Prospects for the Development of Equity Release Products in Poland – Reverse Mortgage from a Cultural Perspective
Authors: Zbrojewski Piotr
Published: July 2013

At the time of crisis, which involves state funded benefits as well as an increase in public debt, the members of the European Union are forced to consolidate their budgetary expenses. The social cost, however, is extremely high, as the general public is unwilling to accept it. Demographic experts predict a decrease in the amount of people at an economically productive age, not to mention the continuously growing life expectancy. This fact will have serious economic consequences in Poland. That is why the pension system reform was initiated. The inevitable cuts in spending on welfare benefits might cause a situation in which one of the possibilities of increasing retirement benefits leads to the use of the most valuable and long-lasting assets that can be found in households - real estate. A financial instrument called reverse mortgage enables the gradual liberalization of the value of real estate and, thereby, can be used as an additional source of retirement income.

In Poland, the lack of verification by the Polish Financial Supervision Authority and legislative regulations as far as contractors and consumers are concerned, may pose a potential risk. There are two main problems, namely, the legal status of companies that offer reverse mortgages (in the case of possible bankruptcy and debt vindication) as well as issues concerning cyclic value changes on real estate markets. Because of the lack of a reverse mortgage bill, there is no institution which can control the financial situation of contractors, thereby guaranteeing the safety of potential customers.

The goal of this article is to determine the prospects of the development of reverse mortgage in Poland from a cultural perspective in terms of potential client preferences by carrying out a survey among people aged 18 to 30 (mostly students from different cities) and senior citizens over the age of 60. The other aim is to assess the influence of cultural determinants on the perception of equity release products. The author poses a question: In what way does ownership and inheritance attitude influence the volume of reverse mortgage sales?
Calendar Effects on the Real Estate Market
Authors: Brzezicka Justyna , Wiśniewski Radosław
Published: July 2013

Social and economic phenomena that rely on "soft" factors to explain the market reality supply highly valuable observations. Behavioral elements should not be omitted in analyses of the real estate market because the latest developments in behavioral sciences significantly contribute to our understanding of this market.

The popularity of behavioral research in social and economic sciences provokes an examination of the significance of behavioral analyses on the real estate market. As an object of social and economic inquiry, the property market can benefit from recent achievements in behavioral sciences which expand the explanatory potential of studies based on the neoclassical model.

This paper analyzes calendar anomalies, generally referred to as calendar effects, on the real estate market. This phenomenon has been observed on the capital market and has been investigated and described by behavioral finance. The research hypothesis tested in this study is that calendar effects are present on the real estate market.

This paper aims to:

1) review calendar effects as model phenomena on the real estate market,

2) determine whether calendar effects occur on the real estate market and, if so, identify those anomalies,

3) determine whether and to what extent the real estate market is governed by seasonal diversity,

4) explain the significance of calendar effects to the real estate market. Research goals were pursued based on analyses of real estate transactions conducted in Olsztyn between 2004 and 2011.
Level of Foreign Direct Investments and Transparency of Polish and Global Real Estate Market
Authors: Czechowska Karolina
Published: July 2013

The article aimed to present the dependencies between the transparency of the real estate market and the level of foreign investments realized on it. For developers on the real estate market, a key element, other than potential profits, may be the market’s transparency. The main feature of a transparent real estate market is easy access to credible data concerning supply and demand, rent, property prices, transactions, vacant houses and capitalization rates that could be the basis for analysis. Market transparency does not guarantee the success of an investment, but considerably influences investment decisions and the level of risk connected with them.
Land Administration Systems Development Trends – A Case Study
Authors: Dawidowicz Agnieszka , Voß Winrich , Leonard Bernd
Published: July 2013

Land management is aimed at generating optimal social, economic and environmental benefits while promoting sustainable development principles. An essential element of this process is the knowledge of the geospatial situation to support public decision-making at different levels: local, regional, national and global. Hence, there is a need for rapid access to complete and updated information about the physical characteristics of a property, rights, restrictions, responsibilities and interrelations. This information is provided by land administration systems (LAS). LAS are built and maintained by governments. The core of LAS is a multi-purpose cadastral system integrated with other spatial information systems and public registers.

