There is increasing concern that the intensification of dairy production reduces the concentrations of nutritionally desirable compounds in milk. This study therefore compared important quality parameters (protein and fatty acid profiles; α-tocopherol and carotenoid concentrations) in milk from four dairy systems with contrasting production intensities (in terms of feeding regimens and milking systems). The concentrations of several nutritionally desirable compounds (β-lactoglobulin, omega-3 fatty acids, omega-3/omega-6 ratio, conjugated linoleic acid c9t11, and/or carotenoids) decreased with increasing feeding intensity (organic outdoor ≥ conventional outdoor ≥ conventional indoors). Milking system intensification (use of robotic milking parlors) had a more limited effect on milk composition, but increased mastitis incidence. Multivariate analyses indicated that differences in milk quality were mainly linked to contrasting feeding regimens and that milking system and breed choice also contributed to differences in milk composition between production systems.
The effects of dairy management and processing on quality characteristics of milk and dairy products
Resumo:
Studies within the QLIF project reviewed in this article suggest that organic or low-input management is more likely to result in milk with fatty acid profiles that are higher in α-linolenic acid and/or beneficial isomers of conjugated linoleic acid and antioxidants with up to a 2.5-fold increase in some cases, relative to milk from conventional production. These advantages are preserved during processing, resulting in elevated contents or concentrations of these constituents in processed dairy products of organic or low input origin. Much of the literature suggests that these benefits are very likely to be a result of a greater reliance on forages in the dairy diets (especially grazed grass). Since the adoption of alternative breeds or crosses is often an integral part sustaining these low-input systems, it is not possible to rule out an interaction with genotype in these monitored herds. The results suggest that milk fat composition with respect to human health can be optimized by exploiting grazing in the diet of dairy cows. However, in many European regions this may not be possible due to extremes in temperature, soil moisture levels or both. In such cases milk quality can be maintained by the inclusion of oil seeds in the dairy diets.

The present longitudinal study examines the interaction of learner variables (gender, motivation, self-efficacy and first language literacy) and their influence on second language learning outcomes. The study follows English learners of French from Year 5 in primary school (aged 9-10) to the first year in secondary school (Year 7 aged 11-12). Language outcomes were measured by two oral production tasks; a sentence repetition task and a photo description task both of which were administered at three time points. Longitudinal data on learner attitudes and motivation were collected via questionnaires. Teacher assessment data for general first language literacy attainment were also provided. The results show a great deal of variation in learner attitudes and outcomes and that there is a complex relationship between first language literacy, self-efficacy, gender and attainment. For example, in general, girls held more positive attitudes to boys and were more successful. However, the inclusion of first language ability, which explained 30-40% of variation, shows that gender differences in attitudes and outcomes are likely mediated by first language literacy and prior learning experience.

The reputation of The Phantom Carriage (Körkarlen) as one of the major films of Swedish silent cinema is in some respects securely established. Yet the film has attracted surprisingly little detailed discussion. It may be that its most striking stylistic features have deflected or discouraged closer scrutiny. Tom Gunning, for instance, in making the case for Sjöström’s Masterman, argues that ‘Körkarlen wears its technique on its sleeve, overtly displays its unquestionable mastery of superimposition and complex narrative structure. Mästerman tucks its mastery of editing and composition up its sleeve, so to speak’. This article makes an argument for a different evaluation of The Phantom Carriage, bringing a critical and interpretative understanding of the film’s style into conversation with the historical accounts of film form which predominate in the scholarship around silent cinema. It suggests that the film achieves ‘mastery of editing and composition’ with a flexibility and fluidity in the construction of dramatic space that is in itself remarkable for its period, but that Sjöström’s achievements extend well beyond his handling of film space. Specifically, it discusses a segment which is in several respects at the heart of the film: the first meeting between the two central characters, David Holm (Victor Sjöström) and Sister Edit (Astrid Holm); it spans the film’s exact mid-point; and at almost twelve and a half minutes it is the longest uninterrupted passage to take place in a single setting. The chapter argues that the dramatic and structural centrality of the hostel segment is paralleled by its remarkably rich articulation of the relationships between action, character and space. We show how Sjöström’s creation of a three-dimensional filmic space - with no hint of frontality - becomes the basis for a reciprocal relationship between spatial naturalism and performance style, and for a mise-en-scene that can take on discrete interpretive force. The argument also places the hostel sequences within the film as a whole in order to show how relationships articulated through the detailed decisions in this section take on their full resonance within patterns and motifs that develop across the film.
Motivational trajectories for early language learning across the primary-secondary school transition

