Affordances for Risky Play in Preschool: The Importance of Features in the Play Environment     

Ellen Beate Hansen Sandseter 《Early Childhood Education Journal》2009,36(5):439-446

The purpose of this article is to qualitatively explore the affordances for risky play in two different preschool outdoor environments, an ordinary preschool playground and a nature playground, based on Gibson (The ecological approach to visual perception, 1979) theory of affordances and Heft’s and Kytte?’s (Heft in Children’s Environ Qual 5(3) 29–37, 1988; Kytt? in J Environ Psychol 22:109–123, 2002, Kytt? in J Environ Psychol 24:179–198, 2004) extended work on this theory. Observations of risky play in two Norwegian preschools, one ordinary preschool (where play took place on an ordinary playground) and one nature and outdoor preschool (where play took place in a nature area) were conducted. In addition, the children were interviewed about their actualized affordances of risky play, their mobility license, and the constraints on risky play. The results show that both play environments afford an extensive amount of risky play among the children, and that the degree of mobility license tolerated by the staff is an important factor for the children to actualize these affordances. Differences in the qualities and features in the two play environments were found to have an impact on the degree of riskiness in the play situations. As such, the nature playground afforded a higher degree of risk in children’s risky play.  相似文献   

Future pest status of an insect pest in museums,Attagenus smirnovi: Distribution and food consumption in relation to climate change

The brown carpet beetle Attagenus smirnovi, Zhantiev 1973 (Coleoptera: Dermestidae) is an important pest of objects of organic origin in museums of cultural and natural history in Europe. Future climate changes are expected to lead to increasing temperatures, which will affect the pest status of this species. In the present study a laboratory investigation was conducted to elucidate the effect of temperature and humidity on the amounts of organic material consumed by larvae of A. smirnovi. In the case of new and old skin, consumption was approximately twice as high at 28 °C compared to 20 °C. Wool was consumed in the greatest amounts: 169 mg of wool was consumed in three months by 30 A. smirnovi larvae. The expected future climate changes in Scandinavia are assumed to lead to higher temperatures in museums and stores where climate is not regulated. Updated data on the present distribution of A. smirnovi in Europe show that it is widespread and common, also in regions with a climate that does not support its survival out of doors. Thus, dispersal of this pest probably only rarely occurs by flight, but usually with human activity. Due to the widespread distribution of A. smirnovi, it is likely that damages in museums and collections in Scandinavia due to this pest will increase as climate changes come into effect.  相似文献   

Scaring the Monster Away: What Children Know About Managing Fears of Real and Imaginary Creatures     

Liat Sayfan  Kristin Hansen Lagattuta 《Child development》2009,80(6):1756-1774

Children around 4, 5, and 7 years old (N = 48) listened to scenarios depicting a child alone or accompanied by another person (mother, father, friend) who encounters an entity that looks like a real or an imaginary fear‐inducing creature. Participants predicted and explained each protagonist’s fear intensity and suggested coping strategies. Results showed age‐related increases in judgments that different people will experience different intensities of fear in the same situation. With age, children also demonstrated increasing knowledge that people’s minds can both induce and reduce fear, especially in situations involving imaginary creatures. Suggestions of reality affirmation strategies (e.g., reminding oneself of what is real vs. not real) significantly increased with age, whereas positive pretense strategies (e.g., imagining it is a friendly ghost) significantly decreased.  相似文献   

Residing in silence and wonder: career counselling from the perspective of ‘being’     

Finn Thorbjørn Hansen  Norman Amundson 《International Journal for Educational and Vocational Guidance》2009,9(1):31-43

We are approaching career counselling from the perspective of “Being”, which we recognize to be a daunting task. Nevertheless we find it extremely important that the counsellor become aware of and try to think, talk and act from his or her embeddedness in being, and by that help the client to do the same. This process involves an ontological and spiritual approach, and builds upon the Socratic ability to wonder, the meditative way of “undoing” and the artful act of creation.  相似文献   

The importance of the advisor’s relational and professional competence and formal power in meetings with farmers     

Bjørn Gunnar Hansen  Egil Petter Stræte  Gunn-Turid Kvam 《The Journal of Agricultural Education and Extension》2018,24(4):361-375

