Utveckling av en kommunikationsstrategi kring hållbar vattenanvändning / Development of a Communication Strategy for Sustainable Water Use

Lindeborg, Petra January 2021 (has links)
Syftet med studien har varit att kartlägga Norrvattens kommunikation kring hållbar vattenanvändning med sina medlemskommuner och medlemskommunernas kommunikation med kommuninvånarna. Ytterligare ett syfte med studien har varit att kartlägga hur andra VA-organisationer har kommunicerat kring hållbar vattenanvändning. Kartläggningarna har gjorts utifrån perspektiven hur kommunikationen genomförts, vad som kommunicerats och med vilket syfte. För att synliggöra kommunikationen har en didaktisk analys gjorts utifrån de didaktiska frågorna vem, vad, varför, när och hur. Slutligen har studien syftat till att utveckla ett underlag för en kommunikationsstrategi för Norrvattens kommunikation med medlemskommuner och kommuninvånare. Grunden i resultatet av kartläggningen av kommunikationen och enligt tidigare forskning ska kommunikationen syfta till att stärka möjligheter att hantera dricksvattenefterfrågan för hållbar vattenanvändning. I studien framkom att kommunikationen kring hållbar användning av vatten syftar till att förändra individers beteenden, för att minska den onödiga användningen av vatten. Respondenterna lyfter också fram att kommunikationen bör syfta till att öka vattnets värde samt öka kunskapen kring produktionen och produktionskapaciteten. Innehållsmässigt visar resultaten att kommunikationen ska beröra konkreta och praktiska handlingar, teknisk fakta och vattnets kretslopp i det större perspektivet. Olika kommunikationskanaler passar för olika typer av kommunikation, där resultatet visar att navet för kommunikationen med kommuninvånare är webben och sociala medier. Tonalitet, timing och sociala aspekter av kommunikationen framställdes i resultatet också som viktiga delar. Dessa har på olika sätt inkluderats i kommunikationsstrategin. Kommunikationsstrategin har utvecklats baserat på en modell framställd utifrån den teoretiska grund som använts i studien. Modellen har framställts som ett fundament medan resultatet från kartläggningarna av Norrvatten, medlemskommunerna och VA-organisationernas kommunikation tillsammans med tidigare forskning har utgjort innehållet. / The aim of this study was to map Norrvatten’s communication regarding sustainable water usage with Norrvatten’s municipalities and the municipalities’ communication with the municipal residents. Furthermore, the aim has also been to map how other water and sewerage organizations have communicated about sustainable water use. Focus of the systematic mapping of the communication was on how the communication was carried out, what was communicated and for what purpose. To understand the communication, a didactic analysis was carried out based on the didactic questions of who, what, why, when, and how. The last purpose of the study aimed to develop basis for a communication strategy for Norrvatten's communication with member municipalities and municipal residents. This was done based on the results of the communication mapping and previous research. The communication intends to strengthen opportunities to handle potable water demand relative to sustainable use of water. The result showed that communication about sustainable use of water aim to change individuals' behaviors, to reduce the unnecessary use of water. The respondents also emphasize that communication should aim to increase the value of water and increase knowledge of the production and production capacity. In terms of content, the results show that the communication touches on concrete and practical actions, technical facts, and the water cycle in the larger perspective. Communication channels are suitable for different types of communication, where the results show that the hub of communication with municipal residents is the website and social media. Tonality, timing, and social aspects of the communication were also presented in the result as important parts. These have been included in the communication strategy. The communication strategy was developed on a model produced on the theoretical basis used in the study. The model has been presented as a foundation, while the results from the communication mapping of Norrvatten, the member municipalities and the VA organizations' communication together with previous research have constituted the content.

Finns det evidens för att höghastighetsmanipulation av nacken kan orsaka stroke? / Is there evidence that high velocity manipulation of the cervical spine can cause stroke?

