Kön, kroppsbild och dysfunktionella tankar : en sambandsstudie

Body esteem is the affective aspect of body image, which is shaped by social experience. Compared with men, women have a more negative body image, which is more frequently correlated with depression and dysfunctional thoughts, especially in the case of eating disorders. The purpose of the present study was to examine gender differences in body esteem and its subcategories, and to find out whether there exists a stronger link between negative body esteem and higher levels of dysfunctional thoughts in women. The relationship between body esteem, dysfunctional thoughts and mental illness was examined. Participants were 73 college students doing social sciences and sports training educations. Body esteem questionnaire and dysfunctional thoughts questionnaire as well as a self made questionnaire on mental illness were used. Results showed that women had a more negative body esteem compared to men, especially considering weight. In women, there was a medium-strong negative relation between body esteem and dysfunctional thoughts. The results indicate that the norms for female body ideal that abound in the Western society have a negative affect on women's thinking and body image.Key words: Gender, body esteem, dysfunctional thoughts, mental illness.

Meanings of overweight In societal discourses overweight is defined as a growing individual and a social problem leading to sickness and disability, mental distress, increased use of health care and reduced economic productivity. A strong normative pressure is directed at the overweight but relatively few succeed in reducing their weight. Therefore, the overweight need to manage a double stigma; the overweight body per se and their inability to conform to norms about bodyweight. This article investigates how individuals present their overweight to their social environment. Empirical data was collected as part of an evaluation study of a keep-fit project directed at home-care staff. Qualitative interviews were conducted with 49 participants and 30 of them had either tried or were trying to reduce their weight. The analysis shows that the informants presented a divided self consisting of a biological body, with its own drives, and a mind that is aware of the body and its social meanings. They portrayed their lives as a battle between these two sides. Their presentations of the divided self can be analysed as a defence of their social selves. The overweight can account for the kilos by blaming the biological drives, which leaves the core of themselves – their minds – unblemished. They can express an intention to loose weight and thereby conform to norms about bodyweight. When they fail to loose weight, the responsibility can be attributed to the unruly body.

Kroppsideal via Instagram

Syfte Dagens teknik har medfört en explosion av nätbaserade sociala medier där bilder av träning och kroppar är ett tydligt fenomen. Syftet med detta arbete har varit att undersöka hur kroppsideal skapas och framställs på internet och framförallt sociala medier. Till hjälp användes frågeställningarna: Hur gestaltar manliga fitness-profiler sig själv och sina kroppar på den nätbaserade tjänsten Instagram? Finns det kopplingar mellan dessa profilers kroppsgestaltningar och specifika kroppsideologier? (Rosenmann & Kaplan, 2014) Metod Arbetet utfördes med netnografisk metod i grunden, en metod specifikt fokuserad på kvalitativ forskning av internet. Tre manliga fitnessprofiler samt fem av varje profils bilder valdes utifrån popularitet på Instagram för att granskas och analyseras i relation till kroppsideal. Resultat Bilderna hade gemensamma egenskaper då dessa, ofta i gymmiljö, visade avklädda, extremt muskulösa kroppar med fokus på framsidan av överkroppen. Skilda egenskaper förekom, dock inte i någon signifikant bemärkelse. Kroppsideologin metrosexuella-och konsumentmaskuliniteten (Rosenmann & Kaplan, 2014) präglade profilerna. Slutsatser Dessa fitnessprofilers framställning av sina kroppar stämde väl överens med dagens rådande muskulära kroppsideal som innefattar en slimmad, muskulös, väldefinierad kropp. Tydliga kopplingar kunde också göras till Rosenmann’s och Kaplan’s (2014) kroppsideologi; metrosexuella-och konsumentmaskuliniteten.

Visuell Perception : En studie av visuella faktorer kring ett musikaliskt framträdande

The essay investigates the visual element as seen by the audience and artist to be of greatest importance to a musicalperformance. The study was conducted in the form of a field work which included doing interviews with artists, surveys of the audience and interpretive observations of live performance. The fieldwork was conducted in three different environments in which I found myself on the spot and performed the various stages included in the field work. It was done to create a surface that could be used in an essay, and through that use this material to compare and analyze my results and in the end be able to answer my questions. I started from eight different factors which all could beexperienced visually on stage. The factors were light / colors, costumes, props, effects, stage presence, attitude / image, nervousness and dance / body language. Those factors would then be examined in the various musical performances and to be answered by the audience and performers which of those factors they considered to be of great importance or small importance when it comes to visual perception in a musical context. The result was a clear statement where two factors were considered to be most crucial for a musical performance, and a clear statement in which two factors were considered by the majority to be less important. The results demonstrate a common understanding what the artist and the audience thinks is important. A result that can act as a template for what an artist should think about regarding the visual elements before an performance. My theory is my assumption that the visual elements of musical performances can play an important or decisive role, an assumption that was strengthened by my empirical experiences at a concert visit. I wanted in this essay explore and give a clear picture of what it is that artists and audiences consider to be visually crucial for a musical context

Kan ett synintryck upphäva en ljudillusion? : En undersökning av oktavillusionen kopplad till visuella stimuli i form av noter

