To support organizational efforts in leadership development, performance improvement professionals must be prepared to use a variety of development methods along with the right mix of strategies that enhance learning transfer. Regardless of the development methods used, leadership development programs that incorporate strategies to enhance learning transfer in the areas of leadership support, evaluation, and organizational issues are likely to be more successful than development programs that ignore transfer barriers in these critical areas. 相似文献

Gerald Caplan (1917–2008), world-renowned child and community psychiatrist, was the originator of the modern practice of mental health consultation. In addition to consultation, Caplan developed and refined many conceptual models and methods for practice for use in community mental health, psychology, and education. This tribute article focuses on his career and contributions to the field of consultation and offers insights into his approach to mental health consultation. 相似文献

This study explored preschool teachers' beliefs about the appropriateness of early literacy and mathematics education. In all, 60 teachers of 4-year-olds, half working with low-socioeconomic status (SES) children at publicly funded preschools and the other half with middle-SES children at private preschools, were randomly assigned to read either the mathematics or the literacy versions of written vignettes describing issues related to teaching these subjects. Teachers were interviewed individually concerning the vignettes. Analyses showed that teachers of middle-SES children tended to support literacy and mathematics education that respects individual children and their preferences and to oppose classroom use of computers; overall they emphasized nonacademic areas. Teachers of low-SES children tended to focus on literacy and mathematics to prepare children for kindergarten and to support computer use; they showed concern about their students' underdeveloped readiness to learn, particularly literacy. Analyses comparing subject matter showed that for literacy, teachers preferred to gear a curriculum toward children's interests and to allow children to follow their interests in a literacy-rich classroom to promote social competence and positive dispositions toward literacy. For mathematics, teachers preferred to embed mathematics into everyday routines to promote the learning of key knowledge and skills throughout the day. These findings have significant implications for professional development. 相似文献

This study focused on combining both the group- and individual-level analyses in studying a collaborative activity in technology-enhanced interactions in a higher education setting. The aim was to make visible, with empirical examples, the quality of the students' web-based discussions and trace the route for shared understanding. By quantifying various communicative functions, the analysis provided general knowledge on the quality and purpose of the discussion in the group and highlighted the different functional positions each student had within the group. However, only a detailed interpretative analysis of the relationships between specific thematic contents, communicative functions, and the collaborative features of the discussion, in the temporal frame, made it possible to trace and gain a deeper understanding of the true acts of collaboration. It also highlighted the individual participants' different participatory and discursive positions in the different phases of the task. Over the study, it became evident that any attempts to define a collaborative activity from either the group's or individual's perspective would only result in a partial interpretation of the collaborative enterprise. 相似文献

ABSTRACTBackground: Cycling has gained more attention as an important lifelong physical activity. Learning to cycle independently without assistance is a milestone for most children that requires time and practice to master. Cycling was recently added to the motor development model and so a valid and reliable measure of cycling ability is required to allow accurate assessment of the skill. Cycling has many health benefits along with being a commonly reported physical activity globally and therefore is an important skill to promote in early childhood and throughout life. To date, there are no measurement tools examining the developmental process to independent cycling in the early childhood years. The current study aimed to develop and assess the inter-rater and test-retest reliability of the ‘KIM Cycling Scale’.Methods: Development of the scale occurred in four phases: (1) development of criteria and stages, which used observation of children when learning to cycle and expert panels to develop the initial developmental stages, (2) review of instructions and criteria and pilot inter-rater and test-retest reliability, to ensure that the scale could be used as a standalone scale without requiring further instructions (3) cycling intervention, which allowed assessment of the developmental nature of children along the scale as they learn to cycle independently and to assess typical and alternate routes to independent cycling and (4) inter-rater and test-retest reliability.Results: Ninety children took part in phase 1, thirty-six children took part in phase 2, seventy-four children took part in phase 3 and one hundred and forty-nine children took part in phase 4. All three hundred and forty-nine children were between 2 and 6 years. The developed scale included eight stages in total. The scale was found to have excellent inter-rater reliability (ICC?=?0.97, 95% CI?=?0.96–0.98) and good to excellent test-retest reliability [(ICC?=?0.91, 95% CI?=?0.87–0.94) & (ICC?=?0.90, 95% CI?=?0.85–0.93)]. Typical routes to independent cycling along the scale were examined and reported as being step-wise on all occasions except one where a two stage jump was as common as the step-wise route. Alternate routes were also reported.Conclusion: The current study developed a reliable measurement tool for assessing children between 2 and 6 years of age on the developmental process to independent cycling. Having a cycling scale will allow teachers and practitioners to assess competence in cycling and moreover, track changes in skill development. Furthermore, parents could also use the scale to better understand and better asses their child’s progression when learning to cycle. 相似文献

ABSTRACT Many museums are housed in historic buildings, sometimes the building itself is part of the museum collection. Creating a stable environment by providing a nearly constant temperature and relative humidity at correct levels decreases the risk of object degradation. Maintaining this steady indoor environment, however, increases energy consumption and risks to the historic building. Museum display cases offer a solution to the mitigation of risks to which valuable objects may be subjected by providing an extra layer of protection to indoor climate fluctuations. The Anne Frank House is a historic house museum located in Amsterdam. The museum has undergone several renovations in the last years to deal with an increase in the number of visitors to over 1.2 million a year. The original diaries and other documents of Anne Frank are permanently on display in the Anne Frank House. With the recent refurbishment the possibility arose to design a new state-of-the-art display case. This study presents the results of the experimental research related to the design, performed in-situ. The temperature and relative humidity in the new exhibition space and inside the new display cases were monitored to gain insight into the hygrothermal behavior of these controlled environments. A complementary numerical study was performed to investigate effects of dynamic climate control of the exhibition gallery and climate conditions in the display case under various circumstances. Four main conclusions are presented in this paper. The investigated display case design is able to provide a stable relative humidity environment by means of silica gel, while using an active box-in-box climate control system to create stable temperature conditions. The inner case temperature depends on the temperature supplied by the display case air handling unit. Protocols must be in place in case of malfunction or failure of the climate control system of the display case. The air handling unit of the case needs to be shut off to create a passive environment for the objects on display until necessary actions are taken. Exhibition gallery set points can be less stringent when susceptible museum objects are on display in the display case. The environments are separated and provide an opportunity for energy saving set point strategies. The last conclusion drawn is that the numerical study provides valuable insight into imposing dynamic control of set points for temperature and relative humidity in the exhibition gallery and the effect on the display case environment. 相似文献

ABSTRACTResearch grant funding influences the organisation of academic work and academic careers. We problematise general approaches to gender bias in research grant funding and argue that it fails to include the wider structures of inequality and the unequal gendered power relations in academia. Approaching the subject with gender budgeting we challenge assumed gender-neutral practices. The objective is to illuminate how the gendered funding system and (the previous and subsequent) gendered structures of academia are maintained. The whole grants scheme is assessed, drawing on statistical data collected on the whole population of a medium-size, comprehensive research and educational institution in Iceland, and two types of competitive grants. The data is measured against the pool of applicants and comparisons within and between fields and ranks are made. By including the structures of inequality and the gendered power relations, the results show how the funding system is biased not only in favour of men, but towards the male-dominated and culturally masculine positions and fields. This approach illustrates the need to address the whole academic system in order to challenge the norms that maintain and reproduce gender inequalities. 相似文献
