Syftet med den här uppsatsen är att ta reda på vilka faktorer och risker som påverkar köpbeslutet för en konsument gällande en ny innovativ produkt. Uppsatsen kan på så sätt bidra med kunskap och förståelse för företag som vill utveckla den här typen av produkter. Studiens inriktning och syfte togs fram i samarbete med textilföretaget FOV Fabrics. Med utgångspunkt ur syftet och problemet genomfördes en enkätundersökning som kompletterades med semi-strukturerade intervjuer med fyra av enkätrespondenterna. Resultatet av enkätundersökningen analyserades och jämfördes med resultatet av intervjuerna. Enkät- och intervjurespondenterna delades in i två grupper, adoptörer och icke-adoptörer, baserat på om de valt att adoptera produkten i fråga eller ej. Grupperna analyserades och jämfördes för att få en förståelse för varför konsumenter adopterar nya produkter och varför vissa inte gör det. Studien visade att adoptering av nya produkter inte kan göras konkret för produkter överlag, då processen skiljer sig bland produktkategorier. Den här studien visar endast hur köpbeslutsprocessen för specifikt en skjorta i funktionsmaterial kan gå till, vilket även kan gälla för andra plagg med samma material men inte för andra produktkategorier. Studien visade på att adoptörer, bestående av innovators och early adopters, är främst mottagliga för nya innovationer. De består av tekniska, funktionsorienterade individer. Förutom funktionerna skjortan erbjuder (vattenavvisande, smutsavvisande, strykfri, antibakteriell) värderar de passform, komfort och design i ett plagg. Det är innovatörerna som bör adoptera produkten för att produkten ska kunna accepteras av majoriteten av konsumenterna. För att en adoption ska kunna ske av mer skeptiska konsumenter är det viktigt med tillförlitlighet och ett varumärke konsumenten kan lita på, om inte informationen och kunskapen om produkten är tillräcklig. / The purpose of this paper is to find the different factors and risks that affect the buying decision for a consumer when being faced with an innovative product. The study can contribute with knowledge and an understanding for companies that are looking to develop this type of products. The focus and purpose was developed in cooperation with the textile company FOV Fabrics. With the purpose and the problematics as a basis, a survey was completed alongside semi-structured interviews with four of the respondents from the survey. The result from the survey was analyzed and compared with the results from the interviews. All of the respondents were divided into two groups, adopters and non-adopters, based on if they wanted to adopt the product in question or not. The two groups were analyzed and compared to reach an understanding to why consumers choose to adopt new products and why some of them do not. The study showed that adoption of new products is not something that can be defined for all products, as the process differentiates between product categories. This study only shows what the buying decision process looks like for a shirt made of functional material, which can be translated to another garment with the same material, but not through other product categories. The study also showed that the adopters are consisting of innovators and early adopters, which are most receptive to new innovations. They are technical, function- oriented individuals. Besides the functions in the shirt (water repellant, stain resistant, non-iron, anti-bacterial) they value fit, comfort and design in garments. The innovators should adopt the product so it can be accepted by the majority of the consumers later on. To achieve an adoption by the skeptical consumers, reliability is an important factor and a brand that the consumer can trust, if the knowledge and information about the product is not sufficient enough. Please note that the paper is written in Swedish.

