Social media in selected Australian federal and state election campaigns, 2010-15

Campaigning in Australian election campaigns at local, state, and federal levels is fundamentally affected by the fact that voting is compulsory in Australia, with citizens who are found to have failed to cast their vote subject to fines. This means that - contrary to the situation in most other nations – elections are decided not by which candidate or party has managed to encourage the largest number of nominal supporters to make the effort to cast their vote, but by some 10-20% of genuine ‘swinging voters’ who change their party preferences from one election to the next. Political campaigning is thus aimed less at existing party supporters (so-called ‘rusted on’ voters whose continued support for the party is essentially taken for granted) than at this genuinely undecided middle of the electorate. Over the past decades, this has resulted in a comparatively timid, vague campaigning style from both major party blocs (the progressive Australian Labor Party [ALP] and the conservative Coalition of the Liberal and National Parties [L/NP]). Election commitments that run the risk of being seen as too partisan and ideological are avoided as they could scare away swinging voters, and recent elections have been fought as much (or more) on the basis of party leaders’ perceived personas as they have on stated policies, even though Australia uses a parliamentary system in which the Prime Minister and state Premiers are elected by their party room rather than directly by voters. At the same time, this perceived lack of distinctiveness in policies between the major parties has also enabled the emergence of new, smaller parties which (under Australia’s Westminster-derived political system) have no hope of gaining a parliamentary majority but could, in a close election, come to hold the balance of power and thus exert disproportionate influence on a government which relies on their support.

Studies of phosphazenes. Part 15. Chloro(phenoxy)cyclotetraphosphazenes, N4P4Cl8-n(OPh)n

The reaction of N4P4Cl8(1) with sodium phenoxide (or phenol in the presence of triethylamine) has been studied under a variety of experimental conditions. The chloro(phenoxy)-derivatives, N4P4Cl8-n(OPh)n[n= 1 or 2 (mixture of four non-geminal isomers), 3(mixture of non-geminal isomers), 4(mixture of isomers), 5(mixture of isomers), 6(mixture of four non-geminal isomers), or 8], have been isolated by column chromatography over silica gel. Attempts to separate geometric isomers were unsuccessful. Structural elucidation of the products is based on the 31P n.m.r. data for the chloro-precursors and 1H and 31P n.m.r. spectra of the dimethylamino- and/or methoxy-derivatives. The chlorine-replacement pattern is discussed.

Antibodies to guanosine: Fractionation and specificities

Bovine serum albumin conjugates of guanosine prepared by the periodate method was used as immunogen to elicit guanosine antibodies in rabbits. The specificities of the antibodies were studied by the inhibition of their binding to [3H]Gox-red, [32P]DNA and [3H]RNA by related non-radioactive compounds. A population of antibodies is specific to Gox-red with an average association constant of around 107M−1 at 4°C. There are a population of antibodies which bind to [32P]ssDNA and [3H]RNA specifically at guanosine residues. RNA binding antibodies were separated into two populations by affinity chromatography.

Imazhinist Mariengof : Dendi. Montazh. Ciniki.

The study is dedicated to the Russian poet and prose writer Anatolii Borisovich Mariengof (1897–1962). Mariengof – “the last dandy of the Republic” – was one of the leaders and main theoreticians in the poetic group of the Russian Imaginists. For his contemporaries, he was an Imaginist par excellence. His Imaginist principles – in theory and practice – are applied to the study of his first fictional novel, Cynics (1928), which served as an epilogue for his Imaginist period (1918–1928). The novel was not published in the Soviet Union until 1988. The method used in the study is a conceptual and literary historical reading, making use of the contemporary semiotic understanding of cultural mechanisms and of intertextual analysis. There are three main concepts used throughout the study: dandy, montage and catachresis. In the first chapter, the history, practice and theory of the Russian Imaginism are analyzed from the point of view of dandyism. The Imaginist theatricalisation of life is juxtaposed with the thematic analysis of their poetry, and Imaginist dandyism appears as a catachrestic category in culture. The second chapter examines the Imaginist poetic theory. It is discussed in the context of the montage principle, defining the post-revolutionary culture in Soviet Russia. The Imaginist montage can be divided into three main theoretical paradigms: S. Yesenin’s “technical montage” (reminiscent of Dadaist collage), V. Shershenevich’s “nominative montage” (catalogues of images) and Anatolii Mariengof’s “catachrestic montage”. The final chapter deals with Mariengof’s first fictional novel, Cynics. The study begins with the complex history of publication of the novel, as well as its relation to the Imaginist poetic principles and to the history of the poetic movement. Cynics is, essentially, an Imaginist montage novel. The fragmentary play of the fictional and the documentary material follows the Imaginist montage principle. The chapter concludes in a thematic analysis of the novel, concentrating on the description of the October Revolution in Cynics.

