    DR3 og det kreative pres

    Get PDF
    I denne afhandling undersøger jeg, hvilke strategiske tiltag tv-kanalen DR3 anvender for at tiltrække sin målgruppe (15-39 år), hvilken rolle digitalisering og idéudvikling spiller i kanalens tv-produktion, og hvilke forståelser af kreative processer kanalens ansatte benytter sig af. Motivationen bag afhandlingen er, at unge danskere i stigende grad forlader flow-tv-seningen til fordel for streaming, hvilket udgør et problem for bredden i DR’s public service-mandat, og digitaliseringen af tv-mediet kalder således på nye løsninger og nye kompetencer i tv-branchen. DR3’s løsning har derfor været at forsøge at appellere til målgruppen ved at eksperimentere med programmer og indhold til digitale platforme.I denne sammenhæng har jeg interesseret mig for, hvad DR3’s kanalstrategi reelt set er, og i hvilken grad denne strategi skaber et kreativt pres, som påvirker kanalens programproduktion og idéudvikling. For at undersøge dette empirisk har jeg i perioden 2016-2019 foretaget en række kvalitative forskningsinterviews med redaktører og freelancere på DR3 og DR Ung, lavet etnografiske observationer af DR3/DR Ungs idéudviklingsprocesser og lavet en kvantitativ indholdsanalyse af DR3’s programudbud fra 2013-2017.Teoretisk set trækker afhandlingen på forskning i henholdsvis tv-produktion og kreativitet, og undervejs giver den sit bud på, hvordan disse to teoriområder kan kombineres, hvordan undersøgelser af kreativitet i tv-produktion kan konceptualiseres og operationaliseres i konkrete analyser, og hvordan et fokus på kreativitet kræver en række metodiske overvejelser. Grundet en mangel på teorier om kreativitet i tv har jeg inddraget kreativitetsforståelser fra andre teorifelter, og særligt den socialkonstruktivistiske tilgang til kreativitet som fænomen samt en række teorier om idéudvikling og gatekeepere har været nyttige analyseværktøjer.På grund af afhandlingens artikelbaserede format består den af fire produktionsanalytiske artikler om henholdsvis DR3’s kanalstrategi, produktionen af DR3-serien Anton 90, tilgangen til ungdomsfiktion hos DR3 og DR Ung samt brugen af forskellige evalueringsregimer i deres idéudviklingsprocesser. Analyserne påviser blandt andet, hvordan DR3 har udviklet sig og ændret sin kanalstrategi siden kanalens opstart i 2013, men også kontinuiteten i kanalens programproduktion, og hvordan kanalen kontinuerligt har leveret nye programkoncepter inden for nogle specifikke genrer og forsøgt at lave unikt public service-indhold til målgruppen.Afhandlingen bidrager samlet set med at tydeliggøre, hvordan tv-programmers kreative værdi er et ustabilt fænomen, og hvordan kreativitet i tv-produktion er et komplekst samspil mellem forskellige sociale mekanismer, hvor gatekeepende redaktører i DR3 og DR Ung spiller en vigtig rolle i evalueringen af, hvilke produkter og idéer der er ”kreative”. I DR3’s tilfælde sætter intentionen om at ville eksperimentere udviklerne under et kreativt pres, fordi de er vant til at navigere efter de gatekeepende redaktørers præferencer, som pludseligt tilsidesættes, når redaktørerne beder om eksperimentelle idéer. Dermed peger konklusionen på, hvordan det kreative pres kan være resultatet af en spænding eller antitese mellem branding (genkendelighed) og kreativitet (nyskabelse), som kanalen skal prioritere imellem. Hermed kan afhandlingen konkludere, at der er et kreativt pres til stede i idéudviklingen, som er præget af kanalens intention om at eksperimentere, af et simplicitetsregime i udviklingsprocessen, af en lav succesrate for nye idéer samt af ændrede markedsvilkår som en konsekvens af tv-mediets digitale forandringsproces. Min afhandling udfordrer dermed visse forestillinger om autonomi i medieindustrier og fremhæver, hvordan kreativitet ikke kun kan beskrives som en positiv og mystisk skabelseskraft, men at det også kan fungere som et pres i produktionsprocesser, og at disse resultater kalder på flere empiriske undersøgelser af idéudvikling og kreativitet i tv-produktion

