Singleton, Royce A; Wolfson, Amy R

2009-05-01

Three independent lines of inquiry have found associations between alcohol use and academic performance, sleep and academic performance, and alcohol use and sleep. The present study bridges this research by examining the links among alcohol use, sleep, and academic performance in college students. Personal interview surveys were conducted with a random sample of 236 students (124 women) at a liberal arts college. The interviews measured alcohol consumption, gender, academic class, weekday and weekend bedtimes and rise times, and daytime sleepiness; 95% of the sample granted permission to obtain grade-point average (GPA) and Scholastic Aptitude Test (SAT) scores from official college records. Ordinary least squares regressions showed that alcohol consumption was a significant predictor of four sleep patterns: the duration of sleep, the timing of sleep, the difference between weekday and weekend nighttime sleep hours (oversleep), and the difference between weekday and weekend bedtimes (bedtime delay). Women and students with late sleep schedules were more apt to report daytime sleepiness. SAT score was the strongest predictor of GPA. However, gender, alcohol consumption, sleep duration, and daytime sleepiness also were significant predictors when other variables were controlled. In addition to alcohol's direct relationship with GPA, mediational analysis indicated that alcohol had indirect effects on sleepiness and GPA, primarily through its effect on sleep schedule. The findings show how alcohol use among college students is related to sleep-wake patterns and further support the connection between alcohol use and grades.

Horng, Eileen L; Evans, Brent J; Antonio, Anthony L; Foster, Jesse D; Kalamkarian, Hoori S; Hurd, Nicole F; Bettinger, Eric P

2013-01-01

This chapter discusses the collaboration between a national college access program, the National College Advising Corps (NCAC), and its research and evaluation team at Stanford University. NCAC is currently active in almost four hundred high schools and through the placement of a recent college graduate to serve as a college adviser provides necessary information and support for students who may find it difficult to navigate the complex college admission process. The advisers also conduct outreach to underclassmen in an effort to improve the school-wide college-going culture. Analyses include examination of both quantitative and qualitative data from numerous sources and partners with every level of the organization from the national office to individual high schools. The authors discuss balancing the pursuit of evaluation goals with academic scholarship. In an effort to benefit other programs seeking to form successful data-driven interventions, the authors provide explicit examples of the partnership and present several examples of how the program has benefited from the data gathered by the evaluation team. © WILEY PERIODICALS, INC.

Science Identity's Influence on Community College Students' Engagement, Persistence, and Performance in Biology

Science.gov (United States)

Riccitelli, Melinda

In the United States (U.S.), student engagement, persistence, and academic performance levels in college science, technology, engineering, and mathematics (STEM) programs have been unsatisfactory over the last decade. Low student engagement, persistence, and academic performance in STEM disciplines have been identified as major obstacles to U.S. economic goals and U.S. science education objectives. The central and salient science identity a college student claims can influence his engagement, persistence, and academic achievement in college science. While science identity studies have been conducted on four-year college populations there is a gap in the literature concerning community college students' science identity and science performance. The purpose of this quantitative correlational study was to examine the relationship between community college students claimed science identities and engagement, persistence, and academic performance. A census sample of 264 community college students enrolled in biology during the summer of 2015 was used to study this relationship. Science identity and engagement levels were calculated using the Science Identity Centrality Scale and the Biology Motivation Questionnaire II, respectively. Persistence and final grade data were collected from institutional and instructor records. Engagement significantly correlated to, r =.534, p = .01, and varied by science identity, p < .001. Percent final grade also varied by science identity (p < .005), but this relationship was weaker (r = .208, p = .01). Results for science identity and engagement and final grade were consistent with the identity literature. Persistence did not vary by science identity in this student sample (chi2 =2.815, p = .421). This result was inconsistent with the literature on science identity and persistence. Quantitative results from this study present a mixed picture of science identity status at the community college level. It is suggested, based on the findings

Thomas, Melissa; Inniss-Richter, Zipporah; Mata, Holly; Cottrell, Randall R

2013-07-01

The importance of career development in professional organizations has been noted in the literature. Personal and professional benefits of membership regardless of discipline can be found across the career spectrum from student to executive. The benefits of professional membership with respect to career development in local chapter organizations have seldom been studied. Local chapter participation may offer significant career development opportunities for the practitioner, faculty member, and student. The purpose of this study was to explore the importance of local chapter involvement to the career development of health education practitioners. An 18-item questionnaire was disseminated to the membership of three local SOPHE (Society for Public Health Education) chapters that explored the level of local chapter involvement and the impact of how specific professional development activities impacted career development. The results of the survey highlighted the importance of continuing education programs, networking, and leadership experience in developing one's career that are offered by local SOPHE chapter involvement. Making a positive impact in the community and earning the respect of one's peers were most often reported as indicators of career success. These factors can directly impact local chapter participation. Career development can certainly be enhanced by active participation in the local chapter of a professional association.

Class start times, sleep, and academic performance in college: a path analysis.

Science.gov (United States)

Onyper, Serge V; Thacher, Pamela V; Gilbert, Jack W; Gradess, Samuel G

2012-04-01

Path analysis was used to examine the relationship between class start times, sleep, circadian preference, and academic performance in college-aged adults. Consistent with observations in middle and high school students, college students with later class start times slept longer, experienced less daytime sleepiness, and were less likely to miss class. Chronotype was an important moderator of sleep schedules and daytime functioning; those with morning preference went to bed and woke up earlier and functioned better throughout the day. The benefits of taking later classes did not extend to academic performance, however; grades were somewhat lower in students with predominantly late class schedules. Furthermore, students taking later classes were at greater risk for increased alcohol consumption, and among all the factors affecting academic performance, alcohol misuse exerted the strongest effect. Thus, these results indicate that later class start times in college, while allowing for more sleep, also increase the likelihood of alcohol misuse, ultimately impeding academic success.

Full Text Available BACKGROUND: Alcoholic beverages are widely available in the university environment, particularly at the parties. There are few studies addressing the relationship between alcohol consumption and academic performance among college students. OBJECTIVE: This study evaluated the behavior of college students regarding the profile of alcohol consumption and its academic consequences. METHODS: The volunteers (343 students answered a questionnaire about their pattern of alcohol consumption and possible related behaviors, especially academic performance. Participants were classified as "non-drinkers" (ND, "non-binge drinkers" (nBD, "binge drinkers" (BD and "heavy drinkers" (HD. RESULTS: 88.1% of the students reported ingesting alcoholic beverages, 44% as BD. Most of the drinker students (75.5% - nBD, BD or HD stated getting intoxicated at least once a month. Binge drinking was the predominant pattern (66.2% of those who drank. HD students presented a risk 9.2 times higher of not being in the ideal period of the course. DISCUSSION: The college students evaluated presented high rates of alcohol abuse. Binge drinking might have interfered in their academic performance. Organic, social and behavioral consequences were also reported.

High school and college biology: A multi-level model of the effects of high school biology courses on student academic performance in introductory college biology courses

Science.gov (United States)

Loehr, John Francis

The issue of student preparation for college study in science has been an ongoing concern for both college-bound students and educators of various levels. This study uses a national sample of college students enrolled in introductory biology courses to address the relationship between high school biology preparation and subsequent introductory college biology performance. Multi-Level Modeling was used to investigate the relationship between students' high school science and mathematics experiences and college biology performance. This analysis controls for student demographic and educational background factors along with factors associated with the college or university attended. The results indicated that high school course-taking and science instructional experiences have the largest impact on student achievement in the first introductory college biology course. In particular, enrollment in courses, such as high school Calculus and Advanced Placement (AP) Biology, along with biology course content that focuses on developing a deep understanding of the topics is found to be positively associated with student achievement in introductory college biology. On the other hand, experiencing high numbers of laboratory activities, demonstrations, and independent projects along with higher levels of laboratory freedom are associated with negative achievement. These findings are relevant to high school biology teachers, college students, their parents, and educators looking beyond the goal of high school graduation.

Generic Performance Measures. Chapter 8

Energy Technology Data Exchange (ETDEWEB)

Daube-Witherspoon, M. E. [Department of Radiology, University of Pennsylvania, Philadelphia, PA (United States)

2014-12-15

The generic nuclear medicine imager, whether a gamma camera, single photon emission computed tomography (SPECT) system or positron emission tomography (PET) scanner, comprises several main components: a detection system, a form of collimation to select γ rays at specific angles, electronics and a computing system to create the map of the radiotracer distribution. This section discusses these components in more detail. The first stage of a generic nuclear medicine imager is the detection of the γ rays emitted by the radionuclide. In the case of PET, the radiation of interest are the 511 keV annihilation photons that result from the interaction of the positron emitted by the radionuclide with an electron in the tissue. For general nuclear medicine and SPECT, there is one or sometimes more than one γ ray of interest, with energies in the range of <100 to >400 keV. The γ rays are detected when they interact and deposit energy in the crystal(s) of the imaging system. There are two main types of detector: crystals that give off light that can be converted to an electrical signal when the γ ray interacts (‘scintillators’) and semiconductors, crystals that generate an electrical signal directly when the γ ray deposits energy in the crystal. Scintillation detectors include NaI(Tl), bismuth germanate (BGO) and lutetium oxyorthosilicate (LSO); semiconductor detectors used in nuclear medicine imagers include cadmium zinc telluride (CZT). Radiation detectors are described in more detail in Chapter 6.

Zanzonico, P. B. [Department of Medical Physics, Memorial Sloan Kettering Cancer Center, New York (United States)

2014-12-15

Historically, nuclear medicine has been largely an imaging based specialty, employing such diverse and increasingly sophisticated modalities as rectilinear scanning, (planar) gamma camera imaging, single photon emission computed tomography (SPECT) and positron emission tomography (PET). Non-imaging radiation detection, however, remains an essential component of nuclear medicine. This chapter reviews the operating principles, performance, applications and quality control (QC) of the various non-imaging radiation detection and measurement devices used in nuclear medicine, including survey meters, dose calibrators, well counters, intra-operative probes and organ uptake probes. Related topics, including the basics of radiation detection, statistics of nuclear counting, electronics, generic instrumentation performance parameters and nuclear medicine imaging devices, are reviewed in depth in other chapters of this book.

Schneider, Erin; Chesky, Kris

2011-09-01

This study characterized perceived social support and performance anxiety of college music students, compared characteristics to those of non-music majors, and explored the relationships between social support and performance anxiety. Subjects (n = 609) completed a questionnaire that included demographics, the Multidimensional Scale of Perceived Social Support (MSPSS), and visual analog scale measures of performance anxiety. Results showed that music majors perceived significantly lower levels of social support from significant others when compared to non-music majors. Perceived social support was significantly correlated with measures of performance anxiety. Students with greater perceived social support reported less frequent anxiety and lower levels of impact of anxiety on ability to perform. These findings may have practical implications for schools of music and conservatories.

Full Text Available Business incubators have a very important role in developing entrepreneurship, since it gives large opportunity to its participants to develop their business skill during incubation. The Indonesian government today provides a major boost to the development of business incubators in universities or other form of higher education institutions. The purpose of this research is to analyze the validation of the establishment of business incubator in colleges. In Ministerial Regulation (Permen Minister of Cooperation and Small Medium Entrepreneurship the Republic of Indonesia No. 24/2015 explained that the head of the university, the Rector or the Director may issue a business incubators license. Thus, internal validation can be done by university or college management through the issuance of Decree (SK Establishment complete with personnel appointed as manager. Furthermore, the college, has to provide a place or room consisting of office space, tenant room at least 3, discussion room 1, and tenant production display room. External validation is carried out by tenants through their success of becoming independent businessmen after being forged or incubated in a business incubator for a maximum of 3 years in one incubation period.

Experience, gender, and performance: Connecting high school physics experience and gender differences to introductory college physics performance

Science.gov (United States)

Tai, Robert H.

Current science educational practice is coming under heavy criticism based on the dismaying results of the Third International Mathematics and Science Study of 1998, the latest in a series of large scale surveys; and from research showing the appallingly low representation of females in science-related fields. These critical evaluations serve to draw attention to science literacy in general and lack of persistence among females in particular, two issues that relate closely to the "preparation for future study" goal held by many high school science teachers. In other words, these teachers often seek to promote future success and to prevent future failure in their students' academic careers. This thesis studies the connection between the teaching practices recommended by reformers and researchers for high school teachers, and their students' subsequent college physics performance. The teaching practices studied were: laboratory experiences, class discussion experiences, content coverage, and reliance on textbooks. This study analyzed a survey of 1500 students from 16 different lecture-format college physics courses at 14 different universities. Using hierarchical linear modeling, this study accounted for course-level variables (Calculus-based/Non-calculus course type, professor's gender, and university selectivity). This study controlled for the student's parents education, high school science/mathematics achievement, high school calculus background, and racial background. In addition, the interactions between gender and both pedagogical/curricular and course-level variables were analyzed. The results indicated that teaching fewer topics in greater depth in high school physics appeared to be helpful to college physics students. An interaction between college course type and content coverage showed that students in Calculus-based physics reaped even greater benefits from a depth-oriented curriculum. Also students with fewer labs per month in high school physics

Image Perception and Assessment. Chapter 18

Energy Technology Data Exchange (ETDEWEB)

Reiser, I. [University of Chicago, Chicago (United States)

2014-09-15

The main purpose of a medical image is to provide information to a human reader, such as a radiologist, so that a diagnosis can be reached — rather than to display the beauty of the human internal workings. It is important to understand how the human visual system affects the perception of contrast and spatial resolution of structures that are present in the image. If the image is not properly displayed, or the environment is not appropriate, subtle clinical signs may go unnoticed, which can potentially lead to a misdiagnosis. This chapter provides an introduction to human visual perception and task based objective assessment of an imaging system. A model for the contrast sensitivity of the human visual system is presented. This model is used to derive the greyscale standard display function for medical displays. Task based assessment measures the quality of an imaging system as the ability of an observer to perform a well defined task, based on a set of images. Metrics for observer performance are introduced, as well as experimental methodologies for the measurement of human performance. The last section of the chapter describes the estimation of task performance based on mathematical observer models.

Full Text Available The purpose of this study was to analyze the motor performance of fundamental motor skills and physical activity habits of students at the University of Costa Rica. A total of 92 males and 48 females (M age = 19.78 yr., SD = 4.72 yr. enrolled in different Sports Activity courses taught at the Rodrigo Facio campus was assessed. The Instrument for the Evaluation of Fundamental Movement Patterns was used to assess motor performance in eight fundamental movement patterns (running, jumping, galloping, catching, throwing, bouncing, and kicking. The physical activity level was obtained from a self-reported questionnaire developed for such purpose. Results show that 28% of the participants were physically active. Participants presented a proficient performance in kicking, running, and galloping, but a non-proficient performance in jumping, hopping, bouncing, throwing and catching. Physical activity behavior was related to the overall performance of the motor skills assessed (Rho = .233; p = .006. In conclusion, college students presented a proficient performance on three of the eight skills assessed. In addition, a relationship was found between physical activity levels and performance. Physical Education teachers are recommended to develop activities to enhance motor performance of fundamental motor skills in college students.

Radiation Protection. Chapter 24

Sutton, D. [Ninewells Hospital, Dundee (United Kingdom); Collins, L. T. [Westmead Hospital, Sydney (Australia); Le Heron, J. [International Atomic Energy Agency, Vienna (Austria)

2014-09-15

Chapter 21, in describing basic radiation biology and radiation effects, demonstrates the need to have a system of radiation protection that allows the many beneficial uses of radiation to be realized while ensuring detrimental radiation effects are either prevented or minimized. This can be achieved with the twin objectives of preventing the occurrence of deterministic effects and of limiting the probability of stochastic effects to a level that is considered acceptable. In a radiology facility, consideration needs to be given to the patient, the staff involved in performing the radiological procedures, members of the public and other staff that may be in the radiology facility, carers and comforters of patients undergoing procedures, and persons who may be undergoing a radiological procedure as part of a biomedical research project. This chapter discusses how the objectives given above are fulfilled through a system of radiation protection and how such a system should be applied practically in a radiology facility.

Lack of physical activity is a contributor to the obesity epidemic and is speculated to relate to reduced academic performance; however, this link has yet to be examined within the college population. The purpose of this study in a group of undergraduate students, was to determine if aerobic exercise activity was related to academic performance. The participants for this study included 740 students at multiple universities enrolled in nursing and kinesiology studies. The participants completed the Leisure and Physical Activity Questionnaire. Pearson's χ(2) analysis revealed differences in grade point average with aerobic activity (χ(2) = 44.29, P ≤ 0.001) as well as a trend toward differences in grade point average with weightlifting activity (χ(2) = 22.69, P = 0.61). Based on these findings it can be suggested that college students engage in greater aerobic exercise.

