Redefining Full-Time in College: Evidence on 15-Credit Strategies

ERIC Educational Resources Information Center

Klempin, Serena

2014-01-01

Because federal financial aid guidelines stipulate that students must be enrolled in a minimum of 12 credits per semester in order to receive the full amount of aid, many colleges and universities define full-time enrollment as 12 credits per semester. Yet, if a student takes only 12 credits each fall and spring term, it is impossible to complete…

Conceptual astronomy. II. Replicating conceptual gains, probing attitude changes across three semesters

1999-10-01

We report on a long-term, large-scale study of a one-semester, conceptually based, introductory astronomy course with data from more than 400 students over three semesters at the University of New Mexico. Using traditional and alternative assessment tools developed for the project, we examined the pre- and postcourse results for Fall 1994, Spring 1995, and Fall 1995. We find our results are robust: novice students show large, positive gains on assessments of conceptual understanding and connected understanding of the knowledge structure of astronomy. We find no relationship between course achievement and completion of prior courses in science or math; we do find a small to moderate relationship between students' science self-image and course achievement. Also, we detect little change over each semester in students' mildly positive incoming attitudes about astronomy and science.

Benden, Mark E.; Zhao, Hongwei; Jeffrey, Christina E.; Wendel, Monica L.; Blake, Jamilia J.

2014-01-01

Due to the increasing prevalence of childhood obesity, the association between classroom furniture and energy expenditure as well as physical activity was examined using a standing-desk intervention in three central-Texas elementary schools. Of the 480 students in the 24 classrooms randomly assigned to either a seated or stand-biased desk equipped classroom, 374 agreed to participate in a week-long data collection during the fall and spring semesters. Each participant’s data was collected using Sensewear® armbands and was comprised of measures of energy expenditure (EE) and step count. A hierarchical linear mixed effects model showed that children in seated desk classrooms had significantly lower (EE) and fewer steps during the standardized lecture time than children in stand-biased classrooms after adjusting for grade, race, and gender. The use of a standing desk showed a significant higher mean energy expenditure by 0.16 kcal/min (p < 0.0001) in the fall semester, and a higher EE by 0.08 kcal/min (p = 0.0092) in the spring semester.

Carmack, Gay Lynn Dickinson

2000-10-01

This two-part quasi-experimental repeated measures study examined whether computer simulated experiments have an effect on the problem solving skills of high school biology students in a school-within-a-school magnet program. Specifically, the study identified episodes in a simulation sequence where problem solving skills improved. In the Fall academic semester, experimental group students (n = 30) were exposed to two simulations: CaseIt! and EVOLVE!. Control group students participated in an internet research project and a paper Hardy-Weinberg activity. In the Spring academic semester, experimental group students were exposed to three simulations: Genetics Construction Kit, CaseIt! and EVOLVE! . Spring control group students participated in a Drosophila lab, an internet research project, and Advanced Placement lab 8. Results indicate that the Fall and Spring experimental groups experienced significant gains in scientific problem solving after the second simulation in the sequence. These gains were independent of the simulation sequence or the amount of time spent on the simulations. These gains were significantly greater than control group scores in the Fall. The Spring control group significantly outscored all other study groups on both pretest measures. Even so, the Spring experimental group problem solving performance caught up to the Spring control group performance after the third simulation. There were no significant differences between control and experimental groups on content achievement. Results indicate that CSE is as effective as traditional laboratories in promoting scientific problem solving and that CSE is a useful tool for improving students' scientific problem solving skills. Moreover, retention of problem solving skills is enhanced by utilizing more than one simulation.

Background. The purpose of this study was to examine the effect of a 12-week summer break on school day physical activity and health-related fitness (HRF) in children from schools receiving a Comprehensive School Physical Activity Program (CSPAP). Methods. Participants were school-aged children (N = 1,232; 624 girls and 608 boys; mean age = 9.5 ± 1.8 years) recruited from three low-income schools receiving a CSPAP. Physical activity and HRF levels were collected during the end of spring semester 2015 and again during the beginning of fall semester 2015. Physical activity was assessed using the Yamax DigiWalker CW600 pedometer. HRF measures consisted of body mass index (BMI) and the Progressive Aerobic Cardiovascular Endurance Run (PACER). Results. Results from a doubly MANCOVA analysis indicated that pedometer step counts decreased from 4,929 steps in the spring to 4,445 steps in the fall (mean difference = 484 steps; P < 0.001; Cohen's d = 0.30) and PACER laps decreased from 31.2 laps in the spring to 25.8 laps in the fall (mean difference = 5.4 laps; P < 0.001; Cohen's d = 0.33). Conclusions. Children from schools receiving a CSPAP intervention had lower levels of school day physical activity and cardiorespiratory endurance following a 12-week summer break. PMID:28377791

2015-01-01

The purpose of the study was to evaluate bidirectional associations between peer acceptance and both emotion and effortful control during kindergarten (N = 301). In both the fall and spring semesters, we obtained peer nominations of acceptance, measures of positive and negative emotion based on naturalistic observations in school (i.e., classroom, lunch/recess), and observers’ reports of effortful control (i.e., inhibitory control, attention focusing) and emotions (i.e., positive, negative). In structural equation panel models, peer acceptance in fall predicted higher effortful control in spring. Effortful control in fall did not predict peer acceptance in spring. Negative emotion predicted lower peer acceptance across time for girls but not for boys. Peer acceptance did not predict negative or positive emotion over time. In addition, we tested interactions between positive or negative emotion and effortful control predicting peer acceptance. Positive emotion predicted higher peer acceptance for children low in effortful control. PMID:28348445

This short-term longitudinal study examined whether the association between bullying perpetration and later physical dating violence perpetration and mediators of that association (via anger, depression, anxiety, and social status), varied depending on level of bullying victimization. Differences have been noted between those who bully but are not victims of bullying, and those who are both bullies and victims. These differences may influence dating violence risk and the explanations for why bullying leads to dating violence. Data were from dating adolescents in three rural counties who completed self-administered questionnaires in the fall semester of grades 8-10 and again in the spring semester. The sample (N = 2,414) was 44.08% male and 61.31% white. Bullying perpetration in the fall semester predicted physical dating violence perpetration in the spring semester when there was no bullying victimization, but not when there was any bullying victimization. Bullying perpetration was positively associated with anger at all levels of bullying victimization and with social status when there was no or low amounts of victimization; it was negatively associated with social status at high levels of victimization. Bullying victimization was positively associated with anger, depression, and anxiety at all levels of bullying perpetration. Anger mediated the association between bullying perpetration and dating violence, regardless of level of victimization; depression, anxiety, and social status did not mediate the association at any level of bullying victimization. The findings have implications for dating violence prevention efforts and for future research on the link between bullying and dating violence. © 2015 Wiley Periodicals, Inc.

Paschall, Mallie J.; Antin, Tamar; Ringwalt, Christopher L.; Saltz, Robert F.

2011-01-01

Objective: AlcoholEdu for College is a 2- to 3-hour online course for incoming college freshmen. This study was the first multicampus trial to examine effects of AlcoholEdu for College on alcohol-related problems among freshmen. Method: Thirty universi participated in the study. Fifteen were randomly assigned to receive AlcoholEdu, and the other 15 were assigned to the control condition. AlcoholEdu was implemented by intervention schools during the summer and/or fall semester. Cross-sectional surveys of freshmen were conducted at each university beginning before the intervention in spring 2008/2009; post-intervention surveys were administered in fall 2008/2009 and spring 2009/2010. The surveys included questions about the past-30-day frequency of 28 alcohol-related problems, from which we created indices for the total number of problems and problems in seven domains: physiological, academic, social, driving under the influence/riding with drinking drivers, aggression, sexual risk taking, and victimization. Multilevel Poisson regression analyses were conducted to examine intent-to-treat and dosage effects of AlcoholEdu for College on these outcomes. Results: Multilevel intent-to-treat analyses indicated significant reductions in the risk for past-30-day alcohol problems in general and problems in the physiological, social, and victimization domains during the fall semester immediately after completion of the course. However, these effects did not persist in the spring semester. Additional analyses suggested stronger AlcoholEdu effects on these outcomes at colleges with higher rates of student course completion. No AlcoholEdu effects were observed for alcohol-related problems in the other four domains. Conclusions: AlcoholEdu for College appears to have beneficial short-term effects on victimization and the most common types of alcohol-related problems among freshmen. Universities may benefit the most by mandating AlcoholEdu for College for all incoming freshmen and by implementing this online course along with environmental prevention strategies. PMID:21683046

2018-02-02

Depression and health-related quality of life (HRQOL) are major concerns affecting veterinary students' well-being. Shorter versions of instruments to assess depression and HRQOL are timesaving and preferable. To the authors' knowledge there are no studies available that assess HRQOL in veterinary students. The objectives of this study were to screen veterinary students for depression during two semesters using a 2-item Primary Care Evaluation of Mental Disorders Procedure Health Questionnaire (PRIME-MD PHQ), and to assess HRQOL over two semesters using the Optum Short Form-8 (SF-8) Health Survey. A cohort of 273 students from two classes were invited to complete the PRIME-MD PHQ and the SF-8 survey during the fall semester of their first year, and again in the spring semester of the second year. Descriptive statistics, factor analysis, multiple regression, and logistic regression were used to perform data analysis. The proportion of students with symptoms of depression was high, ranging from 37.4% to 56.8% between the two classes. The SF-8 survey indicated a mental component summary (MCS) score of <50, indicating poor mental health for both classes, whereas the physical component summary (PCS) was >50, suggesting good physical health. Female students (p=.043) had low MCS scores compared to males. Students from both classes had lower MCS scores in spring compared to fall (p=.019). The PRIME-MD PHQ and the SF-8 were acceptable instruments for assessing depression and HRQOL in veterinary students, respectively.

Dir, Allyson L; Riley, Elizabeth N; Cyders, Melissa A; Smith, Gregory T

2018-02-06

Sexual assault is a major public health concern and college women are four times more likely to experience sexual assault than any other group. We investigated whether sexting is a mechanism by which alcohol use increases risk for college women to be targeted for sexual assault. We hypothesized that sexting would mediate the relationship between problem drinking and sexual assault, such that drinking (T1 = beginning fall semester) would contribute to increased sexting (T2 = end fall semester), and in turn increase the risk of being targeted for sexual assault (T3 = end spring semester). Among 332 undergraduate women (M(SD)age = 19.15(1.69), 76.9% Caucasian), sexting (T2) predicted sexual assault (T3; b = 3.98, p = .05), controlling for baseline sexual assault (b = 0.82, p < .01). Further, sexting (T2) mediated the relationship between problem drinking (T1) and sexual assault (T3) (b = 0.04, CI[.004,.12]). Findings suggest that sexting is one mechanism through which drinking increases the risk of college women being targeted for sexual assault.

Teacher autonomy support reduces adolescent anxiety and depression: An 18-month longitudinal study.

Yu, Chengfu; Li, Xian; Wang, Shujun; Zhang, Wei

2016-06-01

Grounded in stage-environment fit theory, this study adopts a longitudinal design to examine the contribution of autonomy support from teachers to reducing adolescent anxiety and depression. A total of 236 Chinese adolescents (57.38% females, Mage = 14.34) completed questionnaires on teacher autonomy support, basic psychological needs satisfaction, school engagement, anxiety, and depression in the fall and spring semesters of their 7th and 8th grade years. The results showed that teacher autonomy support in the fall of 7th grade boosted basic psychological needs satisfaction in the spring of 7th grade; this, in turn, increased school engagement in the fall of 8th grade, which subsequently decreased anxiety and depression in the spring of 8th grade. These findings demonstrated the significant effect of teacher autonomy support on reducing adolescent anxiety and depression; furthermore, it highlighted the mediating roles of basic psychological needs satisfaction and school engagement in this relationship.

The authors aimed to determine if first-professional-year pharmacy students retain library literature search skills throughout the school year. Students (n = 61 consented) were given an identical seven-item quiz on basic library search skills prior to library instruction in the fall semester and at the end of the spring semester. There was no significant difference between median scores on the two quizzes, nor were any significant differences noted in subgroup analyses. Search competency may be retained to a higher degree if library instruction is moved later in the pharmacy curriculum when literature search skills are used more often.

Between Fall 1976 and Spring 1978, a study was conducted at Bronx Community College (BCC) to determine: (1) the effect of probationary status on students' subsequent academic performance as measured by grade point average (GPA); (2) whether a response-to-probation phenomenon continued beyond the semester of probation; and (3) the effects of…

A revolutionary approach to composite construction and flight management systems for small, general aviation airplanes

NASA Technical Reports Server (NTRS)

Roskam, Jan; Wenninger, ED

1992-01-01

The design studies for two composite general aviation airplanes are presented. The main consideration for both of the designs was to avoid the typical 'metal replacement' philosophy that has hindered the widespread use of composites in general aviation aircraft. The first design is for a low wing aircraft based on the Smith Aircraft Corporation GT-3 Global Trainer. The second aircraft is a composite version of the Cessna 152. The project was conducted as a graduate level design class under the auspices of the KU/NASA/USRA Advanced Design Program in aeronautics. The results obtained from the Fall semester of 1991 and the Spring semester of 1992 are presented.

Semester and Event-Specific Motives for Alcohol Use During Spring Break: Associated Protective Strategies and Negative Consequences

PubMed Central

Patrick, Megan E.; Lewis, Melissa A.; Lee, Christine M.; Maggs, Jennifer L.

2012-01-01

Motives surrounding alcohol use behavior are important for understanding college student drinking. However, no previous research has addressed how motives for and against drinking during specific events associated with high-risk drinking, such as Spring Break, may differ from motives for and against drinking during the regular semester. Further, we examine the extent to which semester and Spring Break motives are associated with alcohol use, protective behavioral strategies (PBS), and consequences. Participants were college students (N = 261; 55% women) who provided data both immediately prior to (Wave 1) and after (Wave 2) Spring Break. Fun/Social motives for drinking were greater for Spring Break, and Driving motives against drinking were lower for Spring Break, compared to semester drinking. Relax and Image motives for drinking and Physical/Behavioral motives for not drinking during Spring Break did not differ from semester motives. Spring Break motives for and against drinking were associated with total drinks, maximum drinks, PBS, and experienced negative consequences during Spring Break. Students’ specific motives regarding drinking during Spring Break predict high-risk drinking and may be utilized in creating salient event-specific interventions. PMID:23384451

Social Risk and Peer Victimization in Elementary School Children: The Protective Role of Teacher-Student Relationships.

PubMed

Elledge, L Christian; Elledge, Allison R; Newgent, Rebecca A; Cavell, Timothy A

2016-05-01

Children not accepted or actively rejected by peers are at greater risk for peer victimization. We examined whether a positive teacher-student relationship can potentially buffer these children from the risk of peer victimization. Participants were 361 elementary school children in the 4th or 5th grade. Peer-report measures were used to assess teacher-student relationship quality (TSRQ), social preference, and rejected sociometric status; peer victimization was assessed via self-, peer-, and teacher-reports. As expected, social preference assessed in the fall semester was a significant negative predictor of self- and peer-reported victimization measured in the spring, controlling for prior levels of peer victimization. TSRQ in the fall was not a significant unique predictor of self-, peer-, or teacher-reported victimization the following spring, controlling for fall victimization and social preference scores. We found a significant interaction between social preference and TSRQ in predicting self-, peer-, and teacher-reported peer victimization: Social preference significantly predicted peer victimization, but only for those children with relatively poor student-teacher relationships. Subgroup analysis revealed that children actively rejected by peers in the fall reported significantly less peer victimization in the spring (controlling for fall victimization scores) when their fall TSRQ scores were at or above the sample mean compared to rejected children whose TSRQ scores were low (i.e., < -0.5 SD below the mean). Findings offer preliminary support for the notion that teacher-student relationship quality can buffer children at social risk for continued peer victimization.

River-Based Experiential Learning: the Bear River Fellows Program

Rosenberg, D. E.; Shirley, B.; Roark, M. F.

2012-12-01

The Department of Civil and Environmental Engineering, Outdoor Recreation, and Parks and Recreation programs at Utah State University (USU) have partnered to offer a new, unique river-based experiential learning opportunity for undergraduates called the Bear River Fellows Program. The program allows incoming freshmen Fellows to experience a river first hand during a 5-day/4-night river trip on the nearby Bear River two weeks before the start of their first Fall semester. As part of the program, Fellows will navigate the Bear River in canoes, camp along the banks, interact with local water and environmental managers, collect channel cross section, stream flow, vegetation cover, and topological complexity data, meet other incoming freshmen, interact with faculty and graduate students, develop boating and leadership skills, problem solve, and participate as full members of the trip team. Subsequently, Fellows will get paid as undergraduate researchers during their Fall and Spring Freshman semesters to analyze, synthesize, and present the field data they collect. The program is a collaborative effort between two USU academic units and the (non-academic) division of Student Services and supports a larger National Science Foundation funded environmental modelling and management project for the lower Bear River, Utah watershed. We have advertised the program via Facebook and emails to incoming USU freshmen, received 35 applications (60% women), and accepted 5 Fellows into the program (3 female and 2 male). The river trip departs August 14, 2012. The poster will overview the Bear River Fellows Program and present qualitative and preliminary outcomes emerging from the trip and Fellows' work through the Fall semester with the field data they collect. We will also undertake more rigorous and longer longitudinal quantitative evaluation of Program outcomes (for example, in problem-solving and leadership) both in Spring 2013 and in subsequent 2013 and 2014 offerings of the program.

Student Understanding of Time in an Introductory Astronomy Laboratory

Traxler, A. L.; Batuski, D. J.; Comins, N. F.; Thompson, J. R.

2005-09-01

The astronomy lab at the University of Maine consists of discrete weekly lessons in which students work in small groups. Individual pretests and post-tests accompany each lesson. The lesson studied here covers the topic of time, including sidereal time, Apparent Solar Time, and time zones. The pretest consists of four multiple-choice questions, which are also administered after instruction as a post-test. In the fall 2004 semester, the pretest was rewritten to focus on some major conceptual components of the lab, while the lesson materials were not modified from previous years. Examination of class performance (n = 96) revealed no significant improvements in score from pre- to post-lesson. In the spring 2005 semester, the lesson was altered to incorporate the Starry Night software for simulating the sky instead of the celestial sphere models previously used. The goal of the change was to give students a more interactive environment for completing the laboratory exercise, which was otherwise altered as little as possible. Data from the spring semester show some gains on the pre/post-test questions covering sidereal time and Daylight Savings Time. Results to date have informed planned modifications to the lesson. A. L. T. was supported during this research by the University of Maine through a Provost Fellowship.

Students at the University of Wisconsin-Milwaukee Department of Agriculture undertook a series of studies of lunar habitats during the 1989 to 1990 academic year. Undergraduate students from architecture and mechanical and structural engineering with backgrounds in interior design, biology and construction technology were involved in a seminar in the fall semester followed by a design studio in the spring. The studies resulted in three design alternatives for lunar habitation and an integrated design for an early stage lunar outpost.

A mission to Mercury and a mission to the moons of Mars

NASA Technical Reports Server (NTRS)

1993-01-01

Two Advanced Design Projects were completed this academic year at Penn State - a mission to the planet Mercury and a mission to the moons of Mars (Phobos and Deimos). At the beginning of the fall semester the students were organized into six groups and given their choice of missions. Once a mission was chosen, the students developed conceptual designs. These designs were then evaluated at the end of the fall semester and combined into two separate mission scenarios. To facilitate the work required for each mission, the class was reorganized in the spring semester by combining groups to form two mission teams. An integration team consisting of two members from each group was formed for each mission team so that communication and exchange of information would be easier among the groups. The types of projects designed by the students evolved from numerous discussions with Penn State faculty and mission planners at the Lewis Research Center Advanced Projects Office. Robotic planetary missions throughout the solar system can be considered valuable precursors to human visits and test beds for innovative technology. For example, by studying the composition of the Martian moons, scientists may be able to determine if their resources may be used or synthesized for consumption during a first human visit.

Assessment of Factors that Influence the Recruitment of Majors from Introductory Geology Classes

NASA Astrophysics Data System (ADS)

Hoisch, T. D.; Bowie, J. I.

2009-12-01

In order to guide the formulation of strategies for recruiting undergraduates taking introductory geology courses into the geology program at Northern Arizona University, we surveyed 783 students in introductory geology classes and 23 geology majors in their junior and senior years. Our introductory courses (GLG100, Introduction to Geology; GLG101, Physical Geology; and GLG112, Geologic Disasters) typically enroll ~600 students each semester. The majority of students in these classes are non-majors who take them in order to satisfy a university general education requirement (called “Liberal Studies requirements” at NAU). A large proportion of these students are freshmen (51%) and sophomores (30%), and many have not yet decided on a major or are uncertain about the major they have chosen. Our analysis shows that ~7% of students in the introductory classes are possible candidates for recruitment. Although a small percentage, it represents a large number of individuals, in fact more than could be accommodated were they all to decide to major in geology. Influential factors that weigh in favor of majoring in geology include good employability, good salary potential, and opportunities for working outdoors, field work, observing nature, travel, and environmentally friendly employment. In addition, students view a career as a geologist as potentially the most fulfilling of the different science occupations (biologist, chemist, geologist, environmental scientist, physicist) and among the more environmentally friendly. However, students perceive geology to be the least difficult of the sciences, and geology occupations to be low-paying and low in prestige relative to the other sciences. These negative perceptions could be countered by providing data to introductory students showing the starting salaries of geologists in comparison to other science occupations, and by communicating the rigorous nature of the more advanced classes in the geology degree program. A preliminary finding of this study is that administering surveys may have the beneficial unintended consequence of inspiring students in introductory classes to reconsider their choice of major. From the Fall 2007 semester to the Spring 2008 semester, 14 of 573 introductory students or 2.4% continued into a geology course that can serve as the second course in the major, whereas from the Fall 2008 semester to the Spring 2009 semester, 24 of 609 students or 4.0% continued, a 67% increase in the rate of continuation. One possible explanation for the dramatic increase is that surveys were administered to students in the introductory classes in Fall 2008 but not in Fall 2007. If administering surveys was in fact the cause of the increase in the continuation rate, then we may have encountered a “Hawthorne effect;” that is, a situation in which the condition of being studied causes subjects to change their behavior. The process of taking the survey may have caused students to reconsider their choice of major, although this was not the intended purpose or design of the surveys.

The Sea Floor: A Living Learning Residential Community

2016-02-01

Living learning communities are collaborations between university housing and academic departments designed to enhance the overall student experience by integrating classroom/laboratory learning, student life and extracurricular activities. At Coastal Carolina University, the residential community associated with the Marine Science program is known as the Sea Floor. Students selected to become members of the Sea Floor remain "in residence" for two consecutive semesters. These students are first-time freshman that share a common course connection. This course is usually Introduction to Marine Science (MSCI 111) or MSCI 399s, which are one credit field/laboratory centered internships. The common course connection is designed so residents can establish and maintain an educational dialog with their peers. Activities designed to enhance the students' networking skills and educational and social development skills include monthly lunches with marine science faculty and dinner seminars with guest speakers from academia, industry and government. Additionally, each semester several activities outside the classroom are planned so that students can more frequently interact with themselves and their faculty and staff partners. These activities include field trips to regional aquariums, local boat trips that include water sample collection and analysis, and an alternative spring break trip to the Florida Keys to study the marine environment firsthand. The resident advisor that supervises the Sea Floor is usually a sophomore or junior marine science major. This provides the residents with daily communication and mentoring from a marine science major that is familiar with the marine science program and residence life. Assessment activities include: a university housing community living survey, student interest housing focus groups, fall to spring and fall to fall retention, and evaluation of program advisors and program activities.

The Impact of Cooperative Quizzes in a Large Introductory Astronomy Course for Non Science Majors

NASA Astrophysics Data System (ADS)

Zeilik, Michael; Morris, Vicky J.

In Astronomy 101 at the University of New Mexico, we carried out a repeated-items experiment on quizzes and tests to investigate the impact of cooperative testing. This trial was the only change in a reformed course format that had been refined over previous semesters. Our research questions were: Did cooperative quizzes result in gains for the class overall? Did these gains "stick" within the semester? In the spring and fall semesters of 2000, students took quizzes individually and in cooperative learning teams, and tests individually. Normalized gain, , on the quizzes averaged about 0.4, and effect size about 0.8 (approximately a 10% increase in class mean score). Repeating selected quiz items on a subsequent test demonstrated that the gain was sustained over a month in both semesters. In addition, we compared demographics of UNM students with those of the National Astronomy Diagnostic Test project. We found that UNM students are similar to the national sample, except in ethnicity (more Hispanic American, fewer White). Based on these results, we judge that our cooperative quiz strategy will likely succeed in other "Astro 101" classes.

