In responding, IPH identify a number of potential health impacts including providing employment opportunities through farm diversification.  Other issues include access to open space and housing located close to traditional focal points.   The Institute of Public Health in Ireland (IPH) is an all-island body which aims to improve health in Ireland, by working to combat health inequalities and influence public policies in favour of health. IPH promotes co-operation in research, training, information and policy in order to contribute to policies which tackle inequalities in health. IPH is particularly interested in the Draft Planning Policy Statement 21 due to the impact on the countryside and potential implications on health for the population of Northern Ireland. IPH conducted a Health Impact Assessment on the proposed West Tyrone Area Plan 2019 and through this work has developed extensive knowledge when looking at health and rural issues.

Al di là del fiume - attraverso il fiume: il basso corso del Ter in Catalogna

La ricerca prende in considerazione dal punto di vista dell’architettura e dell’urbanistica la relazione tra la città e il fiume che la attraversa o la lambisce; l’insediamento umano viene analizzato nel contesto del bacino idrografico al quale appartiene. La ricerca è stata sviluppata in seno alla tesi dottorale ora in fase di elaborazione presso il Departamento de Urbanismo y Ordenación del Territorio dell’Universidad Politecnica de Catalunya. La tesi ha come caso studio il tratto basso del fiume Ter in Catalogna. Nella discussione sul paesaggio urbano contemporaneo oggi la riflessione è centrata sulla città che si territorializza; la dimensione urbana interferisce con gran parte della superficie della terra facendo sfumare le tradizionali distinzioni tra urbano e non-urbano, tra spazio costruito e spazio aperto. In questo contesto, quale termine di conciliazione tra la dinamica naturale e la costruzione storica dei luoghi prodotta dall’intervento umano, il fiume si rivela uno strumento essenziale di analisi e progetto. L’obiettivo di questa ricerca è suggerire un’approssimazione al progetto della città che si sviluppa lungo il corso fluviale costruendo strumenti per la riflessione “attraverso il fiume”. Partendo dall’ipotesi che la città si insedia lungo un corso d’acqua secondo una sintassi territoriale stabilita dalla geografía e dalla geomorfologia del fiume stesso, il fine è fornire strumenti per il processo di recupero degli spazi fluviali in contesti urbanizzati. Il fiume diviene componente geografica chiave degli insediamenti dispersi e risorsa per costruirne l’abitabilità.

Watching Corn Grow: A Hedonic Study of the Iowa Landscape, april 2007

Landscape amenities can be scarce in places with large areas of open space. Intensely farmed areas with high levels of monocropping and livestock production are akin to developed open space areas and do not provide many services in terms of landscape amenities. Open space in the form of farmland is plentiful, but parks and their services are in short supply. This issue is of particular importance for public policy because it is closely linked to the impact of externalities caused by agricultural activities and to the indirect effects of land use dynamics. This study looks at the impact of landscape amenities on rural residential property values in five counties in North Central Iowa using a hedonic pricing model based on geographic information systems. The effect of cropland, pasture, forest, and developed land as land uses surrounding the property is considered, as well as the impact of proximity to recreational areas. The study also includes the effect of other disamenities, such as livestock facilities and quarries, which can be considered part of the developed open space and are a common feature of the Iowa landscape.

Carbon and oxygen isotope study of hydrothermal carbonates in the zinc-lead deposits of the San Vicente district, central Peru: A quantitative modeling on mixing processes and CO2 degassing