Utelämning i AV-översättning : En studie av textning i tre olika genrer

Tutkielman tavoitteena on kvalitatiivisen ja kvantitatiivisen analyysin avulla selvittää, millaisia poisjättöjä erityyppiset ohjelmat sisältävät. Tutkimusmateriaalina on lastenohjelma (Sune och hans värld), dokumentti (Yrke: kung) ja keskusteluohjelma (Bettina S) sekä niiden suomenkieliset tekstitykset. Jokaisesta ohjelmasta on analysoitu 15 minuuttia. Poisjättöjen luokittelussa pohjana on Koljosen (1995, 1997 ja 1998) luokittelu, joka koostuu kolmesta pääluokasta ja useasta alaluokasta. Kolme pääluokkaa ovat fakultatiiviset lauseenjäsenet (fakultativa satsdelar), puhekieliset piirteet (talspråkliga drag) ja informatiiviset osaset (informativa fragment). Hypoteeseja tutkielmassa on kaksi: suurin osa poisjätöistä on puhekielisyyksiä, mikä johtuu median vaihtumisesta puhutusta kirjoitettuun, ja informaatiota ei häviä, vaikka paljon on jätettävä pois aika- ja tilarajoitusten takia. Teoriaosassa käsitellään katsojan (tekstityksen vastaanottajan) tärkeää asemaa, poisjättöjen syitä ja poisjättöjä Koljosen luokittelun mukaisesti. Lisäksi teoriaosassa esitellään materiaalina olevat ohjelmatyypit, eli lastenohjelma, dokumentti ja puheohjelma. Analyysiosasta käy ilmi, että ohjelmat sisältävät melko erilaisia poisjättöjä. Tämä johtuu siitä, että lastenohjelmassa dialogi perustuu käsikirjoitukseen, kun taas dokumentissa ja keskusteluohjelmassa puhe on vapaata. Dokumentti on tyypillinen esimerkki monologista, eikä sisällä dialogille tyypillisiä piirteitä, kuten dialogipartikkeleita tai tervehdyksiä. Analyysistä käy myös ilmi, että valinnaisia lauseenjäseniä on jätetty eniten pois. Tämä johtuu ainoastaan siitä, että poisjätettyjen konjunktioiden määrä on suuri. Koljonen ei ole luokitellut konjunktioita tutkimuksissaan. Konjunktiot voitaisiin laskea myös diskurssipartikkeleihin (puhekielisiin piirteisiin), koska niillä on selvästi puhetta ohjaileva funktio, jolloin ensimmäinen hypoteeseista osoittautuisi todeksi. Puhekielisten piirteiden määrä vaihtelee ohjelmatyypistä riippuen. Dokumentti sisältää paljon toistoa, joka voidaan jättää pois. Keskusteluohjelmassa on puolestaan paljon poisjätettyjä dialogipartikkeleita, jotka toimivat vastauksena kysymykseen tai lyhyinä kommentteina. Lastenohjelmassa poisjättöjen jakauma on tasaisin: mikään ryhmä ei prosentuaalisesti erotu joukosta. Poisjätettyjen informaatiota sisältävien osasten määrä ei myöskään ole merkittävä. Analyysin perusteella voidaankin sanoa, että kummatkin hypoteesit osoittautuivat todeksi.

