Postpartum Depression (PPD) affects approximately 9 - 20% of women. Many women with PPD go undiagnosed and/ or do not follow through on referrals for treatment. Although the most routinely prescribed treatments for PPD are antidepressant medication and psychotherapy, a significant number of women desire non-traditional options. This article provides a systematic review of ten recently published, randomized clinical trials in the examination of the effectiveness of complementary health approaches—the use of non-mainstream products and interventions—on PPD. A search of nine databases of the English language literature from the years 2006 to 2018 was performed. Review criteria included published work, utilization of randomized-controlled trials, and the use of a reliable and valid measurement tool to identify cases of PPD and monitor changes in symptom severity. The studies reviewed focused on the following interventions: aromatherapy, bright light therapy, electroacupuncture, infant massage, iron supplementation, mindfulness training, omega-3 fatty acids, saffron, and yoga. Outcomes demonstrate the feasibility and safety of these approaches, as well as varying degrees of effectiveness. While many were pilot studies using small sample sizes, the results are encouraging and substantiate the need for additional trials. Studies are summarized and limitations and implications for social work and future research are described. 相似文献

We use data from 1,755 college students to explore regional differences in adolescent gender norms. Students attending four
Northern universities and three Southern universities during the 1997–1998 academic year provided information on the ways
that adolescents in their high schools had gained prestige with peers. The analyses revealed significant gender differences
on fourteen of the fifteen most common avenues to prestige. Leading avenues to prestige for boys—sports, grades, and intelligence—did
not vary by region. Leading avenues to prestige for girls—physical attractiveness, grades, and intelligence—also did not vary
by region. However, consistent with the stronger emphasis on traditional moral views generally found in the South than the
North, regional differences were found for several other avenues to prestige.
Her work focuses on the effects of status transitions on intergenerational relations, social support networks, and marital
quality. In collaboration with Karl Pillemer, she is currently studying caregivers' social networks during bereavement, and
relations between caregivers and nursing home staff.
Her research interests include gender stratification, family, and education. Currently, she is a Research Associate on a project
examining health consequences of Mexican migration, funded primarily by the Hewlett Foundation (Co-PIs: Katherine M. Donato,
(LSU), and Shawn Malia Kanaiaupuni, University of Wisconsin-Madison). Her dissertation is entitled “Wages and Domestic Labor:

ABSTRACT The globalization of socio-economic relations is a central topic of discussion in both the general literature on economy and society and in the area of food and agriculture. Many maintain that we are in a transition from one era, termed Fordism, to another, called Global Post-Fordism. We use the case of two fisheries eco-labeling programs to inform discussions regarding the emergence of stabilizing socio-economic mechanisms in the Global Post-Fordist era. We argue that recent developments in the tuna-dolphin case, the first major experiment with eco-labeling in the fisheries industries, combined with the Marine Stewardship Council, an initiative designed to regulate and certify a system of global “sustainable fisheries” through an eco-labeling program, provide valuable insights into the ideological and organizational structure of salient global actors in the Post-Fordist era. The discussion addresses (1) the contested terrain within the “North” and between the “North” and the “South” regarding eco-legislation to regulate the global fisheries; (2) the fracturing of the environmental movement into “mainstream” and “grassroots” camps and the resulting inability to maintain a coordinated agenda to counter the globalization project; and (3) the emergence of new forms of supranational state-like regulatory mechanisms that combine science with free trade and environmental ideals and propose to resolve the global fisheries crises by providing sustainable socio-economic coordination. We conclude that the emergence of these supra-national state-like NGOs raises important implications for the sovereignty of nation-states and democratic action on the part of subordinate groups opposed to the globalization project. 相似文献

Researchers and practitioners embarked on a collaborative venture to develop, implement, and evaluate a career intervention program for 7th grade students who were at-risk for vocational underachievement. Students participating in the Career Horizons Program demonstrated enhanced confidence in performing tasks related to investigating, selecting, and implementing a career choice. They also considered a greater number of careers and selected those that were congruent with their interests. No change was found in confidence regarding degree of self-knowledge. Suggestions are provided for improving on the development and evaluation of career exploration programs to enhance career self-efficacy and broaden the career horizons of students in at-risk environments. 相似文献

The conservation of freshwater is of both global and national importance, and in the United States, agriculture is one of the largest consumers of this resource. Reduction of the strain farming puts on local surface or groundwater is vital for ensuring resilience in the face of climate change, and one possible option is to irrigate with a combination of freshwater and reclaimed water from municipal wastewater treatment facilities. However, this wastewater can contain pathogens that are harmful to human health, such as Legionella pneumophila, which is a bacterium that can survive aerosolization and airborne transportation and cause severe pneumonia when inhaled. To assess an individual adult's risk of infection with L. pneumophila from a single exposure to agricultural spray irrigation, a quantitative microbial risk assessment was conducted for a scenario of spray irrigation in central Illinois, for the growing seasons in 2017, 2018, and 2019. The assessment found that the mean risk of infection for a single exposure exceeded the safety threshold of 10–6 infections/exposure up to 1 km from a low-pressure irrigator and up to 2 km from a high-pressure irrigator, although no median risk exceeded the threshold for any distance or irrigator pressure. These findings suggest that spray irrigation with treated municipal wastewater could be a viable option for reducing freshwater consumption in Midwest farming, as long as irrigation on windy days is avoided and close proximity to the active irrigator is limited. 相似文献

This paper outlines a cause-of-death classification system applicable to nineteenth-century English-language death data. Consisting
of 32 categories, this system combines aspects of William Farr’s nosology, developed in nineteenth-century Britain, and the
modern International Classification of Diseases. It is sufficiently broad for meaningful categories to be created for analytical
purposes, but specific enough for particular cause-of-death trends and patterns to be traced. Individual-level death registration
data from the British colony of Tasmania, 1838–1899, are used to demonstrate the application of this classification system.
The paper describes the history of recording causes of death in nineteenth-century Tasmania and discusses several problems
particular to nineteenth-century cause-of-death data. The benefits and disadvantages of three existing nosologies, Farr’s,
Preston’s and the International Classification of Diseases, are considered with reference to nineteenth-century data. The
final sections outline the data and method, and discuss an application of the classification system developed for cause-specific
child mortality in nineteenth-century Tasmania. 相似文献