Carbon and oxygen isotope studies of the host and gangue carbonates of Mississippi Valley-type zinc-lead deposits in the San Vicente District hosted in the Upper Triassic to Lower Jurassic dolostones of the Pucara basin (central Peru) were used to constrain models of the ore formation. A mixing model between an incoming hot saline slightly acidic radiogenic (Pb, Sr) fluid and the native formation water explains the overall isotopic variation (delta(13)C = - 11.5 to + 2.5 parts per thousand relative to PDB and delta(18)O = + 18.0 to + 24.3 parts per thousand relative to SMOW) of the carbonate generations. The dolomites formed during the main ore stage show a narrower range (delta(13)C = - 0.1 to + 1.7 parts per thousand and delta(18)O = + 18.7 to + 23.4 parts per thousand) which is explained by exchange between the mineralizing fluids and the host carbonates combined with changes in temperature and pressure. This model of fluid-rock interaction explains the pervasive alteration of the host dolomite I and precipitation of sphalerite I. The open-space filling hydrothermal white sparry dolomite and the coexisting sphalerite II formed by prolonged fluid-host dolomite interaction and limited CO2 degassing. Late void-filling dolomite III (or calcite) and the associated sphalerite III formed as the consequence of CO2 degassing and concomitant pH increase of a slightly acidic ore fluid. Widespread brecciation is associated to CO2 outgassing. Consequently, pressure variability plays a major role in the ore precipitation during the late hydrothermal events in San Vicente. The presence of native sulfur associated with extremely carbon-light calcites replacing evaporitic sulfates (e.g., delta(13)C = - 11.5 parts per thousand), altered native organic matter and heavier hydrothermal bitumen (from - 27.0 to - 23.0 parts per thousand delta(13)C) points to thermochemical reduction of sulfate and/or thiosulfate. The delta(13)C- and delta(18)O-values of the altered host dolostone and hydrothermal carbonates, and the carbon isotope composition of the associated organic matter show a strong regional homogeneity. These results coupled with the strong mineralogical and petrographic similarities of the different MVT occurrences perhaps reflects the fact that the mineralizing processes were similar in the whole San Vicente belt, suggesting the existence of a common regional mineralizing hydrothermal system with interconnected plumbing.

Médecine de l'adolescence. Consultation garçons [Adolescent medicine male clinic]

The vast majority of Swiss adolescents see a physician at least once a year. However, a sizeable proportion of them indicate that they don't have the opportunity to address their own concerns and problems. While female adolescents have access to health care in the field of sexual and reproductive health through family planning clinics, this is not the case of adolescent males. The "clinic for boys only" is an open space for adolescent males where they can bring questions and health problems related to their body, their growth and their puberty, just as their difficulties and their fears regarding their normality, their sexuality, their feelings, sexual dysfunctions and questions related to violence within the couple. They can also get information/treatment in the area of sexually transmitted infections.

Genesis of the Jurassic carbonate-hosted Pb-Zn deposits of Jebel Ressas (North-eastern Tunisia): Evidence from mineralogy, petrography and trace metal contents and isotope (O, C, S, Pb) geochemistry

The Jebel Ressas Pb-Zn deposits in North-Eastern Tunisia occur mainly as open-space fillings (lodes, tectonic breccia cements) in bioclastic limestones of the Upper Jurassic Ressas Formation and along the contact of this formation with Triassic rocks. The galena-sphalerite association and their alteration products (cerussite, hemimorphite, hydrozincite) are set within a calcite gangue. The Triassic rocks exhibit enrichments in trace metals, namely Pb, Co and Cd enrichment in clays and Pb, Zn, Cd, Co and Cr enrichment in carbonates, suggesting that the Triassic rocks have interacted with the ore-bearing fluids associated with the Jebel Ressas Pb-Zn deposits. The delta(18)O content of calcite associated with the Pb-Zn mineralization suggests that it is likely to have precipitated from a fluid that was in equilibrium with the Triassic dolostones. The delta(34)S values in galenas from the Pb-Zn deposits range from -1.5 to +11.4%, with an average of 5.9% and standard deviation of 3.9%. These data imply mixing of thermochemically-reduced heavy sulfur carried in geothermal- and fault-stress-driven deep-seated source fluid with bacterially-reduced light sulfur carried in topography-driven meteoric fluid. Lead isotope ratios in galenas from the Pb-Zn deposits are homogenous and indicate a single upper crustal source of base-metals for these deposits. Synthesis of the geochemical data with geological data suggests that the base-metal mineralization at Jebel Ressas was formed during the Serravallian-Tortonian (or Middle-Late Miocene) Alpine compressional tectonics.