Encounters with the Virtual : The Experience of Art In Gilles Deleuze's Philosophy

My thesis concerns the notion of existence as an encounter, as developed in the philosophy of Gilles Deleuze (1925 1995). What this denotes is a critical stance towards a major current in Western philosophical tradition which Deleuze nominates as representational thinking. Such thinking strives to provide a stable ground for identities by appealing to transcendent structures behind the apparent reality and explaining the manifest diversity of the given by such notions as essence, idea, God, or totality of the world. In contrast to this, Deleuze states that abstractions such as these do not explain anything, but rather that they need to be explained. Yet, Deleuze does not appeal merely to the given. He sees that one must posit a genetic element that accounts for experience, and this element must not be naïvely traced from the empirical. Deleuze nominates his philosophy as transcendental empiricism and he seeks to bring together the approaches of both empiricism and transcendental philosophy. In chapter one I look into the motivations of Deleuze s transcendental empiricism and analyse it as an encounter between Deleuze s readings of David Hume and Immanuel Kant. This encounter regards, first of all, the question of subjectivity and results in a conception of identity as non-essential process. A pre-given concept of identity does not explain the nature of things, but the concept itself must be explained. From this point of view, the process of individualisation must become the central concern. In chapter two I discuss Deleuze s concept of the affect as the basis of identity and his affiliation with the theories of Gilbert Simondon and Jakob von Uexküll. From this basis develops a morphogenetic theory of individuation-as-process. In analysing such a process of individuation, the modal category of the virtual becomes of great value, being an open, indeterminate charge of potentiality. As the virtual concerns becoming or the continuous process of actualisation, then time, rather than space, will be the privileged field of consideration. Chapter three is devoted to the discussion of the temporal aspect of the virtual and difference-without-identity. The essentially temporal process of subjectification results in a conception of the subject as composition: an assemblage of heterogeneous elements. Therefore art and aesthetic experience is valued by Deleuze because they disclose the construct-like nature of subjectivity in the sensations they produce. Through the domain of the aesthetic the subject is immersed in the network of affectivity that is the material diversity of the world. Chapter four addresses a phenomenon displaying this diversified indentity: the simulacrum an identity that is not grounded in an essence. Developed on the basis of the simulacrum, a theory of identity as assemblage emerges in chapter five. As the problematic of simulacra concerns perhaps foremost the artistic presentation, I shall look into the identity of a work of art as assemblage. To take an example of a concrete artistic practice and to remain within the problematic of the simulacrum, I shall finally address the question of reproduction particularly in the case recorded music and its identity regarding the work of art. In conclusion, I propose that by overturning its initial representational schema, phonographic music addresses its own medium and turns it into an inscription of difference, exposing the listener to an encounter with the virtual.

On the Origin of Ideas : An Abductivist Approach to Discovery

The purpose of this study is to analyze and develop various forms of abduction as a means of conceptualizing processes of discovery. Abduction was originally presented by Charles S. Peirce (1839-1914) as a "weak", third main mode of inference -- besides deduction and induction -- one which, he proposed, is closely related to many kinds of cognitive processes, such as instincts, perception, practices and mediated activity in general. Both abduction and discovery are controversial issues in philosophy of science. It is often claimed that discovery cannot be a proper subject area for conceptual analysis and, accordingly, abduction cannot serve as a "logic of discovery". I argue, however, that abduction gives essential means for understanding processes of discovery although it cannot give rise to a manual or algorithm for making discoveries. In the first part of the study, I briefly present how the main trend in philosophy of science has, for a long time, been critical towards a systematic account of discovery. Various models have, however, been suggested. I outline a short history of abduction; first Peirce's evolving forms of his theory, and then later developments. Although abduction has not been a major area of research until quite recently, I review some critiques of it and look at the ways it has been analyzed, developed and used in various fields of research. Peirce's own writings and later developments, I argue, leave room for various subsequent interpretations of abduction. The second part of the study consists of six research articles. First I treat "classical" arguments against abduction as a logic of discovery. I show that by developing strategic aspects of abductive inference these arguments can be countered. Nowadays the term 'abduction' is often used as a synonym for the Inference to the Best Explanation (IBE) model. I argue, however, that it is useful to distinguish between IBE ("Harmanian abduction") and "Hansonian abduction"; the latter concentrating on analyzing processes of discovery. The distinctions between loveliness and likeliness, and between potential and actual explanations are more fruitful within Hansonian abduction. I clarify the nature of abduction by using Peirce's distinction between three areas of "semeiotic": grammar, critic, and methodeutic. Grammar (emphasizing "Firstnesses" and iconicity) and methodeutic (i.e., a processual approach) especially, give new means for understanding abduction. Peirce himself held a controversial view that new abductive ideas are products of an instinct and an inference at the same time. I maintain that it is beneficial to make a clear distinction between abductive inference and abductive instinct, on the basis of which both can be developed further. Besides these, I analyze abduction as a part of distributed cognition which emphasizes a long-term interaction with the material, social and cultural environment as a source for abductive ideas. This approach suggests a "trialogical" model in which inquirers are fundamentally connected both to other inquirers and to the objects of inquiry. As for the classical Meno paradox about discovery, I show that abduction provides more than one answer. As my main example of abductive methodology, I analyze the process of Ignaz Semmelweis' research on childbed fever. A central basis for abduction is the claim that discovery is not a sequence of events governed only by processes of chance. Abduction treats those processes which both constrain and instigate the search for new ideas; starting from the use of clues as a starting point for discovery, but continuing in considerations like elegance and 'loveliness'. The study then continues a Peircean-Hansonian research programme by developing abduction as a way of analyzing processes of discovery.