Hiles, P. A. [Glan Clwyd Hospital, Bodelwyddan (United Kingdom); McLean, I. D. [International Atomic Energy Agency, Vienna (Austria); Christofides, S. [New Nicosia General Hospital, Nicosia (Cyprus)

2014-09-15

This chapter introduces the principles and definitions of quality management systems (QMSs) for radiology facilities, to give a framework to assist in the setting up of such systems and to emphasize the role of the medical physicist in this context. While there is a diversity of terms currently in use to describe quality processes both generally and specifically within radiology, there is broad agreement that the effective management of radiation medicine services demands a quality culture that includes a systematic approach to the elements that govern the delivery of that service. Therefore, the concept of quality assurance (QA) within the radiological facility covers, in its widest sense, all those factors that affect the intended outcome, that is, a clinical diagnosis. The medical physicist has an important role in the overall QMS, especially, but not exclusively, with respect to the equipment performance. A worked example of a quality control (QC) programme is included at the end of the chapter, to demonstrate the depth of detail and involvement of the medical physicist.

Engquist, Katherine D; Smith, Craig A; Chimera, Nicole J; Warren, Meghan

2015-08-01

Although various studies have assessed performance of athletes on the Functional Movement Screen (FMS) and the Y Balance Test (YBT), no study to date has directly evaluated a comparison of performance between athletes and members of the general population. Thus, to better understand the application of the FMS and the YBT to general college students, this study examined whether or not general college students performed similarly to student-athletes on the FMS (composite and movement pattern scores) and the YBT (composite and reach directions). This study evaluated 167 Division I student-athletes and 103 general college students from the same university on the FMS and the YBT. No difference was found in FMS composite scores between student-athletes and general college students. For FMS movement patterns, female student-athletes scored higher than general college students in the deep squat. No difference was found for men in any FMS movement pattern. Female student-athletes scored higher than female general college students in YBT composite scores; no difference was found for men in YBT composite scores. In analysis of YBT reach directions, female student-athletes scored higher than female general college students in all reach directions, whereas no difference was found in men. Existing research on the FMS composite score in athletic populations may apply to a general college population for the purposes of preparticipation screening, injury prediction, etc. Existing research on the YBT in male athletic populations is expected to apply equally to general college males for the purposes of preparticipation screening, injury prediction, etc.

Full Text Available Three residential colleges located in Kuala Lumpur, Malaysia, were selected for energy performance analysis in regards to its implementation of bioclimatic design strategies. Specifically, passive design strategies on daylighting and natural ventilation were examined. In Malaysia, the residential college or hostel is a multi-residential building providing accommodation to university students. The three residential colleges in this study, namely C1, C2 and C3, were built in different years with different designs and forms, particularly with regards to enclosure and facade design, solar control devices, passive daylight concepts, and natural ventilation strategies. The building designs were carefully studied and an electric consumption analysis was carried out in each residential college. This study revealed that the wide-scale implementation of bioclimatic design strategies in college C2 help reduced the annual energy consumption. The building bioclimatic design features that are accountable to reduce energy consumption are the internal courtyard and balconies on each unit of floor area, as shown in C3.Results from this study highly recommend internal courtyard and balcony building combination for multi residential building design, especially in tropical urban regions.

In this chapter, we illustrate benefits of thinking in terms of thread management techniques when using a centralized scheduler model along with interoperability of MPI and PThread. This is facilitated through an exploration of thread placement strategies for an algorithm modeling radiative heat transfer with special attention to the 61st core. This algorithm plays a key role within the Uintah Computational Framework (UCF) and current efforts taking place at the University of Utah to model next-generation, large-scale clean coal boilers. In such simulations, this algorithm models the dominant form of heat transfer and consumes a large portion of compute time. Exemplified by a real-world example, this chapter presents our early efforts in porting a key portion of a scalability-centric codebase to the Intel Xeon Phi coprocessor. Specifically, this chapter presents results from our experiments profiling the native execution of a reverse Monte-Carlo ray tracing-based radiation model on a single coprocessor. These results demonstrate that our fastest run configurations utilized the 61st core and that performance was not profoundly impacted when explicitly oversubscribing the coprocessor operating system thread. Additionally, this chapter presents a portion of radiation model source code, a MIC-centric UCF cross-compilation example, and less conventional thread management technique for developers utilizing the PThreads threading model.

Predictors of science success: The impact of motivation and learning strategies on college chemistry performance

Science.gov (United States)

Obrentz, Shari B.

As the number of college students studying science continues to grow, it is important to identify variables that predict their success. The literature indicates that motivation and learning strategy use facilitate science success. Research findings show these variables can change throughout a semester and differ by performance level, gender and ethnicity. However, significant predictors of performance vary by research study and by group. The current study looks beyond the traditional predictors of grade point averages, SAT scores and completion of advanced placement (AP) chemistry to consider a comprehensive set of variables not previously investigated within the same study. Research questions address the predictive ability of motivation constructs and learning strategies for success in introductory college chemistry, how these variables change throughout a semester, and how they differ by performance level, gender and ethnicity. Participants were 413 introductory college chemistry students at a highly selective university in the southeast. Participants completed the Chemistry Motivation Questionnaire (CMQ) and Learning Strategies section of the Motivated Strategies for Learning Questionnaire (MSLQ) three times during the semester. Self-efficacy, effort regulation, assessment anxiety and previous achievement were significant predictors of chemistry course success. Levels of motivation changed with significant decreases in self-efficacy and increases in personal relevance and assessment anxiety. Learning strategy use changed with significant increases in elaboration, critical thinking, metacognitive self-regulation skills and peer learning, and significant decreases in time and study management and effort regulation. High course performers reported the highest levels of motivation and learning strategy use. Females reported lower intrinsic motivation, personal relevance, self-efficacy and critical thinking, and higher assessment anxiety, rehearsal and organization

2016-09-18

It is critical that our alcohol screening instruments maintain their accuracy at detecting DSM-5 Alcohol Use Disorder (AUD) symptomatology. The Alcohol Use Disorders Identification Test (AUDIT) is one of the most widely used alcohol screening instruments, despite no studies evaluating its performance for detecting DSM-5 AUDs. The present study evaluated the performance of the AUDIT in the screening of DSM-5 AUDs in non-treatment seeking college students. Participants (N = 251) were undergraduate students who had at least one binge drinking occasion in the past 90-days. The AUROC value for DSM-5 AUD status in the overall sample was.779 (SE =.029; 95% CIs =.721 to.837). The AUROC values for the reference groups of any DSM-IV AUD and any binge drinker were.798 (SE =.028; 95% CIs =.742 to.853) and.827 (SE =.03; 95% CIs.768 -.886), respectively. A similar pattern of findings emerged between males and females. Gender differences emerged in the identification of AUDIT cut-off scores. A score of ≥ 8 and ≥ 9 had the best balance of sensitivity and specificity for females and males in college, respectively. Findings indicate that the AUDIT has a reasonable degree of diagnostic proficiency in screening for DSM-5 AUDs in college students.

Davis, Kelly D; Winsler, Adam; Middleton, Michael

2006-06-01

In the present study, the authors examined college students' (N= 136) perceptions of the provision of extrinsic rewards given by parents and teachers for academic performance from elementary school through high school. They also examined the relations between reward history and present student motivational orientation. External rewards for students' grades were common at all levels of schooling. Reward history related significantly to students' motivational orientation and performance in college, and these relations were generally stronger for boys than for girls. The authors discuss implications of these findings.

Test Scores, Class Rank and College Performance: Lessons for Broadening Access and Promoting Success.

Science.gov (United States)

Niu, Sunny X; Tienda, Marta

2012-04-01

Using administrative data for five Texas universities that differ in selectivity, this study evaluates the relative influence of two key indicators for college success-high school class rank and standardized tests. Empirical results show that class rank is the superior predictor of college performance and that test score advantages do not insulate lower ranked students from academic underperformance. Using the UT-Austin campus as a test case, we conduct a simulation to evaluate the consequences of capping students admitted automatically using both achievement metrics. We find that using class rank to cap the number of students eligible for automatic admission would have roughly uniform impacts across high schools, but imposing a minimum test score threshold on all students would have highly unequal consequences by greatly reduce the admission eligibility of the highest performing students who attend poor high schools while not jeopardizing admissibility of students who attend affluent high schools. We discuss the implications of the Texas admissions experiment for higher education in Europe.

Butler, Robert J; Lehr, Michael E; Fink, Michael L; Kiesel, Kyle B; Plisky, Phillip J

2013-09-01

Field expedient screening tools that can identify individuals at an elevated risk for injury are needed to minimize time loss in American football players. Previous research has suggested that poor dynamic balance may be associated with an elevated risk for injury in athletes; however, this has yet to be examined in college football players. To determine if dynamic balance deficits are associated with an elevated risk of injury in collegiate football players. It was hypothesized that football players with lower performance and increased asymmetry in dynamic balance would be at an elevated risk for sustaining a noncontact lower extremity injury. Prospective cohort study. Fifty-nine collegiate American football players volunteered for this study. Demographic information, injury history, and dynamic balance testing performance were collected, and noncontact lower extremity injuries were recorded over the course of the season. Receiver operator characteristic curves were calculated based on performance on the Star Excursion Balance Test (SEBT), including composite score and asymmetry, to determine the population-specific risk cut-off point. Relative risk was then calculated based on these variables, as well as previous injury. A cut-off point of 89.6% composite score on the SEBT optimized the sensitivity (100%) and specificity (71.7%). A college football player who scored below 89.6% was 3.5 times more likely to get injured. Poor performance on the SEBT may be related to an increased risk for sustaining a noncontact lower extremity injury over the course of a competitive American football season. College football players should be screened preseason using the SEBT to identify those at an elevated risk for injury based upon dynamic balance performance to implement injury mitigation strategies to this specific subgroup of athletes.

Chapter 12. Space Heating Equipment

Energy Technology Data Exchange (ETDEWEB)

Rafferty, Kevin D.

1998-01-01

The performance evaluation of space heating equipment for a geothermal application is generally considered from either of two perspectives: (a) selecting equipment for installation in new construction, or (b) evaluating the performance and retrofit requirements of an existing system. With regard to new construction, the procedure is relatively straightforward. Once the heating requirements are determined, the process need only involve the selection of appropriately sized hot water heating equipment based on the available water temperature. It is important to remember that space heating equipment for geothermal applications is the same equipment used in non-geothermal applications. What makes geothermal applications unique is that the equipment is generally applied at temperatures and flow rates that depart significantly from traditional heating system design. This chapter presents general considerations for the performance of heating equipment at non-standard temperature and flow conditions, retrofit of existing systems, and aspects of domestic hot water heating.

The differential absorption of X rays in tissues and organs, owing to their atomic composition, is the basis for the various imaging methods used in diagnostic radiology. The principles in the production of X rays have remained the same since their discovery. However, much refinement has gone into the design of X ray tubes to achieve the performance required for today’s radiological examinations. In this chapter, an outline of the principles of X ray production and a characterization of the radiation output of X ray tubes will be given. The basic processes producing X rays are dealt with in Section 1.4.

McKinnon-Howe, Leah; Dowdall, Jayme

2018-05-01

The goal of this study was to identify knowledge gaps in clinicians who evaluate and treat performing artists for illnesses and injuries that affect vocal function in college health settings. This pilot study utilized a web-based cross-sectional survey design incorporating common clinical scenarios to test knowledge of evaluation and management strategies in the vocal performing artist. A web-based survey was administered to a purposive sample of 28 clinicians to identify the approach utilized to evaluate and treat vocal performing artists in college health settings, and factors that might affect knowledge gaps and influence referral patterns to voice specialists. Twenty-eight clinicians were surveyed, with 36% of respondents incorrectly identifying appropriate vocal hygiene measures, 56% of respondents failing to identify symptoms of vocal fold hemorrhage, 84% failing to identify other indications for referral to a voice specialist, 96% of respondents acknowledging unfamiliarity with the Voice Handicap Index and the Singers Voice Handicap Index, and 68% acknowledging unfamiliarity with the Reflux Symptom Index. The data elucidated specific knowledge gaps in college health providers who are responsible for evaluating and treating common illnesses that affect vocal function, and triaging and referring students experiencing symptoms of potential vocal emergencies. Future work is needed to improve the standard of care for this population. Copyright © 2018 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

Full Text Available Most college students sit 14 hours per week on average, excluding sedentary study time. Researchers observing workplace and elementary school settings with active workstations to combat sedentary behavior have shown enhanced cognition without distraction. Until now, incorporating active workstations in college classroom settings remained relatively unexplored. This study’s purpose was to assess academic performance using in-class stationary cycle desks during a semester-long lecture course. Twenty-one college students (19–24 years enrolled in a lecture course volunteered and were split into traditional sit (SIT and stationary cycle (CYC groups randomly, matched on a calculated factor equal to a physical activity (PA score (0–680 multiplied by grade point average (GPA; 4.0 scale. CYC pedaled a prescribed rate of perceived exertion (RPE of less than 2 out of 10 during a 50-min lecture, 3 × week for 12 weeks. CYC averaged 42 min, 7.9 miles, and 1.7 RPE during class throughout the semester. No significant differences (p > 0.05 were observed between CYC and SIT on in-class test scores or overall course grades. Although statistically insignificant, CYC had higher mean test scores and overall course grades vs. SIT (i.e., B+ vs. B, respectively. Low intensity cycling during a college lecture course maintained student academic performance and possibly reduced weekly sedentary behavior time.

Time-to-event analysis as a framework for quantifying fish passage performance: Chapter 9.1

Science.gov (United States)

Castro-Santos, Theodore R.; Perry, Russell W.; Adams, Noah S.; Beeman, John W.; Eiler, John H.

2012-01-01

Fish passage is the result of a sequence of processes, whereby fish must approach, enter, and pass a structure. Each of these processes takes time, and fishway performance is best quantified in terms of the rates at which each process is completed. Optimal performance is achieved by maximizing the rates of approach, entry, and passage through safe and desirable routes. Sometimes, however, it is necessary to reduce rates of passage through less desirable routes in order to increase proportions passing through the preferred route. Effectiveness of operational or structural modifications for achieving either of these goals is best quantified by applying time-to-event analysis, commonly known as survival analysis methods, to telemetry data. This set of techniques allows for accurate estimation of passage rates and covariate effects on those rates. Importantly, it allows researchers to quantify rates that vary over time, as well as the effects of covariates that also vary over time. Finally, these methods are able to control for competing risks, i.e., the presence of alternate passage routes, failure to pass, or other fates that remove fish from the pool of candidates available to pass through a particular route. In this chapter, we present a model simulation of telemetered fish passing a hydroelectric dam, and provide step-by-step guidance and rationales for performing time-to-event analysis on the resulting data. We demonstrate how this approach removes bias from performance estimates that can result from using methods that focus only on proportions passing each route. Time-to-event analysis, coupled with multinomial models for measuring survival, provides a comprehensive set of techniques for quantifying fish passage, and a framework from which performance among different sites can be better understood.

Taylor, Daniel J; Vatthauer, Karlyn E; Bramoweth, Adam D; Ruggero, Camilo; Roane, Brandy

2013-01-01

Few studies have looked at the predictability of academic performance (i.e., cumulative grade point average [GPA]) using sleep when common nonsleep predictors of academic performance are included. This project studied psychological, demographic, educational, and sleep risk factors of decreased academic performance in college undergraduates. Participants (N = 867) completed a questionnaire packet and sleep diary. It was hypothesized that low total sleep time (TST), increased sleep onset latency, later bedtimes, later wake times, and TST inconsistency would predict decreased academic performance. The most significant predictors of academic performance were high school GPA, standardized test scores (i.e., SAT/ACT), TST, time awake before arising (TWAK), TST inconsistency, and the quadratic terms of perceived stress (PSS) and TST.

Future so bright? Delay discounting and consideration of future consequences predict academic performance among college drinkers.

Science.gov (United States)

Acuff, Samuel F; Soltis, Kathryn E; Dennhardt, Ashley A; Borsari, Brian; Martens, Matthew P; Murphy, James G

2017-10-01

College student drinking is a major public health concern and can result in a range of negative consequences, from acute health risks to decreased academic performance and drop out. Harm reduction interventions have been developed to reduce problems associated with drinking but there is a need to identify specific risk/protective factors related to academic performance among college drinkers. Behavioral economics suggests that chronic alcohol misuse reflects a dysregulated behavioral process or reinforcer pathology-alcohol is overvalued and the value of prosocial rewards are sharply discounted due, in part, to their delay. This study examined delay discounting, consideration of future consequences (CFC) and protective behavioral strategies (PBS) as predictors of academic success (grade point average; GPA) and engagement (time devoted to academic activities) among 393 college drinkers (61% female). In multivariate models, PBS were associated with greater academic engagement, but were not with academic success. Lower discounting of delayed rewards and greater CFC were associated with both academic success and engagement among drinkers. Previous research suggests that future time orientation is malleable, and the current results provide support for efforts to enhance future time orientation as part of alcohol harm-reduction approaches.

