Full Text Available The topic of this issue is PUBLIC SPACES. It is familiar and clear to every citizen. The streets and courtyards as childhood experiences remain with us forever. And these are the places where we come with our parents at weekends, where we meet friends, where we have dates and where we already come for a walk with our children.The history of public spaces is long and captivating. It was the main city squares where the most important events took place in history. The Agoras of Ancient Greece and the Roman Forums, the squares of Vatican, Paris and London, Moscow and Saint Petersburg… Greve, Trafalgar, Senate, Palace, Red, Bolotnaya – behind every name there is life of capitals, countries and nations.Public spaces, their shapes, image and development greatly influence the perception of the city as a whole. Both visitors and inhabitants can see in public spaces not only the visage but the heart, the soul and the mind of the city.Unfortunately, sometimes we have to prove the value of public spaces and defend them from those who consider them nothing but a blank space, nobody’s land destined for barbarous development.What should happen to make citizens perceive public spaces as their own and to make authorities consider development and maintenance of squares and parks their priority task against the  background of increasing competition between cities and the fight for human capital? Lately they more often say about “a high-quality human capital”. And now, when they say “the city should be liveable” they add “for all groups of citizens, including the creative class”.

Hankel transforms in generalized Fock spaces

Directory of Open Access Journals (Sweden)

John Schmeelk

1994-01-01

Full Text Available A classical Fock space consists of functions of the form,ϕ↔(ϕ0,ϕ1,…,ϕq,where ϕ0∈ℂ and ϕq∈Lp(ℝq, q≥1. We will replace the ϕq, q≥1 with test functions having Hankel transforms. This space is a natural generalization of a classical Fock space as seen by expanding functionals having abstract Taylor Series. The particular coefficients of such series are multilinear functionals having distributions as their domain. Convergence requirements set forth are somewhat in the spirit of ultra differentiable functions and ultra distribution theory. The Hankel transform oftentimes implemented in Cauchy problems will be introduced into this setting. A theorem will be proven relating the convergence of the transform to the inductive limit parameter, s, which sweeps out a scale of generalized Fock spaces.

Radon transformation on reductive symmetric spaces: support theorems

NARCIS (Netherlands)

Kuit, J.J.|info:eu-repo/dai/nl/313872589

2011-01-01

In this thesis we introduce a class of Radon transforms for reductive symmetric spaces, including the horospherical transforms, and study some of their properties. In particular we obtain a generalization of Helgason's support theorem for the horospherical transform on a Riemannian symmetric space.

Sequential Generalized Transforms on Function Space

Jae Gil Choi

2013-01-01

Full Text Available We define two sequential transforms on a function space Ca,b[0,T] induced by generalized Brownian motion process. We then establish the existence of the sequential transforms for functionals in a Banach algebra of functionals on Ca,b[0,T]. We also establish that any one of these transforms acts like an inverse transform of the other transform. Finally, we give some remarks about certain relations between our sequential transforms and other well-known transforms on Ca,b[0,T].

The case for transforming governmental public health.

Science.gov (United States)

Salinsky, Eileen; Gursky, Elin A

2006-01-01

Changing threats to the public's health necessitate a profound transformation of the public health enterprise. Despite recent attention to the biodefense role of public health, policymakers have not developed a clear, realistic vision for the structure and functionality of the governmental public health system. Lack of leadership and organizational disconnects across levels of government have prevented strategic alignment of resources and undermined momentum for meaningful change. A transformed public health system is needed to address the demands of emergency preparedness and health protection. Such transformation should include focused, risk-based resource allocation; regional planning; technological upgrades; workforce restructuring; improved integration of private-sector assets; and better performance monitoring.

Theorizing Critical Placemaking as a Tool for Reclaiming Public Space.

Science.gov (United States)

Toolis, Erin E

2017-03-01

As economic inequality and segregation continue to grow in the U.S., psychology has an important role to play in exploring and promoting processes that can disrupt social injustice. This paper identifies the privatization of public space as a social problem that contributes to the entrenchment of social, economic, and racial inequality, and advances "critical placemaking" as a tool for reclaiming public space for public use. Drawing from key concepts in environmental psychology, narrative psychology, and community psychology, the proposed framework seeks to theorize the processes by which placemaking may contribute to transforming community narratives and building more inclusive, participatory, and democratic communities. Policy implications and future directions for empirical work are discussed. © Society for Community Research and Action 2017.

Frame transforms, star products and quantum mechanics on phase space

International Nuclear Information System (INIS)

Aniello, P; Marmo, G; Man'ko, V I

2008-01-01

Using the notions of frame transform and of square integrable projective representation of a locally compact group G, we introduce a class of isometries (tight frame transforms) from the space of Hilbert-Schmidt operators in the carrier Hilbert space of the representation into the space of square integrable functions on the direct product group G x G. These transforms have remarkable properties. In particular, their ranges are reproducing kernel Hilbert spaces endowed with a suitable 'star product' which mimics, at the level of functions, the original product of operators. A 'phase space formulation' of quantum mechanics relying on the frame transforms introduced in the present paper, and the link of these maps with both the Wigner transform and the wavelet transform are discussed

Quaternionic formulation of tachyons, superluminal transformations and a complex space-time

Energy Technology Data Exchange (ETDEWEB)

Imaeda, K [Dublin Inst. for Advanced Studies (Ireland)

1979-04-11

A theory of tachyons and superluminal transformations is developed on the basis of the quaternionic formulation. A complex space-time adn a complex transformation group which contains both Lorentz transformations and superluminal transformations are introduced. The complex space-time '' the biquaternion space'' which is closed under the superluminal transformations is introduced. The principle of special relativity, such as the conservation of the quadratic form of the metric of the space-time, and the principle of duality are extended to the complex space-time and to bradyons, luxons and tachyons under the complex transformations. SeVeral characteristic features of the superluminal transformations and of tachyons are derived.

SUSTAINABILITY OF DIGITAL PUBLIC SPACES

Directory of Open Access Journals (Sweden)

Matej Hudák

2015-07-01

Full Text Available Purpose: Modern digital public spaces are evolving from being mostly the provider of ICT and internet connection to institutions that provide complex range of services and support for the community. With this shift in their focus new challenges are emerging, among others their sustainability.Methodology/Approach: We build on and extend the methodology of Digital Cooperatives project. Within this project, survey on 59 digital public spaces from 12 EU countries was conducted. These digital public spaces were examined in 21 areas, some of them relating to their sustainability. We further analyse the sustainability issue of these digital public spaces.Findings: We identified three main issues affecting sustainability of digital public spaces – budgeting, services and community. Digital public spaces mostly rely on public funding and have limited diversification of their funds, which increases a risk when one source of funding drops out. They also have to build a strong community of users, supporters, which will make use of their capacities and helps co-create new services and thus strengthen and improve the community itself.Originality/Value of paper: Research in this paper is based on the collection of best practices from various EU countries in the field of digital public spaces. Recommendations based on these practices could help the creation of new, and in current digital public spaces.

Publicity and identity in the public space architecture

Maria de Lourdes Carneiro da Cunha Nóbrega

2009-12-01

Full Text Available This article aims at showing the relationship between publicity elements, such as posters and signs, with the city architecture, so that the contribution of these elements with the identity of the urban sites, especially the historical ones, can be understood. In order to do that, a focal point is given to Rua da Palma, located in the city of Recife (Pernambuco, Brazil. For the development of this research, which was based on the present morphological analysis of the site, a survey of photographs and the use of the buildings in the street from 2006 to 2009 was carried out. Also, the existing urban legislation was analyzed. Studies undertaken by authors such as Certau (1994, Venturi (1977 and Koolhaas (2004, among others, and concepts related to retail marketing helped in the conclusion of this analysis of the urban space, which presents architecture as a publicity media, often transforming the identity of the area. A starting point is presented here for future investigation on the role of urban laws and urban control, which deal with the placement of publicity elements in the architecture of the city and contribute for the formation or the urban landscape. This landscape which is considered an integral part of a cultural identity.

Transforming communicative spaces: the rhythm of gender in meetings in rural Solomon Islands

Directory of Open Access Journals (Sweden)

Michelle Dyer

2018-03-01

Full Text Available Women's lack of participation in important decision making is noted as an obstacle to sustainable development in many parts of the world. An initial issue for gender equity in environmental decision making in many developing country contexts is not only women's inclusion but also their substantive participation in decision-making forums. In this article I examine the power structures embedded in the public communicative spaces in a village in the Western Province of Solomon Islands using empirical data in conjunction with ethnographic understanding of gendered meeting styles. The data reveal some reasons why women may be silenced as public political actors. It also raises the potential for development actors to create conceptual space for specific women's ways of meeting and validating women's meeting styles. These findings have implications for encouraging transformative communicative spaces and formats that allow transcendence of socially embedded power structures.

China’s post-reform modernisation and hyper-urbanisation have brought new public spaces to Chinese cities. This article examines the development of a public sphere and five types of new public spaces: newly-open landscapes, squares, commercial spaces, “green” spaces, and transitional spaces. Specific examples are drawn from Beijing, Shanghai, and Xining.

Organising a Safe Space for Navigating Social-Ecological Transformations to Sustainability

Directory of Open Access Journals (Sweden)

Laura Pereira

2015-05-01

Full Text Available The need for developing socially just living conditions for the world’s growing population whilst keeping human societies within a ‘safe operating space’ has become a modern imperative. This requires transformative changes in the dominant social norms, behaviours, governance and management regimes that guide human responses in areas such as urban ecology, public health, resource security (e.g., food, water, energy access, economic development and biodiversity conservation. However, such systemic transformations necessitate experimentation in public arenas of exchange and a deepening of processes that can widen multi-stakeholder learning. We argue that there is an emergent potential in bridging the sustainability transitions and resilience approaches to create new scientific capacity that can support large-scale social-ecological transformations (SETs to sustainability globally, not just in the West. In this article, we elucidate a set of guiding principles for the design of a ‘safe space’ to encourage stronger interactions between these research areas and others that are relevant to the challenges faced. We envisage new opportunities for transdisciplinary collaboration that will develop an adaptive and evolving community of practice. In particular, we emphasise the great opportunity for engaging with the role of emerging economies in facilitating safe space experimentation.

The public space of social media connected cultures of the network society

CERN Document Server

Tierney, Therese

2013-01-01

Social media is restructuring urban practices-through ad-hoc experimentation, commercial software development, and communities of participation. This book is the first to consider how practices contained within social media are situated within a larger genealogy of public space, including theories of communal identity, civitas and democracy, the fete, and self-expression. Through empirical research, the actual social practices of participants of networked publics are described and analyzed. Documenting how online counterpublics use the Internet to transmit classified photos, mobilize activists, and challenge the status quo, Tierney argues that online activities do not stop in online conversations; they are physically grounded through mobile GPS coordinates which are then transformed into activities in physical space-the street, the plaza, the places where people have traditionally gathered to demonstrate and express their opinions publicly.

Public choice economics and space policy: realising space tourism

Science.gov (United States)

Collins, Patrick

2001-03-01

Government space agencies have the statutory responsibility to suport the commercialisation of space activities. NASA's 1998 report "General Public Space Travel and Tourism" concluded that passenger space travel can start using already existing technology, and is likely to grow into the largest commercial activity in space: it is therefore greatly in taxpayers' economic interest that passenger space travel and accommodation industries should be developed. However, space agencies are doing nothing to help realise this — indeed, they are actively delaying it. This behaviour is predicted by 'public choice' economics, pioneered by Professors George Stigler and James Buchanan who received the 1982 and 1986 Nobel prizes for Economics, which views government organisations as primarily self-interested. The paper uses this viewpoint to discuss public and private roles in the coming development of a space tourism industry.

Public Spaces - Coexistence and Participation

Stasiak, Anna; Wojtowicz-Jankowska, Dorota

2017-10-01

The paper is an attempt to answer two questions: (1) how to develop positive social relations and citizenship among residents of cities in Poland and (2) how suitable shaping of public space affects the activation and integration of local residents. The specificity of the postwar process of urbanization in Poland - a country traditionally agricultural - was its political dimension (forced “nationalisation” of agriculture and industrialization of the country) ignoring the socio-cultural determinants and consequences of this process resulting in disappearance of traditional social bonds. According to forecasts, the number of urban dwellers is expected to grow by the year 2050 and increase up to 70 percent of the population. Such a rapid urban sprawl was not accompanied by appropriate social policies; the result was a low level of social organization and of a sense of citizenship. There are various attempts to change this situation. One of them is the development of a system of urban public spaces, according to the needs and preferences of residents (i.e. promotion of physical activity in public areas, introducing elements of art to the common external space, encouraging users to contribute to their surroundings and introducing the appearance of temporary, often cyclical, attractions). Regular interactions between people in public spaces are conducive to developing positive social relationships. Quality and development of the local community is dependent on the quality of space in which it is built. For this reason, attention has been paid to the factors influencing the perception of public space, i.e. geographical and natural conditions, cultural and architectural (arrangement, the availability and condition of these spaces). In the article, the examples of different types of Polish public spaces are described - permanent and temporal recreational spaces (including summer activities and winter attractions). Attempt has also been made to give an answer to the

Spatial Character Analysis of Streets as Public Spaces: The Case of Izmit Hurriyet and Cumhuriyet Street, Turkey

The word “public” was first used to refer to the theatre audience in France in the mid-17th century. In the 18th century, it turned into the meaning of “public space incorporating a large variety of people and composed of acquaintances and strangers”. The concepts of publicity, public space, and public realm have been studied and described by many researchers in the course of time. These descriptions show the development of public space as well. In the very general sense, public spaces are areas of personal and social happiness; collective living spaces of the society; areas of expression of natural and cultural variety; and key elements providing a ground for the establishment of an identity. In the United Nations’ report on public spaces, public space is addressed under six groups: 1. The spaces we intensely used in our daily life; 2. Green open public spaces; 3. Public activity spaces which users can go in without any difficulty, are open to public, and are under protection; 4. Public sector realm (social agreements in which the people are represented, contribute to collective goods, and trust in the administrators elected); 5. City as a public space; 6. Cyberspace. As cities grow, public spaces transform and diversify. Attempts are made to meet the changing needs through types of space developed. However, the character of the existing public spaces, the distribution of open spaces and parks and their inadequacy, the destruction of public space, and the things that are required to be done stand as important issues to be addressed. One of the public spaces going through transformation are streets which we intensely use in our daily life. In general, streets are defined as roads with buildings on both sides in settlements such as provinces and districts whose boundaries are determined by neighbouring buildings. Some researchers have defined streets based on their social functions. According to them, streets are meeting spaces; spaces to deal with

Gender and Space: Analysis of Factors Conditioning Equity in the Public Space

Directory of Open Access Journals (Sweden)

Pablo Paramo Bernal

2011-01-01

Full Text Available This article discusses gender research in urban public space through three different perspectives: the social representations and differentiated uses of space, the division of roles in public and private spaces, and urban planning of public space. The paper gathers and analyses some studies that complement the state of art and literature on women and space giving evidence on how women have been segregated from public space and are victim of gender inequalities. Public space does not exist absolutely nor gender; instead both are socially constructed by social order and reproduced by social practices. Finally, some suggestions for urban planning and research are given in order to respond women’s needs in public space.

The belives on the asphalt. Sacred sites as means of appropriation of the public space in México City

Directory of Open Access Journals (Sweden)

María Ana Portal

2009-07-01

Full Text Available This paper explores how residents of México City appropriate public spaces by transforming local places into sacred sites.  This sacred quality is achieved by installing crucifixes, altars and niches for virgins and saints.  These symbols of folk religion not only adorn public sites, but also offer protection, serve as mnemonic devices and manage spatial liminality -all this in a chaotic city where public spaces are considered to be almost extinct.  These elements -- faces, proper names, common religious symbols- mark “anonymous” urban spaces, generating meaning and memory for inhabitants.  In this fashion, public spaces become a scenario for projecting personal elements of  neighborhood groups.

Providing Public Space Continuities in Post-Industrial Areas through Remodelling Land/Water Connections

Science.gov (United States)

Burda, Izabela M.; Nyka, Lucyna

2017-10-01

This article examines the problem of urban transformation strategies applied in recent years which are based on the creation of new water areas and modification of existing ones. The research is an attempt to prove that modifications of plans of water areas and forms of their borders may play an important role in achieving the best quality public spaces in post-industrial territories. The basis for demonstrating the importance of modifying water borders, and introducing new forms of water-based structures in cities, are theoretical surveys, comparative studies and in-field analyses. It can be seen that post-industrial areas, which used to create voids in the urban fabric, can be perceived as unique but isolated places that should be integrated into the layout of cities. Thus, creating continuity of public spaces that will relate converted areas to their surroundings is a well-known objective of many transformation strategies. This research proves that an effective strategy toward achieving this goal can be based on the modification of relationships between land and water. Namely, the introduction of new water areas, designing new pieces of land that protrude into the water, softening the boundaries of water lines or the opposite, like structuring smaller water flows into well-defined canals, may significantly contribute to the quality of public spaces. As such, all of this fosters the development of sustainable cities and contributes significantly to the emergence of high-quality urban landscapes.

Kuala Lumpur has envisioning in becoming World Class City by the year 2020. Essential elements of form and function of the urban environment are streets. Streets showcase the community and connect people. It’s one of the most comfortable social environment that provides aesthetical and interaction pleasure for everyone. Classified as main shopping streets in the local Kuala Lumpur urban design guidelines, Jalan Masjid India (JMI) has its uniqueness of shopping experience and social interaction. This conceptual paper will study the physical and cultural characteristics of the street that will generate the street character by mapping its original characters. The findings will focus on strengthening the methodology applied to promote improvements in evaluating it as a great public space. Results will also contribute to understanding the overall site context, the street connectivity, and urban dynamics. This paper is part of a larger study that addresses on transforming the sociability of public space.

Public relations educators are frequently challenged by students' flawed perceptions of public relations. Two contrasting case studies are presented in this paper to illustrate how socially-oriented paradigms may be applied to a real-client project to deliver a transformative learning experience. A discourse-analytic approach is applied within the…

Outlier Detection with Space Transformation and Spectral Analysis

which rely on notions of distances or densities, this approach introduces a novel concept based on local quadratic entropy for evaluating the similarity of a data object with its neighbors. This information theoretic quantity is used to regularize the closeness amongst data instances and subsequently......Detecting a small number of outliers from a set of data observations is always challenging. In this paper, we present an approach that exploits space transformation and uses spectral analysis in the newly transformed space for outlier detection. Unlike most existing techniques in the literature...... benefits the process of mapping data into a usually lower dimensional space. Outliers are then identified by spectral analysis of the eigenspace spanned by the set of leading eigenvectors derived from the mapping procedure. The proposed technique is purely data-driven and imposes no assumptions regarding...

Pedro Brandão

2015-06-01

• In the development of design practice and studio teaching methods We shall see in this paper how interdisciplinary approaches correspond to new and complex urban transformations, focusing on the importance of actors’ interaction processes, combining professional and non-professional knowledge and theory-practice relations. Therefore, we aim at a deepening in public space area of knowledge under the growing complexity of urban life. We see it as a base for further development of collaborative projects and their implications on community empowerment and urban governance at local level. Motivations of this line of work are persistent in several ongoing research projects, aiming to: - Understand public space as a cohesion factor both in urban life and urban form - Manage processes and strategies as elements of urban transformation, - Stimulate the understanding of actors’ roles in urban design practices. - Favoring the questioning of emerging aspects of urban space production… The paper presents and analyses processes, methods and results from civic participation projects developed in the neighbourhood of Barò de Viver (Barcelona and in the District of Marvila (Lisbon. In the first case, a long process initiated in 2004 and partially completed in 2011, neighbours developed the projects "Memory Wall" and Ciutat d'Asuncion Promenade as part of identity construction in public space, in collaboration  with a team of facilitators from CrPolis group. In the second case, different participatory processes dated from 2001 and 2003 have resulted in the implementation of a specific identity urban brand and communication system with an ongoing project of "maps" construction according to the neighbours perception and representation systems. We may conclude that processes of urban governance require more active participation of citizens in projects regarding the improvement of quality of life. At the same time, the implementation of these processes requires a clear

Discrete Fourier Transform in a Complex Vector Space

Science.gov (United States)

Dean, Bruce H. (Inventor)

2015-01-01

An image-based phase retrieval technique has been developed that can be used on board a space based iterative transformation system. Image-based wavefront sensing is computationally demanding due to the floating-point nature of the process. The discrete Fourier transform (DFT) calculation is presented in "diagonal" form. By diagonal we mean that a transformation of basis is introduced by an application of the similarity transform of linear algebra. The current method exploits the diagonal structure of the DFT in a special way, particularly when parts of the calculation do not have to be repeated at each iteration to converge to an acceptable solution in order to focus an image.

Index hypergeometric transform and imitation of analysis of Berezin kernels on hyperbolic spaces

International Nuclear Information System (INIS)

Neretin, Yu A

2001-01-01

The index hypergeometric transform (also called the Olevskii transform or the Jacobi transform) generalizes the spherical transform in L 2 on rank 1 symmetric spaces (that is, real, complex, and quaternionic Lobachevskii spaces). The aim of this paper is to obtain properties of the index hypergeometric transform imitating the analysis of Berezin kernels on rank 1 symmetric spaces. The problem of the explicit construction of a unitary operator identifying L 2 and a Berezin space is also discussed. This problem reduces to an integral expression (the Λ-function), which apparently cannot be expressed in a finite form in terms of standard special functions. (Only for certain special values of the parameter can this expression be reduced to the so-called Volterra type special functions.) Properties of this expression are investigated. For some series of symmetric spaces of large rank the above operator of unitary equivalence can be expressed in terms of the determinant of a matrix of Λ-functions

PREPARING THE PUBLIC FOR COMMERCIALIZATION AND GUIDANCE OF STRUCTURAL MEDIA SPACE TOWARDS ITS FUSION WITH ADVERTISING SPACE

Full Text Available Through genre structure analysis of the Television´s Zagreb First Channel schedule from the beginning of 1970´s till the end of the 1980´s accompanied by analysis of advertising in same period, the paper will examine the ways and intensity of commercialization entrance in Croatian media space dominated then by state media. Television schedule genre change and the broadcast of economic propaganda program will point out the different character of the television. It can be said that it will serve for preparing the public for commercialization entrance and guidance of structural media space towards its fusion with advertising one. The assumption is that in spite of the TV schedule change, which was in economic sense accompanied by economy reforms in order to establish market economy, the public wasn´t yet delivered to advertisers. One of the clarification lies in the role of the media, which then had revolutionary function with main purpose of not the voters’ generation but only to create patriots. The paper will reproduce a kind of public transformation genesis from latent status in state guided media system to same status of latent consumers in dual media model.

Public Space and Plurality of Beliefs

Directory of Open Access Journals (Sweden)

Francesc Rovira i Llopart

2007-06-01

Full Text Available In this work, the author deals with how the issue of religion can be managed in the public space. For this, he wonders and argues whether or not the public space should be a homogeneous space from the point of view of convictions or if it can give room to heterogeneousexpressions, stemming from the plurality of profound convictions existing among the citizens. In addition, he lays out the concept of public space, discusses its “contaminations” and focuses fundamentally on its meaning as a place in which the supply, exchangeand debate of ideas, principles, intuitions, etc. are openly developed, although he devotes a little bit of attention to their most tangible or physical aspects. And he underscores the idea that in a context of democratically chosen public powers and a secular institutional framework, there should not exist privileges nor discriminations.