Comet nucleus and asteroid sample return missions

NASA Technical Reports Server (NTRS)

1992-01-01

Three Advanced Design Projects have been completed this academic year at Penn State. At the beginning of the fall semester the students were organized into eight groups and given their choice of either a comet nucleus or an asteroid sample return mission. Once a mission had been chosen, the students developed conceptual designs. These were evaluated at the end of the fall semester and combined into three separate mission plans, including a comet nucleus same return (CNSR), a single asteroid sample return (SASR), and a multiple asteroid sample return (MASR). To facilitate the work required for each mission, the class was reorganized in the spring semester by combining groups to form three mission teams. An integration team consisting of two members from each group was formed for each mission so that communication and information exchange would be easier among the groups. The types of projects designed by the students evolved from numerous discussions with Penn State faculty and mission planners at the Johnson Space Center Human/Robotic Spacecraft Office. Robotic sample return missions are widely considered valuable precursors to manned missions in that they can provide details about a site's environment and scientific value. For example, a sample return from an asteroid might reveal valuable resources that, once mined, could be utilized for propulsion. These missions are also more adaptable when considering the risk to humans visiting unknown and potentially dangerous locations, such as a comet nucleus.

Effects of cooperative learning strategy on undergraduate kinesiology students' learning styles.

Meeuwsen, Harry J; King, George A; Pederson, Rockie

2005-10-01

A growing body of research supports cooperative learning as an effective teaching strategy. A specific cooperative learning strategy, Team-based Learning, was applied to a convenience sample of four undergraduate sophomore-level motor behavior courses over four semesters from Fall 2002 to Spring 2004 to examine whether this strategy would affect students' learning styles. The data from the Grasha-Reichmann Student Learning Style Scales indicated that this teaching strategy was associated with a significant decrease in the negative Avoidant and Dependent learning styles and an improvement in the positive Participant learning style.

Assessing the Impacts of a Hybrid ``Flipped'' Approach to University Physics.

Hughes, Chris; Paulson, Scott

2015-03-01

Over the course of several years, the physics faculty at James Madison University has been gradually reforming the introductory calculus-based physics sequence to a hybrid model using a ``flipped classroom'' approach. The content traditionally delivered during lecture was divided into approximately 150 short (5-10 minute) videos. For homework, students are assigned 3-5 videos to watch before each class session. These assignments are combined with in-class activities including gouger problem solving and the tutorials developed by the University of Washington group to provide the students with focused guidance on concepts and skills that students traditionally have left our classes not having mastered. For the fall semester course on mechanics, the Force Concept Inventory (FCI) was used to evaluate student outcomes. For the spring semester course on E&M and optics, the Conceptual Survey of Electricity and Magnetism (CSEM) was used. Student reaction to the course structure was generally positive though there were some complaints in the student evaluations at the end of each semester. However, a positive impact on student outcomes was observed based on the Hake gains on the FCI.

Objectives. To determine if a teaching assistant (TA) program for third-year pharmacy students (PY3s) improves confidence in teaching abilities. Additionally, 3 assessment methods (faculty, student, and TA self-evaluations) were compared for similarities and correlations. Methods. An application and interview process was used to select 21 pharmacy students to serve as TAs for the Pharmaceutical Care Laboratory course for 2 semesters. Participants' self-perceived confidence in teaching abilities was assessed at the start, midpoint, and conclusion of the program. The relationships between the scores were analyzed using 3 assessment methods. Results. All 21 TAs agreed to participate in the study and completed the 2 teaching semesters. The TAs confidence in overall teaching abilities increased significantly (80.7 vs 91.4, p <0.001). There was a significant difference between the three assessment scores in the fall ( p =0.027) and spring ( p <0.001) semesters. However, no correlation was found among the assessment scores. Conclusions. The TA program was effective in improving confidence in teaching abilities. The lack of correlation among the assessment methods highlights the importance of various forms of feedback.

Profiles of College Drinkers Defined by Alcohol Behaviors at the Week Level: Replication Across Semesters and Prospective Associations With Hazardous Drinking and Dependence-Related Symptoms

Fairlie, Anne M.; Maggs, Jennifer L.; Lanza, Stephanie T.

2016-01-01

Objective: Types of college drinkers have been identified using traditional measures (e.g., 12-month drinking frequency). We used an alternative multidimensional approach based on daily reports of alcohol behaviors to identify college drinker statuses, each with a unique behavioral profile. The current study aimed to (a) identify drinker statuses at the week level across four semesters, (b) examine the predictive utility of drinker status by testing associations with senior-year hazardous drinking and dependence symptoms, and (c) identify concurrent predictors (gender, drinking motivations, hazardous drinking, any dependence symptoms) of senior-year drinker status. We also compared the week-level drinker statuses with drinker statuses identified using traditional measures. Method: A multi-ethnic sample of U.S. college students completed 14-day bursts of daily web surveys across college (91%–96% completed ≥6 daily reports of the sampled week). Analyses focus on nine alcohol-related behaviors (including estimated blood alcohol concentration, pregaming, and drinking games) assessed daily in spring/sophomore year to fall/senior year and drinking motivations, hazardous drinking, and dependence symptoms assessed fall/senior year (n = 569; 56% women). Results: Four week-level drinker statuses were replicated across semesters: Nondrinker, Light Weekend, Heavy Weekend, and Heavy Frequent. Across semesters, drinker status was associated with senior-year hazardous drinking and any dependence symptoms. Senior-year fun/social motivations were also associated with senior-year drinker status. Differences in behavioral profiles between week-level drinker statuses and those identified using traditional measures were found. Conclusions: Replicable week-level drinker statuses were identified, suggesting consistency in possible types of drinking weeks. Drinker statuses were predictive of senior-year hazardous drinking and dependence symptoms. PMID:26751353

Essays in the Non-Science Major Astrobiology Course

D'Cruz, Noella L.

2014-06-01

The non-science major "Life in the Universe" class offers students many opportunities to explore topics such as whether or not to send manned missions to Mars, which jovian moon is a suitable candidate for harboring life, etc. Some of these topics are suited to being offered as projects. At Joliet Junior College, Joliet, IL, we offer this general education class every semester to around 40 students. We expect our students to complete three short essays in a semester, instead of doing one or two large projects. The essays enable students to be engaged more deeply with some aspects of the course than is usually possible in the classroom. Some of our essay topics are based on suggestions in the textbook, others have been developed by us. In this poster, we will report on the essay topics and the attitudes of our Fall 2013 and Spring 2014 students to such essays.

Comparison of Exams for Active Learning Technologies vs. Traditional Lectures

2017-01-01

George Mason University has first semester (PHYS-160) and second semester (PHYS-260) physics course which consist of two sections. One is a traditional lecture style format (TRAD) and the other is a newer format which is a take on the ``flipped'' classroom. This newer style is referred to as Active Learning with Technologies (ALT). This course style has been in place for several years and has been studied before within George Mason University for final grade differences. These studies suggested that the ALT sections performed better, but grade weighting consistency, test time, and test content were not strictly controlled. The purpose of this study is to cross-examine the performance of students in these different class formats during Fall 2016 (PHYS-260) and Spring 2015 (PHYS-160) on very nearly identical exams over identical test times while controlling for almost every variable.

Inquiring Minds Want to Know: Progress Report on SCALE-UP Physics at Penn State Erie

NASA Astrophysics Data System (ADS)

Hall, Jonathan

2008-03-01

SCALE-UP (Student Centered Activities for Large Enrollment University Programs) is a ``studio'' approach to learning developed by Bob Beichner at North Carolina State University. SCALE-UP was adapted for teaching and learning in the introductory calculus-based mechanics course at Penn State Erie, The Behrend College, starting in Spring 2007. We are presently doing quantitative and qualitative research on using inquiry-based learning with first year college students, in particular how it effects female students and students from groups that are traditionally under-represented in STEM fields. Using field notes of observations of the classes, focus groups, and the collection of quantitative data, the feedback generated by the research is also being used to improve the delivery of the course, and in the planning of adopting SCALE-UP to the second semester course on electromagnetism in the Fall 2008 semester.

This document presents the bas'c hardware design developed by the EE 499 class during the spring semester of the 1999-2000 academic year. This design covers the electrical components to supply power to the experiments, the computer software and interfaces to control the experiments, and the ground data processing to provide an operator interface. This document is a follow-on to the Payload Mission description document and the System Requirements document developed during the EE 498 class during the fall semester. The design activities are broken down by functional area within the structure. For each area, we give the requirements that need to be met and the design to meet the requirements. For each of these areas, a prototype selection of hardware and/or software was done by the class and the components assembled as part of the class to verify that they worked as intended.

Assessment of the benefits of a summer undergraduate research program for physics and chemistry majors

NASA Astrophysics Data System (ADS)

Hughes, Chris; MacDonald, Gina

2006-11-01

Presently at James Madison University, there are slightly more than 100 physics majors and 150 chemistry majors. Each summer, a significant fraction of these students participate in either the chemistry or interdisciplinary materials science Research Experiences for Undergraduates (REU) program on campus. This provides a large pool of students from which to draw data comparing the influence of undergraduate research on both classroom performance and attitudes toward science as a profession. By analyzing the grade point averages of chemistry and physics majors, we have shown slightly larger increases from spring semester to fall semester for students who participated in the REU than those who did not. We have also measured changes in attitudes using surveys of the students both at the beginning and at the end of the summer experience. An analysis of these surveys will be presented.

Plans of Implementation and Methods for Increasing Student Enrollment in the Earth Systems Science Course at Elizabeth City State University

NASA Astrophysics Data System (ADS)

Porter, W.

2001-12-01

This presentation reviews the experience of Elizabeth City State University (ECSU) in offering the Earth Systems Science (ESS) online course sponsored the Earth System Science Education Alliance (ESSEA) and how it relates to our plans to offer the course in the Spring Semester of 2002. The course was offered for the first time at ECSU during the Fall semester 2000. Eight students were enrolled in the course, which may not be considered a large number; however, we felt the administration of the course was successful because of the staff's learning experience. The small number is also a reflection of the nature of ECSU's primary recruitment region of northeastern North Carolina; this area is extremely rural with a smaller population, lower economic development, and fewer cultural amenities than most regions of the state. Our approach to this project is for a long-term effective offering of a course that is much needed, especially in this area of the state. The ultimate goal is to develop ESS as our online offering of courses in the Geoscience Department curriculum as to recruit students who might not have the opportunity to take college-level courses because of daytime work commitments and/or inaccessibility to a local college or university. A major component of ESS is its focus on problem-based learning built upon the life experiences of participating students. Having learned from the previous offering of the course, the following are objectives related to the Spring Semester 2002: 1. To get ESS to become a part of the Geoscience curriculum so that it will be listed on the schedule of classes for the Spring Semester 2002 and each succeeding semester; 2. To aggressively reach out to the public school teachers, especially in the recruitment region of ECSU in northeastern North Carolina, by using effective recruitment strategies; 3. To have an active and continuous communication with prospective students prior to and immediately after the enrollment, as well as being accessible to them during the entire period of the course; and 4. To have students focus on the problem-based aspect of the course as it relates to their life experiences. These objectives are designed to increase enrollment in the course as well as to enhance the retention of participating students.

Facilitating Learning in Large Lecture Classes: Testing the “Teaching Team” Approach to Peer Learning

PubMed Central

Lang, Sarah; Maas, Martha

2010-01-01

We tested the effect of voluntary peer-facilitated study groups on student learning in large introductory biology lecture classes. The peer facilitators (preceptors) were trained as part of a Teaching Team (faculty, graduate assistants, and preceptors) by faculty and Learning Center staff. Each preceptor offered one weekly study group to all students in the class. All individual study groups were similar in that they applied active-learning strategies to the class material, but they differed in the actual topics or questions discussed, which were chosen by the individual study groups. Study group participation was correlated with reduced failing grades and course dropout rates in both semesters, and participants scored better on the final exam and earned higher course grades than nonparticipants. In the spring semester the higher scores were clearly due to a significant study group effect beyond ability (grade point average). In contrast, the fall study groups had a small but nonsignificant effect after accounting for student ability. We discuss the differences between the two semesters and offer suggestions on how to implement teaching teams to optimize learning outcomes, including student feedback on study groups. PMID:21123696

To determine if traditional didactic lecture or the jigsaw learning method is more effective to teach the medication therapy management (MTM) core elements in a first year pharmacy course. Traditional didactic lecture and a pre-class reading assignment were used in the fall semester cohort, and the jigsaw method was used in the spring semester cohort. Jigsaw is a cooperative learning strategy requiring students to assume responsibility for learning, and subsequently teaching peers. The students were responsible for reading specific sections of the pre-class reading, and then teaching other students in small groups about their specific reading assignments. To assess potential differences, identical pre- and post-tests were administered before and after the MTM section. Additionally, grade performance on an in-class project and final exam questions were compared, and students were surveyed on perceptions of teaching method used. A total of 45 and 43 students completed both the pre- and post-test in the fall and spring (96% and 93% response rate), respectively. Improvement in post-test scores favored the traditional method (p = 0.001). No statistical differences were noted between groups with grade performance on the in-class project and final exam questions. However, students favored the jigsaw method over traditional lecture and perceived improvements in problem solving skills, listening/communication skills and encouragement of cooperative learning (p = 0.018, 0.025 and 0.031). Although students favored the jigsaw learning method, traditional didactic lecture was more effective for the pre- and post-knowledge test performance. This may indicate that traditional didactic lecture is more effective for more foundational content. Copyright © 2017 Elsevier Inc. All rights reserved.

Carey, Kate B; Durney, Sarah E; Shepardson, Robyn L; Carey, Michael P

2015-06-01

The purpose of this study was to document the point and cumulative prevalence of incapacitated rape (IR) and forcible rape (FR) among first-year college women. Female students (N = 483) completed a health questionnaire (1) on arrival on campus; (2) at the end of the fall semester; (3) at the end of the spring semester; and (4) at the end of the summer following their first year of college. Before entering college, 18% reported IR (attempted and/or completed), and 15% reported FR (attempted and/or completed). During the first year of college, 15% reported IR (attempted or completed) and 9% reported FR (attempted or completed). By the start of the second year (lifetime prevalence), 26% and 22% had experienced IR and FR (attempted or completed), respectively. Both incapacitated and forcible sexual assaults and rape have reached epidemic levels among college women. Interventions to address sexual violence on campus are urgently needed.

Enlund, Emmi; Aunola, Kaisa; Tolvanen, Asko; Nurmi, Jari-Erik

2015-08-01

This study investigated the dynamics between the causal attributions parents reported daily for their children's success in learning situations and parental positive emotions. The sample consisted of 159 mothers and 147 fathers of 162 first graders (83 girls, 79 boys; aged from 6 to 7 years, M = 7.5 years, SD = 3.6 months). Parents filled in a structured diary questionnaire concerning their causal attributions and emotions over 7 successive days in the fall semester and again over 7 successive days in the spring semester. Multilevel analyses showed that both parental causal attributions and positive emotions varied more within parents (between days over the week) than between parents. Furthermore, mothers' positive emotions on a certain day predicted their causal attributions on that same day rather than vice versa. The higher the level of positive emotions parents reported in a specific day, the more they used effort and ability as causal attributions for their offspring's success on that same day.

Garbee, Deborah D; Paige, John; Barrier, Kendra; Kozmenko, Valeriy; Kozmenko, Lyubov; Zamjahn, John; Bonanno, Laura; Cefalu, Jean

2013-01-01

The purpose of this study was to evaluate the efficacy of using crisis resource management (CRM) principles and high-fidelity human patient simulation (HFHPS) for interprofessional (IP) team training of students from undergraduate nursing, nurse anesthesia, medical, and respiratory therapy. IP education using simulation-based training has the potential to transform education by improving teamwork and communication and breaking down silos in education. This one-year study used a quasi-experimental design to evaluate students' acquisition and retention of teamwork and communication skills. A convenience sample consisted of 52 students in the fall semester, with 40 students returning in the spring. Mean scores increased after training, and skills were retained fairly well. Any loss was regained with repeat training in the spring. The results suggest that using CRM and HFHPS is an effective pedagogy for teaching communication and teamwork skills to IP student teams.

2017-07-01

Managed care pharmacy is a growing field, but there are still limited educational opportunities available in pharmacy school core curricula. Students often seek self-directed learning opportunities to further explore the field. To (a) evaluate practicality and effectiveness of a student-designed managed care pharmacy elective and (b) determine emerging best practices for design and sustainability of peer-led, self-directed courses. A managed care elective course was designed as a student, peer-led course during the 2012-2013 school year at the University of Minnesota College of Pharmacy. As the course evolved, coordinators evaluated the effectiveness and sustainability of a student-led elective. The course required students to select a managed care topic of interest and deliver a discussion-based presentation. Teleconferencing was used to maximize participation and flexibility of pharmacist delegates from local managed care organizations who provided industry insight and expert mentorship. Data sources were gathered via course evaluation surveys, peer evaluations of presentations, and postgraduation surveys. Data were used to guide course improvement, gain insight into motivation for student participation, and evaluate the effect on career choices. During the fall and spring semesters of 2014-2015, 45 students participated and completed surveys: 28 in the fall and 17 in the spring. Seventy percent of enrollees took the course because of interest in managed care; 12% took the course because of referrals from past students; and 12% enrolled to explore topics outside of the pharmacy core curriculum. After completion of the course, 50% of students felt "somewhat comfortable" in discussing managed care topics, and 31% felt "very comfortable." None of the 17 students from the spring semester class answered "not comfortable" or "somewhat not comfortable." Suggestions for improvement from the fall semester class led to smaller class size, a roundtable setting, and new meeting times. In a survey of 6 graduates, 1 student pursued a fellowship; 2 students obtained managed care residencies; and 1 student worked as a managed care pharmacist. Data collected from students enrolled in the managed care elective indicated increased exposure and enhanced knowledge on topics discussed. Data also indicated value and support for the addition of peerled courses to the College of Pharmacy's curriculum. Graduates who took the course have pursued managed care careers and confirmed the benefits of peer-led learning. No outside funding supported this study. The authors have nothing to disclose. Study concept and design were contributed by Tang, Smith, Tse, Tan, and Pittenger. Lau took the lead in data collection, along with Tang and Smith. Data interpretation was performed primarily by Lau, along with Tang, Smith, and Pittenger. The manuscript was written by all the authors and revised primarily by Tang, along with Smith, Lau, Pittenger, and Tan. This research was presented as a poster at the Academy of Managed Care Pharmacy Nexus 2015; October 26-29, 2015; Orlando, Florida.

Shamblen, Stephen R.; Ogilvie, Kristen A.; Collins, David; Saylor, Brian

2013-01-01

This study tests for the efficacy of a school-based drug prevention curriculum (Think Smart) that was designed to reduce use of Harmful Legal Products (HLPs, such as inhalants and over-the-counter drugs), alcohol, tobacco, and other drugs among fifth- and sixth-grade students in frontier Alaska. The curriculum consisted of 12 core sessions and 3 booster sessions administered 2 to 3 months later, and was an adaptation of the Schinke life skills training curriculum for Native Americans. Fourteen communities, which represented a mixture of Caucasian and Alaska Native populations in various regions of the state, were randomly assigned to intervention or control conditions. Single items measuring 30-day substance use and multi-item scales measuring the mediators under study were taken from prior studies. Scales for the mediators demonstrated satisfactory construct validity and internal reliability. A pre-intervention survey was administered in classrooms in each school in the fall semester of the fifth and sixth grades prior to implementing the Think Smart curriculum, and again in the spring semester immediately following the booster session. A follow-up survey was administered 6 months later in the fall semester of the sixth and seventh grades. A multi-level analysis found that the Think Smart curriculum produced a decrease (medium size effect) in the proportion of students who used HLPs over a 30-day period at the 6 month follow-up assessment. There were no effects on other drug use. Further, the direct effect of HLPs use was not mediated by the measured risk and protective factors that have been promoted in the prevention field. Alternative explanations and implications of these results are discussed. PMID:19440837

Kontur, Frederick J.; Terry, Nathan B.

2014-05-01

How do you motivate students to do their homework? Some instructors make students' homework scores a significant percentage of the final course grade. In that case, how much course credit is required? Some instructors do not grade homework at all, instead relying on students' intrinsic motivation to learn the course material. Will this actually work? Some instructors might motivate students by having quiz and/or exam problems closely match the assigned homework problems. In this article, we report on the effectiveness of grade incentives, homework-based quiz problems, and intrinsic motivation for 16 semesters of introductory mechanics and introductory electricity and magnetism (E&M) courses at the United States Air Force Academy (USAFA) between fall 2008 and spring 2012.

Garman, Deanna Essington

The purpose of this quantitative study was to determine if there were significant differences in student success in face-to-face and online biology courses as categorized by gender, major, and age; and as measured by lecture grades, lab grades, and final course grades. The data used for analyses included data from 170 face-to-face sections and 127 online sections from a biology course during the fall and spring semesters beginning fall 2008 through spring 2011. Researchers have reported mixed findings in previous studies juxtaposing online and face-to-face course delivery formats, from no significant differences to differences in grades, learning styles, and satisfaction levels. Four research questions guided this study with data analysis involving t-tests for independent groups and chi-square tests. This researcher noted significant differences in the results of this study: grades, success rates by gender, success rates by health and nonhealth majors, and nontraditional age (≥25) success rate were higher for students in the face-to-face courses; and the attrition rate was higher for students in the online course sections. There was no significant difference found in the success rate for traditional age (<25) students in the face-to-face sections compared to those in the online sections.

Automated seed manipulation and planting

Garcia, Ray; Herrera, Javier; Holcomb, Scott; Kelly, Paul; Myers, Scott; Rosendo, Manny; Sivitz, Herbert; Wolsefer, Dave

1988-01-01

Activities for the Fall Semester, 1987 focused on investigating the mechanical/electrical properties of wheat seeds and forming various Seed Planting System (SPS) concepts based on those properties. The Electrical Division of the design group was formed to devise an SPS using electrostatic charge fields for seeding operations. Experiments concerning seed separation using electrical induction (rearranging of the charges within the seed) were conducted with promising results. The seeds, when exposed to the high voltage and low current field produced by a Van de Graff generator, were observed to move back and forth between two electrodes. An SPS concept has been developed based on this phenomena, and will be developed throughout the Spring Semester, 1988. The Mechanical Division centered on SPS concepts involving valves, pumps, and fluids to separate and deliver seeds. An SPS idea utilizing the pressure difference caused by air as it rushes out of holes drilled in the wall of a closed container has been formulated and will be considered for future development. Also, a system of seed separation and delivery employing a combination of centrifugal force, friction, and air flow was considered.

1992-01-01

The University of Maryland Walking Machine team designed and constructed a robot. This robot was completed in two phases with supervision and suggestions from three professors and one graduate teaching assistant. Bob was designed during the Fall Semester 1991, then machined, assembled, and debugged in the Spring Semester 1992. The project required a total of 4,300 student hours and cost under $8,000. Mechanically, Bob was an exercise in optimization. The robot was designed to test several diverse aspects of robotic potential, including speed, agility, and stability, with simplicity and reliability holding equal importance. For speed and smooth walking motion, the footpath contained a long horizontal component; a vertical aspect was included to allow clearance of obstacles. These challenges were met with a leg design that utilized a unique multi-link mechanism which traveled a modified tear-drop footpath. The electrical requirements included motor, encoder, and voice control circuitry selection, manual controller manufacture, and creation of sensors for guidance. Further, there was also a need for selection of the computer, completion of a preliminary program, and testing of the robot.

Acculturation Gap Distress among Latino Youth: Prospective Links to Family Processes and Youth Depressive Symptoms, Alcohol Use, and Academic Performance.

Latino youth have higher rates of educational and mental health difficulties compared to peers from other racial/ethnic groups. To understand the factors related to such maladjustment, a mediational model linking youth report of parent-youth acculturation gaps to prospective changes (from spring to fall semester) in youth report of academic performance, depressive symptoms and alcohol use via youth report of parent-youth conflict and family cohesion, was studied in a sample of 248 U.S.-and foreign-born Latino youth (Mage = 15.21 years; 50% female; 67% U.S.-born). Parent-youth acculturation gaps were associated with changes in youth academic performance across two semesters via their negative impact on family functioning. For U.S.-born youth, parent-youth acculturation gaps were also linked to changes in alcohol use via parent-adolescent conflict. Results provide some support for the acculturative gap hypotheses while unique findings across nativity groups suggest that such individual-level characteristics may serve as important sources of variation for Latino youth.

Spring break trips as a risk factor for heavy alcohol use among first-year college students.

