Nacksmärta hos kvinnor : effekten av individanpassad rehabilitering och betydelsen av arbetsmiljöfaktorer
No full textIntroduction: Musculoskeletal pain is a common problem in the working population. In Sweden, 40% of women and 30% of men report suffering from neck and shoulder pain weekly. The underlying cause for neck pain is often not known and the treatment is commonly guided by the individual’s symptoms. However, there is a lack of knowledge on how to receive the best effect based on the individual’s symptoms and functional limitations, and therefore this has been scarcely evaluated in research. Furthermore, the impact of work exposure and stress on long-term treatment for persons with neck pain is not clear. Aims: To develop (paper 1) and to evaluate a decision model for tailored treatment in women with neck pain (paper 2). Moreover, to determine if risk factors at work and stress influence intermediate and long-term treatment results (paper 3). Further, to investigate if changes in self-reported pain and disabilities are associated with changes of physical test outcomes of the neck and shoulder region after treatment (paper 4). Methods: In an RCT, 120 working women with non-specific neck pain were randomized to three different groups – tailored treatment (TT), non-tailored treatment (NTT) or treatment-as-usual (TAU) for an 11 weeks intervention with short-term, intermediate-term and long-term follow-ups. The TT group was guided by a decision model with cut-off levels to indicate impairments. The NTT group received two established treatment components randomly from those not indicated, and TAU group did not receive any treatment within the study. The RCT primary outcomes were self-reported neck pain and neck disability. A linear mixed model was used for analysing the effects. One week after the end of intervention work exposure and stress were assessed at a work-place visit and associations to treatment results were tested for, and mixed models were used to estimate longitudinal associations. Associations between self-reported neck problems and physical outcomes were estimated with univariate and multiple regressions analysis. Results: No differences between TT and NTT were revealed for neck pain and disability. In comparison to TAU, the TT and NTT groups both showed improvements at short-term follow-up, but not at intermediate and long-term follow-up. High stress level and low self-estimated control at work were associated with more pain and disability at the intermediate and long-term follow-ups. After intervention and at the intermediate-term follow-up, reduced neck pain, disability and frequency of symptoms were associated with increased peak speed of head rotation and cervical range of motion. Conclusion: Tailored treatment according to the decision model was not superior to the non-tailored treatment in women with non-specific neck pain. One explanation for this can be the weak relationships found between neck pain and disability and physical test outcomes. Further, perceived stress and psychosocial work exposure were associated with self-reported neck problems and should be taken into account to optimize the effects in neck pain rehabilitation.Bakgrund: Nack- och skulder-smärta är ett vanligt tillstånd som förekommer över hela världen. I Sverige skattar 30-40% besvär från nacke och skuldror mätt under en veckas tid. Generellt rapporterar kvinnor mer nack- och skulder-besvär än män. I avhandlingen är det ospecifik nacksmärta som har studerats, det inkluderar inte t.ex. Whiplash-skador, diskbråck eller andra mer specifika diagnoser. Den bakomliggande orsaken till ospecifik nacksmärta är, precis som beteckningen antyder, ofta inte känd och individens symptom och funktion är istället vägledande i undersökning och behandling samt utvärdering av behandling. Studier har visat att i jämförelse med friska har individer med ospecifika nackbesvär ofta sämre muskulär nackstyrka, minskad rörlighet i nacken och är något långsammare vid test av huvudrörelser. Behandlingen riktar sig ofta mot något av dessa fynd med bl.a. styrketräning av nackmuskler och/eller manuella tekniker för rörelseökning. Studier har dock visat att behandlingen endast ger måttliga resultat och att de positiva resultaten bara är kortvariga. I kliniken försöker man individanpassa behandlingen utifrån patientens behov men det finns väldigt lite forskning om detta utan studier utvärderar likadan behandling för hela grupper. Det saknas fortfarande kunskaper om hur man på bästa sätt individanpassar behandling så att den blir skräddarsydd utifrån individens symptom och funktion samt utvärderar