Makt, konst, elit - konstfältets positioner, relationer och resurser i 1940- och 1950-talens Helsingfors

The dissertation examines the power mechanisms and institutional power hierarchies of the 1940s-1950s era arts elite in Helsinki and their influence on issues of taste in the visual arts. For the purposes of this study, the elite is understood to consist mainly of the board members of the principal elected bodies in the field of the arts. The theoretical framework employed is based on Pierre Bourdieu s field theory and the network perspective. The author has examined what the key, pervasive valuations were that governed the exercising of power by the arts elite in issues of taste, involving determination of who was an acknowledged artist and what was good art. The dissertation demonstrates that this exercising of power was governed by certain collective practices which maintained the illusion that the exercising of power was democratic and based on artistic quality. These practices were the corporate system, using artistic arguments in issues of taste, and using networks in the exercising of power. The struggle in the field of the arts was about who ultimately was entitled to define the value of contemporary art; the issue did not arise regarding historical art. Artists managed to gain a leading position as gatekeepers in issues regarding contemporary art. The author discusses a number of conflicts in the field of the arts that highlight the institutional hierarchies and the capital held by the various players. The structural changes that occurred in administration in the field of cultural production in the 1950s led to the separation of bureaucratic competence on the one hand and aesthetic competence on the other. There was a hierarchy in the field of the arts between institutions, between instruments of legitimisation, and between the symbolic and social capital of players in the field. The hierarchy in the arts ultimately depended on how well the elite could influence tastes through the instruments at their disposal. The various instruments of legitimisation grants, purchases, etc. were ranked differently in the evaluation of acknowledged artists and good art. The dissertation discusses what values, in the form of types of symbolic capital, the arts elite embraced and what role these played in the elite s exercising of power, with particular focus on gender, language, region and economic capital. The aesthetic capital of an artist was of only minor importance in the exercising of power by the arts elite. The dissertation further discusses the points of contact between the arts elite and players in other fields, such as the economic, media and consumer fields. When the arts elite, through the Academy of Fine Arts, became an active player in the art market, this led to a hierarchy where the division between acknowledged and not-acknowledged galleries became sharper.

Maaseutuopistoista Yliopistoon : Maatalous- ja metsätieteiden tutkimus- ja opetustoiminnan akatemisoitumisprosessi Helsingin Yliopistossa vuoteen 1945

