The Alps provide a high habitat diversity for plant species, structured by broad- and fine-scale abiotic site conditions. In man-made grasslands, vegetation composition is additionally affected by the type of landuse. We recorded vegetation composition in 216 parcels of grassland in 12 municipalities representing an area of 170 x 70 km in the south-eastern part of the Swiss Alps. Each parcel was characterized by a combination of altitudinal level (valley, intermediate, alp). traditional landuse (mown. grazed), current management (mown, grazed, abandoned). and Fertilization (unfertilized, fertilized). For each parcel we also assessed the abiotic factors aspect, slope, pH value, and geographic coordinates, and for each municipality annual precipitation and its cultural tradition. We analysed vegetation composition using (i) variation partitioning in RDA. (ii) cover of graminoids. non-legume forbs, and legumes, and (iii) dominance and frequency of species. Species composition was determined by, in decreasing order of variation explained. landuse, broad-scale abiotic factors, fine-scale abiotic factors. and cultural tradition. Current socio-economically motivated landuse changes, such as grazing of unfertilized former meadows or their abandonment, strongly affect vegetation composition. In our study, the frequency of characteristic meadow species was significantly smaller in grazed and even smaller in abandoned parcels than in still mown ones, suggesting less severe consequences of grazing for vegetation composition than of abandonment. Therefore. low-intensity grazing and mowing every few years should be considered valuable conservation alternatives to abandonment. Furthermore. because each landuse type was characterized by different species. a high variety of landuse types should be promoted to preserve plant species diversity in Alpine grasslands.

Besonders für Kurier-Express-Paket-Dienste (KEP) mit vielen Haltepunkten sind verfügbare Mittel zur Ladungssicherung, wie z.B. Sicherungsnetze oder Sicherheitsgurte viel zu zeitaufwendig in der Anwendung. Im vorliegenden Artikel wird die Entwicklung eines automatisierten Ladungssicherungssystems mit dreidimensionalem-vorgeformten Sicherungsnetz vorgestellt. Für die Ladungssicherung wirken zwei Kernkomponenten zusammen. Zum einen ist ein Antirutschsystem integriert, welches die Vorteile einer reibarmen Oberfläche zum Beladen und die rutschhemmende Wirkung eines haftenden Belags beim Transport ausnutzt. Zum anderen werden unterschiedlich große Transporteinheiten durch ein sich flexibel anpassendes Netz überspannt, welches aus hochfestem Material, mit integrierten Netzverkürzern besteht. Die automatische Bedienbarkeit soll vor allem bei den Fahrern die Akzeptanz für das Ladungssicherungssystem erhöhen.

The use of lashing means, for example load securing straps or nets, is often time-consuming, especially for courier, express and parcel-services (CEP) using a lot stops. The following article describes the development of an automated load securing system with a three-dimensional-preformed net. Mainly two components interact in this system. On the one hand, an anti-skid system is integrated, which uses the advantages of a low-friction surface for loading and the anti-slip properties of an adhesive coating for the transport. On the other hand, a flexibly adaptive net consisting of high-performance synthetic fibers and integrated shorteners lash different sized transport units. Especially, the automatic lashing should increase the acceptance of the drivers for the new load securing system.

In July and August 2010 floods of unprecedented impact afflicted Pakistan. The floods resulted from a series of intense multi-day precipitation events in July and early August. At the same time a series of blocking anticyclones dominated the upper-level flow over western Russia and breaking waves i.e. equatorward extrusions of stratospheric high potential vorticity (PV) air formed along the downstream flank of the blocks. Previous studies suggested that these extratropical upper-level breaking waves were crucial for instigating the precipitation events in Pakistan. Here a detailed analysis is provided of the extratropical forcing of the precipitation. Piecewise PV inversion is used to quantify the extratropical upper-level forcing associated with the wave breaking and trajectories are calculated to study the pathways and source regions of the moisture that precipitated over Pakistan. Limited-area model simulations are carried out to complement the Lagrangian analysis. The precipitation events over Pakistan resulted from a combination of favourable boundary conditions with strong extratropical and monsoonal forcing factors. Above-normal sea-surface temperatures in the Indian Ocean led to an elevated lower-tropospheric moisture content. Surface monsoonal depressions ensured the transport of moist air from the ocean towards northeastern Pakistan. Along this pathway the air parcel humidity increased substantially (60–90% of precipitated moisture) via evapotranspiration from the land surface. Extratropical breaking waves influenced the surface wind field substantially by enhancing the wind component directed towards the mountains which reinforced the precipitation.

