To ensure that a customer is satisfied when they purchase a product, they need to be able toreceive assistance if the product does not work correctly or is in any other way unsatisfactory. Thisis why support is needed. There are many different types of support, but with an ever growingnumber of people having less time to spare in their every day life, a quick short answer issometimes preferred. This is why the market for Live-Chat support solutions has grown.    The purpose of this thesis project is to develop a functional stand-alone Live-Chatdemonstration prototype according to Askås' demands and wishes. The demonstration prototypewas developed using the programming language Perl, with additional functionality developed injQuery, HTML and CSS. The project will be evaluated by its functionality and too which degree itcompares to similar solutions.    The project was successful in the development of a functional demonstration prototypehowever further development is needed if it is to be used as a complement to Askås' web-shopsolution.

Background：Live streaming shopping is becoming a mainstream method in China since the livestreaming feature has been applied to e-commerce. Live streaming commerce reflects theinterdependence between consumers and live streamers. Past studies have found that the ability,social presence and reputation of live streamers influence consumers' purchase intentions.However, there is a gap in how consumers' purchase intentions are affected by negative incidentsand a lack of qualitative perspective. Purpose：To explore consumers' understanding of their purchase intentions in relation to liveshopping streamers, in the context of negative incidents with streamers. Methodology：This study used qualitative research as the research method and abductivereasoning to conduct the data analysis. This study used semi-structured interviews and developedinterview questions based on the content of the theory chapter. The researchers usednon-probability sampling and general purpose sampling as the sampling strategy. The requireddata were obtained from 12 Chinese interviewees who had experience with live shopping. Theobtained data were then coded using grounded theory as the analysis method for qualitative data,which helped the researchers understand the thoughts of the interviewees. The final attempt is todevelop a theory that can explain the phenomenon. Moreover, the methods chapter explores thequality of the research in this study, as well as possible ethical and social issues. Findings：This paper identified three consumer needs (utilitarian, pleasure-seeking andemotional needs) and factors associated with streamers (attitude, streaming style, impact,characteristics and ability) that influence purchase intentions in the presence of negative streamerincidents. The paper also found how consumers' purchase intentions were influenced by thesefactors in different negative incident situations. Conclusion：This study obtained consumers' understanding of the relationship between theirpurchase intentions and streamers. Consumers exhibit three different levels of purchase3intention: willing to buy, wait-and-see (unsure of purchase intention) and no purchase intention.In the case of negative incidents, consumers' different purchase intentions are influenceddifferently by their own needs and streamer factors.

Severe malaria caused by Plasmodium falciparum (P. falciparum) remains a leading cause of death in many low and middle income countries. The intraerythrocytic reproduction cycle of the parasite is responsible for all the symptoms and mortality of malaria. The merozoite, first invade a red blood cell (RBC) in the circulation, then grows, develops and multiplies within it by clonal division. Merozoite invasion is a complex process involving dynamic interactions between ligands in the merozoite coat and receptors on the red blood cell membrane. Therefore, filming the complete malaria invasion processes may shed the light on its mechanism. The rationale of this work is that learning how the various ligand-receptor interactions affect invasion phenotypes will lead us to a better understanding of the key biological and biophysical aspects of parasite growth in the blood. The work described has firstly involved the development of an optimised imaging platform for recording egress-invasion sequences. I used live cell microscopy to understand this stage of malarial infection better, by monitoring egress-invasion sequences in live cultures under controlled conditions and addressing the morphology and kinetics of erythrocyte invasion by P. falciparum. In addition, the erythrocyte invasion phenotypes of the various P. falciparum strains were systematically investigated for the first time by live cell microscopy. Furthermore, to better understand genetic recombination affecting erythrocyte invasion phenotypes, progeny from the 7G8 x GB4 cross was compared to their parents. In order to investigate specific receptor-ligand interactions and their distinct functional characterisations at each distinct stage, the enzymes that cleave receptors on the erythrocytes and antibodies targeting ligands on the merozoites were studied and their effects observed using the live-imaging platform. In the results, the functions of ligands on the merozoites demonstrated for the first time distinct and sequential functions of proteins during erythrocyte invasion, which could potentially guide the design of more effective malaria vaccines. In addition, I have designed microfluidic devices for studying blood stage malaria. Polydimethylsiloxane (PDMS) microfluidic devices are optically transparent, non-toxic and have biocompatible features. Building on previous work, I made specific microfluidic devices for achieving a high throughput of egress-invasion observations. Infected red blood cells were delivered into a microfluidic device channel containing cage-like "nests". The nests were designed to selectively trap these stiff, egress-ready cells, in order to obtain streams of merozoites on maturation. Uninfected RBCs were delivered from another input into a long serpentine channel co-flowing with the egressed merozoites. The results indicated that, during P. falciparum erythrocyte invasion under flow conditions, the morphological effect on erythrocytes and the kinetic properties show significant differences to those in static conditions. In addition, with optimised flow rates, it is possible to reach higher throughput of egress-invasion observations than static conditions. Both the static and flow experiments carried out in this study highlight important mechanisms and processes of malaria invasion, and represent new ways of studying blood stage malaria. Precise and high throughout recording of single-event host-pathogen interaction events will allow us to address a new area of fundamental biological questions in future work.