From Provincial Institutes to the University. The Academisation Process of the Research and Teaching of Agricultural and Forest Sciences at the University of Helsinki before 1945. This study focuses on the teaching and research conducted in the Faculty of Agriculture and Forestry at the University of Helsinki, as well as in its predecessor, the Section of Agriculture and Economics before 1945. The study falls into the field of university history. Its key research question is the academisation process, an example of which is the academisation process of the teaching and research of agricultural and forest sciences in Finland. From a perspective of university history, the study looks at academisation as the beginning of university-level teaching and research in these fields, or their relocation to a university or another institute of university standing. In addition to the above, the academisation process also includes the establishment of the position of the subjects and their acceptance as part of university activity. Academic closure, on the other hand, prevents the academisation of new subjects. In Finland, the preliminary stage of the academisation of the research and teaching of the agriculture and forestry was the Age of Utility, when questions concerning the subjects became part of clerical and civil service training at the Royal Academy of Turku in the mid-18th century. In the mid-19th century, as a result of social and economic development, agricultural and forestry professionals needed more theoretical professional training. At that time, the Imperial Alexander University was focused on traditional professional training and theoretical education, so, because of this academic closure, practical training for agronomists and foresters was organised at first outside the University at the Mustiala Agricultural Institute and the Evo Forest Institute. In the late 19th century, discussion began on the reform of higher agricultural and forestry education. This led, from the 1890s, to the academisation of higher agricultural and forestry education and research at the Alexander University. Academisation was followed by a transitional stage, during which the work of the Section of Agriculture and Economics, which had begun in 1902, became more established in about 1910. The position of the agricultural and forest sciences was, however, largely temporary, because of the planned Agricultural University. A sign of this establishment and of the rise in scientific status of the subjects was the commencement of operations of the Faculty of Agriculture and Forestry in 1924. Furthermore, as a consequence of the development of the subjects and the collapse of the Agricultural University project, agricultural and forest sciences gradually began to be accepted at the University of Helsinki from the end of the 1920s. This led to the allocation of sites for the faculty buildings and research farms, and to the building of ‘Metsätalo’ before the Second World War. Key words: academisation, academisation process, academic closure, university history, University of Helsinki, Faculty of Agriculture and Forestry, agricultural sciences, forest sciences, agronomy training, forestry training

Suomen Kuvalehden Hän-henkilöjutut tekstilajina

Tutkielma käsittelee Suomen Kuvalehden Hän-henkilöjuttuja tekstilajina. Lehti on itse nimennyt sarjan, mikä tukee ajatusta omasta tekstilajista. Marraskuusta 1989 lähtien Suomen Kuvalehdessä on ilmestynyt viikottain kahden aukeaman henkilöjuttu, jonka tekstin määrä ja jaottelu, otsikointi, taitto ja kuvitus ovat pysyneet lähes samana vuosien ajan. Jutut ovat pääosin tunnettujen suomalaisten haastatteluja. Hän-henkilöjutut ovat instituutio Suomen aikakauslehdistössä. Hän-henkilöjuttuja tarkastellaan tekstintutkimuksen keinoin. Teoreettisena viitekehyksenä on tekstilaji- eli genreteoria. Keskeiset teorialähteet ovat Swales (1990) ja Bhatia (1993). Työn aluksi Hän-henkilöjutut kontekstualisoidaan, mikä on olennaista tekstilajin tutkimisessa. Johdatuksessa perehdytään niin Hän-juttujen historiaan, Suomen Kuvalehden toimituksen näkemyksiin kuin journalistiikan oppikirjojen ohjeisiinkin. Hän-juttuja on ilmestynyt yli 700. Tutkimusaineisto rajataan pääosin vuoden 2003 juttuihin, mutta sarjan historiaa kerratessa juttuja tarkastellaan laajemmalti. Hän-logo, yhtenäiset otsikot ja tekstin asettelu ovat huomattavia tekstilajin määrittäjiä. Ne tekevät sarjaan toistuvuuden, jota vahvistetaan visuaalisesti. Hän-henkilöjuttujen valokuvia tarkastellaan Kressin ja van Leeuwenin visuaalisen kieliopin (1996) avulla. Kuvien säännönmukaisuus näkyy muun muassa niin, että vuoden 2003 Hän-juttujen kuvissa henkilö on useimmiten sijoitettu kuvan keskelle, ja tämä katsoo lähes poikkeuksetta suoraan kohti. Lisäksi henkilö on pienessä kuvassa rajattu tiukemmin kuin jutun pääkuvassa, joka täyttää 2/3 jutun ensimmäisestä aukeamasta. Kertojan havaittavuus tekstissä on omalaatuista Hän-henkilöjutuissa. Aihetta tarkastellaan käymällä tarkasti läpi yhden Hän-jutun koko kerronta. Taustalla on kirjallisuustieteen narratologian näkemys fyysisen tekijän ja kertojan eriävyydestä. Hän-henkilöjutussa Maskun Kalustetalon toimitusjohtajasta Toivo Sukarista (Suomen Kuvalehti 39/2003) havaitaan, että kertoja on jatkuvasti läsnä. Ainoastaan havaittavuuden aste vaihtelee. Kertoja esittää kysymyksiä, hän käskee lukijaa, huudahtaa, havainnoi kohdehenkilöä ja tapahtumaympäristöä, ottaa kantaa, esittää yhteenvetoja ja käyttää nimeämisen valtaa. Tuloksia kertojan havaittavuudesta testataan 15:een Hän-henkilöjuttuun. Niistä 12 on vuodelta 2003, lisäksi mukana on yksi juttu vuodelta 1990, 1995 ja 2000. Jutuista hahmotetaan tekstilajin kertojaa, joksi kirjallisuustieteen sisäistekijää kutsun. Tekstilajin kertojan rajoitukset ovat väljät, mutta havaittavuus näyttää olevan sidoksissa käsiteltävän henkilön tunnettuuteen. Mitä tunnetumpi henkilö, sitä enemmän kertoja voi tekstissä näyttäytyä. Lopuksi kartoitetaan Hän-henkilöjuttujen aloituksia. Niissä hahmottuu päätyyppejä, kuten tapahtuma-aloitus, havaintoaloitus ja referointialoitus, mutta tarkkarajaista luokittelua niistä ei voi tehdä. Osaksi sen perusteella voidaan väittää, että Hän-henkilöjutuilla ei ole kaavaa. Avainsanat: tekstintutkimus, tekstilaji, genre, henkilöjuttu, haastattelu, kertoja, sisäistekijä, aloitukset

