Olen maa johon tahdot : Timo K. Mukan maailmankuvan poetiikkaa

The dissertation deals with the prose texts of the Finnish writer Timo K. Mukka, renowned for his depictions of his native Lapland. This research concerns the creation of world view in Mukka s prose, which is approached by studying what Mikhail Bakhtin calls generic change. Such genre change is the most characteristic feature of Mukka s prose. His prose is permeated with two genres in particular and changes between them: the ballad-like, archaistic and romantic prose-poem style and naturalistic, even grotesque expressions. In addition, these genres are associated with sublime and grotesque styles so that generic change tends to involve also stylistic changes in Mukka s prose. This study probes the tension-filled interrelationships between the ballad and naturalistic prose by examining the discourse of Mukka s characters. It is shown that these characters invariably find themselves in what Bakhtin calls the chronotope of the threshold; that is, the plots of Mukka s novels and short stories depict situations in which the characters are faced with decisions and deeds that will profoundly impact their lives. The discourse of the threshold affects the characters speech by filling it with dialogical dimensions. This makes their communication ethically loaded and polyphonic. This study is based on Mikhail Bakhtin s theory of the novel and international Bakhtin s studies. I also take into consideration the theoretical developments of Bakhtin s work; for example, the concept of ressentiment, adapted from the Bakhtin scholar Michel André Bernstein, plays an important role. In order to explicate on the psychology of Mukka s characters such as melancholy, abjection, sadism, and taboo I use the concepts familiar from Freudian psychoanalysis. The corpus of my research consists of the following texts: the long prose texts Maa on syntinen laulu. Balladi (1964), Tabu (1965), Täältä jostakin. Romaani (1965), Laulu Sipirjan lapsista. Romaani (1966), Ja kesän heinä kuolee. Kertomus sairaudesta (1968) ja Kyyhky ja unikko (1970) and the short story collections Koiran kuolema (1967) ja Lumen pelko (1970), and with Tabu published short story Sankarihymni , the short story Katkelma laajemmasta laulelmasta from the collection Rakastaa: Kaksitoista novellia rakkaudesta (1965) and also the short stories which were published in various Finnish journals: Yöt (1965), Liisa (1967), Tyttö (1967) ja Näin hetki sitten ketun (1970). I pay particular attention to the novel Maa on syntinen laulu, because it expresses the generic change characteristic of Mukka s world view in a specifically clear and lively way. The dissertation is in Finnish. Key words: Timo K.

Yhden äänen muotokuvia : Queer-luentoja Marguerite Yourcenarin teoksista

The present dissertation belongs to the tradition of queer theoretical and feminist literary scholarship. The study deals with the literary works of Marguerite Yourcenar (1903-1987), who was the first woman ever to be elected to the French Academy. The study seeks to lead an acclaimed classical French author into a dialogue with the characteristically Anglo-American queer theory and American tradition of queering Lacanian psychoanalysis. Queering the psychoanalytic notions of homosexuality and the categories of perversion and pervert will be elaborated in the present study. The main corpus of the scrutiny consists of five pieces of fiction written in French by Yourcenar. The first person narration and especially récit genre maintain a narrative strategy that the study explores with reference to the representations of non-normative genders and sexualities. Analyzing various radically queer aspects of Yourcenar's texts, the study focuses on the topical questions of masculinity in men, women, and texts. The study also discusses the representations of sexual desire between men, and the various constructions of male homosexuality in Yourcenar's fiction. The present study addresses Yourcenar's fiction from the points of view of female masculinity and textual female masculinity. The investigation finds its study questions and methodology in the area of queer studies, especially queer theoretical literary scholarship and the queer history and historiography of sexuality. That is why the study approaches Yourcenar's fiction in the context of historical and literary representations of male homosexual love and desire. The articulation of the closet, or textual and discursive strategies of sexual secrecy especially concerning male homosexuality, is simultaneously constructed and deconstructed in Yourcenar's fiction, as the analysis indicates. The study analyzes the Yourcenarian queer textual strategies with reference to concepts such as the epistemology and rhetoric of the closet, and the structure of the open secret as a part of the rhetoric of queer or non-straight sexuality. The present investigation puts the queer, non-normative representations of gender and sexuality in the centre of the Yourcenarian oeuvre and studies, ascertaining the strong bond between Yourcenar's work and the history, tradition, and the modern strategies of representing male homosexuality and queerness.

