Teachers in early childhood policy

This paper examines teacher accountability and authority in early childhood policy. It reports on data from a study that investigated the influences affecting early childhood teacher decision-making at the preschool level in Victoria, Australia. Using a question raised by Ball ‘Where are the teachers in all this [policy]?’ provided a starting point for the critical discourse analysis into how forms of control, teacher authority, obligation and constraint within policies potentially influenced teachers’ curriculum decisions. The study found that despite no government-mandated curriculum framework at the time, teachers were held accountable for their curricular practice. Yet as professionals, early childhood teachers were denied public acknowledgement of their expertise as they were almost invisible in policy. In the four policies analysed, proprietors of early childhood settings and preschool agencies held authority over curriculum. Subsequently, teachers’ authority as professionals with curricular knowledge was diminished.     

Morphological and biochemical responses of Oryza sativa L. (cultivar MR219) to ion beam irradiation

Objective

Heavy ion beam, which has emerged as a new mutagen in the mutation breeding of crops and ornamental plants, is expected to result in the induction of novel mutations. This study investigates the morphological and biochemical responses of Oryza sativa toward different doses of carbon ion beam irradiation.

Methods

In this study, the dry seeds of O. sativa were irradiated at 0, 20, 40, 60, 80, 100, and 120 Gy, followed by in-vitro germination under controlled conditions. Morphological and biochemical studies were conducted to investigate the morphological and physiological responses of O. sativa towards ion beam irradiation.

Results

The study demonstrated that low doses (10 Gy) of ion beam have a stimulating effect on the height, root length, and fresh weight of the plantlets but not on the number of leaves. Meanwhile, doses higher than 10 Gy caused reductions in all the morphological parameters studied as compared to the control samples. The highest total soluble protein content [(2.11±0.47) mg/g FW] was observed in plantlets irradiated at 20 Gy. All irradiated plantlets were found to have 0.85% to 58.32% higher specific activity of peroxidase as compared to the control samples. The present study also revealed that low doses of ion beam (10 and 20 Gy) had negligible effect on the total chlorophyll content of O. sativa plantlets while 40 Gy had a stimulating effect on the chlorophyll content. Plantlets irradiated between 40 to 120 Gy were shown to be 0.38% to 9.98% higher in total soluble nitrogen content which, however, was not significantly different from the control samples.

Conclusions

Carbon ion beam irradiation administered at low to moderate doses of 10 to 40 Gy may induce O. sativa mutants with superior characteristics.     

Focusing on the Thinking,Not the Tools: Incorporating Critical Thinking Into an Information Literacy Module for an Introduction to Business Course

Two librarians at the University of Louisville explain how a university-wide Quality Enhancement Plan focused on critical thinking led to positive changes in information literacy instruction at their institution. A revised information literacy module for an introductory business course serves as an example of a new instructional approach that emphasizes critical thinking about information, rather than library tools such as catalogs and databases.     

Translation as problematic discourse in organizations

Translation as an organizational activity is critical to the effective functioning of many institutions and is becoming ever more commonplace as our society grows increasingly multilingual and culturally diverse. This study examines translation in terms of its influence on organizational members' sensemaking and consequent social and task functions of the institution. An integrated theory of translation provides a foundation for identifying three major categories of problematics involving translation in workplaces: inaccuracies, losses of common sociocultural contexts, and changes to power relationships. Data from a hotel business meeting in which an executive's discourse in English were simultaneously translated into Spanish is analyzed to illustrate the problematics and to derive guidelines for organizations with multilingual workforces.     

Metaphor use and perceived managerial effectiveness

This study examines the metaphorical language of three managers in a Northwest city government. Four communication specialists used an interpretative method to identify, categorize, and rate perceptions of metaphors in three 30‐minute transcribed interviews. The results establish a set of metaphor categories, support a theory of culturally‐shared metaphors, demonstrate managers' differences in metaphor use, and suggest an association between managers metaphor use and subordinate ratings of effectiveness.     

Collaboration Between the University of Michigan Taubman Health Sciences Library and the University of Michigan Medical School Office of Research

Librarians have traditionally facilitated research development resulting in grants through performing biomedical literature searches for researchers. The librarians at the Taubman Health Sciences Library of the University of Michigan have taken additional steps forward by instituting a proactive approach to assisting investigators. To accomplish this, the librarians have taken part in a collaborative effort with the University of Michigan Medical School Office of Research. Through this partnership, both units have created and adopted various techniques intended to facilitate the submission of grants, thus allowing researchers more time to conduct their primary activities.     

Children with dyslexia are slow writers because they pause more often and not because they are slow at handwriting execution

It is commonly assumed that children with dyslexia are slower at handwriting than other children. However, evidence of slow handwriting in children with dyslexia is very mixed. Thirty-one children with dyslexia, aged 9 years, were compared to both age-matched children and younger spelling-ability matched children. Participants completed an alphabet-writing task and a composition task on the surface of a digital writing tablet. Children with dyslexia wrote the same amount of letters per minute in the alphabet task but wrote fewer words per minute when composing their texts than children of the same age. Crucially, no differences were found between children with dyslexia and their same age peers for speed of handwriting execution, measured by the tablet, when writing the alphabet or composing their texts. However, children with dyslexia were found to pause within their compositions as often as the spelling ability matched group. Thus handwriting execution is not impaired in children with dyslexia. The slow writing that is typical of children with dyslexia is due to pausing more often when composing and is related to spelling ability. This may reflect processing problems in response to high cognitive load through having to contend with spelling and composing concurrently.     

Looking to the future: producing transdisciplinary professionals for leadership in early childhood settings

This paper reports on an Australian initiative Developing and Sustaining Pedagogical Leadership in Early Childhood Education and Care Professionals, where academics and professionals shared knowledge, experience and research about transdisciplinary practice. The project aimed to develop an understanding of the strategies and skills early childhood professionals and practitioners required to strengthen pedagogical leadership when working in multi-agency organisations. The conceptual framework underpinning the design, analysis and evaluation of the project was bricolage. Bricolage enabled the researchers, professionals and practitioners and other organisational members to consider the principles of multiplicity, complexity, relationality and criticality. The use of bricolage created an opportunity for a more comprehensive level of analysis to occur. A model of professional development emerged from the analysis of the data and was subsequently used to develop an open source learning website.
