Creation of a new evaluation benchmark for information retrieval targeting patient information needs

Searching for health advice on the web is becoming increasingly common. Because of the great importance of this activity for patients and clinicians and the effect that incorrect information may have on health outcomes, it is critical to present relevant and valuable information to a searcher. Previous evaluation campaigns on health information retrieval (IR) have provided benchmarks that have been widely used to improve health IR and record these improvements. However, in general these benchmarks have targeted the specialised information needs of physicians and other healthcare workers. In this paper, we describe the development of a new collection for evaluation of effectiveness in IR seeking to satisfy the health information needs of patients. Our methodology features a novel way to create statements of patients’ information needs using realistic short queries associated with patient discharge summaries, which provide details of patient disorders. We adopt a scenario where the patient then creates a query to seek information relating to these disorders. Thus, discharge summaries provide us with a means to create contextually driven search statements, since they may include details on the stage of the disease, family history etc. The collection will be used for the first time as part of the ShARe/-CLEF 2013 eHealth Evaluation Lab, which focuses on natural language processing and IR for clinical care.

Overview of the ShARe/CLEF eHealth Evaluation Lab 2013

Discharge summaries and other free-text reports in healthcare transfer information between working shifts and geographic locations. Patients are likely to have difficulties in understanding their content, because of their medical jargon, non-standard abbreviations,and ward-specific idioms. This paper reports on an evaluation lab with an aim to support the continuum of care by developing methods and resources that make clinical reports in English easier to understand for patients, and which helps them in finding information related to their condition.

ShARe/CLEF eHealth Evaluation Lab 2013, Task 3: Information retrieval to address patients' questions when reading clinical reports

This paper presents the results of task 3 of the ShARe/CLEF eHealth Evaluation Lab 2013. This evaluation lab focuses on improving access to medical information on the web. The task objective was to investigate the effect of using additional information such as the discharge summaries and external resources such as medical ontologies on the IR effectiveness. The participants were allowed to submit up to seven runs, one mandatory run using no additional information or external resources, and three each using or not using discharge summaries.

Residual stresses in rail-ends from the in-service insulated rail joints using neutron diffraction

Insulated rail joints (IRJs) are an integral part of the rail track signaling system and pose significant maintenance and replacement costs due to their low and fluctuating service lives. Failure occurs mainly in rail head region, bolt- holes of fishplates and web-holes of the rails. Propagation of cracks is influenced by the evolution of internal residual stresses in rails during rail manufacturing (hot-rolling, roller-straightening, and head-hardening process), and during service, particularly in heavy rail haul freight systems where loads are high. In this investigation, rail head accumulated residual stresses were analysed using neutron diffraction at the Australian Nuclear Science and Technology Organisation (ANSTO). Two ex-service two head-hardened rail joints damaged under different loading were examined and results were compared with those obtained from an unused rail joint reference sample in order to differentiate the stresses developed during rail manufacturing and stresses accumulated during rail service. Neutron diffraction analyses were carried out on the samples in longitudinal, transverse and vertical directions, and on 5mm thick sliceed samples cut by Electric Discharge Machining (EDM). For the rail joints from the service line, irrespective of loading conditions and in-service times, results revealed similar depth profiles of stress distribution. Evolution of residual stress fields in rails due to service was also accompanied by evidence of larger material flow based on reflected light and scanning electron microscopy studies. Stress evolution in the vicinity of rail ends was characterised by a compressive layer, approximately 5 mm deep, and a tension zone located approximately 5- 15mm below the surfaces. A significant variation of d0 with depth near the top surface was detected and was attributed to decarburization in the top layer induced by cold work. Stress distributions observed in longitudinal slices of the two different deformed rail samples were found to be similar. For the undeformed rail, the stress distributions obtained could be attributed to variations associated with thermo-mechanical history of the rail.

Fault detection of slow speed rolling element bearing with noise removal techniques

Rolling Element Bearings (REBs) are vital components in rotating machineries for providing rotating motion. In slow speed rotating machines, bearings are normally subjected to heavy static loads and a catastrophic failure can cause enormous disruption to production and human safety. Due to its low operating speed the impact energy generated by the rotating elements on the defective components is not sufficient to produce a detectable vibration response. This is further aggravated by the inability of general measuring instruments to detect and process the weak signals at the initiation of the defect accurately. Furthermore, the weak signals are often corrupted by background noise. This is a serious problem faced by maintenance engineers today and the inability to detect an incipient failure of the machine can significantly increases the risk of functional failure and costly downtime. This paper presents the application of noise removal techniques for enhancing the detection capability for slow speed REB condition monitoring. Blind deconvolution (BD) and adaptive line enhancer (ALE) are compared to evaluate their performance in enhancing the source signal with consequential removal of background noise. In the experimental study, incipient defects were seeded on a number of roller bearings and the signals were acquired using acoustic emission (AE) sensor. Kurtosis and modified peak ratio (mPR) were used to determine the detectability of signal corrupted by noise.