Mclean, I. D. [International Atomic Energy Agency, Vienna (Austria); Shepherd, J. A. [University of California at San Francisco, San Francisco, United States of America (United States)

2014-09-15

Up to this point, this handbook has described the use of X rays to form 2-D medical images of the 3-D patient. This process of reducing patient information by one dimension results in an image of superimposed tissues where important information might be obscured. Chapter 11 begins a section of the book involving the creation of cross-sectional medical images through computed tomography (CT), ultrasound and magnetic resonance imaging (MRI). This Chapter describes a number of special X ray imaging modalities and their associated techniques, and forms a transition between projection and cross-sectional imaging. The first of these special topics is dental radiography, which is characterized by a diversity of technology and innovation. The common intraoral radiograph of a single tooth has seen little fundamental change since the time of Roentgen and is, today, along with the simple chest radiograph, the most commonly performed radiographic examination. By contrast, the challenge to create an image of all the teeth simultaneously has placed dentistry at the cutting edge of technology, through the development of panographic techniques and, most recently, with the application of cone beam CT (CBCT). Moreover, the small size of the tooth and the consequent reduced need for X ray generation power promotes equipment mobility. The effect of the need for equipment mobility also forms a special topic that is examined in this chapter. Quantification of the composition of the body is another special X ray imaging technique. Dual energy X ray absorptiometry (DXA) is primarily used to derive the mass of one material in the presence of another, through knowledge of their unique X ray attenuation at different energies. DXA’s primary commercial application has been to measure body mineral density as an assessment of fracture risk and to diagnose osteoporosis; thus, the X ray energies used are optimized for bone density assessment. Currently, there are estimated to be over 50 000

Science Self-Efficacy and Innovative Behavior (IB) in Nigerian College Students Enrolled in Science, Technology, Engineering, and Mathematics (STEM) Programs

Science.gov (United States)

Okonkwo, Charles

This study will explore how science self-efficacy among college students in science, technology, engineering, and mathematics (STEM) fields in Nigeria predicts their innovation. Several reports on African development argue that science, technology and innovation underpin targets for dramatically reducing poverty in its many dimensions---income poverty, hunger, disease, exclusion, lack of infrastructure and shelter---while promoting gender equality, education, health, and environmental sustainability (UN Millennium Project, 2005). If African countries in general, including Nigeria, are to move from the exploitation of natural resources to technological innovation as the foundation for development, stakeholders in these countries must encourage development of individual ability to innovate products, services and work processes in crucial organizations (DeJong & DenHartog, 2010). The common denominator in the scientific and technological development of any country or organization is the individuals that make up these entities. An individual's engagement is the foundation for group motivation, innovation and improvement. These ideas inform the purpose of this study: to investigate how science self-efficacy among college students in various engineering fields in Nigeria predicts self-reported innovative behavior (IB), also referred to as Innovative Work Behavior (IWB). IB involves initiating new and useful ideas, processes, products or procedures, as well as the process of implementing these ideas (Farr & Ford, 1990; Scott & Bruce, 1994). The general findings of this study align with the dictates of social cognitive theory. Specifically, research indicates self-efficacy has the most predictive power for performance when it is measured at a level specific to the expected task (Bandura, 1997; Pajares, 1996). The findings from the hierarchical multiple regressions confirm that individuals' perceived science efficacy plays an important role in their perceived self

2018-01-01

Full Text Available With the demand of culinary arts graduates in hospitality industry, more higher learning institutions especially private colleges offer the programs. The course syllabus of culinary arts is specifically designed to provide a strong foundation for students who aspire to be chefs in the local and international fields. Students are equipped with a basic education in the culinary skills and knowledge associated with the cognitive and psychomotor domain. This study investigates the influence of the cognitive and psychomotor domain effect to private college student’s performance after internship. The internship program is gradually enhancing the students’ knowledge; confidence level and psychomotor performance which enable them to at least gain confidence when performing their practical assessment after coming back from internship. This is a positive indication in the beginning of the students’ life before expose into a real life work situation. Thus, this research can be a guidance for the private institutional lecturers to look into the effectiveness of cognitive and psychomotor domain of culinary art students’ performance in their internship programs.

Liew, Jeffrey; Lench, Heather C; Kao, Grace; Yeh, Yu-Chen; Kwok, Oi-man

2014-01-01

Standardized testing has become a common form of student evaluation with high stakes, and limited research exists on understanding the roles of students' personality traits and social-evaluative threat on their academic performance. This study examined the roles of avoidance temperament (i.e., fear and behavioral inhibition) and evaluative threat (i.e., fear of failure and being viewed as unintelligent) in standardized math test and course grades in college students. Undergraduate students (N=184) from a large public university were assessed on temperamental fear and behavioral inhibition. They were then given 15 minutes to complete a standardized math test. After the test, students provided data on evaluative threat and their math performance (scores on standardized college entrance exam and average grades in college math courses). Results indicate that avoidance temperament was linked to social-evaluative threat and low standardized math test scores. Furthermore, evaluative threat mediated the influence of avoidance temperament on both types of math performance. Results have educational and clinical implications, particularly for students at risk for test anxiety and underperformance. Interventions targeting emotion regulation and stress management skills may help individuals reduce their math and test anxieties.

Early transition metal carbides and nitrides (ETMCNs), materials in which carbon or nitrogen occupies interstitial sites within a parent metal lattice, possess unique physical and chemical properties that motivate their use as catalysts. Specifically, these materials possess multiple types of catalytic sites, including metallic, acidic, and basic sites, and as such, exhibit reactivities that differ from their parent metals. Moreover, their surfaces are dynamic under reaction conditions. This chapter reviews recent (since 2010) experimental and computational investigations into the catalytic properties of ETMCN materials for applications including biomass conversion, syngas and CO2 upgrading, petroleum and natural gas refining, and electrocatalytic energy conversion, energy storage, and chemicals production, and attempts to link catalyst performance to active site identity/surface structure in order to elucidate the present level of understanding of structure-function relationships for these materials. The chapter concludes with a perspective on leveraging the unique properties of these materials to design and develop improved catalysts through a dedicated, multidisciplinary effort.

Depression is a major health concern for college students due to its substantial morbidity and mortality. Although low parental education has been identified as a factor in depression in college students, the mechanisms through which parental educational achievement affects students' depression are not well understood. We tested whether adverse family and college environments mediate the relationship between parental educational level and depression among Chinese college students. A total of 5180 respondents were selected using a cross-sectional survey. We examined the association of parental education, adverse family and college environments with depression in college students using the Adolescent Self-Rating Life Events Checklist, Beck Depression Inventory and socio-demographic questionnaires. Lower parental educational level is significantly correlated with depression in college students in our sample. Additionally, low family economic status, paternal or maternal unemployment, long periods spent apart from family, family conflicts, having been scolded and beaten by parents, poor or dissatisfying test performance, conflict with friends, heavy course load and failure in selection processes are also associated with parental education. Low family economic status, paternal or maternal unemployment, long periods spent apart from family, family conflicts, poor or dissatisfying test performance, conflict with friends and heavy course load mediated the relationship between parental education and depression in college students. Adverse family and college environments could explain the influence of parental educational level on depression in college students.

Fundamentals of Dosimetry. Chapter 3

Energy Technology Data Exchange (ETDEWEB)

Yoshimura, E. M. [Universidade de São Paulo, São Paulo (Brazil)

2014-09-15

Determination of the energy imparted to matter by radiation is the subject of dosimetry. The energy deposited as radiation interacts with atoms of the material, as seen in the previous chapter. The imparted energy is responsible for the effects that radiation causes in matter, for instance, a rise in temperature, or chemical or physical changes in the material properties. Several of the changes produced in matter by radiation are proportional to the absorbed dose, giving rise to the possibility of using the material as the sensitive part of a dosimeter. Also, the biological effects of radiation depend on the absorbed dose. A set of quantities related to the radiation field is also defined within the scope of dosimetry. It will be shown in this chapter that, under special conditions, there are simple relations between dosimetric and field description quantities. Thus, the framework of dosimetry is the set of physical and operational quantities that are studied in this chapter.

2015-02-01

Full Text Available The cell phone is ever-present on college campuses and is frequently used in settings where learning occurs. This study assessed the relationship between cell phone use and actual college grade point average (GPA after controlling for known predictors. As such, 536 undergraduate students from 82 self-reported majors at a large, public university were sampled. A hierarchical regression (R2 = .449 demonstrated that cell phone use was significantly (p < .001 and negatively (β = −.164 related to actual college GPA after controlling for demographic variables, self-efficacy for self-regulated learning, self-efficacy for academic achievement, and actual high school GPA, which were all significant predictors (p < .05. Thus, after controlling for other established predictors, increased cell phone use was associated with decreased academic performance. Although more research is needed to identify the underlying mechanisms, findings suggest a need to sensitize students and educators about the potential academic risks associated with high-frequency cell phone use.

Full Text Available There is concern that online education may widen the achievement gap between students from different socioeconomic classes. The recent discussion of integrating massive open online courses (MOOCs into formal higher education has added fuel to this debate. In this study, factors influencing enrollment and completion in a pre-college preparatory MOOC were explored. University of California at Irvine (UCI students of all preparation levels, defined by math Scholastic Aptitude Test (SAT score, were invited to take a Bio Prep MOOC to help them prepare for introductory biology. Students with math SAT below 550 were offered the explicit incentive of an early change to the biology major upon successful completion of the MOOC and two additional onsite courses. Our results demonstrate that, among course registrants, a higher percentage of UCI students (>60% completed the course than non-UCI registrants from the general population (<9%. Female UCI students had a greater likelihood of enrolling in the MOOC, but were not different from male students in terms of performance. University students entering with low preparation outperformed students entering who already had the credentials to become biology majors. These findings suggest that MOOCs can reach students, even those entering college with less preparation, before they enter university and have the potential to prepare them for challenging science, technology, engineering, and mathematics (STEM courses.

The profile of students’ misconceptions shows that students have misconceptions in each sub-chapter. The cause of misconceptions came from preconceptions, associative thinking, reasoning, intuition, and false negative. The highest cause of misconception in this chapter is student’s humanistic thinking.

Melt inclusions: Chapter 6

Science.gov (United States)

,; Lowenstern, J. B.

2014-01-01

Melt inclusions are small droplets of silicate melt that are trapped in minerals during their growth in a magma. Once formed, they commonly retain much of their initial composition (with some exceptions) unless they are re-opened at some later stage. Melt inclusions thus offer several key advantages over whole rock samples: (i) they record pristine concentrations of volatiles and metals that are usually lost during magma solidification and degassing, (ii) they are snapshots in time whereas whole rocks are the time-integrated end products, thus allowing a more detailed, time-resolved view into magmatic processes (iii) they are largely unaffected by subsolidus alteration. Due to these characteristics, melt inclusions are an ideal tool to study the evolution of mineralized magma systems. This chapter first discusses general aspects of melt inclusions formation and methods for their investigation, before reviewing studies performed on mineralized magma systems.

Video game addiction and college performance among males: results from a 1 year longitudinal study.

Science.gov (United States)

Schmitt, Zachary L; Livingston, Michael G

2015-01-01

This study explored the pattern of video game usage and video game addiction among male college students and examined how video game addiction was related to expectations of college engagement, college grade point average (GPA), and on-campus drug and alcohol violations. Participants were 477 male, first year students at a liberal arts college. In the week before the start of classes, participants were given two surveys: one of expected college engagement, and the second of video game usage, including a measure of video game addiction. Results suggested that video game addiction is (a) negatively correlated with expected college engagement, (b) negatively correlated with college GPA, even when controlling for high school GPA, and (c) negatively correlated with drug and alcohol violations that occurred during the first year in college. Results are discussed in terms of implications for male students' engagement and success in college, and in terms of the construct validity of video game addiction.

Performance in College Chemistry: a Statistical Comparison Using Gender and Jungian Personality Type

Science.gov (United States)

Greene, Susan V.; Wheeler, Henry R.; Riley, Wayne D.

This study sorted college introductory chemistry students by gender and Jungian personality type. It recognized differences from the general population distribution and statistically compared the students' grades with their Jungian personality types. Data from 577 female students indicated that ESFP (extroverted, sensory, feeling, perceiving) and ENFP (extroverted, intuitive, feeling, perceiving) profiles performed poorly at statistically significant levels when compared with the distribution of females enrolled in introductory chemistry. The comparable analysis using data from 422 male students indicated that the poorly performing male profiles were ISTP (introverted, sensory, thinking, perceiving) and ESTP (extroverted, sensory, thinking, perceiving). ESTJ (extroverted, sensory, thinking, judging) female students withdrew from the course at a statistically significant level. For both genders, INTJ (introverted, intuitive, thinking, judging) students were the best performers. By examining the documented characteristics of Jungian profiles that correspond with poorly performing students in chemistry, one may more effectively assist the learning process and the retention of these individuals in the fields of natural science, engineering, and technology.

Strategies to improve the performance of learners in a nursing college Part I: Issues pertaining to nursing education

Directory of Open Access Journals (Sweden)

E Waterson

2006-09-01

Full Text Available Three focus group interviews were conducted. One group was formed by seven tutors, and the other two groups were formed by fourth-year learners following a fouryear comprehensive diploma course. All participants voluntarily took part in the study. Data was analyzed using the descriptive method of open coding by Tesch (in Creswell, 1994:154-156. Trustworthiness was ensured in accordance with Lincoln and Guba’s (1985:290-326 principles of credibility, conformability, transferability and dependability. The findings were categorized into issues pertaining to nursing education as follows: curriculum overload; lack of theory and practice integration; teaching and assessment methods that do not promote critical thinking; tutors’ lack of skills and experience; inadequate preparation of tutors for lectures; insufficient knowledge of tutors regarding outcomes-based education approach to teaching and learning; inadequate process of remedial teaching; discrepancies between tutors’ marking; lack of clinical role-models and high expectations from the affiliated university as regards standards of nursing education in a nursing college. Strategies to improve the learners’ performance were described. It is recommended that these strategies be incorporated in the staff development programme by the staff development committee of the nursing college under study for implementation. Future research should focus on the effectiveness of the described strategies to improve the learners’ performance. It is also recommended that similar studies be conducted or replicated in other nursing colleges to address the problem of poor performance of learners engaged in a four-year comprehensive diploma course.

Full Text Available This retrospective study was carried out to assess the correlation between admi-ssion criteria to health science colleges, namely, final high school grade and Saudi National Apti-tude and Achievement exams, and early academic performance in these colleges. The study inclu-ded 91 male students studying in the two-year pre-professional program at the King Saud bin Abdulaziz University for Health Sciences (KSAU-HS, Riyadh, Saudi Arabia. Records of these students were used to extract relevant information and their academic performance (based on the grade point average achieved at the end of the first semester of the pre-professional program, which were analytically studied. Pearson correlation coefficient was used to assess the associa-tions between the different scores. SPSS statistical program (version 12.0 was used for data ana-lyses. We found a strong correlation between the academic performance and the Achievement Exam, Aptitude Exam and high school final grade, with Pearson Correlation Coefficients of 0.96, 0.93, 0.87, respectively. The Saudi National Achievement Exam showed the most significant correla-tion. Our results indicate that academic performance showed good correlation with the admission criteria used, namely final high school grade, Saudi National Aptitude and Achievement Exams.

The aim of this contextual, exploratory, descriptive and qualitative study was to describe strategies to improve the performance of learners in a nursing college. The article seeks to deal with factors relating to nursing education that contribute to the poor performance of learners and to outline related strategies to improve the situation. Three focus group interviews were conducted. One group was formed by seven tutors, and the other two groups were formed by fourth-year learners following a four-year comprehensive diploma course. All participants voluntarily took part in the study. Data was analyzed using the descriptive method of open coding by Tesch (in Creswell, 1994:154-156). Trustworthiness was ensured in accordance with Lincoln and Guba's (1985:290-326) principles of credibility, conformability, transferability and dependability. The findings were categorized into issues pertaining to nursing education as follows: curriculum overload; lack of theory and practice integration; teaching and assessment methods that do not promote critical thinking; tutors' lack of skills and experience; inadequate preparation of tutors for lectures; insufficient knowledge of tutors regarding outcomes-based education approach to teaching and learning; inadequate process of remedial teaching; discrepancies between tutors' marking; lack of clinical role-models and high expectations from the affiliated university as regards standards of nursing development programme by the staff development committee of the nursing college under study for implementation. Future research should focus on the effectiveness of the described strategies to improve the learners' performance. It is also recommended that similar studies be conducted or replicated in other nursing colleges to address the problem of poor performance of learners engaged in a four-year comprehensive diploma course.

