Dirty writing     
On 16 August 2006 we watched Life of Grime: New York on Australia’s Channel 10 television network. The camera followed a group of ‘grime professionals’ cleaning up the streets of New York. They cleaned rats, dogs and other peoples’ dirt. One guy struck us as particularly interesting. His job was cleaning the streets after suicides. His latest assignment was someone who had recently jumped from an apartment block of 17 floors, a woman. He enjoyed scrubbing the railing which caught her flesh as she fell, the blood fresh on the sidewalk. As he hosed down the street with complete detachment from the dirt he was cleaning, the blood just ran, slipping away – life having already slipped away. The debris was fresh and easy to remove. Stale dirt, hardened blood, crusty flesh is harder to brush away and with it better hydraulics are required to sterilize the streets, he told us. Maybe writing is like this. Ignoring the material(ity) of the dirt. Pretending that it didn’t come from real people. Forgetting the damaged lives that produce the dirt. Removing the dirt from view. And our dirt is so encrusted, so hard to sanitize despite our massive cleaning efforts.  相似文献

ABSTRACT

Welfare reform has been successful in helping clients achieve self-sufficiency. However, some individuals experience problems associated with basic needs, physical health, mental health, substance abuse, and intimate partner violence (IPV) that can impede transitioning from welfare to work and/or interfere with parental responsibilities. The Targeted Assessment Program (TAP) was created more than a decade ago to identify and address these problems and help clients move off the welfare rolls in Kentucky. Self-reported interview data were used to examine changes and effect sizes between baseline assessment and 6-month follow-up from a sample (n = 322) of Temporary Assistance for Needy Families-eligible clients participating in Kentucky's TAP. Using McNemar's test for correlated proportions, paired-sample t-tests, and measures of effect size, significant changes with varied effect sizes were found for selected basic needs, as well as physical health, mental health, substance use, and IPV barriers. Findings suggest that social service practitioners could incorporate strengths-based case management and motivational interviewing into their practice. Further research is suggested utilizing longitudinal and controlled studies on evidence-based practice that address pretreatment and assessment strategies involving case management and motivational interviewing.  相似文献

Summary Home areas of hosts are, in effect the gardens in which parasite populations grow. The parasites flourish in response to the kind and amount of host activity modified, of course, by the habitat, and become microcommunities supported by their host and its artifacts. When scatter diagrams of points at which hosts have been observed are divided by median major and minor axes, and when the resulting four quarters, designated A, B, C, D, corresponding to concentration of points in the quarters, the relative concentration usually is: A>B>C>D. The concentration of observed points also is generally greatest nearest the major axis and frequently, but not always, near the median center. Nests of hosts, hence nest-parasites, appear generally to be near the center. For the host examined in detail here, the New Guinea coarse-haired rat, mostLeptotrombidium deliensis appear to have been acquired in the AB sector of the host's home areas but a greater diversity of chiggers is acquired in the CD sector. It is postulated that, ifL. akamushi had been present, it would have occurred in the CD sector where, though the observed concentration of host activity was least, the mixed grassforb and shrub habitat would have been more suitable than in the AB sector.Gahrliepia pingue, C. ewingi, Schoengastia blestowei andS. schueffneri, appear also to be more abundant in the CD sector than in the AB sector. The chiggers themselves have home clusters, or lairs, and adjacent areas of activity (home areas) somewhat resembling those of the hosts. This analysis of sectors of home areas was begun in 1965 under provision of a research grant (AI-03653) by the National Institutes of Health to the Division of Parasitology, University of California at Berkeley. It was completed during 1967.  相似文献

OBJECTIVE AND PARTICIPANTS: The authors evaluated the effects on stress, rumination, forgiveness, and hope of two 8-week, 90-min/wk training programs for college undergraduates in meditation-based stress-management tools. METHODS: After a pretest, the authors randomly allocated college undergraduates to training in mindfulness-based stress reduction (MBSR; n = 15), Easwaran's Eight-Point Program (EPP; n = 14), or wait-list control (n = 15). The authors gathered pretest, posttest, and 8-week follow-up data on self-report outcome measures. RESULTS: The authors observed no post-treatment differences between MBSR and EPP or between posttest and 8-week follow-up (p > .10). Compared with controls, treated participants (n = 29) demonstrated significant benefits for stress (p < .05, Cohen's d = -.45) and forgiveness (p < .05, d = .34) and marginal benefits for rumination (p < .10, d = -.34). CONCLUSIONS: Evidence suggests that meditation-based stress-management practices reduce stress and enhance forgiveness among college undergraduates. Such programs merit further study as potential health-promotion tools for college populations.  相似文献

