The elective placement is an opportunity for nursing undergraduates to independently decide where to go and what to do to widen their clinical experience. Being able to decide on and participate in an elective placement provides student nurses with a chance to work in a different area and explore personal ambitions. This reflective account examines a student nurse's experiences while on an elective placement at an eye hospital in East Jerusalem and the West Bank.

Kirkby, K. C.; Kirkby, S.

2013-12-01

Self-guided field explorations are a simple way to transform an earth science class into a more pedagogically effective experience. Previous experience demonstrated that self-guided student explorations of museum and aquarium exhibits were both extremely popular and remarkably effective. That success led our program to test an expansion of the concept to include self-guided student explorations in outdoor field settings. Preliminary assessment indicates these self-guided field explorations are nearly as popular with students as the museum and aquarium explorations and are as pedagogically effective. Student gains on post-instruction assessment match or exceed those seen in instructor-assisted, hands-on, small group laboratory activities and completely eclipse gains achieved by traditional lecture instruction. As importantly, self-guided field explorations provide a way to integrate field experiences into large enrollment courses where the sheer scale of class trips makes them logistically impossible. This expands course breadth, integrating new topics that could not be as effectively covered by the original class structure. Our introductory program assessed two models of self-guided field explorations. A walking/cycling exploration of the Saint Anthony Falls area, a mile from campus, focuses on the intersections of geological processes with human history. Students explore the geology behind the waterfalls' evolution as well as its subsequent social and economic impacts on human history. A second exploration focuses on the campus area geology, including its building stones as well as its landscape evolution. In both explorations, the goal was to integrate geology with the students' broader understanding of the world they live in. Although the explorations' creation requires a significant commitment, once developed, self-guided explorations are surprisingly low maintenance. These explorations provide a model of a simple, highly effective pedagogical tool that is

Full Text Available Background: Public speaking anxiety is a prominent problem in the college student population. The purpose of this study was to determine the effectiveness of eye movement desensitization and reprocessing on public speaking anxiety of college students. Materials and Methods: The design of research was quasi-experimental with pre-post test type, and control group. The sample consistent of 30 students with speech anxiety that selected base on available sampling and assigned randomly in experimental (N=15 and control (N=15 groups. The experimental group was treated with EMDR therapy for 7 sessions. In order to collect the data, Paul’s personal report of confidence as a speaker, S-R inventory of anxiousness was used. To analyze the data, SPSS-19 software and covariance analysis were used. Results: The multivariate analysis of covariance showed that the eye movement desensitization and reprocessing reducing public speaking anxiety. The one-way analysis of covariance for each variable shows there are significant differences in confidence of speaker (p=0.001 and physiological symptoms of speech anxiety (p=0.001 at the two groups. Conclusion: These results suggest that treatment of eye movement desensitization and reprocessing is effective on reducing physiological symptoms of speech anxiety and increasing the speaker’s confidence.

Instruction-based clinical eye-tracking study on the visual interpretation of divergence: How do students look at vector field plots?

Klein, P.; Viiri, J.; Mozaffari, S.; Dengel, A.; Kuhn, J.

2018-06-01

Relating mathematical concepts to graphical representations is a challenging task for students. In this paper, we introduce two visual strategies to qualitatively interpret the divergence of graphical vector field representations. One strategy is based on the graphical interpretation of partial derivatives, while the other is based on the flux concept. We test the effectiveness of both strategies in an instruction-based eye-tracking study with N =41 physics majors. We found that students' performance improved when both strategies were introduced (74% correct) instead of only one strategy (64% correct), and students performed best when they were free to choose between the two strategies (88% correct). This finding supports the idea of introducing multiple representations of a physical concept to foster student understanding. Relevant eye-tracking measures demonstrate that both strategies imply different visual processing of the vector field plots, therefore reflecting conceptual differences between the strategies. Advanced analysis methods further reveal significant differences in eye movements between the best and worst performing students. For instance, the best students performed predominantly horizontal and vertical saccades, indicating correct interpretation of partial derivatives. They also focused on smaller regions when they balanced positive and negative flux. This mixed-method research leads to new insights into student visual processing of vector field representations, highlights the advantages and limitations of eye-tracking methodologies in this context, and discusses implications for teaching and for future research. The introduction of saccadic direction analysis expands traditional methods, and shows the potential to discover new insights into student understanding and learning difficulties.

Occupational therapy relies primarily on communication between the therapist and client for effective intervention. Adequate communication may be influenced by language and cultural differences between the therapist and client. Cultural competence in relation to language and culture is thus a vital part in practice. Limited research exists on cultural competence in occupational therapy students. This study thus aimed to explore the cultural competence of final year students and their perceptions of their own cultural competence, with respect to language and culture in their practice as students. An explorative qualitative study design was utilised with a nonprobability purposeful sample of 21 final year undergraduate students at a tertiary institute in South Africa. Three focus groups were conducted, comprising between 6 and 8 students in each group. Thematic analysis using inductive reasoning was undertaken in order to analyse the students' experiences and understanding of cultural competence. Findings of the study suggest that cultural competence, in relation to language and culture, influences the occupational therapy intervention process. It was shown to both positively and negatively influence intervention through supporting or hindering rapport building, client centeredness, and effective intervention.

Exploring Responses to Art in Adolescence: A Behavioral and Eye-Tracking Study

Science.gov (United States)

Savazzi, Federica; Massaro, Davide; Di Dio, Cinzia; Gallese, Vittorio; Gilli, Gabriella; Marchetti, Antonella

2014-01-01

Adolescence is a peculiar age mainly characterized by physical and psychological changes that may affect the perception of one's own and others' body. This perceptual peculiarity may influence the way in which bottom-up and top-down processes interact and, consequently, the perception and evaluation of art. This study is aimed at investigating, by means of the eye-tracking technique, the visual explorative behavior of adolescents while looking at paintings. Sixteen color paintings, categorized as dynamic and static, were presented to twenty adolescents; half of the images represented natural environments and half human individuals; all stimuli were displayed under aesthetic and movement judgment tasks. Participants' ratings revealed that, generally, nature images are explicitly evaluated as more appealing than human images. Eye movement data, on the other hand, showed that the human body exerts a strong power in orienting and attracting visual attention and that, in adolescence, it plays a fundamental role during aesthetic experience. In particular, adolescents seem to approach human-content images by giving priority to elements calling forth movement and action, supporting the embodiment theory of aesthetic perception.

This study is to analyze the effects of medical students' social support and career barriers on career exploration behavior mediated by career decision-making self-efficacy. We applied the t-test to investigate the difference among the variables based on gender and admission types. Also, we performed path analysis to verify the effect of perceived career barriers and social support on career exploration behavior with career decision efficacy as a mediator. First, we noted statistically significant gender and admission type difference in social support, career barriers and career exploration behaviors. Second, social support and career barriers were found to influence career exploration behavior as a mediating variable for career decision-making self-efficacy. Social support and career barriers as perceived by medical students influenced their career exploration behavior, with their decision-making self-efficacy serving as a full mediator. Therefore, this study has educational implications for career program development and educational training for career decision-making self-efficacy.

A teaching resource using the GUIDE environment: simplified model of the eye for secondary school students

Gómez-Varela, A. I.; Salvado-Vara, F.; Bao-Varela, C.

2014-07-01

Nowadays, new technologies have great influence on our lives and how we access to the information. The new generations have never known a world without them and make use of these new technologies in practically all facets of their day-to-day. Education systems have also evolved rapidly and frequently make use of learning strategies based on interactive tools. In this work we have created a graphical user interface with GUIDE, a development environment of MATLAB, to show, in a simple way, how the eye works. This interactive program is addressed to the first courses of secondary education and designed to introduce them to the basic concepts of the normal refractive condition of the eye and the most common refractive errors, as myopia and hyperopia. The graphic interface makes use of the simplified model of the eye, where the optic system of the visual organ is represented by a converging lens (cornea and crystalline) and a screen (retina). Emmetropic, myopic and hyperopic eye operation is shown graphically to the students, as well as how these focusing errors can be solved with a diverging and converging lens, respectively. This teaching tool was used this academic course in the Colegio Hogar de Santa Margarita (A Coruña) for a better understanding of the students in this matter and to catch their attention to the world of Optics and its importance.

Museum education and ‘the desiring eye'

DEFF Research Database (Denmark)

Illeris, Helene

2008-01-01

Abstract/Introduction: During the last 10-20 years significant changes have occurred in educational settings in art museums. Partly as a consequence of constructivist approaches to learning, the position of the ‘good learner' has turned into the position of a subject willing to participate...... in educational projects where students' ways of seeing, students' voices, and students' direct interventions have become central. The ‘desiring eye' focused on sensuous, subjective, and highly individualized forms of viewing has thereby become a central requisite in new educational settings in art galleries...... (Illeris, 2006). In this paper I will use an example from a recent educational project to explore some of the consequences that the involvement of the viewer in participatory activities might have for the act of seeing itself. I will discuss questions such as: How do new forms of experimental educational...

2018-03-01

Up until now, empirical studies in the Student Approaches to Learning field have mainly been focused on the use of self-report instruments, such as interviews and questionnaires, to uncover differences in students' general preferences towards learning strategies, but have focused less on the use of task-specific and online measures. This study aimed at extending current research on students' learning strategies by combining general and task-specific measurements of students' learning strategies using both offline and online measures. We want to clarify how students process learning contents and to what extent this is related to their self-report of learning strategies. Twenty students with different generic learning profiles (according to self-report questionnaires) read an expository text, while their eye movements were registered to answer questions on the content afterwards. Eye-tracking data were analysed with generalized linear mixed-effects models. The results indicate that students with an all-high profile, combining both deep and surface learning strategies, spend more time on rereading the text than students with an all-low profile, scoring low on both learning strategies. This study showed that we can use eye-tracking to distinguish very strategic students, characterized using cognitive processing and regulation strategies, from low strategic students, characterized by a lack of cognitive and regulation strategies. These students processed the expository text according to how they self-reported. © 2017 The British Psychological Society.

Full Text Available Color preferences in engineering are very important, and there exists relationship between color preference and visual comfort. In this study, there are thirty university students who participated in the experiment, supplemented by pre- and posttest questionnaires, which lasted about an hour. The main purpose of this study is to explore the visual effects of different color assignment with subjective color preferences via eye tracking technology. Eye-movement data through a nonlinear analysis detect slight differences in color preferences and visual comfort, suggesting effective physiological indicators as extensive future research discussed. Results found that the average pupil size of eye-movement indicators can effectively reflect the differences of color preferences and visual comfort. This study more confirmed that the subjective feeling will make people have misjudgment.

Moon 101: Introducing Students to Lunar Science and Exploration

Science.gov (United States)

Shaner, A. J.; Shipp, S. S.; Allen, J. S.; Kring, D. A.

2011-12-01

Moon 101 is designed with the purpose of familiarizing students with lunar geology and exploration. Armed with guiding questions, students read articles covering various lunar science topics and browse images from past and current lunar missions to familiarize themselves with available lunar data sets. Moon 101 was originally created for high school students preparing to conduct open-inquiry, lunar research. Most high school students' knowledge of lunar science is limited to lunar phases and tides, and their knowledge of lunar exploration is close to non-existent. Moon 101 provides a summary of the state of knowledge of the Moon's formation and evolution, and the exploration that has helped inform the lunar science community. Though designed for high school students, Moon 101 is highly appropriate for the undergraduate classroom, especially at the introductory level where resources for teaching lunar science are scarce. Moon 101 is comprised of two sections covering lunar science (formation and geologic evolution of the Moon) and one section covering lunar exploration. Students read information on the formation and geologic evolution of the Moon from sources such as the Planetary Science Research Discoveries (PSRD) website and the USGS professional paper A Geologic History of the Moon by Wilhelms. While these resources are not peer-reviewed journals, the information is presented at a level more advanced than articles from newspapers and popular science magazines. This ensures that the language is accessible to students who do not have a strong lunar/planetary science background, or a strong science background in general. Formation readings include information on older and current formation hypotheses, including the Giant Impact Hypothesis, the Magma Ocean hypothesis, and the age of the lunar crust. Lunar evolution articles describe ideas such as the Late Heavy Bombardment and geologic processes such as volcanism and impact cratering. After reading the articles

2016-12-01

Since 2014, the Exploration of the Moon and Asteroids by Secondary Students, or ExMASS, program provides an opportunity for students to participate in authentic scientific research. The ExMASS program is an effort managed by the Center for Lunar Science and Exploration (CLSE). Led by the Lunar and Planetary Institute and Johnson Space Center, CLSE is one of nine teams comprising NASA's Solar System Exploration Research Virtual Institute (SSERVI). Over the course of one academic year, 10 teams of U.S. high school students conduct their own scientific investigations of Earth's Moon, or asteroids, with guidance from a scientist advisor. The program includes two elements: 1) two guided-inquiry introductory research activities that builds student knowledge of current lunar/asteroid science and lunar/asteroid data, and 2) an open-inquiry research project in which the students apply their knowledge to a self-defined project. Because the research is student-driven, it is not necessarily original research; original research is therefore not required. However, one team's research has been published in a professional journal. At the end of the school year, teams submit an abstract and research poster which are scored by a panel a judges. The top four scoring teams gather virtually to give short presentations to the judges. After presentations and time for Q&A, the judges choose one team to present in person at the Exploration Science Forum (ESF). The posters of all finalist schools are displayed at the ESF. The ExMASS program is evaluated by collecting data on changes in students' lunar/asteroid content knowledge, student attitudes toward science and science careers, and student perceptions of the processes of science in which their team participated. Exit surveys for teachers, students, and advisors are also distributed at the end of each program year to gather general feedback about the program and its impact. Results of this data from the first two years of the Ex

undergraduate midwifery programmes offer opportunities for school leavers and young people (aged less than 21 years) to enter the profession. There is limited research exploring this age groups experience of their Bachelor of Midwifery programme. In order to retain these students we need to ensure that their experiences of undertaking a Bachelor of Midwifery program are positive and barriers and challenges are minimised. this study explored young midwifery students' experience of their Bachelor of Midwifery program. a descriptive exploratory qualitative approach was used to explore the experiences of eleven students aged 20 years or less on enrolment. Data was collected using face-to-face or telephone-recorded interviews. Thematic analysis was used to analysis the data set. three major themes described the young students' experiences. The first labelled 'The challenges of being young' presented a number of age related challenges including transport issues with on-call commitments as some students had not gained a driver's license. Students experienced some degree of prejudice relating to their age from their older student peers and some clinical staff during placements. 'Finding your way' was the second theme and described the strategies students used to build confidence and competence both in the university and clinical environment. The young students reported a strong commitment to the profession. They demonstrated high levels of connection with women and found the continuity of care experiences invaluable to their learning. The final theme 'Making the transition from teenager to midwife' demonstrated some unique insights into how studying to become a midwife impacted upon their personal and professional growth. the young students in this study encountered some unique issues related to their age. However as they progressed through the program they developed confidence in themselves and visualised themselves as having a long midwifery career. They were strongly

Trustworthy-looking face meets brown eyes.

Directory of Open Access Journals (Sweden)

Karel Kleisner

Full Text Available We tested whether eye color influences perception of trustworthiness. Facial photographs of 40 female and 40 male students were rated for perceived trustworthiness. Eye color had a significant effect, the brown-eyed faces being perceived as more trustworthy than the blue-eyed ones. Geometric morphometrics, however, revealed significant correlations between eye color and face shape. Thus, face shape likewise had a significant effect on perceived trustworthiness but only for male faces, the effect for female faces not being significant. To determine whether perception of trustworthiness was being influenced primarily by eye color or by face shape, we recolored the eyes on the same male facial photos and repeated the test procedure. Eye color now had no effect on perceived trustworthiness. We concluded that although the brown-eyed faces were perceived as more trustworthy than the blue-eyed ones, it was not brown eye color per se that caused the stronger perception of trustworthiness but rather the facial features associated with brown eyes.

STUDYING STUDENT BEHAVIOR AND CHEMISTRY SKILL USING BROWSER-BASED TOOLS AND EYE-TRACKING HARDWARE

Directory of Open Access Journals (Sweden)

Norbert J. Pienta

Full Text Available Browser-based tools were created to collect quantitative data about university student problem-solving skills. Three of these tools have been described: a word question tool that creates ideal gas law and stoichiometry questions using a set of complexity factors; a Lewis structure drawing tool that enables the user to draw a solution to an ion or molecule assigned to them; and a "spheres" tool that uses spheres to represent atoms and molecules to denote the particulate nature of matter. Results from these studies show that relatively simple questions can be made very complex by the addition of many complexity factors that challenge the cognitive skills. The drawing tools can be used for instruction or to collect data about student understanding; the outcomes suggest that students with more instruction in chemistry are more successful but even the performance of students after four semesters is somewhat disappointing. Eye-tracking hardware enabled the study of the student use of the visual interface of the other tools and to study molecular representation or interpret spectral data.

2017-08-01

The requirement of employability in the job market prompted universities to conduct internship training as part of their study plans. There is a need to train students on important academic and professional skills related to the workplace with an IT component. This article describes a statistical study that measures satisfaction levels among students in the faculty of Information Technology and Computer Science in Jordan. The objective of this study is to explore factors that influence student satisfaction with regards to enrolling in an internship training program. The study was conducted to gather student perceptions, opinions, preferences and satisfaction levels related to the program. Data were collected via a mixed method survey (surveys and interviews) from student-respondents. The survey collects demographic and background information from students, including their perception of faculty performance in the training poised to prepare them for the job market. Findings from this study show that students expect internship training to improve their professional and personal skills as well as to increase their workplace-related satisfaction. It is concluded that improving the internship training is crucial among the students as it is expected to enrich their experiences, knowledge and skills in the personal and professional life. It is also expected to increase their level of confidence when it comes to exploring their future job opportunities in the Jordanian market. Copyright © 2017 Elsevier Ltd. All rights reserved.

Glaucoma is a progressive eye disease and a leading cause of visual disability. Automated assessment of the visual field determines the different stages in the disease process: it would be desirable to link these measurements taken in the clinic with patient's actual function, or establish if patients compensate for their restricted field of view when performing everyday tasks. Hence, this study investigated eye movements in glaucomatous patients when viewing driving scenes in a hazard perception test (HPT). The HPT is a component of the UK driving licence test consisting of a series of short film clips of various traffic scenes viewed from the driver's perspective each containing hazardous situations that require the camera car to change direction or slow down. Data from nine glaucomatous patients with binocular visual field defects and ten age-matched control subjects were considered (all experienced drivers). Each subject viewed 26 different films with eye movements simultaneously monitored by an eye tracker. Computer software was purpose written to pre-process the data, co-register it to the film clips and to quantify eye movements and point-of-regard (using a dynamic bivariate contour ellipse analysis). On average, and across all HPT films, patients exhibited different eye movement characteristics to controls making, for example, significantly more saccades (P<0.001; 95% confidence interval for mean increase: 9.2 to 22.4%). Whilst the average region of 'point-of-regard' of the patients did not differ significantly from the controls, there were revealing cases where patients failed to see a hazard in relation to their binocular visual field defect. Characteristics of eye movement patterns in patients with bilateral glaucoma can differ significantly from age-matched controls when viewing a traffic scene. Further studies of eye movements made by glaucomatous patients could provide useful information about the definition of the visual field component required for

PixEye Virtual Reality Training has the Potential of Enhancing Proficiency of Laser Trabeculoplasty Performed by Medical Students: A Pilot Study.

Science.gov (United States)

Alwadani, Fahad; Morsi, Mohammed Saad

2012-01-01

To compare the surgical proficiency of medical students who underwent traditional training or virtual reality training for argon laser trabeculoplasty with the PixEye simulator. The cohort comprised of 47 fifth year male medical students from the College of Medicine, King Faisal University, Saudi Arabia. The cohort was divided into two groups: students (n = 24), who received virtual reality training (VR Group) and students (n = 23), who underwent traditional training (Control Group). After training, the students performed the trabeculoplasty procedure. All trainings were included concurrent power point presentations describing the details of the procedure. Evaluation of surgical performance was based on the following variables: missing the exact location with the laser, overtreatment, undertreatment and inadvertent laser shots to iris and cornea. The target was missed by 8% of the VR Group compared to 55% in the Control Group. Overtreatment and undertreatment was observed in 7% of the VR Group compared to 46% of the Control Group. Inadvertent laser application to the cornea or iris was performed by 4.5% of the VR Group compared to 34% of the Control Group. Virtual reality training on PixEye simulator may enhance the proficiency of medical students and limit possible surgical errors during laser trabeculoplasty. The authors have no financial interest in the material mentioned in this study.

Full Text Available Purpose This study is to analyze the effects of medical students’ social support and career barriers on career exploration behavior mediated by career decision-making self-efficacy. Methods We applied the t-test to investigate the difference among the variables based on gender and admission types. Also, we performed path analysis to verify the effect of perceived career barriers and social support on career exploration behavior with career decision efficacy as a mediator. Results First, we noted statistically significant gender and admission type difference in social support, career barriers and career exploration behaviors. Second, social support and career barriers were found to influence career exploration behavior as a mediating variable for career decision-making self-efficacy. Conclusion Social support and career barriers as perceived by medical students influenced their career exploration behavior, with their decision-making self-efficacy serving as a full mediator. Therefore, this study has educational implications for career program development and educational training for career decision-making self-efficacy.

Exploring students' patterns of reasoning

Science.gov (United States)

Matloob Haghanikar, Mojgan

As part of a collaborative study of the science preparation of elementary school teachers, we investigated the quality of students' reasoning and explored the relationship between sophistication of reasoning and the degree to which the courses were considered inquiry oriented. To probe students' reasoning, we developed open-ended written content questions with the distinguishing feature of applying recently learned concepts in a new context. We devised a protocol for developing written content questions that provided a common structure for probing and classifying students' sophistication level of reasoning. In designing our protocol, we considered several distinct criteria, and classified students' responses based on their performance for each criterion. First, we classified concepts into three types: Descriptive, Hypothetical, and Theoretical and categorized the abstraction levels of the responses in terms of the types of concepts and the inter-relationship between the concepts. Second, we devised a rubric based on Bloom's revised taxonomy with seven traits (both knowledge types and cognitive processes) and a defined set of criteria to evaluate each trait. Along with analyzing students' reasoning, we visited universities and observed the courses in which the students were enrolled. We used the Reformed Teaching Observation Protocol (RTOP) to rank the courses with respect to characteristics that are valued for the inquiry courses. We conducted logistic regression for a sample of 18courses with about 900 students and reported the results for performing logistic regression to estimate the relationship between traits of reasoning and RTOP score. In addition, we analyzed conceptual structure of students' responses, based on conceptual classification schemes, and clustered students' responses into six categories. We derived regression model, to estimate the relationship between the sophistication of the categories of conceptual structure and RTOP scores. However, the

The purpose of this descriptive study was to explore Native American (NA) students' perceptions of scientists by using the Draw-A-Scientist Test and to determine if differences in these perceptions exist between grade level, gender, and level of cultural tradition. Data were collected for students in Grades 9-12 within a NA grant off-reservation boarding school. A total of 133 NA students were asked to draw a picture of a scientist at work and to provide a written explanation as to what the scientist was doing. A content analysis of the drawings indicated that the level of stereotype differed between all NA subgroups, but analysis of variance revealed that these differences were not significant between groups except for students who practised native cultural tradition at home compared to students who did not practise native cultural tradition at home (p educational and career science, technology, engineering, and mathematics paths in the future. The educational implication is that once initial perceptions are identified, researchers and teachers can provide meaningful experiences to combat the stereotypes.

