This essay explores representations of poverty in art. In so doing, the visual arts are offered as a supplement to traditional textual studies of poverty. The depiction of poor children in particular is rare before the modern period, and reasons for this are explored. Significant literary and artistic treatments of children in poverty, which begin to appear in the 19th century, are considered in the context of philosophical, political, and economic developments of the time. The New York painter of street children J. G. Brown represents Victorian era painters of poor children in that he distanced himself and his images from reality. More involved in the lives of the poor was the early 20th-century German printmaker Ka¨the Kollwitz, who steered away from the impetus to abstraction of that period in favor of an emotionally charged, politicized, activist approach which focused on the topic of children in misery. Finally, the use of photographs to document poor children is briefly summarized to set the stage for a consideration of the work of Wendy Ewald. This artist's novel approach of giving poor children the means to depict themselves and their own world breaks down the barrier between artist and subject and unifies them in a common purpose.  相似文献

This paper presents a summary and excerpts taken from the psychoanalytic treatment, spanning over 16 years, of a highly disturbed and provocative male patient. Prior to referral, the man had been unsuccessfully treated psychopharmacologically for a depressive illness with severe somatic and affective symptoms and behavioral disturbances. A highlight of the case is the emergence of a therapeutic impasse that developed around the patient's attempt to connect intensely with the analyst; the patient attempted to repair his own damaged phallic narcissism by demanding that the analyst participate in a ritualized sexual enactment, which threatened the destruction of the treatment process. The resolution of the impasse was accomplished through the analyst's reaffirming the frame and recovering his own disrupted composure and ref lectiveness, while maintaining a compassionate and caring attitude toward the patient.  相似文献

In this paper, we have studied some implications between tail-ordering (also known as dispersive ordering) and failure rate ordering (also called TP2 ordering) of two probability distribution functions. Based on independent random samples from these distributions, a class of distribution-free tests has been proposed for testing the null hypothesis that the two life distributions are identical against the alternative that one failure rate is uniformly smaller than the other. The tests have good efficiencies as compared to their competitors.  相似文献

Abstract

This study investigated the gender-specific, self-reported sexual behaviors and attitudes of never-married college students attending a southeastern university in 1973 and 1988. Data were collected by means of a mailed questionnaire that remained essentially unchanged for both years. The authors found that both men and women reported an increase in heterosexual relationships that included sexual intercourse and a decrease in nonsexual relationships with the other gender. The majority of the students perceived themselves as adequately informed about sexuality and satisfied with their relationships, although the proportion of men who reported being satisfied with their relationships declined over the 15 years. The students indicated that sexuality education should focus primarily on information about AIDS and on preparation for marriage.  相似文献

A prevalence of heavy-tailed, peaked and skewed uncertainty phenomena have been cited in literature dealing with economic, physics, and engineering data. This fact has invigorated the search for continuous distributions of this nature. In this paper we shall generalize the two-sided framework presented in Kotz and van Dorp (Beyond beta: other continuous families of distributions with bounded support and applications. World Scientific Press, Singapore, 2004) for the construction of families of distributions with bounded support via a mixture technique utilizing two generating densities instead of one. The family of Elevated Two-Sided Power (ETSP) distributions is studied as an instance of this generalized framework. Through a moment ratio diagram comparison, we demonstrate that the ETSP family allows for a remarkable flexibility when modeling heavy-tailed and peaked, but skewed, uncertainty phenomena. We shall demonstrate its applicability via an illustrative example utilizing 2008 US income data.  相似文献

Recent innovations in Web-based technology tools have made planning instruction with technology in mind far more doable than in years past. To aid teachers in planning with technology, tools are organized into five broad categories: communication, collaboration, presentation, organization and critical-thinking. The purpose and potential of each group of tools is explored and utilized in the development of a technology-rich unit plan on medieval China.  相似文献

A study to investigate the human immunodeficiency virus (HIV) status on the course of neurological impairment, conducted by the HIV Center at Columbia University, followed a cohort of HIV positive and negative gay men for 5 years and assessed the presence or absence of neurological impairment every 6 months. Almost half of the subjects dropped out before the end of the study for reasons that might have been related to the missing neurological data. We propose likelihood-based methods for analysing such binary longitudinal data under informative and non-informative drop-out. A transition model is assumed for the binary response, and several models for the drop-out processes are considered which are functions of the response variable (neurological impairment). The likelihood ratio test is used to compare models with informative and non-informative drop-out mechanisms. Using simulations, we investigate the percentage bias and mean-squared error (MSE) of the parameter estimates in the transition model under various assumptions for the drop-out. We find evidence for informative drop-out in the study, and we illustrate that the bias and MSE for the parameters of the transition model are not directly related to the observed drop-out or missing data rates. The effect of HIV status on the neurological impairment is found to be statistically significant under each of the models considered for the drop-out, although the regression coefficient may be biased in certain cases. The presence and relative magnitude of the bias depend on factors such as the probability of drop-out conditional on the presence of neurological impairment and the prevalence of neurological impairment in the population under study.  相似文献

Regulations under the 1990 Amendments to the Clean Air Act impose significant requirements on firms handling hazardous chemicals. The nature of the regulations would suggest that small firms, because of limited resources and other structural limitations, would experience more difficulty complying with the regulations than large firms. To understand the difficulties imposed by the regulations on small firms, we interviewed ten small firms in Delaware and New Jersey, states with existing hazardous regulations similar to those being considered by the U.S. Environmental Protection Agency, and evaluated their responses to state regulations. The impacts of the environmental regulations on the firms and on the risk levels of their businesses are discussed. Propositions for research into small firms compliance are developed. Possible means for reducing the regulatory burden on small firms while enhancing regulatory effectiveness are suggested.  相似文献