Betydelser i barnfamiljsbroschyrer : Systemisk-funktionell analys av den tänkta läsaren och institutionen

This thesis concerns Swedish and Finland-Swedish brochures to families with children, presenting family allowances from the social insurance institutions in the two countries. The aim of the study is to analyse what meanings are conveyed with reference to the conceivable reader and the institution in the brochures. The material consists of information brochures in Swedish from Kela, the social insurance institution of Finland, and Försäkringskassan, the Swedish social insurance agency, issued during 2003–2006. The general theoretical framework is systemic-functional linguistics (SFL) as presented by Halliday & Matthiessen (2004) and Holmberg & Karlsson (2006). The study consists of a quantitative study of the lexical choices of the social insurance brochures. Furthermore, a qualitative process and participant analysis is annotated with the UAM Corpus tool and the results are quantified. Speech functions and modal auxiliaries are analysed qualitatively. The analysis shows that material and relational processes are most common. The relational and verbal processes are used more in the Sweden-Swedish brochures, while the material processes are more common in the Finland-Swedish brochures. The participants in the brochures are the institution, mentioned by its name, and the conceivable reader, directly addressed with “you” (du). In addition, the referent “child” is often mentioned. The participants assigned for the reader are Actor, Receiver, Carrier and Speaker. In the Finland-Swedish texts, the reader is often an Actor, while the reader in the Sweden-Swedish texts is a Carrier. Thus, the conceivable reader is an active participant who takes care of his or her own matters using the internet, communicates actively to the institution and has legal rights and obligations. The institution is visible in the texts but does not have an active role as the name of the institution is mostly used in circumstances. The institution is not often a participant, but when it is, it is Actor, Receiver, Listener and Carrier, expecting the clients to address it. Speech functions are performed in different ways. For instance, questions structure the reading process and commands are realised by modal auxiliaries, not by imperatives. The most common modal auxiliary is kan (can, may), and another common auxiliary is ska (shall, must). Statements are surrounded by subordinate clauses and adverbs that describe situations and criteria. The results of the study suggest that the brochures in the two countries are similar, in particular when produced in similar ways, that is, when the Finland-Swedish texts are not translated. Existing differences reflect the differences in the institutions, the social insurance systems and the cultural contexts. KEYWORDS: Finland-Swedish, Swedish, comparative analysis, SFL, discourse analysis, administrative language, institutional discourse, institutional communication

