Two studies examined the effectiveness of the Mac-a-Mug Pro, a computerized facial composite production system. In the first study, college freshmen prepared from memory composites of other students and faculty from their former high schools. Other students who had attended the same high schools could not recognize the composites of either students or faculty members when the composites of individuals known to them (n = 10) were mixed with composites of a large number (n = 40) of strangers. Neither preparer familiarity with the target, preparer-assessed composite quality, nor viewer familiarity predicted composite recognition. Study 2 indicated that naive witnesses who viewed the composites could not select the people depicted in the composites from photo lineups (1 target and 4 foils). The results raise questions about the efficacy of composite systems as tools to promote recognition of suspects in criminal contexts.

The performance of any engineering component depends on and is limited by the properties of the material from which it is fabricated. It is crucial for engineering students to understand these material properties, interpret them and select the right material for the right application. In this paper we present a new method to engage students with the material selection process. In a competition-based practical, first-year undergraduate students design, cost and cast composite chocolate samples to maximize a particular performance criterion. The same activity could be adapted for any level of education to introduce the subject of materials properties and their effects on the material chosen for specific applications.

The effects of school socio-economic composition on student achievement growth trajectories have been a hot topic of discussion among politicians around the world for many years. However, the bulk of research investigating school socio-economic composition effects has been limited in important ways. In an attempt to overcome the flaws in earlier research on school socio-economic composition effects, this study used data from a large sample, followed students throughout primary education, addressed selection bias problems, identified the grade(s) in which school socio-economic composition mattered the most, and studied the differential effects of school socio-economic composition by individual socio-economic status (SES). In a longitudinal design with seven occasions of data collection, the authors drew on a sample of N = 3,619 students (age at T1 about 5 years, age at T7 about 12 years) from 151 primary schools in Flanders (the northern part of Belgium). Students in low-, medium-, high-, and mixed-SES schools were matched using propensity scores. To compare students' achievement growth trajectories in the different school compositions, multilevel regression modelling with repeated measurements was applied. The results showed that students had more positive achievement growth in high-SES as compared to low-SES and mixed-SES schools. In two of the three comparisons, students in mixed-SES schools showed the lowest math development. The negative effects of mixed-SES schools on math achievement growth were the strongest for high-SES students. Our findings contribute to the ongoing discussion on the effects of school socio-economic composition on student achievement growth. © 2016 The British Psychological Society.

Direct composite fillings belong to widespread tooth restoration techniques in dental medicine. The procedure consists of successive steps, which include etching of the prepared tooth surface, bonding and placement of composite in incrementally built up layers. Durability and lifespan of the composite inlays strongly depend on the accurate completion of the individual steps to be also realized by students in dental medicine. Improper handling or nonconformity in the bonding procedure often lead to air enclosures (bubbles) as well as to significant gaps between the composite layers or at the margins of the restoration. Traditionally one analyzes the quality of the restoration cutting the tooth in an arbitrarily selected plane and inspecting this plane by conventional optical microscopy. Although the precision of this established method is satisfactory, it is restricted to the selected two-dimensional plane. Rather simple micro computed tomography (μCT) systems, such as SkyScan 1174™, allows for the non-destructive three-dimensional imaging of restored teeth ex vivo and virtually cutting the tomographic data in any desired direction, offering a powerful tool for inspection of the restored tooth with micrometer resolution before cutting and thus also to select a two-dimensional plane with potential defects. In order to study the influence of the individual steps on the resulted tooth restoration, direct composite fillings were placed in mod cavities of extracted teeth. After etching, an adhesive was applied in half of the specimens. From the tomographic datasets, it becomes clear that gaps occur more frequently when bonding is omitted. The visualization of air enclosures offers to determine the probability to find a micrometer-sized defect using an arbitrarily selected cutting plane for inspection.

Background Prior to 1999 students entering our MBBS course were selected on academic performance alone. We have now evaluated the impact on the demographics of subsequent cohorts of our standard entry students (those entering directly from high school) of the addition to the selection process of an aptitude test (UMAT), a highly structured interview and a rural incentive program. Methods Students entering from 1985 to 1998, selected on academic performance alone (N = 1402), were compared to those from 1999 to 2011, selected on the basis of a combination of academic performance, interview score, and UMAT score together with the progressive introduction of a rural special entry pathway (N = 1437). Results Males decreased from 57% to 45% of the cohort, students of NE or SE Asian origin decreased from 30% to 13%, students born in Oceania increased from 52% to 69%, students of rural origin from 5% to 21% and those from independent high schools from 56% to 66%. The proportion of students from high schools with relative socio-educational disadvantage remained unchanged at approximately 10%. The changes reflect in part increasing numbers of female and independent high school applicants and the increasing rural quota. However, they were also associated with higher interview scores in females vs males and lower interview scores in those of NE and SE Asian origin compared to those born in Oceania or the UK. Total UMAT scores were unrelated to gender or region of origin. Conclusions The revised selection processes had no impact on student representation from schools with relative socio-educational disadvantage. However, the introduction of special entry quotas for students of rural origin and a structured interview, but not an aptitude test, were associated with a change in gender balance and ethnicity of students in an Australian undergraduate MBBS course.

There is seemingly some inherent component in selected musical compositions that elicits specific emotional perceptions, feelings, and physical conduct. The purpose of the study was to determine if the emotional perceptions of those listening to classical music are inherent in the composition or acquired by the listeners. Fifteen kindergarten students, aged 5 years, from three different sociocultural groups, were evaluated. They were exposed to portions of five purposefully selected classical compositions and asked to describe their emotions when listening to these musical pieces. All were instrumental compositions without human voices or spoken language. In addition, they were played to an audience of an age at which they were capable of describing their perceptions and supposedly had no significant previous experience of classical music. Regardless of their sociocultural background, the children in the three groups consistently identified similar emotions (e.g. fear, happiness, sadness), feelings (e.g. love), and mental images (e.g. giants or dangerous animals walking) when listening to specific compositions. In addition, the musical compositions generated physical conducts that were reflected by the children's corporal expressions. Although the sensations were similar, the way of expressing them differed according to their background.

The use and validity of the Graduate Record Examination General Test (GRE) to predict the success of graduate school applicants is heavily debated, especially for its possible impact on the selection of underrepresented minorities into science, technology, engineering, and math fields. To better identify candidates who would succeed in our program with less reliance on the GRE and grade point average (GPA), we developed and tested a composite score (CS) that incorporates additional measurable predictors of success to evaluate incoming applicants. Uniform numerical values were assigned to GPA, GRE, research experience, advanced course work or degrees, presentations, and publications. We compared the CS of our students with their achievement of program goals and graduate school outcomes. The average CS was significantly higher in those students completing the graduate program versus dropouts (p < 0.002) and correlated with success in competing for fellowships and a shorter time to thesis defense. In contrast, these outcomes were not predicted by GPA, science GPA, or GRE. Recent implementation of an impromptu writing assessment during the interview suggests the CS can be improved further. We conclude that the CS provides a broader quantitative measure that better predicts success of students in our program and allows improved evaluation and selection of the most promising candidates.

Foreign-born Peers and Academic Performance.
Conger, Dylan
2015-04-01
The academic performance of foreign-born youth in the United States is well studied, yet little is known about whether and how foreign-born students influence their classmates. In this article, I develop a set of expectations regarding the potential consequences of immigrant integration across schools, with a distinction between the effects of sharing schools with immigrants who are designated as English language learners (ELL) and those who are not. I then use administrative data on multiple cohorts of Florida public high school students to estimate the effect of immigrant shares on immigrant and native-born students' academic performance. The identification strategy pays careful attention to the selection problem by estimating the effect of foreign-born peers from deviations in the share foreign-born across cohorts of students attending the same school in different years. The assumption underlying this approach is that students choose schools based on the composition of the entire school, not on the composition of each entering cohort. The results of the analysis, which hold under several robustness checks, indicate that foreign-born peers (both those who are ELL and those who are non-ELL) have no effect on their high school classmates' academic performance.

Abnormal eating behavior, unhealthy weight control methods, and eating disordered symptoms have risen among college students. The aim of this study was to examine disordered eating attitudes and their relationship with anthropometric and body composition indices in physical education students in Tabriz, the capital of East Azerbaijan province, Iran. This cross-sectional study was conducted on 210 physical education students, 105 males and 105 females aged 18 to 25, who were selected by systematic random sampling from physical education faculty of Tabriz University in Tabriz, Iran, in 2013. Eating attitude test (EAT-26) was used for the assessment of disordered eating attitudes. In addition, anthropometric and body composition indices were assessed. About 10% of the studied subject had disturbed eating attitudes; significantly more males (15.4%) reported an EAT-26 ≥ 20 (disordered eating attitudes) than females (4.8%) (P < 0.05). In males, the EAT-26 score was positively correlated with weist perimeter (WP) (r = 0.21, P < 0.05) and the waist-to-hip ratio (r = 0.26, P < 0.01). In females, the EAT-26 score was positively correlated with weight (r = 0.19, P < 0.05) and the WP (r = 0.28, P < 0.01). In females, weight (P < 0.05), body mass index (BMI) (P < 0.05), WP (P < 0.01), and waist-to-hip ratio (P < 0.05) were significantly different between disordered eating attitude and healthy subjects, while in males there was no significant difference between the two groups regarding the anthropometric and body composition indices. Abnormal eating attitude was notable among physical education students in Tabriz, Iran. It seems that some anthropometric indices such as BMI and central obesity indices were related to the increase of disordered eating attitude.

The study examines science-related course choices of high-school students in the culturally diverse schools of the province of British Columbia, Canada. The analysis employs K-12 provincial data and includes over 44,000 students born in 1990 who graduated from high school by 2009. The research sample reflects the presence of about 27% of students for whom English is not a first language. We construct an empirical model that examines ethno-linguistic and gender differences in Grade 12 course choices while accounting for personal and situational differences among students. The study employs a course selection typology that emphasizes readiness for science, technology, engineering and math fields of study. Findings indicate that math- and science-related course selection patterns are strongly associated with ethnicity, qualified not only by gender and prior math and science achievement but also by the individual's grade level at entry to the system and enrollment in English as a Second Language program. Students who are more likely to engage in math and science courses belong to Asian ethno-linguistic groups and entered the provincial school system during the senior high-school years. We suggest that ethnic diversity and broader academic exposure may play a crucial role in changing the gender composition of science classrooms, university fields of study and science-related occupations.

School cafeterias can play an important role in providing healthy meals. Although schools participating in the National School Lunch Program are required to meet minimum program standards, advocates recommend that innovations be sought to enhance menu dietary quality. This study evaluated the Chef Initiative, a 2-year pilot study in two Boston middle schools, designed to increase the availability and consumption of healthier school foods. Between 2007 and 2009, a professional chef trained cafeteria staff to prepare healthier school lunches (ie, more whole grains, fresh/frozen fruits and vegetables, and less sugar, salt, saturated fats, and trans fats). Meal nutrient compositions were monitored from 2007 to 2009, and a plate waste study conducted in the spring of 2009 compared food selection and consumption patterns among students at Chef Initiative schools, with students receiving standard school lunches at two matched control schools. Paired t tests and descriptive statistics were used to examine differences in menus and mixed-model analysis of variance was used to analyze differences in students' food selection and consumption between Chef Initiative and control schools. Overall, the Chef Initiative schools provided healthier lunches and the percent of foods consumed at Chef Initiative and control schools were similar (61.6% vs 57.3%; P=0.63). Of the areas targeted, there was greater whole-grain selection and vegetable consumption; 51% more students selected whole grains (P=0.02) and students consumed 0.36 more vegetable servings/day (P=0.01) at Chef Initiative schools. The potential of chefs collaborating with cafeteria staff to improve the availability, selection, and consumption of healthier meals is promising. Copyright © 2012 Academy of Nutrition and Dietetics.

Energy drinks are among the most popular functional products. They contain bioactive substances which may produce beneficial effects on the body, but excessive consumption of energy drinks or use them in accordance with their intended use may be dangerous to health. The aim of the study was to assess determinants and circumstances of energy drinks consuming in selected group of students, their opinion and knowledge on energy drinks. The study was conducted in March 2011 in Warsaw and included 92 students from Warsaw University of Life Sciences (WULS) and from University of Physical Education (UPE). The data was collected using diagnostic survey. Energy drinks consumed 67% of the respondents. The most common reason for drinking energy drinks was to stay awake (45.2%). They most often drank them during the examination session (21.0%) and afterwards they experienced stimulation (72.9%), but also palpitations (32.2%) and insomnia (25.8%). Students who consumed energy drinks confirmed that they are effective (88.7%) and tasty (41.9%), but dangerous for health (43.5%). Majority of all users of energy drinks (80.7%) mixed them with alcohol. Every fourth respondent did not read the composition of the consumed beverages. Energy drinks have been a popular food product among students. After energy drinks consumption students often felt agitated but also experienced negative symptoms. Young people have to pay attention to the composition of energy drinks, what proves their consciousness.

Early adulthood is related to changes in lifestyle that negatively affect body weight and health. The aim of the study was to determine the effect of exercise changes on the development of weight and body composition in college students.Sixty-one randomly selected dental (ZMS) and 53 sport students (SLS) were accompanied over 5 years. Body mass, fat and lean body mass (LBM) were determined via DXA-technique. Exercise and physical activity were assessed by questionnaires and interviews.All exercise indices significantly increased in the SLS and significantly decreased in the ZMS. Physical activity slightly increased in both groups. Both cohorts comparably gained body mass, however, the increase in the SLS group can be attributed to LBM-changes with minor changes of fat-mass (2.4 % ± 3.3 % vs. 0.1 ± 1.0 %) whereas ZMS gained fat and LBM in a proportion of 2:1.Maintenance/increase of exercise compensate the negative effects of lifestyle changes on body composition during young adulthood.

Ecological and personal predictors of science achievement in an urban center
NASA Astrophysics Data System (ADS)
Guidubaldi, John Michael
This study sought to examine selected personal and environmental factors that predict urban students' achievement test scores on the science subject area of the Ohio standardized test. Variables examined were in the general categories of teacher/classroom, student, and parent/home. It assumed that these clusters might add independent variance to a best predictor model, and that discovering relative strength of different predictors might lead to better selection of intervention strategies to improve student performance. This study was conducted in an urban school district and was comprised of teachers and students enrolled in ninth grade science in three of this district's high schools. Consenting teachers (9), students (196), and parents (196) received written surveys with questions designed to examine the predictive power of each variable cluster. Regression analyses were used to determine which factors best correlate with student scores and classroom science grades. Selected factors were then compiled into a best predictive model, predicting success on standardized science tests. Students t tests of gender and racial subgroups confirmed that there were racial differences in OPT scores, and both gender and racial differences in science grades. Additional examinations were therefore conducted for all 12 variables to determine whether gender and race had an impact on the strength of individual variable predictions and on the final best predictor model. Of the 15 original OPT and cluster variable hypotheses, eight showed significant positive relationships that occurred in the expected direction. However, when more broadly based end-of-the-year science class grade was used as a criterion, 13 of the 15 hypotheses showed significant relationships in the expected direction. With both criteria, significant gender and racial differences were observed in the strength of individual predictors and in the composition of best predictor models.

This study examined interactions between middle school science students' perceptions of teacher-student interactions and their motivation for learning science. Specifically, in order to better understand factors affecting middle school students' motivation for science, this study investigated the interactions between middle school students' perceptions of teacher interpersonal behavior in their science classroom and their efficacy, task value, mastery orientations, and goal orientation for learning science. This mixed methods study followed a sequential explanatory model (Cresswell & Plano-Clark, 2007). Quantitative and qualitative data were collected in two phases, with quantitative data in the first phase informing the selection of participants for the qualitative phase that followed. The qualitative phase also helped to clarify and explain results from the quantitative phase. Data mixing occurred between Phase One and Phase Two (participant selection) and at the interpretation level (explanatory) after quantitative and qualitative data were analyzed separately. Results from Phase One indicated that students' perceptions of teacher interpersonal behaviors were predictive of their efficacy for learning science, task value for learning science, mastery orientation, and performance orientation. These results were used to create motivation/perception composites, which were used in order to select students for the qualitative interviews. A total of 24 students with high motivation/high perceptions, low motivation/low perceptions, high motivation/low perceptions, and low motivation/high perceptions were selected in order to represent students whose profiles either supported or refuted the quantitative results. Results from Phase Two revealed themes relating to students' construction of their perceptions of teacher interpersonal behavior and dimensions of their efficacy and task value for science. Students who reported high motivation and high perceptions of teacher-student interactions during the quantitative phase described the most instances of teacher cooperative behaviors, such as teacher helpfulness and understanding. Conversely, students reporting low motivation and low perceptions of teacher-student interactions described the most instances of teacher oppositional behavior, such as harsh and impatient behaviors. An in-depth description of categories and subcategories is also provided. This study concludes with an interpretive analysis of quantitative and qualitative results considered both separately and together. Implications for middle grades science education are discussed, including recommendations for behavior management, scaffolding students' transition to middle school, making explicit connections to science careers, and providing opportunities for small successes within the science classroom. Implications for science teacher education, limitations of the study, and future research directions are also discussed.

In this paper we present a study on the difficulties secondary school students experience in interpreting textbook images of elementary astronomical phenomena, namely, the changing of the seasons, Sun and lunar eclipses and Moon phases. Six images from a commonly used textbook in Italian secondary schools were selected. Interviews of 45 min about the astronomical concepts related to the images were carried out with eighteen students attending the last year of secondary school (aged 17-18). Students’ responses were analyzed through a semiotic framework based on the different types of visual representation structures. We found that the wide range of difficulties shown by students come from naïve or alternative ideas due to incorrect or inadequate geometric models of the addressed phenomena. As a primary implication of this study, we suggest that teachers should pay attention to specific iconic features of the discussed images, e.g., the compositional structure and the presence of real/symbolic elements.

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.

In order to solve the unconcern to usefulness of learning science among high school students in Japan, we developed a simple fabricated taste sensor with sensitivity and selectivity to each taste quality, which can be applied in science class. A commercialized Teflon membrane was used as the polymer membrane holding lipids. In addition, a non-adhesive method is considered to combine the membrane and the sensor electrode using a plastic cap which is easily accessible. The taste sensor for education fabricated in this way showed a good selectivity and sensitivity. By adjusting the composition of trioctylmethylammonium chloride (TOMA) and phosphoric acid di(2-ethylhexyl) ester (PAEE) included in lipid solution, we improved the selectivity of this simple taste sensor to saltiness and sourness. To verify this taste sensor as a useful science teaching material for science class, we applied this taste sensor into a science class for university students. By comparing the results between the sensory test and the sensor response, humans taste showed the same tendency just as the sensor response, which proved the sensor as a useful teaching material for science class.

Texts and software that we are currently using for teaching multivariate analysis to non-statisticians lack in the delivery of confirmatory factor analysis (CFA). The purpose of this paper is to provide educators with a complement to these resources that includes CFA and its computation. We focus on how to use CFA to estimate a “composite reliability” of a psychometric instrument. This paper provides guidance for introducing, via a case-study, the non-statistician to CFA. As a complement to our instruction about the more traditional SPSS, we successfully piloted the software R for estimating CFA on nine non-statisticians. This approach can be used with healthcare graduate students taking a multivariate course, as well as modified for community stakeholders of our Center for American Indian Community Health (e.g. community advisory boards, summer interns, & research team members). The placement of CFA at the end of the class is strategic and gives us an opportunity to do some innovative teaching: (1) build ideas for understanding the case study using previous course work (such as ANOVA); (2) incorporate multi-dimensional scaling (that students already learned) into the selection of a factor structure (new concept); (3) use interactive data from the students (active learning); (4) review matrix algebra and its importance to psychometric evaluation; (5) show students how to do the calculation on their own; and (6) give students access to an actual recent research project.

Pasero, Spencer Lee; /Northern Illinois U.
Hundreds of high schools around the United States have inverted the traditional core sequence of high school science courses, putting physics first, followed by chemistry, and then biology. A quarter-century of theory, opinion, and anecdote are available, but the literature lacks empirical evidence of the effects of the program. The current study was designed to investigate the effects of the program on science achievement gain, growth in attitude toward science, and growth in understanding of the nature of scientific knowledge. One hundred eighty-five honor students participated in this quasi-experiment, self-selecting into either the traditional or inverted sequence. Students took themore » Explore test as freshmen, and the Plan test as sophomores. Gain scores were calculated for the composite scores and for the science and mathematics subscale scores. A two-factor analysis of variance (ANOVA) on course sequence and cohort showed significantly greater composite score gains by students taking the inverted sequence. Participants were administered surveys measuring attitude toward science and understanding of the nature of scientific knowledge twice per year. A multilevel growth model, compared across program groups, did not show any significant effect of the inverted sequence on either attitude or understanding of the nature of scientific knowledge. The sole significant parameter showed a decline in student attitude independent of course sequence toward science over the first two years of high school. The results of this study support the theory that moving physics to the front of the science sequence can improve achievement. The importance of the composite gain score on tests vertically aligned with the high-stakes ACT is discussed, and several ideas for extensions of the current study are offered.« less
How college science students engage in note-taking strategies

A composite theory of college science student note-taking strategies was derived from a periodic series of five interviews with 23 students and with other variables, including original and final versions of notes analyzed during a semester-long genetics course. This evolving composite theory was later compared with Van Meter, Yokoi, and Pressley's (Journal of Educational Psychology, 86, 323-338, 1994) corresponding composite college students' theory of note-taking. Students' notes in this long-term study were also compared with a standard of adequate note-taking established by experts. Analyses detected many similarities between the two composite theories. Analyses also provided evidence of inadequate note-taking strategies, inconsistencies between what students claimed and evidently did with their notes, and weak self-regulating learning strategies. Recommendations included prompting students during class on how to take notes.

Medical schools worldwide are faced with the challenge of selecting from among many qualified applicants. One factor that might help admissions committees identify future exceptional medical students is scores on standardized entrance exams. The purpose of this study was to determine the association between scores on the most commonly used standardized medical school entrance exam in the USA, the Medical College Admission Test (MCAT), and election to the US medical honors society, Alpha Omega Alpha (AOA). MCAT scores and AOA membership data were analyzed for all the students pursuing Doctor of Medicine degrees at the University of Minnesota Medical School and who graduated between 2012-2016 (n=1,309). An independent-samples t -test found a significant difference (t=6.132, p <0.001) in MCAT scores between those who were elected to AOA (n=179) and those who were not (n=1,130). On average, students who were elected to AOA had composite MCAT scores of 1.65 points higher than those who were not. Percentages of students elected to AOA gradually but inconsistently increased with MCAT score. No student who scored <27 on the MCAT was elected to AOA. Among students with MCAT scores at the 99th percentile or above (scores of ≥38), 13 of 48 (27.1%) were elected to AOA. Election to AOA during medical school was significantly associated with higher MCAT scores. Admissions committees should carefully consider the role of standardized entrance exam scores, in the context of a holistic review, when selecting for exceptional medical students.

