EFFECTIVE SCHOOL LEADERSHIP PRACTICES IN SCHOOLS WITH POSITIVE CLIMATES IN THE AGE OF HIGH-STAKES TEACHER EVALUATIONS
The purpose of this research project was to understand the leadership practices and characteristics of school leaders within schools identified as having a positive school climate. In this qualitative study, three focus groups of teachers were interviewed and asked a series of questions about their principalsâ professional practices and characteristics. The building principals from these schools were also interviewed individually. These responses were scripted and analyzed using an open-coding model and then compared to recent educational leadership literature. Key findings from this research include professional practices and characteristics of principals in schools with positive climate, as well as recommendations for current and future school leaders and possibilities for future research
Economic stress in childhood and adulthood, and self-rated health: a population based study concerning risk accumulation, critical period and social mobility
Background: Research in recent decades increasingly indicates the importance of conditions in early life for health in adulthood. Only few studies have investigated socioeconomic conditions in both childhood and adulthood in relation to health testing the risk accumulation, critical period, and social mobility hypotheses within the same setting. This study investigates the associations between economic stress in childhood and adulthood, and self-rated health with reference to the accumulation, critical period and social mobility hypotheses in life course epidemiology, taking demographic, social support, trust and lifestyle factors into account. Methods: The public health survey in Skane (southern Sweden) in 2008 is a cross-sectional postal questionnaire study based on a random sample, in which 28,198 persons aged 18-80 years participated (55% participation). Logistic regression models were used to investigate associations between economic stress in childhood and adulthood, and self-rated health. Results: Three life-course socioeconomic models concerning the association between economic stress and self-rated health (SRH) were investigated. The results showed a graded association between the combined effect of childhood and adulthood economic stress and poor SRH in accordance with the accumulation hypothesis. Furthermore, upward social mobility showed a protecting effect and downward mobility increased odds ratios of poor SRH in accordance with the social mobility hypothesis. High/severe economic stress exposures in both stages of life were independently associated with poor SRH in adulthood. Furthermore, stratifying the study population into six age groups showed similar odds ratios of poor SRH regarding economic stress exposure in childhood and adulthood in all age groups among both men and women. Conclusions: The accumulation and social mobility hypotheses were confirmed. The critical period model was confirmed in the sense that both economic stress in childhood and adulthood had independent effects on poor SRH. However, it was not confirmed in the sense that a particular window in time (in childhood or adulthood) had a specifically high impact on self-rated health
Antibodies pÄ Trapholt - en udstilling mere underholdende end oplysende
Museet Trapholt huser netop nu Campana brĂždrenes vĂŠrker i udstillingen Antibodies. Udstillingen er imponerende, og det er gode historier om brĂždrenes udgangspunkt i materialerne vi fĂ„r ved en guidet tur rund blandt de mange voluminĂžse, farverige, sĂŠrlige vĂŠrker. Men det er alt hvad museumsgĂŠsten bliver prĂŠsenteret for; gode, lettere indholdslĂžse historier, og intet dybereliggende rationale bag fremvisningen af disse sĂŠrlige mĂžbler. Dette lĂŠgger op til en mere overordnet diskussion af museumsinstitutionen i vores samfund â hvad bĂžr designmuseets rolle vĂŠre? Det kan ikke kun handle om kulturel underholdning, designmuseet mĂ„ tillige have et formidlingsansvar overfor de besĂžgende og tage deres rolle som oplysende institution alvorlig â og dette uanset hvad der er udgangspunktet for museets fremvisning af designgenstande
A simple way to evaluate self-designed probes for tumor specific Multiplex Ligation-dependent Probe Amplification (MLPA)