Aimé, Annie; Villatte, Aude; Cyr, Caroline; Marcotte, Diane

2017-04-01

Over a third of American college students are either overweight or obese, which has been suggested to negatively impact their academic achievement. This study seeks to better understand the relationship between body mass index (BMI) and grade point average (GPA), while examining potential mediators of this association. The sample consists of 298 college women who volunteered to complete online questionnaires between October and December 2014. Although no significant differences were noted for sociodemographic variables, overweight and obese female students were found to report lower GPA and academic self-efficacy as well as higher depressive symptoms, compared with their normal-weight counterparts. Academic self-efficacy partially mediated the relationship between BMI and GPA. To foster better academic achievement in female college students, and especially for those who are overweight and obese, strategies for improving self-efficacy and adaptation to college should be implemented.

Full Text Available Alcohol and marijuana are the two most abused substances in US colleges. However, research on the combined influence (cross sectional or longitudinal of these substances on academic performance is currently scant.Data were derived from the longitudinal 2-year Brain and Alcohol Research in College Students (BARCS study including 1142 freshman students who completed monthly marijuana use and alcohol consumption surveys. Subjects were classified into data-driven groups based on their alcohol and marijuana consumption. A linear mixed-model (LMM was employed using this grouping factor to predict grade point average (GPA, adjusted for a variety of socio-demographic and clinical factors.Three data-driven clusters emerged: 1 No/low users of both, 2 medium-high alcohol/no-low marijuana, and 3 medium-high users of both substances. Individual cluster derivations between consecutive semesters remained stable. No significant interaction between clusters and semester (time was noted. Post-hoc analysis suggest that at the outset, compared to sober peers, students using moderate to high levels of alcohol and low marijuana demonstrate lower GPAs, but this difference becomes non-significant over time. In contrast, students consuming both substances at moderate-to-high levels score significantly lower at both the outset and across the 2-year investigation period. Our follow-up analysis also indicate that when students curtailed their substance use over time they had significantly higher academic GPA compared to those who remained stable in their substance use patterns over the two year period.Overall, our study validates and extends the current literature by providing important implications of concurrent alcohol and marijuana use on academic achievement in college.

Comparative analysis of a nontraditional general chemistry textbook and selected traditional textbooks used in Texas community colleges

Science.gov (United States)

Salvato, Steven Walter

The purpose of this study was to analyze questions within the chapters of a nontraditional general chemistry textbook and the four general chemistry textbooks most widely used by Texas community colleges in order to determine if the questions require higher- or lower-order thinking according to Bloom's taxonomy. The study employed quantitative methods. Bloom's taxonomy (Bloom, Engelhart, Furst, Hill, & Krathwohl, 1956) was utilized as the main instrument in the study. Additional tools were used to help classify the questions into the proper category of the taxonomy (McBeath, 1992; Metfessel, Michael, & Kirsner, 1969). The top four general chemistry textbooks used in Texas community colleges and Chemistry: A Project of the American Chemical Society (Bell et al., 2005) were analyzed during the fall semester of 2010 in order to categorize the questions within the chapters into one of the six levels of Bloom's taxonomy. Two coders were used to assess reliability. The data were analyzed using descriptive and inferential methods. The descriptive method involved calculation of the frequencies and percentages of coded questions from the books as belonging to the six categories of the taxonomy. Questions were dichotomized into higher- and lower-order thinking questions. The inferential methods involved chi-square tests of association to determine if there were statistically significant differences among the four traditional college general chemistry textbooks in the proportions of higher- and lower-order questions and if there were statistically significant differences between the nontraditional chemistry textbook and the four traditional general chemistry textbooks. Findings indicated statistically significant differences among the four textbooks frequently used in Texas community colleges in the number of higher- and lower-level questions. Statistically significant differences were also found among the four textbooks and the nontraditional textbook. After the analysis of

Early to bed, early to rise! Sleep habits and academic performance in college students.

Science.gov (United States)

Eliasson, Arne H; Lettieri, Christopher J; Eliasson, Arn H

2010-02-01

Prior studies have placed emphasis on the need for adequate total sleep time for student performance. We sought to investigate the relative importance of total sleep time compared to the timing of sleep and wakefulness for academic performance. We performed a questionnaire-based survey of college students in October 2007. The questionnaire gathered detailed information on sleep habits including naps, reasons for missing sleep, academic performance, study habits, time spent working outside of school, and stimulant use. Compared to those with the lowest academic performance, students with the highest performance had significantly earlier bedtimes (p = 0.05) and wake times (p = 0.008). Napping tended to be more common among high performers (p = 0.07). Of importance, there were no significant differences in total sleep time with or without naps, weekend sleep habits, study time, gender, race, reasons for staying up at night, nor in use of caffeinated beverages, over-the-counter stimulant pills, or use of prescription stimulants. Timing of sleep and wakefulness correlated more closely with academic performance than total sleep time and other relevant factors. These findings have important implications for programs intended to improve academic performance by targeting sleep habits of students.

Unmarried parents in college.

Science.gov (United States)

Goldrick-Rab, Sara; Sorensen, Kia

2010-01-01

Noting that access to higher education has expanded dramatically in the past several decades, Sara Goldrick-Rab and Kia Sorensen focus on how unmarried parents fare once they enter college. Contrary to the expectation that access to college consistently promotes family stability and economic security, the authors argue that deficiencies in current policy lead college attendance to have adverse consequences for some families headed by unmarried parents. Although rates of college attendance have increased substantially among unmarried parents, their college completion rates are low. One explanation is inadequate academic preparation. Another is financial constraints, which can force unmarried students to interrupt their studies or increase their work hours, both of which compromise the quality of their educational experiences and the outcomes for their children. The authors point out that although many public programs offer support to unmarried parents attending college, the support is neither well coordinated nor easily accessed. Over the past three decades, loans have increasingly replaced grants as the most common form of federal and state financial aid. Confusion about what is available leads many low-income students to the two most "straightforward" sources of income--loans and work, both of which involve significant costs and can operate at cross-purposes with public forms of support. Too much work can lead to reductions in public benefits, and earnings do not always replace the lost income. A growing body of experimental evidence shows that providing social, financial, and academic supports to vulnerable community college students can improve achievement and attainment. Contextualized learning programs, for example, have enabled participants not only to move on from basic skills to credit-bearing coursework, but also to complete credits, earn certificates, and make gains on basic skills tests. Another successful initiative provided low-performing students with

Cole, James S

2015-03-01

This study examines the relationships between circadian preference and caffeine use with academic performance and hours spent studying for recent high school graduates entering their first year of college. Entering first-year college students enrolled at 90 baccalaureate-level institutions across the USA were invited to complete the Beginning College Survey of Student Engagement (BCSSE) and the Composite Scale of Morningness (CSM) as well as answer questions regarding caffeine consumption. Surveys were administered on each campus during the summer months of 2013. Only those that graduated from a US high school in the spring of 2013 were included in this study. The final sample for this study included 25,200 students that completed the BCSSE, CSM, and questions regarding caffeine consumption. Evening types (E-types) were significantly less likely to report earning A/A-'s in high school and less likely to study 16 or more hours per week compared to intermediate or morning types (M-types) (p students reported an average of 1.1 servings of caffeine per day, with 39 % reporting no caffeine consumption. M-types were more likely to consume no caffeine (54 %) compared to E-types that also indicated no daily caffeine (31 %) (p amount (7 %) (p high school. However, the apparent advantage that morning types had over evening types regarding high school grades was completely ameliorated once three or more servings of caffeine were consumed per day. This study provides additional information to educators and health professionals to create programs and provide resource to help adolescents better understand the impact of their sleep behaviors and use of caffeine on their academic performance.

As the chapters in this book describe, the northern pike Esox lucius Linneaus, 1758 is a fascinating fish that plays an important ecological role in structuring aquatic communities (chapter 8), has the capacity to aid lake restoration efforts (chapter 11), and contributes substantially to local economies, both as a highlysought after sport fish (chapter 12) and as a commercial fishing resource (chapter 13). However, despite the magnificent attributes of this fish, there is another side to its story. Specifically, what happens when northern pike, a highly efficient predator, becomes established outside its natural range? To explore this question, this chapter will investigate observed consequences from many locations where northern pike (hereafter referred to as “pike”) have been introduced and discuss potential reasons why pike, under the right circumstances, can be considered an invasive species.

This chapter assesses palaeoclimatic data and knowledge of how the climate system changes over interannual to millennial time scales, and how well these variations can be simulated with climate models. Additional palaeoclimatic perspectives are included in other chapters. Palaeoclimate science has made significant advances since the 1970s, when a primary focus was on the origin of the ice ages, the possibility of an imminent future ice age, and the first explorations of the so-called Little Ice Age and Medieval Warm Period. Even in the first IPCC assessment, many climatic variations prior to the instrumental record were not that well known or understood. Fifteen years later, understanding is much improved, more quantitative and better integrated with respect to observations and modelling. After a brief overview of palaeoclimatic methods, including their strengths and weaknesses, this chapter examines the palaeoclimatic record in chronological order, from oldest to youngest. This approach was selected because the climate system varies and changes over all time scales, and it is instructive to understand the contributions that lower-frequency patterns of climate change might make in influencing higher-frequency patterns of variability and change. In addition, an examination of how the climate system has responded to large changes in climate forcing in the past is useful in assessing how the same climate system might respond to the large anticipated forcing changes in the future. Cutting across this chronologically based presentation are assessments of climate forcing and response, and of the ability of state-of-the-art climate models to simulate the responses. Perspectives from palaeoclimatic observations, theory and modelling are integrated wherever possible to reduce uncertainty in the assessment. Several sections also assess the latest developments in the rapidly advancing area of abrupt climate change, that is, forced or unforced climatic change that involves

Characteristics of sprint performance in college football players.

Science.gov (United States)

Brechue, William F; Mayhew, Jerry L; Piper, Fontaine C

2010-05-01

To investigate sprinting strategy, acceleration and velocity patterns were determined in college football players (n = 61) during performance of a 9.1-, 36.6-, and 54.9-m sprints. Acceleration and velocity were determined at 9.1-m intervals during each sprint. Lower-body strength and power were evaluated by 1 repetition maximum (1-RM) squat, power clean, jerk, vertical jump, standing long jump, and standing triple jump. Sprint times averaged 1.78 +/- 0.11 seconds (9.1 m), 5.18 +/- 0.35 seconds (36.6 m), and 7.40 +/- 0.53 seconds. Acceleration peaked at 9.1 m (2.96 +/- 0.44 m x s(-2)), was held constant at 18.3 m (3.55 +/- 0.0.94 m x s(-2)), and was negative at 27.4 m (-1.02 +/- 0.72 m x s(-2)). Velocity peaked at 18.3 m (8.38 +/- 0.65 m x s(-2)) and decreased slightly, but significantly at 27.4 m (7.55 +/- 0.66 m x s(-2)), associated with the negative acceleration. Measures of lower-body strength were significantly related to acceleration, velocity, and sprint performance only when corrected for body mass. Lower-body strength/BM and power correlated highest with 36.6-m time (rs = -0.55 to -0.80) and with acceleration (strength r = 0.67-0.49; power r = 0.73-0.81) and velocity (strength r = 0.68-0.53; power r = 0.74-0.82) at 9.1 m. Sprint times and strength per body mass were significantly lower in lineman compared with linebackers-tight ends and backs. The acceleration and velocity patterns were the same for each position group, and differences in sprint time were determined by the magnitude of acceleration and velocity at 9.1 and 18.3 m. Sprint performance in football players is determined by a rapid increase in acceleration (through 18.3 m) and a high velocity maintained throughout the sprint and is independent of position played. The best sprint performances (independent of sprint distance) appear to be related to the highest initial acceleration (through 18.3 m) and highest attained and maintained velocity. Strength relative to body mass and power appears to

Conceptual and procedural knowledge community college students use when solving a complex science problem

Science.gov (United States)

Steen-Eibensteiner, Janice Lee

2006-07-01

A strong science knowledge base and problem solving skills have always been highly valued for employment in the science industry. Skills currently needed for employment include being able to problem solve (Overtoom, 2000). Academia also recognizes the need for effectively teaching students to apply problem solving skills in clinical settings. This thesis investigates how students solve complex science problems in an academic setting in order to inform the development of problem solving skills for the workplace. Students' use of problem solving skills in the form of learned concepts and procedural knowledge was studied as students completed a problem that might come up in real life. Students were taking a community college sophomore biology course, Human Anatomy & Physiology II. The problem topic was negative feedback inhibition of the thyroid and parathyroid glands. The research questions answered were (1) How well do community college students use a complex of conceptual knowledge when solving a complex science problem? (2) What conceptual knowledge are community college students using correctly, incorrectly, or not using when solving a complex science problem? (3) What problem solving procedural knowledge are community college students using successfully, unsuccessfully, or not using when solving a complex science problem? From the whole class the high academic level participants performed at a mean of 72% correct on chapter test questions which was a low average to fair grade of C-. The middle and low academic participants both failed (F) the test questions (37% and 30% respectively); 29% (9/31) of the students show only a fair performance while 71% (22/31) fail. From the subset sample population of 2 students each from the high, middle, and low academic levels selected from the whole class 35% (8/23) of the concepts were used effectively, 22% (5/23) marginally, and 43% (10/23) poorly. Only 1 concept was used incorrectly by 3/6 of the students and identified as

Stereotype Threat and College Academic Performance: A Latent Variables Approach*

Science.gov (United States)

Owens, Jayanti; Massey, Douglas S.

2013-01-01

Stereotype threat theory has gained experimental and survey-based support in helping explain the academic underperformance of minority students at selective colleges and universities. Stereotype threat theory states that minority students underperform because of pressures created by negative stereotypes about their racial group. Past survey-based studies, however, are characterized by methodological inefficiencies and potential biases: key theoretical constructs have only been measured using summed indicators and predicted relationships modeled using ordinary least squares. Using the National Longitudinal Survey of Freshman, this study overcomes previous methodological shortcomings by developing a latent construct model of stereotype threat. Theoretical constructs and equations are estimated simultaneously from multiple indicators, yielding a more reliable, valid, and parsimonious test of key propositions. Findings additionally support the view that social stigma can indeed have strong negative effects on the academic performance of pejoratively stereotyped racial-minority group members, not only in laboratory settings, but also in the real world.

Why women perform better in college than admission scores would predict: Exploring the roles of conscientiousness and course-taking patterns.

Science.gov (United States)

Keiser, Heidi N; Sackett, Paul R; Kuncel, Nathan R; Brothen, Thomas

2016-04-01

Women typically obtain higher subsequent college GPAs than men with the same admissions test score. A common reaction is to attribute this to a flaw in the admissions test. We explore the possibility that this underprediction of women's performance reflects gender differences in conscientiousness and college course-taking patterns. In Study 1, we focus on using the ACT to predict performance in a single, large course where performance is decomposed into cognitive (exam and quiz scores) and less cognitive, discretionary components (discussion and extra credit points). The ACT does not underpredict female's cognitive performance, but it does underpredict female performance on the less cognitive, discretionary components of academic performance, because it fails to measure and account for the personality trait of conscientiousness. In Study 2, we create 2 course-difficulty indices (Course Challenge and Mean Aptitude in Course) and add them to an HLM regression model to see if they reduce the degree to which SAT scores underpredict female performance. Including Course Challenge does result in a modest reduction of the gender coefficient; however, including Mean Aptitude in Course does not. Thus, differences in course-taking patterns is a partial (albeit small) explanation for the common finding of differential prediction by gender. (c) 2016 APA, all rights reserved).

Is traditional financial aid too little, too late to help youth succeed in college? An introduction to The Degree Project promise scholarship experiment.

Science.gov (United States)

Harris, Douglas N

2013-01-01

One of the key barriers in accessing postsecondary opportunities for many students is financial aid. This chapter begins by providing a review of prior evidence on the relationship between financial aid and postsecondary outcomes. One type of financial aid intervention that challenges traditional aid and scholarship options are "promise programs." These programs make commitments to low-income students when they are much younger than when students typically apply for aid and have the potential to encourage students to better prepare during high school, develop the social capital they need to navigate the path to college, and pay for growing college costs. In this chapter, the author describes the design and rationale for The Degree Project (TDP), which is the first randomized trial of a promise scholarship in the United States. In addition to the important new evidence the demonstration program will generate, TDP also shows how educators and researchers can work together to provide the insight and answers policy makers need to address very real education gaps. © WILEY PERIODICALS, INC.

