Application of Lortie’s Apprenticeship of Observation Model: Evidence of Iowa Teaching Standards with Amish School Teachers

Classroom educators are held to standards of teaching and learning throughout their professional careers. The standards are the expectations laid out by the national and state levels to determine how and why teachers should teach the way they do to increase student achievement (NBPTS, 2016; State of Iowa Department of Education, 2019; CCSSO, 2013). The teaching standards in Iowa align with pedagogy, instruction, and professionalism (State of Iowa Department of Education, 2019). Some educators learn how to become teachers through their post-secondary education courses. Those teachers who are part of the Amish community do not follow a traditional path to becoming an educator within the Amish school system. Their preservice learning and teaching requirements are much different, which is the focus of this research, as they have no post-secondary formal education on how to be an educator. The intent of this qualitative study was to understand if Amish teachers, without any formal post-secondary education, were able to show evidence of the Iowa Teaching Standards within their teaching instruction. Classroom observations were conducted and evidence was collected that show which standards were being implemented. The secondary part of this study is to understand how these Amish teachers were able to know how to be teachers in the Amish classroom. Structured interviews were conducted of Amish teachers and explored how Amish teachers learned to be instructors of the classroom while determining if their responses align with Dan C. Lortie’s (1975) Apprenticeship of Observation Model

Infrared radiometer for measuring thermophysical properties of wind tunnel models

An infrared radiometer is described which was developed to measure temperature rises of wind tunnel models undergoing transient heating over a temperature range of -17.8 C to 260 C. This radiometer interfaces directly with a system which measures the effective thermophysical property square root of rho ck. It has an output temperature fluctuation of 0.26 C at low temperatures and 0.07 C at high temperatures, and the output frequency response of the radiometer is from dc to 400 hertz

Estimating Atrazine Leaching in the Midwest

Data from seven Management Systems Evaluation Areas (MSEM) were used to test the sensitivity of a leaching model, PRZM-2, to a variety of hydrologic settings common in the Midwest. Atrazine leaching was simulated because the use of atrazine was prevalent in the MSEA studies and it frequently occurs in the region\u27s groundwater. Results of long-term simulations using regional and generalized input parameters produced ranks of leaching potential similar to those based on measurements. Short-term simulations used site-specific soil and chemical coefficients

Evolving Health Guidelines: How Do Consumers Fare While Science Marches On?

The press is replete with guidelines regarding preventive behaviors, such as exercise, vitamins, or food choices. Such guidelines may have unintended negative effects on consumers if later reversed. We report a study examining the effect of evolving health guidelines on consumers' initial response and critical "spillover" outcomes-consumers' faith in health guidelines in general and consumers' intention to perform related health behaviors not part of the guideline. We find that a guideline change from taking an action to inaction increases negative spillovers, consistent with omission bias and betrayal aversion. A follow-up experiment with policy implications for mitigating this undesired backlash will also be reported. [to cite]: Christine Moorman, Mary Frances Luce, and James R. Bettman (2008) SESSION OVERVIEW From news reports on the radio, television, internet, and magazines to focused health campaigns targeting susceptible groups, consumers are bombarded with health messages produced by ongoing medical studies, government agencies, for-profit health and insurance firms, and community and public health non-profits. A Google search of "health" produced 939,000,000 hits, "nutrition" produced 148,000,000 hits, and the specific phrases "health news" (6,140,000) and "health communications (651,000) produced a sizable number of hits. These numbers suggest that health messages are a fundamental part of the mosaic of communications consumers encounter every day and constitute a key component of campaigns designed to reduce morbidity and mortality. These numbers and other indicators also point to trends involving increased consumer responsibility for their own care and shifts in medical culture from paternalism towards informed consent. Despite these positive forces, most health communications produce low compliance and rather dismal results. Most health communications are undertaken to alter consumer action. Conventional wisdom is that if health communications are sufficiently informative and persuasive (increasing knowledge, efficacy, or motivation), then appropriate action will follow. This session's papers challenge this wisdom. The first two papers sharpen our understanding of how to use health communication to alter consumer action; the second two papers point to important downstream problems occurring after consumers are motivated to act. Anand Keller and Lehmann report a meta-analysis of 85 health communications studies. They find that message factors, not individual differences or context, dominate explanations of effectiveness. They also show important differences in effects on attitudes toward health behaviors and intentions to change behaviors that may critically influence whether we judge a campaign to be successful or not. Their research underscores the importance of conceptualizing and measuring consumer action (rather than simply consumer attitudes) as a key health communication goal. The second paper, by Anand Keller, extends this theme of the focal nature of consumer action by using mental simulation of healthpromoting actions as a focus of intervention. She challenges the current idea that hope and confidence produce more preventive health behaviors and suggests that increasing consumer anxiety is more effective by producing higher need for action taken to regain control. The third and fourth papers illustrate complementary difficulties in using health communication to alter action. Moorman, Luce, and Bettman argue that consumers may not always benefit from the evolving nature of health guidelines. As medical science sheds more light on the effect of healthy choices or treatment options, communications that initially advocate positive actions (e.g., take a vitamin supplement) but later reverse these suggestions may ultimately degrade consumers' view of health guidelines and decrease their likelihood of performing related health behaviors. Tanner shows that teens may provide inaccurate reports of actions related to risky behaviors when participating in the evaluation of community-based health programs. Inaccuracy is particularly problematic when teens are made aware of desirable health behaviors, when they believe their anonymity may not be protected, or when minimizing, not exaggerating, certain behaviors. Looking across papers, we see several emerging questions regarding the promise and pitfalls of using health communications to alter health behavior: (1) Do health communications work in the short and long-term? Unsurprisingly, numerous studies have assessed the impact of different communication strategies (e.g. level of fear arousal or framing) on subjects' attitudes toward and intentions with respect to various health behaviors. However, the large number of studies and the variability of the findings suggest a quantitative synthesis of this area would be beneficial. The purpose of this paper, therefore, is to assess the current state of knowledge in the field via metaanalysis. In particular, we wanted to identify the context, message and individual factors that increased attitudes and intentions to comply with the recommended health behaviors. For that purpose, we conducted a meta-analysis on data reported in 85 published and unpublished articles in the consumer research, psychology, health, and communications literatures