PubMed

Lee, Christine M; Maggs, Jennifer L; Rankin, Lela A

2006-11-01

Many high school and college students are believed to use spring break vacation to travel to destinations with the intent of engaging in extreme party behaviors, including excessive alcohol use. However, the extent to which spring break travelers' behaviors are more risky than their typical behaviors remains unclear. To assess the impact of spring break as a situational risk factor, we analyzed data collected from 176 first-year college students across 10 weeks using weekly telephone interviews. Using multilevel modeling, we found the following: (1) men, participants in fraternity/sorority organizations, students traveling on spring break trips, and those with higher fun-social alcohol expectancies drank more during the regular semester; (2) alcohol use did not increase during spring break week in general; however, (3) spring break travelers increased their alcohol use during spring break. Spring break trips are a risk factor for escalated alcohol use both during the academic semester and during spring break trips, suggesting that some students may seek out opportunities for excessive alcohol use. Results are discussed in terms of niche selection and prevention implications.

Liu, Dan; El Turkey, Houssein

2017-11-01

In this article, we investigate the implementation of task performance tests in an undergraduate physics laboratory. Two performance tests were carried out over two semesters using the task of building a DC circuit. The first implementation in Spring 2014 had certain concerns such as the privacy of students’ testing and their ‘trial and error’ attempts. These concerns were addressed in Fall 2015 through implementing a second performance test. The second implementation was administered differently but the content of the two tests was the same. We discuss the validity of both implementations and present the correlation (or lack of) between the time that students needed to complete the tests and their grades from a paper-based laboratory assessment method.

My tour in the Engineering Robotics directorate exceeded my expectations. I learned lessons about Creo, manufacturing and assembly, collaboration, and troubleshooting. During my first tour, last spring, I used Creo on a smaller project, but had limited experience with it before starting in the Dynamic Systems Test branch this spring. I gained valuable experience learning assembly design, sheet metal design and designing with intent for manufacturing and assembly. These skills came from working both on the hatch and the floor. I also learned to understand the intent of other designers on models I worked with. While redesigning the floor, I was modifying an existing part and worked to understand what the previous designer had done to make it fit with the new model. Through working with the machine shop and in the mock-up, I learned much more about manufacturing and assembly. I used a Dremel, rivet gun, belt sander, and countersink for the first time. Through taking multiple safety training for different machine shops, I learned new machine shop safety skills specific to each one. This semester also gave me new collaborative opportunities. I collaborated with engineers within my branch as well as with Human Factors and the building 10 machine shop. This experience helped me learn how to design for functionality and assembly, not only for what would be easiest in my designs. In addition to these experiences, I learned many lessons in troubleshooting. I was the first person in my office to use a Windows 10 computer. This caused unexpected issues with NASA services and programs, such as the Digital Data Management Server (DDMS). Because of this, I gained experience finding solutions to lockout and freeze issues as well as Creo specific settings. These will be useful skills to have in the future and will be implemented in future rotations. This co-op tour has motivated me more to finish my degree and pursue my academic goals. I intend to take a machining Career Gateway Elective in the Fall to improve my skills in building as well as designing with manufacturing intent. I am also inspired to take more mechatronics CGE courses before I graduate to learn more about the crossover between mechanical and electrical engineering. This semester, I worked on multiple projects and had the opportunity to learn from engineers of different disciplines. I became proficient in Creo 2.0, a program I had not used significantly before. I finished modifying the hatch for 3D print and made sizeable modifications to the nose floor support design. I also gained hands-on experience that will be useful in my engineering career in the future. I would consider all of these major achievements from this spring semester. Lastly, I learned to ask more questions and to search for the right people to find answers which I know will be a valuable skill in the future. This summer, I will be completing my last rotation in the Flight Operations Directorate at Ellington Air Field. After this last tour, I will be returning to school for the Fall, Spring and Summer. I will graduate in August of 2018. I am looking forward to learning more about the different jobs available to engineers. This division works directly with many different types of aircrafts and I am excited to learn more about this focus of engineering. The Aircraft Operations Division values team work greatly and I intend to improve my interpersonal skills by working with them this summer.

Whitt-Glover, Melicia C; Ham, Sandra A; Yancey, Antronette K

2011-01-01

An increased prevalence of overweight/obesity among children has led to school district level policies to increase physical activity (PA) among elementary school students. Interventions are needed that increase activity levels without sacrificing time spent in academics. We evaluated a policy implementation intervention for to increase in-school PA in elementary schools in Forsyth County, North Carolina, in a randomized study with a delayed intervention control group. The study included third- through fifth-grade classrooms in eight elementary schools. Instant Recess® was used to introduce 10-minute PA breaks in classrooms on schedules determined by teachers. Direct observation was used to measure activity levels, other student behaviors, and teacher behaviors related to PA in the classrooms. Twenty-eight visits to schools were made during the spring and fall semesters of 2009. At baseline 11% to 44% of intervention and control schools were engaged in classroom-based PA. PA increased from baseline to spring follow-up in intervention schools and was maintained the following fall. Control schools decreased PA from baseline to spring and increased PA once they began the intervention. Students in classrooms engaged in Instant Recess exhibited statistically significant increases in light (51%) and moderate-intensity (16%) PA and increases in time spent in on-task behavior (11%). Control schools experienced similar benefits after they began implementing Instant Recess. Instant Recess is useful for increasing PA and improving behavior among elementary school children. Additional research may be needed to understand how to create policies supporting classroom activity breaks and how to assess policy adherence.

Improving performance in thermodynamics: Integrating learning by teaching pedagogy

NASA Astrophysics Data System (ADS)

Campagni, Jamie Anthony

Historically, Thermo is perceived to be the most challenging course in the MET Curriculum at UNC Charlotte. The complexity and difficulties of this course have contributed to the some of the highest DFW rates compared to any other courses offered within the MET program. One hypothesis contributing to high DFW rates is the pedagogy in which Thermo is taught, which is the foundation of this study. Implementation of LBT in the spring 2014 offering of Thermo was deemed a success. The DFW rate in spring 2014 was reduced by 19 percentage points compared to the DFW rate in spring 2013, which exceeded the target of 10 percentage points. However, only cumulative GPA was a significant predictor of whether a student passed or failed the course. The semester in which students took Thermo was not a significant predictor. Students in the spring 2014 semester also exhibited statistically significant higher final exam averages compared to the 2012 and 2013 semesters. In general, students felt that LBT activities enhanced their learning and application of Thermodynamic concepts. Students had a very positive perception of LBT compared to traditional lecture in that 100% of students would recommend this teaching style to other students.

During the fall 2013 semester, I worked at the Kennedy Space Center as an IT Security Intern in support of the Spaceport Command and Control System under the guidance of the IT Security Lead Engineer. Some of my responsibilities included assisting with security plan documentation collection, system hardware and software inventory, and malicious code and malware scanning. Throughout the semester, I had the opportunity to work on a wide range of security related projects. However, there are three projects in particular that stand out. The first project I completed was updating a large interactive spreadsheet that details the SANS Institutes Top 20 Critical Security Controls. My task was to add in all of the new commercial of the shelf (COTS) software listed on the SANS website that can be used to meet their Top 20 controls. In total, there are 153 unique security tools listed by SANS that meet one or more of their 20 controls. My second project was the creation of a database that will allow my mentor to keep track of the work done by the contractors that report to him in a more efficient manner by recording events as they occur throughout the quarter. Lastly, I expanded upon a security assessment of the Linux machines being used on center that I began last semester. To do this, I used a vulnerability and configuration tool that scans hosts remotely through the network and presents the user with an abundance of information detailing each machines configuration. The experience I gained from working on each of these projects has been invaluable, and I look forward to returning in the spring semester to continue working with the IT Security team.

The detailed design of a beam-powered transatmospheric vehicle, the Apollo Lightcraft, was selected as the project for the design course. The principal goal is to reduce the LEO payload delivery cost by at least three orders of magnitude below the Space Shuttle Orbiter in the post 2020 era. The completely reusable, single-stage-to-orbit shuttlecraft will take off and land vertically, and have a reentry heat shield integrated with its lower surface. At appropriate points along the launch trajectory, the combined cycle propulsion system will transition through three or four airbreathing modes, and finally use a pure rocket mode for orbital insertion. The objective for the Spring semester propulsion source was to design and perform a detailed theoretical analysis on an advanced combined-cycle engine suitable for the Apollo Lightcraft. The preliminary theoretical analysis of this combined-cycle engine is now completed, and the acceleration performance along representative orbital trajectories was simulated. The total round trip cost is $3430 or $686 per person. This represents a payload delivery cost of $3.11/lb, which is a factor of 1000 below the STS. The Apollo Lightcraft concept is now ready for a more detailed investigation during the Fall semester Transatmosphere Vehicle Design course.

Collaborative testing is a learning strategy that provides students with the opportunity to learn and practice collaboration. This study aimed to determine the effect of collaborative testing on test performance and retention of course content in nursing students of Shiraz University of Medical Sciences, Shiraz, Iran. This quasi-experimental study was carried out on 84 students enrolled in the course of Medical-Surgical 2 in Spring 2013 and Fall 2013 semesters. The control group consisting of 39 students participated in the first mid-term exam in an individual format. The intervention group, on the other hand, consisted of 45 students who took the test in a two-stage process. The first stage included an individual testing, while the second stage was a collaborative one given in groups of five individuals chosen randomly. Four weeks later, in order to investigate retention of the course content, both groups took part in the second mid-term exam held individually. The study findings showed significant difference between the mean scores in the intervention group in the Fall 2013 semester (p=0.001). Besides, a statistically significant difference was found between the two groups regarding the tests mean scores (p=0.001). Moreover, retention of course content improved in the collaborative group (p=0.001). The results indicated an increase in test performance and a long-term learning enhancement in collaborative testing compared with the traditional method. Collaborative testing, as an active learning technique and a valuable assessment method, can help nursing instructors provide the alumni with strong problem-solving and critical thinking abilities at healthcare environments.

Restructuring the CS 1 classroom: Examining the effect of open laboratory-based classes vs. closed laboratory-based classes on Computer Science 1 students' achievement and attitudes toward computers and computer courses

NASA Astrophysics Data System (ADS)

Henderson, Jean Foster

The purpose of this study was to assess the effect of classroom restructuring involving computer laboratories on student achievement and student attitudes toward computers and computer courses. The effects of the targeted student attributes of gender, previous programming experience, math background, and learning style were also examined. The open lab-based class structure consisted of a traditional lecture class with a separate, unscheduled lab component in which lab assignments were completed outside of class; the closed lab-based class structure integrated a lab component within the lecture class so that half the class was reserved for lecture and half the class was reserved for students to complete lab assignments by working cooperatively with each other and under the supervision and guidance of the instructor. The sample consisted of 71 students enrolled in four intact classes of Computer Science I during the fall and spring semesters of the 2006--2007 school year at two southern universities: two classes were held in the fall (one at each university) and two classes were held in the spring (one at each university). A counterbalanced repeated measures design was used in which all students experienced both class structures for half of each semester. The order of control and treatment was rotated among the four classes. All students received the same amount of class and instructor time. A multivariate analysis of variance (MANOVA) via a multiple regression strategy was used to test the study's hypotheses. Although the overall MANOVA model was statistically significant, independent follow-up univariate analyses relative to each dependent measure found that the only significant research factor was math background: Students whose mathematics background was at the level of Calculus I or higher had significantly higher student achievement than students whose mathematics background was less than Calculus I. The results suggest that classroom structures that incorporate an open laboratory setting are just as effective on student achievement and attitudes as classroom structures that incorporate a closed laboratory setting. The results also suggest that math background is a strong predictor of student achievement in CS 1.

2007-12-01

We are completing a cooperative astronomy education project designed to improve undergraduate laboratories at RPI (a PhD granting institution) and Siena College (a nearby liberal arts college). Following the overhaul of a 40-year-old, 16" B&C telescope on the RPI campus, we have made it available for use for hundreds of students at both schools and once per week to the public. This telescope has been integrated into studio-style, hands-on, inquiry-based laboratories designed to challenge student misconceptions. An assessment test was designed and distributed to the students taking the course at the beginning and end of the Fall 2007 semester, the results of which we compare to a baseline study undertaken in Fall 2006 and Spring 2007 to determine the efficacy of the laboratories in improving undergraduate astronomy education. In order to handle a large number of students using the main telescope and a limited number of smaller telescopes, we have cycled students through concurrent activites. This has been enabled by the rapid acquisition and imaging of targets made possible by the upgrade to the control system of our 16" telescope. We show preliminary results of the Fall 2007 assessments and comparisons to the baseline assessment. This project is funded by an NSF CCLI grant, 05-11340.

College Student Affect and Heavy Drinking: Variable Associations Across Days, Semesters, and People

PubMed Central

Howard, Andrea L.; Patrick, Megan E.; Maggs, Jennifer L.

2014-01-01

This study tested associations between positive and negative affect and heavy drinking in 734 college students who completed daily diaries in 14-day bursts once per semester over 7 semesters (≤98 days per person). Three-level multilevel models tested whether affect and heavy drinking were linked across days, semesters, and persons. Higher daily, between-semester, and between-person positive affect were each associated with a greater odds of heavy drinking on weekdays and on weekend days. A significant interaction with semester in college showed that the association between daily positive affect and heavy drinking on weekend days became stronger over time. That is, heavy drinking on a weekend day with higher positive affect was more likely in later years of college (OR=2.93, Fall of 4th year), compared to earlier in college (OR=1.80, Fall of 1st year). A similar interaction was found for between-semester positive affect and heavy drinking on weekdays. Higher daily negative affect was associated with a greater odds of heavy drinking on weekdays only for students who first began drinking in 7th grade or earlier (OR=2.36). Results of this study highlight the importance of varied time spans in studying the etiology, consequences, and prevention of heavy drinking. Harm-reduction strategies that target positive affect-related drinking by encouraging protective behaviors during celebratory events may become increasingly important as students transition to later years of college.

OBJECTIVES: This study evaluated the long-term effectiveness of Safer Choices, a theory-based, multi-component educational program designed to reduce sexual risk behaviors and increase protective behaviors in preventing HIV, other STDs, and pregnancy among high school students. METHODS: The study used a randomized controlled trial involving 20 high schools in California and Texas. A cohort of 3869 ninth-grade students was tracked for 31 months from fall semester 1993 (baseline) to spring semester 1996 (31-month follow-up). Data were collected using self-report surveys administered by trained data collectors. Response rate at 31-month follow-up was 79%. RESULTS: Safer Choices had its greatest effect on measures involving condom use. The program reduced the frequency of intercourse without a condom during the three months prior to the survey, reduced the number of sexual partners with whom students had intercourse without a condom, and increased use of condoms and other protection against pregnancy at last intercourse. Safer Choices also improved 7 of 13 psychosocial variables, many related to condom use, but did not have a significant effect upon rates of sexual initiation. CONCLUSIONS: The Safer Choices program was effective in reducing important risk behaviors for HIV, other STDs, and pregnancy and in enhancing most psychosocial determinants of such behavior.

Chronicling a successful secondary implementation of Studio Physics

NASA Astrophysics Data System (ADS)

Kohl, Patrick B.; Vincent Kuo, H.

2012-09-01

The Colorado School of Mines (CSM) has taught its first-semester calculus-based introductory physics course (Physics I) using a hybrid lecture/Studio Physics format since the spring of 1997. Starting in the fall of 2007, we have been converting the second semester of our calculus-based introductory physics course (Physics II) to a hybrid lecture/Studio Physics format, beginning from a traditional lecture/lab/recitation course. In this paper, we document the stages of this transformation, highlighting what has worked and what has not, and the challenges and benefits associated with the switch to Studio Physics. A major goal in this study is to develop a method for secondary implementations of Studio physics that keeps the time and resource investments manageable. We describe the history of Studio at CSM and characterize our progress via several metrics, including pre/post Conceptual Survey of Electricity and Magnetism (CSEM) scores, Colorado Learning About Science Survey scores (CLASS), exam scores, failure rates, and a variety of qualitative observations. Results suggest that Studio has increased student performance and satisfaction despite an aggressive expansion of class sizes in the past few years. Gains have been concentrated mostly in problem-solving skills and exam performance (as opposed to conceptual survey gains), in contrast to what has sometimes been seen in other studies.

Natural Mentoring Relationships and the Adjustment to College among Underrepresented Students.

This study investigated associations between natural mentoring relationships and academic performance via psychological distress among underrepresented college students attending an elite predominantly White institution (PWI). Specifically, this study explored whether the quantity of natural mentors possessed upon college entry, the retention of natural mentors across the first year of college, and overall changes in the number of natural mentors possessed during the first year of college predicted improvements in students' semester grade point averages (GPAs) via reductions in psychological distress. Participants in this study included 336 first-year undergraduate students attending a selective PWI. Students were eligible to participate in this study if they were first-generation college students, students from economically disadvantaged backgrounds, or students from underrepresented racial/ethnic minority groups. Results of this study indicated that a greater number of retained natural mentoring relationships across the first year of college were associated with improvements in students' GPAs via reductions in symptoms of depression from the Fall to Spring semester. The results of this study suggest that institutional efforts to support the maintenance of preexisting mentoring relationships may be an effective approach to promoting the academic success of underrepresented college students during the first year of college. © Society for Community Research and Action 2016.

The Development of the Planet Formation Concept Inventory: A Preliminary Analysis of Version 1

NASA Astrophysics Data System (ADS)

Simon, Molly; Impey, Chris David; Buxner, Sanlyn

2018-01-01

The topic of planet formation is poorly represented in the educational literature, especially at the college level. As recently as 2014, when developing the Test of Astronomy Standards (TOAST), Slater (2014) noted that for two topics (formation of the Solar System and cosmology), “high quality test items that reflect our current understanding of students’ conceptions were not available [in the literature]” (Slater,2014, p. 8). Furthermore, nearly half of ASTR 101 enrollments are at 2 year/community colleges where both instructors and students have little access to current research and models of planet formation. In response, we administered six student replied response (SSR) short answer questions on the topic of planet formation to n = 1,050 students enrolled in introductory astronomy and planetary science courses at The University of Arizona in the Fall 2016 and Spring 2017 semesters. After analyzing and coding the data from the SSR questions, we developed a preliminary version of the Planet Formation Concept Inventory (PFCI). The PFCI is a multiple-choice instrument with 20 planet formation-related questions, and 4 demographic-related questions. We administered version 1 of the PFCI to six introductory astronomy and planetary science courses (n ~ 700 students) during the Fall 2017 semester. We provided students with 7-8 multiple-choice with explanation of reasoning (MCER) questions from the PFCI. Students selected an answer (similar to a traditional multiple-choice test), and then briefly explained why they chose the answer they did. We also conducted interviews with ~15 students to receive feedback on the quality of the questions and clarity of the instrument. We will present an analysis of the MCER responses and student interviews, and discuss any modifications that will be made to the instrument as a result.

To analyze absentees due to injury among primary school pupils in Hubei, 2012-2013; and to provide theoretical basis for the prevention and control of injuries. A total of 32 primary schools in Qianjiang city and Shayang county were sampled to conduct injury absenteeism surveillance, and the total number of students was 21 493. The surveillance contents included absent dates, genders, grades, initial or return absent, and the detailed absent reasons. The classification of injury was based on the 10th Revision of the international classification of diseases developed by WHO. Data from 2012-2013 school-year were extracted from the surveillance system for analysis. The total surveillance period was 182 days, of which the fall semester was 98 days and the spring semester was 84 days. The absenteeism rate and injury rate in different characteristics of primary school students were compared by χ² test, and the possible risk factors of injury were preliminary explored by calculating the RR (95% CI) value. The total daily injury absenteeism rate was 8.26/100 100 during 2012-2013 school-year in 32 primary schools in Hubei province, which was higher in fall semester (9.16/100 000), Qianjiang area (9.63/100 000), rural primary schools (13.44/100 000), boys (9.57/100 000), 1-2 grades (10.41/100 000), and the differences were significant (P < 0.05). The total injury rate was 0.46%. Rural primary schools (RR = 2.32, 95% CI: 1.46-3.70), boys (RR = 1.88, 95% CI: 1.23-2.87), and 3-4 grades (RR = 1.85, 95% CI: 1.10-3.09) were identified as high-risk factors, while using city primary schools, girls, and 5-6 grades as references, respectively. The injury absenteeism rate and injury rate were more higher in rural primary schools, boys and low or middle grades in Hubei province during 2012 to 2013 school year, so monitoring and preventive measures should be focused on those students.

Weight Gain Reduction Among 2-Year College Students: The CHOICES RCT

Introduction The young adult years have been recognized as an influential period for excess weight gain. Non-traditional students and those attending 2-year community colleges are at particularly high risk for a range of adverse weight-related outcomes. Design Choosing Healthy Options in College Environments and Settings was an RCT with students randomly assigned into a control or intervention condition after baseline assessment. The study was designed to evaluate if a 24-month weight gain prevention intervention reduces the expected increase in BMI and overweight prevalence in young adults attending 2-year colleges. Two cohorts were recruited, corresponding to the fall and spring semesters. Data collection occurred at four time points for each cohort, with baseline occurring in fall 2011 for Cohort 1 and spring 2012 for Cohort 2. The 24-month follow-up occurred in fall 2013 for Cohort 1 and spring 2014 for Cohort 2. Data analysis occurred in 2015–2016. Setting/participants This research was conducted with 441 students from three community colleges in Minnesota. Intervention The 24-month intervention began with a 1-credit college course on healthy weight behaviors. A social networking and social support website was introduced as part of the course and participation encouraged for the duration of the trial. Main outcome measures Changes in BMI, weight, body fat percentage, waist circumference, and weight status were assessed. Results Retention of the cohorts at 24 months was 83.4%. There was not a statistically significant difference in BMI between conditions at the end of the trial. However, there was a statically significant difference in the prevalence of overweight/obesity between treatment conditions at 24 months. Also, participants randomized to the intervention who were overweight or obese at baseline were more than three times as likely to transition to a healthy weight by the end of the trial as compared with control students. Conclusions The intervention was not successful in achieving BMI differences between treatment groups. However, an 8% reduction in the prevalence of overweight and obesity over time may have population-level significance. PMID:27939237

Berman, Elizabeth R; Johnson, Rachel K

2015-07-01

We investigated how the removal of bottled water along with a minimum healthy beverage requirement affected the purchasing behavior, healthiness of beverage choices, and consumption of calories and added sugars of university campus consumers. With shipment data as a proxy, we estimated bottled beverage consumption over 3 consecutive semesters: baseline (spring 2012), when a 30% healthy beverage ratio was enacted (fall 2012), and when bottled water was removed (spring 2013) at the University of Vermont. We assessed changes in number and type of beverages and per capita calories, total sugars, and added sugars shipped. Per capita shipments of bottles, calories, sugars, and added sugars increased significantly when bottled water was removed. Shipments of healthy beverages declined significantly, whereas shipments of less healthy beverages increased significantly. As bottled water sales dropped to zero, sales of sugar-free beverages and sugar-sweetened beverages increased. The bottled water ban did not reduce the number of bottles entering the waste stream from the university campus, the ultimate goal of the ban. With the removal of bottled water, consumers increased their consumption of less healthy bottled beverages.

We assessed changes in number and type of beverages and per capita calories, total sugars, and added sugars shipped. Results. Per capita shipments of bottles, calories, sugars, and added sugars increased significantly when bottled water was removed. Shipments of healthy beverages declined significantly, whereas shipments of less healthy beverages increased significantly. As bottled water sales dropped to zero, sales of sugar-free beverages and sugar-sweetened beverages increased. Conclusions. The bottled water ban did not reduce the number of bottles entering the waste stream from the university campus, the ultimate goal of the ban.

The timing and magnitude of phytoplankton blooms in subarctic ecosystems often strongly influence the amount of energy that is transferred through subsequent trophic pathways. In the eastern Bering Sea, spring bloom timing has been linked to ice retreat timing and production of zooplankton and fish. A large part of the eastern Bering Sea shelf (~500 km wide) is ice-covered during winter and spring. Four oceanographic moorings have been deployed along the 70-m depth contour of the eastern Bering Sea shelf with the southern location occupied annually since 1995, the two northern locations since 2004 and the remaining location since 2001. Chlorophyll a fluorescence data from the four moorings provide 37 realizations of a spring bloom and 33 realizations of a fall bloom. We found that in the eastern Bering Sea: if ice was present after mid-March, spring bloom timing was related to ice retreat timing (p<0.001, df=1, 24); if ice was absent or retreated before mid-March, a spring bloom usually occurred in May or early June (average day 148, SE=3.5, n=11). A fall bloom also commonly occurred, usually in late September (average day 274, SE=4.2, n=33), and its timing was not significantly related to the timing of storms (p=0.88, df=1, 27) or fall water column overturn (p=0.49, df=1, 27). The magnitudes of the spring and fall blooms were correlated (p=0.011, df=28). The interval between the spring and fall blooms varied between four to six months depending on year and location. We present a hypothesis to explain how the large crustacean zooplankton taxa Calanus spp. likely respond to variation in the interval between blooms (spring to fall and fall to spring).