Nuclear Medicine Imaging Devices. Chapter 11

Energy Technology Data Exchange (ETDEWEB)

Lodge, M. A.; Frey, E. C. [Russell H. Morgan Department of Radiology and Radiological Sciences, Johns Hopkins University, Baltimore, MD (United States)

2014-12-15

Imaging forms an important part of nuclear medicine and a number of different imaging devices have been developed. This chapter describes the principles and technological characteristics of the main imaging devices used in nuclear medicine. The two major categories are gamma camera systems and positron emission tomography (PET) systems. The former are used to image γ rays emitted by any nuclide, while the latter exploit the directional correlation between annihilation photons emitted by positron decay. The first section of this chapter discusses the principal components of gamma cameras and how they are used to form 2-D planar images as well as 3-D tomographic images (single photon emission computed tomography (SPECT)). The second section describes related instrumentation that has been optimized for PET data acquisition. A major advance in nuclear medicine was achieved with the introduction of multi-modality imaging systems including SPECT/computed tomography (CT) and PET/CT. In these systems, the CT images can be used to provide an anatomical context for the functional nuclear medicine images and allow for attenuation compensation. The third section in this chapter provides a discussion of the principles of these devices.

Marijuana use, craving, and academic motivation and performance among college students: An in-the-moment study.

Science.gov (United States)

Phillips, Kristina T; Phillips, Michael M; Lalonde, Trent L; Tormohlen, Kayla N

2015-08-01

Marijuana is the most commonly used illicit substance in the U.S., with high rates among young adults in the state of Colorado. Chronic, heavy marijuana use can impact cognitive functioning, which has the potential to influence academic performance of college students. It is possible that craving for marijuana may further contribute to diminished cognitive and affective functioning, thus leading to poor outcomes for students. College student marijuana users (n=57) were recruited based on heavy use and completed ecological momentary assessment (EMA) via text-messaging. The association between marijuana use and craving in a college setting was explored, as well as how these variables might relate to academic motivation, effort and success. The participants were sent text messages for two weeks, three times per day at random times. A temporal association between craving and marijuana use was found, where momentary craving positively predicted greater marijuana use. Similarly, as craving levels increased, the number of minutes spent studying decreased at the next assessment point. A negative association between momentary craving for marijuana and academic motivation was found in the same moment. Greater academic self-efficacy positively predicted cumulative GPA, while average minutes spent smoking marijuana was negatively related. Using EMA, marijuana craving and use were significantly related. These findings provide further evidence that heavy marijuana use is negatively associated with academic outcomes.

The Accreditation Council for Graduate Medical Education requires scholarly activity within general surgery residency programs. The association between in-training research presentations and postgraduation publications is unknown. We hypothesized that surgical trainee presentations at an American College of Surgeons (ACS) state chapter meeting resulted in peer-reviewed publications and future scholarly activity. The ACS Wisconsin state chapter meeting agendas from 2000 to 2014 were reviewed to identify all trainees who delivered podium presentations. A literature search was completed for subsequent publications. Program coordinators were queried and an electronic search was performed to determine practice location and type for each residency graduate. Wisconsin state chapter ACS meeting. General surgery residents, fellows, and medical students in Wisconsin. There were 288 podium presentations by trainees (76% residents, 20% medical students, and 4% fellows). Presentations were clinical (79.5%) and basic science (20.5%). There were 204 unique presenters; 25% presented at subsequent meetings. Of these unique presenters, 46% published their research and 31% published additional research after residency. Among presenters who completed residency or fellowship (N = 119), 34% practiced in a university setting, and 61% practiced in a community setting; 31% practiced in Wisconsin. When comparing clinical vs basic science presenters, there was no difference in fellowship completion (37% vs 44%; p = 0.190) or practice type (38% vs 46% in a university setting; p = 0.397). Repeat presenters were more likely to pursue a fellowship vs those presenting once (76% vs 37%; p = 0.001). Research presentations by surgical trainees at an ACS state chapter meeting frequently led to peer-reviewed publications. Presenters were likely to pursue research opportunities after residency. Repeat presenters were more likely to pursue a fellowship. ACS Wisconsin chapter meetings provide an

Measurements of absorbed dose (or air kerma) are required in varying situations in diagnostic radiology. The radiation fields vary from plain, slit and even point projection geometry, and may be stationary or moving, including rotational. Owing to the use of low photon energies for these fields, it is important that dosimeters have a satisfactory energy response. In general, the requirements for dosimeter accuracy are less stringent than those in radiation therapy; however, the dose and dose rate measurements cover a large range. Patient dosimetry (see Chapter 22) is a primary responsibility of the medical physicist specializing in diagnostic radiology and is required by legislation in many countries. Dose data are also required in the optimization of examinations for image quality and dose. Radiation measurement is also critical for occupational and public exposure control (see Chapter 24). Dose measurements are essential in acceptance testing and quality control (see Chapter 19). Several types of dosimeter can be used, provided that they have a suitable energy response, but typically, ionization chambers of a few cubic centimetres in volume, or solid state detectors specifically designed for such measurements, are used. If dosimeters are used to make measurements during an examination, they must not interfere with the examination. These devices are also used for determination of the half value layer (HVL). Special types of ionization chamber are employed for computed tomography (CT), mammography and interventional radiology dosimetry.

The basic principles of radiation protection and their implementation as they apply to nuclear medicine are covered in general in Chapter 3. This chapter will look at the specific case of nuclear medicine used for therapy. In addition to the standards discussed in Chapter 3, specific guidance on the release of patients after radionuclide therapy can be found in the IAEA’s Safety Reports Series No. 63 [20.1]. When the patient is kept in hospital following radionuclide therapy, the people at risk of exposure include hospital staff whose duties may or may not directly involve the use of radiation. This can be a significant problem. However, it is generally felt that it can be effectively managed with well trained staff and appropriate facilities. On the other hand, once the patient has been released, the groups at risk include members of the patient’s family, including children, and carers; they may also include neighbours, visitors to the household, co-workers, those encountered in public places, on public transport or at public events, and finally, the general public. It is generally felt that these risks can be effectively mitigated by the radiation protection officer (RPO) with patient-specific radiation safety precaution instructions.

A Correlation of Community College Math Readiness and Student Success

Science.gov (United States)

Brown, Jayna Nicole

Although traditional college students are more prepared for college-level math based on college admissions tests, little data have been collected on nontraditional adult learners. The purpose of this study was to investigate relationships between math placement tests and community college students' success in math courses and persistence to degree or certificate completion. Guided by Tinto's theory of departure and student retention, the research questions addressed relationships and predictability of math Computer-adaptive Placement Assessment and Support System (COMPASS) test scores and students' performance in math courses, persistence in college, and degree completion. After conducting correlation and regression analyses, no significant relationships were identified between COMPASS Math test scores and students' performance (n = 234) in math courses, persistence in college, or degree completion. However, independent t test and chi-squared analyses of the achievements of college students who tested into Basic Math (n = 138) vs. Introduction to Algebra (n = 96) yielded statistically significant differences in persistence (p = .039), degree completion (p college students' math competencies and degree achievement.

This article forms part two of a bigger study that was conducted in a nursing college to explore and describe the reasons for the poor performance of learners. Part one of the study dealt with the issues pertaining to education, while this article (part two) seeks to describe issues pertaining to management, attitudes and values that lead to the poor performance of learners in the nursing college under study. A qualitative, exploratory and descriptive design that was contextual in nature was employed, and three focus groups interviews were conducted. Seven tutors formed one group while other two groups were formed by fourth-year learners following a comprehensive diploma course. All participants voluntarily participated in the study. Data was analyzed using the descriptive method of open coding in accordance with Tesch's protocol (in Creswell, 1994:154-156). Trustworthiness was ensured using the following principles: credibility, conformability, transferability and dependability (Lincoln & Guba 1985:290-326). Findings were categorized into issues pertaining to management, attitudes and values that had an influence on the poor performance of learners as follows: Inadequate resources and study facilities; policies that change frequently; tutors' dissatisfaction with regard to staff development, the lack of involvement by management and lack of management support, staff shortage and maldistribution of staff members; ineffective selection process of learners; inconsistent regulations, and too many of them; policies and procedures resulting in confusion and poor discipline. Attitudes and values: Tutors' lack of motivation and interest, lack of respect by learners and no team work among tutors. Through a conceptualization process and the recommendations by participants, strategies to improve the learners' performance were described. It is recommended that these strategies be submitted to the staff development committee for implementation and future follow-up research be

2012-01-01

Research tells us that academic preparation is key to deaf students' success at college. Yet, that is not the whole story. Many academically prepared students drop out during their first year. This study identified entering deaf college students' personal factors as assessed by their individual responses to both the Noel-Levitz College Student Inventory Form B and the Learning and Study Strategies Inventory, second edition (LASSI). Entering students in 3 successive cohorts (total n =437) participated in this study. Results show that in addition to entry measurements of reading and mathematic skills, personal factors contributed to the academic performance of students in their first quarter in college. The Noel-Levitz provided the comparatively better predictive value of academic performance: Motivation for Academic Study Scale (e.g., desire to finish college). The LASSI also showed statistically significant predictors, the Self-Regulation Component (e.g., time management) and Will Component (e.g., self-discipline), but accounted for relatively less variability in the students' initial grade point averages. For this group of underprepared students, results show that personal factors can play a significant role in academic success. Deaf students' personal factors are discussed as they relate to other first-year college students and to their subsequent academic performance and persistence.

This chapter discusses the hydrological and biogeochemical characteristics of Mirror Lake and the changes that resulted from air-land-water interactions and human activities. Since the formation of Mirror Lake, both the watershed and the lake have undergone many changes, such as vegetation development and basin filling. These changes are ongoing, and Mirror Lake is continuing along an aging pathway and ultimately, it will fill with sediment and no longer be a lake. The chapter also identifies major factors that affected the hydrology and biogeochemistry of Mirror Lake: acid rain, atmospheric deposition of lead and other heavy metals, increased human settlement around the lake, the construction of an interstate highway through the watershed of the Northeast Tributary, the construction of an access road through the West and Northeast watersheds to the lake, and climate change. The chapter also offers future recommendations for management and protection of Mirror Lake.

Deficient sleep is linked to detrimental outcomes in health and school performance for adolescents. This study characterized sleep patterns in Chinese adolescents preparing for the College Entrance Exam (CEE) and evaluated the association between sleep patterns, self-rated academic performance, and the CEE scores. A sample of 481 Chinese adolescents in 12th grade (ages 16-19 years) completed questionnaires about sleep patterns, academic performance, academic stress, and sociodemographic factors 4-6 weeks before the CEE in June 2013. The CEE scores for each student also were obtained. A total of 21% of the students had bedtimes after 12:00 am, 78.3% had sleep latency longer than 30 minutes, 14.6% had wake time earlier than 6:00 am, and the vast majority (94.4%) had sleep duration less than 8 hours. After adjusting for selected confounders such as academic stress, prolonged sleep latency was associated with poorer self-reported academic performance, and late bedtime was associated with higher CEE score. Our findings highlight the complex association between sleep and academic performance. Assessing and monitoring sleep patterns in adolescents during periods of high academic demand and stress may yield important recommendations for their health and safety as well as establishing optimal sleep and study habits. © 2016, American School Health Association.

Chemical Tracer Methods: Chapter 7

Science.gov (United States)

Healy, Richard W.

2017-01-01

Tracers have a wide variety of uses in hydrologic studies: providing quantitative or qualitative estimates of recharge, identifying sources of recharge, providing information on velocities and travel times of water movement, assessing the importance of preferential flow paths, providing information on hydrodynamic dispersion, and providing data for calibration of water flow and solute-transport models (Walker, 1998; Cook and Herczeg, 2000; Scanlon et al., 2002b). Tracers generally are ions, isotopes, or gases that move with water and that can be detected in the atmosphere, in surface waters, and in the subsurface. Heat also is transported by water; therefore, temperatures can be used to trace water movement. This chapter focuses on the use of chemical and isotopic tracers in the subsurface to estimate recharge. Tracer use in surface-water studies to determine groundwater discharge to streams is addressed in Chapter 4; the use of temperature as a tracer is described in Chapter 8.Following the nomenclature of Scanlon et al. (2002b), tracers are grouped into three categories: natural environmental tracers, historical tracers, and applied tracers. Natural environmental tracers are those that are transported to or created within the atmosphere under natural processes; these tracers are carried to the Earth’s surface as wet or dry atmospheric deposition. The most commonly used natural environmental tracer is chloride (Cl) (Allison and Hughes, 1978). Ocean water, through the process of evaporation, is the primary source of atmospheric Cl. Other tracers in this category include chlorine-36 (36Cl) and tritium (3H); these two isotopes are produced naturally in the Earth’s atmosphere; however, there are additional anthropogenic sources of them.

2017-01-01

This study aims to investigate the relationships among self-esteem, achievement goals, and self-handicapping and the potential mediating role of achievement goals in the relationship between self-esteem and self-handicapping in college physical education. The participants were 320 Chinese college students. Three validated scales were employed to assess participants' self-esteem, achievement goals, and self-handicapping in college physical education. Results showed that self-esteem had a negative effect on self-handicapping. Self-esteem had a positive effect on mastery goals, but had a negative effect on performance-avoidance goals. Mastery goals had a negative effect and performance-avoidance goals had a positive effect on self-handicapping. Moreover, mastery goals and performance-avoidance goals partially mediated the relationship between self-esteem and self-handicapping, and self-esteem had both direct and indirect effects on self-handicapping in college physical education. The findings indicate that improving individual's self-esteem and promoting mastery goals while reducing performance-avoidance goals may be relevant strategies to reduce self-handicapping in college physical education.

Chapter 29: Using an Existing Environment in the VO (IDL)

Science.gov (United States)

Miller, C. J.

The local environment of a Brightest Cluster Galaxy (BCG) can provide insight into the (still not understood) formation process of the BCG itself. BCGs are the most massive galaxies in the Universe, and their formation and evolution are a popular and current research topic (Linden et al. 2006, Bernardi et al. 2006, Lauer et al. 2006). They have been studied for some time (Sandage 1972, Ostriker & Tremaine 1975, White 1976, Thuan & Romanishin 1981, Merritt 1985, Postman and Lauer 1995, among many others). Our goal in this chapter is to study how the local environment can affect the physical and measurable properties of BCGs. We will conduct an exploratory research exercise. In this chapter, we will show how the Virtual Observatory (VO) can be effectively utilized for doing modern scientific research on BCGs. We identify the scientific functionalities we need, the datasets we require, and the service locations in order to discover and access those data. This chapter utilizes IDL's VOlib, which is described in Chapter 24 of this book and is available at http://www.nvo.noao.edu. IDL provides the capability to perform the entire range of astronomical scientific analyses in one environment: from image reduction and analysis to complex catalog manipulations, statistics, and publication quality figures. At the 2005 and 2006 NVO Summer Schools, user statistics show that IDL was the most commonly used programming language by the students (nearly 3-to-1 over languages like IRAF, Perl, and Python). In this chapter we show how the integration of IDL to the VO through VOlib provides even greater capabilities and possibilities for conducting science in the era of the Virtual Observatory. The reader should familiarize themselves with the VOlib libraries before attempting the examples in this tutorial. We first build a research plan. We then discover the service URLs we will need to access the data. We then apply the necessary functions and tools to these data before we can do our

Enhancing and Evaluating Scientific Argumentation in the Inquiryoriented College Chemistry Classroom

Science.gov (United States)

D'Souza, Annabel Nica

The research presented in chapters 2, 3, and 4 in this dissertation uses a sociocultural and sociohistorical lens, particularly around power, authority of knowledge and identity formation, to investigate the complexity of engaging in, supporting, and evaluating high-quality argumentation within a college biochemistry inquiry-oriented classroom. Argumentation skills are essential to college and career (National Research Council, 2010) and for a democratic citizenry. It is central to science teaching and learning (Osborne et al., 2004a) and can deepen content knowledge (Jimenez-Aleixandre et al., 2000; Jimenez-Aleixandre & Pereiro-Munhoz, 2002). When students have opportunities to make claims and support it with evidence and reasoning they may also increase their problem-solving and critical thinking capacity (Case, 2005; Willingham, 2007). Overall, this has implications in supporting students to become increasingly literate in scientific ideas, language, and practices. However, supporting argumentation can be challenging for instructors, particularly in designing leaning environments that facilitate and evaluate both the process and the product during student discussions (Duschl & Osborne, 2002). Fostering argumentation is complex and requires explicit modeling and multiple opportunities for dialogic interactions. This dissertation will examine how several facets influence argumentation in order to support instructors in implementing and improving argumentation in their inquiry-oriented classrooms. These facets include access to language and use of discursive moves, classroom design, curriculum and instructional activities, and interactional dynamics and power negotiation. The data set for this dissertation is a transcript generated from the audio- and video capture of a 7-minute student discussion around a mechanism in the TCA (TriCarboxylic Acid) cycle, as well as student writing, and course documents from student portfolios.