<p>Programming is a very complex activity that has many simultaneous learning elements. The area of Live-programming offers possibilities for enhancing programming work by speeding up the feedback loop and providing means for reducing the cognitive load on the working memory during the task. This could allow for better education for novice programmers. In this work a number of systems with a shared aim of providing educational tools for scholars from compulsory level to undergraduate college were studied. The common approach in the majority of the tools was to use program abstractions like tangible morphs, playing cards, capsules for code segments, and visual stories. For the user these abstractions and tools offer better focus on the constructive and creative side of programming because they relieve the user from the cumbersome work of writing program code, but they also sacrifice some of the expressiveness of a low-level language.</p><p>A Live programming system, called PyMorphic, based on the Morphic model was built in the Python programming language. Two different solutions, based on the Wx toolkit for Python, were constructed and evaluated. The results show that Morphic and Python go well together because Python is a programming language that allows for compact and dynamic code. PyMorphic was evaluated with the cognitive dimensions framework and theories on cognitive load and working memory. A user attitude test was performed and the results showed that the users had a positive attitude towards the PyMorphic system.</p><p>The PyMorphic project is open-source and it is hosted on Sourceforge. The code can be downloaded from the project web-site: http://pymorphic.sourceforge.net. Anyone is welcome to take part in further development of PyMorphic.</p>

Denna uppsats syftar främst till att förstå hur en artist skapar en god upplevelse och de tillvägagångssätt som finns för att skapa den. Vi vill även påvisa att ett liveframträdande inte enbart är en tjänsteproduktion utan hur det även kan användas för att marknadsföra artistens varumärke och vilka konsekvenser detta får för varumärket.

This dissertation examines the repertoire for solo trumpet and electronics through a study of the genre as a whole and discussions of four compositions that represent its main stylistic approaches. An obscure but fascinating genre, current research in this area is limited to discussions of a few of its compositions in other dissertations and lecture recitals. By investigating this music, this dissertation will contribute to an area that has so far seen little research while promoting new repertoire that greatly expands the musical possibilities of solo trumpet performance. Based on the List of Compositions for Solo Trumpet and Electronics compiled by the author, several aspects of this repertoire are described in Chapter Two, including its development from 1965 to 2009 and the relative popularity of its different compositional approaches. The primarily academic background of this repertoire’s composers is discussed as well as the diverse nationalities they represent. The relative obscurity of this repertoire is suggested by the number of compositions for solo trumpet and electronics that have been published and recorded. A discussion of the aesthetic, qualitative and practical aspects of the repertoire is presented in Chapter Three. Based on interviews with leading performers of this repertoire and the composers of the pieces examined in this dissertation, this music is discussed from the perspective of musicians who have significant experience in this field. Their interviews illuminate several important issues that may not be apparent to musicians who are unfamiliar with this repertoire. Chapters Four through Seven discuss four representative compositions from the List. An overview of each piece is given, along with biographical information about its composer, a description of its electronic components, discussion of relevant performance techniques, and formal analysis of the composition. Conclusions based on this investigation and suggestions for future research are suggested in Chapter Eight.