    Probing electric and magnetic vacuum fluctuations with quantum dots

    Full text link
    The electromagnetic-vacuum-field fluctuations are intimately linked to the process of spontaneous emission of light. Atomic emitters cannot probe electric- and magnetic-field fluctuations simultaneously because electric and magnetic transitions correspond to different selection rules. In this paper we show that semiconductor quantum dots are fundamentally different and are capable of mediating electric-dipole, magnetic-dipole, and electric-quadrupole transitions on a single electronic resonance. As a consequence, quantum dots can probe electric and magnetic fields simultaneously and can thus be applied for sensing the electromagnetic environment of complex photonic nanostructures. Our study opens the prospect of interfacing quantum dots with optical metamaterials for tailoring the electric and magnetic light-matter interaction at the single-emitter level.Comment: 6 pages, 4 figure

    The Creation of BugBag. Redesign of Insect Trap for Biological Pest Control

    Get PDF
    Introduction The project is based on research on pheromones and the project SoftPest Multitrap. Copenhagen Universitys Science and Life Sciences, more specifically Department of Plant and Environmental Sciences, has researched and developed the pheromonis for mass trapping of the Strawberry Blossom Weevil (Anthonomus Rubi) and the European Tarnished Plant Bug (Lygus Rugulipennis). Our foucus is on the user-experience Associated with the pheromonibased traps. Especially the distrubution, assembly, setup, Collection, cleaning, storage and The Problem The Strawberry Blossom Weevil and European Tarnished Plant Bug are a major problem to European strawberry producers and reduces the annual yield remarkably. The conventional strawberry producers can efficiently spray with pesticides to control the pest, however, this is harmful to the environment. The ecological strawberry producers lack effective pest control methods and has no options if they are attacked by the mentioned pest. A preromone-based pest control method is a promising alternative and it is useful for both conventional and ecological strawberry producers. However, a userdriven redesign of SoftPest Multitrap (figure 1) is nescessary. This is to ensure that the traps can be easily implemented in the various production methods and be a competitive alternative to pesticides

    Therapeutic Cancer Vaccines in Combination with Conventional Therapy

    The clinical efficacy of most therapeutic vaccines against cancer has not yet met its promise. Data are emerging that strongly support the notion that combining immunotherapy with conventional therapies, for example, radiation and chemotherapy may improve efficacy. In particular combination with chemotherapy may lead to improved clinical efficacy by clearing suppressor cells, reboot of the immune system, by rendering tumor cells more susceptible to immune mediated killing, or by activation of cells of the immune system. In addition, a range of tumor antigens have been characterized to allow targeting of proteins coupled to intrinsic properties of cancer cells. For example, proteins associated with drug resistance can be targeted, and form ideal target structures for use in combination with chemotherapy for killing of surviving drug resistant cancer cells. Proteins associated with the malignant phenotype can be targeted to specifically target cancer cells, but proteins targeted by immunotherapy may also simultaneously target cancer cells as well as suppressive cells in the tumor stroma

    Cultural capital in context: Heterogeneous returns to cultural capital across schooling environments

    Get PDF
    AbstractThis paper tests two competing explanations of differences in returns to cultural capital across schooling environments: Cultural reproduction (cultural capital yields a higher returns in high-achieving environments than in low-achieving ones) and cultural mobility (cultural capital yields higher returns in low-achieving environments). Using multilevel mixture models, empirical results from analyses based on PISA data from three countries (Canada, Germany, and Sweden) show that returns to cultural capital tend to be higher in low-achieving schooling environments than in high-achieving ones. These results principally support the cultural mobility explanation and suggest that research should pay explicit attention to the institutional contexts in which cultural capital is converted into educational success

    This report describes the working processes and results of the bachelor project “Redesign of insect trap for biological pest control”. The project is based on research on pheromones and the project SoftPest Multitrap. Copenhagen Uni-versity’s Science and Life Sciences, more specifically Department of Plant andEnvironmental Sciences has researched and developed the pheromones for mass trapping of the Strawberry Blossom Weevil (Anthonomus Rubi) and the European Tarnished Plant Bug (Lygus Rugulipennis). The user processes associated with the insect trap were analysed through fieldstudies and a participatory design process. The analysis resulted in a design brief and a product specification.The SoftPest Multitrap proved to be difficult toimplement in the various strawberry production methods, uncompetitive with the existing insecticides on the market. Ineffective through the use processes; assem-bly, setting up and maintenance. The developed concept supports compact distribution, easy assembly and setting up in the various strawberry productions regardless of wind, weather and soil con-ditions. The strawberry producers can remain indifferent to the trap through the pest season and traps are effectively collected, easily cleaned and stored for next year. An estimated calculation of production costs for respectively prototype- and mass production of the trap was prepared. In continuation of the estimated cost of production, the trap’s competitiveness relative to pesticides was studied through various scenarios. The conclusion is that the trap is competitive if the use of pesticides results in a subsequent outbreak of spider mites. A CAD process enabled the development of a functional prototype for later testing in a strawberry production