Fatigued driving : prevalence, risk factors and groups, and the law

Fatigue and sleepiness are major causes of road traffic accidents. However, precise data is often lacking because a validated and reliable device for detecting the level of sleepiness (cf. the breathalyzer for alcohol levels) does not exist, nor does criteria for the unambiguous detection of fatigue/sleepiness as a contributing factor in accident causation. Therefore, identification of risk factors and groups might not always be easy. Furthermore, it is extremely difficult to incorporate fatigue in operationalized terms into either traffic or criminal law. The main aims of this thesis were to estimate the prevalence of fatigue problems while driving among the Finnish driving population, to explore how VALT multidisciplinary investigation teams, Finnish police, and courts recognize (and prosecute) fatigue in traffic, to identify risk factors and groups, and finally to explore the application of the Finnish Road Traffic Act (RTA), which explicitly forbids driving while tired in Article 63. Several different sources of data were used: a computerized database and the original folders of multidisciplinary teams investigating fatal accidents (VALT), the driver records database (AKE), prosecutor and court decisions, a survey of young male military conscripts, and a survey of a representative sample of the Finnish active driving population. The results show that 8-15% of fatal accidents during 1991-2001 were fatigue related, that every fifth Finnish driver has fallen asleep while driving at some point during his/her driving career, and that the Finnish police and courts punish on average one driver per day on the basis of fatigued driving (based on the data from the years 2004-2005). The main finding regarding risk factors and risk groups is that during the summer months, especially in the afternoon, the risk of falling asleep while driving is increased. Furthermore, the results indicate that those with a higher risk of falling asleep while driving are men in general, but especially young male drivers including military conscripts and the elderly during the afternoon hours and the summer in particular; professional drivers breaking the rules about duty and rest hours; and drivers with a tendency to fall asleep easily. A time-of-day pattern of sleep-related incidents was repeatedly found. It was found that VALT teams can be considered relatively reliable when assessing the role of fatigue and sleepiness in accident causation; thus, similar experts might be valuable in the court process as expert witnesses when fatigue or sleepiness are suspected to have a role in an accident’s origins. However, the application of Article 63 of the RTA that forbids, among other things, fatigued driving will continue to be an issue that deserves further attention. This should be done in the context of a needed attitude change towards driving while in a state of extreme tiredness (e.g., after being awake for more than 24 hours), which produces performance deterioration comparable to illegal intoxication (BAC around 0.1%). Regarding the well-known interactive effect of increased sleepiness and even small alcohol levels, the relatively high proportion (up to 14.5%) of Finnish drivers owning and using a breathalyzer raises some concern. This concern exists because these drivers are obviously more focused on not breaking the “magic” line of 0.05% BAC than being concerned about driving impairment, which might be much worse than they realize because of the interactive effects of increased sleepiness and even low alcohol consumption. In conclusion, there is no doubt that fatigue and sleepiness problems while driving are common among the Finnish driving population. While we wait for the invention of reliable devices for fatigue/sleepiness detection, we should invest more effort in raising public awareness about the dangerousness of fatigued driving and educate drivers about how to recognize and deal with fatigue and sleepiness when they ultimately occur.

