Reforestation will have important consequences for the global challenges of mitigating climate change, arresting habitat decline and ensuring food security. We examined field-scale trade-offs between carbon sequestration of tree plantings and biodiversity potential and loss of agricultural land. Extensive surveys of reforestation across temperate and tropical Australia (N = 1491 plantings) were used to determine how planting width and species mix affect carbon sequestration during early development (< 15 year). Carbon accumulation per area increased significantly with decreasing planting width and with increasing proportion of eucalypts (the predominant over-storey genus). Highest biodiversity potential was achieved through block plantings (width > 40 m) with about 25% of planted individuals being eucalypts. Carbon and biodiversity goals were balanced in mixed-species plantings by establishing narrow belts (width < 20 m) with a high proportion (>75%) of eucalypts, and in monocultures of mallee eucalypt plantings by using the widest belts (ca. 6–20 m). Impacts on agriculture were minimized by planting narrow belts (ca. 4 m) of mallee eucalypt monocultures, which had the highest carbon sequestering efficiency. A plausible scenario where only 5% of highly-cleared areas (<30% native vegetation cover remaining) of temperate Australia are reforested showed substantial mitigation potential. Total carbon sequestration after 15 years was up to 25 Mt CO2-e year−1 when carbon and biodiversity goals were balanced and 13 Mt CO2-e year−1 if block plantings of highest biodiversity potential were established. Even when reforestation was restricted to marginal agricultural land (<$2000 ha−1 land value, 28% of the land under agriculture in Australia), total mitigation potential after 15 years was 17–26 Mt CO2-e year−1 using narrow belts of mallee plantings. This work provides guidance on land use to governments and planners. We show that the multiple benefits of young tree plantings can be balanced by manipulating planting width and species choice at establishment. In highly-cleared areas, such plantings can sequester substantial biomass carbon while improving biodiversity and causing negligible loss of agricultural land.

This paper describes how English as foreign language (EFL) teachers in Indonesia have implemented the recent character education policy within an era of school-based curriculum reform. The character education policy required all teachers, EFL teachers included, to instill certain values in every lesson whilst the school-based curriculum reform permitted teachers to develop locally responsive curriculum content. The design behind the reform seeks to sharpen education’s role as a site of moral inculcation in the face of growing social diversity that threatens social cohesion and the prolonged social problem of massive corruption. Drawing on Durkheim’s (1925) distinction between secular and religious morality, this paper considers how the Indonesian curriculum promoted rational or secular moral education and how the EFL teachers enacted religious moral education given religiosity is salient in both the community and schools of Indonesia. Bernstein’s concepts of pedagogic discourse, instructional and regulative discourses were adopted to analyse how EFL teachers have re-contextualized both curricular reforms in their micro pedagogic settings. The conclusion suggests that teachers’ implementation of moral education in their classes was dominated by their school communities’ and the teachers’ own preferred value of religiosity. Such values played out in their classes through both the regulative discourse and the instructional discourse.

Le Corbusier participated in an urban dialogue with the first group in France to call itself fascist: the journalist Georges Valois’s militant Faisceau des Combattants et Producteurs (1925-1927), the “Blue Shirts,” inspired by the Italian “Fasci” of Mussolini. Le Corbusier’s portrait photograph materialised on the front cover of the January 1927 issue of the Faisceau League’s newspaper Le Nouveau Siècle edited by the former anarcho-syndicalist journalist Georges Valois, its leader, who fashioned himself as the French Mussolini. Le Corbusier was described in the Revue as one of les animateurs (the “organisers”) of the Party1 – meaning a member of the technical elite who would drive the Faisceau’s plans. On 1 May 1927, the Nouveau Siècle printed a full-page feature “Le Plan Voisin” on Le Corbusier’s 1922 redesign of Paris : the architect’s single-point perspective sketch appeared below an extract lifted from the architect’s original polemic Le Centre de Paris on the pages of Le Corbusier’s second book Urbanisme published two years earlier, a treatise on urbanism.2 Three weeks later, Le Corbusier presented a slide show of his urban plans at a fascist rally for the inauguration of the Faisceau’s new headquarters on the rue du faubourg Poissonniere, thereby crystalising the architect’s hallowed status in the league...