Konstruktioner och valens : Verbfraser med åt i ett jämförande perspektiv

Det har knappast undgått någon som är språkligt medveten att finlandssvenskan och sverigesvenskan skiljer sig åt till vissa delar. Olikheterna återfinns på olika språkliga nivåer. Mest kända och omskrivna är de lexikologiska skillnaderna, dvs. skillnaderna på ordplanet. Betydligt mindre uppmärksamhet har ägnats syntaktiska skillnader, dvs. skillnader i hur satser och meningar byggs upp. För att öka kunskapen om finlandssvensk syntax initierade Språkvetenskapliga nämnden vid Svenska litteratursällskapet i Finland projektet Svenskan i Finland – syntaktiska drag i ett jämförande perspektiv, som pågick åren 2004–2006. Min avhandling har kommit till inom ramen för det projektet. Prepositionerna (t.ex. av, i, på, för, till, åt osv.) är så kallade funktionsord som har till uppgift att binda samman de mer betydelsetunga orden till satser och meningar. Den finlandssvenska prepositionsanvändningen skiljer sig i viss mån från den sverigesvenska, och ”åt” är en av de prepositioner som ofta lyfts fram som exempel. Finlandssvenskarna säger t.ex. ”han gav en bok åt Lena” i stället för ”han gav en bok till Lena” eller ”han gav Lena en bok”. De säger ”berätta något åt någon” (i stället för ”för”) och de säger ”ringa åt någon” i stället för ”ringa någon”. Ett huvudsyfte med min undersökning är att ta reda på hur pass stora skillnaderna är om man ser till samtliga belägg på ”åt” i ett material och inte bara till sådana som man fäster sig vid för att man vet att de avviker i finlandssvenskan. Undersökningen är korpusbaserad. Det betyder att jag letat efter alla belägg på kombinationer av verb och prepositionen ”åt” i rätt stora textmassor som finns tillgängliga i elektronisk form. Materialet ligger i Språkbanken i Finland och omfattar huvudsakligen tidningstext och skönlitteratur. Jag har använt mig av en textmassa på sammanlagt ungefär 40 miljoner löpande ord, drygt 23 miljoner finlandssvenska och drygt 19 miljoner sverigesvenska. Det materialet gav ca 20 000 åt-belägg att studera, och det visade sig något oväntat att ”åt” inte alls är vanligare i finlandssvenskan än i sverigesvenskan när det gäller skriftspråk, åtminstone inte i professionella skribenters språk. Om man kompenserar för att den finlandssvenska och den sverigesvenska korpusen inte är helt lika i fråga om genrefördelning och ålder, kommer man fram till i stort sett samma frekvens för ”åt” i båda korpusarna. För den närmare analysen av vilka mönster åt-beläggen uppvisar har jag först och främst utnyttjat konstruktionsgrammatik men också ramsemantik och valensteori. Konstruktionsgrammatiken är ingen enhetlig teori, men tanken om grammatiska konstruktioner är gemensam. Konstruktioner representerar allt från generella syntaktiska mönster till specifika mönster för språkliga enskildheter. Uppfattningen om vad som ska inbegripas i begreppet varierar, men definitionen av ”konstruktion” som ”par (eller konstellationer) av form och betydelse” är gemensam. ”Konstruktion” avser aldrig konkreta belägg i texter eller yttranden utan alltid det abstrakta mönstret bakom dessa. Och varje yttrande är resultatet av att en stor mängd konstruktioner samverkar. I min analys har jag utgått ifrån att beläggen med ”åt” kan återföras på olika konstruktioner eller mönster utifrån vad som är gemensamt för grupper av belägg. Jag har sett på vad åt-frasen i samverkan med verbet har för funktion i beläggen. En åt-fras är syntaktiskt en prepositionsfras och består av en preposition och en rektion. Exempelvis utgör ordparet ”åt skogen” en prepositionsfras där ”skogen” är rektion. Ur mitt material har jag kunnat abstrahera fram fem övergripande mönster där referenten för rektionen har olika så kallade semantiska roller. Åt-frasen kan i kombination med verbet ange mål eller riktmärke, som i t.ex. svänga åt höger, dra åt helvete, ta sig åt hjärtat, luta åt en seger för IFK. Den kan för det andra ange mottagare (t.ex. ge varsin kaka åt hundarna, bygga en bastu åt sina svärföräldrar, skaffa biljetter åt en kompis). För det tredje kan åt-frasen avse en referent som har nytta (eller skada) av en aktion (t.ex. klippa häcken åt grannen, ställa in digitalboxen åt sin moster). Åt-frasen kan slutligen avse den eller det som är föremål antingen för en kommunikationsaktion (vinka åt sin son, skratta åt eländet) eller en attityd eller känsla (glädja sig åt framgången). Utöver dessa huvudmönster finns det ett antal smärre grupper av belägg som bildar egna mönster, men de utgör sammanlagt under 3 % i bägge korpusarna. Inom grupperna kan undermönster urskiljas. I t.ex. mottagargruppen representerar ”ge varsin kaka åt hundarna” överföringskonstruktion, ”bygga en bastu åt sina svärföräldrar” produktionskonstruktion och ”skaffa biljetter åt en kompis” ombesörjningskonstruktion. Alla typer är gemensamma för bägge materialen, men andelen belägg som representerar de olika typerna skiljer sig betydligt. I det sverigesvenska materialet står t.ex. det mönster där åt-frasen avser mål eller riktmärke för en mycket större andel av beläggen än i finlandssvenskan. Också andelen belägg där åt-frasen avser någon som har nytta (eller skada) av en aktion är mycket högre i det sverigesvenska materialet. I det finlandssvenska materialet står i gengäld mottagarbeläggen för över 50 % av beläggen medan andelen i det sverigesvenska materialet är bara 30 %. Inom gruppen utgör belägg av produktions- och ombesörjningstyp dessutom en mindre andel i det finlandssvenska materialet än i det sverigesvenska. Dessa står till sin funktion nära den typ som avser den som har nytta av aktionen. De konkreta beläggen på överföring (ge varsin kaka åt hundarna) utgör en större andel i det finlandssvenska materialet än i det sverigesvenska (ca 8 % mot 3 %), men typiskt för båda materialen är hög kollokationsgrad (”kollokation” avser par eller grupper av ord som uppträder oftare tillsammans än de statiskt sett skulle göra vid helt slumpmässig förekomst). Största delen av mottagarbeläggen utgörs av fraser av typen ”ge arbete åt någon, ge eftertryck åt något, ge liv åt något; ägna tid åt något, ägna sitt liv åt något, ägna uppmärksamhet åt något”. De här slutsatserna gäller alltså skriftspråk. I talspråk ser fördelningen annorlunda ut. Typiskt för prepositionen ”åt” är överhuvudtaget hög kollokationsgrad. Det förefaller som om språkanvändarna har tydliga, färdiga mallar för var ”åt” kan komma in. Det enda mönster som verkar helt produktivt, i den meningen att elementen är i stort sett fritt kombinerbara, är kombinationer av verb och åt-fras där åt-frasen avser den som har nytta av något. Att någon utför något för någons räkning verkar överlag kunna uttryckas med prepositionen ”åt”: t.ex. ”tvätta bilen åt pappa, ringa efter en taxi åt kunden”. Till och med belägg av typen ”hon drömde åt honom att bli ordinarie adjunkt” förekommer i någon mån. Konstruktionen är produktiv i båda språkvarieteterna men uppenbart är att konstruktion med mottagare har tolkningsföreträde i vissa fall i finlandssvenskan: ”Filip skrev ett brev åt sin syster” tolkas av sverigesvenskar som att Filip skrev brevet för systerns räkning, medan finlandssvenskar överlag uppenbarligen tolkar det som att Filip skrev till sin syster, att systern var mottagare av brevet. Ungefär 20 % av alla belägg i båda materialen representerar fall där ”åt” utgör partikel. Verb och ”åt” är närmare förbundna med varandra än när ”åt” utgör normal preposition. Exempel på partikelbelägg är ”han kom inte åt strömbrytaren, det gick åt mängder med saft, landet får dra åt svångremmen, de roffade åt sig de bästa platserna”. Också partikelmaterialet ser på ett generellt plan väldigt lika ut i båda språkvarieteterna. Den största skillnaden uppvisar den reflexiva typen ”roffa åt sig”. Medan typen är mycket homogen i det sverigesvenska materialet är variationen större i det finlandsvenska. Dels uppträder fler verb i kombinationen (han köpte åt sig ett par jeans), dels vacklar ordföljden (han nappade åt sig ett paraply ~ han nappade ett paraply åt sig). Att ”åt” används mer i vissa funktioner i finlandsvenskan brukar förklaras med påverkan från finskans allativ (ändelsen -lle: hän antoi kirjan Astalle > hon gav en bok åt Asta). Allt tyder dock på att den finlandssvenska åt-användningen delvis är en relikt. I äldre sverigesvenska källor träffar man på ”åt” i sådana kontexter som numera är typiska för finlandsvenskan. Det finlandssvenska språkområdet ligger ute i periferin i relation till det språkliga centrum som förändringar sprider sig från (för svenskans del främst Stockholmstrakten) och typiskt för perifera områden är att de uppvisar ålderdomliga drag också när inga kontaktfenomen spelar in. Allativen kan naturligtvis ha bidragit till att bevara användningen av ”åt” i finlandssvenskan. Att det är just ”åt” som används” beror antagligen på att prepositionen har flest funktioner gemensamt med allativen rent kognitivt om man jämför med de betydligt mer frekventa prepositionerna ”till” och ”för”. Uppenbart är också att åt-användningen därtill lever sitt eget liv i finlandssvenskan. I vissa varieteter av finlandssvenska kan man t.ex. höra yttranden av typ ”alla fiskarna dog åt dom”. Som språklig enskildhet har det ingen finsk förebild med allativ. Yttrandet är ett exempel på töjning av en svensk konstruktion. Modell finns dels i det mönster där åt avser den som har nytta eller skada av något, dels i relationell användning av ”åt”: han är hantlangare åt Eriksson ~ han är Erikssons hantlangare. Vid språkkontakt är det överlag konstruktioner som har förebild i det låntagande språket som lånas in från det långivande språket, medan konstruktioner som saknar förebild är betydligt mindre benägna att vinna insteg.

