Connecting does not necessarily mean learning: Course handbooks as mediating tools in school-university partnerships
No full textThis is the author's accepted manuscript (titled "Course handbooks as mediating tools in learning to teach"). The final published article is available from the link below. Copyright @ 2011 American Association of Colleges for Teacher Education.Partnerships between schools and universities in England use course handbooks to guide student teacher learning during long field experiences. Using data from a yearlong ethnographic study of a postgraduate certificate of education programme in one English university, the function of course handbooks in mediating learning in two high school subject departments (history and modern foreign languages) is analyzed. Informed by Cultural Historical Activity Theory, the analysis focuses on the handbooks as mediating tools in the school-based teacher education activity systems. Qualitative differences in the mediating functions of the handbooks-in-use are examined and this leads to a consideration of the potential of such tools for teacher learning in school–university partnerships. Following Zeichner’s call for rethinking the relationships between schools and universities, the article argues that strong structural connections between different institutional sites do not necessarily enhance student teacher learning
Reenergising professional creativity from a CHAT perspective: Seeing knowledge and history in practice
No full textThis is the author's accepted manuscript. The final published article is available from the link below. Copyright @ 2011 Regents of the University of California.This article offers a critical examination of aspects of a practice- and theory-developing intervention in the teacher education setting in England designed as a variation of Developmental Work Research. A positive case is argued for the distinctiveness of such cultural-historical activity theory [CHAT-] informed interventions and some points of contrast are drawn with the British tradition of educational action research. In describing the practice-developing intervention, the twin focus on seeing knowledge and history in human activity systems is advanced as two dimensions of CHAT's distinctive approach, with the goal of stimulating and studying the emergence of professional creativity. Creativity under this interpretation is defined as the perception and analysis of opportunities for learning within the social situation of development and the production of new conceptual tools and approaches to the social organisation of work. Professional creativity is advanced as a much needed capacity among teachers in industrial workplaces influenced by the techniques of New Public Management. Common ground between CHAT and action research approaches is seen in their optimistic and modernist commitments to progress, and CHAT-framed interventions, like action research approaches, are presented as part of an evolving intellectual project
The use of evidence in language and literacy teaching
No full textLiteracy education deserves evidence-based decisions. Low literacy costs the British economy between £1.73bn and £2.05bn per year (KPMG 2006) and the social and emotional costs are equally high. Yet we know that children who struggle with literacy can make fast progress when the instructional content and pedagogy closely match their needs. This chapter describes some of the paradigms and problems associated with the use of evidence in language and literacy education with examples from specific interventions and programmes. It raises issues about how literacy teachers are professionalized to attend to evidence, both the evidence in front of them and the research evidence 'out there'. It argues that to support teachers in using evidence effectively, we need to frame the research evidence about effective content, pedagogy and learning in ways that recognize the power and limitations of different evidence paradigms. To ensure that all children make fast progress, we need to appreciate how teachers develop broad and diagnostic understandings of literacy and literacy learning and of how policy and curriculum frameworks impact on the classroom decisions they make
Movement and stagnation - the impact of the environment on perceptions of self, body and breathlessness in COPD
No full textMeasurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ
No full textThe ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is
B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd),
where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5.
The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be
ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%.
Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations
Ellis-van Creveld Syndrome
No full textEllis-van Creveld syndrome also known as chondroectodermal dysplasia is a rare genetic disorder of the skeletal dysplasia type, first described by Richard WS Ellis and Simon van Creveld in 1940. The syndrome manifests with several skeletal anomalies, oral mucosal and dental anomalies, congenital cardiac defects, nail dysplasia and polydactyly of one or both limbs. It is caused by mutation of EVC1 and EVC2 genes located in a head-to-head configuration on chromosome 4p16, which has been identified as the causative. The EVC phenotype is variable and affects multiple organs. The presence of oral mucosal and dental alterations, like the presence of numerous frenulum, oligodontia, bellshaped anterior teeth, hypoplastic erupted teeth with high-caries index, will confirm the diagnosis of Ellis-van Creveld syndrome and hence its importance to dentists
Establishment of the contemporary Slovenian author
No full textKoncept avtorja se je skozi čas spreminjal. V antiki je avtor veljal za avtoriteto, vzor in genija, v (post)strukturalizmu, ko je osrednje mesto zavzel tekst, so razglašali avtorjevo smrt, v današnjem času hiperprodukcije literature pa je ponovno obujen, njegova vloga pa korenito predrugačena: avtor s tem, ko sodeluje v promociji, književnemu delu omogoča preživetje. Avtor, ki se ne želi tržiti, na književnem trgu posledično obstane le s težavoče želi, da njegovo delo ni spregledano, mora biti viden in se zavestno uveljavljati. Prav proces uveljavljanja raziskujem tudi v svoji magistrski nalogi. Podrobneje me zanima, katere entitete omogočajo avtorjevo uveljavljanje in do kakšne mere se kot posameznik lahko zoperstavlja tržni logiki. Ker odločilno vlogo v tem procesu igrajo mediji in založbe, sem opravila intervjuje s petimi slovenskimi medijskimi uredništvi (in raziskala, na kak način izbirajo avtorje, o katerih poročajo, kako skrbijo za uravnovešenost, na kak način prestavljajo avtorje ipd.) ter s šestimi založbami (zanimalo me je, kako pristopajo k promociji, kakšni avtorji so zanje zanimivi, kako sodelujejo z mediji ipd.). Kot pomemben faktor v procesu uveljavljanja oboji omenjajo literarne nagrade, predvsem nagrado kresnik, ki jo podeljuje časnik Delo – vlogi slednje se posvečam v zadnjem poglavju. V sklepu izpostavljam dobre prakse, ki v slovenskem prostoru prispevajo k uveljavljanju še neuveljavljenih avtorjev, in podajam predloge izboljšav, do katerih bi lahko prišlo v medijih in založništvu.The concept of the author has changed over time. In antiquity, the author was considered an authority, a role model and a geniusin (post-)structuralism, when the text took centre stage, the death of the author was proclaimedin today\u27s age of the hyperproduction of literature, the author has been revived, and his/her role radically reshaped: the author, by taking part in the promotion, enables the literary work to survive. The author who does not want to market himself/herself will consequently find it difficult to stay on the literary marketif he/she wants his/her work not to be overlooked, he/she must be visible and consciously assert himself/herself. In my master’s thesis, this process of assertion has been explored. In more detail, I am interested in which entities enable the author to assert himself/herself and to what extent can he/she as an individual challenge the logic of the market. Since the media and publishing houses play a decisive role in this process, I interviewed five Slovenian media editorial offices (to find out how they choose the authors they cover, how they ensure balance, how they shift authors, etc.) and six publishing houses (to find out how they approach promotion, which authors are interesting to them, how they cooperate with the media, etc.). Both mention literary prizes as an important factor in the process of promotion, especially the kresnik prize awarded by the Delo newspaper – the role of the latter is discussed in the last chapter. In the conclusion, good practices that contribute to the promotion of non-established authors in Slovenia are highlighted and suggestions for improvements that could be made in the media and publishing are listed
Ellis-van Creveld Syndrome in Grey Alpine Cattle: Morphologic, Immunophenotypic, and Molecular Characterization
No full textEllis-van Creveld (EvC) syndrome is a human autosomal recessive disorder caused by a mutation in either the EVC or EVC2 gene, and presents with short limbs, polydactyly, and ectodermal and heart defects. The aim of this study was to understand the pathologic basis by which deletions in the EVC2 gene lead to chondrodysplastic dwarfism and to describe the morphologic, immunohistochemical, and molecular hallmarks of EvC syndrome in cattle. Five Grey Alpine calves, with a known mutation in the EVC2 gene, were autopsied. Immunohistochemistry was performed on bone using antibodies to collagen II, collagen X, sonic hedgehog, fibroblast growth factor 2, and Ki67. Reverse transcription polymerase chain reaction was performed to analyze EVC1 and EVC2 gene expression. Autopsy revealed long bones that were severely reduced in length, as well as genital and heart defects. Collagen II was detected in control calves in the resting, proliferative, and hypertrophic zones and in the primary and secondary spongiosa, with a loss of labeling in the resting zone of 2 dwarfs. Collagen X was expressed in hypertrophic zone in the controls but was absent in the EvC cases. In affected calves and controls, sonic hedgehog labeled hypertrophic chondrocytes and primary and secondary spongiosa similarly. FGF2 was expressed in chondrocytes of all growth plate zones in the control calves but was lost in most EvC cases. The Ki67 index was lower in cases compared with controls. EVC and EVC2 transcripts were detected. Our data suggest that EvC syndrome of Grey Alpine cattle is a disorder of chondrocyte differentiation, with accelerated differentiation and premature hypertrophy of chondrocytes, and could be a spontaneous model for the equivalent human disease
