    Full Text Available Applied researchers have employed chi-square tests for more than one hundred years. This paper addresses the question of how one should follow a statistically significant chi-square test result in order to determine the source of that result. Four approaches were evaluated: calculating residuals, comparing cells, ransacking, and partitioning. Data from two recent journal articles were used to illustrate these approaches. A call is made for greater consideration of foundational techniques such as the chi-square tests.

    Full Text Available In medical research, there are studies which often collect data on categorical variables that can be summarized as a series of counts. These counts are commonly arranged in a tabular format known as a contingency table. The chi-square test statistic can be used to evaluate whether there is an association between the rows and columns in a contingency table. More specifically, this statistic can be used to determine whether there is any difference between the study groups in the proportions of the risk factor of interest. Chi-square test and the logic of hypothesis testing were developed by Karl Pearson. This article describes in detail what is a chi-square test, on which type of data it is used, the assumptions associated with its application, how to manually calculate it and how to make use of an online calculator for calculating the Chi-square statistics and its associated P-value.

    Chi-square discriminatory veto is a computationally expensive signal based veto as it requires lots of computing time. This veto is applied to the triggers surviving the second stage of the pipeline in the inspiral searches. We shall make an attempt to understand the nature of this veto and whether we can predict the chi-square values of triggers surviving this computationally expensive veto. This veto helps us to discriminate real signals from those arising due to noise transients by measuring the goodness of fit quantity. We discuss here two separate approaches. One is purely analytical which is based on the power accumulated in a given frequency bin due to the presence of non-stationary and non-Gaussian noise. We know that sum of squares of Gaussian random variables follow a central chi-square distribution whereas in case on non-Gaussian noise they obey a non-central chi-square distribution and hence the mean value has a contribution from central part non-central parameter λ. We shall show that this non-central parameter λ is a function of signal to noise ratio (SNR) of the triggers. Thus enabling us to model the expected chi-square values of the triggers using the SNR. The second approach I will talk involves trying to obtain a parabolic fit to the measured chi-squared distribution for a range of values as a function of signal to noise ratio.

  11. Noncentral Chi-Square Versus Normal Distributions in Describing the Likelihood Ratio Statistic: The Univariate Case and Its Multivariate Implication.

    Science.gov (United States)

    Yuan, Ke-Hai

    2008-01-01

    In the literature of mean and covariance structure analysis, noncentral chi-square distribution is commonly used to describe the behavior of the likelihood ratio (LR) statistic under alternative hypothesis. Due to the inaccessibility of the rather technical literature for the distribution of the LR statistic, it is widely believed that the noncentral chi-square distribution is justified by statistical theory. Actually, when the null hypothesis is not trivially violated, the noncentral chi-square distribution cannot describe the LR statistic well even when data are normally distributed and the sample size is large. Using the one-dimensional case, this article provides the details showing that the LR statistic asymptotically follows a normal distribution, which also leads to an asymptotically correct confidence interval for the discrepancy between the null hypothesis/model and the population. For each one-dimensional result, the corresponding results in the higher dimensional case are pointed out and references are provided. Examples with real data illustrate the difference between the noncentral chi-square distribution and the normal distribution. Monte Carlo results compare the strength of the normal distribution against that of the noncentral chi-square distribution. The implication to data analysis is discussed whenever relevant. The development is built upon the concepts of basic calculous, linear algebra, and introductory probability and statistics. The aim is to provide the least technical material for quantitative graduate students in social science to understand the condition and limitation of the noncentral chi-square distribution.

    2006-01-01

    Binary outcomes that depend on an ordinal predictor in a non-monotonic way are common in medical data analysis. Such patterns can be addressed in terms of cutpoints: for example, one looks for two cutpoints that define an interval in the range of the ordinal predictor for which the probability of a positive outcome is particularly high (or low). A chi-square test may then be performed to compare the proportions of positive outcomes in and outside this interval. However, if the two cutpoints a...

  13. Chi-Squared Distance Metric Learning for Histogram Data

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Learning a proper distance metric for histogram data plays a crucial role in many computer vision tasks. The chi-squared distance is a nonlinear metric and is widely used to compare histograms. In this paper, we show how to learn a general form of chi-squared distance based on the nearest neighbor model. In our method, the margin of sample is first defined with respect to the nearest hits (nearest neighbors from the same class and the nearest misses (nearest neighbors from the different classes, and then the simplex-preserving linear transformation is trained by maximizing the margin while minimizing the distance between each sample and its nearest hits. With the iterative projected gradient method for optimization, we naturally introduce the l2,1 norm regularization into the proposed method for sparse metric learning. Comparative studies with the state-of-the-art approaches on five real-world datasets verify the effectiveness of the proposed method.

    Ley, Christopher P.; Orchard, Marcos E.

    2017-01-01

    This paper presents a novel form of selecting the likelihood function of the standard sequential importance sampling/re-sampling particle filter (SIR-PF) with a combination of sliding window smoothing and chi-square statistic weighting, so as to: (a) increase the rate of convergence of a flexible state model with artificial evolution for online parameter learning (b) improve the performance of a particle-filter based prognosis algorithm. This is applied and tested with real data from oil total base number (TBN) measurements from three haul trucks. The oil data has high measurement uncertainty and an unknown phenomenological state model. Performance of the proposed algorithm is benchmarked against the standard form of SIR-PF estimation which utilises the Normal (Gaussian) likelihood function. Both implementations utilise the same particle filter based prognosis algorithm so as to provide a common comparison. A sensitivity analysis is also performed to further explore the effects of the combination of sliding window smoothing and chi-square statistic weighting to the SIR-PF.

    The Goddard Space Flight Center (GSFC) Flight Dynamics Facility (FDF) performs orbit determination (OD) for the Aqua and Aura satellites. Both satellites are located in low Earth orbit (LEO), and are part of what is considered the A-Train satellite constellation. Both spacecraft are currently in the science phase of their respective missions. The FDF has recently been tasked with delivering definitive covariance for each satellite.The main source of orbit determination used for these missions is the Orbit Determination Toolkit developed by Analytical Graphics Inc. (AGI). This software uses an Extended Kalman Filter (EKF) to estimate the states of both spacecraft. The filter incorporates force modelling, ground station and space network measurements to determine spacecraft states. It also generates a covariance at each measurement. This covariance can be useful for evaluating the overall performance of the tracking data measurements and the filter itself. An accurate covariance is also useful for covariance propagation which is utilized in collision avoidance operations. It is also valuable when attempting to determine if the current orbital solution will meet mission requirements in the future.This paper examines the use of the Chi-square statistic as a means of evaluating filter performance. The Chi-square statistic is calculated to determine the realism of a covariance based on the prediction accuracy and the covariance values at a given point in time. Once calculated, it is the distribution of this statistic that provides insight on the accuracy of the covariance.For the EKF to correctly calculate the covariance, error models associated with tracking data measurements must be accurately tuned. Over estimating or under estimating these error values can have detrimental effects on the overall filter performance. The filter incorporates ground station measurements, which can be tuned based on the accuracy of the individual ground stations. It also includes

    Full Text Available The main purpose of this article is to do approximations graphically and mathematically the four-parameter generalized log-logistic distribution, denoted by G4LL(α,β,m_1,m_2, to the one-parameter Chi-square distribution with υ degrees of freedom. In order to achieve this purpose, this article creates graphically the probability density functions of both distribution and derives mathematically the MGF of the both distributions. To prove the MGF of Chi-square as a special case of the MGF of G4LL distribution, we utilized an expansion of the MacLaurin series. The results show that graphically, the Chi-square distribution can be approximated by the generalized log-logistic distribution. Moreover, by letting α=1,β=-ln⁡(2m_2 ,m_1=v/2 and m_2→∞, the MGF of the G4LL distribution can be written in the form of the MGF of the Chi-square distribution. Thus, the Chi-square distribution is a limiting or special case distribution of the generalized log-logistic distribution.The main purpose of this article is to do approximations graphically and mathematically the four-parameter generalized log-logistic distribution, denoted by G4LL(α,β,m_1,m_2, to the one-parameter Chi-square distribution with υ degrees of freedom.

  19. Understanding statistical power using noncentral probability distributions: Chi-squared, G-squared, and ANOVA

    2007-09-01

    Full Text Available This paper presents a graphical way of interpreting effect sizes when more than two groups are involved in a statistical analysis. This method uses noncentral distributions to specify the alternative hypothesis, and the statistical power can thus be directly computed. This principle is illustrated using the chi-squared distribution and the F distribution. Examples of chi-squared and ANOVA statistical tests are provided to further illustrate the point. It is concluded that power analyses are an essential part of statistical analysis, and that using noncentral distributions provides an argument in favour of using a factorial ANOVA over multiple t tests.

  1. Measurement invariance via multigroup SEM: Issues and solutions with chi-square-difference tests.

    Yuan, Ke-Hai; Chan, Wai

    2016-09-01

    Multigroup structural equation modeling (SEM) plays a key role in studying measurement invariance and in group comparison. When population covariance matrices are deemed not equal across groups, the next step to substantiate measurement invariance is to see whether the sample covariance matrices in all the groups can be adequately fitted by the same factor model, called configural invariance. After configural invariance is established, cross-group equalities of factor loadings, error variances, and factor variances-covariances are then examined in sequence. With mean structures, cross-group equalities of intercepts and factor means are also examined. The established rule is that if the statistic at the current model is not significant at the level of .05, one then moves on to testing the next more restricted model using a chi-square-difference statistic. This article argues that such an established rule is unable to control either Type I or Type II errors. Analysis, an example, and Monte Carlo results show why and how chi-square-difference tests are easily misused. The fundamental issue is that chi-square-difference tests are developed under the assumption that the base model is sufficiently close to the population, and a nonsignificant chi-square statistic tells little about how good the model is. To overcome this issue, this article further proposes that null hypothesis testing in multigroup SEM be replaced by equivalence testing, which allows researchers to effectively control the size of misspecification before moving on to testing a more restricted model. R code is also provided to facilitate the applications of equivalence testing for multigroup SEM. (PsycINFO Database Record

  2. Chi-square Fitting When Overall Normalization is a Fit Parameter

    CERN Document Server

    Roe, Byron

    2015-01-01

    The problem of fitting an event distribution when the total expected number of events is not fixed, keeps appearing in experimental studies. In a chi-square fit, if overall normalization is one of the parameters parameters to be fit, the fitted curve may be seriously low with respect to the data points, sometimes below all of them. This problem and the solution for it are well known within the statistics community, but, apparently, not well known among some of the physics community. The purpose of this note is didactic, to explain the cause of the problem and the easy and elegant solution. The solution is to use maximum likelihood instead of chi-square. The essential difference between the two approaches is that maximum likelihood uses the normalization of each term in the chi-square assuming it is a normal distribution, 1/sqrt(2 pi sigma-square). In addition, the normalization is applied to the theoretical expectation not to the data. In the present note we illustrate what goes wrong and how maximum likeliho...

    In goodness-of-fit tests,Pearson's chi-squared test is one of most widely used tools of formal statistical analysis.However,Pearson's chi-squared test depends on the partition of the sample space.Different constructions of the partition of the sample space may lead to different conclusions.Based on an equiprobable partition of sample space,a modified chi-squared test is proposed.A method for constructing the modified chi-squared test is proposed.As an application,the proposed test is used to test whether vectorial data come from an uniformity distribution defined on the hypersphere.Some simulation studies show that the modified chi-squared test against different alternative is robust.

    2010-01-01

    Objectives: Text categorization has been used in biomedical informatics for identifying documents containing relevant topics of interest. We developed a simple method that uses a chi-square-based scoring function to determine the likelihood of MEDLINE citations containing genetic relevant topic. Methods: Our procedure requires construction of a genetic and a nongenetic domain document corpus. We used MeSH descriptors assigned to MEDLINE citations for this categorization task. We compared frequencies of MeSH descriptors between two corpora applying chi-square test. A MeSH descriptor was considered to be a positive indicator if its relative observed frequency in the genetic domain corpus was greater than its relative observed frequency in the nongenetic domain corpus. The output of the proposed method is a list of scores for all the citations, with the highest score given to those citations containing MeSH descriptors typical for the genetic domain. Results: Validation was done on a set of 734 manually annotate...

    Given the vast reservoirs of data stored worldwide, efficient mining of data from a large information store has emerged as a great challenge. Many databases like that of intrusion detection systems, web-click records, player statistics, texts, proteins etc., store strings or sequences. Searching for an unusual pattern within such long strings of data has emerged as a requirement for diverse applications. Given a string, the problem then is to identify the substrings that differs the most from the expected or normal behavior, i.e., the substrings that are statistically significant. In other words, these substrings are less likely to occur due to chance alone and may point to some interesting information or phenomenon that warrants further exploration. To this end, we use the chi-square measure. We propose two heuristics for retrieving the top-k substrings with the largest chi-square measure. We show that the algorithms outperform other competing algorithms in the runtime, while maintaining a high approximation...

    2007-02-01

    Full Text Available Abstract Background Boolean network (BN modeling is a commonly used method for constructing gene regulatory networks from time series microarray data. However, its major drawback is that its computation time is very high or often impractical to construct large-scale gene networks. We propose a variable selection method that are not only reduces BN computation times significantly but also obtains optimal network constructions by using chi-square statistics for testing the independence in contingency tables. Results Both the computation time and accuracy of the network structures estimated by the proposed method are compared with those of the original BN methods on simulated and real yeast cell cycle microarray gene expression data sets. Our results reveal that the proposed chi-square testing (CST-based BN method significantly improves the computation time, while its ability to identify all the true network mechanisms was effectively the same as that of full-search BN methods. The proposed BN algorithm is approximately 70.8 and 7.6 times faster than the original BN algorithm when the error sizes of the Best-Fit Extension problem are 0 and 1, respectively. Further, the false positive error rate of the proposed CST-based BN algorithm tends to be less than that of the original BN. Conclusion The CST-based BN method dramatically improves the computation time of the original BN algorithm. Therefore, it can efficiently infer large-scale gene regulatory network mechanisms.

    2005-01-01

    Full Text Available An important function of a hospital’s Infectious Disease and Pharmacy programs is to review and compare the most recent antibiogram with that of the previous year to determine if significant changes in antibiotic susceptibility results are noted and to communicate this information and its consequences to the medical staff. However, there are currently no formal analytical (decision-making models in use to determine if the rate of resistance to an antibiotic from one year to the next has significantly changed more or less than one would expect due to sampling error and test reliability. The purpose of this article, therefore, is to demonstrate the utility of using a well-established and simple nonparametric statistical technique (chi-square for analyzing annual variations in cumulative antibiogram data and to determine whether such variations are significantly different from chance and to what to degree. The chi-square model outlined here is a simple, practical, quick, low burden and easy to understand and execute approach that greatly improves the analysis of antibiogram data and decision-making by practitioners. More work and research is needed to develop additional inferential statistical methods and models that can be applied to antibiogram data.

  11. Students Discover Unique Planet

    Three undergraduate students, from Leiden University in the Netherlands, have discovered an extrasolar planet. The extraordinary find, which turned up during their research project, is about five times as massive as Jupiter. This is also the first planet discovered orbiting a fast-rotating hot star. Omega Centauri ESO PR Photo 45a/08 A planet around a hot star The students were testing a method of investigating the light fluctuations of thousands of stars in the OGLE database in an automated way. The brightness of one of the stars was found to decrease for two hours every 2.5 days by about one percent. Follow-up observations, taken with ESO's Very Large Telescope in Chile, confirmed that this phenomenon is caused by a planet passing in front of the star, blocking part of the starlight at regular intervals. According to Ignas Snellen, supervisor of the research project, the discovery was a complete surprise. "The project was actually meant to teach the students how to develop search algorithms. But they did so well that there was time to test their algorithm on a so far unexplored database. At some point they came into my office and showed me this light curve. I was completely taken aback!" The students, Meta de Hoon, Remco van der Burg, and Francis Vuijsje, are very enthusiastic. "It is exciting not just to find a planet, but to find one as unusual as this one; it turns out to be the first planet discovered around a fast rotating star, and it's also the hottest star found with a planet," says Meta. "The computer needed more than a thousand hours to do all the calculations," continues Remco. The planet is given the prosaic name OGLE2-TR-L9b. "But amongst ourselves we call it ReMeFra-1, after Remco, Meta, and myself," says Francis. The planet was discovered by looking at the brightness variations of about 15 700 stars, which had been observed by the OGLE survey once or twice per night for about four years between 1997 and 2000. Because the data had been made public

    2013-01-01

    The Kepler spacecraft observes a host of target stars to detect transiting planets. Requiring a 7.1 sigma detection in twelve quarters of data yields over 100,000 detections, many of which are false alarms. After a second cut is made on a robust detection statistic, some 50,000 or more targets still remain. These false alarms waste resources as they propagate through the remainder of the software pipeline and so a method to discriminate against them is crucial in maintaining the desired sensitivity to true events. This paper describes a chi-square test which represents a novel application of the formalism developed by Allen for false alarm mitigation in searches for gravitational waves. Using this technique, the false alarm rate can be lowered to ~5%.

    2001-01-01

    Objective This paper propses a family of summary chi square tests for comparing survival rates at all points of time between two groups. Methods They are respectively derived from the Peto et al. expression for the log rank test, the Mantel-Haenszel expression for the log rank test, and the generalized Wilcoxon test by means of using the homogenetic effective sample size in place of the number at risk and using the corresponding numerator of the conditional probability surviving in place of the death number. Results After such derivations they become clearer in clinical significance, more powerful, and free from the assumption of proportional hazard. Conclusion These tests can be employed in analyzing the clinical data of cancer. A worked example illustrates the methodology.

    Full Text Available This study explored the reduction of adenosine triphosphate (ATP levels in L-02 hepatocytes by hexavalent chromium (Cr(VI using chi-square analysis. Cells were treated with 2, 4, 8, 16, or 32 μM Cr(VI for 12, 24, or 36 h. Methyl thiazolyl tetrazolium (MTT experiments and measurements of intracellular ATP levels were performed by spectrophotometry or bioluminescence assays following Cr(VI treatment. The chi-square test was used to determine the difference between cell survival rate and ATP levels. For the chi-square analysis, the results of the MTT or ATP experiments were transformed into a relative ratio with respect to the control (%. The relative ATP levels increased at 12 h, decreased at 24 h, and increased slightly again at 36 h following 4, 8, 16, 32 μM Cr(VI treatment, corresponding to a "V-shaped" curve. Furthermore, the results of the chi-square analysis demonstrated a significant difference of the ATP level in the 32-μM Cr(VI group (P < 0.05. The results suggest that the chi-square test can be applied to analyze the interference effects of Cr(VI on ATP levels in L-02 hepatocytes. The decreased ATP levels at 24 h indicated disruption of mitochondrial energy metabolism and the slight increase of ATP levels at 36 h indicated partial recovery of mitochondrial function or activated glycolysis in L-02 hepatocytes.

    Littering is not a novelty, yet a prolonged issue. The solutions have been discussed for a long time; however this issue still remains unresolved. Littering is commonly associated with littering behavior and awareness. The littering behavior is normally influenced by the litter profile such as gender, family income, education level and age. Jengka Street market, which is located in Pahang, is popularly known as a trade market. It offers diversities of wet and dry goods and is awaited by local residents and tourists. This study analyzes association between litterers' profile and littering behavior. Littering behavior is measured based on factors of trash bin facilities, awareness campaign and public littering behavior. 114 respondents were involved in this study with 62 (54.39%) are female aged more than 18 years old and majority of these female respondents are diploma holders. In addition, 78.95% of the respondents have family income below than RM3,000.00 per month. Based on the data analysis, it was found that first-time visitors littered higher than frequent visitors, lack of providing trash bin facilities contributes to positive littering behavior and there is a significant association between litterers' age and littering behavior by using chi-square approach.

  18. A Precise Distance Metric for Mixed Data Clustering using Chi-square Statistics

    Full Text Available In today's scenario, data is available as a mix of numerical and categorical values. Traditional data clustering algorithms perform well for numerical data but produce poor clustering results for mixed data. For better partitioning, the distance metric used should be capable of discriminating the data points with mixed attributes. The distance measure should appropriately balance the categorical distance as well as numerical distance. In this study we have proposed a chi-square based statistical approach to determine the weight of the attributes. This weight vector is used to derive the distance matrix of the mixed dataset. The distance matrix is used to cluster the data points using the traditional clustering algorithms. Experiments have been carried out using the UCI benchmark datasets, heart, credit and vote. Apart from these data sets we have also tested our proposed method using a real-time bank data set. The accuracy of the clustering results obtained are better than those of the existing works.

    RM CLEAN is a standard method to reconstruct the distribution of cosmic magnetic fields and polarized sources along the line of sight (LOS) from observed polarization spectrum. This method is similar to the CLEAN algorithm for aperture synthesis radio telescope images but it is rather unclear in what cases RM CLEAN works well. In this paper, we evaluate the performance of RM CLEAN by simulating spectro-polarimetric observations of two compact sources located in the same LOS, varying the relative initial polarization angle and Faraday depth systematically. Especially, we focus on if the two polarized sources can be resolved in the Faraday depth space and how well the source parameters can be estimated. We confirm the previous studies that two sources cannot be resolved when they are closely located in the Faraday depth space for specific values of the relative initial polarization angle. Further, we calculate the chi-square value for the fit between the mock data of polarization spectrum and the one from RM CL...

    2016-11-02

    Motivated by the key importance of multi-sensor information fusion algorithms in the state-of-the-art integrated navigation systems due to recent advancements in sensor technologies, telecommunication, and navigation systems, the paper proposes an improved and innovative fault-tolerant fusion framework. An integrated navigation system is considered consisting of four sensory sub-systems, i.e., Strap-down Inertial Navigation System (SINS), Global Navigation System (GPS), the Bei-Dou2 (BD2) and Celestial Navigation System (CNS) navigation sensors. In such multi-sensor applications, on the one hand, the design of an efficient fusion methodology is extremely constrained specially when no information regarding the system's error characteristics is available. On the other hand, the development of an accurate fault detection and integrity monitoring solution is both challenging and critical. The paper addresses the sensitivity issues of conventional fault detection solutions and the unavailability of a precisely known system model by jointly designing fault detection and information fusion algorithms. In particular, by using ideas from Interacting Multiple Model (IMM) filters, the uncertainty of the system will be adjusted adaptively by model probabilities and using the proposed fuzzy-based fusion framework. The paper also addresses the problem of using corrupted measurements for fault detection purposes by designing a two state propagator chi-square test jointly with the fusion algorithm. Two IMM predictors, running in parallel, are used and alternatively reactivated based on the received information form the fusion filter to increase the reliability and accuracy of the proposed detection solution. With the combination of the IMM and the proposed fusion method, we increase the failure sensitivity of the detection system and, thereby, significantly increase the overall reliability and accuracy of the integrated navigation system. Simulation results indicate that the

    Full Text Available In efforts to discover disease mechanisms and improve clinical diagnosis of tumors, it is useful to mine profiles for informative genes with definite biological meanings and to build robust classifiers with high precision. In this study, we developed a new method for tumor-gene selection, the Chi-square test-based integrated rank gene and direct classifier (χ2-IRG-DC. First, we obtained the weighted integrated rank of gene importance from chi-square tests of single and pairwise gene interactions. Then, we sequentially introduced the ranked genes and removed redundant genes by using leave-one-out cross-validation of the chi-square test-based Direct Classifier (χ2-DC within the training set to obtain informative genes. Finally, we determined the accuracy of independent test data by utilizing the genes obtained above with χ2-DC. Furthermore, we analyzed the robustness of χ2-IRG-DC by comparing the generalization performance of different models, the efficiency of different feature-selection methods, and the accuracy of different classifiers. An independent test of ten multiclass tumor gene-expression datasets showed that χ2-IRG-DC could efficiently control overfitting and had higher generalization performance. The informative genes selected by χ2-IRG-DC could dramatically improve the independent test precision of other classifiers; meanwhile, the informative genes selected by other feature selection methods also had good performance in χ2-DC.

  7. Statistics of the Chi-Square Type, with Application to the Analysis of Multiple Time-Series Power Spectra

    2003-01-01

    It is often necessary to compare the power spectra of two or more time series: one may, for instance, wish to estimate what the power spectrum of the combined data sets might have been, or one may wish to estimate the significance of a particular peak that shows up in two or more power spectra. Also, one may occasionally need to search for a complex of peaks in a single power spectrum, such as a fundamental and one or more harmonics, or a fundamental plus sidebands, etc. Visual inspection can be revealing, but it can also be misleading. This leads one to look for one or more ways of forming statistics, which readily lend themselves to significance estimation, from two or more power spectra. The familiar chi-square statistic provides a convenient mechanism for combining variables drawn from normal distributions, and one may generalize the chi-square statistic to be any function of any number of variables with arbitrary distributions. In dealing with power spectra, we are interested mainly in exponential distri...

    Gene-gene interaction studies focus on the investigation of the association between the single nucleotide polymorphisms (SNPs) of genes for disease susceptibility. Statistical methods are widely used to search for a good model of gene-gene interaction for disease analysis, and the previously determined models have successfully explained the effects between SNPs and diseases. However, the huge numbers of potential combinations of SNP genotypes limit the use of statistical methods for analysing high-order interaction, and finding an available high-order model of gene-gene interaction remains a challenge. In this study, an improved particle swarm optimization with double-bottom chaotic maps (DBM-PSO) was applied to assist statistical methods in the analysis of associated variations to disease susceptibility. A big data set was simulated using the published genotype frequencies of 26 SNPs amongst eight genes for breast cancer. Results showed that the proposed DBM-PSO successfully determined two- to six-order models of gene-gene interaction for the risk association with breast cancer (odds ratio > 1.0; P value <0.05). Analysis results supported that the proposed DBM-PSO can identify good models and provide higher chi-square values than conventional PSO. This study indicates that DBM-PSO is a robust and precise algorithm for determination of gene-gene interaction models for breast cancer.

The Project specification is to analyse the result of a weekly data produced by Compact Muon Solenoid (CMS) in the form of histograms. CMS is a detector which is a multi-purpose apparatus use to operate at the Large Hadron Collider (LHC) at CERN. It will yield head-on collisions of two proton (ion) beams of 7 TeV (2.75 TeV per nucleon) each, with a design luminosity of 10 34 cm -2s-1. A comparison of the results is then made using two methods namely Kolmogorov Smirnov Statistic Test and Chi-Squared Test. These tests will be further elaborated in the subsequent paragraphs. To execute this project, I have to firstly study the entire basic computer programming in particular C++ and the ROOT Basic Programmes. This is important to ensure the tasks given can be resolved within the given time. A program is subsequently written to provide output of histogram and calculation of Kolmogorov-Smirnov Test and Ch...

    Demonstration of equivalence in aerodynamic particle size distribution (APSD) is one key component for establishing bioequivalence of orally inhaled drug products. We previously proposed a modified version of the Chi-square ratio statistic (mCSRS) for APSD equivalence testing and demonstrated that the median of the distribution of the mCSRS (MmCSRS) is a robust metric when test (T) and reference (R) cascade impactor (CI) profiles are identical. Here, we systematically evaluate the behavior of the MmCSRS when T and R CI profiles differ from each other in their mean deposition and variability on a single and multiple sites. All CI profiles were generated by Monte-Carlo simulations based upon modified actual CI data. Twenty thousand sets of 30 T and 30 R CI profiles were simulated for each scenario, and the behavior of the MmCSRS was correlated to metrics that characterize the difference between T and R product in mean deposition and variability. The two key findings were, first, that the MmCSRS is more sensitive to difference between T and R CI profiles on high deposition sites, and second, that a cut-off value for APSD equivalence testing based on the MmCSRS needs to be scaled on the variability of the R product. The former is considered as beneficial for equivalence testing of CI profiles as it decreases the likelihood of failing identical CI profiles by chance, in part, due to increasing analytical variability associated with lower deposition sites. The latter is expected to be important for consistently being able to discriminate equivalent from inequivalent CI profiles.

    Optometric education has been faced with ever-increasing expectations. These include the ability to educate students and practitioners to care for new patient populations, deal with more diverse and complex clinical problems, to be significant participants in the research community and to fulfill leadership positions within the profession. To fulfill this expectation, schools and colleges need to diversify their program offerings to attract and educate unique student populations who come from diverse backgrounds and bring a range of pre-existing knowledge and skills. This paper provides an overview of The New England College of Optometry's efforts in this area and two programs, the "Advanced Standing International Program" and the "Accelerated Doctor of Optometry Degree Program," are examined in detail. An emphasis is placed on outcomes assessment to ensure the programs are fulfilling their purpose and the results of a retrospective analysis of the two programs is provided.

    2012-12-01

    This dissertation describes the results of a WIMP search using CDMS II data sets accumulated at the Soudan Underground Laboratory in Minnesota. Results from the original analysis of these data were published in 2009; two events were observed in the signal region with an expected leakage of 0.9 events. Further investigation revealed an issue with the ionization-pulse reconstruction algorithm leading to a software upgrade and a subsequent reanalysis of the data. As part of the reanalysis, I performed an advanced discrimination technique to better distinguish (potential) signal events from backgrounds using a 5-dimensional chi-square method. This dataanalysis technique combines the event information recorded for each WIMP-search event to derive a backgrounddiscrimination parameter capable of reducing the expected background to less than one event, while maintaining high efficiency for signal events. Furthermore, optimizing the cut positions of this 5-dimensional chi-square parameter for the 14 viable germanium detectors yields an improved expected sensitivity to WIMP interactions relative to previous CDMS results. This dissertation describes my improved (and optimized) discrimination technique and the results obtained from a blind application to the reanalyzed CDMS II WIMP-search data.

    In this thesis I present a software framework for use on the ATLAS muon CSC readout driver. This C++ framework uses plug-in Decoders incorporating hand-optimized assembly language routines to perform sparsification and data formatting. The software is designed with both flexibility and performance in mind, and runs on a custom 9U VME board using Texas Instruments TMS360C6203 digital signal processors. I describe the requirements of the software, the methods used in its design, and the results of testing the software with simulated data. I also present modifications to a chi-squared analysis of the Standard Model and Four Down Quark Model (FDQM) originally done by Dr. Dennis Silverman. The addition of four new experiments to the analysis has little effect on the Standard Model but provides important new restrictions on the FDQM. The method used to incorporate these new experiments is presented, and the consequences of their addition are reviewed.

    In times of scarce resources it is important for services to make evidence based decisions when identifying clients with poor outcomes. chi-Squared Automatic Interaction Detection (CHAID) modelling was used to identify characteristics of clients experiencing statistically significant poor outcomes. A national, longitudinal study recruited and interviewed, using the Maudsley Addiction Profile (MAP), 215 clients starting methadone treatment and 78% were interviewed one year later. Four CHAID analyses were conducted to model the interactions between the primary outcome variable, used heroin in the last 90 days prior to one year interview and variables on drug use, treatment history, social functioning and demographics. Results revealed that regardless of these other variables, males over 22 years of age consistently demonstrated significantly poorer outcomes than all other clients. CHAID models can be easily applied by service providers to provide ongoing evidence on clients exhibiting poor outcomes and requiring priority within services.

Patient disease was classified according to CHAID classification trees and the TNM classification, and the results were compared. Academic research. A total of 3373 patients with carcinoma of the oral cavity, oropharynx, hypopharynx, or larynx. The 2 classification methods were evaluated objectively, measuring intrastage homogeneity (hazard consistency), interstage heterogeneity (hazard discrimination), and disease stage distribution among patients (balance). In addition, to assess agreement between CHAID classification trees and the TNM classification, we calculated the κ statistic, weighted linearly and quadratically. Objective evaluation of the quality of the classification methods indicated that CHAID classification trees performed better than the TNM classification in terms of hazard consistency (2.51 for CHAID and 3.01 for TNM) and hazard discrimination (70.9% for CHAID and 52.7% for TNM) but not balance (-31.7% for CHAID and -15.5% for TNM). Analysis of concordance between the classification methods showed that the quadratic κ statistic was 0.77 (95% CI, 0.76-0.78) and the linear κ statistic was 0.59 (95% CI, 0.57-0.60) (P TNM classification and offer potential inclusion of new prognostic factors.

    When using parametric empirical Bayes estimation methods for estimating the binomial or Poisson parameter, the validity of the assumed beta or gamma conjugate prior distribution is an important diagnostic consideration. Chi-square goodness-of-fit tests of the beta or gamma prior hypothesis are developed for use when the binomial sample sizes or Poisson exposure times vary. Nine examples illustrate the application of the methods, using real data from such diverse applications as the loss of feedwater flow rates in nuclear power plants, the probability of failure to run on demand and the failure rates of the high pressure coolant injection systems at US commercial boiling water reactors, the probability of failure to run on demand of emergency diesel generators in US commercial nuclear power plants, the rate of failure of aircraft air conditioners, baseball batting averages, the probability of testing positive for toxoplasmosis, and the probability of tumors in rats. The tests are easily applied in practice by means of corresponding Mathematica{reg_sign} computer programs which are provided.

    Demonstration of equivalence in aerodynamic particle size distribution (APSD; e.g., by comparing cascade impactor (CI) profiles) constitutes one of key in vitro tests for supporting bioequivalence between test (T) and reference (R) orally inhaled drug products (OIDPs). A chi-square ratio statistic (CSRS) was previously proposed for equivalence testing of CI profiles. However, it was reported that the CSRS could not consistently discriminate between equivalent and inequivalent CI profiles. The objective of the overall project was to develop a robust and sensitive methodology for assessing equivalence of APSD profiles of T and R OIDPs. We propose here a modified version of the CSRS (mCSRS) and evaluated systematically its behavior when T and R CI profiles were identical. Different scenarios comprising CI profiles with different number of deposition sites and shapes were generated by Monte-Carlo simulation. For each scenario, the mCSRS was applied to 20,000 independent sets of 30 T and 30 R CI profiles that were identical. Different metrics (including mean and median) of the distribution of 900 mCSRSs (30 T × 30 R) were then evaluated for their suitability as a test statistic (i.e., independent of the number of sites and shape of the CI profile) for APSD equivalence testing. The median of the distribution of 900 mCSRSs (MmCSRS) was one regardless of the number of sites and shape of the CI profile. Hence, the MmCSRS is a robust metric for CI profile equivalence testing when T and R CI profiles are identical and potentially useful for APSD equivalence testing.