In this paper, the authors present the functional architecture and the assumptions of land administration systems built in Poland and Germany. The analysis results show the specificity of the systems' design in relation to socio-economic conditions.
An attempt of integrating the systematic of urban soils into the new Russian soil classification system
Authors: Prokof'eva Tatiana , Gerasimova Maria , Lebedeva Irina , Martynenko Irina
Published: July 2013

An attempt to incorporate the popular systematic of urban soils proposed by Marina Stroganova with colleagues into the new Russian soil classification system is presented. It was facilitated by the coincidence of approaches in both systems: priority of diagnostic horizons and their combinations as criteria to identify soil types being the main units in all Russian classifications. The central image of urban soils . urbanozem . in Stroganova.s system found its due place in the order of stratozems (urbostratozem type) owing to its diagnostic horizon . urbic, which combines artificial and natural properties, and to its simultaneous formation with the parent material.

Biting midges of the subgenus Trichohelea of Forcipomyia in Poland, with keys for the determination of Polish subgenera (Diptera: Ceratopogonidae)
Authors: Alwin Alicja , Szadziewski Ryszard
Published: July 2013

Forcipomyia chaetoptera REMM, 1962 of the subgenus Trichohelea is reported for the first time in the Polish fauna. As a result the total number of biting midges recorded in Poland has increased to 219. Three species of this subgenus present in Poland (F. eques JOHANNSEN, 1908, F. tonnoiri GOETGHEBUER, 1920 and F. chaetoptera REMM, 1962) are diagnosed and illustrated, and a key for the identification of adults is proposed. Illustrated keys for the identification of the 11 subgenera of Forcipomyia occurring in Poland are also provided.
Etyka, hermeneutyka i myśl słaba. Vattimo, Rovatti, Dal / Ethics, Hermeneutics , and ‘Weak Thought’: Gianni Vattimo, Pier Aldo Rovatti, Alessandro Dal Lago
Authors: Zawadzki Andrzej
Published: July 2013

As ethics has acquired an increasingly prominent place in modern hermeneutics, this article attempts to show how ethical aspects of a broadly conceived process of interpretation function in the area of ‘weak thought’ (pensiero debole), which is one of the main developments - not just in Italy - in contemporary hermeneutics. A discussion of the concept of communication (crucial in the hermeneutic ethics of the founder of the ‘weak thought’ Gianni Vattimo, but no less significant in the work of Heidegger, Derrida and Gadamer) is followed by an examination of the contributions of Pier Aldo Rovatti and Alessandro Dal Lago. The latter have developed a distinctly ethical strand of ‘weak thought’ by concentrating on the issues of subjectivity (‘weakening’ of the subject as an ethical gesture) and language (ethical relinquishment of the quest for an absolutely clear and unequivocal manner of expression in favour of eg. metaphors, especially in philosophical discourse).
Kłopot z istnieniem Henryka Elzenberga a tradycja polskiej intymistyki modernistycznej (Brzozowski, Koniński, Kamieńska)
Authors: Kantner Katarzyna
Published: July 2013

This article tries to position Henryk Elzenberg’s Problem of Existence within the tradition of Polish modernist private diary writing. Elzenberg’s diary and occasional writings is in many ways exceptional and yet it has many parallels and links with the autobiographical works of Stanisław Brzozowski, Karol Ludwik Koniński and Anna Kamieńska. It is even possible to claim that all those texts constitute a distinct modernist subgenre, defined by its form and tone used to address issues ranging from religion and rationality to the possibility of constructing a new system of thought or finding a vocabulary capable of expressing its philosophical argument.
Proza epoki Marca i wokół Marca’68 / The Political Crisis of March 1968 in Polish Fiction
Authors: Buryła Sławomir
Published: July 2013

The article examines the representation in Polish fiction of the atmosphere of the political protests of March 1968. The relevant texts can be divided into two groups, those that were written about the time of the crisis and those that focused on the March events, as they came to be known, in retrospect. The former includes the anti-Semitic short stories and novels written by Stanisław Ryszard Dobrowolski and Roman Bratny - works whose profile makes them exceptional in postwar Polish fiction. The latter is made up of an assortment of fiction and memoirs.

