Disciplinary exclusion: wicked problems in wicked settings     

Fiona Hallett  Graham Hallett 《Journal of Research in Special Educational Needs》2021,21(Z1):8-16

This paper uses Rittel and Webber’s categorisation of wicked problems in order to interrupt discourses around school behaviour. Each of the 10 characteristics suggested by Rittel and Webber are examined using the English education system as a vehicle by which to consider and interrogate their complexity. This endeavour is crucial as although the characteristics of wicked problems naturally overlap, the cannot, and should not, be conflated if we wish to understand how different facets of a wicked problem shed light, and create shadows, that impact on all members of a school community. That school communities can be wicked settings adds nuance to the complexity of the problems that we face when educating students whose behaviours challenge the norms of their educational environment.  相似文献   

Association between psychosocial stressors with emotional and behavioral problems among children of low-income addicted families living in Brazil     

《Child abuse & neglect》2019

BackgroundChildren exposed to substance use in their families are vulnerable to multiple risk factors in their development and at increased risk for emotional and behavioral problems. The aims of the study were as follows 1) estimate the prevalence of emotional and behavioral problems among children aged 6–11 years old, living with addicted family members in a low-income urban community of São Paulo, Southeastern Brazil; 2) evaluate the children’s exposure to family psychosocial stressors and substance use; and 3) investigate the factors related to the increased risk of emotional and behavioral problems and substance use.MethodsA cross-sectional study was conducted among 101 children aged 6–11 years old (M = 9.16 years, SD = 1.61). The instruments used were a sociodemographic questionnaire, the Child Behavior Checklist (CBCL) and the Psychosocial Stress Factors (PSF).ResultsHigh prevalence of problems was found for this sample: the CBCL showed 26.7% of clinical scores for Internalizing Problems, 40.6% for Externalizing Problems, and 40.6% for Total Problems. Exposure to family psychosocial stressors was also high, including severe disease (33%), physical aggression (28.9%), death (27.8%), psychiatric hospitalization (16.7%), suicide attempts (15.5%), and suicide (9.3%). Exposure to these family stressors was associated with an increase of two to four times in the prevalence of internalizing and externalizing problems.ConclusionsChildren exposed to substance abusers have more mental health problems than general population, even when compared to peers living in similar low-income areas. This is a group that should be target of a selective preventive intervention.  相似文献   

Reciprocal Versus Nonreciprocal Assessment of Knee Flexors and Extensors in Concentric Actions Using the CON-TREX Multijoint Isokinetic Dynamometer: A Reliability Study     

Alex Bliss  Jeanne Dekerle 《Measurement in physical education and exercise science》2019,23(2):118-123

Knee flexor and extensor muscular assessment via isokinetic dynamometry is common practice and established in the research literature. However, reporting assessment methodology regarding reciprocal and nonreciprocal movements is often vague or absent. Such methodological issues are crucial for accurate assessments. Therefore, knee extensor and flexor peak moment using either reciprocal movement or nonreciprocal modalities was assessed. Fifteen participants performed three blocks of five concentric muscle actions at three angular velocities [1: nonreciprocal (maximal active flexion followed by passive extension); B2: reciprocal (maximal active extension followed by maximal active flexion); B3 nonreciprocal (maximal active extension followed by passive flexion)]. ANOVA revealed statistically significant within-subject modality effects for peak knee extensor moment and flexor velocity and modality differences (p < .05). Reciprocal and nonreciprocal assessments give significantly different results, with nonreciprocal giving higher peak moments. Reporting which modality is used is crucial to allow for greater clarity for the reader and practitioner.  相似文献   

Exploring mechanisms of rapid automatized naming to arithmetic skills in Chinese primary schoolers     

Yiji Wang  Xiaolin Ye  Ciping Deng 《Psychology in the schools》2020,57(4):556-571

Rapid automatized naming (RAN) is associated with children's arithmetic performance, which is multifactorial by nature and consists of arithmetic fluency, arithmetic procedure, and word problems. Yet, it is unclear whether RAN can predict all key aspects of arithmetic skills independently and what cognitive mechanisms may explain this relation. Using a sample of Chinese primary school students (N = 170), results showed that while RAN was associated with all key aspects of arithmetic skills, the relations of RAN–arithmetic procedure and RAN–word problems may be dependent on that of RAN–arithmetic fluency. Supporting the processing speed hypothesis, results further suggested that processing speed may underlie the relation between RAN and arithmetic performance. Findings made unique contribution to understanding the effect of RAN on arithmetic performance and cognitive mechanisms that may underpin this association in the context of Chinese culture.  相似文献   

海绵城市、城市公园、城市建筑与绿色城市     

曹婷  连之伟  周武忠 《中国名城》2021,(4):8-14

“绿色”作为现代城市主题,将“城市种进大自然”成为由城市建设不当导致生态问题的核心解决策略。依据设计实践和相关案例分析,可提出:(1)海绵城市的核心治理理念和目前建筑能耗相关概念结合,以“削峰填谷”解决环境、城市内涝问题。(2)城市公园设计必须从生态的丰富内涵出发,尊重城市地格,同时注意整个城市的公园联络性,形成城市空间内的自然轴线.。(3)垂直绿化不仅是单一的绿色外观建筑设计形式,还需要和建筑功能空间、理念结合,让自然这个元素由外向内渗透到建筑内部、人居环境、人们健康饮食以及健康生活方式甚至是思想观念,从建筑外观或者城市形象来增添城市与自然的相关性。  相似文献   

A new conceptualization of mega sports event legacy delivery: Wicked problems and critical realist solution     

《Sport Management Review》2020,23(2):171-182

The authors present a new conceptualization of mega sports event legacy delivery, which accounts for the problematic nature of legacy by viewing it as a wicked problem. Research on mega sports event legacy has focused on establishing typologies of legacy, investigating outcomes, and consequences, with limited attention to legacy delivery. The conceptualization of legacy delivery has largely relied on a positive, utopian legacy rhetoric. In contrast, the authors advance the understanding of legacy by proposing a conceptual approach of the legacy delivery process, to enable empirical studies in different contexts to be conducted. Specifically, the authors examine the wicked problem of mega sports event legacy delivery from a Critical Realist perspective, which serves to give meaning and order to this complex process. This conceptualization reveals that legacy delivery is inclusive of deep social structures which underpin different stakeholders’ interpretations and interactions, which produce or limit legacy delivery. The role of social, generative structures as causal mechanisms has not been considered as a way to understand legacy delivery previously. Implications for teaching, research, and practice are discussed to demonstrate the value of this new approach. Importantly, this conceptualization focuses on processes rather than outcomes and encourages the identification of unexpected or unanticipated components of legacy delivery beyond the formal policies and plans designed to create or leverage legacy.  相似文献