  5. Neutral and Stable Equilibria of Genetic Systems and The Hardy-Weinberg Principle: Limitations of the Chi-Square Test and Advantages of Auto-Correlation Functions of Allele Frequencies

    Directory of Open Access Journals (Sweden)

    Francisco A Bosco

    2012-12-01

    Full Text Available Since the foundations of Population Genetics the notion of genetic equilibrium (in close analogy to Classical Mechanics has been associated with the Hardy-Weinberg (HW Principle and the identification of equilibrium is currently assumed by stating that the HW axioms are valid if appropriate values of Chi-Square (p<0.05 are observed in experiments. Here we show by numerical experiments with the genetic system of one locus/two alleles that considering large ensembles of populations the Chi-Square test is not decisive and may lead to false negatives in random mating populations and false positives in nonrandom mating populations. This result confirms the logical statement that statistical tests cannot be used to deduce if the genetic population is under the HW conditions. Furthermore, we show that under the HW conditions populations of any size evolve in time according to what can be identified as neutral dynamics to which the very notion of equilibrium is unattainable for any practical purpose. Therefore, under the HW conditions the identification of equilibrium properties needs a different approach and the use of more appropriate concepts. We also show that by relaxing the condition of random mating the dynamics acquires all the characteristics of asymptotic stable equilibrium. As a consequence our results show that the question of equilibrium in genetic systems should be approached in close analogy to non-equilibrium statistical physics and its observability should be focused on dynamical quantities like the typical decay properties of the allelic auto correlation function in time. In this perspective one should abandon the classical notion of genetic equilibrium and its relation to the HW proportions and open investigations in the direction of searching for unifying general principles of population genetic transformations capable to take in consideration these systems in their full complexity.

    针对硬阈值函数不连续导致视觉失真和软阈值函数存在恒定重构偏差的问题,依据噪声的曲波系数分布特性以及理想阈值函数特性,提出了基于卡方累积分布函数的新阈值函数。为了克服阈值去噪法固有的环绕效应和难以兼顾细节保持与去噪效果的性能缺陷,将偏微分方程去噪图像中包含的有益信息融合进新阈值函数去噪图像中,提出了新去噪方法。理论分析和仿真结果一致表明,较软、硬阈值去噪法,文中采用卡方累积分布函数和偏微分方程改进的曲波阈值去噪方法,可以有效地改善去噪效果和视觉质量。%To circumvent the visual distortion due to the discontinuity of the hard threshold function and the constant reconstruction deviation caused by the soft thresholding function,this paper presents a novel thresholding function based on the Chi-Square cumulative distribution function according to the distribution characteristics of curvelet coefficients of the noise and the ideal properties thehigh effective curvelet threshold functions should have.Further,in order to eliminate the surrounding effect inherent in curvelet threshold denoising methods and achieve a better balance between detail conservation and noise reduction, useful information involved in a denoised image produced by the partial differential equation denoising method is fused with that by the novel curvelet threshold function into the proposed denoising method. Theoretical analysis and simulation results show that the proposed denoiding method outper forms the soft and hard threshold denoising methods in terms of the denoising effect and visual quality.

    There exists a need for innovative thinking to identify new clinical placement opportunities for nursing students. Recovery-based clinical placements for mental health nurse students remain unique and require investigation. To examine the learning experience of Bachelor of Nursing students who undertook an innovative mental health clinical placement known as Recovery Camp. This study incorporated qualitative analysis of written reflections. Using Braun and Clarke's (2006) six phases of thematic analysis the corpus of student reflections were reviewed by three members of the research team independent to each other. Four themes emerged. The theme of Pre-placement Expectations incorporates participant foci on pre-conceptions of Recovery Camp. The theme of Student Learning incorporates the ways in which participants recognised the experience of Recovery Camp influenced learning. Reflections themed under the title Placement Setting include discussion of the Recovery Camp as a clinical placement. The theme of Future Practice incorporates students' reflections on how they plan to practice as nurses as a result the learning experiences of Recovery Camp. An immersive clinical placement such as Recovery Camp can influence students' perceptions of people with mental illness, have a positive impact on student learning and influence students' decisions about future practice. The learning experience of nursing students whom attend unique, recovery-orientated clinical placements can be both positive and educative. Copyright © 2016 Elsevier Ltd. All rights reserved.

    To determine perceptions of acceptable conducts amongst under and postgraduate optometry students and to compare them with students from other disciplines. Students (under/postgraduate) of optometry (n=156) and other courses (n=54) from University of Minho participated in a voluntary online questionnaire about perception of conducts, classifying as acceptable or unacceptable 15 academic or professional scenarios. 210 questionnaires were analyzed. Differences in perceptions were found between optometry under and postgraduates in scenario 5, Chi-square(2,156)=4.3, p=0.038, and scenario 7, Chi-square(2,156)=7.0, p=0.008 (both with cheating more acceptable for postgrads). Differences between under and postgraduates from other courses were found in scenario 9 (taking supplies from classroom more acceptable for undergrads), Chi-square(1,54)=5.0, p=0.025, and scenario 14 (forging a signature more acceptable for postgrads), Chi-square(1,54)=3.9, p=0.046. Differences between optometry and other courses undergraduates were observed in scenario 2 (plagiarism more acceptable for optometry undergrads), Chi-square(1,154)=8.3, p=0.004 and scenario 9 (taking supplies from classroom more acceptable for other undergrads), chi-square(1,54)=7.8, p=0.005. Differences between optometry and other courses postgraduates were observed in scenario 7, Chi-square(1,56)=5.8, p=0.016, scenario 10 (both with cheating more acceptable for optometry postgrads), chi-square(1,54)=8.1, p=0.004 and scenario 14 (forging a signature more acceptable for other postgrads), Chi-square(1,54)=6.1, p=0.026. Academic misconducts were mainly considered more acceptable than professional misconducts. Our results show that perceptions of acceptable conducts amongst optometry students are not very different from other students, and, against our initial prediction, do not show a general change in misconduct perception when students become more mature. Universities should pay more attention to this problem and take

  16. Why Learning Common Fractions Is Uncommonly Difficult: Unique Challenges Faced by Students With Mathematical Disabilities.

    2016-07-18

    In this commentary, I examine some of the distinctive, foundational difficulties in learning fractions and other types of rational numbers encountered by students with a mathematical learning disability and how these differ from the struggles experienced by students classified as low achieving in math. I discuss evidence indicating that students with math disabilities exhibit a significant delay or deficit in the numerical transcoding of decimal fractions, and I further maintain that they may face unique challenges in developing the ability to effectively translate between different types of fractions and other rational number notational formats-what I call conceptual transcoding I also argue that characterizing this level of comprehensive understanding of rational numbers as rational number sense is irrational, as it misrepresents this flexible and adaptive collection of skills as a biologically based percept rather than a convergence of higher-order competencies that require intensive, formal instruction.

    2011-01-01

    The density matrix in quantum mechanics parameterizes the statistical properties of the system under observation, just like a classical probability distribution does for classical systems. The expectation value of observables cannot be measured directly, it can only be approximated by applying classical statistical methods to the frequencies by which certain measurement outcomes (clicks) are obtained. In this paper, we make a detailed study of the statistical fluctuations obtained during an experiment in which a hypothesis is tested, i.e. the hypothesis that a certain setup produces a given quantum state. Although the classical and quantum problem are very much related to each other, the quantum problem is much richer due to the additional optimization over the measurement basis. Just as in the case of classical hypothesis testing, the confidence in quantum hypothesis testing scales exponentially in the number of copies. In this paper, we will argue 1) that the physically relevant data of quantum experiments ...

    1999-01-01

    Students were overwhelmingly positive when given the opportunity to evaluate the pilot project and the model of pediatric community health nursing. According to the students, the strong points of the model were the orientation before the community experience, the presence of faculty of the community, the ability to contact faculty when needed, and the postclinical conference. The students' comments confirmed the faculty's belief that a clinical experience in community health nursing must place more emphasis on the specialty of community health nursing to be meaningful for students. To do the of job of educating tomorrow's nurses, ADN faculty should develop new strategies for teaching the pediatric clinical component of community health nursing. Clearly, hospitals are no longer the exclusive sites where students learn about patient and family needs and nursing care delivery. Community-based and community-focused experiences will continue to be required so that nursing students are prepared to practice in a dynamic and changing healthcare environment.

    2014-06-15

    For 28 years, the Deep River Science Academy (DRSA) has been offering high school students the opportunity to engage in the excitement and challenge of professional scientific research to help nurture their passion for science and to provide them with the experience and the knowledge to make informed decisions regarding possible future careers in the fields of science, technology, engineering, and mathematics (STEM). The venue for the DRSA program has been a six-week summer science camp where students, working in pairs under the guidance of a university undergraduate tutor, contribute directly to an on-going research program under the supervision of a professional scientist or engineer. This concept has been expanded in recent years to reach students in classrooms year round by engaging students via the internet over a 12-week term in a series of interactive teaching sessions based on an on-going research project. Although the research projects for the summer program are offered primarily from the laboratories of Atomic Energy of Canada Limited at its Chalk River Laboratories site, projects for the year-round program can be based, in principle, in laboratories at universities and other research institutes located anywhere in Canada. This paper will describe the program in more detail using examples illustrating how the students become engaged in the research and the sorts of contributions they have been able to make over the years. The impact of the program on the students and the degree to which the DRSA has been able to meet its objective of encouraging students to choose careers in the fields of STEM and equipping them with the skills and experience to be successful will be assessed based on feedback from the students themselves. Finally, we will examine the program in the context of how well it helps to address the challenges faced by educators today in meeting the demands of students in a world where the internet provides instant access to information.

    To assess the interactive experience of first year medical students attending the leadership and management course hosted by a British Army Reserve Field Hospital developed in partnership with Liverpool University. 244 students submitted a 1000-word structured reflective learning assignment about their reaction to, learning from and any behaviour and attitude changes as a result of, the training. The assignments were thematically analysed to identify how aspects of the training had impacted upon the students' understanding of leadership and teamwork. Their comments relating to the army were analysed to gain insight into their views and experience of the training. Students were surprised at how enjoyable and useful they found the course. Initially they expressed scepticism about what they could learn in an army-based environment. However, the training, particularly command and planning tasks, helped them appreciate and understand the different skills individuals can bring to a team environment, and the importance of everyone contributing. While some students were challenged by aspects of the course, with support and encouragement from team-mates and the army personnel, they learned they could achieve more together. Teaching leadership and management skills to medical students is a challenge which can be effectively addressed by adapting and developing army training resources. Students overcame initial scepticism about participating, and learned a lot about themselves and each other. In addition, the army developed a better understanding of the doctors of the future. The expertise of the army in delivering this training was crucial to its success as the medical school could not have provided this experience unsupported.

    Full Text Available This study describes the implementation and effectiveness of small-group active engagement (GAE exercises in an introductory biology course (BSCI207 taught in a large auditorium setting. BSCI207 (Principles of Biology III—Organismal Biology is the third introductory core course for Biological Sciences majors. In fall 2014, the instructors redesigned one section to include GAE activities to supplement lecture content. One section (n = 198 employed three lectures per week. The other section (n = 136 replaced one lecture per week with a GAE class. We explored the benefits and challenges associated with implementing GAE exercises and their relative effectiveness for unique student groups (e.g., minority students, high- and low-grade point average [GPA] students. Our findings show that undergraduates in the GAE class exhibited greater improvement in learning outcomes than undergraduates in the traditional class. Findings also indicate that high-achieving students experienced the greatest benefit from GAE activities. Some at-risk student groups (e.g., two-year transfer students showed comparably low learning gains in the course, despite the additional support that may have been afforded by active learning. Collectively, these findings provide valuable feedback that may assist other instructors who wish to revise their courses and recommendations for institutions regarding prerequisite coursework approval policies.

    Arab-Muslims have extremely religious-centered and restrictive cultural practices. Living in a foreign country where Islam is a minority religion and culture is categorically different entails a great deal of adjustment. This study explored how Arab-Muslim International Students live and cope in a non-Arab, non-Muslim country. The authors used phenomenological approach with Colaizzi's method of analysis to (1) explore the lived experience of the Arab students' academic and social life and (2) come up with recommendations that can be supported by universities in Philippines and other countries with Arab students. Emergent themes include Hybrid vision and empowerment from education beyond borders "Tatallo at wa kudurat," Stigma in the Arab world "Hallah," Islam as way of life "Al Islam: Manhaj Hayyat," and Future of the Arab-Muslim students "Wahaa." The major concepts that emerged from the lived experience of these students focused on the practical reasons for quality education, challenges along the way, culture shock, the stigma, and misconceptions about Arabs and Muslims. They experienced discrimination, the impact of stereotyping and misconceptions about the Arab-Muslims. Their tenacity of the Islam faith has become a coping mechanism and kept them enormously strong. They also strived to show the real meaning of being Muslim, and finally, looking forward to how they can become the oasis in the desert. The Arab-Muslim International Students experience difficult adjustments in a foreign country to acquire high quality education, while holding on to their Islam faith and keeping their culture intact.

    Full Text Available Background Cultural awareness education is mandatory for medical programs, with particular emphasis on Aboriginal and Torres Strait Islander health. However, there is limited evidence to measure the impact of such education has on medical students. Aims This paper presents the development and delivery of a cultural immersion activity for first year undergraduate medical students. Additionally we explore how this type of activity may improve attitudes, comprehension and perceived competence relating to working with and understanding people of different cultures. Methods A pre- and post-survey design was utilised in connection with a cultural immersion activity. First year medical students (N=284, responses 196, 69 per cent from three cohorts (2012–2014 inclusive voluntarily completed a cultural awareness questionnaire, which contained items that related to perceptions, personal characteristics and educational competence. The main outcome measures were changes in perceived cultural knowledge, awareness, beliefs and attitudes. Data were analysed using principal component analysis and obtained means comparison. Results Principal component analysis revealed five dimensions for pre-post comparison: Knowledge Acquisition, Perceptions of Role Modelling, Internal Beliefs and Reflections, Personality Variables and Institutional Influences. Non-parametric means comparison showed increased ratings for knowledge acquisition and institutional influences (p<0.001, whilst a decline was noted for the personality variables (p<0.05. Conclusion Cultural immersion has great potential to elicit positive shifts in attitudinal and knowledge related aspects of cultural awareness at early stages in medical curricula. Negative directions also suggest that students question their beliefs and behaviours relating to cultural knowledge.

    Full Text Available Production processes are monitored by control charts since their inception by Shewhart (1924. This surveillance is useful in improving the production process due to increased stabilization of the process, and consequently standardization of the output. Control charts keep track of a few key quality characteristics of the outcome of the production process. This is done by means of univariate or multivariate charts. Small improvements in control chart methodology can have significant economic impact in the production process. In this investigation, we propose the monitoring of a single variable by means of a variable parameter non-central chi-square control chart. The design of the chart is accomplished by means of optimizing a cost function. We use here a simulated annealing optimization tool, due to the difficulty of classical gradient based optimization techniques to handle the optimization of the cost function. The results show some of the drawbacks of using this model.Processos de produção são monitorados por gráficos de controle desde a sua introdução por Shewhart (1924. Este monitoramento é útil na melhoria do processo de produção devido à crescente estabilização do processo, e consequentemente, padronização do produto.

  19. Level of self-esteem and contingencies of self-worth: unique effects on academic, social, and financial problems in college students.

    Science.gov (United States)

    Crocker, Jennifer; Luhtanen, Riia K

    2003-06-01

    The unique effects of level of self-esteem and contingencies of self-worth assessed prior to college on academic, social, and financial problems experienced during the freshman year were examined in a longitudinal study of 642 college students. Low self-esteem predicted social problems, even controlling for demographic and personality variables (neuroticism, agreeableness, and social desirability), but did not predict academic or financial problems with other variables controlled. Academic competence contingency predicted academic and financial problems and appearance contingency predicted financial problems, even after controlling for relevant personality variables. We conclude that contingencies of self-worth uniquely contribute to academic and financial difficulties experienced by college freshmen beyond level of self-esteem and other personality variables. Low self-esteem, on the other hand, appears to uniquely contribute to later social difficulties.

    Full Text Available Abstract Background Processing personal data for research purposes and the requirement of anonymity has been the subject of recent debate. We aimed to determine the proportion of individuals who present to emergency departments with non-fatal suicidal behavior where an NHS number has been successfully traced and to investigate the characteristics of patients associated with non-capture. Method This was a descriptive study of people attending after self-harm using allocation of NHS numbers as main outcome measurement. Data from the Multicentre Monitoring of Self-Harm Project from 3 centres in England were used to identify consecutive patients (N = 3000 who were treated in six emergency departments in Oxford, Manchester and Leeds in 2004 and 2005 following self-harm. Results NHS number was available between 55–73% of individuals across centres. Characteristics associated with non-recording of NHS number in more than one centre included those from ethnic minority groups (Oxford: chi-squared statistic = 13.6, df = 3, p = 0.004; Manchester: chi-squared statistic = 13.6, df = 3, p ≤0.001 and the homeless or living in a hostel or other institution (Oxford: chi-squared statistic = 40.9, df = 7, p = Conclusion Basing research studies on NHS number as the unique identifier, as suggested by the Data Protection Act 1998 and the Patient Information Advisory Group, would exclude some of the most vulnerable groups for further self-harm or suicide. This bias may also affect other research registers.

    The phenomenon of deliberate self-harm (DSH) among college students has received increased attention in recent decades. Adopting a psychosocial perspective, this study aims to describe self-reported DSH among Chinese medical college students, assess respective associations between uncertainty stress and social capital with DSH, and explore the mechanism linking these three phenomena. A cross-sectional survey employing multi-stage, sampling was conducted. 4446 undergraduate students were recruited from 22 participating Chinese medical universities. Perceived stress from uncertainty and social capital were assessed among the students. The Chi-square test and multiple logistic regression models assessed correlates of DSH. Relationship among social capital, uncertainty stress, and DSH were examined by means of Structural Equation Modeling. The prevalence of DSH in the past 12 months among Chinese students was 9.6%. The most common types of physical DSH reported were scratching, cutting, and pinching. Age (χ(2)=26.63, pstress is a unique correlate of DSH, and shows a stronger association than do three certainty stressors. Social capital is also a strong correlate of DSH, especially cognitive social capital. Moreover, social capital may be indirectly associated with DSH through impacting uncertainty stress. This study was a cross-sectional and thus could not evaluate causal relationships. We recommend that a DSH intervention study should target uncertainty stress management and social capital accumulation. This study provides scientific evidence and theoretical foundation for future DSH interventions, with a view to enhancing the mental health of medical college students. Copyright © 2016 Elsevier B.V.

    2013-01-01

    This research examined how motivation (perceived control, intrinsic motivation, and extrinsic motivation), cognitive learning strategies (deep and surface strategies), and intelligence jointly predict long-term growth in students' mathematics achievement over 5 years. Using longitudinal data from six annual waves (Grades 5 through 10; Mage  = 11.7 years at baseline; N = 3,530), latent growth curve modeling was employed to analyze growth in achievement. Results showed that the initial level of achievement was strongly related to intelligence, with motivation and cognitive strategies explaining additional variance. In contrast, intelligence had no relation with the growth of achievement over years, whereas motivation and learning strategies were predictors of growth. These findings highlight the importance of motivation and learning strategies in facilitating adolescents' development of mathematical competencies.

    The Kepler spacecraft observes a host of target stars to detect transiting planets. Requiring a 7.1 sigma detection in twelve quarters of data yields over 100,000 detections, many of which are false alarms. After a second cut is made on a robust detection statistic, some 50,000 or more targets still remain. These false alarms waste resources as they propagate through the remainder of the software pipeline and so a method to discriminate against them is crucial in maintaining the desired sensi...

  18. A DoS/DDoS Attack Detection System Using Chi-Square Statistic Approach

    Directory of Open Access Journals (Sweden)

    Fang-Yie Leu

    2010-04-01

    Full Text Available Nowadays, users can easily access and download network attack tools, which often provide friendly interfaces and easily operated features, from the Internet. Therefore, even a naive hacker can also launch a large scale DoS or DDoS attack to prevent a system, i.e., the victim, from providing Internet services. In this paper, we propose an agent based intrusion detection architecture, which is a distributed detection system, to detect DoS/DDoS attacks by invoking a statistic approach that compares source IP addresses' normal and current packet statistics to discriminate whether there is a DoS/DDoS attack. It first collects all resource IPs' packet statistics so as to create their normal packet distribution. Once some IPs' current packet distribution suddenly changes, very often it is an attack. Experimental results show that this approach can effectively detect DoS/DDoS attacks.

    Peak fitting is an essential part of X-ray photoelectron spectroscopy (XPS) narrow scan analysis, and the Literature contains both good and bad examples of peak fitting. A common cause of poor peak fitting is the inclusion of too many fit parameters, often without a sound chemical and/or physical basis for them, and/or the failure to reasonably constrain them. Under these conditions, fit parameters are often correlated, and therefore lacking in statistical meaning. Here we introduce the uniqueness plot as a simple graphical tool for identifying bad peak fits in XPS, i.e., fit parameter correlation. These plots are widely used in spectroscopic ellipsometry. We illustrate uniqueness plots with two data sets: a C 1s narrow scan from ozone-treated carbon nanotube forests and an Si 2p narrow scan from an air-oxidized silicon wafer. For each fit, we consider different numbers of parameters and constraints on them. As expected, the uniqueness plots are parabolic when fewer fit parameters and/or more constraints are applied. However, they fan out and eventually become horizontal lines as more unconstrained parameters are included in the fits. Uniqueness plots are generated by plotting the chi squared (χ2) value for a fit vs. a systematically varied value of a parameter in the fit. The Abbe criterion is also considered as a figure of merit for uniqueness plots in the Supporting Information. We recommend that uniqueness plots be used by XPS practitioners for identifying inappropriate peak fits.

    A study to evaluate the relationship between the spiritual intelligence and adjustment among the college students was conducted on a sample of 250 students in six various colleges of Tuticorin district, Tamil Nadu, India. Gender, religion, community, major subject, educational qualification of father and mother, student locality, college type, father and mother's occupation and monthly family income (n = 11 variables) were chosen for the study. Test of significance for spiritual intelligence and adjustment was studied and found them nonsignificant except student locality, found to be significant. Two valid and reliable instruments were used to assess student's spiritual intelligence and adjustment. Correlation and Chi-square analysis using structural equation model were used to analyze these data. Correlation analysis showed significant relationship between the variables among the college students (n = 250). Chi-square analysis of association between adjustments of college students showed that most variables are nonsignificant unlike father's educational qualification and mother's occupation. The results disclosed the significant positive relationship with spiritual intelligence and adjustment among adolescents.

    Full Text Available This study examined whether student gender and the type of student misbehavior affected the classroom management techniques of pre-service teachers. Participants were pre-service teachers who interacted with avatar students controlled by an actor in a mixed-reality environment. Avatar students’ behaviors were systematically coded along with their gender. Pre-service teachers’ responses were organized into four categories: coercion, retreatism, normative, and remunerative. Pre-service teachers’ use of proximity and tone of voice were also recorded. Data were analyzed using chi-square and ANOVA tests. Significant differences in pre-service teacher responses were found for type of avatar student misbehavior but not avatar student gender. Results and implications for future research are discussed.

    Full Text Available Research studies examining the mental health of transgender individuals often focus on depression, anxiety, and suicidal ideation through the use of clinic samples. However, little is known about the emerging adult (18–26 years old transgender population and their mental health. The current study seeks to fill that gap by using a national dataset of college students (N = 547,727 to examine how transgender college students (n = 1143 differ from their cisgender peers regarding 12 different mental health conditions. Chi-square and regression analyses were conducted. Results demonstrate that transgender students have approximately twice the risk for most mental health conditions compared to female students. A notable exception is schizophrenia, in which transgender individuals have about seven times the risk compared to females. While these were significant findings, regression analyses indicate that being non-heterosexual is a greater predictor for mental health concerns. Implications for mental health practitioners at colleges and universities are discussed.

    Dental caries, still one of the most common diseases affecting people around the world, has a multifactorial nature encompassing necessary (biofilm accumulation), determinant (exposure to sugars and fluoride) and modulating factors (biological and social). The concepts about caries learned at dental schools may directly influence the conduct of the future dentists regarding the control and treatment of this disease. The aim of this study was to determine the concept that students at the Piracicaba Dental School, University of Campinas, Brazil, have about dental caries. In this cross-sectional descriptive study, 274 students answered the discursive question "Conceptualize dental caries". Students' answers were analyzed by a content analysis technique that allowed the creation of response categories and classification of the concepts in categories. Frequencies were expressed as absolute numbers and percentages. Differences between the responses according to the students' class years were tested by the chi-square test. Differences with pcaries.

    Urban expansion is a spatial phenomenon that reflects the increased level of importance of metropolises. The remotely sensed data and GIS have been widely used to study and analyze the process of urban expansions and their patterns. The capital of Libya (Tripoli) was selected to perform this study and to examine its urban growth patterns. Four satellite imageries of the study area in different dates (1984, 1996, 2002 and 2010) were used to conduct this research. The main goal of this work is identification and analyzes the urban sprawl of Tripoli metropolitan area. Urban expansion intensity index (UEII) and degree of freedom test were used to analyze and assess urban expansions in the area of study. The results show that Tripoli has sprawled urban expansion patterns; high urban expansion intensity index; and its urban development had high degree of freedom according to its urban expansion history during the time period (1984-2010). However, the novel proposed hypothesis used for zones division resulted in very good insight understanding of urban expansion direction and the effect of the distance from central business of district (CBD).

    Humphrey, Philip J; Buote, David A

    2008-01-01

    We demonstrate that two approximations to the chi^2 statistic as popularly employed by observational astronomers for fitting Poisson-distributed data can give rise to intrinsically biased model parameter estimates, even in the high counts regime, unless care is taken over the parameterization of the problem. For a small number of problems, previous studies have shown that the fractional bias introduced by these approximations is often small when the counts are high. However, we show that for a broad class of problem, unless the number of data bins is far smaller than \\sqrt{N_c}, where N_c is the total number of counts in the dataset, the bias will still likely be comparable to, or even exceed, the statistical error. Conversely, we find that fits using Cash's C-statistic give comparatively unbiased parameter estimates when the counts are high. Taking into account their well-known problems in the low count regime, we conclude that these approximate chi^2 methods should not routinely be used for fitting an arbit...

    To determine the exposure of medical students to the marketing activities of the pharmaceutical industry, and identify their opinions and attitudes, and also the possible effects this exposure on their training and future professional practice. Descriptive cross-sectional. University of Zaragoza Faculty of Medicine. Third, fourth, fifth and sixth year medical students. The information was obtained using a previously adapted, self-report questionnaire on the exposure, attitudes and perceived suitability of drug marketing activities. Percentages were calculated for the categorical variables, applying the chi squared test for the comparison between the groups. A logistic regression was performed to determine the factors associated with their attitudes towards these activities. A total of 369 questionnaires were returned (93% of those attending classes). The exposure to marketing activities is high, particularly in the clinical stage (78.6% said to have received a gift non-educational gift). The students recognised the possible biases and repercussions in professional practice, although with ambiguity and contradictions. The most accepted activities are those associated with training, and the most critical attitudes appear in the clinical stage, particularly in the sixth year. Exposure to drug marketing by medical students and its possible training and professional effects is frequent and significant. The training environment is particularly open to promotional activities. The differences observed in the later years suggest the need for a specific curriculum subject and development of reflective attitudes by the students themselves.

    Full Text Available Introduction: Student counseling and supervision play an important role to overcome learning problems and to achieve educational goals. The present study is intended to investigate viewpoints of students regarding educational guidance and advice studying at Babol University of Medical Sciences. Methods: In this descriptive cross-sectional survey, viewpoints of 480 students were collected by a questionnaire. The validity and reliability of the questionnaire had been approved before. Data were analyzed using SPSS version 17 software. Chi- square and ANOVA tests were administered. Results: 61.2% of all participants were female and 38.8% were males with mean age of 21.3±4.0. 37.2% of these students lacked sufficient knowledge and information on how to request from their advisors for help and guidance. Half of students (50.3% reported attendance of advisors and holding routine consultation is inappropriate. Advisors made more educational files for females compare to males (P=0.001. No difference observed regarding educational disciplines of the advisors regarding students were dissatisfied with help and guidance received from paramedics and dentistry students in most fields (87.3% and 81.5% respectively. Conclusion: It seems that either student has no sufficient information about tasks of advisors and/or advisors may not do their tasks properly. It is recommended the students to be acquainted with advisors’ tasks upon their entrance into the university. Training classes for new academics would be helpful.

    Colleges are rape-prone cultures with high rates of sexual victimization. Fraternities' and sororities' relationships with sexual assault are consistent themes in literature focusing on sexual violence among college students. Previous research suggests that fraternity men are more likely to endorse rape-supportive attitudes compared with non-Greek men or sorority women. The present study examines rape-supportive attitudes as well as rape and sexual assault victimization in college students with a focus on gender and Greek-life (i.e., involvement in fraternities or sororities) status variables. College students (N = 1,002) completed a survey including the Token Resistance to Sex Scale (TRSS), Illinois Rape Myth Acceptance Scale-Short Form (IRMA-S), and items related to past experiences of nonconsensual sex. Two regression models tested predictors of token resistance and rape myth acceptance. Chi-square analyses tested between-group differences of experiencing rape and sexual assault. Gender (p rape myth acceptance than any other group. Chi-square analyses indicate women more frequently report experiences of rape (χ(2) = 25.57, df = 1, p rape myth acceptance and token resistance by Greeks, who influence college party culture, could be contributing to a culture conducive to rape. Findings demonstrate a continued need for interventions focused on shifting sociocultural dynamics (e.g., traditional roles and sexual scripting) on college campuses.

    Full Text Available Abstract Background There are limited data on the prevalence rate of Metabolic Syndrome (MetS among college students attending any Historically Black College and University (HBCU, which are mostly attended by young African Americans (AA. We report the prevalence and gender differences in the components of MetS in a sample population from an HBCU campus. Methods Three hundred and seventy six (218 females and 158 males first year college students (average age 19.8 years, attending Kentucky State University, Frankfort with no prior diagnosis of illness participated in the cross sectional study. Anthropometric screenings included measurement of height, weight, waist circumference and body mass index (BMI. The clinical screenings included measurement of blood pressure and determination of fasting lipid and glucose concentrations. The National Cholesterol Education Program’s Adult Treatment Panel III (NCEP ATP III and International Diabetes Federation (IDF definitions for MetS were applied. Statistics: Analysis of variance (ANOVA scores on the Means procedure were used to examine differences between genders for all anthropometric, clinical and biochemical parameters. Fisher’s exact chi-square tests were used to analyze the prevalence of MetS criteria per gender, the number of MetS criteria per BMI category and the prevalence of MetS criteria. Significance was set at p ≤ 0.05 for all tests. Results Prevalence rates for MetS criteria varied depending on the definition used. According to the NCEP ATP definition, 31.4% of the sample population had at least 1 criterion for MetS, while 20.7% had 2 criteria. When IDF definition was applied, 21.3% sample population had 1 criterion and 17.5% had at least two criteria. Prevalence was highest for low levels of high-density lipoprotein cholesterol (37.3% and elevated fasting glucose (22.1%. On the basis of the NCEP ATP and IDF definitions, overall prevalence of MetS in the total sample was 12%, and 9

    The study is based on a secondary analysis of data from the 3rd year of the Scientific Literacy Project (SLP), a federally funded research project that examines how kindergarten students learn science in inquiry settings (Mantzicopoulos, Patrick, & Samarapungavan, 2005). Videotapes of classroom lessons implemented as part of the Year 3 intervention were analyzed to identify kindergarten students' patterns of cognitive engagement during inquiry-based science learning, as well as to identify patterns of teacher discourse that promoted students' cognitive engagement. The data for the current study were drawn from videotapes and transcriptions of classroom discourse in 3 intervention classrooms that participated in the SLP. Three teachers and 55 kindergarten students participated in the study. Twelve categories of kindergarten students' cognitive engagement and eleven categories of teacher discourse were identified. The initial 12 student and 11 teacher discourse categories were further grouped into two superordinate categories (Higher Order and Basic) respectively. Chi Square analyses indicated that there was a statistically significant association between student and teacher superordinate discourse (alpha = .05). MANOVA analyses indicated that there was no significant difference on overall rates of kindergarten students' cognitive engagement by class (alpha = .05).

    Berry, Chelsia

    The purpose of this study was to determine if participation in science dual enrollment courses influenced African American high school students' post-secondary aspirations that will lead to college attendance. The investigation examined the relationship between African American students' learning experiences and how their self-efficacy and outcome expectations impact their goal setting. The goal was to determine the impact of the following variables on African American students' plan to pursue a bachelor's or advanced degree: (a) STEM exposure, (b) Algebra 1 achievement, (c) level of science class, and (d) receiving science college credit for dual enrollment course. The social cognitive career theory framed this body of research to explore how career and academic interests mature, are developed, and are translated into action. Science dual enrollment participation is a strategy for addressing the lack of African American presence in the STEM fields. The causal comparative ex post facto research design was used in this quantitative study. The researcher performed the Kruskal-Wallis non-parametric analysis of variance and Pearson's chi-square tests to analyze secondary data from the High School Longitudinal Study first follow-up student questionnaire. The results indicate that STEM exposure and early success in Algebra 1 have a statistically significant impact on African American students' ambition to pursue a bachelor's or advanced degree. According to the Pearson's chi-square and independent sample Kruskal-Wallis analyses, level of students' science class and receiving college credit for dual enrollment do not significantly influence African American students' postsecondary aspirations.