Eriksson, Andreas January 2020 (has links)
Höghastighetsmanipulation av nacken är en manuell behandlingsteknik mot smärta i framförallt nacken och skuldrorna. Tekniken har enligt flera källor visats hänga samman med risken för att drabbas av skador på de kärl som försörjer hjärnan med blod, med bland annat stroke som följd. Andra källor har å andra sidan visat att de är en teknik som är säker att utföra. Den här litteraturstudien har sammanställt och utvärderat forskning som på olika sätt söker utreda om det påstådda sambandet är kausalt eller inte. Metoden som valdes var att genom en av SBU färdigställd mall värdera forskningsartiklar och sedan sortera dem efter relevans, för att på så sätt avgöra huruvida sambandet kan ses som kausalt eller inte. Studieresultatet visade att frågan är för komplex för att kunna besvaras i en enskild studie, och att mer forskning behövs inom flera delområden innan frågan kan besvaras fullt ut. Orsaken till detta är att det finns flera orsaksmekanismer, och flera riskgrupper, för denna typ av skada, där flera ännu är okända. Detta gör att en fullständig kartläggning av samband i frågan ännu inte är möjlig. Däremot är det sannolikt att tekniken kan verka som en utlösande faktor, en trigger, hos vissa personer i riskgrupperna. Därför kan det sägas finnas en risk med tekniken rent praktiskt, oavsett om ett kausalt samband mellan tekniken och stroke i sig existerar eller inte. / High Velocity Manipulation of the cervical spine is a manual treatment technique against pain in foremost the neck, shoulders. The technique has according to multiple sources been connected to the risk of injury to the blood vessels that supply the brain with blood, with among others stroke as a consequence.  Other sources have on the other hand shown it the technique to be safe to perform. This literature study has compiled and evaluated research that in various ways tries to find out if said connection is causal The method used was to evaluate articles through a pre-made form from SBU, and then to sort them according to relevance to see if the connection is causal or not. The result showed that the question is too complex to be answered in a single study, and that more research is needed to answer the question in full. This is due to the fact that there are multiple mechanisms behinds this form om injury, that the risk seems to exists in certain groups, and that some of these are not yet identifiable. On the other hand there is a high probability that the technique might act as an activating factor in these groups. Because of this there can be said that a risk exists with the technique in practice, no matter if there is a casual connection between the technique and stroke in itself or not.

Η διερεύνηση των λεξικών σχέσεων ομωνυμιών, μετωνυμιών ως διαγνωστικό εργαλείο στην άνοια