Transformation of Space in the Adaptation of La straniera

Mahmoud Jaran

2012-11-01

Full Text Available The article aims to examine the transformations of space in the adaptation of La straniera, the novel of the Iraqi writer Younis Tawfik, made by the Italian director Marco Turco. The importance of these two works, which have recently won the Med Agora Award, sponsored by the Mediterranean Observatory and Suq Festival, comes from an historical value, since the film La straniera is one of the first film adaptations of Italian Narrative of Migration. From a textual analysis that highlights the differences between the themes in the novel and the screenplay, the article passes to the transformations of space, with the purpose of illustrating a series of reports linking the spatial coordinates with their geo-cultural values. The textual analysis leads also to consider the gap between the intercultural project of Tawfik and multicultural one of Turco. In conclusion, the article demonstrates, through an “the image of Italy” provided by the Iraqi author and the Italian director, how the spatial transformation may give rise to new interpretations of space, impacting on the original message of the literary text.

Forecasts of non-Gaussian parameter spaces using Box-Cox transformations

Science.gov (United States)

Joachimi, B.; Taylor, A. N.

2011-09-01

Forecasts of statistical constraints on model parameters using the Fisher matrix abound in many fields of astrophysics. The Fisher matrix formalism involves the assumption of Gaussianity in parameter space and hence fails to predict complex features of posterior probability distributions. Combining the standard Fisher matrix with Box-Cox transformations, we propose a novel method that accurately predicts arbitrary posterior shapes. The Box-Cox transformations are applied to parameter space to render it approximately multivariate Gaussian, performing the Fisher matrix calculation on the transformed parameters. We demonstrate that, after the Box-Cox parameters have been determined from an initial likelihood evaluation, the method correctly predicts changes in the posterior when varying various parameters of the experimental setup and the data analysis, with marginally higher computational cost than a standard Fisher matrix calculation. We apply the Box-Cox-Fisher formalism to forecast cosmological parameter constraints by future weak gravitational lensing surveys. The characteristic non-linear degeneracy between matter density parameter and normalization of matter density fluctuations is reproduced for several cases, and the capabilities of breaking this degeneracy by weak-lensing three-point statistics is investigated. Possible applications of Box-Cox transformations of posterior distributions are discussed, including the prospects for performing statistical data analysis steps in the transformed Gaussianized parameter space.

Stüßer, N., E-mail: stuesser@helmholtz-berlin.de; Bartkowiak, M.; Hofmann, T.

2014-06-01

We extend geometries for recently developed optical guide systems that perform homogeneous phase space volume transformations on neutron beams. These modules allow rotating beam directions and can simultaneously compress or expand the beam cross-section. Guide systems combining these modules offer the possibility to optimize ballistic guides with and without direct view on the source and beam splitters. All systems are designed for monochromatic beams with a given divergence. The case of multispectral beams with wavelength-dependent divergence distributions is addressed as well. - Highlights: • Form invariant volume transformation in phase space. • Geometrical approach. • Ballistic guide, beam splitter, beam bender.

Patriotic Rhetoric in Chinese Public Spaces

Directory of Open Access Journals (Sweden)

Pawel Zygadlo

2017-10-01

Full Text Available This paper begins with the analysis of the socio-cultural phenomenon known as “public space.” This analysis is followed by the reflection on distinctive features of public space in contemporary China. Subsequently, I focus on the use of public space by Chinese authorities for spreading official political and ideological discourse. For this purpose, I analyse the form and content of messages displayed in places of public utility. I conclude by showing what, how and why these are being displayed and widely promoted by the authorities. I argue that public space in China, on the one hand, is “public” in the sense that it is accessible and used by citizens; on the other, it is “arrested by authorities” and used for their socio-political and ideological purposes. Such an arrangement is a statement of the unvocalised agreement between the authorities and citizens that allows the former to avoid major conflicts with the latter and legitimise political power. In return, the latter enjoy a wide range of socio-cultural freedom and are being provided with psychological comfort resulting from identification with a greater endeavour of restoring the glory of the Chinese nation.

From the habermasian space to the new forms of the public space

Directory of Open Access Journals (Sweden)

Dinu (Stan, E.-L.

2011-01-01

Full Text Available The Habermasian theoretical perspective offers, in the literature, a detailed image of the “public sphere” concept signification. Being applied, over the years, in issues related to media theories too (globalisation, consumerism, democracy, the concept of “public sphere” has undergone radical changes due, mainly, to the emergence and convergence of electronic media. In this respect, this article does nothing more than to describe and analyze, in a realistic way, the public space, the mechanisms involved in it, as well the interplay of the public space with the private one. We could say that this dissolution of the public space is one of the major consequences of postmodernism.

Transformational Technologies to Expedite Space Access and Development

International Nuclear Information System (INIS)

Rather, John D. G.

2010-01-01

Throughout history the emergence of new technologies has enabled unforeseen breakthrough capabilities that rapidly transformed the world. Some global examples from the twentieth century include AC electric power, nuclear energy, and turbojet engines. At the systems level, success of both Apollo and the Space Shuttle programs depended upon taming hydrogen propulsion and developing high-temperature atmospheric reentry materials. Human space development now is stymied because of a great need for breakthrough technologies and strategies. It is believed that new capabilities exist within the present states-of-the-art of superconducting technology that can be implemented to transform the future of human space development. This paper is an overview of three other papers presented within this forum, which summarizes the principles and consequences of StarTram, showing how the resulting breakthrough advantages can lead directly to safe space tourism and massive development of the moon, Mars and the outer solar system. StarTram can implement cost-effective solar power from space, simple utilization of asteroid material to protect humans from ionizing radiation, and effective defense of the Earth from devastating cosmic impacts. Synergistically, StarTram technologies will revolutionize ground transportation on the Earth, leading to enormous reduction in energy consumption and creation of millions of jobs. High energy lasers will also be discussed because of their importance to power beaming applications.

Bacová, Andrea; Puškár, Branislav; Vráblová, Edita

2017-10-01

The housing estates in Bratislava saturated the housing needs of a large number of inhabitants who come after World War II to the city. Design of public spaces often did not have priority in the process of designing. The solutions for mentioned exterior spaces had been planned after blocks of flat realization, but many of them are not realized to this day. The article analyzes the example of the unrealized public spaces in existing housing estates Devinska Nova Ves and Petržalka (city districts of Bratislava) and offer practical solutions in relation to residencialization method. Residencialization of missing public places is an effective method of adding identities to settlements. It improves the quality of residential environment and public spaces. The main aim is to create better conditions for social activities in public areas, which are missing on the present. The research will be focused on the examination of the urban, cultural and construction potential of the existing residential enviroment in Bratislava. The main aim of residentialization is not only to enhance the quality of spatial and building structures in the selected residential area and maintain long-term sustainability in the pertinent programme area, but mainly to improve the quality of living for the residents. The outputs of the project are proposals and practical procedures developed with regard to planning documents for local municipal authorities and regional organizations. The solutions will have a positive impact on the enhancement of the quality of public spaces, attractive social activities and of a conceptual link - residentialization.

A Study about Youth and Uses of Public Spaces

Directory of Open Access Journals (Sweden)

Fardin Alikhah

2016-04-01

Full Text Available There has been a huge concern about the manner of confrontations of different social groups with urban public spaces within urban scholars. Among these social groups, young people have been particularly important. Because they have a tangible presence in the city's public spaces and social life of the city are affected by their presence. This paper examines the uses of public spaces by young people and will pay special attention to the role of social control on use of public spaces. Paper focuses on the study of young people who attend in public places with their friends from opposite sex. We have inspired by theories of urban public spaces such as Oldenburg's third place as well as comprehensive research of Rob White on crime, policing and urban public spaces in Australia in this paper. The main question of the paper is that this particular group of young people choose which public spaces and why? In a qualitative approach, two techniques of observation and in - depth interviews have been chosen for collecting data. Original data collected in interviews with 20 girls and boys who attend in public places with their friends from opposite sex. Results show that parks and coffee shops are preferred urban public places of youth. Formal control would push these youth to out of the way and cozy public spaces.

Space-Time Transformation in Flux-form Semi-Lagrangian Schemes

Full Text Available With a finite volume approach, a flux-form semi-Lagrangian (TFSL scheme with space-time transformation was developed to provide stable and accurate algorithm in solving the advection-diffusion equation. Different from the existing flux-form semi-Lagrangian schemes, the temporal integration of the flux from the present to the next time step is transformed into a spatial integration of the flux at the side of a grid cell (space for the present time step using the characteristic-line concept. The TFSL scheme not only keeps the good features of the semi-Lagrangian schemes (no Courant number limitation, but also has higher accuracy (of a second order in both time and space. The capability of the TFSL scheme is demonstrated by the simulation of the equatorial Rossby-soliton propagation. Computational stability and high accuracy makes this scheme useful in ocean modeling, computational fluid dynamics, and numerical weather prediction.

Exploring Association between Morphology of Tree Planting and User Activities in Urban Public Space; An opportunity of Urban Public Space Revitalisation

Shen, Qi; Liu, Yan

2018-03-01

This paper discusses the association between the morphology of tree planting in urban riverside brown field and user activities. With the growth of popularity, the revitalisation of urban public space is also promising. This research used drone photography and mapping to systematically surveys sample sites. An original observation study of user activities proceed in four sample public spaces in Sheffield. The study results found there are huge popularity and duration difference of user activities between various tree planting morphologies and typologies. The public space with lawn and rounded by mature trees attracted most users with the most activity types; the neat and silent public space is the favourite choice of lunch and reading, meanwhile it got the longest activity duration; but the space with sparse morphology and small trees are more likely be forgotten and abandoned. This finding offered a great opportunity for urban public space revitalisation in post-industrial cities.

The impact of crime and the fear thereof on the nature and use of public space in the capital city of South Africa

Directory of Open Access Journals (Sweden)

Karina Landman

2017-08-01

Full Text Available Levels of insecurity, crime and inequality remain very high in Brazilian and South African cities. Consequently, wealthier residents retreat to protected common spaces behind walls and fences. As a result, there has been a growth of many quasi-public spaces in shopping malls and gated communities. This raises questions regarding the change of public space and the impact of crime and the fear thereof on the use of these spaces. The discussion shows how the form and function of different spaces in the capital city of South Africa, Pretoria, have changed in various parts of the city through neglect, revitalization and privatization and how this have shaped the experience of users in relation to crime and the fear thereof. The paper argues for a more nuanced reading of the transformation of public space. Firstly, it recognizes that in rapidly changing cities of transitional countries there may still be a need for different types of public spaces, including those in gated communities. Secondly, although safety is a major concern among users of public space, it does not imply that gated communities offers the only solution to safe public space. Therefore, alternatives approaches should be considered.

Space Livability of Street Vendors in Simpang Lima Public Space, Semarang

Widjajanti, R.; Wahyono, H.

2018-02-01

Street vendors in Semarang have been growing rapidly and uncontrolled. They always use public space such as public roads, sidewalks, parks and fields as trading locations. The street vendors’ activities in the public space are considered as the cause of declining on environmental quality and aesthetics of the city. All these years, the government often evicted the street vendors than organized and provides adequate space for them. As one of the actual urban activities, the street vendors’ activities should be accommodated by the government and the location for them is managed in the urban spatial plan. Street vendors need spaces which livable and suitable to their activities’ requirements, has a relationship with users (street vendors’ doers and consumers) and the activities of street vendors themselves. Research on the aspect of space for street vendors is still less in quantity, whereas space for them is an urgent matter for the government in managing their activities. This study aims to identify the livability of space based on the street vendors’ behavior in their location. This research used descriptive quantitative method with questionnaires and GIS as the mapping tool for street vendors’ location. The result of the research shows that the livability of street vendor space is based on the activity of street vendors (type of merchandise, trading places’ size, trade place assessment, space dimension, trading time, duration and period) and space conditions (access, natural elements, safety and parking space).

Ideas, words, images and stories travel from west to east – and from east to west. Stories are chosen and retold in different settings and images are reproduced and appropriated into new contexts – and in new times. Cinema, in this case the mainland Chinese, becomes both a space of production...... and a production of space that reveals how transnational and translocal mechanisms affect the cinematic language, transforming the images and stories chosen for the cinematic representation. Wang Xiaoshuai’s Beijing Bicycle (Shiqi Sui de Danche) (2001) is a result of transnational currents weaving the carpet...... relevant in a new context – that of the Chinese mainland society in the 21st century.

Jun, Soo Young

2017-12-01

This study was to verify the effect of public health nurse's (PHN's) social capital on the relationship between public health manager's (PHM's) transformational leadership and PHN's organizational empowerment in Korea public health. This was a cross-sectional descriptive study involving 303 PHNs from public health centers in Daegu and Gyeongsangbuk-do cities in South Korea. Data were collected from February 29, 2016 to April 8, 2016, using structured questionnaires which included general characteristics, transformational leadership, organizational empowerment, and social capital. Data were analyzed using descriptive statistics, correlations, and structural equation model. PHM's transformational leadership has a positive effect on PHN's social capital and PHN's organizational empowerment. Social capital had a mediating effect between transformational leadership and organizational empowerment in PHNs. This study suggests that PHM's transformational leadership is a contributing factor to improve PHN's organizational empowerment, and transformational leadership can lead to improve PHN's organizational empowerment through PHN's social capital. So, an intervention program to promote organizational empowerment should include strategies to enhance PHM's transformational leadership as well as to improve PHN's social capital. Copyright © 2017.

What is the public's role in 'space' policymaking? Images of the public by practitioners of 'space' communication in the United Kingdom.

Science.gov (United States)

Entradas, Marta

2016-07-01

Studies on experts' understanding of the public have mainly focused on the views of scientists. We add to the literature on constructions of the public by analyzing the views of decision-makers, professional science communicators and scientists involved in 'space' communication on the public and public participation in policy. Findings show that contextual situations and roles determine the way the public is conceptualised: the public is sophisticated and knowledgeable to participate in space activities/citizen science, but in matters of policy, a gullible image of the public is brought up. Despite the democratic talk on participation, practitioners delimited public involvement in policy in some way or other to protect their own power and decision-making capabilities. This conception of the public competes with the stated aims of scientific and political institutions for public engagement and the substantive value of public participation, leaving a limited role for the public in space policymaking. © The Author(s) 2015.

SO(d,d) transformations of Ramond-Ramond fields and space-time spinors

International Nuclear Information System (INIS)

Hassan, S.F.

2000-01-01

We explicitly construct the SO(d,d) transformations of Ramond-Ramond field strengths and potentials, along with those of the space-time supersymmetry parameters, the gravitinos and the dilatinos in type-II theories. The results include the case when the SO(d,d) transformation involves the time direction. The derivation is based on the compatibility of SO(d,d) transformations with space-time supersymmetry, which automatically guarantees compatibility with the equations of motion. It involves constructing the spinor representation of a twist that an SO(d,d) action induces between the local Lorentz frames associated with the left- and right-moving sectors of the worldsheet theory. The relation to the transformation of R-R potentials as SO(d,d) spinors is also clarified

Thomaier, Susanne; Könecke, Benjamin; Zedda, Roberto; Stabilini, Stefano

2013-01-01

Time has become an increasingly important topic in urban studies and urban planning. The spatial-temporal interplay is not only of relevance for the theory of urban development and urban politics, but also for urban planning and governance. The space-time approach focuses on the human being with its various habits and routines in the city. Understanding and taking those habits into account in urban planning and public policies offers a new way to improve the quality of life in our cities. Adapting the supply and accessibility of public spaces and services to the inhabitants’ space-time needs calls for an integrated approach to the physical design of urban space and to the organization of cities. In the last two decades the body of practical and theoretical work on urban space-time topics has grown substantially. The book offers a state of the art overview of the theoretical reasoning, the development of new analytical tools, and practical experience of the space-time design of public cities in major Europea...

Transformers: Shape-Changing Space Systems Built with Robotic Textiles

Stoica, Adrian

2013-01-01

Prior approaches to transformer-like robots had only very limited success. They suffer from lack of reliability, ability to integrate large surfaces, and very modest change in overall shape. Robots can now be built from two-dimensional (2D) layers of robotic fabric. These transformers, a new kind of robotic space system, are dramatically different from current systems in at least two ways. First, the entire transformer is built from a single, thin sheet; a flexible layer of a robotic fabric (ro-fabric); or robotic textile (ro-textile). Second, the ro-textile layer is foldable to small volume and self-unfolding to adapt shape and function to mission phases.

Leading the Public Face of Space

The National Aeronautics and Space Administration (NASA) is fully committed to sharing the excitement of America's international space missions with its stakeholders, particularly the general public. In 2009, the Space Shuttle delivered astronauts to the Hubble Space Telescope to service that great observatory and to the International Space Station to install the observation platform on the Japanese Kibo laboratory. The Lunar Reconnaissance Orbiter is showing an unprecedented view of the Moon, confirming the presence of hardware left behind during the Apollo missions decades ago and helping scientists better understand Earth's natural satellite. These and numerous other exciting missions are fertile subjects for public education and outreach. NASA's core mission includes engaging the public face of space in many forms and forums. Agency goals include communicating with people across the United States and through international opportunities. NASA has created a culture where communication opportunities are valued avenues to deliver information about scientific findings and exploration possibilities. As this presentation will show, NASA's leaders act as ambassadors in the public arena and set expectations for involvement across their organizations. This presentation will focus on the qualities that NASA leaders cultivate to achieve challenging missions, to expand horizons and question "why". Leaders act with integrity and recognize the power of the team multiplier effect on delivering technical performance within budget and schedule, as well as through participation in education and outreach opportunities. Leaders are responsible for budgeting the resources needed to reach target audiences with compelling, relevant information and serve as role models, delivering key messages to various audiences. Examples that will be featured in this presentation include the Student Launch Projects and Great Moonbuggy race, which reach hundreds of students who are a promising

Discrete Fourier Transform Analysis in a Complex Vector Space

Science.gov (United States)

Dean, Bruce H.

2009-01-01

Alternative computational strategies for the Discrete Fourier Transform (DFT) have been developed using analysis of geometric manifolds. This approach provides a general framework for performing DFT calculations, and suggests a more efficient implementation of the DFT for applications using iterative transform methods, particularly phase retrieval. The DFT can thus be implemented using fewer operations when compared to the usual DFT counterpart. The software decreases the run time of the DFT in certain applications such as phase retrieval that iteratively call the DFT function. The algorithm exploits a special computational approach based on analysis of the DFT as a transformation in a complex vector space. As such, this approach has the potential to realize a DFT computation that approaches N operations versus Nlog(N) operations for the equivalent Fast Fourier Transform (FFT) calculation.

Communicating space weather to policymakers and the wider public

Science.gov (United States)

Ferreira, Bárbara

2014-05-01

As a natural hazard, space weather has the potential to affect space- and ground-based technological systems and cause harm to human health. As such, it is important to properly communicate this topic to policymakers and the general public alike, informing them (without being unnecessarily alarmist) about the potential impact of space-weather phenomena and how these can be monitored and mitigated. On the other hand, space weather is related to interesting phenomena on the Sun such as coronal-mass ejections, and incorporates one of the most beautiful displays in the Earth and its nearby space environment: aurora. These exciting and fascinating aspects of space weather should be cultivated when communicating this topic to the wider public, particularly to younger audiences. Researchers have a key role to play in communicating space weather to both policymakers and the wider public. Space scientists should have an active role in informing policy decisions on space-weather monitoring and forecasting, for example. And they can exercise their communication skills by talking about space weather to school children and the public in general. This presentation will focus on ways to communicate space weather to wider audiences, particularly policymakers. It will also address the role researchers can play in this activity to help bridge the gap between the space science community and the public.

Image Enhancement In HSI Space Using Wavelet Transform

Bansal, Sonia; Malhotra, Deepti

2010-11-01

Image processing modifies images to improve them (enhancement, restoration), extract information (analysis, recognition), and change their structure (composition, image editing). Image Enhancement is simple and most appealing area among all the digital image processing techniques. The main purpose of image enhancement is to bring out detail that is hidden in an image or to increase contrast in a low contrast image [1]. The color restoration functions of some real color image enhancement algorithms are greatly at random and not proved , and the real color images enhanced which are based on illumination-reflectance model have the loss of details and the `halos', we proposed a new algorithm to overcome these disadvantages. Firstly, we transform the real color image from RGB space to HSI space which is approximately orthonormal system. Secondly, the illumination and the reflectance of value are separated by homomorphic filtering based on illumination-reflectance model. We have discovered that the high dynamic range of image including high bright lights is mainly caused by the reflectance. Thirdly, the details of reflectance are preserved by wavelet transform. Fourthly, the dynamic range of reflectance is compressed by Butterworth filtering. Lastly, the energy of the saturation of real color image in HSI space is attenuated according to the spectral sensitivity of most human vision.

Public open spaces such as parks and green spaces are key built environment elements within neighbourhoods for encouraging a variety of physical activity behaviours. Over the past decade, there has been a burgeoning number of active living research studies examining the influence of public open space on physical activity. However, the evidence shows mixed associations between different aspects of public open space (e.g., proximity, size, quality) and physical activity. These inconsistencies hinder the development of specific evidence-based guidelines for urban designers and policy-makers for (re)designing public open space to encourage physical activity. This paper aims to move this research agenda forward, by identifying key conceptual and methodological issues that may contribute to inconsistencies in research examining relations between public open space and physical activity.

Full Text Available The aim of this article was to explore the association between access to public spaces and physical activity for adult women, controlling and testing interactions with sociodemographic and public spaces characteristics. We combined sociodemographic data from a survey with the adult (18-65 years of age women population of Tijuana, Mexico, conducted in 2014 (N = 2,345; with data from a 2013 study on public spaces in the same city. We evaluated access to public spaces by the presence and total area of public spaces in buffers of 400, 800, 1,000 and 1,600m around the participants’ homes. We measured physical activity with the short version of the International Physical Activity Questionnaire (IPAQ-short. We employed multinomial logistic models to evaluate the association between access to public spaces and physical activity, and tested for interactions between access to public spaces and public spaces quality and sociodemographic characteristics. We observed no interaction between access to public spaces and public spaces quality in their effect on physical activity. There was an association between the presence of public spaces in the 400m buffer, and higher odds of being in the low physical activity level (as opposed to being in the moderate level (coefficient: 0.50; 95%CI: 0.13; 0.87. Participants who used public transport were less likely to be in the low physical activity level (coefficient: -0.57; 95%CI: -0.97; -0.17. We suggest that, in this population, the access to public spaces might be less relevant for physical activity than other elements of the urban environment and sociodemographic characteristics.

We present a study on linear canonical transformation in the framework of a phase space representation of quantum mechanics that we have introduced in our previous work. We begin with a brief recall about the so called phase space representation. We give the definition of linear canonical transformation with the transformation law of coordinate and momentum operators. We establish successively the transformation laws of mean values, dispersions, basis state and wave functions.Then we introduce the concept of isodispersion linear canonical transformation.

Public open space landscape plays important role in Bogor Heritage City. Although these spaces can carry various kind of public activities and enhance environment quality, they are fragile to disturbance and changing due to city development. Therefore, as an effort to maintain public open space landscape in 8 zones within Heritage City of Bogor, management of public open space landscape is necessary. Syntesys of public open space landscape management had held by using Analytical Hierarchy Process (AHP). The AHP result showed public open space landscape in Palace and Botanical Garden of Bogor zone (20%) is in high priority to be maintained. The other zone are Situ Gede (16,9%), Plan Karsten (12,3%), European Settlement (12%), Suryakencana (11,2%), Batu Tulis (10,2%), Empang (9.2%) and West Development (8,2%). Ecological function (34,8%) becomes the most important function to be maintained (34.8%) then social culture (31.2%), economic (17%), and aesthetics (17%).