How can a parcel of matter, or collection of particles, simultaneously compose three different objects, characterized by different modal properties? If the statue is gouged it still exists, but not exactly that piece of gold which originally occupied the statue's borders, and the (mass of) gold within that piece can survive dispersal, while the piece cannot. The solution to this "problem of coinciding objects", this paper argues, is that there is, in that space, only the statue. The properties which the piece and the mass supposedly must have, to go on being, are not properties which anything can have necessarily or essentially. Not even having that origin can be essential. There is no object of which the statue is composed, though there are objects (viz., gold atoms) and a kind of stuff (viz., gold) of which it is composed.

The Whole Atmosphere Community Climate Model (WACCM) is utilised to study the daily ozone cycle and underlying photochemical and dynamical processes. The analysis is focused on the daily ozone cycle in the middle stratosphere at 5 hPa where satellite-based trend estimates of stratospheric ozone are most biased by diurnal sampling effects and drifting satellite orbits. The simulated ozone cycle shows a minimum after sunrise and a maximum in the late afternoon. Further, a seasonal variation of the daily ozone cycle in the stratosphere was found. Depending on season and latitude, the peak-to-valley difference of the daily ozone cycle varies mostly between 3 and 5% (0.4 ppmv) with respect to the midnight ozone volume mixing ratio. The maximal variation of 15% (0.8 ppmv) is found at the polar circle in summer. The global pattern of the strength of the daily ozone cycle is mainly governed by the solar zenith angle and the sunshine duration. In addition, we find synoptic-scale variations in the strength of the daily ozone cycle. These variations are often anti-correlated to regional temperature anomalies and are due to the temperature dependence of the rate coefficients k2 and k3 of the Chapman cycle reactions. Further, the NOx catalytic cycle counteracts the accumulation of ozone during daytime and leads to an anti-correlation between anomalies in NOx and the strength of the daily ozone cycle. Similarly, ozone recombines with atomic oxygen which leads to an anti-correlation between anomalies in ozone abundance and the strength of the daily ozone cycle. At higher latitudes, an increase of the westerly (easterly) wind cause a decrease (increase) in the sunshine duration of an air parcel leading to a weaker (stronger) daily ozone cycle.

Europeanization challenges national democratic systems. As part and parcel of the broader internationalization of politics, Europeanization is associated with a shift from policymaking within majoritarian, elected representative bodies towards technocratic decisions among non-majoritarian and non-elected bodies (Kohler-Koch and Rittberger 2008, Lavenex 2013). It is thus said to weaken the influence of citizens and parliaments on the making of policies and to undermine democratic collective identity (Lavenex 2013, Schimmelfennig 2010). The weakening of national parliaments has been referred to as “de-parliamentarisation” (Goetz and Meyer-Sahling 2008) and has nurtured a broader debate regarding the democratic deficit in the EU. While not being a member of the EU, Switzerland has not remained unaffected by these changes. As discussed in the contribution by Fischer and Sciarini, state executive actors take the lead in Switzerland's European policy. They are responsible for the conduct of international negotiations, they own the treaty making power, and it is up to them to decide whether they wish to launch a negotiation with the EU. In addition, the strong take-it or leave-it character of Europeanized acts limits the room for manoeuver of the parliamentary body also in the ratification phase. Among the public, the rejection of the treaty on the European constitution has definitely closed the era of “permissive consensus” (Hooghe and Marks 2009). However, the process of European unification remains far remote from the European public. In Switzerland, the strongly administrative character of international legislation hinders public discussion (Vögeli 2007). In such a context, the media may serve as cue for the public: By delivering information about the extent and nature of Europeanized policymaking, the media enable citizens to form their own opinions and to hold their representatives accountable. In this sense media coverage may not only be considered an indicator of the information delivered to the public, but it may also enhance the democratic legitimacy of Europeanized policymaking (for a similar argument, see Tresch and Jochum 2005). While the previous contributions to this debate have examined the Europeanization of Swiss (primary and secondary) legislation, we take a closer look at two additional domestic arenas that are both supposed to be under pressure due to Europeanization: The parliament and the media. To that end, we rely on data gathered in a research project that two of us carried out in the context of the NCCR Democracy.1 While this project was primarily interested in the mediatization of decision-making processes in Switzerland, it also investigated the conditional role played by internationalization/Europeanization. For our present purposes, we shall exploit the two data-sets that were developed as part of a study of the political agenda-setting power of the media (Sciarini and Tresch 2012, 2013, Tresch et al. 2013): A data-set on issue attention in parliamentary interventions (initiatives, motions, postulates,2 interpellations and questions) and a data-set on issue attention in articles from the Neue Zürcher Zeitung (NZZ). The data covers the years 1995 to 2003 and the coding of issues followed the classification system developed in the “Policy Agendas Project” (Baumgartner and Jones 1993).