Barry, Sinead; Ward, Louise; Walter, Ruby

2017-10-01

The purpose of this extensive international and national literature review was to explore how phenomenography identifies nursing students' experiences of learning within preregistration (or prelicensure) nursing education. Data were collected utilizing a comprehensive search of electronic databases. Full text, peer-reviewed, and scholarly articles published in English using the search terms phenomengraph*, nurs*, student, education, and learning were reviewed. Two discreet themes emerged exploring students' experiences of learning within preregistration nursing education: (a) Phenomenography was a beneficial method to expose variation in students' understandings of a challenging concept or topic and (b) phenomenography was beneficial to evaluate teaching methods in attempt to improve student learning of challenging and complex concepts. On the basis of these findings, future research utilizing phenomenography within nursing education has potential to uncover variation in students' understandings of mental health, with future consideration of implications to nursing curriculum design and development.

2017-12-01

Full Text Available Podcasts are a useful tool for developing speaking skills in language acquisition settings, particularly within the context of the emerging Mobile Assisted Language Learning (MALL. While much research has emphasized the effectiveness of teacher-produced podcasts, this study seeks to address the gap in knowledge on student-generated podcasts in language learning. In addition to highlighting some of the main pedagogical considerations of using podcasts in language learning, this paper explores students’ perceptions of podcasts as a learning tool. To this end, this study describes the results of two surveys which were conducted with two different student cohorts over the course of two years. The surveys explored the students’ levels of acceptance and enjoyment of activities in which they had to produce their own podcasts, as well as the perceived learning benefits. The discussion section describes a range of positive learning outcomes and highlights the pedagogical implications of using podcasts in class. The paper concludes with some practical suggestions for the effective use of student-generated podcast activities in the language classroom.

An Exploration of Eye Movements when Reading Texts with Atypical Spatial Layouts

Directory of Open Access Journals (Sweden)

F Hermens

2012-07-01

Full Text Available In two experiments we explored eye movements that people make when looking at texts with an atypical spatial layout. In the first experiment, participants repeatedly viewed the same piece of text, containing sections in different languages and printed using different fonts and reading directions, while they answered different questions about what they saw. In agreement with earlier studies showing significant differences in gaze patterns across different tasks, we found that reading was strongly influenced by the questions that participants tried to answer. In the second experiment, we examined gaze patterns for different types of poems while participants performed a single task: To rate their appreciation of the poem. Poems were either in the typical form, with short lines all aligned to the left, or they were in an atypical form (“graphical poem”, with the text dispersed across the page, in different fonts, reading directions, and size. Half of the poems were from an artist known for his graphical poems, the other half were from different authors who posted their poems on a webpage. All these poems were presented in a typical and an atypical form. Participants rated the poems from the web more highly, but took less time to inspect them. Whether the poem was in a typical or an atypical layout did not influence the ratings, even though longer inspection times were found for the atypical forms. Eye movement parameters, such as fixation duration and saccade amplitude, were relatively unaffected by the layout of the poems, although some additional larger amplitude saccades could be observed for the atypical forms.

Small, Sandra P; Colbourne, Peggy A; Murray, Cynthia L

2018-01-01

Background Little attention has been given to in-depth examination of what high-fidelity simulation is like for nursing students within the context of a pediatric emergency, such as a cardiopulmonary arrest. It is possible that such high-fidelity simulation could provoke in nursing students intense psychological reactions. Purpose The purpose of this study was to learn about baccalaureate nursing students' lived experience of high-fidelity simulation of pediatric cardiopulmonary arrest. Method Phenomenological methods were used. Twenty-four interviews were conducted with 12 students and were analyzed for themes. Results The essence of the experience is that it was eye-opening. The students found the simulation to be a surprisingly realistic nursing experience as reflected in their perceiving the manikin as a real patient, thinking that they were saving their patient's life, feeling like a real nurse, and feeling relief after mounting stress. It was a surprisingly valuable learning experience in that the students had an increased awareness of the art and science of nursing and increased understanding of the importance of teamwork and were feeling more prepared for clinical practice and wanting more simulation experiences. Conclusion Educators should capitalize on the benefits of high-fidelity simulation as a pedagogy, while endeavoring to provide psychologically safe learning.

Neurons in the monkey amygdala detect eye-contact during naturalistic social interactions

Science.gov (United States)

Mosher, Clayton P.; Zimmerman, Prisca E.; Gothard, Katalin M.

2014-01-01

Summary Primates explore the visual world through eye-movement sequences. Saccades bring details of interest into the fovea while fixations stabilize the image [1]. During natural vision, social primates direct their gaze at the eyes of others to communicate their own emotions and intentions and to gather information about the mental states of others [2]. Direct gaze is an integral part of facial expressions that signals cooperation or conflict over resources and social status [3-6]. Despite the great importance of making and breaking eye contact in the behavioral repertoire of primates, little is known about the neural substrates that support these behaviors. Here we show that the monkey amygdala contains neurons that respond selectively to fixations at the eyes of others and to eye contact. These “eye cells” share several features with the canonical, visually responsive neurons in the monkey amygdala, however, they respond to the eyes only when they fall within the fovea of the viewer, either as a result of a deliberate saccade, or as eyes move into the fovea of the viewer during a fixation intended to explore a different feature. The presence of eyes in peripheral vision fails to activate the eye cells. These findings link the primate amygdala to eye-movements involved in the exploration and selection of details in visual scenes that contain socially and emotionally salient features. PMID:25283782

To explore the cultural competence of undergraduate nursing students at a college of nursing, Saudi Arabia. A descriptive exploratory design was used to explore the Saudi undergraduate nursing students' level of cultural competency. The convenience sample included 205 nursing students affiliated with a college of nursing at a health science university in Jeddah, Saudi Arabia. Data was collected using the Inventory for Assessing the Process of Cultural Competence-Revised (IAPCC-R) consisting of 25 items. The tool reported acceptable reliability of Cronbach alpha 0.89. The majority of students were culturally aware and dealt with people from different cultures. One-third preferred to have training on culture over a period of time. Half the students preferred studying a special course related to working with people from different cultures. Cultural desire reported the highest mean while cultural knowledge scored the lowest among the cultural competence subscales despite students being exposed to some cultural knowledge content in their training. Implementing the guidelines for culturally competent care assure covering all aspects of care with consideration of cultural heritage as a main concept. Comparative study of nurses' and students' perception is further recommended. Copyright © 2017 Elsevier Ltd. All rights reserved.

EYE TRACKING TO EXPLORE THE IMPACTS OF PHOTOREALISTIC 3D REPRESENTATIONS IN PEDSTRIAN NAVIGATION PERFORMANCE

Directory of Open Access Journals (Sweden)

W. Dong

2016-06-01

Full Text Available Despite the now-ubiquitous two-dimensional (2D maps, photorealistic three-dimensional (3D representations of cities (e.g., Google Earth have gained much attention by scientists and public users as another option. However, there is no consistent evidence on the influences of 3D photorealism on pedestrian navigation. Whether 3D photorealism can communicate cartographic information for navigation with higher effectiveness and efficiency and lower cognitive workload compared to the traditional symbolic 2D maps remains unknown. This study aims to explore whether the photorealistic 3D representation can facilitate processes of map reading and navigation in digital environments using a lab-based eye tracking approach. Here we show the differences of symbolic 2D maps versus photorealistic 3D representations depending on users’ eye-movement and navigation behaviour data. We found that the participants using the 3D representation were less effective, less efficient and were required higher cognitive workload than using the 2D map for map reading. However, participants using the 3D representation performed more efficiently in self-localization and orientation at the complex decision points. The empirical results can be helpful to improve the usability of pedestrian navigation maps in future designs.

Health promotion intervention in schools is a useful strategy to improve students' health awareness. The purpose of this study was to assess the effect of eye health promotion interventions on eye health literacy in school children in Vietnam. A piloted questionnaire was administered to 300 children from five secondary schools in Ba Ria-Vung Tau, Vietnam at baseline and re-administered after the eye health promotion interventions. McNemar chi-square and logistic regression were used for statistical analysis. A total of 300 children aged 12-15 years (mean, 13.3 ± 1.3 years; 60% female) participated in the baseline survey. The participation rate in the post-health promotion survey was 94.7%. After the health promotion interventions, number of children who had correct eye health knowledge increased by 10-20% (60-75% to 70-95%), more children reported having had an eye examination (63.3% to 84.7%; p promotion interventions significantly improve eye health knowledge, attitudes and practices of school children. Additionally, participation of parents and teachers as change agents may further improve children's health literacy. © The Author 2017. Published by Oxford University Press. All rights reserved.

Ramona Meraz Lewis

2016-11-01

Full Text Available Aim/Purpose\tThe purpose of this study was to explore the experiences of student affairs professionals who teach in a variety of college classroom settings. Background\tIncreasingly, student affairs professionals are serving in teaching roles inside the college classroom; yet, there are few empirical studies that explore that teaching role or the impacts of that teaching experience. Because there are so few studies, we know little of the impacts of these experiences on the individual, the institution, or students. Methodology\tThis qualitative study explores the experiences of student affairs professionals who also teach in a variety of campus and classroom settings. The 12 participants from 11 different institutions ranged in years of service in the profession from six to 40 years. They taught an array of undergraduate and graduate courses including first-year experience and career courses, general education courses, and courses in higher education graduate programs. Participants share insights on how their training as student affairs professionals impacts them in their roles as college teachers. Findings\tThe findings are categorized into two broad themes: the impacts of practice on teaching and the impacts of teaching on practice. Additionally, participants share how their teaching experiences enhanced their awareness of the academic culture of the academy, enriched their understanding of students, and improved collaborations across their campuses. Future Research\tOur research addresses the gap in the literature by providing a number of considerations on how formal teaching and student affairs practice have a recursive relationship. Future research might explore how teaching at the undergraduate level may differ from teaching at the graduate level. Future research, should explore in what, if any, ways the number of years teaching influences how professionals approach teaching. Future research on teaching might also explore the experiences of

Students completed a literature review on the selected career, interviewed a pharmacist practicing that career path in Lebanon, wrote a paper, and prepared and delivered a summary presentation to their classmates about the career pathway. Students peer evaluated their classmates after each presentation. More than 85% of the students scored ≥70% on the assignment based on their achievement of student learning outcomes. Responses on an anonymous questionnaire showed that more than 94.6% of students were satisfied with the extent to which the course allowed them to meet the established learning outcomes. A career exploration assignment provided pharmacy students with an opportunity to widen their knowledge and understanding of the different career pathways that are available for them.

Altered Mucin and Glycoprotein Expression in Dry Eye Disease.

Science.gov (United States)

Stephens, Denise N; McNamara, Nancy A

2015-09-01

Mucins are among the many important constituents of a healthy tear film. Mucins secreted and/or associated with conjunctival goblet cells, ocular mucosal epithelial cells, and the lacrimal gland must work together to create a stable tear film. Although many studies have explored the mechanism(s) whereby mucins maintain and protect the ocular surface, the effects of dry eye on the structure and function of ocular mucins are unclear. Here, we summarize current findings regarding ocular mucins and how they are altered in dry eye. We performed a literature review of studies exploring the expression of mucins produced and/or associated with tissues that comprise the lacrimal functional unit and how they are altered in dry eye. We also summarize new insights on the immune-mediated effects of aqueous tear deficiency on ocular surface mucins that we discovered using a mouse model of dry eye. Although consistent decreases in MUC5AC and altered expression of membrane-bound mucins have been noted in both Sjögren and non-Sjögren dry eye, many reports of altered mucins in dry eye are contradictory. Mechanistic studies, including our own, suggest that changes in the glycosylation of mucins rather than the proteins themselves may occur as the direct result of local inflammation induced by proinflammatory mediators, such as interleukin-1. Altered expression of ocular mucins in dry eye varies considerably from study to study, likely attributed to inherent difficulties in analyzing small-volume tear samples, as well as differences in tear collection methods and disease severity in dry eye cohorts. To better define the functional role of ocular mucin glycosylation in the pathogenesis of dry eye disease, we propose genomic and proteomic studies along with biological pathway analysis to reveal novel avenues for exploration.

[Career consciousness among Japanese female students: relationships between vocational motivation and career exploration].

Science.gov (United States)

Adachi, Tomoko

2008-04-01

This questionnaire study investigated career consciousness among 348 Japanese female freshman and sophomore college students. Variables included career consciousness (belief in the idea of a best-fit vocation, passivity, and giving priority to personal interests), vocational motives (self-improvement, interpersonal, status), as well as career decision-making self-efficacy (self-appraisal, gathering occupational information) and career exploration (self and environmental exploration). The results of causal analyses showed that the belief in the idea of a best-fit vocation and passivity had effects on all three vocational motives, but giving priority to personal interests had an effect only on motivation for self-improvement. Analysis of covariance (ANCOVA) models were constructed with career exploration as dependent variables, career consciousness as fixed factors, and career decision-making self-efficacy as covariates. The results of the analyses showed that students who had high career decision-making self-efficacy engaged in both self exploration and environmental exploration activities with a higher frequency. Students with a greater passive tendency toward their career engaged in both self and environmental exploration with a lower frequency. Belief in the idea of a best-fit vocation was associated only with differences in frequency of self exploration. Giving priority to personal interests did not produce differences in career exploration activities.

Unlocking Resources: Self-Guided Student Explorations of Science Museum and Aquarium Exhibits

Science.gov (United States)

Kirkby, K. C.; Phipps, M.; Hamilton, P.

2010-12-01

Remarkably few undergraduate programs take full advantage of the rich resources provided by science museums, aquariums and other informal science education institutions. This is not surprising considering the logistical hurdles of class trips, but an even more fundamental barrier is that these institutions’ exhibit text seldom explicitly convey their information at a level suitable for undergraduate curriculum. Traditionally, this left the burden of interpretation on individual instructors, who rarely have the time to undertake it. To overcome these hurdles, the University of Minnesota has partnered with the Science Museum of Minnesota and Underwater Adventures Aquarium to test the efficacy of self-guided student explorations in revealing the rich data encoded in museum and aquarium exhibits. An initial module at the Science Museum of Minnesota focused on interpreting animal designs, specifically exploring how differences in dinosaur skeletal features reflected variations in the animals’ lifestyles. Students learn to interpret diet and lifestyle not only from characteristics of the skull and teeth, but also from variations in vertebrae and rib design or the relative proportion of limb elements. A follow-up module, based on exhibits at Underwater Adventures Aquarium focuses on interpreting energy flow through ecosystems from the behavior of living organisms. Students explore the information on lifestyle and diet that is encoded in a sturgeon’s ceaseless glide or a muskellunge’s poised stillness. These modules proved to be immensely popular with students. In classes with up to 500 students, half to two-thirds of the students volunteered to complete the modules, despite the additional expense and distances of up to 13 miles between the University and partner institutions. More importantly, quantitative assessment with pre-instruction and post-instruction surveys demonstrate that these ungraded, self-guided explorations match or exceed the efficacy of

Exploring multiliteracies, student voice, and scientific practices in two elementary classrooms

Allison, Elizabeth Rowland

This study explored the voices of children in a changing world with evolving needs and new opportunities. The workplaces of rapidly moving capitalist societies value creativity, collaboration, and critical thinking skills which are of growing importance and manifesting themselves in modern K-12 science classroom cultures (Gee, 2000; New London Group, 2000). This study explored issues of multiliteracies and student voice set within the context of teaching and learning in 4th and 5th grade science classrooms. The purpose of the study was to ascertain what and how multiliteracies and scientific practices (NGSS Lead States, 2013c) are implemented, explore how multiliteracies influence students' voices, and investigate teacher and student perceptions of multiliteracies, student voice, and scientific practices. Grounded in a constructivist framework, a multiple case study was employed in two elementary classrooms. Through observations, student focus groups and interviews, and teacher interviews, a detailed narrative was created to describe a range of multiliteracies, student voice, and scientific practices that occurred with the science classroom context. Using grounded theory analysis, data were coded and analyzed to reveal emergent themes. Data analysis revealed that these two classrooms were enriched with multiliteracies that serve metaphorically as breeding grounds for student voice. In the modern classroom, defined as a space where information is instantly accessible through the Internet, multiliteracies can be developed through inquiry-based, collaborative, and technology-rich experiences. Scientific literacy, cultivated through student communication and collaboration, is arguably a multiliteracy that has not been considered in the literature, and should be, as an integral component of overall individual literacy in the 21st century. Findings revealed four themes. Three themes suggest that teachers address several modes of multiliteracies in science, but identify

Full Text Available Plagiarism has been done by students from around the globes. There has been a heated discussion of finding reasons why plagiarism occurred in academic world and Eastern students in particular. This research wants to explore how actually students perceive plagiarism in their academic writing as well as how lecturers coped with plagiarism in the students’ assignments. The research participants were taken from 2 different majors, 32 English Education students and 10 Psychology students as well as 5 lecturers from English Education Department and 3 lecturers from Psychology Faculty in one of private universities in Central Java Province, Indonesia. Questionnaires were distributed to those respondents and also interviews were conducted to several lecturers and students. The results of questionnaire and interview showed that both students and lecturers knew and understand the essence of plagiarism, however, students admitted that they still plagiarised in their assignment. Lecturers, on the other hand, revealed that they could figure out when students plagiarised others’ works. However, it was limited to crossing over assignments between students. In other words, detecting plagiarism was done manually and restricted to students’ written works only. In conclusion, despite comprehending the meaning of plagiarism, student still plagiarised since there was not any real action from lecturers to encounter it.

Neural circuits of eye movements during performance of the visual exploration task, which is similar to the responsive search score task, in schizophrenia patients and normal subjects

International Nuclear Information System (INIS)

Nemoto, Yasundo; Matsuda, Tetsuya; Matsuura, Masato

2004-01-01

Abnormal exploratory eye movements have been studied as a biological marker for schizophrenia. Using functional MRI (fMRI), we investigated brain activations of 12 healthy and 8 schizophrenic subjects during performance of a visual exploration task that is similar to the responsive search score task to clarify the neural basis of the abnormal exploratory eye movement. Performance data, such as the number of eye movements, the reaction time, and the percentage of correct answers showed no significant differences between the two groups. Only the normal subjects showed activations at the bilateral thalamus and the left anterior medial frontal cortex during the visual exploration tasks. In contrast, only the schizophrenic subjects showed activations at the right anterior cingulate gyms during the same tasks. The activation at the different locations between the two groups, the left anterior medial frontal cortex in normal subjects and the right anterior cingulate gyrus in schizophrenia subjects, was explained by the feature of the visual tasks. Hypoactivation at the bilateral thalamus supports a dysfunctional filtering theory of schizophrenia. (author)

2016-04-01

Full Text Available Purpose: Most causes of childhood visual impairment are either treatable or preventable. Eye health education plays an important role in reducing avoidable causes of visual impairment as well as to help ensure a healthy and educated community. The main objective of this study was to assess the Knowledge, Attitudes and Practices of the students and their parents on childhood eye services and barriers for accessing child eye care. Methods: The study was conducted in South Darfur State of Sudan between January and February 2015. Both quantitative and qualitative methods were used to collect data from eight secondary schools. Four schools for boys and four schools for girls were randomly selected from a list of 21 districts of South Darfur State and the Knowledge, Attitudes and Practices surveys were conducted with the students to collect quantitative data. In addition, seven focus group discussions were conducted with the children’s parents to collect qualitative data. Results: The majority (57.5% of the students reported that they knew about refractive error; however, 33.07% reported never hearing about refractive error. About 70.3% of the respondents believed that uncorrected refractive error leads to visual impairment, 21% believed refractive error did not cause visual impairment and 30.5% reported that wearing spectacles was not effective in the treatment of refractive error. With regard to the information about eye healthcare, 88.1% of the participants reported they did not have enough information about eye care. The reported need for more information about prevention, treatment and symptoms was 34.0%, 31.4% and 17.5%, respectively. With regard to barriers, 80.6% of the students reported never having had their eyes tested. The most cited barriers were cost, fear of wearing spectacles and fear of an eye examination. In addition, 72.6% of students reported that their health insurance did not cover eye care services. Most (53.6% of the parents

Full Text Available Aim. To evaluate eye drop instillation technique and to explore its determinants in glaucoma patients. Methods. One hundred and thirteen patients diagnosed with glaucoma and self-administering topical antiglaucoma eye drops for at least 1 month were evaluated. All patients instilled artificial tear solution in one eye as they would do at home. The whole process was evaluated by two study staff. A comprehensive score system associated with eye drop instillation techniques was used to quantify the instillation technique and explore its determinants such as demographic and clinical characteristics. Results. Half of the patients (48.67% finished the administration of eye drop on first attempt.1.7 eye drops were squeezed out on average. 43 patients (37.17% got contact with ocular surface or adnexa. Only 19.7% patients had eye drop instillation techniques being defined as well. 11 patients (9.7% had prior instruction regarding using eye drops, while only 4 patients knew to occlude the tear duct by pressing the dacryocyst area. Older age and worse visual acuity were found to be independent risk factors for worse instillation technique. Conclusions. Eye drop instillation technique in glaucoma patients deserves great attention from eye care practitioners during their lifelong follow-up, especially those aged older and have worse visual acuity.

Full Text Available For tertiary English as a Foreign Language (EFL students, academic writing is not an easy task. It requires knowledge of the academic writing genres with their particular linguistic features. Moreover, academic writing demands good critical thinking. This research aims to explore the students' academic writing competencies that also focus on critical thinking. The research involved thirty-six first-year tertiary EFL students from a regular class of a private university in Pontianak, West Kalimantan, Indonesia. The source for data collection was the students’ texts. Three texts were selected and the students were categorized into low, medium, and high levels of writing achievement. The text analysis utilized functional grammar rooted in systemic functional linguistics (Emilia, 2014. The analysis shows that the students, regardless of their levels of writing achievement, have little control over the schematic structure and linguistic features of an argumentative writing. The text analysis also shows that the students’ texts have some limitations as regards their critical thinking capacity. Still, a few examples of academic language were detected in the texts. The findings suggest that the lecturer should incorporate explicit teaching and cooperative learning activities to alleviate the students' difficulties and develop their academic writing and critical thinking capacity.

Scammell, Janet; Tait, Desiree; White, Sara; Tait, Michael

2017-10-01

This study uses a lifeworld perspective to explore beginning students' values about nursing. Internationally, increasing care demand, a focus on targets and evidence of dehumanized care cultures have resulted in scrutiny of practitioner values. In England, selection policy dictates that prospective nursing students demonstrate person-centred values and care work experience. However, there is limited recent evidence exploring values at programme commencement or the effect of care experience on values. Mixed method study. A total of 161 undergraduate nursing students were recruited in 2013 from one English university. Thematic content analysis and frequency distribution to reveal descriptive statistics were used. Statistical analysis indicated that most of the values identified in student responses were not significantly affected by paid care experience. Five themes were identified: How I want care to be; Making a difference; The value of learning; Perceived characteristics of a nurse; and Respecting our humanity. Students readily drew on their experience of living to identify person-centred values about nursing.

To analyze the correlation between the daily lens wear duration and dry eye syndrome. This study was an analytic cross sectional study using consecutive sampling conducted among the students in Economy and Bussiness Faculty and Faculty of Humanities in University of Sumatera Utara aged between 17 to 23 that wore contact lens continously for at least a year and 5 days a week. The symptoms were assessed using Contact Lens Dry Eye Questionnaire-8 (CLDEQ-8) and interview about their contact lens comfort; eye drops usage, contact lens washing habit, daily circumstances, places to buy contact lens and personal experince in wearing contact lens. The questionnaire was completed by 53 students. All of them were female and wore softlens wearers. The mean duration of daily wear was 8.19 ± 2.20 hours. The most common symptom experienced was dry eye and the least symptom experienced was removing lens. The most frequent symptom experienced was closing eyes and the least frequent symptom experienced was removing lenses. This study used Exact Test as analysis statistic method. The result was p > 0.05 which means there is no correlation between daily lens wear duration and dry eye syndrome. This study showed that dry eye syndrome was not correlated with daily lens wear duration, but affected by many factors such as contact lens, lens care solution, eye drops usage and environment.

