Abstract This paper focuses on the concept of the flâneur, deriving largely from the works of Baudelaire and Walter Benjamin, and attempts to reveal its contemporary relevance for sociological practice. The flâneur is treated as an instructive metaphor for the sociologist's relationship with modernity and urban life, and therefore as providing insight into the social, historical and theoretical contexts for the analysis of the world today. More than this, the idea of the flâneur is treated as highly instructive of research strategies confronting urban life, namely ethnography. The paper seeks to expose a critical space between ‘realist’ and ‘textual’ ethnographies and provide a locus for the discussion of associated methodological problems. A burgeoning literature and tradition of work in this area is examined which will also be of interest to the sociological theorist. 相似文献

Preschool Children's Anticipation of Recipients' Emotions Affects Their Resource Allocation 下载免费PDF全文
The present study investigated the impact of preschoolers' anticipation of recipients' emotions on their resource allocation decisions. Three‐ to six‐year‐old children participated in one of three different scenarios before performing a resource allocation task. In the Other condition, children were led to think about another person's emotions when being shared with or not being shared with. In the Self condition, children were led to think about their own emotion when being shared with or not being shared with. In an epistemic control condition, children were asked to think about another person's knowledge state. The results showed that children were able to attribute different emotions to the respective recipient when being shared with or not being shared with. Children in the Other condition and the Self condition were more likely to allocate resources to the other when decisions were not associated with costs. Moreover, correlational analyses demonstrated that the more negatively children rated the emotion of the recipient when not being shared with the more they were to allocate resources to the recipient. This indicates that children's inclination to allocate resources to another person can be promoted by their awareness of a recipient's negative emotions when not being shared with. 相似文献

This paper explores the salience of the “crisis” in boys’ education as it is articulated in Australian print media. We will consider the ways in which this crisis is expressed through a gendered language which simultaneously represents boys as “forgotten” by teaching practices thought to be prioritising girls’ learning, and as an equity (disadvantaged) grouping who require specialised teaching methods different from those currently offered within the Australian school system. Further, we will examine the extent to which feminist-inspired reforms in education are either implicitly or explicitly referenced as an explanation for boys’ apparently poor education attainment, and relatedly consider the work of “experts” supporting claims of a pro-feminine bias that adversely affects boys’ learning outcomes, particularly those experts offering neurological or psychological/cognitive findings which assert a biological basis for gender difference. In this context, we argue that rather than advancing gender equity in schools, popular public discourse, as presented in Australian print media, reinforces and perpetuates notions of gender difference and masculine entitlement. 相似文献

A honeynet is a portion of routed but otherwise unused address space that is instrumented for network traffic monitoring.
It is an invaluable tool for understanding unwanted Internet traffic and malicious attacks. We formalize the problem of defending
honeynets from systematic mapping (a serious threat to their viability) as a simple two-person game. The objective of the
Attacker is to identify a honeynet with a minimum number of probes. The objective of the Defender is to maintain a honeynet for as long as possible before moving it to a new location within a larger address space. Using
this game theoretic framework, we describe and prove optimal or near-optimal strategies for both the Attacker and the Defender.
This is the first mathematically rigorous study of this increasingly important problem on honeynet defense. Our theoretical
ideas provide the first formalism of the honeynet monitoring problem, illustrate the viability of network address shuffling,
and inform the design of next generation honeynet defense systems. 相似文献

In this paper, we study the impact of child care subsidy receipt on low-income children’s weight outcomes in the fall and
spring of kindergarten using data from the Early Childhood Longitudinal Study, Kindergarten Cohort. Our results suggest that
subsidy receipt is associated with increases in BMI and a greater likelihood of being overweight and obese. Using quantile
regression methods, we find substantial variation in subsidy effects across the BMI distribution. Specifically, child care
subsidies have no effect on BMI at the lower end of the distribution, inconsistent effects in the middle of the distribution,
and large effects at the top of the distribution. Our results point to the use of non-parental child care, particularly center-based
services, as the key mechanism through which subsidies influence children’s weight outcomes. 相似文献

This exploratory study sought to determine if a popular school-based drug prevention program might be effective in schools that are making adequate yearly progress (AYP). Thirty-four schools with grades 6 through 8 in 11 states were randomly assigned either to receive Project ALERT (n = 17) or to a control group (n = 17); of these, 10 intervention and nine control schools failed to make AYP. Students completed three self-report surveys. For lifetime cigarette use and 30-day alcohol use, Project ALERT was more effective in schools that made AYP. However, in these schools, Project ALERT negatively affected students' lifetime marijuana use. This study provided some preliminary evidence that prevention programming may not work as well in poorer performing schools; however, further exploration is needed. 相似文献