To evaluate the effects of egg and milk supplementation on growth and development and body composition among children in poor rural area in Tianyang County of Guangxi province. Total four schools were randomly selected from four towns in Tianyang County of Guangxi province as intervention group in April, 2013. The intervention measures included that these students were given salty egg (net weight: 50 g) and ultra-high-temperature-sterilization school milk (net weight: 200 g) every school day and these schools were equipped with standard kitchens. Another four schools of familiar socio-economic level, teaching quality and size from the same town were randomly chosen as control group and none of the intervention measures were implemented. About 25 students were randomly selected and stratified by grades from grade one to grade five. The height, weight, and body composition of all students were measured in April, 2013 and one year after the intervention. A total of 978 students were measured at baseline from age 6 to 13, 552 students as intervention group and 426 as control group. t-test was used to compare the differences between groups and multivariate unconditional logistic regression was used to analyze the factors of malnutrition. After one year intervention, 892 students were measured randomly, with 515 students in intervention group and 377 in control one. The average weight of boys in intervention group increased (3.6 ± 1.7) kg compared with baseline. It was significantly higher than that of control group ((2.9 ± 1.5) kg) (t = 4.40, P < 0.001). The boy's lean body mass of intervention group increased (2.6 ± 1.4) kg, higher than the control group ((2.0 ± 1.2) kg) (t = 3.95, P < 0.001). The decrease of malnutrition rate of intervention schools (11.8%) was significantly higher than that of the control schools (4.7%, χ² = 16.90, P < 0.001), and the odds ratio was 0.37 (95% CI: 0.23-0.59). The risk difference of overweight and obesity was not statistically significant between the two groups (OR = 1.68, 95% CI: 0.57-4.94). After supplementing milk and egg, the nutritional status of the poor rural pupils was improved.

Doing peer review has been effectively implemented to help students develop critical reading and writing skills; however, its application in Human Physiology programs is limited. The purpose of the present study was to determine the impact of peer review on Human Physiology majors' perceptions of their scientific literacy and writing skills. Students enrolled in the Scientific Writing course completed multiple writing assignments, including three revisions after receiving peer and instructor feedback. Students self-assessed their knowledge, skills, and attitudes related to science and writing in pre- and postcourse surveys (n = 26 with complete data). Seven survey items related to scientific literacy and writing skills impacted by peer review were selected for analysis. Scores on these survey items were summed to form a composite self-rating score. Responses to two questions regarding the most useful learning activities were submitted to frequency analysis. Mean postcourse scores for individual survey items and composite self-rating scores were significantly higher than precourse means (P < 0.05). Peer review was the most frequently noted among 21 learning activities for increasing scientific literacy and in the top 5 for improving writing skills. In conclusion, peer review is an effective teaching/learning approach for improving undergraduate Human Physiology majors' knowledge, skills, and attitudes regarding science and scientific writing.

Motivation of medical students: selection by motivation or motivation by selection.
Wouters, Anouk; Croiset, Gerda; Galindo-Garre, Francisca; Kusurkar, Rashmi A
2016-01-29
Medical schools try to implement selection procedures that will allow them to select the most motivated students for their programs. Though there is a general feeling that selection stimulates student motivation, conclusive evidence for this is lacking. The current study aims to use the perspective of Self-determination Theory (SDT) of motivation as a lens to examine how medical students' motivation differs in relation to different selection procedures. The hypotheses were that 1) selected students report higher strength and autonomous motivation than non-selected students, and 2) recently selected students report higher strength and autonomous motivation than non-selected students and students who were selected longer ago. First- (Y1) and fourth-year (Y4) medical students in the six-year regular programme and first-year students in the four-year graduate entry programme (GE) completed questionnaires measuring motivation strength and type (autonomous-AM, controlled-CM). Scores were compared between students admitted based on selection, lottery or top pre-university GPA (top GPA) using ANCOVAs. Selected students' answers on open-ended questions were analysed using inductive thematic analysis to identify reasons for changes in motivation. The response rate was 61.4 % (n = 357). Selected students (Y1, Y4 and GE) reported a significantly higher strength of motivation than non-selected students (Y1 and Y4 lottery and top GPA) (p < 0.01). Recently selected students (Y1 and GE) reported significantly higher strength (p < 0.01) and higher AM (p < 0.01) and CM (p < 0.05) than non-selected students (lottery and top GPA) and Y4 students who were selected three years ago. Students described that being selected enhanced their motivation as they felt autonomous, competent and that they belonged to a special group. These reported reasons are in alignment with the basic psychological needs described by Self-Determination Theory as important in enhancing autonomous motivation. A comprehensive selection procedure, compared to less demanding admission procedures, does not seem to yield a student population which stands out in terms of autonomous motivation. The current findings indicate that selection might temporarily enhance students' motivation. The mechanism through which this occurs seems to be through feelings of autonomy, competence and relatedness inspired by selection.

This report conducts a material selection of different types of steel for UBC Steel Bridge Team. I am a third-year material engineering student, so the result from this material selection can only be taken into consideration but not fully adopted. As part of my academic journey, it is possible for technical mistakes in this material selection process. The mechanic properties are the most effective category of properties, making it necessary to be justified from the steel bridge design and chosen in accordance with the objective of the team. An introduction for currently-used steel properties and the expected steel properties is provided. The examination focus on how different alloy compositions of steel changes its properties. The properties of the steel are examined in three main aspects: hardness, strength, and toughness. The results suggest that more nickel, manganese, and chromium in the steel provide better steel for the team to use. Further research is needed if a more precise material selection is required.

Posttraumatic stress disorder (PTSD) is the most common consequence of traumatic experiences. The North Central Nigeria to which Plateau State belongs has witnessed many ethno-religious crises. While previous studies suggested a high prevalence of PTSD among students, to the best of our knowledge, no such study has been reported in Nigeria. The study aimed to determine the prevalence and correlates of PTSD among medical students in a university. Cross-sectional systematic random sampling was used to select 200 medical students. A two staged interview with questionnaire on sociodemographic variables, PTSD Checklist-Civilian Version, Impact of Event Scale, and Composite International Diagnostic Interview was carried out. SPSS Inc. Released 2007. SPSS for Windows, version 16.0. Chicago, SPSS Inc. was used for statistical analysis. Prevalence of PTSD among the students was 23.5%. Previous childhood trauma and personal experiences during the crisis were significantly associated with having PTSD.

Australian accreditation standards for occupational therapy courses require consumer participation in the design, delivery and evaluation of programs. This study investigated whether a mental health consumer - as one of two assessors for an oral assessment in a mental health unit - impacted engagement, anxiety states and academic performance of undergraduate occupational therapy students. Students (n = 131 eligible) self-selected into two groups but were blinded to the group differences (assessor panel composition) until shortly prior to the oral assessment. Control group assessors were two occupational therapy educators, while consumer group assessors included an occupational therapy educator and a mental health consumer. Pre- and post-assessment data were successfully matched for 79 students (overall response rate = 73.1%). No evidence was found of significant differences between the two groups for engagement, anxiety or academic performance (all P values >0.05). Including mental health consumers as assessors did not negatively impact student engagement and academic performance, nor increase student anxiety beyond that typically observed in oral assessment tasks. The findings provide support for expanding the role of mental health consumers in the education and assessment of occupational therapy students. Development of methods to determine the efficacy of consumer involvement remains an area for future research. © 2018 Occupational Therapy Australia.

Introduction A consistent body of literature highlights the importance of a broader approach to select medical school candidates both assessing cognitive capacity and individual characteristics. However, selection in a great number of medical schools worldwide is still based on knowledge exams, a procedure that might neglect students with needed personal characteristics for future medical practice. We investigated whether the personal profile of students selected through a knowledge-based exam differed from those not selected. Methods Students applying for medical school (N=311) completed questionnaires assessing motivations for becoming a doctor, learning approaches, personality traits, empathy, and coping styles. Selection was based on the results of MCQ tests. Principal component analysis was used to draw a profile of the students. Differences between selected and non-selected students were examined by Multivariate ANOVAs, and their impact on selection by logistic regression analysis. Results Students demonstrating a profile of diligence with higher conscientiousness, deep learning approach, and task-focused coping were more frequently selected (p=0.01). Other personal characteristics such as motivation, sociability, and empathy did not significantly differ, comparing selected and non-selected students. Conclusion Selection through a knowledge-based exam privileged diligent students. It did neither advantage nor preclude candidates with a more humane profile. PMID:27079886

A method of preparing advanced membrane electrode assemblies (MEA) for use in fuel cells. A base polymer is selected for a base membrane. An electrode composition is selected to optimize properties exhibited by the membrane electrode assembly based on the selection of the base polymer. A property-tuning coating layer composition is selected based on compatibility with the base polymer and the electrode composition. A solvent is selected based on the interaction of the solvent with the base polymer and the property-tuning coating layer composition. The MEA is assembled by preparing the base membrane and then applying the property-tuning coating layer to form a composite membrane. Finally, a catalyst is applied to the composite membrane.

Students' perceptions of engineering have been documented through studies involving interviews, surveys, and word associations that take a direct approach to asking students about various aspects of their understanding of engineering. Research on perceptions of engineering rarely focuses on how students would portray engineering to others. First-year engineering student teams proposed a museum exhibit, targeted to middle school students, to explore the question "What is engineering?" The proposals took the form of a poster. The overarching research question focuses on how these students would portray engineering to middle school students as seen through their museum exhibit proposals. A preliminary analysis was done on 357 posters to determine the overall engineering themes for the proposed museum exhibits. Forty of these posters were selected and, using open coding, more thoroughly analyzed to learn what artifacts/objects, concepts, and skills student teams associate with engineering. These posters were also analyzed to determine if there were any differences by gender composition of the student teams. Building, designing, and teamwork are skills the first-year engineering students link to engineering. Regarding artifacts, students mentioned those related to transportation and structures most often. All-male teams were more likely to focus on the idea of space and to mention teamwork and designing as engineering skills; equal-gender teams were more likely to focus on the multidisciplinary aspect of engineering. This analysis of student teams' proposals provides baseline data, positioning instructors to develop and assess instructional interventions that stretch students' self-exploration of engineering.
Tree cover and species composition effects on academic performance of primary school students.

Human exposure to green space and vegetation is widely recognized to result in physical and mental health benefits; however, to date, the specific effects of tree cover, diversity, and species composition on student academic performance have not been investigated. We compiled standardized performance scores in Grades 3 and 6 for the collective student body in 387 schools across the Toronto District School Board (TDSB), and examined variation in relation to tree cover, tree diversity, and tree species composition based on comprehensive inventories of trees on school properties combined with aerial-photo-based assessments of tree cover. Analyses accounted for variation due to socioeconomic factors using the learning opportunity index (LOI), a regional composite index of external challenges to learning that incorporates income and other factors, such as students with English as a second language. As expected, LOI had the greatest influence on student academic performance; however, the proportion of tree cover, as distinct from other types of "green space" such as grass, was found to be a significant positive predictor of student performance, accounting for 13% of the variance explained in a statistical model predicting mean student performance assessments. The effects of tree cover and species composition were most pronounced in schools that showed the highest level of external challenges, suggesting the importance of urban forestry investments in these schools.

The university students need to consolidate good dietary habits based on an adequate selection of food, which is a factor of fundamental importance to maintain good health and prevent disease. to evaluate the food intake and diet profile of university students from Tucumán and its variation over time. Analyse if they accomplish current dietary recommendations. Data collection was carried out during the years 1998-1999 (G1) and 2012-2013 (G2); was performed by a self-survey and food frequency questionnaire of food consumption. It was applied to 329 university students selected randomly. The dietary pattern was described by frequency of usual consumption of principal food groups. Students were 25.2% male and 74.8% female, mean age 23 ± 3 years. In general, in both groups most of the students had a normal BMI, but had a high percentage of men with overweight (18.2%) and obesity (12.1%) and women with underweight (11.6%). According to the groups and sex analysis some significant statistically differences in macronutrient composition of the diet were observed: the G1 was higher carbohydrate intake than proteins and lipids; also differences in the intake of some micronutrients were found, with a higher intake of iron and less intake of vitamins B1, B2, niacin and C in G2. The diet was monotonous for both groups and with differences in the profile of nutrients. The most notable was the gradual increase consumption of sugary products, processed foods, snacks and decrease consumption of dairy, fish, fruits and vegetables in G2. In both groups, adequacy of dietary intake of the university students did not cover the recommendations of iron, calcium and vitamin A. Given the food profile observed in the student population, is warned the need to promote changes to prevent the development of obesity and cardiovascular disease in adulthood; it should be convenient to carrying out food and nutrition education.

To study the prevalence and risk factors of neurotic disorders (NDs) among Chinese university students. Stratified random sampling was used to select students who were interviewed using the World Health Organization Composite International Diagnostic Interview Version 3.0 to diagnose psychiatric disorder and collected socio-demographic, and family structure and environment data. The response rate was 90 % (N = 1,843). The International Statistical Classification of Diseases and Related Health Problems 10th Revision (ICD-10) criteria were used to diagnose NDs. We used logistical regression to evaluate the links between NDs and selected correlates. The prevalence of NDs was 25.6 % (lifetime), 15.7 % (12-month), and 6.8 % (30-day) among the university students with no significant gender differences in these rates. No family structure characteristics were related to 12-month prevalence of NDs (P > 0.05). In contrast, family environment factors including a history of family disputes (OR 1.562, CI 1.108-2.203), parental mental health problems (OR 1.800, CI 1.379-2.349), and absence of care in childhood (OR 1.916, 95 % CI 1.331-2.759) were associated with higher prevalence rates of NDs. Our findings show a high prevalence of NDs in this sample of Chinese undergraduates. Social environment factors, in the student's family of orientation, were significantly associated with the prevalence of NDs. These findings support the importance of negative family experiences during childhood and adolescence and increasing vulnerability to NDs.

Very few studies have reported on the effect of admission tests on medical school dropout. The main aim of this study was to evaluate the predictive validity of non-grade-based admission testing versus grade-based admission relative to subsequent dropout. This prospective cohort study followed six cohorts of medical students admitted to the medical school at the University of Southern Denmark during 2002-2007 (n=1544). Half of the students were admitted based on their prior achievement of highest grades (Strategy 1) and the other half took a composite non-grade-based admission test (Strategy 2). Educational as well as social predictor variables (doctor-parent, origin, parenthood, parents living together, parent on benefit, university-educated parents) were also examined. The outcome of interest was students' dropout status at 2 years after admission. Multivariate logistic regression analysis was used to model dropout. Strategy 2 (admission test) students had a lower relative risk for dropping out of medical school within 2 years of admission (odds ratio 0.56, 95% confidence interval 0.39-0.80). Only the admission strategy, the type of qualifying examination and the priority given to the programme on the national application forms contributed significantly to the dropout model. Social variables did not predict dropout and neither did Strategy 2 admission test scores. Selection by admission testing appeared to have an independent, protective effect on dropout in this setting. © Blackwell Publishing Ltd 2011.

This study sought to identify a variable or variables predictive of attrition among baccalaureate nursing students. The study was quantitative in design and multivariate correlational statistics and discriminant statistical analysis were used to identify a model for prediction of attrition. The analysis then weighted variables according to their predictive value to determine the most parsimonious model with the greatest predictive value. Three public university nursing education programs in Mississippi offering a Bachelors Degree in Nursing were selected for the study. The population consisted of students accepted and enrolled in these three programs for the years 2001 and 2002 and graduating in the years 2003 and 2004 (N = 195). The categorical dependent variable was attrition (includes academic failure or withdrawal) from the program of nursing education. The ten independent variables selected for the study and considered to have possible predictive value were: Grade Point Average for Pre-requisite Course Work; ACT Composite Score, ACT Reading Subscore, and ACT Mathematics Subscore; Letter Grades in the Courses: Anatomy & Physiology and Lab I, Algebra I, English I (101), Chemistry & Lab I, and Microbiology & Lab I; and Number of Institutions Attended (Universities, Colleges, Junior Colleges or Community Colleges). Descriptive analysis was performed and the means of each of the ten independent variables was compared for students who attrited and those who were retained in the population. The discriminant statistical analysis performed created a matrix using the ten variable model that was able to correctly predicted attrition in the study's population in 77.6% of the cases. Variables were then combined and recombined to produce the most efficient and parsimonious model for prediction. A six variable model resulted which weighted each variable according to predictive value: GPA for Prerequisite Coursework, ACT Composite, English I, Chemistry & Lab I, Microbiology & Lab I, and Number of Institutions Attended. Results of the study indicate that it is possible to predict attrition among students enrolled in baccalaureate nursing education programs and that additional investigation on the subject is warranted.

In this study, I conducted focus group interviews with 21 Arab American college students (9 men, 12 women; 9 Muslims, 12 non-Muslims), who were selected for extreme manifestation of religiosity or acculturation, to explore their beliefs and attitudes toward socioecological (SE) factors that facilitated and hindered their individual physical activity (PA) and body composition (I also considered body image and food and eating behavior). To analyze responses, I used a combination of deductive coding, which used levels of the SE model and demographic variable groupings, and inductive coding, to search for common themes among participants within and between research questions. Results revealed that (a) the context of physical activity participation differed by gender; (b) ideal body image was conflicted and varied by gender; and (c) consumption of cultural foods diminished along with Arab social customs related to eating. Interpersonal and cultural/community levels of the SE model were identified as primary influences, with parents regulating and instilling values backed by cultural norms to preserve Arab identity, especially in women. Finally, I identified an indeterminate adjustment period, during which immigrants transitioned between physical activity purpose/form in the Middle East and the United States.

Student Performance on Conceptual Questions: Does Instruction Matter?
NASA Astrophysics Data System (ADS)
Heron, Paula
2012-10-01
As part of the tutorial component of introductory calculus-based physics at the University of Washington, students take weekly pretests that consist of conceptual questions. Pretests are so named because they precede each tutorial, but they are frequently administered after lecture instruction. Many variables associated with class composition and prior instruction could, in principle, affect student performance. Nonetheless, the results are often found to be ``essentially the same'' in all classes. Selected questions for which we have accumulated thousands of responses, from dozens of classes representing different conditions with respect to the textbook in use, the amount of prior instruction, etc., serve as examples. A preliminary analysis suggests that the variation in performance across all classes is essentially random. No statistically significant difference is observed between results obtained before relevant instruction begins and after it has been completed. The results provide evidence that exposure to concepts in lecture and textbook is not sufficient to ensure an improvement in performance on questions that require qualitative reasoning.

Six Classroom Exercises to Teach Natural Selection to Undergraduate Biology Students
Kalinowski, Steven T.; Leonard, Mary J.; Andrews, Tessa M.; Litt, Andrea R.
2013-01-01
Students in introductory biology courses frequently have misconceptions regarding natural selection. In this paper, we describe six activities that biology instructors can use to teach undergraduate students in introductory biology courses how natural selection causes evolution. These activities begin with a lesson introducing students to natural selection and also include discussions on sexual selection, molecular evolution, evolution of complex traits, and the evolution of behavior. The set of six topics gives students the opportunity to see how natural selection operates in a variety of contexts. Pre- and postinstruction testing showed students’ understanding of natural selection increased substantially after completing this series of learning activities. Testing throughout this unit showed steadily increasing student understanding, and surveys indicated students enjoyed the activities. PMID:24006396

To explore the trend and composition of post-graduate Iranian students who received governmental scholarship during the last two decades. Detailed information about the awarded scholarships and also about the number of post graduate students in clinical and basic sciences in domestic universities were collected from the related offices within the ministry of health and medical education and their trends were triangulated. A sharp drop was observed in the number of awarded scholarships, from 263 in 1992 to 46 in 2009. In the beginning, almost all of scholarships fully supported students for a whole academic course; while in recent years most of scholarships supported students for a short fellowship or complementary course (more than 80%). Students studied in a wide range of colleges within 30 countries; more than 50% in Europe. Although one third of students studied in UK in the first years, only 4% of students selected this country in recent years. conversely, the number of scholarships to Germany and sweden have increased more than 10 and 3 times during this period. In parallel, the capacity of domestic universities for training of post-graduate students has been expanded dramatically. Although expanding post-graduate education has been one of the main strategic objectives of the ministry of health and medical education in last two decades, it was obtained using different approaches. By time, more attention was to expanding the capacities of Iranian universities, and choosing less but more targeted students to continue their studies abroad.

Effects of medical school selection on student motivation: a PhD thesis report.
Wouters, Anouk
2018-02-01
High stakes are involved in student selection, for both medical schools and applicants. This thesis investigated the effects of selection on the medical student population and applicant pool in the Dutch setting. This thesis consists of six papers: two quantitative studies, one qualitative study, two mixed methods studies and one perspective paper based on a review of the literature. (1) Compared with a lottery, selection does not result in a student population with better motivation, engagement and performance, both in the clinical and pre-clinical phases of the study. (2) Selection seems to have a temporary stimulating effect on student motivation through enhancing perceived autonomy, competence and relatedness. (3) Applicants adopt a strategic approach, based on the selection procedure, in their choice of medical school. (4) The description of an applicant's motivation is not a reliable and valid tool to assess motivation during selection. (5) Gaining healthcare experience is crucial for applicants' motivation, but inequalities in access to such experiences can demotivate certain student groups from applying to medical school. (6) The gains yielded from selection compared with a lottery seem to be small. Unintentionally induced self-selection among certain groups of students and biased selection procedures may compromise student diversity. The added value of selection procedures compared with a weighted lottery for admitting students to medical school is questionable. Students are generally motivated and perform well, irrespective of how they enrolled in medical school. Selection yields only small gains, while student diversity may be hampered.

Early clinical skills teaching often requires students to learn through examining one another. This model should acknowledge ethical, practical and individual issues, disclosure and identification of abnormalities. Consent to peer physical examination (PPE) is usually expected rather than discussed and sought. We sought to evaluate a formal written consent process for PPE and to explore students' views of this approach. A survey tool was designed and distributed to all years 2 and 3 students in the Auckland University medical programme (2004). Results were analysed using univariate statistics and thematic analysis. The response rate was 57% (146/258). Most students had read the participant information sheet prior to signing, with 78% giving consent. They had not felt coerced and the in-course experience matched the 'promise'. Comments included: PPE gave insights into the 'patient's world', encouraged peer learning and raised some professional issues. More than 95% of students took the examination role at least once (less likely if female, P = 0.002). Some European, Maori and Pacific students never took the role; all Asian students did at least once. Students preferred PPE in groups consisting of 'friends'. The task influenced group composition by sex (P < 0.0001) but not ethnicity. Students accept and support a formal consent process. PPE participation rates are similar to predictions. The experience must match the promises made. Formal preparation alone might have produced similar student outcomes. Female students are more selective about tasks undertaken. The influence of ethnicity and the effect on future behaviour and attitudes needs further exploration.
A Discriminant Distance Based Composite Vector Selection Method for Odor Classification
Choi, Sang-Il; Jeong, Gu-Min
2014-01-01
We present a composite vector selection method for an effective electronic nose system that performs well even in noisy environments. Each composite vector generated from a electronic nose data sample is evaluated by computing the discriminant distance. By quantitatively measuring the amount of discriminative information in each composite vector, composite vectors containing informative variables can be distinguished and the final composite features for odor classification are extracted using the selected composite vectors. Using the only informative composite vectors can be also helpful to extract better composite features instead of using all the generated composite vectors. Experimental results with different volatile organic compound data show that the proposed system has good classification performance even in a noisy environment compared to other methods.