detta. Syftet med avhandlingen var att undersöka om en intervention med skräddarsydd behandling (som också innehöll specifik aktiv träning) utifrån en beslutsmodell med fysiska tester och frågor om symtom är effektivt för att uppnå positiva effekter i självskattad smärta och funktion (artikel 1 och 2). Den skräddarsydda behandlingen jämfördes mot en grupp som fick samma upplägg men inte skräddarsydd behandling. Vidare undersöktes om båda dessa behandlingsgrupper var effektivare än en grupp som inte fick någon behandling i studien. Dessutom undersöktes om påverkan från arbetsmiljön i form av fysisk och psykosocial belastning samt upplevd stress påverkade behandlingsresultaten efter interventionen (artikel 3). Slutligen undersöktes om de fysiska testerna och den självskattade smärtan, funktionen och symptomen hade koppling till varandra dels före interventionen och dels i termer av förändringar efter interventionen (artikel 4). Metod: I en randomiserad kontrollerad interventionsstudie (RCT) inkluderades 120 kvinnor i åldrarna 20-65, alla i arbete, och som hade ospecifika nackbesvär. De lottades till tre grupper, (1) skräddarsydd behandling (Tailore treatment, TT), (2) icke-skräddarsydd behandling (Non-tailored treatment, NTT) och (3) en kontrollgrupp (Treatment-as-usual, TAU) som inte fick någon behandling i studien men var fria att söka vård på egen hand. Kvinnorna i TT-gruppen fick behandlings-komponenter utifrån testresultaten i beslutsmodellen. Det kunde läggas till någon behandlingskomponent om det visade sig behövas utifrån individens behov i vardagen. Detta undersöktes genom en strukturerad intervju-teknik som kallas Problem Elicitation Technique (PET). Kvinnorna i NTT-gruppen fick två lottade behandlings-komponenter som inte matchade deras behov utifrån testerna i beslutsmodellen. För båda behandlings-grupperna var interventionen 11 veckor med inbokade behandlingstillfällen 2-3 gånger per vecka, samtliga tillfällen vägledda av fysioterapeut. Data för alla tre grupper samlades in innan interventionen samt 3, 9 och 15 månader efter start av interventionen. Gruppskillnaderna analyserades med en ”linear mixed model”. En vecka efter intervention gjordes ett arbetsplatsbesök hos individerna i alla tre grupper. En erfaren ergonom observerade individernas fysiska arbetsbelastning med ett ergonomiskt bedömningsinstrument, Quick Exposure Check (QEC), och individerna skattade också den psykosociala arbetsmiljön i ett frågeformulär, QPS Nordic, samt upplevd stress. För att undersöka om den fysiska och psykosociala arbetsbelastningen samt stress påverkade resultaten från interventionen analyserades data med linjär regression och mixed model. För att undersöka om de fysiska testerna och den självskattade smärtan, funktionen och symptomen hade något samband användes linjär regressionsanalys. Resultat: Att skräddarsy behandlingen utifrån den testade beslutsmodellen var inte effektivare än att inte skräddarsy. I jämförelse med kontrollgruppen självskattade båda behandlingsgrupperna mindre smärta, bättre funktion och mindre symptom efter interventionen. I de länge uppföljningarna (9 och 15 månader) var dock skillnaderna mellan grupperna inte längre signifikanta förutom att båda behandlingsgrupperna, till skillnad från kontrollgruppen, upplevde sig bättre än innan behandling. Det visade sig att upplevd hög stressnivå och låg kontroll på arbetet hade samband med mer självskattad nacksmärta, sämre funktion och lägre arbetsproduktivitet. De fysiska testerna och självskattade nackbesvär hade bara svaga samband. På baslinjenivå, innan interventionen, fanns det samband mellan hög nackstyrka och låg självskattad funktion och låg frekvens på symptomen, samt mellan att vara långsam i testet av snabba huvudrörelser och hög smärta. Efter interventionen hade individernas förändring i självskattad smärta fortfarande bara samband med snabba huvudrörelser. Förbättring i självskattad funktion och symptom hade samband till ökad hastighet i snabba huvudrörelser och ökat rörelseutslag nackrotation. Sammanfattning: För kvinnor i arbete med ospecifika nackbesvär var det inte mer effektivt att skräddarsy behandling/träning utifrån en beslutsmodell jämfört med att slumpmässigt välja ut behandlingskomponenter från samma behandlingsarsenal. En förklaring kan vara att det fanns endast låga samband mellan självskattad smärta och funktion och de fysiska testerna. Upplevd stress och kontroll i arbetet visade sig ha samband med självskattad smärta, funktion och arbetsproduktivitet och bör tas i beaktande i framtida interventioner för individer med nacksmärta.
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