Hydrothermal phase equilibria studies in Ln2O3---H2O systems and synthesis of cubic lanthanide oxides

Phase diagrams for the systems Ln2O3---H2O (Ln = La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Lu and Y) studied at 5000 to 10,000 psi and temperature range of 200–900°C, show that Ln(OH)3 hexagonal and LnOOH monoclinic are the only stable phases from Nd to Ho. The cubic oxide phase (C---Ln2O3) is stable for systems of Er, Tm, Yb and Lu, with no evidence of its equilibrium in the systems of lighter lanthanides. Using strong acids, HNO3 and HCOOH, as mineralisers the cubic oxides could be stabilised from Eu down to Lu. Solid solution phases of CeO2---Y2O3 and Eu2O3---Y2O3 have also been synthesised with HNO3 as mineraliser, since these compounds have promising use as solid electrolyte and phosphor materials respectively.

New annual and short-lived perennial pasture legumes for Australian agriculture--15 years of revolution

Fifteen years ago subterranean clover (Trifolium subterraneum) and annual medics (Medicago spp.) dominated annual pasture legume sowings in southern Australia, while limited pasture legume options existed for cropping areas of subtropical Australia. Since then a number of sustainability and economic challenges to existing farming systems have emerged, exposing shortcomings in these species and the lack of legume biodiversity. Public breeding institutions have responded to these challenges by developing 58 new annual and short-lived perennial pasture legumes with adaptation to both existing and new farming systems. This has involved commercialisation of new species and overcoming deficiencies in traditional species. Traits incorporated in legumes of Mediterranean Basin origin for the Mediterranean, temperate and southern subtropical climates of Australia include deeper root systems, protection from false breaks (germination-inducing rainfall events followed by death from drought), a range of hardseed levels, acid-soil tolerant root nodule symbioses, tolerance to pests and diseases and provision of lower cost seed through ease of seed harvesting and processing. Ten new species, French serradella (Ornithopus sativus), biserrula (Biserrula pelecinus), sulla (Hedysarum coronarium), gland (Trifolium glanduliferum), arrowleaf (Trifolium vesiculosum), eastern star (Trifolium dasyurum) and crimson (Trifolium incarnatum) clovers and sphere (Medicago sphaerocarpos), button (Medicago orbicularis) and hybrid disc (Medicago tornata x Medicago littoralis) medics have been commercialised. Improved cultivars have also been developed of subterranean (T. subterraneum), balansa (Trifolium michelianum), rose (Trifolium hirtum), Persian (Trifolium resupinatum) and purple (Trifolium purpureum) clovers, burr (Medicago polymorpha), strand (M. littoralis), snail (Medicago scutellata) and barrel (Medicago truncatula) medics and yellow serradella (Ornithopus compressus). New tropical legumes for pasture phases in subtropical cropping areas include butterfly pea (Clitoria ternatea), burgundy bean (Macroptilium bracteatum) and perennial lablab (Lablab purpureus). Other species and cultivars of Mediterranean species are likely to be released soon. The contributions of genetic resources, rhizobiology, pasture ecology and agronomy, plant pathology, entomology, plant chemistry and animal science have been paramount to this success. A farmer survey in Western Australia has shown widespread adoption of the new pasture legumes, while adoption of new tropical legumes has also been high in cropping areas of the subtropics. This trend is likely to increase due to the increasing cost of inorganic nitrogen, the need to combat herbicide-resistant crop weeds and improved livestock prices. Mixtures of these legumes allows for more robust pastures buffered against variable seasons, soils, pests, diseases and management decisions. This paper discusses development of the new pasture legumes, their potential use and deficiencies in the current suite.