The transition from primary to secondary school is an area of concern across a range of curriculum subjects, and this is no less so for foreign language learning. Indeed problems with transition have been identified in England as an important barrier to the introduction of language learning to the primary school curriculum, with implications for learners’ longer-term motivation for the subject. This longitudinal study investigated, through a questionnaire, the development of 233 learners’ motivation for learning French in England, during the transition from primary to secondary schooling. It also explored whether levels and patterns of motivation differed according to the type of language teaching experienced, comparing a largely oracy-focused approach with one with greater emphasis on literacy activities. Learners showed high and increasing levels of motivation across transition, placing particular value on learning French for travel. Being taught through an oracy or a literacy-focused approach had less impact on learners’ motivation than broader classroom experiences, with the development of a sense of progress and feeling that instruction met their learning needs being especially important. A growing disjuncture emerged between valuing the learning of French for travel/communication and learners’ low levels of self-efficacy for communication with native speakers, together with a desire for more communication-based activities. By the end of the first year of secondary school less positive attitudes towards learning French and less optimism about the possibility of future progress were beginning to emerge. The paper concludes by outlining the implications of the study for classroom practice in language learning.

Syftet med denna uppsats är att dels visa koleraepidemins utbredning i Alingsås år 1834 samt att kort jämföra den med omgivande städer i Västsverige och då framförallt Borås, och dels se på vilka återverkningar, upplevelser och reaktioner sjukdomen skapade hos människorna vid denna tid. De frågeställningar som har använts för att utveckla ovanstående syfte har varit: Vilka tankar, intryck och upplevelser gav sjukdomen upphov till? Vilka drabbades hårdast av sjukdomen? Hur förhåller sig dödstal, ålder, tidsdatering och social tillhörighet bland döda i en jämförelse med Borås? Vilka rykten, myter och reaktioner följde i kolerans spår? Materialet består av dödböcker och husförhörslängder för Alingsås stad och landsförsamling, protokoll från sundhetsnämnden i Alingsås landsförsamling, kungörelser och nedskrivna samtal från 1834, dagbok och anteckningar från privatpersoner från nämnda år samt litteratur och avhandlingar om Alingsås och koleran i Sverige. Alingsås stad hade vid sjukdomens inledningsskede en viss brist på läkare men detta avhjälptes snabbt och situationen var inte värre än i andra städer vid denna tid. För landsförsamlingen var dock bristen betydande. Då koleran härjade som värst upplevde människorna i Alingsås, liksom i många andra drabbade städer, en stark oro och ångest. De som oftast föll offer för koleran i Alingsås var fattiga som troligtvis på grund av trångboddhet och hygieniska svårigheter hade svårt att hålla smittan ifrån sig. I jämförelse med Borås visar Alingsås upp många likheter men också skillnader i form av fler döda och större dödlighet bland de fattiga.

Background: The background explains different financial crises and the effect those crises had on the Swedish acquits regarding variable compensation. The resent discussion regarding variable compensation and the main problems with bonuses is also explained. Our theories for this essay is mainly based on the new directions from Finansinspektionen FFFS 2009:6,7 and stakeholder theory. Other theories used are agency theory, stewardship theory and economic man.Purpose: The purpose of this essay is to analyze the new directions for variable compensation and to investigate if these new directions can lead to a more long-term thinking for managers in banks. Method:We used semi-structured interviews with open questions for our survey. During the survey we conducted three personal interviews and one mail interview, respondents represented the stakeholder groups: stakeholder, stakewatcher and stakekeeper. Conclusion: During our survey we found that the directions from Finansinspektionen are still on an early stage and it has been hard to analyze their effects. But it has been shown that the banks experience some difficulty in identifying their risk takers. In our investigation we have found that the new directions can be a step towards a more long-term thinking but it requires the management to change the point of view regarding bonuses.