Ron Schoeffel, Editor–in–Chief at UTP and founder of the project, chairs the executive committee. Professor James K. McConica, Renaissance historian and president of the Pontifical Institute of Mediaeval Studies in Toronto, is chair of the editorial board. Allan Fleming created the series design. Forty–one volumes have been published to date. The project will not be complete until the eighty-ninth volume appears.
Architecture of Amylose Supramolecules in Form of Inclusion Complexes by Phosphorylase-Catalyzed Enzymatic Polymerization
Authors: Kadokawa Jun-ichi
Published: July 2013

This paper reviews the architecture of amylose supramolecules in form of inclusion complexes with synthetic polymers by phosphorylase-catalyzed enzymatic polymerization. Amylose is known to be synthesized by enzymatic polymerization using α-d-glucose 1-phosphate as a monomer, by phosphorylase catalysis. When the phosphorylase-catalyzed enzymatic polymerization was conducted in the presence of various hydrophobic polymers, such as polyethers, polyesters, poly(ester-ether), and polycarbonates as a guest polymer, such inclusion supramolecules were formed by the hydrophobic interaction in the progress of polymerization. Because the representation of propagation in the polymerization is similar to the way that a vine of a plant grows, twining around a rod, this polymerization method for the formation of amylose-polymer inclusion complexes was proposed to be named “vine-twining polymerization”. To yield an inclusion complex from a strongly hydrophobic polyester, the parallel enzymatic polymerization system was extensively developed. The author found that amylose selectively included one side of the guest polymer from a mixture of two resemblant guest polymers, as well as a specific range in molecular weights of the guest polymers poly(tetrahydrofuran) (PTHF) in the vine-twining polymerization. Selective inclusion behavior of amylose toward stereoisomers of chiral polyesters, poly(lactide)s, also appeared in the vine-twining polymerization.
Urban Dynamics, Fractals and Generalized Entropy
Authors: Encarnação Sara , Gaudiano Marcos , Santos Francisco , Tenedório José , Pacheco Jorge
Published: July 2013

We explore the relation between the local fractal dimension and the development of the built-up area of the Northern Margin of the Metropolitan Area of Lisbon (NMAL), for the period between 1960 and 2004. To this end we make use of a Generalized Local Spatial Entropy (GLSE) function based on which urban areas can be classified into five different types. Our analysis of NMAL shows how some of the growth dynamics encountered can be linked to the plethora of social, economic and political changes that have taken place in NMAL (and Portugal), during the last 40 years, allowing for the establishment of urban planning measures to either inhibit or promote sprawl in urban areas.
Regulatory Non-Coding RNAs in Pluripotent Stem Cells
Authors: Rosa Alessandro , Brivanlou Ali
Published: July 2013

The most part of our genome encodes for RNA transcripts are never translated into proteins. These include families of RNA molecules with a regulatory function, which can be arbitrarily subdivided in short (less than 200 nucleotides) and long non-coding RNAs (ncRNAs). MicroRNAs, which act post-transcriptionally to repress the function of target mRNAs, belong to the first group. Included in the second group are multi-exonic and polyadenylated long ncRNAs (lncRNAs), localized either in the nucleus, where they can associate with chromatin remodeling complexes to regulate transcription, or in the cytoplasm, acting as post-transcriptional regulators. Pluripotent stem cells, such as embryonic stem cells (ESCs) or induced pluripotent stem cells (iPSCs), represent useful systems for modeling normal development and human diseases, as well as promising tools for regenerative medicine. To fully explore their potential, however, a deep understanding of the molecular basis of stemness is crucial. In recent years, increasing evidence of the importance of regulation by ncRNAs in pluripotent cells is accumulating. In this review, we will discuss recent findings pointing to multiple roles played by regulatory ncRNAs in ESC and iPSCs, where they act in concert with signaling pathways, transcriptional regulatory circuitries and epigenetic factors to modulate the balance between pluripotency and differentiation.

Published: July 2013

Cholesteatoma is a destructive and expanding growth of keratinizing squamous epithelium in the middle ear or petrous apex. The molecular and cellular processes of the pathogenesis of acquired middle ear cholesteatoma have not been fully understood. In this study, comparative proteomic analysis was conducted to investigate the roles of specific proteins in the pathways regarding keratinocyte proliferation in cholesteatoma. The differential proteins were detected by comparing the two-dimension electrophoresis (2-DE) maps of the epithelial tissues of 12 attic cholesteatomas with those of retroauricular skins. There were 14 upregulated proteins in the epithelial tissues of cholesteatoma in comparison with retroauricular skin. The modulation of five crucial proteins, HSP27, PRDX2, GRP75, GRP78 and GRP94, was further determined by RT-PCR, Western blot and immunohistochemistry. Phosphorylation of HSP27 at Ser-82 was identified by mass spectroscopy. The results of this study suggested that phosphorylated HSP27 is the end expression of two potential signal-transduction pathways, and together with PRDX2, they are very likely involved in the proliferation of keratinocytes in cholesteatoma. Upregulations of GRP75, GRP78 and GRP94 in keratinocytes may be able to counter endoplasmic reticulum stress, to inhibit cell apoptosis, to prevent protein unfolding and to promote cholesteatoma growth.