    This paper describes the use of the COMPUSTAT database in teaching an introductory course in business finance at a large College of Business Administration. To understand students' attitudes towards this innovative method of instruction in business finance, a simple one-page questionnaire of 10 attitudinal statements was used. Responses of 148 students, analyzed by chi square, indicated students were unanimous in their opinion that the World Wide Web greatly paved the way in data retrieval from the COMPUSTAT database. They further reported that this interface facilitated analyses for the course. Also their understanding of finance was enhanced, and they were motivated to learn more. They seem to be highly in favor of using COMPUSTAT database in the introductory courses in business finance and expressed this view by suggesting that this financial database should be made an integral part of teaching other courses in finance.

    In the past, distance education was used as a method to meet the educational needs of citizens with limited options to attend an institution of higher education. Nowadays, it has become irreplaceable in higher education thanks to developments in instructional technology. But the question of why students choose distance education is still important. The purpose of this study was to determine Turkish students' reasons for choosing distance education and to investigate how these reasons differ depending on their financial circumstances. The author used a Chi squared Automatic Interaction Detector (CHAID) analysis to determine 18,856 Turkish students' reasons for choosing distance education. Results of the research revealed that Turkish students chose distance education not because of geographical limitations, family-related problems or economic difficulties, but for such reasons as already being engaged in their profession, increasing their knowledge, and seeking promotion to a better position.

    Simultaneous polysubstance use (SPU) is a common phenomenon, yet little is known about how various substances are used with one another. In the present study 149 drug-using university students completed structured interviews about their use of various substances. For each substance ever used, participants provided details about the type, order and amount of all substances co-administered during its most recent administration. Alcohol, tobacco and cannabis were frequently co-administered with each other and with all other substances. Chi-squared tests revealed that when alcohol was used in combination with any of cannabis, psilocybin, MDMA, cocaine, amphetamine, methylphenidate (ps alcohol was used with cocaine (p alcohol, cannabis, psilocybin, MDMA, cocaine, amphetamine (ps < 0.001), LSD (p < 0.01) or methylphenidate (p < 0.05). Results suggest that many substances are routinely used in a SPU context and that the pattern in which a substance is used may be related to other substances co-administered.

    To describe levels of burnout and impostor syndrome (IS) in medical students, and to recognize demographic differences in those experiencing burnout and IS. Anonymous survey administered online in 2014 that included demographic data, the Maslach Burnout Inventory and an IS screening questionnaire. Main outcome measures were level of burnout, and presence or absence of imposter syndrome. The presence of IS and burnout components were analyzed across age, gender, race, year of training, intention to pursue fellowship training, and greater than one year of work experience outside of medicine using chi-squared tests. The association between burnout and IS was also compared using chi-squared tests. One hundred and thirty-eight students completed the questionnaire. Female gender was significantly associated with IS (χ(2)(3)=10.6, p=0.004) with more than double the percentage of females displaying IS than their male counterparts (49.4% of females versus 23.7% of males). IS was significantly associated with the burnout components of exhaustion (χ(2) (2)=5.9, p=0.045), cynicism (χ(2)(2)=9.4, p=0.004), emotional exhaustion (χ(2)(2)=8.0, p=0.018), and depersonalization (χ(2) (2)=10.3, p=0.006). The fourth year of medical school was significantly associated with IS (χ(2)(3)=10.5, p=0.015). Almost a quarter of male medical students and nearly half of female students experience IS and IS was found to be significantly associated with burnout indices. Given the high psychological morbidity of these conditions, this association cannot be ignored. It behooves us to reconsider facets of medical education (i.e. shame-based learning and overall teaching style) and optimize the medical learning environment.

    This study examined whether the 5-HTTLPR polymorphism in the SLC6A4 gene is associated with self-reported symptoms of depressed mood in first-year university students with a persistent pattern of short sleep. Students provided DNA samples and completed on-line sleep diaries and a mood scale during the first semester. A priori phenotypes for nocturnal sleep and mood scores were compared for the distribution of genotypes. Brown University, Providence, Rhode Island. A sample of 135 first-year students, 54 male, 71 Caucasian, mean age 18.1 (± 0.5) yr. None. Students completed on-line sleep diaries daily across the first term (21-64 days; mean = 51 days ± 11) and Center for Epidemiologic Studies-Depression (CES-D) mood scale after 8 wk. DNA was genotyped for the triallelic 5-HTTLPR polymorphism. Low-expressing S and L(G)polymorphisms were designated S', and high-expressing L(A) was designated L'. Phenotype groups were identified from a combination of CES-D (median split: high > 12; low students. FOUR PHENOTYPE GROUPS WERE COMPARED: 40 students with shorter TST/high CES-D; 34 with shorter TST/low CES-D; 29 with longer TST/high CES-D; 32 with longer TST/low CES-D. Female:male distribution did not vary across phenotype groups (chi-square = 1.39; df = 3; P = 0.71). S'S' participants (n = 23) were overrepresented in the shorter TST/high CES-D group (chi- square = 15.04; df = 6; P < 0.02). This association was sustained after removing participants with preexisting evidence of depressed mood (chi-square = 12.90; df = 6; P = 0.045). These data indicate that young adults who reported shorter nocturnal sleep and higher depressed mood are more likely than others to carry a variant of the SLC6A4 gene associated with low expression of the serotonin transporter.

The aim of this study was to investigate variables that influence student's performance in a retrospective sample including all undergraduate students who entered in a Brazilian dental school, in a 20-year period between 1984 and 2003 (n=1182). Demographic and educational variables were used to predict performance in the overall curriculum and course groups. Cluster analysis (K-means algorithm) categorized students into groups of higher, moderate or lower performance. Clusters of overall performance showed external validity, demonstrated by Chi-square test and ANOVA. Lower performance groups had the smallest number of students in overall performance and course groups clusters, ranging from 11.8% (clinical courses) to 19.2% (basic courses). Students' performance was more satisfactory in dental and clinical courses, rather than basic and non-clinical courses (pstudent's performance was predicted by lower time elapsed between completion of high school and dental school admission, female gender, better rank in admission test, class attendance rate and student workload hours in teaching, research and extension (R(2)=0.491). Findings give evidence about predictors of undergraduate students' performance and reinforce the need for curricular reformulation focused on with improvement of integration among courses.

    Introduction: The subject of chronic stress and ways of dealing with it are very broad. The aim of this study was to analyze stress and anxiety and their influence on suicidal thinking among medical students. Materials and Methods: The study was conducted in the years 2014 to 2015 in Poland, at the Medical University—Nicolaus Copernicus University, Collegium Medicum. The objective of this study was to assess chronic stress and suicidal thinking among students and how students cope with this huge problem. Descriptive statistics and chi-square analyses were conducted to detect differences. Results: Analyses showed that students’ life is full of stressors. Students toward the end of their education cope better with stress than students starting their university studies. Chronic stress has a strong impact on mental health and suicidal thinking among students. Conclusions: The results of the study confirmed that chronic stress and anxiety have a negative influence on mental health and also confirm a relation to suicidal thinking in medical students. Students cope with stress by listening to music, talking to relatives or people close to them, resting or engaging in sports, with cycling, running and swimming being the most common methods used to affect suicidal thinking.

    Brown, Jayna Nicole

    Although traditional college students are more prepared for college-level math based on college admissions tests, little data have been collected on nontraditional adult learners. The purpose of this study was to investigate relationships between math placement tests and community college students' success in math courses and persistence to degree or certificate completion. Guided by Tinto's theory of departure and student retention, the research questions addressed relationships and predictability of math Computer-adaptive Placement Assessment and Support System (COMPASS) test scores and students' performance in math courses, persistence in college, and degree completion. After conducting correlation and regression analyses, no significant relationships were identified between COMPASS Math test scores and students' performance (n = 234) in math courses, persistence in college, or degree completion. However, independent t test and chi-squared analyses of the achievements of college students who tested into Basic Math (n = 138) vs. Introduction to Algebra (n = 96) yielded statistically significant differences in persistence (p = .039), degree completion (p indicating students who tested into Introduction to Algebra were more successful and persisted more often to degree completion. In order to improve instructional methods for Basic Math courses, a 3-day professional development workshop was developed for math faculty focusing on current, best practices in remedial math instruction. Implications for social change include providing math faculty with the knowledge and skills to develop new instructional methods for remedial math courses. A change in instructional methods may improve community college students' math competencies and degree achievement.

    Full Text Available Introduction: The purpose of this study was to determine the associations and predictive values of Medical College Admission Test (MCAT component and composite scores prior to 2015 with U.S. Medical Licensure Exam (USMLE Step 1 and Step 2 Clinical Knowledge (CK scores, with a focus on whether students scoring low on the MCAT were particularly likely to continue to score low on the USMLE exams. Method: Multiple linear regression, correlation, and chi-square analyses were performed to determine the relationship between MCAT component and composite scores and USMLE Step 1 and Step 2 CK scores from five graduating classes (2011–2015 at the University of Minnesota Medical School (N=1,065. Results: The multiple linear regression analyses were both significant (p<0.001. The three MCAT component scores together explained 17.7% of the variance in Step 1 scores (p<0.001 and 12.0% of the variance in Step 2 CK scores (p<0.001. In the chi-square analyses, significant, albeit weak associations were observed between almost all MCAT component scores and USMLE scores (Cramer's V ranged from 0.05 to 0.24. Discussion: Each of the MCAT component scores was significantly associated with USMLE Step 1 and Step 2 CK scores, although the effect size was small. Being in the top or bottom scoring range of the MCAT exam was predictive of being in the top or bottom scoring range of the USMLE exams, although the strengths of the associations were weak to moderate. These results indicate that MCAT scores are predictive of student performance on the USMLE exams, but, given the small effect sizes, should be considered as part of the holistic view of the student.

    Full Text Available BACKGROUND: The use of psychoactive substances is one of the most important public health issues. Tobacco, alcohol and illicit drugs are among the top risk factors for ill-health defined by World Health Organisation. The risky behaviours acquired in teenage can be magnified or decreased during university when a person starts having more awareness about the importance of own wellness. This paper describes the results of the project "Sportello Salute Giovani" ("Youth Health Information Desk" with respect to risky behaviours in a large sample of Italian university students. MATERIALS AND METHODS: 18 questions of the survey "Sportello Salute Giovani" dealing with risky behaviors, the use of psychoactive substances such as tobacco, alcohol and illicit drugs were included. Absolute and relative frequencies were calculated. Besides, chi square test were used to test the differences in sex, age class and socio-economic status. RESULTS: About 24% of the interviewed students currently smokes. 89% and 42.2% respectively drinks at least rarely or weekly beer, wine or spirits. About 40% of students smoked at least a joint and about 2% used other drugs (mostly cocaine. CONCLUSION: The "Sportello Salute Giovani" survey suggests that the frequency of risky behaviours in Italian university students is not reassuring, although they should be aware about the negative consequences on their and others health because of their educational level.

    Introduction Head sense position is coordinated by sensory activity of the vestibular system, located in the inner ear. Children with sensorineural hearing loss may show changes in the vestibular system as a result of injury to the inner ear, which can alter the sense of head position in this population. Aim Analyze the head alignment in students with normal hearing and students with sensorineural hearing loss and compare the data between groups. Methods This prospective cross-sectional study examined the head alignment of 96 students, 48 with normal hearing and 48 with sensorineural hearing loss, aged between 7 and 18 years. The analysis of head alignment occurred through postural assessment performed according to the criteria proposed by Kendall et al. For data analysis we used the chi-square test or Fisher exact test. Results The students with hearing loss had a higher occurrence of changes in the alignment of the head than normally hearing students (p < 0.001). Forward head posture was the type of postural change observed most, occurring in greater proportion in children with hearing loss (p < 0.001), followed by the side slope head posture (p < 0.001). Conclusion Children with sensorineural hearing loss showed more changes in the head posture compared with children with normal hearing. PMID:25992037

    Mathematics is an essential and fundamental tool used by engineers to analyse and solve problems in their field. Due to this, most engineering education programs involve a concentration of study in mathematics courses whereby engineering students have to take mathematics courses such as numerical methods, differential equations and calculus in the first two years and continue to do so until the completion of the sequence. However, the students struggled and had difficulties in learning courses that require mathematical abilities. Hence, this study presents the factors that caused mathematics anxiety among engineering students using Abbreviated Mathematics Anxiety Rating Scale (AMARS) through 95 students of Universiti Teknikal Malaysia Melaka (UTeM). From 25 items in AMARS, principal component analysis (PCA) suggested that there are four mathematics anxiety factors, namely experiences of learning mathematics, cognitive skills, mathematics evaluation anxiety and students' perception on mathematics. Minitab 16 software was used to analyse the nonparametric statistics. Kruskal-Wallis Test indicated that there is a significant difference in the experience of learning mathematics and mathematics evaluation anxiety among races. The Chi-Square Test of Independence revealed that the experience of learning mathematics, cognitive skills and mathematics evaluation anxiety depend on the results of their SPM additional mathematics. Based on this study, it is recommended to address the anxiety problems among engineering students at the early stage of studying in the university. Thus, lecturers should play their part by ensuring a positive classroom environment which encourages students to study mathematics without fear.

    Breast and cervical cancers are the most common types of cancer in women worldwide. Previous studies in Asia have shown that related knowledge and awareness is low among female university students. The goal of this study was to assess breast and cervical cancer knowledge, practices, and awareness among female university students in Samsun,Turkey. This research was a cross-sectional survey of female university students using a self-administered. questionnaire to investigate participant awareness and knowledge of breast and cervical cancer. A total of 301 female university students participated. Descriptive statistics and chi square tests were used for data analysis. The mean age of the participants in this study was 22.0 ± 5.91 years. Regarding family history, 89.7 % of the students had no known familial history of breast cancer. Students (65.4%) had knowledge about breast self examination and 52.2 % of them had performed breast self examinationm while 55.1% of them had knowledge about prevention of cervical cancer. Although the results are preliminary, the study points to an insufficient knowledge of university students in Samsun about breast and cervical cancer.

    Full Text Available Patient safety is a new and challenging discipline in the Iranian health care industry. Among the challenges for patient safety improvement, education of medical and paramedical students is intimidating. The present study was designed to assess students' perceptions of patient safety, and their knowledge and attitudes to patient safety education. This cross-sectional analytical study was conducted in 2012 at Urmia University of Medical Sciences, West Azerbaijan province, Iran. 134 students studying medicine, nursing, and midwifery were recruited through census for the study. A questionnaire was used for collecting data, which were then analyzed through SPSS statistical software (version 16.0, using Chi-square test, Spearman correlation coefficient, F and LSD tests. A total of 121 questionnaires were completed, and 50% of the students demonstrated good knowledge about patient safety. The relationships between students' attitudes to patient safety and years of study, sex and course were significant (0.003, 0.001 and 0.017, respectively. F and LSD tests indicated that regarding the difference between the mean scores of perceptions of patient safety and attitudes to patient safety education, there was a significant difference among medical and nursing/midwifery students. Little knowledge of students regarding patient safety indicates the inefficiency of informal education to fill the gap; therefore, it is recommended to consider patient safety in the curriculums of all medical and paramedical sciences and formulate better policies for patient safety.

    Undergraduate students of the twenty-first century are widely regarded as 'technologically savvy' and have embraced the electronic information world. The literature, however, describes undergraduate students as using a limited range of electronic information sources and not critically evaluating the information they retrieve from internet searches. The aim was to evaluate a purposefully designed intervention that sought to expand the information search and evaluation practices of undergraduate students. The intervention scaffolded an independent learning activity in the form of a group-based project. Survey methodology was used to collect data from student pre- and post-intervention for two cohorts of students who undertook the intervention in 2005 and 2006 involving a total of 71 students. Percentages were used to describe survey findings and chi-square analysis and Fisher's exact test examined differences between groups. Questionnaires were completed by 59 students (response rate 83%) pre-intervention and 49 students (response rate 69%) post-intervention. Post-intervention there were positive and statistically significant differences in database searching behaviour (p = 0.000), use of Google Scholar (p = 0.035) and number of criteria used to evaluate information retrieved from the internet (p = 0.000) by students. By positively reshaping the electronic information search and evaluation practices of students we are helping students to find informed information sources as they engage in independent learning activities at university and as future health professionals.

    Full Text Available Background: Daily toothbrushing and flossing are easy, effective and low-cost practices for removing the microbial dental plaque, which is an important factor in the development of caries and periodontal disease. Aim: The objective of this study is evaluation of oral health behaviors in a group of students from an Iranian university . Materials and Methods: This descriptive analytical cross-sectional study was carried out on 1736 Iranian students (1230 non-medical sciences students and 506 medical sciences students. Subjects were randomly selected. The students were asked to fill out a self-completion questionnaire about daily oral health behavior. Statistical Analysis Used: The chi-square test was used for evaluation of oral health behaviors and relationship between students′ oral hygiene behavior and educational levels. Results : There was no difference between the frequencies of tooth brushing in the students of two universities. Medical sciences students used dental floss more than non-medical sciences students, which was a significant difference ( P = 0.000. There was no significant difference in toothbrushing frequency among the students with different levels of education. But the students of doctorate and masters degrees used dental floss significantly more than those of bachelor or associate degrees ( P = 0.000. Conclusions: This study showed that the level of self oral care among Iranian students is at a lower level than in industrialized countries.

    Boarders and day-students study together in regional boarding schools. This study was carried out to compare the health and nutritional status of boarders and day-students who study at regional boarding schools in Turkey. A total 634 boarders and 492 day-students in the 4th-8th years of nine boarding schools in Giresun Province of Turkey were included. A questionnaire including 49 questions about sociodemographic characteristics and health and nutritional status was completed by the students. Height and weight measurements of the students were also taken. The chi-square test was used for statistical analyses. The boarders evaluated their health status as worse than the day-students. The proportion of the students having three meals a day was higher among the boarders than the day-students. According to BMI values, 11% of the boarders were evaluated as underweight, 77% as normal, 9.5% as overweight, and 2.5% as obese. These proportions were respectively 15.5%, 67.3%, 12.8%. and 4.5% for the day-students. The boarders have more regular diets and the proportion of normal-weighed boarders was higher than that of the day-students. However, they perceived their health as worse than the day-tudents.

    To identify what educational resources are used by medical students for their personal study during Primary health care (PHC) clinical rotation and the reasons for making these choices at King Saud University in Riyadh, Saudi Arabia. A survey of 176 male and female medical students was conducted during PHC rotation. A self-administered questionnaire ascertained the type of educational source with reason and preferred type of teaching method. Responses by male and female students were compared by using Pearson's Chi-square tests. Of the 176 students, 85.8% used handouts, 77.3% used the internet, and 46.6% used textbooks. Of the three types of resources, 14.8% used one, 31.8% used all three sources, and 53.4% used two sources. Reasons for selecting a resource were; educational materials are up to the point (88.6%), convenient (85.2%), reliable (77.3%) fit the learning style (77.3%), exam focus (60.8%), recommended by seniors (57.4%), recommended by department (56.8%). The preferred teaching method was lecture (79.5%), and least preferred was student presentations (55.1%). Female medical students used internet related material greater than the males (86.9% versus 68.5%; p value students. Medical students used multiple resources for relevance and convenience. Female students used network resources more than male students.

    Dietetics students' reservations about their career choice were investigated. In several dietetics programs in various provinces, an in-class or online survey was administered to students in the early or late stages of their education (n=397). Data were coded and analyzed, using descriptive statistics. Chi-square testing for independence was used to establish significant relationships. Forty-three percent (n=149) of those responding to the research question (n=344) indicated they had reservations about a dietetics career, primarily because of internship, salary, and employment concerns. Students enrolled in a coordinated internship/degree program experienced no reservations about internship. Students experienced fewer career reservations when they had made their career decision before grade 12, were influenced by a dietitian, or were in the later stages of their education. Findings have implications for dietetics recruitment, retention, research, and education. An understanding of sources of reservations about career choice will allow policy-makers, researchers, and educators to address issues to ensure that potential professionals are well informed about career components and that educational programs meet students' needs.

    To assess the levels of stress in the face of terrorism and the adopted coping strategies, amongst the student population of universities in Karachi. A descriptive, cross sectional study was conducted on undergraduate students from four universities of Karachi. Self-administered questionnaires were filled out by 291 students. Pearson Chi-Square test was used to assess associations between stress levels and different variables at a level of significance of 0.05%. A total of 65.8% of the students had mild stress levels, 91.5% of university students were exposed to terrorism through television, while only 26.5% students reported personal exposure to terrorism. 67.4% students were forbidden by their parents to go out (p = 0.002). Most of those who had self exposure to an attack were the ones whose parents forbade them from going out (p = 0.00). Most commonly used coping strategy was increased faith in religion. Irritability was the most common stress symptom. A majority of students studying in universities of Karachi had mild stress levels due to the constant threat of terrorism whereas a minority had severe stress levels. Possible reasons for resilience and only mild stress levels could be the history of Karachi's internal conflicts and its prolonged duration of being exposed to terrorism. These students who are positive for stress need to be targeted for counseling either through the media or through their universities. More extensive research is needed in this area.

    This study investigated gender inequality in biology lessons and analysed the effects of the observed inequality on students' short-term knowledge achievement, situational interest and students' evaluation of teaching (SET). Twenty-two biology teachers and 803 7th-grade students from rural and urban classrooms in China participated in the study. Each teacher was videotaped for 1 lesson on the topic blood and circulatory system. Before and after the lessons, the students completed tests and questionnaires. Chi-square analysis was conducted to compare the boys' and girls' participation rates of answering teachers' questions in the lessons. The findings revealed that in the urban classrooms the boys had a significantly higher rate of participation than did the girls, and hence also a higher situational interest. However, no such gender inequity was found among the rural students. The study also revealed that urban students answered more complicated questions compared with the rural students in general. The findings of this study suggest that the teachers should try to balance boys' and girls' participation and involve more students in answering questions in their lessons. The study also raises questions about long-term effects of students' participation in answering teachers' questions on their outcomes-knowledge achievement, situational interest and SET.

    Research on occupational therapy students has often been concerned with quite narrow topics. However, the basic characteristics of this group are yet to be examined in more depth. This study aimed to explore the sociodemographic, education-related, and work-related characteristics of occupational therapy students. A sample of 160 occupational therapy students in Norway participated. Differences between cohorts of students were examined with one-way analyses of variance (ANOVA) for continuous variables and with chi-square tests for categorical variables. The sample had a mean age of 24 years and was predominantly female (79%). More than one -third of the students had one or both parents in an occupation requiring health education, whereas two-thirds of the students had one or both parents in an occupation requiring higher education. At entry, 57% of the participants had occupational therapy as their preferred choice of education and 43% had previous higher education experience. The few significant differences between the study cohorts were negligible. In the education programmes, specific attention may be considered for students with characteristics associated with increased risk of poorer study performance or other problems. This may concern male students and students with no previous higher education experience.

    A number of studies of nursing and midwifery have found stress and bullying to be frequent problems. Those suffering from bullying and stress need to have high levels of assertiveness to resist and to cope successfully. Hence, it was considered vital to assess the assertiveness level of nursing students throughout their training curriculum. The study population was composed of nursing students in different semesters at one school in Central Greece (n=298) who agreed to complete a questionnaire on assertiveness level assessment, which had been translated into Greek and adapted to this population. All students present in class completed the questionnaire, representing 80% of the total population of active students. Mean assertiveness scores between semesters were compared by ANOVA and comparisons between the responses of the first semester students and responses of advanced semester students were done by Pearson's chi square. The main finding of this study was that the assertiveness levels displayed by students increase slightly in advanced semesters by comparison to those displayed by first-semester students. Assertive behavior should be encouraged through learning methods. Nurses should preferably obtain this training throughout their studies. Instructors have an essential role in the improvement and achievement of assertiveness training curriculums for undergraduate nursing students.

    Full Text Available Objective – To investigate whether there are any demographic trends affecting student engagement with online library instruction which might have implications for practice, the authors designed a case study to examine the relationship between student demographic characteristics and engagement with online library instruction modules in English 102 courses at a single university. Methods – The authors recruited 181 students from English 102 (ENG 102, a research-based composition course, to participate in the study. ENG 102 instructors asked all participants to complete an online library instruction module embedded in the university’s course management system, either before in-person library instruction or in lieu of face-to-face library instruction. No external incentive was provided for online module completion. The research team measured levels of student engagement by recording the amount of time students spent on each page of the online module. In collaboration with the Office of Institutional Research, the authors then pulled demographic data on each participant using the university’s student information system. Pearson chi-square tests were performed to determine whether there were any notable associations between levels of student engagement and student age, grade point average, gender, and race/ethnicity. Results – Observable trends tied age and higher grade point average to higher levels of engagement with online instruction. There was additionally a slight trend linking female participants to higher levels of engagement than their male peers. In the category of race/ethnicity, the two largest subgroups, Hispanic and Caucasian students, exhibited similar levels of engagement. Conclusions – The authors conclude that there may be demographic implications for practice in designing online library instruction programs, especially when considering student age and academic performance indicators. They also conclude that, owing to

    Full Text Available Objective: We identified associations between time spent watching television and time spent playing video or computer games or using computers and involvement in interpersonal violence, alcohol and drug use in a nationally representative sample of United States high school students.Methods: We analyzed data from the 2007 national Youth Risk Behavior Survey. Exposure variables were time spent watching television and time spent playing computer or video games or using computers (hereafter denoted as “computer/video game use” on an average school day; outcome variables included multiple measures assessing involvement in violence and alcohol or drug use. Chi-square tests were used to identify statistically significant associations between each exposure variable and each of the outcome variables. We used logistic regression to obtain crude odds ratios for outcome variables with a significant chi-square p-value and to obtain adjusted odds ratios controlling for sex, race, and grade in school.Results: Overall, 35.4% (95% CI=33.1%-37.7% of students reported frequent television (TV use and 24.9% (95% CI=22.9%-27.0% reported frequent computer/video game use. A number of risk behaviors, including involvement in physical fights and initiation of alcohol use before age 13, were significantly associated with frequent TV use or frequent computer/video game use, even after controlling for sex, race/ethnicity and grade.Conclusion: Findings highlight the need for additional research to better understand the mechanisms by which electronic media exposure and health-risk behaviors are associated and for the development of strategies that seek to understand how the content and context (e.g., watching with peers, having computer in common area of media use influence risk behaviors among youth.

    This study evaluated the effect of dental education on oral health-related attitudes and behavior of students in a five-year dental program in Peru. A survey using the Hiroshima University-Dental Behavioral Inventory (HU-DBI), which consists of twenty dichotomous responses (agree-disagree) regarding oral health behavior and attitudes, was completed by Year 1 and Year 5 dental students at the Universidad Inca Garcilaso de la Vega in Lima, Peru. A total of 153 Year 1 students and 120 Year 5 students responded to the Spanish version of the HU-DBI questionnaire. The data were analyzed using chi-square tests and logistic regression analyses. Compared to the Year 1 students, the Year 5 dental students were more likely to agree with questions such as "I think I can clean my teeth well without using toothpaste" (OR=0.24, 95% CI: 0.10-0.58); "I have used a dye to see how clean my teeth are" (OR=0.19, 95% CI: 0.10-0.36); and "I have had my dentist tell me that I brush very well" (OR=0.34, 95% CI: 0.17-0.69). Overall, the data showed that the curriculum in this dental school in Peru resulted in more positive oral health-related attitudes and behavior among Year 5 dental students compared to those of Year 1 dental students.

    To ensure safe, effective and rational prescribing by tomorrow's doctors it is important to assess the prescribing skills of today's medical students. The aim of this study was to assess the prescribing skills of MBBS preclinical students of a Teaching Hospital. First and second year medical students were given different sets of common clinical scenarios and asked to write a prescription for these. The physician and drug related components were analyzed following the WHO guidelines. The data were statistically analyzed using Chi-square test for 99% and 99.99% Confidence Intervals. P values first year student scored 123 (82%) and 94 (62.66%) in physician and drug related component respectively. MBBS second year students scored 139 (92.66%) and 111 (73.33%) in physician and drug related components respectively. Results obtained from the element prescriber's address and telephone number, date of prescription and patient's address on the prescription of first year and second year medical students were highly significant (pfirst and second year MBBS students is not satisfactory. Prescribing deficiencies were found on both the physician and drug related components which emphasizes the need of adequate prescribing knowledge in order to minimize the prescription errors and irrational prescribing. Based on this study, we suggest all the undergraduate medical students should be regularly trained and evaluated to further help minimize the prescribing errors.

    Little is known about correlates of overweight, obesity, and physical inactivity among African American students at historically Black colleges and universities. To assess overweight, obesity, and physical inactivity among African American college students at a historically Black university in Maryland in the USA. Data were collected from 268 African American college students in 2013. Data were analyzed with percentage difference z-tests, chi-square tests, and multiple logistic regression. Cross-sectional survey (student response rate = 49.9%). The overweight/obesity rate of participants was 47.5%, which was higher than that of the U.S. college student population overall (34.1%) and a representative sample of African American college students (38.3%). When age and sex were controlled, a family history of obesity, skipping breakfast, drinking caffeinated drinks, lower family income, and smoking a pipe, cigars, or cigarettes daily were significant correlates of overweight (obesity included). The percentage of physical inactivity was 68.3, and physical inactivity was higher among women and overweight or obese students. Given the high overweight and obesity prevalence among African American college students, historically Black colleges and universities in the USA should increase health promotion efforts targeting weight-related behaviors, particularly physical activity.

This study aimed at assessing the use of mobile learning technology and its challenges among final year undergraduate students in the College of Health sciences, University of Nairobi. This was a cross-sectional descriptive study conducted among final year undergraduate students at the University of Nairobi, College of Health Sciences. Self-administered, anonymous questionnaires were issued to all final year students in their lecture rooms after obtaining informed consent. Data on demographics, mobile device ownership and mobile learning technology use and its challenges was collected. Data entry and analysis was done using SPSS(®). Chi-square and t-test were used for bivariate analysis. We had 292 respondents; 62% were medical students, 16% were nursing students, 13% were pharmacy students and 9% were dental surgery students. The majority were female (59%) and the average age was 24 years. Eighty eight percent (88%) of the respondents owned a smart device and nearly all of them used it for learning. 64% of the respondents used medical mobile applications. The main challenges were lack of a smart device, lack of technical know-how in accessing or using apps, sub-optimal internet access, cost of acquiring apps and limited device memory. Mobile learning is increasingly popular among medical students and should be leveraged in promoting access and quality of medical education.

    Full Text Available Introduction: The concepts about dental caries and periodontal diseases are learned at dental schools may directly influence the conduct of the future dentists regarding the control and treatment of these diseases. Aim: To assess the variation in the understanding of the concepts of dental caries and periodontal diseases among first to final year undergraduate dental students. Materials and Methods: A cross-sectional, questionnaire-based study was conducted among 400 students pursuing their graduation in a private dental college situated in Sri Ganganagar city, Rajasthan, India. Descriptive analysis was done, and Chi-square test with a significance level of 5% was done to compare the frequency based data. Results: For concepts related to dental caries, the 1st year students' response showed shift toward biological concept, which was also present for the 2nd year but the 3rd year onwards the majority of students cited the comprehensive multi-factorial concept (P = 0.0002. Final year students were more knowledgeable than the 1st, 2nd, and 3rd year students regarding gingival bleeding, swelling, redness, and bad breath being the most important signs of periodontal disease (P = 0.004. Conclusion: Significant variation in the school of thoughts and limited knowledge regarding the concepts of common dental diseases among dental undergraduate students is seen. There might be a need to reform the initial concept building methods utilized in dental institutions to improve the basic knowledge of undergraduate students of the common dental diseases.

    Safety culture may exert an important influence on the adoption and learning of patient safety practices by learners at clinical training sites. This study assessed students' perceptions of safety culture and identified curricular gaps in patient safety training. A total of 170 fourth-year medical students at the University of California, San Francisco, were asked to complete a modified version of the Agency for Healthcare Research and Quality Hospital Survey on Patient Safety Culture in 2011. Students responded on the basis of either their third-year internal medicine or surgery clerkship experience. Responses were recorded on a five-point Likert scale. Percent positive responses were compared between the groups using a chi-square test. One hundred twenty-one students (71% response rate) rated "teamwork within units" and "organizational learning" highest among the survey domains; "communication openness" and "nonpunitive response to error" were rated lowest. A majority of students reported that they would not speak up when witnessing a possible adverse event (56%) and were afraid to ask questions if things did not seem right (55%). In addition, 48% of students reported feeling that mistakes were held against them. Overall, students reported a desire for additional patient safety training to enhance their educational experience. Assessing student perceptions of safety culture highlighted important observations from their clinical experiences and helped identify areas for curricular development to enhance patient safety. This assessment may also be a useful tool for both clerkship directors and clinical service chiefs in their respective efforts to promote safe care.

    Urology training programs seek to identify ideal candidates with the potential to become competent urologic surgeons. It is unclear whether innate technical ability has a role in this selection process. We aimed to determine whether there are any innate differences in baseline urologic technical skills among medical students. Second-year medical students from the University of Toronto were recruited for this study and stratified into surgical and non-surgical cohorts based on their reported career aspirations. After a pre-test questionnaire, subjects were tested on several urologic surgical skills: laparoscopy, cystoscopy and robotic surgery. Statistical analysis was performed using chi-squared test, student t-tests and Spearman's correlation where appropriate. A total of 29 students participated in the study and no significant baseline differences were found between cohorts with respect to demographics and prior surgical experience. For laparoscopic skills, the surgical cohort outperformed the non-surgical cohort on several exercises: Lap Beans Missed (4.9 vs. 9.3, p robotic surgery performance metrics: Task Time (50.6 vs. 76.3, p robotics, may differ between early trainees interested in a surgical career compared to those interested in a non-surgical career. Further studies are required to illicit what impact such differences have on future performance and competence.

