Doing time in the sociology of education

Abstract

This article is both an editorial introduction for this special issue and a distinctive contribution in its own right. The article seeks to extend a dynamic and multiple conception of time to the sociology of education to think beyond the clock time associated with modernity and industrialisation. This need is illustrated through an account and critique of E.P. Thompson’s canonical account of clock time. The article argues that this construction of clock time implicitly frames most work in the sociology of education. The concept of ‘timespace’ offers a way to go beyond both clock time and the current ‘spatial turn’ in the sociology of education that prioritises space over time. It is shown how computerisation also ushers in a new temporality, which works simultaneously with clock time and perhaps presages the move from a disciplinary to control society. The article accepts that there are multiple and dynamic temporalities and correlatively supports a working together of historical and sociological imaginations towards a sociology of education that acknowledges and works with multiple temporalities, empirically, methodologically, theoretically and in research writing.     

Latino families becoming-literate in Australia: Deleuze,literacy and the politics of immigration

This article examines qualitative data from a two family case study in New South Wales. Both families are from South America and have recently moved to Australia. This study demonstrates that an understanding of the ways that the families are becoming literate in Australia necessitates moving beyond linguistic analyses of the changes that are occurring. The changes that are addressed constitute a politics of immigration, whereby the internal hopes and desires of the family make up an affective plane that transforms language learning. Such writing exemplifies the use of Deleuzian theory in the analysis of the literacy learning of the families, and shows how this rests on notions of the will to power, affect and the multiple nature of the self. The paper will use Masny's (2006) multiple literacies theory (MLT) to reconcile the politics of becoming involved with the immigration of the families and variant modes of expression.

大逻辑观视野——逻辑教学中的教与学

以逻辑的应用性作为问题探讨的切入,以逻辑教学为角度,提出宽泛的逻辑观,认为:逻辑是一个广泛的兼具人文性和科学性的大学科,它的类型是多元的,应是科学性与人文性、工具理性与价值合理性、形式性与非形式性、技术性和交流性的和谐统一。     

基于MUSIC算法的MIMO雷达的角度估计

多输入多输出(Multiple-Input Multiple-Output:MIMO)雷达利用多天线发射互相正交的信号,可以实现灵活的发射分集设计,具有高分辨率的空间谱估计性能。为降低计算的复杂度,提升信噪比高时信号的性能,文章基于MUSIC算法对双基站雷达信号的到达角与发射角作相应估计,结合优化方法和误差准则,对不同参数条件下的该算法作了仿真分析和综合比较。结果证明了该算法的有效性。     

储油罐的变位识别与罐容表标定之建模与分析

通过建立数学模型明确了储油罐的变位对罐容表的影响,较好的处理和分析了罐容表的重新标定问题。首先,对于椭圆型储油罐模型,求出罐体无变位时的理论模型,进行修正,得到了较为准确的修正模型。横向变位β的理论模型。利用实测数据,最小二乘法和变步长收缩方法,求得了相应的角度α=2.1°,β=4.4°,得到了真正的实际模型。最后给出了一个实时观测、处理、修正油罐发生变位时油量标定的系统方法。     

Multiple perpetrator rape among girls evaluated at a hospital-based Child Advocacy Center: Seven years of reviewed cases

The aim of this study was to describe contextual events, abuse experiences, and disclosure processes of adolescents who presented to a hospital-based Child Advocacy Center for medical evaluation and evidentiary collection as indicated after experiencing multiple perpetrator rape during a single event (n = 32) and to compare these findings to a group of single perpetrator sexual assaults (n = 534). This study used a retrospective mixed-methods design with in-depth, forensic interviews and complete physical examinations of gang-raped adolescents. Patients ranged from 12 to 17 years (M = 14 years). Girls who experienced multiple perpetrator rape during a single event were more likely to have run away, to have drunk alcohol in the past month, and to have participated in binge drinking in the past 2 weeks. Acute presentation of these victims were rare but 30% had hymenal transections and 38% had sexually transmitted infections (STIs). Forensic interviews revealed alcohol was a common weapon used by offenders, and its use resulted in victims experiencing difficulty in remembering and reporting details for police investigation or physical and mental health care. Most victims were raped at parties they attended with people they thought they could trust, and they felt let down by witnesses who could have helped but did not intervene. Although relatively rare, multiple perpetrator rape during a single event is a type of severe sexual assault experience and has significant risks for deleterious health outcomes. These victims require health care by trained providers to diagnose physical findings, treat STIs, screen for trauma, and support victims.