Endurance test-rig for diagnostics and prognostics of rolling element bearings

Detection of faults in roller element bearing is a topic widely discussed in the scientific field. Bearings diagnostics is usually performed by analyzing experimental signals, almost always vibration signals, measured during operation. A number of signal processing techniques have been proposed and applied to measured vibrations. The diagnostic effectiveness of the techniques depends on their capacities and on the environmental conditions (i.e. environmental noise). The current trend, especially from an industrial point of view, is to couple the prognostics to the diagnostics. The realization of a prognostic procedure require the definition of parameters able to describe the bearing condition during its operation. Monitoring the values of these parameters during time allows to define their trends depending on the progress of the wear. In this way, a relation between the variation of the selected parameters and the wear progress, useful for diagnostics and prognostics of bearings in real industrial applications, can be established. In this paper, a laboratory test-rig designed to perform endurance tests on roller element bearing is presented. Since the test-rig has operated for a short time, only some preliminary available results are discussed.

An experimental based assessment of the deviation of the bearing characteristic frequencies

Slippage in the contact roller-races has always played a central role in the field of diagnostics of rolling element bearings. Due to this phenomenon, vibrations triggered by a localized damage are not strictly periodic and therefore not detectable by means of common spectral functions as power spectral density or discrete Fourier transform. Due to the strong second order cyclostationary component, characterizing these signals, techniques such as cyclic coherence, its integrated form and square envelope spectrum have proven to be effective in a wide range of applications. An expert user can easily identify a damage and its location within the bearing components by looking for particular patterns of peaks in the output of the selected cyclostationary tool. These peaks will be found in the neighborhood of specific frequencies, that can be calculated in advance as functions of the geometrical features of the bearing itself. Unfortunately the non-periodicity of the vibration signal is not the only consequence of the slippage: often it also involves a displacement of the damage characteristic peaks from the theoretically expected frequencies. This issue becomes particularly important in the attempt to develop highly automated algorithms for bearing damage recognition, and, in order to correctly set thresholds and tolerances, a quantitative description of the magnitude of the above mentioned deviations is needed. This paper is aimed at identifying the dependency of the deviations on the different operating conditions. This has been possible thanks to an extended experimental activity performed on a full scale bearing test rig, able to reproduce realistically the operating and environmental conditions typical of an industrial high power electric motor and gearbox. The importance of load will be investigated in detail for different bearing damages. Finally some guidelines on how to cope with such deviations will be given, accordingly to the expertise obtained in the experimental activity.

Tuning second order cyclostationarity parameters for the diagnostics of rolling element bearings

Failures on rolling element bearings usually originate from cracks that are detectable even in their early stage of propogation by properly analyzing vibration signals measured in the proximity of the bearing. Due to micro-slipping in the roller-races contact, damage-induced vibration signals belong to the family of quasi-periodic signals with a strong second order cyclostationary component. Cyclic coherence and its integrated form are widely considered as the most suitable tools for bearing fault diagnostics and their theoretical bases have been already consolidated. This paper presents how to correctly set the parameters of the cyclostationary analysis tool to be implemented in an automatable algorithm. In the first part of the paper some general guidelines are provided for the specific application. These considerations are further verified, applying cyclostationary tools to data collected in an experimental campaign on a specific test-rig.