The present study origins from Diana Deutschs work with the octave illusion and investigates if musically trained subjects can give a more correct perception of the octave illusion if their visual senses also get stimulated in form of scores.Ten subjects, with over 20 years experience playing an instrument, participated in the investigation. The result shows that a more correct perception of the octave illusion depends on the educational level in scorereading. Four out of five subjects who valued their knowledge in scorereading as being good or very good reported that the score corresponded to what they could hear in the right ear, which is connected to the dominant hemisphere. When they were instructed to focus on both ears three of these subjects reported that the score corresponded to what they could hear in the left ear, but that they could not hear the lower tone in the right ear. As the scores for the right ear were equal for the identical soundexamples this perception could be an indication that stimuli are percieved as being complex and the interpretation is alternated to the non dominant hemisphere.

Typografiska riktlinjer och textframställning för smartphones

Idag använder allt fler människor sina smartphones för att surfa och använda tjänster online. Detta innebär att en stor del text läses på små skärmar. Detta arbete handlar om hur text bäst utformas och struktureras för att enklast kunna läsas och uppfattas på en mobilskärm. Faktorer som berörs är typgrad, ljusrum, textlängd, teckensnittsklass, radlängd, bild i text och kontrastverkan. Arbetet utgår från en normativ, svensk person utan funktionsnedsättningar. Arbetet är grundat på litteratur, egna analyser, intervjuer med branschfolk, enkätundersökning och test med fokusgrupp. Resultatet blev att en text på smartphone bäst utformas med flera styckesindelningar i form av blankrader, med bilder där bilden tillför något i informativt syfte och textlängd baserat på ämneskategori. Bilden bör sättas ovanför brödtexten. Längre texter ska sättas med scrollfunktion. Kontrast har stor betydelse på mobiltelefoner, texter går bra att läsa även när de är satta negativt. Teckensnittsklass är enligt resultatet av denna rapport inte av betydelse. Både seriff och sanserif kan läsas utan problem på smartphones. Typgraden bör förstoras något i förhållande till telefonens default-inställningar. På grund av att text på skärm inte stödjer avstavningar rekommenderas korta ord där det är möjligt för att förhindra en allt för hackig högerkant.

Multimodal Literacy as a form of Communication : What is the state of the students at Dalarna University multimodal literacy?

Literacy is an invaluable asset to have, and has allowed for communication, documentation and the spreading of ideas since the beginning of the written language. With technological advancements, and new possibilities to communicate, it is important to question the degree to which people’s abilities to utilise these new methods have developed in relation to these emerging technologies. The purpose of this bachelor’s thesis is to analyse the state of students’ at Dalarna University mulitimodal literacy, as well as their experience of multimodality in their education. This has led to the two main research questions: What is the state of the students at Dalarna University multimodal literacy? And: How have the students at Dalarna University experienced multimodality in education? The paper is based on a mixed-method study that incorporates both a quantitative and qualitative aspect to it. The main thrust of the research paper is, however, based on a quantitative study that was conducted online and emailed to students via their program coordinators. The scope of the research is in audio-visual modes, i.e. audio, video and images, while textual literacy is presumed and serves as an inspiration to the study. The purpose of the study is to analyse the state of the students’ multimodal literacy and their experience of multimodality in education. The study revealed that the students at Dalarna University have most skill in image editing, while not being very literate in audio or video editing. The students seem to have had mediocre experience creating meaning through multimodality both in private use and in their respective educational institutions. The study also reveals that students prefer learning by means of video (rather than text or audio), yet are not able to create meaning (communicate) through it.

Motion Cues Analysis for Parkinson Gait Recognition

Background: Previous assessment methods for PG recognition used sensor mechanisms for PG that may cause discomfort. In order to avoid stress of applying wearable sensors, computer vision (CV) based diagnostic systems for PG recognition have been proposed. Main constraints in these methods are the laboratory setup procedures: Novel colored dresses for the patients were specifically designed to segment the test body from a specific colored background. Objective: To develop an image processing tool for home-assessment of Parkinson Gait(PG) by analyzing motion cues extracted during the gait cycles. Methods: The system is based on the idea that a normal body attains equilibrium during the gait by aligning the body posture with the axis of gravity. Due to the rigidity in muscular tone, persons with PD fail to align their bodies with the axis of gravity. The leaned posture of PD patients appears to fall forward. Whereas a normal posture exhibits a constant erect posture throughout the gait. Patients with PD walk with shortened stride angle (less than 15 degrees on average) with high variability in the stride frequency. Whereas a normal gait exhibits a constant stride frequency with an average stride angle of 45 degrees. In order to analyze PG, levodopa-responsive patients and normal controls were videotaped with several gait cycles. First, the test body is segmented in each frame of the gait video based on the pixel contrast from the background to form a silhouette. Next, the center of gravity of this silhouette is calculated. This silhouette is further skeletonized from the video frames to extract the motion cues. Two motion cues were stride frequency based on the cyclic leg motion and the lean frequency based on the angle between the leaned torso tangent and the axis of gravity. The differences in the peaks in stride and lean frequencies between PG and normal gait are calculated using Cosine Similarity measurements. Results: High cosine dissimilarity was observed in the stride and lean frequencies between PG and normal gait. High variations are found in the stride intervals of PG whereas constant stride intervals are found in the normal gait. Conclusions: We propose an algorithm as a source to eliminate laboratory constraints and discomfort during PG analysis. Installing this tool in a home computer with a webcam allows assessment of gait in the home environment.