Sulfur isotope variations from orebody to hand-specimen scale at the Mezica lead-zinc deposit, Slovenia: a predominantly biogenic pattern

The Mississippi Valley-type (MVT) Pb-Zn ore district at Mezica is hosted by Middle to Upper Triassic platform carbonate rocks in the Northern Karavanke/Drau Range geotectonic units of the Eastern Alps, northeastern Slovenia. The mineralization at Mezica covers an area of 64 km(2) with more than 350 orebodies and numerous galena and sphalerite occurrences, which formed epigenetically, both conformable and discordant to bedding. While knowledge on the style of mineralization has grown considerably, the origin of discordant mineralization is still debated. Sulfur stable isotope analyses of 149 sulfide samples from the different types of orebodies provide new insights on the genesis of these mineralizations and their relationship. Over the whole mining district, sphalerite and galena have delta(34)S values in the range of -24.7 to -1.5% VCDT (-13.5 +/- 5.0%) and -24.7 to -1.4% (-10.7 +/- 5.9%), respectively. These values are in the range of the main MVT deposits of the Drau Range. All sulfide delta(34)S values are negative within a broad range, with delta(34)S(pyrite) < delta(34)S(sphalerite) < delta(34)S(galena) for both conformable and discordant orebodies, indicating isotopically heterogeneous H(2)S in the ore-forming fluids and precipitation of the sulfides at thermodynamic disequilibrium. This clearly supports that the main sulfide sulfur originates from bacterially mediated reduction (BSR) of Middle to Upper Triassic seawater sulfate or evaporite sulfate. Thermochemical sulfate reduction (TSR) by organic compounds contributed a minor amount of (34)S-enriched H(2)S to the ore fluid. The variations of delta(34)S values of galena and coarse-grained sphalerite at orefield scale are generally larger than the differences observed in single hand specimens. The progressively more negative delta(34)S values with time along the different sphalerite generations are consistent with mixing of different H(2)S sources, with a decreasing contribution of H(2)S from regional TSR, and an increase from a local H(2)S reservoir produced by BSR (i.e., sedimentary biogenic pyrite, organo-sulfur compounds). Galena in discordant ore (-11.9 to -1.7%; -7.0 +/- 2.7%, n=12) tends to be depleted in (34)S compared with conformable ore (-24.7 to -2.8%, -11.7 +/- 6.2%, n=39). A similar trend is observed from fine-crystalline sphalerite I to coarse open-space filling sphalerite II. Some variation of the sulfide delta(34)S values is attributed to the inherent variability of bacterial sulfate reduction, including metabolic recycling in a locally partially closed system and contribution of H(2)S from hydrolysis of biogenic pyrite and thermal cracking of organo-sulfur compounds. The results suggest that the conformable orebodies originated by mixing of hydrothermal saline metal-rich fluid with H(2)S-rich pore waters during late burial diagenesis, while the discordant orebodies formed by mobilization of the earlier conformable mineralization.

La diminution des espaces ouverts en Israël depuis 1948 : exploration et discussion des facteurs contribuant à un problème de société

Le présent mémoire se penche sur la diminution des espaces ouverts en Israël, un problème environnemental considéré comme l’un des plus importants par les organisations environnementales de ce pays. La situation est particulièrement préoccupante depuis le début des années 1990 alors que la superficie occupée par ces espaces s’est réduite significativement. Les craintes liées à cette évolution se sont traduites par l’implantation de plans nationaux d’aménagement visant expressément à concentrer le développement futur du pays au sein des quatre principales régions métropolitaines (Tel-Aviv, Jérusalem, Haïfa, Beer-Sheva) de manière à préserver de façon optimale les espaces ouverts restants. Plusieurs facteurs sont responsables de cette perte d’espaces ouverts. Ainsi, l’un des objectifs cet ouvrage consiste à identifier ces facteurs de même qu’à analyser dans quelle mesure ils ont influé. Par ailleurs, ce mémoire fait le point sur l’évolution de la superficie des espaces ouverts au fil des années. Finalement, le dernier chapitre aborde les enjeux actuels quant à la conservation des espaces ouverts israéliens et souligne quelques solutions proposées afin d’accroître leur protection pour le futur. Afin de dresser un portrait complet de la situation, la période étudiée s’étend de 1948, année de fondation de l’État d’Israël, à 2010.

