The outcome of an audience study supports theories stating that stories are a primary means by which we make sense of our experiences over time. Empirical examples of narrative impact are presented in which specific fiction film scenes condense spectators' lives, identities and beliefs. One conclusion is that spectators test the emotional realism of the narative for greater significance, connecting diegetic fiction experiences with their extra-diegetic world in their quest for meaning, self and identity. The 'banal' notion of the mediatization of religion theory is questioned as unsatisfactory in the theoretical context of individualized meaning-making processes. As a semantically negatively charged concept, it is problematic when analyzing empirical examples of spectators' use of fictional narratives, especially when trying to characterize the idiosyncratic and complex interplay between spectators' fiction emotions and their testing of mediated narratives in an exercise to find moral significance in extra-filmic life. Instead vernacular meaning-making is proposed.

The Pacific nation of the Independent Samoa (formerly Western Samoa) is not known for having a developed film industry. In 2011, a Samoan languge film called The Orator (O le Tulafale) placed the spotlight on Samoa, its people, and the Samoan culture when it became the country’s first ever film to be accepted into major international film festivals such as the 68th Venice Film Festival. Samoans the world over have embraced the film for its richness, compassion, and authenticity. Yet at times, the film portrays the Samoan culture as harsh and cruel. Samoans are usually quick to criticise negative portrayals of their culture but the thousands of comments on the film’s official Facebook page show otherwise. From April 2011 to March 2012, there were only 11 comments criticising the film on Facebook, and these criticisms were denounced as ‘un-Samoan’. This raised the question as to why Samoans did not react to the unflattering portrayals of their culture, but instead react against legitimate criticisms of the film. By using Foucault’s concept of heterotopia and the Samoan narrative structure of fāgogo, a heterotopia space and a utopia space are created in which past memories confirming Samoan cultural identity and bonds to the culture are evoked and are (re)experienced by Samoans while viewing the film. Thus the film’s ability to encourage this is what Samoans praise rather than the actual film.

Syftet med den här uppsatsen är att bidra med en djupare förståelse för hur musik påverkar uppfattningen av en karaktär i en film. Uppsatsen jämför resultaten från de som studerar inom ämnet musikproduktion med de som studerar inom ämnet bildproduktion på Högskolan Dalarna. Den undersökning som har bedrivits var av både kvantitativ och kvalitativ karaktär. Deltagarna i undersökningen har fått se en filmsekvens i tre olika versioner. Först utan musik, sedan med skräckmusik och avslutningsvis med spänningsmusik. Undersökningen är baserad på Johnny Wingstedts teorier om hur vi påverkas av musiken i vår vardag. Beroende på vilken musik de fick höra i samband med klippen så påverkades deras uppfattning av både karaktären samt handlingen i filmen.

Poly(styrene-co-methyl methacrylate) (PS-PMMA) ionomers with several degrees of sulfonation were synthesized and characterized by infrared, UV-vis, and NMR spectroscopies, elemental analysis, and differential scanning calorimetry (DSC). Stable Langmuir films could be produced with PS-PMMA with 3 and 6 mol % of sulfonation, while PS-PMMA 8% exhibited material loss to the water subphase, probably due to its higher solubility. Surface pressure and surface potential isotherms with PS-PMMA 3% spread onto salt-containing subphases pointed to a film behavior characteristic of the polyelectrolyte effect, where charge repulsion governs the film properties. The Langmuir-Blodgett films of this ionomer were successfully transferred onto various substrates, as confirmed by UV-vis and FTIR spectroscopies. Using cycling voltammetry, we show that LB films from PS-PMMA 3% can be applied in selective sensing of dopamine, even in the presence of interferents such as ascorbic acid.

Chitosan is alternated with sulfonated polystyrene (PSS) to build layer-by-layer (LBL) films that are used as sensing units in an electronic tongue. Using impedance spectroscopy as the principle method of detection, an array using chitosan/PSS LBL film and a bare gold electrode as the sensing units was capable of distinguishing the basic tastes - salty, sweet, bitter, and sour - to a concentration below the human threshold. The suitability of chitosan as a sensing material was confirmed by using this sensor to distinguish red wines according to their vintage, vineyard, and brands.