Measuring, modelling and understanding the mechanical behavior of bagasse

In the Australian sugar industry, sugar cane is smashed into a straw like material by hammers before being squeezed between large rollers to extract the sugar juice. The straw like material is initially called prepared cane and then bagasse as it passes through successive roller milling units. The sugar cane materials are highly compressible, have high moisture content, are fibrous, and they resemble some peat soils in both appearance and mechanical behaviour. A promising avenue to improve the performance of milling units for increased throughput and juice extraction, and to reduce costs is by modelling of the crushing process. To achieve this, it is believed necessary that milling models should be able to reproduce measured bagasse behaviour. This investigation sought to measure the mechanical (compression, shear, and volume) behaviour of prepared cane and bagasse, to identify limitations in currently used material models, and to progress towards a material model that can predict bagasse behaviour adequately. Tests were carried out using a modified direct shear test equipment and procedure at most of the large range of pressures occurring in the crushing process. The investigation included an assessment of the performance of the direct shear test for measuring bagasse behaviour. The assessment was carried out using finite element modelling. It was shown that prepared cane and bagasse exhibited critical state behavior similar to that of soils and the magnitudes of material parameters were determined. The measurements were used to identify desirable features for a bagasse material model. It was shown that currently used material models had major limitations for reproducing bagasse behaviour. A model from the soil mechanics literature was modified and shown to achieve improved reproduction while using magnitudes of material parameters that better reflected the measured values. Finally, a typical three roller mill pressure feeder configuration was modelled. The predictions and limitations were assessed by comparison to measured data from a sugar factory.

Design and test of a custom instrumented leg press for injury and recovery intervention

There is an increasing desire and emphasis to integrate assessment tools into the everyday training environment of athletes. These tools are intended to fine-tune athlete development, enhance performance and aid in the development of individualised programmes for athletes. The areas of workload monitoring, skill development and injury assessment are expected to benefit from such tools. This paper describes the development of an instrumented leg press and its application to testing leg dominance with a cohort of athletes. The developed instrumented leg press is a 45° reclining sled-type leg press with dual force plates, a displacement sensor and a CCD camera. A custom software client was developed using C#. The software client enabled near-real-time display of forces beneath each limb together with displacement of the quad track roller system and video feedback of the exercise. In recording mode, the collection of athlete particulars is prompted at the start of the exercise, and pre-set thresholds are used subsequently to separate the data into epochs from each exercise repetition. The leg press was evaluated in a controlled study of a cohort of physically active adults who performed a series of leg press exercises. The leg press exercises were undertaken at a set cadence with nominal applied loads of 50%, 100% and 150% of body weight without feedback. A significant asymmetry in loading of the limbs was observed in healthy adults during both the eccentric and concentric phases of the leg press exercise (P < .05). Mean forces were significantly higher beneath the non-dominant limb (4–10%) and during the concentric phase of the muscle action (5%). Given that symmetrical loading is often emphasized during strength training and remains a common goal in sports rehabilitation, these findings highlight the clinical potential for this instrumented leg press system to monitor symmetry in lower-limb loading during progressive strength training and sports rehabilitation protocols.

Gustaf III inför sina undersåtar : Konsten att härska och politikens kulturhistoria

The dissertation analyses the political culture of Sweden during the reign of King Gustav III (1771-1792). This period commonly referred to as the Gustavian era followed the so-called Age of Liberty ending half a century of strong parliamentary rule in Sweden. The question at the heart of this study engages with the practice of monarchical rule under Gustav III, its ideological origins and power-political objectives as well as its symbolic expression. The study thereby addresses the very nature of kingship. In concrete terms, why did Gustav III, his court, and his civil service vigorously pursue projects that contemporaneous political opponents and, in particular, subsequent historiography have variously pictured as irrelevant, superficial, or as products of pure vanity? The answer, the study argues, is to be found in patterns of political practice as developed and exercised by Gustav III and his administration, which formed a significant part of the political culture of Gustavian Sweden. The dissertation is divided into three parts. The first traces the use and development of royal graces chivalric orders, medals, titles, privileges, and other gifts issued by the king. The practice of royal reward is illustrated through two case studies: the 1772 coup d état that established Gustav III s rule, and the birth and baptism of the crown prince, Gustav Adolf, in 1778. The second part deals with the establishment of the Court of Appeal in Vasa in 1776. The formation of the Appeals Court was accompanied by a host of ceremonial, rhetorical, emblematic, and architectural features solidifying its importance as one of Gustav III s most symbolic administrative reform projects and hence portraying the king as an enlightened monarch par excellence. The third and final part of the thesis engages with war as a cultural phenomenon and focuses on the Russo-Swedish War of 1788-1790. In this study, the war against Russia is primarily seen as an arena for the king and other players to stage, create and re-create as well as articulate themselves through scenes and roles adhering to a particular cultural idiom. Its codes and symbolic forms, then, were communicated by means of theatre, literature, art, history, and classical mythology. The dissertation makes use of a host of sources: protocols, speeches, letters, diaries, newspapers, poetry, art, medals, architecture, inscriptions and registers. Traditional political source material and literary and art sources are studied as totalities, not as separate entities. Also it is argued that political and non-fictional sources cannot be understood properly without acknowledging the context of genre, literary conventions, and artistic modes. The study critically views the futile, but nonetheless almost habitual juxtaposition of the reality of images, ideas, and metaphors, and the reality of supposedly factual historical events. Significantly, the thesis presumes the symbolic dimension to be a constitutive element of reality, not its cooked up misrepresentation. This presumption is reflected in a discussion of the concept of role , which should not be anachronistically understood as roles in which the king cast himself at different times and in different situations. Neither Gustav III nor other European sovereigns of this period played the roles as rulers or majesties. Rather, they were monarchs both in their own eyes and in the eyes of their contemporaries as well as in all relations and contexts. Key words: Eighteenth-Century, Gustav III, Cultural History, Monarchs, Royal Graces, the Vasa Court of Appeal, the Russo-Swedish War 1788–1790.

