. The effectiveness of such applications is, at present, severely limited by the often poor quality of semantic annotation of the 3D models. In this paper, we show how freely available sources of georeferenced Web 2.0 information can be used for automated enrichment of 3D city models. Point referenced names of prominent buildings and landmarks mined from Wikipedia articles and from the OpenStreetMaps digital map and Geonames gazetteer have been matched to the 2D ground plan geometry of a 3D city model. In order to address the ambiguities that arise in the associations between these sources and the city model, we present procedures to merge potentially related buildings and implement fuzzy matching between reference points and building polygons. An experimental evaluation demonstrates the effectiveness of the presented methods.

    Fifty years ago, the Atlantic City meetings, held the first week in May of every year, were attended by all the elite of American academic medicine and all who wanted to join that group. Part of the magic of those meetings was that professors and neophytes took each other seriously and talked to each other. PMID:18382726

  10. Classroom management at the university level: lessons from a former high school earth science teacher

    Science.gov (United States)

    Lazar, C.

    2009-12-01

    Just a few days before my career as a fledgling science teacher began in a large public high school in New York City, a mentor suggested I might get some ideas about how to run a classroom from a book called The First Days Of School by Harry Wong. Although the book seemed to concentrate more on elementary students, I found that many of the principles in the book worked well for high school students. Even as I have begun to teach at the university level, many of Wong’s themes have persisted in my teaching style. Wong’s central thesis is that for learning to occur, a teacher must create the proper environment. In education jargon, a good climate for learning is generated via classroom management, an array of methods used by elementary and secondary school teachers to provide structure and routine to a class period via a seamless flow of complementary activities. Many college professors would likely consider classroom management to be chiefly a set of rules to maintain discipline and order among an otherwise unruly herd of schoolchildren, and therefore not a useful concept for mature university students. However, classroom management is much deeper than mere rules for behavior; it is an approach to instructional design that considers the classroom experience holistically. A typical professorial management style is to lecture for an hour or so and ask students to demonstrate learning via examinations several times in a semester. In contrast, a good high school teacher will manage a class from bell-to-bell to create a natural order and flow to a given lesson. In this presentation, I will argue for an approach to college lesson design similar to the classroom management style commonly employed by high school and elementary school teachers. I will suggest some simple, practical techniques learned during my high school experience that work just as well in college: warm-up and practice problems, time management, group activities, bulletin boards, learning environment

  2. Less Smart More City

    Directory of Open Access Journals (Sweden)

    Rocco Papa

    2015-07-01

    Full Text Available Smart is an expression used in recent years in science, and it refers to someone or something that shows a lively intelligence, with a quick learning curve and a fast response to external stimuli. The present scenario is dominated by the accelerated technological development that involves every aspect of life, enhancing the everyday tools through the use of information and digital processing: everything is smart, even cities. But when you pair the term smart to a complex organism such as the city the significance of the two together is open to a variety of interpretations, as shown by the vast and varied landscape of definitions that have occurred in recent years. Our contribution presents the results of research aimed at analyzing and interpreting this fragmented scene mainly, but not exclusively, through lexical analysis, applied to a textual corpus of 156 definitions of smart city. In particular, the study identified the main groups of stakeholders that have taken part in the debate, and investigated the differences and convergences that can be detected: Academic, Institutional, and Business worlds. It is undeniable that the term smart has been a veritable media vehicle that, on the one hand brought to the center of the discussion the issue of the city, of increasing strategic importance for the major challenges that humanity is going to face,  and on the other has been a fertile ground on which to pour the interests of different groups and individuals. In a nutshell we can say that from the analysis the different approaches that each group has used and supported emerge clearly and another, alarming, consideration occurs: of the smart part of “Smart City” we clearly grasp the tools useful to the each group of stakeholders, and of the city part, as a collective aspiration, there is often little or nothing.