Αναστασοπούλου, Χαρίκλεια 11 October 2013 (has links)
Είναι γνωστό ότι η άνοια σχετίζεται με την απώλεια μνήμης, έκπτωση γλωσσικών ικανοτήτων, έλλειψη αυτονομίας και απώλεια της προσωπικής ταυτότητας του ασθενούς. Στόχος της παρούσας εργασίας είναι να αναδείξει τη σχέση αμφισημίας- άνοιας και να διερευνηθεί η σκοπιμότητα ύπαρξης ενός μεθοδολογικού εργαλείου για την εκτίμηση και τη διερεύνηση της γλωσσικής έκπτωσης στη άνοια μέσα από την γλωσσική επεξεργασία των λεξικών σχέσεων (μεταφορών –ομωνυμίας- μετωνυμιών) και να παρουσιάζει το προφίλ των ασθενών αυτών. Στην πρώτη ενότητα παρουσιάζω γενικά στοιχεία για την νόσο της άνοιας αλλά και στοιχεία για τους κυριότερους τύπους της νόσου όσον αφορά την γλωσσική συμπεριφορά των ασθενών. Στην ενότητα αυτή αναφέρω επίσης βασικά διαγνωστικά εργαλεία που χρησιμοποιούνται ευρέως για τον προσδιορισμό της νόσου, ενώ αναλυτικότερα στοιχεία για τα εργαλεία που χρησιμοποιούνται και τις δομές που εξετάζουν παρατίθενται στο παράρτημα. Κλείνοντας την ενότητα καταλήγω στα οφέλη και την αναγκαιότητα ύπαρξης πρώιμης διάγνωσης. Στην δεύτερη ενότητα αναφέρομαι κυρίως στο νοητικό λεξικό και στην δυσκολία πρόσβασης των ασθενών με πιθανή άνοια σε αυτό. Επιπλέον υπάρχουν στοιχεία για την λεξική κατάκτηση, επιλογή και ανάκτηση των πληροφοριών και φαίνεται η σχέση νοητικού λεξικού – αμφισημίας. Στην τρίτη ενότητα παρουσιάζω το φαινόμενο της αμφισημίας από την θεωρητική άποψη αρχικά της γλωσσολογίας, πως κατακτώνται οι αμφίσημες λέξεις και επεξεργάζονται σε σχέση με την ηλικία και καταλήγω στην νευρική συσχέτιση των λεξικών αμφισημιών με συγκεκριμένες εγκεφαλικές περιοχές. Στο τέλος της παρούσας ενότητας παρουσιάζω ευρήματα/ συμπεράσματα από πλήθος ερευνών που αφορούν την λεξική αμφισημία με διαφορετικές μεθόδους για κάθε τύπο άνοιας. Στην τελευταία ενότητα παρουσιάζω τις βασικές υποθέσεις μου πως η χρήση των λεξικών σχέσεων θα μπορεί να αποτελέσει διαγνωστικό εργαλείο στην άνοια. Επίσης παρουσιάζω την κατασκευή και τα αποτελέσματα της πειραματικής διαδικασίας ανάμεσα σε τέσσερα διαφορετικά υποκείμενα (πασχόντων –υγειών) διαφορετικής παθολογίας και σοβαρότητας. Ακολουθεί τέλος το παράρτημα με στοιχεία που αφορούν την διαφοροδιάγνωση της νόσου βάσει αλγορίθμων με τα γνωστικά ελλείμματα όπως παρουσιάζονται από τους φροντιστές των ασθενών αλλά και παθολογικών συμπτωμάτων που παρουσιάζουν, ενώ σε πίνακα υπάρχουν τα γλωσσικά στοιχεία που βοηθούν επίσης στην διαφοροδιάγνωση των κυριότερων τύπων άνοιας και τα αποτελέσματα της πειραματικής διαδικασίας. / It is well known that dementia is associated with memory loss, impaired language skills, lack of autonomy and loss of patients’ independence. The aim of this paper is to highlight the connection between ambiguity and dementia, and to investigate the feasibility of a methodological tool to assess and investigate the linguistic deduction in dementia through the linguistic processing of lexical relations (metaphor-homonymy-metonymy) and present the profile of such patients. In the first section I present general information as well as the linguistic features of the main types of dementia. In this section there is also a report on the diagnostic tools which are widely used to identify the disease. More detailed information about the use of these diagnostic tools is listed in the Annex. At the end of this section there is evidence about the benefits and the importance of early diagnosis. The second section is mainly referred to the mental lexicon and the difficulty patients with probable dementia face in accessing it. Furthermore there is evidence for lexical acquisition, selection and retrieval of information which shows the mental lexicon – ambiguity connection. In the third section I present the phenomenon of ambiguity, starting from the theoretical linguistic view; how the ambiguous words are conquered and processed in relation to age and lead to neural correlation of lexical ambiguity with specific brain regions. At the end of this section I present findings / conclusions of several researches, using different methods, on the lexical ambiguity on each type of dementia. The last section presents my basic assumptions concerning how the use of lexical relations can be a diagnostic tool in dementia. Furthermore, I present the construction and the results of the experimental process between four different subjects (patient-healthy) with different pathology and severity of the disease. Finally, at the annex, I present data on the differential diagnosis of the disease based on algorithms with cognitive deficits reported by caregivers of patients as well as pathology features. Also there is a board with differential linguistic elements which help distinguish the main types of dementia, along with the experimental material used and the results of the procedure.

Zaměstnávání osob se zrakovým postižením / Employment of people with visual impairment

Balková, Nikola January 2017 (has links)
The thesis deals with employing visually impaired people and support for their employability in the labour market. The purpose of the work is to explain the issues connected with the employment, its possibilities and ways of support in this area aimed at visually impaired people. The empirical part is based on the assessment of conditions of participation of visually impaired people in retraining courses organised by Dědina Residential Physiotherapy and Retraining Centre for Visually Impaired People. Its verification was performed using the following methods: analysis of the specialist literature, interviews, analysis of the interviews, observation and interviews with the specialist staff. The research showed that retraining courses organised by Dědina Residential Physiotherapy and Retraining Centre for Visually Impaired People are an important means of support for employment of visually impaired people from all over the country. The established facts show that retraining of any specialisation is necessary in order to enable the target group to find a suitable job. The aim of this work was to establish the objective and subjective benefits for the individual participants of a retraining course for Blind and Visually Impaired Masseurs and to point out that free labour market is not sufficiently...