Surfactant anion intercalated hydroxy salts of copper and cobalt of the formula M(OH)(2-x)(surf)(x)center dot mH(2)O [M = Cu, Co; surf = dodecyl sulfate. dodecyl benzene sulfonate. and x = 0.5 for Cu and 0.67 for Co] delaminate readily in 1-butanol to give translucent colloidal dispersions that are stable for months. The extent of delamination and the colloidal dispersion observed in these solids is higher than what had been observed for layered double hydroxides. The dispersions yield the corresponding nanoparticulate oxides on solvothermal decomposition. While the copper hydroxy salt forms similar to 300 nm dendrimer-like CuO nanostructures comprising nanorods of similar to 10 nm diameter, the cobalt analogue forms similar to 20 nm superparamagnetic particles of Co3O4.

The book presents a reconstruction, interpretation and critical evaluation of the Schumpeterian theoretical approach to socio-economic change. The analysis focuses on the problem of social evolution, on the interpretation of the innovation process and business cycles and, finally, on Schumpeter s optimistic neglect of ecological-environmental conditions as possible factors influencing social-economic change. The author investigates how the Schumpeterian approach describes the process of social and economic evolution, and how the logic of transformations is described, explained and understood in the Schumpeterian theory. The material of the study includes Schumpeter s works written after 1925, a related part of the commentary literature on these works, and a selected part of the related literature on the innovation process, technological transformations and the problem of long waves. Concerning the period after 1925, the Schumpeterian oeuvre is conceived and analysed as a more or less homogenous corpus of texts. The book is divided into 9 chapters. Chapters 1-2 describe the research problems and methods. Chapter 3 is an effort to provide a systematic reconstruction of Schumpeter's ideas concerning social and economic evolution. Chapters 4 and 5 focus their analysis on the innovation process. In Chapters 6 and 7 Schumpeter's theory of business cycles is examined. Chapter 8 evaluates Schumpeter's views concerning his relative neglect of ecological-environmental conditions as possible factors influencing social-economic change. Finally, chapter 9 draws the main conclusions.

Puu-Käpylä (“Wooden Käpylä”), a neighbourhood of Helsinki, is the earliest example of the Garden City Movement in Finland. The suburb of valuable wooden architecture was built between 1920 and 1925, with the aim to provide a healthy housing area for working-class families with many children. The houses were erected by a co-operative (Käpylän kansanasunnot, “People?s Dwellings”) and they are protected by the city plan since 1960?s. However, the historical value of the sheltered courtyards has not been investigated. The aim of this study was to survey the garden flora of Puu-Käpylä and to evaluate the authenticity of the courtyard gardens. The survey covered the area of one residential quarter (1.2 ha) with twelve 2-storey semi-detached timber houses arranged around a common yard, which was originally appointed for the tenants? vegetable gardens. The houses are still rented, and each flat is allowed a small lot of the courtyard for cultivation. A complete list was made of all perennial, ornamental plant taxa present in the quarter. Spring bulbs were missed due to the timing of the survey. Generally, the plants were recorded on species level, with the exception of common lilacs, shrub roses, irises and peonies that were thoroughly studied for cultivar identification. It was assumed that plants initially grown in the courtyard could be distinguished by studying Finnish garden magazines, books and nursery catalogues published in the 1920?s and by comparing the present vegetation to surviving documents from the quarter. The total number of ornamental plant taxa identified was 172, of which 17 were trees, 47 shrubs, 7 climbers and 101 herbaceous perennials. The results indicated that a major part of the shrubs, climbers and perennials presumably originated from the 1970?s or later, whereas ca. 70 % of the tree specimens were deemed as original. The survey disclosed a heritage variety of common lilac, resembling cultivar „Prince Notger?, a specific peony taxon, Paeonia humilis Retz., cultivated in Nordic countries since long ago, and a few historic iris varieties. Well-preserved design elements included front gardens on one side of the quarter, a maple alley on another side as well as trees at the garden gates. Old garden books and magazines did not shed much light on the Finnish garden flora commonly used in the period when Puu-Käpylä was built. However, they gave a valuable picture of contemporary planting design. Nursery catalogues offered insight into the assortment of ornamental plants traded in the 1920?s. Conclusions on the authenticity of the current flora were mainly drawn on the basis of old photographs and a vegetation survey map drawn in the 1970?s. This study revealed a need for standardization of syrvey methods applied when investigating garden floras. Uniform survey techniques would make the results comparable and enable a future compilation of data from e.g. historic gardens.