<p>Abstract</p> <p>Background</p> <p>The Multiplex Ligation-dependent Probe Amplification (MLPA) is widely used for analysis of copy number variations (CNVs) in single or multiple loci. MLPA is a versatile methodology and important tool in cancer research; it provides precise information on increased or decreased copy number at specific loci as opposed to loss of heterozygosity (LOH) studies based upon microsatellite analysis. Pre-designed MLPA kits and software are commercially available to analyze multiple exons, genes, and genomic regions. However, an increasing demand for new gene specific assays makes it necessary to self-design new MLPA probes for which the available software may not be applicable. During evaluation of new self-designed reference probes, we encountered a number of problems, especially when applying the MLPA methodology to tumor samples.</p> <p>Findings</p> <p>DNA samples from 48 unaffected individuals and 145 breast cancer patients were used to evaluate 11 self-designed MLPA probes and determine the cut-off values for CNV, before applying the MLPA probes to normalize the target probes in a cohort of affected individuals. To test the calculation strategy, three probes were designed to cover regions in Regulator of G-protein Signaling 8 (<it>RGS8</it>), which we previously have identified as being affected by allelic imbalance by LOH analysis across <it>RGS8 </it>in the cohort comprising 145 breast tumors. Agreement between the LOH results and the results obtained by each of the three MLPA probes in <it>RGS8 </it>was found for 64%, 73%, and 91%, of the analyzed samples, respectively.</p> <p>Conclusion</p> <p>Here, we present a straightforward method, based upon the normalization pattern in both unaffected and affected individuals, to evaluate self-designed reference probes and to calculate CNV for the MLPA assay with specific focus on the difficulties when analyzing tumor DNA.</p
«à har fortsatt myredialÊkt! à snakke ikkje sÄnn sÄ di i TromsÞ!» En sprÄkvitenskapelig masteravhandling om sprÄkvariasjon, dialekt og holdninger hos seks ÞksnesvÊringer i TromsÞ by
I denne masteravhandlingen er sprĂ„k pĂ„ flyttefot i fokus. Hva skjer med sprĂ„ket nĂ„r man flytter pĂ„ seg, og hva skjer nĂ„r flyttingen skjer mellom bygd og by? Seks innflyttere i TromsĂž som opprinnelig kommer fra Ăksnes kommune i Nordland ble intervjuet, og gjennom transkripsjon har jeg kartlagt sprĂ„kene deres. Informantene hadde bodd i TromsĂž i alt fra 7 til 18 Ă„r, og gruppen utgjorde tre kvinner og tre menn i alderspennet 27-37 Ă„r. Ved Ă„ se etter noen bestemte leksikalske, morfologiske eller fonologiske variabler (som tradisjonelt sett er ulike mellom ĂžksnesmĂ„l og tromsĂžmĂ„l), ble det telt og registrert variasjon. Det teoretiske rammeverket utgjorde akkommodasjonsteorien, og teorien om sosiale nettverk. Hvorvidt er det snakk om sprĂ„klig tilpasning hos informantene? Eller har det sosiale nettverket rundt dem noe Ă„ si? I tillegg ble de sosiolingvistiske begrepene "status" og "prestisje" anvendt i forsĂžket pĂ„ Ă„ forklare den eventuelle sprĂ„kvariasjonen som ble registrert. Andre sosiale variabler som sprĂ„k og identitet, samt holdninger, alder og kjĂžnn ble trukket inn i oppgaven

FÞlelser i politik: en ny tilgang til at forstÄ politisk adfÊrd
FÞlelser bliver ofte anset for at vÊre problematiske i et demokratisk samfund, hvor rationaliteten efter sigende bÞr rÄde. Men fÞlelser er reelt uomgÊngelige i politik, fordi politik handler om mennesker, og fÞlelser gennemsyrer al menneskelig beslutningstagning. Denne artikel giver en introduktion til forskningen i fÞlelser i politik, der er inde i en hastig udvikling i disse Är. Artiklen behandler, hvad fÞlelser er, og giver et overblik over en rÊkke specifikke fÞlelsers funktioner, eksempelvis vrede, medfÞlelse og frygt, samt deres konsekvenser for politisk adfÊrd. Med afsÊt i seks udbredte misforstÄelser runder artiklen af med at opstille seks principper for, hvordan fÞlelsers betydning for politik kan forstÄs
Four cases on market orientation of value chains in agribusiness and fisheries
This working paper presents results from the project âSupra-company level determinants of degree of market orientation of value chains in agriculture and fisheriesâ, which is carried out in cooperation between MAPP â Centre for Research on Customer Relations in the Food Sector, Aarhus School of Business, Denmark, the Norwegian College of Fisheries Science, University of TromsĂž, Norway, and the Department of Marketing, University of Stirling, Scotland. It has benefited from grants from the Danish Social Science Research Council and from the Norwegian Research Council. The present working paper is the âlongâ version of the empirical work in the first major phase of the project, where we study four examples of food value chains to get insight into their degree of market orientation and possible determinants. The insights gained here have been used in subsequent empirical work that is currently underwayMarket orientation;