Transformational leadership in the South African public service after the April 2009 national elections

Manasseh M. Mokgolo

2012-04-01

Full Text Available Orientation: The implementation of transformational leadership in public services after national elections has been well recorded in other parts of the world. However, this is not the case in South Africa. Research purpose: The purpose of the study is to determine whether transformational leadership has a beneficial relationship with subordinate leadership acceptance, job performance and job satisfaction. Motivation for the study: Leadership is a critical issue that the public sector needs to address in order to survive and succeed in today’s unstable environment. According to Groenewald and Ashfield (2008, transformational leadership could reduce the effects of uncertainty and change that comes with new leaders and help employees to achieve their objectives. Research design, approach and method: The sample comprised 1050 full-time employees in the public sector based in head offices. The measuring instruments included the Multifactor Leadership Questionnaire (MLQ, the Leadership Acceptance Scale (LAS, the Job Satisfaction Survey (JSS and the Job Performance Survey (JPS. Main findings: Transformational leadership had a positive correlation with subordinate leadership acceptance, performance and job satisfaction. Practical/managerial implications: Managers can train public sector leaders to be transformational leaders because of the adverse effect lack of transformation can have on employees’ attitudes in areas like satisfaction, performance and commitment. Contribution/value-add: This study makes an important contribution to our understanding of transformational leadership processes and to how the public service can improve its practices in order to render quality service to South Africans.

Universal design of public open spaces

Directory of Open Access Journals (Sweden)

Petra Krajner

2008-01-01

Full Text Available Urban open spaces are public places that must assure access for all users. They should be designed for equal use despite disabilities and special recreational needs. Their design must be functional and must meet user’s special requirements, either everyday functional or special (recreational needs. It is not just about overcoming architectural obstacles by building ramps of suitable slope and size; it is about inclusive, universal landscape design of urban space made for all citizens. For this matter, different ways of public use for each group of users is defined, functional criteria are determined, and examples of good and bad design are assembled to present the differences between technically accomplished ramps, and slope paths that include quality landscape inclusive design. To prove the unsuitability of public open spaces in Ljubljana, various analyses were made, including the measurement of steepness, lengths and wideness of certain urban elements. As an application of results, the universal designing principles are summarized in new proposal for entrance into Tivoli Park.

Urban public space materials. Maintenance and design?

Directory of Open Access Journals (Sweden)

Manuel Iglesias Campos

2016-10-01

Full Text Available In this paper, certain aspects related to the conservation of materials commonly used in the design of public spaces are analysed and discussed from a starting point of maintenance definition. The main area of discussion is whether materials selection for pavements and urban furniture, and their placement in the designed space, take into account their maintenance needs. Here the definition of maintenance is the cleaning and repair done by municipal services that is always necessary after construction. From certain examples it can be concluded that, in several cases, the form, the organization and the distribution of the different elements within the public space can cause difficulties for its appropriate conservation, giving rise to alterations and consequently having a negative impact on the durability of this space.

Social Aspects of “Absent Presence” in the Use of Mobile Phones in Public Urban Spaces

Directory of Open Access Journals (Sweden)

Krešimir Katić

2014-12-01

Full Text Available This paper explores how, in the context of the increasing mediated permeability of the boundaries between the realms of home, privacy, in public, work and leisure, people use mobile phones to communicate with absent others whilst in public urban spaces, near others who are physically present, that is, how people negotiate place and presence when “on the phone”. Our ethnographic research of quotidian practices employed by mobile phone users in public spaces in Zagreb, Croatia, confirms that the critique put forward by some media scholars that media technologies create a homogenous, placeless world, is rather exaggerated. Place is reconstituted through a variety of ethnomethodological, and culturally specific practices which we refer to as manoeuvres of spatial juggling, practices which allow people to integrate their presence in the physical and in the virtual worlds. We identify a number of such practices, and also highlight which moral, cognitive and ritual components of micro interactions in public are challenged during mobile phone use. We conclude that, though significantly contingent and fluid, mobile phone interactions do not annihilate place but transform it into an “absent presence”.

Ethics and public integrity in space exploration

Science.gov (United States)

Greenstone, Adam F.

2018-02-01

This paper discusses the National Aeronautics and Space Administration's (NASA) work to support ethics and public integrity in human space exploration. Enterprise Risk Management (ERM) to protect an organization's reputation has become widespread in the private sector. Government ethics law and practice is integral to a government entity's ERM by managing public sector reputational risk. This activity has also increased on the international plane, as seen by the growth of ethics offices in UN organizations and public international financial institutions. Included in this area are assessments to ensure that public office is not used for private gain, and that external entities are not given inappropriate preferential treatment. NASA has applied rules supporting these precepts to its crew since NASA's inception. The increased focus on public sector ethics principles for human activity in space is important because of the international character of contemporary space exploration. This was anticipated by the 1998 Intergovernmental Agreement for the International Space Station (ISS), which requires a Code of Conduct for the Space Station Crew. Negotiations among the ISS Partners established agreed-upon ethics principles, now codified for the United States in regulations at 14 C.F.R. § 1214.403. Understanding these ethics precepts in an international context requires cross-cultural dialogue. Given NASA's long spaceflight experience, a valuable part of this dialogue is understanding NASA's implementation of these requirements. Accordingly, this paper will explain how NASA addresses these and related issues, including for human spaceflight and crew, as well as the development of U.S. Government ethics law which NASA follows as a U.S. federal agency. Interpreting how the U.S. experience relates constructively to international application involves parsing out which dimensions relate to government ethics requirements that the international partners have integrated into the

Today the city is presented as a set of discontinuous fragments, which return an image of plural spaces, places and non-places, past and present. Disappearing borders, perimeters, which marked the places, neighborhoods are uncommon spaces, undefined areas between built and unbuilt. The square is the gap in the building density; it has lost its significance as a place of socialization. The recent planning instruments (plans and programs that belong to the city of Rotterdam are geared to transform the city into a “child-friendly city" (city suitable for children, the city attracts young couples and middle-class families just for the fact that the city is distancing itself from the modernist planning based on the zoning and is encouraging the mix of urban functions; particular emphasis in this phase of planning and urban design is given by the statement of the urban Vision Rotterdam 2030.

The spaces in which drug use occurs constitutes a key aspect of the "risk environment" of people who inject drugs (PWID). We aimed to add nuance to the characterization of "safe" and "unsafe" spaces in PWID's environments to further understand how these spaces amplify the risk of morbidities associated with injection drug use. PWID were recruited through the Baltimore City syringe service program and through peer referral. Participants completed a socio-behavioral survey. Multivariable logistic regression was used to identify associations between utilization of public, semi-public and private spaces with arrest, non-fatal overdose, and receptive syringe sharing. The sample of PWID (N = 283) was mostly 45 years and older (54%), male (69%), Black (55%), and heroin users (96%). Compared to PWID who primarily used private settings, the adjusted odds of recent overdose were greater among PWID who mostly used semi-public and public locations to inject drugs. We also found independent associations between arrest and semi-public spaces, and between receptive syringe sharing and public spaces (all p spaces where PWID can reduce their risk of overdose, likelihood of arrest and blood-borne diseases, and the dual potential of the environment in promoting health and risk.

Full Text Available Public space takes many spatial forms, including parks, the streets, sidewalks and footpaths that connect an edge of a space between buildings or roadsides, hence are important spaces in an urban setting. In a city context, the public space frames the city image. Kuala Lumpur’s public spaces are typically made up of shopping streets. It allows an ambivalent space that encourages more activities and interactions through the continuity of the street. For that reason, street that brings out life and movement in an urban space is an ideal type of street. In maintaining public spaces and reinventing it, placemaking is a quest for engagement tool to help strengthening legal frameworks in order to protect the public space which is seen viable at a city level. This paper therefore, explores the potentials of public spaces and its management. It applies the case study method by means of investigating two areas in the city encompassing similar characteristics. Generally, the research is designed to test the theoretical framework in managing the public space and its key dimensions in shaping the quality of public space. The researcher then synthesizes the broad range of development of placemaking and the changing uses of public space. The findings will advance further understanding of a suitable application thus intensify the legal framework that shapes the quality of space and its management.

Safety management and public spaces: restoring balance.

Science.gov (United States)

Ball, David J; Ball-King, Laurence

2013-05-01

Since 2000, the reputation of health and safety in the United Kingdom has been tarnished, so much so that it has become the subject of both a media circus and a government inquiry. This not only threatens the worthy goals of health and safety, but also impacts upon the associated tool of risk assessment itself such that "risk assessment" is increasingly seen by the public at large as a term inviting ridicule, even abuse. The main thrust of the government's examination of health and safety has been its concern that safety requirements were placing a disproportionate burden on business. However, there is another source of discontent, which is public chagrin over the impact of injury control measures upon life beyond the conventional workplace, in particular upon the public spaces that people frequent in their leisure time and on the activities they engage in there. This article provides a perspective on this second dimension of the crisis in confidence. It describes how many U.K. agencies with responsibilities for a wide portfolio of public amenities ranging from the provision of play spaces for the young to the management of publicly accessible countryside, the maintenance of urban and rural trees, the stewardship of sites of cultural heritage, and the pursuit of outdoor educational activities have responded to some conflicts posed to their services by the new safety culture. It concludes with a discussion of implications for the management of public space and for risk assessment itself. © 2012 Society for Risk Analysis.

Laughter and collective awareness: The cinema auditorium as public space

Directory of Open Access Journals (Sweden)

Julian Hanich

2014-12-01

Full Text Available This article looks at how the collective experience of laughter in the movie theater is related to the idea of the cinema as a public space. Through the nonverbal expression of laughter the audience ‘constructs’ a public space the viewers may not have been aware of to the same degree prior to the collective public expression. Moreover, the public space created through laughter allows for an expedient type of monitoring: inappropriate laughter may be exposed in front of others. With viewers who laugh approvingly about racist violence or misogynist jokes, we can easily lay bare the ethical implications.

ICTs as a Tool to Increase the Attractiveness of Public Spaces

Directory of Open Access Journals (Sweden)

Reinhold Lehel Stadler

2013-10-01

Full Text Available Nowadays, ICTs is one of the major factors influencing urban development. Consequently, public spaces – an important urban subsystem – are shaped by interaction with the new technologies. This paper aims to present the ways, in which different ICT tools can increase the attractiveness and competitiveness of public spaces, in opposition to several approaches stating that technologies can only encourage segregation of individuals. The article is focused on possibilities to open the public realm for functions and activities that are usually regarded as private. The major roles that ICTs can play in the public space are: education, information, art and entertainment. Based on this classification various examples and proposals of ICTs interventions in public spaces are presented and analysed, including the Zaragoza’s Digital Mile, the Cloud at Athens and the concept of Flux Space. The specificity of this paper rests on a constant parallel drawn between the interventions around the globe and Romania, aiming to highlight the potential for competitiveness of Romanian public spaces, as a result of using various ICTs tools.

Eriawan, Tomi; Setiawati, Lestari

2017-06-01

Padang City as a big city with a population approaching one million people has to address the issue of increased activities of the population and increased need for land and space for those activities. One of the effects of population growth and the development of activities in Padang is the decreasing number of open spaces for the outdoor public activities, both the natural and artificial public. However, Padang City has several open spaces that are built and managed by the government including 40 units of open spaces in the form of plansum parks, playgrounds, and sports parks, with a total area of 10.88 hectares. Despite their status as public open spaces, not all of them can be used and enjoyed by the public since most of them are passive parks, in which they are made only as a garden without any indulgences. This study was performed to assess the quality of public spaces in the central business of Padang City, namely Imam Bonjol Park (Taman Imam Bonjol). The methods of this study were done through several stages, which were to identify the typology of function space based on [1] Carmona (2008) and to assess the space utilization index based on the approach of Public Space Index according to Mehta [2] (2007). The purpose of this study was to assess the quality of space which is a public space in Padang City. The space quality was measured based on the variables in Good Public Space Index, the intensity of use, the intensity of social activity, the duration of activity, the variations in usage, and the diversity of use. The rate of the index of public space quality at Taman Imam Bonjol was determined by assessing 5 (five) variables of space quality. Based on the results of the analysis, public space utilization index was equal to 0.696. This result could be used to determine the quality of public space, in this case was Imam Bonjol Park was in Medium category. The parameters indicated several results including the lack of diversity in users' activity time, less

Some aspects of transformation of the nonlinear plasma equations to the space-independent frame

International Nuclear Information System (INIS)

Paul, S.N.; Chakraborty, B.

1982-01-01

Relativistically correct transformation of nonlinear plasma equations are derived in a space-independent frame. This transformation is useful in many ways because in place of partial differential equations one obtains a set of ordinary differential equations in a single independent variable. Equations of Akhiezer and Polovin (1956) for nonlinear plasma oscillations have been generalized and the results of Arons and Max (1974), and others for wave number shift and precessional rotation of electromagnetic wave are recovered in a space-independent frame.

EMERGING CHALLENGES IN THE MANAGEMENT OF CONTEMPORARY PUBLIC SPACES IN URBAN NEIGHBOURHOODS

Directory of Open Access Journals (Sweden)

Rajjan Man Chitrakar

2017-03-01

Full Text Available The lack of management has led to the degrading quality of public space in modern cities around the globe. Contemporary public spaces are facing challenges in terms of maintaining them as a “social space” so that they are accessible and functional for the users. Using Kathmandu as a case study, this paper explores the challenges the contemporary public spaces within urban neighbourhoods are facing in their management. The study reveals that the regulation of use is a major concern of public space management in the new neighbourhoods of Kathmandu as evident in the limited accessibility and utility of public space, due to control and commercialisation. The use of public space has also been affected by the lack of regular maintenance. The root cause of these problems lies in weak urban governance at the neighbourhood level, which has led the local community-based organisations to take a role in neighbourhood management. These findings confirm that the management of public space is a critical issue of urban development with commonalities existing across geographical regions that demand adequate consideration from the stakeholders.

Public Space in Barcelona (1992-2017) - Evolution and Case Studies

Science.gov (United States)

Sanfeliu Arboix, Ignacio; Martín, Estefanía

2017-10-01

The construction of the public space has become in the last decades something so important and fundamental in the architecture of the cities, that requires a specific discipline and a concrete study that evaluates the characteristics and actions on it. Not already from an urbanistic perspective but from its own design and constructive perspective, with its character as a place for everyone and for everything, must gather a series of elements that are unique to this space. Barcelona is one of the densest cities in the world that, since the end of the s. XX until our days, tries to solve the public space with a design of quality and optimum. The shortage of public space, which also hosts more than eight million tourists each year, makes it necessary to propose a type of meticulous intervention in order to accommodate all types of users and activities. From the first Universal Exhibition of 1888 through 1929 to the 1992 Olympics as the most important stimulus for this renewal of urban space, Barcelona has been rethinking and evolving in the modus operandi in terms of its urban space. From our professional experience as architects both in the municipal, private and university spheres, we believe that it is our responsibility to confer the public space, that is to say, the design of the urban infrastructure with the attributes necessary to consolidate it in a space Suitable for all without exception and as a place of expression of citizenship. Through the projects of public space developed in our office we will analyze this change of procedure in the construction of squares, parks and other spaces in the city of Barcelona.

URBAN COHESION: A PUBLIC SPACE NETWORK ASSESSMENT

Directory of Open Access Journals (Sweden)

Ana Júlia Pinto

2015-07-01

With this in mind, we have analysed one study case in Barcelona – the Barceloneta neighbourhood, a historic quarter outside the old walled city that is now part of its consolidated urban fabric. The analysis of this case allows us to assess both (1 the role that the urban layout plays in the configuration of the public space network, forcing us to reflect on the role of “boundaries” as fundamental elements in the articulation among the local and overall public space networks in the city; and (2 the role of several socio-economic dynamics affecting to the everyday life of these neighbourhoods

2017-12-01

The lack of public space is one of the main problems in the big cities in Indonesia. Urban kampungas part of the city is also no exception. Rapid growth on population sparks uncontrollable physical development that erode open space inside urbankampung. Sometimes, what is left is just neglected space which don‟t „live‟ and far from the definition of public space. Mural art has been existed since the beginning of human civilization. Now, it has evolved into one of the popular urban art. The previous research has proven that the process of urban art making through participatory approach could trigger community interaction in a space. Interaction itself is a main factor that may trigger the establishmentof a public space. With the same method, this research attempts to build mural in a neglected space inside urbankampung named Palsigunung. After all of the process done, the space still haven‟t changed from the previous condition, which is still a neglected space. Together with facilitator, kampung‟s residents need to be involved identifying the problem and also the solution to the lack of public space in their kampung. Particularly for urban kampungPalsigunung, the needed solution might not be mural.

The quantum state vector in phase space and Gabor's windowed Fourier transform

International Nuclear Information System (INIS)

Bracken, A J; Watson, P

2010-01-01

Representations of quantum state vectors by complex phase space amplitudes, complementing the description of the density operator by the Wigner function, have been defined by applying the Weyl-Wigner transform to dyadic operators, linear in the state vector and anti-linear in a fixed 'window state vector'. Here aspects of this construction are explored, and a connection is established with Gabor's 'windowed Fourier transform'. The amplitudes that arise for simple quantum states from various choices of windows are presented as illustrations. Generalized Bargmann representations of the state vector appear as special cases, associated with Gaussian windows. For every choice of window, amplitudes lie in a corresponding linear subspace of square-integrable functions on phase space. A generalized Born interpretation of amplitudes is described, with both the Wigner function and a generalized Husimi function appearing as quantities linear in an amplitude and anti-linear in its complex conjugate. Schroedinger's time-dependent and time-independent equations are represented on phase space amplitudes, and their solutions described in simple cases.

Towards Culture 3.0 - Performative space in the public library

Jochumsen, Henrik; Skot-Hansen, Dorte; Rasmussen, Casper Hvenegaard

2015-01-01

The aim of this article is to analyse and discuss the development of performative spaces in public libraries from a cultural policy perspective. First, a framework of three concepts of culture, 1.0–3.0, is used as a tool to analyse the overall development of public libraries. Against...... this background, we introduce the notion of performative spaces in public libraries by highlighting Nordic examples. The tendency can also be seen on a broader level in European and North American libraries, where a ‘performative turn’ can be seen as the relationship between the library and its users, especially...... the younger ‘digital natives’. The rationales behind the emergence of performative spaces in public libraries are analysed and discussed: democratisation, empowerment and economic impact. This article concludes that the performative spaces are legitimized by multiple rationales in the same way as cultural...

Major health service transformation and the public voice: conflict, challenge or complicity?

Science.gov (United States)

Martin, Graham P; Carter, Pam; Dent, Mike

2018-01-01

Objectives Calls for major reconfigurations of health services have been accompanied by recommendations that wide ranging stakeholders be involved. In particular, patients and the wider public are seen as critical contributors as both funders and beneficiaries of public health care. But public involvement is fraught with challenges, and little research has focused on involvement in the health service transformation initiatives. This paper examines the design and function of public involvement in reconfiguration of health services within the English NHS. Methods Qualitative data including interviews, observation and documents were collected in two health service 'transformation' programmes; interviews include involved public and professional participants. Data were analysed using parallel deductive and inductive approaches. Results Public involvement in the programmes was extensive but its terms of reference, and the individuals involved, were restricted by policy pressures and programme objectives. The degree to which participants descriptively or substantively represented the wider public was limited; participants sought to 'speak for' this public but their views on what was 'acceptable' and likely to influence decision-making led them to constrain their contributions. Conclusions Public involvement in two major service reconfiguration programmes in England was seen as important and functional, and could not be characterized as tokenistic. Yet involvement in these programmes fell short of normative ideals, and could inadvertently reduce, rather than enlarge, public influence on health service reconfiguration decisions.

2015-12-01

Full Text Available The last 25 years have been in many Polish cities a period of intensive modernization and renewals of the existing public spaces. Most of all the resurfacing of the pavement and changing of street furniture have been held. In many cases, the transformations in the urban areas were integrated with exclusion from traffic. The question arises what criteria architects or landscape architects follow and what design solutions apply. It is also interesting how the new shape of the floor in public spaces (understood here as a pavement and street furniture together can help to create integrating and activating space for residents. And how it can affect the quality of life in a wider area. This article attempts to answer these questions based on new solutions on Kosciuszko Square in Białystok, executed in 2005-2009.

Proximity to public open space, such as parks and other green spaces, has considerable health benefits, and people have been shown to be more likely to use such space for physical activity if it is of high quality. This paper describes a new remote-assessment approach that makes use of Google Earth Pro (the free version of this program is Google Earth) to provide rapid and inexpensive measurement of the quality of public open space. The aim of the study was to assess the correlation between assessments of the quality of public open space using (1) the remote method (making use of Google Earth Pro) and (2) direct observation with a well-established measure of quality, the Public Open Space Tool (POST). Fifty parks selected from the southwest part of Sydney, Australia, were assessed in 2009 with the remote method (using Google Earth Pro), and scores were compared with those obtained from direct observation of the same parks using POST. The time taken to conduct the assessments using each method was also recorded. Raters for each method were blind to scores obtained from using the other method. Analyses were conducted in 2009. The Spearman correlation coefficient between the quality scores obtained for the 50 parks using the remote method and direct observation was 0.9 (pspaces without the need for in-person visits, dramatically reducing the time required for environmental audits of public open space.

Using futures methods to create transformative spaces: visions of a good Anthropocene in southern Africa

Directory of Open Access Journals (Sweden)

Laura M. Pereira

2018-03-01

Full Text Available The unique challenges posed by the Anthropocene require creative ways of engaging with the future and bringing about transformative change. Envisioning positive futures is a first step in creating a shared understanding and commitment that enables radical transformations toward sustainability in a world defined by complexity, diversity, and uncertainty. However, to create a transformative space in which truly unknowable futures can be explored, new experimental approaches are needed that go beyond merely extrapolating from the present into archetypal scenarios of the future. Here, we present a process of creative visioning where participatory methods and tools from the field of futures studies were combined in a novel way to create and facilitate a transformative space, with the aim of generating positive narrative visions for southern Africa. We convened a diverse group of participants in a workshop designed to develop radically different scenarios of good Anthropocenes, based on existing "seeds" of the future in the present. These seeds are innovative initiatives, practices, and ideas that are present in the world today, but are not currently widespread or dominant. As a result of a carefully facilitated process that encouraged a multiplicity of perspectives, creative immersion, and grappling with deeply held assumptions, four radical visions for southern Africa were produced. Although these futures are highly innovative and exploratory, they still link back to current real-world initiatives and contexts. The key learning that arose from this experience was the importance of the imagination for transformative thinking, the need to capitalize on diversity to push boundaries, and finally, the importance of creating a space that enables participants to engage with emotions, beliefs, and complexity. This method of engagement with the future has the potential to create transformative spaces that inspire and empower people to act toward positive

Transforming phylogenetic networks: Moving beyond tree space.

Science.gov (United States)

Huber, Katharina T; Moulton, Vincent; Wu, Taoyang

2016-09-07

Phylogenetic networks are a generalization of phylogenetic trees that are used to represent reticulate evolution. Unrooted phylogenetic networks form a special class of such networks, which naturally generalize unrooted phylogenetic trees. In this paper we define two operations on unrooted phylogenetic networks, one of which is a generalization of the well-known nearest-neighbor interchange (NNI) operation on phylogenetic trees. We show that any unrooted phylogenetic network can be transformed into any other such network using only these operations. This generalizes the well-known fact that any phylogenetic tree can be transformed into any other such tree using only NNI operations. It also allows us to define a generalization of tree space and to define some new metrics on unrooted phylogenetic networks. To prove our main results, we employ some fascinating new connections between phylogenetic networks and cubic graphs that we have recently discovered. Our results should be useful in developing new strategies to search for optimal phylogenetic networks, a topic that has recently generated some interest in the literature, as well as for providing new ways to compare networks.