Nonverbal predication in Erzya : Studies on morphosyntactic variation and part of speech distinctions

This dissertation consists of four articles and an introduction. The five parts address the same topic, nonverbal predication in Erzya, from different perspectives. The work is at the same time linguistic typology and Uralic studies. The findings based on a large corpus of empirical Erzya data, which was collected using several different methods and included recordings of the spoken language, made it possible for the present study to apply, then test and finally discuss the previous theories based on cross-linguistic data. Erzya makes use of multiple predication patterns which vary from totally analytic to the morphologically very complex. Nonverbal predicate clause types are classified on the basis of propositional acts in clauses denoting class-membership, identity, property and location. The predicates of these clauses are nouns, adjectives and locational expressions, respectively. The following three predication strategies in Erzya nonverbal predication can be identified: i. the zero-copula construction, ii. the predicative suffix construction and iii. the copula construction. It has been suggested that verbs and nouns cannot be clearly distinguished on morphological grounds when functioning as predicates in Erzya. This study shows that even though predicativity must not be considered a sufficient tool for defining parts of speech in any language, the Erzya lexical classes of adjective, noun and verb can be distinguished from each other also in predicate position. The relative frequency and degree of obligation for using the predicative suffix construction decreases when moving left to right on the scale verb adjective/locative noun ( identificational statement). The predicative suffix is the main pattern in the present tense over the whole domain of nonverbal predication in Standard Erzya, but if it is replaced it is most likely to be with a zero-copula construction in a nominal predication. This study exploits the theory of (a)symmetry for the first time in order to describe verbal vs. nonverbal predication. It is shown that the asymmetry of paradigms and constructions differentiates the lexical classes. Asymmetrical structures are motivated by functional level asymmetry. Variation in predication as such adds to the complexity of the grammar. When symmetric structures are employed, the functional complexity of grammar decreases, even though morphological complexity increases. The genre affects the employment of predication strategies in Erzya. There are differences in the relative frequency of the patterns, and some patterns are totally lacking from some of the data. The clearest difference is that the past tense predicative suffix construction occurs relatively frequently in Standard Erzya, while it occurs infrequently in the other data. Also, the predicative suffixes of the present tense are used more regularly in written Standard Erzya than in any other genre. The genre also affects the incidence of the translative in uľ(ń)ems copula constructions. In translations from Russian to Erzya the translative case is employed relatively frequently in comparison to other data. This study reveals differences between the two Mordvinic languages Erzya and Moksha. The predicative suffixes (bound person markers) of the present tense are used more regularly in Moksha in all kinds of nonverbal predicate clauses compared to Erzya. It should further be observed that identificational statements are encoded with a predicative suffix in Moksha, but seldom in Erzya. Erzya clauses are more frequently encoded using zero-constructions, displaying agreement in number only.

