A Kraft-index – kreatív városok – fenntartható vidék (The KRAFT Index: Creative Cities – Sustainable Regions)

A KRAFT-index: Kreatív városok – fenntartható vidék egy komplex mutatórendszer, amely a fejlődési tendenciát, hálózatosodást, a fontosabb szereplők együttműködési készségét és kapacitását, kreativitási potenciálját, valamint a szereplők szinergiáiból fakadó belső energiákat és lehetőségeiket jelzi. A város- és vidékfejlesztés sikerének zálogaként előtérbe állítja és méri az ún. „puha” tényezőket, úgymint a kreativitást, innovációs képességet, új tudás létrehozását, tudástranszfert, együttműködési készséget, bizalmat, kollektív kompetenciákat. A társadalmi, gazdasági és tudományos kapcsolatok és hálózatok sűrűsége, minősége és dinamizmusa a sikeres fejlődés és fejlesztés kulcsai: ezek ma már fontosabb tényezők, mint a fizikai távolság, az adminisztratív jogi határok vagy az ún. „kemény” indikátorok. Az index értékeli egy térség lehetőségeit arra, hogy az ott élők, dolgozók, alkotók és letelepedni kívánók életminőségét, a vállalatok minőségi munkaerő iránti igényét és a fenntarthatósági szempontokat egyaránt figyelembe véve fejlessze gazdaságát és versenyképességét. Három tulajdonságcsoportot mér: 1. kreativitiási és innovációs potenciál, az új tudás létrehozásának képessége, 2. társadalmi és kapcsolati tőke, hálózati potenciál és „összekapcsoltság”, valamint 3. fenntarthatósági potenciál. _____ The KRAFT Index: Creative Cities – Sustainable Regions is a complex indicator system to measure development tendencies, ‘networkedness’, cooperation inclination and capacity, creativity potential and possibilities arising from the synergies among actors. It highlights and gauges ‘soft’ factors, such as creativity, innovation capacity, knowledge production, knowledge transfer, willingness for cooperation, trust, and collective competences and perceives effective regional cooperation among economic and social actors as the measure of successful urban and rural development. The density, quality and dynamism of social, economic and academic networks are more important factors than physical distance, administrative legal barriers or ‘hard’ indicators. The index evaluates the potential of a region to develop its economy and competitiveness by considering the quality of life of its inhabitants, workers, producers and immigrants, the quality workforce requirements of companies and sustainability. It measures three groups of qualities: 1. creativity and innovation potential, the ability of knowledge production; 2. social and connection capital, network potential and connectedness; and 3. sustainability potential.

Leaf morphology scales multi-annual trends in nutrient cycling and leaf, flower, and fruiting phenology among species in the sub-tropical hardwood forests of the northern Florida Keys

The subtropical hardwood forests of southern Florida are formed by 120 frost-sensitive, broadleaved angiosperm species that range throughout the Caribbean. Previous work on a series of small sized forest component patches of a 20 km2, forest preserve in northern Key Largo indicate that a shift in species composition was associated with a 100 year forest developmental sequence, and this shift was associated with an increasingly evergreen canopy. This document investigates the underlying differences of the biology of trees that live in this habitat, and is specifically focused on the impact of leaf morphology on changing nutrient cycling patterns. Measurements of the area, thickness, dry mass, nutrient content and longevity of several leaves from 3-4 individuals of ten species were conducted in combination with a two-year leaf litter collection and nutrient analysis to determine that species with thicker, denser leaves cycled scarce nutrients up to 2-3 times more efficiently than thin leaved tree species, and the leaf thickness/density index predicts role in forest development in a parallel direction as the index predicts nutrient cycling efficiency. A three year set of observations on the relative abundance of new leaves, flowers and fruits of the same tree species provides an opportunity to evaluate the consequences the leaf morphology/nutrient cycling/forest development relationship to forest habitat quality. Results of the three documents support a mechanistic link between forest development and nutrient cycling, and suggests that older forests are likely to be better habitats based on the availability of valuable forest products like new leaves, flowers, and fruits throughout the year.