Background This study investigated changes in student food selection and consumption in response to the new National School Lunch Program meal patterns during fall, 2011. Design Eight elementary and four intermediate schools in one Houston area school district were matched on free/reduced price (FRP) meal eligibility and randomized into control or intervention conditions. Intervention Both intervention and control school cafeterias served the same menu. The intervention school cafeterias posted the new meal pattern daily; students could select one fruit and two vegetable servings per reimbursable meal. Control school students could only select the previous meal pattern: a total of two fruit and vegetable servings per meal. Main outcome measures Students were observed during lunch: gender, foods selected/consumed were recorded. Diet analysis software was used to calculate energy/food groups selected/consumed. Statistical analyses performed Cochran-Mantel-Haenszel Chi-square tests examined differences in the percent of students selecting each meal component by condition, controlling for gender, grade, and school FRP. ANCOVA assessed differences in amount of energy/food groups selected and consumed, and differences in percent of food groups consumed. Results Observations were conducted for 1149 elementary and 427 intermediate students. Compared with students in the control schools, significantly more intervention elementary and intermediate school students selected total (P<0.001, P<0.05) and starchy vegetables (P<0.001; P<0.01); more intervention intermediate school students selected fruit (P<0.001), legumes (P<0.05), and protein foods (P<0.01). There were significantly greater amounts of these foods selected and consumed, but no differences in the proportion of the foods consumed by condition. Fewer calories were consumed by elementary and intermediate school intervention students. Conclusions More intervention students selected fruit and vegetables at lunch, and consumed them compared with control condition students. Future studies with larger and more diverse student populations are warranted. PMID:25556770
Longitudinal predictors of high school completion.
Barry, Melissa; Reschly, Amy L
2012-06-01
This longitudinal study examined predictors of dropout assessed in elementary school. Student demographic data, achievement, attendance, and ratings of behavior from the Behavior Assessment System for Children were used to predict dropout and completion. Two models, which varied on student sex and race, predicted dropout at rates ranging from 75% to 88%. Model A, which included the Behavioral Symptoms Index, School Problems composite, Iowa Tests of Basic Skills battery, and teacher ratings of student work habits, best predicted female and African American dropouts. Model B, which comprised the Adaptive Skills composite, the Externalizing composite, the School Problems composite, referral for a student support team meeting, and sex, was more accurate for predicting Caucasian dropouts. Both models demonstrated the same hit rates for predicting male dropouts. Recommendations for early warning indicators and linking predictors with interventions are discussed.

The purpose of this study was to examine the relationship and predictive power of the variables gender, high school GPA, class rank, SAT scores, ACT scores, and socioeconomic status on the graduation rates of minority college students majoring in the sciences at a selected urban university. Data was examined on these variables as they related to minority students majoring in science. The population consisted of 101 minority college students who had majored in the sciences from 1986 to 1996 at an urban university in the southwestern region of Texas. A non-probability sampling procedure was used in this study. The non-probability sampling procedure in this investigation was incidental sampling technique. A profile sheet was developed to record the information regarding the variables. The composite scores from SAT and ACT testing were used in the study. The dichotomous variables gender and socioeconomic status were dummy coded for analysis. For the gender variable, zero (0) indicated male, and one (1) indicated female. Additionally, zero (0) indicated high SES, and one (1) indicated low SES. Two parametric procedures were used to analyze the data in this investigation. They were the multiple correlation and multiple regression procedures. Multiple correlation is a statistical technique that indicates the relationship between one variable and a combination of two other variables. The variables socioeconomic status and GPA were found to contribute significantly to the graduation rates of minority students majoring in all sciences when combined with chemistry (Hypotheses Two and Four). These variables accounted for 7% and 15% of the respective variance in the graduation rates of minority students in the sciences and in chemistry. Hypotheses One and Three, the predictor variables gender, high school GPA, SAT Total Scores, class rank, and socioeconomic status did not contribute significantly to the graduation rates of minority students in biology and pharmacy.

Friendship Concept and Community Network Structure among Elementary School and University Students.

We use complex network theory to study the differences between the friendship concepts in elementary school and university students. Four friendship networks were identified from surveys. Three of these networks are from elementary schools; two are located in the rural area of Yucatán and the other is in the urban area of Mérida, Yucatán. We analyzed the structure and the communities of these friendship networks and found significant differences among those at the elementary schools compared with those at the university. In elementary schools, the students make friends mainly in the same classroom, but there are also links among different classrooms because of the presence of siblings and relatives in the schools. These kinds of links (sibling-friend or relative-friend) are called, in this work, "mixed links". The classification of the communities is based on their similarity with the classroom composition. If the community is composed principally of students in different classrooms, the community is classified as heterogeneous. These kinds of communities appear in the elementary school friendship networks mainly because of the presence of relatives and siblings. Once the links between siblings and relatives are removed, the communities resembled the classroom composition. On the other hand, the university students are more selective in choosing friends and therefore, even when they have friends in the same classroom, those communities are quite different to the classroom composition. Also, in the university network, we found heterogeneous communities even when the presence of sibling and relatives is negligible. These differences made up a topological structure quite different at different academic levels. We also found differences in the network characteristics. Once these differences are understood, the topological structure of the friendship network and the communities shaped in an elementary school could be predicted if we know the total number of students and the ties between siblings and relatives. However, at the university, we cannot do the same. This discovery implies that friendship is a dynamic concept that produces several changes in the friendship network structure and the way that people make groups of friends; it provides the opportunity to give analytic support to observational studies. Communities were also studied by gender and we found that when the links among relatives and siblings were removed, the number of communities formed by one gender alone increased. At the university, many communities formed by students of the same gender were also found.

Medical schools seek ways to improve their admissions strategies, since the available methods prove to be suboptimal for selecting the best and most motivated students. In this multi-site cross-sectional questionnaire study, we examined the value of (different) selection procedures compared to a weighted lottery procedure, which includes direct admission based on top pre-university grade point averages (≥8 out of 10; top-pu-GPA). We also considered whether students had participated in selection, prior to being admitted through weighted lottery. Year-1 (pre-clinical) and Year-4 (clinical) students completed standard validated questionnaires measuring quality of motivation (Academic Self-regulation Questionnaire), strength of motivation (Strength of Motivation for Medical School-Revised) and engagement (Utrecht Work Engagement Scale-Student). Performance data comprised GPA and course credits in Year-1 and clerkship performance in Year-4. Regression analyses were performed. The response rate was 35% (387 Year-1 and 273 Year-4 students). Top-pu-GPA students outperformed selected students. Selected Year-1 students reported higher strength of motivation than top-pu-GPA students. Selected students did not outperform or show better quality of motivation and engagement than lottery-admitted students. Participation in selection was associated with higher engagement and better clerkship performance in Year-4. GPA, course credits and strength of motivation in Year-1 differed between students admitted through different selection procedures. Top-pu-GPA students perform best in the medical study. The few and small differences found raise questions about the added value of an extensive selection procedure compared to a weighted lottery procedure. Findings have to be interpreted with caution because of a low response rate and small group sizes.
Selection as a learning experience: an exploratory study.

Research on selection for medical school does not explore selection as a learning experience, despite growing attention for the learning effects of assessment in general. Insight in the learning effects allows us to take advantage of selection as an inclusive part of medical students' learning process to become competent professionals. The aims of this study at Radboud University Medical Center, the Netherlands, were 1) to determine whether students have learning experiences in the selection process, and, if so, what experiences; and 2) to understand what students need in order to utilize the learning effects of the selection process at the start of the formal curriculum. We used focus groups to interview 30 students admitted in 2016 about their learning experiences in the selection process. Thematic analysis was used to explore the outcomes of the interviews and to define relevant themes. In the selection process, students learned about the curriculum, themselves, their relation to others, and the profession they had been selected to enter, although this was not explicitly perceived as learning. Students needed a connection between selection and the curriculum as well as feedback to be able to really use their learning experiences for their further development. Medical school selection qualifies as a learning experience, and students as well as medical schools can take advantage of this. We recommend a careful design of the selection procedure, integrating relevant selection learning experiences into the formal curriculum, providing feedback and explicitly approaching the selection and the formal curriculum as interconnected contributors to students' development.

Predicting workplace performance of junior doctors from before entry or during medical school is difficult and has limited available evidence. This study explored the association between selected predictor variables and workplace based performance in junior doctors during their first postgraduate year. Two cohorts of medical students (n = 200) from one university in Western Australia participated in the longitudinal study. Pearson correlation coefficients and multivariate analyses utilizing linear regression were used to assess the relationships between performance on the Junior Doctor Assessment Tool (JDAT) and its sub-components with demographic characteristics, selection scores for medical school entry, emotional intelligence, and undergraduate academic performance. Grade Point Average (GPA) at the completion of undergraduate studies had the most significant association with better performance on the overall JDAT and each subscale. Increased age was a negative predictor for junior doctor performance on the Clinical management subscale and understanding emotion was a predictor for the JDAT Communication subscale. Secondary school performance measured by Tertiary Entry Rank on entry to medical school score predicted GPA but not junior doctor performance. The GPA as a composite measure of ability and performance in medical school is associated with junior doctor assessment scores. Using this variable to identify students at risk of difficulty could assist planning for appropriate supervision, support, and training for medical graduates transitioning to the workplace.

Background: To explore the trend and composition of post-graduate Iranian students who received governmental scholarship during the last two decades. Method: Detailed information about the awarded scholarships and also about the number of post graduate students in clinical and basic sciences in domestic universities were collected from the related offices within the ministry of health and medical education and their trends were triangulated. Results: A sharp drop was observed in the number of awarded scholarships, from 263 in 1992 to 46 in 2009. In the beginning, almost all of scholarships fully supported students for a whole academic course; while in recent years most of scholarships supported students for a short fellowship or complementary course (more than 80%). Students studied in a wide range of colleges within 30 countries; more than 50% in Europe. Although one third of students studied in UK in the first years, only 4% of students selected this country in recent years. conversely, the number of scholarships to Germany and sweden have increased more than 10 and 3 times during this period. In parallel, the capacity of domestic universities for training of post-graduate students has been expanded dramatically. Conclusion: Although expanding post-graduate education has been one of the main strategic objectives of the ministry of health and medical education in last two decades, it was obtained using different approaches. By time, more attention was to expanding the capacities of Iranian universities, and choosing less but more targeted students to continue their studies abroad. PMID:23865032

A multi-institution collaborative team of Australian chemistry education researchers, teaching a total of over 3000 first year chemistry students annually, has explored a tool for diagnosing students' prior conceptions as they enter tertiary chemistry courses. Five core topics were selected and clusters of diagnostic items were assembled linking related concepts in each topic together. An ordered multiple choice assessment strategy was adopted to enable provision of formative feedback to students through combination of the specific distractors that they chose. Concept items were either sourced from existing research instruments or developed by the project team. The outcome is a diagnostic tool consisting of five topic clusters of five concept items that has been delivered in large introductory chemistry classes at five Australian institutions. Statistical analysis of data has enabled exploration of the composition and validity of the instrument including a comparison between delivery of the complete 25 item instrument with subsets of five items, clustered by topic. This analysis revealed that most items retained their validity when delivered in small clusters. Tensions between the assembly, validation and delivery of diagnostic instruments for the purposes of acquiring robust psychometric research data versus their pragmatic use are considered in this study.

Students in OU's Geology and Geophysics (G&G) program must complete either English Technical Writing or a major-specific Geowriting class as sophomores or juniors. We asked students in Geowriting and students in a G&G colloquium course (required for G&G scholarship students and an elective for others) to complete surveys reporting their writing experiences and attitudes, as well as write an abstract for a Scientific American story to assess writing skills at the beginning and end of the semester. Geowriting students had stronger writing skills and more positive attitudes towards writing at the beginning of the semester than their colloquium peers, suggesting that students who were already interested and skilled in writing were self-selecting into the class. During the semester, Geowriting focused on improving the clarity, organization, efficiency, and mechanics of student writing and discussed how science writing is similar in some ways (argument, sentence structure, etc.), but also different in many aspects (concise, forthright, repetitive, etc) from writing tactics taught in high school and some college composition courses. Colloquium students attended the weekly scientific talks, but did not write in the class; however, some students were enrolled in freshman-level composition courses and Technical Writing. End-of-semester surveys showed Geowriting students had a more positive change in attitude and expectations towards writing than their colloquium peers. However, one significant difference in attitude towards writing was indicated by negative feelings towards in-class writing, which may be a result of 'writing fatigue' within the Geowriting group. This writing fatigue could be explained by student end-of -semester cognitive overload. Through other measures, colloquium students showed a greater improvement in writing skills (concise, clear, organized, etc) compared to Geowriting students; however, Geowriting students maintained higher skill levels than the Colloquium group at the end of the semester. Geowriting students reported in self-assessments that they had 're-learned' how to write as geoscientists in the class and had developed new writing tactics that they could apply to writing projects in other science courses. Based on these reports, we assessed abstract samples to determine if students were employing commonly taught prose style techniques (catchy intro, final summary statement, etc.), which are not usually appropriate in abstracts. Results show that Geowriting students used fewer prose style techniques at the end of the semester, resulting in more professional abstracts, while Colloquium students used more prose style techniques compared to the initial sample, resulting in less appropriate writing for the genre. In other words, Colloquium students may have lacked an explicit introduction to the genre conventions of abstracts and thus relied on a familiar genre and its stylistic devices. These results highlight the effectiveness of science-specific writing instruction within the major to guide students into the norms of the geoscience discourse community and help students learn how to 'write like a geoscientist.' However, as an elective course, only students already interested and skilled in writing were affected.

Dental restorative materials are color matched to the tooth and are difficult to remove by mechanical means without excessive removal or damage to peripheral enamel and dentin. Lasers are ideally suited for selective ablation to minimize healthy tissue loss when replacing existing restorations, sealants or removing composite adhesives such as residual composite left after debonding orthodontic brackets. In this study a carbon dioxide laser operating at high laser pulse repetition rates integrated with a galvanometer based scanner was used to selectively remove composite from tooth surfaces. A diode array spectrometer was used to measure the plume emission after each laser pulse and determine if the ablated material was tooth mineral or composite. The composite was placed on tooth buccal and occlusal surfaces and the carbon dioxide laser was scanned across the surface to selectively remove the composite without excessive damage to the underlying sound enamel. The residual composite and the damage to the underlying enamel was evaluated using optical microscopy. The laser was able to rapidly remove the composites rapidly from both surfaces with minimal damage to the underlying sound enamel.

The purpose of this study was to determine the effect of an 11th-grade and 12th-grade zoo-based academic high school experiential science program compared to a same school-district school-based academic high school experiential science program on students' pretest and posttest science, math, and reading achievement, and student perceptions of program relevance, rigor, and relationships. Science coursework delivery site served as the study's independent variable for the two naturally formed groups representing students (n = 18) who completed a zoo-based experiential academic high school science program and students (n = 18) who completed a school-based experiential academic high school science program. Students in the first group, a zoo-based experiential academic high school science program, completed real world, hands-on projects at the zoo while students in the second group, those students who completed a school-based experiential academic high school science program, completed real world, simulated projects in the classroom. These groups comprised the two research arms of the study. Both groups of students were selected from the same school district. The study's two dependent variables were achievement and school climate. Achievement was analyzed using norm-referenced 11th-grade pretest PLAN and 12th-grade posttest ACT test composite scores. Null hypotheses were rejected in the direction of improved test scores for both science program groups---students who completed the zoo-based experiential academic high school science program (p < .001) and students who completed the school-based experiential academic high school science program (p < .001). The posttest-posttest ACT test composite score comparison was not statistically different ( p = .93) indicating program equipoise for students enrolled in both science programs. No overall weighted grade point average score improvement was observed for students in either science group, however, null hypotheses were rejected in the direction of improved science grade point average scores for 11th-grade (p < .01) and 12th-grade (p = .01) students who completed the zoo-based experiential academic high school science program. Null hypotheses were not rejected for between group posttest science grade point average scores and school district criterion reference math and reading test scores. Finally, students who completed the zoo-based experiential academic high school science program had statistically improved pretest-posttest perceptions of program relationship scores (p < .05) and compared to students who completed the school-based experiential academic high school science program had statistically greater posttest perceptions of program relevance (p < .001), perceptions of program rigor (p < .001), and perceptions of program relationships (p < .001).

An Automated Summarization Assessment Algorithm for Identifying Summarizing Strategies
Abdi, Asad; Idris, Norisma; Alguliyev, Rasim M.; Aliguliyev, Ramiz M.
2016-01-01
Background Summarization is a process to select important information from a source text. Summarizing strategies are the core cognitive processes in summarization activity. Since summarization can be important as a tool to improve comprehension, it has attracted interest of teachers for teaching summary writing through direct instruction. To do this, they need to review and assess the students' summaries and these tasks are very time-consuming. Thus, a computer-assisted assessment can be used to help teachers to conduct this task more effectively. Design/Results This paper aims to propose an algorithm based on the combination of semantic relations between words and their syntactic composition to identify summarizing strategies employed by students in summary writing. An innovative aspect of our algorithm lies in its ability to identify summarizing strategies at the syntactic and semantic levels. The efficiency of the algorithm is measured in terms of Precision, Recall and F-measure. We then implemented the algorithm for the automated summarization assessment system that can be used to identify the summarizing strategies used by students in summary writing. PMID:26735139

Childhood obesity and hypertension are global problems that are on the rise in India. Improving physical activity is an accepted main line of strategy for overcoming poor body composition, hypertension and reduced cardio respiratory fitness (CRF) all of which are considered as independent risk factors for the development of future cardiovascular complications. Present study was conducted to evaluate the effect of regular unstructured physical training and athletic level training on anthropometric measures, body composition, blood pressure and cardio respiratory fitness in adolescents. This is a collaborative study between the Department of physiology, Jawaharlal Institute of Postgraduate Medical Education and Research and Residential school, Jawahar Navodhya Vidyalaya, Puducherry, India. Student volunteers in the age group of 12-17 years were classified into athletes (group 1) and physically active non-athletes (group 2). Parameters measured and calculated were weight, height, body mass index, waist and hip circumference, body fat percentage (BF%), fat free mass (FFM), Systolic (SBP) & Diastolic blood pressure (DBP), Mean arterial pressure (MAP), Rate pressure product (RPP) and Predicted VO2 max. Mean difference between the groups was analysed using unpaired Student's t-test. All statistical analysis was carried out for two-tailed significance at the 5 % level using SPSS version 19 (SPSSInc, USA). Anthropometric measures, body composition measures and blood pressure values of both the group students were within the normal limits. There was no significant difference in anthropometric and body composition parameters between the group 1 and group 2 students. DBP, MAP and RPP were significantly lower in group 1 students when compared to group 2 students. VO2 max values were more in group 1 girls as compared to group 2 girls while the values of boys were comparable between the two groups. Regular unstructured physical activity for 60 minutes daily for the duration of one year can help the students to maintain their anthropometric parameters, body composition measures and CRF at par with the athletes of the same age and gender. However, athletic level training further reduces the cardiovascular load of the adolescent students.

Using marketing research concepts to investigate specialty selection by medical students.
Weissman, Charles; Schroeder, Josh; Elchalal, Uriel; Weiss, Yoram; Tandeter, Howard; Zisk-Rony, Rachel Y
2012-10-01
This study was intended to examine whether a marketing research approach improves understanding of medical specialty selection by medical students. This approach likens students to consumers who are deciding whether or not to purchase a product (specialty). This approach proposes that when consumers' criteria match their perceptions of a product's features, the likelihood that they will purchase it (select the specialty) increases. This study examines whether exploring students' selection criteria and perceptions of various specialties provides additional insights into the selection process. Using a consumer behaviour model as a framework, a questionnaire was designed and administered to Year 6 (final-year) students in 2008 and 2009 to elicit information on their knowledge about and interests in various specialties, the criteria they used in specialty selection, and their perceptions of six specialties. A total of 132 (67%) questionnaires were returned. In many instances, consistency between selection criteria and perceptions of a specialty was accompanied by interest in pursuing the specialty. Exceptions were noted and pointed to areas requiring additional research. For example, although > 70% of female students replied that the affordance of a controllable lifestyle was an important selection criterion, many were interested in obstetrics and gynaecology despite the fact that it was not perceived as providing a controllable lifestyle. Minimal overlap among students reporting interest in primary specialties that possess similar characteristics (e.g. paediatrics and family medicine) demonstrated the need to target marketing (recruitment) efforts for each specialty individually. Using marketing research concepts to examine medical specialty selection may precipitate a conceptual shift among health care leaders which acknowledges that, to attract students, specialties must meet students' selection criteria. Moreover, if consumers (students) deem a product (specialty) unattractive, it may need to be examined further to improve its appeal. © Blackwell Publishing Ltd 2012.

The main purpose of the institution is to provide quality education to the students and to improve the quality of managerial decisions. One of the ways to improve the quality of students is to arrange the selection of new students with a more selective. This research takes the case in the selection of new students at Islamic University of Indonesia, Yogyakarta, Indonesia. One of the university's selection is through filtering administrative selection based on the records of prospective students at the high school without paper testing. Currently, that kind of selection does not yet has a standard model and criteria. Selection is only done by comparing candidate application file, so the subjectivity of assessment is very possible to happen because of the lack standard criteria that can differentiate the quality of students from one another. By applying data mining techniques classification, can be built a model selection for new students which includes criteria to certain standards such as the area of origin, the status of the school, the average value and so on. These criteria are determined by using rules that appear based on the classification of the academic achievement (GPA) of the students in previous years who entered the university through the same way. The decision tree method with C4.5 algorithm is used here. The results show that students are given priority for admission is that meet the following criteria: came from the island of Java, public school, majoring in science, an average value above 75, and have at least one achievement during their study in high school.