On Toponymic Constructions as an Alternative to Naming Patterns in Describing Finnish Lake Names

This thesis combines a computational analysis of a comprehensive corpus of Finnish lake names with a theoretical background in cognitive linguistics. The combination results on the one hand in a description of the toponymic system and the processes involved in analogy-based naming and on the other hand some adjustments to Construction Grammar. Finnish lake names are suitable for this kind of study, as they are to a large extent semantically transparent even when relatively old. There is also a large number of them, and they are comprehensively collected in a computer database. The current work starts with an exploratory computational analysis of co-location patterns between different lake names. Such an analysis makes it possible to assess the importance of analogy and patterns in naming. Prior research has suggested that analogy plays an important role, often also in cases where there are other motivations for the name, and the current study confirms this. However, it also appears that naming patterns are very fuzzy and that their nature is somewhat hard to define in an essentially structuralist tradition. In describing toponymic structure and the processes involved in naming, cognitive linguistics presents itself as a promising theoretical basis. The descriptive formalism of Construction Grammar seems especially well suited for the task. However, now productivity becomes a problem: it is not nearly as clear-cut as the latter theory often assumes, and this is even more apparent in names than in more traditional linguistic material. The varying degree of productivity is most naturally described by a prototype-based theory. Such an approach, however, requires some adjustments to onstruction Grammar. Based on all this, the thesis proposes a descriptive model where a new name -- or more generally, a new linguistic expression -- can be formed by conceptual integration from either a single prior example or a construction generalised from a number of different prior ones. The new model accounts nicely for various aspects of naming that are problematic for the traditional description based on analogy and patterns.

Päivä päivältä enemmän ja enemmän : Suomen toistokonstruktioita

Day by day more and more. Repetitive constructions in Finnish The study describes syntactic repetition in Finnish. Under investigation are short repetitive constructions in which the construction is connected by a morpheme, for example, päivä päivältä day by day , uudelleen ja uudelleen again and again . The study is a qualitative corpus-based study. It has three study questions. First, the study analyses the grammatical structure of repetitive constructions. Secondly, repetition is an iconic phenomenon, and the study investigates the motivation for repetition. Why and where is repetition used? Thirdly, the study will tentatively explain the syntactic productivity of the constructions. Syntactic repetition has semantic and pragmatic functions of which three are the most interesting. Firstly, it changes the aspectual interpretation of utterances. Durative situations become continuative, and semelfactive iterative. Secondly, repetition is also used to intensify expressions. Thirdly, repetition can be used to express superlative meanings. Repetition has many pragmatic functions. For example, it carries affective meanings in conversation. Repetition can also be used as an expressive tool in narrative contexts.

Determinants of vascular cognitive impairment : White matter lesions, brain atrophy and their neuropsychological correlates