Though collaboration is often required in community initiatives, little evidence documents relationships between collaboration and program success. The authors contend that clarification of the construct collaboration is necessary for investigating its contribution to the success of community initiatives. After respecifying collaboration, they present a study of a multisite program that involved varying degrees of collaboration in the 16 communities adopting a nurse home visitation program. The authors employ hierarchical linear modeling (HLM) to test the predictive power of individual participant characteristics and examine the increased accuracy of predictions from a second level model of site qualities-specifically, features of the collaborative process associated with different sites. The first-level model predicted approximately 10% of the variance in attrition, or dropout, of program clients. The second-level model accounted for an additional 28% of the variance in attrition. A theory of commitment transfer is offered as a first explanation of this result.  相似文献

This study examined associations of psychological characteristics and sexual behavior with types of reasons for episodes of sexual intercourse among youth. After completing a baseline assessment, 62 adolescents (47 female) used a handheld computer to report when they had sex as soon as possible after the event as well as in response to random signals. Youth indicated for each sex event the main reason, categorized as intimacy/desire, external, affect management, and other; analyses were restricted to sex with a main partner (234 events). Baseline sexual behavior was not related to reasons for sex. Higher anxiety was associated with external reasons for sex; younger age and lower self-esteem were associated with affect management reasons. Female youth with higher impulsiveness reported more external reasons and fewer intimacy/desire reasons. Among male youth, lower self-esteem was associated with intimacy/desire reasons, but lower depression was associated with affect management reasons. These findings may aid health care providers and researchers in understanding the differences in young people's motivations for sex.  相似文献

Disasters provide opportunities to study the social and economic dimensions of large-scale shifts. Drawn by the surge in demand for low-skill construction workers in the aftermath of Hurricane Katrina in 2005, Latino immigrants represented a substantial share of the New Orleans reconstruction workforce. Scholars, however, have yet to examine how the increased presence of immigrants affected U.S.-born workers in New Orleans. In this analysis, we investigate how the influx of Latino immigrant construction workers shaped the demographic composition and occupational-wage structure of the New Orleans construction sector. Using IPUMS-U.S.A. data from the 2000 and 2006–2010 periods for the New Orleans MSA, we employ logistic and multinomial logistic regression models to analyze a sample of 3,206 foreign-born Latinos, U.S.-born whites, U.S.-born blacks, and others employed in the construction industry. Our analysis indicates that the probability of U.S.-born workers being employed in construction remained stable from the pre- to post-storm period, even as we find evidence of an emerging immigrant employment niche in the post-Katrina construction industry. After the storm, however, Latino immigrants were much more heavily concentrated in occupations at the bottom end of the construction industry’s wage structure, while the relative position of U.S.-born workers improved across the two periods. Together, these findings show that disasters, like other structural shifts, can yield the conditions that produce immigrant employment niches. Moreover, our results indicate that while employment niches provide economic opportunities for the foreign-born, they can also intensify the disadvantage experienced by immigrant workers.  相似文献

Much of what is known about emotions and sexuality explores the relationship enhancing qualities of positive affect. This research extends the current literature by focusing on the association between negative feelings and sexual thoughts and experiences in the context of close relationships, controlling for the effect of positive feelings. Specifically, the unique effects of daily negative feelings toward one's partner in general and specific negative feelings (i.e., anger, anxiety, and sadness) on the sexual experience of heterosexual, gay male, and lesbian relationships were explored. Participants completed an initial questionnaire followed by daily diary measures for 14 consecutive days. Positive feelings were positively associated with sexual variables as expected. Negative feelings were associated with increases in sexual behaviors for heterosexual men and women and gay men, but not lesbian women. Sadness showed a unique positive association with arousal, lust, wanted sexual behavior, and sexual behavior for heterosexual men and women and gay men, but not lesbian women. Neither anger nor anxiety was uniquely associated with the sexual experience for heterosexual or same-sex couples.  相似文献