Forest Resource Islands in a Sub-tropical Marsh: Soil–Site Relationships in Everglades Hardwood Hammocks

Spatial heterogeneity in soils is often characterized by the presence of resource-enriched patches ranging in size from a single shrub to wooded thickets. If the patches persist long enough, the primary constraint on production may transition from one limiting environmental factor to another. Tree islands that are scattered throughout the Florida Everglades basin comprise nutrient-enriched patches, or resource islands, in P-limited oligotrophic marshes. We used principal component analysis and multiple regressions to characterize the belowground environment (soil, hydrology) of one type of tree island, hardwood hammocks, and examined its relationship with the three structural variables (basal area, biomass, and canopy height) indicative of site productivity. Hardwood hammocks in the southern Everglades grow on two distinct soil types. The first, consisting of shallow, organic, relatively low-P soils, is common in the seasonally flooded Marl Prairie landscape. In contrast, hammocks on islands embedded in long hydroperiod marsh have deeper, alkaline, mineral soils with extremely high P concentrations. However, this edaphic variation does not translate simply into differences in forest structure and production. Relative water depth was unrelated to all measures of forest structure and so was soil P, but the non-carbonate component of the mineral soil fraction exhibited a strong positive relationship with canopy height. The development of P-enriched forest resource islands in the Everglades marsh is accompanied by the buildup of a mineral soil; however, limitations on growth in mature islands appear to differ substantively from those that dominate incipient stages in the transformation from marsh to forest. Key words: resource island; tree

Monitoring of Tree Island Conditions in the Southern Everglades: The Effects of Hurricanes and Hydrology on the Status and Population Dynamics of Sixteen Tropical Hardwood Hammock Tree Islands

In 2005 we began a multi-year intensive monitoring and assessment study of tropical hardwood hammocks within two distinct hydrologic regions in Everglades National Park, under funding from the CERP Monitoring and Assessment Program. In serving as an Annual Report for 2010, this document, reports in detail on the population dynamics and status of tropical hardwood hammocks in Shark Slough and adjacent marl prairies during a 4-year period between 2005 and 2009. 2005-09 was a period that saw a marked drawdown in marsh water levels (July 2006 - July 2008), and an active hurricane season in 2005 with two hurricanes, Hurricane Katrina and Wilma, making landfall over south Florida. Thus much of our focus here is on the responses of these forests to annual variation in marsh water level, and on recovery from disturbance. Most of the data are from 16 rectangular permanent plots of 225-625 m2 , with all trees mapped and tagged, and bi-annual sampling of the tree, sapling, shrub, and herb layer in a nested design. At each visit, canopy photos were taken and later analyzed for determination of interannual variation in leaf area index and canopy openness. Three of the plots were sampled at 2-month intervals, in order to gain a better idea of seasonal dynamics in litterfall and litter turnover. Changes in canopy structure were monitored through a vertical line intercept method.

Life cycle assessment of advanced bioethanol production from pulp and paper sludge

This work evaluates the environmental performance of using pulp and paper sludge as feedstock for the production of second generation ethanol. An ethanol plant for converting 5400 tons of dry sludge/year was modelled and evaluated using a cradle-to-gate life cycle assessment approach. The sludge is a burden for pulp and paper mills that is mainly disposed in landfilling. The studied system allows for the valorisation of the waste, which due to its high polysaccharide content is a valuable feedstock for bioethanol production. Eleven impact categories were analysed and the results showed that enzymatic hydrolysis and neutralisation of the CaCO3 are the environmental hotspots of the system contributing up to 85% to the overall impacts. Two optimisation scenarios were evaluated: (1) using a reduced HCl amount in the neutralisation stage and (2) co-fermentation of xylose and glucose, for maximal ethanol yield. Both scenarios displayed significant environmental impact improvements.

Sacrum w drodze. Moskwa-Pietuszki Wieniedikta Jerofiejewa i Pulp Fiction Quentina Taranino w kluczu montażowego czytania

The aim of this monograph is the attempt of reading the poem Moscow-Petushki by Venedikt Erofeev and the film Pulp Fiction by Quentin Tarantino using the comparative approach, in which we go beyond the range of factual relationships, historical influences or similarities functioning in the structure of the presented world. The purpose of the book is to see both works of art from the angle of the montage theory of Sergei Eisenstein – the outstanding and highly regarded Russian director and film philosopher – which means studying cultural phenomena in their mutual intertextual relationships. The book focuses on the interpretation of the selected Tarantino’s and Erofeev’s texts of culture, in which the subject of the city, the search for the concept of the body at the end of 20th century and the problem of addictions constitute the dominant thematic issues. The monograph also offers the insight into the nature of the phenomenon of postmodernism and treats Eisenstein’s philosophy as the specific type of anticipation of postmodern tendencies in cinematography.