The concept of vascular cognitive impairment (VCI) covers a wide spectrum of cognitive dysfunctions related to cerebrovascular disease. Among the pathophysiological determinants of VCI are cerebral stroke, white matter lesions and brain atrophy, which are known to be important risk factors for dementia. However, the specific mechanisms behind the brain abnormalities and cognitive decline are still poorly understood. The present study investigated the neuropsychological correlates of particular magnetic resonance imaging (MRI) findings, namely, medial temporal lobe atrophy (MTA), white matter hyperintensities (WMH), general cortical atrophy and corpus callosum (CC) atrophy in subjects with cerebrovascular disease. Furthermore, the cognitive profile of subcortical ischaemic vascular disease (SIVD) was examined. This study was conducted as part of two large multidisciplinary study projects, the Helsinki Stroke Aging Memory (SAM) Study and the multinational Leukoaraiosis and Disability (LADIS) Study. The SAM cohort consisted of 486 patients, between 55 and 85 years old, with ischaemic stroke from the Helsinki University Hospital, Helsinki, Finland. The LADIS Study included a mixed sample of subjects (n=639) with age-related WMH, between 65 and 84 years old, gathered from 11 centres around Europe. Both studies included comprehensive clinical and neuropsychological assessments and detailed brain MRI. The relationships between the MRI findings and the neuropsychological test performance were analysed by controlling for relevant confounding factors such as age, education and other coexisting brain lesions. The results revealed that in elderly patients with ischaemic stroke, moderate to severe MTA was specifically related to impairment of memory and visuospatial functions, but mild MTA had no clinical relevance. Instead, WMH were primarily associated with executive deficits and mental slowing. These deficits mediated the relationship between WMH and other, secondary cognitive deficits. Cognitive decline was best predicted by the overall degree of WMH, whereas the independent contribution of regional WMH measures was low. Executive deficits were the most prominent cognitive characteristic in SIVD. Compared to other stroke patients, the patients with SIVD also presented more severe memory deficits, which were related to MTA. The cognitive decline in SIVD occurred independently of depressive symptoms and, relative to healthy control subjects, it was substantial in severity. In stroke patients, general cortical atrophy also turned out to be a strong predictor of cognitive decline in a wide range of cognitive domains. Moreover, in elderly subjects with WMH, overall CC atrophy was related to reduction in mental speed, while anterior CC atrophy was independently associated with frontal lobe-mediated executive functions and attention. The present study provides cross-sectional evidence for the involvement of WMH, MTA, general cortical atrophy and CC atrophy in VCI. The results suggest that there are multifaceted pathophysiological mechanisms behind VCI in the elderly, including both vascular ischaemic lesions and neurodegenerative changes. The different pathological changes are highly interrelated processes and together they may produce cumulative effects on cognitive decline.

Genetics of heifer puberty in two tropical beef genotypes in northern Australia and associations with heifer- and steer-production traits

A total of 2115 heifers from two tropical genotypes (1007 Brahman and 1108 Tropical Composite) raised in four locations in northern Australia were ovarian-scanned every 4-6 weeks to determine the age at the first-observed corpus luteum (CL) and this was used to de. ne the age at puberty for each heifer. Other traits recorded at each time of ovarian scanning were liveweight, fat depths and body condition score. Reproductive tract size was measured close to the start of the first joining period. Results showed significant effects of location and birth month on the age at first CL and associated puberty traits. Genotypes did not differ significantly for the age or weight at first CL; however, Brahman were fatter at first CL and had a small reproductive tract size compared with that of Tropical Composite. Genetic analyses estimated the age at first CL to be moderately to highly heritable for Brahman (0.57) and Tropical Composite (0.52). The associated traits were also moderately heritable, except for reproductive tract size in Brahmans (0.03) and for Tropical Composite, the presence of an observed CL on the scanning day closest to the start of joining (0.07). Genetic correlations among puberty traits were mostly moderate to high and generally larger in magnitude for Brahman than for Tropical Composite. Genetic correlations between the age at CL and heifer- and steer-production traits showed important genotype differences. For Tropical Composite, the age at CL was negatively correlated with the heifer growth rate in their first postweaning wet season (-0.40) and carcass marbling score (-0.49), but was positively correlated with carcass P8 fat depth (0.43). For Brahman, the age at CL was moderately negatively genetically correlated with heifer measures of bodyweight, fatness, body condition score and IGF-I, in both their first postweaning wet and second dry seasons, but was positively correlated with the dry-season growth rate. For Brahman, genetic correlations between the age at CL and steer traits showed possible antagonisms with feedlot residual feed intake (-0.60) and meat colour (0.73). Selection can be used to change the heifer age at puberty in both genotypes, with few major antagonisms with steer- and heifer- production traits.

Integrating and evaluating neural word embeddings in information retrieval

Recent advances in neural language models have contributed new methods for learning distributed vector representations of words (also called word embeddings). Two such methods are the continuous bag-of-words model and the skipgram model. These methods have been shown to produce embeddings that capture higher order relationships between words that are highly effective in natural language processing tasks involving the use of word similarity and word analogy. Despite these promising results, there has been little analysis of the use of these word embeddings for retrieval. Motivated by these observations, in this paper, we set out to determine how these word embeddings can be used within a retrieval model and what the benefit might be. To this aim, we use neural word embeddings within the well known translation language model for information retrieval. This language model captures implicit semantic relations between the words in queries and those in relevant documents, thus producing more accurate estimations of document relevance. The word embeddings used to estimate neural language models produce translations that differ from previous translation language model approaches; differences that deliver improvements in retrieval effectiveness. The models are robust to choices made in building word embeddings and, even more so, our results show that embeddings do not even need to be produced from the same corpus being used for retrieval.

