Standing by … standing off – troublesome compassion in the relationships of school boys     

Tuija Huuki  Vappu Sunnari 《Gender and education》2015,27(5):555-574

This paper draws on the story of ‘Mikael’, a schoolboy from northern Finland, to examine how his affective ties of compassion and his pursuit of dominant forms of masculinity evolve in his journey from middle childhood to young adulthood. In his earlier years, Mikael's speech regarding his relationships with peers and family members indicates a non-hierarchical sympathetic orientation, enabling sensitivity to diverse vulnerabilities. Over time, his speech reflects more and more the ideals of dominating masculinity and hierarchical relationality, and it is marked by ‘inner-circle’ compassion that excludes people considered vulnerable and/or ‘Other’. The authors argue that the challenge of balancing compassionate concern, masculinity and social position generates heavy costs, imposing on young men not only the heavy burden of fulfilling the requirements of culturally esteemed masculinity, but also a partial loss of being in touch with one's inner faculties of emotions and imagination.  相似文献   

Learner subjects in study abroad: discourse of immersion,hierarchy of experience and their subversion through situated learning     

Neriko Musha Doerr 《Discourse: Studies in the Cultural Politics of Education》2015,36(3):369-382

This article investigates different kinds of learner subjects that study-abroad programs produce. It is based on discourse analysis and ethnographic fieldwork in May–September 2011, involving three students from a US college studying abroad short term in Europe. The discourse of immersion in study abroad valorizes a learning-by-doing, individual, reflective learner subject who learns alone by gaining everyday experience outside the classroom and by reflecting on it. Some students subverted this discourse and became group and classroom-based learner subjects; nonetheless, they all became reflective learner subjects. This article proposes critical analysis of the discourse and links that reflectivity to critical pedagogy.  相似文献   

Child maltreatment among boy and girl probationers: Does type of maltreatment make a difference in offending behavior and psychosocial problems?     

《Child abuse & neglect》2015

This study examined differences in offending behavior and psychosocial problems between juvenile offenders who have been sexually abused (n = 231), physically abused (n = 1,568), neglected (n = 1,555), exposed to multiple forms of maltreatment (n = 1,767), and non-victims (n = 8,492). In addition, the moderating effect of gender in the association between type of maltreatment and offending behavior/psychosocial problems was examined. Results showed that violent offenses were more common in victims of physical abuse and victims of multiple forms of abuse than in non-victims, both in boys and girls. In boys, sexual offenses were far more common in victims of sexual abuse than in victims of other or multiple forms of maltreatment or in non-victims. In girls, no group differences were found in sexual offending behavior. For both boys and girls, externalizing problems were relatively common in victims of physical abuse and neglect whereas internalizing problems were relatively common in victims of sexual abuse. In victims of multiple forms of maltreatment, both internalizing and externalizing problems were relatively common. Implications for clinical practice are discussed.  相似文献   

Researching elite education: affectively inferred belongings,desires and exclusions     

Claire Maxwell  Peter Aggleton 《International journal of qualitative studies in education》2015,28(9):1065-1080

This paper reflects on key moments occurring during the course of a three-year study of elite girls’ education, with a focus on the power relations that emerged between researchers and elites within the context in which the study was conducted. Central to our analysis is a focus on the affective dimensions of interaction between the researcher and study participants. Our experience gaining access to elite schools in the study illustrates how productive relationships may be fostered by a demonstrated alignment of interests; the desire for intellectual dialogue; and factors linked to the dynamics of the local education market. In our interviews with elite young women, we found that experiences of affinity, foreignness or awe within the interview process triggered different systems of affect. These moments are significant in shaping understandings of the social projects pursued by elite subjects.  相似文献

高校信息技术能力与办学绩效关系的实证研究     

曹郑玉  张守华 《现代远程教育研究》2015,(1):90-97

大量信息技术(IT)投资和应用所引发的"生产率悖论"问题的出现,使人们逐渐认识到IT本身并不一定能给组织带来更好的绩效。资源观理论认为,IT资源与IT能力是两个不同的概念。提高IT能力,才是发挥信息技术战略价值的关键所在。从能力视角对IT能力进行定义,可以将其分为技术性IT能力和管理性IT能力。技术性IT能力包括硬件兼容能力、软件模块化能力、网络连接能力和IT人员技术能力四个子维度;管理性IT能力包括管理能力、关系协调能力和战略匹配能力三个子维度。以工信部所属7所高校为样本,利用结构方程模型和多元回归分析方法,对高校IT能力与办学绩效关系的理论模型进行实证研究。结果显示,高校IT能力由技术性IT能力和管理性IT能力构成,管理性IT能力较技术性IT能力更显著、正向地直接影响高校的办学绩效;同时,管理性IT能力对技术性IT能力也产生了正向影响。  相似文献   

Concreteness fading in learning secondary school physics concepts     

《Learning and Instruction》2022

Concreteness fading has been proposed as a general instructional approach to support learning of abstract mathematics and science concepts. Accordingly, organizing external knowledge representations in a three-step concrete-to-idealized sequence should be more beneficial than the reverse, concreteness introduction, sequence. So far, evidence for the benefits of concreteness fading come mainly from studies investigating learning of basic mathematics concepts. Studies on learning natural science concepts are scarce and have not implemented the full three-step-sequence. In an experimental classroom study (N = 70), we compared concreteness fading and concreteness introduction in high school science education about electromagnetic induction using a detailed assessment. Furthermore, we explored whether these sequences differentially affect the use of the different representations during instruction. Both sequences were equally effective and there were no differences in using the representations. We discuss why our results question the proposed advantages of concreteness fading and highlight conceptual differences and learning goals across domains.  相似文献

Natural surface design for sliding mode control with multiple discontinuous inputs     

Pedro Acosta 《Journal of The Franklin Institute》2014

It is well known that sliding mode control is based on the definition of an invariant manifold, where the system dynamics are forced to in a finite time. Such a manifold is somewhat arbitrarily defined, as long as the system dynamics are stable on it. Computational and control effort may vary depending on selected manifold. Obviously, if a system has naturally acceptable stable dynamics around a desired equilibrium point, no control is needed unless uncertainties or disturbances are present. It would be desirable that if such a system had uncertainties or disturbances, the control effort be designed only to overcome the effect of such factors. For a system with first order dynamics and affine control input, designing a sliding mode control overcoming only such uncertainties or disturbances is a trivial task. When a higher order dynamics system is involved, unit control may be used, where the input control signals are not discontinuous, but when only discontinuous control inputs are available, a design approach is not readily available. In this paper, taking advantage of the natural stable dynamics of a system, a sliding mode control approach is introduced for designing multiple discontinuous control inputs, where the control effort overcomes only uncertainties, disturbances or unstable dynamics. Two illustrative examples are given in order to show the feasibility of the method.  相似文献