The Use of “Non-Fiction Novels” in a Sensation and Perception Course

Scientific material can be difficult to relate to everyday knowledge. Textbook facts can be abstract. This Study of Teaching and Learning project examined the use of “non-fiction novels” (biographies and other books that read like novels but are true) in an undergraduate Sensation and Perception course in order to increase the concreteness of the reading material and to give the students a story on which to hang the facts learned in lecture. In Phase I (Fall 2009) non-fiction novels were used for half of the units and a standard textbook for the other half. In Phase II (Fall 2010) only non-fiction novels were used. The Fall 2009 class was very positive about the use of non-fiction novels, but exam scores did not mirror this enthusiasm, either on semester exam scores or on a four-month re-take of the cumulative final exam. In contrast, the Fall 2010 class missed having a textbook, but exam performance significantly improved over prior semesters, and performance on the four-month re-take of the cumulative final exam showed performance equivalent to the Fall 2009 class’s four-month performance on questions from textbook units. In both semesters, the effectiveness of the instructor in stimulating student interest was significantly higher than in prior years where only the textbook was used. In addition, 68% of the students said that reading the non-fiction novels made them want to learn more about our sensory systems. PMID:23626489

1987-01-01

A group of fifteen students in the Electrical Engineering Department at the University of Maryland, College Park, has been involved in a design project under the sponsorship of NASA Headquarters, NASA Goddard Space Flight Center and the Systems Research Center (SRC) at UMCP. The goal of the NASA/USRA project was to first obtain a refinement of the design work done in Spring 1986 on the proposed Mobile Remote Manipulator System (MRMS) for the Space Station. This was followed by design exercises involving the OMV and two armed service vehicle. Three students worked on projects suggested by NASA Goddard scientists for ten weeks this past summer. The knowledge gained from the summer design exercise has been used to improve our current design of the MRMS. To this end, the following program was undertaken for the Fall semester 1986: (1) refinement of the MRMS design; and (2) addition of vision capability to our design.

Playing with Others: Head Start Children's Peer Play and Relations with Kindergarten School Competence

2014-01-01

Time-sampled observations of Head Start preschoolers' (N = 264; 51.5% boys; 76% Mexican American; M = 53.11 and SD = 6.15 months of age) peer play in the classroom were gathered during fall and spring semesters. One year later, kindergarten teachers rated these children's school competence. Latent growth models indicated that, on average, children's peer play was moderately frequent and increased over time during preschool. Children with higher initial levels or with higher slopes of peer play in Head Start had higher levels of kindergarten school competence. Results suggest that Head Start children's engagement with peers may foster development of skills that help their transition into formal schooling. These findings highlight the importance of peer play, and suggest that peer play in Head Start classrooms contributes to children's adaptation to the demands of formal schooling. PMID:24882941

Lower Nitrous Oxide Emissions from Anhydrous Ammonia Application Prior to Soil Freezing in Late Fall Than Spring Pre-Plant Application.

Tenuta, Mario; Gao, Xiaopeng; Flaten, Donald N; Amiro, Brian D

2016-07-01

Fall application of anhydrous ammonia in Manitoba is common but its impact on nitrous oxide (NO) emissions is not well known. A 2-yr study compared application before freeze-up in late fall to spring pre-plant application of anhydrous ammonia on nitrous oxide (NO) emissions from a clay soil in the Red River Valley, Manitoba. Spring wheat ( L.) and corn ( L.) were grown on two 4-ha fields in 2011 and 2012, respectively. Field-scale flux of NO was measured using a flux-gradient micrometeorological approach. Late fall treatment did not induce NO emissions soon after application or in winter likely because soil was frozen. Application time did alter the temporal pattern of emissions with late fall and spring pre-plant applications significantly increasing median daily NO flux at spring thaw and early crop growing season, respectively. The majority of emissions occurred in early growing season resulting in cumulative emissions for the crop year being numerically 33% less for late fall than spring pre-plant application. Poor yield in the first year with late fall treatment occurred because of weed and volunteer growth with delayed planting. Results show late fall application of anhydrous ammonia before freeze-up increased NO emissions at thaw and decreased emissions for the early growing season compared to spring pre-plant application. However, improved nitrogen availability of late fall application to crops the following year is required when planting is delayed because of excessive moisture in spring.

Assessment of a novel group-centered testing schema in an upper-level undergraduate molecular biotechnology course.

2013-01-01

Providing students with assignments that focus on critical thinking is an important part of their scientific and intellectual development. However, as class sizes increase, so does the grading burden, prohibiting many faculty from incorporating critical thinking assignments in the classroom. In an effort to continue to provide our students with meaningful critical thinking exercises, we implemented a novel group-centered, problem-based testing scheme. We wanted to assess how performing critical thinking problem sets as group work compares to performing the sets as individual work, in terms of student attitudes and learning outcomes. During two semesters of our recombinant DNA course, students had the same lecture material and similar assessments. In the Fall semester, student learning was assessed by two collaborative take-home exams, followed immediately by individual, closed-book in-class exams on the same content, as well as a final cumulative exam. Student teams on the take-home exams were instructor-assigned, and each team turned in one collaborative exam. In the Spring semester, the control group of students were required to turn in their own individual take-home exams, followed by the in-class exams and final cumulative exam. For the majority of students, learning outcomes were met, regardless of whether they worked in teams. In addition, collaborative learning was favorably received by students and grading was reduced for instructors. These data suggest that group-centered, problem-based learning is a useful model for achievement of student learning outcomes in courses where it would be infeasible to provide feedback on individual critical thinking assignments due to grading volume.

While the underrepresentation of women in the fast-growing STEM field of computer science (CS) has been much studied, no consensus exists on the key factors influencing this widening gender gap. Possible suspects include gender differences in aptitude, interest, and academic environment. Our study contributes to this literature by applying student engagement research to study the experiences of college students studying CS, to assess the degree to which differences in men and women's engagement may help account for gender inequity in the field. Specifically, we use the Experience Sampling Method (ESM) to evaluate in real-time the engagement of college students during varied activities and environments. Over the course of a full week in fall semester and a full week in spring semester, 165 students majoring in CS at two Research I universities were "beeped" several times a day via a smartphone app prompting them to fill out a short questionnaire including open-ended and scaled items. These responses were paired with administrative and over 2 years of transcript data provided by their institutions. We used mean comparisons and logistic regression analysis to compare enrollment and persistence patterns among CS men and women. Results suggest that despite the obstacles associated with women's underrepresentation in computer science, women are more likely to continue taking computer science courses when they felt challenged and skilled in their initial computer science classes. We discuss implications for further research.

Enabling students to learn: Design, implementation and assessment of a supplemental study strategies course for an introductory undergraduate biology course

NASA Astrophysics Data System (ADS)

Sriram, Jayanthi Sanjeevi

Attrition in the STEM disciplines is a national problem and one of the important reasons for this is student experiences in introductory courses. A myriad of factors influence students' experiences in those courses; inadequate student preparation is one of the most cited reasons. Incoming freshmen often lack the learning strategies required to meaningfully learn and succeed in college courses. Unfortunately, the instructors have limited time and/or have little experience in teaching learning strategies. In this paper, the design, implementation, and evaluation of a Supplemental Course (SC) model that emphasizes learning strategies is presented. SC was offered concurrently with the introductory biology courses for four consecutive semesters (fall 2011 to spring 2013); for 10 weeks in fall 2012 and 7 weeks in the other semesters at Miami University. 10 weeks SC began earlier in the semester than the shorter SC. This study evaluated the effects of the SC on students' (1) performance in the introductory biology course, (2) perceived changes in self-regulation and social support, and (3) experiences in the introductory biology course before, during, and after participation in the SC. A mixed methods approach was used to address these goals. A pre-post survey was administered to obtain students' use of self-regulation strategies and social-support data. Quantitative methods were utilized to analyze content exam grades and changes in self-regulation strategies and social-support. To explore the experiences of the students, semi-structured interviews were conducted, followed by analysis using grounded theory. The findings reveal that participants of the longer duration SC (with an earlier start date) significantly improved in content exam performance, perceived use of self-regulation strategies, and social support compared to the non-participants. Participants of the shorter duration SC (with a later start date) did not significantly improve in content exam performance compared to the non-participants, however, demonstrated lower failure and withdrawal rates in content course than the non-participants. Qualitative findings provided further support for changes in students' study habits after participation in the SC. Literature suggests the need for early intervention, which is a critical determinant of student success. Findings presented here support that need and suggest a model that can be implemented in a discipline specific manner, perhaps with modifications.

Sea otter (Enhydra lutris) abundance and distribution in the Gulf of Alaska west of Prince William Sound were surveyed by helicopter in the spring of 1989 at the time of the Exxon Valdez oil spill and the following fall. Estimated population sizes did not significantly decline between spring and fall for areas with comparable survey data. No significant (p>0.05) shifts of sea otter distributions in heavily, lightly and unoiled areas were detected between spring and fall surveys.

Rose, T

I'm writing at the request of the Pit River Tribe to offer my professional opinion as a geochemist regarding the origin of groundwater discharge at the Fall River Springs, Shasta Co., California. In 1997, I conducted a study of the large volume cold springs associated with the Cascade Volcanoes in northern California, in collaboration with one of my colleagues. This work was published as a Lawrence Livermore National Laboratory report (Davisson and Rose, 1997). The Fall River Springs emerge from the distal end of the Giant Crater Lava Field, a laterally extensive basalt flow that stretches from the southern flankmore » of Medicine Lake Volcano southward for a distance of 40 km. Both Medicine Lake Volcano and the Giant Crater Lava Field have virtually no surface water drainages. Precipitation that falls in these areas is inferred to seep into fractures in the rock, where it is carried down gradient under the force of gravity. Mean annual precipitation rates on Medicine Lake Volcano and the Giant Crater Lava field are adequate to account for the {approx}1200 ft{sup 3}/sec discharge of the Fall River Springs. To evaluate the origin of the springs using geochemical methods, water samples were collected from the Fall River Springs and the Medicine Lake highlands and analyzed for oxygen and hydrogen isotope ratios. The isotope ratios measured for a groundwater sample are diagnostic of the average composition of the precipitation from which the water was derived. The isotope ratios of rain and snow also vary systematically with elevation, such that groundwater derived from recharge at higher elevations can be distinguished from that which originated at lower elevations. The stable isotope data for the Fall River Springs are consistent with groundwater recharge on the Medicine Lake Volcano and adjacent lava field. Mass balance calculations suggest that approximately half of the Fall River Springs flow is derived from the volcanic edifice. Rose and Davisson (1996) showed that the large volume cold springs associated with the Cascade Volcanoes commonly contain dissolved CO{sub 2} that originated from the volcanoes. This volcanic CO{sub 2} component is readily identified from carbon-14 measurements of the water. Carbon-14 analyses of the Fall River samples indicate that at least 27% of the dissolved inorganic carbon in the springs was derived from a volcanic CO{sub 2} source. Such a large volcanic CO{sub 2} flux requires that the groundwater supplying flow to the Fall River Springs must originate from a volcano where magma degassing is actively occurring. Given the hydrogeologic configuration of the Fall River aquifer system, it appears that the Medicine Lake Volcano is the only likely source of the volcanic CO{sub 2}. These data independently confirm the Medicine Lake highlands as a significant recharge source for the Fall River Springs. Moreover, these data indicate that groundwater recharge occurring on Medicine Lake Volcano must interact with a CO{sub 2} volatile phase derived from the geothermal system beneath the volcano. The lack of hot springs on Medicine Lake Volcano suggests that the geothermal system underlying the volcano is relatively tightly sealed. Nevertheless, it is probable that the geothermal fluid originates from precipitation falling on the volcanic edifice. This is the same water that supplies an important fraction of the Fall River Spring discharge. The source of the geothermal fluid can be evaluated using stable isotopes. The oxygen isotope signature of the geothermal fluid may have been modified by high temperature oxygen isotope exchange with the surrounding rock, but the hydrogen isotope signature should still be diagnostic of the origin of the fluid. Although the geothermal system appears to be largely decoupled from the shallow groundwater system that supplies the Fall River Springs, it is uncertain what impact the development of the geothermal system as an energy resource would have on groundwater circulation patterns on the volcano. Given the importance of the Fall River Springs as a water resource for the State of California, it would be prudent to carefully evaluate this question before proceeding with geothermal energy development on Medicine Lake Volcano.« less

Developing an Undergraduate Astronomical Research Program

NASA Astrophysics Data System (ADS)

Genet, R. M.

2007-05-01

Time-series astronomical photometry is an area of scientific research well suited to amateurs and undergraduates, and their backyard and campus observatories. I describe two past one-semester community college research programs, one six year ago and one last fall (2006), as well as a program planned for this coming fall (2007). The 2001 program, a course at Central Arizona College, utilized a robotic telescope at the Fairborn Observatory. Results were presented at the 200th meeting of the American Astronomical Society. This past fall, three students, in a 17-week, one-semester course at Cuesta College, were able to plan a research program, make several thousand CCD photometric observations, reduce and analyze their data, write up their results and, on the last day of class, send their paper off to a refereed journal, the JAAVSO. A course is being offered this coming fall (2007) that will involve about a dozen students (including high school students), several local amateur astronomers, and at least three CCD- equipped semi-automatic telescopes. Potential solutions to "scaling up" challenges created by increased class size are discussed.

Nitrogen (N) management strategies that maintain high crop productivity with reduced water quality impacts are needed for tile-drained landscapes of the US Midwest. The objectives of this study were to determine the effect of N application rate, timing, and fall nitrapyrin addition on tile drainage nitrate losses, corn ( L.) yield, N recovery efficiency, and postharvest soil nitrate content over 3 yr in a corn-soybean [ (L.) Merr.] rotation. In addition to an unfertilized control, the following eight N treatments were applied as anhydrous ammonia in a replicated, field-scale experiment with both corn and soybean phases present each year in Illinois: fall and spring applications of 78, 156, and 234 kg N ha, fall application of 156 kg N ha + nitrapyrin, and sidedress (V5-V6) application of 156 kg N ha. Across the 3-yr study period, increases in flow-weighted NO concentrations were found with increasing N rate for fall and spring N applications, whereas N load results were variable. At the same N rate, spring vs. fall N applications reduced flow-weighted NO concentrations only in the corn-soybean-corn rotation. Fall nitrapyrin and sidedress N treatments did not decrease flo8w-weighted NO concentrations in either rotation compared with fall and spring N applications, respectively, or increase corn yield, crop N uptake, or N recovery efficiency in any year. This study indicates that compared with fall N application, spring and sidedress N applications (for corn-soybean-corn) and sidedress N applications (for soybean-corn-soybean) reduced 3-yr mean flow-weighted NO concentrations while maintaining yields.

Increasing Impact of Coursework Through Deep Analytics

2014-12-01

Over the past few years, ASU has developed the online astrobiology lab course Habitable Worlds, which has been offered to over 1,500 students over seven semesters. The course is offered through Smart Sparrow's intelligent tutoring system, which records student answers, time on question, simulation setups, and additional data that we refer to as "analytics". As the development of the course has stabilized, we have been able to devote more time to analyzing these data, extracting patterns of student behavior and how they have changed as the course has developed. During the most recent two semesters, pre- and post-tests of content knowledge related to the greenhouse effect were administered to assess changes in students' knowledge. The results of the Fall 2013 content assessment and an analysis of each step of every activity using the course platform analytics were used to identify problematic concepts and lesson elements, which were redesigned for the following semester. We observed a statistically significant improvement from pre to post instruction in Spring 2014. Preliminary results seem to indicate that several interactive activities, which replaced written/spoken content, contributed to this positive outcome. Our study demonstrates the benefit of deep analytics for thorough analysis of student results and quick iteration, allowing for significantly improved exercises to be redeployed quickly. The misconceptions that students have and retain depend on the individual student, although certain patterns do emerge in the class as a whole. These patterns can be seen in student discussion board behavior, the types of answers they submit, and the patterns of mistakes they make. By interrogating this wealth of data, we seek to identify the patterns that outstanding, struggling, and failing students display and how early in the class these patterns can be detected. If these patterns can be identified and detected early in the semester, instructors can intervene earlier, prodding unmotivated students while devoting significant attention to students who struggle yet remain interested in the subject matter. This offers a marked improvement over the more common practice of waiting (often futilely) for students to seek help.

Hearth, Donald P.

1990-01-01

The purpose of this overview is to summarize the objectives and structure of the Center. The center is a major element of the University's initiative to upgrade space-related research and education on the Boulder campus. With the support of NASA's University Space Engineering Research Centers Program, we provide a mechanism for interdisciplinary and system-level space engineering research and training. Twenty faculty members and 56 students from seven academic units are associated with the Center and are interacting with each other and with the CSC Associates. As a result of feedback from the 1989 symposium, we have focused the efforts of the Center during the past several months on Lunar Base construction. This included a system level study of a Lunar Base in an Independent Study Project by a group of students from across the Center during the spring semester. This project is being continued this fall. During the two-year history of the Center, 13 students previously affiliated with the Center have graduated and there have been 55 publications from the Center.

Drivers of disparity: differences in socially based risk factors of self-injurious and suicidal behaviors among sexual minority college students.

2012-01-01

Lesbian, gay, and bisexual (ie, sexual minority) populations have increased prevalence of both self-injurious and suicidal behaviors, but reasons for these disparities are poorly understood. To test the association between socially based stressors (eg, victimization, discrimination) and self-injurious behavior, suicide ideation, and suicide attempt. A national sample of college-attending 18- to 24-year-olds. Random or census samples from postsecondary educational institutions that administered the National College Health Assessment during the Fall 2008 and Spring 2009 semesters. Sexual minorities reported more socially based stressors than heterosexuals. Bisexuals exhibited greatest prevalence of self-injurious and suicidal behaviors. In adjusted models, intimate partner violence was most consistently associated with self-injurious behaviors. Sexual minorities' elevated risks of self-injurious and suicidal behaviors may stem from higher exposure to socially based stressors. Within-group differences among sexual minorities offer insight to specific risk factors that may contribute to elevated self-injurious and suicidal behaviors in sexual minority populations.

(3122) Florence is an asteroid that made the headlines with its close approach to Earth in late 2017. It is one of the biggest and brightest near-Earth asteroids that has been discovered and it has recently been found to have two moons. By observing the light reflected off an asteroid, we can measure its brightness over time and determine the rotational period of the asteroid. An asteroid’s rotational period can reveal information about its physical characteristics, such as its shape, and further our knowledge about processes that contribute to asteroid rotation in general. The Harvard Observing Project (HOP) is an initiative that allows undergraduates to learn about observational astronomy and take part in formal data collection and analysis. Over the course of the fall 2017 semester, HOP obtained four multi-hour, continuous observations in the R-band of the asteroid using the Harvard University 16-inch Clay Telescope. In our analysis, we reduced the images and performed astrometry and photometry on the data. The asteroid’s light curve was produced using AstroImageJ and we used the Python package gatspy to determine its rotational period. We found the rotational period to be 2.22 hours +/- 0.25, which agrees with the known rotational period of 2.3580 hours +/- 0.0002. This spring 2018 semester we are applying our methods to data collected on asteroids with unknown rotational periods and plan to present our findings.

Engagement, Persistence, and Gender in Computer Science: Results of a Smartphone ESM Study

While the underrepresentation of women in the fast-growing STEM field of computer science (CS) has been much studied, no consensus exists on the key factors influencing this widening gender gap. Possible suspects include gender differences in aptitude, interest, and academic environment. Our study contributes to this literature by applying student engagement research to study the experiences of college students studying CS, to assess the degree to which differences in men and women's engagement may help account for gender inequity in the field. Specifically, we use the Experience Sampling Method (ESM) to evaluate in real-time the engagement of college students during varied activities and environments. Over the course of a full week in fall semester and a full week in spring semester, 165 students majoring in CS at two Research I universities were “beeped” several times a day via a smartphone app prompting them to fill out a short questionnaire including open-ended and scaled items. These responses were paired with administrative and over 2 years of transcript data provided by their institutions. We used mean comparisons and logistic regression analysis to compare enrollment and persistence patterns among CS men and women. Results suggest that despite the obstacles associated with women's underrepresentation in computer science, women are more likely to continue taking computer science courses when they felt challenged and skilled in their initial computer science classes. We discuss implications for further research. PMID:28487664

Our public outreach group Dark Skies, Bright Kids! (DSBK) fosters science literacy in Virginia by bringing a hands-on approach to astronomy that engages children's natural excitement and curiosity. We are an entirely volunteer-run group based out of the Department of Astronomy at the University of Virginia and we enthusiastically utilize astronomy as a 'gateway science.' We create long-term relationships with students during an 8 to 10 week long, after-school astronomy club at under served elementary schools in neighboring counties, and we visited 3 different schools in 2013. Additionally, we organize and participate in science events throughout the community. The fifth year of DSBK was marked by surpassing 10,000 contact hours in Spring 2013 Semester and by ringing in the fall semester with our biggest, most successful star party to date. We hosted the Third Annual Central Virginia Star Party, free and open to the community to encourage families to enjoy astronomy together. Nearly four hundred people of all ages attended, double the number from previous years. Joining with local astronomical societies, we offered an enlightening and exciting night with resources rarely accessible to the public, such as an IR camera and a portable planetarium. With numerous telescopes pointed at the sky, and a beautifully clear night with views of the Milky Way, the International Space Station, and numerous meteors, the star party was a fantastic opportunity to introduce many of our guests to the natural wonders of our night sky and enjoy some of the darkest skies on the eastern seaboard.

Standing Up for Learning: A Pilot Investigation on the Neurocognitive Benefits of Stand-Biased School Desks

2015-01-01

Standing desks have proven to be effective and viable solutions to combat sedentary behavior among children during the school day in studies around the world. However, little is known regarding the potential of such interventions on cognitive outcomes in children over time. The purpose of this pilot study was to determine the neurocognitive benefits, i.e., improvements in executive functioning and working memory, of stand-biased desks and explore any associated changes in frontal brain function. 34 freshman high school students were recruited for neurocognitive testing at two time points during the school year: (1) in the fall semester and (2) in the spring semester (after 27.57 (1.63) weeks of continued exposure). Executive function and working memory was evaluated using a computerized neurocognitive test battery, and brain activation patterns of the prefrontal cortex were obtained using functional near infrared spectroscopy. Continued utilization of the stand-biased desks was associated with significant improvements in executive function and working memory capabilities. Changes in corresponding brain activation patterns were also observed. These findings provide the first preliminary evidence on the neurocognitive benefits of standing desks, which to date have focused largely on energy expenditure. Findings obtained here can drive future research with larger samples and multiple schools, with comparison groups that may in turn implicate the importance of stand-biased desks, as simple environmental changes in classrooms, on enhancing children’s cognitive functioning that drive their cognitive development and impact educational outcomes.

2003-08-01

The response to superovulatory (SOV) and estrus synchronization (ES) treatments and the fertility of donor (n=68) and recipient (n=118) Saloia ewes was evaluated in the fall and spring breeding seasons. The proportion of acyclic ewes at treatment time was significantly higher in the spring than in the fall (42.6% versus 4.0%, P<0.00001). Donors treated with eCG had a significantly higher mean number of follicles over 5mm in diameter in the ovaries at embryo recovery and a significantly lower mean efficiency of recovery than FSH-treated ewes. These negative effects were more pronounced in the fall than in the spring, which resulted in a significantly lower mean number of total and fertilized ova recovered from eCG-treated ewes, compared to FSH donors in the fall, but not in the spring. Season had no significant effect on the ovulation rate and plasma P4 concentrations of recipients treated with a progestagen plus eCG combination. Although the recipient lambing and embryo survival rates were higher in the fall than in the spring the differences were not significant. No significant differences were observed in the ovulation rate or P4 concentrations of recipients that lambed compared to those that did not lamb. These preliminary results show that, in Portugal, response of Saloia ewes to SOV or ES treatments and donor fertility following the SOV treatment were similar in the spring and the fall, which suggests that in the spring acyclic ewes are in moderate anestrus. The effect of season on fertility following embryo transfer should be confirmed in further studies involving a larger number of animals. The semilaparoscopic transfer method reported here allowed lambing and embryo survival rates higher (although not significantly) than a standard surgical approach.

Atmospheric conditions during the spring and fall transitions in the coastal ocean off western United States

NASA Technical Reports Server (NTRS)

Strub, P. Ted; James, Corinne

1988-01-01

Atmospheric events which force the spring and fall oceanic transitions in the coastal ocean off the west coast of North America were examined by analyzing the records of adjusted sea level (ASL), coastal wind stress, sea level atmospheric pressure (SLP), and 500-mbar heights for the years 1971-1975 and 1980-1983. The records cover periods of 91 days, centered on the dates of the spring and fall transitions as determined from coastal ASL data. It was found that the dominant mode of the ASL and coastal wind stress are similar around the times of both the spring and fall transitions, and that the time series for these modes are highly correlated with one another. Principal estimator patterns show the spatial patterns of SLP which force the ASL and coastal wind stress during the transitions.