Comparison Of Planar And Wound Transformers For Flyback Forward And Half-Bridge Space Power Converters

Science.gov (United States)

Bjorklund, Thomas; Andreasen, John; Brosen, Finn; Matthiesen, Erik; Poulsen, Ole

2011-10-01

Planar technology has now entered the space domain. The big advantages of planar technology are; - Low profile - Excellent repeatability - Economical assembly - Mechanical integrity - Superior thermal characteristics This is why the general power industries increasingly are using planar magnetics in more and more applications, and therefore also why we see a rising demand for the usability of the planar technology among space application developers. The differences between wound and planar transformers have been mapped with a detailed look on the various parasitic component values, such as DC- and AC- resistance, Leakage Inductance and stray capacitance, and revealed the magnitude of the advantages of planar technology. This technical solution is proven in prototypes that have been built in different combination of PCB's and copper foil, with more or less interleaving of windings. Furthermore the transformers have been designed with several outputs stacked together with a fairly high number of primary turns, in order to have planar transformers similar to the wound types that are generally used for space applications.

The Evaluation of the Equipment and Quality of the Public Space of Poznań

Directory of Open Access Journals (Sweden)

Budner Waldemar W.

2016-06-01

Full Text Available The article defines the notion of public space and attempts to explain its forms and roles. The article realizes two cognitive goals: the evaluation of the equipment of public spaces in Poznań with the selected elements of landscape architecture and the quality of those spaces. Empirical research was conducted in the form of a survey addressed at 300 respondents. The research activities conducted in the course of work allow for the formulation of the following conclusions: the quality of life in a city depends on the condition of equipment of public space; the elements of landscape architecture make the public space of Poznań more attractive (contribute to its functionality, increase the aesthetics of urban space; the condition of the equipment of public space with landscape architecture is evaluated as good; the users of the public space in Poznań pointed out the problem of advertising pillars, advertisements and signboards, public toilets and the insufficient number of seats.

Space Culture: Innovative Cultural Approaches To Public Engagement With Astronomy, Space Science And Astronautics

Science.gov (United States)

Malina, Roger F.

2012-01-01

In recent years a number of cultural organizations have established ongoing programs of public engagement with astronomy, space science and astronautics. Many involve elements of citizen science initiatives, artists’ residencies in scientific laboratories and agencies, art and science festivals, and social network projects as well as more traditional exhibition venues. Recognizing these programs several agencies and organizations have established mechanisms for facilitating public engagement with astronomy and space science through cultural activities. The International Astronautics Federation has established an Technical Activities Committee for the Cultural Utilization of Space. Over the past year the NSF and NEA have organized disciplinary workshops to develop recommendations relating to art-science interaction and community building efforts. Rationales for encouraging public engagement via cultural projects range from theory of creativity, innovation and invention to cultural appropriation in the context of `socially robust science’ as advocated by Helga Nowotny of the European Research Council. Public engagement with science, as opposed to science education and outreach initiatives, require different approaches. Just as organizations have employed education professionals to lead education activities, so they must employ cultural professionals if they wish to develop public engagement projects via arts and culture. One outcome of the NSF and NEA workshops has been development of a rationale for converting STEM to STEAM by including the arts in STEM methodologies, particularly for K-12 where students can access science via arts and cultural contexts. Often these require new kinds of informal education approaches that exploit locative media, gaming platforms, artists projects and citizen science. Incorporating astronomy and space science content in art and cultural projects requires new skills in `cultural translation’ and `trans-mediation’ and new kinds

The dimensions of urban public space in user’s mental image

Directory of Open Access Journals (Sweden)

Matej Nikšič

2006-01-01

Full Text Available The article presents a method for recognising qualitative and quantitative dimensions of open urban space in the user’s perceptual image. It stems from the hypothesis that the open urban space in mental perception isn’t a uniform continuum, which in general applies to its physical phenomenon. It discloses where and how users experience the limits of real open public space that they occupy and what they perceive as the neighbourhood of such a place. Therefore it researches rules applied by the user to mentally structure physically continuous space into smaller units and then reassemble these into a network. Knowledge of such rules enables expansion of open urban public spaces, which user’s experience as positive, into the wider area, thus revitalising those neighbouring spaces that are perceived as negative or are completely absent in the mental image and consequentially unused. The presence of people is in fact the essential component of quality public spaces.

Non-Abelian bosonization as a nonholonomic transformation from a flat to a curved field space

International Nuclear Information System (INIS)

Kleinert, H.

1997-01-01

There exists a simple rule by which path integrals for the motion of a point particle in a flat space can be transformed correctly into those in a curved space. This rule arose from well-established methods in the theory of plastic deformations, where crystals with defects are described mathematically by applying active nonholonomic coordinate transformations to ideal crystals. In the context of time-sliced path integrals, this has given rise to a quantum equivalence principle which determines the short-time action and functional integration measure of fluctuating orbits in spaces with curvature and torsion. The nonholonomic transformations have a nontrivial Jacobian which in curved spaces produces an additional energy proportional to the curvature scalar, thereby canceling an equal term found earlier by DeWitt in his formulation of Feynman close-quote s time-sliced path integral in curved space. The importance of this cancelation has been documented in various systems (H-atom, particle on the surface of a sphere, spinning top). Here we point out its relevance to the bosonization of a non-Abelian one-dimensional quantum field theory, whose fields live in a flat field space. The bosonized version is a quantum-mechanical path integral of a point particle moving in a space with constant curvature. The additional term introduced by the Jacobian is crucial for the identity between original and bosonized theory. A useful bosonization tool is the so-called Hubbard endash Stratonovich formula for which we find a nonabelian version. copyright 1997 Academic Press, Inc

City project and public space

CERN Document Server

2013-01-01

The book aims at nurturing theoretic reflection on the city and the territory and working out and applying methods and techniques for improving our physical and social landscapes. The main issue is developed around the projectual dimension, with the objective of visualising both the city and the territory from a particular viewpoint, which singles out the territorial dimension as the city’s space of communication and negotiation. Issues that characterise the dynamics of city development will be faced, such as the new, fresh relations between urban societies and physical space, the right to the city, urban equity, the project for the physical city as a means to reveal civitas, signs of new social cohesiveness, the sense of contemporary public space and the sustainability of urban development. Authors have been invited to explore topics that feature a pluralism of disciplinary contributions studying formal and informal practices on the project for the city and seeking conceptual and operative categories capab...

Agency transformation and state public utility commissions

International Nuclear Information System (INIS)

Jones, Douglas N.

2006-01-01

The demise of public utility commissions has been periodically predicted (sometimes hoped for). In their long history they have been attacked by critics as ineffective, inefficient, expensive, or unnecessary. Further, the demonstrated survivability of the commission concept has often been uncharitably attributed to powerful political constituencies, self-preservation manoeuvrings by commissioners themselves, and inertia. The implications of this article point another way. Commission regulation of public utilities has survived mainly because of continued need for social oversight of these critical industry sectors and the capacity of PUCs strategically to adapt to fundamental changes in their surroundings. Two transformational upheavals are treated here - a challenge of flexibility and responsiveness by the dramatic run-up in costs and prices in the 1970s and challenge to relevance by the policy shift to greater reliance on market competition in the 1990s - and regulation's successful accommodation to them. Viewed this way commission regulation is more in a position of 'second wind' than 'last breath'. (author)

Low physical activity levels and high levels of sedentary time among adolescents call for population wide interventions. Public open spaces can be important locations for adolescents' physical activity. This study aimed to describe the prevalence, frequency and context of public open space visitation and to gain insight into the individual, social and physical environmental factors associated with public open space use among 12- to 16-year-old Flemish (Belgian) adolescents. Global positioning system devices, accelerometers and one-on-one interviews were used to measure location-specific activity levels, time spent at, reasons for using and accompaniment at public open spaces among 173 adolescents. Multilevel hurdle and gamma models were used to estimate the associations between the independent variables (age, gender, ethnicity, education, sport club membership and accompaniment) and the amount of time, sedentary time, light-, moderate- to vigorous- and vigorous-intensity physical activity at public open spaces. Three out of four participants had visited a public open space (for recreational purposes) and participants were most often accompanied by friends/classmates. Mainly public transportation stops/stations were used, and subsequently the most reported reason for public open space use was "to wait for something or someone". Furthermore, boys, younger adolescents, non-western-European adolescents and lower educated adolescents were more likely to use public open spaces. Additionally, boys and younger adolescents were more likely to accumulate physical activity at public open spaces. The only social environmental variable associated with time spent at public open spaces was accompaniment by siblings: adolescents spent more time at public open spaces when accompanied by their siblings. Public open spaces may be effective areas to promote physical activity among groups at risk for physical inactivity (i.e. low educated and non-western-European adolescents

Preaching to the converted? An analysis of the UK public for space exploration.

Science.gov (United States)

Entradas, Marta; Miller, Steve; Peters, Hans Peter

2013-04-01

This article presents the results of a survey carried out at two space outreach events in the UK aimed at characterising "the public for space exploration" and measuring public support for space exploration. Attitude towards space exploration and policy preferences were used as measures of public support. The sample involved 744 respondents and was mainly composed of adults between 25 and 45 years old, with men slightly over-represented compared with women. Findings revealed that males appeared to be stronger supporters than females - men had a more positive attitude towards space exploration and stronger space policy preferences. Because mixed groups tend to come together to such events we argue that male respondents would be more likely to be part of the "attentive" and "interested" public who come to outreach activities and bring a less interested public with them.

Community members’ initiatives in public open spaces: two case studies from Slovenia

Directory of Open Access Journals (Sweden)

Sabina Jelenc Krašovec

2017-10-01

Full Text Available The paper deals with public spaces as open, everyday arenas where people share experiences beyond their immediate circle of friends, family and age group. Public space is understood as a forum for social and personal change (Harvey, 2011; Lefebvre, 2013; Arendt, 1996; Habermas, 1989; 2001. Questions are analysed from the point of view of community members, who are strongly attached to the space and who are interested in belonging and in proactive changes in their living environment (Iecovich, 2014; Kohn 2004; Mean and Tims, 2005. The paper is based on the presumptions that public space has an important role in generating ideas and activities of community members and that it is an important venue for community members’ informal learning. Ethnomethodological research in two public spaces (the Tabor community in Ljubljana and a small community in the coastal town of Izola show that there are differences between both public spaces regarding top-down initiatives and bottom-up, self-organized activities. However, although the activity initiators were in one case different associations rooted in the community, and in the other the local people themselves, most of the activities were conducted by people living in the selected communities/public spaces themselves as is typical of grassroots activities. It was confirmed that learning was not often mentioned by members of either community and was mostly a hidden activity, resulting in tacit knowledge.

On Bäcklund transformation and vortex filament equation for null Cartan curve in Minkowski 3-space

Grbović, Milica, E-mail: milica.grbovic@kg.ac.rs; Nešović, Emilija, E-mail: nesovickg@sbb.rs [University of Kragujevac, Faculty of Science, Department of Mathematics and Informatics (Serbia)

2016-12-15

In this paper we introduce Bäcklund transformation of a null Cartan curve in Minkowski 3-space as a transformation which maps a null Cartan helix to another null Cartan helix, congruent to the given one. We also give the sufficient conditions for a transformation between two null Cartan curves in the Minkowski 3-space such that these curves have equal constant torsions. By using the Da Rios vortex filament equation, based on localized induction approximation, we derive the vortex filament equation for a null Cartan curve and obtain evolution equation for it’s torsion. As an application, we show that Cartan’s frame vectors generate new solutions of the Da Rios vortex filament equation.

The effect of public opinion on future space programs is discussed in terms of direct support, apathy, or opposition, and concern about the tax burden, budgetary pressures, and national priorities. Factors considered include: the salience and visibility of NASA as compared with other issues, the sources of general pressure on the federal budget which could affect NASA, the public's opinions regarding the size and priority of NASA'S budget, the degree to which the executive can exercise leverage over NASA's budget through influencing or disregarding public opinion, the effects of linkages to other issues on space programs, and the public's general attitudes toward the progress of science.

Nuclear systems in space? Does/will the public accept them?

Science.gov (United States)

Finger, Harold B.

1993-01-01

Public attitudes toward the use of nuclear energy on earth and in space are discussed. Survey data are presented which show that the public believes nuclear energy should play an important role in our energy supply. However, based on broad attitude research, there should be no expectation that the public will accept or support the use of nuclear energy unless it meets special needs and offers special and significant benefits. It is proposed that a public information program be adopted that results in getting recognition and support for the space program broadly and for the missions that benefit substantially from or require nuclear energy for their accomplishment.

Influence of urban waterfront appearance on public space functions

Directory of Open Access Journals (Sweden)

Iva Hradilová

2012-01-01

Full Text Available Although the issue of urban waterfront is not entirely new, it still represents a very vivid topic. Urban waterfronts have for long been standing in the forefront of many architects and organizations, who are aware of their value and the potential a watercourse carries within the urban interior. A watercourse is an interconnecting element between the urban development and the surrounding countryside and urban waterfronts are the intermediaries of communication. It is exactly in their area where the city - a purely human product with an inner structure and order defined by humans - meets the element of water, which is a purely natural component.What influences the urban structure most is, however, the presence of water in its very basic form i.e. in the form of a river. Its significance and effect on the public space and the inner relations within the body of the settlement vary with the size and the width of the flow, character of the waterfront, architectural layout of the riverbanks and its current utilization. Urban river works as a communication element which meets with the natural features. It seems to be unnatural to define a waterfront space like mono-functional site. This space denies the very essence of the waterfront and the city’s inhabitants appear as unattractive. In this case the very attractive element of water is unable to urban residents to attract together. In general, the quality of the public space is determined by the degree of its utilization by a wider group of inhabitants. It is the inhabitants themselves who imprints the concept of a public space to empty urban spaces.The present form of urban waterfronts is a result of the historical development, attitude and mental state of the society. The architectural appearance of not only the waterfront but also all public spaces is a reflection of the current social values. It gives evidence about the character of the society, the present economic system, the state and thinking

Z-2 Space Suit: A Case Study in Human Spaceflight Public Outreach

Science.gov (United States)

McFarland, Shane M.

2016-01-01

NASA Johnson Space Center's Z-series of planetary space suit prototypes is an iterative development platform with a Mars-forward design philosophy, targeting a Mars surface mission in the mid-2030s. The first space suit assembly, called the Z-1, was delivered in 2012. While meeting the project's stated requirements and objectives, the general public's reception primarily focused on the color scheme, which vaguely invoked similarity to a certain animated cartoon character. The public at large has and continues to be exposed to varying space suit design aesthetics from popular culture and low TRL technology maturation efforts such as mechanical counterpressure. The lesson learned was that while the design aesthetic is not important from an engineering perspective, the perception of the public is important for NASA and human spaceflight in general. For the Z-2 space suit, an integrated public outreach strategy was employed to engage, excite and educate the public on the current technology of space suits and NASA's plans moving forward. The keystone of this strategy was a public vote on three different suit cover layer aesthetics, the winner of which would be used as inspiration in fabrication. Other components included social media, university collaboration, and select media appearances, the cumulative result of which, while intangible in its benefit, was ultimately a positive effect in terms of the image of NASA as well as the dissemination of information vital to dispelling public misconceptions.

Query transformations and their role in Web searching by the members of the general public

2006-01-01

Full Text Available Introduction. This paper reports preliminary research in a primarily experimental study of how the general public search for information on the Web. The focus is on the query transformation patterns that characterise searching. Method. In this work, we have used transaction logs from the Excite search engine to develop methods for analysing query transformations that should aid the analysis of our ongoing experimental work. Our methods involve the use of similarity techniques to link queries with the most similar previous query in a train. The resulting query transformations are represented as a list of codes representing a whole search. Analysis. It is shown how query transformation sequences can be represented as graphical networks and some basic statistical results are shown. A correlation analysis is performed to examine the co-occurrence of Boolean and quotation mark changes with the syntactic changes. Results. A frequency analysis of the occurrence of query transformation codes is presented. The connectivity of graphs obtained from the query transformation is investigated and found to follow an exponential scaling law. The correlation analysis reveals a number of patterns that provide some interesting insights into Web searching by the general public. Conclusion. We have developed analytical methods based on query similarity that can be applied to our current experimental work with volunteer subjects. The results of these will form part of a database with the aim of developing an improved understanding of how the public search the Web.

Conservation of connectivity of model-space effective interactions under a class of similarity transformation

Duan Changkui; Gong Yungui; Dong Huining; Reid, Michael F.

2004-01-01

Effective interaction operators usually act on a restricted model space and give the same energies (for Hamiltonian) and matrix elements (for transition operators, etc.) as those of the original operators between the corresponding true eigenstates. Various types of effective operators are possible. Those well defined effective operators have been shown to be related to each other by similarity transformation. Some of the effective operators have been shown to have connected-diagram expansions. It is shown in this paper that under a class of very general similarity transformations, the connectivity is conserved. The similarity transformation between Hermitian and non-Hermitian Rayleigh-Schroedinger perturbative effective operators is one of such transformations and hence the connectivity can be deducted from each other

We propose a real-space renormalization group method to explicitly decouple into independent components a many-body system that, as in the phenomenon of spin-charge separation, exhibits separation of degrees of freedom at low energies. Our approach produces a branching holographic description of such systems that opens the path to the efficient simulation of the most entangled phases of quantum matter, such as those whose ground state violates a boundary law for entanglement entropy.

In this study, the aim was to develop and test an urban green space indicator for public health, as proposed by the World Health Organisation (WHO) Regional Office for Europe, in order to support health and environmental policies. We defined the indicator of green space accessibility as a proportion of an urban population living within a certain distance from a green space boundary. We developed a Geographic Information System (GIS)-based method and tested it in three case studies in Malmö, Sweden; Kaunas, Lithuania; and Utrecht, The Netherlands. Land use data in GIS from the Urban Atlas were combined with population data. Various population data formats, maximum distances to green spaces, minimum sizes of green spaces, and different definitions of green spaces were studied or discussed. Our results demonstrated that with increasing size of green space and decreased distance to green space, the indicator value decreased. As compared to Malmö and Utrecht, a relatively bigger proportion of the Kaunas population had access to large green spaces, at both shorter and longer distances. Our results also showed that applying the method of spatially aggregated population data was an acceptable alternative to using individual data. Based on reviewing the literature and the case studies, a 300 m maximum linear distance to the boundary of urban green spaces of a minimum size of 1 hectare are recommended as the default options for the indicator. The indicator can serve as a proxy measure for assessing public accessibility to urban green spaces, to provide comparable data across Europe and stimulate policy actions that recognise the importance of green spaces for sustainable public health. © 2015 the Nordic Societies of Public Health.

Braiding transformation, entanglement swapping, and Berry phase in entanglement space

Chen Jingling; Ge Molin; Xue Kang

2007-01-01

We show that braiding transformation is a natural approach to describe quantum entanglement by using the unitary braiding operators to realize entanglement swapping and generate the Greenberger-Horne-Zeilinger states as well as the linear cluster states. A Hamiltonian is constructed from the unitary R i,i+1 (θ,φ) matrix, where φ=ωt is time-dependent while θ is time-independent. This in turn allows us to investigate the Berry phase in the entanglement space

Public open space in housing estates plays an important role particularly in disaster mitigation. In some housing, there are indications of shape and use of space changes post-handover to local government. The aim of this study is to explore the relationship between public open space condition and management related to disaster mitigation in Tangerang housing estates. Multiple case study method is used to analyse of 2 housing cases. Aspects of access and boundaries were used to evaluate the cases. The results showed that gated community housing type should have more than 1 access to facilitate evacuation by considering the farthest unit to the housing gate. This is necessary to provide open spaces that are easily accessible from all units as the first evacuation site during and post disaster.

Civic activation, vulnerable subjects and public space: the case of the park of Rione Traiano in Naples

Full Text Available The woman, in every kind of human settlement, culture as well a time, plays a peculiar role in terms of active observation and multitasking actor of the urban form and their organization model. Studying urban phenomena through the filter of the gender interpretation and fostering a proactive participation of women in the process of urban planning could provide added value in terms of feasibility, effectiveness and efficiency. In this paper it was decided to dealing with this issue in the framework of public spaces through the construction of a case study centered on women-mothers and their contribution for interpreting and being proactive in a participatory process of urban regeneration. The expected result of this interactive process is twofold: developing a generalized methodology of interaction with communities for interpreting, in terms of space organization, the demand they express on the one hand as well as for dealing with specific context, with the involvement of activists and associations to define and share possible trajectories of transformation of public spaces, on the other hand. To pursue this goal we have chosen to deal with the specificities of a complex environment such as Naples and with a CEP district, the largest in Italy, whose construction was initiated in 1960: Rione Traiano. In this area has started a dialogue, with non-profit organizations operating in the area first and then with women in the community, in order to address the relationship between vulnerable people and public spaces, testing a methodology for interaction and civic activation finalized to collect, prioritize and translate into proposals instances as expressed by these subjects. The disciplinary horizon selected is the integration between established tools of community planning and project strategies typical of urban design.

"This is My Community": Reproducing and Resisting Boundaries of Exclusion in Contested Public Spaces.

Science.gov (United States)

Toolis, Erin E; Hammack, Phillip L

2015-12-01

The way that public space is structured has significant implications for identity, social interaction, and participation in society. For those experiencing homelessness, with no or limited private space, survival hinges on the accessibility and livability of public space. However, the increasing privatization of public space in the United States has contributed to the implementation of anti-homeless ordinances in cities, restricting sitting, standing, panhandling, and sleeping in public. This study analyzes data from interviews with housed and unhoused community members, text from a local policy document, and ethnographic observations to explore how boundaries between "insiders" and "outsiders" are drawn in public space and mediated through individual discourse. Our findings suggest that boundaries of exclusion are constructed through dominant narratives that portray the unhoused as a threat to safety and economic vitality, thus justifying the need for regulation and punishment through the criminalization of homelessness. Yet, informants also demonstrate resistance to this narrative by discussing how criminalization of homelessness perpetuates dehumanization, violence, and economic inequality. Policy implications for the regulation of public space are discussed.

Activating Public Space: How to Promote Physical Activity in Urban Environment

Science.gov (United States)

Kostrzewska, Małgorzata

2017-10-01

Physical activity is an essential component of a healthy lifestyle. The quality and equipment of urban public space plays an important role in promoting physical activity among people (residents, tourists). In order for recreation and sports activities to be undertaken willingly, in a safe and comprehensive manner, certain spatial conditions and requirements must be met. The distinctive feature of contemporary large cities is the disappearance of local, neighbourly relations, and the consequent loneliness, alienation, and atomization of the residents. Thus, the design of public spaces should be an expression of the values of social inclusion and integration. A properly designed urban space would encourage people to leave their homes and integrate, also by undertaking different forms of physical activities. This, in turn, can lead to raising the quality of the space, especially in the context of its “familiarization” and “domestication”. The aim of the research was to identify the architectural and urban features of the public spaces of contemporary cities that can contribute to the promotion of physical activity. The paper presents the research results and the case studies of such spatial solutions and examples of good practices, which invite residents to undertake different forms of physical activities in public spaces. The issue of the integrating, inclusionary, and social function of physical recreation and sport is discussed as well, and so are the possibilities of translating these values into physical characteristics of an urban space. The main conclusions are that taking into account the diverse needs of different social groups, participation in the design and construction process, aesthetic and interesting design, vicinity of the residence, open access for all age groups and the disabled would be the most important spatial determinants of a properly designed, physically activating public space.

On the form invariant volume transformation in phase space by focusing neutron guides: An analytic treatment

International Nuclear Information System (INIS)

Stüßer, N.; Hofmann, T.

