Real-Life Dilemmas Make Learning Fun
No full textThis archival publication may not reflect current scientific knowledge or recommendations. Current information available from the University of Minnesota Extension: https://www.extension.umn.edu.Decision cases are a valuable, participatory learning tool. Youth enter the process with prior experiences and knowledge on which to build a new understanding of subject matter. The decision case experience encourages life skill development while delivering new subject matter. Decision cases encourage the development of problem-solving and decision-making skills through practice, and positive and enjoyable for youth. The effectiveness of decision case experiences in meeting instructional goals can be greatly enhanced by skilled facilitators.Dunrud, Tammy; Reicks, Marla; Simmons, Steve. (1999).

Simply Good Eating Partners with the Head Start Program to Improve Health and Nutrition Using Lessons in a Box: Comparing Two Years of Data.
No full textThe program objective was to compare the effectiveness of targeted nutrition education for preschool children in changing eating and physical activity behaviors in two youth groups. Data were collected from preschoolers attending Head Start programs during years 2011 (n=460) and 2012 (n=350) in nine counties in South Central Minnesota.
The Lessons in a Box program was delivered through the Simply Good Eating program. The lessons focused on good nutrition, food safety and physical activity.
Parents reported child eating behaviors, physical activity, family food security, food intake and demographic information. Evaluation data from independent samples during 2011 and 2012 included changes in key outcomes for children, and pre- and post-assessment childrens’ body mass index percentiles. The Lessons in a Box program was most beneficial for participating youth who fell outside of the healthy weight category and where the parents of participating youth were concerned about youth eating behaviors.Kunkel, Kelly; Hurtado, G.

Effects of methionine deficiency and ethanol ingestion on acetaminophen metabolism in mice
No full textThe interaction of the effect of dietary methionine (met) deficiency on the maintenance of hepatic glutathione (GSH) concentrations and the effect of chronic ethanol (EtOH) ingestion on the activity of the hepatic microsomal oxidation system were studied in relation to acetaminophen (ACAP) metabolism in mice. In the first study, adult, male mice were fed a diet that provided approximately one-half of the met requirement for 4 weeks and given a 15% EtOH solution as the sole source of drinking water in a 2 x 2 factorial design. The extent of ACAP-induced hepatotoxicity was greater in the met deficient mice, as shown by a reduced median lethal time following a lethal dose of ACAP and an increase in plasma glutamic-oxaloacetic transaminase (PGOT) activity following a sublethal dose. A more marked increase in PGOT activity was seen as a result of the interaction of met deficiency and EtOH consumption. Initial GSH levels were decreased and depletion following ACAP injection was greater in the met deficient groups. In the second study, mice were pair-fed an EtOH-containing liquid diet for 4 weeks that provided 46 or 100% of the met requirement in a 2 x 2 factorial design. There was an increase in hepatic microsomal protein content, relative liver weight, and hepatic microsomal aniline hydroxylase activity in the EtOH-fed groups indicating induction of microsomal oxidation by EtOH. Serum inorganic sulfate, hepatic free met, and GSH concentrations were decreased following a 300 mg/kg BW i.p. dose of ACAP. As in the first study, GSH depletion was greater in the met-deficient mice. The difference between the extent of ('35)S-met and ('14)C-methyl-met incorporation into hepatic proteins did not reflect differences in the hepatic transsulfuration pathway activity due to met deficiency. HPLC analysis of urinary ACAP conjugates showed a decrease in the amount of ACAP-sulfate conjugate excreted in the met deficient mice and an increase in excretion of ACAP sulfate and mercapturic acid derivatives by the EtOH-fed mice. These findings indicate that met deficiency compromises ACAP disposition in the mouse resulting in greater ACAP-induced hepatotoxicity and that chronic EtOH consumption may potentiate this effect by causing an increase in the formation of activated ACAP.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