Tässä tutkimuksessa tutkittiin kanadalaisen kirjailijan L. M. Montgomeryn (1874 1942) elämää vuosina 1921 1927. Kyseisinä vuosina Montgomery eli presbyteeripapin vaimona maaseutuseurakunnissa, ensin Leaskdalessa ja sitten Norvalissa Kanadan Ontariossa. Tutkimus keskittyi tarkastelemaan kirjailijan elämää hallinnutta ristiriitaa, joka muodostui uskonnollisten ihanteiden ja yksilöllisen kokemuksen välisistä eroavaisuuksista. Primäärilähteinä olivat Montgomeryn toimitetut ja julkaistut päiväkirjat The Selected Journals of L. M. Montgomery 1 5 (1985 2004), joista käytettiin etenkin tutkimusvuosiin keskittyvää kolmatta osaa, Montgomeryn neljä romaania Emily of New Moon (1923), Emily Climbs (1925), Blue Castle (1926) ja Emily's Quest (1927) sekä Montgomeryn toimitettu ja julkaistu kirjeenvaihto After Green Gables: L. M. Montgomery's Letters to Ephraim Weber , 1916 1941 (2006) ja My Dear Mr. M.: Letters to G. B. MacMillan (1980). Lisäksi lähteinä oli Leaskdalen seurakuntalaisten kokoama muistelmateos Montgomerysta. Kirjallisuutta käytettiin kirkkohistorian, kirjallisuudentutkimuksen ja naistutkimuksen alalta. Suositusta kirjailijasta on tehty useampia elämäkertoja ja niitä hyödynnettiin tutkimuksessa. Tutkimus jakautui kahteen päälukuun, jotka toimivat toistensa vastaparina. Ensimmäinen tutkimusluku keskittyi tarkastelemaan uskonnollisia ja viktoriaanisia ihanteita, joiden mukaisesti Montgomery oli saanut kasvatuksen. Hän pyrki täyttämään näitä ihanteita myös pappilan emäntänä. Toinen tutkimusluku tarkasteli kirjailijan elämää, uskonnollisia ajatuksia ja avioliittoa julkisivun takana, jolloin kävi selvästi ilmi kirjailijan kahtiajakautunut elämä. Montgomery sai presbyteerisen ja viktoriaanisen kasvatuksen ja oppi jo lapsena huomioimaan sen, mitä muut ihmiset ajattelevat hänestä. Hän eli pienissä maaseutuyhteisöissä, joissa juoruilu oli yksi kontrollin väline. Papin vaimolla oli velvollisuuksia seurakunnassa ja pappilan hoidossa, ja Montgomery hoiti ne tarmokkaasti ja velvollisuudentuntoisesti. Hänellä oli apulainen pappilassa, jossa arki sujui viikkoaikataulun mukaisesti. Papin vaimon roolin lisäksi Montgomery jatkoi omaa kirjoittamistyötään ja hänen runsaat tulonsa mahdollistivat nelihenkisen perheen monet hankinnat. Hänen avioliittonsa oli vaikea, sillä aviomies kärsi uskonnollisesta melankoliasta ja asia piti salata seurakuntalaisilta. Montgomery käsittelee uskonnollisia teemoja romaaneissaan ja päiväkirjassaan. Hänen uskonnolliset ajatuksensa erosivat presbyteerikirkon opista useassa kohdin. Hän ei uskonut moneenkaan opinkappaleeseen, kohtasi Jumalan ennemmin luonnossa ollessaan yksin kuin kirkossa seurakunnan keskellä sekä ajatteli kristinuskon olevan jäännös menneestä ja tieteen ottaneen sen paikan Jumalan toiminnan kanavana. Kirjailijan ajattelussa on yhtymäkohtia transsendentalismiin, teosofiaan ja darwinismiin. Hän oli innokas psykologisen kirjallisuuden lukija ja sovelsi oppejaan käytäntöön. Hän uskoi unien välittävän viestejä. Kirkkokunta oli hänelle kuitenkin merkittävä identiteetin rakentaja. Papin vaimon roolin ja yksityisesti kriittisen ajattelijan roolin yhteensovittaminen aiheutti Montogmerylle ongelmia ja väsymystä. Hän kätki uskonnolliset ajatuksensa ja yksinäisyyden aiheuttaman kivun päiväkirjaansa, jonka hän toivoi julkaistavan viimeistään kuolemansa jälkeen. Kaikenlainen kirjoittaminen oli hänelle pakoa todellisuudesta ja auttoi häntä jaksamaan. Otsikon sitatti kuvaa Montgomeryn suhdetta kristinuskoon: hän käytti kristillisiä ilmauksia, mutta muokkasi niiden sisältöä omaa uskoaan vastaavaksi. Taivas ja helvetti kuvasivat usein hänen henkistä olotilaansa sanojen uskonnollisen merkityksen sijasta.