Réduction du ruissellement par l’augmentation de surfaces perméables : évaluation de 2 scénarios d’aménagement d’un ensemble résidentiel à Laval

L’implantation répandue de nouveaux quartiers résidentiels sur le territoire de la périphérie urbaine est en partie responsable de la baisse du couvert végétal et de l’augmentation des surfaces imperméables à grande échelle. Les villes sont maintenant aux prises avec une augmentation constante de la production de ruissellement qu'elles doivent gérer au moyen d’un vaste réseau d’égouts et de canalisations. Des données sur les impacts de ces modèles de quartier résidentiel nous révèlent que cette forme d’habitat provoque la dégradation des milieux naturels et aquatiques. La présente étude vise à mettre à l’épreuve la stratégie d’aménagement de l’Open space design en comparant l’effet de trois situations d’aménagement d’ensembles résidentiels sur le coefficient de ruissellement pondéré (Cp). Les trois situations étudiées sont 1 : le développement actuel tel que conçu par le promoteur, 2 : un scénario de quartier visant la préservation des cours d’eau existants ainsi qu’une réduction des lots et des surfaces imperméables et 3 : un quartier avec des types d’habitation plus denses. Les coefficients pondérés obtenus sont respectivement de 0,50 pour le quartier actuel, de 0,40 pour le scénario 1 et de 0,34 pour le scénario 2. Au terme de cet exercice, il apparaît, d’une part, que la densification du bâti, la nature des surfaces et l’organisation spatiale peuvent concourir à diminuer la production de ruissellement d’un quartier. Cette étude permet de situer l’importance de la gestion du ruissellement dans la planification et l’aménagement du territoire.

Le sens de la croyance à l’âge séculier chez Charles Taylor : une herméneutique de l’expérience religieuse

Ce mémoire se propose d’étudier la manière nouvelle dont se présente la croyance religieuse à l’âge séculier dans la philosophie de la religion du philosophe Charles Taylor. Plus précisément, nous cherchons à démontrer que la croyance et l’incroyance possèdent les mêmes fondements phénoménologiques, qui sont à trouver du côté des questions identitaires. Afin d’y arriver, nous commençons par analyser sa redéfinition de la sécularité afin de comprendre pourquoi l’âge séculier n’est pas en soi un âge irréligieux. Nous montrerons en quoi, selon Taylor, les Occidentaux partagent un même « arrière-plan » moral et spirituel – le « cadre immanent », que nous appréhendons comme le contexte au sein duquel émergent les positions croyantes et athées. Nous présentons ensuite une brève analyse des éléments historiques et phénoménologiques du cadre immanent ainsi que de sa fonction « transcendantale », ce qui nous permet d’expliquer la raison pour laquelle Taylor soutient que la croyance et l’incroyance relèvent avant tout de l’identité morale et des considérations éthiques qui soutiennent notre vision du monde. Ici nous suivons Taylor en affirmant que ce sont toutes deux des expériences vécues qui a priori s’équivalent sur le plan rationnel. Enfin, au cœur de notre réflexion se trouve la mise en valeur d’un concept très important que Taylor développe à partir des travaux de William James, à savoir l’« espace ouvert jamesien ». Cette ouverture, rendue possible par la sécularité elle-même, vise à rendre compte d’un état de lucidité par lequel nous pouvons ressentir la force des deux options.