    Full Text Available Abstract Background Burnout syndrome (BS is a set of psychological symptoms resulting from the interaction between chronic occupational stress and individual factors. These symptoms include emotional exhaustion, depersonalization and decreased professional satisfaction. BS is manifested in a variety of professions and is prevalent in contexts in which health professionals are required to interact directly with the public. Objective To determine the prevalence of BS among medical students at a university in Ceará State, Brazil. Methods Of the 517 students enrolled in their first to eighth semester in 2013, 376 (72.7% were contacted. A socio-economic evaluation questionnaire and the Maslach Burnout Inventory – Human Services Survey (MBI-HSS were administered. Statistical analysis was conducted using SPSS 20.0. Two groups – burnout/risk and non-burnout – were compared using the chi-square and likelihood ratio tests with a significance level of 5%. Variables with p < 0.20 were included in a multivariate analysis logistical regression model. Results Burnout was detected in 14.9% of the students, and 57.7% showed a risk of developing the syndrome. Logistic regressions showed an association between burnout and “have failed examinations” and “have considered abandoning the course”, p = 0.047 and p < 0.0001, respectively. Discussion Psychopedagogy should be implemented to address the high prevalence of burnout in medical students.

    To assess the influence of pharmaceutical advertising (in the form of books) directed at medical students and also to examine students' attitudes toward pharmaceutical representatives after interacting with them. Two groups of fourth-year medical students were surveyed: 166 residency applicants to the Department of Anesthesia and Critical Care between 1991 and 1993, who were questioned during their personal interviews with the department chair, and 39 fourth-year students from the University of Chicago Pritzker School of Medicine in 1994-95, who were surveyed by telephone. The students were asked if they had ever received a book from a pharmaceutical representative and, if so, to name the book. Then they were asked to name the book-giving company or a product associated with the company. Responses were compared using chi-square analysis. In all, 90% of the students had received one or more books and accurately recalled titles for 89% of them. However, only 25% of the named books were accurately associated with a pharmaceutical company or product. The Pritzker students, asked to recall interactions with pharmaceutical representatives, reported being skeptical of representatives who ignored them because they were students, but they rated as helpful and informative those who conversed with them or gave them gifts. Although gifts to medical students do not necessarily engender company or product recall, attention paid to medical students by pharmaceutical representatives engenders goodwill toward the representatives and their messages.

    Full Text Available Problem statement: At present, after almost more than 20-decades, Malaysia can boast of a solid national philosophy of education, despite tremendous struggles and hopes. The professional learning opportunities are necessary to enhance, support and sustain student's mathematics achievement. Approach: Empirical evidence had shown that student's belief in mathematics is crucial in meeting career aspiration. In addition mathematical beliefs are closely correlated to their mathematics achievement among university students. Results: The literature exposed that a few studies had been done on university undergraduates. The present study involves a sample of eighty-six university undergraduate students, who had completed a self-reported questionnaire related to student mathematical beliefs on three dimensions, viz-a-viz beliefs about mathematics, beliefs about importance of mathematics and beliefs on one's ability in mathematics. The reliability index, using the Cronbach's alpha was 0.86, indicating a high level of internal consistency. Records of achievement (GPA were obtained from the academic division, University Putra Malaysia. Based on these records, students were classified into the minor and major mathematics group. The authors examined student's mathematical beliefs based on a three dimensional logistic regression model estimation technique, appropriate for a survey design study. Conclusion/Recommendations: The results illustrated and identified significant relationships between student beliefs about importance of mathematics and beliefs on one's ability in mathematics with mathematics achievement. In addition, the Hosmer and Lemeshow test was non-significant with a chi-square of 8.46, p = 0.3, which indicated that there is a good model fit as the data did not significantly deviate from the model. The overall model, 77.9% of the sample was classified correctly.

    Full Text Available Objectives. To explore and compare undergraduate dental students’ views and preferences towards various teaching strategies. Methods. A questionnaire was developed and distributed to 345 male and female undergraduate dental students from the two major dental schools in Riyadh (College of Dentistry, King Saud University [KSU], and Riyadh Colleges of Dentistry and Pharmacy [RCsDP]. Students’ preferences for various components of the lecture courses were investigated. Descriptive and crosstab analyses were used to compare the students’ preferences for each school and between genders; the chi-square test was used to measure the significance level (P=0.05. Results. The majority of students preferred having the lecture schedule announced in advance. Females preferred morning lectures, whereas male students preferred afternoon lectures. Nearly half of the students thought that attending lectures should be mandatory; most of them were from KSU. Most of the students reported preferring a PowerPoint presentation lecture. The students, particularly female students, also preferred to receive lecture handouts and study materials before the session and to have practical demonstrations after the lecture. Conclusion. Teachers should consider students’ opinions when constructing courses because this feedback would have a positive impact on the teaching environment and students’ performance.

    The purpose of this study was (1) to determine the personality characteristics of dental hygiene students, and (2) to determine if dental hygiene students have personality characteristics similar to those of the general population. Students from three non-baccalaureate degree programs were requested to complete a demographic questionnaire and the Myers-Briggs Type Indicator (MBTI). Eighty-six percent of the 124 students responded. The MBTI data was analyzed using frequency distributions, electivity indices, and chi-square analyses. Individuals categorized as ESFJ (extraversion, sensing, feeling, and judging) and ISFJ (introversion, sensing, feeling, and judging), two of the possible 16 MBTI personality types, comprised 39% of the sample. These two personality types were found in significantly greater numbers in the study population than in a random sample of the general population. People with the ISTJ (introversion, sensing, thinking, and judging), INFP (introversion, intuition, feeling, and perception), and INFJ (introversion, intuition, feeling, and judging) MBTI personality types were found in significantly lesser numbers in the study population than in a random sample of the general population. This suggests that dental hygiene students are not drawn at random from the general population. Self-knowledge, as measured by the MBTI, could prove beneficial for prospective dental hygiene students, students currently enrolled in dental hygiene programs, and educators. Additionally, practicing dental hygienists might find that the MBTI personality assessment results could help them identify career paths in the field that would enhance career fulfillment, thereby increasing the retention of professionals in the field.

    Staphylococcus aureus is usually considered a colonizer but can result in infections under favourable conditions, especially in the healthcare setting. Healthcare workers can be colonized by S. aureus, and may transmit them to patients under their care. We conducted a cross sectional study to determine the prevalence of S. aureus nasal carriers among medical students in Universiti Putra Malaysia (UPM) (from January to June 2011). Our study involved 209 medical students comprising of 111 and 97 preclinical and clinical students respectively. A selfadministered questionnaire was distributed and nasal swabs were collected. Upon identification, the antibiotic susceptibility of the isolates was examined followed by categorical analysis (Chi-square and Fisher's exact tests) with factors associated with S. aureus nasal carriage. Twenty one (10%) S. aureus strains were isolated from 209 nasal swab samples. 14 isolates were from pre-clinical students while the remaining seven were from clinical students. There was no significant association between gender, ethnicity, health status, skin infection and students' exposure to hospital environment with S. aureus nasal carriage (p>0.05). Nineteen (90.5%) isolates were resistant to penicillin and there was also no significant association between penicillin resistant and the students' groups. One (5.3%) isolate was resistant to erythromycin. There was no methicillin-resistant S. aureus isolated in this study.

    To examine the exercise behavior of 953 Turkish university students (496 men, 457 women) by sex, residence, and department of study, a stratified sampling method, based on the total number of students in each department, was used to select participants. The mean age of the participants was 21.3 yr. (SD = 1.9). For completed Physical Activity Stages of Change Questionnaire and the International Physical Activity Questionnaire, descriptive statistics and chi-squared tests indicated that most students were at the lower stages of change in exercise habits: Precontemplation (15.2%), Contemplation (31.4%), and Preparation (25.3%), compared with the later stages of Action (7.5%) and Maintenance (20.6%). Women and students from the Department of Architecture were at lower stages of change than men and students from other departments (p < .05), but there were no significant differences between students who were living on or off campus. Stage-based interventions would be appropriate, with focus on the physical activity of women and students in architecture.

    The understanting of the dental fluorosis process, that begins with enamel maturation, is important to Dentistry students, since fluoride has drastically decreased the incidence of caries in several population groups, with a resultant increase in fluorosis prevalence and severity, as shown in literature. The objective of this paper is to report the changes in the level of knowledge about dental fluorosis of undergraduate Dentistry students at Guarulhos University. One hundred and twenty-four undergraduate students enrolled in the first and second semester (2008) and seventh semester (2008) were evaluated. The data was obtained through questionnaires with dichotomic questions (true and false) and an alternative to evaluate whether the subject had been presented in the classroom. The data obtained was submitted to statistical analysis using the Chi-square test (α=0.05). When evaluating the first semester students, differences were verified in numbers of the questions assigned with the alternatives true or false, when compared with seventh semester students (psemester students after six months (p=0.358). It is possible to conclude that the six months period was insufficient to increase the level of knowledge about dental fluorosis, and when the students beginning and concluding the dentistry course were compared, there was an increase in the number of correctly assigned true or false questions in the latter group.

This descriptive study was performed on nursing students at Black Sea Universities in the academic year 2010-2011. Data were collected using a structured questionnaire about students' attitudes regarding patients' rights including patient's rights regulations. The association between gender and students' attitudes was analyzed using Chi-square test. The mean age of the 238 participants was 22.11 ± 1.21 years and 82.8% of them were female. The majority of the nursing students held desirable attitudes toward patient information, truth telling, and protection of patients' privacy and medical records. However, the students' views about the rights of patients to refuse treatment, children's active participation in treatment, prioritization of the quality of life in treatment, and respect for the rights of dying patients were less satisfactory. The results of this study was concerning with regard to nursing students' readiness for duties such as patient's rights advocacy. Therefore, it proposes ethics education that covers both patient's rights and the obligations of nurses to defend these rights.

    Our research project aimed at presenting midwifery student self-assessment of performing the role of breast cancer prevention educator. Investigations were carried out in 2011 at the Medical University of Lublin in Poland, and Katolieke Hogeschool of Kortrijk in Belgium, after obtaining approval of the ethical committee of Polish Midwives Association (III/EC/2011/PMA). The project involved a total of 155 midwifery students, made up of 95 from Poland, and 60 from Belgium. Relations between opposing characteristics were tested with Chi-square (x2) test for independent traits. To assess the dependence relation between the examined variables Pearson's corrected coefficient was used. Data base and statistics were carried out with computer software STATISTICA 9.0 (StatSoftPoland). Student knowledge on prevention against breast cancer was unsatisfactory.The students place of residence determined their self-estimation of personal knowledge of breast cancer prevention and diagnosing methods to assess the incidence of the disease, this knowledge being better with the students of Lublin. Better self-estimation in the students of Lublin of their personal knowledge on factors rising the risk of breast cancer, such as alimentation method, application of oral contraceptives and breast feeding was found than in Belgian students.

    Full Text Available Background: The understanting of the dental fluorosis process, that begins with enamel maturation, is important to Dentistry students, since fluoride has drastically decreased the incidence of caries in several population groups, with a resultant increase in fluorosis prevalence and severity, as shown in literature. Aims: The objective of this paper is to report the changes in the level of knowledge about dental fluorosis of undergraduate Dentistry students at Guarulhos University. Subjects and Methods: One hundred and twenty-four undergraduate students enrolled in the first and second semester (2008 and seventh semester (2008 were evaluated. The data was obtained through questionnaires with dichotomic questions (true and false and an alternative to evaluate whether the subject had been presented in the classroom. The data obtained was submitted to statistical analysis using the Chi-square test (α=0.05. Results: When evaluating the first semester students, differences were verified in numbers of the questions assigned with the alternatives true or false, when compared with seventh semester students (p<0.001. However, there were no differences when the same questionnaire was applied to the first semester students after six months (p=0.358. Conclusions: It is possible to conclude that the six months period was insufficient to increase the level of knowledge about dental fluorosis, and when the students beginning and concluding the dentistry course were compared, there was an increase in the number of correctly assigned true or false questions in the latter group.

    Full Text Available Purpose: The aim of this study was to analyze the smoking prevalence among dental students and to assess the need for promoting tobacco education and intervention by exploring their knowledge about smoking related risk factors. The study also examined the attitudes and practices of the students toward tobacco consumption, and their responsibilities toward the community. Methods: In total, 53 male students participated in the study (21 juniors and 32 seniors. The training program was divided into three modules, and the questionnaire was administered before and after the counseling sessions, which provided the comparative data on the students’ views about smoking cessation. Results: The most commonly practiced mode of tobacco consumption was found to be cigarette smoking (90.6 %, while a few consumed Gutkha (9.4%. All the junior students (100% reported to have been benefitted by the counseling program, while 68.8% of the students from the senior group reported the same. Bivariate statistical analysis was conducted using the Pearson’s chi-square test for testing the difference across the age groups. P-values less than 0.05 were considered statistically significant. Conclusion: Curbing tobacco influence on dental students in their initial days can ensure a smoke-free life for them, as well as prevents them from feeling embarrassed or experiencing a lack of confidence while seeing their patients. Thus, tobacco education and intervention programs can motivate the students and increase their potential to be credible advisors regarding smoking cessation.

    Full Text Available Abstract Background We have previously shown that irregular lifestyle of young Japanese female students are significantly related to their desire to be thinner. In the present study, we examined the nutritional knowledge and food habits of Chinese university students and compared them with those of other Asian populations. Methods A self-reported questionnaire was administered to 540 students, ranging in age from 19-24 years. Medical students from Beijing University (135 men and 150 women in Northern China and Kunming Medical College in southern China (95 men and 160 women participated in this study. The parametric variables were analyzed using the Student's t-test. Chi-square analyses were conducted for non-parametric variables Results Our results showed that 80.5% of students had a normal BMI and 16.6 % of students were underweight with the prevalence of BMI>30 obesity being very low in this study sample. Young Chinese female students had a greater desire to be thinner (62.0% than males (47.4%. Habits involving regular eating patterns and vegetable intake were reported and represent practices that ought to be encouraged. Conclusions The university and college arenas represent the final opportunity for the health and nutritional education of a large number of students from the educator's perspective. Our findings suggest the need for strategies designed to improve competence in the area of nutrition.

    To study the prevalence of cardiovascular risk factors in asymptomatic university students of both sexes, aged 18 to 25 years. Serum lipid levels were measured in a subsample of 293 subjects, using a Hitachi 717 chemical analyzer. Obesity was classified using body mass index (BMI) measurements. A self-applied questionnaire was used to collect data on sedentary life style, family history of cardiovascular disease and cigarette smoking. Statistical associations of lipid levels with lipidic and non-lipidic risk factors were assessed using Pearson's chi-square test and multiple regression. We found lipid risk levels in 29.2% for total cholesterol (CT), 16.2% for low-density lipoproteins (C-LDL) and 5% for high-density lipoproteins (C-HDL). The main non-lipidic factors were smoking (46.1%) and sedentarism (60.8%). Obesity, hypertension and parental history of myocardial infarction were present in 1.9%, 4.6% and 11%, respectively. We observed an association of a lipid risk profile with obesity, cigarette smoking and family history. The results show that sedentarism and smoking are associated with a lipid risk profile. These results call for the need to develop appropriate behavior strategies for the successful prevention of cardiovascular disease.

  10. The Lasso Problem and Uniqueness

    CERN Document Server

    Tibshirani, Ryan J

    2012-01-01

    The lasso is a popular tool for sparse linear regression, especially for problems in which the number of variables p exceeds the number of observations n. But when p>n, the lasso criterion is not strictly convex, and hence it may not have a unique minimum. An important question is: when is the lasso solution well-defined (unique)? We review results from the literature, which show that if the predictor variables are drawn from a continuous probability distribution, then there is a unique lasso solution with probability one, regardless of the sizes of n and p. We also show that this result extends easily to $\\ell_1$ penalized minimization problems over a wide range of loss functions. A second important question is: how can we deal with the case of non-uniqueness in lasso solutions? In light of the aforementioned result, this case really only arises when some of the predictor variables are discrete, or when some post-processing has been performed on continuous predictor measurements. Though we certainly cannot c...

    Full Text Available Being and becoming is the ultimate objective of any educational enterprise, including language teaching. However, research results indicate seemingly unjustified differences between how females and males are treated by EFL (English as a Foreign Language teachers. The overall aim of this study is to illustrate, analyze, and discuss aspects of gender bias and gender awareness in teacher–student interaction in the Iranian college context. To this end, teacher–student interactions of 20 English teachers and 500 students were investigated from the perspective of gender theory. The data were obtained via classroom observations, a seating chart and the audio-recording of all classroom interactions during the study. The findings, obtained from the quantitative descriptive statistics and chi-square methods, as well as the qualitative analysis by way of open and selective coding, uncovered that there were significant differences in the quantity and quality of the interaction for females and males in almost all categories of interaction. The study also revealed teachers’ perception of “gender,” the problems they associate with gender, and the attitudes they have to gender issues. Apparently, while positive incentives are able to facilitate learner growth, the presence of any negative barrier such as gender bias is likely to hinder development. This has implications for teachers, and faculty members who favor healthy and gender-neutral educational climate.

    The Alpbach Summer School is a ten-day program that provides a unique opportunity for young european science and engineering students, both undergraduate and graduate, to learn how to approach the entire design process of a space mission. The theme of the 2010 Summer School was "New Space Missions to Understand Climate Change", a current, challenging, very broad and complex topic. The program was established more than 35 years ago and is organised in two interrelated parts: a series of lectures held by renowned experts in the field (in the case of this specific year, climate change and space engineering experts) that provides a technical and scientific background for the workshops that follow, the core of the Summer School. For the workshops the students are split into four international, interdisciplinary teams of about 15 students. In 2010 every team had to complete a number of tasks, four in total: (1) identify climate change research gaps and design a space mission that has not yet been flown or proposed, (2) define the science objectives and requirements of the mission, (3) design a spacecraft that meets the mission requirements, which includes spacecraft design and construction, payload definition, orbit calculations, but also the satellite launch, operation and mission costs and (4) write up a short mission proposal and present the results to an expert review panel. Achieving these tasks in only a few days in a multicultural, interdisciplinary team represents a major challenge for all participants and provides an excellent practical learning experience. Over the course of the program, students do not just learn facts about climate change and space engineering, but scientists also learn from engineers and engineers from scientists. The participants have to deepen their knowledge in an often unfamiliar field, develop organisational and team-work skills and work under pressure. Moreover, teams are supported by team and roving tutors and get the opportunity to

    The Tri-Border Region has several social and health problems among young people, however, there are no data about the overweight between adolescents. This study investigated the prevalence of overweight and associated factors in students from Tri-Border Region: Argentina, Brazil and Paraguay. Study participants were 1.183 students, ages from 15 to 18 years. The overweight was identified according to body mass index cut-off points proposed by the World Health Organization. The Global School-Based Student Health Survey questionnaire was used to identify sociodemographic (gender and age) and behavioral factors (physical activity outside of school, commuting to school, time watching TV and fruits, vegetables, sweet, and salty snack consumption) associated with overweight in adolescents. It was used the descriptive statistics, analysis of variance, chi-square and binary logistic regression, adopting p < 0.05. Thirteen percent of students were overweight. Boys were approximately two times more likely to have overweight than girls, independently of nationality. Brazilian students that realized passive commuting to school and Argentineans students with low consumption of vegetables (< 1 time/day) were 2.2 and 2.9 times more likely to have overweight than their counterparts who performed active commuting to school and consumed vegetables daily, respectively. These results suggest that public policies to combat overweight should attention on promoting healthy lifestyle among young people from Tri-Border Region.

    Physical inactivity is a well-known risk factor for many chronic diseases which have high prevalence in developed countries. The aims of this study are to describe leisure-time physical activity levels and to identify preferences for its practice among first grade students in three Health Sciences Faculties at the University of Barcelona. During the year 1994-95, a total of 887 first grade students of three Faculties, Pharmacy (n = 573), Medicine (n = 222) and Dentistry (n = 92), were interviewed using a recall of their leisure time physical activity over last 8 months. Physical activity level was classified into four categories: non-active, low, medium and high, based on the number of hours per week. Statistical methods consisted in the estimation of rates, comparisons using the chi-square test, and computing the odds ratio. Women were 75% of students. Fifty per cent of men and 71.5% of women referred to be non-active or having low physical activity level (chi 2 = 36.8; DF = 3; p or = 25). Among the rest of students, men's most frequently reported activities were football, swimming and tennis, and those of women's were swimming, aerobic and tennis. Physical activity level among first grade health sciences university students is poorly exemplary. More physical activity promotion is needed, particularly to female students, as an important primary preventive measure among this group.

A cross-sectional study was conducted among 199 students in the period from December of academic year 2009 until April of academic year 2010 in Management and Science University (MSU), Shah Alam, Selangor, Malaysia. The questionnaire was distributed randomly to all faculties of MSU by choosing one of every 3 lecture rooms, as well as the library and cafeterias of the campus randomly by choosing one from every 3 tables. Questions concerned socio-demographic variables, knowledge, attitudes and practice toward smoking. Participant's consent was obtained and ethical approval was provided by the ethics committee of the University. Data entry and analysis were performed using descriptive statistics, chi square test, Student t- test and logistic multiple regression with the SPSS version 13.0, statistical significance being concluded at p students were smokers (29%). The most important reason of smoking was stress (20%) followed by 'influenced by friends' (16 %). Prevalence of smoking was significantly higher among male and those in advanced semesters (p = >0.001, p = 0.047). Smokers had low level of knowledge (p semester of study (p = 0.025) and attitude toward smoking (p students were smokers. Males and students in advanced semesters were more likely to smoke. The results provide baseline data to develop an anti-smoking program to limit smoking in the university by implementing policies against smoking.

    Full Text Available Background: there are problems with enrollment in medical science programs due to the lack of proper vocational guidance. Objective: to evaluate a set of actions to promote vocational guidance in 12th-grade students attending senior high schools in Cienfuegos province. Methods: a qualitative and quantitative research was conducted comprising 523 students in the preparatory groups for entering medical school programs in Cienfuegos, 105 faculty members and 20 officials of the Provincial Education Department. The research study was divided into two parts, one devoted to the organization and planning of activities with the students, and the second part focused on their implementation and evaluation. The level of student and faculty satisfaction with the set of actions was analyzed. A Chi-square test of independence was used with a 95% confidence interval. Results: student’s expectations were met. The level of knowledge about the profession increased and the links between ministries and institutions (MINED-MINSAP were strengthened. There was a correspondence between the level of satisfaction of faculty members, students, and the administrators of the senior high schools, but all believed that family involvement should increase. Conclusions: a well-conceived set of actions favors vocational guidance in medical sciences; however, family involvement should increase, as well as the participation of students attending senior high schools distant from the capital city of the province.

    Science education video game research points toward promising, but inconclusive results in both student learning outcomes and attitudes. However, student-level variables other than gender have been largely absent from this research. This study examined how students' reading ability level and disability status are related to their video game-playing behaviors outside of school and their perceptions about the use of science video games during school. Thirty-four teachers and 876 sixth- through ninth-grade students from 14 states participated in the study. All student groups reported that they would prefer to learn science from a video game rather than from traditional text, laboratory-based, or Internet environments. Chi-square analyses indicated a significant association between reading ability level, disability status, and key areas of interest including students' use of video games outside of school, their perceptions of their scientific abilities, and whether they would pursue a career in the sciences. Implications of these findings and areas for future research are identified.

    This action research project investigated fourth grade students¡¦ motivation to learn science using a digital science techbook. Participants in the study included 29 fourth grade students in two different classrooms. One classroom of 16 students used a digital science techbook to learn science while the other classroom of 13 students used a traditional paper science textbook to learn science. Students in both classrooms answered five sets of questions regarding their experience using a digital science techbook and a paper science techbook to understand science, find science information, solve science problems, learn science, and assess learning science was fun. Results were compiled and coded based on positive and negative responses to conditions. A chi-square was used to analyze the ordinal data. Overall differences between techbooks vs. textbook were significant, X2 (1, N = 29) = 23.84, p = .000, justifying further examination of individual survey items. Three items had statistically significant difference for finding science information, solving science problems, and learning science. A gender difference was also found in one item. Females preferred to use paper science textbooks to understand science, while males preferred digital techbooks to learn science. The fourth graders in this study indicated that digital techbooks were a powerful learning tool for increasing interest, excitement and learning science. Even though students reported paper science textbooks as easy to use, they found using digital science techbooks a far more appealing way to learn science.

    In Japan, the imbalance in the medical workforce has caused a deterioration of rural medicine. We explored the differences in speciality preferences and career determinant factors among students to identify keys to increase the recruitment of physicians to rural areas. We conducted a survey of first- and fifth-year medical students, using a questionnaire enquiring about their specialty preference and career determinant factors. The data were analyzed with a chi-square test. A higher percentage of first-year students preferred to be basic medicine scientists, while fifth-year students considered internal medicine subspecialities, obstetrics and gynecology, anesthesia, and ophthalmology to be the most desirable. The factor analysis yielded five factors responsible for these findings; high social approval of the specialty, working hours, income, advice from senior classmates and doctors, and the work environment. The percentage of students who considered rural practice as a choice for thier future plan and had an awareness of the collapse of rural medicine was lower in the fifth-year students than in the first-year students. To increase the medical work force in provincial areas, it is necessary to strengthen not only the medical system with regard to general medicine, but also to offer better medical education in rural areas. More information about rural practice should therefore be transmitted to medical students.

    Calibration in diagnosis and treatment planning is difficult to achieve due to variations that exist in clinical interpretation. To determine if dental faculty members are consistent in teaching how to diagnose and treat periodontal disease, variations among dental students can be evaluated. A previous study reported high variability in diagnoses and treatment plans of periodontal cases at Indiana University School of Dentistry. This study aimed to build on that one by extending the research to two additional schools: Marquette University School of Dentistry and West Virginia University School of Dentistry. Diagnosis and treatment planning by 40 third- and fourth-year dental students were assessed at each of the schools. Students were asked to select the diagnosis and treatment plans on a questionnaire pertaining to 11 cases. Their responses were compared using chi-square tests, and multirater kappa statistics were used to assess agreement between classes and between schools. Logistic regression models were used to evaluate the effects of school, class year, prior experience, and GPA/class rank on correct responses. One case had a statistically significant difference in responses between third- and fourth-year dental students. Kappas for school agreement and class agreement were low. The students from Indiana University had higher diagnosis and treatment agreements than the Marquette University students, and the Marquette students fared better than the West Virginia University students. This study can help restructure future periodontal courses for a better understanding of periodontal diagnosis and treatment planning.

    Full Text Available Children begin to observe curiously the living and non-living nature they live in. They try to know and define the objects with their various characteristics. In time, they perceive the world and environment regularly and systematically. Some wrong information developed uniquely by the students in such a manner that out of scientific facts in time causes significant obstacles within the learning process. As the children develop, learn and their interaction with the environment increases, the living and non-living concepts take form and have new meanings. In our study, it has been tried to be revealed by means of quantitative data that whether the characteristics of living and non-living things differentiate from each other by gender according to them. Totally 1066 students participated in our study, of which 531 are females and 535 are males, in 12 primary schools determined at random in 7 provinces of Turkey, being one province from each region. In this study descriptive survey model is used. The data was obtained from a questionnaire which is consisting of 14 questions. The quantitative data obtained was analyzed by using SPSS 14 package programme. In this research chi-square test was used for analyzing data. 49.5 % of the female students and 50.5 % of the male students have emphasized that they learned the existence of living and non-living things around them in their families for the first time. 51.4 % of the female students and 48.6 % of the male students have stated that human comes to their minds when living thing is said. 57.9 % of the female students and 42.1 % of the male students participated in the survey have stated that moving is the first thing coming to their mind when the characteristics of living things is said. Whereas 520 students identified that not-moving is the first thing coming to their mind when the characteristics of non-living things is said, this rate is 49% for female students and 51% for male students.

    The classical result for uniqueness in elasticity theory is due to Kirchhoff. It states that the standard mixed boundary value problem for a homogeneous isotropic linear elastic material in equilibrium and occupying a bounded three-dimensional region of space possesses at most one solution in the classical sense, provided the Lame and shear moduli, A and J1 respectively, obey the inequalities (3 A + 2 J1) > 0 and J1>O. In linear elastodynamics the analogous result, due to Neumann, is that the initial-mixed boundary value problem possesses at most one solution provided the elastic moduli satisfy the same set of inequalities as in Kirchhoffs theorem. Most standard textbooks on the linear theory of elasticity mention only these two classical criteria for uniqueness and neglect altogether the abundant literature which has appeared since the original publications of Kirchhoff. To remedy this deficiency it seems appropriate to attempt a coherent description ofthe various contributions made to the study of uniquenes...

    We examine numerically a sequence of free data for the conformal thin sandwich (CTS) equations representing non-linearly perturbed Minkowski spacetimes. We find only one solution for the standard (four) CTS equations; however, we find {\\em two} distinct solutions for the same free data when the lapse is determined by a fifth elliptic equation arising from specification of the time derivative of the mean curvature. For a given {\\em physical} (conformally scaled) amplitude of the perturbation, the solution for the physical data $g_{ij}, K_{ij}$ nevertheless appears to be unique.

    Introspection into the factors that affect student success at higher education institutions has gained significant momentum in recent years. Teaching and learning has come under the spotlight with quality enhancement and teaching development funding focussing on student support, enhancing the student environment, and enhancing academics as teachers. Included in this are aspects that try to understand the student. An aspect that is not receiving attention is student health, specifically headaches which could impact student success. The aim of this study was to investigate the impact of primary headaches on student academic, family and social life at one higher education institution in South Africa. Data was collected using a questionnaire based descriptive cross sectional survey. Multistage sampling using a ballot method allowed for sampling to obtain representation from across the institution. To achieve a 95 % confidence level, 384 students from across the university were invited to participate after informed consent. Data was analysed using Chi square tests at a probability of p consumption of caffeinated energy drinks, coffee and chocolate resulting in a less effective study session. Activities of daily living and participation in social events which usually leads to relaxation were neglected. Personal and emotional well-being was also negatively affected. Altered sleeping patterns and absence of study breaks also led to headaches. Headaches were found to impact on the students study and sleep patterns, their attention levels during lectures and their social and emotional life. Headaches negatively impacted on some participants leading to reduced focus on academic, family, social or leisure activities. Intensity of headaches increased during tests and examinations which could impact their success at University.

Department of Medical Education, Army Medical College, NUST, Rawalpindi, Pakistan, during February and March 2012. A total of 170 students were divided into two equal groups of undergraduate students of Army Medical College, and postgraduate students of Armed Forces Post Graduate Medical Institute, Rawalpindi. Learning Style Questionnaire (LSQ) was used to assess and categorize the participants into Honey and Mumford classification of learning styles. The responses of each student ranging from 'very strong,' 'strong', 'moderate', and 'low' preference towards activist, theorist, reflector and pragmatist learning styles were compiled. The two groups were compared using SPSS version 17, using Fisher's exact test and the chi-square test. A p-value of $lt; 0.05 was considered significant. Preferences for all four learning styles were present in both groups. The results reveal an overall statistically significant difference in the 'very strong' preference in learning styles between the two study groups (p=0.002). Among the undergraduate students, 45% had a very strong preference for being an activist, whereas in postgraduate students, 38% had very strong preference for reflector, and 35% for theorist. This was statistically significant for activist, and reflector, and attained a p-value of learning style was pragmatist in both undergraduate and postgraduate students. Diversity of learning styles at undergraduate and postgraduate level of medical education calls for multiplicity of instructional and assessment modalities to match them. The learning styles amongst the undergraduate medical students are different from the postgraduates. The postgraduates commonly have the reflector learning style while the undergraduates are predominantly activists and theorists.

    Absenteeism among medical students has received little attention in the literature. The aim of this study was to determine the causes of absenteeism from didactic lectures in ophthalmology and its correlation with performance in formative assessment. The attendance of 101 final year medical students for lectures in ophthalmology was studied in three parts: terms 1, 2 and 3. Based on the attendance in all three terms, students were divided into groups I to V, where group I students had good attendance in all three terms down to group V, with very poor attendance in one or more terms. The marks scored in the first, second and third terminal theory tests were tabulated separately. Results of the second and final professional examinations were assessed for the five groups of students. Students were asked to list the causes of absenteeism in a proforma. Data were analysed by regression analysis and Chi-square test. Significance was obtained at 5% level. In each formative assessment, higher attendance was associated with better marks (p absenteeism in 62.6% of instances. Six of the 10 students who failed the ophthalmology professional examination were in groups IV and V and had failed the second professional examination as well. They were designated low achievers, as were 3 students who made several attempts to pass the second professional examination and failed in ophthalmology despite a fair-good attendance. Learner absenteeism may contribute to low achievement. However, absenteeism may be symptomatic of low achievers. Low achievers or students with learning handicaps must be identified before admission or early in the medical course and encouraged to improve their performance and thereby enhance their self-esteem. A support group of family, peers, faculty and psychologists could help.

    Research on nursing students' pain knowledge and attitudes is limited. Although emotions play a role in pain assessment, no study has examined the associations between emotional intelligence and pain knowledge and the attitudes of nursing students. This cross-sectional quantitative study aimed to address this research gap by assessing the pain knowledge and attitudes of nursing students in Hong Kong and examining associations between emotional intelligence and the pain knowledge and attitudes of nursing students. A total of 104 postgraduate nursing students (45 Year 1 students and 59 Year 3 students) completed a questionnaire that included demographic information, the Schutte Emotional Intelligence Scale (SEIS) and the Knowledge and Attitudes Survey Regarding Pain (KASRP). Data analyses included descriptive statistics, correlational analyses, chi-square test and t-tests. The pain knowledge and attitudes of both Year 1 students (M = 20.40, SD = 3.78) and Year 3 students (M = 21.36, SD = 3.15) were suboptimal, t(102) = -1.41, p = .16. Year 1 students had higher emotional intelligence (M = 122.44, SD = 8.90) than Year 3 students (M = 117.71, SD = 14.34), t(98.35) = 2.07, p = .04. For Year 1 students, emotional intelligence was negatively correlated with pain knowledge and attitudes, but the correlation was not significant (r = -.15, p = .33). For Year 3 students, emotional intelligence, pain knowledge and attitudes were negatively correlated, but the correlation was significant (r = -.31, p = .02). These results suggest that nursing students' pain knowledge and attitudes could be improved. Implications for nurse educators to enhance emotional intelligence and pain education for nursing students are discussed.