Unseen disadvantage: how American universities' focus on independence undermines the academic performance of first-generation college students.

Science.gov (United States)

Stephens, Nicole M; Fryberg, Stephanie A; Markus, Hazel Rose; Johnson, Camille S; Covarrubias, Rebecca

2012-06-01

American universities increasingly admit first-generation college students whose parents do not have 4-year degrees. Once admitted, these students tend to struggle academically, compared with continuing-generation students--students who have at least 1 parent with a 4-year degree. We propose a cultural mismatch theory that identifies 1 important source of this social class achievement gap. Four studies test the hypothesis that first-generation students underperform because interdependent norms from their mostly working-class backgrounds constitute a mismatch with middle-class independent norms prevalent in universities. First, assessing university cultural norms, surveys of university administrators revealed that American universities focus primarily on norms of independence. Second, identifying the hypothesized cultural mismatch, a longitudinal survey revealed that universities' focus on independence does not match first-generation students' relatively interdependent motives for attending college and that this cultural mismatch is associated with lower grades. Finally, 2 experiments at both private and public universities created a match or mismatch for first-generation students and examined the performance consequences. Together these studies revealed that representing the university culture in terms of independence (i.e., paving one's own paths) rendered academic tasks difficult and, thereby, undermined first-generation students' performance. Conversely, representing the university culture in terms of interdependence (i.e., being part of a community) reduced this sense of difficulty and eliminated the performance gap without adverse consequences for continuing-generation students. These studies address the urgent need to recognize cultural obstacles that contribute to the social class achievement gap and to develop interventions to address them. 2012 APA, all rights reserved

We examined compliance with performance measures for 14,464 patients enrolled from July 2008 through June 2009 into the American College of Cardiology's PINNACLE (Practice Innovation And Clinical Excellence) program to provide initial insights into the quality of outpatient cardiac care. Little is known about the quality of care of outpatients with coronary artery disease (CAD), heart failure, and atrial fibrillation, and whether sex and racial disparities exist in the treatment of outpatients. The PINNACLE program is the first, national, prospective office-based quality improvement program of cardiac patients designed, in part, to capture, report, and improve outpatient performance measure compliance. We examined the proportion of patients whose care was compliant with established American College of Cardiology, American Heart Association, and American Medical Association-Physician Consortium for Performance Improvement (ACC/AHA/PCPI) performance measures for CAD, heart failure, and atrial fibrillation. There were 14,464 unique patients enrolled from 27 U.S. practices, accounting for 18,021 clinical visits. Of these, 8,132 (56.4%) had CAD, 5,012 (34.7%) had heart failure, and 2,786 (19.3%) had nonvalvular atrial fibrillation. Data from the PINNACLE program were feasibly collected for 24 of 25 ACC/AHA/PCPI performance measures. Compliance with performance measures ranged from being very low (e.g., 13.3% of CAD patients screened for diabetes mellitus) to very high (e.g., 96.7% of heart failure patients with blood pressure assessments), with moderate (70% to 90%) compliance observed for most performance measures. For 3 performance measures, there were small differences in compliance rates by race or sex. For more than 14,000 patients enrolled from 27 practices in the outpatient PINNACLE program, we found that compliance with performance measures was variable, even after accounting for exclusion criteria, suggesting an important opportunity to improve the quality of

Part one of the study dealt with the issues pertaining to education, while this article (part two seeks to describe issues pertaining to management, attitudes and values that lead to the poor performance of learners in the nursing college under study. A qualitative, exploratory and descriptive design that was contextual in nature was employed, and three focus groups interviews were conducted. Seven tutors formed one group while other two groups were formed by fourth-year learners following a comprehensive diploma course. All participants voluntarily participated in the study. Data was analyzed using the descriptive method of open coding in accordance with Tesch’s protocol (in Creswell, 1994:154-156. Trustworthiness was ensured using the following principles: credibility, conformability, transferability and dependability (Lincoln & Guba 1985:290-326. Findings were categorized into issues pertaining to management, attitudes and values that had an influence on the poor performance of learners as follows: Management: Inadequate resources and study facilities; policies that change frequently; tutors’ dissatisfaction with regard to staff development, the lack of involvement by management and lack of management support, staff shortage and maldistribution of staff members; ineffective selection process of learners; inconsistent regulations, and too many of them; policies and procedures resulting in confusion and poor discipline. Attitudes and values: Tutors’ lack of motivation and interest, lack of respect by learners and no team work among tutors.Through a conceptualization process and the recommendations by participants, strategies to improve the learners’ performance were described. It is recommended that these strategies be submitted to the staff development committee for

The technologies used in nuclear medicine for diagnostic imaging have evolved over the last century, starting with Röntgen’s discovery of X rays and Becquerel’s discovery of natural radioactivity. Each decade has brought innovation in the form of new equipment, techniques, radiopharmaceuticals, advances in radionuclide production and, ultimately, better patient care. All such technologies have been developed and can only be practised safely with a clear understanding of the behaviour and principles of radiation sources and radiation detection. These central concepts of basic radiation physics and nuclear physics are described in this chapter and should provide the requisite knowledge for a more in depth understanding of the modern nuclear medicine technology discussed in subsequent chapters.

Soares, Ana Paula; Guisande, M Adelina; Diniz, António M; Almeida, Leandro S

2006-05-01

This article presents a model of interaction of personal and contextual variables in the prediction of academic performance and psychosocial development of Portuguese college students. The sample consists of 560 first-year college students of the University of Minho. The path analysis results suggest that initial expectations of the students' involvement in academic life constituted an effective predictor of their involvement during their first year; as well as the social climate of the classroom influenced their involvement, well-being and levels of satisfaction obtained. However, these relationships were not strong enough to influence the criterion variables integrated in the model (academic performance and psychosocial development). Academic performance was predicted by the high school grades and college entrance examination scores, and the level of psychosocial development was determined by the level of development showed at the time they entered college. Though more research is needed, these results point to the importance of students' pre-college characteristics when we are considering the quality of their college adjustment process.

Ross, B. (ed.)

1989-02-01

This report is intended as an overview of post-closure performance assessment methods for high-level radioactive waste repositories and is designed to give the reader a broad sense of the state of the art of this technology. As described here, ''the state of the art'' includes only what has been reported in report, journal, and conference proceedings literature through August 1987. There is a very large literature on the performance of high-level waste repositories. In order to make a review of this breadth manageable, its scope must be carefully defined. The essential principle followed is that only methods of calculating the long-term performance of waste repositories are described. The report is organized to reflect, in a generalized way, the logical order to steps that would be taken in a typical performance assessment. Chapter 2 describes ways of identifying scenarios and estimating their probabilities. Chapter 3 presents models used to determine the physical and chemical environment of a repository, including models of heat transfer, radiation, geochemistry, rock mechanics, brine migration, radiation effects on chemistry, and coupled processes. The next two chapters address the performance of specific barriers to release of radioactivity. Chapter 4 treats engineered barriers, including containers, waste forms, backfills around waste packages, shaft and borehole seals, and repository design features. Chapter 5 discusses natural barriers, including ground water systems and stability of salt formations. The final chapters address optics of general applicability to performance assessment models. Methods of sensitivity and uncertainty analysis are described in Chapter 6, and natural analogues of repositories are treated in Chapter 7. 473 refs., 19 figs., 2 tabs.

Reducing gender differences in performance in introductory college physics through values affirmation

Science.gov (United States)

Kost-Smith, Lauren

2011-04-01

Despite males and females being equally represented at the college level in several STEM disciplines (including biology, chemistry and mathematics), females continue to be under-represented in physics. Our research documents and addresses this participation gender gap in the introductory, calculus-based physics courses at the University of Colorado. We characterize gender differences in performance, psychological factors (including attitudes and beliefs) and retention that exist in Physics 1 and 2 [L. E. Kost, et al., Phys. Rev. ST Phys. Educ. Res. 5, 010101 (2009); L. E. Kost-Smith, et al., Phys. Rev. ST Phys. Educ. Res. 6, 020112 (2010)]. We find that the gender differences in performance can largely be accounted for by measurable differences in the physics and mathematics backgrounds and incoming attitudes and beliefs of males and females. But these background factors do not completely account for the gender gaps. We hypothesize, based on gender differences in responses to survey questions about students' sense of physics identity and confidence levels, that identity threat (the fear of confirming a negative characterization about one's identity) is playing a role in our courses. Working with researchers in psychology, we implemented an intervention where students either wrote about their most important values or not, twice at the beginning of the course [A. Miyake, et al., Science, 330, 1234 (2010)]. This ``values affirmation'' activity reduced the male-female performance difference substantially and elevated women's modal grades from the C to B range. Benefits were strongest for women who tended to endorse the stereotype that men do better than women in physics. This brief psychological intervention may be a promising way to address the gender gap in science performance.

Termos, Mohamad Hani

2011-12-01

The Classroom Performance System (CPS) is an instructional technology tool that increases student performance and addresses different learning styles. Instructional technologies are used to promote active learning; however, student embarrassment issue in a multicultural setting is not addressed. This study assessed the effect of the CPS on student participation, attendance, and achievement in multicultural college-level anatomy and physiology classes at South Texas College, where the first spoken language is not English. Quantitative method and quasi-experimental design were employed and comparative statistic methods and pre-post tests were used to collect the data. Participants were college students and sections of study were selected by convenient sampling. Participation was 100% during most of the lectures held and participation rate did not strike above 68% in control group. Attendance was significantly higher in CPS sections than the control group as shown by t-tests. Experimental sections had a higher increase in the pre-post test scores and student averages on lecture exams increased at a higher rate as compared to the control group. Therefore, the CPS increased student participation, attendance, and achievement in multicultural anatomy and physiology classes. The CPS can be studied in other settings where the first spoken language is English or in other programs, such as special education programs. Additionally, other variables can be studied and other methodologies can be employed.

Environmental monitoring guidance for DOE Order 5820.2A, Chapter 3

International Nuclear Information System (INIS)

Dolenc, M.R.

1988-01-01

The Defense Low-Level Waste Management Program (DLLWMP) is preparing guidance to support the requirements outlined in DOE Order 5820.2A, Chapter 3, Management of Low-Level Waste. One of these documents is the Environmental Monitoring Guidance. Environmental monitoring is required for all operational and nonoperational treatment, storage, and disposal facilities to ensure that the facility conforms to all appropriate DOE orders. An adequate environmental monitoring program must be designed to measure key parameters that may affect both short- and long-term site performance. These parameters include measuring both chemical and radiological releases in surface soil, air, surface water, flora, fauna, and subsurface soil and groundwater, both in the saturated and unsaturated zones. The monitoring program must be capable of detecting performance trends in sufficient time to allow corrective action before the facility exceeds performance objectives. The program should also provide the data input necessary to evaluate the performance assessment of the facility. This paper outlines the approach being planned to accomplish these tasks

Wadsworth, Andrew

2017-11-08

The field of organic photovoltaics has advanced a great deal over the last decade, with device efficiencies now exceeding 11%. A large part of this success can be attributed to the development of donor polymer materials, from their humble beginnings as homopolymers to the highly tuned push-pull copolymer and terpolymer materials that are now being reported on a regular basis. Through the careful use of chemical modification, it has been possible to design and synthesize a wide variety of donor polymers, allowing optimization of both the optoelectronic and structural properties of the materials. In doing so, more favourable active layer blends have been achieved and therefore significant improvements in device performance have been observed. Herein we discuss how the chemical design of donor polymers for organic photovoltaics has led to the emergence of high-performance materials.

Surface water quality in streams and rivers: introduction, scaling, and climate change: Chapter 5

Science.gov (United States)

Loperfido, John

2013-01-01

A variety of competing and complementary needs such as ecological health, human consumption, transportation, recreation, and economic value make management and protection of water resources in riverine environments essential. Thus, an understanding of the complex and interacting factors that dictate riverine water quality is essential in empowering stake-holders to make informed management decisions (see Chapter 1.15 for additional information on water resource management). Driven by natural and anthropogenic forcing factors, a variety of chemical, physical, and biological processes dictate riverine water quality, resulting in temporal and spatial patterns and cycling (see Chapter 1.2 for information describing how global change interacts with water resources). Furthermore, changes in climatic forcing factors may lead to long-term deviations in water quality outside the envelope of historical data. The goal of this chapter is to present fundamental concepts dictating the conditions of basic water quality parameters in rivers and streams (herein generally referred to as rivers unless discussing a specific system) in the context of temporal (diel (24 h) to decadal) longitudinal scaling. Understanding water quality scaling in rivers is imperative as water is continually reused and recycled (see also Chapters 3.1 and 3.15); upstream discharges from anthropogenic sources are incorporated into bulk riverine water quality that is used by downstream consumers. Water quality parameters reviewed here include temperature, pH, dissolved oxygen (DO), and suspended sediment and were selected given the abundance of data available for these parameters due to recent advances in water quality sensor technology (see Chapter 4.13 for use of hydrologic data in watershed management). General equations describing reactions affecting water temperature, pH, DO, and suspended sediment are included to convey the complexity of how simultaneously occurring reactions can affect water quality

CHAPTER 7. BERYLLIUM ANALYSIS BY NON-PLASMA BASED METHODS

It is the position of the American Dietetic Association, Dietitians of Canada, and the American College of Sports Medicine that physical activity, athletic performance, and recovery from exercise are enhanced by optimal nutrition. These organizations recommend appropriate selection of foods and fluids, timing of intake, and supplement choices for optimal health and exercise performance. This updated position paper couples a rigorous, systematic, evidence-based analysis of nutrition and performance-specific literature with current scientific data related to energy needs, assessment of body composition, strategies for weight change, nutrient and fluid needs, special nutrient needs during training and competition, the use of supplements and ergogenic aids, nutrition recommendations for vegetarian athletes, and the roles and responsibilities of the sports dietitian. Energy and macronutrient needs, especially carbohydrate and protein, must be met during times of high physical activity to maintain body weight, replenish glycogen stores, and provide adequate protein to build and repair tissue. Fat intake should be sufficient to provide the essential fatty acids and fat-soluble vitamins and to contribute energy for weight maintenance. Although exercise performance can be affected by body weight and composition, these physical measures should not be a criterion for sports performance and daily weigh-ins are discouraged. Adequate food and fluid should be consumed before, during, and after exercise to help maintain blood glucose concentration during exercise, maximize exercise performance, and improve recovery time. Athletes should be well hydrated before exercise and drink enough fluid during and after exercise to balance fluid losses. Sports beverages containing carbohydrates and electrolytes may be consumed before, during, and after exercise to help maintain blood glucose concentration, provide fuel for muscles, and decrease risk of dehydration and hyponatremia.