Susceptibility genes and neurodevelopmental mechanisms in dyslexia

Developmental dyslexia is a specific reading disability, which is characterised by unexpected difficulty in reading, spelling and writing despite adequate intelligence, education and social environment. It is the most common childhood learning disorder affecting 5-10 % of the population and thus constitutes the largest portion of all learning disorders. It is a persistent developmental failure although it can be improved by compensation. According to the most common theory, the deficit is in phonological processing, which is needed in reading when the words have to be divided into phonemes, or distinct sound elements. This occurs in the lowest level of the hierarchy of the language system and disturbs processes in higher levels, such as understanding the meaning of words. Dyslexia is a complex genetic disorder and previous studies have found nine locations in the genome that associate with it. Altogether four susceptibility genes have been found and this study describes the discovery of the first two of them, DYX1C1 and ROBO1. The first clues were obtained from two Finnish dyslexic families that have chromosomal translocations which disrupt these genes. Genetic analyses supported their role in dyslexia: DYX1C1 associates with dyslexia in the Finnish population and ROBO1 was linked to dyslexia in a large Finnish pedigree. In addition a genome-wide scan in Finnish dyslexic families was performed. This supported the previously detected dyslexia locus on chromosome 2 and revealed a new locus on chromosome 7. Dyslexia is a neurological disorder and the neurobiological function of the susceptibility genes DYX1C1 and ROBO1 are consistent with this. ROBO1 is an axon guidance receptor gene, which is involved in axon guidance across the midline in Drosophila and axonal pathfinding between the two hemispheres via the corpus callosum, as well as neuronal migration in the brain of mice. The translocation and decreased ROBO1 expression in dyslexic individuals indicate that two functional copies of ROBO1 gene are required in reading. DYX1C1 was a new gene without a previously known function. Inhibition of Dyx1c1 expression showed that it is needed in normal brain development in rats. Without Dyx1c1 protein, the neurons in the developing brain will not migrate to their final position in the cortex. These two dyslexia susceptibility genes DYX1C1 and ROBO1 revealed two distinct neurodevelopmental mechanisms of dyslexia, axonal pathfinding and neuronal migration. This study describes the discovery of the genes and our research to clarify their role in developmental dyslexia.

Identification of the Meckel syndrome gene (MKS1) exposes a novel ciliopathy

Meckel syndrome (MKS, MIM 249000) is an autosomal recessive developmental disorder causing death in utero or shortly after birth. The hallmarks of the disease are cystic kidney dysplasia and fibrotic changes of the liver, occipital encephalocele with or without hydrocephalus and polydactyly. Other anomalies frequently seen in the patients are incomplete development of the male genitalia, club feet and cleft lip or palate. The clinical picture has been well characterized in the literature while the molecular pathology underlying the disease has remained unclear until now. In this study we identified the first MKS gene by utilizing the disease haplotypes in Finnish MKS families linked to the MKS1 locus on chromosome 17q23 (MKS1) locus. Subsequently, the genetic heterogeneity of MKS was established in the Finnish families. Mutations in at least four different genes can cause MKS. These genes have been mapped to the chromosomes 17q23 (MKS1), 11q13 (MKS2), 8q22 (MKS3) and 9q33 (MKS4). Two of these genes have been identified so far: The MKS1 gene (this work) and the MKS3 gene. The identified MKS1 gene was initially a novel human gene which is conserved among species. We found three different MKS mutations, one of them being the Finnish founder mutation. The information available from MKS1 orthologs in other species convinced us that the MKS1 gene is required for normal ciliogenesis. Defects of the cilial system in other human diseases and model organisms actually cause phenotypic features similar to those seen in MKS patients. The MKS3 (TMEM67) gene encodes a transmembrane protein and the gene maps to the syntenic Wpk locus in the rat, which is a model with polycystic kidney disease, agenesis of the corpus callosum and hydrocephalus. The available information from these two genes suggest that MKS1 would encode a structural component of the centriole required for normal ciliary functions, and MKS3 would be a transmembrane component most likely required for normal ciliary sensory signaling. The MKS4 locus was localized to chromosme 9q32-33 in this study by using an inbred Finnish family with two affected and two healthy children. This fourth locus contains TRIM32 gene, which is associated to another well characterized human ciliopathy, Bardet Biedl syndrome (BBS). Future studies should identify the MKS4 gene on chromosome 9q and confirm if there are more than two genes causing MKS Finnish families. The research on critical signaling pathways in organogenesis have shown that both Wnt and Hedgehog pathways are dependent on functional cilia. The MKS gene products will serve as excellent model molecules for more detailed studies of the functional role of cilia in organogenesis in more detail.

Finding genes for economically important traits: Brahman cattle puberty.

