The Key Role of the School Principal’s Leadership in the Schooling of Newly Arrived Immigrant Pupils in Sweden : Experiences from an Interactive Action Research Project

When newly immigrated children and young people begin school in Sweden, certain challengesarise. These may result from weak Swedish-language skills and different schooling backgrounds,as well as organizational and pedagogical limitations in the schools. This generates demands onschool leaders to lead and develop the organization and teachers competences to meet these pupils’needs. This situation was behind the initiation of the project “New Immigrants and Learning—Competence Development for Teachers and School Principals.” The project ran in schools infour Swedish municipalities, its aim was to develop leadership, organizational and pedagogicalskills that would facilitate the schooling and integration of newly arrived pupils. This article aimsto describe and discuss a Participant Action Research (PAR) based on a think tank and researchcircles, drawing special attention to the role of the school leaders. It will also examine whether theresearch circles and the project overall served to develop educational and intercultural leadership,organizational conditions, collegial learning, pedagogical methods and competence in terms ofschooling for this pupil group.

Formen aus Stahl, Bauteile aus Titan und Stahl

Die Arcam Technologie setzt erstmals weltweit mit der ‚CAD to Metal®’ Methode einen Elektronenstrahl ein. Mit dieser Methode können homogene Stahlkomponenten und Formen in kürzester Zeit aus einem Metallpulver geschmolzen werden. Die in zunehmendem Maße geforderte Herstellung von Prototypen im Zielwerkstoff, wird mit dem EBM Verfahren erstmals für Stahl- und Titanwerkstoffe ermöglicht. Die Arcam-Methode setzt CAD-Datenmodelle direkt in homogene Metallmodelle um. Mit der Einbringung von konturnahen Kühlkanälen ist es nun auch machbar, Werkzeuge in hochlegierten Stählen im Rapid Prototyping Verfahren herzustellen. So erstellte Werkzeuge können die Zykluszeiten im Spritzguss- und Druckgussprozess um 30% verringern. Die Festigkeiten liegen ohne jegliche Nachbehandlung bei ca. 50 Rockwell. Jede beliebige Formgebung ist sofort in Stahl und neuerdings auch in Titan zu erstellen. Von besonderer Bedeutung ist, dass konturnahe Kühlungen in beliebiger Komplexität integriert werden. Die Arcam Technologie stellt die schnellste Produktionsmöglichkeit von Funktionsprototypen dar, welche in Festigkeit und Temperaturstabilität die gleichen Parameter wie herkömmliche gefertigte Bauteile aufweist. Es stehen Werkzeugstahl (DIN 1.2344), legierte Stähle und Titan (Ti6A14V) zur Verfügung. Die EBM Technologie setzt einen Elektronenstrahl zum Aufschmelzen der Metallpulver ein. Stahl wird z.B. mit einer Temperatur von 1700 °C schichtweise aufgetragen. Ein Verschleiß, wie man ihn von Anlagen mit Lasertechnologie kennt, tritt nicht auf. Neuinvestition in Abständen von 3000 – 4000 Betriebsstunden sind bei dieser Technologie für neue Laser nicht notwendig. Die Arcam-Technologie ist in 24 Ländern patentrechtlich geschützt. Arcam ist ein schwedisches Unternehmen, mit Sitz in Mölndal in der Nähe von Göteborg.

Decision-usefulness of ideal cost- and ideal value accounting for valuation and stewardship

This paper contrasts the decision-usefulness of prototype accounting regimes based on perfect accounting for value, i.e. ideal value accounting (IVA), and perfect matching of cost, i.e. ideal cost accounting (ICA). The regimes are analyzed in the context of a firm with overlapping capacity investments where projects earn excess returns and residual income is utilized as performance indicator. Provided that IVA and ICA systematically differ based on the criterion of unconditional conservatism, we assess their respective decision-usefulness for different valuation- and stewardship-scenarios. Assuming that addressees solely observe current accounting data of the firm, ICA provides information which is useful for valuation and stewardship without reservation whereas IVA entails problems under specific assumptions.

64Cu- and 68Ga-labelled [Nle(14),Lys(40)(Ahx-NODAGA)NH2]-exendin-4 for pancreatic beta cell imaging in rats.

PURPOSE Glucagon-like peptide-1 receptor (GLP-1R) is a molecular target for imaging of pancreatic beta cells. We compared the ability of [Nle(14),Lys(40)(Ahx-NODAGA-(64)Cu)NH2]-exendin-4 ([(64)Cu]NODAGA-exendin-4) and [Nle(14),Lys(40)(Ahx-NODAGA-(68)Ga)NH2]-exendin-4 ([(68)Ga]NODAGA-exendin-4) to detect native pancreatic islets in rodents. PROCEDURES The stability, lipophilicity and affinity of the radiotracers to the GLP-1R were determined in vitro. The biodistribution of the tracers was assessed using autoradiography, ex vivo biodistribution and PET imaging. Estimates for human radiation dosimetry were calculated. RESULTS We found GLP-1R-specific labelling of pancreatic islets. However, the pancreas could not be visualised in PET images. The highest uptake of the tracers was observed in the kidneys. Effective dose estimates for [(64)Cu]NODAGA-exendin-4 and [(68)Ga]NODAGA-exendin-4 were 0.144 and 0.012 mSv/MBq, respectively. CONCLUSION [(64)Cu]NODAGA-exendin-4 might be more effective for labelling islets than [(68)Ga]NODAGA-exendin-4. This is probably due to the lower specific radioactivity of [(68)Ga]NODAGA-exendin-4 compared to [(64)Cu]NODAGA-exendin-4. The radiation dose in the kidneys may limit the use of [(64)Cu]NODAGA-exendin-4 as a clinical tracer.