    Abstract Background: Learning style is a major consideration in planning for effective and efficient instruction and learning. Learning style has been shown to influence academic performance in the previous research. Little is known about Taiwanese students' learning styles, particularly in the field of nursing education. This purpose of this study was to identify the relationship between learning styles and academic performance among nursing students in a 5-year associate degree of nursing (ADN) program and a 2-year bachelor of science in nursing (BSN) program in Taiwan. This study employed a descriptive and exploratory design. The Chinese version of the Myers-Briggs type indicator Form M was an instrument. Data such as grade point average were obtained from the Office of Academic Affairs and the Registrar computerized records. Descriptive statistics, one-way analysis of variance and chi-square statistical analysis were used to explore the relationship between academic performance and learning style in Taiwanese nursing students. The study sample included 285 nursing students: 96 students in a 2-year BSN program, and 189 students in a 5-year ADN program. Two common learning styles were found: Introversion, sensing, thinking, and judging; and introversion, sensing, feeling, and judging. A sensing-judging pair was identified in 43.3% of the participants. Academic performance was significantly related to learning style (p learning style preferences of students can enhance learning for those who are under performing in their academic studies, thereby enhancing nursing education.

    This study aimed to determine the prevalence of addiction to social networking sites/platforms (SNS) and its comorbidity with other behavioral addiction and affective disorder among college students in Singapore. 1110 college students (age: M=21.46, SD=1.80) in Singapore completed measures assessing online social networking, unhealthy food intake and shopping addiction as well as depression, anxiety and mania. Descriptive analyses were conducted to investigate the prevalence and comorbidity of behavioral addiction and affective disorder. Chi-square tests were used to examine gender differences. The prevalence rates of SNS, food and shopping addiction were 29.5%, 4.7% and 9.3% respectively for the total sample. SNS addiction was found to co-occur with food addiction (3%), shopping addiction (5%), and both food and shopping addiction (1%). The comorbidity rates of SNS addiction and affective disorder were 21% for depression, 27.7% for anxiety, and 26.1% for mania. Compared with the total sample, students with SNS addiction reported higher comorbidity rates with other behavioral addiction and affective disorder. In general, females as compared to males reported higher comorbidity rates of SNS addiction and affective disorder. SNS addiction has a high prevalence rate among college students in Singapore. Students with SNS addiction were vulnerable to experience other behavior addiction as well as affective disorder, especially among females. Copyright © 2016. Published by Elsevier B.V.

    This study was conducted to develop and test the effects of an emotional intelligence program for undergraduate nursing students. The study design was a mixed method research. Participants were 36 nursing students (intervention group: 17, control group: 19). The emotional intelligence program was provided for 4 weeks (8 sessions, 20 hours). Data were collected between August 6 and October 4, 2013. Quantitative data were analyzed using Chi-square, Fisher's exact test, t-test, repeated measure ANOVA, and paired t-test with SPSS/WIN 18.0. Qualitative data were analyzed using content analysis. Quantitative results showed that emotional intelligence, communication skills, resilience, stress coping strategy, and clinical competence were significantly better in the experimental group compared to the control group. According to the qualitative results, the nursing students experienced improvement in emotional intelligence, interpersonal relationships, and empowerment, as well as a reduction in clinical practice stress after participation in the emotional intelligence program. Study findings indicate that the emotional intelligence program for undergraduate nursing students is effective and can be recommended as an intervention for improving the clinical competence of undergraduate students in a nursing curriculum.

    In this study we explore how students' use of an easily accessible and searchable database affects their performance in clinical simulations. We do this by comparing performance of students with and without database access and compare these to a sample of faculty members. The literature supports the fact that interactive information resources can augment a clinician's problem solving ability in small clinical vignettes. We have taken the INQUIRER bacteriological database, containing detailed information on 63 medically important bacteria in 33 structured fields, and incorporated it into a computer-based clinical simulation. Subjects worked through the case-based clinical simulations with some having access to the INQUIRER information resource. Performance metrics were based on correct determination of the etiologic agent in the simulation and crosstabulated with student access of the information resource; more specifically it was determined whether the student displayed the database record describing the etiologic agent. Chi-square tests show statistical significance for this relationship (chi 2 = 3.922; p = 0.048). Results support the idea that students with database access in a clinical simulation environment can perform at a higher level than their counterparts who lack access to such information, reflecting favorably on the use of information resources in training environments.

    The misuse of alcohol among college students remains a significant public health concern in the United States. Excessive drinking among college students has been linked to numerous negative consequences, including rape, impaired academic performance, absenteeism from work and school and damaged social relations. This study examined whether religious involvement and social support played a role in reducing the frequency of alcohol use. A non-random convenience sample of 364 students from a larger study of 760 college students-18 years old and older-were recruited over a 2 month period. The survey used in this study consisted of 124 items and collected information on areas such as substance misuse, sexual activity, use of pornography, relationships, personal religious practices, and social support. A descriptive analysis and chi-square were performed to determine if there was a relationship between frequency of alcohol use and gender, marital status, student class, GPA, religion, ethnicity and age. Linear regression was conducted to determine if social support and religious involvement were predictors of frequency of alcohol misuse. Multivariate regression analysis was used for predicting religious involvement when including social support while controlling for gender, age, ethnicity and grade. The present study revealed that religious involvement was a predictor for reduced frequency of alcohol use, while social support was not a predictor of lower frequency of alcohol use.

    Globally, stress in student nurses may have serious implications for health, absenteeism, and attrition. Despite this, there is scant research on student nurses' attitudes toward help seeking. To examine student nurses' attitudes toward stress and help-seeking. A cross-sectional questionnaire survey design was employed to gather data from 219 student nurses at two large U.K. universities. Two-sample chi-square tests and Fisher's exact tests were used to analyze categorical associations between responses. Most had experienced stress before, believed the incidence within the profession was high, and would disclose their own stress to family/friends rather than to colleagues or professional institutions. The most popular outpatient treatment choice was social support; few would choose formal advice. The most common factor influencing inpatient treatment choice was confidentiality; for many, this factor would also lead them to seek distant rather than local inpatient care. Encouragingly, most would not lose confidence in a stressed colleague. Negative attitudes toward stress and help seeking may be entrenched even before training and may have a marked influence on how/whether students seek help. Nurse employers and educators should foster more supportive and accepting attitudes toward stress in order to tackle its unwanted consequences. © 2014 Wiley Periodicals, Inc.

    Full Text Available The present study set out to investigate the differences between EAP (English for Academic Purposes students of Humanities and Engineering in terms of vocabulary strategy choice and use. One hundred and five undergraduate Iranian students (39 students from Engineering Faculty and 66 from Humanities Faculty studying at Bu-Ali Sina University Hamedan, during the academic year of 2011–2012 participated in this study. For data collection purposes, a pilot-tested factor-analyzed five-point Likert-scale vocabulary learning strategies questionnaire (VLSQ containing 45 statements was adopted. The results of independent samples t-test indicated that, overall, the two groups were not significantly different in the choice and use of vocabulary learning strategies. However, running Chi square analyses, significant differences were found in individual strategy use in 6 out of 45 strategies. That is, while Humanities students used more superficial and straightforward strategies like repetition strategy and seeking help from others, the Engineering students preferred much deeper, thought-provoking and sophisticated strategies like using a monolingual dictionary and learning vocabulary through collocations and coordinates. Further, the most and the least frequently used vocabulary learning strategies by the two groups were specified, out of which only two strategies in each category were commonly shared by both groups. The possible reasons why the results have turned out to be so as well as the implications of the study are discussed in details in the paper.

    This study sought to understand the extent to which students with severe disabilities receive assistive technology in school and out-of-school, and the relationship between receipt of assistive technology in school and post-school outcomes for these students. This study was a secondary analysis of the National Longitudinal Transition Study-2 (NLTS2) from the USA. To analyze the data in this correlational study, researchers conducted frequency distributions, Chi Square Tests of Associations, significance tests and logistic regressions. The main results suggest (a) receipt of assistive technology in school varied greatly by disability identification; (b) receipt of assistive technology post-school also varied by disability identification, but receipt was generally lower; and (c) few statistically significant post-school outcome differences existed between students who received assistive technology and those who did not. An under-utilization of assistive technology exists in practice in the USA for students with severe disabilities. Implications for Rehabilitation An under-utilization of assistive technology for secondary students and adults with severe disabilities likely exists. A need exists for improved collaboration between professionals in rehabilitation and professionals in schools to ensure continuation of needed services or aids, such as assistive technology. Additional research is needed to better understand the adult life (or post-school) outcomes of individuals with severe disabilities, factors from PK-12 schooling or post-school services that positively and negative impact those outcomes.

    Research on young adults in the general population has identified a relationship between sexual minority identification and risk for suicide. Differential rates of suicidal ideation and attempts have also been found across racial and ethnic groups. This study examined risk for suicide among university students, based on membership in one or more marginalized groups (sexual minority and racial minority identification). Data were collected from first-year college students (N = 4,345) at an urban university. Structural equation modeling was employed to model a suicidality construct, based on which a "risk for suicide" category system was derived. Chi-square and logistic regression analyses were then conducted to estimate the relationship between the background variables of interest and suicide risk. Students who identified as lesbian, gay, or bisexual (LGB) were associated with higher suicide risk than their heterosexual peers. Students of color were slightly less at risk than their heterosexual peers. However, LGB students of color were associated with elevated suicide risk relative to heterosexual peers. Results indicate that belonging to multiple marginalized groups may increase one's risk for suicide, though these effects are not simply additive. Findings highlight the complexity of the intersection between marginalized identities and suicidality.

Methods:A total of 200 serum samples were collected from undergraduate students of Nasarawa State University, Keffi, and 100μL of each serum was aseptically transferred to the specimen well of an H. pylori antigen kit (Clinotech USA). The 2 distinctive red lines apearing in the control and test regions of the kit after 10 minufes indicated positive reaction. Results:Of the 200 students sampled, 108 (54%) were seropositive. Analysis of seroprevalence of H. pylori revealed the correlation between infection prevalence and age. The infection prevalence was 45.5%among students aged 18-20, rose to the peak of 85.7%adults aged 31-40, dropped to 66.7%among those 41-50 years old, and continuously went down to 28.6%in the 51-year-old and above populaion. There was a statistically significant difference (using Chi-square) with respects to gender, age and type of infection (symptomatic or asymptomatic seropositive infection)(P<0.05). Conclucions:Community Health Personnel should be aware of this microorganism as a potential cause of illness in children. Furthermore, the mode of transmission and possible means of controlling the bacterial infection among students or a community is of public health concern and requires further study.

    To identify the relationships between energy drink consumption, nutrition knowledge, and socio-demographic characteristics in a convenience sample of student-athletes. Cross-sectional. Online survey. A total of 194 student-athletes (112 female and 82 male). Socio-demographic characteristics, knowledge of human nutrition, energy drink consumption habits. Chi-square tests of independence, independent t tests, and hierarchical regression analyses were applied. Most student-athletes in the sample (85.5%) did not consume energy drinks, but those who did tended to be male (P = .004), had lower overall knowledge of nutrition (P = .02), and had a lower grade point average (P energy drink consumption was associated with the overall nutrition knowledge score when adjusted for socio-demographic characteristics, with nonusers having greater nutrition knowledge (P = .007) than users. Student-athletes tend to refrain from energy drink use but those who use it have a tendency to have lower nutrition knowledge than do nonusers. Therefore, nutrition education targeted toward student-athletes should encompass the consumption of energy drinks because limited evidence shows the benefits of collegiate athletes consuming energy drinks.

According to search results, it was found that energy drink consumption behaviour did not change with regard to the different age. On the other hand, male college graduates compared to other types of high school, it was determined that 701 TL per month and over spenders in relation to the lower income groups consumed more energy drinks . In addition, it was found that the groups that use alcohol, smokers, coffee drinkers and undergraduate students were consumed much more energy drinks than the others. When the answers measured the energy drink consumption behaviour of the students participated in the survey were considered, it was concluded that the awareness of the energy drink consumption was not high enough.

    This case series describes a unique sonographic appearance consisting of numerous microcysts and punctate echogenic foci seen on renal sonograms of 10 adult patients receiving chronic lithium therapy. Clinically, chronic renal insufficiency was present in 6 and nephrogenic diabetes insipidus in 2. Sonography showed numerous microcysts and punctate echogenic foci. Computed tomography in 5 patients confirmed microcysts and microcalcifications, which were fewer in number than on sonography. Magnetic resonance imaging in 2 patients confirmed microcysts in each case. Renal biopsy in 1 patient showed chronic interstitial nephritis, microcysts, and tubular dilatation. The diagnosis of lithium nephropathy should be considered when sonography shows these findings.

    Mucormycosis remains a devastating invasive fungal infection, with high mortality rates even after active management. The disease is being reported at an alarming frequency over the past decades from India. Indian mucormycosis has certain unique features. Rhino-orbito-cerebral presentation associated with uncontrolled diabetes is the predominant characteristic. Isolated renal mucormycosis has emerged as a new clinical entity. Apophysomyces elegans and Rhizopus homothallicus are emerging species in this region and uncommon agents such as Mucor irregularis and Thamnostylum lucknowense are also being reported. This review focuses on these distinct features of mucormycosis observed in India.

    An oral drug delivery system using proteinoid microspheres is discussed with respect to its unique dependence on pH. It has been found that certain drugs such as insulin and heparin can be encapsulated in proteinoid spheres at stomach pH's (1-3). These spheres also dissemble at intestinal pH's (6-7) releasing the drug for absorption. Using this technique low molecular weight heparin and human growth hormone have been orally delivered successfully to several animal species. Future work has been proposed to study the interaction and binding of the specific drugs with synthesized oligopeptides.

    The aim of this study was to evaluate the relationship between smoking and socio-demographic and behavioral factors among undergraduate students in the area of health at the State University of Paraíba, Brazil. An analytical cross-sectional study was conducted with a representative sample from each of the following courses: Dentistry, Nursing, Psychology, Pharmacy, Physical Therapy and Physical Education. A total of 492 students were interviewed using a structured questionnaire. The chi-square and Fisher's Exact tests were used for statistical analysis at a 5% level of significance. Smoking prevalence was 5.7% and stress was the main reason for starting the habit (36.8%). In the multivariate analysis by logistic regression, the variables of gender, religious persuasion, semester attended in the course, and alcohol consumption were significantly associated with smoking (pstudents and smoking, the prevalence of smokers was low. Most of the variables studied revealed a correlation with smoking. Since smoking and alcohol consumption are the two major human addictions, this study suggests a bidirectional relationship between these variables.

    To identify the perception of the nursing professional identity between first and fourth grade students. A descriptive study using a questionnaire. A random sample of 50 and 51 students were selected from the first and fourth grade, respectively. The questionnaire was prepared by expert consensus, and it included a sociodemographic data register, 14 items, and two open questions. Descriptive and bivariate analyses were performed on the data, using the Chi-squared test to determine the possible differences between both grades. SPSS 22.0 statistics software was employed. The open questions were submitted to a content analysis. Statistically significant differences were found between the items related to the diversity of roles that the nursing professionals can develop within the health care system (professional and academic), and between the autonomous nature of their practices. These data were confirmed by the information obtained with the open questions. Academic training is of great importance in the process of acquiring the professional identity of future professionals in nursing, but changing the public image of the profession is the responsibility of all the social agents involved in its development.

    The Chilean Red Cross Society and the family planning association--APROFA, International Planned Parenthood Federation's affiliate, are joining forces to help prevent the spread of the acquired immunodeficiency syndrome (AIDS) and human immunodeficiency virus (HIV) infection. APROFA established a working group to study the knowledge, attitudes, and sexual behavior of students at the National Training Institute, INACAP. 7000 students were sampled in 11 Chilean cities. The study found that 36% of the females, and 77% of males were sexually active before the age of 20. Nearly 1/2 of the women and 1/5 of the men did not know that condoms could protect them against sexually transmitted diseases (STDs) and pregnancy. APROFA designed a program to increase students knowledge of AIDS, reduce promiscuity and increase knowledge of and use of condoms. In October, 1988 an educational package distributed, consisting of a training manual, slides, educational booklets, a poster, and a video of 3 films. It has proved so successful that APROFA has adapted it for community groups, educational institutions, and its youth program. APROFA/Red Cross nurses and Red Cross volunteers have participated in workshops and training with the package. The Red Cross has organized AIDS-related activities in Chile since 1986, including education campaigns, information for blood donors, and a telephone hotline to provide AIDS counseling. Goals are to target more poor areas and groups outside of society's mainstream in the next year for sex education and information on STDs.

    Full Text Available In healthy societies, physical education and sport activities carry important roles in raising individuals. Previous scientific researches point out that physical activity is very important in the development process of the children. Therefore, children need to be supported in joining planned and systematic physical education and sport activities in both family and school life, beginning at very young ages. Every possibility should be offered to the children for performing sport activities healthily in the habitat while also taking precautions. The purpose of the study is to identify the expectations of the middle-school students and the problems they encounter when attending sport activities in their family and school lives. The data was collected through a survey developed by the researchers. A descriptive method with the aim of revealing the current situation was used in the study. The population of this study consisted of 2500 students, studying in the 5th, 6th, 7th and 8th grades of the middle-school. Two middle schools from the schools within the Sakarya province were selected through a random selection method. The survey was applied to a total amount of 400 volunteer students that were selected as the sample group and studied in these schools. The SPSS 15.0 for Windows software was used for the data analysis. Frequency analysis was used in order to determine the quantity and percentage distributions of the demographic information of the participants. On the other hand, chi-square analysis was used for the comparison of the problems and expectations related to family and school life in regards to the demographic variables. The level of significance in the chi-square analysis was specified as p<0,05. As a result of the study, in relation to the family and school life, the male students were found to have more problems and expectations regarding the participation in physical education and sport activities, when compared to female students

    Buden, David

    Space reactors are designed to meet a unique set of requirements; they must be sufficiently compact to be launched in a rocket to their operational location, operate for many years without maintenance and servicing, operate in extreme environments, and reject heat by radiation to space. To meet these restrictions, operating temperatures are much greater than in terrestrial power plants, and the reactors tend to have a fast neutron spectrum. Currently, a new generation of space reactor power plants is being developed. The major effort is in the SP-100 program, where the power plant is being designed for seven years of full power, and no maintenance operation at a reactor outlet operating temperature of 1350 K.

  17. The probabilities of unique events.

    Directory of Open Access Journals (Sweden)

    Sangeet S Khemlani

    Full Text Available Many theorists argue that the probabilities of unique events, even real possibilities such as President Obama's re-election, are meaningless. As a consequence, psychologists have seldom investigated them. We propose a new theory (implemented in a computer program in which such estimates depend on an intuitive non-numerical system capable only of simple procedures, and a deliberative system that maps intuitions into numbers. The theory predicts that estimates of the probabilities of conjunctions should often tend to split the difference between the probabilities of the two conjuncts. We report two experiments showing that individuals commit such violations of the probability calculus, and corroborating other predictions of the theory, e.g., individuals err in the same way even when they make non-numerical verbal estimates, such as that an event is highly improbable.

    The human species is an outlier in the natural world. Two million years ago our ancestors were a slightly odd apes. Now we occupy the largest ecological and geographical range of any species, have larger biomass, and process more energy. Usually, this transformation is explained in terms of cognitive ability-people are just smarter than all the rest. In this paper I argue that culture, our ability to learn from each other, and cooperation, our ability to make common cause with large groups of unrelated individuals are the real roots of human uniqueness, and sketch an evolutionary account of how these crucial abilities co-evolved with each other and with other features of our life histories.

    The purpose of this study was to examine factors associated with school violence perpetration among African American youth. African American students in 7th through 12th grade (n = 7488) in schools within one Metropolitan area completed the Pride National Drug Survey. Chi square analyses revealed school violence perpetration significantly differed based on grade and prosocial behavioral involvement. Students in 7th-8th grade (54.7%) were more likely to engage in school violence in comparison to 9th-12th grade students (48.8%). Students with low prosocial behavior (52.8%) involvement were more likely than their counterparts (48.9%) to engage in school violence perpetration. Logistic regression also indicated females and 9th-12th students with low prosocial behavior involvement were significantly less likely than their counterparts to engage in school violence. Findings should be considered by health educators and prevention specialists when developing programs and efforts to prevent in school violence perpetration among African American students.

    The Consortium for Oral Health Research and Informatics (COHRI) is leading the way in use of the Dental Diagnostic System (DDS) terminology in the axiUm electronic health record (EHR). This collaborative pilot study had two aims: 1) to investigate whether use of the DDS terms positively impacted predoctoral dental students' critical thinking skills measured by the Health Sciences Reasoning Test (HSRT), and 2) to refine study protocols. The study design was a natural experiment with cross-sectional data collection using the HSRT for 15 classes (2013-17) of students at three dental schools. Characteristics of students who had been exposed to the DDS terms were compared with students who had not, and the differences were tested by t-tests or chi-square tests. Generalized linear models were used to evaluate the relationship between exposure and outcome on the overall critical thinking score. The results showed that exposure was significantly related to overall score (p=0.01), with not-exposed students having lower mean overall scores. This study thus demonstrated a positive impact of using the DDS terminology in an EHR on the critical thinking skills of predoctoral dental students in three COHRI schools as measured by their overall score on the HSRT. These preliminary findings support future research to further evaluate a proposed model of critical thinking in clinical dentistry.

    This article investigated to what extent age, use of a cochlear implant, parental hearing status, and use of sign in the home determine language of instruction for profoundly deaf children. Categorical data from 8,325 profoundly deaf students from the 2008 Annual Survey of Deaf and Hard-of-Hearing Children and Youth were analyzed using chi-square automated interaction detector, a stepwise analytic procedure that allows the assessment of higher order interactions among categorical variables. Results indicated that all characteristics were significantly related to classroom communication modality. Although younger and older students demonstrated a different distribution of communication modality, for both younger and older students, cochlear implantation had the greatest effect on differentiating students into communication modalities, yielding greater gains in the speech-only category for implanted students. For all subgroups defined by age and implantation status, the use of sign at home further segregated the sample into communication modality subgroups, reducing the likelihood of speech only and increasing the placement of students into signing classroom settings. Implications for future research in the field of deaf education are discussed.

    Mobile phone abuse can cause pathologic stress that may lead to addictive behavior such as Phantom Vibration Syndrome (PVS) and Phantom Ringing Syndrome (PRS). The current study aimed to determine the PVS and PRS due to mobile phone use in students of Qom University of medical Sciences in Iran. Cross-sectional study. The participants were 380 students selected by proportional stratified random sampling method in each stratum. Data were collected by a self-administered questionnaire and analyzed by descriptive and analytic statistical methods including t-test, chi square and analysis of variance. The prevalence of PVS and PRS due to mobile phones in students of medical sciences was estimated to be 54.3% and 49.3%, respectively. PVS was higher in female students than in males while the PRS was higher in male students. There was a significant relationship between PVS and using social networks such as Viber, WhatsApp, and Line. In addition, a significant association was observed between PVS and friend-finding, chatting and entertainment. Studies should be done in the future to assess the long-term complication of overusing mobile phones. In the current study, the prevalence of PVS and PRS in half of students is considerable.

    Full Text Available Forest is not only assessed for timber production, but also for public interests. It is not easy to measure the multiple functions and existence values that forests represent to local residents. The purposes of this research were to classify landscape image aspects of students using LIST (Landscape Image Sketching Technique, to know students' attributes influencing perception, and to formulate the differences of forest landscape characters. The research was conducted in three stages: landscape image survey, landscape image analysis, and forest landscape interpretation. LIST method was applied to classify landscape image aspects. Chi-square test was applied to examine the significant differences between students of Japan and Indonesia to perceive forest landscape, while cluster analysis was applied to characterize forest landscape. The results showed that 10 prominent components were detected in both countries. The only attribute influencing perception for Indonesian students was gender. Japanese students categorized forest type into needle leaf, broadleaf, and unknown forest type, while Indonesian students classified forest type into broadleaf and unknown forest type. The results of this study might be useful as a guidance for forest landscape design in Japan and Indonesia.

    To enhance successful communication, medical teachers are increasingly using teaching-learning media. To determine medical students' perception of three such media (blackboard, overhead projector, and slides), and to generate recommendations for their optimal use, a prospective questionnaire-based study was carried out among 7th semester medical students of the University College of Medical Sciences and Guru Teg Bahadur Hospital, Delhi. Students made a forced choice between: (1) The three media on 8 questions regarding their advantages and disadvantages and (2) four aspects of a lecture (teaching-learning media, topic, teacher and time of day) regarding which made the lecture most engaging. Resulting data was analysed by Chi-square and Fisher's exact tests. Chalk and blackboard was rated as best in allowing interaction and helping recall (plecture (p=0.001; 58 students, 77.3%, considered this a disadvantage). Slides were best in imparting clinical details (p=0.004), but were sleep inducing (pimportant in making the lecture engaging (pimportant. Students enjoy the slow pace and interaction allowed by blackboard, pointwise information presented by the overhead projector, and the clinical details a slide can provide. The results suggest that the lecture could best be a combination of two or more teaching-learning media. Students' interaction should be encouraged whatever the media used.

    The aim of this study was to analyze the effect of the inclusion of video triggers in conventional face-to-face lectures on the final grades of dental students in an oral biology course. The study consisted of two groups of students taking the course in two academic years at a dental school in Saudi Arabia: group 1, 2013-14 (control); and group 2, 2014-15. The total sample comprised 163 students (n=163; group 1: 71 and group 2: 92). Group 1 received lectures without any videos, whereas group 2 received lectures that included two to three videos of one to five minutes in duration with triggering effect (a video was shown every 10-15 minutes into the lecture). The final examination grades of the students were accessed retrospectively, and the data were compared with a chi-square test. The results confirmed that a higher number of students who received video triggering during lectures (group 2) performed better than their counterparts who did not receive video triggers (group 1); the difference was statistically significant (p<0.05). Among the group 2 students, 26% achieved a grade of A, and 37% achieved a grade of B. In contrast, only 7% of the group 1 students obtained a grade of A, and 31% achieved a grade of B. These results suggest that video triggers may offer an advantage over conventional methods and their inclusion in lectures can be a way to enhance students' learning.

    The advances in science and technology increasingly lead to the appearance of ethical issues and to the complexity of care. Therefore, it is important to define the ethics position of students studying in health departments so that high quality patient care can be achieved. The aim of this study was to examine the ethics position of the students at Shool of Health of an University in western Turkey. The study design was descriptive and cross-sectional. The study population included 540 first, second, third, and fourth year students from the Departments of Nursing, Midwifery, and Rescue and Disaster Management in the 2013-2014 academic year. Data were collected with a Personal Identification Form and The Ethics Position Questionnaire. Obtained data were analyzed with Chi-square test, Confirmatory Factor Analysis, and Nested Analysis of Variance. Ethical considerations: Before conducting the research, approval was obtained from Ege University Clinical Research Ethics Committee in İzmir and written informed consent was taken from all the participants. There was no significant difference in the mean scores for the Ethics Position Questionnaire between the students in terms of years and fields of study. Although the mean scores for the subscale idealism did not differ between fields of study, the mean scores significantly differed between years of study. However, the mean scores for the subscale relativism did not differ in terms of years and fields of study. Whether students are idealistic or relativistic in terms of ethical judgment will be effective in ethical decision-making skills during patient care. Therefore, we need to define the factors that influence students' ethics position in the future. It is suggested that the courses and practices that teach students to be aware of their ethics position to create an ethical outlook can be placed in the curriculum in health schools.

    Full Text Available BACKGROUND: Students' ability of learning is influenced by study habits. Among these, the use of technologies has assumed a controversial role. The aim of this paper is to analyse studying approach, the use of technologies and how they affect study habits in a population of university students addressed by the "Sportello Salute Giovani" ("Youth Health Information Desk" questionnaire. METHODS: 16 questions referred to the approach to studying and the use of technologies (number 77-93 were analyzed. Absolute and relative frequencies were calculated. Stratification for sex, age and socio-economic status were performed and Chi square test was used to test the difference between sex, age class and socio-economic groups. RESULTS: 99.7% of students declared to have at least one mobile phone and 68.7% to use smartphones, i-phones and i-pads. Males (20.9% vs 14.9% female, p < 0.05, older students (31.7% among 25-30 years old students vs 21.3% among 18-21 years old, p < 0.05 and students with the highest socio-economic level (87.8% vs 54.2% of the lowest seem more likely to use digital technologies/Internet for educational purposes. CONCLUSION: Our survey revealed that most college students still prefer approach the study using books instead of digital tools, but this attitude is conflicting with how many hours they use computers and surf Internet per weeks. Therefore, further studies are needed to understand better technology influence on study habits and its implication on health.

    Objectives Bruxism can result in temporomandibular disorders, oral pain, and tooth wear. However, it is unclear whether bruxism affects malocclusion. The aim of this study was to examine the association between self-reported bruxism and malocclusion in university students. Methods Students (n = 1503; 896 men and 607 women) aged 18 and 19 years were examined. Malocclusion was defined using a modified version of the Index of Orthodontic Treatment Need. The presence of buccal mucosa ridging, tooth wear, dental impression on the tongue, palatal/mandibular torus, and the number of teeth present were recorded, as well as body mass index (BMI). Additional information regarding gender, awareness of bruxism, orthodontic treatment, and oral habits was collected via questionnaire. Results The proportion of students with malocclusion was 32% (n = 481). The awareness of clenching in males with malocclusion was significantly higher than in those with normal occlusion (chi square test, P < 0.01). According to logistic regression analysis, the probability of malocclusion was significantly associated with awareness of clenching (odds ratio [OR] 2.19; 95% confidence interval [CI], 1.22–3.93) and underweight (BMI <18.5 kg/m2) (OR 1.89; 95% CI, 1.31–2.71) in males but not in females. In subgroup analyses, the probability of crowding was also significantly associated with awareness of clenching and underweight (P < 0.01) in males. Conclusions Awareness of clenching and underweight were related to malocclusion (crowding) in university male students. PMID:25865057

    The purpose of this study was to examine effects of enneagram group counseling program on self-identification and depression in nursing college students. Three groups, categorized by how the students solve their conflicts, were selected to identify changes from the program. A quasi-experimental study with a non-equivalent control group and pre posttest design was used. Participants were assigned to the experimental group (n=30) or control group (n=33). The experimental group participated in enneagram group counseling program for 38 hours through eight sessions covering four different topics. Collected data were analyzed using Chi-square test, Fisher's exact test, t-test, and Wilcoxon signed rank test. Total self-identity score for the experimental group was significantly higher than the control group. However, there was no significant difference between the two groups for depression scores. The Assertive and Compliant groups demonstrated significant change in self-identification while the Withdrawn groups did not reveal any change. Results indicate that the enneagram group counseling program is very effective in establishing positive self-identification for nursing college students who face developmental crisis and stressful situations. It is also expected that this program would be useful to enhance the students' confidence through a deeper understanding and acceptance of themselves.

    Introduction UTI is a well known entity amongst young girls, and the majority of girls have recurrent infections within one year. Anything that disturbs the usual vaginal environment would result in conditions favouring the production of unwanted microorganisms leading to infections of this very sensitive area. Studies have shown that, there is an evident relation of UTI’s among students and practices of personal hygiene. Aim To determine association between the behavioural risk factors and UTI among nursing girls. Materials and Methods The present study was undertaken amongst unmarried nursing students of a Medical College Hospital. A predesigned pretested questionnaire was used to know the personal hygiene of students and to find out its association with UTI in the last three months. Chi-square test was used to analyse the data. Results A significant association was observed between perineal hygiene and UTI. The major risk factors of UTI identified were incorrect perineal washing technique, use of synthetic/silk innerwears, not sundrying the innerwears, improper menstrual hygiene. Conclusion There are still major gaps in the knowledge regarding causation of UTI among the nursing students. This calls for an urgent need for educational talks periodically addressing these gaps.

    The aim of this study was to examine student perceptions of the educational value of a comprehensive, multidisciplinary objective structured clinical examination (OSCE). The examination is administered after the second year of the curriculum, prior to the beginning of clinical training at the Columbia University College of Dental Medicine. The quantitative component of the study consisted of a survey administered to students who had taken the OSCE (N=78). Due to the ordinal level of data produced by the Likert-scale survey, statistical analysis was performed through calculation of the median and interquartile range (IQR). Overall, student perceptions of the educational value of the OSCE, as measured using a five-point scale (1=strongly disagree to 5=strongly agree) were positive, demonstrating students' agreement that the exam required the ability to think critically and problem-solve (median=4, IQR=1), assessed clinically relevant skills (median=5, IQR=1), and was a learning experience (median=5, IQR=1). A statistically significant chi-square value (pOSCE was an authentic assessment that required integration and application of knowledge.

    Historically, sexual assault is a common issue in Turkey. As doctors are one of the steps to help sexually assaulted women, medical students should have basic knowledge of and sensitivity regarding this subject. Another common women's public health issue is induced abortion. In countries where access to abortion is restricted, there is a tendency towards unhealthy abortion. The aims of this study are: (1) to determine the attitudes and opinions of Marmara University Medical Faculty students about sexual assault against women and induced abortion and (2) to propose an educational program for medical students about sexual assault and abortion. Cross-sectional study. The questionnaires were self-administered and the data were analyzed using SPSS v.15.0. First, the descriptive statistics were analyzed, followed by Chi-square for contingency tests assessing differences in attitudes toward sexual assault and induced abortion by factors such as gender and educational term. Differences were considered statistically significant at p0.05). Although there was no significant difference regarding the extent of punishment by victim's status as a virgin, 21.3% (n=63) agreed that punishment should be more severe when the victim was a virgin. About 40.7% (n=120) agreed that the legal period of abortion in Turkey (10 weeks) should be longer. The majority (86.1%, n=255) agreed that legally prohibiting abortions causes an increase in unhealthy abortions. An educational program on these issues should be developed for medical students.