Ett hål i känseln : Om språkupplevelsens fenomenologi i Ann Jäderlunds författarskap

Wiklander, Osvald January 2019 (has links)
This thesis aims to analyze and interpret a number of central works – Vimpelstaden (1985), Som en gång varit äng (1988), Blomman och människobenet (2003), I en cylinder i vattnet av vattengråt (2005) and Vad hjälper det en människa om hon häller rent vatten över sig i alla sina dagar (2009) – by the Swedish poet Ann Jäderlund (1955-) in the context of phenomenology and affect theory. The analysis consists of three chapters and proceeds chronologically with technical scrutinies of separate phases of Jäderlund’s œuvre – from the aphasic-like treatment of established phraseologies in Vimpelstaden and frozen expressions of the botanical discourse in Som en gång varit äng, to the uncanny focus on perceptual patterns as such in her later works. Throughout these analyses the thesis observes a series of techniques with which the author presents us with a kind of sensory paradox, through a) creating language-based complex appearances, non-appropriable by means of the normal perceptual patterns of embodied perception, while still b) simulating, and thus implicitly emphasizing, these appearances as something already concretely looked at and felt. In short, to experience what cannot be experienced, to live the unlivable. Many of these technical observations made are pinned down analytically using concepts from the field of cognitive poetics, namely George Lakoff and Mark Johnsons findings of experiential image schemata underpinning spoken phraseologies and their influential theories on conceptual metaphors. The interpretative conclusion following these observations is that Jäderlund handles her writing aesthetically as a kind of sensory material in a very literal sense, a “being of sensation” in the terminology of French philosophers Gilles Deleuze and Felix Guattari. Not as means of experiential or intellectual representation, not as some sort of critical enterprise through mere language-gaming of free- floating signifiers – but as a material able to preserve and perform sensory processes immanent to its own material compilation, a tendency that earlier research fails to grasp or simply ignores altogether. Thus the affectivity immanent to the literary material – often being the starting point of studies in affect theory and cognitive poetics – is here proven to be a characteristic, thereby playing the role more of a conclusion than a field of inquiry. The aesthetics of interrogating the limits of sensory experience, introducing a sort of crisis to embodied perception through the experience of poetic language – and the experience of it as having a “metaphysical significance”, as French phenomenologist Maurice Merleau- Ponty puts it – is articulated in the thesis against the background of influential readings of modern art carried out by Merleau-Ponty and Deleuze.

Towards a Nuanced Evaluation of Voice Activity Detection Systems : An Examination of Metrics, Sampling Rates and Noise with Deep Learning / Mot en nyanserad utvärdering av system för detektering av talaktivitet

Joborn, Ludvig, Beming, Mattias January 2022 (has links)
Recently, Deep Learning has revolutionized many fields, where one such area is Voice Activity Detection (VAD). This is of great interest to sectors of society concerned with detecting speech in sound signals. One such sector is the police, where criminal investigations regularly involve analysis of audio material. Convolutional Neural Networks (CNN) have recently become the state-of-the-art method of detecting speech in audio. But so far, understanding the impact of noise and sampling rates on such methods remains incomplete. Additionally, there are evaluation metrics from neighboring fields that remain unintegrated into VAD. We trained on four different sampling rates and found that changing the sampling rate could have dramatic effects on the results. As such, we recommend explicitly evaluating CNN-based VAD systems on pertinent sampling rates. Further, with increasing amounts of white Gaussian noise, we observed better performance by increasing the capacity of our Gated Recurrent Unit (GRU). Finally, we discuss how careful consideration is necessary when choosing a main evaluation metric, leading us to recommend Polyphonic Sound Detection Score (PSDS).

