E.E.肯明斯是美国著名的先锋诗人。他的诗歌形式变异,语言分裂,在世界诗坛独树一帜。多年来,一些学者主要从他的语言和形式上探讨他的诗歌,认为他过分追求诗歌的形式,难免在主题上缺少应有的深刻度。但笔者认为,与其说肯明斯是用一种特立独行的方式与世界对话,倒不如说他标新立异的诗句正是他灵魂的投影,内心的独白。本文将依据文学批评的相关理论,探讨肯明斯诗歌的主题。  相似文献

Equivariant functions can be useful for constructing of maximal invariant statistic. In this article, we discuss construction of maximal invariants based on a given weakly equivariant function under some additional conditions. The theory easily extends to the case of two or more weakly equivariant functions. Also, we derive a maximal invariant statistic when the group contains a sharply transitive and a characteristic subgroup. Finally, we consider the independence of invariant and weakly equivariant functions under some special conditions.  相似文献

Using data from 7272 adolescent US girls, we explore how girls’ race/ethnic group status affects their bodyweight, perceptions of overweight, and weight control practices. We hypothesize that a girl’s race/ethnic status influences her basic identity which in turn prompts her to adopt or reject a “drive for thinness.” After controlling for family and peer support, school engagement, family SES, maturation, and family structure, we find that girls’ race/ethnic status influences their susceptibility to the thinness ideals of mainstream culture. African American girls weigh more than Asian, Hispanic, or White girls, but at any given weight they perceive themselves as overweight and attempt to control their weight less. Asian American and White girls invest most in thinness dynamics. Some evidence also suggests girls from lower SES families are less driven to be thin. Our results affirm the utility of viewing material bodies as “situations” that are experienced and interpreted in accord with identity group relations and dynamics.  相似文献

ABSTRACT

In this article, we study the recursive kernel estimator of the conditional quantile of a scalar response variable Y given a random variable (rv) X taking values in a semi-metric space. Two estimators are considered. While the first one is given by inverting the double-kernel estimate of the conditional distribution function, the second estimator is obtained by using the robust approach. We establish the almost complete consistency of these estimates when the observations are sampled from a functional ergodic process. Finally, a simulation study is carried out to illustrate the finite sample performance of these estimators.  相似文献

This paper focuses on an important line of inquiry in contemporary criminal justice social work research: the collateral consequences of incarceration in the Chinese context. It gives an insight into the impact of incarceration on families from an insider's perspective. An analysis of interviews with 10 partners and 10 children yielded three major themes concerning the impact of imprisonment: the problems associated with the imprisonment of a family member, the coping strategies used and views on the importance of maintaining family ties. It is hoped that this study will give practical guidance regarding what should be done, and how, to reduce the negative consequences brought about by the absence (temporary or permanent) of the imprisoned on their families, including both their partners and vulnerable children.  相似文献

Abstract

Making use of a formulation by Rosalie Kane of the ingredients necessary to “a good life” for residents of homes for the aged and other long term care facilities, the role of the social worker in insuring the presence of these ingredients is discussed. Included is an analysis of the responsibilities and tasks of the social worker which must be carried and fulfilled in order that social workers make appropriate contributions to “the good life.”  相似文献

自伊斯兰教先知穆罕默德注释《古兰经》起,《古兰经》注释便逐渐发展成为伊斯兰文化体系中举足轻重的传统学科——主释学(‘ilma1-tafsir)。注释学历经两大时期形成并完善:口耳相传时期——枞先知穆罕默德时期到再传弟子时期;文字记载时期——始于阿拔斯王朝早期,结束期不得而知。注释学的发展以及涌现出的大量学术成果,彰显出历代穆斯林阐释《古兰经》微言大义的学术动态,反映了伊斯兰文化学术的纵深发展。  相似文献

ABSTRACT

Traditionally, prospective resource parents must attend all preservice training in person. Although live sessions are necessary for screening applicants, instructional portions of training could be enhanced by Web-based sessions. This pilot study compares the effectiveness of online and classroom versions of one session from a widely used preservice training program. Ninety-two individuals enrolled in the program in two states were randomly assigned to a treatment group that viewed an online version of the class on child abuse and neglect or to a comparison group that took the same class in person. Written questionnaires were completed before and after the class. Significant group differences on knowledge of child maltreatment and empathy toward birth parents plus high user satisfaction were hypothesized. Analysis of covariance results showed the online training was more effective than the live training at increasing knowledge. Multivariate analysis of covariance findings on empathy were not significant but trended toward greater empathy for the online group. Feedback indicated high satisfaction with the online course. The finding that online instruction is more effective than live instruction has positive implications for practice, because Web-based training offers advantages like standardizing instruction, cutting agency and trainee costs, and providing greater flexibility.  相似文献