Die vorliegende Ausgabe untersucht theoretische und empirische Ergebnisse zu Hemmnissen in Entscheidungsprozessen in Organisationen. Zu Beginn steht die Aufarbeitung der Theorie zum Hemmnisbegriff anhand folgender Forschungsfragen: Wie wird der Hemmnisbegriff definiert? Welche Wörter werden synonym verwendet? Wie entstehen Hemmnisse? Was gibt es für Methoden zur Messung und Bewertung von Hemmnissen? Ausgehend von diesen theoretischen Betrachtungen erfolgt eine Zusammenschau von 104 empirischen Studien zu Hemmnissen in Entscheidungsprozessen unter der Fragestellung: Was gibt es für empirische Studien zu diesem Thema? Wie unterschieden sich diese bzw. wie lassen sie sich charakterisieren und systematisieren? Dabei werden der Hintergrund der Studien (Land, Branche, Ent-scheidungsprozess, Befragte), ihre Methodik, die Methodik der Hemmnisanalyse, der Hemmnisbegriff und die Entstehungsfaktoren betrachtet. Zur Systematisierung der Studien werden Gruppierungsansätze nach einzelnen Merkmalen (Veröffentlichungsjahrzehnt, Kontinent, Entwicklungsniveau des untersuchten Landes, Branche, Entscheidungsprozess, Studienmethodik) und eine Clusteranalyse über 49 Variablen durchgeführt. Die Gruppierungsansätze werden mittels ihrer Aussagekraft zum Entscheidungsprozess, zur Hemmnismethodik und zu den Entstehungsfaktoren von Hemmnissen beurteilt. Die Aufschlüsselung nach Entscheidungsprozessen erscheint als empfehlenswert. Die Ergebnisse der Clusteranalyse lassen darauf schließen, dass sich die Studien relativ ähnlich sind. Zusammenfassend gibt es keine allgemeingültige First-Best-Lösung zur Systematisierung der Studien. Die Gruppierungsansätze bewegen sich im Spannungsdreieck, möglichst von der Größe her vergleichbare aber vom Inhalt her unterscheidbare Studiengruppen zu bilden und dabei alle Studien in die Gruppierung einzubeziehen. Der zu wählende Gruppierungsansatz ist davon abhängig, welche Forschungsfragen im Vordergrund der jeweiligen Untersuchung stehen.

Gestalt theory and Positive Psychology formed the underlying theoretical frameworks of this study. Both Gestalt theory and Positive Psychology adopt a positive outlook towards human nature with the possibility of individuals becoming self-supporting and fully functioning. Both theories also regard awareness to be paramount in establishing healthy self-regulation and optimal well-being. Both Gestalt theory and Positive Psychology provided the link between the concepts, and were also used to describe the main concepts in the study. A review of the literature shows that children living in underprivileged communities often face many environmental stressors that can impact on their well-being and optimal psychological, cognitive, emotional and physical functioning. When this occurs, children are often not able to meet very important needs. They may have to find alternative ways to „survive‟ and protect themselves from certain stressors and cope with their environment. Very often these coping strategies are dysfunctional and certain parts within the child can become cut off or pushed aside, severing healthy contact with the environment. The child may also experience a sense of numbing and lack of awareness of senses, emotions and thoughts. The child is therefore living out of awareness. The literature suggests that the process of artmaking can contribute to facilitating awareness, which can enhance selfunderstanding and possibly lead to a greater sense of well-being. The researcher attempted to explore the kinds of awareness that could be facilitated through the artmaking process. A qualitative research design with a phenomenological strategy of enquiry was used for this study. Seven children in middle childhood living in a low socio-economic community took part in the study. They were between the ages of eleven and twelve years and had suffered some form of environmental stress. They had been subjected to substance and alcohol abuse, violence, death and divorce. Focus groups and semi-structured interviews were used in order to understand what awareness may have been facilitated in children during the art-making process. The data collected were analysed thematically. The results revealed that the art-making process enabled the participants to experience certain kinds of awareness. The participants became aware of certain emotions and feelings like happiness, enjoyment, calmness, pride and mastery, as well as feelings of anger, sadness and denial. The participants were able to recognise and express positive emotions, but it appeared that the more complex emotions were recognised although not expressed. The most common emotion experienced by the participants was the sense of happiness and enjoyment they seemed to feel as they worked with the different art materials. It appeared that the playful nature of the art-making process kept them engaged and in contact with the process. The participants also became aware of a range of tactile experiences that each art medium offered; clay, paint, collage, hand printing and texture rubbings. These tactile experiences led them to an awareness of feelings and associations. The findings also indicated that the participants became aware of a sense of agency, as they appeared to have a sense of control and empowerment over the art mediums. This element of control over the art mediums seemed to afford the participants the ability to change what they did not like in their art work. This ability to change things appeared to feed back to, and enhance, their sense of empowerment. Through the findings of the study, as well as from the literature, this quality of empowerment, control and change is important for children in need living in a stressful environment, as it may foster a sense of agency that they may not find from their environment. Another significant finding seemed to be the participants‟ awareness of their context in terms of an unavailability of certain environmental resources to fulfil their needs, namely financial resources and nurturing. The participants‟ awareness centred around basic survival needs, for example lack of sufficient food, but also their awareness of relational needs and challenges, for example overcrowded households, alcohol-abusing parents and divorce. / Thesis (MA (Psychology))--North-West University, Potchefstroom Campus, 2013.