An oxovanadium-salen complex (NAP-ethylene-bis(salicylidenciminato) oxovanadium) thin film deposited on a graphite-polyurethane electrode was investigated with regard to its potential use for detection of L-dopa in flow injection system. The oxovanadium(IV)/oxovanadium(V) redox couple of the modified electrode was found to mediate the L-dopa oxidation before its use in the FIA system. Experimental parameters, such as pH of the carrier solution, flow rate, sample volume injection and probable interferents were investigated. Under the optimized FIA conditions, the amperometric signal was linearly dependent on the L-dopa concentration over the range 1.0 x 10(-1) to 1.0 x 10(-4) mol L-1 (I-anodic, mu A) = 0.01 + 0.25 [L-dopa mu mol L-1]) with a detection limit (S/N = 3) of 8.0 x 10(-7) mol L-1 and a sampling frequency of 90 h(-1) was achieved. For a concentration of 1.0 x 10(-5) mol L-1 L-dopa, the R.S.D. of nine consecutive measurements was 3.7%. (c) 2006 Elsevier B.V. All rights reserved.

The electrochemical preparation described herein involved the electrocatalytic oxidation of sulfite on a platinum electrode modified with nanostructured copper salen (salen=N,N'-ethylenebis(salicylideneiminato)) polymer films. The complex was prepared and electropolymerized at a platinum electrode in a 0.1 mol L-1 solution of tetrabutylammonium perchlorate in acetonitrile by cyclic voltammetry between 0 and 1.4V vs. SCE. After cycling the modified electrode in a 0.50 mol L-1 KCI solution, the estimated surface concentration was found to be equal to 2.2 x 10(-9) Mol cm(-2). This is a typical behavior of an electrode surface immobilized with a redox couple that can usually be considered as a reversible single-electron reduction/oxidation of the copper(II)/copper(III) couple. The potential peaks of the modified electrode in the electrolyte solution (aqueous) containing the different anions increase with the decrease of the ionic radius, demonstrating that the counter-ions influence the voltammetric behavior of the sensor. The potential peak was found to be linearly dependent upon the ratio [ionic charge]/[ionic radius]. The oxidation of the sulfite anion was performed at the platinum electrode at +0.9V vs. SCE. However, a significant decrease in the overpotential (+0.45V) was obtained while using the sensor, which minimized the effect of oxidizable interferences. A plot of the anodic current vs. the sulfite concentration for chronoamperometry (potential fixed = +0.45V) at the sensor was linear in the 4.0 x 10(-6) to 6.9 x 10(-5) mol L-1 concentration range and the concentration limit was 1.2 x 10(-6) mol L-1. The reaction order with respect to sulfite was determined by the slope of the logarithm of the current vs. the logarithm of the sulfite concentration. (C) 2009 Elsevier Ltd. All rights reserved.

An amperometric oxygen sensor based on a polymeric nickel-salen (salen = N,N'-ethylene bis(salicylideneiminato)) film coated platinum electrode was developed. The sensor was constructed by electropolymerization of nickel-salen complex at platinum electrode in acetonitrile/tetrabutylammonium perchlorate by cyclic voltammetry. The voltammetric behavior of the sensor was investigated in 0.5 mol L-1 KCl solution in the absence and presence of molecular oxygen. Thus, with the addition of oxygen to the solution, the increase of cathodic peak current (at -0.25 V vs. saturated calomel electrode (SCE)) of the modified electrode was observed. This result shows that the nickel-salen film on electrode surface promotes the reduction of oxygen. The reaction can be brought about electrochemically, where the nickel(II) complex is first reduced to a nickel(I) complex at the electrode surface. The nickel(I) complex then undergoes a catalytic oxidation by the molecular oxygen in solution back to the nickel(II) complex, which can then be electrochemically re-reduced to produce an enhancement of the cathodic current. The Tafel plot analyses have been used to elucidate the kinetics and mechanism of the oxygen reduction. A plot of the cathodic current vs. the dissolved oxygen concentration for chronoamperometry (fixed potential = -0.25 V vs. SCE) at the sensor was linear in the 3.95-9.20 mg L-1 concentration range and the concentration limit was 0.17 mg L-1 O-2. The proposed electrode is useful for the quality control and routine analysis of dissolved oxygen in commercial samples and environmental water. The results obtained for the levels of dissolved oxygen are in agreement with the results obtained with a commercial O-2 sensor. (C) 2012 Elsevier B.V. All rights reserved.