Kollektivtrafik som transformativ kraft för levande och hållbara städer

Denna studie uppmärksammar kollektivtrafik som transformativ förändringskraft i städer. I studien talas om att se kollektivtrafik som ryggraden i hållbar mobilitet och en möjliggörare för förändring, med visionen att bygga en stad för människor. En levande och attraktiv stad där kollektivtrafik sätts in i ett större sammanhang för att underlätta människors vardag.  Sveriges tre största stadsregioner; Stockholm, Göteborg och Malmö har studerats. För att på ett djupare plan förstå dessa förändringsprocesser har även sju internationella jämförelsestudier tagits fram (Freiburg, Zürich, London, Paris, Singapore, Kapstaden och Buenos Aires), liksom en konceptuell och teoretisk analys- och tolkningsram. Såväl de svenska som utländska fallstudierna pekar på att det finns många utmaningar i växande stadsregioner.  Studien ger en ökad insikt om att kollektivtrafik kan vara ett verktyg att bryta sociala och miljömässiga utmaningar, liksom mobilitetsutmaningar. Det krävs en avancerad produktionslogik för att utveckla kapacitetsstarka kollektivtrafiklösningar, men när allt är på plats i ett samverkande system kan kunden/resenären utnyttja systemet i sin egen värdeskapande process utifrån en kundorienterad tjänstelogik. Det finns ett behov av en fortsatt lärprocess för att använda kollektivtrafik som transformativ kraft. Det är människor som rör sig i staden, kollektivtrafik är endast ett medel. Det är med gemensamma offentliga och privata resurser som en levande, hållbar och attraktiv livsmiljö kan skapas, men det måste ske inom ramen gemensamma värderingar och berättelser.  Då utvecklas ett samhälle som bygger på tillit. Att hantera transformation, värdeskapande och hållberhet kräver flernivåstyrning, resursintegration och en utmaningsdriven tjänsteinnovation. Delarna finns där, men det behövs ett mer samlat grepp för att fullt ut utnyttja potentialen i Kollektivtrafik som transformativ kraft för levande och hållbara städer.

Quantification of free auxins in semi-hardwood plant cuttings and microshoots by dispersive liquid–liquid microextraction/microwave derivatization and GC/MS analysis

Several studies have suggested that differences in the natural rooting ability of plant cuttings could be attributed to differences in endogenous auxin levels. Hence, during rooting experiments, it is important to be able to routinely monitor the evolution of endogenous levels of plant hormones. This work reports the development of a new method for the quantification of free auxins in auxin-treated Olea europaea (L.) explants, using dispersive liquid–liquid microextraction (DLLME) and microwave assisted derivatization (MAD) followed by gas chromatography/mass spectrometry (GC/MS) analysis. Linear ranges of 0.5–500 ng mL 1 and 1–500 mg mL 1 were used for the quantification of indole-3-acetic acid (IAA) and indole-3-butyric acid (IBA), respectively. Determined by serial dilutions, the limits of detection (LOD) and quantification (LOQ) were 0.05 ng mL 1 and 0.25 ng mL 1, respectively for both compounds. When using the calibration curve for determination, the LOQ corresponded to 0.5 ng mL 1 (IAA) and 0.5 mg mL 1 (IBA). The proposed method proved to be substantially faster than other alternatives, and allowed free auxin quantification in real samples of semi-hardwood cuttings and microshoots of two olive cultivars. The concentrations found in the analyzed samples are in the range of 0.131–0.342 mg g 1 (IAA) and 20–264 mg g 1 (IBA).

Physicochemical and microbial analysis of feces from horses fed diets containing citrus pulp.

This study aimed to evaluate the e ect of diets containing increasing levels of citrus pulp on the physic-chemical and microbiological characteristics of horses feces. Five mares, at an average age of 3.5 years old and body weight of 492 ± 44.5 kg were arranged in a 5 x 5 Latin Square. The experimental diet consisted of 60% coast-cross hay and 40 % of concentrate with increasing levels of citrus pulp (0, 7, 14, 21, and 28 %). To determine the fecal pH, samples were collected directly from the oor, immediately after defecation, in the rst feces the day at 07:00 a.m., and color and fecal consistency were evaluated. For microbiological analysis, an aliquot was reserved in plastic bags, frozen, and sent to the microbiological laboratory for further analysis. Lactic acid bacteria were counted for Lactobacillus spp. and Streptococcus spp. from fecal samples under anaerobic conditions. The diet produced di erences (P<0.05) in feces consistency 98% had normal and rm stools, while 2% had loose ruminant-type feces. We observed no di erence (P<0.05) for color, verifying 100% of greenish feces, normal for equines. There was no e ect (P>0.05) on pH and on the number of Lactobacillus spp. and Streptococcus spp. The inclusion of up to 28% citrus pulp concentrates for horses did not promote change in the physio-chemical characteristics and on the population of lactic acid-producing bacteria in feces.