Recent evidence that dissolved organic carbon (DOC) is a significant component of the organic carbon flux below the photic layer of the ocean (1), together with verification of high respiration rates in the dark ocean (2), suggests that the downward flux of DOC may play a major role in supporting respiration there. Here we show, on the basis of examination of the relation between DOC and apparent oxygen utilization (AOU), that the DOC flux supports ~10% of the respiration in the dark ocean. The contribution of DOC to pelagic respiration below the surface mixed layer can be inferred from the relation between DOC and apparent oxygen utilization (AOU, µM O2), a variable quantifying the cumulative oxygen consumption since a water parcel was last in contact with the atmosphere. However, assessments of DOC/AOU relations have been limited to specific regions of the ocean (3, 4) and have not considered the global ocean. We assembled a large data set (N = 9824) of concurrent DOC and AOU observations collected in cruises conducted throughout the world's oceans (fig. S1, table S1) to examine the relative contribution of DOC to AOU and, therefore, respiration in the dark ocean. AOU increased from an average (±SE) 96.3 ± 2.0 µM at the base of the surface mixed layer (100 m) to 165.5 ± 4.3 µM at the bottom of the main thermocline (1000 m), with a parallel decline in the average DOC from 53.5 ± 0.2 to 43.4 ± 0.3 µM C (Fig. 1). In contrast, there is no significant decline in DOC with increasing depth beyond 1000 m depth (Fig. 1), indicating that DOC exported with overturning circulation plays a minor role in supporting respiration in the ocean interior (5). Assuming a molar respiratory quotient of 0.69, the decline in DOC accounts for 19.6 ± 0.4% of the AOU within the top 1000 m (Fig. 1). This estimate represents, however, an upper limit, because the correlation between DOC and AOU is partly due to mixing of DOC-rich warm surface waters with DOC-poor cold thermocline waters (6). Removal of this effect by regressing DOC against AOU and water temperature indicates that DOC supports only 8.4 ± 0.3% of the respiration in the mesopelagic waters.

Los proyectos de infraestructuras lineales son implantados en el territorio, y la información geográfica de estos proyectos tiene la capacidad de representar la forma, dimensiones y ubicación de estas infraestructuras, así como los límites de las diferentes propiedades que atraviesa. Esta información geográfica ayuda al entendimiento de la afección de la instalación sobre las diferentes propiedades inmuebles, y por otro lado permite cuantificar automáticamente, la magnitud de cada tipo de afección y así utilizarse como mecanismo de notificación formal a los propietarios de las parcelas afectadas. En este trabajo se presenta cómo se ha integrado en el flujo de trabajo de Red Eléctrica de España (REE), las tareas relacionadas con el cálculo de afecciones de las nuevas instalaciones de Alta Tensión, permitiendo visualizar los proyectos mediante: un visor WMS, un globo 3D mediante KML, o como un conjunto de reseñas gráficas de cada parcela. Estas soluciones han permitido optimizar los procesos de cálculo de afecciones y la generación de las Relaciones de Bienes y Derechos (RBD) afectados en distintos formatos: gráficos o alfanuméricos e interactivos 2D y 3D, multiplicándose las posibilidades de automatización y visualización, y produciendo un acercamiento entre el mundo real y el mundo virtual. Linear infrastructure projects are implemented in the territory, and geographic information of these projects has the ability to represent the shape, size and location of these infrastructures, and the limits of the different properties it crosses. This geographic information helps understanding the affection of the installation on different properties, and to automatically quantifies the magnitude of each type of affection and well used as a mechanism to formally notify owners of affected parcels. In this paper we present how the tasks related to the affection calculation of new high-voltage installations is integrated into the workflow of Red Eléctrica de España (REE), allowing to publish and then to see the projects over internet in a standardized way by: WMS viewer, a 3D globe using KML, or review a set of graphs of each parcel. These solutions have allowed us to optimize the processes of calculation of affection and the generation of the Assets and Rights (RBD) affected document across different formats or alphanumeric graphics and interactive 2D and 3D, multiplying the possibilities of automation and visualization, and producing an approach between the real and the virtual world.