    Full Text Available Abstract A cross-sectional population-based study using questionnaire and anthropometric data was conducted on 968 university students of São Luís, Brazil, from which 590 showed up for blood collection. In the statistical analysis the Student t-test, Mann-Whitney and chi-square tests were used. The prevalence of metabolic syndrome by the Joint Interim Statement (JIS criteria was 20.5%, almost three times more prevalent in men (32.2% than in women (13.5% (P < 0.001. The prevalence of insulin resistance was 7.3% and the prevalence of low HDL-cholesterol was high (61.2%, both with no statistically significant differences by sex. Men showed a higher percentage of smoking, overweight, high blood pressure, high blood glucose and increased fasting hypertriglyceridemia. Women were more sedentary. University students of private institutions had higher prevalences of sedentary lifestyle, obesity, abdominal obesity, elevated triglycerides and metabolic syndrome than students from public institutions. High prevalences of metabolic syndrome, insulin resistance and other cardiovascular risk factors were found in this young population. This suggests that the burden of these diseases in the future will be increased.

    CYP1B1, a recently described dioxin inducible oxidoreductase, is a member of the cytochrome P450 superfamily involved in the metabolism of estradiol, retinol, benzo[a]pyrene, tamoxifen, melatonin, sterols etc. It plays important roles in numerous physiological processes and is expressed at mRNA level in many tissues and anatomical compartments. CYP1B1 has been implicated in scores of disorders. Analyses of the recent studies suggest that CYP1B1 can serve as a universal/ideal cancer marker and a candidate gene for predictive diagnosis. There is plethora of literature available about certain aspects of CYP1B1 that have not been interpreted, discussed and philosophized upon. The present analysis examines CYP1B1 as a peculiar gene with certain distinctive characteristics like the uniqueness in its chromosomal location, gene structure and organization, involvement in developmentally important disorders, tissue specific, not only expression, but splicing, potential as a universal cancer marker due to its involvement in key aspects of cellular metabolism, use in diagnosis and predictive diagnosis of various diseases and the importance and function of CYP1B1 mRNA in addition to the regular translation. Also CYP1B1 is very difficult to express in heterologous expression systems, thereby, halting its functional studies. Here we review and analyze these exceptional and startling characteristics of CYP1B1 with inputs from our own experiences in order to get a better insight into its molecular biology in health and disease. This may help to further understand the etiopathomechanistic aspects of CYP1B1 mediated diseases paving way for better research strategies and improved clinical management.

    The aim of this study was to use the Hiroshima University - Dental Behavioral Inventory (HU-DBI) to compare oral health attitudes and behavior of dental and civil engineering students in Colombia. The HU-DBI's survey consisting of twenty dichotomous responses (agree-disagree) regarding tooth brushing, was completed at University Antonio Narino for the dental students and the University of Cauca for the civil engineering students. The Spanish version of the HU-DBI questionnaire was taken by 182 of 247 dental students and 411 of 762 engineering students. The data was-statistically analyzed by the chi-square test and backward logistic regression. Compared to the engineering students, the dental students were more likely to agree with questions such as "I am bothered by the color of my gums"(OR = 2.2, 95% CI: 1.3-3.7),"I think I can clean my teeth well without using toothpaste" (OR = 3.0, 95% CI: 1.5-5.9), "I have used a dye to see how clean my teeth are" (OR = 2.9, 95% CI: 1.9-4.3), and "I have had my dentist tell me that I brush very well" (OR = 2.0, 95% CI: 1.3-3.1). The dental education curriculum in a dental school compared to a civil engineering school in Colombia indicated that a three-phase curriculum in didactics and clinics increased oral health attitudes and behavior from entry to graduation.

    Breast Self-Exam (BSE) is a screening method for the early diagnosis of breast cancer in young women. However, the knowledge and applications of the students related to Breast Self-Exam (BSE) are insufficient. This study aims to investigate the knowledge, application and health beliefs of the students related to BSE. This descriptive study's sample consisted of 127 third and fourth grade students in the Nursing Department. Socio-demographic Form, Breast Cancer Knowledge Form, Health Belief Model Scale and BSE Checklist were used in order to collect the data. The data were analyzed by using descriptive statistics, chi-squared test, t-test and Mann-Whitney U test. Although most of the students have knowledge about BSE, the frequency of BSE and CBE were found to be low. The fourth grade students were more confident that they applied BSE correctly and their perceived self-efficacy was higher, but their perceived susceptibility and perceived obstacles were lower (pstudents' knowledge level about BSE was moderate and their BSE proficiency was low. It was found out that there was a statistical difference between BSE knowledge level and perceived susceptibility, health motivation, perceived obstacles and perceived self-efficacy. Also, a statistical difference was found between students' being sure that they applied BSE correctly and perceived obstacles and perceived self-efficacy (pknowledge, skills, applications and health beliefs of the students regarding BSE. The curriculums should be revised in terms of breast cancer education.

    Gopalsingh, Bhagyalakshmi

    Low high school graduation rates continue to be a challenge in American public education. The pressure to meet the demands of adequate yearly progress (AYP) under the No Child Left behind Act of 2001 has led to an achievement gap in student performance between science and other core subjects, namely English, math, and social studies, on the Georgia High School Graduation Test (GHSGT). GHSGT statistics have consistently reflected a lower science pass percentage compared with other core subjects on the test. The objective of this nonexperimental, quantitative study was to analyze teacher perceptions on reasons for student science underachievement on the GHSGT. A self-developed questionnaire based on Bloom's taxonomy model was administered to 115 high school core subject teachers of a single school district. Analyses of variance (ANOVA) and chi-square tests were used to test hypotheses. Results confirmed that teachers perceived that (a) students demonstrated a low rate of proficiency in science because science demands higher cognitive skills, (b) less emphasis was placed on science because it is a non-AYP indicator, and (c) making science an AYP indicator will optimize student science achievement. Based on results, recommendations were made to promote the integration of English, math, and social studies curriculum with science curriculum to enable students to transfer learned skills and information across subjects. The potential benefits of outcome of this study include (a) providing critical insight for policy makers and educational practitioners to understand the impact of science underachievement on graduation rates, and (b) raising student science achievement to improve graduation rates.

    In the present study, we used a model of motivation grounded in self-determination theory (Deci & Ryan, 1985, 1991; Ryan & Deci, 2000a, 2000b, 2002) to examine the relationship between physical education (PE) students' motivational processes and ratings of their effort and persistence as provided by their PE teacher. Data were obtained from 394 British secondary school students (204 boys, 189 girls, 1 gender not specified; M age = 11.97 years; SD = .89; range = 11-14 years) who responded to a multisection inventory (tapping autonomy-support, autonomy, competence, relatedness, and self-determined motivation). The students' respective PE teachers subsequently provided ratings reflecting the effort and persistence each student exhibited in their PE classes. The hypothesized relationships among the study variables were examined via structural equation modeling analysis using latent factors. Results of maximum likelihood analysis using the bootstrapping method revealed the proposed model demonstrated a good fit to the data, chi-squared (292) = 632.68, p motivation positively predicted teacher ratings of effort and persistence in PE. The findings are discussed with regard to enhancing student motivation in PE settings.

    Full Text Available Abstract Background Although nursing students experience a high level of stress during their training, there has been limited research on stress and its impact on the student's physical responses, such as gastrointestinal symptoms. The aims of this study are to assess the prevalence of GI symptoms in nursing students in Korea and to examine the association between the perceived stress and GI symptoms. Methods A cross-sectional descriptive study design was used. A total of 715 students of a three-year associate degree nursing program in a Korean college participated. The Perceived Stress Scale and a GI Symptoms Questionnaire were administered through a self-reported system. Chi-square tests, Fisher's exact test, and logistic regression analysis were performed using SPSS 17.0. Results Sixty-five percent of the nursing students experienced more than one GI symptom, with 31.1% of students reporting more than three GI symptoms. Most of the nursing students complained of upper dysmotility and bowel symptoms. In addition, students who reported higher perceived stress were significantly more likely to complain of GI symptoms. Compared to nursing students with the lowest perceived stress level, the adjusted odds ratio (OR for GI symptoms in students with the highest perceived stress level was 3.52 times higher (95% CI = 2.05-6.06. Conclusions GI symptoms that are highly prevalent among nursing students are significantly associated with the perceived stress level. High perceived stress should be considered a risk factor for GI symptoms. To reduce perceived stress, stress management programs including cognitive reappraisal training are needed in nursing curriculum.

    In 2013, our institution underwent a change to the undergraduate medical curriculum whereby a clinical urology rotation became mandatory. In this paper, we evaluated the perceived utility and value of this change in the core curriculum. Third year medical students, required to complete a mandatory 1-week clinical urology rotation, were asked to complete a survey before and after their rotation. Fourth year medical students, not required to complete this rotation, were also asked to complete a questionnaire. Chi-squared and Fisher's exact test were used for data analysis. In total, 108 third year students rotated through urology during the study period. Of these, 66 (61%) completed the pre-rotation survey and 54 (50%) completed the post-rotation survey. In total, there were 110 fourth year students. Of these, 44 (40%) completed the questionnaire. After completing their mandatory rotations, students felt more comfortable managing and investigating common urological problems, such as hematuria and renal colic. Students felt they had a better understanding of how to insert a Foley catheter and felt comfortable independently inserting a Foley catheter. Importantly, students felt they knew when to consult urology and were also more likely to consider a career in urology. Compared to fourth year students, third year students felt urology was an important component to a family medicine practice and felt they had a better understanding of when to consult urology. The introduction of a mandatory urology rotation for undergraduate medical students leads to a perceived improvement in fundamental urological knowledge and skill set of rotating students. This mandatory rotation provides a valuable experience that validates its inclusion.

Data was collected, which comprised of socio-demographic details, Patient Health Questionnaire (PHQ-9, and a 22-item semi-structured questionnaire to assess personal, perceived, and help-seeking stigma. Univariate analysis and chi-square tests were used to test for association between variables. Results: Overall prevalence of depression was found to be 64%. Highest level of depression was seen in first year. Moderate to severe depression was found in 26.6% students. 73.3% students felt that having depression would negatively affect their education, and 52.3% saw depression as a sign of personal weakness. Females more strongly believed that students would not want to work with a depressed student (50.9% v/s 36.2% and that if depressed, they would be unable to complete medical college responsibilities (61.9% v/s 44.1%. With increasing academic year, there was increase in stigma about disclosing depression to friends (P = 0.0082 and increase in stigma about working with a depressed student (P = 0.0067. Depressed students felt more strongly than non-depressed students on 10 items of the stigma questionnaire. Conclusions: High stigma exists among students about the causation of depression, and there exists an environment in which students discriminate fellow colleagues based on the presence of depression. This raises need for increasing awareness and support from peers and faculty.

This research on education included semi-structured interviews and film recordings of interns discussing 10 clinical cases. A sample of 16 interns analyzed cases presented on a notebook computer with a webcam. They were instructed to verbalize all their thoughts on the procedures they would use. The film recordings and transcripts of the interviews were analyzed. Quantitative data was evaluated using Yates' chi-squared test and speech analysis was used to evaluate the transcripts. The theme worked on in the practice of reasoning was: the student's perceptions of their clinical practice. Of the 160 diagnoses, 57% were done with analytical reasoning and 43% with non-analytical reasoning. The hypothetical deductive method was employed by 31% of the interns and the inductive method was employed by 69%. The diagnostic accuracy was 81% correct for easy cases and 85% correct for difficult cases. We observed two empirical categories: the cognitive universe of the student and the patient's context.

    This study examined the association between stress-related coping strategies and Internet addiction and the moderating effect of depression in a sample of Taiwanese college students. A total of 500 college students (238 men and 262 women) participated in this study. Internet addiction was assessed using the Chen Internet Addiction Scale. Participants' stress coping strategies and depressive symptoms were measured using the Coping Orientation to Problems Experienced and the Beck Depression Inventory-II, respectively. We used t and chi-square tests to examine differences in demographic characteristics, depression, and stress coping strategies between participants with and without Internet addiction. Significant variables were used in a logistic regression model to examine the association between stress coping strategies and Internet addiction and the moderating effect of depression on the association. Results indicated that use of restraint coping was negatively associated with Internet addiction (odds ratio [OR]=0.886, 95% confidence interval [CI]: 0.802-0.977), whereas denial (OR=1.177, 95% CI: 1.029-1.346) and mental disengagement (OR=2.673, 95% CI: 1.499-4.767) were positively associated with Internet addiction. Depression had a moderating effect on the association between denial and Internet addiction (OR=0.701, 95% CI: 0.530-0.927). Stress coping strategies and depression are important factors to evaluate when developing intervention programs targeting college undergraduate students with Internet addiction.

    To study the extent of Internet addiction (IA) and its association with depression in Thai medical students. A cross-sectional study was conducted at Faculty of Medicine, Ramathibodi Hospital. Participants were first- to fifth-year medical students who agreed to participate in this study. Demographic characteristics and stress-related factors were derived from self-rated questionnaires. Depression was assessed using the Thai version of Patient Health Questionnaire (PHQ-9). A total score of five or greater derived from the Thai version of Young Diagnostic Questionnaire for Internet Addiction was classified as "possible IA". Then chi-square test and logistic regression were used to evaluate the associations between possible IA, depression and associated factors. From 705 participants, 24.4% had possible IA and 28.8% had depression. There was statistically significant association between possible IA and depression (odds ratio (OR) 1.92, 95% confidence interval (CI): 1.34-2.77, P-value Internet use (95% CI: 1.04-2.38, P-value = 0.031). Academic problems were found to be a significant predictor of both possible IA and depression. IA was likely to be a common psychiatric problem among Thai medical students. The research has also shown that possible IA was associated with depression and academic problems. We suggest that surveillance of IA should be considered in medical schools.

    The purpose of this research was to examine the medical students' personality with stress and developmental level. The study explored three overarching topics: How are medical students' personality types reflected in an enneagram? Are there any differences between subtypes of stress points? How are the students' developmental levels by gender, academic level, and enneatypes? The subjects were 414 medical students in three Korean medical schools. Enneagram Personality Types Inventory (Korean version) was used. These enneatypes were divided into four subtypes: centers of intelligence, hornevian triads, self-consciousness, and harmonic group. Enneatypes and stress points were analyzed statistically by frequency and percentage of enneatypes, chi-square test, and ANOVA. Distribution of enneatypes; type 9 was the most frequent class (n=136, 32.9%). Types 1, 3, 4, and 9 had more disintegrated students than other types (chi2=59.2, p=0.000). Subtype analysis; in body-centered type more students were disintegrated than integrated or mediocre (chi2=25.8, p=0.000). In behavior patterns, aggressive and passive types showed more disintegration (chi2=25.2, p=0.000), and in self-consciousness groups only inner order types showed integration (chi2=19.3, p=0.001). In harmonic group, positive outlook types contained the most disintegrated students (chi2=20.5, p=0.000). Majority of medical students were in disintegrated developmental status. A program should be developed for students to know their ego-identity plainly and overcome their disintegration, based on their enneatypes. Such a program will help students improve their ways of thinking or their behavior and become more secure.

    Full Text Available Abstract Background In Nepal, Emergency Contraception (EC could play a critical role in reducing unintended pregnancies, but very few people aware about it. This paper aims to investigate the level of awareness and factors influencing awareness of EC among college students. Methods A cross-sectional study was carried out in April-May 2006. Structured self-administered questionnaires were administered to 1,137 college students (573 males and 564 females in Kathmandu valley. The association between awareness of EC and the explanatory variables were first assessed in bivariate analysis using the Chi-square test. The associations were further explored using a multivariate logistic analysis. Results Only about two-thirds of college students (68% had ever heard about EC. Bivariate analysis shows that males were more aware (72% of EC than were females (64%. Similarly, the awareness level was significantly higher among younger, unmarried youth who were from outside Kathmandu Valley, who lived with friends, and who had received reproductive health (RH education in school/college. The study also found that students' sex, permanent place of residence (district, and RH education are significant predictors of awareness of EC. Males are 1.5 times more likely to be aware of EC compared to females. Furthermore, students who lived in Kathmandu Valley were 41% less likely to be aware of EC than were students from outside Kathmandu Valley. On the other hand, those students who received RH education in school/college were almost nine times more likely to be aware of EC compared to those who did not receive such education. Conclusion Awareness of the EC is low among college students in Nepal. Health education initiatives should target students as they are more likely to be sexually active. There is a need to further educate students about EC which can help to reduce unintended pregnancies, many of which result in unsafe abortion and take a large toll on women

    A questionnaire study was conducted among dental students in Central India. The study population included 264 dental students, who voluntarily completed a questionnaire, comprising of 16 close ended questions. There were 9 questions to judge knowledge and 5 questions for attitude assessment towards global oral health course. Two additional questions were included to assess the willingness to volunteer in international setting; and also, to assess dental student's perspection on global oral health course. Chi Square test was used to compare between categorical variables. Analysis of Variance (ANOVA) was used to compare mean of knowledge and attitude scores. P value of ⩽.05 was considered significant for all statistical analysis. Eighty seven percent of the surveyed students (222) stated that they would consider volunteering their dental skills as a future dentist in international setting. Majority of the students in the present study were not aware about the global oral health status (99.2%) and theoral health care systems of industrialized and emerging economies (99.2%), had not been trained to serve underserved population (68%), had not been trained in global health ethics (70.1%) and none of the students had been trained for cultural competence in addressing international oral health issues (100%). Most of the dental students were not aware, that, WHO created basic package of oral care (63%) about the primary health care strategy (59.5%) and about the role and functions of FDI (66.7%). The majority of students expressed a desire to volunteer their professional services in international settings. However few students knew about WHO's BPOC or FDI'S role in global oral health. The findings indicate a need for global oral health course among dental students in Central India.

    The extensive use of computers as medium of teaching and learning in universities necessitates introspection into the extent of computer related health disorders among student population. This study was undertaken to assess the pattern of computer usage and related visual problems, among University students in Ajman, United Arab Emirates. A total of 500 Students studying in Gulf Medical University, Ajman and Ajman University of Science and Technology were recruited into this study. Demographic characteristics, pattern of usage of computers and associated visual symptoms were recorded in a validated self-administered questionnaire. Chi-square test was used to determine the significance of the observed differences between the variables. The level of statistical significance was at P visual problems reported among computer users were headache - 53.3% (251/471), burning sensation in the eyes - 54.8% (258/471) and tired eyes - 48% (226/471). Female students were found to be at a higher risk. Nearly 72% of students reported frequent interruption of computer work. Headache caused interruption of work in 43.85% (110/168) of the students while tired eyes caused interruption of work in 43.5% (98/168) of the students. When the screen was viewed at distance more than 50 cm, the prevalence of headaches decreased by 38% (50-100 cm - OR: 0.62, 95% of the confidence interval [CI]: 0.42-0.92). Prevalence of tired eyes increased by 89% when screen filters were not used (OR: 1.894, 95% CI: 1.065-3.368). High prevalence of vision related problems was noted among university students. Sustained periods of close screen work without screen filters were found to be associated with occurrence of the symptoms and increased interruptions of work of the students. There is a need to increase the ergonomic awareness among students and corrective measures need to be implemented to reduce the impact of computer related vision problems.

    Full Text Available The aim of this study was to determine the opinions and attitudes of the freshman students in Erciyes University Faculty of Medicine towards absenteeism. It was a descriptive and cross sectional study, which was conducted in May 2015. 81% of 310 students were accessed. A questionnaire including an absenteeism attitude scale was applied to the students. For the analysis of data, Chi square and Mann Whitney U tests were used. 7.2% of students said that they always attended the theoretical lessons whereas 71.1% of them reported that they sometimes did not attend these lessons. 21.7%, on the other hand, stated that they mostly did not attend these lessons. 81.1% of the students indicated that they always attended the practical lessons. Another finding was that foreign students attended the theoretical lessons more than Turkish students. The most common suggestion made by the students for preventing absenteeism was linking the basic courses with clinical information to be used later. The mean score obtained from the absenteeism attitude scale was 54.6 ± 15.0. The mean scores obtained from necessity, responsibility and obligation subscales were 19.6 ± 5.5, 21.4 ± 6.7, and 13.6 ± 6.1, respectively. 73.5% of the students indicated that attendance should not be controlled in the Faculty of Medicine. At the end of the study it was revealed that medical students had negative attitudes towards attendance and there was a need to organize activities that would increase their motivation and prevent absenteeism.

    Full Text Available In this paper we discuss the uniqueness of supersymmetric attractors in four-dimensional N=2 supergravity theories coupled to n vector multiplets. We prove that for a given charge configuration the supersymmetry preserving axion free attractors are unique. We generalise the analysis to axionic attractors and state the conditions for uniqueness explicitly. We consider the example of a two-parameter model and find all solutions to the supersymmetric attractor equations and discuss their uniqueness.

    Full Text Available Background: Body image dissatisfaction and eating disorders are of common problems in adolescence and adulthood especially among athletes. Objective: The aim of this study was to determine the association of eating disorders and body image in athletes and non-athlete students in Qazvin University of Medical Sciences. Methods: This cross-sectional study was conducted on 226 athlete students and 350 non-athlete students of Qazvin University of Medical Sciences during 2013-2014. Students who followed a specific sport field and had participated in at least one sport event were considered as athlete students. All athlete students were entered the study by census method. Non-athlete students were selected among students who had not any exercise activity and by random sampling method. Data were collected through demographic questionnaire, Eating Attitudes Test (EAT-26, and Multidimensional Body-Self Relations Questionnaire (MBSRQ. Data were analyzed using T-test and Chi-square test. Results: Mean age was 21.92±3.19 years and mean body mass index (BMI was 22.24±3.18 kg/m2. The frequency of eating disorders was 11.5% among the athlete students and 11.2% among the non-athlete students. Anorexia nervosa was found to be more prevalent than bulimia nervosa in both groups. The students with normal BMI had better body image perception and less eating disorders symptoms than other students. The association of age, educational level, and gender with eating disorders and body image was not statistically significant. The association of eating disorders and body image was not statistically significant. Eating disorders were more prevalent in males than females but the difference was not statistically significant. Conclusion: With regards to the results, it seems that eating disorders and body image dissatisfaction are relatively prevalent among both athletes and non-athlete students and BMI is predictor of eating disorders.

    Full Text Available Background: Attachment theory is one of the most important achievements of contemporary psychology. Role of medical students in the community health is important, so we need to know about the situation of happiness and attachment style in these students. Objectives: This study was aimed to assess the relationship between medical students′ attachment styles and demographic characteristics. Materials and Methods: This cross-sectional study was conducted on randomly selected students of Medical Sciences in Kurdistan University, in 2012. To collect data, Hazan and Shaver′s attachment style measure and the Oxford Happiness Questionnaire were used. The results were analyzed using the  SPSS software version 16 (IBM, Chicago IL, USA and statistical analysis was performed via t-test, Chi-square test, and multiple regression tests. Results: Secure attachment style was the most common attachment style and the least common was ambivalent attachment style. Avoidant attachment style was more common among single persons than married people (P = 0.03. No significant relationship was observed between attachment style and gender and grade point average of the studied people. The mean happiness score of students was 62.71. In multivariate analysis, the variables of secure attachment style (P = 0.001, male gender (P = 0.005, and scholar achievement (P = 0.047 were associated with higher happiness score. Conclusion: The most common attachment style was secure attachment style, which can be a positive prognostic factor in medical students, helping them to manage stress. Higher frequency of avoidant attachment style among single persons, compared with married people, is mainly due to their negative attitude toward others and failure to establish and maintain relationships with others.

    Context: Emergency contraception (EC) is use of drug or device to prevent pregnancy after unprotected sexual intercourse. Unlike other regular methods of contraception which are taken prior to the sexual act, EC is used after the unprotected sex. Aim: To assess the knowledge and attitude toward use of emergency contraceptives among medical students. Setting and Design: A cross-sectional questionnaire based study was conducted among all the medical students in the Government Medical College in North-West India. Subjects and Methods: A questionnaire seeking information on knowledge and attitude of undergraduate medical students was administered over a period of 4 weeks in the month of February and March 2014. Statistical Analysis: The data were entered in MS excel and expressed using percentages. Chi-square test was used as a test of statistical significance. Results: About 61.6% (247/401) of the participants were aware about the timing of use of EC. Audio visual media (76.6%; 307/401) was the most common source of information for of these medical students. Conclusions: The lack of appropriate in-depth knowledge of EC among future health care professional should alarm the medical teaching system as EC is the only method that can be used to prevent pregnancy after unprotected sex or contraceptive accident.

The aim of this cross-sectional study was to identify sleeping patterns among dental students and their association with self-reported bruxism in Riyadh Colleges of Dentistry and Pharmacy (RCsDP). Methods. A cross-sectional study was performed including 549 students (67 men and 482 women). A structured questionnaire was adopted from The PSQI (The Pittsburgh Sleep Questionnaire Index) used for data collection. It included questions which are categorized into sleeping habits, sleep-related symptoms, and additional questions concerning bruxism. This questionnaire was randomly distributed among all college preclinical and postclinical students. Sleep bruxism diagnosis was based on self-reported data. The data were analyzed using Chi-square tests through SPSS software for Windows. Results. Statistical analyses revealed significant correlations between self-reported bruxism and sleeping habits including sleep initiation (χ (2) = 22.6, p = 0.000), continuous sleep until morning (χ (2) = 19.2, p = 0.001), nighttime sleep duration (χ (2) = 20.2, p = 0.000), and length of daytime naps (χ (2) = 28.35, p = 0.000). There was an association between self-reported bruxism and sleeping-related symptoms including awakening early in the morning before the usual time without a cause (χ (2) = 16.52, p = 0.000) and increased nightmares (χ (2) = 13.7, p = 0.001). Conclusions. Poor sleeping pattern was an important factor among dental students, who reported sleep bruxism.

    Objectives. The aim of this cross-sectional study was to identify sleeping patterns among dental students and their association with self-reported bruxism in Riyadh Colleges of Dentistry and Pharmacy (RCsDP). Methods. A cross-sectional study was performed including 549 students (67 men and 482 women). A structured questionnaire was adopted from The PSQI (The Pittsburgh Sleep Questionnaire Index) used for data collection. It included questions which are categorized into sleeping habits, sleep-related symptoms, and additional questions concerning bruxism. This questionnaire was randomly distributed among all college preclinical and postclinical students. Sleep bruxism diagnosis was based on self-reported data. The data were analyzed using Chi-square tests through SPSS software for Windows. Results. Statistical analyses revealed significant correlations between self-reported bruxism and sleeping habits including sleep initiation (χ2 = 22.6, p = 0.000), continuous sleep until morning (χ2 = 19.2, p = 0.001), nighttime sleep duration (χ2 = 20.2, p = 0.000), and length of daytime naps (χ2 = 28.35, p = 0.000). There was an association between self-reported bruxism and sleeping-related symptoms including awakening early in the morning before the usual time without a cause (χ2 = 16.52, p = 0.000) and increased nightmares (χ2 = 13.7, p = 0.001).

    The objective was to evaluate the prevalence of dysmenorrhea and determine its effect on health-related quality of life (HRQoL) among a group of female university students. This cross-sectional study was conducted between 15 March and 15 April 2009 at Dumlupinar University, Kutahya, Health High School, Western Turkey. The study group included 623 female students. The severity of dysmenorrhea was determined with a 10-point visual analog scale. The Short Form-36 (SF-36) form was used to determinate HRQoL. Chi-square test, Student's t test, and logistic regression and variance analyses (ANOVA) were used for statistical analyses. The average age of the study group was 20.8 +/- 1.8 years (range 17-30). Prevalence of dysmenorrhea was found to be 72.7% and was significantly higher in coffee consumers, females with menstrual bleeding duration > or =7 days, and those who had a positive family history of dysmenorrhea when compared to the others (P coffee consumption (OR 2.084), menstrual bleeding duration > or =7 days (OR 1.590), and positive family history of dysmenorrhea (OR 3.043) were important risk factors for dysmenorrhea. Except for social functioning, role-emotional, and mental health domains, the SF-36 points received from the other domains were higher in females with dysmenorrhea (for each one P students.

    Full Text Available Background: Studies report inappropriate snack and junk food consumption patterns in children and young adults in Iran. The current survey was aimed to explore fast food consumption behaviors in high-school students based on the Theory of Planned Behavior. Materials and Methods: A cross-sectional study was done among 500 high-school students. Samples were selected based on cluster sampling method at first and simple random at second. Data were collected using a researcher-made questionnaire. To analyze, SPSS-16 and tests, including t-test, Chi-square, correlation coefficient and multiple regressions were used. Results: The monthly frequency of fast food consumption was 4.01. The TPB explained fast food use behaviors with R2 of 0.6, effectively. Results also represented that frequency of fast food consumption was meaningfully in line with behavioral intention (β = 0.60, P < 0.05 and subjective norms (β = 0.17, P < 0.05. Conclusion: It seems likely beneficial to consider important subjective norms (especially friends that may strongly effect on high-school student intention to use fast food. Also students perceived behavioral control must be increased.

    Fluorosis can manifest as dental fluorosis (seen mostly in secondary dentition), skeletal fluorosis, and systemic fluorosis. Groundwater with high fluoride concentrations, diet rich in fish and tea, indoor air-pollution, and use of fluoride toothpastes may contribute considerably to total exposure. To assess the prevalence of dental fluorosis and associated factors particularly fluoridated toothpastes, among middle school children of a resettlement colony in Delhi. This survey was conducted among the middle school students (VI th -VIII th ) studying in three government schools of Sangam Vihar, South Delhi. Students were examined for dental fluorosis by experts. A pre-structured questionnaire was used to obtain data regarding age, source of drinking water, toothpaste used, etc. Height, weight, and hemoglobin were recorded. Two repeat visits were made. Out of 432 students enrolled in these schools, 413 students were examined. Descriptive and chi-square statistics were used. Dental fluorosis was prevalent in 121 (29.3%) study subjects. It was significantly more in children of age 13 years or above, in those who used fluoridated toothpaste for dental cleaning (P=0.033) and in anemic children (Pfluorosis is very common (in about one-fourth) among the middle school children, in this resettlement colony of Delhi, various control measures e.g. discouraging the fluoridated toothpastes, educating parents about fluorosis, de-fluoridation of water in the high risk areas, etc may help to tackle this situation.

    Negative career thoughts are cognitive barriers that interfere with an individual's career decision-making and successful career development. The current study examined the effect of rational-emotive behavior therapy (REBT) on negative career thoughts of students in technical colleges in Nigeria. The study utilized a pretest-posttest control group design. One hundred and seventy-three participants from technical colleges in the Southeast zone of the country completed a measure of career thoughts at pretest, posttreatment, and follow-up: the College Students' Career Thoughts Scale. An REBT career program manual guided the intervention for 12 weeks. Data collected were analyzed using repeated-measures analysis of variance, chi-square, and t-test. Results show that the negative career thoughts of the REBT group participants were significantly reduced relative to a waitlist control group at the end of the intervention. Follow-up tests conducted after three months and six months revealed that the significant decrease in negative career thoughts of the REBT group participants was sustained. The outcomes of the current study suggest that REBT is an invaluable group therapy for assisting college students in overcoming negative thoughts associated with career choice and decision. It would be helpful if further longitudinal evaluation were implemented in Nigeria and in other countries to evaluate whether and how an REBT-based program can improve vocational maturity and vocational identity of technical college students.

    Considerable disagreements and variations exist in diagnosis and treatment planning of periodontal disease. Achieving high interrater periodontal diagnosis can prove challenging. The objectives of this study were to measure variations in periodontal diagnosis and treatment planning among predoctoral periodontics faculty members after consensus training and to compare such variation with those identified in third- and fourth-year dental students. Nine electronically stored case vignettes and survey instruments were made available to eighteen faculty members and twenty dental students under standardized conditions. A chi-square test was used to compare responses between groups, and multirater kappa tests were used to evaluate interrater agreement/reliability. Of the nine cases, only one differed between groups significantly in terms of treatment. Also, third-year students differed from fourth-year students on the diagnosis of aggressive periodontitis versus chronic periodontitis. Most respondents were able to distinguish clearly among diagnoses of chronic periodontitis, aggressive periodontitis, and gingivitis. This study established a baseline assessment of the current status of consensus after training. We will reassess variations after addressing the specific challenges identified. Programs designed and implemented to help decrease the variation in periodontal diagnosis and treatment planning among faculty members may ultimately translate into better agreement and better standardization of dental instruction.

    Background: Research shows that career choices are made as a result of preconceived ideas and exposure to a specialty. If plastic surgery is to continue to attract the best, factors that may dissuade the millennial generation medical students from pursuing plastic surgery as a career must be identified and addressed. We explored the determinants of interest in plastic surgery as a career choice amongst millennial generation medical students. Materials and Methods: A survey regarding factors considered important in choosing plastic surgery was conducted amongst final year medical students in September 2011. Participants were asked to rate their agreement or disagreement with 18 statements on a four-point Likert scale (1 = very unimportant; 4 = very important). Statistical analyses were performed using Chi-square test to compare categorical variables between male and female medical students. Values of P 3.0 was seen in all the subscales except in gender equity and life style concerns. There were statistically significant differences between male and female students in opinions of a spouse, a significant other, or family members in choosing plastic surgery P < 0.5 and my choice of plastic surgery will be influenced by my decision to have a family P < 0.5. Conclusion: Factors influencing the decision of medical students to choose plastic surgery were related to the perceived quality of life as a plastic surgeon and the ability of plastic surgeons to provide good role models for medical students. Female medical students were more concerned with gender equity and work-life balance in selecting plastic surgery compared to male medical students. PMID:27013852

    Researchers have categorized the learning styles in many ways. Kolb proposed a classification of learner's styles as convergers, divergers, assimilators and accommodators. Honey and Mumford simplified learning styles as activists, reflectors, theorists and pragmatists. Neil Fleming's VARK model (Visual, Auditory, Read/write and Kinesthetic) is also popular. This study was carried out to determine the frequency of learning styles (Honey and Mumford) of medical students and its correlation with preferred teaching methodologies and academic achievements. A total of 77 medical students of 4th year MBBS were selected through non-probability convenient sampling for this study. Honey and Mumford's learning style questionnaire, and a 2nd questionnaire to know their preference for different teaching methodologies were distributed to the students. Learning styles were identified and correlated with preferred teaching methodologies and academic achievements by Chi-square test. Mean age of the medical students was 22.75 ± 1.05 years. Twenty one (27.3%) participants were males and 56 (72.7%) females. By learning styles, 7 (9.1%) medical students were activists, 36 (46.8%) reflectors, 13 (16.9%) theorists and 21 (27.3%) were pragmatists. Out of 77 students, 22 preferred interactive lectures; 16, small group discussion; 20 problem based learning, 10 preferred demonstration on models. Only 01 students preferred one-way lecture as the best teaching methodology. No significant correlation was found between learning styles and preferred teaching methodologies and learning styles and academic scores. Most of the medical students had reflector (46.8%) and pragmatist (27.3%) learning styles. Majority preferred interactive lectures (28.57%) and problem based learning (25.98%) as teaching methodologies. Aligning our instructional strategies with learning styles of the medical students will improve learning and academic performance.