2013-01-01

Tapered guides with supermirror coating are frequently used to focus neutron beams on specimens. The divergence distribution in the focused beam is of a great importance for the quality of neutron instrumentation. Using an analytic approach we derive the tapering which is needed to achieve a form invariant phase space transformation of a rectangular phase volume. In addition we consider the effect of beam attenuation by the finite reflectivity of supermirrors. -- Highlights: • Form invariant volume transformation in phase space. • Focusing modules for neutron beams. • Analytical approach. • Attenuation effects in linearly and nonlinearly tapered guides

Each day cities inhabitants are exposed to visual pollution. This work assess the environmental impact caused by visual pollution in public spaces, using as a case of study a mixed-use neighborhood in San Cristobal, the capital of Tachira state, Venezuela. Such assessment was made using a qualitative approach, where special emphasis was paid to the perception of these impacts by a purposive sample of users of this area. The compilation and analysis of information reveal the main visual pollutants existing in these public spaces where, in addition to outdoor advertising, overhead wires, rubbish, graffiti, vacant land, among others, cars and outdoor kiosks. Neighborhood users are sensitive to the presence of visual pollutants, which affects them physically and psychologically, as well as for the visual quality of their environment. Such signs were used to guide a qualitative appraisal of environmental impacts generated by these circumstances and to propose policies to mitigate them.

MUSICAL SPACE AS A WAY OF REFLECTING PUBLIC RELATIONS

Directory of Open Access Journals (Sweden)

MOZGOT SVETLANA

2017-12-01

Full Text Available The semantic universality of the space category and its relationship with the extra musical experience of the person provides composers an opportunity to model various forms of public relations in music. Being guided by E. Hall’s theory and the four models of communicative space identified by him – intimate, personal, social and public – we make an attempt to define the specific features of these spatial models in music. In this paper, the principles of E. Hall’s theory are for the first time projected on music. The research methods include hermeneutics, inter-disciplinary approach and musicological analysis. The research of the samples of instrumental music written by Scarlatti, Mozart, Beethoven, Chopin and Liszt showed the specific features of the intimate space model as the basic isolation of its structure, hierarchy and a special toponymy of the man’s inner world including the invariant steady presence of certain subjects and objects. The research of other spatial models in music shows prospects of conceiving the evolution of music as a special spatial form of reflecting the patterns of public consciousness and society arrangement.

Public Space, Public Waste, and the Right to the City.

2016-08-01

I draw on my experiences as an organizer with a waste-pickers collective, Kagad Kach Patra Kashtakari Panchayat in Pune, India, to reflect on the power dynamics in control of public space. The Pune Municipal Corporation (PMC), a public body, has used public resources to facilitate and enable accumulation by private companies, who have not been able to produce what they had committed to in the processing of waste. The waste pickers, in alliance with affected village-based land agitation committees, have mobilized against the dumping that is ruining their way of life, environments, and health, and are fighting for their own integration into waste value chains. The article uses the frame of David Harvey's(1) "right to the city"; a key part of the mobilizing work with waste pickers has been Freirean conscientization methods to spread awareness of the economic importance, to the city and to the planet, of waste recycling. © The Author(s) 2016.

2014-08-01

Full Text Available Continuous changes in the external environment deriving from legislative, economic and technological factors, puts pressure not only to corporate organizations, but also to public service organizations. These changes have increased pressure on service delivery and calls for accountability in public service organizations. With this increased pressure comes the need for public service organizations to discover how to most effectively enhance their organizational performance. Two of the most effective ways to improve performance are through the organizational leadership and culture. Although many studies were conducted on transformational leadership and organizational culture, there is still a need to investigate the link between these constructs in public service organizations. Hence the objective of this study was to explore the relationship between transformational leadership and organizational culture for service delivery practices. The Leadership Practice Inventory (LPI and Organizational Culture Inventory (OCI were administered to a random sample size of N=238, from a population of 4350 employees working within the public service organization. Descriptive statistics and Pearson’s correlation were conducted to analyse the data. The results of this study indicated a significant positive relationship between transformational leadership and the constructive dimension of organizational culture within a public service organization. In terms of contributions and practical implications, insight gained from the findings may be used in proposing leadership and organizational development interventions and future research

Alternative for the recovery of public space through green infrastructures in Tunja, Colombia

Directory of Open Access Journals (Sweden)

Laura Estefanía Quintero González

2017-12-01

Full Text Available The current global demographic explosion has impacted in an excessive growth of cities, with urban areas invading key environmental places and with it, reducing the possibility of keeping good public spaces. Tunja is one of the growing cities of Colombia and its central zone needs an alternative of recovery and generation of public green spaces to avoid densification. The research proposes: firstly, to determine the availability of existing public space in the urban area of Tunja through a characterization and availability diagnosis; and, secondly, to formulate specific types of green infrastructure. By considering the regular state conditions of the existing public space network and the inequality in the spatial connectivity of the places within the system, a proposal of types of vegetated infrastructures is given to improve both existing and potentially places.

Second order oscillations of a Vlasov-Poisson plasma in the Fourier transformed space

International Nuclear Information System (INIS)

Sedlacek, Z.; Nocera, L.

1991-05-01

The Vlasov-Poisson system of equations in the Fourier-transformed velocity space is studied. At first some results of the linear theory are reformulated: in the new representation the Van Kampen eigenmodes and their adjoint are found to be ordinary functions with convenient piece-wise continuity properties. A transparent derivation is given of the free-streaming temporal echo in terms of the kinematics of wave packets in the Fourier-transformed velocity space. This analysis is further extended to include Coulomb interactions which allows to establish a connection between the echo theory, the second order oscillations of Best and the phenomenon of linear sidebands. The calculation of the time evolution of the global second order electric field is performed in detail in the case of a Maxwellian equilibrium distribution function. It is concluded that the phenomenon of linear sidebands may be properly explained in terms of the intrinsic features of the equilibrium distribution function. (author) 5 figs., 32 refs

Public evaluation of open space in Illinois: citizen support for natural area acquisition.

Backlund, Erik A; Stewart, William P; McDonald, Cary; Miller, Craig

2004-11-01

Numerous studies have indicated a broad-based support for open space preservation and protection. Research also has characterized the public values and rationale that underlie the widespread support for open space. In recognition of the widespread public support for open space, various levels of government have implemented programs to provide public access to open space. There are many different types of open space, ranging from golf courses, ball parks, wildlife areas, and prairies, to name a few. This paper addresses questions related to the types of open space that should be prioritized by planners and natural resource managers. The results of this study are based on a stratified random sample of 5000 households in Illinois that were sent a questionnaire related to their support for various types of open space. Through a comparatively simple action grid analysis, the open space types that should be prioritized for public access include forest areas, stream corridors, wildlife habitat, and lakes/ponds. These were the open space types rated of the highest importance, yet were also the open space types rated the lowest in respondent satisfaction. This kind of analysis does not require the technical expertise of other options for land-use prioritizations (e.g., conjoint analysis, contingent valuation), yet provides important policy directives for planners. Although open space funds often allow for purchase of developed sites such as golf courses, ball parks, and community parks, this study indicates that undeveloped (or nature-based) open space lands are most needed in Illinois.

map public participation - consultation, consensus shaping processes and safe space. In contrast to consensus shaping processes, in the safe space approach there is no intention to develop solutions together between the implementer and other stakeholders. In comparison with the ladder, the basic approaches offer advantages for the mapping of public participation processes: If you strive for consensus or ''only'' clarity and awareness is a crucial question to be answered before a process is launched as it determines which stakeholders can join and which goals are feasible to reach. It is easier to use in assigning properties to a process, as it more straight-forward to understand if a process is consensus shaping or a safe space than where it is on the ladder. It clarifies better the links between the participation processes and the actual political and/or legal decision-making process. A consensus shaping process should produce real advice (or even decisions) but a safe space is limited to improving the decision making base with enhanced clarity.

2002-01-01

In April 2001 the German Aerospace Society DGLR e.V. in cooperation with the Technical University of Darmstadt, Germany initiated an interdisciplinary students contest, under the patronage of Mr. Joerg Feustel-Buechl, the Director of Manned Spaceflight and Microgravity, European Space Agency (ESA), for the summer term 2001. It was directed to graduated architecture students, who had to conceive and design a space-hotel with specific technical, economical and social requirements. The to be developed Space Hotel for a low earth orbit has to accommodate 220 guests. It was of utmost importance that this contest becomes an integral part of the student's tuition and that professors of the different academic and industrial institutions supported the project idea. During the summer term 2001 about fifty students occupied themselves with the topic, "design of an innovative space-hotel". The overall challenge was to create rooms used under microgravity environment, which means to overcome existing definitions and to find a new definition of living space. Because none of the students were able to experience such a room under microgravity they were forced to use the power of their imagination capability. The students attended moreover a number of lectures on different technical subjects focusing on space and went on several space-related excursions. Having specialists, as volunteers, in the field of space in charge meant that it could be ensured that the designs reflected a certain possibility of being able to be realized. Within the summer term seventeen major designs developed from the conceptual status to high sophisticated concepts and later on also to respective models. A competition combined with a public exhibition, that took place within the Annual German Aeronautics and Astronautics Congress, and intense media relations finalized this project. The project idea of "Early Bird - Visions of a Space Hotel" which was developed within six month is a remarkable example, how

Patterns of Intergroup Contact in Public Spaces: Micro-Ecology of Segregation in Australian Communities

Directory of Open Access Journals (Sweden)

Naomi Priest

2014-01-01

Full Text Available The use of public spaces can promote social cohesion and facilitate interpersonal interactions within the community. However, the ways racial and ethnic groups interact in public spaces can also reflect and influence informal segregation in the wider community. The present study aimed to examine patterns of intergroup contact within public spaces in Victoria, Australia through short-term observation in four localities. Data were collected on within-group, intergroup and absence of contact for people from minority and majority groups. A total of 974 contacts were observed. Findings indicate that in the observed public spaces, people from visible minority groups tended to have no contact with others or to interact with people from other ethnic/racial groups. In contrast, those from the majority group tended to interact predominately with other majority group members. This suggests that majority group members are more likely to ‘self-segregate’ in public spaces than those from minority groups.

The Bargmann transform and canonical transformations

International Nuclear Information System (INIS)

Villegas-Blas, Carlos

2002-01-01

This paper concerns a relationship between the kernel of the Bargmann transform and the corresponding canonical transformation. We study this fact for a Bargmann transform introduced by Thomas and Wassell [J. Math. Phys. 36, 5480-5505 (1995)]--when the configuration space is the two-sphere S 2 and for a Bargmann transform that we introduce for the three-sphere S 3 . It is shown that the kernel of the Bargmann transform is a power series in a function which is a generating function of the corresponding canonical transformation (a classical analog of the Bargmann transform). We show in each case that our canonical transformation is a composition of two other canonical transformations involving the complex null quadric in C 3 or C 4 . We also describe quantizations of those two other canonical transformations by dealing with spaces of holomorphic functions on the aforementioned null quadrics. Some of these quantizations have been studied by Bargmann and Todorov [J. Math. Phys. 18, 1141-1148 (1977)] and the other quantizations are related to the work of Guillemin [Integ. Eq. Operator Theory 7, 145-205 (1984)]. Since suitable infinite linear combinations of powers of the generating functions are coherent states for L 2 (S 2 ) or L 2 (S 3 ), we show finally that the studied Bargmann transforms are actually coherent states transforms

Nonetheless, to date, there has been limited research on everyday activities of urban older adults in public open spaces. The present study examined the activities of older adults in public open spaces in Israel with a specific focus on age and gender as potential variables of relevance. Using still photography, we systematically photographed four sessions in two different public outdoor settings attended by older Israelis. Still photographs were converted to narrative descriptions, and then coded, quantified, and compared using descriptive statistics. The majority (311, 97%) of older adults arrived alone to the public setting. Of these, 44% formed a social group of two or more people, whereas the remaining older adults stayed alone. When social interactions occurred, they were primarily gender homogenous (69%); women were more likely to integrate in spontaneous social conversations and men were more likely to participate in common games. Our findings call attention to the important role played by the outdoor environment as a venue for social activities among older adults. The findings further stress the high levels of aloneness experienced by older adults, which do not seem to be alleviated by the mere attendance of public spaces. © The Author 2017.

Ethical and legal analyses of policy prohibiting tobacco smoking in enclosed public spaces.

Science.gov (United States)

Oriola, Taiwo A

2009-01-01

A spate of legislations prohibiting cigarette smoking in enclosed public spaces, mainly on grounds of public health protection, recently swept across cities around the world. This is in tandem with a raft of increasingly restrictive national laws that emerged on the back of the ratification of the WHO Framework for Tobacco Control by more than one 168 countries in 2005. The central debate on the increasingly restrictive tobacco laws revolves on the extent to which public health interests justification should ground political intervention in a private right as basic as tobacco smoking, which interestingly is often lumped in the food and beverage category. The pertinent legal and ethical questions therefore are the following: Is or should there be a general unrestricted right to tobacco smoking? If there were such a right, should public health or ethical considerations trump private right to smoke in enclosed public spaces? And if public health interests were so paramount, should they go farther and ground tobacco smoking proscription in all private and public spheres? Using ethical principles and rights-based arguments, the paper critically examines the legal and ethical ramifications of public health justification for tobacco smoking proscription in enclosed public spaces.

In this paper it is shown that the generalization of the Yang-Mills equations in Minkowsky space to the case of the biquaternions over dual and double numbers enables one to define the corresponding representations of the Galilei and SO(4) groups in a rather natural way. it makes construction of the non-Abelian field equations in Euclidean and Galilei-Newton spaces possible and proves their invariance under generalized dual transformations by use of the analogy with the Abelian gauge

Migrants' Remittances end the Transformation of Local Spaces: The Case of Financial Markets in Mexico

Directory of Open Access Journals (Sweden)

Christian Ambrosius

2014-06-01

Remittances, the money sent by migrants to their families back home, are situated outside ‘traditional’ categories of space in several ways. Not only do these smallscale financial transactions span the transnational space beyond the nation-state; they also move largely outside the institutional spaces of the formal banking sector. Taking the case of financial markets in Mexico and building on recent empirical findings on the impact of migrants’ remittances on the financial sector of the receiving countries, this article explores how remittances may lead to a transformation of local spaces by reducing some of the market failures that prevail, especially in rural financial markets.

Misting-cooling systems have been used in outdoor spaces mainly for aesthetic purposes, and punctual cooling achievement. However, they can be highly effective in outdoor spaces’ bioclimatic comfort, in terms of microclimatic control, as an evaporative cooling system. Recent concerns in increasing bioclimatic standards in public outdoor spaces, along with more sustainable practices, gave origin to reasoning where plastic principles are combined with the study of cooling efficacy, in order to ...

2016-01-01

The change toward a public value management (PVM) paradigm in the public sector has challenged urban green space managers to rethink how they define and assess their services. In the Nordic countries, the challenge has resulted in the development of the Nordic Green Space Award (NSGA), as a new...... shared standard. This article reviews the NGSA scheme and its development. The development of the scheme embodies a methodology for how the question of ‘what makes for a good urban green space' collectively can be addressed within a particular regional context. The resulting scheme relies on ‘structure...... and general aspects', 'functionality and experience', and ‘management and organisation', as three principal themes and provides an easily manageable, unified and affordable approach to assessment of a variety of urban green spaces. Conceptually, the scheme resembles other comparable assessment schemes...

Micropolitics of Public Space: On the Contested Limits of Citizenship as a Locational Practice

Directory of Open Access Journals (Sweden)

Andrés Di Masso

2015-10-01

Full Text Available This article provides a social-psychological account of how public space dynamics may be consequential for the daily construction of citizenship. The article is organised around three interrelated ideas that are illustrated by a case study. First, it is argued that certain social-psychological processes that are typically involved in the construction of citizenship can be re-conceptualised as place-based processes that are located in public space. This interest in the ‘locational’ construction of citizenship implies focusing on membership, belonging, status, rights, entitlements and recognition as emplaced practices rather than as dislocated entities. The second idea relates to the troubled nature of citizenship as a place-related psychological category whose boundaries are hotly contested whenever disputes about controversial behaviour in public spaces surface. Accordingly, ‘the citizen’ is constantly re-shaped as everyday place-discourses and territorial practices in the public domain unfold in problematic ways. Finally, it is argued that such ‘locational’ constructions and enactments of citizenship in public space are usually framed by broader ideological dilemmas that are relevant to the maintenance and change of a given socio-political order. The ultimate purpose of the article is to demonstrate the potential for public space to become a possible site for grounding a social psychology of citizenship.

2004-01-01

Full Text Available The analytic self-map of the unit disk D, φ is said to induce a composition operator Cφ from the Banach space X to the Banach space Y if Cφ(f=f∘φ∈Y for all f∈X. For z∈D and α>0, the families of weighted Cauchy transforms Fα are defined by f(z=∫TKxα(zdμ(x, where μ(x is complex Borel measure, x belongs to the unit circle T, and the kernel Kx(z=(1−x¯z−1. In this paper, we will explore the relationship between the compactness of the composition operator Cφ acting on Fα and the complex Borel measures μ(x.

On public space design for Chinese urban residential area based on integrated architectural physics environment evaluation

2017-04-01

The residential public space is an important part in designing the ecological residence, and a proper physics environment of public space is of greater significance to urban residence in China. Actually, the measure to apply computer aided design software into residential design can effectively avoid an inconformity of design intent with actual using condition, and a negative impact on users due to bad architectural physics environment of buildings, etc. The paper largely adopts a design method of analyzing architectural physics environment of residential public space. By analyzing and evaluating various physics environments, a suitability assessment is obtained for residential public space, thereby guiding the space design.

[An assessment of fiscal space for public health in Peru].

Matus-López, Mauricio; Toledo, Lorena Prieto; Pedraza, Camilo Cid

2016-08-01

Objective To assess the fiscal space for public health in Peru so as to attain the goal of raising health spending to 6% of gross domestic product, as agreed upon by member countries of the Pan American Health Organization in 2014. Methods The main sources of fiscal space were identified by means of a thorough literature review. Technical feasibility was determined from statistics and national and international surveys and by reviewing various documents and official reports. Political feasibility was ascertained by studying policy guidelines. Results The sources showing the greatest technical and political feasibility are economic growth, a broadening of the personal income tax base, and an increase in tobacco-specific taxes. Decreasing informality in the job market and increasing contributory coverage are considered to be less politically feasible, but there is ample technical space for these measures. Conclusions There is enough fiscal space to allow for an increase in public health spending. Nevertheless, the 6% target will be reached only if the timeline is extended, tax revenues are increased, and informality in the job market is reduced.

Sustainability is an overarching sense of responsibility towards the future. On a city-wide level, urban sustainability incorporates a wide body of changes especially as they relate to the built environment, all of which intended at creating a livable place. This paper discusses existing public spaces in view of their achievement against a set of criteria for the built environment. The paper introduces performance design criteria for the tropical built environment. The key findings indicate that long-term strategies, guidance and directions for the city and region can achieve development which corresponds to local climate, synergies and provide a higher proportion of public spaces that offer something for everyone.

Extended system of space-time coordinates and generalized translation group of transformations

International Nuclear Information System (INIS)

Yamaleev, R.M.

1980-01-01

A method of extending space-time is considered. In the nonrelativistic case extending goes by joining a scalar to the 3-dimensional radius-vector, completing this to a quaternion. The interpretation of scalar obtained as a parameter of scale transfornation of the generalized translation of group of transformations is given. Some basic expressions of nonrelativistic classical mechanics in the quaternion representation are given. In the relativistic case space-time is constructed from two quaternions: the first one consists of a pair scalar-3-dimensional radius-vector; the second one, of a pair-time-scalar-3-dimensional time-vector. Time and space coordinates, enter into the expression with the opposite signature. The introduction of a time-vector as well as of a new scalar is stipulated by the requirement of the principle of conforming quantum mechanics of the 1/2 spin to classical mechanics [ru

The Public Space of “Jogja Fashion Week Carnival” and Cosplay Clothing in Yogyakarta

Directory of Open Access Journals (Sweden)

Deni Setiawan

2015-01-01

Full Text Available The concept of an ideal public space does not just focus on the interests of a particular group or community, but rather focus on the space of social activities that represent each audience or spectator in that society. Arts and cultural activities are part of it; although the concept of public space is still abstract to represent every social individual. However, the presence of public space has created a mediation space for all forms of communication. Mediation space is considered as a crucial feature, not only as a promotional sphere but also as a place to exchange and communicate all forms of ideology, art, and culture. Art activities such as Jogja Fashion Week Carnival and Cosplay clothing performance in public spaces provide opportunities for communities or individuals, to make this activity as a public performance and part of public art. Public art tends to be creative, free, and sometimes not accompanied by a theoretical perspective, as other arts are. Art activities in public spaces which are part of the social and cultural activities are essentially standing on the ideology that have been set up for a particular interest. The interest is disseminated using mass media and advertisment. Audience or public art connoisseur in public spaces should be more intelligent and critical to accept all kinds of art activities and performances. Therefore the performance will have a balanced communication.AbstrakKonsep ruang publik yang ideal tidak saja berbicara kepentingan golongan atau komunitas tertentu, tetapi lebih fokus pada wadah aktivitas sosial yang mewakili setiap pendatang atau penonton.

A state-space Bayesian framework for estimating biogeochemical transformations using time-lapse geophysical data

Energy Technology Data Exchange (ETDEWEB)

Chen, J.; Hubbard, S.; Williams, K.; Pride, S.; Li, L.; Steefel, C.; Slater, L.

2009-04-15

We develop a state-space Bayesian framework to combine time-lapse geophysical data with other types of information for quantitative estimation of biogeochemical parameters during bioremediation. We consider characteristics of end-products of biogeochemical transformations as state vectors, which evolve under constraints of local environments through evolution equations, and consider time-lapse geophysical data as available observations, which could be linked to the state vectors through petrophysical models. We estimate the state vectors and their associated unknown parameters over time using Markov chain Monte Carlo sampling methods. To demonstrate the use of the state-space approach, we apply it to complex resistivity data collected during laboratory column biostimulation experiments that were poised to precipitate iron and zinc sulfides during sulfate reduction. We develop a petrophysical model based on sphere-shaped cells to link the sulfide precipitate properties to the time-lapse geophysical attributes and estimate volume fraction of the sulfide precipitates, fraction of the dispersed, sulfide-encrusted cells, mean radius of the aggregated clusters, and permeability over the course of the experiments. Results of the case study suggest that the developed state-space approach permits the use of geophysical datasets for providing quantitative estimates of end-product characteristics and hydrological feedbacks associated with biogeochemical transformations. Although tested here on laboratory column experiment datasets, the developed framework provides the foundation needed for quantitative field-scale estimation of biogeochemical parameters over space and time using direct, but often sparse wellbore data with indirect, but more spatially extensive geophysical datasets.

Twistorial formulation of a particle of arbitrary spin has been constructed. The twistor formulation is deduced from a space-time formulation of the spinning particle by introducing pure gauge Lorentz harmonics in this system. Canonical transformations and gauge fixing conditions, excluding space-time variables, produce the fundamental conditions of twistor transform relating the space-time formulation and twistor one. Integral transformations, relating massive twistor fields with usual space-time fields, have been constructed

Child-friendly integrated public spaces (RPTRA): Uses and sense of attachment

Science.gov (United States)

Prakoso, S.; Dewi, J.