El presente trabajo aborda el aprovechamiento de algunos subproductos agrícolas (bagazo de maguey y fibra de coco) y forestales (corteza de pino) en el Estado de Oaxaca (Sur de México). El objetivo principal se centra en localizar, cuantificar y caracterizar estos con vistas a su aplicación como sustratos o componentes de sustratos en cultivos ornamentales, forestales y hortícolas, y a su uso como enmiendas en cultivos tipo. Así mismo se persigue reducir el uso de la turba y la tierra de monte como sustratos mayoritarios en la actualidad. Para la localización de los subproductos se utilizaron los datos de los registros parcelarios de los productores de coco para la obtención de copra (generadores de fibra de coco) de la región costa y de los productores de mezcal (generadores del residuo de bagazo de maguey) de la región valles centrales, así como las ubicaciones de los aserraderos forestales en el Estado de Oaxaca. Se emplea un Sistema de Información Geográfica (SIG) con una cartografía digitalizada de los elementos del medio (clima, geología y suelo), de los cultivos generadores (bagazo de maguey, fibra de coco y corteza de pino), de la agricultura protegida como receptora (tomate) y de la agricultura extensiva con cultivos receptores de enmienda (café, hule, limón, mango, palma de coco y maguey). La producción anual de los residuos se cartografía y cuantifica con los siguientes resultados: bagazo de maguey 624.000 t, fibra de coco 86.000 m3 y 72.000 t de corteza de pino. Mediante el estudio de las características de los suelos de los cultivos receptores y de los requerimientos de materia orgánica de cada cultivo se calcularon las necesidades totales de materia orgánica para cada suelo. Los resultados de las cantidades globales para cada cultivo en todo el Estado muestran una necesidad total de 3.112.000 t de materia orgánica como enmienda. Con los datos obtenidos y a través de un algoritmo matemático se realiza una propuesta de localización de dos plantas de compostaje (de bagazo de maguey y fibra de coco) y cuatro plantas de compostaje de corteza de pino. Con el fin de conocer los subproductos a valorizar como sustrato o componente de sustrato se caracteriza su composición física‐química, siguiendo Normas UNE‐EN, y se analizan mediante Resonancia Magnética Nuclear (RMN). Para el acondicionamiento de bagazo de maguey y la corteza de pino se realizaron ensayos de compostaje. Al final de 241 días la temperatura y la humedad de ambos procesos se encontraban en los rangos recomendados, indicando que los materiales estaban estabilizados y con calidad para ser utilizados como sustrato o componente de sustrato. Para la fibra de coco se realizó el proceso de molienda en seco de conchas de coco provenientes de la comunidad de Río Grande Oaxaca (Principal zona productora de copra en Oaxaca). Posteriormente se emplean los materiales obtenidos como componentes para sustratos de cultivo. Se estudia el compost de bagazo de maguey y siete mezclas; el compost de corteza de pino y ocho mezclas y la fibra de coco con tres mezclas. Estos sustratos alternativos permiten obtener mezclas y reducir el uso de la tierra de monte, turba, arcilla expandida y vermiculita, siendo por tanto una alternativa sostenible para la producción en invernadero. Se elaboraron mezclas especificas para el cultivo de Lilium hibrido asiático y oriental (siete mezclas), sustratos eco‐compatibles para cultivo de tomate (nueve mezclas), para la producción de planta forestal (siete mezclas) y para la producción de plántula hortícola (ocho mezclas). Como resultados más destacados del bagazo de maguey, corteza de pino y las mezclas obtenidas se resume lo siguiente: el bagazo de maguey, con volúmenes crecientes de turba (20, 30, 50 y 60 %) y la corteza de pino, con volúmenes de turba 40 y 60%, presentan valores muy recomendados de porosidad, capacidad de aireación, capacidad de retención de humedad y equilibrio agua‐aire. Para la fibra de coco, la procedente de Río Grande presenta mejor valoración que la muestra comercial de fibra de coco de Morelos. Por último se llevó a cabo la evaluación agronómica de los sustratos‐mezclas, realizando cinco experimentos por separado, estudiando el desarrollo vegetal de cultivos tipo, que se concretan en los siguientes ensayos: 1. Producción de Lilium asiático y oriental en cama para flor de corte; 2. Producción de Lilium