Hållbarhetsarbete och kommunikation : En studie av AB Bollnäs Bostäders verksamhet / Sustainability work and communication : A study of AB Bollnäs Bostäder´s business

Guttenkunst, Ia January 2017 (has links)
Syftet med studien har varit att synliggöra AB Bollnäs Bostäders hållbarhetsarbete utifrån 18 framtagna hållbarhetskategorier fördelade på de ekologiska, sociala och ekonomiska hållbarhetsaspekterna. De ekologiska och sociala hållbarhetskategorierna är tagna från ISO26000, en standard som beskriver företags samhällsansvar, och de ekonomiska hållbarhetskategorierna är framtagna med utgångspunkt i tidigare forskning och dokument gällande hållbarhetsaspekter i fastighetsbranschen. Vidare har studien som syfte att synliggöra kommunikationen kring hållbarhetsarbetet genom att analysera vad som kommuniceras och vad resultatet blir av den kommunikationen. Det har gjorts genom att göra en didaktisk analys utifrån de didaktiska frågorna för vem, varför, vad och hur. Slutligen har studien som syfte att visa på vad det finns för visioner internt och externt kring AB Bollnäs Bostäders framtida hållbarhetsarbete, med grund i de 18 hållbarhetskategorierna. För att samla in relevant empiri har personliga intervjuer, enkäter och dokumentstudier genomförts. Resultatet visar på att AB Bollnäs Bostäder arbetar aktivt mot en hållbar utveckling utifrån alla tre hållbarhetsaspekter - ekologisk, social och ekonomisk. Utav 18 hållbarhetskategorier bedömdes arbetet med 14 av dem vara tillfredsställande. Med välinvesterade resurser skulle bolaget kunna utveckla sitt hållbarhetsarbete och uppfylla alla 18 hållbarhetskategorier. Kommunikationen kring hållbarhetsarbetet uppvisar övervägande ekonomiskt innehåll både internt och externt, men med olika syften för de olika målgrupperna boservice, ekonomi och administration, kundcenter, parkenheten, tekink, VD, boende, entreprenörer, kommunfullmäktige samt styrelsen. Utfallet däremot visar på att det är de ekonomiska, sociala och ekologiska hållbarhetskategorierna, i nämnd ordning, som uppfattas av de olika målgrupperna. Slutligen framgick det av resultatet att alla tre hållbarhetsaspekter ansågs vara viktiga för AB Bollnäs Bostäder i framtiden, men de ekonomiska hållbarhetskategorierna bedömdes ha högre prioritet. Nyckelord: / The objective has been to visualize sustainability work of AB Bollnäs Bostäder, based on 18 sustainability categories developed in the study, divided on the sustainable aspects ecological, social and economical. The ecological and social aspect of the sustainability categories is part of the ISO26000, a standard describing company’s social responsibility, and the economic aspect is developed based on research and document discussing sustainable development in the property business. Furthermore, the aim has also been to study the communication of the sustainability work at the company, and see the result of it. It was accomplished by a didactic analysis, based on the didactical questions for who, why, what and how. The last object of the study has been to learn the visions of the future sustainability work of AB Bollnäs Bostäder, from different groups perspectives, based on the 18 sustainability categories. To collect relevant empirical data, personal interviews, questionnaires and document studies has been carried out. The results show that active work towards a sustainable development is performed in AB Bollnäs Bostäder, from all three aspects of sustainable development – ecology, social and economy. Out of the 18 sustainability categories, the work of 14 of them was assessed to be satisfying. Well invested resources would help the company to develop their work, and fulfil all the sustainability categories. The communication of the sustainability categories showed a consideration towards an economical content, both internally and externally, but with different aims for the targeted groups property service, economic and administrations, customer centre, park division, technical, CEO, inhabitants, entrepreneurs, municipal council and the board. The outcome of the communication on the other hand, showed that the economical, social and ecological sustainability categories, in the stated order, is interpreted different by the targeted groups. Finally, the results showed that all three sustainability aspects were important for AB Bollnäs Bostäder in the future, but the economical sustainability categories were considered to have a higher priority.
