Från ord till handling: bakom konsumenternas gröna fasad : En studie om gapet mellan attityd och handling inom den svenska klädindustrin.

Landén, Emma, Noor, Nazmee January 2023 (has links)
The subject of sustainable development is growing in relevance, and never before has research on the subject been as essential. Research shows that the globalization of the clothing industry has a significant impact on both climate and society. Furthermore, consumers today demand sustainably produced products, and they are willing to pay more to support such companies. Despite this, research shows that there is a gap between consumers' expressed demand for sustainable alternatives and their purchasing behavior in favor of sustainable organizations . This gap is often referred to as the 'attitude-behaviour gap' (ABG), which refers to the gap between positive attitudes and consumer behavior. The purpose of this study is to explore the area described as the 'attitude-behaviour gap' between consumers' CSR requirements and purchasing behavior. Specifically, this phenomenon will be examined within the clothing industry with the help of the following questions: "Are Swedish consumers' sustainable attitudes transformed into purchasing behavior within the clothing industry?" if not; "Which factors possibly influence ABG in the Swedish clothing industry?". Method: The study has been based on a qualitative approach where interviews with consumers have been carried out. The interviews were conducted in a semi-structured manner and analyzed thematically based on an analysis model designed from previous research. Results: The study has confirmed that ABG also exists in Swedish consumers. The results show that negative CSR information damages the company's relationship with consumers and in many cases leads to a loss of customers. In contrast, positive CSR information is not as significant. For consumers to switch to sustainable consumption, certain core factors need to be met; first, the consumer needs to have sufficient information and a personal interest in CSR. The consumer's perception of price, the availability of sustainable alternatives and the attributes of the clothes are also central factors. In addition to this, peripheral factors can influence consumers' purchasing behavior. These factors have been explained as company image and credibility, peer pressure, and consumer familiarity. / Ämnet hållbar utveckling växer sig allt större i relevans och aldrig förr har forskning kring ämnet varit så väsentligt. Forskning visar på att globaliseringen av klädindustrin har en betydande påverkan på både klimat och samhälle. Vidare efterfrågar konsumenter idag hållbart producerade produkter och att de är villiga att betala mer för att stödja sådana företag. Trots detta så visar forskning att det finns ett glapp mellan konsumenters uttalade efterfrågan på hållbara alternativ och deras köpbeteende i förmån för hållbara organisationer. Detta gap benämns ofta som ‘attitude-behavior gap’ (ABG) som refererar till mellanrummet mellan de positiva attityderna och konsumenternas beteenden. Syftet med denna studie är att utforska området som beskrivits som ‘attitude-behavior gap’ mellan konsumenters CSR krav och köpbeteende. Specifikt kommer detta fenomenet att granskas inom klädindustrin med hjälp av följande frågeställningar:“Omvandlas svenska konsumenters hållbara attityder till köpbeteenden inom klädindustrin?” om inte; “Vilka faktorer påverkar eventuellt ABG i den svenska klädindustrin?”. Metod: Studien har utgått från ett kvalitativt tillvägagångssätt där intervjuer med konsumenter har genomförts. Intervjuerna genomfördes på ett semistrukturerat sätt och analyserades tematiskt baserat på en analysmodell som utformats från tidigare forskning. Resultat: Studien har bekräftat att ABG existerar även hos svenska konsumenter. Resultaten visar på att negativ CSR-information skadar företagets relation till konsumenterna och leder i många fall till en förlust av kunder. Däremot är inte positiv CSR-information lika betydande. För att konsumenterna ska övergå till hållbar konsumtion behöver vissa kärnfaktorer uppfyllas; dels behöver konsumenten ha tillräckligt med information och en personlig angelägenhet gentemot CSR. Centralt är även konsumentens prisuppfattning, de hållbara alternativens tillgänglighet och klädernas attribut. Utöver detta kan perifera faktorer påverka konsumenternas köpbeteenden. Dessa faktorer har förklarats som företagets image och trovärdighet, grupptryck, samt konsumentens familjaritet.

Magmatologie du Piton de la Fournaise (Ile de la Réunion) : approche volcanologique, pétrologique et expérimentale / Magmatic evolution of Piton de la Fournaise (La Réunion island)

Brugier, Yann-Aurélien 17 June 2016 (has links)
Afin de parvenir à une meilleure compréhension des processus d’évolution des magmas réunionnais, nous avons réalisé une étude ayant pour objectifs principaux : (1) la simulation expérimentale du système d’alimentation du Piton de la Fournaise, à partir d’un matériel de départ de composition typique de Steady State Basalt et dans des conditions de pression, température, fO2 et de teneurs en volatils (H2O, CO2) réalistes ; (2) la détermination de la séquence de cristallisation d’échantillons représentatifs des roches plutoniques réunionnaises de façon à les comparer avec les résultats expérimentaux et (3) l’obtention d’une base de données volcanologiques, pétrologiques et géochimiques significative sur le groupe de laves anormales (« Abnormal Group ») permettant de confirmer son existence dans le système d’alimentation du Piton de la Fournaise. La découverte de verres silicatés ayant des compositions caractéristiques de l’Abnormal Group confirme l’implication de ces magmas dans l’activité éruptive. Toutefois, les roches plutoniques n’enregistrent pour la plupart que des séquences de cristallisation témoignant d’une évolution superficielle des magmas. Cette dernière est simulée de façon satisfaisante par les expérimentations réalisées dans la gamme 0.1 à 50 MPa qui conduisent à des modèles pétrologiques et des pressions de stockage en accord avec les données géophysiques. Les expérimentations à plus forte pression démontrent l’existence de paliers au sein du système d’alimentation qui peuvent en grande partie expliquer les diverses compositions réunionnaises, mais posent la question de la composition des magmas parentaux. / To better understand magmatic processes associated with the evolution of La Réunion magmas, we have carried out a multi-approach study aimed at (1) simulating experimentally the feeding system of the Piton de la Fournaise volcano, using a Steady State Basalt starting material and P-T-fO2-Volatiles (H2O, CO2) conditions compatible with the natural system; (2) determining crystallization sequences representative of La Réunion plutonic rocks for comparison with the experimental results and (3) constructing a volcanological, petrological and geochemical database for lavas of the Abnormal Group, to confirm the existence of Abnormal melts in the feeding system of the volcano. The discovery of glasses having chemical characteristics similar to the Abnormal Group establishes the implication of Abnormal melts in eruptive processes. However, plutonic rocks record crystallization sequences that for the most part indicate a low pressure magmatic evolution. Experiments in the pressure range 0.1 to 50 MPa satisfactorily reproduce conditions in the shallow magmatic systems and lead to petrological models and magma storage depths in agreement with geophysical data. Experiments at higher pressures demonstrate transitions in magma fractionation mechanisms in the feeding system that can explain the range of erupted compositions, but call into question the compositions of parental magmas.

Successful Treatment of Respiratory Insufficiency Due to Adult Acid Maltase Deficiency With Noninvasive Positive Pressure Ventilation

Puruckherr, Michael, Pooyan, Payam, Girish, Mirle R., Byrd, Ryland P., Roy, Thomas M. 01 July 2004 (has links)
Acid maltase deficiency (AMD) is a rare autosomal recessive genetic disorder that results in an accumulation of glycogen in the lysosomal storage vacuoles. It is classified as a glycogen storage disease (type II) and is also known as Pompe's disease. The prognosis of the patient with AMD is poor and the main cause of death is respiratory failure. We report a female patient whose respiratory insufficiency was documented to occur most severely during rapid eye movement sleep and who benefited clinically from the institution of nocturnal noninvasive bilevel positive airway pressure.