The contact-making process of teachers with learners, who present with sensory processing disorder (SPD), has an impact on the learners’ functioning in the classroom. In this study the researcher explored how teachers made contact with these learners by using their senses to accommodate the learners’ unique contact-making style. The involved occupational therapists selected teachers, who taught learners who received occupational therapy for SPD in the age group 7-12 years. The selected teachers participated in unstructured interviews. The case study was used as research method and aimed at gaining deeper insight into and understanding of the teachers’ understanding of and contact-making process with learners with SPD. Erikson’s developmental theory was integrated with the Gestalt theoretical perspective, with focus on the relevant age group. The researcher became aware of contact-making interruptions that occurred during the contact- making process between the teachers and learners with SPD. These interruptions occurred because the teachers did not fully understand the contact-making processes and needs of the learners with SPD. The mentioned contact-making interruptions may occur in various forms. The contact-making interruptions were used by the learners to protect themselves and for organismic self-regulation. During the unstructured interviews the teachers became aware of the importance of the way that they made contact with learners who present with SPD, but they lacked training in the appropriate teaching techniques. The results indicated that teachers needed knowledge about SPD and skills to facilitate and accommodate learners with SPD and to approach them according to their uniqueness. Recommendations were formulated to enhance the teachers’ knowledge about SPD and support the teachers to try other strategies in the classroom to improve the contact-making process with learners who present with SPD. The recommendations made by the researcher were done in support of teachers in order to make sufficient contact with learners who present with SPD, and in doing so, to promote the holistic development of these learners. It is important that teachers are aware of the possible contact-making interruptions used by learners who present with SPD, in order to creatively adjust their own contact-making process and to retry to make and maintain good contact with involved learners by using different senses. This study is a first step in more effective service rendering to learners with SPD, by clarifying issues and shedding light on how teachers cope with this challenge. / Thesis (MA (Psychology))--North-West University, Potchefstroom Campus, 2013.

In view of the latest corporate collapses globally, the purpose of this thesis is an attempt to investigate and to theorise how managers make decisions when faced with an ethical dilemma.Philosophers over the years have proposed different moral theories. For example, Kantian’s Categorical Imperative (O’Neil 2001, Peters, 1971) suggests that there are laws that should apply universally. However, its principles are too abstract to guide action, in that it does not provide a detailed set of instructions for following them. Others such as Baier, (2001) suggest that people behave to satisfy their own self-interest. The literature review shows that there is no consensus to define what constitutes ethical behaviour. Kohlberg (1981) divides childhood moral development into six stages. He theorises that greater moral development will be related to the highest social responsibility of an individual. Lagon (2000), Seabright and Moberg (1998), Logsdon and Yuthas (1997) extrapolate Kohlberg’s model to incorporate into organisational and individual moral development.Based on the literature review, research questions were developed. The research methodology is qualitative, based on the realism paradigm using a case research design (Yin 1994). Face to face interviews were conducted with fourteen participants using critical incidents and the findings were triangulated using a semi-structured focus group.The research data analysis is based on grounded theory proposed by Glaser and Strauss (1967). The findings confirm that there is no single theory or approach to business ethics. The findings indicate that a person’s ethical behaviour changes when his/her self-interest is affected. Whilst participants believed that business and ethics can be reconciled, most agreed that they can only be reconciled if the individual’s interest or business profit is not affected. Based on the findings, a new model is proposed in an attempt to theorise an individual’s business ethical behaviour and his/her ethical decision making process.This research also identifies important areas that require further research. These are:• Conflicts between personal values and business values• Should ethics be taught? And if so how?• Should an ethical programme be developed and incorporated in a company’s strategic plan?