The µ-opioid system promotes visual attention to faces and eyes.

Chelnokova, Olga; Laeng, Bruno; Løseth, Guro; Eikemo, Marie; Willoch, Frode; Leknes, Siri

2016-12-01

Paying attention to others' faces and eyes is a cornerstone of human social behavior. The µ-opioid receptor (MOR) system, central to social reward-processing in rodents and primates, has been proposed to mediate the capacity for affiliative reward in humans. We assessed the role of the human MOR system in visual exploration of faces and eyes of conspecifics. Thirty healthy males received a novel, bidirectional battery of psychopharmacological treatment (an MOR agonist, a non-selective opioid antagonist, or placebo, on three separate days). Eye-movements were recorded while participants viewed facial photographs. We predicted that the MOR system would promote visual exploration of faces, and hypothesized that MOR agonism would increase, whereas antagonism decrease overt attention to the information-rich eye region. The expected linear effect of MOR manipulation on visual attention to the stimuli was observed, such that MOR agonism increased while antagonism decreased visual exploration of faces and overt attention to the eyes. The observed effects suggest that the human MOR system promotes overt visual attention to socially significant cues, in line with theories linking reward value to gaze control and target selection. Enhanced attention to others' faces and eyes represents a putative behavioral mechanism through which the human MOR system promotes social interest. © The Author (2016).

Maxwellian Eye Fixation during Natural Scene Perception

Directory of Open Access Journals (Sweden)

Jean Duchesne

2012-01-01

Full Text Available When we explore a visual scene, our eyes make saccades to jump rapidly from one area to another and fixate regions of interest to extract useful information. While the role of fixation eye movements in vision has been widely studied, their random nature has been a hitherto neglected issue. Here we conducted two experiments to examine the Maxwellian nature of eye movements during fixation. In Experiment 1, eight participants were asked to perform free viewing of natural scenes displayed on a computer screen while their eye movements were recorded. For each participant, the probability density function (PDF of eye movement amplitude during fixation obeyed the law established by Maxwell for describing molecule velocity in gas. Only the mean amplitude of eye movements varied with expertise, which was lower in experts than novice participants. In Experiment 2, two participants underwent fixed time, free viewing of natural scenes and of their scrambled version while their eye movements were recorded. Again, the PDF of eye movement amplitude during fixation obeyed Maxwell’s law for each participant and for each scene condition (normal or scrambled. The results suggest that eye fixation during natural scene perception describes a random motion regardless of top-down or of bottom-up processes.

When we explore a visual scene, our eyes make saccades to jump rapidly from one area to another and fixate regions of interest to extract useful information. While the role of fixation eye movements in vision has been widely studied, their random nature has been a hitherto neglected issue. Here we conducted two experiments to examine the Maxwellian nature of eye movements during fixation. In Experiment 1, eight participants were asked to perform free viewing of natural scenes displayed on a computer screen while their eye movements were recorded. For each participant, the probability density function (PDF) of eye movement amplitude during fixation obeyed the law established by Maxwell for describing molecule velocity in gas. Only the mean amplitude of eye movements varied with expertise, which was lower in experts than novice participants. In Experiment 2, two participants underwent fixed time, free viewing of natural scenes and of their scrambled version while their eye movements were recorded. Again, the PDF of eye movement amplitude during fixation obeyed Maxwell's law for each participant and for each scene condition (normal or scrambled). The results suggest that eye fixation during natural scene perception describes a random motion regardless of top-down or of bottom-up processes. PMID:23226987

In many underdeveloped and third world countries, eye care is often neglected due to illiteracy. Particularly people in rural areas suffer with eye problems due to mal nutrition. The government is spending lot of money and efforts in screening the people at periodic intervals. One of the challenges faced by the doctors is screening the school children. The standard Snellen letter chart based diagnostic system does not work always. There are instances where the first few students who undergo this diagnostic system, memorize the letter sequence of the Snellen letter chart and convey the same to other fellow students. Hence other students simply read out the Snellen letter sequence from their memory, not by looking at the Snellen letter chart. Thus there is a need of randomizing the sequence of letters being displayed on the Snellen letter chart for every student to be diagnosed for eye testing. In the present paper we are proposing a customizable, software based, cost effective solution which involves a standard personal computer (PC) fitted with a camera, headphone and speaker system. The envisaged system can be administered even by the trained persons. The proposed system is also suitable for remote diagnosis of patients, particularly in the field of telemedicine.

Full Text Available Abstract Objective – This research project explored Native American students’ perceptions of the Edmon Low Library at Oklahoma State University (OSU. The study sought to understand how Native American students perceived the role of the academic library in their lives, and which elements of the library students depicted and described as holding meaning for them. Methods – Photo-elicitation, a form of visual research and a participatory research method, was the primary method chosen to explore students’ perceptions of the library. To qualify for this study, students self-identified as Native American and as frequent library users. They also had completed three or more semesters of study at OSU. Five students followed a photo prompt for taking at least fifteen pictures of the library, then participated in two separate interviews with the primary researcher. Participants also completed a demographic/questionnaire form, answered semi-structured questions, and ranked the photos they took. Results – This study produced several emergent findings. First, students expressed uncertainty about the library’s books. Second, functional library tools such as express printers and library signage played a valuable role for facilitating student work. Third, the method of photo-elicitation was enjoyable for students and served as library discovery. Fourth, Native American resources and exhibits in the library had varied salience for students. Conclusion – Limited research focuses on Native American students in academic libraries, particularly on how students use and experience the library. Exploring how individual students who identify as Native American perceive the university library enhanced our understanding of how libraries in Predominantly White Institutions (PWIs can best serve and support students. This study provided insight into the method of photo-elicitation interviews. This research also provided practical benefits for student

Guo, Baobao; Wu, Qiang; Sun, Jiande; Yan, Hua

2017-06-01

Eye movement is a new kind of feature for biometrical recognition, it has many advantages compared with other features such as fingerprint, face, and iris. It is not only a sort of static characteristics, but also a combination of brain activity and muscle behavior, which makes it effective to prevent spoofing attack. In addition, eye movements can be incorporated with faces, iris and other features recorded from the face region into multimode systems. In this paper, we do an exploring study on eye movement identification based on the eye movement datasets provided by Komogortsev et al. in 2011 with different classification methods. The time of saccade and fixation are extracted from the eye movement data as the eye movement features. Furthermore, the performance analysis was conducted on different classification methods such as the BP, RBF, ELMAN and SVM in order to provide a reference to the future research in this field.

Many nursing students enter undergraduate programmes with preconceived ideas about their future nursing careers, and intend to practice in particular areas such as midwifery or paediatrics. Through clinical placements, students are exposed to different clinical areas and professional socialization is facilitated. However, little is known about the influence of clinical placements on students' career intentions. This paper reports nursing findings drawn from a large qualitative study conducted in Victoria, Australia that sought to explore the influence of health professional students' clinical placements on their future career intentions. Participants were invited to be involved in either face-to-face or focus group interviews depending upon their own preference. Thematic data analysis revealed three main themes: 're-affirming career choice', 'working in a particular area' and 'work location'. Findings from the study add to our understanding of factors influencing nursing students' planning for their future careers including the impact of clinical placements.

This study aims to identify other challenges besides those already faced by students, in seven polytechnics in Malaysia as a continuation to the previous research that had identified 52 main challenges faced by students using the Rasch Model. The explorative study focuses on the challenges that are not included in the Mooney Problem Checklist (MPCL). A total of 121 polytechnic students submitted 183 written responses through the open questions provided. Two hundred fifty two students had responded from a students' perspective on the dichotomous questions regarding their view on the challenges faced. The data was analysed qualitatively using the NVivo 8.0. The findings showed that students from Politeknik Seberang Perai (PSP) gave the highest response, which was 56 (30.6%) and Politeknik Metro Kuala Lumpur (PMKL) had the lowest response of 2 (1.09%). Five dominant challenges were identified, which were the English language (32, 17.5%), learning (14, 7.7%), vehicles (13, 7.1%), information technology and communication (ICT) (13, 7.1%), and peers (11, 6.0%). This article, however, focus on three apparent challenges, namely, English language, vehicles, as well as computer and ICT, as the challenges of learning and peers had been analysed in the previous MPCL. The challenge of English language that had been raised was regarding the weakness in commanding the aspects of speech and fluency. The computer and ICT challenge covered the weakness in mastering ICT and computers, as well as computer breakdowns and low-performance computers. The challenge of vehicles emphasized the unavailability of vehicles to attend lectures and go elsewhere, lack of transportation service in the polytechnic and not having a valid driving license. These challenges are very relevant and need to be discussed in an effort to prepare polytechnics in facing the transformational process of polytechnics.

This study examined eye movements during a visual search task as well as cognitive abilities within three age groups. The aim was to explore scanning patterns across symbol grids and to better understand the impact of symbol location in AAC displays on speed and accuracy of symbol selection. For the study, 60 students were asked to locate a series of symbols on 16 cell grids. The EyeLink 1000 was used to measure eye movements, accuracy, and response time. Accuracy was high across all cells. Participants had faster response times, longer fixations, and more frequent fixations on symbols located in the middle of the grid. Group comparisons revealed significant differences for accuracy and reaction times. The Leiter-R was used to evaluate cognitive abilities. Sustained attention and cognitive flexibility scores predicted the participants' reaction time and accuracy in symbol selection. Findings suggest that symbol location within AAC devices and individuals' cognitive abilities influence the speed and accuracy of retrieving symbols.

Abstract Nursing education has increasingly turned to international learning experiences to educate students who are globally minded and aware of social injustices in local and global communities. To date, research with international learning experiences has focused on the benefits for the students participating, after they have completed the international experience. The purpose of this qualitative study was to explore how nursing students learn during the international experience. The sample consisted of eight nursing students who enrolled in an international learning experience, and data were collected in "real time" in Zambia. The students were observed during learning activities and were interviewed three times. Three major themes emerged from the thematic analysis: expectations shaped students' learning, engagement facilitated learning, and critical reflection enhanced learning. Implications are discussed, related to disrupting media representations of Africa that shape students' expectations, and educational strategies for transformative learning and global citizenship.

2016-01-01

Introduction: This study explores the expectations and experiences of newly qualified diagnostic radiographers during their transition into practice. Methods: This was a longitudinal study using interpretative phenomenological analysis methodology. Data were gathered from four students who participated in a focus group. This informed semi structured interviews with a further eight students who were interviewed prior to starting work and three times over the following twelve months. Results: Themes generated from the data included; experience, fitting in, and identity. Conclusion: This study brings to light the experiences of newly qualified diagnostic radiographers. The findings are open to theoretical generalizability and raise issues that may be used by academic staff in the preparation of students and managers who support newly qualified staff members. - Highlights: • Diagnostic radiographers are well prepared for most clinical practice. • Clinical education cannot fully prepare students for the reality of practice. • Being familiar with a hospital, and staff, reduces the stress of starting work. • Newly qualified radiographers struggle taking responsibility for students. • Professional identity is a key issue in the transition from student to practitioner.

Micro-RNAs and their roles in eye disorders.

Science.gov (United States)

Raghunath, Azhwar; Perumal, Ekambaram

2015-01-01

Micro-RNAs (miRNAs) are members of the family of noncoding RNA molecules that regulate gene expression by translational repression and mRNA degradation. Initial identification of miRNAs revealed them only as developmental regulators; later, their radiated roles in various cellular processes have been established. They regulate several pathways, including developmental timing, hematopoiesis, organogenesis, apoptosis, cell differentiation and proliferation. Their roles in eye disorders are being explored by biologists around the world. Eye physiology requires the perfect orchestration of all the regulatory networks; any defect in any of the networks leads to eye disorders. The dysregulation of miRNA expression has been reported in many eye disorders, which paves the way for new therapeutics. This review summarizes the biogenesis of miRNAs and their role in eye disorders. miRNA studies also have implications for the understanding of various complex metabolic pathways leading to disorders of the eye. The ultimate understanding leads to potential opportunities in evaluating miRNAs as molecular biomarkers, prognostic tools, diagnostic tools and therapeutic agents for eye disorders. © 2015 S.

Advances in scientific visualization and public access to data have transformed science outreach and communication, but have yet to realize their potential impacts in the realm of education. Computer-based learning is a clear bridge between visualization and education, but creating high-quality learning experiences that leverage existing visualizations requires close partnerships among scientists, technologists, and educators. The Infiniscope project is working to foster such partnerships in order to produce exploration-driven learning experiences around NASA SMD data and images, leveraging the principles of ETX (Education Through eXploration). The visualizations inspire curiosity, while the learning design promotes improved reasoning skills and increases understanding of space science concepts. Infiniscope includes both a web portal to host these digital learning experiences, as well as a teaching network of educators using and modifying these experiences. Our initial efforts to enable student discovery through active exploration of the concepts associated with Small Worlds, Kepler's Laws, and Exoplanets led us to develop our own visualizations at Arizona State University. Other projects focused on Astrobiology and Mars geology led us to incorporate an immersive Virtual Field Trip platform into the Infiniscope portal in support of virtual exploration of scientifically significant locations. Looking to apply ETX design practices with other visualizations, our team at Arizona State partnered with the Jet Propulsion Lab to integrate the web-based version of NASA Eyes on the Eclipse within Smart Sparrow's digital learning platform in a proof-of-concept focused on the 2017 Eclipse. This goes a step beyond the standard features of "Eyes" by wrapping guided exploration, focused on a specific learning goal into standards-aligned lesson built around the visualization, as well as its distribution through Infiniscope and it's digital teaching network.

Research has indicated that misconceptions hamper the process of knowledge construction. Misconceptions are defined as persistent ideas not supported by current scientific views. Few studies have explored how misconceptions develop when first year health students conceptually move between anatomy and physiology to construct coherent knowledge about the human body. This explorative study analysed lecturers' perceptions of first-year health science students' misconceptions in anatomy and physiology to gain a deeper understanding of how and why misconceptions could potentially arise, by attempting to link sources of misconceptions with four schools of thought, namely theories on concept formation, complexity, constructivism and conceptual change. This was a qualitative study where ten lecturers involved in teaching anatomy and physiology in the health science curricula at the University of Cape Town were interviewed to explore perceptions of students' misconceptions. Analytical induction was used to uncover categories within the interview data by using a coding system. A deeper analysis was done to identify emerging themes that begins to explore a theoretical understanding of why and how misconceptions arise. Nine sources of misconceptions were identified, including misconceptions related to language, perception, three dimensional thinking, causal reasoning, curricula design, learning styles and moving between macro and micro levels. The sources of misconceptions were then grouped together to assist educators with finding educational interventions to overcome potential misconceptions. This explorative study is an attempt in theory building to understand what is at the core of biomedical misconceptions. Misconceptions identified in this study hold implications for educators as not all students have the required building blocks and cognitive skills to successfully navigate their way through biomedical courses. Theoretical insight into the sources of misconceptions can

The Effect of Eye Contact Is Contingent on Visual Awareness

Directory of Open Access Journals (Sweden)

Shan Xu

2018-02-01

Full Text Available The present study explored how eye contact at different levels of visual awareness influences gaze-induced joint attention. We adopted a spatial-cueing paradigm, in which an averted gaze was used as an uninformative central cue for a joint-attention task. Prior to the onset of the averted-gaze cue, either supraliminal (Experiment 1 or subliminal (Experiment 2 eye contact was presented. The results revealed a larger subsequent gaze-cueing effect following supraliminal eye contact compared to a no-contact condition. In contrast, the gaze-cueing effect was smaller in the subliminal eye-contact condition than in the no-contact condition. These findings suggest that the facilitation effect of eye contact on coordinating social attention depends on visual awareness. Furthermore, subliminal eye contact might have an impact on subsequent social attention processes that differ from supraliminal eye contact. This study highlights the need to further investigate the role of eye contact in implicit social cognition.

2005-02-01

The authors conducted a study in 100 non-smoker healthy normal human subjects to find a relationship between eye dominance and macular function as tested by using transient stimulus and electroretinography. Eye preference procedure was carried out using two reference points and pattern electroretinograms (PERGs) were recorded using black and white checks, each check subtending 23'. Trace averager was retriggered every 300 milliseconds (ms) with data collection time of 150 ms. The difference in PERG P50 amplitudes between right and left eyes was analyzed using Student's t test. There was no significant difference in PERG P50 amplitudes between the right and left eye dominant subjects as well as no significant differences between the right and left eyes in right eye dominants and left eye dominants, but in the left-eye dominant group the left eye PERG P50 amplitudes were significantly higher in females than males. Although pattern-reversal visual evoked potentials of healthy subjects provide electrophysiological evidence of lateralization in the nervous system, sensory eye dominance seems to have no correlation with macular function.

Full Text Available This article outlines four research methods we’ve employed to enhance how students from low-income backgrounds engage in research exploring effective teaching. It firstly outlines the need to be innovative, drawing Article 12 of the United Nations Convention on the Rights of the Child, and then moves on to explain two methods that scaffold a semi-structured interview, one child-led classroom tour and finally a creative ‘draw and tell’ approach. It argues that these methods are successful because they disrupt the researcher-participant power imbalance using the following techniques: Familiarity to the student, empowering the student to be an expert, and giving the student choice.

Silence, an Eye of Knowledge

Directory of Open Access Journals (Sweden)

Mehdi Aghamohammadi

2017-04-01

Full Text Available One of the conspicuous features of the twentieth-century West was silence. This idea could be supported by examining reflections of Ludwig Wittgenstein, Fritz Mauthner, John Cage, Samuel Beckett, Ihab Hassan, Franz Kafka, Wassily Kandinsky, Jean-Paul Sartre, Virginia Woolf, Wolfgang Iser, Jacques Derrida, and Pierre Macherey. To me, silence is not a mere theory, but rather a phenomenon from which we can get practical benefits. I believe silence is an eye, eye of knowledge. We can broaden our knowledge of the world through silence. To convey the idea that silence is an eye, I have concocted the word slence, where  has replaced the letter i and stands for the eye. This means knowledge can enable us to see, thereby acquiring knowledge of, what used to be invisible, and accordingly unknowable. In other words, through silence, we can achieve a certain type of literacy. I substantiate this claim by exploring the Horus myth, Ojo de Dios, John Cage’s 4' 33", the nature of Expressionist paintings, Hinduism, thoughts of Hermes Trismegistus and Ibn al-Arabi, and practices of Mohammad, the prophet of Islam.

Connecting eye to eye

Computer Supported Collaborative Learning (CSCL) is used a frame for supporting online and blended learning in educations. The online communication and collaboration are afforded by the social collaboration. However, the social collaboration is based on the establishment of direct eye contact......

Full Text Available Aim. The current study aimed to evaluate the knowledge of eye disease and awareness of eye care among the Saudi adults and to explore existing eye-related misconceptions in the community. Methods. A cross-sectional study was conducted in Riyadh city during May and June 2016. A self-administered anonymous online questionnaire was used to explore the most common misconceptions related to eye diseases and eye care. Results. Out of 1000 individuals, only 711 (71.1% participant responses were received. The participants’ acceptable knowledge (score ≥50% was high about the eye problem in diabetes (88.6%, ocular trauma (81.2%, and other general eye diseases (91.3%, whereas low about refractive errors (63%, pediatric eye problems (51.5%, and glaucoma (14.8%. The variation in knowledge about specific ocular morbidities was significant (p<0.001. The majority of participants reported sources of information about the common eye diseases and eye care encountered from the community, internet-based resources, and social media. Conclusions. The majority of the participants had awareness about the common eye diseases, whereas low percentage of participant’s awareness about specific condition of eye diseases. Public eye health awareness should be more focused on social media and the internet to be able to cover the younger individuals of the community.

Palmgren, Per J; Lindquist, Ingrid; Sundberg, Tobias; Nilsson, Gunnar H; Laksov, Klara B

2014-07-19

The aim of this study was to explore areas of strength and weakness in the educational environment as perceived by undergraduate physiotherapy students and to investigate these areas in relation to the respondents' demographic characteristics. This study utilized a cross-sectional study design and employed the Dundee Ready Education Environment Measure, a 50-item, self-administered inventory relating to a variety of topics directly pertinent to educational environments. Convenience sampling was used, and the scores were compared across demographic variables. All undergraduate physiotherapy students in their first five terms of the programme in a major Swedish university were invited to participate in the study. A total of 222 students (80%) completed the inventory. With an overall score of 150/200 (75%), the students rated the educational environment in this institution as "more positive than negative". Two items consistently received deprived scores - authoritarian teachers and teaching with an overemphasis on factual learning. Students in term 4 differed significantly from others, and students with earlier university education experience perceived the atmosphere more negatively than their counterparts. There were no significant differences with regards to other demographic variables. This study provides valuable insight into how undergraduate physiotherapy students perceive their educational environment. In general, students perceived that their educational programme fostered a sound educational environment. However, some areas require remedial measures in order to enhance the educational experience.

Neal, Jennifer Watling; Cappella, Elise; Wagner, Caroline; Atkins, Marc S.

2010-01-01

This study examines the association between classroom characteristics and teacher-student agreement in perceptions of students’ classroom peer networks. Social network, peer nomination, and observational data were collected from a sample of second through fourth grade teachers (N=33) and students (N=669) in 33 classrooms across five high poverty urban schools. Results demonstrate that variation in teacher-student agreement on the structure of students’ peer networks can be explained, in part, by developmental factors and classroom characteristics. Developmental increases in network density partially mediated the positive relationship between grade level and teacher-student agreement. Larger class sizes and higher levels of normative aggressive behavior resulted in lower levels of teacher-student agreement. Teachers’ levels of classroom organization had mixed influences, with behavior management negatively predicting agreement, and productivity positively predicting agreement. These results underscore the importance of the classroom context in shaping teacher and student perceptions of peer networks. PMID:21666768

Jef C. Verhoeven

2015-12-01

Full Text Available Computers have taken an important place in the training of science students and in the professional life of scientists. It is often taken for granted that most students have mastered basic Information and Communication Technologies (ICT skills; however, it has been shown that not all students are equally proficient in this regard. Starting from theories of socialization and technology acceptance we report how we constructed a structural equation model (SEM to explore the variance in the basic ICT skill levels of science students. We also present the results of a test of this model with university bachelor’s science students. Basic ICT skills were measured using a new, elaborate instrument allowing students to rate their skills in detail. Our results show that science students score high on basic ICT skills and that our SEM explains a large part of the variation in the ICT skill levels of these students. The most explanatory power is coming from four variables: the perceived ease of use and the perceived usefulness of a personal computer, the anxiety for using a personal computer, and students’ belief that ICT is necessary for scientific research.

Optical models of the human eye.

Science.gov (United States)

Atchison, David A; Thibos, Larry N

2016-03-01

Optical models of the human eye have been used in visual science for purposes such as providing a framework for explaining optical phenomena in vision, for predicting how refraction and aberrations are affected by change in ocular biometry and as computational tools for exploring the limitations imposed on vision by the optical system of the eye. We address the issue of what is understood by optical model eyes, discussing the 'encyclopaedia' and 'toy train' approaches to modelling. An extensive list of purposes of models is provided. We discuss many of the theoretical types of optical models (also schematic eyes) of varying anatomical accuracy, including single, three and four refracting surface variants. We cover the models with lens structure in the form of nested shells and gradient index. Many optical eye models give accurate predictions only for small angles and small fields of view. If aberrations and image quality are important to consider, such 'paraxial' model eyes must be replaced by 'finite model' eyes incorporating features such as aspheric surfaces, tilts and decentrations, wavelength-dependent media and curved retinas. Many optical model eyes are population averages and must become adaptable to account for age, gender, ethnicity, refractive error and accommodation. They can also be customised for the individual when extensive ocular biometry and optical performance data are available. We consider which optical model should be used for a particular purpose, adhering to the principle that the best model is the simplest fit for the task. We provide a glimpse into the future of optical models of the human eye. This review is interwoven with historical developments, highlighting the important people who have contributed so richly to our understanding of visual optics. © 2016 The Authors.