Freiräume auf Zeit

Zwischennutzungen sind ein Alltagsphänomen, das seit Ende der 1990er Jahre im wissenschaftlichen Kontext und der kommunalen Praxis der Stadt- und Freiraumentwicklung auffallend an Aufmerksamkeit gewinnt. Die vorliegende Arbeit widmet sich dem Phänomen aus der Perspektive der Freiraumentwicklung als kommunaler Aufgabe. Im Zentrum des Interesses steht die Frage, welche aktuelle Bedeutung Zwischennutzungen, verstanden als die vorübergehende Freiraumnutzung brachliegender Baugrundstücke, für freiraumbezogene öffentliche Aufgaben und Handlungsansätze haben bzw. welche Potentiale sie dafür bieten. Vor dem Hintergrund heterogener gesellschaftlicher und räumlicher Gegebenheiten, der Erkenntnis um eine begrenzte hoheitliche Steuerbarkeit der weiteren stadträumlichen Entwicklung und angesichts knapper Haushaltsmittel ist die kommunale Freiraumentwicklung gefordert, sich bezüglich ihrer Kernaufgaben aber auch bezüglich ihrer Rolle bei der Erfüllung dieser Aufgaben neu zu positionieren. Vermehrt werden Forderungen nach einem Abgehen von „allgemeingültigen“ Versorgungsstandards und traditionellen „Produktionsprozessen“ laut. Flexiblere Freiraumangebote sollen Gestaltungsspielräume für eigeninitiatives Handeln und wechselhafte oder neuartige Nutzungen eröffnen. Mit dem Setzen von Prioritäten, einer verstärkten Kundenorientierung und aktivierenden bzw. kooperativen Handlungsansätzen soll der schlechten Haushaltslage begegnet werden. Zwischennutzungen deuten aufgrund ihrer funktionalen, räumlichen und zeitlichen Flexibilität Möglichkeiten an, auf diese Anforderungen einzugehen. Der Blick in die Verwaltungspraxis einzelner Städte zeigt, dass Zwischennutzungen in der kommunalen Freiraumentwicklung in verschiedenen Zusammenhängen gezielt aufgegriffen werden und dabei diverse Bezüge zu diesen aktuellen Anforderungen herstellen lassen. Der Stellenwert, der ihnen beigemessen wird, reicht dabei vom Ausnahmefall bis zum bewährten Ansatz. Mit den Maßnahmen werden häufig akute bzw. kurzfristige Ziele verfolgt, etwa die vorübergehende Schaffung zusätzlicher Spiel- und Aufenthaltsmöglichkeiten oder die Aufwertung brachliegender Flächen durch extensive Gestaltungsmaßnahmen. Die Projekte sind häufig charakterisiert durch intensive Kooperationen mit anderen öffentlichen und mit nicht-öffentlichen Akteuren. Die Einbindung von Zwischennutzungen in das alltägliche Verwaltungshandeln ist allerdings auch mit diversen Schwierigkeiten verbunden, wie erste Institutionalisierungsansätze in manchen Städten zeigen. Die Verknüpfung unterschiedlicher Zeithorizonte im Planungsgeschehen, die Verbindung des temporären Phänomens Zwischennutzung mit dem traditionellerweise auf Dauerhaftigkeit ausgerichteten Aufgabenverständnis der kommunalen Freiraumentwicklung verlangt nach einer Modifizierung bisheriger Positionen und Herangehensweisen. Ein solcher Anpassungsprozess im Verwaltungshandeln lässt sich nur langfristig und schrittweise bewältigen und ist als Teil der – angesichts aktueller Entwicklungen notwendigen – Weiterentwicklung freiraumbezogener Aufgaben und Handlungsansätze zu verstehen. Zwischennutzungen können neben ihren kurzfristig umsetzbaren Funktionen einen Beitrag dazu leisten.

Integração do elemento vegetal no edificado

Esta dissertação é muito mais do que um trabalho sobre ajardinamento de edifícios, pois pretende-se que seja uma ferramenta de ajuda em benefício da transformação de milhares de metros quadrados, das coberturas e das fachadas, muitas vezes negligenciados, em espaços verdes públicos beneficiando, não somente, os promotores imobiliários mas, acima de tudo os seus ocupantes e usufrutuários, que desta forma podem tirar partido de novos espaços de estar, ao ar livre. Enquanto a cidade, ao nível térreo, apresenta um aumento de tráfego rodoviário, com inegável poluição e confusão, é possível, desta forma, usufruir de um espaço aberto. Esta dissertação procura estudar os edifícios que já integram o elemento vegetal no seu conceito e que sejam um sucesso na forma como usam o elemento vegetal, de modo a divulgar as técnicas de construção, entender as decisões dos projectistas e o impacto nos utilizadores que habitam e usufruem dos espaços – Análise-Pós-Ocupação. Esta dissertação pretende demonstrar o quanto é importante que as cidades apresentem espaços verdes para uso da população. As zonas verdes existentes nas cidades são inequivocamente um importante indicador da qualidade ambiental existente nessas mesmas cidades. As coberturas e fachadas verdes arrefecem os edifícios, capturam e filtram as águas da chuva, proporcionam habitat à vida selvagem, reduzem o efeito de estufa das cidades, proporcionam uma preciosidade estética, uma experiência recreativa e por vezes comida, para os habitantes das cidades. Pretende-se assim, focar os benefícios humanos, sociais e naturais que se obtêm ao introduzir vegetação nas paredes, terraços, pátios e coberturas dos edifícios. Assim foi considerado útil usar uma metodologia para também analisar o tipo de espécies usadas nos estudos de caso, e determinar a necessidade de uma ferramenta para que a selecção vegetal respeite critérios de biodiversidade e melhor adaptabilidade aos ecossistemas locais, sabendo de antemão que não podem nem pretendem substituir os habitats naturais, que as cidades também podem e devem apresentar.