Past research on ethnic composition effects on migrant and ethnic majority students' performance has reported inconclusive results: Some studies have found no relationship between the proportion of migrant students in school and students' performance, some revealed positive effects, whereas others showed negative effects of the proportion of migrant students. Most of the studies did not consider whether an increase in the proportion of migrant students in the classroom has different effects on migrant and ethnic majority students' performance. For this reason, the present study (N = 9215) extends previous research by investigating the cross-level interaction effect of the proportion of Turkish-origin students in classrooms on Turkish-origin and German students' reading performance with data based on the German National Assessment Study 2008/2009 in the school subject German. In addition, we examined the cross-level interaction effect of Turkish-origin students' proportion on sense of belonging to school for Turkish-origin and German students, as sense of belonging has been shown to be an important predictor of well-being and integration. No cross-level interaction effect on performance emerged. Only a small negative main effect of the Turkish-origin students' proportion on all students' performance was found. As predicted, we showed a cross-level interaction on sense of belonging. Only Turkish-origin students' sense of belonging was positively related to the proportion of Turkish-origin students: The more Turkish-origin students there were in a classroom, the higher Turkish-origin students' sense of belonging. German students' sense of belonging was not related to the ethnic classroom composition. Implications of the results in the educational context are discussed. PMID:27471484

First-generation students' underperformance at university: the impact of the function of selection.
Jury, Mickaël; Smeding, Annique; Darnon, Céline
2015-01-01
According to recent research, university not only has the role to educate and train students, it also has the role to select the best students. We argue that this function of selection disadvantages first-generation students, in comparison with continuing-generation students. Thus, the mere activation of the function of selection should be sufficient to produce achievement differences between first-generation and continuing-generation students in a novel academic task. Furthermore, we propose that when the function of selection is salient, first-generation students would be more vigilant to a cue that may confirm their inferiority, which should explain their underperformance. In the present experiment, participants were asked to complete an arithmetic modular task under two conditions, which either made the function of selection salient or reduced its importance. Participants' vigilance to a threatening cue (i.e., their performance relative to others) was measured through an eye-tracking technique. The results confirmed that first-generation students performed more poorly compared to continuing-generation students only when the function of selection was salient while no differences appeared in the no-selection condition. Regarding vigilance, the results did not confirm our hypothesis; thus, mediation path could not be tested. However, results indicated that at a high level of initial performance, first-generation students looked more often at the threatening cue. In others words, these students seemed more concerned about whether they were performing more poorly than others compared to their continuing-generation counterparts. Some methodological issues are discussed, notably regarding the measure of vigilance.

Selection of medical students at South African (SA) medical schools must promote equitable and fair access to students from all population groups, while ensuring optimal student throughput and success, and training future healthcare practitioners who will fulfil the needs of the local society. In keeping with international practices, a variety of academic and non-academic measures are used to select applicants for medical training programmes in SA medical schools. To provide an overview of the selection procedures used by all eight medical schools in SA, and the student demographics (race and gender) at these medical schools, and to determine to what extent collective practices are achieving the goals of student diversity and inclusivity. A retrospective, quantitative, descriptive study design was used. All eight medical schools in SA provided information regarding selection criteria, selection procedures, and student demographics (race and gender). Descriptive analysis of data was done by calculating frequencies and percentages of the variables measured. Medical schools in SA make use of academic and non-academic criteria in their selection processes. The latter include indices of socioeconomic disadvantage. Most undergraduate medical students in SA are black (38.7%), followed by white (33.0%), coloured (13.4%) and Indian/Asian (13.6%). The majority of students are female (62.2%). The number of black students is still proportionately lower than in the general population, while other groups are overrepresented. Selection policies for undergraduate medical programmes aimed at redress should be continued and further refined, along with the provision of support to ensure student success.

Does a selection interview predict year 1 performance in dental school?
McAndrew, R; Ellis, J; Valentine, R A

It is important for dental schools to select students who will complete their degree and progress on to become the dentists of the future. The process should be transparent, fair and ethical and utilise selection tools that select appropriate students. The interview is an integral part of UK dental schools student selection procedures. This study was undertaken in order to determine whether different interview methods (Cardiff with a multiple mini interview and Newcastle with a more traditional interview process) along with other components used in selection predicted academic performance in students. The admissions selection data for two dental schools (Cardiff and Newcastle) were collected and analysed alongside student performance in academic examinations in Year 1 of the respective schools. Correlation statistics were used to determine whether selection tools had any relevance to academic performance once students were admitted to their respective Universities. Data was available for a total of 177 students (77 Cardiff and 100 Newcastle). Examination performance did not correlate with admission interview scores at either school; however UKCAT score was linked to poor academic performance. Although interview methodology does not appear to correlate with academic performance it remains an integral and very necessary part of the admissions process. Ultimately schools need to be comfortable with their admissions procedures in attracting and selecting the calibre of students they desire. © 2016 John Wiley & Sons A/S.

Yi, Ivana; Chan, Kenneth H.; Tsuji, Grant H.; Staninec, Michal; Darling, Cynthia L.; Fried, Daniel
2016-02-01
Dental composites are used for a wide range of applications such as fillings for cavities, adhesives for orthodontic brackets, and closure of gaps (diastemas) between teeth by esthetic bonding. Anterior restorations are used to replace missing, diseased and unsightly tooth structure for both appearance and function. When these restorations must be replaced, they are difficult to remove mechanically without causing excessive removal or damage to enamel because dental composites are color matched to teeth. Previous studies have shown that CO2 lasers have high ablation selectivity and are well suited for removal of composite on occlusal surfaces while minimizing healthy tissue loss. A spectral feedback guidance system may be used to discriminate between dental composite and dental hard tissue for selective ablation of composite material. The removal of composite restorations filling diastemas is more challenging due to the esthetic concern for anterior teeth. The objective of this study is to determine if composite spanning a diastema between anterior teeth can be removed by spectral guided laser ablation at clinically relevant rates with minimal damage to peripheral healthy tissue and with higher selectivity than a high speed dental handpiece.
Pharmacy Student Performance on Constructed-Response Versus Selected-Response Calculations Questions

2013-01-01
Objective. To introduce PharmD students to changes in calculations question types (constructed-response versus selected-response questions); measure and compare student performance on constructed-response and selected-response questions in a pharmaceutics course; and collect student feedback on the use of differing question types. Methods A pharmaceutics/pharmaceutical calculations examination was administered that included 15 pairs of questions; each pair consisted of a constructed-response question and a similar selected-response question. An online questionnaire was conducted to collect student feedback. Results. Of the 15 topics, the class scored higher on the constructed-response question for 4 topics and higher on the selected-response question for 10 topics. Eighty percent of the class preferred selected-response questions, although 47.8% felt constructed-response questions better prepared them for a career in healthcare. Conclusions. Students correctly answered more selected-response questions than constructed-response questions and felt more confident in doing so. Additional constructed-response teaching and testing methods should be incorporated into pharmacy education. PMID:23459503
Selected medical students achieve better than lottery-admitted students during clerkships.

A recent controlled study by our group showed that the dropout rate in the first 2 years of study of medical students selected for entry by the assessment of a combination of non-cognitive and cognitive abilities was 2.6 times lower than that of a control group of students admitted by lottery. The aim of the present study was to compare the performance of these two groups in the clinical phase. A prospective cohort study was performed to compare the performance of 389 medical students admitted by selection with that of 938 students admitted by weighted lottery between 2001 and 2004. Follow-up of these cohorts lasted 5.5-8.5 years. The main outcome measures were the mean grade obtained on the first five discipline-specific clerkships by all cohorts and the mean grade achieved on all 10 clerkships by the cohorts of 2001 and 2002. Selected students obtained a significantly higher mean grade during their first five clerkships than lottery-admitted students (mean ± standard error [SE] 7.95 ± 0.03, 95% confidence interval [CI] 7.90-8.00 versus mean ± SE 7.84 ± 0.02, 95% CI 7.81-7.87; p < 0.001). This difference reflected the fact that selected students achieved a grade of ≥ 8.0 1.5 times more often than lottery-admitted students. An analysis of all mean grades awarded on 10 clerkships revealed the same results. Moreover, the longer follow-up period over the clerkships showed that the relative risk for dropout was twice as low in the selected student group as in the lottery-admitted student group. The selected group received significantly higher mean grades on their first five clerkships, which could not be attributed to factors other than the selection procedure. Although the risk for dropout before the clinical phase increased somewhat in both groups, the actual dropout rate proved to be twice as low in the selected group. © Blackwell Publishing Ltd 2011.

Schools are one of the strongest socializing forces in the U.S. and wield considerable influence over individuals' social and economic trajectories. Our study investigates how school-level racial composition, measured by the percentage non-Hispanic white students in a school, affects depressive and somatic symptoms among a representative sample of U.S. adolescents, and whether the association differs by race/ethnicity. We analyzed Wave I data from the US National Longitudinal Study of Adolescent Health, resulting in a sample size of 18,419 students attending 132 junior and senior high schools in 1994/5. After controlling for individual and school characteristics, our multilevel analyses indicated that with increasing percentages of white students at their school, black students experienced more depressive symptoms and a higher risk of reporting high levels of somatic symptoms. After including students' perceptions of discrimination and school attachment, the interaction between black student race and school-level racial composition was no longer significant for either outcome. Our findings suggest that attending predominantly-minority schools may buffer black students from discrimination and increase their school attachment, which may reduce their risk of experiencing depressive and somatic symptoms.

Objective Dental composite restorative materials are color matched to the tooth and are difficult to remove by mechanical means without excessive removal or damage to peripheral enamel and dentin. Lasers are ideally suited for selective ablation to minimize healthy tissue loss when replacing existing restorations, sealants, or removing composite adhesives such as residual composite left after debonding orthodontic brackets. Methods In this study, a carbon dioxide laser operating at 9.3-μm with a pulse duration of 10–20-microsecond and a pulse repetition rate of ~200 Hz was integrated with a galvanometer based scanner and used to selectively remove composite from tooth surfaces. Spectra of the plume emission were acquired after each laser pulse and used to differentiate between the ablation of dental enamel or composite. Microthermocouples were used to monitor the temperature rise in the pulp chamber during composite removal. The composite was placed on tooth buccal and occlusal surfaces and the carbon dioxide laser beam was scanned across the surface to selectively remove the composite without excessive damage to the underlying sound enamel. The residual composite and the damage to the underlying enamel was evaluated using optical microscopy. Results The laser was able to rapidly remove composite from tooth buccal and occlusal surfaces with minimal damage to the underlying sound enamel and without excessive heat accumulation in the tooth. Conclusion This study demonstrated that composite can be selectively removed from tooth surfaces at clinically relevant rates using a CO2 laser operating at 9.3-μm with high pulse repetition rates with minimal heat deposition and damage to the underlying enamel.

First-generation students’ underperformance at university: the impact of the function of selection
Jury, Mickaël; Smeding, Annique; Darnon, Céline
2015-01-01
According to recent research, university not only has the role to educate and train students, it also has the role to select the best students. We argue that this function of selection disadvantages first-generation students, in comparison with continuing-generation students. Thus, the mere activation of the function of selection should be sufficient to produce achievement differences between first-generation and continuing-generation students in a novel academic task. Furthermore, we propose that when the function of selection is salient, first-generation students would be more vigilant to a cue that may confirm their inferiority, which should explain their underperformance. In the present experiment, participants were asked to complete an arithmetic modular task under two conditions, which either made the function of selection salient or reduced its importance. Participants’ vigilance to a threatening cue (i.e., their performance relative to others) was measured through an eye-tracking technique. The results confirmed that first-generation students performed more poorly compared to continuing-generation students only when the function of selection was salient while no differences appeared in the no-selection condition. Regarding vigilance, the results did not confirm our hypothesis; thus, mediation path could not be tested. However, results indicated that at a high level of initial performance, first-generation students looked more often at the threatening cue. In others words, these students seemed more concerned about whether they were performing more poorly than others compared to their continuing-generation counterparts. Some methodological issues are discussed, notably regarding the measure of vigilance. PMID:26074854

The Integrated Composites ANalyzer (ICAN), a stand-alone computer code, incorporates micromechanics equations and laminate theory to analyze/design multilayered fiber composite structures. Procedures for both the implementation of new data in ICAN and the selection of appropriate measured data are summarized for: (1) composite systems subject to severe thermal environments; (2) woven fabric/cloth composites; and (3) the selection of new composite systems including those made from high strain-to-fracture fibers. The comparisons demonstrate the versatility of ICAN as a reliable method for determining composite properties suitable for preliminary design.

Development and Validation of the Conceptual Assessment of Natural Selection (CANS)
Kalinowski, Steven T.; Leonard, Mary J.; Taper, Mark L.
2016-01-01
We developed and validated the Conceptual Assessment of Natural Selection (CANS), a multiple-choice test designed to assess how well college students understand the central principles of natural selection. The expert panel that reviewed the CANS concluded its questions were relevant to natural selection and generally did a good job sampling the specific concepts they were intended to assess. Student interviews confirmed questions on the CANS provided accurate reflections of how students think about natural selection. And, finally, statistical analysis of student responses using item response theory showed that the CANS did a very good job of estimating how well students understood natural selection. The empirical reliability of the CANS was substantially higher than the Force Concept Inventory, a highly regarded test in physics that has a similar purpose. PMID:27856552

Several medical schools include candidates' extracurricular activities in their selection procedure, with promising results regarding their predictive value for achievement during the clinical years of medical school. This study aims to reveal whether the better achievement in clinical training of students selected on the basis of their extracurricular activities could be explained by persistent participation in extracurricular activities during medical school (msECAs). Lottery-admitted and selected student admission groups were compared on their participation in three types of msECAs: (1) research master, (2) important board positions or (3) additional degree programme. Logistic regression was used to measure the effect of admission group on participation in any msECA, adjusted for pre-university GPA. Two-way ANCOVA was used to examine the inter-relationships between admission group, participation in msECAs and clerkship grade, with pre-university GPA as covariate. Significantly more selected students compared to lottery-admitted students participated in any msECA. Participation in msECAs was associated with a higher pre-university GPA for lottery-admitted students only, whereas participation in msECAs was associated with higher clerkship grades for selected students only. These results suggest that persistent participation in extracurricular activities of selected students favours better clinical achievement, supporting the inclusion of ECAs in the selection procedure. More insight in the rationale behind participation in extracurricular activities during medical school may explain differences found between lottery-admitted and selected students.

Background There are currently no national standards for school lunch period lengths and little is known about the association between the amount of time students have to eat and school food selection and consumption. Objectives To examine plate waste measurements from students in the control arm from the MEALS study (2011-2012 school year) for the association of the amount of time to eat with school meal selection and consumption. Design Prospective study using up to six repeated measures among students over the school year. Participants/Setting 1001 students in grades 3-8 attending 6 participating elementary/middle schools in an urban, low-income school district where lunch period lengths varied from 20-30 minutes. Main Outcome Measures School food selection and consumption were collected using plate waste methodology. Statistical Analyses Performed Logistic regression and mixed-model ANOVA was used to examine food selection and consumption. Results Compared with meal component selection when students had at least 25 minutes to eat, students were significantly less likely to select a fruit (44% vs. 57%; p=0.0001) compared with when students had fewer than 20 minutes to eat. There were no significant differences in entrée, milk, or vegetable selection. Among those who selected a meal component, students with fewer than 20 minutes to eat consumed 13% less of their entrée (p<0.0001), 10% less of their milk (p<0.0001), and 12% less of their vegetable (p=0.0002) compared to when students had at least 25 minutes to eat. Conclusions Over the school year, a substantial number of students had insufficient time to eat, which was associated with significantly decreased entrée, milk, and vegetable consumption compared with students who had more time to eat. School policies that encourage lunches with at least 25 minutes of seated time may reduce food waste and improve dietary intake. PMID:26372337

Background. Previous research suggests that use of BMI as a screening tool to assess health in youth has limitations. Valid alternative measures to assess body composition are needed to accurately identify children who are aerobically fit, which is an indicator of health status. The purpose of this study was to examine the associations between select anthropometric measures and cardiorespiratory fitness test performance in middle-school students. Methods. Participants included 134 students (65 boys and 69 girls) recruited from the 6th, 7th, and 8th grades. Anthropometric measures consisted of BMI, waist circumference (WC), waist-to-height ratio (WHtR), and percent body fat estimated from two-site skinfolds (%BF-SKF), as well as the hand-held OMRON BIA device (%BF-BIA). Cardiorespiratory fitness tests included the one-mile run and PACER test. Data were collected on four separate testing days during the students' physical education classes. Results. There were statistically significant moderate correlations between the %BF estimations, WHtR, and cardiorespiratory fitness test scores in both genders (P < .001). BMI at best only displayed weak correlations with the cardiorespiratory fitness test scores. Conclusions. The results suggest that alternative measures such as %BF-SKF, %BF-BIA, and WHtR may be more valid indicators of youth aerobic fitness lending to their preferred use over BMI. PMID:23533727

Purpose: The authors analyzed the demographics of potential future physiotherapists to determine whether they were representative of the Canadian population. The specific objectives were to examine selected demographic variables from all applicants to and students in Ontario English-language Master of Physical Therapy programmes in admission cycles 2004-2014, inclusive, and to analyze the results as compared with Canadian population data. Method: Anonymized applicant records ( n =14,135) were obtained for admission cycles 2004-2014, inclusive. Variables examined for applicants and students included their gender, geographical location from Canadian and international regions, Aboriginal identity, and immigrant status. A descriptive analysis of counts and proportions was conducted for all variables. Results: The majority of applicants were women (70%), from southern Ontario (73%), and Canadian born (82%). Aboriginal and rural applicants made up small proportions of the applicant pool (1% and 12%, respectively). The number of applicants from British Columbia was proportionally high relative to those from other Canadian provinces. Conclusion: Although Ontario's physiotherapy education programmes remain female dominated, the demographics of applicants and students are otherwise mostly representative of the diverse Canadian population, although very low in the number of Aboriginal peoples. Further research is needed to understand the diversity and composition of the Canadian physiotherapy workforce.

While cross-sectional studies have shown that hookah tobacco smoking (HTS) is an increasingly popular behavior among university students, little is known about factors associated with initiation. This study sought to determine associations between knowledge, attitudes, and normative beliefs and initiation of HTS among university students. Data were from a prospective longitudinal cohort study of 569 randomly selected first- and second-year university students. Online questionnaires that were developed in accordance with our composite theoretical model were completed in September 2010 and April 2011. About one-seventh (13%) of participants initiated HTS by follow-up. Positive attitudes and favorable normative beliefs were associated with increased adjusted odds of initiation (AOR = 4.12, 95% CI = 2.56, 6.59; and AOR = 2.01, 95% CI = 1.35, 2.99, respectively), while negative attitudes were associated with decreased adjusted odds (AOR = 0.62, 95% CI = 0.48, 0.80). Correct knowledge regarding toxicants associated with HTS was not significantly associated with initiation. While positive attitudes and favorable normative beliefs are associated with initiation of HTS in a cohort of never-users, increased knowledge about toxins is not associated with lower initiation. It may be particularly valuable for educational interventions to attempt to alter positive attitudes and normative beliefs related to HTS.

As technology in medical education expands from teaching tool to crucial component of curricular programming, new demands arise to innovate and optimize educational technology. While the expectations of today's digital native students are significant, their experience and unique insights breed new opportunities to involve them as stakeholders in tackling educational technology challenges. The objective of this paper is to present our experience with a novel medical student-led and faculty-supported technology committee that was developed at Vanderbilt University School of Medicine to harness students' valuable input in a comprehensive fashion. Key lessons learned through the initial successes and challenges of implementing our model are also discussed. A committee was established with cooperation of school administration, a faculty advisor with experience launching educational technologies, and a group of students passionate about this domain. Committee membership is sustained through annual selective recruitment of interested students. The committee serves 4 key functions: acting as liaisons between students and administration; advising development of institutional educational technologies; developing, piloting, and assessing new student-led educational technologies; and promoting biomedical and educational informatics within the school community. Participating students develop personally and professionally, contribute to program implementation, and extend the field's understanding by pursuing research initiatives. The institution benefits from rapid improvements to educational technologies that meet students' needs and enhance learning opportunities. Students and the institution also gain from fostering a campus culture of awareness and innovation in informatics and medical education. The committee's success hinges on member composition, school leadership buy-in, active involvement in institutional activities, and support for committee initiatives. Students should have an integral role in advancing medical education technology to improve training for 21st-century physicians. The student technology committee model provides a framework for this integration, can be readily implemented at other institutions, and creates immediate value for students, faculty, information technology staff, and the school community.

Selective logging of tropical forests is increasing in extent and intensity. The duration over which impacts of selective logging persist, however, remains an unresolved question, particularly for African forests. Here, we investigate the extent to which a past selective logging event continues to leave its imprint on different components of an East African forest 45 years later. We inventoried 2358 stems ≥10 cm in diameter in 26 plots (200 m × 10 m) within a 5.2 ha area in Kibale National Park, Uganda, in logged and unlogged forest. In these surveys, we characterized the forest light environment, taxonomic composition, functional trait composition using three traits (wood density, maximum height and maximum diameter) and forest structure based on three measures (stem density, total basal area and total above-ground biomass). In comparison to unlogged forests, selectively logged forest plots in Kibale National Park on average had higher light levels, different structure characterized by lower stem density, lower total basal area and lower above-ground biomass, and a distinct taxonomic composition driven primarily by changes in the relative abundance of species. Conversely, selectively logged forest plots were like unlogged plots in functional composition, having similar community-weighted mean values for wood density, maximum height and maximum diameter. This similarity in functional composition irrespective of logging history may be due to functional recovery of logged forest or background changes in functional attributes of unlogged forest. Despite the passage of 45 years, the legacy of selective logging on the tree community in Kibale National Park is still evident, as indicated by distinct taxonomic and structural composition and reduced carbon storage in logged forest compared with unlogged forest. The effects of selective logging are exerted via influences on tree demography rather than functional trait composition.

OBJECTIVE To study how clinical preceptors select patients for medical student teaching in ambulatory care and to explore key factors they consider in the selection process. DESIGN Qualitative analysis of transcribed interviews. SETTING Harvard Medical School, Boston, Mass. PARTICIPANTS Nineteen physicians (14 general internists and 5 general pediatricians) who serve as clinical preceptors. MEASUREMENTS Responses to in-depth open-ended interview regarding selection of patients for participation in medical student teaching. MAIN RESULTS Preceptors consider the competing needs of the patient, the student, and the practice the most important factors in selecting patients for medical student teaching. Three dominant themes emerged: time and efficiency, educational value, and the influence of teaching on the doctor-patient relationship. These physicians consciously attempt to select patients whose participation in medical student teaching maximizes the efficiency of the clinical practice and optimizes the students' educational experiences, while minimizing any potential for harming the relationship between preceptor and patient. CONCLUSIONS These findings may help validate the frustration preceptors frequently feel in their efforts to teach in the outpatient setting. Becoming more cognizant of the competing interests—the needs of the patient, the student, and the practice—may help physicians to select patients to enhance the educational experience without compromising efficiency or the doctor-patient relationship. For educators, this study suggests an opportunity for faculty development programs to assist the clinical preceptor both in selecting patients for medical student teaching and in finding ways to maximize the efficiency and educational quality of the outpatient teaching environment.