Bellefontaine, Nerys

While literature suggests that nurses report incidents or potentially unsafe care delivery, there is little evidence on student nurses' practice in this area. To explore the factors that influence student in reporting concerns about practice. A qualitative study was carried out using a phenomenological approach, based on semi-structured interviews with six student nurses. Student nurses said they do not always report potentially unsafe practice they have witnessed. Four main themes were identified: the student-mentor relationship in clinical placement; actual or potential support provided by both the practice area and university; students' own personal confidence and professional knowledge base; and fear of failing clinical placements. The nursing profession needs to take stock of current organisational culture and practice, and address issues around reporting in practice. Recommendations are made to improve mentorship, nurse training and for further research.

Psychophysiological Responsivity to Script-Driven Imagery: An Exploratory Study of the Effects of Eye Movements on Public Speaking Flashforwards.

Science.gov (United States)

Kearns, Michelle; Engelhard, Iris M

2015-01-01

A principle characteristic of public speaking anxiety relates to intrusive mental images of potential future disasters. Previous research has found that the self-reported emotionality of such "flashforwards" can be reduced by a cognitively demanding, dual-task (e.g., making eye movements) performed whilst holding the mental image in-mind. The outcome measure in these earlier studies was participants' self-reported emotional intensity of the mental image. The current study (N = 34) explored whether an objective measure of emotionality would yield similar results in students with public speaking anxiety. A script-driven imagery procedure was used to measure psychophysiological responsivity to an audio script depicting a feared (public speaking) scenario before and after an eye movement intervention. Relative to the control condition (imagery only), those who made eye movements whilst holding a mental image of this scenario in-mind demonstrated a significant decrease in heart rate, which acted as a measure of emotionality. These findings add to a previous body of research demonstrating the beneficial qualities of dual-tasks and their potential for treatment of both past and future-oriented anxieties.

2016-12-01

The ExplorOcean H2O SOS: Help Heal the Ocean—Student Operated Solutions: Operation Climate Change, teaches middle and high school students about ocean threats related to climate change through hands-on activities and learning experiences in the field. During each session (in-class or after-school as a club), students build an understanding about how climate change impacts our oceans using resources provided by ExplorOcean (hands-on activities, presentations, multi-media). Through a student leadership model, students present lessons to each other, interweaving a deep learning of science, 21st century technology, communication skills, and leadership. After participating in learning experiences and activities related to 6 key climate change concepts: 1) Introduction to climate change, 2) Increased sea temperatures, 3) Ocean acidification, 4) Sea level rise, 5) Feedback mechanisms, and 6) Innovative solutions. H2O SOS- Operation Climate change participants select one focus issue and use it to design a multi-pronged campaign to increase awareness about this issue in their local community. The campaign includes social media, an interactive activity, and a visual component. All participating clubs that meet participation and action goals earn a field trip to ExplorOcean where they dive deeper into their selected issue through hands-on activities, real-world investigations, and interviews or presentations with experts. In addition to self-selected opportunities to showcase their focus issue, teams will participate in one of several key events identified by ExplorOcean, including ExplorOcean's annual World Oceans Day Expo.

Exploring Science Through Polar Exploration

Pfirman, S. L.; Bell, R. E.; Zadoff, L.; Kelsey, R.

2003-12-01

Exploring the Poles is a First Year Seminar course taught at Barnard College, Columbia University. First Year Seminars are required of incoming students and are designed to encourage critical analysis in a small class setting with focused discussion. The class links historical polar exploration with current research in order to: introduce non-scientists to the value of environmental science through polar literature; discuss issues related to venturing into the unknown that are of relevance to any discipline: self-reliance, leadership, preparation, decisions under uncertainty; show students the human face of science; change attitudes about science and scientists; use data to engage students in exploring/understanding the environment and help them learn to draw conclusions from data; integrate research and education. These goals are met by bringing analysis of early exploration efforts together with a modern understanding of the polar environment. To date to class has followed the efforts of Nansen in the Fram, Scott and Amundsen in their race to the pole, and Shackleton's Endurance. As students read turn-of-the-century expedition journals, expedition progress is progressively revealed on an interactive map showing the environmental context. To bring the exploration process to life, students are assigned to expedition teams for specific years and the fates of the student "expeditions" are based on their own decisions. For example, in the Arctic, they navigate coastal sea ice and become frozen into the ice north of Siberia, re-creating Nansen's polar drift. Fates of the teams varied tremendously: some safely emerged at Fram Strait in 4 years, while others nearly became hopelessly lost in the Beaufort Gyre. Students thus learn about variability in the current polar environment through first hand experience, enabling them to appreciate the experiences, decisions, and, in some cases, the luck, of polar explorers.

Eye tracking dysfunction (ETD) observed with standard pursuit stimuli represents a well-established biomarker for schizophrenia. How ETD may manifest during free visual exploration of real-life movies is unclear. Eye movements were recorded (EyeLink®1000) while 26 schizophrenia patients and 25 healthy age-matched controls freely explored nine uncut movies and nine pictures of real-life situations for 20 s each. Subsequently, participants were shown still shots of these scenes to decide whether they had explored them as movies or pictures. Participants were additionally assessed on standard eye-tracking tasks. Patients made smaller saccades (movies (p = 0.003), pictures (p = 0.002)) and had a stronger central bias (movies and pictures (p < 0.001)) than controls. In movies, patients' exploration behavior was less driven by image-defined, bottom-up stimulus saliency than controls (p < 0.05). Proportions of pursuit tracking on movies differed between groups depending on the individual movie (group*movie p = 0.011, movie p < 0.001). Eye velocity on standard pursuit stimuli was reduced in patients (p = 0.029) but did not correlate with pursuit behavior on movies. Additionally, patients obtained lower rates of correctly identified still shots as movies or pictures (p = 0.046). Our results suggest a restricted centrally focused visual exploration behavior in patients not only on pictures, but also on movies of real-life scenes. While ETD observed in the laboratory cannot be directly transferred to natural viewing conditions, these alterations support a model of impairments in motion information processing in patients resulting in a reduced ability to perceive moving objects and less saliency driven exploration behavior presumably contributing to alterations in the perception of the natural environment.

Students as Virtual Scientists: An exploration of students' and teachers' perceived realness of a remote electron microscopy investigation

Science.gov (United States)

Childers, Gina; Jones, M. Gail

2015-10-01

Remote access technologies enable students to investigate science by utilizing scientific tools and communicating in real-time with scientists and researchers with only a computer and an Internet connection. Very little is known about student perceptions of how real remote investigations are and how immersed the students are in the experience. This study, conducted with high school students and their teachers, explored the impact of students' perception of ownership and virtual presence during a remote investigation using a scanning electron microscope. Students were randomly assigned to one of two treatment groups: students able to select their own insect to use during the remote investigation, and students that did not select their own insects to view during the remote investigation. The results of this study showed that students in the experimental group who had choice and ownership of their insect reported being more present (less distracted) during the remote investigation than students in the control group, whereas students in the control group reported controlling the technology was easier than the experimental group. Students indicated the remote investigation was very real; however, the teachers of these students were less likely to describe the investigation as being real. The results of this study have practical implications for designing remote learning environments.

McLaughlin, Laura; Bond, Raymond; Hughes, Ciara; McConnell, Jonathan; McFadden, Sonyia

2017-09-01

To investigate image interpretation performance by diagnostic radiography students, diagnostic radiographers and reporting radiographers by computing eye gaze metrics using eye tracking technology. Three groups of participants were studied during their interpretation of 8 digital radiographic images including the axial and appendicular skeleton, and chest (prevalence of normal images was 12.5%). A total of 464 image interpretations were collected. Participants consisted of 21 radiography students, 19 qualified radiographers and 18 qualified reporting radiographers who were further qualified to report on the musculoskeletal (MSK) system. Eye tracking data was collected using the Tobii X60 eye tracker and subsequently eye gaze metrics were computed. Voice recordings, confidence levels and diagnoses provided a clear demonstration of the image interpretation and the cognitive processes undertaken by each participant. A questionnaire afforded the participants an opportunity to offer information on their experience in image interpretation and their opinion on the eye tracking technology. Reporting radiographers demonstrated a 15% greater accuracy rate (p≤0.001), were more confident (p≤0.001) and took a mean of 2.4s longer to clinically decide on all features compared to students. Reporting radiographers also had a 15% greater accuracy rate (p≤0.001), were more confident (p≤0.001) and took longer to clinically decide on an image diagnosis (p=0.02) than radiographers. Reporting radiographers had a greater mean fixation duration (p=0.01), mean fixation count (p=0.04) and mean visit count (p=0.04) within the areas of pathology compared to students. Eye tracking patterns, presented within heat maps, were a good reflection of group expertise and search strategies. Eye gaze metrics such as time to first fixate, fixation count, fixation duration and visit count within the areas of pathology were indicative of the radiographer's competency.

Brighetti, Gianni; Bonifacci, Paola; Borlimi, Rosita; Ottaviani, Cristina

2007-05-01

Capgras syndrome is characterised by the belief that a significant other has been replaced by an identical-looking impostor. These patients have no difficulties with visual recognition but fail to show a skin conductance response (SCR) to the objects of the delusion. A case of Capgras delusion (YY), specifically characterised by the absence of brain lesions, constituted a good opportunity to test the relationship between SCR hyporesponsiveness and eye movement patterns to familiar and unfamiliar faces. Visual scan path and SCR were recorded for YY and 8 controls during the presentation of family members' photographs matched with unfamiliar faces of the same sex, age, and physical likeness. Eye movement patterns were explored by selecting three specific areas of interest (AOI) involving the eyes, the mouth, and the face regions. In contrast with controls, YY showed a reduction in number and sum of fixation durations to the eyes (p.05) to familiar vs. nonfamiliar faces. SCR and fixation duration to family members' eyes were significantly correlated (r=.77) in both YY and controls. Eye region exploration seems to be related to the autonomic reactivity elicited by the affective valence of familiar faces.

The objective of this study was to investigate whether having dental hygiene students monitor video recordings of their dental explorer skills is an effective means of proper self-evaluation in dental hygiene education. The study participants comprised students of a dental hygiene training school who had completed a module on explorer skills using models, and a dental hygiene instructor who was in charge of lessons. Questions regarding 'posture', 'grip', 'finger rest' and 'operation' were set to evaluate explorer skills. Participants rated each item on a two-point scale: 'competent (1)' or 'not competent (0)'. The total score was calculated for each evaluation item in evaluations by students with and without video monitoring, and in evaluations by the instructor with video monitoring. Mean scores for students with and without video monitoring were compared using a t-test, while intraclass correlation coefficients were found by reliability analysis of student and instructor evaluations. A total of 37 students and one instructor were subject to analysis. The mean score for evaluations with and without video monitoring differed significantly for posture (P Dental Hygiene Published by John Wiley& Sons Ltd.

An Exploration Of Engagement, Motiviation And Student-Centered Learning In Physical Education

Directory of Open Access Journals (Sweden)

Barbara WARNER

2015-12-01

Full Text Available This author examines the discrepancy between the known benefits of physical activity and the startling statistics of obesity in children between the ages of 12 and 17. She queries if it is time to look at educators as contributing to this problem and questions if our current teaching styles and curriculum are working for students. In addition, the author explores the question if by allowing our students autonomy, will this equate to engagement and motivation to continue to participate in physical activities? Through a discussion of her personal experiences and a literature review focusing on the areas of autonomy, engagement and motivation, the author shares input into how and why some students experience physical education in a negative manner, and some things that educators can do to improve student engagement and motivation. Her argument demonstrates that an autonomous, student-centered teaching approach will positively affect student engagement, which in turn causes motivation and a desire to participate in life-long physical activity.

Training the intelligent eye: understanding illustrations in early modern astronomy texts.

Science.gov (United States)

Crowther, Kathleen M; Barker, Peter

2013-09-01

Throughout the early modern period, the most widely read astronomical textbooks were Johannes de Sacrobosco's De sphaera and the Theorica planetarum, ultimately in the new form introduced by Georg Peurbach. This essay argues that the images in these texts were intended to develop an "intelligent eye." Students were trained to transform representations of specific heavenly phenomena into moving mental images of the structure of the cosmos. Only by learning the techniques of mental visualization and manipulation could the student "see" in the mind's eye the structure and motions of the cosmos. While anyone could look up at the heavens, only those who had acquired the intelligent eye could comprehend the divinely created order of the universe. Further, the essay demonstrates that the visual program of the Sphaera and Theorica texts played a significant and hitherto unrecognized role in later scientific work. Copernicus, Galileo, and Kepler all utilized the same types of images in their own texts to explicate their ideas about the cosmos.

A Course Exploration: Guiding Instruction to Prepare Students as Change Agents in Educational Reform

Directory of Open Access Journals (Sweden)

Kathy L. Church, EdD

2010-08-01

Full Text Available This article explores the premise of teacher identity development through course experiences directed at inquiry and social awareness. The course exploration examines the use of various strategies used to help promote educators as change agents. Pre-service students enrolled in a one-year master’s program with teaching credential participated in a yearlong course designed to engage them in guided inquiry while making connections between theory and practice. Evaluation of the projects and student perceptions of their work suggest that guided inquiry into educational issues builds critical thinking skills and a sense of purpose, leadership, and service through shaping teacher identity.

Exploring hurdles to transfer : student experiences of applying knowledge across disciplines

Science.gov (United States)

Lappalainen, Jouni; Rosqvist, Juho

2015-04-01

This paper explores the ways students perceive the transfer of learned knowledge to new situations - often a surprisingly difficult prospect. The novel aspect compared to the traditional transfer studies is that the learning phase is not a part of the experiment itself. The intention was only to activate acquired knowledge relevant to the transfer target using a short primer immediately prior to the situation where the knowledge was to be applied. Eight volunteer students from either mathematics or computer science curricula were given a task of designing an adder circuit using logic gates: a new context in which to apply knowledge of binary arithmetic and Boolean algebra. The results of a phenomenographic classification of the views presented by the students in their post-experiment interviews are reported. The degree to which the students were conscious of the acquired knowledge they employed and how they applied it in a new context emerged as the differentiating factors.

Exploring the Concern about Food Allergies among Secondary School and University Students in Ontario, Canada: A Descriptive Analysis.

Science.gov (United States)

Majowicz, Shannon E; Jung, James K H; Courtney, Sarah M; Harrington, Daniel W

2017-01-01

Our objective was to explore the perceived risk of food allergies among students in Ontario, Canada. We analyzed blinding questions ("I am concerned about food allergies"; "food allergies are currently a big threat to my health") from three existing food safety surveys, given to high school and university undergraduate students ( n = 3,451) circa February 2015, using descriptive analysis, and explored how concern related to demographics and self-reported cooking ability using linear regression. Overall, high school students were neutral in their concern, although Food and Nutrition students specifically were significantly less concerned ( p = 0.002) than high school students overall. University undergraduates were moderately unconcerned about food allergies. Concern was highest in younger students, decreasing between 13 and 18 years of age and plateauing between 19 and 23 years. Among students aged 13-18 years, concern was higher among those who worked or volunteered in a daycare and who had previously taken a food preparation course. Among students aged 19-23 years, concern was higher among females and those with less advanced cooking abilities. Concern was significantly correlated with perceiving food allergies as a personal threat. This study offers a first exploration of perceived risk of food allergies among this demographic and can guide future, more rigorous assessments.

2012-08-01

To determine the prevalence and risk factors for dry eye syndrome (DES) among senior high school students in Shouguang, a county of Shandong Province, China. A cross-sectional survey was conducted in July 2010, and 1902 senior high school students were selected by multi-stage sampling to answer a questionnaire assessing the prevalence and risk factors for DES. DES was defined as the presence of a previous clinical diagnosis of DES or severe symptoms (both dryness and irritation constantly or often). Risk factors associated with DES were evaluated with a χ(2) test and logistic regression analyses. The prevalence of DES was 23.7%. In univariate analysis, myopia (P sleep quality (P = 0.007) were significantly associated with DES. In multivariate analysis, inadequate refractive correction (P sleep quality (P = 0.001, OR 1.342; 95% CI 1.054-1.709) were significant risk factors for DES. Senior high school students are a neglected population with a high prevalence of DES. Preventive measures directed against risks factors for DES among senior high school students may help reduce the prevalence and provide a positive impact on students' health.

`Hard science': a career option for socially and societally interested students? Grade 12 students' vocational interest gap explored

Science.gov (United States)

Struyf, Annemie; Boeve-de Pauw, Jelle; Van Petegem, Peter

2017-11-01

A key theme in science education research concerns the decline in young peoples' interest in science and the need for professionals in hard science. Goal Congruity Theory posits that an important aspect of the decision whether to pursue hard science for study or as a career is the perception that hard science careers do not fulfil social (working with people) and societal (serving or helping others) interests. In this qualitative study, we explore grade 12 students' perceptions about the social and societal orientation of hard science careers. Furthermore, we investigate the variation in students' social and societal interests. Six focus groups were conducted with 58 grade 12 students in Flanders. Our results indicate that a number of students hold stereotypical views about hard science careers' social orientation, while others believe cooperation with others is an important aspect of hard science careers nowadays. Furthermore, our results show that students believe hard science careers can be societally oriented in the sense that they often associate them with innovation or societal progress. Finally, our results indicate that students may differentiate direct versus indirect societal orientation. These findings contribute to literature regarding social and societal interests and students' perceptions of hard science careers.

2018-07-01

To assess tear film parameters, ocular surface characteristics, and dry eye symptomology in patients receiving topical anti-glaucoma medications. Thirty-three patients with a diagnosis of open angle glaucoma or ocular hypertension, receiving unilateral topical anti-glaucoma medication for at least 6 months, were recruited in a cross-sectional, investigator-masked, paired-eye comparison study. Tear film parameters, ocular surface characteristics, and dry eye symptomology of treated and fellow eyes were evaluated and compared. The mean ± SD age of the participants was 67 ± 12 years, and the mean ± SD treatment duration was 5.3 ± 4.4 years. Treated eyes had poorer non-invasive tear film breakup time (p = 0.03), tear film osmolarity (p = 0.04), bulbar conjunctival hyperaemia (p = 0.04), eyelid margin abnormality grade (p = 0.01), tear meniscus height (p = 0.03), and anaesthetised Schirmer value (p = 0.04) than fellow eyes. There were no significant differences in dry eye symptomology, meibomian gland assessments, and ocular surface staining between treated and fellow eyes (all p > 0.05). Adverse changes in tear film stability, tear osmolarity, conjunctival hyperaemia, and eyelid margins were observed in treated eyes. This suggests that inflammatory mechanisms may be implicated in the development of dry eye in patients receiving long term topical anti-glaucoma therapy. Copyright © 2018 Elsevier Inc.

Sexual Dimorphism in Eye Morphology in a Butterfly (Asterocampa leilia; Lepidoptera, Nymphalidae

Directory of Open Access Journals (Sweden)

Kristine S. Ziemba

2000-01-01

Full Text Available In the Empress Leilia butterfly, Asterocampa leilia, as in many insects, males have larger eyes than females. We explore the morphological causes and consequences of this dimorphism in eye size by comparing the corneal surface area, facet numbers, and patterns of variation in facet dimensions in males and females. We report that, with body size (measured by forewing length controlled, male eyes are consistently larger than female eyes, and that, although males and females do not differ significantly in the number of facets per eye, males have significantly larger facets. Also, males have disproportionately larger facets both frontally and dorsally. As a result of these sexual differences in eye structure, males are expected to have a larger and more acute visual field than females which could be advantageous in the context of this species' mate searching tactic.

Full Text Available Teachers and educational institutions are attempting to find an appropriate strategy to motivate as well as engage students in the learning process. Institutions are encouraging the use of gamification in education for the purpose of improving the intrinsic motivation as well as engagement. However, the students’ perspective of the issue is under-investigated. The purpose of this research study was to explore graduate students’ perspectives toward the use of gamification techniques in online learning. The study used exploratory research and survey as the data collection tool. Forty-seven graduate students (n = 47 enrolled in an instructional technology program studied in a learning management system that supports gamification (TalentLMS. The average total percentages were calculated for each survey section to compose the final perspective of the included students. The results showed a positive perception toward the use of gamification tools in online learning among graduate students. Students require effort-demanding, challenging, sophisticated learning systems that increase competency, enhance recall memory, concentration, attentiveness, commitment, and social interaction. Limitations of the study are identified, which highlights the need for further research on the subject matter.

To explore the possible mechanism of eye drops of Buddleja officinalis extract in treating dry eye of castrated rats by analyzing the expressions of Bax and Bcl-2 proteins. Forty-five Wistar male rats were randomly divided into sham-operated group, untreated group and eye drops of Buddleja officinalis Maxim. extract (treatment) group. The dry eye model was established with orchiectomy in the untreated group and treatment group. Rats in the treatment group were treated with eye drops of Buddleja officinalis Maxim. extract, one drop once, three times daily. Eyes of rats in the sham-operated group and untreated group were instilled with normal saline. After one-, two-, or three-month treatment, five rats in each group were scarified respectively. Then samples were taken to detect related indices. Expressions of Bax and Bcl-2 of lacrimal gland were checked by immunohistochemical method and quantity of apoptotic cells was counted. After one-, two- or three-month treatment, the quantities of expressions of Bax in acinar epithelial cells and glandular tube cells were significantly lower, and those of Bcl-2 were significantly higher in the treatment group than in the untreated group, and the quantities of apoptotic cells of the treatment group were significantly lower than those of the untreated group (PBuddleja officinalis Maxim. are flavonoids, which can significantly inhibit cell apoptosis in lacrimal gland.

Wei, Xueyan; Wang, Rongrong; Macdonald, Elizabeth

2015-08-01

Research on the negative effects of student cynicism has been limited, especially regarding its relation to student burnout. This study examined the relations among student cynicism (policy cynicism, academic cynicism, social cynicism, and institutional cynicism) and student burnout, as evidenced by emotional exhaustion, depersonalization, and reduced personal accomplishment, in a sample of 276 Chinese undergraduates. Hierarchical multiple regressions showed that four aspects of student cynicism together explained substantial variance in student burnout. Policy cynicism was the strongest contributor to emotional exhaustion. Social cynicism was the primary contributor to depersonalization, and also to reduced personal accomplishment. Student cynicism overall had the strongest relationship with reduced sense of personal achievement. The findings outline the negative functional relations between student cynicism and student burnout.

Eye injuries frequently occur in the home, at work and at play. Many result in legally blind eyes, and most are preventable. Awareness of potential hazards is essential to preventing eye injuries, particularly in children. In addition, protective devices must be used appropriately. We have developed eye protectors that have proved effective in reducing both the overall incidence and the severity of sports eye injuries.

Behaviour of medical students in seeking mental and physical health care: exploration and comparison with psychology students.

Brimstone, Renee; Thistlethwaite, Jill E; Quirk, Frances

2007-01-01

Doctors are often reluctant to seek health care through the usual channels and tend to self-diagnose and prescribe. Medical students learn attitudes and values from clinician role models and may also adopt behaviour patterns that lead them to seek help for physical and mental health problems from informal sources. This study aimed to explore the behaviour of students in seeking health care for physical and mental health problems, comparing medical with psychology students, and to understand what barriers to conventional routes of seeking health care may affect this. We administered a questionnaire asking for demographic details and responses to 2 vignettes in which a student from the respondent's discipline was experiencing firstly symptoms of a mental health problem and secondly symptoms of a physical health problem. Data were analysed with spss and univariate anovas to examine differences between respondents. A total of 172 students at the psychology and medical schools at James Cook University in Australia participated. We identified a number of barriers affecting student behaviour in seeking help, which included worries about knowing the doctor they could consult at the university health centre or having future dealings with him or her, and cost of treatment. There were differences between the 2 groups of students. There are several barriers for both psychology and medical students to accessing appropriate professional mental health care. Medical students also experience barriers to attaining appropriate physical health care when needed. Psychology and medical students were more likely to seek advice informally from friends and/or family with regard to mental health care.