Pedagogiken i tiden : Om framväxten av nya undervisningsformer under tidigt 2000-tal – exemplet Kunskapsskolan

The study concerns the new educational activities that emerge within the deregulated school system at the beginning of the 21st century. Which ideas guide the work? How is the activity formed? What does one hope to achieve? The aim of the thesis is to explore these educational practices in one of the larges independent schools in Sweden – Kunskapsskolan. The study was based upon a sociocultural perspective on learning and on twenty situated interviews with seven principals. Tools central for the activity in Kunskapsskolan were used as basis for the interviews. A qualitative analysis has been used; one of the methods for analysis applied is phenomenography. The study shows how the school, with the help of centrally developed tools, organised the teaching and the environments for learning that were implemented in all schools of the company. Individually organised teaching is the foundation for all teaching, where the students are expected to be self-regulated and self-correcting and use the tools provided for their learning. With regards to the students’ learning, the teachers’ role is mainly related to individual tutorial conversations. Thereby the tools intended to create freedom and control for the students, also create problems and obstacles. Students who do not learn to use the tools have difficulties in managing their studies. The new tools also affect the teachers’ work. In comparison with other schools, the teachers are expected to submit to the educational model and a centrally controlled planning. The teaching is centrally planned in subject specific stages or subject integrated courses. Teachers can influence the central planning by working collaboratively in teacher teams but not individually. The main commission of the teachers is to follow the educational model decided by the company. In comparison with the traditional school, both teachers and students are given new roles. When learning is individually organised for the students, the teachers are expected to develop their knowledge collectively. According to the results, both students and teachers have different approaches to the system – they can submit to the system or approach it in a more independent and reflective way.

La lectura como actividad de ocio en escolares asturianos de 6º de primaria

Este trabajo analiza los resultados de una investigación sobre hábitos lectores del alumnado asturiano de 6º de Educación Primaria en su tiempo libre. El estudio utiliza una muestra de 324 escolares de centros públicos urbanos, con edades comprendidas entre los 11 y 12 años, para analizar datos relativos a la actitud hacia la lectura, la importancia de ésta entre las actividades de ocio y la frecuencia lectora.Más de la mitad de los escolares manifiesta una actitud bastante favorable hacia la lectura, y ésta es una de sus actividades de ocio habituales, aunque dedican más tiempo a ver televisión, practicar deportes, usar el ordenador y escuchar música. La mayoría son lectores frecuentes, aunque los no lectores y lectores ocasionales ascienden hasta un 12,96%. Los escolares encuestados leen principalmente libros, seguidos de revistas y cómics, mientras que poco más de un tercio dice leer periódicos frecuentemente.Esta investigación revela también algunas variaciones en actitud hacia la lectura y frecuencia lectora según el centro educativo de procedencia que se pueden relacionar con variables de tipo socio-económico. Además, se observan diferencias entre niños y niñas, pues éstas superan a sus compañeros varones en interés y frecuencia lectora, además de manifestar también divergencias en las preferencias de materiales de lectura.

Suosittelulla lisää uusia asiakkaita

Asiakashankintaa tehdään monin tavoin. Suosittelua asiakashankinnan keinona on tutkittu tieteellisissä tutkimuksissa melko vähän. Tämän tutkimuksen tavoitteena on selvittää asiakashankinnan ja suosittelun nykytilaa kohdeorganisaatiossa, kehittää suosittelua osaksi myyntiprosessia ja tunnistaa aineettomia resursseja, joita voidaan hyödyntää asiakashankinnan ja suosittelun tehostamisessa tietojohtamisen avulla. Tutkimus on kvalitatiivinen tapaustutkimus ja sen tavoitteisiin pyritään vastaamaan survey kyselyn sekä puolistrukturoitujen haastatteluiden (14kpl) avulla. Tutkimuksen kohdeorganisaationa on Suomessa toimiva pankki- ja rahoitusalan yhtiö. Suosittelun käyttöä asiakashankinnan keinoa tutkittiin kohdeorganisaation yrityksen pankkineuvojien ja heidän esimiesten näkökulmasta. Empiirinen tutkimus antaa vastauksen asetettuihin tutkimuskysymyksiin sekä vastaa tutkimuksen tavoitteisiin. Tutkimuksessa löydettiin suositteluun ja yleisesti asiakashankintaan liittyviä aineettomia resursseja, joita hyödyntämällä ja johtamalla suosittelun nykyistä käyttöä voidaan kehittää tehokkaammaksi.