Two genetic differences between closely related zika virus strains determine pathogenic outcome in mice

Recent Zika virus (ZIKV) outbreaks and unexpected clinical manifestations of ZIKV infection have prompted an increase in ZIKV-related research. Here, we identify two strain-specific determinants of ZIKV virulence in mice. We found that strain H/PF/2013 caused 100% lethality in Ifnar1-/- mice, whereas PRVABC59 caused no lethality; both strains caused 100% lethality in Ifnar1-/- Ifngr1-/- doubleknockout (DKO) mice. Deep sequencing revealed a high-frequency variant in PRVABC59 not present in H/PF/2013: A G-to-T change at nucleotide 1965 producing a Val-to-Leu substitution at position 330 of the viral envelope (E) protein. We show that the V330 variant is lethal on both virus strain backgrounds, whereas the L330 variant is attenuating only on the PRVABC59 background. These results identify a balanced polymorphism in the E protein that is sufficient to attenuate the PRVABC59 strain but not H/PF/2013. The consensus sequences of H/PF/2013 and PRVABC59 differ by 3 amino acids, but these were not responsible for the difference in virulence between the two strains. H/PF/2013 and PRVABC59 differ by an additional 31 noncoding or silent nucleotide changes. We made a panel of chimeric viruses with identical amino acid sequences but nucleotide sequences derived from H/PF/2013 or PRVABC59. We found that 6 nucleotide differences in the 3= quarter of the H/PF/ 2013 genome were sufficient to confer virulence in Ifnar1-/- mice. Altogether, our work identifies a large and previously unreported difference in virulence between two commonly used ZIKV strains, in two widely used mouse models of ZIKV pathogenesis (Ifnar1-/- and Ifnar1-/- Ifngr1-/- DKO mice)

Perceived Similarity and Relationship Success among Dating Couples: An Idiographic Approach

This study utilized an idiographic approach to investigate the relation between similarity on valued characteristics and relationship success. College students (N = 247) rated their current romantic partner on perceived similarity in personality, attitudes, interests, and religious affiliation; the importance of similarity in these dimensions; and relationship satisfaction. Relationship status was assessed 6 weeks later. Results revealed significant similarity by importance interactions for religion and interests in predicting satisfaction. Participants with high perceived similarity in religion or interests reported greater satisfaction than did their low similarity counterparts, but only to the extent that they rated this type of similarity as being important to them. Similar results were found for attitudes in predicting Time 2 outcomes