Impaired eye region search accuracy in children with autistic spectrum disorders.

Directory of Open Access Journals (Sweden)

John R Pruett

Full Text Available To explore mechanisms underlying reduced fixation of eyes in autism, children with autistic spectrum disorders (ASD and typically developing children were tested in five visual search experiments: simple color feature; color-shape conjunction; face in non-face objects; mouth region; and eye region. No group differences were found for reaction time profile shapes in any of the five experiments, suggesting intact basic search mechanics in children with ASD. Contrary to early reports in the literature, but consistent with other more recent findings, we observed no superiority for conjunction search in children with ASD. Importantly, children with ASD did show reduced accuracy for eye region search (p = .005, suggesting that eyes contribute less to high-level face representations in ASD or that there is an eye region-specific disruption to attentional processes engaged by search in ASD.

Durand, Karine; Baudouin, Jean-Yves; Lewkowicz, David J; Goubet, Nathalie; Schaal, Benoist

2013-01-01

This study investigated whether an odor can affect infants' attention to visually presented objects and whether it can selectively direct visual gaze at visual targets as a function of their meaning. Four-month-old infants (n = 48) were exposed to their mother's body odors while their visual exploration was recorded with an eye-movement tracking system. Two groups of infants, who were assigned to either an odor condition or a control condition, looked at a scene composed of still pictures of faces and cars. As expected, infants looked longer at the faces than at the cars but this spontaneous preference for faces was significantly enhanced in presence of the odor. As expected also, when looking at the face, the infants looked longer at the eyes than at any other facial regions, but, again, they looked at the eyes significantly longer in the presence of the odor. Thus, 4-month-old infants are sensitive to the contextual effects of odors while looking at faces. This suggests that early social attention to faces is mediated by visual as well as non-visual cues.

2012-01-01

There is evidence in the literature that rural background significantly encourages eventual rural practice. Given the shortage of healthcare providers in rural areas, we need to explore ways of ensuring throughput and success of rural-origin students in health sciences. It is therefore important to understand who these students are, what motivates them and the factors involved in the formation of their career choices. The aim of this study is to understand the aspirations of undergraduate health science students of rural origin with regard to their future career plans. The objectives of the study include to explore and identify the key issues facing rural-origin students with regard to their future career plans. Individual interviews were conducted with 15 health science students from two South African universities. Transcriptions were analyzed with the aid of Nvivo v8 (www.qsrinternational.com). The findings suggest health science students of rural origin studying at universities in the South African context face specific challenges related to the nature of the contrast between rural and urban life, in addition to the more generic adaptations that confront all students on entering tertiary education. In order to support rural students in their studies, academic, financial, emotional and social stressors need to be addressed. Universities should strengthen existing support structures as well as aid the development of further support that may be required.Key words: career plan, health science, rural background, South Africa.

Educational Debt in the Context of Career Planning: A Qualitative Exploration of Medical Student Perceptions.

Science.gov (United States)

Phillips, Julie P; Wilbanks, Deana M; Salinas, Diana F; Doberneck, Diane M

2016-01-01

Phenomenon: Medical students in the United States face increasing educational debt because medical education costs have risen while public investment in higher education has declined. Contemporary students borrow more money and accumulate debt far surpassing that of previous generations of physicians, and both interest rates and terms of loan repayment have changed significantly in the last decade. As a result, the experiences of medical students differ from the experiences of physician educators. Little is known about how contemporary medical students view their debt in the context of career planning. Understanding contemporary U.S. medical students' lived experiences of educational debt is important, because high debt levels may affect medical students' well-being and professional development. The study's purpose was to explore contemporary students' views of their debt in the context of career planning. In 2012, 2nd-year medical students enrolled in a health policy course at one medical school were invited to write an essay about how debt influences their career choices. The authors analyzed 132 essays using immersion and crystallization and iterative, team-based coding. Code-recode strategies, member checking, and reflexivity ensured validity and rigor. Three themes emerged about the meaning of debt: debt symbolizes lack of social investment, debt reinforces a sense of entitlement, and debt is a collective experience. Four approaches to debt management emerged: anticipation, avoidance, acceptance, and disempowerment. Insights: Medical students' views of debt are more complex than previously reported. Medical educators should recognize that many students experience debt as a stressor, acknowledge students' emotions about debt, and invite discussion about the culture of entitlement in medical education and how this culture affects students' professionalism. At the same time, educators should emphasize that students have many repayment options and that regardless

``Staying in Focus'' - An Online Optics Tutorial on the Eye

Science.gov (United States)

Hoeling, Barbara M.

2011-02-01

The human eye and its vision problems are often used as an entry subject and attention grabber in the teaching of geometrical optics. While this is a real-life application students can relate to, it is difficult to visualize how the eye forms images by studying the still pictures and drawings in a textbook. How to draw a principal ray diagram or how to calculate the image distance from a given object distance and focal length might be clear to most students after studying the book, but even then they often lack an understanding of the "big picture." Where is the image of a very far away object located? How come we can see both far away and close-by objects focused (although not simultaneously)? Computer animations,2 popular with our computer-game savvy students, provide considerably more information than the still images, especially if they allow the user to manipulate parameters and to observe the outcome of a "virtual" experiment. However, as stand-alone learning tools, they often don't provide the students with the necessary physics background or instruction on how to use them.

Eye Absence Does Not Regulate Planarian Stem Cells during Eye Regeneration.

Science.gov (United States)

LoCascio, Samuel A; Lapan, Sylvain W; Reddien, Peter W

2017-02-27

Dividing cells called neoblasts contain pluripotent stem cells and drive planarian flatworm regeneration from diverse injuries. A long-standing question is whether neoblasts directly sense and respond to the identity of missing tissues during regeneration. We used the eye to investigate this question. Surprisingly, eye removal was neither sufficient nor necessary for neoblasts to increase eye progenitor production. Neoblasts normally increase eye progenitor production following decapitation, facilitating regeneration. Eye removal alone, however, did not induce this response. Eye regeneration following eye-specific resection resulted from homeostatic rates of eye progenitor production and less cell death in the regenerating eye. Conversely, large head injuries that left eyes intact increased eye progenitor production. Large injuries also non-specifically increased progenitor production for multiple uninjured tissues. We propose a model for eye regeneration in which eye tissue production by planarian stem cells is not directly regulated by the absence of the eye itself. Copyright © 2017 Elsevier Inc.

Cultural diversity among students in tertiary institutions in Australia and globally has increased rapidly in the last decade, and is continuing to do so. Focus groups were held at the University of Newcastle, NSW to: (1) examine the specific needs of international students in the Master of Pharmacy, Bachelor of Medicine and Bachelor of Nursing programs in relation to language and cultural considerations and (2) to understand the attitudes of domestic students to the cultural issues faced among their peers. The project explored these issues with the intention to inform curricula changes to accommodate the needs of culturally and linguistically diverse students. The key themes emerging from international students were: difficulties in spoken language, differences in professional roles and expectations, differences in methods of learning, inadequate social interaction outside the classroom and acceptance of differences in cultural and religious practices. The domestic student views reinforced the comments from international students both in regard to social interaction and in regard to participation in class discussions. Although local students were interested in learning from international students about their culture and religious beliefs, there were limited initiatives from both sides. There is a need for tertiary institutions that benefit economically from increasing the numbers of international students to help them to study and live in a new environment. Assistance needs to go beyond learning the English language to helping students understand its use in a professional context (health terminology and slang used by patients), the nuances of the health professional disciplines in a western society, the approach to study and problem-based learning styles and skills to assist with social interaction. The results of the present exploration have led to a series of proposed actions for the University of Newcastle. These recommendations are applicable to any "Western

Background: There has been an increasing emphasis on empowering pre-service and in-service science teachers to attend student reasoning and use formative assessments to guide student learning in recent years. Purpose: The purpose of this study was to explore pre-service science teachers' pedagogical capacity for formative assessment. Sample: This study took place in Turkey. The participants include 53 pre-service science teachers in their final year of schooling. All but two of the participants are female. Design and methods: We used a mixed-methods methodology in pursing this inquiry. Participants analyzed 28 responses to seven two-tiered questions given by four students of different ability levels. We explored their ability to identify the strengths and weaknesses in students' answers. We paid particular attention to the things that the pre-service science teachers noticed in students' explanations, the types of inferences they made about students' conceptual understanding, and the affordances of pedagogical decisions they made. Results: The results show that the majority of participants made an evaluative judgment (i.e. the answer is correct or incorrect) in their analyses of students' answers. Similarly, the majority of the participants recognized the type of mistake that the students made. However, they failed to successfully elaborate on fallacies, limitations, or strengths in student reasoning. We also asked the participants to make pedagogical decisions related to what needs to be done next in order to help the students to achieve academic objectives. Results show that 8% of the recommended instructional strategies were of no affordance, 64% of low-affordance, and 28% were of high affordance in terms of helping students achieve the academic objectives. Conclusion: If our goal is to improve pre-service science teachers' noticing skills, and the affordance of feedback that they provide, engaging them in activities that asks them to attend to students' ideas

Occupational therapy educators are challenged to provide students with practical experiences which prepare them for ever changing health-care contexts on graduation. Role-emerging placements have been widely used internationally to help meet this challenge, but research into the learning experiences of students during these innovative placements is limited. This research investigated the enablers and barriers to learning from the perspectives of students on such placements from two European universities. Two separate qualitative studies tracked 10 final year students. Interviews explored their learning experiences prior to, during and after an eight- or 10-week role-emerging placement in a range of settings. Four themes emerged, which were (1) adapting to less doing, more thinking and planning; (2) understanding the complexity of collaboration and making it work; (3) emotional extremes; and (4) realising and using the occupational therapy perspective. These placements presented a 'roller coaster' of authentic learning experiences which created the opportunity for students to use occupation in practice and develop skills for collaborative working in an interprofessional environment. Whereas students viewed their role-emerging placement experiences positively, challenges included the emotional responses of students and placement pace. Findings suggest the need for supportive student placement experiences in both established and role-emerging areas to prepare students for a range of opportunities in an uncertain future. © 2013 Occupational Therapy Australia.

Academic self-concept is one's perception of his or her ability in an academic domain and is formed by comparing oneself to other students. As college biology classrooms transition from lecturing to active learning, students interact more with each other and are likely comparing themselves more to other students in the class. Student characteristics can impact students' academic self-concept; however, this has been unexplored in the context of undergraduate biology. In this study, we explored whether student characteristics can affect academic self-concept in the context of an active learning college physiology course. Using a survey, students self-reported how smart they perceived themselves to be in the context of physiology relative to the whole class and relative to their groupmate, the student with whom they worked most closely in class. Using linear regression, we found that men and native English speakers had significantly higher academic self-concept relative to the whole class compared with women and nonnative English speakers. Using logistic regression, we found that men had significantly higher academic self-concept relative to their groupmate compared with women. Using constant comparison methods, we identified nine factors that students reported influenced how they determined whether they were more or less smart than their groupmate. Finally, we found that students were more likely to report participating more than their groupmate if they had a higher academic self-concept. These findings suggest that student characteristics can influence students' academic self-concept, which in turn may influence their participation in small-group discussion and their academic achievement in active learning classes.

The adolescent idiopathic scoliosis (AIS) pathogenesis remains unknown. Certain studies have shown that there is a correlation between manual laterality and scoliotic deviation. A full study of manual laterality needs to be paired with one for visual dominance. With the aim of physiopathological research, we have evaluated the manual and visual laterality in AIS. A retrospective study from prospective data collection is used to evaluate the distribution of eye-hand laterality (homogeneous or crossed) of 65 right thoracic AIS (mean age 14.8 ± 1.8 years; mean Cobb angle: 32.8°) and a control group of 65 sex and age-matched (mean age 14.6 ± 1.8 years). The manual laterality was defined by the modified Edinburgh Handedness Inventory. The evaluation of the visual laterality is done using three tests (kaleidoscope test, hole-in-the-card test, distance-hole-in-the-card test). The group of right thoracic AIS presents a significantly higher frequency of crossed eye-hand laterality (63 %) than the control group (63 vs. 29.2 %; p laterality is "right hand dominant-left eye dominant" (82.9 %). There is no relationship with the Cobb angle. Those with right thoracic AIS show a higher occurrence of crossed eye-hand laterality. This could point physiopathological research of AIS towards functional abnormality of the optic chiasma through underuse of cross visual pathways, and in particular accessory optic pathways. It would be useful to explore this by carrying out research on AISs through neuroimaging and neurofunctional exploration.

The aim of this study was to determine the prevalence and severity of dry eye syndrome in a group of Mexican residents of different surgical specialties. A cross-sectional descriptive study where the residents were studied using the Ocular Surface Disease Index, together with diagnostic tests for dry eye syndrome, such as tear breakup time, Oxford Schema, Schirmer's test I, and meibomian gland dysfunction testing. Statistical analyses were performed by Pearson's chi-squared test for categorical variables and student's t-test for quantitative variables. Any P value eyes); 90 (73 %) were male and 33 (27 %) were female. The mean age was 27.8 ± 2.1 years. A higher number of residents with dry eye syndrome was found in the cardiothoracic surgery (75 %) and otorhinolaryngology (71 %) specialties; 70 % of them reported ocular symptoms, with teardrop quality involvement in >50 % of them. We found a prevalence of 56 % for mild-to-moderate/severe stages of the condition. Their presence in the operating room predisposes surgical residents to dry eye syndrome because of environmental conditions.

Dry eye is a chronic inflammatory ocular surface disease with high prevalence. The current therapies for dry eye remain to be unspecific and notcomprehensive. This study aims to explore safety and efficacy of a novel treatment - subconjunctival injection of bevacizumab - in dry eye patients. Sixty-four eyes of 32 dry eye patients received subconjunctival injection of 100 μL 25 mg/mL bevacizumab. Dry eye symptoms, signs (corrected visual acuity, intraocular pressure, conjunctival vascularity, corneal staining, tear break-up time, Marx line score, and blood pressure), and conjunctival impression cytology were evaluated 3 days before and 1 week, 1 month, and 3 months after injection. Significant improvements were observed in dry eye symptoms, tear break-up time, and conjunctival vascularization area at all the visits after injection compared to the baseline (Pdry eye disease.

To increase medical students' ability to detect contextual and emotional cues and to respond empathetically to patients. a training course in communication skills and patient-centered care with different teaching activities (didactic, reflective and interactive: workshops and encounters with simulated patients) was delivered to third-year medical students just before their clerkships. The program was evaluated by an external observer (OE) and simulated patients (SP) in 2 or 3 videotaped encounters. Students improved significantly from baseline to 3rd interview in all communicative skills and domains explored both in OE (32.4%) and SP (38.3%) measurement. At the end of the course students detected significantly more clues and made more empathetic expressions. The course seems to improve the ability of students to explore the illness experience, showing more empathy in a more genuine way. This was carried out in consultations lasting 10min. The program is effective and feasible to be applied as a regular formative activity. Further research is needed to assess whether this training program is applicable to students in more advanced educational levels and if it has any additional outcomes. Copyright © 2017 Elsevier B.V.

To explore eye laterality (higher refractive error in one eye) and its association with refractive state, spherical/astigmatic anisometropia, age and sex in refractive surgery candidates. Medical records of 12 493 consecutive refractive surgery candidates were filtered. Refractive error (subjective and cycloplegic) was measured in each subject and correlated with eye laterality. Only subjects with corrected distance visual acuity (CDVA) of >20/22 in each eye were enrolled to exclude amblyopia. Associations between eye laterality and refractive state were analysed by means of t-test, chi-squared test, Spearman's correlation and multivariate logistic regression analysis, respectively. There was no statistically significant difference in spherical equivalent between right (-3.47 ± 2.76 D) and left eyes (-3.47 ± 2.76 D, p = 0.510; Pearson's r = 0.948, p laterality for anisometropia >2.5 D in myopic (-5.64 ± 2.5 D versus -4.92 ± 2.6 D; p = 0.001) and in hyperopic (4.44 ± 1.69 D versus 3.04 ± 1.79 D; p = 0.025) subjects, (II) a tendency for left eye cylindrical laterality in myopic subjects, and (III) myopic male subjects had a higher prevalence of left eye laterality. (IV) Age did not show any significant impact on laterality. Over the full refractive spectrum, this study confirmed previously described strong interocular refractive correlation but revealed a statistically significant higher rate of right eye laterality for anisometropia >2.5 D. In general, our results support the use of data from one eye only in studies of ocular refraction. © 2013 The Authors. Acta Ophthalmologica © 2013 Acta Ophthalmologica Scandinavica Foundation.

Full Text Available Research from evolutionary psychology suggests that the mere presence of eye images can promote prosocial behavior. However, the “eye images effect” is a source of considerable debate, and findings across studies have yielded somewhat inconsistent support. We suggest that one critical factor may be whether the eyes really need to be watching to effectively enhance prosocial behavior. In three experiments, we investigated the impact of eye images on prosocial behavior, assessed in a laboratory setting. Participants were randomly assigned to view an image of watching eyes (eyes with direct gaze, an image of nonwatching eyes (i.e., eyes closed for Study 1 and averted eyes for Studies 2 and 3, or an image of flowers (control condition. Upon exposure to the stimuli, participants decided whether or not to help another participant by completing a dull cognitive task. Three independent studies produced somewhat mixed results. However, combined analysis of all three studies, with a total of 612 participants, showed that the watching component of the eyes is important for decision-making in this context. Images of watching eyes led to significantly greater inclination to offer help as compared to images of nonwatching eyes (i.e., eyes closed and averted eyes or images of flowers. These findings suggest that eyes gazing at an individual, rather than any proxy to social presence (e.g., just the eyes, serve as a reminder of reputation. Taken together, we conclude that it is “eyes that pay attention” that can lift the veil of anonymity and potentially facilitate prosocial behavior.

Student nurses' experiences of community-based practice placement learning: a qualitative exploration.

United Kingdom (UK) health policy has adopted an increasing community and primary care focus over recent years (Department of Health, 1997; Department of Health, 1999. Making a Difference: Strengthening the Nursing, Midwifery and Health Visitor Contribution to Health and Health Care. Department of Health, London; Department of Health, 2004. The NHS Knowledge and Skills Framework (NHS KSF). Department of Health, London). Nursing practice, education and workforce planning are called upon to adapt accordingly (Department of Health, 2004. The NHS Knowledge and Skills Framework (NHS KSF). Department of Health, London; Kenyon, V., Smith, E., Hefty, L., Bell, M., Martaus, T., 1990. Clinical competencies for community health nursing. Public Health Nursing 7(1), 33-39; United Kingdom Central Council for Nursing, Midwifery and Health Visiting, 1986. Project 2000: A New Preparation for Practice. UKCC, London). Such changes have major implications for pre-registration nursing education, including its practice placement element. From an educational perspective, the need for increased community nursing capacity must be balanced with adequate support for student nurses' learning needs during community-based placements. This qualitative study explored six second year student nurses' experiences of 12 week community-based practice placements and the extent to which these placements were seen to meet their perceived learning needs. The data came from contemporaneous reflective diaries, completed by participants to reflect their 'lived experience' during their practice placements (Landeen, J., Byrne, Brown, B., 1995.

following the view that people with autism are not interested in processing social signals such as gaze but could do so efficiently if properly motivated. For each pathology we emphasize that eye contact could be used, for example, to enhance sensitivity to bodily states, thus improving emotional decision making (in autism); to lead to more positive appraisal of the self and others (in depression); to improve memory performances (in Alzheimer disease) and, more generally, to motivate the recipient to engage in the therapeutic process. (3) Finally we propose two concrete ways to employ eye contact effects as a therapeutic tool. The first is to develop cognitive-behavioral tools to learn and/or motivate the recipient to create frequent and prolonged eye contact periods. The second is to raise awareness among caregivers of the beneficial effects of eye contact and to teach them the way to use eye contact to reach its optimum effects. Future investigations are however needed to explore the ways in which eye contact effects can be efficiently integrated in therapeutic strategies, as well as to identify the clinical populations that can benefit from such therapeutic interventions.

2013-01-01

In recent years, medical students have recognized and advocated for opportunities to explore various specialties earlier in their medical education. A brief literature review, however, reveals little consensus on the best approach to introduce students to different fields during their preclinical years. We present one of the first reports of a student-led effort to design and implement a preclinical specialty-specific elective. At Mayo Medical School, for two consecutive years the student president of the Pediatric Interest Group has created a peer-designed weeklong group elective ("selective") experience consisting of workshops, faculty and resident panel discussions, and clinical shadowing experiences based on a student needs assessment. Each year, more than 25% of the first- and second-year medical student body participated. The majority of students who completed the selective agreed that this experience heightened their interests and expanded their knowledge about pediatrics. The pediatric group selective has provided students with important resources for their medical education and future careers. Students found the group selective beneficial to their learning experience and recommend continuing to offer it in the future.

Radiolysis characterization of chloramphenicol in powder and in eye ointment

Hong, L.; Altorfer, H.R.

2005-01-01

The effects of γ-radiation sterilization on chloramphenicol, in both pure powder state and petrolatum eye ointment, were investigated with high performance liquid chromatography. The content of chloramphenicol decreases by 1.0% in powder state and by 1.2% in eye ointment at the reference radiation dose of 25 kGy. The profile of chloramphenicol radiolysis products in powder state differs from that in eye ointment. It was found that microenvironment of chloramphenicol molecule is a key factor governing the radiolysis of chloramphenicol in powder state. Solvent residues in chloramphenicol powder could change the radiolysis behavior of chloramphenicol. The solvents, having good solubility for chloramphenicol, promote radiolytic hydrolysis of chloramphenicol, but the converses do not. Inert gas purging or diffusion by exposing in absorbent is efficient method to prevent chloramphenicol powder from radiolysis. The influence of the presence of oxygen was explored. Oxygen plays a role of scavenger and diminishes radiolysis of chloramphenicol. It was found that Nactyl-L-cysteine can protection chloramphenicol in eye ointment from radiolysis. Hydrophobic radiolysis products of chloramphenicol were observed in eye ointment part. Using scavengers and lower irradiation can be strategies to resist radiolysis of chloramphenicol in petrolatum eye ointment. (author)

Pond, Jarrad W. T.; Chini, Jacquelyn J.

2017-06-01

In this study, we explore the strategic self-regulatory and motivational characteristics of students in studio-mode physics courses at three universities with varying student populations and varying levels of success in their studio-mode courses. We survey students using questions compiled from several existing questionnaires designed to measure students' study strategies, attitudes toward and motivations for learning physics, organization of scientific knowledge, experiences outside the classroom, and demographics. Using a person-centered approach, we utilize cluster analysis methods to group students into learning profiles based on their individual responses to better understand the strategies and motives of algebra-based studio physics students. Previous studies have identified five distinct learning profiles across several student populations using similar methods. We present results from first-semester and second-semester studio-mode introductory physics courses across three universities. We identify these five distinct learning profiles found in previous studies to be present within our population of introductory physics students. In addition, we investigate interactions between these learning profiles and student demographics. We find significant interactions between a student's learning profile and their experience with high school physics, major, gender, grade expectation, and institution. Ultimately, we aim to use this method of analysis to take the characteristics of students into account in the investigation of successful strategies for using studio methods of physics instruction within and across institutions.