International Nuclear Information System (INIS)

1984-08-01

This document presents the preliminary plans and anticipated methods of the Salt Repository Project (SRP) for assessing the postclosure and radiological aspects of preclosure performance of a nuclear waste repository in salt. This plan is intended to be revised on an annual basis. The emphasis in this preliminary effort is on the method of conceptually dividing the system into three subsystems (the very near field, the near field, and the far field) and applying models to analyze the behavior of each subsystem and its individual components. The next revision will contain more detailed plans being developed as part of Site Characterization Plan (SCP) activities. After a brief system description, this plan presents the performance targets which have been established for nuclear waste repositories by regulatory agencies (Chapter 3). The SRP approach to modeling, including sensitivity and uncertainty techniques is then presented (Chapter 4). This is followed by a discussion of scenario analysis (Chapter 5), a presentation of preliminary data needs as anticipated by the SRP (Chapter 6), and a presentation of the SRP approach to postclosure assessment of the very near field, the near field, and the far field (Chapters 7, 8, and 9, respectively). Preclosure radiological assessment is discussed in Chapter 10. Chapter 11 presents the SRP approach to code verification and validation. Finally, the Appendix lists all computer codes anticipated for use in performance assessments. The list of codes will be updated as plans are revised

Full Text Available Periods of intense training can elicit an acute decline in performance and body composition associated with weakened hormone profiles. This study investigated the effects of a multi-ingredient performance supplement (MIPS on body composition and hormone levels in college athletes following a six-week training protocol. Twenty male college athletes were equally assigned to MIPS and placebo (PLA groups for supplementation (three pills, twice daily in conjunction with resistance training and specialized sports training (e.g., nine total sessions/week for six weeks. Dual Energy X-ray Absorptiometry determined body composition at weeks 0 and 6. Serum samples collected at weeks 0 and 6 determined free testosterone (FT, total testosterone (TT, IGF-1 and total estrogen (TE levels. PLA experienced a significant decline in lean body mass (LBM (−1.5 kg; p < 0.05 whereas the MIPS sustained LBM. The MIPS increased TT 21.9% (541.5 ± 48.7 to 639.1 ± 31.7 and increased FT 15.2% (13.28 ± 1.1 to 15.45 ± 1.3 ng/dL (p < 0.05. Conversely, PLA decreased TT 7.9% (554.5 ± 43.3 to 497.2 ± 39.1 ng/dL, decreased FT 17.4% (13.41 ± 1.8 to 11.23 ± 2.55 ng/dL, and decreased FT:E 12.06% (p < 0.05. These findings suggest the MIPS can prevent decrements in LBM and anabolic hormone profiles during intense training periods.

Care of the college student.

Unwin, Brian K; Goodie, Jeffrey; Reamy, Brian V; Quinlan, Jeffrey

2013-11-01

There are approximately 20 million students in U.S. colleges and universities. Although this population is characterized as having good health, 600,000 students report some form of disability or some type of medical problem, including attention-deficit/hyperactivity disorder, learning disabilities, psychiatric disorders, and chronic illnesses, among others. Physicians can enhance youth transition to an adult model of health care; the use of self-care skills checklists is one recommended method to assist with the transition. Stimulant medications are effective for treating adults with attention-deficit/hyperactivity disorder, but physicians should use caution when prescribing stimulants to college students because of the high rates of medication diversion in this population. Depression, anxiety, posttraumatic stress disorder, sleep problems, and eating disorders are common in college students and can significantly impact performance. Emphasis on immunization of students for influenza, meningococcus, and pertussis is necessary because of the low rates of compliance. Screening and interventions for obesity, tobacco use, and substance abuse are important because of the high prevalence of these problems in college students. Screening for alcohol abuse facilitates identification of students with problem drinking behaviors. Students who are war veterans should be monitored for suicidal ideation and posttraumatic stress disorder. Lesbian, gay, bisexual, transgender, and questioning students are at risk of harassment and discrimination. Caution should be exercised when prescribing medications to college athletes to avoid violation of National Collegiate Athletic Association eligibility rules.

Same-Sex Sexuality and Educational Attainment: The Pathway to College.

Science.gov (United States)

Pearson, Jennifer; Wilkinson, Lindsey

2017-01-01

Research finds lower levels of academic performance among sexual minority high school students, but some studies suggest sexual minorities have higher levels of educational attainment in adulthood. To further our understanding of how and why sexual orientation is associated with educational success, this study turns attention to the pathways to college completion, examining points along educational trajectories in which sexual minorities fall behind or surpass their heterosexual peers. Using data from the National Longitudinal Study of Adolescent to Adult Health, we find that sexual minority women are less likely than women with no same-sex sexuality to complete college, in part due to their high school performance and transition into college. Men who experience same-sex sexuality only in adolescence struggle in high school, but men who experience same-sex sexuality for the first time in adulthood are more likely to earn a college degree than men who do not experience same-sex sexuality.

On reforming chapter VI of the Euratom Treaty

International Nuclear Information System (INIS)

Sandtner, W.

1984-01-01

The supply of uranium to the countries of the EC has been provided for in Chapter VI of the European Treaty. An Euratom Supply Agency was created, which enjoys a monopoly. However, this arrangement was hardly ever utilized in practice. For this reason, several attempts were made in the course of time to reform Chapter VI, most recently in 1979 on the initiative of France. The EC Commission now presented a ''new nuclear power strategy'' in early 1982, which was followed by a detailed report about the proposed changes in late 1982. Its main points as outlined and discussed in this article are these: defining the range of application; the unity of the market; international relations; solidarity measures; the future role of the Supply Agency.

Electronics Related to Nuclear Medicine Imaging Devices. Chapter 7

Energy Technology Data Exchange (ETDEWEB)

Ott, R. J. [Joint Department of Physics, Royal Marsden Hospital and Institute of Cancer Research, Surrey (United Kingdom); Stephenson, R. [Rutherford Appleton Laboratory, Oxfordshire (United Kingdom)

2014-12-15

Nuclear medicine imaging is generally based on the detection of X rays and γ rays emitted by radionuclides injected into a patient. In the previous chapter, the methods used to detect these photons were described, based most commonly on a scintillation counter although there are imaging devices that use either gas filled ionization detectors or semiconductors. Whatever device is used, nuclear medicine images are produced from a very limited number of photons, due mainly to the level of radioactivity that can be safely injected into a patient. Hence, nuclear medicine images are usually made from many orders of magnitude fewer photons than X ray computed tomography (CT) images, for example. However, as the information produced is essentially functional in nature compared to the anatomical detail of CT, the apparently poorer image quality is overcome by the nature of the information produced. The low levels of photons detected in nuclear medicine means that photon counting can be performed. Here each photon is detected and analysed individually, which is especially valuable, for example, in enabling scattered photons to be rejected. This is in contrast to X ray imaging where images are produced by integrating the flux entering the detectors. Photon counting, however, places a heavy burden on the electronics used for nuclear medicine imaging in terms of electronic noise and stability. This chapter will discuss how the signals produced in the primary photon detection process can be converted into pulses providing spatial, energy and timing information, and how this information is used to produce both qualitative and quantitative images.

PERFORMANCE ASSESSMENT FOR FIELD SPORTS

Directory of Open Access Journals (Sweden)

Christopher Carling

2009-03-01

Full Text Available DESCRIPTION The book covers the various sport science assessment procedures for sports such as soccer, rugby, field hockey and lacrosse. It provides detailed and clear information about laboratory and field-based methods that can be used to assess and improve both individual and team performance. PURPOSE The book aims to provide a contemporary reference tool for selection of appropriate testing procedures for sports across a range of scientific disciplines. FEATURES The text begins with a chapter on the rationales for performance assessments, the use of technology and the necessity for procedures to conform to scientific rigor, explaining the importance of test criteria. This chapter ends by emphasizing the importance of the feedback process and vital considerations for the practitioner when interpreting the data, selecting which information is most important and how to deliver this back to the athlete or coach in order to deliver a positive performance outcome. The next two chapters focus on psychological assessments with respect to skill acquisition, retention and execution providing a variety of qualitative and quantitative options, underpinned with scientific theory and contextualized in order to improve the understanding of the application of these methods to improve anticipation and decision-making to enhance game intelligence.Chapter 4 provides coverage of match analysis techniques in order to make assessments of technical, tactical and physical performances. Readers learn about a series of methodologies ranging from simplistic pen and paper options through to sophisticated technological systems with some exemplar data also provided. Chapters 5 through 7 cover the physiological based assessments, including aerobic, anaerobic and anthropometric procedures. Each chapter delivers a theoretical opening section before progressing to various assessment options and the authors make great efforts to relate to sport-specific settings. The final

Algorithmic, LOCS and HOCS (chemistry) exam questions: performance and attitudes of college students

Zoller, Uri

2002-02-01

The performance of freshmen biology and physics-mathematics majors and chemistry majors as well as pre- and in-service chemistry teachers in two Israeli universities on algorithmic (ALG), lower-order cognitive skills (LOCS), and higher-order cognitive skills (HOCS) chemistry exam questions were studied. The driving force for the study was an interest in moving science and chemistry instruction from an algorithmic and factual recall orientation dominated by LOCS, to a decision-making, problem-solving and critical system thinking approach, dominated by HOCS. College students' responses to the specially designed ALG, LOCS and HOCS chemistry exam questions were scored and analysed for differences and correlation between the performance means within and across universities by the questions' category. This was followed by a combined student interview - 'speaking aloud' problem solving session for assessing the thinking processes involved in solving these types of questions and the students' attitudes towards them. The main findings were: (1) students in both universities performed consistently in each of the three categories in the order of ALG > LOCS > HOCS; their 'ideological' preference, was HOCS > algorithmic/LOCS, - referred to as 'computational questions', but their pragmatic preference was the reverse; (2) success on algorithmic/LOCS does not imply success on HOCS questions; algorithmic questions constitute a category on its own as far as students success in solving them is concerned. Our study and its results support the effort being made, worldwide, to integrate HOCS-fostering teaching and assessment strategies and, to develop HOCS-oriented science-technology-environment-society (STES)-type curricula within science and chemistry education.

2018-04-01

This chapter of the Gaia DR2 documentation describes the models and processing steps used for the astrometric core solution, namely, the Astrometric Global Iterative Solution (AGIS). The inputs to this solution rely heavily on the basic observables (or astrometric elementaries) which have been pre-processed and discussed in Chapter 2, the results of which were published in Fabricius et al. (2016). The models consist of reference systems and time scales; assumed linear stellar motion and relativistic light deflection; in addition to fundamental constants and the transformation of coordinate systems. Higher level inputs such as: planetary and solar system ephemeris; Gaia tracking and orbit information; initial quasar catalogues and BAM data are all needed for the processing described here. The astrometric calibration models are outlined followed by the details processing steps which give AGIS its name. We also present a basic quality assessment and validation of the scientific results (for details, see Lindegren et al. 2018).

Burnett, David M; Vardiman, John P; Deckert, Jake A; Ward, Jaimie L; Sharpe, Matthew R

2016-07-01

Exercise-induced bronchoconstriction (EIB) can lead to long-term respiratory illness and even death. EIB prevalence rates are both high and variable in college athletes. Also, prevalence rates may be underestimated due to ineffective screening. The purpose of this study is to investigate the prevalence of EIB and the perceived impact of EIB in college athletes via a self-report questionnaire. A self-report EIB questionnaire was administered to college athletes on 8 different sports teams. Information collected was used to identify athletes who self-reported: (1) a history of EIB and/or asthma, (2) respiratory symptoms during exercise, (3) medication use, and (4) concern about EIB. Results showed that 56 of 196 athletes (28.6%) self-reported a history of EIB or asthma. Over half (52%) reported a history of EIB/asthma or current EIB symptoms. Forty-six of the 140 athletes (32.9%) who did not report a history of EIB or asthma indicated symptoms of EIB during sports, training, or exercise. Fourteen of 56 athletes (25%) self-reporting a history of EIB or asthma did not report the use of a respiratory medication. Nineteen of 196 athletes (9.7%) reported being concerned that EIB was adversely affecting their sports performance. College athletes self-report a high prevalence of EIB or asthma. Although college athletes may not report a history of EIB or asthma, they indicate symptoms of EIB. A majority of athletes reported a history or current symptoms related to EIB or asthma. Many athletes with a history of EIB or asthma are not taking any asthma medication. Last, athletes report concern about EIB adversely affecting their sports performance. More work is needed using a combination of a screening questionnaire and standardized EIB testing to develop a validated tool for accurately screening and diagnosing EIB in college athletes.

2004-05-01

Full Text Available This study was conducted to determine whether states with performance budgeting and funding (PBF programs had improved institutional performance of higher education over the five years (1997 through 2001 considered in this study. First Time in College (FTIC graduation rate was used as the measure of institutional performance. In this study, the unit of analysis is institution level and the study population is all public four-or-more-year institutions in the United States. To test PBF program effectiveness, Hierarchical Linear Modeling (HLM growth analysis was applied. According to the HLM analysis, the growth of graduation rates in states with PBF programs was not greater than in states without PBF programs. The lack of growth in institutional graduation rates, however, does not mean that PBF programs failed to achieve their goals. Policy-makers are advised to sustain PBF programs long enough until such programs bear their fruits or are proven ineffective.

Since the role of emotional intelligence (EI) in achieving academic excellence requires further research, the aims of this cross-sectional study were to assess EI and its associated factors and to determine any association between EI and academic performance among final-year dental students in Bengaluru, India. In 2015, 208 dental students from six dental colleges in Bengaluru were invited to participate in the study. Their demographic and lifestyle data were collected, and EI was assessed with the 30-item Emotional Quotient Self-Assessment Checklist developed by Sterrett. Academic performance was assessed using grades obtained in the final-year undergraduate examination. The response rate was 96% (N=200). Overall, 54.5% of the participants had high EI scores (≥120), although only 51 (25.5%) had a high EI score in all the domains (≥20). EI was significantly greater in females than males. Gender, sleep, meeting friends, physical exercise, recreational activities, and academic performance were significantly associated with EI and accounted for 42% variance in hierarchical regression analysis. EI was also positively associated with academic performance. Gender and healthy lifestyle habits were positively associated with EI, which in turn influenced these students' academic performance. These findings suggest a possible need for attention to developing dental students' EI.

2017-01-01

This study aimed to examine potential differences in walking, cycling, public transport and passive transport (car/moped/motorcycle) to work and to other destinations between college and non-college educated working young adults. Secondly, we aimed to investigate which psychosocial and environmental factors are associated with the four transport modes and whether these associations differ between college and non-college educated working young adults. In this cross-sectional study, 224 working young adults completed an online questionnaire assessing socio-demographic variables (8 items), psychosocial variables (6 items), environmental variables (10 items) and transport mode (4 types) and duration to work/other destinations. Zero-inflated negative binomial regression models were performed in R. A trend (pyoung adults participated in cycling and public transport. However, another trend indicated that cycle time and public transport trips were longer and passive transport trips were shorter in non-college compared to college educated working young adults. In all working young adults, high self-efficacy towards active transport, and high perceived benefits and low perceived barriers towards active and public transport were related to more active and public transport. High social support/norm/modeling towards active, public and passive transport was related to more active, public and passive transport. High neighborhood walkability was related to more walking and less passive transport. Only in non-college educated working young adults, feeling safe from traffic and crime in their neighborhood was related to more active and public transport and less passive transport. Educational levels should be taken into account when promoting healthy transport behaviors in working young adults. Among non-college educated working young adults, focus should be on increasing active and public transport participation and on increasing neighborhood safety to increase active and public

Fox, Annie Beth; Rosen, Jonathan; Crawford, Mary

2009-02-01

Instant messaging (IM) has become one of the most popular forms of computer-mediated communication (CMC) and is especially prevalent on college campuses. Previous research suggests that IM users often multitask while conversing online. To date, no one has yet examined the cognitive effect of concurrent IM use. Participants in the present study (N = 69) completed a reading comprehension task uninterrupted or while concurrently holding an IM conversation. Participants who IMed while performing the reading task took significantly longer to complete the task, indicating that concurrent IM use negatively affects efficiency. Concurrent IM use did not affect reading comprehension scores. Additional analyses revealed that the more time participants reported spending on IM, the lower their reading comprehension scores. Finally, we found that the more time participants reported spending on IM, the lower their self-reported GPA. Implications and future directions are discussed.

Animation-Based Teaching of Semiconductor Devices: Long-Term Improvement in Students’ Achievements in a Two-Year College

Directory of Open Access Journals (Sweden)

Aharon Gero

2015-02-01

Full Text Available The structure and operating principle of semiconductor devices are a central topic in teaching electronics, both in universities and in two-year colleges. Teachers teaching this subject normally run into substantial difficulties stemming from the fact that a major part of the concepts and processes that are relevant to understanding these devices are abstract. In light of the advantages of multimedia in illustrating dynamic processes, the chapter covering the field effect transistor (FET has recently been taught through animation at a two-year college in Israel. The study presented here has examined, through quantitative tools, whether animation-based teaching of the FET had any effect on students’ achievements in the subject of basic electronic devices. Forty electronics students have participated in the study. Its findings indicate that in the short and long term alike, the achievements of students who studied the transistor through animation were significantly higher than those of their peers who studied it through a traditional method. Additionally, the effect size was very large.

Measures of Image Quality. Chapter 4

Energy Technology Data Exchange (ETDEWEB)

Maidment, A. D.A. [University of Pennsylvania, Philadelphia (United States)

2014-09-15

A medical image is a pictorial representation of a measurement of an object or function of the body. This information can be acquired in one to three spatial dimensions. It can be static or dynamic, meaning that it can also be measured as a function of time. Certain fundamental properties can be associated with all of these data. Firstly, no image can exactly represent the object or function; at best, one has a measurement with an associated error equal to the difference between the true object and the measured image. Secondly, no two images will be identical, even if acquired with the same imaging system of the same anatomic region; this variability is generally referred to as noise. There are many different ways to acquire medical image data; the various mechanisms of acquisition are described in detail in the subsequent chapters. However, regardless of the method of image formation, one must be able to judge the fidelity of the image in an attempt to answer the question “How accurately does the image portray the body or the bodily function?” This judgement falls under the rubric of ‘image quality’. In this chapter, methods of quantifying image quality are described.