J.W. von Goethen (1749-1832) merkitys ei rajoitu saksalaisen kirjallisuuden uudistamiseen. Hänen keskeisin antinsa filosofialle on pikemminkin hänen kehittämässään luonnontieteellisessä tutkimusmetodissa ja siinä ilmenevässä organistisessa luonnonfilosofiassa. Myös Goethen taideteoreettisia käsityksiä on hedelmällistä tutkia hänen luonnonfilosofiansa näkökulmasta. Tarkastelen pro gradu-tutkielmassani Goethen luontokäsityksen ja taidekäsityksen kehitystä välittömästi hänen Italiaan suuntautuvia matkojaan 1786 1789 ympäröivänä ajanjaksona. Tähän aikaan sijoittuivat paitsi morfologisen tutkimusmetodin syntyminen, myös Goethen kuvataiteellisten ihanteiden yhä vahvempi kääntyminen antiikin esikuvien puoleen. Tutkin Goethen luonnontutkimusten taustalla olevan tietoteoreettisen asenteen muotoutumista suhteessa tulkintoihin, joita hän muodosti Benedict de Spinozan ja Immanuel Kantin filosofiasta. Jäljitän hänen näin muodostuneen luonnonfilosofisen näkemyksensä ilmenemistä hänen Weimarin klassismia edustaneissa taideteoreettisissa kirjoituksissaan. Kysymykseni on, onko Goethen kuvaamassa luonnontieteellisessä tutkimusmetodissa yhtymäkohtia siihen tiehen, jota taiteilijan tai taiteentuntijan on hänen mielestään kuljettava päästäkseen oikeaan käsitykseen taiteesta. Analysoidakseni tarkemmin taiteellisen ja tieteellisen toiminnan samankaltaisuutta Goethella vertailen keskenään 1789 julkaistua tekstiä Einfache Nachahmung der Natur, Manier, Stil (Luonnon yksinkertainen jäljittely, maneeri, tyyli), joka pohtii taiteen kuvaustavan suhdetta todellisuuteen, sekä lyhyttä luonnontieteellistä metodia kuvaavaa tekstiä Erfahrung und Wissenschaft (Kokemus ja tiede) vuodelta 1798. Asetan rinnakkain luonnontutkijan etenemisen empiirisestä ja tieteellisestä ilmiöstä puhtaaseen ilmiöön eli alkuilmiöön ja taiteellisen toiminnan jatkumon luonnon yksinkertaisesta jäljittelystä maneeriin ja tyyliin. Epilogissa hahmottelen Goethen metodin yhtymäkohtia moderniin fenomenologiaan sekä arvioin Rudolf Steinerin (1861 1925) Goethen tietoteoriasta tekemää tulkintaa.

Photographized nature I. K. Inha s work as a signification of nature The dissertation examines, through the work of the Finnish photographer and writer I. K. Inha (formerly Konrad Into Nyström) (1865 1930), the different ways in which the signification of nature is achieved. The principal material consists of Inha s work from 1890 to 1925, from which a number of photographs and texts are considered and upon which the photographization of nature is contemplated. The dissertation addresses the issue of how nature is conceived and how the act of photographizing it can be defined. The methodical context of the study is composed of three thematic baskets that structure the material and which consist of narrations on Finnish national perception, nature conservation and understanding the world. In the first case nature is seen as the natural environment encompassing lakes, seashores, forests, and hills, which at the time were often perceived from a utilitarian viewpoint. By the photographization they generated a pictorial narrative that could be shared. The natural environment was thus turned into landscape by means of photography, following the global pictorial concepts picturesque and sublime, as well as the national canons that had been developed in literature and the visual arts. In the narrations concerning nature conservation, the photographization did not merely occur within the limits of presuppositions, but rather nature was given the opportunity to unfold itself. While the photograph was being established as a basis for supporting nature conservation or to highlight the destruction of nature at the hand of Man, an attempt was made to represent subjects that were difficult to convey in photographs, such as nature s power or the miracle of growth. The thesis suggests, that in the third case the concept of nature broke away from its strict interconnection with the natural environment and led to a contemplation of nature that is perceivable in a person. In this context the photograph and the photographization are interpreted as an attempt to understand a person and his or her very existence in the world, while this same existential wonder is seen as being embodied in Inha s portrait of a rune singer and in his photographs of forest interior and water. Further, the thesis asks whether photographing nature could be interpreted as an action similar to the idea of the phenomenological reduction as a means of bypassing the photographer s prevailing way of being.