2018-03-01

The Jakarta City Provincial Government undertook an extensive citywide initiative to build small public urban green spaces, called child-friendly integrated public spaces (RPTRA). Studies on how citizens, including children, use RPTRA was limited, and questions regarding whether children had become attached to the RPTRA as one of their favorite places remain unanswered. This paper presents a preliminary study on ten RPTRA located in Jakarta. We examine how children and citizens use the spaces, based on data from respondents who completed on-site questionnaires during the course of their visit to the RPTRA. We also measure the degree of children’s sense of attachment to RPTRA. The results show that children primarily use RPTRA for playing and learning. Women and girls use RPTRA the most, and elderly citizens use it the least. The results of the study also demonstrate that children had developed a sense of attachment to RPTRA and it had become one of their favorite places. This study may have implications on the existence of small public urban green spaces like RPTRA as valuable assets in the everyday lives of children and citizens. It proposes that RPTRA should be taken into account for future planning of densely populated urban areas.

This article joins these two concepts into one scope and surveys the identity of both. In ideal (utopian? traditional context between private and public music experience (life, the context shows ideal vitality and consistence, while in an 'irregular' context these two concepts begin to distance themselves, opening space for marginality or so called 'errors'.

'You're there because you are unprofessional': patient and public involvement as liminal knowledge spaces.

Science.gov (United States)

Maguire, Kath; Britten, Nicky

2018-03-01

Patient and public involvement in health research and care has been repeatedly theorised using the metaphor of spaces, knowledge spaces and participatory citizenship spaces. Drawing on data from a three year qualitative study of people involved in health research with organisations across England, this article explores where these spaces fit in a wider social, political and historical landscape. It outlines a theme recurring frequently in the study data: a unified public/patient/service-user perspective in opposition to a professional/clinical/academic view. This is discussed in relation to Habermas's division between the lifeworld and system. Patient and public involvement is mapped as spaces between these spheres, therefore between the social norms pertaining to them. In this way, involvement spaces are seen as liminal, in-between or threshold spaces; this concept provides us with new insights on both the opportunities and the conflicts that are integral in the ambiguous, complex interactions which take place in these spaces. © 2017 Foundation for the Sociology of Health & Illness.

Access to public open space is important to increase leisure-time walking (LTW) in high-income countries, but there is little evidence in middle-income countries. We conducted a cross-sectional analysis to examine the relationship between LTW and the presence of different public open spaces (parks, bike paths, and squares) and the mix of these recreational destinations near the homes of adults participating in the Sao Paulo Health Survey ( n = 3145). LTW was evaluated by a questionnaire. We delineated buffers (500, 1000, and 1500 m) from the geographic coordinates of the adults' residential addresses using a geographic information system. We used multilevel logistic regression taking account of clustering by census tracts and households, and with adjustment for social, demographics, and health characteristics. The main results showed that the presence of at least two recreational destinations within a 500-m buffer of participants' homes were associated with an increased odds of LTW compared with no destinations present (OR = 1.65; 95% CI 1.09-2.55). No associations were found for destinations further away. These results support actions outlined in the new urban plan for Sao Paulo city and could be used to highlight the importance access to a mix of public open spaces to promote physical activity in megacities of middle-income countries.

It is shown that the conformal group of compactified Minkowski space is isomorphic to a group of rays of semilinear transformations of twistor space. The action of the conformal group on twistor space is given by an explicit realisation of this isomorphism. In this way we determine the transformation of twistor space under space inversion and time inversion. (orig.)

Public spaces in a planned housing is a place of social interaction for every visitor of public space. The research on public space image uses four public spaces that meet the criteria of public space such as pedestrian sidewalks, public park, water front and worship place. Research on the perception of public space is interesting to investigate because housing development is part of the forming of a society that should design with proper architectural considerations. The purpose of this research is to know the image of public space on the planned housing in Medan City based on the mapping of environmental and behavior cognition and to know the difference between the image that happened to four group respondent. The research method of architecture used in this research is a descriptive qualitative method with case study approach (most similar case). Analysis of data used using mental maps and questionnaires. Then the image of public space is formed based on the elements of public space, wayfinding, route choice, and movement. The image difference that occurs to the housing residents and architecture students, design and planning are outstanding, visitors to the public housing space is good, people who have never visited the public space is inadequate.

For two decades the Nuclear and Energy Research Institute (IPEN) has been developing activities for popularization of its R and D activities in the nuclear field. Some of the initiatives already undertaken by IPEN are lectures at schools, guided visits to IPEN facilities, printed informative material, FAQ page in the Web, and displays in annual meetings and technology fairs highlighting its achievements. In order to consolidate these initiatives, IPEN is planning to have a permanent Space of Nuclear Technology (SNT), aiming at introducing students, teachers and the general public to the current applications of nuclear technology in medicine, industry, research, electric power generation, etc. It is intended as an open room to the public and will have a permanent exhibit with historical, scientific, technical and cultural developments of nuclear technology and will also feature temporary exhibitions about specific themes. The space will display scientific material in different forms to allow conducting experiments to demonstrate some of the concepts associated with the properties of nuclear energy, hands-on programs and activities that can be customized to the students' grade level and curriculum.

Three dimensional canonical transformations

International Nuclear Information System (INIS)

Tegmen, A.

2010-01-01

A generic construction of canonical transformations is given in three-dimensional phase spaces on which Nambu bracket is imposed. First, the canonical transformations are defined as based on cannonade transformations. Second, it is shown that determination of the generating functions and the transformation itself for given generating function is possible by solving correspondent Pfaffian differential equations. Generating functions of type are introduced and all of them are listed. Infinitesimal canonical transformations are also discussed as the complementary subject. Finally, it is shown that decomposition of canonical transformations is also possible in three-dimensional phase spaces as in the usual two-dimensional ones.

Design of Urban Public Spaces: Intent vs. Reality

Directory of Open Access Journals (Sweden)

Mikkel Hjort

2018-04-01

Full Text Available This study investigated how two public spaces for sport and recreation were utilized by different user groups, and how this aligned with the initial design objectives for these spaces. Two newly built urban spaces situated in Copenhagen, Denmark, provided the context for this investigation. The System for Observing Play and Recreation in Communities (SOPARC was used to examine the physical activity of users in these two urban spaces. The architects responsible for designing each space were interviewed to ascertain the intended target group of each space and to unravel the reasons behind the design decisions. The SOPARC observations revealed that males were more vigorously active than females when using the recreation facilities, and the observed users did not align with the intended target groups. The interviews suggested that design decisions were based on minimal interdisciplinary knowledge, and that expert knowledge was chosen randomly. These findings point to a systematic lack of evidence-based practice when designing sport and recreational facilities. This article has implications for landscape architects and urban planners; a new method must be developed to embed interdisciplinary knowledge in the planning process of future sport and recreation projects. This must be done in a systematic way to make the design process transparent.

A suite of informal interactive public engagement initiatives was created, to promote the importance of Space exploration, to ignite curiosity and discover new and engaging platforms for science in the Arts & in STEM Education, and to increase awareness of careers in Ireland's Space science industries. These included: (1)'To Space'- A live multimedia theatre performance aimed at the general public & young adult, (2) an adaptation of 'To Space' for 13- 17 year old students entitled 'ToSpace for School leavers' and (3) 'My Place in Space', created for families. Blending humour, warmth and humanity and positioning science within story is a highly effective public engagement tool in igniting curiosity across many audience types. The nurturing and investment of artists working within these new cross-disciplinary relationships should be encouraged and supported to further broaden and develop new methodology in public engagement of the planetary sciences.

Full Text Available The city that grows unplanned usually arises because of the conurbations of a culture, such as Agora in Greek and Forum in Roman. The “unplanned” city grows in strategic places, such as around the harbor, business places, worship places, or other activity centers. The city growth due to cultural centers is usually characterized by the growth of services as the economic support of the city activities. The service center develops a community center in the form of public facilities, such as public spaces and public buildings. Western understanding about this kind of design is oriented to functional vision illustrated from several illustrations of history that developed in the world of architecture. Understanding of cosmology in typology and morphology that affect the built environment, especially the face of a city, can be described by reviewing some of the phenomena that have been developed in connection with cosmological concept that affects the embryo of market formation, ie public open spaces which became the center of city residents to the commercial, political, recreational activities, and others resulting from the interaction of community activities. 

Learning Landscapes: Playing the Way to Learning and Engagement in Public Spaces

Directory of Open Access Journals (Sweden)

Brenna Hassinger-Das

2018-05-01

Full Text Available Children from under-resourced communities regularly enter formal schooling lagging behind their peers. These deficits in areas such as language development, reading readiness, and even in the kind of spatial skills that predict later mathematical knowledge, may persist throughout their lifespan. To address such gaps, policymakers have focused largely on schooling as the great equalizer. Yet, children only spend 20% of their waking hours in school. How can developmental scientists and educators address this “other 80%” for the benefit of children’s development? One answer is the Learning Landscapes initiative, which involves crafting carefully planned play experiences that focus on learning outcomes, particularly for children and families from under-resourced communities. Playful learning, a broad pedagogical approach featuring child-directed play methods, provides a unique way to foster learning and engagement organically within the built environment. Learning Landscapes already incorporates several well-documented projects. The Ultimate Block Party brought over 50,000 people to Central Park to engage in playful learning activities. Supermarkets became hotspots for caregiver-child interaction by simply adding prompts for caregiver-child interaction through signage in everyday “trapped” experiences. Urban Thinkscape transformed a bus stop and adjacent lot into a hub for playful learning while families were waiting for public transportation. Finally, Parkopolis is a life-size human board game that fosters STEM and reasoning skills in public spaces. This paper reflects on data from these projects while reflecting on lessons learned and future directions.

Learning strategies of public health nursing students: conquering operational space.

Hjälmhult, Esther

2009-11-01

To develop understanding of how public health nursing students learn in clinical practice and explore the main concern for the students and how they acted to resolve this main concern. How professionals perform their work directly affects individuals, but knowledge is lacking in understanding how learning is connected to clinical practice in public health nursing and in other professions. Grounded theory. Grounded theory was used in gathering and analysing data from 55 interviews and 108 weekly reports. The participants were 21 registered nurses who were public health nursing students. The grounded theory of conquering operational space explains how the students work to resolve their main concern. A social process with three identified phases, positioning, involving and integrating, was generated from analysing the data. Their subcategories and dimensions are related to the student role, relations with a supervisor, student activity and the consequences of each phase. Public health nursing students had to work towards gaining independence, often working against 'the system' and managing the tension by taking a risk. Many of them lost, changed and expanded their professional identity during practical placements. Public health nursing students' learning processes in clinical training are complex and dynamic and the theory of 'Conquering operational space' can assist supervisors in further developing their role in relation to guiding students in practice. Relationships are one key to opening or closing access to situations of learning and directly affect the students' achievement of mastering. The findings are pertinent to supervisors and educators as they prepare students for practice. Good relationships are elementary and supervisors can support students in conquering the field by letting students obtain operational space and gain independence. This may create a dialectical process that drives learning forward.

The rapid development of information technology has had a great impact on the understanding of urban environment, which brings different spatially psychological experience. Information and image transmission has been full with the streets, both the physical space and virtual space have been unprecedentedly blended together through pictures, images, electronic media and other tools, which also stimulates people’s vision and psychology and gives birth to a more complex form of urban space. Under the dual role of spatial mediumlization and media spatialization, the psychological cognitive pattern of urban public space context is changing.

Action Research as a Space for Transforming Learning Cultures

2015-12-01

Full Text Available The article presents a three-year educational action research project on autonomous and reflective learning. Students and teachers, being actively engaged in many learning practices, were both participating in process(es of developing educational and research community. These interrelated processes framed a dynamic space for constructing and reconstructing the participants’ learning cultures. Thanks to linking educational and research aspects of students’ activity and to interpenetration of practice and reflection, action research generates particular conditions for learning cultures’ transformation, from “traditional” toward “new” ones, based on reflectivity, authenticity and empowerment. The dynamism of learning cultures was connected to various and conscious and reflective types of educational participation, which affected autonomy of studying (in its numerous dimensions and types, being in turn a constitutive element of participants’ learning cultures.

Keeping space public : Times Square (New York and the Senegalese peddlers

Stéphane Tonnelat

2007-03-01

Full Text Available This paper explores the public nature of Times Square's physical and represented (TV, internet, press spaces through an analysis of the techniques used by Senegalese male peddlers to sell souvenirs to the visiting tourists. Whereas a number of scholars denounce the Disneyfication of Times Square, in other words its privatization, the observation of the peddlers shows that there is an almost self-regulated social order of the flow escaping the control of the pseudo-public institution in charge of Times Square, the Business Improvement District. On the other hand, the difficulties encountered by the vendors also reveal another Times square, less public, constituted by the accumulation of images captured by the finance and media companies settled in the office towers. This "clean and safe" pseudo-private space (Mitchell and Staeheli 2006 cannot tolerate the presence of the vendors, thus pushing them to the blind spots of the site. It nevertheless relies on the dynamics of the flow, thus preserving a place for the vendors and the public nature of the physical space of Times Square. But how long can this compromise work?

We examined associations between specific public open space (POS) attributes and recreational walking to local POS. Between October 2004 and December 2006, 1465 adults of the RESIDential Environments Project, conducted in Perth, Australia, reported whether they walk to a POS for recreation. For each participant, we identified all open spaces larger than 0.8 hectares within 1.6 kilometers from home. On the basis of field audit data, we created 3 scores (presence, count, size-weighted presence) for 19 specific open space attributes. With logistic regression analyses, we found that walking to a POS was associated with the presence of gardens, grassed areas, walking paths, water features, wildlife, amenities, dog-related facilities, and off-leash areas for dogs. It was also associated with the highest number of these attributes in a single open space, but not with the total number of attributes in all POSs within 1.6 kilometers of home. Building 1 high-quality local park may be more effective in promoting recreational walking than is providing many average-quality parks.

An image hiding method based on cascaded iterative Fourier transform and public-key encryption algorithm

Science.gov (United States)

Zhang, B.; Sang, Jun; Alam, Mohammad S.

2013-03-01

An image hiding method based on cascaded iterative Fourier transform and public-key encryption algorithm was proposed. Firstly, the original secret image was encrypted into two phase-only masks M1 and M2 via cascaded iterative Fourier transform (CIFT) algorithm. Then, the public-key encryption algorithm RSA was adopted to encrypt M2 into M2' . Finally, a host image was enlarged by extending one pixel into 2×2 pixels and each element in M1 and M2' was multiplied with a superimposition coefficient and added to or subtracted from two different elements in the 2×2 pixels of the enlarged host image. To recover the secret image from the stego-image, the two masks were extracted from the stego-image without the original host image. By applying public-key encryption algorithm, the key distribution was facilitated, and also compared with the image hiding method based on optical interference, the proposed method may reach higher robustness by employing the characteristics of the CIFT algorithm. Computer simulations show that this method has good robustness against image processing.

Full Text Available Access to public open space is important to increase leisure-time walking (LTW in high-income countries, but there is little evidence in middle-income countries. We conducted a cross-sectional analysis to examine the relationship between LTW and the presence of different public open spaces (parks, bike paths, and squares and the mix of these recreational destinations near the homes of adults participating in the Sao Paulo Health Survey (n = 3145. LTW was evaluated by a questionnaire. We delineated buffers (500, 1000, and 1500 m from the geographic coordinates of the adults’ residential addresses using a geographic information system. We used multilevel logistic regression taking account of clustering by census tracts and households, and with adjustment for social, demographics, and health characteristics. The main results showed that the presence of at least two recreational destinations within a 500-m buffer of participants’ homes were associated with an increased odds of LTW compared with no destinations present (OR = 1.65; 95% CI 1.09–2.55. No associations were found for destinations further away. These results support actions outlined in the new urban plan for Sao Paulo city and could be used to highlight the importance access to a mix of public open spaces to promote physical activity in megacities of middle-income countries.

The space-math link in preschool boys and girls: Importance of mental transformation, targeting accuracy, and spatial anxiety.

Science.gov (United States)

Wong, Wang I

2017-06-01

Spatial abilities are pertinent to mathematical competence, but evidence of the space-math link has largely been confined to older samples and intrinsic spatial abilities (e.g., mental transformation). The roles of gender and affective factors are also unclear. This study examined the correlations between counting ability, mental transformation, and targeting accuracy in 182 Hong Kong preschoolers, and whether these relationships were weaker at higher spatial anxiety levels. Both spatial abilities related with counting similarly for boys and girls. Targeting accuracy also mediated the male advantage in counting. Interestingly, spatial anxiety moderated the space-math links, but differently for boys and girls. For boys, spatial abilities were irrelevant to counting at high anxiety levels; for girls, the role of anxiety on the space-math link is less clear. Results extend the evidence base of the space-math link to include an extrinsic spatial ability (targeting accuracy) and have implications for intervention programmes. Statement of contribution What is already known on this subject? Much evidence of a space-math link in adolescent and adult samples and for intrinsic spatial abilities. What does this study add? Extended the space-math link to include both intrinsic and extrinsic spatial abilities in a preschool sample. Showed how spatial anxiety moderated the space-math link differently for boys and girls. © 2016 The British Psychological Society.

Public Spaces as the Reflection of Society and its Culture

Siláči, Ivan; Vitková, L.'ubica

2017-10-01

Spatial structure of places has gone through significant changes in the last 70 years, caused by modernistic approach towards urban design. This approach has brought retraction from traditional spatial form and has started introducing free form design of urban spaces since the 1960’s. Tighter urban structure has started to be applied since the 1980’s, but in a less significant way than in other developed European countries, as a result of starting mass-housing period. However modernistic approach legacy is quite heavily maintained and present in our cities. Single-use commercial areas and family-house “landscapes” located mostly on the outside of city border represent the mentioned system. In those structures, a man usually identifies himself with his own house or apartment rather than with space that commonly surrounds him. Therefore, the role of spaces, their image perceived by men and their character is more and more important. Supporting the distinctive individual character of a city and its places and the identification with districts is fundamental. Urban resident and occupant identify himself with the city and urban environment via arrangement of spaces. Social sustainability is an integral part of the effective urban development. Quality of public spaces, which support the city of neighborhoods, vibrant city and short distance city are the important pillars of sustainability. Cultural environment and the sense of place is another important dimension of sustainability. The paper is focused on mapping and evaluation of the public spaces in Bratislava with the emphasis of their social development and cultural value, as factors of their identity.

A new perspective on relativistic transformation: formulation of the differential Lorentz transformation based on first principles

International Nuclear Information System (INIS)

Huang, Young-Sea

2010-01-01

The differential Lorentz transformation is formulated solely from the principle of relativity and the invariance of the speed of light. The differential Lorentz transformation transforms physical quantities, instead of space-time coordinates, to keep laws of nature form-invariant among inertial frames. The new relativistic transformation fulfills the principle of relativity, whereas the usual Lorentz transformation of space-time coordinates does not. Furthermore, the new relativistic transformation is compatible with quantum mechanics. The formulation herein provides theoretical foundations for the differential Lorentz transformation as the fundamental relativistic transformation.

Desirable microclimate in urban public space: a case study in Amanieh Ahvaz

2011-07-01

Here are the results of field study research on thermal sensation in outdoor public spaces in Ahvaz city, Amanieh region. Ahvaz, in south Khoozestan, is one of several Iranian cities with an unpleasantly hot and semi-humid climate. In urban spaces with low thermal quality, only urgent and necessary activities take place; then people leave as soon as their business is done. In contrast, where the weather is pleasant, not only do needful activities take place, many social activities do, too. Thermal sensation is one of the determinant criteria for space attraction. In cities with unpleasant weather conditions, arranging a tolerable microclimate in public urban spaces should have high priority. Architectural climatic strategies are needed to modify the heat of summer days to a lower thermal condition level (moderate or low heat stress). Four main design strategies are described and recommended in this study.

as the boundaries between public and private spaces become increasingly fluid, interest is growing in exploring how those spaces are used as work environments, how professionals both construct and convey themselves in those spaces, and how the lines dividing spaces traditionally along public and private lines are blurred. This paper draws on literature from critical geography, organisational studies, and feminist sociology to interpret the work experiences of midwives in Ontario, Canada who provide maternity care both in hospitals and in clients' homes. qualitative design involving in-depth semi-structured interviews content coded thematically. Ontario, Canada. community midwives who practice at home and in hospital. the accounts of practicing midwives illustrate the ways in which hospital and home work spaces are sites of both compromise and resistance. With the intention of making birthing women feel more `at home', midwives describe how they attempt to recreate the woman's home in the hospital. Similarly, midwives also reorient women's homes to a certain degree into a more standardised work space for home birth attendance. Many midwives also described how they like `guests' in both settings. there seems to be a conscious or unconscious convergence of midwifery work spaces to accommodate Ontario midwives' unique model of practice. we link these findings of midwives' place of work on their experiences as workers to professional work experiences in both public and private spaces and offer suggestions for further exploration of the concept of professionals as guests in their places of work.

Explaining public support for space exploration funding in America: A multivariate analysis

Science.gov (United States)

Nadeau, François

2013-05-01

Recent studies have identified the need to understand what shapes public attitudes toward space policy. I address this gap in the literature by developing a multivariate regression model explaining why many Americans support government spending on space exploration. Using pooled data from the 2006 and 2008 General Social Surveys, the study reveals that spending preferences on space exploration are largely apolitical and associated instead with knowledge and opinions about science. In particular, the odds of wanting to increase funding for space exploration are significantly higher for white, male Babyboomers with a higher socio-economic status, a fondness for organized science, and a post-secondary science education. As such, I argue that public support for NASA's spending epitomizes what Launius termed "Apollo Nostalgia" in American culture. That is, Americans benefitting most from the old social order of the 1960s developed a greater fondness for science that makes them more likely to lament the glory days of space exploration. The article concludes with suggestions for how to elaborate on these findings in future studies.

Negotiating power relations, gender equality, and collective agency: are village health committees transformative social spaces in northern India?

Participatory health initiatives ideally support progressive social change and stronger collective agency for marginalized groups. However, this empowering potential is often limited by inequalities within communities and between communities and outside actors (i.e. government officials, policymakers). We examined how the participatory initiative of Village Health, Sanitation, and Nutrition Committees (VHSNCs) can enable and hinder the renegotiation of power in rural north India. Over 18 months, we conducted 74 interviews and 18 focus groups with VHSNC members (including female community health workers and local government officials), non-VHSNC community members, NGO staff, and higher-level functionaries. We observed 54 VHSNC-related events (such as trainings and meetings). Initial thematic network analysis supported further examination of power relations, gendered "social spaces," and the "discourses of responsibility" that affected collective agency. VHSNCs supported some re-negotiation of intra-community inequalities, for example by enabling some women to speak in front of men and perform assertive public roles. However, the extent to which these new gender dynamics transformed relations beyond the VHSNC was limited. Furthermore, inequalities between the community and outside stakeholders were re-entrenched through a "discourse of responsibility": The comparatively powerful outside stakeholders emphasized community responsibility for improving health without acknowledging or correcting barriers to effective VHSNC action. In response, some community members blamed peers for not taking up this responsibility, reinforcing a negative collective identity where participation was futile because no one would work for the greater good. Others resisted this discourse, arguing that the VHSNC alone was not responsible for taking action: Government must also intervene. This counter-narrative also positioned VHSNC participation as futile. Interventions to strengthen

Likewise, news and outreach programs accurately convey cutting-edge science and technology in a way that is attuned to audience needs. The combination of Hubble’s scientific capabilities, majestic imagery, and our deep commitment to create effective programs to share Hubble science with the education community and the public, has enabled the STScI Office of Public Outreach programs to engage 6 million students and ½ million educators per year, and 24 million online viewers per year. Hubble press releases generate approximately 5,000 online news articles per year with an average circulation of 125 million potential readers per press release news story. We will also share how best practices and lessons learned from this long-lived program are already being applied to engage a new generation of explorers in the science and technology of the James Webb Space Telescope.