    The aim of this study was to assess the relationship between burnout, depressive symptoms and suicidal ideation in dental and dental hygiene students and to evaluate the influence of gender, programme type and year of study. Third- and fourth-year dental (DS) and first- and second-year hygiene students (DHS) completed the Patient Health Questionnaire (PHQ-9) and an abbreviated Maslach Burnout Inventory online as measures of depressive symptoms/suicidality and burnout, respectively. The statistical analyses included summary statistics and tests for intergroup comparisons (chi-square) to evaluate the influence of gender, programme type (DHS or DS) and year of study. Correlations between depression, suicidality and burnout were also conducted. A total of 32 dental hygiene and 119 dental students participated. 40% of the dental and 38% of the hygiene students met criteria for burnout. No differences were found between years or between programmes. Nine per cent of both dental and hygiene students were above the cut-off for moderate depressive symptoms, but there were no statistical differences between the third- and fourth-year dental and the first- and second-year hygiene students. Six per cent of the dental and 9% of the dental hygiene students were above the cut-off for clinically significant suicidal ideation, but there were no statistical differences between dental and hygiene students. There were no differences noted in the dental students based on gender for any of the measures. Depression was significantly associated with all three subscales of burnout. Suicidal ideation was only significantly related to the lack of personal accomplishment subscale of burnout. These findings suggest the need for introducing preventive measures for such affective states in dental and dental hygiene training programmes. © 2017 John Wiley & Sons A/S.

    To assess levels of burnout in medical students, and to explore the influence of extracurricular activities on burnout at a medical school in Saudi Arabia. This cross-sectional study was conducted with first to fourth year medical students at King Saud bin Abdulaziz University for Health Sciences (KSAU-HS) in Riyadh, Saudi Arabia. Socio-demographic, burnout level (the Maslach Burnout Inventory-Student Survey, MBI-SS) and participation in extracurricular activities data were collected using a self-administered questionnaire. Statistical analyses were performed using the Pearson's chi-square test and binary logistic regression. From the 306 medical students approached, 249 (81.4%) completed the questionnaire. The level of high burnout was 67.1% (n=167). The study revealed that the majority (62.3%, n=155) of students had high levels of cynicism, 58.6% (n=146) had high levels of emotional exhaustion, and 60.2% (n=150) had low levels of professional efficacy. Most of the students (73.5%, n=183) participated in extracurricular activities, and 112 (45%) students were organizers of extracurricular activities. No significant association was found between burnout levels and the frequency of involvement in extracurricular activities (χ(2)=2.2, df=2, p=0.333). However, students who were organizing extracurricular activities were less likely to have low professional efficacy (OR=0.51, 95% CI: 0.27- 0.96). High levels of burnout were reported at this medical school. Although the burnout level is not significantly associated with the frequency of involvement in extracurricular activities, leading and organizing extracurricular activities might result in lower levels of burnout. Therefore, improving the students' leadership skills should be considered in curriculum planning, and greater emphasis should be placed on the quality of involvement in extracurricular activities rather than the quantity.

    Full Text Available One of the transitions from adolescence to adulthood is the admission of students to a university setting. Accompanying this transition is a new-found independence which results in university students having more autonomy over their lifestyles and behaviours. The assumption in this setting is that many students are likely to engage in unhealthy and risky lifestyle behaviours which include alcohol abuse, tobacco use, physical inactivity and unhealthy dietary practices which may adversely affect their health in the long-term. In South Africa, research with regard to health and lifestyle patterns amongst both male and female young adults remains limited. The purpose of this study was, therefore, to investigate whether male and female students differed in relation to their health and lifestyles, as well as the related consequences thereof. A convenience sampling technique was used, where questionnaires were administered to 400 students at three university campuses in the Gauteng province of South Africa. An exploratory data analysis for health factors was used in order to retrieve relevant factors from a factor and regression analysis. Differences in gender were tested by using cross-tabulation for descriptive statistics and Chi-square analysis. The study found no statistically-significant differences between genders relating to the three emerging health factors, namely Gastrointestinal, Upper Respiratory Infections and Total Health Problems. However, descriptive statistics of lifestyle habits revealed that more female students exercised, smoked and binged on food than their male counterparts. It was also found that female students reported a higher incidence of stress than male students. It was concluded that university students do indeed engage in behaviours and lifestyles that place them at risk for serious health problems.

    The study purpose was to identify the sexual behavior and associated factors of Korean junior high school students. Raw data from the 2013 Korean Youth Risk Behavior Web-Based Survey were used. Among the data from 72,435 students, 36,530 junior high school students were analyzed. Complex sample frequency analysis and complex sample chi-square were used to identify the condition of sexual behavior, and complex sample logistic regression was used to examine the factors related to sexual behavior. Among the students, 3.8% responded that they had experienced sexual intercourse, and the prevalence of sexual intercourse was higher among male students (5.0%) compared to female students (2.5%). Among male students, those who had the following were more likely to have had sexual intercourse: perceived high economic status, living with a relative, experience with a partti-me job, a foreign father, experience with smoking and drinking during the past month, experience with drug use, and depression during the past 12 months. Among the female students who were more likely to have had sexual intercourse, the following were ascertained: higher grades, perceived high economic status, living with a relative or in childcare facilities, experience with a part-time job, a foreign father or mother, experience with smoking and drinking during the past month, and experience with drug use. The results suggest that it is important to develop a comprehensive approach program not only focused on sexual behavior but also including mental health or other health behaviors to effectively reduce the likelihood of sexual intercourse among Korean junior high school students.

    Full Text Available Introduction: Aphthous stomatitis is very common, affecting about 20-60% of the normal individuals to some degree. Although its etiology is not well-understood, it is multifactorial, and stress could be one possible triggering factor. Aims: The aim was to assess the prevalence of aphthous stomatitis and its association with psychological stress in both medical and dental graduate students. Materials and Methods: A cross-sectional study was conducted in 275 medical and dental student cohorts of an educational setup in India. Data were collected using a self-administered questionnaire, information regarding psychological stress, and 1-year period prevalence of aphthous stomatitis was collected. Data analysis was done with SPSS software version 20 (Chicago Inc., IL, USA. Categorical variables were compared using Chi-square test and comparison between mean stress scores and aphthous stomatitis was done with ANOVA and binary logistic regression was done. P ≤0.05 was considered as statistically significant. Results: The prevalence of aphthous stomatitis in the study population was 78.1% and males were more commonly affected than females. Among the student cohorts, final year MBBS and final year BDS students were highly affected than others, which is statistically significant. Conclusions: Stress increases the risk of aphthous stomatitis. Stress management strategies are necessary for medical and dental graduate students.

    Straffon, Elizabeth

    The purpose of this study was to investigate factors that affect the extent of international secondary students' participation in International Baccalaureate science and mathematics courses. The factors examined were gender, home region, size, percent host culture and age of the program, and coeducational and legal status of the school. Participation in math and science subjects was determined by analyzing the level and number of courses taken by students taking International Baccalaureate exams in 2010. Chi-Square and Cramer's V analysis were used to measure the effect of categorical variables on student participation and One-Way ANOVA and Bonferroni comparison of means were used to analyze the quantitative variables. All categorical variables were statistically significant (pGPA), and the importance of significant others in career and academic decisions. Findings indicate that performance on the PSAT- Math was the most important predictor of both science and mathematics participation. Twenty students were also interviewed. Results showed the importance of several key factors. These include the role of parents in student academic and career decisions, the importance of personal interest, and the contribution of early decisions in confidence-building.

    Full Text Available Introduction: Cigarette smoking leads to harmful physical and emotional disorder. Since the family atmosphere plays an important role on nurture of children, our study was done to study perspectives of the students about the family and friends influence on cigarette smoking. Material & Methods: A cross-sectional analytical study was conducted among the residents in dormitories in Golestan University of Medical Sciences which is located in Gorgan, North of Iran in 2010. The sample size consisted all of the dormitories’ students. The data was gathered using a valid and reliable questionnaire and was analyzed by SPSS software and statistical tests including Chi-square, Logistic regression and Independent t-test. Results: Of 669 students, 538 of them filled out the questionnaires completely. 6.1% of them were smoker and 83.5% of them had experiences of cigarette smoking. The most important reason for the smoking tendency was "having a smoker friend". There were significant relationships among smoking with “age, gender, ethnicity, year of education, smoker mother and smoker friend” (P<0.05. Smoker mother (OR: 8.26, CI:1.97-34.68 and smoker friend (OR:4.21, CI:1.83-9.67 increased the chance of cigarette smoking tendency of the students. Conclusion: Cigarette smoking was more common among the students who have close smoker friends. It seems that enhance of public awareness about detrimental effects of smoking is needed.

    To study the drinking behavior and factors associated with drinking among female High School students in central Thailand. A cross-sectional study was conducted with 6,176 female students from central Thailand, who were classified into 2 groups according to their alcohol drinking practices in the past year (yes = 612, no = 5,564). Information was collected by an anonymous self-reporting questionnaire which consisted of 2 parts: socio-demographic factors, and alcohol drinking behavior during the past year from December 2007 to February 2008. Descriptive statistics, a chi-square test and multiple logistic regression were used to analyze the data. Of all these respondents 9.91% admitted to drinking alcohol. Most of the students were 15 years old or younger (61.80%). Univariate analysis revealed that socio-demographic factors such as age, educational level, residence, grade point average (GPA), having a job for earning money, and having family members with alcohol or drug problems were significantly associated with the student alcohol drinking (p educational level (OR mathayomsuksa 5 = 3.39, 95% CI = 1.55-7.41; OR mathayomsuksa 3 = 2.29, 95% CI = 1.71-3.09), residence in a private dormitory (OR = 3.32, 95% CI = 1.01-10.27) and family members with alcohol or drug problems (OR = 1.72, 95% CI = 1.43-2.08), and a GPA greater than 3 (OR = 0.71, 95% CI = 0.58-0.86) (p educational level, residence within a private dormitory and family members with alcohol or drug problems. Continuous insistence regarding the disadvantages of alcohol to risk groups would reduce the proportion of new and current drinkers.

    The aging population is a globally recognized challenge for the health care service. The growing number of older people will probably lead to increased demands for nurses working in elderly care. Clinical practice has been shown to have an impact on how student nurses perceive a particular field of nursing. To compare perceptions of the clinical learning environment in nursing homes among students considering a career in aged care or not, and to examine the difference in age, gender and previous working experience as health care assistants in elderly care between the two groups. This was a cross-sectional study using the Swedish version of the Clinical Learning Environment and Nurse Teacher evaluation scale. Consecutive sampling was performed over three semesters from September 2011 to December 2012. The survey was conducted with 183 student nurses. Mann-Whitney U-test was used to examine differences in relation to two groups namely student nurses who did or did not consider to work in elderly care. A chi-square test of independence was performed to examine the difference in age, gender and previous working experience between the two groups. The analysis leaned towards an overall positive evaluation of the clinical learning environment with more positive values for students considering a career. There were no significant differences between younger students (18-23) and older students (24-50) regarding willingness to work in elderly care or not. Neither was any significant difference displayed between students, based on gender nor for previous work experience. Age, gender and previous work experiences as health care assistants did not impact on students' willingness to work in elderly care. Future studies need to acknowledge the complexity of why student nurses choose a particular pathway in nursing by longitudinal studies following cohorts of students during the course of the nursing programme.

    Nottingham, Mary E.

    The purpose of this study was to investigate the impact of a 2-year professional development model in math and science on the self-efficacy of the teacher and its effects on teacher practice and student outcomes. Further, this study sought to incorporate the instructional use of Inquiry-Based Learning methods of Problem-Based Learning, Japanese Lesson Study, and Action Research. Additionally, this study examined the impacts of these interventions on teacher efficacy and student outcomes. Thirty-eight collaborating participants were purposefully selected by the Math and Science Teacher Academy (MASTA) project grant co-directors because of their content-focused classrooms of mathematics and science. This quasi-experimental study included mathematics and science in-service teachers working on their masters in education. The 2-year, bi-monthly professional development model included collaborating Inquiry-Based Learning communities with in-depth focus on Japanese Lesson Study, Problem-Based Learning instruction, and Action Research. A chi-square analysis was conducted by grade on the difference in passing rate from the Texas Assessment of Knowledge and Skills mathematics and science tests between the MASTA participants and the state passing average. In mathematics there were significant v differences only at grades 3 and 7 where the state passing average was significantly higher than the MASTA students' passing rate. Only at grade 5 was the MASTA students' passing rate higher than the state, but the difference was not significantly different. The science passing rate received from three grade 5 MASTA participants was compared to the state average and a chi-squared was conducted. Although the passing rate for the grade 5 science test was 6% higher for MASTA student that the state, the difference was not statistically significant. However, after analyzing the qualitative participant responses from data gathered during the 2-year MASTA grant the data clearly reflected that

    Full Text Available Introduction: Studies to understand the vocal profile of a population are important to plan collective health measures. The prevalence of vocal symptoms can be indicative of vocal disorder and must be investigated to support measures to prevent vocal diseases. Aim: To characterize vocal symptoms in college students and their possible causes, and to analyze the association between hoarseness, vocal fatigue, phlegm, and burning in the throat with the possible causes mentioned. Method: Prospective study of 517 students who answered a questionnaire about their general heath and vocal symptoms and causes. We used the study of proportions, measures of central tendency, and a chi-square test to associate the presence of symptoms and possible causes. Results: Symptoms most often mentioned: dry mouth (21%, dry throat (18.2%, phlegm (17.9%. Causes most often cited: high respiratory disease (39%, intense voice use (24%, smoking (24%. Hoarseness was associated with heavy use of voice and high respiratory disease; vocal fatigue with intense voice use, stress, and digestive problems; burning in the throat with intensive voice use, high respiratory disease, and pollution; phlegm with smoking, and upper respiratory and digestive problems. Conclusion: Not only do aspects of health and the voice interfere with its production, the external environment and habits influence the vocal symptoms of this population as well.

    Full Text Available AbstractSuicidal ideation is often an indicator of mental health problems and a major risk factor for suicide. This study aims to present the prevalence of suicidal ideation and compare students of a Portuguese university by school and gender. A total of 366 individuals from four schools completed the Suicidal Ideation Questionnaire (cut-off point ≥ 41 is significant and specific questions about lifetime and past week suicidal ideation. Frequency analysis and chi-square tests were performed. The lifetime, past year and past week prevalence of suicidal ideation was 12.6%, 10.7% and 10.7%, respectively. A higher percentage of suicidal ideators were attending the School of Human and Social Sciences, and were of the female gender. However, these variables are not significantly associated with suicidal ideation. The results obtained emphasize the need for more research and the importance of taking special precautions to help students to deal with their personal and professional contingency challenges.

    This study examined the association between alcohol-use problem severity, defined by number of DSM-IV alcohol Abuse and Dependence symptoms and frequency of alcohol use, and problem behavior engagement among Mexican students. A confidential survey was administered to 1229 students in grades 7-12 at two schools in a northern border city in Mexico. Youths were categorized into five groups based on their alcohol use frequency and symptoms of DSM-IV alcohol Abuse and Dependence, specifically: no lifetime alcohol use, lifetime alcohol use but none in the past year, past year alcohol use, one or two alcohol Abuse or Dependence symptoms, and three or more alcohol Abuse or Dependence symptoms. The association between five levels of alcohol-use problem severity and three problem behaviors, lifetime marijuana use, lifetime sexual intercourse, and past year arrest/law trouble, was examined using chi-square or Fisher's exact tests. Several alcohol-use problem severity categories were significantly different with respect to rates of lifetime marijuana use, lifetime sexual intercourse, and past year arrest/law trouble. Higher alcohol-use problem severity was associated with greater endorsement of problem behaviors. Knowing about variations in adolescent alcohol use and alcohol problems may be instrumental in determining if youths are also engaging in a range of other risk behaviors. Considering varying levels of alcohol use and alcohol problems is important for effective targeted prevention and treatment interventions.

    (1) Describe the demographic characteristics of student service members and veterans (SSM/V) who seek pastoral care for mental health support; and (2) evaluate patterns of access to mental health care providers among pastoral care users and nonusers. Respondents to the Fall 2011 National College Health Assessment who reported a history of military service and ever having sought mental health care (n = 331). Differences between groups were examined using chi-square and Student's t tests. Adjusted odds ratios were estimated using ordinal logistic regression. One-third of participants used pastoral care. Users were more likely to be male and older. No significant differences were noted for race/ethnicity, sexual orientation, or exposure to hazardous duty. Users had a greater than 6-fold increase in proportional odds of accessing multiple providers. Many SSM/V look to pastoral care for mental health support. Colleges should consider incorporating a pastoral care component into specialized health care programs provided to SSM/V.

    Introduction: The purpose of this study was to evaluate the radiographic quality of root canal fillings by fourth-, fifth-, and sixth-year undergraduate students at Tabriz Faculty of Dentistry between 2006 and 2012. Methods and Materials: A total of 1183 root canal fillings in 620 teeth were evaluated by two investigators (and in case of disagreement by a third investigator) regarding the presence or absence of under-fillings, over-fillings and perforations. For each tooth, preoperative, working and postoperative radiographs were checked. The Pearson’s chi-square test was used for statistical evaluation of the data. Inter-examiner agreement was measured by Cohen’s kappa (k) values. The level of significance was set at 0.05. Results: Total frequencies of over-filling, under-filling and perforation were 5.6%, 20.4% and 1.9%, respectively. There were significant differences between frequencies of over- and under-fillings (P<0.05). Unacceptable quality, under- and over-fillings were detected in 27.9% of 1183 evaluated canals. Conclusion: The technical quality of root canal therapies performed by undergraduate dental students using step-back preparation and lateral compaction techniques was unacceptable in almost one-fourth of the cases.

    To estimate the prevalence of Human papillomavirus (HPV) among university students and to use it as a biological marker to assess sexual behavior. A cross-sectional study was carried out between 2000 and 2001 among 194 students at Universidad Autónoma del Estado de Morelos, Mexico. A data collection instrument was applied and genital samples were taken to detect oncogenic HPV DNA. Data were analyzed using the chi-squared test and odds ratios. Overall HPV prevalence was 14.4%. Women who had had two or more sexual partners during the previous year showed a greater risk of HPV infection (OR 6.0, 95% CI 1.7-21.1), as did women who had used oral contraceptives and spermicides at their latest intercourse (OR 3.0, 95% CI 1.0-8.7). Males who consumed cocaine were at a greater risk of HPV infection (OR 7.6, 95% CI 1.3-45.1). HPV prevalence is relatively high. HPV is a reliable biological marker of sexual behavior among females. A greater sample size may be needed to assess its reliability among men.

    Hamilton, Marilyn A. L.

    Many community colleges struggle to find the best strategy to help incoming at-risk students prepare for the placement test. The purpose of this quantitative quasi-experimental study, was to answer the question as to which of 2 programs, a 2-week, face-to-face mathematics refresher program, Math Boost-Up, or an online-only program, might increase the ACCUPLACER posttest scores of incoming community college students. The study used archival data for 136 students who self-selected to either participate in the Math Boost-Up program (the experiment group), or in the online-only program (the comparison group). Knowles's theory of adult learning, andragogy, served as the theoretical framework. Spearman, Kruskal-Wallis, Mann-Whitney, and chi-square tests were used to measure the effect of 4 moderator variables (age, high school GPA, number of minutes spent in MyFoundationsLab, and number of days spent in face-to-face sessions) on the pre- and posttest scores of students in each group. The results indicated that students in the Math Boost-Up program experienced statistically significant gains in arithmetic and elementary algebra than did those students in the online-only program. The results also indicated that the 4 moderator variables affected gains in posttest scores. Additionally, the results disproved the andragogical premise that students would be self-directed and would self-select to participate in the intervention. A recommendation was that participation in the face-to-face refresher program should be mandatory. The study contributes to social change by providing evidence that short-term refresher programs could increase the scores of students on placement tests.

    Full Text Available Abstract Background Given the shortage of human resources and the launching of a new Mental Health Plan, recruitment of psychiatrists is currently a major concern in Portugal, as well as in several other countries. Medical students' attitude toward psychiatry has been pointed as a predictor of recruitment. This study aims to evaluate the medical students' perception of psychiatry before and after a clerkship, and the impact on their intention to pursue psychiatry as a future specialty option. Methods Two self-report questionnaires were administered to all 6th year students in a medical school in Lisbon, before and after a 4-weeks full-time psychiatric clerkship, in order to evaluate attitudes toward psychiatry and intention to follow psychiatry in the future. Statistical analysis included Wilcoxon and Chi-square tests. Results 153 students (60.8% female filled in both questionnaires (no dropouts. After the clerkship, there was a significant improvement regarding the overall merits of psychiatry, efficacy, role definition and functioning of psychiatrists, use of legal powers to hospitalize patients and specific medical school factors. There was also a significant increase of students decided or considering the possibility to take a residency in psychiatry. However, perceptions of low prestige and negative pressure from family and peers regarding a future choice of psychiatry remained unchanged in about one-third of the students. Conclusions The results indicate clearly that the clerkship had a favorable overall impact on the student attitude towards psychiatry, as well as in the number of students considering a future career in psychiatry. Attitudes toward psychiatry seems a promising outcome indicator of the clerkship's quality, but further research is needed in order to assess its reliability as a sound predictor of recruitment.

    Roig, Matilde E.

    Minority college students have varied learning styles and process information from distinct background and cultural perspectives, which influences their learning. Accordingly, the way faculty approach teaching affects student achievement. Few minorities are in scientific fields, with a shortage of scientists predicted. A problem exists in understanding the relationship between learning style preferences and achievement of minority college students. The purpose of the study was to investigate this relationship in adult minority students in a South Florida college's biology courses. Research questions pertained to relationships between learning style preferences, race, ethnicity and grades. This quantitative study used the online Felder-Soloman Inventory of Learning Styles with a 73% response comprised of 162 White, Black-African American, Hispanic, and Asian students. Variables included grades, race, ethnicity, and learning styles. Relative frequency analysis revealed students preferred sensing, visual and sequential learning. ANOVA analysis showed no significant differences between learning style preference and achievement, nor between race-ethnicity and grades. Chi-square analysis revealed a significant relationship between Black-African Americans and Hispanics for sensing, visual and sequential learning, but not for visual. Black-African American students had the lowest passing rate in biology courses, with Asians having the highest. Increased educator and advisor knowledge of learning styles could result in social change and educational reform from this study, through the adoption of best methods for teaching minority groups enrolled in science courses. Knowing the potential shortage of minorities in the sciences, increased achievement in science courses might encourage these students to enter into scientific careers.

    Background: The aim of this study was to evaluate knowledge, attitudes, and practices regarding infection control procedures among senior dental students. Materials and Methods: A questionnaire-based cross-sectional survey was conducted among 145 4th- and 5th-year dental students at the Faculty of Dentistry, Sana’a University, Yemen. The self-administered questionnaire was comprised of 20 open- and close-ended items regarding barrier techniques, vaccination status, infection control practices, and awareness. Data were analyzed with a Chi-square test. A P ≤ 0.05 was considered significant. Results: The response rate was 72% (145 out of 204 potential respondents). Overall, 71.7% of the students had been vaccinated for hepatitis B and only 9.5% were tested for post-hepatitis B virus immunization serology. While the vast majority (96.6%) reported always wearing gloves for all dental procedures, the use of face masks and eyewear were reported by only 53.8% and 14.0% of students, respectively, with no significant difference between genders and year of study (P > 0.05). A significantly higher percentage of 5th-year students (58.9%) showed positive attitudes toward the treatment of patients with infectious diseases, as compared to only 31.0% of 4th year students (P < 0.01). A great number of students (62%) reported non-sterile occupational percutaneous and mucous injuries while treating their patients. Conclusions: These unsatisfactory findings highlight the necessity of continued infection control education in order to improve knowledge, attitudes, and practices regarding infection control among dental students at Sana’a University.

    Educational research magazines are filled with information on learning styles and how they affect the learning process, but few studies have been conducted to specifically look at learning styles exhibited by high school science students. This project attempted to obtain a general “snapshot” of learning styles found in the high school science classroom, and then compare that to one derived from a subgroup of highly motivated science students involved in a NITARP student team. Control students (N=54) from elective science courses at four high schools (urban, suburban, and rural) were administered the Felder Learning Style (FLS) assessment and rated on Likert scales in four learning constructs: Active/Reflective, Sensing/Intuitive, Visual/Verbal, and Sequential/Global. NITARP student team members (N=7) were given the FLS before project work began, and then re-tested approximately three months later, after project work concluded. Chi Square Analysis showed no clear significant difference between the general group and the NITARP group (p = .52). Both groups tended to be very visual and sequential, but more reflective than active. The results suggest several concerns that science teachers may need to address: (1) Research shows best practice science classes often are hands on, yet a majority of students are more reflective than active; (2) Big ideas tend to be better understood by global students, but a majority are more sequential; (3) Since a majority of students are visual, information given verbally may not be very effective. Further research is indicated for these areas of discontinuity. This research was conducted as part of the NASA/IPAC Training in Archival Research Project (NITARP) and was funded by NASA Astrophysics Data Program and Archive Outreach funds.

    School bullying is the most common school violence among adolescents and has become a global concern. Little is known about the characteristics associated with bullies and victims among Jordanian students. The aim of the study was to examine student perceptions of school bullying-specifically, the characteristics of perpetrators and victims and how to stop bullying-and assess differences in perceptions between boys and girls. Cross-sectional study, using self-reported questionnaires, was employed to collect data from eighth-grade students (N = 913; 51% male) from a mixed rural and suburban area in northern of Jordan during the 2013-2014 school year. Descriptive statistics were used to summarize item responses. Chi-squared tests were performed to compare responses between the male and female students. Most of the students described a bully as one who is a coward underneath (78.9%), lacks respect for other people (70%), wants to show power (67.5%), wants to impress others (60.8%), and wants to feel superior (59.6%). Students perceived victims of bullying as having low self-esteem (68.2%), talking or sounding different than others (50.9%), shy (35%), and having no friends (27.1%). Students suggested that, to stop bullying, the victim should stand up for himself (75.4%), should become psychologically stronger (75.1%), and should involve adults (teachers, family, or others; 45.9%). There was a significant gender difference, in which boys and girls were describing victims and bullies differently. A significant percentage of students relate bullying and victimization characteristics to psychosocial characteristics and less to physical characteristics. The results offer valuable information necessary to design and implement school bullying prevention and intervention programs.

    Internet is one of the technologies of the modern era that is being extensively used around the world. It is believed that excessive Internet use can be pathological and addictive. Though, academic use of the Internet is primarily intended for learning and research, students are one of the groups at risk of Internet addiction. Due to the expanding use of Internet among the university students, this study was conducted to examine the Internet addiction and its predictors among Guilan University of Medical Sciences students. A cross-sectional study was conducted on 583 students during the first semester of 2012. A two-stage stratified random sampling was conducted and a two-part instrument was used for data collection. The first part of the instrument was consisted of questions about demographic characteristics and the second part was the Young's Internet addiction inventory. Chi-square, Kruskal-Wallis testes, Spearman correlation coefficient and ranked logistic regression were used for data analysis. About 5.7% of the students were moderately dependent to the Internet, while 44.1% were at risk for Internet addiction. Significant relationships were observed between the Internet addiction with age (P semester of studying (P = 0.009) and student residence place (P = 0.014). However, no significant relationship was observed between the internet addiction score and level of discipline, parental job status and education level or the students' accommodation. About half of the participants in this study were at risk of Internet addiction. This finding can be a warning sign for the authorities in universities to pay more attention to this issue. A wide range of education along with empowering programs may be needed to inform the university students about the advantages and disadvantages of internet and the correct manner of using it.

    Full Text Available BACKGROUND: The use of Khat leaves (Catha edulis in Jazan, southwest of KSA, is prevalent among all segments of the population. OBJECTIVE: This study was conducted to assess the prevalence and predictors of Khat chewing among intermediate and secondary school students of Jazan region. METHODOLOGY: A cross-sectional survey was conducted in late 2011 in Jazan region. A random sample of 3923 students was selected from 72 intermediate and upper secondary schools representing the different educational sectors of the region. A structured self-administered questionnaire was used for data collection. Descriptive statistics, a chi-squared test and logistic regression were performed to examine the prevalence, associations and predictors of Khat chewing. RESULT: The overall Khat chewing prevalence among students was 20.5% (95% C.I.: 19.27-21.79. The prevalence was significantly higher among males, at 33.1% (95% CI: 31.16-35.08, than among females 4.3% (95% C.I.: 3.39-5.31 ( P <0.001. Univariate analysis revealed that gender, age, academic performance, friends' smoking and Khat chewing, and students' smoking status were associated with a significantly high risk of Khat chewing ( P <0.001 for all. The multivariate logistic regression analysis suggested that the most important independent predictors of Khat chewing among the students in our sample were students' smoking status (OR = 13.02, P <0.001, friends' use of Khat (OR = 5.65, P <0.001, gender (OR = 4.62, P <0.001, and friend's use of tobacco (OR = 1.43, P <0.001. CONCLUSION: A significant percentage of students chew Khat. The abuse of Khat is significantly associated with gender, peer influence, and cigarette smoking. Intervention programs are needed to create awareness among school students and to reduce the prevalence of the habit and its unfavorable consequences.

    The purpose of this study was to identify the performance differences between two groups of Austrian dental students (one with a prior medical degree and one without a medical degree) during their dental school training and final dental licensure examination. A specific aim was to determine if having a medical degree is a predictive factor for dental students' scores on the Austrian Dental Admission Test (Austrian DAT), performance in the dental clinic, and scores on final exam. The study consisted of a retrospective analysis of 122 students (thirty-nine with a medical degree and eighty-three without a medical degree) who were enrolled in the Dental Clinic at Innsbruck Medical University, Innsbruck, Austria, between 2001 and 2006. Three performance categories were considered: Austrian DAT results, clinical performance after the first clinical year in dental school, and performance on the final dental licensure examination. Information on students' age, gender, and previous medical degree was collected from official records. Analyses with student's t-test and Pearson's chi-square test revealed that the students with a medical degree had significantly higher Austrian DAT total test scores, grade point averages after the first clinical year, and scores on the final exam. Additionally, those students had significantly better performance on the final exam in prosthodontics and oral and maxillofacial surgery. The linear regression analysis showed that a medical degree had an independent effect on average scores on the final exam, age, and Austrian DAT test scores, while gender showed no statistically significant effect. Overall, the study found that dental students with a prior medical degree had significantly higher Austrian DAT total test scores and performed significantly better in the first clinical year and on the final exam than those without a prior medical degree.

    Introduction Identifying and employing students’ learning styles could play an important role in selecting appropriate teaching methods in order to improve education. The aim of this study was to determine the relationship between the students’ final exam scores and the learning style preferences of dental students at Babol University of Medical Sciences. Methods This cross-sectional study was conducted on 88 dental students studying in their fourth, fifth, and sixth years using the visual–aural–reading/writing–kinesthetic (VARK) learning styles’ questionnaire. The data were analyzed with IBM SPSS, version 21, using the chi-squared test and the t-test. Results Of the 88 participants who responded to the questionnaire, 87 preferred multimodal learning styles. There was no significant difference between the mean of the final exam scores in students who did and did not prefer the aural learning style (p = 0.86), the reading/writing learning style (p = 0.20), and the kinesthetic learning style (p = 0.32). In addition, there was no significant difference between the scores on the final clinical course among the students who had different preferences for learning style. However, there was a significant difference between the mean of the final exam scores in students with and without visual learning style preference (p = 0.03), with the former having higher mean scores. There was no significant relationship between preferred learning styles and gender (p > 0.05). Conclusion The majority of dental students preferred multimodal learning styles, and there was a significant difference between the mean of the final exam scores for students with and without a preference for the visual learning style. In addition, there were no differences in the preferred learning styles between male and female students. PMID:27382442

    Full Text Available Abstract Background Today, medical students are introduced to patient contact, communication skills, and clinical examination in the preclinical years of the curriculum with the purpose of gaining clinical experience. These courses are often evaluated from the student perspective. Reports with an additional emphasis on the facilitator perspective are scarce. According to constructive alignment, an influential concept from research in higher education, the learning climate between students and teachers is also of great importance. In this paper, we approach the learning climate by studying both students' and facilitators' course experiences. In 2001, a new "Early Professional Contact" longitudinal strand through term 1–4, was introduced at the Sahlgrenska Academy, University of Gothenburg, Sweden. General practitioners and hospital specialists were facilitators. The aim of this study was to assess and analyse students' and clinical facilitators' experiences of the Early Professional Contact course and to illuminate facilitators' working conditions. Methods Inspired by a Swedish adaptation of the Course Experience Questionnaire, an Early Professional Contact Questionnaire was constructed. In 2003, on the completion of the first longitudinal strand, a student and facilitator version was distributed to 86 students and 21 facilitators. In the analysis, both Chi-square and the Mann-Whitney tests were used. Results Sixty students (70% and 15 facilitators (71% completed the questionnaire. Both students and facilitators were satisfied with the course. Students reported gaining iiration for their future work as doctors along with increased confidence in meeting patients. They also reported increased motivation for biomedical studies. Differences in attitudes between facilitators and students were found. Facilitators experienced a greater workload, less reasonable demands and less support, than students. Conclusion In this project, a new Early

    Temporomandibular joint disorders (TMDs) have been recognized as one of the most common causes of nondental orofacial pain. Various studies have been reported in literature regarding the relationship between prevalence of signs and symptoms of TMDs and gender, suggestive of female predilection; however, none of the studies have yet been reported to suggest the relationship between knowledge about temporomandibular joint (TMJ) and TMDs and self-awareness of its signs and symptoms. To find a relationship between the level of knowledge about TMJ and TMDs and self-awareness of its signs and symptoms. This study was designed as an institutional survey. The study sample comprised 491 undergraduate and postgraduate (PG) students, consisting of 90 males and 401 females with age ranging between 18 and 32 years. Two sets of questionnaire were distributed among the students. Statistical analysis was performed with the help of Epi Info (TM) 3.5.3, descriptive statistical analysis, test of proportion, Chi-square test, one-way analysis of variance, Tukey's test, and knowledge index. It was observed that there was a gradual increase in the level of knowledge about TMJ and TMDs and self-awareness of its signs and symptoms from the 1st year to PG students. A direct relationship exists between the level of knowledge about TMJ and TMDs and self-awareness of its signs and symptoms.

