The CREATE Approach to Primary Literature Shifts Undergraduates' Self-Assessed Ability to Read and Analyze Journal Articles, Attitudes about Science, and Epistemological Beliefs

The C. R. E. A. T. E. (Consider, Read, Elucidate hypotheses, Analyze and interpret data, Think of the next Experiment) method uses intensive analysis of primary literature in the undergraduate classroom to demystify and humanize science. We have reported previously that the method improves students' critical thinking and content integration abilities, while at the same time enhancing their self-reported understanding of "who does science, and why." We report here the results of an assessment that addressed C. R. E. A. T. E. students' attitudes about the nature of science, beliefs about learning, and confidence in their ability to read, analyze, and explain research articles. Using a Likert-style survey administered pre- and postcourse, we found significant changes in students' confidence in their ability to read and analyze primary literature, self-assessed understanding of the nature of science, and epistemological beliefs (e. g., their sense of whether knowledge is certain and scientific talent innate). Thus, within a single semester, the inexpensive C. R. E. A. T. E. method can shift not just students' analytical abilities and understanding of scientists as people, but can also positively affect students' confidence with analysis of primary literature, their insight into the processes of science, and their beliefs about learning.NSFNSF CCLI/TUES 0311117, 0618536, 1021443Molecular Bioscience

How Do Adolescents Spell Time Use?

We investigate how household disadvantage affects the time use of 15-18 year-olds using 2003-2006 data from the American Time Use Survey. Applying competing-risk hazard models, we distinguish between the incidence and duration of activities and incorporate the daily time constraint. We find that teens living in disadvantaged households spend less time in non-classroom schooling activities than other teens. Girls spend some of this time in work activities, suggesting they are taking on adult roles. However we find more evidence of substitution into unsupervised activities, suggesting that it may be less structured environments that reduce educational investment.event history models, adolescence, time use

"Parental Child Care in Single Parent, Cohabiting, and Married Couple Families: Time Diary Evidence from the United States and the United Kingdom"

This study uses time diary data from the 2003 American Time Use Survey and the United Kingdom Time Use Survey 2000 to examine the time that single, cohabiting, and married parents devote to caring for their children. Time spent in market work, in child care as a primary activity, and in child care as a passive activity are jointly modeled using a correlated, censored regression model. Separate estimates are provided by gender, by country, and by weekend/weekday day. We find no evidence that these time allocation decisions differ for cohabiting and married parents, but there is evidence that single persons allocate time differently - as might be expected, given different household time constraints. In the U.S. single fathers spend significantly more time in primary child care on weekdays and substantially less time in passive child care on weekends than their married or cohabiting counterparts, while in the UK single fathers spend significantly more time in passive child care on weekdays. Single fathers in each country report less time at work on weekdays than their married or cohabiting counterparts. In the U.S., single mothers work more than married or cohabiting mothers on weekdays, while single mothers in the United Kingdom work less than married or cohabiting mothers on all days.

Growth or decline in the Church of England during the decade of Evangelism: did the Churchmanship of the Bishop matter?

The Decade of Evangelism occupied the attention of the Church of England throughout the 1990s. The present study employs the statistics routinely published by the Church of England in order to assess two matters: the extent to which these statistics suggest that the 43 individual dioceses finished the decade in a stronger or weaker position than they had entered it and the extent to which, according to these statistics, the performance of dioceses led by bishops shaped in the Evangelical tradition differed from the performance of dioceses led by bishops shaped in the Catholic tradition. The data demonstrated that the majority of dioceses were performing less effectively at the end of the decade than at the beginning, in terms of a range of membership statistics, and that the rate of decline varied considerably from one diocese to another. The only exception to the trend was provided by the diocese of London, which experienced some growth. The data also demonstrated that little depended on the churchmanship of the diocesan bishop in shaping diocesan outcomes on the performance indicators employed in the study

Ethics review: Dark angels – the problem of death in intensive care

Critical care medicine has expanded the envelope of debilitating disease through the application of an aggressive and invasive care plan, part of which is designed to identify and reverse organ dysfunction before it proceeds to organ failure. For a select patient population, this care plan has been remarkably successful. But because patient selection is very broad, critical care sometimes yields amalgams of life in death: the state of being unable to participate in human life, unable to die, at least in the traditional sense. This work examines the emerging paradox of somatic versus brain death and why it matters to medical science

Riparian Meadow Response to Modern Conservation Grazing Management.

Riparian meadows occupy a small proportion of the public lands in the western United States but they provide numerous ecosystem services, including the production of high-quality forage for livestock grazing. Modern conservation management strategies (e.g., reductions in livestock stocking rates and adoption of new riparian grazing standards) have been implemented to better balance riparian conservation and livestock production objectives on publicly managed lands. We examined potential relationships between long-term changes in plant community, livestock grazing pressure and environmental conditions at two spatial scales in meadows grazed under conservation management strategies. Changes in plant community were not associated with either livestock stocking rate or precipitation at the grazing allotment (i.e., administrative) scale. Alternatively, both grazing pressure and precipitation had significant, albeit modest, associations with changes in plant community at the meadow (i.e., ecological site) scale. These results suggest that reductions in stocking rate have improved the balance between riparian conservation and livestock production goals. However, associations between elevation, site wetness, precipitation, and changes in plant community suggest that changing climate conditions (e.g., reduced snowpack and changes in timing of snowmelt) could trigger shifts in plant communities, potentially impacting both conservation and agricultural services (e.g., livestock and forage production). Therefore, adaptive, site-specific management strategies are required to meet grazing pressure limits and safeguard ecosystem services within individual meadows, especially under more variable climate conditions

Promoting Engaged Scholarship Among Undergraduate University Students

The School Research Partnership (SRP) is an engaged scholarship program that promotes collaboration among undergraduate students, community partners, and university advisors. In this case study, we describe the Research Consultation Project (RCP), an undergraduate student independent study project that uses a community-based research approach to connect students, faculty, and community partners to help address critical societal issues. In the RCP, undergraduate students function as research consultants for representatives of local school districts or leaders of other community agencies and organizations such as a county commissioner or a nonprofit focused on post-secondary education opportunities for youth. The students work under the supervision of an advisor to address questions posed by the policymaker or practitioner. RCP meets different but complementary needs of the students and partners in ways that bridge student academic and applied learning, research, policy, and practice