Automating condition monitoring of vegetation on railway trackbeds and embankments

Vegetation growing on railway trackbeds and embankments present potential problems. The presence of vegetation threatens the safety of personnel inspecting the railway infrastructure. In addition vegetation growth clogs the ballast and results in inadequate track drainage which in turn could lead to the collapse of the railway embankment. Assessing vegetation within the realm of railway maintenance is mainly carried out manually by making visual inspections along the track. This is done either on-site or by watching videos recorded by maintenance vehicles mainly operated by the national railway administrative body. A need for the automated detection and characterisation of vegetation on railways (a subset of vegetation control/management) has been identified in collaboration with local railway maintenance subcontractors and Trafikverket, the Swedish Transport Administration (STA). The latter is responsible for long-term planning of the transport system for all types of traffic, as well as for the building, operation and maintenance of public roads and railways. The purpose of this research project was to investigate how vegetation can be measured and quantified by human raters and how machine vision can automate the same process. Data were acquired at railway trackbeds and embankments during field measurement experiments. All field data (such as images) in this thesis work was acquired on operational, lightly trafficked railway tracks, mostly trafficked by goods trains. Data were also generated by letting (human) raters conduct visual estimates of plant cover and/or count the number of plants, either on-site or in-house by making visual estimates of the images acquired from the field experiments. Later, the degree of reliability of(human) raters’ visual estimates were investigated and compared against machine vision algorithms. The overall results of the investigations involving human raters showed inconsistency in their estimates, and are therefore unreliable. As a result of the exploration of machine vision, computational methods and algorithms enabling automatic detection and characterisation of vegetation along railways were developed. The results achieved in the current work have shown that the use of image data for detecting vegetation is indeed possible and that such results could form the base for decisions regarding vegetation control. The performance of the machine vision algorithm which quantifies the vegetation cover was able to process 98% of the im-age data. Investigations of classifying plants from images were conducted in in order to recognise the specie. The classification rate accuracy was 95%.Objective measurements such as the ones proposed in thesis offers easy access to the measurements to all the involved parties and makes the subcontracting process easier i.e., both the subcontractors and the national railway administration are given the same reference framework concerning vegetation before signing a contract, which can then be crosschecked post maintenance.A very important issue which comes with an increasing ability to recognise species is the maintenance of biological diversity. Biological diversity along the trackbeds and embankments can be mapped, and maintained, through better and robust monitoring procedures. Continuously monitoring the state of vegetation along railways is highly recommended in order to identify a need for maintenance actions, and in addition to keep track of biodiversity. The computational methods or algorithms developed form the foundation of an automatic inspection system capable of objectively supporting manual inspections, or replacing manual inspections.

Musikalisk gestaltning av en ”image” : - En fallstudie i design av narrativ mediemusik -

Studien ligger inom ramen för Ljud- och musikproduktion och bygger på ett case där en varumärkesmelodi/ musiklogotype till ett musikgymnasium ska designas. Syftet med studien är att utforska hur en image kan gestaltas musikaliskt och däri bättre förstå hur forskning genom design och användarmedverkan - påverkar och bidrar till processen inom design av narrativ mediemusik. Studien har ämnat svara på den övergripande frågeställningen: Hur kan komposition av narrativ musik beskrivas och genomföras som en designprocess? Forskningsfrågan innefattar även subfrågorna: Hur bidrar användarmedverkan till arbetsprocess vid design av narrativ mediemusik? Hur bidrar gruppsammansättning, själva processen och processverktygen till ett musikaliskt relevant resultat? Med formuleringen "ett musikaliskt relevant resultat" avses i studiens kontext en musikalisk prototyp/slutprodukt som har potential att kunna uttrycka känslor och värderingar som kan överensstämma med varumärkets (skolans) image och formulerade värderubriker. Kärnan i arbetet ligger inom fälten forskning genom design och användarmedverkan, där deltagarna under arbetsprocessens gång kontinuerligt och i flera processteg bidragit genom diskussioner, reaktioner, resonemang och konkreta förslag. Studien visar att designarbete inom narrativ mediamusik tillsammans med representanter för användarna/ målgruppen kan generera fler idéer om aspekter specifika för arbete med design av narrativ mediemusik samt bidra till större förståelse för aktuella kontexter (målgrupps-relaterade och process-relaterade kontexter såväl som musikaliska och genre-relaterade kontexter), än om designern arbetar ensam. Av vikt är att under designprocessen ta fram flera versioner av prototyperna, att göra olika instrumenteringar och interpretationer av det musikaliska materialet, där ett av målen med prototyperna är att designer stegvis lär sig vad som fungerar - vad som skapar en klingande mening i den aktuella målrelaterade kontexten - och ett sätt att kommunicera den här kunskapen är att designa och pröva flera olika prototyper i klingade form.