Uncivil behavior by a faculty member or student can threaten a classroom environment and make it less conducive to learning. The aim of this study was to explore faculty behaviors that dental faculty and students perceive to be uncivil when exhibited in the classroom and clinic. In 2015, all faculty, administrators, and students at a single academic dental institution were invited to participate in an electronic survey that used a five-point Likert scale for respondents to indicate their agreement that 33 faculty behaviors were uncivil. Response rates were 49% for faculty and 59% for students. Significant differences were found between student and faculty responses on 22 of the 33 behavioral items. None of the three category composite scores differed significantly for students compared to faculty respondents. The category composite scores were not significantly associated with gender, ethnicity, or age for faculty or students. Overall, this study found significant differences between students and faculty about perceived uncivil faculty behaviors, though not for categories of behaviors.

We probe the effect of seating arrangement, group composition and group-based competition on students' performance in Physics using a teaching technique adopted from Mazur's peer instruction method. Ninety eight lectures, involving 2339 students, were conducted across nine learning institutions from February 2006 to June 2009. All the lectures were interspersed with student interaction opportunities (SIO), in which students work in groups to discuss and answer concept tests. Two individual assessments were administered before and after the SIO. The ratio of the post-assessment score to the pre-assessment score and the Hake factor were calculated to establish the improvement in student performance.more » Using actual assessment results and neural network (NN) modeling, an optimal seating arrangement for a class was determined based on student seating location. The NN model also provided a quantifiable method for sectioning students. Lastly, the study revealed that competition-driven interactions increase within-group cooperation and lead to higher improvement on the students' performance.« less

Selection as a learning experience: an exploratory study
de Visser, Marieke; Laan, Roland F; Engbers, Rik; Cohen-Schotanus, Janke; Fluit, Cornelia
2018-01-01
Introduction Research on selection for medical school does not explore selection as a learning experience, despite growing attention for the learning effects of assessment in general. Insight in the learning effects allows us to take advantage of selection as an inclusive part of medical students’ learning process to become competent professionals. The aims of this study at Radboud University Medical Center, the Netherlands, were 1) to determine whether students have learning experiences in the selection process, and, if so, what experiences; and 2) to understand what students need in order to utilize the learning effects of the selection process at the start of the formal curriculum. Materials and methods We used focus groups to interview 30 students admitted in 2016 about their learning experiences in the selection process. Thematic analysis was used to explore the outcomes of the interviews and to define relevant themes. Results In the selection process, students learned about the curriculum, themselves, their relation to others, and the profession they had been selected to enter, although this was not explicitly perceived as learning. Students needed a connection between selection and the curriculum as well as feedback to be able to really use their learning experiences for their further development. Discussion Medical school selection qualifies as a learning experience, and students as well as medical schools can take advantage of this. We recommend a careful design of the selection procedure, integrating relevant selection learning experiences into the formal curriculum, providing feedback and explicitly approaching the selection and the formal curriculum as interconnected contributors to students’ development.

To compare the school lunch consumption of Texas middle-school students with the 2009 Institute of Medicine's (IOM) school meal report recommendations. These new lunch menu patterns increase fruit to one serving and vegetables to two servings, with 50 % wholegrain food. Lunch food records were collected from middle-school students from four schools in south-east Texas in the spring of 2008, and entered into the Nutrition Data System for Research software. Average intake was calculated for those consuming meals according to the National School Lunch Program (NSLP; n 5414) and for those consuming lunch from other sources (n 239). The percentage of students selecting each food group was calculated. Middle schools in south-east Texas. Middle-school students in south-east Texas. Students consuming NSLP meals reported consuming almost 1/2 serving of fruit, 3/4 serving of vegetables, 8 oz of milk and 1/3 serving of whole grains at lunch. Non-NSLP consumers reported almost no intake of fruit, vegetables or milk, and consumed 1/4 serving of whole grains at lunch. Among NSLP consumers, about 40% selected and consumed a fruit serving. About two-thirds of students selected a vegetable, consuming about 67 %. Less than 4% selected a dark green or orange vegetable. Students' lunch intake did not meet the new IOM recommendations. Few students selected dark green or orange vegetables, and only 40 % selected fruit. Whole grains consumption was low. Interventions with all stakeholders will be necessary to improve students' food and beverage selections overall when school meal patterns are revised.

Improved research ability is a core competency to achieve in health professionals. The Selectives is a three-year, longitudinal, community-based programme within the undergraduate curriculum which aims to develop research capacity in all medical students during the prescribed curriculum. In relation to the programme, the authors describe the types of studies conducted by students, conditions that facilitated their learning, how the experience improved students' knowledge of research and public health and their development of reflective learning practices. A cohort of 212 students completed the Selectives Programme in 2014, and 69 (32 %) completed an anonymous online evaluation thereafter. Data collected include students' perceptions of the research component of Selectives; its impact on their knowledge of research and a documentary analysis of their research protocols and posters. Ethical approval for the ongoing evaluation of the Selectives was sought and obtained from the institutional Biomedical Research Ethics Committee. During Selectives, 75 groups of 2-4 students conducted research studies of primary health care problems in community settings. Each group is assessed on their presentation of research findings as a scientific poster. The Selectives facilitated learning for the majority of the cohort. Students reported positive learning experiences about the research process, including ethics; protocol writing; data processing; dissemination of findings and results; and their use in informing a health promotion intervention. Students reported having gained a better understanding of their strengths and weaknesses through reflective learning from this academic activity. The Selectives is scheduled adjacent to the students' mid-year vacation. This scheduling together with the placement in the students' home community minimizes travel and accommodation costs associated with working outside the academic teaching platform and therefore makes it a cost-effective model in a low resource context. The Selectives has proven beneficial to develop a range of generic and practical research competencies for a full cohort of students enrolled in the undergraduate medical curriculum. The Selectives research process is integrated with learning about population health and the social determinants of health in a primary health care setting.
Process for reproducibly preparing titanium subhydride
Carlson, Richard S.
1982-01-01
Titanium subhydride is produced in a reactor by heating a selected amount of finely divided titanium compound at a selected temperature for a selected period of time under dynamic vacuum conditions. Hydrogen is removed substantially uniformly from each powder grain and there is produced a subhydride of substantially uniform titanium-hydrogen composition. Selection of the amount, temperature and time produces a subhydride of selected titanium-hydrogen composition.

On average, students attending selective schools outperform their non-selective counterparts in national exams. These differences are often attributed to value added by the school, as well as factors schools use to select pupils, including ability, achievement and, in cases where schools charge tuition fees or are located in affluent areas, socioeconomic status. However, the possible role of DNA differences between students of different schools types has not yet been considered. We used a UK-representative sample of 4814 genotyped students to investigate exam performance at age 16 and genetic differences between students in three school types: state-funded, non-selective schools (`non-selective'), state-funded, selective schools (`grammar') and private schools, which are selective (`private'). We created a genome-wide polygenic score (GPS) derived from a genome-wide association study of years of education (EduYears). We found substantial mean genetic differences between students of different school types: students in non-selective schools had lower EduYears GPS compared to those in grammar (d = 0.41) and private schools (d = 0.37). Three times as many students in the top EduYears GPS decile went to a selective school compared to the bottom decile. These results were mirrored in the exam differences between school types. However, once we controlled for factors involved in pupil selection, there were no significant genetic differences between school types, and the variance in exam scores at age 16 explained by school type dropped from 7% to <1%. These results show that genetic and exam differences between school types are primarily due to the heritable characteristics involved in pupil admission.

An undersupply of generalists doctors in rural communities globally led to widening participation (WP) initiatives to increase the proportion of rural origin medical students. In 2002 the Australian Government mandated that 25% of commencing Australian medical students be of rural origin. Meeting this target has largely been achieved through reduced standards of entry for rural relative to urban applicants. This initiative is based on the assumption that rural origin students will succeed during training, and return to practice in rural locations. One aim of this study was to determine the relationships between student geographical origin (rural or urban), selection scores, and future practice intentions of medical students at course entry and course exit. Two multicentre databases containing selection and future practice preferences (location and specialisation) were combined (5862), representing 54% of undergraduate medical students commencing from 2006 to 2013 across nine Australian medical schools. A second aim was to determine course performance of rural origin students selected on lower scores than their urban peers. Selection and course performance data for rural (461) and urban (1431) origin students commencing 2006-2014 from one medical school was used. For Aim 1, a third (33.7%) of rural origin students indicated a preference for future rural practice at course exit, and even fewer (6.7%) urban origin students made this preference. Results from logistic regression analyses showed significant independent predictors were rural origin (OR 4.0), lower Australian Tertiary Admissions Rank (ATAR) (OR 2.1), or lower Undergraduate Medical and Health Sciences Admissions Test Section 3 (non-verbal reasoning) (OR 1.3). Less than a fifth (17.6%) of rural origin students indicated a preference for future generalist practice at course exit. Significant predictors were female gender (OR 1.7) or lower ATAR (OR 1.2), but not rural origin. Fewer (10.5%) urban origin students indicated a preference for generalist practice at course exit. For Aim 2, results of Mann-Whitney U tests confirmed that slightly reducing selection scores does not result in increased failure, or meaningfully impaired performance during training relative to urban origin students. Our multicentre analysis supports success of the rural origin WP pathway to increase rural student participation in medical training. However, our findings confirm that current selection initiatives are insufficient to address the continuing problem of doctor maldistribution in Australia. We argue for further reform to current medical student selection, which remains largely determined by academic meritocracy. Our findings have relevance to the selection of students into health professions globally.

The impact of climate change is often discussed using examples from Polar Regions such as decreasing polar bear populations but significant changes are happening to local climates around the world. Climate change is often perceived as happening elsewhere, evoking a sense that others have to take action to mitigate climate change. Learning about climate change is very tangible for students when it addresses impacts they can observe close to their home. The Lens on Climate Change (LOCC) program engaged Colorado middle and high school students in producing short videos about climate change topics in Colorado, specifically ones that are impacting students' lives and their local community. Participating schools were located in rural, suburban and urban Colorado many of which have diverse student populations and high Free and Reduced Lunch rates. Project staff recruited university graduate and undergraduate student to mentor the students in their research and video production. With the help of these mentors, ten student groups selected and researched climate topics, interviewed science experts from local research institutes and produced short videos. The program aimed at engaging students in self-motivated researching and learning about a climate topic. Furthermore, it served as a way to spark students' interest in a career in science by matching them with college students for the program duration and bringing them to the University of Colorado campus for a final screening event, for many of students their first visit to a college campus. The LOCC middle and high school student groups were in addition paired with undergraduate student groups enrolled in a college course that explores climate change through artistic compositions. The undergraduate students were tasked to develop a companion video based only on a brief prompt from the secondary students. Both student videos were screened back-to-back at a final screening. The LOCC project's goal was to connect secondary students, who would otherwise not have the opportunity, with college life and the scientific community. Our evaluation results showed that the process of video production was a powerful tool for the students to explore and learn about climate change topics. Students and teachers appreciated the unique approach to learning.

To report, and determine reasons for, a change in the gender ratio observed among enrolled medical students after removal of the interview from the selection process. Cross-sectional study of 4051 students admitted to the medical program at the University of Queensland between 2004 and 2012. Students are enrolled either directly as graduates or via a school-leaver pathway. Change in proportions of male and female students over time, and gender-specific scores in the three sections of the GAMSAT (Graduate Medical School Admissions Test). Between 2004 and 2008 (when an interview was part of the selection process), 891 enrolled students (51.4%) were male, whereas between 2009 and 2012 (no interview), 1134 (57.7%; P < 0.001) were male. This change in gender ratio was limited to domestic direct graduate-entry students, and the male proportion in this group rose from 50.9% (705 students) before the interview was removed to 64.0% (514 students; P < 0.001) after removal of the interview (reaching 73.8% in 2012). Between 2004 and 2012, male students consistently performed better than female students on GAMSAT section III (mean score, 71.5 v 68.5; P < 0.001). The proportion of males enrolled in the medical program at this university increased markedly after removal of the interview from the selection process. This change is limited to domestic direct graduate-entry students, and seems to be due to higher scores by male students in section III of the GAMSAT. The interview may play an important role in ensuring gender equity in selection, and medical schools should carefully monitor the consequences of changes to selection policy.

Background As technology in medical education expands from teaching tool to crucial component of curricular programming, new demands arise to innovate and optimize educational technology. While the expectations of today’s digital native students are significant, their experience and unique insights breed new opportunities to involve them as stakeholders in tackling educational technology challenges. Objective The objective of this paper is to present our experience with a novel medical student-led and faculty-supported technology committee that was developed at Vanderbilt University School of Medicine to harness students’ valuable input in a comprehensive fashion. Key lessons learned through the initial successes and challenges of implementing our model are also discussed. Methods A committee was established with cooperation of school administration, a faculty advisor with experience launching educational technologies, and a group of students passionate about this domain. Committee membership is sustained through annual selective recruitment of interested students. Results The committee serves 4 key functions: acting as liaisons between students and administration; advising development of institutional educational technologies; developing, piloting, and assessing new student-led educational technologies; and promoting biomedical and educational informatics within the school community. Participating students develop personally and professionally, contribute to program implementation, and extend the field’s understanding by pursuing research initiatives. The institution benefits from rapid improvements to educational technologies that meet students’ needs and enhance learning opportunities. Students and the institution also gain from fostering a campus culture of awareness and innovation in informatics and medical education. The committee’s success hinges on member composition, school leadership buy-in, active involvement in institutional activities, and support for committee initiatives. Conclusions Students should have an integral role in advancing medical education technology to improve training for 21st-century physicians. The student technology committee model provides a framework for this integration, can be readily implemented at other institutions, and creates immediate value for students, faculty, information technology staff, and the school community.

The use of composite materials to selectively reinforce metallic structures provides a low-cost way to reduce weight and a means of minimizing the risks usually associated with the introduction of new materials. An overview is presented of the NASA Langley Research Center programs to identify the advantages and to develop the potential of the selective reinforcement approach to the use of composites. These programs have shown that selective reinforcement provides excellent strength and stiffness improvements to metallic structures. Significant weight savings can be obtained in a cost effective manner. Flight service programs which have been initiated to validate further the merits of selective reinforcement are described.

Dental clinicians have an expanding range of biomaterial choices for restoring tooth structure. Scientific developments in cariology, advances in dental biomaterials, and patients' esthetic concerns have led to a reduction in amalgam restorations and an increase in composite restorations. The aim of this study was to compare teaching time with students' clinical procedures in amalgam and composite posterior restorations in dental schools across the United States. Academic deans in 60 schools were invited to complete a survey that asked for the amount of instructional time for amalgam and composite posterior restorations and the number of clinical restorations performed by their Classes of 2009, 2010, and 2011. Of these 60, 12 returned surveys with complete data, for a 20% response rate. Responses from these schools showed little change in lecture and preclinical laboratory instruction from 2009 to 2011. There was a slight increase in two-surface restorations for both amalgam and composites; however, the total number of reported composite and amalgam restorations remained the same. Of 204,864 restorations reported, 53% were composite, and 47% were amalgam. There were twice as many multisurface large or complex amalgam restorations as composites. One-surface composite restorations exceeded amalgams. Among the participating schools, there was little to no change between curriculum time and clinical procedures. Findings from this preliminary study reflect a modest increase in two-surface resin-based restorations placed by dental students from 2009 to 2011 and little change in curricular time devoted to teaching amalgam restorations. The total number of posterior composite restorations placed by students in these schools was slightly higher than amalgams.

The purpose of the study was to identify factors that were positively associated with persistence to graduation by students who were admitted to Health-Related Programs leading to the degree associate of applied science at Northeast State Community College. The criterion variable in this study was persistence, which was categorized into two groups the persister group (program completers) and the nonpersister (program noncompleters) group. The predictor variables included gender, ethnic origin, first- (or nonfirst-) generation-student status, age, specific major program of study, number of remedial and/or developmental courses taken, grades in selected courses (human anatomy and physiology I and II, microbiology, probability and statistics, composition I, clinical I, clinical II), and number of mathematics and science credit hours earned prior to program admission. The data for this ex post facto nonexperimental design were located in Northeast State's student records database, Banner Information System. The subjects of the study were students who had been admitted into Health-Related Programs of study at a 2-year public community college between the years of 1999 and 2008. The population size was 761. Health-Related Programs of study included Dental Assisting, Cardiovascular Technology, Emergency Medical Technology -- Paramedic, Medical Laboratory Technology, Nursing, and Surgical Technology. A combination of descriptive and inferential statistics was used in the analysis of the data. Descriptive statistics included measures of central tendency, standard deviations, and percentages, as appropriate. Independent samples t-tests were used to determine if the mean of a variable on one group of subjects was different from the mean of the same variable with a different group of subjects. It was found that gender, ethnic origin, first-generation status, and age were not significantly associated with persistence to graduation. However, findings did reveal a statistically significant difference in persistence rates among the specific Health-Related Programs of study. Academic data including grades in human anatomy and physiology I, probability and statistics, and composition I, suggested a relationship between the course grade and persistence to graduation. Findings also revealed a relationship between the number of math and science courses completed and students' persistence to graduation.

Background: Childhood obesity and hypertension are global problems that are on the rise in India. Improving physical activity is an accepted main line of strategy for overcoming poor body composition, hypertension and reduced cardio respiratory fitness (CRF) all of which are considered as independent risk factors for the development of future cardiovascular complications. Aim: Present study was conducted to evaluate the effect of regular unstructured physical training and athletic level training on anthropometric measures, body composition, blood pressure and cardio respiratory fitness in adolescents. Settings and Design: This is a collaborative study between the Department of physiology, Jawaharlal Institute of Postgraduate Medical Education and Research and Residential school, Jawahar Navodhya Vidyalaya, Puducherry, India. Method and Material: Student volunteers in the age group of 12–17 years were classified into athletes (group 1) and physically active non-athletes (group 2). Parameters measured and calculated were weight, height, body mass index, waist and hip circumference, body fat percentage (BF%), fat free mass (FFM), Systolic (SBP) & Diastolic blood pressure (DBP), Mean arterial pressure (MAP), Rate pressure product (RPP) and Predicted VO2 max. Statistical Analysis used: Mean difference between the groups was analysed using unpaired Student’s t–test. All statistical analysis was carried out for two-tailed significance at the 5 % level using SPSS version 19 (SPSSInc, USA). Results: Anthropometric measures, body composition measures and blood pressure values of both the group students were within the normal limits. There was no significant difference in anthropometric and body composition parameters between the group 1 and group 2 students. DBP, MAP and RPP were significantly lower in group 1 students when compared to group 2 students. VO2 max values were more in group 1 girls as compared to group 2 girls while the values of boys were comparable between the two groups. Conclusion: Regular unstructured physical activity for 60 minutes daily for the duration of one year can help the students to maintain their anthropometric parameters, body composition measures and CRF at par with the athletes of the same age and gender. However, athletic level training further reduces the cardiovascular load of the adolescent students. PMID:24179887

The General Medical Council (United Kingdom) advocates development of non-core curriculum Student Selected Components and their inclusion in all undergraduate medical school curricula. This article describes a rationale for the design, delivery, assessment and evaluation of Student Selected Components in Forensic and Legal Medicine. Reference is made to the available evidence based literature pertinent to the delivery of undergraduate medical education in the subject area. A Student Selected Component represents an opportunity to highlight the importance of the legal aspects of medical practice, to raise the profile of the discipline of Forensic and Legal Medicine amongst undergraduate medical students and to introduce students to the possibility of a future career in the area. The authors refer to their experiences of design, delivery, assessment and evaluation of Student Selected Components in Forensic and Legal Medicine at their respective Universities in the Republic of Ireland (Galway) and in the United Kingdom (Oxford).

Most graduate training programs in the biomedical sciences try to attract qualified candidates from underrepresented racial and ethnic groups; however, some universities have more success than others in enrolling students to whom admission is offered. In order to better understand how students select the school they will attend from those offering admission, we studied the experience of two cohorts of applicants to a doctoral program in the biomedical sciences at Stanford University. Based on interviews with 59 students, we conclude that students use different criteria in deciding the schools to which they will apply than they do in selecting the school they will attend from those offering admission. While we found striking consistency across racial and ethnic groups in the criteria used in selecting schools for application, we found clear differences in the factors affecting the choice of school to attend. Especially for Latino and African American students, the perceived quality of the interpersonal environment and a sense of inclusion were key determinants in selecting the school to attend. In this regard, Latino students found the environment at Stanford more welcoming than African American students did.

This study examined young students' perceptions of gender-appropriate science courses. The sample consisted of 427 students in grades 4, 5, and 6, between the ages of 9 and 13. Students completed the Course Selection Sheet (CSS) to choose courses for themselves and members of the opposite gender. A psychosocial framework was offered to explain the differential course selection patterns between young boys and girls. The study reveals a strong gender effect pointing toward stereotypical perceptions of selected science courses for oneself (p 0.01). When students selected science courses for the opposite gender, the evidence of gender-role stereotypes was even greater (p < 0.000). Course selection profiles imply that a reciprocal relationship exists in the number and kind of courses selected by girls and boys. A detailed analysis suggests that both boys and girls perceive physical science and technology-related courses as appropriate subjects for boys to study and life sciences as appropriate subjects for girls to study. Surprisingly, students' future science course selections resemble current enrollment data of master's and doctoral candidates. The students' perceptions of science are seen years prior to the actual encounter with the science courses listed on the course selection menu. These findings question the auspiciousness of programs designed to ameliorate gender differences in science during junior or senior high school years. Suggestions for school curriculum development and the importance of informal science experiences were examined.