Eye Contricks

Directory of Open Access Journals (Sweden)

N Wade

2011-04-01

Full Text Available Icons are eye-cons: they provide a distillation of a complex object or idea into a simple pictorial shape. They create the impression of representing that which cannot be presented. Even at the level of the photograph, the links between icon and object are tenuous. The dimension of distance or depth is missing from the icon, and this alone introduces all manner of potential ambiguities. The history of art can be considered as an exploration of the missing link between icon and object. Eye-cons are more honest—they are tricks of vision so that what is seen does not necessarily correspond to what is presented. They are visual allusions rather than visual illusions, although they can display illusory effects. At its broadest, icon can be equated with image. The concept of image has thrived on its vagueness, and so attempts have been made to refine it. An icon corresponds to an optical image: it shares some of the projective characteristics of the object represented. Written words are also icons but they do not resemble the objects they represent—they are stylised or conventional rather than spatialised and projective. Words and images were set in delightful opposition by René Magritte (1898-1967 in a series of pipe paintings, and he also played on the theme of the arbitrariness of the verbal labels assigned to objects. What is surprising is that Magritte did not apply his painterly skills to transforming the word shapes he used. A similar reluctance to transform the typefaces pervades visual poetry. My interests are in the visual rather than the poetic dimension, and I will present a range of my own eye contricks which play with letter and word shapes in a variety of ways.

Full Text Available AIM: To explore the correlation between eye cyclotorsion degrees and patient's age, gender, diopter and other factors in corneal refractive surgery. METHODS: A total of 762 wavefront-guided LASIK patients with 1524 eyes were retrospectively analyzed from January 2010 to December 2013 in our hospital. Iris recognition was accomplished successfully and eye cyclotorsion degrees were recorded intraoperatively for all the patients. The correlations between eye cyclotorsion degrees and patient's age, gender, different eye, diopter and the dominant eye or not were statistically analyzed. In which correlation analysis was used to analyze the relationship between eye cyclotorsion degrees and age and diopter, while the correlations with gender, different eye and the dominant eye or not were analyzed using t-test.RESULTS: The eye cyclotorsion degrees of patients were 0 to 9.7 degrees with an average of 3.08±2.22 degrees. Amongst the average cyclotorsion of 444 men with 888 eyes were 3.05±2.26 degrees, 318 women with 636 eyes were 3.12±2.15 degrees and there were no significant differences(t=1.905, P=0.168. The average age of all the patients was 22.6±5.4y. No significant correlation was found between cyclotorsion degrees and age(r=-0.012, P=0.748. The mean spherical equivalent was -4.76±1.77 degrees, and there was no significant correlation between the eye cyclotorsion degrees and spherical equivalent(r=0.017, P=0.633. The mean cylinder was -0.60±0.64 degrees of no significant correlation with eye cyclotorsion degrees(r=-0.004, P=0.910. The cyclotorsion of dominant eyes of all the patients was 3.0±2.17 degrees, and the non-dominant eyes were 3.11±2.12 degrees. No significant differences were found(t=-0.521,P=0.603. CONCLUSION: The eye cyclotorsion degrees occurred in LASIK surgery had no correlation with age, gender, different eye, diopter and the dominant eye or not.

In metazoans, there is a remarkable diversity of photosensitive structures; their shapes, physiology, optical properties, and development are different. To approach the evolution of photosensitive structures and visual function, cephalopods are particularly interesting organisms due to their most highly centralized nervous system and their camerular eyes which constitute a convergence with those of vertebrates. The eye morphogenesis in numerous metazoans is controlled mainly by a conserved Retinal Determination Gene Network (RDGN) including pax, six, eya , and dac playing also key developmental roles in non-retinal structures and tissues of vertebrates and Drosophila . Here we have identified and explored the role of Sof-dac, Sof-six1/2, Sof-eya in eye morphogenesis, and nervous structures controlling the visual function in Sepia officinalis . We compare that with the already shown expressions in eye development of Sof-otx and Sof-pax genes. Rhodopsin is the pigment responsible for light sensitivity in metazoan, which correlate to correlate visual function and eye development. We studied Sof-rhodopsin expression during retina differentiation. By in situ hybridization, we show that (1) all of the RDGN genes, including Sof-pax6 , are expressed in the eye area during the early developmental stages but they are not expressed in the retina, unlike Sof-otx , which could have a role in retina differentiation; (2) Sof-rhodopsin is expressed in the retina just before vision gets functional, from stage 23 to hatching. Our results evidence a role of Sof-six1/2, Sof-eya , and Sof-dac in eye development. However, the gene network involved in the retinal photoreceptor differentiation remains to be determined. Moreover, for the first time, Sof-rhodopsin expression is shown in the embryonic retina of cuttlefish suggesting the evolutionary conservation of the role of rhodopsin in visual phototransduction within metazoans. These findings are correlated with the physiological and

Eye-catching odors: olfaction elicits sustained gazing to faces and eyes in 4-month-old infants.

Directory of Open Access Journals (Sweden)

Karine Durand

Full Text Available This study investigated whether an odor can affect infants' attention to visually presented objects and whether it can selectively direct visual gaze at visual targets as a function of their meaning. Four-month-old infants (n = 48 were exposed to their mother's body odors while their visual exploration was recorded with an eye-movement tracking system. Two groups of infants, who were assigned to either an odor condition or a control condition, looked at a scene composed of still pictures of faces and cars. As expected, infants looked longer at the faces than at the cars but this spontaneous preference for faces was significantly enhanced in presence of the odor. As expected also, when looking at the face, the infants looked longer at the eyes than at any other facial regions, but, again, they looked at the eyes significantly longer in the presence of the odor. Thus, 4-month-old infants are sensitive to the contextual effects of odors while looking at faces. This suggests that early social attention to faces is mediated by visual as well as non-visual cues.

2015-03-01

Full Text Available In the context of higher education, over 100 universities have signed international declarations and have committed to embed sustainability within their operations, outreach, education and research. However, despite the declaration of good intentions and policy developments at the national, regional and international level, little has been achieved in terms of embedding education for sustainable development holistically in the curriculum. To date, a number of research studies have focused on the perceptions and views of university students in relation to sustainable development knowledge, skills and competencies; however, few studies have focused on student teachers’ perceptions of education for sustainable development. The aim of this study was to explore the perceptions and views of a group of thirty-two student teachers in relation to education for sustainable development competencies. The research instrument used was a questionnaire. This study provides evidence on the education for sustainable development (ESD competencies that student teachers would prioritize in a school project related to ESD: acquisition of knowledge and practical skills related to nature and natural sciences, to the detriment of other types of learning, such as the promotion of ethical values, positive attitudes towards sustainability and the management of emotions among their future primary school students. Existing ESD theoretical frameworks need to become more alive and integrated within the existing teacher education curriculum to promote the awareness and development of ESD competencies amongst student teachers.

Making connections: Exploring student agency in a science classroom in India

Science.gov (United States)

Sharma, Ajay

India has been a free country for more than half a century now. In this time, the state has succeeded to a large extent in providing universal access to at least elementary education to all the citizens. However, the quality of education provided in state-run schools remains far removed from the ideals endorsed in policy documents. The vast majority of Indian poor, especially in rural areas, depend upon state-run schools for access to education. However, the low quality of education provided in these schools militates against their hopes and efforts for securing a better future through education. Undergirded by concerns over the raw deal students of government run schools get in rural India, this study is an ethnographic exploration of science learning in a rural middle school classroom in India. The study was conducted in the government middle school at the village Rajkheda, in the Hoshangabad district of the state of Madhya Pradesh, India. The study focused on the nature and scope of student participation in a middle school science classroom of rural school in India. Taking a socio-cultural perspective, it explored student participation in science classroom as engagement in a socioculturally mediated dialogue with the natural and the social world. Thus, two parallel yet intersecting themes run through the narrative this study presents. On one hand, it focuses on students' efforts to both learn and survive science as taught in that school. While on the other, it details the nature of their engagement with and knowledge of their immediate material world. The study shows that through active engagement with their local material and social world, students of the 8th grade had acquired an extensive, useful and situated funds of experiential knowledge that enabled them to enact their agency in the material world around them. This knowledge revealed itself differently in different contexts. Their knowledge representations about school science and the material world were

A centralized eye donation registry for research could help to bridge the gap between patients interested in donating their eyes to science and scientists who conduct research on human eye tissue. Previous research has demonstrated patient and family support for such a registry. In this study, we assessed the views that eye care professionals have toward an eye donation registry for research. Surveys were distributed to all 46 clinical faculty members of the Duke University Eye Center. In addition to collecting demographic information, the surveys assessed clinicians' experience with discussing eye donation with patients, described the proposed eye donation registry for research and asked how the registry would affect the clinicians' practice. A total of 21 eye care professionals returned the survey. Thirty-three percent reported discussing eye donation with patients, and 43% reported that a patient has asked about donating their eyes for research on their disease. Eighty-six percent of eye care professionals reported that a centralized registry would improve the way they work with patients who express a desire to donate their eyes for research. The majority of eye care professionals at our academic institution indicated that an eye donation registry for research would improve how they work with patients who are interested in donating their eyes for research on their disease. Future research should examine how best to communicate this registry to ophthalmic patients.

Full Text Available A career developed through the optimization of one’s potentials will irrevocably play a role in the development of self-identity as well as the psychological well-being of the individual. When children are introduced and allowed to explore as many career options as possible during their developmental stage, they are more likely to have a fruitful career development in the future. The preceding study showed that the career interests and knowledge of lower-grade primary students fit the Holland Career Categories: realistic, investigative, artistic, social, enterprising, and conventional (RIASEC. It was also found that the students’ career interest and knowledge levels varied, with most in the low level. This second-year study aims to expand the results of the previous study by developing the use of Quartet cards as the media of career exploration for lower-grade primary students. By using the research and development method, this study develops Quartet Career Cards into three difficulty levels: low, medium, and high. The Quartet cards media have undergone feasibility tests conducted by experts in theory and media, as well as a series of field testing consisting of preliminary, main, and operational stages among a total of 266 primary students of grades 1, 2, and 3. A revision was made on several components including the images, information, colors, font sizes, illustration styles, and card sizes. The findings show that Quartet Career Cards meet the feasibility standards for the media of career exploration

1997-01-01

Increased autonomy of robots would yield significant advantages in the exploration of space. The shortfalls of computer vision can, however, pose significant limitations on a robot's potential. At the same time, simple insects which are largely hard-wired have effective visual systems. The understanding of insect vision systems thus may lead to improved approaches to visual tasks. A good starting point for the study of a vision system is its eye. In this paper, a model of the sensory portion of the fly's eye is presented. The effectiveness of the model is briefly addressed by a comparison of its performance to experimental data.

Expert and Novice Approaches to Using Graphs: Evidence from Eye-Track Experiments

Science.gov (United States)

Wirth, K. R.; Lindgren, J. M.

2015-12-01

Professionals and students in geology use an array of graphs to study the earth, but relatively little detail is known about how users interact with these graphs. Comprehension of graphical information in the earth sciences is further complicated by the common use of non-traditional formats (e.g., inverted axes, logarithmic scales, normalized plots, ternary diagrams). Many educators consider graph-reading skills an important outcome of general education science curricula, so it is critical that we understand both the development of graph-reading skills and the instructional practices that are most efficacious. Eye-tracking instruments provide quantitative information about eye movements and offer important insights into the development of expertise in graph use. We measured the graph reading skills and eye movements of novices (students with a variety of majors and educational attainment) and experts (faculty and staff from a variety of disciplines) while observing traditional and non-traditional graph formats. Individuals in the expert group consistently demonstrated significantly greater accuracy in responding to questions (e.g., retrieval, interpretation, prediction) about graphs. Among novices, only the number of college math and science courses correlated with response accuracy. Interestingly, novices and experts exhibited similar eye-tracks when they first encountered a new graph; they typically scanned through the title, x and y-axes, and data regions in the first 5-15 seconds. However, experts are readily distinguished from novices by a greater number of eye movements (20-35%) between the data and other graph elements (e.g., title, x-axis, y-axis) both during and after the initial orientation phase. We attribute the greater eye movements between the different graph elements an outcome of the generally better-developed self-regulation skills (goal-setting, monitoring, self-evaluation) that likely characterize individuals in our expert group.

Radiology image perception and observer performance: How does expertise and clinical information alter interpretation? Stroke detection explored through eye-tracking

Science.gov (United States)

Cooper, Lindsey; Gale, Alastair; Darker, Iain; Toms, Andoni; Saada, Janak

2009-02-01

Historically, radiology research has been dominated by chest and breast screening. Few studies have examined complex interpretative tasks such as the reading of multidimensional brain CT or MRI scans. Additionally, no studies at the time of writing have explored the interpretation of stroke images; from novices through to experienced practitioners using eye movement analysis. Finally, there appears a lack of evidence on the clinical effects of radiology reports and their influence on image appraisal and clinical diagnosis. A computer-based, eye-tracking study was designed to assess diagnostic accuracy and interpretation in stroke CT and MR imagery. Eight predetermined clinical cases, five images per case, were presented to participants (novices, trainee, and radiologists; n=8). The presence or absence of abnormalities was rated on a five-point Likert scale and their locations reported. Half cases of the cases were accompanied by clinical information; half were not, to assess the impact of information on observer performance. Results highlight differences in visual search patterns amongst novice, trainee and expert observers; the most marked differences occurred between novice readers and experts. Experts spent more time in challenging areas of interest (AOI) than novices and trainee, and were more confident unless a lesion was large and obvious. The time to first AOI fixation differed by size, shape and clarity of lesion. 'Time to lesion' dropped significantly when recognition appeared to occur between slices. The influence of clinical information was minimal.

2008-11-01

To study biometric measurements of emmetropic adult eyes with magnetic resonance imaging technology (MRI). MRI technology, with super-resolution, hyper-speed imaging and the integration of the thin-scanning layer, is applied to measure the three-dimensional biometric parameters of the eyeball. From January to December, 2003, emmetropic eyes from 31 normal Chinese adults (16 males and 15 females) aged from 18 to 32 years old (23.32 +/- 3.32) were successfully measured to obtain the volume of the eyeball and vitreous cavity; inner dimensions of the eye, including the anterior-posterior, vertical and horizontal diameters. The length of ocular axis was measured by A-echo too. Data was analyzed by SPSS 11.0 statistical software. The volume of the eyeball, anterior chamber, lens and the vitreous cavity is (6.013 +/- 0.449) ml, (0.348 +/- 0.020) ml, (0.183 +/- 0.015) ml, and (5.482 +/- 0.440) ml, respectively. The length of anterior-posterior diameter of the vitreous cavity is (16.008 +/- 0.707) mm. The ocular inner dimensions of horizontal, vertical and anterior-posterior planes were (22.455 +/- 0.983) mm, (23.290 +/- 0.815) mm and (22.619 +/- 0.912) mm, respectively. The length of the ocular axis is (23.10 +/- 0.92) mm (with MRI & Orbscan II) and (23.67 +/- 0.82) mm (with A-echo). The value of the ocular length in emmetropic eye measured with both MRI + Orbscan II and the (A-echo) in the present study is very close to the value of the Bennett-Rabbitts schematic eye (24.09 mm). MRI technology is valuable for obtaining more reliable and precise data in the study of ocular physiology and clinical ophthalmology.

Developing Curriculum to Help Students Explore the Geosciences' Cultural Relevance

Miller, G.; Schoof, J. T.; Therrell, M. D.

2011-12-01

Even though climate change and an unhealthy environment have a disproportionate affect on persons of color, there is a poor record of diversity in geoscience-related fields where researchers are investigating ways to improve the quality of the environment and human health. This low percentage of representation in the geosciences is equally troubling at the university where we are beginning the third and final year of a project funded through the National Science Foundation's (NSF) Opportunities to Enhance Diversity in the Geosciences (OEDG). The purpose of this project is to explore a novel approach to using the social sciences to help students, specifically underrepresented minorities, discover the geosciences' cultural relevance and consider a career in the earth, atmospheric, and ocean sciences. To date, over 800 college freshmen have participated in a design study to evaluate the curriculum efficacy of a geoscience reader. Over half of these participants are students of color. The reader we designed allows students to analyze multiple, and sometimes conflicting, sources such as peer-reviewed journal articles, political cartoons, and newspaper articles. The topic for investigation in the reader is the 1995 Chicago Heat Wave, a tragic event that killed over 700 residents. Students use this reader in a core university course required for entering freshmen with low reading comprehension scores on standardized tests. To support students' comprehension, evaluation, and corroboration of these sources, we incorporated instructional supports aligned with the principles of Universal Design for Learning (UDL), reciprocal teaching, historical reasoning, media literacy, and quantitative reasoning. Using a digital format allows students to access multiple versions of the sources they are analyzing and definitions of challenging vocabulary and scientific concepts. Qualitative and quantitative data collected from participating students and their instructors included focus

Topcon KR-1W visual quality analyzer was used to record the mean square the total high order corneal aberration, spherical aberration, comatic aberration and trefoil aberration of cornea with pupil diameters of 4mm and 6mm. Analysis of variance were used to compare the wavefront aberrations and the aberration values in the control group and in patients with diabetic retinopathy and with different degrees of dry eye. RESULTS: For 4mm and 6mm pupil diameters, nondiabetic retinopathy(NDRwith dry eye group, the nonproliferative diabetic retinopathy(NPDRwith dry eye group and proliferative diabetic retinopathy(PDRdry eye group had significantly increased tHOA, coma and trefoil compared with the contrast group(PPCONCLUSION: Dry eye of diabetic retinopathy with different degrees is closely related to the increase of wavefront aberration. Increased wavefront aberration may be one of the reasons to reduced visual quality in patients with diabetic retinopathy and with dry eye, and provide the basis for the decline of visual function of diabetic patients with dry eye.

Is inferring readers' literacy skills possible by analyzing their eye movements during text reading? This study used Support Vector Machines (SVM) to analyze eye movement data from 61 undergraduate students who read a multiple-paragraph, multiple-topic expository text. Forward fixation time, first-pass rereading time, second-pass fixation time, and regression path reading time on different regions of the text were provided as features. The SVM classification algorithm assisted in distinguishing high-literacy-skilled readers from low-literacy-skilled readers with 80.3 % accuracy. Results demonstrate the effectiveness of combining eye tracking and machine learning techniques to detect readers with low literacy skills, and suggest that such approaches can be potentially used in predicting other cognitive abilities.

From an interdisciplinary approach, the neurosciences (NSs) represent the junction of many fields (biology, chemistry, medicine, computer science, and psychology) and aim to explore the structural and functional aspects of the nervous system. Among modern neurophysiological methods that "measure" different processes of the human brain to salience stimuli, a special place belongs to eye tracking (ET). By detecting eye position, gaze direction, sequence of eye movement and visual adaptation during cognitive activities, ET is an effective tool for experimental psychology and neurological research. It provides a quantitative and qualitative analysis of the gaze, which is very useful in understanding choice behavior and perceptual decision making. In the high tech era, ET has several applications related to the interaction between humans and computers. Herein, ET is used to evaluate the spatial orienting of attention, the performance in visual tasks, the reactions to information on websites, the customer response to advertising, and the emotional and cognitive impact of various spurs to the brain.

Trompoukis, Constantinos; Kourkoutas, Dimitrios

2007-06-01

In distant eras, mythology was a form of expression used by many peoples. A study of the Greek myths reveals concealed medical knowledge, in many cases relating to the eye. An analysis was made of the ancient Greek texts for mythological references relating to an understanding of vision, visual abilities, the eye, its congenital and acquired abnormalities, blindness, and eye injuries and their treatment. The Homeric epics contain anatomical descriptions of the eyes and the orbits, and an elementary knowledge of physiology is also apparent. The concept of the visual field can be seen in the myth of Argos Panoptes. Many myths describe external eye disease ("knyzosis"), visual disorders (amaurosis), and cases of blinding that, depending on the story, are ascribed to various causes. In addition, ocular motility abnormalities, congenital anomalies (cyclopia), injuries, and special treatments, such as the "licking" method, are mentioned. The study of mythological references to the eye reveals reliable medical observations of the ancient Greeks, which are concealed within the myths.

Face exploration dynamics differentiate men and women.

Coutrot, Antoine; Binetti, Nicola; Harrison, Charlotte; Mareschal, Isabelle; Johnston, Alan

The human face is central to our everyday social interactions. Recent studies have shown that while gazing at faces, each one of us has a particular eye-scanning pattern, highly stable across time. Although variables such as culture or personality have been shown to modulate gaze behavior, we still don't know what shapes these idiosyncrasies. Moreover, most previous observations rely on static analyses of small-sized eye-position data sets averaged across time. Here, we probe the temporal dynamics of gaze to explore what information can be extracted about the observers and what is being observed. Controlling for any stimuli effect, we demonstrate that among many individual characteristics, the gender of both the participant (gazer) and the person being observed (actor) are the factors that most influence gaze patterns during face exploration. We record and exploit the largest set of eye-tracking data (405 participants, 58 nationalities) from participants watching videos of another person. Using novel data-mining techniques, we show that female gazers follow a much more exploratory scanning strategy than males. Moreover, female gazers watching female actresses look more at the eye on the left side. These results have strong implications in every field using gaze-based models from computer vision to clinical psychology.

Peer learning partnerships: exploring the experience of pre-registration nursing students.

Christiansen, Angela; Bell, Amelia

2010-03-01

This paper explores the impact of a peer learning initiative developed to facilitate, purposefully, mutually supportive learning relationships between student nurses in the practice setting. Finding effective strategies to support learning in the practice setting has been the focus of professional concern for a considerable time. In the UK clinical mentorship is seen as pivotal to ensuring fitness to practice; however, recent debate on the nature of learning has revealed the clinical workplace as a rich learning environment where learning occurs not only through hierarchical relationships, but also from a network of peer relationships. Formalising peer relationships through peer assisted learning is increasingly suggested as a strategy to support workplace learning and support novice students' transition to the clinical setting. Despite the developing literature in this field there is limited understanding about how students experience facilitated peer relationships. An interpretive qualitative design. Focus group interviews were used to collect interactive and situated discourse from nursing students who had recently participated in peer learning partnerships (n = 54). Narrative data were analysed thematically. Findings suggest that active support from a fellow student reduced the feelings of social isolation experienced by novice students in initial clinical placements, helping them to deal more effectively with the challenges faced and reducing the factors that have an impact on attrition. In addition, the reciprocity of the peer learning partnerships facilitated understanding of mentorship and created a heightened sense of readiness for registration and professional practice. Peer learning partnerships facilitated by mentors in clinical practice can support the transition to nursing for first year students and can help more experienced students gain a confidence and a heightened readiness for mentorship and registered practice.

Vincent Tinto

2017-07-01

Full Text Available The Feature for this issue Reflections on Student Persistence has been prepared by Professor Vincent Tinto, Distinguished University Professor Emeritus at Syracuse University, United States of America (USA and a longtime friend and supporter of STARS. Vincent explores the case for motivation to be considered as a significant aspect of the tertiary student psyche by drawing on theoretical frameworks, research and practical experiences related to the issue. He synthesises this extensive, detailed, rich but often somewhat impenetrable data into a trilogy of clear and credible key dimensions of the motivation construct student self efficacy, sense of belonging and perceived value of the curriculum. This interpretation of the literature is a personal but informed reflection and is a timely piece which highlights the breadth and profundity of the presentations at this year's conference in Adelaide, Australia where students in all their diversity are central to our focus on enhancing the student experience. In this opening article, Vincent refers directly to the STARS papers selected for this Conference issue of the Journal which also address the importance of student persistence, self-efficacy and building the sense of belonging within their own institutional communities (Fernandes, Ford, Rayner & Pretorius; Kahu, Nelson, & Picton; McFarlane, Spes-Skrbis & Taib; Naylor; Smallhorn. Echoing his position on social justice and his advocacy for underserved students, Vincent reminds us that educational equity gaps still exist, and he encourages us to see the issue of persistence through the eyes of the students to support their perseverance and completion and thereby help reduce educational disadvantage.

