This study was part of a larger project directed by C. E. Osgood and J. C. Nunally of the University of Illinois, conducted under a grant from the National Institute of Mental Health. It is especially interesting, not only because of the current controversy over television program control, but for the light it throws on the operation of the network departments charged with the censorship function. 相似文献
The purpose of this article was to examine the validity of self-reported pedometer steps/day. Forty-seven participants were provided a New Lifestyles NL-2000 (NL-2000; Lees Summit, MO, USA) pedometer and a physical activity (PA) diary for 3 weeks, but not informed of the data-storing capabilities. For weeks 2 and 3, each participant was given a step goal of 3,000 steps/day above week 1 average. A 2 × 3 repeated measures analysis of variance (ANOVA) was used to examine differences between reported steps/day. Bland–Altman plots assessed the mean bias and limits of agreement between reporting methods. Mean self-reported and NL-2000 steps/day were 9,264 ± 3,555 and 8,971 ± 3,590 steps/day (n = 26, p > .05). Mean biases were 216 ± 1,753 (week 1), –506 ± 1,355 (week 2), and –590 ± 1,360 (week 3) steps/day. Negative mean bias values indicate higher self-reported steps/day. Mean steps/day were similar between recording methods, but large differences were observed among individuals, suggesting self-reported steps/day may be valid for PA research at the population level, but not the individual level. 相似文献
Purpose: This paper reports the results of survey research conducted with tribal producers between 2011 and 2012 on 19 of the largest American Indian reservations in Idaho, Nevada, North Dakota, Oregon, South Dakota, and Washington. The purpose of the research was to identify potential barriers to sustainable agriculture on reservation lands. This article reports the results of this research in an effort to promote Extension professionals' understanding of these barriers, which may help to improve outreach programs on American Indian reservations. Understanding the obstacles to sustaining agriculture that American Indian tribes face may inform international agricultural outreach efforts to increase food security targeting indigenous and tribal peoples worldwide.
Design/Methodology/Approach: American Indian agricultural producers comprised the study group. Study objectives included: (1) identify agricultural and natural resource issues of greatest concern to a self-selected sample of tribal agricultural producers on reservation lands; (2) evaluate access to Extension and other US Department of Agriculture outreach and assistance programs; and (3) evaluate the quality of these programs in terms of their relativity to tribal needs.
Findings: Study results indicate that tribal agricultural producers surveyed ranked 29 of 39 agricultural and natural resource issues as a concern. Similarly, they rated access to and quality of outreach programs as fair. Further, tribal producers operating on reservation trust land rated issues more severely than did tribal producers operating on fee simple lands.
Practical Implications: Results of this research will help Extension and other outreach professionals to understand the barriers indigenous and tribal peoples face in sustaining agricultural operations, particularly tribal groups living on federally reserved trust lands, such as American Indians. An increased understanding can inform agricultural policy-makers and outreach professionals in improving programs designed to increase agricultural sustainability, improve food security, enhance economic well-being and improve quality of life of indigenous and tribal peoples worldwide.
Originality/Value: This research provides important information to agricultural policy-makers and Extension professionals striving to sustain agricultural productivity and enhance food security with indigenous and tribal peoples. 相似文献
A compilation of results from three studies, conducted over a 5-year period, compare and contrast efficacy beliefs held by prospective and practicing teachers toward science and mathematics instruction. Particular attention is directed toward confidence and accountability factors. The theoretical background is derived from Bandura's model as well as the locus of control construct. Recommendations for teacher education programs are offered. 相似文献
ABSTRACTDespite questions about autoethnography in the ethnography and education research family, autoethnography is published in selective peer-reviewed journals in education and in the social and health sciences. Even critics of autoethnographic studies note their ‘rising acceptance in the past 15 years’ [Delamont, S. 2009. “The Only Honest Thing: Autoethnography, Reflexivity and Small Crises in Fieldwork.” Ethnography and Education 4 (1): 51–63]. However, there has been less effort towards qualitative meta-synthesis to learn what other insights might be gained from collections of studies. With the advent of meta-autoethnography [Ellis, C. 2009. Revision: Autoethnographic Reflections of Life and Work. Walnut Creek, CA: Left Coast Press], each author can find a way to synthesise her/his own autoethnographic works, however, synthesising autoethnographies of different authors has received no attention. This article examines a critical, systematic approach to the meta-ethnography of autoethnographies and offers a worked example of the method using educational studies. 相似文献
Studies have acknowledged children not as climate change victims only, but also as climate change actors. However, only a few have addressed the preparatory stages of children as climate change actors. However, the few studies that addressed these preparatory stages gave attention only to the roles of schools and government agencies without adequate attention to that of parents. This article therefore attempts to discuss the role of eco-parenting in building mitigation and adaptation capacities in children. Relying on the authoritative parenting model, the article avers that eco-parenting can have significant effects on children's ability to protect the environment, mitigate, and adapt to climate change impacts. 相似文献
Qualitative studies of the teacher labor market suggest that problems and remedies generated by quantitative research fail to capture the most dynamic variables which are affecting the supply and demand of public school teachers. For example, quantitative research has not accounted for (1) the continual exiting and reentering of urban teachers, (2) the considerable bifurcation between urban and rural teacher labor markets as reflected in teacher mobility and cultural economic opportunities, (3) local definitions of labor market needs and teacher quality, and (4) the demanding and stressful working conditions of teaching, which are having a systemic and adverse effect on the occupation. 相似文献