oriental en contenedor para flor de corte; 3. Producción de plántula forestal (Pinus greggii E y Pinus oaxacana M); 4. Producción de tomate (Solanum lycopersicum L) y 5. Producción de plántula de tomate en semillero (Solanum lycopersicum L). En relación a la producción de Lilium hibrido asiático en cama los sustratos corteza de pino (CPTU 80:20 v/v), corteza de pino + sustrato comercial (CPSC 80:20 v/v) y corteza de pino+turba+arcilla expandida+vermiculita (CPTAEV2 30:40:15:15 v/v) presentan los mejores resultados. Dichos sustratos también presentan adecuados resultados para Lilium hibrido oriental con excepción de la corteza de pino + turba (CPTU 80:20 v/v). En la producción de Lilium hibrido oriental en contenedor para flor de corte, además de los sustratos de CPSC y CPTAEV2, la mezcla de corteza de pino+turba+arcilla expandida+vermiculita (CPTAEV 70:20:5:5 v/v) manifestó una respuesta favorable. En el ensayo de producción de plántulas de Pinus greggii E y Pinus oaxacana Mirov, las mezclas con corteza de pino+turba+arcilla expandida+vermiculita (CPTAEV2 30:40:15:15 v/v) y bagazo de maguey turba+arcilla expandida+vermiculita (BMTAEV2 30:60:5:5 v/v) son una alternativa que permite disminuir el empleo de turba, arcilla expandida y vermiculita, en comparación con el sustrato testigo de turba+arcilla expandida+vermiculita (TAEV 60:30:10 v/v). En la producción de tomate (Solanum lycopersicum L) frente a la utilización actual del serrín sin compostar (SSC), las mezclas alternativas de bagazo de maguey+turba (BMT 70:30 v/v), fibra de coco de Río Grande (FCRG 100v/v) y corteza de pino+turba (CPT 70:30 v/v), presentaron los mejores resultados en rendimientos. Así mismo, en la producción de plántulas de tomate las dos mezclas alternativas de bagazo de maguey+turba+ arcilla expandida+vermiculita (BMTAEV5 50:30:10:10 v/v) y (BMTAEV6 40:40:10:10 v/v) presentaron mejores resultados que los obtenidos en la mezcla comercial (Sunshine 3), mayoritariamente utilizada en México en la producción de plántula de tomate y hortícola. ABSTRACT This paper addresses the use of some agricultural products (maguey bagasse and coconut fiber) and forestry (pine bark) in the State of Oaxaca (southern Mexico). The principal purpose is to locate, quantify and characterize these with the idea of applying them as substrates or substrate components in ornamental crops, forestry, horticultural, and their use as crop amendments. On the other hand, the reduction of peat and forest soil as main substrates is pursued. For the location of the products, registry parcel data from copra producers (coconut fiber generators) of the coastal region and mescal producers (maguey bagasse residue generators) of the central valleys region, as well as the locations of forest mills in the State of Oaxaca. A Geographic Information System (GIS) with digital mapping of environmental factors (climate, geology and soil), crop generators of residues (maguey bagasse, coconut and pine bark) receptors of amendments such as protected agriculture (tomato) and extensive agriculture crops (coffee, rubber, lemon, mango, coconut and agave). The annual production of waste is mapped and quantified with the following results: 624,000t maguey bagasse, coconut fiber 72,000 m3 and 86,000 t of pine bark. Through the study of receiving crops soils properties of and organic matter requirements of each crop, total needs of organic matter for each soil were estimated. The results of the total quantities for each crop across the state show a total of 3,112,000 t of organic matter needed as amendment. Using that data and a mathematical algorithm, the location of two composting plants (agave bagasse and coconut fiber) and four composting plants pine bark was proposed. In order to know the by‐products that were going to be used as substrates or substrate components, their physical‐chemical composition was analyzed following UNE‐EN technics. Furthermore they were analyzed by Nuclear Magnetic Resonance (NMR). For conditioning of maguey bagasse and pine bark, composting essays were conducted. At the end of 241 days the temperature and humidity of both processes were at the recommended ranges, indicating that the materials were stabilized and had reached the quality to be used as a substrate or substrate component. Coconut shells from the community of Rio Grande Oaxaca (Main copra producing area in