Background : Previous studies have shown associations of physical fitness and cognition in children and in younger and older adults. However, knowledge about associations in high-school adolescents and young adults is sparse. Thus, the aim of this study was to evaluate the association of physical fitness, measured as maximal oxygen uptake ([Formula: see text]), muscle mass, weekly training, and cognitive function in the executive domains of selective attention and inhibitory control, in healthy male high-school students. Methods : Fifty-four males (17.9 ± 0.9 years, 72 ± 11 kg and 182 ± 7 cm) completed a [Formula: see text] test, a body composition test and a visual cognitive task based on the Posner cue paradigm with three types of stimuli with different attentional demands (i.e., stimuli presentation following no cue, valid cue or invalid cue presentations). The task consisted of 336 target stimuli, where 56 (17%) of the target stimuli appeared without a cue (no cue), 224 (67%) appeared in the same rectangle as the cue (valid cue) and 56 (17%) appeared in the rectangle opposite to the cue (invalid cue). Mean reaction time (RT) and corresponding errors was calculated for each stimuli type. Total task duration was 9 min and 20 s In addition, relevant background information was obtained in a questionnaire. Results : Linear mixed model analyses showed that higher [Formula: see text] was associated with faster RT for stimuli following invalid cue (Estimate = -2.69, SE = 1.03, p = 0.011), and for stimuli following valid cue (Estimate = -2.08, SE = 1.03, p = 0.048). There was no association of muscle mass and stimuli ( F = 1.01, p = 0.397) or of weekly training and stimuli ( F = 0.99, p = 0.405). Conclusion : The results suggest that cardiorespiratory fitness is associated with cognitive performance in healthy male high-school students in the executive domains of selective attention.

Fifteen students from Turtle Mountain Community College were selected to participate in activities of the RISE project last summer. Eight students successfully completed project activities and received stipends for their participation. These eight students are (1) Jamie Gable, (2) John Morin, (3) Patrick Belgarde, (4) Jason Laducer, (5) Alex Johnson, (6) Eric Houle, (7) Gary Renault, and (8) Kenny DeCoteau. In the fall of 1998, Jamie Gable and Gary Renault went to North Dakota State University to pursue their undergraduate degrees in mechanical engineering, and John Morin and Alex Johnson joined the University of North Dakota's electrical engineering and industrial technology programs, respectively. Remaining four students will continue to participate in the RISE activities this year and transfer to the universities next year. Seven students who failed to complete the RISE project activities during the current award period are encouraged to participate again this fall. The RISE students were enrolled in a special course called "Introduction to Engineering Materials." The project director, Dr. Kamawat, taught the course on Saturdays and Sundays. Theoretical and mathematical background on engineering materials and careers in various engineering professions were discussed in this course. The students attended guest lectures given by engineers and professors and visited local industries. In addition, the students went to North Dakota State University (NDSU) at Fargo, ND, and the University of Minnesota (UMN) at Minneapolis, MN, to tour their engineering departments. At NDSU, they conducted laboratory tests on various engineering materials, such as concrete, steel, wood, plastics, and carbon composites. The students investigated the mechanical behavior of these materials under various loading conditions, collected data, interpreted data, identified possible errors, determined the mechanical properties, and wrote reports on their findings. The students created posters describing their results on the behavior of engineering material. The posters were displayed in the TMCC's student lounge.

The relationship of sex composition of class and instructor's sex to Physical Self-efficacy has yielded conflicting results in several studies. This study examined the relationship of sex composition of class and instructor's sex to scores on Physical Self-efficacy, Perceived Physical Ability, and Physical Self-presentation Confidence of 80 male students enrolled in one of four sections of a strength training class. Analysis indicated no significant difference on Physical Self-efficacy between male students who were enrolled in all male classes or in coeducational classes; improvements in scores on Physical Self-efficacy were not specific to the sex composition of the class or sex of the instructor and no significant difference on Perceived Physical Ability and Physical Self-presentation Confidence between male students who joined an all male class or a coeducational class. Perceived Physical Ability improved from the pretest to the posttest in all classes; and no improvement in scores for Physical Self-presentation Confidence was found in all classes. In conclusion, the analysis showed sex composition of the class and sex of the instructor were not significantly related to scores for self-efficacy.

Medical educators struggle to find effective ways to assess essential competencies such as communication, professionalism, and teamwork. Portfolio-based assessment provides one method of addressing this problem by allowing faculty reviewers to judge performance, as based on a longitudinal record of student behavior. At the Feinberg School of Medicine, the portfolio system measures behavioral competence using multiple assessments collected over time. This study examines whether a preclerkship portfolio review is a valid method of identifying problematic student behavior affecting later performance in clerkships. The authors divided students into two groups based on a summative preclerkship portfolio review in 2014: students who had concerning behavior in one or more competencies and students progressing satisfactorily. They compared how students in these groups later performed on two clerkship outcomes as of October 2015: final grades in required clerkships, and performance on a clerkship clinical composite score. They used Mann-Whitney tests and multiple linear regression to examine the relationship between portfolio review results and clerkship outcomes. They used USMLE Step 1 to control for knowledge acquisition. Students with concerning behavior preclerkship received significantly lower clerkship grades than students progressing satisfactorily (P = .002). They also scored significantly lower on the clinical composite score (P < .001). Regression analysis indicated concerning behavior was associated with lower clinical composite scores, even after controlling for knowledge acquisition. The results show a preclerkship portfolio review can identify behaviors that impact clerkship performance. A comprehensive portfolio system is a valid way to measure behavioral competencies.

This study examines elementary science content standards curriculum coherence between the People's Republic of China and the United States of America. Three aspects of curriculum coherence are examined in this study: topic inclusion, topic duration, and curriculum structure. Specifically this study centers on the following research questions: (1) What science knowledge is intended for elementary students in each country? (2) How long each topic stays in the curriculum? (3) How these topics sequence and connect with each other? (4) And finally, what is the implication for elementary science curriculum development? Four intended science curriculum frameworks were selected respectively for each country. A technique of General Topic Trace Mapping (GTTM) was applied to generate the composite science content standards out of the selected curriculum for each country. In comparison, the composite USA and Chinese elementary science content standards form a stark contrast: a bunch of broad topics vs. a focus on a set of key topics at each grade; an average of 3.4 year topic duration vs. an average of 1.68 year topic duration; a stress on connections among related ideas vs. a discrete disposition of related ideas; laundry list topic organization vs. hierarchical organization of science topics. In analyzing the interrelationships among these characteristics, this study reached implications for developing coherent science content standards: First, for the overall curriculum, the topic inclusion should reflect the logical and sequential nature of knowledge in science. Second, for each grade level, less, rather than more science topics should be focused. Third, however, it should be clarified that a balance should be made between curriculum breadth and depth by considering student needs, subject matter, and child development. Fourth, the topic duration should not be too long. The lengthy topic duration tends to undermine links among ideas as well as lead to superficial treatment of topics.

Compositing multitemporal remote sensing data sets
Qi, J.; Huete, A.R.; Hood, J.; Kerr, Y.

To eliminate cloud and atmosphere-affected pixels, the compositing of multi temporal remote sensing data sets is done by selecting the maximum vale of the normalized different vegetation index (NDVI) within a compositing period. The NDVI classifier, however, is strongly affected by surface type and anisotropic properties, sensor viewing geometries, and atmospheric conditions. Consequently, the composited, multi temporal, remote sensing data contain substantial noise from these external conditions. Consequently, the composited, multi temporal, remote sensing data contain substantial noise from these external effects. To improve the accuracy of compositing products, two key approaches can be taken: one is to refine the compositing classifier (NDVI) and the other is to improve existing compositing algorithms. In this project, an alternative classifier was developed and an alternative pixel selection criterion was proposed for compositing. The new classifier and the alternative compositing algorithm were applied to an advanced very high resolution radiometer data set of different biome types in the United States. The results were compared with the maximum value compositing and the best index slope extraction algorithms. The new approaches greatly reduced the high frequency noises related to the external factors and repainted more reliable data. The results suggest that the geometric-optical canopy properties of specific biomes may be needed in compositing. Limitations of the new approaches include the dependency of pixel selection on the length of the composite period and data discontinuity.
Some Astronomy 101 Activities Using Internet Resources

Reputable Internet sites provide a wealth of visual, textual, and numerical data for student activities, as well as some fun simulations. Three activities will be described which have been used in Astronomy 101 classes for non-science students. An exercise in model making and problem solving uses the Astronomy Workshop (janus.astro.umd.edu/astro/impact.html) of the University of Maryland. This site provides a quick simulation of an impact with a planet. One can choose the target, the projectile composition (icy, rocky, or iron), the projectile's diameter, and the projectile's speed. The output provides the energy of impact, the earthquake magnitude, the crater's diameter and depth, and the frequency of such impacts. Students run simulations, pool their data, then collaborate to try to figure out the numerical model behind the simulations. They make predictions, test them, and learn that graphing and physical insight are both important tools. Extrasolar planets are now numerous and fascinating. Students use data from Geoff Marcy's group (www.exoplanets.org) to calculate the masses of the planets using a spreadsheet. They discover that the masses of the stars must depend on spectral type. Correlations among parameters are investigated graphically. As a preparation for writing term papers students review and critique selected sites (csam.montclair.edu/ west/ideasresources.html, west/astrolnk.html), discuss them in small groups, then present the "best" sites to the whole class. Teamwork, evaluation, critical thinking, and public speaking skills are emphasized in this class session. The students find these collaborative activities to be exciting, challenging, and enjoyable as well as increasing their science literacy and problem solving skills.

The purpose of this study was to examine the interactive effects that a child's race and the racial composition of a classroom have on a variety of sociometric measures. Sociometric nominations were collected from 872 fifth-grade students (48% male, 48% Black) who were in classrooms that ranged from nearly all Black to nearly all White students. Hierarchical Linear Modeling analyses indicated that the race of the child, the race of the rater, and the classroom race composition each impacted sociometric nominations. Results suggest that schools that are more balanced in the distribution of Black and White students might promote more positive interracial peer relationships. However, opportunities to be highly liked and to be perceived as a leader might be greatest in a school in which the child is in the clear racial majority. © 2013 American Orthopsychiatric Association.

There are currently no national standards for school lunch period length and little is known about the association between the amount of time students have to eat and school food selection and consumption. Our aim was to examine plate-waste measurements from students in the control arm of the Modifying Eating and Lifestyles at School study (2011 to 2012 school year) to determine the association between amount of time to eat and school meal selection and consumption. We used a prospective study design using up to six repeated measures among students during the school year. One thousand and one students in grades 3 to 8 attending six participating elementary and middle schools in an urban, low-income school district where lunch period lengths varied from 20 to 30 minutes were included. School food selection and consumption were collected using plate-waste methodology. Logistic regression and mixed-model analysis of variance was used to examine food selection and consumption. Compared with meal-component selection when students had at least 25 minutes to eat, students were significantly less likely to select a fruit (44% vs 57%; P<0.0001) when they had <20 minutes to eat. There were no significant differences in entrée, milk, or vegetable selections. Among those who selected a meal component, students with <20 minutes to eat consumed 13% less of their entrée (P<0.0001), 10% less of their milk (P<0.0001), and 12% less of their vegetable (P<0.0001) compared with students who had at least 25 minutes to eat. During the school year, a substantial number of students had insufficient time to eat, which was associated with significantly decreased entrée, milk, and vegetable consumption compared with students who had more time to eat. School policies that encourage lunches with at least 25 minutes of seated time might reduce food waste and improve dietary intake. Copyright © 2016 Academy of Nutrition and Dietetics.

Medical student selection and society: Lessons we learned from sociological theories.
Yaghmaei, Minoo; Yazdani, Shahram; Ahmady, Soleiman
2016-01-01
The aim of this study was to show the interaction between the society, applicants and medical schools in terms of medical student selection. In this study, the trends to implement social factors in the selection process were highlighted. These social factors were explored through functionalism and conflict theories, each focusing on different categories of social factors. While functionalist theorists pay attention to diversity in the selection process, conflict theorists highlight the importance of socio-economic class. Although both theories believe in sorting, their different views are reflected in their sorting strategies. Both theories emphasize the importance of the person-society relationship in motivation to enter university. Furthermore, the impacts of social goals on the selection policies are derived from both theories. Theories in the sociology of education offer an approach to student selection that acknowledges and supports complexity, plurality of approaches and innovative means of selection. Medical student selection does not solely focus on the individual assessment and qualification, but it focuses on a social and collective process, which includes all the influences and interactions between the medical schools and the society. Sociological perspective of medical student selection proposes a model that envelops the individual and the society. In this model, the selection methods should meet the criteria of merit at the individual level, while the selection policies should aim at the society goals at the institutional level.

Advances of composite systems and their application have revolutionised the management of posterior teeth affected by caries, facilitating a minimally invasive approach. Previous surveys have indicated that the teaching of posterior composites within dental schools was developing, albeit not keeping pace with clinical evidence and the development of increasingly predictable techniques and materials. Concurrently, surveys of dental practice indicate that dental amalgam still predominates as the 'material of choice' for the restoration of posterior teeth within UK general dental practice. In light of such considerations, the aim of this study was to investigate current teaching of posterior composites in Irish and UK dental schools. An online questionnaire which sought information in relation to the current teaching of posterior composites was developed and distributed to the 17 established Irish and UK dental schools with undergraduate teaching programmes in late 2009. Completed responses were received from all 17 schools (response rate = 100%). All 17 schools taught the placement of occlusal and two-surface occlusoproximal composites in premolar and permanent molar teeth. Two schools did not teach placement of three-surface occlusoproximal composites in either premolars or molars. In their preclinical courses, ten schools taught posterior composites before teaching dental amalgams. Fifty-five percent of posterior restorations placed by dental students were of composite (range = 10-90%) and 44% amalgam (range = 10-90%), indicating an increase of 180% in the numbers of posterior composites placed over the past five years. Diversity was noted in the teaching of clinical techniques and students at different schools are trained with different composites and bonding systems. Some cause for concern was noted in the teaching of certain techniques that were not in keeping with existing best evidence, such as the teaching of transparent matrix bands and light-transmitting wedges for occluso-proximal composites (eight schools) and the teaching of bevels on the cavosurface enamel margins of both the occlusal and proximal box margins (three schools). The teaching of posterior composites in the Irish and UK dental schools has substantially increased over the last five years. Dental students in these schools often gain more experience in the placement of posterior composites than amalgam. However, practice trends indicate that a majority of GDPs continue to place amalgam in preference to composite, thereby suggesting a source of tension as current dental students emerge into the dental workforce over the coming years. There is, as a consequence, a challenge to the dental profession and its funding agencies in the UK to encourage more of a shift towards the minimally interventive use of composite systems in the restoration of posterior teeth, in particular among established practitioners.

Recruiting future neuroscientists: what asking the recruits can teach us.
Willcockson, Irmgard U; Phelps, Cynthia L
2004-12-01
Many different strategies are used to recruit students into scientific research careers, including neuroscience research. These strategies are rarely based on knowledge about students; instead, activities are selected based on their ease of implementation. The goal of the LEARN Project is to encourage high school students into mental health science research using the theme of learning and memory. One intervention the authors developed is five Web-based biographies introducing students to contemporary neuroscientist role models studying learning and memory. To guide the design of this intervention, the authors created a survey to determine where students obtain career information and who and what influences their career selection. In a convenience sample of 124 students, the authors found that almost all students use the Internet for information about careers, in addition to consulting family members and teachers. Students' career selections are influenced most by family members, teachers, and people already in the field. The most important factors students look for in their future career are money, fun, and a good match between current interests and future careers. The data affirm the value of outreach efforts that go beyond students to include a broader audience of parents and teachers who play a critical role in career selection.

A Analysis of Saudi Arabian High School Students' Misconceptions about Physics Concepts.
NASA Astrophysics Data System (ADS)
Al-Rubayea, Abdullah A. M.
This study was conducted to explore Saudi high students' misconceptions in selected physics concepts. It also detected the effects of gender, grade level and location of school on Saudi high school students' misconceptions. In addition, a further analysis of students' misconceptions in each question was investigated and a correlation between students' responses, confidence in answers and sensibleness was conducted. There was an investigation of sources of students' answers in this study. Finally, this study included an analysis of students' selection of reasons only in the instrument. The instrument used to detect the students' misconceptions was a modified form of the Misconception Identification in Science Questionnaire (MISQ). This instrument was developed by Franklin (1992) to detected students' misconceptions in selected physics concepts. This test is a two-tier multiple choice test that examines four areas of physics: Force and motion, heat and temperature, light and color and electricity and magnetism. This study included a sample of 1080 Saudi high school students who were randomly selected from six Saudi educational districts. This study also included both genders, the three grade levels of Saudi high schools, six different educational districts, and a city and a town in each educational district. The sample was equally divided between genders, grade levels, and educational districts. The result of this study revealed that Saudi Arabian high school students hold numerous misconceptions about selected physics concepts. It also showed that tenth grade students were significantly different than the other grades. The result also showed that different misconceptions are held by the students for each concept in the MISQ. A positive correlation between students' responses, confidence in answers and sensibleness in many questions was shown. In addition, it showed that guessing was the most dominant source of misconceptions. The result revealed that gender and grade level had an affect on students' choice of decision on the MISQ items. A positive change in the means of gender and grade levels in the multiple choice test and gender differences in selection of reason may be associated with specific concepts. No significant difference in frequencies of the reasons chosen by the student to justify their answers were found in most of the items (10 items).

The aims of this study were to assess: (a) the chemistry, morphology and bioactivity of bio-active glass (BAG) air-abrasive powder, (b) the effect of three air-abrasion operating parameters: air pressure, powder flow rate (PFR) and the abrasive powder itself, on the selective removal of resin composite and (c) the required "time taken". BAG abrasive particles were characterised using scanning electron microscopy-energy dispersive X-ray spectrometry (SEM-EDX) and Fourier-transform infrared spectroscopy (FTIR). Standardised resin composite restorations created within an enamel analogue block (Macor™) in vitro, were removed using air-abrasion undersimulated clinical conditions. 90 standardised cavities were scanned before and after resin composite removal using laser profilometry and the volume of the resulting 3D images calculated. Multilevel linear model was used to identify the significant factors affecting Macor™ removal. BAG powder removed resin composite more selectively than conventional air-abrasion alumina powder using the same operating parameters (p < 0.001) and the effect of altering the unit's operating parameters was significant (p < 0.001). In conclusion, BAG powder is more efficient than alumina in the selective removal of resin composite particularly under specific operating parameters, and therefore may be recommended clinically as a method of preserving sound enamel structure when repairing and removing defective resin composite restorations.

The computer-intensive project consisted of the analysis and synthesis of existing data on composition of comet Halley dust particles. The main objective was to obtain a complete inventory of sulfur containing compounds in the comet Halley dust by building upon the existing classification of organic and inorganic compounds and applying a variety of statistical techniques for cluster and cross-correlational analyses. A student hired for this project wrote and tested the software to perform cluster analysis. The following tasks were carried out: (1) selecting the data from existing database for the proposed project; (2) finding access to a standard library of statistical routines for cluster analysis; (3) reformatting the data as necessary for input into the library routines; (4) performing cluster analysis and constructing hierarchical cluster trees using three methods to define the proximity of clusters; (5) presenting the output results in different formats to facilitate the interpretation of the obtained cluster trees; (6) selecting groups of data points common for all three trees as stable clusters. We have also considered the chemistry of sulfur in inorganic compounds.

Introduction: While cross-sectional studies have shown that hookah tobacco smoking (HTS) is an increasingly popular behavior among university students, little is known about factors associated with initiation. This study sought to determine associations between knowledge, attitudes, and normative beliefs and initiation of HTS among university students. Methods: Data were from a prospective longitudinal cohort study of 569 randomly selected first- and second-year university students. Online questionnaires that were developed in accordance with our composite theoretical model were completed in September 2010 and April 2011. Results: About one-seventh (13%) of participants initiated HTS by follow-up. Positive attitudes and favorable normative beliefs were associated with increased adjusted odds of initiation (AOR = 4.12, 95% CI = 2.56, 6.59; and AOR = 2.01, 95% CI = 1.35, 2.99, respectively), while negative attitudes were associated with decreased adjusted odds (AOR = 0.62, 95% CI = 0.48, 0.80). Correct knowledge regarding toxicants associated with HTS was not significantly associated with initiation. Conclusions: While positive attitudes and favorable normative beliefs are associated with initiation of HTS in a cohort of never-users, increased knowledge about toxins is not associated with lower initiation. It may be particularly valuable for educational interventions to attempt to alter positive attitudes and normative beliefs related to HTS. PMID:24323574

The purpose of this study was to examine the effects of two incentive conditions (a $10 pre-incentive only vs. a $2 pre-incentive and a $10 promised incentive) on response rates, sample composition, substantive data, and cost-efficiency in a survey of college student substance use and related behaviors. Participants were 3000 randomly-selected college students invited to participate in a survey on substance use. Registrar data on all invitees was used to compare response rates and respondents, and web-based data collection on participants was used to compare substantive findings. Participants randomized to the pre-incentive plus promised incentive condition were more likely to complete the survey and less likely to give partial responses. Subgroup differences by sex, class year, and race were evaluated among complete responders, although only sex differences were significant. Men were more likely to respond in the pre-incentive plus promised incentive condition than the pre-incentive only condition. Substantive data did not differ across incentive structure, although the pre-incentive plus promised incentive condition was more cost-efficient. Survey research on college student populations is warranted to support the most scientifically sound and cost-efficient studies possible. Although substantive data did not differ, altering the incentive structure could yield cost savings with better response rates and more representative samples. Copyright © 2012 Elsevier Ltd.

Environmental literacy of Hispanic, urban, middle school students in Houston, Texas
NASA Astrophysics Data System (ADS)
Meuth, Amber M.
With the global crises facing the planet that bring major implications, (Hart & Nolan, 1999; Hungerford & Simmons, 2003) it is imperative that there be an environmentally literate citizenry who can identify, solve, and prevent environmental issues. Since middle school students are evolving into participating citizens and are developing the ability to think in abstract terms, they are a critical group to study regarding levels of environmental literacy. Additionally, with the increased resource needs and decreased air and water quality in highly populated urban areas, focusing on the environmental literacy of students living and attending school in urban areas is essential. The purpose of this study was to describe the levels of environmental literacy of a group of Hispanic, urban, middle school students in Houston, Texas. Sixth, seventh, and eighth grade students who attend a charter school in Houston, Texas were given, the Middle School Environmental Literacy Survey (MSELS). This survey has been developed to measure components of environmental literacy as related to domains identified critical to environmental literacy (McBeth et al., 2008). The four domains include ecological knowledge, environmental affect, cognitive skills, and behavior. Data collected from the survey was used to determine levels of environmental literacy in the following variables: ecological knowledge, verbal commitment, actual commitment, environmental sensitivity, general environmental feelings, and environmental issue and action skills. Descriptive statistics were calculated and analyzed for each grade level and as an entire sample for each variable in order to generate a profile of the group. Composite scores were calculated in the four domains (ecological knowledge, environmental affect, cognitive skills, and behavior) and were compared to high, moderate, and low levels of environmental literacy set forth by top environmental education researchers (McBeth et al., 2008). Additionally, two secondary analyses were conducted. First, mean scores for each grade level were compared by gender to see if gender plays a role in environmental literacy variables. Second, mean scores in each environmental literacy variable were compared by grade level to investigate if significant differences occur between grade levels. The results indicate that the participants in this sample have high levels of ecological knowledge but convey only moderate feelings towards the environment. The students report that they are willing to engage in more pro-environmental behaviors than they actually report doing. They also display modest abilities to indentify and analyze environmental issues as well as select appropriate action plans. Regarding the domains critical to environmental literacy, the mean scores for this sample fell within the high range for ecological knowledge; scores for affect, cognitive skills, and behavior all fell within the moderate range. For each grade level, the overall environmental literacy composite scores also fell within the moderate range. When compared to students in a national study, generally, in the performance based sections of the MSELS, the 6 th and 8th grade students in this sample scored at or above the students in the national sample while on the self-report sections, the 6th and 8th grade students in this sample generally scored below the students in the national sample. That being said, however, when comparing composite scores for the Affect, Cognitive Skills, and Behavior domains, both sets of students scored within the moderate range. In the Knowledge domain, the students in this sample scored in the high range while the students in the national sample scored in the moderate range. Gender did not appear to play a part in the levels of the environmental literacy variables, while grade level may make a difference for certain variables such as verbal commitment, actual commitment, and environmental sensitivity.