  13. Urbanization, housing, homelessness and climate change adaptation in Lagos, Nigeria: Lessons from Asia

    Directory of Open Access Journals (Sweden)

    Ilesanmi Adetokunbo

    2015-12-01

    Full Text Available The phenomenon of climate change heralds distinctive challenges for sub-Saharan Africa’s urban areas, with economic, social, and health impacts, and severe effects on housing and infrastructure. This study examined climate-change induced vulnerabilities including the urban housing crisis and homelessness in the context of Lagos mega-city, Nigeria, with a view to defining the potential lessons to learn from the Asian urban experience. The study conducted case-study analyses of Lagos and the Asian urban experience, highlighting the megacity-related vulnerabilities. It identified gender and aging as key factors in understanding vulnerability. Lessons from Asia relate to: the conscious policy-linkage of urban demographic expansion and economic growth; synergy between formal and informal sectors; urban densification through compact, mixed-land use development; broad-based urbanization; metropolitan expansion; pursuit of slum-free cities; prominence of housing in national policies; pro-poor financial frameworks; and extensive adoption of mitigation and adaptation strategies in the coastal conurbations. The paper concluded on the critical role of urban governance in reducing vulnerability, the need for greater multi-disciplinary stakeholders’ collaboration and partnership, and the expediency of fitting adaptation strategies and resilience responses to specific needs, capacities and priorities of impact groups. These could enhance the transformation of mega-cities into more adaptable and resilient urban systems.

  14. Assessing the Effects of the Urban Forest Restoration Effort of MillionTreesNYC on the Structure and Functioning of New York City Ecosystems

    2010-01-01

    Full Text Available Current forest restoration practices for New York City’s (NYC MillionTreesNYC Initiative on public parkland include site preparation with extensive invasive species removal and tree and shrub planting with the goal of creating new multi-layered forests. We have launched a long-term investigation of these sites in order to understand the primary physical, chemical, and biological responses of urban ecosystems to MillionTreesNYC forest restoration practices. This research will examine high and low diversity tree and understory planting combinations in permanent experimental forest restoration plots across NYC. The study assesses how the interactions between soil heterogeneity, plant population dynamics, and forest restoration management strategies drive urban forest ecosystem structure and functioning. Working in collaboration with the NYC Department of Parks & Recreation (NYC Parks and the MillionTreesNYC tree planting campaign, we are examining different restoration strategies to assess how restoration practices affect the ecological development trajectories of newly established forests in NYC.

    Southwest Airlines continues to garner accolades in the areas of customer service, workforce management, and profitability. Since both the health care and airlines industries deal with a service rather than a product, the customer experience depends on the people who deliver that experience. Employees' commitment or "loyalty" to their customers, their employer, and their work translates into millions of dollars of revenue. What employee wants to work for "the worst employer in town?" Nine loyalty lessons from Southwest can be carried over to the health care setting for the benefit of employees and patients. PMID:19330974

  20. Soft systems, hard lessons.

    Science.gov (United States)

    Kirwan, B

    2000-12-01

    This paper is concerned with practical experiences of achieving human factors and safety interventions in the nuclear power and process control industries. It rests upon the premise that, although human factors (HF) and safety may be technological in approach, they nevertheless must operate in a socio-technical environment, within companies with corporate structures and cultures, interacting with regulatory authorities. A crucial ingredient to the successful implementation and integration of human factors into company practices and procedures is therefore the nature of the inter-relationships between human factors personnel and those who control the existing procedures determining all aspects of the design and operational processes. Such inter-relationships can largely determine whether HF is implemented or not. These human-human interactions and interfaces in a socio-technical system may be referred to as soft systems. When training in human factors, much of the training is concerned with technical aspects of the discipline. However, when entering industry or consultancy, one quickly discovers that technical aspects are usually the least of one's problems. This paper is concerned with experiences and guidance to better help the human factors professional starting out in industry. There is little scientific method in the paper. It is, instead, a distillation of this author's and others' experiences in acting either as a practitioner or consultant, or as leader of a human factors unit in industries that have at times been reluctant or even hostile about the perceived 'invasion' of human factors. However, to avoid being purely anecdotal, the experiences are placed in a framework concerned with the life cycle of integrating human factors into an industry, from being the first HF person in a company, to the development of a successful unit, or the absorption of a successful unit into other departments. Within this framework a range of strategic aspects are dealt with