Oaxaca) were put through a process of dry milling. Subsequently, the obtained materials were used as components for growing media. We studied the maguey bagasse compost and seven mixtures; the pine bark compost and eight blends and coconut fiber with three mixtures. These alternative substrates allow obtaining mixtures and reduce the use of forest soil, peat, vermiculite and expanded clay, making it a sustainable alternative for greenhouse production. Specific mixtures were prepared for growing Lillium, Asian and eastern hybrids (seven blends), eco‐compatible substrates for tomato (nine mixtures), for producing forest plant (seven mixtures) and for the production of horticultural seedlings (eight mixtures). Results from maguey bagasse, pine bark and mixtures obtained are summarized as follows: the maguey bagasse, with increasing volumes of peat (20, 30, 50 and 60%) and pine bark mixed with 40 and 60% peat by volume, have very recommended values of porosity, aeration capacity, water retention capacity and water‐air balance. Coconut fiber from Rio Grande had better quality than commercial coconut fiber from Morelos. Finally the agronomic evaluation of substrates‐mixtures was carried out conducting five experiments separately: 1. Production of Asiatic and Eastern Lilium in bed for cut flower, 2. Production of oriental Lillium in container for cut flower, 3.Production of forest seedlings (Pinus greggii E and Pinus oaxacana M), 4. Production of tomato (Solanum lycopersicum L) and 5. Tomato seedling production in seedbed (Solanum lycopersicum L). In relation to the production of hybrid Asian Lilium in bed, pine bark substrates (CPTU 80:20 v/v), pine bark + commercial substrate (CPSC 80:20 v/v) and pine bark + peat + expanded clay + vermiculite (CPTAEV2 30:40:15:15 v/v) showed the best results. Such substrates also have adequate results for Lilium Oriental hybrid except pine bark + peat (CPTU 80:20 v / v). In the production of Lilium oriental hybrid container for cut flower, besides the CPSC and CPTAEV2 substrates, the mixture of pine bark + peat + vermiculite expanded clay (CPTAEV 70:20:5:5 v / v) showed a favorable response. In the production of Pinus greggii E and Pinus oaxacana Mirov seedlings trial, mixtures with pine bark + peat + expanded clay + vermiculite (CPTAEV2 30:40:15:15 v/v) and maguey bagasse+ peat+ expanded clay + vermiculite (BMTAEV2 30:60:5:5 v / v) are an alternative which allows reducing the use of peat, vermiculite and expanded clay in comparison with the control substrate made of peat + expanded clay+ vermiculite (60:30 TAEV: 10 v/v). In the production of tomato (Solanum lycopersicum L), alternative mixes of maguey bagasse + peat (BMT 70:30 v/v), coconut fiber from Rio Grande (FCRG 100 v / v) and pine bark + peat (CPT 70:30 v / v) showed the best results in yields versus the current use of sawdust without compost (SSC). Likewise, in the production of tomato seedlings of the two alternative mixtures maguey bagasse + peat expanded clay + vermiculite (BMTAEV5 50:30:10:10 v/v) and (BMTAEV6 40:40:10:10 v/v) had better results than those obtained in the commercial mixture (Sunshine 3), mainly used in Mexico in tomato seedling production and horticulture.

The encounter of architecture and urbanism with parcelisation is marked with the sign of a historical debt. Parcelisation is a tremendously powerful design tool. Architecture and urban planning attest to its capacity to shape sociospatial relations across a range of scales and contexts. From Renaissance palazzi to modernist slabs, from nation-wide agrarian reforms and Haussmann’s Paris to Christopher Alexander’s new theory of urban design and Michael Webb’s Suitaloon — most of the historical revolutions and experimental projects that have shaken these fields have relied, consciously or not, on a critique and restructuration of inherited divisions of land and space. The layout of parcel patterns has a series of implications including forms of property, the divide between private and public realms, the distribution of spatial contents and uses through zoning, typological decisions and so forth. The behaviour of any urban structure depends on the tissue of plots that configures the urban fabric and many of the challenges urban design faces today —complexity, urban vitality, social equality, etc.— hinge upon the forms of land division and distribution we adopt.