Published: July 2013

Intracellular fucoidanase was isolated from the marine bacterium, Formosa algae strain KMM 3553. The first appearance of fucoidan enzymatic hydrolysis products in a cell-free extract was detected after 4 h of bacterial growth, and maximal fucoidanase activity was observed after 12 h of growth. The fucoidanase displayed maximal activity in a wide range of pH values, from 6.5 to 9.1. The presence of Mg2+, Ca2+ and Ba2+ cations strongly activated the enzyme; however, Cu2+ and Zn2+ cations had inhibitory effects on the enzymatic activity. The enzymatic activity of fucoidanase was considerably reduced after prolonged (about 60 min) incubation of the enzyme solution at 45 °C. The fucoidanase catalyzed the hydrolysis of fucoidans from Fucus evanescens and Fucus vesiculosus, but not from Saccharina cichorioides. The fucoidanase also did not hydrolyze carrageenan. Desulfated fucoidan from F. evanescens was hydrolysed very weakly in contrast to deacetylated fucoidan, which was hydrolysed more actively compared to the native fucoidan from F. evanescens. Analysis of the structure of the enzymatic products showed that the marine bacteria, F. algae, synthesized an α-l-fucanase with an endo-type action that is specific for 1→4-bonds in a polysaccharide molecule built up of alternating three- and four-linked α-l-fucopyranose residues sulfated mainly at position 2.

Authors: Shan Tijiang , Sun Weibo , Wang Xiaohan , Fu Xiaoxiang , Sun Wenxian , Zhou Ligang
Published: July 2013

Ustiloxins are cyclopeptide mycotoxins produced by Villosiclava virens, the pathogenic fungus of rice false smut disease. Both resins SP207 and SP700 were screened to show the best adsorption and desorption properties for ustiloxins A and B among 20 commercial macroporous resins. Dynamic adsorption and desorption tests were carried out to optimize the process parameters. The optimal conditions for adsorption of resin SP207 were a processing volume as 32 bed volumes (BV), pH value of 4, and flow rate of 2 BV/h; and those for desorption of resin SP207 were a 40:60 (v/v) ratio of ethanol to water, an eluent volume of 4 BV, pH value of 4 and a flow rate of 3 BV/h. The optimal conditions for adsorption of resin SP700 were a processing volume of 26 BV, pH value as 4, flow rate of 2 BV/h; and those for desorption of resin SP700 were a 30:70 (v/v) ratio of ethanol to water solution as eluent, volume of 4 BV, pH value as 4 and flow rate of 2 BV/h. Under the optimal conditions; the purities of ustiloxins A and B obtained with resin SP207 increased 23.06-fold and 19.78-fold, respectively; and their recoveries were 96.67% and 81.25%; respectively. Similarly; the purities of ustiloxins A and B obtained with resin SP700 increased 14.75-fold and 15.33-fold and their recoveries were 93.65% and 88.64%; respectively. The results show that adsorption and desorption on SP207 and SP700 resins are effective strategies for purifying ustiloxins A and B. The developed methods are beneficial for large-scale preparation and purification of ustiloxins A and B from rice false smut balls.
Cyclophilins as Modulators of Viral Replication
Authors: Frausto Stephen , Lee Emily , Tang Hengli
Published: July 2013