Syfte: Syftet med denna studie var att beskriva uppfattningen hos sjuksköterskor med tjänst på särskilda boenden gällande deras arbete med tillämpningen av munhälsobedömningar och deras uppfattning om hur munvård utförs. Metod: Studien genomfördes med kvalitativ deskriptiv design. Data samlades in hjälp av intervjuer med sjuksköterskor (n= 6). Intervjuerna analyserades med hjälp av innehållsanalys och fyra olika teman identifierades: Sjuksköterskors uppfattning om munvård, sjuksköterskors uppfattning om munhälsobedömning, sjuksköterskors uppfattning om munvår och munhälsobedömning i samband med palliativ vård samt sjuksköterskor uppfattning om samarbete med folktandvården. Resultat: Resultatet visade sjuksköterskorna uppfattade att munhälsobedömningar sällan utförs av sjuksköterskorna. Dock ansåg de att munhälsobedömning och munvård utförs regelbundet av såväl sjuksköterskor samt omvårdnadspersonal när vårdtagarna befinner sig i livets slutskede. De eftersöker instruktioner och utbildning av munhälsobedömning enligt ROAG innan detta införs i verksamheten. Munhälsobedömning har utförts av folktandvården en gång om året och de har även kommit till boendena om det finns problem med någon vårdtagares munhälsa. Folktandvården är ansvarig för att skriva vårdtagarnas munvårdskort som är ett stöd för vårdpersonalen vid utförande av daglig munvård. Resultatet har även visat att daglig munvård utförs av undersköterskor och vårdbiträden. Slutsats: Resultatet visar att munhälsobedömning utförs bristfälligt av sjuksköterskor i den kommunala äldreomsorgen. Vidare anser de tillfrågade sjuksköterskorna att utbildning i munhälsobedömningsinstrumentet ROAG är nödvändig innan införandet.

Construction of identity and meaning is becoming increasingly important in both media studies and religion scholarship. (Lövheim, 2004) Meaning construction outside traditional religion has become more interesting for religious studies and what individuals in the audience do with all messages circulated through media in everyday life has attended increasing interest within media studies (Stout and Buddenbaum, 2001). Motion pictures, soap operas and advertising are all examples of media contents which generate ideas among its audience which to a various degree are used as resources within the construction of identity (Jansson, 2001). The investigation of what modern humankind’s world views look like and what components they are composed of, in this context seems to be an important topic of investigation (Holm and Björkqvist, 1996). The ways in which the development of media has effected the daily lives of individuals is interest as is the nature of the self and the ways in which the process of self-formation is affected by the profusion of mediated materials (Thompson, 1995). Film and religion are my interest within this larger frame. The topic is not exactly new but the combination of film and religion has during the last ten years resulted in a rapidly growing number of books by scholars interested in this field (Lyden, 2003). One growing focus is on the role that films can and do play within the emerging and developing valuesystem of people in the West today (Marsh, 2004). The British theologian Clive Marsh’s point of departure is very similar to my own. Viewers bring to a film life-experience, immediate concerns and worldviews and the exploration of this interplay between movies and the interpreting process of meaning making is the very focus in this paper. Theoretically, the semeiological model of Alf Linderman is combined with cultural cognitive approaches used by a number of Scandinavian media scholars developing perspectives in audience theory (Linderman, 1996, Höijer and Werner, 1998). 13 individuals, their favourite movie and what it means to them in their life My aim is to examine how individuals comprehend film and what the meaning process look like. In this paper I present the outcome of 13 interviews with young people about their favourite film. I suggest how it is possible to interpret how they interrelate film comprehension with their personal beliefs and their culturally constructed worldview from a sociocognitive point of view. Examples of films chosen range from Disneys Lion King (1994), sciencefiction and fantasy successes like The Matrix (1999) and Lord of the Rings (2001) or the next best movie ever according to www.IMdb.com The Shawshank Redemption (1994) as well as the Swedish blockbuster Så som i himmelen (2004), aka “As in Heaven”.

Etik kring bilder i annonser har diskuterats mycket, speciellt modell-, ochproduktbilder har kritiserats. Det tycks dock saknas forskning om acceptanskring efterbehandling av landskapsfotografier som ofta används vidmarknadsföring av turistmål. En webbenkätundersökning genomfördes medbildexempel för att undersöka vilken nivå av efterbehandling som ansågsverklighetstrogen, tilltalande och accepterbar i sådana annonser. Slutsatsenblev att fotografier där exponeringen korrigerats för att skapa en tydligare bildvar det mest accepterade. Skillnader i åsikter mellan åldrar, kön, de som haroch inte har tidigare erfarenhet av fotografi och retuschering diskuterades ochdet visade sig att kvinnor och de utan tidigare erfarenhet var lite mer kritiskatill efterbehandling. Det framkom att en del betraktare kan accepteraytterligare efterbehandling om den genomförs för att sälja en specifik känslaoch så länge inte betraktaren kan känna sig vilseledd.