Methods for estimating selected spring and fall low-flow frequency statistics for ungaged stream sites in Iowa, based on data through June 2014

Eash, David A.; Barnes, Kimberlee K.; O'Shea, Padraic S.

2016-09-19

A statewide study was led to develop regression equations for estimating three selected spring and three selected fall low-flow frequency statistics for ungaged stream sites in Iowa. The estimation equations developed for the six low-flow frequency statistics include spring (April through June) 1-, 7-, and 30-day mean low flows for a recurrence interval of 10 years and fall (October through December) 1-, 7-, and 30-day mean low flows for a recurrence interval of 10 years. Estimates of the three selected spring statistics are provided for 241 U.S. Geological Survey continuous-record streamgages, and estimates of the three selected fall statistics are provided for 238 of these streamgages, using data through June 2014. Because only 9 years of fall streamflow record were available, three streamgages included in the development of the spring regression equations were not included in the development of the fall regression equations. Because of regulation, diversion, or urbanization, 30 of the 241 streamgages were not included in the development of the regression equations. The study area includes Iowa and adjacent areas within 50 miles of the Iowa border. Because trend analyses indicated statistically significant positive trends when considering the period of record for most of the streamgages, the longest, most recent period of record without a significant trend was determined for each streamgage for use in the study. Geographic information system software was used to measure 63 selected basin characteristics for each of the 211streamgages used to develop the regional regression equations. The study area was divided into three low-flow regions that were defined in a previous study for the development of regional regression equations.Because several streamgages included in the development of regional regression equations have estimates of zero flow calculated from observed streamflow for selected spring and fall low-flow frequency statistics, the final equations for the three low-flow regions were developed using two types of regression analyses—left-censored and generalized-least-squares regression analyses. A total of 211 streamgages were included in the development of nine spring regression equations—three equations for each of the three low-flow regions. A total of 208 streamgages were included in the development of nine fall regression equations—three equations for each of the three low-flow regions. A censoring threshold was used to develop 15 left-censored regression equations to estimate the three fall low-flow frequency statistics for each of the three low-flow regions and to estimate the three spring low-flow frequency statistics for the southern and northwest regions. For the northeast region, generalized-least-squares regression was used to develop three equations to estimate the three spring low-flow frequency statistics. For the northeast region, average standard errors of prediction range from 32.4 to 48.4 percent for the spring equations and average standard errors of estimate range from 56.4 to 73.8 percent for the fall equations. For the northwest region, average standard errors of estimate range from 58.9 to 62.1 percent for the spring equations and from 83.2 to 109.4 percent for the fall equations. For the southern region, average standard errors of estimate range from 43.2 to 64.0 percent for the spring equations and from 78.1 to 78.7 percent for the fall equations.The regression equations are applicable only to stream sites in Iowa with low flows not substantially affected by regulation, diversion, or urbanization and with basin characteristics within the range of those used to develop the equations. The regression equations will be implemented within the U.S. Geological Survey StreamStats Web-based geographic information system application. StreamStats allows users to click on any ungaged stream site and compute estimates of the six selected spring and fall low-flow statistics; in addition, 90-percent prediction intervals and the measured basin characteristics for the ungaged site are provided. StreamStats also allows users to click on any Iowa streamgage to obtain computed estimates for the six selected spring and fall low-flow statistics.

College students' understanding of stereochemistry: Difficulties in learning and critical junctures

NASA Astrophysics Data System (ADS)

Lyon, Gary Lester

Because stereochemistry is an important part of both high school and college chemistry curricula, a study of difficulties experienced by students in the learning of stereochemistry was undertaken in a one-semester college organic chemistry course. This study, conducted over the course of two semesters with more than two hundred students, utilized clinical interviews, concept maps, and student journals to identify these difficulties, which were then tabulated and categorized. Although student journals were not a productive source of information, the types of difficulties that emerged from the concept maps were compared and contrasted with those that emerged from the clinical interviews. Data from the concept maps were analyzed using Kendall's W, a nonparametric statistic that was deemed appropriate for determining concordance between individual concept maps. The correlation between values of Kendall's W for sets of concept maps and multiple choice questions designed to evaluate the content of these same maps was determined, with values of Pearson's r of .8093 (p = .051) and .7191 (p = .044) for the Fall, 1997 and Spring, 1998 semesters, respectively. These data were used to estimate the occurrence of critical junctures in the learning of stereochemistry, or points at which students must possess a certain framework of understanding of previous concepts in order to master new material (Trowbridge & Wandersee, 1994). One critical juncture was identified that occurred when the topics of enantiorners, absolute configuration, and inversion of configuration were introduced. Among the more important conclusions of this study to the learning of stereochemistry are the following. Both concept maps and interviews provided useful information regarding difficulties in the learning of stereochemistry; this information was complementary in some aspects and similar in others. Concept maps were useful in diagnosing difficulties in application of terms and definitions, whereas interviews were useful when seeking information about difficulties in the manipulation of chemical structures. Both concept maps and interviews were superior to student journals as tools to probe student difficulties in the learning of stereochemistry.

Adaptive genetic markers discriminate migratory runs of Chinook salmon (Oncorhynchus tshawytscha) amid continued gene flow

2013-01-01

Neutral genetic markers are routinely used to define distinct units within species that warrant discrete management. Human-induced changes to gene flow however may reduce the power of such an approach. We tested the efficiency of adaptive versus neutral genetic markers in differentiating temporally divergent migratory runs of Chinook salmon (Oncorhynchus tshawytscha) amid high gene flow owing to artificial propagation and habitat alteration. We compared seven putative migration timing genes to ten microsatellite loci in delineating three migratory groups of Chinook in the Feather River, CA: offspring of fall-run hatchery broodstock that returned as adults to freshwater in fall (fall run), spring-run offspring that returned in spring (spring run), and fall-run offspring that returned in spring (FRS). We found evidence for significant differentiation between the fall and federally listed threatened spring groups based on divergence at three circadian clock genes (OtsClock1b, OmyFbxw11, and Omy1009UW), but not neutral markers. We thus demonstrate the importance of genetic marker choice in resolving complex life history types. These findings directly impact conservation management strategies and add to previous evidence from Pacific and Atlantic salmon indicating that circadian clock genes influence migration timing.

The spring migration of adult North American Ospreys

USGS Publications Warehouse

Martell, Mark S.; Bierregaard, Richard O.; Washburn, Brian E.; Elliott, John E.; Henny, Charles J.; Kennedy, Robert S.; MacLeod, Iain

2014-01-01

Most North American Ospreys (Pandion haliaetus) are migratory, breeding in northern latitudes and migrating long distances to and from their wintering grounds in the tropics. Although fall migration patterns of North American Ospreys have been described and studied, very little has been published about the spring migration of these birds. We used satellite telemetry to: (1) determine the characteristics (timing, duration, migratory routes) of spring migrations of Ospreys; (2) determine if differences in spring migration patterns existed between sexes and among three breeding populations (east coast, midwestern, and western); and (3) compare consecutive fall and spring migrations of individual Ospreys. The median dates for departure from the wintering grounds and arrival on the breeding grounds did not differ significantly between adult male and female Ospreys. Compared to their fall migrations, all male and all east coast Ospreys spent fewer days on migration, fewer days in stopover periods along the migration route, traveled shorter distances overall, and traveled farther (on average) each day during spring. In contrast, fall and spring migration characteristics of all female and western Ospreys were similar. Our findings suggest that, although sex and breeding location might influence the spring migration strategy used by individual Ospreys, both males and females minimize the time spent on migration to ensure a timely arrival on the breeding grounds to establish or defend a nesting territory.

NASA Graduate Student Researchers Program Ronald E. McNair PhD Program

Howard, Sunnie

1998-01-01

The NASA Ronald E. McNair PHD Program was funded in September 1995. Implementation began during the spring of 1996. The deferment of the actual program initial semester enabled the program to continue support through the fall semester of 1998. This was accomplished by a no-cost extension from August 15, 1998 through December 31, 1998. There were 12 fellows supported by the program in 1996, 15 fellows in 1997, and 15 fellows 1998. Current program capacity is 15 fellows per funding support. Support for the academic outreach component began in spring 1998. The program was named the "Good Enough" Crew Activity (GECA) in honor of Dr. McNair's philosophy of everyone being good enough to achieve anything they want bad enough. The program currently enrolls 65 students from the third through the eight grades. The program is held 12 Saturdays per semester. The time is 9:00 AM to 12:30 PM each Saturday Morning. Program direction and facilitation is jointly administered with the PHD fellows and the Saturday Academy staff. Dr. John Kelly, REM-PHD Principal Investigator serves in a program oversight and leadership capacity. Ms. Sunnie Howard, The NASA REM-PHD Administrative Coordinator serves in an administrative and logistical capacity. Mr. Aaron Hatch, the NASA-AMES Liaison Officer, serve@'in a consultative and curriculum review capacity. The first recognition activity will be held on December 12, 1998, with the students, parents, faculty, PHD fellows, and other local student support services persons. Program outreach efforts are jointly supported by the NASA REM-PHD Program and the National Space Grant College and Fellowship Program. The Ph.D. program reached its first milestone in May 1998. North Carolina A&T State University graduated the first Ph.D. fellows. The first three Ph.D. Alumni were Ronald E. McNair PHD Program Fellows. It is hoped that this is just the beginning of a highly acclaimed doctoral program. The ultimate program success will be recognized when the program begins to graduate 15 fellows per year. The Ph.D. Program is only three and a half years old and the expectations of graduating PH.D's in that timeframe, is a phenomenal accomplishment for any program in the country. Since inception of the NASA REM-PHD program, tuitions and fees have increased. Stipend support was increased to offer the Ph.D. program on a competitive basis. These increases will place allocation restraints on r_ the current level of funding. These issues are being addressed in the proposal and will bear their own merit.

The Energetics of Transient Eddies in the Martian Northern Hemisphere

NASA Astrophysics Data System (ADS)

Battalio, Joseph Michael; Szunyogh, Istvan; Lemmon, Mark T.

2016-10-01

The energetics of northern hemisphere transient waves in the Mars Analysis Correction Data Assimilation is analyzed. Three periods between the fall and spring equinoxes (Ls=200°-230°, 255°-285°, and 330°-360°) during three Mars Years are selected to exemplify the fall, winter, and spring wave activity. Fall and spring eddy energetics is similar with some inter-annual and inter-seasonal variability, but winter eddy kinetic energy and its transport are strongly reduced in intensity as a result of the solsticial pause in eddy activity. Barotropic energy conversion acts as a sink of eddy kinetic energy throughout the northern hemisphere eddy period with little reduction in amplitude during the solsticial pause. Baroclinic energy conversion acts as a source in fall and spring but disappears during the winter period as a result of the stabilized vertical shear profile of the westerly jet around winter solstice.

Episodic acidification of a coastal plain stream in Virginia

USGS Publications Warehouse

O'Brien, A. K.; Eshleman, K.N.

1996-01-01

This study investigates the episodic acidification of Reedy Creek, a wetland-influenced coastal plain stream near Richmond, Virginia. Primary objectives of the study were to quantify the episodic variability of acid- base chemistry in Reedy Creek, to examine the seasonal variability in episodic response and to explain the hydrological and geochemical factors that contribute to episodic acidification. Chemical response was similar in each of the seven storms examined, however, the ranges in concentrations observed were commonly greater in summer/fall storms than in winter/spring storms. An increase in SO4/2- concentration with discharge was observed during all storms and peak concentration occurred at or near peak flow. Small increases in Mg2+, Ca2+, K+ concentrations and dissolved organic carbon (DOC) were observed during most storms. At the same time, ANC, Na+ and Cl- concentrations usually decreased with increasing discharge. In summer/fall storms, the absolute increase in SO4/2- concentration was one-third to 15 times the increase observed in winter/spring storms; the decrease in ANC during summer/fall storms was usually within the range of the decrease observed in winter/spring storms. In contrast, the decrease in Na+ and Cl- concentrations during winter/spring storms was much greater than that observed during summer/fall storms. Data show that while base flow anion deficit was higher in summer/fall than in winter/spring, anion deficit decreased during most summer/fall storms. In contrast, base flow anion deficit was lower in spring and winter, but increased during winter/spring storms. Increased SO4/2- concentration was the main cause of episodic acidification during storms at Reedy Creek, but increased anion deficit indicates organic acids may contribute to episodic acidification during winter/spring storms. Changes in SO4/2- concentration coincident with the hydrograph rise indicate quick routing of water through the watershed. Saturation overland flow appears to be the likely mechanism by which solutes are transported to the stream during storm flow.

Group dynamic and its effect on classroom climate, achievement, and time in lab in the organic chemistry laboratory classroom

NASA Astrophysics Data System (ADS)

Hall, Rachael S.

Despite the many studies on the benefits of cooperative learning, there is surprising little research into how the classroom as a whole changes when these cooperative groups are reassigned. In one section of CHEM 3011 in Fall 2013, students were allowed to pick their partner and kept the same partner all semester. In another section during the same semester, students were assigned a different partner for every wet lab and were allowed to pick their partners during the computer simulation labs. The students in both sections were given the "preferred" version of the Science Laboratory Environment Inventory (SLEI) at the beginning of the semester to elicit student preferences for the class environment, and the "actual" version of the SLEI and the Class Life Instrument at the end of the semester to determine what actually occurred during the semester. The students' interactions were recorded using an observational instrument developed specifically for this project. The students' responses to surveys, interactions, grades, and time in lab were analyzed for differences between the two sections. The results of this study will be discussed.

An integrative model of risk for high school disordered eating.

PubMed

Davis, Heather A; Smith, Gregory T

2018-06-21

Binge eating and purging behaviors are associated with significant harm and distress among adolescents. The process by which these behaviors develop (often in the high school years) is not fully understood. We tested the Acquired Preparedness (AP) model of risk involving transactions among biological, personality, and psychosocial factors to predict binge eating and purging behavior in a sample of 1,906 children assessed in the spring of 5th grade (the last year of elementary school), the fall of 6th grade (the first year of middle school), spring of 6th grade, and spring of 10th grade (second year of high school). Pubertal onset in spring of 5th grade predicted increases in negative urgency, but not negative affect, in the fall of 6th grade. Negative urgency in the fall of 6th grade predicted increases in expectancies for reinforcement from eating in the spring of 6th grade, which in turn predicted increases in binge eating behavior in the spring of 10th grade. Negative affect in the fall of 6th grade predicted increases in thinness expectancies in the spring of 6th grade, which in turn predicted increases in purging in the spring of 10th grade. Results demonstrate similarities and differences in the development of these two different bulimic behaviors. Intervention efforts targeting the risk factors evident in this model may prove fruitful in the treatment of eating disorders characterized by binge eating and purging.

Perfectionism and longitudinal patterns of stress for STEM majors: Implications for academic performance.

PubMed

Rice, Kenneth G; Ray, Merideth E; Davis, Don E; DeBlaere, Cirleen; Ashby, Jeffrey S

2015-10-01

Complementary hypotheses suggest that perfectionism may (a) cause later stress (stress generation) and (b) moderate the effects of stress on subsequent outcomes (stress enhancement). The present study tested these hypotheses with a sample of 432 first-time college freshmen pursuing science, technology, engineering, and math (STEM) majors. Students completed baseline perfectionism scales and repeated measures for perceived academic stress at monthly intervals 3 times in the fall semester and 3 times in the spring semester. Course grade data from institutional records were used to calculate first-year STEM grade point average (GPA) as the distal outcome in analyses. Gender, high school GPA, SAT math scores, and university were covariates. Latent profile analyses supported adaptive, maladaptive, and nonperfectionist classes and latent class growth mixture models identified distinctly low, moderate, and high patterns of academic stress over the year. Latent transition analyses indicated that maladaptive perfectionists were likely to experience moderate or high stress (none transitioned to low stress), and adaptive perfectionists were likely to have low or moderate stress (only 4% transitioned to high stress). Women were substantially more likely than male maladaptive perfectionists to experience high stress. Low-stressed adaptive perfectionists followed by moderately stressed maladaptive perfectionists had relatively higher GPAs than other groups. Subgroups of perfectionists who transitioned to the next higher stress level had substantially lower GPAs than other groups. Overall, results were consistent with stress-generation and stress-enhancement hypotheses regarding perfectionists. Findings suggested implications for prevention and intervention with perfectionistic STEM students that should be implemented early in their college experience. (c) 2015 APA, all rights reserved).

The development and assessment of constructivist-based curriculum changes in a university general biology laboratory course

NASA Astrophysics Data System (ADS)

Herron, Sherry Shelton

1999-11-01

This study describes the processes involved in transforming the curriculum of the second semester general biology laboratory course for science majors, BSC 111L, at the University of Southern Mississippi from one based on the behaviorist model of teaching and learning to one based on the constructivist model. The study encompasses pilot and research phases. During the pilot phase conducted fall semester of 1997, the researcher presented to graduate teaching assistants an overview of the need for curriculum reform and some of the theoretical underpinnings for the movement. The researcher worked with all of the general biology teaching assistants to determine factors they considered supportive of the effort, identified specific goals and exercises, and developed a mission statement. The researcher then worked with two of the teaching assistants to write the new curriculum materials and pilot them in a designated laboratory section each week. During the research phase, the researcher facilitated the use of constructivist teaching methods and interviewed the teaching assistants during weekly group meetings. The researcher videotaped and observed the laboratories at various times throughout spring semester of 1998. Student responses to survey questions about the laboratories were collected during the observation sessions. Data derived from self-assessments on teaching beliefs completed by the teaching assistants, interview transcripts, videotaped laboratory sessions, and student surveys were used to assess the effectiveness of the new curriculum and the intervention program. It was observed that despite being given the same instructions, curriculum, and materials, each teaching assistant conducted his laboratory section in a unique way and rarely conducted the complete laboratory in the intended manner. It was also observed that one TA in particular needed more training in interpersonal skill development and content than was provided during the weekly intervention sessions. However, it was evident that constructivist teaching methods were being learned and that constructivist goals were being realized. Strengths and weaknesses of the curriculum materials were identified and extensive revisions were made by the researcher prior to the next semester. Finally, recommendations pertinent to the student survey used in this study (the Student Outcome Assessment Rubric) were made, and the need for more pedagogical instruction for teaching assistants and a mechanism to integrate lecture materials to the laboratory experience was described.

Behavioral self-concept as predictor of teen drinking behaviors.

PubMed

Dudovitz, Rebecca N; Li, Ning; Chung, Paul J

2013-01-01

Adolescence is a critical developmental period for self-concept (role identity). Cross-sectional studies link self-concept's behavioral conduct domain (whether teens perceive themselves as delinquent) with adolescent substance use. If self-concept actually drives substance use, then it may be an important target for intervention. In this study, we used longitudinal data from 1 school year to examine whether behavioral self-concept predicts teen drinking behaviors or vice versa. A total of 291 students from a large, predominantly Latino public high school completed a confidential computerized survey in the fall and spring of their 9th grade year. Survey measures included the frequency of alcohol use, binge drinking and at-school alcohol use in the previous 30 days; and the Harter Self-Perception Profile for Adolescents behavioral conduct subscale. Multiple regressions were performed to test whether fall self-concept predicted the frequency and type of spring drinking behavior, and whether the frequency and type of fall drinking predicted spring self-concept. Fall behavioral self-concept predicted both the frequency and type of spring drinking. Students with low versus high fall self-concept had a predicted probability of 31% versus 20% for any drinking, 20% versus 8% for binge drinking and 14% versus 4% for at-school drinking in the spring. However, neither the frequency nor the type of fall drinking significantly predicted spring self-concept. Low behavioral self-concept may precede or perhaps even drive adolescent drinking. If these results are confirmed, then prevention efforts might be enhanced by targeting high-risk teens for interventions that help develop a healthy behavioral self-concept.

Multi-method assessments of sleep over the transition to college and the associations with depression and anxiety symptoms.

PubMed

Doane, Leah D; Gress-Smith, Jenna L; Breitenstein, Reagan S

2015-02-01

A growing body of research has demonstrated links between sleep problems and symptoms of depression and anxiety in community and clinical samples of adolescents and young adults. Scant longitudinal research, however, has examined reciprocal associations over socio-contextual shifts such as the transition to college. Using multiple methods of assessment (e.g., actigraphy, subjective report), the current study assessed whether sleep quantity, quality or variability changed over the transition to college and investigated the potential cross-lagged relationships between adolescents' sleep and symptoms of anxiety and depression. The participants (N = 82; 24% male) were studied at three time points over approximately 1 year: spring of their senior year of high school (T1), fall of their first year of college (T2), and spring of their first year of college (T3). Sleep minutes, sleep efficiency, wake time variability and anxiety increased over the transition to college. Subjective reports of sleep problems decreased. Cross-lagged panel models indicated significant relationships between subjective sleep quality and anxiety symptoms over time where subjective sleep problems at T1 were associated with anxiety at T2, and anxiety at T2 was associated with subjective sleep problems at T3. In contrast, greater depressive symptoms at T1 preceded increases in subjective sleep problems, sleep latency and sleep start time variability at T2. Importantly, there were concurrent associations between symptoms of anxiety or depression at T2 and sleep efficiency, sleep start time variability, and subjective sleep problems. These findings suggest that, overall, sleep quantity and quality improved over the transition to college, although the overall amounts of sleep were still below developmental recommendations. However, for some youth, the first semester of college may be a sensitive period for both sleep problems and symptoms of anxiety. In contrast, depressive symptoms were stable across time but were associated with worsening sleep problems in the first semester of college. Implications for future prevention and intervention programs should include strategies to help youth cope effectively with adjustment like increased sleep variability and symptoms of anxiety associated with the transition to college.

Early school competence: the roles of sex-segregated play and effortful control.

Fabes, Richard A; Martin, Carol Lynn; Hanish, Laura D; Anders, Mary C; Madden-Derdich, Debra A

2003-09-01

The purpose of this research was to examine the role that young children's same-sex peer interactions play in influencing early school competence. The authors also examined the degree to which effortful control (EC) moderated these relations. The same-sex play preferences of 98 young children (50 boys and 48 girls; mean age = 54.77 months) were observed during the fall semester. At the end of the fall semester, one set of teachers reported on children's EC, and at the end of the following springsemester, another set reported on children's school competence (social, academic, and perceptual-motor). Results revealed that EC moderated the relations of children's same-sex play to their school competence. These patterns differed for boys and girls such that same-sex play was positively related to school outcomes for boys high in EC and for girls low in EC.

Collegiate-based emergency medical service: impact on alcohol-related emergency department transports at a small liberal arts college.

PubMed

Rosen, Joshua B; Olson, Mark H; Kelly, Marianne

2012-01-01

The authors examined the impact of a collegiate-based emergency medical service (CBEMS) on the frequency of emergency department (ED) transports. Students transported to the ED for acute alcohol intoxication during the Fall 2008 and the Fall 2009 semesters (N = 50). The frequency of students receiving transportation to a hospital ED and the reported blood alcohol content (BAC) levels during the initial operational semester of the CBEMS were compared to those values over the same time period the previous year. More than twice the number of students was transported to the ED following the introduction of CBEMS. There was no change in mean BAC levels. CBEMS could promote a culture conducive to increased reporting behavior, which makes the campus safer. Similar BAC levels suggest that the degree of intoxication was similar for the 2 reporting periods, but students sought emergency assistance more frequently following the inception of CBEMS.

2018-01-01

In order to develop new open pollinating cultivars of broccoli for organic farming, two experiments were conducted during fall 2015 and spring 2016. This study was aimed at comparing the agronomic performance of eleven new open pollinating breeding lines of broccoli to introduce new lines and to test their seasonal suitability for organic farming. Field experiments were carried out at the organic research station Kleinhohenheim of the University of Hohenheim (Stuttgart-Germany). Different agronomic traits total biomass fresh weight, head fresh weight, head diameter, hollow-stem, fresh weight harvest index and marketable yield were assessed together with commercial control cultivars. The data from both experiments were analyzed using a two-stage mixed model approach. In our study, genotype, growing season and their interaction had significant effects on most traits. Plants belonging to the fall growing season had bigger sizes in comparison to spring with significantly (p< 0.0001) higher biomass fresh weight. Some experimental lines had significant lower head fresh weight in spring in comparison to the fall season. The high temperature during the harvest period for the spring season affected the yield negatively through decreasing the firmness of broccoli heads. The low average minimum temperatures during the spring growing season lead to low biomass fresh weight but high fresh weight harvest index. Testing the seasonal suitability of all open pollinating lines showed that the considered fall season was better for broccoli production. However, the change in yield between the fall and the spring growing season was not significant for "Line 701" and "CHE-MIC". Considering the expression of different agronomic traits, "CHE-GRE-G", "Calinaro" and "CAN-SPB" performed the best in the fall growing season, and "CHE-GRE-G", "CHE-GRE-A", "CHE-BAL-A" and "CHE-MIC" and "Line 701" were best in the spring growing season, specifically due to the highest marketable yield and proportion of marketable heads.