Burst mode composite photography for dynamic physics demonstrations

Lincoln, James
2018-05-01
I am writing this article to raise awareness of burst mode photography as a fun and engaging way for teachers and students to experience physics demonstration activities. In the context of digital photography, "burst mode" means taking multiple photographs per second, and this is a feature that now comes standard on most digital cameras—including the iPhone. Sometimes the images are composited to imply motion from a series of still pictures. By analyzing the time between the photos, students can measure rates of velocity and acceleration of moving objects. Some of these composite photographs have already shown up in the AAPT High School Physics Photo Contest. In this article I discuss some ideas for using burst mode photography in the iPhone and provide a discussion of how to edit these photographs to create a composite image. I also compare the capabilities of the iPhone and GoPro cameras in creating these photographic composites.
[Academic burnout and selection-optimization-compensation strategy in medical students].

2014-12-01
This study was conducted to examine the relationship between academic demand, academic burnout, and the selection-optimization-compensation (SOC) strategy in medical students. A total of 317 students at Yeungnam University, comprising 90 premedical course students, 114 medical course students, and 113 graduate course students, completed a survey that addressed the factors of academic burnout and the selection-optimization-compensation strategy. We analyzed variances of burnout and SOC strategy use by group, and stepwise multiple regression analysis was conducted. There were significant differences in emotional exhaustion and cynicism between groups and year in school. In the SOC strategy, there were no significant differences between groups except for elective selection. The second-year medical and graduate students experienced significantly greater exhaustion (p<0.001), and first-year premedical students experienced significantly higher cynicism (p<0.001). By multiple regression analysis, subfactors of academic burnout and emotional exhaustion were significantly affected by academic demand (p<0.001), and 46% of the variance was explained. Cynicism was significantly affected by elective selection (p<0.05), and inefficacy was significantly influenced by optimization (p<0.001). To improve adaptation, prescriptive strategies and preventive support should be implemented with regard to academic burnout in medical school. Longitudinal and qualitative studies on burnout must be conducted.

Inadequate access to health care, lack of health insurance, and significant health disparities reflect crises in health care affecting all of society. Training U.S. physicians to possess not only clinical expertise but also sufficient leadership skills is essential to solve these problems and to effectively improve health care systems. Few models in the undergraduate medical curriculum exist for teaching students how to combine needed leadership competencies with actual service opportunities.The Advanced Leadership Skills in Community Service (ALSCS) selective developed in response to the shortage of leadership models and leadership training for medical students. The ALSCS selective is designed specifically to increase students' leadership skills, with an emphasis on community service. The selective integrates classroom-based learning, hands-on application of learned skills, and service learning. More than 60 medical students have participated in the selective since inception. Short-term outcomes demonstrate an increase in students' self-efficacy around multiple dimensions of leadership skills (e.g., fundraising, networking, motivating others). Students have also successfully completed more than a dozen leadership and community service projects. The selective offers an innovative model of a leadership-skills-based course that can have a positive impact on leadership skill development among medical school students and that can be incorporated into the medical school curriculum.

The interest in raising levels of achievement in math and science has led to a focus on investigating the factors that shape achievement in these subjects (Lamb & Fullarton, 2002) as well as understanding how these factors operate across countries (Baker, Fabrega, Galindo, & Mishook, 2004). The current study examined the individual student factors and classroom factors on fourth grade science achievement within and across five countries. Guided by the previous school learning models, the elements of students' science learning were categorized as student-level and classroom-level factors. The student-level factors included gender, self-confidence in science, and home resources. The classroom-level factors included teacher characteristics, instructional variables and classroom composition. Results for the United States and four other countries, Singapore, Japan, Australia, and Scotland were reported. Multilevel effects of student and classroom variables were examined through Hierarchical Linear Modeling (HLM) using the Trends in International Mathematics and Science Study (TIMSS) 2003 fourth grade dataset. The outcome variable was the TIMSS 2003 science score. Overall, the results of this study showed that selected student background characteristics were consistently related to elementary science achievement in countries investigated. At the student-level, higher levels of home resources and self-confidence and at the classroom-level, higher levels of class mean home resources yielded higher science scores on the TIMSS 2003. In general, teacher and instructional variables were minimally related to science achievement. There was evidence of positive effects of teacher support in the U.S. and Singapore. The emphasis on science inquiry was positively related to science achievement in Singapore and negatively related in the U.S. and Australia. Experimental studies that investigate the impacts of teacher and instructional factors on elementary science achievement are needed. For all the countries investigated, with the exception of Singapore, the between-class variance was much smaller than the within-class variance. Japan had the smallest variation in science achievement among classrooms which indicates the homogeneity across classrooms in Japan. Increasing awareness and knowledge of gender neutral instructional techniques, providing a non-threatening, rich and supportive environment for both genders in classrooms by elementary teachers are to be encouraged. To improve students' self beliefs about science, it is recommended that teachers model science activities and accommodate students' needs and abilities (Bandura, 1997; Britner & Pajares, 2006). Schools and teachers are recommended to develop a successful home-school partnership for improved student learning and positive attitudes toward science (Eccles & Harold, 1996; Epstein & Salinas, 2004). Furthermore, developing a knowledge base for teachers regarding the influences of classroom and school composition is highlighted (Honig, Kahne, & McLaughlin, 2001; Murrel, 2001). At the classroom- and school-level, policy efforts could focus on the distribution of educational resources (Condron & Roscigno, 2003; Goesling, 2003) to compensate for poor family background.

With the amendment of the medical licensure act (Approbationsordnung) in 2012, a four-week clerkship in primary care (FHV) became mandatory. We investigated the expectations with which students begin the FHV, which criteria are relevant in selecting the location for the FHV, and the experiences the students had during the FHV. In a cross-sectional study, all third-year students at both medical schools in Saxony-Anhalt were surveyed in 2013 about their expectations and experiences regarding the FHV. This is the last cohort for which the FHV is optional. Questions were asked about 29 items addressing six topics (personal information, selection of FHV location, selection of FHV medical practice, expectations, experiences, and specialty selection). Out of a student body of 446, responses were received from N=424 (response rate 95.1%; of which 61.8% female). Of these students, 71 (16.7%) had completed the FHV and 70 (16.5%) were planning to; another 267 students (63%) had not (yet) planned to participate in an FHV. Where a student's parents lived, personal recommendations of a particular medical practice and the attractiveness of the region were the most important criteria for selecting the clerkship site. After completing the FHV, the learning objectives reflected themselves in the experiences of the students in a similar order and significance as in the expectations of students who planned or had not (as of yet) planned to complete the FHV. A relevant influence of the FHV confirming the choice to specialize in general practice or outpatient care was not indicated by those who had completed the FHV. After location and practice, the FHV is selected according to personal criteria and in connection with prioritized learning objectives. From the students' perspective, the most frequently named learning objectives are also identified as acquired experience after completing the FHV. However, the FHV does not have a reinforcing effect on the selection of general practice as a specialty.
Study of Selected Composites Copper Concentrate-Plastic Waste Using Thermal Analysis
NASA Astrophysics Data System (ADS)
Szyszka, Danuta
2017-12-01
The paper presents thermal analysis of selected composites (copper concentrate, plastic waste) in two stages. The first stage consisted in thermogravimetric analysis and differential thermal analysis on the applied plastic waste and copper concentrate, and subsequently, a comparative study has been carried out on products obtained, constituting composites of those materials. As a result of analyses, it was found that up to ca. 400 °C composites show high thermal stability, whereas above that temperature, a thermal decomposition of the composite occurs, resulting in emissions of organic compounds, i.e. hydrocarbon compounds and organic oxygenate derivatives.

Young people who study physical education are a priori regarded as having proper body structure and body composition. This assumption cannot be confirmed in the subject literature. To determine the basic auxological parameters in youth who study physical education. 235 first-year students studying physical education were examined: 32% women (n=74) and 68% men (n=161). The students' body height, weight, waist, and hip circumference were measured. Body composition (bioimpedance method), specifying the body fat percentage (FM%) and fat free mass (FFM%) was also assessed. The mean normalized height of the female body was 0.48±1.07 SDS, and for the male body 0.51±1.04 SDS. The mean normalized weight for women was 0.4±0.94 SDS, and for men it was 0.83±0.9 SDS. The mean fat percentage in the body composition of women and men was, respectively, 21.5±5.06, ranging from 10.16% to 35.06%, and 12.5±3.97, ranging from 4.36% to 22.28%. In one-third of the women, the percentage of fat in the body composition was higher than 25%. 1. Young people who choose to study physical education and physical culture are characterized by greater height and greater body weight than the general population, regardless of gender. 2. Short persons study physical education less often than tall individuals. 3. The greater body weight observed in the majority of students studying physical education, in comparison to that of the general population, was caused by a dominant percentage of lean body mass in body composition; unexpectedly, however, some women were observed to have relatively high fat content. 4. Use of the body mass index and waist-hip ratio was not a sufficiently sensitive screening examination to detect fatness in physically active young adults; therefore, it should not substitute for the determination of fat content in body composition.

This study was designed to identify reasons underrepresented minority (URM) dental students select a dental school and to determine the factors that contribute to their resolve to complete their programs. A survey questionnaire developed from interviews with URM students was sent to Minority/Admissions Officers or deans of dental schools that enrolled URM students for distribution to their minority students. A total of 198 questionnaires were received from minority students in all levels of dental school. The results were that 74 percent said they selected a school for its reputation, and 49.5 percent chose a dental school even if the financial aid package was less than what was offered in other schools. African American, Hispanic, and Native American students prefer integrated interview days with nonminority applicants and disapprove of "special" days designated for URMs. The presence of other minority students was not an important factor in the selection of a school but is an important source of support while attending dental school. Dental school minority alumni also play a significant role in the selection of a school. Results of the study can be useful in planning recruitment and retention programs.

To address the question can the fatty acid selectivity of plant lipases be predicted from the composition of the seed triglyceride, we have characterised the selectivity of lipases from a wide range of oilseeds with diverse fatty acid compositions. For this study, a novel hydrolysis assay using a fully randomised oil, was developed. From some seed sources (e.g. Cinnamomum camphora), lipases show high preference for particular fatty acids, whilst from others (e.g. Brassica napus, Theobroma cacao80% saturated or 'unusual' fatty acids may contain lipases which exhibit selectivity. It therefore follows that since the majority of seeds are composed of unsaturated fatty acids, that highly selective lipases will be unusual in nature. However lipases from some species of the Cuphea genera show exceptionally high preference for particular fatty acids. For example, lipase from seeds of Cuphea procumbans has over 20-fold selectivity for C10:0.

Atomic force microscopy imaging combined with selective chemical etching is employed to quantitatively investigate three-dimensional (3D) composition distributions of single GeSi quantum rings (QRs). In addition, the 3D quantitative composition distributions and the corresponding conductance distributions are simultaneously obtained on the same single GeSi QRs by conductive atomic force microscopy combined with selective chemical etching, allowing us to investigate the correlations between the conductance and composition distributions of single QRs. The results show that the QRs' central holes have higher Ge content, but exhibit lower conductance, indicating that the QRs' conductance distribution is not consistent with their composition distribution. By comparing the topography, composition and conductance profiles of the same single QRs before and after different etching processes, it is found that the conductance distributions of GeSi QRs do not vary with the change of composition distribution. Instead, the QRs' conductance distributions are found to be consistent with their topographic shapes, which can be supposed to be due to the shape determined electronic structures.

Andaç, Müge; Baydemir, Gözde; Yavuz, Handan; Denizli, Adil
2012-11-01
A new composite protein-imprinted macroporous cryogel was prepared for depletion of albumin from human serum prior to use in proteom applications. Polyhydroxyethyl-methacylate-based molecularly imprinted polymer (MIP) composite cryogel was prepared with high gel fraction yields up to 83%, and its morphology and porosity were characterized by Fourier transform infrared, scanning electron microscopy, swelling studies, flow dynamics, and surface area measurements. Selective binding experiments were performed in the presence of competitive proteins human transferrin (HTR) and myoglobin (MYB). MIP composite cryogel exhibited a high binding capacity and selectivity for human serum albumin (HSA) in the presence of HTR and MYB. The competitive adsorption amount for HSA in MIP composite cryogel is 722.1 mg/dL in the presence of competitive proteins (HTR and MYB). MIP composite cryogel column was successfully applied in the fast protein liquid chromatography system for selective depletion of albumin in human serum. The depletion ratio was highly increased by embedding beads into cryogel (85%). Finally, MIP composite cryogel can be reused many times with no apparent decrease in HSA adsorption capacity.

Several years ago I had to select a new textbook for my calculus-based introductory physics class. I subscribe to Just-in-Time Teaching methods, which require students to read the book before the material is covered in class. Thus, the readability of the text by the students is critical. However, I did not feel that I was the best judge of this factor, so I turned the textbook selection into a class project. The students unanimously chose one textbook, which I have now successfully used for three years. The project was decidedly worthwhile, and I gained considerable insight into what students prefer in a textbook.

Herein, we report a highly selective dopamine electrochemical sensor based on electrochemically pretreated graphite/nafion composite modified screen printed carbon (SPC) electrode. Electrochemically activated graphite/nafion composite was prepared by using a simple electrochemical method. Scanning electron microscope (SEM) used to characterize the surface morphology of the fabricated composite electrode. The SEM result clearly indicates that the graphitic basal planes were totally disturbed and leads to the formation of graphite nanosheets. The composite modified electrode showed an enhanced electrocatalytic activity toward the oxidation of DA when compared with either electrochemical pretreated graphite or nafion SPC electrodes. The fabricated composite electrode exhibits a good electrocatalytic oxidation toward DA in the linear response range from 0.5 to 70 μM with the detection limit of 0.023 μM. The proposed sensor also exhibits very good selectivity and stability, with the appreciable sensitivity. In addition, the proposed sensor showed satisfactory recovery results toward the commercial pharmaceutical DA samples. Copyright © 2013 Elsevier Inc. All rights reserved.

Evaluation of selection criteria for graduate students in radiation therapy.
Schneider-Kolsky, Michal; Wright, Caroline; Baird, Marilyn
2006-12-01
Selection of suitable students into graduate medical and specialist health professional courses can be difficult. Historically, selection of students was primarily based on prior academic performance. Recently, however, more emphasis has been placed on considering broader academic backgrounds and personal characteristics and attitudes of students, but no reliable measurement tool is available to predict student success and satisfaction with their choice of profession. The aim of this study was to survey practising radiation therapists in Australia to seek their opinions regarding suitable selection criteria for graduate entry radiation therapy (RT) students in order to optimize selection procedures for future applicants. Four hundred questionnaires were sent to nine RT centres in three states within Australia. All nine clinics participated in the survey and 189 questionnaires were returned. Results show that the majority of radiation therapists place a high level of importance upon a sound knowledge of physics and mathematics, as well as life experience, and agree that a visit to an RT clinic plus an interview comprise important components of the selection process. Humanities, psychology and a psychometric test were not viewed as essential entry requirements. Experienced radiation therapists placed less value on academic performance in the primary degree and were more likely to include an interview as a selection criterion than junior practitioners. Empathy for patients was identified as the most important personal attribute. It is thus recommended that not only cognitive but also personal skills be evaluated during the selection of prospective radiation therapists.

In Israel, there is a shortage of family medicine (FM) specialists that is occasioned by a shortage of students pursuing a FM career. A questionnaire, based on methods adapted from marketing research, was used to provide insight into the medical specialty selection process. It was distributed to 6 th -year medical students from two Israeli medical schools. A response rate of 66% resulted in collecting 218 completed questionnaires. Nineteen of the students reported that they were interested in FM, 68% of them were women. When compared to students not interested in FM, the selection criteria of students interested in FM reflected greater interest in a bedside specialty which provides direct long-term patient care. These latter students were also more interested in a controllable lifestyle that allowed time to be with family and children and working outside the hospital especially during the daytime. These selection criteria aligned with their perceptions of FM, which they perceived as providing them with a controllable lifestyle, allowing them to work limited hours with time for family and having a reasonable income to lifestyle ratio. The students not interested in FM, agreed with those interested in FM, that the specialty affords a controllable lifestyle and the ability to work limited hours Yet, students not interested in FM more often perceived FM as being a boring specialty and less often perceived it as providing a reasonable income to lifestyle ratio. Additionally, students not interested in FM rated the selection criteria, academic opportunities and a prestigious specialty, more highly than did students interested in FM. However, they perceived FM as neither being prestigious nor as affording academic opportunities CONCLUSION: This study enriches our understanding of the younger generation's attitudes towards FM and thus provides administrators, department chairs and residency program directors with objective information regarding selection criteria and the students' perceptions of FM. We identified the disconnect between the selection criteria profiles and the perceptions of FM of students not inclined to pursue a residency in FM. This allowed for recommendations on how to possibly make FM more attractive to some of these students.

Cavity Adaptation of Water-Based Restoratives Placed as Liners under a Resin Composite
Gaintantzopoulou, Maria D.; Eliades, George
2017-01-01
Purpose. To investigate the cavity adaptation of mineral trioxide (ProRoot MTA/MT), tricalcium silicate (Biodentine/BD), and glass ionomer (Equia Fil/EF) cements used as liners and the interfacial integrity between those liners and a composite resin placed as the main restorative material. Materials and Methods. Standardized class I cavities (n: 8 per group) were prepared in upper premolars. Cavities were lined with a 1 mm thick layer of each of the tested materials and restored with Optibond FL adhesive and Herculite Precis composite resin. Cavity adaptation of the restorations was investigated by computerized X-ray microtomography. The regions of interest (ROI) were set at the cavity-liner (CL) interface and the liner-resin (LR) interface. The percentage void volume fraction (%VVF) in the ROI was calculated. The specimens were then sectioned and the interfaces were evaluated by reflection optical microscopy, to measure the % length (%LD) of the interfacial gaps. Selected samples were further evaluated by scanning electron microscopy. Statistical analysis was performed by two-way ANOVA and Student-Newman-Keuls multiple comparison test (a = 0.05). Results. MT showed significantly higher %VVF and %LD values in CL interfaces than BD and EF (p < 0.05). No significant differences were found among the materials for the same values at the LR interfaces. Conclusions. When used as a composite liner, ProRoot MTA showed inferior cavity adaptation at dentin/liner interface when compared to Biodentine and Equia Fil. PMID:28465685

The working groups consisted of 110 participants: untrained students, athletes and dialysed patients; 50.9% women and 49.1% men; with an average age of 26.03. The BMI of the patients is significantly higher than the BMI of the athletes and untrained students. No significant differences were found between groups in terms of self-perception of weight. Compared to the physically untrained students and patients, the athletes have a significantly higher level of muscle tissue. The athletes also have a significantly lower adipose tissue than that of the physically untrained students and patients.

The empennage component selected for this program is the vertical fin box of the L-1011 aircraft. The box structure extends from the fuselage production joint to the tip rib and includes the front and rear spars. Various design options were evaluated to arrive at a configuration which would offer the highest potential for satisfying program objectives. The preferred configuration selected consists of a hat-stiffened cover with molded integrally stiffened spars, aluminum trussed composite ribs, and composite miniwich web ribs with integrally molded caps. Material screening tests were performed to select an advanced composite material system for the Advanced Composite Vertical Fin (ACFV) that would meet the program requirements from the standpoint of quality, reproducibility, and cost. Preliminary weight and cost analysis were made, targets established, and tracking plans developed. These include FAA certification, ancillary test program, quality control, and structural integrity control plans.

Polymer membranes were prepared by blending high density polyethylene (HDPE) with ethylene propylene diene terpolymer rubber (EPDM). These blend membranes were evaluated for the selective separation of n-hexane from acetone. The flux and selectivity of the membranes were determined both as a function of the blend composition and feed mixture composition. Results showed that polymer blending method could be very useful to develop new membranes with improved selectivity. Pervaporation properties could be optimized by adjusting the blend composition. The effects of blend ratio, feed composition, and penetrant size on the pervaporation process were analyzed. The permeation properties have been explained on the basis of interaction between the membrane and solvents and blend morphology. Flux increases with increasing alkane content in the feed composition. Copyright © 2011 Elsevier B.V. All rights reserved.

The objectives of this study were to determine the extent to which selection for decreased residual feed intake (RFI) affects pork composition and quality. Pigs from the fifth generation of selection for decreased RFI (select) and a randomly selected line (control) were utilized. Two experiments were conducted. In Exp. 1, barrows (22.6 ± 3.9 kg) from select and control lines were paired based on age and BW. The test was conducted in 8 replicates of pairs for the test period of 6 wk. Calpastatin activity and myosin isoforms profile were determined on samples from the LM. Control barrows were heavier (59.1 vs. 55.0 kg; P < 0.01) at the end of the test period. Calpastatin activity was greater (P < 0.01) in LM of select barrows than control barrows. In Exp. 2, composition and quality of gilts (114 kg) from control and select lines were determined. The model included fixed effects of line, slaughter date, melanocortin-4 receptor (MC4R) genotype, barn group, line × slaughter date, genotype × line interactions, a covariate of off-test BW, and sire, pen, and litter fitted as random effects. The select line (n = 80) had 0.043 kg less (P < 0.05) RFI per day than the control line (n = 89). Loin quality and composition were determined at 2 d postmortem. Desmin degradation was measured at 2 and 7 d postmortem. Purge, cook loss, sensory traits, and star probe texture were measured at 7 to 10 d postmortem on cooked chops. Residual correlations between RFI and composition and quality traits were calculated. Compared with the control line, carcasses from the select line tended to have less (P = 0.09) backfat, greater (P < 0.05) loin depth, and greater (P < 0.05) fat free lean. Loin chops from the select line had less (P < 0.01) intramuscular lipid content than loin chops from control line. Significant residual correlations between RFI and both tenderness (r = 0.24, P < 0.01) and star probe (r = -0.26, P < 0.01) were identified. Selection for decreased RFI has the potential to improve carcass composition with few effects on pH and water-holding capacity. However, decreased RFI could negatively affect tenderness and texture because of decreased lipid content and decreased postmortem protein degradation.