Cyclophilins are peptidyl‐prolyl cis/trans isomerases important in the proper folding of certain proteins. Mounting evidence supports varied roles of cyclophilins, either positive or negative, in the life cycles of diverse viruses, but the nature and mechanisms of these roles are yet to be defined. The potential for cyclophilins to serve as a drug target for antiviral therapy is evidenced by the success of non-immunosuppressive cyclophilin inhibitors (CPIs), including Alisporivir, in clinical trials targeting hepatitis C virus infection. In addition, as cyclophilins are implicated in the predisposition to, or severity of, various diseases, the ability to specifically and effectively modulate their function will prove increasingly useful for disease intervention. In this review, we will summarize the evidence of cyclophilins as key mediators of viral infection and prospective drug targets.
Intelligent Metering for Urban Water: A Review
Authors: Boyle Thomas , Giurco Damien , Mukheibir Pierre , Liu Ariane , Moy Candice , White Stuart , Stewart Rodney
Published: July 2013

This paper reviews the drivers, development and global deployment of intelligent water metering in the urban context. Recognising that intelligent metering (or smart metering) has the potential to revolutionise customer engagement and management of urban water by utilities, this paper provides a summary of the knowledge-base for researchers and industry practitioners to ensure that the technology fosters sustainable urban water management. To date, roll-outs of intelligent metering have been driven by the desire for increased data regarding time of use and end-use (such as use by shower, toilet, garden, etc.) as well as by the ability of the technology to reduce labour costs for meter reading. Technology development in the water sector generally lags that seen in the electricity sector. In the coming decade, the deployment of intelligent water metering will transition from being predominantly “pilot or demonstration scale” with the occasional city-wide roll-out, to broader mainstream implementation. This means that issues which have hitherto received little focus must now be addressed, namely: the role of real-time data in customer engagement and demand management; data ownership, sharing and privacy; technical data management and infrastructure security, utility workforce skills; and costs and benefits of implementation.
α-Bromodiazoacetamides – a new class of diazo compounds for catalyst-free, ambient temperature intramolecular C–H insertion reactions
Authors: Kaupang Åsmund , Bonge-Hansen Tore
Published: July 2013

In this work, we introduce a new class of halodiazocarbonyl compounds, α-halodiazoacetamides, which through a metal-free, ambient-temperature thermolysis perform intramolecular C–H insertions to produce α-halo-β-lactams. When carried out with α-bromodiazoacetamides bearing cyclic side chains, the thermolysis reaction affords bicyclic α-halo-β-lactams, in some cases in excellent yields, depending on the ring size and substitution pattern of the cyclic amide side chains.
Les métis culturels et identitaires. Un nouveau paradigme contemporain
Authors: Sironi Françoise
Published: July 2013

À l’heure de la mondialité, émergent des constructions identitaires et des problématiques cliniques nouvelles : métissages culturels (par naissance), métissages identitaires (suite à une expérience d’acculturation, de mutation sociale, intellectuelle ou spirituelle), néo-parentalités (familles recomposées, homoparentalités, uni-parentalités), adoptions et procréations médicalement assistées, transidentités (sujets transgenres ou transsexuels). L’auteure montre en quoi la clinique des métissages constitue un nouveau paradigme permettant de penser celle des autres nouvelles constructions identitaires. La psychothérapie, dans ces cas de figure, est un accompagnement des vicissitudes d’une métamorphose identitaire. Enfin, les métis culturels et identitaires ont également une fonction politique intéressante : ce sont des passeurs de mondes.
Quels enjeux anthropologiques et éthiques pour la traduction en santé publique ?
Authors: Lkhadir Aïcha , Mestre Claire
Published: July 2013

Cet article est le fruit de l’analyse de pratiques d’interprètes intervenant en milieu hospitalier et salariés par une association, Mana, dont les missions sont le soin et la prévention auprès des populations migrantes, la recherche et la formation. Ce travail consiste, depuis désormais 2004, à offrir aux interprètes un espace de parole, à écouter et à analyser leurs récits dans une approche complémentariste anthropologique et psychologique. Cette action intervient à un moment où la question de la traduction orale dans l’institution hospitalière est devenue un besoin pressant. La présence de l’interprétariat y demeure malheureusement précaire ; cela exacerbe l’inégalité de l’accès aux soins de ces populations. Toutefois, les interventions des interprètes ne vont pas de soi, elles soulèvent plusieurs questionnements : comment vivent-ils et perçoivent-ils leur rôle dans cette nouvelle fonction ? Comment sont-ils perçus par les professionnels et quelles difficultés rencontrent-ils ? Nous nous attelons ici à mettre en évidence, à travers leurs propres paroles, les enjeux auxquels ils sont confrontés, puis nous proposons quelques pistes de travail pour ce métier en devenir.
El papel de los convenios urbanísticos en la planificación de nuevos espacios urbanos: el caso de Gáldar-Guía (Gran Canaria)
Authors: Arranz Lozano María Mercedes
Published: July 2013