Wavefront Derived Refraction and Full Eye Biometry in Pseudophakic Eyes.

Directory of Open Access Journals (Sweden)

Xinjie Mao

Full Text Available To assess wavefront derived refraction and full eye biometry including ciliary muscle dimension and full eye axial geometry in pseudophakic eyes using spectral domain OCT equipped with a Shack-Hartmann wavefront sensor.Twenty-eight adult subjects (32 pseudophakic eyes having recently undergone cataract surgery were enrolled in this study. A custom system combining two optical coherence tomography systems with a Shack-Hartmann wavefront sensor was constructed to image and monitor changes in whole eye biometry, the ciliary muscle and ocular aberration in the pseudophakic eye. A Badal optical channel and a visual target aligning with the wavefront sensor were incorporated into the system for measuring the wavefront-derived refraction. The imaging acquisition was performed twice. The coefficients of repeatability (CoR and intraclass correlation coefficient (ICC were calculated.Images were acquired and processed successfully in all patients. No significant difference was detected between repeated measurements of ciliary muscle dimension, full-eye biometry or defocus aberration. The CoR of full-eye biometry ranged from 0.36% to 3.04% and the ICC ranged from 0.981 to 0.999. The CoR for ciliary muscle dimensions ranged from 12.2% to 41.6% and the ICC ranged from 0.767 to 0.919. The defocus aberrations of the two measurements were 0.443 ± 0.534 D and 0.447 ± 0.586 D and the ICC was 0.951.The combined system is capable of measuring full eye biometry and refraction with good repeatability. The system is suitable for future investigation of pseudoaccommodation in the pseudophakic eye.

Olsen, Knut; Walker, Constance E.; Smith, Blake; NOAO Data Lab Team

2018-01-01

We describe an activity aimed at teaching students how ultra-faint Milky Way dwarf galaxies are typically discovered: through filtering of optical photometric catalogs and cross-examination with deep images. The activity, which was developed as part of the Teen Astronomy Café program (https://teensciencecafe.org/cafes/az-teen-astronomy-cafe-tucson/), uses the NOAO Data Lab (http://datalab.noao.edu) and other professional-grade tools to lead high school students through exploration of the object catalog and images from the Survey of the Magellanic Stellar History (SMASH). The students are taught how to use images and color-magnitude diagrams to analyze and interpret stellar populations of increasing complexity, including those of star clusters and the Magellanic Clouds, and culminating with the discovery of the Hydra II ultra-faint dwarf galaxy. The tools and datasets presented allow the students to explore and discover other known stellar systems, as well as unknown candidate star clusters and dwarf galaxies. The ultimate goal of the activity is to give students insight into the methods of modern astronomical research and to allow them to participate in the thrill of discovery.

Full Text Available Abstract As FSL teacher educators look to respond to teachers’ concerns about the increasingly diverse student population in K-12 settings, empirical research may not always hold the answers—simply because there has not been much research on the topic. In an attempt to at least identify issues worthy of such empirical consideration and discussion within teacher education programs, this article explores the views of seven Grade 8 core French students who were members of an effective inclusive classroom. Drawing on the individual and focus group interview data from a larger case study of their teacher’s classroom, this article will identify two key themes that the students described as instrumental in the teacher’s attempts to be an effective, inclusive core French teacher. It is the goal of this article that these themes will help inform the decisions FSL teacher educators make about this topic within their programs.

To determine the prevalence of computer vision syndrome (CVS) and ergonomic practices among students in the Faculty of Medical Sciences at The University of the West Indies (UWI), Jamaica. A cross-sectional study was done with a self-administered questionnaire. Four hundred and nine students participated; 78% were females. The mean age was 21.6 years. Neck pain (75.1%), eye strain (67%), shoulder pain (65.5%) and eye burn (61.9%) were the most common CVS symptoms. Dry eyes (26.2%), double vision (28.9%) and blurred vision (51.6%) were the least commonly experienced symptoms. Eye burning (P = .001), eye strain (P = .041) and neck pain (P = .023) were significantly related to level of viewing. Moderate eye burning (55.1%) and double vision (56%) occurred in those who used handheld devices (P = .001 and .007, respectively). Moderate blurred vision was reported in 52% who looked down at the device compared with 14.8% who held it at an angle. Severe eye strain occurred in 63% of those who looked down at a device compared with 21% who kept the device at eye level. Shoulder pain was not related to pattern of use. Ocular symptoms and neck pain were less likely if the device was held just below eye level. There is a high prevalence of Symptoms of CVS amongst university students which could be reduced, in particular neck pain and eye strain and burning, with improved ergonomic practices. © 2017 John Wiley & Sons Ltd.

To analyse web-based training in ophthalmology offered by German university eye hospitals. In January 2010 the websites of all 36 German university hospitals were searched for information provided for visitors, students and doctors alike. We evaluated the offer in terms of quantity and quality. All websites could be accessed at the time of the study. 28 pages provided information for students and doctors, one page only for students, three exclusively for doctors. Four pages didn't offer any information for these target groups. The websites offered information on events like congresses or students curricular education, there were also material for download for these events or for other purposes. We found complex e-learning-platforms on 9 pages. These dealt with special ophthalmological topics in a didactic arrangement. In spite of the extensive possibilities offered by the technology of Web 2.0, many conceivable tools were only rarely made available. It was not always possible to determine if the information provided was up-to-date, very often the last actualization of the content was long ago. On one page the date for the last change was stated as 2004. Currently there are 9 functional e-learning-applications offered by German university eye hospitals. Two additional hospitals present links to a project of the German Ophthalmological Society. There was a considerable variation in quantity and quality. No website made use of crediting successful studying, e.g. with CME-points or OSCE-credits. All German university eye hospitals present themselves in the World Wide Web. However, the lack of modern, technical as well as didactical state-of-the-art learning applications is alarming as it leaves an essential medium of today's communication unused.

2016-05-01

First-generation college students (students for whom neither parent has a 4-year college degree) earn lower grades and worry more about whether they belong in college, compared with continuing-generation students (who have at least 1 parent with a 4-year college degree). We conducted a longitudinal follow-up of participants from a study in which a values-affirmation intervention improved performance in a biology course for first-generation college students, and found that the treatment effect on grades persisted 3 years later. First-generation students in the treatment condition obtained a GPA that was, on average, .18 points higher than first-generation students in the control condition, 3 years after values affirmation was implemented (Study 1A). We explored mechanisms by testing whether the values-affirmation effects were predicated on first-generation students reflecting on interdependent values (thus affirming their values that are consistent with working-class culture) or independent values (thus affirming their values that are consistent with the culture of higher education). We found that when first-generation students wrote about their independence, they obtained higher grades (both in the semester in which values affirmation was implemented and in subsequent semesters) and felt less concerned about their background. In a separate laboratory experiment (Study 2) we manipulated the extent to which participants wrote about independence and found that encouraging first-generation students to write more about their independence improved their performance on a math test. These studies highlight the potential of having FG students focus on their own independence. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

An exploration of student midwives' language to describe non-formal learning in professional practice.

Science.gov (United States)

Finnerty, Gina; Pope, Rosemary

2005-05-01

The essence of non-formal learning in midwifery practice has not been previously explored. This paper provides an in-depth analysis of the language of a sample of student midwives' descriptions of their practice learning in a range of clinical settings. The students submitted audio-diaries as part of a national study (Pope, R., Graham. L., Finnerty. G., Magnusson, C. 2003. An investigation of the preparation and assessment for midwifery practice within a range of settings. Project Report. University of Surrey). Participants detailed their learning activities and support obtained whilst working with their named mentors for approximately 10 days or shifts. The rich audio-diary data have been analysed using Discourse Analysis. A typology of non-formal learning (Eraut, M. 2000. Non-formal learning and implicit knowledge in professional work. British Journal of Educational Psychology 70, 113-136) has been used to provide a framework for the analysis. Non-formal learning is defined as any learning which does not take place within a formally organised learning programme (Eraut, M. 2000. Non-formal learning and implicit knowledge in professional work. British Journal of Educational Psychology 70, 113-136). Findings indicate that fear and ambiguity hindered students' learning. Recommendations include the protection of time by mentors within the clinical curriculum to guide and supervise students in both formal and non-formal elements of midwifery practice. This paper will explore the implications of the findings for practice-based education.

The role of eye protection in work-related eye injuries.

Science.gov (United States)

Fong, L P; Taouk, Y

1995-05-01

A recent survey of general hospitals by the Victorian Injury Surveillance System found that ocular trauma represented 15% of work-related injuries. As circumstances surrounding occupational eye injuries have been poorly documented previously, their associations to occupation, industry and work-safety practices, including safety eyewear use, need to be identified to develop appropriate preventive strategies for high-risk groups. From a prospective cross-sectional survey of all eye injuries treated at the Royal Victorian Eye and Ear Hospital, work-related cases were analysed for demographic, occupational and safety eye-wear information. Hospital-based data were supplemented by information from WorkCover Authorities and Labour Force statistics to derive incidence and cost estimates. There were 9390 eye injuries during the 18-month survey period; 42% (n=3923) of total and 29% (n=52) of penetrating ocular injuries occurred at work. The most frequently injured were metal, automotive and building trades workers grinding and drilling (41% of outpatients) and hammering (53% of penetrating eye injuries). Automotive workers had the highest frequency for penetrating injuries, and most were exposed to hammering and were also the least likely to wear safety eye-wear. Eye injuries are frequent (10% of work-related injuries) and highly preventable by the correct use of safety eye-wear, a cost-effective intervention that may result in cost savings of $59 million for work-type activities in the occupational and domestic settings in Australia each year.

Mazen El-Hammadi

2013-09-01

Full Text Available This study aimed to assess pharmacy students’ knowledge about doping substances used in sport, explore their attitudes toward doping and investigate their misuse of doping drugs. A questionnaire was developed and employed to collect data from bachelor of pharmacy (BPharm students at the International University for Science and Technology (IUST. Two-hundred and eighty students participated in this self-administrated, paper-based survey. Around 90% of the students did not appear to know that narcotics, β-blockers and diuretics were used in sport as doping agents. Additionally, proportions between 60% and 80% considered vitamins, energy drinks and amino acids as substances that possess performance-enhancing effects. The main reason for doping, based on students’ response, was to improve muscular body appearance. The vast majority of students agreed that pharmacists should play a major role in promoting awareness about risks of doping. While students showed negative attitudes toward doping, approximately 15% of them, primarily males, had already tried a doping drug or might do so in the future. More than 60% of the students believed that sports-mates and friends are the most influential in encouraging them to take a doping agent. The study highlights the need to provide pharmacy students with advanced theoretical background and practical training concerning doping. This can be achieved by adopting simple, but essential, changes to the current curricula.

More than meets the eye: the role of self-identity in decoding complex emotional states.

Stevenson, Michael T; Soto, José A; Adams, Reginald B

2012-10-01

Folk wisdom asserts that "the eyes are the window to the soul," and empirical science corroborates a prominent role for the eyes in the communication of emotion. Herein we examine variation in the ability to "read" the eyes of others as a function of social group membership, employing a widely used emotional state decoding task: "Reading the Mind in Eyes." This task has documented impaired emotional state decoding across racial groups, with cross-race performance on par with that previously reported as a function of autism spectrum disorders. The present study extended this work by examining the moderating role of social identity in such impairments. For college students more highly identified with their university, cross-race performance differences were not found for judgments of "same-school" eyes but remained for "rival-school" eyes. These findings suggest that impaired emotional state decoding across groups may thus be more amenable to remediation than previously realized.

Purpose. We present a new method to evaluate the accuracy of an eye tracker based eye localization system. Measuring the accuracy of an eye tracker's primary intention, the estimated point of gaze, is usually done with volunteers and a set of fixation points used as ground truth. However, verifying the accuracy of the location estimate of a volunteer's eye center in 3D space is not easily possible. This is because the eye center is an intangible point hidden by the iris. Methods. We evaluate ...

Dry eye disease has become an important health problem. A lack of concordance between self-reported symptoms and the outcome of dry eye examinations has raised questions about dry eye disease. To explore the association between subjective happiness and objective and subjective symptoms of dry eye disease. The study adopted a cross-sectional design. All the employees of a company in Osaka, Japan. 672 Japanese office workers using Visual Display Terminals (age range: 26-64 years). The dry eye measurement tools included the Schirmer test, conjunctivocorneal staining, the tear film break-up time, as well as the administration of a dry eye symptoms questionnaire. Happiness was measured by the Subjective Happiness Scale. Dry eye examination parameters, dry eye symptoms questionnaires, and the Subjective Happiness Scale score. Of the 672 workers, 561 (83.5%) completed the questionnaires and examinations. The mean Subjective Happiness Scale score was 4.91 (SD = 1.01). This score was inversely correlated with the dry eye symptom score (r = -0.188, p happiness was the lowest in the group without objective results, but reported subjective symptoms of dry eyes (p happiness and self-reported symptoms of dry eyes. Findings of this study revealed a new perspective on dry eye disease, including the potential for innovative treatments of a specific population with dry eye disease.

Teaching and Learning Science Through Song: Exploring the experiences of students and teachers

Science.gov (United States)

Governor, Donna; Hall, Jori; Jackson, David

2013-12-01

This qualitative, multi-case study explored the use of science-content music for teaching and learning in six middle school science classrooms. The researcher sought to understand how teachers made use of content-rich songs for teaching science, how they impacted student engagement and learning, and what the experiences of these teachers and students suggested about using songs for middle school classroom science instruction. Data gathered included three teacher interviews, one classroom observation and a student focus-group discussion from each of six cases. The data from each unit of analysis were examined independently and then synthesized in a multi-case analysis, resulting in a number of merged findings, or assertions, about the experience. The results of this study indicated that teachers used content-rich music to enhance student understanding of concepts in science by developing content-based vocabulary, providing students with alternative examples and explanations of concepts, and as a sense-making experience to help build conceptual understanding. The use of science-content songs engaged students by providing both situational and personal interest, and provided a mnemonic device for remembering key concepts in science. The use of songs has relevance from a constructivist approach as they were used to help students build meaning; from a socio-cultural perspective in terms of student engagement; and from a cognitive viewpoint in that in these cases they helped students make connections in learning. The results of this research have implications for science teachers and the science education community in developing new instructional strategies for the middle school science classroom.

Psychopathic traits affect the visual exploration of facial expressions.

Science.gov (United States)

Boll, Sabrina; Gamer, Matthias

2016-05-01

Deficits in emotional reactivity and recognition have been reported in psychopathy. Impaired attention to the eyes along with amygdala malfunctions may underlie these problems. Here, we investigated how different facets of psychopathy modulate the visual exploration of facial expressions by assessing personality traits in a sample of healthy young adults using an eye-tracking based face perception task. Fearless Dominance (the interpersonal-emotional facet of psychopathy) and Coldheartedness scores predicted reduced face exploration consistent with findings on lowered emotional reactivity in psychopathy. Moreover, participants high on the social deviance facet of psychopathy ('Self-Centered Impulsivity') showed a reduced bias to shift attention towards the eyes. Our data suggest that facets of psychopathy modulate face processing in healthy individuals and reveal possible attentional mechanisms which might be responsible for the severe impairments of social perception and behavior observed in psychopathy.

Premotor neurons encode torsional eye velocity during smooth-pursuit eye movements

Science.gov (United States)

Angelaki, Dora E.; Dickman, J. David

2003-01-01

Responses to horizontal and vertical ocular pursuit and head and body rotation in multiple planes were recorded in eye movement-sensitive neurons in the rostral vestibular nuclei (VN) of two rhesus monkeys. When tested during pursuit through primary eye position, the majority of the cells preferred either horizontal or vertical target motion. During pursuit of targets that moved horizontally at different vertical eccentricities or vertically at different horizontal eccentricities, eye angular velocity has been shown to include a torsional component the amplitude of which is proportional to half the gaze angle ("half-angle rule" of Listing's law). Approximately half of the neurons, the majority of which were characterized as "vertical" during pursuit through primary position, exhibited significant changes in their response gain and/or phase as a function of gaze eccentricity during pursuit, as if they were also sensitive to torsional eye velocity. Multiple linear regression analysis revealed a significant contribution of torsional eye movement sensitivity to the responsiveness of the cells. These findings suggest that many VN neurons encode three-dimensional angular velocity, rather than the two-dimensional derivative of eye position, during smooth-pursuit eye movements. Although no clear clustering of pursuit preferred-direction vectors along the semicircular canal axes was observed, the sensitivity of VN neurons to torsional eye movements might reflect a preservation of similar premotor coding of visual and vestibular-driven slow eye movements for both lateral-eyed and foveate species.

Burning Eye Syndrome: Do Neuropathic Pain Mechanisms Underlie Chronic Dry Eye?

Science.gov (United States)

Kalangara, Jerry P; Galor, Anat; Levitt, Roy C; Felix, Elizabeth R; Alegret, Ramon; Sarantopoulos, Constantine D

2016-04-01

Dry eye is a multi-factorial disorder that manifests with painful ocular symptoms and visual disturbances, which can only be partly attributed to tear dysfunction. This disorder may also involve neuroplasticity in response to neuronal injury. This review will emphasize the key characteristics of dry eye pain and its pathologic mechanisms, making the argument that a subset of dry eye represents a neuropathic pain disorder of the eye, more appropriately called "burning eye syndrome." A literature review was conducted using a PubMed search focusing on dry eye, corneal nociception, and neuropathic pain. Articles were reviewed and those discussing clinical course, pathophysiology, and neuronal regulation of chronic ocular pain as related to dry eye were summarized. We found that there is a discordance between ocular pain and dryness on the ocular surface. Although tear dysfunction may be one of the initial insults, its persistence may be associated with repeated ocular sensory nerve injury leading to an acute-to-chronic pain transition associated with neuropathologic changes (peripheral and central sensitization), neuronal dysfunction, and spontaneous ocular pain. Dry eye is becoming a major health concern due to its increasing incidence, significant morbidity, and economic burden. Recent evidence suggests that a subset of dry eye may be better represented as a chronic neuropathic pain disorder due to its features of dysesthesia, spontaneous pain, allodynia, and hyperalgesia. Future therapies targeted at the underlying neuroplasticity may yield improved efficacy for patients with this subset of dry eye, which we term "burning eye syndrome." © 2015 American Academy of Pain Medicine.

2010-12-01

MOSAIC unit begins with a series of activities and lessons designed to take advantage of the large data sets MOSAIC is collecting all the time to teach students about measurement, uncertainty, and data analysis. The curriculum develops an intuitive approach to thinking about numbers in science, focusing on both implicit and explicit expressions of uncertainty. Our teaching unit concludes with a final research project to provide students with the opportunity to pursue an area of interest within mesospheric ozone. This project is conceived in such a way that it can be as self-directed as a teacher or student needs. Given current concern for the state of our atmosphere and ozone, MOSAIC provides a unique opportunity for student engagement in an area of scientific research that has not been extensively explored. MOSAIC data can be compared with online resources for other atmospheric, astronomical, or geophysical data, and have been analyzed for the effects of such variables as seasonal and solar flux variations, lunar phases, shuttle and rocket launches, and sudden stratospheric warming events.

Few studies have addressed the challenges associated with international students as they adapt to studying medicine in a new host country. Higher level institutions have increasing numbers of international students commencing programmes. This paper explores the experiences of a cohort of students in the early years of medical school in Ireland, where a considerable cohort are from an international background. A mixed exploratory sequential study design was carried out with medical students in the preclinical component of a five year undergraduate programme. Data for the qualitative phase was collected through 29 semi-structured interviews using the peer interview method. Thematic analysis from this phase was incorporated to develop an online questionnaire combined with components of the Student Adaptation to College Questionnaire and Student Integration Questionnaire. First year students were anonymously surveyed online. The Mokken Scaling procedure was used to investigate the students' experiences, both positive and negative. Three main themes are identified; social adjustment, social alienation and cultural alienation. The response rate for the survey was 49% (467 Respondents). The Mokken Scaling method identified the following scales (i) Positive experience of student life; (ii) Social alienation, which comprised of negative items about feeling lonely, not fitting in, being homesick and (iii) Cultural alienation, which included the items of being uncomfortable around cultural norms of dress and contact between the sexes. With the threshold set to H = 0.4. Subscales of the positive experiences of student life scale are explored further. Overall student adjustment to a western third level college was good. Students from regions where cultural distance is greatest reported more difficulties in adjusting. Students from these regions also demonstrate very good adaptation. Some students from the host country and more similar cultural backgrounds were also

Exploring the Relationship Between Students with Accommodations and Instructor Self-Efficacy in Complying with Accommodations

Directory of Open Access Journals (Sweden)

Anna M. Wright

2017-06-01

Full Text Available The willingness and flexibility of university instructors to comply with and provide accommodations for students with disabilities is critical to academic success. The authors examine how communication between students needing accommodations and university instructors impacts instructor self-efficacy, or instructors’ perception that they can meet the accommodation. Specifically, the authors’ explored the relationship between student self-disclosure of a disability and instructor empathy, flexibility, and self-efficacy in meeting student accommodation needs. Results revealed that the more a student self-discloses about a needed accommodation, the more self-efficacy an instructor has in making that accommodation. For the low-disclosure condition, empathy and flexibility were both significant predictors of self-efficacy, whereas, for the high-disclosure condition, only flexibility was a significant predictor of self-efficacy. Finally, instructors’ levels of empathy and flexibility both decreased after reading both the high and low self-disclosure scenarios.

Giving children space: A phenomenological exploration of student experiences in space science inquiry

Science.gov (United States)

Horne, Christopher R.

This study explores the experiences of 4th grade students in an inquiry-based space science classroom. At the heart of the study lies the essential question: What is the lived experience of children engaged in the process of space science inquiry? Through the methodology of phenomenological inquiry, the author investigates the essence of the lived experience of twenty 4th grade students as well as the reflections of two high school students looking back on their 4th grade space science experience. To open the phenomenon more deeply, the concept of space is explored as an overarching theme throughout the text. The writings of several philosophers including Martin Heidegger and Hans-Georg Gadamer are opened up to understand the existential aspects of phenomenology and the act of experiencing the classroom as a lived human experience. The methodological structure for the study is based largely on the work of Max van Manen (2003) in his seminal work, Researching Lived Experience, which describes a structure of human science research. A narrative based on classroom experiences, individual conversations, written reflections, and group discussion provides insight into the students' experiences. Their stories and thoughts reveal the themes of activity , interactivity, and "inquiractivity," each emerging as an essential element of the lived experience in the inquiry-based space science classroom. The metaphor of light brings illumination to the themes. Activity in the classroom is associated with light's constant and rapid motion throughout the Milky Way and beyond. Interactivity is seen through students' interactions just as light's reflective nature is seen through the illumination of the planets. Finally, inquiractivity is connected to questioning, the principal aspect of the inquiry-based classroom just as the sun is the essential source of light in our solar system. As the era of No Child Left Behind fades, and the next generation of science standards emerge, the

Exploring the transition of undergraduate medical students into a clinical clerkship using organizational socialization theory.

Atherley, Anique E; Hambleton, Ian R; Unwin, Nigel; George, Colette; Lashley, Paula M; Taylor, Charles G

2016-04-01

Transitions in medical education are emotionally and socially dynamic; this may affect learning. Students transitioning from preclinical to clinical training may experience negative consequences. Less is understood about students' experiences during transitions within clinical training and influential factors. The authors used organizational socialization theory to explore a transition within the clinical years. Final-year medical students experienced a nine-week internal medicine clerkship; willing students participated. Students (n = 101; 97 %) completed a questionnaire with open-ended questions at the beginning and end of the clerkship and participated in six consecutive focus groups, until data saturation occurred (n = 37). Data were thematically analyzed. Socialization was challenging. Many students experienced difficulty developing relationships with team members. Students with a positive attitude experienced a smoother transition. Many students were uncertain of their roles, concerned about the workload and desired guidance to meet clerkship demands. This transition resulted in varied outcomes from enjoyment, increased confidence and student development through to disinterest. Transitions within clinical training are complex. Faculty should focus on adequate socialization in a new clerkship as this may facilitate a smoother transition. This may necessitate orientations, staff training, and formal student support. Further research is needed on the impact of these recommendations on learning and well-being.