The aim was to examine main reasons for students' medical school choice and their relationship with students' characteristics and motivation during the students' medical study. In this multisite cross-sectional study, all Year-1 and Year-4 students who had participated in a selection procedure in one of the three Dutch medical schools included in the study were invited to complete an online survey comprising personal data, their main reason for medical school choice and standard, validated questionnaires to measure their strength of motivation (Strength of Motivation for Medical School-Revised) and autonomous and controlled type of motivation (Academic Self-regulation Questionnaire). Four hundred seventy-eight students participated. We performed frequency analyses on the reasons for medical school choice and regression analyses and ANCOVAs to study their associations with students' characteristics and motivation during their medical study. Students indicated 'city' (Year-1: 24.7%, n=75 and Year-4: 36.0%, n=52) and 'selection procedure' (Year-1: 56.9%, n=173 and Year-4: 46.9%, n=68) as the main reasons for their medical school choice. The main reasons were associated with gender, age, being a first-generation university student, ethnic background and medical school, and no significant associations were found between the main reasons and the strength and type of motivation during the students' medical study. Most students had based their medical school choice on the selection procedure. If medical schools desire to achieve a good student-curriculum fit and attract a diverse student population aligning the selection procedure with the curriculum and taking into account various students' different approaches is important.

Increasingly positive attitudes have been reported among young people in China towards mental illness, but little is known about Chinese medical students' attitudes towards psychiatry, psychiatric services and patients. We administered a bilingual survey to Wuhan University medical students in the final years of their clinical training. Primary outcomes were composite scores on a 21-item attitudes toward psychiatry (ATP) survey and the number of correct responses to diagnostic questions following a series of three clinical case vignettes. Mean composite score on the ATP items was 78/105 (SD = 9.6), representing overall positive attitudes among the students. Female gender and having learned about more psychiatric disorders were positively associated with a higher mean ATP score and remained so after adjustment for relevant covariates. Chinese medical students reported positive attitudes towards psychiatry, openness with regard to psychiatric services, and respect for psychiatric patients. Learning about a broad spectrum of psychiatric diagnoses and greater clinical contact with patients may improve overall attitudes of Chinese medical students towards psychiatry and their ability to make accurate diagnoses.

Adams, Jeffrey P.; Brissenden, Gina; Lindell, Rebecca S.; Slater, Timothy F.; Wallace, Joy
In an effort to determine how our students were responding to the use of collaborative learning groups in our large enrollment introductory astronomy (ASTRO 101) courses, we systematically observed the behavior of 270 undergraduate students working in 48 self-formed groups. Their observed behaviors were classified as: (i) actively engaged; (ii) watching actively; (iii) watching passively; and (iv) disengaged. We found that male behavior is consistent regardless of the sex-composition of the groups. However, females were categorized as watching passively and or disengaged significantly more frequently when working in groups that contained uneven numbers of males and females. This case study observation suggests that faculty who use collaborative learning groups might find that the level of student participation in collaborative group learning activities can depend on the sex-composition of the group.

Herein we have identified an optimal catalyst, Pd1Ag1.7, for the tandem reductive amination between nitroarenes and aldehydes (selectivity > 93%). Key to the success is the ability to control the compositions of the investigational Pd1-xAgx (x = 0-1) catalysts, as well as the clear composition dependent activity/selectivity trend observed in this study. This catalyst features a wide substrate scope, excellent recyclability, activity and selectivity under ambient conditions.

Students' perceptions of the Undergraduate Medicine and Health Sciences Admissions Test (UMAT).
Dhar, Divya; Perry, William R G; Poole, Phillippa
2012-09-07
Medical schools are still evaluating the place of general cognitive tests in medical student selection. This study explored medical student perceptions of UMAT, and how they prepared for taking the test. Medical students at The University of Auckland and University of Otago in New Zealand were invited to complete a mixed-modality survey. Students had reservations, with 56% reporting UMAT is not an important test for medical students' selection and 67% that it is not a fair test. Eighty-one percent believe it is a stressful or very stressful test. The degree of importance or stress related to the weighting of UMAT in selection decisions. More than half of students spent more than $100 on books and $400 on courses to prepare for UMAT, in addition to the costs of sitting the test. At present, the majority of medical students in New Zealand who responded to the survey do not see UMAT as an acceptable test of non-cognitive attributes. It is costly to students and also stressful.

Students' perceived experience of university admission based on tests and interviews.
Röding, K; Nordenram, G
2005-11-01
The aim of the study was to generate an impression, from the perspective of graduating dental students, of the individualised admissions procedures, which they had undergone 5 years before. The subjects comprised 10 randomly selected students, five male and five female, from two different admission rounds. Qualitative research was used and data were collected by means of semi-structured interviews. The results show that even 5 years later, the students remember clearly the different steps in the selection procedure and they found the procedure relevant. In particular, the admission interviews made a lasting impression. The students consider that being interviewed by one admissions committee member at a time reduces the applicant's apprehension and allows a more personal interview. Several believe that the admissions procedure influences academic achievement or improves self-confidence: implicit in their selection by a committee of experienced professionals is affirmation that they have the potential to become good dentists. The students therefore feel encouraged to aspire to higher achievement. All students believe that motivation is an important non-cognitive attribute for success and that students selected through this mode are not only highly motivated but also well informed, with realistic expectations of the undergraduate programme and their future professional career.

Voluntary exercise and its effects on body composition depend on genetic selection history.
Nehrenberg, Derrick L; Hua, Kunjie; Estrada-Smith, Daria; Garland, Theodore; Pomp, Daniel
2009-07-01
Little is known about how genetic variation affects the capacity for exercise to change body composition. We examined the extent to which voluntary exercise alters body composition in several lines of selectively bred mice compared to controls. Lines studied included high runner (HR) (selected for high wheel running), M16 (selected for rapid weight gain), Institute of Cancer Research (ICR) (randomly bred as control for M16), M16i (an inbred line derived from M16), HE (selected for high percentage of body fat while holding body weight constant), LF (selected for low percentage of body fat), C57BL/6J (common inbred line), and the F1 between HR and C57BL/6J. Body weight and body fat were recorded before and after 6 days of free access to running wheels in males and females that were individually caged. Total food intake was measured during this 6-day period. All pre- and postexercise measures showed significant strain effects. While HR mice predictably exercised at higher levels, all other selection lines had decreased levels of wheel running relative to ICR. The HR x B6 F1 ran at similar levels to HR demonstrating complete dominance for voluntary exercise. Also, all strains lost body fat after exercise, but the relationships between exercise and changes in percent body were not uniform across genotypes. These results indicate that there is significant genetic variation for voluntary exercise and its effects on body composition. It is important to carefully consider genetic background and/or selection history when using mice to model effects of exercise on body composition, and perhaps, other complex traits as well.
School Choice and Educational Inequality in South Korea
Byun, Soo-yong; Kim, Kyung-keun; Park, Hyunjoon
2014-01-01
This study examined the choice debate in South Korea, which centers on the residentially based school assignment policy called the High School Equalization Policy (HSEP). Using a nationally representative sample of South Korean 11th graders, the study further explored the role of the HSEP in educational equality by investigating how HSEP implementation was related to the separation of low and high socioeconomic status (SES) students between schools and how the socioeconomic composition of a school was related to student achievement. Results showed that the odds that low SES students were separated into low SES schools was smaller in the regions of HSEP implementation, where students were randomly assigned to a school based on place of residence, than in the regions of non-HSEP implementation, where students were allowed to choose a school. Results also showed that student achievement significantly depended on the socioeconomic composition of a school students attended in the regions of non-HSEP implementation, whereas this was not the case in the regions of HSEP implementation. We discussed the implications of these findings for the potential impact of school choice policies on educational inequality. PMID:24834021
An Effective Model for Improving Global Health Nursing Competence.
Kang, Sun-Joo
2016-01-01
This paper proposed an effective model for improving global health nursing competence among undergraduate students. A descriptive case study was conducted by evaluation of four implemented programs by the author. All programs were conducted with students majoring in nursing and healthcare, where the researcher was a program director, professor, or facilitator. These programs were analyzed in terms of students' needs assessment, program design, and implementation and evaluation factors. The concept and composition of global nursing competence, identified within previous studies, were deemed appropriate in all of our programs. Program composition varied from curricular to extracurricular domains. During the implementation phase, some of the programs included non-Korean students to improve cultural diversity and overcome language barriers. Qualitative and quantitative surveys were conducted to assess program efficacy. Data triangulation from students' reflective journals was examined. Additionally, students' awareness regarding changes within global health nursing, improved critical thinking, cultural understanding, and global leadership skills were investigated pre- and post-program implementation. The importance of identifying students' needs regarding global nursing competence when developing appropriate curricula is discussed.

It is desirable to develop high-performance composite membranes for efficient CO2 separation in CO2 capture process. Introduction of a highly permeable polydimethylsiloxane (PDMS) intermediate layer between a selective layer and a porous support has been considered as a simple but efficient way to enhance gas permeance while maintaining high gas selectivity, because the introduced intermediate layer could benefit the formation of an ultrathin defect-free selective layer owing to the circumvention of pore penetration phenomenon. However, the selection of selective layer materials is unfavorably restricted because of the low surface energy of PDMS. Various highly hydrophilic membrane materials such as amino group-rich polyvinylamine (PVAm), a representative facilitated transport membrane material for CO2 separation, could not be facilely coated over the surface of the hydrophobic PDMS intermediate layer uniformly. Inspired by the hydrophilic nature and strong adhesive ability of polydopamine (PDA), PDA was therefore selected as a versatile molecular bridge between hydrophobic PDMS and hydrophilic PVAm. The PDA coating endows a highly compatible interface between both components with a large surface energy difference via multiple-site cooperative interactions. The resulting multilayer composite membrane with a thin facilitated transport PVAm selective layer exhibits a notably enhanced CO2 permeance (1887 GPU) combined with a slightly improved CO2/N2 selectivity (83), as well as superior structural stability. Similarly, the multilayer composite membrane with a hydrophilic CO2-philic Pebax 1657 selective layer was also developed for enhanced CO2 separation performance.

In this study, the theory-based model of Ajzen and Fishbein was used to identify factors that influence physical therapist and registered nurse (RN) students' intentions toward working with elderly individuals. A follow-up identified actual job selection. Accredited physical therapist and RN education programs in the Northwest and California were surveyed. Two hundred one students responded; 176 survey questionnaires were usable. A survey instrument was developed based on Ajzen and Fishbein's theory-based model to assess student intention to work with elderly individuals and factors influencing this intention. Graduates were later contacted to determine whether job selection matched intention. For all students, factors influencing intention were student attitudes and student perceptions regarding their families' expectations about the student working with elderly persons. Intention had a positive correlation with job selection. Important underlying beliefs influencing student attitudes, which could be emphasized in academia, include the advantages of getting to know elderly patients and their families and having pleasant patients to work with. Faculty are encouraged to positively reinforce these beliefs throughout the curricula. Results of this study support using a theory-based model to identify predictors of job selection among physical therapist and RN graduates.

Levels of problem behavior were assessed when 4 students with severe disabilities received instruction on preferred versus nonpreferred tasks and when tasks of each type were chosen by the teacher rather than by the student. In Phase 1, interview and direct observation assessments were conducted to identify relative preferences for academic tasks. In Phase 2, the effects of these lower preference and higher preference tasks on the rate of problem behavior were evaluated using a multielement design. The results showed that lower preference tasks were associated with higher rates of problem behaviors and that students, when given a choice, consistently selected the tasks that had been identified through interview and direct observation as higher preference. In Phase 3, we assessed whether allowing the students to choose between pairs of lower preference tasks or between pairs of higher preference tasks reduced problem behavior relative to a condition in which the teacher selected the same tasks. For 2 of 4 students, the rates of problem behavior were lower when students (rather than the teacher) selected the lower preference activity. Higher preference tasks for 3 students were associated with relatively low rates of problem behavior regardless of whether the student or the teacher selected the task.

Urban environments offer students interesting opportunities to explore and examine how human modified landscapes influence biodiversity, nutrient cycling, and water quality. Students demanding applied field experiences from their undergraduate environmental science (ENVS) programs can be well served in urban settings. Here, we present strategies for integrating urban areas into the undergraduate field experience. Urban locations provide an opportunity for a different type of local "field-work" than would otherwise be available. In the intro level undergraduate ENVS class, we use our campus, the surrounding neighborhood and city as well as a nearby National Park for field exercises. Activities include: assessing water quality from multiple sites, observing species composition and ecological succession using fallen logs, assessing biodiversity using biocubes and camera traps, investigating conservation strategies through the local zoo, and walking one mile transects through local urban ecosystems to observe and collect data on the animals, buildings, roads, litter and/or light sources in the surrounding area. These labs provide inspiration and hands on skills that students apply to their own self-selected projects at the end of the semester. In the second level majors class, we make use of our urban location to contrast water quality in parks and highly channelized urban streams, monitor populations of urban wildlife, and investigate the application of urban greening methods to reduce environmental impacts. Students spend labs immersed in streams and wetlands heavily impacted by the urban runoff their city generates to better understand the extent of human impact in an urban environment. Here we share lesson plans for field activities that can be completed with incoming undergraduate students, and show how these activities help students gain quantitative and investigative competency.

Medical students are the source of a country's physicians. Determining how medical students select their areas of specialization is the key to achieve a balanced distribution of doctors among all specialties. The objective is to identify the number of medical students who have decided their postgraduate specialty career, their career specialties preference, and factors that may influence their decision to select a particular specialty. A facility based cross-sectional study was conducted in September 2013 at Faculty of Medicine, University of Medical Sciences and Technology, Khartoum, Sudan. A self-administered semi-structured questionnaire comprising demographic data and questions about future specialties preferences and factors influencing those preferences was distributed to 887 male and female students, (from first to fifth academic years) recruited in the study. Response rate was 73% with 647 questionnaires collected, out of 887 eligible medical students. Of the returned questionnaires, 604 were valid. The majority of students (541, 89.6%) have chosen a specialty. Surgery, medicine, paediatrics and obstetrics and gynecology were the most selected specialties. The least selected specialty was anaesthesiology. A significant association was found between gender and specialty choice using Chi-square test (p = 0.00). There was no association between undergraduate level and specialty choice (p = 0.633). The most common reason for choosing a specific specialty was "Personal Interest" (215, 39.7%) followed by being "Helpful to the community" (144, 26.6%). Surgery, medicine, paediatrics and obstetrics and gynecology were the most selected specialties.

The potential for utilizing advanced composites in fuselage structures of large transports was assessed. Six fuselage design concepts were selected and evaluated in terms of structural performance, weight, and manufacturing development and costs. Two concepts were selected that merit further consideration for composite fuselage application. These concepts are: (1) a full depth honeycomb design with no stringers, and (2) an I section stringer stiffened laminate skin design. Weight reductions due to applying composites to the fuselages of commercial and military transports were calculated. The benefits of applying composites to a fleet of military transports were determined. Significant technology issues pertinent to composite fuselage structures were identified and evaluated. Program plans for resolving the technology issues were developed.

The purpose of this study was to compare the academic performance of students enrolled in coeducational instruction and single-gender instruction. Within this framework, the researcher examined class type, gender, and racial/ethnicity using the sixth grade CRCT scores of selected students in the areas of mathematics and science. The fifth-grade mathematics and science scores for the same population were used to control for prior knowledge. This study examined the academic achievement of students based on class type, gender, and racial/ethnicity in relation to academic achievement. The study included the CRCT scores for mathematics and science of 6th-grade students at the middle school level who were tested during the 2007--2008 school year. Many studies conducted in the past have stressed females performed better in mathematics and science, while others have stated males performed better in the same areas. Yet, other studies have found conflicting results. A large Australian study (1996), compared the academic performance of students at single-gender and coeducational schools. The conclusion of this study indicated that both males and females who were educated in single-gender classrooms scored significantly higher than did males and females in coeducational classes. A study conducted by Graham Able (2003) documented superior academic performance of students in single-gender schools, after controlling for socioeconomic class and other variables. Able's most significant finding was that the advantage of single-gender schooling was greater for males in terms of academic results than for females. This directly contradicted the educational myth that males performed better in classrooms if females were present. The sample in this study consisted of CRCT scores for 304 sixth-grade students from four different middle schools. Due to the racial composition of the sample, the study only focused on black and white students. School 1 and School 2 involved single-gender instruction while Schools 3 and School 4 involved coeducational instruction. A sample of eighty students was taken from each of the middle schools with single-gender instruction and a sample of 72 students was taken from each of the middle schools with coeducational instruction. Prior to conducting the study, an extensive application was filed with the local board of education to request permission to conduct research in the county. This process involved a detail description of the sample, sampling procedures, sample size, staff members, grade levels, and background information for the study. The major findings in this study indicated that the coeducational students outperformed the single-gender students and the white students outperformed the black students. This study confirmed that white coeducational students performed significantly higher than the black coeducational students. It was also documented through this study that there was no significant difference between the performance of the single-gender black students and the single-gender white students. In contrast to the Australian study (1996), this study indicated that the coeducational students were outperforming the single-gender students. In comparison to the 2003 study by Able, the findings of this study showed single-gender instruction was greater for females in terms of higher academic achievement than for males. INDEX WORDS.

Developing and testing the CHORDS: Characteristics of Responsible Drinking Survey.
Barry, Adam E; Goodson, Patricia
2011-01-01
Report on the development and psychometric testing of a theoretically and evidence-grounded instrument, the Characteristics of Responsible Drinking Survey (CHORDS). Instrument subjected to four phases of pretesting (cognitive validity, cognitive and motivational qualities, pilot test, and item evaluation) and a final posttest implementation. Large public university in Texas. Randomly selected convenience sample (n = 729) of currently enrolled students. This 78-item questionnaire measures individuals' responsible drinking beliefs, motivations, intentions, and behaviors. Cronbach α, split-half reliability, principal components analysis and Spearman ρ were conducted to investigate reliability, stability, and validity. Measures in the CHORDS exhibited high internal consistency reliability and strong correlations of split-half reliability. Factor analyses indicated five distinct scales were present, as proposed in the theoretical model. Subscale composite scores also exhibited a correlation to alcohol consumption behaviors, indicating concurrent validity. The CHORDS represents the first instrument specifically designed to assess responsible drinking beliefs and behaviors. It was found to elicit valid and reliable data among a college student sample. This instrument holds much promise for practitioners who desire to empirically investigate dimensions of responsible drinking.

A qualitative study on using concept maps in problem-based learning.
Chan, Zenobia C Y
2017-05-01
The visual arts, including concept maps, have been shown to be effective tools for facilitating student learning. However, the use of concept maps in nursing education has been under-explored. The aim of this study was to explore how students develop concept maps and what these concept maps consist of, and their views on the use of concept maps as a learning activity in a PBL class. A qualitative approach consisting of an analysis of the contents of the concept maps and interviews with students. The study was conducted in a school of nursing in a university in Hong Kong. A total of 38 students who attended the morning session (20 students) and afternoon session (18 students) respectively of a nursing problem-based learning class. The students in both the morning and afternoon classes were allocated into four groups (4-5 students per group). Each group was asked to draw two concept maps based on a given scenario, and then to participate in a follow-up interview. Two raters individually assessed the concept maps, and then discussed their views with each other. Among the concept maps that were drawn, four were selected. Their four core features of those maps were: a) the integration of informative and artistic elements; b) the delivery of sensational messages; c) the use of images rather than words; and d) three-dimensional and movable. Both raters were concerned about how informative the presentation was, the composition of the elements, and the ease of comprehension, and appreciated the three-dimensional presentation and effective use of images. From the results of the interview, the pros and cons of using concept maps were discerned. This study demonstrated how concept maps could be implemented in a PBL class to boost the students' creativity and to motivate them to learn. This study suggests the use of concept maps as an initiative to motivate student to learn, participate actively, and nurture their creativity. To conclude, this study explored an alternative way for students to make presentations and pioneered the use of art-based concept maps to facilitate student learning. Copyright © 2017 Elsevier Ltd.

The relation of LD and gender with emotional intelligence in college students.
Reiff, H B; Hatzes, N M; Bramel, M H; Gibbon, T
2001-01-01
This study examined the relation of learning disabilities (LD) and gender with emotional intelligence in 128 college students. Fifty-four students with LD (32 men and 22 women) and 74 without LD (34 men and 40 women) attending two colleges and one university participated in the study. Emotional intelligence was assessed using the Emotional Quotient Inventory (EQ-i; BarOn,1997), a self-report instrument designed to measure interpersonal and intrapersonal skills, stress management, adaptability, and general mood. A 2-way multivariate analysis of variance (MANOVA) was performed to examine the main effects of LD and gender and the interaction of the two main effects on the five composites of the EQ-i. Students with LD had fewer credits and lower scholastic aptitude test (SAT) scores, high school grade point averages (GPAs), and college GPAs than students without LD; women students were older and had higher college GPAs than men students. Results of the MANOVA indicated significant main effects of both LD and gender; no significant interaction occurred. Post hoc univariate analyses of the five composites revealed significant differences between students with LD and students without LD on stress management and adaptability, significant differences between men and women students on interpersonal skills, and significant differences of the interaction of LD and gender on interpersonal skills.
Hypothesis-driven physical examination curriculum.

Medical students traditionally learn physical examination skills as a rote list of manoeuvres. Alternatives like hypothesis-driven physical examination (HDPE) may promote students' understanding of the contribution of physical examination to diagnostic reasoning. We sought to determine whether first-year medical students can effectively learn to perform a physical examination using an HDPE approach, and then tailor the examination to specific clinical scenarios. Medical students traditionally learn physical examination skills as a rote list of manoeuvres CONTEXT: First-year medical students at the University of Minnesota were taught both traditional and HDPE approaches during a required 17-week clinical skills course in their first semester. The end-of-course evaluation assessed HDPE skills: students were assigned one of two cardiopulmonary cases. Each case included two diagnostic hypotheses. During an interaction with a standardised patient, students were asked to select physical examination manoeuvres in order to make a final diagnosis. Items were weighted and selection order was recorded. First-year students with minimal pathophysiology performed well. All students selected the correct diagnosis. Importantly, students varied the order when selecting examination manoeuvres depending on the diagnoses under consideration, demonstrating early clinical decision-making skills. An early introduction to HDPE may reinforce physical examination skills for hypothesis generation and testing, and can foster early clinical decision-making skills. This has important implications for further research in physical examination instruction. © 2016 John Wiley & Sons Ltd and The Association for the Study of Medical Education.