Indirect transformation in reciprocal space: desmearing of small-angle scattering data from partially ordered systems

International Nuclear Information System (INIS)

Glatter, O.; Gruber, K.

1993-01-01

Indirect Fourier transformation is a widely used technique for the desmearing of instrumental broadening effects, for data smoothing and for Fourier transformation of small-angle scattering data. This technique, however, can only be applied to scattering curves with a band-limited Fourier transform, i.e. separated and noninteracting scattering centers. It can therefore not be used for scattering data from partially ordered systems. In this paper, a modified technique for partially ordered systems working in reciprocal space is presented. A peak-recognition technique allows its application to scattering functions with narrow peaks, such as the scattering functions of layered systems like lamellar stacks or strongly interacting particles. Arbitrary geometry effects and wavelength effects can be corrected. Examples of simulations show the merits and limits of this new method. One example shows its applicability to real data. (orig.)

Looking at public spaces in contemporary Rome: an anthropological perspective on the study of cities

Directory of Open Access Journals (Sweden)

Monica Postiglione

2013-01-01

Full Text Available Through the presentation of two case studies this paper aims to engage the theoretical debate on the persistence of public space in the contemporary city, and focuses the attention on the way people practice these spaces and on the policies which are regulating their uses. Starting from the description of different ways in which some urban spaces in Rome (Italy are used by two different communities of people, one mainly composed by immigrants and the other by young city users, and the diverse ways in which their different practices are seen and tolerated, the aim of this paper is to reflect on public spaces. Observing how city users practice public spaces, and analysing the way in which these practices are considered, are particularly exciting perspectives that can offer an interesting vision of the spatial and social reality of the city and of hegemonic relations which govern it.

Public space and ecology in Medellin: of the indexes of square meters for inhabitant, to the system of urban green spaces

International Nuclear Information System (INIS)

Velez Restrepo, Luis Anibal

2002-01-01

This paper constitutes a critic for green urban areas management from the landscape ecology perspective. In the context of urban public space as a reference, the decree No.1504 (1998) about urban public space in the Colombian land planning, and the agreement No.62 (1999) for the Medellin land planning 2000-2010. In the first part the conceptual limitations (from the ecological point of view) of both the decree and land planning in relation lo green areas and city-nature relationships, are highlighted. Green areas are being treated, in fact, as accessory to the urban public spaces and nowadays constitute a functionally disarticulated complex. In the second part the Medellin land planning is examined in detail to show the above-mentioned limitations especially in the absence of an ecological perspective of the urban landscape together with a lack of articulation of private open spaces and green areas. In the third part the new environmental functions of urban green areas are considered, as well as the importance of taking into account and making feasible the interactions among them, under an ecological functioning perspective. Further than an index of square meters per inhabitant. A system of green urban areas and management policies oriented to a greater naturalization are needed. The last part suggests ways of incorporating ecological criteria to the urban environmental management to the urban public space and of course to the planning and management of Medellin urban green areas and its metropolitan area

Postcolonial foldings of space and identity in science education: limits, transformations, prospects

Science.gov (United States)

Zembylas, Michalinos; Avraamidou, Lucy

2008-12-01

The four essays reviewed here constitute a worthwhile attempt to discuss various aspects of postcolonial theory, and offer constructive ideas to ongoing academic as well as public conversations with respect to whether science education can meet the challenges of educating an increasingly diverse population in the 21st century. These essays are grounded in the assumption that it is difficult to make meaningful and transformative changes in science education so that educators' efforts take into consideration the dramatic changes (i.e., diverse culture and racial origins, language, economic status etc.) of `an era of globalization' in order to meet the demands of today's schools. Each of these four essays problematizes various aspects of the social and cultural conditions of science education nowadays using different `postcolonial' ideas to interpret the implications for science learning and teaching. Although the term `postcolonial' has certainly multiple meanings in the literature, we use this term here to describe the philosophical position of these essays to challenge long-standing and hegemonic practices and taken-for-granted assumptions in science education. Through critical analysis of these essays, we engage in a dialogue with the authors, focusing on two of what seem crucial issues in understanding the potential contributions as well as the risks of postcolonial concepts in science education; these issues are space and identity. We choose these issues because they permeate all four essays in interesting and often provocative ways.

Jiang, Hongquan; Zhao, Yalin; Gao, Jianmin; Gao, Zhiyong

2017-06-01

The radiographic testing (RT) image of a steam turbine manufacturing enterprise has the characteristics of low gray level, low contrast, and blurriness, which lead to a substandard image quality. Moreover, it is not conducive for human eyes to detect and evaluate defects. This study proposes an adaptive pseudo-color enhancement method for weld radiographic images based on the hue, saturation, and intensity (HSI) color space and the self-transformation of pixels to solve these problems. First, the pixel's self-transformation is performed to the pixel value of the original RT image. The function value after the pixel's self-transformation is assigned to the HSI components in the HSI color space. Thereafter, the average intensity of the enhanced image is adaptively adjusted to 0.5 according to the intensity of the original image. Moreover, the hue range and interval can be adjusted according to personal habits. Finally, the HSI components after the adaptive adjustment can be transformed to display in the red, green, and blue color space. Numerous weld radiographic images from a steam turbine manufacturing enterprise are used to validate the proposed method. The experimental results show that the proposed pseudo-color enhancement method can improve image definition and make the target and background areas distinct in weld radiographic images. The enhanced images will be more conducive for defect recognition. Moreover, the image enhanced using the proposed method conforms to the human eye visual properties, and the effectiveness of defect recognition and evaluation can be ensured.

Applications of asynoptic space - Time Fourier transform methods to scanning satellite measurements

Science.gov (United States)

Lait, Leslie R.; Stanford, John L.

1988-01-01

A method proposed by Salby (1982) for computing the zonal space-time Fourier transform of asynoptically acquired satellite data is discussed. The method and its relationship to other techniques are briefly described, and possible problems in applying it to real data are outlined. Examples of results obtained using this technique are given which demonstrate its sensitivity to small-amplitude signals. A number of waves are found which have previously been observed as well as two not heretofore reported. A possible extension of the method which could increase temporal and longitudinal resolution is described.

A Conditional Fourier-Feynman Transform and Conditional Convolution Product with Change of Scales on a Function Space II

Directory of Open Access Journals (Sweden)

Dong Hyun Cho

2017-01-01

Full Text Available Using a simple formula for conditional expectations over continuous paths, we will evaluate conditional expectations which are types of analytic conditional Fourier-Feynman transforms and conditional convolution products of generalized cylinder functions and the functions in a Banach algebra which is the space of generalized Fourier transforms of the measures on the Borel class of L2[0,T]. We will then investigate their relationships. Particularly, we prove that the conditional transform of the conditional convolution product can be expressed by the product of the conditional transforms of each function. Finally we will establish change of scale formulas for the conditional transforms and the conditional convolution products. In these evaluation formulas and change of scale formulas, we use multivariate normal distributions so that the conditioning function does not contain present positions of the paths.

Distributional Watson transforms

For all Watson transforms W in L2(R+) a triple of Hilbert space LG ⊂ L2(R+) ⊂ L'G is constructed such that W may be extended to L'G. These results allow the construction of a triple L ⊂ L2(R+) ⊂ L', where L is a Gelfand-Fréchet space. This leads to a theory of distributional Watson transforms.

ATTENUATION OF DIFFRACTED MULTIPLES WITH AN APEX-SHIFTED TANGENT-SQUARED RADON TRANSFORM IN IMAGE SPACE

Directory of Open Access Journals (Sweden)

Alvarez Gabriel

2006-12-01

Full Text Available In this paper, we propose a method to attenuate diffracted multiples with an apex-shifted tangent-squared Radon transform in angle domain common image gathers (ADCIG . Usually, where diffracted multiples are a problem, the wave field propagation is complex and the moveout of primaries and multiples in data space is irregular. The method handles the complexity of the wave field propagation by wave-equation migration provided that migration velocities are reasonably accurate. As a result, the moveout of the multiples is well behaved in the ADCIGs. For 2D data, the apex-shifted tangent-squared Radon transform maps the 2D space image into a 3D space-cube model whose dimensions are depth, curvature and apex-shift distance.
Well-corrected primaries map to or near the zero curvature plane and specularly-reflected multiples map to or near the zero apex-shift plane. Diffracted multiples map elsewhere in the cube according to their curvature and apex-shift distance. Thus, specularly reflected as well as diffracted multiples can be attenuated simultaneously. This approach is illustrated with a segment of a 2D seismic line over a large salt body in the Gulf of Mexico. It is shown that ignoring the apex shift compromises the attenuation of the diffracted multiples, whereas the approach proposed attenuates both the specularly-reflected and the diffracted multiples without compromising the primaries.

Full Text Available Introduction. In modern society Pedagogics is no longer the domain only of tutors, school teachers and teachers of educational institutions of general and vocational training of various levels. Pedagogics, being in integration with Sociology, Philosophy, Psychology, and Cultural Science, has an impact on sociocultural life of both all society and local communities, along with well-being of children and families, and population’s quality of life. In some regions ofRussia, state bodies responsible for the administration of education and social sphere call for Social Pedagogics in order to consolidate the population; to solve local problems; to strengthen the family and government institutions. Social Pedagogics, in contrast to financial-economic measures, can not change unsatisfactory material conditions and poor housing, but contributes to the spread of ideas of humanity, mutual aid, solidarity and cooperation; then stimulates positive creation that is especially important when a person or his/her family are in difficult life situations.The aims of the publication are: to disclose the leading tendencies of socio-pedagogical and socio-cultural activity with children and families at the place of residence; to represent the results of the first stage of the project “Development and Realization of Socio-Pedagogical Potential of Territorial Communities” developed at the Institute for Study of Childhood, Family and Education of the Russian Academy of Education.Methodology and research methods. The research provided in the article is based on system-activity approach. When studying the general background of social transformations, non-system approach was used, which importance increases in connection with the growing dynamics of social changes, ambiguity of a vital context, instability and diversity of society development.

Mingling, observing, and lingering: everyday public spaces and their implications for well-being and social relations.

Cattell, Vicky; Dines, Nick; Gesler, Wil; Curtis, Sarah

2008-09-01

The rejuvenation of public spaces is a key policy concern in the UK. Drawing on a wide literature and on qualitative research located in a multi-ethnic area of East London, this paper explores their relationship to well-being and social relations. It demonstrates that ordinary spaces are a significant resource for both individuals and communities. The beneficial properties of public spaces are not reducible to natural or aesthetic criteria, however. Social interaction in spaces can provide relief from daily routines, sustenance for people's sense of community, opportunities for sustaining bonding ties or making bridges, and can influence tolerance and raise people's spirits. They also possess subjective meanings that accumulate over time and can contribute to meeting diverse needs. Different users of public spaces attain a sense of well- being for different reasons: the paper calls for policy approaches in which the social and therapeutic properties of a range of everyday spaces are more widely recognised and nurtured.

General Public Space Travel and Tourism. Volume 1; Executive Summary

Travel and tourism is one of the world's largest businesses. Its gross revenues exceed $400 billion per year in the U.S. alone, and it is our second largest employer. U.S. private sector business revenues in the space information area now approximate $10 billion per year, and are increasing rapidly. Not so in the human spaceflight area. After spending $100s of billions (1998 dollars) in public funds thereon, and continuing to spend over $5 billion per year, the government is still the only customer for human spaceflight goods and services. Serious and detailed consideration was first given to the possibility of space being opened up to trips by the general public three decades ago, and some initial attempts to do so were made a dozen years ago. But the difficulties were great and the Challenger disaster put an end to them. In recent years professional space tourism studies have been conducted in the United Kingdom, Germany and, especially, Japan. In the U.S., technological progress has been pronounced; we have had nearly a decade's experience in seeing our astronauts travel to-from low Earth orbit (LEO) safely, and we expect to commence assembly of a LEO space station housing a half-dozen people this year. Too, NASA and our space industry now have new and promising space transportation development programs underway, especially the X-33 and X-34 programs, and some related, further generation, basic technology development programs. And five private companies are also working on the design of new surface - LEO vehicles. The first professional space tourism market studies have been conducted in several countries in the past few years, especially in Japan and here. The U.S. study makes it clear that, conceptually, tens of millions of us would like to take a trip to space if we could do so with reasonable safety, comfort and reliability, and at an acceptable price. Initial businesses will address the desires of those willing to pay a greater price and accept a greater

First a description of 2+1 dimensional non-commutative (NC) phase space is presented, and then we find that in this formulation the generalized Bopp's shift has a symmetric representation and one can easily and straightforwardly define the star product on NC phase space. Then we define non-commutative Lorentz transformations both on NC space and NC phase space. We also discuss the Poincare symmetry. Finally we point out that our NC phase space formulation and the NC Lorentz transformations are applicable to any even dimensional NC space and NC phase space. (authors)

Earthquakes, public spaces and (the social construction of environmental disasters. The role of public space for risk mitigation and urban redevelopment and the role of environmental disasters for re­ assessing the ‘space of the Public’.

Directory of Open Access Journals (Sweden)

Barbara Pizzo

2014-02-01

Full Text Available This paper stems from long­lasting research dedicated to urban risk reduction through a planning approach. It focuses on public space, proposing an inversion of the usual perspective: instead of considering public spaces for risk mitigation and urban redevelopment, here the imperatives of environmental safety and urban resilience can be instrumental for exploring the meaning and role of the public space from a different, rather compelling point of view. One starting point is the concept of SUM, Strategic Urban Structure (or Framework, from the Italian “Struttura urbana minima”, which has been introduced in order to set out the contents of urban risk reduction in local administration agendas and particularly into ordinary planning processes. The SUM has been conceived both as an analytical and a normative/planning tool. Public spaces are the backbone of both urban structure and of the SUM. From their features, localization, distribution within thesettlement, and their systemic characters, largely depend the capacity of a town to positively react to a seismic event. Six case­studies of small and medium­size historic towns in the Umbria Region (one of the many Italian Regions with a high level of seismic risk, help to understand the complexities and problems related to seismic prevention within historical centres, and the conflicts between conservation of the heritage and the imperatives of environmental safety. In order to overcome possible criticalities identified in a SUM, it is necessary to provide alternatives to its functioning through redundant elements. The concept of redundancy, which is strictly related to that of uncertainty, is very interesting and promising in this field of research.

Utilizing the analytical distinction between “doing shopping” as routine practice, related to satisfaction of basic needs, and “going shopping” as pleasure and leasuretime social activity, this article demonstrates series of changes, resulting in generation of new consumer culture. These changes are compared with a range of transfigurations of the consumers’ spaces (trade spaces, which are at once places (scenes, where consumer practices deploy, and the structural condition of their possibility. According to the logic of the modern man, his focus on fast and diverse consumption and his desire of consuming everything in one place, “in one bottle” on the run, the shopping spaces are becoming the center of new industries-cultural, educational, recreational. The modern retail spaces become not only a place of shopping, but also closely incorporate into the social life of the community and turn into the centers of social life. Effectively combining and managing the various scenarios of consumption, the modern retail helps to feel and join the happiness of live communication in the overbounded with the online social contacts, but atomized world, to get rid of the feeling of emotional emptiness.

Feature-space-based FMRI analysis using the optimal linear transformation.

Science.gov (United States)

Sun, Fengrong; Morris, Drew; Lee, Wayne; Taylor, Margot J; Mills, Travis; Babyn, Paul S

2010-09-01

The optimal linear transformation (OLT), an image analysis technique of feature space, was first presented in the field of MRI. This paper proposes a method of extending OLT from MRI to functional MRI (fMRI) to improve the activation-detection performance over conventional approaches of fMRI analysis. In this method, first, ideal hemodynamic response time series for different stimuli were generated by convolving the theoretical hemodynamic response model with the stimulus timing. Second, constructing hypothetical signature vectors for different activity patterns of interest by virtue of the ideal hemodynamic responses, OLT was used to extract features of fMRI data. The resultant feature space had particular geometric clustering properties. It was then classified into different groups, each pertaining to an activity pattern of interest; the applied signature vector for each group was obtained by averaging. Third, using the applied signature vectors, OLT was applied again to generate fMRI composite images with high SNRs for the desired activity patterns. Simulations and a blocked fMRI experiment were employed for the method to be verified and compared with the general linear model (GLM)-based analysis. The simulation studies and the experimental results indicated the superiority of the proposed method over the GLM-based analysis in detecting brain activities.

Convergence and summability of Fourier transforms and Hardy spaces

CERN Document Server

Weisz, Ferenc

2017-01-01

This book investigates the convergence and summability of both one-dimensional and multi-dimensional Fourier transforms, as well as the theory of Hardy spaces. To do so, it studies a general summability method known as theta-summation, which encompasses all the well-known summability methods, such as the Fejér, Riesz, Weierstrass, Abel, Picard, Bessel and Rogosinski summations.  Following on the classic books by Bary (1964) and Zygmund (1968), this is the first book that considers strong summability introduced by current methodology. A further unique aspect is that the Lebesgue points are also studied in the theory of multi-dimensional summability. In addition to classical results, results from the past 20-30 years – normally only found in scattered research papers – are also gathered and discussed, offering readers a convenient “one-stop” source to support their work. As such, the book will be useful for researchers, graduate and postgraduate students alike.

Space charge inhibition effect of nano-Fe{sub 3}O{sub 4} on improvement of impulse breakdown voltage of transformer oil based on improved Kerr optic measurements

Transformer oil-based nanofluids (NFs) with 0.03 g/L Fe{sub 3}O{sub 4} nanoparticle content exhibit 11.2% higher positive impulse breakdown voltage levels than pure transformer oils. To study the effects of the Fe{sub 3}O{sub 4} nanoparticles on the space charge in transformer oil and to explain why the nano-modified transformer oil exhibits improved impulse breakdown voltage characteristics, the traditional Kerr electro-optic field mapping technique is improved by increasing the length of the parallel-plate electrodes and by using a photodetector array as a high light sensitivity device. The space charge distributions of pure transformer oil and of NFs containing Fe{sub 3}O{sub 4} nanoparticles can be measured using the improved Kerr electro-optic field mapping technique. Test results indicate a significant reduction in space charge density in the transformer oil-based NFs with the Fe{sub 3}O{sub 4} nanoparticles. The fast electrons are captured by the nanoparticles and are converted into slow-charged particles in the NFs, which then reduce the space charge density and result in a more uniform electric field distribution. Streamer propagation in the NFs is also obstructed, and the breakdown strengths of the NFs under impulse voltage conditions are also improved.

Equivalence of linear canonical transform domains to fractional Fourier domains and the bicanonical width product: a generalization of the space-bandwidth product.

Science.gov (United States)

Oktem, Figen S; Ozaktas, Haldun M

2010-08-01

Linear canonical transforms (LCTs) form a three-parameter family of integral transforms with wide application in optics. We show that LCT domains correspond to scaled fractional Fourier domains and thus to scaled oblique axes in the space-frequency plane. This allows LCT domains to be labeled and ordered by the corresponding fractional order parameter and provides insight into the evolution of light through an optical system modeled by LCTs. If a set of signals is highly confined to finite intervals in two arbitrary LCT domains, the space-frequency (phase space) support is a parallelogram. The number of degrees of freedom of this set of signals is given by the area of this parallelogram, which is equal to the bicanonical width product but usually smaller than the conventional space-bandwidth product. The bicanonical width product, which is a generalization of the space-bandwidth product, can provide a tighter measure of the actual number of degrees of freedom, and allows us to represent and process signals with fewer samples.

Nasution, A. D.; Zahrah, W.; Ginting, Nurlisa

2018-03-01

One of successful public open space (POS) criteria is the proper pedestrian linkage. Furthermore, a good quality POS should pay attention to pedestrian activities. This will contribute to the physical and mental health of people and enhance their quality of life. The research means to investigate how POS accommodate the pedestrians. The study takes place in twenty small towns in Sumatra Utara province, Indonesia. The analysis is a descriptive, explorative study that collects data about physical elements of POS. The survey also uses a set of questionnaire to get information about the visitors walking tradition. The result of the study shows that most of the citizens approach and get to the POS by vehicle, both cars, and motorcycles. They use their private vehicles although the distance between their houses and the POS is less than one kilometer. There is no pedestrian linkage that connects the POS with the other part of urban space. However, the POS is active by various physical activities, such as walking, playing and exercising. These events occur both in pedestrian ways in the periphery, inside the POS, and in the other spots of the POS, such as grass field or multipurpose plaza. The visitors’ vehicle tradition relates to the whole urban space which is planned in a car-oriented way. Thus, the POS becomes the only space that people can walk and enjoy the environment.

Making Space, Making Place: Digital Togetherness and the Redefinition of Migrant Identities Online

Directory of Open Access Journals (Sweden)

Sara Marino

2015-12-01

Full Text Available Immigrants have played a fundamental role in shaping the life and form of urban public spaces for generations. Their efforts, as many scholars have observed, mostly aimed at creating places of comfort in new and sometimes hostile receiving countries. In recent years, the combined contribution of the built environment and screen-based experiences have shaped migrants’ sense of community and belonging, thus making the concept of online community central to ideas about space and public life. Drawing upon a 3-year online ethnography, the article discusses to what extent new media constitute spaces of digital togetherness , where diasporic experiences and transnational identities are constructed and negotiated. It presents a transnational model of creative media consumption, which helps give insight as to how diasporas and ethnic minorities contribute to the transformation of public space in the Digital Age.

The public sector represents a significant share of all economic activity (15-25%) in Europe's industrial and transition economies. Government agencies, often the largest energy users and the biggest buyers of energy-using equipment, have significant potential to reduce energy use in their facilities and operations, while also saving taxpayer dollars and avoiding emissions of air pollutants and greenhouse gases. Public sector leadership can be the first step toward market transformation, as government creates entry markets and sets an example for other sectors to adopt efficient technologies and practices. While public sector energy efficiency has not been highlighted in EU or IEA policy compilations, many government agencies from the national to the municipal level have acted to reduce their own energy use, stimulate market demand, and provide an example to others through intergovernmental networking. Several EU projects have addressed the use of government buying power to help commercialize new technologies and to increase the market share of efficient appliances. However, additional steps are needed in order to establish public sector energy efficiency as a core element of energy and climate change policy in Europe. Based on a selected review of public sector energy efficiency activities in the EU we define five program categories: Policies and targets (energy/cost savings; pollution/CO{sub 2} reductions; measurement and verification; tracking and reporting); Public buildings (energy-saving retrofit and operation of existing facilities, as well as sustainability in new construction); Energy-efficient government procurement; Efficiency and renewable energy use in public infrastructure (transit, roads, water, and other public services); Information, training, incentives, and recognition of leadership by agencies and individuals; We discuss examples of program success, lessons learned, and future initiatives to strengthen these activities through increased

Over the last seven years the Astronomy / Astrophysics group in the Department of Physics and Astronomy of Louisiana State University has developed an exten- sive Space Science education and public outreach program. This program includes the local park district (the Recreation and Park Commission for the Parish of East Baton Rouge, BREC), the local amateur astronomer group (the Baton Rouge As- tronomical Society, BRAS), the Louisiana Arts and Science Museum (LASM), and Southern University (SU, part of the largest HBCU system in the nation). Our effort has directly led to the development of the Highland Road Park Observatory (HRPO, http://www.bro.lsu.edu/hrpo) that supports student astronomy training at LSU and SU, amateur observations and a public program for adults and children, establishment of a series of teacher professional development workshops in astronomy and physics, and the "Robots for Internet Experiences (ROBIE)" project (http://www.bro.lsu.edu/) where we have several instruments (e.g. HAM radio, radio telescope, optical tele- scopes) that can be controlled over the internet by students and teachers in the class- room along with associated lessons developed by a teacher group. In addition, this year the LASM, will be opening a new planetarium / space theater in downtown Baton Rouge, Louisiana. We are currently working to bring live views of the heavens from the HRPO telescope to audiences attending planetarium shows and will be working closely with planetarium staff to develop shows that highlight LSU astronomy / space science research. During the presentation we will provide some details about our in- dividual projects, the overall structure of our program, establishing community links and some of the lessons we learned along the way. Finally, we would like to acknowl- edge NASA, Louisiana State University, the Louisiana Systemic Initiatives Program and the Louisiana Technology Innovation Fund for their support.