El proyecto de una tienda concentra un poco de todo aquello que interesa al arquitecto: conforma una suerte de encrucijada en la que se dan cita, junto a cuestiones disciplinares que la hacen muy atractiva y ponen a prueba su habilidad como proyectista, la necesidad de aunar recursos compositivos procedentes de otros terrenos periféricos a la arquitectura para dar una respuesta adecuada a los requerimientos específicos de imagen y persuasión que la actividad comercial comporta. Las difíciles condiciones de partida, habitualmente configuraciones espaciales no excesivamente favorables, donde las preexistencias y los contornos coartan y encierran un espacio al que hay que dotar de un nuevo orden; el tamaño reducido y las posibilidades de control total de la obra que de éste se derivan; el corto plazo de tiempo y la rapidez de respuesta que la estrategia comercial impone; su posición estratégica, en relación directa con la calle, y la mayor evidencia que, por tanto, se le asigna a la fachada y al escaparate como ‘primeros anuncios’ de la actividad; la integración y el comentario recíproco entre arquitectura y objeto que tiene lugar en su seno…, son algunas de las razones que explican este interés y justifican que la tienda −ese espacio acotado tan apto para el invento y la innovación−, constituya un banco de pruebas donde poder ensayar nuevos conceptos de la arquitectura al reunir espacial y temporalmente los condicionantes ideales requeridos para la experimentación y la comprobación de hallazgos. Aunque escasas, existen en la arquitectura contemporánea tiendas que han logrado ocupar por méritos propios un lugar destacado dentro de la obra de sus autores. Entre las merecedoras de ese reconocimiento habría que citar la ‘mítica’ sastrería Kniže proyectada por Adolf Loos a comienzos del siglo XX en Viena, el Negozio Vitrum que Giuseppe Terragni diseñara en Como en los años treinta, o la sucursal londinense de las líneas aéreas de Iraq construida en los sesenta por Alison y Peter Smithson. La elección, lejos de ser gratuita, obedece a razones fundadas. Dentro de las circunstancias temporales en las que se gestaron −las tres fueron proyectadas y construidas a lo largo del pasado siglo en un arco que abarca algo más de cincuenta años (1907-1961)−, los ejemplos seleccionados aúnan toda una serie de ‘coincidencias’ entre las que no resulta difícil establecer ciertos paralelismos: las tres marcan la talla de unos creadores que fueron capaces de dedicar la misma intensidad creativa a estos temas ‘menores’, corroborando que el carácter de la arquitectura también puede hacerse grande en lo pequeño; las tres, debido al momento de madurez en el que se abordó su diseño, reflejan su condición de laboratorio experimental al servicio de los intereses proyectuales que en ese momento ocupaban la mente de los arquitectos; las tres corroboran hipótesis ya apuntadas en arquitecturas anteriores, prueban líneas de trabajo no materializadas por falta de oportunidad y testan de manera menos comprometida soluciones que luego se trasladarán a obras con mayor vocación de permanencia; obras −y esto es algo especialmente sorprendente− con las que mantuvieron una estrecha relación en el espacio y en el tiempo, convirtiéndose incluso en plataformas de experimentación paralelas: baste en este sentido con apuntar la cercanía física −a ‘metros’ de distancia− y temporal −realizadas en los mismos años− entre la sastrería Kniže (1907- 1913;1928) y la Casa en la Michaelerplatz (1910-11); la tienda Vitrum (1930) y la Casa del Fascio (1929; 1932-36) o las oficinas de venta de las Iraqi Airways (1960-61) y la sede del The Economist (1959-64). Esta potencialidad que la tienda encierra para erigirse en laboratorio de experimentación y ensayo de la arquitectura, constituye la clave de la investigación que la tesis propone. ABSTRACT A little of everything that interests the architect is concentrated in the designing of a shop: it forms a kind of crossroads bringing together, apart from certain disciplinary questions rendering it particularly attractive and testing one’s ability as a designer, the need to coordinate compositional resources from fields peripheral to architecture in order to devise an adequate response to the specific requirements of image and persuasion that are part and parcel of business activity. The difficult start-up conditions, the generally not overly favourable spatial configurations ‒where the pre-existing conditions and shape of the site encroach on and enclose a space which has to be given a new order‒, the reduced size and possibilities afforded in terms of controlling the work, the short time frame and the rapid response imposed by the business tactics and its strategic position and direct frontal relationship with the street, make the shopfront and the display window are the ‘first advertisements” of the activity, or the integration and the reciprocal commentary between architecture and what takes place within: these are but some of