En el artículo que se presenta a continuación damos a conocer las pautas del desarrollo urbano que han experimentado dos municipios de Gran Canaria, Gáldar y Guía, que, con Agaete conforman el sector noroeste de esa isla. La expansión urbana tuvo lugar fundamentalmente en la franja costera de ambos municipios, localizada por debajo de los 300 m de altitud sobre el nivel del mar, porque fue allí donde a comienzos del siglo XX se produjo un fuerte crecimiento demográfico, como resultado del desarrollo agrícola, en particular de los cultivos del plátano y de tomate; y porque a partir de los años sesenta, y más concretamente de los ochenta, los promotores inmobiliarios vieron que la transformación del suelo rural en urbano podía ser muy rentable. Este hecho originó una expansión urbana, en la franja espacial mencionada mediante la utilización de una norma legal como es el Convenio Urbanístico. Con ella se hacía abstracción de las Normas Subsidiarias de planificación y además se producía una gran connivencia de actuación entre los poderes locales y los promotores inmobiliarios. Todo ello con el fin de garantizar los intereses particulares de estos últimos, por delante del bien general de la comunidad, en estos municipios.

[fr] L’article que nous présentons ci de suite révèle quelles furent les normes qui favorisèrent le développement urbain de deux municipalités de la Grande Canarie : Gáldar et Guía, qui, avec Agaete, constituent le secteur Nord-Ouest de l’île. L’expansion urbaine eut lieu essentiellement le long de la frange côtière des deux villes, située à moins de 300 m d’altitude au-dessus du niveau de la mer. En effet, au début du XXe siècle, celles- ci avaient enregistré une forte croissance démographique due au développement de l’agriculture et, en particulier, des cultures de bananes et de tomates ; d’autre part, à partir des années soixante, et surtout dans les années quatre-vingt, les promoteurs immobiliers virent que la transformation du sol rural en sol urbain pouvait être très rentable. Cela provoqua un étalement urbain le long de la bande littorale grâce à l’utilisation d’une norme légale : la Convention d’urbanisme. Celle-ci permettait d’ignorer les Normes Subsidiaires d’aménagement urbain, alors qu’une importante connivence d’action se produisait entre les pouvoirs locaux de ces deux municipalités et les promoteurs immobiliers, afin d’assurer les intérêts particuliers de ces derniers par-dessus l’intérêt général de la communauté.

La Sierra de Córdoba constituye un ámbito espacial diferenciado en la provincia y en el conjunto de la Península. El estudio de la dinámica demográfica en la etapa precensal y las diferencias regionales que presentan constituyen los objetivos principales del presente trabajo. Desde un punto de vista cuantitativo la población experimenta un crecimiento que hizo posible un cenit de ocupación. Este despegue demográfico sin precedentes en las comarcas estudiadas debemos relacionarlo con el proceso de evolución demográfica positiva que pese a todo, en estos espacios interiores, se realizó a un ritmo inferior.

[fr] La Sierra de Córdoba constitue un domaine spatial différencié, non seulement dans la région mais aussi dans l’ensemble de la péninsule Ibérique. L’étude de la dynamique démographique pendant la période préalable au recensement, ainsi que des différences régionales existantes, constitue le principal objectif de cette étude. D’un point de vue quantitatif, la population connait une croissance qui a rendu possible une occupation maximale. Cet essor démographique sans précédents dans les régions étudiées doit être mis en rapport avec le processus d’évolution démographique positif qui, malgré tout, s’est produit à un rythme plus lent dans ces espaces intérieurs.

En los estudios sobre la conformación de sistemas productivos empresariales se olvida cada vez más, la significación que puede tener para su conformación y éxito la presencia de materia prima cercana. Es cierto, que los avances en los medios de transporte, entre otros condicionantes, facilitan que se aleje el lugar de transformación del de suministro de la materia prima. Sin embargo, en muchas actividades la presencia fabril está todavía muy condicionada por la localización y características de los materiales con los que fabricar. Un buen ejemplo es la industria de la madera. En concreto este artículo se centra en mostrar la relación, significación y potencialidad económica de la materia prima forestal y la industria de transformación de la madera en Galicia.