A comparison of burn season effects on nesting birds in North Dakota mixed-grass prairie

Higgins, K.F.

1986-01-01

During 1982-1985, the effects of single spring and fall burn treatments on ground nesting birds and residual cover were studied on five paired areas of native mixed-grass prairie in northwestern Stutsman County, ND. Annually, visual obstruction readings to index the height-density of residual cover were taken once and nest searches were made four times on each area. Residual nesting cover on fall burn plots averaged taller and denser than on spring burn plots during post-fire growing years 2-4. A total of 259 duck nests and 63 nests of non-passerine birds were found during the four years. Duck nesting success was significantly greater (P < 0.05) in fall burn plots than in spring burn plots for all species and years combined. Too few nests of other bird species were found for valid comparisons. Results suggest that vegetation structure and duck nesting response to spring and fall burns became similar again by the third post-fire growing season.

Within the general university environment, students' perceived self-efficacy has been widely studied and findings suggest it plays a role in student success. The current research adapted a self-efficacy survey, from the ``Self-Efficacy for Learning Performance'' subscale of the Motivated Learning Strategies Questionnaire and administered it to the introductory, calculus-based physics classes (N=1005) over the fall 2015 and spring 2016 semesters. This assessment measured students' self-efficacy in domains including the physics class, other science and mathematics classes, and their intended future career. The effect of gender was explored with the only significant gender difference (p < . 001) existing within the physics domain. A hierarchical linear regression analysis indicated that this gender difference was not explained by a student's performance which was measured by test average. However, a mediation analysis showed that students' overall academic self-efficacy, measured by their math and science self-efficacy, acts as a mediator for the effect of test average on self-efficacy towards the physics class domain. This mediation effect was significant for both female (p < . 01) and male students (p < . 001) however, it was more pronounced for male students.

2012-01-01

Lesbian, gay, and bisexual (i.e., sexual minority) populations have increased prevalence of both self-injurious and suicidal behaviors, but reasons for these disparities are poorly understood. Objective To test the association between socially-based stressors (e.g., victimization, discrimination) and self-injurious behavior, suicide ideation, and suicide attempt. Participants A national sample of college-attending 18- to 24-year-olds. Methods Random or census samples from post-secondary educational institutions that administered the National College Health Assessment during the Fall 2008 and Spring 2009 semesters. Results Sexual minorities reported more socially-based stressors than heterosexuals. Bisexuals exhibited greatest prevalence of self-injurious and suicidal behaviors. In adjusted models, intimate partner violence was most consistently associated with self-injurious behaviros. Conclusions Sexual minorities' elevated risks of self-injurious and suicidal behaviors may stem from higher exposure to socially-based stressors. Within-group differences among sexual minorities offer insight to specific risk factors that may contribute to elevated self-injurious and suicidal behaviors in sexual minority populations.

Jezorek, Ian G.; Connolly, Patrick J.; Munz, Carrie S.; Dixon, Chris

2011-01-01

Executive Summary: This project was designed to document habitat conditions and populations of native and non-native fish within the 8-kilometer Condor Canyon section of Meadow Valley Wash, Nevada, with an emphasis on Big Spring spinedace (Lepidomeda mollispinis pratensis). Other native fish present were speckled dace (Rhinichthys osculus) and desert sucker (Catostomus clarki). Big Spring spinedace were known to exist only within this drainage and were known to have been extirpated from a portion of their former habitat located downstream of Condor Canyon. Because of this extirpation and the limited distribution of Big Spring spinedace, the U.S. Fish and Wildlife Service listed this species as threatened under the Endangered Species Act in 1985. Prior to our effort, little was known about Big Spring spinedace populations or life histories and habitat associations. In 2008, personnel from the U.S. Geological Survey's Columbia River Research Laboratory began surveys of Meadow Valley Wash in Condor Canyon. Habitat surveys characterized numerous variables within 13 reaches, thermologgers were deployed at 9 locations to record water temperatures, and fish populations were surveyed at 22 individual sites. Additionally, fish were tagged with Passive Integrated Transponder (PIT) tags, which allowed movement and growth information to be collected on individual fish. The movements of tagged fish were monitored with a combination of recapture events and stationary in-stream antennas, which detected tagged fish. Meadow Valley Wash within Condor Canyon was divided by a 12-meter (m) waterfall known as Delmue Falls. About 6,100 m of stream were surveyed downstream of the falls and about 2,200 m of stream were surveyed upstream of the falls. Although about three-quarters of the surveyed stream length was downstream of Delmue Falls, the highest densities and abundance of native fish were upstream of the falls. Big Spring spinedace and desert sucker populations were highest near the upper end of Condor Canyon, where a tributary known as Kill Wash, and several springs, contribute flow and moderate high and low water temperature. Kill Wash and the area around its confluence with Meadow Valley Wash appeared important for spawning of all three native species. Detections of PIT-tagged fish indicated that there were substantial movements to this area during the spring. Our surveys included about 700 m of Meadow Valley Wash upstream of Kill Wash. A small falls about 2 m high was about 560 m upstream of Kill Wash. This falls is likely a barrier to upstream fish movement at most flows. Populations of all three native species were found upstream of this small falls. Age-0 fish of all three species were present, indicating successful spawning. The maximum upstream extent of native fish within Meadow Valley Wash was not determined. Our surveys included about 700 m of Meadow Valley Wash upstream of Kill Wash. A small falls about 2 m high was about 560 m upstream of Kill Wash. This falls is likely a barrier to upstream fish movement at most flows. Populations of all three native species were found upstream of this small falls. Age-0 fish of all three species were present, indicating successful spawning. The maximum upstream extent of native fish within Meadow Valley Wash was not determined. A population of non-native rainbow trout (Oncorhynchus mykiss) was found within the 2,000 m of stream immediately downstream of Delmue Falls. Non-native crayfish were very common both upstream and downstream of Delmue Falls. We were not able to quantify crayfish populations, but they compose a significant portion of the biomass of aquatic species in Condor Canyon. There were some distinctive habitat features that may have favored native fish upstream of Delmue Falls. Upstream of the falls, water temperatures were moderated by inputs from springs, turbidity was lower, pool habitat was more prevalent, substrate heterogeneity was higher, and there was less fine sediment than

For more than 20 years, the American Meteorological Society (AMS) has been enhancing K-12 teacher preparation and practice, and ultimately student learning through the DataStreme Project. DataStreme Atmosphere, Ocean, and Earth's Climate System (ECS), which are in close alignment with NGSS, empower teachers to implement STEM concepts in their classrooms using real-world data to deepen understanding of core science concepts and raise scientific literacy. For example, DataStreme ECS participants use the AMS Conceptual Climate Energy Model (CCEM) to explore radiative equilibrium. Then, participants use real-world NOAA data within the AMS Climate at a Glance (CAG) app to determine whether or not there is objective evidence consistent with climate change. Both the CCEM and CAG app enable participants to investigate concepts as scientists do, thereby aligning with Dimension 1 of NGSS. This presentation will highlight other ways in which DataStreme ECS aligns with the four disciplinary areas of NGSS. DataStreme courses are offered each fall and spring semester by Local Implementation Teams (LITs) across the country in coordination with AMS Education Program scientists and educators. In 2017, the AMS Education Program entered into a new agreement with California University of Pennsylvania to serve as their institutional partner for DataStreme to offer tuition-free graduate credits to participants. Some changes have already occurred and there are many opportunities for further enhancement. Most noticeably to begin, DataStreme course resources are now available to participants in all 50 states and U.S. territories through a learning management system (LMS). The use of a LMS enables LITs the opportunity to better engage their participants through online discussion boards, video assignments, shared dropbox uploads, digital assessment tools and rubrics, and much more. The Fall 2017 semester was the first term to exploit the Desire to Learn (D2L) platform for course implementation. This presentation will include feedback and lessons learned from early use of new pedagogical tools. The future of teacher professional development opportunities via AMS DataStreme courses is bright as it evolves under new leadership and leverages new tools while staying rooted in its mission to increase public scientific literacy.

Investigating Changes in Students’ Attitudes Towards Science During an Adaptive Online Astrobiology Course

Online education is an emergent sector of formal education and Arizona State University (ASU) is a leader in offering online courses. One that garners very strong positive feedback on student surveys is Habitable Worlds, which is an interdisciplinary online science course offered every semester since Fall 2011. Primary goals of this course are to teach understanding of scientific reasoning and practices by using principles from trans-disciplinary research in astrobiology. To examine course outcomes we administered the Classroom Undergraduate Research Experience (CURE) survey, which has been previously developed to measure student experiences. Here we use the survey for the first time for an online course. The survey was taken before and after completing the course during the Fall 2014 and Spring 2015 semesters (N = 544). Here, we present students’ views of science represented by 22 questions on the survey. For the questions, students responded either "not applicable," "strongly disagree," "disagree," "neutral," "agree," or "strongly agree." In order to interpret the data, we divided the questions into three broader categories for analysis: students’ understanding of the scientific process, students’ scientific self-efficacy and students’ views on science teaching. We study how the sample of students changed their responses to each of the questions as a group by using a paired-samples sign test to gauge the statistical significance of the difference between pre and post responses. We further analyze how individual students changed their responses. For example, we designated a change from “strongly disagree” to “disagree” differently than a change from “agree” to “disagree” since the latter indicated a notable change in the student’s opinion. We found statistically significant changes on 12 of the 22 questions. These early results indicate that there are measurable changes on several identified course objectives. By measuring changes that occurred to the whole group of students as well as identifying in detail what type of changes occurred from student to student for each question, we will be able to improve future offerings of the course as well as to make broader conclusions about online science education.

Bioaccumulation of selenium by the Bryophyte Hygrohypnum ochraceum in the Fountain Creek Watershed, Colorado.

PubMed

Herrmann, S J; Turner, J A; Carsella, J S; Lehmpuhl, D W; Nimmo, D R

2012-12-01

Aquatic bryophytes, Hygrohypnum ochraceum, were deployed "in situ" at 14 sites in the Fountain Creek Watershed, spring and fall, 2007 to study selenium (Se) accumulation. Dissolved, total, and pore (sediment derived) water samples were collected and water quality parameters determined while plants were exposed to the water for 10 days. There was a trend showing plant tissue-Se uptake with distance downstream and we found a strong correlation between Se in the water with total hardness in both seasons. There was a modest association between Se-uptake in plants with hardness in the spring of 2007 but not the fall. Plants bioconcentrated Se from the water by a factor of 5.8 × 10(3) at Green Mountain Falls and 1.5 × 10(4) at Manitou Springs in the fall of 2007. Both are examples of the bioconcentration abilities of the plants, primarily in the upper reaches of the watershed where bioconcentration factors were highest. However, the mean minima and maxima of Se in the plants in each of the three watershed segments appeared similar during both seasons. We found direct relationships between the pore and dissolved Se in water in the spring (R (2) = 0.84) and fall (R (2) = 0.95) and dissolved Se and total hardness in the spring and fall (R (2) = 0.92). The data indicate that H. ochraceum was a suitable indicator of Se bioavailability and Se uptake in other trophic levels in the Fountain Creek Watershed based on a subsequent study of Se accumulation in fish tissues at all 14 sites.

The Timing of Arctic Sea Ice Advance and Retreat as an Indicator of Ice-Dependent Marine Mammal Habitat

NASA Astrophysics Data System (ADS)

Stern, H. L.; Laidre, K. L.

2013-12-01

The Arctic is widely recognized as the front line of climate change. Arctic air temperature is rising at twice the global average rate, and the sea-ice cover is shrinking and thinning, with total disappearance of summer sea ice projected to occur in a matter of decades. Arctic marine mammals such as polar bears, seals, walruses, belugas, narwhals, and bowhead whales depend on the sea-ice cover as an integral part of their existence. While the downward trend in sea-ice extent in a given month is an often-used metric for quantifying physical changes in the ice cover, it is not the most relevant measure for characterizing changes in the sea-ice habitat of marine mammals. Species that depend on sea ice are behaviorally tied to the annual retreat of sea ice in the spring and advance in the fall. Changes in the timing of the spring retreat and the fall advance are more relevant to Arctic marine species than changes in the areal sea-ice coverage in a particular month of the year. Many ecologically important regions of the Arctic are essentially ice-covered in winter and ice-free in summer, and will probably remain so for a long time into the future. But the dates of sea-ice retreat in spring and advance in fall are key indicators of climate change for ice-dependent marine mammals. We use daily sea-ice concentration data derived from satellite passive microwave sensors to calculate the dates of sea-ice retreat in spring and advance in fall in 12 regions of the Arctic for each year from 1979 through 2013. The regions include the peripheral seas around the Arctic Ocean (Beaufort, Chukchi, East Siberian, Laptev, Kara, Barents), the Canadian Arctic Archipelago, and the marginal seas (Okhotsk, Bering, East Greenland, Baffin Bay, Hudson Bay). We find that in 11 of the 12 regions (all except the Bering Sea), sea ice is retreating earlier in spring and advancing later in fall. Rates of spring retreat range from -5 to -8 days/decade, and rates of fall advance range from +5 to +9 days/decade, with steeper trends in the Barents Sea. Thus the season of sparse sea-ice coverage is lengthening by about 2 weeks/decade, or 6 weeks over the period of record. The trends in all 11 regions are statistically significant. The dates of sea-ice retreat in spring and advance in fall are negatively correlated: an early spring retreat tends to be followed by a late fall advance, and vice-versa. This is a manifestation of the ice-albedo feedback: with an early sea-ice retreat, the ocean has more time to absorb heat from the sun. The extra heat is stored in the upper ocean through the summer, and must be released to the atmosphere in the fall before sea ice can begin to form, thus delaying fall freeze-up. This relationship gives some predictive power to the date of fall sea-ice advance, given the date of spring retreat. Changes have been reported in the seasonal distribution of polar bears, walruses, seals, and whales in the Arctic. We are developing metrics for potential use by the U.S. National Climate Assessment based on the timing of sea-ice advance and retreat, to be used as indicators of ice-dependent marine mammal habitat. Future work will examine connections between the phenology of Arctic marine mammals and the sea-ice indicators.

On December 22, 2008, over 4 million cubic meters of fly ash slurry was released into the Emory River when a dike surrounding a solid waste containment area at the Tennessee Valley Authority's (TVA) Kingston Fossil Plant ruptured. One component of TVA's response to the spill is a biological monitoring program to assess short- and long-term ecological responses to the ash and associated chemicals, including studies on fish health and contaminant bioaccumulation. These studies were initiated in early Spring 2009 for the purposes of: (1) documenting the levels of fly ash-associated metals in various tissues of representative sentinel fish speciesmore » in the area of the fly ash spill, (2) determining if exposure to fly ash-associated metals causes short, intermediate, or long-term health effects on these sentinel fish species, (3) assessing if there are causal relationships between exposure to metals and health effects on fish, (4) evaluating, along with information from other ecological and physicochemical studies, the nature and route of contaminant transfer though food chains into higher level consumers, (5) providing important information for the Ecological Risk Assessment (ERA) for the Kingston fly ash project, and (6) serving as an important technology information transfer or model study focused on how to best evaluate the environmental effects of fly ash (and related environmental stressors), not only at the Kingston site, but also at sites on other aquatic systems where coal-fired generating stations are located. This report presents the results of the first two years of the fish health study. To date, fish health and bioaccumulation studies have been conducted from Spring 2009 though Fall 2011 and includes 6 seasonal studies: Spring 2009, Fall 2009, Spring 2010, Fall 2010, Spring 2011, and Fall 2011. Both the Spring and Fall studies have focused on 3-4 sentinel fish species that represent different feeding habits, behaviors, and home ranges. In addition to fish health and bioaccumulation, the Spring investigations also included reproductive integrity studies on the same fish used for bioaccumulation and fish health. In this report, results of the fish health studies from Spring 2009 through Fall 2010 are presented while an associated report will present the fish reproductive studies conducted during Spring 2009 and Spring 2010. A report on fish bioaccumulation was submitted to TVA in June 2011. The fish health study conducted in conjunction with the bioaccumulation and reproductive study is critical for assessing and evaluating possible causal relationships between contaminant exposure (bioaccumulation) and the response of fish to exposure as reflected by the various measurements of fish health.« less

From Fall to Spring, or Spring to Fall? Seasonal Cholera Transmission Cycles and Implications for Climate Change

NASA Astrophysics Data System (ADS)

Akanda, A. S.; Jutla, A. S.; Huq, A.; Colwell, R.; Islam, S.; WE Reason

2010-12-01

Cholera remains a major public health threat in many developing countries around the world. The striking seasonality and the annual recurrence of this infectious disease in endemic areas continues to be of considerable interest to scientists and public health workers. Despite major advances in the ecological, and microbiological understanding of Vibrio cholerae, the causative agent, the role of underlying macro-scale hydroclimatic processes in propagating the disease in different seasons and years is not well understood. The incidence of cholera in the Bengal Delta region, the ‘native homeland’ of cholera, shows distinct biannual peaks in the southern floodplains, as opposed to single annual peaks in coastal areas and the northern parts of Bangladesh, as well as other cholera-endemic regions in the world. A coupled analysis of the regional hydroclimate and cholera incidence reveals a strong association of the spatio-temporal variability of incidence peaks with seasonal processes and extreme events. At a seasonal scale, the cycles indicate a spring-fall transmission pattern, contrary to the prevalent notion of a fall-spring transmission cycle. We show that the asymmetric seasonal hydroclimatology affects regional cholera dynamics by providing a coastal growth environment for bacteria in spring, while propagating transmission to fall by flooding. This seasonal interpretation of the progression of cholera has important implications, for formulating effective cholera intervention and mitigation efforts through improved water management and understanding the impacts of changing climate patterns on seasonal cholera transmission.

2004-07-01

Seasonal effects on reproduction are more dramatic in Bos indicus than Bos taurus cattle. This experiment evaluated reproductive development of fall- (n=7) versus spring- (n = 10) born Brahman bulls to determine if season of birth affects reproductive development. Measurements of growth and reproductive development began after weaning and continued at bi-weekly intervals until each bull reached sexual maturity. Different stages of sexual development were classified according to characteristics of the ejaculate and included first sperm in the ejaculate, puberty (> 50 x 10(6) sperm/ejaculate), and sexual maturity (two ejaculates with > 500 = 10(6) sperm/ejaculate). Average daily increases in all measured traits were similar in fall- and spring-born bulls and there were no differences in age, body weight, scrotal circumference, or paired testis volume between groups at first sperm or puberty. However, fall-born bulls were older (P < 0.05) than spring-born bulls at sexual maturity (553 days versus 481 days, respectively) as the interval between puberty and sexual maturity was longer (P < 0.05) in fall- than in spring-born bulls (82 days versus 54 days, respectively). The prolonged interval between puberty and sexual maturity in fall-born calves coincided with a short photoperiod (winter) whereas the short interval between puberty and sexual maturity in spring-born calves coincided with a long photoperiod (summer). In conclusion, season of birth affected sexual development; photoperiod might be involved in regulating testicular function immediately after puberty in Brahman bulls.

[Effects of different disturbance modes on the morphological characteristics and aboveground biomass of Alhagi sparsifolia in oasis-desert ecotone].

Taking Cele oasis at the southern fringe of Taklimakan Desert as a case, this paper studied the effects of different disturbances (burning in spring, cutting in spring, and cutting in fall) on the morphological characteristics and aboveground biomass of natural vegetation Alhagi sparsifolia in the ecotone of oasis-desert. Burning in spring decreased the A. sparsifolia plant height, crown width, and biomass significantly, being harmful to the regeneration and growth of the vegetation. Cutting in spring decreased the A. sparsifolia plant height, crown width, and biomass but increased the leaf biomass, thorn length, and thorn diameter, whereas cutting in fall decreased the plant height and crown width but increased the ramification amount and biomass of A. sparsifolia. Moderate cutting in fall could benefit the protection of A. sparsifolia at the southern fringe of Taklimakan Desert.

Data are presented on the concentrations of alkylphenol and alkylphenol ethoxylates (APEs) and persistent organic compounds in largemouth bass collected from a waste-water dominated stream in downtown Chicago. The fish residue concentrations of APEs are compared to concentrations of the APEs in the water that were collected at weekly intervals over two months bracketing the fall (2006) and a spring (2007) fish collection. The concentrations of APEs were significantly higher in the spring-collected fish (5.42 μg/g) versus the fall (0.99 μg/g) tand these differences were shared by differences in the water concentrations (spring — 11.47 versus fall — 3.44 μg/L). The differences in water concentration were negatively correlated with water temperatures observed over the two sampling times. Fish residue concentrations of persistent organic compounds (PCBs, PBDEs, toxaphene, and many legacy pesticides including the DDT family) did not vary from fall to spring. Some of these residue concentrations were comparable to the highest NPE (nonylphenol ethoxylate) homologue concentrations, e.g. NP1EO was 3.5 μg/g in the bass for the spring, the PBDE-congener 47 and p,p′-DDE averaged 1.0 μg/g and 0.5 μg/g, respectively, over both seasons. All the other persistent single-analyte concentrations were lower. Biological endpoints for endocrine effects measured in the same fish showed that there was an apparent positive correlation for physiological effects based on increased vitellogenin levels in males versus concentration of NPEs; however there were no observable histological differences in fall versus spring fish samples.

Chromosome regions affecting grain yield, grain yield components and plant water status were identified and validated in fall-sown spring wheats grown under full and limited irrigation. Increases in wheat production are required to feed a growing human population. To understand the genetic basis of grain yield in fall-sown spring wheats, we performed a genome-wide association study (GWAS) including 262 photoperiod-insensitive spring wheat accessions grown under full and limited irrigation treatments. Analysis of molecular variance showed that 4.1% of the total variation in the panel was partitioned among accessions originally developed under fall-sowing or spring-sowing conditions, 11.7% among breeding programs within sowing times and 84.2% among accessions within breeding programs. We first identified QTL for grain yield, yield components and plant water status that were significant in at least three environments in the GWAS, and then selected those that were also significant in at least two environments in a panel of eight biparental mapping populations. We identified and validated 14 QTL for grain yield, 15 for number of spikelets per spike, one for kernel number per spike, 11 for kernel weight and 9 for water status, which were not associated with differences in plant height or heading date. We detected significant correlations among traits and colocated QTL that were consistent with those correlations. Among those, grain yield and plant water status were negatively correlated in all environments, and six QTL for these traits were colocated or tightly linked (< 1 cM). QTL identified and validated in this study provide useful information for the improvement of fall-sown spring wheats under full and limited irrigation.

In order to develop new open pollinating cultivars of broccoli for organic farming, two experiments were conducted during fall 2015 and spring 2016. This study was aimed at comparing the agronomic performance of eleven new open pollinating breeding lines of broccoli to introduce new lines and to test their seasonal suitability for organic farming. Field experiments were carried out at the organic research station Kleinhohenheim of the University of Hohenheim (Stuttgart-Germany). Different agronomic traits total biomass fresh weight, head fresh weight, head diameter, hollow-stem, fresh weight harvest index and marketable yield were assessed together with commercial control cultivars. The data from both experiments were analyzed using a two-stage mixed model approach. In our study, genotype, growing season and their interaction had significant effects on most traits. Plants belonging to the fall growing season had bigger sizes in comparison to spring with significantly (p< 0.0001) higher biomass fresh weight. Some experimental lines had significant lower head fresh weight in spring in comparison to the fall season. The high temperature during the harvest period for the spring season affected the yield negatively through decreasing the firmness of broccoli heads. The low average minimum temperatures during the spring growing season lead to low biomass fresh weight but high fresh weight harvest index. Testing the seasonal suitability of all open pollinating lines showed that the considered fall season was better for broccoli production. However, the change in yield between the fall and the spring growing season was not significant for “Line 701” and “CHE-MIC”. Considering the expression of different agronomic traits, “CHE-GRE-G”, “Calinaro” and “CAN-SPB” performed the best in the fall growing season, and “CHE-GRE-G”, “CHE-GRE-A”, “CHE-BAL-A” and “CHE-MIC” and “Line 701” were best in the spring growing season, specifically due to the highest marketable yield and proportion of marketable heads.

Genetic and environmental influences on cold hardiness of native and introduced riparian trees

Friedman, Jonathan M.; Roelle, James E.; Cade, Brian S.