the reasons explaining this interest and justifying the claim that the shop –a dimensional space so well suited to invention and innovation− constitutes a test-bed for trying out new concepts of architecture, combining in space and time the ideal conditions for experiment and the examination of its findings. Albeit not numerous, there are shops in contemporary architecture which have managed on their own merit to obtain a special place among the works of their authors. Among those earning such recognition, one should mention the ‘mythical’ Kniže tailoring establishment designed by Adolf Loos at the beginning of the 20th century in Vienna, the Negozio Vitrum designed by Giuseppe Terragni in Como in the thirties, or the London offices of Iraqi Airways built in the sixties by Alison and Peter Smithson. This selection, far from gratuitous, is based on well-founded reasons. Within the circumstances of the time-frame in which they were developed −the three were designed and built during the 20th century in a period that spans just over fifty years (1907-1961)− the chosen examples bring together a whole series of ‘coincidences’ where it is not difficult to draw certain parallels: the three bear witness to the stature of creators who were capable of devoting the same creative intensity to these ‘minor’ themes, thus corroborating the fact that the nature of the architecture can also be great in less important works; the three, thanks to the moment of maturity in which their design was carried out, reflect their condition as an experimental laboratory at the service of the particular designing interests which at the time occupied the minds of these architects; the three confirm hypotheses already displayed in previous architectures, they test lines of work which had not materialised through lack of opportunity, and in a less comprised manner check solutions that were later transferred to works with a greater vocation for permanence; works −and this is something especially surprising – with which they maintained a close relationship in time and space, even becoming parallel experimental platforms: in this sense, we need only to mention the physical proximity –just metres away− and proximity in time –built within the same years− between the Kniže shop (1907-1913; 1928) and the House of Michaelerplatz (1910-11); the Vitrum shop (1930) and the Casa del Fascio (1929;1932-36); and the Iraqi Airways sales offices (1960-61) and the headquarters of The Economist (1959-64). The potential of the shop to set itself up as an experimental laboratory and architectural rehearsal constitutes the main focus of the research put forward by this thesis.

Os consumidores de baixa renda pertencentes às classes C, D e E, representam 77% da população brasileira, uma fatia de mercado até então desvalorizadas pelas empresas. Após o Plano Real estes consumidores aumentaram sua participação na aquisição de produtos e serviços, e hoje correspondem a aproximadamente 45% do consumo brasileiro. Visando atender essa grande parcela da população muitas empresas passaram a desenvolver produtos com preços inferiores, mas com qualidade confiável. O estudo investigará o potencial mercadológico destes consumidores e terá como foco principal apresentar as estratégias de comunicação desenvolvidas pelas empresas de higiene pessoal, perfumaria e cosméticos, cujos produtos são destinados aos consumidores de baixa renda.

Tropical wildlands and their biodiversity will survive in perpetuity only through their integration into human society. One protocol for integration is to explicitly recognize conserved tropical wildlands as wildland gardens. A major way to facilitate the generation of goods and services by a wildland garden is to generate a public-domain Yellow Pages for its organisms. Such a Yellow Pages is part and parcel of high-quality search-and-delivery from wildland gardens. And, as they and their organisms become better understood, they become higher quality biodiversity storage devices than are large freezers. One obstacle to wildland garden survival is that specific goods and services, such as biodiversity prospecting, lack development protocols that automatically shunt the profits back to the source. Other obstacles are that environmental services contracts have the unappealing trait of asking for the payment of environmental credit card bills and implying delegation of centralized governmental authority to decentralized social structures. Many of the potential conflicts associated with wildland gardens may be reduced by recognizing two sets of social rules for perpetuating biodiversity and ecosystems, one set for the wildland garden and one set for the agroscape. In the former, maintaining wildland biodiversity and ecosystem survival in perpetuity through minimally damaging use is paramount, while in the agroscape, wild biodiversity and ecosystems are tools for a healthy and productive agroecosystem, and the loss of much of the original is acceptable.