[fr] Les études sur la formation des systèmes productifs commerciaux oublient de plus en plus l’importance que peut avoir pour leur formation et leur succès la présence proche de matières premières. Il est vrai que les progrès des moyens de transport, parmi d’autres autres conditions, facilitent l’éloignement du lieu de transformation de celui d’approvisionnement de la matière première. Cependant, en de nombreuses activités, la présence d’usines est encore fortement influencée par l’emplacement et les caractéristiques des matériaux à employer. Un bon exemple est celui de l’industrie du bois. Cet article prétend, en particulier, montrer la relation, la signification et le potentiel économique des matières premières forestières et de l’industrie de transformation du bois en Galice.

La teoría de las convenciones ofrece un marco científico adecuado para analizar los criterios de calidad de consumidores y productores. El sector del vino se orienta hacia la diferenciación por la calidad. El objetivo de la investigación es identificar los criterios de calidad vigentes en el mercado del vino y las estrategias que siguen las empresas para alcanzarlos.
Dentro del marco de la teoría de las convenciones se ha diseñado un conjunto de variables estadísticas que, una vez normalizadas como números Z, sirven como indicadores de las estrategias de las denominaciones de origen vitivinícolas en su búsqueda de la calidad. Dicho conjunto se ha puesto a prueba mediante un estudio de caso sobre las denominaciones de origen aragonesas y se han identificado modelos diferentes, unos centrados en convenciones concretas (industriales en Cariñena, domésticas en Calatayud) y otros abiertos a distintas categorías de convenciones (Somontano y Campo de Borja).

Published: July 2013

El espacio rural de la Región Metropolitana de Santiago de Chile es una combinación de factores naturales, sociales, económicos y técnicos que dan origen a diversos territorios. Si consideramos aquellos donde el recurso hídrico tiene un papel predominante en el desarrollo de las actividades agrícolas, se pueden identificar distintos «territorios hídricos» en las áreas de Tiltil, Valle de Mallarauco y San Pedro de Melipilla. El estudio de estos casos permitió poner en evidencia y discutir un cierto número de puntos importantes concernientes al enfoque territorial de los recursos hídricos y de la gestión del agua en un modelo que privilegia la acción de los privados, tales como: la dimensión espacial del uso agrícola de los recursos hídricos, los conflictos y problemas por su control y los consecuentes territorios hídricos que han surgido como resultado de diversas valorizaciones de un modelo de gestión liberal. Esto con la intención de contribuir, desde la Geografía, a una reflexión encaminada a lograr una gestión integral y sostenible de los recursos hídricos en Chile.

Si nous observons ceux dans lesquels les ressources hydriques jouent un rôle prédominant dans le développement des activités agricoles, plusieurs «territoires hydriques» peuvent être identifiés dans les régions de Tiltil, Valle de Ma - llarauco et San Pedro de Melipilla. L’étude de ces cas a permis de mettre en évidence et de discuter certains aspects importants concernant l’approche territoriale des ressources hydriques et la gestion de l’eau selon un modèle qui privilégie l’action des particuliers, comme la dimension spatiale de l’usage agricole des ressources hydriques, les conflits et les problèmes de contrôle et les territoires hydriques conséquents surgis comme résultat de mises en valeur diverses d’un modèle de gestion libéral. Tout cela avec le but de contribuer depuis la Géographie à une réflexion visant l’obtention d’une gestion intégrale et durable des ressources hydriques du Chili.

El objetivo de este trabajo fue evaluar la correlación entre sensores de campo e imágenes satelitales en la caracterización bio-óptica de la laguna Chasicó (Argentina) en el período febrero-abril de 2010. Los parámetros morfométricos del cuerpo de agua se obtuvieron a partir de mediciones in situ y datos satelitales. Los sensores empleados permitieron la adquisición de firmas espectrales en las que se detectaron algunas características del agua superficial: turbidez, clorofila «a» y variaciones de profundidad. Como resultado del análisis morfométrico, se obtuvo que la laguna superó los 50 km2 de extensión y presentó una forma subrectangular elongada. A partir del procesamiento de imágenes satelitales, datos de clorofila «a» y el cálculo del Índice de Vegetación de Diferencia Normalizada (en inglés, NDVI), se modeló la distribución espacial del pigmento en la laguna. El 53,2% de su área presentó entre 5 y 10 μg/l de clorofila «a», por lo que fue caracterizada como un lago mesotrófico para el período estudiado.