Η παρούσα διατριβή έχει στόχο τη διερεύνηση της επίδρασης της νέας ιατρικής τεχνολογίας στην αποτελεσματικότητα παραγωγής των Μονάδων Εντατικής Θεραπείας (ΜΕΘ) στην Ελλάδα, καθώς και τον εντοπισμό των στοιχείων που επηρεάζουν τη διαδικασία λήψης αποφάσεων στο πλαίσιο του Εθνικού Συστήματος Υγείας (ΕΣΥ) για την υιοθέτηση ιατρικής τεχνολογίας. Για την εκτίμηση της αποτελεσματικότητας κάθε μονάδας, εφαρμόζεται η τεχνική bootstrapped DEA των Simar και Wilson (2007), ενώ για την διερεύνηση των στοιχείων που οδηγούν στην απόφαση υιοθέτησης γίνεται χρήση υποδειγμάτων probit. Κατόπιν, με τη χρήση υποδειγμάτων επιβίωσης εντοπίζονται οι παράγοντες που κατηγοριοποιούν τις Νοσοκομειακές μονάδες αναφορικά με το χρόνο υιοθέτησης. Ο αξονικός τομογράφος στα δημόσια νοσοκομεία χρησιμοποιείται σαν μελέτη περίπτωσης. Η μελέτη κατέδειξε ελλείμματα τόσο στην τεχνική αποτελεσματικότητα όσο και στην αποτελεσματικότητα κλίμακας στις περισσότερες μονάδες που εξετάστηκαν, κυρίως λόγω έλλειψης νοσηλευτικού προσωπικού. Τα αποτελέσματα δείχνουν ότι αν και η τεχνική αποτελεσματικότητα επωφελείται από την ενσωμάτωση των νέων ιατρικών τεχνολογιών, η αποτελεσματικότητα κλίμακας παραμένει ανεπηρέαστη. Αναφορικά με το την πιθανότητα και το χρόνο υιοθέτησης, διαπιστώθηκε ότι το μέγεθος του νοσοκομείου και η πληρότητα επιδρούν θετικά. Τέλος, τα συμπεράσματα επεξηγούν το βαθμό στον οποίο η υιοθέτηση νέας τεχνολογίας επηρεάζει τόσο την αποτελεσματικότητα των Νοσοκομειακών μονάδων γενικότερα, όσο και τη διαδικασία λήψης σχετικών αποφάσεων. Η παρούσα Διατριβή συμβάλλει στην γενικότερη ανάπτυξη της αποτελεσματικότητας του Συστήματος Υγείας και στην προώθηση του διαλόγου μεταξύ των εμπλεκόμενων στα θέματα διοίκησης και διαχείρισης του Συστήματος Υγείας. / This thesis aims to investigate the effect of new medical technology on the production efficiency of Intensive Care Units (ICUs) in Greece and unravel the elements which influence the decision making process concerning the adoption of new medical technologies in the context of the Greek Health System. In order to evaluate the efficiency of each Unit, the bootstrapped DEA of Simar and Wilson (2007) is applied, while a probit model is used for exploring the elements that lead to the adoption decision. Then, the factors that categorize hospitals regarding the timing of adoption are identified through the use of survival models. Computerized tomography in the Greek public sector is used as a case study. The study demonstrated deficits in both technical and scale efficiency in most Units, mainly due to lack of nursing staff. The results show that while technical efficiency has benefited from new medical technology integration, the scale efficiency remains unaffected. With respect to the likelihood and the time of adoption, it was found that the hospital’s size and plenitude have positive impact. Finally, the findings explain the extent to which health technology adoption affects both the hospital’s efficiency and the decision-making process. The present thesis contributes to the overall increase of the Health System efficiency as well as in promoting the dialogue between health administrators.