2012-01-01

To explore latitudinal genetic variation in cold hardiness and leaf phenology, we planted a common garden of paired collections of native and introduced riparian trees sampled along a latitudinal gradient. The garden in Fort Collins, Colorado (latitude 40.6°N), included 681 native plains cottonwood (Populus deltoides subsp. monilifera) and introduced saltcedar (Tamarix ramosissima, T. chinensis, and hybrids) collected from 15 sites from 29.2 to 47.6°N in the central United States. In the common garden, both species showed latitudinal variation in fall, but not spring, leaf phenology. This suggests that latitudinal gradient field observations in fall phenology are a result, at least in part, of the inherited variation in the critical photoperiod. Conversely, the latitudinal gradient field observations in spring phenology are largely a plastic response to the temperature gradient. Populations from higher latitudes exhibited earlier bud set and leaf senescence. Cold hardiness varied latitudinally in both fall and spring for both species. Although cottonwood was hardier than saltcedar in midwinter, the reverse was true in late fall and early spring. The latitudinal variation in fall phenology and cold hardiness of saltcedar appears to have developed as a result of multiple introductions of genetically distinct populations, hybridization, and natural selection in the 150 years since introduction.

Carbon dioxide (CO 2 ), methane (CH 4 ) and nitrous oxide (N 2 O) concentration, saturation and fluxes in rivers (Beitang drainage river, Dagu drainage rive, Duliujianhe river, Yongdingxinhe river and Nanyunhe river) of Tianjin city (Haihe watershed) were investigated during July and October in 2014, and January and April in 2015 by static headspace gas chromatography method and the two-layer model of diffusive gas exchange. The influence of environmental variables on greenhouse gases (GHGs) concentration under the disturbance of anthropogenic activities was discussed by Spearman correlative analysis and multiple stepwise regression analysis. The results showed that the concentration and fluxes of CO 2 , CH 4 and N 2 O were seasonally variable with >winter>fall>summer, spring>summer>winter>fall and summer>spring>winter>fall for concentrations and spring>summer>fall>winter, spring>summer>winter>fall and summer>spring>fall>winter for fluxes respectively. The GHGs concentration and saturation were higher in comprehensively polluted river sites and lower in lightly polluted river sites. The three GHGs emission fluxes in two sewage draining rivers of Tianjin were clearly higher than those of other rivers (natural rivers) and the spatial variation of CH 4 was more obvious than the others. CO 2 and N 2 O air-water interface emission fluxes of the sewage draining rivers in four seasons were about 1.20-2.41 times and 1.13-3.12 times of those in the natural rivers. The CH 4 emission fluxes of the sewage draining rivers were 3.09 times in fall to 10.87 times in spring of those in the natural rivers in different season. The wind speed, water temperature and air temperature were related to GHGs concentrations. Nitrate and nitrite (NO 3 - +NO 2 - -N) and ammonia (NH 4 + -N) were positively correlated with CO 2 concentration and CH 4 concentration; and dissolved oxygen (DO) concentration was negatively correlated with CH 4 concentration and N 2 O concentration. The effect of human activities on carbon and nitrogen cycling in river is great. Copyright © 2017 Elsevier B.V. All rights reserved.

The Pre-Instructors in Math and Science (PIMAS) Program at the University of Arizona's Flandrau Science Center offers high school students the opportunity to explore careers in science teaching through on-the-job training in informal science teaching, both at Flandrau and in the community. The goal of the PIMAS program is to encourage these students to consider pursuing science teaching careers as they transition from high school to college. Students become members of the Flandrau Science Center staff, learning how to present several astronomy demonstrations. These demonstrations include: A Journey to Pluto, Robots on Mars, and Constructing the Seasons. Students also learn how to host star parties. They then offer these presentations at Flandrau on Saturdays and public viewing nights. During the Fall semester, students have the opportunity to learn about best practices in informal science education. They participate, as peers, in the U of A's Science Teachers Colloquium Series. They meet with astronomers, planetary scientists, engineers, and amateur astronomers to learn more about the science behind the demonstrations they are learning. In the Spring semester, students take what they've learned "on the road." They plan and execute Space Nights for their communities-at their schools, their siblings' schools, their churches, their scouting troupes, etc. We believe that by letting the students go into their own communities, they have a greater sense of ownership and pride in these events. The PIMAS Program is now entering its third year. We present both our successes and our lessons learned, as well as what the PIMAS students have to say about the program. We greatly appreciate, and acknowledge, the support of the Arizona Teacher Education Coalition, which is funded by the US Department of Education.

The Arecibo Observatory Space Academy (AOSA) is a ten (10) week pre-college research program for students in grades 9-12. Our mission is to prepare students for academic and professional careers by allowing them to receive an independent and collaborative research experience on topics related to space and aide in their individual academic and social development. Our objectives are to (1) Supplement the student’s STEM education via inquiry-based learning and indirect teaching methods, (2) Immerse students in an ESL environment, further developing their verbal and written presentation skills, and (3) To foster in every student an interest in science by exploiting their natural curiosity and knowledge in order to further develop their critical thinking and investigation skills. AOSA provides students with the opportunity to share lectures with Arecibo Observatory staff, who have expertise in various STEM fields. Each Fall and Spring semester, selected high school students, or Cadets, from all over Puerto Rico participate in this Saturday academy where they receive experience designing, proposing, and carrying out research projects related to space exploration, focusing on four fields: Physics/Astronomy, Biology, Engineering, and Sociology. Cadets get the opportunity to explore their topic of choice while practicing many of the foundations of scientific research with the goal of designing a space settlement, which they present at the NSS-NASA Ames Space Settlement Design Contest. At the end of each semester students present their research to their peers, program mentors, and Arecibo Observatory staff. Funding for this program is provided by NASA SSERVI-LPI: Center for Lunar Science and Exploration with partial support from the Angel Ramos Visitor Center through UMET and management by USRA.

Quality professional development for secondary science teachers

NASA Astrophysics Data System (ADS)

Mchazlett, Dwight Henry, Jr.

This record of study (ROS) explores the perceptions of three high school biology teachers who implemented a form of the Japanese originated Lesson Study Professional Development (LS PD) model. Additionally, this ROS reports on the perceptions of the internal stakeholders with regard to the model's viability as a potential solution to a proposed problem of practice where there was a lack of quality professional development for secondary biology teachers. The audience of internal stakeholders includes district administrators, high school teachers, and science teachers from the elementary and middle school grade levels. Participants of this study collaboratively explored the problem of practice in the fall semester of 2015, then implemented the LS PD model in the spring semester. The participants completed three cycles of LS that focused on collaboratively designing research-based lessons, teaching the lessons with peer observations, revising and re-teaching the lessons with peer observations, and reflecting on the participants' growth experiences. Four research questions were addressed: (a) What are the perceptions of the participants in regard to their own professional growth as a result of participating in the LS initiative? (b) What improvements to the LS PD model might facilitate future implementation? and (c) What are the perceptions of the LS dissemination audience toward LS as a viable solution to a lack of quality PD for secondary biology teachers? Results of the study suggested that LS PD may be a viable solution to the proposed problem of practice where there is a lack of quality professional development for secondary biology teachers. Long-term implications posit that LS PD can be adapted and scaled up to benefit all content areas and grade levels.

Underserved populations in science education: Enhancement through learning community participation

NASA Astrophysics Data System (ADS)

Gray, Jennifer Emily

A positive relationship between college anatomy students' achievement and academic language proficiency in the context of a learning community was established. For many students the barrier to learning science is language. A relationship exists between low academic language proficiency and lack of success among students, in particular failure among at-risk minority and language-minority students. The sample consisted of Anatomy classes during the Fall semesters of the academic years, 2000, 2001, and 2002 at a community college in Central California having a high percentage of culturally and linguistically diverse students. Students from each semester participated in the academic language proficiency and science achievement studies. Twenty-two of the Fall 2002 students (n = 65) enrolled in the Learning Community (LC) that included instruction in academic language in the context of the anatomy course content. Fall 2002 students (n = 19) also participated in Peer-led Support (PLS) sessions. Fall 2001 students participated in a textbook use study (n = 44) and in a Cooperative-Learning (CL) (n = 35) study. Students in the LC and Non-LC groups took the academic language assessment; their results were correlated with course grades and attendance. Fall 2002 students were compared for: (1) differences regarding self-expectations, (2) program impressions, and (3) demographics. Fall 2001 student reading habits and CL participation were analyzed. Results identified: (1) selected academic language tasks as good predictors of science success, (2) a significant positive relationship between science success and participation in support interventions, (3) no differences in self expectations or demographic characteristics of participants and non-participants in the LC group, and (4) poor textbook reading habits. Results showed a significant positive relationship between academic language proficiency and science achievement in participatory instruction.

The practice of learning physics contributes to the development of many transdisciplinary skills learners are able to exercise independent of the physics discipline. However, the standard practices of physics instruction do not explicitly include the monitoring or evaluation of these skills. In a competency-based (CB) learning model, the skills (competencies) are clearly defined and evaluated. We envisioned that a CB approach, where the underlying competencies are highlighted within the instructional process, would be more suitable to teaching physics to learners with diversified disciplinary interests. A model CB course curriculum was developed and practiced at Purdue University to teach introductory college physics to learners who were majoring in the technology disciplines. The experiment took place from the spring semester in 2015 until the spring semester in 2017. The practice provided a means to monitor and evaluate a set of developmental transdisciplinary competencies that underlie the learning of force and motion concepts in classical physics. Additionally, the CB practice contributed to produce substantial physics learning outcomes among learners who were underprepared to learn physics in college.

1998-03-01

In Spring 1996, a one semester course - "Survey of Physics" - was taught for students majoring in Occupational Therapy (O. T.), in contrast to the two semester physics sequence for all other health science majors. The course was designed to expose the students to the concept of physics, develop problem solving skills and to emphasize the importance of physics to O.T. In developing the course content, students' preparedness in mathematics and the perceived future applications of physics in O. T. was taken in to consideration, and steps were taken to remedy the deficiencies in students' background. The course was comprised of lecture, laboratory, and considerable self study due to the time constraints, and these will be described.

Precipitation causes several short- and long-term effects on wind-induced surface erodibility and subsequent dust emission. Among the principal effects considered by this paper are soil moisture, soil crusts, and vegetation. A quantitative method is developed to assess these effects using differences between the potential and the actual amounts of dust emitted from dust sources as inferred from surface meteorological measurements obtained downwind from those sources. The results of this assessment must be interpreted with caution, however, when the size and location of dust sources are unknown. Using meteorological data recorded near Yuma, Arizona at the Yuma Marine Corps Air Station (YMCAS), the method is applied to calculate the potential and actual amounts of dust emitted from upwind dust sources during the spring and fall/winter seasons between January 1, 1981 and May 31, 1988. (Spring is considered to be the period between February 1 and May 31; fall/winter, between October 1 and January 31.) Because summer precipitation is intermittent and wind patterns are localized, summer meteorological data are not used to evaluate regional correlations between precipitation and dust storms. For the period between 1981 and 1988, a correlation of -0.60 was found between fall/winter precipitation and the actual amount of dust emitted from sources upwind of YMCAS during the following spring. A particularly strong reduction in dust emission was noted during the springs of 1983 and 1984 following the start of an 'El Nino event' in fall/winter 1982. Photographs taken at a geological and meteorological data-collection (Geomet) site, located in the natural desert 25 km southeast of YMCAS, show a correspondence between increased antecedent precipitation recorded at the site and increased vegetation. Whereas the annual precipitation totals at YMCAS and the Geomet site from the beginning of 1982 through 1984 are high, their seasonal totals, especially during the fall/winter seasons, are disparate. This fall/winter precipitation disparity may account for evidence suggesting that significant vegetation growth occurred at dust sources upwind of YMCAS by spring 1983, but that such growth did not occur at the Geomet site until fall/ winter of 1983. Spatial inhomogeneity in fall/winter precipitation probably contributed to the relatively low correlation (-0.60) between fall/winter precipitation recorded at YMCAS and the actual amount of dust emitted from upwind sources during the following spring. ?? 1990 Kluwer Academic Publishers.

Mediterranean climate patterns and wine quality in North and Central Italy.

Results show that the year-to-year quality variation of wines produced in North and Central Italy depends on the large-scale climate variability, and that the wine quality improvement in the last four decades is partially due to an increase of temperature and to a decrease of precipitation in West and Central Mediterranean Europe (WME; CME). In addition, wine quality is positively correlated with air temperature throughout the entire active period of the grapevine, weakly negatively correlated with precipitation in spring, and well negatively correlated in summer and fall. The month-to-month composites of the NAO anomaly show that, in years of good quality wine, this anomaly is negative in late spring, oscillates around zero in summer, and is positive in early fall; while, in years of bad quality wine, it is positive in late spring and summer, and negative in early fall, i.e. its polarity has an opposite sign in spring and fall in good versus bad years. The composite seasonal maps show that good wines are produced when the spring jet stream over the Atlantic diverts most of the weather perturbations towards North Europe, still providing a sufficient amount of rainwater to CME; when summer warming induced by southerly winds is balanced by the cooling induced by westerly winds; and when a positive geopotential anomaly over WME shelters CME from fall Atlantic storms. Bad quality wines are produced when the jet stream favors the intrusion of the Atlantic weather perturbations into the Mediterranean. Results suggest that atmospheric pattern persistencies can be used as precursors for wine quality forecast.

Developmental and environmental effects on assimilate partitioning in Canada thistle

1989-04-01

Canada thistle (Cirsium arvense) plants at three stages of development (rosette, bolt, and flower bud) were grown under spring-simulated or fall-simulated environments. Sucrose export from a single leaf exposed to {sup 14}CO{sub 2} was significantly greater in rosette-plants than bolt- or flower bud-plants during the first two hours after pulse. Twenty-four hours after pulse, total {sup 14}C translocation (dpm) was the same in both environments but the {sup 14}C concentration (dpm/gm) was greater in roots of fall-grown plants. Shoot meristem respiration of fall-grown plants was approximately 50% less than spring-grown plants and was a factor responsible for this trend. Concentrationsmore » of inulin and water-insoluble starch were greater in roots of fall-grown than spring-grown plants and pulsed {sup 14}C accumulated in these fractions. The results suggest that a shift in respiration and metabolism of fall-grown rosette- and bolt-plants leads to increased assimilate movement to the root which may have practical implications for control of this weed.« less

Wave energetics of the southern hemisphere of Mars

NASA Astrophysics Data System (ADS)

Battalio, Michael; Szunyogh, Istvan; Lemmon, Mark

2018-07-01

An assessment of the energetics of transient waves in the southern hemisphere of Mars is presented using the Mars Analysis Correction Data Assimilation (MACDA) dataset (v1.0) and the eddy kinetic energy equation. The dataset is divided into four representative periods covering the summer and winter solstices, a late fall period, and an early spring period for three Mars years. Spring eddies are the most intense, with eddies during the fall being less intense due to a marginally more stable mean-temperature profile and reduced recirculation of ageostrophic geopotential fluxes compared to the spring. Eddy kinetic energy during winter is reduced in intensity as a result of the winter solstitial pause in wave activity, and eddy kinetic energy during the summer is limited. Baroclinic energy conversion acts as a source in fall and spring but disappears during the winter as a result of a stabilized vertical temperature profile. Barotropic energy conversion acts as both a source and a sink of eddy kinetic energy, being most positive during the solstitial pause. Eddies take a northwest to southeast track across the southern highlands in the fall but have a more zonal track in the spring due to stronger eddy kinetic energy advection. Wave energetics is less intense in the southern compared to the northern hemisphere as a result of a shallower baroclinically unstable vertical profile.

Theory indicates that landscape composition affects transmission of vector-borne crop diseases, but few empirical studies have investigated how landscape composition affects plant disease epidemiology. Since 2006, Bemisia tabaci (Gennadius) has vectored the cucurbit yellow stunting disorder virus (CYSDV) to cantaloupe and honeydew melons (Cucumis melo L.) in the southwestern United States and northern Mexico, causing significant reductions in yield of fall melons and increased use of insecticides. Here, we show that a landscape-based approach allowing simultaneous assessment of impacts of local (i.e., planting date) and regional (i.e., landscape composition) factors provides valuable insights on how to reduce crop disease risks. Specifically, we found that planting fall melon fields early in the growing season, eliminating plants germinating from seeds produced by spring melons after harvest, and planting fall melon fields away from cotton and spring melon fields may significantly reduce the incidence of CYSDV infection in fall melons. Because the largest scale of significance of the positive association between abundance of cotton and spring melon fields and CYSDV incidence was 1,750 and 3,000 m, respectively, reducing areas of cotton and spring melon fields within these distances from fall melon fields may decrease CYSDV incidence. Our results indicate that landscape-based studies will be fruitful to alleviate limitations imposed on crop production by vector-borne diseases.

Summers on the Colorado Plateau (USA) are typified by harsh conditions such as high temperatures, brief soil hydration periods, and high UV and visible radiation. We investigated whether community composition, physiological status, and pigmentation might vary in biological soil crusts as a result of such conditions. Representative surface cores were sampled at the ENE, WSW, and top microaspects of 20 individual soil crust pedicels at a single site in Canyonlands National Park, Utah, in spring and fall of 1999. Frequency of cyanobacterial taxa, pigment concentrations, and dark adapted quantum yield (Fv/Fm) were measured for each core. The frequency of major cyanobacterial taxa was lower in the fall compared to spring. The less-pigmented cyanobacterium Microcoleus vaginatus showed significant mortality when not in the presence of Nostoc spp. and Scytonema myochrous (Dillw.) Agardh. (both synthesizers of UV radiation-linked pigments) but had little or no mortality when these species were abundant. We hypothesize that the sunscreen pigments produced by Nostoc and Scytonema in the surface of crusts protect other, less-pigmented taxa. When fall and spring samples were compared, overall cyanobacterial frequency was lower in fall, while sunscreen pigment concentrations, chlorophyll a concentration, and Fv/Fm were higher in fall. The ratio of cyanobacterial frequency/chlorophyll a concentrations was 2-3 times lower in fall than spring. Because chlorophyll a is commonly used as a surrogate measure of soil cyanobacterial biomass, these results indicate that seasonality needs to be taken into consideration. In the fall sample, most pigments associated with UV radiation protection or repair were at their highest concentrations on pedicel tops and WSW microaspects, and at their lowest concentrations on ENE microaspects. We suggest that differential pigment concentrations between microaspects are induced by varying UV radiation dosage at the soil surface on these different microaspects.

Teacher organization is a crucial part of classroom functioning; however, its relation to student achievement has not been investigated as extensively as that of instruction. In this study, organization is defined as the amount of time teachers spend explaining the purpose and procedures of learning activities and daily routines. Data from first-grade classrooms (N=44) observed three times during the school year (fall, winter, and spring) are analyzed, along with students' (N=108) literacy skills at fall and spring. Hierarchical Linear Modeling reveals that, controlling for students' fall word reading and vocabulary skills, as well as amount of language arts instruction they receive, both amount and change in amount over time in classroom organization significantly predicts spring word reading skills. Specifically, children in classrooms observed in higher amounts of classroom time in organization at the beginning of the school year, followed by sharp decreases over the school year, demonstrated stronger letter and word reading skills by spring, and this was a main effect (p<.05). Practical and research implications are discussed.

Five-year growth trajectories of kindergarten children with learning difficulties in mathematics.

Morgan, Paul L; Farkas, George; Qiong Wu

2009-01-01

The investigators used data from the Early Childhood Longitudinal Study-Kindergarten Cohort (ECLS-K) to estimate whether and to what extent the timing and persistence of mathematics difficulties (MD) in kindergarten predicted children's first through fifth grade math growth trajectories. Results indicated that children persistently displaying MD (i.e., those experiencing MD in both fall and spring of kindergarten) had the lowest subsequent growth rates, children with MD in spring only had the second-lowest growth rates, and children with MD in the fall only (and who had thus recovered from their MD by the spring of kindergarten) had the next-lowest growth rates. The children who did not have MD in either fall or spring of kindergarten had the highest growth rates. These results were observed prior to and after statistical control for additional variables. They indicate that measuring the timing and persistence of kindergarten children's mathematics learning difficulties may help identify those most at risk for failing to become mathematically proficient during elementary school.

Trends in timing, magnitude, and duration of summer and fall/winter streamflows for unregulated coastal river basins in Maine during the 20th century

USGS Publications Warehouse

Dudley, Robert W.; Hodgkins, Glenn A.

2005-01-01

The U.S. Geological Survey (USGS), in cooperation with the Maine Atlantic Salmon Commission (ASC), began a study in 2003 to examine the timing, magnitude, and duration of summer (June through October) and fall/early winter (September through January) seasonal streamflows of unregulated coastal river basins in Maine and to correlate them to meteorological variables and winter/spring (January through May) seasonal streamflows. This study overlapped the summer seasonal window with the fall/early winter seasonal window to completely bracket the low-streamflow period during July, August, and September between periods of high streamflows in June and October. The ASC is concerned with the impacts of potentially changing meteorological and hydrologic conditions on Atlantic salmon survival. Because winter/spring high streamflows appear to have trended toward earlier dates over the 20th century in coastal Maine, it was hypothesized that the spring/summer recession to low streamflows could have a similar trend toward earlier, and possibly lower, longer lasting, late summer/early fall low streamflows during the 20th century. There were few statistically significant trends in the timing, magnitude, or duration of summer low streamflows for coastal river basins in Maine during the 20th century. The hypothesis that earlier winter/spring high streamflows may result in earlier or lower low streamflows is not supported by the data. No statistically significant trends in the magnitude of total runoff volume during the low-streamflow months of August and September were observed. The magnitude and timing of summer low streamflows correlated with the timing of fall/winter high streamflows and the amount of summer precipitation. The magnitude and timing of summer low streamflows did not correlate with the timing of spring snowmelt runoff. There were few correlations between the magnitude and timing of summer low streamflows and monthly mean surface air temperatures. There were few statistically significant trends in the timing or duration of fall/winter high streamflows for coastal river basins in Maine during the 20th century. The timing of the bulk of fall/winter high streamflows correlated with seasonal precipitation. Earlier fall/winter center-of-volume dates correlated with higher September and October precipitation. In general, little evidence was observed of trends in the magnitude of seasonal runoff volume during fall/winter. The magnitude of fall/winter high streamflows positively correlated with November and December precipitation amounts. There were few correlations between the magnitude and timing of fall/winter high streamflows and monthly mean surface air temperatures.

The Education and Public Outreach Group (EPO) group of the National Optical Astronomy Observatory has started a partnership with Indian Oasis Baboquivari Unified School District (IOBUSD) on the Tohono O'odham Nation to participate in after school science education programs. IOBUSD has started an after school program for K-5 students as part of their state mandated school improvement program. The first semester has approximately 50 students in K-5 participating in the after school program from Monday through Thursday. Several organizations are working with IOBUSD to provide after school educational programs focusing on a variety of topics including study skills, art, nutrition, bullying, study skills and science. NOAO has been working primarily with the fourth and fifth grade students during the spring of 2012 once a week providing science programs in optics, dark skies and astronomy. We are currently planning to continue this partnership in the fall of 2012 when the school district is planning to invite more students to join the program. We will discuss many the challenges of working with a school district in a remote location as well as the activities we have been using with the students. We will also outline plans for future directions in the program.

Heavy Alcohol Use and Dating Violence Perpetration During Adolescence: Family, Peer and Neighborhood Violence as Moderators

Foshee, Vangie A.; Bauer, Daniel J.; Ennett, Susan T.

2014-01-01

We examined the hypothesis that family, peer and neighborhood violence would moderate relations between heavy alcohol use and adolescent dating violence perpetration such that relations would be stronger for teens in violent contexts. Random coefficients growth models were used to examine the main and interaction effects of heavy alcohol use and four measures of violence (family violence, friend dating violence, friend peer violence and neighborhood violence) on levels of physical dating violence perpetration across grades 8 through 12. The effects of heavy alcohol use on dating violence tended to diminish over time and were stronger in the spring than in the fall semesters. Consistent with hypotheses, across all grades, relations between heavy alcohol use and dating violence were stronger for teens exposed to higher levels of family violence and friend dating violence. However, neither friend peer violence nor neighborhood violence moderated relations between alcohol use and dating violence. Taken together, findings suggest that as adolescents grow older, individual and contextual moderators may play an increasingly important role in explaining individual differences in relations between alcohol use and dating violence. Implications for the design and evaluation of dating abuse prevention programs are discussed. PMID:21494801

2010-01-01

There is widespread agreement within the scientific and education communities that undergraduate biology curricula fall short in providing students with the quantitative and interdisciplinary problem-solving skills they need to obtain a deep understanding of biological phenomena and be prepared fully to contribute to future scientific inquiry. MathBench Biology Modules were designed to address these needs through a series of interactive, Web-based modules that can be used to supplement existing course content across the biological sciences curriculum. The effect of the modules was assessed in an introductory biology course at the University of Maryland. Over the course of the semester, students showed significant increases in quantitative skills that were independent of previous math course work. Students also showed increased comfort with solving quantitative problems, whether or not they ultimately arrived at the correct answer. A survey of spring 2009 graduates indicated that those who had experienced MathBench in their course work had a greater appreciation for the role of mathematics in modern biology than those who had not used MathBench. MathBench modules allow students from diverse educational backgrounds to hone their quantitative skills, preparing them for more complex mathematical approaches in upper-division courses.