    We describe the findings from a survey assessing the beliefs regarding testing, confidentiality, disclosure, and environment of care and attitudes towards care of people with HIV/AIDS (PLHWA), in 1020, 4th and 5th year medical students, from public and private medical universities in Malaysia. A self-administered validated questionnaire based on the UNAIDS Model Questionnaire with a 5-point Likert scale (5, strongly disagree; 4, disagree; 3, neutral; 2, agree; 1, strongly agree) was used as a survey tool. The survey included demographic data and data on undergraduate training received on HIV/AIDS. Statistical significance in the demographic data and training received by respondents was evaluated using the chi-square test while the independent Student's t-test was used for comparison of means between public and private universities. A P value of <0.05 was considered statistically significant with 95% confidence interval. Our study revealed less than 20% of medical students received adequate training to care for PLHWA. They had prevalent negative beliefs regarding testing, confidentiality, disclosure and environment of care towards PLHWA although in giving care to PLHWA, their attitudes were largely positive and nondiscriminatory.

    Genetic counselor self-disclosure is a complex behavior that lacks extensive characterization. In particular, data are limited about genetic counselors' responses when patients ask them to self-disclose. Accordingly, this study investigated genetic counseling students' (n = 114) and practicing genetic counselors' (n = 123) responses to two hypothetical scenarios in which a female prenatal patient requests self-disclosure. Scenarios were identical except for a final patient question: "Have you ever had an amniocentesis?" or "What would you do if you were me?" Imagining themselves as the counselor, participants wrote a response for each scenario and then explained their response. Differences in disclosure frequency for students vs. counselors and disclosure question were assessed, and themes in participant responses and explanations were extracted via content and thematic analysis methods. Chi-square analyses indicated no significant differences in frequency of student versus counselor disclosure. Self-disclosure was significantly higher for, "Have you ever had an amniocentesis?" (78.5 %) than for, "What would you do if you were me?" (53.2 %) (p < .001). Types of self-disclosures included personal, professional, and mixed disclosures. Prevalent explanations for disclosure and non-disclosure responses included: remain patient focused and support/empower the patient. Additional findings, practice and training implications, and research recommendations are presented.

    Medical schools have a major impact on future doctors' ethics and their attitudes towards cooperation with the pharmaceutical industry. From childhood, medical students who are related to a physician are exposed to the characteristics of a medical career and learn its professional ethics not only in school but also in the family setting. The present paper sought to answer the research question: 'How does growing up with a physician influence medical students' perceptions of conflicts of interest in their relationships with industry?' An anonymous questionnaire was completed by 451 medical students from four Philadelphia medical schools and 554 medical students from Warsaw Medical University during 2013. Medical schools in these two cities were chosen because they are both university cities with similar population sizes. Students who had and who did not have a family member working as a physician were compared using chi-square analysis. Data were analysed for each country separately. For both the US and Poland, there were statistically significant differences (p pharmaceutical industry. In both groups, this difference occurred for three important dimensions: students' relationship with the pharmaceutical industry; students' views on physicians' rights to cooperate with the pharmaceutical industry; trust in the pharmaceutical industry. In the US, students related to a doctor were characterized by more restrictive opinions on all three dimensions than other students (e.g., 27.8% of the former students vs. 31.4% of the latter students thought doctors had unrestricted rights to cooperate with the industry). However, the contrary was observed in Poland: students with a physician in the family had less strict views than their colleagues (e.g., 56.8% of the former vs. 39.7% of the latter thought that doctors should have unrestricted rights of cooperation). In Poland, a former communist country, physicians transmit a more liberal approach towards collaboration with the

    Abstract: Researchers, policymakers, business, and industry have indicated that the United States will experience a future shortage of professionals in the Science, Technology, Engineering, and Mathematics (STEM) fields. Several strategies have been suggested to address this impending shortage, one of which includes increasing the representation of females and minorities in the STEM fields. In order to increase the representation of underrepresented students in the STEM fields, it is important to understand the motivational factors that impact underrepresented students' interest in STEM academics and extracurricular programs. Research indicates that greater confidence leads to greater interest and vice versa (Denissen et al., 2007). In this paper, the mathematics research team examined the role of practical research experience during the summer for talented minority secondary students studying in STEM fields. An undergraduate research mathematics team focused on the link between summer research and the choice of an undergraduate discipline. A Chi Square Statistical Test was used to examine Likert Scale results on the attitude of students participating in the 2006-2012 Center for Remote Sensing of Ice Sheets (CReSIS) Summer Research Programs for secondary students. This research was performed at Elizabeth City State University located in northeastern North Carolina about the factors that impact underrepresented students' choices of STEM related majors in college. Results can be used to inform and guide educators, administrators, and policy makers in developing programs and policy that support and encourage the STEM development of underrepresented students.

    Full Text Available Abstract Background In the world of technology, when today's student is approaching the on-line /distance learning in the open universities and doing on-line self-assessment, the classroom learning is vanishing slowly. Globally, teachers are taking efforts to improve the pedagogy by implementing effective methods to retain the classroom teaching and student attendance. The present study aims at shedding some light on the need of changing the adult education strategies (andragogy, which can effectively improve the student attendance for lectures. Methods It is an observational study, and the conceptual framework of it is based on beliefs, opinions and personal experiences of the respondents. Triangulation method is used for collecting the data. The data is achieved from three groups of concerned population who could provide valid results to support the study. It is collected by interviewing 10 senior faculty members who are/were the 'education experts' in the universities, while the main concerned groups of present educational stream, i.e. 'institution-teachers' and the 'students', were given questionnaires. 570 teacher respondents and 200 student respondents are the main participants of this study. Results As per data, it has been observed that senior faculty (90% and students (93.25% feel need of student motivation more than the institutional teachers (52.44%. P-values were obtained using Chi-Square test for testing the significance of difference between agreement and disagreement for a specific question. Conclusions In India, Universities have already sensed the need of 'teacher development programmes'. But teachers in dental colleges, demand more efforts to be taken by universities and managements in this regard and expect better educational policies to give them accessibility to prove themselves.

    Good nutrition, a balanced diet and regular physical activity are foundations of good health. Research has found that dietary patterns change dramatically following the arrival of students in a foreign country. However, nutritional status of Iranian students studying oversea has never been investigated. The objective of this study was to determine factors associated with body weight status of Iranian postgraduate students in Universiti of Putra Malaysia (UPM). A cross-sectional study was conducted to determine the body weight status of 210 Iranian postgraduate students aged between 22 and 55 years in University of Putra Malaysia. The associations between body weight status and socio demographics factors and also lifestyle factors (smoking and physical activity) were assessed. Anthropometric factors (height, weight, BMI and waist and hip circumferences) were measured. Chi-square, Spearman Rho and Pearson tests were used for data analysis. From a total of 210 postgraduate students 110 were females, and 100 males. No significant correlation was observed between smoking and BMI (P = 0.4). However, statistically significant correlations were observed between gender (P = 0.007), physical activity (P = 0.02), using protein (P = 0.005), carbohydrate (P = 0.002), fat (P = 0.001), fiber (P = 0.003), vitamin C (P = 0.04), calcium (P = 0.005), waist circumference (P = 0.02), hip circumference (P = 0.001), Waist to Hip Ratio (P = 0.002), and BMI. The nutritional behavior of university students was poor. Therefore, it is essential to encourage young people, including university students to enrich their diets with milk, beans, fruit, and vegetables to decrease the risks of nutrition related disorders.

    Introduction: Obesity is a condition in which excess body fat accumulates, which leads to various adverse effects on health, particularly cardiovascular diseases (CVDs), which reduce life expectancy and/or increase health problems. Fast food consumption is one of the factors which have been reported as a cause of obesity. Body mass index (BMI) is used to assess obesity and overweight, which can be calculated by using the formula, weight in kg, divided by square of height in metres. Aim: This study focused on the relationship of body mass index with fast food consumption, associated soft drink consumption and physical activity. Methods: Descriptive cross-sectional study was conducted in Department of Biochemistry, SBKS MI and RC, and Sumandeep Vidyapeeth. This study was approved by the ethical review board .One hundred and forty seven medical students from 1st year MBBS course were included in this study. Self-structured questionnaire was used, which contained several data like information on age, height, weight, education level. The formula used for calculating BMI was, weight in kg, divided by square of height in metres (Kg/m2). Results: In our study, out of 147 students, a total of 138 students (more than 90%) used to have fast food. Among these, a total of 47 students (34.05%) were pre-obese and obese. Out of 147 students, 87 students (59.18%) were in normal weight range, while 13 (8.84%) students were underweight. Statistical Analysis: Data was compiled in an Excel worksheet and it was analyzed for percentages and proportions. Chi-square and Pearson’s correlation test were also applied wherever they were applicable and Alpha error was set at a 5% level. Conclusion: In our study, a significant relationship was found between BMI and fast food consumption, less physical activity, and intake of soft drinks. PMID:24995170

    To determine acceptability, preferred communication medium, and other key considerations for intervention by friends, professors or resident advisors, and strangers in response to college students' references to depression on the social networking site Facebook. Facebook profiles belonging to 18- to 19-year-old students (n = 60) at a large public university were evaluated for references to depression. In-person, structured interviews assessed how students would prefer to be approached by a friend, professor or resident advisor, or stranger if that person saw displays of depression on the student's Facebook page. We coded interview transcripts for approach acceptability, communication medium, and emerging themes. We used chi-square tests to assess differences between depression displayers and non-displayers. The sample was 60% female with a mean age of 18.5 years. All students were accepting of intervention approaches by friends. Most (93%) were accepting of an approach by known adults. Approximately half would accept an approach by a stranger, but this proportion was 26% lower among those who had displayed depression references on Facebook than among non-displayers (p = .072). In-person communication was preferred for approaches made by friends and adults. E-mail or using a student's friend as an intermediary was preferred if a stranger were to intervene. In-person communication from friends or trusted adults is the preferred means for raising concerns about a student's signs of depression displays on Facebook. Programs that encourage resident advisors and peers to respond in this manner and encourage treatment may represent a way to improve access to care for depression.

    Disordered eating is prevalent among college student populations, and Orthorexia nervosa (ON) is being explored as a new type of eating disorder. There is currently no standardized ON diagnostic tool, and the majority of ON research has been conducted among European populations. The present study explored the Bratman Orthorexia Test (BOT) for ON diagnosis, and its relationship to validated tools for assessing disordered eating, body dysmorphic, and obsessive-compulsive tendencies among college students attending a western university. A convenience sample of 448 college students with a mean age of 22 years was recruited to complete an online survey that included the BOT, Eating Attitudes Test-26 (EAT-26), Body Dysmorphic Disorder Questionnaire (BDDQ), Obsessive Compulsive Inventory, Revised (OCI-R) and demographics. Spearman correlation, Mann-Whitney U, Kruskal-Wallis, chi-square, and multiple linear regressions were used for analyses. The average BOT score was 4.71, near the "health fanatic" range, with Hispanic/Latino subjects and overweight/obese students having significantly higher median BOT scores. Gender, age, and college major were not significantly associated with BOT score. Significant positive correlations were observed between total BOT and EAT-26 scores (r = .47, p < 0.01), BOT and BDDQ scores (r = .25, p < 0.01), and BOT and OCI-R scores (r = .19, p < 0.01). ON tendencies may exist among college students and Hispanic/Latino and overweight/obese students may be at increased risk. Further research is needed to determine ON risk factors among diverse student populations in order to inform prevention and treatment approaches on college campuses. Copyright © 2016 Elsevier Ltd.

    Full Text Available Entrepreneurial development is highly significant in the economic growth of a country. Not many studies were conducted on entrepreneurial motivation of physically challenged students which is the core issue researched in this paper. The study further intends to (i weigh the significant relationship between curricula and entrepreneurial motivation, (ii contrast the impact of the push and the pull factors of entrepreneurial motivation, and (iii compare the desire to be entrepreneur among the physically challenged students across curricula in select public universities. It followed the mixed approach. For sampling purpose, the study considered the physically challenged students enrolled in Dilla University and Hawassa University – two major Public Universities in South Ethiopia. Preliminary findings from Focus Group Discussion revealed that there exists significant relationship between curricula and entrepreneurial motivation. Survey was conducted with well-developed questionnaire (translated in Amharic, the National Language of Ethiopia. The responses were analyzed with the help of SPSS package by using descriptive statistics, crosstabulations, chi-square test, and other non-parametric tests such as Mann-Whitney U test and Wilcoxon W test. For the purpose of data triangulation, interviews were conducted with select participants. The study found that previous family history of entrepreneurs, and curriculum imparting entrepreneurship course had no significant impact on the desire to be an entrepreneur. Of the factors of entrepreneurial motivation, pull factors which attract towards entrepreneurship were found to be more influential than the push factors. Majority expressed the need for financial support from Government agencies. Being the first of its kind, this study has original value. It is significant to various stakeholders, viz., the ministries, the universities, the physically challenged students‟ community, and the researchers.

    The voice is the sound produced by vibration of our vocal cords and has an important role in verbal communication. A child's voice disorder may significantly impair his or her ability to be heard and understood. The purpose of this study was to determine the prevalence of voice disorders in primary school students. In this descriptive-analytical study, a total of 501 fourth through fifth grade primary school students (boys = 51.6%, girls = 48.4%) with the age range of 10-12 years were selected from nine public school systems in Tehran that were assessed in October 2013 through March 2014. Presence of a voice disorder characterized by hoarseness was identified by a dual approach including investigator screening and parent identification. We used the grade of overall dysphonia, roughness, breathiness, asthenia, and strain scale for perceptual evaluation of voice. All children were assessed with video laryngoscopy examination by an otorhinolaryngologist. The recordings were made during spontaneous speech, counting numbers, sustained utterance of the (/a/) vowel, reading a standard passage in Farsi, and the ratio of /s/ and /z/. Statistical analysis was done via chi-square test and t test. Results indicated that the prevalence of voice disorders in primary school students is 53.2%. The results indicated significant differences between gender and subjects with lesions (P = 0.00000), gender and vocal disorders (P = 0.04), and s/z ratio and type of lesion (P = 0.0002). Phonotrauma seems to play an important role in child dysphonia, with nodules as main diagnosis. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    To describe the prevalence of alcohol consumption among adolescent school students and identify its individual and contextual associated factors. The present research used data from the 2009 National School Health Survey (PeNSE), which included a sample of 59,699 9th grade students in Brazilian capitals and the Federal District. The association between regular alcohol consumption and independent explanatory variables was measured by means of the Pearson's Chi-square test, with a 0.05 significance level. The explanatory variables were divided into four groups based on affinity (sociodemographic; school and family context; risk factors; and protection factors). A multivariate analysis was carried out for each group, always adjusting for age and sex. Variables with p alcohol consumption in the preceding 30 days was independently associated with pupils aged 15 years (OR = 1.46) and over, female (OR = 1.72), white, children of mothers with higher education, studying in private school, students who had tried smoking (OR = 1.72) and drug use (OR = 1.81), with regular tobacco consumption (OR = 2.16) and those who have had sexual intercourse (OR = 2.37). The factors related to family were skipping school without parental knowledge (OR = 1.49), parents not knowing what children do in their free time (OR = 1.34), having fewer meals with their parents (OR = 1.22), reporting that parents do not care (OR = 3.05), or care little (OR = 3.39) if they go home drunk, and having suffered domestic violence (OR = 1.36). The results reinforce the importance of viewing alcohol consumption among adolescents as a complex, multifactorial and socially determined phenomenon.

    To examine the effects of a web-based nursing process documentation system on the stress and anxiety of nursing students during their clinical practice. A quasi-experimental design was employed. The experimental group (n = 110) used a web-based nursing process documentation program for their case reports as part of assignments for a clinical practicum, whereas the control group (n = 106) used traditional paper-based case reports. Stress and anxiety levels were measured with a numeric rating scale before, 2 weeks after, and 4 weeks after using the web-based nursing process documentation program during a clinical practicum. The data were analyzed using descriptive statistics, t tests, chi-square tests, and repeated-measures analyses of variance. Nursing students who used the web-based nursing process documentation program showed significant lower levels of stress and anxiety than the control group. A web-based nursing process documentation program could be used to reduce the stress and anxiety of nursing students during clinical practicum, which ultimately would benefit nursing students by increasing satisfaction with and effectiveness of clinical practicum. © 2015 NANDA International, Inc.

    Behavioral risk factors are responsible for a substantial portion of chronic disease. Educating patients is a professional responsibility of medical practitioners. However, it has been observed that physicians did not practice what they preach. To study whether medical colleges inculcate health-promoting lifestyle among medical students during their stay in medical colleges. A cross-sectional study conducted in two conveniently selected medical colleges in southern India. Fourth year MBBS students were included in the study. A pre-tested self-administered multiple choice type questionnaire was used to collect data. Information was sought on the behavioral factors, namely smoking, alcohol use, junk food consumption, and physical activity, before joining the medical college and at the time of the study. SPSS version 10.0 was used to analyze the data. Frequencies, proportions, chi-square test. Out of 176 respondents, 94 (53%) were males and 82 (47%) were females. The number of smokers had increased from 24 (13.6%) to 46 (26.1%) and the number of alcohol consumers from 34 (19.3%) to 77 (43.8%) since they joined medical college. The number of students doing any physical activity declined from 76 (43.2%) to 43 (24.4%) and their food habits became unhealthier during the same period. The study reported an increase in health-risking behavior and a decline in health-promoting behavior among medical students during their stay in medical college.

    Full Text Available Dose calculation errors constitute a significant part of prescribing errors which might have resulted from informal teaching of the topic in medical schools. Objectives: To determine adequacy of knowledge and skills of drug dose calculations in children acquired by medical students during their clinical attachment in paediatrics.Methods: Fifty two 5th year medical students of the Lagos State University College of Medicine (LASUCOM, Ikeja were examined on drug dose calculations from a vial and ampoules of injections, syrup and suspension, and tablet formulation. The examination was with a structured questionnaire mostly in the form of multiple choice questions.Results: Thirty-six (69.2% and 30 (57.7% students were taught drug dose calculation in neonatal posting and during ward rounds/ bed-side teaching, respectively. Less than 50% of the students were able to calculate the correct doses of each of adrenaline, gentamicin, chloroquine and sodium bicarbonate injections required by the patient. Dose calculation was however relatively better with adrenalin when compared with the other injections. The proportion of female students that calculated the correct doses of quinine syrup and cefuroxime suspension were significantly higher than those of their male counterparts (p<0.05 and p<0.01, respectively; Chi-square test. When doses calculated in mg/dose and mL/dose was compared for adrenalin injection and each of quinine syrup and cefuroxime suspension, there were significant differences (adrenaline and quinine, p=0.005; adrenaline and cefuroxime, p=0.003: Fischer’s exact test. Dose calculation errors of similar magnitude to injections, syrup and suspension were also observed with tablet formulation.Conclusions: LASUCOM medical students lacked the basic knowledge of paediatric drug dose calculations but were willing to learn if the topic was formally taught. Drug dose calculations should be given a prominent consideration in the undergraduate medical

    Caffeine is a commonly found ingredient in many beverages. Its main dietary source is coffee, cola drinks and in recent years, energy drinks. To compare the consumption of drinks containing caffeine (coffee, colas and energy drinks) and the reasons and circumstances under which they were drunk by middle school (junior high school) pupils and university students. Surveyed subjects were 90 middle school pupils from Warsaw and Kutno together with 100 students attending the Warsaw University of Life Sciences (SGGW). A questionnaire, designed by the authors, was used to determine the amounts, frequency and the reasons or circumstances in which coffee, colas and energy drinks were consumed. Statistics used, consisted of the Mann-Whitney U and Chi-square (chi2) tests, with significance taken as alpha drinks were found to be the most popularly consumed beverages containing caffeine; 97% pupils and 93% students. Coffee was however drunk twice less by pupils compared to students, whilst similar amounts of energy drinks were consumed by both groups; respectively 48% and 53%. Gender differences were observed for the energy drinks with young men drinking the most. Coffee and energy drink consumption also rose with age by respectively 39% and 57%. The mean caffeine intake in pupils and students were respectively estimated to be 141 and 163 mg/day(d). The reasons why these beverages were drunk varied, from drinking coffee to keeping awake and drinking cola because of its good taste. Pupils also drank energy drinks due to its taste but students because of improved mental performance and in staying awake. Drinking caffeine containing drinks by adolescents can be very variable and comes from many different sources. Thus, its intakes may be very high and so require monitoring, particularly for the youngest. Further observational studies are needed to assess the consumption of energy drinks in relation to physical activity.

    Full Text Available Background: Considering the significant role of consumers’ awareness about food labels in making healthy food choices, this study was designed to assess the knowledge, attitude and prac-tice of university students about food labeling.Methods: In this cross-sectional study, 332 students aged 18-25 yr in five different academic ma-jors (including Nutrition, Public Health, Health Services Administration, Paramedical and En-gineering were asked to complete an approved questionnaire contained fifteen questions. The chi-square test was applied to examine the differences across various major groups.Results: 89.2% of the students believed that food labels had effect on nutritional awareness. 77.4% were agreed with the usefulness of the food labels and 79.2% did not feel that nutrition claims on food label were truthful. For 84% of students, the expiry date and storage conditions information were the most important informational cues to appear on the food labels. From 47.6% of students who reported the use of nutrition facts label in their often or always shopping; only 32.3% used the information on labels to fit the food into their daily diet. Surprisingly, fatty acids were the least noteworthy items (1.9% on nutrition facts labels. Regarding students’ major, there was significant difference in their knowledge, attitude and practice about truth of the nutri-tion claims, using food labels and importance of health claims (P<0.05.Conclusion: Food labels were more useful tools for students and had an effect on their nutri-tional awareness. Designing and implementation of the educational programs in order to increase the level of knowledge about food labels is suggested.

    Introduction: Risky behaviors are those that potentially expose people to harm, or significant risk of harm, which prevent them from reaching their potential in life and which can cause significant morbidity or mortality. Objectives: The objectives of the study were to determine the overall prevalence of risky behaviors among university students; to determine the prevalence of smoking, drifting, fast driving and physical inactivity among university students; and to determine the associations between such behavior and demographic characteristics. Materials and Methods: An observational cross-sectional study conducted in three colleges. The data were randomly collected from 340 students aged 18-30 years from February to March 2015 using a self-administered questionnaire in Arabic. The data were entered using SPSS v 22.0. Mean and standard deviation were calculated for quantitative variables, and frequency and percentages were computed for categorical variables. Chi-square or Fisher's Exact test, as appropriate, were used to test for statistical significance. Results: The overall prevalence of risky behaviors (smoking, drifting, fast driving, and physical inactivity) among students was 47.35%. Overall, 28% of the students were smokers, 25.2% were involved in drifting, 60.9% reported driving fast, and 66.4% were physically inactive. The age between 18-20 years was significantly associated with higher rates of drifting, fast driving, and physical inactivity. Conclusion: The prevalence of risky behaviors among university students was high. Physical inactivity and fast driving were the most common identified risky behaviors. Increasing awareness of these risks in the youth may significantly decrease related morbidities, complications, and even mortalities. PMID:27625578

    Full Text Available This cross-sectional study aimed to determine the radiographic criteria used by final-year dental students when defining the need for restorative treatment for proximal caries, as well as investigating potentially associated factors in this therapeutic decision. A questionnaire with two schematic diagrams presenting five levels of proximal lesion penetration was administered to students attending the six private and three public dental schools in the state of Rio Grande do Sul, Southern Brazil. Absolute and relative frequencies were described and inferential statistics involving Chi-square and McNemar tests and simple logistic regression were carried out to assess variations in therapeutic decisions related to patient dentition (deciduous/permanent and gender, age and dental school (public/private. Of the 346 dental students assessed, 28.6% (99/346 indicated restorative treatment for lesions restricted to the enamel in deciduous teeth and 38.2% (132/346 indicated the same for permanent teeth, revealing a statistically significant difference (p = 0.001. Student gender and age were not associated with the therapeutic decision; however, a significant difference between dental schools was found when comparing restorative criteria in deciduous (p < 0.001 and permanent molars (p < 0.001. The odds of restorative decision in permanent teeth when the caries lesion was restricted to the enamel was 72% higher for students graduating from private schools compared to public schools (Odds Ratio: 1.72; 95% Confidence Interval: 1.03-2.90. These data demonstrate a large variation between the therapeutic decisions regarding proximal caries reported by final-year dental students and suggest that deep reflection is needed on the part of faculty in order to provide an evidence-based education.

Results: The response rate was 80% and all respondents were Arabs with 114 (57% females and 86 (43% males. Self-medication was practiced by 118 (59% students and most (88.1% of them obtained medications from pharmacies. About 21 (11% respondents self-medicated with antibiotics. Only 34 (17% and 16 (8% of respondents were aware of bacterial resistance and rational drug use respectively. The most common reasons for self-medication were seeking quick relief (134, 67%, physician′s advice of self-management (100, 50%, illness is minor (91, 45.5%. Common reasons against self-medication include risk of misdiagnosis of illness (160, 80%, risk of using the wrong medication (154, 77%, risk of adverse effects (140, 70%. Self-medication was practiced for headache or mild pain, eye and ear symptoms, gastric problems, cold, fever and allergy. Conclusion: Self-medication among non-healthcare students is common with high prevalence. Knowledge of students of reasons for and against self-medication was adequate, but awareness of respondents of rational drug use and risk of bacterial resistance in response to misuse was poor. Orientation courses/workshops directed to university students would be beneficial.

    Full Text Available Abstract Background During the last few decades, the Kingdom of Saudi Arabia (KSA experienced rapid socio-cultural changes caused by the accelerating economy in the Arabian Gulf region. That was associated with major changes in the food choices and eating habits which, progressively, became more and more "Westernized". Such "a nutritional transition" has been claimed for the rising rates of overweight and obesity which were recently observed among Saudi population. Therefore, the objectives of the current work were to 1 determine the prevalence of overweight and obesity in a sample of male college students in KSA and 2 determine the relationship between the students' body weight status and composition and their eating habits. Methods A total of 357 male students aged 18-24 years were randomly chosen from College of Health Sciences at Rass, Qassim University, KSA for the present study. A Self-reported questionnaire about the students' eating habits was conducted, and their body mass index (BMI, body fat percent (BF%, and visceral fat level (VFL were measured. Data were analyzed using SPSS statistical software, and the Chi-square test was conducted for variables. Results The current data indicated that 21.8% of the students were overweight and 15.7% were obese. The total body fat exceeded its normal limits in 55.2% of the participants and VFL was high in 21.8% of them. The most common eating habits encountered were eating with family, having two meals per day including breakfast, together with frequent snacks and fried food consumption. Vegetables and fruits, except dates, were not frequently consumed by most students. Statistically, significant direct correlations were found among BMI, BF% and VFL (P Conclusions Our findings suggest the need for strategies and coordinated efforts at all levels to reduce the tendency of overweight, obesity and elevated body fat, and to promote healthy eating habits in our youth.

To know the nutritional status of students from six schools in the province of Valencia and its degree of adherence to the Mediterranean Diet (MD.Material and methods: Cross-sectional study that included 777 students, 49.9% were boys and 50.1% girls aged between 8 and 16 years. Weight and height of each participant was determined and body mass index (BMI was calculated. From the Z-score BMI was calculated. KIDMED test was used to study the degree of adherence to the MD.Results: The prevalence of overweight was 14.5 % and 10.0% obese. A total of 53.3%, 30.1% and 16.6% of the whole sample showed a high, medium and low adherence to the MD, respectively. Age, sex and nutritional status were evaluated according to the adherence to the MD. Chi-squared analysis indicated significant association between academic course and nutritional status with the adherence to the MD. Being older and having a higher BMI supposed lower adherence to the MD.Conclusions: We confirmed that the adherence to the MD has significant association with the nutritional status of young people, worsening with increasing age. These results corroborate the need to re-learn eating habits.

    Full Text Available Aim: The purpose of this study was to find out the prevalence of temporomandibular disorder (TMD in a sample of university students and its relationship to gender, occlusion, and psychological factors. Materials and Methods: The sample comprised 196 subjects, aged 18-25 years. The TMD degree was evaluated using an anamnestic questionnaire. Morphologic occlusion was evaluated according to Angle classification (classes I, II, and III. The Hospital Anxiety and Depression Scale (HADS, a 14-item self-administered rating scale developed specifically to identify anxiety and depression in nonpsychiatric medical outpatients, was used to assess the levels of anxiety (HADSa and depression (HADSd. Statistical Analysis: The incidence of TMD level, malocclusion, anxiety, and depression in both genders was calculated as percentages. Association between TMD degree and occlusion, HADSa, and HADSd was tested using the Chi-square test. Results: According to our results, 50% of the subjects had TMD, but it was of moderate or severe degree in only 9.18% of them. No statistically significant association could be found between TMD and gender or occlusion. TMD was found to have statistically significant association with HADSa but not with HADSd. Conclusion : A high prevalence of TMD was found in this student population; however, most of the cases could be classified as mild. Of the variables studied, only HADSa had a statistically significant association with TMD.

    Full Text Available We describe the findings from a survey assessing the beliefs regarding testing, confidentiality, disclosure, and environment of care and attitudes towards care of people with HIV/AIDS (PLHWA, in 1020, 4th and 5th year medical students, from public and private medical universities in Malaysia. A self-administered validated questionnaire based on the UNAIDS Model Questionnaire with a 5-point Likert scale (5, strongly disagree; 4, disagree; 3, neutral; 2, agree; 1, strongly agree was used as a survey tool. The survey included demographic data and data on undergraduate training received on HIV/AIDS. Statistical significance in the demographic data and training received by respondents was evaluated using the chi-square test while the independent Student’s t-test was used for comparison of means between public and private universities. A value of <0.05 was considered statistically significant with 95% confidence interval. Our study revealed less than 20% of medical students received adequate training to care for PLHWA. They had prevalent negative beliefs regarding testing, confidentiality, disclosure and environment of care towards PLHWA although in giving care to PLHWA, their attitudes were largely positive and nondiscriminatory.

    Carmona Miranda, Karla

    In the last 20 years attitudes towards science and science classes in K-12 education have been an important topic of investigation due to the decreasing number of students choosing Science, Technology, Engineering and Math (STEM) related careers, and the increasing need for STEM prepared workers to cover the job demands of the future. The purpose of this study is to confirm a previously measured difference in scientific curiosity between middle school students in El Paso and in Ciudad Juarez, and to collect additional data that might tell us what the possible factors or reasons for this difference are. Our sample consists of 156 middle school students from Juarez public schools, and 448 middle school students from El Paso public middle schools. The Children's Science Curiosity Scale of Harty & Beall (1984) will be used to measure the curiosity level. Additionally, the students will be asked to respond to "Why do you like or dislike science?" Our results show that those obtained by Ortiz (2006) in a similar study persist but with a reduction of standard deviations. The percentage of students that state that they do not like science in Ciudad Juarez and El Paso are 9% and 14%, respectively. The most common reason to like science among students in Ciudad Juarez was related to the topics covered in class, and among students in El Paso was related to the experiments and hands-on activities done in class. After analyzing contingency tables with chi-squared tests and calculating the respective contingency coefficients, it is safe to say that even though relationships between the reasons to like or dislike science and country exist, these relationships are not strong. Other results, limitations, and future research also are discussed.

    Self-rated health is a brief measure for general health. It is a comprehensive and sensitive index for prediction of health in future. Due to the high internet usage in medical students, the current study designed to evaluate the self-rated health (SRH) in relationship with internet addiction risk factors in medical students. This cross sectional study conducted on 254 students of Qom University of Medical Sciences 2014. Participants selected by two stage sampling method including stratified and simple random sampling. The Young's questionnaire of internet addiction and SRH question used for data collection. Chi-square, t-test, and logistic regression used in data analysis. More than 79.9% of students reported their general health good and very good. The student's mean score of general health was higher than the average. In addition, the prevalence of internet addiction was 28.7%. An inverse significant correlation observed between SRH and internet addiction score (r=-0.198, p=0.002). Using internet for Entertainment, using private Email and chat rooms were the most important predictors of affecting to internet addiction. Moreover, internet addiction is the most predictors of SRH and increased the odds of bad SRH. The good SRH of medical students was higher than general population but in health faculty' students were lower than others. Due to the effect of internet addiction on SRH and increasing trend of internet use in medical students, as well as low age of participants, attention to psychological aspects and the job expectancy in future, can effective on increasing the good SRH.