[fr] Le but de cette étude était d’évaluer la corrélation entre les capteurs de champ et l’imagerie satellitaire dans la caractérisation bio-optique de la lagune Chasicó (Argentine) pendant la période de février à avril 2010. Les paramètres morphométriques de la masse d’eau ont été obtenus à partir des mesures de données obtenues in situ et satellitaires. Les capteurs utilisés ont permis d’acquérir des signatures spectrales qui ont été détectées dans certaines caractéristiques de l’eau de surface : la turbidité, la chlorophylle «a» et les variations de profondeur. Comme résultat de l’analyse morphométrique, nous avons constaté que la superficie de la lagune dépassait les 50 km2 et qu’elle présentait une forme allongée subrectangulaire. À partir du traitement de l’image satellite, des données de chlorophylle «a» et du calcul de l’Indice de Végétation de la Différence Normalisée (en anglais, NDVI), nous avons modélisé la distribution spatiale du pigment dans la lagune. 53,2 % de la zone présente entre 5 et 10 g/l de chlorophylle «a», ce qui permet de la cataloguer comme un lac mésotrophe pour la période étudiée.

Fluent, a commercial CFD software, is extensively used in the current work for numerical simulations. A comprehensive study is performed on the effect of coolant injection angles on film cooling. The the temperature distribution in the inner wall, cooling effectiveness, and the velocity distribution of coolant flow with different cases is compared. Analysis on flow injection orientations is beneficial to enhance the turbine inlet temperature and improve gas turbine efficiency
A Key Management Scheme for Clustered Wireless Senor Network in Remote Field
Authors: Xu Chonghuan
Published: July 2013

Nowadays, wireless senor networks are widely applied in many remote fields such as disaster management and habitat monitoring. Clustered WSN have been proven to outperform their non-clustered counterparts in many aspects. Security is very crucial because these networks usually operate in the hazardous environments and the sensor nodes in these networks are resource-limited. Key management is one of the fundamental protocols to build a secure WSN. In this paper, we propose a light-weight key management scheme for clustered WSN. Our proposed scheme is based on LU decomposition which is less computation, memory, communication cost than the usual schemes. We also present performance analysis.

Published: July 2013

There are various significant issues in cloud computing, such as service provision, service matching and service assessment, which have attracted researchersâ?? attentions recently. QoS play an increasingly important role during the procedure of cloud-based service provision for seamless and dynamic integration of cloud-service components. In this paper, we focus on the QoS-satisfied prediction for cloud-service composited components and present a QoS-satisfied prediction model based on hidden Markov model. For a general process of cloud-service provision, if the userâ??s QoS could not be satisfied only by one cloud-service component, the component composition should be considered to provide to user, where the QoS-satisfied capability of composited components need to be proactively predicted to guarantee the userâ??s QoS. We discuss the proposed model in detail and proof the model partly. The simulation results show that our model can obtain rather high prediction accuracy rate.

Big data cleaning is one of the important research issues in cloud computing theory. The existing data cleaning algorithms assume all the data can be loaded into the main memory at one-time, which are infeasible for big data. To this end, based on the knowledge base, a data cleaning algorithm is proposed in cloud computing by Map-Reduce. It extracts atomic knowledge of the selected nodes firstly, then analyzes their relations, deletes the same objects, builds an atomic knowledge sequence based on weights, lastly cleans data according to the sequence. The experimental results show that the cloud computing environment big data algorithm is effective and feasible, and has better expansibility.

Plant maintenance is a critical role in the success of manufacturing enterprises. The concept of remote maintenance (or e-maintenance) n the industry refers to the integration of the information and communication technologies to service for plant maintenance remotely. Remote maintenance is characteristic of knowledge intensive and collaborative. To improve the efficiency of knowledge management and so as to improve the quality of remote maintenance work, a knowledge management framework was proposed. In the model, maintenance business ontology provides a common understanding for maintenance business to share information for knowledge management, and knowledge integration network describes the relationships among role knowledge, task knowledge and equipment knowledge, to achieve the integration of maintenance business and knowledge resources. At last, the paper illustrated the application of the proposed model. Results of this study can improve the level of knowledge management for remote maintenance.