Collective Intelligence. Chapter 17

Science.gov (United States)

Wolpert, David H.

2003-01-01

Many systems of self-interested agents have an associated performance criterion that rates the dynamic behavior of the overall system. This chapter presents an introduction to the science of such systems. Formally, collectives are defined as any system having the following two characteristics: First, the system must contain one or more agents each of which we view as trying to maximize an associated private utility; second, the system must have an associated world utility function that rates the possible behaviors of that overall system. In practice, collectives are often very large, distributed, and support little, if any, centralized communication and control, although those characteristics are not part of their formal definition. A naturally occurring example of a collective is a human economy. One can identify the agents and their private utilities as the human individuals in the economy and the associated personal rewards they are each trying to maximize. One could then identify the world utility as the time average of the gross domestic product. ("World utility" per se is not a construction internal to a human economy, but rather something defined from the outside.) To achieve high world utility it is necessary to avoid having the agents work at cross-purposes lest phenomena like liquidity traps or the Tragedy of the Commons (TOC) occur, in which agents' individually pursuing their private utilities lowers world utility. The obvious way to avoid such phenomena is by modifying the agents utility functions to be "aligned" with the world utility. This can be done via punitive legislation. A real-world example of an attempt to do this was the creation of antitrust regulations designed to prevent monopolistic practices.

Evaluation of use of reading comprehension strategies to improve reading comprehension of adult college students with acquired brain injury.

Science.gov (United States)

Griffiths, Gina G; Sohlberg, McKay Moore; Kirk, Cecilia; Fickas, Stephen; Biancarosa, Gina

2016-01-01

Adults with mild to moderate acquired brain injury (ABI) often pursue post-secondary or professional education after their injuries in order to enter or re-enter the job market. An increasing number of these adults report problems with reading-to-learn. The problem is particularly concerning given the growing population of adult survivors of ABI. Despite the rising need, empirical evaluation of reading comprehension interventions for adults with ABI is scarce. This study used a within-subject design to evaluate whether adult college students with ABI with no more than moderate cognitive impairments benefited from using reading comprehension strategies to improve comprehension of expository text. Integrating empirical support from the cognitive rehabilitation and special education literature, the researchers designed a multi-component reading comprehension strategy package. Participants read chapters from an introductory-level college anthropology textbook in two different conditions: strategy and no-strategy. The results indicated that reading comprehension strategy use was associated with recall of more correct information units in immediate and delayed free recall tasks; more efficient recall in the delayed free recall task; and increased accuracy recognising statements from a sentence verification task designed to reflect the local and global coherence of the text. The findings support further research into using reading comprehension strategies as an intervention approach for the adult ABI population. Future research needs include identifying how to match particular reading comprehension strategies to individuals, examining whether reading comprehension performance improves further through the incorporation of systematic training, and evaluating texts from a range of disciplines and genres.

Finally, we give recommendations for choosing the right instrument for a specific application, and how to ensure the accuracy of the measurement results..

Chapter 6: Temperature

Jones, Leslie A.; Muhlfeld, Clint C.; Hauer, F. Richard; F. Richard Hauer,; Lamberti, G.A.

2017-01-01

Stream temperature has direct and indirect effects on stream ecology and is critical in determining both abiotic and biotic system responses across a hierarchy of spatial and temporal scales. Temperature variation is primarily driven by solar radiation, while landscape topography, geology, and stream reach scale ecosystem processes contribute to local variability. Spatiotemporal heterogeneity in freshwater ecosystems influences habitat distributions, physiological functions, and phenology of all aquatic organisms. In this chapter we provide an overview of methods for monitoring stream temperature, characterization of thermal profiles, and modeling approaches to stream temperature prediction. Recent advances in temperature monitoring allow for more comprehensive studies of the underlying processes influencing annual variation of temperatures and how thermal variability may impact aquatic organisms at individual, population, and community based scales. Likewise, the development of spatially explicit predictive models provide a framework for simulating natural and anthropogenic effects on thermal regimes which is integral for sustainable management of freshwater systems.

Are Interpersonal Violence Rates Higher Among Young Women in College Compared With Those Never Attending College?

Science.gov (United States)

Coker, Ann L; Follingstad, Diane R; Bush, Heather M; Fisher, Bonnie S

2016-05-01

Estimates of sexual violence and partner violence rates among young women are generated primarily from college samples. Few studies have data to compare rates among similar-aged women attending college with those who never attended college. This study aims to estimate rates of partner violence by type (sexual, physical, and psychological) and severity (mild, moderate, severe), sexual harassment, and knowing or suspecting that someone put a drug in a drink (drugged drink) among a national sample of 959 young women aged 18 to 24 in an intimate relationship in the past 12 months who were either currently in college (college;n= 272) or never attended college (non-college;n= 687). After adjusting for demographic differences between these two groups, no significant differences were found in rates of sexual partner violence (28.4% non-college, 23.5% college), physical partner violence (27.9% non-college, 26.3% college), psychological partner violence (Mscore: 6.10 non-college, 5.59 college), sexual harassment (15.5% non-college, 14.1% college), or drugged drink (8.5% non-college, 7.8% college). Finding high rates of interpersonal violence among young women who are and are not currently attending college indicates the need to target all young adults with violence prevention interventions in educational, workplace, and other community-based settings. © The Author(s) 2015.

College Experience Scale (EExU

Directory of Open Access Journals (Sweden)

Angélica Juárez

2017-07-01

Full Text Available The experience of being a university student (University Experiences had been poorly studied so far. However, research in this field can provide valuable information about the quality of academic life, wellbeing or stress in this population. There is a lack of psychological tests that explore this theoretical construct. The aim of this study was to develop and validate a scale for measuring Univeristy Experiences, for that reason 314 college students were invited to participate for the validation. This students coursed different careers and reported 20 years old as average age. The University Experiences Scale (EExU has adequate psychometric properties. It has a structure of four factors: experience satisfaction, support perception, experience perception and life style adjustment. This factors explain 43.1% of the variance. The grouping of the factors of the College Experience Scale concurs with data reported in the literature about such concept, however this is the first questionnaire designed for measuring it. We anticipate that future studies will seek to verify the performance of the scale in different populations of students and analyze its psychometric properties and its possible association with other psychological variables that affect college students and their health.

Chapter 1: A Brief Introduction to Lignin Structure

Lignin is an alkyl-aromatic polymer found in the cell walls of terrestrial plants. Lignin provides structure and rigidity to plants, is a natural, highly effective barrier against microbial attack, and enables water and nutrient transport through plant tissues. Depending on the plant species, the constituents of lignin can vary considerably, leading to substantial diversity in lignin chemistry and structure. Despite nearly a century of research and development attempting to convert lignin into valuable products, lignin in most current and planned biorefinery contexts remains underutilized, most often being burned to generate heat and power. However, the drive towards effective lignin valorization processes has witnessed a significant resurgence in the past decade, catalyzed by advances in improved understanding of lignin chemistry, structure, and plasticity in parallel with new catalytic and biological approaches to valorize this important, prevalent biopolymer. As a preface to the subsequent chapters in this book, this chapter briefly highlights the known aspects of lignin structure.

Holt, Melissa K; Greif Green, Jennifer; Reid, Gerald; DiMeo, Amanda; Espelage, Dorothy L; Felix, Erika D; Furlong, Michael J; Poteat, V Paul; Sharkey, Jill D

2014-01-01

This study examined whether childhood bullying victimization was associated with psychosocial and academic functioning at college. The sample consisted of 413 first-year students from a large northeastern university. Students completed an online survey in February 2012 that included items assessing past bullying involvement, current psychosocial and academic functioning, and victimization experiences since arriving at college. Regression analyses indicated that reports of past bullying and other peer victimization were associated with lower mental health functioning and perceptions of physical and mental health, but were not associated with perceptions of social life at college, overall college experience, or academic performance. Childhood bullying victimization is associated with poorer mental and physical health among first-year college students. Colleges should consider assessing histories of bullying victimization, along with other past victimization exposures, in their service provision to students.

Boyraz, Güler; Horne, Sharon G; Owens, Archandria C; Armstrong, Aisha P

2016-01-01

The purpose of this study was to examine the relationship between depressive symptomatology and college outcomes among African American students, as well as to determine whether these relationships were moderated by gender and type of university. Participants included 569 African American first-year students attending two public universities in the Southeast United States: a historically Black college/university (HBCU) and a predominantly White institution (PWI). Using a longitudinal study design, data were collected at three time points. Results indicated that, after adjusting for the effects of the control variables (gender, type of institution, high school GPA, participation in on-campus activities, institutional and goal commitments), depressive symptomatology present in the first semester of college was associated with increased likelihood of dropping out of college before the end of the second year of college. The relationship between these two variables was mediated by first-year cumulative GPA. Results also indicated that the hypothesized relationships did not vary as a function of gender and the university type.

An Exploratory Study of Reading Comprehension in College Students After Acquired Brain Injury.

Science.gov (United States)

Sohlberg, McKay Moore; Griffiths, Gina G; Fickas, Stephen

2015-08-01

This exploratory study builds on the small body of existing research investigating reading comprehension deficits in college students with acquired brain injury (ABI). Twenty-four community college students with ABI completed a battery of questionnaires and standardized tests to characterize self-perceptions of academic reading ability, performance on a standardized reading comprehension measure, and a variety of cognitive functions of this population. Half of the participants in the sample reported traumatic brain injury (n = 12) and half reported nontraumatic ABI (n = 12). College students with both traumatic and nontraumatic ABI cite problems with reading comprehension and academic performance postinjury. Mean performance on a standardized reading measure, the Nelson-Denny Reading Test (Brown, Fischo, & Hanna, 1993), was low to below average and was significantly correlated with performance on the Speed and Capacity of Language Processing Test (Baddeley, Emslie, & Nimmo-Smith, 1992). Injury status of traumatic versus nontraumatic ABI did not differentiate results. Regression analysis showed that measures of verbal attention and suppression obtained from the California Verbal Language Test-II (Delis, Kramer, Kaplan, & Ober, 2000) predicted total scores on the Nelson-Denny Reading Test. College students with ABI are vulnerable to reading comprehension problems. Results align with other research suggesting that verbal attention and suppression problems may be contributing factors.

Closing the social-class achievement gap: a difference-education intervention improves first-generation students' academic performance and all students' college transition.

Science.gov (United States)

Stephens, Nicole M; Hamedani, MarYam G; Destin, Mesmin

2014-04-01

College students who do not have parents with 4-year degrees (first-generation students) earn lower grades and encounter more obstacles to success than do students who have at least one parent with a 4-year degree (continuing-generation students). In the study reported here, we tested a novel intervention designed to reduce this social-class achievement gap with a randomized controlled trial (N = 168). Using senior college students' real-life stories, we conducted a difference-education intervention with incoming students about how their diverse backgrounds can shape what they experience in college. Compared with a standard intervention that provided similar stories of college adjustment without highlighting students' different backgrounds, the difference-education intervention eliminated the social-class achievement gap by increasing first-generation students' tendency to seek out college resources (e.g., meeting with professors) and, in turn, improving their end-of-year grade point averages. The difference-education intervention also improved the college transition for all students on numerous psychosocial outcomes (e.g., mental health and engagement).

Fisher, Robert N.; Dodd, C. Kenneth

2016-01-01

This chapter enumerates the steps required in designing and planning field studies on the ecology and conservation of reptiles, as these involve a high level of uncertainty and risk. To this end, the chapter differentiates between goals (descriptions of what one intends to accomplish) and objectives (the measurable steps required to achieve the established goals). Thus, meeting a specific goal may require many objectives. It may not be possible to define some of them until certain experiments have been conducted; often evaluations of sampling protocols are needed to increase certainty in the biological results. And if sampling locations are fixed and sampling events are repeated over time, then both study-specific covariates and sampling-specific covariates should exist. Additionally, other critical design considerations for field study include obtaining permits, as well as researching ethics and biosecurity issues.

2009-01-01

Learning experiences for middle school girls are an effective means to steer young women toward secondary engineering curricula that they might not have otherwise considered. Sponsorship of such experiences by a collegiate student group is worthwhile, as it gives the group common purpose and places college students in a position to mentor these young women. This paper addresses learning experiences in different areas of bio-medical engineering offered to middle school girls in November 2008 via a day-long workshop entitled "Engineering The Body." The Kansas State University (KSU) Student Chapter of the IEEE Engineering in Medicine and Biology Society (EMBS) worked with the KSU Women in Engineering and Science Program (WESP) to design and sponsor these experiences, which addressed the areas of joint mechanics, electrocardiograms, membrane transport, computer mouse design, and audio filters for cochlear implants. Fifty five middle-school girls participated in this event, affirming the notion that biomedical engineering appeals to young women and that early education and recruitment efforts have the potential to expand the biomedical engineering talent pool.

John Paul College: The Professional Renewal Journey

Directory of Open Access Journals (Sweden)

Pauline Mundie

2014-09-01

Full Text Available John Paul College, a K-12 School in Queensland, Australia, recognises the centrality of classroom teachers to the ongoing improvement of student outcomes. The college has implemented a multi-tiered professional renewal and assessment process. These changes of emphasis are the result of significant research and subsequent/associated professional discussion and were supported during the EBA decision-making in 2012. The professional renewal process at John Paul College guides teachers through a cycle of goal setting (related to any aspect of teacher practice which aims to improve student learning and achievement; ongoing discussion between the teacher and a mentor which determines actions; directed classroom observations (3 per term and associated pre and post reflection/discussion; leading to application of changed practice toward achieving the criteria of the goals. The principles of the professional renewal program are to:  enhance development along accepted school-wide, team and department goals;  encourage professional pedagogical reflections and conversations with a colleague/mentor;  motivate improved performance and highlight the next steps in a teacher’s development. Through the introduction of professional renewal, attestation and exemplary teacher processes, the leadership and teachers of John Paul College have achieved an appropriate and innovative balance between self-directed, peer supported/directed and college-wide, strategic initiatives. Each member of the teaching team, from graduate to senior leaders are actively engaged in personalised programs of professional growth which is specifically aimed at improved learning and outcomes of the college’s students.

TOPCAT is a GUI interface on top of the STIL library. A command line interface to this library, STILTS, described in Chapter 21 provides scriptable access to many of the capabilities described here. The purpose of this tutorial is to provide an overview of TOPCAT to the novice user. The best place to look for and learn about TOPCAT is the web page maintained by Mark B. Taylor. There, TOPCAT documentation is provided in HTML, PDF, via screen shots, etc. In this chapter we take the user through a few examples that give the general idea of how TOPCAT works. The majority of the functionality of TOPCAT is not included in this short tutorial. Our goal in this tutorial is to lead the reader through an exercise that would result in a publication quality figure (e.g. for a journal article). Specifically, we will use TOPCAT to show how the color-magnitude relation of a galaxy cluster compares to that of all galaxies in the Sloan Digital Sky Survey (York et al. 2000). This diagnostic is used not only in cluster finding, but its linear fit can provide insight into the age and/or metallicity of the oldest galaxies in galaxy clusters (which are some of the oldest galaxies in the Universe). The data we need for this exercise are: 1) the entire spectroscopic galaxy catalog from the SDSS, with galaxy positions, galaxy

End-Of-Chapter (EOC) problems have been part of many physics education studies. Typically, only problems "localized" as relevant to a single chapter were used. This work examines how well this type of problem represents all EOC problems and whether EOC problems found in leading textbooks have changed over the past several decades. To…

This study described the process of developing and validating the College Chemistry Self-Efficacy Scale (CCSS) that can be used to assess college students’ beliefs in their ability to perform essential tasks in chemistry. In the first phase, data collected from 363 college students provided evidence for the validity and reliability of the new scale. Three dimensions emerged: self-efficacy for cognitive skills, self-efficacy for psychomotor skills, and self-efficacy for everyday applications. In the second phase, data collected from an independent sample of 353 college students confirmed the factorial structure of the 21-item CCSS. The Cronbach alpha coefficients ranged from 0.82 to 0.92. In addition, each dimension of the CCSS had moderate and significant correlations with student chemistry achievement and differentiated between major and non-major students. Followed by the additional validation studies, the CCSS will serve as a valuable tool for both instructors and researchers in science education to assess college students’ chemistry self-efficacy beliefs.