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.

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.

Genus i östra Nyland : från dialektutjämning till dialektmarkör

Gender in eastern Nyland – from dialect levelling to identity marking The study of dialect leveling in eastern Nyland focuses on variation and change in the Swedish dialects of Nyland (Fi. Uusimaa) on the south coast of Finland. During the last century the grammatical gender system of the dialects in the area has been reduced from a three-gender system to a two-gender system (cf. Corbett 1991). The present study is based on five linguistic variables in the gender system: the anaphoric pronouns (han, hon, den) when used for inanimates; the neuter pronouns he(t) and de(t) – when used anaphorically or as expletives; and three different types of morphological postposed definite articles. For all these variables, both dialect variants and standard variants are used in the dialects. Within the study of processes of variation and change, the work focuses on the mechanisms of leveling, simplification and reallocation; cf. Trudgill (1986) and Hinskens, Auer Kerswill (2005). With regard to the reductions of the gender system, the possibility that some of these variables might have turned into becoming dialect markers (Labov 1972) in the modern varieties of eastern Nyland is given special attention. The primary data consist of tape recordings with 25 informants done in the 1960s and 1970s. The informants were born in 1881–1913. In addition, recent changes were investigated in detail in tape recordings from 2005–2008 with 15 informants, who were born in the period 1927–1947 or 1976–1988. The study combines quantitative and qualitative methods in the systematic analysis of the data. Theoretically and methodologically the study relies on methods and results from variation studies and socio-dialectology, as well as on methods and results from traditional dialectology; cf. Ahlbäck (1946) and the dictionary of Swedish dialects, Ordbok över Finlands svenska folkmål, (1976–). The results show that there are different strategies among the informants in their use of the features studied. In the modern varieties of the dialects, most of the informants use only two genders, uter and neuter. Of the variables, the masculine pronoun for inanimates, the traditional neuter pronoun he(t) and some variants of the traditional definite articles have received a new function as dialect markers in my data. These changes first affect the gender distinctions, and the function of marking gender is lost; gradually the features then get new functions as dialect markers through processes of dialect leveling and reallocation. These processes are connected to changes taking place in the communities in eastern Nyland because of urbanization. When the dialect speakers experience that the traditional values of both the dialects and the culture are threatened, they begin to mark their dialectal identity by using dialect markers in their speech.

Editorial of "International Journal of Critical Indigenous Studies Volume 2, Number 1, 2009"

Over the past two decades neo liberalism has shaped global economic activity. The international reach of the current economic crisis propelled by the subprime mortgage meltdown in the United States has affected Indigenous communities in different ways to those whose investments were depleted by the Wall Street activities of an unregulated corporate and banking sector. Throughout this roller coaster economic ride the low socio-economic position of Indigenous peoples continued in Canada, the United States of America, New Zealand, Hawaii and Australia. The logic, or illogic of capital, failed to extend the boom of the economic upturn to Indigenous peoples, but is poised to extend the repercussions of the current downturn deep into Indigenous lives. The consistency of the Indigenous socio-economic position across these countries, even where treaties exist, indicates that the phenomenon is based on a shared Indigenous reality. In this special edition, the commonality in the way in which Indigenous people are engaged in and positioned by market forces and regulation by their respective nation states is proposed as one of the foundation plates of that Indigenous positioning...