Relationship between abstract thinking and eye gaze pattern in patients with schizophrenia

Science.gov (United States)

2014-01-01

Background Effective integration of visual information is necessary to utilize abstract thinking, but patients with schizophrenia have slow eye movement and usually explore limited visual information. This study examines the relationship between abstract thinking ability and the pattern of eye gaze in patients with schizophrenia using a novel theme identification task. Methods Twenty patients with schizophrenia and 22 healthy controls completed the theme identification task, in which subjects selected which word, out of a set of provided words, best described the theme of a picture. Eye gaze while performing the task was recorded by the eye tracker. Results Patients exhibited a significantly lower correct rate for theme identification and lesser fixation and saccade counts than controls. The correct rate was significantly correlated with the fixation count in patients, but not in controls. Conclusions Patients with schizophrenia showed impaired abstract thinking and decreased quality of gaze, which were positively associated with each other. Theme identification and eye gaze appear to be useful as tools for the objective measurement of abstract thinking in patients with schizophrenia. PMID:24739356

Motion Estimation Using the Single-row Superposition-type Planar Compound-like Eye

Directory of Open Access Journals (Sweden)

Gwo-Long Lin

2007-06-01

Full Text Available How can the compound eye of insects capture the prey so accurately andquickly? This interesting issue is explored from the perspective of computer vision insteadof from the viewpoint of biology. The focus is on performance evaluation of noiseimmunity for motion recovery using the single-row superposition-type planar compound-like eye (SPCE. The SPCE owns a special symmetrical framework with tremendousamount of ommatidia inspired by compound eye of insects. The noise simulates possibleambiguity of image patterns caused by either environmental uncertainty or low resolutionof CCD devices. Results of extensive simulations indicate that this special visualconfiguration provides excellent motion estimation performance regardless of themagnitude of the noise. Even when the noise interference is serious, the SPCE is able todramatically reduce errors of motion recovery of the ego-translation without any type offilters. In other words, symmetrical, regular, and multiple vision sensing devices of thecompound-like eye have statistical averaging advantage to suppress possible noises. Thisdiscovery lays the basic foundation in terms of engineering approaches for the secret of thecompound eye of insects.

A long-standing question is whether neoblasts directly sense and respond to the identity of missing tissues during regeneration. We used the eye to investigate this question. Surprisingly, eye removal was neither sufficient nor necessary for neoblasts to increase eye progenitor production. Neoblasts normally increase eye progenitor production following decapitation, ...

Full Text Available College student-athletes (SAs may experience difficulties while transitioning from college, which could reduce their overall wellness. However, it is essential to understand positive transition experiences and outcomes, as this can guide future research and intervention efforts. The purpose of this study was to explore the factors that led to higher levels of wellness in former SAs. Semi-structured interviews guided by the Indivisible Self Model were completed with former SAs (n = 12. Overall, participants displayed high levels of wellness - most prominently in terms of work and exercise. Many SAs perceived their current wellness was equal, if not better compared to when they were SAs. These results illustrate examples of successful transitions of former SAs, which can guide future research and interventions.

Kourkoumelis, Nikolaos; Tzaphlidou, Margaret

2011-03-01

Biometrics has become an emerging field of technology due to its intrinsic security features concerning the identification of individuals by means of measurable biological characteristics. Two of the most promising biometric modalities are iris and retina recognition, which primarily use nonionizing radiation in the infrared region. Illumination of the eye is achieved by infrared light emitting diodes (LEDs). Even if few LED sources are capable of causing direct eye damage as they emit incoherent light, there is a growing concern about the possible use of LED arrays that might pose a potential threat. Exposure to intense coherent infrared radiation has been proven to have significant effects on living tissues. The purpose of this study is to explore the biological effects arising from exposing the eye to near infrared radiation with reference to international legislation.

Dry eye is a common problem in Ophthalmology and may occur for many reasons including Sjogren's syndrome (SS). Recent studies have identified autoantibodies, anti-salivary gland protein 1 (SP1), anti-carbonic anhydrase 6 (CA6) and anti-parotid secretory protein (PSP), which occur early in the course of SS. The current studies were designed to evaluate how many patients with idiopathic dry eye and no evidence of systemic diseases from a dry eye practice have these autoantibodies. Patients from a dry eye clinic and normal controls were assessed by Schirmer's test for tear flow. Sera were assessed for autoantibodies using ELISA assays. Statistics was performed with Prism 7 software and student's unpaired t test. In this study 60% of the dry eye patients expressed one of these autoantibodies. Only 30% expressed one of the autoantibodies associated with long-standing SS, which are included in the diagnostic criteria for SS, anti-Ro and anti-La. Patients with disease for less than 2 years and mild dry eyes did not express anti-Ro or anti-La, while 25% expressed anti-SP1. Similar observations, with smaller numbers, were made when patients had not only dry eye but also dry mouth. Antibodies to SP1, CA6 and PSP occur in some patients with idiopathic dry eyes. Further studies will be needed to determine how many of these patients go on to develop systemic manifestations of SS. Testing for these autoantibodies may allow early recognition of patients with SS. This will lead to improved management of the patients and the development of new strategies to maintain normal lacrimal and salivary gland function in patients with SS.

Full Text Available Abstract Background We describe corneal endothelial cell density and morphology in normal Iranian eyes and compare endothelial cell characteristics in the Iranian population with data available in the literature for American and Indian populations. Methods Specular microscopy was performed in 525 eyes of normal Iranian people aged 20 to 85 years old. The studied parameters including mean endothelial cell density (MCD, mean cell area (MCA and coefficient of variation (CV in cell area were analyzed in all of the 525 eyes. Results MCD was 1961 ± 457 cell/mm2 and MCA was 537.0 ± 137.4 μm2. There was no statistically significant difference in MCD, MCA and CV between genders (Student t-test, P = 0.85, P = 0.97 and P = 0.15 respectively. There was a statistically significant decrease in MCD with age (P r = -0.64. The rate of cell loss was 0.6% per year. There was also a statistically significant increase in MCA (P r = 0.56 and CV (P r = 0.30 from 20 to 85 years of age. Conclusion The first normative data for the endothelium of Iranian eyes seems to confirm that there are no differences in MCD, MCA and CV between genders. Nevertheless, the values obtained in Iranian eyes seem to be different to those reported by the literature in Indian and American populations.

Searching for Chaos Evidence in Eye Movement Signals

Directory of Open Access Journals (Sweden)

Katarzyna Harezlak

2018-01-01

Full Text Available Most naturally-occurring physical phenomena are examples of nonlinear dynamic systems, the functioning of which attracts many researchers seeking to unveil their nature. The research presented in this paper is aimed at exploring eye movement dynamic features in terms of the existence of chaotic nature. Nonlinear time series analysis methods were used for this purpose. Two time series features were studied: fractal dimension and entropy, by utilising the embedding theory. The methods were applied to the data collected during the experiment with “jumping point” stimulus. Eye movements were registered by means of the Jazz-novo eye tracker. One thousand three hundred and ninety two (1392 time series were defined, based on the horizontal velocity of eye movements registered during imposed, prolonged fixations. In order to conduct detailed analysis of the signal and identify differences contributing to the observed patterns of behaviour in time scale, fractal dimension and entropy were evaluated in various time series intervals. The influence of the noise contained in the data and the impact of the utilized filter on the obtained results were also studied. The low pass filter was used for the purpose of noise reduction with a 50 Hz cut-off frequency, estimated by means of the Fourier transform and all concerned methods were applied to time series before and after noise reduction. These studies provided some premises, which allow perceiving eye movements as observed chaotic data: characteristic of a space-time separation plot, low and non-integer time series dimension, and the time series entropy characteristic for chaotic systems.

Engineers' Responsibilities for Global Electronic Waste: Exploring Engineering Student Writing Through a Care Ethics Lens.

Science.gov (United States)

Campbell, Ryan C; Wilson, Denise

2017-04-01

This paper provides an empirically informed perspective on the notion of responsibility using an ethical framework that has received little attention in the engineering-related literature to date: ethics of care. In this work, we ground conceptual explorations of engineering responsibility in empirical findings from engineering student's writing on the human health and environmental impacts of "backyard" electronic waste recycling/disposal. Our findings, from a purposefully diverse sample of engineering students in an introductory electrical engineering course, indicate that most of these engineers of tomorrow associated engineers with responsibility for the electronic waste (e-waste) problem in some way. However, a number of responses suggested attempts to deflect responsibility away from engineers towards, for example, the government or the companies for whom engineers work. Still other students associated both engineers and non-engineers with responsibility, demonstrating the distributed/collective nature of responsibility that will be required to achieve a solution to the global problem of excessive e-waste. Building upon one element of a framework for care ethics adopted from the wider literature, these empirical findings are used to facilitate a preliminary, conceptual exploration of care-ethical responsibility within the context of engineering and e-waste recycling/disposal. The objective of this exploration is to provide a first step toward understanding how care-ethical responsibility applies to engineering. We also hope to seed dialogue within the engineering community about its ethical responsibilities on the issue. We conclude the paper with a discussion of its implications for engineering education and engineering ethics that suggests changes for educational policy and the practice of engineering.

Exploring the Relationship between Students' Understanding of Conventional Time and Deep (Geologic) Time

Science.gov (United States)

Cheek, Kim A.

2013-07-01

Many geologic processes occur in the context of geologic or deep time. Students of all ages demonstrate difficulty grasping this fundamental concept which impacts their ability to acquire other geoscience concepts. A concept of deep time requires the ability to sequence events on an immense temporal scale (succession) and to judge the durations of geologic processes based on the rates at which they occur. The twin concepts of succession and duration are the same ideas that underlie a concept of conventional time. If deep time is an extension of conventional time and not qualitatively different from it, students should display similar reasoning patterns when dealing with analogous tasks over disparate temporal periods. Thirty-five US students aged 13-24 years participated in individual task-based interviews to ascertain how they thought about succession and duration in conventional and deep time. This is the first attempt to explore this relationship in the same study in over 30 years. Most students successfully completed temporal succession tasks, but there was greater variability in responses on duration tasks. Conventional time concepts appear to impact how students reason about deep time. The application of spatial reasoning to temporal tasks sometimes leads to correct responses but in other instances does not. Implications for future research and teaching strategies are discussed.

Salivation induced better lacrimal gland function in dry eyes.

The dry eye syndrome is a common eye symptom causing blurry vision. To meet the demand of the modem world students and professionals are compelled to expose themselves to the computer screen for long stretch of time, which is one of the causes of dry eye. It is not always feasible to instil eyes with artificial tears time to time to protect them from dryness. Rather to adopt any simple physiological process associated with optimum lacrimation is a better option to keep eyes moist during computer works. Volunteers (n = 22) having mild dry eyes participated in this study. Tear production was assessed by Schirmer test by keeping Schirmer strip on ocular surface for 5 minutes and recording the length of the moistened area. Then the subject was allowed to keep a piece of lopsy candy (a sour fruit pulp mixed with sugar that is sweet and sour in taste) in mouth for 5 minutes that caused salivation. During salivation, again tear production was assessed. [It was standardized in such a way that, the length of the moistened strip will be 25 - 30 mm for normal eyes, 15 - 10 mm for dry eye, 06 - 10 mm for mild dry eye, 02 - 05 mm for moderate dryness and 00 - 01 mm for severe dry eye.] Tear production was found to be increased significantly (supported by increased length of moistened area of Schirmer strip) during salivation especially in dry eye in all volunteers. The lacrimal gland is the major contributor to the aqueous layer of the tear film which consists of water, electrolytes and proteins; secretion of which are under tight neural control. Anticholinergic agents play an important role in ocular dryness because of hypo-secretion. The sensory root of facial nucleus contains efferent preganglionic parasympathetic fibers for submandibular and sublingual salivary gland and lacrimal gland. The sensory root conveys gustatory fibers from the presulcul area (anterior two-third) of the tongue via the chorda tympani and via the palatine and greater petrosal nerve, taste fibers from

To determine how people attending outreach eye care clinics in Papua New Guinea (PNG) perceive eye health and eye health services. An interview-based questionnaire was administrated to a convenience sample of 614 adult participants across four provinces and perceptions of eye health and eye health services were recorded. Presenting and near visual acuity were measured and cause of visual impairment (VI) determined. In this sample, 113/614 participants (18.4%) presented with distance VI, 16 (2.6%) with distance blindness, and 221 (47.6%) with near VI. Older participants and those with near VI were more likely to indicate that it is hard to have an eye examination due to travel time, lack of transport and transport costs. Female participants and those from underserved areas were more likely to report shame and fear of jealousy from others when asked about their attitudes towards spectacles. Participants reporting that they were willing to pay higher amounts for testing and spectacles/treatment also reported higher education levels, higher household incomes and were more likely to be male. A quarter of participants (25.9%) indicated that they did not like having an eye examination because their reading and writing was poor. People attending outreach eye care clinics in PNG reported finding it difficult to attend eye health services due to transport difficulties and anticipated high costs. Negative attitudes towards spectacles were also prevalent, and negative perceptions appeared more frequently among older participants and those with less education.

in Australia, models of maternity care that offer women continuity of care with a known midwife have been promoted. Little is known about the intentions of the future midwifery workforce to work in such models. This study aimed to explore midwifery students' views and experiences of caseload midwifery and their work intentions in relation to the caseload model following graduation. cross-sectional survey. Victoria, Australia. 129 midwifery students representing all midwifery course pathways (Post Graduate Diploma, Bachelor of Midwifery, Bachelor of Nursing/Bachelor of Midwifery) in Victoria. midwifery students from all course pathways considered that continuity of care is important to women and indicated that exposure to continuity models during their course was very positive. Two-thirds of the students (67%) considered that the continuity experiences made them want to work in a caseload model; only 5% reported that their experiences had discouraged them from continuity of care work in the future. Most wanted a period of consolidation to gain experience as a midwife prior to commencing in the caseload model. Perceived barriers to caseload work were being on-call, and challenges in regard to work/life balance and family commitments. midwifery students in this study were very positive about caseload midwifery and most would consider working in caseload after a period of consolidation. Continuity of care experiences during students' midwifery education programmes appeared to provide students with insight and understanding of continuity of care for both women and midwives. Further research should explore what factors influence students' future midwifery work, whether or not their plans are fulfilled, and whether or not the caseload midwifery workforce can be sustained.

There is a huge need for the availability of transplantable donor corneas worldwide to reduce the burden of corneal blindness due to corneal opacity. Voluntary eye donation depends on the awareness levels of various stakeholders in the community. This study aimed to assess the awareness level regarding eye donation among various stakeholders in Srikakulam district in the state of Andhra Pradesh, India. 355 subjects were selected from the district using multi stage random sampling. A pre tested semi structured questionnaire was used to collect information regarding each individual's awareness, knowledge, and perception regarding eye donation. Each response was scored individually and a total score was calculated. Univariate and multivariate regression analysis was used to determine the factors associated with willingness towards eye donation and increased awareness levels. Of the 355 subjects interviewed, 192 (54%) were male and 163 (46%) were female. The mean age of the stakeholders was 35.9 years (SD ±16.1) and all the study subjects were literate. Ninety-three percent of subjects were aware of the concept of eye donation. Knowledge levels were similar among the teaching community and persons engaged in social service, but lower among students (p stakeholders, there was considerable ambiguity regarding whether persons currently wearing spectacles or suffering from a chronic illnesses could donate their eyes. Older age group (p stakeholders in Srikakulam district in India. The services of stakeholders could be utilized, in conjunction with other community based eye donation counselors, to promote awareness regarding eye donation among the general population.

Allen, Lauren K; Bhattacharyya, Siddhartha; Wilson, Timothy D

2015-01-01

The discrete anatomy of the eye's intricate oculomotor system is conceptually difficult for novice students to grasp. This is problematic given that this group of muscles represents one of the most common sites of clinical intervention in the treatment of ocular motility disorders and other eye disorders. This project was designed to develop a digital, interactive, three-dimensional (3D) model of the muscles and cranial nerves of the oculomotor system. Development of the 3D model utilized data from the Visible Human Project (VHP) dataset that was refined using multiple forms of 3D software. The model was then paired with a virtual user interface in order to create a novel 3D learning tool for the human oculomotor system. Development of the virtual eye model was done while attempting to adhere to the principles of cognitive load theory (CLT) and the reduction of extraneous load in particular. The detailed approach, digital tools employed, and the CLT guidelines are described herein. © 2014 American Association of Anatomists.

2017-09-01

With a perceptive eye cast on geoscience pedagogy for students labeled as disabled, Martinez-Álvarez makes important contributions to the existing conversation on placed-based learning. It is in our local backyards, from the corner basketball court, to the mud bank of a city lake, to the adjacent field where rocky outcrops spill down to a forgotten farmer's field, that we find rich working material for connecting self and community, moving students' out-of-school experiences that feature their cultural and linguistic knowledge, from misconceptions to "alternative conceptions." Informed by her insights regarding the learning of students whose literacy does not match conventional classroom practice, geoscience learning in the place of third space can act as a model of meaning making across the entire curriculum. In the pages that follow, I transact, both aesthetically and efferently, with Martinez-Álvarez's text as she presents her research on special ways of learning in placed-based geoscience explorations with bilingual children experiencing disabilities.

Unpacking students' atomistic uderstanding of stoichiometry

Science.gov (United States)

Baluyut, John Ysrael

Despite the use by instructors of particulate nature of matter (PNOM) diagrams in the general chemistry classroom, misconceptions on stoichiometry continue to prevail among students tasked with conceptual problems on concepts of limiting and excess reagents, and reaction yields. This dissertation set out to explore students' understanding of stoichiometry at the microscopic level as they solved problems that using PNOM diagrams. In particular, the study investigated how students coordinated symbolic and microscopic representations to demonstrate their knowledge of stoichiometric concepts, quantified the prevalence and explained the nature of stoichiometric misconceptions in terms of dual processing and dual coding theories, and used eye tracking to identify visual behaviors that accompanied cognitive processes students used to solve conceptual stoichiometry problems with PNOM diagrams. Interviews with students asked to draw diagrams for specific stoichiometric situations showed dual processing systems were in play. Many students were found to have used these processing systems in a heuristic-analytic sequence. Heuristics, such as the factor-label method and the least amount misconception, were often used by students to select information for further processing in an attempt to reduce the cognitive load of the subsequent analytic stage of the solution process. Diagrams drawn by students were used then to develop an instrument administered over a much larger sample of the general chemistry student population. The robustness of the dual processing theory was manifested by response patterns observed with large proportions of the student samples. These response patterns suggest that many students seemed to rely on heuristics to respond to a specific item for one of two diagrams given for the same chemical context, and then used a more analytic approach in dealing with the same item for the other diagram. It was also found that many students incorrectly treated items

To be competitive in 21st century science and exploration careers, graduate students in planetary science and related disciplines need mentorship and need to develop skills not always available at their home university, including fieldwork, mission planning, and communicating with others in the scientific and engineering communities in the U.S. and internationally. Programs offered by the Lunar and Planetary Institute (LPI) address these needs through summer internships and field training programs. From 2008-2012, LPI hosted the Lunar Exploration Summer Intern Program. This special summer intern program evaluated possible landing sites for robotic and human exploration missions to the lunar surface. By the end of the 2012 program, a series of scientifically-rich landing sites emerged, some of which had never been considered before. Beginning in 2015 and building on the success of the lunar exploration program, a new Exploration Science Summer Intern Program is being implemented with a broader scope that includes both the Moon and near-Earth asteroids. Like its predecessor, the Exploration Science Summer Intern Program offers graduate students a unique opportunity to integrate scientific input with exploration activities in a way that mission architects and spacecraft engineers can use. The program's activities may involve assessments and traverse plans for a particular destination or a more general assessment of a class of possible exploration targets. Details of the results of these programs will be discussed. Since 2010 graduate students have participated in field training and research programs at Barringer (Meteor) Crater and the Sudbury Impact Structure. Skills developed during these programs prepare students for their own thesis studies in impact-cratered terrains, whether they are on the Earth, the Moon, Mars, or other solar system planetary surface. Future field excursions will take place at these sites as well as the Zuni-Bandera Volcanic Field. Skills

A qualitative study to explore the issues for patients and students when giving feedback on the communication of dental students. The Department of Health and National Institute for Health Research are committed to involving patients in improving clinical education, research and service delivery. Yet, there is a limited body of evidence on the perceptions of patients when asked to be involved in this way, and specifically when asked to provide feedback on the communication skills of dental students. This study seeks to address this gap and heighten the understanding of the issues faced by patients when asked to be involved in clinical education. Data were collected using focus groups with dental students (n=10) and patients (n=8) being treated by these students. Both groups were asked about their thoughts, feelings and beliefs about patients being asked to provide feedback on the communication skills of dental students. Data analysis involved inductive thematic analysis of transcribed audio recordings. Four themes emerged from the data: "legitimacy," "co-educators," "maintaining the equilibrium of the patient-student relationship" and the "timing of patient feedback." Support for involving patients in giving feedback on students' communication skills was established, with patients considering they were best placed to comment on the communication skills of dental students. Patients and students do not want to provide feedback alone and want support to assist them, especially if feedback was negative. Issues of anonymity, confidentiality and ownership of the feedback process were worrisome, and the positioning of patient feedback in the programme was seen as critical. Patients and students are willing to engage in patient feedback on students' communication skills, and with support and training, the concerns around this are not insurmountable and the benefits could potentially profit both groups. These findings have resonance with other healthcare educators when

The eye amputated - consequences of eye amputation with emphasis on clinical aspects, phantom eye syndrome and quality of life

In this thesis the term eye amputation (EA) covers the removing of an eye by: evisceration, enucleation and exenteration. Amputation of an eye is most frequently the end-stage in a complicated disease, or the primary treatment in trauma and neoplasm. In 2010 the literature is extensive due...... to knowledge about types of surgery, implants and surgical technique. However, not much is known about the time past surgery. THE PURPOSE OF THE PHD THESIS WAS: To identify the number of EA, the causative diagnosis and the indication for surgical removal of the eye, the chosen surgical technique...... and to evaluate a possible change in surgical technique in Denmark from 1996 until 2003 (paper I); To describe the phantom eye syndrome and its prevalence of visual hallucinations, phantom pain and phantom sensations (paper II); To characterise the quality of phantom eye pain, including its intensity...

Design, Sensing and Control of a Robotic Prosthetic Eye for Natural Eye Movement

Full Text Available Loss of an eye is a tragedy for a person, who may suffer psychologically and physically. This paper is concerned with the design, sensing and control of a robotic prosthetic eye that moves horizontally in synchronization with the movement of the natural eye. Two generations of robotic prosthetic eye models have been developed. The first generation model uses an external infrared sensor array mounted on the frame of a pair of eyeglasses to detect the natural eye movement and to feed the control system to drive the artificial eye to move with the natural eye. The second generation model removes the impractical usage of the eye glass frame and uses the human brain EOG (electro-ocular-graph signal picked up by electrodes placed on the sides of a person's temple to carry out the same eye movement detection and control tasks as mentioned above. Theoretical issues on sensor failure detection and recovery, and signal processing techniques used in sensor data fusion, are studied using statistical methods and artificial neural network based techniques. In addition, practical control system design and implementation using micro-controllers are studied and implemented to carry out the natural eye movement detection and artificial robotic eye control tasks. Simulation and experimental studies are performed, and the results are included to demonstrate the effectiveness of the research project reported in this paper.