Near-peer teaching (NPT) is a strategy in which senior students assume the instructor role with junior peers (mentees). Senior students develop unique skills and knowledge through NPT, an experience which extends their learning beyond content mastery. Different teaching modules featuring NPT were utilized in the human anatomy course at the School of Medicine, Autonomous University of Nuevo Leon in Monterrey, Mexico. Modules included: Theory, Clinical Hour, Imaging Anatomy, and Laboratory. The aim of this study was to assess instructor participants' perceptions on the benefits of the NPT strategy in the anatomy classroom. A survey was administered to anatomy course instructors who utilized NPT strategies during winter, fall, and spring semesters of the 2012-2013 school year. A total of 120 instructors were enrolled in the study. There were different perceptions of instructors' roles. Theory and Imaging Anatomy instructors considered themselves to be information providers and resource developers, whereas Clinical Hour and Laboratory instructors saw themselves more as facilitators, role models, and planners. All instructors' opinions on the benefits of NPT were positive. Thus, in this article, the authors find NPT to be a strategy that promotes self-learning, a vital skill. © 2014 American Association of Anatomists.

Socialization of new dental therapists on entering the profession.

Lopez, Naty; Blue, Christine M

2011-05-01

Dental therapy is relatively new in the United States. This qualitative study examines the experiences and impressions of the inaugural class of the first dental school-based dental therapy program in the United States. A grounded theory design using open-ended interviews and focus groups was carried out with the nine students in the class at the beginning of their program and after the fall and spring semesters of their first year. Student responses were audiotaped, transcribed verbatim, and presented to the students for feedback and clarification. Results show that students started with an idealistic perception of dental therapy that was consistent with the specific provision of the law creating dental therapy. The team learning approach in which dental therapy students learn alongside dental and dental hygiene students provided the social interaction that allowed them to better articulate and distinguish dental therapy from those other dental professions. In the absence of dental therapists who could serve as role models, the program director, who is perceived to be the dental therapy expert, has assumed the role of the primary socializer. Faculty members are challenged to fulfill their role as role models regardless of their perception of the dental therapy model.

Prevatte, Scott A.

2006-03-01

In the fall of 2004, as one part of a Basin-Wide Monitoring Program developed by the Upper Columbia Regional Technical Team and Upper Columbia Salmon Recovery Board, the Yakama Nation Fisheries Resource Management program began monitoring downstream migration of ESA listed Upper Columbia River spring chinook salmon and Upper Columbia River steelhead in Nason Creek, a tributary to the Wenatchee River. This report summarizes juvenile spring chinook salmon and steelhead trout migration data collected in Nason Creek during 2005 and also incorporates data from 2004. We used species enumeration at the trap and efficiency trials to describe emigration timing andmore » to estimate population size. Data collection was divided into spring/early summer and fall periods with a break during the summer months occurring due to low stream flow. Trapping began on March 1st and was suspended on July 29th when stream flow dropped below the minimum (30 cfs) required to rotate the trap cone. The fall period began on September 28th with increased stream flow and ended on November 23rd when snow and ice began to accumulate on the trap. During the spring and early summer we collected 311 yearling (2003 brood) spring chinook salmon, 86 wild steelhead smolts and 453 steelhead parr. Spring chinook (2004 brood) outgrew the fry stage of fork length < 60 mm during June and July, 224 were collected at the trap. Mark-recapture trap efficiency trials were performed over a range of stream discharge stages whenever ample numbers of fish were being collected. A total of 247 spring chinook yearlings, 54 steelhead smolts, and 178 steelhead parr were used during efficiency trials. A statically significant relationship between stream discharge and trap efficiency has not been identified in Nason Creek, therefore a pooled trap efficiency was used to estimate the population size of both spring chinook (14.98%) and steelhead smolts (12.96%). We estimate that 2,076 ({+-} 119 95%CI) yearling spring chinook and 688 ({+-} 140 95%CI) steelhead smolts emigrated past the trap during the spring/early summer sample period along with 10,721 ({+-} 1,220 95%CI) steelhead parr. During the fall we collected 924 subyearling (2004 brood) spring chinook salmon and 1,008 steelhead parr of various size and age classes. A total of 732 spring chinook subyearlings and 602 steelhead parr were used during 13 mark-recapture trap efficiency trials. A pooled trap efficiency of 24.59% was used to calculate the emigration of spring chinook and 17.11% was used for steelhead parr during the period from September 28th through November 23rd. We estimate that 3758 ({+-} 92 95%CI) subyearling spring chinook and 5,666 ({+-} 414 95%CI) steelhead parr migrated downstream past the trap along with 516 ({+-} 42 95%CI) larger steelhead pre-smolts during the 2005 fall sample period.« less

Changes in seasonality and timing of peak streamflow in snow and semi-arid climates of the north-central United States, 1910–2012

USGS Publications Warehouse

Ryberg, Karen R.; Akyüz, F. Adnan; Wiche, Gregg J.; Lin, Wei

2015-01-01

Changes in the seasonality and timing of annual peak streamflow in the north-central USA are likely because of changes in precipitation and temperature regimes. A source of long-term information about flood events across the study area is the U.S. Geological Survey peak streamflow database. However, one challenge of answering climate-related questions with this dataset is that even in snowmelt-dominated areas, it is a mixed population of snowmelt/spring rain generated peaks and summer/fall rain generated peaks. Therefore, a process was developed to divide the annual peaks into two populations, or seasons, snowmelt/spring, and summer/fall. The two series were then tested for the hypotheses that because of changes in precipitation regimes, the odds of summer/fall peaks have increased and, because of temperature changes, snowmelt/spring peaks happen earlier. Over climatologically and geographically similar regions in the north-central USA, logistic regression was used to model the odds of getting a summer/fall peak. When controlling for antecedent wet and dry conditions and geographical differences, the odds of summer/fall peaks occurring have increased across the study area. With respect to timing within the seasons, trend analysis showed that in northern portions of the study region, snowmelt/spring peaks are occurring earlier. The timing of snowmelt/spring peaks in three regions in the northern part of the study area is earlier by 8.7– 14.3 days. These changes have implications for water interests, such as potential changes in lead-time for flood forecasting or changes in the operation of flood-control dams.

Six months of disuse during hibernation does not increase intracortical porosity or decrease cortical bone geometry, strength, or mineralization in black bear (Ursus americanus) femurs

PubMed Central

McGee-Lawrence, Meghan E.; Wojda, Samantha J.; Barlow, Lindsay N.; Drummer, Thomas D.; Bunnell, Kevin; Auger, Janene; Black, Hal L.; Donahue, Seth W.

2009-01-01

Disuse typically uncouples bone formation from resorption, leading to bone loss which compromises bone mechanical properties and increases the risk of bone fracture. Previous studies suggest that bears can prevent bone loss during long periods of disuse (hibernation), but small sample sizes have limited the conclusions that can be drawn regarding the effects of hibernation on bone structure and strength in bears. Here we quantified the effects of hibernation on structural, mineral, and mechanical properties of black bear (Ursus americanus) cortical bone by studying femurs from large groups of male and female bears (with wide age ranges) killed during pre-hibernation (fall) and post-hibernation (spring) periods. Bone properties that are affected by body mass (e.g. bone geometrical properties) tended to be larger in male compared to female bears. There were no differences (p > 0.226) in bone structure, mineral content, or mechanical properties between fall and spring bears. Bone geometrical properties differed by less than 5% and bone mechanical properties differed by less than 10% between fall and spring bears. Porosity (fall: 5.5 ± 2.2%, spring: 4.8 ± 1.6%) and ash fraction (fall: 0.694 ± 0.011, spring: 0.696 ± 0.010) also showed no change (p > 0.304) between seasons. Statistical power was high (>72%) for these analyses. Furthermore, bone geometrical properties and ash fraction (a measure of mineral content) increased with age and porosity decreased with age. These results support the idea that bears possess a biological mechanism to prevent disuse and age-related osteoporoses. PMID:19450804

Annual and Spatial Variation of the Kelp Forest Fish Assemblage at San Nicolas Island, California

Cowen, R.J.; Bodkin, James L.

1993-01-01

The kelp forest fishes of San Nicolas Island, California were studied from 1981-1986 to examine the causes of among-site and among-year variation in the fish assemblages. Fish counts and seven physical and biological variables were recorded at six sites around the island every spring and fall. Over the study period, a total of 45 fish species from 18 families were recorded, though members of nive families dominated at all sites. Among-site variation was considereable with two sites on the south side of the island having two to four times as many non-schooling fishes as the other four sites. Three variables, based on stepwise multiple regression techniques, were important predictors of site-specific fish abundance: 1) vertical relief; 2) sand cover and 3) understory algal cover. The total number of fishes varied interannually by a factor of three. Due to recruitment occuring each spring, there was a strong seasonal component to the variation in fish abundance. The extent of seasonal and interannual variaton of fish abundance is an indication of the variable nature of recruitment to this area. Over the 6 yr period, there were three distinct groupings of fish assemblages correspondong to pre- (Fall 1981 - Fall 1982), during spring (Spring 1983 - Spring 1984) and post El Nino (Fall 1984 - Fall 1986) sampling dates. During El Nino sampling period, there was considerable recruitment of southern affinity fish species, increasing both the abundance and diversity of the fish assemblages. Large-scale oceanographic processes, coupled with site-specific features of the reef habitat, produce a moderately diverse, though relatively abundant fish fauna at San Nicolas Island.

Educators' emotion regulation strategies and their physiological indicators of chronic stress over 1 year.

Studies show teaching is a highly stressful profession and that chronic work stress is associated with adverse health outcomes. This study analysed physiological markers of stress and self-reported emotion regulation strategies in a group of middle school teachers over 1 year. Chronic physiological stress was assessed with diurnal cortisol measures at three time points over 1 year (fall, spring, fall). The aim of this longitudinal study was to investigate the changes in educators' physiological level of stress. Results indicate that compared to those in the fall, cortisol awakening responses were blunted in the spring. Further, this effect was ameliorated by the summer break. Additionally, self-reported use of the emotion regulation strategy reappraisal buffered the observed blunting that occurred in the spring. Copyright © 2017 John Wiley & Sons, Ltd.

Cognitive variables included second semester general chemistry grade, ACT composite score, ACT English, mathematics, reading, and science reasoning subscores, and spatial ability. Non-cognitive variables included anxiety, confidence, effectance motivation, and usefulness. Using a correlation research design, the individual relationships between organic chemistry achievement and each of the cognitive variables and non-cognitive variables were assessed. In addition, the relationships between organic chemistry achievement and combinations of these independent variables were explored. Finally, gender- and instructor-related differences in the relationships between organic chemistry achievement and the independent variables were investigated. The samples consisted of volunteers from the Fall 1999 and Fall 2000 sections of Organic Chemistry I at the University of Arkansas. All students in each section were asked to participate. Data for spatial ability and non-cognitive independent variables were collected using the Purdue Visualization of Rotations test and the modified Fennema-Sherman Attitude Scales. Data for other independent variables, including ACT scores and second semester general chemistry grades, were obtained from the Office of Institutional Research. The dependent variable, organic chemistry achievement, was measured by each student's accumulated points in the course and consisted of scores on quizzes and exams in the lecture section only. These totals were obtained from the lecture instructor at the end of each semester. Pearson correlation and stepwise multiple regression analyses were used to measure the relationships between organic chemistry achievement and the independent variables. Prior performance in chemistry as measured by second semester general chemistry grade was the best indicator of performance in organic chemistry. The importance of other independent variables in explaining organic chemistry achievement varied between instructors. In addition, gender differences were found in the explanations of organic chemistry achievement variance provided by this study. In general, males exhibited stronger correlations between independent variables and organic chemistry achievement than females. The report contains 19 tables detailing the statistical analyses. Suggestions for improved practice and further research are also included

Divergent responses to spring and winter warming drive community level flowering trends

PubMed Central

Cook, Benjamin I.; Wolkovich, Elizabeth M.; Parmesan, Camille

2012-01-01

Analyses of datasets throughout the temperate midlatitude regions show a widespread tendency for species to advance their springtime phenology, consistent with warming trends over the past 20–50 y. Within these general trends toward earlier spring, however, are species that either have insignificant trends or have delayed their timing. Various explanations have been offered to explain this apparent nonresponsiveness to warming, including the influence of other abiotic cues (e.g., photoperiod) or reductions in fall/winter chilling (vernalization). Few studies, however, have explicitly attributed the historical trends of nonresponding species to any specific factor. Here, we analyzed long-term data on phenology and seasonal temperatures from 490 species on two continents and demonstrate that (i) apparent nonresponders are indeed responding to warming, but their responses to fall/winter and spring warming are opposite in sign and of similar magnitude; (ii) observed trends in first flowering date depend strongly on the magnitude of a given species’ response to fall/winter vs. spring warming; and (iii) inclusion of fall/winter temperature cues strongly improves hindcast model predictions of long-term flowering trends compared with models with spring warming only. With a few notable exceptions, climate change research has focused on the overall mean trend toward phenological advance, minimizing discussion of apparently nonresponding species. Our results illuminate an understudied source of complexity in wild species responses and support the need for models incorporating diverse environmental cues to improve predictability of community level responses to anthropogenic climate change.

Daylight savings time and myocardial infarction.

PubMed

Sandhu, Amneet; Seth, Milan; Gurm, Hitinder S

2014-01-01

Prior research has shown a transient increase in the incidence of acute myocardial infarction (AMI) after daylight savings time (DST) in the spring as well as a decrease in AMI after returning to standard time in the fall. These findings have not been verified in a broader population and if extant, may have significant public health and policy implications. We assessed changes in admissions for AMI undergoing percutaneous coronary intervention (PCI) in the Blue Cross Blue Shield of Michigan Cardiovascular Consortium (BMC2) database for the weeks following the four spring and three fall DST changes between March 2010 and September 2013. A negative binomial regression model was used to adjust for trend and seasonal variation. There was no difference in the total weekly number of PCIs performed for AMI for either the fall or spring time changes in the time period analysed. After adjustment for trend and seasonal effects, the Monday following spring time changes was associated with a 24% increase in daily AMI counts (p=0.011), and the Tuesday following fall changes was conversely associated with a 21% reduction (p=0.044). No other weekdays in the weeks following DST changes demonstrated significant associations. In the week following the seasonal time change, DST impacts the timing of presentations for AMI but does not influence the overall incidence of this disease.

Foraging habitat for shorebirds in southeastern Missouri and its predicted future availability

USGS Publications Warehouse

Twedt, Daniel J.

2013-01-01

Water management to protect agriculture in alluvial floodplains often conflicts with wildlife use of seasonal floodwater. Such is the case along the Mississippi River in southeastern Missouri where migrating shorebirds forage in shallow-flooded fields. I estimated the current availability of habitat for foraging shorebirds within the New Madrid and St. Johns Basins based on daily river elevations (1943–2009), under assumptions that shorebirds forage in open habitat with water depth <15 cm and use mudflats for 3 days after exposure. The area of shorebird foraging habitat, based on replicated 50-year random samples, averaged 975 ha per day during spring and 33 ha per day during fall. Adjustments to account for habitat quality associated with different water depths, duration of mudflat exposure, intra-seasonal availability, and state of agricultural crops, indicated the equivalent of 494 ha daily of optimal habitat during spring and 11 ha during fall. Proposed levees and pumps to protect cropland would reduce shorebird foraging habitat by 80 %: to 211 ha (108 optimal ha) per day during spring and 9 ha (<3 optimal ha) per day during fall. Alternative water management that allows natural flooding below a prescribed elevation would retain nearly all existing shorebird foraging habitat during fall and about 60 % of extant habitat during spring.

Many U.S. natural resource agencies stock catfish (Ictaluridae) into small impoundments to provide recreational fishing opportunities. However, effective standardized methods for sampling catfish in small impoundments have not been developed for wide application, particularly in the southeastern United States. We evaluated the efficiency of three bait treatments (i.e., soybean cake, sunflower cake, and no bait) of tandem hoop nets in two North Carolina small impoundments during the fall of 2008 and spring of 2009 in a factorial experimental design. The impoundments were stocked with catchable-size channel catfish Ictalurus punctatus at contrastingly low (5.5 fi sh/ha) and high (90.0 fi sh/ha) rates prior to our sampling. Nets baited with soybean cake consistently sampled more channel catfish than any other treatment. Channel catfish catch ranged as high as 3,251 fi sh per net series during the fall in nets baited with soybean cake in the intensively stocked impoundment and was up to 8.5 and 15.3 times higher during the fall than in the spring in each impoundment. Nets baited with soybean cake sampled significantly (12 and 24 times) more channel catfish than those with no bait in the two impoundments. These trends did not occur among other catfish species. Nonictalurid fish and turtle catch was higher during spring compared to that of fall, corresponding with low channel catfish catches. Our results indicate that tandem hoop nets baited with soybean cake during the fall is a more efficient method for sampling channel catfish compared to nets baited with sunflower cake or no bait in spring or fall. Our findings validate this technique for application in southeastern U.S. small impoundments to assess catfish abundance to guide management and evaluate the success of catfish stocking programs.

2008-12-01

Treated drinking water samples from 12 water utilities in the Midwestern United States were collected during Fall 2003 and Spring 2004 and were analyzed for selected neutral degradates of chloroacetamide herbicides, along with related compounds. Target analytes included 20 neutral chloroacetamide degradates, six ionic chloroacetamide degradates, four parent chloroacetamide herbicides, three triazine herbicides, and two neutral triazine degradates. In the fall samples, 17 of 20 neutral chloroacetamide degradates were detected in the finished drinking water, while 19 of 20 neutral chloroacetamide degradates were detected in the spring. Median concentrations for the neutral chloroacetamide degradates were approximately 2-60ng/L during both sampling periods. Concentrations measured in the fall samples of treated water were nearly the same as those measured in source waters, despite the variety of treatment trains employed. Significant removals (average of 40% for all compounds) were only found in the spring samples at those utilities that employed activated carbon.

Hydrology, water quality, and simulation of ground-water flow at a taconite-tailings basin near Keewatin, Minnesota

Myette, C.F.

1991-01-01

Numerical-model simulations of ground-water flow near the vicinity of the tailings basin indicate that, if areal recharge were doubled during spring and fall, water levels in wells could average about 4 feet above 1983 levels during these periods. Model results indicate that water levels in the tailings could possibly remain about 5 feet above 1983 levels at the end of the year. Water levels in the tailings at the outlet of the basin could be about 1 foot above 1983 levels during the spring stress period and could be nearly 1.5 feet above 1983 levels during the fall stress period. Under these hypothetical climatic conditions, ground-water contribution to discharge at the outlet could be about 50 cubic feet per second during spring and about 80 cubic feet per second during fall.

The Little Wind River drainage in Wyoming is a relatively small unimpounded river system inhabited by native saugers Sander canadensis. Radio telemetry was used to assess habitat use and movement patterns by adult saugers in the river system from fall through early summer. Fifty-four adult saugers were captured during fall 2004, surgically implanted with radio transmitters, and tracked through mid-July 2005. Tagged saugers selected large and deep pools. Such pools were abundant throughout the Little Wind River system and led to saugers being widely dispersed from fall to early spring. During fall, winter, and early spring, tagged saugers remained sedentary and moved short distances among pools in close proximity to each other. Longer movements by tagged saugers occurred from mid-spring to early summer, and were associated with both upstream and downstream movements to and from two river segments believed to be used for spawning. During early summer, most saugers returned to locations where they had been tagged the previous fall and had spent the winter. Our results provide evidence that preservation of the sauger fishery in the Wind River system will depend on maintaining fish passage throughout the portion of the watershed inhabited by saugers and preserving natural fluvial processes that maintain large and deep pools. ??

K-12 teacher professional development rich in content and pedagogical methods and materials for implementation of STEM concepts in the classroom will enhance teacher preparation and practice, and ultimately student learning is the purpose of the American Meteorological Society (AMS) DataStreme Project. DataStreme Atmosphere, Ocean, and Earth's Climate System (ECS) are offered each fall and spring semester by Local Implementation Teams across the country in coordination with AMS Education Program scientists and educators. Participants may receive 3 tuition-free graduate credits through State University of New York's The College at Brockport upon completion of each course and construction of a Plan of Action for peer-training. Peer training is a key focus of DataStreme. Based on survey results, a DataStreme participant impacts an average of up to 10 other teachers and over 350 students within two years of training. Therefore, the 220 teachers who completed a DataStreme course in fall 2015 will likely reach over 2000 teachers and close to 77,000 students within two years. Further, DataStreme improves teachers' pedagogical abilities. According to the fall 2015 pre-survey of DataStreme ECS participants, approximately 15% of participants rated their pedagogical abilities in the Superior or Exemplary levels (highest rankings). On the post-survey, 59% of participants fell in these categories, clearly highlighting the positive shift. This survey also revealed teachers' ability to use climate-science content to stimulate student interests. The AMS looks to further this success with redevelopment of a previously offered K-12 teacher professional development course focused on water. From 2001-2008, AMS offered DataStreme Water in the Earth System, training 3145 teachers on the global water cycle. AMS is eager to continue helping teachers and students improve their understanding of water processes and overall environmental science literacy.

The spatial distribution of nine Northwest Atlantic groundfish stocks was documented using spatial indicators based on Northeast Fisheries Science Center spring and fall bottom trawl survey data, 1963-2016. We then evaluated the relative importance of population size, fishing pressure and bottom temperature on spatial distribution with an information theoretic approach. Northward movement in the spring was generally consistent with prior analyses, whereas changes in depth distribution and area occupancy were not. Only two stocks exhibited the same changes in spatiotemporal distribution in the fall as compared with the spring. Fishing pressure was the most important predictor of the center of gravity (i.e., bivariate mean location of the population) for the majority of stocks in the spring, whereas in the fall this was restricted to the east-west component. Fishing pressure was also the most important predictor of the dispersion around the center of gravity in both spring and fall. In contrast, biomass was the most important predictor of area occupancy for the majority of stocks in both seasons. The relative importance of bottom temperature was ranked highest in the fewest number of cases. This study shows that fishing pressure, in addition to the previously established role of climate, influences the spatial distribution of groundfish in the Northwest Atlantic. More broadly, this study is one of a small but growing body of literature to demonstrate that fishing pressure has an effect on the spatial distribution of marine resources. Future work must consider both fishing pressure and climate when examining mechanisms underlying fish distribution shifts.

Nonpoint-source pollution from agricultural activities is currently the leading cause of degradation of waterways in the United States. Applying best management practices to flood-irrigated mountain meadows may improve agricultural runoff and return flow water quality. Prior research has focused on fertilizer use for increased hay yields, while few studies have investigated the environmental implications of this practice. We examined the effects of fertilizer application timing on overland flow water quality from an irrigated mountain meadow near Gunnison, Colorado. Application of 40 kg phosphorus (P) and 19 kg nitrogen (N) ha(-1) using monoammonium phosphate (11-52-0, N-P-K) fertilizer to plots in the fall significantly reduced concentrations of reactive P and ammonium N in irrigation overland flow compared with early or late spring fertilization. Reactive P loading was 9 to almost 16 times greater when fertilizer was applied in the early or late spring, respectively, compared with in the fall. Ammonium N followed a similar trend with early spring loading more than 18 times greater and late spring loading more than 34 times greater than loads from fall-fertilized plots. Losses of 45% of the applied P and more than 17% of the N were measured in runoff when fertilizer was applied in the late spring. These results, coupled with those from previous studies, suggest that mountain meadow hay producers should apply fertilizer in the fall, especially P-based fertilizers, to improve hay yields, avoid economic losses from loss of applied fertilizers, and reduce the potential for impacts to water quality.

Behavioral thermoregulation by juvenile spring and fall chinook salmon, Oncorhynchus tshawytscha, during smoltification

Fall chinook salmon evolved to emigrate during the summer months. The shift in the temperature preference we observed in smolting fall chinook but not spring chinook salmon may reflect a phylogenetic adaptation to summer emigration by (1) providing directional orientation as fall chinook salmon move into the marine environment, (2) maintaining optimal gill function during emigration and seawater entry, and/or (3) resetting thermoregulatory set-points to support physiological homeostasis once smolted fish enter the marine environment. Phylogenetically determined temperature adaptations and responses to thermal stress may not protect fall chinook salmon from the recent higher summer water temperatures, altered annual thermal regimes, and degraded cold water refugia that result from hydropower regulation of the Columbia and Snake rivers. The long-term survival of fall chinook salmon will likely require restoration of normal annual thermographs and rigorous changes in land use practices to protect critical thermal refugia and control maximum summer water temperatures in reservoirs.