Age at puberty is an important component of reproductive performance in beef cattle production systems. Brahman cattle are typically late-pubertal relative to Bos taurus cattle and so it is of economic relevance to select for early age at puberty. To assist selection and elucidate the genes underlying puberty, we performed a genome-wide association study (GWAS) using the BovineSNP50 chip (similar to 54 000 polymorphisms) in Brahman bulls (n = 1105) and heifers (n = 843) and where the heifers were previously analysed in a different study. In a new attempt to generate unbiased estimates of single-nucleotide polymorphism (SNP) effects and proportion of variance explained by each SNP, the available data were halved on the basis of year and month of birth into a calibration and validation set. The traits that defined age at puberty were, in heifers, the age at which the first corpus luteum was detected (AGECL, h(2) = 0.56 +/- 0.11) and in bulls, the age at a scrotal circumference of 26 cm (AGE26, h(2) = 0.78 +/- 0.10). At puberty, heifers were on average older (751 +/- 142 days) than bulls (555 +/- 101 days), but AGECL and AGE26 were genetically correlated (r = 0.20 +/- 0.10). There were 134 SNPs associated with AGECL and 146 SNPs associated with AGE26 (P < 0.0001). From these SNPs, 32 (similar to 22%) were associated (P < 0.0001) with both traits. These top 32 SNPs were all located on Chromosome BTA 14, between 21.95 Mb and 28.4 Mb. These results suggest that the genes located in that region of BTA 14 play a role in pubertal development in Brahman cattle. There are many annotated genes underlying this region of BTA 14 and these are the subject of current research. Further, we identified a region on Chromosome X where markers were associated (P < 1.00E-8) with AGE26, but not with AGECL. Information about specific genes and markers add value to our understanding of puberty and potentially contribute to genomic selection. Therefore, identifying these genes contributing to genetic variation in AGECL and AGE26 can assist with the selection for early onset of puberty.

Multi-trait assessment of early-in-life female, male and genomic measures for use in genetic selection to improve female reproductive performance of Brahman cattle

Early-in-life female and male measures with potential to be practical genetic indicators were chosen from earlier analyses and examined together with genomic measures for multi-trait use to improve female reproduction of Brahman cattle. Combinations of measures were evaluated on the genetic gains expected from selection of sires and dams for each of age at puberty (AGECL, i.e. first observation of a corpus luteum), lactation anoestrous interval in 3-year-old cows (LAI), and lifetime annual weaning rate (LAWR, i.e. the weaning rate of cows based on the number of annual matings they experienced over six possible matings). Selection was on an index of comparable records for each combination. Selection intensities were less than theoretically possible but assumed a concerted selection effort was able to be made across the Brahman breed. The results suggested that substantial genetic gains could be possible but need to be confirmed in other data. The estimated increase in LAWR in 10 years, for combinations without or with genomic measures, ranged from 8 to 12 calves weaned per 100 cows from selection of sires, and from 12 to 15 calves weaned per 100 cows from selection of sires and dams. Corresponding reductions in LAI were 60-103 days or 94-136 days, and those for AGECL were 95-125 or 141-176 days, respectively. Coat score (a measure of the sleekness or wooliness of the coat) and hip height in females, and preputial eversion and liveweight in males, were measures that may warrant wider recording for Brahman female reproduction genetic evaluation. Pregnancy-test outcomes from Matings 1 and 2 also should be recorded. Percentage normal sperm may be important to record for reducing LAI and scrotal size and serum insulin-like growth factor-I concentration in heifers at 18 months for reducing AGECL. Use of a genomic estimated breeding value (EBV) in combination with other measures added to genetic gains, especially at genomic EBV accuracies of 40%. Accuracies of genomic EBVs needed to approach 60% for the genomic EBV to be the most important contributor to gains in the combinations of measures studied.

Shaping urban consolidation debates: Social representations in Brisbane newspaper media

Recent international trends towards urban consolidation, intended to reduce outward urban sprawl by concentrating growth within existing neighbourhoods, can cause contention in cities. Understanding how the mass media represents urban consolidation can lead to more informed and democratic planning practices. This paper employs Social Representations Theory to identify and understand representations of urban consolidation in newspaper media. The theory recognises that the media is a key purveyor of public discourse and can reflect, shape or suppress ideas circulating in society. This novel approach has not previously been applied to understanding social representations of urban consolidation strategies in the mass media. The rapidly growing and changing city of Brisbane, Australia, is utilised as a case study. Brisbane is situated in South East Queensland, the fastest growing region in Australia, and is governed by regional and local planning policies that strongly support increased densities in existing urban areas. Findings from a quantitative textual analysis of 449 articles published in Brisbane newspapers between 2007 and 2014 reveal key clusters and classes of co-occurring words that represent dominant social representations apparent in the newspaper corpus. The paper provides two key conclusions. The first is that social representations occurring in mass media represent an important source of information about ‘common sense’ understandings and evaluations of urban consolidation debates. The second is that urban consolidation is represented as a ultifaceted issue, including interrelated themes of housing,sustainable population growth, investment strategies and the interplay between politics and planning