Purpose: The aim of the paper is to explore how advisors’ relational and professional competence influences inter-subjectivity and farmers’ perceptions of farm visits in a setting where advisors have formal power.Methodology: Advisors from the dairy company Tine, which is owned by farmers in collaboration, visit farmers at least once a year. The aim of the visit is to assist farmers in managing the farm and to control the production conditions in the cowshed. In a case study, we attended 10 such mandatory advisor visits and interviewed both farmers and advisors.Findings: Together with advisor style, our findings show that the power relation leaves room for advisors to define their roles widely, ranging from inspector to coach. Advisors have different perceptions of what their jobs are and when they have done a good job. These differences determine the degree of inter-subjectivity and how satisfied farmers are with visits. Furthermore, advisors’ relational and professional competencies are crucial for achieving high inter-subjectivity and satisfied farmers.Theoretical implications: This paper contributes to the theory by identifying factors that influence farmers’ perceptions of advisor visits, as well as by showing the importance of the advisor’s relational and professional competence in a setting where they have formal power.Practical implications: Partly as an outcome of this study, Tine has started a process to separate the control function from farm visits. Tine has also decided to let farmers choose advisors themselves. Originality/value: The power relation in our study differs from most consultant–client interactions in the literature.  相似文献   

Adipose tissue lipolytic inhibition enhances the glucoregulatory properties of exercise in type 2 diabetes patients     

Dominique Hansen  Jan-Willem van Dijk  Antoine Zorenc  Lennert Minten  Kevin Smeets 《European Journal of Sport Science》2018,18(9):1245-1254

Aims: Exercise combined with adipose tissue lipolytic inhibition augments intramuscular lipid and glycogen use in type 2 diabetes patients. The present study investigates the impact of adipose tissue lipolytic inhibition during exercise on subsequent postprandial glycemic control in type 2 diabetes patients.

Methods: Fourteen male type 2 diabetes patients (age 65?±?2 years, HbA_1c 6.7?±?0.1% (50?±?2?mmol/mol)) participated in a double-blind placebo-controlled randomized cross-over study in which subjects performed endurance-type exercise after being administered 250?mg of a nicotinic acid analogue (acipimox; ACP) or a placebo (PLA). A control experiment was included in which no exercise was performed (CON).

Results: Sixty minutes of endurance-type exercise (at 45% W_peak) did not significantly lower circulating plasma glucose and insulin excursions in PLA when compared with CON (P?=?.300). Acipimox administration strongly reduced circulating plasma FFA concentrations during exercise (P?i.e. postprandial) in ACP when compared with either CON (P?=?.041 and P?=?.002, respectively) or PLA (P?=?.009 and P?=?.001, respectively).

Conclusions: Collectively, exercise with adipose tissue lipolytic inhibition reduces postprandial blood glucose and insulin excursions and, as such, further improves glycemic control in male type 2 diabetes patients.  相似文献

Using Instrumental Variables to Account for Selection Effects in Research on First-Year Programs     

Gary R. Pike  Michele J. Hansen  Ching-Hui Lin 《Research in higher education》2011,52(2):194-214

The widespread popularity of programs for first-year students is due, in large part, to studies showing that participation in first-year programs is significantly related to students’ academic success. Because students choose to participate in first-year programs, self-selection effects prevent researchers from making causal claims about the outcomes of those programs. The present research examined the effects on first-semester grades of students participating in themed learning communities at a research university in the Midwest. Results indicated that membership in themed learning communities was positively associated with higher grade point averages, even after controlling for entering ability, application date, gender, and first-generation/low-income status. However, when instrumental variables were introduced to account for self-selection, the effects of themed learning communities on grades were not statistically significant. The results have implications for campus leaders and assessment practitioners who are working to develop methods for understanding the effects of programs designed to enhance the undergraduate educational experiences on their campuses.  相似文献   

Geometrical optimization of microstripe arrays for microbead magnetophoresis     

Anders Dahl Henriksen  Noemi Rozlosnik  Mikkel Fougt Hansen 《Biomicrofluidics》2015,9(5)

Manipulation of magnetic beads plays an increasingly important role in molecular diagnostics. Magnetophoresis is a promising technique for selective transportation of magnetic beads in lab-on-a-chip systems. We investigate periodic arrays of exchange-biased permalloy microstripes fabricated using a single lithography step. Magnetic beads can be continuously moved across such arrays by combining the spatially periodic magnetic field from microstripes with a rotating external magnetic field. By measuring and modeling the magnetophoresis properties of thirteen different stripe designs, we study the effect of the stripe geometry on the magnetophoretic transport properties of the magnetic microbeads between the stripes. We show that a symmetric geometry with equal width of and spacing between the microstripes facilitates faster transportation and that the optimal period of the periodic stripe array is approximately three times the height of the bead center over the microstripes.  相似文献