Since the mid-1990's NASA's Office of Space Science (OSS) has embarked on an astronomy and space science education and public outreach (E/PO) program. Its goals are to share the excitement of space science discoveries with the public, and to enhance the quality of science, mathematics and technology education, particularly at the precollege level. A key feature of the OSS program is the direct involvement of space scientists. The majority of the funding for E/PO is allocated to flight missions, which spend 1%-2% of their total budget on E/PO, and to individual research grants. This paper presents an overview of the program's goals, objectives, philosophy, and infrastructure

Using Space Syntax to Assess Safety in Public Areas - Case Study of Tarbiat Pedestrian Area, Tabriz-Iran

Cihangir Çamur, Kübra; Roshani, Mehdi; Pirouzi, Sania

2017-10-01

In studying the urban complex issues, simulation and modelling of public space use considerably helps in determining and measuring factors such as urban safety. Depth map software for determining parameters of the spatial layout techniques; and Statistical Package for Social Sciences (SPSS) software for analysing and evaluating the views of the pedestrians on public safety were used in this study. Connectivity, integration, and depth of the area in the Tarbiat city blocks were measured using the Space Syntax Method, and these parameters are presented as graphical and mathematical data. The combination of the results obtained from the questionnaire and statistical analysis with the results of spatial arrangement technique represents the appropriate and inappropriate spaces for pedestrians. This method provides a useful and effective instrument for decision makers, planners, urban designers and programmers in order to evaluate public spaces in the city. Prior to physical modification of urban public spaces, space syntax simulates the pedestrian safety to be used as an analytical tool by the city management. Finally, regarding the modelled parameters and identification of different characteristics of the case, this study represents the strategies and policies in order to increase the safety of the pedestrians of Tarbiat in Tabriz.

Monumentality and public space in Lourenço Marques in the 1930 and 1940

2012-01-01

Full Text Available Lourenço Marques, actual Maputo (Mozambique, is subjected to a series of aesthetic interventions in its public space during the 1930s e 1940s. These seek to “monumentalize” and “portugalize” the city, responding to its recently acquired status as capital of the Colony. Two monuments appear as especially important and exemplary: the Padrão de Guerra, a lately built First War memorial (1935, and the monument to the hero of the “pacification campaigns” of the 1890s, Mouzinho de Albuquerque (1940. Around these monuments, a large number of commemorative and celebrative practices are developed. Such practices posit the monument as a “national allegory” and reproduce, in the context of a modern city, auratic and cult values. As such, they add an important dimension to the monument’s role in the authoritarian reformulation of the city’s public space as an “imperial” space, as well as in the putative hegemonization of the representations of the community imagined as a “Nation”. They allow, therefore, to approach the political-ideological use and utility of the monument within the organization of public space.

Open public spaces have been identified as important facilities to promote physical activity (PA) at the community level. The main goals of this study are to describe open public spaces user's characteristics and to explore to what extent these characteristics are associated with PA behavior. A system of direct observation was used to evaluate the PA levels on parks and squares (smaller parks) and users's characteristics (gender and age). The 4 parks and 4 squares observed were selected from neighborhoods with different socioeconomic status and environmental characteristics. The settings were observed 3 times a day, 6 days per week, during 2 weeks. More men than women were observed in parks (63.1%) and squares (70.0%) as well as more adults and adolescents than older adults and children. Users were more physically active in parks (men = 34.1%, women = 36.1%) than in squares (men = 25.5%, women 22.8%). The characteristics of public open spaces may affect PA in the observed places. Initiatives to improve PA levels in community settings should consider users' characteristics and preferences to be more effective and reach a larger number of people.

A political dimension of public budget: the councils of rights as a space for collective and plural debate

Full Text Available The consolidation of the political dimension of the Councils of Rights is linked to its understanding as plural public spaces, divergence and the constant struggle of ideas. The political dimension becomes crucial, especially in the process of defining and managing the public budget for both planning and to expand the debate on the allocation of financial resources for the implementation of public policies. It is this space that the different interests manifest themselves, becoming a field of political struggle for the appropriation of public resources in ensuring the rights and social protection of the most disenfranchised segments of society. The public budget in the spaces of advice gained a political dimension, the prospect of mere instrument accounting

Toxocarosis is a worldwide parasitic infection that affects both cats and dogs. Toxocara cati (Schrank, 1788) syn. Toxocara mystax (Zeder, 1800) prevalence was studied in faeces from stray cats collected from the open spaces of public institutions of Buenos Aires city, both building and surrounding open spaces are fenced off. Of the 465 samples obtained from March to June of 2005, 58.3% were found to have parasite eggs. The following parasites were identified from the 271 positive samples: T. cati (61.2%), Cystoisospora spp. (20.3%), Trichuris spp. (17.0%), Toxascaris leonina (15.1%), Ancylostoma spp. (14%) and Aelurostrongylus abstrusus (2.6%). T. cati prevalence was 35.7% (95% confidence interval: 31.2-40.1), with a 42.2% single isolations. The most frequent combination was T. cati and Cystoisospora spp. (9%). More than half the areas studied showed over 40% prevalence. Seventy-one percent of the collected samples were fresh with a variable moist consistency and 29% were older with a dry consistency. A statistically significant association was found between sample consistency and presence of parasites (chi2 = 10.81; p = 0.001) as also between sample consistency and presence of T. cati (chi2 = 11.27; p = 0.0007). Moist consistencies were significantly different from the rest: consistency (wet or dry) versus parasites (z = 1.95; p = 0.02) (95% confidence interval: 0.004-0.203); consistency (wet or dry) versus T. cati (z = 3.25; p = 0.0006) (95% confidence interval: 0.075-0.254). The cat population that inhabits these public green spaces contaminates the environment, thus transforming them into dangerous spaces with a variable rate for the human population that spends time in these places.

Based on the results of conducted expert assessment and sociological survey of visitors, the main problems of urban green areas were identified and also the most high-demand trends and practical recommendations for their improvement and further use were proposed.

Isometries on Banach spaces function spaces

Fleming, Richard J

2002-01-01

Fundamental to the study of any mathematical structure is an understanding of its symmetries. In the class of Banach spaces, this leads naturally to a study of isometries-the linear transformations that preserve distances. In his foundational treatise, Banach showed that every linear isometry on the space of continuous functions on a compact metric space must transform a continuous function x into a continuous function y satisfying y(t) = h(t)x(p(t)), where p is a homeomorphism and |h| is identically one.Isometries on Banach Spaces: Function Spaces is the first of two planned volumes that survey investigations of Banach-space isometries. This volume emphasizes the characterization of isometries and focuses on establishing the type of explicit, canonical form given above in a variety of settings. After an introductory discussion of isometries in general, four chapters are devoted to describing the isometries on classical function spaces. The final chapter explores isometries on Banach algebras.This treatment p...

Prisniakov, V.; Prisniakova, L.

The success in deployment of the space programs now in many respects depends on comprehension by the citizens of necessity of programs, from "space" erudition of country. Purposefulness and efficiency of the "space" teaching and educational activity depend on knowledge of relationships between separate variables of such process. The empirical methods of ``space'' well-information of the taxpayers should be supplemented by theoretical models permitting to demonstrate a ways of control by these processes. Authors on the basis of their experience of educational activity during 50- years of among the students of space-rocket profession obtain an equation of ``space" state of the society determining a degree of its knowledge about Space, about achievements in its development, about indispensable lines of investigations, rates of informatization of the population. It is supposed, that the change of the space information consists of two parts: (1) - from going of the information about practical achievements, about development special knowledge requiring of independent financing, and (2) from intensity of dissemination of the ``free" information of a general educational line going to the population through mass-media, book, in family, in educational institutions, as a part of obligatory knowledge of any man, etc. In proposed model the level space well-information of the population depends on intensity of dissemination in the society of the space information, and also from a volume of financing of space-rocket technology, from a part of population of the employment in the space-rocket programs, from a factor of education of the population in adherence to space problems, from welfare and mentality of the people, from a rate of unemployment and material inequality. Obtained in the report on these principles the equation of a space state of the society corresponds to catastrophe such as cusp, the analysis has shown which one ways of control of the public understanding of space

The Now Age, New Space, and Transforming the Exploration of Geospace

Paxton, L. J.

2017-12-01

In this talk I will discuss: 1) Changing our description of how and why we do Heliophysics (NASA) and Geospace Science (NSF) research 2) How we can take advantage of the New Space industry capabilities 3) How and why we can use the technology that has begun the transformation of our society into the "Now Age" I will discuss trends that I see that enable, if we have the will, a fundamental revitalization of the science that we aspire to do. I will focus on our opportunities to revolutionize the exploration of geospace (the region below about 1000km) and how that addresses fundamental questions about our place in the universe. Exploration of space, in particular exploration of geospace, is at a cusp - we can either attempt to continue to move forward using the same, tried and true techniques or we can embrace the "Now Age" and the capabilities enabled by the New Space industry to move forward to a fuller understanding of our world's place in the solar system. Heliophysics at NASA and Geospace Science at NSF can be recast as fundamental exploratory basic research that asks and answers questions that everyone can understand. We are in the Now Age because the human race has enabled and embraced a fundamentally different way of accessing information and, potentially gaining knowledge. For the first time, we have the capability to provide essentially all of recorded human knowledge immediately and to anyone - and people want that access "now". Even in the scientific community we expect to be able to see the latest data right now. This is enabled by the internet and ubiquitous connectivity; low cost data storage and memory; fast, low-cost computing; the means to visualize the information; advances in the way we store, catalog and retrieve information; and advances in modeling and simulation. Concomitant with the Now Age, and providing an impetus to do things "now", the New Space industry has enabled low cost access to space and has embraced a vision of human presence in

Historical earthquakes are only known to us through written recollections and so seismologists have a long experience of interpreting the reports of eyewitnesses, explaining probably why seismology has been a pioneer in crowdsourcing and citizen science. Today, Internet has been transforming this situation; It can be considered as the digital nervous system comprising of digital veins and intertwined sensors that capture the pulse of our planet in near real-time. How can both seismology and public could benefit from this new monitoring system? This paper will present the strategy implemented at Euro-Mediterranean Seismological Centre (EMSC) to leverage this new nervous system to detect and diagnose the impact of earthquakes within minutes rather than hours and how it transformed information systems and interactions with the public. We will show how social network monitoring and flashcrowds (massive website traffic increases on EMSC website) are used to automatically detect felt earthquakes before seismic detections, how damaged areas can me mapped through concomitant loss of Internet sessions (visitors being disconnected) and the benefit of collecting felt reports and geolocated pictures to further constrain rapid impact assessment of global earthquakes. We will also describe how public expectations within tens of seconds of ground shaking are at the basis of improved diversified information tools which integrate this user generated contents. A special attention will be given to LastQuake, the most complex and sophisticated Twitter QuakeBot, smartphone application and browser add-on, which deals with the only earthquakes that matter for the public: the felt and damaging earthquakes. In conclusion we will demonstrate that eyewitnesses are today real time earthquake sensors and active actors of rapid earthquake information.

Full Text Available Presently, software tools for retrosynthetic analysis are widely used by organic, medicinal, and computational chemists. Rule-based systems extensively use collections of retro-reactions (transforms. While there are many public datasets with reactions in synthetic direction (usually non-generic reactions, there are no publicly-available databases with generic reactions in computer-readable format which can be used for the purposes of retrosynthetic analysis. Here we present RetroTransformDB—a dataset of transforms, compiled and coded in SMIRKS line notation by us. The collection is comprised of more than 100 records, with each one including the reaction name, SMIRKS linear notation, the functional group to be obtained, and the transform type classification. All SMIRKS transforms were tested syntactically, semantically, and from a chemical point of view in different software platforms. The overall dataset design and the retrosynthetic fitness were analyzed and curated by organic chemistry experts. The RetroTransformDB dataset may be used by open-source and commercial software packages, as well as chemoinformatics tools.

Complexity, erotica and conflict in the urban public space

Directory of Open Access Journals (Sweden)

Enrique Díaz Álvarez

2011-09-01

Full Text Available This article highlights the importance of the urban public space, as the quintessential scenario of intercultural interaction and communication. From a context of globalisation, and from an ethical-political perspective, the author urges a reconsideration of the complexity, eroticism and conflicts that are characterised by coexistence in the city, as elements that are capable of directing dialogue, co-implication and construction of affinities between individuals who enjoy and champion the fact of being different.

Publicly Available Geosynchronous (GEO) Space Object Catalog for Future Space Situational Awareness (SSA) Studies

Science.gov (United States)

Koblick, D. C.; Shankar, P.; Xu, S.

Previously, there have been many commercial proposals and extensive academic studies regarding ground and space based sensors to assist a space surveillance network in obtaining metric observations of satellites and debris near Geosynchronous Earth Orbit (GEO). Most use physics based models for geometric constraints, lighting, and tasker/scheduler operations of sensor architectures. Under similar physics modeling assumptions, the space object catalog is often different due to proprietary standards and datasets. Lack of catalog commonality between studies creates barriers and difficulty comparing performance benefits of sensor trades. To solve this problem, we have constructed a future GEO space catalog from publicly available datasets and literature. The annual number of new payloads and rocket bodies is drawn from a Poisson distribution while the growth of the current GEO catalog is bootstrapped from the historical payload, upper stage, and debris data. We adopt a spherically symmetric explosion model and couple it with the NASA standard breakup model to simulate explosions of payloads and rocket bodies as they are the primary drivers of the debris population growth. The cumulative number of fragments follow a power-law distribution. Result from 1,000 random catalog growth simulations indicates that the GEO space object population in the year 2050 will include over 3,600 objects, nearly half of which are debris greater than 10 cm spherical diameter. The number of rocket bodies and dead payloads is projected to nearly double over the next 33 years. For comparison, the current Air Force Space Command catalog snapshot contains fewer than 50 pieces of debris and coarse Radar Cross Section (RCS) estimates which include: small, medium, and large. The current catalog may be sufficient for conjunction studies, but not for analyzing future sensor system performance. The 2050 GEO projected catalog will be available online for commercial/academic research and development.

Space applications have evolved to play a significant role in disaster relief by providing services including remote sensing imagery for mitigation and disaster damage assessments; satellite communication to provide access to medical services; positioning, navigation, and timing services; and data sharing. Common issues identified in past disaster response and relief efforts include lack of communication, delayed ordering of actions (eg, evacuations), and low levels of preparedness by authorities during and after disasters. We briefly summarize the Space for Health (S4H) Team Project, which was prepared during the Space Studies Program 2014 within the International Space University. The S4H Project aimed to improve the way space assets and experiences are used in support of public health during disaster relief efforts. We recommend an integrated solution based on nano-satellites or a balloon communication system, mobile self-contained relief units, portable medical scanning devices, and micro-unmanned vehicles that could revolutionize disaster relief and disrupt different markets. The recommended new system of coordination and communication using space assets to support public health during disaster relief efforts is feasible. Nevertheless, further actions should be taken by governments and organizations in collaboration with the private sector to design, test, and implement this system.

2016-07-01

Full Text Available In the current period, followed by the industrial revolution, the damaging effects of the one-dimensional attitude towards the environment caused by human have had countless hazards. To cope with these risks, the respect and protection of environmental values has attracted today's urban human attention once again and the issues about the human right to a decent, safe and healthy environment which is called briefly" environmental rights ", have widely been discussed. In fact, this research is formed on the basis of the principle that the right to a healthy environment, must be respected in the design of public spaces and the legal aspects of this principle must be considered in dealing with these spaces, so one of the necessary contexts to the conversion of today’s public spaces to valuable urban places would be provided. Therefore, in this study the human right to a healthy, safe and decent environment and the related concepts has been reviewed and the role of the environment in the process of transforming urban spaces to urban places has been discussed. This study also emphasizes on the role of the noise pollution of the urban public spaces as one of the threatening factors of the right to the environment, in the inefficiency and disorder in the process of the conversion of these spaces to public places and while reviewing the laws to reduce such pollution in urban public spaces, it stresses the necessity of considering these rules in designing the urban public spaces. This study uses descriptive and analytic research methodology and investigation techniques of literature review by using library studies.

Cyclic transformation of orbital angular momentum modes

International Nuclear Information System (INIS)

Schlederer, Florian; Krenn, Mario; Fickler, Robert; Malik, Mehul; Zeilinger, Anton

2016-01-01

The spatial modes of photons are one realization of a QuDit, a quantum system that is described in a D-dimensional Hilbert space. In order to perform quantum information tasks with QuDits, a general class of D-dimensional unitary transformations is needed. Among these, cyclic transformations are an important special case required in many high-dimensional quantum communication protocols. In this paper, we experimentally demonstrate a cyclic transformation in the high-dimensional space of photonic orbital angular momentum (OAM). Using simple linear optical components, we show a successful four-fold cyclic transformation of OAM modes. Interestingly, our experimental setup was found by a computer algorithm. In addition to the four-cyclic transformation, the algorithm also found extensions to higher-dimensional cycles in a hybrid space of OAM and polarization. Besides being useful for quantum cryptography with QuDits, cyclic transformations are key for the experimental production of high-dimensional maximally entangled Bell-states. (paper)

Regulating public space on the beachfronts of Rio de Janeiro.

Science.gov (United States)

Godfrey, Brian J; Arguinzoni, Olivia M

2012-01-01

Despite the fortification of buildings, streets, and public squares, Rio de Janeiro's beaches remain widely regarded as democratic spaces of social diversity and accessibility. Our study revisits the question of Rio's “democratic” beachfronts, based on local interviews, field observations, official reports, and newspaper accounts. We focus on historical and contemporary perceptions of planning, privatization, and public-order programs on the city's southern seaside. Institutional discourses have justified increasing regulation to combat threats of disorder and insecurity. While residents value the relative openness of beachfronts, they also acknowledge issues of safety, social segmentation, and subtle forms of bias. The public generally applauds recent “Shock of Order” policing and commercial revitalization, although critics lament the loss of traditional freedoms for informal beach vendors and casual sports. These paradoxes highlight enduring tensions between social order and hierarchy on one hand, and democratic rights and equality on the other.

The discussion draws on ethnographic studies into journeys, which entangle at the transit site,as well as re-design studio experiments. These draw to the foreground of design...... social and cultural life. Third, I draw on my studies into journeys at the site to learn about the spatial practicings of the site and of the properties and possibilities of the urban space design. Fourth, I explore in written text and drawing re-design potentials. And last, I sum up propositions...... considerations the engagement between the wayfarer and the environment. The paper is structured in five sections. I set out by introducing the traffic segregated transit site. Second, I outline and argue for the design challenge: to re-design the transit site as an important public space – a central part of our...

Present day public space through the prism of resistance forms to participative injunction. The case of public debates on the electronuclear program

International Nuclear Information System (INIS)

Chambru, Mikael

2011-10-01

This paper proposes to analyze the types of commitments used in the public sphere by the anti-nuclear movements to resist the injunction of participatory public debates. These debates, related to the nuclear power policy, are implemented under the aegis of the National Commission of Public Debate (CNDP). Using a socio-historical approach, we contextualize the implementation of participative tools and the forms of resistance against them in a longer perspective and beyond these institutional participative mechanisms. Analyzing this form of communication and the information issues at stake, the social processes and the political strategies of actors constitute the next step in our work. Doing so enables us to improve the common understanding, through the prism of activist commitment, of the modern transformations of the public sphere. (author)

Seeking Meaning, Living Authenticity and Leadership in Public Space. A Philosophical Perspective

Directory of Open Access Journals (Sweden)

Sandu FRUNZĂ

2018-02-01

Full Text Available Postmodern man has a strong drive to build a horizon of life quality, meaning, and authentic living experiences that he increasingly wishes to be part of his personal life and public life. His action in the public space is based on a special vocation to cultivate the qualities of institutional leadership and informal leadership, including public sector leaders. Every time, philosophy makes available instruments for learning, communication, meaningfulness and reality construction meant to meet the human need for authenticity. The present text conveys a few aspects by which appropriating a life philosophy may ensure leaders’ personal development and may increase their influence upon the others.

Cominsky, Lynn R.; McLin, K. M.; Simonnet, A.; Fermi E/PO Team

2013-04-01

During the past twelve years, NASA's Fermi Gamma-ray Space Telescope has supported a wide range of Education and Public Outreach (E/PO) activities, targeting K-14 students and the general public. The purpose of the Fermi E/PO program is to increase student and public understanding of the science of the high-energy Universe, through inspiring, engaging and educational activities linked to the mission’s science objectives. The E/PO program has additional more general goals, including increasing the diversity of students in the Science, Technology, Engineering and Mathematics (STEM) pipeline, and increasing public awareness and understanding of Fermi science and technology. Fermi's multi-faceted E/PO program includes elements in each major outcome category: ● Higher Education: Fermi E/PO promotes STEM careers through the use of NASA data including research experiences for students and teachers (Global Telescope Network), education through STEM curriculum development projects (Cosmology curriculum) and through enrichment activities (Large Area Telescope simulator). ● Elementary and Secondary education: Fermi E/PO links the science objectives of the Fermi mission to well-tested, customer-focused and NASA-approved standards-aligned classroom materials (Black Hole Resources, Active Galaxy Education Unit and Pop-up book, TOPS guides, Supernova Education Unit). These materials have been distributed through (Educator Ambassador and on-line) teacher training workshops and through programs involving under-represented students (after-school clubs and Astro 4 Girls). ● Informal education and public outreach: Fermi E/PO engages the public in sharing the experience of exploration and discovery through high-leverage multi-media experiences (Black Holes planetarium and PBS NOVA shows), through popular websites (Gamma-ray Burst Skymap, Epo's Chronicles), social media (Facebook, MySpace), interactive web-based activities (Space Mysteries, Einstein@Home) and activities by

Fractional finite Fourier transform.

Khare, Kedar; George, Nicholas

2004-07-01

We show that a fractional version of the finite Fourier transform may be defined by using prolate spheroidal wave functions of order zero. The transform is linear and additive in its index and asymptotically goes over to Namias's definition of the fractional Fourier transform. As a special case of this definition, it is shown that the finite Fourier transform may be inverted by using information over a finite range of frequencies in Fourier space, the inversion being sensitive to noise. Numerical illustrations for both forward (fractional) and inverse finite transforms are provided.

Beyond a lesbian space? An investigation on the intergenerational discourse surrounding lesbian public social places in Amsterdam.

Science.gov (United States)

Fobear, Katherine

2012-01-01

This article investigates intergenerational discourse on public lesbian social spaces within Amsterdam, Netherlands. The author seeks to address how lesbian women from different generations talk about lesbian social spaces in Amsterdam through anthropological ethnographic research and semistructured interviews with 20 lesbian women who have or currently are attending these places. The author also addresses the gradual decline of lesbian specific spaces in the city and the current belief that lesbian women are beyond having a public social space that services only the lesbian community. The rise in popularity of mixed gay- and lesbian-friendly bars and girl circuit parties will be identified as a key area where generational tensions and discourse are being played out. Issues pertaining to generational disagreements over lesbian identity, visibility, and space will be addressed.
